Description

Technical Field

[0001] This application relates to a pet cleaning device, specifically a beaded odor-proof cat feces collection device and its corresponding operating method. Background Technology

[0002] Currently, most cat owners use clump-type cat litter to collect cat feces. The conventional method is to manually sift out the feces with a litter scoop and then discard it. This method has obvious drawbacks: manual operation is cumbersome, easily attracts odors, and has low cleaning efficiency; odors can easily spread during the transfer and disposal of feces, polluting the indoor environment; in the document with publication number CN120787824A, the feces are not independently separated, and contact between feces exacerbates odor leakage, and they are also prone to scattering when poured, affecting environmental hygiene. Existing automatic cat litter boxes mostly only achieve the function of separating feces from cat litter, lacking a subsequent odor-preventing binding structure after each use, still failing to solve the odor leakage problem and failing to meet users' core needs for convenient and efficient odor-preventing feces collection. Summary of the Invention

[0003] In response to the shortcomings of existing cat feces collection methods, such as easy leakage of odors, cumbersome operation, and lack of separation and mixing of feces clumps, this application provides a beaded odor-proof cat feces collection device and operation method, which realizes automatic separation of feces clumps and cat litter, independent bundling and sealing, and orderly beaded storage, completely eliminating odor leakage and protecting environmental hygiene.

[0004] The technical solution adopted by this application to solve the above problems includes: a beaded odor-proof cat feces collection device, comprising a base, a controller, a sensor, and a binding mechanism. The base is provided with a cat feces conveying device that outputs clumps of cat feces by rotation. The sensor is installed on the cat feces conveying device, and the binding mechanism is used to bind the collection bag containing clumps of cat feces. The base includes a chamber and a support, with the chamber rotatably mounted on the support. The cat feces conveying device includes a chamber, a drive assembly, an electric door, and a cat feces channel. The drive assembly is connected to the chamber and controls its rotation. A filter screen is provided on the chamber, and an electric door is provided on the chamber corresponding to the filter screen. The filter screen has a filter sand structure, where the maximum size of the cat litter is less than the gap between the filter sand structures and the minimum size of the clumps of cat feces. One side of the filter screen is fixedly installed on the chamber and fits against the cylindrical inner wall of the chamber. In the defecation state, one side of the filter screen corresponds to the inlet of the cat feces channel, and the collection bag is fitted onto the outlet of the cat feces channel. The controller is connected to the sensor, the binding mechanism, the drive assembly, and the electric door. This application achieves automatic separation of cat feces clumps and cat litter through rotation, and achieves independent binding and sealing through a binding mechanism to prevent odor leakage and protect environmental hygiene.

[0005] The strapping mechanism described in this application is mounted on a support via a strapping mechanism lifting motor, which enables automatic pulling down of the waste collection bag, thereby allowing for segmented sealing, saving materials, and improving utilization and automation.

[0006] The feces collection bag is stacked and fitted onto the cat feces channel outlet via a feces collection bag box. In the initial state, the lower part of the feces collection bag protrudes from the feces collection bag box. The vertical distance between the bottom seal of the feces collection bag and the tightening motor of the strapping mechanism is greater than the vertical distance required to load one cat feces (i.e., it must be greater than the distance between adjacent separation sections. When strapping, the distance between the tightening motor of the strapping mechanism and the previous seal of the feces collection bag will be slightly reduced).

[0007] The angle between the defecation state of the filter screen and the horizontal plane is between 120 and 160°.

[0008] The filter structure is a filter screen with a pore size between 8-15mm.

[0009] This application may also include a recycling bin, which is installed on the support and located below the cat litter passage outlet.

[0010] The waste collection bag is made of odor-proof material. The upper end of the waste collection bag is fitted onto the cat's waste passage outlet with an elastic drawstring and is located inside the waste collection bag box to prevent odor from leaking out from the interface.

[0011] This application also includes a storage door, which is attached to the storage body.

[0012] The technical solution adopted in this application to solve the above problems also includes the operation method of the above-mentioned beaded odor-proof cat feces collection device, including the following steps: S0: Controller initialization, set cleaning time, set the strapping count of the strapping mechanism to 1, set the total number of strapping times N and the distance between adjacent separation sections, and each mechanism is in the initial state; S1: The cat defecates in the area of ​​the cage where there is clumping cat litter, and the cat litter wraps the feces to form clumping cat feces; S2: After the set cleaning time is reached, the controller controls the drive component to rotate the chamber. The filter screen rotates from bottom to top to the defecation position. The controller opens the electric door, and the clump of cat feces enters the collection bag through the cat feces channel. The sensor detects the clump of cat feces falling in and sends a signal to the controller. S3: The controller waits for the set time for the cat to fall in one cluster; S4: The controller controls the closing motor of the strapping mechanism to complete the strapping at the current strapping position, forming the current sealed separation section, and limiting the clump of cat feces below the current sealed separation section; S5: The controller controls the lifting motor of the strapping mechanism to work, and the shrinking motor of the strapping mechanism drives the collection bag to pull down to extend the distance between adjacent separation sections. S6: The strapping mechanism's narrowing motor releases the waste collection bag, the strapping mechanism's lifting motor drives the strapping mechanism to reset, and the drive component drives the compartment to reset. S7: The binding count of the binding mechanism is incremented by 1; if the binding count exceeds the total number of bindings N of the stool bag, binding is completed and proceed to step S8; otherwise, wait for the set cleaning interval and proceed to step S2. S8: Remove the stool bag box, put on the new stool bag box, and pull out the bottom of the stool bag that is exposed at the bottom of the new stool bag box to create the distance between the adjacent separation sections.

[0013] As a special case, the distance between adjacent separation segments is 8 to 15 centimeters.

[0014] This application repeats steps S2-S6 N times. Each time a new fecal mass falls above the current sealing section and is tied up, the fecal collection bag forms a bead-like independent storage pattern, with no odor leakage and high utilization rate.

[0015] Compared with the prior art, this application has the following advantages and effects: excellent odor prevention effect: each fecal clump is independently sealed, and the beaded structure avoids contact between fecal clumps, blocking odor leakage from the source and ensuring a fresh indoor environment; Easy to operate: No need for manual sand shoveling and sifting; filtering, collecting feces, and bundling can be completed automatically, reducing the difficulty of cleaning for cat owners; Organized storage: The beaded independent compartments prevent items from scattering when discarded, and allow for segmented retrieval and disposal, offering high flexibility.

Detailed Implementation

[0024] The application will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are explanations of this application, but the present invention is not limited to the following embodiments. Figure 1 The left side is the front, and the right side is the back.

[0025] See Figures 1-7 The beaded cat feces collection device in this embodiment includes a base 1, a controller, a cat feces channel 2, a sensor 3, a binding mechanism 4, a feces collection bag box 6, and a drive assembly 7. The base 1 includes a chamber 11, a rotating shaft 12, a filter screen 13, and a support 14. The rotating shaft 12 is fixedly connected to the chamber 11. The chamber 11 is equipped with an electric door 112 for defecation. The filter screen 13 is installed inside the chamber 11. One side of the chamber 11 ( Figure 6 On the right side, a cat litter passage 2 is provided. The cat litter passage 2 is mounted on the support 14 and corresponds to the electric gate 112 during the defecation state. It is used to discharge clumps of cat feces. The chamber 11 is connected to the drive assembly 7 via a rotating shaft 12 and can rotate. The drive assembly 7 (located at the rear of the chamber 1) is mounted on the support 1. The drive assembly 7 includes a motor 71 and a motor shaft 72. The motor shaft 72 is connected to the rotating shaft 12 to control the rotation of the cylindrical chamber 11. A filter screen 13 is used to separate cat litter and clumps of cat feces, and then the clumps of cat feces are discharged through the electric gate 112 and the cat litter passage 2. The filter screen 13 is equipped with a sand filter structure 131. The maximum size of the cat litter (the maximum distance between any two points on the outer surface of a single cat litter) is less than the gap in the sand filter structure (the width or aperture of the slits that allow cat litter to pass through) and less than the minimum size of the clump of cat feces (the angle of the clump of cat feces is greater than the gap in the sand filter structure, preventing it from passing through). This allows cat litter to fall from the sand filter structure 131 during the conveying process, while the clump of cat feces (cat feces wrapped in cat litter, the same below) is discharged from the cat feces channel 2. The filter screen 13 is fixedly installed on one side of the chamber 11, and the initial position of the filter screen 13 is located at... Figure 5The upper left position, designed to minimize obstruction of the cat's entry and exit, rotates with the chamber 11, first from bottom to top. The cat litter passes through the filter structure 131, while clumps of feces move with the filter, separating the cat litter from the clumps. Figure 5 , Figure 6 (The rotation is counter-clockwise) and then rotates to... Figure 6 In the defecation state shown, one side of the filter screen 13 corresponds exactly to the cat litter channel inlet 21. At this time, the electric door 112 is open, and the filter screen 13 forms an angle θ relative to the horizontal plane, with the angle θ being between 120 and 160°. This facilitates the rolling of clumped cat litter outwards into the cat litter channel 2, while unclumped cat litter can pass through the filter screen 131 and fall to the bottom of the chamber 11. As a special case, the filter screen 131 is a filter mesh with a pore size between 8 and 15 mm, allowing only cat litter particles smaller than the filter structure 131 to pass through. Unclumped cat litter falls back to the bottom of the chamber 11 for recycling.

[0026] This application also includes a waste collection bag box 6, which contains a stacked waste collection bag 60. In the initial state, the lower part of the waste collection bag 60 is located under the waste collection bag box 6. The vertical distance between the bottom seal 601 of the waste collection bag 60 and the tie-down mechanism motor 41 is greater than the vertical distance required to load one cat feces (i.e., ensuring that the tie-down seal is above the cat feces collected once). The stacked waste collection bag 60 can be pulled out section by section by pulling down. The existing binding mechanism 4 is used to bind the feces bag 60 in the feces bag box 6. The binding mechanism 4 is equipped with a binding mechanism shrinking motor 41, which binds the feces bag 60 after shrinking its opening. The feces bag box 6 is connected to the cat feces channel outlet 22. When a cat feces clump falls into the feces bag 60 and accumulates at the current bottom of the feces bag 60, the binding mechanism 4 can bind it above the current location of the clump of cat feces to prevent the backflow and diffusion of the feces odor. Then, the controller controls the binding mechanism 4 to pull down a section of the feces bag 60. The bound part falls into the lower recycling bin, and can wait for the next clump of cat feces to enter before binding it again, making full use of the feces bag capacity and improving the utilization rate of the feces bag, until the binding mechanism 4 binds the last section of the feces bag (the last sealing section).

[0027] The binding mechanism 4 is mounted on the support 14 or the collection bin 5 via a binding mechanism lifting motor 42. The binding and shrinking structure is positioned corresponding to the binding mechanism shrinking motor 41. After completing one binding action, the binding mechanism lifting motor 42 pulls the collection bag 60 downwards a certain distance, and the bound portion falls into the collection bin below. The binding mechanism lifting motor 42 then resets to its initial position, waiting for the next trigger signal from the sensor 3. The distance between the sealing and separating sections (the distance between adjacent separating sections, i.e., the length of the collection bag pulled out by the binding mechanism 4 each time) between two binding actions is 8-15cm, suitable for the storage space of single-clump cat feces. An alarm is triggered when the last section of the collection bag (the last sealing section) is bound or when the collection bag is obstructed during pulling, requiring the collection bag box 6 to be replaced. The binding mechanism 4 can use heat sealing, buckle binding, or compression sealing binding methods. In this embodiment, a snap-on sealing method is adopted. This method uses a pressure sealing mechanism, which includes a concave and convex pressure mold. The snap pin is pressed out by pressure to fasten the stool bag and form a sealed separation. This mechanism is existing technology and will not be described in detail here.

[0028] This application may also include a recycling bin 5, located below the exit of the cat litter passage 2, for temporarily storing bundled feces bags.

[0029] Sensor 3 can be a photoelectric sensor, which is installed at the end (exit) of the cat litter passage 2 to detect the passage signal of feces. In this embodiment, the controller receives the sensor 3 and the response time is ≤0.5s, which can quickly trigger the binding mechanism 4.

[0030] The controller of the prior art is electrically connected to the sensor 3, the strapping mechanism 4 (including the strapping mechanism shrinking motor 41 and the strapping mechanism lifting motor 42) and the drive component 7 respectively. It can receive the signal from the sensor 3, control the action of the strapping mechanism 4 and / or the drive component 7, and can also be adapted to set the waiting time for one clump of cat feces to fall (the delay time from receiving the clump of cat feces signal from the sensor 3 to the completion of one clump of cat feces falling and the formal start of one strapping action).

[0031] The stool collection bag is made of odor-proof material, using coated non-woven fabric, PE odor-proof film, or EVA odor-proof film. The opening end of the stool collection bag ( Figure 7 The upper part is located inside the feces bag box 6, and the feces bag box sleeve 6 is located at the outlet of the cat feces channel 2 to prevent odor from leaking from the interface.

[0032] The operation method of the beaded cat feces collection device in this embodiment includes the following: S0: Controller initialization, setting the cleaning time, and setting the strapping count of strapping mechanism 4 to 1 (initial strapping count, see...). Figure 7 The total number of bundling times N and the spacing between adjacent separation sections are set, and each mechanism is in its initial state (the drive component 7 makes the filter screen 13 of the chamber 11 located in the initial state). Figure 5In the current state, the electric door 112 is closed, the strapping mechanism's closing motor 41 releases the waste bag, and the strapping mechanism's lifting motor 42 is in the position... Figure 3 (See the location for bundling and sealing). S1: The cat defecates in the area of ​​compartment 11 where there is clumping cat litter. The cat litter wraps the feces to form clumping cat feces with a particle size usually greater than 15mm. S2: After the set cleaning time is reached, the controller controls the drive component 7 to drive the chamber 11 to rotate. The filter screen 131 rotates from bottom to top to the defecation position. The controller opens the electric door 112. The clump of cat feces enters the collection bag 60 through the cat feces channel 2. The sensor detects the clump of cat feces falling in and sends a signal to the controller. S3: The controller waits for the set time for the cat to fall in one cluster; S4: The controller controls the strapping mechanism shrinking motor 41 to complete the strapping at the current strapping position, forming the current sealed separation section, and limiting the clump of cat feces below the current sealed separation section; S5: The controller controls the lifting motor 42 of the strapping mechanism to work, which in turn drives the collection bag to pull down the adjacent separation section spacing via the narrowing motor 41 of the strapping mechanism. S6: The strapping mechanism shrinking motor 41 releases the collection bag, the strapping mechanism lifting motor 42 drives the strapping mechanism 4 to reset, and the drive component 7 drives the compartment 11 to reset. S7: The binding count of the binding mechanism 4 is incremented by 1; if the binding count exceeds the total number of bindings N (the last sealing section N) of the stool bag, binding is completed and proceeds to S8; otherwise, wait for the set stool cleaning interval (usually the interval between one stool cleaning) and then proceed to S2. S8: Remove the stool bag box, put on the new stool bag box, and pull out the bottom of the stool bag that is exposed at the bottom of the new stool bag box to create the distance between the adjacent separation sections.

[0033] This application repeats steps S2-S6 N times. Each time a new fecal mass falls above the current sealing section, it is tied up. The fecal collection bag 60 forms a beaded independent storage form, with no odor leakage and high utilization rate.

[0034] This application allows you to set the specific time for performing step S2 according to your cat's lifestyle, such as every morning or at intervals.

[0035] Specifically, during use, after the cat's feces clump together, the controller activates the drive component 7 to rotate the filter screen 131 on the chamber 11 from bottom to top, gradually separating the feces from the cat litter. The feces fall into the collection bag 60 through the cat feces channel 2. The sensor 3 detects this and sends a signal to the controller, which then triggers the binding mechanism 4 in a timely manner to form a sealed separation section that locks in the feces. Subsequent feces fall in sequentially and are sealed section by section. The collection bag 60 is stored in a beaded manner, which is odor-proof, highly efficient, and saves materials.
