On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] It should be noted that unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0024] An embodiment of a pest repellent device in the present application is shown in Figures 1-4 The device housing 1 is provided with a release belt outlet 13 at the right bottom, and a winding roller 3 and a repellent release roller 10 are rotatably arranged in the device housing, the rotation axis of the winding roller 3 and the repellent release roller 10 extending along the front-back direction, the repellent release roller 10 has six control protrusions 11 uniformly spaced along the circumferential direction, the end of the control protrusions 11 away from the rotation axis of the repellent release roller 10 is arc-shaped, the winding roller is driven by a clockwork spring, the repellent release roller 10 is located at the right lower side of the winding roller 3, and a reversing roller 9 with the rotation axis extending along the front-back direction is also rotatably arranged in the device housing, the reversing roller 9 is located at the right side of the repellent release roller.

[0025] A repellent storage tank 2 is arranged above the repellent release roller on the device housing, the lower end of the repellent storage tank 2 has an outlet port 20 with the opening downward, and the outlet port 20 is a necked structure with the upper part larger and the lower part smaller. The pest repellent device further comprises a repellent release belt 8 passing between the outlet port and the repellent release roller, the repellent release belt 8 is a cloth belt (or a water-absorbing belt made of a high polymer material), one end of the repellent release belt 8 is wound on the winding roller 3, and the other end of the repellent release belt 8 is passed out through the release belt outlet 13. Specifically, one end of the repellent release belt 8 is wound on the winding roller 3, the other end of the repellent release belt 8 is passed between the repellent release roller and the repellent storage tank, and then is reversed by the reversing roller and is passed out through the release belt outlet.

[0026] A discharge control valve core 7 is movably arranged at the outlet port in the up-down direction, a return spring 15 is connected to the discharge control valve core 7, the discharge control valve core 7 has a discharging position for opening the outlet port by moving upward and a closing position for closing the outlet port by moving downward, and when the repellent release belt is pulled outward, the repellent release roller rotates in the positive direction, and each control protrusion pushes the discharge control valve core to the discharging position. In this embodiment, the discharge control valve core is a strip structure with the length extending along the front-back direction, the cross section of the discharge control valve core is a trapezoidal structure with the upper part larger and the lower part smaller, the discharge control valve core comprises a bottom surface 19, a top surface 16, and a left side slope 17 and a right side slope 18 arranged between the bottom surface and the top surface, the bottom surface 19 and the top surface 16 are both horizontally arranged planes, the left side slope 17 and the right side slope 18 are in sealing cooperation with the left and right inner walls of the outlet port when the discharge control valve core is in the closing position, and a discharging channel 21 is formed between the left side slope and the left inner wall of the outlet port and between the right side slope and the right inner wall of the outlet port when the discharge control valve core is in the discharging position.

[0027] The left side slope and the bottom surface are connected by a circular arc transition surface 22, and the right side slope and the bottom surface are connected by the circular arc transition surface 22. The circular arc transition surface has the following effects: 1. The circular arc transition surface can reduce the contact area between the bottom surface and the repellent release belt, thereby reducing the friction between the repellent release belt and the bottom surface; 2. The circular arc transition surface can avoid the repellent release belt being stuck at the bottom of the discharge control valve core during the back-and-forth movement of the repellent release belt; 3. The circular arc transition surface can increase the width of the lower end of the discharge passage, thereby increasing the contact area of the repellent release belt for absorbing the repellent.

[0028] A mounting plate 4 is arranged on the upper side of the discharge control valve core in the repellent storage tank, a material passing hole 5 is arranged on the mounting plate, a vertically arranged guide rod 6 is fixed on the mounting plate, the upper end of the discharge control valve core is provided with a guide groove for guiding the movement of the guide rod 6, the guide groove does not penetrate the discharge control valve core, and a reset spring 15 is sleeved on the outer periphery of the guide rod 6.

[0029] A scraper 14 is arranged at the outlet of the release belt, which is inclined from left to right towards the pulling-out direction of the repellent release belt. The scraper is located on the upper side of the repellent release belt. When winding, the scraper can scrape off the impurities and pests on the repellent release belt, avoiding these impurities from entering the device housing along with the collection of the repellent release belt.

[0030] In the embodiment, a housing pawl 12 is arranged on the device housing, a pawl reset spring is connected to the housing pawl 12, the housing pawl is located between two adjacent control protrusions 11 in the circumferential direction, and when the winding roller is winding, the housing pawl is in blocking cooperation with the corresponding control protrusion, so that the reverse rotation angle of the winding roller is not greater than the included angle of the two adjacent control protrusions in the circumferential direction, and the discharge control valve core is located between the two adjacent control protrusions on the upper position.

[0031] The use process of the repellent release belt is as follows: when the repellent release belt needs to be pulled out to release the repellent, the pawl reset spring is reset, the pawl is reset to the position of the control protrusion, the pawl is in blocking cooperation with the control protrusion, and the pawl is in the position of the control protrusion. Figure 1As shown, the operator can pull the repellent release belt outwards. During this pulling motion, the repellent release belt causes the repellent release roller to rotate clockwise. The pawl on the housing does not affect the clockwise rotation of the repellent release roller. When the repellent release roller rotates clockwise, and the control protrusion rotates to the bottom of the discharge control valve core, the control protrusion will push the discharge control valve core upwards. The discharge control valve core moves to the discharge position. At this time, the repellent in the repellent storage tank comes into contact with the repellent release belt through the left and right spaced discharge channels. After the repellent contacts the repellent release belt... The repellent gradually permeates the entire repellent release belt. As the repellent release roller continues to rotate clockwise, the discharge control valve core aligns with the recess between two adjacent control protrusions. Under the action of the return spring, the discharge control valve core moves downward and closes the discharge port. As the repellent release roller continues to rotate clockwise, the next control protrusion moves to the underside of the discharge control valve core and begins to push it out. This cycle repeats, allowing the repellent to be added intermittently to the repellent release belt, avoiding material waste caused by continuous addition. After the repellent release belt is pulled out, the end can be fixed. Through natural evaporation, the repellent can diffuse into the surrounding area.

[0032] When it is no longer necessary to release repellent, the operator loosens the fastener to the end of the repellent release strip. A spring-driven take-up roller rotates, winding up the repellent release strip. At this point, the repellent release roller tends to rotate counter-clockwise until the lower side of a corresponding control protrusion engages with the housing pawl. At this point, the repellent release roller can no longer rotate counter-clockwise. Figure 3 As shown, at this time, the discharge control valve core corresponds to the recess between two adjacent control protrusions. Under the action of the reset spring, the discharge control valve core is always in the closed position. At this time, the repellent release belt can pass through the gap between the control protrusion and the bottom of the repellent storage tank to achieve smooth winding. The transition arc surface can reduce the wear between the bottom of the discharge control valve core and the repellent release belt during the winding process.
