Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a spray nozzle device used in various other liquid spraying machines such as pesticide sprayers and water sprinklers.

[Prior Art] In this type of conventional spray nozzle device,
Generally, devices with a sliding control knob that continuously sprays liquid such as agricultural chemicals are widely used, but it is difficult to perform operations such as switching when spraying is performed continuously or instantaneously. There is a drawback.

[Purpose of the invention] The purpose of the invention is to solve the above-mentioned drawbacks, to have a simple structure, to be able to arbitrarily select between continuous spraying and instantaneous spraying, and to easily perform the selection operation in one place. An object of the present invention is to provide a spray nozzle device which is convenient to handle and which can be easily handled.

[Summary of the invention] The gist of the invention to achieve the above objectives is as follows:
A nozzle part that sprays fluid, a valve body that opens and closes a fluid passage, and a roughly U that pulls the valve body in a direction to close it.
a leaf spring forming a letter shape, a sliding knob that pushes the top of the leaf spring by sliding and pushes the valve body back in the direction in which the passage opens, and a direction in which the top of the leaf spring is pushed in by being incorporated into the sliding knob. This is a spray nozzle device characterized by having a push button that moves independently.

[Embodiments of the invention] The invention will be described in detail based on illustrated embodiments.

1 to 3 show an embodiment of the spray nozzle device according to the present invention, FIG. 1 is a plan view, FIG. 2 is a sectional view when spraying is stopped, and FIG. 3 is a sectional view during spraying. It is a sectional view of the state. A valve block 2 is connected to the tip of the tubular base 1, and a hose 4 is connected to the rear end of the valve block 2, which has entered the inside of the base 1, for guiding the pressurized liquid to be sprayed through a hose connector 3. has been done. Inside the valve block 2, a rod-shaped valve element 6 that slides in the axial direction to open and close the valve seat 5 is provided, and the tip of the valve element 6 is approximately U-shaped.
One end of a tension type leaf spring 7, which exerts a force in the direction of closing the leg portion, is connected, and the other end of this leaf spring 7 is fixed to the valve block 2. Valve block 2 has
A sliding knob 8 for operation is provided to be slidable in the axial direction, and a push button 9 combined with the sliding knob 8 is arranged near the top of the leaf spring 7. This push button 9 is fitted to the sliding knob 8 so that it can move independently in a diametrical direction perpendicular to the sliding direction of the sliding knob 8, and slid together with the sliding knob 8 in the axial direction. There is. Also, inside the push button 9, there is a pressing surface 10 that presses the top of the leaf spring 7 when pushed in the diametrical direction, and a pressing surface 10 that presses down the top of the leaf spring 7 when the sliding knob 8 is slid together. A working taper surface 11 and a sliding pressing portion 12 following the tapered surface 11 are provided, and a protrusion 13 for preventing slippage is provided to prevent the tape from slipping out. In the embodiment, the leaf spring 7 is also used to prevent the push button 9 from coming out inward. Furthermore, 14 is a sealing gasket attached to the valve body 6 for closing the valve seat 5;
1 is a sealing ring for sealing the sliding part of the valve body 6; 16 is a fluid passage; 17 is a nozzle chip;
Reference numeral 8 indicates a fluid guide groove, and reference numeral 19 indicates a cap.

In the normal state when spraying is stopped, the sliding knob 8 is in a position where it has slid to the right as shown in FIG. The sealing gasket 1 attached to the valve body 6 is pressed to the left by the pressure of
4 closes the valve seat 5. In this state, the top of the leaf spring 7 is close to or lightly abuts the pressing surface 10 of the push button 9, so the leaf spring 7
is almost free.

When the sliding knob 8 is slid to the left from the state shown in FIG. 2, the sliding pressing portion 12 is moved as shown in FIG.
pushes the top of the leaf spring 7, so the leaf spring 7 is elastically deformed into an open state, and as a result, the valve body 6 moves to the right to open the flow path, and the sliding knob 8 is returned to its original position. The fluid continues to be sprayed from the nozzle tip 17 until the end. In this case, since the top of the leaf spring 7 is in contact with the flat part of the sliding pressing part 12,
Even if the finger is removed from the sliding knob 8, the sliding knob 8 will not be pushed back by the elastic force of the leaf spring 7.

In addition, in the state shown in Fig. 2 while spraying is stopped, press button 9.
When pushed inward, the pressing surface 10 is pressed against the leaf spring 7.
The valve body 6 moves to the right as shown in FIG. 3 and opens the flow path by pushing down the top of the leaf spring 7 to open the leaf spring 7. As shown in FIG. When the push button 9 is released, the elastic force of the leaf spring 7 causes the push button 9 to return to the state shown in FIG. Therefore, if the push button 9 is pressed and immediately released, instantaneous spraying can be performed.

In addition, in the above-mentioned embodiment, the case was shown in which the sliding pressing part 12 including the tapered surface 11 was provided on the push button 9.
As shown in FIG. 4, there is no problem in providing only the pressing surface 10 on the push button 9 and providing a sliding pressing portion 12a including a tapered surface 11a on the sliding knob 8 side.

[Effects of the invention] As explained above, in the spray nozzle device according to the invention, one operating sliding knob is combined with another push button that can be moved independently. You can choose whether to spray continuously or instantaneously, such as by sliding the sliding knob along with the push button, or by pressing and releasing the push button for an instantaneous spray. It is convenient to be able to select and operate from one place. In addition, since the component driven by the sliding knob that causes continuous spraying and the component driven by the push button are common, switching between them can be performed using a relatively simple mechanism. is possible.
