Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a self-cleaning pet toilet and excrement collection system. Background Technology

[0002] With the improvement of living standards, more and more families are choosing to keep pets, such as cats. Cats are naturally clean animals and have the habit of relieving themselves in clean litter boxes, which requires owners to clean their excrement frequently to maintain a hygienic environment. Self-cleaning litter boxes, also known as smart litter boxes or automatic litter boxes, are a type of excretion assistance product designed specifically for cats. Simply fill the box with litter to use it. However, current smart litter boxes on the market still have some issues that need improvement: 1. Insufficient ability to handle soft stools: After a cat defecates, these litter boxes cannot effectively separate and expel the feces through filtration; 2. Difficulty in solving the problem of clumped litter sticking to the bottom: Once the litter clumps and sticks to the bottom of the box, it still needs to be manually scooped by the owner; 3. Poor odor control: The separated excrement is temporarily stored in the accompanying trash can, which can easily produce a pungent odor over time, thus affecting indoor air quality.

[0003] Therefore, it is essential to provide a self-cleaning pet toilet and excrement collection system to address the shortcomings of existing technologies. Utility Model Content

[0029] The second objective of this invention is to overcome the shortcomings of existing technologies and provide an excrement collection system. This excrement collection system can automatically separate excrement, transport it to the outside, collect it into a bag and seal it, and prevent the odor of the excrement from escaping from the inside of the bag during bagging.

[0030] The above-mentioned objectives of this utility model are achieved through the following technical measures: An excrement collection system is provided, which includes the aforementioned self-cleaning pet toilet and an odor-preventing collection mechanism, wherein the odor-preventing collection mechanism is located at the excrement outlet of the self-cleaning pet toilet.

[0032] During cleaning, the first sealing mechanism drives the bag opening to open, and the second sealing mechanism drives the middle of the bag to seal, thereby allowing the excrement from the self-cleaning pet toilet to enter the bag. After the excrement enters the bag, the first sealing mechanism drives the bag opening to seal, and the second sealing mechanism drives the middle of the bag to open, thereby allowing the excrement to enter the bottom of the bag.

[0033] This invention relates to a self-cleaning pet toilet and excrement collection system.

Detailed Implementation

[0050] The technical solution of this utility model will be further explained with reference to the following embodiments.

[0051] Example 1 A self-cleaning pet toilet, such as Figures 1 to 4 As shown, the following settings are included: Main body 100 – Adsorbent 700 used to hold and absorb excrement 600; The filtration and conveying mechanism 200 is movably mounted on the main body 100 and is used to filter the clumped excrement 600 by moving it upward and to convey the excrement 600 out of the self-cleaning pet toilet by winding it up. The first drive mechanism 300 is fixedly assembled in the main body 100 and connected to the filter and conveying mechanism 200 for driving the filter and conveying mechanism 200 to rise and fall inside the main body 100. The second drive mechanism 400 is connected to the main body 100 and is used to drive the main body 100 to rotate back and forth, so as to shift the adsorbent 700 and provide a reset space for the filtration and conveying mechanism 200.

[0052] This embodiment uses a cat litter box as an example, and the absorbent 700 is cat litter. When the self-cleaning pet litter box is in operation, the ground direction is defined as the bottom of the self-cleaning pet litter box, and at this time, the storage compartment 111 of the cylinder 110 is parallel to the ground direction. Moreover, the filtration and conveying mechanism 200 rises, causing the unclumped absorbent 700 to fall through the gaps in the filter screen 210, while the clumped absorbent 700 and excrement 600 remain on the filter screen 210 of the filtration and conveying mechanism 200. There is no additional vibration in this process, which is especially suitable for easily broken soft stools, avoiding the problems of traditional cat litter boxes where soft stools cannot be filtered and clumps stick to the bottom, requiring manual shoveling.

[0053] like Figure 3 and Figure 4 As shown, the main body 100 includes a cylinder 110, two fixing plates 120, and multiple pairs of bristles (not shown) for preventing leakage of the adsorbent 700. The two fixing plates 120 are fixedly mounted on the open ends of the cylinder 110 on both sides. The filtering and conveying mechanism 200 is movably disposed inside the cylinder 110. The first drive mechanism 300 is assembled with the fixing plates 120. Each pair of bristles is fixedly mounted on both sides of a clearance slot 121. Each fixing plate 120 is provided with multiple clearance slots 121 for the filtering and conveying mechanism 200 to pass through. At least one fixing plate 120 and the cylinder 110 are provided with an inlet / outlet channel 122 for the filtering and conveying mechanism 200 to enter and exit. The inlet / outlet channel 122 is located at the upper end of the main body 100.

[0054] It should be noted that the function of the inlet / outlet channel 122 is to provide movement space for the filter screen 210. Since the filtration and conveying mechanism 200 needs to convey the excrement 600 by winding it up, the filter screen 210 needs to be moved to the outside of the cylinder 110, and the inlet / outlet channel 122 can meet this movement requirement. In this utility model, the function of the fixing plate 120 is to form a relatively closed space in the cylinder 110 to prevent the adsorbent 700 from spilling out, and also to provide a fixed position for the first drive mechanism 300. The function of the snap strip in this utility model is to seal the clearance seam 121, and at the same time, to allow the connecting wire 220 of the filtration and conveying mechanism 200 to pass through.

[0055] like Figure 6 As shown, the cylinder 110 is provided with a storage chamber 111 for storing the adsorbent 700, a first temporary chamber 112 for temporarily accommodating the adsorbent 700 to provide reset space for the filtration and conveying mechanism 200, and an inlet / outlet 113 for pets to enter and exit. The first temporary chamber 112 and the storage chamber 111 are both located inside the cylinder 110, and the first temporary chamber 112 is located on one side of the storage chamber 111. The inlet / outlet 113 is opposite to the first temporary chamber 112. The volume of the storage chamber 111 is less than or equal to the volume of the first temporary chamber 112.

[0056] When in operation, the filtering and conveying mechanism 200 is located at the bottom of the storage chamber 111; when in cleaning operation, the filtering and conveying mechanism 200 is located above the storage chamber 111.

[0057] like Figure 5 As shown, the filtration and conveying mechanism 200 is provided with a filter screen 210, a connecting wire 220, a first driven shaft 230 for resetting the filter screen 210, and a first driving shaft 240 for moving the filter screen 210. The two sides of the filter screen 210 are connected to the first driven shaft 230 and the first driving shaft 240 respectively through the connecting wire 220. The first driven shaft 230 and the first driving shaft 240 are respectively assembled with the first drive mechanism 300. The connecting wire 220 passes through the clearance slot 121.

[0058] During operation, the filter screen 210 is located at the bottom of the storage chamber 111; during cleaning, the filter screen 210 is located above the storage chamber 111, and is wound up outside the cylinder 110 via the first drive shaft 240. The bottom surface of the storage chamber 111 is a fixed plate.

[0059] It should be noted that the filter screen 210 of this utility model is connected to the first driven shaft 230 and the first driving shaft 240 via the connecting wire 220 to keep the filter screen 210 taut, and the filter screen 210 is raised and lowered under the action of the first driving mechanism 300. The absorbent body 700 of the self-cleaning pet toilet of this utility model can be replaced by opening a closable replacement port at the top of the main body 100, or by replacing it at the inlet / outlet 113, or by disassembling and replacing the filtering and conveying mechanism 200, the first driving mechanism 300, and the fixing plate 120. Furthermore, the inlet / outlet 113 can also be equipped with a sensor-activated closing door.

[0060] The first drive mechanism 300 is provided with a first motor (not shown in the figure) and two sets of first transmission mechanisms (not shown in the figure). One set of first transmission mechanisms is fixedly mounted on the outer surface of a fixed plate 120. The first motor is connected to the two sets of first transmission mechanisms respectively. One set of first transmission mechanisms is mounted to the first driven shaft 230, and the other set of first transmission mechanisms is mounted to the first drive shaft 240.

[0061] It should be noted that the first transmission mechanism can specifically be composed of a lead screw, a guide rod, and a nut block, wherein the nut block is fixedly assembled with the first driven shaft 230 or the first driving shaft 240. The first drive mechanism 300 of this invention uses a first motor to drive the movement of two sets of first transmission mechanisms. This ensures synchronous movement of the first driven shaft 230 and the first driving shaft 240, and also saves costs. The first motor can be installed inside the cylinder 110, located in the space between the storage compartment 111 and the cylinder 110. The transmission method between the first motor and the first transmission mechanism can be gear transmission or synchronous belt transmission, which can be selected according to the actual situation. Furthermore, the first driven shaft 230 of this invention also has a reset mechanism, such as a spring, which drives the filter screen 210 to reset when the driving force of the first driving shaft 240 is removed or reversed. The first driven shaft 230 and the first driving shaft 240 with these functions are widely used in industrial and daily consumer products, and those skilled in the art should be familiar with their structure and working principle; therefore, they will not be described in detail here.

[0062] The second drive mechanism 400 is provided with a second drive shaft 410 and a second driven shaft 420 for driving the cylinder 110 to reciprocate. The second drive shaft 410 and the second driven shaft 420 are both located outside the cylinder 110, and the second drive shaft 410 and the second driven shaft 420 are both meshed with the cylinder 110. The cross-sectional profile of the cylinder 110 is circular.

[0063] It should be noted that the second drive shaft 410 of this utility model drives the cylinder 110 to reciprocate through rotation, while the second driven shaft 420 also rotates under the reciprocating rotation of the cylinder 110.

[0064] The main body 100 is provided with a barrier grille 130 for preventing pets from contacting the inner wall surface. The barrier grille 130 is fixedly installed inside the cylinder 110 and is located at the edge of the storage compartment 111.

[0065] It should be noted that the barrier 130 is used to restrict the pet's movement, ensuring that the pet defecates within the storage compartment 111. Since the cylinder 110 needs to rotate to move the absorbent 700 to the first temporary compartment 112, the side wall of the cylinder 110 in the first temporary compartment 112 will become contaminated with the absorbent 700. The barrier 130 prevents the pet from contacting the side wall of the cylinder 110, thus avoiding the pet adhering to the contaminated absorbent 700 and preventing the spread of bacteria and viruses from the excrement 600. Because the cylinder 110 also has an entrance / exit 113, the barrier 130 also has a corresponding opening at the entrance / exit 113 to facilitate pet entry and exit.

[0066] like Figure 7As shown, the working process of this self-cleaning pet toilet is as follows: 1. After the pet enters the main body 100 through entrance / exit 113 to defecate; 2. The first driving mechanism 300 drives the filtration and conveying mechanism 200 to rise from the bottom of the storage chamber 111. The agglomerated adsorbent 700 and the excrement 600 are located above the filter screen 210, while the unagglomerated adsorbent 700 is located in the storage chamber 111. 3. After the filter screen 210 rises to the plane of the inlet / outlet channel 122, the first drive shaft 240 drives the filter screen 210 to rewind, and the clumps of adsorbent 700 and excrement 600 on the filter screen 210 are conveyed out of the self-cleaning pet toilet; the first driven shaft 230 drives the filter screen 210 to reset. 4. The rotation of the second drive mechanism 400 drives the main body 100, the filtering and conveying mechanism 200 and the first drive mechanism 300 to rotate as a whole, such as rotating 90°, 95°, 120°, etc., so that all the adsorbents 700 inside the storage chamber 111 are moved to the first temporary chamber 112. 5. The first drive mechanism 300 drives the filtering and conveying mechanism 200 to descend to the bottom of the storage chamber 111; 6. Finally, the second drive mechanism 400 rotates in the opposite direction, driving the main body 100, the filtering and conveying mechanism 200 and the first drive mechanism 300 to rotate as a whole, such as rotating -40°, so that all the adsorbents 700 in the first temporary chamber 112 are moved into the storage chamber 111, and then rotates back to 0°. At this time, the adsorbents 700 are located on the upper part of the filter screen 210, for the next filtration and conveying of the agglomerated adsorbents 700 and the excrement 600.

[0067] It should be noted that the self-cleaning pet toilet can also be equipped with a casing. The purpose of this casing is to ensure aesthetics and simplicity, guarantee the normal operation of the drive mechanism, and prevent accidental injury to the pet during operation. The casing can be placed outside the first drive mechanism 300, the second drive mechanism 400, etc., as long as it does not affect the operation of the self-cleaning pet toilet. The specific placement and location of the casing depend on the actual situation. The self-cleaning pet toilet is also equipped with a controller, such as a microcontroller, for controlling the operation of the filtration and conveying mechanism 200, the first drive mechanism 300, and the second drive mechanism 400. The connection method between the controller and the filtration and conveying mechanism 200, the first drive mechanism 300, and the second drive mechanism 400 is not the focus of this invention and will not be elaborated upon here. After a pet defecates, the self-cleaning pet toilet is triggered to begin cleaning. Specifically, the cleaning action is triggered by an infrared sensor detecting when the pet leaves.

[0068] This self-cleaning pet toilet can automatically separate excrement 600 and transport it to the outside. Furthermore, this invention uses a lifting and lowering filter and conveying mechanism 200 to separate the excrement 600 from the absorbent body 700, and then retracts it to transport the excrement 600 out of the self-cleaning pet toilet. This movement method does not generate significant vibration, thus preventing the excrement 600 from collapsing or breaking and extending the service life of the absorbent body 700.

[0069] Example 2 A self-cleaning pet toilet, such as Figure 8 and Figure 9 As shown, other features are the same as in Embodiment 1, except that: the second drive mechanism 400 is provided with a frame 430, a connecting arm 440 for connecting to the cylinder 110, a driven gear 450, a driving gear 460, and a second motor (not shown in the figure). The connecting arm 440 is fixedly connected to the cylinder 110 and is axially connected to the frame 430. The driven gear 450 is fixedly connected to the connecting arm 440 and meshes with the driving gear 460. The motor shaft of the second motor is drively connected to the driving gear 460.

[0070] The cross-sectional profile of the cylinder 110 is circular, regular polygonal, or irregular.

[0071] It should be noted that the second drive mechanism 400 of this utility model drives the main body 100, the filtering and conveying mechanism 200 and the first drive mechanism 300 to rotate as a whole through the connecting arm 440, the driven tooth 450, the driving tooth 460 and the second motor. At this time, the cross-section of the cylinder 110 is not limited to a circle. This embodiment uses a regular hexagon as an example for explanation.

[0072] Compared with Example 1, this example improves the flexibility of the shape of the cylinder 110.

[0073] Example 3 A self-cleaning pet toilet, such as Figure 10 and Figure 11 As shown, other features are the same as in Embodiment 1 or 2, except that: there is a second temporary compartment 115 for accommodating the adsorbent 700 between the lower part of the storage compartment 111 and the wall of the cylinder 110, and the storage compartment 111 is a movable structure 114 with a movable bottom opening and closing.

[0074] When the bottom of the movable structure 114 is opened, the storage compartment 111 and the second temporary compartment 115 are connected, or the second temporary compartment 115 is connected to the first temporary compartment 112; when the bottom of the movable structure 114 is closed, the storage compartment 111, the first temporary compartment 112 and the second temporary compartment 115 are not connected.

[0075] The movable structure 114 is equipped with multiple rotating blades 1141, connecting rods 1142, a third drive mechanism 1143, and a spring door 1144 for separating the storage compartment 111 and the first temporary compartment 112. The rotating blades 1141 are connected to the connecting rods 1142 respectively, and the connecting rods 1142 are drivenly connected to the third drive mechanism 1143. The spring door 1144 is rotatably mounted on the cylinder 110, and the edge of the spring door 1144 is in movable contact with the rotating blades 1141 located at the edge. The rotating blades 1141, connecting rods 1142 and spring door 1144 are all located inside the cylinder 110.

[0076] During the cleaning process, the rotating blade 1141 rotates, and the adsorbent 700 enters the second temporary chamber 115 under the action of gravity; when the main body 100 rotates, the spring door 1144 rotates under the action of gravity of the adsorbent 700 located in the second temporary chamber 115, and the adsorbent 700 enters the first temporary chamber 112 under the action of gravity.

[0077] like Figure 12 The working process of this self-cleaning pet toilet is as follows: 1. After the pet enters the main body 100 through the inlet 113 to defecate, the filter 210 is located at the bottom of the storage compartment 111; 2. The third drive mechanism 1143 drives the connecting rod 1142, and the rotating blade 1141 rotates, opening the storage chamber 111. The unclustered excrement 600 enters the second temporary chamber 115. Due to the obstruction of the filter screen 210, the clustered adsorbent 700 and the excrement 600 are located on the filter screen 210. Then, the third drive mechanism 1143 drives the connecting rod 1142 in the opposite direction, and the rotating blade 1141 rotates in the opposite direction, closing the storage chamber 111. 3. The first drive mechanism 300 drives the filtration and conveying mechanism 200 to rise from the bottom of the storage chamber 111, and the agglomerated adsorbent 700, excrement 600 and filter screen 210 rise as a whole; 4. After the filter screen 210 rises to the plane of the inlet / outlet channel 122, the first drive shaft 240 drives the filter screen 210 to rewind, and the clumps of adsorbent 700 and excrement 600 on the filter screen 210 are conveyed out of the self-cleaning pet toilet; the first driven shaft 230 drives the filter screen 210 to reset. 5. The rotation of the second drive mechanism 400 drives the main body 100, the filtering and conveying mechanism 200 and the first drive mechanism 300 to rotate as a whole, such as rotating 90°, 95°, or 120°. At this time, the spring door 1144 rotates under the gravity of the adsorbent 700, and the first temporary chamber 112 and the second temporary chamber 115 are connected, so that the adsorbent 700 enters the first temporary chamber 112; when the adsorbent 700 has completely or mostly entered the first temporary chamber 112, the spring door 1144 returns to its original position. 6. The first drive mechanism 300 drives the filtering and conveying mechanism 200 to descend to the bottom of the storage chamber 111; 7. The second drive mechanism 400 rotates in the opposite direction, causing the main body 100, the filtering and conveying mechanism 200 and the first drive mechanism 300 to rotate as a whole. For example, rotating -40° will cause all the adsorbents 700 in the first temporary chamber 112 to be transferred into the storage chamber 111. Then it rotates back to 0°. At this time, the adsorbents 700 are located on the upper part of the filter screen 210, which is used for the next filtration and conveying of the agglomerated adsorbents 700 and the excrement 600.

[0078] Compared with Example 1, in this example, the rotating blade 1141 causes the adsorbent 700 to fall into the second temporary chamber 115 in front of the filter agglomerate adsorbent 700 and the excrement 600, thereby avoiding the adsorbent 700 from exerting a gravitational load on the filter and conveying mechanism 200 during the upward process of the filter and conveying mechanism 200.

[0079] Example 4 An excrement collection system is provided, comprising a self-cleaning pet toilet as described in Embodiment 1 or Embodiment 2, and an odor-preventing collection mechanism 500, wherein the odor-preventing collection mechanism 500 is located at the excrement outlet 600 of the self-cleaning pet toilet. This embodiment is described using the self-cleaning pet toilet of Embodiment 1 as an example. Figure 13 .

[0080] The odor-preventing collection mechanism 500 is provided with a bag body 510, a bag opening for sealing the bag body 510, and a sealing mechanism for sealing the middle part of the bag body 510. The mechanism for sealing the bag opening of the bag body 510 is defined as the first sealing mechanism 520, and the mechanism for sealing the middle part of the bag body 510 is defined as the second sealing mechanism 530. The first sealing mechanism 520 is connected to the two opposite sides of the bag opening of the bag body 510, and the second sealing mechanism 530 is connected to the two opposite sides of the middle part of the bag body 510.

[0081] During the cleaning process, the first sealing mechanism 520 drives the bag opening of the bag body 510 to open, and the second sealing mechanism 530 drives the middle of the bag body 510 to seal, thereby allowing the excrement 600 from the self-cleaning pet toilet to enter the bag body 510; after the excrement 600 enters the bag body 510, the first sealing mechanism 520 drives the bag opening of the bag body 510 to seal, and the second sealing mechanism 530 drives the middle of the bag body 510 to open, thereby allowing the excrement 600 to enter the bottom of the bag body 510.

[0082] It should be noted that the sealing mechanism can be composed of a lead screw, a guide rod, and a nut block, wherein the nut block is fixedly connected to the side of the bag body 510 to achieve sealing drive.

[0083] The function of the double-sealing mechanism in this embodiment is to achieve 600% sealed storage of excrement, preventing odor leakage throughout the process. Figure 14 As shown, the specific process is as follows: Phase 1: Bag opening and center sealing. When the self-cleaning pet toilet's filtration mechanism delivers excrement 600 to the outlet, the first sealing mechanism 520 is activated, driving the two sides of the bag opening to open. At the same time, the second sealing mechanism 530 drives the two sides of the middle of the bag body 510 to close, forming a temporary space that is open at the top and sealed at the bottom. The excrement 600 falls directly into the upper half of the bag body 510. At this time, the center sealing can prevent the original odor inside the bag from escaping.

[0084] Second stage: Bag opening sealed, middle section opened. After the excrement 600 has completely fallen into the upper half of the bag body 510, the first sealing mechanism 520 drives the bag opening to close, sealing the odor of the newly fallen excrement 600. At the same time, the second sealing mechanism 530 drives the middle section of the bag body 510 to open, and the excrement 600 in the upper half falls into the bottom of the bag body 510 under the action of gravity.

[0085] Phase 3: Pending treatment. The central sealing mechanism re-closes the middle of bag 510, keeping the bag opening sealed, forming a double seal until the user replaces bag 510, ensuring that the indoor environment is not affected by the odor of excrement 600 throughout the process.

[0086] This waste collection system can automatically separate waste 600 and transport it to the outside. Furthermore, the system uses a filtration and conveying mechanism 200 to separate the waste 600 from the absorbent body 700, and then retracts it to transport the waste 600 out of the self-cleaning pet toilet. This movement method minimizes vibration, preventing the waste 600 from collapsing or breaking, and extending the lifespan of the absorbent body 700. Moreover, the system employs a double-sealing mechanism to ensure no odor leakage during waste collection.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
