Description

Technical Field

[0001] The invention relates to the technical field of sauna blankets, in particular to a bidirectional remote-controlled sauna blanket. Background Art

[0002] Sauna can promote sweating and detoxification, which is beneficial to speed up the metabolism of the human body and help the human body to excrete toxins, and has a positive effect on people's health. When people want to take a sauna (steam bath), they usually need to go to a sauna room or a steam room, which is sometimes very inconvenient for users. Therefore, the manufacturer has designed a simple sauna blanket structure that is convenient for users to take a sauna. The existing sauna blanket is mainly composed of an upper leather pad, a lower leather pad, a heating plate, and an electric heating wire. The upper leather pad and the lower leather pad are joined together. The upper leather pad and the lower leather pad are fixed with a side of the electric heating wire and the heating plate. The sauna blanket is externally connected to a power cord and a wire. The sauna blanket is connected to a remote control through the wire. After the sauna pad is powered on, the heating plate is used to control the heating wire to heat up. When the user lies on the sauna blanket, the user's body temperature can be accelerated to achieve sweat steaming and achieve the sauna warming effect. However, the existing sauna blanket has the following shortcomings:

[0003] 1) The current sauna blanket is connected to the remote control through a wire. When the user uses the remote control, the remote control is connected to a wire and needs to drag a long wire. It is very inconvenient to use and operate the remote control, and it is also very inconvenient to store it;

[0004] 2) The sauna blanket is connected to the remote control through a wire. The wire between the remote control and the sauna blanket will be twisted and folded during long-term use, which may easily lead to wire damage, poor contact, disconnection, etc., affecting the normal use of the sauna blanket, affecting the service life of the sauna blanket, and seriously affecting the long-term use and experience of users, and also increasing after-sales costs;

[0005] 3) Existing sauna mats usually have only a single heating function and can only achieve the most basic hot compress effect, resulting in poor physical therapy and health care effects and a single function. Summary of the invention

[0049] The process of controlling the heating and light therapy of the sauna blanket by the remote control handle 2 of the present invention includes:

[0050] The user can set the heating temperature through the heating button 25 and the cooling button 26 on the remote control handle 2. When the heating button 25, the cooling button 26 and the time adjustment button 27 on the remote control handle 2 are pressed, the heating button S1 and the cooling button S2 on the remote control mainboard will send a signal to the single-chip microcomputer U3. After receiving the signal, the single-chip microcomputer U3 will send a signal to the temperature display module. At the same time, the single-chip microcomputer U3 communicates with the control mainboard 12 through the 2.4G wireless transmission module, and sends the signal for heating or cooling to the main control chip U2 of the control mainboard 12. The main control chip U2 controls the heating of the heating wire 11. At the same time, the temperature measuring probe 15 will collect the temperature of the heating wire 11 in real time and send the collected temperature to the main control chip U2 of the control mainboard 12. When the temperature of the heating wire 11 reaches the temperature set by the user, the main control chip U2 will control the heating wire 11 to stop heating, thereby realizing the physical therapy function.
