The first shell and the second shell are both pre-configured shells in the portable dust removal device, but they are not shells of the same scope.

[0070] In order to explain the technical content, technical steps, objectives and effects of this application in detail, the following is a detailed description in combination with the implementation methods and the accompanying drawings.

[0071] Example 1

[0072] In today's fast-paced world, the demand for portable cleaning tools is increasing. Users want to be able to perform simple and efficient cleaning anytime, anywhere, but traditional cleaning equipment is often bulky and difficult to carry. The portable dust removal device 10 of the present application, through its miniaturized design, meets users' dual needs for cleaning efficiency and portability.

[0073] like Figure 1 and Figure 2 As shown, the portable dust removal device 10 includes: a housing 100, a cleaning accessory 200, a driving source 300, a filter assembly 400, and an air pressure assembly 500. The housing 100 is a handheld mini housing, having a cavity 101 inside the housing 100, and a dust suction port 102 connected to the outside world is provided at one end of the cavity 101; the cleaning accessory 200 is disposed in the cavity 101 and at least partially extends out of the dust suction port 102; the driving source 300 is disposed in the cavity 101 and is used to drive the cleaning accessory 200 to move so as to clean the surface to be cleaned near the dust suction port 102 through the cleaning accessory 200; the air pressure assembly 500 is disposed in the cavity 101 and is used to generate air pressure in the cavity 101 so that the garbage on the surface to be cleaned is sucked into the cavity 101 through the dust suction port 102; and the filter assembly 400 is used to filter the garbage sucked into the cavity 101.

[0074] Specifically, the housing 100 of the portable dust removal device 10 is a user-friendly handheld mini housing, which is carefully designed in structure to be compact and easy to carry. The housing 100 is provided with a cavity 101 for cleaning, which constitutes the basic framework of the dust removal device 10.

[0075] In some embodiments, as Figure 1 As shown, the appearance of the portable dust removal device 10 is mainly presented by the shell 100. In order to facilitate the user to hold it, the shell 100 can be in the shape of a slender cylindrical shell structure, and its size is also more miniaturized than the existing dust removal equipment, with a diameter of about 2.5 cm and a length of about 15 cm. That is, the shape and size of the portable dust removal device 10 are slightly close to the pen used in daily life, which is conducive to the user holding and using this small and precise cleaning device.

[0076] In some embodiments, the housing 100 is a hollow structure, that is, a cavity 101 is provided within the housing 100. A dust suction port 102 connected to the outside world is provided at one end of the cavity 101, and an air outlet 103 connected to the outside world is provided at the other end. The dust suction port 102 is located near the surface to be cleaned and is used to suck in dust swept off the surface to be cleaned. 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 miniature design of the cavity 101 ensures the flexibility of the device during use.

[0077] Among them, the specific shape and size of the shell 100 only need to be easy for the user to hold and more miniaturized than the existing device. No specific limitation is made to it 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 cylindrical shape with a larger diameter, and its specific size can also be other values.

[0078] In some embodiments, as Figure 2 As shown, the portable dust removal device 10 of the present application achieves 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 accessories 200, the driving source 300, the wind pressure component 500, the filter component 400 and other components of the portable dust removal device 10 (for example, batteries, air guide covers, etc.) that are customized in shape and size can be combined together in sequence to form a complete portable dust removal device 10. Among them, the cleaning accessories 200, the driving source 300, the wind pressure component 500 and the filter component 400 are connected in series in the cavity 101 to form a compact and efficient cleaning system, so that powerful cleaning performance can be achieved without taking up too much space.

[0079] In some embodiments, each component of the portable dust removal device 10 is detachably connected to the housing 100 or other components, thereby making the assembly and subsequent disassembly of the components more convenient and more efficient.

[0080] In some embodiments, one end of the cleaning accessory 200 is an installation end, which is used to be installed on the output shaft of the driving source 300 to realize power transmission between the cleaning accessory 200 and the driving source 300; the other end is a cleaning end, which is used to clean the surface to be cleaned under the drive of the driving source 300.

[0081] 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 the user can also replace the corresponding cleaning accessory 200 for cleaning different types of surfaces to be cleaned, so as to effectively clean the surface to be cleaned. Therefore, the cleaning accessory 200 is exquisitely designed and can flexibly meet the cleaning needs of different surfaces and environments.

[0082] In one embodiment, in order to ensure the strength of the mounting end of the cleaning accessory 200 and prevent the excessively long mounting end and the output shaft from being deformed or damaged when subjected to force, the cleaning accessory 200 can be arranged in a manner that partially extends from the dust suction port 102 to the cavity 101, but in other embodiments, the mounting end can also be arranged not to extend into the dust suction port 102, that is, the cleaning accessory 200 is arranged to extend entirely from the dust suction port 102, in which case part of the output shaft extends from the dust suction port 102, and the mounting end and the output shaft are fixedly assembled.

[0083] In some embodiments, the drive source 300 is installed in the cavity 101 and is arranged behind the cleaning accessory 200. It is responsible for driving the movement of the cleaning accessory 200 to achieve the cleaning ability of the device. The drive source 300 is a detachable and replaceable drive motor. The type of drive motor includes a rotary motor, a vibration motor, or an ultrasonic generator.

[0084] For example, the driving source 300 may be a rotary motor that drives the cleaning accessory to rotate and clean the surface to be cleaned. The rotary motor can be used to clean oil stains or fingerprints on a surface. It can provide smooth rotational power to the cleaning accessory 200, allowing the cleaning accessory 200 to effectively contact the cleaning surface, thereby efficiently removing attached stains without damaging the surface.

[0085] For another example, the driving source 300 may be a vibration motor, which is used to drive the cleaning accessory by vibration, so that the cleaning accessory vibrates and cleans the surface to be cleaned. The vibration motor can be used to clean dust attached to the surface. The subtle vibration generated by the vibration motor can effectively loosen and shake off the dust attached to the surface, thereby enhancing the cleaning effect, especially when cleaning fabrics or uneven surfaces.

[0086] For some specific scenarios, such as deep cleaning of stubborn stains or fine particles, the driving source 300 can be an ultrasonic generator, so as to achieve a deep cleaning effect on the cleaning surface through the high-frequency sound waves generated by the ultrasonic generator.

[0087] Among them, the use of multiple options of rotating motors, vibrating motors and ultrasonic generating devices enables the driving source 300 to provide the best solution under different cleaning needs, thereby meeting the cleaning requirements in home, industrial and special environments.

[0088] In some embodiments, the wind pressure component 500 is located in the cavity 101 and is arranged behind the filter component 400. It is used to generate wind pressure in the cavity 101. Its function is to suck the garbage on the surface to be cleaned into the cavity 101 through the suction port. This function is effectively implemented in the mini space, enhancing the dust suction ability of the equipment.

[0089] Among them, the wind pressure component 500 may include a motor and a fan blade. The motor is fixedly installed on the shell 100 and accommodated in the cavity 101. The fan blade is mounted on the power shaft of the motor, so that the motor can drive the fan blade to rotate, thereby generating wind 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.

[0090] In some embodiments, the filter component 400 is arranged in the cavity in sequence and is located between the wind pressure component 500 and the driving source 300. Its function is to effectively filter the garbage entering the cavity 101 to ensure the cleaning effect, while preventing the garbage from flowing back into the environment, thereby improving the safety of user use.

[0091] Among them, the material of the filter component 400 can be a microporous ceramic filter mesh for filtering larger particles of dust; and / or a metal mesh, which has low cost and good filtering effect; and / or a sponge filter layer to filter out larger substances in the air; and / or a HEPA filter layer to filter out particles with a smaller radius, and the filtering effect is better when used together.

[0092] In a specific implementation scenario, when the portable dust removal device 10 is working, the driving source 300 first drives the cleaning accessory 200 to move so that the cleaning accessory 200 sweeps off the garbage on the surface to be cleaned; then the wind pressure component 500 drives the fan blades to rotate, thereby generating wind pressure in the cavity 101 to suck the garbage on the surface to be cleaned into the cavity 101 through the dust suction port 102; finally, the filter component 400 filters the air carrying garbage in the suction cavity 101 to discharge the filtered clean air from the air outlet 103.

[0093] As a specific embodiment, the portable dust removal device 10 at least includes a handheld dust removal pen for wireless handheld use and an automatic dust removal device for automatic opening and closing and dust collection.

[0094] The handheld dust removal pen features a wireless design, making it lightweight and portable, suitable for handheld use. Its ergonomic design allows for extended holding while cleaning, reducing fatigue. The pen is ideal for cleaning dust and dirt on desks, keyboards, windowsills, and other confined areas. Its wireless design allows users to move it freely, enhancing convenience and flexibility.

[0095] The automatic dust collector features an intelligent on / off function, autonomously cleaning a pre-set fixed area according to a preset operating mode. It can be remotely controlled by the user or automatically turned on or off based on environmental conditions, enhancing user convenience. Furthermore, the dust collector can connect to the user's other smart devices for remote control and scheduled cleaning.

[0096] The technical effect of the above solution is that the device not only avoids the bulkiness and inconvenience of traditional cleaning tools, but also provides a portable, flexible and efficient solution that meets the expectations of modern users for portable cleaning devices. Users can easily carry the device in every corner of their daily lives and clean at any time, improving their quality of life. Specifically, on the one hand, by differentiating from the existing technology, a handheld mini shell is used to store the cleaning accessories, drive source, wind pressure component and filter component in the cavity, which greatly reduces the physical volume of the dust removal device and realizes the miniaturization of the dust removal device, thereby improving the portability and operability of the dust removal device; on the other hand, this solution first uses the drive source to drive the cleaning accessories to clean the surface to be cleaned near the suction port, and then uses the wind pressure component to generate wind pressure in the cavity to suck the garbage on the surface to be cleaned into the cavity through the suction port, and finally uses the filter component in the cavity to filter the sucked garbage, thereby achieving the cleaning of dirt such as dust and garbage, effectively improving the cleanliness of dirt in dead corners and gaps, thereby achieving powerful cleaning.

[0097] Those skilled in the art will understand that Figure 1 and Figure 2 The structure of the portable dust removal device shown in the figure is only a block diagram of a part of the structure related to the solution of the present application, and does not constitute a limitation on the portable dust removal device to which the solution of the present application is applied. The specific portable dust removal device may include more or fewer components than shown in the figure, or combine certain components, or have a different component arrangement.

[0098] Example 2

[0099] In the application of portable cleaning equipment, how to effectively separate garbage from purified air and improve cleaning efficiency is a key challenge. Traditional designs often cannot effectively distinguish impurities from clean airflow, resulting in limited cleaning effectiveness of the equipment. This application provides a new portable dust removal device 10 by optimizing the housing structure, which can effectively solve this problem.

[0100] Please continue reading Figure 1 and Figure 2 For the housing 100 in the above embodiment, the housing 100 also includes a detachable first shell 110 and a second shell 120. The first shell 110 and the second shell 120 together enclose a cavity 101, and the dust suction port 102 is provided at one end of the first shell 110 away from the second shell 120; wherein, the 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.

[0101] Specifically, the housing 100 comprises a detachable first shell 110 and a second shell 120, which together enclose a cavity 101. This structural design aims to improve the maintainability and operational convenience of the device, while also making it easier for users to clean and maintain it after disassembly.

[0102] Furthermore, inside the chamber 101, a filter assembly 400 is installed in the first housing 110, which divides the chamber 101 into two areas: the installation chamber 101a and the dust chamber 101b. This design makes the flow of air inside the device more orderly and can effectively separate impurities from clean air.

[0103] Furthermore, the dust suction port 102 is located at the end of the first housing 110 away from the second housing 120 to ensure that dirt and garbage are quickly sucked in during the cleaning process. At the same time, clean airflow passing through the filter assembly 400 is formed within the installation cavity 101a and finally discharged through the air outlet 103, ensuring that the released air is clean and pollution-free.

[0104] The separating action of filter assembly 400 optimizes the direction of airflow, allowing debris on the surface to be cleaned to quickly enter dust chamber 101b after being drawn into chamber 101 through suction port 102. This design effectively captures and stores impurities, significantly reducing the risk of them being recirculated into the environment. Meanwhile, the filtered, clean airflow is smoothly discharged through mounting chamber 101a to the air outlet, improving overall cleaning efficiency.

[0105] In some embodiments, the first shell 110 and the second shell 120 are both slender cylindrical structures with a diameter of 2.5 cm. The first shell 110 and the second shell 120 are fixed together by screws. In the assembled state, the length of the housing 100 is approximately 15 cm. The dust chamber 101b and the dust suction port 102 inside the shell are connected and coaxially arranged. The installation chamber 101a and the dust chamber 101b have the same cylindrical cross-sectional shape, while the dust suction port 102 has a circular cross-sectional shape.

[0106] The cross-sections of the mounting cavity 101a, the dust cavity 101b, and the dust suction port 102 are circular in order to achieve uniform suction, maintain a consistent and beautiful appearance, and maintain a consistent thickness of the housing 100. However, the specific shapes of the mounting cavity 101a, the dust cavity 101b, and the dust suction port 102 can also be other styles. For example, the cross-sections of the mounting cavity 101a and the dust cavity 101b can also be elliptical or polygonal, the cross-section of the dust suction port 102 can be waist-shaped or rectangular, 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 snapping or plugging, or opened and closed by a rotating shaft connection and a locking structure, which is not specifically limited here.

[0107] In addition, in the embodiment of the present application, the airflow direction refers to the direction in which the gas flows in the cavity 101, and the airflow direction is roughly the axial direction of the first shell 110 and the second shell 120. It will be slightly offset in the radial direction of the cavity 101 due to the blocking effect of the wind guide structure and internal parts at some positions of the cavity 101, and the airflow direction described when limiting the direction refers to the axial direction of the first shell 110 and the second shell 120, and the outer contour of the first shell 110 and the second shell 120 is cylindrical, and its axis is the central axis of the corresponding cylinder.

[0108] The technical effect of the above solution is that: by designing the cavity of the shell to be divided into an installation cavity and a dust cavity, more efficient garbage separation and airflow optimization are achieved. After the clean 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, which not only optimizes the cleaning effect, but also greatly improves the user experience. In summary, the portable dust removal device of the present application significantly improves the cleaning efficiency and airflow management capabilities through the unique shell structure design, which can meet the multiple demands of modern users for the efficiency and convenience of cleaning equipment.

[0109] Example 3

[0110] In modern cleaning equipment, the way the cleaning parts are cleaned is crucial to their effectiveness. Traditional cleaning accessories often lack efficient drive mechanisms, resulting in unstable movement during the cleaning process, affecting cleaning quality and efficiency. Therefore, a new type of cleaning accessory is urgently needed that utilizes an efficient output shaft drive design to achieve efficient cleaning of the surface being cleaned.

[0111] See also Figure 3 and Figure 4For the cleaning accessory 200 in the above embodiment, the cleaning accessory 200 includes 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 cleans the surface to be cleaned in a moving manner under the drive of the output shaft 310.

[0112] In some embodiments, a mounting shaft 212 having a regular hexagonal cross-section is provided on the side of the base 210 facing away from the cleaning portion 220, and a regular hexagonal mounting hole is also provided on the corresponding output shaft 310 of the driving source 300 (not shown in the figure). The mounting shaft 212 is installed on the output shaft 310 in a plug-in manner to realize power transmission between the cleaning accessory 200 and the first driving source 300, thereby ensuring that the cleaning accessory 200 can operate stably while withstanding the force brought by the dynamics.

[0113] In some embodiments, the mounting shaft 212 can be made of magnetic material, and the end of the output shaft 310 of the driving source 300 is also provided with magnetic material, and the magnetism of the two is opposite. While the cleaning accessory 200 is installed by plug-in, it can also be detachably installed by magnetic attraction. Compared with the tight-fitting plug-in installation method, the installation and disassembly process of the magnetic assembly is more labor-saving and easy, and there is a sense of being fully assembled.

[0114] In some embodiments, the base 210 can be a solid cylindrical ring structure, 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 the dust suction port 102, and the air flow carrying impurities is sucked into the dust suction port 102 from the outside of the circumference of the base 210.

[0115] The base 210 is designed to be a solid cylindrical ring structure, which provides excellent stability and load-bearing capacity, capable of withstanding the kinetic energy during cleaning, while also facilitating connection to the vacuum system. Furthermore, the diameter of the base 210 is designed to be smaller than that of the suction port 102, allowing the base 210 to effectively integrate with the suction port 102, ensuring a smooth airflow path and providing favorable conditions for subsequent vacuuming.

[0116] The technical effect of the above solution is that by setting the cleaning part 220 to be fixed to the base 210, it is ensured that it will not be displaced or fall off during the movement, so that the cleaning part 220 is driven by the output shaft 310 of the driving source 300 and effectively cleans the surface to be cleaned in a moving manner.

[0117] Further, see Figure 5The cleaning portion 220 may be cleaning bristles, and the cleaning bristle array is distributed on the root of the base 210, wherein the base 210 is provided with an installation enclosure 211 on one side where the cleaning bristles are installed, and the installation enclosure 211 is used to partially enclose the cleaning bristles.

[0118] The design of the mounting enclosure 211 is intended to limit the movement of the cleaning bristles within its enclosure. This measure ensures that the bristles have a clear range of motion during the cleaning process, preventing excessive movement that could cause bristle failure or missed cleaning areas. Furthermore, the cleaning bristles possess excellent flexibility and adaptability, effectively cleaning impurities and dirt from various surfaces. Furthermore, the array of cleaning bristles at the base of the base 210 ensures even distribution, providing a larger contact area and thus improving cleaning effectiveness.

[0119] In another embodiment, please refer to Figure 5 The cleaning portion 220 may be cleaning bristles, and the cleaning bristle array is distributed 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 plugged and installed 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.

[0120] The rotatable mounting shaft 212 allows the cleaning bristles to flexibly move within a specific angle range, adapting to the cleaning needs of different surface shapes and angles. This design makes the cleaning action more efficient and better able to remove dirt and debris. In addition, by adjusting the angle of the bristles' movement, the cleaning unit 220 can demonstrate greater adaptability to different cleaning conditions. This means that even on complex surface structures, the cleaning bristles can achieve a deeper cleaning effect.

[0121] In other embodiments, the type of the cleaning accessory 200 is removable and replaceable, and the types of the cleaning accessory 200 include a first type of cleaning accessory in which the cleaning part 220 is suede or a second type of cleaning accessory in which the cleaning part 220 is a brush, wherein the suede is used to clean oil stains or fingerprints on the surface, and the brush is used to clean dust attachments on the surface.

[0122] In some embodiments, users can select and replace different cleaning accessories 200 according to their cleaning needs. The suede-type cleaning unit 220, leveraging the unique texture and softness of suede, effectively removes stains without damaging the surface being cleaned. The brush-type cleaning unit 220, with its stiffness and dense bristle layout, can quickly and effectively collect and remove particles from surfaces when sweeping dust.

[0123] The technical effect of the above solution is that by setting an installation enclosure or a movable installation shaft at the base, the active area of the cleaning bristles is effectively limited, thereby improving the cleaning effect and the durability of the bristles. This innovative design not only ensures effective coverage of the cleaning action, but also provides users with a more convenient operation experience. In addition, the detachable and replaceable design of the cleaning accessories, combined with different types of cleaning parts, can effectively meet various cleaning needs. Whether it is suede for oil stains and fingerprints, or a brush specifically for removing dust attachments, it can provide the best cleaning effect in different scenarios.

[0124] See also Figure 6 and Figure 7 In another embodiment of the present application, a cleaning accessory 200 ′ is further provided. The cleaning accessory 200 ′ includes a base 210 ′ and a cleaning portion 220 ′. The cleaning portion 220 ′ is fixed to the base 210 ′.

[0125] In some embodiments, as Figure 6 and Figure 7 As shown, the above-mentioned base 210' includes a first base 211', a connecting body 212' and a second base 213' connected in sequence, wherein the first base 211' is a cylindrical ring structure, and the first base 211' is coaxially provided with a cylindrical suction hole 211a', the second base 213' is a cylindrical structure, and the outer contour diameter of the second base 213' is smaller than the outer contour diameter of the first base 211', and the second base 213' is provided with a mounting shaft 213a' on the side away from the first base 211', the connecting body 212' is a rod structure, and the connecting body 212' is arranged at an angle of 20° to the axis of the first base 211', the number of the connecting bodies 212' is 3, and the 3 connecting bodies 212' are arranged in a circular array around the axis of the first base 211', one end of the connecting body 212' is connected to the first base 211', and the other end is connected to the second base 213'.

[0126] When the user activates the cleaning accessory 200', the garbage swept by the cleaning portion 220' is first sucked in through the suction hole 211a' of the first base 211', then around the side of the second base 213' and sucked into the dust suction port 102. In some embodiments, the structure of the base 210' facilitates the suction of the swept garbage into the dust removal device 10. The garbage does not need to be sucked around the outside of the first base 211' and then into the dust chamber 101b. Because the outside of the first base 211' is away from the dust suction port 102, the suction force there is weaker, making it difficult for the garbage to be sucked into the dust chamber 101b.

[0127] Among them, the outer contours of the first base 211', the second base 213' and the suction hole 211a' are all set to be cylindrical so that the cleaning accessory 200' can run more smoothly during the rotation cleaning process, and the dust removal equipment 10 has a more balanced suction force when sucking in the garbage swept down by the cleaning accessory 200'. In other embodiments, the outer contours of the first base 211', the second base 213' and the suction hole 211a' can also be elliptical or polygonal such as a triangle, rectangle, hexagon, etc., which are not specifically limited here.

[0128] Among them, the connecting body 212' is set at an angle of 20° with the axis of the first base 211' in order to ensure the connection strength between the first base 211' and the second base 213', that is, to reduce the outer diameter of the second base 213' and reasonably avoid the air flow channel. In other embodiments, the angle between the connecting body 212' and the axis of the first base 211' can also be 35°, 40° or 53°, etc., or in some embodiments, the outer diameters of the first base 211' and the second base 213' are the same. At this time, the connecting body 212' can be set perpendicular to the first base 211', that is, the angle between the axis of the connecting body 212' and the first base 211' is 0°.

[0129] Among them, the number of connectors 212' is 3 for the overall strength of the base 210' and to avoid space in the air flow channel. In other embodiments, the number of connectors 212' can also be 2 or 5 or more. Multiple connectors 212' are distributed in a circular array around the axis of the first base 211', or while ensuring the connection strength between the first base 211' and the second base 213', the number of connectors 212' can be set to only 1.

[0130] In some embodiments, the cleaning portion 220' is a cylindrical ring structure, the cleaning portion 220' is suede, the cleaning portion 220' is fixed to the first base 211', and the cleaning portion 220' does not block the suction hole 211a'. In particular, according to the characteristics of suede and microfiber synthetic leather having relatively fine surface fibers, the cleaning portion 220' can absorb oil while cleaning the surface to be cleaned, so that the user can remove garbage in the area to be cleaned when using the dust removal equipment 10, and can also wipe off oil or fingerprints on the surface to be cleaned, so that the user does not need to clean the oil twice, the operation is convenient, and the cleaning ability is strong. In addition, in addition to suede, the specific material of the cleaning portion 220', for example, in other embodiments, the cleaning portion 220' can also be made of microfiber synthetic leather or other materials with a certain hardness and wear resistance, and can absorb grease.

[0131] In some embodiments, as Figure 7As shown, 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 213' away from the first base 211'. Because when the cleaning accessory 200' is installed on the first shell 110, the base 210' is partially accommodated in the dust chamber 101b. When installing the cleaning accessory 200', the installation shaft 213a' on the first base 211' needs to be extended from the dust suction port 102 into the dust chamber 101b. The provision of the installation chamfer 213b' facilitates the central alignment of the cleaning accessory 200' during installation, thereby facilitating the user's disassembly and replacement, thereby improving the user experience. The installation shaft 213a' is also similarly provided with an assembly chamfer 213a1', which has a similar function to that of the above-mentioned installation chamfer 213b' and is not further described here.

[0132] See also Figure 8 In another embodiment of the present application, a cleaning accessory 200" is further provided. The cleaning accessory 200" includes a base 210" and a cleaning portion 220". Among them, for the above-mentioned base 210", the base 210" includes a first base 211", a connecting body 212" and a second base 213" connected in sequence. The first base 211" is a cylindrical ring structure, the cleaning portion 220" is a bristle, and the cleaning portion 220" is fixed on the first base 211". The first base 211" is coaxially provided with a cylindrical suction hole 211a". The second base 213" is a cylindrical structure, and the outer contour diameter of the second base 213" is smaller than that of the first base 2 11" outer contour diameter, a mounting shaft 213a" is provided on the side of the second base 213" facing away from the first base 211", and the connecting body 212" is a rod structure, and the connecting body 212" is set at an angle of 20° to the axis of the first base 211", the number of the connecting bodies 212" is 3, and the 3 connecting bodies 212" are arranged in a circular array around the axis of the first base 211", and one end of the connecting body 212" is connected to the first base 211", and the other end is connected to the second base 213".

[0133] When the user uses it, after starting the cleaning accessory 200", the garbage swept by the cleaning part is first sucked in through the suction hole 211a" of the first base 211", and then goes around the side of the second base 213" and is sucked into the dust suction port 102. In some embodiments, the structure of the base 210" is set to facilitate the suction of the swept garbage into the dust removal device 10. The garbage does not need to go around the outside of the first base 211" and then be sucked into the dust chamber 101b. Because the outside of the first base 211" deviates from the dust suction port 102, the suction force here is relatively small, and the garbage is not easily sucked into the dust chamber 101b.

[0134] Among them, the outer contours of the first base 211", the second base 213" and the suction hole 211a" are all set to be cylindrical so that the cleaning accessory 200" can run more smoothly during the rotation cleaning process, and the dust removal equipment 10 has a more balanced suction force when sucking in the garbage swept by the cleaning accessory 200". In other embodiments, the outer contours of the first base 211", the second base 213" and the suction hole 211a" can also be elliptical or polygonal such as triangle, rectangle, hexagon, etc., which are not specifically limited here.

[0135] Among them, the connecting body 212" is set at an angle of 20° with the axis of the first base 211" in order to ensure the connection strength between the first base 211" and the second base 213", that is, to reduce the outer diameter of the second base 213", and to reasonably avoid the air flow channel. In other embodiments, the angle between the connecting body 212" and the axis of the first base 211" can also be 35°, 40° or 53°, etc., or in some embodiments, the outer diameters of the first base 211" and the second base 213" are the same. At this time, the connecting body 212" can be set perpendicular to the first base 211", that is, the angle between the axis of the connecting body 212" and the first base 211" is 0°, which is not specifically limited here.

[0136] Among them, the number of connectors 212" is 3 for the overall strength of the base 210" and to avoid space in the air flow channel. In other embodiments, the number of connectors 212" can also be 2 or 5 or more. Multiple connectors 212" are distributed in a circular array around the axis of the first base 211", or while ensuring the connection strength between the first base 211" and the second base 213", the number of connectors 212" can be set to only 1.

[0137] Further, see Figure 9 and Figure 10 A storage chamber 211c1" may be provided in the base 210 of various cleaning accessories 200 of the present application. The storage chamber 211c1" is used to store cleaning materials, and the storage chamber 211c1" has a powder outlet 211b1" connected to the outside. When the cleaning accessory 200 moves, the movement path of the powder outlet 211b1" and the movement path of the cleaning portion 220 at least partially overlap.

[0138] For example, with respect to the above-mentioned first base 211", the first base 211" is provided with a hair implant 211b" and a material storage part 211c", wherein the hair implant 211b" and the material storage part 211c" are both annular columnar structures, and their cross-sectional profile shapes and sizes are the same, and the hair implant 211b" and the material storage part 211c" are detachably installed by screwing.

[0139] Specifically, if Figure 9As shown, the cleaning part 220" can be fixed on the bristle implant 211b", and multiple cleaning parts 220" are arranged in an array to form a cylindrical bristle group 221". The cleaning accessory 200" has 5 bristle groups 221". The 5 bristle groups 221" are fixed on the bristle implant 211b" in a circular array around the axis of the bristle implant 211b". The cleaning parts 220" are arranged in clusters and at intervals to facilitate the dust removal equipment 10 to suck in the garbage on the surface to be cleaned, and the garbage is not easily stuck between the cleaning parts 220". In the case of the same number of cleaning parts 220", the cleaning part 220" is arranged in a single cluster to reduce the cross-sectional area of the bristle group 221", and it is also easier for users to clean the garbage attached to the cleaning part 220".

[0140] Among them, in other embodiments, the number of bristle groups 221" can be 2, 3 or 7 or more, and multiple bristle groups 221" are fixed on the bristle implant 211b" in a circular array around the axis of the bristle implant 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.

[0141] Specifically, see Figure 10 and Figure 11 A storage chamber 211c1" is provided in the storage piece 211c", and the storage chamber 211c1" has an opening 211c11" on the side facing the bristle implant 211b". The bristle implant 211b" can block the opening 211c11" when it is installed on the storage piece 211c". The storage chamber 211c1" is used to store cleaning materials, such as carbon powder, talcum powder or fluff powder, etc., which can absorb grease. Correspondingly, the bristle implant 211b" is provided with 5 cylindrical powder outlet holes 211b1" connected to the outside world. The 5 powder outlet holes 211b1" are distributed in a circular array around the axis of the bristle implant 211b". The powder outlet holes 211b1" and the bristle group 221" are distributed at intervals and are located on a circular contour line of the same diameter, and the cross-sectional diameter of the powder outlet holes 211b1" is the same as the cross-sectional diameter of the bristle group 221".

[0142] Among them, by setting up the storage chamber 211c1" in the base 210 as mentioned above for storing various suitable cleaning materials, this design provides a built-in storage space, avoiding the complexity of external material storage, and the storage chamber 211c1" has a powder outlet hole 211b1" connected to the outside world, allowing the cleaning material to be quickly released to the surface to be cleaned when needed.

[0143] Among them, see Figure 12, the setting of the material storage part 211c" allows the user to release cleaning powder through the powder outlet 211b1" to assist cleaning while cleaning the surface to be cleaned, thereby improving the user experience. In addition, the powder outlet 211b1" and the bristle group 221" are located on a circular contour line of the same diameter. When the cleaning accessory 200" is rotating for cleaning, the movement path of the powder outlet 211b1" and the movement path of the cleaning part 220 at least partially overlap, that is, the position where the powder outlet 211b1" discharges the powder and the movement trajectory of the cleaning part 220" overlap. 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 spread the cleaning powder on the cleaned surface. Through the above-mentioned design, during the cleaning process, the released cleaning material can accurately fall on the surface being cleaned, thereby improving the efficiency of the use of the cleaning material and ensuring that the cleaning effect can be maximized every time cleaning.

[0144] In other embodiments, the cleaning accessory 200" can also be used in other scenarios where powder needs to be applied to the work area, such as applying water-absorbing magnesium powder to the work area. In addition, the powder outlet holes 211b1" are arranged in a cylindrical shape and in a number of 5 and the brush groups 221" are evenly spaced to make the powder output of the cleaning accessory 200" more uniform, and the brush group 221" can also evenly spread the cleaning powder onto the surface to be cleaned.

[0145] Furthermore, in order to control the amount of powder output from the powder outlet 211b1", a non-woven fabric (not shown) is provided at the position of the bristle implant 211b" corresponding to the powder outlet 211b1". The non-woven fabric is bonded to the side of the bristle implant 211b" facing the storage part 211c". The non-woven fabric is used to block the powder in the storage cavity 211c1" from being released directly from the powder outlet 211b1", so that the user cannot control the amount of powder output, thereby causing waste or secondary garbage requiring additional cleaning. The setting of the non-woven fabric prevents the powder in the storage cavity 211c1" from being released directly from the powder outlet 211b1" in the absence of external force. When the user needs powder for cleaning during use, the cleaning accessory 200" is knocked on the surface to be cleaned. The force on the powder will pass through the fiber holes inside the non-woven fabric and then be released from the powder outlet 211b1" to the surface to be cleaned.

[0146] Among them, in order to facilitate the processing and assembly of the non-woven fabric, the non-woven fabric is configured into a circular ring and adapted to the contour of the storage chamber 211c1". However, in other embodiments, the specific shape of the non-woven fabric may also be other. For example, the non-woven fabric may be in multiple circles, and multiple non-woven fabrics are individually fixed to the bristle implant 211b" and at least partially block the powder outlet 211b1". In addition, the present application does not limit the installation method of the non-woven fabric on the bristle implant 211b". For example, the non-woven fabric can be set as a separate part and directly assembled in the storage chamber 211c1". The user needs to take out the non-woven fabric first when replenishing the powder. In addition, the bristle implant 211b" may 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 chamber 211c1" can seep out of the fabric under the action of external force, thereby achieving the purpose of controlling the powder output.

[0147] In some embodiments, the cleaning portion 220" may also be a sponge head or a silicone head, etc., so as to remove the garbage attached to the surface to be cleaned or evenly apply the cleaning powder to the working surface. In addition, the detachable installation between the bristle implant 211b" and the storage member 211c" is achieved by screwing in order to increase the connection area between the bristle implant 211b" and the storage member 211c" to achieve the sealing effect of the storage chamber 211c1". However, in other embodiments, the bristle implant 211b" and the storage member 211c" may also be fixedly installed by other means such as snap-on or bonding, which is not specifically limited here.

[0148] The technical benefits of this solution lie in the coordinated release of efficient cleaning material and cleaning action achieved through the structural design and functional layout of the cleaning accessory. Furthermore, the integration of the base's material storage cavity and the movement of the cleaning unit ensures full utilization of material during each cleaning session, ensuring effective cleaning while enhancing ease of use. This cleaning accessory design effectively meets the requirements of modern cleaning equipment for efficiency and convenience, providing users with superior cleaning services.

[0149] Example 4

[0150] In current portable cleaning device designs, effectively securing and integrating various components to improve the device's structural stability and operating efficiency is a key design challenge. This is especially true when it comes to the connection between the drive source 300 and the cleaning accessory 200, where ensuring structural robustness and functional efficiency is paramount. To this end, the present application proposes a unique first mounting assembly 130 to optimize the interaction between the drive source 300 and the cleaning accessory 200 and enhance overall device performance.

[0151] Please continue reading Figure 3The portable dust removal device 10 also includes 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, and the first mounting assembly 130 is used to cover and fix the driving source 300, and an opening is provided 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.

[0152] Specifically, the first installation assembly 130 has the following features:

[0153] Enveloping and fixing function: The first mounting assembly 130 is designed to envelop and firmly fix the driving source 300. The assembly is designed with appropriate shape and size to ensure that the driving source 300 is not easily displaced during operation, providing good support and stability.

[0154] Connection with the dust chamber 101b: The direct connection between the first mounting assembly 130 and the dust chamber 101b facilitates the collection of garbage in the device, so that the device can quickly transfer the inhaled impurities into the dust chamber 101b during the cleaning process, effectively improving the overall cleaning efficiency.

[0155] Furthermore, an opening is provided on the side of the output shaft 310 of the drive source 300 near the dust chamber 101b in the first mounting assembly 130. This opening allows the cleaning accessory 200 to be easily connected to the output shaft 310 of the drive source 300, creating an efficient power transmission channel. This connection allows the drive source 300 to directly drive the cleaning accessory 200 for effective cleaning, improving transmission efficiency and ensuring the flexibility and responsiveness of the cleaning action.

[0156] Therefore, through the above structure, the first mounting assembly 130 not only contributes to the stability of the device but also increases the efficiency of the coordinated operation between the components. The direct connection between the drive source 300 and the cleaning accessory 200 avoids the power loss that may be caused by indirect transmission, thereby improving the cleaning ability and response speed of the device. This design reduces the complexity of the overall device, making it more convenient for subsequent maintenance and disassembly, and further enhancing the user experience.

[0157] Further, see Figure 13 The first mounting assembly 130 specifically includes: a first fixing portion 131, a second fixing portion 132 and a connecting portion 133, wherein the first fixing portion 131 covers the driving source 300, the second fixing portion 132 is fixedly arranged in the cavity 101, and the two ends of the connecting portion 133 are respectively fixedly connected to the first fixing portion 131 and the second fixing portion 132, and the first fixing portion 132 and the dust chamber 101b are coaxially arranged.

[0158] In some embodiments, the first fixing portion 131 is a cylindrical ring structure, and the first fixing portion 131 is arranged to cover the driving source 300, the output shaft 310 of the driving source 300 extends out of the first fixing portion 131, and the second fixing portion 132 is fixed to the first shell 110 by snapping, and the connecting portion 133 is a plurality of flat plate structures extending perpendicular to the airflow direction and distributed in a circular array. The two ends of the connecting portion 133 are respectively connected to the first fixing portion 131 and the second fixing portion 132, and the first fixing portion 131 and the dust chamber 101b are coaxially arranged. The connecting portion 133 not only realizes the installation of the first fixing portion 131 on the first shell 110, but also realizes the circulation of airflow.

[0159] Among them, for the above-mentioned driving source 300, it can be a driving motor, and the first fixing portion 131 is specially designed to cover the driving motor to ensure that the driving motor remains stable during the operation of the device and prevent displacement or damage due to vibration or other external factors. The second fixing portion 132 can be fixed to the shell 100 (the first shell 110 or the second shell 120), providing a stable installation foundation for the entire first mounting assembly 130, which helps to improve the stability of the overall structure of the device. The connecting portion 133 serves as a bridge between the first fixing portion 131 and the second fixing portion 132, so that the two parts can be firmly connected together. Therefore, the design of the connecting portion 133 ensures the overall strength of the assembly while providing the necessary channel for gas flow.

[0160] When the drive motor is operating, air flows through the connecting space between the dust chamber 101b and the first fixing portion 131, forming a continuous airflow channel, ensuring the cleaning device's dust collection effect during use. This coaxial structure not only enhances airflow mobility but also minimizes airflow obstruction, ensuring that inhaled impurities are quickly transferred to the dust chamber 101b, thereby improving the device's cleaning efficiency.

[0161] In other embodiments, the second fixing portion 132 may be fixed to the first housing 110 by screwing or plugging, and the second fixing portion 132 may also be fixed to the first housing 110. In addition, in some embodiments, the first fixing portion 131 may only partially include the driving source 300, and the first fixing portion 131 and the dust chamber 101b may be eccentrically arranged.

[0162] The technical benefits of the above solution are: Optimizing the component layout and functional integration of the portable dust removal device through the first mounting assembly. Furthermore, the first mounting assembly effectively encases and secures the drive source, providing a convenient connection path, significantly improving the operating efficiency of the drive source and the responsiveness of the cleaning accessories.

[0163] Example 5

[0164] The filter assembly is a key component in cleaning equipment, effectively capturing and filtering a wide variety of waste and dirt. Traditional filtration systems, typically designed with a single filter layer, struggle to meet diverse cleaning needs and can suffer from low filtration efficiency or clogging when handling a wide range of waste types. Therefore, developing a multi-layered filter assembly that effectively filters diverse waste types is crucial.

[0165] See also Figure 14 The filter assembly 400 includes a first filter element 410, a second filter element 420 and a mounting bracket 430; wherein, the first filter element 410 is connected to the first mounting assembly 130 and is located at one end close to the dust suction port 102; the second filter element 420 is connected to the first mounting assembly 130 and connected to the first filter element 410; the mounting bracket 430 is connected to the first mounting assembly 130 and is located at one end away from the dust suction port 102, and is used to cover the second filter element 420; wherein, the first filter element 410 and the second filter element 420 are used to filter different types of garbage.

[0166] Further, see Figure 15 and Figure 16 The mounting bracket 430 is mounted in the first housing 110, and the first filter element 410, the second filter element 420, and the mounting bracket 430 are fixedly connected. The first filter element 410 is located upstream of the second filter element 420 in the direction of airflow, and the diameter of the particles filtered by the first filter element 410 is larger than the diameter of the particles filtered by the second filter element 420.

[0167] In some embodiments, see Figure 17 The first filter element 410 is a conical annular side panel structure, that is, perpendicular to the direction of airflow, the first filter element 410 has a first end 412 close to the first mounting component 130 and a second end 413 away from the first mounting component 130. In the direction of airflow, the distance from the first end 412 to the dust suction port 102 is smaller than the distance from the second end 413 to the dust suction port 102. The first filter element 410 is sleeved on the first mounting component 130, that is, the first mounting component 130 passes through the first filter element 410.

[0168] In some embodiments, see Figure 18 The first filter element 410 is made of stainless steel, and the axis of its conical annular side coincides with the axis of the first shell 110. The first filter element 410 has a plurality of filter holes 411 arranged in a circular array along the airflow direction. The filter holes 411 are waist-shaped, and perpendicular to the airflow direction, the short axis of the waist-shaped filter hole 411 and the thickness direction of the ring are set at a certain angle, thereby ensuring the area of the filter hole 411 while reducing the diameter of the filter particles, thereby obtaining a better filtering effect.

[0169] The design of the first filter element 410 focuses on effectively capturing larger particles of waste, such as debris and dust, and preventing them from entering the finer filter layers, thereby ensuring the cleanliness and service life of subsequent filters. Therefore, the waist-shaped filter holes 411 on the first filter element 410 are a preferred embodiment of this application. In other embodiments, the filter holes 411 on the first filter element 410 can also be circular or have other geometric shapes, which are not specifically limited here.

[0170] The first filter element 410 is made of stainless steel to ensure its strength and corrosion resistance, making it washable and reusable. In other embodiments, the first filter element 410 may be made of other materials, such as metals or plastics. Furthermore, 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 dust suction port 102 is smaller than the distance from the second end 413 to the dust suction port 102. However, in other embodiments, the distance from the first end 412 to the dust suction port 102 is greater than the distance from the second end 413 to the dust suction port 102, meaning that the first filter element 410 in the present embodiment is flipped in the direction of airflow.

[0171] Please continue reading Figure 15 and Figure 16 The second filter element 420 is a ring-shaped cotton cloth structure. The second end 413 is roughly flush with the second filter element 420 on the side facing away from the dust suction port 102 in the airflow direction. The second filter element 420 is used to filter dust particles with a smaller diameter than the first filter element 410.

[0172] In some embodiments, the second filter element 420 is responsible for filtering smaller particulate matter, fine dust, allergens, etc. to improve the cleanliness of air and emissions. Its filtering performance makes the cleaning equipment more efficient when processing different types of garbage. Thus, the filter assembly 400 is configured in a two-layer filtering manner, which essentially increases the effective filtration area, thereby enhancing the filtration effect and reducing the occurrence of reduced suction due to the filter surface being clogged by garbage. The first filter element 410 and the second filter element 420 filter particles with different diameters, facilitating the dumping of garbage and the cleaning of the dust chamber 101b. This multi-layer filtering structure can sequentially capture garbage of different sizes and types, reducing filter blockage, improving overall filtration efficiency, and reducing maintenance frequency.

[0173] In some embodiments, the second filter element 420 is made of cotton cloth. When a small amount of liquid is sucked into the suction port 102, the cotton cloth can absorb the small amount of liquid due to its properties, thereby preventing the liquid from being sucked into the dust removal device 10 and damaging the internal structure. The use of cotton cloth as the material for the second filter element 420 is a preferred embodiment of the present invention. In other embodiments, the second filter element 420 can also be made of high-efficiency filter paper or other porous materials.

[0174] In some embodiments, the first filter element 410 and the second filter element 420 are respectively arranged around the first mounting assembly 130 to separate the cavity 101 into the mounting cavity 101a and the dust cavity 101b, wherein the first filter element 410 adopts a conical annular side structure design, which can increase the effective area of the first filter element 410 and the second filter element 420, that is, increase the effective area of the filter hole 411. Because the shell 100 is slender and close to the size of a pen, the cross-sectional space of the cavity 101 is small, so the inclined surface can be used to easily The filtration area is effectively increased. Furthermore, if the second filter element 420 is a flat filter element, the inclined arrangement of the first filter element 410 can ensure the filtering effect of the second filter element 420 while optimizing space. If both the first filter element 410 and the second filter element 420 are arranged in a flat manner, if the distance between them is small, the filtering surface of the second filter element 420 may not fully contact the airflow to be filtered. Instead, the filtering effect can only be achieved where the projections of the filter holes 411 of the second filter element 420 and the first filter element 410 overlap, thereby weakening the filtering effect. Furthermore, by arranging the first filter element 410 in an inclined manner, space utilization is more rational, making installation between components more simple.

[0175] In some embodiments, to optimize the space within the dust chamber 101b and reduce airflow resistance, the angle between the first filter element 410 and the axis of the first housing 110 may be 46°. In other embodiments, the angle between the first filter element 410 and the axis of the first housing 110 may be 30°, 50°, 68°, or other angles, with a preferred angle range of 25° to 75°. Furthermore, in some embodiments, the first filter element 410 may have an irregular spherical structure to increase the surface area, which is not specifically limited in this application.

[0176] Please continue reading Figure 16, for the above-mentioned mounting bracket 430, the mounting bracket 430 includes a first mounting portion 431, a second mounting portion 432 and a mounting plate 433. The first mounting portion 431 is a circular cylindrical structure, and the first mounting portion 431 is sleeved on the first mounting assembly 130. The second mounting portion 432 is an annular cylindrical structure. The mounting plate 433 is a flat plate structure perpendicular to the airflow direction. In the direction perpendicular to the airflow, the two ends of the mounting plate 433 are respectively connected to the first mounting portion 431 and the second mounting portion 432, and the mounting plate 433 is arranged on the side of the mounting bracket 430 away from the dust suction port 102. The first mounting portion 431 and the second mounting portion 432 together enclose an annular mounting cavity 101a, and the second filter element 420 is accommodated in the mounting cavity 101a. The first filter element 410 is fixed to a side of the mounting bracket 430 close to the dust suction port 102, and perpendicular to the direction of airflow, the diameters of the first filter element 410 and the mounting bracket 430 are the same and larger than the diameter of the dust chamber 101b, thereby further rationally utilizing the effective filtering area of the first filter element 410 to enhance the filtering effect.

[0177] The present application does not impose any specific restrictions on the specific structure of the mounting bracket 430, as long as it can achieve the installation of the first filter element 410 and the second filter element 420 on the first housing 110. The provision of the mounting plate 433 not only enables the connection between the first mounting portion 431 and the second mounting portion 432, but also allows the mounting plate 433 to abut the second filter element 420 in the direction of airflow, thereby limiting and fixing the second filter element 420 in the direction of airflow. Furthermore, the circumferential arrangement of the mounting plates 433 allows the filtered gas to flow out of the axial direction of the first housing 110 while achieving the aforementioned functions.

[0178] like Figure 14 and Figure 16 As shown, an annular groove 432a is provided on the outer side of the second mounting portion 432, and the portable dust removal device 10 also includes a sealing ring 600, and the annular groove 432a is used to accommodate the sealing ring 600, and a sealing ring 600 is also provided between the first mounting component 130 and the mounting frame 430, thereby realizing the air duct sealing of the middle and peripheral sides of the ring of the filter module 400, thereby avoiding the accumulation of dust between the gaps and the loss of wind force.

[0179] Continue as Figure 16 As shown, the first filter element 410 also includes a reinforcement ring 414, which is arranged on the side of the first end 412 away from the dust suction port 102 and extends along the direction of the airflow. The setting of the reinforcement ring 414 can increase the strength of the first filter element 410, reduce the deformation of the first filter element 410 caused by the impact of airflow and garbage, thereby increasing the service life of the first filter element 410.

[0180] Continue as Figure 16As shown, a handle portion 432b is provided on the side of the second mounting portion 432 facing away from the 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 remove the filter assembly 400 from the first housing 110 when the first housing 110 and the second housing 120 are disassembled, thereby improving the user experience. Specifically, to increase the volume of the handle portion 432b and facilitate the user's grip, the handle portion 432b is provided on the second mounting portion 432. However, in other embodiments, the handle portion 432b may also be provided on the first mounting portion 431, which is not specifically limited here.

[0181] The technical benefit of this solution is that, through the rational structural design of the first and second filter elements and the mounting bracket of the filter assembly, it effectively filters a variety of waste types. This innovative design not only improves the filtration efficiency and service life of the cleaning equipment, but also optimizes the cleaning effect, making it suitable for a variety of cleaning scenarios.

[0182] Example 6

[0183] As the functionality of portable cleaning equipment continues to improve, the performance of the wind pressure component, as an important component of cleaning equipment, directly affects the cleaning efficiency of the equipment. Achieving strong wind pressure and efficient air flow while maintaining a compact device has become a major design challenge. This application provides a highly efficient portable dust removal device by designing a wind pressure component, optimizing airflow management and improving cleaning results.

[0184] See also Figure 3 and Figure 19 The above-mentioned wind pressure assembly 500 specifically includes a wind pressure motor 510 and a centrifugal fan blade 520, which are arranged in the installation 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, thereby causing gas flow in the cavity 101.

[0185] Among them, by designing the structure of the wind pressure assembly 500, the wind pressure assembly 500 is arranged in the installation cavity 101a, specifically located inside the second shell 120. This layout not only effectively utilizes the internal space, but also reduces the overall weight of the device, improving portability. In addition, by designing the configuration of the wind pressure motor 510 and the centrifugal fan blades 520, a high-efficiency wind pressure motor 510 is used for electric drive, providing sufficient power for the entire cleaning device, ensuring stable operation under high load conditions. In addition, the centrifugal fan blades 520 are mounted on the output shaft 511 of the wind pressure motor 510. This design allows the wind pressure motor 510 to directly drive the fan blades to achieve high-speed rotation, thereby forming a high-intensity wind pressure within the cavity 101.

[0186] Further, see Figure 20 The centrifugal fan 520 also includes a chassis 521 and a blade module 522, wherein the blade module 522 is fixed on the chassis 521 and is located on the side of the chassis 521 facing the dust suction port 102. The chassis 521 has a conical side wall and an assembly hole 521a is provided in the center.

[0187] In some embodiments, for the above-mentioned chassis 521, the angle between the side wall of the cone and the axis can be 63°, and the chassis 521 is mounted on the power shaft 511 of the wind pressure motor 510 through the assembly hole 521a, wherein the chassis 521 has a circular projection on the axis, which can ensure that the centrifugal fan blades 520 rotate in the installation cavity 101a while obtaining a larger area, thereby increasing the installation area of the blade module 522, and the chassis 521 is set with a conical side wall, which can increase the actual surface area on the same projection area, thereby increasing the installation area of the blade module 522, and then increasing the contact area between the centrifugal fan blades 520 and the airflow, thereby increasing the airflow guidance effect.

[0188] In other embodiments, the projection of the chassis 521 on the axis can be elliptical or polygonal. If the space in the mounting cavity 101a is sufficient, the chassis 521 can also be a flat plate-like structure with no tilt or protrusion on the axis. Alternatively, if weight is not a consideration, the chassis 521 can be directly configured as a solid conical or spherical structure. Furthermore, the chassis 521 can also be configured as a spherical or other protruding structure to increase the projected area of the chassis 521 on the axis. When the chassis 521 has conical sidewalls, the angle between the conical sidewall and the axis can be 15°, 23°, 35°, 45°, or 75°, etc., without specific limitations herein.

[0189] Among them, the conical side wall structure design of the above-mentioned chassis 521 not only makes its shape beautiful, but also has important functional advantages. Through optimized design, the actual surface area of the chassis 521 is effectively increased compared to the projected area formed by it. Such a shape can maximize the installation area of the blades, creating conditions for the arrangement of more blades, so that the blades can be arranged more densely, significantly increasing the contact area between the centrifugal fan blades 520 and the airflow. Under the same space constraints, by increasing friction and pushing effects, the intensity of wind pressure can be increased, effectively meeting the high demands of the portable dust removal device 10 during the cleaning process.

[0190] Further, see Figure 21The above-mentioned blade module 522 includes blades 522a, which are arc-shaped and distributed in a circular array on the chassis 521. The arc-shaped blades 522a can be designed to be longer on the same chassis 521 size, thereby increasing the contact area between the blades 522a and the wind. In the flow direction of the airflow, the blade 522a has a first side 522a1 located upstream, and a second side 522a2 located downstream. 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 airway between the blades 522a, and the height of the airflow flowing from the first side 522a1 to the second side 522a2 will gradually decrease, and the binding ability of the blade 522a on the airflow will gradually decrease, releasing part of the energy of the airflow, reducing the collision kinetic energy of the airflow flowing out of the fan blade and the second shell 120, reducing the loss of airflow energy, and improving the air outlet efficiency.

[0191] Among them, the axes mentioned for describing the orientation, unless otherwise specified, refer to the central axis of the cone with the conical side wall of the chassis 521, and in the embodiment of the present application, the chassis 521 and the second shell 120 are coaxially arranged, that is, in the embodiment of the present application, the axis of the chassis 521 is also the axis of the second shell 120.

[0192] For further information, please refer to Figure 21 In order to further reduce the loss of wind power, the blade 522a is composed of a first blade 522b and a second blade 522c; wherein the first blade 522b and the second blade 522c are arranged in sequence at intervals, and in the direction perpendicular to the axis, the projection length of the first blade 522b on the chassis is greater than that of the second blade 522c, and the distance from the first side 522a1 of the first blade 522b to the axis is less than that of the second blade 522c.

[0193] Among them, the grouping design of blades 522a can ensure the space between blades 522a and the airflow inlet when the cross-sectional size of blades 522a is small, and also increase the guide area of blades 522a. In addition, the grouping design of blades 522a can also perform secondary diversion of the airflow, so that the airflow is more evenly dispersed when passing through the centrifugal fan blades 520, and the wind loss is further reduced.

[0194] In some embodiments, as Figure 21As shown, the number of first blades 522b and second blades 522c is five, and the five first blades 522b and the five second blades 522c are arranged in a circular array around the axis, and the first blades 522b and the second blades 522c are spaced apart in sequence. In a direction perpendicular to the axis, the projected length of the first blade 522b on the chassis 521 is greater than the projected length of the second blade 522c on the chassis 521, and the end surfaces of the second side 522a2 of the first blade 522b and the second side 522a2 of the second blade 522c are both arc-shaped and form the same circular arc. The distance from the first side 522a1 of the first blade 522b to the axis is less than the distance from the first side 522a1 of the second blade 522c to the axis, and in a direction perpendicular to the axis, the distances from the first blade 522b and the second blade 522c to the chassis 521 on the same diameter of the chassis 521 are the same.

[0195] In some embodiments, the number and size of the first blades 522b and the second blades 522c are designed to optimize the spatial layout and wind power loss according to the size of the dust removal device 10. However, in other embodiments, the number of the first blades and the second blades can also be 3, 6, or 9. In addition, to simplify the structure and facilitate processing, the blades 522a are composed of the first blade 522b and the second blade 522c. In other embodiments, the blades 522a can also include a third blade 522a or a fourth blade 522a, etc., which are not specifically limited here.

[0196] The layered and spaced arrangement of the first blades 522b and second blades 522c allows for a more evenly dispersed flow as the air passes through the centrifugal blades 522, avoiding wind loss caused by airflow converging at a specific location. This even distribution of airflow allows each area to fully participate in the propulsion process, further increasing overall wind pressure. Furthermore, the distance from the first side 522a1 of the first blade 522b to the axis is designed to be shorter than that from the second blade 522c. This allows the first blade 522b to more effectively guide airflow into the second blade 522c under the action of centrifugal force, thereby achieving secondary flow diversion.

[0197] By performing a secondary diversion of the airflow, the airflow is more evenly distributed, effectively reducing wind loss and improving the overall performance of the device. For example, when the airflow flows evenly, its kinetic energy is more fully utilized, avoiding unnecessary energy loss in areas of insufficient pressure. Furthermore, after passing through the carefully designed blade module 520, the airflow can be more effectively converged and propelled, thereby causing more dust and impurities to be drawn into the device, improving the cleaning effect.

[0198] See also Figure 19 and Figure 22In order to converge and guide the airflow to the first side 522a1 of the centrifugal fan blade 520, the wind pressure assembly 500 also includes an air guide 540, wherein the air guide 540 is installed on the second shell 120 and the position installation cavity 101a, and the air guide 540 is located upstream of the centrifugal fan blade 520 in the flow direction of the gas. The air guide 540 is used to converge and guide the airflow in a direction perpendicular to the direction of the airflow, and the centrifugal fan blade 520 then guides the airflow converged by the air guide 540 toward the periphery.

[0199] like Figure 22 As shown, the air guide 540 is annular in shape as a whole, and a conical first groove 541 and a second groove 542 are provided on both sides of the middle portion in the axial direction. The first groove 541 and the second groove 542 are connected, and the overall wall thickness of the air guide 540 remains consistent. The air guide 540 is in the shape of a vortex formed by rotating the axis near the sharp corner. The outer side of the air guide 540 is provided with reinforcing ribs to increase the strength of the air guide 540 and prevent the air guide 540 from deforming under the action of wind pressure, thereby affecting the convergence effect of the air guide 540. Among them, in the flow direction of the gas, the first groove 541 is located upstream of the second groove 542. The first groove 541 is used to concentrate the airflow in a direction perpendicular to the axis, thereby directing the airflow to the first side 522a1 of the centrifugal fan blade 520, avoiding wind loss caused by the dispersion of the airflow. The second groove 542 is used to be close to the blade 522a to form an air passage between the centrifugal fan blade 520, thereby guiding the air flow before entering the blade 522a, further facilitating the air flow and reducing wind loss.

[0200] In other embodiments, the first groove 541 and the second groove 542 may also be spherical or in other shapes, or the air guide 540 may also be provided in a split body, that is, the air guide 540 is two elements, and the first groove 541 and the second groove 542 are provided on two parts respectively. In some embodiments, without considering the weight of the air guide 540, the air guide 540 may also be a solid gyroid structure, which is not specifically limited here.

[0201] Please continue reading Figure 19 In order to facilitate the installation between the centrifugal fan blade 520 and the wind pressure motor 510, an installation angle 521a1 is provided on the side of the assembly hole 521a close to the wind pressure motor 510, so that the centrifugal fan blade 520 can be better mounted on the power shaft 511 of the wind pressure motor 510, thereby facilitating production, reducing assembly time during production, and thus reducing production costs.

[0202] In some embodiments, the chassis 521 is provided with reinforcing ribs on the side of the axis away from the centrifugal fan blades 520, thereby increasing the strength of the centrifugal fan blades 520 and preventing the centrifugal fan blades 520 from being deformed due to the action of wind pressure, thereby affecting the guide effect of the centrifugal fan blades 520 and damaging the fan blades.

[0203] Among them, in order to reduce the weight of the centrifugal fan blade 520, in the axial direction, part of the blade module 522 is extended out of the chassis 521, and the blade module 522 is arranged in an outwardly inclined manner. It can reduce the projection area of the chassis 521 while ensuring the same diversion area, that is, reduce the volume of the chassis 521, thereby reducing the weight of the centrifugal fan blade 520 and the weight of the dust removal equipment 10, so as to facilitate user mobility and improve user experience.

[0204] The technical benefit of this solution lies in the modular design of the wind pressure assembly, which not only simplifies the assembly process but also improves assembly efficiency and reduces production costs. Furthermore, as the centrifugal impellers rotate at high speed, the air inside the cavity is rapidly drawn in and pressurized, creating a strong wind pressure within the cavity. This wind pressure effectively draws debris from the surface being cleaned into the cavity, improving cleaning efficiency. This design effectively enhances the overall performance of the device, ensuring a rapid and thorough cleaning process.

[0205] Example 7

[0206] Modern portable dust removal equipment places higher demands on the structural design of its components, particularly regarding the installation and connection of the wind pressure motor. Traditional designs often lack flexibility, leading to unstable operation and insufficient wind pressure. The second mounting assembly proposed in this application features a modular structure. By effectively enclosing and securing the wind pressure motor, it not only improves the overall performance of the device but also ensures functional integration within a limited space.

[0207] In one embodiment, continue as Figure 3 As shown, the portable dust removal device 10 also includes a second mounting assembly 530; wherein, the second mounting assembly 530 is arranged in the second shell 120 and fixed in the mounting cavity 101a, and the second mounting assembly 530 is used to cover and fix the wind pressure motor 510, and an opening is provided on 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.

[0208] The securing and enveloping design of the second mounting assembly 530 ensures that the wind pressure motor 510 remains stable during operation, reducing operational instability caused by vibration and improving the overall operational safety and reliability of the dust removal device 10. Furthermore, the opening design of the second mounting assembly 530 allows the centrifugal fan blades 520 to connect directly and quickly to the wind pressure motor 510, ensuring efficient wind pressure generation. This structure reduces airflow resistance, improves the wind pressure efficiency of the device, and thus enhances dust collection effectiveness.

[0209] Further, see Figure 23 and Figure 24 The second mounting assembly 530 specifically includes: a mounting base 531, a mounting cover 532, a connecting element 533 and a mounting cylinder 534, wherein the mounting cover 532 and the mounting base 531 jointly enclose and mount the wind pressure motor 510, the connecting element 533 is bent in the axial direction of the second shell 120, and the mounting cover 532 is provided with a heat dissipation hole 532b, and the heat dissipation hole 532b is generally in a right-angled fan shape.

[0210] Specifically, see Figure 25 The mounting seat 531 is a cylindrical cavity wall structure without a top cover, and the mounting cover 532 is a cylindrical cavity wall structure without a bottom wall. The mounting seat 531 and the mounting cover 532 are both coaxially arranged with the second shell 120. The mounting cover 532 is plugged into the mounting seat 531. The mounting cover 532 and the mounting seat 531 jointly enclose and install the wind pressure motor 510. A through hole 532a is provided in the middle of the mounting cover 532. The power shaft 511 of the wind pressure motor 510 is plugged into the through hole 532a to extend out of the mounting cover 532 and be installed with the centrifugal fan blade 520.

[0211] The wind pressure motor 510 is mounted by the mounting cover 532 and the mounting base 531, ensuring that the motor is stable and fully protected. This structural design effectively prevents damage to the motor from the external environment while providing good support.

[0212] In some embodiments, the connecting element 533 is a rib plate structure, the mounting cylinder 534 is a circular cylindrical shell structure, and the connecting element 533 is connected to the inner wall of the mounting cylinder 534 at one end and the mounting seat 531 at the other end in a direction perpendicular to the axis of the second shell 120 to realize the installation of the wind pressure motor 510 on the second shell 120.

[0213] Furthermore, the connecting element 533 is bent in the axial direction of the second shell 120, that is, the connecting element 533 is in an arc shape, and the number of the connecting elements 533 is 5, and the 5 connecting elements 533 are arranged around the mounting seat 531. The arc shape of the connecting element 533 can increase the contact area while guiding the gas to reduce the resistance to the airflow.

[0214] The curved structure of connecting element 533 helps guide the gas flow along a smoother path, reducing airflow resistance. This optimized design ensures more efficient gas flow after passing through wind pressure motor 510, reduces the risk of airflow convergence and vortex generation, and improves wind pressure utilization.

[0215] Among them, in order to fit the shape of the wind pressure motor 510 and the installation cavity 101a, the outer contours of the mounting seat 531, the mounting cover 532 and the mounting cylinder 534 are set 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 to avoid uneven wind pressure and thus cause resistance. In other embodiments, the wind pressure motor 510 can also be fixedly installed on the second shell 120 with other structures to achieve fixed installation of the wind pressure motor 510.

[0216] In some embodiments, the connecting element 533 can be a flat structure or a block structure with a larger cross-sectional area, and its two ends are respectively connected to the second shell 120 and the mounting base 531 to fix the mounting base 531 on the second shell 120. In other embodiments, the number of connecting elements 533 can also be 2, 3 or 6, etc., and multiple connecting elements 533 are arranged around the mounting base 531, or while ensuring the installation strength of the mounting base 531, the number of connecting elements 533 is directly set to one.

[0217] Among them, in order to simplify the structure of the second shell 120 and reduce the production difficulty of the second shell 120, the installation unit 530 can be an independent component, and the wind pressure motor 510 is installed on the installation unit 530 and then installed together on the second shell 120. However, in some other embodiments, the installation unit 530 can also be integrally formed with the second shell 120, which is not specifically limited here.

[0218] In some embodiments, continuing as Figure 24 As shown, the mounting cover 532 is provided with four heat dissipation holes 532b. The heat dissipation holes 532b are generally in the shape of a right-angled fan. The four heat dissipation holes 532b are evenly distributed on the mounting cover 532, so that the mounting cover 532 has an overall hollow structure. The provision of the heat dissipation holes 532b facilitates heat dissipation of the wind pressure motor 510, and can reduce the power loss or damage caused by overheating of the wind pressure motor 510 due to continuous operation, thereby increasing the life of the dust removal device 10. In other embodiments, the heat dissipation holes 532b can also be different shapes such as elliptical, circular, or polygonal, or the mounting cover 532 can be directly configured as a porous grid structure. The number and shape of the heat dissipation holes 532b are not specifically limited here.

[0219] The mounting cover 532 is provided with heat dissipation holes 532b, which are generally in the shape of a right-angled fan, to facilitate the smooth dissipation of heat generated by the wind pressure motor 510 during operation. This heat dissipation design can effectively prevent the motor from overheating, thereby improving the motor's operating efficiency and service life.

[0220] The technical benefits of this embodiment are as follows: the modular wind pressure assembly simplifies the structure and improves assembly efficiency by tightly integrating the wind pressure motor and centrifugal blades. Furthermore, the strong wind pressure generated ensures a more stable wind flow, ensuring maximum cleaning effectiveness. During use, the powerful wind pressure allows users to quickly clean various surfaces, thereby increasing user satisfaction.

[0221] Example 8

[0222] In portable dust removal equipment, the cavity design and sealing performance directly impact the cleaning efficiency and user experience. Traditional portable dust removal devices often lack effective sealing mechanisms, resulting in uneven air pressure or dust leakage during operation, which in turn affects the dust removal effect and the effectiveness of the device. Therefore, developing a more reasonable cavity sealing structure can improve air pressure control and significantly enhance the performance of portable dust removal equipment, which is of great practical significance.

[0223] See also Figure 26 、 Figure 27 and Figure 28 The first shell 110 also includes a mounting column 111 and a connecting rib 112, which respectively connects the mounting column 111 and the inner wall of the first shell 110; and the portable dust removal device 10 also includes a dust shield 700, which is annular and is sleeved on the mounting column 111, wherein the dust shield 700 is used to close or open the cavity 101 under the action of wind pressure.

[0224] Among them, the mounting column 111 is a cylindrical ring structure, and the number of connecting ribs 112 is multiple (such as 3), and the multiple connecting ribs 112 are arranged in a circular array around the axis of the first shell 110. The connecting ribs 112 respectively connect the mounting column 111 and the inner wall of the first shell 110, and the output shaft 310 of the driving source 300 and the cleaning accessory 200 pass through the mounting column 111.

[0225] Among them, the dust shield 700 is annular and made of sponge. The dust shield 700 includes a mounting end 710, a rotating end 720 and a rotating shaft 730. Among them, 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 degree of shielding of the cavity 101 to close or open the cavity.

[0226] In other embodiments, the dust shield 700 is merely an annular sheet that is easily deformed and is sleeved in the mounting column 111, so that the dust shield 700 bends to a corresponding degree when wind pressure is generated in the cavity 101 to change the degree of shielding of the cavity 101, thereby opening the cavity to a certain extent so that air carrying impurities is sucked into the cavity 101; and, when the wind pressure in the cavity 101 stops, the dust shield 700 returns to its original sheet shape to change the degree of shielding of the cavity 101, thereby closing the cavity to a certain extent so that impurities in the cavity 101 will not be poured out.

[0227] In other embodiments, the present application may not provide the mounting column 111 and the connecting rib 112 in the first shell 110, and the dust shield 700 may be merely an annular sheet that is easily deformed. The dust shield 700 is sleeved on the output shaft 310 of the motor of the driving source 300, so that the dust shield 700 bends to a corresponding degree when wind pressure is generated in the cavity 101, thereby changing the degree of shielding of the cavity 101, thereby opening the cavity to a certain extent, so that air carrying impurities is sucked into the cavity 101; and, when the wind pressure in the cavity 101 stops, the dust shield 700 returns to its original sheet shape, thereby changing the degree of shielding of the cavity 101, thereby closing the cavity to a certain extent, so that impurities in the cavity 101 will not be poured out.

[0228] See also Figure 29 The two ends of the rotating shaft portion 730 are respectively connected to the mounting end 710 and the rotating end 720. The thickness of the rotating shaft portion 730 is less than the thickness 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 beneficial to the rotation of the rotating end 720 of the dust shield 700, and prevents the rotating end 720 from rotating too little when the wind force is small, thereby affecting the suction of garbage and causing loss of wind force.

[0229] Among them, the annular design of the dust shield 700 enables it to adapt to the shape of the cavity 101, and effectively open or close the opening part of the cavity 101 under the action of wind pressure, preventing dust and garbage from escaping during the vacuuming process, and ensuring the complete inhalation of dust and particulate matter.

[0230] In other embodiments, the dust shield 700 can be made of a soft, easily deformable material such as polyvinyl chloride or thermoplastic polyurethane elastomer. Furthermore, the three connecting ribs 112 shown in the figure are intended to strengthen the mounting strength of the mounting post 111 on the first housing 110. In other embodiments, the connecting ribs 112 can be two, five, or seven, or multiple connecting ribs 112 can be arranged in a circular array around the axis of the first housing 110. Alternatively, the number of connecting ribs 112 can be limited to one while ensuring the mounting strength of the mounting post 111. This is not specifically limited here.

[0231] In some embodiments, the connecting ribs 112 are arranged in a circular array along a direction perpendicular to the airflow (i.e., the axial direction of the first shell 110), and the connecting ribs 112 are close to the dust suction port 102 in the direction of the airflow. From the connection between the connecting ribs 112 and the first shell 110 to the connection between the connecting ribs 112 and the mounting column 111, the thickness of the connecting ribs 112 gradually decreases, and its contour is a smooth transition, that is, the connecting ribs 112 are concave at the dust suction port 102, which can reduce the volume of the connecting ribs 112 while ensuring the installation strength of the mounting column 111 and the first shell 110, and the smooth transition of the connecting ribs 112 on the side close to the dust suction port 102 can reduce the resistance when the garbage is sucked into the dust chamber 101b, that is, increase the suction strength.

[0232] Among them, a mounting protrusion 111a is provided at one end of the mounting column 111 facing away from the dust suction port 102 in the direction of airflow. When installed, the dust shield 700 uses its own elasticity to short-term expand the outline from the mounting protrusion 111a to the mounting column 111, and the inner diameter of the mounting end 710 is the same as the outer diameter of the mounting column 111. The mounting end 710 is adapted to be installed on the mounting column 111. In the direction of airflow, one side of the dust shield 700 abuts against the connecting rib 112, and the other side abuts against the mounting protrusion 111a, thereby realizing the fixed installation of the dust shield 700, and it will not swing or move due to the action of wind pressure. The embodiment of the present application achieves fixed installation on the dust removal equipment 10 through a sleeve-type method. Compared with the traditional bonding or clamping installation method, the structural design is simpler, the number of parts and assembly steps are relatively small, and compared with bonding or clamping, which are easy to fall off or loosen under the action of wind pressure, the installation method of the embodiment of the present application is more secure, thereby extending the service life of the dust shield 700 and providing a better user experience.

[0233] Furthermore, the mounting protrusion 111a has a chamfer on the side facing away from the dust suction port 102 in the direction of airflow. The chamfer can facilitate the installation of the dust shield 700 during the production process. During installation, the dust shield 700 can use the chamfered profile to gradually increase the inner hole profile of the mounting end 710, thereby sliding out of the mounting protrusion 111a to achieve installation. Furthermore, the number of mounting protrusions 111a can be three, and the three mounting protrusions 111a are distributed in a circular array perpendicular to the direction of airflow. The mounting protrusions 111a are arranged in this spaced manner to further facilitate the installation of the dust shield 700. When the mounting end 710 is difficult to insert into the mounting protrusion 111a whose size is larger than its own inner hole diameter, the mounting end 710 can be installed by inserting the mounting protrusions 111a one by one, thereby reducing the degree of deformation of the mounting end 710 during installation, thereby reducing the difficulty of installation of the mounting end 710, and further ensuring the installation strength of the dust shield 700 on the first shell 110.

[0234] In some embodiments, the rotating end 720 is angled at 75° to the airflow direction, and the side of the rotating end 720 facing away from the suction port 102 is tilted inwardly toward the axis of the first housing 110 in the airflow direction. Because the housing in this embodiment is an elongated structure and the cross-section of the dust chamber 101b is small, the angled arrangement of the rotating end 720 to the airflow can increase the radial length of the rotating end 720, thereby amplifying the shielding effect during rotation. The larger area of the rotating end 720 is more conducive to receiving wind force, making the rotating end 720 easier to rotate. Among them, the 75° angle between the rotating end 720 and the airflow direction is a preferred solution. In other embodiments, the rotating end 720 can also be at different angles such as 45°, 30°, or 90°.

[0235] In some embodiments, the contour of one side of the first shell 110 near the dust suction port 102 gradually decreases, and the overall thickness of the first shell 110 remains uniform, that is, the contour of the dust chamber 101b near the dust suction port 102 gradually decreases, so that the first shell 110 has a smaller dust suction range near the dust suction port 102, which is convenient for user operation. In addition, the rotating end 720 and the airflow direction are tilted. Because the contour of the dust chamber 101b near the dust suction port 102 is reduced, when the dust removal device 10 is inverted or tilted, the garbage will reversely push the dust barrier 700 against the inner wall of the first shell 110, thereby forming a self-locking function, further preventing garbage from leaking from the dust suction port 102, and improving the user experience.

[0236] The technical effect of the above solution is that through the ingenious combination of the mounting post, connecting ribs, and dust shield of the first shell, the cavity is effectively sealed and the wind pressure is properly controlled. The dust shield's sealing design effectively prevents dust leakage, ensuring that dust does not flow back out during vacuuming, and fully utilizing wind pressure to achieve optimal dust removal. Furthermore, through the dynamic adjustment of the dust shield, the portable dust removal device can automatically adjust the cavity's sealing state according to actual work needs, thereby maintaining good wind pressure and enhancing suction.

[0237] Embodiment 9

[0238] When using a portable dust removal device 10, especially in low-light or confined spaces, it's often difficult for users to accurately identify the area to be cleaned. This can result in suboptimal cleaning results or the omission of difficult-to-detect dirt and dust. Therefore, developing a portable dust removal device 10 that can provide illumination is of great practical significance. By integrating a lighting component into the device, cleaning efficiency can be effectively improved, ensuring that the cleaning area is fully illuminated.

[0239] Please continue reading Figure 3 The portable dust removal device 10 also includes a lighting assembly 800, which is installed on the first mounting assembly 130 and is arranged around the output shaft 310 of the driving source 300. When the lighting assembly 800 is working, the emitted light is emitted from the dust suction port 102 to illuminate the area to be cleaned.

[0240] In some embodiments, when the portable dust removal device 10 is turned on, the light assembly 800 will work synchronously to ensure continuous lighting while the user is cleaning. This function not only makes the device more practical, but also effectively reduces cleaning omissions caused by insufficient light.

[0241] See also Figure 30 In order to allow users to effectively use light to illuminate dust in dark conditions, the lighting assembly 800 specifically includes a circuit board 810 and a light-emitting element 820. The circuit board 810 is annular and is mounted on the first mounting assembly 130 and is arranged around the output shaft 310 of the motor of the driving source 300. The light-emitting element 820 is an LED lamp bead. There are six light-emitting elements 820, which are welded to the circuit board 810 in a circular array. The light of the light-emitting element 820 is arranged toward the dust suction port 102. When the light-emitting element 820 is in working state, the light emitted will be emitted from the dust suction port 102 to illuminate the surface to be cleaned.

[0242] Among them, the light-emitting element 820 uses LED lamp beads in order to reduce the volume and cost of the lighting assembly 800. In other embodiments, the light-emitting element 820 can also use other types of lamps such as incandescent lamps, fluorescent lamps or laser lamps, which are not specifically limited here. In addition, in the embodiment of the present application, 6 light-emitting elements 820 are selected to be arranged in a circular array, which can reduce the size of the light-emitting element 820 in a single direction while obtaining more uniform and brighter light. The dust removal device 10 is cylindrical as a whole. When the user holds the first shell 110 in use, it can be rotated 360° and there is no difference in the angle of use. Therefore, the multiple light-emitting elements 820 are arranged in a circular array to emit light evenly, so that the user can maintain the same lighting effect when holding it at different angles.

[0243] In other embodiments, only one light-emitting element 820 may be used, or two, four, seven, or other light-emitting elements may be used, provided that the required intensity is met. The light-emitting elements 820 may be arranged in a circular array or in an irregular pattern on the circuit board 810, without any specific limitation herein. For example, if the first housing 110 is provided with a gripping and positioning structure or the first housing 110 is elliptical in shape, and the user grips the first housing 110 at a specific angle when using the dust removal device 10, the light-emitting elements 820 may be arranged in a clustered manner and project light out of the suction port 102 at a fixed angle.

[0244] In some embodiments, in order to simplify the structure of the lighting assembly 800 and reduce the cost of the dust removal equipment 10 while allowing for a more secure installation, the light-emitting component 820 is directly welded to the circuit board 810 by welding. In other embodiments, the light-emitting component 820 can also be fixed to the first mounting assembly 130 by setting a snap-fit structure, and the electrical connection between the light-emitting component 820 and the circuit board 810 can be achieved through wires. Alternatively, in some embodiments, the light-emitting component 820 can be fixed to the circuit board 810 by plugging and achieve electrical connection with the circuit board 810.

[0245] Further, see Figure 31 The lighting assembly 800 also includes a baffle 830, which is a circular transparent plate-shaped structure. The baffle 830 is made of transparent polycarbonate. The baffle 830 is arranged on the first fixing portion 131 to seal the light-emitting component 820 and the circuit board 810, thereby preventing the dust removal device 10 from being adhered to dust during operation, thereby shielding the light-emitting component 820, and further affecting the light intensity of the light-emitting component 820. The adhesion of dust can easily affect the electrical connection between the light-emitting component 820 and the circuit board 810. The baffle 830 is made of a transparent material, and the light-emitting component 820 can directly pass through the baffle 830 without causing loss of light intensity.

[0246] In some embodiments, 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 arc. Figure 13 As shown, a positioning groove 131a is provided on the first fixing portion 131, the baffle 830 is accommodated in the first fixing portion 131 and the positioning blocks 831 are respectively accommodated in the positioning grooves 131a, and the side of the baffle 830 facing away from the suction port 102 is the installation surface, and the installation surface is affixed with adhesive, and the baffle 830 is adhered to the bottom surface of the positioning groove 131a through the positioning block 831, thereby realizing the installation of the baffle 830 on the first fixing portion 131.

[0247] In some embodiments, the specific material and shape of the baffle 830 can also be a transparent or light-transmitting material such as polyethylene terephthalate, polyvinyl chloride, or tempered glass, which is not specifically limited in this application. The baffle 830 is designed to be circular in order to fit the contour 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 fit the shape of the first fixing portion 131 and be elliptical or polygonal accordingly. In addition, the baffle 830 can be set not to fit the shape of the first fixing portion 131 to partially shield the light-emitting component 820, or through an arc-shaped baffle 830 structure extending in the axial direction of the first shell 110, such as the baffle 830 is in the shape of a ring or a conical sidewall, and 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 component 820.

[0248] For further information, please refer to Figure 1 Hehe Figure 32 The light assembly 800 further includes a light blocking member 840, which is annular in shape and is disposed around the side of the first housing 110 close to the dust suction port 102. The first mounting assembly 130, the connecting portion 133, the base 210, and the first housing 110 are all light-permeable. The dust removal device 10 is provided with a light blocking member 840 on the periphery of the dust suction port 102 to block part of the light emitted by the light-emitting member 820, thereby concentrating the light emitted by the light-emitting member 820 in the dust suction range corresponding to the dust suction port 102 and preventing an excessively large illumination area. The user can intuitively determine the cleaning area of the dust removal device 10. Furthermore, the light blocking member 840 partially blocks the light emitted by the light-emitting member 820, thereby reducing the light intensity entering the user's eyes while 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.

[0249] Specifically, see Figure 26 and Figure 32The first shell 110 is provided with an annular mounting notch 113 on one side close to the dust suction port 102. The light blocking member 840 is accommodated and installed in the mounting notch 113 and is adhesively fixed to the first shell 110. The edges of the light blocking member 840 and the outer contour of the first shell 110 are adapted to fit so that there is no obvious gap in the outer contour. The light blocking member 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. The material is soft and elastic, which makes it easy for users to hold it during use and has a better feel. The hardness and wear resistance are relatively superior, and it has good oil resistance, chemical resistance and corrosion resistance, so that the dust suction port 102 is not easy to wear and corrode during use, thereby improving the service life of the dust removal equipment 10 and improving the user experience.

[0250] Among them, in order to facilitate installation and reduce production costs, the edges of the light blocking member 840 are all round, and the shape of the installation notch 113 is adapted to the outline of the light blocking member 840. However, in other embodiments, the light blocking member 840 can also be a multi-segment or single-segment ring structure. The light blocking member 840 is installed at the dust suction port 102 of the first shell 110 to partially block the light of the light-emitting member 820, so as to reduce the area of the illuminated area and the emitted light. In addition, in some embodiments, the outer surface of the first shell 110 and the light blocking member 840 can be provided with mutually interlocking structures such as protrusions and recesses. On the one hand, the area of the light blocking member 840 on the first shell 110 can be increased to facilitate the user's grip, and on the other hand, the appearance of the dust removal device 10 can be increased. The first shell 110 is arranged in a light-transmitting manner to facilitate the user to observe the storage capacity of the dust chamber 101b.

[0251] Among them, in order to reduce the installation steps, save production time, and ensure the installation strength of the light blocking member 840, the light blocking member 840 and the first shell 110 can be integrally injection molded by two-color injection molding, so that the light blocking member 840 and the first shell 110 are integrally molded, but in other embodiments, the light blocking member 840 can be set separately from the first shell 110, and the light blocking member 840 can be fixed to the first shell 110 by sleeve installation and bonding, or in some embodiments, the light blocking member 840 can also be fixed to the first shell 110 by snapping or screwing, which is not specifically limited here.

[0252] The technical effect of the above solution is that by integrating the lighting assembly with the first mounting assembly, light can be emitted from the suction port to illuminate the area to be cleaned. This design greatly improves the practicality of the cleaning device, allowing the user to clearly observe the area to be cleaned during cleaning, making it easier to detect hidden dirt and dust, thereby improving cleaning efficiency and accuracy.

[0253] Example 10

[0254] Users of portable cleaning devices have placed higher demands on ease of use, safety, and versatility. Traditional cleaning devices rely heavily on basic controls and interfaces, failing to effectively prevent misoperation and improve cleaning efficiency. To this end, this application proposes an improved portable dust removal device that integrates multiple control and display components and features a unique design, aiming to enhance the user experience and device intelligence.

[0255] Please continue reading Figure 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) installed on the second shell 120.

[0256] In some embodiments, the toggle switch 910 is used to prevent accidental touches, ensuring that the device will not be accidentally turned on when not in use. 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 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 of the control switch 920. Therefore, the design of this switch takes into account the user's natural operation and convenience, so that the user does not need to worry about accidentally pressing the start button when picking up the device, avoiding unnecessary energy consumption and potential dangers.

[0257] In some embodiments, the control switch 920 is mainly used to control the opening and closing of the portable dust removal device 10 and to adjust the suction level. The switch allows users to quickly switch suction levels and turn the device on / off to adapt to different operational purposes through a unique control design, thereby providing a more flexible solution. For example, when the user 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 presses the control switch 920, the portable dust removal device 10 will switch from the current level of suction level to the next level of suction level; or; when the user continuously presses the control switch 920, the display content on the display screen 930 will change adaptively to show the corresponding display content to the user.
