The utility model discloses a chemical experiment test tube placing table, which relates to the technical field of experiment instruments, and comprises a table top, a test tube placing unit and a test tube cleaning unit, and the test tube placing unit comprises a water control tank, a rubber block, a support rod, a silica gel top block and a sponge ring. The test tube cleaning device is provided with the reliable test tube cleaning unit, test tubes after tests can be cleaned, waste water after cleaning can be collected, waste water containing chemical substances is prevented from emitting pungent smell, the reliable test tube placing unit is arranged, test tubes of different sizes and specifications can be effectively placed, and the test tube cleaning device is simple in structure, convenient to use and high in practicability. The test tubes are reversely inserted in the supporting rods after being cleaned, so that the test tubes are automatically subjected to water control and drying when placed, the silica gel top blocks and the rubber blocks support the tails and ports of the test tubes correspondingly, the sponge rings are inserted into the test tubes, the test tubes can be tightly supported and fixed, the openings of the test tubes are blocked, dust is prevented from entering the test tubes, and the service life of the test tubes is prolonged. And the cleanliness of the test tubes during taking is ensured.

The utility model relates to the technical field of constant-temperature incubators, in particular to a cleaning mechanism and a constant-temperature incubator, which comprise a cleaning mechanism, a telescopic component cleaning mechanism and a rotary nozzle cleaning mechanism fixedly connected with one end of the telescopic component cleaning mechanism, the water pump machine cleaning device has the advantages that the interior of the box body cleaning mechanism can be cleaned by controlling the water outlet amount of the water pump machine cleaning mechanism, and the larger the water outlet amount is, the faster the rotating speed of the rotating spray head cleaning mechanism is; the cleaning effect on dirt accumulated at the bottom of the box body cleaning mechanism can be obviously improved.
