Description

Technical Field

[0001] The present invention relates to the technical field of sanitation and epidemic prevention in public places, pest control and disinfection in livestock breeding sites, and agricultural and forestry pest control equipment, and specifically to an all-in-one spray powder spraying machine and a spray powder spraying method, in particular to an all-in-one ion spray powder spraying machine and a spray powder spraying method with a static elimination function. Background Art

[0002] Spraying and dusting are one of the effective methods for public health disinfection, pest control and disinfection in livestock breeding sites, and agricultural and forestry pest control.

[0003] Spraying is a process of breaking up liquid medicine through high-pressure and high-speed airflow, and finally forming tiny droplets and transporting them out. It has the advantages of small droplet size, long spray distance, long hovering time, and high diffusion degree.

[0004] Powder spraying uses airflow to atomize powder particles and spray them out, thereby killing pests and diseases. It is simple to operate and has good control effects.

[0005] However, most existing equipment is specialized, offering only a single spray or powdering function, making it unable to meet diverse operational needs. The fine powder used in powder spraying is prone to electrostatic agglomeration, resulting in poor or even no atomization, significantly impacting application effectiveness. The sprayed pesticide or powder can only be controlled chemically, typically effectively against diseases and insect pests, but with limited effectiveness against bacteria and microorganisms. It also lacks the ability to reduce PM2.5 levels, deodorize, or remove odors. Summary of the Invention

Ion generator 18 generates a large amount of ion charge through ion emitting terminal 11.

[0052] Among them, such as Figure 8 As shown, the powder spraying tube 5 includes a tube 5A and a rear end head 5B. The rear end head 5B is fixed to the outer wall of the rear end of the tube 5A by interference fit. The front end of the rear end head 5B is a cone that can be sealed with the conical part of the inner hole of the wind shield 6.

[0053] Among them, such as Figure 9 As shown, part of the outer wall of the liquid outlet pipe 14 is threaded, and the impeller fixing cover 15 is locked on the liquid outlet pipe 14 by a nut 22; Figure 1 and Figure 8 As shown, the end cover 7, the impeller 16 and the impeller fixing cover 15 are connected in sequence by screws 20. When the screws 20 are installed, the end cover 7 can be sealed by the sealing ring and tightly fixed to the front end of the housing 1.

[0054] like Figure 1 As shown in Figure 4, the outer shell 1 includes a wind tube side shell 1A and a handle side shell 1B that are connected to each other. The wind tube 12 is clamped in the interior of the wind tube side shell 1A. An opening is provided on the bottom side of the front part of the wind tube side shell 1A. The lower side of the wind tube 12 extends outward from the opening and is then threadedly connected to the medicine pot 8.

[0055] like Figure 2 or Figure 5 As shown, the ion generator 18 is located inside the handle side housing 1B, and the switch button 9 is set on the handle side housing 1B to control the start and stop of the whole machine.

The inlay nut is directly embedded in the inner front end of the air channel 21 during injection molding, and the internal thread of the inlay nut is connected to the external thread of the rear end of the liquid outlet pipe 14. Figure 10 As shown, the front end of the impeller 16 is provided with a plurality of front blades 16A, and the rear end is provided with a plurality of rear blades 16B. The rear end of the impeller through hole 16C in the middle of the impeller 16 is conical, and the front end is cylindrical. There is a gap between the impeller through hole 16C in the middle of the impeller 16 and the front end of the liquid outlet pipe 14.

[0058] The power source 2 is a quickly detachable battery pack, and the outer shell of the battery pack is connected to the bottom of the handle side shell 1B via screws 20 .

[0059] like Figure 1 - As shown in FIG3 , when used as an ion sprayer, one end of the liquid pipette 19 is inserted into the airway 21 and the outer wall of the liquid pipette 19 is sealed and plugged with the inner wall of the airway 21 through a sealing ring. Figure 4-Figure 7 As shown, when used as an ion powder sprayer, a windshield plug 6 is installed on the end cover 7, and the rear part of the inner hole of the windshield plug 6 is tapered. When the end cover 7 is engaged with the windshield plug 6, the rear end head 5B of the powder spraying tube 5 is limited between the windshield plug 6 and the front end of the impeller through hole 16C of the impeller 16. At the same time, the front end of the liquid outlet pipe 14 is inserted into the inner hole at the rear end of the powder spraying tube 5, and the front end outer wall of the liquid outlet pipe 14 is sealed and plugged with the inner hole wall at the rear end of the powder spraying tube 5 through a sealing ring. The engagement method between the end cover 7 and the windshield plug 6 adopts the existing technology, specifically: two card slots are provided on the end cover 7, and two card blocks are provided on the windshield plug 6. After the windshield plug 6 is covered on the end cover 7, the windshield plug 6 is rotated.

[0060] In this embodiment, the liquid suction pipe 19 or the wind shield 6 and the powder spraying pipe 5 are quickly replaced to achieve rapid switching of the powder spraying.

[0061] In this embodiment, the wind speed of the fan 10 and the start and stop functions of the equipment can be controlled through the control panel 4 and the switch button 9.

[0062] The battery pack of this embodiment adopts a quick-change and quick-plug design.

[0063] When working, the battery pack supplies power to the device, and the switch button 9 and the control panel 4 control the start, stop and gear position. Figure 1-Figure 3 As shown, first, remove the medicine pot 8 and insert the liquid suction tube 19 into the entrance of the air duct 21 on the lower side of the wind tube 12. The outer circle of the liquid suction tube 19 and the inner wall of the air duct 21 are sealed by at least one sealing ring. Screw on the medicine pot 8 and press the switch button 9. The fan 10 and the ion generator 18 are connected to the power supply 2 and both work simultaneously. The gear of the fan 10 can be adjusted through the control panel 4 according to the needs. The fan 10 generates airflow, see Figure 3Arrow, the ion emission end 11 generates a large amount of ion charge and moves with the airflow. Part of the airflow passes through the air inlet one-way valve 13 and enters the medicine pot 8, applying positive pressure to the liquid medicine in the medicine pot 8, and another part of the airflow passes through the front blades 16A of the impeller 16 to the periphery of the impeller through hole 16C in the middle of the impeller 16, and another part of the airflow passes through the rear blades 16B of the impeller 16 to the inside of the impeller through hole 16C in the middle of the impeller 16. Both parts of the airflow flow out from the end cover through hole 7A in the middle of the end cover 7 and form a negative pressure at the front end of the liquid outlet pipe 14. Under the action of positive and negative pressure differences, the liquid medicine in the medicine pot 8 passes through the suction pipe 19, the air duct 21 of the wind tube 12, and the liquid outlet pipe 14 in turn, and is atomized and sprayed to the target under the action of the airflow coming out of the impeller through hole 16C in the middle of the impeller 16 and the end cover through hole 7A in the middle of the end cover 7. A large number of ions in the airflow continue to neutralize the target and surrounding objects, killing bacteria they come into contact with. At the same time, the ions continuously absorb various microparticles in the air, such as dust and smoke, to achieve the functions of reducing PM2.5, deodorizing and removing odors.

[0064] When spraying powder, Figure 4-Figure 7 As shown, first clamp the windshield plug 6 onto the end cover 7, and the powder spraying tube 5 is inserted into the windshield plug 6. The tail end of the powder spraying tube 5 is sealed and inserted into the front end of the liquid outlet pipe 14, and the sealing is achieved by a sealing ring. After the windshield plug 6 is clamped to the end cover 7, the tapered through-hole at the rear inner side of the windshield plug 6 is in sealed contact with the tapered part at the front end of the rear end head 5B of the powder spraying tube 5 and limits the position, preventing the powder spraying tube 5 from being rushed out and falling by the airflow. Press the switch button 9, the fan 10 and the ion generator 18 are connected to the power supply 2, and both work at the same time. The gear position of the fan 10 is adjusted through the control panel 4, and the fan 10 generates airflow, as shown. Figure 6 and Figure 7 As shown by the arrows, ion emitter 11 generates a large amount of ionic charge, which travels with the airflow, passing through inlet check valve 13 and entering medicine pot 8. This neutralizes the static charge in the powder inside pot 8, preventing static aggregation and agglomeration. The powder then follows the airflow through air duct 21 of blower 12, liquid outlet pipe 14, and powder spray pipe 5, before being sprayed onto the target. Excess ions in the airflow continue to neutralize the target and surrounding objects, killing bacteria and other objects on contact. Simultaneously, the ions continuously absorb various microparticles in the air, such as dust and smoke, achieving PM2.5 reduction and deodorizing functions. Windshield plug 6 acts as a windshield.

[0065] The ion generator 18 can generate both positive and negative ions, or can generate only negative ions or only positive ions.

[0066] The ion spray powder spraying machine of this embodiment with static elimination function is a multifunctional spray powder sprayer, which is easy to use and has two functions. It can eliminate static agglomeration of powder, kill bacteria, improve the environment, reduce PM2.5, deodorize and remove odor.

[0067] This embodiment also provides a spray powder spraying method of an ion spray powder spraying integrated machine with a static elimination function, including a spraying method and a powder spraying method.

[0068] Spray methods include:

[0069] Install the liquid suction tube 19 on the main body: remove the medicine pot 8 connected to the lower side of the wind tube 12, seal the liquid suction tube 19 to the lower end of the air duct 21, and then connect the medicine pot 8 to the lower side of the wind tube 12;

[0070] Press the switch button 9 to connect the control panel 4, the fan 10 and the ion generator 18 to the power supply 2, and adjust the wind speed of the fan 10 through the control panel 4 as needed;

[0071] After the fan 10 is working, it generates airflow, which enters the internal cavity of the wind tube 12 from the rear end of the housing 1. At the same time, the ion generator 18 generates a large amount of ion charge through the ion emission end 11, and moves with the airflow. Part of the airflow passes through the air inlet check valve 13 and enters the medicine pot 8, applying positive pressure to the liquid medicine in the medicine pot 8. The other part of the airflow passes through the impeller 16 and flows out from the impeller through hole 16C in the middle of the impeller 16 and the end cover through hole 7A in the middle of the end cover 7, and forms a negative pressure at the end of the liquid outlet pipe 14. Under the action of positive and negative pressure differences, the liquid medicine in the medicine pot 8 passes through the liquid suction tube 19, the air duct 21 of the wind tube 12, and the liquid outlet pipe 14 in sequence, and is atomized and sprayed to the target under the action of the airflow coming out from the impeller through hole 16C in the middle of the impeller 16 and the end cover through hole 7A in the middle of the end cover 7; a large number of ions in the airflow continue to neutralize the target and surrounding objects, killing the bacteria they come into contact with, and at the same time, the ions continuously adsorb various microparticles in the air, thereby achieving the functions of reducing PM2.5, deodorizing and removing odors.

[0072] Powder spraying methods include:

[0073] Install the windshield plug 6 and the powder spraying tube 5 on the fuselage body: connect the windshield plug 6 to the end cover 7, and connect the powder spraying tube 5 to the inner hole of the windshield plug 6. At the same time, the powder spraying tube 5 is sealed and plugged with the front end of the liquid outlet pipe 14.

[0074] Press the switch button 9 to connect the control panel 4, the fan 10 and the ion generator 18 to the power supply 2, and adjust the wind speed of the fan 10 through the control panel 4 as needed;

[0075] After the fan 10 starts working, it generates airflow, which enters the internal cavity of the air duct 12 from the rear end of the shell 1. At the same time, the ion generator 18 generates a large amount of ion charges through the ion emitting end 11. A large amount of ion charges move with the airflow and enter the medicine pot 8 through the air inlet one-way valve 13, neutralizing the electrostatic charge in the powder in the medicine pot 8 to prevent the electrostatic agglomeration and agglomeration of the powder. Then the powder passes through the air duct 21, the liquid outlet pipe 14 and the powder spraying pipe 5 of the air duct 12 in turn with the airflow, and is finally sprayed to the target; the large amount of excess ions in the airflow continue to neutralize the target and surrounding objects, killing the bacteria they come into contact with. At the same time, the ions continuously adsorb various microparticles in the air, thereby achieving the functions of reducing PM2.5, deodorizing and removing odors.
