Novel high-efficiency air purification device and sweeping robot

Abstract

This application discloses a novel high-efficiency air purification device and a robotic vacuum cleaner, relating to the field of air filtration technology. The novel high-efficiency air purification device includes a main body, a filter element, and a fan. The main body has an air inlet duct and an air outlet duct. The filter element is installed in the air outlet duct and has a filter chamber inside. The filter element has an air inlet opening that connects to the filter chamber. The air inlet opening connects to the outside of the main body through the air inlet duct, which extends to the bottom and / or side of the main body. The fan is installed in the air outlet duct to allow airflow entering from the air inlet duct to enter the filter chamber through the air inlet opening, then be filtered by the filter element, and finally exit the main body through the air outlet duct. This design can efficiently adsorb hair and lint from the ground and airborne particles without causing lint buildup. Furthermore, because larger particles such as dust and hair adhere to the inside of the filter chamber, even if the fan stops working, the dust and hair will only fall into the filter chamber due to gravity and will not fall outside the filter element.

Description

Technical Field

[0001] This application relates to the field of air filtration technology, and in particular to a novel high-efficiency air purification device and a sweeping robot. Background Technology

[0002] Existing air purifiers primarily employ two configurations for their filters and air inlets: one is a vertically placed filter with side air intake, and the other is a top-bottom or bottom air intake with a horizontally placed filter. Both of these traditional configurations share a common technical flaw: larger particles such as dust and hair in the air are mainly adsorbed onto the outermost surface of the filter. Due to the lack of an effective fixing or guiding structure, these collected hairs or dust particles cannot be firmly adsorbed or restrained on the outer layer of the filter. Therefore, when the air purifier stops operating, the adsorbed hair easily detaches from the bottom or sides of the filter, causing secondary pollution to the surrounding air or ground.

[0003] Meanwhile, the filter elements of existing air purifiers are mostly plate-shaped or cylindrical, and their design also causes hair and dust to mainly accumulate on the outer surface of the filter plate or the outer peripheral wall of the filter cartridge. When replacing or maintaining the filter element, whether removing the entire filter element or tearing off the outermost filter screen or filter cotton, the dust and hair attached to the outer layer of the filter element are very easy to fall off or be re-dispersed into the air due to operational disturbances. This not only affects the cleanliness of the operating environment but also causes great inconvenience to users and may cause secondary pollution.

[0004] Furthermore, the air intake of existing air purifiers is generally a grille or hole with the air inlet on the side. When used in pet-owning environments, it is difficult to absorb clumps of hair that have already formed on the ground (in pet-owning environments, pets shed a lot of hair, which is of a certain length and very light, and easily tangles together). When clumps of hair that have already formed on the ground adhere to the outer shell of the air purifier, or when pet hair adhering to the outer shell of the air purifier tangles together to form clumps, they will accumulate and block the air intake grille or hole, affecting air intake efficiency and making cleaning inconvenient.

[0005] Therefore, a new solution is urgently needed to address the technical problems caused by the design of existing air purifier filters and air intake structures, such as the easy shedding of hair and dust, the potential for secondary pollution during filter replacement, the inconvenience of use, the difficulty in adsorbing pet hair, and the tendency for adsorbed pet hair to clog the air intake grille or holes.

This can avoid affecting the cleanliness of the operating environment and causing inconvenience to users, and it can also avoid the problem of secondary pollution when replacing the filter element.

For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0059] This application discloses a novel high-efficiency air purification device.

[0060] Please see Figures 1 to 4 One embodiment of a novel high-efficiency air purification device provided in this application includes:

[0061] The device consists of the main body 1, the filter element 2, and the fan 3.

[0062] The main body of the device 1 is equipped with an air inlet duct 4 and an air outlet duct 5.

[0063] The filter element 2 is installed in the air outlet duct 5 and has a filter chamber 22 inside; the filter element 2 has an air inlet opening 21 that connects to the filter chamber 22; the air inlet opening 21 connects to the outside of the device body 1 through the air inlet duct 4. The air inlet duct 4 extends at least to the bottom and sides of the device body 1.

[0064] The fan 3 is installed in the air outlet duct 5 to allow the airflow entering from the air inlet duct 4 to enter the filter chamber 22 through the air inlet opening 21, and then be filtered by the filter element 2 before being sent out of the main body 1 of the device through the air outlet duct 5.

[0065] The novel high-efficiency air purification device designed in this application has the following beneficial effects:

[0066] 1. The air inlet duct 4 is a straight ventilation duct design, extending to the bottom and / or side of the main body 1 of the device. Driven by the fan 3, it enables direct air intake from the side and bottom. Compared with the traditional design of grilles and holes at the air inlet, this design can efficiently adsorb hair and clumps on the ground as well as floating hair in the air without causing hair to get stuck.

[0067] 2. The filter element 2 is designed with a filter chamber 22 and an air inlet 21 that connects to the filter chamber 22. External airflow first enters the filter chamber 22 through the air inlet duct 4 and the air inlet 21, and then passes through the filter element 2 and is sent to the outside through the air outlet duct 5. Because larger particles such as dust and hair are attached to the inner wall of the filter chamber 22, even if the fan 3 stops working, the larger particles such as dust and hair will only fall into the filter chamber 22 due to gravity and will not fall outside the filter element 2. This can avoid affecting the cleanliness of the operating environment and causing inconvenience to the user, and can also avoid the problem of secondary pollution when replacing the filter element 2.

[0068] Specifically, due to the unique structural design of filter element 2, larger particles such as dust and hair, after being absorbed, remain on the inner wall of filter element 2. Even if the adsorption is not firm, they will fall due to gravity after the purification device is turned off, still falling into the filter chamber 22 of filter element 2. When replacing filter element 2, because larger particles such as dust and hair are inside filter element 2, compared to traditional air purifiers that require horizontal removal of filter element 2 (which adsorbs dust and hair on the outside) or horizontal tearing of the filter cotton, the re-release of dust and hair carrying bacteria from filter element 2 into the air is significantly reduced. This greatly reduces the adverse effects on the human respiratory system caused by replacing the air filter.

[0069] The above is Embodiment 1 of a novel high-efficiency air purification device provided in this application. The following is Embodiment 2 of a novel high-efficiency air purification device provided in this application. Please refer to the following for details. Figures 1 to 8 .

[0070] Based on the solution of Embodiment 1 above:

[0071] Furthermore, such as Figure 3 as well as Figure 6 As shown, the air inlet 21 is located at the top of the filter element 2. The position of the air inlet 21 can be adjusted according to actual needs, as long as large particles entering through the air inlet 21 can fall into the filter chamber 22 under their own gravity. In addition to the top-facing air inlet 21 design, it can also be a side-sloping upward design. Those skilled in the art can make changes to the design according to actual needs without limitation.

[0072] The upward-facing air inlet 21 is superior to other designs, ensuring that large particles fall into the filter chamber 22 under their own gravity. It also allows for easy top-down loading and unloading. When replacing the filter screen 23 or the filter element 2 itself, the vertical upward removal prevents lateral airflow. Compared to existing technologies where dust and hair accumulate on the outside of the filter screen 23, this design significantly reduces the risk of dust and hair carrying bacteria being released into the air during filter screen 23 replacement, thus minimizing the adverse effects on the respiratory tract.

[0073] Furthermore, such as Figure 2 , Figure 6 as well as Figure 7 As shown, filter element 2 is a filter cartridge structure. Taking the design of the air inlet opening 21 with the top facing upward as an example, the filter cartridge structure can be cylindrical or conical, and there are no specific restrictions.

[0074] The filter element 2 with a cartridge structure has a larger filtration area, enabling more efficient air filtration. Cylindrical cartridge structures are common, with relatively simple manufacturing processes, easier installation and replacement, and more even stress distribution, ensuring stable filtration performance. Conical cartridge structures, based on the characteristics of the air inlet duct 4, allow for more even distribution of incoming airflow within the filter chamber 22, further improving filtration efficiency. Simultaneously, the cartridge structure of the filter element 2 facilitates integration with other components. For example, as further disclosed below: in conjunction with the fan 3, the bottom of the filter element extends into the impeller 32. This design allows airflow to enter the filter chamber 22 more smoothly from the air inlet opening 21, be filtered by the filter element 2, and then exit from the air outlet duct 5. Furthermore, the cartridge structure of the filter element 2 offers advantages in cleaning and maintenance. Compared to some complex-shaped filter elements 2, the cartridge structure is easier to disassemble and clean, effectively extending the service life of the filter element 2 and reducing operating costs. Users can periodically remove the filter element 2 of the filter cartridge structure for cleaning to remove larger particles such as dust and hair that are attached to the inner wall of the filter chamber 22 and the filter screen 23, so that the air purifier can always maintain good filtration performance.

[0075] Filter 2 is made of HEPA (High-Efficiency Particulate Air) material, which is internationally recognized as the best high-efficiency filter material, achieving a filtration efficiency of 99.97% for particles larger than 0.3 microns. Filter 2, made of HEPA material, can more effectively filter out fine particulate matter such as dust, pollen, smoke, bacteria, and viruses in the air, providing users with a cleaner and healthier air environment.

[0076] Meanwhile, the HEPA filter element 2 has excellent air permeability, ensuring efficient filtration without excessively affecting airflow, thus ensuring the air purifier operates at a high efficiency. Furthermore, this type of filter element 2 is highly durable, able to withstand a certain degree of pressure and friction, and is not easily damaged, reducing the inconvenience and cost of frequent filter element 2 replacements.

[0077] Furthermore, such as Figure 3 , Figure 6 as well as Figure 7 As shown, a removable filter screen 23 is installed on the wall of the filter chamber 22. The filter screen 23 is made of nylon material, which allows for individual replacement of the filter screen 23 and extends the service life of the filter element 2.

[0078] Specifically, the nylon filter 23 possesses excellent wear resistance and corrosion resistance, maintaining stable filtration performance over long-term use. The removable nylon filter 23, installed on the wall of the filter chamber 22, allows users to easily remove and replace it when it becomes clogged or damaged after a period of use, without replacing the entire filter element 2. This not only reduces operating costs but also improves the efficiency of the air purifier. Furthermore, the removable nylon filter 23 facilitates cleaning and maintenance. Users can periodically remove the filter 23, rinse it with clean water or use a suitable cleaning agent to remove dust and impurities, restoring its filtration performance. The cleaned filter 23 can then be reinstalled on the wall of the filter chamber 22 for continued use, further extending the lifespan of both the filter 23 and the filter element 2. Simultaneously, this design enhances the flexibility and adaptability of the air purifier. Different operating environments and air quality conditions may place varying filtration requirements on the filter 23; users can select nylon filters 23 with different pore sizes to achieve optimal filtration results. For example, in environments with poor air quality and a lot of dust, a filter 23 with a smaller pore size can be selected to filter out fine particulate matter in the air more effectively; while in environments with relatively good air quality, a filter 23 with a larger pore size can be selected to ensure airflow speed and purification efficiency.

[0079] Regarding the shape design of filter screen 23, it is designed to fit filter element 2. Specifically, it can also be barrel-shaped, but its depth is shallower than that of filter element 2, and it is fitted inside filter element 2.

[0080] Furthermore, such as Figure 3 As shown, the main body 1 of the device includes an inner shell 11 and a top cover 13.

[0081] The inner housing 11 has an installation cavity 51; the top of the inner housing 11 has an installation port that communicates with the installation cavity 51 and is used to insert the filter element 2; the side wall of the inner housing 11 has an air outlet 52; the air outlet 52 and the installation cavity 51 form an air outlet duct 5. The number of air outlets 52 can be one or more, and for example, two outlets can be evenly distributed around the circumference of the installation cavity 51.

[0082] The fan 3 is installed in the mounting cavity 51 and is located below the filter element 2.

[0083] An air inlet cavity 16 is formed between the top cover 13 and the air inlet opening 21; the air inlet duct 4 connects to the air inlet cavity 16. The top cover 13 and the outer shell 12 are detachably connected to facilitate the removal and replacement of the filter element 2. The detachable connection can be a snap-fit, and there are no specific restrictions. The air inlet cavity 16 is set as a transfer cavity, so that the air inlet duct 4 only needs to be connected to the air inlet cavity 16, without having to be directly connected to the air inlet opening 21, thus avoiding the limitation of the design of the air inlet duct 4 due to the shape and size of the air inlet opening 21.

[0084] Furthermore, such as Figure 3 As shown, the design of the fan 3 includes a motor 31 and a fan wheel 32; the fan wheel 32 is mounted on the motor 31; the motor 31 is connected to the fan wheel 32 and is used to drive the fan wheel 32 to rotate; the fan 3 is a common centrifugal fan 3, which will not be described in detail.

[0085] The bottom of the filter element 2 extends into the impeller 32 and has a recessed structure 24 for the top of the power supply 31 to extend into.

[0086] This combination of filter element 2 and fan 3 ensures smoother airflow as it enters filter chamber 22. When motor 31 drives impeller 32 to rotate, it generates strong suction, drawing outside air into air inlet chamber 16 from air inlet duct 4, and then into filter chamber 22 through air inlet opening 21. Because the bottom of filter element 2 extends into impeller 32 and has a concave structure 24 to accommodate the top of motor 31, the airflow generated by the rotation of impeller 32 can directly act on the inside of filter chamber 22, improving the efficiency of air entering filter chamber 22. This design also reduces noise generated by fan 3 during operation. The tight fit between impeller 32 and filter element 2 makes the airflow inside the device more stable, reducing airflow turbulence and collisions, thereby reducing noise generation. Furthermore, the more compact structure helps reduce the overall volume and space occupied.

[0087] Furthermore, such as Figure 3 as well as Figure 8As shown, a support frame 15 is installed in the mounting cavity 51; the shape of the support frame 15 is adapted to the filter element 2, so that the filter element 2 can be placed in it and form a support and fixation for the filter element 2.

[0088] The support frame 15 effectively enhances the stability of the filter element 2 during installation, preventing it from shaking or shifting due to airflow impact or other factors during device operation. This design ensures that the filter element 2 is always in the optimal filtration position, maximizing its filtration effect. Furthermore, when the suction force generated by the fan 3 acts on the filter element 2, the support frame 15 evenly distributes the pressure, preventing excessive localized stress and damage to the filter element 2, thus extending its service life. In addition, the support frame 15 also provides guidance. When placing the filter element 2 into the installation cavity 51, the support frame 15 guides it to the predetermined position accurately, facilitating installation. Simultaneously, it helps maintain the relative positional accuracy between the filter element 2 and other components, ensuring the normal operation of the entire air purification device.

[0089] The material of the supporting space frame 15 can be selected to have a certain strength and corrosion resistance, such as stainless steel, to ensure that it will not rust or deform during long-term use, further improving the reliability and stability of the device. Its installation method can be detachable using fasteners such as screws, and there are no specific restrictions.

[0090] Furthermore, such as Figures 1 to 3 As shown, the main body 1 of the device also includes an outer shell 12; the outer shell 12 is installed outside the inner shell 11; a protective net 121 is provided on the outer shell 12 at the position corresponding to the air outlet 52;

[0091] The protective net 121 effectively prevents foreign objects from entering the air outlet 52, avoiding damage to the internal structure of the device. It also provides a certain level of safety protection, preventing users from accidentally coming into contact with components such as the high-speed rotating fan 3 and getting injured. The mesh size of the protective net 121 can be designed according to actual needs, ensuring that air can pass through smoothly while blocking larger foreign objects.

[0092] For the bottom air intake design, the air intake duct 4 includes a bottom air intake duct 41; the bottom air intake duct 41 is located between the outer shell 12 and the inner shell 11, with one end extending to the bottom of the main body 1 and connecting to the outside of the main body 1, and the other end connecting to the air intake cavity 16; there are multiple bottom air intake ducts 41, which are evenly distributed around the circumference of the inner shell 11. The design of the bottom air intake duct 41 not only solves the problem that the air intake of traditional air purifiers is usually on the side of the body, far from the ground, and cannot adsorb hair or dust close to the ground; more importantly, this air intake method has a better adsorption effect on hair and clumps of fur on the ground, and there is no problem of hair getting stuck.

[0093] Multiple bottom air inlets 41 are evenly distributed around the circumference of the inner shell 11, allowing air to enter the air inlet cavity 16 uniformly from all directions at the bottom of the main body 1. This avoids insufficient or uneven air intake in certain areas, thereby improving the efficiency of air entering the device. Furthermore, this design enables a more stable airflow when entering the air inlet cavity 16, reducing airflow turbulence and further enhancing the overall performance of the air purification device.

[0094] Furthermore, since the bottom air inlet duct 41 is located between the outer shell 12 and the inner shell 11, it can provide a certain degree of sound insulation. When air enters the device through the bottom air inlet duct 41, the structure of the duct can block and buffer the noise generated by the operation of the fan 3, reducing the transmission of noise to the outside. Regarding the design of the bottom air inlet duct 41, it can be formed by the structure between the outer shell 12 and the inner shell 11, or it can be a separate duct structure installed between the outer shell 12 and the inner shell 11; there are no specific limitations.

[0095] Furthermore, such as Figures 2 to 4 As shown, for the side air intake design, the air intake duct 4 also includes a side air intake 42; the side air intake 42 is opened on the side of the top cover 13 and connects to the air intake cavity 16; there are multiple side air intakes 42, which are evenly distributed around the circumference of the top cover 13.

[0096] The design of multiple side air inlets 42 evenly distributed around the circumference of the top cover 13 greatly increases the pathway and area for air to enter the air inlet cavity 16. This allows air to enter simultaneously from multiple sides of the device, further improving the efficiency and uniformity of air intake. In conjunction with the bottom air inlet 41, the side air inlets 42 allow air from different heights and directions to smoothly enter the device, achieving efficient adsorption of airborne hair without causing hair jamming.

[0097] Furthermore, such as Figure 2 as well as Figure 3 As shown, the bottom of the main body 1 of the device is provided with several anti-slip feet 14.

[0098] The anti-slip feet 14 can be made of materials with good anti-slip properties, such as rubber. They are evenly distributed on the bottom of the main body 1 of the device, effectively increasing the friction between the device and the placement surface, preventing the device from sliding or shifting during operation due to factors such as vibration from the fan 3. This not only ensures the stability of the device and avoids damage from accidental sliding, but also reduces friction and collisions between the device and the placement surface, extending the device's service life. Simultaneously, the anti-slip feet 14 also have a certain cushioning effect, reducing the impact of vibrations generated during device operation on the placement surface and reducing noise transmission.

[0099] The anti-slip feet 14 can also be replaced with casters, which greatly enhance the mobility of the air purifier, allowing users to easily change its placement according to their needs. Users can easily move the device from one room to another, ensuring that different spaces can enjoy the air purification effect.

[0100] This application also discloses a robotic vacuum cleaner, including a robot body and a novel high-efficiency air purification device as described above; the novel high-efficiency air purification device is installed on the robot body.

[0101] It is understood that the novel high-efficiency air purification device designed in this application can be combined with a robot vacuum cleaner, that is, the air purification device can be placed on the robot vacuum cleaner. The connection method is not limited, as long as it is stable. Because the bottom air intake design of the air intake duct 4 can efficiently adsorb hair on the ground, and the side air intake of the air intake duct 4 can adsorb floating hair. Of course, depending on the needs, the side air intake can be omitted (that is, the side air intake 42 is not set), that is, only the bottom air intake (bottom air intake duct) is retained.

[0102] The above provides a detailed description of a novel high-efficiency air purification device and a sweeping robot provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
