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, and particularly a modified multi-stage thumb-adjustable water gun based on a front trigger multi-stage water gun with a fast adjustable flow rate, a water spray gun with a water vapor regulating atomizing filter, and a multifunctional water gun with a replaceable nozzle logarithmic piston, belonging to the technical field of spray devices. Background Art

[0002] The desire to pursue environmental protection and landscaping is endless; there are also many patents on the control method of irrigation water flow, and the patents of the timer switch of the garden sprinkler with long-axis control on both sides. Some of them have high requirements for the precision of manufacturing tolerances, or may cause the occasional Euler instability of the pressure rod in long-term use, or cause rust and adhesion over time to hinder the action; this type of product can be further improved, thinking of the inspiration of the 1,000 patents in eight countries and some devices involved in the manufacture of foreign factories such as Switzerland and Israel, and improving and blending them, and then supplementing them with innovation to make the product a higher level; but it is not easy to correct the shortcomings. Water spray guns used in gardens and gardening, as well as water spray guns used for cleaning, are widely used to spray water in the way chosen by people's preferences. At present, most of the water 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 water 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 the gun body freezing and cracking; 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 it all the way. In fact, only one hand is needed, whether it is the left hand or the right hand, to operate the water gun. Using one finger or nail to open the adjustment is a long-standing expectation, which is not only convenient to operate, but also a blessing for the disabled. In order to prevent occasional jams, to adjust the atomization filter and the conversion of multiple colors and multiple nozzles, and to prevent freezing, to reduce noise, and to have an instant burst of water to wash dirt, a modified multi-stage thumb-adjustable water gun came into being. Summary of the invention

[0003] In order to overcome the shortcomings of existing water guns; to prevent occasional jamming, to adjust the atomization filtration and the conversion of multiple colors and multiple nozzles, and also for anti-freezing and flushing, a modified multi-section head thumb-adjustable water gun with an improved replaceable nozzle logarithmic piston multifunctional water gun with water vapor adjustable atomization filtration, which is modified from an adjustable water spray gun, was born to further diversify the product series and allow international customers to have more choices.

[0004] The first innovation was to replace the commonly used small switch trigger with an extra-large trigger that can be gripped with a full hand, and to use a double torsion spring to control the rear logarithmic piston to flush the rotating water inlet to form a multi-functional water gun. Later, for the convenience and needs of the disabled, it was improved to a modified multi-stage thumb-adjustable water gun with music and lights that can be operated by a single thumb.

[0005] The technical solutions adopted are:

[0006] Further innovation was made, and various series of water guns were trial-produced step by step. The highlight of the invention is that the commonly used small switch trigger is replaced by an extra-large trigger (21) that can be fully gripped, and a logarithmic piston (25) with a double torsion spring is used to control the flow regulating valve (26) of the rotating water inlet with a logarithmic spiral groove (26a) in a flushing manner so as to form a logarithmic piston multifunctional water gun with a replaceable nozzle, wherein a push slope (3ts) with an equiangular spiral with the characteristic of equal pressure angle is provided at the head of the gun body (3), and the push slope contacts the button (3a) for control, and push key claws (3t) are provided on both sides of the push slope (3ts) so as to slide along the push groove of the gun body; and a color disk (7) of the atomizing filter (31) at the head of the gun body (3) is provided with eight rotating disk holes (31ac) evenly distributed along the center of the disk. , an elastic bead (3ac) is provided at the head of the gun body (3) for turning the disk; an L-shaped locking groove (31sg) and a locking hook (31jg) are provided on the upper nozzle of the replaceable nozzle, and a locking convex (3fg) and a locking concave (3fjg) are provided on the lower nozzle of the replaceable nozzle for replacement; the edge curve of the hook edge of the locking hook (31jg) is approximately similar to an equiangular spiral with a characteristic of equal pressure angle everywhere, that is, a logarithmic spiral, so as to cooperate with the rotation; a trumpet-shaped channel is provided between the bubbler inlet (35) of the atomizing filter (31) at the head of the gun body (3) and the bubbler water-gas mixing annular cavity (30), and its curve is approximately similar to the function curve of the logarithmic spiral in higher mathematics; a bubbler filter wedge array (38) is provided between the filter outer ring (32) and the bubbler water-gas mixing annular cavity (30) for noise reduction.

[0007] Various series of water guns are trial-produced step by step. A button hook (3c) is provided at the head of a gun body (3), which is composed of a button (3a) and a base hook (3f). The rotating shaft in the middle of the button hook (3c) is used as a lever fulcrum. The button (3a) is provided at the upper part of the lever of the button hook (3c), and the base hook (3f) is provided at the lower part of the lever of the button hook (3c) so as to clamp the clamping ring protrusion (31j) and the clamping groove (31s) at the root of the replaceable nozzle.

[0008] Further innovation, step by step trial production of a variety of series of water guns, the highlight of which is that the head contains an atomizing filter (31), a mesh cover (37), a bubbler inlet (35), a bubbler water vapor mixing annular cavity (30), a bubbler inner mesh cover (34), a filter outer ring (32), and a bubbler filter wedge array (38); the nozzle head of the water spray gun with a water vapor regulating atomizing filter is provided with the atomizing filter (31), the mesh cover (37) is provided in front of the atomizing filter (31), and the atomizing filter (31) is provided with a mesh cover (37). The filter (31) has a bubbler inlet (35) on the filter outer ring (32), a bubbler water-gas mixing annular inner cavity (30) inside the atomizing filter (31), a bubbler inner mesh cover (34) on the bubbler water-gas mixing annular inner cavity (30), and a bubbler filter wedge array (38) between the filter outer ring (32) and the bubbler water-gas mixing annular inner cavity (30); the bubbler inlet (35) and the bubbler water-gas mixing annular inner cavity (30) are connected to each other. A trumpet-shaped channel is provided between the annular inner chamber (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 changes in degree and position cause an uneven flow field, forming a pulsating turbulence. The gas of the pulsating turbulence 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 vapor mixing annular inner cavity, and is bubbled and mixed with water vapor through the bubbler foam filter element. The gradient, divergence and rotation of the bubbled water vapor mixture are further changed and diffused, and under the adjustment of the extension or contraction of the spray rod operated by one hand, it is sprayed out in the form of spray or softly flutters and spreads out.

[0009] The equiangular spiral with the characteristic of equal pressure angle is also called logarithmic spiral. The differential equation dρ / dθ=kρ is established: Let the polar coordinate equation ρ=ρ(θ). Since we want the pressure angle λ to be equal everywhere, tgλ=constant, let tgλ=k,

[0010] According to the pressure angle formula tgλ=ρ' / ρ,

[0011] So ρ' / ρ=k,

[0012] Differentiating it, we have the differential equation dρ / dθ=kρ;

[0013] Solve dρ / dθ=kρ, separate the variables and integrate both sides;

[0014] ∫dρ / ρ=∫kdθ, because ρ>0, it is easy to get:

[0015] lnρ=kθ+C,

[0016] Use PRO / ENGINEER WILDFIRE drawing software, set up new working directories, create new parts,

[0017] Create parameter (PARAMETER) 1: C real number (real number), default value;

[0018] Create parameter (PARAMETER) 2: N integer (integer), default value;

[0019] Establish a relationship (RELATION), that is, the equation is:

[0020] Logarithmic curve:

[0021] z=0,

[0022] x = 10*t,

[0023] y=log(10*t+0.01),

[0024] Make a logarithmic curve;

[0025] Then, use the rotation, merging, solidification and other instructions, and assemble and merge with the workpiece to build the model;

[0026] Then use the equation and PRO / ENGINEER WILDFIRE to model and input it into the CNC machining center, use CIMATR0 or MASTCAM to make steel molds for die-casting aluminum alloy, or use milling machines, planers and EDM to assist work; when we use EDM in our original way, use the equation to input it into the CNC machining center, then we must first specially make tungsten copper graphene electrodes, and it is ideal to use a machine tool with a three-dimensional rotating head; then use a die-casting machine with a hot press chamber to mass produce it; it can be machined and then polished.

[0027] The invention gradually improves and trial-produces various series of water guns step by step. The highlight is that a button hook (3c) is provided at the head of the gun body (3), which is composed of a button (3a) and a base hook (3f). The rotating shaft in the middle of the button hook (3c) is used as a lever fulcrum. The button (3a) is provided at the upper part of the lever of the button hook (3c), and the base hook (3f) is provided at the lower part of the lever of the button hook (3c) so as to clamp the clamping ring protrusion (31j) and the clamping groove (31s) at the root of the replaceable nozzle. The advantage is that the problem that the replaceable nozzle is loose when the tolerance is loose and difficult to be pulled out when the tolerance is tight is overcome. When inserting, the root of the replaceable nozzle can be easily inserted along the inclined surface of the socket hook (3f), and when pulling out, the button (3a) needs to be pressed to release the socket hook (3f) provided at the lower part of the lever to easily replace the nozzle; the atomizing filter (31) of the logarithmic piston multifunctional water gun for replacing the nozzle is provided with a mist net cover (31t), an eyelet (31x), a fine nozzle (31a), a coarse nozzle (31c), a ten-hole nozzle (31f), a double-ring nozzle (31g), a hole-groove nozzle (31h), and a grooved nozzle (31k); the eyelet (31x) is provided with a plurality of conical holes, and the cross section of each hole is conical, so as to facilitate the clearance with the spray rod (6). The pattern can be changed by coordination; a simple method to make the water spray pattern a little more is a small discovery: usually there are many small round holes on the pattern plate, and the pattern is changed when a small round hole is missing like a triangle. It can be said that after many efforts, there is an occasional harvest; because some of the holes are also provided with a plurality of 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 patterns; when spraying water, the multiple triangular holes on the pattern plate (7) and the atomizing filter (31) and the multiple conical holes arranged in between and the multiple nozzles are mixed and squeezed and sprayed, so it is conducive to multiple patterns; this improvement is to change the turntable hole (31ac) into a five-pointed star shape, which has a good effect because of the multiple sharp corners and divergence.

The swing plate (22) is movably connected to the connecting thin shaft (25d) of the logarithmic piston (25). If the lower part of the extra-large trigger (21) connected to the gun body (3) through the movable pin is pressed with a full hand, the upper part of the extra-large trigger (21) and the swing plate (22) as well as the double torsion spring (23) and the double spring disk (24) will reciprocate and push the logarithmic piston (25) with the logarithmic spiral protrusion (25a).

The invention relates to a method for controlling the mixing effect of dynamic turbulence, and a column end inclined surface (25c) and a plunger ellipsoidal surface (25b) are provided at the end of the connecting thin shaft (25d) of the logarithmic piston (25) so as to cooperate with the upper part of the extra-large trigger (21) and the torsion swing of the swing plate (22) to reciprocate and slightly rotate. The rearward logarithmic piston (25) is controlled by a double torsion spring to flush the flow regulating valve (26) of the rotating water inlet with a logarithmic spiral groove (26a), so as to form a rotating plunger type logarithmic piston flow regulating valve squeezing device with a replaceable nozzle logarithmic piston multifunctional water gun;The step-by-step trial production of various series of water guns is characterized in that it is also provided with an electronic descaling circuit for the water gun, which achieves the purpose of descaling and preventing scale by subjecting water to high-frequency electric field treatment to change the physical properties of minerals in the water.

[0120] The operator must connect the water supply hose and select the function before use.
