Description

Technical Field

[0001] This application relates to the field of agricultural equipment technology, and in particular to an electric sprayer. Background Technology

[0002] Spraying pesticides or nutrient solutions is necessary in both plant maintenance and agricultural weeding, thus requiring the use of sprayers. Sprayers are classified into two types based on their operating method: manual and electric. Electric sprayers primarily use a pump to pump water containing pesticides or nutrient solutions through pipes from the spray gun. The nozzle of the spray gun atomizes the liquid and sprays it onto the plants and crops.

[0003] However, existing sprayers lack a mixing function. Since both pesticides and nutrient solutions need to be diluted with water before use, traditional sprayers require shaking after dilution to ensure thorough mixing, which is inconvenient. Furthermore, shaking the sprayer for mixing can result in insufficient mixing. Summary of the Invention

[0004] To facilitate stirring of the solution in the sprayer and to ensure thorough mixing of the medicine, nutrient solution and water, this application provides an electric sprayer.

[0005] The electric sprayer provided in this application adopts the following technical solution:

[0006] An electric sprayer includes a liquid storage tank, a base, a water pump, a stirring mechanism, and a transmission mechanism. The liquid storage tank is connected to the base and has a liquid storage chamber for storing a solution. The water pump is connected to the base and is used to draw the solution from the liquid storage chamber. The stirring mechanism includes a vertical rod and stirring blades. The vertical rod is rotatably connected to the liquid storage tank, and stirring blades are provided on the outer periphery of the vertical rod. The stirring blades are located inside the liquid storage chamber, and one end of the vertical rod extends out of the liquid storage chamber. The transmission mechanism connects the vertical rod and the water pump.

[0007] By adopting the above technical solution, the solution is stored in the storage chamber, and the transmission mechanism is connected between the stirring mechanism and the water pump. The water pump drives the stirring mechanism to rotate, thereby stirring the solution in the storage chamber and making the medicine and nutrient solution fully dissolve in the water.

[0008] Preferably, the transmission mechanism includes a driving bevel gear, an intermediate shaft, a driven bevel gear, a driving gear, and a driven gear. The driving bevel gear is connected to the water pump. The intermediate shaft is rotatably connected to the base. The axis of the intermediate shaft is parallel to the axis of the vertical rod. The driven bevel gear is coaxially connected to the intermediate shaft and is used to mesh with the driving bevel gear. The driving gear is coaxially connected to the intermediate shaft. The driven gear is coaxially connected to the vertical rod and is used to mesh with the driving gear.

[0009] By adopting the above technical solution, when the water pump is running, the water pump directly drives the active bevel gear to rotate, thereby driving the intermediate shaft, driven bevel gear, active gear and driven gear to rotate, realizing the conversion of the horizontal rotation of the water pump into the vertical rotation of the vertical rod. Through gear transmission, the transmission is smooth.

[0010] Preferably, the driving gear is axially slidably connected to the intermediate shaft, and the driving gear and the intermediate shaft are circumferentially fixed. The transmission mechanism also includes an abutment plate, which is slidably connected to the base. The sliding direction of the abutment plate is parallel to the sliding direction of the driving gear. The abutment plate is located between the driving gear and the driven bevel gear, and the side surface of the abutment plate away from the driven bevel gear abuts against the driving gear.

[0011] By adopting the above technical solution, the abutment plate is pushed up and down to slide, which drives the drive gear to slide. The drive gear is controlled to mesh with the driven gear. When the drive gear does not mesh with the driven gear, the water pump cannot drive the stirring mechanism to rotate. This avoids the solution impacting the stirring blades when adding solution to the storage tank, which would not drive the water pump to rotate and cause damage to the water pump.

[0012] Preferably, each tooth of the driving gear has a guide slope on both sides. The guide slope is located on the side of the driving gear closer to the driven gear. The distance between two guide slopes on the same tooth increases as the point moves away from the driven gear. The guide slope is used for sliding contact of the driven gear. Each tooth of the driven gear has a guide slope on both sides. The guide slope is located on the side of the driven gear closer to the driving gear. The distance between two guide slopes on the same tooth increases as the point moves away from the driving gear. The guide slope is used for sliding contact of the driving gear.

[0013] By adopting the above technical solution, a guide slope one is provided on the side of the driving gear facing the driven gear. The guide slope one is used for the driven gear to slide and abut. A guide slope two is provided on the side of the driven gear facing the driving gear. The guide slope two is used for the driving gear to slide and abut. When the teeth of the driving gear are not aligned with the tooth grooves of the driven gear, the driving gear can mesh with the driven gear through the guide slope one and the guide slope two during the sliding process.

[0014] Preferably, it also includes a spray gun; the spray gun is connected to the liquid storage tank, the vertical rod is vertical, the transmission mechanism also includes a sliding seat and a reset member, the sliding seat is slidably connected to the liquid storage tank, the sliding direction of the sliding seat is parallel to the length direction of the vertical rod, the sliding seat is used for placing the spray gun, the sliding seat is used to drive the abutment plate to slide, the reset member is connected between the abutment plate and the base, the reset member causes the abutment plate to have an upward sliding tendency.

[0015] By adopting the above technical solution, when the spray gun is placed on the sliding seat, the sliding seat moves down under the action of gravity, causing the abutment plate to move down against the elastic force of the reset component, thereby causing the drive gear to move down under its own gravity and disengage from the driven gear. When the spray gun is removed, the abutment plate moves up under the elastic force of the reset component, driving the drive gear to move up and engage with the driven gear, so that the water pump can drive the stirring mechanism to operate.

[0016] Preferably, the sliding seat is fixedly connected to the abutment plate.

[0017] By adopting the above technical solution, the sliding seat and the abutment plate are integrated, making the sliding of the abutment plate more stable.

[0018] Preferably, the liquid storage tank includes a main body, a lid, and a stop block. The main body is connected to a base and has the liquid storage cavity. The main body has a liquid inlet on the side away from the base, which connects the liquid storage cavity to the outside. The lid is connected to the main body and covers the liquid inlet. The sliding seat is slidably connected to the main body, and the stop block is slidably connected to the main body. The stop block is used to abut against the lid. One end of the stop block has a guide slope three, which is located on the side of the stop block facing the sliding seat. The distance from any point on the guide slope three to the other end of the stop block increases as the point moves away from the sliding seat. The guide slope three is used for the sliding seat to slide and abut against the stop block.

[0019] By adopting the above technical solution, the abutment block is slidably connected to the main body and is used to abut the bucket lid. When the abutment block abuts the bucket lid, the bucket lid cannot detach from the main body, thus locking the bucket lid. A guide slope three is provided at the end of the abutment block away from the bucket lid, which is used for the sliding seat to abut. When the spray gun is not placed on the sliding seat, the sliding seat moves upward, abutting against the guide slope three, causing the abutment block to move closer to the bucket lid. This prevents the bucket lid from being opened and water from being added to the storage chamber when the spray gun is not placed on the sliding seat, which would cause the stirring mechanism to rotate. In this case, the driving gear and driven gear would mesh, potentially damaging the water pump.

[0020] Preferably, the liquid storage tank further includes a second reset member, which is connected between the abutment block and the main body, and the second reset member causes the abutment block to tend to move away from the lid.

[0021] By adopting the above technical solution, the reset component two makes the abutment block tend to move away from the bucket lid. When the spray gun is placed on the sliding seat, the sliding seat moves down, and the abutment block moves away from the bucket lid under the action of the reset component two, making it easier to remove the bucket lid and then add solution into the liquid storage chamber.

[0022] Preferably, the bucket lid includes a lid body and a handle. The lid body is connected to the main body and covers the liquid inlet. The handle is provided on the side of the lid body away from the main body. The abutment block is provided with a limiting groove at the end near the bucket lid. The limiting groove is used for the handle to be inserted.

[0023] By adopting the above technical solution, a handle is provided on the side of the lid away from the main body, making it easy to open or close the lid. The abutment block is provided with a limiting groove for the handle to be inserted. When the handle is inserted into the limiting groove, the lid cannot rotate relative to the main body, thus locking the lid.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The solution is stored in the storage chamber. The transmission mechanism is connected between the stirring mechanism and the water pump. The water pump drives the stirring mechanism to rotate, thereby stirring the solution in the storage chamber and ensuring that the medicine and nutrient solution are fully dissolved in the water.

[0026] 2. When the spray gun is placed on the sliding seat, the sliding seat moves down due to gravity, causing the abutment plate to move down against the elastic force of the reset part 1. This causes the drive gear to move down under its own gravity and disengage from the driven gear. When the spray gun is removed, the abutment plate moves up due to the elastic force of the reset part 1, driving the drive gear to move up and engage with the driven gear, so that the water pump can drive the stirring mechanism to operate.

[0027] 3. The abutment block is slidably connected to the main body and is used to abut the bucket lid. When the abutment block abuts the bucket lid, the bucket lid cannot detach from the main body, thus locking the bucket lid. The end of the abutment block furthest from the bucket lid has a guide ramp three, which is used for the sliding seat to abut. When the spray gun is not placed on the sliding seat, the sliding seat moves upward, abutting against the guide ramp three, causing the abutment block to move closer to the bucket lid. This prevents the bucket lid from being opened and water from being added to the storage chamber when the spray gun is not placed on the sliding seat, which would cause the stirring mechanism to rotate. In this case, the driving gear and driven gear would mesh, potentially damaging the water pump. Attached Figure Description

[0060] The implementation principle of an electric sprayer according to an embodiment of this application is as follows: the spray gun 6 is embedded in the slot 5611. Under the action of gravity, the sliding seat 57 moves down, so that the abutment plate 56 moves down against the elastic force of the reset member 1 58. Then, the driving gear 54 moves down under its own gravity and disengages from the driven gear 55. The abutment block 13 moves away from the bucket cover 12 under the elastic force of the reset member 2 14, so as to facilitate the removal of the bucket cover 12 and the addition of solution to the liquid storage chamber 111. When the spray gun 6 is removed from the slot 5611, under the elastic force of the reset member 58, the abutment plate 56 moves upward, driving the drive gear 54 to move upward and mesh with the driven gear 55, so that the running water pump 3 can drive the stirring mechanism 4 to run. The abutment plate 56 drives the sliding seat 57 to move upward and abut against the guide inclined surface 131, so that the abutment block 13 overcomes the elastic force of the reset member 14 and slides towards the bucket lid 12. The side surface of the abutment block 13 facing the main body 11 abuts against the side surface of the bucket lid 12 away from the main body 11, and the handle 122 is embedded in the limiting groove 132 to lock the bucket lid 12.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
