Description

♦ Hand-operated atomizer device ¹ *

Various atomizer ducts of this type are known which, however, have the roof part, since there are generally many structural parts and, as a result, high ones Require manufacturing costs.

According to the invention, these compartment parts are avoided by a hand-operated atomizing device which is characterized by a body which is old a cylinder an Ilalass device with input of atomization equipment into the cylinder from a source via a first Has a shut-off valve and a shaft area soldered by the hand of an operator, through a piston

member, the inner end of which is displaceable tightly in the cylinder and which has a passage opening made therein, with a second shut-off valve for outwardly guiding the atomizing material flow through the passage opening and with a device at its outer end for spraying the atomizing material through the passage opening, by a spring device which urges the piston outwardly with respect to the cylinder and a handle device which is adapted to be actuated by the fingers of an operator to reciprocate the piston through the cylinder against or by the force of the spring device leaves.

An advantageous development of the invention consists in the fact that the first and / or the wide shut-off valve consists of a one-piece, resilient element of hat shape with a truncated conical or partially spherical cap area and is provided with one or more incisions in the cap area _? which are designed in such a way that they are open when a higher pressure is present on the inside of the cap area than on its outside, and that they are closed in the opposite condition ο

The invention will now be explained in more detail with reference to drawings. Show it:

FIG. 5 is a plan view of the valve according to FIG. 4.

The atomizing device according to the invention shown in FIG. 1 has a. Body 11 having a cylinder 12 * which is provided with a Innenansats 13 'em the closed end of the cylinder starts 12th The body 11 also includes a zy indrischen Schaftbereieh 14 which protrudes from the cylinder 12 to _s at approximately right angles to the axis thereof, and a cantilever portion 15 extending in the opposite direction as the field Creates fourteenth It is permissible for the cantilever area 15 and the shaft area 14 to be molded as a unitary body from plastic (e.g. Ä.B, S _u -plastik). In the shaft area 14, an inlet bore or an inlet passage 16 for the cylinder 12 and a bore 17 of larger diarchaeuses are provided, which are arranged coaxially with the shaft area 14.

In the wide bore 17 is a hat-shaped member 18 bait a flange 19 and a central tubular area tightly fitted, which are uniformly made of flexible "material" like ZoB. (Jumrai or the like, are formed so that the Rohrföraige area 20 under airtightness ait des Inlet flow 16 communicates. In addition, the tubular area 20 is an intermediate wall 21 with a central one

209816/080 3

Flow of 22 as a valve seat _S is used as well as a projection 23 'which is slightly offset from the Sitfsoberfläehe the wall 21 is provided j ,.

A sleeve 24 is fitted in the 3-eared area 20 and lie; with its outer end on the projection 23. A $ eil 25! bit reeiiteckföraiigeis cross section is in the power seat in the Sleeve 24 fitted so that four-crescent-shaped spaces may be formed between the sleeve 24 and the part 25, as in Pig. 3 shown. In the small by the wall 21 that Bushing 24 and the rope 25 certain chamber is rectangular Valve plate 26 is arranged with its own weight on the seat surface of the wall 21, which works as a shut-off valve «

A flexible tube 27 of the appropriate length is inserted into the outer end of the tubular area 20 in the eraftsits. To connect the atomizer, use an ordinary hook 28 with a visual opening; which contains spray material »is a connector 29 provided at the outer end of the shaft area 14. The connector 29 is ring-shaped and has a screw thread 30 to be brought into engagement with the bottle opening and an inner flange 31 _? which is designed in such a way that the splash 19 of the link 18 is caused to lie tightly against the face end of the bottle opening.

Ψ A piston 32 according to the invention comprises a piston body 33 made of plastic fcann (ss.B _o AB "p-Plastic) · This Kölbeßkörper 35 has at its inner end a lug 34 fiiit same diameter as the approach previously described 13 of the cylinder 12 as well as a through-bore or a through-flow opening 35 including a bore 36 "with a wide diameter but small length" which is formed on the outside of the bore 35, aa inner end of the piston body 33

209816/0803

is a piston ring 37 made of a flexible material such as rubber or the like provided ^ eggs, as will be explained later, has a "special design shown in the Uyghur," to include the announcement area of the approach 34, where a peder is held.

At the end of the larger bore 36 of the piston body 33, a second shut-off valve 38 is arranged, which consists of a one-piece, flexible element made of rubber or the like and has an overall hat shape partially spherical shape and one or more (sx ^ ei in the Pigur) notches 41, which extend through the center of the cap area 40 and have a depth sufficient to closely approach the PuS of the cap 40 through the wall of the cap 40. Some ribs 42 may be provided on the cap region 40 for reinforcement. As can be seen from this, the valve 38 opens the incisions 41 $ when a higher pressure is present on the inside of the cap area 40 & 1 & on the outside thereof, and closes the incisions 41? if the condition is reversed c,

At the outer end of the piston body 33 an atomization cartridge 43 is provided * which is made of plastic, e.g. Polyethylene, is shaped. The atomization cartridge 43 has a head 44 with two parallel flows 45 and one Overflow canal 46 for the two Ichrivers 45 and the same a tubular area 4? on. The cartridge 43 is with its tubular area 47 in the bore 36 of the Piston body 33 recessed to cause the end of the tubular portion 47 to rest on the surface 36 of the valve 38, which is secured by an annular retainer 48 is held, which is the outer end of the piston body

209816/0803

in engagement with an annular seal 49 by screw threads brings. The line 49 is between the cartridge 43 and the outer end face of the basket body 33 is arranged.

While the piston 32 is fitted in the cylinder 12 through the piston ring 37 in the cylinder 12, a pressure cap of the 50 "as shown in FIG. 1" is arranged in the cylinder 12 in such a way that it encompasses the projections 13 and 34. Their ends lie on one side at the closed end of the cylinder 12 and on the other hand at the shoulder of the piston ring 37 at ₅ , the piston 32 being pressed outwards.

The cylinder 12 is used to move the piston 32 back and forth a lever handle 51 is provided which is attached to the pivot area 15 of the body 11 is hinged at the point 52 * The free The end of the lever handle is essentially parallel to the shaft area 14 of the body 11 is oriented to be operated by the operator's fingers. The lever handle 51 has a longitudinal opening 53 in an intermediate area, through which the piston body 33 works freely. On both A pair of stops 54 is provided on the sides of the opening 53, each slidably seated on a pair of pin-like lugs 55 on the piston body 33 *
