Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for pet breeding, in particular to a cleaning shovel and a cat litter box. Background Art

[0002] Cat litter box problems have always been a challenge for pet owners. The advent of cat litter boxes has provided an effective solution. Cat litter boxes leverage the natural instincts of pet cats, allowing them to cover and bury their waste with litter after excretion, thus maintaining a clean environment. However, if the litter is not promptly disposed of, the litter box will become messy. Cats, driven by a love of cleanliness, may develop a reluctance to use the litter box, rendering the litter box's guiding function ineffective.

[0003] To solve this problem, the prior art has realized the automatic excrement shoveling function of cat litter boxes. Such automatic excrement shoveling cat litter boxes can clean the cat litter in time and keep the cat litter box clean, thereby reducing the cat's resistance to the cat litter box and improving the guiding effect of the cat litter box.

[0004] However, the detachable shovel body of the automatic shit shoveling mechanism in the prior art is clamped by rotating and clamping the connecting end of the shovel body. Since the contact area between the rotating parts is small, the rotating connection is prone to loosening after being used for a long time and subjected to force, making the shovel body unstable. Moreover, as the shovel body is continuously disassembled and cleaned, the loosening of the rotating parts will be aggravated, and the clamping force on the shovel body will gradually decrease, causing the shovel body to shake during use, thereby affecting the cleaning effect.

A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0045] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0046] like Figures 1-10 As shown, the utility model provides a cleaning shovel, which includes a connecting frame 1, a shovel body 2, a fixing base 3 and a movable block 4. The connecting frame 1 is configured to be connected to a driving mechanism 200 of a cat litter box. The connecting frame 1 includes a flat first connecting end 11; the shovel body 2 includes a flat second connecting end 21; the fixing base 3 is provided with a fixing groove 31 that passes through along a first direction. When the first connecting end 11 and the second connecting end 21 are both clamped in the fixing groove 31, the fixing groove 31 limits the first connecting end 11 and the second connecting end 21 to rotate around their own axis. Both ends of the fixing base 3 in the second direction are respectively provided with convex ridges 32, and the second direction is perpendicular to the first direction. The movable block 4 is provided with a hook structure 41 on the opposite sides. When the two hook structures 41 hook the two ridges 32 in a one-to-one manner, the movable block 4 can slide relative to the fixed seat 3. On the fixed seat 3 and the movable block 4, one is provided with a first positioning protrusion 33, and the other is provided with a first positioning groove. When the movable block 4 slides to the notch of the cover fixing groove 31, the first positioning protrusion 33 is clamped in the first positioning groove, and the first connecting terminal 11 and the second connecting terminal 21 are locked between the movable block 4 and the fixed seat 3. When the movable block 4 slides to the notch of the open fixing groove 31, the first connecting terminal 11 and the second connecting terminal 21 can be moved out of the fixing groove 31.

[0047] In the present invention, a flat first connecting end 11 is provided on the connecting frame 1, a flat second connecting end 21 is provided on the shovel body 2, and a fixing groove 31 is provided on the fixing seat 3 that runs through the first direction, so that the first connecting end 11 and the second connecting end 21 can be clamped in the fixing groove 31. Since the ends are flat, the fixing groove 31 limits the first connecting end 11 and the second connecting end 21 to rotate around their own axes; at the same time, convex ridges 32 are respectively provided at both ends of the second direction of the fixing seat 3, and the second direction is perpendicular to the first direction. Hook structures 41 are provided on opposite sides of the movable block 4. When the two hook structures 41 correspond to the hook ridges 32 one by one, the movable block 4 can slide relative to the fixing seat 3, and the fixing seat 3 and On the two movable blocks 4, one is provided with a first positioning protrusion 33, and the other is provided with a first positioning groove. When the movable block 4 slides to the notch of the cover fixing groove 31, the first positioning protrusion 33 is clamped in the first positioning groove, so that the first connecting end and the second connecting end are locked between the movable block 4 and the fixed seat 3, and the hook structure 41 hooks on the convex ridge 32 to form a mechanical locking structure. This structure is direct and firm, so that the shovel body 2 can remain stable regardless of whether it is used in a static or dynamic environment. Moreover, the connection method of the hook structure 41 and the convex ridge 32 is durable, with a low risk of damage, and the clamping force on the shovel body 2 is not easy to weaken. Even if it is disassembled many times and used for a long time, the installation stability of the shovel body 2 can be maintained.

[0048] In this embodiment, when the two hook structures 41 disengage from the two ridges 32, the movable block 4 is removed from the fixed seat 3. At this time, the movable block 4 is slidably connected to the fixed seat 3 along the first direction, and the first connecting end 11 and the second connecting end 21 extend into the fixed seat 3 from both ends of the first direction on the fixed seat 3, and the length of the two hook structures 41 in the first direction is the same as the length of the movable block 4 in the first direction, and the length of the two ridges 32 in the first direction is the same as the length of the fixed seat 3 in the first direction, so that the direct hooking of the hook structure 41 and the ridge 32 is more firm and reliable, so that the installation stability of the shovel body 2 is stronger.

[0049] In other embodiments, the movable block 4 may be slidably connected to the fixed base 3 and cannot be removed from the fixed base 3. At this time, the movable block 4 is slidably connected to the fixed base 3 along the first direction, and the first connecting end 11 and the second connecting end 21 extend into the fixed base 3 from both ends of the second direction on the fixed base 3. The first direction is perpendicular to the second direction, and the length of the two hook structures 41 in the first direction is not necessarily the same as the length of the movable block 4 in the first direction, and the length of the two ridges 32 in the first direction is not necessarily the same as the length of the fixed base 3 in the first direction.

[0050] In this embodiment, a first positioning protrusion 33 is provided on the fixing seat 3 , and a first positioning groove is provided on the movable block 4 .

[0051] In other embodiments, the movable block 4 may be provided with a first positioning protrusion 33 , and the fixed seat 3 may be provided with a first positioning groove.

[0052] Specifically, one of the first connecting terminal 11 and the inner wall of the fixing groove 31 is provided with a second positioning groove 111, and the other is provided with a second positioning protrusion, which is snap-fitted into the second positioning groove 111; and / or one of the second connecting terminal 21 and the inner wall of the fixing groove 31 is provided with a third positioning groove 211, and the other is provided with a third positioning protrusion, which is snap-fitted into the third positioning groove 211. The above configuration can improve the positioning and assembly accuracy of the first connecting terminal 11 on the fixing base 3, and / or the positioning and assembly accuracy of the second connecting terminal 21 on the fixing base 3.

[0053] More specifically, one of the first connecting end 11 and the fixing slot 31 is provided with a second positioning slot 111, and the other is provided with a second positioning protrusion. In addition, one of the second connecting end 21 and the fixing slot 31 is provided with a third positioning slot 211, and the other is provided with a third positioning protrusion. During the installation process, when the first connecting end 11 and the second connecting end 21 are inserted into the fixing slot 31, the corresponding second positioning protrusion and the third positioning protrusion will accurately snap into the corresponding positioning slots, ensuring that the relative position between the shovel body 2 and the connecting frame 1 is accurate, while preventing the first connecting end 11 and the second connecting end 21 from rotating in the fixing slot 31, thereby improving the stability of the connection. Moreover, on the basis of the first connecting end 11 and the second connecting end 21 being snapped into the fixing slot 31, the second positioning protrusion and the third positioning protrusion are snapped into the second positioning slot 111 and the third positioning slot 211 respectively, thereby forming a multiple snap-fit ​​structure, making the connection between the shovel body 2, the connecting frame 1 and the fixing seat 3 more stable.

[0054] In other embodiments, the second positioning groove 111 and the second positioning protrusion may not be provided, and only the second connecting end 21 and the fixing groove 31 may be provided with a third positioning groove 211 on one and a third positioning protrusion on the other; or the third positioning groove 211 and the third positioning protrusion may not be provided, and only the first connecting end 11 and the fixing groove 31 may be provided with a second positioning groove 111 on one and a second positioning protrusion on the other.

[0055] like Figure 2 and Figure 6 As shown, in this embodiment, the first connecting terminal 11 is provided with a second positioning groove 111 , the second connecting terminal 21 is provided with a third positioning groove 211 , and correspondingly, the fixing groove 31 is provided with a second positioning protrusion and a third positioning protrusion.

[0056] In other embodiments, a second positioning protrusion may be provided on the first connecting end 11, a third positioning groove 211 may be provided on the second connecting end 21, and a second positioning groove 111 and a third positioning protrusion may be provided on the fixing groove 31; a second positioning protrusion may be provided on the first connecting end 11, a third positioning protrusion may be provided on the second connecting end 21, and a second positioning groove 111 and a third positioning groove 211 may be provided on the fixing groove 31; a second positioning groove 111 may be provided on the first connecting end 11, a third positioning protrusion may be provided on the second connecting end 21, and a second positioning protrusion and a third positioning groove 211 may be provided on the fixing groove 31.

[0057] Specifically, if Figure 7 As shown, the connecting frame 1 further includes a connecting rod 12, which is connected to the first connecting end 11, and the shovel body 2 further includes a shovel arm 22, which is connected to the second connecting end 21. The fixing base 3 is provided with a support portion 34, and the connecting rod 12 and the shovel arm 22 are both in contact with the support surface of the support portion 34. The provision of the support portion 34 can effectively prevent the connecting rod 12 and the shovel arm 22 from shaking or deflecting, further ensuring the stability of the connection between the connecting frame 1 and the shovel body 2 and the fixing base 3.

[0058] More specifically, the fixing groove 31 is recessed relative to the support surface. First, the recessed fixing groove 31 provides a clearer positioning reference for the first and second connecting terminals 11, 21, improving installation efficiency and precision. Second, due to the recessed fixing groove 31, the movement of the first and second connecting terminals 11, 21 in all directions is constrained by the walls of the fixing groove 31, thereby improving the installation stability of the first and second connecting terminals 11, 21.

[0059] More specifically, if Figure 8 As shown, when the movable block 4 slides to the notch of the cover fixing groove 31, two communicating channels are formed between the support portion 34 and the movable block 4. The connecting rod 12 is passed through one communicating channel, and the shovel arm 22 is passed through the other communicating channel. The two communicating channels can effectively prevent the connecting rod 12 and the shovel arm 22 from shaking or displacing during operation, and can prevent the connecting rod 12 and the shovel arm 22 from interfering with each other.

[0060] More specifically, the two connecting channels are located on opposite sides of the fixing groove 31 and are respectively connected to the fixing groove 31. The relative position setting can make the structure of the cleaning shovel more symmetrical, which is beneficial to the uniform distribution of pressure between the connecting rod 12 and the shovel arm 22 on the fixed block 3, thereby improving the stability of the overall structure. At the same time, the limiting channel is connected to the fixing groove 31. Under the dual restrictions of the limiting channel and the fixing groove 31, the connection between the connecting frame 1 and the shovel body 2 and the fixed seat 3 is more stable.

[0061] Specifically, the shovel body 2 also includes a shovel brush 23, and the two ends of the shovel brush 23 in the length direction are respectively connected to a second connecting end 21 through a shovel arm 22. The shovel arm 22 is perpendicular to the length direction of the shovel brush 23. When the shovel body 2 needs to be installed, the operator can adjust the shovel arm 22 to a suitable angle so that the second connecting end 21 can be smoothly inserted into the fixing groove 31; and when the shovel body 2 needs to be disassembled for cleaning or maintenance, the vertically arranged shovel arm 22 also makes the pulling out action easier, reducing the operation time.

[0062] like Figure 8 and Figure 10 As shown, in this embodiment, the cleaning shovel includes two connecting rods 12 and two fixing seats 3, the shovel body 2 includes two shovel arms 22 and a shovel brush 23, one end of the shovel brush 23 is connected to one of the shovel arms 22, and the other end of the shovel brush 23 is connected to the other shovel arm 22. The two shovel arms 22 are inserted into their respective corresponding limiting channels in opposite directions, and a connecting rod 12 is inserted into the limiting channel on the opposite side of each shovel arm 22. The two connecting channels are arranged relative to each other, which not only facilitates the connection between the connecting rod 12 and the output end of the cat litter box drive mechanism 200, but also facilitates the connection between the shovel arm 22 and the shovel brush 23, so that the cleaning shovel can be arranged across the top of the basin body 100.

[0063] Specifically, if Figure 5 and Figure 7 As shown, the fixing seat 3 is provided with two fixing grooves 31, the first connecting terminal 11 is clamped in one fixing groove 31, and the second connecting terminal 21 is clamped in the other fixing groove 31. During the installation process, this one-to-one correspondence helps to achieve precise installation positioning, and the operator can more intuitively insert each terminal into the corresponding fixing groove 31, thereby improving the accuracy and efficiency of the installation. The two fixing grooves 31 correspond to the first connecting terminal 11 and the second connecting terminal 21 respectively, so that the first connecting terminal 11 and the second connecting terminal 21 are independent of each other and do not interfere with each other. If it is found during the installation process that a certain terminal is not tightly fitted with the fixing groove 31 or the position is inaccurate, the fixing groove 31 where the terminal is located can be fine-tuned separately without affecting the installation status of the other terminal, thereby facilitating the debugging work during the installation process.

[0064] Specifically, if Figures 1-4 As shown, the first connecting end 11 is provided with a first connecting hole 112, and the fixing base 3 is provided with a second connecting hole 35. The second connecting hole 35 is connected to the first connecting hole 112 and is penetrated by a connecting piece 5, so that the connection between the first connecting end 11 and the fixing base 3 is more stable and convenient to install. It is only necessary to align the first connecting hole 112 with the second connecting hole 35 on the fixing base 3, and then insert the connecting piece 5.

[0065] In this embodiment, the first connecting end 11 is provided with two first connecting holes 112, and the first connecting end 11 is clamped in a fixing groove 31. Two pairs of second connecting holes 35 are arranged opposite to each other on both sides of the fixing groove 31. Each pair of second connecting holes 35 is connected to one first connecting hole 112 and is penetrated by a connecting member 5, so that the connection between the first connecting end 11 and the fixing base 3 is more stable.

[0066] In other embodiments, according to the size of the first connecting end 11 and the fixing base 3 , the first connecting holes 112 can also be set to 3, 4 or more, and the second connecting holes 35 can be set correspondingly according to the number of the first connecting holes 112 .

[0067] In this embodiment, the connecting member 5 is a bolt, which is screwed into the second connecting hole 35. During the installation process, the bolt is tightened, and the friction between the threads will prevent the bolt from loosening automatically, so that the bolt can provide a lasting fastening force in the connecting structure, ensuring a tight connection between the first connecting end 11 and the fixing base 3.

[0068] In other embodiments, the connecting member 5 may also be a pin, a screw, etc.

[0069] In this embodiment, Figure 6 As shown, the shovel body 2 includes a shovel brush 23, which includes a plurality of shovel teeth 231 arranged in parallel. The shovel teeth 231 are provided with sand leakage grooves 2311. During the cleaning process, when the shovel teeth 231 are inserted into the cat litter, part of the cat litter will inevitably be scooped up. The sand leakage grooves 2311 can allow the scooped cat litter to flow back to the cat litter box in time, especially when encountering relatively wet or sticky cat litter, the grooves can prevent the cat litter from accumulating on the shovel teeth 231, thereby ensuring the cleaning effect of the shovel body 2.

[0070] In this embodiment, a shovel tooth sleeve is also provided at the bottom of the shovel tooth 231. The shovel tooth sleeve is made of a wear-resistant and relatively soft material. During the movement of the shovel tooth 231, the shovel tooth sleeve is in direct contact with the bottom of the basin body 100, rather than the shovel tooth 231 itself being in contact with the bottom of the basin body 100. This greatly reduces the direct friction of the shovel tooth 231 on the bottom of the basin body 100, thereby reducing the risk of wear on the bottom of the basin body 100.

[0071] like Figure 10 As shown, the utility model also provides a cat litter box, including a basin body 100, a driving mechanism 200 and a cleaning shovel. The connecting frame 1 is connected to the output end of the driving mechanism 200. The driving mechanism 200 is configured to drive the cleaning shovel to move relative to the basin body 100. During the cleaning process, the driving mechanism 200 drives the cleaning shovel to move in the basin body 100, and the cleaning shovel scoops up feces and dirty cat litter, thereby cleaning the cat litter box.

[0072] In the cat litter box of the present invention, a flat first connecting end 11 is provided on the connecting frame 1, a flat second connecting end 21 is provided on the shovel body 2, and a fixing groove 31 is provided on the fixing seat 3 that runs through the first direction, so that the first connecting end 11 and the second connecting end 21 can be clamped in the fixing groove 31. Since the ends are flat, the fixing groove 31 limits the first connecting end 11 and the second connecting end 21 to rotate around their own axes; at the same time, convex ridges 32 are respectively provided at both ends of the second direction of the fixing seat 3, and the second direction is perpendicular to the first direction. Hook structures 41 are provided on opposite sides of the movable block 4. When the two hook structures 41 correspond to the hooks 32 one by one, the movable block 4 can slide relative to the fixing seat 3, and the fixing seat 3 and the movable block 4, one is provided with a first positioning protrusion 33, and the other is provided with a first positioning groove. When the movable block 4 slides to the notch of the cover fixing groove 31, the first positioning protrusion 33 is clamped in the first positioning groove, so that the first connecting end and the second connecting end are locked between the movable block 4 and the fixed seat 3, and the hook structure 41 is hooked on the ridge 32 to form a mechanical locking structure. The structure is direct and firm, so that the shovel body 2 can remain stable regardless of whether it is used in a static or dynamic environment, and the connection method of the hook structure 41 and the ridge 32 is durable, with a small risk of damage, and the clamping force on the shovel body 2 is not easy to weaken. Even if it is disassembled many times and used for a long time, the installation stability of the shovel body 2 can be maintained.

[0073] In this embodiment, the steps for installing the cleaning shovel on the cat litter box are as follows:

[0074] First, snap the first connecting terminal 11 into the fixing slot 31;

[0075] Then, the connecting piece 5 is passed through to connect the first connecting end 11 and the fixing base 3 together;

[0076] Next, snap the second connecting terminal 21 into the fixing slot 31;

[0077] Next, push the movable block 4 to slide on the fixed base 3 until the movable block 4 completely covers the notch of the fixed slot 31;
