Description

Technical Field

[0001] The invention relates to the technical field of atomizing devices, in particular to a sprayer with a spray water content regulating function. Background Art

[0002] Sprayer is the abbreviation of spray equipment, which refers to an instrument that extracts liquid from a barrel and sends it to a nozzle for atomization, and then sprays it evenly onto other objects. According to the working mode, it can be divided into manual sprayer and electric sprayer. When using existing manual sprayers or electric sprayers, the water and medicine in the sprayer barrel are usually stirred manually. The stirring operation process is cumbersome, inefficient, and labor-intensive, which affects work efficiency. In addition, the spray drive system of the electric sprayer is single. When the spray drive system is damaged, there is no temporary replacement drive system, which means that the sprayer can only be replaced or repaired before use, which seriously affects the progress of the spray operation. Summary of the invention

[0003] The object of the present invention is to provide a sprayer with a spray water content regulating function to solve the problems raised in the prior art.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sprayer with a function of adjusting the water content of a spray, comprising a barrel body, a handle and a nozzle, wherein a nozzle is installed at the output end of the nozzle, and further comprising a barrel seat, wherein the barrel seat is installed at the bottom of the barrel body, an electric drive mechanism is installed inside the barrel seat, a transmission pipe is installed at the output end of the electric drive mechanism, an air pipe is inserted inside the transmission pipe, and the electric drive mechanism transports liquid medicine and gas to the transmission pipe and the air pipe respectively, a handle is sleeved on one end of the transmission pipe, an adjusting mechanism for adjusting the flow rate of liquid medicine is installed on the handle, the adjusting mechanism connects the transmission pipe and the air pipe, an opening and closing valve is installed at the output end of the adjusting mechanism, and the nozzle is installed at the output end of the opening and closing valve.

[0005] The bottom of the barrel body is a bottom plate, the bottom plate is provided with a perforation, a mixing fan is rotatably installed in the perforation, an isolation cover is installed on the outside of the perforation of the bottom plate, a water bucket is installed on the outside of the perforation below the bottom plate, and a water pipe is installed at the contraction part of the water bucket;

[0006] The electric drive mechanism includes a water pump connected in series in the water pipe, a plurality of parallel micro air pumps for pumping gas, and a controller, the output end of the water pipe is connected to the transmission pipe, the micro air pump is connected to the air pipe, a one-way valve is connected in series on the air pipe that does not extend into the transmission pipe, and the water pump and the micro air pump are connected to the controller;

[0007] A plurality of switches and charging ports are installed on one side of the barrel seat, and the plurality of switches and charging ports are connected to the controller. The switch is used to start and stop the sprayer, and the controller controls the operation of the entire sprayer. The isolation cover (not shown in the figure) is used to isolate impurities in the liquid medicine. The one-way valve allows the gas to flow into the regulating mechanism in one direction and prevents the liquid medicine from flowing through the air pipe to the micro air pump.

[0008] The regulating mechanism includes a pressure-regulating tube connected to the handle, and two concentric connecting rings with different diameters are arranged at the input end of the pressure-regulating tube, the outer connecting ring is connected to the transmission tube, and the inner connecting ring is connected to the air pipe. An annular regulating chamber and a water chamber are axially arranged inside the pressure-regulating tube, an regulating plate is rotatably installed in the regulating chamber, a plurality of through holes are arranged between the regulating chamber and the water chamber, and secondary holes adapted to the through holes are arranged on the regulating plate. Openings penetrating the regulating chamber are symmetrically arranged on the pressure-regulating tube, a retaining ring and an adjusting ring are rotatably installed on the outer side of the pressure-regulating tube, the adjusting ring covers the outer side of the opening, and the adjusting ring is connected to the adjusting plate through a support rod. A negative pressure hole connected to the inner flow channel of the pressure-regulating tube is arranged on the inner side of the water chamber, the inner flow channel diameter of the pressure-regulating tube shrinks from the middle, and the diameter of the inner flow channel input port is larger than the diameter of the output port. When only the water pump is used, the water pump pumps the mixed liquid medicine into the water pipe. The liquid medicine flows into the pressure regulating pipe along the water pipe, enters the water cavity after passing through the regulating plate and the through hole, and flows to the opening and closing valve and the nozzle through the negative pressure hole. Under the pumping pressure of the water pump, a high-speed water flow is formed in the nozzle, and the liquid medicine is sprayed out through the nozzle in atomization. When only the micro air pump is used (the water pump is not working and does not affect the liquid medicine flowing through the water pump), the micro air pump pumps the gas into the air pipe. When the gas flows into the inner flow channel of the pressure regulating pipe, the gas increases the pressure in the middle of the inner flow channel, and reduces the pressure and speeds up in the process of flowing to the output port. When the high-flow gas passes through the negative pressure hole, the pressure inside the water cavity decreases. Under the action of air pressure, the liquid medicine in the barrel flows into the water pipe, flows through the water pump and enters the transmission pipe, and finally flows into the water cavity of the pressure regulating pipe. The liquid medicine in the water cavity flows into the inner flow channel of the pressure regulating pipe and flows into the nozzle together with the gas. When the water pump and the micro air pump work synchronously, the water pump and the micro air pump are used in conjunction with each other. When only a micro air pump or a water pump is used in conjunction with a micro air pump, when the sprayer is turned off, it is necessary to adjust the content of the liquid medicine in the gas, turn the adjustment ring, and the adjustment ring drives the adjustment plate to rotate through the support rod to reduce the overlapping area of ​​the auxiliary hole and the through hole until there is no overlap and it is zero. When the micro air pump and the water pump are used in conjunction with each other, before turning off the sprayer, first turn the adjustment ring so that the auxiliary hole no longer overlaps with the through hole, and the transmission tube is isolated from the water cavity. After that, the pressure sensor transmits the pressure data to the controller. The controller stops the water pump according to the increased pressure, and the micro air pump continues to supply air, using the airflow to spray the liquid medicine in the nozzle, preventing the liquid medicine from being retained in the nozzle, and preventing the substances in the liquid medicine from clogging the nozzle, and finally close the switch and the on-off valve. When only the micro air pump is used, when the sprayer needs to be closed, first turn the adjustment ring so that the secondary hole no longer overlaps with the through hole, separate the transmission tube from the water cavity, and prevent the liquid medicine from continuing to enter the water cavity. Then the micro air pump delays work for a certain period of time and uses the airflow to spray out the liquid medicine in the nozzle to prevent the liquid medicine from being retained in the nozzle. Finally, close the switch and the on-off valve.

[0009] The output end of the water pump is equipped with a pressure sensor, which is connected to the controller. The pressure sensor is used to monitor the pressure at the output end of the water pump. When the adjustment ring is rotated to reduce the overlapping area between the auxiliary hole and the through hole, the pressure of the liquid medicine flowing into the water cavity increases, thereby increasing the pressure in the water pipe and the transmission pipe. The pressure sensor monitors the pressure increase and transmits the data to the controller, which adjusts the working speed of the water pump according to the pressure change.

[0010] The bottom plate is provided with a perforation at the center position, in which a central tube is rotatably installed, a driven wheel is installed below the central tube, a driving disk is installed on one side of the central tube below the bottom plate, a driving wheel is installed at the output end of the driving disk, the driving wheel and the driven wheel are meshed for transmission, a stirring rod is provided on the central tube, and a side plate is provided on the stirring rod. After the medicine and water are added to the barrel, the switch is turned on, and the controller makes the driving disk work, and the driving disk drives the central tube to rotate through the driving wheel and the driven wheel, and the stirring rod stirs the water and medicine driven by the central tube to fully mix the medicine and water. The stirring rod, the central tube and the driving disk form a mixing mechanism to achieve mixing and stirring of the medicine and water, replacing the manual stirring process.

[0011] An elliptical track is arranged in the middle of the bottom plate, and the perforation is located at the center of the track. A carrier ring is arranged on the central tube located above the bottom plate, and two multi-stroke telescopic plates are symmetrically mounted on the carrier ring. A base is installed at the end of the telescopic plate, and two rollers are rotatably mounted under the base, and the two rollers are distributed on both sides of the track; the number of the stirring rods is two and they are respectively mounted on two bases. When the driving disc drives the central tube to rotate, the central tube drives the two telescopic plates to rotate through the carrier ring, and the base moves under the drive of the telescopic plate. Under the cooperation of the track, the roller and the base, the telescopic plate is continuously extended and retracted during the rotation process, and the stirring rod realizes the stirring and mixing of the medicine and water in the process of following the movement of the base.

[0012] The stirring rod is rotatably mounted on the base, and a rudder is mounted on the stirring rod. When the stirring rod moves along with the base, the rudder constantly changes the posture of the stirring rod in the moving direction of the stirring rod under the impact of the water flow, so that the stirring rod can effectively use the side plate to stir and mix the medicine and water.

[0013] The central tube is a hollow structure, and a gas-supplementing hole is provided at the center of the upper end of the central tube. A sleeve is sleeved below the central tube, and the sleeve is located below the driven wheel. One end of the sleeve is mounted on the barrel seat, and the sleeve is connected to the air pipe through a pipeline connected in series with a throttle valve. During the operation of the micro air pump, gas is supplied to the sleeve through the pipeline and the throttle valve, so that the gas enters the barrel body through the gas-supplementing hole of the central tube to compensate for the low pressure caused by the drop of the liquid medicine.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The driving disc drives the central tube to rotate through the driving wheel and the driven wheel. The stirring rod is driven by the central tube to stir the water and medicine so that the medicine and water are fully mixed. The stirring rod, the central tube and the driving disc form a mixing mechanism to achieve the mixing and stirring of the medicine and water, replacing the manual stirring process.

[0016] 2. Combining the Bernoulli principle with the principle that high-speed water flow breaks into small droplets after hitting an obstacle, two spray drive systems (i.e., water pump drive and micro air pump drive) are used. During use, when the drive system in use fails, the other system can temporarily replace the system in use to complete the spray work. The combination of two spray drive systems solves the problem that the spray work cannot be completed due to damage to a single spray drive system.

[0017] 3. When using a micro air pump or when using a micro air pump and a water pump in conjunction with each other, before closing the sprayer, first turn the adjustment ring so that the secondary hole no longer overlaps with the through hole, and separate the transmission tube from the water cavity. Then, use the airflow supplied by the micro air pump to spray the liquid in the nozzle to prevent the liquid from being retained in the nozzle and the substances in the liquid from clogging the nozzle. Finally, close the switch and the on-off valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] An elliptical track 29 is provided in the middle of the bottom plate 7, and the perforation is located at the center of the track 29. A carrier ring is provided on the central tube 20 located above the bottom plate 7, and two multi-stroke telescopic plates 19 are symmetrically installed on the carrier ring. A base 17 is installed at the end of the telescopic plate 19, and two rollers 18 are rotatably installed under the base 17. The two rollers 18 are distributed on both sides of the track 29;

[0036] There are two stirring rods 9 which are respectively mounted on two bases 17 . A side plate 16 is provided on the stirring rod 9 . The stirring rod 9 is rotatably mounted on the base 17 . A steering plate 15 is mounted on the stirring rod 9 .

[0037] Working principle of the present invention:

[0038] Open the lid, take out the filter, add the medicine and water to the barrel body 1, then replace the filter and cover the lid. Press the switch for mixing and stirring on the side of the barrel seat 2, and the controller will make the driving disk 10 work. The driving disk 10 drives the central tube 20 to rotate through the driving wheel and the driven wheel 22. The stirring rod 9 stirs the water and medicine under the drive of the central tube 20 to fully mix the medicine and water. When the driving disk 10 drives the central tube 20 to rotate, the central tube 20 drives the two telescopic plates 19 to rotate through the carrier ring, and the base 17 moves under the drive of the telescopic plates 19. Under the cooperation of the track 29, the roller 18 and the base 17, the telescopic plates 19 are continuously extended and retracted during the rotation process, and the stirring rod 9 realizes the stirring and mixing of the medicine and water in the process of following the movement of the base 17.

[0039] After the mixing is completed, put the sprayer on your back and turn on another switch for spraying again. You can press any of the three mode switches. When only the water pump 23 is used, the water pump 23 pumps the mixed liquid medicine into the water pipe 13. The liquid medicine flows along the water pipe 13 into the pressure regulating pipe 25, passes through the regulating plate 27 and the through hole, enters the water cavity 28, and flows to the opening and closing valve 4 and the nozzle 5 through the negative pressure hole. Under the pumping pressure of the water pump 23, a high-speed water flow is formed in the nozzle 5, and the liquid medicine is sprayed out through the nozzle in atomization.

[0040] When only the micro air pump 8 is used, the micro air pump 8 pumps the gas into the air pipe 14. When the gas flows into the inner flow channel of the pressure regulating tube 25, the gas is pressurized in the middle of the inner flow channel, and the pressure is reduced and the speed is increased in the process of flowing to the output port. When the high-flow rate gas passes through the negative pressure hole, the internal pressure of the water cavity 28 is reduced. Under the action of air pressure, the medicine liquid in the barrel body 1 flows into the water pipe 13, flows through the water pump 23 and enters the transmission pipe 3, and finally flows into the water cavity 28 of the pressure regulating tube 25. The medicine liquid in the water cavity 28 flows into the inner flow channel of the pressure regulating tube 25 and flows into the nozzle 5 together with the gas.

[0041] When the water pump 23 and the micro air pump 8 work synchronously, the water pump 23 and the micro air pump 8 cooperate with each other.

[0042] When only the micro air pump 8 or the water pump 23 is used in conjunction with the micro air pump 8, when the sprayer is turned off, it is necessary to adjust the content of the liquid medicine in the gas, and rotate the adjustment ring 26. The adjustment ring 26 drives the adjustment plate 27 to rotate through the support rod to reduce the overlapping area between the auxiliary hole and the through hole. When the adjustment ring 26 is rotated to reduce the overlapping area between the auxiliary hole and the through hole, the pressure of the liquid medicine flowing into the water cavity 28 increases, thereby increasing the pressure in the water pipe 13 and the transmission pipe 3. The pressure sensor monitors the pressure increase and transmits the data to the controller, and the controller adjusts the working speed of the water pump 23 according to the pressure change.

[0043] When the micro air pump 8 and the water pump 23 are used in conjunction with each other, before closing the sprayer, first rotate the adjustment ring 26 so that the secondary hole no longer overlaps with the through hole, and the transmission tube 3 is isolated from the water chamber 28. After that, the pressure sensor transmits the pressure data to the controller. The controller stops the water pump 23 according to the increased pressure, and the micro air pump 8 continues to supply air, and uses the airflow to spray out the liquid medicine in the nozzle 5 to prevent the liquid medicine from being retained in the nozzle 5 and to prevent the substances in the liquid medicine from clogging the nozzle. Finally, the switch and the on-off valve 4 are closed.

[0044] When only the micro air pump 8 is used, when the sprayer needs to be closed, first turn the adjustment ring 26 so that the secondary hole no longer overlaps with the through hole, and the transmission tube 3 is separated from the water cavity 28, so that the liquid medicine can no longer continue to enter the water cavity 28. Then the micro air pump 8 delays working for a certain period of time, and uses the airflow to spray out the liquid medicine in the nozzle 5 to prevent the liquid medicine from being retained in the nozzle 5. Finally, close the switch and the on-off valve 4.

[0045] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
