Sprinkler

Abstract

A sprinkler head (1), comprising a sprinkler body (6) with a water flow path (10) formed therein, capable of being mounted on the sprinkler body (6) in an approachable and detachable manner The rod (15), the on-off valve (13) for opening and closing the flow path (10), has a fulcrum (17) rotatably supported on the spray head body (6), and a contact with the operating rod (15). Power point parts (18, 19) and the relay rod (16) of the action point part (20) abutted with the on-off valve (13), the relay rod (16) and the operating rod (15) and the nozzle main body (6) The positional relationship of the valve rotates correspondingly to open and close the on-off valve (13). Among them, two or more power point parts (18, 19) with different distances from the fulcrum part (17) are set on the relay rod (16). , at the water-stop position of the on-off valve (13), the point of force (18) formed farthest from the fulcrum (17) is abutted against the operating rod (15), and the opening ratio of the on-off valve (13) is At a position where the predetermined degree is large, another point of force (19) is brought into contact with the operating rod (15). According to the above configuration, in the sprinkler head, even in the state of high water pressure at the water stop position, the workload on the control lever can be reduced.

Description

technical field [0001] The present invention relates to a sprinkler head which is mainly used in gardening, cleaning, agriculture, etc. at home, and is connected to the front end of water supply equipment such as a water pipe through a hose to diffuse water, especially relates to a sprinkler head which is held in the user's hand and operated. Background technique [0002] In households, a sprinkler head that is attached to the tip of a hose and optionally switches between spraying and stopping water is widely used in gardening, agriculture, cleaning, and the like. Such a sprinkler head receives water supply from a water supply facility such as a water pipe through a hose, and sprays water from a sprinkler port formed at the front end. [0003] Previous sprinkler nozzles 25 such as Figure 8 As shown, a flow path 10 for water connecting the inlet port at the base end to the spray port 5a at the front end is formed in the shower head main body 6, and an opening and closing val...

AI Technical Summary

Problems solved by technology

[0020] However, in the sprinkler head of Patent Document 1, in order to reduce the operating load on the operating lever, the annular packing made of a special material, the E-ring for preventing the annular packing from coming off, and assembly processing are required. , therefore, material cost, manufacturing cost increase

[0021] In addition, when the water pressure of the water pipe is high, when the water is stopped, the valve core part of the second valve, which becomes the opening and closing valve core, is strongly trapped in the annular packing due to the hydraulic pressure, and the second valve is closed. When opening, a large force is required, and there is a problem that it is difficult to reduce the operating load of the operating lever.
