Abstract

The utility model provides a four-grade heat regulating control switch for an electric heating mattress, which comprises two five-grade two-way slide switches which are connected together in series and are linked via a handle. One of the assemblies is a series-parallel converting assembly, and the other is power control switch assembly; the grades of the two assemblies completely correspond, and the grades are a grade for closure, a low grade for heat preservation, a high grade for heat preservation, a low grade for temperature rise, and a high grade for temperature rise. By the regulation of the grades, the fast temperature rise and the temperature regulation of multiple grades for long-time heat preservation of the electric heating mattress can be realized, and the heating temperature of resistance wires can be effectively controlled to fit different environmental temperatures and difference requirements of the temperature of the electric heating mattress.

Description

Under blanket four-shift temp.-regulating control switch

The utility model relates to a kind of control switch, particularly a kind of under blanket four-shift temp.-regulating control switch.

At present, though the under blanket kind of selling on the market is a lot, its version is basic identical, especially shows on the switch of its use.Existing under blanket switch can be divided into two kinds of break-make and temperature-adjusting types substantially, though the break-make type is simple in structure, cost is low, because its function is too single, has been in the status that is eliminated; Though the temperature-adjusting type switch can satisfy the needs of people to the under blanket temperature control to a certain extent, but its majority only can provide high and low temperature two kinds of different temperatures, and the temperature adjustment amplitude is little, can not adapt to people under blanket is rapidly heated, multinomial more actual demand such as insulation when long.

The purpose of this utility model provides a kind of simple in structure, can be rapidly heated, again the perfect electric warming mattress of heat insulation function four-shift temp.-regulating control switch for a long time.

The purpose of this utility model is achieved in that it comprises that two five grades two-way slide switch assemblies that are serially connected each other and linked by a handle constitute; One is the connection in series-parallel transition components in two assemblies, and 2 * 7 contacts and two double-contact slide plate E, F are arranged; Another is the power control switching assembly, and 2 * 5 contacts and two double-contact slide plate G, H are arranged; The gear of two assemblies is corresponding fully, according to the sense of current be followed successively by close shelves, insulation is low-grade, insulation is high-grade, heat up low-grade and heat up high-grade;

The slide plate G of power control switching assembly b links to each other with an end of power supply, 2,4 contacts of assembly b link to each other, 3,5 contacts link to each other, be connected with rectifier diode D between contact 2,4 and the contact 3,5, contact 3,5 directly links to each other with the contact 4,5 of assembly a, is serially connected with rectifier diode D between the contact 2,4 of assembly b and the contact 4,5 of assembly a;

2,3 contacts of connection in series-parallel transition components a and under blanket resistance wire B end links to each other with 9 contacts 8,, 6,7 contacts link to each other with the centre cap A of under blanket resistance wire, and 10,11 contacts are connected with the C end of under blanket resistance wire, the slide plate H of assembly b and the other end of power supply.

The utility model is by the break-make control to two five grades two-way slide switch assemblies, can realize that " heat up high ", " it is low to heat up ", " insulation is high ", " being incubated low " fourth gear temperature of under blanket control, thereby adapt to the requirement of different ambient temperatures and different people the under blanket temperature.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.

Fig. 1 is a circuit diagram of the present utility model.

Fig. 2 is a schematic appearance of the present utility model.

As shown in the figure, the utility model comprises that two five grades two-way slide switch assemblies that are serially connected each other and linked by a handle constitute; One is connection in series-parallel transition components a in two assemblies, and 2 * 7 contacts and two double-contact slide plate E, F are arranged; Another is power control switching assembly b, and 2 * 5 contacts and two double-contact slide plate G, H are arranged; The gear of two assemblies is corresponding fully, according to the sense of current be followed successively by close shelves, insulation is low-grade, insulation is high-grade, heat up low-grade and heat up high-grade; Be provided with centre cap with the resistance wire of the matching used under blanket of the utility model.Concrete annexation of the present utility model is as follows: the slide plate G of power control switching assembly b links to each other with an end of power supply, 2,4 contacts of assembly b link to each other, 3,5 contacts link to each other, be connected with rectifier diode D between contact 2,4 and the contact 3,5, contact 3,5 directly links to each other with the contact 4,5 of assembly a, is serially connected with rectifier diode D between the contact 2,4 of assembly b and the contact 4,5 of assembly a;

2,3 contacts of connection in series-parallel transition components a and under blanket resistance wire B end links to each other with 9 contacts 3,, 6,7 contacts link to each other with the centre cap A of under blanket resistance wire, and 10,11 contacts are connected with the C end of under blanket resistance wire, the slide plate H of assembly b and the other end of power supply.

Show operating state of the present utility model for convenience, the contact 6,7,8,9 of assembly b links to each other with current-limiting resistance R with light-emitting diode respectively.

When using the utility model, its power end and civil power are connected, the centre cap of its A termination under blanket resistance wire, B, C are held respectively the two ends with the under blanket resistance wire.Each grade working condition is as follows:

" heat up high " shelves: two 5 grades of two-way slide switch assembly a, b slide to " it is high to heat up " position, and this moment, two sections resistance wires were state in parallel, and resistance is little, is not connected in series rectifier diode D, directly connects utility grid, this moment power maximum (100%), it is the fastest to heat up.

" it is low to heat up " shelves: two 5 grades of two-way slide switch assembly a, b slide to " it is low to heat up " position, and this moment, two sections resistance wires be state in parallel still, and resistance is little, but with utility grid between be connected in series rectifier diode D, power (being about 70%) greatly at this moment, it is slower to heat up.(cold especially in room temperature, as to wish when warm that these shelves can be as " insulation " the most high-grade use).

" insulation is high " shelves: two 5 grades of two-way slide switch assembly a, b slide to " insulation is high " position, and this moment, two sections resistance wires were series connection, and resistance is big, and be not connected in series rectifier diode D, directly connect utility grid, this moment, power less (being about 25%) can keep warm slightly temperature for a long time.

" be incubated " shelves low: two 5 grades of two-way slide switches slide to " be incubated low " position, and this moment, two sections resistance wires were series connection, and resistance is big, and serial connection rectifier diode D, and power minimum (being about 17%) can make under blanket keep little warm temperature for a long time at this moment.
