Description

Technical Field

[0001] This invention relates to the field of pet supplies technology, and more particularly to a deodorizing device and a cat litter box. Background Technology

[0002] To meet the needs of pet owners, the pet industry provides corresponding pet supplies based on the different biological characteristics of various pets. For example, cats have a strong biological instinct to require a suitable environment for defecation, needing to bury their excrement in litter to prevent predators from smelling it. Therefore, cat owners typically provide them with litter boxes, also known as cat toilets, filled with cat litter. After relieving themselves in the litter, the cat will paw at the litter to cover its waste. However, the odor from excrement lingers, affecting air quality and potentially leading to the growth of harmful bacteria. For existing cat toilets, especially those with rollers, achieving stable and comprehensive odor control within the toilet bowl, and ensuring continuous odor control even during the roller's rotation, is a pressing issue that needs to be addressed. Summary of the Invention

[0003] The purpose of this invention is to provide a deodorizing device and a cat litter box that achieves stable and comprehensive deodorization and improves air freshness.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A deodorizing device is installed in the mounting hole of the roller, wherein the deodorizing device includes:

[0006] The deodorizing component is rotatably disposed in the mounting hole. The deodorizing component includes a deodorizing liquid bottle, a long cotton core inserted into the deodorizing liquid bottle, a short cotton core overlapping the long cotton core, and a spray assembly. The spray assembly is connected to the short cotton core, and the short cotton core conveys the deodorizing liquid in the deodorizing liquid bottle to the spray assembly through the long cotton core. The spray assembly can spray the deodorizing liquid into the inside of the roller.

[0007] Alternatively, the spray assembly includes a nozzle and an atomizing plate, the nozzle being fitted over the outside of the short cotton core, and the atomizing plate being connected to the nozzle and capable of breaking the deodorizing liquid into liquid particles.

[0008] Optionally, it also includes a rotating chassis to which the deodorizing component is connected, and the rotating chassis is mounted in the mounting hole.

[0009] Optionally, the rotating chassis includes a rotating inner ring, a counterweight, and a rotating outer ring. The rotating outer ring is installed in the mounting hole, and the rotating inner ring is rotatably connected to the rotating outer ring. The counterweight is disposed on the rotating inner ring, and the deodorizing component is connected to the rotating inner ring. When the roller drives the rotating outer ring to rotate synchronously, the position of the rotating inner ring remains unchanged under the action of the counterweight.

[0010] Optionally, the deodorizing component is provided with a hanging part, and the rotating base is provided with a rotating hanging part connected to the rotating inner ring. The rotating hanging part is provided with a plug-in groove, and the hanging part can be inserted into the plug-in groove.

[0011] Optionally, the deodorizing component includes a back cover and a housing, with the hanger disposed on the outside of the back cover and the inside of the back cover and the housing forming an accommodating space, wherein the deodorizing liquid bottle, the long cotton wick, the short cotton wick and the spray assembly are all disposed in the accommodating space.

[0012] Alternatively, the housing may be provided with a spray nozzle, through which the spray assembly can spray the deodorizing liquid into the interior of the roller.

[0013] Optionally, the deodorizing component is provided with a light to identify its position within the roller.

[0014] Alternatively, the deodorizing component may include a battery for driving the spray assembly.

[0015] Cat litter box, including this deodorizing device.

[0016] The beneficial effects of this invention are:

[0017] This invention utilizes a deodorizing device to achieve real-time deodorization inside the drum. Because the deodorizing component is rotated within the drum, its position remains constant during drum rotation, preventing leakage of the deodorizing liquid from the deodorizing liquid bottle and ensuring stable deodorization operation. In this invention, long and short cotton cores overlap, with the long core inserted into the deodorizing liquid bottle. This allows the deodorizing liquid to be transferred to the short cores via capillary action. The connection between the short cores and the spray assembly then sprays the deodorizing liquid into the drum's interior, providing comprehensive deodorization even during drum rotation, thus improving air freshness. Cat litter boxes equipped with this deodorizing device can also achieve stable and comprehensive deodorization. Attached Figure Description

[0036] Pet cats, based on their biological instincts, have high requirements for their defecation environment. They need to bury their excrement in litter to prevent predators from smelling it. Therefore, pet cat owners provide them with litter boxes, also known as cat toilets, filled with cat litter. After relieving themselves in the litter, the cat will paw at the litter to cover its waste. However, the odor from the excrement lingers, affecting air freshness and promoting the growth of harmful bacteria. Currently, a pressing issue is how to achieve stable and comprehensive odor control inside existing cat toilets, especially those with rollers, and how to ensure continuous odor control even as the roller rotates.

[0037] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0038] like Figures 1-8 As shown, this embodiment provides a deodorizing device and a cat litter box. In this embodiment, the deodorizing device is installed in the mounting hole 101 of the roller 100, and the deodorizing device includes a deodorizing component 10, which is rotatably disposed in the mounting hole 101. The deodorizing component 10 includes a deodorizing liquid bottle 171, a long cotton core 172 inserted into the deodorizing liquid bottle 171, a short cotton core 173 overlapping the long cotton core 172, and a spray assembly. The spray assembly is connected to the short cotton core 173, and the short cotton core 173 conveys the deodorizing liquid in the deodorizing liquid bottle 171 to the spray assembly through the long cotton core 172. The spray assembly can spray the deodorizing liquid into the inside of the roller 100. This embodiment also provides a cat litter box, including a deodorizing device.

[0039] In this embodiment, a deodorizing device is used to achieve real-time deodorization inside the drum 100. Simultaneously, because the deodorizing component 10 in the deodorizing device is rotatably connected to the drum 100, the position of the deodorizing component 10 remains unchanged when the drum 100 rotates. This prevents leakage of the deodorizing liquid in the deodorizing liquid bottle 171 within the deodorizing component 10, ensuring stable deodorization operation. In this embodiment, the long cotton core 172 and the short cotton core 173 overlap, with the long cotton core 172 inserted into the deodorizing liquid bottle 171. This allows the deodorizing liquid in the deodorizing liquid bottle 171 to be transferred to the short cotton core 173 via capillary action. Through the connection between the short cotton core 173 and the spray assembly, the deodorizing liquid is sprayed into the inside of the drum 100 via the spray assembly, thus providing comprehensive deodorization inside the drum 100. Even when the drum 100 rotates, stable and comprehensive deodorization continues, improving air freshness. Cat litter boxes equipped with a deodorizing device can also achieve stable and comprehensive deodorization.

[0040] The specific structure of the deodorization device in this embodiment will be described below.

[0041] like Figure 1-3 As shown, in this embodiment, the deodorizing device includes a deodorizing component 10 and a rotating base 20. Optionally, the rotating base 20 is installed in the mounting hole 101 of the roller 100, and the deodorizing component 10 is connected to the rotating base 20 and rotatably disposed in the mounting hole 101. Thus, the deodorizing function of the deodorizing device is achieved through the deodorizing component 10, and the relative rotation between the deodorizing component 10 and the roller 100 is achieved by utilizing the rotating base 20.

[0042] Specifically, such as Figure 4-7 As shown, the deodorizing component 10 includes a rear cover 111, a housing 112, an inner frame 113, a hanging member 12, a PCB board 13, a main board 14, and a lighting lamp 15. The housing 112 is provided with a spray nozzle 1121. In this embodiment, the inner side of the rear cover 111 and the housing 112 enclose a receiving space, and the hanging member 12 is disposed on the outer side of the rear cover 111 for connecting the rotating chassis 20. Optionally, the rear cover 111 is provided with a locking block, and the housing 112 is provided with a locking interface. The locking block can engage with the locking interface to achieve a detachable connection between the rear cover 111 and the housing 112, facilitating internal maintenance of the deodorizing component 10. Figure 5 As shown, the hanger 12 includes a square plate and two inserts. Two inserts are symmetrically arranged on the square plate, and each insert has a connecting part and an abutting part. The connecting part is connected to the square plate, and the abutting part can press against the square plate. Optionally, as shown... Figure 4 As shown, a spray nozzle 1121 is provided through the outer casing 112 to facilitate the subsequent spraying of deodorizing liquid.

[0043] Furthermore, the inner frame 113 is disposed within the accommodating space. In this embodiment, the inner frame 113 is provided with a clearance opening, so that the locking block on the rear cover 111 can pass through the clearance opening and connect to the locking interface of the outer shell 112. Optionally, in other embodiments, the inner frame 113 may also be provided with a locking groove, so that after the locking block is engaged with the locking interface, it can be inserted into the locking groove, ensuring a tight connection between the rear cover 111, the inner frame 113, and the outer shell 112. Optionally, the PCB board 13 is disposed on the side of the inner frame 113, and the main board 14 is disposed on the bottom of the inner frame 113, thereby realizing the stable transmission of electronic signals of the deodorizing component 10.

[0044] Combination Figure 6 and Figure 7 As shown, the deodorizing component 10 also includes a light 15, a battery 16, a deodorizing liquid bottle 171, a long cotton wick 172, a short cotton wick 173, and a spray assembly. Specifically, as... Figure 4 As shown, the illumination lamp 15 is located at the bottom of the housing 112 to identify the position of the deodorizing component 10 within the roller 100, thus enabling accurate location of the deodorizing component 10 even in the dimly lit environment inside the roller 100. In other embodiments, the illumination lamp 15 can also be used to observe the working status of the deodorizing component 10, facilitating timely maintenance or replacement of the deodorizing component 10. The battery 16 is disposed in the accommodating space and installed inside the rear cover 111, electrically connected to the spray assembly, and used to drive the spray assembly.

[0045] Furthermore, the deodorizing liquid bottle 171, long cotton core 172, short cotton core 173, and spray assembly are disposed on the inner frame 113 within the accommodating space. The specific shape of the inner frame 113 is adapted to the deodorizing liquid bottle 171, long cotton core 172, short cotton core 173, and spray assembly, thereby improving the space utilization rate of the accommodating space and making the overall structure of the deodorizing component 10 compact, facilitating storage in the roller 100. Specifically, one end of the long cotton core 172 abuts against the bottom surface of the inner cavity of the deodorizing liquid bottle 171, and the other end of the long cotton core 172 passes through the bottle mouth of the deodorizing liquid bottle 171 and overlaps with one end of the short cotton core 173. Figure 6 As shown, the long cotton core 172 is arranged along the axis of the deodorizing liquid bottle 171, and the short cotton core 173 is arranged perpendicular to the long cotton core 172. This facilitates the capillary transport of the deodorizing liquid in the deodorizing liquid bottle 171 to the long cotton core 172, and then to the short cotton core 173. The lengths of the long cotton core 172 and the short cotton core 173 can be set as needed, and will not be described in detail here.

[0046] Furthermore, the spray assembly is connected to the short cotton core 173, enabling the deodorizing liquid to be sprayed into the interior of the roller 100 through the spray nozzle 1121. Specifically, the spray assembly includes a nozzle 181, a pressure spring 182, an atomizing plate 183, and an atomizing cover 184. Figure 7As shown, the nozzle 181 is connected to the short cotton core 173. In this embodiment, the nozzle 181 is sleeved on the outside of the short cotton core 173 and connected to the outside of the mouth of the deodorizing liquid bottle 171. This allows the nozzle 181 to cover the outside of the connection between the long cotton core 172 and the short cotton core 173, ensuring stable delivery of the deodorizing liquid to the spray assembly and achieving a tight connection between the spray assembly and the deodorizing liquid bottle 171. Optionally, the compression spring 182 is sleeved on the outside of the short cotton core 173, and the atomizing plate 183 is sealed at one end of the short cotton core 173. The atomizing plate 184 is used to fix the atomizing plate 183 to the nozzle 181. In this embodiment, the spray assembly can spray the deodorizing liquid delivered by the short cotton core 173 into the inside of the roller 100. Specifically, the atomizing plate 183 breaks the deodorizing liquid into liquid particles, which are then further sprayed into the inside of the roller 100 to achieve comprehensive deodorization. In other embodiments, other spray devices may be selected to achieve comprehensive deodorization of the deodorizing liquid inside the drum 100, which will not be elaborated here.

[0047] like Figure 8 As shown, the rotating chassis 20 includes a rotating inner ring 21, a counterweight 22, a bearing pressure plate 23, a bearing 24, a rotating outer ring 25, and a rotating hanger 26. The rotating inner ring 21 is provided with a mounting part 211, and the rotating hanger 26 is provided with a insertion groove 261. Specifically, the rotating outer ring 25 is installed in the mounting hole 101 of the roller 100, the rotating inner ring 21 is rotatably connected to the rotating outer ring 25, the counterweight 22 is disposed on the rotating inner ring 21, and the deodorizing component 10 is connected to the rotating inner ring 21. When the roller 100 drives the rotating outer ring 25 to rotate synchronously, the position of the rotating inner ring 21 remains unchanged under the action of the counterweight 22. This achieves a rotatable connection between the deodorizing component 10 and the roller 100, and ensures that the deodorizing component 10 remains in a fixed position under the influence of its connection with the rotating inner ring 21 and the gravity of the counterweight 22 when the roller 100 rotates. This allows the deodorizing component 10 to always be placed vertically, thereby preventing the deodorizing liquid bottle 171 from tilting or tipping over, preventing leakage of the deodorizing liquid, and ensuring that the deodorizing component 10 can perform comprehensive and stable deodorization operations under any circumstances of the roller 100, improving the utilization rate of the deodorizing device, and greatly improving the air freshness.

[0048] Specifically, the mounting portion 211 on the inner rotating ring 21 is configured with an arc-shaped structure to fit the shape of the counterweight 22. Further, the mounting portion 211 is provided with a protrusion, and the counterweight 22 is provided with a through hole. The protrusion and the through hole are correspondingly arranged, and the protrusion can be inserted into the through hole to achieve a stable connection between the inner rotating ring 21 and the counterweight 22. Optionally, the weight of the counterweight 22 can be designed as needed to ensure that the inner rotating ring 21 remains vertical under the weight of the counterweight 22 alone. Optionally, in this embodiment, the inner rotating ring 21 is rotatably connected to the outer rotating ring 25 via a bearing 24. Specifically, the inner side of the bearing 24 is sleeved on the outer side of the central shaft of the inner rotating ring 21, and the bearing pressure plate 23 is sleeved on the outer side of the bearing 24, with a certain gap between it and the inner rotating ring 21. It is connected to the outer rotating ring 25 by screws to ensure a stable connection between the bearing 24 and the outer rotating ring 25 and to achieve relative rotation between the inner rotating ring 21 and the outer rotating ring 25.

[0049] Furthermore, a receiving groove is provided on the central axis of the rotating inner ring 21, and two cylindrical grooves are provided in the receiving groove. The inner wall of the cylindrical grooves is threaded. Optionally, a connecting strip extends from the opening of the receiving groove. Correspondingly, the rotating hanger 26 includes a base plate and a socket sleeve. The socket sleeve is fixed to one side of the base plate, and a connecting hole and two threaded holes are provided through the base plate. Specifically, the connecting strip can be inserted into the connecting hole, and the screw passes through the threaded hole on the base plate and the cylindrical groove on the rotating inner ring 21 in sequence to fix the base plate to the rotating inner ring 21. In this embodiment, the threaded hole passes through the socket sleeve, so the screw can pass through the outside of the socket sleeve and tightly connect the socket sleeve, the base plate and the rotating inner ring 21, realizing a stable connection between the rotating hanger 26 and the rotating inner ring 21. When the rotating inner ring 21 rotates relative to the rotating outer ring 25, the rotating hanger 26 can rotate synchronously with the rotating inner ring 21 without interfering with the rotating outer ring 25. Furthermore, the insertion groove 261 is provided on the socket sleeve, and the groove opening of the insertion groove 261 faces upward. The hanger 12 of the deodorizing component 10 can be inserted into the insertion groove 261 from top to bottom, so that the abutting part of the insert block in the hanger 12 can press the side wall of the insertion groove 261 against the square plate, realizing the stable connection between the hanger 12 and the rotating hanger 26, thereby realizing the stable connection between the deodorizing component 10 and the rotating inner ring 21. Under the action of the bearing 24, the rotational connection between the deodorizing component 10 and the rotating outer ring 25 is completed, achieving the effect of relative rotation between the deodorizing component 10 and the roller 100, and realizing a comprehensive and stable deodorizing effect.

[0050] In this embodiment, a cat toilet is also provided, including the above-mentioned deodorizing device, so as to achieve a comprehensive and stable deodorizing operation inside the cat toilet.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
