DETAILED DESCRIPTION

[0022] In order to make the technical solution and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The utility model provides a technical solution: Figure 1-6 The utility model discloses a tofu cat litter water adding and spraying device, comprising a water pump 1, a water storage cylinder 2 and a guide plate 3. The water storage cylinder 2 is provided with a water supply component 4, and the water supply component 4 includes a drainage mechanism 41. The drainage mechanism 41 is arranged at the center position in the water storage cylinder 2. A water inlet mechanism 42 is arranged on the outer peripheral side of the drainage mechanism 41. The water inlet of the guide plate 3 is connected with the drainage end of the water pump 1 through a connecting pipe, and a spraying mechanism 5 is arranged on the bottom side of the guide plate 3.

[0024] In this embodiment, when the improved tofu cat litter water spraying device is used, the external water source injects water into the water storage cylinder 2 through the water inlet mechanism 42, and as the water level in the water storage cylinder 2 rises, the drainage mechanism 41 moves up synchronously. After a specific amount of water is stored in the water storage cylinder 2, the water inlet mechanism 42 automatically disconnects the water storage cylinder 2 from the external water source, and then the operator adjusts the maximum downward movement length of the drainage mechanism 41 according to the amount of raw materials to be mixed as needed, and then the water pump 1 starts to pump out the water in the water storage cylinder 2 at a uniform speed. As the water in the water storage cylinder 2 is lost, the water level in the water storage cylinder 2 drops accordingly, and the drainage mechanism 41 moves downward at the same time, until the drainage mechanism 41 moves down to the maximum length, and the water is separated from the drainage mechanism 41, so that the water pump 1 will no longer pump water from the water storage cylinder 2, and the water pump 1 will only pump out a set amount of water from the water storage cylinder 2 and inject the water into the diverter plate, and the water injected into the diverter plate can be sprayed on the raw materials in the tofu cat litter raw material mixing device more evenly through the spraying mechanism 5;

[0025] It should be noted that the above-mentioned guide plate 3 is fixedly installed above the feed port of the tofu cat litter mixing device, and the bottom side of the guide plate 3 is gap-matched with the feed end of the tofu cat litter mixing device; the shape of the above-mentioned guide plate 3 can be adaptively changed according to the shape of the plate bin of the tofu cat litter mixing device.

[0026] In a further preferred embodiment of the present invention, Figure 2 As shown, the drainage mechanism 41 includes a drainage pipe 411, which is slidably installed at the center of the top side of the water storage cylinder 2, and a floating plate 412 is fixedly sleeved on the bottom end of the drainage pipe 411. The top end of the drainage pipe 411 is connected to the water inlet end of the water pump 1 through a water pipe.

[0027] In the present embodiment, as the water in the water storage cylinder 2 flows in or out, the water level in the water storage cylinder 2 rises or falls. At this time, due to the push of the buoyancy of the float 412 on the drain pipe 411 and the effect of the gravity of the drain pipe 411 itself, the drain pipe 411 moves up or down accordingly. As a result, during the change of the water level in the water storage cylinder 2, the bottom end opening of the drain pipe 411 is always in contact with the water surface and will not affect the water suction operation of the water pump 1.

[0028] In a further preferred embodiment of the present invention, Figure 2 and Figure 3As shown, a limiting ring 413 is provided on the sliding sleeve of the outer peripheral side of the drain pipe 411, and a plurality of rectangular grooves 414 are sequentially provided on the outer peripheral wall of the drain pipe 411 from top to bottom, and the spacing between two adjacent rectangular grooves 414 is equal, and a sliding groove 415 is provided on the inner ring wall of the limiting ring 413, and a rectangular block 416 is slidably installed in the sliding groove 415, and the corner of one end of the rectangular block 416 is arranged in an arc shape and inserted into the corresponding rectangular groove 414, and a handle 417 is provided on the outer peripheral side of the limiting ring 413, and the connecting end of the handle 417 is inserted into the sliding groove 415 and fixedly connected to the other end of the rectangular block 416, and a spring 418 is provided between the rectangular block 416 and the inner wall of the sliding groove 415, and the two ends of the spring 418 are respectively fixedly connected to the inner wall of the rectangular block 416 and the sliding groove 415;

[0029] In this embodiment, when adjusting the maximum downward length of the drain pipe 411, the operator pulls the rectangular block 416 out of the rectangular groove 414 through the handle 417 and pushes the limiting ring 413 so that the limiting ring 413 slides along the drain pipe 411. The limiting ring 413 is adjusted to a suitable position according to the amount of tofu cat litter mixed with the tofu cat litter. Then, the operator releases the handle 417. At this time, due to the push of the spring 418 on the rectangular block 416, the rectangular block 416 is automatically inserted into the corresponding rectangular groove 414. At this time, due to the mutual interference between the rectangular block 416 and the inner wall of the rectangular groove 414, the position between the limiting ring 413 and the drain pipe 411 is locked.

[0030] As the drain pipe 411 moves downward, the distance between the limit ring 413 and the water cylinder 2 gradually decreases. After the limit ring 413 contacts the water cylinder 2, the drain pipe 411 cannot move further downward due to the mutual interference between the limit ring 413 and the water cylinder 2. The bottom opening of the drain pipe 411 is automatically separated from the water surface, and the water pump 1 will not continue to absorb the water in the water cylinder 2. The device has a high degree of automation and does not require the operator to perform other operations.

[0031] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the water inlet mechanism 42 includes an electrically controlled valve 421, which is arranged on the outer peripheral side of the limiting ring 413, and the drainage end of the electrically controlled valve 421 is fixedly penetrated through the wall of the water storage cylinder 2, and a support rod 422 in a U-shape is fixedly installed on the top of the water storage cylinder 2, and both ends of the support rod 422 are located on the outer peripheral side of the electrically controlled valve 421 and the drainage pipe 411, and a sensor 423 is provided at the middle position of the inner top side of the support rod 422, and the top of the pressure sensor 423 is inserted into the support rod 422 and is threadedly connected to the support rod;

[0032] In this embodiment, as the water level in the water storage cylinder 2 rises, the drain pipe 411 moves upward accordingly. When the top side of the drain pipe 411 collides with the pressure sensor 423, the pressure sensor 423 detects the thrust from the drain pipe 411, and the control panel controls the electric control valve 421 to close, so that a specific amount of water is stored in the storage cylinder. The device has a high degree of automation and does not require the operator to perform other operations.

[0033] It should be noted that a control panel is fixedly installed at the front end of the top side of the above-mentioned fixed cylinder to control the operating status of the electric control valve 421 and the water pump 1; the water inlet end of the above-mentioned electric control valve 421 is connected to the external water source, namely the faucet.

[0034] In a further preferred embodiment of the present invention, Figure 1 and Figure 5 As shown, the spraying mechanism 5 includes a plurality of pressure limiting valves 51, which are arranged in a circular pattern on the bottom side of the guide plate 3, and the water inlet end of each pressure limiting valve 51 is fixedly passed through the plate wall of the guide plate 3, and the distance between two adjacent pressure limiting valves 51 is equal;

[0035] In this embodiment, the water pump 1 injects water into the guide plate 3 through the connecting pipe while pumping out the water in the water storage cylinder 2, thereby generating a pressure difference at both ends of the pressure limiting valve 51. The excess water in the guide plate 3 is evenly diverted through a plurality of pressure limiting valves 51 and discharged from the guide plate 3 at the pressure limiting valves 51, thereby diverting the water pumped out of the water storage cylinder 2 and expanding the water spraying area.

[0036] In a further preferred embodiment of the present invention, Figure 5 and Figure 6 As shown, a spherical block 52 is provided at the center position below the pressure limiting valve 51, and the spherical block 52 is fixedly connected to the guide plate 3 through a connecting rod;

[0037] In this embodiment, the water droplets discharged from the pressure limiting valve 51 impact on the spherical block 52. Due to the obstruction of the spherical block 52, the water flow is further diverted and slightly scattered around, thereby further expanding the spraying area. Finally, due to the effect of the water's own gravity, the water discharged from the guide plate 3 automatically falls on the raw materials of the tofu cat litter mixing device. The tofu cat litter mixing device mixes the raw materials, thereby spraying the water on as many raw materials as possible.

[0038] Working principle: When the improved tofu cat litter water-adding spraying device is used, the operator first uses a conduit to connect the electric control valve 421 to the faucet of the external water source, and then the operator controls the control panel to start the electric control valve 421, and the external water flows into the water storage cylinder 2 from the electric control valve 421, and the water pump 1 is started synchronously to extract a specific amount of water from the water storage cylinder 2 through the drainage pipe 411, and inject the water into the guide shell, so that the guide shell and the connecting pipe are filled with water;

[0039] As the amount of water in the water storage cylinder 2 increases, the water level in the water storage cylinder 2 rises accordingly, and the floating plate 412 pushes the drain pipe 411 upward, so that the drain pipe 411 rises together with the water level until the top of the drain pipe 411 conflicts with the pressure sensor 423. At this time, the pressure sensor 423 detects the thrust from the drain pipe 411, and the control panel controls the electric control valve 421 to close. At this time, a specific amount of water is stored in the storage cylinder, and then the operator pulls the rectangular block 416 out of the rectangular groove 414 through the handle 417, and pushes the limit ring 413, so that the limit ring 413 slides along the drain pipe 411, and adjusts the limit ring 413 to a suitable position according to the amount of tofu cat litter mixed, and then the operator releases the handle 417. At this time, due to the push of the spring 418 on the rectangular block 416, the rectangular block 416 is automatically inserted into the corresponding rectangular groove 414. At this time, due to the mutual conflict between the rectangular block 416 and the inner wall of the rectangular groove 414, the position between the limit ring 413 and the drain pipe 411 is locked;

[0040] After the adjustment of the above device is completed, the operator controls the water pump 1 to run through the control panel. The water pump 1 draws out the water in the water storage cylinder 2 at a uniform speed through the drain pipe 411 and the water pipe, and injects the water into the guide plate 3 through the connecting pipe. At this time, a pressure difference is generated at both ends of the pressure limiting valve 51. The excess water in the guide plate 3 is evenly diverted through a plurality of pressure limiting valves 51 and discharged from the guide plate 3 from the pressure limiting valves 51. The water droplets discharged from the pressure limiting valves 51 impact on the spherical blocks 52. Due to the obstruction of the spherical blocks 52, the water flow is further diverted to the surroundings and slightly scattered, thereby further expanding the spraying area. Finally, due to the effect of the water's own gravity, the water discharged from the guide plate 3 automatically falls on the raw materials of the tofu cat litter mixing device, and the tofu cat litter mixing device performs a mixing process on the raw materials.

[0041] As the water in the water storage cylinder 2 flows out, the water level in the water storage cylinder 2 drops accordingly, and due to the gravity of the drain pipe 411 and the floating plate 412, the drain pipe 411 drops synchronously with the water level, so that the bottom opening of the drain pipe 411 is always in contact with the water surface in the water storage cylinder 2, until the limit ring 413 and the water storage cylinder 2 collide with each other, the drain pipe 411 cannot continue to drop, and the bottom opening of the drain pipe 411 is separated from the water surface in the water storage cylinder 2, the water pump 1 will not continue to pump out the water in the water storage cylinder 2, and the control panel automatically controls the water pump 1 to stop running when the water pump 1 is idling, and the spraying operation of the raw materials in the tofu cat litter mixing device is completed;

[0042] When the water pump 1 stops running, the control panel controls the electric control valve 421 to open, so that water is refilled into the water storage cylinder 2 according to the above, so that a specific amount of water is re-stored in the water storage cylinder 2, and the mixing process of multiple tofu cat litter raw materials can be continuously carried out according to the above repeated operations.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
