Furthermore, some technical features that are known in the art have not been described in detail in order to avoid obscuring the utility model.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present utility model. It will be apparent that embodiments of the utility model may be practiced without limitation to the specific details that are set forth by those skilled in the art. Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

The embodiment of the utility model provides a water dispenser. The water dispenser provided by the utility model can be used for providing drinking water with different temperatures. Hereinafter, a water dispenser according to an embodiment of the present utility model will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 3 in combination, the water dispenser of the present utility model may include a body (not shown), a normal temperature water tank 110, and a heating water tank 120. The heating water tank 120 may be a water storage tank (abbreviated as a hot tank) having a heating element. Both the normal temperature water tank 110 and the heating water tank 120 may be provided on the machine body. The normal temperature water tank 110 may be disposed on the machine body to be upper than the heating water tank 120, and the heating water tank 120 may be disposed on the machine body to be lower than the normal temperature water tank 110. The normal temperature water tank 110 can be provided with a water outlet 111, the heating water tank 120 can be provided with a water inlet 121, the water inlet 121 is lower than the water outlet 111, and the water outlet 111 and the water inlet 121 can be communicated through a first pipeline 130. This ensures that water in the normal temperature water tank 110 can be supplied to the heating water tank 120 by gravity. The first pipe 130 may be provided with a control valve 140, and the control valve 140 may include a valve body 141 and a valve body 142. The valve body 141 encloses a valve cavity 145, the valve core 142 is at least partially disposed in the valve cavity 145, and the valve core 142 is configured to be movable between a first position and a second position relative to the valve body 141 along with the lifting of the liquid level in the valve cavity 145, and the first pipeline 130 can be closed when the valve core 142 moves to the first position and can be opened when the valve core 142 moves to the second position. The density of the valve element 142 may be less than that of water, the valve element 142 may be made of PP material, although other materials less than that of water are not excluded. Here, the second position is not limited to one specific position, and may be all positions apart from the first position on the movement path of the spool 142.

When the water in the heating water tank 120 (generally, hot water is generally referred to as hot water for the sake of distinction hereinafter), too much water in the heating water tank 120 overflows from the water inlet 121 into the valve cavity 145 of the control valve 140, when water exists in the valve cavity 145, the valve core 142 moves upwards under the buoyancy effect, and when the liquid level in the valve cavity 145 rises to a specified high position (such as a first position), the first pipeline 130 is closed, so that the hot water cannot continue to flow upwards. When hot water is discharged from the heating water tank 120, the hot water in the valve chamber 145 also falls, so that the liquid level in the valve chamber 145 decreases, the valve spool 142 moves downward, and the first pipe 130 is opened when the liquid level in the valve chamber 145 decreases to a specified low position (e.g., a second position).

According to the water dispenser, the water inlet 121 is lower than the water outlet 111, the water outlet 111 is communicated with the water inlet 121 through the first pipeline 130, and the on-off of the first pipeline 130 is controlled through the lifting of the liquid level in the valve cavity 145, so that water can be automatically replenished to the heating water tank 120 by means of gravity, hot water is prevented from flowing back into the normal-temperature water tank 110 from the heating water tank 120, the structure of the control valve 140 is simple, and the manufacturing cost is reduced.

The valve spool 142 may have a head 1421, the head 1421 may block the first port 143 when the valve spool 142 moves to the first position, and may open the first port 143 when the valve spool 142 moves to a position away from the first position (all positions after the position away from the first position may be collectively referred to as the second position). So set up, realize first pipeline 130 break-make through the cooperation of head 1421 and first mouth 143 for control valve 140 overall structure is simpler. The first port 143 may be circular, but may be other shapes, etc. In order that the head portion 1421 may completely block the first port 143, the head portion 1421 may have a hemispherical shape, and of course, the head portion 1421 may have other shapes, such as a plate shape, etc. Specifically, as the liquid level in the valve chamber 145 rises, the valve element 142 rises with the buoyancy force as the liquid level rises until the head 1421 of the valve element 142 blocks the first port 143, and the liquid level stops rising. It should be appreciated that the first position may be a specific position, as shown in fig. 3, where the head 1421 abuts against the first port 143 to block the first port 143, and the second position is not limited to a specific position, but all positions where the head 1421 is separated from the first port 143 to open the first port 143.

So set up, when the case 142 is positioned at the second port 144, the first pipeline 130 is still in a conducting state, and the connecting part 1422 is connected below the head 1421, so that the case that the head 1421 cannot block the first port 143 due to the fact that the case 142 rotates along with the liquid level lifting process in the valve cavity 145 is avoided. When the valve core 142 is disposed in the valve cavity 145, the connecting portion 1422 may be located below the head 1421, so as to avoid the situation that the head 1421 seals the second port 144 below. The cross-sectional area of the connecting portion 1422 may be smaller than the cross-sectional area of the head portion 1421, and the cross-sectional area of the connecting portion 1422 may be smaller than the area of the second port 144, where the shape of the second port 144 may be square, so as to ensure that the connecting portion 1422 may pass through the second port 144, and an overflow gap 1441 may be formed between the head portion 1421 and the second port 144 when the head portion 1421 is positioned at the second port 144, so that the first pipeline 130 maintains a conductive state when the valve element 142 is positioned at the second port 144. The outer wall of the connection portion 1422 may be extended with a cross rib, the cross-sectional area of the connection portion 1422 may be larger than the area of the second port 144, and the second port 144 may be circular, or other shapes. When the valve core 142 rises along with the rising of the liquid level in the valve cavity 145, the head portion 1421 can completely block the first port 143, and when the valve core 142 falls along with the falling of the liquid level in the valve cavity 145, the cross rib of the connecting portion 1422 can abut against the positioning portion 1411, and water can flow into the heating water tank 120 from a gap formed between the cross rib and the second port 144.

In one embodiment of the present utility model, referring again to fig. 2 and 3 in combination, the area of the first port 143 may be smaller than the area of the second port 144. So configured, the first port 143 can be easily blocked when the valve element 142 is moved to the first position, and the second port 144 can be prevented from being blocked when the valve element 142 is positioned at the second port 144 as the liquid level in the valve cavity 145 decreases to the valve element 142, thereby ensuring that the first pipeline 130 can be in a conductive state.
