[0044] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0045] Embodiment 1 (Large "T" - shaped special planar form + slide - rail - type adjustable suspension system)

[0046] Please refer to Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 , a three - dimensional enclosed leg - warming electric blanket, comprising:

[0047] The three-dimensional protective leg warming electric blanket body 1 is a multi-layer composite structure, including an outer layer 11 and a middle electric heating layer (12). The outer layer 11 and the middle electric heating layer 12 are made of deformable flexible material. The outer layer 11 is made of fluffy and soft plush fabric. The middle electric heating layer is equipped with heating elements 121. The outer layer 11 is provided with a U-shaped zipper, so that the outer layer 11 can be opened from the zipper to take out or put on the middle electric heating layer 12, which is convenient for cleaning the outer layer (11).

[0048] The three-dimensional protective leg warming electric blanket body 1 unfolds into a large "T"-shaped irregular planar shape with topological optimization design. It has a longitudinal main piece and a transverse extension piece. After three-dimensional reconstruction, its longitudinal main piece is, in sequence, an upper covering part 101 for covering the upper thigh, a front covering part 102 for covering the front of the lower limb, and an end covering part 105 for covering the foot. The transverse extension piece is, in sequence, a left wing part 103 for covering the left side of the lower limb, an upper covering part 101 for covering the upper thigh, and a right wing part 104 for covering the right side of the lower limb. Through the first set of detachable connectors 111 provided at the corresponding edge of the front covering part 102 and the left wing part 103 that are pre-connected to the outer layer 11, and the second set of detachable connectors 112 provided at the corresponding edge of the front covering part 102 and the right wing part 104 that are pre-connected to the outer layer 11, its three-dimensional shape is maintained, forming a three-dimensional protective structure that adapts to the physiological curve of the human lower limb in a sitting posture.

[0049] The outer layer 11 has matching fastening components 113 that can be repeatedly opened and closed at symmetrical positions on the outer edges of the left protective wing 103 and the right protective wing 104.

[0050] The suspension adjustment system 2 uses a track-type adjustment to switch between the raised suspension state and the lowered use state of the three-dimensional enclosed leg warming electric blanket body 1. Specifically, the base assembly 21 includes two parallel tracks 2100. Each track 2100 has a sliding locking member 2110 that can slide within the track. The sliding locking member 2110 has a bullnose-shaped structure that can connect to the suspension assembly 22 and a ring-shaped structure that locks with a limiting member. The distal end of each track 2100 has a grooved fixed pulley that can engage with the track 2100 as a distal limiting member 2101, and the proximal end has a hooked end cap that can engage with the track 2100 as a proximal limiting member 2102. The suspension... After passing upward through the grooved fixed pulley of the distal limiting member 2101, component 22 extends horizontally and connects to the bullnose-shaped structure of the sliding locking member 2110. When the sliding locking member 2110 slides to the distal limit position, it will be blocked by the grooved pulley. At this time, the three-dimensional protective leg warming electric blanket body 1 is in the lowered use state. When the sliding locking member 2110 slides to the proximal limit position, the ring structure on the sliding locking member 2110 can lock with the hook end cap. At this time, the three-dimensional protective leg warming electric blanket body 1 is in the raised and suspended state.

[0051] The electric blanket body 1 is connected to the heating mat 3 via interlocking power supply connectors 31.

[0052] Through the above-mentioned solution of this utility model, the electric blanket can adapt to the physiological curve of the lower limbs of the human body in a sitting position. Under the action of the electric blanket's own weight and softness, the heating surface can fit more closely to the human body. Compared with a flat electric blanket, the contact area between the heating surface and the human body is increased by 25%. After continuous use for 20 minutes at the same power, the body surface temperature increases by 1.2-2.7℃, and the heat loss is reduced by 21% after continuous use for 1 hour at the same power. It realizes the quick switching between lifting and lowering the three-dimensional protective leg warming electric blanket. When not in use, the three-dimensional protective leg warming electric blanket does not need to be placed separately and will not fall to the ground. With just a simple movement and slight adjustment, the three-dimensional protective leg warming electric blanket can be reset to warm up, increasing the convenience of use.

[0053] Example 2 (Small "T" shaped unfolded planar form + matrix adjustable suspension system)

[0054] Please see Figure 3 , Figure 7 A three-dimensional protective leg-warming electric blanket, which differs from Embodiment 1 in that:

[0055] The three-dimensional enclosed leg warming electric blanket body 1 unfolds into a small "T" shaped irregular planar shape with topological optimization design, and its longitudinal main sheet does not have an end cover 105 for covering the feet.

[0056] The suspension system 2 achieves the switching between the raised and lowered usage states of the three-dimensional enveloping leg warming electric blanket body 1 through matrix adjustment. Specifically, the two distal limiting parts 211 in the base assembly 21 are grooved fixed pulleys, symmetrically fixed to the bottom of the table away from the human body with self-tapping screws, with a spacing approximately equal to the width of the three-dimensional enveloping electric blanket body 1. The proximal limiting part 212 is an adhesive hook, symmetrically fixed to the bottom of the table near the human body, with the four limiting parts arranged in a rectangle. The movable locking part 221 at the upper end of the suspension assembly 22 is a pull ring. The suspension assembly 22 extends horizontally after passing the grooved fixed pulley. When the pull ring is blocked by the grooved fixed pulley, the three-dimensional enveloping leg warming electric blanket body 1 is in the lowered usage state. When the pull ring moves to the adhesive hook end, it can lock with the adhesive hook, at which point the three-dimensional enveloping leg warming electric blanket body 1 is in the raised and suspended state.

[0057] Example 3 ("convex" shaped irregular planar form + split-type adjustable suspension system)

[0058] Please see Figure 4 , Figure 6 A three-dimensional protective leg-warming electric blanket, which differs from Embodiment 1 and Embodiment 2 in that:

[0059] The three-dimensional enclosed leg warming electric blanket body 1 has a topologically optimized irregular planar shape in the unfolded state, with a central square area and three wings on the top, left and right. The central square area is the front covering part 102, the two wings on the sides are the left protective wing part 103 and the right protective wing part 104 respectively, and the upper wing part is the upper covering part 101.

[0060] The first set of detachable connectors 111 provided on the outer layer 11 is located at the corresponding edge where the upper cover 101 and the left wing 103 are to be connected, and the second set of detachable connectors 112 is located at the corresponding edge where the upper cover 101 and the right wing 104 are to be connected.

[0061] The suspension adjustment system 2 achieves switching between the raised suspension state and the lowered use state of the three-dimensional enclosed leg warming electric blanket body 1 through a split-adjustment mechanism. Specifically, the base assembly 21 is an adhesive hook fixed to the bottom of the table, and the adhesive hook is equipped with a hook 231. The upper end of the suspension assembly 22 is equipped with a pull ring 232. By adjusting the connection and separation of the hook 231 and the pull ring 231, the three-dimensional enclosed leg warming electric blanket body 1 can be switched between the raised suspension state and the lowered use state.

[0062] Example 4 (Irregular planar shape in the shape of a cross)

[0063] Please see Figure 5 A three-dimensional protective leg-warming electric blanket, which differs from Embodiments 1, 2, and 3 in that:

[0064] The three-dimensional enclosed leg-warming electric blanket body 1 unfolds into a topologically optimized irregular planar shape with a "+" shape, having a central square area and four wings: upper, lower, left, and right. The central square area is the front covering part 102, and the two wings are the left protective wing part 103 and the right protective wing part 104, respectively. The upper wing part is the upper covering part 101, and the lower wing part is the end covering part 105. The first set of detachable connectors 111 on the outer layer 11 is located at the corresponding edge where the upper covering part 101 and the left protective wing part 103 are pre-connected, and the second set of detachable connectors 112 is located at the corresponding edge where the upper covering part 101 and the right protective wing part 104 are pre-connected.

[0065] The suspension adjustment system 2 is a non-essential structure. Suspension systems with different adjustment methods can be used in conjunction with three-dimensional enclosure structures with different unfolded planar shapes.

[0066] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
