Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a swing-type cleaning cat litter box. Background Technology

[0002] As living standards continue to improve, more and more families are choosing pets for daily companionship, especially in economically developed cities where the proportion of pet owners is higher. However, due to the limited living space per capita and restrictions on pets going out in economically developed cities, more pet owners tend to prefer felines, which do not require much space to roam. Felines require specialized litter boxes, which must be cleaned and disposed of regularly.

[0003] Currently, the main way to solve the problem of cat excretion in pet cats is through litter boxes. However, existing litter boxes usually do not have a litter cleaning function, which means that cats can urinate or defecate on the litter. The surface of the litter is contaminated with feces and excrement, which causes the litter to produce a noticeable odor, making both the owner and the cat uncomfortable. After a few days of use, the contaminated litter needs to be discarded and replaced with new litter, resulting in a lot of waste and environmental problems, as well as increased costs. This is undoubtedly a major pain point for cat owners. Utility Model Content

[0035] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Please refer to the following: Figures 1 to 9 This embodiment provides a swing-type cleaning litter box, including a base 100, a cat compartment 200, and a drive device. The cat compartment 200 is rotatably mounted on the base 100, and the interior of the cat compartment 200 forms a chamber with an inlet 270. One inner side wall of the chamber serves as a sitting or lying position for placing cat litter for the cat to excrete. The cat can enter the sitting or lying position inside the cat compartment 200 through the inlet 270. The cat compartment 200 is provided with a water inlet for injecting cleaning water into the cat compartment 200, and the outer wall of the cat compartment 200 has a water outlet 234. The drive device is driven to the cat compartment 200 to swing the cat compartment 200 back and forth, thereby washing the cat litter inside the cat compartment 200.

[0037] As can be seen, in this embodiment of the swing-type cleaning litter box, when there is cat litter in the cat compartment 200 that needs to be cleaned, a predetermined amount of cleaning water is added into the cat compartment 200 through the water inlet, and the cat compartment 200 is driven to swing back and forth by the drive device to wash the cat litter in the cat compartment 200. After the cat litter is cleaned, the wastewater in the cat compartment 200 can be filtered and discharged through the water outlet 234, thereby cleaning the cat litter to remove the small amount of excrement and obvious odor on the surface of the cat litter, so that the cat litter can be reused, saving the cost of cat litter use, and is clean and hygienic, with a good user experience.

[0038] In this embodiment, the litter box also includes a screening plate 220, which is disposed on one side of the sitting / lying position. The screening plate 220 has multiple screening ports 222 to divide the chamber into a sitting / lying chamber and a screening chamber 221. The cat hold 200 has a discharge port 260 so that when the cat hold 200 rotates, the cat litter and cat feces in the sitting / lying chamber are screened through the screening plate 220. This allows the cat litter to pass through the screening ports 222 of the screening plate 220 into the screening chamber 221, while the cat feces are discharged through the discharge port 260. In this way, the litter box can... This system automatically separates large feces from cat litter. Large feces are first removed from the cat compartment 200, then the cat litter is washed by swaying from side to side to remove surface contaminants. After washing, there is virtually no noticeable odor. Detergent can be added to the washing water to enhance the cleaning and deodorizing effect. The cat litter is made of PLA (polylactic acid), a biodegradable material, and is typically processed into egg-shaped particles with a diameter of 3mm-5mm. Its smooth surface facilitates cleaning and improves the comfort for cats walking on it. Because the cat litter is completely biodegradable and has a small particle size, even if trace amounts are carried into the wastewater collection compartment 110 by cat feces and discharged into the sewer, it will not have an adverse impact on the environment.

[0039] Specifically, the litter box also includes a wastewater collection chamber 110, which is located within the base 100. When the cat pod 200 rotates, wastewater from the chamber is discharged into the wastewater collection chamber 110 through the drain hole 234. The wastewater collection chamber 110 is equipped with a drain outlet 111, allowing for the centralized collection of wastewater from cleaning the litter box. The top of the base 100 is open, forming the opening of the wastewater collection chamber 110. The bottom of the cat pod 200 rests on the top opening of the wastewater collection chamber 110, and at least partially, the bottom of the cat pod 200 is contained within the wastewater collection chamber 110. With a large volume, the water used for cleaning cat litter in the cat storage 200 is concentrated in the wastewater collection tank 110 and will not overflow. The top opening of the wastewater collection tank 110 is arc-shaped to fit the outer contour of the cat storage 200. A brush sealing ring is provided between the opening of the wastewater collection tank 110 and the outer periphery of the cat storage 200 to prevent the wastewater collected in the wastewater collection tank 110 from splashing out. In addition, a second water level sensor 120 is provided in the wastewater collection tank 110, and a second solenoid valve is provided in the drain outlet 111. The controller can control the drain outlet 111 to open in time to discharge wastewater based on the water volume signal detected by the second water level sensor 120 in the wastewater collection tank 110.

[0040] Furthermore, the litter box also includes a first water level sensor 240 and a controller. The first water level sensor 240 is disposed in the cat compartment 200 so that the controller controls the amount of cleaning water injected into the cat compartment 200 based on the water volume signal detected in the chamber by the first water level sensor 240. This allows a predetermined amount of cleaning water to be added to the cat compartment 200 to prevent excessive water overflow. The first water level sensor 240 and the second water level sensor 120 can be conventional water level detection components.

[0041] In this embodiment, the litter box also includes a water injection component, which includes a water injection pipe 310 and a first solenoid valve 320. The cat compartment 200 has a perforation along its rotation axis. The water injection pipe 310 is mounted on the base 100, and one end of the water injection pipe 310 extends into the cat compartment 200 through the perforation. The first solenoid valve 320 is mounted on the water injection pipe 310 and is electrically connected to the controller. The other end of the water injection pipe 310 is connected to a water source so that the controller can control the water injection pipe 310 to open and automatically add cleaning water into the cat compartment 200 through the first solenoid valve 320. Both the first solenoid valve 320 and the second solenoid valve are water inlet solenoid valves from Haier washing machines. Of course, other existing solenoid valves can also be used. The perforation is set along the rotation axis of the cat compartment 200, and the outer surface of one end of the water injection pipe 310 does not contact the perforation to avoid structural interference when the cat compartment 200 rotates or swings, thereby improving the stability and reliability of the structure.

[0042] Specifically, multiple screening ports 222 are located at the end of the screening plate 220 near the sitting / lying position, and a sand baffle 223 is located at the end of the screening plate 220 away from the sitting / lying position. The excretion port 260 is located adjacent to the sand baffle 223 to prevent cat litter from leaking out through the excretion port 260. The screening ports 222 on the cat compartment 200 that are close to the sand baffle 223 and away from the screening plate 220 are designed so that when the cat litter rotates to separate the cat litter from the feces, large pieces of feces cannot pass through the screening ports 222 and slide along the screening plate 220 and the sand baffle 223 to the excretion port 260 and be discharged into the wastewater collection chamber 110 for centralized collection. The smaller cat litter particles can pass through the multiple screening ports 222 and enter the screening chamber 221. Since the sand baffle 223 is located between the screening chamber 221 and the excretion port 260, it can effectively prevent cat litter from being discharged through the excretion port 260. The structural design is reliable.

[0043] Furthermore, the litter box also includes a sand-water separation plate 210. The sitting / lying position is located on the sand-water separation plate 210. The sand-water separation plate 210 is set in the chamber. The sand-water separation plate 210 is provided with multiple filter holes to form a partition cavity between the sand-water separation plate 210 and the inner wall of the chamber. The water outlet 234 is set on the outer wall of the partition cavity so that the sewage in the chamber can be discharged into the sewage collection chamber 110 through the multiple filter holes, the partition cavity and the water outlet 234 when the cat box 200 rotates.

[0044] The partition chamber is equipped with a partition 232 to divide it into a washing chamber 231 and a drying chamber 233. A water outlet 234 is located on the side wall of the drying chamber 233. The washing chamber 231 is positioned closer to the screening chamber 221 than the drying chamber 233. The sand-water separation plate 210 has a first set of filter holes 211 and a second set of filter holes 212. The first set of filter holes 211 is connected to the washing chamber 231, and the second set of filter holes 212 is connected to the drying chamber 233. When the cat litter is swung left and right to wash it, the cat litter is located on the first set of filter holes 211 of the sand-water separation plate 210. The cat litter passes through the sieve during the swung washing process within the cat compartment 200. The filter 222 enters and exits the sieving chamber 221. Alternatively, protrusions can be provided on the inner wall of the sieving chamber 221 to improve the cleaning effect of the cat litter by rubbing against the surface of the cat litter. When the cat litter is clean and the wastewater needs to be discharged, the water in the washing chamber 231 can be discharged into the wastewater collection chamber 110 in sequence through the first set of filter holes 211, the chamber, the second set of filter holes 212, the drying chamber 233, and the water outlet 234. The partition 232 is provided with several connecting holes so that a small amount of water in the washing chamber 231 can be discharged into the wastewater collection chamber 110 in sequence through the connecting holes, the drying chamber 233, and the water outlet 234, thereby ensuring that there is basically no water retention in the washing chamber 231.

[0045] In this embodiment, the litter box also includes a drying component disposed on the seat 100. The drying component includes a drying channel 410, a heater 420, and a fan unit 430, so that the air blown out by the fan unit 430 is heated by the heater 420 and blown into the chamber through the drying channel 410 and the water outlet 234 to dry the cleaned cat litter, thereby ensuring that the cat will not feel damp when it enters the cat house 200 to sleep, thus ensuring the healthy life of the pet cat.

[0046] One end of the drying channel 410 extends upward through the wastewater collection chamber 110, while the other end extends upward outside the wastewater collection chamber 110. The height of the other end of the drying channel 410 is higher than that of the first end. A heater 420 and a fan unit 430 are located at the other end of the drying channel 410, so that the water outlet 234 of the cat litter compartment 200 corresponds to one end of the drying channel 410 during the litter drying process, allowing the fan unit 430 to blow out water. After being heated by the heater 420, the air is blown sequentially through the drying channel 410 and the water outlet 234 to the drying chamber 233 of the partition chamber, the second set of filter holes 212 and the chamber, thereby drying the cat litter on the second set of filter holes 212. Specifically, the larger partition chamber is divided into a washing chamber 231 and a drying chamber 233 by the partition 232, so that the hot air blown out by the drying component is concentrated and blown onto the cat litter surface in the cat compartment 200 through the drying chamber 233 and the second set of filter holes 212, thereby improving the drying speed and efficiency of the cat litter and reducing wind power loss.

[0047] It is worth mentioning that, due to the large volume and width of the sewage collection chamber 110, when the sewage used for cleaning cat litter in the cat storage 200 is discharged into the sewage collection chamber 110, the water level in the sewage collection chamber 110 is lower than the height of one end of the drying channel 410. The water in the sewage collection chamber 110 will basically not flow into the drying channel 410. Of course, even if a small amount of water splashes into the drying channel 410, it will not come into contact with the heater 420 and fan unit 430 on the other end of the drying channel 410, and will basically not damage the heater 420 and fan unit 430. Of course, one end of the drying channel 410 in the sewage collection chamber 110 can also be set near the edge side wall of the sewage collection chamber 110 to prevent water from flowing into the drying channel 410 as much as possible, so as to ensure the safety and reliability of the product.

[0048] In this embodiment, the driving device includes a gear ring 630, a gear 620, and a motor 610. The motor 610 is mounted on the base 100, the gear ring 630 is sleeved on one end of the cat compartment 200, the gear 620 is connected to the output shaft of the motor 610, and the gear 620 meshes with the gear ring 630 so that the motor 610 drives the gear 620 to rotate, and the meshing of the gear 620 with the gear ring 630 drives the cat compartment 200 to rotate. Optionally, the motor 610 is a 42CM06 stepper motor 610 from Leadshine Intelligent Technology Co., Ltd., and the reduction gearbox of the motor 610 is an 80:1 worm gear reducer.

[0049] The cat storage compartment 200 has multiple annular tracks 650 spaced apart on its outer periphery, and the base 100 has multiple sets of rollers 640. Each set of rollers 640 consists of two rollers, which are spaced apart. The outer periphery of each roller 640 has an annular groove. Each annular track 650 is movably embedded in the annular groove of each set of rollers 640. Each annular track 650 is supported and rotated by two rollers 640. The base 100 and the cat storage compartment 200 are both installed inside the outer shell 700.

[0050] Specifically, the inner wall of the cat compartment 200 is equipped with an infrared sensor 250. The infrared sensor 250 is a BGX-35N diffuse reflection sensor from Boyi Precision Technology Co., Ltd., which is used to detect whether there is a pet cat in the cat compartment 200. This is to prevent the pet cat from being injured in the cat compartment 200 during the cat litter cleaning process. If the infrared sensor 250 detects a pet cat in the cat compartment 200, the controller will control the cat litter box to stop the cat litter cleaning operation. The controller uses an STM32 MCU as the main controller.

[0051] Furthermore, a magnetic flux sensor 660 is installed on the base 100, and a magnet is installed on the cat compartment 200. The controller controls the drive device to rotate the cat compartment 200 to reset to the initial standby state based on the signal detected by the magnetic flux sensor 660, in preparation for the next swing cleaning process. The controller also controls the drive device to rotate the cat compartment 200 to preset rotation angles corresponding to the cat litter screening state, feces discharge state, cat litter washing state, cat litter draining state, and cat litter drying state. The preset rotation angles corresponding to each state of the cat compartment 200 are set by the input program before leaving the factory, so that the cat compartment 200 can switch to the corresponding working state by rotating to the corresponding preset rotation angle. The cat litter box has a high degree of automation, is easy to use, and basically requires no manual intervention.

[0052] It should be noted that, as Figure 8As shown, the litter box is in litter washing mode. The drive device drives the cat compartment 200 to swing left and right to wash the litter inside the cat compartment 200. The liquid level of the washing water is P. During the process of the cat compartment 200 swinging left and right to wash the litter, the washing water will basically not overflow from the drain outlet 260 and the water outlet. Even if the washing water splashes onto the sitting and lying surface inside the cat compartment 200, the sitting and lying surface will be dried in the litter drying mode to ensure that the pet cat will not feel obvious dampness or discomfort when sitting or lying in the cat compartment 200.

[0053] Furthermore, the litter box also includes a waste disposal assembly, which includes a waste pipe, a shredder 520, and a waste pump 510. The inlet of the shredder 520 is connected to the outlet 111 of the wastewater collection chamber 110, and the outlet of the shredder 520 is connected to one end of the waste pipe. The other end of the waste pipe is equipped with a waste pump 510. The shredder 520 uses a commonly used 4052 DC motor 610 feces crushing motor to shred large pieces of cat feces. The outlet of the shredder 520 is connected to the waste pipe and the waste pump 510. The waste pump 510 is a Sanyo XQB55-496 impeller-type wastewater drainage pump. The shredded feces dissolve in the wastewater and are discharged by the suction of the waste pump 510. This configuration allows for the centralized collection and discharge of large pieces of cat feces and wastewater in the wastewater collection chamber 110, making it convenient to use.

[0054] When using, such as Figure 5 As shown, the litter box is in its initial daily state. The cat normally sits or lies in the designated sitting or lying position inside the cat compartment 200, relieving itself on the litter. The litter box is activated when the litter in the cat compartment 200 needs cleaning, ensuring the cat is not inside the compartment. Figure 6 As shown, the drive unit drives the cat compartment 200 to rotate counterclockwise, causing cat litter and feces in the sitting / lying position to be separated by the screening plate 220. Smaller cat litter particles pass through multiple screening ports 222 and enter the screening chamber 221, while feces cannot pass through the screening ports 222 and slide along the screening plate 220 and the litter baffle 223 to the excrement outlet 260. Figure 7 As shown, feces are then discharged through the excrement outlet 260 into the sewage collection chamber 110 for centralized collection. Then, the drive device rotates the cat compartment 200 clockwise to put it into a litter cleaning state. Figure 8 As shown, in the litter cleaning state, the drive device drives the cat bin 200 to swing left and right, thereby washing the litter inside the cat bin 200. After the litter is cleaned, the drive device drives the cat bin 200 to rotate clockwise to the draining state, as shown. Figure 5As shown, water in the cat storage 200 can be discharged sequentially through the second set of filter holes 212, the drying chamber 233, and the water outlet 234 into the sewage collection chamber 110. A small amount of water in the washing chamber 231 can be discharged sequentially through the connecting hole of the partition 232, the drying chamber 233, and the water outlet 234 into the sewage collection chamber 110 for centralized collection and discharge. After water and sand are separated, the driving device drives the cat storage 200 to rotate until the water outlet 234 corresponds to one end of the drying channel 410. Figure 9 As shown, the air blown out by the fan unit 430 is heated by the heater 420 and then blown through the drying channel 410 and the water outlet 234 into the drying chamber 233 of the partition chamber, the second set of filter holes 212 and the cat compartment 200 in sequence, thereby drying the cat litter in the cat compartment 200 and the surface of the sitting and lying position. Finally, after the cat litter is dried, the driving device drives the cat compartment 200 to rotate to the initial daily state.

[0055] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0056] This utility model relates to a swing-type cleaning litter box. When there is litter in the litter compartment 200 that needs cleaning, a predetermined amount of cleaning water is added into the litter compartment 200 through the water inlet. The drive device drives the litter compartment 200 to swing back and forth, thereby washing the litter inside. After the litter is cleaned, the wastewater in the litter compartment 200 is filtered and discharged through the water outlet 234. This process cleans the litter, removing small amounts of excrement and noticeable odors from the surface, allowing the litter to be reused, saving on litter usage costs. It is clean and hygienic, providing a better user experience.
