Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliances, and more particularly to air purification devices. Background Technology
[0002] Most air filtration devices currently have an air inlet at the bottom and an air outlet at the top. During operation, outside air enters the air filtration device through the bottom inlet for purification and then returns to the outside through the top outlet, following a one-way path. The purpose is to ensure that the filtered air is directly blown to the user. However, in environments with a lot of lint or fluff, such as pet hair, willow catkins, or flower fluff, the lint suspended in the air will move along with the airflow path. In other words, lint suspended above the air filtration device that is not promptly driven into the air filtration device will disperse outwards with the air blown out of the outlet.
[0003] However, due to the limited direction of the air inlet and outlet of the air filtration device, it is difficult for the air filtration device to generate enough air driving force to drive the air to form a circulation path. In other words, the lint and dust that are dispersed away from the air filtration device as the air flows out of the outlet are difficult to be collected by the air filtration device.
[0004] For air filtration devices with an air outlet at the bottom and an air inlet at the top, the path for driving airflow is still a single path. Similarly, dust and lint near the air outlet at the bottom of the air filtration device that are not driven into the air filtration device in time will spread outward with the airflow from the air outlet. This, in turn, causes the dust and lint deposited on the ground to float up again.
[0005] In addition, larger lint and dust particles will gradually settle to the ground due to gravity, while fine lint and dust will continue to float in the air. When the latter are collected by air filtration equipment, they are mostly adsorbed onto the filter element. When users replace the filter element, the fine lint and dust adsorbed on the filter element are very easy to detach from the filter element, which greatly affects the user's willingness to replace the filter element. Utility Model Content
[0006] One advantage of this invention is that it provides an air purification device, wherein the air purification device can drive air to form a dual circulation flow path, and the filtered air further drives unfiltered air into the air purification device in order to collect lint and dust suspended in the air.
[0007] Another advantage of this invention is that it provides an air purification device that facilitates the cleaning of fine lint and dust it collects, increasing the user's motivation to clean the air purification device and thus ensuring that the air purification device continuously maintains its purification efficiency.
[0008] Another advantage of this invention is that it provides an air purification device, wherein the air purification device is provided with a folding channel. After the air is driven into the folding channel, the dust and lint carried in the air are adsorbed and blocked by the folding channel, thereby achieving air purification.
[0009] Another advantage of this invention is that it provides an air purification device, wherein the air purification device is provided with an air guide channel, and the purified air gathers along the air guide channel and flows out of the air purification device together, thereby increasing the gas flow rate when the air flows out of the air purification device. When the purified air flows out of the outside, it further drives the surrounding unpurified air into the collection range of the air purification device.
[0010] Another advantage of this invention is that it provides an air purification device, wherein the air purification device is equipped with a dust collection tank for collecting dust and lint, and the dust collection tank can be disassembled and cleaned according to user needs.
[0011] Another advantage of this invention is that it provides an air purification device, wherein the air purification device is provided with multiple filter elements for filtering dust and lint, and the structural design for installing the filter elements facilitates the replacement of the filter elements by the user.

[0041] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0042] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.
[0043] like Figure 1 and Figure 2As shown, an air purification device 100 according to a preferred embodiment of the present invention includes: a top filter mechanism 10 and a drive mechanism 20. The top filter mechanism 10 has a first channel 101 and includes a cover 12 and a groove 11 disposed around the first channel 101. The groove 11 has a dust collection groove 111 with the top direction as the opening orientation. The cover 12 extends into the dust collection groove 111 to divide the top opening of the dust collection groove 111 into an outer opening 112 and an inner opening 113. The inner opening 113 communicates with the first channel 101.
[0044] The drive mechanism 20 is configured to drive the air in the first channel 101 to flow downward, so that external air can enter the first channel 101 through the dust collection groove 111 via the external opening 112 as the air inlet.
[0045] The air purification device 100 also includes a bottom filter mechanism 30. The drive mechanism 20 is used to drive the external air located above to enter the top filter mechanism 10 for filtration, and the external air located below to enter the bottom filter mechanism 30 for filtration. The filtered air flows outward between the top filter mechanism 10 and the bottom filter mechanism 30, further dividing the unpurified air around the air purification device 100 into an upper air zone and a lower air zone, and pushing the unpurified air in the upper air zone into the top filter mechanism 10, and pushing the unpurified air in the lower air zone into the bottom filter mechanism 30.
[0046] The cover 12 divides the dust collection tank 111 into a folded channel 102 that connects the outer opening 112 and the inner opening 113. In this way, when the dust collection tank 111 of the top filter mechanism 10 is filled with adsorbent, dust, lint, and soluble harmful gases in the outside air can be fully adsorbed by the adsorbent based on the folded shape of the folded channel 102.
[0047] The groove 11 and the cover 12 can be integrally formed or detachably connected, such as by threaded connection or snap-fit connection.
[0048] The bottom filtration mechanism 30 includes a filter frame 31, a support base 32, and an annular filter element 33. The annular filter element 33 is fixed to the support base 32 and is adapted to extend into the filter frame 31. The filter frame 31 has a plurality of filter holes arranged in an array. The support base 32 is detachably connected to the filter frame 31. The annular filter element 33 surrounds to form a second channel 301. The driving mechanism 20 drives the air in the second channel 301 to flow upward, so that external air can pass through the annular filter element 33 and enter the second channel 301 through the plurality of filter holes of the filter frame 31 as air inlets.
[0049] like Figure 2 and Figure 4 As shown, according to a preferred first embodiment of the utility model, the drive mechanism 20 includes a drive fan 21 and one or more spiral walls 22. The drive fan 21 is located between the top filter mechanism 10 and the bottom filter mechanism 30. The end of any spiral wall 22 near the drive fan 21 is defined as the proximal end. Any spiral wall 22 extends from its proximal end in a direction away from the drive fan 21 in a spiral direction.
[0050] The drive mechanism 20 further includes an air guide wall 23, which extends from the outer wall of any of the spiral walls 22 in the opposite direction of the spiral walls 22 in a direction away from the drive fan 21, and the air guide wall 23 and any of the spiral walls 22 surround each other to form an air guide channel 201.
[0051] like Figure 2 and Figure 3 As shown, the tank 11 is configured as an annular tank, and the top filter mechanism 10 further includes an annular cover 13. The annular cover 13 is located at the top opening of the dust collection tank 111 and is detachably connected to the tank 11. The annular cover 13 has an annular groove 131 with the opening facing the dust collection tank 111, and the top of the tank 11 has a filter port 114.
[0052] The ring cover 13 reduces the size of the outer opening 112, thereby increasing the gas flow rate when air enters the dust collection tank 111. As air enters the dust collection tank 111, lint and dust are less likely to float to the outside through the outer opening 112.
[0053] The adsorbent in the dust collection tank 111 is set to be liquid. When cleaning the dust collection tank 111, the top filter mechanism 10 is removed separately from the air purification device 100. The flowing liquid in the dust collection tank 111 is poured out through the filter port 233. The annular groove 131 of the ring cover 13 blocks and accommodates the clumps of lint and dust soaked in the liquid. Then, the ring cover 13 is removed from the tank body 11, the cover 12 is taken out, and all components of the top filter mechanism 10 are thoroughly cleaned.
[0054] The drive mechanism 20 further includes a frame 24, the spiral wall 22 is fixed to the frame 24, and the frame 24 includes an air outlet 241, such as... Figure 4 As shown, the air outlet 241 faces the air guide channel 201. The air driven by the driving fan 21 is purified and filtered by the top filter mechanism 10 and the bottom filter mechanism 30, and then flows and converges along the air guide channel 201 and flows out from the corresponding air outlet 241.
[0055] like Figure 5 and Figure 6 As shown, the frame 24 is provided with a top grid 242 and a bottom grid 243. The top grid 242 faces the top filter mechanism 10, and the bottom grid 243 faces the bottom filter mechanism 30. The frame 24 is detachably connected to the top filter mechanism 10 at the top and to the bottom filter mechanism 30 at the bottom.
[0056] Specifically, the frame 24 has a top snap-fit portion 244 and a bottom snap-fit portion 245, the groove 11 has a lower snap-fit portion 115 corresponding to the top snap-fit portion 244, so that the frame 24 and the groove 11 are detachably connected, and the filter frame 31 has an upper snap-fit portion 311 corresponding to the bottom snap-fit portion 245, so that the frame 24 and the filter frame 31 are detachably connected.
[0057] The filter frame 31 also includes a fixing member 312, which is arranged in an array on the filter frame 31. The fixing member 312 extends from the filter frame 31 toward the annular filter element 33 and is adapted to fix the position of the annular filter element 33 when the annular filter element 33 extends into the filter frame 31.
[0058] The filter frame 31 further includes a first latching part 313, and the support base 32 has a second latching part 321 corresponding to the first latching part 313. The support base 32 and the filter frame 31 are detachably connected through the first latching part 313 and the second latching part 321.
[0059] The support base 32 also includes a rotating part 322, which is disposed at the bottom of the support base 32. The rotating part 322 facilitates the user to rotate the support base 32 to install and disassemble the support base 32 and the filter frame 31, so as to partially disassemble the bottom filter mechanism 30 for cleaning or replacing the annular filter element 33.
[0060] like Figure 7 As shown, the air purification device 100 drives the airflow path during operation. The external air driven by the drive fan 21 enters the top filter mechanism 10 and the bottom filter mechanism 30 for purification. The air then converges in the air guide channel 201 and flows out from the air outlet 241. The purified air that converges and flows out has a high gas flow rate.
[0061] The external space extending from the air outlet 241 is defined as a segmentation zone. The purified air in the segmentation zone moves away from the air purifier 100 at a higher flow rate, and divides the unpurified air around the air purifier 100 into an upper air zone and a lower air zone. The lint and dust floating in the segmentation zone are impacted by the flowing air to leave the segmentation zone, and float to the upper air zone and the lower air zone respectively with the gas flow.
[0062] Driven by the drive fan 21, air from the upper air zone enters the folding channel 102 through the outer opening 112. Floss and dust in the air are adsorbed by the adsorbent in the folding channel 102. After passing through the folding channel 102, the air enters the first channel 101 through the inner opening 113 and flows downward from the first channel 101 to enter the air guide channel 201.
[0063] Air from the lower air zone enters the annular filter element 33 from the filter frame 31. Floss and dust in the air are blocked by the annular filter element 33. The air passes through the annular filter element and enters the second channel 301, and flows upward from the second channel 301 to enter the air guide channel 201.
[0064] Air from the first channel 101 and air from the second channel 301 converge in the air guide channel 201 and flow out from the air outlet 241 at a high flow rate, thereby enabling the air purification device 100 to fully drive the surrounding air to form a dual circulation flow path.
[0065] like Figure 8 As shown, a preferred second embodiment of the present invention is illustrated, wherein the cover 12 has a plurality of filter holes arranged in an array, and the top filter mechanism 10 further includes a filter element 14, which is disposed between the filter holes of the cover 12 and the inner opening 113 of the groove 11.
[0066] Driven by the drive mechanism 20, external air enters the first channel 101 through the filter holes of the cover 12 and the filter element 14 via the external opening 112. Dust and lint carried by the external air are blocked by the filter holes of the cover 12 and the filter element 14 and fall into the dust collection tank 111.
[0067] When cleaning the dust collection tank 111, the top filter mechanism 10 is removed separately from the air purification device 100, the ring cover 13 is removed from the tank body 11, the cover 12 and the filter element 14 are removed respectively, each component of the top filter mechanism 10 is thoroughly cleaned, and the filter element 14 is replaced with a new one.
[0068] According to a preferred third embodiment of the present invention, the drive mechanism 20 includes a first drive fan, a second drive fan, and one or more spiral walls 22. The first drive fan is located in the first channel 101, the second drive fan is located in the second channel 301, and any one of the spiral walls 22 is located between the top filter mechanism 10 and the bottom filter mechanism 30. The extension space of the first channel 101 is defined as the air guide space, and the end of any one of the spiral walls 22 near the air guide space is defined as the proximal end. Any one of the spiral walls 22 extends from its proximal end in a direction away from the air guide space in a spiral direction.
[0069] The drive mechanism 20 also includes an air guide wall 23, which extends from the outer wall of any of the spiral walls 22 in the opposite direction of the spiral walls 22 in a direction away from the air guide space, and the air guide wall 23 and any of the spiral walls 22 surround each other to form an air guide channel 201.
[0070] The first driving fan drives the air in the first channel 101 to flow downward, and the second driving fan drives the air in the second channel 301 to flow upward. The air converges in the air guide space and flows out along the air guide channel 201.
