Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermostatic wristband technology, specifically to a thermostatic wristband that can be filled with fragrance. Background Technology
[0002] As people increasingly pursue health and comfort, an innovative product combining aromatherapy and temperature regulation has emerged on the market—the fragrance-fillable thermostatic bracelet. This bracelet not only emits the user's favorite scents to help relax and reduce stress, but also features a temperature control system to provide the wearer with a continuous feeling of warmth or coolness, suitable for different seasons and personal preferences. Common thermostatic bracelets consist of a main body and a strap, and the following drawbacks have been found during use:
[0003] 1. Current designs often make the caps difficult to open, especially when fragrances need to be changed frequently, which inconveniences users. For example, if the cap is designed to be too tight, additional tools may be required to open it, increasing the complexity of the operation.
[0004] 2. Everyone's wrist size and preferences are different, and a fixed watch strap length and material cannot meet everyone's needs. In addition, over time, the watch strap may wear out or get dirty, but existing designs usually do not allow users to quickly replace the strap themselves, limiting the product's lifespan and hygiene.
[0005] Therefore, based on this, we studied and improved the existing structure and proposed a temperature-controlled wristband that can be filled with fragrance. Utility Model Content

Detailed Implementation
[0026] 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.
[0027] Please see Figure 1-2 A temperature-controlled wristband that can be filled with fragrance includes a main body 1 and a strap 2; the strap 2 can be any one of an elastic strap, a magnetic strap, a pin buckle strap, a folding buckle strap, a hook buckle strap, or a nylon strap.
[0028] Please see Figure 1-4 The main body 1 includes a shell 101. A heat insulation layer 102 is fixedly installed at the bottom of the shell 101 to provide heat insulation. A constant temperature electric heating layer 103 is installed inside the shell 101 at the top of the heat insulation layer 102. A fragrance storage layer 104 is installed inside the shell 101 at the top of the constant temperature electric heating layer 103. A rotating dial 106 is installed on one side of the shell 101 to control the switch of the constant temperature electric heating layer 103. A timer is installed inside the rotating dial 106 to turn off the constant temperature electric heating layer 103 at a time. The fragrance storage layer 104 stores fragrances and the constant temperature electric heating layer 103 heats the fragrances at a constant temperature. An entrance for fragrances to enter the fragrance storage layer 104 is provided at the top of the shell 101. A cover 105 is hinged at the entrance. A receiving frame 107 for receiving the cover 105 is fixedly installed at the top of the shell 101 around the entrance.
[0029] Please see Figure 1-4The cover 105 is provided with a snap-fit component 3, and the snap-fit component 3 is snapped into the housing 101. The snap-fit component 3 includes a movable groove 301 provided on the housing 101. A movable plate 302 is slidably provided in the movable groove 301. A latch 303 is fixedly provided on one side of the movable plate 302, which movably passes through one side of the cover 105. The latch 303 is snapped into the housing 101, thereby closing the housing 101. The movable plate 302 is fixedly connected to one side of the movable groove 301 by a spring 304. The spring 304 can push the movable plate 302.
[0030] Please see Figure 1-4 Both sides of the housing 101 are provided with connecting components 4 for connecting to the watch strap 2, and the connecting rod 401 on the connecting component 4 is detachable. The connecting component 4 includes two receiving plates 402 fixedly installed on the housing 101, and the connecting rod 401 is movably installed between the two receiving plates 402. The watch strap 2 is sleeved on the connecting rod 401. A connecting piece 403 is threaded through the receiving plate 402, and the two connecting pieces 403 are respectively movably sleeved on both ends of the connecting rod 401. The connecting piece 403 is threadedly connected to the corresponding receiving plate 402. The connecting piece 403 rotates on the receiving plate 402, thereby moving the connecting piece 403. When the connecting rod 401 is stuck between the two connecting pieces 403, the connection between the connecting rod 401 and the connecting piece 403 can be realized.
[0031] The working principle of this utility model:
[0032] When the thermostatic wristband is needed, the movable plate 302 can be moved toward the spring 304. At this time, the locking rod 303 will leave the housing 101, allowing the cover 105 to be rotated. Fragrance can then be filled into the fragrance storage layer 104. The movable plate 302 can then be moved toward the spring 304, and the cover 105 can be rotated to the receiving frame 107. The movable plate 302 can then be released. The elastic force of the spring 304 will push the movable plate 302 to move, causing the locking rod 303 to engage with the housing 101, thereby closing the entrance. The rotating dial 106 can then be rotated to activate the thermostatic heating layer 103, heating the fragrance so that the aroma can diffuse from the gap between the housing 101 and the cover 105.
[0033] If the watch strap 2 needs to be replaced, the connector 403 can be rotated to remove the connecting rod 401 from the connector 403. Then the watch strap 2 can be removed from the connecting rod 401. The watch strap 2 to be replaced can then be put on the connecting rod 401. Next, the connecting rod 401 with the watch strap 2 on it is placed between the two connectors 403. Then the connector 403 can be rotated so that the connector 403 can be put on the connecting rod 401, thus completing the replacement of the watch strap 2.
[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
