[0002] Mite removal devices are cleaning equipment used to remove dust, mites, and other allergens from textiles such as beds, sofas, carpets, and clothing, and their use is increasing. When using a mite-removing vacuum cleaner, the bottom of the suction inlet contacts the surface being cleaned, thus drawing dust and mites into the dust cup. A mite-removing vacuum cleaner consists of a main body and a fan and roller brush housed within it. During cleaning, the suction inlet at the bottom of the main body contacts the surface being cleaned, and the roller brush is positioned at the suction inlet. The rolling and tapping action of the roller brush, combined with the suction provided by the fan, draws dust, mites, and other allergens from the suction inlet into the dust cup, achieving the mite and dust removal function.

[0039] Please see Figures 1 to 4 This application provides a mite removal device 100, which includes a dust collection cup 10, a housing 20, an air inlet 30, and an air outlet 40. The dust collection cup 10 is used to collect hair, dust, and other waste residue adsorbed by the mite removal device 100. A roller brush 21 is provided inside the housing 20, which is used to roll up hair, dust, and other waste residue on the surface to be cleaned. The air inlet 30 is located inside the housing 20 and has an integrally formed air inlet pipe 31. One end of the air inlet pipe 31 is connected to the roller brush 21, and the other end of the air inlet 30 is connected to the air inlet 11 of the dust collection cup 10. The air outlet 40 is located inside the housing 20 and is independently arranged from the air inlet 30. The air outlet 40 has an integrally formed air outlet pipe 41. One end of the air outlet pipe 41 is connected to the air outlet 12 of the dust collection cup 10, and the other end is connected to the heat dissipation vent on the housing 20.

[0040] When assembling the mite removal device 100, the roller brush 21, the air inlet component 30, and the air outlet component 40 are all installed inside the housing 20, with the air inlet duct 31 of the air inlet component 30 connected to the air inlet 11 of the dust collection cup 10, and the air outlet duct 41 of the air outlet component 40 connected to the air outlet 12 of the dust collection cup 10. When the mite removal device 100 is running, the roller brush 21 starts to rotate and rolls up dust, hair, and other waste on the surface to be cleaned. A large amount of dust adhering to the roller brush 21 is driven by the airflow into the air inlet duct 31 of the air inlet component 30, and then enters the dust collection cup 10 through the air inlet duct 31. The dust is finally left in the dust collection cup 10, and the airflow enters the air outlet duct 41 from the air outlet 12 of the dust collection cup 10 to leave the dust collection cup 10 and flow to the outside.

[0041] In summary, since both the air inlet duct 31 and the air outlet duct 41 are manufactured using an integrated molding process, the number of air inlet ducts 31 and 41 that need to be sealed can be reduced, thereby shortening the time required to assemble the air inlet component 30 and the air outlet component 40 and improving the installation efficiency of the mite removal equipment 100.

[0042] like Figure 4As shown, in some embodiments, the air inlet 30 includes a main body 32, which is recessed to form a receiving space. The receiving space contains a portion of the roller brush 21. An opening 321 is provided on the main body 32, which communicates with the receiving space. The air inlet duct 31 is located outside the receiving space and communicates with the main body 32 through the opening 321.

[0043] The main body 32 and the air inlet duct 31 are manufactured using an integral molding process. The size of the accommodating space is adapted to the size of the roller brush 21. When external dust and other waste enter the accommodating space formed by the main body 32 under the action of the roller brush 21, they can be completely blocked by the main body 32 to prevent dust from entering other areas of the housing 20. The dust accumulated in the accommodating space can only leave the area where the roller brush 21 is located through the opening 321, and then enter the air inlet duct 31.

[0044] In other words, the main body 32 can block the dust carried by the roller brush 21, causing it to concentrate in the containment space formed by the main body 32, and then enter the air inlet duct 31 through the opening 321, reducing the probability of dust spreading to other parts of the housing 20, and effectively maintaining the normal operation of the mite removal equipment 100.

[0045] Please continue reading. Figure 4 In some embodiments, the end of the air inlet duct 31 away from the opening 321 forms a first air outlet 311, which is connected to the air inlet 11; the air outlet duct 41 includes a first air inlet 411 and a second air outlet 412 that are arranged opposite to each other and connected. The first air inlet 411 and the first air outlet 311 are located on the same side of the main body 32 and are connected to the air outlet 12.

[0046] For example, such as Figure 4 As shown, the air inlet duct 31 extends away from the bottom wall of the housing 20. One end of the air inlet duct 31 connected to the opening 321 of the housing 20 is configured as the second air inlet end, and the other end is configured as the first air outlet end 311. The air outlet component 40 is located next to the air inlet component 30, and the first air inlet end 411 of the air outlet component 40 and the first air outlet end 311 of the air inlet component 30 are located on the same side.

[0047] In this embodiment of the application, the dust collection cup 10 (such as...) Figure 1 (As shown) can be a double-cup chamber structure. That is, the two cup chambers are connected and divided into a dust collection chamber and a cyclone chamber. The bottom of the dust collection chamber is provided with an air inlet 11, which is connected to the cyclone chamber. The cyclone chamber is equipped with a filter element, and its bottom is provided with an air outlet 12. When the mite removal device 100 is running, the dust adsorbed by the roller brush 21 enters the cyclone chamber through the air inlet 11 under the action of airflow and is filtered by the filter element. A large amount of dust in the cyclone chamber is thrown into the dust collection chamber under the action of centrifugal force, and the airflow leaves the dust collection cup 10 through the air outlet 12. In this way, the dust and the filter element are separated.

[0048] The above configuration places the first air inlet 411 and the first air outlet 311 together, which can appropriately reduce the volume of the dust collection cup 10 without affecting its performance.

[0049] In some embodiments, the first air outlet 311 is configured as a snap-fit ​​portion that snaps into the air inlet 11.

[0050] For example, the first air outlet 311 has a circumferential groove that is adapted to the air inlet 11 of the dust collection cup 10 so that the first air outlet 311 can extend into the air inlet 11 and engage with it.

[0051] When actually installing the dust collection cup 10, the air inlet 11 and the first air outlet 311 are positioned facing each other and snapped together, which simplifies the assembly method between the dust collection cup 10 and the air inlet component 30 and makes it easier to install and remove the dust collection cup 10.

[0052] Similarly, the first air inlet end 411 can also be constructed as a snap-fit ​​part, with a structure similar to that of the first air outlet end 311, so as to facilitate the installation of the dust collection cup 10.

[0053] In some embodiments, the air outlet 40 and the main body 32 are detachably connected.

[0054] For example, the air outlet 40 and the main body 32 may be connected by, but are not limited to, snap-fit ​​or threaded connections. When at least one of the air outlet 40 and the air inlet 30 is damaged, the damaged part can be replaced with a new one. This reduces the maintenance cost of the mite removal device 100.

[0055] like Figure 5 and Figure 6 As shown, in some embodiments, the main body 32 is provided with a limiting part 322, and the air outlet 40 is provided with a mating part 42. The mating part 42 is sleeved on the outside of the limiting part 322, and the mating part 42 is fixed on the limiting part 322 by the limiting member.

[0056] For example, a columnar sleeve protrudes from the main body 32, and the columnar sleeve is configured as a limiting part 322 and is located next to the first air outlet 311. An annulus is provided on the air outlet member 40, and the annulus is configured as a mating part 42 and is located next to the first air inlet 411.

[0057] When assembling the air outlet component 40, the mating part 42 on the air outlet component 40 can be fitted over the limiting part 322 on the main body 32, and the mating part 42 can be fixed by using a limiting member (such as a retainer) to lock onto the end of the limiting part 322. In this way, by directly providing the limiting part 322 on the main body 32 to fix the air outlet component 40, the connection stability between the two is improved, and the probability of the installation stability of the dust collection cup 10 being affected by the separation of the first air inlet end 411 and the first air outlet end 311 is reduced. Moreover, by setting the limiting part 322 on the main body 32, there is no need to occupy the area inside the housing 20 other than the air inlet component 30, thereby saving the internal space of the housing 20. The saved space can be used to install other equipment of the mite removal device 100, or to reduce the size of the mite removal device 100.

[0058] It should be noted that, in order to further improve the connection stability between the mating part 42 and the limiting part 322, protruding ribs can be provided on the outer wall of the limiting part 322 at intervals, so that the mating part 42 can be firmly locked onto the limiting part 322.

[0059] In some embodiments, the mite removal device 100 includes a top cover (not shown), which covers the housing 20 and together with the housing 20 forms a receiving cavity. The receiving cavity contains a roller brush 21, an air inlet 30, and an air outlet 40. Please refer to [link to documentation]. Figure 6 The air inlet component 30 also includes a fixing component 33, which is located on the main body 32 and is detachably connected to the upper cover.

[0060] like Figure 6 As shown, the main body 32 is provided with multiple buckles, which are constructed as fasteners 33. After the roller brush 21, air inlet 30 and air outlet 40 are assembled into the housing 20, the top cover is closed with the housing 20, and the top cover is engaged with the buckles.

[0061] When the roller brush 21 is running, the air inlet component 30 is connected to the housing 20 and the top cover, so the air inlet component 30 can be fixed in multiple directions, which improves the installation stability of the air inlet component 30 and reduces the probability of the air inlet component 30 shaking under the impact of the waste residue rolled by the roller brush 21.

[0062] Please see Figure 5 and Figure 6 In some embodiments, the main body 32 includes a connecting portion 323 and sidewalls 324 connected to both ends of the connecting portion 323. Along a direction perpendicular to the housing 20, the sidewalls 324 protrude relative to the connecting portion 323 to form a first positioning portion 3241, which is located in the positioning groove (not shown in the figure) of the housing 20.

[0063] For example, the connecting portion 323 is recessed in an arc shape on the surface facing the roller brush 21 to fit the roller brush 21. Along a direction perpendicular to the housing 20, the sidewall 324 protrudes to form an arc-shaped first positioning portion 3241, which can extend into a positioning groove in the housing 20. This increases the contact area between the main body 32 and the housing 20, improves the connection stability between the main body 32 and the housing 20, and reduces the probability of the air inlet 30 shaking. Furthermore, the main body 32 can be used to limit the roller brush 21 in its extension direction, reducing the probability of the roller brush 21 moving in its extended direction.

[0064] In other embodiments, the connecting portion 323 may also have a groove on the side facing the bottom wall of the housing 20, which can cooperate with the bottom wall of the housing 20 to fix the connecting portion 323.

[0065] Furthermore, such as Figure 4 and Figure 5 As shown, in some embodiments, the air inlet 30 further includes a second positioning part 3242, which is disposed on the side of the side wall 324 away from the first positioning part 3241. The second positioning part 3242 protrudes relative to the main body 32 and is sleeved on the fixing part 33 of the housing 20.

[0066] For example, the side wall 324 protrudes outward to form a ring, and the bottom wall of the housing 20 protrudes to form a fixing member 33. When the air inlet 30 is installed inside the housing 20, the ring can be fitted over the fixing member 33. By providing positioning parts at different locations on the side wall 324, the side wall 324 can be positioned in multiple directions, improving the connection stability between the side wall 324 and the housing 20.

[0067] Furthermore, such as Figure 4 As shown, in some embodiments, one of the side walls 324 is provided with a mounting cylinder 3243, which extends vertically from the side wall 324 and communicates with the receiving space. A locking member 34 is engaged inside the mounting cylinder 3243, and a spring 35 is sleeved inside the locking member 34. One end of the roller brush 21 is rotatably engaged in the spring 35, and the other end of the roller brush 21 passes through the other side wall 324 and is connected to the roller brush 21 drive member.

[0068] For ease of explanation, one of the two sidewalls 324 is designated as the first sidewall 324, and the other as the second sidewall 324. The first sidewall 324 has a through hole, and the inner wall of the through hole is provided with a sealing ring fixing rib 36. A fixing part is provided on the surface of the first sidewall 324 opposite to the second sidewall 324, and the fixing part is used to position the roller brush 21 drive component. That is, the roller brush 21 drive component is assembled on the first sidewall 324, and its drive shaft passes through the through hole and connects to the roller brush 21, driving the roller brush 21 to rotate.

[0069] A mounting cylinder 3243 is provided on the second sidewall 324. The mounting cylinder 3243 is located on the surface of the second sidewall 324 opposite to the first sidewall 324 and extends perpendicularly to the second sidewall 324. The inner wall of the mounting cylinder 3243 is provided with ribs, and the locking member 34 is fixed inside the mounting cylinder 3243 by the ribs. The spring 35 is provided inside the locking member 34 and is connected to the end of the roller brush 21 away from the roller brush 21 drive member.

[0070] In other words, one end of the roller brush 21 passes through the first sidewall 324 and is connected to the roller brush 21 drive member, while the other end passes through the second sidewall 324 and is connected to the spring 35 inside the locking member 34. When the roller brush 21 drive member drives the roller brush 21 to rotate, the locking member 34 and the spring 35 can limit the end of the roller brush 21 and help the roller brush 21 run smoothly.

[0071] Secondly, the surface of the second sidewall 324 facing the first sidewall 324 is recessed to form a fixing groove, and the bottom wall of the fixing groove is provided with an mounting cylinder 3243. When installing the roller brush 21, the end of the roller brush 21 passes through the fixing groove and then enters the mounting cylinder 3243. Finally, a baffle is used to block the fixing groove to prevent the end of the roller brush 21 from coming out of the fixing groove. The fixing groove is provided to facilitate the assembly of the roller brush 21.

[0072] In other embodiments, such as Figure 4 As shown, the outer wall of the air inlet duct 31 is also provided with mounting holes, which can be used to install dust mite detection lamps 37 and to detect the presence of dust mites.

[0073] like Figure 7 As shown, in some embodiments, the air outlet 40 is provided with a fixing post 43, which extends in a direction perpendicular to the bottom wall of the housing 20 and is connected to the housing 20.

[0074] For example, the bottom wall of the housing 20 is provided with a slot (not shown in the figure). When the air outlet 40 is installed in the housing 20, in addition to being able to connect with the air inlet 30, the fixing post 43 of the air outlet 40 is engaged with the slot of the housing 20.

[0075] This configuration allows the air outlet component 40 to be connected to different components, improving the installation stability of the air outlet component 40.

[0076] Please continue reading. Figure 6 In some embodiments, the air outlet 40 is provided with a first wire-locking part 44, and a wire-locking groove is formed between the first wire-locking part 44 and the air outlet 40.

[0077] The cable tray can be used to hold the wires of the mite removal device 100, such as the display screen assembly wiring and the drive component wiring, so as to reduce the messy distribution of wires inside the housing 20 and facilitate the installation of various components of the mite removal device 100.

[0078] Of course, a second cable clamping part 45 can also be provided on the air outlet part 40 (such as...). Figure 7 As shown), the wires of the dust mite detection lamp 37 can be fixed using the second wire clamping part 45.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
