Description

Technical Field

[0001] The present invention relates to a method for controlling irrigation water flow for environmental protection and landscaping, a high-performance anti-fouling multifunctional water gun with replaceable nozzles, a water spray gun for gardening, horticulture and cleaning, especially a multifunctional water gun with replaceable nozzles and a telescopic long water gun with a rotatable nozzle, which is improved on the basis of a front trigger multi-stage water gun with a fast adjustable flow rate and a water spray gun with a water vapor regulating atomizing filter, belonging to the technical field of spray devices. Background Art

[0002] The desire to pursue environmental protection and landscaping is endless; there are also multiple patents for the control method of irrigation water flow, and the patents for the timer switch of the garden sprinkler with long-axis control on both sides. In fact, there may be high requirements for the precision of manufacturing tolerance matching, which may cause the occasional Euler instability of the pressure rod during long-term use; it also causes rust and adhesion over time and hinders the action; this type of product needs to be further improved, not only in fine structure but also in opto-acoustic electromechanical remote control. Spray guns used for gardening and gardening, as well as spray guns for cleaning, are widely used to spray water in the way chosen by people's preferences. At present, most of the spray guns on the market have a handle and a spring top plug structure. Its working principle is mainly: press the handle to discharge water from the gun; release the handle, and the top plug is reset and sealed under the action of the spring. The water spray gun of such structure brings some inconvenience to the use, that is, when the water spray gun needs to spray water continuously, the user needs to keep pressing the handle, and the water spray gun can continuously discharge water, that is, the user needs to keep pressing the handle, and the water spray gun can continuously discharge water, which will make the user feel tired if the time is a little longer, especially for women. For this reason, a locking button with a rotating shaft is provided on the water spray gun, but it is troublesome to operate, that is, when holding the handle of the water spray gun with the right hand, the locking button must be unlocked with several fingers and nails of the left hand, and then the locking button must be turned to a larger angle, and the locking button must be ensured to be fastened to the inner side of the upper edge of the handle; the locking button is close to the gun body, and it is often difficult to grasp with wet fingers and slips off, which is very troublesome to operate. There is even more trouble, that is the problem of freezing and cracking of the gun body. In the past, the water seal of the water gun was near the rod plug of the gun body, and water was retained in the gun body. When it was not in use, it would freeze and cause the gun body to crack in cold weather. Although we have tried to strengthen the gun body and add plastic wrapping and sheathing, it did not work. How to prevent the gun body from freezing and cracking is easier said than done, and it is a long-standing and difficult problem in this field. In addition, users also hope that there will be a little more water spraying patterns without turning to adjust. The stepless adjustment water spray gun can avoid wasting water by pressing all the way. In fact, you can operate the water gun with just one hand, whether it is the left hand or the right hand. It is a long-standing expectation to use a finger or fingernail to adjust.In order to prevent occasional jamming, to adjust atomization filtration and multi-color and multi-sprinkler conversion, and to prevent freezing, a multifunctional water gun with replaceable nozzles has been improved. The nozzle head of the rotatable nozzle (41) of the water gun is provided with an atomization filter (31), a mesh cover (37), a bubbler inlet (35), a bubbler water-gas mixing annular inner cavity (30), a bubbler inner mesh cover (34), a filter outer ring (32), and a bubbler filter wedge array (38). The mesh cover (37) is provided in front of the atomization filter (31). The atomization filter The outer ring (32) of the filter (31) is provided with the bubbler inlet (35), the atomizing filter (31) is provided with the bubbler water-gas mixing annular inner cavity (30), the bubbler water-gas mixing annular inner cavity (30) is provided with the bubbler inner mesh cover (34), and the bubbler filter wedge array (38) is provided between the outer ring (32) of the filter and the bubbler water-gas mixing annular inner cavity (30); the bubbler inlet (35) is connected to the bubbler water-gas mixing annular inner cavity (30). A trumpet-shaped channel is provided between the annular inner chambers (30), and its curve is similar to the function curve of the logarithmic spiral in higher mathematics; so as to form the comprehensive effect of the filter and the bubbler, and form the inner and outer chambers of the air injection type air intake; when the high-speed water flow is running, due to the fluid mechanics principle that the greater the flow rate, the smaller the pressure beside it, the external air is driven to enter the inner and outer chambers of the air injection type air intake through the external air injection port provided in the annular outer chamber of the air injection type air intake, and the local acceleration and the unstable motion of the fluid particles cause an unstable field and migration acceleration The change of degree and position causes uneven flow field, forming pulsating turbulence. The pulsating turbulent gas constituting the air injection type air inlet outer cavity then enters the air injection type air inlet inner cavity from the inner air injection port provided on the side circumference of the bubbler air injection type water gas mixing annular inner cavity, and is bubbled and mixed with water gas through the bubbler foam filter element. The gradient, divergence and rotation of the fluid after the bubble water gas mixing are further changed and dispersed, and under the adjustment of the extension or contraction of the operable spray rod, water sprays out in the form of spray or gently flutters and spreads out. The market needs a telescopic long water gun with a rotatable nozzle for convenience and a large spray surface. Summary of the invention

[0003] In order to overcome the shortcomings of existing water guns, to prevent occasional jams, to adjust the atomization filtration and the conversion of multiple colors and multiple nozzles, and to prevent freezing, a multifunctional water gun with an improved replaceable nozzle with water vapor adjustable atomization filtration and a retractable long water gun with a rotatable nozzle modified from an adjustable water spray gun came into being.

[0057] The operator must connect the water supply hose and use the airbag inflator if remote control is required.

[0058] In order to overcome the shortcomings of existing water guns, improvements were first made on the front trigger multi-stage water gun with fast adjustable flow. An electromagnetic pump valve was installed in the gun body to facilitate the use of the front trigger to adjust the pressure and flow, and an antifreeze gun handle was also provided to further improve antifreeze. Later, an infinitely adjustable antifreeze garden water spray gun was also improved; this improvement was based on gradual formation and continuous modification.

[0059] Users also hope that the water spray pattern can be slightly more, and the simple method without rotating the control is a small discovery: usually there are many small round holes on the color plate, and the color is changed when a small round hole is missing like a triangle. Because the color plate is provided with multiple triangular holes, each hole is triangular, and they are distributed according to multiple concentric circles, and multiple conical holes are arranged in between, so it is conducive to multiple colors. When spraying water, the spray rod is provided with a guide surface and a pull rod plug, and the rushing water spray is slightly atomized from multiple triangular holes and multiple conical holes and multiple nozzles to mix and squeeze spray, which is conducive to multiple colors. The generatrix of the curved surface of the conical conical surface of the rod plug is an equiangular spiral with the characteristic of equal pressure angle everywhere, also known as a logarithmic spiral; therefore, the equiangular spiral surface of the rod plug provided on the rod of the rod plug ensures a smooth fit and no jamming with the push head provided on the upper part of the antifreeze remote water stop plug; its essence is that the cam matching surface of the mechanized cam mechanism is an equiangular spiral surface with equal pressure angle everywhere, also known as a logarithmic spiral surface, which is an innovation in water guns. It is reliable, affordable, and does not jam, so antifreeze can be implemented, and the performance and working quality of such products are improved.
