Description

Technical Field

[0001] The present invention relates to a method for controlling irrigation water flow for environmental protection and landscaping, which is a high-performance anti-fouling swing sprinkler and a water-saving method, including an electromagnetic flowmeter and a circuit of a new energy-saving impeller suspension shaftless bracket for energy-saving agriculture and forestry irrigation, and a water-saving method, including a flow-adjustable dripper, a 360-degree nozzle, a joint with fine-tunable threaded ring size and pitch, and a combination with an energy-saving sprinkler timer and a water distributor, a garden hose, and a remotely controllable pressurized electric sprinkler. Background Art

[0002] The desire to pursue environmental protection and gardening is endless; there are also many patents on the control method of irrigation water flow and the patent of the garden sprinkler timer switch with long axis and two sides control, such as patent US7252113B2 and patent ZL200820120164.8, both of which use the garden sprinkler timer switch with long axis and two sides control. Although the mechanical timer has a wide range of uses due to its strong structure, strong weather resistance, reliable use, and excellent cost performance, the two ends of the double gear shaft (11) are respectively mounted in the two oblong holes of the mechanical timer frame, and only one end has an auxiliary spring, while the other end does not have an auxiliary spring, lacking the proper balancing torque, so when twisting and running, the double gear shaft (11) and the meshing main gear shaft (15) cannot be parallel, and there is a potential hidden danger of long-term operation wear resistance and stability. Furthermore, due to structural problems, the main control valve and the pilot valve are arranged on one side of the main channel, and the mechanical timer is arranged on the other side of the main channel, causing the mechanical timer to be far away from the main control valve and the pilot valve that it should directly control, and has to be remotely pushed out with a very long stainless steel rod, which not only creates higher requirements for the precision of manufacturing tolerance matching, but also causes the possibility of occasional Euler instability of the pressure rod during long-term use; it also causes the stainless steel rod to be exposed and pass through the main channel, which is prone to rust and adhesion over time and hinders the movement; in addition, the stainless steel rod passing through the main channel also has a problem of sealing and leakage over time. Furthermore, the scheme of arranging the main control valve and the pilot valve on one side of the main channel and arranging the mechanical timer on the other side of the main channel is based on the conventional idea that the remote main control valve, the pilot valve and the main channel are immovable relative to the main body of the mechanical timer. Therefore, the remote main control valve, the pilot valve and the main channel are connected to the main body of the mechanical timer by a larger housing, resulting in a larger appearance of the garden sprinkler timing switch; at the same time, in addition to the thin shaft of the main gear shaft (15) that plays a controlling role of the mechanical timer, a large rotating gradient circle and several parts have to be used for rotation and control, that is, the multiple parts make some aspects of the rotating gradient circle, such as the plastic square hole in the middle, subject to lateral deflection torque, causing the gradient circle disk surface to be skewed and affecting the effect.In summary, this type of watch product can be further improved. Considering the inspiration from the thousands of patents in eight countries and some devices manufactured by foreign factories such as Switzerland and Israel, they can be improved and specially blended, and then supplemented with innovation to make the products even better. However, even if the timer and sprinkler are easy to use, it will not work if the interface is not good. In practice, some are pipe interfaces, and some are faucets without threads. The method of adding more interfaces has been used, which is okay for faucets and some interfaces, but not for many interfaces. The reason is that many interfaces in a garden have been worn or rusted, and the threads of many interfaces have loose threads, and they cannot be connected or connected tightly, and they leak when connected. The threads of many interfaces are similar but different threads are mixed together. It is not easy to replace a large number of interfaces. Even if they are replaced, many threads on the original water pipes have loose threads, and the replaced interfaces will also be worn or rusted, and the new interfaces also have upper or lower tolerances and exceed tolerances, and cannot be connected or connected. There are many problems of tightness and slipping of the threads; there is also the problem of slow operation that a hand tool needs to be twisted half a turn and then changed hands to twist half a turn many times to complete a thread; whether it is used for sprinkler timer and irrigation water distributor or other, it is very desirable to have a portable electric sprayer and a garden hose that can spray automatically, so as to utilize the water hammer effect and improve the flow saving and adjustable dripper that can be placed in a dead corner and the water saving method using a micro-swing S-shaped spiral spray head and a capillary wetting head. An improved portable electric sprayer based on a garden hose that can spray automatically is born. The key point is that the auxiliary support plate (2) changes the passive assistance to the S-shaped spiral spray head (4) and the capillary wetting hose (4c) passing through by the electric incomplete gear reciprocating pause method to actively assist and utilize the water hammer effect to perform self-excited multi-harmonic oscillation to facilitate shaking spraying; continuous development and improvement on the original basis is cost-saving, and according to customer requirements, a pressurized electric sprayer that can be remotely controlled is developed. Summary of the invention

[0003] In practice, there is a need for a more water-saving improved portable electric sprayer that is compatible with a garden hose that can spray automatically, so as to improve the flow saving and the adjustable dripper that can be placed in any dead corner with a garden hose, as well as a water-saving method using a micro-swing S-shaped spiral spray head and a capillary wetting head. A remotely controllable pressurized electric sprayer that utilizes a water hammer effect and self-excited multi-harmonic oscillation has come into being. The electric incomplete gear reciprocating pause method is added to improve the auxiliary support plate (2) from passive assistance to active assistance for the S-shaped spiral spray head (4) and the capillary wetting hose (4c) passing through, so as to facilitate shaking spraying. If the device can spray water intermittently, water can be saved. If a complex structure is used, the cost is high and it is easy to damage. It is hoped that the device can spray water high and far at once and then pause or reduce the spraying time to oscillate and spray water at short intervals. This will have a good effect and save water. It is thought that the portable electric sprayer that can be used to improve the self-spraying garden hose can be used to improve the portable electric sprayer. When the flow of the fluid is blocked, the fluid will produce irregular water hammer and surge in the transmission system, thereby generating strong shock waves. Therefore, an improved portable electric sprayer with a water hammer shuttle controlled spray head that can be used to improve the self-spraying garden hose came into being. The key point of innovation is to add an electric incomplete gear reciprocating pause method to change the auxiliary support plate (2) from passive to active to assist the S-shaped spiral spray head (4) and the capillary wetting hose (4c) passing through, and add an electromagnetic water hammer shuttle to facilitate shaking spraying.

The outer cover sliding groove of the impeller is provided with a plurality of rolling bodies (577c). The jujube-like rolling bodies have magnetism for magnetic suspension. They are equipped with the magnetic induction impeller, and two brackets with mechanical friction are eliminated. Magnetic suspension and rolling assistance are used, and the friction is smaller and the accuracy is more accurate. Because the conventional electromagnetic flowmeter with a central axis bracket has two central axis brackets, it is difficult to adjust the concentricity of the two central axes and it is also difficult to detect the gap of the central axis. There are two central axis brackets and each bracket has 3 rods, a total of There are six rods and two bearing pairs, and their huge volume has an impact on the fluid flow and creates resistance in the narrow flow channel, consuming a lot of useless work; the outer surface of the garden hose (3) is a hollow accordion-like folded fiber hose (3a) with a graphene layer inside, and a hollow rubber band tube (3c) with a Shore hardness of 90 degrees is also provided inside the fiber hose (3a) to facilitate retraction and reduce the storage volume; the rectangular plate section (1h) of the garden hose plate (1) is provided with two partitions so that there are three fluid channels that are interconnected, and the rectangular plate surface of the garden hose plate (1) is provided with a plurality of triangular holes (14) to accommodate a plurality of S-shaped spiral spray heads (4);The S-shaped spiral spray head (4) is a similar twisted triangle that spirals upward along a logarithmic spiral to achieve the purpose of spraying water in a spiral manner. The inner flow channel section (4a) of the S-shaped spiral spray head (4) is elliptical to achieve a noise reduction effect when the water mist fluid passes through. The rectangular plate surface of the garden hose plate (1) is also provided with a plurality of approximately pentagonal holes (14c) to accommodate a plurality of the capillary wetting hoses (4c) to facilitate wetting and penetration drip irrigation. The adjustable dripper (55a) extends a cotton fiber line (55y) from the drip port (55x) to facilitate capillary wetting and slower water-saving drip irrigation.

[0005] The remotely controllable pressurized electric sprayer is water-saving and is provided with a plurality of S-shaped spiral spray heads (4) and a capillary wetting hose (4c). The electromagnetic flowmeter (571) has a magnetic induction impeller (579) with one or two blades and a magnetic rolling body (577c) for magnetic suspension.

The capillary wetting hose (4c) is also provided. The adjustable dripper (55a) extends a cotton fiber line (55y) from a dripping port (55x) to facilitate capillary wetting and slower water-saving drip irrigation.

[0006] There is no end to the exploration of improvement and innovation. How can we make the improved self-spraying garden hose more water-saving? The usual self-spraying garden hose sprays water continuously. If it can spray water intermittently, it can save water. If it is made into a complex structure, the cost is high and it is easy to damage. It is hoped that it can spray high and far at once and then stop or reduce it to spray water at short intervals. The effect is good and water-saving. It is a good idea to use the water hammer effect, which can be used for the improved self-spraying garden hose. When the fluid flow is blocked, the fluid in the transmission system will produce irregular water hammer and surge shock waves, thus having a strong shock wave. Thus, a water hammer shuttle control spray head of a self-spraying garden hose was released. In order to enhance the spraying intensity, a portable electric sprayer which is further improved from an improved self-spraying garden hose has come into being. The key point is to add an electric incomplete gear reciprocating pause method to improve the auxiliary support plate (2) from passive assistance to active assistance for the passing S-shaped spiral spray head (4) and the capillary wetting hose (4c) so as to facilitate shaking spraying.

[0007] A remotely controllable pressurized electric sprayer includes an electromagnetic flowmeter (571) connected to a garden hose (3) and a capillary wetting hose (4c). The garden hose (3) is connected to a garden hose plate (1) through a garden hose connector (1a) and a garden hose inlet (1b).

A front overflow port (1by) is provided at one end of the garden hose inlet (1b) close to the piston inner cavity connected to the garden hose connector (1a). The other end of the piston inner cavity of the tube plate (1) is provided with a rear overflow port (1bh). The piston inner cavity of the garden hose inlet (1b) is provided with a water hammer shuttle (1s) that can reciprocate and vibrate. The water hammer shuttle (1s) is slightly in the shape of a weaving shuttle with pointed ends, i.e., a jujube-shaped, so that the water channel can be reciprocated half-open and half-closed at both ends. The water hammer shuttle (1s) is provided with an air bag (1sk) inside so that it can reciprocate and have compression and rebound elasticity and utilize the water hammer effect. When the flow of the fluid is blocked, the fluid in the transmission system generates irregular water hammer waves caused by water hammer and surge, thereby generating strong shock waves. The water hammer effect is used to turn harm into benefit. Under the reciprocating pulsation of the water hammer shuttle (1s), the water from the garden hose plate (1) to the S-shaped spiral spray nozzle is The spraying aerosol of the sprinkler head (4) has a pulsating effect, and at the same time, the capillary wetting of the capillary wetting hose (4c) has an ideal effect of pulsating squeeze drip irrigation; on the basis of the above, in order to strengthen the spraying intensity, a remotely controllable pressurized electric sprinkler was trial-produced, the key point of which is to add an electric incomplete gear reciprocating pause method, so that the auxiliary support plate (2) improves the passive assistance to the S-shaped spiral sprinkler head (4) and the capillary wetting hose (4c) passing through to active assistance, which is beneficial to the shaking spraying.

[0010] Benefits:

[0011] A remotely controllable pressurized electric sprayer and a garden hose can save water by spraying water intermittently. It is desirable to spray water high and far at once and then pause or reduce the water at once. The spraying water is sprayed intermittently with short intervals. The effect is good and water is saved. A thousand considerations are worth a thousand tricks. It is thought that the water hammer effect is used. When the flow of fluid is blocked, the fluid in the transmission system generates irregular water hammer and surge shock waves. The strong shock wave is used to set a water hammer shuttle device. The water hammer shuttle in the piston inner cavity of the garden hose inlet (1b) reciprocates the half-open and half-closed water channel. An air bag (1sk) is arranged inside the water hammer shuttle (1s) to facilitate the reciprocating compression rebound elasticity and the use of the water hammer effect. The auxiliary support plate (2) is used to control the S-shaped spiral spray head (4) and the capillary wetting hose ( 4c) not only assists but also the incomplete gear (2f) driven by the motor rotates to alternately mesh with the upper and lower racks (2c) of the auxiliary support plate (2) to actively assist, so that the auxiliary support plate (2) has a reciprocating short-distance movement and a short pause at both ends, so that the S-shaped spiral spray head (4) and the capillary wetting hose (4c) passing through are swung, and the reciprocating elasticity of the water hammer shuttle (1s) that can reciprocate and vibrate and the water hammer effect are used. Under the reciprocating pulsation and reciprocating short-distance movement, the spray mist through the garden hose plate (1) to the S-shaped spiral spray head (4) and the capillary wetting hose (4c) has a pulsating vibration effect, and the capillary wetting of the capillary wetting hose (4c) has an ideal effect of pulsating squeeze drip irrigation. The auxiliary support plate (2) is installed above the garden hose inlet (1b) and the garden hose plate (1). The auxiliary support plate (2) is provided with two parallel and substantially mirror-image upper and lower racks (2c) of the same modulus, which are alternately meshed with an incomplete gear (2f) driven by a battery-driven motor when rotating. The number of teeth of the incomplete gear (2f) is not more than three, so that the auxiliary support plate (2) has a short reciprocating movement and a short stop at both ends, so as to swing through the The S-shaped spiral spray head (4) and the capillary wetting hose (4c) cooperate with the reciprocating compression and rebound elasticity of the water hammer shuttle (1s) that can reciprocate and vibrate in the piston cavity of the garden hose inlet (1b) and utilize the water hammer effect, so that under the reciprocating pulsation and reciprocating short-distance movement, the spray mist through the garden hose plate (1) to the S-shaped spiral spray head (4) and the capillary wetting hose (4c) has a pulsating vibration effect and the capillary wetting of the capillary wetting hose (4c) has an ideal effect of pulsating squeeze drip irrigation. The outside of the garden hose (3) is a hollow accordion-like folded fiber hose (3a) with a graphene layer attached thereto, and a hollow rubber band tube (3c) with a Shore hardness of 90 degrees is arranged inside the fiber hose (3a) to facilitate retraction and reduce the storage volume. The dual effects of utilizing electromagnetic induction of a self-excited multivibrator and utilizing the water hammer effect make the water hammer shuttle (1s) equipped with a movable magnetic ball (1sm) more conducive to shaking spraying.A two-color light emitting diode (LED2) is also arranged in the self-excited multivibrator to achieve a light-emitting, shaking and spraying viewing effect.

Due to the double-press valve core structure (p1) that pulls and pushes, the pushing pressure is relatively large and reliable. The water in the pump chamber pushes open the parabolic plug (p3), passes through the enlarged flow channel (p4) under the thread of the sleeve with enlarged aperture, and then passes through the fine-adjustable spiral plug (p5) with the enlarged flow channel, and then flows at a relatively large pressure. The liquid flows out of the pump through the threaded port; when the valve core is sucked back again, the overflow valve composed of the large lateral hole in the middle of the valve core and the small compression spring has the function of buffering and preventing negative pressure; the plug (p3) is equivalent to a one-way valve and is closed, and this cycle repeats; the remote-controllable pressurized electric sprayer can be remotely controlled by any existing infrared remote controller that can remotely control a TV set to remotely control the electromagnetic pump F of the remote-controllable pressurized electric sprayer, and is characterized in that it is not only provided with an electromagnetic pump F on the spraying water path, but also with an infrared light receiving circuit; any existing infrared remote controller that can remotely control a TV set can be used to send signals to the infrared light receiving circuit; the infrared light receiving circuit The load of the unidirectional thyristor VTH provided in the circuit is the electromagnetic pump F; the unidirectional thyristor VTH, the diode VD2-5 and the electromagnetic pump F form the main circuit of the remote control, so that when the unidirectional thyristor VTH integrated circuit loses the trigger voltage, the AC power is turned off when it passes through zero; the infrared receiving tuning amplifier A1 adopts the infrared amplification dedicated circuit μPC1373, and is also provided with a buffer inverter A2 using an ordinary six-inverter digital integrated circuit CD4069. As long as two of the inverting gates are intact, the input end of the other unused inverting gates should be grounded, and should not be left hanging to avoid interference; the dimming amplifier A3 adopts the dimming dedicated integrated circuit HT7700A;When the infrared receiving diode VD1 receives the signal from the modulated infrared light receiving circuit of the infrared remote control transmitter, the infrared receiving tuned amplifier A1 uses the infrared amplification dedicated circuit μPC1373, and its output pin 1 changes from the original high level to a low level. After being buffered and amplified by the two-stage inverter A2, the output low-level control signal is directly added to the keying signal input terminal of the dimming dedicated integrated circuit A3, that is, the second pin, to control the operation of A3. The working characteristic of the dimming amplifier A3 is that when the low level time of pin 2 is less than 0.7 seconds, it is in the switch working state, that is, pressing the infrared remote control transmitter launch button for less than 0.7 seconds can realize the on or off operation; if the low level appears When the time is greater than 0.7 seconds, it is in the adjustment state, that is, it can be adjusted; when the 2nd foot of A3 returns to the high level, the conduction degree of the unidirectional thyristor VTH is fixed; so if the key press time is greater than 0.7 seconds, it can be adjusted, and the conduction degree is set when the launch button is released; if the key press time is less than 0.7 seconds, it can be turned off; one end of R15 is directly connected to 220 volts AC, which provides AC synchronization signal for A3; R16 is the external oscillation resistor of A3; the 5th foot of A3 is the pulse output end, which outputs the trigger pulse to manipulate the load of the unidirectional thyristor VTH provided in the infrared light receiving circuit, that is, the electromagnetic pump F to pressurize the water circuit to form a remotely controllable pressurized electric sprayer. ;

[0086] The operator must connect the water supply hose, power supply and remote control before use.

[0087] There is no end to the exploration of improvement and innovation. How can we make the improved portable electric sprinkler more water-saving? The usual self-spraying garden hose sprays water continuously. If it can spray water intermittently, it can save water. If it is made into a complex structure, the cost is high and it is easy to damage. It is hoped that it can spray high and far at once and then stop or reduce it to spray water at short intervals. The effect is good and water-saving. It is a good idea to use the water hammer effect to improve the self-spraying garden hose. When the fluid flow is blocked, the fluid in the transmission system will produce irregular water hammer waves caused by water hammer and surge, thus having a strong shock wave. Thus, a water hammer shuttle control sprinkler head of a self-spraying garden hose was released. In order to enhance the spraying intensity, a portable electric sprayer which is further improved from an improved self-spraying garden hose has come into being. The key point is to add an electric incomplete gear reciprocating pause method to improve the auxiliary support plate (2) from passive assistance to active assistance for the passing S-shaped spiral spray head (4) and the capillary wetting hose (4c) so as to facilitate shaking spraying.

[0088] The improved portable electric sprayer comprises an electromagnetic flowmeter (571) connected to a garden hose (3) and a capillary wetting hose (4c), wherein the garden hose (3) is connected to a garden hose plate (1) through a garden hose connector (1a) and a garden hose inlet (1b), and the garden hose plate (1) is provided with a plurality of S-shaped spiral spray heads (4). The highlight of the invention is that a water hammer shuttle device is provided between the garden hose inlet (1b) and the garden hose plate (1), and a water hammer shuttle device is provided between the garden hose inlet (1b) and the garden hose plate (1). A front overflow port (1by) is provided at one end of the piston inner cavity of the hose connector (1a), and a rear overflow port (1bh) is provided at the other end of the piston inner cavity of the garden hose inlet (1b) close to the garden hose plate (1). A water hammer shuttle (1s) capable of reciprocating vibration is provided in the piston inner cavity of the garden hose inlet (1b). The water hammer shuttle (1s) is slightly in the shape of a weaving shuttle with pointed ends, i.e., a jujube-shaped, so that the water channel can be reciprocated half-opened and half-closed at both ends. An air bag (1sk) is provided inside the water hammer shuttle (1s) so that the water hammer shuttle (1s) can reciprocate and compress the water back and forth. By utilizing the elasticity and water hammer effect, when the fluid flow is blocked, the fluid in the transmission system generates irregular water hammer and surge shock waves, thereby generating strong shock waves. By utilizing the water hammer effect, harm is turned into benefit. Under the reciprocating pulsation of the water hammer shuttle (1s), the spray mist from the garden hose plate (1) to the S-shaped spiral spray head (4) has a pulsating effect, and at the same time, the capillary wetting of the capillary wetting hose (4c) has an ideal effect of pulsating squeeze drip irrigation. On the basis of the above, in order to enhance the spraying intensity, a portable electric sprayer comes into being. The main point is to add an electric incomplete gear reciprocating pause method, so that the auxiliary support plate (2) improves the passive support to the S-shaped spiral spray head (4) and the capillary wetting hose (4c) passing through to active support, which is beneficial to the shaking spraying. The portable electric sprayer is an application of a water-saving method, which includes an electromagnetic flow meter (571), a garden hose (3), a garden hose plate (1), an auxiliary support plate (2), an S-shaped spiral spray head (4), a capillary wetting hose (4c), an adjustable dripper (55a), upper and lower racks (2c), and an incomplete gear (2f);One end of the electromagnetic flowmeter (571) is a water inlet, and the other end of the electromagnetic flowmeter (571) is connected to the garden hose (3) and the capillary wetting hose (4c). The garden hose (3) is connected to the garden hose plate (1) through a garden hose connector (1a) and a garden hose inlet (1b). The garden hose plate (1) is provided with a plurality of S-shaped spiral spray heads (4). The garden hose plate (1) is also provided with a plurality of capillary wetting hoses (4c). The auxiliary support plate (2) supports the S-shaped spiral spray heads (4) and the capillary wetting hoses (4c) passing through. The portable electric sprayer has the following highlights: Installed above the garden hose inlet (1b) and the garden hose plate (1), the auxiliary support plate (2) is provided with two parallel and roughly mirror-image upper and lower racks (2c) of the same modulus, which are alternately meshed with an incomplete gear (2f) driven by a battery-driven motor when rotating, and the number of teeth of the incomplete gear (2f) is not more than three, so that the auxiliary support plate (2) has a reciprocating short-distance movement and a short pause at both ends. Under the reciprocating pulsation and reciprocating short-distance movement, the spray mist through the garden hose plate (1) to the S-shaped spiral spray head (4) and the capillary wetting hose (4c) has a pulsating vibration effect, and the capillary wetting of the capillary wetting hose (4c) has an ideal effect of pulsating squeeze drip irrigation. The outside of the garden hose (3) is a hollow accordion-like folded fiber hose (3a) with a graphene layer inside, and a hollow rubber band tube (3c) with a Shore hardness of 90 degrees is arranged inside the fiber hose (3a) to facilitate retraction and reduce the storage volume.

[0089] The improved portable electric sprayer has the following highlights: a movable magnetic ball (1sm) is arranged inside an air bag (1sk) inside a water hammer shuttle (1s) that can reciprocate and vibrate in the piston cavity of a garden hose inlet (1b); and an electromagnetic coil (1e) is arranged outside the garden hose inlet (1b); the oscillating electromagnetic field of the electromagnetic coil (1e) affects the movable magnetic ball (1sm), thereby affecting the reciprocating water hammer shuttle (1s), and further affecting the vibration of the S-shaped spiral spray head (4) to spray aerosol and water mist of the capillary wetting hose (4c). Fluid pulsation, so as to utilize electromagnetic induction of the self-excited multivibrator and water hammer effect to make the water hammer shuttle (1s) with the movable magnetic ball (1sm) more conducive to shaking spraying; a two-color light emitting diode (LED2) is also arranged in the self-excited multivibrator to achieve the viewing effect of luminous shaking spraying; the self-excited multivibrator circuit includes a first transistor VT1 and a second transistor VT2, the first pulse interval is about 0.7*R3*C2, the second pulse interval is about 0.7*R2*C1, and also includes resistors R1-5, capacitors C1-2, and indicator LED 1, two-color light-emitting diode LED2, battery CELL; after the battery CELL is installed and powered on, the collector levels of the first transistor VT1 and the second transistor VT2 always alternate between high level and low level. The two-color light-emitting diode (LED2) has two light-emitting tube cores, red and green, connected in reverse parallel, and has only two pins to the outside, and does not distinguish between positive and negative polarities; of the two parallel tube cores, the upper one is the red tube core, and the lower one is the green tube core. When the first transistor VT1 is turned on, its collector is at a low level, and the second transistor VT2 is turned off. The collector outputs a high level, so not only the tube core above is energized to emit light, but also the electromagnetic coil (1e) is energized to generate an oscillating electromagnetic field that affects the movable magnetic ball (1sm), thereby affecting the reciprocating water hammer shuttle (1s), and further affecting the vibration spraying of the S-shaped spiral spray head (4) and the pulsation of the water mist fluid of the capillary wetting hose (4c), and vice versa, over and over again, using the dual effects of the electromagnetic induction of the self-excited multivibrator and the water hammer effect to make the water hammer shuttle (1s) with the movable magnetic ball (1sm) more conducive to shaking spraying.
