Description

Technical Field

[0001] This utility model relates to the field of dust removal devices, specifically to an air purifier with a structure for removing impurities and its application. Background Technology

[0002] An air purifier is a device used to remove common indoor pollutants, thereby improving indoor air quality.

[0003] The working principle of an air purifier is to install a fan between the air inlet and the air outlet, and a filter between the fan and the air inlet. When the fan operates, it drives the air to flow from the air inlet to the air outlet. After the air passes through the filter and common pollutants are filtered out, clean air is discharged.

[0004] However, after long-term use, pollutants accumulate on the filters in existing technologies, which reduces the efficiency of air purifiers and increases energy consumption, requiring users to replace or clean the filters regularly. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an air purifier with a structure for removing impurities that can reduce the frequency of filter replacement and its application.

[0006] The first technical solution adopted by this utility model to solve its technical problem is:

[0007] An impurity removal structure, comprising:

[0008] The roller core has an adhesive layer on its outer surface, which is used to adhere contaminants on the filter element;

[0009] A roller core fixing seat is arranged adjacent to the roller core along the radial direction of the roller core, and is rotatably connected to the roller core at both ends along the axial direction of the roller core.

[0010] The roller core fixing seat also includes fixing covers disposed on both sides of the roller core along the radial direction of the roller core. The side of the fixing cover closest to the roller core is the first side. The fixing cover, the roller core and the roller core fixing seat together form a receiving cavity for accommodating contaminants. Rotating the roller core allows the contaminants adhered to the adhesive layer to be collected and accumulated in the receiving cavity.

[0011] As described above, in the impurity removal structure, the material used to make the adhesive layer includes lint-removing cloth. When the roller core is rotated, the lint-removing cloth rubs against the first surface to cause the adhered hair to accumulate in the receiving cavity.

[0012] As described above, the impurity removal structure further includes a scraping layer disposed on the first surface, wherein the scraping layer is provided with a plurality of first filamentous structures, which are arranged in the direction of the receiving cavity.

[0013] As described above, in the impurity removal structure, a limiting block is provided on the outer surface of the roller core. The limiting block is used to abut against the fixed cover to limit the rotation angle of the roller core.

[0014] In the impurity removal structure described above, the limiting block is elongated and disposed on the roller core along the axial direction of the roller core.

[0015] As described above, the material used to make the limiting block in the impurity removal structure includes an elastic material.

[0016] The impurity removal structure described above,

[0017] The adhesive layer includes a first adhesive layer and a second adhesive layer;

[0018] Along the radial cross section of the roller core, the first adhesive layer and the second adhesive layer are respectively disposed on both sides of the limiting block.

[0019] As described above, in the impurity removal structure, both the first adhesive layer and the second adhesive layer are provided with a plurality of second filament structures. The extension lines of the second filament structures are tangent to the roller core diameter and point away from the roller core along the direction of the limiting block.

[0020] In the impurity removal structure described above, the distance between the end of the fixing cover away from the roller core fixing seat and the roller core or the adhesive layer is D, the length of the limiting block protruding from the outer surface of the roller core is d, and the shortest distance between the fixing cover and the adhesive layer is L. The relationship between D, d and L satisfies: D≥d>L.

[0021] The second technical solution adopted by this utility model to solve its technical problem is:

[0022] An air purifier, comprising:

[0023] shell;

[0024] An air outlet is located on the outer casing;

[0025] An air inlet is located on the outer casing;

[0026] A fan, which is located inside the housing, is used to drive air from the air inlet to the air outlet;

[0027] A filter element is disposed between the air inlet and the fan to filter the air entering the housing from the air inlet. The side of the filter element adjacent to the air inlet is the impurity accumulation surface.

[0028] The impurity removal structure described above is located between the filter element and the air inlet.

[0029] A transmission structure is provided between the air inlet and the filter element. The transmission structure is fixed to the outer shell. The movable end of the transmission structure is connected to the roller core fixing seat to drive the impurity removal structure to move back and forth on the impurity accumulation surface.

[0030] The beneficial effects of this utility model are:

[0031] 1. This application discloses an impurity removal structure, in which an adhesion layer for adhering contaminants on the filter element is provided on the outer surface of the roller core, the roller core fixing seat is rotatably connected to the two ends of the roller core along the axial direction, and a fixing cover is provided on both sides of the roller core along the radial direction of the roller core. The fixing cover, the roller core and the roller core fixing seat form a receiving cavity for accommodating contaminants. In use, the adhesion layer adheres to the surface of the filter element to be cleaned, the roller core fixing seat is pushed, the roller core rotates, and the adhesion layer adheres to the contaminants on the filter element. As the roller core fixing seat is pushed in the same direction, the adhering contaminants are rotated into the receiving cavity with the adhesion layer. The cleaned part of the filter element is clean and free of contaminant deposits, the filtration efficiency is improved, and the frequency of filter element replacement or cleaning can be reduced.

[0032] 2. This application also discloses an air purifier that uses a transmission structure to drive a removal structure to move back and forth on the impurity accumulation surface to remove pollutants from the impurity accumulation surface of the filter element, thereby improving the working efficiency of the air purifier and reducing its energy consumption.

[0048] Reference Figure 1 A filter removal structure 4 includes: a roller core 41 and a roller core fixing seat 43. The outer surface of the roller core 41 is provided with an adhesion layer 42, which is used to adhere contaminants on the filter element. The roller core fixing seat 43 is arranged adjacent to the roller core 41 along the radial direction of the roller core 41, and is rotatably connected to the roller core 41 at both ends along the axial direction of the roller core 41. The roller core fixing seat 43 includes fixing covers 431 arranged on both sides of the roller core 41 along the radial direction of the roller core 41. The side of the fixing cover 431 close to the roller core 41 is a first surface 4311. The fixing covers 431, the roller core 41, and the roller core fixing seat 43 enclose a receiving cavity 40 for accommodating contaminants. Rotating the roller core 41 allows the contaminants adhered by the adhesion layer 42 to be collected and accumulated in the receiving cavity 40.

[0049] Reference Figure 1 To illustrate the usage of the impurity removal structure 4 in this application, the roller core 41 is placed against the filter element 3, so that the adhesion layer 42 adheres to the surface of the filter element 3 to be cleaned. The roller core fixing seat 43 is pushed in direction A. Since the roller core fixing seat 43 is rotatably connected to the two ends of the roller core 41 in the axial direction, the roller core 41 and the adhesion layer 42 rotate synchronously. The adhesion layer 42 sticks to the contaminants of the filter element 3. The roller core fixing seat 43 is pushed in direction A. The adhered contaminants are rotated into the receiving cavity 40 along with the adhesion layer 42, so that the part of the filter element 3 to be cleaned is clean and there is no contaminant deposition. The filtration efficiency is improved, and the frequency of filter element replacement or cleaning can be reduced.

[0050] In a preferred embodiment of this invention, the impurity removal structure 4 can be applied to a pet air purifier. Over time, the filter element of a pet air purifier easily accumulates pet hair and dust on its surface. This pet hair can clog the air inlet holes on the filter element surface, reducing the filtration capacity of the air purifier, requiring users to frequently clean the hair from the filter element surface. The following description will use the impurity removal structure 4 in a pet air purifier as an example.

[0051] Understandably, when the impurity removal structure 4 is applied to a pet air purifier, pet hair accumulates on the surface of the filter element 3. When the roller core fixing seat 43 is pushed in direction A, the adhesive layer 42 sticks to the pet hair and brings the hair into the receiving cavity 40. The pet hair is in a loose state in the receiving cavity 40, and some of it is in contact with the inner wall of the receiving cavity 40. As the roller core fixing seat 43 is continuously pushed, the adhesive layer 42 comes into contact with the first surface 4311 through friction, scraping off the pet hair adhering to the adhesive layer 42 to clean the filter element 3.

[0052] Reference Figure 1 Furthermore, the material used to make the adhesive layer 42 includes lint-adhesive cloth. When the roller core 41 is rotated, the lint-adhesive cloth rubs against the first surface 431 so that the adhered hair accumulates in the receiving cavity 40.

[0053] Lint wicking cloths are specially designed for catching pet hair, and are especially suitable for use in pet air purifiers. They can catch a large amount of pet hair at once, improving cleaning efficiency.

[0054] Reference Figures 1 to 4 Furthermore, the fixing cover 431 also includes a scraping layer 4312 disposed on the first surface 4311, the scraping layer 4312 being provided with a plurality of first filamentous structures, the first filamentous structures being arranged in the direction of the receiving cavity 40.

[0055] It is understood that the roller core 41 is provided with a fixing cover 431 on both sides, and each first surface 4311 is provided with a scraping layer 4312. The scraping layers 4312 on both sides are respectively named the first scraping layer 4312-1 and the second scraping layer 4312-2. The working principle of this embodiment is illustrated below: When the roller core 41 rotates clockwise, the adhesion layer 42, together with the hair it adheres to, enters the receiving cavity 40 along the direction of the first filamentous structure of the first scraping layer 4312-1. When the roller core 41 rotates in the opposite direction, the roller core... The rotation direction of roller core 41 is opposite to the direction of the first filamentous structure. The first scraping layer 4312-1 scrapes the hair in the adhesive layer 42 into the receiving cavity 40, thereby cleaning the pet hair on the scraping layer 4312. Similarly, when roller core 41 rotates counterclockwise, the adhesive layer 42 and the hair it adheres to enter the receiving cavity 40 along the direction of the first filamentous structure of the second scraping layer 4312-2. When roller core 41 rotates in the opposite direction, the second scraping layer 4312-2 scrapes the hair in the adhesive layer 42 into the receiving cavity 40.

[0056] The scraping layer 4312 with a first filamentous structure can improve the cleaning degree of the adhesion layer 42, thereby increasing the amount of pet hair stuck to the filter element 3 by the adhesion layer 42 and improving the cleaning effect of the filter element 3; the first filamentous structure is arranged in the direction of the receiving cavity 40 to scrape the pet hair off the adhesion layer 42, which is a means to improve the cleaning degree of the adhesion layer 42.

[0057] As a preferred embodiment, the roller core 21 is cross-sectioned radially, and the roller core fixing seat 43 and the fixing cover 431 surround at least 1 / 2 of the outer periphery of the roller core 41, providing sufficient space to guide the hair of the scraping layer 4312 into the receiving cavity 40.

[0058] In one embodiment, a limiting block 45 is provided on the outer surface of the roller core 41. The limiting block 45 is used to abut against the fixing cover 431 to limit the rotation angle of the roller core 41 and fix the relative position of the adhesive layer 42 and the filter element 3.

[0059] It is understandable that when the roller core fixing seat 43 is pushed in the direction A, the roller core 41 rotates counterclockwise, the limiting block 45 abuts against the fixing cover 431 on one side, and the roller core fixing seat 43 is pushed in the direction A continuously. The relative position of the roller core 41 and the roller core fixing seat 43 remains unchanged. When hair is attached to the first surface 4311, it accumulates at the angle between the adhesive layer 42 and the filter element 3. When the roller core fixing seat 43 is pushed in the direction B (the direction B is opposite to A), the roller core 41 rotates clockwise, and the adhesive layer 42 with attached hair enters the receiving cavity 40. Then the roller core fixing seat 43 is pushed in the direction A again, and the first scraping layer 4312-1 scrapes the hair on the adhesive layer 42.

[0060] In one embodiment, the limiting block 45 is elongated and is disposed on the roller core 41 along the axial direction of the roller core 41.

[0061] The elongated limiting block 45 has more contact points with the fixing cover 431, and the limiting block 45 fixes the relative position of the roller core 41 and the roller core fixing seat 43 better.

[0062] In one embodiment, the limiting block 45 is made of an elastic material. When the limiting block 45 comes into contact with the fixing cover 431, the limiting block 45 deforms and absorbs some energy, thereby reducing the damage caused by the collision between the limiting block 45 and the fixing cover 431 to the entire impurity removal structure 4, and avoiding deformation of the components in the impurity removal structure 4, which would affect the impurity removal effect.

[0063] Reference Figures 1 to 4 In one embodiment, the adhesive layer 42 includes a first adhesive layer 421 and a second adhesive layer 422;

[0064] Along the radial cross section of the roller core 41, the first adhesive layer 421 and the second adhesive layer 422 are respectively disposed on both sides of the limiting block 45.

[0065] Understandably, when the roller core holder 43 is pushed in direction A, the roller core 41 rotates counterclockwise by approximately 130 degrees, and the second adhesive layer 422 enters the receiving cavity 40 or becomes adjacent to the second scraping layer 4312-2. As the roller core holder 43 is continuously pushed in direction A, the relative positions of the roller core 41 and the roller core holder 43 remain unchanged. Hair adhering to the first surface 4311 accumulates at the angle between the first adhesive layer 421 and the filter element 3. When the roller core holder 43 is pushed in direction B, the roller core 41 rotates clockwise, and the second adhesive layer 422 abuts against the first surface 4311. The first adhesive layer 421 of the adhering hair then enters the receiving cavity 40. If hair remains on the first surface 4311, as the roller core fixing seat 43 moves, the remaining hair will accumulate between the second adhesion layer 422 and the filter element 3. The roller core fixing seat 43 is rotated in the opposite direction to push the roller core fixing seat 43. The hair stuck on the first adhesion layer 421 is scraped off by the first scraping layer 4312-1 into the receiving cavity 40. The above operation is repeated. The hair stuck on the second adhesion layer 422 is scraped off by the second scraping layer 4312-2 into the receiving cavity 40. The above steps are repeated to clean the first surface 431. The operation steps are simple, and since the roller core 41 cleans the adhesion layer 42 once every time it moves one end, the cleaning effect of the filter element 3 is better.

[0066] In one embodiment, both the first adhesive layer 421 and the second adhesive layer 422 are provided with a plurality of second filamentous structures. The extension line of the second filamentous structure is tangent to the roller diameter of the roller core 41 and points away from the roller core 41 along the direction of the limiting block 45. The direction of the second filamentous structure is that it accumulates at the angle between the adhesive layer 42 and the filter element 3. Therefore, when the roller core 1 rotates, it can carry more hair and roll it into the receiving cavity 40, further improving the cleaning effect on the filter element 3.

[0067] Reference Figure 2 In one embodiment, the distance between the end of the fixing cover 431 away from the roller core fixing seat 43 and the roller core 41 or the adhesive layer 42 is D, the length of the limiting block 45 protruding from the outer surface of the roller core 41 is d, and the shortest distance between the fixing cover 431 and the adhesive layer 42 is L. The relationship between D, d and L satisfies: D≥d>L, which can ensure that the limiting block 45 will not enter the receiving cavity 40 and affect the relative positional relationship between the limiting block 45 fixing the roller core 41 and the filter element 3.

[0068] Reference Figures 5 to 6As a preferred embodiment, the above-described impurity removal structure 4 can be applied to an air purifier, which includes: a housing 1; an air outlet 11 disposed on the housing 1; an air inlet 12 disposed on the housing 1; a fan 2 disposed inside the housing 1 to drive air from the air inlet 12 to the air outlet 11; and a filter element 3 disposed between the air inlet 12 and the fan 2 to filter the air entering the housing 1 from the air inlet 12, wherein the side of the filter element 3 adjacent to the air inlet 12 is an impurity accumulation surface 31; the impurity removal structure 4 as described in any of the above embodiments is disposed between the filter element 3 and the air inlet 12.

[0069] The transmission structure 5 is located between the air inlet 12 and the filter element 3. The transmission structure 5 is fixed to the outer shell 1. The movable end of the transmission structure 5 is connected to the roller core fixing seat 43 to drive the impurity removal structure 4 to reciprocate on the impurity accumulation surface 31.

[0070] The transmission structure 5 replaces manual labor with mechanical transmission, realizing fully automatic cleaning of hair attached to the filter element 3 and improving the user experience.

[0071] In a preferred embodiment, the transmission structure 5 includes a left lead screw 51, a right lead screw 52, ​​a left lead screw nut, a right lead screw nut 54, and a drive motor 55;

[0072] The left lead screw 51 and the right lead screw 52 are arranged parallel to each other. The two ends of the left lead screw 51 are rotatably connected to the outer casing 1. One end of the right lead screw 52 is rotatably connected to the outer casing 1, and the other end is connected to the drive end of the drive motor 55. The left lead screw nut is threadedly connected to the left lead screw 51 and the right lead screw 52. Along the radial direction of the roller core 41, the left lead screw nut and the right lead screw nut 54 are respectively connected to the roller core fixing seat 43.

[0073] The drive motor 55 drives the lead screw 52 to rotate, thereby causing the left lead screw nut to move axially along the left lead screw 51 and the right lead screw nut 54 to move axially along the right lead screw 52, ​​so as to drive the impurity removal structure 4 to remove the impurities accumulated on the impurity accumulation surface 31.

[0074] Of course, the left lead screw 51 can also be replaced with a guide rail, and the left lead screw nut can be replaced with a slider.

[0075] Specifically, the transmission structure 5 can also be a belt drive structure.
