[0030] Furthermore, sliding bars are symmetrically arranged on both sides of the dust shielding plate 4, and sliding grooves adapted to the sliding bars are opened on both sides of the inner wall of the installation slot body 2, and the dust shielding plate 4 slides up and down along the inner wall of the installation slot body 2 through the sliding bars and the corresponding sliding grooves.

[0031] Furthermore, a lower pull ring 8 is provided at the bottom of the dust shielding plate 4 , and a clamping groove 9 matched with the lower pull ring 8 is provided at the bottom of the inner wall of the installation slot body 2 .

[0032] Furthermore, the dust shielding plate 4 is made of a soft plastic plate, and the outer surface of the dust shielding plate 4 is provided with anti-slip grooves.

[0033] Furthermore, the position-limiting clamping mechanism 7 includes position-limiting clamping blocks 74 disposed on both sides of the inner wall of the air outlet 3 , and position-limiting baffles 10 adapted to the position-limiting clamping blocks 74 are disposed on both sides of the filter frame 5 .

[0034] Furthermore, the limit block 74 is arranged in the groove 71 opened on both sides of the inner wall of the air outlet 3, and the side of the groove 71 away from the filter frame 5 is provided with a spring placement groove 72, and the spring placement groove 72 is slidably connected with a movable slider 73 inside, one end of the movable slider 73 is fixedly connected to the corresponding limit block 74, and the other end is connected to the inner wall of the spring placement groove 72 through a reset spring 75.

[0035] Furthermore, a transmission connecting rod 77 is fixedly connected to the outer side of the movable slider 73, and slideways 76 adapted to the corresponding transmission connecting rod 77 are opened on both sides of the air outlet 3. The end of the transmission connecting rod 77 passing through the slideway 76 is fixedly connected to a limit releasing movable piece 78.

[0036] Embodiment 2: This embodiment provides a ventilation device structure, such as Figures 1 to 3 As shown, it includes a mounting groove body 2 opened on the vehicle body 1, an air outlet 3 is installed in the mounting groove body 2, a dust shielding plate 4 is slidably provided on the outer side of the air outlet 3, and the dust shielding plate 4 is made of a soft plastic plate material that can produce deformation. When the dust shielding plate 4 is pushed to move up and down, the dust shielding plate 4 can produce a relatively slight deformation.

[0037] Furthermore, a cavity adapted to the dust shielding plate 4 is provided inside the vehicle body 1 just above the air outlet 3, which can accommodate the dust shielding plate 4 and facilitate the storage of the dust shielding plate 4 into the vehicle body 1. Two symmetrical sliding bars are fixedly connected to the two sides of the dust shielding plate 4, and two symmetrical sliding grooves are provided on the inner wall of the mounting groove body 2. The two sliding bars are respectively slidably connected to the inside of the two sliding grooves. Through the setting of the sliding bars and the sliding grooves, the dust shielding plate 4 can be guided and limited, thereby enhancing the stability of the dust shielding plate 4 when moving up and down.

[0038] Furthermore, the outer surface of the dust shielding plate 4 is provided with anti-slip grooves, which makes it convenient for people to manually move the dust shielding plate 4 up and down, and the friction between the dust shielding plate 4 and the cavity opened inside the vehicle body 1 is relatively large. When the dust shielding plate 4 is pushed into the interior of the cavity, the dust shielding plate 4 will not slide down out of the interior of the cavity by itself. It is necessary to manually pull down the lower pull ring 8 to pull the dust shielding plate 4 out of the interior of the cavity.

[0039] like Figure 4 As shown, a lower pull-down ring 8 is fixedly connected to the bottom surface of the dust shielding plate 4, and a slot 9 matched with the lower pull-down ring 8 is provided on the bottom inner wall of the mounting groove body 2. When the dust shielding plate 4 slides out of the cavity, the lower pull-down ring 8 can be inserted into the slot 9. The lower pull-down ring 8 can facilitate the pulling down of the dust shielding plate 4 and also play a limiting role when the dust shielding plate 4 is closed.

[0040] Furthermore, a filter frame 5 is provided inside the air outlet 3, and a large particle filter plate 6 is installed in the middle of the filter frame 5. The large particle filter plate 6 can prevent larger particles or garbage from entering the air outlet 3 when using the air conditioner.

[0041] like Figures 5-6As shown, two symmetrical limit clamping mechanisms 7 are provided between the filter frame 5 and the air outlet 3, and the limit clamping mechanism 7 includes a limit clamping block 74. The two sides of the filter frame 5 are fixedly connected with the limit baffle 10, and the limit clamping block 74 is adapted to the limit baffle 10. The limit clamping block 74 can limit the limit baffle 10, thereby facilitating the installation of the filter frame 5 inside the installation slot 2. The limit clamping mechanism 7 also includes an adaptation groove 71 opened on the inner wall of the air outlet 3, and the inner wall of the adaptation groove 71 is provided with a spring placement groove 72. The setting of the spring placement groove 72 facilitates the sliding block 73 to slide inside the spring placement groove 72.

[0042] The spring placement groove 72 is internally slidably connected with a movable slider 73, one end of which is fixedly connected to a limit block 74. When the movable slider 73 slides, it can drive the limit block 74 to move. The end of the movable slider 73 away from the limit block 74 is fixedly connected with a reset spring 75 arranged at an equal distance. The setting of the reset spring 75 facilitates the reset of the limit block 74.

[0043] The end of each return spring 75 away from the movable slider 73 is fixedly connected to the inner wall of the spring placement groove 72. The number of return springs 75 can be any number. In this embodiment, there are three. The outer surface of the air outlet 3 is also provided with a slideway 76. The outer surface of the movable slider 73 is fixedly connected with a transmission connecting rod 77. The transmission connecting rod 77 is slidably connected to the inside of the slideway 76. The transmission connecting rod 77 can slide inside the slideway 76. The end of the transmission connecting rod 77 away from the movable slider 73 is fixedly connected with a limit release movable plate 78. Since the transmission connecting rod 77 is fixed to the movable slider 73, when the transmission connecting rod 77 moves, it can drive the movable slider 73 to move, and then drive the limit block 74 to move.

[0044] Working principle: when the ventilation device is not needed, the lower pull ring 8 is pulled downward, and the lower pull ring 8 moves downward to drive the dust shielding plate 4 to move downward, so as to shield the air outlet 3, and the lower pull ring 8 is inserted into the inside of the card slot 9, so as to limit the dust shielding plate 4 and enhance the stability of the dust shielding plate 4 when shielding; when the ventilation device is needed, the dust shielding plate 4 is pushed upward, and since the outer surface of the dust shielding plate 4 is provided with anti-slip grooves, it is convenient to manually push the dust shielding plate 4 upward into the cavity opened inside the vehicle body 1, so as to expose the air outlet 3;

[0045] Furthermore, all parts of the present application that are not described in detail are the same as the prior art or are implemented using the prior art.

[0048] 2. The utility model sets a limit card connection mechanism. When the filter frame and the large particle filter screen need to be removed for cleaning, first slide the limit moving piece to both ends to release the limit moving piece. When the limit moving piece slides, it can drive the transmission connecting rod to slide. When the transmission connecting rod slides, it can drive the moving slider to move inside the spring placement groove, so that the limit card block can slide into the spring placement groove, so that the filter frame and the large particle filter screen can be easily taken out for cleaning.

[0049] 3. The utility model provides a pull-down ring and a card slot. When the dust shielding plate is pulled downward, the pull-down ring can be inserted into the card slot, thereby enhancing the stability of the dust shielding plate.
