Description

Technical Field

[0001] This technical solution relates to the technical field of sprayers, specifically referring to a spray wind shield. Background Art

[0002] A sprayer is the abbreviation of spray equipment. Its working principle is to use the siphon effect to convert liquid medicine or other liquids into a mist and evenly spray it onto the surface of an object. It mainly consists of components such as a compressed air device, a thin tube, a nozzle, and a wind shield.

[0003] As for the relevant wind shield structures disclosed in Chinese Patent CN202121070608.3 and Chinese Patent CN202430170981.9, the existing wind shields generally adopt a conical or frustum-shaped design, but there are still some deficiencies: the sprayed water mist is in a divergent state outward. The farther the distance, the larger the divergence area of the water mist, resulting in the inability to achieve precise spraying in a local area. For example, when spraying pesticides in an agricultural scenario, the divergent water mist is extremely likely to drift onto adjacent crops, thus having an adverse impact on the growth of other crops. In severe cases, it may even cause the death of the crops. Summary of the Utility Model

[0004] The purpose of this technical solution is to provide a spray wind shield. By installing a guiding ring at the end of the wind shield body, the side wall of the guiding ring is parallel to the axis of the wind shield body, thereby avoiding the radial diffusion of the water mist during spraying and improving the problem that the existing wind shield cannot directionally restrict the water mist and thus cannot achieve precise spraying in a local area.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A spray wind shield for installing on the nozzle of a sprayer, comprising:

[0007] A wind shield body, which is frustum-shaped and has a channel for spraying water mist inside. The side wall of the channel is inclined such that the diameter of the front end of the channel is larger than that of the rear end.

[0008] A guiding ring, which is installed at the front end of the wind shield body and is in communication with the channel. The side wall of the guiding ring is parallel to the axis of the wind shield body.

[0009] Preferably, the axis of the guiding ring coincides with the axis of the wind shield body.

[0010] Preferably, a zipper assembly or a Velcro assembly is provided between the front end of the wind shield body and the rear end of the guiding ring for detachably installing the guiding ring on the wind shield body.

[0011] Preferably, the guiding ring is connected with a connecting belt, and the end of the connecting belt is wound around the windshield body, so as to install the guiding ring on the windshield body.

[0012] Preferably, the front end of the windshield body has a first installation part, and the rear end of the guiding ring has a second installation part. The first installation part and the second installation part are connected together by threads, adhesives or sewing.

[0013] Preferably, the guiding ring is made of canvas material or plastic.

[0014] Preferably, the guiding ring is a foldable structure, and a folding part is provided in the middle thereof. By deforming the folding part of the guiding ring, the distance between the two ends of the guiding ring can be adjusted.

[0015] Preferably, a counterweight is arranged at the front end of the guiding ring to keep the shape of the guiding ring.

[0016] Preferably, the diameter of the channel increases in a stepped manner in the axial direction of its axis.

[0017] Preferably, a connecting part is arranged at the rear end of the channel, a connecting hole is arranged in the center of the connecting part, and a threaded part is arranged on the inner wall of the connecting hole for connecting to the nozzle of the sprayer.

[0018] The prominent and beneficial technical effects of this technical solution compared with the prior art are:

[0019] This technical solution is designed to install a guiding ring at the end of the windshield body. The side wall of the guiding ring is parallel to the axis of the windshield body, which radially restricts the water mist sprayed out of the windshield body, thereby avoiding the radial diffusion of the water mist during spraying, ensuring that the water mist is accurately sprayed along the predetermined direction of the guiding ring, realizing the directional spraying of the target area, and improving the accuracy of spraying in the local area.

Detailed implementation manners

[0028] The following further elaborates on the detailed implementation manners of the present technical solution in conjunction with the accompanying drawings. Refer to Figures 1-7 .

[0029] For the first embodiment, refer to Figures 1-5 :

[0030] A spray windproof cover, which is used to be installed on the nozzle of a sprayer to radially restrict the sprayed water mist and ensure the accuracy and stability during spraying on a local area. It includes:

[0031] A windproof cover body 1, which is in a frustum shape or a conical structure, and a channel 11 for water mist spraying or movement is provided therein. The side wall of the channel 11 is inclined such that the diameter of the front end of the channel 11 is larger than that of the rear end, so that the shape of the channel 11 is a frustum shape or a conical structure; and

[0032] A guiding ring 2, which is installed at the front end of the windproof cover body 1 and communicates with the channel 11. The axis of the guiding ring 2 coincides with the axis of the windproof cover body 1, that is, the central axis (i.e., the central line) of the guiding ring 2 coincides with the central axis (central line) of the windproof cover body 1, so that the windproof cover body 1 and the guiding ring 2 are concentrically or coaxially arranged, and the straight line where the side wall of the guiding ring 2 is located is parallel to the axis of the windproof cover body 1 (i.e., the center line or central axis of the windproof cover body 1).

[0033] The guiding ring 2 is in a columnar structure. The side wall of the guiding ring 2 is parallel to the central axis of the guiding ring 2, and the side wall of the guiding ring 2 is parallel to the central axis of the windproof cover body 1. Specifically, the side wall of the guiding ring 2 is parallel to the central axis of the opening at the front end of the channel 11 in the windproof cover body 1, so as to radially restrict the water mist sprayed out in the channel 11 of the windproof cover body 1 and prevent the water mist from diffusing by moving along the side wall of the channel 11. By guiding and restricting the front end of the channel 11 through the guiding ring 2, the movement trajectory of the water mist can be restricted by the guiding ring 2, thereby ensuring the operation of directional spraying on a directional area and ensuring the accuracy of the spraying area. In addition, the central axis of the guiding ring 2 coincides with the center line of the opening at the front end of the channel 11.

[0034] The front end of the windshield body 1 has a first mounting portion 12, and the rear end of the guide ring 2 has a second mounting portion 21. The rear end of the guide ring 2 is inserted into the front end of the channel 11, and the first mounting portion 12 and the second mounting portion 21 are connected to each other. The first mounting portion 12 and the second mounting portion 21 are connected by screw connection or adhesive connection (i.e., glue pasting connection) or sewing connection, or a plurality of screws or pins or bolts are circumferentially distributed on the front edge of the front end of the windshield body 1, and the guide ring 2 is mounted on the windshield body 1 by passing the screws or pins or bolts through the first mounting portion 12 and the second mounting portion 21.

[0035] The guide ring 2 is made of canvas material or plastic.

[0036] The guide ring 2 is made of nylon cloth or polyester cloth or coated cloth (such as PVC coated cloth, silicone coated cloth) or PP material or PE material or PVC material.

[0037] A weight 3 is provided at the front end of the guide ring 2, that is, a weight 3 is provided at the end of the guide ring 2 away from the windshield body 1, which is used to keep the guide ring 2 able to maintain the shape in the unfolded state, ensuring the radial constraint of the guide ring 2 on the water mist;

[0038] Such as Figure 3 , the weight 3 is a weight ring, the weight ring is concentrically arranged with the guide ring 2, and the weight ring is arranged at the lower edge of the guide ring 2. The lower edge of the guide ring 2 is bent to form a fixing groove, the notch of the fixing groove faces the rear end of the guide ring 2, and the weight ring is installed and fixed in the fixing groove, and the weight ring is wrapped and fixed by the fixing groove, or the fixing groove and the weight ring are fixed by interference fit, or the weight ring is fixed to the lower edge of the guide ring 2 by adhesive or sewing.

[0039] Or, combined with Figure 5 , the weight 3 is a plurality of weight blocks, which are circumferentially distributed on the lower edge of the guide ring 2, and the weight blocks can be suspended on the lower edge of the guide ring 2 by ropes or installed and fixed by the installation method of the weight ring in the above text.

[0040] The guide ring 2 is a foldable structure, thereby reducing the storage space and facilitating storage. Correspondingly, the material of the guide ring 2 is a deformable material (such as canvas material). The middle part of the guide ring 2 has a folding part 22, and the folding part 22 is wavy. By deforming the folding part 22 of the guide ring 2, the distance between the two ends of the guide ring 2 is adjusted, that is, the front end and the rear end of the guide ring 2 are brought closer to realize folding and contraction.

[0041] The diameter of the channel 11 increases step by step in the axial direction, that is, the diameter of the channel 11 increases step by step in the direction close to its front end; the diameter of the part closest to the installation of the guide ring 2 is the largest.

[0042] The diameter of the wind shield body 1 increases step by step in its axial direction, that is, the diameter of the outer side wall of the wind shield body 1 increases step by step in the direction close to its front end.

[0043] The inner wall of the rear end of the channel 11 contracts inward to form a connecting part 13. A connecting hole 14 is arranged at the center of the connecting part 13, and a threaded part 141 is arranged on the inner wall of the connecting hole 14. The threaded part 141 is used for connecting to the nozzle of the sprayer.

[0044] Embodiment Two:

[0045] The design scheme of this embodiment is basically the same as that of Embodiment One, and the difference lies in:

[0046] As Figure 6 and Figure 7 shown, a zipper assembly is arranged between the front end of the wind shield body 1 and the rear end of the guiding ring 2, which is used to realize the detachable installation of the guiding ring 2 on the wind shield body 1.

[0047] The specific structure of the zipper assembly refers to that described in Chinese Patent CN201721180305.0. A first chain belt 41 is circumferentially arranged on the front edge of the wind shield body 1 or the first chain belt 41 is installed on the outer side of the first mounting part 12. A second chain belt 42 is circumferentially arranged on the rear edge of the guiding ring 2 or the second chain belt 42 is installed on the outer side of the second mounting part 21. And the first chain belt 41 and the second chain belt 42 are provided with chain teeth or chain links, and a zipper head or a pull head is connected between the first chain belt 41 and the second chain belt 42.

[0048] Embodiment Three:

[0049] The design scheme of this embodiment is basically the same as that of Embodiment One or Embodiment Two, and the difference lies in:

[0050] A magic tape assembly is arranged between the front end of the wind shield body 1 and the rear end of the guiding ring 2, which is used to realize the detachable installation of the guiding ring 2 on the wind shield body 1.

[0051] The magic tape assembly is a prior art. Specifically, refer to Chinese Patent CN202320857983.5.
