Description

Technical Field

[0001] This utility model specifically relates to an electric electrostatic sprayer with multiple discharge electrodes. Background Technology

[0002] Electrostatic spraying technology utilizes the principle of electrostatic adsorption, enabling droplets to achieve 360-degree encirclement and adsorption on the target, thus improving the utilization rate of the spray solution. Backpack-mounted electric electrostatic sprayers are a common application device. Their working principle involves charging the liquid while simultaneously imbuing the target with an opposite charge, achieving the encirclement and adsorption effect of the spray solution on the target through the attraction of opposite charges. The process is as follows: a high-voltage generator applies high-voltage electrostatics to the charging electrode in the liquid reservoir, giving the spray solution a negative charge; simultaneously, the operator holds a handle connected to the positive electrode, making their body a conductor and conducting the positive charge to the ground, ultimately giving the target on the ground a positive charge. The negatively charged spray droplets are then adsorbed onto the positively charged target surface under the influence of the electric field, forming an "electrostatic encirclement."

[0003] However, this technology has the following drawbacks:

[0004] 1) Safety hazard: The operator's skin needs to come into direct contact with the high-voltage electrodes, which poses a risk of electric shock;

[0005] 2) Unstable effect: Poor contact between the skin and the electrode (such as sweating or changes in grip posture) can lead to interruption of charge conduction and weaken the adsorption effect;

[0006] 3) Low reliability: The grounding path of the human body is affected by factors such as the insulation of the shoe sole and the humidity of the ground, resulting in insufficient charging of the target object.

[0007] To address these issues, existing technologies propose air ionization grounding as an alternative to human body conduction: ionizing the air at the tip of a discharge electrode allows charged particles in the air to conduct charge to the target. However, practical experience shows that single electrodes still suffer from insufficient ionization intensity and limited coverage, resulting in uneven target charging and significant fluctuations in the suffocation effect in complex environments.

Detailed Implementation

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] In the description of this utility model, it should be understood that the terms "left," "right," etc., indicating the orientation or positional relationship are based on the accompanying drawings. Figure 1The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In order to achieve the purpose of this utility model, such as Figure 1 As shown in this embodiment, an electric electrostatic sprayer with multiple discharge electrodes is disclosed in this utility model, including: a liquid storage tank 1, a water pump 2, a spray bar 3, a high-voltage generator 41, a storage battery 42, and a liquid charging electrode 43 disposed at the bottom of the liquid storage tank 1; one high-voltage output terminal of the high-voltage generator 41 is electrically connected to the liquid charging electrode 43, and the other high-voltage output terminal is electrically connected in parallel to two air ionization discharge electrodes 5; the air ionization discharge electrodes 5 are exposed to the air and conduct the charge to the ground and the target object by ionizing the air.

[0034] The top of the aforementioned storage tank 1 is equipped with a filling port, which is threadedly connected to a tank cover 11. A filter screen 12 is installed inside the filling port. The inlet of the water pump 2 is connected to the interior of the storage tank 1 via an inlet hose 21, and the outlet of the water pump 2 is connected to the spray bar 3 via an outlet hose 22. The spray bar 3 is equipped with a handle 31, a nozzle 32, and a spray nozzle 33. After the water pump 2 starts working, it draws the liquid medicine from the storage tank 1 into the pump chamber through the inlet hose 21. After being pressurized, the liquid medicine is sprayed out from the spray nozzle 33 through the outlet hose 22.

[0035] A charging port 61 electrically connected to the battery 42 and a switch 62 for controlling the battery 42 are provided on the side of the bottom of the liquid storage tank 1.

[0036] The principle of air ionization grounding is that high-voltage static charge is conducted through a wire to a charge release electrode. The tip 52 of the release electrode releases static charge to the air, ionizing the air within a certain range. Because the air contains numerous tiny particles and a certain amount of moisture, these water-containing tiny particles can be ionized and quickly acquire a static charge. At the same time, they can rapidly conduct the static charge to the target object, which is also exposed to the air, thus giving the target object a polar static charge.

[0037] This invention connects one output terminal of a high-voltage generator 41 to a liquid charging electrode 43 and two air ionization discharge electrodes 5 in parallel to the other output terminal. By using multiple discharge electrodes to enhance the air ionization intensity, the target material is charged more fully and stably, solving the problem of insufficient ionization in traditional single-electrode systems and significantly improving the circumferential adsorption effect of electrostatic spraying. At the same time, the air ionization method eliminates the risk of electrostatic stimulation by eliminating human contact with the electrodes and improving equipment safety.

[0038] To further optimize the implementation effect of this utility model, in another embodiment of this utility model, based on the foregoing content, as follows: Figure 2 As shown, the air ionization discharge electrode 5 is a carbon fiber bundle, and its tip 52 is a branched filament structure.

[0039] The end 51 of the air ionization discharge electrode 5 is electrically connected to the high voltage output terminal, and the tip 52 serves as the electrostatic discharge terminal.

[0040] The above-described embodiments have the following effects: the electrostatic discharge electrode is made of carbon fiber bundles, which are composed of numerous carbon fiber filaments, thus having numerous discharge terminals to air, and therefore have a better effect on ionizing air.

[0041] Using carbon fiber bundles as discharge electrodes, the branched filament structure increases the number of discharge tips 52, further enhancing air ionization efficiency; the design of the end 51 connecting to the high voltage output end and the tip 52 serving as the discharge end ensures a clear charge conduction path, reduces energy loss, and improves the synergy between drug charge and target charge, thereby enhancing adsorption stability.

[0042] To further optimize the implementation effect of this utility model, in another embodiment of this utility model, based on the foregoing content, as follows: Figure 3-4 As shown, an insulating sleeve 71 is installed on the outside of the air ionization discharge electrode 5, and an insulating shell 72 is installed on the outside of the insulating sleeve 71. The insulating shell 72 is connected to the liquid storage tank 1.

[0043] The above-described embodiments have the following effects: the discharge electrode is protected by a double layer of insulating sleeve 71 and insulating shell 72, which not only avoids short circuits or charge leakage caused by accidental contact between the electrode and external objects, but also prevents the electrode from being directly corroded by liquid and water vapor, thus extending the service life of the electrode; the connection design between the insulating shell 72 and the liquid storage tank 1 makes the electrode installation more stable and adaptable to the bumpy working environment of backpack equipment.

[0044] Furthermore, based on the above embodiments, the opening of the insulating shell 72 is a tapered expansion opening.

[0045] The above-described embodiments have the following effects: the conical expansion opening of the insulating shell 72 can guide the ionized charged air to diffuse towards the target, reduce the accumulation loss of charge near the shell, and enhance the efficiency of transporting charged particles to the target.

[0046] like Figure 5 As shown, further, based on the above embodiments, the air ionization discharge electrode 5, the insulating sleeve 71 and the insulating shell 72 constitute a detachable connection module, and the detachable connection module and the liquid storage tank 1 are magnetically connected through a quick-connect component.

[0047] The above-described embodiments have the following effects: the detachable connection module design facilitates the individual replacement, cleaning or maintenance of the discharge electrode, reducing equipment maintenance costs; the magnetic quick-connect assembly enables the insulating shell 72 to quickly connect with the liquid storage tank 1, eliminating the cumbersome operation of traditional screw fixing, improving the user's installation or disassembly efficiency, and is especially suitable for rapid adjustment during field operations.

[0048] Furthermore, based on the above embodiments, the quick-connect component includes: a first magnet 81 disposed at the bottom of the insulating housing 72, a second magnet 82 disposed at the corresponding position of the liquid storage tank 1, a first conductive pin 91 electrically connected to the end 51 of the air ionization discharge electrode 5, and a second conductive pin 92 electrically connected to the high voltage output terminal of the high voltage generator 41.

[0049] The magnetic poles of the first magnet 81 and the second magnet 82 are configured to attract each other. When the first magnet 81 and the second magnet 82 are attracted, the first conductive pin 91 and the second conductive pin 92 automatically connect and become conductive.

[0050] The above-described embodiments have the following effects: by utilizing the attraction characteristics of opposite poles of the first magnet 81 and the second magnet 82, the insulating shell 72 and the liquid storage tank 1 are precisely positioned, while the first conductive pin 91 and the second conductive pin 92 are automatically connected and made conductive, ensuring reliable connection of the high-voltage circuit; the synergistic design of magnetic attraction and conductive pins simplifies the connection steps and avoids the problem of manually inserting and removing pins for alignment, reducing the risk of poor contact.

[0051] Furthermore, based on the above embodiments, the bottom of the insulating shell 72 is provided with a first groove, and the first magnet 81 is embedded and fixed in the first groove; the side wall of the liquid storage tank 1 is provided with a second groove, and the second magnet 82 is embedded and fixed in the second groove.

[0052] The above-described embodiments have the following effects: embedding the magnet into the first groove of the insulating housing 72 and the second groove of the liquid storage tank 1 makes the magnet more securely installed and prevents the magnet from falling off during operation; the groove structure can also reduce direct collision between the magnet and external objects, protect the magnetic stability of the magnet, and extend the service life of the quick-connect assembly.

[0053] Furthermore, based on the above embodiments, the quick-connect assembly also includes an interlocking buckle structure (not shown in the figure), which is used to interlock after the insulating housing 72 is magnetically connected to the liquid storage tank 1.

[0054] In some embodiments, the interlocking latch structure may include:

[0055] The elastic latch located at the bottom of the insulating housing 72 has a wedge-shaped protrusion at its end 51.

[0056] The slot located at the corresponding position of the liquid storage tank 1 has a locking notch on its side wall that matches the wedge-shaped protrusion;

[0057] When the first magnet 81 and the second magnet 82 are attracted to each other, the wedge-shaped protrusion engages with the locking recess, forming a mechanical lock; pressing the elastic latch causes the wedge-shaped protrusion to disengage from the locking recess, releasing the mechanical lock.

[0058] The interlocking buckle structure and the magnetic suction component satisfy the following cooperative relationship:

[0059] Magnetic attraction provides initial adsorption and positioning, allowing the card tongue to be initially aligned with the card slot;

[0060] The interlocking buckle automatically locks after adsorption, resisting separation by external force;

[0061] To unlock, you must first press the latch to release the mechanical lock, and then apply a separating force to overcome the magnetic attraction.

[0062] The interlocking buckle structure described above can also take other forms; the above is just one example.

[0063] The above-described implementation method has the following effects: the interlocking buckle structure further achieves mechanical locking after magnetic connection, preventing the insulating shell 72 from separating from the liquid storage tank 1 due to equipment vibration or accidental collision, ensuring continuous conduction of the conductive pin and stable operation of the discharge electrode; the double fixation improves the anti-detachment capability of the connection module and adapts to the usage requirements of complex field environments.

[0064] This utility model discloses an electric electrostatic sprayer with multiple discharge electrodes, which has the following advantages compared with the prior art:

[0065] First, this invention employs two or more air ionization discharge grounding electrodes, which can increase the intensity of ionization discharge, effectively guarantee and enhance the enveloping adsorption effect of electrostatic spraying, and ensure the stability of the electrostatic spraying effect.

[0066] Secondly, this utility model adopts a quick-connect design with magnetic attraction and buckle of detachable connection module, which realizes quick disassembly and maintenance of electrodes, reduces the difficulty of user operation, and meets the high-efficiency needs of farmers in field operations.

[0067] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
