Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a time-limited sprayer for insecticides, etc., which starts spraying after an appropriate time after starting operation.

``Prior Art'' For example, insecticide sprayers for cockroaches and the like are of the so-called aerosol type, in which the room to be sprayed is closed off, and when started, the insecticide is sprayed like smoke, filling the room. There are two types of starting methods for this sprayer: a general type in which a nozzle with a protruding top is pushed in, and a tilt tamp type in which the nozzle is tilted sideways.

``Problem that the invention aims to solve'' When a sprayer is started, it immediately opens and sprays its contents, so in the case of insecticides, the sprayer must be evacuated outdoors immediately after starting, making it difficult to use.

The object of the present invention is to provide an easy-to-use time-limited sprayer that is of the tilt type and starts spraying after an appropriate time after starting operation.

"Means for Solving the Problems" The time-limited sprayer of the present invention has a large outer diameter section 4a at the lower part of the nozzle 4 protruding from the top, and the nozzle 4
The atomizer main body 1 injects the liquid content from the nozzle 4 when tilted, and the top wall 5 has an injection window 6 in the inclination range of the nozzle 4, and one side from the rear of the top wall 5 to the peripheral wall 7 is pressed. A receiving plate 9 formed on the button 8 and having a rough inner surface is provided inside the front side, and guide plates 10, 10 facing left and right are vertically provided from the top wall 5, and these guide plates 10, 10 are on the face,
A cap 2 is attached to the top of the sprayer main body 1 by symmetrically forming dogleg-shaped guide grooves 11, 11 for an outward path diagonally forward and downward and a backward path diagonally backward and downward, and the inner surface is attached to the upper small diameter of the nozzle 4. A frame 13 is attached to the front outer surface of the frame 13, which is provided with pins 12, 12 protruding from both the left and right sides, which surround the outer circumference of the nozzle 4 and which engage with the guide grooves 11, 11 from both the left and right sides. It has a bowl-shaped suction plate 15 that swings freely in contact with the rough surface of the receiving plate 9, and when pushed to the front side by the push button 8, the suction plate 15 moves forward along the outward path of the guide grooves 11 and 11. After the scheduled time limit, this suction plate 15
When restored, the nozzle 4 is returned to its original position via the return path of the guide grooves 11, 11, and the front part of the frame 13 pushes the nozzle 4 through the large outer diameter part 4a to tilt the nozzle 4.

"Function" In the above, at all times before the starting operation, the pins 12, 12 of the frame 13 of the time limit mechanism 3 are at the starting points of the guide grooves 11, 11 in FIG.
is inclined rearward and upward as shown in FIGS. 1 and 2 a, its rear part contacts the push button 8, its front inner surface contacts the upper small diameter part of the nozzle 4, and the suction plate 15 on the front outer surface is in contact with the receiving plate 9.

Here, in use, the push button 8 may be pushed inward. Then, the frame 13 is inserted into the guide grooves 11, 11.
When the pins 12, 12 reach the turning point of the guide grooves 11, 11, the suction plate 15 is compressed to the maximum extent. This turning point is approximately at the upper end position of the large outer diameter portion 4a of the nozzle, and at this point the frame 13 descends diagonally backward and downward.
Then, the suction plate 15 gradually restores its original state by sucking in air through the rough surface of the receiving plate 9, and its restoring force pushes the frame 13 back. In this case, the frame 13 has guide grooves 11,1
1, the suction plate 15 is returned after the scheduled time limit.
When the frame 13 is almost fully restored, the front part of the frame 13 is lowered and the nozzle 4 is pushed in through the large outer diameter part 4a, and the nozzle 4 is tilted as shown in FIG. 2b to inject the liquid inside.

``Example'' The aerosol type spray container main body 1 is very well known, and the present invention does not relate to this sprayer main body 1 itself, so to briefly explain, this sprayer main body 1 contains, for example, a liquid insecticide. A cylinder of liquefied gas or the like is built into the can container body 16 to increase the internal pressure, and when the nozzle 4 is tilted at a certain angle, the discharge valve opens and the liquid inside is released from the nozzle 4 in the form of smoke. Inject. The large outer diameter portion 4a of the nozzle 4 can be easily formed by fitting a separate cylindrical body whose lower half has a larger outer diameter to the protruding nozzle.

The push button 8 of the cap 2 is arranged at the rear so as to form a part of the top wall 5 and the peripheral wall 7, and its lower end is connected to the peripheral wall 7 with a flexible hinge 17 so that it can be pushed in. Push plates 18, 18 are provided. This cap 2 is attached by forcefully pushing the lower end of the peripheral wall 7 into engagement with the engagement protrusion 19 on the top of the can container body 16 of the sprayer main body 1. The dogleg-shaped guide grooves 11 and 11 are grooves of the same depth, but in the middle between the starting point near the turning point and the turning point, the starting point side is gently inclined, and the turning point side is almost vertical. A protrusion 20 having a serrated cross section is provided, and the pins 12, 12 are formed so that they always follow the →→ route and never return to the starting point.

The frame 13 of the timing mechanism 3 has a square frame shape, and a catch 21 is provided on the front side via a flexible hinge 14. By grasping the boss 22 of the suction plate 15 with this catch 21, the suction plate 15 can be moved up and down. Connected so that they can swing. The pins 12, 12 are provided near the front of the frame 13, so that when the suction plate 15 is pushed in, it comes off from the push button 8 that supports it and naturally descends diagonally backward and downward using the flexible hinge 14 as a fulcrum. It is set as.

The time limit of the time limit mechanism can be set as required by finely or roughly adjusting the rough surface of the receiving plate 9. In addition, each of the above parts is molded and manufactured from synthetic resin material.

"Effect of the invention" As mentioned above, in this invention, the timer mechanism 3 is provided,
This timing mechanism 3 causes the sprayer body 1 to spray after a required time period after the starting operation.
It is easy and convenient to use when spraying insecticides. Further, the operation is simple and requires no trouble at all, simply by pressing the push button 8. Further, the push button 8 is formed by a part of the cap 2, and the time limit mechanism 3 includes a frame 13 surrounding the nozzle 4, a suction plate 15 on the front side of this frame 13, and a guide that guides the frame 13 along a predetermined path. It has a simple structure combining the grooves 11, 11, and since the timing mechanism 3 is installed inside the cap 2, it does not impair the appearance or design.
