The drinking water device also includes a pressure gauge 8 for detecting the pressure in the pressure vessel 2, the pressure gauge 8 is connected to a controller, and the controller is also electrically connected to the exhaust valve 62.

[0025] The liquid outlet 22 of the pressure vessel 2 is connected to the water inlet end 11 of the water tank through a water supply pipeline 32, and a filter element assembly a is provided on the water supply pipeline 32. The filter element assembly a can be a single filter element or a composite filter element, and the water is filtered through the filter element assembly a; the filter element assembly a in this embodiment is mainly an activated carbon filter element, which is used to adjust the taste; and the water supply pipeline 32 is provided with a water inlet valve 64, and the water inlet valve 64 is located upstream of the filter element assembly a along the fluid flow path.

[0026] In this embodiment, the heating component 11b is an electric heater extending into the second water tank 11b, and a temperature controller 12b is provided in the second water tank 1b. A flow-through sterilizing lamp b is also provided upstream of the water outlet of the second water tank 1b; in addition, a sterilizing lamp c (which can be an ultraviolet sterilizing lamp) is also provided in the first water tank 1a. The second water tank 1b is placed below the first water tank 1a, that is, a third water outlet 14 is provided at the bottom of the first water tank 1a, which can allow the water in the first water tank 1a to flow into the second water tank 1b under the action of gravity. The third water outlet 14 of the first water tank 1a is connected to the second water tank 1b through a pipeline, and a third one-way valve 69 is provided on the pipeline.

[0027] The normal temperature water pipeline 33 is provided with a first drain valve 65, and the water outlet of the second water tank 1b is provided with a second drain valve 66. In addition, the second water tank 1b is also connected to a drainage pipeline 34, which is provided with a drain valve 68, and the outlet of the drainage pipeline 34 corresponds to the drain port 33e.

[0028] The booster pump 5, the water inlet valve 64, the first drain valve 65, the second drain valve 66 and the drain valve 68 are all electrically connected to the controller. In addition, the drinking water equipment also includes a water level detection module for detecting at least two different water levels in the first water tank 1a, a high water level gauge for detecting the high water level in the pressure vessel 2 and a low water level gauge for detecting the low water level in the pressure vessel 2. The water level detection module, the high water level gauge and the low water level gauge are all electrically connected to the controller. The water level detection module in this embodiment is a liquid level float, which is used to detect three water levels, which are respectively recorded as low water level, middle water level and high water level.

[0029] The working process of the drinking water equipment in this embodiment is as follows:

[0030] Water production process: First, the liquid level float in the first water tank 1a detects the water level signal in the first water tank 1a. If it is detected that the water level in the first water tank 1a is lower than the low water level, the booster pump 5 is turned on, the exhaust valve 62 is closed, the water inlet valve 64 is closed, the drain valve 68 is closed, the first drain valve 65 is closed, the overflow sterilization lamp b is closed, the second drain valve 66 and the heating component 11b are closed; when the high water level gauge in the pressure vessel 2 detects a signal, the exhaust valve 62 is opened until the pressure gauge 8 detects that the pressure in the pressure vessel 2 is 0.25MPa, the exhaust valve 62 is closed, and the water inlet valve 6 4 is opened, so that the water in the pressure container 2 will be sent to the first water tank 1a. After entering the first water tank 1a, the water will first enter the second water tank 1b. Because the second water tank 1b is installed below the first water tank 1a, due to gravity and water level difference, the water will first enter the second water tank 1b; if the water does not fill the water levels of the second water tank 1b and the first water tank 1a, and the pressure gauge in the pressure container 2 detects that the pressure is lower than 0.1MPa, the above water production process will be repeated until the water in the first water tank 1a is filled, that is, the high water level of the liquid level float detects the water level, and the water production process stops;

[0031] The water production process stops:

[0032] When the liquid level float in the first water tank 1a detects a high water level signal, the water inlet valve 64 is closed. At this time, if the low water level probe in the pressure vessel 2 detects a signal, water production needs to continue until the water in the first water tank 1a is filled up and the high water level is detected. At the same time, the pressure gauge 8 will detect the pressure every time the first water tank 1a is replenished. As long as the pressure is higher than 0.25MPa, the exhaust action will be performed, that is, the exhaust valve 62 will be opened until the pressure drops to 0.25MPa.

[0033] Heating process:

[0034] When the liquid level float in the first water tank 1a detects the middle water level, the heating component 11b in the second water tank 1b starts heating;

[0035] Water replenishment process in the first water tank 1a:

[0036] When the liquid level float in the first water tank 1a detects a low water level, the whole machine enters the water production process logic;

[0037] Emptying process:

[0038] If the system detects that the first drain valve 65 or the second drain valve 66 is not opened within the preset time, it is assumed that the water in the drinking water device has not been used within the preset time, so in order to ensure the freshness of the water in the future, the drain valve 68 will be opened to drain the water in the entire drinking water device until the liquid level of the first water tank 1a is detected to be low, and the drain valve 68 is closed;

[0039] Protection mechanism of drinking water equipment:

[0040] When the pressure gauge 8 in the pressure vessel 2 is damaged, the safety valve 63 will release the pressure to protect the pressure vessel 2. The safety valve pressure 63 is the default setting pressure, and the pressure will be automatically released when the pressure exceeds the limit.

[0041] A mechanical float is also provided in the first water tank 1a, which is activated only when the liquid level float fails;

[0042] A temperature sensor for detecting water temperature is also provided in the second water tank 1b, and the above-mentioned thermostat 12b is activated only when the temperature sensor fails.

[0043] Embodiment 2:

[0044] like Figure 2 As shown, different from the first embodiment, the water outlet end of the first water tank 1a in this embodiment is also connected to a water outlet pipe 34, and a heating component 11b is arranged on the water outlet pipe, and the water outlet end of the water outlet pipe 34 corresponds to the warm water outlet 33b. The second drain valve 66 and the overflow type germicidal lamp b are both arranged on the water outlet pipe 34. The heating component 11b is an instant heating heater, and the heating of the instant heating heater is a prior art, which will not be elaborated here.

[0045] Different from the first embodiment, the drinking water equipment in this embodiment is an instant hot drinking water equipment, and there is no second water tank in the drinking water equipment.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
