Description

TECHNICAL FIELD

[0001] The present application relates to the field of spray equipment, in particular to a static spray device. BACKGROUND

[0002] The basic working principle of the existing static spray device is that a static generator is arranged in the static spray device, the static generator has two electrodes, one electrode is connected to a solution tank to enable the liquid to have corresponding electric charge, and the other electrode is connected to the hand-held position of the spray device; when the user turns on the switch and simultaneously applies power, the electric charge of the electrode is released through the human body; the mist droplets have static charge, and the mist droplets are more easily adsorbed to the target object under the action of the static charge, thereby effectively improving the spray efficiency. This method of releasing electric charge through the human body must require the user's hand to be in good conduction with the electrode to release the electric charge through the human body; if the user wears gloves or other insulating objects to separate the two, the electrode cannot effectively release the electric charge, and the electrode in contact with the liquid also cannot effectively release the electric charge. At this time, the effect of improving the efficiency of spray static adsorption cannot be achieved; one electrode is directly connected to the solution tank, and after the solution is charged, the solution needs to pass through the solution tank, the suction pipe, the connecting pipe, the diaphragm pump, and then pass through the spray head assembly to be sprayed out; since the static ion liquid has a timeliness, the static ion liquid is prone to discharge and disappear in the liquid and the channel; the longer the time of the solution in the solution and the time in the channel, the less the amount of ions carried, and the worse the effect of static adsorption generated.

[0030] Please refer to Figures 1-3 and Figure 7 The present invention provides an electrostatic sprayer, comprising a sprayer body 10 and a handheld part 20 connected to the sprayer body 10. One end of the sprayer body 10 is provided with a nozzle assembly 11, and the other end is provided with an electrostatic switch 12. Inside the sprayer body 10, there is an ion generator 13, a diaphragm pump 14, and an electrostatic electrode 15. A discharge needle 16 and a light 18 are connected to the outer shell of the sprayer body 10. A solution container 17 is connected to the bottom of the sprayer body 10. A power switch 21 and a waterproof battery pack 22 are provided on the handheld part 20. The ion generator 13, electrostatic electrode 15, electrostatic switch 12, power switch 21, discharge needle 16, light 18, and waterproof battery pack 22 are connected by a wire 30. The solution container 17, diaphragm pump 14, electrostatic electrode 15, and nozzle assembly 11 are connected by a water pipe 40. The solution in the solution container 17 flows to the electrostatic electrode 15 through the water pipe 40, and after being energized, is sprayed out through the nozzle assembly 11.

[0031] Specifically, the sprayer body 10 is horizontally positioned, and the electrostatic switch 12 is located at the rear of the sprayer body 10, that is... Figures 1-2 The left end of the sprayer body 10 is used to control the activation of the ion generator 13. The nozzle assembly 11 is located at the head of the sprayer body 10, that is... Figures 1-2 At the right end of the sprayer body 10, in this embodiment, the nozzle assembly 11 is a rotatable three-in-one nozzle assembly with three nozzles. Each nozzle has a different spray shape and effect. The three nozzles are evenly arranged on the nozzle assembly, and the appropriate nozzle is selected by rotating the nozzle assembly according to the desired spray shape and effect. A handheld part 20 is located at the bottom of the sprayer body 10 near the electrostatic switch 12, allowing the operator to control the sprayer body 10. A solution reservoir 17 is located at the bottom of the sprayer body 10 near the nozzle assembly. The solution in the reservoir 17 flows through a water pipe 40 to the nozzle assembly 11 and is then sprayed out. A waterproof battery pack 22 is located at the bottom of the handheld part 20, providing power for the entire sprayer body 10. A power switch 21 controls the power supply. A discharge needle 16 is fixed to the outer casing of the sprayer body 10 near the electrostatic switch 12, and the discharge needle 16 can serve as a conductor. The lighting lamp 18 is a high-brightness LED light, which is located on the top of the sprayer body 10 near the nozzle assembly 11, facilitating nighttime operation of the sprayer. A lamp cover is provided on the outside of the lighting lamp 18, and sealant is applied to the rear end of the lamp cover to seal the lighting lamp 18. It should be noted that... Figure 7 The power source is the waterproof battery pack 22 that provides electrical energy, and the main switch is the power switch 21.

[0032] Specifically, the wire 30 includes a first wire 31, a second wire 32, and a third wire 33. One end of the first wire 31 is connected to the ion generator 13, and the other end is connected to the electrostatic electrode 15. One end of the second wire 32 is connected to the ion generator 13, and the other end is connected to the power switch 21. One end of the third wire 33 is connected to the ion generator 13, and the other end is connected to the discharge needle 16. When both the electrostatic switch 12 and the power switch 21 are turned on, the electrostatic electrode 15, the discharge needle 16, and the power switch 21 act as conductors, forming two paths for discharge grounding. Both ends can be point discharge, both can be human body discharge, or one path can discharge through the human body and the other path can be point discharge. This discharge method can avoid the power switch 21 being insulated due to the operator wearing gloves or other means, which would affect the electrostatic release effect and thus affect the electrostatic release at the nozzle assembly 11, thus affecting the electrostatic spray effect.

[0033] Specifically, the water pipe 40 includes an outlet pipe 41 and an inlet pipe 42. One end of the inlet pipe 42 is connected to the solution reservoir 17, and the other end is connected to the diaphragm pump 14, forming an inlet channel. One end of the outlet pipe 41 is connected to the diaphragm pump 14, and the other end is connected to the nozzle assembly 11, forming an outlet channel. An electrostatic electrode 15 is embedded inside the outlet pipe 41, with its inner side exposed. The electrostatic electrode 15 directly contacts the liquid in the pipe, charging the liquid before it is directly sprayed out through the nozzle assembly 11. The solution ions, upon direct contact with the electrostatic electrode 15, immediately become charged and are sprayed directly out through the nozzle assembly 11, significantly shortening the time and distance the charged liquid travels through the channel. This prevents the ion concentration in the channel from decaying or neutralizing due to time, increasing the amount of ions in the spray and thus improving the adsorption effect.

[0034] Please refer to Figures 1-2 and Figure 5 The solution container 17 is equipped with a straw assembly 50. One end of the water inlet pipe 42 is connected to the straw assembly 50 via a straw connector assembly 60 to form a water inlet channel. The outer periphery of the mouth 171 of the solution container 17 is provided with a first thread. The lid 172 is fixed to the bottom of the sprayer body 10. The inside of the lid 172 is also provided with a second thread corresponding to the first thread. The solution container 17 is detachably installed at the bottom of the sprayer body 10 by the engagement of the first thread on the mouth 171 and the second thread on the lid 172. The top of the lid 172 is also provided with a fixing hole 173. On both sides of the fixing hole 173, there are small ventilation holes 174 respectively. A fixing hole plug 175 is installed in the fixing hole 173. The bottom outer edge of the fixing hole plug 175 can cover the small ventilation holes 174. When the electrostatic sprayer is not working, the fixing hole plug 175 fits and seals the fixing hole 173. The bottom of the fixing hole plug 175 can cover the small ventilation holes 174 and seal the small ventilation holes 174. When the electrostatic sprayer is working, a suction force is generated in the entire solution container 17. At this time, the fixing hole plug 175 moves down, the small ventilation holes 174 are opened and air is introduced, so that no negative pressure is generated in the entire solution container 17, and the water inlet pipe 42 can normally draw in the liquid in the solution container 17.

A first spring guide rib 223a is provided at the center of the side of the mounting button 223 facing the connector 224, and a second spring guide rib 224a is also provided at the center of the side of the connector 224 facing the mounting button 223. One end of the spring 226 is fixed to... The connector 224 is fitted onto the first spring guide rib 223a at one end and onto the second spring guide rib 224a at the other end. A guide portion 223b extending vertically toward the connector 224 is provided at one end of the mounting button 223. A downwardly recessed guide groove 224b is provided on the connector 224 at a position corresponding to the guide portion 223b, allowing the mounting button 223 to move up and down with guidance. A third U-shaped groove 221c is provided at the outer end of the upper shell 221 near the solution vessel 17, with the opening of the third U-shaped groove 221c facing...

One end of the plug assembly 225 connects to the battery electrode plates inside the battery pack 227, and the other end is connected to functional components such as the power switch 21 via a wire 30. A predetermined number of serrated third sealing rings 221d are provided at the contact point between the plug assembly 225 and the third U-shaped groove 221c, enabling both detachable movement and a fixed seal between the waterproof battery pack 22 and the plug assembly 225. Through this sealing design, the waterproof battery pack 22 achieves an IPX5 waterproof rating, effectively preventing electrical safety issues caused by water ingress into the battery cells and related conductors.

[0036] As described above, the electrostatic sprayer provided by this invention, through the design of the discharge needle, allows for at least two paths of discharge grounding. Both ends can be tip discharge, human body discharge, or one path through the human body and the other through a tip discharge. This design avoids the impact of users wearing gloves or other methods that insulate the power switch, thus preventing interference with the electrostatic discharge at the nozzle end and affecting the electrostatic spraying effect.
