Description

Technical Field

[0001] The invention relates to the technical field of pet equipment, and in particular to a cat litter box. Background Art

[0002] A cat litter box is a pet excretion basin used to hold cat litter. After the pet's feces are discharged into the cat litter pile, they will be wrapped by the cat litter and become dry lumps. The dry feces can then be shoveled out.

[0003] There are two ways to separate feces from cat litter in existing cat litter boxes. One is manual, that is, manually scooping the feces out of the cat litter box; the other is automatic separation, that is, separating the feces for collection by rotating or reversing. The manual scooping method is time-consuming and laborious, and there is also the problem of forgetting. The automatic rotation method is easy to cause the lumps to disperse due to the strong collision force, resulting in a large number of lumps being mixed into the cat litter again, affecting the use time of the cat litter. Summary of the invention

[0004] In view of the shortcoming of the prior art that the cat litter is easy to disperse, the object of the present invention is to provide a cat litter box that is not easy to disperse.

[0005] To solve the above problems, the present invention provides the following technical solutions: In a first aspect, an embodiment of the present application provides a cat litter box, comprising: a box body; A carrier plate, disposed in the basin body, for carrying cat litter; A cleaning mechanism, which can be translated inside the basin to clean the cat litter; A collecting mechanism, disposed on the side of the basin body, for collecting feces cleaned by the cleaning mechanism; The sensor is used to sense the cat entering and exiting the basin. Whenever the cat enters and exits the basin, the sensor controls the cleaning mechanism to perform a cleaning operation.

[0006] In some embodiments, the cleaning mechanism includes a cleaning member, a transmission member, and a clearance groove provided on both sides of the basin body; The cleaning piece is arranged in the basin body and located on the upper side of the carrier plate, and the cleaning piece is used to clean the cat litter; The transmission member drives the cleaning member to move via the clearance groove.

[0007] In some embodiments, the cleaning member includes a supporting member, a rejecting member, and a combing member; Both ends of the support member are connected to the transmission member via the clearance groove; The rejecting member is arranged on the supporting member, and the rejecting member is used to scrape the upper surface of the carrier plate; The comb-like member is disposed on the side of the support member away from the collection mechanism. There is a gap between the comb-like member and the removal member. The comb-like member is used to remove feces in the cat litter.

[0008] In some embodiments, the removal member and the comb-like member are rotatably mounted on the support member. The sides of the removal member and the comb-like member close to the carrier plate can swing towards the collection mechanism. The cleaning member further includes an elastic member. The elastic member can cause the removal member and the comb-like member to swing away from the collection mechanism and point to the carrier plate.

[0009] In some embodiments, the transmission member includes a power member and a conveying member. The power member is used to provide driving force. The support member is mounted on the conveying member. The power member drives the support member to reciprocate through the conveying member.

[0010] In some embodiments, the collection mechanism includes a discharge port, a material receiving device, and a collection device. The discharge port is opened on one side of the basin body. The discharge port is used for discharging feces. The material receiving device is disposed outside the basin body. The material receiving device can receive the excess cat litter discharged from the discharge port. The collection device is used to collect the feces discharged from the discharge port.

[0011] In some embodiments, the material receiving device includes a lifting member, a material receiving box, and a controller. The material receiving box is disposed outside the basin body and on one side of the discharge port. The upper end of the material receiving box is open. The lifting member is used to lift and lower the material receiving box. After the material receiving box rises, the collected cat litter can be poured onto the carrier plate. The controller can control the rising or falling of the lifting member. When the cleaning mechanism moves towards the collection mechanism, the controller controls the lifting member to lower. The lifting member positions the material receiving box below the discharge port to receive cat litter. When the cleaning mechanism moves away from the collection mechanism and the cleaning mechanism is separated from the discharge port, the lifting member causes the material receiving box to rise.

[0012] In some embodiments, the material receiving device further includes a baffle. The baffle is disposed in the material receiving box. The baffle restricts the cat litter in the material receiving box from moving out. After the baffle descends with the material receiving box, the baffle restricts the cat litter in the material receiving box from moving out; after the baffle ascends with the material receiving box, the baffle releases the restriction, and the cat litter in the material receiving box moves onto the carrier plate in the basin body.

[0013] In some embodiments, the collection device includes a grid plate rotatable outside the basin body and a collection box; When the material receiving box is located below the discharge port, the grid plate rotates to the upper side of the material receiving box to pick up feces; when the material receiving box moves upward, the material receiving box swings the grid plate, causing the feces on the grid plate to roll into the collection box for collection.

[0014] In some embodiments, the cat litter basin further includes a humidity sensor and a delay controller; The humidity sensor is disposed on the carrier plate for detecting the dryness and wetness of feces; The delay controller is used to control the speed of starting the cleaning mechanism according to the detection result of the humidity sensor.

[0015] The beneficial effects of the present invention are as follows: After the sensor receives that the cat leaves the basin body, the sensor triggers the cleaning device to work. The cleaning device cleans the feces in a translational manner and pushes them to the collection mechanism for collection. It can not only achieve self-cleaning in a flat-pushing manner but also solve the problem of dispersing the agglomerated cat litter by flipping. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

Among them, the x - axis arrow direction is the "right" direction in the following text, the y - axis arrow direction is the "up" direction in the following text, and the z - axis arrow direction is the "back" direction in the following text. In the actual application of the present application, it is not limited thereto.

[0021] Such as Figures 1 - 3As shown, this embodiment provides a cat litter box, which includes a basin body 110, a carrier plate 120, a cleaning mechanism 130, a collecting mechanism 140, and a sensor; the carrier plate 120 is arranged in the basin body 110 for carrying cat litter; the cleaning mechanism 130 can be translated in the basin body 110 for cleaning the cat litter; the collecting mechanism 140 is arranged on the side of the basin body 110 for collecting feces cleaned by the cleaning mechanism 130; the sensor is used to sense the cat going out of the basin body 110, and each time the cat goes out of the basin body 110, the sensor controls the cleaning mechanism 130 to clean it once. That is, the cat litter is poured onto the carrier plate 120 in the basin body 110 and spread flat, and when the sensor receives that the cat has left the basin body 110, the sensor triggers the cleaning device to work, and the cleaning device cleans the feces in a translational manner and pushes it to the collecting mechanism 140 for collection, which can not only realize self-cleaning in a translational manner, but also solve the problem of flipping the cat litter to disperse the lumps.

[0022] Preferably, the sensor can be a pressure sensor, and the signal control of the sensor can be achieved according to the weight change of the cat standing in the basin 110.

[0023] like Figures 2 - 3 As shown, in this embodiment, the cleaning mechanism 130 includes a cleaning member 131, a transmission member 132, and a clearance groove 111 arranged on both sides of the basin body 110; the cleaning member 131 is arranged in the basin body 110 and located on the upper side of the carrier 120, and the cleaning member 131 is used to clean the cat litter; the transmission member 132 drives the cleaning member 131 to move through the clearance groove 111. The cleaning member 131 slides in the clearance grooves 111 on both sides, that is, the cleaning device cleans the feces in the entire cat litter box 100, without the need to locate the feces position through an extra positioning system, and the feces cleaning is completed at one time.

[0024] In some embodiments, a curtain is provided in the basin body 110 , and the curtain is located inside the make way slot 111 . The curtain can block the make way slot 111 to prevent cat litter from entering the make way slot 111 , and the curtain does not block the movement of the cleaning member 131 .

[0025] like Figure 3 , Figure 10As shown, in this embodiment, the cleaning member 131 includes a support member 131a, a removal member 131b, and a comb member 131c; both ends of the support member 131a are connected to the transmission member 132 through the relief groove 111; the removal member 131b is disposed on the support member 131a, and the removal member 131b is used to scrape the upper surface of the carrier plate 120; the comb member 131c is disposed on one side of the support member 131a away from the collection mechanism 140, and there is a gap between the comb member 131c and the removal member 131b, and the comb member 131c is used to pick out the feces in the cat litter. By arranging the comb member 131c on the side of the removal member 131b away from the collection mechanism 140 and having a gap between the comb member 131c and the removal member 131b, when cleaning the feces, the feces on the carrier plate 120 can be completely scraped off first and then pushed by the comb member 131c, preventing the problem that the lumps are scattered without being scraped. And by adopting the comb-shaped setting, the comb will not take away the clean cat litter.

[0026] In some embodiments, the teeth of the comb plate face downward, and the interval between adjacent tooth gaps of the comb plate is between 4-7 mm.

[0027] In some embodiments, the length of the teeth of the comb plate is between 12-15 cm.

[0028] In some embodiments, the removal member 131b is a rigid plastic plate; the cross-section of the lower end of the removal member 131b is conical, the angle between the lower side of the removal member 131b and the carrier plate 120 is between 15-30 degrees, and the lower end of the removal member 131b points to the collection mechanism 140. The interval between the removal member 131b and the support member 131a is in a hollow shape to prevent dispersion caused by obstruction due to incomplete scraping.

[0029] As Figure 3As shown, in this embodiment, the removing member 131b and the comb member 131c are rotatably mounted on the support member 131a. The sides of the removing member 131b and the comb member 131c close to the carrier plate 120 can swing towards the collecting mechanism 140; the cleaning member 131 further includes an elastic member; the elastic member can make the removing member 131b and the comb member 131c swing away from the collecting mechanism 140 and point to the carrier plate 120. By rotatably mounting the removing member 131b and the comb member 131c on the support member 131a, when away from the collecting mechanism 140, blocked by the cat litter, the lower sides of the removing member 131b and the comb member 131c swing towards the side of the collecting mechanism 140, moving them to the surface of the cat litter, preventing pushing the cat litter, and after swinging, since they are on the surface of the cat litter, they can smooth the cat litter, preventing the problem of uneven cat litter after multiple uses. With the arrangement of the elastic member, it can provide a force for the lower sides of the removing member 131b and the comb member 131c to swing away from the collecting mechanism 140, and the swinging force has a certain effect of smoothing the cat litter; at the same time, when the removing member 131b and the comb member 131c move towards the collecting mechanism 140, the removing member 131b and the comb member 131c can point to the carrier plate 120 for normal scraping and removing operations.

[0030] In this embodiment, the transmission member 132 includes a power member 132a and a conveying member 132b; the power member 132a is used to provide the transmission power; the support member 131a is mounted on the conveying member 132b; the power member 132a drives the support member 131a to reciprocate through the conveying member 132b.

[0031] In some embodiments, there are two groups of the conveying members 132b, which are respectively arranged on both sides outside the basin body 110 and on one side of a corresponding relief groove 111. The two groups of the conveying members 132b drive the support member 131a to move simultaneously, making the removal of feces more stable.

[0032] Preferably, the conveying member 132b can be composed of a pulley and a belt; the support member 131a is fixed on the belt, and the power member 132a drives the belt to rotate through the pulley.

[0033] Preferably, the conveying member 132b can be composed of a sprocket and a chain; the support member 131a is fixed on the chain, and the power member 132a drives the chain to rotate through the sprocket.

[0034] In some embodiments, the power member 132a can adopt a forward and reverse motor.

[0035] Preferably, the forward and reverse motor is a three-phase asynchronous motor.

[0036] Such as Figures 2 - 5As shown, in this embodiment, the collection mechanism 140 includes a discharge port 112, a material receiving device 141, and a collection device 142. The discharge port 112 is opened on one side of the basin body 110 and is used for discharging feces. The material receiving device 141 is arranged outside the basin body 110 and can receive the excess cat litter discharged from the discharge port 112. The collection device 142 is used to collect the feces discharged from the discharge port 112. Using the material receiving device 141 can move the cat litter taken away back into the basin body 110, preventing the cat litter near the collection mechanism 140 from becoming thin after being taken away each time during cleaning, which affects the use effect. Through the combined use of the material receiving device 141 and the collection device 142, the separation of feces is effectively achieved.

[0037] As Figure 2 , Figures 4 - 5 and Figures 8 - 9 As shown, in this embodiment, the material receiving device 141 includes a lifting member 141a, a material receiving box 141b, and a controller. The material receiving box 141b is arranged outside the basin body 110 and on one side of the discharge port 112, and the upper end of the material receiving box 141b is open. The lifting member 141a is used to lift and lower the material receiving box 141b. After the material receiving box 141b rises, the collected cat litter can be poured onto the carrier plate 120. The controller can control the rise or fall of the lifting member 141a. When the cleaning mechanism 130 moves towards the collection mechanism 140, the controller controls the lifting member 141a to lower, and the lifting member 141a positions the material receiving box 141b below the discharge port 112 for receiving cat litter. When the cleaning mechanism 130 moves away from the collection mechanism 140 and the cleaning mechanism 130 is separated from the discharge port 112, the lifting member 141a raises the material receiving box 141b. By lowering the material receiving box 141b to receive materials and raising it to pour materials, the operation is simple and convenient. Using the controller to control the rise and fall according to the moving position of the cleaning mechanism 130 effectively avoids the problems of missed receiving or cat litter spilling.

[0038] In some embodiments, the lifting member 141a includes a multi-stage electric cylinder, that is, an electric cylinder composed of multiple cylinder barrels, which can achieve a longer distance of pushing to ensure that the material receiving box 141b can be pushed to a specified position.

[0039] In some embodiments, the lifting member 141a includes a lead screw and a nut. The nut is fixed to the material receiving box 141b, and the rotation of the lead screw drives the nut to move up and down, thereby driving the material receiving box 141b to move up and down.

[0040] In some embodiments, the lifting member 141a can also be implemented by means of a transmission wheel and a conveyor belt, that is, the rotation of the transmission wheel drives the conveyor belt to move, thereby driving the material receiving box 141b to move up and down.

[0041] As Figures 4 - 7In some embodiments, a baffle 144 is provided on the litter box 100. The baffle 144 is located at the discharge opening 112. When the cleaning member 131 is not moved to the discharge opening 112, the baffle 144 blocks the discharge opening 112. When the cleaning member 131 is moved to the discharge opening 112, the cleaning member 131 pushes the baffle 144 to separate from the discharge opening 112, and the discharge opening 112 is opened.

[0042] In some embodiments, the litter box 100 further includes an elastic member, and the elastic member can push the baffle 144 to block the discharge opening 112. That is, when the cleaning member 131 moves out of the discharge opening 112, the elastic member pushes the baffle 144 to block the discharge opening 112.

[0043] As Figures 4 - 5 and Figures 8 - 9 As shown, in this embodiment, the material receiving device 141 further includes a baffle 143. The baffle 143 is provided in the material receiving box 141b, and the baffle 143 restricts the cat litter in the material receiving box 141b from moving out; when the baffle 143 descends with the material receiving box 141b, the baffle 143 restricts the cat litter in the material receiving box 141b from moving out; when the baffle 143 ascends with the material receiving box 141b, the baffle 143 releases the restriction, and the cat litter in the material receiving box 141b moves onto the carrier plate 120 in the basin body 110. That is, a baffle 143 is installed on the side of the material receiving box 141b close to the basin body 110. When the material receiving box 141b moves upward, the baffle 143 opens, and the cat litter in the baffle 143 and the material receiving box 141b can slide into the basin body 110.

[0044] In some embodiments, the upper side of the baffle 143 is hinged, and the self-weight of the baffle 143 blocks the lower side of the baffle 143 from opening. A stopper is provided on the baffle 143, and a limit block is provided on the basin body 110. When the limit block contacts the stopper, the limit block opens the lower side of the baffle 143 through the stopper.

[0045] In some embodiments, the bottom in the material receiving box 141b is an inclined surface, and the side of the inclined surface close to the basin body 110 is lower than the side far from the basin body 110.

[0046] As shown in FIG. 3 and Figures 8 - 9As shown, in this embodiment, the collection device 142 includes a grid plate 142a rotatable outside the basin body 110 and a collection box 142b. When the receiving box 141b is located below the discharge port 112, the grid plate 142a rotates to the upper side of the receiving box 141b to pick up feces. When the receiving box 141b moves upward, the receiving box 141b causes the grid plate 142a to swing, so that the feces on the grid plate 142a roll into the collection box 142b for collection. That is, one side of the grid plate 142a away from the basin body 110 is hinged. When the receiving box 141b moves upward, the grid plate 142a rotates around the hinge, and during the rotation, the feces on the grid plate 142a are poured into the collection box 142b for collection. The collection of feces can be completed only by moving the receiving box 141b up and down, which is convenient to operate and does not require an external power source. And when the receiving box 141b moves downward, the grid plate 142a swings downward under its own weight to separate feces again.

[0047] In some embodiments, the collection box 142b and the grid plate 142a may be provided with partition plates. The upper side of the partition plate is hinged, and the lower side of the partition plate swings under force, which can isolate the feces smell after the feces are collected and prevent the odor from spreading.

[0048] In some embodiments, the cat litter box 100 further includes a humidity sensor and a delay controller. The humidity sensor is arranged on the carrier plate 120 to detect the dryness and wetness of the feces. The delay controller is used to control the start speed of the cleaning mechanism 130 according to the detection result of the humidity sensor. The humidity sensor is used to detect the humidity of the cat litter on the carrier plate 120, and then judge whether the feces are dry or wet. When they are dry, the delay controller does not delay, and directly controls the cleaning mechanism 130 to work until a cleaning is completed. When they are wet, the delay controller delays, that is, controls the cleaning mechanism 130 not to work immediately, but postpones the work of the cleaning mechanism 130. The postponement time can be 20 - 60 minutes, that is, to make the wet cat litter form lumps, and then the cleaning mechanism 130 works to complete a cleaning. By controlling the cleaning time according to the dryness and wetness, it can prevent the wet cat litter from spreading when it is cleaned before forming lumps, and also prevent the dry feces from not being cleaned in time, resulting in the spread of odor and affecting the air.

[0049] In some embodiments, the sensor is in series control with the humidity sensor and the delay controller, that is, the cleaning mechanism 130 can be controlled only when the conditions are met at the same time. That is, after the sensor senses the departure of the cat, it feeds back to the delay controller under the detection of the humidity sensor, and controls whether the cleaning mechanism 130 starts working immediately according to the dry and wet feces.

[0050] In some embodiments, a stopper 150 is provided on the basin body 110. The stopper 150 supports the carrier plate 120 within the basin body 110. After the stopper 150 is removed, the carrier plate 120 can be separated from the basin body 110, facilitating the removal of the cat litter on the carrier plate 120 and the subsequent cleaning of the carrier plate 120.

[0051] In some embodiments, a hole groove is formed on the basin body 110, and a box body 160 is installed in the hole groove. The hole groove is located below the carrier plate 120, that is, the box body 160 is located below the basin body 110. After the stopper 150 is removed, the carrier plate 120 can fall into the box body 160, enabling the box body 160 to collect the used cat litter for centralized treatment.

[0052] In some embodiments, a counter can also be provided on the basin body 110 to count the number of times the cleaning member 131 operates, facilitating the cleaning of the feces in the collection box 142b and the replacement of the cat litter according to the count.

[0053] Before pouring the cat litter, the carrier plate 120 is placed into the basin body 110 and supported by the stopper 150. The cleaning member 131 is located on one side of the basin body 110 away from the collection mechanism 140, and the receiving box 141b is located below the discharge port 112.

[0054] As shown in Figure 4- Figure 9 As shown, when cleaning the feces, the cleaning member 131 moves towards the collection mechanism 140 under the action of the transmission member 132 until the feces are pushed out of the discharge port 112. The cleaning member 131 stops moving further towards the collection mechanism 140 and then moves away from the collection mechanism 140 again. After the cleaning member 131 is separated from the discharge port 112, the lifting member 141a is activated to drive the receiving box 141b to rise. After the rising is completed, it slowly descends again to the lower side of the discharge port 112. Due to the slow descent, it does not block the cat litter from moving out of the receiving box 141b. Finally, the cleaning member 131 returns to the side away from the collection mechanism 140, thus completing one cleaning of the feces.

[0055] In summary, the present invention provides a cat litter basin. After the sensor receives that the cat has left the basin body, the sensor triggers the cleaning device to operate. The cleaning device cleans the feces in a translational manner and pushes them to the collection mechanism for collection. It can achieve self-cleaning in a flat-pushing manner and solve the problem of flipping the cat litter to disperse the lumps.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
