Description

Technical Field

[0001] This utility model relates to the field of pest control equipment, and in particular to a spraying device for pest control. Background Technology

[0002] In pest control operations, spraying devices typically use bottled pesticides, which are injected into the sprayer manually by pouring or squeezing the bottle. Existing bottle cap and nozzle designs have significant flaws, causing pesticide residue to easily adhere to the inner wall of the cap, the threads of the nozzle, or the handle during actual use, thus contaminating the user's hands and affecting operational safety and convenience. Specifically, traditional cap structures usually employ a simple screw seal, lacking a flow guide design at the nozzle edge. This causes the pesticide to easily overflow and remain when poured. Furthermore, when opening the handle (such as common flip-top or pull-top caps), residual pesticide can easily adhere to the inside of the handle due to capillary action or surface tension. When the user closes the handle again or touches it, the pesticide will transfer to their hands, resulting in waste and potentially causing skin irritation or other safety hazards due to contact with high concentrations of pesticides.

[0003] Therefore, a spraying device for pest control was designed. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a spraying device for pest control. It solves the problem of defects in the bottle cap design of existing pest control agents, which easily leave a large amount of liquid residue on the bottle neck threads and cap handle when pouring, causing hand contamination for users. This not only wastes the agent but may also cause skin irritation, affecting the safety and convenience of operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spraying device for pest control includes a spray box, a spray pipe installed at the bottom of the spray box, a shoulder strap located on one side of the spray box, a feed inlet located at the top of the spray box, a flow guide plug located inside the feed inlet, and a sealing cap snapped into the flow guide plug.

[0007] Preferably, the flow guide plug is located inside the feed inlet and is fixedly connected to its inner wall, and the flow guide plug is annular in shape.

[0008] Preferably, the flow guide plug has an arc-shaped tube inside, an opening on one side of the arc-shaped tube, and the side of the flow guide plug is arc-shaped.

[0009] Preferably, the flow guide plug and the arc-shaped tube are integrally formed and the bottom is a downwardly convex arc surface.

[0010] Preferably, the bottom arc surface is provided with multiple guide channels, which are arranged in a ring array. The ends of the guide channels extend to the inner wall of the feed inlet, so that the residual liquid flows directly into the spray box.

[0011] Preferably, a plurality of protrusions arranged in a circumferential array are fixedly provided on the side wall of the sealing cover, and a sealing plug is fixedly provided at the bottom of the sealing cover.

[0012] Preferably, the sealing plug is inserted into the annular gap between the guide plug and the arc-shaped tube, and is press-fitted with the inner walls of both. The sealing plug is made of rubber.

[0013] Preferably, a connecting ring is fixedly provided at the bottom of the sealing plug, and the cross-section of the connecting ring is a trapezoidal shape with a larger top and a smaller bottom to facilitate flow.

[0014] Preferably, the connection between the sealing plug and the connecting ring forms an angle, and the side of the sealing plug that contacts the guide plug is triangular. The triangular edge of the sealing plug forms a scraping structure with the inner wall of the guide plug to remove residual liquid and scrape the residual liquid on the inner wall of the guide plug into the guide groove.

[0015] Preferably, a handle is fixedly provided on the top of the sealing cover. The handle is made of rubber and is elastic, making it easy to hang.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention significantly improves the performance of pest control spraying devices through an innovative flow-guiding and sealing design. The one-piece molded structure of the flow guide plug and the multi-stage flow-guiding channels ensure smooth pouring of the pesticide solution without spillage. The triangular scraping edge and trapezoidal flow-guiding structure of the sealing cap effectively remove and guide residual pesticide solution, achieving a reduction in residual liquid throughout the "open-pour-close" process. The circumferential array of protrusions and the elastic pull handle design enhance sealing performance and ease of operation. Compared with traditional devices, this design completely solves the problem of pesticide adhesion and contamination. Its durable one-piece structure is particularly suitable for high-frequency use in the field, greatly improving the efficiency and safety of pest control operations. Attached Figure Description

[0029] Please see Figure 1-5A spraying device for pest control includes a spray box 1, a spray pipe 2 installed at the bottom of the spray box 1, a shoulder strap 3 set on one side of the spray box 1, an inlet 11 opened at the top of the spray box 1, a guide plug 4 set inside the inlet 11, and a sealing cap 5 snapped into the guide plug 4.

[0030] The guide plug 4 is located inside the feed inlet 11 and is fixedly connected to its inner wall. The guide plug 4 is in the shape of a ring. An arc-shaped tube 41 is provided inside the guide plug 4. An opening is provided on one side of the arc-shaped tube 41. The side of the guide plug 4 is arc-shaped. The guide plug 4 and the arc-shaped tube 41 are integrally formed and the bottom is an arc-shaped surface that convexes downward. Multiple guide grooves 42 are provided on the bottom arc-shaped surface. The multiple guide grooves 42 are arranged in a ring array. The end of the guide grooves 42 extends to the inner wall of the feed inlet 11, so that the residual liquid flows directly into the spray box 1.

[0031] Multiple protrusions arranged in a circular array are fixedly provided on the side wall of the sealing cap 5. A sealing plug 51 is fixedly provided at the bottom of the sealing cap 5. The sealing plug 51 is inserted into the annular gap between the guide plug 4 and the arc tube 41 and is interference-fitted with the inner wall of both. The sealing plug 51 is made of rubber. A connecting ring 52 is fixedly provided at the bottom of the sealing plug 51. The cross-section of the connecting ring 52 is a trapezoidal shape with a larger top and a smaller bottom to facilitate flow. An angle is formed at the connection between the sealing plug 51 and the connecting ring 52. The side of the sealing plug 51 that contacts the guide plug 4 is triangular.

A pull handle 53 is fixedly provided at the top of the sealing cap 5. The pull handle 53 is made of rubber and is elastic to facilitate hanging.

[0032] When the user opens the sealing cover 5 using the elastic pull handle 53, the triangular scraping edge of the sealing plug 51 automatically scrapes away residual medicine from the inner wall of the guide plug 4 as the opening action is performed; during the pouring process, the medicine first enters the guide channel through the opening of the arc-shaped tube 41, then flows along the raised arc-shaped structure at the bottom of the guide plug 4, and is evenly distributed through the annular array of guide grooves 42 to ensure that the medicine is smoothly injected into the spray box 1 without overflow; when the sealing cover 5 is closed, the rubber sealing plug 51, the guide plug 4, and the arc-shaped tube 41 form a With an interference fit, the trapezoidal structure of its connecting ring 52 guides any residual liquid to the guide channel 42. At the same time, the circumferential array of protrusions on the side wall of the sealing cap 5 enhances the sealing performance. This workflow achieves zero residue of the agent throughout the entire process from opening, pouring to closing through a collaborative mechanism of "dynamic scraping - multi-stage guidance - bidirectional sealing". Compared with existing technologies, it not only solves the problem of liquid adhesion and contamination, but its one-piece molded structure also improves the sealing reliability and ease of operation of the device, making it particularly suitable for the harsh operating environment of field disinfection operations.
