[0021] In one embodiment, Figure 1-2 As shown, a smart water dispenser for preventing cross infection includes a water dispenser body 100. The outside of the water dispenser body 100 is provided with a water cup placement plate and multiple water drinking outlets, and the inside of the water dispenser body 100 is provided with a water supply system and a controller; the water cup placement plate is divided into a disinfection area 11 and multiple water receiving areas 12, the disinfection area 11 and each water receiving area 12 are provided with a water cup sensor, an ultraviolet lamp is provided directly above the disinfection area 11, and a water drinking outlet is provided directly above each water receiving area 12; the water supply system is connected to each water drinking outlet respectively, and the controller is connected to the water supply system, the ultraviolet lamp and each water cup sensor respectively.

[0022] Among them, the controller is used to control the ultraviolet lamp to turn on to disinfect and sterilize the water cup when the water cup sensor detects that a water cup is placed in the disinfection area 11, until the preset disinfection time is reached or the water cup is detected to be taken away; and when the water cup sensor detects that a water cup is placed in the water receiving area 12, the controller is used to control the water supply system to supply water to the drinking water outlet directly above the water receiving area 12 until the preset water intake volume is reached or the water cup is detected to be taken away.

[0023] In a specific implementation, the cup placement plate is a support plate for placing cups.

A drinking water outlet can also be provided above the disinfection area 11 to supply water to the cups after disinfection.

[0024] The above embodiment provides an intelligent water dispenser for preventing cross infection, which divides the water cup placement plate into a disinfection area 11 with a water cup sensor and a water receiving area 12. It can automatically sense the placement of the water cup, automatically identify whether the water collection mode or the disinfection mode is based on the sensing result, and automatically perform the water collection or disinfection operation, thereby realizing intelligent operation; and the user does not need to touch the button switch when collecting water, but only needs to place the water cup in the water receiving area 12, realizing a contactless water collection function, avoiding the risk of cross infection caused by contact with viruses and bacteria and the spread of viruses due to hand contact; in addition, the water cup can also be disinfected and sterilized by ultraviolet light to more effectively prevent cross infection, thereby solving the problem of secondary contamination of the water outlet and the drinking cup of the water dispenser.

[0025] Based on the above embodiment, in another embodiment, the multiple drinking water outlets include a purified water outlet 21, a boiled water outlet 22 and a warm water outlet 23, the water supply system includes a water inlet 31, a filter device 32, a heating water tank 33 and a heat exchange device 34, the heat exchange device includes a cavity 341, an inner tube 342 and an outer tube 343; the water inlet 31 is connected to one end of the first water inlet valve 41 through the filter device 32, the other end of the first water inlet valve 41 is connected to the purified water outlet 21 through the purified water valve 45, and is connected to the first water inlet of the heating water tank 33 through the first high-temperature disinfection valve 43, and is connected to the second water inlet valve 42 is connected to one end of the outer tube 343, and the other end of the outer tube 343 is connected to the second water inlet of the heating water tank 33; the water outlet of the heating water tank 33 is connected to the boiled water outlet 22, and is connected to the purified water outlet 21 through the second high-temperature disinfection valve 44, as well as the upper end of the inner tube 342, and the lower end of the inner tube 342 is connected to the warm water outlet 23; the steam outlet of the heating water tank 33 is connected to the upper end of the cavity 341; the controller is respectively connected to the first water inlet valve 41, the second water inlet valve 42, the first high-temperature disinfection valve 43, the second high-temperature disinfection valve 44 and the purified water valve 45 to control the switching of the above-mentioned solenoid valves.

[0026] In this embodiment, the water supply system also includes a drain outlet 35; the lower end of the cavity 341 is connected to the drain outlet 35 through a steam exhaust valve 46 and a one-way valve 48; the lower end of the heating water tank 33 is connected to the drain outlet 35 through a sewage valve 47, and the one-way valve 48 is arranged between the steam exhaust valve 46 and the sewage valve 47; the controller is respectively connected to the steam exhaust valve 46, the one-way valve 48 and the sewage valve 47.

[0027] Among them, the first water inlet valve 41, the second water inlet valve 42, the first high-temperature disinfection valve 43, the second high-temperature disinfection valve 44, the purified water valve 45, the steam exhaust valve 46 and the sewage valve 47 are all solenoid valves controlled by controller signals. The filtering device 32 can adopt an RO machine, that is, a reverse osmosis water purifier (ROW), which is a device that filters raw water through reverse osmosis technology to remove impurities, heavy metals, bacteria, viruses and other harmful substances in the water. The working principle of the RO machine is based on a reverse osmosis membrane. This membrane selectively allows water molecules to pass through, while preventing macromolecules such as dissolved substances, colloids, bacteria, viruses from passing through, thereby achieving the purpose of purifying water. The RO machine usually adopts a multi-stage filtration system, including a PP cotton filter element, a granular activated carbon filter element, a compressed activated carbon filter element, an RO reverse osmosis membrane and a post-activated carbon filter element, etc., to ensure the safety and purity of the water quality. A heating component is provided on the heating water tank 33 for heating the water therein to obtain boiling water.

[0028] During specific implementation, you can pre-set the time for high-temperature disinfection or directly issue a high-temperature disinfection instruction. The high-temperature disinfection function of the water dispenser will be awakened and start to perform the high-temperature disinfection operation. The specific process of high-temperature disinfection is as follows:

[0029] First, the second water inlet valve 42, the purified water valve 45, and the drain valve 47 are closed, while the first water inlet valve 41, the first high-temperature disinfection valve 43, the second high-temperature disinfection valve 44, and the steam exhaust valve 46 are opened. The heated water tank 33 operates, producing boiling water and high-temperature steam. The high-temperature steam then enters the cavity 341 of the heat exchanger 34 and flows out through the steam exhaust valve 46, performing high-temperature steam disinfection on the pipes and valves connected to the purified water outlet 21. The disinfected wastewater is then discharged through the drain 35. Simultaneously, boiling water enters the inner tube 342 of the heat exchanger 34, performing high-temperature disinfection on the warm water outlet 23 and its outlet pipe. The disinfected wastewater is then discharged through the pipe to the drain 35. After the set high-temperature disinfection duration has expired, the high-temperature disinfection is stopped, the drain valve 47 is opened, and after all the water in the heated water tank 33 is drained through the drain 35, the drain valve 47 is closed. At this point, the high-temperature disinfection is completely completed, and the water dispenser automatically returns to normal water production.

[0030] In addition to using high-temperature water to disinfect and sterilize the drain pipe, the above-mentioned high-temperature disinfection operation also uses steam to perform high-temperature disinfection and sterilization on other pipes (such as water inlet pipes, drainage pipes, etc.), which can achieve disinfection and sterilization of the entire water supply system.

[0031] The intelligent water dispenser for preventing cross infection provided in the above embodiment, based on the functions of contactless water extraction and water cup disinfection, can also perform dual high-temperature disinfection and sterilization of each drinking water outlet, pipes and valves of the water supply system with high-temperature water and steam, and perform comprehensive disinfection treatment on the environment that may be secondary contaminated by the water dispenser, thereby completely eliminating the risk of cross infection.

[0032] In this embodiment, a water receiving tray 36 is provided below the cup placement plate. The cup placement plate is provided with a plurality of through holes. Excess water can flow into the water receiving tray 36 from the plurality of through holes to prevent the water flow from wetting the ground.

[0033] In this embodiment, the bottom of the water receiving tray 36 is connected to the drain port 35 through a pipe, so that waste water is discharged from the water dispenser body 100 through the drain port 35 to prevent the water in the water receiving tray 36 from overflowing.

[0034] In this embodiment, the outer tube 343 is wrapped around the outer side of the inner tube 342 and is disposed in the cavity 341 . Both the outer tube 343 and the inner tube 342 have a multi-section bending structure, which can more efficiently cool the water passing through the inner tube 342 .

[0035] In this embodiment, the water cup sensor is a gravity sensor.

[0036] In this embodiment, a display screen 37 is further provided on the outside of the water dispenser body 100 , and the display screen 37 is connected to the controller.

[0037] The display screen 37 may be a liquid crystal display screen 37 or a touch screen, and any display screen 37 product commonly used in the prior art may be used.

[0038] In specific implementation, the display screen 37 can be used to display water temperature and time, and can also be set to display other data according to actual needs, such as the working status of the water dispenser, so that the user can intuitively view the status of the water dispenser.

[0039] In the above-described embodiment, the specific structures, installation locations, and connection structures of the water cup sensor, ultraviolet lamp, filter device 32, heat exchange device 34, and display screen 37 are all prior art and will not be described in detail here.
