The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a back pressure boosting type sprayer includes a housing 1 for containing a chemical solution. The bottom of the shell 1 is provided with an electric pump for discharging liquid, and corresponding liquid discharging holes 2 are arranged to be connected with a spray pipe for spraying liquid medicine on crops. The other side of the shell 1 is provided with a handle 3, and a corresponding switch can be arranged on the handle 3 for controlling the operation of the electric pump.
As shown in fig. 3 and 4, in order to increase the pressure of the liquid medicine in the housing 1, so as to reduce the driving difficulty of the liquid medicine when the electric pump drives the spraying of the liquid medicine, a plurality of pressing air bags 4 are respectively arranged on two sides of the back of the housing 1. The pressing airbag 4 is arranged on the shell 1 and communicated with the shell 1. The position of the back muscle of the user corresponding to the pressing air bag 4 is specifically the latissimus dorsi, trapezius, or rhomboid muscle. When a person walks, the muscle components are in a continuous reciprocating telescopic motion state, so that the walking process of the person is supported. During the extension and contraction of the muscles, the compression balloon 4 is continuously compressed and restored.
A communication pipe 5 is provided between adjacent ones of the pressing airbags 4 in a row of the pressing airbags 4 for connecting the respective pressing airbags 4 so that the gas inside the pressing airbags 4 runs in the same system. One side of the pressing air bag 4 at the top is communicated with an output pipe 6. The output pipe 6 is a hard pipe and is transversely arranged in the shell 1. One end of the output pipe 6 is communicated with a corrugated hose 7. The bottom of the corrugated hose 7 is provided with a pressing plate 8. The pressing plate 8 abuts against the piston 9. The piston 9 is slidably disposed in the housing 1. A column 10 is arranged in the middle of the piston 9. The upright 10 is used to provide support and guidance for the piston 9 to slide up and down so that the piston 9 slides up and down on the upright 10.
In the above process, the pressing airbag 4 is driven to compress when the person walks, and at this time, the gas in the pressing airbag 4 is communicated with each other along the communicating pipe 5 and finally enters the bellows 7 through the output pipe 6. The bellows 7 expands and opens the bellows, the hose exhibiting an increased length, thereby exerting pressure on the platen 8, and the liquid level of the liquid medicine below the piston 9 gradually decreases when the liquid medicine is sprayed, at which time, under the pushing action of the platen 8, the platen 8 pushes the piston 9 downward and maintains a larger pressure on the top of the liquid medicine.
After the liquid medicine is sprayed, one side of the shell 1 is also provided with a liquid inlet 11. The piston 9 is manually pushed to a position beyond the liquid inlet 11, and liquid is fed into the liquid inlet 11, so that the liquid medicine is continuously injected below the piston 9, and the purpose of adding the liquid medicine is achieved.
Above-mentioned, through the form that the user walked or moved promotes to press the reciprocating type of gasbag 4 to aerify and gassing, thereby promote the piston 9 removal of gasbag one side, piston 9 removes the liquid medicine that promotes to be in piston 9 below, thereby increase the inside pressure of atomizer, make the atomizer still have the pressure to promote on the basis of charge pump drive, thereby reduce the electric energy consumption, improve battery duration.
The application also provides another driving mode, which is specifically as follows:
as shown in fig. 5, 6 and 7, the pressing airbag 4 at the top is connected to a fixing tube 12. One end of the fixed tube 12 is provided with a corrugated hose 7. An abutment plate 13 is provided at one end of the bellows 7. One end of the abutting plate 13 is connected with a pawl 14, the pawl 14 is hinged with the abutting plate 13, a spring is arranged between the pawl 14 and the abutting plate 13 and used for resetting the pawl 14, and a baffle 15 is arranged on one side of the pawl 14. So that the pawl 14 can only rotate to one side and the other side is limited by the baffle 15 and cannot rotate.
The column 10 is provided as a screw 16 corresponding to the direction of movement of the pawl 14. A ratchet wheel 17 is fixedly arranged on the screw rod 16. When the user walks pushing the pressing airbag 4 to reciprocally inflate or deflate, the bellows 7 is caused to exhibit a reciprocal increase or decrease in length, i.e., the bellows 7 is caused to expand or contract, thereby pushing the abutment plate 13 to reciprocally move. The pawl 14 on the abutment plate 13 cooperates with the ratchet 17, and each reciprocation drives the ratchet 17 to rotate one tooth, thereby causing the screw 16 to continue to rotate.
The screw 16 is screwed with a ball screw seat 18. The upper side and the lower side of the ball screw seat 18 are connected through sealing rings, so that the liquid medicine can not enter the upper side of the piston 9 along the gap between the ball screw seat 18 and the screw 16. The ball screw seat 18 is connected with the piston 9 and enables the piston 9 to be limited by the shell 1. In the process of continuous rotation of the screw 16, the balls in the ball screw seat 18 work in the screw groove of the screw 16, so that the ball screw seat 18 is driven to move downwards, the piston 9 is driven to move downwards, the continuous compression of the liquid level is kept, the pressure of the liquid level in the sprayer is increased, the bottom of the liquid medicine is pushed to enter the spray pipe in advance when the electric pump is started, the flowing path of the liquid medicine is shorter when the electric pump is started, the electric energy consumption is reduced, and the battery cruising ability is improved.
Preferably, with respect to the liquid inlet 11, a water inlet 19 on the same vertical plane as the liquid inlet 11 is arranged on one side of the bottom of the shell 1. The water inlet 19 is closed during use of the nebulizer with a plunger. A plurality of stirring rods 20 are arranged at the bottom of the screw 16 and close to the periphery of the water inlet 19. The screw 16 continuously rotates in each reciprocating type inflation and deflation process of the pressing air bag 4, so that the stirring rod 20 continuously rotates along with the reciprocating type inflation and deflation process, and the liquid medicine at the bottom is stirred, so that the mixing degree of the medicine in water is increased, and a uniform spraying effect is achieved when the liquid medicine is sprayed.
In addition, when the liquid medicine is completely sprayed, the inside of the housing 1 needs to be cleaned. At this time, the piston 9 is located at the upper side of the water inlet 19, the plunger is opened, clean water is input into the water inlet 19 through the water pipe, and the stirring rod 20 reversely rotates under the impact of the clean water due to the fast flow speed of the clean water, and the water flow direction is specifically guided through the shape setting of the stirring rod 20. The stirring rod 20 is rotated in the reverse direction so that the screw 16 is rotated in the reverse direction. The screw 16 drives the piston 9 to move upwards until the clear water fills the shell 1, so that the residual components of the liquid medicine are fused into the clear water, the clear water can be continuously used for spraying, and the clear water can be discharged by an electric pump or a plunger piston is opened, so that a better cleaning effect is achieved. At this point, the piston 9 is still at its highest and the liquid inlet 11 is located below the piston 9, and liquid medicine is added to the liquid inlet 11 for the subsequent spraying process.
The whole working flow comprises the following steps:
1. in the initial state, the piston 9 is positioned at one side of the top of the sprayer, and the liquid level of the liquid medicine in the sprayer gradually drops along with the liquid medicine spraying driven by the electric pump.
2. In this process, as the user walks or moves, the back of the user is continuously reciprocally abutted and separated with the pressing airbag 4, so that the gas in the pressing airbag 4 is inputted into the bellows 7, and the bellows 7 is continuously stretched and contracted. The pushing pawl 14 is matched with the ratchet wheel 17, and the ratchet wheel 17 is pushed each time to rotate by a tooth distance;
3. the piston 9 continuously moves downwards under the action of the ball screw seat 18 to squeeze the liquid medicine, so that the pressure of the liquid medicine is increased, and the endurance of the battery is improved;
4. after the liquid medicine is completely discharged, the plunger is opened, clean water is filled into the plunger, the piston 9 gradually moves upwards, and the housing 1 is filled with the clean water, so that the cleaning effect is achieved;
5. after the clear water is discharged, the plunger is closed, and the liquid medicine is injected into the liquid inlet 11 for the next round of spraying process.
The wall surface of the shell 1 is arranged at right angles to the horizontal plane.
The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.
