Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a portable dust removal device that can be both filled and vacuumed. Background Technology

[0002] Vacuum cleaners are widely used cleaning devices in human life and industrial production. The working principle of a vacuum cleaner is to use a drive motor to rotate the blades at high speed, generating a strong airflow within a sealed casing, creating negative pressure, thereby drawing air and the dust and pollutants it carries into the vacuum cleaner.

[0003] Currently, traditional vacuum cleaners mainly consist of a vacuum cleaner main unit and a vacuum nozzle. The front end of the vacuum cleaner main unit has an air intake port and the rear end has an exhaust port. The rear end of the vacuum nozzle is inserted into the air intake port, and the outer wall of the rear end of the vacuum nozzle is tightly sealed to the inner wall of the air intake port. The front end of the vacuum nozzle forms the suction end. When the vacuum cleaner main unit is working, a negative pressure can be generated in the vacuum nozzle, which allows dust to be sucked away by the vacuum nozzle and stored in the dust box located inside the vacuum cleaner main unit.

[0004] However, the aforementioned vacuum cleaners can only perform the function of vacuuming, thus having the drawback of being single-function. Therefore, with the market demand for portable, multi-functional vacuum cleaners gradually increasing, traditional vacuum cleaners are not convenient enough to use. Summary of the Invention

[0005] Therefore, it is necessary to provide a portable dust removal device that can be used for both filling and suction, which can improve ease of use and has the advantages of multiple functions, in order to address the above-mentioned technical problems.

[0006] This application provides a portable dust removal device that can be both charged and sucked up, the portable dust removal device comprising:

[0010] An air nozzle accessory, located at the air outlet and connected to the device to be inflated, is used to inject the airflow generated by the air pressure from the air outlet into the device to be inflated for inflation.

[0011] In one embodiment, the portable dust removal device further includes a mounting assembly fixed within the cavity. The mounting assembly is a cylindrical structure used to fix the air pressure assembly and guide the airflow to the air outlet when the airflow passes through the air pressure assembly.

[0012] In one embodiment, the installation component includes:

[0016] The connecting element is bent along the axial direction of the housing to guide the airflow passing through the air pressure assembly to the air outlet when the portable dust removal device is being inflated.

[0017] In one embodiment, the connecting element is an arc-shaped airflow guide vane; wherein,

[0018] The airflow guide vanes are fixed at a preset tilt angle to the circumferential surface of the mounting base and the inner wall of the mounting cylinder, respectively, so that when the portable dust removal equipment is being inflated, the airflow is guided to the air outlet by the preset tilt angle.

[0019] In one embodiment, the outer contours of both the mounting base and the mounting cover are cylindrical, and a plurality of airflow guide vanes are arranged in a circumferential array on the circumferential surface of the mounting base to provide force support for the mounting base.

[0020] In one embodiment, the air nozzle accessory includes a connecting end and an output end; wherein the air nozzle accessory is fixedly connected to the air outlet via the connecting end in a screw-on manner, and is fixedly connected to the device to be inflated via the output end in a screw-on manner.

[0021] In one embodiment, the snap fastener structure includes:

[0022] A rotary groove is provided at the connection end and the output end of the air nozzle accessory;

[0023] The rotating blocks are respectively disposed on the outer wall of the air outlet and the outer wall of the inflation interface of the device to be inflated;

[0024] Specifically, the air nozzle accessory is fixedly connected to the air outlet by inserting its connecting end into the outer wall of the air outlet and by fastening the locking block into the locking groove; and

[0025] By inserting the output end of the air nozzle accessory into the outer wall of the inflation interface of the device to be inflated, and by fastening the screw block into the screw groove, the air nozzle accessory and the device to be inflated are fixedly connected.

[0026] In one embodiment, the portable dust removal device further includes a filter assembly disposed within the cavity for filtering the airflow drawn into the cavity from the suction port.

[0030] In one embodiment, the portable dust removal device described above includes at least a handheld dust removal pen for wireless handheld use and a suction pump for automatic inflation and suction.

[0031] The aforementioned portable dust removal device, which combines suction and inflation, significantly reduces its size by housing the air pressure component and cleaning accessories within a handheld mini-shell, making it easy to carry and suitable for cleaning needs in various situations. This enhances the device's portability and operability. Furthermore, unlike existing technologies, this solution integrates cleaning accessories and / or air nozzles into the dust removal device through a rational structural design of the suction and air outlet. This allows the device to not only vacuum and clean surfaces but also perform inflation operations simultaneously, offering simple and convenient operation and improving its efficiency to meet multiple cleaning needs.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are only for explaining this application and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all structures. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0047] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0048] The term "and / or" in the embodiments of this application refers to any and all possible combinations including one or more of the associated listed items. It should also be noted that, when used in this specification, "including / comprising" specifies the presence of the stated features, integers, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, elements, and / or components and / or groups thereof, and is intended to cover non-exclusive situations. For example, a product or device comprising a series of units is not limited to the listed units, but may optionally include units not listed, or may optionally include other units inherent to such products or devices.

[0049] Furthermore, although the terms "first," "second," etc., are used repeatedly in this application to describe various components, these components should not be limited by these terms. These terms are only used to distinguish one component from another, not to describe a specific order. For example, a first housing can be called a second housing, and a second housing can be called a first housing; the only difference is the scope they encompass, but it does not depart from the scope of this application. Both the first housing and the second housing are housing accessories configured in portable dust removal equipment, but they are not housing accessories with the same structural design.

[0050] To explain in detail the technical content, technical steps, objectives and effects of this application, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0051] Traditional dust removal equipment typically only has a vacuuming function. In actual use, users often need additional equipment for inflation, which means they need to carry multiple tools when handling different cleaning tasks, increasing inconvenience. Existing portable dust collectors are limited in size and function, failing to meet modern consumers' demands for multifunctionality and portability. Therefore, it is necessary to develop a new portable dust removal device to achieve more efficient cleaning and inflation.

[0052] This invention provides a portable dust removal device 10 that can be used for both charging and suction. Please refer to [link / reference]. Figures 1 to 4 The dust removal device 10 includes a housing 100, a wind pressure assembly 200, a cleaning accessory 300, and / or an air nozzle accessory 400. The housing 100 is a handheld mini-housing housing with an internal cavity 101. The housing 100 has a suction port 102 and an air outlet 103 communicating with the cavity 101. The wind pressure assembly 200 is located within the cavity 101 and generates wind pressure within the cavity 101. The cleaning accessory 300 is located within the cavity 101 and at least partially extends from the suction port 102. It is used to clean surfaces near the suction port 102, and the airflow generated by the wind pressure draws dust particles from the surface to be cleaned into the cavity 101 through the suction port 102 for dust removal. The air nozzle accessory 400 is located at the air outlet 103 and connected to the device to be inflated 500. It is used to inject the airflow generated by the air pressure from the air outlet 103 into the device to be inflated 500 for inflation.

[0053] For details regarding the outer casing 100, please refer to [link / reference needed]. Figure 1 and Figure 2The portable dust removal device 10, which can be used for both filling and suction, has a user-friendly, handheld mini housing 100. Its structure is carefully designed to make it compact and easy to carry. Inside the housing 100 is a cleaning chamber 101, forming the basic frame of the dust removal device.

[0054] In some embodiments, such as Figure 1 As shown, the main shape of the dust removal device is presented by the outer shell 100. In order to make it easy for users to hold, the outer shell 100 can be a slender cylindrical shell structure, and its size is also more miniaturized than existing dust removal devices, with a diameter of about 2.5 cm and a length of about 15 cm. That is, the shape and size of the dust removal device are slightly similar to the pen used in daily life, which makes it easier for users to hold and use this small and precise cleaning device.

[0055] In some embodiments, such as Figure 2 As shown, the outer casing 100 has a hollow structure, meaning it contains a cavity 101. One end of the cavity 101 has a suction port 102 connecting to the outside, and the other end has an air outlet 103 connecting to the outside. The suction port 102 is close to the surface to be cleaned, used to suck up debris swept off the surface. The air outlet 103 ensures smooth airflow to expel filtered air, improving the overall cleaning efficiency of the device. Simultaneously, the miniature design of the cavity 101 ensures flexibility during use.

[0056] In some embodiments, the suction port 102 and the air outlet 103 are respectively located at the two ends of the housing 100. The cross-sectional shape of the suction port 102 and the air outlet 103 is circular, and the axes of the suction port 102, the air outlet 103 and the cavity 101 are the same straight line.

[0057] In this embodiment, the cross-sections of the cavity 101, the suction port 102, and the air outlet 103 are circular to ensure uniform suction and consistent external dimensions without differences in the angle of use. Additionally, it maintains a consistent wall thickness for the outer shell 100, thereby ensuring the overall strength of the outer shell 100. In some embodiments, the cross-sectional shape of the cavity 101 can be elliptical or polygonal, and the cross-sections of the suction port 102 and the air outlet 103 can be oblong or rectangular, etc. The positions of the suction port 102 and the air outlet 103 can be offset from the axis of the cavity 101.

[0058] The specific shape and size of the outer shell 100 only need to meet the requirements of being easy for users to hold and being more miniaturized than existing devices. This application does not make specific limitations on it. For example, in other embodiments, the outer shell 100 can be a shell structure with an elliptical cross section, or a cylindrical shape with a relatively short and thick shape and a large diameter. Its specific size can also be other values.

[0059] In this embodiment, the axis of the outer shell 100 is the direction of the central axis of the cylindrical outer shell 100. The airflow direction of the portable dust removal device 10, which can be used for both filling and suction, is parallel to the axis during operation. In other embodiments, when the outer shell 100 is not cylindrical, the axis of the outer shell 100 is the extension direction of the main structure, and the airflow direction is parallel to the axis.

[0060] In some embodiments, continue as follows Figure 2 As shown, the portable dust removal device 10 of this application achieves miniaturization of the outer shell 100 and orderly arrangement of internal components through its unique structural design. For example, from the suction port 102 to the air outlet 103 of the cavity 101, the cleaning accessory 300, the drive source 600, the mounting component 800, the air pressure component 200, the filter component 700, and other components of the portable dust removal device 10 (e.g., battery, air guide cover, etc.) that are adapted to the shape and size can be combined together to form a complete portable dust removal device 10. Among them, the cleaning accessory 300, the drive source 600, the mounting component 800, the air pressure component 200, and the filter component 700 are connected in series in the cavity 101 to form a compact and efficient cleaning system, which can achieve powerful cleaning performance without occupying too much space.

[0061] In some embodiments, each component of the portable dust removal device 10 is detachably connected to the housing 100 or other components, making the assembly and subsequent disassembly of each component more convenient and efficient.

[0062] Regarding the wind pressure component 200, continue as follows Figure 2 As shown, the wind pressure assembly 200 is the core power component of the dust removal equipment 10, responsible for providing the power required to generate airflow and suction. The wind pressure assembly 200 is driven by the wind pressure motor 210, which can convert electrical energy into mechanical energy to drive the centrifugal fan blade 220 to rotate, thereby generating wind pressure within the cavity 101.

[0063] In some embodiments, the air pressure assembly 200 is located inside the cavity 101 and is disposed after the filter assembly 700. It is used to generate air pressure inside the cavity 101, and its function is to suck the debris on the surface to be cleaned into the cavity 101 through the suction port. This function is effectively implemented in a small space and enhances the dust suction capability of the device.

[0064] The wind pressure assembly 200 may include a wind pressure motor 210 and a centrifugal fan blade 220. The wind pressure motor 210 is fixedly installed on the housing 100 and housed in the cavity 101. The centrifugal fan blade 220 is sleeved on the power shaft 211 of the wind pressure motor 210. Thus, the wind pressure motor 210 can drive the centrifugal fan blade 220 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 dust suction port 102.

[0065] For cleaning accessories 300, such as Figure 3 As shown, one end of the cleaning accessory 300 is a mounting end 310, used to mount on the output shaft 610 of the drive source 600 to realize power transmission between the cleaning accessory 300 and the drive source 600; the other end is a cleaning end 320, used to clean the surface to be cleaned under the drive of the drive source 600. Specifically, the cleaning end 320 of the cleaning accessory 300 cleans the surface to be cleaned by moving under the drive of the output shaft 610.

[0066] In some embodiments, the mounting end 310 is provided with a mounting shaft 311 with a regular hexagonal cross section on the side opposite to the cleaning end 320, and the corresponding output shaft 610 of the drive source 600 is also provided with a regular hexagonal mounting hole (not shown in the figure). The mounting shaft 311 is installed on the output shaft 610 in a plug-in manner to realize the power transmission between the cleaning accessory 300 and the drive source 600, thereby ensuring that the cleaning accessory 300 can operate stably and withstand the dynamic forces.

[0067] In some embodiments, the mounting shaft 311 can be made of magnetic material, and the end of the output shaft 610 of the drive source 600 is also provided with magnetic material, and the magnetism of the two is opposite. The cleaning accessory 300 is installed by plugging in and also detached by magnetic attraction. Compared with the tight plugging installation method, the magnetic assembly process is more effortless and easy, and has a feeling of being properly assembled.

[0068] In some embodiments, the mounting end 310 can be a solid cylindrical ring structure, the cleaning end 320 is fixed to the side of the base 210 near the suction port 102, and the diameter of the base 210 is smaller than that of the suction port 102. The airflow carrying impurities is drawn into the suction port 102 from the outer circumference of the mounting end 310.

[0069] The mounting end 310 features a solid cylindrical ring structure, providing excellent stability and load-bearing capacity to withstand kinetic energy during cleaning and facilitating connection to the vacuuming system. Furthermore, the diameter of the base 210 is designed to be smaller than the diameter of the suction port 102, ensuring effective integration between the mounting end 310 and the suction port 102, guaranteeing unobstructed airflow and providing favorable conditions for subsequent vacuuming.

[0070] Optionally, the surface to be cleaned can be a flat surface or an uneven surface, a hard surface or a soft surface, etc. Furthermore, users can replace the corresponding cleaning accessory 300 to clean different types of surfaces, so as to achieve effective cleaning of the surface. Therefore, the cleaning accessory 300 is ingeniously designed and can flexibly meet the cleaning needs of different surfaces and environments.

[0071] In some embodiments, in order to ensure the strength of the mounting end 310 of the cleaning accessory 300 and to prevent the excessively long mounting end 310 and output shaft 610 from deforming or being damaged under stress, the cleaning accessory 300 may be configured to partially extend out of the cavity 101 from the suction port 102. However, in other embodiments, the mounting end 310 may not extend into the suction port 102, that is, the cleaning accessory 300 may be configured to fully extend out of the suction port 102. In this case, part of the output shaft 610 extends out of the suction port 102, and the mounting end 310 and the output shaft 610 are fixedly assembled.

[0072] In some embodiments, continue as follows Figure 2 As shown, the drive source 600 is installed inside the cavity 101 and positioned after the cleaning accessory 300. It is responsible for driving the movement of the cleaning accessory 300 to achieve the cleaning capability of the device. The drive source 600 is a detachable and replaceable drive motor, which may be a rotary motor, a vibration motor, or an ultrasonic generator, etc.

[0073] For example, the drive source 600 can be a rotary motor, which drives the cleaning accessory 300 to rotate and clean the surface to be cleaned. The rotary motor can be used to clean oil stains or fingerprints on the surface, providing smooth rotational power to the cleaning accessory 300, ensuring effective contact between the accessory and the surface, thereby efficiently removing the attached dirt without damaging the surface.

[0074] For example, the drive source 600 can be a vibration motor, which drives the cleaning accessory 300 by vibration, so that the cleaning accessory 300 vibrates and cleans the surface to be cleaned. The vibration motor can be used to clean dust adhering to the surface. The fine vibration it generates can effectively loosen and shake off the dust adhering to the surface, enhancing the cleaning effect, especially when dealing with fabrics or uneven surfaces.

[0075] For certain scenarios, such as deep cleaning of stubborn stains or fine particles, the drive source 600 can be an ultrasonic generator, which uses high-frequency sound waves to achieve a deep cleaning effect on the surface.

[0076] The 600 drive source offers a variety of options, including rotary motors, vibrating motors, and ultrasonic generators, enabling it to provide optimal solutions for different cleaning needs, thus meeting the cleaning requirements of homes, industries, and special environments.

[0077] In some embodiments, continue as follows Figure 2 As shown, the portable dust removal device 10 also includes a filter assembly 700, which is disposed inside the cavity 101 and is used to filter the airflow drawn into the cavity 101 from the suction port 102.

[0078] Specifically, the filter assembly 700 is sequentially arranged in the cavity and located between the air pressure assembly 200 and the drive source 600. Its function is to effectively filter the garbage entering the cavity 101, ensure the cleaning effect, and prevent the garbage from flowing back into the environment, thereby improving the safety of the user.

[0079] The filter component 700 can be made of a microporous ceramic filter for filtering larger dust particles; or a metal mesh, which is low in cost and has a good filtration effect; or a sponge filter layer to filter out larger substances in the air; or a HEPA filter layer to filter out smaller particles, and the filtration effect is better when used in combination.

[0080] In a specific implementation scenario, when the portable dust removal device 10 is working, the drive source 600 first drives the cleaning accessory 300 to move, so that the cleaning accessory 300 sweeps off the garbage on the surface to be cleaned; then the wind pressure assembly 200 drives the centrifugal fan blade 210 to rotate, thereby generating wind pressure in the cavity 101, so as to suck the garbage on the surface to be cleaned into the cavity 101 through the dust suction port 102; finally, the filter assembly 700 filters the air carrying garbage in the suction cavity 101, so as to discharge the filtered clean air from the air outlet 103.

[0081] For valve parts 400, such as Figure 4As shown, the air nozzle accessory 400 is a component used to connect to the device to be inflated 500 (such as a balloon, tire, air mattress, etc.). The main function of the air nozzle accessory 400 is to inject the airflow generated by the air pressure assembly 200 from the air outlet 103 into the device to be inflated 500 for inflation, and to prevent gas leakage. The air nozzle accessory 400 can be available in different sizes and types to suit different inflation needs.

[0082] Specifically, continue as Figure 4 As shown, the types of valve accessories 400 can include the following: ① Flange valves, used for inflating tires, are usually made of metal, durable and leak-proof. ② Plastic valves, mostly used for balloons and small inflatable toys, lightweight and easy to use. ③ Universal valves, suitable for various products, usually with different adapters to accommodate different inflation needs.

[0083] In some embodiments, the valve fitting 400 can be designed in various shapes and sizes to accommodate different models and types of air pumps and different inflatable objects, such as tires, balloons, lifeboats, etc. Furthermore, the valve fitting 400 can be made of wear-resistant materials (such as plastic or metal) to ensure its durability and elasticity under high pressure, preventing breakage or deformation during use. Its well-sealed design effectively prevents gas leakage, improves inflation efficiency, and reduces air waste.

[0084] In some embodiments, the air nozzle accessory 400 specifically includes the following application functions: ① Inflation function, used to deliver gas (i.e., airflow) from the air outlet 103 to the device to be inflated 500 for rapid inflation. ② Deflating function, the air nozzle accessory 400 has a deflation function, which can regulate the gas flow to facilitate deflation of the target item. ③ Connection function, the air nozzle accessory 400 can securely connect the air outlet 103 and the device to be inflated 500, ensuring that it will not detach during inflation. ④ Airflow control function, the air nozzle accessory 400 is designed with a valve or switch, which can be used to control the inflation speed and airflow. ⑤ Adaptability to different air pressures function, the air nozzle accessory 400 can adapt to different air pressure requirements, thus being suitable for various inflation scenarios.

[0085] In a specific implementation scenario, when the portable dust removal device 10 of this application, which can be used for both filling and suction, is equipped with a cleaning accessory 300 at the suction port 102 of the outer casing 100, it cleans the surface to be cleaned near the suction port through the cleaning accessory 300, and the airflow generated by the wind pressure component 200 sucks the dust particles on the surface to be cleaned from the suction port 102 into the cavity 101 of the outer casing 100 for dust removal; or, when the air outlet 103 of the outer casing 100 is equipped with an air nozzle accessory 400, it is connected to the inflation device 500 through the air nozzle accessory 400 to inject the airflow generated by the wind pressure component 200 into the inflation device 500 for inflation.

[0086] In one embodiment, the portable dust removal device 10 of this application, which can be used for both inflation and suction, includes at least a handheld dust removal pen for wireless handheld use and an inflation / suction pump for automatic inflation and suction.

[0087] In some embodiments, this handheld dust removal pen features a wireless design, is lightweight and portable, and is suitable for handheld use. Its ergonomic design allows for extended use with reduced fatigue. This dust removal pen is suitable for cleaning and removing dust and dirt from desktops, keyboards, windowsills, and other confined areas. It can also be used for inflating items such as tires, balloons, and lifeboats. The wireless design allows for easy movement, enhancing the convenience and flexibility of operation.

[0088] In some embodiments, the automatic air pump has an intelligent on / off function, which can autonomously clean or inflate a preset fixed area according to a preset working mode. During operation, it can be remotely controlled by the user or automatically turned on or off based on environmental conditions, thereby improving user convenience. Simultaneously, the air pump can connect to other smart devices of the user to achieve remote control and timed cleaning functions.

[0089] The technical advantages of the above solution are as follows: Firstly, by housing the wind pressure components and cleaning accessories within a handheld mini-shell, the physical size of the dust removal equipment is greatly reduced, making the equipment easy to carry and suitable for cleaning needs in various situations, thereby improving the portability and operability of the dust removal equipment. Secondly, by differentiating itself from existing technologies, this solution integrates cleaning accessories and / or air nozzle accessories into the dust removal equipment through a reasonable structural design of the suction port and air outlet. This allows the dust removal equipment to not only perform surface cleaning but also perform inflation operations using the same device, with simple and convenient operation, thereby improving the efficiency of the dust removal equipment and meeting multiple cleaning needs.

[0090] Those skilled in the art will understand that Figures 1 to 4The portable dust removal device shown in the figure is merely a block diagram of a part of the structure related to the present application and does not constitute a limitation on the dust removal device used thereon. The specific wind pressure component may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements.

[0091] Please continue reading. Figure 1 and Figure 2 For the outer shell 100 in the above embodiment, the outer shell 100 further includes a detachable first shell 110 and a second shell 120, which together enclose a cavity 101; wherein, the portion of the cavity 101 within the first shell 110 is divided into a dust chamber 101a, and the portion of the cavity 101 within the second shell 120 is divided into an installation chamber 101b. Specifically, the filter assembly 700 is installed within the first shell 110, dividing the cavity 101 into the installation chamber 101b and the dust chamber 101a; the wind pressure assembly 200 is installed within the installation chamber 101b, and the suction port 102 is located at the end of the first shell 110 away from the second shell 120, and the air outlet 103 is located at the end of the second shell 120 away from the first shell 110, or the air outlet 103 is located on the side of the second shell 120 near the wind pressure assembly 200.

[0092] In one embodiment, continue as follows Figure 1 As shown, the structure of the outer casing 100 includes a detachable first casing 110 and a second casing 120, which together enclose a cavity 101. This structural design aims to improve the maintainability and ease of operation of the equipment, while also allowing users to easily disassemble it for cleaning and maintenance.

[0093] Furthermore, inside the cavity 101, a filter assembly 700 is installed within the first housing 110, which divides the cavity 101 into two areas: a mounting cavity 101b and a dust cavity 101a. This design makes the airflow inside the device more orderly and effectively separates impurities from clean air.

[0094] Furthermore, the suction port 102 is located at the end of the first housing 110 away from the second housing 120 to ensure that dirt and debris can be quickly sucked in during the cleaning process. At the same time, the clean airflow passing through the filter assembly 700 will be formed in the mounting cavity 101b and finally discharged through the air outlet 103 to ensure that the released air is clean and unpolluted.

[0095] The filter assembly 700 optimizes airflow direction, ensuring that debris on the surface to be cleaned, after being drawn into the cavity 101 through the suction port 102, quickly enters the dust chamber 101a. This design effectively captures and stores impurities, significantly reducing the risk of them flowing back into the environment with the airflow. Simultaneously, the filtered clean airflow smoothly exits through the mounting cavity 101b to the air outlet, thereby improving overall cleaning efficiency.

[0096] In some embodiments, the first housing 110 and the second housing 120 are both elongated cylindrical shell structures with a diameter of 2.5 cm. The first housing 110 and the second housing 120 are fixed by screw connection. In the assembled state, the length of the outer shell 100 is approximately 15 cm. The dust chamber 101a and the suction port 102 inside the housing are connected and coaxially arranged. The mounting cavity 101b and the dust chamber 101a are cylindrical with the same cross-sectional shape, and the suction port 102 has a circular cross-sectional shape.

[0097] The circular cross-sections of the mounting cavity 101b, dust cavity 101a, and suction port 102 are designed for uniform suction, consistent aesthetics, and consistent thickness of the outer casing 100. However, the specific shapes of the mounting cavity 101b, dust cavity 101a, and suction port 102 can also be other shapes. For example, the cross-sectional shapes of the mounting cavity 101b and dust cavity 101a can be elliptical or polygonal, and the cross-section of the suction port 102 can be oblong or rectangular, etc. Furthermore, the position of the suction port 102 can be offset from the axis of the dust cavity 101a. In other embodiments, the first housing 110 and the second housing 120 can also be fixed by snap-fit ​​or plug-in connection, or opened and closed by a pivot connection and locking structure; no specific limitations are made here.

[0098] Furthermore, in this embodiment, the airflow direction refers to the direction in which the gas flows within the cavity 101. This airflow direction is approximately the axial direction of the first housing 110 and the second housing 120. At certain locations within the cavity 101, the airflow direction may slightly deviate radially due to the obstruction of the air guiding structure and internal components. Moreover, when defining the direction, the airflow direction described refers to the axial direction of the first housing 110 and the second housing 120. The outer contours of the first housing 110 and the second housing 120 are cylindrical, and their axes are the central axes of the corresponding cylinders.

[0099] The technical advantages of the above solution are as follows: by dividing the housing cavity into an installation chamber and a dust chamber, more efficient waste separation and airflow optimization are achieved. When the clean airflow passes through the filter assembly, impurities are effectively isolated, and the purified air is safely discharged to the air pressure assembly 200. Furthermore, this housing structure improves the stability and cleaning performance of the equipment, not only optimizing the cleaning effect but also significantly enhancing the user experience.

[0100] As a further optimization of the above embodiment, the number of cavities 101 is preferably two, namely a dust cavity 101a and a mounting cavity 101b. The suction port 102 is connected to the dust cavity 101a, and the air outlet 103 is connected to the mounting cavity 101b. The dust cavity 101a and the mounting cavity 101b are interconnected through a vortex flow channel. The impeller of the centrifugal blade 220 is mounted in the mounting cavity 101b. Specifically, driven by the motor, the centrifugal blade 220 and the drive source 600 rotate synchronously. At this time, the centrifugal blade 220 draws external gas into the dust cavity 101a through the suction port 102, and then draws the gas entering the dust cavity 101a into the mounting cavity 101b through the vortex flow channel, and discharges it from the air outlet 103.

[0101] This embodiment, by setting up an installation cavity 101b that communicates with the dust chamber 101a, and adding a drive source 600 inside it that rotates synchronously with the centrifugal blades 220, can accelerate the flow of gas within the installation cavity 101b, thereby increasing the pressure of the gas discharged from the outlet 103. Furthermore, the higher the gas flow velocity within the installation cavity 101b, the lower its pressure, and more gas from the dust chamber 101a will flow into the installation cavity 101b due to the pressure difference. That is, the pressure within the dust chamber 101a will decrease more rapidly, increasing the speed at which it draws gas from the outside, further increasing the pressure of the gas discharged from the outlet 103, and improving the inflation efficiency.

[0102] It is worth mentioning that the dust chamber 101a and the mounting chamber 101b are arranged correspondingly at the front and rear, and preferably, the suction port 102 is located on the front end face and communicates with the dust chamber 101a corresponding to the front end face. The air outlet 103 is located on the side wall of the housing 100 and adjacent to the rear end face, and communicates with the mounting chamber 101b corresponding to the rear end face.

[0103] In this embodiment, the vortex flow channel has a first flow channel opening located in the dust chamber 101a and a second flow channel opening located in the mounting chamber 101b. The first flow channel opening is located on one side of the dust chamber 101a and is connected to the dust chamber 101a. Correspondingly, the second flow channel opening is located at the upper end of the mounting chamber 101b and is connected to the mounting chamber 101b.

[0104] Since the drive source 600 in the dust chamber 101a rotates, it drives the gas in the dust chamber 101a to rotate as well. Due to the influence of centrifugal force during rotation, the first flow channel opening connected to the dust chamber 101a is located on one side of the dust chamber 101a. This allows the gas in the dust chamber 101a to be quickly drawn into the mounting cavity 101b through the vortex flow channel. Furthermore, placing the second flow channel opening connected to the mounting cavity 101b at the front end of the mounting cavity 101b is more conducive to the centrifugal blades 220 further accelerating the gas flow rate drawn into the mounting cavity 101b, thereby increasing the pressure of the gas discharged from the outlet 103 and improving the inflation efficiency.

[0105] Preferably, the dust chamber 101a is provided with a partition, one end of which is connected to the housing 100, and the other end of which forms a gap with the housing 100. A rotating station is formed between the partition and the dust chamber 101a, the outline of which is adapted to the drive source 600 for rotation of the drive source 600. At this time, a first flow channel opening is formed in the area of ​​the dust chamber 101a different from the rotating station, and the gap allows the rotating station and the first flow channel opening to communicate with each other.

[0106] In actual production, the position of the gap setting should be flexibly set according to the rotation direction of the drive source 600, as long as it can ensure that the gas in the dust chamber 101a can enter the first flow channel more quickly and smoothly.

[0107] Furthermore, in this embodiment, a partition is provided to divide the dust chamber 101a into a rotating station and a first flow channel opening. Thus, when the drive source 600 rotates the gas within the dust chamber 101a, no gas that has not undergone rotational acceleration will directly escape into the first flow channel opening, effectively ensuring its suction effect. Moreover, the contour of the rotating station is compatible with the drive source 600, allowing the drive source 600 to rotate all the gas within the rotating station to the maximum extent, improving its efficiency in extracting external gas.

[0108] Based on this, a first guide slope is provided at one end of the baffle corresponding to the gap, and a second guide slope is provided at the top of the dust chamber 101a, corresponding to the position of the first flow channel opening. The first and second guide slopes are used together to guide the gas in the dust chamber 101a into the interior of the vortex flow channel through the first flow channel opening.

[0109] In this embodiment, the first and second guide slopes ensure that the gas flow rate in the dust chamber 101a is not affected by collisions when it is pumped to the mounting chamber 101b. Furthermore, the first and second guide slopes guide more gas smoothly into the vortex channel, improving inflation efficiency.

[0110] In actual production, the second guide slope can be a hollow block structure, which is preferably fixed on the upper cover, but can also be fixed on the side wall of the dust chamber 101a. Its specific structure and setting position can be flexibly changed according to the actual situation, and are not limited here. Moreover, the surfaces of the first and second guide slopes used for guiding flow can be set as arc surfaces or slopes, etc., all of which are within the protection scope of this patent.

[0111] In a preferred embodiment, a flow guide ring 104 is provided between the dust chamber 101a and the mounting chamber 101b, and the bottom wall of the dust chamber 101a, the top wall of the mounting chamber 101b and the flow guide ring 104 together form a vortex flow channel.

[0112] When gas is drawn from dust chamber 101a to mounting chamber 101b, the vortex flow channel ensures that all the drawn gas is concentrated in the vortex flow channel and drawn to the mounting chamber 101b along its trajectory, preventing gas escape. Specifically, to ensure that the flow rate of gas is not affected during the process of being drawn from dust chamber 101a to mounting chamber 101b, the guide ring 104 can be bent and extended from the inner wall of housing 100 along the rotation direction of drive source 600 toward the middle position of housing 100, so as to guide and transport the gas in the first flow channel opening to the second flow channel opening.

[0113] In this embodiment, the drive source 600 rotates counterclockwise as an example. In this case, the guide ring 104 bends and extends counterclockwise from the inner wall of the housing 100 toward the center of the housing 100. In actual production, the drive source 600 can also rotate clockwise. In this case, the guide ring 104 bends and extends clockwise from the inner wall of the housing 100 toward the center of the housing 100. This is not a limitation.

[0114] Furthermore, the curved extension of the guide ring 104 further reduces the collision between the gas and the sidewall during the pumping process, ensuring that the gas flow rate is not affected. This embodiment does not impose any restrictions on the specific structure of the guide ring 104; it can be flexibly set according to actual usage requirements, all of which are within the scope of this patent.

[0115] In some embodiments, such as Figure 2 As shown, the portable dust removal device 10 also includes a mounting component 800, which is fixed inside the cavity 101. The mounting component 800 has a cylindrical structure and is used to fix the air pressure component 200 and guide the airflow to the air outlet 103 when the airflow flows through the air pressure component 200.

[0116] Specifically, the mounting assembly 800 is fixed inside the cavity 101, and the mounting assembly 800 is a cylindrical structure used to cover and fix the air compressor motor 210, and to guide the airflow to the air outlet 103 when the intake airflow flows through the air compressor motor 210.

[0117] In one embodiment, such as Figure 5 As shown, the mounting assembly 800 specifically includes: a mounting base 810, a mounting cover 820, and a connecting element 830. The connecting element 830 is bent in the axial direction of the housing 100 to guide the airflow passing through the air pressure assembly 200 to the air outlet 103 when the portable dust removal device 10 is being inflated.

[0118] In some embodiments, the mounting base 810 is a cylindrical cavity wall structure without a top cover, that is, the mounting base 810 has a first opening 801 on the side near the dust suction port 102, the first opening 801 is used to insert and fix the wind pressure motor 210, and the mounting base 810 and the housing 100 are coaxially arranged.

[0119] In one embodiment, continue as follows Figure 5 As shown, the mounting cover 820 is also a cylindrical structure, which can be plugged into the mounting base 810 to enclose and completely cover the wind turbine motor 210, thereby providing electromagnetic shielding for the wind turbine motor 210 and ensuring the electrical stability of the wind turbine motor 210.

[0120] The air compressor motor 210 is mounted by the mounting base 810 and the mounting cover 820, ensuring the motor is stable and fully protected. This structural design effectively resists damage to the motor from the external environment while providing good support.

[0121] In one embodiment, the mounting assembly 800 may further include a mounting cylinder 840 fixed to the inner wall of the cavity 101 for accommodating the wind turbine motor 210 and the centrifugal fan blade 220.

[0122] Specifically, such as Figure 5 and Figure 6 As shown, the mounting cylinder 840 is a cylindrical shell structure without a top cover. The mounting cylinder 840 has a second opening 802 on the side near the dust inlet 102. The second opening 802 can have a receiving cavity to accommodate the entire wind compressor motor 210 and centrifugal fan blade 220 starting from the second opening 802. The connecting element 830 is perpendicular to the axis of the outer shell 100, with one end connected to the inner wall of the mounting cylinder 840 and the other end connected to the mounting base 810, so as to realize the installation of the wind compressor motor 210 and centrifugal fan blade 220 in the cavity 101.

[0123] In some embodiments, such as Figure 6 As shown, the connecting element 830 is a stiffener structure, which is bent along the axial direction of the outer shell 100, and one end of it is connected to the inner wall of the mounting cylinder 840, and the other end is connected to the mounting base 810, so as to realize the installation of the wind pressure motor 210 on the outer shell 100.

[0124] The curved structure design of the connecting element 830 helps guide the gas flow to a smoother path, reducing airflow resistance. This optimized design ensures more efficient gas flow after passing through the wind pressure motor 210, reduces the risk of airflow convergence and eddy current generation, and improves the utilization rate of wind pressure.

[0125] In another embodiment, for the mounting component 800, in order to simplify the structure of the housing 100 and reduce the manufacturing difficulty of the housing 100, the mounting component 800 can be an independent component, that is, the wind pressure motor 210 and the centrifugal fan blade 220 are mounted on the mounting component 800 and then installed together in the housing 100. However, in some other embodiments, the mounting component 800 can also be integrally formed with the housing 100, which is not specifically limited here.

[0126] In some embodiments, the mounting assembly 800 may have a receiving cavity for accommodating the entire wind compressor motor 210 and centrifugal fan blade 220 starting from the second opening 802. That is, the second opening 802 of the mounting assembly 800 and the wind compressor motor 210 are connected to each other on the side of the airflow direction near the dust suction port 102, and the mounting assembly 800 is arranged around the inner wall of the housing 100 to divide and form a mounting space in the cavity 101 for mounting the wind compressor motor 210.

[0127] In one embodiment, the second opening 802 of the mounting component 800 and the wind pressure motor 210 are connected on the side of the airflow direction near the suction port 102. This area is a hollow cylindrical structure, so that the mounting component 800 and the wind pressure motor 210 can be fitted together.

[0128] The mounting component 800's fixing and encasing design ensures the stability of the air compressor motor 210 during operation, reducing operational instability caused by vibration and improving the overall operational safety and reliability of the dust removal equipment 10. Furthermore, the structural design of the mounting component 800 allows the centrifugal fan blades 220 to connect directly and quickly to the air compressor motor 210, ensuring efficient air pressure generation. This structure reduces airflow resistance, improves the equipment's air pressure efficiency, and thus enhances the dust collection effect.

[0129] In one implementation scenario, by tightly integrating the wind pressure motor 210 and the centrifugal fan blade 220, the structure is simplified and assembly efficiency is improved. Simultaneously, the powerful wind pressure generates more stable airflow, ensuring maximum cleaning effectiveness. During use, the powerful wind pressure allows users to clean various surfaces quickly, thereby increasing user satisfaction.

[0130] The technical advantages of the above solution are as follows: Through the reasonable structural design of the installation component cylinder structure, the installation of the wind turbine motor and other components can be made easier, thereby improving the assembly efficiency of the dust removal equipment. Furthermore, by designing the connecting elements to be curved in the axial direction of the outer shell, the intake airflow is guided to a smoother path, thereby reducing the resistance problem caused by changes in airflow direction and improving the smoothness of gas flow.

[0131] In one embodiment, the connecting element 830 in the mounting assembly 800 is an arc-shaped airflow guide vane; wherein, the two sides of the airflow guide vane are fixed to the circumferential surface of the mounting base 810 and the inner wall of the mounting cylinder 840 respectively at a preset tilt angle, so that when the portable dust removal device 10 is inflated, the airflow is guided to the air outlet 103 by the preset tilt angle.

[0132] Specifically, such as Figure 6 As shown, the overall shape of the airflow guide vane is arc-shaped, forming a streamlined design that helps the airflow flow smoothly along a predetermined path. Therefore, this arc-shaped structure can effectively reduce the generation of vortices when the airflow turns, reducing airflow resistance and energy loss.

[0133] Furthermore, the two sides of the airflow guide vane are fixed to the circumferential surface of the mounting base 810 and the inner wall of the mounting cylinder 840 respectively at preset tilt angles (such as 30°, 45°, 60°, etc.). This tilt angle design ensures that when the airflow is drawn in, it can flow in a specific direction under the guidance of the guide vane, thereby increasing the contact area between the airflow and the inhaled gas and improving the inflation effect.

[0134] Furthermore, the airflow guide vane can be securely fixed between the mounting base 810 and the mounting cylinder 840 using appropriate fixing methods (such as screws, adhesives, or clips), thereby ensuring that the guide vane does not shift or fall off during use, thus guaranteeing the effectiveness and stability of its function.

[0135] In one embodiment, the outer contours of the mounting base 810 and the mounting cover 320 are both cylindrical, and multiple airflow guide vanes are arranged in a circumferential array on the circumferential surface of the mounting base 810 to provide force support for the mounting base 810.

[0136] Specifically, please refer to Figure 7 The connecting element 830 is bent in the axial direction of the second housing 120, that is, the connecting element 830 is arc-shaped, and there are 11 connecting elements 830. The 11 connecting elements 830 are respectively arranged around the outer circumference of the mounting base 810, and the arc-shaped arrangement of each connecting element 830 can increase the contact area while guiding the gas to reduce the resistance to airflow.

[0137] In some embodiments, the connecting element 830 can be a flat plate structure or a block structure with a large cross-sectional area, with its two ends connected to the mounting cylinder 840 and the mounting base 810 respectively, so as to fix the mounting base 810 in the mounting cylinder 840. In other embodiments, the number of connecting elements 830 can be 2, 3 or 6, etc., with multiple connecting elements 830 arranged around the mounting base 810, or the number of connecting elements 223 can be set to one while ensuring the installation strength of the mounting base 810.

[0138] In order to fit the shape of the wind pressure motor 210 and the mounting cavity 101b, the outer contours of the mounting cavity 101b, the mounting base 810 and the mounting cylinder 840 are set in a cylindrical manner to optimize space and keep the distance between the mounting cylinder 840 and the inner wall of the second housing 120 consistent, so as to avoid uneven wind pressure and thus cause resistance. In other embodiments, the wind pressure motor 210 can also be fixedly installed on the second housing 120 with other structures to achieve the fixed installation of the wind pressure motor 210.

[0139] In one embodiment, the wind turbine motor 210 is enclosed and installed by the mounting base 810 and the mounting cover 320. Then, the connecting element 830 is connected to the circumferential surface of the mounting base 810 and the inner wall of the mounting cylinder 840 at a preset tilt angle in the axial direction of the second housing 120. Finally, the mounting cylinder 840 is attached to the second housing 120 to enclose and install the entire wind turbine motor 210, so as to realize the installation of the wind turbine motor 210 in the cavity 101.

[0140] The beneficial effects of the above embodiments are as follows: by designing the connecting element as an arc-shaped airflow guide vane, the shortcomings of traditional dust removal equipment in airflow guidance are effectively solved. The inclined design of the airflow guide vane not only smoothly guides the airflow but also captures more dust particles in the airflow, thereby improving the working efficiency and performance of the dust removal equipment.

[0141] In one embodiment, such as Figure 8 As shown, the air nozzle accessory 400 includes a connecting end 410 and an output end 420; wherein, the air nozzle accessory 400 is fixedly connected to the air outlet 103 via the connecting end 410 in a screw-on structure, and is fixedly connected to the device to be inflated 500 via the output end 420 in a screw-on structure.

[0142] Specifically, continue as Figure 8 As shown, the screw fastener structure includes a screw fastener groove 401 and a screw fastener block 402. The screw fastener groove 401 is respectively disposed on the connection end 410 and the output end 420 of the air nozzle accessory 400, and the screw fastener block 402 is respectively disposed on the outer wall or inner wall of the air outlet 103, and on the outer wall or inner wall of the inflation interface of the inflation device 500.

[0143] In some embodiments, the air nozzle accessory 400 is fixedly connected to the air outlet 103 by inserting the connecting end 410 of the air nozzle accessory 400 into the outer or inner wall of the air outlet 103 and by fastening the locking block 402 into the locking groove 401; and the air nozzle accessory 400 is fixedly connected to the air outlet 103 by inserting the output end 420 of the air nozzle accessory 400 into the outer or inner wall of the inflation interface of the device to be inflated 500 and by fastening the locking block 402 into the locking groove 401.

[0144] In a specific implementation scenario, a locking groove 401 is provided on the side wall of the air outlet 103. The connecting end 410 of the air nozzle accessory 400 is inserted into the locking groove 401. Several locking blocks 402 are provided on the inner wall of the locking groove 401 in a circumferentially evenly distributed manner. The outer wall of the front end of the air nozzle accessory 400 is provided with a locking groove 401 corresponding to each locking block 402. When the front end of the air nozzle accessory 400 is inserted into the locking groove 401 and the air nozzle accessory 400 rotates relative to the portable dust removal device 10, each locking block 402 is used to engage with the corresponding locking groove 401 to lock the air nozzle accessory 400 and the portable dust removal device 10.

[0145] With this structure, when the connecting end 410 of the air nozzle accessory 400 is inserted into the locking groove 401 and the air nozzle accessory 400 rotates relative to the portable dust removal device 10, each locking block 402 can be engaged into the corresponding locking groove 401 to lock the air nozzle accessory 400 and the portable dust removal device 10. When the air nozzle accessory 400 needs to be disengaged from the portable dust removal device 10, the air nozzle accessory 400 is rotated in the opposite direction relative to the portable dust removal device 10. At this time, each locking groove 401 can disengage from the corresponding locking block 402, and then the connecting end 410 of the air nozzle accessory 400 can be pulled out from the locking groove 401. Thus, with the above structure, the air nozzle accessory 400 and the portable dust removal device 10 are easy to assemble and disassemble.

[0146] In some embodiments, such as Figure 9 As shown, the air nozzle accessory 400 may include a first air nozzle 400a, a second air nozzle 400b, and a third air nozzle 400c. The connecting ends 410 of the first air nozzle 400a, the second air nozzle 400b, and the third air nozzle 400c have the same diameter. The output ends 420 of the first air nozzle 400a, the second air nozzle 400b, and the third air nozzle 400c have successively larger diameters and are smaller than the diameter of their respective connecting ends 410.

[0147] Among them, the first air nozzle 400a, the second air nozzle 400b, and the third air nozzle 400c are respectively large, medium, and small air nozzles. The small air nozzle can be used to inflate, for example, swimming rings and yoga balls with the portable dust removal device 10. The medium air nozzle can be used to inflate, for example, air mattresses with the portable dust removal device 10. The large air nozzle can be used to inflate, for example, inflatable boats with the portable dust removal device 10. In addition, the air nozzle assembly 400 and the portable dust removal device 10 can also meet the high-pressure inflation needs of car tires, balloons, and basketballs and soccer balls.

[0148] In other embodiments, in addition to being able to connect to the air outlet 103 via a snap fastener structure to exhaust air outward, the air nozzle accessory 400 can also be used to draw air inward when it is connected to the air inlet 102 via a snap fastener structure.

[0149] Specifically, the screw fastener structure may also include two sets of identical screw fastener grooves 401 and screw fastener blocks 402. The screw fastener grooves 401 are evenly arranged on the outer walls of the connecting ends of the first air nozzle 400a, the second air nozzle 400b, and the third air nozzle 400c, respectively. The screw fastener blocks 402 are evenly arranged on the inner walls of the air inlet 102 and the air outlet 103, respectively, and correspond to the screw fastener grooves 401. The diameter of the connecting port of the first air nozzle 400a, the second air nozzle 400b, and the third air nozzle 400c is smaller than the diameter of the air inlet 102 and the air outlet 103, and the diameter of the air inlet 102 and the air outlet 103 is the same.

[0150] In specific implementation, the connecting ends 410 of the first air nozzle 400a, the second air nozzle 400b, and the third air nozzle 400c can be inserted into the air inlet 102 and the air outlet 103 respectively, and the first air nozzle 400a, the second air nozzle 400b, and the third air nozzle 400c can be rotated and snapped into the air inlet 102 and the air outlet 103 respectively by fastening the swivel block 402 into the swivel groove 401.

[0151] Furthermore, the output end 420 of the third air nozzle 400c can be inserted into the connection end 410 of the second air nozzle 400b, and the output end 420 of the second air nozzle 400b can be inserted into the connection end 410 of the first air nozzle 400a, thereby realizing the sequential stacking of the three.

[0152] To facilitate increasing the negative pressure during vacuuming or inflation operations in this embodiment, the nozzle accessory 400 may further include a silicone suction nozzle (not shown). The smaller diameter end of the silicone suction nozzle can be fitted onto the outside of the output end 420 of the first nozzle 400a, and the smaller diameter end of the silicone suction nozzle can be inserted into the connection end 410 of the first nozzle 400a, thereby enabling the two to be stacked. This stacking arrangement makes the nozzle assembly 400 more compact, facilitating storage and portability.

[0153] It is worth mentioning that the portable dust removal device 10 provided by the present invention, which can be used for both charging and suction, can also be equipped with some auxiliary functions on the device body according to actual needs, such as temperature control system, heat dissipation system, early warning and forecasting system and automatic control system. Any improvement to the auxiliary functions of the portable dust removal device 10 is within the protection scope of this application.

[0154] The present invention also provides another portable dust removal device 20, see [link to relevant documentation]. Figure 10 and Figure 11 The portable dust removal device 20 includes, in addition to the aforementioned housing 100, air pressure assembly 200, cleaning accessory 300, and nozzle accessory 400, a filter assembly 700, a drive source 600, a power supply assembly 910, and a cover assembly 920. The cleaning accessory 300 is located in the cavity 101 and partially extends out of the suction port 102. The cleaning accessory 300 cleans the surface to be cleaned by means of movement. The drive source 600 is located in the cavity 101 and is used to drive the movement of the cleaning accessory 300. The power supply assembly 910 is located in the cavity 101 and provides power to the air pressure assembly 200 and the drive source 600. The cover assembly 920 is located in the cavity 101 and is used to store and protect the cleaning accessory 300.

[0155] In some embodiments, such as Figure 11 As shown, the portable dust removal device 20 of this application achieves miniaturization of the outer shell 100 and orderly arrangement of internal components through its unique structural design. For example, from the suction port 102 to the air outlet 103 of the cavity 101, a cover assembly 920 with a customized shape and size, cleaning accessories 300, filter assembly 700, drive source 600, air pressure assembly 200, and power supply assembly 910, as well as other components of the portable dust removal device 20 (e.g., touch panel, air guide cover, etc.) can be combined to form a complete portable dust removal device 20. Specifically, by connecting the cover assembly 920, cleaning accessories 300, filter assembly 700, drive source 600, air pressure assembly 200, and power supply assembly 910 in series within the cavity 101, a compact and efficient cleaning system is formed, enabling powerful cleaning performance without occupying excessive space.

[0156] In some embodiments, each component of the portable dust removal device 20 is detachably connected to the housing 100 or other components, making the assembly and subsequent disassembly of each component more convenient and efficient.

[0157] In some embodiments, one end of the cleaning accessory 300 is a mounting end, which is used to mount on the output shaft of the drive source 600 to realize power transmission between the cleaning accessory 300 and the drive source 600; the other end is a cleaning end, which is used to clean the surface to be cleaned under the drive of the drive source 600.

[0158] Optionally, the surface to be cleaned can be a flat surface or an uneven surface, a hard surface or a soft surface, etc. Furthermore, users can replace the corresponding cleaning accessory 300 to clean different types of surfaces, so as to achieve effective cleaning of the surface. Therefore, the cleaning accessory 300 is ingeniously designed and can flexibly meet the cleaning needs of different surfaces and environments.

[0159] In one embodiment, in order to ensure the strength of the mounting end of the cleaning accessory 300 and to prevent the excessively long mounting end and output shaft from deforming or being damaged under stress, the cleaning accessory 300 can be configured to partially extend out of the cavity 101 from the suction port 102. However, in other embodiments, the mounting end may not extend into the suction port 102, that is, the cleaning accessory 300 may be configured to extend entirely out of the suction port 102. In this case, part of the output shaft extends out of the suction port 102, and the mounting end and the output shaft are fixedly assembled.

[0160] In some embodiments, the drive source 600 is installed inside the cavity 101 and positioned after the cleaning accessory 300, responsible for driving the movement of the cleaning accessory 300 to achieve the cleaning capability of the device. The drive source 600 is a detachable and replaceable drive motor, which may be a rotary motor, a vibration motor, or an ultrasonic generator, etc.

[0161] For example, the drive source 600 can be a rotary motor, which drives the cleaning accessory by rotation, so that the cleaning accessory can rotate and clean the surface to be cleaned. The rotary motor can be used to clean oil stains or fingerprints on the surface. It can provide smooth rotational power to the cleaning accessory 300, so that the cleaning accessory 300 can effectively contact the surface to be cleaned, thereby efficiently removing the attached stains without damaging the surface.

[0162] For example, the drive source 600 can be a vibration motor, which drives the cleaning accessories by vibration, so that the cleaning accessories can vibrate and clean the surface to be cleaned. The vibration motor can be used to clean dust adhering to the surface. The fine vibration it generates can effectively loosen and shake off the dust adhering to the surface, enhancing the cleaning effect, especially when dealing with fabrics or uneven surfaces.

[0163] For certain scenarios, such as deep cleaning of stubborn stains or fine particles, the drive source 600 can be an ultrasonic generator, which uses high-frequency sound waves to achieve a deep cleaning effect on the surface.

[0164] The 600 drive source offers a variety of options, including rotary motors, vibrating motors, and ultrasonic generators, enabling it to provide optimal solutions for different cleaning needs, thus meeting the cleaning requirements of homes, industries, and special environments.

[0165] In some embodiments, the air pressure assembly 200 is located inside the cavity 101 and is positioned after the power supply assembly 910. It is used to generate air pressure inside the cavity 101, which draws debris from the surface to be cleaned into the cavity 101 through the suction port. This function is effectively implemented in a small space, enhancing the device's suction capability.

[0166] The wind pressure assembly 200 may include a motor and a fan blade. The motor is fixedly installed in the housing 100 and housed in the cavity 101. The fan blade is sleeved on the motor's power shaft. 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.

[0167] In some embodiments, the power supply component 910 is sequentially disposed in the cavity and located between the air pressure component 940 and the drive source 600. Its function is to effectively filter the garbage entering the cavity 101, ensure the cleaning effect, and prevent the garbage from flowing back into the environment, thereby improving the safety of the user.

[0168] The power supply component 910 can be made of a microporous ceramic filter to filter larger dust particles; or a metal mesh, which is low in cost and has a good filtration effect; or a sponge filter layer to filter out larger substances in the air; or a HEPA filter layer to filter out smaller particles, and the filtration effect is better when used in combination.

[0169] In a specific implementation scenario, when the portable dust removal device 20 is working, the drive source 600 first drives the cleaning accessory 300 to move, so that the cleaning accessory 300 sweeps off the garbage on the surface to be cleaned; then the wind pressure assembly 200 drives the fan blades to rotate, thereby generating wind pressure in the cavity 101, so as to suck the garbage on the surface to be cleaned into the cavity 101 through the suction port 102; then the filter assembly 700 filters the air carrying garbage in the suction cavity 101, so as to discharge the filtered clean air from the air outlet; finally, the cleaning accessory 300 is stored through the cover assembly 920.

[0170] The cover assembly 920 not only stores and protects the cleaning accessories 300, but can also be designed as a wired / wireless charging dock or charging case. This allows the portable dust removal device 20 to automatically charge after the cleaning accessories 300 are placed inside the cover assembly 920, eliminating the need for a charging port on the main unit or for the user to charge the battery separately. Furthermore, the assembly can be equipped with other multi-functional designs. For example, cleaning materials can be placed inside the cover, allowing the brush head to be cleaned when it is returned to the cover, avoiding the hassle of separate tool cleaning and greatly improving the convenience and maintenance efficiency of the cleaning device.

[0171] As a specific implementation, the portable dust removal device 20 includes at least a handheld dust removal pen for wireless handheld use and an automatic dust removal device for automatic opening and closing and dust collection.

[0172] This handheld dust removal pen features a wireless design, making it lightweight and portable, ideal for handheld use. Its ergonomic design allows for extended use during cleaning, reducing fatigue. This dust removal pen is suitable for cleaning dust and dirt from desktops, keyboards, windowsills, and other confined areas. The wireless design allows for easy movement, enhancing the convenience and flexibility of operation.

[0173] Among them, the automatic dust collector features intelligent on / off functions, allowing it to autonomously clean preset fixed areas according to a pre-set operating mode. During operation, it can be remotely controlled by the user or automatically turned on or off based on environmental conditions, thus improving user convenience. Furthermore, the dust collector can connect to other smart devices to achieve remote control and timed cleaning functions.

[0174] Since the portable dust removal device 20 of this application embodiment includes the aforementioned portable dust removal device 10 that can be used for both filling and suction, the portable dust removal device 20 of this application embodiment has the beneficial effects of the aforementioned wind pressure component 200, which will not be described in detail here. Furthermore, this embodiment of the invention includes a cleaning accessory 300, which is disposed through the fixing part of the mounting component 500. The wind pressure component 200 and the filter sponge are fixed in a ring-like manner within the fixing part, which better adapts to the structure of the cavity 101 and provides a better shielding effect.

[0175] The technical advantages of the above solution are as follows: This device not only avoids the bulkiness and inconvenience of traditional cleaning tools, but also provides a portable, flexible, and efficient solution, meeting the expectations of modern users for portable cleaning equipment. Users can easily carry this device to every corner of their daily lives for cleaning at any time, improving their quality of life. Specifically, on the one hand, by using a handheld mini shell to house cleaning accessories, a drive source, a wind pressure component, and a filter module, unlike existing technologies, the device significantly reduces its physical size, achieving miniaturization and thus improving its portability and operability. On the other hand, by employing a rational structural design for the suction port and air outlet, this solution integrates cleaning accessories and / or air nozzles into the dust removal device. This allows the device to not only vacuum and clean surfaces but also perform inflation operations simultaneously, with simple and convenient operation, thereby improving the efficiency of the dust removal device and meeting multiple cleaning needs.

[0176] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
