[0015] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail below by combining with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.
[0016] In order to explain the technical scheme of the utility model, the following specific embodiments are used to explain.
[0017] As Figures 1-4 shown, the installation-free negative pressure sputum suction device provided by the embodiment includes a host computer 1 and a collection bottle 2, the collection bottle 2 includes a bottle body 3 and a bottle cap 4, the bottle cap 4 is provided with a suction inlet 41, the side wall of the bottle body 3 is formed with a positioning notch 31 from the bottom upwards, the top of the positioning notch 31 is formed with a guide hole 32 upwards, the bottle body 3 is provided with a gas outlet 33 communicating with the guide hole 32, the bottom of the front side of the host computer 1 is provided with a mounting position 5, the rear side of the mounting position 5 is provided with a vertical pipe 6 matching the shape of the positioning notch 31 upwards, the top of the vertical pipe 6 is provided with a plug 61 matching the guide hole 32, and the vertical pipe 6 communicates with the negative pressure pump inside the host computer 1.
[0018] In the structure, the collecting bottle is directly inserted into the installation position of the main machine during use. The installation position is circular and in close contact with the bottom of the bottle body, and a certain friction force exists between the two, so the collecting bottle will not shake at will. At the same time, the shape of the vertical pipe on the main machine also matches the shape of the positioning gap of the collecting bottle. The lower part of the positioning gap is inserted into the vertical pipe, and then the collecting bottle is directly pressed downward, so that the collecting bottle moves downward along the vertical pipe until the plug at the top of the vertical pipe is inserted into the guide port. The guide port is circular, the top of the plug 61 has a small hole 62, and the outer periphery of the plug 62 has two sealing rings 63, so that the sealing property of the two is guaranteed after insertion. Therefore, through the structure of the embodiment, the collecting bottle is directly inserted into the installation position, so that the automatic connection of the main machine and the collecting bottle is realized, and the operation complexity is reduced, and the soft tube between the main machine and the collecting bottle does not need to be repeatedly disassembled and connected.
[0019] During work, the negative pressure pump of the main machine works, and through the vertical pipe, the plug, the guide port and the air outlet, negative pressure is generated in the collecting bottle, and then the sputum suction operation is realized. Since the position of the air outlet 33 is relatively high, and a certain distance exists between the air outlet 33 and the suction inlet 41, it can be guaranteed that sputum will not be sucked into the air outlet. Further, the top of the bottle cap 4 is formed with a circumferential avoiding ring 42, the top of the air outlet 33 is located in the avoiding ring 42, and the suction inlet 41 is located at the center position of the bottle cap 4. In this way, the top of the air outlet 33 is located in the avoiding ring, which further improves the height of the air outlet, and the avoiding ring is a ring-shaped space, which does not affect the negative pressure air extraction. Moreover, when the bottle cap is rotated, the bottle cap will not interfere with the air outlet, which is convenient for operation.
[0020] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
