[0025] See also Figure 1-4 The utility model discloses a comfortable new type of piano key, comprising a base plate 1, a support frame 2 and a key body 3. The bottom surface of the support frame 2 is fixedly connected to the upper surface of the base plate 1, the inner wall of the key body 3 is rotatably connected to the outer surface of the support frame 2, the inner wall of the key body 3 is slidably connected with a black key 4, the upper surface of the key body 3 is fixedly connected with a heat-conducting cotton 5, the upper surface and the bottom surface of the key body 3 are provided with equidistantly arranged guide holes 9, the outer surface of the heat-conducting cotton 5 is in contact with the inner wall of the guide hole 9, a double-headed forward and reverse motor 18 is arranged inside the key body 3, the output end of the double-headed forward and reverse motor 18 is fixedly connected with two fan blades 16, and the inner wall of the key body 3 is fixedly connected with an electric heating tube 17.

[0026] A support block 6 is fixedly connected to the upper surface of the base plate 1, and a cushion block 7 is fixedly connected to the upper surface of the support block 6. By arranging the support block 6 and the cushion block 7, a certain supporting effect can be exerted on the key body 3 when it is pressed down, thereby avoiding excessive downward pressure.

[0027] The upper surface of the base plate 1 is threadedly connected with two threaded wires 12, and the bottom end of each threaded wire 12 passes through the base plate 1 and extends to the bottom of the base plate 1. By setting the threaded wire 12, the user can fix the device firmly under the action of the threaded wire 12 to avoid displacement during use.

[0028] Two limit posts 10 are fixedly connected to the bottom surface of the key body 3, and two limit cylinders 11 are fixedly connected to the upper surface of the base plate 1. The outer surface of each limit post 10 is slidably connected to the inner wall of the limit cylinder 11. By setting the limit posts 10 and the limit cylinders 11, the key body 3 can be limited to a certain extent under the action of the limit posts 10 and the limit cylinders 11 to avoid left and right movement.

[0029] Two first springs 8 are fixedly connected to the bottom surface of the black key 4, and the bottom end of each first spring 8 is fixedly connected to the inner bottom wall of the key body 3. By setting the first spring 8, the black key 4 can be assisted to bounce up after being pressed under the action of the first spring 8, thereby facilitating use by users.

[0030] The outer surface of the double-headed forward and reverse motor 18 is fixedly connected to a protective cover 14, and the outer surface of the protective cover 14 is fixedly connected to two limit rods 15, and the side surfaces of the two limit rods 15 that are away from each other are fixedly connected to the inner wall of the key body 3. By arranging the protective cover 14 and the limit rods 15, the double-headed forward and reverse motor 18 can be supported and fixed under the action of the protective cover 14 and the limit rods 15, so that it can be in a stable working state.

[0031] The upper surface of the base plate 1 is fixedly connected with a sleeve 13, the inner wall of the sleeve 13 is slidably connected with a support column 19, the upper surface of the support column 19 is fixedly connected to the bottom surface of the key body 3, and by arranging the sleeve 13 and the support column 19, the key body 3 can be assisted in pressing downward under the action of the sleeve 13 and the support column 19, and at the same time, a pushing platform is provided to improve the practical effect.

[0032] The bottom surface of the support column 19 is fixedly connected with a second spring 20, and the bottom end of the second spring 20 is fixedly connected to the inner bottom wall of the sleeve 13. By setting the second spring 20, the power required for popping up can be provided under the action of the second spring 20, so that it is convenient for people to use.

[0033] The working principle of the utility model is: first, the staff brings the device to a suitable position, then turns on the power of the double-headed forward and reverse motor 18 and the electric heating tube 17, so that it can be in a stable power-on state to avoid power outages during use. Then the staff firmly fixes the device through two threaded wires 12, and it can be used after being firmly fixed. The staff presses the key body 3 downward, and when the key body 3 moves downward, it will drive the limit column 10 and the support column 19 to retract downward. When the staff releases the key body 3, the key body 3 will rebound to reset under the action of the elastic force of the second spring 20. When the temperature on the surface of the key body 3 is too low When the double-headed forward and reverse motor 18 and the electric heating tube 17 are turned on, the user turns on the double-headed forward and reverse motor 18 and starts to rotate. The rotation of the double-headed forward and reverse motor 18 can drive the two fan blades 16 to rotate, thereby driving the air to be introduced from the guide hole 9. At the same time, the electric heating tube 17 starts to generate heat after being turned on. The introduced air contacts the electric heating tube 17 to complete the heat conversion and blows the heat wave to the thermal conductive cotton 5 for absorption, thereby increasing the temperature of the surface of the key body 3, effectively avoiding the discomfort of the user's body and fingers due to the low temperature of the key body 3, improving the comfort of the user during use, and enhancing the practical effect of the device.
