[0048] The surveyor can obtain information about his / her own location from the display screen 131, and can control different functions of the positioning device 1 through a number of buttons 132. In this embodiment, the positioning device 1 is preferably the same in function and structure as a common handheld GPS locator with only positioning function; since the above-mentioned handheld GPS locator is a common prior art, the positioning device 1 is not described in detail here, and the positioning device 1 is only briefly shown in the attached drawings.

[0049] When the multifunctional GPS locator is in a handheld state, the display screen 131 is located above the buttons 132 , and the surveyor's holding position on the body 11 is located on the side of the buttons 132 away from the display screen 131 .

[0050] The insect repellent device 2 includes a base 21 , a medicine bottle 22 and a spray assembly 23 .

[0051] The base 21 is in a rectangular parallelepiped structure as a whole. The base 21 is fixedly mounted on a side of the body 11 away from the operation panel 13 and is located at an end of the body 11 close to the display screen 131 .

[0052] The medicine bottle 22 is a cylindrical structure as a whole, and has an inner cavity for holding the insect repellent solution inside the medicine bottle 22. The mouth of the medicine bottle 22 is detachably connected to the base 21, and the medicine bottle 22 is located on the side of the body 11 away from the buttons 132 after being connected to the base 21. In this embodiment, the medicine bottle 22 and the base 21 are preferably detachably connected in a threaded connection. Since this is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0053] The spray assembly 23 includes a plurality of nozzles 231, a liquid outlet pipe 232, and a pressing member 233. In this embodiment, the spray assembly 23 preferably includes two nozzles 231; in other embodiments, the number of the nozzles 231 may be greater.

[0054] Reference Figure 2 and Figure 3 The base 21 has a plurality of liquid outlet channels 211 inside, and the plurality of liquid outlet channels 211 correspond to the plurality of nozzles 231 one by one. Therefore, in this embodiment, it is preferred that the base 21 has two liquid outlet channels 211 in total.

[0055] One end of the two liquid outlet channels 211 forms openings at both sides of the length direction of the base 21 , and the other ends of the two liquid outlet channels 211 merge to form an opening at one end of the base 21 close to the medicine bottle 22 .

[0056] One end of the liquid outlet pipe 232 is fixedly connected to the base 21, the length direction of the liquid outlet pipe 232 is parallel to the length direction of the body 11, and one end thereof is connected to one end after the two liquid outlet channels 211 merge; after the medicine bottle 22 is connected to the base 21, the liquid outlet pipe 232 is located in the inner cavity, and the end of the liquid outlet pipe 232 away from the base 21 is close to the bottom of the inner cavity.

[0057] The two nozzles 231 are respectively fixedly mounted at both ends of the length direction of the base 21, and the two nozzles 231 respectively block the openings of the two liquid outlet channels 211 away from the liquid outlet pipe 232, and the nozzles 231 have the effect of breaking up the liquid into atomized form. In this embodiment, since the nozzles 231 having the above-mentioned effects are common prior art, they are not described in detail here, and are only briefly shown in the drawings.

[0058] The pressing member 233 is movably mounted on one end of the base 21 away from the body 11. When the multifunctional GPS locator is in a handheld state, the pressing member 233 can drive the insect repellent in the medicine bottle 22 to be sprayed out in the form of mist through the liquid outlet pipe 232, the liquid outlet channel 211 and the nozzle 231 after being pressed. In this embodiment, the pressing member 233 is preferably rotatably connected to the base 21, the rotation axis of the pressing member 233 is parallel to the length direction of the base 21, and the pressing member 233 can rotate and return to the position to be pressed after being pressed, so that the surveyor can press it next time; the principle of the spray assembly 23 to achieve the above effect is preferably the Bernoulli principle. Since the sprayer using the Bernoulli principle is a common prior art, the spray assembly 23 is not described here, and it is only briefly represented in the accompanying drawings (the relevant structure of the pressing member 233 driving the insect repellent in the medicine bottle 22 into the liquid outlet pipe 232 is omitted).

[0059] Further, the spray direction of the nozzle 231 is preferably perpendicular to the length direction of the body 11, toward the direction of the base 21 away from the body 11, and inclined relative to the length direction of the base 21. In this embodiment, the spray direction of the nozzle 231 preferably forms an acute angle of 45° with the length direction of the base 21.

[0060] It can effectively expand the diffusion range of the insect repellent spray and improve the effect of the insect repellent spray in repelling mosquitoes; at the same time, it can help the sprayed insect repellent fall on the surveyors, so that the surveyors have the smell of repelling mosquitoes, thereby further reducing the probability of the surveyors being bitten by mosquitoes.

[0061] After the surveyor arrives at the designated location with the help of the positioning device 1, there is no need to continue holding the multifunctional GPS locator during the survey of the surrounding area. In order to enable the insect repellent device 2 to still have a certain effect of repelling mosquitoes during the survey of the surveyor, the insect repellent device 2 also includes a plurality of air permeable components 24 and a plurality of heating components 25. In this embodiment, the insect repellent device 2 preferably includes a total of one air permeable component 24 and one heating component 25.

[0062] One end of the heating element 25 in the length direction is fixedly connected to the base 21. After the medicine bottle 22 is connected to the base 21, the other end of the heating element 25 in the length direction is located inside the medicine bottle 22 and close to the bottom of the medicine bottle 22. In this embodiment, the length direction of the heating element 25 is preferably parallel to the length direction of the body 11.

[0063] The functional module 12 includes a power supply unit for supplying power to the positioning device 1 to realize the positioning function. The power supply unit can supply power to the insect repellent device 2 while supplying power to the positioning device 1. The power supply unit can energize the heating element 25 so that the portion of the heating element 25 extending into the insect repellent solution heats the insect repellent solution, thereby accelerating the volatilization of the insect repellent solution. In this embodiment, since heating the insect repellent solution to accelerate its volatilization is a common prior art, it will not be described in detail here, and only the heating element 25 is shown in the accompanying drawings.

[0064] The heating element 25 is located on one side of the liquid outlet tube 232, and one end of the heating element 25 close to the base 21 enters into the interior of the base 21, so that the power supply unit in the functional module 12 can power it, and the user can control whether the power supply unit powers the heating element 25 through several buttons 132 on the operation panel 13.

[0065] The air-permeable member 24 is movably mounted on a side of the base 21 away from the body 11 , and the movement of the air-permeable member 24 can control whether the insect repellent solution can diffuse outward after volatilization.

[0066] The air permeable member 24 is a cylindrical structure as a whole, and the base 21 is provided with a matching groove 213 adapted to the air permeable member 24 and a diffusion channel 212 for the anthelmintic solution to volatilize and diffuse outward. One end of the diffusion channel 212 is connected to the matching groove 213, and the other end of the diffusion channel 212 is connected to the inner space of the medicine bottle 22 after the medicine bottle 22 is connected to the base 21.

[0067] The air-permeable member 24 is threadedly matched with the peripheral groove wall of the matching groove 213 , and the air-permeable member 24 can be driven to move relative to the base 21 by controlling the air-permeable member 24 to rotate around its own axis.

[0068] The air permeable member 24 has a plurality of air holes 241 inside. In this embodiment, the air permeable member 24 preferably has one air hole 241 in total. The air hole 241 is opened along the axial direction of the air permeable member 24. One end of the air hole 241 passes through one end of the air permeable member 24 in the axial direction to form an opening. The other end of the air hole 241 forms a plurality of branches and passes through the circumference of the air permeable member 24 near the other end of the air permeable member 24 in the axial direction to form a plurality of openings.

[0069] The air-permeable member 24 has limited movement relative to the base 21, and the end of the air-permeable member 24 close to the base 21 can remain in the base 21 and can remain threadedly engaged with the matching groove 213. When the air-permeable member 24 moves to the extreme position in the direction close to the base 21, the air-permeable member 24 can block the communication port between the diffusion channel 212 and the matching groove 213, and the end of the air hole 241 close to the base 21 is also blocked by the groove wall at the bottom of the matching groove 213, and the openings of several branches of the air hole 241 are also located inside the base 21; when the air-permeable member 24 moves to the extreme position in the direction away from the base 21, the diffusion channel 212 communicates with the matching groove 213, and the openings of several branches of the air hole 241 are located outside the base 21, and the volatilized insect repellent diffused into the matching groove 213 can diffuse outward through the air hole 241.

[0070] Furthermore, to facilitate the user to control the movement of the breathable member 24 , the end of the breathable member 24 away from the base 21 has a handle 242 , and during the movement of the breathable member 24 relative to the base 21 , the handle 242 remains located on the side of the base 21 away from the body 11 .

[0071] In the process of the heating element 25 heating the insect repellent to accelerate its volatilization, in order to ensure its reliability and safety, it is necessary to ensure that the end of the heating element 25 away from the base 21 is immersed in the insect repellent, and to ensure that the position state of the multi-function GPS locator is that the medicine bottle 22 is located below the breathable element 24, so as to prevent the insect repellent in the medicine bottle 22 from flowing out directly through the diffusion channel 212.

[0072] Furthermore, in order to facilitate the multifunctional GPS locator to continue to drive away mosquitoes during the surveying process, the insect repellent device 2 also includes a plurality of support members 26. In this embodiment, the insect repellent device 2 preferably includes two support members 26 in total.

[0073] The support member 26 is a rod-shaped structure as a whole, one end of the support member 26 in the length direction is rotatably connected to the body 11, and the rotation axis of the support member 26 is parallel to the length direction of the base 21; the rotation connection position of the support member 26 and the body 11 is located at a position of the body 11 close to the base 21, and the rotation connection positions of the two support members 26 and the body 11 are respectively located on both sides of the length direction of the base 21.

[0074] The support member 26 is limited in the process of rotating relative to the body 11. Two clearance grooves 111 adapted to the support member 26 are provided on one side of the body 11 close to the base 21, and the two clearance grooves 111 correspond to the two support members 26 one by one. When the support member 26 rotates to the extreme position in the direction close to the body 11, the support member 26 enters the corresponding clearance groove 111, and the support member 26 is completely located inside the body 11; when the support member 26 rotates to the extreme position in the direction away from the body 11, the angle between the support member 26 and the body 11 is an acute angle, which is convenient for the user to stably place the multifunctional GPS locator on the ground with the two support members 26 and the end of the body 11 away from the display screen 131 as support, so that the breathable member 24 can remain above the medicine bottle 22, and improve the reliability and safety of the multifunctional GPS locator in the process of surveying by the surveyor to continue to play the role of repelling mosquitoes. In this embodiment, the maximum angle between the support member 26 and the body 11 is preferably 30°.

[0075] The implementation principle of a multifunctional GPS locator in the embodiment of the present application is:

[0076] When the surveyor holds the multifunctional GPS locator and goes to the designated place, the location of the designated place can be determined more accurately through the positioning device 1. At the same time, according to the situation of the surrounding mosquitoes, the pressing member 233 can be pressed to make the insect repellent in the medicine bottle 22 be sprayed out in the form of mist through the liquid outlet pipe 232, the liquid outlet channel 211 and the nozzle 231, which can effectively drive away mosquitoes and reduce the probability of the surveyor being bitten by mosquitoes when going to the designated place.

[0077] After the surveyor arrives at the designated location and before surveying the surrounding area, he first takes out the support member 26 to stably place the multifunctional GPS locator on the ground, then controls the breathable member 24 to move to the extreme position in the direction away from the base 21, and then controls the heating member 25 through the operation panel 13 to heat the insect repellent in the medicine bottle 22 to accelerate the volatilization of the insect repellent. The volatilized insect repellent diffuses outward through the diffusion channel 212, the matching groove 213 and the air hole 241 in turn, which can drive away mosquitoes within a certain range around the multifunctional GPS locator, and provide a certain protection effect for the surveyor during the survey.

[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
