[0018] The technical solution of this utility model will be further described below through specific embodiments.

[0019] Example

[0020] An automatically aligned gas delivery connector includes a male connector 1 and a female connector 2. The male connector 1 is provided with a fixed seat 101, an elastic element 102, a connecting rod 103, and a connecting head 104. The fixed seat 101 is connected to the connecting rod 103 through the elastic element 102. The connecting rod 103 and the connecting head 104 are fixedly connected. The connecting rod 103 and the connecting head 104 are provided with a lower gas passage 105. The connecting head 104 matches the guide cone surface 205 and the sealing cone surface 206 provided on the female connector 2. The guide cone surface 205 and the upper gas passage 204 are connected through the sealing cone surface 206.

[0021] The female connector 2 includes a connecting seat 201, a sealing element 202, and a guide element 203. The connecting seat 201 is provided with an upper air passage 204. The connecting seat 201 at the end of the upper air passage 204 is provided with a guide element 203. The guide element 203 has a guide cone surface 205 on its inner side. The connecting seat 201, which is connected to the end of the upper air passage 204 by the guide cone surface 205, is provided with a sealing element 202. The sealing element 202 has a sealing cone surface 206 on its inner side.

[0022] The seal 202 is a circular sealing structure, and a sealing cone surface 206 is provided at the central sealing port of the seal 202.

[0023] The guide member 203 includes a connecting part 2031 and a guide part 2032. The connecting part 2031 has a circular structure and the guide part 2032 has a conical structure. The tip of the conical part 2031 is fixedly connected to the connecting part 2031.

[0024] The guide cone 205 and the sealing cone 206 have different tapers.

[0025] The mating end of the connector 104 is provided with a sealing arc surface 1041 and a guide arc surface 1042. The sealing arc surface 1041 is located at the end of the lower air passage 105, and the guide arc surface 1042 is located at the lower edge of the sealing arc surface 1041. The curvature of the sealing arc surface 1041 and the guide arc surface 1042 matches the sealing cone surface 206 and the guide cone surface 205, respectively.

[0026] The elastic element 102 is a spring.

[0027] The two ends of the elastic element 102 are connected to the fixed seat 101 and the connecting rod connecting seat 106 respectively. The connecting rod connecting seat 106 is a ring structure nested on the outer wall of the connecting rod 103.

[0028] The working principle of this utility model is as follows: Figure 1-3 As shown, the male connector 1, through the elastic element 102, allows the connector head 104 to swing left and right, achieving free deflection of the connector head 104. When the connector head 104 enters the guide cone surface 205 of the female connector 2, the guide arc surface 1042 of the connector head 104 contacts the guide cone surface 205, and the guide cone surface 205 guides the connector head 104 to slide until the sealing arc surface 1041 of the connector head 104 and the sealing cone surface 206 are tightly fitted to achieve a seal, ensuring no air leakage between the male connector 1 and the female connector 2. Gas can flow within the upper air passage 204 and the lower air passage 105, completing the gas delivery function. The above process is the automatic alignment process of this solution.

[0029] Furthermore, the elastic element 102 not only provides the connector 104 with free deflection, but also provides stress. By continuously shortening the distance between the fixed seat 101 and the connector 104, the elastic element 102 is compressed. After compression, the elastic element 102 can continuously provide support for the connector 104, ensuring a tight connection between the connector 104 and the sealing cone surface 206.

[0030] Furthermore, the mating end of the connector 104 is provided with a sealing arc surface 1041 and a guide arc surface 1042. The sealing arc surface 1041 serves a sealing function, while the guide arc surface 1042 serves a guiding function. After prolonged operation, the wear area of ​​the connector 104 is mainly the guide arc surface 1042, while the wear of the sealing arc surface 1041 is less, ensuring the longevity of the seal.

[0031] Furthermore, by using different tapers to distinguish the guide cone surface 205 and the sealing cone surface 206, the guiding and sealing functions of different parts of the connector 104 can be achieved.

[0032] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
