[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0022] Embodiment 1:

[0023] Reference Figure 1-Figure 4 The dust-proof test tube rack comprises: a hollow base 1, one side of the hollow base 1 is connected with an air inlet pipe 101, and a circle of slots 103 are arranged on the outer side of the upper surface of the hollow base 1; a transparent dust cover 2 is inserted into the slot 103 of the hollow base 1; a hollow column 3 is connected to the hollow base 1 vertically and equidistantly in a circle, and is connected with the internal cavity of the hollow base 1; an air jet 301 is arranged at the upper end of the hollow column 3.

[0024] The upper surface of the hollow base 1 is a conical inclined surface 104 , and a water collecting box 4 is placed at the center of the hollow base 1 .

[0025] When the cleaned test tube needs to be dried, the operator can remove the transparent dust cover 2 from the hollow base 1, and then the operator can turn the cleaned test tube upside down on the hollow column 3, and then the water attached to the inner wall of the test tube will flow down to the conical inclined surface 104 of the hollow base 1, and then the water flow will flow to the middle along the conical inclined surface 104, and then it will flow into the water collecting box 4 for collection. When the operator places the cleaned test tube on the hollow column 3, the hot air can be transported into the cavity of the hollow base 1 through the air inlet pipe 101 by an external hot air blower, and then the hollow base 1 will divert the hot air to each hollow column 3, and spray it into the test tube through the jet port 301. By controlling the external The hot air blower delivers hot air at a flow rate into the hollow base 1. When the hot air is sprayed into the test tube, the test tube will be suspended under the push of the gas, and thus will be separated from the hollow column 3, so as to more fully dry the inner wall of the test tube. When the gas enters the test tube, the gas in the test tube will flow downward along the test tube, and thus will be sprayed toward the conical inclined surface 104. Then, the water droplets attached to the conical inclined surface 104 will flow quickly into the water collecting box 4 under the blowing of the airflow, thereby preventing the water droplets attached to the conical inclined surface 104 from staying on the conical inclined surface 104 for a long time to breed bacteria, causing pollution to the test tubes that need to be cleaned or stored later, thereby effectively improving the protection effect of the test tubes.

[0026] In order to prevent dust floating in the outside air from adhering to the outer wall and the tube mouth of the test tube, when the test tube is turned upside down for cleaning or storage, a transparent dust cover 2 can be covered on the hollow base 1, so that the test tube can be fully dust-proofed, and when the test tube is dried, it is also convenient for the operator to observe the drying progress of the test tube through the transparent dust cover 2.

[0027] It should be noted that it is not necessarily possible to prevent dust from entering the test tube through the hot air. A filtering device can be set at the air inlet of the hot air blower, so that the hot air blown into the test tube can be purer, reducing the risk of dust contamination inside the test tube.

[0028] Embodiment 2:

[0029] Reference Figure 1-Figure 4 , the dust-proof test tube rack is basically the same as that of embodiment 1, and furthermore: a circle of arc chamfers 401 is provided at the opening of the water collecting box 4, and a circle of arc chamfers 401 is provided on the water collecting box 4, such as Figure 3 , Figure 4 As shown, when water dripping from the test tube flows along the conical inclined surface 104 into the water collecting box 4, the arc chamfer 401 can have a good guiding effect on the water flow, so that the water flow can flow into the water collecting box 4 more fully for collection, effectively improving the water collection effect.

[0030] A lifting rod 402 is fixedly connected to the water collecting box 4. Through the setting of the lifting rod 402, when the operator needs to take out the water collecting box 4 to clean the water stored therein, the operator can easily remove the water collecting box 4 from the hollow base 1 by holding the lifting rod 402, which provides convenience for the operator.

[0031] The transparent dust cover 2 is provided with a plurality of exhaust ports equidistantly arranged in a circle, and the exhaust ports of the transparent dust cover 2 are connected to an exhaust pipe 201, and the air outlet of the exhaust pipe 201 faces downward. By arranging the air outlet of the exhaust pipe 201 to face downward, when not in use, dust falling in the air can be prevented from entering the transparent dust cover 2 through the exhaust pipe 201, and then falling onto the hollow column 3, thereby contaminating the test tubes subsequently placed on the hollow column 3, thereby effectively improving the dust-proof effect on the test tubes.

[0032] A rubber layer is provided on the surface of the hollow column 3. By providing the rubber layer on the surface of the hollow column 3, when the test tube collides with the hollow column 3, or the jet port 301 of the hollow column 3 stops jetting, and the test tube falls, the risk of the test tube rupturing can be effectively avoided, thereby effectively improving the protection effect of the test tube.

[0033] Embodiment 3:

[0034] Reference Figure 1-Figure 4The dust-proof test tube rack is basically the same as that of Example 2, and further, the hollow column 3 is detachably connected to the hollow base 1 through a thread. By detachably connecting the hollow column 3 to the hollow base 1, when one of the hollow columns 3 is damaged, the operator can replace it separately, which effectively reduces the use cost of the test tube rack.

[0035] A plurality of anti-skid rubber feet 102 are equidistantly fixedly connected to the bottom of the hollow base 1. By setting the anti-skid rubber feet 102, when the test tube rack is placed on the table, the friction between the test tube rack and the table can be increased, thereby effectively ensuring the stability of the test tube rack.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
