【考案の詳細な説明】 本案は、エアポンプ付き小型手動噴霧器に係
る。[Detailed description of the invention] The present invention relates to a small manual sprayer with an air pump.

一般によく知られている噴霧器に、液体を収容

噴出させることにより、噴霧を得るものがあり、
園芸用等に広く用いられている。 In a commonly known atomizer, compressed air is supplied by an air pump into a container containing a liquid to pressurize the liquid, and the pressurized liquid is sent through a valve to an atomizing head where it is spun. There are some that obtain spray by passing through a groove and ejecting it from a nozzle while applying high-speed rotation.
Widely used for horticulture, etc.

この種の噴霧器は、通常、液体がリツトル単位
で収容できる大型のものであり、エアポンプが強
力で、手動であつても液体へかなりの圧力を与え

の回転と噴出とを強大にでき、噴霧粒子を微細な
ものにできる。 This type of atomizer is usually large, with a capacity of liters of liquid, and the air pump is powerful and can exert considerable pressure on the liquid, even manually, thus reducing the amount of liquid in the atomizing head. The rotation and jetting can be made stronger, and the spray particles can be made finer.

噴霧を得ることは到底できない。 However, if a small manual sprayer with an air pump for perfumes, etc., which is carried in a handbag or the like is constructed based on the same principle, it will be subject to significant restrictions on the air pump and other components, and it will be difficult to use hydraulic pressure. It is impossible to obtain a good spray with fine particles.

そこで、本案は、液圧が低くとも良好な噴霧が
得られるようにし、小型化を可能にし、また、小

とになる。 With the above configuration, when a liquid is stored in the liquid container 1 and the rotary cylinder 3a of the air pump 3 is rotated to the right or left, the rotary cylinder 3a rotates due to the engagement between the balls 3c... and the endless guide groove 3b. The air pump 3 moves up and down, and the air suction valve C and air discharge valve D move alternately to operate the air pump 3, and compressed air is supplied to the air chamber E. When the rotary cylinder 3a is kept in the raised state, the pressure inside the rotary cylinder becomes high, which causes the plate-shaped piston 1f of the liquid container 1 to be pushed up against the compression spring 1h, and the liquid is equally increased. You will be under pressure.

る。 In this state, the spray head 2 of the spray device 2
When u is pushed down, the stem 2m descends against the compression spring 2t, and the flanged valve body 2l deforms.
The discharge valves A and B are opened, and the pressurized liquid in the liquid container 1 flows into the spray head 2u through the pipe 2p, the small cylinder 2o, and the liquid passage 2r of the stem 2m due to the internal pressure, and the air The compressed air in the chamber E also flows into an air groove 2x and an air passage 2s with a stem 2m depending on the internal pressure.
The two components flow through the spray head 2u, where they are mixed together, and are ejected from the nozzle 2w while being rotated at high speed in the spin groove 2v to be atomized. In this way, when compressed air is mixed with the liquid before it reaches the spin grooves 2v, the spray particles can be made finer.

Since the spray is ejected, the spray particles can be made fine even if the pressure of the pressurized liquid is relatively low, and a good spray can be obtained even if the spray is small. Moreover, since the liquid and the compressed air are stored separately, the stored liquid is less likely to be altered by outside air, and the liquid does not bubble or produce bubbling noise during air supply.
