Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control lever for a sprayer that is detachably attached to the sprayer and drives the spray head.

As is well known in the art of atomizers, such as aerosol atomizers, a liquefied gas cylinder is built into a casing containing a liquid, and the internal pressure is increased by the pressure of the liquefied gas. Open the valve by lowering the valve, etc.
This device sprays pressurized liquid while the spray head is pressed down, and is widely used. In other words, this type of sprayer is operated by grasping the casing, that is, the container body, with one hand, and pressing the spray head with the index finger of that grasped hand, but the sprayer is large. When this happens, it becomes insufficient to hold it with one hand, and it is also difficult to place a finger on the spray head, making spraying operations inconvenient.

The object of the present invention is to provide an operating lever for a sprayer that can be detachably attached to a sprayer, can easily support the sprayer regardless of its size, and can easily drive the spray head.

The first embodiment will be explained below with reference to the attached FIG. In the figure, 1 is a sprayer, for example an aerosol sprayer,
2 is an operating lever. The sprayer 1 has a container, that is, a housing 3, containing a liquid and a cylinder of liquefied gas for increasing internal pressure, and a stem 4 for delivering the pressurized liquid projects upward through a valve. A spray head 6 having a nozzle hole 5 is installed. That is, when the spray head 6 is pushed down, pressurized liquid is sprayed out from the nozzle hole 5 during the depression. Incidentally, a fitting groove 8 is provided around the peripheral wall of the top wall member 7 of the casing 3.

Next, the operating lever 2 includes a supporting and fixing part 9 formed from a cylindrical body whose overall shape is approximately an inverted L shape, and a lever body 10 that is pivotally mounted in the supporting and fixing part 9. The support and fixing part 9 consists of a vertical grip part 11 and a horizontal mounting part 12, the tip of the mounting part 12 is formed into a downward double cylinder, and the lower end of the inner cylinder 13 is for inward fitting. A protrusion 14 is provided around the circumference, and this protrusion 14
The operating lever 2 is attached to the sprayer 1 by fitting it into the fitting groove 8 of the sprayer, and at this time, the outer cylinder 15 hanging down from the inner cylinder 13 is attached to the upper part of the sprayer housing 3. Fits into the stepped part to stabilize the installation. Incidentally, a portion of the inner cylinder 13 in the circumferential direction is cut off to facilitate installation and removal. The upper inner wall of the gripping part 11 and the rear upper wall of the mounting part 12 are cut out to form windows 16 and 17, respectively, and a window 18 is also formed in the downward cylindrical wall facing the nozzle hole 5 of the spray head 6. There is.

The lever body 10 has a substantially inverted L shape corresponding to the support fixing part 9.
It has a letter-shaped shape and consists of a vertical finger operating section 19 and a horizontal driving section 20, and the downward tip of the driving section 20 faces the top surface of the spray head 6 closely from above, 19 is the grip part 11
The rear part of the driving part 20 is located in the window 16 of the mounting part 12, and both parts 19,
It is pivotally supported on the wall of the support fixing part 9 at two places 21 and 22 of the support fixing part 20. Incidentally, the bending point A has a flexible bending degree structure.

In the above configuration, in order to operate the spray, grip the grip part 11 of the support fixing part 19 with one hand, hang the index finger of the gripped hand on the finger grip operation part 19, and move the finger grip operation part 19 in the forward direction, that is, in the direction of the arrow. Just pull it to the right as shown in the figure. Then, the lever body 10 is displaced as shown by the broken line, and the drive unit 20 is thereby displaced.
The tip moves downward and pushes down the spray head 6, so the pressurized liquid is sprayed from the nozzle hole 5,
It is emitted outward through the window 18.

FIG. 2 shows a second embodiment. In the first embodiment, the lever body 10 was of an integral structure, but in this embodiment, the drive 20 of the lever body 10 and the finger grip operation part 19 are separate bodies, and the two are brought into contact with each other at their end surfaces. The same operation and effect as the first embodiment can be expected.

As described above, in the present invention, the operating lever 2 is composed of an inverted L-shaped supporting and fixing part 9 and a lever body 10 of approximately the same shape that is pivotally supported inside the supporting and fixing part 9,
The support fixing part 9 has a grip part 11 in the vertical direction parallel to the casing 3 of the sprayer, that is, the container body, and is fitted and attached to the upper end of the sprayer container at the horizontal mounting part 12.
On the other hand, the finger operation part 19 of the lever body 10 is connected to the grip part 1.
1 is arranged in the grip part 11 so that it can be operated with the fingers of one hand gripping the sprayer.
The shape is inverted L-shape as described above, and the grip part 11 is parallel to the atomizer container, so that the operation lever can be easily supported and sprayed. Since the area occupied by the lever 2 is relatively small, it does not interfere with other objects, and since the operating lever 2 is detachable, it is convenient for transportation, packaging, and storage. Also lever body 1
Since the finger-operating section 19 of 0 is disposed inside the grip section 11, it is safe to prevent the spray from being inadvertently ejected. In the above embodiments, an aerosol sprayer was used as an example of the sprayer, but the sprayer is not limited to an aerosol type, and may be a manual sprayer.
