DETAILED DESCRIPTION
[0020] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.
[0021] like Figure 1 and 2 As shown, this embodiment provides an automatic sand replenishing and water flushing cat litter box, including a box body 1, a sand storage box 2, a guide plate 4, a crusher 5, a water inlet pipe 6, a water outlet pipe 7 and a sensor 8.
[0022] The top of the box body 1 is provided with an opening 11, and the front side is provided with a notch 12, which is connected with the opening 11. The cat can enter and exit the box body 1 from the notch 12, and can also enter and exit the box body 1 from the opening 11; according to the nature of cats, the notch 12 is generally used as an entrance and exit, so the size of the entrance and exit should be appropriate, and cats of various sizes can enter from it as much as possible. The sand storage box 2 is arranged horizontally in the box body 1, and the internal space of the box body 1 is divided into an upper space and a lower space by the sand storage box 2, and the lower space is the defecation space of the cat. A certain distance is left between the rear part of the sand storage box 2 and the rear wall plate of the box body 1 to form an entrance and exit channel 3 connecting the upper and lower spaces, and the cat enters the lower space from the upper space or returns to the upper space from the lower space. The sand storage box 2 is used to store dry cat litter (because the cat litter box of the present application adopts a flushing design, so tofu litter is preferably stored in the sand storage box 2). The bottom of the sand storage box 2 is provided with a sand outlet 21, and an electrically controlled sand outlet valve 22 is provided at the sand outlet 21 to control the timing and amount of sand replenishment. The guide plate 4 is used as the bottom plate of the lower space and is tilted in the lower space. The tilt angle is between 5-20°. In this scheme, the tilt angle is 10°. The rear end of the guide plate 4 is higher than the front end so that all cat feces can be flushed away when flushing. The guide plate 4 is similar in shape to the inner wall of the flush toilet, and can collect water to the position connected to the material inlet of the crusher when flushing, but the inclination angle of the guide plate 4 is smaller. The crusher 5 is arranged in the lower space. The crusher 5 is detachably arranged at the bottom of the guide plate 4, which is convenient for replacing and cleaning the crusher 5; its material inlet is connected to the front end of the guide plate 4, so as to ensure that cat litter and feces can enter the crusher 5 with water when flushing. One end of the water inlet pipe 6 extends into the lower space and is above the rear end of the guide plate 4, and the other end is connected to the tap water pipe outside the box body 1; an electric-controlled water inlet valve 61 is provided on the water inlet pipe 6 to control the flushing time. One end of the water outlet pipe 7 is connected to the material outlet of the crusher 5, and the other end extends out of the box body 1 (generally into the sewer pipe) so that the feces and used cat litter can be flushed away by flushing. The sensor 8 is arranged in the upper space or the lower space of the box body 1 and is electrically connected to the electric-controlled sand outlet valve 22, the electric-controlled water inlet valve 61 and the crusher 5, and is used to control the operation of the electric-controlled sand outlet valve 22, the electric-controlled water inlet valve 61 and the crusher 5.
[0023] After the cat has defecated, it leaves the box body 1. The sensor 8 senses that the cat has left, and the electrically controlled water inlet valve 61 is opened for flushing. The water flow flushes the feces and cat litter into the grinder 5. The grinder 5 is started to crush (break up) the feces and cat litter to avoid clogging the sewer. The crushed feces and cat litter are discharged into the sewer from the outlet pipe. Then the grinder stops working and the electrically controlled water inlet valve 61 is closed. The electrically controlled sand outlet valve 22 is opened to discharge a proper amount of dry cat litter in the sand storage box 2 onto the guide plate 4 to lure the cat to defecate here. Then the electrically controlled sand outlet valve 22 is closed. In this way, the feces can be automatically cleaned and the cat litter box can be kept clean. Manual intervention is greatly reduced, freeing pet owners from the frequent cleaning of cat litter. The automated cleaning process ensures the sanitary conditions of the cat litter box, while also avoiding the environmental pollution that may be caused by traditional cat litter processing.
[0024] The sensor 8 may be an infrared sensor. By way of example, the guide plate 4 may also be referred to as a guide slope, a slideway, a chute, etc. By way of example, the pulverizer 5 may also be referred to as a blender, a crusher, etc.
[0025] Exemplarily, the sensor 8 is connected to a circuit board 81, and the circuit board 81 is electrically connected to the electric-controlled sand outlet valve 22, the electric-controlled water inlet valve 61 and the crusher 5. The sensor 8 serves as a signal input end, and provides an electrical signal to the circuit board 81 when the cat leaves. After receiving the electrical signal, the circuit board 81 controls the electric-controlled water inlet valve 61, the crusher 5 and the electric-controlled sand outlet valve 22 to operate in turn.
[0026] In one embodiment, the automatic sand replenishing and water flushing cat litter box further includes a dryer 9, which is arranged on the outside of the bottom of the sand storage box 2, and the dryer 9 is electrically connected to the sensor 8. Exemplarily, the dryer 9 is electrically connected to the circuit board 81, and is indirectly controlled by the electrical signal of the sensor 8 and directly controlled by the circuit board 81. When the flushing, crushing, and sewage discharge (referring to the process of discharging the crushed cat litter feces) are completed, the dryer 9 is turned on to dry the water remaining on the surface of the guide plate 4. After the drying is completed, the dryer 9 stops working, and the electrically controlled sand outlet valve 22 is opened to replenish the sand.
[0027] In one embodiment, the top of the sand storage box 2 is provided with a sand loading port, and an openable and closable box cover 23 is installed at the sand loading port. After opening the box cover 23, cat litter is loaded into the sand storage box 2 to ensure that the cat litter is sufficient.
[0028] In one embodiment, the box cover 23 is provided with evenly distributed sand leakage holes. In this way, the possibility of cats carrying cat litter out of the cat litter box can be reduced.
[0029] In one embodiment, the bottom of the sand storage box 2 is tilted, and the sand outlet 21 is arranged at a low position of the bottom of the box. In this way, it is more conducive to the unloading of cat litter.
