Abstract

The invention relates to a sealing connecting structure used for an atomizer air chamber and an outer barrel body. The sealing connecting structure comprises an outer barrel body, the air chamber anda screwing cover. An installation hole is formed in the outer barrel body, and an outer ring-shaped table extending towards the outer side is arranged at the position of a hole opening of the installation hole. The air chamber penetrates the outer ring-shaped table and the installation hole at the same time, and an inner threaded face is arranged on the inner cover face of the screwing cover. Thesealing connecting structure further comprises a first sealing part and a second sealing part, and an inner ring-shaped table stretching into the outer barrel body is arranged in the screwing cover. The inner threaded face is in threaded connection to the outer ring-shaped table, and a sealing interval space is formed between the inner ring-shaped table and the inner threaded face. The outer ring-shaped table can be inserted in the sealing interval space, the first sealing part is extruded in the outer ring-shaped table and the sealing interval space, and a sealing effect is formed. The secondsealing part is located between the inner ring-shaped table and the outer side wall of the air chamber, and a sealing effect is achieved. By means of the sealing connecting structure, when the screwing cover is slightly loosened, the relatively good sealing performance can be still maintained.

Description

technical field [0001] The invention relates to the technical field of nebulizers, in particular to a sealed connection structure for the air chamber of the nebulizer and the outer barrel body. Background technique [0002] A sprayer is a device that uses air suction to turn potions or other liquids into mist and spray them onto other objects evenly. [0003] The sprayer mainly consists of an outer barrel body and a spray mechanism. The spray mechanism mainly includes a pump and an air chamber. See figure 1 As shown, an installation hole 3 is provided on the outer barrel body 2, and the air chamber 1 is arranged in the installation hole 3. Since the air chamber 1 will reciprocate and twitch up and down during actual use, the air chamber 1 will move the inside of the outer barrel body 2 If the sealing performance between the air chamber 1 and the wall of the installation hole 3 cannot be guaranteed, the liquid medicine is easy to seep out, and once it remains on the user's s...
