Description

Technical Field

[0001] This invention relates to pet products, specifically a pet toilet. Background Technology

[0002] As people's living standards improve, pets, as man's best friend, have entered more and more families, bringing countless joys to people's lives. Pets such as cats, dogs, and birds all have the need to relieve themselves. Therefore, more and more pet toilets have appeared on the market.

[0003] Take a cat litter box as an example. A cat litter box, also known as a cat litter trough, is a container for cats to excrete waste. Existing cat litter boxes usually include a pet activity chamber. When in use, cat litter is placed in the pet activity chamber. After a trained cat defecates in the pet activity chamber, the cat litter adheres to the feces and clumps the feces together, thus burying the cat feces.

[0004] Because feces easily accumulate on the inner walls of the litter box, it needs to be cleaned after a period of use to remove odors. Therefore, existing litter boxes typically have a removable pet activity chamber. The aforementioned removable pet activity chamber can be referenced in Chinese Utility Model Patent ZL202120568017.2 (authorization announcement number CN215074563U) entitled "A Litter Box", and Chinese Utility Model Patent ZL202123136631.0 (authorization announcement number CN216314642U) entitled "An Easy-to-Disassemble and Wash Smart Litter Box".

[0005] Furthermore, existing pet toilets often require electrical components such as sensors, sterilization and deodorization devices, and lighting devices to be installed inside the pet activity chamber. These electrical components are connected to an external power source via power cords, which means that the pet activity chamber must be disconnected from the power supply before it can be disassembled for cleaning. This makes the disassembly process before cleaning the pet activity chamber quite complicated. Moreover, if the user forgets to disconnect the power supply before cleaning the pet activity chamber, there is a significant safety hazard during the cleaning process. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is to provide a pet toilet that is powered on after installation and automatically de-energized after disassembly, in view of the above-mentioned technical status quo.

[0007] The second technical problem to be solved by the present invention is to provide a pet toilet that allows the installation and removal of the pet activity chamber to be synchronized with the power supply.

[0008] The third technical problem to be solved by the present invention is to provide a pet toilet in which the base can still ensure electrical safety after the shell is removed.

[0009] The fourth technical problem to be solved by the present invention is to provide a pet toilet in which dirt on the disassembly and assembly parts of the housing can be easily cleaned after the housing is removed.

[0010] The fifth technical problem to be solved by the present invention is to provide a pet toilet that maintains electrical conductivity between the housing and the base during the rotation of the housing.

[0011] The technical solution adopted by the present invention to solve the first technical problem mentioned above is as follows: a pet toilet, comprising: a base and a housing detachably mounted on the base, the interior of the housing having an inner cavity for a pet to move in, characterized in that: the base is provided with a first power transmission part connected to a power source, the housing is provided with a second power transmission part, and the two are joined together to allow power to be transmitted between the two.

[0012] The term "joining" as used above refers to the continuous spatial distribution of the two objects being joined, but is not limited to a specific connection method. Joining can be a contact between the first and second power transmission parts, a threaded connection, an adhesive bonding, a snap-fit ​​method similar to a light bulb clip, a snap-fit ​​method like a buckle on a backpack strap, or a snap-fit ​​method, such as a base with a recessed portion, where the first power transmission part has a groove extending circumferentially on the side wall of the recessed portion, the housing has a plug-in portion that inserts into the recessed portion, and the second power transmission part has a rib extending circumferentially on the plug-in portion and engaging with the groove. The power transmission between the first and second power transmission parts can be achieved through contact between conductive parts or through electromagnetic induction.

[0013] The technical solution adopted by the present invention to solve the second technical problem mentioned above is as follows: the base has a first adapter part, the shell has a second adapter part, and the two are adapted together in a detachable manner. Furthermore, the first power transmission part is provided on the first adapter part, and the second power transmission part is provided on the second adapter part. The detachment part between the shell and the base is exactly the part where the power is switched on and off, so that no additional switch is needed to turn on the power after the shell is installed, and the installation, removal and power switching of the pet activity chamber can be completed in one step.

[0014] The technical solution adopted by the present invention to solve the third technical problem mentioned above is as follows: the first adapter is a groove provided on the top of the base, and the second adapter is a connecting part provided on the outer surface of the shell, which is inserted into the groove from top to bottom. The assembly and disassembly structure of the connecting part and the groove is simple, and by placing the first power transmission part in the groove, although the first power transmission part is exposed after the shell is disassembled, it is not easy to be accidentally touched and cause electric shock because it is in the groove, which can effectively improve the safety of the base. The second power transmission part is located on the outer surface of the shell, which also makes the second power transmission part easier to dry after being exposed to water.

[0015] The technical solution adopted by the present invention to solve the fourth technical problem mentioned above is as follows: the second power transmission part is a metal component. Because metal components can come into contact with water, they are not easily damaged by water like electronic components, and the conductivity of metal components is not affected after drying, thus facilitating the cleaning of the housing.

[0016] To facilitate the separation and emptying of pet feces, the shell is mounted on the base in a manner that allows it to rotate about a basically horizontal axis of rotation, and has an outlet communicating with the inner cavity. This outlet is located on the rotation trajectory of the shell and is used to empty the feces from the inner cavity. The shell is provided with a screen located in the inner cavity.

[0017] To increase the pet's activity space inside the housing, the screen is rotatably connected to the housing via a connecting shaft parallel to the housing's rotation axis. When the screen rotates to a point where a portion of it contacts the inner surface of the housing, the portion of the screen other than that portion is in close proximity to or against the inner surface of the housing. The housing is also equipped with a first drive mechanism for driving the screen to rotate, and this first drive mechanism is engaged with the second power transmission unit to allow power to be transmitted between the two. Through the engagement of the second power transmission unit and the first drive mechanism, the first drive mechanism can be energized to drive the screen to rotate, so that when the pet defecates, the portion of the screen other than the portion in contact with the housing is in close proximity to or against the inner surface of the housing. This allows the screen and the housing to jointly define a larger activity space for the pet, thereby increasing the pet's activity space inside the housing.

[0018] "When the screen rotates to the point where a portion of it contacts the inner surface of the housing, the portion of the screen other than that portion is in close proximity to or in contact with the inner surface of the housing" means that when a portion of the screen contacts the inner surface of the housing, the remaining portion after removing the contacting portion is in close proximity to the inner surface of the housing, or, after removing the contacting portion, the remaining portion is in contact with the inner surface of the housing.

[0019] To facilitate support for the rotation of the housing, the base has opposing first and second sidewalls. The groove includes a first groove at the top of the first sidewall and a second groove at the top of the second sidewall. The connecting part includes a first connecting part and a second connecting part that are coaxially arranged and spaced apart. The straight line containing the center line of the first connecting part and the center line of the second connecting part is the rotation axis of the housing. The first connecting part is located in the first groove, and the second connecting part is located in the second groove. The first connecting part and the second connecting part serve as the rotation axis of the housing, thereby supporting the rotation of the housing.

[0020] The technical solution adopted by the present invention to solve the fifth technical problem mentioned above is as follows: the first power transmission part is a probe disposed on the bottom wall of the first groove, and the second power transmission part is a conductive ring sleeved on the first connecting part.

[0021] To prevent the second power transmission part from wearing out, a first annular groove is provided on the peripheral wall of the first connecting part, and the second power transmission part is housed in the first annular groove, thereby preventing the second power transmission part from protruding from the first connecting part and making the second power transmission part less prone to wear.

[0022] To reduce friction during shell rotation and to facilitate axial positioning of the shell, a second annular groove is provided on the peripheral wall of the first connecting part, and a first roller is provided on the bottom wall of the first groove, the first roller being disposed in the second annular groove; and / or, a second annular groove is provided on the peripheral wall of the first connecting part, and a first roller is provided on the bottom wall of the second groove, the first roller being disposed in the second annular groove.

[0023] Compared with the prior art, the advantages of the present invention are as follows: by setting a first power transmission part that can be connected to a power source on the base and a second power transmission part on the housing, and by engaging the first and second power transmission parts after the housing is installed, the housing and the base are energized to supply power to the components installed on the housing. After the housing is disassembled, the first and second power transmission parts are separated, thereby de-energizing the housing and the base. This allows for the one-step installation, removal, and power switching of the pet activity chamber, eliminating the need for additional power connection to the installed pet activity chamber or power disconnection to the pet activity chamber before cleaning. It also reduces the safety hazards associated with forgetting to manually disconnect the power before cleaning the housing. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] like Figures 1-10 The image shown is a first preferred embodiment of the present invention.

[0037] The pet toilet in this embodiment is a cat litter box, which includes the following main components: base 1, shell 2, screen 3, first drive mechanism 4, second drive mechanism, waste collection box 6, and base 7.

[0038] The housing 2 is cylindrical and mounted on the base 1 in a manner that allows it to rotate about a generally horizontal axis of rotation. The housing 2 has an inner cavity 20, and its first end 2a has an opening 241 for the pet to enter and exit the inner cavity 20 (see...). Figure 1 and Figure 3 The peripheral wall of the housing 2 has an outlet 21 communicating with the inner cavity 20 (see...). Figures 7-10The outlet 21 is for emptying feces from the inner cavity 20. The base 1 is basin-shaped (see...). Figure 4 ), and is mounted on base 7, the interior of which is provided a waste collection box 6 located below base 1 (see Figures 7-10 Furthermore, the base 1 has a channel 14 on its peripheral wall that communicates with the waste collection box 6 (see...). Figure 4 This allows the housing 2 to rotate so that its outlet 21 corresponds to the channel 14, so that the feces poured out from the inner cavity 20 enter the collection box 6 through the channel 14.

[0039] One side of the screen 3 is rotatably connected to the inner surface of the housing 2 via a connecting shaft (not shown in the figure) parallel to the rotation axis of the housing 2. When the screen 3 rotates to the point where a portion of it contacts the inner surface of the housing 2, the portion of the screen 3 other than that portion is in contact with the inner surface of the housing 2. Specifically, the screen 3 has opposing first surfaces 3a and second surfaces 3b (see...). Figure 7 Furthermore, under the combined motion of the screen 3 rotating relative to the housing 2 and the housing 2 rotating relative to the base 1, the positional relationship between the housing 2 and the screen 3 includes the following first, second, and third states: In the first state, the screen 3 is basically horizontal, and its first surface 3a is in contact with the inner surface of the housing 2, with the outlet 21 located above the screen 3, thereby placing the sand X above the screen 3 (see...). Figure 7 After the pet enters the inner cavity 20 and defecates on the sand X, both the shell 2 and the screen 3 rotate counterclockwise until the second state, where the outlet 21 faces downwards, the screen 3 is basically tilted, and the first surface 3a of the screen 3 is separated from the inner surface of the shell 2, while the second surface 3b faces the outlet 21. This facilitates the separation of the mixture of feces Y and sand X by the screen 3. The separated feces Y is poured out through the outlet 21, while the separated sand X falls through the mesh of the screen 3 and is located in the space between the first surface 3a of the screen 3 and the inner surface of the shell 2 (see...). Figure 8 Subsequently, both shells 2 rotate clockwise, so that outlet 21 is located at the upper part of shell 2, and sand X is located at the bottom of inner cavity 20 (see...). Figure 9 Then rotate the screen 3 clockwise so that the screen 3 is basically vertical and its first surface 3a is in contact with the inner surface of the shell 2. At this time, the shell 2 and the screen 3 are in the third state (see Figure 10 Finally, rotate both the shell 2 and the screen 3 counterclockwise to the first state to complete the process of separating the pet's excrement.

[0040] The first drive mechanism 4 is a first motor located outside the housing 2 (see...). Figure 6The connecting shaft (not shown in the figure) is fixedly connected to the screen 3, and one end of it extends out of the inner cavity 20 and is connected to the output end of the first motor, thereby driving the screen 3 to rotate. The second drive mechanism includes a second motor 51 (see figure 51) located on the outer wall of the base 1. Figure 1 The first gear 52 located at the output end of the second motor 51 (see...) Figure 4 ), and the second gear 22 located at the second end 2b of the housing 2 (see Figure 1 The base 1 has an opening that allows the first gear 52 to mesh with the second gear 22, thereby driving the housing 2 to rotate (see...). Figure 4 ).

[0041] The base 1 has opposing first sidewalls 1a and second sidewalls 1b. The top of the first sidewall 1a is provided with a first groove 12, and the top of the second sidewall 1b is provided with a second groove 13 (see...). Figure 4 and Figure 5 The outer surface of the housing 2 is provided with horizontal first connecting parts 23 at both ends (see...). Figure 2 ) and the second connecting part 24 (see Figure 3 The center line of the first connecting part 23 and the center line of the second connecting part 24 form the rotation axis of the housing 2. The first connecting part 23 is inserted into the first groove 12 from top to bottom, and the second connecting part 24 is inserted into the second groove 13 from top to bottom, so that the first connecting part 23 and the second connecting part 24 serve as the rotating shaft of the housing 2, thereby supporting the rotation of the housing 2. The bottom wall of the first groove 12 is provided with a first power transmission part 11 connected to the power source, and the peripheral wall of the first connecting part 23 is fitted with a second power transmission part 231. The first power transmission part 11 is a probe, and the second power transmission part 231 is a metal conductive ring (see...). Figure 2 This allows the first power transmission unit 11 and the second power transmission unit 231 to engage, enabling the transmission of electrical energy between them and thus powering the rotation of the screen 3. The second power transmission unit 231 and the first drive mechanism 4 are connected by a line to be energized (not shown in the figure).

[0042] like Figure 2 As shown, the first connecting portion 23 has a first annular groove 232 on its peripheral wall, and the second power transmission portion 231 is housed in the first annular groove 232, thereby preventing the second power transmission portion 231 from protruding from the first connecting portion 23 and making the second power transmission portion 231 less prone to wear. The first connecting portion 23 also has a second annular groove 233 on its peripheral wall, and a first roller 17 is provided on the bottom wall of the first groove 12, which is located in the second annular groove 233. The first side wall 1a of the base 1 also has a third groove 15 inside the first groove 12, and the second gear 22 is housed in the third groove 15 from top to bottom.

[0043] like Figure 3 and Figure 4 As shown, the second connecting portion 24 is annular, and the inner annular surface of the second connecting portion 24 forms an opening 241. A second roller 16 is provided on the bottom wall of the second groove 13. The second roller 16 contacts the outer annular surface of the second connecting portion 24, thereby reducing the frictional force of the housing 2 rotation and making the housing 2 rotate more smoothly.

[0044] Example 2

[0045] The difference between this embodiment and embodiment 1 is that the screen 3 in this embodiment is fixed on the housing 2 and cannot rotate relative to the housing 2.

[0046] The specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
