Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and more specifically, it relates to a deodorizing and sterilizing device for cat litter boxes. Background Technology

[0002] Cats are naturally sensitive and have high requirements for their defecation environment, which has driven the rise of the litter box industry. However, the entrances of existing litter boxes generally lack a sealed structure, resulting in insufficient privacy and easy leakage of pungent odors. At the same time, cat feces easily breed a large number of bacteria, which in turn pollutes indoor air and has a significant impact on the overall home environment.

[0003] Most deodorizing and sterilizing devices currently on the market target bacteria in the air, which limits their functionality. They cannot directly act on the surface and interior of the litter box, nor can they effectively sterilize and disinfect the litter box itself, leaving potential hygiene hazards unresolved.

[0004] Furthermore, when using a litter box, cats often knock litter out of the box when entering or leaving, causing litter to scatter on the floor. This not only affects the cleanliness and aesthetics of the room but also makes daily cleaning inconvenient and poses a challenge to the overall maintenance of the indoor environment.

[0005] In view of this, we propose a deodorizing and sterilizing device for cat litter boxes. Utility Model Content

Detailed Implementation

[0023] Please see Figures 1-6A deodorizing and sterilizing device for cat litter boxes includes a base 1, two legs 2 fixedly connected to the base 1, a fixed shell 3 fixedly connected to the legs 2, an air duct in the middle of the fixed shell 3, a fan 4 fixedly connected to the top of the fixed shell 3, an ionization sterilization module 5 fixedly installed in the air duct of the fixed shell 3, a filter plate 6 fixedly connected to the bottom of the fixed shell 3, ultraviolet lamps 7 fixedly connected to both legs 2, an annular shielding cloth 8 fixedly connected to the outside of the fixed shell 3, a sliding frame 9 fixedly connected to the lower side of the annular shielding cloth 8, the sliding frame 9 being slidably connected to the two legs 2, the base 1 having a cleaning structure and a fixing structure; a winding wheel 10 fixedly connected to both sides of the fixed shell 3, a pull rope 11 fixedly connected between the winding wheel 10 and the sliding frame 9; a motor 12 fixedly connected to both sides of the fixed shell 3, the output shaft of the motor 12 being fixedly connected to the adjacent winding wheel 10; the base 1 having a cavity structure, a support mesh plate 13 fixedly connected to the base 1, and a through groove on one side of the base 1.

[0024] Working principle: Place the litter box on the support mesh plate 13, and then turn on the fan 4. The fan 4 draws the air from the litter box into the air duct of the fixed shell 3. The air passes through the filter plate 6 and the ionization sterilization module 5 in sequence. The filter plate 6 filters the dust in the air, and the ionization sterilization module 5 purifies the odor emitted by the litter box and sterilizes it at the same time.

[0025] When the litter box needs to be sterilized, the two motors 12 are activated. The motors 12 drive the winding wheel 10 to rotate, and the winding wheel 10 releases the pull rope 11. Under the gravity of the sliding frame 9, the sliding frame 9 moves downward along the two support legs 2 until the support legs 2 contact the upper side of the base 1. Then, the two ultraviolet lamps 7 are activated, and the ultraviolet lamps 7 irradiate the litter box for sterilization. At this time, the ring-shaped shielding cloth 8 blocks the light of the ultraviolet lamps 7 to prevent the light of the ultraviolet lamps 7 from scattering outward, which improves the safety of the device.

[0026] After sterilization is completed, the two ultraviolet lamps 7 are turned off, the two motors 12 are restarted, the winding wheel 10 winds up the pull rope 11, thereby moving the sliding frame 9 upward to reset, and the annular shielding cloth 8 is reset to its initial state.

[0027] Please see Figure 4 and Figure 5 The cleaning structure includes two guide shafts 14, both of which are fixedly connected to the cavity of the base 1. The two guide shafts 14 are slidably connected to a scraper 15, which abuts against the base 1. The base 1 is rotatably connected to two pulleys 16, and a synchronous belt 17 is wound between the two pulleys 16. The synchronous belt 17 is fixedly connected to the scraper 15. A second motor 18 is fixedly connected to the base 1, and the output shaft of the second motor 18 is fixedly connected to the adjacent pulley 16.

[0028] Working principle: As the cat enters and exits the litter box, the litter it carries falls onto the support mesh plate 13 and enters the cavity of the base 1 through the support mesh plate 13. After a period of time, the second motor 18 is started. The output shaft of the second motor 18 drives the pulley 16 on the lower side to rotate, causing the synchronous belt 17 to move around the two pulleys 16. The synchronous belt 17 drives the scraper 15 to slide along the two guide shafts 14. The scraper 15 pushes the litter in the base 1, pushing the litter to one side of the base 1 and discharging it from the through groove on one side of the base 1, thereby preventing the litter from scattering on the ground and causing circular pollution in the room.

[0029] Please see Figure 1 and Figure 6 The fixed structure includes two support plates 19, which are respectively fixed to two legs 2. The support plates 19 are slidably connected to sliding rods 20, and the sliding rods 20 are fixedly connected to pressing plates 21. A spring 22 is fixedly connected between the pressing plates 21 and the support plates 19.

[0030] Working principle: When placing the cat litter on the support mesh plate 13, first pull the sliding rods 20 on both sides. The sliding rods 20 slide along the support plate 19, and the spring 22 is compressed. After the cat litter box is placed, release the sliding rods 20. Under the elastic force of the spring 22, the two extrusion plates 21 extrude the cat litter box, thereby improving the stability of the cat litter box on the support mesh plate 13.

[0031] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
