Description

Technical Field

[0001] The present invention relates to the field of electric blanket production, and further relates to a multifunctional switch structure and an electric blanket. Background Art

[0002] Electric blankets are popular among consumers as bed heating devices, providing convenient heating for people while they sleep. However, when using electric blankets, users are exposed to high temperatures, electromagnetic fields, and radiation, which can reduce their sleep quality and physical fitness. They can also experience symptoms such as dry and sore nose, puffy eyes, constipation, dizziness, memory loss, lack of energy, depression, and irritability, leading to a decline in people's nervous, reproductive, developmental, cardiac, and immune functions.

[0003] Moreover, existing electric blankets have a single function. In addition to the basic on / off function, they can only adjust different temperatures. However, due to the low temperature in winter, if the electric blanket is turned off after going to bed, people will be woken up by the cold during sleep or have a low body temperature after waking up in the morning, which is not conducive to the body's resistance to cold. If a constant temperature is used, the human body will also be exposed to electromagnetic fields and radiation and be harmed.

[0051] In this solution, through the structural design of the multi-function switch, based on the control circuit, the control circuit includes a NE556N integrated block IC and a second voltage-stabilizing diode DW2; wherein, the positive electrode of the second voltage-stabilizing diode DW2 is connected to pin 14 of the integrated block IC, pin 14 of the integrated block IC is connected to pin 4, pin 14 of the integrated block IC is connected to pin 10, pin 12 of the integrated block IC is connected to pin 8, pin 2 of the integrated block IC is connected to pin 6, and pin 7 of the integrated block IC is connected to the negative electrode of the second voltage-stabilizing diode DW2.

[0055] Among them, the power plug XP, the circuit breaker FU, the first switch SB1, the first resistor R1, the second resistor R2 and the thyristor rectifier UR are sequentially connected in series to form a closed circuit, and the first capacitor C1 and the first resistor R1 are connected in parallel, which can realize the conversion of AC high power into low-voltage DC power.

[0056] Among them, setting the power plug XP to a power plug XP with a zero-fire mark is beneficial to ensuring that there is almost no electricity and almost no radiation in the bed when the relay J is in the disconnected state.

[0057] Among them, the second capacitor C2 and the first voltage-stabilizing diode DW1 are respectively arranged in parallel with the thyristor rectifier UR, wherein the second capacitor C2 and the first voltage-stabilizing diode DW1 are respectively connected to the positive pole of the output line of the thyristor rectifier UR, providing a stable power supply line for the relay J to ensure the stability of the relay J.

[0068] As a specific implementation method for realizing the cold start function, the control circuit further includes a twelfth resistor R12, a thirteenth resistor R13, a fourteenth resistor R14, a second switch SB2, a fourth capacitor C4, a third rectifier diode D3, a fifth rectifier diode D5, a sixth rectifier diode D6 and a third light-emitting diode LED3; pins 2 and 6 of the integrated circuit IC are respectively connected to the two ends of the second wire, and a second electrical connection point is provided between the two ends of the second wire, the second electrical connection point is connected to the positive electrode pin of the fourth capacitor C4, and the negative electrode pin of the fourth capacitor C4 is connected to the 7th pin of the integrated circuit IC; the fourteenth resistor R14, the second switch SB2 and the sixth rectifier diode D6 are arranged in series in sequence, wherein the positive side of the sixth rectifier diode D6 is connected to the 5th pin of the integrated circuit IC, and the negative side of the sixth rectifier diode D6 is connected to the positive electrode of the fourth capacitor C4. pin connected; the twelfth resistor R12 is arranged in series with the fifth rectifier diode D5, wherein the positive side of the fifth rectifier diode D5 is connected to the positive pin of the fourth capacitor C4, and the negative side of the fifth rectifier diode D5 is connected to pin 1 of the integrated circuit IC; the ninth resistor R9 is arranged in series with the third light-emitting diode LED3 to form a second series branch, one end of the second series branch is connected to pin 14 of the integrated circuit IC, and the other end of the second series branch is connected to pin 5 of the integrated circuit IC, wherein the positive side of the third light-emitting diode LED3 in series is connected to pin 14 of the integrated circuit IC; pins 3 and 1 of the integrated circuit IC are connected through the thirteenth resistor R13; the positive pin of the third rectifier diode D3 is connected to the positive pin of the third capacitor C3, and the negative pin of the third rectifier diode D3 is connected to pin 1 of the integrated circuit IC.

[0069] Among them, the second switch SB2 is a self-reset switch. In order to prevent the self-reset switch from being accidentally pressed and causing rapid heating, the start time of the self-reset switch is set to 5 seconds. In order to ensure rapid heating, mite removal, etc., the cold start working time is set to 30 minutes.

Being set below the lever handle 26 will not greatly affect the operation, because the voltage in the same area is relatively stable, so it does not need to be adjusted frequently during use.

[0086] As a specific implementation method of installing the switch structure in the shell structure, the first step is to prepare a circuit board structure of the control circuit, and connect the power input line of the circuit board to the power plug 48 with a zero-fire mark; the second step is to connect the power output line of the circuit board to the wire connected to the heating wire of the electric blanket; the third step is to put the circuit board prepared in the above two steps into the bottom shell; the fourth step is to use screws to install the wire pressing block 46 in the power input wire pressing cavity 36 to make the power input line firm, and the wire pressing block 46 is installed in the power output wire pressing cavity 42 to make the power output line firm; the fifth step is to complete the installation of the first sliding switch K1 at the upper shell; the sixth step is to complete the installation of the adjusting rod 33 at the upper shell; the seventh step is to put the first switch handle cap 24 on the handle of the first switch SB1, and the second switch handle cap 25 on the second switch On the handle of SB2, in the eighth step, the upper shell with the first sliding switch K1 and the adjusting rod 33 installed is combined with the bottom shell with the circuit board installed.

In the tenth step, the decorative cover 52 is inserted into the screw hole 43 of the bottom shell, and the anti-touch cover 53 is inserted into the upper end of the hollow cylinder 8 where the adjusting rod is placed.

[0087] As a specific method of using the switch structure, the first step is to use a test pen to determine the live wire jack of the socket. The second step is to insert the power plug XP into the corresponding socket jack according to the neutral wire and live wire. The third step is to adjust the use according to the specific situation. When the temperature is low and the electric blanket needs to be used, the first sliding switch K1 or the second sliding switch K2 of the electric blanket is turned to the high position. During use, the cycle timer on time or the cycle timer off time is adjusted according to the temperature of the quilt to make the temperature in the quilt comfortable. If the weather temperature continues to drop to a low temperature, the cycle timer on time or the cycle timer off time is further adjusted to make the temperature in the quilt comfortable. This method is used to achieve a comfortable temperature in the quilt even in the coldest days. When the temperature rises, when the first sliding switch K1 or the second sliding switch K2 of the electric blanket is turned to the high position and the temperature in the quilt is felt to be high, the first sliding switch K1 or the second sliding switch K2 of the electric blanket is simply turned to the low position. When the first sliding switch K1 or the second sliding switch K2 of the electric blanket is in the low position and the temperature in the quilt is high again, it is time not to use the electric blanket. At this time, the anti-touch cover 53 can be covered. Next year, the first sliding switch K1 or the second sliding switch K2 of the electric blanket can be directly used to control the temperature of the electric blanket. Except for the voltage in the same area that changes greatly and requires adjustment of the cycle timing on time or the cycle timing off time, the cycle timing on time or the cycle timing off time is no longer adjusted during the later use. If adjustment is required, it is only a small adjustment, no longer as complicated as the previous adjustment. The comfortable temperature mentioned here refers to the highest temperature in the quilt that cannot cause waking up from heat, thirst, or sweating, and the lowest temperature in the quilt that cannot cause waking up from cold and the human body must not feel cold after getting up in the morning. In short, the best adjustment of the cycle timing on time and the cycle timing off time is to ensure that the human body is warm after getting up in the morning.

[0088] In this solution, the appearance, structure and operation method of the switch structure are similar to those of a traditional electric blanket switch, which is conducive to adapting to the usage and operation habits of people of all ages, especially the problem of inconvenience in operation caused by poor eyesight of the elderly.

[0089] Specifically, in the actual test process of the electric blanket, after the bed is heated, under the premise of ensuring the comfortable temperature of the bed, the comfortable temperature here refers to the bed being the hottest without waking people up from the heat or feeling overheated and uncomfortable, and the bed being the coldest without waking people up from the cold or feeling cold after getting up, the cycle timer is on for about 10 minutes, and the cycle timer is off for about 40 minutes. Calculated based on 10 hours, if the electric blanket is turned on all night, the human body will not be harmed by electricity for about 8 hours, that is, the damage caused by the electric blanket to the human body accounts for about 20%, which saves energy. From this perspective, about 80% of electricity can be saved. For each person, the length of time when the cycle timer is on is not much different, but the length of time when the cycle timer is off varies greatly. The main reason is that each person's body has different self-regulation abilities, the quality of bedding is different, the environment is different, the amount of clothes worn by the sleeper is different, etc.; with the maximum length of the cycle timer on being 30 minutes and the minimum length of the cycle timer off being 10 minutes, calculated based on 10 hours, if the electric blanket is turned on all night, the damage to the human body will be reduced by about 25%, and electricity will be saved by about 25%.

[0090] The above are preferred embodiments of the present invention. Those skilled in the art to which the present invention belongs can also change and modify the above embodiments. Therefore, the present invention is not limited to the above specific embodiments. Any obvious improvements, replacements or deformations made by those skilled in the art on the basis of the present invention fall within the scope of protection of the present invention.
