DE2732358A1 - Atomiser spray bottle - with venturi and double valve for atomising medium and substance to be atomised - Google Patents

Abstract

An atomiser spray bottle is fitted with a double two-way valve, one side coupled to the atomiser medium (compressed air or CO2) and the other to the substance to be atomised. The two outlets from the valves lead to a venturi section where the two flows are mixed and atomised. Appts. is a replacement for aerosol bottles and removes the fears of ionosphere damage and other environmental drawbacks of aerosols.

Description for carburetor spray can

The carburetor spray can is a consistent further development and Supplement to the classic membrane spray can.

While the membrane spray can developed by me, the spray material, which is filled in a membrane, by means of compressed air in the can (approx. 5.5 At.), Acting on the membrane, drives directly into the spray head and there in one If the atomization and turbulence area is torn into tiny droplets, the new one goes Carburetor spray cans take a major step in nebulization.

In the case of the carburetor spray can, a separately saved Gas (compressed air, carbon dioxide, etc.) completely "gasifies" the spray material and makes it microfine and "dry" blasted.

For this purpose, a two-way double valve "A" is on the spray can with carburetor mixer spray head "A" attached. The fixed part of this facility6 is firmly and tightly connected to the can body "above". These.

Zweiveg double valve has two "5.4" inlets protruding into the inside of the can for the gasification medium "8" and for the spray material. There are each the connection for the pressure vessel of the gasification medium and the membrane of the fuel are provided. The membrane is molded on by the manufacturer of the valve device at the same time as ~. The pressure vessel for the gasification medium should be animal-assisted and by a pressure capsule specialist to be delivered. The capsule can be made of metal or fiber-reinforced plastic. There are also plastics that match the properties of resistant metals.

In the case of carburetor aerosol cans without a membrane, there is a "5" at the inlet Riser tube "11" attached. The two entry channels "5.4" each open into one separate two-way valve area, in which a spring "14" the sealing ring "15" and the movable filler and discharge nozzle is "12". Set the entry channels "5.4" continues in the two nozzles "12".

At this point it must be noted that when filling the spray material the air inside the can is not vented but rather compressed the volume of the spray material including the membrane. This tense air serves as additional Conveying load on the spray material. This regulation does not apply if no membrane is used and the spray is prone to oxidation.

Then the free can interior must be filled with non-oxidizing gas be. This gas is expediently filled before the spray material is filled in, so that the space-consuming spray material can then stretch out of gas. These Further to description Carburettor spray can somewhat expensive filling method (for special cases) Usually omitted completely if a rubber membrane (after membrane spray can) is the spray material enveloped and shielded from external influences such as oxidation; Fig. "C". the The shape of the membrane and the pressure vessel is to be selected according to requirements and expediently. The known technical standards must be observed here.

Back to the atomization process. The carburetor medium "8" aims in the Spray head and must go through a strong taper there. It is according to the Fluid mechanics accelerated with a corresponding pressure reduction (negative pressure zone).

The simultaneously rising spray "9" is on the one hand by the light tension of the compressed air in the can expelled and thereby through pressed a nozzle-like taper. On the other hand, since the nozzle is open in the tapering of the carburetor media line opens out from the carburetor media flowing through sucked in, carried away, accelerated and very finely atomized than drier, more microfine Spray mist emitted (gasification medium-Sprtihgut.

Cemic).

It is important to ensure that the gasifier media volume for a complete Spray filling and emptying is sufficient. It should be borne in mind that the material to be sprayed It rises automatically into the carburetor area and strains the force of the filling Can interior air is returned. The carburetor medium is always fed up with sufficient The quantity of the product is loaded and does not have to perform any idle loads.

The carburetor spray can contains the sophisticated technology of the membrane spray can and proven components from carburetor technology and fluid mechanics in general.

The spray material is filled through the channels of the two-way double valve. The removal is done by pressing the spray head, with the same.

the discharge of the filling material and the gasification medium is triggered in good time will.

The movable filler and extraction nozzle on which the carburetor spray.

head tightly sufsteckt, are against the rest of the valve body Sealed on all sides by means of a sealing ring, a passage is only possible through the intended Recesses and channels possible. The closing movement of the valve connector is carried out by means of Helical spring is supported in a tried and tested manner (the specialist literature gives numerous Embodiments).

The space requirement ratio between the filling material and the gasification medium is around 1: 1. This depends on the design of the pressure capsule and its Storage capacity, as well as the passage cross-section of the gasifier and the uniform Load from product feed into the gasifier cup of the spray head.

The carburetor spray can can also be made of plastic in addition to metal Interior fittings are manufactured. The can walls basically only have moderate Withstand pressure loads. In this way a cheap packaging means is obtained for spray consumer goods and saves transport costs due to the lower weight of the can. The pressure capsule for the gasification medium should be filled by a specialist manufacturer delivered and then plugged in during the box assembly.

The carburetor zone of the spray head runs in a funnel-like extension the end.

The numerous designs and possible circuits for the The basic type of carburetor spray can allow an effective solution in each case.

The carburetor spray can is a fully-fledged solution to the aerosol question There is no longer the well-known destruction of the environment in the upper air layer and the impending long-term damage. The membrane spray can was already for most Spray tasks a sufficient solution and suitable as a replacement for the aerosol can, With the carburetor spray can, however, there are even more extensive and consistent ones Solutions. The aerosol spray can as such can be viewed as fundamentally removable will. However, this had already been done with the membrane spray can.

With both of the basic types of spray cans, the giver has real and effective ones Standard alternatives to the current, environmentally harmful spray can and industry a new, worthwhile product, which for an unlimited time without hesitation and for everyone desired spray products can be used without any environmental hazard. It can be like this It can be assumed that the previous concerns of the friends of outdated spray cans are irrelevant.

Something more about the technology of the membrane spray can or the carburetor spray can with product membrane. This type of can can be used in any posture, position and position will. Conventional cans have to be immersed in the riser tube in the contents of the can are kept more or less upright.

This fact applies to almost all aerosol cans. Keep falling the precautionary measures for aerosol cans with the carburetor spray cans away.

The Vrgaser spray can covers an urgent general need and leaves us the pleasant luxury of spray packaging with unadulterated joy.

The gasification medium in the pressure capsule can be compressed air or carbonic acid (e.g.) be. In any case, it has to be environmentally neutral or natural. It must either can be completely processed by the environment. Satisfied without a doubt Compressed air meets these requirements ok.
