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.

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

Embodiments of the present invention will be described below with reference to the accompanying drawings.
In the figure, 1 is a sprayer, for example an aerosol sprayer, and 2 is an operating lever. The sprayer 1 has a container, that is, a housing 3, which contains a liquid and a cylinder of liquefied gas for increasing the internal pressure, and a stem 4 for delivering the pressurized liquid.
The stem 4 projects upward through a valve, and a spray head 6 having a nozzle hole 5 is attached to the upper end of the stem 4 . That is, when the spray head 6 is pushed down,
During the depression, pressurized liquid is ejected from the nozzle hole 5 in the form of a mist. Note that the top surface of the spray head 6 is the nozzle hole 5.
The top wall member 7 of the housing 3 is provided with a groove 8 for fitting around the circumferential wall thereof.

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 supporting 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 fitted with an inwardly facing part. A service protrusion 14 is provided around the circumference, and this protrusion 1
The operating lever 2 is attached to the sprayer 1 by fitting the lever 4 into the fitting groove 8 of the sprayer.
At this time, the outer cylinder 15 hanging downward from the inner cylinder 13 fits into the stepped portion at the upper part of the sprayer housing 3 to stabilize the attachment. Note that a portion of the inner cylinder 13 in the circumferential direction is cut off to facilitate attachment and detachment. 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 grip operation part 19 and a horizontal driving part 20, and the downward tip of the driving part 20 is close to the middle part of the slope of the top wall of the spray head 6 from above. The finger-operating section 19 is located in the window 16 of the grip section 11, the rear half of the drive section 20 is located at the window 17 of the mounting section 12, and the lever body 10 is supported at a substantially central location 21 of the finger-operating section 19. It is pivotally supported by the wall of the fixed part 9.

In the above configuration, in order to operate the spray, grasp the grip part 11 of the support fixing part 9 with one hand, hook the index finger of the gripped hand onto the finger hook operation part 19, and move this operation part 19 in the near 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 section 20 moves forward, so that the downward tip of the drive section 20 comes into sliding contact with the top slope I of the spray head 6. is pushed downward, so the pressurized liquid is sprayed from the nozzle hole 5 and is injected outward through the window 18.

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 1. Therefore, the grip part 11 can be made into the size and shape that are most easy to grip regardless of the size and shape of the sprayer 1. Therefore, supporting the sprayer 1 and spraying operation can be made convenient and easy. In addition, the shape is an inverted L shape as described above, and the grip part 11 is parallel to the sprayer container 3, so the operating lever 2
Since the area occupied by the mounting 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. Furthermore, since the finger-operating portion 19 of the lever body 10 is disposed inside the grip portion 11, it is safe to prevent spray from being inadvertently ejected. Also lever body 10
Since the drive unit 20 moves in the lateral direction, no force is applied to the lever body 10, and it also slides on the top slope of the spray head 6 to move it downward. This has the advantage that reliable operation can be expected without giving any shock to the sprayer. 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, but can also be applied to a manual sprayer.

[Scope of utility model registration request] The top surface of the spray head 6 of the sprayer 1, which is the object to be attached, has a slope that rises as it goes toward the nozzle hole 5 side. The support fixing part 9 of the formed cylindrical body, the vertical finger hook operation part 19 and the horizontal drive part 20 form an inverted L shape, and the operation part 1
9, the lever body 10 is installed in the supporting and fixing part 9, and the tip of the driving part 20 moves forward when the operating part 19 is pulled. A downward fitting protrusion 14 is provided for attachment to the mounting portion 12, and a window 18 is provided on the wall surface facing the nozzle hole 5 at the tip of this attachment portion 12.
In addition, windows 16 are formed on the inner wall surface of the gripping part 11, respectively.
This is an operating lever for a sprayer in which the finger-operating section 19 of the lever body 10 is located in the window 16, and the downward tip of the driving section 20 is disposed close to the midway point of the top slope of the spray head 6.
