Description

Technical Field

[0001] This utility model belongs to the field of mattresses and accessories, and specifically relates to a heating device for mattresses and a mattress. Background Technology

[0002] Traditional heating devices often use linear or grid-like fixed wiring, which usually has a multi-layered structure. The structure is relatively complex, the wiring is messy and disorderly, and it is easy for the wiring to cross and interfere with each other. During assembly, the connecting wires are also easy to pull, which can cause microscopic deformation at the terminal crimping point, easily leading to loose connection and thus affecting reliability. Utility Model Content

[0003] To address the problems of unreasonable wiring and weak connections in existing mattress heating devices, this utility model provides a mattress heating device and mattress. By rationally wiring the device, the cross-connection of wires is effectively reduced, and by setting wire clamping blocks on the heat-melting cotton layer, the wiring is ensured to be firm and reliable.

[0004] The technical solution adopted by this utility model is as follows: A heating device for a mattress, comprising:

[0005] The inner sleeve can be fitted over the surface of the bed core;

[0006] The heating control assembly includes at least two sets, each set comprising:

[0007] A heating element is attached to the top of the inner sleeve;

[0008] A control switch is located on the side of the inner sleeve;

[0009] A first connecting harness is disposed on the inner sleeve, and the first connecting harness connects the heating element and the control switch;

[0010] A hot-melt cotton layer is horizontally disposed at the bottom of the inner sleeve. A second connecting wire harness and a wire clamping block are disposed at the hot-melt cotton layer. The wire clamping block is used to constrain the first connecting wire harness and the second connecting wire harness.

[0011] An external power cord, connected to the second connecting harness, is used to connect to an external power source;

[0012] The two heating control components are connected by the second connecting harness.

[0013] In this application, each heating control component can achieve independent control and heating, which facilitates monitoring, maintenance and replacement of components. The first and second connecting wire harnesses are constrained by wire clamps set on the hot melt cotton layer to prevent pulling on the wiring and ensure that the wiring is firm and reliable.

[0014] Furthermore, the first connecting harness includes a first connecting segment, a second connecting segment, and a third connecting segment. The first connecting segment is connected to the heating element, the third connecting segment is connected to the control switch, and the second connecting segment connects the first and third connecting segments. The first and second connecting segments, as well as the second and third connecting segments, are connected via waterproof male and female connectors. The first connecting harness is divided into three parts, facilitating separate assembly and reconnection for quick disassembly and reassembly.

[0015] Furthermore, the first connecting segment extends downward along the inner top surface and inner side surface of the inner sleeve, the second connecting segment extends horizontally along the inner side surface of the inner sleeve, and the third connecting segment extends downward along the control switch. In this arrangement, each connecting segment can achieve a reasonable layout and smooth connection, without large drooping lines, effectively avoiding interference between connecting lines and messy wiring.

[0016] Furthermore, the heating element is fixed to the inner surface of the inner sleeve by a zipper stitch. This arrangement securely positions the heating element at the top of the inner sleeve, effectively preventing displacement.

[0017] Furthermore, the second connecting harness includes a fourth connecting segment, a fifth connecting segment, and a sixth connecting segment. The fourth connecting segment is connected to the control switch, the sixth connecting segment is located on the lower surface of the hot-melt cotton layer, and the fifth connecting segment connects the fourth and sixth connecting segments.

The second connecting harness is divided into three parts, enabling quick assembly and disassembly and efficient wiring.

[0018] Furthermore, the wire clamping block is provided with a threading hole through which the second connecting segment and the fifth connecting segment pass. The wire clamping block constrains the second connecting segment and the fifth connecting segment, which are respectively the middle parts of the first connecting wire harness and the second connecting wire harness, ensuring that the first connecting wire harness and the second connecting wire harness are not easily displaced.

[0019] Furthermore, the inner sleeve has a sponge layer and an edge sponge on its inner side, and the hot-melt cotton layer is disposed on the sponge layer. The upper and lower surfaces of the edge sponge are provided with grooves, through which the first and second connecting wire harnesses can pass. The edge sponge provides support, the sponge layer provides connection, and the hot-melt cotton layer is disposed on the surface of the sponge layer. The two are tightly adhered and glued together to form a reliable connection.

[0020] Furthermore, the mattress heating device also includes an outer cover, which is disposed outside the inner cover, and the control switch is disposed on the outer cover. The outer cover surrounds the inner cover, and the control switch is disposed on the outer cover, making it convenient for the user to observe and control, and also facilitating wiring.

[0021] Furthermore, the inner surface of the inner sleeve is provided with multiple elastic bands, and the first connecting wire harness runs along the inner surface of the inner sleeve and passes through the elastic bands. The elastic bands ensure a reliable connection of the first connecting wire harness by applying tension.

[0022] A mattress includes a mattress core and a heating device disposed on the mattress core, wherein the heating device is the aforementioned mattress heating device.

[0023] The beneficial effects of this utility model are as follows: This application discloses a heating device for a mattress and a mattress. Each heating control component can achieve independent control and heating, facilitating monitoring, maintenance, and component replacement. A wire clamping block placed on the heat-melting cotton layer constrains the first and second connecting wire harnesses to prevent pulling on the wiring, ensuring a secure and reliable connection. Furthermore, the segmented design of the first and second connecting wire harnesses simplifies the assembly and disassembly process, facilitates assembly and disassembly, and forms a reliable connection.
