Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pet hygiene equipment technology, and in particular relates to an automatic cleaning device for pet excrement. Background Technology
[0002] With the continuous improvement of socio-economic conditions and the growth of residents' disposable income, the public's demand for quality of life and emotional companionship has increased significantly, and the proportion of family companion pets, especially pet cats, has shown an exponential upward trend.
[0003] Currently, due to the objective limitations of the fast-paced lifestyle of modern urban dwellers, most pet owners find it difficult to dedicate sufficient time each day to handling feline waste, leading to a surge in demand for intelligent pet hygiene equipment.
[0004] The current mainstream solution is a closed cat litter box with built-in absorbent materials (such as silica gel and bentonite). While this achieves basic waste consolidation, it still requires regular manual sieving of old litter and refilling with new litter, a process that is both labor-intensive and time-consuming. More importantly, the organic metabolic products retained in the box can easily breed Gram-negative bacteria and odor-producing microorganisms (such as Proteus and Clostridium) in a humid and hot environment, leading to excessive concentrations of volatile sulfur compounds (VSCs), which in turn deteriorates air quality in the living environment and increases the risk of zoonotic disease transmission. Utility Model Content
[0005] The purpose of this utility model embodiment is to provide an automatic pet excrement cleaning device, which aims to solve the technical problems of low cleaning efficiency, high hygiene risks and complicated operation of existing cleaning equipment.
[0006] To achieve the above objectives, the present invention provides the following technical solution.
[0007] An automatic pet waste cleaning device includes:
[0008] The upper hull is an open structure. The bottom plate of the upper hull has a discharge port, and a support sleeve is fixedly installed on the bottom plate of the upper hull. Two partitions are fixedly installed on the outer circumference of the support sleeve, and the discharge port is located directly below the area between the two partitions.
[0009] The cleaning net is detachably and fixedly installed on the top of the drive shaft;
[0010] A sector-shaped baffle is fixedly installed on a support ring sleeve, which is slidably sleeved on the drive shaft along the axial direction.
[0011] A reciprocating lifting component is used to drive the transmission shaft to move up and down reciprocally. The bottom end of the transmission shaft is connected to the output shaft of a vertical motor, which is fixedly mounted on a support. The support is connected to the reciprocating lifting component.
[0012] Furthermore, the cleaning net adopts a grid structure composed of multiple horizontal bars and multiple vertical bars. Each vertical bar of the grid structure is equipped with a cleaning foot at the bottom end, so that when the cleaning net moves in the upper chamber, it lifts the excrement in the sand from the sand to the surface of the sand for cleaning. The excrement is finally pushed to the discharge outlet for discharge.
[0013] Furthermore, the reciprocating lifting component includes a turntable, one side of which is provided with an outer guide groove and an inner guide groove arranged coaxially. The turntable is driven and connected to the output shaft of a transverse motor along the axis, and the transverse motor drives the turntable to rotate. The transverse motor is fixedly installed on the lower surface of the bottom plate of the upper cabin.
[0014] The bottom end of the outer guide groove is connected to the bottom end of the inner guide groove.
[0015] Furthermore, the support is fixedly installed at the top of the cam rod, and a cooperating head is rotatably provided on one side of the bottom end of the cam rod. The cooperating head slides against the guide groove of the turntable and has a rhomboid structure.
[0016] Furthermore, the bottom inner ring of the upper cabin is provided with a guide ring groove that matches the arc end of the fan-shaped baffle, which guides the fan-shaped baffle during movement.
[0017] Furthermore, the bottom of the upper chamber is mounted on the lower chamber, and the lower chamber is provided with a pull-out drawer for collecting excrement. The drawer is located directly below the discharge outlet. When the fan-shaped baffle moves to block the discharge outlet, the fan-shaped baffle is located in the area between the discharge outlet and the drawer.
[0018] Furthermore, an electric heating tube is embedded inside the bottom plate of the upper cabin.
[0019] Compared with the prior art, the automatic pet excrement cleaning device of this utility model has the following beneficial effects:
[0020] First, the vertical motor drives the transmission shaft to rotate, causing the cleaning net to move within the upper chamber. This lifts the excrement from the sand to the surface for cleaning, and the excrement is ultimately pushed to the discharge outlet for discharge.
[0021] Secondly, the reciprocating lifting component of this utility model allows the sweeping net to switch back and forth between two height states, enabling the sweeping net to move up and down reciprocally, which facilitates the cleaning of excrement in the sand and makes the torque of the sweeping net and the drive shaft more stable, thereby improving the stability of the operation and the transmission efficiency.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0033] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0034] In one embodiment of this utility model, an automatic pet excrement cleaning device is provided. This automatic cleaning device can be used to clean pet excrement in litter, such as cleaning cat excrement in cat litter.
[0035] For details, please refer to Figures 1-3 The automatic cleaning device provided in this embodiment includes an upper chamber 1, which is an open structure. The bottom plate of the upper chamber 1 has a discharge port 5, and a support sleeve 31 is fixedly installed on the bottom plate of the upper chamber 1. Two partitions 3 are fixedly installed on the outer peripheral surface of the support sleeve 31, and the discharge port 5 is located directly below the area between the two partitions 3.
[0036] In practice, the sand is placed in the upper compartment 1 for the pet to defecate.
[0037] like Figures 1-6 As shown, the automatic cleaning device provided in this embodiment further includes:
[0038] The cleaning net 7 is fixedly installed on the top of the drive shaft 6. The cleaning net 7 adopts a grid structure composed of multiple horizontal bars and multiple vertical bars. Each vertical bar of the grid structure is provided with a cleaning foot 71 at the bottom end. When the cleaning net 7 moves in the upper chamber 1, it lifts the excrement in the sand from the sand to the surface of the sand for cleaning. The excrement is finally pushed to the discharge outlet 5 for discharge.
[0039] Reference Figure 7 In another embodiment of this utility model, the bottom surface of the cleaning foot 71 is integrally formed with a pointed cone block 72, the tip of the pointed cone block 72 facing downward, so that the cleaning foot 71 can be pressed into the sand.
[0040] Furthermore, it also includes a sector-shaped baffle 10, which is fixedly installed on the support ring sleeve 11. The support ring sleeve 11 is slidably sleeved on the transmission shaft 6 along the axial direction. That is, the support ring sleeve 11 can only slide along the axial direction of the transmission shaft 6. When the transmission shaft 6 rotates, it drives the support ring sleeve 11 to rotate synchronously, that is, it drives the sector-shaped baffle 10 to perform circumferential motion around the axis of the transmission shaft 6.
[0041] In addition, it also includes a reciprocating lifting component, which is used to drive the drive shaft 6 to move up and down reciprocally;
[0042] The bottom end of the transmission shaft 6 is driven and connected to the output shaft of the vertical motor 12, which is fixedly mounted on the support 14; the support 14 is connected to the reciprocating lifting component.
[0043] like Figures 4-6As shown, in one implementation of this disclosure, the reciprocating lifting component includes a turntable 16. One side of the turntable 16 is provided with an outer guide groove 161 and an inner guide groove 162 arranged coaxially. The turntable 16 is driven to rotate by the output shaft of the transverse motor 17 along the axis. The transverse motor 17 drives the turntable 16 to rotate. The transverse motor 17 is fixedly installed on the lower surface of the bottom plate of the upper cabin 1.
[0044] The bottom end of the outer guide groove 161 is connected to the bottom end of the inner guide groove 162;
[0045] The support 14 is fixedly installed on the top of the cam rod 13, and the bottom end of the cam rod 13 is rotatably provided with a cooperating head 15;
[0046] In this embodiment of the utility model, the cooperating head 15 slides against the guide groove of the turntable 16. The cooperating head 15 has a rhomboid structure. The length of the long diagonal of the cooperating head 15 is greater than the width of the guide groove (including the inner guide groove 162 and the outer guide groove 161). The widths of the inner guide groove 162 and the outer guide groove 161 are equal.
[0047] During the rotation of the turntable 16, when the cooperating head 15 slides within the outer guide groove 161, the cleaning net 7 at the top of the drive shaft 6 remains at the first height. When the cooperating head 15 moves from the outer guide groove 161 into the inner guide groove 162, the cleaning net 7 moves to the second height, which is lower than the first height. In other words, the reciprocating lifting component provided in this embodiment causes the cleaning net 7 to change from the state at the first height to the state at the second height. When the rotation speed of the turntable 16 of the reciprocating lifting component is increased, the cleaning net 7 can move in a reciprocating cycle, allowing the cleaning net 7 to periodically insert into and pull out of the sand. Combined with the movement of the cleaning net 7 in the sand area, the excrement in the sand can be cleaned to the surface of the sand, making it easier for the cleaning net 7 to insert into the sand to clean the excrement.
[0048] Furthermore, after the excrement in the sand is cleaned to the surface, the cleaning net 7 is moved up to the first height using a reciprocating lifting device. The bottom of the cleaning net 7 at the first height is flush with the upper surface of the partition 3. Then, the vertical motor 12 drives the transmission shaft 6 to move the cleaning net 7, cleaning the excrement on the surface and pushing it to the discharge outlet 5 for discharge.
[0049] It should be noted that although the fan-shaped baffle 10 of this embodiment moves with the movement of the cleaning net 7, it does not affect the discharge outlet 5 from discharging the excrement into the drawer 4. This is because when the cleaning net 7 moves on the sand, the fan-shaped baffle 10 does not block the discharge outlet 5. When the cleaning net 7 is directly above the discharge outlet 5, the cleaning work stops. The fan-shaped baffle 10 plays a role in sealing the discharge outlet 5, preventing odors from escaping from the drawer 4.
[0050] In addition, the vertical motor 12 and the horizontal motor 17 of this utility model are both servo motors with forward and reverse rotation functions in conventional technology. They are purchased components and can be used with a PLC controller to control them to perform precise actions. The specific control system and PLC controller are known to those skilled in the art and are not limited here.
[0051] Please continue to refer to Figure 1 and Figure 2 The bottom inner ring of the upper cabin 1 is provided with a guide ring groove 9 that matches the arc end of the fan-shaped baffle 10, which guides the fan-shaped baffle 10 during the movement.
[0052] The bottom of the upper chamber 1 is mounted on the lower chamber 2, and the lower chamber 2 is provided with a pull-out drawer 4 for collecting excrement. The drawer 4 is located directly below the outlet 5. When the fan-shaped baffle 10 moves to block the outlet 5, the fan-shaped baffle 10 is located in the area between the outlet 5 and the drawer 4.
[0053] Please continue to refer to Figure 2 The bottom plate of the upper chamber 1 is embedded with an electric heating tube 8. The electric heating tube 8 is used to sterilize the excrement at high temperature and accelerate drying. On the other hand, it can also be used to keep pets warm when the environment is low. Considering safety during operation, the heating temperature of the electric heating tube 8 is controlled between 20 degrees Celsius and 35 degrees Celsius.
[0054] Preferably, the cleaning net 7 of this utility model has a detachable structure for easy maintenance; for example, the cleaning net 7 is fixedly connected to the drive shaft 6 by bolt connection.
[0055] The reciprocating lifting component of this utility model not only makes the torque of the sweeping net 7 and the drive shaft 6 more stable, improving the stability of the work and the transmission efficiency, but also the combination of up-and-down reciprocating motion and horizontal motion makes the cleaning and filtration of excrement more thorough, thus improving work efficiency.
[0056] This invention, by adding an electric heating element 8, disinfects excrement at high temperatures, reducing the risk of deteriorating air quality in the living environment and the spread of zoonotic diseases. It also accelerates the drying of excrement, improves cleaning efficiency, and can be used for heating and keeping warm in winter to protect the health of pets.
[0057] The above solutions are merely illustrative examples of preferred embodiments, but are not limited thereto. When implementing this invention, appropriate substitutions and / or modifications can be made according to the user's needs.
[0058] The number of devices and processing scale described herein are for the purpose of simplifying the description of this utility model. Applications, modifications, and variations of this utility model will be readily apparent to those skilled in the art.
[0059] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
