Description

Technical Field

[0001] The present invention relates to the technical field of potentiometric titration electrode brackets, in particular to a potentiometric titration electrode bracket and a storage box. Background Art

[0002] Potentiometric titration electrodes are key components in potentiometric titration analysis, and their performance directly impacts the accuracy of titration results. When not in use, the electrode must be properly stored in the titration electrode holder to maintain its sensitivity and extend its service life.

[0003] The above device does not have a closed temperature and humidity control storage box for storage and a structure for lifting and retrieving the titration electrode from the storage box when in use. As a result, the existing titration electrode and electrode sleeve are easily overturned when placed on the bracket due to the shape limitation of the bracket or when the table shakes. In addition, the open storage method cannot control the storage temperature and humidity of the titration electrode. When in use, the electrode sleeve of the titration electrode stores liquid inside, and a large amount of liquid is easily adhered to the outer wall of the sleeve during the electrode insertion process. Directly placing the titration electrode into the storage box is very likely to affect the humidity inside the box. Based on the shortcomings of the existing technology, the present invention designs a potentiometric titration electrode holder and storage box. Summary of the Invention

[0017] 1. A potentiometric titration electrode holder and storage box, when the humidity in the storage box main body is high and there are water droplets on the surface of the electrode sleeve, the temperature controller main body is started to control the temperature of the internal semiconductor chip to increase the temperature, and the temperature is guided to the temperature conducting fins by the temperature conducting tube to increase the temperature, and then the fan is started to filter the external air through the filter screen and enter the bottom cavity from the air inlet hole. The air entering the bottom cavity contacts the temperature conducting fins and is heated, and then passes through the ventilation groove into the storage box main body. At this time, the air in the storage box main body lifts the one-way rubber plate and is discharged from the exhaust hole. The hot air starts to flow continuously in the storage box main body and quickly heats and discharges the moisture in the storage box main body and the water droplets on the surface of the electrode sleeve. After the humidity in the storage box main body drops to a suitable range, the temperature controller main body turns off the fan and continues to work, so that the air directly enters the storage box main body without being heated by the temperature conducting fins, so that the temperature in the storage box main body drops to the same as the room temperature. The device is convenient for controlling the temperature and humidity in the storage box main body.

[0018] 2. This potentiometric titration electrode holder and storage box opens the top of the storage box body by rotating the sealing cover upward using a rotary joint, and then presses the control button to control the motor to drive the screw to rotate clockwise. The rotating screw pushes the lifting plate connected to the surface upward and drives the electrode holder body connected thereto and the internal titration electrode and electrode sleeve to move upward accordingly, so that the top of the titration electrode and electrode sleeve in the storage box body extends out of the storage box body to facilitate the experimenter to take or identify different titration electrodes and electrode sleeves. After the retrieval is completed, the control button is pressed to reverse the screw. The reversed screw drives the electrode holder body to move vertically downward under the limit of the limit plate and the limit slide rod to retract the electrode holder body, the titration electrode and the electrode sleeve into the storage box body. This device makes it easy to lift the electrode holder body for easy taking and placement. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Working principle: when a potentiometric titration electrode holder and storage box are used, in the initial state, the control button 102 and the thermometer and hygrometer 103 are first arranged on the front of the storage box body 1, and the rotary joint 201 arranged on the top of the storage box body 1 is rotatably connected to the sealing cover 2. A pressure plate 203 and a one-way rubber plate 204 are arranged in the exhaust hole 202 opened on the sealing cover 2, and the sealing cover 2 and the storage box body 1 are connected by an upper magnetic block 205 and a lower magnetic block 206. At the same time, the electrode holder body 104 is arranged inside the storage box body 1, so that the titration electrode and the electrode sleeve can be sealed and stored in the storage box body 1 for use, and a lower fixing plate 30 is arranged in the side cavity 301 opened on both sides of the inner cavity of the storage box body 1. 2. The upper fixed plate 303 and the limiting slide 304, the limiting plates 308 and the lifting plates 309 fixedly connected on both sides of the electrode holder body 104 are arranged on the limiting slide 304, the motor 306 and the screw rod 307 installed in the side cavity 301, so as to control the lifting and lowering of the electrode holder body 104 in the storage box body 1, and the bottom cavity 401 opened at the bottom of the storage box body 1 is respectively provided with a ventilation groove 402 and an air inlet 403 on the upper and lower sides, and a filter 405 is fixedly connected to the air inlet 403 below through a fixing bar 404, and a fan 406, a temperature conducting fin 407 and a temperature conducting pipe 408 are arranged above the air inlet 403, and the temperature conducting pipe 408 is connected to the temperature controller body 410, so as to control the temperature and humidity in the storage box body 1;

[0036] When the temperature and humidity in the storage box body 1 need to be controlled, first when the humidity in the storage box body 1 is high and there are water droplets on the surface of the electrode sleeve, the temperature control machine body 410 is started to control the internal semiconductor chip to heat up, and the temperature is transmitted to the temperature conducting fin 407 by the temperature conducting pipe 408 to heat it up. Then the fan 406 is started to filter the external air through the filter 405 and then enter the bottom cavity 401 through the air inlet 403. The air entering the bottom cavity 401 contacts the temperature conducting fin 407 and heats up, then passes through the ventilation groove 402 and enters the storage box body 1. At this time, the storage box The air in the main body 1 lifts the one-way rubber plate 204 and is discharged from the exhaust hole 202. The hot air starts to flow continuously in the storage box main body 1 to quickly dry out the moisture in the storage box main body 1 and the water droplets on the surface of the electrode sleeve. After the humidity in the storage box main body 1 drops to a suitable range, the temperature control machine main body 410 turns off the fan 406 and continues to work, so that the air enters the storage box main body 1 directly without being heated by the temperature conducting fins 407, so that the temperature in the storage box main body 1 drops to the same as the room temperature. This device is convenient for controlling the temperature and humidity in the storage box main body 1.

[0037] When it is necessary to lift the electrode holder body 104 for easy access, first use the rotary joint 201 to rotate the sealing cover 2 upward to open the top of the storage box body 1, and then press the control button 102 to control the motor 306 to drive the screw rod 307 to rotate clockwise. The rotating screw rod 307 pushes the lifting plate 309 connected to the surface to move upward and drives the electrode holder body 104 and the internal titration electrode and electrode sleeve connected thereto to move upward accordingly, so that the top of the titration electrode and electrode sleeve in the storage box body 1 extends out of the storage box body 1 to facilitate the experimenter to take or identify different titration electrodes and electrode sleeves. After the access is completed, press the control button 102 to reverse the screw rod 307. The reversed screw rod 307 drives the electrode holder body 104 to move vertically downward under the limit of the limit plate 308 and the limit slide 304, and the electrode holder body 104 and the titration electrode and electrode sleeve are retracted into the storage box body 1. This device makes it easy to lift the electrode holder body 104 for easy access.
