As used in the description of the embodiments of the present utility model and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0029] See Figures 1-4 , an air nozzle connection device is proposed in the embodiments of the present utility model. The air nozzle connection device has the technical effect of being convenient for installation and disassembly. The air nozzle connection device includes an air nozzle joint 10, a first housing 20, a fan 30, a second housing 40, and a first sealing ring 50. The specific structure is introduced as follows:

[0030] The air nozzle joint 10 includes a connecting pipe 11, and the outer side of the connecting pipe 11 is a smooth surface without threads. It can be understood that the air nozzle joint 10 can have various styles to adapt to different inflatable objects, but the connecting pipe 11 of each air nozzle joint 10 is the same.

[0031] The first housing 20 is provided with a first air outlet passage 21. The fan 30 is arranged in the second housing 40, the second housing 40 is arranged in the first housing 20, and the second housing 40 is provided with a second air outlet passage 41 communicating with the air outlet of the fan 30. An installation space is provided in the first housing 20 so that the second housing 40 can be installed in the first housing 20. At the same time, the second housing 40 also has an installation space so that the fan 30 can be installed in the second housing 40. The fan 30 can specifically be a low-pressure fan 30, and the fan 30 has an air inlet and an air outlet. The first air outlet passage 21 is arranged on the first housing 20, and the second air passage is arranged on the second housing 40 and communicates with the air outlet of the fan 30.

[0032] The first sealing ring 50 is clamped between the first air outlet passage 21 and the second air outlet passage 41. The internal spaces of the first air outlet passage 21 and the second air outlet passage 41 communicate to jointly form an air outlet channel 80. The axes of the first air outlet passage 21 and the second air outlet passage 41 can be collinear and have the same inner diameter. The first sealing ring 50 plays a sealing role to avoid air leakage.

[0033] In the present utility model, a part of the first sealing ring 50 protrudes into the air outlet channel 80; the connecting pipe 11 of the nozzle connector 10 is inserted into the air outlet channel 80 and presses the part of the first sealing ring 50 that protrudes into the air outlet channel 80. It can be understood that the length of the nozzle connector 10 is greater than the length of the first air outlet passage 21, so that the nozzle connector 10 can press the part of the first sealing ring 50 that protrudes into the air outlet channel 80 after being inserted into the air outlet channel 80. The first sealing ring 50 has elasticity. When the nozzle connector 10 presses the first sealing ring 50, on the one hand, sealing is achieved, and on the other hand, the nozzle connector 10 is fixed by the frictional force between the nozzle connector 10 and the first sealing ring 50. Thus, the nozzle connector 10 only needs to be directly inserted into the air outlet channel 80 to achieve both sealing and fixing at the same time, and it can be directly pulled out during disassembly. The installation and disassembly are both very convenient and fast, improving the user experience.

[0034] Further, the material of the nozzle connector 10 is PC (polycarbonate), and the material of the first sealing ring 50 is TPU (thermoplastic polyurethane elastomer). The hardness of the first sealing ring 50 can be 65-75 degrees.

[0037] Further, a first groove 211 is provided on the end face of the first air outlet passage 21, and the first side wall 51 of the first sealing ring 50 is embedded in the first groove 211. Thereby, the first sealing ring 50 can be fitted and fixed on the end face of the first air outlet passage 21, facilitating the installation and positioning of the first sealing ring 50.

[0038] Further, the nozzle connection device further includes a second sealing ring 60. The first housing 20 is provided with a first air inlet passage 22, and the second housing 40 is provided with a second air inlet passage 42 communicating with the air inlet of the fan 30.

[0039] Specifically, the first air inlet passage 22 is provided on the first housing 20, and the second air inlet passage 42 is provided on the second housing 40. The second air inlet passage 42 communicates with the air inlet of the blower 30. The second sealing ring 60 is clamped between the first air inlet passage 22 and the second air inlet passage 42 to play a sealing role. The internal spaces of the first air inlet passage 22 and the second air inlet passage 42 are communicated to form an air inlet passage 90. The air outside the first housing 20 enters the air inlet of the blower 30 through the air inlet passage 90. The axes of the first air inlet passage 22 and the second air inlet passage 42 are collinear and have the same inner diameter.

[0040] Further, the second sealing ring 60 includes a second side wall 61 and a second clamping wall 62 protruding from the inner side of the second side wall 61. The width of the first side wall 51 is greater than the width of the first clamping wall 52.

[0041] The second clamping wall 62 is clamped between the first air outlet passage 21 and the second air outlet passage 41. Specifically, the end faces of the first air inlet passage 22 and the second air inlet passage 42 press against the first clamping wall 52.

[0042] Further, a second groove 221 is provided on the end face of the first air inlet passage 22, and the second side wall 61 of the second sealing ring 60 is embedded in the second groove 221. Thus, the second sealing ring 60 can be fitted and fixed to the end face of the first air inlet passage 22, facilitating the installation and positioning of the second sealing ring 60.

[0043] Further, the first housing 20 includes a first main housing 23 and a first cover 24. The first main housing 23 is provided with a first inner cavity 25 for accommodating the second housing 40, and the first cover 24 is detachably covered on the first inner cavity 25 of the first main housing 23.

For example, the second cover 44 can be connected to the second main housing 43 by a buckle or a fastener, which is not specifically limited in the present utility model. Further, the installation method of the third sealing ring 70 is as follows: an accommodation groove for accommodating the third sealing ring 70 is provided on the outer side of the second cover 44. The third sealing ring 70 is arranged in the accommodation groove and partially exposed outside the accommodation groove. When the second cover 44 is covered on the second main housing 43, the second cover 44 and the second main housing 43 jointly press the third sealing ring 70.

[0045] Both the first air outlet passage 21 and the first air inlet passage 22 can be arranged on the first cover 24. Both the second air outlet passage 41 and the second air inlet passage 42 can be arranged on the second main housing 43. When the first cover 24 is covered on the first main housing 23, the first air inlet passage 22 is aligned with the second air inlet passage 42 and presses the first sealing ring 50, and the first air outlet passage 21 is aligned with the second air outlet passage 41 and presses the second sealing ring 60.
