According to the liquid heater of this application, through setting up first steam outlet 81 and second steam outlet 82, can be under the prerequisite of guaranteeing the steam emission volume of predetermineeing, the size of every steam outlet 80 of minimize avoids setting up too big and leads to liquid to spill over from the steam outlet easily. In addition, the relatively large number of steam outlets 80 are provided on the lower cover 22, so that the steam at each position in the container body 10 can be distributed to achieve the purpose of timely discharging.
In an embodiment, the lid assembly 20 is further provided with a steam discharge port 221, the liquid heater further includes a handle part 110 and a steam discharge channel 120 provided in the handle part 110, the steam discharge port 221 communicates the second receiving chamber 40 and an upper end of the steam discharge channel 120, and a lower end of the steam discharge channel 120 extends to a bottom of the liquid heater.
According to the liquid heater of the present application, by further providing the steam discharge port 221 on the cap assembly 20, most of the steam entering the second accommodating chamber 40 can enter the bottom of the liquid heater through the steam discharge channel 120 via the steam discharge port 221 and then be discharged out of the liquid heater, only a small portion of the steam can be condensed in the cap assembly 20, and since the whole flow path of the steam is not easily directly contacted by a user, the risk of scalding during use can be reduced.
In an embodiment, the cap assembly 20 further has a pouring gate 222, the pouring gate 222 is connected to the liquid outlet 50, and when the liquid outlet 50 is opened, water can be poured through the pouring gate 222, and the cap assembly 20 is symmetrical about a line connecting the pouring gate 222 and the handle portion 110. The exhaust lines 90 are at least two and are symmetrically arranged about the connecting line. The first steam outlets 81 are at least two and are symmetrically arranged about the connecting line, and are respectively disposed near the edge of the lower cover 22 and connected to the corresponding inlet pipes 91. The inlet of each exhaust duct 90 communicates with the respective first steam outlet 81 and the outlet communicates with the second containing chamber 40.
In an embodiment, each exhaust duct 90 is a U-shaped duct, the bottom of the U-shaped duct is closer to the connecting line relative to the opening, and the bottom of the U-shaped duct is disposed toward the handle portion 110. The second steam outlets 82 are at least two and are symmetrically arranged about the connecting line, and are disposed closer to the connecting line with respect to the first steam outlets 81, and are connected to the corresponding third seal segment 933.
According to the liquid heater of this application, through setting up exhaust pipe 90 to a plurality ofly and about the line symmetrical arrangement, every exhaust pipe 90 is close to the edge setting of lower cover 22 respectively, set up exhaust pipe 90 to the U-shaped, and exhaust pipe 90's entry sets up in the border department of lower cover 22, like this exhaust pipe 90's entry and export can be located exhaust pipe 90 with one side, when liquid heater is in the state of empting, exhaust pipe 90 who is located the liquid level below is sealed, in order to avoid high temperature liquid to leak, exhaust pipe 90's entry that is located the liquid level top is located the border of the highest point of lid subassembly 20, be convenient for discharge steam pressure in the container body 10 inner chamber, can be better prevent steam pressure from spouting exhaust pipe 90 with water and avoid container body 10 inner chamber too big and dangerous phenomenon such as explosion.
An example of the structure of the exhaust line is shown in fig. 5. In the example shown in fig. 5, there are two exhaust pipes 90, each exhaust pipe 90 is a U-shaped pipe, and an inlet (i.e., an air inlet end) and an outlet (i.e., an air outlet end) of the exhaust pipe 90 are respectively located at the edge position of the lower cover 22 and on the same side of the connecting line.
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.
