sprayer

Abstract

The nebulizer of the present invention may include: a main body, which is formed with a suction port at the rear of the air supply module assembly part, and is formed with a neck in a form whose internal cross-sectional area becomes smaller as it goes forward in the front part of the air supply module assembly part; The liquid barrel, which is assembled in the liquid medicine barrel assembly part of the main body, has a liquid medicine barrel cover and a liquid medicine discharge port. The liquid medicine barrel cover is equipped with a check valve for flowing with external air at the liquid medicine injection port. The liquid medicine injection port is opened and closed, and the liquid medicine discharge port is formed at the lower part; the air supply module is installed in the air supply module assembly part of the main body, so that the external air is sucked into the main body and spit out to the outside through the neck; the transfer pump, It is connected to the liquid medicine discharge port of the liquid medicine barrel through a connecting pipe; the spray nozzle assembly is connected to the transfer pump through a connecting pipe; and the fixed cover is separated and combined with the end of the neck of the main body, and is open at the front and rear. of tubular.

Description

technical field [0001] The present invention relates to a nebulizer, and more specifically, to a nebulizer capable of adjusting the spraying and spraying distance of a liquid medicine, and which facilitates assembly of internal components of the nebulizer. Background technique [0002] Sprayers that apply pressure to a liquid to spray a larger area are variously classified according to the operation method, application, size, etc. That is, depending on the application and spray object such as household use, agricultural use, and industrial use, the size, shape, spray area, etc. of the particles sprayed in mist or granular form need to be varied, and thus various forms of sprayers are required. [0003] On the other hand, in the case of sprayers used for epidemic prevention or sterilization, spraying the chemical liquid evenly over a wider area is beneficial in terms of epidemic prevention effects, so sprayers with spray particle sizes within tens to hundreds of μm are prefer...

Problems solved by technology

[0008] In the case of the above-mentioned conventional liquid medicine spraying device, part of the pressure generated behind the nozzle due to the driving of the fan is transmitted to the liquid medicine tank, and the medicine inside the liquid medicine tank is depleted by the high-pressure air thus transmitted to the liquid medicine tank. The liquid is pumped and sprayed through the liquid nozzle. For this series of processes, it is not only necessary to arrange multiple pipes inside the main body, but also to equip the middle section of the liquid discharge pipe with another device for regulating the liquid. device, so there is a problem that the structure of the liquid medicine spray device is complicated
