Problems solved by technology

[0002] For washable electric kettles or other washable liquid heaters, it is required to have good sealing and no water leakage; however, in a closed chamber with heating elements, when the operating temperature of the heating elements rises, air pressure will be generated. The air pressure will increase as the temperature rises, and the air pressure increase in the airtight heating cavity will cause certain dangers to the machine.

Embodiment 1

[0021] refer to figure 1 , figure 2 , a liquid heater, comprising a body provided with an upper coupler and a base provided with a lower coupler, the body and the base are connected through an upper and a lower coupler, and the body includes a The container 1 and the bottom cover 7 that is sealingly connected on the outside of the bottom of the container 1, the upper coupler is connected on the bottom cover 7 and the connection between the two is sealed so that the container 1 and the A closed cavity 15 is formed between the bottom covers 7 , an electric heating assembly is arranged at the bottom of the container 1 , and a pressure relief valve device 13 is arranged on the bottom cover 7 in a sealed manner. Since the airtight chamber 15 is airtight, when the electric heating components in the airtight chamber 15 work, the gas in the airtight chamber 15 will expand to generate air pressure. When the air pressure in the airtight chamber 15 exceeds the safe air pressure, the pr...

Embodiment 2

[0034] refer to image 3 , Figure 4 , The difference between this embodiment and Embodiment 1 is that the container 1 in this embodiment is a container with a pot body structure. The rest of the structures and functions are the same as those in Embodiment 1.

Embodiment 3

[0036] see Figure 6 The difference between this embodiment and Embodiment 1 is that the pressure relief valve device 13 is a silicone pressure relief device, and an air pressure passage 17 is provided between the pressure relief valve device 13 and the bottom cover. The heating element 3 works to generate air pressure, and the steam pressure leaks outward along the air pressure channel 17, pushing the edge 131 of the pressure relief valve device away, and the air pressure is discharged into the air; since the material of the pressure relief valve device is silica gel, the silica gel has elasticity, when the air pressure After the release, the edge 131 of the pressure relief valve device returns to the original state, the air pressure channel 17 is sealed, and the sealing chamber 15 returns to the sealed state. The rest of the structures and functions are the same as those in Embodiment 1.

Abstract

The invention discloses a liquid heater. The liquid heater comprises a body which is provided with an upper coupler and a base which is provided with a lower coupler, wherein the body and the base are connected through the upper coupler and the lower coupler; the body comprises a container which forms a liquid accommodation cavity and a bottom cover which is hermetically connected to the outer side of the bottom of the container; the upper coupler is connected to the bottom cover, and the joint of the upper coupler and the bottom cover is sealed so that a closed cavity is formed between the container and the bottom cover; the bottom of the container is provided with an electric heating component; and a pressure relief valve device is hermetically arranged on the bottom cover. The closed cavity is closed, so when the electric heating component in the closed cavity works, gas in the closed cavity can swell to produce atmospheric pressure; and when the atmospheric pressure in the closed cavity exceeds safe pressure, the pressure relief valve device discharges pressure for the closed cavity. The invention has the advantages that the liquid heater can be safely and reliably used, is practical and can be accepted by users easily.

Description

technical field [0001] The invention relates to a small household appliance, in particular to a liquid heater. Background technique [0002] For washable electric kettles or other washable liquid heaters, it is required to have good sealing and no water leakage; however, in a closed chamber with heating elements, when the working temperature of the heating elements rises, air pressure will be generated. And this air pressure can increase along with the rising of temperature, and the raising of the air pressure of airtight heating cavity can cause certain danger to machine. Contents of the invention [0003] The object of the present invention is to provide a liquid heater which is safe and reliable in use, and has a simple and practical structure. [0004] For achieving the purpose of the invention, the technical scheme adopted by the present invention is: [0005] A liquid heater, comprising a body provided with an upper coupler and a base provided with a lower coupler,...
