Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to an automatic cat litter box with motor shock absorption function. Background Technology

[0002] Currently, in automatic litter boxes with motor vibration damping function on the market, a fixed bracket or mounting box is set up to install the drive motor that drives the litter bin to rotate. Then, a vibration damping structure is set between the housing of the mounting base of the automatic litter box with motor vibration damping function and the fixed bracket or mounting box, thereby reducing the vibration of the drive motor when it is working.

[0003] However, this makes the connection structure between the housing and the mounting bracket or box, as well as the structure of the mounting bracket or box itself, quite complex. Furthermore, since there is no vibration damping structure between the drive motor and the mounting bracket or box, vibrations in the drive motor will cause the mounting bracket or box to vibrate, resulting in abnormal noise and affecting the user experience. On the other hand, the mounting bracket or box occupies a significant amount of space within the housing, which is detrimental to the miniaturization design of automatic litter boxes with motor vibration damping. Utility Model Content

[0004] The main purpose of this invention is to provide an automatic litter box with motor vibration damping function, aiming to solve at least one of the above-mentioned problems.

[0005] To achieve the above objectives, the present invention proposes an automatic litter box with motor vibration damping function, comprising:

[0006] The mounting base has an opening in the middle that extends through the top and bottom of the mounting base, and the mounting base has a mounting cavity on at least one side in the left-right direction;

[0007] A sand bin, which is rotatably connected to the top of the mounting base;

[0008] A waste collection chamber is connected to the bottom of the mounting base, and the opening connects the sand chamber and the waste collection chamber.

[0009] A drive module includes a drive motor for driving the sand chamber to rotate about a first axis. The drive motor is mounted on the mounting cavity near the side wall of the sand chamber via fasteners. The first axis extends in a left-right direction.

[0010] The shock absorption module is sandwiched between the side wall of the mounting cavity and the fastener, and between the side wall of the mounting cavity and the drive motor.

[0011] In one embodiment, the mounting cavity has a plurality of fixing holes on the side wall near the sand hopper, and a plurality of fasteners are provided accordingly. The fasteners pass through the fixing holes to connect the side wall of the mounting cavity and the drive motor.

[0012] In one embodiment, the damping module includes a damping ring, the outer peripheral wall of which is provided with an assembly groove, and two opposite sidewalls of the assembly groove abut against opposite end faces of the fixing hole.

[0013] In one embodiment, the fastener includes a bolt, the bolt includes a nut and a stud, the drive motor has a threaded hole, the stud includes an abutment section and a threaded section, the abutment section abuts against the shock absorber ring, and the threaded section has an external thread that matches the internal thread in the threaded hole.

[0014] In one embodiment, the diameter of the abutment section is larger than the diameter of the threaded section.

[0015] In one embodiment, the length of the abutment section is less than the thickness of the damping ring.

[0016] In one embodiment, the shock absorber is made of silicone or rubber.

[0017] In one embodiment, a fixing post protrudes from one side of the drive motor near the sand bin, and the threaded hole is located on the fixing post.

[0018] In one embodiment, a mounting area is provided on the side wall of the mounting cavity, the mounting area being connected to the drive motor, and the wall thickness of the mounting area being greater than the wall thickness of the remaining areas within the mounting cavity.

[0019] In one embodiment, the drive module further includes a transmission gear connected to the output shaft of the drive motor. The transmission gear is located outside the mounting cavity and is disposed between the mounting cavity and the sand chamber.

[0020] The technical solution of this utility model allows the drive motor to be fixed to the side wall of the mounting cavity by fasteners, which simplifies the installation structure of the drive motor and reduces the volume required for installing the drive motor, thereby helping to reduce the volume of the mounting base and thus reducing the volume of the automatic litter box with motor shock absorption function.

[0021] The fasteners and drive motor are isolated by a shock-absorbing module on the side wall of the mounting cavity. That is, the drive motor and the fasteners only contact the shock-absorbing module, and the shock-absorbing module then contacts the side wall of the mounting cavity. This achieves complete isolation between the side wall of the mounting cavity and the drive motor and fasteners, which can effectively reduce the vibration transmitted to the side wall of the mounting cavity when the drive motor is working, thereby avoiding abnormal noise when the drive motor is working.

[0037] This utility model proposes an automatic litter box with motor vibration damping function.

[0038] Please see Figures 1 to 5 In one embodiment of this utility model, the automatic litter box with motor vibration damping function includes:

[0039] Mounting base 100, the middle of which is provided with an opening 12 that penetrates the top and bottom of the mounting base 100, and the mounting base 100 is provided with a mounting cavity 11 on at least one side in the left-right direction;

[0040] A sand bin (not shown in the figure) is rotatably connected to the top of the mounting base 100;

[0041] The waste collection chamber (not shown in the figure) is connected to the bottom of the mounting base 100, and the opening 12 can connect the sand chamber and the waste collection chamber.

[0042] Drive module 200 includes drive motor 21, which drives the sand chamber to rotate about a first axis. Drive motor 21 is mounted on the side wall of mounting cavity 11 near the sand chamber by fasteners 400. The first axis extends in a left-right direction.

[0043] The shock absorption module 300 is sandwiched between the side wall of the mounting cavity 11 and the fastener 400, and between the side wall of the mounting cavity 11 and the drive motor 21.

[0044] The technical solution of this utility model allows the drive motor 21 to be fixed to the side wall of the mounting cavity 11 by fasteners 400, which simplifies the installation structure of the drive motor 21 and reduces the volume required for its installation, thus helping to reduce the volume of the mounting base 100 and consequently the volume of the automatic litter box with motor vibration damping function. A vibration damping module 300 is provided on the side wall of the mounting cavity 11 to isolate the fasteners 400 and the drive motor 21. That is, the drive motor 21 and the fasteners 400 only contact the vibration damping module 300, and the vibration damping module 300 then contacts the side wall of the mounting cavity 11, achieving complete isolation between the side wall of the mounting cavity 11 and the drive motor 21 and the fasteners 400. This effectively reduces the vibration transmitted to the side wall of the mounting cavity 11 when the drive motor 21 is working.

[0045] In one embodiment, the mounting cavity 11 has multiple fixing holes 111 on its side wall near the sand hopper, and multiple fasteners 400 are correspondingly provided. The fasteners 400 pass through the fixing holes 111 to connect the side wall of the mounting cavity 11 and the drive motor 21, so as to securely fix the drive motor 21 to the side wall of the mounting cavity 11. In other embodiments, the side wall of the mounting cavity 11 may also have a buckle, and the fasteners 400 may be connected to the side wall of the mounting cavity 11 through the buckle.

[0046] In one embodiment, the damping module 300 includes a damping ring 31. The outer peripheral wall of the damping ring 31 has a mounting groove 311. Two opposing sidewalls of the mounting groove 311 abut against opposite end faces of the fixing hole 111 to fix the damping ring 31 to the sidewall of the mounting cavity 11. When the fastener 400 passes through the fixing hole 111, the fastener 400 abuts against the inner wall of the damping ring 31, and the drive motor 21 abuts against the end wall of the damping ring 31 located within the mounting cavity 11. At this time, the damping ring 31 can isolate the fastener 400 and the drive motor 21 from the sidewall of the mounting cavity 11. In other embodiments, the damping module 300 may also include a flexible damping element. The flexible damping element can be inserted into the fixing hole 111 along with the fastener 400, filling the gap between the fixing hole 111 and the fastener 400, and filling the gap between the sidewall of the mounting cavity 11 and the drive motor 21.

[0047] In one embodiment, the fastener 400 includes a bolt 41, which includes a nut 411 and a stud 412. The drive motor 21 has a threaded hole 212. The stud 412 includes an abutment section 413 and a threaded section 414. The abutment section 413 abuts against the damping ring 31, and the threaded section 414 has an external thread 415 that matches the internal thread in the threaded hole 212. That is, the abutment section 413 does not have an external thread 415. Since the drive motor 21 transmits vibration to the fastener 400 during operation, the fastener 400 will vibrate. When the abutment section 413 does not have an external thread 415, the inner wall of the damping ring 31 can be prevented from being worn by the vibrating external thread 415, thereby extending the service life of the damping ring 31. It should be noted that when the fastener 400 is inserted into the fixing hole 111 and assembled with the drive motor 21, the nut 411 of the fastener 400 abuts against the end wall of the shock-absorbing ring 31 located outside the mounting cavity 11, thereby preventing vibration from being transmitted from the nut 411 to the side wall of the mounting cavity 11. In other embodiments, the end of the fastener 400 near the drive motor 21 may be provided with an elastic buckle, and the drive motor 21 may be provided with a corresponding slot, so that the buckle can be inserted into the slot to complete the assembly of the fastener 400 and the drive motor 21.

[0048] In one embodiment, the diameter of the abutment section 413 is larger than the diameter of the threaded section 414. Since the damping ring 31 needs to be assembled with the fixing hole 111 first, and then the fastener 400 is passed through the fixing hole 111, setting the diameter of the threaded section 414 smaller than that of the abutment section 413 during this process avoids the threaded section 414 scratching the inner wall of the damping ring 31. In other embodiments, the diameter of the threaded section 414 can be equal to the diameter of the abutment section 413.

[0049] In one embodiment, the length of the abutment section 413 is less than the thickness of the damping ring 31. That is, when the threaded section 414 is fully screwed into the threaded hole 212, that is, when the fastener 400 is assembled with the drive motor 21, the nut 411 and the drive motor 21 together compress the damping ring 31 to pre-tighten it, thereby preventing the drive motor 21 and the fastener 400 from shaking on the side wall of the mounting cavity 11 after assembly. In other embodiments, the length of the abutment section 413 may be equal to the thickness of the damping ring 31.

[0050] In one embodiment, the damping ring 31 is made of silicone or rubber to make it elastic, capable of absorbing and attenuating vibrations transmitted by the self-driven motor 21 through elastic deformation. In other embodiments, the damping ring 31 may be made of an elastic metal to allow for elastic deformation in the radial and / or axial directions.

[0051] In one embodiment, a fixing post 211 protrudes from one side of the drive motor 21 near the sand chamber, and a threaded hole 212 is provided in the fixing post 211. The end face of the fixing post 211 can abut against the end wall of the shock absorber 31 located in the mounting cavity 11. In other embodiments, the fixing post 211 may not be provided.

[0052] In one embodiment, a mounting area 112 is provided on the side wall of the mounting cavity 11. The mounting area 112 is used to connect with the drive motor 21, and the wall thickness of the mounting area 112 is greater than the wall thickness of the rest of the area within the mounting cavity 11. This is to strengthen the side wall of the mounting area 112 so as to stably support the drive motor 21 for a long time. In other embodiments, the side wall of the mounting area 112 may also be provided with multiple reinforcing ribs.

[0053] In one embodiment, the drive module 200 further includes a transmission gear 22 connected to the output shaft of the drive motor 21. The transmission gear 22 is located outside the mounting cavity 11 and is positioned between the mounting cavity 11 and the sand chamber. The transmission gear 22 can transmit torque to the sand chamber, thereby driving the sand chamber to rotate around the first axis, so that the fecal clumps in the sand chamber roll from the opening 12 into the collection chamber. Further, a receiving gear is provided at the end of the sand chamber near the drive motor 21, and the receiving gear meshes with the corresponding transmission gear 22. It can be understood that the drive motor 21 drives the rotation of the sand chamber through the transmission action of the transmission gear 22 and the receiving gear. In other embodiments, the rotating gear and the receiving gear can also be connected by a synchronous belt.

[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
