Abstract
Description
Technical Field
[0001] This utility model relates to the field of sweat-absorbing towel technology, and in particular to a sweat-absorbing towel with humidity monitoring function. Background Technology
[0002] Children are naturally active and energetic with a high metabolism, resulting in frequent and profuse sweating after vigorous exercise. I remember when I was little, my elders always dressed me in many layers of clothing, often leaving my back soaked with sweat and my undershirt damp. This was not only very uncomfortable, but also made me susceptible to catching a cold when exposed to cold drafts. Nowadays, parents often use sweat-absorbing towels to help their children absorb sweat and keep their backs and clothing dry, which helps prevent colds.
[0003] Developing smart sweat towels with humidity monitoring functions meets social needs. By reviewing existing relevant patent literature, it was found that most studies on humidity warning for sweat towels are implemented by embedding humidity sensors. The sensors monitor the humidity of the sweat towel in real time and send the data to smart terminals or other means to remind parents.
[0004] However, smart sweat towels with built-in sensors have some drawbacks. For example, high production costs lead to higher retail prices, which is not conducive to market promotion; built-in sensors and electronic components increase the difficulty of cleaning and maintenance; and they are not as soft and comfortable as traditional sweat towels, affecting breathability when worn, thus leaving room for improvement. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a sweat-absorbing towel with humidity monitoring functionality. Its advantages include the ability of sweat to seep into the color-changing display along the sweat-wicking strip, causing the display to change color and thus providing a warning effect. Furthermore, the color-changing component can be replaced via Velcro, allowing the sweat-absorbing towel to be reused multiple times after washing, reducing the overall cost of use.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A sweat-absorbing towel with humidity monitoring function includes a sweat-absorbing towel body, an anti-slip head is provided on the top of the sweat-absorbing towel body, a crease is provided between the sweat-absorbing towel body and the anti-slip head, and an inset opening is provided on the surface of the sweat-absorbing towel body, into which a color-displaying component is inserted.
[0008] The color-developing component includes a sweat-wicking strip, a color-developing sheet on the top of the sweat-wicking strip, a looped hook and loop fastener on the surface of the color-developing sheet, and a hook and loop fastener on the surface of the anti-slip head, the looped hook and loop fastener being compatible with each other.
[0009] With the above technical solution: When using, place one side of the sweat-absorbing towel against the baby's skin and tuck it into the baby's underwear at the back. Turn the anti-slip head out from the inside along the folds. After the sweat-absorbing towel absorbs sweat, the sweat will seep into the color indicator along the sweat-wicking strip, and the color indicator will change color, thus achieving a warning effect. At the same time, the color indicator component can be replaced with Velcro, making it convenient for the sweat-absorbing towel to be reused multiple times after washing, reducing the cost of using the sweat-absorbing towel.
[0010] The present invention is further configured such that a colorimetric indicator is disposed inside the colorimetric sheet, and the colorimetric indicator is a bromocresol green solution.
[0011] Through the above technical solutions, bromocresol green solution has a stable and rich color. When bromocresol green solution comes into contact with water, it changes from cyan to blue, making it an ideal colorimetric indicator and improving the indicator effect.
[0012] The present invention is further configured such that a carrier substrate is disposed inside the color developing sheet, and the carrier substrate is made of cotton cloth.
[0013] The above technical solution allows the cotton cloth to easily hold the color indicator, improving the uniformity of coloring.
[0014] The present invention is further configured such that the outer wall of the anti-slip head away from the hook and loop fastener has a rough surface structure.
[0015] The above technical solution, with its textured surface design, increases friction when the towel comes into contact with clothing, preventing it from slipping off.
[0016] The present invention is further configured such that the sweat-absorbing towel body is made of four layers of sweat-absorbing material sewn together.
[0017] The above technical solution involves four layers of sweat-absorbing material sewn together to create a thicker sweat-absorbing towel body, which improves the water absorption capacity of the towel body.
[0018] The present invention is further configured such that the four-layer sweat-absorbing material includes two layers of pure cotton, a layer of bamboo cotton, and a layer of cotton yarn, wherein the bamboo cotton layer and the cotton yarn layer are located between the two layers of pure cotton.
[0019] Through the above technical solutions, the pure cotton layer, bamboo cotton layer, and cotton yarn layer all have good water absorption. The fact that both the front and back are made of pure cotton improves the skin-friendly effect of the sweat-absorbing towel and increases the comfort during use.
[0020] The beneficial effects of this utility model are as follows:
[0021] 1. This sweat-absorbing towel with humidity monitoring function is used by placing one side of the towel against the baby's skin and tucking it into the baby's underwear at the back. The anti-slip head is then turned out along the folds. After the towel absorbs sweat, the sweat will seep into the color indicator along the sweat-wicking strips, causing the indicator to change color and thus providing a warning effect. At the same time, the color indicator can be replaced with Velcro, making it convenient to reuse the sweat-absorbing towel multiple times after washing, reducing the cost of using the towel.
[0022] 2. This sweat-absorbing towel with humidity monitoring function uses bromocresol green solution, which has a stable and rich color. Bromocresol green solution changes from cyan to blue when it comes into contact with water, making it an ideal color indicator and improving the indicator effect. The cotton cloth can easily hold the color indicator, improving the uniformity of coloring. Attached Figure Description
