[0002] In the conventional design, the existing thermoelectric flameout protection solenoid valve and thermocouple connection device are usually connected through the pin installed in the solenoid valve body and the end wire plug-in of the thermocouple. This design enables the transmission of current between the thermocouple and the solenoid valve, thereby realizing the control of the switch state of the solenoid valve by the thermocouple, and then controlling the on and off of the gas, achieving the purpose of safety protection.

[0003] CN 203837036 U discloses an energy-saving gas flameout protection solenoid valve. The connection structure of the solenoid valve, i.e., the guide sleeve and the protection sleeve connected to the guide sleeve, is difficult to assemble and disassemble, which increases the difficulty and cost of installation. For this reason, the present application is specially proposed. Summary of the invention

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example 1

[0033] like Figure 1-9 As shown, in this embodiment, a connection structure suitable for a solenoid valve 3 of a gas appliance is disclosed, including:

[0034] A guide sleeve 1 for installation at one end of a solenoid valve 3, wherein a spring sheet 11 is provided on the side of the guide sleeve 1;

[0035] The protective sleeve 2 is used for socket-fitting with the guide sleeve 1. The protective sleeve 2 is provided with a spring buckle 22. When the protective sleeve 2 is inserted into the guide sleeve 1, the spring buckle 22 is located on the inner side of the spring piece 11. After the spring piece 11 is pressed and deformed, the spring buckle 22 is unlocked to make it out of the clamping state of the guide sleeve 1.

[0036] Furthermore, in this embodiment, the guide sleeve 1 is fixedly mounted on one end of the solenoid valve 3, and the protective sleeve 2 is used to connect the thermocouple. Through the connection between the guide sleeve 1 and the protective sleeve 2, the pin 31 of the solenoid valve 3 is connected to the thermocouple signal. The thermocouple can generate a millivolt-level thermoelectric potential in the flame. Under the action of the thermoelectric potential, the solenoid valve 3 is kept in the attracted state, and the gas is in the connected state. Similarly, when the flame of the gas burner is extinguished, the thermoelectric potential of the thermocouple gradually disappears, so that the solenoid valve 3 remains in the closed state, and the gas is disconnected, thereby preventing gas leakage.

[0037] Furthermore, combined with Figure 2 As shown, one end of the guide sleeve 1 is detachably connected to one end of the protective sleeve 2, and the end of the protective sleeve 2 away from the guide sleeve 1 is used to connect a thermocouple.

[0038] Specifically, combined Figure 4-6 As shown, the guide sleeve 1 is provided with an inner plug-in column 14 with a hole, and the pin 31 of the solenoid valve 3 extends through the inner plug-in column 14; the inner plug-in column 14 is used to increase the stability of the pin 31 and prevent it from deforming relative to the guide sleeve 1. The inner diameter of the guide sleeve 1 is adapted to the outer diameter of the protective sleeve 2, so that the protective sleeve 2 can be plugged and matched with the guide sleeve 1. The outer diameter of the inner plug-in column 14 is not greater than the inner diameter of the protective sleeve 2, so that the inner plug-in column 14 can be inserted into the protective sleeve 2.

[0039] Specifically, combined Fig. 9 As shown, the end of the protective sleeve 2 facing the guide sleeve 1 is provided with a notch 21, the spring buckle 22 is located in the notch 21, and the end of the spring buckle 22 facing the guide sleeve 1 is lower than the end of the protective sleeve 2 facing the guide sleeve 1; accordingly, the spring piece 11 is located in the middle position of the side edge of the guide sleeve 1 along the axial direction.

[0040] Specifically, a shoulder 13 is circumferentially provided at one end of the guide sleeve 1 away from the protective sleeve 2. The shoulder 13 is formed by the end edge of the guide sleeve 1 extending radially outward. The solenoid valve 3 includes a flange 32, and the flange 32 has an inner hole formed by shrinking. The outer diameter of the guide sleeve 1 is adapted to the inner hole of the flange 32, and the outer diameter of the shoulder 13 is larger than the inner hole of the flange 32. In this embodiment, a guide groove 23 is provided on the outer wall of the protective sleeve 2, and a guide rib 12 is provided on the inner wall of the guide sleeve 1. The guide sleeve 1 and the protective sleeve 2 are integrally formed by injection molding. In some other embodiments, a guide groove 23 is provided on the inner wall of the guide sleeve 1, and a guide rib 12 is provided on the outer wall of the protective sleeve 2 corresponding to the guide groove 23. The guide sleeve 1 and the protective sleeve 2 are metal parts.

[0041] Combination Figure 1-3 As shown, in other embodiments, a solenoid valve 3 assembly is disclosed, including a solenoid valve 3, a thermocouple and the connection structure described in this embodiment.
