[0049] Continue to refer to Figure 1 The water treatment device 10 further includes a heating device 30, which is used to provide hot water to the treatment tank 11. The inlet 31 of the heating device 30 is connected to the first outlet 22, and the outlet 32 ​​of the heating device 30 is connected to the first inlet 21.

[0050] In this embodiment, the heating device 30 heats the water flowing into the treatment tank 11, providing a high-temperature water flow. The high-temperature water flow enters the treatment tank 11 and disinfects the activated carbon 12 at high temperature, thus having a disinfection and sterilization effect.

[0051] The heating device 30 employs a heat exchanger. In this embodiment, the heating device 30 employs a plate heat exchanger. In other embodiments, the heating device 30 may also employ other heat exchange devices such as shell-and-tube heat exchangers or jacketed heat exchangers.

[0052] Specifically, the plate heat exchanger also includes a heat exchange fluid inlet 33 and a heat exchange fluid outlet 34. The high-temperature heat exchange fluid enters the plate heat exchanger from the heat exchange fluid inlet 33 and exchanges heat with the water to be heated, thus heating the water. The heated water enters the treatment tank 11 through the first inlet 21, rinses the activated carbon 12, and then flows out of the treatment tank 11 from the first outlet 22. It then enters the heat exchanger again to exchange heat with the heat exchange fluid and raise its temperature. This cycle is repeated to continuously rinse the activated carbon 12, thereby disinfecting and desorbing the activated carbon 12.

[0053] In this embodiment, a filter 35 is also provided between the inlet 31 and the first outlet 22 of the heating device 30.

[0056] In this embodiment, a pump (not shown) is also provided between the inlet 31 and the first outlet 22 of the heating device 30, which provides power for the water flow from the first inlet 21 to the first outlet 22.

[0057] The water treatment device 10 further comprises a controller (not shown) electrically connected with the temperature detector 36 and the heating device 30, which is used to receive the temperature data of the temperature detector 36 and control the working of the heating device 30 according to the temperature data.

[0058] In this embodiment, a timer (not shown) is further included, and the controller is electrically connected with the timer, which is used to control the working of the heating device 30 according to the signal sent by the timer.

[0059] Specifically, the temperature detector 36 detects the temperature of the water flow flowing out of the first water outlet 22 and sends the temperature data to the controller, when the temperature is lower than the first preset temperature, the controller controls the heating device 30 to continue heating until the temperature of the water flow reaches the first preset temperature, and then the controller controls the heating device 30 to enter the heat preservation state, the water entering the treatment tank 11 is always kept above the first preset temperature, and at the same time the timer starts timing; after the time of the heat preservation state reaches the preset heat preservation time, the timer sends a signal to the controller, and the controller controls the heating device 30 to enter the cooling state; the temperature detector 36 continues to detect the temperature of the water flow, and when the temperature is lower than the second preset temperature, the controller controls the heating device 30 to stop working, and the desorption and regeneration process of the activated carbon 12 is completed.

[0060] The preset heat preservation time is in the range of 1-3 hours; when the heating device 30 is in the heat preservation state, the water entering the treatment tank 11 is high-temperature hot water, and this stage is the main stage for high-temperature sterilization and desorption regeneration of the activated carbon 12, so the time is controlled in the range of 1-3 hours, which can not only ensure that the activated carbon 12 basically completes the regeneration process, but also can avoid energy waste caused by too long time.

[0061] When the heating device 30 is in the heating state and the heat preservation state, the heat exchange liquid inlet 33 flows in high-temperature heat exchange liquid such as hot water; when the heating device 30 is in the cooling state, the heat exchange liquid inlet 33 flows in low-temperature heat exchange liquid such as cold water or ice water.

[0062] In this embodiment, the first preset temperature is 95℃, and high-temperature water flow is beneficial to disinfect the activated carbon 12; the second preset temperature is 40℃, and the water flow temperature continues to decrease and cannot play a high-temperature disinfection role.

[0065] The gas provided by the gas supply device 40 has a pressure of 0.5 bar to 2 bar. The pressure of the gas entering the treatment tank 11 does not need to be too high, and can meet the requirement of driving the desorption substances to float to the vicinity of the gas outlet 23, and the lower pressure is more economical and has lower cost.

[0066] In the embodiment, a gas pressure gauge 41 is arranged between the gas outlet of the gas supply device 40 and the first water inlet 21, for monitoring the pressure of the gas entering the treatment tank 11, so that the pressure of the gas is within a preset range.

[0067] In the embodiment, an air inlet valve 410 is further arranged on the connecting pipeline between the gas pressure gauge 41 and the first water inlet 21, and the air inlet valve 410 is used for controlling the opening and closing of the air inlet pipeline.

[0068] In the embodiment, the controller is further electrically connected with the gas supply device 40, for controlling the opening or closing of the gas supply device 40.

[0069] In the specific implementation, when the water flow temperature detected by the temperature detector 36 reaches the first preset temperature, the disinfection and desorption process of the activated carbon 12 is formally started, the controller controls the gas supply device 40 to be opened, the gas supply device 40 starts to input the gas into the treatment tank 11, and the gas flow carries the desorption substances from the bottom to the top together with the water flow; when the water flow temperature detected by the temperature detector 36 is lower than the second preset temperature, the disinfection and desorption process of the activated carbon 12 is completed, and the controller controls the gas supply device 40 to be closed, so as to stop the gas supply, and the use of the gas is more efficient and economical.

[0070] In other embodiments, the gas supply device 40 can also be manually opened or closed.

[0071] Correspondingly, the utility model embodiment further provides a packaged water, which comprises a packaging container and drinking water, the packaging container is used for containing the drinking water, and the drinking water is output by the above water treatment device.
