Description

Technical Field

[0001] This utility model relates to the field of cat litter box technology, and in particular to a rolling support drive mechanism and a pet feces collection device. Background Technology

[0002] A litter box is a special container that provides a space for cats to eliminate waste. It's an essential item in a cat's daily life, primarily used to hold cat litter and facilitate the cat's natural behavior of burying its excrement. After a cat defecates, feces combine with the litter to form clumps. To facilitate cleaning, tools such as sieves or shovels are typically used to manually separate the clumps from the clean litter. While these methods achieve basic waste removal, manual operation requires time and effort and may not completely remove all clumps of feces.

[0003] Currently, such as Figure 1 As shown, Chinese utility model patent CN221634695U discloses a bidirectional collection device for pet feces, including a litter box 1, a collection chamber 2, and a grid 3.

The grid 3 can reciprocate within the litter box 1 to collect litter clumps into one or both collection chambers 2, avoiding the litter clump collection dead zones that exist with the unidirectional movement of the grid 3, resulting in more thorough cleaning of the litter clumps. However, since the drive block is in direct contact with the main body of the litter box 1, there is mutual sliding friction between the drive block and the litter box 1 during device operation. This friction not only generates significant frictional force, increasing energy consumption, but also produces noise and hinders the flexible reversal of the grid 3, affecting the overall operating effect and user experience of the device.

[0032] Combination Figure 2 And as Figure 3As shown, in order to facilitate assembly, in some embodiments, the lower rolling support 62 comprises a rolling wheel, a protrusion is provided on the connecting piece 61, the rolling wheel is rotatably sleeved on the protrusion, the rolling wheel can be rolling matched with the bottom plate 5 and can reciprocate along the two sides of the litter box 1; by sleeving the rolling wheel on the protrusion of the connecting piece 61, a direct and simple assembly method is formed, without the need for additional complex fixing structure, the matching position of the rolling wheel and the protrusion is fixed and clear, which helps to improve the assembly accuracy, makes the contact position of the rolling wheel and the bottom plate 5 consistent, makes the assembly process more convenient, saves time and process; At the same time, the design of the rolling wheel is particularly flexible when the guide piece 63 changes direction at both ends, it can smoothly transition without jamming, ensuring the smoothness of the entire drive system during the reversing process.

[0034] In other embodiments, the guide piece 63 comprises a guide rail, the guide rail is symmetrically arranged on the bottom of the litter box 1 along the outside of the two sides of the litter box 1, and the lower rolling support 62 can roll along the guide rail; wherein the precise positioning of the guide rail structure makes the movement direction of the lower rolling support 62 clear, accurately keeps the rolling support assembly 6 traveling on the specified track, avoids the problem of the rolling support assembly 6 deviating from the path, thereby improving the running accuracy of the device, and effectively avoiding jamming during reversing, ensuring smooth transition and improving the reversing stability and flexibility of the device.

[0036] Since the lower rolling support 62 is located at the bottom of the device, it mainly bears the weight of the connecting piece 61 and the grille 3 above it. The weight of these components is transferred to the base plate 5 through the lower rolling support 62. Simultaneously, the rolling support assembly 6, driven by the drive assembly 7, drives the grille 3 to reciprocate. During its movement, the lower rolling support 62 also needs to overcome friction to push the grille 3 to complete the cleaning process. Therefore, the lower rolling support 62 needs to withstand a certain amount of load. Thus, as... Figure 3 As shown, in order to improve the supporting force of the rolling support assembly 6 and enhance the overall structural stability, in some embodiments, the rolling support assembly 6 further includes an auxiliary support member 65.

The auxiliary support member 65 is located between the upper and lower rolling support members 62, forming a multi-point support structure. The auxiliary support member 65 shares part of the load of the connecting member 61 and the grille 3, thereby reducing the pressure on the lower rolling support member 62, reducing its wear risk during long-term use, and improving the stability of the rolling support drive mechanism in both vertical and lateral directions. This reduces the shaking and displacement of the rolling support assembly 6 during the use of the litter box 1, and extends the service life of the device. Specifically, the auxiliary support 65 includes a support protrusion. One of the sidewalls of the litter box 1 or the connector 61 has a support protrusion along the direction of the reciprocating motion of the rolling support assembly 6, while the other has a support groove. The support protrusion and the support groove slide against each other. The cooperation between the support protrusion and the support groove forms a precise and stable support system, helping to evenly distribute the load on the lower rolling support 62 to different components, reducing the burden on the lower rolling support 62. The auxiliary support 65, through its cooperation with the sidewall of the litter box 1 and the connector 61, effectively shares the load borne by the lower rolling support 62, reducing localized pressure concentration. Furthermore, the structural design of the support protrusion and the support groove simplifies the assembly process. During assembly, the support protrusion and the support groove can precisely align, eliminating the need for additional complex fixing structures and reducing errors and time consumption during assembly.

[0037] In order to improve the driving efficiency, in some embodiments, the driving assembly 7 comprises a driving motor and a transmission member, the output end of the driving motor is connected with the transmission member, and the transmission member is connected with the connecting piece 61 to drive the rolling support to reciprocate along the two sides of the litter box 1; the driving motor provides stable power output, and the power is transmitted through the transmission member, which can effectively convert the rotary motion of the motor into the reciprocating linear motion required by the rolling support, and such mechanism can realize precise speed control, ensure the smooth and consistent movement of the rolling support along the two sides of the litter box 1, and improve the overall working efficiency. The driving motor can be but is not limited to a direct current driving motor, which is not limited here.
