Abstract

The utility model discloses an electric-heating cotton quilt, which comprises a pad of cotton batting (1) and a quilt cover. The utility model is characterized in that heating resistances (2) with insulating tubes is additionally provided in the inner side of the cotton batting (1) and the heating resistances (2) are sewed in the inner side of the cotton batting and are connected with 220V AC cross-coupling insulating transformer (6) through a temperature detect switch (3), wires (4) and an adjustable thermo resistances (5),,and the insulating transformer is connected with the power source. The utility model has the advantages that the utility model can keep the quilt well dried in a humid environment, and has a better health effect on rheumatism and other diseases, and reduces heat loss, cotton consumption and the weight of cotton batting, therefore the user can sleep without compression, moreover, the quilt is easy to carry and operate.

Description

electric heating quilt

technical field

The utility model relates to a bedding, in particular to an electric heating quilt.

Background technique

As we all know, quilts are necessary heat preservation tools for people to sleep. Traditional heat preservation quilts are composed of quilt covers and cotton wool inside. The quilts with this structure are just a cover to prevent heat conduction from being too fast and reduce the consumption of a large amount of heat energy of the human body. The heat emitted by the human body is kept in the quilt as much as possible to make the human body feel comfortable. The quilt with this structure cannot emit heat by itself. At first, it needs to consume the heat of the human body to create a warm small environment, so people just fall asleep. Sometimes I feel that the quilt is cold and very uncomfortable, and more human energy is consumed to keep the quilt warm during sleep, especially in a colder environment, thicker cotton wool is needed to keep the heat conduction slow, so that people sleep There is an uncomfortable pressure.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the prior art, to provide a kind of self-heating to maintain a warm inner environment in the quilt, so that the human body can sleep comfortably and reduce the heat loss of the human body. The purpose of the utility model is through the following technology The utility model includes cotton wool and a quilt cover, and is characterized in that: a heating resistance wire with an insulating tube is added inside the cotton wool; It is connected with the 220V AC mutual coupling isolation transformer, and the isolation transformer is connected with the power supply.

If necessary, one layer of batting can be wrapped outside said batting, and the heating resistance thread is sewn on the batting.

In consideration of observing the working condition of the electric heating quilt, the utility model also adds an LED lamp, and under the normal working condition, the LED remains on.

The adjustable variable temperature resistance of the utility model generally only works below 37°C, and when the temperature reaches 37°C, it will automatically disconnect and stop working to ensure safety.

From the foregoing, it can be seen that the purpose of this utility model can be achieved.

Compared with the prior art, the utility model has the following advantages: 1. The human body will not have a cold feeling when just sleeping, and the quilt can be kept dry in a humid environment, and has better health care effects on diseases such as rheumatism. 2. It can greatly reduce the heat loss of the human body. 3. It can greatly reduce the amount of cotton and the weight of cotton wool, so that the human body does not feel oppressed when sleeping. 4. The quilt is easy to carry and use.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

The utility model will be further described below in conjunction with the embodiments according to the accompanying drawings.

As shown in Figure 1, the utility model includes cotton wool 1 and a quilt cover, and is characterized in that: a heating resistance wire 2 with an insulating tube is added inside the cotton wool, the heating resistance wire is sewn on the inner side of the cotton wool, and the heating wire passes through a temperature control switch 3 and a wire 4 The adjustable variable temperature resistance 5 is connected with the 220V AC mutual coupling isolation transformer 6, and the isolation transformer is connected with the power supply. Considering that the service life of the cotton wool is longer, the present embodiment wraps a layer of batting outside said cotton wool, and the heating resistor is sewn on the batting. Simultaneously, in consideration of better displaying the working conditions, an LED indicator light 7 is added in this embodiment, and in the normal working state, the LED light remains on.

Claims (3)
