Description

Multi-partition temperature control electric blanket

Technical Field

The invention relates to the technical field of electric blankets and physical therapy apparatuses, in particular to a multi-partition temperature control electric blanket.

Background

Currently, it is common to know electric blankets or physiotherapy apparatuses for treating physical discomfort by heating local areas. The traditional electric blanket is simple in use and temperature control, and often causes overall discomfort to users who want to locally heat neck, shoulder, waist and feet. Because a human body often has a region which feels cold and the feeling difference between the whole body feeling and the region is very large, the integral heating often causes that a user can only select one of integral partial cold and integral overheating, and the absolute comfort point is difficult to reach. The traditional physiotherapy instrument is generally used independently, and has high price and poor comfort; the independent function is also beneficial to achieving the overall comfortable effect.

Disclosure of Invention

The invention aims to solve the technical problems that the integral heating of an electric blanket is difficult to achieve the optimal comfortable point and the physical therapy function of a specific area is difficult to realize. The multi-partition temperature control electric blanket has the characteristics of novel design, low manufacturing cost and strong practicability.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a multi-partition temperature control electric blanket comprises a plurality of independent function partitions, wherein each independent function partition is provided with an independent shape, heating power and control unit according to the comfortable heating requirement of a human body; and each independent functional partition independently adjusts the heating frequency and the heating power according to a prestored instruction, sensor information or a manual input instruction, so that the most comfortable heating experience is realized. The improvement can be assisted by heating the individual regions for users who have local discomfort such as neck, shoulder, waist, and foot.

Further, independent function partitions on the electric blanket are in a tiled arrangement.

The electric blanket is divided into regions according to functional parts of a human body, functional regions of upper limbs, lower limbs and feet of the human body are distributed with required highest heating power according to highest heating characteristics of the regions, wherein feet of women are prone to chilliness in winter, the highest heating temperature of the region is higher than those of other regions, each independent functional region is controlled by an independent control unit, and a master control system instructs each independent control unit to work. The user can adjust the operating parameters of any one of the individual functional zones at any time or individually turn on or off certain zones to achieve an optimal heating state.

Further, the independent function partitions on the electric blanket are arranged in an overlapping mode.

The independent function subareas on the electric blanket are arranged in a laminating way, and the neck-shoulder reinforcing layer, the waist reinforcing layer, the foot reinforcing layer and other independent function subareas can be laminated on the basic heating layer. The basic heating layer is used for realizing basic heating or preheating, the laminated area mainly realizes power enhancement of a special area or independent opening and closing, various optimized combination schemes can be realized through a superposition control mode, and a certain energy-saving effect can be realized. When the electric blanket works, a user can select whether to turn on the basic heating layer and turn on or off each independent strengthening area so as to adjust the comfortable state.

Further, the control unit of each independent function partition adopts one or more control modes of voltage control, current control and relay switch control.

Each individual partition control unit selection may select a control type according to a use state. The electric blanket which is arranged in a layered and partitioned way is more suitable for using a relay switch control mode; the mode is simple and reliable, the cost is low, and various heating intensity choices can be combined according to the characteristic of independent function zone stacking. The electric blanket with the partitions is laid in a tiled mode, and when the partitions are few, the electric blanket is suitable for being realized by using a voltage control module; the system is simpler, and the temperature control is more flexible. The electric blanket with the partitions laid in a tiled mode is suitable for being realized by using the current control module when the partitions are more, the highest current used by each independent function partition of the system is not large, and the scheme for controlling the current to realize adjustment by using the charge pump has the advantages of reasonable cost, flexible temperature control and small system size.

Furthermore, the electric blanket is divided into a plurality of independent function partitions according to the use requirement, part of the function partitions can share one control unit, and the whole electric blanket at least comprises two independent control units.

After the independent function partition of the electric blanket is selected, certain areas with similar use states can be combined to use one control unit to save cost and improve the reliability of the system, the conditions that the neck-shoulder function area and the foot function area need to be opened are similar, and the control unit can be combined on the premise of deleting one flexibility.

Further, the heating part of the electric blanket adopts any one of a direct current mode or an alternating current mode.

The multi-partition temperature control electric blanket using the direct current heating system has the advantages that any one of a flat arrangement and an overlapping arrangement can be selected as a partition mode, any one of voltage control, current control and relay switch control can be selected as a control mode, and the combination scheme is diversified.

The multi-zone temperature control electric blanket using the alternating current heating system is difficult to use a current control mode, and is difficult to achieve accurate temperature regulation by using a voltage control mode, and the mode uses a relay switch control and independent function zone overlapping arrangement scheme.

Further, the heating part of the electric blanket adopts a mode of mixing direct current and alternating current.

A multi-zone temperature controlled electric blanket using a hybrid ac and dc heating system is a solution with overlapping placement of independent functional zones. The alternating current heating mode is low in cost and high in power and is suitable for serving as a basic heating layer, but the safety of the alternating current heating mode is poor, so that the alternating current heating system is recommended to be turned off after preheating is completed and is replaced by the direct current heating system on the upper layer, the direct current heating system is matched with each independent function partition, although the heating power is low, the temperature maintenance capability is still available, and the adaptability adjustment is more flexible.

Compared with the prior art, the invention has the following advantages:

1. the user can adjust the temperature rise and fall and the intervention time of any one area according to the feeling, and the optimal comfortable point can be quickly reached.

2. The improvement can be also assisted by heating the individual areas for users with local discomfort such as neck, shoulder, waist, feet, etc.

3. Each functional area can adjust the working state thereof to meet the optimal comfort requirement of a user in a manual intervention mode.

4. The user may use the recommended input mode or may individually adjust the temperature of any one zone to be most comfortable.

5. The mobile phone can be used as a controller and has basic conditions for being matched with other health management software. The mobile phone can be used as a controller, and control programs and the like can be prestored in the mobile phone, so that the mobile phone can be updated and adjusted in real time, and the manufacturing cost of the system can be effectively reduced.

6. The multi-zone temperature control mode can effectively coordinate the relationship between cost and comfort and provide more selection possibilities.
