Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of agricultural machinery, and more specifically, to a spray generating device handle. In addition, the present invention also relates to a spray generating device comprising the spray generating device handle. Background Art
[0002] Sprayers play an important role in agricultural production. They can turn medicine or other liquids into mist and spray them evenly onto other objects to prevent and control pests and diseases.
[0003] The sprayer in the prior art usually includes a liquid storage tank, a nozzle, and a water pump and a motor arranged in the liquid storage tank. A handle is provided at the end of the nozzle for controlling the on and off of the water path of the nozzle. When the handle wrench is pressed, the water path of the nozzle is connected, and when the wrench is released, the water path of the nozzle is closed. The sprayer also includes a switch for controlling the on and off of the water pump motor. When the switch is pressed, the water pump motor is powered on, and when the switch is disconnected, the water pump motor is powered off.
[0004] However, since the handle wrench and the switch in the prior art independently control the on-off of the nozzle water path and the on-off of the motor, when in use, the user usually turns on the switch first to power on and start the water pump motor of the sprayer, and then presses the handle wrench to open the nozzle water path. This means that when the nozzle water path is not yet opened, the motor has already driven the water pump to press the water in the liquid storage tank into the nozzle, causing the water flow to rush up.
[0005] In summary, how to provide a sprayer handle that can prevent water flow from rushing up is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

DETAILED DESCRIPTION
[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0034] The core of the present invention is to provide a spray generating device handle, which can prevent the water flow from rushing up. Another core of the present invention is to provide a spray generating device including the spray generating device handle, which can prevent the water flow from rushing up.
[0035] Please refer to Figure 1-Figure 5 , Figure 1 A cross-sectional view of a specific embodiment of the handle of the spray generating device provided by the present invention when the wrench is not pressed; Figure 2 for Figure 1 The schematic diagram of the internal structure of the spray generating device when the handle wrench is pressed; Figure 3 for Figure 1 The structural diagram of the middle wrench; Figure 4 for Figure 1 Structural diagram of the mid-stroke amplifier; Figure 5 for Figure 1 Schematic diagram of the structure of the locking button.
[0036] The present invention provides a handle for a spray generating device, comprising a handle body 1 and a wrench 2, wherein the wrench 2 is rotatably connected to the handle body 1. A handle water channel 11 and a valve core 12 for controlling the opening and closing of the handle water channel 11 are provided in the handle body 1. It is understandable that a valve core slideway for setting the valve core 12 is also provided in the handle body 1, the valve core slideway is connected to the handle water channel 11, and the valve core 12 is provided with a blocking portion. When not in use, the blocking portion is located at the connection between the valve core slideway and the handle water channel 11, the valve core 12 is in a closed state, and the handle water channel 11 is closed; when the valve core 12 moves in the valve core slideway, the blocking portion clears the connection between the valve core slideway and the handle water channel 11, the valve core 12 opens, and the handle water channel 11 is connected.
[0037] A micro switch 13 for controlling the power on and off of the water pump motor of the spray generating device is also provided in the handle body 1. That is to say, the present invention arranges the micro switch 13 for controlling the power on and off of the water pump motor of the spray generating device in the handle body 1. When the micro switch 13 is turned on, the water pump motor is powered on and started, and when the micro switch 13 is turned off, the water pump motor is powered off.
[0038] It should be noted that the opening and closing of the micro switch 13 refer to two state signals of the micro switch 13 controlling the power on and off of the water pump motor, and do not refer to the action of the micro switch 13. It can be understood that when the action reed of the micro switch 13 is actuated, so that the moving contact at the end of the action reed is connected with the fixed contact, the micro switch 13 is turned on; when the action reed of the micro switch 13 is actuated, so that the moving contact at the end is disconnected from the fixed contact, the micro switch 13 is turned off.
[0039] The present invention adopts a wrench 2 to drive the valve core 12 and the micro switch 13 to operate. When the wrench 2 is pressed, the wrench 2 can sequentially drive the valve core 12 and the micro switch 13 to open, so that the water pump motor is powered on and started after the water path is connected. When the wrench 2 is released, the micro switch 13 and the valve core 12 are closed successively.
[0040] That is to say, the actions of the valve core 12 and the micro switch 13 in the present invention have a sequence, in other words, the opening and closing of the handle water channel 11 and the opening and closing of the water pump motor of the spray generating device have a sequence, so as to ensure that the handle water channel 11 is turned on before the water pump motor of the spray generating device is powered on, and is closed after the water pump motor is powered off, so as to prevent the water flow from rushing up.
[0041] Specifically, the handle body 1 is provided with a wrench shaft. When the wrench 2 is pressed, the wrench 2 can rotate around the wrench shaft. When the wrench 2 is released, the wrench 2 rotates around the wrench shaft in the opposite direction.
[0042] It is understandable that when the wrench 2 rotates around the wrench shaft, the displacement amounts at different positions on the wrench 2 at different distances from the wrench shaft are different. Therefore, the valve core 12 and the action reed of the micro switch 13 can be respectively contacted or connected with different positions of the wrench 2, and the action sequence of the valve core 12 and the action reed can be controlled by the displacement amounts at different positions.
[0043] As a preferred embodiment, the wrench 2 is provided with a valve core triggering part for triggering the action of the valve core 12 and a micro switch triggering part for triggering the action of the micro switch 13, and the distance from the valve core triggering part to the wrench shaft is greater than the distance from the micro switch triggering part to the wrench shaft.
[0044] It can be understood that when the wrench 2 is pressed to rotate the wrench 2 toward the direction approaching the microswitch 13 and the valve core 12, the valve core triggering part triggers the valve core 12 first, and the microswitch triggering part triggers the microswitch 13 later, that is, when the wrench 2 is pressed, the triggering timing of the valve core 12 is earlier than the triggering timing of the microswitch 13; when the wrench 2 is released to rotate the wrench 2 away from the microswitch 13 and the valve core 12, the microswitch triggering part first drives the microswitch 13 to reset, and the valve core triggering part drives the valve core 12 to reset later, that is, when the wrench 2 is released, the timing of resetting the microswitch 13 is earlier than the timing of resetting the valve core 12.
[0045] In summary, the spray generating device handle provided by the present invention has a valve core 12 and a micro switch 13 in the handle body 1, and the opening and closing sequences of the valve core 12 and the micro switch 13 can be controlled by the wrench 2, so that the valve core 12 is opened before the micro switch 13, and the valve core 12 is closed after the micro switch 13 is closed. Therefore, when the spray generating device handle is applied to the spray generating device, the handle water channel 11 can be turned on before the water pump motor of the spray generating device is powered on, that is, the handle water channel 11 is turned on first, and the water pump motor is powered on and operated later, so that the liquid delivered to the spray generating device handle at the beginning of use can be sprayed out in time to avoid water rushing up. When the spray generating device is stopped, the water pump motor is first powered off and stopped, and then the handle water channel 11 is closed to avoid water rushing up and pressure holding when the work stops.
[0046] Taking into account the implementation method of opening and closing the valve core 12, on the basis of the above embodiment, the wrench 2 is provided with a valve core accommodating groove 21, one end of the valve core 12 is against the bottom of the valve core accommodating groove 21, and the other end is connected to the handle body 1 through the valve core spring 122.
[0047] Preferably, a valve core pressing plate 121 is provided in the handle body 1 , and one end of the valve core 12 away from the valve core accommodating groove 21 is connected to the valve core pressing plate 121 via a valve core spring 122 .
[0048] When the wrench 2 is pressed, the valve core accommodating groove 21 rotates with the wrench 2. Under the forced thrust of the valve core accommodating groove 21, the external force acting on the wrench 2 is applied to the end of the valve core 12 that is against the bottom of the valve core accommodating groove 21, thereby pushing the valve core 12 to move along the valve core slideway, so that the valve core 12 opens, and then the handle water channel 11 is opened.
[0049] It can be understood that when the valve core accommodating groove 21 pushes the valve core 12 to move, the valve core spring 122 located at the other end of the valve core 12 is compressed to generate an elastic restoring force. Therefore, when the wrench 2 is loosened, the external force acting on the wrench 2 is eliminated, and the valve core accommodating groove 21 no longer applies a pushing force to the valve core 12. At this time, under the action of the elastic restoring force of the valve core spring 122, the valve core 12 is pushed to slide in the opposite direction to reset, so as to block the connection between the valve core slide and the handle water channel 11, so that the valve core 12 is closed, thereby closing the handle water channel 11.
[0050] Taking the sealing performance into consideration, preferably, a first sealing ring is provided between the valve core 12 and the valve core slide at the end close to the valve core accommodating groove 21; a second sealing ring is provided between the end of the sealing portion of the valve core 12 away from the valve core accommodating groove 21 and the valve core slide; and a third sealing ring is provided between the valve core pressure plate 121 and the valve core slide.
[0051] Preferably, the first sealing ring is coated with grease to ensure that the valve core 12 moves smoothly during compression and rebound to avoid sticking, slow rebound and other phenomena.
[0052] Taking into account the implementation method of opening and closing the micro switch 13, based on any of the above embodiments, a transmission member is provided in the handle body 1 for transmitting the rotational power of the wrench 2 to the micro switch 13 to drive the micro switch 13 to operate.
[0053] That is to say, in this embodiment, the wrench 2 indirectly drives the micro switch 13 to operate through the transmission member. The transmission member serves as an intermediate connecting member and can transmit the power of the wrench 2 to the micro switch 13. Therefore, the setting of the micro switch 13 can be facilitated, so that the micro switch 13 has a more flexible position relative to the wrench 2.
[0054] In order to save the internal space of the handle body 1 , on the basis of the above embodiment, the transmission member is a stroke amplifier 3 for amplifying the rotation stroke of the wrench 2 .
[0055] That is to say, the transmission member in this embodiment is equivalent to a stroke amplifier, which amplifies the smaller stroke applied to the transmission member by the wrench 2, so that the transmission member has a larger output stroke, so that the micro switch 13 can be driven to operate when the wrench 2 is rotated by a smaller angle, thereby satisfying the requirement of opening the micro switch 13 in a very small space.
[0056] Preferably, the stroke amplifier 3 is rotatably connected to the handle body 1 via a transmission shaft.
[0057] That is to say, the stroke amplifier 3 in this embodiment is a rotating member, and the stroke amplifier 3 converts the smaller angular displacement applied by the wrench 2 into a larger output displacement through its own rotation, so as to drive the micro switch 13 to operate.
[0058] Taking into account the specific structure and mode of action of the stroke amplifier 3, on the basis of the above embodiment, the stroke amplifier 3 includes a first abutment portion for abutting against the wrench 2 and a second abutment portion for pushing the micro switch 13 to operate, and the distance from the first abutment portion to the transmission member shaft is smaller than the distance from the second abutment portion to the transmission member shaft.
[0059] Specifically, when the wrench 2 is pressed, the portion of the wrench 2 that contacts the first abutting portion applies the external force acting on the wrench 2 to the first abutting portion, so that the first abutting portion drives the transmission member to rotate around the transmission member shaft as the wrench 2 rotates. When the transmission member rotates to a certain position, the second abutting portion contacts the action reed of the microswitch 13, and pushes the action reed of the microswitch 13 to move as it rotates, so that the moving contact at the end of the action reed contacts the static contact of the microswitch 13, thereby opening the microswitch 13 and energizing the water pump motor of the spray generating device using the handle of the spray generating device.
[0060] When the wrench 2 is loosened, the transmission member rotates in the opposite direction. As the transmission member rotates, the second abutment portion disengages from the action reed of the microswitch 13, so that the moving contact at the end of the action reed is separated from the static contact of the microswitch 13, and the microswitch 13 is closed until the transmission member is reset to the initial position and the wrench 2 is reset to the unused state.
[0061] Taking into account the convenience of resetting the transmission member, on the basis of the above embodiment, a torsion spring for driving the stroke amplifier 3 to reset is sleeved on the transmission member shaft.
[0062] That is, when the wrench 2 is pressed, the torsion spring undergoes elastic deformation as the transmission member rotates; when the wrench 2 is released, the torsion spring recovers its elastic deformation, driving the transmission member to rotate in the opposite direction.
[0063] Taking into account the simplicity and feasibility of the specific structure of the transmission member, on the basis of the above embodiment, the transmission member includes a ring 31 that is sleeved with the transmission member shaft, a fan-shaped frame 32 with the ring 31 as the center, and a rocker arm 33 extending along the side of the fan-shaped frame 32 away from the wrench 2. The length of the rocker arm 33 is greater than the radius of the fan-shaped frame 32, the first abutment portion is located at the end of the fan-shaped frame 32 close to the wrench 2, and the second abutment portion is located at the free end of the rocker arm 33.
[0064] That is to say, the transmission member of this embodiment is generally a fan-shaped frame structure, which is simple and light. The distance from the first abutment portion to the transmission member rotation axis is the radius of the fan-shaped frame 32, and the distance from the second abutment portion to the transmission member rotation axis is the length of the swing rod 33. Since the length of the swing rod 33 is greater than the radius of the fan-shaped frame 32, the distance from the first abutment portion to the transmission member rotation axis is less than the distance from the second abutment portion to the transmission member rotation axis.
[0065] Considering the structural strength of the sector frame 32 , preferably, reinforcing ribs are provided inside the sector frame 32 along its radial direction to increase the bearing pressure of the sector frame 32 .
[0066] It should be noted that the present embodiment does not impose any specific limitation on the central angle of the sector frame 32. The larger the central angle, the smaller the angle at which the wrench 2 is rotated to drive the micro switch 13 to operate, and the smaller the central angle, the greater the angle at which the wrench needs to be rotated.
[0067] In order to ensure that the wrench 2 can reliably trigger the transmission member to rotate, based on the above embodiment, the wrench 2 is provided with: a ramp surface 22 for abutting against the first abutting portion, and a thrust surface 23 intersecting with the ramp surface 22 for preventing the first abutting portion and the ramp surface 22 from slipping.
[0068] It can be understood that the ramp surface 22 can ensure that the movement of the wrench 2 is more effectively transmitted to the first abutment portion; the thrust surface 23 can effectively stop the first abutment portion, causing the first abutment portion to rotate in the rotation direction of the wrench 2 to prevent the first abutment portion and the ramp surface 22 from slipping.
[0069] Considering that during use, the valve core 12 and the micro switch 13 need to be opened during the entire working process, therefore, it is necessary to ensure that the wrench 2 is always in a pressed state during work. For this reason, based on the above embodiment, the handle body 1 is provided with a locking button 14 for locking the wrench 2 when the valve core 12 and the micro switch 13 are both opened.
[0070] That is to say, in this embodiment, the locking button 14 is used to ensure that the wrench 2 is in a pressed state when being pressed.
[0071] Taking into account the simplicity of the structure and the ease of implementation of the locking button 14, on the basis of the above embodiment, the locking button 14 includes a pressing portion 141 and a locking portion 142, and the wrench 2 is provided with a stop portion 24 for cooperating with the locking portion 142 to lock when the pressing portion 141 is pressed, and the locking button 14 also includes a release spring for driving the pressing portion 141 to return to its original position when the stop portion 24 is unlocked from the locking portion 142.
[0072] Specifically, when locking is required, the wrench 2 is first pressed down completely so that the stopper 24 on the wrench 2 moves away from the locking portion 142 on the locking button 14, and then the pressing portion 141 is pressed down. At this time, the wrench 2 is released, and the wrench 2 has a tendency to reset under the action of the valve core spring 122 and the torsion spring. The wrench 2 rotates slightly in the reset direction. When the stopper 24 and the locking portion 142 are locked, the pressing portion 141 cannot pop out due to the action of the stopper 24, and under the action of the locking portion 142, the wrench 2 stays in the pressed working position.
[0073] When the use is completed and the spanner 2 needs to be loosened, the spanner 2 is pressed down completely again to make the stopper 24 move away from the locking portion 142. At this time, under the action of the release spring, the pressing portion 141 drives the locking button 14 to reset to prevent the locking portion 142 from interfering with the reset of the spanner 2. The spanner 2 is reset to the non-working position under the action of the valve core spring 122 and the torsion spring.
[0074] In this embodiment, the locking method of the locking portion 142 and the stop portion 24 is not limited. The locking portion 142 and the stop portion 24 can be inserted and locked, or they can be snap-fitted and locked.
[0075] In order to avoid accidental operation of pressing the wrench 2 when not in use, based on the above embodiment, the wrench 2 is provided with a lock hook 25, and the handle body 1 is provided with a lock hook hanging member 15 for hanging with the lock hook 25 to avoid pulling the wrench 2 when not in use.
[0076] That is to say, when not in use, the lock hook 25 is hung on the lock hook hanging member 15 so that the wrench 2 cannot be moved, thereby preventing the valve core 12 and the micro switch 13 from being opened due to misoperation of the wrench 2 .
[0077] When in use, the lock hook 25 is detached from the lock hook hanging member 15, and the wrench 2 can be pulled.
[0078] In addition to the above-mentioned spray generating device handle, the present invention also provides a spray generating device including the spray generating device handle disclosed in the above-mentioned embodiment. For the structures of other parts of the spray generating device, please refer to the prior art and will not be described in detail herein.
[0079] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
[0080] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0081] The above is a detailed introduction to the spray generating device handle and the spray generating device provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention.
