[0021] Reference Figure 1 As shown, Figure 1 A schematic diagram of the structure 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 water return port 21, and the water outlet 23 and the water return port 21 are respectively connected to the water-using equipment. The float valve 3 includes a connecting rod and a ball, and 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 .

[0022] 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 impurities such as dust 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, 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.

[0023] 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.

[0024] 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, 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 smaller 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 is accelerated to flow out from the overflow port 12 under pressure, thereby preventing water from overflowing from the cover plate 2 and ensuring the normal operation of the equipment.

[0025] Reference Figure 1 As shown, the water tank device 100 further includes a seal 5 and a fastener 6, and the seal 5 is arranged at the connection between the cover plate 2 and the box body 1. The fastener 6 is respectively penetrated through the cover plate 2, the seal 5 and the box body 1, so that the cover plate 2 is sealed and connected with the box body 1. The seal 5 and the fastener 6 further prevent the liquid in the box body 1 from leaking from the connection between the cover plate 2 and the box body 1, thereby ensuring the normal operation of the device.

[0026] 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 device through the water injection pipe 7. The water supply device 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 so that the system pressure returns to the set value; when the pressure reaches the set value, the water injection valve 8 automatically closes to avoid excessive water pressure. And the water injection valve 8 has a built-in check valve to avoid backflow when the water pressure decreases or stops during water replenishment, thereby ensuring the stable operation of the equipment.

[0027] Reference Figure 1As shown, the water tank device 100 also includes a return pipe 9, which is inserted into the return port 21, and is provided with a first end 91 and a second end 92, wherein the first end 91 is located outside the box 1 and is used to connect with the water-using device 300. The second end 92 is located inside the box 1. Along the height direction of the box 1, the vertical distance between the second end 92 and the bottom of the box 1 is less than half of the height of the box 1, that is, D1<1 / 2D2, wherein D1 is the vertical distance between the second end 92 and the bottom of the box 1, and D2 is the height of the box 1.

[0028] 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 height difference 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.

[0031] In this embodiment, the circulating water pump 201 is an immersion water pump 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 and is easy to install. It also reduces energy loss and improves work efficiency.

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 result of the pressure sensor 205, so as to avoid the situation that the pipeline pressure is too large to cause rupture or leakage, and the pipeline pressure is too small to cause the water supply to be reduced, the water pump is not operating normally and is damaged, and the water of the required pressure is provided to the water-using device, thereby ensuring the stability and safety of the temperature control device 200.

[0034] Reference Figure 2 As shown, the temperature control device 200 further includes a heat exchanger 202, a heater 203 and a temperature sensor 204. The two ends of the heat exchanger 202 are respectively connected to the circulating water pump 201 and the water-using device 300 through the pipeline assembly 207. The heat exchanger 202 is used to adjust the temperature of the liquid entering the water-using device 300. The two ends of the heater 203 are respectively connected to the heat exchanger 202 and the water-using device 300 through the pipeline assembly 207.
