Description

Technical Field

[0001] This utility model belongs to the field of pet supplies technology, specifically relating to a sand-blocking component for a smart cat toilet and a corresponding smart cat toilet. Background Technology

[0002] As more and more people keep cats as pets, the issue of cat elimination has always been a concern for owners. Cats have specific requirements for defecation; if the litter box isn't cleaned promptly, the cat may stop defecating or change its littering spot. Furthermore, cat excrement often has a strong odor. In addition, if there are multiple cats, cleaning up their feces each time is time-consuming and laborious, making these issues very troublesome for cat owners. Therefore, an automatic cat litter box that can clean promptly, safely, and without odor is needed to solve the problem of difficult individual cleaning for cat owners.

[0003] Currently, the common solutions to these problems are simple litter boxes or cat toilets. However, existing cat toilets can only perform basic screening and lack the integration and application of artificial intelligence, such as: monitoring the status of the litter box equipment, recognizing cats when using the toilet, analyzing and managing the cat's weight and health, monitoring the environmental status, and providing timely reminders. Furthermore, current technology cannot collect data on the frequency of a cat's excretions, nor does it offer remote control via mobile phone. Therefore, users cannot be notified immediately if a problem occurs.

[0004] In particular, some cats that are adept at digging will spill litter from the litter box. To prevent this, a baffle is usually installed at the opening of the litter box. However, this baffle takes up space in the litter box, affecting the cat's experience. Therefore, a user-friendly smart litter box is needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sand-blocking component for a smart cat litter box and a corresponding smart cat litter box.

[0006] To solve the above-mentioned technical problems, the first aspect of this utility model provides a sand-blocking component for a smart cat litter box, which is detachably installed at the ball compartment opening of the smart cat litter box. The sand-blocking component includes a sand-blocking plate, the two ends of which are respectively connected to the inner wall of the ball compartment opening, so that the sand-blocking plate is detachably installed at the lower opening of the ball compartment opening to cover at least the bottom part of the lower opening of the ball compartment opening and prevent cat litter from being exposed.

[0007] Preferably, the two ends of the sand baffle are hinged to the inner wall of the ball pit opening, allowing the sand baffle to rotate. The sand baffle assembly includes a first limiting protrusion and a second limiting protrusion, which are disposed on the inner wall of the ball pit opening. By rotating the sand baffle, it has a sand-blocking position and a sand-pouring position. In the sand-blocking position, the lower edge of the sand baffle is confined between the first and second limiting protrusions to cover at least the bottom portion of the lower opening of the ball pit opening and prevent cat litter from being exposed. In the sand-pouring position, the lower edge of the sand baffle extends beyond the first limiting protrusion, creating a gap between the lower edge of the sand baffle and the lower edge of the ball pit opening to allow cat litter to be poured out.

[0008] Preferably, the first limiting protrusion is closer to the outside of the ball compartment than the second limiting protrusion, and the protrusion height of the first limiting protrusion is lower than the protrusion height of the second limiting protrusion.

In the first stage, the ball chamber is driven to rotate clockwise around the rotation axis. During the rotation of the ball chamber, excrement mixed with cat litter is sieved out by the waste-sieving component and rolls along the waste-sieving component until the upper opening rotates to the waste outlet. The sieved excrement rolls down through the upper opening into the waste collection chamber below the waste outlet. After the first stage ends, the second stage begins. In the second stage, the ball chamber is driven to rotate counterclockwise around the rotation axis. Cat litter sieved by the sieve component flows back to its initial state. The smart cat litter box also has a waste-cleaning mode, which is configured to drive the ball chamber to rotate counterclockwise around the rotation axis. During the rotation of the ball chamber, cat litter rolls to the lower opening, which rotates to the waste outlet.

[0062] To make the technical problem solved by this utility model clearer, the present utility model is further described below with reference to embodiments and accompanying drawings. The specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0063] like Figures 1 to 20 This is a specific embodiment of the intelligent cat litter box provided by this utility model. The intelligent cat litter box includes a support base 100, a ball chamber 200, and a drive mechanism. The support base 100 is provided with a waste outlet 140 (e.g., ...). Figure 3 (As shown), in this embodiment, the support base 100 is provided with support legs 130. A waste collection chamber 300 is installed below the waste outlet 140. The waste collection chamber 300 is used to collect pet cat excrement and can be easily disassembled and installed at the waste outlet 140. Figure 2 This shows the configuration of the waste collection chamber 300 installed at the waste outlet 140. Figure 3 This shows the state of the waste outlet after the waste collection chamber 300 has been removed.

[0064] like Figure 11 and Figure 12 As shown, the ball chamber 200 is connected to the rotating shaft 220 (see also...). Figure 12 The drive mechanism is installed on the support base 100 and is used to drive the ball chamber 200 to rotate around the rotation axis. The drive mechanism can be a motor.

[0065] like Figure 1 As shown, the ball chamber 200 is provided with a ball chamber opening 210 serving as the cat's inlet and outlet. A sieve assembly is installed inside the ball chamber 200. The ball chamber opening 210 includes an upper opening and a lower opening, so as to... Figure 1 From the perspective shown, with the axis of rotation as the boundary, the portion of the ball-shaped opening 210 located to the right of the axis of rotation is the upper opening, and the portion of the ball-shaped opening 210 located to the left of the axis of rotation is the lower opening. In the intelligent cat toilet of this invention, the ball-shaped opening 210 serves as the inlet and outlet for the pet cat and the outlet for excrement.

[0066] like Figure 4 As shown, the intelligent cat litter box has a waste-cleaning mode, which includes a first stage and a second stage. In the first stage, the ball chamber 200 is driven to rotate clockwise around the rotation axis. During the rotation of the ball chamber 200, the excrement mixed with the cat litter is sieved out by the waste-sieving component and rolls along the waste-sieving component until the upper opening rotates to the waste outlet 140. The sieved excrement rolls down through the upper opening into the waste collection chamber 300 below the waste outlet 140. After the first stage ends, the second stage begins. In the second stage, the ball chamber 200 is driven to rotate counterclockwise around the rotation axis 220. The cat litter sieved by the sieve component flows back to its initial state, and the cat litter returns to the clean cat litter storage area.

[0067] like Figure 5 As shown, the intelligent cat litter box also has a cleaning mode. The cleaning mode is set to drive the ball chamber 200 to rotate counterclockwise around the rotation axis 220. During the rotation of the ball chamber 200, the cat litter rolls until it reaches the lower opening. The lower opening rotates to the litter outlet 140 for easy collection of cat litter.

[0068] like Figure 1 , Figures 18 to 20As shown, a sand-blocking assembly 400 is detachably installed at the lower opening of the ball chamber opening. The sand-blocking assembly 400 includes a sand-blocking plate 430. Both ends of the sand-blocking plate 430 are respectively connected to the inner wall of the ball chamber opening 200, so that the sand-blocking plate 430 can be detachably installed at the lower opening of the ball chamber opening 200 to cover at least the bottom part of the lower opening of the ball chamber opening 200 and prevent cat litter from being exposed, thereby preventing the cat from digging the cat litter out from the front during the toilet process.

[0069] The sand baffle 430 of this utility model only covers the bottom part of the lower opening, so as to avoid occupying too much sand compartment space and affecting the toilet experience.

[0070] The sand-blocking component 400 of this utility model is more suitable for cats that dig a lot in the sand. For other pet cats, the sand-blocking component 400 can be removed in order to avoid taking up space in the litter box and affecting their toileting experience.

[0071] The two ends of the sand baffle 430 are hinged to the inner wall of the ball chamber opening, allowing the sand baffle 430 to rotate. The sand baffle assembly 400 includes a limiting assembly 420, which includes a first limiting protrusion 422 and a second limiting protrusion 421. The first limiting protrusion 422 and the second limiting protrusion 421 are disposed on the inner wall of the ball chamber opening. By rotating the sand baffle 430, the sand baffle 430 has a sand-blocking position and a sand-pouring position. In the sand-blocking position, the lower edge of the sand baffle 430 is confined between the first limiting protrusion 422 and the second limiting protrusion 421 to cover at least the bottom portion of the lower opening of the ball chamber 200 opening and prevent cat litter from protruding. Figure 6 As shown, when in the litter pouring position, the lower edge of the baffle plate 430 extends beyond the first limiting protrusion 422, creating a gap between the lower edge of the baffle plate 430 and the lower edge of the opening of the ball chamber 200. At this time, cat litter can be conveniently poured out from this gap.

[0072] like Figure 19 As shown, the first limiting protrusion 422 is closer to the outside of the ball chamber 200 than the second limiting protrusion 421, and the protrusion height of the first limiting protrusion 422 is lower than that of the second limiting protrusion 421. The first limiting protrusion 422 and the second limiting protrusion 421 are positioned at the middle of the lower edge of the sand baffle 430. Based on this design, when the user needs to remove waste cat litter, the sand baffle 430 can be bent upwards past the first limiting protrusion 422, allowing the sand baffle 430 to move freely and creating a gap for easy cat litter discharge. After discharging the cat litter, the sand baffle 430 can be pressed back.

[0073] The limiting assembly 420 also includes at least one third limiting protrusion, which is used to enhance the blocking strength of the sand baffle 430.

[0074] like Figure 18 As shown, the sand-blocking assembly 400 includes a hinge hole 410, which is disposed on the inner wall of the opening of the ball chamber 200, so as to be hinged to the end of the sand-blocking plate 430 via a hinge shaft.

[0075] like Figures 6 to 10 As shown, the litter sieving assembly includes a filter screen 500 and a partition plate 800 connected to the filter screen 500. Both the filter screen 500 and the partition plate 800 are connected to the inner wall of the ball chamber 200, and a litter transfer area is formed between the filter screen 500, the partition plate 800 and the inner wall of the ball chamber 200. The litter sieving action is performed by rotating the ball chamber 200. In this embodiment, the litter sieving action is performed by rotating the ball chamber 200 clockwise.

[0076] The filter 500 allows cat litter to enter the litter transfer area while blocking excrement from entering the litter transfer area. The filter 500 separates the cat litter and the excrement in the cat litter. The space between the partition 800 and the inner wall of the ball chamber 200 is used to temporarily store the filtered cat litter. After entering the litter transfer area, the cat litter continues to rotate within the litter transfer area to achieve temporary storage. The blocked excrement rolls from the surface of the filter 500 to the surface of the partition 800 and then rolls down to the waste outlet 140 of the smart cat litter box, and then falls into the waste collection chamber.

[0077] like Figure 7 and Figure 8 As shown, the horizontal cross-section of the partition 800 has a first profile 801, which protrudes and bends toward the side away from the rotation axis of the sphere 200. The vertical cross-section of the partition 800 has a second profile 802, which is perpendicular to the horizontal plane and the rotation axis 220 of the sphere 200, so that the partition 800 forms an inwardly curved surface to gather the excrement toward the central area.

[0078] Therefore, the design of the partition in this utility model makes the partition have a waste sliding channel, which facilitates the waste to slide into the collection chamber.

[0079] The first contour 801 is an arc contour, specifically as follows: Figure 7 The shape shown is inverted U; as... Figure 8 As shown, the second contour 802 is arc-shaped, and the second contour 802 protrudes and curves outward toward the opening of the ball chamber 200.

[0080] Since both the first and second contours of this utility model are arc-shaped, the excrement can be gathered in the middle of the partition, preventing the excrement from falling randomly into the area outside the toilet opening.

[0081] like Figure 6 As shown, the upper edge of the filter 500 is detachably connected to the lower edge of the partition 800 to form a connection area A. The connection area A can be fixedly connected or it can be an integrally formed structure.

[0082] In the sieve assembly of this utility model, the plane of the filter screen 500 is not lower than the surface of the partition 800, that is, the filter screen 500 is not behind the surface of the partition 800, and the filter screen 500 can be flush with or higher than the surface of the partition. Specifically, the plane of the filter screen 500 is flush with the surface of the partition 800 or has an angle difference of 5° to 10°.

[0083] like Figures 11 to 14 As shown, a clamping system 120 is provided between the rotating shaft 220 and the support base 100 to rotatably mount the rotating shaft 220 of the smart cat toilet ball compartment 200 onto the support base 100 of the smart cat toilet.

[0084] like Figure 12 and Figure 13 As shown, the clamp system 120 includes a clamp body extending along the outer peripheral surface of the pivot 220 of the ball chamber 200. One end of the clamp body is rotatably fixed to a first position of the support base 100, for example, by means of a hinge assembly. The first position is located on one side of the pivot 220. The other end of the clamp body is provided with a rotatable handle 121. The rotatable handle 121 has a handle portion, a hinge portion, and a locking portion. The hinge portion is used to hinge with the other end of the clamp body, allowing the rotatable handle 121 to rotate relative to the clamp body. The hinge portion can use a combination of a hinge shaft and a hinge hole. The locking portion is used to lock with a second position of the support base 100, located on the other side of the pivot 220.

[0085] The rotatable handle 121 is configured such that pulling the handle upward causes it to rotate around the hinge, disengaging the locking part from the support base 100, thus facilitating the removal of the ball chamber 200 from the support base 100. Both the clamp body and the handle are arc-shaped.

[0086] like Figure 14As shown, the clamp system is in the unlocked state, at which point the ball chamber 200 can be easily removed from the support base 100. During use, the user pulls the handle to disengage the locking part and open the clamp system. Therefore, the ball chamber can be removed in a single, convenient, and quick action.

[0087] In the clamp system of this utility model, the clamp system 120 includes a torsion spring 122, which is sleeved on the hinge portion. One end of the torsion spring 122 abuts against the rotatable handle 121, and the other end abuts against the other end of the clamp body, so as to elastically reset the rotatable handle 121 when the handle portion is released. Through the torsion spring, the handle can automatically spring back; after pulling the handle to open the clamp, it can automatically spring back, facilitating the locking of the ball chamber after the clamp body is closed.

[0088] The clamp body is further provided with a first roller 123 and a second roller 124, which are rotatably mounted on the clamp body. The surfaces of the first roller 123 and the second roller 124 are in contact with the surface of the rotating shaft 220, so that when the rotating shaft 220 rotates, the first roller 123 and the second roller 124 are driven to rotate by rolling friction, thus facilitating the rotation of the rotating shaft 220. The rollers provide support and also make the rotation of the shaft smoother, avoiding sliding friction.

[0089] like Figure 2 , Figure 3 and Figure 15 As shown, the waste collection chamber 300 includes a main body with an upper opening that communicates with the waste outlet. The main body has an extension that extends upwards around its circumference, supporting the opening of the waste bag. The extension has a first region 310 and a second region connected to the first region 310. The first region 310 is located at the end of the main body, and both ends of the first region 310 extend beyond the corner between the end and side of the main body. The first region 310 is a soft rubber region, and the second region is a hard rubber region. In this invention, the extension is partly soft rubber and partly hard rubber, with the soft rubber extending across both corners, allowing the user to easily pull the drawstring of the disposable waste bag, facilitating the installation and securing of the disposable waste bag.

[0090] like Figure 15 As shown, the main body of the waste collection chamber 300 is provided with a handle end 340, which is opposite to the end of the first region 310. The handle end 340 is provided with a hook 341 for easy fixing of the disposable waste collection bag.

[0091] The two corners formed between the handle end 340 and the two sides are provided with guide reinforcing ribs 350 to enhance strength and guide the drawstring of the disposable stool bag to slide upward.

[0092] The main body of the waste collection chamber is provided with tracks on both sides. The tracks have track bodies 330 that are perpendicular to the side walls of the main body of the waste collection chamber. The tracks of the main body of the waste collection chamber match the tracks in the support base 100 of the smart cat toilet. Figure 3 The support base track 150, which matches the waste collection chamber track, is shown. The front end of the track of the waste collection chamber body is curved upwards. This guides the installation of the waste collection chamber, allowing the user to directly push the waste collection chamber into the bottom position of the support base from the front, without having to manually align the waste collection chamber.

[0093] The waste collection chamber 300 is equipped with a first sensor 320, which works in conjunction with a second sensor within the support base 100 of the smart cat litter box. The first sensor 320 and the second sensor work together to detect whether the waste collection chamber 300 is properly installed. Specifically, the first sensor 320 can be a magnet, and the second sensor is a magnetic sensor. The position of the magnet on the waste collection chamber is not limited; it works in conjunction with the magnetic sensor on the support base to determine the installation of the waste collection chamber.

[0094] like Figure 3 , Figure 16 and Figure 17 As shown, a light curtain system is installed at the waste outlet 140 to detect whether the waste collection chamber 300 is full. The light curtain system includes a first light curtain panel 910 and a second light curtain panel 920 disposed relative to the first light curtain panel 910. Figure 3 As shown, the first light curtain plate 910 and the second light curtain plate 920 are positioned opposite each other at the toilet opening 140.

[0095] In this embodiment, the first light curtain panel 910 is provided with a pair of first light emitting units 950 and a pair of first light receiving units 960, and the second light curtain panel 920 is provided with a pair of second light emitting units 980 and a pair of second light receiving units 970. The first light emitting units 950 and the second light receiving units 970 are correspondingly arranged, and the second light receiving units 970 are used to receive the light emitted by the first light emitting units 950. The second light emitting units 980 and the first light receiving units 960 are correspondingly arranged, and the first light receiving units 960 are used to receive the light emitted by the second light emitting units 980.

[0096] Specifically, the first optical emitting unit 950 and the first optical receiving unit 960 are arranged in a cross arrangement, and the second optical receiving unit 970 and the second optical emitting unit 980 are arranged in a cross arrangement. That is, the pair of first optical emitting units 950 are separated by a first optical receiving unit 960, and the pair of second optical emitting units 980 are separated by a second optical receiving unit 970. Figure 17 As shown, the cross-arranged transmitting and receiving units can avoid mutual interference between light beams and cover the largest area with the fewest number of LEDs possible.
