Description

Technical Field

[0001] This application relates to the field of backpack spray gun technology, and more specifically, to a positioning waterproof backpack spray gun. Background Technology

[0002] In daily life, backpack sprayers are the most widely used type of powered plant protection machinery, mainly used for large-scale pest and disease control, and also commonly used as a tool for hygiene, epidemic prevention and disinfection.

[0003] Existing backpack spray cans require the installation of GPS chips and other components to determine the operator's location and ensure the accuracy of the spraying trajectory. However, current technologies offer poor waterproofing for GPS chips mounted on the outside of the spray can, primarily because the can itself sprays material and is exposed to a humid environment for extended periods. Furthermore, the waterproofing of the GPS chip cannot be guaranteed during rainy weather, making the installation of GPS chips relatively costly and difficult. Utility Model Content

[0032] Reference Figure 1-5 ,

[0033] A waterproof backpack spray can includes a spray can 1, a water pump 2, a spray gun 3, and a waterproof component 4. The spray can 1 is the main body, the water pump 2 is installed on the upper end of the spray can 1, and the water intake end of the water pump 2 is located inside the spray can 1. The output end of the water pump 2 is connected to the spray gun 3. The spray gun 3 is snapped onto one side of the spray can 1, and the spray gun 3 is equipped with a switch to control the start and stop of the water pump 2, so as to control the water pump 2 to deliver the spray material from the spray can 1 to the spray gun 3. The waterproof component 4 is installed at one end of the spray can 1, and a GPS chip is placed inside the waterproof component 4 to provide real-time positioning of the spray can 1.

[0034] Specifically, a carrying strap 11 is provided on one side of the spray barrel 1, and the carrying strap 11 is fixedly connected to the wall of the spray barrel 1. The carrying strap 11 is used for carrying the operator. A feed inlet 12 is provided on one side of the upper end of the spray barrel 1, and the feed inlet 12 is connected to the inner cavity of the spray barrel 1. A drain outlet 13 is provided on the other side of the upper end of the spray barrel 1, and the drain outlet 13 is connected to the inner cavity of the spray barrel 1. The drain outlet 13 is detachably connected to the water pump 2, so that the water pump 2's pumping end passes through the drain outlet 13 and enters the inner cavity of the spray barrel 1. A buckle 14 is provided on the side end of the spray barrel 1. The locking diameter of the buckle 14 matches the rod of the spray gun 3. The buckle 14 is made of elastic material, and the inlet diameter of the buckle 14 is smaller than that of the spray gun 3 rod, so that the rod of the spray gun 3 enters the buckle through the inlet of the buckle 14 and is limited. In this embodiment, there are two clips 14, one above the other, to secure the upper and lower ends of the spray gun 3 to ensure the stability of the spray gun 3.

[0035] Specifically, the waterproof component 4 is installed at the end of the spray can 1 away from the shoulder strap 11. The waterproof component 4 is made entirely of waterproof material and includes a waterproof outer shell 41, a sealing plate 42, a partition 43, and a rebound rod 44. The waterproof outer shell 41 is fixedly installed on the outer wall of the spray can 1. The waterproof outer shell 41 has a chamber, and an opening is provided at the end of the waterproof outer shell 41 away from the wall of the spray can 1. This opening matches the outer periphery of the sealing plate 42, thus sealing the opening of the waterproof outer shell 41. The sealing plate 42 is embedded within the waterproof outer shell 41 and is slidably connected to the chamber within the waterproof outer shell 41. A pull rod 421 is provided on the outer wall of the sealing plate 42, and the pull rod 421 is connected to a fixed wheel on the outer wall of the sealing plate 42. The pull rod 421 provides space for manual operation. A sealing strip 422 is fitted onto the outer periphery of the sealing plate 42 to ensure a sealed contact when the sealing plate 42 enters the chamber of the waterproof outer shell 41. A mounting box 423 is provided on the inner wall of the sealing plate 42 relative to the pull rod 421. The mounting box 423 has a cavity for placing the GPS chip, so that the GPS chip is placed in the cavity with a limiting position. The upper end of the mounting box 423 has a placement opening, and a cover 424 is detachably connected to the placement opening. The cover 424 matches the placement opening so that the cover 424 seals the GPS chip after it is placed in the cavity to ensure waterproofness. The partition 43 is installed in the cavity of the waterproof shell 41, and the partition 43 is installed on the inner side relative to the sealing plate 42. The partition 43 is fixedly connected to the perimeter wall of the cavity of the waterproof shell 41, and through holes are provided around the partition 43 for the rebound rod 44 to pass through. The partition 43 forms a rebound cavity 431 and a placement cavity 432 in the cavity of the waterproof shell 41, respectively. The rebound cavity 431 is close to the wall of the spray barrel 1, and the placement cavity 432 is close to the opening end of the waterproof shell 41. Multiple rebound rods 44 are provided, and each rebound rod 44 passes through the through holes around the partition 43 and is embedded in the cavity of the waterproof shell 41. One end of the rebound rod 44 abuts against the wall of the spray tank 1, and the other end of the rebound rod 44 is fixedly connected to the sealing plate 42. A limiting piece 441 is provided at the end of the rebound rod 44 that abuts against the wall of the spray tank 1. The diameter of the limiting piece 441 is larger than the diameter of the through hole of the partition 43. The rebound rod 44 is slidably connected to the partition 43 so that the limiting piece 441 limits the rebound rod 44 when it slides. Springs 442 are fitted around the outer periphery of the rebound rod 44 and inside the rebound cavity 431. One end of the spring 442 is fixedly connected to the limiting piece 441, and the other end of the spring 442 abuts against the wall of the partition plate 43. When the rebound rod 44 is pulled by the pull rod 421 outside the sealing plate 42, the rebound rod 44 moves and squeezes the spring 442 at the same time, so as to move the mounting box 423 from the placement cavity 432 to the outside of the waterproof shell 41, which facilitates the installation and removal of the GPS chip.

[0036] Working principle:

[0037] This waterproof backpack spray can protect the GPS chip from water using a waterproof assembly. The assembly consists of a waterproof housing and a sealing plate forming a sealed cavity, with the GPS chip housed in a mounting box inside the sealing plate. A partition divides the cavity into a rebound chamber and a placement chamber. One end of a rebound rod is fixed to the sealing plate, while the other end passes through the partition and abuts against the spray can wall. A spring is fitted onto the rebound rod. When the pull rod on the outside of the sealing plate is pulled, the rebound rod causes the sealing plate to slide outward, compressing the spring and removing the mounting box from the placement chamber, facilitating the installation or maintenance of the GPS chip. Releasing the pull rod causes the spring to return the sealing plate to its original position, and the sealing strip tightly abuts against the inner wall of the waterproof housing, forming a waterproof seal that protects the GPS chip from water damage in humid environments or rainy weather.
