[0069] To make the technical contents, technical steps, purposes and effects of the present application clear, the following will be described in detail in conjunction with the embodiments and the accompanying drawings.

[0070] Embodiment One

[0071] In the modern fast-paced life, the demand for portable cleaning tools is gradually increasing. Users want to be able to clean at any time and any place, but the traditional cleaning equipment is often bulky and not easy to carry. The portable dust removal equipment 10 of the present application meets the dual needs of users for cleaning efficiency and portability through miniaturized design.

[0072] As shown in FIGS. 1 and 2, the portable dust removal equipment 10 includes a shell 100, a cleaning accessory 200, a driving source 300, a filter assembly 400, and a wind pressure assembly 500. The shell 100 is a hand-held mini shell with a cavity 101 inside the shell 100, and a dust suction port 102 communicating with the outside is arranged at one end of the cavity 101; the cleaning accessory 200 is arranged in the cavity 101 and at least partially protrudes from the dust suction port 102; the driving source 300 is arranged in the cavity 101, which is used to drive the cleaning accessory 200 to move, so as to clean the surface to be cleaned close to the dust suction port 102 through the cleaning accessory 200; the wind pressure assembly 500 is arranged in the cavity 101, which is used to generate wind pressure in the cavity 101, so as to suck the garbage on the surface to be cleaned into the cavity 101 through the dust suction port 102; the filter assembly 400 is used to filter the garbage sucked into the cavity 101.

[0073] Specifically, the shell 100 of the portable dust removal equipment 10 is a humanized hand-held mini shell, which is carefully designed in structure to be small and easy to carry. The shell 100 is internally provided with a cavity 101 for cleaning, which constitutes the basic framework of the dust removal equipment 10.

[0074] In some embodiments, as shown in FIG. 1, the appearance style of the portable dust removal equipment 10 is mainly presented by the shell 100. In order to facilitate the user to hold, the shape of the shell 100 can be an elongated cylindrical shell structure, and its size is also more miniaturized compared with the existing dust removal equipment, with a diameter of about 2.5 centimeters and a length of about 15 centimeters, i.e. the shape and size of the portable dust removal equipment 10 is slightly close to the pen used in daily life, thereby facilitating the user to hold and use such cleaning precision small equipment.

[0075] In some embodiments, the shell 100 is a hollow structure, i.e. has a cavity 101 inside the shell 100, and a dust suction port 102 is arranged at one end of the cavity 101 to communicate with the outside world, and an air outlet 103 is arranged at the other end to communicate with the outside world, wherein the dust suction port 102 is close to the surface to be cleaned, and is used to suck the garbage swept on the surface to be cleaned, and the air outlet 103 is used to ensure smooth airflow to discharge filtered air, thereby improving the overall cleaning efficiency of the device. At the same time, the mini design of the cavity 101 ensures the flexibility of the device during use.

[0076] The specific shape and size of the shell 100 only need to meet the convenience of user holding and mini size compared with existing devices, and are not specifically limited in the embodiments of the present application. For example, in other embodiments, the shell 100 can be a shell structure with an elliptical cross section, or a relatively short and thick shape with a large diameter, and the specific size can also be other values.

[0077] In some embodiments, as shown in FIG. 2, the portable dust removal device 10 of the present application realizes the miniaturization of the shell 100 and the orderly arrangement of the internal components through its unique structural design. For example, from the dust suction port 102 to the air outlet 103 of the cavity 101, the cleaning accessory 200, the driving source 300, the air pressure assembly 500, the filter assembly 400 and other components (such as battery, wind deflector, etc.) of the portable dust removal device 10 are combined in sequence, thereby forming a complete portable dust removal device 10. Among them, the cleaning accessory 200, the driving source 300, the air pressure assembly 500 and the filter assembly 400 are connected in sequence in the cavity 101 to form a compact and efficient cleaning system, so that powerful cleaning performance can be achieved without occupying too much space.

[0078] In some embodiments, each component in the portable dust removal device 10 is detachably connected to the shell 100 or other components, so that the assembly and subsequent disassembly of each component are more convenient and efficient.

[0079] In some embodiments, one end of the cleaning accessory 200 is a mounting end for mounting on the output shaft of the driving source 300 to realize power transmission between the cleaning accessory 200 and the driving source 300, and the other end is a cleaning end for cleaning the surface to be cleaned under the drive of the driving source 300.

[0080] Optionally, the surface to be cleaned can be a flat surface or a concave-convex surface, a hard surface or a soft surface, etc., and for different types of surfaces to be cleaned, the user can also replace the corresponding matching cleaning accessory 200 for cleaning to effectively clean the surface to be cleaned. Therefore, the cleaning accessory 200 is designed to be compact and can flexibly meet the cleaning needs of different surfaces and environments.

[0081] In an embodiment, in order to ensure the strength of the mounting end of the cleaning accessory 200 and prevent the excessively long mounting end and output shaft from being deformed or damaged under stress, the cleaning accessory 200 can be partially arranged outside the suction port 102 from the cavity 101, but in other embodiments, the mounting end can also be arranged without extending into the suction port 102, that is, the cleaning accessory 200 is arranged entirely outside the suction port 102, and in this case, the mounting end and the output shaft are fixedly assembled with the output shaft partially extending outside the suction port 102.

[0082] In some embodiments, the driving source 300 is installed in the cavity 101 and arranged behind the cleaning accessory 200, responsible for driving the movement of the cleaning accessory 200 to realize the cleaning capability of the device. The driving source 300 is a detachable driving motor, which can be a rotating motor, a vibration motor, or an ultrasonic wave generating device, etc.

[0083] For example, the driving source 300 can be a rotating motor, which is used to drive the cleaning accessory in a rotating manner to clean the surface to be cleaned. The rotating motor can be used in scenarios of cleaning oil stains or fingerprint marks on the surface, which can provide stable rotating power for the cleaning accessory 200, so that the cleaning accessory 200 effectively contacts the cleaning surface to efficiently remove the attached stains without damaging the surface.

[0084] For another example, the driving source 300 can be a vibration motor, which is used to drive the cleaning accessory in a vibrating manner to clean the surface to be cleaned. The vibration motor can be used in scenarios of cleaning dust attachments on the surface, and the fine vibration generated by the vibration motor can effectively loosen and shake off the dust attached to the surface, enhancing the cleaning effect, especially when dealing with fabrics or uneven surfaces.

[0085] For some specific scenarios, such as stubborn stains or deep cleaning of fine particles, the driving source 300 can be an ultrasonic wave generating device, so as to achieve the deep cleaning effect of the cleaning surface through the high-frequency sound waves generated by the ultrasonic wave generating device.

[0086] The use of rotating motors, vibration motors, and ultrasonic wave generating devices provides the driving source 300 with optimal solutions for different cleaning needs, thereby meeting the cleaning requirements of households, industries, and special environments.

[0087] In some embodiments, the air pressure assembly 500 is located in the cavity 101 and is arranged behind the filter assembly 400, for generating air pressure in the cavity 101, which functions to suck the garbage on the surface to be cleaned into the cavity 101 through the suction port, which is effectively implemented in the mini space and enhances the dust collection capacity of the device.

[0088] In some embodiments, the air pressure assembly 500 can include a motor and a fan blade, the motor is fixedly installed on the shell 100 and is accommodated in the cavity 101, and the fan blade is sleeved on the power shaft of the motor, so that the motor can drive the fan blade to rotate, thereby generating air pressure in the cavity 101 and causing gas flow in the cavity 101, so that the garbage on the surface to be cleaned is sucked into the cavity 101 through the suction port 102.

[0089] In some embodiments, the filter assembly 400 is arranged in the cavity in sequence and is located between the air pressure assembly 500 and the driving source 300, which functions to effectively filter the garbage entering the cavity 101, ensure the cleaning effect, prevent the garbage from flowing back to the environment, and improve the safety of user use.

[0090] In some embodiments, the filter assembly 400 can be a microporous ceramic filter screen for filtering larger particles of dust, and / or a metal screen which is low in cost and good in filtering effect, and / or a sponge filter layer for filtering larger substances in the air, and / or a hepa filter layer for filtering smaller particles, and the filtering effect is better when used in combination.

[0091] In a specific implementation scenario, when the portable dust removal device 10 is working, first, the driving source 300 drives the cleaning accessory 200 to move, so that the cleaning accessory 200 sweeps the garbage on the surface to be cleaned; then the air pressure assembly 500 drives the fan blade to rotate, thereby generating air pressure in the cavity 101 to suck the garbage on the surface to be cleaned into the cavity 101 through the suction port 102; finally, the filter assembly 400 filters the air carrying garbage sucked into the cavity 101, so as to discharge the filtered clean air from the air outlet 103.

[0092] As a specific implementation, the portable dust removal device 10 at least includes a handheld dust removal pen for wireless use and a automatic dust removal instrument for automatic opening and closing and dust removal use.

[0093] In some embodiments, the handheld dust removal pen is designed to be wireless, light and portable, and is suitable for handheld use, and the design conforms to ergonomics, is convenient for users to hold for a long time during cleaning, and reduces fatigue. The dust removal pen is suitable for cleaning dust and dirt on desktops, keyboards, window sills and other small areas. Users can move at will through the wireless design, which enhances the convenience and flexibility of operation.

[0094] The automatic dust removal instrument has an intelligent opening and closing function, can independently clean the preset fixed area according to the preset working mode, and can be remotely controlled by the user or automatically opened or closed according to the environmental conditions during work, thereby improving the user's use convenience. At the same time, the dust removal instrument can be connected with other smart devices of the user to realize remote control and timing cleaning function.

[0095] The technical effect of the above scheme is that the device not only avoids the bulkiness and inconvenience of traditional cleaning tools, but also provides a portable, flexible and efficient solution to meet the expectations of modern users for portable cleaning devices. Users can easily carry the device to every corner of daily life and clean at any time to improve the quality of life. Specifically, in one aspect, by distinguishing from the prior art, the cleaning accessory, driving source, wind pressure component and filtering component are housed in the cavity through a handheld mini shell, greatly reducing the physical volume of the dust removal device, realizing the miniaturization of the dust removal device, and improving the portability and operability of the dust removal device. On the other hand, the scheme first uses the driving source to drive the cleaning accessory to clean the surface to be cleaned close to the dust suction port, and then generates wind pressure in the cavity through the wind pressure component to suck the garbage on the surface to be cleaned into the cavity through the dust suction port. Finally, the filtering component in the cavity filters the sucked garbage, thereby realizing the cleaning of dirt such as dust and garbage, effectively improving the cleanliness of dirt in dead corners and gaps, and thus achieving powerful cleaning.

[0096] Those skilled in the art can understand that the structure of the portable dust removal device shown in FIGS. 1 and 2 is only a block diagram of part of the structure related to the scheme of the present application, and does not constitute a limitation on the portable dust removal device to which the scheme of the present application is applied. The specific portable dust removal device can include more or fewer components than those shown in the figures, or combine certain components, or have a different component arrangement.

[0097] Embodiment two

[0098] In the application of portable cleaning devices, how to effectively separate garbage and purify air to improve cleaning efficiency is a key challenge. Traditional designs often cannot effectively distinguish between impurities and clean airflow, limiting the cleaning effect of the device. The present application provides a new type of portable dust removal device 10 by optimizing the shell structure, which can effectively solve this problem.

[0099] Please continue to refer to FIG. 1 and FIG. 2, for the housing 100 in the above embodiment, the housing 100 further comprises a detachable first shell 110 and a second shell 120, the first shell 110 and the second shell 120 jointly enclose a cavity 101, and a dust suction port 102 is arranged at one end of the first shell 110 away from the second shell 120; wherein a filter assembly 400 is installed in the first shell 110 and divides the cavity 101 into an installation cavity 101a and a dust cavity 101b.

[0100] Specifically, the structure of the housing 100 comprises a detachable first shell 110 and a second shell 120, which jointly enclose a cavity 101. This structural design aims to improve the maintainability and operational convenience of the device, and also facilitates the user to clean and maintain the device separately after disassembling it.

[0101] Further, inside the cavity 101, the filter assembly 400 is installed in the first shell 110, which divides the cavity 101 into two areas: the installation cavity 101a and the dust cavity 101b. This design makes the flow of air inside the device more orderly and effectively separates impurities from clean air.

[0102] Further, the dust suction port 102 is arranged at one end of the first shell 110 away from the second shell 120 to ensure that dirt and garbage can be quickly sucked in during the cleaning process. At the same time, the clean airflow after passing through the filter assembly 400 will form in the installation cavity 101a and finally be discharged through the air outlet 103, ensuring that the released air is clean and pollution-free.

[0103] Among them, through the separation effect of the filter assembly 400, the optimization of the airflow direction is realized, so that the garbage on the surface to be cleaned will quickly enter the dust cavity 101b after being sucked into the cavity 101 through the dust suction port 102. The design here can effectively capture and store impurities, greatly reducing the risk of impurities flowing back to the environment with the airflow. At the same time, the clean airflow after filtration can smoothly pass through the installation cavity 101a and be discharged to the air outlet, thereby improving the overall cleaning efficiency.

[0104] In some embodiments, the first shell 110 and the second shell 120 are both elongated cylindrical shell structures, each with a diameter of 2.5 centimeters, and the first shell 110 and the second shell 120 are fixed by screwing. In the assembled state, the length of the housing 100 is about 15 centimeters. The dust cavity 101b and the dust suction port 102 in the shell are coaxially arranged and communicate with each other, and the installation cavity 101a and the dust cavity 101b are both cylindrical in cross-sectional shape, and the cross-sectional shape of the dust suction port 102 is circular.

[0105] The cross sections of the installation cavity 101a, the dust cavity 101b and the dust suction port 102 are circular-shaped to ensure uniform suction force, consistent appearance and consistent thickness of the shell 100. However, the specific shapes of the installation cavity 101a, the dust cavity 101b and the dust suction port 102 can also be other styles, for example, the cross sections of the installation cavity 101a and the dust cavity 101b can also be elliptical or polygonal, the cross section of the dust suction port 102 can be a waist-shaped or rectangular polygon, and the position of the dust suction port 102 can be offset from the axis of the dust cavity 101b. In addition, in other embodiments, the first shell 110 and the second shell 120 can also be fixed by clamping or inserting, or can be opened and closed by a shaft connection and a locking structure, which is not limited here.

[0106] In addition, in the embodiments of the present application, the airflow direction refers to the direction of the gas flowing in the cavity 101. The airflow direction is generally the axis direction of the first shell 110 and the second shell 120. Due to the blocking effect of the air guide structure and the internal parts, the airflow direction may slightly deviate in the radial direction of the cavity 101 at some positions of the cavity 101. The airflow direction described in the limiting direction refers to the axis direction of the first shell 110 and the second shell 120. The outer contour of the first shell 110 and the second shell 120 is cylindrical, and the axis is the central axis of the corresponding cylinder.

[0107] The technical effect of the above scheme is that by designing the cavity of the shell into an installation cavity and a dust cavity, more efficient garbage separation and airflow optimization are achieved. After the cleaning airflow flows through the filter assembly, it can ensure that impurities are effectively isolated, and the purified air is safely discharged. In addition, the shell structure improves the use stability and cleaning performance of the equipment, not only optimizes the cleaning effect, but also greatly improves the user experience. In summary, the portable dust removal equipment of the present application significantly improves the cleaning efficiency and airflow management capability through the unique shell structure design, which can meet the multiple needs of modern users for efficient and convenient cleaning equipment.

[0108] Embodiment three

[0109] In modern cleaning equipment, the cleaning method of the cleaning part is crucial to the cleaning effect. Traditional cleaning accessories often lack efficient driving devices, resulting in unstable movement during cleaning and affecting the cleaning quality and efficiency. Therefore, there is an urgent need for a new type of cleaning accessory that can achieve efficient cleaning of the surface to be cleaned through efficient output shaft driving design.

[0110] Referring to FIG. 3 and FIG. 4, for the cleaning accessory 200 in the above embodiment, the cleaning accessory 200 comprises a base 210 and a cleaning part 220, wherein the base 210 is mounted on the output shaft 310 of the driving source 300, and the cleaning part 220 is fixed to the base 210, so that the cleaning part 220 is in motion to clean the surface to be cleaned under the driving of the output shaft 310.

[0111] In some embodiments, the side of the base 210 away from the cleaning part 220 is provided with a mounting shaft 212 with a cross section of a regular hexagon, and the output shaft 310 of the corresponding driving source 300 is also provided with a mounting hole (not shown in the figure) with a regular hexagonal shape, and the mounting shaft 212 is mounted on the output shaft 310 in a plug-in manner to realize the power transmission between the cleaning accessory 200 and the first driving source 300, so as to ensure that the cleaning accessory 200 can stably operate while bearing the dynamic force.

[0112] In some embodiments, the mounting shaft 212 can be made of a magnetic material, and the end of the output shaft 310 of the driving source 300 is also provided with a magnetic material, and the magnetism of the two is opposite, so that the cleaning accessory 200 is mounted in a plug-in manner, and is also detachably mounted in a magnetic manner. Compared with the plug-in mounting manner, the magnetic assembly is more labor-saving and easy to assemble, and has a sense of use when it is assembled in place.

[0113] In some embodiments, the base 210 can be a solid cylindrical ring structure, and the cleaning part 220 is fixed to the side of the base 210 close to the dust suction port 102, and the diameter of the base 210 is smaller than that of the dust suction port 102, so that the airflow carrying impurities is sucked into the dust suction port 102 from the outside of the circumference of the base 210.

[0114] In some embodiments, the base 210 is designed to have a solid cylindrical ring structure, so that the base 210 has good stability and bearing capacity, can bear the kinetic energy in the cleaning process, and is convenient to connect with the dust collection system. Moreover, the diameter of the base 210 is designed to be smaller than that of the dust suction port 102, so that the base 210 can effectively combine with the dust suction port 102, and ensure that the airflow path is unobstructed, which provides favorable conditions for subsequent dust collection.

[0115] The technical effect of the above scheme is that by fixing the cleaning part 220 to the base 210, it is ensured that the cleaning part 220 will not displace or fall off during the movement, so that the cleaning part 220 can effectively clean the surface to be cleaned in a motion manner under the driving of the output shaft 310 of the driving source 300.

[0116] Further, referring to FIG. 5, the cleaning portion 220 can be cleaning bristles, and the cleaning bristles are arranged in an array on the root of the base 210, wherein the base 210 is provided with a mounting fence 211 on the side where the cleaning bristles are mounted, and the mounting fence 211 is used to partially enclose the cleaning bristles.

[0117] The design of the mounting fence 211 aims to limit the movement of the cleaning bristles within its fence area. This measure ensures that the bristles have a clear range of motion during cleaning, avoiding excessive movement that can cause bristle failure or omission of the cleaning area. In addition, the cleaning bristles have good flexibility and adaptability, which can effectively clean various surface impurities and dirt. And the cleaning bristles are arranged in an array on the root of the base 210, which can ensure uniform distribution of the cleaning bristles and provide a larger contact area, thereby improving the cleaning effect.

[0118] In another embodiment, referring to FIG. 5, the cleaning portion 220 can be cleaning bristles, and the cleaning bristles are arranged in an array on the root of the base 210, wherein the base 210 is provided with a mounting shaft 212 that can rotate at a certain angle on the side away from the bristles, and the mounting shaft 212 is inserted and mounted on the output shaft 310 of the driving source 300, so that when the driving source 300 drives the base 210, the cleaning bristles can rotate within a predetermined angle range.

[0119] The rotatable mounting shaft 212 allows the cleaning bristles to move flexibly within a certain angle range, thereby adapting to different surface shapes and cleaning requirements at different angles. This design makes the cleaning action more efficient and can better remove dirt and debris. In addition, by adjusting the action angle of the bristles, the cleaning portion 220 can perform better in different cleaning conditions. This means that even on complex surface structures, the cleaning bristles can achieve a deeper cleaning effect.

[0120] In other embodiments, the type of cleaning accessory 200 can be replaced, including a first type of cleaning accessory in which the cleaning portion 220 is suede, or a second type of cleaning accessory in which the cleaning portion 220 is a brush, wherein the suede is used for cleaning oil or fingerprint marks on the surface, and the brush is used for cleaning dust and other attachments on the surface.

[0121] In some embodiments, the user can choose different cleaning accessories 200 according to the cleaning needs. For the suede type cleaning portion 220, it can effectively remove stains without damaging the cleaning surface due to the unique texture and softness of the suede. For the brush type cleaning portion 220, the rigidity and dense bristle layout of the brush allow it to quickly and effectively collect and remove particles on the surface when sweeping dust.

[0122] The technical effect of the above scheme is that by arranging the mounting fence or the movable mounting shaft on the base, the active area of the cleaning bristles is effectively limited, and the cleaning effect and the durability of the bristles are improved. This innovative design not only ensures effective coverage of the cleaning action, but also provides users with a more convenient operation experience. In addition, through the design of the detachable cleaning accessory, combined with different types of cleaning parts, various cleaning needs can be effectively met. Whether it is suede for oil stains and fingerprint marks, or a brush for removing dust and other attachments, the best cleaning effect can be provided in different scenarios.

[0123] Please refer to FIGS. 6 and 7, in another embodiment of the present application, a cleaning accessory 200' is also provided, which includes a base 210' and a cleaning part 220' fixed to the base 210'.

[0124] In some embodiments, as shown in FIGS. 6 and 7, the above-mentioned base 210' includes a first base body 211', a connecting body 212' and a second base body 213' connected in sequence, wherein the first base body 211' is a cylindrical ring structure, the first base body 211' is coaxially provided with a cylindrical suction hole 211a', the second base body 213' is a cylindrical structure, and the outer diameter of the second base body 213' is smaller than that of the first base body 211', the second base body 213' is provided with a mounting shaft 213a' on the side away from the first base body 211', the connecting body 212' is a rod structure, and the connecting body 212' is arranged at an angle of 20° with the axis of the first base body 211', the number of connecting bodies 212' is three, and the three connecting bodies 212' are arranged in a circumferential array around the axis of the first base body 211', one end of the connecting body 212' is connected to the first base body 211', and the other end is connected to the second base body 213'.

[0125] When a user uses it, after starting the cleaning accessory 200', the garbage swept by the cleaning part 220' is first sucked into the suction hole 211a' of the first base body 211', and then is sucked into the dust suction port 102 around the side of the second base body 213'. In some embodiments, the structure of the base 210' facilitates the suction of the swept garbage into the dust removal equipment 10, and the garbage does not need to be sucked into the dust chamber 101b after being swept to the outside of the first base body 211', because the outside of the first base body 211' deviates from the dust suction port 102, so the suction force here is smaller, and the garbage is not easy to be sucked into the dust chamber 101b.

[0126] The outer contours of the first base body 211', the second base body 213', and the suction hole 211a' are all provided in a cylindrical shape, so that the cleaning accessory 200' runs more smoothly during the process of rotary cleaning, and the suction force of the dust removal equipment 10 for sucking the garbage swept by the cleaning accessory 200' is more balanced. In other embodiments, the outer contours of the first base body 211', the second base body 213', and the suction hole 211a' can also be an ellipse or a polygon such as a triangle, a rectangle, a hexagon, etc., which are not limited here.

[0127] The connecting body 212' is arranged at an angle of 20° with the axis of the first base body 211', so as to reduce the outer diameter of the second base body 213' while ensuring the connection strength between the first base body 211' and the second base body 213', and reasonably avoiding the air flow passage. In other embodiments, the angle between the connecting body 212' and the axis of the first base body 211' can also be 35°, 40°, or 53°, or in some embodiments, the outer diameters of the first base body 211' and the second base body 213' are the same, and the connecting body 212' can be arranged vertically with the first base body 211', i.e., the angle between the connecting body 212' and the axis of the first base body 211' is 0°.

[0128] The number of the connecting body 212' is 3, so as to ensure the strength of the base 210' as a whole and the space avoidance of the air flow passage. In other embodiments, the number of the connecting body 212' can also be 2 or 5 or more, and the plurality of connecting bodies 212' are arranged in a circumferential array around the axis of the first base body 211', or the number of the connecting body 212' can be only one while ensuring the connection strength between the first base body 211' and the second base body 213'.

[0129] In some embodiments, the cleaning part 220' is in a cylindrical ring structure, the cleaning part 220' is suede, the cleaning part 220' is fixed to the first base body 211', and the cleaning part 220' does not block the suction hole 211a'. According to the characteristics that the surface fibers of suede and super-fine fiber synthetic leather are relatively fine, the cleaning part 220' can absorb oil stains while sweeping the surface to be cleaned, so that the user can clean the garbage in the area to be cleaned and also wipe off the oil stains or fingerprint marks on the surface to be cleaned when using the dust removal equipment 10, so that the user does not need to clean the oil stains again, which is convenient to operate and has strong cleaning ability. In addition, the specific material of the cleaning part 220' can be suede, or in other embodiments, the cleaning part 220' can also be selected from super-fine fiber synthetic leather or other materials that have certain hardness, wear resistance, and can absorb oil.

[0130] In some embodiments, as shown in FIG. 7, in order to facilitate the installation of the cleaning accessory 200' on the driving source 300, the cleaning accessory 200' is provided with an installation chamfer 213b' on the side of the second base body 213' away from the first base body 211'. When the cleaning accessory 200' is installed on the first housing 110, the base 210' is partially accommodated in the dust cavity 101b, and the installation shaft 213a' on the first base body 211' needs to be first extended into the dust cavity 101b from the dust suction port 102 when the cleaning accessory 200' is installed. The installation chamfer 213b' facilitates the centering and alignment of the cleaning accessory 200' during installation, thereby facilitating the user to disassemble and replace, and further improving the user experience. The installation shaft 213a' is also similarly provided with a fitting chamfer 213a1', which has a similar function to the installation chamfer 213b' described above, and will not be described here.

[0131] Referring to FIG. 8, in another embodiment of the present application, a cleaning accessory 200" is also provided, which comprises a base 210" and a cleaning part 220". For the base 210", the base 210" comprises a first base body 211", a connecting body 212" and a second base body 213" connected in sequence. The first base body 211" is a cylindrical ring structure, the cleaning part 220" is a brush, the cleaning part 220" is fixed on the first base body 211", the first base body 211" is coaxially provided with a cylindrical suction hole 211a", the second base body 213" is a cylindrical structure, and the outer diameter of the second base body 213" is smaller than the outer diameter of the first base body 211", the second base body 213" is provided with an installation shaft 213a" on the side away from the first base body 211", the connecting body 212" is a rod structure, and the connecting body 212" is arranged at an angle of 20° with the axis of the first base body 211", the number of the connecting body 212" is three, and the three connecting bodies 212" are arranged in a circumferential array around the axis of the first base body 211", one end of the connecting body 212" is connected to the first base body 211", and the other end is connected to the second base body 213".

[0132] When the user uses it, after starting the cleaning accessory 200", the garbage swept by the cleaning part is first sucked into the suction hole 211a" of the first base body 211", and then is sucked into the dust suction port 102 around the side of the second base body 213". In some embodiments, the structure of the base 210" facilitates the suction of the swept garbage into the dust removal equipment 10, and the garbage does not need to be sucked into the dust cavity 101b after being sucked around the outside of the first base body 211". Since the outside of the first base body 211" deviates from the dust suction port 102, the suction force here is smaller, and the garbage is not easy to be sucked into the dust cavity 101b.

[0133] The first base body 211", the second base body 213" and the suction hole 211a" are all in a cylindrical shape, so that the cleaning accessory 200" runs more smoothly during the rotation cleaning, and the dust collection equipment 10 has more balanced suction force for sucking the garbage swept by the cleaning accessory 200". In other embodiments, the first base body 211", the second base body 213" and the suction hole 211a" can also be in an oval or polygonal shape, such as a triangle, a rectangle, a hexagon, etc., which is not limited here.

[0134] The connecting body 212" is arranged at an angle of 20° with the axis of the first base body 211", so as to reduce the outer diameter of the second base body 213" and reasonably avoid the air flow channel while ensuring the connection strength between the first base body 211" and the second base body 213". In other embodiments, the angle between the connecting body 212" and the axis of the first base body 211" can also be 35°, 40° or 53°, or in some embodiments, the outer diameters of the first base body 211" and the second base body 213" are the same, and the connecting body 212" can be arranged perpendicularly to the first base body 211", i.e. the angle between the connecting body 212" and the axis of the first base body 211" is 0°, which is not limited here.

[0135] The number of the connecting body 212" is 3, so as to improve the strength of the base 210" as a whole and avoid the space of the air flow channel. In other embodiments, the number of the connecting body 212" can also be 2 or 5 or more, and the plurality of connecting bodies 212" are arranged in a circular array around the axis of the first base body 211", or the number of the connecting body 212" can be only one while ensuring the connection strength between the first base body 211" and the second base body 213".

[0136] Further, referring to FIGS. 9 and 10, the base 210 of the various cleaning accessories 200 can be provided with a storage cavity 211c1" for storing cleaning materials, and the storage cavity 211c1" has a powder outlet hole 211b1" communicating with the outside. When the cleaning accessory 200 moves, the movement path of the powder outlet hole 211b1" at least partially overlaps with the movement path of the cleaning part 220.

[0137] For example, for the above-mentioned first base body 211", the first base body 211" is provided with a hair planting part 211b" and a storage part 211c", wherein the hair planting part 211b" and the storage part 211c" are both in a circular column structure, and have the same cross-sectional profile shape and size, and the hair planting part 211b" and the storage part 211c" are detachably installed by screwing.

[0138] Specifically, as shown in FIG. 9, the cleaning parts 220” can be fixed on the bristle mounting member 211b”, and the plurality of cleaning parts 220” form a cylindrical bristle group 221” in an array arrangement, the cleaning accessory 200” has 5 bristle groups 221”, and the 5 bristle groups 221” are fixed on the bristle mounting member 211b” in a circumferential array around the axis of the bristle mounting member 211b”, the cleaning parts 220” are arranged in a cluster and at intervals, so as to facilitate the dust suction equipment 10 to suck the garbage on the surface to be cleaned, and the garbage is not easy to be stuck between the cleaning parts 220”, and in the case of the same number of cleaning parts 220”, the cleaning parts 220” arranged in a single cluster can reduce the cross-sectional area of the bristle group 221”, and it is also easier for the user to clean the garbage attached to the cleaning parts 220”.

[0139] In other embodiments, the number of bristle groups 221” can be 2, 3, or 7, and the plurality of bristle groups 221” are fixed on the bristle mounting member 211b” in a circumferential array around the axis of the bristle mounting member 211b”, and the cross-sectional shape of the bristle group 221” can also be a polygon such as an ellipse, a triangle, or a rectangle, which is not specifically limited here.

[0140] Specifically, referring to FIGS. 10 and 11, the storage member 211c” is provided with a storage cavity 211c1”, and the storage cavity 211c1” has an opening 211c11” on the side facing the bristle mounting member 211b”, and the bristle mounting member 211b” can block the opening 211c11” when installed on the storage member 211c”. The storage cavity 211c1” is used to store cleaning materials such as carbon powder, talcum powder, or puffy powder, which can absorb grease. Correspondingly, the bristle mounting member 211b” is provided with 5 cylindrical powder outlet holes 211b1” that communicate with the outside, and the 5 powder outlet holes 211b1” are distributed in a circumferential array around the axis of the bristle mounting member 211b”, the powder outlet holes 211b1” and the bristle groups 221” are distributed at intervals and located on the same diameter circular contour line, and the cross-sectional diameter of the powder outlet holes 211b1” is the same as that of the bristle groups 221”.

[0141] The above-mentioned storage cavity 211c1” provided in the base 210 is used to store various suitable cleaning materials, which provides an internal storage space and avoids the complexity of external material storage, and the storage cavity 211c1” has the powder outlet holes 211b1” that communicate with the outside, allowing the cleaning material to be quickly released to the surface to be cleaned when needed.

[0142] As shown in FIG. 12, the arrangement of the storage member 211c” allows the user to release the cleaning powder through the powder outlet hole 211b1” to assist in cleaning while sweeping the surface to be cleaned, thereby improving the user experience. Moreover, the powder outlet hole 211b1” and the bristle group 221” are located on the same diameter circular contour line, and when the cleaning accessory 200” is rotating to clean, the movement path of the powder outlet hole 211b1” and the movement path of the cleaning portion 220 at least partially overlap, i.e., the position of the powder outlet hole 211b1” discharging the powder and the movement trajectory of the cleaning portion 220” overlap, so the user does not need to move the position of the cleaning accessory 200” according to the naked eye, and the bristles can contact and evenly apply the cleaning powder to the surface to be cleaned. Through the above design, the released cleaning material can be accurately dropped on the surface being cleaned during the cleaning process, thereby improving the use efficiency of the cleaning material and ensuring that the cleaning effect can be maximized each time.

[0143] In other embodiments, the cleaning accessory 200” can also be used in other scenarios where the powder needs to be applied to the work area, such as applying magnesium powder with water absorption to the work area. Moreover, the cylindrical arrangement of the powder outlet hole 211b1” and the uniform spacing of the five bristle groups 221” can make the powder discharge of the cleaning accessory 200” more uniform, and the bristle groups 221” can also evenly apply the cleaning powder to the surface to be cleaned.

[0144] Further, in order to control the powder discharge amount of the powder outlet hole 211b1”, the hair planting member 211b” is provided with a non-woven fabric (not shown) corresponding to the position of the powder outlet hole 211b1”. The non-woven fabric is bonded to one side of the hair planting member 211b” facing the storage member 211c”, and the non-woven fabric is used to block the powder in the storage cavity 211c1” from being directly discharged from the powder outlet hole 211b1”, so that the user cannot control the powder discharge amount, thereby causing waste or additional garbage that needs to be cleaned. The arrangement of the non-woven fabric allows the powder in the storage cavity 211c1” to not be directly discharged from the powder outlet hole 211b1” without external force, and the user needs to knock the cleaning accessory 200” on the surface to be cleaned during use when the powder is needed for cleaning, and the powder will be discharged from the powder outlet hole 211b1” to the surface to be cleaned through the fiber holes in the non-woven fabric.

[0145] In order to facilitate the processing and assembly of the non-woven fabric, the non-woven fabric is configured in a circular ring shape and is adapted to the contour of the storage cavity 211c1", but in other embodiments, the specific shape of the non-woven fabric can also be other, for example, the non-woven fabric can be in multiple circular shapes, and multiple non-woven fabrics are individually fixed to the bristle holder 211b" and at least partially shield the powder hole 211b1". In addition, the application does not limit the mounting method of the non-woven fabric on the bristle holder 211b", for example, the non-woven fabric can be set as a separate part and assembled directly in the storage cavity 211c1", and the user needs to take out the non-woven fabric first when replenishing the powder. In addition, the bristle holder 211b" can not be provided with a non-woven fabric, but other fabrics with fiber mesh, such as knitted fabric, etc., so that the powder in the storage cavity 211c1" can seep out of the fabric under the action of external force, thereby achieving the purpose of controlling the powder output.

[0146] In some embodiments, the cleaning part 220" can also be a sponge head or a silica gel head, etc., to achieve the purpose of removing the garbage attached to the surface to be cleaned or uniformly applying the cleaning powder to the working surface. In addition, the detachable installation between the bristle holder 211b" and the storage part 211c" through screwing is to increase the connection area between the bristle holder 211b" and the storage part 211c" to achieve the sealing effect of the storage cavity 211c1", but in other embodiments, the bristle holder 211b" and the storage part 211c" can also be fixedly installed by clamping or bonding and other ways, which are not limited here.

[0147] The technical effect of the above scheme is that through the structural design and functional layout of the cleaning accessory, efficient cleaning material release and cleaning action coordination are achieved. In addition, by combining the movement of the base storage cavity and the cleaning part, the material can be fully utilized every time, ensuring the cleaning effect and improving the use convenience. The design of the cleaning accessory effectively meets the requirements of modern cleaning equipment for high efficiency and convenience, and provides users with better cleaning services.

[0148] Embodiment Four

[0149] In the current design of portable cleaning equipment, how to effectively fix and integrate various components to improve the structural stability and working efficiency of the equipment is an important challenge in design. Especially when connecting the driving source 300 and the cleaning accessory 200, first of all, the structure needs to be firm and the function needs to be efficient. Therefore, the application proposes a unique first mounting assembly 130 to optimize the interaction between the driving source 300 and the cleaning accessory 200 and improve the overall equipment performance.

[0150] Please continue to refer to FIG. 3, the portable dust removal device 10 further comprises a first mounting assembly 130; wherein the first mounting assembly 130 is fixed in the mounting cavity 101a and communicates with the dust cavity 101b, the first mounting assembly 130 is used for covering and fixing the driving source 300, and an opening is arranged on the side of the output shaft 310 of the driving source 300 close to the dust cavity 101b, so that the cleaning accessory 200 is connected to the output shaft 310 of the driving source 300.

[0151] Specifically, the specific features of the first mounting assembly 130 are as follows:

[0152] Covering and fixing function: the design of the first mounting assembly 130 aims to cover and firmly fix the driving source 300. Through appropriate shape and size design, the driving source 300 is ensured not to be easily displaced during the working process, providing good support and stability.

[0153] Connection with the dust cavity 101b: the direct communication of the first mounting assembly 130 with the dust cavity 101b provides convenience for garbage collection in the device, so that the device can quickly transport the inhaled impurities into the dust cavity 101b during the cleaning process, effectively improving the overall cleaning efficiency.

[0154] In addition, in the first mounting assembly 130, the side of the output shaft 310 of the driving source 300 close to the dust cavity 101b is provided with an opening. The design of the opening makes the cleaning accessory 200 can be conveniently connected to the output shaft 310 of the driving source 300, forming an efficient power transmission channel. Such a connection mode enables the driving source 300 to directly drive the cleaning accessory 200 to effectively clean, improves the transmission efficiency, and ensures the flexibility and response speed of the cleaning action.

[0155] Therefore, through the above structure, the first mounting assembly 130 not only contributes to the stability of the device, but also increases the cooperation efficiency between components. The direct connection of the driving source 300 and the cleaning accessory 200 avoids the power loss caused by indirect transmission, thereby improving the cleaning ability and response speed of the device. The design reduces the complexity of the overall device, making it more convenient for maintenance and disassembly in the later stage, further enhancing the user's experience.

[0156] Further, please refer to FIG. 13, the first mounting assembly 130 specifically comprises: a first fixing part 131, a second fixing part 132 and a connecting part 133, wherein the first fixing part 131 covers the driving source 300, the second fixing part 132 is fixed in the cavity 101, the connecting part 133 is fixedly connected to the first fixing part 131 and the second fixing part 132 at both ends, and the first fixing part 132 and the dust cavity 101b are coaxially arranged.

[0157] In some embodiments, the first fixing part 131 is a cylindrical ring structure, and the first fixing part 131 covers the driving source 300, the output shaft 310 of the driving source 300 extends out of the first fixing part 131, and the second fixing part 132 is fixed to the first shell 110 by clamping. The connecting part 133 is a plurality of flat plate structures extending perpendicular to the airflow direction and circumferentially arrayed, the two ends of the connecting part 133 are connected to the first fixing part 131 and the second fixing part 132 respectively, the first fixing part 131 and the dust cavity 101b are coaxially arranged, and the connecting part 133 realizes the installation of the first fixing part 131 on the first shell 110 and also realizes the circulation of the airflow.

[0158] In the above driving source 300, the driving source 300 can be a driving motor, and the first fixing part 131 is specially designed to cover the driving motor to ensure that the driving motor remains stable during the operation of the equipment and prevents displacement or damage caused by vibration or other external factors. The second fixing part 132 can be fixed to the shell 100 (the first shell 110 or the second shell 120) to provide a stable installation basis for the entire first installation assembly 130 and help improve the stability of the overall structure of the equipment. The connecting part 133 serves as a bridge between the first fixing part 131 and the second fixing part 132, allowing the two parts to be firmly connected together, so the design of the connecting part 133 ensures the overall strength of the assembly while providing a necessary passage for gas flow.

[0159] When the driving motor is working, the gas flows through the connecting space between the dust cavity 101b and the first fixing part 131 to form a continuous airflow passage, ensuring the dust removal effect of the cleaning equipment during use. This coaxial structure not only enhances the flowability of the airflow, but also maximizes the reduction of airflow resistance, ensuring that the inhaled impurities are quickly transferred to the dust cavity 101b and improving the cleaning efficiency of the equipment.

[0160] In other embodiments, the second fixing part 132 can be fixed to the first shell 110 by screwing or inserting or other ways, and the second fixing part 132 can also be fixed to the first shell 110. In addition, in some embodiments, the first fixing part 131 can only partially include the driving source 300, and the first fixing part 131 and the dust cavity 101b can be eccentrically arranged.

[0161] The technical effect of the above scheme is that the first installation assembly optimizes the component layout and function integration in the portable dust removal equipment. And the first installation assembly effectively covers and fixes the driving source and provides a convenient connection path, significantly improving the working efficiency of the driving source and the response ability of the cleaning accessory.

[0162] Embodiment five

[0163] In the cleaning device, the filter assembly is one of the key components, which can effectively capture and filter significantly different types of garbage and dirt. The conventional filter system is usually designed as a single filter layer, which is difficult to meet the diversified cleaning needs, and may have low filtering efficiency or clogging problems when dealing with various types of garbage. Therefore, it is particularly important to develop a multi-layer filter assembly to achieve effective filtering of different garbage types.

[0164] Referring to FIG. 14, the filter assembly 400 includes a first filter 410, a second filter 420, and a mounting bracket 430. The first filter 410 is connected to the first mounting assembly 130 and located at one end close to the dust suction port 102. The second filter 420 is connected to the first mounting assembly 130 and connected to the first filter 410. The mounting bracket 430 is connected to the first mounting assembly 130 and located at one end away from the dust suction port 102, and is used to cover the second filter 420. The first filter 410 and the second filter 420 are used to filter different garbage types.

[0165] Further, referring to FIGS. 15 and 16, the mounting bracket 430 is installed in the first housing 110, and the first filter 410, the second filter 420, and the mounting bracket 430 are fixedly connected. The first filter 410 is located upstream of the second filter 420 in the flow direction of the airflow, and the diameter of the particles filtered by the first filter 410 is greater than the diameter of the particles filtered by the second filter 420.

[0166] In some embodiments, referring to FIG. 17, the first filter 410 is a conical ring-shaped side panel structure, that is, in the direction perpendicular to the airflow direction, the first filter 410 has a first end 412 close to the first mounting assembly 130 and a second end 413 away from the first mounting assembly 130. In the airflow direction, the distance from the first end 412 to the dust suction port 102 is less than the distance from the second end 413 to the dust suction port 102. The first filter 410 is sleeved on the first mounting assembly 130, that is, the first mounting assembly 130 penetrates the first filter 410.

[0167] In some embodiments, referring to FIG. 18, the first filter 410 is made of stainless steel, the axis of the conical ring-shaped side surface coincides with the axis of the first housing 110, and a plurality of filter holes 411 are circumferentially arranged on the first filter 410 in the airflow direction. The filter hole 411 is waist-shaped, and in the direction perpendicular to the airflow direction, the short axis of the waist-shaped filter hole 411 and the thickness direction of the ring-shaped filter hole 411 are arranged at a certain angle, so that the area of the filter hole 411 is ensured while the diameter of the filtered particles is reduced, and better filtering effect can be obtained.

[0168] The first filter 410 is designed to effectively capture larger particles such as debris, dust, etc., to prevent them from entering the finer filter layer, thereby ensuring the cleanliness and service life of the subsequent filter. Therefore, the filter holes 411 on the first filter 410 are preferably in a waist shape, but in other embodiments, the filter holes 411 on the first filter 410 can also be circular or other geometric shapes, which are not limited here.

[0169] The first filter 410 is made of stainless steel, which can ensure the strength and corrosion resistance of the first filter 410, so that the first filter 410 can be cleaned and reused. In other embodiments, the first filter 410 can also be made of different other metals or plastics. In addition, in order to facilitate the dumping of garbage and reduce the probability of garbage falling when the user opens the dust chamber 101b, the distance from the first end 412 to the suction port 102 is less than the distance from the second end 413 to the suction port 102, but in other embodiments, the distance from the first end 412 to the suction port 102 is greater than the distance from the second end 413 to the suction port 102, i.e. the first filter 410 in the embodiment is placed upside down in the airflow direction.

[0170] Please continue to refer to FIGS. 15 and 16, the second filter 420 is a ring-shaped cotton fabric structure, the second end 413 is substantially flush with the second filter 420 on the side away from the suction port 102 in the airflow direction, and the second filter 420 is used to filter smaller dust particles than the first filter 410.

[0171] In some embodiments, the second filter 420 is responsible for filtering smaller particles, fine dust, allergens, etc., to improve the cleanliness of the air and the exhaust, and its filtering performance makes the cleaning device more efficient when handling different types of garbage. Therefore, the filter assembly 400 is provided in a two-layer filtering manner, which essentially increases the effective filtering area, thereby increasing the filtering effect and reducing the occurrence of reduced suction due to filter blockage. The diameters of the particles filtered by the first filter 410 and the second filter 420 are different, which facilitates the dumping of garbage and the cleaning of the dust chamber 101b. This multi-layer filtering structure can sequentially capture different sizes and types of garbage, reduce filter blockage, improve overall filtering efficiency, and reduce maintenance frequency.

[0172] In some embodiments, the second filter 420 is made of cotton, which can absorb a small amount of liquid when the suction port 102 sucks in a small amount of liquid, thereby preventing the liquid from being sucked into the dust removal device 10 and damaging the internal structure. The second filter 420 is preferably made of cotton, but in other embodiments, the second filter 420 can also be high-efficiency filter paper or other structures with porous materials.

[0173] In some embodiments, the first filter 410 and the second filter 420 are respectively arranged around the first mounting assembly 130 to divide the cavity 101 into the mounting cavity 101a and the dust cavity 101b. The first filter 410 is designed in a conical ring side surface structure, which can increase the effective area of the first filter 410 and the second filter 420, i.e., increase the effective area of the filter holes 411. In the embodiments of the present application, the housing 100 is designed in an elongated and pen-like size, and the cross-sectional space of the cavity 101 is small. Therefore, the inclined surface can increase the filtering area. In addition, when the second filter 420 is a planar filter, the first filter 410 is arranged in an inclined surface manner to optimize the space and ensure the filtering effect of the second filter 420. If the first filter 410 and the second filter 420 are both arranged in a planar manner, and the space between them is small, the filtering surface of the second filter 420 cannot fully contact the airflow to be filtered, but only the projection overlapping place of the filter holes 411 of the second filter 420 and the first filter 410 can play a filtering role, thereby weakening the filtering effect. In addition, the first filter 410 is arranged in an inclined manner, which is more reasonable in space utilization, and the installation between components is more simple.

[0174] In some embodiments, in order to optimize the space in the dust cavity 101b and reduce the airflow flow resistance, the included angle between the first filter 410 and the first housing 110 axis can be 46°. In other embodiments, the included angle between the first filter 410 and the first housing 110 axis can also be 30°, 50°, 68° and other angles, and the preferred angle range is 25° to 75°. In some embodiments, the first filter 410 can also be an irregular spherical structure to increase the surface area. Herein, the present application is not limited in detail.

The first filter element 410 is fixed to the side of the mounting frame 430 close to the dust suction port 102, and in the vertical direction of the airflow, the diameter of the first filter element 410 and the mounting frame 430 is the same and greater than the diameter of the dust cavity 101b, so as to further reasonably utilize the effective filtering area of the first filter element 410 to increase the filtering effect.

[0176] Wherein, for the specific structure of the mounting frame 430, as long as it can realize the installation of the first filter element 410 and the second filter element 420 on the first shell 110, the present application does not make specific limitation. Wherein, the setting of the mounting plate 433 not only can realize the connection between the first mounting portion 431 and the second mounting portion 432, and the mounting plate 433 can also abut against the second filter element 420 in the airflow direction, so as to realize the limiting and fixing of the second filter element 420 in the airflow direction, in addition, the mounting plate 433 is arranged in a circumferentially spaced manner, which can realize the above-mentioned functions while allowing the filtered gas to flow out of the first shell 110 in the axial direction.

[0177] As shown in FIG. 14 and FIG. 16, the outer side of the second mounting portion 432 is provided with an annular groove 432a, and the portable dust removal equipment 10 further comprises a sealing ring 600, the annular groove 432a is used for accommodating the sealing ring 600, and the sealing ring 600 is also arranged between the first mounting assembly 130 and the mounting frame 430, so as to realize the airway sealing of the annular middle part and the peripheral side of the filter assembly 400, thereby avoiding the accumulation of dust in the gap and the loss of wind power.

[0178] As shown in FIG. 16, the first filter element 410 further comprises a reinforcing ring 414, the reinforcing ring 414 is arranged on the side of the first end 412 away from the dust suction port 102, and the reinforcing ring 414 extends in the direction of the airflow, the arrangement of the reinforcing ring 414 can increase the strength of the first filter element 410, reduce the deformation of the first filter element 410 under the impact of the airflow and garbage, thereby improving the service life of the first filter element 410.

[0179] Continuing as shown in FIG. 16, the second mounting portion 432 is provided with a handle portion 432b on the side facing away from the dust suction port 102 in the airflow direction. The handle portion 432b is a hook-shaped structure integrally formed with the second mounting portion 432. The handle portion 432b facilitates the user to take out the filter assembly 400 from the first shell 110 when the first shell 110 and the second shell 120 are disassembled, thereby improving the user experience. In order to increase the volume of the handle portion 432b and facilitate the user to hold it, the handle portion 432b is provided on the second mounting portion 432, but in other embodiments, the handle portion 432b can also be provided on the first mounting portion 431, which is not limited here.

[0180] The technical effect of the above scheme is that through the reasonable structural design of the first filter element, the second filter element, and the mounting frame of the filter assembly, effective filtration of multiple types of garbage is achieved. This innovative design not only improves the filtration efficiency and service life of the cleaning device, but also optimizes the cleaning effect and is suitable for various cleaning scenarios.

[0181] In an embodiment, referring to FIG. 19, the filter assembly 400 further includes a filter cotton 440 accommodated in the cavity 101 and located at one end close to the air outlet 103. The filter cotton 440 is used for performing a third filtration on the airflow that has been subjected to double filtration, and the dust particles filtered by the filter cotton 440 all have a diameter less than that of the first filter element 410 and the second filter element 420.

[0182] In some embodiments, the filter cotton 440 can ensure that the gas discharged to the outside through the air outlet 103 is clean and harmless, and its placement at the air outlet 103 can be used to shield the component architecture inside the dust removal device, thereby achieving the purpose of "hiding ugliness". The filter cotton 440 can be washed and reused, and in other embodiments, the filter cotton 440 can also be made of other materials, which is not limited in the present application.

[0183] The design of the filter cotton 440 focuses on the following aspects:

[0184] Filtering fine particles: The filter cotton 440 can capture fine particulate matter such as dust, pollen, dirt, and other pollutants in the airflow, preventing harmful substances that have not been inhaled from being released into the air again.

[0186] Protecting the motor and internal components: The filter cotton 440 can prevent larger particles from entering the inside of the dust collector, thereby protecting the motor and other components from damage and prolonging the service life of the device.

[0187] Noise reduction: The filter cotton 440 can absorb noise to some extent, reducing the noise generated when air is discharged, and improving the user experience.

[0188] In an embodiment, an antibacterial agent and / or a chemical adsorbent are added to the filter cotton 440; wherein the antibacterial agent is used to kill harmful bacteria in the air flow, and the chemical adsorbent is used to adsorb harmful gases in the air flow.

[0189] Specifically, the addition of an antibacterial agent and a chemical adsorbent in the filter cotton 440 can achieve the following important effects:

[0190] Bactericidal disinfection: The antibacterial agent in the filter cotton 440 can inhibit or kill the growth of microorganisms (such as bacteria, fungi, and mold) in the air flow, thereby preventing these harmful microorganisms from being released into the air through the air outlet, protecting indoor air quality, and reducing the risk of respiratory diseases.

[0191] Removal of harmful gases: The chemical adsorbent in the filter cotton 440 can specifically adsorb and remove some harmful gases (such as volatile organic compounds, ammonia, formaldehyde, etc.), which helps to purify the discharged air and reduce the potential harm of harmful gases to the human body, especially in a closed space.

[0192] Improve the filtering effect: The addition of the above-mentioned materials in the filter cotton 440 can enhance the capture ability of small particulate matter and gas, improve the overall air filtration efficiency, and make the dust removal equipment more effective in use.

[0193] Prevent odor: The combination of antibacterial agent and chemical adsorbent in the filter cotton 440 can also remove odor, keep the discharged air fresh, and further improve the user experience.

[0194] Protect the equipment: By filtering pollutants and microorganisms in the air through the filter cotton 440, the internal components of the dust collector can be better protected, and the service life of the equipment can be extended.

[0195] In another embodiment, please continue to refer to FIG. 19, the filter assembly 400 further comprises a sound-absorbing cotton housed in the cavity 101 and located at one end close to the air outlet 103; wherein the sound-absorbing cotton is used to reduce the noise intensity of the air flow discharged from the air outlet 103 by performing noise reduction processing on the air flow after double filtration.

[0196] In some embodiments, the sound-absorbing cotton can ensure that the gas discharged to the outside through the air outlet 103 is clean, and its placement at the air outlet 103 can be used to shield the internal component architecture of the dust removal equipment, thereby achieving the purpose of "hiding ugliness". The sound-absorbing cotton can be washed and reused, and in other embodiments, the sound-absorbing cotton can also be made of other different materials, which is not limited in the present application.

[0197] Among them, the design of the sound-absorbing cotton focuses on the following aspects:

[0198] Noise suppression: Sound-absorbing cotton can effectively absorb sound waves, reducing the noise generated during the operation of the dust collection equipment, thereby reducing the noise level of the air outlet and improving the user experience.

[0199] Improving air quality: Sound-absorbing cotton usually has certain filtering performance, which can help improve the quality of the discharged air, capturing some fine particulate matter, and helping to maintain the cleanliness of the indoor environment.

[0200] Reducing resonance: Sound-absorbing cotton can reduce the resonance produced when air flows in the pipeline, thereby reducing the spread of noise and further reducing the overall noise during equipment operation.

[0201] Improving the perceived quality of the device: By effectively reducing noise, the perceived quality of the vacuum cleaner can be enhanced, making users feel that the device is quieter and more comfortable, thereby improving the market competitiveness of the product.

[0202] Extending the service life of the device: Although the main function is to reduce noise, sound-absorbing cotton can also protect internal components to some extent, avoiding wear and tear caused by vibration and noise, thereby extending the service life of the device.

[0203] Further, the sound-absorbing cotton is mineral wool, or sound-absorbing materials are added to the sound-absorbing cotton.

[0204] Among them, mineral wool is used as sound-absorbing cotton because mineral wool has good sound insulation effect and can absorb the noise generated by air flow, making it an effective material for reducing noise.

[0205] Among them, the sound-absorbing material can include the following examples:

[0206] High-density foam material: such as polyurethane foam, which can effectively absorb sound waves, reduce the spread of noise, and reduce noise during air outlet.

[0207] Glass fiber: has good acoustic properties, can absorb sound waves, reduce echo and noise, and also has certain filtering effect.

[0208] Special sound-absorbing material: specifically designed to reduce noise, which can be used in filter cotton to enhance the noise reduction effect.

[0209] Composite material: such as combining different materials together (such as foam and fiber), which can provide filtering and noise reduction effects at the same time, improving overall performance.

[0210] Coating material: such as rubber or polymer coating, which can provide additional acoustic damping for the filter cotton to reduce noise.

[0211] The technical effect of the above scheme is that the filter cotton added with the antibacterial agent and the chemical adsorbent is arranged at the air outlet of the dust removal equipment, which not only improves the air quality, but also helps to protect the equipment and improve the use environment.

[0212] Embodiment six

[0213] With the continuous upgrading of the functions of portable cleaning equipment, the wind pressure assembly as an important part of the cleaning equipment directly affects the cleaning efficiency of the equipment. How to ensure that the device is small and compact while achieving strong wind pressure and efficient gas flow has become a major challenge in design. The present application provides a high-efficiency portable dust removal equipment by designing a wind pressure assembly, which optimizes airflow management and improves cleaning effect.

[0214] Please refer to FIG. 3 and FIG. 39, the wind pressure assembly 500 specifically includes a wind pressure motor 510 and a centrifugal fan blade 520 arranged in the mounting cavity 101a and located in the second shell 120; wherein the centrifugal fan blade 520 is sleeved on the output shaft 511 of the wind pressure motor 510, and the wind pressure motor 510 drives the centrifugal fan blade 520 to rotate to generate wind pressure in the cavity 101, so that gas flow occurs in the cavity 101.

[0215] Among them, by designing the structure of the wind pressure assembly 500, the wind pressure assembly 500 is arranged in the mounting cavity 101a, and the specific position is located inside the second shell 120. This layout not only effectively utilizes the internal space, but also reduces the overall weight of the equipment and improves portability. Moreover, by designing the configuration of the wind pressure motor 510 and the centrifugal fan blade 520, an efficient wind pressure motor 510 is used for electric drive to provide sufficient power for the overall cleaning equipment, ensuring stable operation under high load conditions, and the centrifugal fan blade 520 is sleeved on the output shaft 511 of the wind pressure motor 510. This design allows the wind pressure motor 510 to directly drive the fan blade to rotate at high speed, thereby forming high-strength wind pressure in the cavity 101.

[0216] Further, please refer to FIG. 39, the centrifugal fan blade 520 further includes a chassis 521 and a blade module 522, wherein the blade module 522 is fixed on the chassis 521 and located on the side of the chassis 521 facing the dust suction port 102, and the chassis 521 is in the shape of a conical side wall and has a mounting hole 521a in the center.

[0217] In some embodiments, for the bottom disc 521, the angle between the conical side wall and the axis can be 63°, and the bottom disc 521 is sleeved on the power shaft 511 of the wind pressure motor 510 through the assembly hole 521a, wherein the projection of the bottom disc 521 on the axis is circular. This can obtain a larger area while ensuring the rotation of the centrifugal fan blade 520 in the installation cavity 101a, thereby increasing the installation area of the blade module 522, and the conical side wall of the bottom disc 521 can increase the actual surface area on the same projection area, thereby increasing the installation area of the blade module 522, and further increasing the contact area between the centrifugal fan blade 520 and the airflow, and increasing the airflow guiding effect.

[0218] In other embodiments, the projection of the bottom disc 521 on the axis can be elliptical or polygonal, and the bottom disc 521 can also be a flat plate structure without inclination or bulge on the axis, or the bottom disc 521 can be directly provided in a solid conical or spherical structure without considering the weight. In addition, the bottom disc 521 can also be provided in a spherical or other bulge structure to increase the projection area of the bottom disc 521 on the axis. When the bottom disc 521 is in the form of a conical side wall, the angle between the conical side wall and the axis can also be 15°, 23°, 35°, 45°, 75°, etc., which is not limited here.

[0219] The conical side wall structure of the bottom disc 521 not only has an attractive shape, but also has important advantages in function. Through optimization design, the actual surface area of the bottom disc 521 is effectively increased compared with the projection area. Such a shape can maximize the installation area of the blades, create conditions for the arrangement of more blades, and arrange the blades more densely, thereby significantly increasing the contact area between the centrifugal fan blade 520 and the airflow. Under the same space limitation, by increasing the friction and pushing effect, the strength of the wind pressure can be improved, effectively meeting the high demand of the portable dust removal equipment 10 in the cleaning process.

[0220] Further, referring to FIG. 39, for the above-mentioned blade module 522 comprising blades 522a, the blades 522a are arranged in a circular array on the base 521 and are arranged in an arc shape, which can be designed to be longer in the same size of the base 521, thereby increasing the contact area of the blades 522a and the wind. In the flow direction of the airflow, the blades 522a have a first side 522a1 upstream and a second side 522a2 downstream, and in the axial direction, the distance from the first side 522a1 to the base 521 is greater than the distance from the second side 522a2 to the base 521, and the distance from the first side 522a1 to the axis is less than the distance from the second side 522a2 to the axis. This design can increase the contact area of the first side 522a1 with the airflow when cutting the wind, thereby increasing the binding force of the airflow, thereby pushing more airflow into the air passage between the blades 522a, and the height of the airflow flowing from the first side 522a1 to the second side 522a2 gradually decreases, the binding ability of the blades 522a to the airflow gradually decreases, releases part of the energy of the airflow, reduces the collision kinetic energy of the airflow out of the fan blade and the second shell 120, reduces the loss of airflow energy, and improves the outflow efficiency.

[0221] Wherein, the axis mentioned for describing the orientation refers to the central axis of the cone body of the conical side wall of the base 521, and in the embodiment of the present application, the base 521 and the second shell 120 are coaxially arranged, that is, in the embodiment of the present application, the axis of the base 521 is also the axis of the second shell 120.

[0222] Further, referring to FIG. 39, in order to further reduce the loss of wind power, the blades 522a are composed of first blades 522b and second blades 522c; wherein the first blades 522b and the second blades 522c are arranged in sequence and are spaced apart, and in the direction perpendicular to the axis, the projection length of the first blades 522b on the base is greater than that of the second blades 522c, and the distance from the first side 522a1 of the first blades 522b to the axis is less than that of the second blades 522c.

[0223] Wherein, the grouping design of the blades 522a can increase the flow area of the blades 522a while ensuring the space of the blades 522a and the airflow inlet, and further, the grouping design of the blades 522a can also perform secondary flow distribution on the airflow, thereby making the airflow flow more uniformly and dispersedly when passing through the centrifugal fan blade 520, and further reducing the loss of wind power.

[0224] In some embodiments, as shown in FIG. 39, the number of first vanes 522b and second vanes 522c is 5, and the 5 first vanes 522b and 5 second vanes 522c are arranged in a circumferential array around the axis, and the first vanes 522b and second vanes 522c are arranged in sequence with a spacing. In the direction perpendicular to the axis, the projection length of the first vanes 522b on the base plate 521 is greater than the projection length of the second vanes 522c on the base plate 521, and the end faces of the second side 522a2 of the first vanes 522b and the second side 522a2 of the second vanes 522c are both circular arcs of the same circle, the distance from the first side 522a1 of the first vanes 522b to the axis is less than the distance from the first side 522a1 of the second vanes 522c to the axis, and in the direction perpendicular to the axis, the distance from the first vanes 522b and the second vanes 522c to the base plate 521 at the same diameter of the base plate 521 is the same.

[0225] In some embodiments, the number and size of the first vanes 522b and the second vanes 522c are designed according to the space layout and the wind loss optimization scheme selected according to the size of the dust removal equipment 10, but in other embodiments, the number of first vanes and second vanes can also be 3, 6 or 9, etc. In addition, in order to simplify the structure and facilitate processing, the vane 522a is composed of the first vane 522b and the second vane 522c, and in other embodiments, the vane 522a can also include a third vane 522a or a fourth vane 522a, etc., which is not specifically limited here.

[0226] Among them, through the hierarchical and spaced arrangement design of the first vanes 522b and the second vanes 522c, the flow direction of the airflow can be more evenly distributed when passing through the centrifugal fan blade 522, avoiding the wind loss caused by the airflow converging at a certain position, and the uniform distribution of the airflow enables each area to fully participate in the airflow pushing process, further improving the overall wind pressure. And the distance from the first side 522a1 of the first vane 522b to the axis is less than the distance from the first side 522a1 of the second vane 522c, so that the first vane 522b can more effectively guide the airflow into the second vane 522c under the action of centrifugal force, thereby achieving the purpose of secondary flow distribution.

[0227] Among them, through the secondary flow distribution of the airflow, the airflow is more evenly distributed, thereby effectively reducing the wind loss and improving the overall performance of the equipment. For example, when the airflow flows uniformly, its kinetic energy can be more fully utilized, avoiding unnecessary energy loss in areas with insufficient pressure. Further, after passing through the carefully designed vane module 520, the airflow can be more effectively converged and pushed, thereby driving more dust and impurities into the equipment and improving the cleaning effect.

[0228] Please refer to FIG. 39 and FIG. 40, in order to converge the airflow to the first side 522a1 of the centrifugal fan blade 520, the air pressure assembly 500 further comprises a wind guide 540, wherein the wind guide 540 is installed on the second shell 120 and located in the installation cavity 101a, the wind guide 540 is located upstream of the centrifugal fan blade 520 in the direction of the airflow, and the wind guide 540 is used to converge the airflow in the direction perpendicular to the airflow direction, and the centrifugal fan blade 520 further guides the airflow converged by the wind guide 540 in the circumferential direction.

[0229] As shown in FIG. 39, the wind guide 540 is annular as a whole, and the first and second recesses 541 and 542 are provided on both sides of the wind guide 540 in the axial direction, and the first and second recesses 541 and 542 are communicated, and the wall thickness of the wind guide 540 is uniform, and the wind guide 540 is a convolution body formed by revolving around the axis close to the sharp corner, and the outer side of the wind guide 540 is provided with a reinforcing rib, so as to increase the strength of the wind guide 540, and avoid deformation of the wind guide 540 under the action of the wind pressure, thereby affecting the converging effect of the wind guide 540. In the direction of the airflow, the first recess 541 is located upstream of the second recess 542, and the first recess 541 is used to converge the airflow from the direction perpendicular to the axis, so as to guide the airflow to the first side 522a1 of the centrifugal fan blade 520, and avoid the wind power loss caused by the dispersion of the airflow. The second recess 542 is used to form an air passage close to the blade 522a and the centrifugal fan blade 520, so as to guide the airflow before entering the blade 522a, further facilitate the airflow, and reduce the wind power loss.

[0230] In other embodiments, the first and second recesses 541 and 542 can also be spherical or other shapes, or the wind guide 540 can be provided in two parts, i.e. the wind guide 540 is provided in two parts, and the first and second recesses 541 and 542 are provided on the two parts respectively, and in some embodiments, without considering the weight of the wind guide 540, the wind guide 540 can also be a solid convolution body structure, which is not limited here.

[0231] Please continue to refer to FIG. 39, in order to facilitate the installation between the centrifugal fan blade 520 and the air pressure motor 510, the mounting hole 521a is provided with a mounting bevel 521a1 on the side close to the air pressure motor 510, so that the centrifugal fan blade 520 can be better sleeved on the power shaft 511 of the air pressure motor 510, thereby facilitating production, reducing assembly time during production, and further reducing production cost.

[0232] In some embodiments, the bottom plate 521 is provided with a reinforcing rib on the side away from the centrifugal fan blade 520 in the axial direction, so as to increase the strength of the centrifugal fan blade 520, avoid deformation of the centrifugal fan blade 520 due to the support under the action of the wind pressure, and thus affect the guiding effect of the centrifugal fan blade 520 and damage the fan blade.

[0233] In order to reduce the weight of the centrifugal fan blade 520, the leaf module 522 is partially protruding from the chassis 521 in the axial direction, and the leaf module 522 is arranged in an outwardly inclined manner, which can reduce the projected area of the chassis 521, i.e., reduce the volume of the chassis 521, while ensuring the same flow area, thereby reducing the weight of the centrifugal fan blade 520 and the weight of the dust removal equipment 10, facilitating user movement and use, and improving user experience.

[0234] The technical effect of the present scheme is that the modular design of the above-mentioned air pressure assembly not only simplifies the assembly process, but also improves the assembly efficiency and saves production costs. In addition, with the high-speed rotation of the centrifugal fan blade, the gas inside the cavity is quickly sucked and pressurized, thereby forming a powerful air pressure in the cavity. This air pressure can effectively suck the garbage on the surface to be cleaned into the cavity, improving the cleaning efficiency. This design effectively improves the overall performance of the equipment, ensuring a quick and thorough cleaning process.

[0235] In an embodiment, referring to FIGS. 25 and 26, the centrifugal fan blade 520 includes a first side A1 near the center of the chassis and a second side A2 near the edge of the chassis, and the shape of the centrifugal fan blade 520 between the first side A1 and the second side A2 presents an arc shape, and the height of the centrifugal fan blade 520 between the first side A1 and the second side A2 gradually decreases, so as to increase the contact area with the suction airflow when the centrifugal fan blade 520 cuts the wind.

[0236] Specifically, the centrifugal fan blade 520 is arc-shaped, and the centrifugal fan blade 520 is distributed in a circumferential array on the chassis 521. The arc-shaped arrangement of the centrifugal fan blade 520 can design longer in the same size of the chassis 521, thereby increasing the contact area of the centrifugal fan blade 520 and the wind. In the flow direction of the airflow, the centrifugal fan blade 520 has a first side A1 located upstream and a second side A2 located downstream. In the axial direction, the distance from the first side A1 to the chassis 521 is greater than the distance from the second side A2 to the chassis 521. This design can increase the contact area of the first side A1 with the airflow when cutting the wind, thereby increasing the binding force of the airflow, thereby pushing more airflow into the air duct between the centrifugal fan blades 520. In addition, the height of the airflow from the first side A1 to the second side A2 gradually decreases, the binding ability of the centrifugal fan blade 520 to the airflow gradually decreases, releases part of the energy of the airflow, reduces the collision kinetic energy of the airflow out of the fan blade with the second shell 120, reduces the loss of airflow energy, and improves the air outlet efficiency.

[0237] In some embodiments, as shown in FIG. 25, the projection of the base 521 in the positive direction thereof presents a circular shape, and a plurality of centrifugal fan blades 520 are arranged in sequence in a clockwise direction around the base 521. Each centrifugal fan blade 520 includes a first side A1 close to the center of the base and a second side A2 close to the edge of the base, and the centrifugal fan blade 520 presents an arc shape between the first side A1 and the second side A2. Further, as shown in FIG. 5, in the axial direction of the base 521, the height of each centrifugal fan blade 520 gradually decreases between the first side A1 and the second side A2, so that the centrifugal fan blade 520 presents a conical shape as a whole on the base 521. Therefore, by designing the shape feature of the centrifugal fan blade 210, i.e., the arc shape between the first side A1 and the second side A2, the airflow loss caused by the linear shape is avoided, and the feature of gradually decreasing height is designed to increase the contact area when the airflow passes through, so as to ensure more airflow to interact with the surface of the fan blade, thereby improving the suction force and efficiency of the airflow. This unique design can effectively capture dust carried in the airflow and improve the dust removal effect.

[0238] In some embodiments, as shown in FIG. 26, in the axial direction of the base 521, the centrifugal fan blade 520 is inclined to the outside of the base 521 by a preset angle a, so as to increase the contact area of the centrifugal fan blade 520 with the airflow while keeping the projection area of the base 521 in the axial direction unchanged.

[0239] Specifically, in order to reduce the weight of the centrifugal fan blade 520, in the axial direction, part of the centrifugal fan blade 520 protrudes out of the base 521, and the centrifugal fan blade 520 is arranged in an outwardly inclined manner, which can reduce the projection area of the base 521, i.e., the volume of the base 521, while ensuring the same flow guide area, thereby reducing the weight of the centrifugal fan blade 520 and the weight of the dust removal equipment 10, so as to facilitate the user to move and use, and improve the user experience.

[0240] In some embodiments, as shown in FIG. 27, at least two reinforcing ribs 523 are arranged on the side of the base 521 away from the centrifugal fan blade 520 in the axial direction of the base 521, and the reinforcing ribs 523 are used to increase the strength of the base 521.

[0241] Specifically, as shown in FIG. 27, eight reinforcing ribs 523 are arranged on the side of the base 521 away from the centrifugal fan blade 520 in the axial direction. The reinforcing ribs 523 disperse and transfer the external force applied to the base 521, improve the overall strength and rigidity of the base 521, and reduce the risk of deformation or damage caused by external force, so as to avoid the deformation of the centrifugal fan blade 520 due to stress under the action of wind pressure, thereby affecting the flow guide effect of the centrifugal fan blade 520 and damaging the fan blade. Moreover, by arranging the reinforcing ribs 523, the use of the material of the base 521 can be optimized, and the overall weight can be reduced without losing strength.

[0242] The technical effect of the above scheme is that, on the one hand, the fan blade assembly is accommodated in the cavity by a hand-held mini shell, which greatly reduces the physical volume of the dust removal equipment, makes the equipment easy to carry, and is suitable for cleaning needs in various occasions, thereby improving the portability and operability of the dust removal equipment; on the other hand, by means of distinguishing from the prior art, the present scheme reasonably designs the shape characteristics of the centrifugal blade, which presents an arc shape between the first side and the second side, avoiding the airflow loss that may be caused by a straight line shape, and at the same time, the design of the gradually decreasing height feature is beneficial to increasing the contact area when the airflow passes through, ensuring that more airflow interacts with the surface of the fan blade, thereby improving the suction force and efficiency of the airflow, and thus improving the dust removal effect and enhancing the cleaning effect of the dust removal equipment.

[0243] Please continue to refer to FIGS. 24 and 25. For the centrifugal fan blade 520 in the above embodiment, the centrifugal fan blade 520 includes a first blade 522b and a second blade 522c; wherein the first blade 522b and the second blade 522c are sequentially and spaced apart in a circumferential array on the base plate 521, and in the direction perpendicular to the axis of the base plate 521, the projection length of the first blade 522b on the base plate 521 is greater than that of the second blade 522c.

[0244] Specifically, in order to further reduce the loss of wind power, the centrifugal fan blade 520 is composed of a first blade 522b and a second blade 522c; wherein the first blade 522b and the second blade 522c are sequentially and spaced apart, and in the direction perpendicular to the axis, the projection length of the first blade 522b on the base plate is greater than that of the second blade 522c.

[0245] Wherein, the grouping design of the centrifugal fan blade 520 can increase the flow area of the centrifugal fan blade 520 while ensuring the space of the centrifugal fan blade 520 and the airflow cutting inlet when the cross-sectional size of the centrifugal fan blade 520 is small, in addition, the grouping design of the centrifugal fan blade 520 can also perform secondary flow distribution on the airflow, so that the airflow is more uniformly dispersed when passing through the centrifugal fan blade 520, and the wind power loss is further reduced.

[0246] In an embodiment, the distance from the first side A1 of the first blade 522b to the axis of the base plate 521 is less than that of the second blade 522c; and the end faces of the first side A1 of the first blade 522b and the first side A1 of the second blade 522c are both circular arcs and are the same circular arcs.

[0247] Specifically, as shown in FIG. 25, the number of the first vanes 522b and the second vanes 522c is 5 respectively, the 5 first vanes 522b and the 5 second vanes 522c are arranged in a circumferential array around the axis respectively, and the first vanes 522b and the second vanes 522c are arranged in sequence and at intervals. In the direction perpendicular to the axis, the projection length of the first vanes 522b on the base plate 521 is greater than the projection length of the second vanes 522c on the base plate 521, the end surface of the first side A1 of the first vanes 522b and the first side A1 of the second vanes 522c are both arc-shaped and are the same circular arc, and the distance from the first side A1 of the first vanes 522b to the axis is less than the distance from the first side A1 of the second vanes 522c to the axis, and in the direction perpendicular to the axis, the distance from the first vanes 522b and the second vanes 522c to the base plate 521 at the same diameter of the base plate 521 is the same.

[0248] In some embodiments, the number and size of the first vanes 522b and the second vanes 522c are designed according to the space layout and the wind loss selected according to the size of the dust removal equipment 10, but in other embodiments, the number of the first vanes 522b and the second vanes 522c can also be 3, 6 or 9, etc. In addition, in order to simplify the structure and facilitate processing, the centrifugal fan blade 520 is composed of the first vanes 522b and the second vanes 522c, and in other embodiments, the centrifugal fan blade 520 can also include a third centrifugal fan blade 520 or a fourth centrifugal fan blade 520, etc., which is not limited here.

[0249] Among them, through the hierarchical and interval arrangement design of the first vanes 522b and the second vanes 522c, the flow direction of the airflow can be more uniform and dispersed when passing through the centrifugal fan blade 210, avoiding the wind loss caused by the airflow converging in a certain position, and the uniform distribution of the airflow enables each area to fully participate in the pushing process of the airflow, further improving the overall wind pressure. Moreover, the distance from the first side A1 of the first vanes 522b to the axis is less than the distance from the first side A1 of the second vanes 522c, so that the first vanes 522b can more effectively guide the airflow into the second vanes 522c under the action of centrifugal force, thereby achieving the purpose of secondary flow distribution.

[0250] Among them, through the secondary flow distribution of the airflow, the airflow is more uniformly distributed, thereby effectively reducing the wind loss and improving the overall performance of the equipment. For example, when the airflow flows uniformly, its kinetic energy can be more fully utilized, avoiding unnecessary energy loss in areas with insufficient pressure. Further, after passing through the carefully designed vane assembly 200, the airflow can be more effectively converged and pushed, thereby driving more dust and impurities into the equipment and improving the cleaning effect.

[0251] In an embodiment, in the axial direction of the base plate 521, the first side A1 of the first and second blades 522b and 522c are each inclined outward of the center of the base plate by a preset angle β1, and the second side A2 of the first and second blades 522b and 522c are each inclined outward of the edge of the base plate by a preset angle β2, so as to increase the contact area of the centrifugal fan blade 520 with the airflow while keeping the projection area of the base plate 521 in the axial direction unchanged.

[0252] In order to reduce the weight of the centrifugal fan blade 520, in the axial direction, the first side A1 of the centrifugal fan blade 520 is designed to deviate from the center of the base plate, and the second side A2 is designed to extend beyond the edge of the base plate, i.e., the centrifugal fan blade 520 is designed as a whole to be inclined outward, so as to reduce the projection area of the base plate 521 while keeping the same flow area, i.e., to reduce the volume of the base plate 521, thereby reducing the weight of the centrifugal fan blade 520 and the weight of the dust removal equipment 10, so as to facilitate the user to move and use, and improve the user experience.

[0253] Specifically, as shown in FIGS. 24 and 28, each first blade 522b and second blade 522c is designed as a whole to deviate from the center of the base plate from the connection to the end of the first side A1 close to the center of the base plate, and is designed as a whole to deviate from the edge of the base plate from the connection to the end of the second side A2 close to the edge of the base plate.

[0254] In the specific implementation process of the above technical solution, the centrifugal fan blade 520 is compact in structure, and the base plate 521 is arranged in the cavity 101 to bear the load and connection function. The centrifugal fan blade 520 is composed of the first blades 522b and the second blades 522c, and the difference between the two types of blades enables them to play a more effective airflow guiding role in different areas. In the axial direction, the first side A1 of the first and second blades 522b and 522c are each inclined outward of the center of the base plate by a preset angle β1, which can effectively guide the airflow to diffuse outward. At the same time, in the second side A2, the first and second blades 522b and 522c are each inclined outward of the edge of the base plate by a preset angle β2, which is to ensure that the airflow can form a larger contact area when passing through the fan blade, thereby improving the overall airflow processing capacity of the fan blade assembly. Importantly, this design keeps the projection area of the base plate 521 in the axial direction unchanged, avoiding the problem of increasing the volume of the equipment due to the increase of the contact area, so that the assembly is still suitable for use in portable dust removal equipment.

[0255] The technical effect of the above scheme is that by designing the first type of blades and the second type of blades with different inclination angles, the contact area with the airflow can be effectively increased while ensuring that the projection area of the chassis remains unchanged, thereby significantly improving the working efficiency of the dust removal equipment. This innovative combination of inclination angles and blade design optimizes the airflow path and improves the processing capacity of the airflow.

[0256] Embodiment Seven

[0257] Modern portable dust removal equipment has higher requirements for the structural design of components, especially in terms of the installation and connection of the wind pressure motor. Traditional designs often lack flexibility, leading to unstable equipment operation and insufficient wind pressure generation. The second installation component proposed in this application has a modular structure, effectively covering and fixing the wind pressure motor, which not only improves the overall performance of the equipment but also ensures functional integration in limited space.

[0258] In one embodiment, as shown in FIG. 3, the portable dust removal equipment 10 further comprises a second installation component 530; wherein the second installation component 530 is arranged in the second shell 120 and fixed in the installation cavity 101a, the second installation component 530 is used to cover and fix the wind pressure motor 510, and an opening is provided on the side of the output shaft 511 of the wind pressure motor 510 close to the dust cavity 101b, so that the centrifugal fan blade 520 is connected to the output shaft 511 of the wind pressure motor 510.

[0259] The second installation component 530 is fixed and covered by the second installation component 530, which can keep the wind pressure motor 510 stable during equipment operation, reduce the instability caused by vibration, and improve the overall operation safety and reliability of the dust removal equipment 10. In addition, the opening design of the second installation component 530 allows the centrifugal fan blade 520 to be directly and quickly connected to the wind pressure motor 510, ensuring efficient generation of wind pressure. This structure can reduce the impedance of airflow flow, improve the wind pressure efficiency of the equipment, and thus improve the dust suction effect.

[0260] Further, referring to FIGS. 39 and 40, the second installation component 530 specifically includes: a mounting seat 531, a mounting cover 532, a connecting element 533, and a mounting cylinder 534, wherein the mounting cover 532 and the mounting seat 531 together enclose the wind pressure motor 510, the connecting element 533 is curved in the axial direction of the second shell 120, the mounting cover 532 is provided with a heat dissipation hole 532b, and the heat dissipation hole 532b is a straight fan-shaped hole.

[0261] Specifically, referring to FIG. 46, the mounting seat 531 is a cylindrical cavity wall structure lacking a top cover, the mounting cover 532 is a cylindrical cavity wall structure lacking a bottom wall, and the mounting seat 531 and the mounting cover 532 are coaxially arranged with the second shell 120, the mounting cover 532 is inserted into the mounting seat 531, and the mounting cover 532 and the mounting seat 531 jointly enclose the wind pressure motor 510. The middle part of the mounting cover 532 is provided with a through hole 532a, and the power shaft 511 of the wind pressure motor 510 is inserted into the through hole 532a to extend out of the mounting cover 532 and be installed with the centrifugal fan blade 520.

[0262] Among them, by jointly enclosing the wind pressure motor 510 through the mounting cover 532 and the mounting seat 531, the motor is stable and fully protected. This structural design effectively resists damage to the motor from the external environment, while providing good support.

[0263] In some embodiments, the connecting element 533 is a rib plate structure, the mounting cylinder body 534 is a circular ring cylindrical shell structure, the connecting element 533 is connected to the inner wall of the mounting cylinder body 534 in the direction perpendicular to the axis of the second shell 120, and the other end is connected to the mounting seat 531 to realize the installation of the wind pressure motor 510 on the second shell 120.

[0264] Further, the connecting element 533 is curved in the axial direction of the second shell 120, that is, the connecting element 533 is in the form of a circular arc, and the number of connecting elements 533 is 5, and the 5 connecting elements 533 are arranged around the mounting seat 531. The curved arrangement of the connecting element 533 can increase the contact area while guiding the gas, thereby reducing the resistance to the airflow.

[0265] Among them, through the curved structural design of the connecting element 533, it is helpful to guide the gas flow to a more smooth path, reducing the resistance of the airflow. This optimized design ensures that the gas flow after passing through the wind pressure motor 510 is more efficient, reducing the risk of airflow convergence and vortex generation, and improving the utilization rate of wind pressure.

[0266] Among them, in order to fit the shape of the wind pressure motor 510 and the installation cavity 101a, the outer contour of the mounting seat 531, the mounting cover 532 and the mounting cylinder body 534 is arranged in the form of a cylinder, which can optimize the space and keep the distance between the mounting cylinder body 534 and the inner wall of the second shell 120 consistent, avoiding uneven wind pressure and causing resistance. In other embodiments, the wind pressure motor 510 can also be fixedly installed on the second shell 120 in other structures to realize the fixed installation of the wind pressure motor 510.

[0267] In some embodiments, the connecting element 533 can be a flat plate structure or a block structure with a large cross-sectional area, and the two ends of the connecting element 533 are connected to the second shell 120 and the mounting seat 531 respectively to fix the mounting seat 531 on the second shell 120. In other embodiments, the number of connecting elements 533 can also be 2, 3, or 6 or more, and the plurality of connecting elements 533 are arranged around the mounting seat 531, or the number of connecting elements 533 is directly set to one while ensuring the mounting strength of the mounting seat 531.

[0268] In order to simplify the structure of the second shell 120 and reduce the production difficulty of the second shell 120, the mounting unit 530 can be an independent component, and the wind pressure motor 510 is installed on the mounting unit 530 and then installed on the second shell 120 together, but in other embodiments, the mounting unit 530 can also be integrally formed with the second shell 120, which is not limited here.

[0269] In some embodiments, as shown in FIG. 45, the mounting cover 532 is provided with four heat dissipation holes 532b, and the heat dissipation holes 532b are overall in the shape of a right-angle sector. The four heat dissipation holes 532b are uniformly distributed on the mounting cover 532, so that the mounting cover 532 is overall in a hollow structure. The arrangement of the heat dissipation holes 532b is beneficial to heat dissipation of the wind pressure motor 510, which can reduce the influence of the power or damage of the wind pressure motor 510 caused by overheating due to continuous operation, thereby improving the service life of the dust removal equipment 10. In other embodiments, the heat dissipation holes 532b can also be in different shapes such as ellipse, circle or polygon, or the mounting cover 532 can be directly provided in a porous grid structure, and the number and shape of the heat dissipation holes 532b are not limited here.

[0270] The heat dissipation holes 532b are provided on the mounting cover 532, and the heat dissipation holes 532b are overall in the shape of a right-angle sector to facilitate smooth dissipation of heat generated by the wind pressure motor 510 during operation. This heat dissipation design can effectively avoid motor overheating, thereby improving the working efficiency and service life of the motor.

[0271] The technical effect of the present embodiment is that the modular wind pressure assembly simplifies the structure and improves the assembly efficiency by tightly combining the wind pressure motor and the centrifugal fan blade. At the same time, the strong wind pressure makes the flow of wind more stable, ensuring the maximization of the cleaning effect. During use, the user can complete the cleaning of various surfaces in a short time through the strong wind pressure, thereby improving the use satisfaction.

[0272] In the prior art, the airflow passage design of dust removal equipment often hinders the flow of airflow, especially from the cavity to the air outlet, the airflow is easily disturbed by internal components. Therefore, an effective guide component is needed to enable smooth airflow when inhaling, reduce the resistance of internal components of the equipment, and thus improve the flow capacity of the airflow.

[0273] In an embodiment, the connecting element 533 in the second mounting assembly 530 is an arc-shaped airflow vane; wherein the two sides of the airflow vane are fixed to the circumferential surface of the mounting seat 531 and the inner wall of the mounting cylinder 534 respectively in a preset inclined angle, so as to guide the airflow in a preset inclined angle when the airflow carrying dust particles is sucked into the cavity 101 from the dust suction port 102.

[0274] Specifically, as shown in FIG. 29, the overall shape of the airflow vane is arc-shaped, i.e. forming a streamlined design, which helps the airflow to flow smoothly along the preset path. Therefore, the arc-shaped structure can effectively reduce the vortex generated when the airflow turns, reduce the resistance and energy loss of the airflow.

[0275] Further, the two sides of the airflow vane are fixed to the circumferential surface of the mounting seat 531 and the inner wall of the mounting cylinder 534 respectively according to a preset inclined angle (such as 30°, 45°, 60°, etc.). The design of this inclined angle ensures that the airflow can flow in a specific direction under the guidance of the vane when being sucked in, thereby increasing the contact area of the airflow with the suction gas and improving the dust removal effect.

[0276] Further, the airflow vane can be stably fixed between the mounting seat 531 and the mounting cylinder 534 by suitable fixing methods (such as screws, adhesion or buckling), so as to ensure that the vane does not displace or fall off during use, thereby ensuring the effectiveness and stability of its function.

[0277] In an embodiment, the outer profiles of the mounting seat 531 and the mounting cover 532 are arranged in a cylindrical manner, and a plurality of airflow vanes are arranged in a circumferential array on the circumferential surface of the mounting seat 531 to provide force support to the mounting seat 531.

[0278] Specifically, referring to FIG. 34, the connecting element 533 is curved in the axial direction of the second housing 120, i.e. the connecting element 533 is in the shape of a circular arc, and the number of the connecting element 533 is 11. The 11 connecting elements 533 are arranged around the circumferential outer profile of the mounting seat 531, and each connecting element 533 is arranged in a circular arc shape, which can increase the contact area while guiding the gas to reduce the resistance to the airflow.

[0279] In some embodiments, the connecting element 533 can be a flat plate structure or a block structure with a large cross-sectional area, and the two ends of the connecting element 533 are connected to the mounting cylinder 534 and the mounting seat 531, respectively, to fix the mounting seat 531 in the mounting cylinder 534. In other embodiments, the number of connecting elements 533 can also be 2, 3, or 6 or more, and the plurality of connecting elements 533 are arranged around the mounting seat 531, or the number of connecting elements 533 is directly set to one while ensuring the installation strength of the mounting seat 531.

[0280] In order to fit the shape of the wind pressure motor 510 and the mounting cavity 101b, the outer contours of the mounting cavity 101b, the mounting seat 531, and the mounting cylinder 534 are arranged in a cylindrical manner to optimize the space and keep the distance between the mounting cylinder 534 and the inner wall of the second shell 120 consistent, avoiding uneven wind pressure and causing resistance. In other embodiments, the wind pressure motor 510 can also be fixedly installed on the second shell 120 in other structures to achieve the fixed installation of the wind pressure motor 510.

[0281] In an embodiment, the wind pressure motor 510 is installed by the mounting seat 531 and the mounting cover 532, and then the connecting element 533 is connected to the circumferential surface of the mounting seat 531 and the inner wall of the mounting cylinder 534 in the axial direction of the second shell 120 at a predetermined inclination angle, and finally the mounting cylinder 534 is fitted to the second shell 120 to enclose the entire wind pressure motor 510, to achieve the installation of the wind pressure motor 510 in the cavity 101.

[0282] The above-mentioned embodiments have the beneficial effect that by designing the connecting element as an arc-shaped air guide vane, the deficiencies of traditional dust removal equipment in air flow guidance are effectively solved. The inclined design of the air guide vane not only smoothly guides the air flow, but also captures more dust particles in the air flow, thereby improving the working efficiency and performance of the dust removal equipment.

[0283] In an embodiment, a through hole 532a is provided in the central region of the mounting cover 532 near the dust suction port 102, and the through hole 532a is used for the output shaft 511 of the wind pressure motor 510 to extend out, so that the centrifugal fan blade 520 can be sleeved on the end of the output shaft 511.

[0284] Specifically, as shown in FIG. 30, the mounting cover 532 is a cylindrical structure, and the mounting cover 532 is provided with a through hole 532a near the centrifugal fan blade 520, and the through hole 532a is used for sleeving and fixing the output shaft 511 of the wind pressure motor 510, so that the mounting cover 532 is driven to rotate synchronously when the output shaft 511 rotates.

[0285] In current motor designs, the structure of the mounting cover 532 often affects the overall performance of the motor. If the mounting cover 532 cannot be effectively connected to the output shaft 511 of the motor, it will lead to reduced transmission efficiency and increased wear of components. Therefore, the mounting cover 532 in this application has a cylindrical structure and a through hole 532a is provided at the connection with the output shaft 511 to achieve a good connection between the output shaft 511 and the mounting cover 532, ensuring that the rotation of the output shaft 511 can synchronously drive the rotation of the mounting cover 532.

[0286] Specifically, the mounting cover 532 has a cylindrical structure, and a through hole 532a is provided on the side near the centrifugal fan blade 520. This through hole 532a is used to connect and fix the output shaft 511 of the wind turbine motor 510, so that the mounting cover 532 rotates synchronously when the output shaft 511 rotates. The cylindrical design of the mounting cover 532 provides structural stability, and the through hole 532a not only simplifies the installation process of the output shaft but also ensures that the mounting cover 532 can effectively rotate synchronously when the output shaft 511 rotates, thereby avoiding energy loss and wear caused by sliding friction between components.

[0287] The above design enhances the driving effect of the wind turbine motor 510, especially under high speed and high load operating conditions, ensuring effective cooperation between the mounting cover 532 and the centrifugal fan blade 520, improving the overall performance and efficiency of the wind turbine motor 510. At the same time, the cylindrical mounting cover 532 not only provides mechanical and electromagnetic protection in the wind turbine motor, but also plays an important role in thermal management, grounding and stability, ensuring the safe and effective operation of the motor in various working environments.

[0288] In some embodiments, the mounting cover 532 is a cylindrical cavity wall structure without a bottom wall, and both the mounting cover 532 and the mounting base 531 are coaxially arranged with the second housing 120. The mounting cover 532 is inserted into the mounting base 531, and the mounting cover 532 and the mounting base 531 together enclose and mount the wind turbine motor 510. A through hole 532a is provided in the middle of the mounting cover 532, and the output shaft 511 of the wind turbine motor 510 is inserted into the through hole 532a and extends out of the mounting cover 532 to be mounted with the centrifugal fan blade 520.

[0289] The technical advantage of the above embodiment is that by using the mounting cover and mounting base to enclose and install the wind turbine motor, the motor is ensured to be stable and fully protected. This structural design effectively resists damage to the motor from the external environment and provides good support.

[0290] In one embodiment, the mounting cover 532 is hollow in general, and a heat dissipation hole 532b is provided on the side of the mounting cover 532 near the dust suction port 102. The heat dissipation hole 532b is used to dissipate heat when the wind pressure motor 510 is running.

[0291] In some embodiments, as shown in FIG. 30, the mounting cover 532 is provided with four heat dissipation holes 532b, and each heat dissipation hole 532b is a straight sector as a whole. The four heat dissipation holes 532b are uniformly distributed on the mounting cover 532, so that the mounting cover 532 has a hollow structure as a whole. The arrangement of the heat dissipation holes 532b is conducive to heat dissipation of the air pressure motor 510, which can reduce the influence of the overheating of the air pressure motor 510 caused by continuous operation on the power or damage, thereby improving the service life of the dust removal equipment 10. In other embodiments, the heat dissipation holes 532b can also be different shapes such as ellipses, circles or polygons, or the mounting cover 532 can be directly provided with a porous grid structure, and the number and shape of the heat dissipation holes 532b are not specifically limited here.

[0292] In some embodiments, as shown in FIG. 30, the mounting cover 532 is provided with four heat dissipation holes 532b, and each heat dissipation hole 532b is a straight sector as a whole. The four heat dissipation holes 532b are uniformly distributed on the mounting cover 532, so that the mounting cover 532 has a hollow structure as a whole. The arrangement of the heat dissipation holes 532b is conducive to heat dissipation of the air pressure motor 510, which can reduce the influence of the overheating of the air pressure motor 510 caused by continuous operation on the power or damage, thereby improving the service life of the dust removal equipment 10. In other embodiments, the heat dissipation holes 532b can also be different shapes such as ellipses, circles or polygons, or the mounting cover 532 can be directly provided with a porous grid structure, and the number and shape of the heat dissipation holes 532b are not specifically limited here.

[0293] The technical effects of the above embodiments are that the modular mounting assembly tightly combines the air pressure motor and the centrifugal fan blade together, simplifies the structure, and improves the assembly efficiency. At the same time, the strong air pressure makes the flow of air more stable, ensuring the maximization of the cleaning effect.

[0294] In an embodiment, a rubber pad 535 is arranged on the outer surface of the mounting cylinder 534, which is used to fit the inner wall of the cavity 101 to reduce the vibration intensity transmitted from the mounting cylinder 534 to the shell 100 when the air pressure motor 510 is running.

[0295] Specifically, as shown in FIG. 33, since the air pressure motor 510 is installed in the cavity 101 by the second mounting assembly 530, the vibration caused by the movement of the air pressure motor 510 is transmitted to the shell 100 through the mounting cylinder 534 when the air pressure motor 510 is working, thereby reducing the user experience. Therefore, a rubber pad 535 is arranged on the outer surface of the mounting cylinder 534 to reduce the vibration intensity transmitted from the mounting cylinder 534 to the shell 100 when the air pressure motor 510 is running.

[0296] In some embodiments, the rubber pad 535 can be made of high-elastic and wear-resistant rubber material, which can effectively absorb vibration energy and achieve the best shock isolation effect. The elastic property of the rubber material makes it deform when subjected to vibration, thereby reducing the intensity of the impact force transmitted outward.

[0297] In some embodiments, the outer surface of the rubber pad 535 is regularly shaped, which can closely fit the inner wall of the cavity 101, ensuring that the vibration energy can be fully absorbed by the rubber pad during the operation of the wind pressure motor 510, and the shell 100 is maximally protected from vibration. Through such a fitting design, the rubber pad 535 can maintain stable contact under different working conditions, ensuring the persistence of its effect.

[0298] The above-mentioned embodiments have the beneficial effect that the vibration generated when the wind pressure motor 510 starts and operates will be absorbed by the rubber pad 535 through the installation cylinder 534, effectively reducing the transmission of vibration. This not only can reduce the overall noise level of the equipment, but also can improve the stability of the equipment, thereby improving the working experience of the user and the service life of the equipment.

[0299] In an embodiment, as shown in FIG. 32, the installation cylinder 534 is a cylinder structure as a whole, and an airflow channel is formed in the inner wall of the cylinder of the installation cylinder 534, and a dust collecting sheet 536 is arranged on the inner wall of the cylinder, which is used to adsorb the dust particles carried by the airflow flowing in the airflow channel.

[0300] Specifically, the installation cylinder 534 is a cylinder structure, designed as a closed cylinder, which can effectively surround the wind pressure motor 510 and the centrifugal blade 400, thereby maintaining the stability of the assembly and providing an airflow channel for the airflow. An airflow channel is formed in the inner wall of the cylinder of the installation cylinder 534, which is designed to ensure that the airflow can pass through efficiently, promoting the airflow processing performance of the wind pressure motor 510 and the centrifugal blade 400, thereby improving the working efficiency of the entire dust removal equipment 10.

[0301] Among them, the dust collecting sheet 536 is arranged on the inner wall of the cylinder, and the dust collecting sheet 536 is used to adsorb the dust particles carried by the airflow flowing in the airflow channel. The surface of the dust collecting sheet 536 can be designed with special materials or coatings to improve its adsorption capacity for dust particles, ensuring that dust can be effectively captured when the airflow passes through, and improving the cleanliness of the airflow.

[0302] Further, a handle portion 537 can be arranged on the installation cylinder 534 for a user to install or dismount the second installation assembly 530 from the shell 100.

[0303] Specifically, as shown in FIG. 32, the mounting cylinder 534 is provided with a handle part 537 on the side away from the dust suction port 102 in the airflow direction. The handle part 537 is a hook-shaped structure integrally formed with the mounting cylinder 534. The handle part 537 facilitates the user to take out the second mounting assembly 530 from the first shell 110 when the first shell 110 and the second shell 120 are disassembled, thereby improving the user experience. It should be noted that in the embodiments of the present application, the handle part 537 is provided on the mounting cylinder 534 in order to increase the volume of the handle part 537 and improve the user experience of holding. However, in some embodiments of the present application, the handle part 537 can also be provided on other components, such as the filter module, the air pressure motor 510, etc.

[0304] The technical effect of the above embodiments is that the design of the mounting cylinder of the cylinder structure can perfectly surround the air pressure motor and the centrifugal blades, forming a closed space to guide the airflow. The design of the airflow channel ensures that the airflow flows along the predetermined path, which can promote the concentration and acceleration of the airflow. The setting of the dust collection sheet greatly improves the collection efficiency of dust particles, which significantly improves the dust removal effect and enables the user to obtain fresher air.

[0305] In an embodiment, as shown in FIG. 35, the air pressure motor 510 includes a metal support 512, a bearing set 513, a rotor set 514, and a stator set 515. The metal support 512 is fixed in the second mounting assembly 530 and has a truncated cone structure for covering and fixing the bearing set 513. The bearing set 513 is accommodated in the metal support 512. The shaft in the bearing set 513 is used to support the rotor set 514 and allow the rotor set 514 to rotate through the shaft. The rotor set 514 includes the output shaft 511 of the air pressure motor 510, and the output shaft 511 is connected to the shaft of the bearing set 513. The stator set 515 is sleeved on the peripheral surface of the metal support 512. When current passes through the stator set 515, the stator set 515 generates a rotating magnetic field to drive the output shaft 511 to rotate.

[0306] Specifically, the traditional motor has certain limitations in structural design and operating performance, which can easily lead to problems such as high noise, high heat, low efficiency, etc. Therefore, in order to meet the actual needs, a wind pressure motor 510 with an improved structure is provided in this application. Among them, the metal support 512 of the wind pressure motor 510 is a truncated cone structure, which is suitable for covering and fixing the main components in design, ensuring the stable connection and support of each part. The bearing kit 513 of the wind pressure motor 510 is housed in the metal support 512, which can effectively reduce the friction between rotating parts, improve operating efficiency, and the rotating shaft in the bearing kit 513 serves to support the rotor kit 514 and allow the rotor kit 514 to rotate smoothly. The rotor kit 514 of the wind pressure motor 510 includes the output shaft 511 of the wind pressure motor 510, which is connected to the rotating shaft in the bearing kit 513, forming the core part of mechanical power transmission. The stator kit 515 of the wind pressure motor 510 is fixed on the circumferential surface of the metal support 512, so that when current passes through the stator kit 515, a rotating magnetic field is generated, thereby driving the output shaft 511 to rotate, playing a key role in the operation of the motor.

[0307] In other embodiments, please continue as shown in Figure 35, the wind pressure motor 510 can also include a motor drive board 516. Among them, the motor drive board 516, also known as motor control board or drive circuit board, is a key electronic component for controlling and driving the operation of the motor. Its main functions include: ① Motor control, the motor drive board can adjust the working state of the motor, control the start, stop, speed and direction of the motor, etc. ② Power management, the board is usually responsible for converting the input power (such as from the battery or power adapter) into voltage and current suitable for the motor. ③ Signal processing, the drive board can receive signals from the user interface (such as switches, remote controls, etc.), and adjust the working state of the motor according to these signals. ④ Protection function, the motor drive board 516 usually has functions such as overload protection, overheat protection and short circuit protection to ensure the safety of the motor and the entire system. ⑤ Feedback system, the drive board is also equipped with sensors that can monitor the operating state of the motor (such as speed, temperature, etc.), and dynamically adjust according to the feedback information.

[0308] In an embodiment, please continue as shown in Figure 35, the rotor kit 514 also includes a magnetic ring 5141 and a metal shell 5142; among them, the magnetic ring 5141 is wrapped around the stator kit 515, used to concentrate and enhance the magnetic field strength generated by the stator kit 515, to ensure the magnetic flux density of the wind pressure motor 510; the metal shell 5142 is wrapped around the magnetic ring 5141, used to electromagnetically shield the magnetic ring 5141, to ensure the electrical stability performance of the wind pressure motor 510.

[0309] In traditional motors, the magnetic field between the rotor and the stator is relatively dispersed, making it difficult to fully utilize the magnetic field generated by the stator, resulting in reduced motor efficiency. In addition, external electromagnetic interference can negatively affect the stability of the motor. Therefore, in practical applications, the design of the rotor assembly 514 can effectively reduce external electromagnetic interference and improve the overall performance of the motor. For example, in high-load working conditions, the stability of the motor is enhanced, which helps to prolong the service life of the motor.

[0310] In some embodiments, in the wind pressure motor 510, the stator assembly 515 is covered by a magnetic ring 5141, which mainly includes the following functions: ① Enhance the magnetic field strength, the use of the magnetic ring 5141 can concentrate and enhance the magnetic field generated by the stator, thereby improving the magnetic flux density of the motor, which helps to improve the efficiency and output power of the motor. ② Reduce the magnetic flux loss, the magnetic ring 5141 can reduce the leakage of magnetic flux in the air gap, while optimizing the magnetic circuit design, thereby reducing the magnetic flux loss of the motor, which is of great significance to improve the operating efficiency of the motor. ③ Improve the performance of the motor, the magnetic ring 5141 can improve the starting torque and acceleration performance of the motor by enhancing the magnetic field of the stator, ensuring that the motor can quickly respond when the load changes, and improving the stability of the motor performance. ④ Reduce noise and vibration, the magnetic ring 5141 can improve the magnetic field distribution of the motor, reduce electromagnetic noise and vibration, and improve the smooth running characteristics of the motor, improving the comfort of use. ⑤ Improve durability, the magnetic ring 5141 wrapped on the stator is usually made of high-performance magnetic materials, which can resist mechanical and thermal stress during the operation of the motor, thereby improving the durability and service life of the motor. ⑥ Optimize the temperature control characteristics, the material selection of the magnetic ring 5141 can help optimize the thermal management performance of the motor, improve the heat dissipation efficiency, and help reduce the temperature rise during the operation of the motor, protecting the motor from overheating damage.

[0311] In some embodiments, in the wind pressure motor 510, the metal shell 5142 is used to cover the magnetic ring 5141, which has the following functions: ①Mechanical protection, the metal shell 5142 provides structural support and protection for the internal magnetic ring 5141 and other components, preventing mechanical damage, collision or environmental factors (such as water, dust, chemicals, etc.) from affecting the internal components of the motor. ②Electromagnetic shielding, the metal shell 5142 can effectively block electromagnetic interference (EMI), preventing the electromagnetic radiation generated by the motor from affecting external devices or other circuits, ensuring the normal operation of the motor and the electrical safety of the surrounding environment. ③Heat management, the metal material of the metal shell 5142 has good thermal conductivity, which can help dissipate the heat generated by the stator and the magnetic ring 5141 during operation, improving the heat dissipation efficiency of the motor and preventing overheating. ④Provide grounding, the metal shell 5142 can usually serve as the grounding element of the motor, providing additional protection for safe operation, preventing static accumulation or electrical leakage and other safety hazards. ⑤Improve magnetic field stability, the metal material of the metal shell 5142 can optimize the distribution of the internal magnetic field through magnetic shielding, ensuring that the performance of the motor is more stable, while reducing interference caused by external magnetic field changes. ⑥Strengthen the structural strength, the metal shell 5142 provides the necessary structural strength for the motor, enabling it to withstand vibrations, impacts and other mechanical stresses during operation, extending the service life of the motor. ⑦Aesthetics and maintainability, the appearance design of the metal shell 5142 can make the motor more aesthetically pleasing, while also facilitating later maintenance and inspection, improving the serviceability of the motor.

[0312] In some embodiments, the magnetic ring 5141 can be made of high permeability material, such as Rb-Fe-B, rubber strip, knotless magnet, and other ferrite materials, etc., thereby providing good magnetic flux concentration effect. The metal shell 5142 can be made of aluminum or other conductive metal materials, which provides shielding while maintaining lightweight design.

[0313] In an embodiment, as shown in FIGS. 32 and 33, the metal shell 5142 is a cylindrical structure, and the metal shell 5142 is provided with a second opening 510b near the side of the centrifugal fan blade 520, which is used to sleeve and fix the output shaft 511 of the wind pressure motor 510, so as to drive the metal shell 5142 to rotate synchronously when the output shaft 511 rotates.

[0314] In the current motor design, the structure of the metal shell 5142 often affects the overall performance of the motor. If the metal shell 5142 cannot be effectively connected with the output shaft of the motor, it will result in reduced transmission efficiency and accelerated component wear. Therefore, the metal shell 5142 in the present application has a cylindrical structure, and a second opening 510b is provided at the output shaft 511 connection to achieve good connection between the output shaft 511 and the metal shell 5142, ensuring that the output shaft 511 can drive the metal shell 5142 to rotate synchronously when rotating.

[0315] Specifically, the metal shell 5142 is a cylindrical structure, and the metal shell 5142 is provided with a second opening 510b near the centrifugal fan blade 520 side, which is used to sleeve and fix the output shaft 511 of the air pressure motor 510, so that the metal shell 5142 can be driven to rotate synchronously when the output shaft 511 rotates. Since the metal shell 5142 adopts a cylindrical design, it provides structural stability, and the design of the second opening 510b not only simplifies the installation process of the output shaft, but also ensures that the metal shell 5142 can effectively rotate synchronously when the output shaft 511 rotates, thereby avoiding energy loss and wear caused by sliding friction between components. The above design can enhance the driving effect of the air pressure motor 510, especially under high speed and high load working conditions, to ensure effective cooperation between the metal shell 5142 and the centrifugal fan blade 520, improve the overall performance and efficiency of the air pressure motor 510, and at the same time, the cylindrical metal shell 5142 not only provides mechanical and electromagnetic protection in the air pressure motor, but also plays an important role in heat management, grounding and stability, ensuring the safe and effective operation of the motor in various working environments.

[0316] In some embodiments, the metal shell 5142 is a cylindrical cavity wall structure without a bottom wall, and the metal shell 5142 and the mounting seat 221 are coaxially arranged with the second shell 120. The metal shell 5142 is inserted into the mounting seat 221, and the metal shell 5142 and the mounting seat 221 jointly enclose the air pressure motor 510, and a first opening 510a is provided in the middle of the metal shell 5142, and the output 211 of the air pressure motor 510 is inserted into the first opening 510a to extend out of the metal shell 5142 and install the centrifugal fan blade 520.

[0317] The technical effect of the above embodiment is that the metal shell 5142 and the mounting seat 221 jointly enclose the air pressure motor 510, ensuring that the motor is stable and well protected, and this structural design effectively resists damage to the motor from the external environment, while providing good support.

[0318] In some embodiments, as shown in FIG. 33, the metal shell 5142 is provided with heat dissipation holes 532b, which are in the shape of a straight fan. As shown in FIG. 33, the metal shell 5142 is provided with four heat dissipation holes 532b, which are in the shape of a straight fan and are evenly distributed on the metal shell 5142, so that the metal shell 5142 has a hollow structure. The arrangement of the heat dissipation holes 532b is conducive to heat dissipation of the wind pressure motor 510, which can reduce the overheating of the wind pressure motor 510 caused by continuous operation, thereby improving the service life of the dust removal equipment 10. In other embodiments, the heat dissipation holes 532b can also be in different shapes such as an ellipse, a circle or a polygon, or the metal shell 5142 can be directly provided in a porous grid structure. The number and shape of the heat dissipation holes 532b are not limited here.

[0319] By providing the metal shell 5142 with heat dissipation holes 532b, which are in the shape of a straight fan, the heat generated by the wind pressure motor 510 during operation can be smoothly dissipated. This heat dissipation design can effectively prevent the motor from overheating, thereby improving the working efficiency and service life of the motor.

[0320] The technical effect of the above embodiments is that the modular wind pressure assembly combines the wind pressure motor and the centrifugal fan blade together, simplifying the structure and improving the assembly efficiency. At the same time, the strong wind pressure makes the flow of wind more stable, ensuring the maximization of the cleaning effect. During use, the user can complete the cleaning of various surfaces in a short time through the strong wind pressure, thereby improving the user's satisfaction.

[0321] In an embodiment, as shown in FIG. 35, the bearing set 513 includes a first bearing 5131 and a second bearing 5132. The outer ring of the first bearing 5131 is fixed to the inner wall of the metal support 2132 close to the centrifugal fan blade 520, and the inner ring of the first bearing 5131 is sleeved on the output shaft 511 of the wind pressure motor 510. The outer ring of the second bearing 5132 is fixed to the inner wall of the metal support 2132 away from the centrifugal fan blade 520, and the inner ring of the second bearing 5132 is sleeved on the output shaft 511 of the wind pressure motor 510.

[0322] Specifically, in the design of the wind pressure motor 510, the performance of the bearing directly affects the working efficiency and service life of the motor. Traditional bearing designs often cannot guarantee good axial and radial support under high load and high speed, which leads to increased vibration, noise and wear of the motor. Therefore, by combining the first bearing 5131 and the second bearing 5132 in the bearing set 513, effective support can be provided at different positions to ensure smooth operation of the output shaft 511.

[0323] The first bearing 5131 is installed near the centrifugal fan blade 520, which can withstand the centrifugal force and the larger radial load caused by power transmission; while the second bearing 5132 is located away from the centrifugal fan blade 520, responsible for supporting the other end of the output shaft 511, providing axial stability. The support structure of the two ends effectively disperses the stress generated by the operation of the wind pressure motor 510, thereby reducing wear caused by vibration and load changes.

[0324] In some embodiments, the design of the bearing set 513 also focuses on the selection of bearing materials, and high wear-resistant, low-friction materials such as ceramics or high-performance synthetic materials can be preferred to further improve the working efficiency and durability of the motor. In addition, the sealing design of the bearing can effectively prevent the entry of dust and other contaminants, prolonging the service life.

[0325] In some embodiments, the inner ring diameter of the first bearing 5131 and the second bearing 5132 is the same as the diameter of the output shaft 511, and the outer ring diameter of the first bearing 5131 is smaller than the outer ring diameter of the second bearing 5132.

[0326] Specifically, the first bearing 5131 and the second bearing 5132 are both rotors in the bearing assembly 212, both of which are sleeved on the output shaft 511 of the wind pressure motor 510 and rotate synchronously to drive the output shaft 511 to rotate, thereby driving the centrifugal fan blade 520 to rotate to generate wind pressure in the cavity 101.

[0327] The outer ring diameter of the first bearing 5131 is smaller than that of the second bearing 5132, i.e., the first bearing 5131 is a small bearing, and the second bearing 5132 is a large bearing. In the wind pressure motor 510, the use of the large and small bearings to fix the drive shaft 210a has several purposes: ① load distribution, the combination of large and small bearings can effectively distribute the load acting on the drive shaft 210a, which reduces the pressure on a single bearing and reduces the risk of bearing wear and failure. ② Prevent axial displacement, i.e., two bearings of different sizes can better limit the movement of the drive shaft 210a in the axial and radial directions, ensuring that the motor remains stable during operation and reducing vibration. ③ Enhance load capacity, the large bearing generally has higher load capacity and can bear more axial and radial load, while the small bearing can handle lighter load, which can enhance the load capacity of the entire drive system and adapt to different working conditions. ④ Reduce friction and loss, bearings of different specifications can provide appropriate support according to the characteristics of the movement, helping the drive shaft to obtain more flexible and stable rotation, thereby reducing energy loss and improving motor efficiency. ⑤ Enhance heat management, the size difference of different bearings can help improve the circulation of internal air or lubricating oil, thereby enhancing the heat dissipation capacity of the motor and the bearing, which helps to prevent overheating and prolong the service life. ⑥ Save space and materials, by reasonably matching bearings of different sizes, space and material costs can be saved within a certain range, while meeting the performance requirements of the motor and the flexibility of the structural design.

[0328] In an embodiment, as shown in FIG. 35, the bearing set 513 further includes a pre-press spring 5133, wherein one end of the pre-press spring 5133 is fixed to the inner ring of the first bearing 5131, and the other end is fixed to the second opening 510b of the metal shell 5142. The pre-press spring 5133 is used to provide pre-press force to the first bearing 5131 when the first bearing 5131 drives the output shaft 511 to rotate.

[0329] Specifically, in traditional motor design, the performance of the bearing lies in bearing the vibration and load of the rotating shaft. However, during operation, due to the friction between the bearing and the output shaft, the stability of the bearing may be lost, especially in high-speed and variable load working environment, the stability of the bearing is particularly important. Therefore, the bearing set 513 integrated with the pre-press spring 5133 in the present application can further enhance the working performance and reliability of the wind pressure motor 510, thereby prolonging the service life of the motor.

[0330] In a preferred embodiment of the invention, the preload spring 5133 is connected at one end to the inner ring of the first bearing 5131, and at the other end is fixed to the second opening 510b of the metal housing 5142. This design ensures that when the output shaft 511 of the wind turbine motor 510 rotates, the preload spring 5133 can continuously apply preload to the first bearing 5131, thereby maintaining good contact between the bearing and the output shaft 511, improving the friction of the contact surface, and thus enhancing the overall drive efficiency.

[0331] In some embodiments, the design of the preload spring 5133 allows for automatic adjustment of the applied preload under different operating conditions to adapt to changes in bearing load, preventing slippage due to insufficient load and bearing damage due to excessive load. Furthermore, the preload spring 5133 used in this invention can be made of a highly elastic material to enhance its elasticity and durability, ensuring that it does not lose its preload effect during prolonged operation.

[0332] The preload spring 5133 used in bearings is a specially designed spring primarily used to provide preload between bearings. This preload improves bearing performance and lifespan, ensuring stability and accuracy during operation. Specifically, the main functions of the preload spring 5133 include: ① Reducing clearance: By applying a certain preload force to the bearing, it reduces clearance caused by bearing wear or thermal expansion, thereby improving bearing rigidity and stability. ② Improving load distribution: The preload of the preload spring 5133 helps the bearing distribute the load more evenly, reducing the impact of off-center or uneven loads on the bearing. ③ Enhancing vibration resistance: The preload spring 5133 helps reduce bearing vibration and noise during operation, making the equipment smoother. ④ Extending service life: By maintaining appropriate working clearance and reducing wear, the preload spring 5133 helps extend the service life of the bearing.

[0333] In some embodiments, the preload spring 5133 may be a compression spring, a tension spring, or a torque spring, etc. This application does not make specific limitations, and it may be determined according to the specific bearing application and design requirements.

[0334] In one embodiment, as shown in FIG35, the output shaft 511 has an annular groove (not shown) at the end away from the centrifugal fan blade 520, and the bearing assembly 513 further includes an annular retaining ring 5134; wherein, the annular retaining ring 5134 is engaged in the annular groove and fixed to the inner ring of the second bearing 5132, and the annular retaining ring 5134 is used to limit the relative displacement between the second bearing 5132 and the output shaft 511 when the second bearing 5132 drives the output shaft 511 to rotate.

[0335] Specifically, in the design of the wind pressure motor 510, the function of the output shaft 511 is crucial, which must be able to stably and efficiently transmit power. However, in the working state of high speed or high load, relative displacement may occur between the output shaft 511 and the bearing, causing the failure or damage of the bearing, and thus affecting the overall performance of the wind pressure motor. In order to solve this problem, the present application combines the structural design of the annular clamping groove and the annular clamping ring 5134 to improve the stability between the output shaft 511 and the bearing in the wind pressure motor 510, thereby improving the reliability and working efficiency of the motor.

[0336] Among them, the design of the annular clamping groove is located at the end of the output shaft 511, forming an inner concave annular structure to accommodate the annular clamping ring 5134. When the output shaft 511 is connected to the second bearing 5132, the annular clamping ring 5134 is clamped into the annular clamping groove, thereby fixing the annular clamping ring 5134 on the output shaft. The outer diameter of the annular clamping ring 5134 tightly fits with the inner ring of the second bearing 5132, forming a stable connection.

[0337] Embodiment eight

[0338] In a portable dust removal device, the design of the cavity and its sealing performance directly affect the cleaning efficiency and user experience of the device. Traditional portable dust removal devices usually lack effective sealing mechanisms, resulting in uneven wind pressure or dust leakage during operation, thereby affecting the dust removal effect and the effectiveness of the device. Therefore, developing a more reasonable cavity sealing structure can improve wind pressure control and significantly improve the performance of portable dust removal devices, which has important practical significance.

[0339] Please refer to FIG. 36, FIG. 37 and FIG. 38, the first shell 110 further comprises a mounting column 111 and a connecting rib 112, the connecting rib 112 connects the mounting column 111 and the inner wall of the first shell 110 respectively; and the portable dust removal device 10 further comprises a dust blocking sheet 700, the dust blocking sheet 700 is annular and sleeved on the mounting column 111, wherein the dust blocking sheet 700 is used to close or open the cavity 101 under the action of wind pressure.

[0340] Among them, the mounting column 111 is a cylindrical annular structure, the number of connecting ribs 112 is multiple (such as 3), the multiple connecting ribs 112 are circumferentially arrayed around the axis of the first shell 110, the connecting ribs 112 connect the mounting column 111 and the inner wall of the first shell 110 respectively, and the output shaft 310 of the driving source 300 and the cleaning accessory 200 penetrate the mounting column 111.

[0341] The dust blocking sheet 700 is annular and made of sponge, and comprises a mounting end 710, a rotating end 720 and a rotating shaft part 730. The mounting end 710 is sleeved on the mounting column 111, and the rotating end 720 rotates under the action of wind pressure, thereby changing the shielding degree of the cavity 101 to close or open the cavity.

[0342] In other embodiments, the dust blocking sheet 700 is only an annular sheet which is easy to deform, and is sleeved on the mounting column 111. Thus, the dust blocking sheet 700 is bent to a corresponding degree to change the shielding degree of the cavity 101 under the wind pressure in the cavity 101, thereby opening the cavity to a certain degree to enable the air carrying impurities to be sucked into the cavity 101; and the dust blocking sheet 700 returns to the original sheet shape to change the shielding degree of the cavity 101 under the condition that the wind pressure in the cavity 101 stops, thereby closing the cavity to a certain degree to prevent the impurities in the cavity 101 from being poured out.

[0343] In other embodiments, the dust blocking sheet 700 is only an annular sheet which is easy to deform, and is sleeved on the mounting column 111. Thus, the dust blocking sheet 700 is bent to a corresponding degree to change the shielding degree of the cavity 101 under the wind pressure in the cavity 101, thereby opening the cavity to a certain degree to enable the air carrying impurities to be sucked into the cavity 101; and the dust blocking sheet 700 returns to the original sheet shape to change the shielding degree of the cavity 101 under the condition that the wind pressure in the cavity 101 stops, thereby closing the cavity to a certain degree to prevent the impurities in the cavity 101 from being poured out.

[0344] Please refer to FIG. 39, the rotating shaft part 730 is connected with the mounting end 710 and the rotating end 720 at both ends, and the thickness of the rotating shaft part 730 is less than that of the mounting end 710 and the rotating end 720, thereby forming a flexible hinge structure between the mounting end 710 and the rotating end 720, which is conducive to the rotation of the rotating end 720 of the dust blocking sheet 700, and prevents the rotating end 720 from rotating too small when the wind force is small, thereby affecting the suction of garbage and wasting wind force.

[0345] The annular design of the dust blocking sheet 700 enables it to adapt to the shape of the cavity 101, effectively open or close the opening part of the cavity 101 under the action of wind pressure, prevent dust and garbage from escaping during the dust collection process, and ensure complete suction of dust and particulate matter.

[0346] In other embodiments, the material of the dust baffle 700 can be polyvinyl chloride or thermoplastic polyurethane elastomer, or other materials that are relatively soft and easy to deform. In addition, the number of connecting ribs 112 is 3 in the figure in order to strengthen the mounting strength of the mounting column 111 on the first shell 110. In other embodiments, the connecting ribs 112 can also be 2, 5, or 7 or more. The plurality of connecting ribs 112 are circumferentially arranged around the axis of the first shell 110, or the number of connecting ribs 112 can be only one under the condition of ensuring the mounting strength of the mounting column 111, which is not specifically limited here.

[0347] In some embodiments, the connecting ribs 112 are circumferentially arranged in a direction perpendicular to the airflow (i.e., the axis direction of the first shell 110), and the connecting ribs 112 are close to the dust suction port 102 on one side in the airflow direction. From the connection between the connecting rib 112 and the first shell 110 to the connection between the connecting rib 112 and the mounting column 111, the thickness of the connecting rib 112 gradually decreases, and the profile is smoothly transitioned. That is, the connecting rib 112 is recessed at the dust suction port 102. This can reduce the volume of the connecting rib 112 while ensuring the mounting strength of the mounting column 111 and the first shell 110, and the smoothly transitioned side of the connecting rib 112 close to the dust suction port 102 can reduce the resistance when the garbage is sucked into the dust chamber 101b, i.e., increase the suction strength.

[0348] In the embodiments, the mounting column 111 is provided with a mounting protrusion 111a at the end away from the dust suction port 102 in the airflow direction. The dust baffle 700 is sleeved onto the mounting column 111 by its elasticity in a short-term expanded profile manner. The inner diameter of the mounting end 710 is the same as the outer diameter of the mounting column 111, and the mounting end 710 is adapted to be mounted on the mounting column 111. In the airflow direction, one side of the dust baffle 700 abuts against the connecting rib 112, and the other side abuts against the mounting protrusion 111a, thereby achieving fixed installation of the dust baffle 700 without swinging or displacement due to wind pressure. The embodiments of the present application achieve fixed installation on the dust removal equipment 10 by sleeving, which is simpler in structure design, has fewer parts and assembly steps, and is more secure compared to the traditional bonding or clamping installation method, which is prone to falling off or loosening under the action of wind pressure. Therefore, the service life of the dust baffle 700 is longer, and the user experience is stronger.

[0349] Further, the mounting protrusion 111a on the side away from the dust suction port 102 in the airflow direction has a chamfer, which can facilitate the installation of the dust blocking sheet 700 in the production process. When installing, the dust blocking sheet 700 can gradually increase the inner hole profile of the mounting end 710 by using the profile of the chamfer, so as to slide out the mounting protrusion 111a and achieve installation. Further, the number of mounting protrusions 111a can be three, which are distributed in a circumferential array perpendicular to the airflow. The mounting protrusions 111a are arranged in this way, which can further facilitate the installation of the dust blocking sheet 700. When the size of the mounting end 710 that is not easy to fit into is greater than the diameter of the inner hole of the mounting protrusion 111a, the mounting end 710 can be installed by sequentially fitting into the mounting protrusions 111a one by one, so as to reduce the degree of deformation of the mounting end 710 during installation, and further reduce the difficulty of installation of the mounting end 710, and further ensure the installation strength of the dust blocking sheet 700 on the first shell 110.

[0350] In some embodiments, the rotating end 720 and the airflow direction are 75°, and the side of the rotating end 720 away from the dust suction port 102 is inwardly inclined to the axis of the first shell 110 in the airflow direction. Because the shell is an elongated structure in the embodiments of the present application, the cross section of the dust cavity 101b is small, and the angle between the rotating end 720 and the airflow can increase the radial length of the rotating end 720, so as to enlarge the shielding effect during rotation, and the area of the rotating end 720 is larger, which is more conducive to receiving wind power, so that the rotating end 720 is more easily rotated. Among them, the rotating end 720 and the airflow direction are 75°, which is a more optimal scheme. In other embodiments, the rotating end 720 can also be at different angles such as 45°, 30° or 90°.

[0351] In some embodiments, the profile of the side of the first shell 110 close to the dust suction port 102 gradually decreases, and the thickness of the first shell 110 as a whole remains uniform, that is, the profile of the side of the dust cavity 101b close to the dust suction port 102 gradually decreases, so that the first shell 110 close to the dust suction port 102 has a smaller dust suction range, which is convenient for user operation. In addition, the rotating end 720 and the airflow direction are inclined, and the profile of the side of the dust cavity 101b close to the dust suction port 102 is reduced. When the dust cleaning device 10 is inverted or inclined, the garbage will reversely abut the inner wall of the first shell 110 to form a self-locking, which further prevents the garbage from leaking out of the dust suction port 102, and can improve the user experience.

[0352] The technical effect of the above scheme is that through the ingenious combination of the mounting column, the connecting rib and the dust blocking sheet of the first shell, effective sealing of the cavity and reasonable control of the wind pressure are realized. The sealing design of the dust blocking sheet can effectively prevent dust leakage and ensure that dust does not flow back during the dust collection process, thereby achieving the best dust removal effect by fully utilizing the wind pressure. In addition, through the dynamic adjustment of the dust blocking sheet, the portable dust removal equipment can automatically adjust the sealing state of the cavity according to the actual working requirements, thereby maintaining good wind pressure and enhancing the suction force.

[0353] For the dust blocking sheet 700, the dust blocking sheet 700 is arranged in the cavity 101 and is made of soft and deformable material. The dust blocking sheet 700 is used to deform under the action of wind pressure, thereby changing the shielding degree of the cavity 101 to seal or open the cavity.

[0354] The dust blocking sheet 700 can not only suck garbage from the dust suction port 102 into the cavity 101, but also prevent the garbage stored in the cavity 101 from spilling out of the dust suction port 102 during dumping or use.

[0355] In other embodiments, the material of the dust blocking sheet 700 can be sponge, polyvinyl chloride or thermoplastic polyurethane elastomer, etc.

[0356] In the embodiments of the present application, in order to strengthen the shielding effect of the dust blocking sheet 700 on the cavity 101 and reduce the wear of the dust blocking sheet 700 by the external environment, the dust blocking sheet 700 is arranged inside the cavity 101. However, in some embodiments, the dust blocking sheet 700 can also be partially arranged in the cavity 101 to shield the cavity 101.

[0357] The technical effect of the above scheme is that through the ingenious structure design and combination of the shell and the dust blocking sheet, a more reasonable cavity sealing structure is formed, and effective sealing of the cavity and reasonable control of the wind pressure are realized. The sealing design of the dust blocking sheet can effectively prevent the leakage of dust and other sucked garbage, and ensure that dust does not flow back during the dust collection process, thereby achieving the best dust removal effect by fully utilizing the wind pressure. In addition, through the dynamic adjustment of the dust blocking sheet, the dust blocking structure for the dust removal equipment can automatically adjust the sealing state of the cavity according to the actual working requirements, thereby maintaining good wind pressure and enhancing the suction force.

[0358] Those skilled in the art can understand that the dust blocking structure for the dust removal equipment shown is only a block diagram of part of the structure related to the scheme of the present application, and does not constitute a limitation on the dust removal equipment to which the scheme of the present application is applied. The specific dust blocking structure can include more or fewer components than those shown in the figure, or combine certain components, or have a different component arrangement.

[0359] In an embodiment, referring to FIG. 40, for the dust barrier 700, the dust barrier 700 is a flat ring structure, a curved ring structure or a tapered ring structure, the dust suction port 102 is circular, and the outer ring diameter of the dust barrier 700 is greater than or equal to the diameter of the dust suction port 102; wherein, in the case that the dust barrier 700 does not deform, the dust barrier 700 completely closes the dust suction port 102.

[0360] Specifically, in FIG. 43a, the dust barrier 700 is a flat ring structure, which includes an inner ring 710 and an outer ring 720; in FIG. 43b, the dust barrier 700' is a curved ring structure, which includes an inner ring 710' and an outer ring 720'; in FIG. 43c, the dust barrier 700 is a tapered ring structure, which includes an inner ring 710" and an outer ring 720", wherein the shape of the dust suction port 102 corresponding to each dust barrier is circular. Further, referring to FIG. 2, the diameter of the outer ring 720 of the dust barrier 700 is greater than or equal to the diameter of the dust suction port 102; wherein, in the case that the dust barrier 700 does not deform under the action of the wind pressure moment, i.e. in the case that the dust barrier 700 does not deform, the dust barrier 700 is in the initial shape, which can completely close the dust suction port 102.

[0361] Wherein, the ring design of the dust barrier 700 can adapt to the shape of the cavity 101, effectively open or close the opening part of the cavity 101 under the action of the wind pressure, prevent dust and garbage from escaping during the dust collection process, and ensure complete suction of dust and particulate matter.

[0362] The technical effect of the above scheme is that by providing three structure options of flat ring, curved ring and tapered ring, the needs of different users and use scenarios can be met. And through the design of the dust barrier, it can be ensured that the dust suction port is completely closed without deformation, preventing dust from entering the interior of the device and improving the service life of the device.

[0363] In an embodiment, the dust removal device includes a driving source 300, a filter assembly 400 and a cleaning accessory 200 arranged in the cavity 101, the driving source 300 includes an output shaft 310 coaxially arranged towards the dust suction port 102; wherein the output shaft 310 is a cylindrical ring structure, and the diameter of the output shaft 310 is the same as the inner ring diameter of the dust barrier 700, so that the dust barrier 700 can be installed on the output shaft 310.

[0364] Specifically, the dust blocking sheet 700 is only a ring-shaped sheet which is easy to be deformed. Wherein, the dust blocking sheet 700 is sleeved on the output shaft 310 of the driving motor of the driving source 300, so that when the driving source 300 is started, the output shaft 310 of the driving motor drives the dust blocking sheet 700 to rotate synchronously, and wind pressure is generated in the cavity 101, then the dust blocking sheet 700 is deformed to a corresponding degree under the condition of wind pressure generated in the cavity 101, so as to change the degree of shielding of the cavity 101, thereby opening the cavity 101 to a certain extent, so that the air carrying impurities is sucked into the cavity 101; and under the condition that the wind pressure in the cavity 101 is stopped, the dust blocking sheet 700 restores to the original sheet shape, so as to change the degree of shielding of the cavity 101, thereby closing the cavity 101 to a certain extent, so that the impurities in the cavity 101 cannot be poured out.

[0365] In another embodiment, referring to FIG. 41, the shell 100 further comprises a mounting column 111 and a connecting rib 112, wherein the connecting rib 112 is arranged in the cavity 101, and one end of the connecting rib 112 is fixed to the inner wall of the shell 100, and the other end is fixed to the mounting column 111, so as to fix at least part of the mounting column 111 in the cavity 101 and coaxially arrange the dust suction port 102 with the mounting column 111; the mounting column 111 is a cylindrical ring structure, and the diameter of the mounting column 111 is the same as the inner ring diameter of the dust blocking sheet 700, so that the dust blocking sheet 700 is sleeved and mounted on the mounting column 111.

[0366] In some embodiments, referring to FIG. 42, the mounting column 111 has a cylindrical outer contour, and the connecting rib 112 is arranged in the cavity 101, and the connecting rib 112 has a rib plate structure, and the number of the connecting rib 112 is three, and the three connecting ribs 112 are circumferentially arranged around the axis of the shell 100, and the connecting rib 112 connects the mounting column 111 and the inner wall of the shell 100 respectively, and one end of the connecting rib 112 is fixed to the inner wall of the shell 100, and the other end is fixed to the mounting column 111, and the arrangement of the connecting rib 112 can not only fix the mounting column 111 on the shell 100, but also avoid the airway.

[0367] In the embodiments of the present application, the number of the connecting rib 112 is three in order to strengthen the mounting strength of the mounting column 111 on the shell 100, but the specific number of the connecting rib 112 is not limited in the present application, and in other embodiments, the connecting rib 112 can also be two, five or seven or more, and the plurality of connecting ribs 112 are circumferentially arranged around the axis of the shell 100, or under the condition of ensuring the mounting strength of the mounting column 111, the number of the connecting rib 112 can be only one.

[0368] In the embodiments of the present application, in order to improve user experience and enhance the appearance of the product, the mounting column 111 and the connecting rib 112 are all arranged inside the cavity 101, but the present application is not limited thereto, and in some embodiments, the mounting column 111 and the connecting rib 112 can be partially arranged inside the cavity 101, so as to achieve the sleeving installation of the dust screen 700.

[0369] In some embodiments, as shown in FIG. 42, the mounting column 111 is provided with a mounting protrusion 111a at one end away from the dust suction port 102 in the airflow direction, and the dust screen 700 is sleeved onto the mounting column 111 by the elasticity of the dust screen 700 in a short-term expanded profile manner. In the airflow direction, one side of the dust screen 700 abuts against the connecting rib 112, and the other side abuts against the mounting protrusion 111a, so as to achieve the fixed installation of the dust screen 700, and the dust screen 700 will not swing or displace due to the action of wind pressure.

[0370] In the embodiments of the present application, the fixed installation on the dust removal equipment is achieved by the sleeving manner, and compared with the traditional bonding or clamping installation manner, the structure design is simpler, the number of parts and the assembly steps are fewer, and compared with the bonding or clamping which is easy to fall off or loosen under the action of wind pressure, the installation manner of the embodiments of the present application is more firm, so as to prolong the service life of the dust screen 700 and improve the user experience.

[0371] Further, the mounting protrusion 111a is provided with a chamfer on the side away from the dust suction port 102 in the airflow direction, and the setting of the chamfer can facilitate the installation of the dust screen 700 in the production process. When installing, the dust screen 700 can gradually increase the inner hole profile of the dust screen 700 by using the profile of the chamfer, so as to slide out of the mounting protrusion 111a and achieve installation. Further, the number of mounting protrusions 111a can be three, and the three mounting protrusions 111a are circumferentially arranged in a direction perpendicular to the airflow. The mounting protrusions 111a are arranged in this interval manner, which can further facilitate the installation of the dust screen 700. When the dust screen 700 is not easy to be sleeved into the mounting protrusion 111a with a size greater than the inner hole diameter of the dust screen 700, the dust screen 700 can be installed by being sleeved into the mounting protrusions 111a one by one, so as to reduce the deformation degree of the dust screen 700 during installation, and further reduce the difficulty of the dust screen 700 during installation, and further ensure the installation strength of the dust screen 700 on the shell 100.

[0372] In some embodiments, the above two dust screen installation structures, i.e., the dust screen is installed on the output shaft of the motor and the dust screen is installed on the mounting column of the shell, can be independently arranged on the dust removal equipment, or can be combined as a whole structure and arranged on the dust removal equipment, which is not limited herein.

[0373] The technical effect of the above scheme is that by installing the dust baffle in two different ways in the cavity, the stability of the dust baffle in the cavity can be ensured, and displacement or damage caused by vibration or wind pressure changes can be reduced. Users can choose the appropriate installation method according to specific use requirements to achieve the best use effect.

[0374] In an embodiment, referring to FIG. 41, the thickness of the connecting rib 112 gradually decreases from the connection between the connecting rib 112 and the shell 100 to the connection between the connecting rib 112 and the mounting column 111, and the profile of the connecting rib 112 is recessed towards the inside of the cavity 101, so as to reduce the resistance when the suction port 102 sucks in impurities.

[0375] Specifically, the connecting rib 112 is circumferentially arranged in a direction perpendicular to the airflow (i.e., the axis direction of the suction port 102), and the thickness of the connecting rib 112 gradually decreases from the side of the connecting rib 112 close to the suction port 102 from the connection between the connecting rib 112 and the shell 100 to the connection between the connecting rib 112 and the mounting column 111, and the profile of the connecting rib 112 is smoothly transitioned, i.e., the connecting rib 112 is recessed at the suction port 102, which can reduce the volume of the connecting rib 112 while ensuring the installation strength of the mounting column 111 and the shell 100, and the smoothly transitioned side of the connecting rib 112 close to the suction port 102 can reduce the resistance when garbage is sucked into the cavity 101, i.e., increase the suction strength.

[0376] The technical effect of the above scheme is that by gradually reducing the thickness of the connecting rib and designing the recessed profile, the airflow resistance when the suction port sucks in impurities is effectively reduced, and the dust collection efficiency is improved; and by designing the connecting rib, the airflow path can be optimized to ensure smooth airflow and reduce vortex and backflow, further improving the working efficiency of the device.

[0377] In an embodiment, the dust baffle 700 can be only one easily deformed annular sheet, which is sleeved in the mounting column 111, so that the dust baffle 700 bends to a corresponding degree under the wind pressure in the cavity 101 to change the degree of shielding of the cavity 101, so as to open the cavity 101 to a certain extent to allow air carrying impurities to be sucked into the cavity 101; and under the condition that the wind pressure in the cavity 101 stops, the dust baffle 700 restores to the original sheet shape to change the degree of shielding of the cavity 101, so as to close the cavity 101 to a certain extent to prevent impurities in the cavity 101 from being discharged.

[0378] In another embodiment, referring to FIG. 42, the dustproof sheet 700 comprises a mounting portion 710 and a dustproof portion 720, wherein the mounting portion 710 is a cylindrical ring structure, which is sleeved on the output shaft 310 of the driving source 300 or the mounting column 111 of the housing 100; the dustproof portion 720 is made of soft material and is connected to the mounting portion 710, so as to be bent and deformed under the action of the wind pressure in the cavity 101, so as to close or open the cavity 101.

[0379] The mounting portion 710 is a cylindrical ring structure, which is sleeved on the mounting column 111, so as to realize the mounting of the dustproof sheet 700 on the housing 100. The mounting portion 710 is in the form of a cylindrical ring structure and the outer contour of the mounting column 111 is in the form of a cylinder, which is a matching mounting therebetween and corresponds to the shape of the cavity 101, so that the mounting portion 710 is more uniform in stress and is not easy to be damaged due to internal stress. However, the specific shape of the mounting portion 710 and the mounting column 111 is not limited in the present application. For example, in some embodiments of the present application, the cross section of the outer contour of the mounting column 111 can be in the form of an ellipse, a triangle, a rectangle or other polygons. The inner contour of the mounting portion 710 is preferably matched with the outer contour of the mounting column 111, but the inner contour of the mounting portion 710 can also not be matched with the outer contour of the mounting column 111 as long as the mounting strength of the dustproof sheet 700 is ensured, and the inner and outer contours of the mounting portion 710 can also not be consistent.

[0380] In some embodiments, referring to FIG. 42, the dustproof portion 720 is in the form of a circular ring sheet structure, the dustproof portion 720 and the airflow direction are at an angle of 75°, and the side of the dustproof portion 720 away from the dust suction port 102 is inwardly inclined to the axis of the housing 100 in the airflow direction. Because the housing is in the form of an elongated structure and the cross section of the cavity 101 is small in the embodiments of the present application, the radial length of the dustproof portion 720 can be increased by setting the dustproof portion 720 and the airflow at an acute angle, so as to enlarge the shielding effect during rotation, and the area of the dustproof portion 720 is larger, which is more conducive to receiving wind force, so that the dustproof portion 720 is more easily rotated.

[0381] In the embodiments of the present application, the dustproof portion 720 and the airflow direction are at an angle of 75°, which is a relatively optimal scheme, but the present application does not limit this. In other embodiments of the present application, the dustproof portion 720 can also be at an angle of 45°, 30° or 90° or other different angles.

[0382] In the embodiments of the present application, in order to adapt to the profile of the cavity 101, the outer profile of the dust blocking part 720 can be set as a circle to increase the shielding effect on the cavity 101, and the dust blocking part 720 is set in a sheet manner to be easy to be deformed, but the specific shape of the dust blocking part 720 is not limited in the present application, in other embodiments of the present application, the outer profile of the dust blocking part 720 can be a shape adapted to the cross-sectional shape of the cavity 101, such as an ellipse, a triangle, a rectangle, or a polygon, or a shape not adapted to the cavity 101, to at least partially shield the cavity 101, and the dust blocking part 720 can also be designed to have a certain thickness to increase the strength inside the dust blocking sheet 700.

[0383] In another embodiment, referring to FIG. 42, the dust blocking sheet 700 can further include a rotating shaft part 730 connected to the mounting part 710 and the dust blocking part 720 at two ends, in addition to the mounting part 710 and the dust blocking part 720; wherein under the action of the wind pressure in the cavity 101, the mounting part 710 and the dust blocking part 720 are driven to relatively rotate around the rotating shaft part 730 by the wind pressure moment received by the dust blocking part 720, so as to change the shielding degree on the cavity 101 to close or open the cavity 101.

[0384] Specifically, the mounting part 710 is sleeved on the mounting column 111, the dust blocking part 720 rotates under the action of the wind pressure to change the shielding degree on the cavity 101, the rotating shaft part 730 is connected to the mounting part 710 and the dust blocking part 720 at two ends, and the mounting part 710 and the dust blocking part 720 can rotate around the rotating shaft part 730.

[0385] Among them, for the rotating shaft part 730, the rotating shaft part 730 is annular as a whole, and the thickness of the rotating shaft part 730 is less than the thickness of the mounting part 710 and the dust blocking part 720, so as to form a flexible hinge structure between the mounting part 710 and the dust blocking part 720, thereby facilitating the rotation of the dust blocking part 720, preventing the rotation amplitude of the dust blocking part 720 from being too small when the wind force is small, thereby affecting the suction of garbage, and wasting the wind force.

[0386] In the embodiments of the present application, the rotating shaft part 730 is annular to adapt to the shape of the mounting part 710 and the dust blocking part 720, so as to keep the shape and wall thickness consistent, so that the dust blocking sheet 700 is more uniform in stress and is not easy to be damaged due to stress imbalance, but the specific shape of the rotating shaft part 730 is not limited in the present application, in other embodiments of the present application, the rotating shaft part 730 can have other shapes.

[0387] In some embodiments, as shown in FIG. 42, the mounting column 111 at the end away from the dust suction port 102 in the airflow direction is provided with a mounting protrusion 111a, and the dust blocking sheet 700 is sleeved onto the mounting column 111 of the housing 100 or the output shaft 310 of the driving source 300 by the elasticity of the dust blocking sheet 700 in a short-term expanded profile manner from the mounting protrusion 111a during installation, and the inner diameter of the mounting portion 710 and the outer diameter of the mounting column 111 or the output shaft 310 are the same, the mounting portion 710 is adapted to be mounted on the mounting column 111 or the output shaft 310, and one side of the dust blocking sheet 700 abuts against the connecting rib 112 and the other side abuts against the mounting protrusion 111a in the airflow direction, so as to realize the fixed installation of the dust blocking sheet 700 and prevent the dust blocking sheet 700 from swinging or displacing due to the wind pressure.

[0388] Further, the number of the mounting protrusions 111a is three, and the three mounting protrusions 111a are circumferentially arranged in a direction perpendicular to the airflow. The mounting protrusions 111a are arranged in this interval manner, which can further facilitate the installation of the dust blocking sheet 700. When the size of the mounting portion 710 that is not easy to be sleeved into the mounting protrusion 111a is greater than the inner hole diameter of the mounting portion 710, the mounting portion 710 can be installed by being sleeved into the mounting protrusions 111a one by one, so as to reduce the deformation degree of the mounting portion 710 during installation, and further reduce the difficulty of the installation of the mounting portion 710, and further ensure the installation strength of the dust blocking sheet 700 on the housing 100.

[0389] In the embodiments of the present application, the number of the mounting protrusions 111a is set to three by comprehensively considering the installation strength and installation difficulty of the dust blocking sheet 700, but the present application does not limit the specific number of the mounting protrusions 111a. In other embodiments of the present application, the number of the mounting protrusions 111a can also be two, four or six, and in some embodiments of the present application, the mounting protrusions 111a can also be arranged in a complete ring shape to ensure the installation strength of the dust blocking sheet 700.

[0390] In some embodiments, the mounting protrusion 111a on the side away from the dust suction port 102 in the airflow direction is chamfered. The chamfered arrangement can facilitate the installation of the dust blocking sheet 700 during production. During installation, the dust blocking sheet 700 can gradually increase the inner hole profile of the mounting portion 710 by using the profile of the chamfer, so as to slide out of the mounting protrusion 111a and realize the installation. In some embodiments of the present application, the side of the mounting protrusion 111a away from the dust suction port 102 in the airflow direction can also be provided with a round corner to facilitate the installation of the dust blocking sheet 700.

[0391] In the embodiments of the present application, the dust blocking sheet 700 is installed on the mounting column 111 of the shell 100 or the output shaft 310 of the driving source 300 in a sleeving manner, which is simple and firm in installation. Compared with the traditional installation by clamping or bonding, the dust blocking sheet 700 of the present application is less likely to fall off, thereby being beneficial to improving the service life of the dust blocking structure 1. On the other hand, the dust blocking sheet 700 is installed on the mounting column 111 of the shell 100 or the output shaft 310 of the driving source 300 in a sleeving manner, without the need for additional assembly parts. The assembly steps are simple, and the installation part 710 can be sleeved into the mounting column 111 or the output shaft 310 from the mounting protrusion 111a to complete the installation. The assembly state is also easy to identify, thereby reducing the installation steps and further reducing the production cost.

[0392] The above scheme has the beneficial effects that two different dust blocking sheet designs are provided, which respectively have flexible dust blocking sheet design and rotation mechanism, can generate effective bending deformation and relative rotation under the action of wind pressure in the cavity, to realize the closing or opening of the cavity. Among them, the two kinds of dust blocking sheets can dynamically respond to the change of wind pressure in the cavity, adjust the form in real time, realize efficient closing and opening, and improve the sealing performance of the equipment; and the second kind of dust blocking sheet can realize relative rotation under the action of wind pressure through the design of the rotation shaft part, further enhancing the shielding and ventilation capacity of the cavity.

[0393] In one embodiment, when the dust blocking sheet 700 is a planar circular ring structure, the dust blocking part 720 is arranged at an angle of 90° with the axis direction of the dust suction port 102; or, when the dust blocking sheet 700 is a curved circular ring structure, the curvature of the dust blocking part 720 is 0.9, and the dust blocking part 720 is coaxial with the dust suction port 102; or, when the dust blocking sheet 700 is a conical circular ring structure, the conical angle of the dust blocking part 720 is 15°, and the dust blocking part 720 is coaxial with the axis of the dust suction port 102.

[0394] Specifically, referring to FIG. 43, in FIG. 43a, the dust blocking sheet 700 is a conical circular ring structure, the conical angle of the dust blocking part 720 of the dust blocking sheet 700 is 15°, and the dust blocking part 720 is coaxial with the axis of the dust suction port 102; in FIG. 11b, the dust blocking sheet 700' is a curved circular ring structure, the curvature of the dust blocking part 720' of the dust blocking sheet 700' is 0.9, and the dust blocking part 720' is coaxial with the dust suction port 102; in FIG. 11c, the dust blocking sheet 700" is a planar circular ring structure, and the dust blocking part 720" of the dust blocking sheet 700" is arranged at an angle of 90° with the axis direction of the dust suction port 102.

[0395] In the three mounting modes of the dust screen in FIG. 43, the mounting column 111 and the connecting rib 112 of the shell 100 are used for fixing, and in other embodiments, the dust screen can also be fixed by sleeving the output shaft 310 of the driving motor of the driving source 300, which is not specifically limited here.

[0396] The above scheme has the beneficial effect that the user can select appropriate dust screen shape and configuration according to different working environment and needs, thereby improving the applicability of the dust removal equipment. The configuration relationship between the dust screen of different shapes and the dust suction port can effectively optimize the flow of air flow, reduce the interference and resistance of air flow, and improve the overall performance of the equipment.

[0397] In an embodiment, in the case of a curved circular ring structure or a conical circular ring structure of the dust screen, at least part of the dust screen extends out of the dust suction port, so that when the dust removal equipment is tilted, the dust screen abuts against the inner wall of the shell, thereby forming a self-locking of the dust suction port.

[0398] Specifically, please refer to FIG. 44, in FIG. 44a, the dust screen 700 is a conical circular ring structure, and it is sleeved on the output shaft 310 of the driving source 300 through the mounting portion 710, wherein the output shaft 310 of the driving source 300 has a part of the area extending out of the dust suction port 102, so that part of the dust screen 700 also extends out of the dust suction port 102, so that when the dust removal equipment 10 is tilted or the dust screen 700 is in the initial state, part of the dust screen 700 abuts against the inner wall of the shell 100, thereby forming a self-locking of the dust suction port 102. And in FIG. 12b, the dust screen 700' is a curved circular ring structure, and it is sleeved on the output shaft 310 of the driving source 300 through the mounting portion 710', wherein the output shaft 310 of the driving source 300 has a part of the area extending out of the dust suction port 102, so that part of the dust screen 700' also extends out of the dust suction port 102, so that when the dust removal equipment 10 is tilted or the dust screen 700' is in the initial state, part of the dust screen 700' abuts against the inner wall of the shell 100, thereby forming a self-locking of the dust suction port 102.

[0399] In some embodiments, as shown in FIG. 44, the shell 100 near the dust suction port 102 gradually decreases in profile towards the direction close to the dust suction port 102, specifically, the profile of the side of the shell 100 close to the dust suction port 102 gradually decreases, and the thickness of the shell 100 as a whole uniformly remains consistent, that is, the profile of the side of the cavity 101 close to the dust suction port 102 gradually decreases, so that the shell 100 near the dust suction port 102 has a smaller dust suction range, which is convenient for the user to operate.

[0400] In some embodiments, the dust blocking part 720 and the airflow direction are obliquely arranged, and the cavity 101 is close to the dust suction port 102. Due to the reduced profile, when the dust removal device 10 is inverted or inclined, the garbage will abut the dust blocking piece 700 to the inner wall of the shell 100 in reverse, thereby forming a self-locking, further preventing garbage from leaking out of the dust suction port 102, which can improve the user experience. On the other hand, it can also reduce the size of the dust suction port 102, making it easier for users to clean small and precise instruments.

[0401] The beneficial effects of the above scheme are that by the extension design of the dust blocking part 720, a self-locking can be formed when the device is inclined, effectively preventing garbage from leaking out of the dust suction port 102, improving the reliability of the device. Among them, whether the dust blocking piece 700 is a curved ring structure or a conical ring structure, it can maintain good sealing performance in the inclined state, ensuring the dust removal effect, and by preventing garbage from leaking out, the working efficiency of the dust removal device 10 can be improved, ensuring that the ideal dust removal effect can be achieved under various working conditions.

[0402] Embodiment Nine

[0403] During the use of the portable dust removal device 10, especially in environments with insufficient light or narrow space, users often have difficulty accurately identifying the cleaning area. This can result in less than ideal cleaning results or miss some difficult-to-detect dirt and dust. Therefore, it is of great practical significance to develop a portable dust removal device 10 that can provide lighting. By integrating a light assembly in the device, cleaning efficiency can be effectively improved, ensuring that the cleaning area is fully illuminated.

[0404] Please continue to refer to FIG. 3, the portable dust removal device 10 also includes a light assembly 800, which is installed on the first mounting assembly 130 and surrounds the output shaft 310 of the driving source 300. When the light assembly 800 is working, the light emitted from the dust suction port 102 illuminates the area to be cleaned.

[0405] In some embodiments, when the portable dust removal device 10 is turned on, the light assembly 800 will work simultaneously, ensuring that continuous lighting is provided while the user is cleaning. The implementation of this function not only makes the device more practical, but also effectively reduces the cleaning omissions caused by insufficient light.

[0406] Please refer to Figure 45, in order for the user to effectively use the light to illuminate the dust in the dark, the light assembly 800 specifically includes a circuit board 810 and a light emitting piece 820. Wherein the circuit board 810 is annular, the circuit board 810 is installed on the first mounting assembly 130 and arranged around the output shaft 310 of the motor of the driving source 300, the light emitting piece 820 is a led lamp bead, the number of the light emitting piece 820 is 6, the 6 light emitting pieces 820 are welded on the circuit board 810 in a circumferential array, and the light of the light emitting piece 820 is arranged towards the dust suction port 102, when the light emitting piece 820 is in working condition, the light emitted will be emitted from the dust suction port 102 to illuminate the surface to be cleaned.

[0407] Wherein, the light emitting piece 820 selects the led lamp bead in order to reduce the volume and cost of the light assembly 800, in other embodiments, the light emitting piece 820 can also use other types of lamps such as incandescent lamp, fluorescent lamp or laser lamp, which is not limited here. In addition, in the embodiment of the application, 6 light emitting pieces 820 are arranged in a circumferential array, which can reduce the size of the light emitting piece 820 in a single direction while obtaining more uniform and brighter light, and the dust removal equipment 10 is cylindrical as a whole, the user holds the first shell 110 can rotate 360° holding, there is no difference in use angle, so the light emitting piece 820 arranged in a circumferential array can emit light uniformly, so that the user can hold and use the light at different angles, and the lighting effect can remain consistent.

[0408] In other embodiments, the light emitting piece 820 can only select one, or select 2, 4 or 7 or more, while the intensity can meet the demand, the plurality of light emitting pieces 820 can be arranged in a circumferential array, or can be arranged irregularly on the circuit board 810, which is not limited here. For example, the first shell 110 is provided with a holding positioning structure or the first shell 110 is oval as a whole, the user holds the first shell 110 when using the dust removal equipment 10 will have a specific angle, the light emitting piece 820 can be arranged in a cluster and emitted from the dust suction port 102 at a fixed angle.

[0409] In some embodiments, in order to simplify the structure of the light assembly 800, and reduce the cost of the dust removal equipment 10 while being more firmly installed, the light emitting piece 820 is directly welded to the circuit board 810 by welding, in other embodiments, the light emitting piece 820 can also be fixed on the first mounting assembly 130 by setting the buckle structure, and the electrical connection between the light emitting piece 820 and the circuit board 810 is realized by the way of wire, or in some embodiments, the light emitting piece 820 can be fixed to the circuit board 810 by the way of plug-in and realize the electrical connection between the light emitting piece 820 and the circuit board 810.

[0410] Further, referring to FIG. 46, the light assembly 800 further comprises a baffle 830, which is a circular transparent plate structure, and the baffle 830 is made of transparent polycarbonate. The baffle 830 is arranged on the first fixing portion 131 to enclose the light emitting element 820 and the circuit board 810, so as to prevent dust from adhering to the dust removal device 10 during operation to shield the light emitting element 820, thereby affecting the light intensity of the light emitting element 820, and the adhesion of dust is likely to affect the electrical connection between the light emitting element 820 and the circuit board 810. The baffle 830 is made of transparent material, and the light emitting element 820 can directly pass through the baffle 830 without causing loss of light intensity.

[0411] In some embodiments, the outer diameter of the baffle 830 is the same as the outer diameter of the first fixing portion 131. The baffle 830 is provided with positioning blocks 831 on both sides of the circular arc, as shown in FIG. 13. The first fixing portion 131 is provided with positioning grooves 131a. The baffle 830 is accommodated in the first fixing portion 131, and the positioning blocks 831 are respectively accommodated in the positioning grooves 131a. The side of the baffle 830 away from the dust suction port 102 is a mounting surface, and the mounting surface is attached with an adhesive. The baffle 830 is bonded to the bottom surface of the positioning grooves 131a through the positioning blocks 831, so as to realize the installation of the baffle 830 on the first fixing portion 131.

[0412] In some embodiments, the specific material and shape of the baffle 830 can also be polyethylene terephthalate, polyvinyl chloride, or tempered glass, or other transparent or light-transmitting materials, which are not limited in the present application. The baffle 830 is designed in a circular shape to match the contour shape of the first fixing portion 131. However, in other embodiments, when the interface of the first fixing portion 131 is elliptical or polygonal, the baffle 830 can match the shape of the first fixing portion 131 and correspondingly be elliptical or polygonal. Alternatively, the baffle 830 can be arranged without matching the shape of the first fixing portion 131, so as to partially shield the light emitting element 820 or extend in the axial direction of the first housing 110 in an arc shape, such as a circular ring or a circular conical sidewall. The two ends of the baffle 830 are connected between the mounting column 111 and the first fixing portion 131 to block and shield the light emitting element 820.

[0413] Further, please continue to refer to FIG. 1 and FIG. 47, the light assembly 800 further comprises a light blocking piece 840, the light blocking piece 840 is annular as a whole, and the light blocking piece 840 is annularly arranged on the side of the first shell 110 close to the dust suction port 102. Wherein, the first mounting assembly 130, the connecting portion 133, the base 210 and the first shell 110 can all be light-transmissive, and the dust removal equipment 10 is provided with the light blocking piece 840 outside the dust suction port 102 to block part of the light emitted by the light emitting piece 820, so that the light emitted by the light emitting piece 820 is concentrated in the corresponding dust suction range of the dust suction port 102, without forming a too large light area, and the user can intuitively judge the cleaning area of the dust removal equipment 10, and the light blocking piece 840 partially blocks the light emitted by the light emitting piece 820, which reduces the light intensity entering the user's eyes on the premise of ensuring that the cleaning area is illuminated, thereby protecting the user's eyes and making the use process more comfortable, thereby improving the user experience.

[0414] Specifically, please refer to FIG. 36 and FIG. 47, the side of the first shell 110 close to the dust suction port 102 is provided with an annular mounting gap 113, the light blocking piece 840 is accommodated and mounted in the mounting gap 113 and is adhesively fixed on the first shell 110, and the edge of the outer contour of the light blocking piece 840 and the first shell 110 is adaptively fitted to make the outer contour without obvious gap, the light blocking piece 840 is a soft glue, for example, it can be a thermoplastic polyurethane elastomer material, and is made by one-piece injection molding during production, which has soft and elastic material, thereby facilitating the user to hold during use, has better hand feeling, and has superior hardness and wear resistance, and has good oil resistance, chemical resistance and corrosion resistance, thereby preventing the dust suction port 102 from being easily worn and corroded during use, thereby improving the service life of the dust removal equipment 10 and improving the user experience.

[0415] Wherein, in order to facilitate installation and reduce production cost, the edges of the light blocking piece 840 are circular, and the shape of the mounting gap 113 is adaptively matched with the contour of the light blocking piece 840, but in other embodiments, the light blocking piece 840 can also be a multi-segment or single-segment annular structure, and the light blocking piece 840 is mounted at the dust suction port 102 of the first shell 110 to partially block the light of the light emitting piece 820, so as to reduce the area of the light area and the light emitted. In addition, in some embodiments, the outer side surfaces of the first shell 110 and the light blocking piece 840 can be provided with protrusions and recesses and other mutually embedded structures, which on the one hand can increase the area of the light blocking piece 840 on the first shell 110, facilitating the user to hold, and on the other hand can increase the appearance fashion of the dust removal equipment 10. In addition, the first shell 110 is provided in a light-transmissive manner to facilitate the user to observe the storage amount of the dust cavity 101b.

[0416] In order to reduce the installation steps, save production time, and ensure the installation strength of the light blocking piece 840, the light blocking piece 840 and the first shell 110 can be integrally injection molded by double-color injection molding, so that the light blocking piece 840 and the first shell 110 are integrally formed, but in other embodiments, the light blocking piece 840 can be separately provided with the first shell 110, and the light blocking piece 840 can be fixed to the first shell 110 by sleeving and bonding, or in some embodiments, the light blocking piece 840 can also be fixed to the first shell 110 by clamping or screwing, which is not specifically limited here.

[0417] The technical effect of the above scheme is that by integrating the light assembly on the first mounting assembly, light can be emitted and emitted from the dust suction port to illuminate the area to be cleaned. This design greatly improves the practicality of the cleaning device, allowing users to clearly observe the area to be cleaned during cleaning, making it easier to find hidden dirt and dust, thereby improving cleaning efficiency and accuracy.

[0418] The present application provides a portable dust removal device 10, please refer to FIG. 1 to FIG. 4, the portable dust removal device 10 includes a shell 100, a light assembly 800 and a controller 900. Wherein, the shell 100 is a hand-held mini shell, which has a cavity 101 inside the shell, and a dust suction port 102 communicating with the outside is arranged at one end of the cavity 101, the controller 900 is accommodated in the cavity 101 and connected with the light assembly 800, the light assembly 800 is accommodated in the cavity 101 and fixed to the shell 100, wherein, in response to the control instruction triggered by the user for the portable dust removal device 10, the controller 900 is used to control the light assembly 800 to emit light according to the control instruction, and the light is used to emit from the dust suction port 102 to illuminate the area to be cleaned.

[0419] For the light assembly 800, please refer to FIG. 49, the light assembly 800 is accommodated inside the cavity 101 and fixed to the shell 100, wherein, when the portable dust removal device 10 is turned on, the light assembly 800 will work synchronously, and the light emitted therefrom will be emitted from the dust suction port 102 to ensure continuous illumination while the user is cleaning. The implementation of this function not only makes the device more practical, but also effectively reduces the cleaning omission caused by insufficient light.

[0420] In some embodiments, the light assembly 800 can be directly fixedly connected with the shell 100 inside the cavity 101, such as buckle connection, welding point connection or pasting connection; in other embodiments, the portable dust removal device 10 can further include a first mounting assembly 130, wherein the first mounting assembly 130 is accommodated in the cavity 101 and fixed to the shell 100, and the light assembly 800 is fixedly connected with the first mounting assembly 130 in the cavity 101.

[0421] The first mounting assembly 130 comprises a first fixing part 131, a second fixing part 132 and a connecting part 133. The first fixing part 131 is a cylindrical ring structure, and the light assembly 800 is embedded and mounted in the first fixing part 131. The second fixing part 132 is fixed to the shell 100 by clamping. The connecting part 133 is a plurality of flat plate structures extending in a direction perpendicular to the axis and circumferentially arrayed. The two ends of the connecting part 133 are connected to the first fixing part 131 and the second fixing part 132, respectively. The first fixing part 131 is coaxially arranged with the cavity 101. The connecting part 133 realizes the mounting of the first fixing part 131 on the shell 100 and also realizes the circulation of the airflow.

[0422] Specifically, when the portable dust removal device 10 is in operation, the gas flows through the connecting space between the cavity 101 and the first fixing part 131, forming a continuous airflow channel, which ensures the dust removal effect of the cleaning device during use. The coaxial structure not only enhances the flowability of the airflow, but also maximally reduces the airflow resistance, ensuring that the inhaled impurities are quickly transferred to the dust chamber 101b and improving the cleaning efficiency of the device.

[0423] In the present application, the specific mounting method of the first mounting assembly 130 is not limited. For example, in other embodiments, the second fixing part 220 can be fixed on the shell 100 by screwing or inserting or other methods, and the second fixing part 220 can also be fixed on the shell 100.

[0424] In the present application, the first mounting assembly 130 is completely accommodated in the cavity 101 in order to optimize the overall structure of the dust removal device 10 and reduce the influence of the external environment on the first mounting assembly 130. In some embodiments, the first mounting assembly 130 can be partially accommodated in the cavity 101.

[0425] In the present application, the specific shape of the first mounting assembly 130 is not limited. For example, in some embodiments, the first fixing part 131 and the cavity 101 can be eccentrically arranged.

[0426] Referring to FIG. 48, the controller 900 is a control board in the portable dust removal device 10, which is a circuit board for controlling various operations in the device. It is equivalent to the “brain” of the dust removal device 10, responsible for receiving signals, processing data, issuing instructions, displaying states, etc.

[0427] In practical applications, the design of the controller 900 may vary depending on the type and functional requirements of different dust removal equipment 10. For example, a bag-type dust collector may need a control panel to achieve automatic control of the ash cleaning period, while an electrostatic precipitator may need a control panel to adjust the electric field strength and frequency. The design and implementation of the controller 900 are crucial to ensure the efficient and stable operation of the dust removal equipment 10.

[0428] In some embodiments, as shown in FIG. 48, the controller 900 is a control panel on which a triode 901 and a single-chip microcomputer 902 are arranged. The triode 901 and the single-chip microcomputer 902 are electrically connected to the light assembly 800, respectively, to achieve electrical signal control of the light assembly 800.

[0429] The triode 901 has multiple functions in the control panel, such as: the triode 901 can be used as a switch, which controls the current flow between the collector and the emitter by controlling the base current, so that it can realize the switching function of the light assembly 800 in the control circuit. The triode 901 can amplify the input signal of the light assembly 800, so that a weak control signal can drive a larger light load. In power management, the triode 901 can be used to regulate the current to ensure that the device receives appropriate current supply in different working states. In addition, the triode 901 can also be used for circuit protection to prevent overcurrent or short circuit conditions from damaging other components.

[0430] The single-chip microcomputer 902 also has multiple functions in the control panel, such as: the single-chip microcomputer 902 is the core of the control panel, responsible for receiving signals from user inputs (such as buttons, sensors, etc.), and processing them according to pre-set programs. The single-chip microcomputer 902 can process data from sensors, perform calculations and judgments, and thus control the working state of the dust removal equipment 10 (such as adjusting the suction force, switching modes, etc.). The single-chip microcomputer 902 can realize communication with other devices (such as Bluetooth, Wi-Fi), so that users can remotely control the dust collector through their mobile phones or other devices. The single-chip microcomputer 902 can also implement timing functions to control the device to work or sleep at specific times, and perform corresponding operations according to logical conditions. In addition, the single-chip microcomputer 902 can also be responsible for managing the indicator lights, display screens, etc. on the control panel, to feedback the status and fault information of the device to the user.

[0431] In a specific implementation scenario, first, the user triggers the device start instruction in the display of the portable dust removal equipment 10 by tapping, and then the controller 900 starts the portable dust removal equipment 10 according to the device start instruction, and sends an opening signal to the light assembly 800 through the triode 901 and the single-chip microcomputer 902 to control the light assembly 800 to emit light, wherein the light is directly emitted from the dust suction port 102 to illuminate the area to be cleaned.

[0432] In another specific implementation scenario, after the portable dust removal device 10 is turned on, the user triggers the device cleaning instruction in the display of the portable dust removal device 10 by tapping, and then the controller 900 drives the source and the air pressure assembly respectively through the single-chip microcomputer 902, so that the driving source drives the cleaning accessory to move, so that the cleaning accessory sweeps the garbage on the surface to be cleaned, and then the air pressure assembly drives the fan blade to rotate, so that the air pressure in the cavity 101 is generated, so that the garbage on the surface to be cleaned is sucked into the cavity 101 through the dust suction port 102, and finally the air carrying garbage sucked into the cavity 101 is filtered through the filter assembly, so that the filtered clean air is discharged from the air outlet.

[0433] The technical effect of the above scheme is that the device not only avoids the bulkiness and inconvenience of traditional cleaning tools, but also provides a portable, flexible and efficient solution to meet the expectations of modern users for portable cleaning devices. Users can easily carry the device to every corner of daily life and clean at any time, improving the quality of life. Specifically, in one aspect, the light assembly and the controller are housed in the cavity through a hand-held mini shell, greatly reducing the physical volume of the dust removal device, making the device easy to carry and suitable for cleaning needs in various occasions, thereby improving the portability and operability of the dust removal device; in another aspect, unlike the prior art, the light assembly integrated in the shell provides necessary illumination during cleaning, solving the problem of insufficient light and effectively improving the cleanliness of dirt in dead corners and gaps, thereby achieving powerful cleaning.

[0434] For the shell 100 in the above embodiment, the shell 100 further includes a detachable first shell 110 and a second shell 120, the first shell 110 and the second shell 120 together enclose the cavity 101, and the dust suction port 102 is arranged at one end of the first shell 110 away from the second shell 120; wherein the cavity 101 is divided into an installation cavity 101a and a dust cavity 101b in the first shell 110, and the light assembly 800 is installed in the dust cavity 101b.

[0435] Specifically, the structure of the shell 100 includes a detachable first shell 110 and a second shell 120, which together enclose the cavity 101. This structure design aims to improve the maintainability and operational convenience of the device, and also facilitates the user to clean and maintain separately after disassembling it.

[0436] Further, inside the cavity 101, the filter assembly is installed in the first shell 110, which divides the cavity 101 into two areas: the installation cavity 101a and the dust cavity 101b. This design makes the flow of air inside the device more orderly and effectively separates impurities from clean air.

[0437] Further, the dust suction port 102 is arranged at one end of the first shell 110 away from the second shell 120, so as to ensure that dirt and garbage can be quickly sucked in during the cleaning process. At the same time, the cleaning airflow passing through the filter assembly will form in the mounting cavity 101a and finally be discharged through the air outlet, ensuring that the released air is clean and free of pollution.

[0438] The filter assembly separates the airflow direction, which optimizes the airflow direction. The garbage on the surface to be cleaned will quickly enter the dust cavity 101b after being sucked into the cavity 101 through the dust suction port 102. The design can effectively capture and store impurities, greatly reducing the risk of impurities flowing back to the environment with the airflow. At the same time, the filtered clean airflow can smoothly pass through the mounting cavity 101a and be discharged to the air outlet, thereby improving the overall cleaning efficiency.

[0439] The technical effect of the above scheme is that by designing the cavity of the shell into a mounting cavity and a dust cavity, more efficient garbage separation and airflow optimization are achieved. After the cleaning airflow passes through the filter assembly, impurities can be effectively isolated, and the purified air can be safely discharged. In addition, the shell structure improves the use stability and cleaning performance of the equipment, not only optimizing the cleaning effect, but also greatly improving the user experience.

[0440] In one embodiment, referring to FIG. 49, the first shell 110 includes a light-transmitting portion 114 and a light-blocking portion 115. The light-transmitting portion 114 is transparent, and the dust cavity 101b is arranged in the light-transmitting portion 114 to visualize the dust cavity 101b. The light-blocking portion 115 is light-blocking, and the dust suction port 102 is arranged at one end of the light-blocking portion 115, so that when the light assembly 800 emits light, the light is concentratedly emitted from the dust suction port 102.

[0441] Specifically, the first shell 110 can be divided into a light-blocking portion 115 from the dust suction port 102 to the dust cavity 101b, and a light-transmitting portion 114 from the dust cavity 101b to the end of the shell. The light-transmitting portion 114 is transparent, so that the user can directly observe the dust suction condition in the dust cavity 101b. The light-blocking portion 115 is light-blocking, so that the light emitted from the dust cavity 101b is blocked by the light-blocking portion 115, thereby concentrating the light in the dust suction range corresponding to the dust suction port 102, without forming a large light area. The user can directly judge the cleaning area of the dust removal equipment 10, so as to reduce the light intensity entering the eyes of the user on the premise of ensuring that the cleaning area is illuminated.

[0442] In some embodiments, the light-transmitting portion 114 can be polycarbonate (PC), acrylic (PMMA), glass, etc., as long as it has the characteristics of optical transparency, light weight, and easy processing, which are not specifically limited in the present application. The light-blocking portion 115 can also be polypropylene (PP), polyvinyl chloride (PVC), ABS plastic, or metal-coated material, etc., as long as it has the characteristics of good light-blocking effect and strong durability, which are not specifically limited in the present application.

[0443] In another embodiment, referring to FIGS. 50 and 51, the portable dust removal device 10 further comprises a light-blocking piece 840; wherein the first shell 110' is of transparent material, and the dust cavity 101b is arranged at one end of the first shell 110' to visualize the dust cavity 101b; the light-blocking piece 840 is of light-blocking material, and is sleeved at the other end of the first shell 110' away from the dust cavity 101b, and the light-blocking piece 840 is provided with a light outlet 841 of the same shape and size as the dust suction port 102, so that when the light assembly 800 emits light, the light is concentratedly emitted from the light outlet 841.

[0444] Specifically, the first mounting assembly 130 and the first shell 110' can both be light-transmitting material, and the light-blocking piece 840 is annular and annularly arranged around the dust suction port 102. By arranging the light-blocking piece 840 around the dust suction port 102 of the dust removal device 10, part of the light emitted by the light-emitting piece 820 can be blocked, so that the light emitted by the light-emitting piece 820 is concentrated in the dust suction range corresponding to the dust suction port 102, without forming a too large light area, and the user can intuitively determine the cleaning area of the dust removal device 10. In addition, the light-blocking piece 840 partially blocks the light emitted by the light-emitting piece 820, which reduces the light intensity entering the user's eyes on the premise of ensuring that the cleaning area is illuminated, thereby protecting the user's eyes and making the use process more comfortable, thereby improving the user experience.

[0445] The first shell 110' is provided with an annular mounting gap 130' on the side close to the dust suction port 102, the light-blocking piece 840 is received and mounted in the mounting gap 130' and is adhesively fixed on the first shell 110', and the edges of the outer contours of the light-blocking piece 840 and the first shell 110' are adaptively fitted to make the outer contours have no obvious gaps. The light-blocking piece 840 is of light-blocking material, for example, of thermoplastic polyurethane elastomer material, which is integrally injection molded during production, has soft and large elasticity, thereby facilitating the user's holding during use, has a good hand feeling, and has superior hardness and wear resistance, and has good oil resistance, chemical resistance, and corrosion resistance, thereby preventing the dust suction port 102 from being easily worn and corroded during use, thereby improving the service life of the dust removal device 10 and improving the user experience.

[0446] In some embodiments, in order to facilitate installation and reduce production costs, the edges of the light-blocking piece 840 are all circular, the shape of the mounting gap 130' on the first shell 110' is matched with the contour of the light-blocking piece 840, but the specific structure of the light-blocking piece 840 is not limited in the present application, and in other embodiments of the present application, the light-blocking piece 840 can be a multi-segment or single-segment ring structure, and the light-blocking piece 840 is installed at the dust suction port 102 of the shell 100 to partially block the light of the light-emitting piece 820, so as to reduce the area of the lighted area and the emitted light.

[0447] In addition, in some embodiments of the present application, the outer side surfaces of the first shell 110' and the light-blocking piece 840 can be embedded with each other through structures such as protrusions and recesses, which on the one hand can increase the area of the light-blocking piece 840 on the first shell 110' to facilitate user holding, and on the other hand can increase the appearance fashion of the dust removal equipment 10. It should be further pointed out that the first shell 110' is provided in a light-transmitting manner to facilitate user observation of the capacity of the cavity 110.

[0448] In order to reduce the installation steps, save production time, and ensure the installation strength of the light-blocking piece 840, the light-blocking piece 840 and the first shell 110' are integrally injection molded by double-color injection molding, so that the light-blocking piece 840 and the first shell 110' are integrally formed, but the present application is not limited thereto, and in other embodiments of the present application, the light-blocking piece 840 can be provided separately from the first shell 110', and the light-blocking piece 840 can be fixed to the mounting gap 130' of the first shell 110' by sleeving and bonding, or in some embodiments of the present application, the light-blocking piece 840 can be fixed to the mounting gap 130' of the first shell 110' by clamping or screwing.

[0449] The technical effect of the above scheme is that through various designs of the shell, the problems of insufficient visualization of the dust cavity and dispersion of light at the dust suction port in the prior art are solved, so that the user can intuitively observe the working state of the device, and the light emitted by the light assembly can be concentrated to irradiate the dust suction port, thereby improving the cleaning effect and user experience.

[0450] Please refer to FIG. 45, in order for the user to effectively use the light to illuminate the dust in the dark, the light assembly 800 specifically includes a circuit board 810 and a light-emitting piece 820. The circuit board 810 is installed in the cavity 101, and the circuit board 810 is coaxially arranged with the dust suction port 102; the light-emitting piece 820 is fixed on the circuit board 810, and the light emitted by the light-emitting piece 820 is emitted towards the dust suction port.

[0451] In some embodiments, in order to simplify the structure of the light assembly 800 and reduce the cost of the dust removal device 10 while being more firmly installed, the light emitting piece 820 is directly welded to the circuit board 810 by welding, in other embodiments, the light emitting piece 820 can also be fixed on the first fixing part 131 by setting the buckle structure, and the electrical connection between the light emitting piece 820 and the circuit board 810 is realized by the wire, or in some embodiments, the light emitting piece 820 can be fixed to the circuit board 810 by plugging and realize the electrical connection between the circuit board 810.

[0452] Among them, the light emitting piece 820 can be an led lamp bead, which is selected to reduce the volume and cost of the light assembly 800, in other embodiments, the light emitting piece 820 can also adopt other types of lamps such as incandescent lamp, fluorescent lamp or laser lamp, which are not limited here.

[0455] In the embodiment of the present application, 6 light emitting pieces 820 are arranged in the form of a circumferential array, which can reduce the size of the light emitting piece 820 in one direction while obtaining more uniform and brighter light, and the dust removal device 10 is in the form of a cylinder, the user can hold the first shell 110 for 360° rotation, and there is no difference in use angle, so the light emitting pieces 820 are arranged in the form of a circumferential array to uniformly emit light, so that the user can hold and use the light at different angles, and the illumination effect can be kept consistent.

[0456] In other embodiments, the light emitting piece 820 can be selected only one, or 2, 4 or 7 or more, which can reach the demand of intensity, and the multiple light emitting pieces 820 can be arranged in a circumferential array or irregularly on the circuit board 810, which is not specifically limited here. For example, the first shell 110 is provided with a holding positioning structure or the first shell 110 is oval-shaped as a whole, and the user holds the first shell 110 at a specific angle when using the dust removal equipment 10, and the light emitting piece 820 can be arranged in a cluster and emitted at a fixed angle from the dust suction port 102.

[0457] Further, the light assembly 800 can further include a baffle 830. Referring to FIG. 46, the baffle 830 is a circular transparent plate structure, and the material of the baffle 830 is transparent polycarbonate. The baffle 830 is arranged on the first fixing portion 131 to enclose the light emitting piece 820 and the circuit board 810, so as to prevent dust from adhering to the light emitting piece 820 during the working process of the dust removal equipment 10, thereby affecting the light intensity of the light emitting piece 820, and the adhesion of dust is easy to affect the electrical connection between the light emitting piece 820 and the circuit board 810. On the other hand, the baffle 830 is made of transparent material, and the light emitting piece 820 can directly pass through the baffle 830, without causing loss to the light intensity.

[0458] The outer diameter of the baffle 830 is the same as the outer diameter of the first fixing portion 131, and the baffle 830 is provided with positioning blocks 831 on both sides of the circular arc. The first fixing portion 131 is provided with positioning grooves (not shown in the figure), the baffle 830 is accommodated in the first fixing portion 131, and the positioning blocks 831 are respectively accommodated in the positioning grooves. The side of the baffle 830 away from the dust suction port 102 is a mounting surface, the mounting surface is attached with an adhesive, and the baffle 830 is bonded to the bottom surface of the positioning groove through the positioning blocks 831, thereby achieving the mounting of the baffle 830 on the first fixing portion 131.

In addition, in some embodiments, the baffle 830 can be arranged without matching the shape of the first fixing portion 131, to partially shield the light emitting piece 820 or through the extension of the arc-shaped baffle 830 structure in the axial direction of the housing 100, such as the baffle 830 being in the shape of a circular ring or a circular conical sidewall, and the two ends of the baffle 830 being connected between the housing 100 and the first fixing portion 131 to block and shield the light emitting piece 820.

[0460] In other embodiments, the positioning grooves can be arranged on the baffle 830, and the positioning blocks 831 can be arranged on the first fixing part 131, or the baffle 830 and the first fixing part 131 are staggered with the positioning grooves and the positioning blocks 831.

[0461] In other embodiments, the baffle 830 can be fixed to the first fixing part 131 by screwing or clamping.

[0462] The above scheme has the technical effect that by integrating the light assembly on the installation assembly, light can be emitted and emitted from the dust suction port to illuminate the area to be cleaned. This design greatly improves the practicality of the cleaning device, enabling the user to clearly observe the area to be cleaned during the cleaning process, making it easier to find hidden dirt and dust, thereby improving cleaning efficiency and accuracy.

[0463] In an embodiment, the portable dust removal device 10 has multiple different cleaning gears, and the light emitted by the light assembly 800 has a light color corresponding to each cleaning gear. In response to a first control instruction triggered by the user for a target cleaning gear, the controller 900 is configured to control the light assembly 800 to emit a first target light with a light color corresponding to the target cleaning gear according to the first control instruction, so that the first target light is emitted from the dust suction port 102.

[0464] Specifically, the portable dust removal device 10 has a multi-gear cleaning function, which can be flexibly adjusted according to the specific needs of cleaning. Different cleaning gears are suitable for keyboard, desktop, carpet, hard floor, furniture and other cleaning scenes, ensuring effective removal of various dust, and each cleaning gear has a corresponding light color, which can intuitively convey the current cleaning state to the user.

[0465] In some embodiments, in response to a first control instruction triggered by the user for a target cleaning gear, the controller 900 adjusts the light assembly 800 to emit a first target light corresponding to the target cleaning gear using the control instruction. The first target light is emitted from the dust suction port 102 of the device, ensuring that the user can see the corresponding light indication at any time during the cleaning process, enhancing the intuitiveness and effectiveness of the cleaning operation.

[0466] In some embodiments, the light assembly 800 is responsible for emitting light colors corresponding to each cleaning gear, and each cleaning gear has a unique light color, so that the user can easily identify the current cleaning mode, thereby better selecting the appropriate cleaning mode. For example, when the first cleaning gear is selected, the light emitting member 820 of the light assembly 800 emits red light, when the second cleaning gear is selected, the light emitting member 820 of the light assembly 800 emits yellow light, and when the third cleaning gear is selected, the light emitting member 820 of the light assembly 800 emits green light, which is not limited in the present application.

[0467] The technical effect of the above scheme is that by integrating multiple cleaning gears and portable dust removal equipment with light prompting function, not only the convenience of user operation and cleaning effect are improved, but also the interactive experience between the user and the equipment during use is improved, so that the dust removal equipment can better meet the demand for intelligence and convenience.

[0468] In another embodiment, the portable dust removal equipment 10 in the present application has multiple different cleaning modes, and the light emitted by the light assembly 800 has a light type corresponding to each cleaning mode. In response to a second control instruction triggered by the user for a target cleaning mode, the controller 900 is configured to control the light assembly 800 to emit a second target light corresponding to the target cleaning mode according to the second control instruction, so that the second target light is emitted from the dust suction port 102.

[0469] Specifically, the portable dust removal equipment 10 has diversified cleaning modes (such as deep cleaning, daily cleaning, meticulous cleaning, etc.), to adapt to different types of cleaning needs. The user can select the appropriate mode according to the specific cleaning task to ensure the best effect.

[0470] In some embodiments, when the user triggers a second control instruction for a target cleaning mode, the controller 900 can receive and process the instruction. According to the second control instruction, the controller controls the light assembly 800 to emit a second target light corresponding to the target cleaning mode, which is emitted from the dust suction port 102 of the equipment, ensuring that the user can see the indicating light during operation, and enhancing the user's understanding of the equipment's working state.

[0471] In some embodiments, the light type of the light assembly 800 corresponds to the cleaning mode, that is, the light assembly 800 can indicate the current cleaning mode by emitting different types of light. Each cleaning mode has a unique light type, for example, blue light indicates deep cleaning, green light indicates daily cleaning, etc., so that the user can intuitively understand the working state of the current equipment through the change of light, and conveniently judge whether the mode needs to be adjusted in time.

[0472] The technical effect of the above scheme is that by introducing multiple cleaning modes and corresponding light feedback mechanisms, the demand of modern families for flexible, convenient and efficient cleaning equipment is successfully met. The indicating light emitted by the device makes the state of the cleaning operation more obvious, and the user obtains more feedback information when using the device, thereby improving work efficiency and satisfaction.

[0473] In an embodiment, the cleaning mode of the portable dust removal device includes at least one of a suction mode, an air charging mode, a vacuum air extraction mode, and a blowing mode, and the light type of the light assembly includes at least one of an LED light, an incandescent lamp, a fluorescent lamp, and a laser light.

[0474] Among them, each cleaning mode has its own characteristics, and users can choose the appropriate mode according to specific cleaning needs to achieve the best cleaning effect. Modern dust removal devices usually combine multiple modes to improve their applicability and efficiency.

[0475] In some embodiments, the light assembly 800 in the dust removal device 10 is used to provide cleaning lighting to better observe and identify dirt during the cleaning process. The characteristics of the several light types mainly include:

[0476] For LED lights (light-emitting diodes), they are excited by electric current to emit light from semiconductor materials. LED lights can be widely used in various dust removal devices, which can provide different colors of light to adapt to different cleaning needs, and consume less power compared to traditional light bulbs, and can be used for tens of thousands of hours, thereby reducing the frequency of replacement.

[0477] For incandescent lamps, they emit light by heating the filament with electric current. Among them, the light emitted by the incandescent lamp is close to natural light, giving people a comfortable feeling, and its purchase cost is relatively low.

[0478] For fluorescent lamps, they emit light by exciting gas to produce ultraviolet light, which irradiates fluorescent powder. Among them, fluorescent lamps are more energy-efficient than incandescent lamps, suitable for long-term use, and can provide more uniform lighting effects.

[0479] For laser lights, they emit highly concentrated and monochromatic light beams through laser diodes. Among them, the light beam of the laser light can be precisely focused, which can provide very strong illumination, suitable for use in environments with insufficient light.

[0480] Among them, different light types in the light assembly 800 have advantages and disadvantages in the dust removal device 10, and users can choose the appropriate light type according to the specific use scenario to improve cleaning efficiency.

[0481] Embodiment Ten

[0482] In portable cleaning devices, users have higher requirements for the convenience, safety and versatility of the device. Traditional cleaning devices rely on basic controls and interfaces, which cannot effectively prevent misoperation and improve cleaning efficiency. Therefore, the present application proposes an improved portable dust removal device, which integrates various control and display components and has a unique design to improve user experience and the intelligent level of the device.

[0483] Please continue to refer to FIG. 1. The portable dust removal device 10 also includes a toggle switch 910, a control switch 920, a display screen 930, filter cotton and a cover assembly (not shown in the figure) installed on the second housing 120.

[0484] In some embodiments, the toggle switch 910 is used to prevent accidental touch and ensure that the device will not be accidentally turned on in a non-use state. Among them, the toggle switch 910 includes two key positions OFF and ON. When the user adjusts the toggle switch 910 to the OFF key position, the user can further control the portable dust removal device 10 through the control switch 920. When the user adjusts the toggle switch 910 to the ON key position, the portable dust removal device 10 cannot respond to the user's control operation on the control switch 920. Therefore, the design of this switch considers the naturalness and convenience of user operation, so that the user does not need to worry about accidental pressing when picking up the device, avoiding unnecessary energy consumption and potential danger.

[0485] In some embodiments, the control switch 920 is mainly used to control the opening, closing and adjustment of the suction force position of the portable dust removal device 10. Through a unique control design, the switch allows the user to quickly switch the suction force position and turn on / off the device to adapt to different operation purposes, thereby providing a more flexible solution. For example, when the user long-presses the control switch 920 for more than 5 seconds, the portable dust removal device 10 will switch from the on state to the off state, or from the off state to the on state; when the user point-presses the control switch 920, the portable dust removal device 10 will switch from the current level of suction force position to the next level of suction force position; or; when the user continuously point-presses the control switch 920, the display content on the display screen 930 will adaptively change to show the corresponding display content to the user.

[0486] In some embodiments, the display screen 930 is used to display the power, current position and design logo of the device in real time. In this way, through clear visual feedback, the user can quickly obtain the working state of the device.

[0487] In some embodiments, the filter cotton is installed in the second housing 120 near the air outlet 103, which in one aspect is used for the last purification of the air to be discharged to the environment to effectively capture tiny particulate matter, dust and other pollutants in the air, ensuring that the discharged air is fresh and clean, thereby ensuring that the environment is not secondarily polluted during the cleaning process, thereby improving the user's experience; in another aspect, it is used to shield the structure and components inside the housing to achieve the purpose of beautifying the dust removal equipment 10, so that the user will not see the internal circuit, pipeline and other structures when using the equipment, thereby improving the overall visual effect of the equipment and making it more in line with the aesthetic needs of modern homes.

[0488] In some embodiments, the cover assembly not only serves to store and protect the cleaning accessory 200, but can also be designed as a wired / wireless charging base or charging compartment to automatically charge the portable dust removal equipment 10 after the cleaning accessory 200 is placed in the cover assembly, eliminating the need to install a charging interface on the main machine shell or for the user to charge the battery separately. In addition, some related multifunctional designs can also be configured inside the assembly. For example, some cleaning materials are placed inside the cover, so that when the brush head is placed back in the cover, the internal cleaning materials can be used to clean the brush head, eliminating the need for the user to clean the tool separately, greatly improving the convenience and maintenance efficiency of the cleaning equipment.

[0489] In other embodiments, the portable dust removal equipment 10 can also be configured with various cleaning accessories 200 that are matched with dust removal pens to cope with various use scenarios, such as flat mouth suction heads, long hose suction nozzles, pointed mouth suction heads, two-in-one / three-in-one suction heads, etc.; and the cleaning accessory 200 can also be configured with additional functions such as air inflation, vacuum air suction and air blowing in addition to the dust removal and suction functions.

[0490] The technical effect of the above scheme is that the portable dust removal equipment provides a safe, convenient and intelligent cleaning solution by integrating the toggle switch, control switch, display screen and cover assembly. This design not only improves the safety and convenience of user operation, but also realizes the diversification and intelligentization of device functions, and has good market application prospects and potential.

[0491] Embodiment Eleven

[0492] With the continuous progress of technology, smart home devices have gradually become an important part of modern living environments. Users' expectations for cleaning equipment are not limited to basic cleaning functions, but also hope to improve the convenience and operation experience through intelligent control methods. Therefore, the present application proposes a portable dust removal equipment 10 that integrates various control modules to achieve comprehensive intelligent control and meet the diverse needs of users.

[0493] As an implementation, the portable dust removal device 10 includes a manual switch module, a touch control module, a voice module, a networking module, a wireless module, and an atomization module, which are connected with an intelligent control system (not shown in the figure) respectively.

[0494] In some embodiments, the manual switch module can be a key switch or an encoder, the touch control module can be a touch key, a slide resistor, a touch slide module, or a touch screen module, and the wireless module can be a mobile control module, a Bluetooth control module, and a wireless control module.

[0495] Among them, the key switch can realize manual control of the portable dust removal device 10, and the opening, closing, and speed regulation of the portable dust removal device 10 are realized by pressing the button. The encoder is used to adjust the wind speed, and the setting of the rotating speed of the portable dust removal device 10 is changed by rotating the encoder. The touch key controls the switch and wind speed adjustment of the portable dust removal device 10 through touch sensing. The slide resistor can realize the adjustment of the wind speed by adjusting the resistance value through sliding, and provides continuous wind speed adjustment. The touch slide module adjusts the wind speed through a sliding gesture, detects sliding parameters such as speed, direction, and position to control the wind speed. The touch screen module provides a graphical interface, and various functions such as switching, wind speed adjustment, timing setting, etc. are realized through the touch screen. The voice control module can realize the opening, closing, and wind speed adjustment of the portable dust removal device 10 through voice instructions, and improve the intelligent control experience. The networking voice control module can realize the uploading of voice instructions to the cloud server for processing through internet connection, and realize remote voice control. The networking module can realize remote control function through the internet, and can remotely control various functions of the portable dust removal device 10 through a mobile phone or other devices. The mobile control module can realize the control of various functions of the portable dust removal device 10, including switching, wind speed adjustment, timing, etc. through a mobile device (such as a mobile phone or a tablet). The Bluetooth control module can realize the connection of a mobile device through Bluetooth, and realize the wireless control of the fan in a short distance. The wireless control module can realize the remote control and management of the portable dust removal device 10 through wireless signals (such as Wi-Fi). The atomization module can realize the provision of humidification function, and the wind blown by the portable dust removal device 10 is more cool and moist through atomized water.
