Description

Technical Field

[0001] This utility model relates to the field of atomizing device technology, specifically to a handheld blower fog cannon. Background Technology

[0002] In agriculture, manual spraying of pesticides on crops is usually required.

[0003] Chinese patent CN212488147U discloses a handheld air-assisted sprayer, which includes a hollow shell with a front end for the air duct and a rear end for the storage compartment. An air supply pipe is installed inside the air duct, and a nozzle assembly is located at the front end of the air supply pipe. A water tank and a battery are located inside the storage compartment. A push-button switch is located on the top of the storage compartment. The water tank has an inlet and an outlet. The inlet of the water tank extends out of the storage compartment and is sealed with a screw cap. The outlet of the water tank is connected to the nozzle assembly via a water supply pipe and a flow regulating valve. A fan is located near the rear end of the air supply pipe, blowing air towards the nozzle assembly. The fan, push-button switch, and battery are connected by wires to form a power supply circuit. It is convenient and flexible to use. However, during spraying, the operator needs to continuously swing the spray pipe to achieve large-area spraying. For low-lying crops, the spray pipe needs to be swung horizontally, while for taller fruit trees, it needs to be swung vertically, resulting in high manual labor intensity.

[0004] Based on this, this utility model designs a handheld blower fog cannon to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a handheld blower fog cannon.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A handheld fog cannon includes a sprayer body, a corrugated tube, and a spray pipe;

[0008] A corrugated pipe is fixedly installed between the air outlet end of the sprayer body and the air inlet end of the spray pipe, so that the corrugated pipe can extend, retract and bend.

[0009] A water inlet pipe is fixedly installed on the side wall of the air outlet end of the spray pipe. The water inlet end of the water inlet pipe is used to connect to the water supply structure inside the sprayer body. The water outlet end of the water inlet pipe extends to the inside of the spray pipe and is fixedly connected to the atomizing nozzle. The atomizing nozzle is coaxially arranged with the spray pipe. A flow regulating valve is installed on the water inlet pipe.

[0010] A self-rotating water mist breaking component is installed between the atomizing nozzle and the spray pipe to create a vortex at the air outlet, which completely breaks up the sprayed water mist and makes the spray finer.

[0011] An adjustable swing mechanism is provided on the outer wall of the air inlet end of the spray pipe to control the reciprocating swing of the spray pipe.

[0012] Furthermore, the self-rotating water mist breaking assembly includes a pressure cap, a stop block, and a cyclone fan blade. A stop block is fixedly installed on the outer ring surface of the atomizing nozzle, which is used to limit the cyclone fan blade. The cyclone fan blade is sleeved on the outside of the atomizing nozzle and can rotate freely around the atomizing nozzle. The pressure cap is detachably connected to the air outlet end of the spray pipe, and the pressure cap abuts against the cyclone fan blade. The pressure cap and the stop block cooperate to limit the cyclone fan blade on the atomizing nozzle. When the machine is running, the airflow flows to the outside of the spray pipe. When the airflow passes through the cyclone fan blade, it will drive the cyclone fan blade to rotate, thereby generating a cyclone at the air outlet end of the spray pipe, which completely breaks up the sprayed water mist and makes the spray finer.

[0013] Furthermore, the inner ring surface of the cap and the air outlet end of the spray pipe are provided with matching threads.

[0014] Furthermore, the adjustable swing mechanism includes a support frame, a rotating rod, and a drive assembly. The support frame is located on the outside of the air inlet end of the spray pipe, and rotating rods are symmetrically arranged on both sides of the spray pipe. One end of the rotating rod is fixedly connected to the spray pipe, and the other end of the rotating rod is rotatably connected to the support frame. The drive assembly is mounted on the support frame and is used to control the spray pipe to swing back and forth around the rotating rod.

[0015] Furthermore, handles are fixedly installed on the two side walls connected to the support frame.

[0016] Furthermore, the drive assembly includes a motor, a rotating disk, a connecting rod, rollers, a linkage plate, and an amplitude adjustment assembly. The motor is fixedly connected to the support frame, and the output end of the motor is fixedly connected to the rotating disk. An adjustment assembly is provided between the rotating disk and the connecting rod, which is used to control the connecting rod to slide radially along the rotating disk. A roller is rotatably mounted on one end of the connecting rod near the spray pipe. The linkage plate is fixedly connected to the outer wall of the spray pipe, and a slot is provided on the linkage plate for rolling connection with the roller.

[0017] Furthermore, the swing amplitude adjustment assembly includes a slider and a screw. A groove is provided on the rotating disk along the radial direction of the rotating disk, and the slider is limited and slidably placed in the groove. The screw is rotatably connected to the rotating disk, and the slider is threadedly connected to the screw through a threaded sleeve.

[0018] Furthermore, the support frame has symmetrical movable slots on both sides.

[0019] Compared with the prior art, the advantages of this utility model are as follows: the operator carries the sprayer body on his back and holds the spray pipe in his hand. The atomizing nozzle sprays atomized droplets, and the airflow enters the spray pipe from the sprayer body and blows outward, blowing out the atomized droplets to achieve the effect of air-driven spraying. When the airflow flows in the spray pipe, it drives the self-rotating water mist breaking component to operate, so that the airflow generates a vortex, which completely breaks up the sprayed water mist, making the spray finer, thereby effectively improving the atomization effect and increasing the uniformity of the spraying effect on the plants. At the same time, the operator can activate the adjustable swing mechanism to control the spray pipe to swing back and forth, increasing the spraying range of the liquid and effectively reducing the intensity of manual labor.

[0030] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A handheld blower fog cannon includes a sprayer body 1, a corrugated pipe 2, and a spray pipe 3;

[0031] The sprayer body 1 adopts mature technology in this field, which will not be described in detail in this article;

[0032] A corrugated pipe 2 is fixedly installed between the air outlet end of the sprayer body 1 and the air inlet end of the spray pipe 3, so that the corrugated pipe 2 can extend, retract and bend.

[0033] A water inlet pipe 7 is fixedly installed on the side wall of the air outlet end of the spray pipe 3. The water inlet end of the water inlet pipe 7 is used to connect to the water supply structure inside the sprayer body 1. The water outlet end of the water inlet pipe 7 extends to the inside of the spray pipe 3 and is fixedly connected to the atomizing nozzle 6. The atomizing nozzle 6 is coaxially arranged with the spray pipe 3. A flow regulating valve 8 is provided on the water inlet pipe 7.

[0034] A self-rotating water mist breaking component is provided between the atomizing nozzle 6 and the spray pipe 3 to generate a vortex at the air outlet, which completely breaks up the sprayed water mist and makes the spray finer.

[0035] An adjustable swing mechanism is provided on the outer wall of the air inlet end of the spray pipe 3 to control the reciprocating swing of the spray pipe 3.

[0036] In this invention, the operator carries the sprayer body 1 on their back and holds the spray pipe 3 in their hand. The atomizing nozzle 6 sprays atomized droplets. The airflow enters the spray pipe 3 from the sprayer body 1 and blows outward, blowing out the atomized droplets to achieve the effect of air-driven spraying. When the airflow flows in the spray pipe 3, it drives the self-rotating water mist breaking component to operate, creating a vortex at the outlet to completely break up the sprayed water mist, making the spray finer and thus effectively improving the atomization effect and increasing the uniformity of the spraying effect on the plants. At the same time, the operator can activate the adjustable swing mechanism to control the spray pipe 3 to swing back and forth, increasing the spraying range of the liquid and effectively reducing the intensity of manual labor.

[0037] The self-rotating water mist breaking assembly includes a pressure cap 9, a stop block 10, and a cyclone fan blade 11. The stop block 10 is fixedly installed on the outer ring surface of the atomizing nozzle 6. The stop block 10 is used to limit the cyclone fan blade 11. The cyclone fan blade 11 is sleeved on the outside of the atomizing nozzle 6 and can rotate freely around the atomizing nozzle 6. The pressure cap 9 is detachably connected to the air outlet end of the spray pipe 3, and the pressure cap 9 abuts against the cyclone fan blade 11. The pressure cap 9 and the stop block 10 cooperate to limit the cyclone fan blade 11 on the atomizing nozzle 6. When the machine is running, the airflow flows to the outside of the spray pipe 3. When the airflow passes through the cyclone fan blade 11, it will drive the cyclone fan blade 11 to rotate, thereby generating a cyclone at the air outlet end of the spray pipe 3, which completely breaks up the sprayed water mist and makes the spray finer.

[0038] Specifically, the inner ring surface of the pressure cap 9 and the air outlet end of the spray pipe 3 are provided with matching threads, which can facilitate the disassembly and assembly of the cyclone fan blade 11, making it convenient for machine inspection and maintenance.

[0039] The adjustable swing mechanism includes a support frame 4, a rotating rod 12, and a drive assembly. The support frame 4 is located on the outside of the air inlet end of the spray pipe 3. The rotating rods 12 are symmetrically arranged on both sides of the spray pipe 3. One end of the rotating rod 12 is fixedly connected to the spray pipe 3, and the other end of the rotating rod 12 is rotatably connected to the support frame 4. The drive assembly is installed on the support frame 4 and is used to control the spray pipe 3 to swing back and forth around the rotating rod 12.

[0040] The support frame 4 has symmetrical movable slots on both sides to avoid the spray pipe 3 when it swings.

[0041] Handles 5 are fixedly installed on the two side walls connected to the support frame 4. Each handle 5 has a switch. By holding different handles 5, the operator can switch the swing posture of the spray pipe 3 to meet the vertical reciprocating swing and horizontal reciprocating swing requirements of the spray pipe 3.

[0042] The drive assembly includes a motor 13, a rotating disk 14, a connecting rod 15, a roller 16, a linkage plate 17, and a swing adjustment assembly. The motor 13 is fixedly connected to the support frame 4, and the output end of the motor 13 is fixedly connected to the rotating disk 14. An adjustment assembly is provided between the rotating disk 14 and the connecting rod 15. The adjustment assembly is used to control the connecting rod 15 to slide radially along the rotating disk 14. A roller 16 is rotatably mounted on one end of the connecting rod 15 near the spray pipe 3. The linkage plate 17 is fixedly connected to the outer wall of the spray pipe 3, and a slot is provided on the linkage plate 17 for rolling connection with the roller 16.

[0043] The swing amplitude adjustment assembly includes a slider 18 and a screw 20. A groove 19 is provided on the rotating disk 14 radially, and the slider 18 is slidably limited in the groove 19. The screw 20 is rotatably connected to the rotating disk 14, and the slider 18 is threadedly connected to the screw 20 through a threaded sleeve.

[0044] In this invention, the motor 13 drives the rotating disk 14 to rotate, which in turn drives the connecting rod 15 to rotate. The roller 16 rolls in the slot of the linkage plate 17, causing the spray pipe 3 to swing back and forth around the rotating rod 12. By rotating the screw 20, the slider 18 can be controlled to slide in the slide groove 19 to adjust the eccentricity of the connecting rod 15. The greater the eccentricity of the connecting rod 15, the greater the swing amplitude of the spray pipe 3, which can adapt to different spraying needs.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
