DETAILED DESCRIPTION

[0048] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0049] In the description of the present application, it should be noted that the orientations or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the modules or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the specification of the present application herein is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0051] Reference Figures 1-9The utility model provides an open type automatic cleaning cat litter basin, including the frame 1 of rectangle, mobile device 3 and cat litter harrow 4, the frame 1 is sequentially provided with cat litter holding space 11 and excrement drop 12 along its length direction, the cat litter holding space 11 is placed with the basin body 2 of the cat litter that can be separated and is used to receive, the mobile device 3 is set in the side of frame 1 and can reciprocatingly move along the length direction of frame 1, preferably, the mobile device 3 is provided with two groups and is respectively located in both sides in the width direction of frame 1, the cat litter harrow 4 is transversely placed on frame 1 and both ends are respectively rotationally arranged on two mobile devices 3, wherein, the mobile device 3 can drive cat litter harrow 4 to move up and down.

[0052] Therefore, when the mobile device 3 drives the cat litter harrow 4 to move along the length direction of the basin body 2 from one end away from the excrement drop 12 to one end close to the excrement drop 12 on the basin body 2, the cat litter harrow 4 can rake the excrement out of the cat litter; then the cat litter harrow 4 is driven to move up by the mobile device 3 to push the excrement into the excrement drop 12.

[0053] Therefore, by using the automatic cleaning cat litter basin of the utility model, the mobile device 3 can not only drive the cat litter harrow 4 to move along the length direction of the frame 1, but also drive the cat litter harrow 4 to move up and down; therefore, after driving the cat litter harrow 4 to run from one end to the other end of the cat litter holding space 11 to rake the excrement out of the cat litter, the cat litter harrow 4 can be driven to move up by the mobile device 3 to push the excrement into the excrement drop 12, so that it is not necessary to return to the initial position of the cat litter basin and rotate the cat litter harrow 4 to a large angle to make the excrement fall, like the traditional cat litter harrow 4. Therefore, the automatic cleaning cat litter basin of the utility model can use the up-and-down track to push the excrement into the excrement drop 12, so that it is not necessary to additionally set a rotating mechanism, which not only has a simple structure, but also has a relatively simple cleaning movement track of the cat litter harrow 4 and a relatively low control requirement of the system.

[0054] In the utility model embodiment, further include the bottom frame 6 that sets in the frame 1 bottom, the bottom frame 6 is equipped with the drawer 61 that can be drawn and the collection of excrement box 62, the drawer 61 is located below the basin body 2 and is used to store sundries, the collection of excrement box 62 is located below the excrement drop 12 and is used to collect excrement.

[0055] The first inclined guide surface 21 is formed on one end of the basin 2 away from the feces dropping port 12, and the second inclined guide surface 22 is formed on the other end of the basin 2 close to the feces dropping port 12. Meanwhile, the cat litter rake 4 is obliquely arranged. Therefore, in order to ensure that the cat litter rake 4 does not interfere with the basin 2 when moving up or down, and at the same time ensure that the cat litter rake 4 can completely filter the cat litter in the basin 2, when the moving device 3 drives the cat litter rake 4 to move down into the basin 2, the moving device 3 will drive the cat litter rake 4 to move forward to make the cat litter rake 4 move obliquely downward, so that the cat litter rake 4 can enter the basin 2 along the first inclined guide surface 21, which not only avoids interference with the basin 2, but also ensures that the end of the cat litter rake 4 is located at the end of the basin 2 when the cat litter rake 4 enters the basin 2. Thus, when the cat litter rake 4 is driven to move along the length direction of the basin 2 to the other end of the basin 2, the cat litter rake 4 can completely filter the cat litter to filter out the feces. Then, when the moving device 3 drives the cat litter rake 4 to move up, the moving device 3 will drive the cat litter rake 4 to move forward to make the cat litter rake 4 move obliquely upward, so that the cat litter rake 4 can drive the feces to move obliquely upward along the second inclined guide surface 22 and finally be pushed into the feces dropping port 12.

[0056] It should be noted that in other embodiments, the first inclined guide surface 21 and / or the second inclined guide surface 22 in the basin 2 can be replaced by vertical surfaces, and at this time the cat litter rake 4 can be adjusted to be vertically arranged or slightly obliquely arranged according to actual conditions, so as to match the two ends of the basin 2 to complete the cleaning of the cat litter, which is not limited here.

[0057] Referring to Figures 3-5 The moving device 3 comprises a base 31, a lifting seat 32 movably arranged on the base 31, and a first driving device 33 arranged on the base 31 and driving the lifting seat 32 to move up and down. Preferably, the first driving device 33 is a lead screw motor, and the lifting seat 32 is slidingly arranged on the lead screw of the lead screw motor. Thus, when the lead screw motor drives the lead screw to rotate, the lifting seat 32 can be driven to move up and down along the lead screw. In addition, the end of the cat litter rake 4 is also provided with a rotating head 41 rotatingly arranged on the lifting seat 32, which can be driven to move up and down to realize the lifting and lowering movement of the cat litter rake 4 when the lifting seat 32 moves up and down.

[0058] Of course, it should be noted that in other embodiments, the first driving device 33 can also be arranged on the lifting seat 32, and in this case, the first driving device 33 is a driving motor, the output shaft of the driving motor is connected with a gear, and the base 31 is provided with a rack arranged vertically and in meshing transmission with the gear; thus, when the driving motor drives the gear to rotate, the lifting seat 32 can be moved up and down along the rack, and the lifting seat 32 can be driven to move up and down relative to the base 31, which can also achieve the same technical effect, and thus is not limited here.

[0059] In addition, the base 31 is also provided with a second driving device 35 for driving the base 31 to move reciprocatingly along the length direction of the frame 1; preferably, the second driving device 35 is a driving motor, and the output shaft of the driving motor is sleeved with a gear 38; the bottom of the frame 1 is provided with a second rack 13 extending along the length direction of the frame 1, and the gear 38 is in meshing transmission with the second rack 13. Thus, when the second driving device 35 drives the gear 38 to rotate, the gear 38 can be driven to slide on the second rack 13, and the moving device 3 and the cat litter rake 4 can be driven to move forward and backward along the length direction of the frame 1 as a whole.

[0060] Referring back to Figure 4 The bottom of the frame 1 is provided with a limiting guide rail 14 extending along the length direction of the frame 1, and the limiting guide rail is provided with a limiting sliding groove, and the base 31 is provided with a limiting sliding block slidingly clamped in the limiting sliding groove and used for limiting the base 31 from moving along the width direction and the height direction of the frame 1. Specifically, the limiting guide rail 14 is provided with a first limiting sliding groove 141 and a second limiting sliding groove 142 extending along the length direction of the limiting guide rail and respectively located at the bottom and the side; the base 31 is also provided with a first limiting sliding block 311 slidingly clamped in the first limiting sliding groove 141 and a second limiting sliding block 312 slidingly clamped in the second limiting sliding groove 142, the first limiting sliding block 311 is used for limiting the base 31 from moving along the width direction of the frame 1, and the second limiting sliding block 312 is used for limiting the base 31 from moving along the height direction of the frame 1.

[0061] Thus, by arranging the limiting guide rail 14 at the bottom of the frame 1 and arranging the first limiting sliding block 311 and the second limiting sliding block 312 on the base 31, the movement of the base 31 along the width direction of the frame 1 and along the height direction of the frame 1 can be limited, and thus it is ensured that the base 31 can only move reciprocatingly along the length direction of the frame 1.

[0062] Referring back to Figure 5The moving device 3 further comprises a guide assembly 37 arranged between the base 31 and the lifting seat 32, the guide assembly 37 comprises a guide rod 371 arranged on the base 31 and a guide block 372 arranged on the lifting seat 32 and sliding on the guide rod 371. Thus, when the first driving device 33 drives the lifting seat 32 to move up and down relative to the base 31, the guide block 372 can be driven to reciprocate along the axis direction of the guide rod 371, thereby improving the stability of the lifting seat 32 moving up and down.

[0063] Further, the moving device 3 is further provided with a transmission assembly which is in transmission cooperation with the cat litter rake 4, when the moving device 3 drives the cat litter rake 4 to move up and down, the cat litter rake 4 can be synchronously driven to rotate through the transmission assembly. Preferably, the transmission assembly is a slide rail slide rod assembly 34 arranged between the base 31 and the rotating head 41, the slide rail slide rod assembly 34 comprises a slide rail plate 341 arranged on the base 31 and a slide rod 342 sliding on the slide rail plate 341, the slide rail plate 341 is provided with at least one slide rail 3411 arranged in a partially inclined manner, one end of the slide rod 342 slides on the slide rail 3411, and the other end of the slide rod 342 is sleeved on the rotating head 41. Preferably, the slide rail 3411 comprises a first vertical section 34111 at a lower height position, a second vertical section 34112 at a higher height position and arranged in a spaced manner with the first vertical section 34111, and an inclined section 34113 respectively communicating the first vertical section 34111 and the second vertical section 34112.

[0064] Thus, when the lifting seat 32 is driven to move up and down, the slide rod 342 can be synchronously driven to slide on the slide rail 3411 and rotate, and then the rotating head 41 is driven to rotate through the slide rod 342 to realize the rotation of the cat litter rake 4.

[0065] Thus, the automatic cleaning cat litter basin of the utility model, when the moving device 3 drives the cat litter rake 4 to move up and down, the cat litter rake 4 can be synchronously driven to rotate through the slide rail slide rod assembly, when the cat litter rake 4 is driven to rise to push the excrement into the excrement dropping port 12, the cat litter rake 4 can be synchronously driven to rotate to push the excrement into the excrement dropping port 12 more conveniently. In addition, when the cat litter rake 4 is stuck with excrement, the cat litter rake 4 can also be driven to move up and down and rotate to shake off the excrement, and further, when the cat litter basin is stacked with cat litter, the lifting and rotating track can also be used to flatten the cat litter stack.

[0066] Referring to Figure 6The mobile device 3 further comprises a positioning structure, which comprises two positioning switches 36 and a bump 3412 for triggering the positioning switches 36. Specifically, the two positioning switches 36 are arranged at different heights on the lifting seat 32, and the slide rail plate 341 is provided with the bump 3412 for triggering the positioning switches 36. Preferably, the positioning switches 36 are micro switches, and the micro switches are provided with contacts and elastic sheets. Thus, when the first driving device 33 drives the lifting seat 32 to lift, the elastic sheets on the two micro switches can be sequentially abutted with the bump 3412, the bump 3412 can drive the elastic sheets to move and contact the contacts to trigger the micro switches, thereby achieving the lifting positioning of the lifting seat 32.

[0067] Of course, in other embodiments, the positions of the positioning switches 36 and the bump 3412 can be interchanged, that is, the two positioning switches 36 are arranged at different heights on the slide rail plate 341, and the bump 3412 is arranged on the lifting seat 32. Thus, when the first driving device 33 drives the lifting seat 32 to lift, the bump 3412 can be sequentially abutted with the two positioning switches 36 and triggered, thereby achieving the lifting positioning of the lifting seat 32, which can also achieve the same technical effect, and thus is not limited here.

[0068] Further, a limiting structure arranged between the rotating head 41 and the slide rod 342 and an elastic member arranged on the rotating head 41 are further included. One end of the elastic member is in abutment with the rotating head 41, and the other end is in abutment with the slide rod 342. Thus, under the elastic force of the elastic member, the rotating head 41 can be driven to rotate and be limited and fixed on the slide rod 342 through the limiting structure, thereby achieving the angle limiting and fixing of the cat litter rake 4.

[0069] The limiting structure comprises a limiting groove 412 arranged on the outer periphery of the rotating head 41 and extending in the circumferential direction, and a limiting block 3421 arranged on the slide rod 342 and slidingly arranged in the limiting groove 412. Preferably, the elastic member is a torsion spring 42, which comprises a torsion spring body and a first torsion arm and a second torsion arm arranged at two ends of the torsion spring body. The torsion spring body is sleeved on the rotating head 41, the rotating head 41 is provided with a clamping groove 411, and the first torsion arm is clamped in the clamping groove 411. The second torsion arm is in abutment with the slide rod 342. Thus, under the elastic force of the torsion spring 42, the rotating head 41 can be driven to rotate and be limited and fixed by the limiting block 3421 on the slide rod 342 through the limiting groove 412 on the rotating head 41.

[0070] Of course, it should be noted that in other embodiments, the positions of the limiting groove 412 and the limiting block 3421 can be interchanged, which can also achieve the same technical effect, and thus is not limited here.

[0071] In addition, it should be noted that in other embodiments, the transmission assembly can also be a rack and pinion assembly 39. Referring to Figure 8 The rack and pinion assembly 39 includes a first rack 391 provided on the base 31 and a gear plate 392 rotatably engaged with the first rack 391, and the other end of the gear plate 392 is sleeved on the rotating head 41. Thus, when the lifting seat 32 is driven to move up and down, the gear plate 392 can be synchronously driven to rotate on the first rack 391, and then the rotating head 41 is driven to rotate by the gear plate 392 to achieve the rotation of the cat litter rake 4, which can also achieve the same technical effect.

[0072] Referring to Figures 1-3 The automatic cleaning cat litter basin also includes a rake box 7 which is detachably placed on the upper part of the feces dropping port 12. When the moving device 3 drives the cat litter rake 4 to move down and abut against the rake box 7, the cat litter rake 4 can be driven to overcome the torsional force of the torsional spring 42 and rotate to gradually flatten, and finally achieve the storage of the cat litter rake 4 in the rake box 7.

[0073] The automatic cleaning cat litter basin also includes a rake box 7 which is detachably placed on the upper part of the feces dropping port 12. When the moving device 3 drives the cat litter rake 4 to move down and abut against the rake box 7, the cat litter rake 4 can be driven to overcome the torsional force of the torsional spring 42 and rotate to gradually flatten, and finally achieve the storage of the cat litter rake 4 in the rake box 7.

[0074] Thus, by storing the cat litter rake 4, not only is it visually more beautiful, but it also does not occupy the space of the basin 2, and thus does not affect the activity area of the pet cat in the basin 2, and there is no risk of scratching the pet cat, which is safe and reliable.

[0075] Referring to Figure 9 In addition, the utility model also provides a cat litter cleaning method applied to the above automatic cleaning cat litter basin, which comprises the following steps:

[0076] Step one: in the initial state, the cat litter rake 4 is stored in the rake box 7 and the flip cover 5 is placed on the rake box 7 to shield the cat litter rake 4, as shown in Figure 9 (f); when it is necessary to clean the cat litter, the moving device 3 first drives the cat litter rake 4 to move up, and synchronously abuts against the flip cover 5 to drive the flip cover 5 to flip, at which time the cat litter rake 4 is separated from the rake box 7 and elastically resets under the torsional force of the torsional spring 42, as shown in Figure 9 (a);

[0077] Step two: then the moving device 3 drives the cat litter rake 4 to move backward along the length direction of the frame 1 to the end of the basin 2 away from the feces dropping port 12, as shown in Figure 9(b) shown; then the moving device 3 drives the cat litter rake 4 to move obliquely downward and rotate synchronously so that the cat litter rake 4 is located in the basin 2, as shown in Figure 9 (c) shown;

[0078] Step three: then the moving device 3 drives the cat litter rake 4 to move along the length direction of the basin 2 to the other end close to the feces dropping port 12 to rake out the feces from the cat litter, as shown in Figure 9 (d) shown; then the moving device 3 drives the cat litter rake 4 to move obliquely upward and rotate synchronously to push the feces into the feces dropping port 12, thereby completing the cleaning of the cat litter, at this time, the cat litter rake 4 synchronously drives the flap 5 to turn and open, as shown in Figure 9 (e) shown;

[0079] Step four: finally, the moving device 3 drives the cat litter rake 4 to move downward and be accommodated into the rake box 7, at the same time, the flap 5 turns and resets and covers on the rake box 7 to shield the cat litter rake 4, thereby completing the cleaning work, as shown in Figure 9 (f) shown.

[0080] In summary, the automatic cleaning cat litter basin and the cat litter cleaning method have the following beneficial effects:

[0081] (1) The automatic cleaning cat litter basin, the moving device 3 can not only drive the cat litter rake 4 to move along the length direction of the frame 1, but also drive the cat litter rake 4 to move up and down; therefore, after driving the cat litter rake 4 to run from one end of the cat litter containing space 11 to the other end to rake out the feces from the cat litter, the cat litter rake 4 can be driven by the moving device 3 to move upward to push the feces into the feces dropping port 12, thereby not needing to return to the initial position of the cat litter basin and rotate the cat litter rake 4 to a large angle to make the feces drop, like the traditional cat litter rake 4. Therefore, the automatic cleaning cat litter basin can utilize the up-and-down track to push the feces into the feces dropping port 12, thereby not needing to additionally set a rotating mechanism, not only the structure is simple, but also the cleaning track of the cat litter is relatively simple, and the control requirement of the system is relatively low.

[0082] (2) The automatic cleaning cat litter basin, the moving device 3 further has a transmission assembly which is in transmission cooperation with the cat litter rake 4, when the cat litter rake 4 is driven to move upward to push the feces into the feces dropping port 12, the cat litter rake 4 can be synchronously driven to rotate, thereby more conveniently pushing the feces into the feces dropping port 12; in addition, when the cat litter rake 4 has feces adhered thereon, the cat litter rake 4 can also be driven to move up and down and rotate to shake off the feces; furthermore, when the cat litter basin has cat litter accumulated thereon, the up-and-down and rotating track can also be utilized to smooth the cat litter.
