[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 a cannula. Therefore, there is no need to open an interface at the bottom of the full glass inner liner 201. The sealing is good and there is no interface penetration problem. The full glass inner liner 201 is integrally formed with a handle position 2011 at the upper end and a narrowing portion 2012 at the lower end. The handle position 2011 is helpful for picking up the entire heating kettle body 2. A heating plate 202 for heating is connected to the bottom of the narrowed portion 2012. The heating plate 202 is tightly attached to the bottom of the narrowed portion 2012. After being powered on and heated, it heats the liquid in the all-glass liner 201. The heating plate 202 is covered with a heat insulation cover 203, so that the heat generated by the heating plate 202 is surrounded in the heat insulation cover 203, which not only reduces the dissipation of heat, but also helps to concentrate the heat to heat the all-glass liner 201, improve the heating effect, and prevent the heat from being dissipated outward to cause damage to other components.

[0039] The upper end of the heat shield 203 is fixedly connected to the narrowing portion 2012. The specific fixing structure is that the lower end of the narrowing portion 2012 has a circular clamping edge 20121 protruding outwards, and the circular clamping edge 20121 is provided with a semicircular clamping plate pair 205 that can be opened and closed. The semicircular clamping plate pair 205 is fixed in the narrowing portion 2012 and is located above the circular clamping edge 20121; Fig.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 screwing in bolts at the joints; the opening diameter formed by the combination 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 combined 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 first threaded connecting columns 2031 in position 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 full glass liner 201 are fixed; in actual design, a connecting foot tube is provided under the heating plate 202, and the connecting foot 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 member can be provided between the connecting foot tube and the heat insulation cover 203 in the heating plate 202. The ceramic heat insulation member can be a hollow ceramic column, which is located between the connecting foot tube and the heat insulation cover 203. Screws are driven into the heat insulation cover 203 from bottom to top, pass through the ceramic column and are connected to the connecting foot tube, so that the connecting foot tube and the heat insulation cover 203 are fixed with a certain isolation to reduce heat conduction.

[0040] It 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 the narrowing part 2012, the heating plate 202 and the heat insulation cover 203 are completely covered 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, and the reserved opening 2041 facilitates the use of the coupler 206 corresponding to 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 also formed with an inclined surface 2042 which is gradually recessed upward toward the center, so that the coupler 206 is higher than the surrounding surface of the base 204, that is, the lower end of the coupler 206 is higher than the surrounding surface of the base 204, and when the heating kettle body 2 is placed on a desktop, a certain height distance is maintained between the coupler 206 and the desktop, and moisture on the desktop will not contact the coupler 206, thereby avoiding the risk of short circuit due to water on the coupler 206 in later work.

[0042] The main body 1 is movably covered with a movable cover 3, and the movable cover 3 is located above the full glass liner 201; the movable cover 3 is provided with a water-connected liquid extraction tube 301, a liquid infusion tube 302 and an opening and closing valve 306, the liquid extraction tube 301 is inserted into and assembled into the upper opening of the full glass liner 201, and the opening and closing valve 306 is provided with a blocking member 4 for controlling the passage; a lifting member 5 is provided at a position corresponding to the opening and closing valve 306 on the main body 1; the main body 1 is provided with a lifting member 5 for controlling the opening of the opening and closing valve 306; when the movable cover 3 is covered on the main body 1 so that the lifting member 5 is connected with the opening and closing valve 306, the opening and closing valve 306 is opened to connect the movable cover 3 with the water channel of the main body 1; when the movable cover 3 is pulled away from the main body 1 so that the lifting member 5 is separated from the opening and closing valve 306, the opening and closing valve 306 is closed to disconnect the movable cover 3 from the water channel of the main body 1.

[0043] Specifically, the on-off valve 306 has a chamber 3061, the infusion tube 302 is connected to the chamber 3061, a water outlet channel 3062 is formed in the middle of the chamber 3061, and the blocking member 4 is located in the water outlet channel 3062; the blocking member 4 includes a rod body 401 and a first sealing ring 402 connected to the rod body 401, the diameter of the rod body 401 is smaller than the water outlet channel 3062, so that a flow gap is formed between the outer wall of the rod body 401 and the inner wall of the water outlet channel 3062; the rod body 401 is movably arranged in the water outlet channel 3062, and the diameter of the first sealing ring 402 is larger than the aperture of the water outlet channel 3062, so that When the rod body 401 is pressed down, the first sealing ring 402 will be pressed against the top of the water outlet channel 3062 to seal, so that the liquid in the chamber 3061 cannot flow into the flow gap; the blocking member 4 also includes a bottom plate 403 connected to the bottom of the rod body 401, and the diameter of the bottom plate 403 is larger than the aperture of the water outlet channel 3062, which can prevent the bottom plate 403 from being pressed excessively and embedded in the water outlet channel 3062; an elastic component 6 is provided on the rod body 401, and the elastic component 6 has a thrust on the bottom plate 403, so that the first sealing ring 402 can be pressed against the water outlet channel 3062 to seal; in this embodiment, the elastic component 6 is a spring, which is Figure 8 It can be seen that the spring is mounted on the rod body 401, the lower end of the spring is connected to the bottom plate 403, and 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 downward 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. At this time, the opening and closing valve 306 can achieve the effect of water sealing to prevent the residual liquid in the infusion tube 302 and the chamber 3061 from flowing down and causing dripping.

[0045] The movable cover body 3 is provided with a nozzle tube 303 for alignment and assembly, the blocking member 4 is located in the middle of the nozzle tube 303, and the lower end of the nozzle tube 303 is narrowed inwardly; the main body 1 is provided with an insertion position 101, the insertion position 101 corresponds to the position of the nozzle tube 303, and the narrowing setting of the lower end of the nozzle tube 303 is to facilitate smooth insertion into the insertion position 101, and the lifting member 5 is located in the middle of the insertion position 101, corresponding to the position of the rod body 401; when the movable cover body 3 is assembled to the main body 1, the lifting member 5 lifts the rod body 401, that is, the first sealing ring 402 is aligned with the water outlet The channel 3062 is separated, so that the liquid in the chamber 3061 can flow down to the insertion position 101 from the flow gap between the outer wall of the rod body 401 and the inner wall of the water outlet channel 3062, that is, the liquid extraction tube 301, the liquid infusion tube 302, the opening and closing valve 306 and the main body 1 are connected in water, which helps to extract the liquid in the full glass liner 201 into the main body 1 for heating and discharge; in the actual design, the inner wall of the insertion position 101 has a sealing ring to increase the sealing between the inner wall of the insertion position 101 and the outer wall of the nozzle tube 303 to avoid air leakage.

[0046] It also includes a water pump; as one embodiment, the water pump is connected with the infusion tube 302 and is arranged on the movable cover body 3, that is, the water pump is designed in the movable cover body 3, and when the water pump is working, the liquid in the full glass liner 201 is drawn upward through the liquid extraction tube 301 and enters the infusion tube 302, flows through the opening and closing valve 306 and the insertion position 101 and flows into the main body 1; or, the water pump is connected with the insertion position 101 and is arranged on the main body 1, that is, the water pump is designed in the main body 1, and is connected to the insertion position 101 through a pipeline, and after the water pump is working, the liquid in the full glass liner 201 flows from the liquid extraction tube 301, the infusion tube 302, the opening and closing valve 306, and the insertion position 101 into the main body 1 in sequence.

The high thermal conductivity medium is a thermally conductive metal paint, which can make up for the phenomenon that the surface of the heating plate 202 is not sufficiently in contact with the lower surface of the narrowing portion 2012 due to the uneven surface of the heating plate 202. Adding thermally conductive metal paint helps to enhance the thermal conductivity effect.

[0051] The all-glass upper pumping liquid heating device of the present invention comprises three major parts: a main body 1, a heating kettle body 2 and a movable cover body 3. When the movable cover body 3 is installed on the main body 1, the pumping tube 301 is inserted into the all-glass inner tank 201 for pumping water. The lifting member 5 of the main body 1 lifts the blocking member 4 of the opening and closing valve 306 and moves it upward, so that the opening and closing valve 306 is in an open state. At this time, the movable cover body 3 is connected with the main body 1 by water, so that the water in the all-glass inner tank 201 can be pumped out. This structure does not need to be considered Regarding the sealing problem between the liquid extraction tube 301 and the all-glass inner liner 201, the liquid extraction tube 301 is directly inserted from the upper opening of the all-glass inner liner 201 for extraction, so the all-glass inner liner 201 can be designed to be bottom-closed and have good sealing performance; when the movable cover body 3 is pulled up, the blocking member 4 will block the opening and closing valve 306 to achieve water sealing, and the water extraction waterway is disconnected. At this time, the residual liquid in the chamber 3061 in the movable cover body 3 and the infusion tube 302 will not flow down to cause dripping, thereby avoiding dirt.
