[0033] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] As Figures 1 to 4 shown, the embodiment of the present utility model provides a water tank assembly 10, including a box body 11, a channel assembly 12, a water outlet pipe 13, and a flow meter 14. The channel assembly 12 is arranged at the lower part of the side wall of the box body 11. The channel assembly 12 has a water outlet channel, and the water outlet channel has an inlet 1222 inside the box body 11 and an outlet 1212 outside the box body 11. It should be noted that being outside the box body 11 means being visible outside the box body 11, that is, the outlet 1212 can be seen outside the box body 11. The outlet 1212 can be flush with the outer surface of the box body 11 or protrude from the outer surface of the box body 11. The inlet 1222 faces upward and is higher than the bottom wall of the box body 11; the water outlet pipe 13 is arranged outside the box body 11 and is communicated with the outlet 1212; the flow meter 14 is arranged on the water outlet pipe 13. When the flow meter 14 can detect the flow, it indicates that the water in the box body 11 has not reached the lowest water level. When the flow meter 14 cannot detect the flow, it indicates that the water in the box body 11 has reached the lowest water level.

[0035] By setting the flowmeter 14 to determine whether the water level in the box body 11 reaches the lowest water level, the detection result is relatively accurate. Moreover, the flowmeter 14 is located outside the box body 11, so it will not affect the water in the box body 11 due to being immersed in the box body 11, nor will it affect its own structure due to being immersed in water.

[0036] Currently, in the prior art, the inlet 1222 and the outlet 1212 of the water outlet channel are generally coaxially arranged, and the axes of the inlet 1222 and the outlet 1212 are parallel to the horizontal direction, that is, the water outlet channel is arranged horizontally. Both the inlet 1222 and the outlet 1212 are vertical ports parallel to the vertical plane. If the water outlet channel is arranged in this way, it will cause the judgment time of the flowmeter 14 to be prolonged and dry burning to occur. Specifically, when the water level in the box body 11 drops to between the upper end and the lower end of the inlet 1222 of the water outlet channel in the vertical direction, water mixed with air will enter the water outlet channel, resulting in unstable signals of the flowmeter 14 and unable to make accurate judgments. It is not until the water in the box body 11 completely drops to the lower end of the inlet 1222 of the water outlet channel, that is, when the water in the box body 11 will not enter the water outlet channel at all, that the signal of the flowmeter 14 will be stable. At this time, the flowmeter 14 can judge that the water in the box body 11 has reached the lowest water level, which leads to a delay in the judgment of the flowmeter 14 and is prone to cause dry burning.

[0037] In this embodiment, in order to ensure that the flowmeter 14 can quickly and timely judge the water level, the water outlet channel is improved. The inlet 1222 is set to face upward and is higher than the bottom wall of the box body 11. Through this setting, when the water level in the box body 11 drops to the position of the inlet 1222, no more water will enter the water outlet channel. The flowmeter 14 can quickly judge that the lowest water level has been reached in the box body 11, ensuring the response speed of the flowmeter 14 and avoiding dry burning.

[0038] Specifically, in this embodiment, the water outlet channel includes a first channel 1221 and a second channel 1211 that are connected and communicate with each other. The axis of the first channel 1221 is parallel to the vertical direction or is set at an angle. The axis of the second channel 1211 is parallel to the horizontal direction or is set at an angle. The end of the first channel 1221 facing away from the second channel 1211 is the inlet 1222, and the end of the second channel 1211 facing away from the first channel 1221 is the outlet 1212. The inlet 1222 is not lower than the upper end of the outlet 1212. That is, on the basis of the original horizontal channel, a longitudinal channel is added to the water outlet channel, so that the inlet 1222 is higher than the outlet 1212, and at the same time, the inlet 1222 is a horizontal port basically parallel to the horizontal plane. Thus, once the water level drops to the inlet 1222, no more water will enter the water outlet channel from the inlet 1222.

[0039] Specifically, in this embodiment, the channel assembly 12 includes a water outlet portion 121 and a baffle 122. The water outlet portion 121 is disposed at the lower part of the box body 11. The water outlet portion 121 has a water outlet hole, and the water outlet hole is the second channel 1211. The baffle 122 is disposed inside the box body 11. The baffle 122 and the inner open end of the water outlet portion 121 enclose to form a first channel 1221. The lower end of the baffle 122 is fixed to the bottom wall of the box body 11. Optionally, the water outlet portion 121 and the box body 11 are of an integrally formed structure, which is convenient for processing. The water outlet portion 121 is an original structure of the box body 11. In this embodiment, only a baffle 122 needs to be added to the original structure, with a simple structure and low cost. Optionally, the baffle 122 is an arc-shaped plate, but it is not limited thereto.

[0040] Alternatively, in other embodiments, an opening may be formed in the bottom wall of the box body 11, and a water inlet pipe is provided at the opening position. One end of the water inlet pipe is communicated with the opening in the bottom wall, and the other end extends upward to form an inlet 1222. In this way, the inlet 1222 can also face upward and be higher than the bottom wall of the box body 11.

[0041] Optionally, the flow meter 14 is located at one end of the water outlet pipe 13 close to the outlet 1212. By arranging the flow meter 14 at one end of the water outlet pipe 13 close to the outlet 1212, the position of the flow meter 14 is close to the box body 11, so that the flow meter 14 can timely detect that there is no water flowing out of the box body 11, improving the response speed of the flow meter 14. Optionally, the flow meter 14 is a rotameter.

[0042] Furthermore, the water tank assembly 10 further includes a reminder device. The reminder device is used to send a reminder message when the flow meter 14 detects that the water level in the box body 11 is lower than the inlet 1222 (i.e., the lowest water level), so that the user can replenish water into the box body 11 as soon as possible. Optionally, the reminder device is a buzzer or a flash light, but it is not limited thereto.

[0043] As Figure 4 shown, an embodiment of the present invention further provides a water dispenser, which includes the water tank assembly 10 as described above, and further includes a water pump 20, a heating element 30 and a water vapor separator 40. The water pump 20, the heating element 30 and the water vapor separator 40 are all disposed on the water outlet pipe 13 of the water tank assembly 10 and are arranged in sequence along the direction of the water outlet pipe 13. The water in the box body 11 flows out after passing through the flow meter 14, the heating element 30 and the water vapor separator 40 in sequence under the action of the water pump 20. By adopting the above water tank assembly 10, the water level condition in the box body 11 can be timely detected, preventing dry burning.

[0044] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
