[0002] A dust collector is a cleaning device widely used in human life and industrial production. The working principle of the dust collector is to use a driving motor to drive a blade to rotate at high speed, generate a powerful airflow in a sealed shell, form a negative pressure, and thus attract air and dust and pollutants carried by the air into the dust collector.

[0003] At present, the traditional dust collector mainly includes a dust collector host and a dust suction nozzle. The front end of the dust collector host is provided with an air suction port, and the rear end is provided with an air exhaust port. The rear end of the dust suction nozzle is inserted into the air suction port, and the outer wall of the rear end of the dust suction nozzle is tightly sealed with the inner wall of the air suction port. The front end of the dust suction nozzle forms a dust suction end. When the dust collector host works, a negative pressure can be generated in the dust suction nozzle, so that dust can be sucked away by the dust suction nozzle and stored in a dust box located inside the dust collector host.

[0004] However, the above-mentioned dust collector can only realize the function of dust collection, thereby having the disadvantage of single function. Therefore, under the background of the increasing demand for portable and multifunctional dust collectors in the market, the use effect of the traditional dust collector is not convenient enough.

These terms are only used to distinguish one element from another, and are not used to describe a specific order. For example, the first shell can be referred to as the second shell, and the second shell can also be referred to as the first shell, only the scope of the two is different, without departing from the scope of the present application, the first shell and the second shell are both shell accessories configured in the portable dust removal equipment, only the two are not shell accessories of the same structure design.

[0050] To explain the technical content, technical steps, purposes and effects of the present application in detail, the following will be described in detail in conjunction with the embodiments and the accompanying drawings.

[0051] The conventional dust removal equipment usually only has the dust collection function, and in actual use, the user often needs additional equipment to perform the inflation operation, which makes the user need to carry multiple tools when handling different cleaning tasks, increasing the inconvenience of use. The existing portable dust collector has limitations in size and function, and cannot meet the requirements of modern consumers for multifunctionality and portability. Therefore, it is necessary to develop a new portable dust removal equipment to achieve more efficient cleaning and inflation goals.

[0052] The utility model provides a portable dust removal equipment 10 of charge and inhale dual purpose, please refer to Figures 1 to 4 The dust removal equipment 10 includes a shell 100, a wind pressure assembly 200, a cleaning accessory 300 and / or an air nozzle accessory 400. Among them, the shell 100 is a hand-held mini shell, which has a cavity 101 inside the shell 100, and a dust suction port 102 and an air outlet 103 are formed on the shell 100 and communicated with the cavity 101. The wind pressure assembly 200 is arranged in the cavity 101 and used to generate wind pressure in the cavity 101. The cleaning accessory 300 is arranged in the cavity 101 and at least partially extends out of the dust suction port 102, which is used to clean the surface to be cleaned close to the dust suction port 102, and the dust particles on the surface to be cleaned are sucked into the cavity 101 from the dust suction port 102 by the airflow generated by the wind pressure, so as to perform the dust removal operation. The air nozzle accessory 400 is arranged at the air outlet 103 and connected to the inflation device 500, which is used to inject the airflow generated by the wind pressure into the inflation device 500 from the air outlet 103 to perform the inflation operation.

[0053] For the shell 100, please continue to refer to 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 the embodiments of the present application, the axis of the shell 100 is the central axis direction of the cylindrical shell 100, and the airflow direction of the portable dust removal equipment 10 during operation is parallel to the axis direction. In other embodiments, when the shell 100 is not cylindrical, the axis of the shell 100 is the extension direction of the main structure, and the airflow direction is parallel to the axis direction.

[0060] In some embodiments, as shown in Figure 2 , the portable dust removal equipment 10 of the present application realizes the miniaturization of the shell 100 and the orderly arrangement of the internal components through its unique structural design. For example, from the dust suction port 102 of the cavity 101 to the air outlet 103, the cleaning accessory 300, the driving source 600, the mounting assembly 800, the air pressure assembly 200, the filter assembly 700 and other components (such as battery, wind deflector, etc.) of the portable dust removal equipment 10 can be combined together in sequence with shapes and sizes adapted to the cleaning accessory 300, thereby forming a complete portable dust removal equipment 10. Among them, the cleaning accessory 300, the driving source 600, the mounting assembly 800, the air pressure assembly 200 and the filter assembly 700 are connected in sequence in the cavity 101 to form a compact and efficient cleaning system, so that powerful cleaning performance can be achieved without occupying too much space.

[0061] In some embodiments, each component in the portable dust removal equipment 10 is detachably connected to the shell 100 or other components, so that the assembly and subsequent disassembly of each component are more convenient and efficient.

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

[0063] In some embodiments, the air pressure assembly 200 is located in the cavity 101 and is arranged after the filter assembly 700, which is used to generate air pressure in the cavity 101. Its function is to suck the garbage on the surface to be cleaned into the cavity 101 through the dust suction port, which effectively implements the function in the mini space and enhances the dust removal capacity of the equipment.

[0064] The wind pressure assembly 200 can include a wind pressure motor 210 and a centrifugal fan blade 220. The wind pressure motor 210 is fixedly installed on the shell 100 and accommodated in the cavity 101. The centrifugal fan blade 220 is sleeved on a power shaft 211 of the wind pressure motor 210. The wind pressure motor 210 can drive the centrifugal fan blade 220 to rotate, so that the wind pressure is generated in the cavity 101, and the gas flow is generated 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] The cleaning accessory 300 has one end as a mounting end 310 for mounting on the output shaft 610 of the driving source 600 to realize power transmission between the cleaning accessory 300 and the driving source 600, and the other end as a cleaning end 320 for cleaning the surface to be cleaned under the driving of the driving source 600. Figure 3

[0066] In some embodiments, the mounting end 310 is provided with a mounting shaft 311 with a hexagonal cross section on the side away from the cleaning end 320. The output shaft 610 of the corresponding driving source 600 is also provided with a hexagonal mounting hole (not shown in the figure). The mounting shaft 311 is mounted on the output shaft 610 in a plug-in manner to realize power transmission between the cleaning accessory 300 and the driving source 600, so as to ensure that the cleaning accessory 300 can stably operate while bearing the dynamic force.

[0067] In some embodiments, the mounting shaft 311 can be made of a magnetic material, and the end of the output shaft 610 of the driving source 600 is also provided with a magnetic material, and the magnetism of the two is opposite. The cleaning accessory 300 is installed by plug-in and also by magnetic attraction to realize detachable installation. Compared with the plug-in installation, the magnetic assembly is more labor-saving and easy to assemble, and has a sense of assembly in place.

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

[0069] ​The installation end 310 is designed in a solid cylindrical ring structure, which makes the installation end 310 have good stability and carrying capacity, can withstand kinetic energy in the cleaning process, and is convenient for connection with the dust collection system. The diameter of the base body 210 is designed to be smaller than the diameter of the dust collection port 102, so that the installation end 310 can be effectively combined with the dust collection port 102, ensuring smooth airflow path and providing favorable conditions for subsequent dust collection.

[0070] Optionally, the surface to be cleaned can be a flat surface or a concave-convex surface, and can also be a hard surface or a soft surface, etc. For different types of surfaces to be cleaned, the user can also replace the corresponding matching cleaning accessory 300 for cleaning to effectively clean the surface to be cleaned. Therefore, the cleaning accessory 300 is designed to be exquisite and can flexibly cope with the cleaning needs of different surfaces and environments.

[0071] In some embodiments, in order to ensure the strength of the installation end 310 of the cleaning accessory 300 and prevent the excessively long installation end 310 and the output shaft 610 from being deformed or damaged under stress, the cleaning accessory 300 can be partially arranged to extend out of the dust collection port 102 into the cavity 101, but in other embodiments, the installation end 310 can also be arranged without extending into the dust collection port 102, that is, the cleaning accessory 300 is arranged to extend out of the dust collection port 102 in its entirety, and in this case, the output shaft 610 partially extends out of the dust collection port 102, and the installation end 310 and the output shaft 610 are fixedly assembled.

[0072] In some embodiments, as shown in Figure 2 The driving source 600 is installed in the cavity 101 and arranged behind the cleaning accessory 300, which is responsible for driving the movement of the cleaning accessory 300 to realize the cleaning capability of the device. The driving source 600 is a detachable driving motor, and the type of the driving motor includes a rotating motor, a vibrating motor, or an ultrasonic wave generating device, etc.

[0073] For example, the driving source 600 can be a rotating motor, which is used to drive the cleaning accessory 300 in a rotating manner to make the cleaning accessory 300 rotate on the surface to be cleaned. The rotating motor can be used in the scene of cleaning oil stains or fingerprint marks on the surface, which can provide stable rotating power for the cleaning accessory 300, so that the cleaning accessory 300 effectively contacts the cleaning surface, thereby efficiently removing the attached stains without damaging the surface.

[0074] For example, the driving source 600 can be a vibration motor, which is used to drive the cleaning accessory 300 by means of vibration to make the cleaning accessory 300 vibrate on the surface to be cleaned. The vibration motor can be used in the scene of cleaning dust adhesion on the surface, and the fine vibration generated by the vibration motor can effectively loosen and shake off the dust adhered to the surface, thereby enhancing the cleaning effect, especially when dealing with fabrics or uneven surfaces.

[0075] For some specific scenarios, such as stubborn stains or deep cleaning of fine particles, the driving source 600 can be an ultrasonic device, so as to achieve the deep cleaning effect of the cleaning surface by means of the high-frequency sound waves generated by the ultrasonic device.

[0076] The use of the rotating motor, the vibration motor and the ultrasonic device provides the driving source 600 with the optimal solution under different cleaning requirements, thereby meeting the cleaning requirements in the family, industry and special environment.

[0077] In some embodiments, as shown in Figure 2 The portable dust removal device 10 further comprises a filtering assembly 700 arranged in the cavity 101, which is used to filter the air flow sucked into the cavity 101 from the dust suction port 102.

[0078] Specifically, the filtering assembly 700 is arranged in the cavity in sequence and located between the air pressure assembly 200 and the driving source 600. The filtering assembly 700 is used to effectively filter the garbage entering the cavity 101, so as to ensure the cleaning effect, prevent the garbage from flowing back to the environment, and improve the safety of the user.

[0079] The filtering assembly 700 can be a microporous ceramic filter screen for filtering larger particles of dust, and / or a metal screen with low cost and good filtering effect, and / or a sponge filter layer for filtering larger substances in the air, and / or a hepa filter layer for filtering smaller particles, and the filtering effect is better when the filtering layers are used in combination.

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

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

[0082] Specifically, as shown in Figure 4 The types of valve assemblies 400 can include the following: ① flange valve, which can be used for inflating tires, usually made of metal material, durable and not easy to leak. ② plastic valve, commonly used for balloons and small inflatable toys, light and easy to use. ③ universal valve, suitable for a variety of products, usually with different adapters to accommodate different inflation needs.

[0083] In some embodiments, the design of the valve assembly 400 can have various shapes and sizes to adapt to different models and types of air pumps and different inflation objects such as tires, balloons, lifeboats, etc. And the valve assembly 400 can be made of wear-resistant materials (such as plastic or metal) to ensure its durability and elasticity under high pressure, prevent breakage or deformation during use. And its good sealing design can effectively prevent gas leakage, improve inflation efficiency and reduce air waste.

[0084] In some embodiments, the valve assembly 400 specifically includes the following application functions: ① inflation function, for delivering gas (i.e. airflow) from the air outlet 103 to the device to be inflated 500 for rapid inflation. ② Deflation function, the valve assembly 400 with deflation function can adjust the gas outflow, facilitate the deflation of the target object. ③ Connection function, the valve assembly 400 can safely connect the air outlet 103 and the device to be inflated 500 to ensure that it will not fall off during inflation. ④ Control airflow function, the valve assembly 400 is designed with a valve or switch that can be used to control the inflation speed and air flow. ⑤ Adapt to different air pressure function, the valve assembly 400 can adapt to different air pressure needs, so as to be suitable for a variety of inflation scenarios.

[0085] In a specific implementation scenario, the portable dust removal device 10 of the present application is provided with a cleaning accessory 300 at the dust suction port 102 of the shell 100, which cleans the surface to be cleaned near the dust suction port by the cleaning accessory 300, and the airflow generated by the air pressure of the air pressure assembly 200 sucks the dust particles on the surface to be cleaned into the cavity 101 of the shell 100 from the dust suction port 102 to perform the dust removal operation; or, the air nozzle accessory 400 is installed at the air outlet 103 of the shell 100, which is connected to the device to be inflated 500 through the air nozzle accessory 400, so that the airflow generated by the air pressure of the air pressure assembly 200 is injected into the device to be inflated 500 to perform the inflation operation.

[0086] In an embodiment, the portable dust removal device 10 of the present application at least includes a handheld dust removal pen for wireless use, and an air charging and suction pump for automatic use.

[0087] In some embodiments, the handheld dust removal pen adopts a wireless design, is light and portable, and is suitable for handheld use. The design conforms to ergonomics, is convenient for users to hold for a long time during use, and reduces fatigue. The dust removal pen is suitable for cleaning and sucking dust and dirt on desktops, keyboards, window sills and other narrow areas, and can also be used for inflation operations such as tires, balloons, lifeboats, etc. The user can move at will through the wireless design, enhancing the convenience and flexibility of operation.

[0088] In some embodiments, the automatic air charging and suction pump has an intelligent opening and closing function, and can automatically clean or inflate a predetermined fixed area according to a predetermined working mode. The user can remotely control it or automatically open or close it according to the environmental conditions during operation, thereby improving the user's convenience. At the same time, the air charging and suction pump can be connected with other smart devices of the user to realize remote control and timing cleaning functions.

[0089] The technical effect of the above scheme is that, on the one hand, the wind pressure assembly, cleaning accessory, etc. are accommodated in the cavity by a handheld mini shell, which greatly reduces the physical volume of the dust removal device, making the device easy to carry and suitable for cleaning needs in various occasions, thereby improving the portability and operability of the dust removal device; on the other hand, by means of reasonable structural design of the dust suction port and the air outlet structure, the cleaning accessory and / or the air nozzle accessory are integrated into the dust removal device, so that the dust removal device can not only clean the surface, but also perform inflation operation with the same device, and the operation is simple and convenient, thereby improving the use efficiency of the dust removal device and meeting multiple cleaning needs.

[0090] Those skilled in the art can understand that, Figures 1 to 4The portable dust removal equipment shown in the above figures is only a block diagram of part of the structure related to the scheme of the present application, and does not constitute a limitation on the dust removal equipment to which the scheme of the present application is applied. The specific air pressure assembly can include more or fewer components than those shown in the figures, or combine certain components, or have a different arrangement of components.

[0091] Please continue to refer to Figure 1 and Figure 2 For the housing 100 in the above embodiment, the housing 100 further comprises a detachable first shell 110 and a second shell 120, which together enclose a cavity 101. Specifically, the part of the cavity 101 inside the first shell 110 is divided into a dust cavity 101a, and the part of the cavity 101 inside the second shell 120 is divided into a mounting cavity 101b. Specifically, the filter assembly 700 is installed in the first shell 110 and divides the cavity 101 into the mounting cavity 101b and the dust cavity 101a. The air pressure assembly 200 is installed in the mounting cavity 101b, the dust suction port 102 is arranged at one end of the first shell 110 away from the second shell 120, and the air outlet 103 is arranged at one end of the second shell 120 away from the first shell 110, or the air outlet 103 is arranged at one side of the second shell 120 close to the air pressure assembly 200.

[0092] In an embodiment, as shown in Figure 1 , the structure of the housing 100 comprises a detachable first shell 110 and a second shell 120, which together enclose a cavity 101. This structure design aims to improve the maintainability and operational convenience of the equipment, and facilitate the user to clean and maintain them separately after disassembling them.

[0093] Further, the filter assembly 700 is installed in the first shell 110 inside the cavity 101, which divides the cavity 101 into two areas: the mounting cavity 101b and the dust cavity 101a. This design makes the flow of air inside the equipment more orderly and effectively separates impurities from clean air.

[0094] Further, the dust suction port 102 is arranged at one end of the first shell 110 away from the second shell 120 to ensure that dirt and garbage can be quickly sucked in during the cleaning process. At the same time, the clean airflow after passing through the filter assembly 700 will form in the mounting cavity 101b and finally be discharged through the air outlet 103, ensuring that the released air is clean and pollution-free.

[0095] The separation effect of the filtering assembly 700 realizes the optimization of the airflow direction, so that the garbage on the surface to be cleaned will quickly enter the dust chamber 101a after being sucked into the cavity 101 through the dust suction port 102. The design can effectively capture and store impurities, greatly reducing the risk of impurities flowing back to the environment with the airflow. At the same time, the clean airflow filtered can smoothly pass through the installation cavity 101b and be discharged to the air outlet, thereby improving the overall cleaning efficiency.

[0096] In some embodiments, the first shell 110 and the second shell 120 are both elongated cylindrical shell structures, each with a diameter of 2.5 centimeters, and the first shell 110 and the second shell 120 are fixed by screwing. In the assembled state, the length of the shell 100 is about 15 centimeters. The dust chamber 101a and the dust suction port 102 in the shell are coaxially arranged and communicate with each other, and the installation cavity 101b and the dust chamber 101a are cylindrical in cross-sectional shape, and the cross-sectional shape of the dust suction port 102 is circular.

[0097] The cross sections of the installation cavity 101b, the dust chamber 101a, and the dust suction port 102 are circular to ensure uniform suction and consistent appearance and thickness of the shell 100. However, the specific shapes of the installation cavity 101b, the dust chamber 101a, and the dust suction port 102 can also be other styles, such as the cross-sectional shapes of the installation cavity 101b and the dust chamber 101a can 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 chamber 101a. In other embodiments, the first shell 110 and the second shell 120 can be fixed by clamping or inserting, or can be opened and closed by a shaft connection and locking structure, which is not limited here.

[0098] In addition, in the embodiments of the present application, the airflow direction refers to the direction of the gas flowing in the cavity 101. The airflow direction is generally the axis direction of the first shell 110 and the second shell 120, which may slightly deviate in the radial direction of the cavity 101 due to the blocking effect of the air guide structure and the internal parts at some positions of the cavity 101. The airflow direction described in the limiting direction refers to the axis direction of the first shell 110 and the second shell 120, and the outer contour of the first shell 110 and the second shell 120 is cylindrical, and the axis is the center axis of the corresponding cylinder.

[0099] The technical effect of the above scheme is that by designing the cavity of the shell into an installation cavity and a dust cavity, more efficient garbage separation and airflow optimization are achieved. After the cleaning airflow flows through the filter assembly, impurities can be effectively isolated, and the purified air is safely discharged to the air pressure assembly 200. In addition, the shell structure improves the use stability and cleaning performance of the equipment, optimizes the cleaning effect, and greatly improves 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 an installation cavity 101b. The dust suction port 102 is communicated with the dust cavity 101a, and the air outlet 103 is communicated with the installation cavity 101b. The dust cavity 101a and the installation cavity 101b are communicated with each other through a vortex flow channel. The impeller of the centrifugal blade 220 is installed in the installation cavity 101b. Specifically, under the drive of the motor, the centrifugal blade 220 and the driving source 600 rotate synchronously, at this time, the centrifugal blade 220 draws external gas through the dust suction port 102 into the dust cavity 101a, and then draws the gas in the dust cavity 101a into the installation cavity 101b through the vortex flow channel, and discharges it from the air outlet 103.

[0101] The embodiment can accelerate the flow of gas in the installation cavity 101b by providing the installation cavity 101b communicated with the dust cavity 101a and adding the driving source 600 rotating synchronously with the centrifugal blade 220 inside the installation cavity 101b, so as to increase the pressure of the gas discharged from the air outlet 103. In addition, the greater the flow rate of the gas in the installation cavity 101b, the smaller the gas pressure, and the more gas in the dust cavity 101a will flow into the installation cavity 101b due to the pressure difference. That is to say, the gas pressure in the dust cavity 101a will decrease faster, and the speed of the gas drawn from the outside will also increase, further increasing the pressure of the gas discharged from the air outlet 103 and improving the air charging efficiency.

[0102] It is worth mentioning that the dust cavity 101a and the installation cavity 101b are arranged correspondingly before and after, and as a preferred, the dust suction port 102 is arranged on the front end face and communicated with the dust cavity 101a corresponding to the front end face. The air outlet 103 is arranged on the side wall of the shell 100 and adjacent to the rear end face, and is communicated with the installation cavity 101b corresponding to the rear end face.

[0103] In the embodiment, the vortex flow channel has a first flow channel port in the dust cavity 101a and a second flow channel port in the installation cavity 101b. The first flow channel port is arranged on one side of the dust cavity 101a and communicated with the dust cavity 101a. Correspondingly, the second flow channel port is arranged at the upper end of the installation cavity 101b and communicated with the installation cavity 101b.

[0104] Since the driving source 600 in the dust cavity 101a drives the gas in the dust cavity 101a to rotate during rotation, based on the influence of centrifugal force during rotation, the first flow channel port communicated with the dust cavity 101a is arranged at one side of the dust cavity 101a, so that the gas in the dust cavity 101a can be quickly pumped to the mounting cavity 101b through the vortex flow channel. The second flow channel port communicated with the mounting cavity 101b is arranged at the front end of the mounting cavity 101b, which is more conducive to the secondary acceleration of the gas flow rate in the mounting cavity 101b by the centrifugal blade 220, thereby increasing the pressure of the gas discharged from the air outlet 103 and improving the air charging efficiency.

[0105] Preferably, the dust cavity 101a is provided with a barrier portion, one end of the barrier portion is connected to the shell 100, and a gap is formed between the other end of the barrier portion and the shell 100. The barrier portion and the dust cavity 101a form a rotating station therebetween, which is adapted to the driving source 600 for rotation of the driving source 600. At this time, the area of the dust cavity 101a other than the rotating station forms the first flow channel port, and the gap allows the rotating station and the first flow channel port to communicate with each other.

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

[0107] Further, in the embodiment, the barrier portion is arranged to separate the dust cavity 101a into the rotating station and the first flow channel port, so that when the driving source 600 drives the gas in the dust cavity 101a to rotate, no gas that has not been accelerated by rotation directly escapes into the first flow channel port, which can effectively ensure the air pumping effect. Moreover, the profile of the rotating station can be adapted to the driving source 600, so that the driving source 600 can drive all the gas in the rotating station to rotate in the maximum range, thereby improving the efficiency of pumping external gas.

[0108] On this basis, the barrier portion is provided with a first flow guide slope surface at one end corresponding to the gap, and a second flow guide slope surface is arranged at the top end of the dust cavity 101a and at a position corresponding to the first flow channel port. The first flow guide slope surface and the second flow guide slope surface are used together to guide the gas in the dust cavity 101a into the vortex flow channel through the first flow channel port.

[0109] In the embodiment, the first flow guide slope surface and the second flow guide slope surface are arranged to ensure that the gas flow rate in the dust cavity 101a is not affected by collision when the gas is pumped to the mounting cavity 101b. Moreover, the first flow guide slope surface and the second flow guide slope surface are arranged to smoothly guide more gas into the vortex flow channel, thereby improving the air charging efficiency.

[0110] In actual production, the second flow guide slope surface can be a hollow block structure, which can be preferably fixed on the upper cover, and of course can be fixed on the side wall of the dust cavity 101a, and the specific structure and setting position can be flexibly changed according to the actual situation, which is not limited herein. The surface for guiding flow of the first flow guide slope surface and the second flow guide slope surface can be an arc surface or an inclined surface, which is within the protection scope of the patent.

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

[0112] When the gas is pumped from the dust cavity 101a to the installation cavity 101b, the vortex flow channel can ensure that the pumped gas is all concentrated in the vortex flow channel and pumped to the installation cavity 101b along the trajectory, and gas diffusion does not occur. Specifically, in order to ensure that the flow rate of the gas is not affected during the process of being pumped from the dust cavity 101a to the installation cavity 101b, the flow guide ring 104 can be bent and extended from the inner wall of the shell 100 towards the middle position of the shell 100 in the rotation direction of the driving source 600, so as to guide the gas of the first flow channel port to the second flow channel port.

[0113] In the embodiment, the driving source 600 rotates counterclockwise, at this time, the flow guide ring 104 is bent and extended from the inner wall of the shell 100 towards the middle position of the shell 100 in the counterclockwise direction. In actual production, the driving source 600 can also rotate clockwise, at this time, the flow guide ring 104 is bent and extended from the inner wall of the shell 100 towards the middle position of the shell 100 in the clockwise direction, which is not limited herein.

[0114] In addition, the bent and extended arrangement of the flow guide ring 104 can further weaken the collision between the gas and the side wall during the pumping process, so as to ensure that the flow rate of the gas is not affected. The specific structure of the flow guide ring 104 in the embodiment can not be limited, and can be flexibly set according to the actual use requirement, which is within the protection scope of the patent.

[0115] In some embodiments, as shown in Figure 2 The portable dust removal device 10 further includes a mounting assembly 800 fixed in the cavity 101, and the mounting assembly 800 is a cylindrical structure for fixing the wind pressure assembly 200 and guiding the airflow to the air outlet 103 when the airflow flows through the wind pressure assembly 200.

[0116] Specifically, the mounting assembly 800 is fixed in the cavity 101, and the mounting assembly 800 is a cylindrical structure for covering and fixing the wind pressure motor 210, and guiding the airflow to the air outlet 103 when the suction airflow flows through the wind pressure motor 210.

[0117] In an embodiment, as shown in Figure 5 The mounting assembly 800 specifically includes a mounting base 810, a mounting cover 820, and a connecting element 830. The connecting element 830 is curved in the axial direction of the shell 100 to guide the airflow through the air pressure assembly 200 to the air outlet 103 when the portable dust removal device 10 is performing the air charging operation.

[0118] In some embodiments, the mounting base 810 is a cylindrical cavity wall structure without a top cover, i.e., the mounting base 810 is provided with a first opening 801 near the dust suction port 102, the first opening 801 is used to put and fix the air pressure motor 210, and the mounting base 810 and the shell 100 are coaxially arranged.

[0119] In an embodiment, as shown in Figure 5 The mounting cover 820 is also a cylindrical structure, which can be inserted with the mounting base 810 to enclose and completely cover the air pressure motor 210, thereby electromagnetically shielding the air pressure motor 210 and ensuring the electrical stability of the air pressure motor 210.

[0120] By enclosing the air pressure motor 210 with the mounting base 810 and the mounting cover 820, the motor is stable and well protected. This structural design effectively resists damage to the motor from the external environment while providing good support.

[0121] In an embodiment, the mounting assembly 800 can also include a mounting cylinder 840 fixed to the inner wall of the cavity 101 for accommodating the air pressure motor 210 and the centrifugal fan blade 220.

[0122] Specifically, as shown in Figure 5 and Figure 6 The mounting cylinder 840 is a circular cylindrical shell structure without a top cover, i.e., the mounting cylinder 840 is provided with a second opening 802 near the dust suction port 102, which can have an accommodation cavity for accommodating the entire air pressure motor 210 and centrifugal fan blade 220 from the second opening 802, and the connecting element 830 is connected to the inner wall of the mounting cylinder 840 at one end and to the mounting base 810 at the other end in the direction perpendicular to the axis of the shell 100 to achieve the installation of the air pressure motor 210 and the centrifugal fan blade 220 in the cavity 101.

[0123] In some embodiments, as shown in Figure 6 The connecting element 830 is a rib structure, which is curved in the axial direction of the shell 100, and one end of the connecting element 830 is connected to the inner wall of the mounting cylinder 840 and the other end is connected to the mounting base 810 to achieve the installation of the air pressure motor 210 on the shell 100.

[0124] The curved structure of the connecting element 830 helps to guide the gas flow to a smoother path, reducing the resistance of the gas flow. This optimized design ensures that the gas flow after passing through the air pressure motor 210 is more efficient, reducing the risk of gas flow convergence and vortex generation, and improving the utilization rate of air pressure.

[0125] In another embodiment, for the mounting assembly 800, in order to simplify the structure of the shell 100 and reduce the production difficulty of the shell 100, the mounting assembly 800 can be a separate component, that is, the air pressure motor 210 and the centrifugal fan blade 220 are installed on the mounting assembly 800 and then installed together in the shell 100, but in some other embodiments, the mounting assembly 800 can also be integrally formed with the shell 100, which is not limited here.

[0126] In some embodiments, the mounting assembly 800 can have a receiving cavity for receiving the entire air pressure motor 210 and centrifugal fan blade 220 from the second opening 802, that is, the second opening 802 of the mounting assembly 800 and the side of the air pressure motor 210 close to the dust suction port 102 in the gas flow direction are connected to each other, and the mounting assembly 800 is arranged around the inner wall of the shell 100 to separate the installation space for the air pressure motor 210 in the cavity 101.

[0127] In an embodiment, the second opening 802 of the mounting assembly 800 and the side of the air pressure motor 210 close to the dust suction port 102 in the gas flow direction are connection areas, which are both hollow cylindrical structures, so that the mounting assembly 800 and the air pressure motor 210 can be connected.

[0128] The mounting assembly 800 and the air pressure motor 210 can be connected.

[0129] In an implementation scenario, by closely combining the air pressure motor 210 and the centrifugal fan blade 220, the structure is simplified and the assembly efficiency is improved. At the same time, the strong air pressure generation makes the air flow more stable, ensuring the maximization of the cleaning effect. During use, the user can complete the cleaning of various surfaces in a short time through the strong air pressure, thereby improving the use satisfaction.

[0130] The technical effect of the above scheme is that through the reasonable structural design of the installation assembly cylinder structure, the installation of the wind pressure motor and other components is more convenient, thereby improving the assembly efficiency of the dust removal equipment, and through the design that the connecting element is curved in the axial direction of the shell, the suction airflow is guided to a more smooth path, thereby reducing the resistance problem caused by the change of airflow direction and improving the smoothness of gas flow.

[0131] In an embodiment, the connecting element 830 in the installation assembly 800 is an arc-shaped airflow vane; wherein the two sides of the airflow vane are respectively fixed to the circumferential surface of the mounting seat 810 and the inner wall of the mounting cylinder 840 in a preset inclined angle, so as to guide the airflow to the air outlet 103 through the preset inclined angle when the portable dust removal equipment 10 is performing the air charging operation.

[0132] Specifically, as shown in Figure 6 , the overall shape of the airflow vane is arc-shaped, that is, a streamline design is formed, which helps the airflow to flow smoothly along the preset path. Therefore, the arc-shaped structure can effectively reduce the vortex generated when the airflow turns, reduce the resistance and energy loss of the airflow.

[0133] Further, the two sides of the airflow vane are respectively fixed to the circumferential surface of the mounting seat 810 and the inner wall of the mounting cylinder 840 according to a preset inclined angle (such as 30°, 45°, 60°, etc.). The design of the inclined angle ensures that the airflow can flow in a specific direction under the guidance of the vane when being sucked in, thereby increasing the contact area of the airflow with the sucked gas and improving the air charging effect.

[0134] Still further, the airflow vane can be stably fixed between the mounting seat 810 and the mounting cylinder 840 by a suitable fixing method (such as screws, adhesion or buckling), so as to ensure that the vane does not displace or fall off during use, thereby ensuring the effectiveness and stability of its function.

[0135] In an embodiment, the outer contours of the mounting seat 810 and the mounting cover 320 are both provided in a cylindrical manner, and a plurality of airflow vanes are arranged in a circumferential array on the circumferential surface of the mounting seat 810 to provide force support for the mounting seat 810.

[0136] Specifically, referring to Figure 7 , the connecting element 830 is curved in the axial direction of the second shell 120, that is, the connecting element 830 is in a circular arc shape, and the number of the connecting element 830 is 11. The 11 connecting elements 830 are respectively arranged around the circumferential outer contour of the mounting seat 810, and each connecting element 830 is arranged in a circular arc shape, which can increase the contact area while guiding the gas, so as to reduce the resistance to the 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, and the two ends of the connecting element 830 are connected to the mounting cylinder 840 and the mounting seat 810, respectively, to fix the mounting seat 810 in the mounting cylinder 840. In other embodiments, the number of connecting elements 830 can also be 2, 3, or 6 or more, and the plurality of connecting elements 830 are arranged around the mounting seat 810, or the number of connecting elements 830 is directly set to one while ensuring the mounting strength of the mounting seat 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 seat 810, and the mounting cylinder 840 are arranged in a cylindrical manner to optimize the space and keep the distance between the mounting cylinder 840 and the inner wall of the second shell 120 consistent, avoiding uneven wind pressure and causing resistance. In other embodiments, the wind pressure motor 210 can also be fixedly installed on the second shell 120 in other structures to achieve the fixed installation of the wind pressure motor 210.

[0139] In an embodiment, the wind pressure motor 210 is enclosed by the mounting seat 810 and the mounting cover 320, and then the connecting element 830 is connected to the circumferential surface of the mounting seat 810 and the inner wall of the mounting cylinder 840 in the axial direction of the second shell 120 at a predetermined inclination angle. Finally, the mounting cylinder 840 is fitted to the second shell 120 to enclose the entire wind pressure motor 210, thereby achieving the installation of the wind pressure motor 210 in the cavity 101.

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

[0141] In an embodiment, as shown in Figure 8 The air nozzle accessory 400 includes a connecting end 410 and an output end 420. The air nozzle accessory 400 is fixedly connected to the air outlet 103 in a screw buckle structure through the connecting end 410, and is fixedly connected to the air charging device 500 in a screw buckle structure through the output end 420.

[0142] Specifically, as shown in Figure 8 The screw buckle structure includes a screw buckle groove 401 and a screw buckle block 402. The screw buckle groove 401 is arranged on the connecting end 410 and the output end 420 of the air nozzle accessory 400, respectively, and the screw buckle block 402 is arranged on the outer wall or the inner wall of the air outlet 103 and the air charging interface of the air charging 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] The first air nozzle 400a, the second air nozzle 400b and the third air nozzle 400c are sequentially respectively large, medium and small air nozzle heads. The small air nozzle can be used for inflating the portable dust removal equipment 10, such as a swimming ring and a yoga ball. The medium air nozzle can be used for inflating the portable dust removal equipment 10, such as an air cushion. The large air nozzle can be used for inflating the portable dust removal equipment 10, such as an inflatable boat. The air nozzle assembly 400 and the portable dust removal equipment 10 can also meet the high-pressure inflation requirements of tires, balloons and basketballs.

[0148] In other embodiments, in addition to being able to be connected to the air outlet 103 through the screw buckle structure to realize outward air exhaust, when the air nozzle assembly 400 is connected to the air inlet 102 through the screw buckle structure, it can also realize inward air suction.

[0149] Specifically, the screw buckle structure can also include two groups of the same screw buckle groove 401 and the screw buckle block 402. The screw buckle groove 401 is uniformly arranged on the outer wall of the connecting end of the first air nozzle 400a, the second air nozzle 400b and the third air nozzle 400c, respectively. The screw buckle block 402 is uniformly arranged on the inner wall of the air inlet 102 and the air outlet 103 and corresponds to the screw buckle groove 401, respectively. The diameters of the connecting ends of the first air nozzle 400a, the second air nozzle 400b and the third air nozzle 400c are smaller than the diameters of the air inlet 102 and the air outlet 103. The diameters of the air inlet 102 and the air outlet 103 are consistent.

[0162] For another example, the driving source 600 can be a vibration motor, which is used to drive the cleaning accessory in a vibrating manner to clean the surface to be cleaned. The vibration motor can be used in the scene of cleaning dust attachments on the surface, and the fine vibration generated by the vibration motor can effectively loosen and shake off the dust attached to the surface, thereby enhancing the cleaning effect, especially when processing fabrics or uneven surfaces.

[0163] For some specific scenes, such as stubborn stains or deep cleaning of fine particles, the driving source 600 can be an ultrasonic wave generating device, so as to realize the deep cleaning effect of the cleaning surface by the high-frequency sound waves generated by the ultrasonic wave generating device.

[0164] The driving source 600 can provide the optimal solution under different cleaning requirements, so as to meet the cleaning requirements in the family, industry and special environment by using the rotation motor, vibration motor and ultrasonic wave generating device.

[0165] In some embodiments, the air pressure assembly 200 is located in the cavity 101 and arranged behind the power supply assembly 910, for generating air pressure in the cavity 101, which functions to suck the garbage on the surface to be cleaned into the cavity 101 through the dust suction port, and this function is effectively implemented in the mini space, thereby enhancing the dust suction capacity of the device.

[0166] The air pressure assembly 200 can include a motor and a fan blade, the motor is fixedly installed on the shell 100 and accommodated in the cavity 101, and the fan blade is sleeved on the power shaft of the motor, so that the motor can drive the fan blade to rotate, thereby generating air pressure in the cavity 101 and causing gas flow in the cavity 101, so as to suck the garbage on the surface to be cleaned into the cavity 101 through the dust suction port 102.

[0167] In some embodiments, the power supply assembly 910 is arranged in the cavity in sequence and located between the air pressure assembly 940 and the driving source 600, which functions to effectively filter the garbage entering the cavity 101, ensure the cleaning effect, prevent the garbage from flowing back to the environment, and improve the safety of the user.

[0168] The power supply assembly 910 can be made of a microporous ceramic filter screen for filtering larger particles of dust, a metal screen with low cost and good filtering effect, a sponge filter layer for filtering larger substances in the air, and / or a hepa filter layer for filtering smaller particles, and the filtering effect is better when the filter layers are used in combination.

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

[0170] The cover assembly 920 not only serves to store and protect the cleaning accessory 300, but can also be designed as a wired / wireless charging base or charging compartment to automatically charge the portable dust removal device 20 after the cleaning accessory 300 is placed in the cover assembly 920, thereby eliminating the need to install a charging interface on the main machine housing or the need for the user to charge the battery separately. In addition, some related multifunctional designs can also be configured inside the assembly. For example, some cleaning materials are placed in the cover, so that when the brush head is placed back in the cover, the internal cleaning materials can be used to clean the brush head, eliminating the need for the user to clean the tool separately, greatly improving the convenience and maintenance efficiency of the cleaning device.

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