PURPOSE: To prevent environment pollution by providing a motor shaft with an eccentric ring which is under the effect of a cylinder spring and is connected to a slider. CONSTITUTION: The eccentric ring 2 and the cylinder spring 3 are connected to a single cylinder type pump 1. The eccentric ring 2 rotates by passing the motor shaft 5 ahead by a rotating angle of at least 120 deg. after passing over the max. point and the motor shaft 5 revolves continuously. Further, a switch 15 for turning on a drive motor 6 is provided and an air valve 16 is actuated as well. The air valve 16 is opened before the contact point of an electric switch is closed or simultaneously with turning on of the drive motor 6. The entire part of the vessel is aritightly closed to prohibit the outflow of the liquid 8 from a liquid chamber 17 under a presumed negative pressure. As a result, the environmental pollution is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a 1-hour atomization mechanism for liquid using a hydraulic pump.

BACKGROUND OF THE INVENTION Spraying mechanisms are generally already known in which a hydraulic pump mechanically actuated by finger pressure is employed to atomize a liquid in an atomizer (bottle or can). Known atomization mechanisms of this type have the disadvantage that the atomization only takes place when the fluid pressure generated in the pump chamber is sufficiently high, for example exceeding a value of about 6 to 8 bar. ing.

The spraying process is interrupted as soon as the minimum repulsive force in the pump chamber falls below. As a result of this, even though the user is continuously activating the activation button, there is no medium 1tfi jet stream from the spray nozzle.

OBJECT OF THE INVENTION The object of the invention is to create a spraying mechanism of the type mentioned at the outset in such a way that a jet stream is produced from the spray nozzle without or with little interruption, without problems of environmental pollution. .

(Means for Solving the Problems) According to the invention, this object is achieved in that the pump is driven by a drive motor or an electric motor with a transmission, and the motor shaft has an eccentric wheel, and the eccentric wheel is connected to the motor shaft. This is achieved by connecting a slider which is located at the working end of a Schilling spring and is connected to the piston of the pump. Advantageous embodiments of the invention are described in the subclaims.

(Embodiments) The present invention will be described in detail below with reference to embodiments shown in the drawings.

FIG. 1 shows a monocylindrical pump 1 to which an eccentric 2 and a Schilling spring 3 are connected.

In the case of a pump mechanism with this single pump 1, there is a short rest period between each injection, which is not unpleasant.

If the slider 4 is too large and rotates at high speed, the eccentric wheel 2
rotates the motor shaft 5 by at least 120° after passing the highest point.
It is designed so that the motor shaft 5 rotates continuously by a rotation angle of .

As shown in FIG. 2, the drive motor 6 is arranged vertically,
Therefore, it can also be placed parallel to the pump 1. In this system, a worm gear or bevel gear transmission 7 is used on the transmission side.

The advantage of operating with an eccentric 2 actuated by a drive motor 6 and a Schilling spring 3 is that the eccentric output bushing 14 is pushed downwards by the release of the Schilling spring 3 and the motor shaft 5 responds accordingly to the output of the drive motor 6. It is to be uniformly and continuously rotated. The opening of the Schilling spring 3 takes place whenever the eccentric wheel 2 exceeds its highest point in the vertical movement of the slider 4. This shilling spring 3
, the eccentric 2 overtakes the motor shaft 5 and the pumping process is immediately restarted, ie the suction pipe 10. is removed from the container 9. The extrusion of the liquid 8 via the discharge pipe 11 and the spray nozzle 12 is immediately resumed. Therefore, there is no need to wait for the eccentric wheel 2 to rotate half a rotation.

In theory this means that the eccentric 2 is moved downwards after passing the highest point on the slider 4, this movement being caused by the Schilling spring 3. The angle of rotation followed by the motor shaft 5 over the same time span is separated from its half revolution. That is, the opening of the Schilling spring 3 is actually performed when there is no self-locking of the eccentric output bush 14 within the slider slit 3 (see Fig. 5).
.

The actuation of the Schilling spring therefore generally provides a uniform atomization of liquid, as is normally done with propellant gases.

FIG. 1 further shows that the switch 15 for switching on the drive motor 6 simultaneously activates the air valve 16. This allows air to flow into the liquid chamber 17 of the container 9 by the amount of liquid discharged. Furthermore, the entire container must be absolutely gas-tight in order to prevent the liquid 8 from escaping from the liquid chamber 17 at the negative pressures envisaged, for example in an airplane. The air valve 16 is opened by the switch 15 before the contacts of the electric switch are closed or simultaneously with the switching on of the drive motor 6.

In the case of the dual pump arrangement in FIGS. 3 to 5, the spray nozzle 12 is preferably centrally located. The discharge and suction sides of both pumps 1, 1' are respectively connected to one another.

The drive is performed via the drive motor 6 which is supplied with power from the battery 18. Both pumps 1, 1' are connected to the piston 1
9 and 19' are in the neutral position and the double slider 21 is simultaneously in the zero position, they are arranged side by side and connected to each other in such a way that they each still have a minimum piston stroke for spraying.

This means that when the total stroke of the piston 19 is, for example, 6 mm, the first pump 1
It also has three suction rows CJ20 and a second pump 1
This means that the spraying stroke 20' of 3' or 3' is H. When the slider 21 compresses the piston 19 of the first pump 1, it is supported by the pump spring 22' of the second pump 1', so that the respective spring pressure is added or subtracted.

In the diagram of FIG. 4, the spring force P (symbol 23), the spring displacement pressure! S (24) and the piston ]9°19' neutral position 25. In the neutral position 25 the spring displacement distances S intersect in each case at half the displacement distance 26.

In the case of the spraying mechanism with two pumps 1 in FIG. 5, the drive takes place with a Schilling spring 3, but in the case of this double arrangement the time savings are somewhat less than in the case of a drive with two pumps. few.

By accelerating the eccentric wheel 2, a rotation angle of only approximately 120° is obtained.

In FIG. 5, it can be seen that the eccentric 2 reciprocates in the slit 13 of the slider 21 together with the eccentric output bush 14. Suction pipe 10.10 of pump 1, 1'
' are held together by holes in the pump housing 27, so that finally only one suction pipe 10 is present. The entire assembly consisting of pump, battery and electric motor is placed on the atomizer (bottle) in this manner.

In the mode of operation of the two pumps 1 in FIG. 5, the motor shaft 5 emerging from the battery-powered drive motor 6 is
The eccentric wheel 2 is driven via its drive shaft 28. In that case, the motor shaft 5 in FIGS. 1 and 2 is in the active position of the Schilling spring 3.

The eccentric wheel 2 has a slit 13 by its output bush 14.
The slider 21 is driven inside. This slider 21
The guide web 30 engages in the guide groove 29 of the pump storage housing 27. The guide web 30 extends at right angles to the slit 13 of the slider 21. Slit 13
Movement of the eccentric output bushing 14 within the guide groove 29 causes the slider 21 to reciprocate within the guide groove 29. This causes the pistons 19 and 19' of the pumps 1 and 1' to move to the slider 2.
The slider 21 and the pumps 1 and 1 are arranged so that the slider 21 and the pumps 1 and 1 are in neutral positions with respect to each other at the zero point positions of the pumps 1 and 1 (see FIG. 3).
A connection is made with the piston 19.19'.

In its neutral position, each piston 19.19' still has a stroke distance of 50% relative to the suction or discharge power of its pump 1.1'.

FIG. 6 shows a specific embodiment of the atomizer (bottle or can) 9. In FIG.

The atomizer 9 can be formed as a one-piece container or, as shown in FIG.
is present. Another attachment/detachment 6 instead of the screw connection 32
■A flexible connection method is also possible.

The housing 31 has a side wall opening 34 with a reservoir lid 35 in which a battery 36 is inserted or replaced.

This battery 36 is connected on the one hand to the drive motor 6 and on the other hand to the electrical switch 15 by a wire (not shown). A push rod 37 is attached to the electric switch 15 at the same time. This push rod 37 is connected to a spring-loaded air valve 38.
acts on The air valve 38 is fitted into a very thin air tube 39 with a diameter of about 2 to 5 mm. This air pipe 39 projects across the width of the container 33 for liquid 8 .

A reduction transmission device 40 that drives the eccentric wheel 2 on the output side is connected to the electric motor 6 . Its drive is performed by an electric motor shaft 5. This 7b drive shaft 5 is surrounded by a Schilling spring 3 which engages the output bush 41 of the eccentric 2 for rotational entrainment.

The eccentric output bushing 14 is connected to the slide 4 to 21 which follows the piston 19,19' of the piston pump 1.1'. The piston pumps 1, 1' have a suction pipe 10 and a housing 31 that protrude across the width of the container 33.
The discharge pipe 42, which opens into the spray nozzle 12 at the upper part thereof, is shown in white. The discharge outlet 42 has a spiral portion extending from the pump 1 to the spray nozzle 12 in a small number of turns (all 4 at an angle of 180°). As a result, the discharge pipe 42 does not bend over the axial movement of the pumps 1, 1', and a large lever length is obtained.

FIG. 7 shows a perspective view of the discharge tube 42 which extends over 360 degrees.

8 and 9 show a lower connecting pipe member 43 for the suction pipe 10 and an upper connecting pipe member 44 for the discharge pipe 42.
．． 4 schematically shows a piston pump 1 with 45; The connecting pipe member 44 is a screw! - It surrounds the tubes 19 and 19' and is bent by 90''. On the upper surface 46 of the connecting pipe member 44, there is a shaft or roller 47 that is moved up and down by a shaft 48 in accordance with the movement of the eccentric wheel 2. Existing (1 year old)

This ultimately causes the pistons 19, 19' to move synchronously.

Instead of acting directly by the roller 47, in FIG.
It can also be made to act. By connecting the free end of the lever 49 to the piston 1 .

The spiral portion of the discharge tube 42 allows the discharge tube 42 made of metal or synthetic resin to move at a rate of 200 to 300 times per minute of the piston 19.19'.
Allow some movement.

The arrangement of the air valve 38 in the switch 15 results in a very long air tube 39, the width of which is three air tubes with air present. The air column prevents the air from escaping even when the atomizer falls horizontally, thereby ensuring the introduction of air to compensate for the ejected atomizing liquid.

〔Effect of the invention〕

With the atomization mechanism according to the invention, firstly, no propellant gas is used to atomize the liquid, thereby avoiding environmental pollution problems. The drive system with an eccentric wheel actuated by a drive motor and one or more Schilling springs also has the advantage that a continuous jet stream can be generated when the switch is actuated during use of the atomizer. This occurs when the eccentric exceeds its highest point on the slider and the eccentric output bushing is pushed downward. In this case, the Schilling spring opens, but the output shaft of the drive motor continues to rotate uniformly and continuously. However, the opening of the eccentric toothed Schilling spring overtakes the motor shaft and the pumping process is immediately resumed without any appreciable interruption. This means making approximately half a turn downwards after the highest point on the eccentric or slider.

With the sprayer according to the invention, liquids and foams of different compositions can be dispensed for various purposes, e.g.
It can be sprayed in medical or household and industrial applications.
