Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to a nozzle electrode waterproof protection device for spraying medicine. Background Art

[0002] Electrostatic spraying technology is a new type of pesticide application technology developed on the basis of droplet control technology and ultra-low volume spray theory and practice. Compared with conventional spraying technology, electrostatic spraying can achieve directional spraying, reduce pesticide drift, reduce environmental pollution, improve pesticide utilization, and save pesticide application costs.

[0003] Electrostatic spray technology uses electrodes to apply high-voltage static electricity to the nozzle, establishing an electrostatic field between the nozzle and the target. The liquid medicine is atomized by the nozzle and becomes charged, forming a group of charged droplets, which then move in a directed manner under the combined action of the electrostatic field and other external forces and are adsorbed to various parts of the target.

[0004] The patent with announcement number CN202219215U discloses "an electrode used in an electrostatic spray device, installed in the nozzle part of the electrostatic spray device that converts the liquid medicine into countless droplets for spraying. The electrode described in the utility model can be suitable for the modification and use of a spray device that is not yet equipped with an electrostatic function for charging the droplets sprayed from the nozzle part. It has a simple structure and low cost, good anti-leakage effect, and can obtain a satisfactory electrostatic spray effect."

[0005] With respect to the above-mentioned related technologies, the inventors believe that under the influence of external forces such as wind, the liquid medicine sprayed from the nozzle will inevitably contact the exposed annular electrode. After the liquid medicine contacts the annular electrode for a long time, the medicine in the liquid medicine will cause scaling on the annular electrode, affecting the performance of the annular electrode. In addition, factors such as the salt content, hardness, and acidity and alkalinity in the liquid medicine will affect the durability of the annular electrode. For example, liquid medicine containing high salt content or hardness will accelerate the corrosion rate of the annular electrode, causing the annular electrode to be easily damaged. Therefore, there is room for improvement. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a waterproof protection device for a spray nozzle electrode. The specific technical solution is as follows:

[0007] A nozzle electrode waterproof protection device for spraying medicine, comprising a nozzle body, an annular electrode installed on one side of the nozzle body for releasing electric charge to generate static electricity, and a protection mechanism installed on one side of the nozzle body for waterproofing the annular electrode, wherein the protection mechanism comprises an insulating cover arranged on one side of the nozzle body for covering the annular electrode, and an annular conductive substrate arranged on one side of the insulating cover for conducting the electric charge released by the annular electrode;

[0008] A scraping mechanism is arranged in the insulating cover, and the scraping mechanism comprises an L-shaped rod rotatably arranged in the insulating cover, and an insulating scraper fixed at one end of the L-shaped rod for scraping off scale on the annular conductive substrate.

[0009] The annular electrode can be waterproofed by the insulating cover and the annular conductive substrate so that the annular electrode will not directly contact the liquid medicine. By rotating the L-shaped rod, the insulating scraper can be driven to rotate and the scale on the annular conductive substrate can be scraped off.

[0010] Optionally, a plurality of connecting rods are fixed between the outer wall of the nozzle body and one side of the insulating cover, a first annular groove is opened on the inner side of the insulating cover, the annular electrode is fixed on the inner side of the first annular groove, the annular conductive substrate is fixed on the opening side of the first annular groove, and the outer wall of the annular conductive substrate is in cooperation and abutment with the inner wall of the annular electrode.

[0011] The nozzle body and the insulating cover can be connected via a connecting rod, and the annular electrode is covered between the insulating cover and the annular conductive substrate, so that the annular electrode will not directly contact with external liquid medicine.

[0012] Optionally, a second annular groove is provided on the inner side of the insulating cover, a circular ring is rotatably connected in the second annular groove of the insulating cover, the L-shaped rod is fixed on the inner wall of the circular ring, the insulating cover can be connected to the circular ring through the second annular groove, and the circular ring can connect the L-shaped rod and the insulating cover, so that the L-shaped rod can rotate on the insulating cover without falling off.

[0013] Optionally, an elastic rubber block that cooperates and abuts against the outer wall of the insulating cover is fixed on one side of the L-shaped rod, and an insulating sleeve for people to hold is fixed on the outer wall of one end of the L-shaped rod away from the insulating scraper, and the outer wall of the insulating sleeve is provided with anti-slip grooves.

[0014] The elastic rubber block abuts against the insulating cover under elasticity to fix the rotated L-shaped rod.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The insulating cover and the annular conductive substrate can provide waterproof protection for the annular electrode, so that the annular electrode will not directly contact the chemical solution, thereby avoiding corrosion by the chemical solution and extending the service life of the annular electrode. By rotating the L-shaped rod, the insulating scraper can be driven to rotate and scrape off the scale on the annular conductive substrate, ensuring the good conductivity of the annular conductive substrate. It is convenient and practical.

[0017] (2) The charge released by the annular electrode can be conducted through the annular conductive substrate to generate static electricity. When the liquid sprayed from the nozzle encounters the applied static electricity, the crops can be sprayed with static electricity. The circular ring can connect the L-shaped rod and the insulating cover to facilitate the rotation of the L-shaped rod. The elastic rubber block will abut the insulating cover under elasticity to fix the rotated L-shaped rod. BRIEF DESCRIPTION OF THE DRAWINGS

The nozzle body 1 is an existing nozzle for spraying medicine, and its internal structure and principle have been disclosed, so no further elaboration is given here.

A plurality of connecting rods 11 are fixed between the outer wall of the nozzle body 1 and one side of the insulating cover 3. The connecting rods 11 can connect the nozzle body 1 and the insulating cover 3. The annular conductive substrate 31 can conduct the charge released by the annular electrode 2 and generate static electricity. After the liquid sprayed from the nozzle body 1 encounters the applied static electricity, it can perform electrostatic spraying on crops. The insulating cover 3 is annular and can be made of insulating materials such as ceramics.

[0026] See also Figure 1-3 A first annular groove 32 is provided on the inner side of the insulating cover 3, the annular electrode 2 is fixedly arranged on the inner side of the first annular groove 32, and the annular conductive substrate 31 is fixedly arranged on the opening side of the first annular groove 32. The outer wall of the annular conductive substrate 31 is in contact with the inner wall of the annular electrode 2, so that the annular electrode 2 is covered between the insulating cover 3 and the annular conductive substrate 31, so that the annular electrode 2 will not directly contact with the external drug solution.

[0027] See also Figure 2-3 A scraping mechanism is provided in the insulating cover 3, and the scraping mechanism includes an L-shaped rod 4 rotatably arranged in the insulating cover 3, and an insulating scraper 41 fixedly arranged at one end of the L-shaped rod 4 for scraping off scale on the annular conductive substrate 31. When in use, the drug liquid will contact the annular conductive substrate 31. After long-term use, the drug liquid will form scale on the annular conductive substrate 31. People can rotate the L-shaped rod 4 to drive the insulating scraper 41 to rotate to scrape off the scale on the annular conductive substrate 31, thereby ensuring good conductive performance of the annular conductive substrate 31. The insulating scraper 41 can be made of a material with insulating effect such as hard rubber.

[0028] See also Figure 2-4 A second annular groove 33 is provided on the inner side of the insulating cover 3, and a circular ring 42 is rotatably connected in the second annular groove 33 of the insulating cover 3. The L-shaped rod 4 is fixed on the inner wall of the circular ring 42. The insulating cover 3 can be connected to the circular ring 42 through the second annular groove 33.

When the force used to rotate the L-shaped rod 4 is greater than the abutting pressure of the elastic rubber block 43 on the insulating cover 3, the L-shaped rod 4 can still rotate, which is convenient for operation.

[0030] See also Figure 2-4An insulating sleeve 44 for people to hold is fixedly provided on the outer wall of one end of the L-shaped rod 4 away from the insulating scraper 41. The outer wall of the insulating sleeve 44 is provided with anti-slip grooves 45. The insulating sleeve 44 can be made of a material with insulating effect such as rubber. People can hold the insulating sleeve 44 to drive the L-shaped rod 4 to rotate. The anti-slip grooves 45 can reduce the chance of people's hands slipping when holding the insulating sleeve 44.

[0031] Working principle: When in use, the annular conductive substrate 31 can conduct the charge released by the annular electrode 2 and generate static electricity. After the liquid medicine sprayed by the nozzle body 1 encounters the applied static electricity, it can perform electrostatic spraying on crops. Since the insulating cover 3 and the annular conductive substrate 31 can provide waterproof protection for the annular electrode 2, the annular electrode 2 will not directly contact the liquid medicine, thereby avoiding corrosion by the liquid medicine water, and extending the service life of the annular electrode 2;

[0032] People can hold the insulating sleeve 44 to drive the L-shaped rod 4 to rotate, thereby driving the insulating scraper 41 and the ring 42 and other components to rotate. After the insulating scraper 41 rotates, it will scrape off the scale on the annular conductive substrate 31 to ensure the good conductive performance of the annular conductive substrate 31.
