Description

Technical Field

[0001] This application belongs to the field of sleepwear technology, specifically relating to a multifunctional sleepwear. Background Technology

[0002] Pajamas, as a common type of home wear in modern life, are designed specifically for sleeping and leisure at home, and have the advantages of being loose and comfortable.

[0003] Winters in the north are cold, and extra warmth is needed for afternoon naps. Traditional pajamas can only cover most of the body (torso, arms and legs), but cannot cover the hands and feet. When napping at the office or at home, the feet and hands cannot be kept warm, and shoes need to be worn to keep the feet warm, which affects the sleep experience. In addition, pajamas can only slow down the loss of body heat and are not very effective at keeping warm. In order to improve the insulation effect, extra clothes need to be added. Utility Model Content

[0004] This application provides a multifunctional pajama set, which aims to solve the technical problem that traditional pajamas in the prior art are not comfortable for naps and require additional warmth for the hands and feet.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A multi-functional pajama set is provided, comprising: The inner layer is designed to fit snugly against the human body. The outer layer is exposed to the external environment, and the outer layer and the inner layer are sewn together as one piece; A heating layer, disposed between the inner layer and the outer layer, is electrically connected to a power source to generate heat; and A wrapping layer is provided at the hem of the inner layer, and the wrapping layer and the outer surface of the inner layer enclose a space that can cover the feet.

[0006] In one possible implementation, the heating layer includes: The first layer, one side of which is connected to the inner layer; The second layer, connected to the outer layer on one side, and the first and second layers are bonded together to form a serpentine heating space; and A heating wire is placed within the heating space, with one end of the heating wire extending through the second layer and the outer layer and electrically connected to a power source.

[0007] In one possible implementation, the multifunctional pajamas also include a movable plug connected to one end of the heating wire, the movable plug being used for conductive connection to a power source; The outer surface of the outer layer has a receiving pocket, and the movable plug can be placed in the receiving pocket.

[0008] In one possible implementation, the outer layer is a fluffy layer.

[0009] In one possible implementation, the inner layer is a cotton layer or a silk layer.

[0010] In one possible implementation, the wrapping layer includes a wrapping fabric and a button, the wrapping fabric being sewn to the inner layer and having an opening at the top of the wrapping fabric to form the receiving space, the button being attached to the top of the wrapping fabric; The inner layer has a buckle corresponding to the button, and the buckle can be fastened to the button.

[0011] In one possible implementation, the bottom of the inner layer and the outer layer have folded edges that fold upward from the outside to the inside to form the wrapping layer, and the sides of the folded edges are sewn to the inner layer.

[0012] In one possible implementation, an inflatable assembly is installed at the collar of the outer layer. The inflatable assembly includes a fabric layer and an air bladder. The fabric layer is connected to the collar of the outer layer. The air bladder is located inside the fabric layer, and the air inlet and outlet of the air bladder extend out of the fabric layer.

[0013] In one possible implementation, a kangaroo pouch is provided in the middle of the outer surface of the outer layer for holding a human hand.

[0014] In one possible implementation, the collar of the multifunctional pajamas may also be detachably connected to a hood.

[0015] The multifunctional pajamas provided in this application, compared with existing technologies, feature an inner layer at the hem that forms a dedicated foot-covering space, completely enclosing the feet. This inner layer is integrated with the main body of the pajamas, eliminating the need for additional socks or shoes. This avoids the restrictive feeling of shoes that disrupts the sleep experience and locks in foot warmth through the airtight design, preventing feet from getting cold during afternoon naps in northern winters. The heating layer uses active electrical heating instead of passive warmth, with the heat generated directly transferred to the body through the inner layer. Simultaneously, the integrated stitching structure of the inner and outer layers forms a heat barrier, reducing heat loss and improving insulation. During afternoon naps in northern winters, there is no need to wear an extra coat or blanket, significantly reducing the burden of clothing. Furthermore, the heating temperature is stable, eliminating reliance on additional warm clothing. The heating layer is sandwiched in the middle, preventing direct skin contact and burns, thus balancing safety and warmth. Attached Figure Description

[0025] Please refer to the following: Figures 1 to 11 The multifunctional pajamas provided in this application are described below. The multifunctional pajamas include an inner layer 1, an outer layer 2, a heating layer 3, and a wrapping layer 4. The inner layer 1 is designed to fit snugly against the body; the outer layer 2 is exposed to the external environment, and the outer layer 2 and the inner layer 1 are sewn together; the heating layer 3 is located between the inner layer 1 and the outer layer 2, and is electrically connected to a power source to generate heat; the wrapping layer 4 is located at the hem of the inner layer 1, and the wrapping layer 4 and the outer surface of the inner layer 1 enclose a space that can cover the feet.

[0026] It should be noted that the outer layer 2 and the inner layer 1 are sewn together, and the heating layer 3 will not be exposed. The sewing process is common knowledge in this field.

[0027] It should be noted that the multifunctional pajamas provided in this embodiment can be worn normally while moving around the house. When you need to take a nap or rest, simply put on the pajamas and insert your feet into the space formed between the wrapping layer 4 and the inner layer 1 to keep your feet warm. When you feel cold, the heating layer 3 can be connected to a power source to generate heat and warm the body, ensuring a cold-resistant effect.

[0028] It should be noted that the multifunctional pajamas of this application can be connected to the two side plackets and inner plackets in different ways, such as by fastening or by tying with straps. See reference [link to relevant documentation]. Figure 9 .

[0029] The multifunctional pajamas provided in this embodiment, compared with the prior art, form a dedicated foot-enclosing space by using the wrapping layer 4 at the hem of the inner layer 1, which can completely cover the feet. The wrapping layer 4 is integrated with the main body of the pajamas, eliminating the need to wear additional socks or shoes. This avoids the restrictive feeling of shoes that would disrupt the sleep experience, and the airtightness of the wrapping layer 4 locks in warmth for the feet, preventing them from getting cold during afternoon naps in northern winters. The heating layer 3 uses active electrical heating instead of passive warmth. The heat generated by the heating layer 3 can be directly transferred to the human body through the inner layer 1. At the same time, the integrated sewn structure of the inner layer 1 and the outer layer 2 forms a heat barrier, reducing heat loss to the outside. During afternoon naps in northern winters, there is no need to wear an extra coat or blanket, greatly reducing the burden of clothing. The heating temperature is stable, eliminating the dependence on additional warm clothing. The heating layer 3 is sandwiched in the middle, avoiding direct contact with the skin and preventing burns, thus balancing safety and warmth.

[0030] In some embodiments, see Figure 4 and Figure 5 The heating layer 3 includes a first layer 31, a second layer 32, and a heating wire 33. One side of the first layer 31 is connected to the inner layer 1; one side of the second layer 32 is connected to the outer layer 2. The first layer 31 and the second layer 32 are attached to each other and form a serpentine heating space. The heating wire 33 is placed in the heating space, and one end of the heating wire 33 extends through the second layer 32 and the outer layer 2 and is electrically connected to the power source.

[0031] In practice, the inner layer 1 and the outer layer 2 are sewn together at specific locations to form a space for placing the heating layer 3, thus preventing the heating layer 3 from shifting and improving the stability of use.

[0032] It should be noted that both the first layer 31 and the second layer 32 are made of flame-retardant fabric to prevent the outer layer 2 or the inner layer 1 from catching fire due to the heating wire 33, thus ensuring safety during use.

[0033] It should be noted that a temperature controller is installed at the conductive end of the heating wire 33. The use of a temperature controller is existing technology; the controller can keep the resistance wire temperature below 50°C to prevent overheating.

[0034] It should be noted that the heating wire 33 is a heating composite, made of nickel-chromium alloy or iron-chromium-aluminum alloy, with stable power. The heating wire 33 is distributed in a serpentine pattern to avoid local overheating caused by adjacent heating wires 33 being too close together.

[0035] This embodiment provides a serpentine heating space, which ensures uniform heating and avoids uneven local heating. The serpentine path can cover the main warming areas of the torso and arms (such as the back, waist, and upper arms), and the path spacing is uniform. After the heating wire 33 is placed in it, the heat generated by the heating wire 33 can be evenly diffused along the serpentine path, transferred through the first layer 31 to the inner layer 1, and then covered to the key parts of the human body to ensure the heating effect. The first layer 31 and the second layer 32 are respectively connected to the inner layer 1 and the outer layer 2, completely enclosing the heating wire 33 in the closed heating space. On the one hand, the heating wire 33 does not directly contact the inner layer 1, and the heat needs to be buffered by the first layer 31 before being transferred, avoiding direct skin contact with the high-temperature heating wire 33 and causing burns. On the other hand, the double-layer structure can isolate external friction, prevent the heating wire 33 from breaking or leaking due to wear, and at the same time prevent the heating wire 33 from shifting, improving the safety of use and the durability of the heating layer 3.

[0036] In some embodiments, see Figure 3 The multifunctional pajamas also include a movable plug 5, which is connected to one end of the heating wire 33 and is used to make a conductive connection with a power source; the outer surface of the outer layer 2 has a accommodating pocket, in which the movable plug 5 can be placed.

[0037] It should be noted that the conductive end of the heating wire 33 is connected to the wire, which is exposed to the environment and will not leak electricity. The wire is connected to the mobile plug 5.

[0038] Optionally, the portable plug 5 has a USB port. It can be flexibly connected to different power sources (household sockets, portable power banks, office extension cords) via a charging head. The plug connects directly to the heating element 33, allowing users to adjust the power connection method according to their nap location. When not powered on, the portable plug 5 can be completely placed in the pocket to prevent it from snagging on the armrests of the office chair or sofa crevices, reducing interference with movement. The pocket also protects the metal contacts of the plug from dust and water damage, extending its lifespan. The plug-in / out-of-pocket design of the portable plug 5 requires no professional operation, making it easy for people of all ages to connect. The pocket's location (outer surface of the outer layer 2, such as the side of the waist) allows for easy access, eliminating the need to remove pajamas to store or retrieve the plug. After waking up, disconnect the power, place the plug in the pocket, and you can continue moving around in your pajamas without needing to store the plug separately, enhancing convenience.

[0039] In some embodiments, the outer layer 2 is a fleece layer. The fleece layer has a fluffy fibrous structure and can store a large amount of still air inside. This can both prevent cold air from entering the inside of the pajamas and avoid cold air directly contacting the heating layer 3, thus preventing heat loss, and also lock in the heat generated by the heating layer 3, reducing heat diffusion to the outside. The fleece layer has a soft and skin-friendly surface, enhancing the user's comfort when in contact with the outer layer 2 of the pajamas in the outdoors. In northern winters, the home environment is prone to dust, and the high fiber density of the fleece layer makes it difficult to attract fine dust. Daily cleaning only requires a gentle pat to remove surface dust, eliminating the need for frequent washing. At the same time, the fleece layer has better abrasion resistance than ordinary cotton layers, making it less prone to pilling and snagging with long-term wear, thus extending the lifespan of the outer layer 2 of the pajamas and reducing maintenance costs.

[0040] In practice, the outer layer 2 fabric can be made of artificial rabbit fur, coral fleece, flannel, knitted cotton, polyester fiber blends, or thin Tencel, which have good heat insulation effects.

[0041] In some embodiments, the inner layer 1 is a cotton layer or a silk layer.

[0042] The cotton layer has a naturally porous structure and strong moisture absorption capacity. During a nap in northern winters, if the heating layer 3 causes slight sweating, the cotton layer quickly absorbs the sweat and evaporates it through the fiber gaps, preventing sweat from remaining on the skin and causing a stuffy feeling. At the same time, the cotton layer is soft and skin-friendly, without chemical irritation, making it suitable for sensitive skin. It does not cause friction or discomfort when in contact with the skin, improving comfort. Silk is a natural protein fiber with extremely high compatibility with human skin, and will not cause allergies or irritation, making it suitable for people with delicate skin. The silk layer also has a low thermal conductivity, providing a warm and moist feeling when in contact with the skin. When the heating layer 3 heats up, excess heat can be dissipated through the gaps in the silk fibers, preventing overheating and stuffiness, balancing warmth and breathability.

[0043] Both the cotton layer and the silk layer are excellent heat conduction media. The heat generated by the heating layer 3 can be evenly transferred to the skin through the inner layer 1. The heat will not accumulate in the heating layer 3 due to the excessive heat insulation of the material. At the same time, both materials have good heat resistance and will not cause the inner layer 1 to deform or shrink due to the heat generated by the heating layer 3, thus balancing heat transfer efficiency and material stability.

[0044] Optionally, the inner layer 1 can also be made of bamboo fiber or modal.

[0045] In some embodiments, see Figure 8 The wrapping layer 4 includes a wrapping fabric 41 and buttons 42. The wrapping fabric 41 is sewn to the inner layer 1, and an opening is provided at the top of the wrapping fabric 41 to form a receiving space. The buttons 42 are installed at the top of the wrapping fabric 41. The inner layer 1 has a drawstring 11 corresponding to the buttons 42, which can be fastened to the buttons 42. If the opening of the wrapping layer 4 is fixed, the opening is prone to collapsing during normal wear, affecting the user's walking experience. The drawstring 11 can be fastened to the buttons 42 to connect the wrapping layer 4 to the inner layer 1, so that the wrapping layer 4 can fit snugly against the inner layer 1 when not in use. When the user needs to put their foot into the receiving space, the buttons 42 and the drawstring 11 can be separated to facilitate foot movement, improve the sleeping experience, and not restrict the local movement of the foot.

[0046] In some embodiments, see Figure 6 and Figure 7 The bottom of the inner layer 1 and the outer layer 2 have folded edges that fold upwards from the outside to the inside to form the wrapping layer 4. The sides of the folded edges are sewn to the inner layer 1. The folded edge structure saves materials and reduces production costs: This design eliminates the need for additional cutting and sewing of the separate wrapping fabric 41. Instead, it utilizes the original fabric at the bottom of the inner layer 1 and outer layer 2, folding it upwards to form the wrapping layer 4. This reduces fabric waste and sewing processes, requiring only the side edges of the folded edge to be sewn, thus reducing production time and labor costs and making the product more cost-effective and suitable for the general consumer group. The folded edge is made of the original fabric of the inner layer 1 and outer layer 2, which is completely consistent with the main body of the pajama. When the feet come into contact with it, there will be no foreign body sensation due to the difference in feel between the separate wrapping fabric 41 and the main body fabric, increasing comfort. Feet can move more freely during naps, without stiffness caused by the overly stiff material of the wrapping layer 4. After the folded edge is folded upwards from the outside to the inside, it only requires sewing the side edges to fix it. This ensures that the wrapping layer 4 will not come undone when the feet are put on and taken off, while retaining the top opening to prevent the seams from breaking during long-term wear and take-off. Furthermore, the fabric of the folded edge is integrated with the main body, preventing fabric fatigue and damage due to frequent folding, thus improving the durability of the wrapping layer 4.

[0047] In some embodiments, see Figure 11An inflatable component 6 is installed at the collar of the outer layer 2. The inflatable component 6 includes a fabric layer 61 and an air bladder 62. The fabric layer 61 is connected to the collar of the outer layer 2. The air bladder 62 is located inside the fabric layer 61, and its air inlet and outlet protrude from the fabric layer 61. After inflating the air bladder 62 at the collar, the air bladder 62 expands and supports the fabric layer 61, making the fabric layer 61 fit snugly against the neck. This not only prevents cold air from entering the pajamas through the collar but also directly transmits warmth to the neck. After the air bladder 62 expands, the fabric layer 61 contacts the neck, reducing heat loss. The inflated air bladder 62 provides a certain degree of support, allowing the user to rest their head on the inflated collar. The air bladder 62 supports the weight of the head, reducing pressure on the cervical spine and preventing neck pain and dizziness after a nap, thus improving the quality of the nap. When napping at home, if a pillow is available, the air bladder 62 can be deflated, and the collar will return to its flat state without affecting normal use. In practice, the fabric layer 61 protects the airbag 62, which is encased inside the fabric layer 61, preventing the airbag 62 from directly contacting the skin and also preventing the airbag 62 from being scratched by the armrests of office chairs or the corners of sofas. After inflation, the overall appearance of the pajamas will not be damaged, and the fabric layer 61 is soft and does not feel cold when in contact with the neck, improving the tactile comfort. The air inlet and outlet protrude from the fabric layer 61, making it convenient for users to inflate with their mouths or an air pump. The operation is simple and requires no additional tools.

[0048] In some embodiments, see Figure 2 The outer layer 2 also has a kangaroo pouch 21 in the middle of its outer surface, which is used to place hands. The kangaroo pouch 21 is open from side to side without any partitions, so both hands can be put in at the same time. The space inside the pouch can cover the palm to the wrist, locking in the heat of the hands. At the same time, the heat generated by the heating layer 3 can be transferred to the inside of the pouch through the outer layer 2, making the temperature inside the pouch higher than the outside temperature. When taking a nap, the hands are warm and unrestricted when put in the pouch, avoiding cold hands from affecting sleep. The hands will not slip out after being put in, so there is no need to frequently adjust the position of the hands during the nap, improving the continuity of rest.

[0049] In some embodiments, see Figure 10 The multifunctional pajamas also feature a detachable hood 7 at the collar. This detachable hood 7 covers the head, and its edges naturally conform to the face (e.g., covering above the eyebrows), preventing cold air from directly contacting the scalp and reducing discomfort caused by a cold head. The hood 7 uses a detachable connection (e.g., snaps, zippers), allowing for warmth during naps and removal during daily activities without affecting the normal wearing of the pajamas. The pajamas themselves provide sufficient warmth for all areas, significantly enhancing the product's overall warmth while reducing the burden of carrying and storing additional thermal wear.

[0050] In practice, the hood 7 and the multifunctional pajamas are connected by either a zipper or snaps, both of which are conventional techniques for hood installation in this field and will not be elaborated further here.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
