Description

Technical Field

[0001] This utility model relates to the technical field of pet products, and more specifically, to a cat litter box with a spring-wire power supply structure. Background Technology

[0002] It's a cat's natural instinct to bury its feces after defecating. Currently, pet owners generally provide their pets with dedicated litter boxes or toilets to guide them to eliminate in a designated area. Most existing cat litter clumps when wet, making it easy to remove from the dry litter without needing to replace all the litter. Litter boxes are categorized into electrically operated and non-electrically operated litter boxes.

[0003] In existing electric litter boxes, the motor assembly often moves along with the cleaning rake. The positional relationship between the motor assembly and the power source changes. When the distance between the motor assembly and the power source is shortest, the required wire length is shortest, and when the distance is longest, the required wire length is longest. The longest wire length must be used to adapt to the positional changes. As a result, during the movement, the wire often bulges out a large section, which can easily lead to problems such as tangling, which adversely affects the movement of the motor assembly. Utility Model Content

[0004] The purpose of this invention is to provide a cat litter box with a spring wire power supply structure, which aims to solve the problem that the wires of the motor assembly of the electric cat litter box are prone to tangling in the prior art.

[0005] This invention is implemented as follows: a litter box with a spring-wire powered structure includes an outer basin, an inner liner, a litter box, a cleaning rake, a drive assembly, and a track. The inner liner is detachably mounted on the outer basin, and the litter box is mounted at the head of the outer basin. The track is located on the side of the outer basin and is horizontally arranged. The drive assembly drives the cleaning rake to reciprocate along the track's extension direction. The drive assembly includes a motor, a drive gear, and a rack. The rack is located on the side of the outer basin and below the track, parallel to the track, with its working surface facing downwards. The drive gear meshes with the rack.

[0021] Reference Figures 1 to 7 The image shown is a preferred embodiment of the present invention.

[0022] A litter box with a spring-loaded power supply includes an outer basin 100, an inner liner 200, a litter box 300, a cleaning rake 400, a drive assembly 500, and a track 600. The inner liner 200 is detachably mounted on the outer basin 100, and the litter box 300 is mounted on the head of the outer basin 100. The track 600 is located on the side of the outer basin 100 and is horizontally arranged. The drive assembly 500 drives the cleaning rake 400 to reciprocate along the extension direction of the track 600.

[0023] The drive assembly 500 includes a motor 501, a drive gear 502, and a rack 503. The rack 503 is located on the side of the outer basin 100 and below the track 600, parallel to the track 600, with its working surface facing downwards. The drive gear 502 meshes with the rack 503. The motor 501 drives the drive gear 502 to rotate, causing the drive gear 502 to reciprocate on the rack 503. The outer basin 100 has a wiring port at its rear end for connecting to an external power source, typically via a power adapter connected to AC power. A spring-wire power supply structure 700 is installed inside the track 600. One end of the spring-wire power supply structure 700 is electrically connected to the wiring port, and the other end is electrically connected to the motor 501.

[0024] The litter box with a spring wire power supply structure provided in this embodiment uses a cleaning rake 400 driven by a motor 501 to automatically clean the litter in the inner liner 200 of the litter box. The wiring port of the outer basin 100 is used to connect to an external power source. The electrical connection between the motor 501 and the wiring port is realized through the spring wire power supply structure 700 located in the track 600. The spring wire power supply structure 700 can be stretched or contracted, which can well adapt to the positional changes between the motor 501 and the wiring port, so that the wire will not bulge out a large section, reducing the occurrence of wire tangling.

[0025] Specifically, the spring wire power supply structure 700 includes a wire that extends in a spiral shape, making the entire wire like a spring, which can be easily stretched or contracted.

[0026] Specifically, the outer basin 100 has a driving member 510 and a driven member 520 on each side, which are connected by a transmission shaft. A motor 501 is located inside the driving member 510, and a driving gear 502 is located at one end of the transmission shaft near the driving member 510. A driven gear is located at the other end of the transmission shaft. When the motor 501 drives the driving gear 502 to rotate, the transmission shaft rotates accordingly, causing the driven gear to rotate. The driving gear 502 and the driven gear are fixedly connected to both ends of the transmission shaft. When the driving gear 502 is driven by the motor 501, the transmission shaft and the driven gear rotate synchronously, thus causing the driving member 510 and the driven gear 520 to move synchronously, resulting in smooth movement of the cleaning rake 400.

[0027] A strip-shaped hole 160 is provided on the lower side wall of the outer basin 100. The drive shaft passes through the strip-shaped hole 160. When the active component drives the cleaning rake to move back and forth, the drive shaft moves back and forth in the strip-shaped hole 160 accordingly.

[0028] Both the driving member 510 and the driven member 520 have guide wheels 610 on their inner sides, which cooperate with the track 600. The guide wheels 610 can usually be rollers. During the movement, the rollers roll along the track 600, reducing friction. In addition, the rack 503 below the track 600 is parallel to the track 600. The cooperation between the guide wheels 610 and the track 600, as well as the cooperation between the driving gear 502 and the rack 503, together ensure the smooth operation of the driving member 510 and the driven member 520.

[0029] The inner sides of the driving member 510 and the driven member 520 are also provided with a limit buckle 620. The limit buckle 620 is located above the guide wheel 610 and is arranged in an L-shape. The upper inner side of the limit buckle 620 abuts against the inner side wall of the upper part of the track 600 to prevent the driving member 510 and the driven member 520 from disengaging from the track 600.

[0030] The active component 510 is equipped with a control circuit board 513. The spring wire power supply structure 700 and the motor 501 are electrically connected to the control circuit board 513, and the control circuit board 513 can be used to easily control the power on / off, automatic cleaning, etc.

[0031] The outer side of the active component 510 is equipped with a control panel, which includes a power button 5141 for turning the device on and off, a start button 5142 for activating the one-button cleaning function, etc., making it convenient for users to operate the litter box.

[0032] Furthermore, the active component 510 includes a swing arm 511, the top of which is connected to one end of the cleaning rake 400. A micro motor 5111 is located at the tail of the swing arm 511. The active component 510 contains an arc-shaped rack and pinion rail 512. The micro motor 5111 is connected to a first gear 5112, which meshes with the rack and pinion rail 512. When the cleaning rake 400 moves from the head to the tail of the inner liner 200, the micro motor 5111 is not in operation. Upon reaching the tail, the micro motor 5111 drives the first gear 5112 to rotate. The first gear 5112 moves on the rack and pinion rail 512, causing the swing arm 511 to swing, thus causing the cleaning rake 400 to rotate. The collecting claw 420 then tilts upwards, scooping cat excrement from the litter into the collecting claw 420.

[0033] Furthermore, the cleaning rake 400 includes a collecting claw 420 and a crossbar 410. The crossbar 410 is located on the upper part of the collecting claw 420. Both ends of the crossbar 410 have bent sections 411. The bent sections 411 near the driving member 510 are inserted into the top of the swing arm 511. In this way, the bent sections 411 will swing synchronously with the swing arm 511, so that the cleaning rake 400 can rotate a certain angle.

[0034] Furthermore, the cleaning rake 400 also includes guide frames 430 located on both sides of the collecting paw 420. The guide frames 430 are arranged protruding relative to the collecting paw 420. The litter box 300 is provided with a litter cover 310, and the bottom ends of the litter cover 310 are provided with guide grooves. When the guide frame 430 abuts against the guide groove, the guide frame 430 pushes open the litter cover 310. After the cleaning rake 400 returns from the tail to the head of the inner liner 200, the swing arm 511 continues to swing at a certain angle, and the guide frame 430 will gradually push up the litter cover 310 to automatically empty the cat excrement on the cleaning rake 400 into the litter box 300. Usually, a litter bag can be placed in the litter box 300. When using a litter box, only the litter bag needs to be changed, and the litter box 300 does not need to be cleaned frequently.

[0035] The bottom of the guide frames 430 on both sides are connected by a transverse rod 431, and the guide frames 430 on both sides and the transverse rod 431 are integrally formed.

[0036] The bottom of the outer basin 100 is equipped with a drawer box 110, which is located below the litter box 300. The drawer box 110 can be used to store items such as garbage bags and tissues, making it convenient to change the garbage bags in the litter box.

[0037] A fence 120 is also provided at the top edge of the outer basin 100 to reduce the probability of cat litter overflowing into the inner liner 200 during the cleaning process of the cleaning rake 400.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
