[0025] like Figure 1 and Figure 2As shown in , the multimedia air heater of the present invention includes a housing 1, in which a heating system and an air supply system are disposed. An air outlet 1-1 is disposed on the front of the housing 1, an air inlet 1-2 is disposed on the back of the housing 1, and a flip screen assembly is disposed on the top of the housing 1. The flip screen assembly includes a flip screen 4 and a video playback system electrically connected to the flip screen 4. A speaker 1-7 electrically connected to the flip screen 4 is also disposed in the housing 1, and the speaker 1-7 is located above the air inlet 1-2. A handle 8 is also provided on the housing 1, and the two ends of the handle 8 are respectively hinged to the two sides of the housing 1. The handle 8 can be rotated to the front side or the rear side of the housing 1. When the multimedia air heater of the present invention is packaged, the handle 8 does not add additional volume.

[0026] like Figure 4 As shown in the figure, a screen mounting groove 1-3 is provided on the top of the shell 1, a shaft mounting groove 1-5 is provided on an inner side of the screen mounting groove 1-3, shaft plug holes 1-6 are provided at both ends of the shaft mounting groove 1-5, and a screen starting groove 1-4 is provided on an inner side of the screen mounting groove 1-3. The screen starting groove 1-4 is not on the same side as the screen mounting groove 1-3, and the length of the screen starting groove 1-4 is less than the length of the corresponding inner side of the screen mounting groove 1-3.

[0027] like Figure 5 and Figure 6 As shown in , the flip screen assembly includes a flip screen housing 5 for fixing the flip screen 4. A shaft mounting portion 5-3 is provided on one side of the flip screen housing 5. The shaft mounting portion 5-3 is mounted in the shaft mounting groove 1-5. The two ends of the shaft mounting portion 5-3 are rotatably connected to the two ends of the shaft mounting groove 1-5. In this way, the flip screen assembly is rotatably connected to the housing 1, and the flip screen assembly can be as shown in FIG. Figure 1 As shown in FIG, it can be placed flat on the top of the housing 1, and can also be Figure 3 The flip stand shown in the figure is on the top of the shell 1. When the multimedia heater of the present invention is not in use, the flip screen assembly is placed flat on the top of the shell 1 and embedded in the screen mounting grooves 1-3. The flip screen assembly can be as flush with the edge of the top of the shell 1 as possible without adding extra volume. When the multimedia heater of the present invention is in use, the flip screen assembly can be rotated to stand on the top of the shell 1, which is convenient for watching screen entertainment and avoids the heater from directly conducting heat to the flip screen assembly through the top of the shell 1, thereby optimizing the working environment of the flip screen assembly and increasing the service life of the flip screen assembly. Moreover, when operating the flip screen assembly to rotate and stand on the top of the shell 1, the fingers can be inserted into the screen starting grooves 1-4 to move the flip screen assembly to rotate, which is easy to operate.

[0028] To prevent the flip screen assembly from moving axially, the shaft mounting portion 5-3 is loosely fitted into the shaft mounting slot 1-5. To facilitate assembly, the flip screen housing 5 comprises an upper housing shaft 5-1 and a lower housing 5-2, which are joined together. The flip screen 4 is clamped between the upper and lower housing shafts 5-1 and 5-2. The shaft mounting portion 5-3 is formed by joining the upper and lower housing shafts 5-1 and 5-2. A shaft protrusion 5-4 is provided at one end of the shaft mounting portion 5-3, and a detachable connecting shaft 7 is provided at the other end. The shaft protrusion 5-4 and the connecting shaft 7 are respectively inserted into corresponding shaft insertion holes 1-6.

[0029] When assembling the flip screen assembly on the top of the shell 1, first install the lower shell 5-2 so that the part of the lower shell 5-2 about the shaft protrusion 5-4 is inserted into the corresponding shaft plug-in hole 1-6, and the part of the lower shell about the shaft mounting portion 5-3 can be clearance-fitted in the rotating shaft mounting groove 1-5; then install the connecting shaft 7, which is located on the lower shell, and the other end of the shaft mounting portion 5-3 is inserted into the corresponding shaft plug-in hole 1-6, so that the lower shell is limited; finally, install the upper shell 5-1 so that the part of the upper shell about the shaft protrusion 5-4 is inserted into the corresponding shaft plug-in hole 1-6, and the upper shell and the lower shell are spliced up and down, so that the flip screen shell 5 as a whole is limited by the connecting shaft 7, and the shaft mounting portion 5-3 and the rotating shaft mounting groove 1-5 are clearance-fitted, and the overall structure is compact, which prevents the flip screen assembly from moving axially.

[0030] In addition, a circular shaft segment 7-2 is provided on the connecting shaft 7, and the circular shaft segment 7-2 is inserted into the shaft mounting portion 5-3. A limiting segment 7-1 is provided at one end of the circular shaft segment 7-2. The limiting segment 7-1 is inserted into the corresponding shaft plug-in hole 1-6 and is circumferentially limited by the shaft plug-in hole 1-6. The limiting segment 7-1 can be set as a rectangular parallelepiped, and a rectangular parallelepiped groove that is clearance-matched with the limiting segment 7-1 can be set in the shaft plug-in hole 1-6, thereby circumferentially limiting the connecting shaft 7. In this way, the connecting shaft 7 only rotates relative to the shaft mounting portion 5-3, and the connecting shaft 7 and the shaft plug-in hole 1-6 do not rotate relative to each other. It is only necessary to provide some damping structure between the shaft mounting portion 5-3 and the connecting shaft 7. For example, the contact surface between the shaft mounting portion 5-3 and the circular shaft segment 7-2 of the connecting shaft 7 can be set as a friction surface. The static friction force generated between the two can prevent the flip screen assembly from rotating uncontrollably during use.

[0031] The shaft mounting portion 5-3 is hollow, and the end surface of the shaft projection 5-4 is provided with a wire hole 5-5 that communicates with the hollow interior of the shaft mounting portion 5-3. The shaft insertion hole 1-6 connected to the shaft projection 5-4 communicates with the interior of the housing 1. The power cord of the flip screen 4 passes through the hollow interior of the shaft mounting portion 5-3, the wire hole 5-5, and the corresponding shaft insertion hole 1-6, into the interior of the housing 1, and is connected to the power supply of the heating and ventilation systems within the housing 1. This ensures that the power cord of the flip screen 4 is not pulled during rotation, ensuring stable power supply to the flip screen 4. Example 2

[0032] The multimedia heater of this embodiment is different from that of embodiment 1 in that spherical rotating shafts are provided at both ends of the shaft mounting portion 5-3, and correspondingly, the shaft plug-in holes 1-6 at both ends of the rotating shaft mounting groove 1-5 are both configured as spherical grooves that match the above-mentioned spherical rotating shafts. The shaft mounting portion 5-3 can also be rotatably connected to the rotating shaft mounting groove 1-5 and have a clearance fit, while the power cord of the flip screen 4 directly passes through the side of the shaft mounting portion 5-3 and the bottom of the rotating shaft mounting groove 1-5 to enter the interior of the shell 1, and is connected to the power supply of the heating system and the air supply system in the shell 1. In this way, when the flip screen assembly rotates, the power cord of the flip screen 4 can also be not involved.

[0033] The above are only specific embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced with equivalents without departing from the spirit and scope of the present invention, they should be included in the scope of protection of the claims of the present invention.
