DETAILED DESCRIPTION

[0032] An indoor air purifier, reference Figures 1 to 6, including a purifier shell for adsorbing pet hair, the purifier shell includes: a first air-permeable wall 2 located at the bottom, and a connecting shell fixedly connected to the upper end of the first air-permeable wall 2, and a second air-permeable wall 6 fixedly connected to the upper end of the connecting shell. Among them, the height of the first air-permeable wall 2 itself is preferably 30cm to 60cm, and the height of the second air-permeable wall 6 from the ground is preferably 150cm to 180cm. The first air-permeable wall 2 and the second air-permeable wall 6 serve as air intake structures, and the connecting shell is a closed structure that cannot intake air, thereby forming an air intake height difference. The outer wall surface of the first air-permeable wall 2 and the second air-permeable wall 6 is a cylindrical surface or a square wall surface, and is evenly distributed with holes, preferably a cylindrical surface. An outer filter layer 17 is fixedly connected to the outer wall of the first air-permeable wall 2 and the second air-permeable wall 6. The outer filter layer 17 is preferably a low-cost and repeatedly washable non-woven fabric or nylon mesh, which is used to intercept pet hair. The height of the connecting shell is relatively inefficient for the adsorption of pet hair, so it is used as a closed structure to increase the air flow of the first air-permeable wall 2 and the second air-permeable wall 6, thereby increasing the suction force in disguise. The height of the first air-permeable wall 2 is close to the indoor floor and is at the height of the floor, sofa and bed, which is a height for efficient adsorption of pet hair. On the other hand, the height of the second air-permeable wall 6 mainly involves the height range of the nasal cavity after a person sits on a sofa, bed or stands, thereby adsorbing pet hair in this height range.

[0033] A longitudinal air passage is formed inside the first air-permeable wall 2, the connecting shell and the second air-permeable wall 6. A top wall 7 is fixedly connected to the upper end of the second air-permeable wall 6. An inner filter layer 9 is detachably connected to the top wall 7. The filter layer 9 can adopt a primary-efficiency, medium-efficiency or high-efficiency filter structure according to needs. A first air pump 10 located above the filter layer is fixedly connected to the top wall 7, so that a longitudinal airflow from bottom to top is generated, thereby generating suction on the outer wall surfaces of the first air-permeable wall 2 and the second air-permeable wall 6.

[0034] In order to increase the pet hair collection effect, it also includes a half shell used in conjunction with the first air-permeable wall 2 and the second air-permeable wall 6, taking the case where the first air-permeable wall 2 and the second air-permeable wall 6 are cylindrical surfaces as an example;

[0035] Combination Fig.11The half shell includes shielding leaves 19 arranged in a longitudinal array. The shielding leaves 19 are semicircular ring structures. The upper and lower end surfaces of the shielding leaves 19 are inclined surfaces that are flat and inclined to each other. For example, the upper end surface of the shielding leaves 19 close to the purifier shell gradually decreases or increases, preferably increases, so that an oblique opening is formed between any two adjacent shielding leaves 19. On the other hand, the half shell also includes connecting ribs 19 fixed to all the shielding leaves 19. The number of connecting ribs 19 is at least two, and they are respectively placed at the two vertical ends of the shielding leaves 19; the bottom of the connecting ribs 19 is lower than the lowest shielding leaf 19. The two half shells are a set of covers that are buckled together to form a complete cylindrical wall body. The connecting ribs 19 of the two half shells fit each other and are temporarily fixed by buckle or magnetic attraction, preferably magnetic attraction. Thereby, the first air-permeable wall 2 is surrounded by two half shells, and the second air-permeable wall 6 is also surrounded by two half shells. At the same time, there is a spacing of 0.5 cm to 1.5 cm between the first air-permeable wall 2 and the second air-permeable wall 6 and their respective half shells to form two accommodating cavities respectively located on the upper and lower sides of the connecting shell. When the pet hair passes through the oblique mouth and is sucked on the outer filter layer 17, as the amount of pet hair gradually increases, a thin cloth-like structure will spontaneously form and be stored in the accommodating cavity. The inclined shielding leaves 19 are conducive to the entry of pet hair, and also to the accumulation of pet hair, so that the pet hair has a supporting surface formed by longitudinally distributed prisms.

[0036] In order to facilitate the gathering of pet hair, a detachable connection seat 5 is provided at the lower end of the first air-permeable wall 2. The outer peripheral wall surface of the connection seat 5 is a chamfered surface with a diameter decreasing from bottom to top, so that the suction force of pet hair on the ground directly moves upward along the outer peripheral surface of the connection seat 5 into the lower accommodation cavity. A slot 1-1 for the connection rib 19 to be inserted is provided on the outer peripheral wall surface of the connection seat 5. When the lower half shell needs to be removed, it is only necessary to lift the half shell upward to disengage the connection rib 19 from the slot 1-1, and then separate the two fixed half shells.

[0037] To further illustrate, the connecting shell includes a first connecting wall 3, and a second connecting wall 4 fixedly connected to the upper end of the first connecting wall 3, the first connecting wall 3 is fixedly connected to the upper end of the first air-permeable wall 2, the circumference of the first connecting wall 3 increases from bottom to top, the circumference of the second connecting wall 4 decreases from bottom to top, the bottom peripheral edge of the outer wall surface of the first connecting wall 3 does not protrude beyond the top peripheral edge of the first air-permeable wall 2, and the top periphery of the second connecting wall 4 does not protrude beyond the bottom peripheral edge of the second air-permeable wall 6, so that after the pet hair contacts the connecting shell due to suction, it will directly enter the two accommodating chambers along the inclined surface of the connecting shell.

[0038] Preferably, a sink groove 1-2 is provided at the lower end of the base 1, and the second connecting wall 4 is detachably connected to the base 1 by screws, and the screws are located in the sink groove 1-2.

[0039] Preferably, a first annular support member 7-1 is fixedly connected to the inner wall of the top wall 7, a connecting member 8 is placed on the first supporting member 7-1, the inner filter layer 9 is fixedly connected to the connecting member 8, an annular outlet is provided on the wall surface of the top wall 7, the connecting member 8 is located in the annular outlet, and the connecting member 8 can enter and exit the top wall 7 through the annular outlet, and a socket 8-1 located in the annular outlet is provided on the connecting member 8 for a finger to enter and hook the inner filter layer 9.

[0040] Preferably, the upper end of the top wall 7 is fixedly connected with a ventilating cover 11 located above the first air extractor 10. There is a distance between the top of the ventilating cover 11 and the indoor roof. When installing, a telescopic rod is preferably used to abut between the ventilating cover 11 and the roof to fix the position of the indoor air purifier. The telescopic rod can be a two-section rod connected by threaded fittings, and the distance between the two rods can be adjusted by rotating the rod.

[0041] To increase indoor ventilation speed, or enhance the effect of opening windows, reduce turbulence and continuously absorb pet hair, combined with Figures 7 to 10 A third support member 7-3 with an annular groove is fixedly connected to the outer wall of the top wall 7, a ring platform 12-1 is inserted in the third support member 7-3, a first guide plate 12 which is not higher than the top wall 7 is fixedly connected to the upper end of the ring platform 12-1, a connecting column 13 is fixedly connected to the upper end of the first guide plate 12, a second guide plate 14 is fixedly connected to the upper end of the connecting column 13, a horizontal air duct is formed between the first guide plate 12 and the second guide plate 14, so that the filtered air goes on the roof, forming a circulating wind that flows down the wall back to the ground, promoting the pet hair on the ground to flow close to the first air permeable wall 2 and the second air permeable wall 6.

[0042] Preferably, an electric telescopic mechanism 15 is fixedly connected to the top wall 7 or the first guide plate 12, and a shield 16 is fixedly connected to the telescopic end of the electric telescopic mechanism 15. The electric telescopic mechanism 15 is used to drive the shield 16 to rise and fall. The shield 16 is used to shield one side of the horizontal air duct. When installed, the shield 16 is directed to one side of the window to prevent convection between the window intake and the indoor air purifier exhaust. At this time, the telescopic rod should be installed between the second guide plate 14 and the roof.

[0043] The indoor air purifier of this application can be installed between the kitchen and the living room in an integrated kitchen layout, or near the wall or door near the end of the master bed. It will be more effective if used with a skirting exhaust fan. The skirting exhaust fan is suitable for placement under the sofa, bed or the skirting at the bottom of the wall. Fig.12The skirting exhaust fan includes a rectangular shell 20, an air outlet is arranged on the vertical end face of the long side of the shell 20, and the air outlet faces the indoor air purifier. An air inlet is arranged on the vertical end face of the wide side of the shell 20. A second exhaust fan 21 is fixedly connected in the shell 20 to generate thrust on the vertical end face of the long side of the shell 20. The second exhaust fan 21 draws air from the air inlet to make the airflow of the air outlet hit the indoor air purifier. A sponge can be added to the top of the shell 20 to rest against the bottom plate of the bed or the bottom plate of the sofa.
