Description

[Detailed Description of the Invention] The present invention relates to a spray machine for spraying liquids, paints, etc., and particularly relates to an improvement in the strainer structure of the spray machine.

As shown in FIG. 6, this type of sprayer has a solenoid coil 2 housed in a housing 1, an armature 3 disposed in the solenoid coil 2, and a switch 5 disposed in a grip 4 vertically disposed on the housing 1. By the operation of the switch 5, an alternating current voltage is applied to the solenoid coil 2 to enable the armature 3 to reciprocate, and a cylinder 6 disposed on the front side of the housing 1 facing the direction of the reciprocating motion of the armature 3 is activated. The buried sleeve-shaped housing 1a is fixed to the housing 1 with a set screw 7.
A piston 8 is inserted into the cylinder 6, and a bullet 9 is inserted between the cylinder 6 and the piston 8.
By interposing the piston 8, it is possible to reciprocate within the cylinder 6 by cooperating with the end of the armature 3 due to the bombardment action of the ammunition 9, and a cover body 10 is formed on the lower side of the housing 1a. A container 11 for storing liquid, paint, etc. is suspended, and a suction hole 12 and a discharge hole 13 are formed in the housing 1a, the lid 10, and the cylinder 6 to communicate the inside of the cylinder 6 and the container 11, Insert the upper end of the suction pipe 14 into the suction hole 12 of the lid 10, and
A strainer 15 is disposed at the lower end of the pipe. Also, a valve 16 and a bullet 17 are provided on the front side of the housing 1a.
and a nozzle holder 19 with the nozzle 18 placed therein.
A housing 1b that covers the solenoid coil 2, armature 3, etc. is fixed to the housing 1 with screws 20, and the housing 1b receives spray from a nozzle 18 by adjusting the reciprocating distance of the armature 3. An adjustment knob 21 is provided to adjust the state of mist of liquid, paint, etc.

Therefore, the liquid, paint, etc. in the container 11 passes through the suction pipe 14 due to the pump action of the suction/compression process generated by the reciprocating movement of the armature 3 and the piston 8 associated with the solenoid coil 2 and the bullet 9. is sucked into the cylinder 6, and along with the compression operation of the piston 8, the valve 16 opens the open end 6a of the cylinder 6 against the force of the bullet 17, and the open end 6a
The water passes through the nozzle 18 and is sprayed from the ejection hole 18a of the nozzle 18.

However, if the ejection hole 18a of the nozzle 18 becomes clogged, if liquid or paint adheres between the piston 8 and the cylinder 6, or if the strainer 15 becomes clogged, the spray condition will deteriorate. Each part must be disassembled and cleaned. In that case, the conventional strainer 15 has a flange portion 14a formed at the lower part of the suction pipe 14,
A strainer 15 is detachably formed on this flange portion 14a. Therefore, the strainer 15 may sometimes come off the flange portion 14a during the spraying operation, and the filtering function of the strainer 15 may not be achieved. In addition, the strainer 15 was easily lost during disassembly and cleaning.

In view of the above-mentioned circumstances, the present invention provides a sprayer equipped with a strainer structure that can solve the problem of the strainer falling off or being lost.The present invention is characterized by the fact that the liquid contained in the container is inserted into the suction pipe. In a device that sucks up liquid from a suction port through a strainer by a pump action and sprays the sucked up liquid from a nozzle, the strainer part arranged surrounding the suction port of the suction pipe and the suction pipe side are connected by a hinge part. It's what I did.

Next, a first embodiment of the present invention will be described with reference to FIGS. 1 to 3. Reference numeral 31 denotes a housing housing a solenoid coil 32, and an armature 33 is disposed in the solenoid coil 32.
34 is a grip installed vertically on the housing 31, and is provided with a switch 35. The solenoid coil 3 is activated by the operation of the switch 35.
By applying an alternating current voltage to the armature 33, the armature 33 can be moved back and forth. 31
A is a sleeve-shaped housing fixed to the front side of the housing 31 with a set screw 36, and a cylinder 37 is disposed in the front-rear direction. A piston 38 is inserted through the cylinder 37, and a bullet 39 is interposed between the cylinder 37 and the piston 38, and the bullet 39 moves in conjunction with the end 33a of the armature 33. A piston 38 is formed within the cylinder 37 so as to be able to reciprocate. Reference numeral 40 denotes a lid integrally formed on the lower end side of the housing 31a, and a container 41 for storing liquid, paint, etc. is suspended by a threaded portion 42. 43 is a suction hole formed in the housing 31a, the lid 40, and the cylinder 37; 44 is a discharge hole similarly formed;
The upper end of the suction pipe 45 is inserted into the suction pipe 45, and a strainer 46 is arranged so as to surround the suction port 45a of the suction pipe 45. Reference numeral 47 indicates a valve 48, a bullet 49, and a nozzle 5 disposed on the tip side of the housing 31a.
This is a nozzle holder for fixing the housing 31a, and is screwed onto the tip of the housing 31a. 31b is a housing that covers the solenoid coil 32, armature 33, etc., and is fixed to the housing 31 with screws 51. Reference numeral 52 denotes an adjustment knob disposed on the housing 31b, which allows adjustment of the reciprocating distance of the armature 33. Therefore, due to the suction/compression process generated by the reciprocating movement of the armature 33 and the piston 38 associated with the solenoid coil 32 and the bullet 49, the liquid, paint, etc. in the container 41 passes through the suction pipe 45 and into the cylinder 3.
7, and as the piston 38 compresses, the valve 48 resists the force of the bullet 49 and compresses the cylinder 3.
7 is opened, the liquid passes through the open end 53 and is sprayed from the injection hole 54 of the nozzle 50.

By the way, the strainer 46 of the first embodiment is
As shown in FIG. 3, a flange portion 45b is integrally formed at the lower part of the suction pipe 45, and a strainer 46 surrounding the suction port 45a at the lower end of the suction pipe 45 is provided at one end of the flange portion 45b. Hinge part 55

is surrounded by a strainer 46. In that case,
Suction pipe 45, flange portion 45b, and strainer 46
It is preferable that these are integrally molded from synthetic resin, and the hinge portion 55 may be formed from a thin portion. Alternatively, the strainer 46 may be formed by integrally molding only the frame 46a with the suction pipe 45 side and the hinge portion 55, and insert-molding the mesh body 46b made of synthetic resin or metal separately later. Therefore, when the container 41 is removed from the lid body 40 or the suction pipe 45 is removed from the suction hole 43 during disassembly and cleaning work, there is no fear that the strainer 46 will fall into the liquid or paint. 46 is never lost. Also, strainer 46
