A collision surface is formed at the stroke tail end of the arc-shaped rack; the driving motor drives the driving gear to rotate, so that the arc-shaped rack drives the bin body to rotate to an inverted state, excrement naturally falls under the action of gravity, and when the driving gear continues to rotate, the tooth part of the driving gear makes contact with the collision surface and applies pressure, so that the bin body further deflects; and when the gear is separated from the collision surface, the bin body swings back under the action of gravity due to loss of supporting force and collides with the driving gear to form a shaking effect, so that the excrement adhered to the inner wall of the bin body is effectively shaken off.

Description

Technical Field

[0001] This utility model relates to the field of pet products, specifically to an anti-adhesion pet toilet. Background Technology

[0002] A pet toilet is a device specifically designed for pets to relieve themselves, providing a convenient place for pets and facilitating the centralized disposal of pet feces by owners. To improve the convenience and hygiene of pet toilets, automated designs have been gradually introduced into existing technologies. These designs involve using a motor to drive a container filled with feces to a predetermined position, causing the discharge outlet of the container to face downwards. Gravity then removes the feces from the discharge outlet, thus achieving automated cleaning. For example, the publication document CN119896174A discloses such an intelligent pet toilet. When the container is upright, the discharge outlet faces upwards, allowing pets to enter and defecate. When the container is inverted, the discharge outlet faces downwards, used to discharge feces from inside the container.

[0003] However, the device has certain limitations in use. Specifically, the defecation process relies solely on the gravity of the inverted bin to allow the feces to fall out naturally. However, because pet feces may adhere to the inner wall of the bin due to factors such as humidity and stickiness, it is difficult to clean it completely by gravity alone, resulting in residue problems. This not only affects the hygiene of subsequent use but may also breed bacteria, produce odors, and reduce the user experience. Utility Model Content

[0004] The purpose of this invention is to provide an anti-adhesion pet toilet, which solves the problem of incomplete cleaning of existing pet toilets.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: an anti-adhesion pet toilet, comprising a support and a chamber, wherein an arc-shaped rack is provided on the outer wall of the chamber, and a drive gear is provided on the support to mesh with the arc-shaped rack. The drive gear is used to drive the chamber to rotate to an upright or inverted state via the arc-shaped rack.

[0006] The arc-shaped rack has a collision surface at the end of its stroke. The collision surface is used to cause the inverted chamber to rotate a certain angle under the action of gravity when each tooth of the drive gear passes over the collision surface, and to cause the next adjacent tooth to hit the collision surface and generate vibration.

[0007] Preferably, the support is provided with a drive motor for driving the drive gear to rotate, the bottom of the support is provided with a discharge port, and the chamber is provided with a sewage discharge port. When the chamber is in the upright position, the sewage discharge port faces upward, and when the chamber is in the inverted position, the sewage discharge port faces downward and coincides with the discharge port.

[0008] Preferably, the collision surface is an inclined surface or an arc surface.

[0009] Preferably, the chamber is equipped with an ultraviolet germicidal lamp.

[0010] Preferably, the bottom of the inner cavity of the chamber is provided with an anti-stick layer, which is snapped into the chamber.

[0011] Preferably, the anti-stick layer comprises two layers of three-proof fabric, and a roller is provided between the two layers of three-proof fabric.

[0012] Preferably, the hopper is provided with a partition that divides the inner cavity of the hopper into a waste chamber and a discharge chamber, which are arranged vertically. The waste chamber is connected to a sewage outlet. The discharge chamber is provided with a filter screen that divides the inner cavity of the discharge chamber into a placement chamber and a temporary storage chamber. The partition is provided with an opening for connecting the placement chamber and the waste chamber.

[0013] Preferably, the partition is provided with two guide blocks, which are located on both sides of the opening and inside the placement cavity.

[0014] Preferably, a mounting frame is hinged inside the waste chamber, and a counterweight is provided on the mounting frame. A waste bag is provided inside the waste chamber for fitting over the opening, and the counterweight is used to press down the inlet of the waste bag after the chamber body is reset.

[0015] Preferably, the counterweight is a metal rod, and the partition is provided with a magnetic element for attracting the metal rod.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The drive motor drives the drive gear to rotate, causing the arc rack to rotate the bin to an inverted state, so that the feces fall naturally under the action of gravity;

[0018] 2. The teeth of the drive gear contact the collision surface and are controlled by the drive motor to continue rotating, applying pressure to the collision surface and causing the arc-shaped rack to carry the chamber to continue rotating. When the drive gear continues to rotate and the teeth no longer contact the collision surface, the support force on the chamber disappears. Under the action of gravity, the chamber rotates in the opposite direction, causing the collision surface to collide with the drive gear, causing the chamber to shake. This effectively shakes off the feces adhering to the inner wall of the chamber, avoiding the residue problems that may occur when cleaning by simply relying on gravity in the traditional way, and ensuring that the feces are completely discharged.

[0019] 3. By using the three-proof fabric inside the chamber, the possibility of feces adhering to the chamber is greatly reduced. At the same time, when the chamber rotates, the roller rolls between the two layers of three-proof fabric, causing dynamic deformation of the surface of the upper layer of three-proof fabric, preventing feces or other objects from adhering to the three-proof fabric layer, ensuring that feces inside the chamber are completely discharged, and ensuring the hygiene of the pet toilet for long-term use.

Detailed Implementation

[0032] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Example 1

[0034] Please see Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 8 An anti-adhesion pet toilet includes: a support 1 and a chamber 2. The support 1 includes a base 101 and two brackets 102. Two slots are provided on the top wall of the support 1, and the two brackets 102 are respectively inserted into the two slots, so that the brackets 102 and the support 1 are snapped together. The bracket 102 is composed of a shell and a cover that are snapped together. A controller 22 (PLC controller microcontroller), a photoelectric sensor 21, and a drive motor 20 are installed inside the shell, concentrating the electrical equipment on the bracket 102. The output shaft of the drive motor 20 extends to the outside of the shell and is connected to a drive gear 18. Each of the two brackets 102 has a support base 19 (semi-circular) on its side closest to each other. Bearings are installed on both the left and right sides of the chamber 2, and two bearings are respectively... Supported by two bases 19, the compartment 2 is placed directly on two brackets 102, enabling modular assembly of the pet toilet. Several openings 7 are provided on both the left and right sides of the compartment 2, and the openings 7 are arranged in a ring around the bearing. The photoelectric sensor 21 includes a transmitting end and a detecting end, which are respectively installed inside the two brackets 102. A discharge port 17 is provided at the bottom of the base 101, and a sewage outlet 3 is provided on the arc-shaped outer wall of the compartment 2. The above technical features are the same as those of an intelligent pet toilet with publication number CN119896174A, and the way the compartment 2 rotates according to the position of the openings 7 and the photoelectric sensor 21 is also the same as the working method of the compartment in the published document.

[0035] It should be noted that the bottom of the base 101 is detachably equipped with casters (such as the casters being fixed to the base 101 by bolts); the casters make the pet toilet easy to move (this technical solution is the same as the technical solution of an intelligent pet toilet with publication number CN119896174A).

[0036] Please see Figure 1 , Figure 2 , Figure 3 and Figure 10The left and right side walls of the hopper 2 are equipped with arc-shaped racks 6, the center of which is the same as the center of the bearing of the hopper 2; the arc-shaped racks 6 are located above the drive gear 18 and the two mesh with each other; the end wall of the arc-shaped rack 6 is the collision surface 8 (that is, the top surface of the arc-shaped rack 6 is the collision surface 8); when the hopper 2 is in the upright position, the drain outlet 3 faces upward; when the hopper 2 is in the inverted position, the drain outlet 3 faces downward.

[0037] It should be noted that you should refer to [link / reference]. Figure 11 In order to facilitate the passage of the teeth of the drive gear 18 over the collision surface 8, the collision surface 8 can be an inclined surface or an arc surface.

[0038] Working principle: After the pet finishes using the litter box 2, the controller 22, based on the signal from the photoelectric sensor 21, controls the drive motor 20 to rotate the drive gear 18, causing the arc-shaped rack 6 to rotate the litter box 2 until the litter box 2 is inverted, moving the drain outlet 3 directly above the discharge outlet 17. (The way the controller 22 controls the drive motor 20 to rotate the litter box 2 based on the signal from the photoelectric sensor 21 is the same as the technical solution of an intelligent pet toilet with publication number CN119896174A, and will not be described in detail here.) At this point, the teeth of the drive gear 18 have moved out from between the teeth of the arc-shaped rack 6 and are in contact with the collision surface 8. The controller 22 continues to control the drive motor 20 to rotate the drive gear 18, and the teeth of the drive gear 18 will apply pressure to the collision surface 8. The arc-shaped rack 6 continues to rotate with the chamber 2. When the drive gear 18 continues to rotate and the teeth no longer contact the collision surface 8, the support force on the chamber 2 disappears. Under the action of gravity, the chamber 2 rotates in the opposite direction, causing the collision surface 8 to collide with the drive gear 18, resulting in the chamber 2 shaking. This causes the feces inside the chamber 2 to be discharged through the drain port 3 and the discharge port 17. Then, the drive gear 18 continues to rotate, causing the chamber 2 to repeat the above shaking process until the controller 22 controls the drive motor 20 to rotate in the opposite direction. At this time, the chamber 2 reverses and resets (this reset process is the same as the technical solution in the intelligent pet toilet disclosure document with publication number CN119896174A, and will not be described in detail here). By shaking the chamber 2, the probability of feces adhering to the inside of the chamber 2 is reduced.

[0039] It should be noted that, through the cooperation of the opening 7 and the photoelectric sensor 21, the controller 22 obtains information that the chamber 2 is in an inverted state. At this time, the controller 22 will control the drive gear 18 to continue rotating for a period of time according to the setting, and then control the drive motor 20 to reverse, so that the number of times the chamber 2 shakes is preset.

[0040] It should also be noted that a water supply component 24 is connected to the chamber 2. The water supply component 24 includes a water supply pipe and a solenoid valve installed on the water supply pipe. The water supply pipe is connected to an external water supply device. When no cat litter is placed inside the chamber 2 (at this time, the pet toilet can also be used as a dog toilet), when the pet finishes using the toilet inside the chamber 2, the chamber 2 rotates, causing the feces to be discharged from the chamber 2 through the drain outlet 3. When the feces are discharged from the chamber 2, they will block the beam emitted by the transmitter passing through the opening 7, so that the feces can be detected when they pass through the drain outlet 3 of the chamber 2. At this time, the controller 22 will control the solenoid valve to open and supply water to the inside of the chamber 2 through the water supply pipe for rinsing the inside of the chamber 2. This is suitable for pet toilets without cat litter (this technical solution is the same as the technical solution in the publication document of an intelligent pet toilet with publication number CN119896174A, and will not be described in detail here).

[0041] In this embodiment, as a further optimization, please refer to... Figure 2 The chamber 2 is equipped with an ultraviolet germicidal lamp 15, which is used to sterilize the interior of the chamber 2. The ultraviolet germicidal lamp 15 includes a lamp holder and a lamp tube. The lamp holder is mounted on the bracket 102, and the lamp tube extends through the bearing of the chamber 2 into the inner cavity of the chamber 2, so that the electrical equipment is centrally mounted on the bracket 102. When removing the chamber 2, the lamp tube needs to be removed from the lamp holder first.

[0042] In this embodiment, as a further optimization, please refer to... Figure 1 , Figure 6 and Figure 9 The bottom of the inner cavity of the silo 2 is provided with an anti-adhesion layer 5, which is snapped into the silo 2 (the connection between the anti-adhesion layer 5 and the silo 2 is achieved by a snap-fit), making it easy to remove the anti-adhesion layer 5. The anti-adhesion layer 5 is made of two layers of three-proof fabric sewn together, with a roller 23 (iron rod) between the two layers of three-proof fabric. The three-proof fabric can prevent feces or other objects from adhering to the bottom of the inner cavity of the silo 2. During the rotation and inversion of the silo 2, the roller 23 rolls between the two layers of three-proof fabric, causing dynamic deformation of the surface of the upper layer of three-proof fabric, preventing feces or other objects from adhering to the three-proof fabric, and ensuring that the feces in the silo 2 are completely discharged.

[0043] Example 2

[0044] As a further optimization of Example 1, please refer to Figure 1 , Figure 2 and Figure 6The inner cavity of the compartment 2 is equipped with a partition 9 (L-shaped), which divides the inner cavity of the compartment 2 into a garbage compartment 201 and a discharge compartment 202. The garbage compartment 201 and the discharge compartment 202 are arranged vertically. The garbage compartment 201 is connected to the sewage outlet 3. The inner cavity of the discharge compartment 202 is equipped with a filter screen 10, which divides the inner cavity of the discharge compartment 202 into a placement compartment 2021 and a temporary storage compartment 2022. The placement compartment 2021 is located to the right of the temporary storage compartment 2022. The placement compartment 2021 is filled with cat litter. The partition 9 is equipped with a mechanism to connect the placement compartment 2021 and the garbage compartment 2022. The cat has a connected opening 11. After the cat finishes using the litter box in the placement chamber 2021, the chamber 2 rotates counterclockwise, allowing the litter to pass through the filter screen 10 and enter the temporary storage chamber 2022 for temporary storage. The feces are blocked by the filter screen 10. As the chamber 2 continues to rotate, when the drain outlet 3 faces downward (at this time, the partition 9 restricts the litter inside the temporary storage chamber 2022), the feces enter the garbage chamber 201 through the opening 11 and are then discharged from the drain outlet 3 and the discharge outlet 17. After the chamber 2 is reset, the litter flows back from the temporary storage chamber 2022 into the inner cavity of the placement chamber 2021.

[0045] It should be noted that when the pet toilet is used as a cat litter box, the process of controller 22 controlling the chamber 2 to reset is the same as the technical solution for chamber reset in the public document of an intelligent pet toilet with publication number CN119896174A, and will not be described in detail here.

[0046] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 5 The partition 9 is provided with two guide blocks 12, which are located on both sides of the opening 11 and inside the placement cavity 2021. The guide blocks 12 are used to guide the feces through the opening 11, so that the feces can pass through the opening 11 easily.

[0047] In this embodiment, as a further optimization, please refer to... Figure 4 and Figure 6 A mounting frame 13 is hinged inside the garbage chamber 201, and a counterweight 14 is provided on the mounting frame 13. A garbage bag is provided inside the garbage chamber 201 for fitting onto the opening 11. The garbage bag is used to collect the feces discharged from the opening 11, so that the feces discharged from the bin 2 can also be collected using the garbage bag. When the bin 2 rotates counterclockwise to discharge feces, the mounting frame 13 and the counterweight 14 rotate under the action of gravity and do not contact the partition 9, releasing the pressure on the garbage bag and allowing the feces to enter the garbage bag normally. When the bin 2 rotates clockwise to reset, the mounting frame 13 and the counterweight 14 rotate in the opposite direction under the action of gravity, so that the counterweight 14 presses on the inlet of the garbage bag, pressing and sealing the top of the garbage bag again to prevent odor from escaping.

[0048] In this embodiment, as a further optimization, please refer to... Figure 4 and Figure 6 The counterweight 14 is a metal rod (iron rod), and the partition 9 is equipped with a magnetic component (magnetic block) to attract the metal rod, so that the counterweight 14 can press the garbage bag more tightly. The magnetic force of the magnetic block on the metal rod is less than the weight of the counterweight 14, so that when the compartment 2 is inverted, the mounting frame 13 and the counterweight 14 can rotate to release the seal on the garbage bag.

[0049] It should be noted that you should refer to [link / reference]. Figure 1 , Figure 3 , Figure 5 and Figure 6 When the drain outlet 3 is not in use, the drain outlet 3 can be sealed with the cover plate 4. The drain outlet 3 and the cover plate 4 are interlocked.

[0050] It should also be noted that, please refer to Figure 5 In order to discharge the cat litter inside the placement chamber 2021, a baffle 16 is installed inside the placement chamber 2021 to separate the placement chamber 2021 from the temporary storage chamber 2022. When the chamber 2 rotates counterclockwise, the cat litter inside the placement chamber 2021 can be discharged through the opening 11, making it more convenient to change the cat litter.

[0051] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
