DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. 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.

[0026] like Figures 1 to 5 As shown, the utility model claims protection for an upper cover structure of a liquid heating device, which is applied to a liquid heating device with an all-glass inner pot body. The bottom of the all-glass inner pot body is completely sealed, and the liquid in the all-glass inner pot body is extracted and used through this upper cover structure. Specifically, the upper cover structure includes a cover body 1, on which an infusion tube 2 and an automatic water-stopping component 3 are provided. One end of the infusion tube 2 is connected to the water inlet pipe 13, and the other end of the infusion tube 2 is connected to the automatic water-stopping component 3; when the upper cover structure is installed on the liquid heating device, the water inlet pipe 13 is inserted into the all-glass inner pot body; the water inlet pipe 13 can be a silicone tube or a metal tube, and the material is not limited here; the bottom cover 101 is provided with a pipe set 12, and the water inlet pipe 13 is detachably plugged and fixed on the pipe set 12, so as to be easily replaced or disassembled for cleaning.

[0027] The automatic water-stop component 3 forms a chamber 301, and the infusion tube 2 is connected to the chamber 301. The chamber 301 has a flow port 302. A blocking piece is movably provided in the flow port 302, and the head of the blocking piece is located above the flow port 302, and the head size of the blocking piece is larger than the aperture size of the flow port 302; the head size of the blocking piece mentioned here being larger than the aperture size of the flow port 302 means that the coverage area of ​​the cross-sectional area of ​​the head of the blocking piece is larger than the aperture size of the flow port 302, so that the flow port 30 can be blocked; the blocking piece is connected to an elastic piece 4, and the elastic piece 4 has a downward force on the blocking piece, so that the head of the blocking piece is pressed against the flow port 302 to seal the flow port 302.

[0028] Specifically, in this embodiment, Figure 4 As shown, the plugging member includes a rod 9 and a sealing ring 10 connected to the rod 9, that is, the sealing ring 10 serves as the head of the plugging member, and the outer diameter of the sealing ring 10 is larger than the aperture size of the flow port 302. The rod 9 is connected to the bottom of the base plate 11. The elastic member 4 is a spring that is sleeved on the rod 9. The lower end of the spring is connected to the base plate 11 and the lower end of the spring is connected to the bottom cover 101 below the flow port 302. During assembly, the spring is compressed and has a certain amount of elastic potential energy. There is potential energy for expansion, so the lower end of the spring pushes downward on the base plate 11, thereby making the sealing ring 10 tightly attached to the top of the flow port 302, thereby sealing the flow port 302. When an external force pushes the rod 9 upward, that is, when a gap is formed between the sealing ring 10 and the flow port 302, water entering the chamber 301 will flow downward through this gap.

[0029] When the liquid in the all-glass inner pot body is heated, steam will be generated. If it is not discharged in time, there will be a risk of explosion due to excessive pressure. In this structure, the lower surface of the cover body 1 corresponds to the all-glass inner pot body, so a steam release hole 5 is provided on the outer surface of the cover body 1, and a steam inlet hole 6 is provided on the lower surface of the cover body 1. The steam inlet hole 6 is connected to the steam release hole 5, so that the steam generated during heating is discharged to the outside through the steam inlet hole 6 and the steam release hole 5.

[0030] The cover body 1 includes a bottom cover 101 and a surface cover 102. A sealed rubber ring 14 is provided under the bottom cover 101. The provision of the sealed rubber ring 14 helps to enhance the sealing between the cover body 1 and the all-glass inner pot body; the bottom cover 101 and the surface cover 102 can be fixed by snapping or screwing. The bottom cover 101 and the surface cover 102 enclose a cavity, and the infusion tube 2 is located in the cavity; the automatic water stop component 3 is fixed to the bottom cover 101 and protrudes downward from the lower bottom surface of the bottom cover 101; a steam guide 7 is provided in the cavity, and the lower end of the steam guide 7 is aligned with the steam inlet hole 6 is connected, the upper end of the steam guide 7 is connected with the steam release hole 5, the steam enters the steam guide 7 from the steam inlet hole 6, and is finally discharged from the steam release hole 5, that is, the steam guide 7 is a hollow structure with openings at the top and bottom, the steam enters from the steam inlet hole 6 to the opening below the steam guide 7, passes through the hollow part of the steam guide 7 and finally exits from the opening above the steam guide 7; the steam guide 7 has a guiding effect on the steam and also limits the flow space of the steam to prevent the steam from diffusing in the cavity to form water vapor; Figure 5 It can be seen that the steam guide 7 is in a trapezoidal shape with a small top and a large bottom, so that the steam entering the steam guide 7 can be gathered and then discharged.

[0031] The steam guide 7 includes a protruding head 701 at the top. When the surface cover 102 and the bottom cover 101 are assembled, the protruding head 701 is embedded in the steam release hole 5, which fixes the top end of the steam guide 7 to the surface cover 102, thereby enhancing the fixing effect of the steam guide 7 and making the structure compact.

[0032] The cover 102 is provided with a handle 8. When the full glass inner pot body also needs to be filled with liquid, the upper cover structure needs to be removed as a whole, so the operator can hold the handle 8 to take it out; concave arc surfaces 1021 are provided on both sides of the handle 8. The concave arc surfaces 1021 are opened on the cover 102. Figure 1 It can also be seen intuitively that the closer the part of the concave arc surface 1021 is to the handle 8, the deeper it is, so as to increase the contact area on both sides of the handle 8, that is, it helps to increase the side area of ​​the handle 8, making it easier for people to grasp.

[0033] The bottom cover 101 includes an assembly cylinder 1011, and the rod body 9 is located in the middle of the assembly cylinder 1011, and the axis of the rod body 9 coincides with the axis of the assembly cylinder 1011; a socket is provided in the body of the liquid heating device at a position corresponding to the assembly cylinder 1011, and a push rod is provided in the middle of the socket. When the assembly cylinder 1011 is inserted into the socket, the push rod will lift the rod body 9, thereby creating a gap between the sealing ring 10 and the flow port 302, that is, the chamber 301 and the body of the liquid heating device are water-connected, so that the water entering the chamber 301 can flow into the body of the liquid heating device through the gap.

[0034] like Figure 4As shown, the spring serving as the elastic member 4 is a conical spring. In the same installation space, the conical spring of the same volume can withstand greater pressure than an ordinary compression spring, and accordingly can store more energy. It can withstand greater pressure under the same deformation, which can increase its service life.

[0035] The application principle of this upper cover structure is: the upper cover structure is applied to a liquid heating device with an all-glass inner pot body, and the bottom of the all-glass inner pot body is completely sealed, so the liquid in the all-glass inner pot body is extracted by extraction, and this upper cover structure is used to cooperate with the extraction of liquid from the all-glass inner pot body. When the upper cover structure is installed on the liquid heating device, the upper cover structure is located above the all-glass inner pot body, and the water inlet pipe 13 is inserted into the all-glass inner pot body; and when the upper cover structure is installed on the body of the liquid heating device, the body of the liquid heating device has a push rod to lift the rod body 9, so that the chamber 301 is in water communication with the body of the liquid heating device; the body of the liquid heating device has a water pump, and the water pump is located in the water channel connected to the chamber 301, so the operation of the water pump will extract the liquid in the all-glass inner pot body, so that the liquid passes through the water inlet pipe 13. Tube 13, infusion tube 2, chamber 301 and finally flow into the heating component in the body of the liquid heating device for heating; and when the liquid in the all-glass inner pot body is used up and needs to be replenished, it is necessary to lift up the upper cover structure, and when the upper cover structure is lifted up, the rod body 9 is no longer lifted by the top rod in the body of the liquid heating device, so the rod body 9 will be pressed down by the action of the spring, that is, the sealing ring 10 re-presses and seals the flow port 302 to prevent the liquid in the infusion tube 2 and the chamber 301 from dripping, that is, the automatic water-stopping component 3 achieves the effect of automatic sealing and water-stopping.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
