[0046] like Figures 1 to 10 As shown, according to an embodiment of the present invention, a spray head 20 is proposed, which includes a tube body 21 and a spray assembly 22. One end of the tube body 21 is used to communicate with the body 10 of the pesticide spray equipment 100, and a spray assembly 22 is provided at the other end of the tube body 21. The tube body 21 is located on the main body between the two ends and at least one spray assembly 22 is provided. The spray assembly 22 includes a connecting seat 221 and a nozzle 222. The connecting seat 221 is connected to the tube body 21. The connecting seat 221 has a connecting channel 2211 communicating with the tube body 21. The nozzle 222 is detachably arranged on the connecting seat 221 and is connected to the connecting channel 2211. The nozzle 222 includes a spray hole, and the nozzle 222 can be rotated relative to the connecting seat 221 to adjust the spray direction of the spray hole.

[0047] According to the nozzle 20 of the present invention, when using the nozzle 20, one end of the tube 21 of the nozzle 20 is connected to the body 10 of the pesticide spraying device 100. When spraying pesticides, the pesticides in the body 10 enter the tube 21, and the pesticides in the tube 21 are sprayed through the connection channel 2211 of the connection seat 221 and the nozzle 222. During the process of spraying pesticides, the spray assembly 22 located at the other end of the tube 21 can spray the pesticides on the stems of the plants through the leaves. The spray assembly 22 located between the two ends of the tube 21 can spray the pesticides on the leaves of the plants, thereby achieving the operation of spraying the pesticides on the leaves and stems of the plants at the same time, thereby achieving the purpose of eradicating pests and diseases.

[0048] It should be understood that by providing multiple spray assemblies 22, pesticides can be sprayed on the leaves and stems of plants respectively, thereby reducing the amount of pesticides used and the pesticide costs of users. At the same time, it also reduces the occurrence of plant damage caused by excessive use of pesticides.

[0049] In the present application, the connection between the nozzle 222 and the connecting seat 221 is detachable, and nozzles 222 of different specifications can be replaced by detachment to meet different spraying needs.

[0050] In addition, the nozzle 222 can be rotated relative to the connecting seat 221. By rotating the angle of the nozzle 222, the spraying direction of the spray hole can be adjusted, which can further meet the spraying needs.

[0051] It should be noted that the connection base 221 is connected and fixed to the tube body 21, and the connection channel 2211 in the connection base 221 is connected to the interior of the tube body 21. The connection between the connection base 221 and the tube body 21 includes but is not limited to welding, bonding or screwing.

[0052] In addition, one end of the tube body 21 is used to communicate with the body 10 of the pesticide spraying equipment 100, wherein the body 10 includes a medicine box, the medicine box has a connecting pipe, and one end of the tube body 21 is connected to the connecting pipe through a connecting member 30, and the connecting member 30 can be a component such as a plug-in joint.

[0053] In some embodiments of the present invention, Figure 5 、 Figure 6 and Figure 10 As shown, the nozzle 222 assembly also includes a limiting member 223. Part of the nozzle 222 is arranged in the connecting channel 2211. The limiting member 223 is connected to the connecting seat 221 in a detachable manner. The limiting member 223 cooperates with the nozzle 222 to limit the component nozzle 222 to the connecting channel 2211.

[0054] Specifically, the limiting member 223 is detachably connected to the connecting seat 221. When the nozzle 222 needs to be replaced, the cooperation between the limiting member 223 and the nozzle 222 is released, so that the nozzle 222 can be taken out from the connecting channel 2211 to realize the replacement of the nozzle 222. After the nozzle 222 is replaced, the limiting member 223 can be matched with the nozzle 222.

[0055] In addition, when it is necessary to adjust the spray direction of the nozzle hole on the nozzle 222, the contact limiter 223 cooperates with the nozzle 222 to drive the nozzle 222 to rotate relative to the connecting seat 221, thereby adjusting the spray direction of the nozzle 222. After the adjustment is completed, the limiter 223 can be matched with the nozzle 222.

[0056] In some embodiments of the present invention, Figure 5 、 Figure 6 and Figure 10 As shown, the limiting member 223 includes a cylindrical portion 2231 and a flange portion 2232. The cylindrical portion 2231 is threadedly connected to the outer peripheral surface of the connecting seat 221. The flange portion 2232 is arranged at one end of the cylindrical portion 2231 and protrudes radially inward of the cylindrical portion 2231. The flange portion 2232 and the nozzle 222 form a limit.

[0057] Specifically, when the limiting member 223 cooperates with the connecting seat 221, the cylindrical portion 2231 is sleeved on the outside of the connecting seat 221 and is threadedly connected to the outer peripheral surface of the connecting seat 221. When the threaded connection is in place, the flange portion 2232 forms a limit on the nozzle 222 arranged in the connecting channel 2211, so that the nozzle 222 cannot escape through the opening position of the connecting channel 2211, thereby realizing the installation of the nozzle 222.

[0058] It should be understood that the structure formed by the cylindrical portion 2231 and the flange portion 2232 is a locking structure at one end (the side with the flange), and the locking structure is used to limit the nozzle 222, thereby facilitating operation during use and improving convenience during use.

[0059] It should be noted that in other embodiments of the present application, the limiting member 223 may also be an elastic hook or the like.

[0060] In some embodiments of the present invention, Figure 5 、 Figure 6 and Figure 9As shown, the nozzle 20 includes a cylindrical body 2221 and a protruding structure 2222. The cylindrical body 2221 is arranged in the connecting channel 2211. The end of the cylindrical body 2221 facing the outside of the connecting channel 2211 is a closed structure. Along the axial direction of the cylindrical portion 2231, the flange portion 2232 forms a limit for the respective structures. The protruding structure 2222 is arranged on the closed structure. Along the axial direction of the cylindrical portion 2231, the protruding structure 2222 protrudes on the side of the flange portion 2232 away from the connecting channel 2211. The spray hole is opened on the protruding structure 2222 and passes through the closed structure.

[0061] Specifically, the protruding structure 2222 is arranged to protrude relative to the flange portion 2232 of the stopper 223. When the angle of the spray hole needs to be adjusted, the connection between the cylindrical portion 2231 and the connecting seat 221 is loosened, so that the flange portion 2232 is separated from the cylindrical body 2221. At this time, the nozzle 222 can be rotated relative to the connecting seat 221 by manipulating the protruding structure 2222. After the position of the spray hole is adjusted, the cylindrical portion 2231 is tightened. This arrangement allows the spray hole angle to be adjusted without separating the stopper 223, further improving convenience during use.

[0062] It should be noted that the number of the spray holes formed on the protruding structure 2222 can be one, two, three or four.

[0063] In the present application, the raised structure 2222 is a rectangular structure, and the number of the spray hole is one, which is a rectangular hole opened on the raised structure 2222. The spray hole is set as a rectangular hole so that the pesticide can be sprayed out of the spray hole in a fan-shaped structure, thereby increasing the spraying range and improving the spraying efficiency.

[0064] In some embodiments of the present invention, Figure 5 、 Figure 6 and Figure 7 As shown, the spray assembly 22 further includes a filter 224 . The filter 224 is disposed on a side of the cylindrical body 2221 away from the protruding structure 2222 and is used to filter the fluid entering the cylindrical body 2221 .

[0065] By providing the filter element 224 , the fluid entering the nozzle 222 can be filtered, thereby reducing the occurrence of clogging of the nozzle 222 and reducing the occurrence of the spraying operation being unable to proceed normally due to the clogging of the nozzle 222 .

[0066] It should be noted that the filter element 224 can be a filter plate or a filter mesh, etc.

[0067] In some embodiments of the present invention, Figure 5 、 Figure 6 and Figure 8 As shown, a shoulder structure 2212 is provided in the connecting channel 2211, the filter element 224 rests on the shoulder structure 2212, and the cylindrical body 2221 rests on the side of the filter element 224 facing away from the shoulder structure 2212. The shoulder structure 2212 is provided to limit the filter element 224, thereby ensuring the installation accuracy of the filter element 224 and improving the filtering effect on the fluid.

[0068] In some embodiments of the present invention, the spray assembly 22 further includes a seal, which is sealed between the flange 2232 and the nozzle 222. The seal can reduce leakage of fluid between the flange 2232 and the nozzle 222, thereby improving the spraying effect and reducing waste.

[0069] It should be noted that the sealing member may be a rubber ring or a silicone ring, etc.

[0070] In some embodiments of the present invention, Figure 2 、 Figure 3 and Figure 4 As shown, two spray assemblies 22 are provided on the main body of the tube body 21 between the two ends. The three spray assemblies 22 are spaced apart along the length direction of the tube body 21. Among the three spray assemblies 22, the distance between the spray assembly 22 in the middle and the spray assembly 22 at the other end of the tube body 21 is 8-15 cm (as shown in FIG. Figure 4 As shown, Figure 4 The distance between the spray assembly 22 located in the middle and the spray assembly 22 on the other side away from the tube body 21 is 5-10 cm (e.g. Figure 4 As shown, Figure 4 b size in ).

[0071] Specifically, in the present application, there are three spray assemblies 22, which are sequentially arranged along the length of the tube body 21. One end of the tube body 21 is used to communicate with the body 10 of the pesticide sprayer 100. The first spray assembly 22 is arranged on the other end of the tube body 21, the second spray assembly 22 is arranged between the two ends of the tube body 21, and the third spray assembly 22 is also arranged between the two ends of the tube body 21. The third spray assembly 22 is spaced apart on the side of the second spray assembly 22 facing away from the first spray assembly 22. By providing three spray assemblies 22, the spraying range can be increased, and the spraying efficiency is effectively improved.

[0072] In addition, the distance between the first spray assembly 22 and the second spray assembly 22 is 8-15 cm, and the distance between the second spray assembly 22 and the third spray assembly 22 is 5-10 cm. By setting the distance between the three spray assemblies 22, the three spray assemblies 22 can have a sufficient distance from each other, thereby reducing the intersection between each other, and thus improving the uniformity of the pesticide after spraying.

[0073] It should be pointed out that, in the present application, the spraying directions of the three spray assemblies 22 are all located on the same side of the tube body 21 .

[0074] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the tube body 21 includes a bend 211. Of the three spray assemblies 22, the spray assembly 22 located in the middle and the spray assembly 22 located at the other end of the tube body 21 are respectively arranged on opposite sides of the bend 211. By providing the bend 211, during use, the spray assembly 22 connected to the other end of the tube body 21 can bypass interference factors of the plant through the bend 211, thereby effectively spraying the stems of the plant.

[0075] like Figures 1 to 10 As shown, the second aspect of the present application provides a pesticide spraying device 100 , which includes a body 10 and a nozzle 20 as described above, wherein one end of a tube 21 of the nozzle 20 is connected to the body 10 .

When spraying pesticides, the pesticides in the body 10 enter the tube body 21, and the pesticides in the tube body 21 are sprayed through the connecting channel 2211 of the connecting seat 221 and the nozzle 222. During the process of spraying pesticides, the spray assembly 22 located at the other end of the tube body 21 can spray pesticides on the stems of plants through the leaves. The spray assembly 22 located between the two ends of the tube body 21 can spray pesticides on the leaves of plants, thereby realizing the operation of spraying pesticides on the leaves and stems of plants at the same time, thereby achieving the purpose of eradicating pests and diseases.

[0077] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
