Abstract

The utility model discloses a massaging cushion internally provided with a double helix electric wire. The massaging cushion comprises a flexible cushion body made by heat conducting material; an electric control device and a massaging device are arranged on the cushion body; a double helix electric wire is arranged in the cushion body, and the double helix electric wire is electrically connected with the electric control device. The double helix electric wire is fixed inside the cushion body to be used as an electric heating element, and since the double helix electric wire has excellent buckling strength, the electric wire is not easy to be deformed under pressure; in addition, the double helix electric wire can realize full line temperature control for the whole bag body, thus the overall heating evenness is facilitated.

Description

The massage cushion of built-in Double helix heating wire

Technical field

This utility model relates to a kind of electric heating massage cushion, especially a kind of massage cushion of built-in Double helix heating wire.

Background technology

Existing electric heating massage cushion, its structure comprise the flexible pad of being made by Heat Conduction Material, and electric control gear, massage machine and common electrical hot line are installed on the pad; The common electrical hot line is arranged in the pad and with electric control gear and is electrically connected, and the common electrical hot line only has heat effect.The electric heating massage cushion of said structure has the following disadvantages: 1), massage cushion adopts common heating wire as electrical heating elements, the common electrical hot line only has heat effect, and do not possess temperature automatically controlled effect, for this reason, use the massage of common electrical hot line heating to pay somebody's debt and expect repayment later the temperature control device that must dispose heater wire, so, the common electrical hot line facility is single, do not reach the effect of temperature control completely at all, also there is certain potential safety hazard: 2), pad belongs to flexible instrument, and the flexural strength of common electrical hot line is very low, the easy deformation of its pressurized, influence heats, even cause heating wire to damage.

The utility model content

The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and provide a kind of simple and reasonable for structure, employing flexural strength height, and can reach completely that the Double helix heating wire of temperature control does not have part as electrical heating is with the massage cushion of the built-in Double helix heating wire that improves safety.

The purpose of this utility model is achieved in that

A kind of massage cushion of built-in Double helix heating wire comprises the flexible pad of being made by Heat Conduction Material, and electric control gear and massage machine are installed on the pad, also is laid with the Double helix heating wire in the described pad, and the Double helix heating wire is electrically connected with electric control gear.The massage cushion of this structure, by the Double helix heating wire being arranged as electrical heating elements at the pad internal fixation, the Double helix heating wire has good flexural strength, is difficult for pressurized deformation; Moreover the Double helix heating wire can be realized the bag effect of temperature control completely, helps its integral body and adds thermal balance.

The purpose of this utility model can also adopt following technical measures to solve:

Described Double helix heating wire comprises mandrel, internal layer PTC spiral resistance wire, NTC heat-sensitive layer, outer spiral resistance wire and external insulation layer respectively by innermost layer to outermost layer.The Double helix heating wire of this structure, its mandrel play fixedly internal layer PTC spiral resistance wire effect; Internal layer PTC spiral resistance wire has ptc characteristics, that is: PTC positive temperature coefficient, and high more its resistivity of temperature is big more, can export temperature variant signal in real time; The NTC heat-sensitive layer has the NTC characteristic, that is: NTC negative temperature coefficient, and high more its resistivity of temperature is more little, can export temperature variant signal in real time equally; It is heating function that outer spiral resistance wire mainly acts on; And external insulation layer mainly is the electric insulation effect.

For helping making the whole homogeneous heating of pad, the Double helix heating wire is the shape that circumnutates and is laid in the pad equably.

Also be fixed with the location heat sink in the described pad, the Double helix heating wire is arranged on the heat sink of location.Two spiral shell heating wires can improve its heats by location heat sink heat radiation, and help the fixing of Double helix heating wire.

The beneficial effects of the utility model are:

1), the electric heating massage cushion of this structure, adopted Double helix heating wire with PTC and NTC characteristic, this Double helix heating wire also has very strong flexural strength, pressurized is difficult for deformation; Moreover the Double helix heating wire is equipped with electronic control circuit, as: controllable silicon or comparator etc., make the Double helix heating wire reach the effect of circuit temperature-controlling completely, can realize the bag effect of temperature control completely, help its integral body to be subjected to thermal balance;

2), electric heating massage cushion of the present utility model, simply the Double helix heating wire is replaced the common electrical hot line, can realize the purpose of this utility model, it is simple and reasonable for structure, its installing technology is simple and easy, and is difficult for getting loose.

The specific embodiment

As depicted in figs. 1 and 2, a kind of massage cushion of built-in Double helix heating wire, comprise the flexible pad of making by Heat Conduction Material 1, electric control gear 2 and massage machine 3 are installed on the pad 1, also be laid with Double helix heating wire 4 in the described pad 1, Double helix heating wire 4 is the shape that circumnutates and is laid in equably on the location heat sink 5 in the pad 1, and location heat sink 5 is fixed in the pad 1; Location heat sink 5 just is provided with according to design requirement, and Double helix heating wire 4 can not need to locate heat sink 5 and be directly installed in the massage cushion pad 1; Double helix heating wire 4 also is electrically connected with electric control gear 2.Described Double helix heating wire 4 comprises mandrel 401, internal layer PTC spiral resistance wire 402, NTC heat-sensitive layer 403, outer spiral resistance wire 404 and external insulation layer 405 respectively by innermost layer to outermost layer.

Described control device 2 is provided with controllable silicon 6 or comparator, and controllable silicon 6 or comparator are electrically connected with Double helix heating wire 4.

For further improving safeguard protection, can in circuit, set up protective tube, with the break-make of control entire circuit to the pad heating; Protective tube also can be to be electrically connected with Double helix heating wire 4; If Double helix heating wire 4 damages, the protective tube open circuit protection is to realize the heated protective to pad.

Said structure only is a better embodiment of the present utility model, is not this utility model is done any pro forma restriction; Technical spirit of the present utility model is: Double helix heating wire 4 is set in Massage cushion 1; Every foundation above-mentioned technical spirit of the present utility model is made any simple modification or equivalent variations, all belongs to the protection domain of technical solutions of the utility model.
