[0026] Figure 4 for Figure 1 A front view of a ventilation mechanism in a snap-on louver for a laboratory fan vent is shown. A snap-on louver for a laboratory fan vent comprises a ventilation pipe 1, a limiting groove 2 is provided on the front of the inner wall of the ventilation pipe 1, a slot 3 is provided on the front of the inner wall of the limiting groove 2, a clamping sleeve 4 is movably sleeved inside the ventilation pipe 1, a sealing sleeve 5 is fixedly sleeved outside the clamping sleeve 4, an elastic plate 6 is fixedly connected to the side of the clamping sleeve 4, a clamping block 7 is fixedly connected to the outside of the elastic plate 6, a stretching column 8 is fixedly connected to the side of the clamping sleeve 4, a first limiting ring 9 is fixedly sleeved inside the clamping sleeve 4, a first louver blade 10 is movably sleeved inside the first limiting ring 9, a second limiting ring 11 is fixedly sleeved inside the first limiting ring 9, a second louver blade 12 is movably sleeved inside the second limiting ring 11, a filter cover 13 is movably sleeved outside the second limiting ring 11, a sliding ball 14 is movably sleeved on the front of the inner wall of the limiting groove 2, and a ventilation mechanism 15 is arranged inside the ventilation pipe 1.

[0027] The elastic plate 6 is made of stainless steel, and the elastic plate 6 is adapted to the limiting groove 2; by setting the elastic plate 6, when the shutter is assembled, the sleeve 4 is sleeved on the inside of the ventilation pipe 1, and the sleeve 4 can drive the elastic plate 6 to be sleeved on the inside of the limiting groove 2, that is, drive the clamping block 7 to be sleeved on the inside of the clamping groove 3, so that the clamping block 7 can limit and fix the sleeve 4 on the inside of the ventilation pipe 1 through the elastic plate 6, thereby achieving the assembly effect of the shutter, so that when the shutter is disassembled, the shutter is stretched, and the elastic plate 6 is contracted, and the sleeve 4 is removed from the inside of the ventilation pipe 1, thereby bringing convenience to the disassembly and assembly of the shutter, that is, improving the practical effect of the shutter.

[0028] The sealing sleeve 5 is compatible with the ventilation pipe 1, and the material of the sealing sleeve 5 is rubber material; by setting the sealing sleeve 5, when the shutter is assembled, the sealing sleeve 5 can fill the gap between the clamping sleeve 4 and the ventilation pipe 1, so as to avoid the problem that the sealing sleeve 5 is easy to shake when a large gap is generated between the sealing sleeve 5 and the ventilation pipe 1, thereby improving the sealing inside the ventilation pipe 1.

[0029] There are two stretching columns 8, and the two stretching columns 8 are symmetrically distributed with the clamping sleeve 4 as the symmetry axis; by setting the stretching columns 8, when the blinds need to be disassembled, the stretching columns 8 are pulled, so that the stretching columns 8 can drive the clamping sleeve 4 to move horizontally, that is, drive the clamping sleeve 4 to move out from the inside of the ventilation pipe 1, thereby avoiding the problem that the clamping sleeve 4 is too tightly fitted and makes it difficult to disassemble the clamping sleeve 4.

[0030] There are five No. 1 louvers 10, and the five No. 1 louvers 10 are parallel to each other; by setting the No. 1 louvers 10, when adjusting the wind direction of the blinds, the No. 1 louvers 10 are turned so that multiple No. 1 louvers 10 can rotate back and forth, so that the multiple No. 1 louvers 10 can guide the airflow in the reciprocating direction, thereby achieving the effect of adjusting the reciprocating direction of the airflow.

[0031] The No. 2 limiting ring 11 is compatible with the No. 1 limiting ring 9, and the No. 2 limiting ring 11 and the clamping sleeve 4 are parallel to each other; by setting the No. 2 limiting ring 11, when adjusting the wind direction of the blinds, the No. 2 louver 12 is moved so that the No. 2 louver 12 can be flipped up and down, thereby achieving the effect of guiding the airflow in the up and down directions.

[0032] The filter cover 13 is movably sleeved inside the No. 1 limiting ring 9, and the material of the filter cover 13 is a synthetic fiber material; by setting the filter cover 13, when air flow is being transported, the filter cover 13 can filter the air flow entering the ventilation pipe 1, thereby preventing dust accompanying the air flow from entering the ventilation pipe 1 and causing the ventilation pipe 1 to become dirty.

[0033] There are several sliding balls 14, which are evenly distributed on the front side of the inner wall of the limiting groove 2. By setting the sliding balls 14, when the ferrule 4 is assembled and disassembled for a long time, the sliding balls 14 can block the block 7, thereby avoiding the problem of serious wear of the block 7 caused by friction with the inner wall of the limiting groove 2 when the block 7 slides, thereby improving the smoothness of the movement of the ferrule 4.

[0034] The ventilation mechanism 15 includes a rotating motor 151, which is fixedly installed inside the ventilation pipe 1, and a fan blade 152 is fixedly sleeved on the output shaft of the rotating motor 151; by setting the ventilation mechanism 15, when the ventilation pipe 1 is ventilated, the rotating motor 151 is started, so that the rotating motor 151 can drive the fan blade 152 to rotate rapidly inside the ventilation pipe 1, so that the airflow inside the ventilation pipe 1 can flow rapidly, thereby achieving the airflow conveying effect.

[0035] The working principle of the snap-on shutter for the vent of the laboratory fan provided by the utility model is as follows:

[0036] Step 1: First, when assembling the shutter, the sleeve 4 is sleeved on the inside of the ventilation pipe 1. At this time, the sleeve 4 can drive the elastic plate 6 to be sleeved on the inside of the limiting groove 2, that is, drive the clamping block 7 to be sleeved on the inside of the clamping groove 3, so that the clamping block 7 can limit and fix the sleeve 4 in the inside of the ventilation pipe 1 through the elastic plate 6, thereby achieving the assembly effect of the shutter. When the shutter is disassembled, the shutter is stretched and the elastic plate 6 is contracted. At this time, the sleeve 4 can be removed from the inside of the ventilation pipe 1, which facilitates the disassembly and assembly of the shutter, that is, improves the practical effect of the shutter. When assembling the shutter, the sealing sleeve 5 can fill the gap between the sleeve 4 and the ventilation pipe 1. , so as to avoid the problem that the sealing sleeve 5 is easy to shake when a large gap is generated between the sealing sleeve 5 and the ventilation pipe 1, thereby improving the sealing inside the ventilation pipe 1. When the shutter needs to be disassembled, the stretching column 8 is pulled, so that the stretching column 8 can drive the clamping sleeve 4 to move horizontally, that is, drive the clamping sleeve 4 to move out from the ventilation pipe 1, thereby avoiding the problem that the clamping sleeve 4 is more difficult to disassemble due to the tight fit of the clamping sleeve 4. When adjusting the wind direction of the shutter, the No. 1 louver 10 is dialed, so that the multiple No. 1 louver blades 10 can reciprocate, so that the multiple No. 1 louver blades 10 can guide the airflow in the reciprocating direction, thereby achieving the effect of adjusting the reciprocating direction of the airflow;

[0037] Step 2: When adjusting the wind direction of the blinds, move the No. 2 blind 12 so that the No. 2 blind 12 can be flipped up and down, thereby achieving the effect of guiding the airflow in the up and down directions. When conveying the airflow, the filter cover 13 can filter the airflow entering the ventilation pipe 1, thereby preventing dust accompanying the airflow from entering the ventilation pipe 1, causing the ventilation pipe 1 to become dirty. When the ferrule 4 is assembled and disassembled for a long time, the sliding ball 14 can block the block 7, thereby preventing the block 7 from rubbing against the inner wall of the limit groove 2 when sliding, causing serious wear of the block 7, thereby improving the smoothness of the movement of the ferrule 4. When ventilating the ventilation pipe 1, start the rotating motor 151, so that the rotating motor 151 can drive the fan blades 152 to rotate rapidly inside the ventilation pipe 1, so that the airflow inside the ventilation pipe 1 can flow rapidly, thereby achieving the airflow conveying effect.

[0038] Compared with the related art, the buckle-type shutter for the vent of the laboratory fan provided by the utility model has the following beneficial effects:

[0039] By providing the elastic plate 6, when assembling the shutter, the sleeve 4 is sleeved on the inside of the ventilation pipe 1, and the sleeve 4 can drive the elastic plate 6 to be sleeved on the inside of the limiting groove 2, that is, drive the clamping block 7 to be sleeved on the inside of the clamping groove 3, so that the clamping block 7 can limit and fix the sleeve 4 on the inside of the ventilation pipe 1 through the elastic plate 6, thereby achieving the assembly effect of the shutter, so that when the shutter is disassembled, the shutter is stretched, the elastic plate 6 is contracted, and the sleeve 4 is removed from the inside of the ventilation pipe 1, thereby bringing convenience to the disassembly and assembly of the shutter, that is, improving the practical effect of the shutter.
