[0031] Further, the medicament putting assembly 202 further comprises a scale line 202e arranged on the surface of the vertical cylinder 202b, the vertical cylinder 202b is a transparent glass cylinder, the top of the vertical cylinder 202b is provided with a cover, the end of the push-pull rod 202d is fixedly installed with a stop rod, and the stop rod is connected to the end of the plastic cylinder 202a.

[0032] The scale line 202e is used for quantitative putting of the medicament, and the use performance of the medicament is ensured. In order to remove the scale on the wall of the cooling pipe 206, the anti-scale agent needs to be put. The cover is used for closing the top of the vertical cylinder 202b, so as to avoid dust and other impurities from falling into the inside of the vertical cylinder 202b and affecting the purity of the medicament. The stop rod is used for limiting the piston 202c, so as to ensure that the piston 202c is located at the bottom of the vertical cylinder 202b.

[0033] It should be noted that the anti-scale agent is added in the cooling water, the anti-scale agent can combine with calcium and magnesium ions in the water to form a compound which is not easy to deposit, so as to reduce the formation of scale.
