Description

Technical Field

[0001] This invention relates to a method for controlling irrigation water flow for environmental protection and landscaping, a high-performance, anti-fouling, replaceable nozzle multi-functional water gun, a water gun for gardening, horticulture, and cleaning, and especially an improved version of a fast-adjustable flow front-trigger multi-stage water gun with a water-air regulating atomizing filter and replaceable nozzle logarithmic piston multi-functional water gun, belonging to the technical field of spraying devices. Background Technology

[0002] There are several patents related to methods for controlling irrigation water flow, as well as patents for timed switches for garden sprinklers with control on both sides of a long shaft, such as patent US7252113B2 and patent ZL200820120164.8. This results in higher requirements for manufacturing tolerances and precision, and also increases the possibility of occasional Euler instability of the pressure rod during long-term use; it also causes corrosion and adhesion over time, hindering operation. These products can be further improved; by incorporating certain components, making improvements and special integrations, and supplementing with inventions, the product can be taken to the next level; however, overcoming these shortcomings is by no means easy. Water guns used in gardens and horticulture, as well as water guns used for cleaning, are widely used to spray water in ways chosen by people's preferences. Currently, most water guns on the market have a handle and spring-loaded top plug structure. Their working principle is mainly: pressing the handle releases water; releasing the handle resets the top plug under the force of the spring and seals it. This type of water gun design presents certain inconveniences. When continuous water spray is required, the user must hold down the handle continuously for the water to flow. This constant pressure can cause fatigue, especially for women. To address this, a locking button with a rotating shaft is included. However, this is cumbersome. Holding the handle with the right hand requires using several fingers and fingernails of the left hand to pry open the locking button, rotate it to a considerable angle, and ensure it is securely fastened to the inside of the handle's upper edge. Furthermore, the button is close to the gun body, making it prone to slipping off with wet fingers, further complicating operation. An even more troublesome issue is the problem of the gun body freezing and cracking. Previously, the water seal on water guns was located near the lever stopper, leaving water inside the gun. When not in use, cold weather would cause ice to form, leading to cracks. Although reinforcing the gun body and adding a plastic protective sleeve have been tried, they haven't been effective. How to prevent the gun body from freezing and cracking has been a long-standing and unsolved problem in this field. In addition, users also hope for more spray patterns without the need for rotary adjustment. A stepless adjustable water gun avoids wasting water by pressing a button all the way down. In fact, water guns can be operated with just one hand, whether left or right; using a finger or nail to adjust the spray pattern has been a long-held desire. To prevent occasional jamming, to adjust the atomization filter and multiple spray patterns, to prevent freezing, to reduce noise, and to provide a burst of water for washing away dirt, a multi-functional water gun with a replaceable nozzle and logarithmic piston design has emerged. Summary of the Invention

[0003] To overcome the shortcomings of existing water guns; to prevent occasional jamming; to adjust atomization filtration and change between multiple colors and nozzles; and to prevent freezing and rinsing, an improved logarithmic piston multi-functional water gun with water and air regulation atomization filtration, modified from an adjustable water gun, was developed.

[0004] The key innovation is to replace the commonly used small switch trigger with an extra-large trigger that can be gripped with the full handle, and to use a double torsion spring elbow and a rear-mounted logarithmic piston to flush and control the rotating water inlet, thus forming a multi-functional water gun with a logarithmic piston for changing nozzles.

[0005] The technical solution adopted is:

[0006] Further innovation is made to create a multi-functional water gun with a replaceable nozzle and logarithmic piston. The highlight is that the commonly used small switch trigger is replaced with an extra-large trigger (21) that can be gripped by the whole hand. The logarithmic piston (25) with double torsion springs is used to control the flow regulating valve (26) with a logarithmic spiral groove (26a) in a rinsing manner. This forms a multi-functional water gun with a replaceable nozzle and logarithmic piston. The head of the gun body (3) is provided with a push slope (3ts) with an equiangular spiral that has the characteristic of equal pressure angle everywhere. The push slope contacts the button (3a) for control. Push key claws (3t) are provided on both sides of the push slope (3ts) to slide along the push groove of the gun body. The atomizing filter (31) at the head of the gun body (3) has eight rotating holes (31ac) evenly distributed along the center of the disc on the disc (7). The head of the gun body (3) is provided with an elastic ball (3ac) for the turntable; the upper nozzle of the replaceable nozzle is provided with an L-shaped locking groove (31sg) and a locking hook (31jg), and the lower nozzle of the replaceable nozzle is provided with a locking protrusion (3fg) and a locking recess (3fjg) for replacement; the edge curve of the hook (31jg) is approximately similar to an equiangular spiral with equal pressure angle everywhere, i.e., a logarithmic spiral, so as to cooperate with the screw locking; a horn-shaped channel is provided between the atomizer inlet (35) of the atomizing filter (31) at the head of the gun body (3) and the atomizer water-air mixing annular cavity (30), the curve of which is approximately similar to the function curve of the logarithmic spiral in higher mathematics; a foaming filter wedge array (38) is provided between the outer ring (32) of the filter and the atomizer water-air mixing annular cavity (30) to reduce noise.

[0007] The multi-functional water gun with a replaceable nozzle and a logarithmic piston has a button hook (3c) at the head of the gun body (3), which consists of a button (3a) and a locking hook (3f). The pivot in the middle of the button hook (3c) serves as the lever fulcrum. The button (3a) is located at the upper part of the lever of the button hook (3c), and the locking hook (3f) is located at the lower part of the lever of the button hook (3c) to lock the locking ring protrusion (31j) and locking groove (31s) at the root of the replaceable nozzle.

[0008] Further innovation involves replacing the nozzle with a logarithmic piston multi-functional water gun. Its highlights include a head containing an atomizing filter (31), a mesh cover (37), an aerator inlet (35), an aerator water-air mixing annular inner cavity (30), an aerator inner mesh cover (34), a filter outer ring (32), and an aerator filter wedge array (38). The nozzle head of the water gun with the water-air regulating atomizing filter is equipped with the atomizing filter (31), and the mesh cover (37) is located in front of the atomizing filter (31). The filter (31) has an aerator inlet (35) on its outer ring (32), and an aerator water-air mixing annular cavity (30) inside the atomizing filter (31). An aerator inner mesh cover (34) is provided on the aerator water-air mixing annular cavity (30). An aerator filter wedge array (38) is provided between the filter outer ring (32) and the aerator water-air mixing annular cavity (30). The aerator inlet (35) is connected to the aerator water-air mixing annular cavity (30). A funnel-shaped channel is provided between the annular inner cavity (30), the curve of which is approximately similar to the function curve of the logarithmic spiral in advanced mathematics; in order to facilitate the combined effect of filter and aerator, forming an air-injection type air intake inner and outer cavity; when the high-speed water jet rushes, due to the fluid dynamics principle that the greater the flow velocity, the smaller the side pressure, it drives the external air to enter the air-injection type air intake inner and outer cavity through the external air injection port provided in the air-injection type air intake annular outer cavity, and the local acceleration and unstable motion of fluid particles cause an unstable field and migration acceleration. The changes in degree and position cause an uneven flow field, forming a pulsating turbulent flow. The pulsating turbulent gas that makes up the air-injection type air intake outer cavity then enters the air-injection type air intake inner cavity from the inner air injection port provided on the side circumference of the air-injection type water-air mixing annular inner cavity of the bubbler. After passing through the foam filter core of the bubbler, the water-air mixture is foamed and mixed. The gradient, divergence and vortex of the foamed water-air mixture are further changed and dispersed. Under the adjustment of the extension or retraction of the spray bar operated by one hand, it sprays out water droplets in a spray shape or gently floats and spreads out.

[0009] An equiangular spiral with a constant pressure angle is also called a logarithmic spiral. This is taken from a section of the tooth profile of the toothed groove (21a) on the handle of the aforementioned shifter (21).

[0010] Establish the differential equation dρ / dθ=kρ:

[0011] Let the polar equation be ρ = ρ(θ). Since we want the pressure angle λ to be constant everywhere, tanλ = a constant. Let tanλ = k.

[0012] From the pressure angle formula tgλ=ρ' / ρ,

[0013] Then ρ' / ρ=k,

[0014] Differentiating this, we get the differential equation dρ / dθ=kρ;

[0015] Solve for dρ / dθ=kρ by separating variables and integrating both sides;

[0016] ∫dρ / ρ=∫kdθ, since ρ>0, it is easy to obtain:

[0017] lnρ=kθ+C,

[0018] Using PRO / ENGINEER WILDFIRE drawing software, create a new work directory and a new part.

[0019] Create parameter (PARAMETER)1: a real number in C, with a default value;

[0020] Create parameter (PARAMETER)2: N integers, default value assigned;

[0021] Establishing a relation (RELATION), i.e., an equation, is:

[0022] Logarithmic curve:

[0023] z = 0,

[0024] x = 10 * t,

[0025] y = log(10*t + 0.01),

[0026] Create a logarithmic curve;

[0027] Next, by using commands such as rotation, merging, and solidification, and assembling and merging with the workpiece, modeling can be achieved;

[0028] Then, using the aforementioned equations and the model created in PRO / ENGINEER WILDFIRE, input it into a CNC machining center. Use CIMATRO or MASTCAM to create a die-cast aluminum alloy steel mold, or use a milling machine, planer, and EDM machine as auxiliary tools. When using EDM, we have a unique approach: when inputting the aforementioned equations into a CNC machining center, it is necessary to first specially manufacture tungsten-copper-graphene electrodes, ideally using a machine tool with a three-dimensional rotary head. Then, use a die-casting machine with a hot press chamber to mass-produce the workpieces. The workpieces are mostly made of aluminum alloy ZL109 or AC8A; they can be machined and then polished.

[0029] The improved multi-functional water gun with a logarithmic piston and replaceable nozzle features a button hook (3c) at the head of the gun body (3), which consists of a button (3a) and a locking hook (3f). The pivot in the middle of the button hook (3c) serves as the lever fulcrum. The button (3a) is located at the upper part of the lever of the button hook (3c), and the locking hook (3f) is located at the lower part of the lever of the button hook (3c) to lock the locking ring protrusion (31j) and locking groove (31s) at the root of the replaceable nozzle. The advantage is that it overcomes the problem that the nozzle is loose when the tolerance is loose and difficult to pull out when the tolerance is tight. When inserting, the base of the replaceable nozzle can be easily inserted along the inclined surface of the card hook (3f). When pulling out, the button (3a) needs to be pressed down and the card hook (3f) provided at the lower part of the lever is released to easily replace the nozzle. The atomizing filter (31) of the multi-functional water gun with a logarithmic piston is provided with a mist screen (31t), holes (31x), fine nozzles (31a), coarse nozzles (31c), and triangular holes. Each hole is triangular and they are distributed in multiple concentric circles, interspersed with multiple conical holes, which is conducive to multiple colors. When spraying water, the multiple triangular holes and interspersed multiple conical holes and multiple nozzles on the color plate (7) and the atomizing filter (31) are mixed and squeezed, which is conducive to multiple colors. The improvement this time is to change the turntable hole (31ac) to a pentagon shape, which has a good effect because of the multiple sharp corners and multiple dispersion.

[0030] A multi-functional water gun with a replaceable nozzle and logarithmic piston includes an extra-large trigger (21), a rotating vane (22), a double torsion spring (23), a double spring disc (24), a logarithmic piston (25) with a logarithmic spiral convexity (25a), a flow regulating valve body (26) with a logarithmic spiral groove (26a) and an overflow port (26c). The double spring disc (24) is provided with a double spring shaft (24a) to facilitate the installation of the double torsion spring (23) and to facilitate the movable connection of the shaft to the upper two sides of the extra-large trigger (21). The upper part of the extra-large trigger (21) and the... The swivel plate (22) is movably connected to the connecting shaft (25d) of the logarithmic piston (25). If the lower part of the extra-large trigger (21) connected to the gun body (3) by a movable pin is fully gripped, the upper part of the extra-large trigger (21), the swivel plate (22), the double torsion spring (23), and the double spring disc (24) will reciprocate to push the logarithmic piston (25) with the logarithmic spiral cam (25a). The feature is that a logarithmic spiral cam is provided inside the flow regulating valve body (26) with the overflow port (26c). The rotating inlet channel of the groove (26a) forms a flow regulating valve body (26) with a logarithmic spiral groove (26a) and an overflow port (26c), in order to improve the flow regulating valve by utilizing the characteristic that the logarithmic spiral pressure angle is equal everywhere; it is further characterized in that the logarithmic piston (25) is provided with a logarithmic spiral protrusion (25a), forming a logarithmic piston (25) with a logarithmic spiral protrusion (25a), in order to further enhance the spiral ascent of the mixed water-air fluid and the piston propulsion and rotation stirring by utilizing the characteristic that the logarithmic spiral pressure angle is equal everywhere. The mixing effect of dynamic turbulence, and the end of the connecting thin shaft (25d) of the logarithmic piston (25) is provided with a column end inclined surface (25c) and a plunger ellipsoidal surface (25b) so as to reciprocate and micro-rotate in coordination with the upper part of the extra-large trigger (21) and the torsional swing of the rotating plate (22). The logarithmic piston (25) with double torsion springs is used to flush the flow regulating valve (26) with a logarithmic spiral groove (26a) rotating water inlet channel to form a rotating plunger type logarithmic piston multi-functional water gun with a change nozzle of a logarithmic piston flow regulating valve squeezing spray device;The aforementioned multi-functional water gun with a replaceable nozzle and logarithmic piston is characterized in that it is also equipped with an electronic descaling circuit, which changes the physical properties of minerals in the water by performing high-frequency electric field treatment, thereby achieving the purpose of descaling and preventing scale. It contains a 200KHZ rectangular wave oscillator, composed of a time base integrated circuit IC1, using a time base integrated circuit NE555, and related peripheral components. It contains a drive amplifier circuit, composed of a high-power electronic switch integrated circuit IC2, using a TWH8751 high-power electronic switch integrated circuit, an output transformer T1, and a capacitive load CL, etc. The capacitive load CL is connected to the part to be descaled by the copper mesh and insulating tube at the nozzle. The copper mesh of the capacitive load CL is connected to the output transformer T1, and the other end is connected to the outside of the insulating tube and the grounding terminal of the secondary side of the output transformer T1 and the metal at the base of the handle of the gun body (3). After the power switch S is turned on, the high-side voltage of the combined battery CELL (tens of volts, depending on the part to be descaled) is applied to the primary winding of the output transformer T1. The low-side voltage of the combined battery CELL (twelve volts) supplies the timer IC1 and the high-power electronic switch IC2. After the 200kHz rectangular wave oscillator is powered on, a 150-220kHz rectangular wave signal is output from pin 3 of the timer IC1. This rectangular wave signal is amplified by the high-power electronic switch IC2 and then drives the capacitive load CL through the output transformer T1 to generate a high-frequency electric field to treat the part to be descaled. Adjusting the resistance values ​​of the first potentiometer RP1 and the second potentiometer RP2 can change the operating frequency of the rectangular wave oscillator. Changing the rotary hole (31ac) to a pentagonal star shape has a good effect because more sharp corners result in more divergence.

[0031] Benefits:

[0032] The logarithmic piston flow regulating valve spray device utilizes the characteristic that the pressure angle of the logarithmic spiral is equal everywhere to further enhance the mixing effect of the spiral rise of the mixed water and air fluid and the piston propulsion and rotation stirring turbulence. It can also generate a high-frequency electric field for descaling treatment. Furthermore, the rotary hole (31ac) is changed to a pentagonal star shape to increase the color effect, and the multi-functionality of the logarithmic piston multi-functional water gun with replaceable nozzles is gradually improved.

[0102] Because the system is developed and improved gradually through continuous changes, some parts may be replaced without prior notice, such as the substitution of standard parts like seals and screws. Detailed Implementation

[0103] The operator must connect the water supply hose and select the correct function before use.

[0104] To overcome the shortcomings of existing water guns, improvements were first made to a multi-stage water gun with a front trigger and adjustable flow rate. This improved version incorporated an electromagnetic pump valve within the gun body to facilitate pressure and flow rate adjustment via the front trigger, and also included an anti-freeze handle for further freeze protection. The water gun was developed and improved through gradual refinement and continuous modification.

[0105] Users also wanted more water spray patterns without having to rotate the control panel. A simple solution was discovered: usually, the color wheel has many small round holes. When a small round hole is missing, forming a triangle, the color change is only noticed. It's like a blessing in disguise. Because the color wheel (7) has multiple triangular holes, each of which is triangular and distributed in multiple concentric circles, interspersed with multiple conical holes, it is advantageous for multiple colors. A water gun with a continuously improved and perfected color wheel (7) has multiple conical holes, each of which has a conical cross-section, allowing for color changes.

[0106] The multi-functional water gun with a logarithmic piston nozzle has a push-in inclined surface (3ts) with an equiangular spiral having the characteristic of equal pressure angle everywhere, which contacts the button (3a) for control; the atomizing filter (31) has a color disc (7) with eight rotating holes (31ac) and an elastic ball (3ac) for rotating the disc; the upper nozzle has an L-shaped locking groove (31sg) and a locking hook (31jg), and the lower nozzle has a locking protrusion (3fg) and a locking recess (3fjg) for replacement; the edge curve of the locking hook (31jg) is approximately similar to a logarithmic spiral for locking; a funnel-shaped channel with a curve approximately similar to the function curve of a logarithmic spiral in higher mathematics is provided between the aerator inlet (35) and the aerator water-air mixing annular cavity (30); a foaming filter wedge array (38) is provided between the filter outer ring (32) and the aerator water-air mixing annular cavity (30) for noise reduction.

[0107] The continuously improved replaceable nozzle logarithmic piston multi-functional water gun has the following highlights: a button hook (3c) is provided at the head of the gun body (3), which consists of a button (3a) and a locking hook (3f). The pivot in the middle of the button hook (3c) serves as the lever fulcrum. The button (3a) is provided at the upper part of the lever of the button hook (3c), and the locking hook (3f) is provided at the lower part of the lever of the button hook (3c) to lock the locking ring protrusion (31j) and locking groove (31s) at the root of the replaceable nozzle. The advantage is that it overcomes the problem that the replaceable nozzle is loose when the tolerance is loose and difficult to pull out when the tolerance is tight. When inserting, the base of the replaceable nozzle can be easily inserted along the inclined surface of the card holder hook (3f). When pulling out, the button (3a) needs to be pressed down and the card holder hook (3f) provided at the lower part of the lever is released to easily replace the nozzle. The atomizing filter (31) of the multi-functional water gun with a logarithmic piston is provided with a mist screen (31t), orifices (31x), fine nozzles (31a), coarse nozzles (31c), ten-hole nozzles (31f), double-ring nozzles (31g), slotted nozzles (31h), and grooved nozzles (31k). The orifices (31x) are provided with multiple conical holes, each of which has a conical cross-section to facilitate changing patterns.

[0108] The multi-functional water gun with a logarithmic piston and replaceable nozzles is equipped with a button hook (3c), which consists of a button (3a) and a retainer hook (3f), serving as a lever fulcrum. The button (3a) on the lever of the button hook (3c) connects to the retainer hook (3f) at the lower part of the lever to lock the retaining ring protrusion (31j) and retaining groove (31s) at the root of the replaceable nozzle. It is equipped with a mist screen (31t), orifices (31x), fine nozzles (31a), coarse nozzles (31c), ten-hole nozzles (31f), double-ring nozzles (31g), slotted nozzles (31h), and grooved nozzles (31k). The orifices have multiple conical holes, each with a conical cross-section. The orifices also have multiple triangular holes, each triangular in shape, interspersed with multiple conical holes. When spraying water, the rapid water jet is micro-atomized and sprayed from multiple triangular holes, interspersed with multiple conical holes and multiple nozzles, which facilitates multiple colors.

[0109] Benefits:

[0110] Further innovations include a multi-functional water gun with a logarithmic piston nozzle. Its highlights include a push-in inclined surface (3ts) with an equiangular spiral exhibiting equal pressure angles at every point on the head of the gun body (3). This push-in inclined surface contacts the button (3a) for control. Push-key claws (3t) are located on both sides of the push-in inclined surface (3ts) to slide along the push groove of the gun body. The atomizing filter (31) at the head of the gun body (3) has eight rotating holes (31ac) evenly distributed around its center on its disc (7). An elastic ball bearing (3ac) is located at the head of the gun body (3) to facilitate the rotation of the disc. The replaceable nozzle's upper nozzle has an L-shaped locking groove (31sg). The lower nozzle of the replaceable nozzle is provided with a locking protrusion (3fg) and a locking recess (3fjg) for easy replacement; the edge curve of the locking hook (31jg) is approximately similar to an equiangular spiral with equal pressure angle everywhere, i.e., a logarithmic spiral, so as to cooperate with the screw locking; a horn-shaped channel is provided between the atomizer inlet (35) of the atomizing filter (31) at the head of the gun body (3) and the atomizer water-air mixing annular cavity (30), the curve of which is approximately similar to the function curve of the logarithmic spiral in higher mathematics; a foaming filter wedge array (38) is provided between the outer ring (32) of the filter and the atomizer water-air mixing annular cavity (30) to reduce noise.

[0111] A multi-functional water gun with a replaceable nozzle and logarithmic piston includes an extra-large trigger (21), a rotating vane (22), a double torsion spring (23), a double spring disc (24), a logarithmic piston (25) with a logarithmic spiral convexity (25a), a flow regulating valve body (26) with a logarithmic spiral groove (26a) and an overflow port (26c).

It contains a drive amplifier circuit, composed of a high-power electronic switch integrated circuit IC2, using a TWH8751 high-power electronic switch integrated circuit, an output transformer T1, and a capacitive load CL, etc. The capacitive load CL is connected to the part to be descaled by the copper mesh and insulating tube at the nozzle. The copper mesh of the capacitive load CL is connected to the output transformer T1, and the other end is connected to the outside of the insulating tube and the grounding terminal of the secondary side of the output transformer T1 and the metal at the base of the handle of the gun body (3). After the power switch S is turned on, the high-side voltage of the combined battery CELL (tens of volts, depending on the part to be descaled) is applied to the primary winding of the output transformer T1. The low-side voltage of the combined battery CELL (twelve volts) supplies the timer IC1 and the high-power electronic switch IC2. After the 200kHz rectangular wave oscillator is powered on, a 150-220kHz rectangular wave signal is output from pin 3 of the timer IC1. This rectangular wave signal is amplified by the high-power electronic switch IC2 and then drives the capacitive load CL through the output transformer T1 to generate a high-frequency electric field to treat the part to be descaled. Adjusting the resistance values ​​of the first potentiometer RP1 and the second potentiometer RP2 can change the operating frequency of the rectangular wave oscillator. Changing the rotary hole (31ac) to a pentagonal star shape has a good effect because more sharp corners result in more divergence.
