Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] like Figures 1-2 As shown, an electrostatic atomizer host proposed in one embodiment of the present invention includes a housing 100, a water pump 500 disposed within the housing 100, a nozzle assembly 200 fixed within the housing 100, an adjustment assembly 300, and an electrostatic module. The adjustment assembly 300 is connected to the water pump 500 via a pipe and is also connected to the nozzle assembly 200. The electrostatic module includes an electrostatic control switch (not shown in the figure), an electrostatic generator (not shown in the figure), and an electrostatic charging electrode 600. The electrostatic charging electrode 600 is electrically connected to the electrostatic generator and is disposed on the outside of the nozzle assembly 200 to charge the sprayed droplets. The adjusting assembly 300 includes an adjusting shaft 310 that can rotate along the axis 301. A liquid flow channel is provided through the adjusting shaft 310. The liquid flow channel includes an inlet connected to the water pump 500 and an outlet 3111 that is eccentrically arranged relative to the axial direction. The nozzle assembly 200 is provided with a plurality of nozzles 211. The plurality of nozzles 211 are circumferentially distributed on the nozzle assembly 200. Rotating the adjusting shaft 310 can make the outlet 3111 correspond to any one of the plurality of nozzles 211.

[0048] Specifically, to ensure that the rotating adjusting shaft 310 can align the eccentrically positioned outlet 3111 with any one of the multiple nozzles 211, the multiple nozzles 211 are equidistant from the shaft center 301 and circumferentially distributed on the nozzle assembly 200. The multiple nozzles 211 have the same size, and the axial centerlines of the multiple nozzles 211 are equidistant from the shaft center 301. The eccentricity of the outlet 3111 relative to the shaft center 301 is equal to the aforementioned vertical distance, so that the eccentrically positioned outlet 3111 can align with any one of the multiple nozzles 211 when rotating along the shaft center 301.

[0049] According to the electrostatic atomizer main unit of this embodiment, an adjusting shaft 310 is provided that can rotate along the axis 301 and has a liquid flow channel passing through it. The liquid outlet 3111 of the adjusting shaft 310 is eccentrically arranged relative to the axial direction and is circumferentially distributed on the nozzle assembly 200. Rotating the adjusting shaft 310 can make the liquid outlet 3111 correspond to any one of the multiple nozzles 211, which makes it convenient for the operator to select the appropriate nozzle according to different biological targets and different types of pesticides, so that the electrostatic atomizer can spray out atomized liquid particles of appropriate size.

[0050] The mist particle size of the electrostatic atomizer host in the embodiment is in the range of 10-400 microns after the mist particle is charged by the electrostatic charging electrode; preferably, the mist particle size is in the range of 20-200 microns. By providing a plurality of different nozzles 211, a plurality of selectable mist particle sizes after being charged by the electrostatic charging electrode are provided, which facilitates the operator to adjust the appropriate gear according to different biological targets and different types of pesticides. For example, the mist particle size can be at least part of the following: about 20 microns, about 50 microns, about 80 microns, about 120 microns, about 160 microns, about 200 microns, etc.; the plurality of nozzles 211 can also include a large-flow exhaust nozzle to quickly exhaust the air in the water pump 500 and / or the pipeline.

[0051] Preferably, the adjustment assembly 300 further comprises a water pump connector 320 fixed to the shell 100, and the adjustment shaft 310 further comprises a liquid inlet portion 312, and the water pump connector 320 is connected to the water pump 500 and the liquid inlet portion 312. Specifically, the water pump connector 320 is connected to the water pump 500 through a pipeline, the adjustment shaft 310 is in clearance fit with the water pump connector 320, the adjustment shaft 310 is provided with a first groove 3121 for installing a sealing ring, the adjustment shaft 310 is inserted into the water pump connector 320, the adjustment shaft 310 is sealed relative to the water pump connector 320, and the adjustment shaft 310 is rotatable relative to the water pump connector 320 along the shaft center 301. More preferably, the water pump connector 320 is provided with a second groove 321 for installing a sealing ring.

[0052] In the preferred embodiment, by providing the water pump connector 320 in the adjustment assembly 300, and the water pump connector 320 is fixed to the shell 100, the rotation of the adjustment shaft 310 avoids the twisting of the pipeline between the adjustment assembly 300 and the water pump 500, so that the liquid cannot pass through or the pipeline is disconnected due to excessive twisting.

[0053] In order to prevent the displacement of the adjustment shaft 310 from causing the liquid outlet 3111 to be unable to correspond to the nozzle 211, as shown in Figure 3 、 Figure 4 The nozzle assembly 200 further comprises a limiting cavity 230, the adjustment shaft 310 comprises a liquid outlet portion 311 provided with a liquid outlet 3111, the liquid outlet portion 311 is limited in the limiting cavity 230, and the adjustment shaft 310 is rotatable relative to the limiting cavity 230 along the shaft center 301.

[0054] The nozzle assembly 200 further comprises a nozzle seat 210 and a nozzle sleeve 220, which are detachably fixedly connected to form a limiting cavity 230 therebetween, so as to facilitate the operator to install the adjusting assembly 300 into the nozzle assembly 200. Specifically, the nozzle seat 210 and the nozzle sleeve 220 are correspondingly provided with threads, and are fixedly connected through the threads. The nozzle seat 210 has a space inside, and the limiting cavity 230 is formed between the nozzle seat 210 and the nozzle sleeve 220. The third groove 3112 for installing the sealing ring is arranged on the annular portion of the adjusting shaft 310. The adjusting shaft 310 is inserted into the nozzle sleeve 220, and is sealed with the nozzle sleeve 220, and then the nozzle seat 210 and the nozzle sleeve 220 are fixedly connected to complete the installation. The plurality of nozzles 211 are detachably arranged on the nozzle seat 210. Specifically, a plurality of threaded holes equidistant to the shaft center 301 are arranged on the nozzle seat 210 in the circumferential direction. The plurality of nozzles 211 are fixedly connected with the nozzle seat 210 through the threaded holes and are distributed on the nozzle seat 210 in the circumferential direction, so as to facilitate the disassembly, cleaning, maintenance and replacement of the plurality of nozzles 211.

[0055] The nozzle seat 210 is further provided with a sealing gasket made of flexible material. The nozzle seat 210 is provided with a limiting portion for limiting the rotation of the sealing gasket. The sealing gasket is positioned in the nozzle seat 210 through the limiting portion. The sealing gasket is provided with holes corresponding to the plurality of nozzles 211. The liquid outlet portion 311 is arranged in the nozzle sleeve 220. The nozzle seat 210 is fixedly connected with the nozzle sleeve 220 through the threads. The nozzle seat 210 is pressed against the liquid outlet portion 311 through the sealing gasket. The sealing gasket is arranged between the liquid outlet 3111 and the nozzle 211 to seal them, so as to avoid the liquid in the liquid outlet 3111 from being sprayed out of other nozzles 211 through the gap, thereby affecting the atomization effect. It can be understood that the vertical distance between the axial center line of the plurality of nozzles 211 and the shaft center 301 is not completely equal by arranging the sealing gasket between the liquid outlet 3111 and the nozzle 211. Only the corresponding plurality of through holes on the sealing gasket and the corresponding through holes in each of the plurality of nozzles 211 and the nozzle 211 are at least partially overlapped, and the overlap can ensure the required flux of the spray. The vertical distance between the axial center line of the plurality of nozzles 211 and the shaft center 301 is not completely equal, for example, due to the size deviation caused by the machining error, or the plurality of nozzles 211 are arranged in an asymmetric manner to present a special visual effect.

[0056] As Figures 1-2As shown in one of the embodiments of the present application, based on the electrostatic atomizer host machine proposed in the foregoing embodiment, the adjusting assembly 300 further comprises an adjusting part 330. By arranging the adjusting part 330, and the adjusting part 330 rotating with the adjusting shaft 310, and the notch 110 on the shell 100 allowing the adjusting part 330 to pass through, the operator can switch the nozzle at any time. Considering that the front end of the nozzle assembly 200 is provided with the electrostatic charging electrode 600, it is not convenient to switch the nozzle 211 by directly rotating the nozzle assembly 200, so the adjusting shaft 310 corresponding to the nozzle 211 is rotated to adjust, which is more convenient for the operator to operate. At the same time, considering that there is a strong electric field on the electrostatic charging electrode 600, even if the electrostatic control switch is turned off, the electric field will not disappear immediately, and the high-voltage charge on the electrostatic charging electrode 600 needs to be carried away by continuous spraying to gradually disappear. Therefore, the adjusting part 330 for switching the nozzle is arranged on the adjusting assembly 300 away from the electrostatic charging electrode 600, which reduces the risk of the operator accidentally touching the high-voltage electrostatic charging electrode 600 or being electrocuted by approaching the high-voltage electrostatic charging electrode 600.

[0057] Specifically, as Figures 2-4 shown, the adjusting part 330 is a knob, the adjusting shaft 310 is provided with a rotation stopping part 340, the knob is correspondingly provided with a through hole corresponding in shape to the rotation stopping part 340, the rotation stopping part 340 cooperates with the through hole to limit the circumferential rotation of the adjusting shaft 310 and the knob, and the adjusting shaft 310 rotates with the knob when the knob is rotated. The adjusting shaft 310 is further provided with a protruding stepped part 350, the stepped part 350 limits the movement of the knob along the axial direction to the liquid outlet part 311, and the water pump connector 320 is dampedly connected with the adjusting shaft 310 through the sealing ring arranged in the first groove 3121 and the second groove 321 to limit the movement of the knob along the axial direction to the liquid inlet part 312. The knob is limited between the water pump connector 320 and the stepped part 350 and has almost no play, so as to reduce the left and right shaking of the knob on the adjusting shaft 310.

[0058] As Figures 1-3 shown, in one of the embodiments of the present application, based on the electrostatic atomizer host machine proposed in the foregoing embodiment, the nozzle part and the adjusting shaft 310 are provided with a positioning assembly 400, and the positioning assembly 400 positions the adjusting shaft 310 when the liquid outlet 3111 corresponds to any one of the plurality of nozzles 211.

[0059] Specifically, the positioning assembly 400 includes a plurality of positioning grooves 410 formed in the inner wall of the nozzle sleeve 220, a positioning cavity 420 formed in the adjusting shaft 310, and a ball 430 and a return spring 440 disposed in the positioning cavity 420, wherein the plurality of positioning grooves 410 are consistent in number and one-to-one corresponding in position with the plurality of nozzles 211. The operator rotates the adjusting assembly 300, the ball 430 slides along the inner wall of the nozzle sleeve 220, at this time the return spring 440 is compressed and stores energy, when the liquid outlet 3111 is aligned with any one of the plurality of nozzles 211, the positioning cavity 420 corresponds in position with the positioning groove 410, the return spring 440 releases and pushes the ball 430 into the positioning groove 410, the ball 430 collides with the positioning groove 410 and emits a collision sound, reminding the operator to rotate to the right position; the ball 430 is limited in the positioning groove 410, the adjusting shaft 310 is not easy to rotate, avoiding that the liquid outlet 3111 does not correspond to the nozzle 211 to reduce the liquid passage and affect the atomization effect. At the same time, the hand feels obvious damping when rotating the adjusting assembly 300, further reminding the operator that the adjusting assembly 300 has been aligned with the nozzle 211. The operator continues to rotate the adjusting assembly 300, the ball 430 moves upward along the edge of the positioning groove 410, pushing the return spring 440 to be compressed and store energy, the operator can repeat the above operation until switching to the appropriate nozzle 211.

[0060] In this embodiment, by setting the positioning assembly 400 between the nozzle assembly 200 and the adjusting shaft 310, when the liquid outlet 3111 is aligned with one of the plurality of nozzles 211, the positioning assembly 400 dampens and positions the adjusting shaft 310 when the operator rotates the adjusting assembly 300. Further, by using the positioning groove 410, the positioning cavity 420, and the ball 430 and the return spring 440 disposed in the positioning container, the structure is simple and stable, not easy to malfunction and low in production cost, at the same time, when the nozzle is aligned, the ball 430 is limited in the positioning groove 410, the adjusting shaft 310 is not easy to displace, avoiding that the liquid outlet 3111 is not aligned with the nozzle 211 to cause water leakage, at the same time, the adjusting assembly 300 has obvious damping when rotating, further reminding the operator that the nozzle 211 has been aligned.

[0061] As shown in the figure, Figure 5 In one embodiment of the present application, an electrostatic atomizer is provided, which comprises a water tank 700 and an electrostatic atomizer main machine as described in any of the above embodiments.

[0062] In this embodiment, the water tank 700 is detachably fixed to the shell 100 of the electrostatic atomizer main machine, which is convenient for the operator to add liquid and replace the water tank 700 of different sizes as needed; the water pump 500 is provided with a liquid pumping pipeline 510 extending into the water tank 700, which can extract as much liquid as possible from the water tank 700, avoiding the operator to repeatedly add liquid.

[0063] In another preferred embodiment, asFigure 6 As shown, the water tank 700 is connected with the shell 100 through the external pipeline 730, the shell 100 is provided with the host water inlet 120 communicated with the water pump 500, the water tank 700 is provided with the water tank water outlet 720, the host water inlet 120 and the water tank water outlet 720 are communicated through the external pipeline 730. Wherein the water inlet 120 and the water outlet 720 are quick connectors, so as to facilitate the operator to plug and replace the external pipeline 730. By adopting the external pipeline 730 with sufficient length, the operator can carry the water tank 700 on the back and spray the water by hand.

[0064] In order to facilitate carrying, the host and the split water tank 700 are provided with the clamping structure 800, the host is hung on the water tank 700 through the clamping structure 800. Specifically, the water tank 700 is provided with the first clamping part 810, the bottom of the shell 100 is provided with the second clamping part 820, the second clamping part 820 is clamped on the first clamping part 810, so that the host is clamped on the water tank 700, so as to improve the portability of the electrostatic atomizer, and facilitate the operator to hang the water tank 700 and the host together when not spraying.
