Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air intake filter mechanism of an indoor unit of an air conditioner and an air conditioner. Background Art

[0002] At the air inlet of the air conditioner indoor unit, a filter is usually set to filter the air entering the air conditioner indoor unit and reduce the dust entering the air conditioner. As the filter is used continuously, the dust on it gradually accumulates. When it accumulates to a certain extent, it will significantly weaken the air intake efficiency. For this reason, some existing air conditioners are equipped with a filter that can be rolled up and unrolled. That is, if there is too much dust on a part of the filter, this part of the filter will be rolled up, and a part of the new filter will be released to the air inlet, thereby controlling the air intake resistance of the air conditioner indoor unit.

[0003] However, the dust on the rolled filter may also fall off the filter and fall into the interior of the air conditioner indoor unit. Although some air conditioners use a brush to brush off the dust on the filter, the compression degree of the brush increases significantly as the filter rolls up, and the brush is easily damaged. Summary of the invention

[0004] The first object of the present invention is to provide an air intake filter mechanism for an indoor unit of an air conditioner to solve the technical problem that the existing dust removal brush for cleaning the filter is easily damaged.

[0005] The air intake filter mechanism of the indoor unit of an air conditioner provided by the present invention comprises a filter, a winding assembly, an upper cover and a dust removal assembly, wherein the winding assembly is arranged in the upper cover, and the winding assembly comprises a winding shaft fixedly connected to one end of the filter; the dust removal assembly comprises a dust collecting box and a dust removal brush, wherein the dust collecting box is connected to the upper cover and corresponds to the winding assembly, and the dust removal brush is configured to be driven to move by the circumferential surface of the filter wound on the winding shaft.

[0006] The beneficial effects brought by the air intake filter mechanism of the air conditioner indoor unit of the present invention are:

[0007] By configuring the dust removal brush to be driven by the circumference of the filter screen wound on the reel, when the reel winds up the filter screen, the diameter of the filter screen wound on the reel increases, and the dust removal brush is driven by the circumference of the filter screen and moves away from the axis of the reel. As a result, the pressure of the dust removal brush on the outer circumference of the filter screen can be kept relatively stable, and the bristles of the dust removal brush will not be damaged due to the increase in the number of filter screens wound on the reel and the increase in the reel diameter, which is conducive to improving the service life of the dust removal component and ensuring that the reeled filter screen can be effectively cleaned.

[0008] In a preferred technical solution, the dust removal assembly further includes an elastic member, one end of which is connected to the dust collecting box, and the other end of which abuts against the dust removal brush.

[0009] By connecting one end of the elastic member to the dust box and the other end against the dust removal brush, a force can be applied to the dust removal brush so that the bristles of the dust removal brush contact the bristles wound on the winding shaft and maintain appropriate force, thereby improving the cleaning ability of the dust on the filter.

[0010] In a preferred technical solution, the dust removal brush and the dust collection box are arranged to slide relative to each other, and one of the inner wall end surface of the dust collection box and the end of the dust removal brush is provided with a convex guide part, and the other is provided with a concave guide part, and the convex guide part cooperates with the concave guide part.

[0011] By arranging a guide structure composed of a matching convex guide part and a concave guide part between the inner wall end face of the dust collecting box and the end of the dust removal brush, it can be ensured that when the dust removal brush moves up and down during being squeezed by the filter, it will not swing around the length direction of the dust removal brush or swing within the radial and axial planes of the winding shaft, so that the bristles on the dust removal brush can contact the filter more evenly, avoiding excessive local bristle pressure due to the tilt of the dust removal brush.

[0012] In a preferred technical solution, a guide groove is provided on the inner wall end surface of the dust collecting box, the convex guide portion is arranged at the end of the dust removal brush, and an anti-slip structure is provided on the top of the guide groove.

[0013] By providing an anti-slip structure at the top of the guide groove, the convex guide portion of the dust removal brush can be prevented from moving too far in the guide groove, thereby limiting the maximum distance the dust removal brush can move upward, preventing the dust removal brush from being driven by the elastic part and applying too much distance to the filter, thereby avoiding excessive pressure between the bristles of the dust removal brush and the filter, causing damage to the bristles.

[0014] In a preferred technical solution, the elastic member is a spring sheet, both ends of the spring sheet in the length direction abut against the inner wall of the bottom of the dust collecting box, and the middle part of the spring sheet abuts against the dust removal brush.

[0015] Since the increase in the diameter of the filter screen is long-term and continuous, the elastic part needs to be subjected to long-term stress. The use of spring clips as the elastic part can well adapt to such long-term stress environment. By making the two ends of the spring clip abut against the inner wall of the bottom of the dust box in the length direction and the middle of the spring clip abut against the dust brush, the dust brush has a larger area to receive the force of the spring clip, which can improve the stability of the force on the dust brush, so that the dust brush can apply force to the filter screen more evenly in its length direction, improving the cleaning effect of the dust attached to the filter screen.

[0016] In a preferred technical solution, a first positioning column is provided on a side of the dust removal brush facing the elastic member, a positioning hole is provided on the elastic member, and the first positioning column matches the positioning hole.

[0017] By setting a first positioning column to cooperate with the first positioning hole on the elastic member, the horizontal position of the dust brush can be controlled by utilizing the cooperation between the dust brush and the dust box, and then the horizontal position of the dust brush can be used to limit the horizontal position of the elastic member, thereby preventing the elastic member from moving in the horizontal direction.

[0018] In a preferred technical solution, the dust removal brush is provided with a first latching tongue, the elastic member is provided with a first latching hole, and the first latching tongue is latched in the first latching hole.

[0019] By arranging the first clamping tongue of the dust removal brush to be clamped in the first clamping hole, not only the rotation of the elastic member relative to the dust removal brush is restricted, but also the elastic member can be prevented from falling away from the dust removal brush downward, thereby improving the reliability of the dust removal assembly.

[0020] In a preferred technical solution, the dust box is provided with a second latch tongue on the side of the winding direction of the filter, the upper cover is provided with a second latch hole, and the second latch tongue is latched in the second latch hole; the dust box is provided with a third latch tongue on the side of the unfolding direction of the filter, the upper cover is provided with a third latch hole, and the third latch tongue is latched in the third latch hole; at least one of the second latch tongue and the third latch tongue is exposed from the upper cover.

[0021] By setting a combination of the second latch and the second latch hole, and the cooperation of the third latch and the third latch hole, one side of the dust box in the winding direction and one side of the dust box in the unwinding direction can be respectively fixed to the upper cover, so as to ensure that the dust box can be reliably installed on the upper cover. Moreover, by exposing at least one of the second latch or the third latch from the upper cover, when the dust box needs to be removed from the upper cover, the corresponding second latch and / or third latch can be pressed through the second latch hole and / or the third latch hole of the upper cover to contact the fixation between the latch and the latch hole, so that the side of the dust box can be separated from the upper cover, and then the other side can be separated very conveniently, thereby improving the convenience of removing the dust box, and facilitating more convenient cleaning of dust in the dust box, so as to ensure the cleanliness of the dust box.

[0022] In a preferred technical solution, an inner wall of the dust collecting box is provided with a second positioning column protruding upward, and the second positioning column is arranged corresponding to the third latch tongue.

[0023] By setting a second positioning column corresponding to the third latch tongue, the third latch tongue can be prevented from moving in a direction away from the second latch hole, especially when the second latch tongue and the third latch tongue are in the same clamping direction relative to the second latch hole and the third latch hole, the dust box can only be limited in the positive direction of a certain horizontal direction, but cannot be limited in the reverse direction of the horizontal direction. The second positioning column is used for limiting the position to prevent the dust box from falling off the upper cover.

[0024] The second object of the present invention is to provide an air conditioner to solve the technical problem that the dust removal brush for cleaning the filter is easily damaged.

[0025] The air conditioner provided by the present invention comprises an air conditioner indoor unit, wherein the air conditioner indoor unit comprises an air inlet and any one of the air conditioner indoor unit air inlet filter mechanisms described above, wherein the air conditioner indoor unit air inlet filter mechanism is arranged at the air inlet.

[0026] By providing the above-mentioned air intake filter mechanism for the indoor unit of the air conditioner in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned air intake filter mechanism for the indoor unit of the air conditioner, which will not be described in detail here.

DETAILED DESCRIPTION

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] Embodiment 1:

[0046] Figure 1 A schematic diagram of the structure of an air intake filter mechanism for an indoor unit of an air conditioner provided in Embodiment 1 of the present invention; Figure 2 A schematic structural diagram of an air intake filter mechanism for an indoor unit of an air conditioner provided in the first embodiment of the present invention viewed from another direction; Figure 3A schematic diagram of a partially disassembled air intake filter mechanism of an indoor unit of an air conditioner provided in Embodiment 1 of the present invention; Figure 4 A three-dimensional disassembled diagram of an air intake filter mechanism of an indoor unit of an air conditioner provided in Embodiment 1 of the present invention; Figure 5 This is a three-dimensional disassembled diagram of the air intake filter mechanism of the air conditioner indoor unit provided in the first embodiment of the present invention as viewed from another direction; Figure 1-Figure 5 As shown, the air intake filtration mechanism of the indoor unit of the air conditioner provided in the first embodiment of the present invention includes a filter 100, a winding assembly 200, an upper cover 300 and a dust removal assembly 400. The winding assembly 200 is arranged in the upper cover 300, and the winding assembly 200 includes a winding shaft 210 fixedly connected to one end of the filter 100; the dust removal assembly 400 includes a dust box 410 and a dust removal brush 420, the dust box 410 is connected to the upper cover 300 and corresponds to the winding assembly 200, and the dust removal brush 420 is configured to be driven by the circumferential surface of the filter 100 wound on the winding shaft 210 to move.

[0047] The air conditioner indoor unit used in this embodiment is a wall-mounted air conditioner indoor unit, and the air inlet of the wall-mounted air conditioner indoor unit is arranged at the top of the body. The upper cover 300 is installed on the top of the middle frame. The upper cover 300 mainly has two accommodating spaces, the first accommodating space and the second accommodating space. The first accommodating space is mainly used to accommodate the unwinding component, and the second accommodating space is mainly used to accommodate the winding component 200. The dust box 410 is arranged corresponding to the winding component 200. Specifically, the dust box 410 is located below the second accommodating space and is connected to this part of the upper cover 300.

[0048] In this embodiment, a dust removal brush 420 is movably provided in the dust box 410, and the dust removal brush 420 maintains contact with the filter 100 wound on the winding shaft 210, so that when the winding shaft 210 rotates, the bristles 423 can be used to clean the dust and the like on the filter 100 wound on the winding shaft 210.

[0049] By configuring the dust removal brush 420 to be driven by the circumference of the filter 100 wound on the reel 210 to move, when the reel 210 winds the filter 100, the diameter of the filter 100 wound on the reel 210 increases, and the dust removal brush 420 is driven by the circumference of the wound filter 100 and moves away from the axis of the reel 210. As a result, the pressure of the dust removal brush 420 on the outer circumference of the filter 100 can be kept relatively stable, and the pressure will not be significantly increased due to the increase in the number of filter screens 100 wound on the reel 210 and the increase in the diameter of the reel, thereby damaging the bristles 423 of the dust removal brush 420, which is conducive to improving the service life of the dust removal assembly 400 and ensuring that the rolled filter 100 can be effectively cleaned.

[0050] like Figure 4 and Figure 5As shown, preferably, the dust removal assembly 400 further includes an elastic member 430 , one end of the elastic member 430 is connected to the dust collecting box 410 , and the other end of the elastic member 430 abuts against the dust removal brush 420 .

[0051] It should be noted that one end of the elastic member 430 and the other end of the elastic member 430 in this embodiment do not refer to the opposite ends of the elastic member 430 in its length direction. It is possible that the opposite ends of the elastic member 430 in its length direction are both connected to the dust collecting box 410 and are both regarded as one end of the elastic member 430, and the middle part of the elastic member 430, that is, the other end of the elastic member 430, abuts against the dust removal brush 420.

[0052] Among them, the dust removal brush 420 includes a brush body 421 and bristles 423. A plurality of bristles 423 are arranged in a matrix on the brush body 421. The brush body 421 abuts against the elastic member 430. The bristles 423 contact the peripheral surface of the filter 100 to brush off dust and the like attached to the filter 100.

[0053] By connecting one end of the elastic member 430 to the dust box 410 and the other end to the dust brush 420, a force can be applied to the dust brush 420 so that the bristles 423 of the dust brush 420 are in contact with the dust wound on the winding shaft 210 and maintain an appropriate force, thereby improving the cleaning ability of the dust on the filter 100.

[0054] In another implementation, the elastic member 430 may not be provided, for example, gravity may be used to drive the end of the bristles 423 of the dust removal brush 420 to keep in contact with the peripheral surface of the filter 100. Specifically, a groove extending downwardly and penetrating downwardly may be provided at the end of the upper shell, and the dust removal brush 420 may be slidably arranged in the groove. The force generated by gravity may cause the dust removal brush 420 to slide downwardly so that the bristles 423 may contact the filter 100. The dust and the like that can be brushed off the filter 100 by the bristles 423 may fall into the dust collection box 410 from the horizontal side of the filter 100.

[0055] like Figure 6 and Figure 7 As shown, preferably, the dust removal brush 420 is arranged to slide relative to the dust collecting box 410, and one of the inner wall end surface of the dust collecting box 410 and the end of the dust removal brush 420 is provided with a convex guide portion 425, and the other is provided with a concave guide portion, and the convex guide portion 425 cooperates with the concave guide portion.

[0056] Specifically, in this embodiment, the dust removal brush 420 is roughly in the shape of a gate, and the length of the top beam of the gate is significantly greater than the height of the gate. Bristles 423 are provided on the upper surface of the top beam of the gate, and a guide structure in which a convex guide part 425 and a concave guide part cooperate with each other is provided between the two arms of the gate and the inner wall end surface of the dust collection box 410. Of course, in this embodiment, in order to strengthen the rigidity of the brush body 421, a reinforcing rib can be provided on the bottom surface of the brush body 421.

[0057] By providing a guiding structure consisting of a matching convex guide portion 425 and a concave guide portion between the inner wall end surface of the dust box 410 and the end of the dust brush 420, it can be ensured that when the dust brush 420 moves up and down during being squeezed by the filter 100, it will not swing around the length direction of the dust brush 420 as the axis, or swing within the radial and axial planes of the winding shaft 210, so that the bristles 423 on the dust brush 420 can contact the filter 100 more evenly, avoiding excessive pressure on the local bristles 423 due to the tilt of the dust brush 420.

[0058] In another implementation, if the guide structure described later is not adopted, a guide ridge serving as a convex guide portion 425 can be provided on the inner wall end face of the dust box 410, and a guide notch serving as a concave guide portion matching the guide ridge can be provided on the end face of the dust brush 420. The guide notch can slide along the guide ridge to ensure that the dust brush 420 does not tilt during movement.

[0059] like Figure 7 As shown, preferably, a guide groove 411 is provided on the inner wall end surface of the dust collecting box 410, a convex guide portion 425 is provided at the end of the dust removal brush 420, and an anti-slip structure is provided on the top of the guide groove 411.

[0060] Among them, in this embodiment, the convex guide portion 425 is arranged on the opposite sides of the bottom of the two arms of the gate shape of the dust removal brush 420, and the convex guide portion 425 is matched with the guide groove 411 serving as the concave guide portion in the horizontal plane, that is, the two ends of the convex guide portion 425 along the axial direction of the winding shaft 210 are in contact with the groove bottom corresponding to the guide groove 411, and the two side surfaces of the convex guide portion 425 along the circumferential direction of the winding shaft 210 are in contact with the groove wall of the guide groove 411.

[0061] The anti-slip structure at the top of the guide groove 411 is a blocking piece at the top of the guide groove 411 , and the blocking piece can prevent the convex guide portion 425 from continuing to move upward.

[0062] By providing an anti-slip structure at the top of the guide groove 411, the convex guide portion 425 of the dust removal brush 420 can be prevented from moving too far in the guide groove 411, thereby limiting the maximum distance that the dust removal brush 420 can move upward, preventing the dust removal brush 420 from being driven by the elastic member 430 and applying too much distance to the filter 100, thereby avoiding excessive pressure between the bristles 423 of the dust removal brush 420 and the filter 100, causing damage to the bristles 423.

[0063] like Figure 7 As shown, preferably, the elastic member 430 is a spring sheet, both ends of the spring sheet in the length direction abut against the inner wall of the bottom of the dust collecting box 410 , and the middle part of the spring sheet abuts against the dust removal brush 420 .

[0064] In this embodiment, the spring piece can be an arch or an isosceles trapezoid, wherein the two ends of the spring piece in the length direction are directly placed on the inner wall of the bottom of the dust box 410, and there is no limit between the spring piece and the dust box 410 in the length direction. When the deformation of the spring piece increases, the height of the spring piece becomes thinner, and the two ends of the spring piece in the length direction become farther, and the entire spring piece becomes flatter. The lower surface of the brush body 421 of the dust removal brush 420 is roughly flat, matching the shape of the top surface of the middle part of the length direction of the spring piece, thereby increasing the contact area and improving the stability of the dust removal brush 420.

[0065] In the solution of the present application, since the increase process of the diameter of the filter 100 is long-term and continuous, the elastic member 430 needs to be subjected to force for a long time. The use of a spring as the elastic member 430 can well adapt to such a long-term force environment. By making the two ends of the spring in the length direction abut against the inner wall of the bottom of the dust box 410, and the middle of the spring abut against the dust brush 420, the dust brush 420 has a larger area to receive the force of the spring, which can improve the stability of the force of the dust brush 420, so that the dust brush 420 can apply force to the filter 100 more evenly in its length direction, and improve the cleaning effect of the dust attached to the filter 100.

[0066] Of course, in another implementation, a cylindrical helical compression spring may also be used as the elastic member 430 to support the dust removal brush 420 .

[0067] like Figure 8 and Fig. 9 As shown, preferably, a first positioning column 427 is provided on the side of the dust removal brush 420 facing the elastic member 430 , and a positioning hole 431 is provided on the elastic member 430 , and the first positioning column 427 matches the positioning hole 431 .

[0068] Specifically, the first positioning column 427 may be disposed at a central position of a side surface of the dust removal brush 420 facing the elastic member 430 .

[0069] By setting a first positioning column 427, which cooperates with the first positioning hole 431 on the elastic member 430, the horizontal position of the dust removal brush 420 can be controlled by utilizing the cooperation between the dust removal brush 420 and the dust collection box 410, and then the horizontal position of the dust removal brush 420 can be utilized to limit the horizontal position of the elastic member 430, thereby preventing the elastic member 430 from moving in the horizontal direction.

[0070] like Figure 8 and Fig. 9 As shown, preferably, the dust removal brush 420 is provided with a first latching tongue 429 , the elastic member 430 is provided with a first latching hole 433 , and the first latching tongue 429 is latched in the first latching hole 433 .

[0071] Specifically, the dust removal brush 420 is provided with two first latching tongues 429 protruding downward, and correspondingly, the elastic member 430 is provided with two first latching holes 433 at positions corresponding thereto. The first positioning column 427 is located between the two first latching tongues 429, and the tip portions of the wedge-shaped portions of the two first latching tongues 429 protrude downward, and the larger thickness portions of the two wedge-shaped portions protrude in opposite horizontal directions.

[0072] More specifically, since the elastic member 430 is a metal spring sheet, the bent portion 435 generated when processing the first clamping hole 433 can be matched with the wedge-shaped portion of the first clamping tongue 429 respectively, and are respectively located above the two wedge-shaped portions to prevent the first clamping tongue 429 from being disengaged from the first clamping hole 433.

[0073] By setting the first latch tongue 429 of the dust removal brush 420 to be latched in the first latch hole 433, not only the rotation of the elastic member 430 relative to the dust removal brush 420 is limited, but also the elastic member 430 can be prevented from downwardly separating from the dust removal brush 420, thereby improving the reliability of the dust removal assembly 400.

[0074] like Figure 1 , Figure 2 and Fig.10 , Fig.11 As shown, preferably, the dust box 410 is provided with a second latch tongue 415 on the side of the winding direction of the filter 100, the upper cover 300 is provided with a second latch hole 310, and the second latch tongue 415 is latched in the second latch hole 310; the dust box 410 is provided with a third latch tongue 417 on the side of the unfolding direction of the filter 100, the upper cover 300 is provided with a third latch hole 320, and the third latch tongue 417 is latched in the third latch hole 320; at least one of the second latch tongue 415 and the third latch tongue 417 is exposed from the upper cover 300.

[0075] The dust box 410 may include a substantially semicircular circumferential surface portion and a semicircular end surface portion, and the second latch 415 is disposed on one side of the semicircular circumferential surface portion close to the two ends of the side. Fig.10The right side in the figure is the winding direction of the filter screen 100 on the winding assembly 200. A second clamping hole 310 corresponding to the position is provided on the upper cover 300, and the second clamping hole 310 can be located at the lower part of the corresponding side of the upper cover 300. Specifically, the second clamping tongue 415 is a clamping tongue protruding upward, that is, the wedge-shaped portion of the second clamping tongue 415 is narrow at the top and thick at the bottom, and the second clamping hole 310 is a through hole that penetrates the upper cover 300 along the wall thickness direction. More specifically, the penetration direction of the second clamping hole 310 is close to the horizontal direction. In this embodiment, the second clamping tongue 415 is exposed from the upper cover 300, that is, the second clamping tongue 415 can be observed from above the upper cover 300.

[0076] The third latch 417 is located on the other side of the semicircular surface of the dust box 410, that is, Fig.10 The left side shown, i.e. Fig.10 The third clamping hole 320 is arranged at a position corresponding to the third clamping tongue 417. Specifically, a plate-shaped portion protruding downward in the vertical direction is arranged on the upper cover 300, and the third clamping hole 320 penetrating in the horizontal direction is processed on the plate-shaped portion, and the thicker part of the wedge-shaped portion of the third clamping tongue 417 matches the third clamping hole 320.

[0077] By setting a combination of the second latch tongue 415 and the second latch hole 310, and the cooperation of the third latch tongue 417 and the third latch hole 320, one side of the dust box 410 in the winding direction and one side of the dust box 410 in the unwinding direction can be fixed to the upper cover 300 respectively, to ensure that the dust box 410 can be reliably installed on the upper cover 300. Moreover, by exposing at least one of the second latch 415 or the third latch 417 from the upper cover 300, when the dust box 410 needs to be removed from the upper cover 300, the corresponding second latch 415 and / or third latch 417 can be pressed through the second latch hole 310 and / or the third latch hole 320 of the upper cover 300 to contact the fixation between the latch and the latch hole, so that the side of the dust box 410 can be separated from the upper cover 300, and then the other side can be separated very conveniently, thereby improving the convenience of removing the dust box 410 and facilitating more convenient cleaning of the dust in the dust box 410 to ensure the cleanliness of the dust box 410.

[0078] like Fig.10 and Fig.11 As shown, preferably, the inner wall of the dust box 410 is provided with a second positioning column 419 protruding upward, and the second positioning column 419 is arranged corresponding to the third latch tongue 417.

[0079] The second positioning column 419 and the third latch tongue 417 are disposed correspondingly, which means that the second positioning column 419 and the plate body of the third latch tongue 417 are respectively located at opposite sides of the plate-shaped portion where the second latch hole 310 is disposed.

[0080] By providing a second positioning column 419 corresponding to the third latch tongue 417, the third latch tongue 417 can be prevented from moving in a direction away from the second latch hole 310, especially when the second latch tongue 415 and the third latch tongue 417 are in the same latching direction relative to the second latch hole 310 and the third latch hole 320, the dust box 410 can only be limited in the positive direction of a certain horizontal direction, but cannot be limited in the reverse direction of the horizontal direction. The second positioning column 419 is used for limiting to prevent the dust box 410 from falling off the upper cover 300.

[0081] The operating principle of this embodiment is:

[0082] As the winding shaft 210 is wound around the filter 100, the filter 100 rotates relative to the dust brush 420, and the bristles 423 of the dust brush 420 clean the dust attached to the surface of the filter 100. As the winding length of the filter 100 increases, the winding diameter of the filter 100 also increases. Since the lower part of the dust brush 420 is supported by the elastic member 430, the dust brush 420 can move downward under the action of the outer peripheral surface of the filter 100 and compress the elastic member 430. As the distance between the two ends of the elastic member 430 in the length direction increases, the height of the elastic member decreases. Although as the winding diameter of the filter 100 increases, the deformation of the elastic member 430 will also increase, and the force of the elastic member 430 on the dust brush 420 will increase. However, since the elastic member 430 is elastic and can be deformed, the degree of increase in the force of the bristles 423 on the filter 100 is limited, ensuring that the bristles 423 will not be significantly damaged.

[0083] If the dust box 410 needs to be removed, the second latching tongue 415 can be pressed from the outside of the second latching hole 310 of the upper cover 300 to contact the locking of the second latching tongue 415 by the second latching hole 310. Fig.10 The right side of the cover 300 is separated from the cover 300. Fig.10 By pushing and shaking the dust box 410 on the left side of Fig.10 The fixing of the third latching tongue 417 on the left side and the third latching hole 320 is released, so the dust collecting box 410 can be separated from the upper cover 300. The dust collecting box 410 can be cleaned separately.
