[0041] Reference Figure 1 As shown, Figure 1A schematic structural diagram of a water tank device provided in an embodiment of the present application. This embodiment discloses a water tank device 100, which includes a box body 1, a cover plate 2 and a float valve 3. The box body 1 is provided with a accommodating chamber 11, and an overflow port 12 is provided on the side of the box body 1. The cover plate 2 is covered on the box body 1, and the cover plate 2 is provided with a water outlet 23 and a return port 21. The water outlet 23 and the return port 21 are respectively connected to the water-using equipment. The float valve 3 includes a connecting rod and a ball. The connecting rod is connected to the cover plate 2, and the connecting rod is provided with a channel, and the accommodating chamber 11 is connected to the outside atmosphere through the channel. The ball is connected to the connecting rod and is located in the accommodating chamber 11, and the vertical distance between the ball and the cover plate 2 is less than the vertical distance between the overflow port 12 and the cover plate 2. When the water level in the accommodating chamber 11 rises above the overflow port 12 and blocks the ball in the channel, the accommodating chamber 11 is isolated from the outside atmosphere. Among them, the height direction of the box body 1 is Figure 1 The X direction in .

[0042] In this embodiment, the water tank device also includes a breathing valve 4, which is arranged on the side of the cover plate 2 facing away from the box body 1 and is connected to the connecting rod, and the breathing valve 4 is connected to the channel. The breathing valve 4 is used to reduce the entry of dust and other impurities into the accommodating chamber 11 when the float valve 3 is connected to the outside atmosphere, and the breathing valve 4 can automatically open and close to ensure that the pressure in the water tank device 100 is maintained within a safe range, thereby achieving air pressure balance in the water tank device 100 and avoiding damage to the water tank device 100 due to overpressure or vacuum, thereby ensuring the safety and reliability of the water tank device 100.

[0043] In this embodiment, in the height direction of the box body 1, the vertical distance between the overflow port 12 and the bottom of the box body 1 is greater than half the height of the box body 1 to ensure the water storage function of the water tank device. In specific applications, the position of the overflow port 12 can be set according to water storage needs and is not limited here.

[0044] The water tank device 100 of this embodiment is provided with a float valve 3, which includes a connecting rod and a ball. The connecting rod is connected to the cover plate 2, and the connecting rod is provided with a channel. The accommodating chamber 11 is connected to the outside atmosphere through the channel. The ball is connected to the connecting rod and is located in the accommodating chamber 11, and the vertical distance between the ball and the cover plate 2 is less than the vertical distance between the overflow port 12 and the cover plate 2. When an abnormality occurs in the equipment and a large amount of water flows back into the water tank, the water level in the accommodating chamber 11 continues to rise and exceeds the overflow port 12, and the ball is blocked in the channel, thereby isolating the accommodating chamber 11 from the outside atmosphere. When the water level continues to rise, the pressure in the accommodating chamber 11 rises, and the water flows out of the overflow port 12 at an accelerated rate under the pressure, thereby preventing water from overflowing from the cover plate 2 and ensuring the normal operation of the equipment.

[0045] Reference Figure 1As shown, the water tank device 100 further includes a seal 5 and a fastener 6. The seal 5 is disposed at the connection between the cover plate 2 and the tank body 1. The fastener 6 is respectively disposed through the cover plate 2, the seal 5, and the tank body 1 to provide a sealed connection between the cover plate 2 and the tank body 1. The seal 5 and fastener 6 further prevent the liquid in the tank body 1 from leaking from the connection between the cover plate 2 and the tank body 1, ensuring the normal operation of the device.

[0046] Reference Figure 1 As shown, the cover plate 2 is also provided with a water injection port 22. The water tank device 100 also includes a water injection pipe 7 and a water injection valve 8. The water injection port 22 is connected to the water supply equipment through the water injection pipe 7. The water supply equipment is used to inject water into the accommodating chamber 11. The water injection valve 8 is connected to the water injection pipe 7 and is used to control the connection and disconnection of the water injection pipe 7. The water injection valve 8 has a built-in pressure reducing and stabilizing device. When the pressure in the water tank device 100 decreases, the water injection valve 8 automatically opens to replenish the water source and restore the system pressure to the set value; when the pressure reaches the set value, the water injection valve 8 automatically closes to avoid excessive water pressure. The water injection valve 8 also has a built-in check valve to prevent backflow when the water pressure decreases or stops during water replenishment, thereby ensuring stable operation of the equipment.

[0047] Reference Figure 1 As shown, the water tank device 100 further includes a return pipe 9, which passes through the return port 21 and has a first end 91 and a second end 92. The first end 91 is located outside the tank body 1 and is used to connect to the water-using device 300. The second end 92 is located inside the tank body 1. Along the height direction of the tank body 1, the vertical distance between the second end 92 and the bottom of the tank body 1 is less than half the height of the tank body 1, that is, D1 < 1 / 2D2, where D1 is the vertical distance between the second end 92 and the bottom of the tank body 1, and D2 is the height of the tank body 1.

[0048] In this embodiment, the vertical distance between the second end 92 and the bottom of the box body 1 is made less than half the height of the box body 1, thereby reducing the drop between the return water port 21 and the liquid level in the accommodating chamber 11, thereby reducing the impact force formed by the liquid flowing out of the second end 92, and further reducing the noise of falling water, so that the water tank device 100 can be used in a comfortable and quiet environment, thereby improving the applicability of the water tank device 100.

[0049] Reference Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a temperature control device provided in an embodiment of the present application. Based on this embodiment, a temperature control device 200 is also disclosed. This temperature control device 200 includes a circulating water pump 201, a piping assembly 207, and a water tank device 100 according to any of the above embodiments. One end of the circulating water pump 201 is connected to the water outlet 23 of the water tank device 100, and the other end of the circulating water pump 201 is connected to a water-using device 300 via the piping assembly 207. The water-using device 300 is connected to the return water inlet 21 of the water tank device 100 via the piping assembly 207.

[0050] During operation, the circulating water pump 201 drives the water in the water tank device 100 to flow from the water outlet 23 through the pipeline assembly 207 from the liquid inlet end of the water-using equipment 300 into the water-using equipment 300, and then flows from the liquid outlet end of the water-using equipment 300 through the pipeline assembly 207 from the return water port 21 back to the water tank device 100.

[0051] In this embodiment, the circulating water pump 201 is an immersion water pump, which is installed on the cover plate 2. The pump body of the immersion water pump is completely or partially immersed in the liquid, so that the circulating water pump 201 can directly pump water from the liquid without the need for an additional suction pipe. It has a simple structure, is easy to install, reduces energy loss, and improves work efficiency.

[0052] Reference Figure 2 As shown, the temperature control device 200 further includes a pressure sensor 205 and a controller. The pressure sensor 205 is disposed in the pipeline assembly 207 and is located at the input end of the water-using device 300, and is used to detect the pressure within the pipeline assembly 207. The controller is connected to the pressure sensor 205 and the circulating water pump 201, respectively, and is used to control the speed of the circulating water pump 201 based on the detection results of the pressure sensor 205. This prevents the pipeline from rupturing or leaking due to excessive pressure, and from reducing the water supply or causing abnormal operation and damage of the water pump due to insufficient pressure. The controller provides water at the required pressure to the water-using device, thereby ensuring the stability and safety of the temperature control device 200.

[0053] Reference Figure 2 As shown, the temperature control device 200 also includes a flow sensor 206, which is disposed in the pipe assembly 207 and located at the input end of the water-using device 300 and is used to detect the flow rate of water in the pipe assembly 207. A controller is connected to the flow sensor 206 and the circulating water pump 201, respectively, and is used to control the speed of the circulating water pump 201 based on the detection results of the flow sensor 206. This prevents excessive flow from causing pipe rupture and insufficient flow from reducing efficiency, thereby providing the water-using device with the required flow rate and ensuring the stable operation of the temperature control device 200.

[0054] Reference Figure 2As shown, temperature control device 200 also includes a heat exchanger 202, a heater 203, and a temperature sensor 204. The heat exchanger 202 is connected to the circulating water pump 201 and the water-using device 300 via a pipe assembly 207. Heat exchanger 202 is used to regulate the temperature of liquid entering water-using device 300. Heater 203 is connected to the heat exchanger 202 and the water-using device 300 via a pipe assembly 207. Heater 203 is used to heat liquid entering water-using device 300. Temperature sensor 204 is located in pipe assembly 207 at the input end of water-using device 300 and is used to detect the temperature of the water in pipe assembly 207. A controller is connected to temperature sensor 204, heat exchanger 202, and heater 203, respectively. Based on the detection results of temperature sensor 204, the controller controls the operation of heat exchanger 202 and heater 203, thereby providing water of the required temperature to water-using device 300 and improving operating efficiency.
