DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] Embodiment 1

[0031] like Figure 1 and Figure 2 As shown, a circulating heating water storage device includes a water tank body 1, wherein the water tank body 1 is a prior art and is used to store heated water, and the water tank body 1 also has the function of heat preservation, which can keep the heated water warm so that the user can use the hot water in time, and can also save energy. A control panel 2 is arranged on the front of the outer surface of the water tank body 1, and a display screen 3 for display is arranged on the front of the control panel 2. Both the control panel 2 and the display screen 3 are prior art and can display the temperature and volume of the water in the water tank body 1, which is convenient for the user to check. A pressure relief component 4 is also arranged inside the control panel 2, and a return water component 6 adapted to the pressure relief component 4 is also arranged at the lower end of the control panel 2.

[0032] In addition, a water inlet pipe 7 and a water outlet pipe 8 communicating with the interior of the water tank body 1 are also provided at the lower end of the control panel 2. A solenoid valve [not shown in the figure] is also provided at the connection between the water inlet pipe 7 and the water tank body 1. The battery valve is a prior art. The control panel 2 controls the opening and closing of the solenoid valve. When the solenoid valve is opened, cold water can enter the water tank body 1 through the water inlet pipe 7. When the solenoid valve is closed, cold water cannot enter the water tank body 1 through the water inlet pipe 7.

[0033] like Figure 3 - Figure 5 As shown, the pressure relief assembly 4 includes a pressure relief pipe 41 fixed inside the control panel 2, and an adjusting rod 42 is threadedly installed on the front end of the pressure relief pipe 41. The adjusting rod 42 is threadedly connected to the pressure relief pipe 41 so that the adjusting rod 42 can move forward and backward relative to the pressure relief pipe 41 when it rotates, and a sliding disk 43 is rotatably installed on the rear end of the adjusting rod 42. The adjusting rod 42 is rotatably connected to the sliding disk 43 so that the sliding disk 43 can also move forward and backward when the adjusting rod 42 moves forward and backward, but it will not rotate with the rotation of the adjusting rod 42, and a return spring 44 is fixed to the rear end of the sliding disk 43, and a truncated cone-shaped sealing block 45 is fixed to the rear end of the return spring 44. A sealing platform 46 adapted to the sealing block 45 is also fixed to the rear side of the inner cavity of the pressure relief pipe 41. Since the cross-sections of the sealing block 45 and the sealing platform 46 are both truncated cone-shaped, the contact area between the sealing block 45 and the sealing platform 46 can be increased, thereby achieving a better sealing effect and preventing the device from releasing pressure when sufficient pressure is not reached, thereby affecting the normal operation of the device.

[0034] When the side wall of the sealing block 45 is tightly fitted with the side wall of the sealing platform 46, the water vapor in the pressure relief pipe 41 cannot enter the pressure relief pipe 41 through the second water inlet pipe 47. When the side wall of the sealing block 45 is not in contact with the side wall of the sealing platform 46, the water vapor in the second water inlet pipe 47 will enter the pressure relief pipe 41 through the gap between the sealing block 45 and the sealing platform 46, and then be discharged through the second water outlet pipe 48, thereby completing the pressure relief. The sealing platform 46 can also limit the sealing block 45. When the adjusting rod 42 moves to the side close to the sealing block 45, the sliding plate 43 will also move to the side close to the sealing block 4 5 moves to one side, thereby shortening the distance between the sliding disk 43 and the sealing block 45. Since a return spring 44 is arranged between the sliding disk 43 and the sealing block 45, the return spring 44 can be compressed to adjust the elastic force of the return spring 44. When the sliding disk 43 is located at the frontmost position, the elastic force of the return spring 44 is the smallest, so that a small pressure in the water tank body 1 can push the sealing block 45 forward. When the sliding disk 43 is located at the rearmost position, the elastic force of the return spring 44 is the largest, so that a large pressure in the water tank body 1 can push the sealing block 45 forward.

[0035] In addition, a water inlet pipe 47 communicating with the interior of the water tank body 1 is fixed to the rear end of the pressure relief pipe 41, and the end of the sealing platform 46 away from the pressure relief pipe 41 is located at the upper part of the inner cavity of the water tank body 1 (such as Figure 8 As shown), when the pressure in the water tank body 1 is greater than the set value, the water vapor in the water tank body 1 can enter the pressure relief pipe 41 through the sealing platform 46, and because the other end of the sealing platform 46 is designed to be at the upper part of the inner cavity of the water tank body 1, the water vapor in the water tank body 1 can be discharged, reducing the water spraying during pressure relief. A water outlet pipe 48 is also provided at the lower part of the outer surface of the pressure relief pipe 41. A thermostatic switch 49 is fixed to the front end of the pressure relief pipe 41, and a knob 50 is also fixed to one end of the thermostatic switch 49. When the knob 50 is rotated, it is connected with the thermostatic switch 49 to adjust the temperature of the water in the water tank body 1. The knob 50 is slidably connected to the adjusting rod 42, so that when the knob 50 is rotated, the adjusting rod 42 can be driven to rotate, and the sliding plate 43 can also slide back and forth relative to the knob 50, so that when the device adjusts the temperature of the water in the water tank body 1, the sliding plate 43 can move back and forth.

[0036] The specific implementation of this embodiment is as follows: the device adjusts the temperature of the water heater according to different usage conditions when in use. When the user rotates the knob 50, the thermostat 49 can adjust the temperature of the water in the water tank body 1 through the connection between the knob 50 and the thermostat 49. In addition, due to the sliding connection between the knob 50 and the regulating rod 42, the knob 50 can also drive the regulating rod 42 to rotate. Then, through the connection between the regulating rod 42 and the pressure relief pipe 41 and the sliding plate 43, the sliding plate 43 can be moved back and forth, thereby further adjusting the elastic force of the return spring 44.

[0037] When the pressure in the water tank body 1 is too high, the sealing block 45 can be pushed forward to allow the water or gas in the water tank body 1 to be discharged to the outside through the water inlet pipe 47, the pressure relief pipe 41, and the water outlet pipe 48 in turn, thereby achieving the purpose of pressure relief. In addition, due to the connection between the temperature control switch 49 and the knob 50, the device can adjust the pressure during pressure relief according to the different temperatures in the water tank body 1 when in use [for example, at this time, the water tank body 1 is filled with an equal amount of water. According to the principle of thermal expansion and contraction, the pressure in the barrel at 50°C is different from the pressure in the barrel at 100°C, so the pressure during pressure relief is also different. Therefore, the setting of the pressure relief component 4 is used to adjust different pressure relief pressures according to different set pressures].

[0038] When the water temperature approaches the critical value that may produce excessive pressure, appropriately lower the pressure relief pressure setting value to allow the water heater to discharge some hot water in time and release the pressure, effectively avoiding serious safety accidents such as water heater explosion caused by excessive pressure.

[0039] Embodiment 2

[0040] This embodiment further improves the water return component 6 on the basis of the first embodiment, so that the device can separate water vapor when the pressure is released to prevent the water vapor from spraying randomly, making the device more stable and safer to use.

[0041] like Figure 6 - Fig. 9 As shown, the return water component 6 includes a return water pipe 61 fixed to the lower end of the control panel 2, and the return water pipe 61 is connected to the outlet pipe 48 through a connecting pipe 62, so that the water vapor discharged from the outlet pipe 48 can enter the return water pipe 61 through the connecting pipe 62, and a truncated cone 63 with upper and lower openings is fixed to the upper part of the outer surface of the return water pipe 61, and the truncated cone 63 is set with a small bottom and a large top. When the water vapor discharged through the pressure relief component 4 enters the return water pipe 61 through the connecting pipe 62, due to the high-pressure injection, the water vapor can be injected into the side wall of the truncated cone 63. Due to the different densities of gas and liquid, when the liquid and gas are mixed and flow together, if an obstruction is encountered, the gas will be deflected and go away, while the liquid continues to have a forward speed due to inertia. The forward liquid adheres to the blocking filler and is gathered downward due to the action of gravity. The gas passes through the opening of the truncated cone 63 and is discharged from the exhaust port 64.

[0042] In addition, an exhaust port 64 is provided at the upper end of the return pipe 61, and a water tank 65 is fixed at the lower end of the return pipe 61. The water tank 65 is used to store the collected water. Due to the design of the one-way valve 66, it can prevent the pressure in the pipeline from causing the liquid in the water tank 65 to return to the return pipe 61 again when the device injects cold water into the water tank body 1, thereby affecting the normal operation of the device. A one-way valve 66 is provided between the return pipe 61 and the water tank 65 and the connecting pipe 62. The water tank 65 is connected to the water inlet pipe 7 by a pipeline, and the other end of the water tank 65 also needs to be connected to a water pipe, so that when the device injects cold water into the water tank body 1, the cold water will first pass through the water tank 65 and be injected into the water tank body 1 with the water stored in the water tank 65, thereby reducing the waste of water resources and preventing water from spraying to the outside.

[0043] When the device is in use, the cold water injected into the device will pass through the water tank 65. When there is no need to inject cold water, the water tank 65 will be filled with cold water. Due to the design of the one-way valve 66, the cold water will not be allowed to enter the return pipe 61 from the water tank 65. Due to the principle that the pressure is low where the flow rate is high, when the device is depressurized, it will have a large pressure, which will press the water downward, allowing the water to enter the water tank 65 through the one-way valve 66. At this time, the water pressure in the pipeline will increase, and when cold water is injected into the water tank body 1, the water generated by the pressure relief will follow the cold water into the water tank body 1, reducing water waste. At the same time, it will not spray everywhere, preventing high-temperature and high-pressure water vapor from spraying onto the user or the ground, making the device more stable and safer when in use.

[0044] The specific implementation of this embodiment is as follows: when the pressure in the water tank body 1 is too high, the pressure relief assembly 4 will release the pressure, and the water vapor in the water tank body 1 will be discharged from the water outlet pipe 48, and then enter the water return pipe 61 through the connecting pipe 62. Due to the high-pressure injection, the water vapor can be injected to the side wall of the truncated cone tube 63. Due to the different densities of gas and liquid, when the liquid and gas are mixed and flow together, if there is an obstacle, the gas will be deflected and go away, while the liquid continues to have a forward speed due to inertia. The forward liquid adheres to the blocking filler and is gathered together downward due to the action of gravity, and is stored in the water storage tank 65 through the one-way valve 66. The gas passes through the opening of the truncated cone tube 63 and is discharged from the exhaust port 64;

[0045] When cold water needs to be injected into the water tank body 1, since the water pipe is always in an open state, cold water is then injected into the water tank body 1 by controlling the solenoid valve. Due to the design of the one-way valve 66, the cold water will not enter the water storage tank 65. The water stored in the water storage tank 65 will be re-injected into the water tank body 1 along with the cold water, reducing the waste of water resources.

[0046] It should be noted that the specific installation method, circuit connection method and control method of the water tank body 1, the control panel 2 and the display screen 3 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0047] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
