Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, specifically to an intelligent pet toilet. Background Technology

[0002] A pet toilet is a device specifically designed for pets to relieve themselves, providing a convenient place for them and allowing owners to easily dispose of their pet's waste. With the increasing popularity of pet ownership and rising demands for home hygiene, pet toilets have become widely adopted. To improve convenience and hygiene, automated designs have been gradually introduced into existing technologies. For example, a motor drives a container filled with waste to a predetermined position, causing the discharge outlet to face downwards. Gravity then removes the waste from the outlet, achieving automated cleaning. However, these devices lack precise container positioning. After detecting a pet's exit, the motor rotates the container a fixed distance (i.e., according to a preset distance). Any slight misalignment or installation deviation in the container can cause it to fail to reach the predetermined position for waste removal during the automatic cleaning process, or even exceed the predetermined position, resulting in incomplete cleaning or equipment malfunction. This affects the reliability of the pet toilet, causing inconvenience to users and increasing maintenance costs. Utility Model Content

[0003] The purpose of this invention is to provide an intelligent pet toilet to solve the problem that the devices mentioned in the background art lack a facility for precise positioning of the litter box. After detecting that the pet has been removed from the litter box, the distance that the motor drives the litter box to rotate is fixed, which may cause the litter box to fail to accurately reach the predetermined position for excrement discharge, or even exceed the predetermined position.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an intelligent pet toilet, comprising: a support, wherein a chamber is provided on the support and a drive assembly for driving the chamber to rotate on the support;

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An intelligent pet toilet includes: a support 1, a chamber 2 rotatably mounted on the support 1, a drive assembly on the support 1 for driving the chamber 2 to rotate on the support 1; and a drain outlet 9 is provided on the arc-shaped side wall of the chamber 2 (according to...). Figure 3 , Figure 4 As shown, the drain outlet 9 is located at the top left side of the chamber 2, and the bottom of the support 1 has a discharge outlet 6; the support 1 is equipped with a photoelectric sensor 8 and a controller 21 (such as a PLC controller or microcontroller). The photoelectric sensor 8 includes a transmitting end and a detecting end, which are located on both sides of the chamber 2 (according to...). Figure 3 As shown, the transmitting end and the detection end are located on the front and rear sides of the chamber 2, respectively. Several openings 5 ​​are provided on both sides of the chamber 2. The openings 5 ​​are used for the light beam emitted by the transmitting end to pass through the chamber 2 and irradiate the detection end. During the rotation of the chamber 2, several openings 5 ​​pass through the photoelectric sensor 8 in turn.

[0035] It should be noted that there are four openings 5 ​​in total, and the four openings 5 ​​are labeled as the first opening, the second opening, the third opening, and the fourth opening respectively in a clockwise direction (clockwise direction is...). Figure 1 and Figure 3The first, second, and third openings are all located below the side wall of the chamber 2, with the first opening to the right of the second opening and the third opening to the left of the second opening. The fourth opening is located above the side wall of the chamber 2 and near the drain outlet 9. When the chamber 2 is aligned, the photoelectric sensor 8 corresponds to the second opening. When a pet enters the chamber 2 to relieve itself, it blocks the beam of light from the transmitter to the detector. The controller 21 receives information that the pet has entered the chamber 2. After the pet leaves the chamber 2, the beam of light from the transmitter shines back onto the detector through the second opening. At this time, the controller 21 controls the drive assembly to rotate the chamber 2 counterclockwise. At this time, the transmitter and the second opening are misaligned. The beam emitted from the transmitting end is blocked by the side wall of the chamber 2 until the transmitting end is aligned with the fourth opening (the third opening serves as a transition). At this time, the beam from the transmitting end shines onto the detection end through the fourth opening. After receiving the information, the controller 21 controls the drive component to stop working, causing the chamber 2 to stop rotating. At this time, the drain port 9 faces downward and is aligned with the discharge port 6, allowing the feces inside the chamber to be discharged through the drain port 9 and the discharge port 6 under the action of gravity. After the chamber 2 stays for a preset time (usually 3 seconds), the controller 21 then controls the drive component to move the chamber 2 in the opposite direction (clockwise rotation). After the transmitting end is aligned with the second opening, the controller 21 controls the drive component to stop working, causing the chamber 2 to reset.

[0036] It should also be noted that the support 1 can be placed directly on the toilet so that the feces discharged from the outlet 6 can fall directly into the toilet; and the support 1 can be placed on top of other collection devices so that the feces discharged from the outlet 6 can be collected.

[0037] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 3 The chamber 2 is equipped with a water supply component 3, which includes a water supply pipe and a solenoid valve 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 9. When the feces are discharged from the chamber 2, they will block the beam emitted by the transmitter passing through the opening 5, so that the feces can be detected when they pass through the drain outlet 9 of the chamber 2. At this time, the controller 21 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.

[0038] In this embodiment, as a further optimization, please refer to... Figure 4 , Figure 5 and Figure 6A partition 11 is installed inside the inner cavity of the hopper 2. The partition 11 is L-shaped and divides the inner cavity of the hopper 2 into a waste chamber 201 and a discharge chamber 202. The waste chamber 201 and the discharge chamber 202 are arranged vertically. The waste chamber 201 is connected to the sewage outlet 9. A filter screen 12 is installed inside the discharge chamber 202. The filter screen 12 divides the inner cavity of the discharge chamber 202 into a placement chamber 2021 and a temporary storage chamber 2022. The placement chamber 2021 is located outside the temporary storage chamber 2022 (according to...). Figure 4 As shown, the placement chamber 2021 is located to the right of the temporary storage chamber 2022, which is located below the waste chamber 201. The placement chamber 2021 is filled with cat litter, and an opening 14 is provided on the side wall of the partition 11 to connect the placement chamber 2021 with the waste chamber 201. After the cat finishes using the litter box in the placement chamber 2021, the chamber 2 rotates counterclockwise, allowing the cat litter to pass through the filter screen 12 and enter the temporary storage chamber 2022 for temporary storage, while the feces are blocked by the filter screen 12. As the chamber 2 continues to rotate, when the drain outlet 9 faces downward (at this time, the partition 11 restricts the cat litter inside the temporary storage chamber 2022), the feces enter the waste chamber 201 through the opening 14 and are then discharged from the drain outlet 9 and the discharge outlet 6. After the chamber 2 is reset, the cat litter flows back from the temporary storage chamber 2022 into the inner cavity of the placement chamber 2021.

[0039] It should be noted that the left side wall of compartment 2 (according to) Figure 4 (As shown in the direction) is an arc-shaped surface; during the process of using cat litter inside the placement cavity 2021 of the bin 2, when the controller 21 controls the drive component to work, causing the bin 2, after cleaning the feces, to rotate clockwise, the bin 2 will rotate until the emitting end of the photoelectric sensor 8 is aligned with the first opening. Then, the controller 21 controls the drive component to work, causing the bin 2 to rotate counterclockwise until the emitting end of the photoelectric sensor 8 is aligned with the second opening. At this time, the bin 2 completes the reset. By controlling the rotation of the bin 2 to align the emitting end with the first opening, it is ensured that the cat litter entering the temporary storage cavity 2022 can completely flow back into the placement cavity 2021.

[0040] In this embodiment, as a further optimization, please refer to... Figure 4 A garbage bag is fitted over the opening 14 and is located inside the garbage chamber 201. The garbage bag is used to collect the feces discharged from the opening 14, so that the feces discharged from the bin 2 can also be collected using the garbage bag. A pressure plate 15 is hinged in the inner cavity of the garbage chamber 201. The pressure plate 15 is used to press down the inlet of the garbage bag. When the bin 2 rotates counterclockwise to discharge the feces, the pressure plate 15 rotates under the action of gravity and does not contact the partition 11, 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 pressure plate 15 rotates under the action of gravity and presses the top of the garbage bag tightly and seals it again to prevent odor from escaping.

[0041] It should be noted that you should refer to [link / reference]. Figure 4 A cover plate 10 is snapped onto the left side wall of the silo 2; when collecting feces using garbage bags, the sewage outlet 9 is covered by the cover plate 10.

[0042] In this embodiment, as a further optimization, please refer to... Figure 4 and Figure 5 The inner cavity of the placement cavity 2021 is provided with a detachable baffle 13 (such as by snap-fit). The baffle 13 separates the placement cavity 2021 from the temporary storage cavity 2022. When the chamber 2 rotates counterclockwise, the cat litter inside the placement cavity 2021 can be discharged through the opening 14, making it more convenient to change the cat litter.

[0043] In this embodiment, as a further optimization, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 9 , Figure 10 and Figure 11 The support 1 includes a base 101 and two brackets 102. Slots are provided on both side walls of the support 1, and the two brackets 102 are respectively inserted into the two slots (the brackets 102 and the slots are connected by a snap-fit ​​mechanism). Support seats 20 are provided on the side of each bracket 102 that is close to each other. The support seats 20 are arc-shaped (semi-circular). The drive assembly includes a drive device 7 (such as a motor), a drive gear 19 mounted on the output shaft of the drive device 7, bearings 17, and an arc-shaped rack 16. There are two bearings 17, each located on one side wall of the chamber 2, supported by two support seats 20. The arc-shaped rack 16 is located on the side wall of the chamber 2, concentric with the bearings 17, and positioned above the drive gear 19, with the two gears meshing with each other. A photoelectric sensor 8 and a control... The controller 21 and the drive device 7 of the drive assembly are both installed inside the bracket 102 (the bracket 102 is composed of a housing and a cover connected together); because the support seat 20 supports the bearing 17, the chamber 2 is installed between the two brackets 102, so there is no fixed connection between the two brackets 102 and the chamber 2. The chamber 2 can be directly removed from the two brackets 102, and there are no electrical devices on the chamber 2, which makes it convenient to clean the chamber 2; the electrical devices (photoelectric sensor 8, controller 21 and drive device 7 of the drive assembly) are concentrated inside the bracket 102, reducing the overall size of the equipment. In addition, the base 101 and the bracket 102 are detachable, so that only the bracket 102 needs to be removed for maintenance. The bracket 102 is small in size, which makes it more convenient to return it to the factory for maintenance.

[0044] In this embodiment, as a further optimization, the bottom of the support 1 is detachably provided with a roller 4 (such as the roller 4 being fixed to the support 1 by bolts); by installing the roller 4 at the bottom of the support 1, the pet toilet is easy to move.

[0045] Example 2

[0046] As a further optimization of Example 1, please refer to Figure 6 , Figure 7 and Figure 8 The bottom of the support 1 is equipped with a cleaning assembly 18, which includes a collection box 181. The top of the collection box 181 is open. The collection box 181 is detachably mounted on the bottom of the support 1 (e.g., by snap-fit ​​or screw fixing). One side of the collection box 181 has a water inlet with a solenoid valve connected to an external water pipe. The other side of the collection box 181 has a water outlet that can be connected to a toilet. The bottom of the inner cavity of the collection box 181 slopes from the water inlet to the water outlet to facilitate the movement of feces inside the collection box 181 towards the water outlet. The inner cavity of 1 is equipped with a crushing component 182, which is located at the outlet of the collection box 181. The crushing component 182 includes a motor and blades mounted on the motor output shaft. After the controller 21 receives the feces discharge chamber 2, the controller 21 will control the solenoid valve of the inlet to open, so that water can be flushed into the interior of the collection box 181, flushing away the feces that have fallen into the collection box 181 and discharging them from the outlet. When the feces are discharged from the outlet, the controller 21 will also control the crushing component 182 to work, crushing the feces and reducing its volume.

[0047] It should be noted that when using cleaning component 18, the pet toilet will not use garbage bags to collect feces.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
