[0022] The utility model provides a small adsorber for a biosafety countertop, which comprises a casing 101, a blower 105, two storage batteries 106, a mounting plate 107, a plurality of clamping blocks 108, a screen 109, a plurality of anti-slip pads 110, two sets of pulling assemblies, a placing assembly, multiple sets of air inlet assemblies and a control assembly. The blower 105 is arranged inside the casing 101. The mounting plate 107 is arranged on the upper surface of the casing 101. One ends of the plurality of clamping blocks 108 are respectively fixedly connected with the mounting plate 107, and the other ends of the plurality of clamping blocks 108 respectively penetrate through the casing 101 and are clamped with the casing 101. The screen 109 is fixedly connected to the middle of the mounting plate 107. The placing assembly is arranged on the lower surface of the mounting plate 107. The two storage batteries 106 are both arranged inside the casing 101. A charging port 102 is arranged on the outer side of the casing 101.

The multiple sets of air inlet assemblies are all clamped with the casing 101. The two sets of pulling assemblies are symmetrically arranged on the upper surface of the mounting plate 107. The control assembly is arranged on the outer side of the casing 101.

[0023] In this embodiment, the casing 101 is placed on the countertop inside the biosafety cabinet, and then the blower 105 is started. The rotation of the blower 105 causes a negative pressure to be generated inside the casing 101, so that harmful gases and particles on the countertop follow the air and enter the inside of the casing 101 through the multiple sets of air inlet assemblies. Then, the harmful gases and particles in the air are adsorbed and purified by the activated carbon in the placing assembly. The treated air is discharged from the casing 101 through the screen 109. The two storage batteries 106 are charged through the charging port 102, and the blower 105 is powered by the two storage batteries 106. When it is necessary to replace the activated carbon in the placing assembly, the two sets of pulling assemblies are pulled upward. The two sets of pulling assemblies respectively drive the mounting plate 107 to move upward. The mounting plate 107 drives the plurality of clamping blocks 108 to separate from the casing 101, so as to take out the placing assembly. Then, the placing assembly is separated from the mounting plate 107, and then the activated carbon in the placing assembly can be replaced.

[0024] Further, the placing assembly includes a placing cylinder 111 and a threaded ring 112. The threaded ring 112 is fixedly connected with the mounting plate 107 and is located on the lower surface of the mounting plate 107. The placing cylinder 111 is sleeved on the outer side of the threaded ring 112 and is threadedly connected with the threaded ring 112.

[0025] In this embodiment, activated carbon is placed inside the placement cylinder 111, and then the placement cylinder 111 is threadedly connected to the threaded ring 112, thereby fixing the placement cylinder 111 to the mounting plate 107.

[0026] Furthermore, each intake component includes a mounting frame 113, a clamping frame 114, and a filter net 115. The mounting frame 113 is attached to the outer side of the housing 101. One end of the clamping frame 114 is fixedly connected to the mounting frame 113, and the other end of the clamping frame 114 penetrates through the housing 101 and is clamped to the housing 101. The filter net 115 is fixedly connected to the mounting frame 113 and is located inside the mounting frame 113.

[0027] In this embodiment, the mounting frame 113 is fixed by clamping the clamping frame 114 to the housing 101. The filter net 115 is installed by the mounting frame 113, and larger debris is filtered by the filter net 115.

[0028] Furthermore, the control component includes a display screen 116, a switch button 117, and a wind speed button 118. The display screen 116 is fixedly connected to the housing 101 and is located on the outer side of the housing 101. Both the switch button 117 and the wind speed button 118 are arranged on the outer side of the display screen 116.

[0029] In this embodiment, the blower 105 is stopped or started by the switch button 117, and the rotation speed of the blower 105 is controlled by the wind speed button 118.

[0030] Furthermore, each pulling component includes two vertical plates 119 and a grip rod 120. Both of the two vertical plates 119 are fixedly connected to the mounting plate 107 and are respectively located on the upper surface of the mounting plate 107. Both ends of the grip rod 120 are fixedly connected to the two vertical plates 119.

[0031] In this embodiment, when the grip rod 120 is pulled, the grip rod 120 drives the mounting plate 107 to move upward through the two vertical plates 119.

[0032] Furthermore, each pulling component further includes an anti-slip sleeve 121, and the anti-slip sleeve 121 is sleeved on the outer side of the grip rod 120.

[0033] In this embodiment, the friction of the grip rod 120 can be enhanced by the anti-slip sleeve 121.

[0034] Furthermore, the housing 101 has a through hole 103 adapted to the mounting plate 107 and a plurality of card slots 104 adapted to the clamping blocks 108.

[0035] In this embodiment, the through hole 103 is used to place the mounting plate 107. The mounting plate 107 is fixed to the casing 101 by inserting a plurality of the clamping blocks 108 into the corresponding clamping grooves 104 respectively.

[0036] Advantages of the present utility model: Place the casing 101 on the tabletop inside the biological safety cabinet, and then start the fan 105. The rotation of the fan 105 causes a negative pressure to be generated inside the casing 101, so that harmful gases and particles on the tabletop follow the air and enter the inside of the casing 101 through the filter net 115. Then, the activated carbon in the placement cylinder 111 adsorbs and purifies the harmful gases and particles in the air. The treated air is discharged to the casing 101 through the leakage net 109. Charge the two storage batteries 106 through the charging port 102, and supply power to the fan 105 through the two storage batteries 106. When it is necessary to replace the activated carbon in the placement cylinder 111, pull up the two grip rods 120. The two grip rods 120 drive the mounting plate 107 to move upward respectively. The mounting plate 107 drives a plurality of the clamping blocks 108 to separate from the casing 101, so as to take out the placement cylinder 111. Then rotate the placement cylinder 111 to separate the placement cylinder 111 from the threaded ring 112, and then replace the activated carbon in the placement cylinder 111. This method can effectively solve the problems that the adsorber has a complex structure and a large volume and cannot be placed inside the biological safety cabinet, thus making it difficult to adsorb and purify the leakage of harmful gases and particles on the tabletop of the biological safety cabinet.
