Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a moisture-proof and heat-dissipating DVD player, including a main body 1, a disc 2, a display screen 3, control keys 4, support feet 5 and heat-dissipating slots 6. The disc 2 is arranged on the front of the main body 1, the display screen 3 is installed on one side of the disc 2, the control keys 4 are installed on one side of the display screen 3, the support feet 5 are fixedly connected to the bottom of the main body 1, the heat-dissipating slots 6 are opened on both sides of the main body 1, and an anti-slip pad is arranged at the bottom of the support feet 5 to ensure the firm fixation of the device through the anti-slip pad, facilitating use.

[0025] The main body 1 includes a housing 101, an electronic device 102, a cooling fan 103 and an opening and closing mechanism 104. The electronic device 102 is fixedly connected to the inside of the housing 101. The cooling fan 103 is installed at one end of the electronic device 102. The opening and closing mechanism 104 is arranged at both ends inside the housing 101. The opening and closing of the heat dissipation slot 6 is controlled by the opening and closing mechanism 104. In cooperation with the cooling fan 103, heat dissipation treatment or moisture-proof treatment can be carried out inside the main body 1. It is convenient to use, has a simple structure, can better extend the service life of the DVD player, reduce the work of manual inspection and maintenance. The number of the cooling fans 103 is two, which are arranged in the middle inside the main body 1 and face the position of the housing 101 for heat dissipation treatment of the main body 1. At the same time, after the opening and closing mechanism 104 closes the heat dissipation slot 6, heat is generated during the operation of the main body 1, and the heat dissipation slot 6 is closed to circulate the heat inside the main body 1 to achieve the effect of dehumidification.

[0026] The opening and closing mechanism 104 includes a lower mounting frame 110, a rotating lead screw 111, a transmission member 112, a driving motor 113, an opening and closing plate 114 and an upper mounting frame 115. The lower mounting frame 110 is fixedly connected to the inside of the housing 101. The rotating lead screw 111 is rotatably connected to the inside of the lower mounting frame 110. The transmission member 112 is arranged at one end of the lower mounting frame 110. The driving motor 113 is arranged at the other end of the transmission member 112. The opening and closing plate 114 is arranged on the top of the lower mounting frame 110. The upper mounting frame 115 is arranged on the top of the opening and closing plate 114. Under the action of the transmission member 112, the driving motor 113 drives the rotating lead screw 111 to rotate, and then moves the opening and closing plate 114 to open and close the heat dissipation slot 6. The size of the opening and closing plate 114 is larger than that of the heat dissipation slot 6 to ensure effective closing of the heat dissipation slot 6 and prevent humid air from entering the inside of the main body 1 when the device is not in use. The inside of the transmission member 112 is set as a rotating block. The number of the rotating blocks is two, which are respectively fixedly connected to one end of the rotating lead screw 111 and the output shaft of the driving motor 113. The transmission belt is sleeved outside the two rotating blocks, so that the transmission member 112 plays the role of power transmission.

[0027] The opening and closing plate 114 includes a plate body 120, a moving block 121 and a threaded hole 122. The moving blocks 121 are fixedly connected to the upper and lower ends of the opening and closing plate 114. The threaded holes 122 are opened inside the moving blocks 121. The threaded holes 122 are threadedly connected to the outside of the rotating lead screw 111. Therefore, the rotation of the rotating lead screw 111 drives the plate body 120 to move.

[0028] The inside of the upper mounting frame 115 is slidably connected to the moving block 121, so that the movement of the opening and closing plate 114 between the lower mounting frame 110 and the upper mounting frame 115 is stable.

[0029] When in use, place the device on the desktop and connect the player to play the DVD. During the playback process, the driving motor 113 drives the rotating lead screw 111 to rotate, so that the opening and closing plate 114 moves on the lower mounting frame 110 and moves away from the heat dissipation slot 6. With the cooperation of the heat dissipation fan 103, the operating device is cooled. When not in use, similarly, the opening and closing plate 114 closes the heat dissipation slot 6, thereby preventing humid air from entering the interior of the main body 1 and playing a moisture-proof role.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
