Detailed implementation manners

[0020] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and effects according to the present invention as follows.

[0021] Please refer to Figures 1-12 , this embodiment provides a litter box with an automatic cleaning structure, including a litter box 1 with a hollow interior, a cleaning component 2, and a storage basin 3 with a hollow interior. The cleaning component 2 includes a cleaning shovel 201. The cleaning shovel 201 is slidably arranged in the litter box 1. The storage basin 3 is arranged at one end of the litter box 1. The interior of the storage basin 3 is interconnected with the interior of the litter box 1. The cleaning shovel 201 shovels the cat feces in the litter box 1 into the storage basin 3. By providing a slidable cleaning shovel 201, the cleaning shovel 201 sweeps the clumped cat litter and cat feces in the litter box 1 into the storage basin 3 together, realizing the automatic cleaning of the clumped cat litter and cat feces in the litter box 1. The owner only needs to clean out the clumped cat litter and cat feces in the storage basin 3, solving the problem that for the litter boxes on the market currently, the owner has to actively collect the cat feces in the litter box, which brings a lot of trouble to the owner. In terms of the cleaning process, the owner has to first use a shovel to shovel out the clumped cat litter and cat feces together. However, the space in the litter box is limited and it is not easy to operate, and there is a situation where the cat litter is scattered outside, increasing the extra cleaning work. The whole process is cumbersome and unhygienic. It is worth adding that the structure of the hollow litter box 1 in this solution facilitates the cleaning of the interior of the litter box 1 and the replacement of the cat litter.

[0022] Specifically, in order to realize the movement of the cleaning shovel 201, this solution further includes a base 4. The cleaning component 2 further includes a driving rack 202, a driving gear 203, a driving device 204, a driving wheel 205, and a cleaning unit. The litter box 1 is erected on the base 4. The driving rack 202 is arranged at the bottom of one end of the litter box 1. The driving device 204 is arranged at the bottom of the litter box 1. The output end of the driving device 204 is coaxially connected with the driving gear 203. The driving gear 203 is meshed with the driving rack 202. The driving wheel 205 is rotatably arranged on the driving device 204. The circumferential surface of the driving wheel 205 is tangent to the top surface of the base 4. The two ends of the cleaning unit are respectively connected with the output end of the driving device 204 and the cleaning shovel 201. By providing a driving device 204, the driving device 204 controls the driving gear 203 to rotate, so that the driving gear 203 meshes and moves along the setting direction of the driving rack 202, and then drives the cleaning unit to move along the setting direction of the driving rack 202, and finally realizes the movement of the cleaning shovel 201.

[0023] Specifically, the cleaning unit of this solution includes a vertical block 206 and a horizontal rod 207. A sliding groove is provided on the end face of the litter box 1, and the axis direction of the sliding groove is the same as that of the driving rack 202. The horizontal rod 207 is slidably arranged in the sliding groove. One end of the horizontal rod 207 located inside the litter box 1 is connected to the cleaning shovel 201, and the vertical block 206 is vertically arranged at one end outside the litter box 1. Both ends of the vertical block 206 are respectively connected to one end of the horizontal rod 207 extending outside the litter box 1 and the output end of the driving device 204. By providing the vertical block 206 and the horizontal rod 207, when the driving gear 203 starts to move, it will drive the vertical block 206 to move along with the movement of the driving gear 203, and then drive the horizontal rod 207 connected to the vertical block 206 to move, realizing the movement of the cleaning shovel 201.

[0024] When the cat enters the litter box 1 to excrete cat feces and urine, the cat will dig the litter. In order to prevent the cat from digging the litter into the storage basin 3, this solution further includes a lifting block 5. The lifting block 5 is arranged between the litter box 1 and the storage basin 3. The lifting block 5 is an arc-shaped block. In this solution, the lifting block 5 is an arc segment of a circle less than 1 / 4. One end of the lifting block 5 is tangentially connected to the inner bottom surface of the litter box 1, and the height of the other end of the lifting block 5 is the same as the height of the top of one end of the storage basin 3. By providing the lifting block 5, it can prevent the unclumped litter from being dug into the storage basin 3 when the cat digs the litter, improving the utilization rate of the litter.

[0025] According to the description of the above embodiments, since there is a lifting block 5 between the litter box 1 and the storage basin 3, the cleaning spatula 201 is also restricted from pushing the clumped cat litter and cat feces into the storage basin 3. Based on this, the cleaning component 2 of this solution further includes a rotating motor 208. There are two sets of sliding grooves, and the other sliding groove is symmetrically arranged at the other end of the litter box 1. Both ends of the cross bar 207 extend out of the litter box 1 through the sliding grooves at both ends. The rotating motor 208 is slidably arranged at one end outside the litter box 1, and the output end of the rotating motor 208 is coaxially connected to the cross bar 207; it should be noted that one end of the sliding groove of this solution close to the storage basin 3 and the position where the lifting block 5 is tangent to the bottom surface of the litter box 1 are in the same vertical plane. Therefore, when the cross bar 207 moves to one end of the sliding groove close to the storage basin 3, the cleaning spatula 201 is located at the tangent position between the lifting block 5 and the bottom surface of the litter box 1. At this time, the rotating motor 208 starts to rotate, controlling the cross bar 207 to start rotating, and then driving the cleaning spatula 201 to start rotating along the central axis of the cross bar 207; it is worth noting that when the cross bar 207 moves to one end of the sliding groove close to the storage basin 3, the center position of the lifting block 5 is located on the central axis of the cross bar 207. Therefore, when the cleaning spatula 201 starts to rotate, it will move the clumped cat litter and cat feces along the arc surface of the lifting block 5 until the clumped cat litter and cat feces move to the other end of the lifting block 5. At this time, the cleaning spatula 201 is at an inclined angle, so the clumped cat litter and cat feces on the cleaning spatula 201 fall into the storage basin 3 due to gravity, realizing the cleaning of the clumped cat litter and cat feces.

[0026] Specifically, the cleaning component 2 of this solution further includes a reset module 209, a limit module 210 and a pressing block 211. The vertical block 206 is provided with an installation slot hole. The pressing block 211 is coaxially connected to the other end of the cross bar 207. The pressing block 211 is located in the installation slot hole. The reset module 209 and the limit module 210 are both arranged in the installation slot hole. The limit module 210 and the reset module 209 are respectively located at both ends of the pressing block 211. When the pressing block 211 presses the reset module 209, the cleaning spatula 201 is vertically arranged; the cleaning spatula 201 rotates until the pressing block 211 presses the limit module 210, and the height of the end of the cleaning spatula 201 is equal to the height of the end of the lifting block 5 close to the storage basin 3. By providing the reset module 209 and the limit module 210, the rotation angle of the cleaning spatula 201 can be jointly restricted to ensure that the cleaning spatula 201 can work smoothly.

[0027] It should be noted that the cleaning method of the agglomerated cat litter and cat feces by the storage basin 3 in this solution is that there is a storage space between the storage basin 3 and the lifting block 5. The plastic bag is arranged in the storage space, and both ends of the plastic bag are respectively connected to one end of the storage basin 3 and one end of the lifting block 5. And at least two places at one end of the bag mouth of the plastic bag are simultaneously connected to two places at one end of the storage basin 3, or two places at one end of the lifting block 5. With such a setting, by opening the bag mouth of the plastic bag, the agglomerated cat litter and cat feces can be transported into the plastic bag through the lifting block 5, and the owner only needs to take away the plastic bag to complete the cleaning of the storage basin 3. In order to ensure that the bag mouth in the storage space is in an open state before the cleaning shovel 201 pushes the agglomerated cat litter and cat feces into the storage basin 3 through the lifting block 5, this solution also includes a linkage rod 6. Both ends of the linkage rod 6 are respectively connected to the vertical block 206 and the storage basin 3. The sliding direction of the linkage rod 6 is parallel to the axis direction of the driving rack 202. While the linkage rod 6 controls the sliding of the storage basin 3, it also controls the opening and closing of the bag mouth of the plastic bag. With such a setting, when the vertical block 206 moves, it will drive the storage basin 3 to start moving through the linkage rod 6, thereby realizing that the bag mouth of the plastic bag is in an open state, so that before the shovel pushes the agglomerated cat litter and cat feces into the storage basin 3 through the lifting block 5, the bag mouth in the storage space is in an open state; similarly, when the vertical block 206 resets, it will drive the storage basin 3 to reset through the linkage rod 6, thereby realizing that the plastic bag is in a closed state, which is convenient for sealing the plastic bag and isolating the smell inside the plastic bag.

[0028] Furthermore, in order to ensure that the agglomerated cat litter in this solution does not stick to the bottom surface of the cat litter basin 1, this solution also includes a number of flexible blocks 7. The number of flexible blocks 7 is arranged on the bottom surface in the cat litter basin 1. The distance between two adjacent flexible blocks 7 is less than the thickness of the cat feces, and the top surface height of the flexible block 7 is slightly higher than the bottom surface height of the cleaning shovel 201. With such a setting, the contact area between the agglomerated cat litter and the flexible block 7 becomes smaller, which is equivalent to reducing the adhesion force of the agglomerated cat litter to the flexible block 7, making it more convenient for the cleaning shovel 201 to clean the agglomerated cat litter. In addition, since the bottom surface height of the cleaning shovel 201 is slightly lower than the top surface height of the flexible block 7, it can ensure that the agglomerated cat litter on the flexible block 7 can be cleaned up.

[0029] It should be noted that the cleaning shovel 201 in this solution is composed of a number of cleaning rollers. The number of cleaning rollers is arranged at equal intervals along the axis direction of the transverse rod 207. The distance between two adjacent cleaning rollers is less than the width of the agglomerated cat litter and greater than the width of the unagglomerated cat litter.

[0030] In addition, when the cleaning spatula 201 is in an unused state, a rolling curtain is needed to cover the cleaning spatula 201 to prevent the cat from playing with the cleaning spatula 201 in the litter box 1, which may cause the cleaning spatula 201 to malfunction; secondly, it is to prevent the cat from excreting cat feces on the cleaning spatula 201; based on this, this solution also includes an elastic rolling curtain 8 and a sliding block 9. In fact, several sliding blocks 9 are provided in this solution, and several sliding blocks 9 correspond to and match several cleaning rollers one by one. Any sliding block 9 is slidably arranged on the corresponding cleaning roller, so that the sliding block 9 is slidably arranged on the cleaning spatula 201. The two ends of the elastic rolling curtain 8 are respectively connected to the side wall in the litter box 1 and several sliding blocks 9; and the natural length of the elastic rolling curtain 8 is less than the set length of the sliding groove, and the natural length of the elastic rolling curtain 8 is equal to the height of the cleaning spatula 201; such a setting enables the elastic rolling curtain 8 to drive the sliding block 9 to move towards the top of the cleaning spatula 201 during the movement of the cleaning spatula 201, exposing the bottom of the cleaning spatula 201 to clean the clumped cat litter and cat feces in the litter box 1; and when the cleaning spatula 201 is reset, the elastic rolling curtain 8 will drive the sliding block 9 to move towards the bottom of the cleaning spatula 201 until the elastic rolling curtain 8 covers the cleaning spatula 201.

[0031] It is also worth noting that, in order to limit the sliding position of the sliding block 9, this solution further includes a height limiting block 10 and a low limiting block 11. The height limiting block 10 and the low limiting block 11 are respectively arranged at the top and bottom of the cleaning shovel 201, and the height limiting block 10 and the low limiting block 11 are respectively used to limit the sliding position of the sliding block 9; when the sliding block 9 abuts and fits against the height limiting block 10, both ends of the elastic rolling curtain 8 are on the same horizontal plane, and when the cleaning shovel 201 is located at the end where the lifting block 5 is tangent to the bottom surface in the cat litter box 1, the elastic rolling curtain 8 is in a horizontal unfolded state; it should be noted that when the cleaning shovel 201 starts to move, due to the length limitation of the elastic rolling curtain 8, the sliding block 9 will gradually move towards the top of the cleaning shovel 201 until the sliding block 9 abuts and fits against the height limiting block 10. At this time, the height at which the elastic rolling curtain 8 is connected to the sliding block 9 is the same as the height at which the other end of the elastic rolling curtain 8 is connected to the cat litter box 1; at this time, when the cleaning shovel 201 continues to move, the elastic rolling curtain 8 will deform and cooperate with the continuous movement of the cleaning shovel 201 until the cleaning shovel 201 moves to the position of the lifting block 5; it should be noted that the purpose of setting the elastic rolling curtain 8 in this solution is to prevent the cleaning shovel 201 from being unable to be normally reset due to the limitation of foreign objects during the reset period when foreign objects fall into the cat litter box 1 during the movement of the cleaning shovel 201, which may lead to the abnormal use of the cat litter box 1. In addition, it is also worth noting that the central axis height of the horizontal rod 207 in this solution is higher than the connection height between the elastic rolling curtain 8 and the sliding block 9 when the height limiting block 10 and the sliding block 9 are in mutual contact. Therefore, when the cleaning shovel 201 moves to the position of the lifting block 5, the horizontal rod 207 controls the rotation of the cleaning shovel 201 by rotating, thereby changing the connection height between the elastic rolling curtain 8 and the sliding block 9 when the height limiting block 10 and the sliding block 9 are in mutual contact. At this time, the connection height between the elastic rolling curtain 8 and the sliding block 9 is higher than the connection height between the other end of the elastic rolling curtain 8 and the cat litter box 1. At this time, the elastic rolling curtain 8 starts to be inclined, and the foreign objects on the elastic rolling curtain 8 will move towards the lower inclined end of the elastic rolling curtain 8 due to the inclined setting of the elastic rolling curtain 8.At this time, two situations will occur. In the first situation, that is, the height of the foreign object is less than the distance between the elastic rolling curtain 8 and the top of the litter box 1. The foreign object slides along the inclined direction of the elastic rolling curtain 8 to the connection between the elastic rolling curtain 8 and the litter box 1. Since there is a gap at the connection between the elastic rolling curtain 8 and the litter box 1, the foreign object will fall into the litter box 1 along this gap. It should be noted that the space of the litter box 1 under this gap is a vacant space, and there is no cat litter in the vacant space. Therefore, the foreign object falling at this position will not affect the reset of the cleaning shovel 201. And by opening a through hole on the side wall of the litter box 1, the through hole is communicated with the vacant space, and the foreign object can be taken out through the through hole. In the second situation, that is, the height of the foreign object is greater than the distance between the elastic rolling curtain 8 and the top of the litter box 1. When the cleaning shovel 201 is reset, the foreign object will cross the horizontal rod 207 and fall into the litter box 1. Since the cleaning shovel 201 is behind the foreign object at this time, it will not affect the reset of the cleaning shovel 201.

[0032] It should be noted that in order to enable the foreign object on the elastic rolling curtain 8 to smoothly cross the horizontal rod 207 and fall into the litter box 1 during the reset process of the cleaning shovel 201, an auxiliary block 15 is provided in this solution. The cross-sectional shape of the auxiliary block 15 is arc-shaped. The auxiliary block 15 is arranged at the end of the horizontal rod 207 far from the storage basin 3. One end of the auxiliary block 15 is tangent to the top of the horizontal rod 207, and the set height of the other end is the same as the height of the elastic rolling curtain 8 when the sliding block 9 and the height limiting block 10 are in contact and fit. It is also worth noting that the distance between the end surface of the top of the litter box 1 close to the storage basin 3 and the cleaning shovel 201 when it is reset is greater than the height of the cleaning shovel 201. Such a setting can ensure that before the cleaning shovel 201 is hidden under the top of the litter box 1, the extended elastic rolling curtain 8 is in a stretched state. Thus, when the cleaning shovel 201 is reset, the foreign object can fall into the litter box 1 along the auxiliary block 15.

[0033] Furthermore, the set height of the low limiting block 11 is higher than the set height of the flexible block 7. Such a setting is to prevent the elastic rolling curtain 8 from touching the clumped cat litter and cat feces.

[0034] According to the description of the above embodiments, the plastic bag is disposed in the storage space for collecting the clumped cat litter and cat feces pushed into the storage space by the cleaning shovel 201; specifically, the plastic bag is provided with four bag buckles, which are divided into two groups and are respectively disposed at both ends of the bag mouth, and the two bag buckles of each group are respectively disposed on the left and right sides of one end of the bag mouth; correspondingly, two hook assemblies 12 are disposed at one end of the lifting block 5 close to the storage basin 3, and the two hook assemblies 12 are respectively disposed on both sides of the lifting block 5. The hook assembly 12 includes a hook block 1205, and the hook block 1205 is provided with a hook groove 12051. The two hook blocks 1205 respectively correspond to the two bag buckles at one end of the plastic bag, and the bag buckles are hung on the corresponding hook grooves 12051 to realize the connection between one end of the plastic bag and the hook block 1205; similarly, two fixed hooks 13 are disposed at one end of the storage basin 3 close to the lifting block 5, and the two fixed hooks 13 are respectively disposed on both sides of the storage basin 3. The fixed hook 13 is provided with a fixed hanging groove 1301, and the two fixed hooks 13 respectively correspond to the two bag buckles at the other end of the plastic bag, and the bag buckles are hung on the corresponding fixed hanging grooves 1301 to realize the connection between the other end of the plastic bag and the fixed hook 13; the height of the plastic bag is always less than the distance between the hook block 1205 and the bottom surface of the storage basin 3. It should also be noted that in order to further ensure that the plastic bag can be stably hung on the hook groove 12051 and the fixed hanging groove 1301, the width of the transverse notch of the hook groove 12051 gradually decreases from the direction of the lifting block 5 to the storage basin 3; the width of the transverse notch of the fixed hanging groove 1301 gradually increases from the direction of the lifting block 5 to the storage basin 3.

[0035] Based on this, when the cleaning shovel 201 starts to move, it will drive the linkage rod 6 to start moving, thereby realizing the movement of the storage basin 3 in the direction away from the lifting block 5. During the movement of the storage basin 3, the bag buckles of the plastic bag will move in the direction where the width of the transverse notch of the corresponding hook groove 12051 or the fixed hanging groove 1301 becomes smaller, so that the plastic bag can be stably hung in the storage space, and the bag mouth of the plastic bag gradually becomes larger until the cleaning shovel 201 pushes the clumped cat litter and cat feces into the plastic bag; since then, the cleaning shovel 201 starts to perform a reset movement. During the reset movement of the cleaning shovel 201, it drives the storage basin 3 to move in the direction close to the lifting block 5, so that the bag mouth of the plastic bag gradually becomes smaller. However, since the bag buckles of the plastic bag are already engaged in the hook groove 12051 or the fixed hanging groove 1301 and cannot move at this time, the plastic bag can always be stably hung in the storage space.

[0036] In addition, it should be noted that after the cleaning shovel 201 is reset, the lifting block 5 and the storage basin 3 do not fit together at this time. Instead, there is a certain distance between them, and at this time, the cleaning shovel 201 has not moved to the end of the sliding groove far from the storage basin 3. Since there is still a certain distance between the lifting block 5 and the storage basin 3, it means that the bag opening of the plastic bag is also in an open state, and the clumped cat litter and cat feces in the plastic bag emit a stench. In order to achieve the deodorization effect of the plastic bag, in this solution, the two bag buckles on both sides of the plastic bag need to be respectively placed on the two hook blocks 1205 to achieve the minimized state of the bag opening, thereby achieving the deodorization state. Based on this, the cleaning shovel 201 will continue to move towards the end of the sliding groove far from the storage basin 3. When the cleaning shovel 201 moves to the end of the sliding groove far from the storage basin 3, the lifting block 5 and the storage basin 3 fit together. Then, after the cleaning shovel 201 is reset again, the bag buckle on the fixed hanging groove 1301 moves to the same-side hook groove 12051, so that two bag buckles on the same side are hung on one hook groove 12051, thereby achieving the minimized state of the bag opening and ensuring that the stench of the clumped cat litter and cat feces in the plastic bag cannot escape.

[0037] It should be noted that, in order to achieve the above structural effect, taking the hook assembly 12 on one side as an example, the hook assembly 12 in this solution further includes a vertical sliding block 1201, a vertical sliding spring 1202, a horizontal sliding block 1203, and a horizontal sliding spring 1204. The lifting block 5 is provided with two mating slot holes, and the two mating slot holes are in one-to-one correspondence and match with the two hook assemblies 12. Any hook assembly 12 is arranged in the corresponding mating slot hole. The vertical sliding block 1201 is vertically arranged in the mating slot hole. The horizontal sliding block 1203 is horizontally arranged on the vertical sliding block 1201. The horizontal sliding block 1203 can slide along the axial direction of the vertical sliding block 1201 on the vertical sliding block 1201. The vertical sliding spring 1202 is arranged in the mating slot hole. The two ends of the vertical sliding spring 1202 are respectively connected to the horizontal sliding block 1203 and the lifting block 5. The hook block 1205 can slide along the axial direction of the horizontal sliding block 1203 on the horizontal sliding block 1203. The two ends of the horizontal sliding spring 1204 are respectively connected to the hook block 1205 and the horizontal sliding block 1203. Through such a setting, it is realized that the hook block 1205 can slide along the axial direction of the vertical sliding block 1201 and the axial direction of the horizontal sliding block 1203; in addition, two sliding slot holes 14 are opened at one end of the storage basin 3 close to the lifting block 5. The two sliding slot holes 14 are in one-to-one correspondence and match with the two fixed hooks 13. Any sliding slot hole 14 is arranged near the corresponding fixed hook 13. The sliding slot hole 14 is in a "C" shape with one end open when viewed from the end face of the storage basin 3. The fixed hook 13 is arranged in the middle of the sliding slot hole 14. And from bottom to top, the depth of the sliding slot hole 14 is deeper, and the depth of the bottom slot hole of the sliding slot hole 14 gradually increases obliquely towards the left end. The depth of the middle slot hole of the sliding slot hole 14 gradually increases obliquely towards the upper end. The depth of the top slot hole of the sliding slot hole 14 gradually increases obliquely towards the right end. The slot holes at each end of the sliding slot hole 14 are interconnected. And the four corners at the front end of the hook block 1205 are all inclined. The projection of the initial position of the hook block 1205 on the end face of the storage basin 3 is located at the right end of the bottom slot hole of the sliding slot hole 14. Through such a setting, as the distance between the lifting block 5 and the storage basin 3 decreases, the hook block 1205 cooperates with the sliding slot hole 14. While the hook block 1205 continuously extends from the bottom slot hole of the sliding slot hole 14, it also moves towards the left end; then while the hook block 1205 continuously extends from the middle slot hole of the sliding slot hole 14, it also moves towards the upper end; finally, while the hook block 1205 continuously extends from the top slot hole of the sliding slot hole 14, it also moves towards the right end; when the lifting block 5 is in contact with the storage basin 3, at this time the hook block 1205 is directly above the corresponding fixed hook 13. It should also be noted that, in order to ensure that the fixed hook 13 can extend into the lifting block 5, the projection area of the mating slot hole of the lifting block 5 on the end face of the storage basin 3 will cover the projection area of the sliding slot hole 14 and the fixed hook 13 on the end face of the storage basin 3 together;And at this time, the bag buckle at the end of the fixed hook 13 is located on the hook block 1205. It should be noted that the depth of the sliding slot hole 14 is the same as the distance from the hook slot 12051 of the hook block 1205 to the end face of the hook block 1205 close to one end of the storage basin 3. Therefore, when the hook block 1205 finishes extending into the sliding slot hole 14, the bag buckle at the end of the fixed hook 13 is located on the hook slot 12051 of the hook block 1205; as the lifting block 5 and the storage basin 3 are separated from each other and reset, the two bag buckles on the same side of the plastic bag are both located on the corresponding hook blocks 1205. The hook blocks 1205 are reset due to the action of the vertical sliding spring 1202 and the horizontal sliding spring 1204, realizing the closing of the plastic bag mouth, so as to achieve the purpose of deodorization.;
