Technical Field
[0001] This technical solution relates to the field of sprayer technology, and specifically refers to a sprayer. Background Technology
[0002] A sprayer is a device that turns pesticides or other liquids into a mist for spraying. It is used in agriculture (spraying pesticides and fertilizers). Through nozzles or atomizers, it can efficiently cover the target surface or promote the absorption and diffusion of substances, achieving fine dispersion and uniform distribution of liquids.
[0003] For example, Chinese patent CN109042600A discloses an electric agricultural sprayer, which includes a box body with a medicine inlet at the top and a partition at the bottom. A water pump and a lithium battery are located below the partition. One end of the water pump is connected to a medicine inlet pipe that extends into the inside of the box body, and the other end is connected to a medicine outlet pipe located on the outside of the box body. A stirring cover is located at the top of the box body, and a stirring rod that extends into the inside of the box body is connected below the stirring cover. The stirring rod is equipped with stirring blades. During operation, the stirring rod needs to be swung to mix the medicine and water evenly through the stirring blades.
[0004] The pesticide formulations that can be contained in the casing of the aforementioned electric agricultural sprayers are often mixtures containing solid particles (such as wettable powders, suspensions, etc.). Under the influence of gravity, the particles tend to settle after the sprayer has been standing for a period of time, resulting in a higher concentration at the bottom and uneven concentration distribution. In order to avoid poor fertilization spraying effect, the above-mentioned stirring method requires manual operation of the stirring cover and stirring rod to stir the mixed solution. It is difficult to maintain uniformity during continuous spraying, and frequent intermittent stirring is required, which affects work efficiency and is inconvenient to use. Summary of the Invention
[0005] This technical solution addresses the problem in existing sprayers where frequent pauses for manual stirring are necessary due to the settling of solid particles in the liquid, which is inconvenient and affects work efficiency. A new type of sprayer is provided.
[0006] The purpose of this technical solution is achieved as follows:
[0007] A sprayer includes a housing having a liquid storage chamber, and further includes a rocker arm hinged to the housing.
[0008] A water absorption device is provided in the housing. The water absorption device includes a mounting sleeve installed in the liquid storage chamber, a piston core that moves within the mounting sleeve, and a drive rod provided in the piston core. A valve core mechanism is provided between the mounting sleeve and the piston core. The piston core cooperates with the valve core mechanism through piston movement to realize the suction and delivery of the solution in the liquid storage chamber.
[0009] A stirrer is fixed to the piston core. The side wall of the mounting sleeve is provided with a clearance groove for the stirrer to pass through. The length direction of the clearance groove is set in the direction of piston movement of the piston core. The rocker arm presses against the drive rod, and the drive rod drives the piston core to move, so that the piston core drives the stirrer to move in the liquid storage chamber.
[0010] With the above technical solution, when a sprayer is in normal use, the piston core is in its initial position. The operator presses down the rocker arm hinged to the housing. The rear end of the rocker arm acts on the drive rod, which in turn drives the piston core connected to it to slide downward within the mounting sleeve. Since the agitator is fixedly connected to the piston core through a relief groove, the relief groove provides directional movement space for the agitator, allowing the agitator to move downward synchronously. After the rocker arm is lifted, the valve core mechanism controls the piston core to retract to its initial position, thereby driving the agitator to move upward synchronously. By continuously lifting or pressing down the rocker arm, the agitator can continuously perform stirring by oscillating up and down within the liquid storage chamber. The single operation of the rocker arm synchronously drives the spraying and stirring actions, resulting in good coordination. The valve core mechanism enables the piston core to automatically reset, forming continuous reciprocating stirring, reducing liquid sedimentation, and improving work efficiency.
[0011] Preferably, the stirrer includes a connecting body connected to the piston core and at least one stirring blade disposed on the connecting body. The connecting body has a connecting groove, and the piston core has a corresponding connecting part. The connecting part is fitted with the connecting groove. The connecting part has grooves on both opposite sides along the fitting direction. The opposite inner sidewalls of the connecting grooves have corresponding protruding blocks for embedding into the grooves.
[0012] Through the above technical solution, the connecting groove of the connecting body in the stirrer is aligned with the connecting part of the piston core for fitting. At this time, the inserts on both sides of the connecting groove can also be embedded into the two grooves. The fitting method can be through deformation hard extrusion or sliding insertion. The inserts on both sides and the grooves on both sides are interlocked in both directions to form a rigid fitting. When the piston core slides up and down, the interlocking action of the inserts and grooves forces the stirrer to move synchronously and vertically without relative displacement, which restricts the separation of the stirrer and the piston core, realizes the stable cooperation between the two, and improves the stirring stability.
[0013] Preferably, the connecting part has a locking groove, and the connecting body has a corresponding locking protrusion. One side wall of the locking protrusion is a slope, and the other side wall is a plane. The connecting part has a guide arc surface, and one end of the groove is through the piston core sliding direction. When the insert slides into the groove through the through end, the locking protrusion is guided into the locking groove by the slope along the guide arc surface. The plane and the inner side wall of the locking groove are relatively abutted and defined.
[0014] Through the above technical solution, the positions of the two side inserts are aligned with the through openings of the two slots. The inserts slide horizontally into the slots through the through end along the sliding direction of the piston core, achieving rapid fitting. Simultaneously, the locking protrusion of the connecting body is guided to slide along the guide arc surface of the connecting part through its inclined surface until it is completely embedded in the locking groove, thus completing the assembly and improving assembly efficiency. The planar sidewall of the locking protrusion and the corresponding inner sidewall of the locking groove abut against each other to form a vertical limit, restricting reverse pull-out and preventing two-way detachment and locking, further improving the connection stability under reciprocating motion.
[0015] Preferably, there are two stirring blades, each comprising blade one and blade two. Blade one is smaller than blade two, and blade two is positioned relative to blade one near the bottom of the liquid storage chamber.
[0016] With the above technical solution, the number of stirring blades is preferably two, and the two blades are blade one and blade two with different sizes. Since particles in the solution are prone to settle at the bottom, blade two with a larger blade size is required to perform large-scale strong disturbance on the bottom area of the cavity with high sedimentation risk. Blade one simultaneously performs local weak disturbance on the middle and upper layer of the drug solution. The dual-stage stirring blades form zoned adaptive stirring according to the sedimentation gradient of the drug solution, which reduces stirring energy consumption and improves uniformity.
[0017] Preferably, it also includes a sprayer, the input end of which is connected to the piston core via a hose, and the housing is provided with a liquid passage communicating with the output end of the sprayer. The liquid passage includes a liquid outlet for providing spray, a solution chamber disposed in the piston core, and a liquid inlet for providing solution. The liquid passage is also provided with a pressure regulating chamber, which is formed between the mounting sleeve and the piston core.
[0018] The piston core is provided with a flow control valve one at the end near the pressure chamber, and the mounting sleeve is provided with a flow control valve two. The piston core moves up and down within the mounting sleeve. When the flow control valve one and the flow control valve two are close to each other, the flow control valve one is in the open state and the flow control valve two is in the closed state. When the flow control valve one and the flow control valve two are far apart, the flow control valve one is in the closed state and the flow control valve two is in the open state.
[0019] Through the above technical solution, when the piston core moves vertically within the mounting sleeve, its end flow control valve one and the mounting sleeve flow control valve two undergo relative displacement. When the two flow control valves approach each other, the pressure regulating chamber is reduced, squeezing the solution located in the pressure regulating chamber. Flow control valve one gradually opens and flow control valve two gradually closes, allowing the solution to enter the solution chamber. This forces the solution in the solution chamber to be transported along the conduit to the sprayer and atomized and sprayed out from the outlet. When the two flow control valves move away from each other, flow control valve one gradually closes and flow control valve two gradually opens, expanding the pressure regulating chamber. The solution in the storage chamber is replenished to the pressure regulating chamber through the inlet. At the same time, the solution hydraulically pushes flow control valve one to drive the piston core to reset, improving the cycle stability.
[0020] Preferably, the installation sleeve is equipped with a flow limiting cylinder, which is correspondingly connected to the outside of the flow control valve. The flow limiting cylinder has the liquid inlet, and the flow limiting cylinder has a plurality of liquid inlet grooves circumferentially opened along the liquid inlet. The liquid inlet grooves are connected to the liquid storage chamber through the flow limiting cylinder.
[0021] Through the above technical solution, the solution in the storage chamber needs to enter the flow limiting cylinder through the liquid inlet groove on its periphery. The solution in the flow limiting cylinder is supplied to the flow control valve two, which shortens the liquid replenishment cycle, reduces the single-point flow rate, disperses the fluid to avoid liquid replenishment impacting the flow control valve two, so that the automatic reset effect is controllable, and realizes flow control and valve body protection.
[0022] Preferably, the housing is provided with a base, and the base has a recessed groove. The recessed groove includes a first groove and a second groove. The second groove is connected to the side wall of the first groove. The flow-limiting cylinder is embedded in the first groove. The cross-sectional area of the first groove is larger than the cross-sectional area of the flow-limiting cylinder, so that there is a gap between the flow-limiting cylinder and the inner wall of the first groove.
[0023] With the above technical solution, the flow restrictor is embedded in the first groove of the base, and its cross-sectional area is smaller than that of the first groove to form an annular space. The liquid inlet of the flow restrictor is close to the bottom of the second groove. The solution is introduced through the liquid inlet groove set on the periphery. The second groove is laterally connected to the annular space of the first groove. The solution is released through the lateral guidance of the second groove. The annular space buffers and absorbs hydraulic pulsation, suppresses the transmission of vibration to the base, and protects the structural integrity.
[0024] The key and beneficial technical effects of this technical solution compared to existing technologies are:
[0025] 1. This technical solution uses a single operation of a rocker arm to synchronously drive spraying and stirring in a dual-effect synergy. The valve core mechanism enables the piston core to automatically reset, driving the stirrer to continuously reciprocate. The stirrer uniformly stirs the solution in the storage chamber, effectively preventing the solution from settling and improving work efficiency.
[0026] 2. This technical solution uses a dual-stage stirring blade design. The large blade strongly disturbs the bottom area of the cavity with high sedimentation risk, while the small blade simultaneously and weakly stirs the middle and upper layers. This achieves zoned adaptive stirring according to the sedimentation gradient, which reduces energy consumption and improves the uniformity of the drug solution, thereby enhancing the anti-settling effect.

[0036] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.
[0037] Example:
[0038] See Figure 1A sprayer includes a housing 1 and a base 101. The base 101 is installed at the bottom of the housing 1. The housing 1 is provided with a rocker arm 3. The rear end of the rocker arm 3 is hinged to the base 101, and the front end is used for handheld use. Its hinge axis is set in the horizontal direction. The housing 1 is often provided with a shoulder strap for carrying on the back, ensuring that the position of the rocker arm 3 conforms to the range of motion of the human left arm when the housing 1 is carried on the back. It also includes a sprayer 25, which is used to spray the solution inside the housing 1 in the form of mist. The sprayer can be installed on the side of the housing 1 for storage through a snap-fit structure to reduce the space occupied.
[0039] See Figure 2 , Figure 3 and Figure 4 The housing 1 has a liquid storage chamber 2, which is arranged in relation to the internal space of the housing 1. In this embodiment, the material cover on the top of the housing 1 can be unscrewed to open the feeding port. The solution (such as a pesticide formulation containing solid particles) is poured into the liquid storage chamber 2 through the feeding port for storage. The housing 1 is provided with a spray channel connected to the output end of the sprayer 25. The spray channel includes a liquid outlet 15 for providing spray, a solution chamber 16 and a liquid inlet 17 for providing solution. The liquid inlet 17 is connected to the liquid storage chamber 2 and the liquid storage port is located at the output end of the sprayer 25.
[0040] It also includes a water absorption device 4, which includes a mounting sleeve 41, a piston core 42, and a drive rod 43. The mounting sleeve 41 is located inside the liquid storage chamber 2 and is mounted on the housing 1. The piston core 42 is installed inside the mounting sleeve 41 and is slidably connected to the mounting sleeve 41. The sliding direction is along the inside of the mounting sleeve 41. The piston core 42 has the aforementioned solution chamber 16. The input end of the sprayer 25 is connected to the piston core 42 through a hose, thereby realizing the connection between the solution chamber 16 and the outlet 15. The drive rod 43 is located outside the housing 1. One of its upper ends is bent and fixed to the upper end of the piston core 42, and the other lower end extends toward the rocker arm 3. The lower end of the drive rod 43 is bent and extends to the bottom of the rocker arm 3 and abuts against the rocker arm 3, so that the swing of the rocker arm 3 can press against the drive rod 43 to drive it to move.
[0041] The intake passage is also provided with a pressure regulating chamber 18, which is formed between the mounting sleeve 41 and the piston core 42, specifically located between the lower outer wall of the piston core 42 and the inner wall of the lower end of the mounting sleeve 41. The size of the space within the pressure regulating chamber 18 can be adjusted by the up-and-down sliding movement of the piston core 42. A valve core mechanism is provided between the mounting sleeve 41 and the piston core 42. The valve core mechanism includes a flow control valve 19 and a flow control valve 20. The flow control valve 19 is located at the lower end of the piston core 42 and is preferably a one-way valve, which is used to open or close the pressure regulating chamber. The passage between the 18 and the solution chamber 16; the second flow control valve 20 is installed at the lower end of the mounting sleeve 41. The second flow control valve 20 is preferably a one-way valve. There is a pressure regulating chamber 18 between it and the first flow control valve 19. It is used to open or close the passage between the pressure regulating chamber 18 and the liquid storage chamber 2. Its operating state is the opposite of that of the first flow control valve 19. The cooperation relationship between the single valve core mechanism and the pressure regulating chamber 18 is the prior art and will not be described in detail here. For details, please refer to application number 200420044179.2, which discloses a hand-cranked sprayer.
[0042] The mounting sleeve 41 is equipped with a flow-limiting cylinder 21, which is threadedly connected to the lower end of the mounting sleeve 41. It fits precisely on the outside of the position of the flow control valve 20. The lower end of the flow-limiting cylinder 21 has a liquid inlet 17. At the end of the flow-limiting cylinder 21 located at the liquid inlet 17, several liquid inlet grooves 22 are also circumferentially formed. Each liquid inlet groove 22 is connected to the flow-limiting cylinder 21 and the liquid storage chamber 2. Figure 8 As shown, a recessed groove 23 is provided on the base 101, which includes a first groove 231 and a second groove 232. The shape of the first groove 231 is adapted to the flow-limiting cylinder 21, and its cross-sectional area is larger than that of the flow-limiting cylinder 21. The depth of the second groove 232 is less than that of the first groove 231. One end of the second groove 232 is connected to the side wall of the first groove 231. In this embodiment, the bottom of the second groove 232 is shown as an inclined surface 12, which is inclined downward towards the first groove 231. When the mounting sleeve 41 is installed, the lower end of the flow-limiting cylinder 21 is embedded in the first groove 231. A gap is left between the flow-limiting cylinder 21 and the inner peripheral wall of the first groove 231 to ensure that the solution can flow in. The solution enters the flow-limiting cylinder 21 after passing through each liquid inlet groove 22.
[0043] See Figure 5 , Figure 6 and Figure 7It also includes a stirrer 5, which is located inside the liquid storage chamber 2. The stirrer 5 is connected to the piston core 42. The stirrer 5 includes a connecting body 51 and at least one stirring blade 52. In this embodiment, two stirring blades 52 are shown. The two stirring blades 52 include blade one 521 and blade two 522, which are distributed along the length of the connecting body 51. Blade two 522 is larger than blade one 521 and has a larger area. Blade two 522 is located below blade one 521 and is closer to the bottom of the liquid storage chamber 2. Blade one 521 and blade two 522 are integrally connected to the connecting body 51.
[0044] The connection between the stirrer 5 and the piston core 42 is specifically achieved through a connecting part 7 on the side wall of the piston core 42. The connecting part 7 has grooves 8 on opposite sides along the sliding direction of the piston core 42, with the lower ends of the grooves 8 on both sides being through-holes, thus leaving a through opening in the connecting groove 6. The connecting part 7 has a guide arc surface 14 located at the end of the connecting part 7 near the through opening of the groove 8, facing outwards and downwards along the arc surface. The connecting body 51 has a corresponding connecting groove 6, the shape and size of which are adapted to the connecting part 7. The groove opening has two protruding inserts 9 on the inner walls of the groove on both sides, and the two inserts 9 are set one-to-one with the two grooves 8; the connecting part 7 also has a locking groove 10, which is located at one end of the connecting part 7 near the guide arc surface 14. The connecting body 51 has a corresponding locking protrusion 11, which protrudes from the lower groove wall of the connecting groove 6. Its size and shape are adapted to the locking groove 10. One side wall of the locking protrusion 11 is a slope 12 and the other side wall is a plane 13. The slope 12 is located on the side of the locking protrusion 11 facing the connecting groove 6.
[0045] See Figure 4 The side wall of the mounting sleeve 41 is provided with a relief groove 24, which extends from the inside of the mounting sleeve 41 to the outside. The length direction of the relief groove 24 is set to correspond to the sliding direction of the piston core 42. The connecting body 51 of the stirrer 5 can be connected to the connecting part 7 through the relief groove 24.
[0046] Align the positions of the two inserts 9 with the through openings of the two slots 8, and insert the two inserts 9 into the two slots 8 along the first direction (upward). At the same time, the connecting part 7 is also inserted into the connecting groove 6. During the sliding and fitting process, the inclined surface 12 of the locking protrusion 11 faces the guide arc surface 14 and is guided along the guide arc surface 14 until the locking protrusion 11 is inserted into the locking groove 10. At this time, the plane 13 faces the inner wall of the locking groove 10, so that when sliding along the opposite second direction (downward), the plane 13 abuts against the inner wall of the locking groove 10, restricting the locking protrusion 11 from coming out, thereby realizing the fixed connection between the stirrer 5 and the piston core 42.
[0047] Piston core 42 moves between a first position and a second position. When piston core 42 is in the first position, manually pressing down rocker arm 3 causes the rear end of rocker arm 3 to press down drive rod 43. The upper end of drive rod 43 synchronously drives piston core 42 downward, causing flow control valve 19 to approach flow control valve 20, and the space of pressure regulating chamber 18 to shrink, increasing the water pressure inside. The greater pressure causes flow control valve 19 to open and flow control valve 20 to close. Flow control valve 19 is in the open state, and flow control valve 20 is in the closed state. Solution flows into solution chamber 16 through flow control valve 19. The solution in the solution chamber 16 is transported along the conduit to the outlet 15 of the sprayer 25 and then sprayed out. At this time, the piston core 42 moves to the second position. After manually lifting the rocker arm 3, the pressure on the drive rod 43 is released, and the solution enters the flow limiting cylinder 21 through several inlet grooves 22, forcing the flow control valve 20 to switch to the closed state. The solution enters the pressure regulating chamber 18 through the flow control valve 20, pushing the lower end of the piston core 42 in the opposite direction (upward). The piston core 42 moves back to the first position to reset, thereby realizing the automatic adjustment of the piston core 42 for the next spray.
[0048] As the piston core 42 moves between the first position and the second position, it can drive the stirrer 5 to move up and down accordingly, thereby realizing the stirring operation of blade 1 521 and blade 2 522 in the liquid storage chamber 2.
[0049] The specific work process of this plan is as follows:
[0050] This technical solution involves the operator pressing down on the rocker arm 3 hinged to the housing 1. The rear end of the rocker arm 3 acts on the drive rod 43, which in turn drives the piston core 42 connected to it to slide downward within the mounting sleeve 41. Since the agitator 5 is fixedly connected to the piston core 42, the agitator 5 moves downward synchronously. When the rocker arm 3 is lifted, the valve core mechanism controls the piston core 42 to retract to its initial position, thereby driving the agitator 5 to move upward synchronously. By continuously lifting or pressing down the rocker arm 3, the agitator 5 can continuously perform stirring by swinging up and down in the liquid storage chamber 2. The single operation of the rocker arm 3 synchronously drives the spraying and stirring actions, resulting in good coordination. The valve core mechanism enables the piston core 42 to automatically reset, forming continuous reciprocating stirring, effectively preventing the liquid from settling and improving work efficiency.
[0051] The foregoing has shown and described the basic principles, main features, and advantages of this technical solution. Those skilled in the art should understand that this technical solution is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this technical solution. Various changes and modifications can be made to this technical solution without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed technical solution. The scope of protection of this technical solution is defined by the appended claims and their equivalents.
