Compared with the first embodiment, the present embodiment can utilize the inner space of the upper and lower couplers to provide the liquid discharge channel, so that the liquid discharge channel can be prevented from being provided at other positions of the kettle body 20 and the stand 10, and the space utilization can be improved. Specifically, when the upper and lower couplers are coupled, the drain pipe assembly and the pumping pipe assembly can be in plug-in fit to realize outward water outflow of the kettle body 20.

Specifically, the drain pipe assembly includes the drain pipe, the suction pipe assembly includes drinking-water pipe and suction pump, when last coupler 201 and lower coupler 101 grafting cooperation, the drinking-water pipe with the drain pipe grafting cooperation, under the effect of suction pump, can realize that the liquid in the kettle body 20 is discharged through drain pipe and drinking-water pipe.

Further, a one-way valve is arranged between the drain pipe and the water suction pipe, and is in one-way conduction along the direction from the drain pipe to the water suction pipe and used for controlling the conduction or the disconnection of the drain pipe and the water suction pipe. Under the condition that the drain pipe and the water suction pipe are communicated, the liquid in the kettle body 20 can be pumped out by starting the water suction pump, so that the manual water pouring operation of a user is omitted.

The structure of the check valve is not particularly limited, and any one of the prior art types of check valves can be used. For example, to simplify the structure, the check valve is a valve plate, for example, a water passing slit is arranged on the valve plate, and the water passing slit can be opened or closed by utilizing the change of the pressure on two sides of the valve plate. Under the natural state, the water slot is closed, when the water suction pump is started, the suction force can be generated on one side of the water suction pump so as to promote the water slot to be opened, and at the moment, the drain pipe is communicated with the water suction pipe, so that the liquid discharging operation can be performed.

In addition to the first and second embodiments, the liquid heater of the present application has the following structure.

The top of the stand 10 is provided with a second placing cavity 103 in a downward concave manner, and the kettle body 20 is arranged in the second placing cavity 103 in a removable manner; the stand 10 comprises a stand side part connected with the second placing cavity 103 and the first placing cavity 102, a first mounting cavity 104 is arranged in the stand side part, and at least one of a circuit board for controlling heating of the kettle body 20 and an air pump for supplying air into the kettle body 20 is arranged in the first mounting cavity 104; a second installation cavity 105 is arranged in the bottom of the stand 10, and the second installation cavity 105 is provided with a pressure sensor for sensing the weight change of the whole machine.

As shown in fig. 1 and 4, by providing the first placing cavity 102 and the second placing cavity 103 in the stand 10, a placing space is provided for the tea dispenser 30 and the kettle body 20, and by providing the first mounting cavity 104 and the second mounting cavity 105, a layout space is provided for electric elements and the like, and the internal and external spaces of the stand 10 are fully utilized to compactly arrange the structures, so that the compactness and the miniaturization of the whole machine are promoted.

It will be appreciated that the second placement chamber 103 may be omitted, and the top of the stand 10 may be configured as a flat surface for placement of the kettle body 20. The first installation cavity 104 can also be used for arranging a water suction pump so as to pump water to the kettle body 20. The circuit board is not limited to being disposed in the first mounting chamber 104, but may be disposed in the second mounting chamber 105. Further, the second mounting chamber 105 may also be used as a waste water box (in which case no electrical components are provided in the second mounting chamber 105) to facilitate storing waste water.

Because the electric heating kettle body in the prior art is characterized in that a large amount of gas is formed in the cover body by boiling water in the heating kettle body, and the water in the cover body is moved upwards to be sprayed in the tea basket assembly through pressure, as described in patent application CN201010550290.9, the technical scheme has the function of not controlling the tea making temperature, can only be used for making tea by boiling water, and cannot adapt to the selection of different functions, such as black tea, green tea, ginger tea, scented tea, coffee and the like, and different processing temperatures are needed. Another prior art is as in CN108814294a brewing apparatus, and by adopting the technical scheme of the spiral, water in the container 1 is conveyed into the tea basket, and by adopting the technical scheme, the screw structure is complex, the occupied space of the screw in the kettle body is large, the capacity of the container 1 for containing liquid is reduced, and the experience effect is poor.

Based on the technical problem, the liquid heater of this application is equipped with tea strainer assembly 21 in the kettle body 20, tea strainer assembly 21 includes tea strainer 22, locates the cover body 23 of tea strainer 22 below and connect tea strainer 22 with the honeycomb duct 24 of cover body 23, honeycomb duct 24 upper end stretches into in the tea strainer 22, honeycomb duct 24 lower extreme stretches into in the cover body 23, the cover body 23 be equipped with the intercommunicating pore 231 of the inside intercommunication of the kettle body 20, liquid in the kettle body 20 passes through intercommunicating pore 231 gets into the cover body 23 and passes through honeycomb duct 24 gets into tea strainer 22.

Wherein, the cover body 23 cooperates with the bottom wall of the kettle body 20 to form a steam cavity, when water in the kettle body 20 enters the cover body 23 through the communication hole 231, the pressure of the steam cavity is increased by external power to push the water in the cover body 23 to enter the guide pipe 24 from the lower end of the guide pipe 24, and then move upwards and enter the tea strainer 22 through the upper end of the guide pipe 24. It will be appreciated that the water in the kettle body 20 can be heated to any temperature and then enter the tea strainer 22 to brew the material in the tea strainer 22, so that the brewing of various beverages can be satisfied. Preferably, a temperature sensor 202 is provided at the bottom of the kettle body 20 to detect the temperature of the liquid in the kettle body 20 to precisely control the desired brewing temperature.

As shown in fig. 4 and 6, the cover 23 is covered on the bottom wall of the kettle body 20, and the lower end of the flow guide pipe 24 is higher than the bottom wall of the kettle body 20 to form a water inlet gap 241 with the bottom wall of the kettle body 20, so that when water in the kettle body 20 enters the cover 23 through the communication hole 231, the water can enter the lower end of the flow guide pipe 24 through the water inlet gap 241.

As shown in fig. 8 and 9, the tea drain assembly 21 may be formed as a unitary structure that is placed into the kettle body 20 when brewing is desired and removed to increase the processing space within the kettle body 20 when brewing is not desired.

Further, a sealing plug 242 is arranged at the top of the flow guiding pipe 24, and a plurality of spraying holes 243 are formed in the side wall of the upper end of the flow guiding pipe 24, so that the liquid in the flow guiding pipe 24 sprays the liquid to the tea strainer 22 through the spraying holes 243; a tea net 221 is arranged at the bottom of the tea strainer 22, and the liquid entering the tea strainer 22 through the guide pipe 24 infuses the materials on the tea net 221 and then enters the kettle body 20 through the tea net 221.

In this embodiment, as shown in fig. 7, the plurality of spraying holes 243 are circumferentially arranged along the side wall of the flow guiding tube 24, so that the liquid can be sprayed to the materials on the tea network 221 in all directions, and all the materials can be brewed as much as possible, so as to improve the brewing effect, and the situation that the liquid can only act on a small range of materials directly downwards along the flow guiding tube 24 after flowing out from the top of the flow guiding tube 24 can be avoided. The material on the tea network 221 can be tea, coffee powder, etc. so as to realize multifunctional brewing.
