It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0037] like Figures 1 to 12 As shown, the utility model requests protection for a new type of liquid heating device with water pumping from all glass, including a main body 1, on which a heating kettle body 2 is provided. The heating kettle body 2 is movably placed in the main body 1 for heating, and the heating kettle body 2 can be removed separately for easy addition of liquid or cleaning. The liquid to be heated by the liquid heating device is water, and the liquid heating device is used as a milk mixer.

[0038] The heating kettle body 2 includes a full-glass inner liner 201 for loading liquid. The full-glass inner liner 201 is a closed bottom with an upper opening. The liquid in the full-glass inner liner 201 is extracted by an intubation tube. Therefore, there is no need to open an interface at the bottom of the full-glass inner liner 201, and the sealing is good, and there is no interface penetration problem. Among them, the full-glass inner liner 201 is integrally formed with a handle position 2011 at the upper end and a narrowed portion 2012 at the lower end.

The circular clamping edge 20121 is provided with a retractable semicircular clamping plate pair 205. The semicircular clamping plate pair 205 is fixed in the narrowing portion 2012 and is located above the circular clamping edge 20121. Figure 11 It can be seen that the semicircular clamping plate pair 205 is actually a pair of semicircular clamping plates, which are combined with each other and connected and fixed by measuring and screwing bolts at the joints; the opening diameter formed by the merging of the semicircular clamping plate pair 205 is smaller than the diameter formed by the encirclement of the circular clamping edge 20121, so that the merged semicircular clamping plate pair 205 is limited above the circular clamping edge 20121; a plurality of first threaded connecting columns 2031 are provided on the heat insulation cover 203, and a plurality of first threaded holes 2051 are provided on the semicircular clamping plate pair 205. The first threaded holes 2051 correspond to the positions of the first threaded connecting columns 2031 and are used in conjunction with each other. By passing a screw through the first threaded hole 2051 and connecting to the first threaded connecting column 2031, The heat insulation cover 203 is fixed on the semicircular clamping plate pair 205, that is, the heat insulation cover 203 and the all-glass inner tank 201 are fixed; in actual design, a connecting leg tube is provided under the heating plate 202, and the connecting leg tube has an internal threaded hole. In order to further reduce the heat conduction of the heating plate 202 to the heat insulation cover 203, a ceramic heat insulation piece can be provided between the connecting leg tube and the heat insulation cover 203 in the heating plate 202. The ceramic heat insulation piece can be a hollow ceramic column, which is located between the connecting leg tube and the heat insulation cover 203. The screws are driven into the heat insulation cover 203 from bottom to top, pass through the ceramic column and are connected to the connecting leg tube, so that the connecting leg tube and the heat insulation cover 203 are fixed with a certain isolation to reduce heat conduction.

[0040] The kettle also includes a base 204 for supporting the all-glass kettle body. The base 204 is connected to the bottom of the all-glass kettle body, and completely covers the narrowed portion 2012, the heating plate 202 and the heat insulation cover 203 inside the base 204.

[0041] A coupler 206 is provided below the heat shield 203, and a reserved opening 2041 is provided at the base 204 corresponding to the coupler 206. The reserved opening 2041 facilitates the corresponding use of the coupler 206 with the coupler in the main body 1; the lower end of the coupler 206 is substantially flush with the reserved opening 2041, and the lower surface of the base 204 is further formed with inclined surfaces 2042 which are gradually recessed upwards toward the center, so that the coupler 206 is higher than the surrounding surfaces of the base 204, that is, the lower end of the coupler 206 is higher than the surrounding surfaces of the base 204. When the heating kettle body 2 is placed on a table, a certain height distance is maintained between the coupler 206 and the table, and moisture on the table will not come into contact with the coupler 206, thereby avoiding the risk of short circuit due to water on the coupler 206 during later operation.

Figure 8 It can be seen that the spring is mounted on the rod body 401, and the lower end of the spring is connected to the bottom plate 403. The lower end of the spring is connected to the lower part of the water outlet channel 3062. The spring is in a compressed state and has a certain elastic potential energy. Therefore, the spring has a downward thrust on the bottom plate 403, so that the first sealing ring 402 can be pressed against the water outlet channel 3062 for sealing, so that the residual liquid in the infusion tube 302 and the chamber 3061 will not flow down and cause dripping.

[0044] The purpose of this function is that when liquid needs to be added to the heating kettle body 2, the movable cover body 3 needs to be removed.
