In some exemplary embodiments, as shown in fig. 10 and 11, when the water tank 3 is placed in the fixing cylinder 203, the cover 302 of the water tank 3 may be flush with the display panel 15 at the top of the housing, and the handle 303 of the water tank 3 may be supported at the top end of the barrel 401 of the housing 4, so as to facilitate the water tank to be taken and placed. The water dispenser further comprises a residual water box 14, the residual water box 14 is detachably connected to the base 1 and is arranged opposite to the water outlet nozzle 7, a water permeable hole 1401 is formed in the top surface of the residual water box 14, and the residual water box 14 is used for collecting water which is carelessly scattered during water receiving. In this example, as shown in fig. 10, magnets 23 are provided inside both the residual water tank 14 and the base 1, and both are fixed by magnetic attraction of the magnets 23, so that the residual water tank 14 can be conveniently detached.

In some exemplary embodiments, as shown in fig. 12a and 12b, the water tank assembly may further include a float cover 16 fixed to the bottom inside the water tank 3 and a float 17 movably disposed inside the float cover 16, wherein the float 17 is configured to be in a first position (the position shown in fig. 12 a) when the water level inside the water tank 3 is higher than the minimum water level and configured to be in a second position (the position shown in fig. 12 b) when the water level inside the water tank 3 is lower than the minimum water level. The electronic control system may further comprise a water level switch 18 disposed on an outer wall of the fixed cylinder 203, the water level switch 18 may be fixed in a clamping groove 2032 (shown in fig. 6 a) disposed on the outer wall of the fixed cylinder 203, and the water level switch 18 is configured to be turned on when the float 17 is in the first position and configured to be turned off when the float 17 is in the second position. When the water level switch 18 is in a communicated state, the water level in the water tank 3 is in a water level range of normal water making of the water dispenser, and the water dispenser can work normally after being electrified; when the water level switch 18 is in an off state, it indicates that the water level in the water tank 3 is too low, the water dispenser stops producing water, and "water shortage" can be displayed to remind a user to add water to the water tank 3. In this example, the float cover 16 may be engaged with a locking rib 3013 (shown in fig. 5 b) provided on the inner bottom surface of the tank body 301 of the water tank 3 to achieve fixation. The float cover 16 is provided with an opening so that water in the water tank 3 can enter the float cover 16 and the float 17 can rise and fall according to the height of the water level.

In some exemplary embodiments, as shown in fig. 13a, 13b, and 13c, a through hole 2012 is provided on the first partition 201 corresponding to the water outlet 3012 of the water tank 3, and the water outlet seat 6 is fixed at the through hole 2012. The water tank component further comprises a check valve 19 and an elastic part 20 which are arranged at the position of the water tank water outlet 3012, and the elastic part 20 is arranged between the check valve 19 and the water tank 3. The check valve 19 is arranged to abut against the water outlet seat 6 and open the water outlet 3012 of the water tank 3 when the water tank 3 is placed in the fixed cylinder 203, the elastic member 20 is arranged to be compressed when the water tank 3 is placed in the fixed cylinder 203, and the check valve 19 is arranged to block the water outlet 3012 of the water tank 3 by utilizing self elasticity after the water tank 3 is separated from the fixed cylinder 203. The water outlet seat 6 may be provided with a holding groove 601, a boss 602 is provided in the holding groove 601, and the water inlet 603 of the water outlet seat 6 is disposed at the top end of the boss 602. The water outlet 3012 of the water tank 3 protrudes out of the bottom surface of the water tank 3, the water outlet 3012 of the water tank 3 extends out of the through hole 2012 to the inside of the accommodating groove 601 and is sleeved outside the boss 602, the check valve 19 abuts against the top end of the boss 602 and opens the water outlet 3012 of the water tank 3, and a sealing ring 21 is arranged between the outer wall of the water outlet 3012 of the water tank 3 and the inner wall of the accommodating groove 601 to prevent water from flowing into the inside of the water dispenser. In this example, the elastic member 20 may be a spring, the check valve 19 includes a head portion and a body portion, the head portion of the check valve 19 is located on one side of the bottom wall of the water tank 3 facing the inside of the water tank 3, and the body portion is located in the water tank water outlet 3012. The spring cover is established at the body of check valve 19, when water tank 3 was placed in fixed cylinder 203 (namely water tank 3 was in the state of placing shown in fig. 13 a), goes out the boss 602 of water seat 6 and upwards jacks up check valve 19, and the head of check valve 19 does not contact with water tank 3, and then the delivery port 3012 of water tank 3 is opened, and water in the water tank 3 can be followed delivery port 3012 and flow out, and under this state, the spring is the compression form, and the one end butt of spring is on the spacing ring that the one end of keeping away from the head of check valve 19 body set up, and the other end butt is on the diapire of water tank 3. After the water tank 3 is separated from the fixed cylinder 203 (i.e. the water tank 3 is in the lifted state shown in fig. 13 c), because the check valve 19 is not abutted on the boss 602 of the water outlet base 6, the head of the check valve 19 is abutted on the bottom wall of the water tank 3 under the elastic force of the spring and blocks the water outlet 3012 of the water tank 3, so that the water in the water tank 3 cannot flow out. The check valve 19 and the elastic member 20 are disposed at the water outlet 3012 at the bottom of the water tank 3, and the check valve 19 is matched with the water tank outlet 3012, the elastic member 20 and the water outlet base 6, so that the water outlet 3012 of the water tank 3 can be opened when the water tank 3 is in a standing state, and the water outlet 3012 of the water tank 3 can be closed when the water tank 3 is in a taking state, thereby preventing residual water stored in the water tank 3 from leaking after the water tank 3 is taken out.

In some exemplary embodiments, the working process of the water dispenser of the embodiments of the present invention may be:

(1) when a user fills the water tank 3 and places the water tank at the installation position of the water tank (water can be directly poured into the water tank 3 or the water tank 3 is taken down for receiving water), the check valve 19 at the water outlet 3012 of the water tank is pushed open by the water outlet seat 6, the water path is connected, meanwhile, the floater 17 in the water tank 3 rises to the highest position to be opposite to the position of the water level switch 18, the water level switch 18 is communicated, and the water dispenser can normally work after being electrified. When a user takes water through the operation display panel 15, water in the water tank 3 is extracted by the water pump 8 and enters the heater 10 through the water outlet seat 6, the water pump 8 and the water valve 9 in sequence, and the heater 10 immediately heats the water to the temperature and the volume required by the user and flows out through the water outlet nozzle 7 within 3 seconds;

(2) along with the gradual water intake of the user, the water level in the water tank 3 gradually descends, when the position of the floater 17 which descends into the water tank 3 is not opposite to the position of the water level switch 18, the water level switch 18 is switched off, the machine stops water production, and simultaneously displays 'water shortage' to remind the user of adding water.

The water valve 9 can adopt a one-way valve, so that when the water dispenser is used and a user takes away the water tank 3 and does not put back for a long time, the one-way valve can effectively prevent water in the heater 10 from flowing back into the water dispenser, thereby avoiding potential safety hazards and poor user experience.
