Description

Technical Field

[0001] This utility model belongs to the field of mattress technology, specifically relating to a length-zone heating device and a length-zone heating mattress. Background Technology

[0002] Some mattresses have heating functions. The heating devices of existing mattresses generally use uniformly distributed resistance wires or carbon fiber heating strips, resulting in a basically uniform temperature in all parts, which cannot meet the different temperature requirements of different parts (such as the lower back requiring a relatively higher temperature and the back requiring a relatively lower temperature).

[0003] Furthermore, most existing mattress heating devices use a single heating strip (not considering left and right partitions), with the heating heads bent to distribute evenly. If the heating strip breaks in any part, the entire heating device will fail. In addition, to achieve the bending effect, the heating strip uses a circular cross-section, which has a lower heat utilization rate and is prone to causing discomfort.

[0004] Therefore, there is room for improvement in the zoned heating structure of mattresses. Summary of the Invention

[0005] This invention addresses the shortcomings of existing mattress zone heating structures by providing a length-zone heating device for mattresses to meet the different temperature requirements of different areas. This invention also provides a length-zone heated mattress using this device. Furthermore, it avoids the entire heating device failing due to breakage at one point; improves heat utilization; and reduces discomfort caused by the heating elements.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a length-division heating device, the length-division heating device comprising:

[0010] The encapsulation material encapsulates at least the heating element and the internal wiring harness, forming an integrated structure.

[0011] The heating body has at least two heating parts corresponding to the foot area, calf area, thigh area, buttock area and waist area of ​​the human body, and the heating power per unit area of ​​the two heating parts is different.

[0012] The length-division heating device of this utility model has at least two heating parts corresponding to the foot area, calf area, thigh area, buttock area and waist area of ​​the human body. The heating power per unit area of ​​the two heating parts is different, and the heating power per unit area of ​​each heating part in the height direction of the human body is different, so as to meet the needs of different parts in the height direction of the human body and is more reasonable.

[0013] As an improvement, the heating element includes a substrate and multiple heating strips distributed along the length of the mattress on the substrate. All heating strips have equal power, but the density of the heating strips in at least one of the foot, calf, thigh, buttock, and waist heating areas differs from that in the other areas. This difference in heating power per unit area is achieved through the density of the heating strips, making it simple and convenient.

[0014] As an improvement, the heating body has five heating sections corresponding to the foot area, calf area, thigh area, buttock area and waist area of ​​the human body. The density of the heating strips in the foot area and waist area is greater than that in the calf area, thigh area and buttock area.

[0015] As an improvement, all heating elements use the same heating strips, with the length of the heating strips aligned with the width of the mattress. The spacing between adjacent heating strips in each heating element varies, resulting in different densities.

[0016] As an improvement, the width of the heating strip is 2-4cm, and the spacing between adjacent heating strips in the same heating section is between 2-5cm.

[0017] As an improvement, the foot and calf heating sections share a single wire bundle. The total number of heating strips in these two sections is an even number. These heating strips are divided into m groups connected in series, with the heating strips in each group connected in parallel, where m ≥ 2; and / or,

[0018] The heating sections for the thigh, buttock, and waist areas share a single wire bundle. The total number of heating strips in these three sections is an even number. These heating strips are divided into n groups connected in series, with the heating strips in each of the n groups connected in parallel, where n ≥ 2. As an improvement, the length-zoned heating device also includes a temperature sensor connected to the controller.

[0019] As an improvement, the length-zone heating device also includes a controller and a sleep sensor strip connected to the controller. The sleep sensor strip is fixed in a retaining sleeve on the encapsulation material, and the sleep sensor strip detects the human body; and / or,

[0020] The switch corresponds to the finger area.

[0021] A length-zone heated mattress, wherein the length-zone heated mattress includes the aforementioned length-zone heating device.

[0023] Support layer;

[0024] Comfort layer;

[0025] Length-divided heating device;

[0026] Quilted layer;

[0028] The quilted layer includes a top quilted layer and a bottom quilted layer, and the length-zoned heating device is fixed on the inner surface of the top quilted layer.

[0029] The beneficial effects of this utility model of length-zone heating device and length-zone heating mattress are: the heating power per unit area of ​​each heating part corresponding to the height of the human body is different, thereby adapting to the needs of different parts of the human body in the height direction, which is more reasonable.

The heating power per unit area of ​​the two heating parts is different, and the heating power per unit area of ​​each heating part in the height direction of the human body is different, so as to meet the needs of different parts in the height direction of the human body and is more reasonable.

[0053] Example 1

[0054] See Figures 1 to 5 The length-zone heated mattress of this utility model embodiment includes a length-zone heating device 01, which includes:

[0055] Heating body 1;

[0056] Switch 2;

[0057] Internal wiring harness 3 connects heating body 1 and switch 2;

[0058] The encapsulation material 4 encapsulates at least the heating body 1 and the internal wiring harness 3, forming an integrated structure;

[0059] The heating body 1 has at least two heating parts corresponding to the foot area, calf area, thigh area, buttock area and waist area of ​​the human body, and the heating power per unit area of ​​the two heating parts is different.

[0060] In this embodiment, the length-zone heated mattress also includes:

[0061] Support layer 7;

[0062] Comfort layer 8;

[0063] Length partition heating device 01;

[0064] Quilted layer 9;

[0065] Among them, the support layer 7, the comfort layer 8 and the length zone heating device 01 are distributed from bottom to top, and the quilted layer 9 wraps the support layer 7, the comfort layer 8 and the length zone heating device 01 inside;

[0066] The quilted layer 9 includes a top quilted layer 91 and a bottom quilted layer 92, and a length-divided heating device 01 is fixed to the inner surface of the top quilted layer 91. The quilted layer 9 also includes four sides.

[0067] In this embodiment, the heating body 1 includes a substrate and multiple heating strips 11 distributed along the length of the mattress on the substrate. Each heating strip 11 has the same power, and the density of heating strips 11 in at least one of the foot area, calf area, thigh area, buttock area, and waist area heating sections 17 is different from that in other areas. The different heating power per unit area is achieved by varying the density of the heating strips 11, which is simple and convenient.

[0068] In this embodiment, the heating body 1 has five heating parts: foot heating part 13, calf heating part 14, thigh heating part 15, buttock heating part 16, and waist heating part 17. The density of the heating strips 11 in the foot heating part 13 and waist heating part 17 is greater than that in the calf heating part 14, thigh heating part 15, and buttock heating part 16.

[0069] In this embodiment, all heating elements use the same heating strip 11. The length direction of the heating strip 11 is consistent with the width direction of the mattress. The spacing between adjacent heating strips 11 in each heating element is different, resulting in different densities.

[0070] In this embodiment, the width of the heating strip 11 is 2-4 cm, and the spacing between adjacent heating strips 11 in the same heating section is between 2-5 cm. More specifically, the width of the heating strips 11 in the foot heating section 13 and the waist heating section 17 is 3 cm, and the spacing is 2.25 cm; the width of the heating strips 11 in the calf heating section 14, the thigh heating section 15, and the buttock heating section 16 is 3 cm, and the spacing is 4.5 cm.

[0071] In this embodiment, the foot heating section 13 and the calf heating section 14 share the same first wiring harness. The total number of heating strips 11 in these two heating sections is an even number. The heating strips 11 in these two heating sections are divided into m groups connected in series, and the heating strips 11 in the m groups are connected in parallel, where m ≥ 2. Specifically, m = 2, and the number of heating strips 11 in each of the two groups is 3.

[0072] In this embodiment, the length-zone heating device 01 further includes a controller 5. The foot area heating unit 13 and the calf area heating unit 14 are connected to the controller 5 via the first wiring harness. The controller 5 is connected to a power cord 51.

[0073] In this embodiment, the thigh heating section 15, the buttock heating section 16, and the waist heating section 17 share a second wiring harness. The total number of heating strips 11 in these three heating sections is an even number. The heating strips 11 in these three heating sections are divided into n groups connected in series, and the heating strips 11 in the n groups are connected in parallel, where n ≥ 2. Specifically, n = 2, and the number of heating strips 11 in each of the two groups is 7. The thigh heating section 15, the buttock heating section 16, and the waist heating section 17 are connected to the controller 5 through this second wiring harness. Since the number of heating strips 11 in the foot heating section 13, the calf heating section 14, the thigh heating section 15, the buttock heating section 16, and the waist heating section 17 is different (one has 6, and the other has 14), the power of all 20 heating strips 11 can be made consistent by setting resistors or other methods (when no individual adjustment is performed). In other embodiments, all heating strips on the single-person side can be divided into several groups (preferably two groups), each group of heating strips is connected to a wire bundle, and each group of heating strips is further divided into several subgroups connected in series (preferably two groups), each subgroup including several heating strips connected in parallel with the same number of elements. In this way, the power of all heating strips 11 on the single-person side can be equal without the need to use additional resistors or other methods.

[0074] In this embodiment, a single heating strip 11 extends along the width of the mattress, and high-temperature resistant silicone wires 12 are connected to both ends of the heating strip 11. The high-temperature resistant silicone wires 12 at both ends of the heating strip 11 are unidirectional wires. The internal wiring harness 3 also uses high-temperature resistant wires, which are bidirectional wires.

[0075] In this embodiment, the length-zone heating device 01 further includes a sleep sensing strip 62 connected to the controller 5. The sleep sensing strip 62 is fixed in a sensing strip fixing sleeve 61 on the encapsulation material 4, and the sleep sensing strip 62 detects the human body. The sensing strip fixing sleeve 61 is located above the encapsulation material 4. The sleep sensing strip 62 also detects human sleep data, and the controller 5 adjusts the power output of the length-zone heating device 01 according to the received human sleep data. In other embodiments, the controller 5 may not be provided, and the device may be turned on or off simply by using the switch 2.

[0076] In this embodiment, the length-zone heating device 01 also includes a controller 5 and a temperature sensor connected to the controller 5. The temperature sensor can detect the ambient temperature of the bedroom and / or the mattress temperature, providing data support for the automatic control of the controller 5.

[0077] In this embodiment, switch 2 corresponds to the finger area and can be used for one-button start / stop, facilitating user operation. Switch 2 can be a button type or a knob type. A knob type switch 2 can achieve power connection and power adjustment by rotation.

[0078] In this embodiment, the length-zone heating mattress includes two length-zone heating devices 01 distributed on the left and right, and the two length-zone heating devices 01 share the same controller 5.

[0079] In this embodiment, all heating strips 11 are flat, which improves the heating effect and makes it less likely to cause a foreign body sensation.

[0080] In this embodiment, at least some of the heating bars 11 are connected in parallel. Specifically, a hybrid series-parallel connection (connected to the same internal wiring harness 3) is used. In other embodiments, all of them may be connected in parallel.

[0081] In this embodiment, the heating material of the heating strip 11 can be graphene, carbon nanotubes, resistance wire, etc.

[0082] The beneficial effects of the length-zone heating mattress of Embodiment 1 of this utility model are as follows: the heating power per unit area of ​​each heating part corresponding to the height of the human body in the length-zone heating device 01 is different, thereby adapting to the needs of different parts of the human body in the height direction, which is more reasonable; the length-zone heating device 01 achieves different heating power per unit area through different densities of heating strips 11, and the structure is simple; a switch 2 is provided, which can be used to turn the power on and off and to start and stop the heating; at least some heating strips 11 are connected in parallel, and the damage of some heating strips 11 in parallel does not affect the operation of other heating strips 11, avoiding the situation in the prior art where the failure of one part of the fully series heating component causes the entire heating device to fail; a sleep sensing strip 62 is provided, which detects the human body and can realize automatic heating; a controller 5 is provided, and the sleep sensing strip 62 also detects human sleep data, and the controller 5 adjusts the power output of the length-zone heating device 01 according to the received human sleep data.
