Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a valve opening / closing device (mechanism) to be used by holding with a hand, that is, used for a hand-held liquid appliance. It is suitable for use as a valve for washing equipment for pedestals, sprinklers used in the garden, car washing equipment, equipment for showers used in bathrooms, seasoning liquid containers, and the like.

(Problems to be solved by the conventional technique and device) Conventionally, a water sprinkler having a valve that can be opened and closed by being operated at hand is known at the other end of a hose having one end attached to a faucet. .

For example, there is a hand-held sprinkler in which a portion for moving back and forth while rotating is provided in front of a main body held by hand, and the valve inside is opened and closed by rotating the portion and moving back and forth.

The sprinkler as described above has a disadvantage in that it is necessary to use both hands to open and close the valve, and thus it is inconvenient to use, and in some cases, the sprinkling work must be stopped.

A pistol-type water sprinkler has one or two hands holding the body.
The internal valve can be opened and closed by pulling the trigger lever with the fingers of the book or by loosening the pulling force.

The above is convenient because it can be operated with one hand and switching between opening and closing can be performed at a relatively high speed, but it has the disadvantages that the structure becomes complicated and expensive, and the bulk becomes large as a whole. Atsuta

The present invention solves the above-mentioned problems of the prior art, and can be operated with only one hand holding the main body, the valve can be opened and closed instantly with a weak force, and the gripping portion is the operating liquid. A technical problem is to provide a hand-held valve opening / closing device that does not come into contact with (contents), has a simple design, has a simple structure, and is inexpensive.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention forms a main body having an outlet in the front and an inlet in the rear by a front portion, a grip portion and a rear portion, and A valve seat and a valve body were provided inside, and a front portion having a valve push for separating the valve body from the valve seat and a rear portion having a valve seat were separated from the working liquid inside when radially expanded. The front portion and the rear portion are formed when a gripping portion is formed by connecting with a radial displacement member that mainly forms a thread-like member that forms a space and maintains a linear shape, and a gripping force is applied to the gripping portion. The valve seat and the valve body are moved away from each other to open the valve opening, and when the gripping force is weakened, the valve opening is closed.

The front portion and the valve push for separating the valve body from the valve seat are integrally connected, and the front portion and the rear portion forming the main body are generally brought close to each other when a gripping force is applied to the grip portion. To shorten the overall length of the main body, and the front portion and the valve push for separating the valve body from the valve seat are slidably connected to each other to form a front portion and a rear portion that constitute the main body. In some cases, when the gripping force is applied to the gripping portion, the gripping portion is partially moved closer to make the entire length of the main body constant.

(Operation) The present invention is configured as described above, and when water pressure or the like is applied from the inlet side, the valve body is pressed against the valve seat and the valve opening is closed, but the gripping portion is gripped. When the gripping force of the finger is increased, the radial displacement member is displaced inward in the radial direction, and the front portion of the main body with the valve push that separates the valve body from the valve seat and the rear portion with the valve seat. The valve seat and the valve body are separated from each other via the valve push, in whole or in part, so that the valve opening opens and water or the like flows from the inlet to the outlet.

In order to stop the flow, when the gripping force of the fingers holding the gripping portion is weakened, the valve body and the valve seat come close to each other due to water pressure, etc., and the front part and the rear part of the main body are entirely or partially And the radial displacement member is displaced outward in the radial direction to restore. At this time, since the inside of the grip portion is isolated from the working liquid, the grip portion does not come into contact with the working liquid such as water. In the restored state, the valve body is pressed against the valve seat by water pressure or the like to completely shut off the flow.
