Description

Technical Field

[0001] The invention relates to the technical field of mosquito repellent bracelets, and in particular to an adjustable mosquito repellent bracelet. Background Art

[0002] The mosquito repellent bracelets in the prior art generally adopt a single non-adjustable opening or closing bracelet, which is generally a disposable bracelet and cannot be reused repeatedly; such non-adjustable opening or closing bracelets are easy to get wet when opened and not in use, or are easy to get damp due to being opened for a long time; in the existing market, there is a mosquito repellent bracelet made of mosquito repellent material on the entire bracelet. When such a bracelet is worn, the mosquito repellent liquid or mosquito repellent potion on the bracelet will directly contact the human skin, and such mosquito repellent potion often contains certain trace toxins. If it contacts the human skin for a long time, the skin will also absorb these toxins and thus affect human health. Summary of the invention

[0022] A specific implementation of the present invention is described below with reference to the accompanying drawings.

[0023] Example 1: See Figures 1 to 6 , a switch adjustment device that can adjust the opening or closing state of the mosquito repellent bracelet is added on the basis of the existing mosquito repellent bracelet; in the present technical solution, the structures in the fixed block of the mosquito repellent bracelet are respectively a knob, a first columnar protrusion, a first gasket, a breathable spacer, a mosquito repellent sheet and a sealed bottom cover from top to bottom; when the mosquito repellent bracelet of the present technical solution does not need to repel mosquitoes, it only needs to rotate the knob to drive the first columnar protrusion to rotate circumferentially in the second through hole, and the circumferential rotation of the first columnar protrusion will drive the first gasket to rotate circumferentially in the first groove; and the first limiting protrusion on the upper end surface of the first gasket will slide circumferentially in the fourth annular groove on the bottom surface of the first groove. In the present technical solution, the first limiting protrusion is made of elastic rubber material. Therefore, when the first limiting protrusion rotates circumferentially in the fourth annular groove, since the fourth annular groove is provided with six holes for the first limiting protrusion to be embedded The first limiting groove and the lower end of the first through hole are connected to the first annular groove. When the mosquito repellent structure needs to be opened, it is only necessary to turn the knob to rotate the first limiting protrusion in the fourth annular groove to the first limiting groove until all 6 first limiting protrusions are embedded in the first annular groove, and the mosquito repellent through holes of the mosquito repellent bracelet are opened to the maximum; if the user feels that the smell of the mosquito repellent solution is too strong at this time, the knob can be turned again to rotate part of the first limiting protrusion to the lower end surface of part of the first through holes in the fourth annular groove, and the first limiting protrusion will block part of the first through holes so that the mosquito repellent odor molecules in the mosquito repellent sheet cannot be transmitted through the first through holes, thereby reducing the smell of the mosquito repellent solution; when the user does not need to use the mosquito repellent bracelet, it is only necessary to continue to turn the knob until the first limiting protrusion closes all the first through holes to complete the closing process of the mosquito repellent bracelet.

[0024] The mosquito repellent bracelet adopting the technical solution in Example 1 is in a sealed state when not in use, protecting the mosquito repellent smell of the mosquito repellent sheet from leaking out, thereby extending the use time of the mosquito repellent effect.

[0025] See also Figure 1 The technical solution adopted by the present invention to solve the above problems is: an adjustable mosquito repellent bracelet, including a bracelet 1 and a mosquito repellent sheet 2, a fixed block 3 is fixedly connected to the bracelet 1, a first groove 31 for placing the mosquito repellent sheet 2 is provided on the lower end surface of the fixed block 3, a rotary switch 4 and the mosquito repellent sheet 2 for repelling mosquitoes are slidably connected in the first groove 31, a plurality of first through holes 32 connected to the bottom surface of the first groove 31 are provided on the upper end surface of the fixed block 3, a second through hole 33 for the upper end of the rotary switch 4 to pass through the first groove 31 is provided in the center of the upper end surface of the fixed block 3, a knob 5 is fixedly connected to the upper end of the rotary switch 4 after passing through the second through hole 33, a sealed bottom cover 6 is clamped in the first groove 31, and a mosquito repellent sheet 2 is provided between the sealed bottom cover 6 and the rotary switch 4.

[0026] After adopting the above structure, the present invention has the following advantages compared with the existing structure:
