Abstract

PURPOSE:To control the emitting quantity of mist by regulating the quantity of mist itself atomized, by displacing the baffle provided in the vicinity of a nozzle orifice injecting compressed air up and down by a baffle position control means. CONSTITUTION:When compressed air is sent into a compressed air pipe 9 from a main body apparatus through a hose 14, negative pressure is generated between a nozzle 10 and an air sending opening part by the jet air stream injected from the nozzle 10 and the liquid level in a liquid suction pipe 11 rises by ejecting action to upwardly inject a chemical liquid along with the jet air stream. The air stream having the chemical liquid mixed therewith impinges against the baffle 6b at the leading end of the rod body 6 above the nozzle 10 and the chemical liquid is atomized by this impingement to be scattered in all directions. The mist atomized is discharged to the outside from a mist stream discharge part 4 by the external air pressure from an air introducing pipe 5. Herein, when the rod body 6 is revolved by operating the knob 6a thereof, the baffle 6 moves up and down and the distance thereof from the nozzle 10 changes to regulate atomizing quantity.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an atomizer that is used, for example, to inhale a medicinal solution into the throat, and in particular, the amount of atomization can be adjusted.

(b) Prior Art In general, atomizers are known that apply Bernoulli's principle or Babington's principle to suck up liquid to be atomized with compressed air and atomize it. The structure of a conventional atomizer of this type is shown in FIG.

This atomizer includes a case body 53 having a liquid reservoir 51 at the bottom, an atomized liquid discharge part 52 and an external air introduction pipe 60 at the top, and penetrating through the liquid reservoir 51 of the case body 53. A compressed air pipe 55 is provided with a nozzle 54 on the upper part, and the liquid reservoir part 51 is fitted onto the upper part of the compressed air pipe 55, and the gap between the fittings and the compressed air pipe 55 is used as a passageway 56a, and the liquid reservoir part 51 is provided at the lower part of the compressed air pipe 55. It consists of a water suction pipe 56 provided with a water inlet portion 56b that communicates with the water intake pipe 56. The lower end of the compressed air pipe 55 is connected to a drive device such as a pump via an air supply hose 57. Furthermore, an air supply opening 58 and a baffle ball 59 are provided in the upper part of the water suction pipe 56 in correspondence with the nozzle 54, so that the jet air stream (liquid mixed gas) injected from the nozzle 54 is radially distributed. It is set to disperse.

When using this atomizer, when compressed air is sent to the compressed air pipe 55 through the hose 57, a jet stream is ejected from the nozzle 54. At this time, negative pressure is generated in the fitting gap between the compressed air pipe 55 and the water suction pipe 56, that is, in the upper part of the water passage 56a (near the nozzle), and the liquid stored in the water passage 56a (the liquid level in the liquid reservoir 51) is generated. The water level (dynamic water level) rises due to the ejecting action and mixes with the jet stream. In this state, the liquid mixture gas collides with the baffle pole 59 from the air supply opening 58, is atomized, is radially dispersed, and is sent outward from the atomized liquid discharge section 52 of the case body 53 to form stones.

(c) Problems to be Solved by the Invention In the above-mentioned conventional atomizer, in order to adjust the amount of atomization, the external air intake port of the air introduction tube can be opened and closed, and the amount of air introduced into the interior can be adjusted. By adjusting and changing the force of the mist released to the outside, the amount of mist coming out from the outlet is substantially changed. Therefore, ■Changes in the amount of atomization depend on changes in the amount of air introduced.The amount of air introduced depends not on the area of the intake port but on the pressure difference inside and outside the atomizer, so opening and closing the intake port Even if there is a noticeable change in the amount of atomization, it is difficult to see the change in area when the door is half open or closed.

■The amount of mist created in the atomization chamber does not change, only the amount that exits outside changes, so more mist accumulates inside and the efficiency of liquid recovery is poor.

■The amount of mist emitted when the intake port is closed is drastically reduced.

There were other problems.

In view of the above, an object of the present invention is to provide an atomizer that can adjust the amount of mist itself to be atomized and the amount of clouds emitted.

(d) Means and operation for solving the problem The present invention provides that the amount of mist to be atomized corresponds sensitively to the distance between the nozzle hole from which compressed air is ejected and the baffle placed opposite the nozzle hole. The atomizer of the present invention includes a case body equipped with a liquid reservoir in the lower part, an air introduction pipe and a mist discharge part in the upper part, and the liquid reservoir of this case body. a compressed air tube passing through the section and having a nozzle at the top end;
A liquid suction pipe that communicates with the nozzle of the compressed air pipe and a liquid reservoir, and a baffle provided near the nozzle, wherein the baffle is formed at the tip and the other end is held in the case body, and characteristically includes a baffle position adjusting means that can change the distance between the baffle and the nozzle.

In this atomizer, by displacing the baffle up and down with the baffle position adjustment means, the distance between the nozzle and the puffful changes, the amount of mist to be atomized changes, and the amount of mist released accordingly changes. Change.

(E) Examples The present invention will be explained in more detail with reference to Examples below.

<Embodiment 1> FIG. 1 is a sectional view of an atomizer showing an embodiment of the present invention.

In this embodiment of the atomizer, a case body 1 is composed of an upper case 2 and a lower case 3, each having a substantially cylindrical shape.

A phase flow discharge path 4 for discharging a mist flow is provided on the upper side of the upper case 2, and a cylindrical air introduction pipe 5 vertically installed inward is provided on the ceiling surface of the upper case 2. It is provided. A rod body 6 is fitted into the air introduction pipe 5, and the upper part of the rod body 6 is threaded, and the rod body 6 is screwed into a screw hole 7a provided in a support body 7 protruding from the upper surface of the upper case 2. Together (threaded part work 5), they are held on a support body 7. Also,
A knob 6a is provided at the upper end of the rod 6, and by operating the knob 6a and rotating the rod 6, a baffle 6b at the tip can be moved up and down. The baffle 6b also serves as an air flow path regulator.

The support body 7 is cylindrical, but has an open lower part b on the side,
It also communicates with the air introduction pipe 5, with the lower b forming an external air inlet of the air introduction pipe 5.

A liquid reservoir 8 is provided at the bottom of the lower case 3, and a nozzle 10 is inserted through the liquid reservoir 8 and at the tip of the upper part.
A compressed air pipe 9 is provided upright.

A liquid suction pipe 11 is fitted into the compressed air pipe 9 and has a water guide pipe I2 at its lower end communicating with the liquid reservoir 8.

On the inner wall surface of this liquid suction tube 11 and the outer peripheral surface of the compressed air tube 9,
A suction channel 13 is formed.

The nozzle 10 and the upper end of the suction channel 13 are in the same horizontal plane, and this plane and the baffle 6b at the tip of the rod 6 are opposed to each other. This buff fluro b is formed into a hemispherical shape. The lower end of the compressed air pipe 9 is connected to a main unit (not shown) via a hose 14, and receives compressed air from the main unit.

In this embodiment of the atomizer, when compressed air is sent from the main unit to the compressed air pipe 9 through the hose 14, the compressed air is ejected from the nozzle 10 as a jet stream. This jet airflow forms a negative pressure between the nozzle 10 and the air supply opening, and the liquid level in the liquid suction tube ll, which was at the same level as the liquid level in the liquid reservoir 8, rises due to the ejecting action.
It is ejected upward along with the jet stream. Then, the airflow mixed with the chemical liquid collides with the baffle rod b at the tip of the rod 6 above the nozzle 10. This collision atomizes the chemical solution,
Scattered in all directions. On the other hand, since external air is introduced through the air introduction pipe 5, the external air pressure pushes the mist upward in the atomization chamber around the air introduction pipe 5, and the mist is released from the mist discharge part 4 to the outside. .

When the rod 6 is rotated by operating the knob 6a of the rod 6,
The baffle 6b at the tip moves upward or downward,
The baffle 6b at the tip and the gear knob of the nozzle 10 change, and the amount of atomization changes accordingly.

<Embodiment 2> FIG. 2 is a sectional view of an atomizer showing another embodiment of the present invention. The basic configuration is the same as that of the atomizer shown in FIG.

The feature of this embodiment atomizer is that a cylindrical body 16 is installed below the ceiling surface of the upper case 2, and the air introduction pipe 5 is screwed into this cylindrical body 16. A puffful 18 is integrally provided at the lower end of the man tube 5, and by adjusting the air introduction tube 5 up and down, the baffle 18 can be moved up and down, and the distance between the nozzle 10 and the baffle 18 can be changed and adjusted. It is. An operating knob 5a is formed at the upper end of the air introduction pipe 5 to facilitate rotation.
In addition, the lower end of the air introduction pipe 5 is provided with a baffle 1 made of, for example, a cross.
8 is fixed, and therefore an air hole 19 is formed in the cavity of the cross member.

The general operation of atomization is similar to the first embodiment.

<Embodiment 3> FIG. 3 is a diagram showing the main parts of a further embodiment of the atomizer of the present invention.

In this embodiment atomizer, the one in embodiment 2 is different from the air introduction pipe 5.
Although one baffle 18 is integrally formed coaxially at the tip of the compressed air pipe 9 and the four air pipes 5 are arranged coaxially, and the nozzle IO and the baffle 18 are opposed to each other. On the other hand, the air introduction pipe 5 is placed at the tip of the air introduction pipe 5 with its axis shifted.
A plurality of baffles f8a, 1 in a concentric circle larger than the diameter of
8b, 18c, and 18d, and the compressed air pipe 9 is arranged so that the nozzle 0 is located one point below the concentric circles. Each baffle has a different shape,
The baffle 18a has an inverted conical shape, the buckle 18b has a cylindrical shape, the baffle 18c has a hemispherical shape, and the baffle 18d has an inverted roof shape.

In this atomizer, when the air introduction pipe 5 is rotated, the tip of the air introduction pipe 5, and thus each baffle 18a, 18b,
As the distance between 18c, 18d and the nozzle 10 changes, the baffle facing the nozzle 10 changes. As mentioned above, when the distance between the baffle and the nozzle 10 changes, the amount of atomization changes, but in this example,
The baffle facing the nozzle 10 changes, that is, the shape of the baffle facing the nozzle 10 changes. This results in
The particle size of the atomizer changes. Therefore, in this embodiment, both the amount of atomization and the particle size can be adjusted.

In each of the above embodiments, the nozzle 10 of the compressed air pipe 9 and the upper end of the liquid suction pipe 11 are located horizontally, but instead of this, the jet stream ejection part is as shown in FIG. May be used. The jet air flow ejection part shown in FIG.
The upper end of the nozzle 10 is extended upwardly than the nozzle 10.
An air supply opening 19 is provided between the baffle 18 and the baffle 18 .

In addition, in Embodiment 3, it is assumed that the four air tubes 5 are moved up and down to raise and lower the baffle, but the mechanism as in Embodiment 1 is adopted, and the air introduction tube is fixed. Alternatively, a plurality of baffles may be provided at the tip of the rod to move the rod up and down.

(f) Effects of the Invention According to the present invention, a baffle is formed at the tip, the other end is held in the case body, and a baffle position adjustment means is provided that can change the distance between the baffle and the nozzle. By freely adjusting the distance between the baffle and the nozzle through operation, the amount of mist atomized can be freely adjusted both analogously and digitally. In addition, the air introduction pipe is always open, and as long as the pressure of the compressed air ejected from the nozzle does not change, a constant amount of outside air is always introduced. Therefore, the force of the mist released changes depending on the amount of atomization. Never. Adjusting the amount of atomized mist released does not directly control the amount of mist that is released from the atomization unit to the outside, but rather directly controls the amount of mist that is generated.
The amount of mist that accumulates inside is small, allowing for efficient atomization.
