Description

Atomizer {a spray without check ball}

The present invention relates to a fine atomizer, and more specifically, to the upper part of the lower end of the support housing to form a sealed tube upwards and to form a distribution hole in the piston and install a check valve which is driven up and down in the distribution hole of the piston Since the generation of residual pressure in the fine atomizer is prevented and a check ball is not used, the structure is simplified, and thus the manufacturing is easy, and there is no contamination of the contents, and it is related to the fine atomizer which ensures smooth operation.

As shown in FIG. 3, a micro spraying machine generally used, a metal check ball 2 is disposed on the inlet hole 1a below the support housing 1 of the micro spraying machine, and the piston 3 is connected to the valve barrel. (4) The valve hole 4a formed on the valve barrel 4 is opened and closed while the upper and lower operations thereof, and the contents are introduced or blocked in accordance with the vertical movement of the check ball 2 in the support housing 1. However, such a conventional atomizer (A) using a metal check ball (2) is dissolved or corroded into the contents while the check ball (2) is in contact with the contents of the chemical contaminates the skin or hair of the user using the contents Such malfunction may occur due to dissolution or corrosion, which is inconvenient to use. Especially when spraying viscous contents, there is a viscosity between the check ball 2 and the inlet hole 1a. (2) up and down operation is not smooth Residual pressure is generated and a malfunction occurs that is not driven up and down, and the check ball 2 becomes impossible to completely close the inlet hole 1a, and malfunctions, and the check ball 2 and the inlet hole 1a ) Is not easy to manufacture because of the point contact, and the conventional fine atomizer using the check ball as described above, because a large number of parts such as the check ball (2), ball cover (5) is used There was an expensive problem.

An object of the present invention is to solve this problem, the metal check ball is not installed, the structure is simple, easy to manufacture, there is no fear of malfunction, and the check valve is driven up and down to open the outflow hole of the piston By opening and closing, it is possible to prevent the occurrence of residual pressure to ensure reliable operation and to provide a fine atomizer capable of preventing contamination due to dissolution and corrosion of the metal checkball.

This object of the present invention is a support housing in which an upper end is opened so that a piston is received and an outlet hole is formed at a lower end thereof, and a closed tube extending in a predetermined length to an upper portion of the outlet hole into which the lower end of the piston is inserted is formed therein, and the support housing. The piston is formed in the lower end and the first end and the second through-hole formed in the longitudinal direction in the center and the first end of the piston and the first end of the piston can be moved up and down in close contact with the inner wall of the The check valve for opening and closing the second distribution hole is achieved by the fine atomizer according to the present invention including a valve body formed at the bottom.

With reference to the accompanying drawings, the fine atomizer according to the present invention will be clearly understood its features and advantages by the embodiments described in detail below.

In the fine atomizer (A) according to an embodiment of the present invention, as shown in Figures 1 and 2a, b, the upper part is open and the outlet hole 11 is formed in the lower portion and the upper part of the outlet hole 11 An end portion of the support tube 10 extending in a predetermined length is formed in the support housing 10 and the inner wall 10a of the support housing 10, and is driven up and down and inserted into and inserted into the sealed tube 12. 21 is formed at the lower end and the piston 20 having the first and second flow holes 22 and 23 formed in two stages in the longitudinal direction at the center thereof, and in the first flow hole 22 of the piston 20. The valve 30 is formed at the lower end of the check valve 31 is inserted into the liftable to open and close the second flow hole (23).

The upper end of the support housing 10 is covered with a closed cap (13).

A piston body 20a having an outer wall in which a lower portion thereof is in close contact with the inner wall 10a of the support housing 10 is formed on the outer side of the upper end of the piston 20, and extends downwardly from the piston body to the first distribution hole ( 22 and a through hole 24 communicating with the first extension end 25 formed on the lower side, and extending downward from the first extension end 25, the second distribution hole 23 is formed and the closed tube. An insertion end 21 inserted into and out of 12 is formed. The piston 20 is elastically supported upward by a spring 40 interposed between the piston 20 and the bottom of the support housing 10.

The valve body 30 which is driven up and down in the first distribution hole 22 of the piston 20 and opens and closes the second distribution hole 23 has a support jaw 32 protruding in the middle and the support jaw is formed. Spring 41 is interposed between the piston and the piston is elastically supported upward. A through hole 33 is formed above the check valve 31 at the lower end of the valve body 30. Since the spring 41 has a smaller elastic force than other springs 40 disposed below, the spring 41 is first stretched. A flow path 34 extending in the longitudinal direction is formed in the valve body 30. It is.

When the fine atomizer (A) according to an embodiment of the present invention having such a structure presses the sprayer for spraying the contents, the valve body 30 is lowered while pressing the spring 41 and the valve body 30 The bottom check valve 31 closes the second flow hole 23 and at the same time, the through hole 24 formed in the lower end of the first extension end 25 and the through hole 33 formed adjacent to the check valve 31; While arranged in a communication position (shown in FIG. 2A), the contents filled in the lower portion of the support housing 10 are discharged to the outside along the flow path 34 of the valve body 30 to start spraying and at the same time the piston 20 Insertion end 21 of the () to close the closed tube 12 of the support housing 10. In such a state to overcome the repulsive force of the spring 40 and when the valve body 30 is further lowered downward piston 20 ) Is lowered so that the contents filled between the outer wall of the support housing 10 and the sealed tube 12 passes through the through hole 33 of the valve body 30. The valve body 30 is upwardly lifted upward by the restoring force of the springs 40 and 41 in such a state as shown in FIG. 2B. Since the space in the support housing is expanded in a closed state, the pressure is lowered, so that the contents of the lower portion are introduced back into the support housing 10 through the outflow hole 11 of the support housing 10.

As described above, the fine atomizer according to the present invention can install a closed tube under the support housing and insert an insertion end inserted into the sealed tube on the piston, thereby eliminating the use of a conventional ball and ball cover. Simplifies operation, ensures smooth operation, prevents contamination of the contents by metal balls, and installs a distribution hole in the piston and a check valve in the distribution hole to prevent the occurrence of residual pressure remaining in the sprayer. There is an excellent effect that can ensure a smooth operation.
