Description

Technical Field

[0001] The utility model relates to the technical field of sprayers, in particular to a heat dissipation back pad for a sprayer. Background Art

[0002] In agricultural production, with the advancement of science and technology, electric sprayers are widely used in plant protection operations, that is, spraying or fertilizing crops. Users usually carry the electric sprayer on their backs during the spraying or fertilizing process. The back pad of the sprayer contacts the user's back. When the weather is hot, the overall air permeability of the back pad is poor. The existing sprayer back pad only serves as a buffer and a comfortable carrying effect, and cannot cope with the problem of stuffiness caused by hot weather. When the user sprays or fertilizes for a long time, a lot of sweat will flow out of the back, causing the clothes to stick to the body and causing discomfort.

[0003] At present, the heat dissipation of existing electric sprayers is mostly achieved through their own heat dissipation.

[0004] Therefore, a sprayer heat dissipation back pad is needed to improve the above problems. Utility Model Content

[0007] A heat dissipation back pad for a sprayer, a back pad main body, a groove is provided on the back of the back pad main body, docking structures are provided at the upper and lower ends of the back pad main body, a fan is installed in the middle of the groove, the fan is connected to a control switch through a wire, and the control switch is electrically connected to a battery, a plurality of air outlet slots are provided in the middle of the front of the back pad main body at the position corresponding to the fan, a raised ventilation structure is provided on the front of the back pad main body, and ventilation gaps are formed between the raised ventilation structures to dissipate heat.

[0008] As a preferred solution of the utility model, the fan is fixedly connected to the back pad body by bolts.

[0009] As a preferred solution of the utility model, the raised ventilation structure includes a plurality of protrusions, and a plurality of grooves are evenly spaced at the connection between each protrusion and the back pad body.

[0010] As a preferred solution of the utility model, the convex blocks include regular hexagons and irregular hexagons, and adjacent convex blocks are arranged at intervals.

[0011] As a preferred solution of the utility model, a plurality of strip grooves are formed through the side of the back pad body at equal intervals, and a plurality of inwardly recessed reinforcement grooves are provided on both sides of the back pad body.

[0012] As a preferred solution of the utility model, the docking structure includes an upper connecting frame and a lower connecting frame.

[0013] As a preferred solution of the utility model, the upper end of the upper connecting frame is provided with convex ends on both sides, and the convex ends on both sides are provided with docking grooves, and the lower end of the lower connecting frame is provided with a convex column for docking with the sprayer box.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model arranges an electrically controlled fan and a raised ventilation structure in the back pad body, and the two are arranged in coordination. When spraying medicine and fertilizing, the fan accelerates the air flow, and the raised ventilation mechanism reduces the contact area between the back pad and the user's back, so as to facilitate heat dissipation, avoid excessive sweating of the user, maintain physical comfort, achieve a cooling effect, and improve the comfort of use of the sprayer.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively below with reference to the relevant. Several embodiments of the utility model are given. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] See also Figure 1-4 , the utility model provides a technical solution:

[0026] For example, please refer to Figure 1 , 2 , 3 and 4, a sprayer heat dissipation back pad, including a back pad main body 1, a groove is provided on the back of the back pad main body 1, and docking structures are provided at the upper and lower ends of the back pad main body 1. A fan 8 is installed in the middle of the groove, and the fan 8 is fixedly connected to the back pad main body 1 by bolts. The fan 8 is connected to a control switch 9 through a wire, and the control switch 9 is electrically connected to a battery 10. A plurality of air outlet slots 6 are provided in the middle of the front of the back pad main body 1 corresponding to the position of the fan 8, and a raised ventilation structure is provided on the front of the back pad main body 1, and ventilation gaps are formed between the raised ventilation structures to dissipate heat.

[0027] The fan 8 is connected to the battery 10 and is conveniently controlled by the control switch 9. It is easy to use. When in use, the setting of the raised ventilation structure can reduce the contact area with the user's back, making it easier to dissipate heat. At the same time, the fan 8 accelerates the flow of air to achieve rapid heat dissipation and rapid cooling.

[0028] Please refer to Figure 1 , 2, 3 and 4, the raised ventilation structure includes a plurality of protrusions 3, and a plurality of slots 11 are evenly spaced at the connection between each protrusion 3 and the back pad body 1, the protrusion 3 includes a regular hexagon and an irregular hexagon, and adjacent protrusions 3 are spaced apart.

[0029] The arrangement of the slots 11 facilitates the wind from the fan 8 to blow air to the contact point between the user's back and the protrusion 3, resulting in better ventilation effect. The irregular hexagonal arrangement of the protrusion 3 has a longer overall length, thus avoiding discomfort caused by contact with the user's back.

[0030] Please refer to Figure 1 , 2 , 3 and 4, a plurality of strip grooves 4 are formed at equal intervals through the side of the back pad body 1, a plurality of inwardly recessed reinforcing grooves are formed on both sides of the back pad body 1, the docking structure comprises an upper connecting frame 2 and a lower connecting frame 7, convex ends are formed on both sides of the upper end of the upper connecting frame 2, docking grooves 5 are formed on the convex ends on both sides, and a convex column for docking with the sprayer box is formed at the lower end of the lower connecting frame 7.

[0031] The strip grooves 4 can facilitate the dissipation of internal heat. The upper connecting frame 2 and the lower connecting frame 7 are used to connect to the sprayer box to install the entire back pad body 1.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
