With the development of economic globalization and the deepening of world cultural exchanges, the fireplace has changed from a simple heating tool to a culture. At present, there is a fireplace on the market that uses electricity as energy. This fireplace has no open flame, but uses some other means to simulate the effect of the burning flame in the fireplace. Some simulated light is set on the front of the fireplace and reflected onto the flat imaging screen to form a simulated flame, thereby achieving a mimicry effect.

[0003] For example, the public document with application number 202123330906.4 discloses a three-dimensional flame electric fireplace with a humidification function. The utility model introduces atomized pure water into the interior of the exhaust hole through a conduit to humidify the hot air, thereby realizing the air humidification function of the device, keeping the environment inside the room moist, facilitating people's daily activities, and improving the functionality of the device. However, regardless of whether the electric fireplace is used or not, its display module is always exposed to the outside. Long-term exposure will cause a large amount of dust to adhere to the surface of the display module, and it may also be scratched by foreign objects, affecting the viewing experience of subsequent use.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 3 As shown, an electric fireplace with a multi-color gradual extinguishing function includes a fireplace body 1, a carved base 2 is fixedly installed on the bottom end of the outer surface of the fireplace body 1, a display screen 3 is fixedly installed on the inner surface of the fireplace body 1, a magnetic suction sheet 4 is fixedly installed below the inner surface of the fireplace body 1 and in front of the display screen 3, and a protective mechanism 5 is arranged above the inner surface of the fireplace body 1.

[0023] By adopting the above technical solution, the display screen 3 can be used to display the simulated flame;

[0024] Furthermore, the protection mechanism 5 includes a winding rod 501 rotatably mounted above the inner surface of the fireplace body 1 , and a driving motor 502 is disposed at the right end of the winding rod 501 , and the driving motor 502 is disposed in the inner wall of the fireplace body 1 .

[0025] By adopting the above technical solution, the driving motor 502 controls the rotation direction of the winding rod 501 by rotating forward and reverse.

[0026] Furthermore, the protection mechanism 5 also includes a curtain 503 arranged around the surface of the rolling rod 501 , and the surface shape and color of the curtain 503 match the fireplace body 1 .

[0027] By adopting the above technical solution, the forward-rotating reeling rod 501 can lower the curtain 503 to protect the display screen 3, and the reverse-rotating reeling rod 501 can retract the curtain 503 and open the display screen 3 for use.

[0028] Furthermore, the protection mechanism 5 also includes a weight plate 504 fixedly installed at the bottom end of the curtain 503 . The weight plate 504 is made of metal and can be exactly correspondingly adsorbed with the magnetic attraction plate 4 .

[0029] By adopting the above technical solution, the counterweight plate 504 can use its own gravity to pull the curtain 503 downward, and can also be adsorbed and fitted with the magnetic sheet 4, so as to fix the unfolded curtain 503 and prevent the curtain 503 from floating.

[0030] like Figure 4-Figure 5 As shown, a circuit component 6 is fixedly arranged on the rear side of the display screen 3 , and a power plug 7 is fixedly installed below the rear end of the circuit component 6 .

[0031] By adopting the above technical solution, after the power plug 7 is inserted into the power socket, it can supply power to the circuit component 6.

[0032] Furthermore, the circuit component 6 is composed of a switch S1, a first resistor R1, a second resistor R2, a third resistor R3, a capacitor C1, a transistor Q1, a light-emitting diode L1 and a voltage follower U1, and the switch S1, the first resistor R1, the second resistor R2, the third resistor R3, the capacitor C1, the transistor Q1, the light-emitting diode L1, the voltage follower U1 and the power plug 7 are connected and assembled using a specific circuit to form a complete current path.

[0033] By adopting the above technical solution, after the switch S1 is disconnected, the capacitor C1 is slowly discharged through the first resistor R1 and the third resistor R3, the voltage across the capacitor C1 is slowly reduced, and the output voltage of the operational amplifier also decreases along with the voltage of the capacitor C1, so that the transistor Q1 slowly exits the saturation state, and the brightness of the light-emitting diode L1 gradually decreases until the transistor Q1 is cut off and extinguished, making the dynamic extinguishing display of the entire flame softer and more natural, and extremely consistent with the actual flame extinguishing state.

[0034] Working principle: when using the electric fireplace with multi-color gradual extinguishing function, first, when using the fireplace body 1 to display the flame, the driving motor 502 drives the reeling rod 501 to rotate, reels the curtain 503, and exposes the display screen 3, then inserts the power plug 7 into the socket to power on, turns on the fireplace body 1 to close the switch S1, and the capacitor C1 is quickly fully charged. In the circuit, the voltage follower U1 output pin 6 follows the change of the voltage across the capacitor C1, so the switch S1 is closed, and the pin 6 outputs the required voltage to make the transistor Q1 saturated and turned on, and the light-emitting diode L1 is lit. The entire fireplace body 1 uses the display screen 3 to cooperate with multiple constantly changing light-emitting diodes L1 to perform flame imaging. After use, the switch S1 is disconnected and the fireplace body is closed. 1, the capacitor C1 is slowly discharged through the first resistor R1 and the third resistor R3, the voltage across the capacitor C1 is slowly reduced, and the output voltage of the operational amplifier also decreases with the voltage of the capacitor C1, so that the transistor Q1 slowly exits the saturation state, and the brightness of the light-emitting diode L1 gradually decreases until the transistor Q1 is turned off, and then, the driving motor 502 is turned on in the reverse direction to reverse the winding rod 501. At this time, the curtain 503 gradually has redundant parts, and under the gravity of the counterweight plate 504, it moves downward and extends, gradually covering the display screen 3, and the counterweight plate 504 is adsorbed by the magnetic suction plate 4, so that the entire curtain 503 is stably fixed on the front side of the display screen 3, and the display screen 3 is effectively protected and covered. This is the working principle of the electric fireplace with a multi-color gradual extinguishing function.
