[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a pest repelling device, including a storage tank 1, a drive motor 3 fixedly connected to one side of the storage tank 1, a transmission shaft 301 fixedly connected to the output end of the drive motor 3, an elliptical wheel 302 fixedly connected to the transmission shaft 301, an upper column cover 4 slidably installed inside the storage tank 1, the upper column cover 4 and the elliptical wheel 302 cooperate with each other, a plurality of conveying holes 406 are opened inside the upper column cover 4, a return spring 2 is fixedly connected to the bottom inside the storage tank 1, and the other end of the return spring 2 is fixedly connected to the bottom of the upper column cover 4.

[0021] In this embodiment, by adding a certain amount of repellent to the storage tank 1, the repellent will evaporate and diffuse into the internal space of the storage tank 1 over time. Starting the drive motor 3 can drive the transmission shaft 301 to rotate, which in turn drives the elliptical wheel 302 to rotate. The elliptical wheel 302 is located below the upper cylindrical cover 4, and its overall shape is elliptical. When the long side of the rotating elliptical wheel 302 gradually contacts the upper cylindrical cover 4, it will push against the lower end of the upper cylindrical cover 4, causing the upper cylindrical cover 4 to move upward. At this time, the internal space of the storage tank 1 will increase, thereby allowing outside air to escape. The repellent will be sucked into the storage tank 1 through the conveying hole 406. When the short side of the elliptical wheel 302 gradually contacts the lower end of the upper column cover 4, the lower end of the upper column cover 4 will lose the pushing action of the elliptical wheel 302. The upper column cover 4 will move back to its original position under the pull of the return spring 2. At this time, the internal space of the storage tank 1 will shrink, and the air mixed with the repellent inside the storage tank 1 will be squeezed out through the conveying hole 406 and diffused around the storage tank 1, spreading the volatile repellent to the surroundings to repel pests. At the same time, the repellent is stored inside the storage tank 1, which can effectively prevent animals from accidentally ingesting it.

[0022] In order to accelerate the evaporation rate of the repellent, the device adopts the following technical solution: a heating block 101 is fixedly connected to the center of the bottom of the storage tank 1, a limiting groove 102 is opened on the inner wall of the storage tank 1, a limiting protrusion 103 is fixedly connected in the limiting groove 102, a limiting flange 404 is fixedly connected to the outer wall of the upper column cover 4 near the lower edge, the limiting flange 404 slides with the limiting groove 102, a limiting slot 405 is opened on the outer wall of the limiting flange 404, and the limiting slot 405 cooperates with the limiting protrusion 103.

[0023] By activating the heating block 101, the repellent inside the storage tank 1 can be heated, accelerating the evaporation rate of the repellent. The limiting slide groove 102 slides with the limiting protrusion 404, which can limit the up and down movement of the upper column cover 4. The limiting slot 405 and the limiting protrusion 103 cooperate with each other to limit the upper column cover 4 to only move up and down, preventing the upper column cover 4 from rotating and causing the return spring 2 to become misaligned.

[0024] To avoid friction between the elliptical wheel 302 and the bottom of the upper column cover 4, the device employs the following technical solution: the outer wall of the elliptical wheel 302 is provided with several contamination grooves 303, the upper column cover 4 is provided with a filling port 402, a sealing cap 403 is threaded onto the upper end of the filling port 402, and an installation groove is provided on the bottom of the upper column cover 4, in which a roller shaft 401 is rotatably installed, and the roller shaft 401 cooperates with the elliptical wheel 302.

[0025] A certain amount of repellent can be added into the storage tank 1 through the filling port 402. The sealing cap 403 can block the upper end of the filling port 402. The roller 401 and the elliptical wheel 302 cooperate with each other. When the elliptical wheel 302 rotates, the roller 401 and the elliptical wheel 302 are disengaged to avoid the elliptical wheel 302 rubbing against the bottom of the upper column cover 4. The contamination groove 303 is located on the surface of the elliptical wheel 302. When the elliptical wheel 302 rotates, part of the elliptical wheel 302 is located in the repellent in the storage tank 1. When the elliptical wheel 302 rotates, a certain amount of repellent can be adsorbed by the contamination groove 303. The rotating elliptical wheel 302 makes it easier for the repellent to evaporate.

[0026] The working principle and usage process of this utility model are as follows: When in use, a certain amount of repellent needs to be added into the storage tank 1. The heating block 101 is activated to heat the repellent inside the storage tank 1. At this time, the repellent will evaporate and mix with the air inside the storage tank 1. The drive motor 3 is activated to drive the elliptical wheel 302 to rotate. The elliptical wheel 302 cooperates with the return spring 2 to drive the upper column cover 4 to move up and down. When the upper column cover 4 moves up, the space inside the storage tank 1 will increase, and then the outside air will be drawn into the storage tank 1 through the conveying hole 406. When the upper column cover 4 moves down, the space inside the storage tank 1 will decrease, and then the air mixed with the repellent inside the storage tank 1 will be squeezed out through the conveying hole 406 and diffused around the storage tank 1, spreading the evaporated repellent to the surrounding area, thereby repelling the surrounding pests.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
