Technical field

The present invention relates to an aerosol intermittent spray device that automatically injects a liquid content of an aerosol product at regular intervals. * Only the gas phase of an aerosol container is supplied to a pressurized chamber via a gas phase flow suppressor. When the pressurized chamber is introduced above the set pressure, the liquid phase in the aerosol container can be injected from the nozzle without passing through the suppressor at all. injection interval to be as the sharpened when requested the working accuracy is also the related unintentionally altered]? small aerosol intermittent injection apparatus possibility of _β

Background technology

Conventionally, this type of injection device opens and closes the valve by sensing the temperature change due to the latent heat of vaporization at the time of injection of the aerosol content liquid with a thermosensitive element. * ^ Passes the aerosol content liquid by a certain limited amount Various devices have been proposed, such as one that reserves in a certain space through a suppressive substance to be caused and performs injection when the pressure in the reserved space exceeds a certain pressure. * However, these devices have been proposed. Both methods were extremely difficult to implement and could be put to practical use. That is, the former heat sensitive material is used.

0: 'FI τ,, ΊΡΟ The equipment has the drawback that the operating sensitivity of the sensible element is large, the injection interval and the injection amount are largely changed due to the difference in the ambient temperature due to the new use site and the use period. * In the latter device, which suppresses the appropriate amount of aerosol content liquid with a suppressing substance. * In addition, since the generation rate is constant, the injection interval and injection amount are changed.In addition, this suppressive substance causes a filter effect and changes the content of the content and clogs the suppressive substance. ] 7 * It had drawbacks such as extremely difficult to adjust the jet flow rate, which caused difficult injection of high viscosity materials. In addition, all of the various intermittent injection devices proposed so far require extremely high machining precision, and cannot be put to practical use if production errors are taken into account. .

Further, there has been no device which can easily change the injection amount in one injection by control from the outside of the device. Further, the conventional intermittent injection device such as a Japanese patent There is also a device that controls the opening and closing of a valve using a gas phase, such as the intermittent injection device disclosed in the official gazette ^ 89 16 196 8 and USP K 3 360 165. The toe is the lower edge of the pressing body pressed into the gas phase as the pressure means before opening the valve.

Furthermore, the present invention has a configuration in which, for this purpose, only the gaseous phase passes through the suppressor and is introduced into the chamber, and the content liquid is ejected through the suppressor by a nozzle. It does not provide an intermittent injection device.

Further, the invention is to provide an intermittent injection device having a configuration capable of arbitrarily changing the injection amount of the aerosol content liquid three times by adjusting the duration of one injection to an arbitrary value. .

Disclosure of the invention

A chamber that communicates with the gas phase of the aerosol container is provided via a suppressor that can suppress the flow of the gas phase of the aerosol product *. After a certain period of time, when the pressure chamber becomes more than the set value, the pusher BE receives this pressure and moves so that it moves at least one position. Then, the above-mentioned pressurized chamber communicates with the outside air, and the gas phase in the pressurized chamber is discharged to the outside, and at the same time, the liquid phase of the aerosol container and the nozzle communicate with each other to form a liquid phase. * A valve mechanism that closes the valve when the pressure in the pressurized chamber is lower than the set pressure is provided. This means that the liquid in the aerosol container can be sprayed at regular intervals. * If the liquid is a fragrance * If it is a deodorant, etc. also of the door also liquid content Ru can and child that makes lasting insecticidal effect of awe time in the warehouse or the like of it if * unmanned an insecticide _β also the above-described configuration Ru is possible to get a deodorant or anti-odor effect Between liquid ejection-'' ^{I? 0} Unintentional change in distance * It is something that can cause inapplicability, etc.

Inhibition rest capable of suppressing the flow of the gas phase of the aerosol products of the appropriately even Ru can distribute vapor stretchability with elastic material quality also formed of柙圧means and鉬合Seko Ru operable from _¾ outside because of By controlling the pressure means, the degree of gaseous phase flow is arbitrarily changed to suppress gaseous phase flow. By simply changing it and adjusting the rise time to the set force in the pressurized chamber, 1? The jetting interval of the aerosol content liquid can be set to the descendants.

In addition, a valve body that can control the flow rate of the gas phase is formed in the passage that connects the pressurizing chamber and the outside air. Arbitrary adjustment of the restoration time to the position * The opening duration of the valve mechanism is arbitrarily changed.)) Duration of ejection of the content liquid * That is, the content liquid in one ejection It is said that the amount of eruption can be severe.

In addition, the ff body provided in the chamber is formed so that at least a part of its position changes by a fixed distance instantly when the force in the chamber exceeds the set value. j? CA BF When the pressure inside the room is lower than the set pressure, the pressing body changes its position and opens the valve mechanism, and at the same time, changes a certain distance instantaneously, resulting in insufficient position change of the pressure body. As a result, the valve mechanism cannot be opened. * The EE room ff force cannot be increased.

In addition, the intermittent injection mechanism is formed so that it can be attached to and removed from the aerosol container with the valve mechanism. * This allows it to be detached from the aerosol container and reduced in size. In addition to enabling easy handling in such cases as above, it also prevents the occurrence of jetting accidents when not in use. <もの If it conforms to the standard, install it in a conventionally known aerosol container to perform intermittent injection. The valve mechanism of the aerosol container is formed so that the gas phase and the liquid phase can be separated and distributed. It is possible to install a gas-liquid separation mechanism in the valve mechanism so that only the gas phase flows into the pressurizing chamber and the content liquid flows into the * valve mechanism.

In addition, the pressing body is formed by a diaphragm, which makes it possible to instantaneously invert when the pressure in the pressurized chamber exceeds a set pressure, and to open the valve mechanism reliably. It is simple and easy to maintain airtightness in the pressurized chamber.
