Automatically-unlocking type garden water gun

Abstract

The invention discloses an automatically-unlocking type garden water gun. Roll ball bearings (18c) of a rotating anti-winding inner core (32) are roll balls which can be rolled and arranged on a rolling cylinder of the inner core, the roll balls are arranged according to a Yang Hui triangle from the top to the bottom and from sparseness to denseness, the lower end is provided with extension clamping tubes (18a2), so that the screwing problem of a screw thread of the inner core (32) and a screw thread of a water inlet pipe joint is solved; a cross section of table shoulders is a section of a logarithmic spiral; a screw thread fills a turnbuckle; and the inner ring of the rotating anti-winding inner core (32) is provided with spiral rotary plugs (5k) for facilitating installation of the water inlet pipe joint and an electromagnetic pump. The invention provides improvement of an electromagnetic pump used for the water gun, the electromagnetic pump can be called an electromagnetic pump ofwhich the interior is provided with a push-pull double-press valve core structure, a giraffe-type tension spring with no reduction of a flow rate, the spiral rotary plugs with a larger flow rate and aplug with a logarithmic line or a parabola for the larger-pressure larger-flow-rate water gun; and the electromagnetic pump can increase internal pressure, make relative working states among each part improved, and greatly increase pressure and a flow rate.

Description

technical field [0001] The invention relates to a water spray device for gardening, gardening and cleaning, commonly known as a water gun, especially a modified air-injected garden water gun, which is an improvement of the hand-automatic switching type water gun, and belongs to the technical field of spray devices ; It also belongs to the field of special offerings for the handicapped water gun for the handicapped. It is a switchable water type device of the water outlet device, and the water inlet end of the bubbler is added with a 360-degree rotating anti-winding garden water gun to meet the market demand for rotating and anti-winding, and solve how to make the spray water not spray out but soft The problem of loose ground dancing and the problem of water gun plus electromagnetic pump pressurization. Background technique [0002] For gardening, water spray guns for gardening, and water spray guns for cleaning are widely used to spray water in the selected mode of people's...

AI Technical Summary

Problems solved by technology

The disadvantage of conventional product design is that the user needs to hold the gun with one hand and rotate the head section cover of the water gun with the other hand to achieve the purpose of switching the water type during use.

The water spray gun with such a structure brings certain inconvenience to use, that is, when the water gun needs to spray water for a continuous time, the user needs to press the handle all the time, so that the water gun can continuously discharge water, that is to say, the user needs to press the handle all the time. Only when the handle is held, the water gun can continuously discharge water. A little longer time will make the user feel tired, especially for women.

For this reason, the water spray gun is provided with the pull lock (14b) of the triangular ring belt rotating shaft, but it needs to use two hands, that is to say when holding the water spray gun handle and the handle with the right hand, with the left hand several Fingers and fingernails are used to buckle the pull lock (14b), and then turn it to a larger angle such as 45 degrees, and make the pull lock to ensure that it can be fastened to the upper edge of the handle and when stopping, hold the handle and the handle of the spray gun tightly with the right hand so that the trigger lock (14b) can be disengaged, and use the fingers and nails of the left hand to remove it. Unlock the described pull lock (14b), and then turn it to a larger angle such as 45 degrees, and also make the described pull lock able to fasten to the buckle position on the upper edge of the handle; It can be seen that two-handed operation is very troublesome, especially when the hands are wet and slippery; this kind of operation method using two hands is too cumbersome, and the user is not user-friendly when using it; let alone a one-handed disabled person cannot used

Therefore, people are seeking to design a water gun that allows the user to operate with only one hand during the entire use process, lock it if you want to lock it, open it if you want to open it, change it if you want to change it, and spend it with one hand. It is easy to operate, which is easy to say, seemingly simple, but difficult to do. It is a long-standing unsolved problem in this field; before we produced and certified the automatic manual switching water gun of the present invention, there was no The first true one-handed operation of its kind
