Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, specifically to a pet water fountain with automatic water changing capability. Background Technology

[0002] Pet owners typically use bowls or basins to give their pets water, but these containers are often knocked over by pets, which is not only unhygienic but also a hassle to clean up. Furthermore, pet owners sometimes forget to give their pets water, leaving them without adequate hydration. To address this, pet water fountains have emerged on the market, which can largely solve the pet water problem.

[0003] Most pet water fountains on the market are circulating water fountains, which typically include a water tank, a water pump, a drinking tray, and a filter. The pump draws water from the tank into the drinking tray, and once the water level in the tray reaches the mark, it is filtered and then flows back into the tank, thus creating an automatic cycle. While circulating water fountains allow pets to drink water automatically, some water always remains in the drinking tray, which is easily contaminated and can affect the pet's health. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pet water fountain that can automatically supply water and automatically change the water.

[0005] The technical solution of this utility model is to provide a pet water fountain with automatic water changing function, having the following structure:

[0006] The device includes a clean water tank, a wastewater tank located on one side of the clean water tank, and a drinking water tray located on top of the wastewater tank. The clean water tank is equipped with a water supply component for drawing water from the clean water tank and delivering it to the drinking water tray. The inner bottom wall of the drinking water tray has a drain outlet that communicates with the wastewater tank, and a vertically upward-extending drain pipe is connected to the drain outlet. A siphon assembly is connected to the drinking water tray, which covers the drain pipe and forms a siphon channel connecting the drinking water tray and the wastewater tank.

[0007] With the above structure, the pet water fountain with automatic water changing of this utility model has the following advantages compared with the prior art:

[0008] Water is drawn from the clean water tank by the water supply component and delivered to the drinking dish for the pet to drink. While the pet is drinking, the water supply component controls the water level in the drinking dish to prevent it from exceeding the top of the drain pipe. When water needs to be drained from the drinking dish, the water supply component fills the drinking dish with water, raising the water level above the top of the drain pipe. This creates a siphon effect, causing the water in the drinking dish to drain into the waste tank along the siphon channel, achieving automatic water replacement and keeping the water in the drinking dish clean.

[0009] Preferably, the siphon assembly includes a cover with a concave cavity at the bottom, within which a vertically downward-extending sleeve is provided, with a gap between the lower end of the sleeve and the inner bottom wall of the drinking tray. The sleeve covers the drain pipe, with its inner wall fitting into the outer peripheral wall and top of the drain pipe to form the siphon channel. The lower end of the cover abuts against the inner bottom wall of the drinking tray, and a notch is provided at the lower end of the cover to connect the drinking tray to the siphon channel. When the water level in the drinking tray is higher than the top of the drain pipe, under the siphon effect, the water in the drinking tray enters the siphon channel between the sleeve and the drain pipe through the notch, and then enters the wastewater tank through the opening at the top of the drain pipe, thus automatically emptying the drinking tray.

[0010] Preferably, the water supply assembly includes a water pump, a sensor, and a controller; the bottom of the purified water tank is provided with a water inlet, and the purified water tank is provided with a water outlet above the drinking tray; the two ends of the water pump are connected to the water inlet and the water outlet respectively through pipelines; the sensor is installed on the side wall of the purified water tank near the drinking tray to detect the liquid level in the drinking tray; the controller is electrically connected to the water pump and the sensor respectively to receive the signals transmitted by the sensor and control the switching of the water pump according to the received signals.

[0011] The sensor can monitor the water level in the water dish in real time. When the water level is below a preset range, the controller controls the water pump to fill the dish. When the water level is above the preset range, the water pump stops working to prevent the water level in the dish from exceeding the height of the drain pipe. When the preset emptying time is reached, the controller controls the water pump to continue filling the dish until the water level in the dish exceeds the height of the drain pipe. At this point, due to the siphon effect, the water in the dish will be drained into the wastewater tank along the siphon channel, thus automatically emptying the water dish. After emptying, the controller controls the water pump to fill the dish again for the pet to drink.

[0012] Preferably, the top of the water tank is equipped with a control panel, which is electrically connected to the controller for setting water exchange parameters. The control panel allows users to set the time interval for emptying the drinking tray according to specific needs, enabling automatic drainage on schedule without manual operation, simplifying the process.

[0013] Preferably, the top of the cover has a recessed buffer zone directly below the water outlet. The end of the buffer zone facing the drinking tray is open, and the buffer zone is angled downwards from the end closest to the water tank to the other end. The buffer zone can reduce the impact of water filling and prevent the injected water from splashing out; setting the buffer zone to be angled downwards can prevent water from accumulating in the buffer zone.

[0014] Preferably, the top of the buffer zone is provided with an arc-shaped barrier to prevent water from splashing out when the outlet is filled. Attached Figure Description

At the same time, the terms "first", "second", etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown; This utility model discloses a pet water fountain with automatic water changing: including a clean water tank 1, a wastewater tank 2 set on one side of the clean water tank 1 and a drinking tray 3 set on top of the wastewater tank 2. The clean water tank 1 is equipped with a water purification filter and a water supply assembly. The water purification filter is used to purify the raw water, and the water supply assembly is used to draw the purified water in the clean water tank 1 and deliver it to the drinking tray 3.

[0024] The inner bottom wall of the drinking tray 3 is provided with a sunken area, and a drain outlet 31 connected to the sewage tank 2 is provided in the sunken area. A drain pipe 32 extending vertically upward is connected to the drain outlet 31 (the lower end of the drain pipe 32 extends into the sewage tank 2). A siphon assembly 4 is connected to the drinking tray 3. The siphon assembly 4 covers the drain pipe 32 and forms a siphon channel connecting the drinking tray 3 and the sewage tank 2 between the siphon assembly 4 and the drain pipe 32.

[0025] The siphon assembly 4 includes a cover 41 with a concave cavity at the bottom. A sleeve 42 extending vertically downward is provided in the concave cavity of the cover 41, and the lower end of the sleeve 42 is spaced apart from the inner bottom wall of the drinking tray 3. The sleeve 42 covers the drain pipe 32, and the inner wall of the sleeve 42 is spaced apart from the outer peripheral wall and top of the drain pipe 32 to form the aforementioned siphon channel. The lower end of the cover 41 abuts against the inner bottom wall of the drinking tray 3, and the lower end of the cover 41 is provided with a notch 411 for connecting the drinking tray 3 with the siphon channel.

[0026] When the water level in the drinking tray 3 is higher than the top of the drain pipe 32, the water in the drinking tray 3 will enter the siphon channel between the sleeve 42 and the drain pipe 32 through the gap 411 under the siphon effect, and then enter the sewage tank 2 through the opening at the top of the drain pipe 32, thus realizing the automatic emptying of the drinking tray 3.

[0027] The water supply assembly includes a water pump 11, a sensor 12 (e.g., a liquid level sensor), and a controller 13. The bottom of the purified water tank 1 is provided with a water inlet 14, and the purified water tank 1 is provided with a water outlet 15 above the drinking tray 3. The two ends of the water pump 11 are connected to the water inlet 14 and the water outlet 15 respectively through pipelines. The sensor 12 is set on the side wall of the purified water tank 1 near the drinking tray 3 and is used to detect the liquid level in the drinking tray 3. The controller 13 is electrically connected to the water pump 11 and the sensor 12 respectively and is used to receive the signal transmitted by the sensor 12 and control the switch of the water pump 11 according to the received signal.

[0028] Sensor 12 can monitor the water level in the water dish 3 in real time. When the water level is below the preset range, controller 13 controls water pump 11 to add water. When the water level is above the preset range, water pump 11 stops working to prevent the water level in the water dish 3 from exceeding the height of the top of the drain pipe 32. When the preset emptying time is reached, controller 13 controls water pump 11 to continue adding water until the water level in the water dish 3 exceeds the height of the top of the drain pipe 32. At this time, under the siphon effect, the water in the water dish 3 will be discharged into the wastewater tank 2 along the siphon channel, realizing automatic emptying of the water dish 3. After emptying, controller 13 controls water pump 11 to add water again for the pet to drink.

[0029] The top of the water tank 1 is equipped with a control panel 16, which is electrically connected to the controller 13. The time interval for emptying the drinking water tray 3 can be set according to specific needs, so that it can automatically drain the sewage on time without manual operation, which is simple and convenient.

[0030] This invention uses a water pump 11 to draw water from the water tank 1 and deliver it to the drinking tray 3 for pets to drink.

[0031] Sensor 12 will constantly detect the liquid level in the water bowl 3 and control it within a preset range (the preset liquid level is lower than the height of the top of the drain pipe). When the liquid level drops due to the pet drinking water, the controller 13 controls the water pump 11 to inject water according to the signal transmitted by the sensor 12, so that the water in the water bowl 3 is kept at the preset liquid level. When it is time to change the water, the sensor 12 controls the water pump 11 to continue injecting water until the liquid level in the water bowl 3 is higher than the height of the top of the drain pipe 32 and then stops. At this time, under the siphon effect, the water in the water bowl 3 will be discharged into the sewage tank 2 along the siphon channel. After the water in the water bowl 3 is emptied, the controller 13 controls the water pump 11 to inject water again for the pet to drink, thereby achieving the purpose of automatic water changing and keeping the water in the water bowl (3) clean.

[0032] The top of the cover 41, directly below the water outlet 15, has a recessed buffer zone 412 to reduce the impact of water filling and prevent splashing. The end of the buffer zone 412 facing the drinking tray 3 is open, and the buffer zone 412 is angled downwards from the end closest to the water tank 1 to the other end to prevent water accumulation. The top of the buffer zone 412 has an arc-shaped baffle 413 to further prevent water from splashing out of the water outlet 15.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
