[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] refer to Figure 1-3 , an intelligent water vending machine, including a chassis 1, a door 11 is installed on the chassis 1, a water tank 2, a filter module 4 connected to the water tank 2 and a water outlet pipe 21, a control host 3 are installed inside, and the filter module 4 is also connected to an external water inlet pipe 22. Since the advertising display screen 12 and the control panel 13 contain many components and have a certain weight, if they are installed on the door 11, there are certain requirements for the waterproof performance treatment of the edge of the door 11, the connection between the door 11 and the chassis 1, and the overall strength of the door 11, which increases the difficulty of making the door 11. Therefore, the advertising display screen 12, the control panel 13 and the water filling station are installed on the front of the chassis 1, and the door 11 is installed on the side of the chassis 1, so that there are no other components on the door 11, reducing its negative pressure. The control panel 13 can be set with card swiping, balance display, hot and cold cases and indicator lights, etc., and is electrically connected to the control host 3 for control.

[0024] refer to Figure 2-3 as well as Figure 5, the first RO reverse osmosis module 5 connected between the filter module 4 and the water storage tank 2 is installed in the chassis 1, and the second RO reverse osmosis module 6 is installed on the water outlet pipe 21, so that the external water source passes through the filter module 4, the first RO reverse osmosis module 5, the water storage tank 2, and the second RO reverse osmosis module in sequence, and finally flows out from the water outlet pipe 21. It can be understood that the RO reverse osmosis module 6 is a prior art, which has the function of converting high-concentration water into low-concentration water, and at the same time completely isolates industrial pollutants, heavy metals, bacteria, viruses and other impurities mixed in the water in large quantities, so as to achieve the physical and chemical indicators and hygiene standards specified for drinking. The water inlet pipe 22 is connected to the external water source and can be pumped into the filter module 4 through the pump body. The first RO reverse osmosis module 5 and the second RO reverse osmosis module 6 are set, and the water can be reverse osmotic once before entering the water storage tank 2, and reverse osmosis is performed again when the water storage tank 2 is discharged, so as to achieve double reverse osmosis and ensure the purity of the water.

[0025] In some embodiments, reference Figure 2-3 , a heat preservation lamp 81 and a temperature sensor 8 for sensing temperature to control the switch of the heat preservation lamp 81 are also installed in the chassis 1, and a heat preservation layer 9 is installed on the inner wall of the chassis 1. It can be understood that the temperature sensor 8 is electrically connected to the control host 3. For example: the standard temperature is set to 5 degrees Celsius. At this time, when the temperature sensor 8 senses that the temperature in the chassis 1 is less than or equal to 5 degrees Celsius, the signal is fed back to the control host 3, and the control host 3 controls the heat preservation lamp 81 to turn on the light. Since the closer to the heat preservation lamp 81, the higher the temperature, the temperature sensor 8 is installed at a position away from the heat preservation lamp 81, such as the bottom of the chassis 1 or on the side wall near the bottom of the chassis 1. The heat preservation layer 9 is made of foam cotton or heat preservation cotton, and the heat preservation layer 9 is attached to the inner walls inside the chassis 1, which can effectively prevent temperature loss.

[0026] refer to Figure 1-2 The water filling station includes a barrel storage bin 7, one side of which is open and located on the front of the chassis 1, and a closed door 71 is installed at the opening, and the outlet of the water outlet pipe 21 is installed on the top of the barrel storage bin 7. It can be understood that when water needs to be filled, the closed door 71 is opened, and the barrel is placed in the barrel storage bin 7. The opening of the barrel corresponds to the outlet of the water inlet pipe 22, and water is collected by swiping a card on the control panel 13. Further, two water filling stations are installed.

[0027] refer to Figure 4 and Figure 6, a pump body and a flow valve are installed on both the water inlet pipe 22 and the water outlet pipe 21. Furthermore, a liquid level sensor 23 is installed in the water storage tank 2, and the liquid level sensor 23 is electrically connected to the control host 3 to control the flow valve on the water inlet pipe 22. It can be understood that the pump body and the flow valve on the water pipe control the water output. The liquid level sensor 23 is installed on the side wall near the bottom of the water storage tank 2. When the liquid level is lower than the liquid level sensor 23, the liquid level sensor 23 is fed back to the control host 3. The control host 3 controls the main body on the water inlet pipe 22 to work, and the external water source is pumped into the water storage tank 2. When the flow valve calculates and controls the amount of water passing through to reach the saturation of the water storage tank 2, the pump body on the water inlet pipe 22 ends.

[0028] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
