[0002] Pet air purifiers are a sub-category of household appliances that have emerged in recent years with the rapid increase in pet-owning families and the upgrading of health needs. As pets gradually become important members of the family, problems such as hair, dandruff, allergens, and odors they bring have become increasingly prominent, and traditional air purifiers are difficult to specifically solve these compound pollutions.

[0003] Chinese Patent No. CN118776000A discloses a pet air purifier with a pet hair collection and treatment system based on airflow control. A strong airflow is generated by a duct turbine unit to inhale the external airflow containing pet floating hair and dandruff, and it is filtered by a primary filter inside the housing; the pet floating hair and dandruff are filtered by the primary filter group to the air-blowing side of the filter; a blower is arranged on the side of the housing of the primary filter to blow the pet hair on the filter into the collection box.

[0004] The above air purifier uses two blowers, namely a duct turbine and a side blower, to realize pet hair collection, resulting in complex control and high cost. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems existing in the prior art and propose an air purifier for collecting pet hair.

[0006] The purpose of the present invention can be achieved by the following technical solutions: An air purifier for collecting pet hair, comprising:

[0007] An outer housing, an air inlet is provided on the side of the outer housing, and a receiving groove is provided adjacent to the air inlet;

[0008] A hair collection box, the hair collection box is arranged in the receiving groove, and a first inlet is provided on the side of the hair collection box close to the inside of the air purifier;

[0009] An air inlet channel, the air inlet channel is arranged inside the outer housing, and the air inlet channel is respectively communicated with the air inlet and the first inlet;

[0010] Wherein, the side wall of the air inlet channel at least forms part of the receiving groove. When the air purifier is working, pet hair sequentially enters the hair collection box through the air inlet, the air inlet channel, and the first inlet.

[0011] As a further improvement of the present invention, the hair collecting box includes a hair collecting channel and a receiving space. The hair collecting channel and the receiving space are separated by a partition wall. The two ends of the hair collecting channel are a first inlet and a second inlet respectively, and the second inlet is communicated with the receiving space.

[0012] As a further improvement of the present invention, the channel diameter of the hair collecting channel gradually decreases along the direction from the first inlet to the second inlet, and the partition wall is integrally formed with the side wall of the hair collecting box.

[0013] As a further improvement of the present invention, the diameter of the air inlet channel gradually decreases along the direction from the air inlet to the first inlet, and a downward depression is provided at the adjacent position of the air inlet channel and the first inlet.

[0014] As a further improvement of the present invention, it further includes a middle frame and an inner housing. The outer housing includes an upper housing and a lower housing. The middle frame is arranged on the lower housing, the inner housing is arranged on the middle frame, and the upper housing is detachably connected to the inner housing.

[0015] As a further improvement of the present invention, it further includes a filter element and a power device. The filter element and the power device are sequentially arranged above the air inlet channel, and the filter element is arranged in the installation space surrounded by the middle frame and the inner housing.

[0016] As a further improvement of the present invention, the power device includes a volute and a wind wheel arranged in the volute. The volute is arranged on the top of the inner housing.

[0019] As a further improvement of the present invention, it further includes a sensor system and a power device. The sensor system is used to detect the weight of the air purifier. When the weight of the air purifier reaches a first threshold, the power device will switch to a higher speed. When the weight of the air purifier reaches a second threshold, and the second threshold is greater than the first threshold, the power device stops working.

[0020] Based on the above technical solution, the present invention can at least achieve the following technical effects:

[0021] 1. By optimizing the design of the air inlet channel, pet hairs will be collected in the hair collection box during the air intake process of the air purifier;

[0022] 2. The hair collection box is divided into a hair collection channel and a receiving space by a partition wall, so that the pet hairs entering the receiving space will not be sucked back into the air inlet channel;

[0023] 3. Since the flow rate of the fluid increases and the pressure decreases when passing through a narrowed channel, by setting the diameter of the hair collection channel to gradually decrease from the first inlet to the second inlet, the pet hairs will be concentrated towards the second inlet through the hair collection channel;

[0024] 4. By setting the diameter of the air inlet channel to gradually decrease from the air inlet to the first inlet, the pet hairs will be concentrated towards the first inlet through the air inlet channel;

[0025] 5. By providing a recess adjacent to the first inlet in the air inlet channel, the pet hairs are easily collected at the recess and enter the first inlet;

[0026] 6. By providing a storage box on the upper housing, the purifier is provided with additional storage space, which can be used to place pet food, cleaning items, etc.;

[0027] 7. By providing a tray on the top of the outer housing, the pet can rest on the tray, and a heating element is provided on the tray for heating the pet carpet;

[0028] 8. When the air purifier has collected a part of the hairs, the filter element surface will have hairs and impurities adsorbed, which will affect the air output. By providing a sensor system, when it is detected that the weight of the air purifier reaches the first threshold, the wind wheel switches to a high rotation speed to compensate for the air output.

[0036] The following are specific embodiments of the present invention, and in combination with the attached Figures 1-5 , the technical solutions of the present invention are further described, but the present invention is not limited to the following embodiments.

[0037] An air purifier for collecting pet hair, which is used to collect impurities such as particulate matter and pet hair around the air purifier, includes: a housing and a hair collecting box 200. An air inlet 110 is provided on the side surface of the housing, and a receiving groove 120 is provided adjacent to the air inlet 110. The hair collecting box 200 is arranged in the receiving groove 120, and the outer contour of the hair collecting box 200 is adapted to the size of the receiving groove 120. A first inlet 211 is provided on one side of the hair collecting box 200 close to the inside of the air purifier. An air inlet passage 130 is arranged in the housing, and the air inlet passage 130 is respectively communicated with the air inlet 110 and the first inlet 211. The side wall of the air inlet passage 130 at least partially constitutes the receiving groove 120. When the air purifier works, pet hair enters the hair collecting box 200 successively through the air inlet 110, the air inlet passage 130 and the first inlet 211.

[0038] It should be noted that the side surface of the housing refers to other surfaces except the top surface and the bottom surface of the housing. The side of the hair collecting box 200 close to the inside of the air purifier refers to the side of the hair collecting box 200 away from the surface of the air purifier when it is in the installed position. In this embodiment, the air inlet passage 130 extends in a curved manner in the clockwise direction and includes a first side wall 131 and a second side wall 132. The first side wall 131 is set as an arc surface and at least partially constitutes the receiving groove 120, and the second side wall 132 has a connected flat section and an arc section. The first side wall 131 adopts an involute arc surface design, and cooperates with the flat and arc composite structure of the second side wall 132 to form a spiral air flow acceleration effect. By optimizing the design of the air inlet passage 130, pet hair will be gathered into the hair collecting box 200 during the air inlet process of the air purifier.

[0039] The hair collecting box 200 includes a hair collecting passage 210 and a receiving space 220. The hair collecting passage 210 and the receiving space 220 are separated by a partition wall 230. The two ends of the hair collecting passage 210 are respectively a first inlet 211 and a second inlet 212, and the second inlet 212 is communicated with the receiving space 220. In this embodiment, the hair collecting box 200 is slidably connected to the receiving groove 120. When the pet hair in the hair collecting box 200 is full, the user can pull out the hair collecting box 200 from the receiving groove 120 for cleaning. By separating the hair collecting box 200 into the hair collecting passage 210 and the receiving space 220 through the partition wall 230, the pet hair entering the receiving space 220 will not be sucked back into the air inlet passage 130.

[0040] Preferably, the channel diameter of the hair collecting passage 210 gradually decreases along the direction from the first inlet 211 to the second inlet 212. Since the flow velocity of the fluid increases and the pressure decreases when passing through a narrowed channel, by setting the diameter of the hair collecting passage 210 to gradually decrease along the direction from the first inlet 211 to the second inlet 212, the pet hair is concentrated towards the second inlet 212 through the hair collecting passage 210.

[0041] Preferably, in this embodiment, the partition wall 230 and the side wall of the hair collecting box 200 are integrally provided.

[0042] Preferably, the caliber of the air inlet passage 130 gradually decreases along the direction from the air inlet 110 to the first inlet 211. By setting the caliber of the air inlet passage 130 to gradually decrease along the direction from the air inlet 110 to the first inlet 211, pet hair is concentrated towards the first inlet 211 through the air inlet passage 130.

[0043] A downward depression 133 is provided at the adjacent position of the air inlet passage 130 and the first inlet 211. In this embodiment, at the adjacent position to the first inlet 211, the width of the depression 133 is equivalent to the width of the first inlet 211, and along the direction away from the first inlet 211, the width of the depression 133 gradually decreases slightly. By providing the depression 133 at the adjacent position of the air inlet passage 130 and the first inlet 211, it is easy for pet hair to gather at the depression 133 and enter the first inlet 211.

[0044] Specifically, the air purifier for collecting pet hair of the present invention further includes a middle frame 300 and an inner housing 400.

By arranging the filter element 800 in the installation space surrounded by the middle frame 300 and the inner housing 400, the filter element 800 is firmly installed, and when a pet plays on the air purifier, the filter element 800 will not fall off.

[0047] The power device includes a volute 600 and a wind wheel 700 disposed in the volute 600. The wind wheel 700 is driven by a motor disposed in the wind wheel 700 (not shown in the figure). The volute 600 is disposed at the top of the inner housing 400. An air vent grille 410 is provided at the top of the inner housing 400. The air inlet passage 130 communicates with the volute 600 through the air vent grille 410. An air outlet 510 is provided on the side of the upper housing 500. The volute 600 communicates with the air outlet 510. The orientation of the air outlet 510 is different from that of the air inlet 110.

[0048] Preferably, a negative ion generator is provided on the air outlet 510, so that the air purifier can better purify the air, sterilize, and remove odors, further improving the air quality.

[0049] After the wind wheel 700 of the air purifier for collecting pet hair of the present invention operates, air enters from the air inlet 110, and then the air sequentially passes through the air inlet passage 130, the filter element 800, and the volute 600 and is discharged from the air outlet 510. In this embodiment, the orientation of the air outlet 510 is perpendicular to that of the air inlet 110. An air outlet grille is provided on the air outlet 510, and the air outlet grille can adjust the air outlet angle.

[0050] The air purifier for collecting pet hair of the present invention further includes a storage box 520. The storage box 520 is disposed on the upper housing 500 and is detachably connected to the middle frame 300. Specifically, a button 521 is provided on the surface of the storage box 520 facing the outside. A hook 522 is connected to the button 521. A card slot 310 is provided at the corresponding position of the middle frame 300. The hook 522 is engaged with the card slot 310. When the storage box 520 is disassembled, the button 521 is pressed, and the hook 522 is disengaged from the card slot 310, so that the storage box 520 is separated from the middle frame 300. By providing the detachable connection between the storage box 520 and the middle frame 300, the installation and disassembly of the storage box 520 are facilitated.

[0051] Preferably, a tray 900 is provided at the top of the outer housing of the air purifier for collecting pet hair of the present invention. A plurality of mounting posts are provided on the bottom surface of the tray 900. A plurality of mounting seats 420 are provided at the corresponding positions on the top surface of the inner housing 400. The mounting posts are inserted into the mounting seats 420. A heating element is provided on the tray 900. By providing the tray 900 at the top of the outer housing, a pet can rest on the tray 900, and a heating element is provided on the tray 900 for heating a pet mat.

[0052] The air purifier for collecting pet hair of the present invention further includes a sensor system for detecting the weight of the air purifier. In this embodiment, a load-bearing block 140 is provided at the bottom of the lower housing. A pressure sensor is provided in the load-bearing block 140. The weight of the air purifier can be calculated based on the pressure received by the load-bearing block 140.

[0053] When the weight of the air purifier reaches the first threshold, the impeller 700 will switch to a higher rotational speed. After the air purifier collects a part of the hair, there will be hair and impurities adsorbed on the surface of the filter element 800, which will affect the air output. By setting up a sensor system, when it is detected that the weight of the air purifier reaches the first threshold, the impeller 700 switches to a high rotational speed, thereby compensating for the air output.

[0054] When the weight of the air purifier reaches the second threshold, where the second threshold is greater than the first threshold, the impeller 700 stops working. When the weight of the air purifier reaches the second threshold, it indicates that there is too much hair and impurities in the air purifier and it needs to be cleaned. Therefore, the air purifier will automatically shut down to avoid overloading the air purifier.

[0055] The sensor system of the air purifier for collecting pet hair in the present invention is also used to detect the motion characteristic values of the air purifier such as displacement, speed, acceleration, etc. When it is detected that the motion characteristic values of the air purifier reach the threshold, the power supply of the air purifier is cut off. By detecting the motion characteristic values of the air purifier, when the user moves the air purifier or a pet collides with the air purifier, the power supply of the air purifier is cut off to protect the safety of the user and the pet and at the same time avoid damage to the air purifier.

[0056] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements or use similar methods to replace the described specific embodiments, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
