[0027] Through the above-mentioned setting, the air outlet needle 42 is slidingly sealed and installed in the installation slide, realizing the sliding connection between the air outlet needle 42 and the sealing connector 3, eliminating the leather tube connection method of the air outlet needle, avoiding the problem of loose connection and leather tube folding caused by the floating of the leather tube at the air outlet needle, and improving the sealing effect.

[0028] In the gas outlet valve connection structure of a lighter of this embodiment, the sealing connector 3 includes a connecting upper cover 31, a connecting lower cover 32 and a connecting head 33. The connecting upper cover 31 is fixedly mounted on the mounting shell 1; the upper end of the connecting upper cover 31 has an outlet pipe 311, and the lower end of the connecting upper cover 31 has a positioning groove 312; the connecting lower cover 32 is matched and embedded in the positioning groove 312, and the lower end of the connecting lower cover 32 has a connecting pipe 321. There is a gap between the connecting upper cover 31 and the connecting lower cover 32 to connect The air outlet pipe 311 and the connecting pipe 321; the connecting head 33 is fixedly installed on the mounting shell 1; the connecting head 33 has a connecting ring groove 331 for the connecting pipe 321 to fit in, and the bottom wall of the connecting ring groove 331 is provided with a mounting hole 332 for the air outlet needle 42 to pass through.

[0029] Through the above arrangement, the sealed connector 3 includes the connecting upper cover 31, the connecting lower cover 32 and the connecting head 33, which are simple to manufacture, low in manufacturing cost and easy to assemble. Optionally, the space enclosed by the connecting pipe 321, the sealing ring 34 and the mounting hole 332 constitutes an installation slideway.

[0030] In a lighter air outlet valve connection structure of this embodiment, a mounting groove 12 is formed at the upper end of the mounting shell 1, a connector 33 is fixedly embedded in the mounting groove 12, and the valve body 41 of the air outlet valve 4 is located below the mounting groove 12; the upper connecting cover 31 is fixed to the upper end of the mounting shell 1 by a fastener 13. In this arrangement, the upper connecting cover 31 is fixed to the mounting shell 1 by the fastener 13, the lower connecting cover 32 is located below the upper connecting cover 31, and the connector 33 is located below the lower connecting cover 32. The upper connecting cover 31 and the lower connecting cover 32 collide with the connector 33, and the connector 33 collide with the mounting shell 1, so that the upper connecting cover 31 presses the lower connecting cover 32 downward, the lower connecting cover 32 presses the connector 33 downward, and the connector 33 presses the mounting shell 1 downward, so that the upper connecting cover 31, the lower connecting cover 32, the connector 33 and the mounting shell 1 form a stable assembly structure with good installation stability.

[0031] In the outlet valve connection structure of a lighter of this embodiment, the connector 33 is a zinc alloy connector 33. The zinc alloy material has good structural strength, is not easy to deform, ensures sealing effect, and has a long service life.

[0032] In the lighter outlet valve connection structure of this embodiment, the connection cover 31 is made of zinc alloy. This material offers high structural strength, resists deformation, ensures a good seal, and prolongs service life. Specifically, the connection cover 31 is a zinc alloy connection tee.

[0033] In the lighter outlet valve connection structure of this embodiment, there are multiple vaporizers 22 and multiple outlet pipes 311 connected to the upper cover 31, and the multiple vaporizers 22 are connected to the multiple outlet pipes 311 in a one-to-one correspondence. This arrangement allows multiple vaporizers 22 to be installed simultaneously, improving the use effect, simplifying the structure, and facilitating assembly.

[0034] In the outlet valve connection structure of a lighter according to this embodiment, a portion of the outlet pipes 311 are connected to the vaporizers 22 in a one-to-one correspondence via the conductive hoses 5, while another portion of the vaporizers 22 are plugged into the outlet pipes 311.

The nitrile leather pad 6 is a tubular structure, and the vaporizer 22 is inserted into the nitrile leather pad 6. This arrangement improves the sealing effect and installation stability.

[0036] In the gas outlet valve connection structure of a lighter of this embodiment, the connection lower cover 32 is a nitrile seal, which improves the sealing effect.

[0037] In the gas outlet valve connection structure of a lighter of this embodiment, the sealing ring 34 is a NBR O-ring, which improves the sealing effect.

[0038] In the air outlet valve connection structure of a lighter of this embodiment, the mounting bracket 2 is a zinc alloy bracket, which has high structural strength, is not easily deformed, and has a long service life.

[0039] In the air outlet valve connection structure of a lighter of the present embodiment, a NBR O-ring is sleeved on the air outlet needle 42, and the NBR O-ring is fixed downwardly by a zinc alloy connector 33, and the NBR O-ring is supported upwardly by a NBR gasket. When the lighter button is pressed, the air outlet needle 42 floats up and down, and only floats up and down in a straight line within the air outlet needle head and the NBR O-ring, effectively reducing the problem of loosening and folding caused by the floating leather tube at the air outlet needle, and solving the problem of poor sealing caused by multiple movements and deformations of the air outlet needle when the leather tube is used for connection.
