[0029] 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.
[0030] Please refer to the following: Figures 1 to 4 This utility model embodiment provides a pet litter box with plasma purification function, mainly including a litter box 1, a main unit 2, a waste collection box 3, a plasma generator 7 and a fan 8. The litter box 1 is located on the top of the main unit 2, and the waste collection box 3 is located at the bottom of the main unit 2. The main unit 2 is connected to the litter box 1 and is used to drive the litter box 1 to rotate. The litter box 1 is provided with an outwardly open litter trough 111 for collecting litter. The waste collection box 3 is used to collect litter clumps falling downward from the litter box 1. Taking cat use as an example, after the cat finishes urinating or defecating in litter box 1, the feces and urine mix with the litter to form litter clumps. After the cat leaves, the main unit 2 drives litter box 1 to rotate. During the rotation, the internal filter 123 of litter box 1 rotates with the litter clumps, while other cat litter that has not clumped is not carried away by the filter 123 and remains at the bottom of litter box 1 due to its own gravity. When litter box 1 rotates to a designated angle, the litter clumps will slide down the surface of the guide plate 122 inside litter box 1 due to their own weight and fall into the waste collection bin 3 below. Then, the main unit 2 drives litter box 1 to return to its initial position, completing the automatic cleaning function for cat feces and urine. The plasma generator 7 and fan 8 mentioned above are both fixed on the main unit 2 and electrically connected to the main unit 2. The main unit 2 distributes the required electrical energy to the plasma generator 7 and fan 8 respectively. The plasma generator 7 is existing technology, which generates plasma (positive and negative ion clusters) through high-voltage discharge. These plasmas are used to destroy the molecular structure of pollutants, thereby purifying the gas. The outer wall of the sand chamber 1 has through holes 119 that extend into the sand trough 111 at the positions corresponding to the plasma generator 7 and the fan 8.
[0031] Specifically, this solution is based on the structural design of the sand chamber 1, which, driven by the main unit 2, pours sand containing urine and feces into the feces collection chamber 3 by rotating. A plasma generator 7 and a fan 8, powered by the main unit 2, are installed on the main unit 2. A through hole 119 is provided on the outer wall of the sand chamber 1, which leads to the sand trough 111. This allows the fan 8 to blow the ionized substances from the plasma generator 7 through the through hole 119 into the sand trough 111 of the sand chamber 1, thereby purifying the air in the sand trough 111. This improves the freshness of the surrounding air and optimizes the user experience.
[0032] Please refer to the following: Figures 1 to 5 The sand chamber 1 has a rotating shaft 118 protruding on both opposite sides, and the main unit 2 has a rotating hole 2113 on both opposite sides. The two rotating shafts 118 are installed one-to-one with the two rotating holes 2113. The aforementioned through hole 119 is provided on the outer wall of the rotating shaft 118 and passes through the rotating shaft 118. The aforementioned plasma generator 7 and fan 8 are both arranged in adjacent positions on the rotating shaft 118 with the through hole 119. Through the above design, the sand chamber 1 can reliably rotate relative to the main unit 2, and the fan 8 will not hinder the sand tank 111 from blowing ionized substances into the sand trough 111 when the sand chamber 1 rotates to any position. That is, during the automatic cleaning of urine and feces, the air in the sand trough 111 can be continuously purified, which is conducive to further improving the freshness of the surrounding air.
[0033] Please refer to the following: Figure 2 and Figure 5 The sand hopper 1 has a gear 114 on one of the rotating shafts 118. The main unit 2 includes a drive gear 22 that meshes with the gear 114. When the drive gear 22 rotates, it can drive the entire sand hopper 1 to rotate. The top of the main unit 2 is provided with a freely rotating roller 23. Multiple rollers 23 together support the sand hopper 1. During the rotation of the sand hopper 1, it will drive the rollers 23 below to rotate, so as to solve the problem of large friction between the sand hopper 1 and the main unit 2 during rotation.
[0034] Please refer to the following: Figures 2 to 6The main unit 2 has an upwardly protruding protrusion 2117 on the outside of one of the rotating holes 2113. The side of the protrusion 2117 facing the sand chamber 1 has a receiving groove 2118. The plasma generator 7 and the fan 8 are both housed in this receiving groove 2118. The main unit 2 includes a cover plate 20 for covering the opening of the receiving groove 2118. The plasma generator 7 is exposed outward relative to the cover plate 20. With this design, the plasma generator 7 and the fan 8 can be hidden inside the main unit 2, which improves the appearance and helps to extend the service life of the plasma generator 7 and the fan 8. Based on the above design, the cover plate 20 has a through-hole 201 at the position corresponding to the fan 8. The through-hole 201 communicates with the aforementioned through hole 119. The outer wall of the protrusion 2117 has an air inlet 2119 that communicates with the receiving groove 2118. The air inlet 2119 is located on the side of the protrusion 2117 facing away from the cover plate 20. By setting the air inlet 2119 and the air outlet 201, it is ensured that the fan 8 can blow the material ionized by the plasma generator 7 into the sand tank 111. In addition, a cable channel 2110 is opened at the bottom of the receiving groove 2118, which communicates downward to the inside of the host 2. By setting this cable channel 2110, the cables on the plasma generator 7 and the fan 8 can pass through the cable channel 2110 and establish an electrical connection with the host 2, so that the host 2 can provide the required power to the plasma generator 7 and the fan 8 respectively.
[0035] Please refer to the following: Figure 1 , Figure 2 , Figure 5 and Figure 6The pet litter box also includes two handle covers 6 that are snapped together with the main unit 2. Each rotating hole 2113 has an upward-opening mounting and disassembly opening 2114 above it. Two rotating shafts 118 are inserted into the corresponding rotating hole 2113 through the corresponding mounting and disassembly opening 2114. One handle cover 6 covers one of the rotating shafts 118 of the litter box 1 at one of the mounting and disassembly openings 2114, and the other handle cover 6 covers the other rotating shaft 118 of the litter box 1 at the other mounting and disassembly opening 2114. The main unit 2 has a socket 2115 below each handle cover 6. The socket 2115 is preferably located on the side of the protrusion 2117 facing away from the litter box 1. When the handle cover 6 is inserted downward into the socket 2115, the handle cover 6 is in a locked state that cannot be removed from the main unit 2. When the handle cover 6 is disengaged upward from the socket 2115, the handle cover 6 is in an unlocked state that can be removed from the main unit 2. By providing the installation and removal opening 2114, the litter box 1 is detachable from the main unit 2, facilitating the installation, disassembly, and cleaning of the entire litter box 1. The handle cover 6 prevents the pet from being caught in the rotating shaft 118 of the litter box 1 during rotation, improving the pet's safety when using the litter box. In addition to covering the rotating shaft 118 of the litter box 1, the handle cover 6 also features an outer handle 62, allowing the user to easily lift the entire litter box and move it to a desired location.
[0036] Please refer to the following: Figures 2 to 4 The accommodating slot 2118 is also equipped with a sensor 9, which is also powered by the host 2. The sensor 9 protrudes outward relative to the cover plate 20 mentioned above. The sensor 9 is used to detect the sand volume in the sand chamber 1 and to remind the user in time to add sand to the sand trough 111, thereby further improving the user experience. This sensor 9 is preferably a TOF sensor. A TOF (Time of Flight) sensor is a 3D sensor that calculates distance by measuring the time difference between the emission and reflection of light or signal.
[0037] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
