The liquid heater of the present application, due to the structure, will fall in a certain direction when pouring, and generally has two pouring states, which can fall in the direction shown in fig. 6, and can also fall in the mirror image direction relative to fig. 6.

An example of a pouring state of the liquid heater is shown in fig. 6. In the example shown in fig. 6, on the premise of normal filling amount in the inner cavity of the container body 10, when the liquid heater is toppled, the pouring seal 100 of the B group located below rolls to the blocking position, and at this time, the first steam outlet 81 and the second steam outlet 82 of the B group are both generally below the liquid level, and since the pouring seal 100 is in the blocking position, the liquid in the inner cavity of the container body 10 cannot overflow. At this time, the U-shaped exhaust line 90 of group B is in a sealed state. At the same time, the dumping seal 100 of group a is not in the blocking position, the U-shaped vent pipe 90 is in the conducting state, and the first steam outlet 81 of group a is at the highest position of the lower cover 22, generally above the liquid level in the inner cavity of the container body 10, when there is steam pressure inside the liquid heater, the steam can enter the U-shaped vent pipe 90 of group a through the first steam outlet 81 and be discharged from the outlet 941. In addition, after the air pressure in the inner cavity of the container body 10 is released, the liquid in the inner cavity may enter the exhaust pipeline 90 from the second steam outlet 82, but since the outlet 941 is also at the highest position, which is higher than the liquid level in the inner cavity of the container body 10, the liquid will not overflow from the outlet 941. Therefore, the exhaust line 90 of group a is in an open state, so that the air pressure in the cavity of the container body 10 can be released, and the liquid in the cavity of the container body 10 can be prevented from overflowing.

In conclusion, according to the liquid heater of this application, can in time discharge the comdenstion water in the second holds chamber 40 through backward flow mouth 60, avoid long-term storage to lead to bacterial growing and then guaranteed the health of drinking water.

Although the embodiments of the present application have been described in detail above, those skilled in the art may make various modifications and alterations to the embodiments of the present application without departing from the spirit and scope of the present application. It will be understood that those skilled in the art will recognize modifications and variations as falling within the spirit and scope of the embodiments of the application as defined by the claims.
