Description

[Detailed description of the invention] The present invention relates to an improved structure of a sprayer that sprays atomized liquid from a nozzle using a pump action. In general, this type of sprayer is functionally efficient without complicating the components. There is a desire to facilitate the assembly and disassembly of the device by forming it, thereby simplifying its handling.

In other words, when using the above-mentioned sprayer for painting, etc., if you do not clean it every time you use it, the spray path will become clogged due to paint drying and adhesion, inhibiting the spraying effect, so make sure it is easy to clean. It is desirable that the device can be easily attached and detached.

By the way, in a conventional sprayer, as shown in the first diagram, an armature 3 is disposed on a solenoid coil 2 housed in a main body 1 to form an electromagnetic device, and a switch 5 is attached to a grip 4 that extends downwardly from the main body 1. A housing 6 protrudingly provided to apply an alternating voltage to the coil 2 enables the armature 3 to reciprocate in an arc with its upper part as a fulcrum, and extends integrally with the main body 1 and in a direction orthogonal to the grip 4. The cylinder 7 is screwed and fixed with screws 8, one end of the piston 9 is brought into contact with the armature 3 in the longitudinal direction of the main body 1 and the housing 6, and the other end of the piston 9 is inserted and supported in the cylinder 7. 7 and the piston 9, the piston 9 can reciprocate within the cylinder 7 by cooperating with the armature 3 due to the elastic action of the spring 10, and the lid 11 is integrated with the main body 1. A container 12 for storing liquid paint or the like is screwed and suspended, an inlet 13 and an outlet 14 are formed from the cylinder 7 to the container 12, and a valve acts on the free end of the housing 6. The valve cone 15 is attached to the cylinder 7 by the elastic action of the spring 160.
The nozzle 1 is formed on the starting end side of the housing 6.
In addition, a suction pipe 18 is inserted into the suction port 13, and the suction pipe 18 is screwed into the suction port 13.
is introduced into the container 12, and a filter 19 for filtration with a fine mesh is attached to the tip of the suction pipe 18.

Further, a liquid part 12a is formed protruding from the bottom of the container 12, and a filter 19 attached to the tip of the suction pipe 18 led into the container 12 is disposed within the liquid part 12a. .

Note that 20 indicates a cap that protrudes from the bottom of the container 12 and covers the liquid reservoir 12a.

As configured above, the paint sprayed by the reciprocating motion of the armature 3 and the piston 9 by the solenoid coil 2 and the spring 10, that is, the suction and compression stroke of the piston 9 within the cylinder 7, passes from the container 12 through the suction pipe 18 and enters the cylinder. As the paint shrinks, the valve cone 15, which is tightly attached to the tip of the cylinder T, resists the force of the spring 16 and separates from the cylinder 7, and the paint is injected from the small gap. Furthermore, it is formed so as to spray through a nozzle 17.

In addition, when cleaning each part during maintenance and inspection of the sprayer, and to wash away paint that has adhered to the paint distribution route and spray route, water is generally used for water-based paints, and thinner is used for oil-based paints. By putting water or thinner into the container 12 and spraying it, paint adhering to each path is washed away, and each part can be cleaned.

By the way, when using paints of different colors one after another, it is necessary to remove the paints adhering to the distribution route and spray route of the sprayer.
After removing the container 12 screwed and suspended from the container 12 and cleaning the container 12, each part must be cleaned as described above, and the container 12 must be removed and reinstalled many times. If the lid 11 and the container 12 are not screwed together until the lid 11 and the container 12 are in close contact with each other, the lid may be damaged when the sprayer is used with the main body 1 tilted during the spraying operation. There is a problem in that paint leaks from the gap between the screwed together portion of the body 11 and the container 12.

Therefore, the container 12 must be securely screwed onto the lid 11, but since the container 12 is relatively thick, it is difficult to turn it, and there is a risk of accidentally dropping the container 12 and spilling the paint. Attaching or removing the container 12 is troublesome.

Furthermore, even when spraying is used with the direction tilted vertically, the paint flows under its own weight into the liquid reservoir 12a formed at the bottom of the container 12 as shown by the arrow, and the paint filled in the container 12 is The liquid can be sucked up from the suction pipe 18 and sprayed until the amount of liquid becomes extremely small, making it economical.

Even if the bottom side of the liquid puddle 12a formed at the bottom of the container 12 is touched to the ground when the sprayer is placed, the contact area is small, resulting in an unstable situation and the sprayer falling over, damaging parts of the sprayer. There is a problem with this.

In order to solve this problem, the cap 20 is generally fitted onto the bottom of the container 12 from the lower side of the liquid reservoir 12a to widen the ground contact area and maintain stability.

However, there is a drawback that the cap 20 must be formed separately from the container 12, which increases the number of parts and makes the assembly work cumbersome and complicated.

The present invention is intended to solve the above-mentioned problems, and aims to simplify the maintenance and management of the device and its handling during work.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3, using some of the structural members shown in the prior art.

In the same figure, a container 12 screwed and suspended from a lid 11 formed on the main body 1 side of the sprayer has a liquid reservoir 12a protruding from the bottom surface of the container 12, and a liquid reservoir 12a is formed at the periphery of the liquid reservoir 12a. A plurality of ribs 12b are integrally provided to protrude from the bottom surface of the container 12.

Further, the rib 12b is set at a height that is the same as the bottom surface of the liquid reservoir 12a or slightly protrudes from the bottom surface of the liquid reservoir 12a.

As in the above structure, by forming a plurality of riffs 1.2b on the container 12, after rinsing paint etc. into the container 12 when using the sprayer, the lid body 1.2b formed on the container 12 and the main body 1 side can be removed. The container 12 can be screwed onto the lid 11 and suspended by hooking a finger onto the rib 12b formed on the bottom of the container 12 or by turning it with the palm of the hand. As a result, the rib 12b formed integrally with the container 12 can serve as a non-slip member, and can be easily and reliably screwed onto the lid 11 of the sprayer main body 1.

Further, the rib 1 is formed so that it is flush with or slightly protrudes from the bottom surface of the liquid reservoir 12a formed by protruding from the bottom surface of the container 12.
By setting the height of the container 12, the height of the container 12 can be set so that the container 12 can be placed on the ground. , there is no fear that the sprayer will fall over and cause damage to parts, the cap 20 that covers the liquid reservoir 12a formed in the container 12 is also unnecessary, the sprayer can be placed in a stable state, and the number of parts is reduced. It is possible to construct a container structure for a sprayer that is easy to handle and requires less.
