Description

Multifunctional water gun with hook trigger

Technical Field

The utility model relates to a control method of irrigation water flow for environmental protection and landscaping, in particular to a multifunctional water gun with a high-performance dirt-proof replaceable nozzle, a water gun for gardening, gardening and cleaning, and particularly relates to a multifunctional water gun with a replaceable nozzle of a water gun with a water-gas adjusting atomization filter and a multifunctional water gun with a hook trigger, which are improved on the basis of a multi-stage water gun with a rapid adjustable flow, and belong to the technical field of spraying devices.

Background

There are also several patents relating to methods of controlling irrigation water flow, and also several patents relating to garden sprinkler timing switch with control of both sides of the long axis, such as patent US7252113B2, and patent ZL200820120164.8. Water guns for gardens, gardening, and cleaning are widely used to spray water in a manner selected by the preference of people. Currently, most of the commercial water sprayers are provided with handles and spring top plugs, and the working principle is mainly as follows: pressing down the handle to discharge water from the water gun; the handle is loosened, and the top plug is reset and sealed under the action of the spring. The water gun with the structure brings certain inconvenience to use, namely when the water gun is required to spray water for a continuous time, a user needs to press the handle all the time and can continuously discharge water, namely the user needs to press the handle all the time and can continuously discharge water, and the user can feel tired, especially for ladies, after a little longer time. Therefore, the water spraying gun is provided with the locking button with the rotating shaft, but the operation is troublesome, namely when the right hand is used for holding the water spraying gun handle, the locking button is required to be opened by a plurality of fingers and nails of the left hand, and then the locking button is turned for a larger angle, so that the locking button can be ensured to be fastened to the inside of the upper edge of the handle; the locking button is close to the gun body, and is often not grasped by wet fingers and is slipped off, so that the operation is very troublesome. The problem of frost cracking of the gun body is also more troublesome; in the past, water is sealed at the position of the gun body close to the pull rod plug, water is reserved in the gun body, and when the gun body is not used, freezing is generated when the gun body is cooled in the sky, so that the gun body is broken; although the gun body is strengthened and the sheath is covered with plastic, the gun body is not effective; how to prevent the gun body from icing and cracking is easy and difficult, and is a long-felt and unsolved problem in the field. In addition, the user also desires a slightly more spray pattern without rotational adjustment. Stepless adjustment of the monitor can avoid wasting water once it is pressed. In practice, the water gun can be operated by only one hand, either the left hand or the right hand, and the adjustment of pulling the water gun open by one finger or nail is a long-term expectation, so that the operation is convenient, and the water gun is good news for the disabled. For preventing occasional blocking, for adjusting atomization filtration and multi-color multi-spray head conversion, and for preventing freezing and reducing noise, an improved multifunctional water gun with a hook trigger is generated.
