Technical Field
[0001] This utility model belongs to the field of underwear technology, specifically relating to a type of women's menstrual underwear. Background Technology
[0002] Currently, the functions of menstrual care products on the market are quite scattered. Antibacterial, self-heating, and massage functions are often distributed among different products. For example, antibacterial products are mainly underwear with antibacterial functions, using a variety of antibacterial materials and technologies in the crotch area; self-heating products are mainly waist support belts, uterine warming belts, etc., which need to be worn separately; massage is also mainly achieved through waist support belts, mainly targeting the abdomen, and lacking attention to the groin area, which can also relieve menstrual discomfort. In short, women need to use multiple products at the same time to meet their different needs during menstruation, which is inconvenient.
[0003] In existing technology, one solution involves fixing a graphite heating element in the area corresponding to the lower abdomen of women's underwear. The self-heating of this element provides warmth to the lower abdomen, thus preventing uterine coldness during menstruation. However, this solution only provides warmth to the lower abdomen. During menstruation, women need to keep their waist and lower back warm in addition to the lower abdomen. This means the underwear cannot provide warmth to other areas as needed, resulting in limited functionality and poor practicality. Furthermore, this underwear fails to alleviate discomfort in areas also affected by menstruation, such as the groin and inner thighs. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide women's menstrual underwear to solve the problem that the fixed warming area of existing women's underwear for menstruation makes it inconvenient to keep other areas warm as needed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A type of women's menstrual underwear, comprising:
[0007] trousers; and
[0008] A heating assembly is provided on the pants body. The heating assembly includes a movable channel, a sheet-shaped heating element, and a pull cord. The movable channel is located circumferentially on the inner or outer surface of the pants body and can at least cover a part of the lower abdomen. The heating element is slidably fitted in the movable channel. Openings are provided at both ends of the movable channel. The pull cord passes through the opening into the movable channel and is connected to the end of the heating element to pull the heating element to slide in the movable channel.
[0009] In one possible implementation, the active channel also covers at least a portion of the waist region of the human body circumferentially, including the lateral waist region and the posterior waist region.
[0010] In one possible implementation, the openings at both ends of the active channel are located on the same side.
[0011] In one possible implementation, a receiving cavity is provided below the channel segment corresponding to the lower abdomen region of the human body, and a sheet-shaped heating element is provided inside the receiving cavity. The channel segment corresponding to the lower abdomen region of the human body and the receiving cavity respectively cover the upper and lower parts of the lower abdomen region of the human body.
[0012] In one possible implementation, the top of the receiving cavity is connected to the active channel and the size of the connection is greater than or equal to the size of the second heating element.
[0013] In a possible implementation, both heating element one and heating element two are flexible heating elements.
[0014] In a possible implementation, when the active channel is located on the inner surface of the trouser body, the heating element one includes a cotton cloth layer one, a flexible graphene heating material layer and a cotton cloth layer two arranged from the inside out;
[0015] When the active channel is located on the outside of the pants, the heating element includes a cotton cloth layer, a flexible graphene heating material layer, and a polyester fiber layer arranged from the inside out.
[0016] In one possible implementation, the crotch area of the trousers is provided with an antibacterial layer.
[0017] In one possible implementation, the pants are boxer briefs, and the inner surface of the boxer briefs corresponding to the area at the root of the human thigh is provided with a massage layer, and the surface of the massage layer is distributed with protruding massage particles.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] This utility model of women's menstrual underwear features a heating element that can slide within a movable channel. The wearer can easily adjust the position of the heating element within the channel by pulling a drawstring, thereby facilitating the switching and adjustment of different areas of the body, including the lower abdomen. This provides greater flexibility and allows for the appropriate warming of different areas of the body as needed, better alleviating discomfort caused by menstruation and offering more functions.
[0020] Moreover, by extending the activity channel circumferentially and passing through areas such as the side waist and lower back, the wearer can adjust the heating element one to the position where warmth is needed, making operation convenient and flexible. Furthermore, the heating element two is set in the receiving cavity, which can provide warmth to the upper and lower parts of the lower abdomen area separately from the heating element one, resulting in a larger warming area and better effect.
[0021] Meanwhile, by setting antibacterial and massage layers in the groin and crotch areas of the pants, the growth of bacteria can be inhibited, maintaining a hygienic environment in the crotch area. The massage layer can also provide a squeezing and rubbing massage effect when the wearer walks and moves, relieving the soreness and swelling in the groin area that is common during menstruation.

Detailed Implementation
[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.
[0029] Please refer to Figure 1-5As shown, an embodiment of this application provides a pair of women's menstrual underwear, including: a pant body 1; and a heating component 2 disposed on the pant body 1. The heating component 2 includes a movable channel 21, a sheet-shaped heating element 22, and a pull cord 23. The movable channel 21 is disposed circumferentially on the inner or outer surface of the pant body 1 and can at least cover a part of the lower abdomen. The heating element 22 is slidably fitted in the movable channel 21. The movable channel 21 has openings 24 at both ends. The pull cord 23 passes through the openings 24 into the movable channel 21 and is connected to the end of the heating element 22 to pull the heating element 22 to slide within the movable channel 21.
[0030] The heating component 2 has a movable channel 21 that accommodates and allows the heating element 22 to slide within it. The heating element 22 can change its position within the movable channel 21 by sliding, thus allowing it to switch between heating and warming positions. The heating element 22 has a sheet-like structure, which facilitates sliding within the narrow movable channel 21. To prevent jamming during sliding, the two ends of the heating element 22 are chamfered, further facilitating its movement within the movable channel 21. The movable channel 21 can be formed by sewing a fabric layer along the side of the trousers 1, either inside or outside. When placed inside the trousers 1, it provides better warmth retention, while its warmth retention is relatively lower when placed outside. The specific configuration can be chosen based on the heat output of the heating element. The movable channel 21 can cover at least part of the lower abdomen area and can also cover other areas requiring warmth, facilitating the switching of warming positions. The sliding of the heating element 22 is initiated by the wearer through the pull cord 23, which passes through the openings 24 at both ends of the active channel 21 for easy pulling by the wearer.
[0031] Through the above technical solution, the heating element 22 of the heating component 2 can slide within the active channel 21, which allows the wearer to easily adjust the position of the heating element 22 within the active channel 21 by pulling the pull cord 23. This facilitates switching and adjusting different areas of the body, including the lower abdomen, providing greater flexibility and making it easier to keep different areas of the body warm according to needs. This better alleviates the discomfort caused by menstruation in women and provides more functions.
[0032] In one embodiment, the active channel 21 also covers at least a portion of the waist area of the human body circumferentially, the waist area including the lateral waist area and the posterior waist area.
[0033] In this way, the active channel 21 can cover the entire waist, including the lower abdomen area, and the heating element 22 inside can move circumferentially to most areas of the waist, thus making the adjustment and switching range larger, more flexible and practical.
[0034] To facilitate operation by the wearer, the openings 24 at both ends of the active channel 21 are located on the same side. This also makes it easier to tie and secure the pull cords 23 at both ends, making it more convenient to use.
[0035] In the embodiments of this application, the channel segment of the active channel 21 corresponding to the lower abdomen region of the human body is provided with a receiving cavity 25, and a sheet-shaped heating element 26 is provided in the receiving cavity 25. The channel segment of the active channel 21 corresponding to the lower abdomen region of the human body and the receiving cavity 25 respectively cover the upper and lower parts of the lower abdomen region of the human body.
[0036] The receiving cavity 25 is located below the channel section of the active channel 21 corresponding to the lower abdomen area of the human body. Its formation structure is the same as that of the active channel 21. It is also formed by sewing fabric into the inside or outside of the pants body 1 to form a cavity. The heating element 26 installed in the receiving cavity 25 is used to keep the lower part of the lower abdomen warm. It works with the heating element 22 to more completely cover the lower abdomen area and achieve a better warming effect. Furthermore, after the heating element 22 is adjusted to other areas, the heating element 26 can also keep the lower abdomen warm, achieving the effect of keeping different areas warm at the same time.
[0037] To facilitate the insertion and removal of the second heating element 26 from the receiving cavity 25, the top of the receiving cavity 25 is connected to the movable channel 21, and the size of the connection is greater than or equal to the size of the second heating element 26. During manufacturing, it is convenient to insert the flexible second heating element 26 into the receiving cavity 25 through the movable channel 21. During repairs, it is also convenient to first open the opening 24 and then remove the second heating element 26 through the movable channel 21, making it more convenient and practical.
[0038] Preferably, both heating element 22 and heating element 26 are flexible heating elements. Flexible heating elements have better flexibility and can better conform to the human body.
[0039] In a preferred embodiment of the heating element 22, combined with Figure 4 As shown, when the active channel 21 is located on the inner surface of the pants body 1, the heating element 22 includes a cotton cloth layer 221, a flexible graphene heating material layer 222, and a cotton cloth layer 223 arranged from the inside out.
[0040] Heating element 1 22 and heating element 2 26 have the same structure. Cotton layer 1 221 can improve comfort. The flexible graphene heating material layer 222 in heating element 1 22 is an existing heat-insulating and heating material commonly used by athletes. It has excellent heat-insulating and heat-generating capabilities. When the activity channel 21 is set on the inner surface, cotton layer 223 can play a simple outer layer role.
[0041] In another preferred embodiment of the heating element 22, combined with Figure 5 As shown, when the active channel 21 is located outside the pants body 1, the heating element 22 includes a cotton cloth layer 221, a flexible graphene heating material layer 222, and a polyester fiber layer 224 arranged from the inside out.
[0042] Compared to the setting of the abrasion material on the inner surface of the pants body 1, the outer layer of polyester fiber 224 can provide better abrasion resistance.
[0043] To achieve an antibacterial effect on the crotch area, the inner crotch layer of the trousers 1 is further provided with an antibacterial layer 3. The antibacterial layer 3 is located on the inner surface of the crotch area and is made of fabric with added antibacterial materials (such as silver ion antibacterial fibers, cotton fibers treated with natural plant antibacterial agents, etc.). The antibacterial materials inhibit the growth of bacteria such as Staphylococcus aureus and Escherichia coli, which are prone to proliferate during menstruation, by disrupting bacterial cell membranes and inhibiting the activity of bacterial metabolic enzymes, thus maintaining a hygienic environment in the crotch area.
[0044] In practice, the pants 1 are boxer briefs, and a massage layer 4 is provided on the inner surface of the pants 1 corresponding to the groin area of the human thigh. The surface of the massage layer 4 is covered with raised massage particles. The massage layer 4 with massage particles in the groin area is made of soft silicone or similar materials. When worn, the friction and pressure generated by walking and activity provide a gentle massage to the muscles and acupoints in the groin area, relieving the soreness and swelling in the groin area commonly experienced during menstruation.
[0045] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
