[0033] The technical scheme in the utility model embodiment will be described clearly and completely in conjunction with the drawings in the utility model embodiment, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment.

[0034] Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of protection of the utility model.

[0035] Please refer to Figures 1-4The utility model provides a technical scheme:

[0036] A pesticide dropper with quantitative effect, comprising a delivery pipe 1, the front surface of the delivery pipe 1 is connected with a control block 2, the back surface of the delivery pipe 1 is connected with a pump, the front surface of the control block 2 is connected with a delivery pipe 3, a trigger cavity 5 is arranged in the control block 2, a film 51 is arranged in the trigger cavity 5, the bottom surface of the film 51 is connected with a bolt 52, a sliding rod 53 is slidably connected in the trigger cavity 5, a sliding groove 54 is formed in the sliding rod 53, and a sliding block 55 is slidably connected in the sliding groove 54.

[0037] A trachea 31 is arranged in the delivery pipe 3, one end of the trachea 31 is provided with an air hole 32, the air hole 32 is communicated with the side surface of the delivery pipe 3, the other end of the trachea 31 is communicated with the control block 2 and the trigger cavity 5 at the same time, the communication part of the trachea 31 and the trigger cavity 5 is located above the film 51, the bottom surface of the trigger cavity 5 is provided with a port for the lower end of the bolt 52 to pass through, a switch 7 is arranged below the port, the switch 7 is electrically connected with the pump, and the top and bottom surfaces of the sliding groove 54 present a trend from low to high from inside to outside.

[0038] When the pump is not started, the whole dropper is in a static state.

[0039] The spring 4 supports the sliding rod 53 upwards, the bolt 52 is inserted into the sliding groove 54 of the sliding rod 53, and the sliding block 55 remains stable in the sliding groove 54.

[0040] At this time, the pressure in the trigger cavity 5 is balanced with the outside, and the film 51 is in a natural state.

[0041] After the pump is started, the pesticide flows into the control block 2 from the delivery pipe 1 and passes through quickly.

[0042] Due to the fact that the delivery pipe 3 is located at the top end of the container and the side surface is in contact with air, according to the narrow tube effect, a negative pressure is formed in the control block 2.

[0043] The negative pressure makes the outside air enter the control block 2 from the air hole 32 in the side surface of the delivery pipe 3 through the trachea 31 to balance the pressure, and the pesticide continuously flows out of the delivery pipe 3.

[0044] With the continuous flow of the pesticide, when the pesticide liquid level in the container rises to the top end and the side surface of the delivery pipe 3 is closed, the trachea 31 cannot inhale air from the outside.

[0045] At this time, the negative pressure in the control block 2 cannot be supplemented, so that a negative pressure is generated in the trigger cavity 5.

[0046] Under the action of the negative pressure, the film 51 moves upwards and drives the bolt 52 to be pulled out of the sliding groove 54 of the sliding rod 53.

[0047] Without the support of the latch 52, the slider 55 retracts in the slider 53, and the slider 53 slides downward under its own weight, eventually triggering the switch 7 below.

[0048] Switch 7 is electrically connected to the pump. When triggered, the pump stops working, thus achieving the purpose of quantitatively dispensing insecticide.

[0049] With its unique air pressure control and mechanical triggering structure, it can precisely control the amount of insecticide dispensed each time, avoiding waste and environmental pollution caused by overuse, and preventing the insecticidal effect from being affected by insufficient dosage. It eliminates the need for constant monitoring and manual operation to control the dosage, reducing human intervention and making it more convenient to use.

[0050] Once the dispenser is installed in the appropriate position, the quantitative dispensing process can be completed automatically after the pump is turned on.

[0051] The entire dripper has a relatively simple structure, mainly consisting of an infusion tube 1, a control block 2, an outlet tube 3, a trigger chamber 5, and related connecting parts.

[0052] Fewer parts reduce the probability of failure, improve the stability and reliability of the equipment, and also facilitate later maintenance and repair.

[0053] Furthermore, a spring 4 is provided between the bottom surface of the slide rod 53 and the trigger chamber 5. The switch 7 is a timer switch 7. In the initial state, the pump is turned on. The control block 2 has an opening and closing chamber 21 and a connecting chamber 23. A sealing plug 22 is provided at the connection between the opening and closing chamber 21 and the connecting chamber 23. An extension rod is provided on the bottom surface of the sealing plug 22, which extends out of the connecting chamber 23. A connecting rod 6 is attached to the other end of the slide rod 53 and the extension rod.

[0054] The control block 2 is provided with a docking chamber 24, which is connected to the connecting chamber 23. A sealing plug 25 is provided at the connection between the connecting chamber 23 and the docking chamber 24. A spring 4 is connected to the top surface of the sealing plug 22 and the front surface of the sealing plug 25. An air passage 26 is provided in the control block 2. One end of the air passage 26 is connected to the air pipe 31, and the other end is connected to the docking chamber 24.

[0055] The top surface of the docking chamber 24 is connected to a connecting pipe 27, and the two ends of the connecting pipe 27 are connected to the air passage 26 and the trigger chamber 5, respectively.

[0056] When the pump is turned on, the insecticide flows from the infusion tube 1 into the control block 2. At this time, the pin 52 is firmly inserted into the slide rod 53, and supported by the spring 4, the slide rod 53 remains in a fixed position and cannot descend.

[0057] The sealing plug 22 tightly blocks the connection between the opening and closing chamber 21 and the connecting chamber 23, and the sealing plug 25 also tightly seals the interface between the connecting chamber 23 and the docking chamber 24, so that the whole device is in standby mode.

[0058] The preparation stage is started, the staff pushes the end of the connecting rod 6 to make it rise.

[0059] Because the slide rod 53, the extension rod and the connecting rod 6 constitute a simple lever structure with the slide rod 53 as the fulcrum, the action of the connecting rod 6 rising is transmitted to the extension rod through the principle of lever, driving the extension rod to rise.

[0060] The rising movement of the extension rod further pulls the sealing plug 22 to move upward, so that the opening and closing chamber 21 and the connecting chamber 23 are in communication with each other.

[0061] At the same time, the rising of the extension rod also promotes the rising of the blocking plug 25 through mechanical transmission, and the channel between the connecting chamber 23 and the docking chamber 24 is opened.

[0062] At this time, the insecticide can smoothly pass through the control block 2 and flow out from the agent outlet pipe 3, and the drip irrigation operation begins.

[0063] The quantitative execution stage, as the insecticide continues to flow out, when the insecticide in the container reaches the full state, the side of the agent outlet pipe 3 is completely closed.

[0064] According to the principle of narrow tube effect, the trachea 31 cannot inhale air from the outside, which leads to the generation of negative pressure in the trigger cavity 5.

[0065] Under the action of negative pressure, the film 51 moves upward, driving the bolt 52 to disengage from the slide rod 53. The slide rod 53 loses the support of the bolt 52 and rapidly descends under the action of gravity, triggering the switch 7, at which time the pump is closed.

[0066] The descent of the slide rod 53 destroys the original simple lever structure, the extension rod descends due to the disappearance of the lever effect, and the blocking plug 25 descends, resealing the channel between the connecting chamber 23 and the docking chamber 24.

[0067] At the same time, the sealing plug 22 also descends, cutting off the communication between the opening and closing chamber 21 and the connecting chamber 23, completely blocking the flow of insecticide, and automatically completing the quantitative drip irrigation operation.

[0068] After the staff releases his hand, the slide rod 53 rises upward again under the strong elastic force of the spring 4.

[0069] During the rising process, the bolt 52 reinserts into the corresponding position of the slide rod 53, the switch 7 is closed again after a delay, the pump is started, and the sealing plug 22 and the blocking plug 25 also return to the initial closed position under the action of the respective springs 4, tightly sealing the communication between the opening and closing chamber 21 and the connecting chamber 23, and the connecting chamber 23 and the docking chamber 24, respectively.

[0070] At this time, the device completes the overall reset and is ready for the next use at any time.

[0071] The entire device operation process only needs the staff to simply push one end of the connecting rod 6 to make it rise, which can start the device to work.

[0072] After completing the quantitative drip irrigation task, just release your hand, and the device can automatically complete the reset operation.

[0073] This simple and clear operation method greatly reduces the requirement for the professional skills of the operator, even ordinary users can easily get started and operate skillfully, significantly improving the ease of use of the device.

[0074] From the start of the device to drip pesticides, to automatically complete the quantitative and stop drip irrigation when the container is full, to the subsequent automatic reset, the entire process does not require continuous human intervention.

[0075] The entire work process is highly automated, greatly improving work efficiency, reducing labor input, and reducing labor costs, especially suitable for large-scale or frequent use of pesticides.

[0076] The device mainly uses simple levers, springs 4 and other common and mature mechanical structures, combined with air pressure triggering principles, to make each component work together and cooperate tacitly.

[0077] These structure designs are simple and reasonable, with relatively fewer parts, effectively reducing the probability of failure and greatly improving the stability and reliability of the device.

[0078] At the same time, the simple structure also makes the maintenance and repair of the device more convenient, reducing maintenance costs.

[0079] After each use, the device can accurately complete the reset operation, ensuring that the initial working state of the next use is exactly the same as the last time.

[0080] This excellent repeatability ensures that the accuracy and stability of quantitative drip irrigation remain the same during multiple uses, providing a strong guarantee for long-term and stable use of pesticides.

[0081] The back of the control block 2 is provided with a handle 61 adapted to the connecting rod 6, and the bottom surface of the connecting rod 6 and the top surface of the handle 61 are provided with anti-slip patterns 62.

[0082] A sealing ring is arranged in the connecting chamber 23, which has multiple layers and is arranged in a linear array, and the extension rod passes out from the center of the sealing ring.

[0083] The back of the control block 2 is specially provided with a handle 61 adapted to the connecting rod 6, which provides a comfortable and stable holding point for the staff.

[0084] When operating the dripper, the staff can more easily apply force to the connecting rod 6, greatly reducing the difficulty of operation.

[0085] Whether it is long continuous operation, or in complex environment work, the handle 61 can make the staff maintain a good operating posture, reduce hand fatigue, significantly improve the convenience of operation.

[0086] The anti-skid lines 62 on the bottom surface of the connecting rod 6 and the top surface of the handle 61 further optimize the operation experience.

[0087] These lines increase the friction between the two, so that the staff will not easily appear sliding phenomenon between the hand and the connecting rod 6 and the handle 61 when pushing the connecting rod 6 up or controlling its reset.

[0088] This not only improves the accuracy of operation, ensures that the staff can push the connecting rod 6 according to the expected force and direction, but also effectively avoids the operation error caused by hand slip, and protects the stable operation of the dropper.

[0089] The multiple layers of sealing rings arranged in linear array in the connecting chamber 23 provide excellent sealing performance for the dropper.

[0090] The extension rod passes out from the center of the sealing ring, and during the up and down movement of the extension rod, the multiple layers of sealing rings closely fit the surface of the extension rod, forming multiple layers of sealing defense lines.

[0091] This can effectively prevent the leakage of insecticide in the connecting chamber 23, ensure the insecticide to flow according to the predetermined path, and improve the reliability and safety of the dropper work.

[0092] Good sealing performance helps to prolong the service life of the dropper.

[0093] Preventing insecticide leakage can avoid its corrosion and damage to other precision components inside the control block 2, and reduce equipment failure caused by leakage.

[0094] This means that the dropper can maintain stable performance during long-term use, reduce the frequency of maintenance and replacement of equipment, and save costs for users.
