However, this manual rinsing method can result in incomplete rinsing of the pH meter electrodes, resulting in contamination of the test reagent during use and affecting measurement accuracy. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution: an automatic flushing device for a pH meter electrode, comprising a device body 1, and a cleaning tank 101 provided inside the device body 1;

[0025] The device body 1 is internally connected to a sleeve 2 which is rotatably provided with a positioning mechanism. By inserting the pH meter electrode into the sleeve 2 and fixing the pH meter electrode with the positioning mechanism, the sleeve 2 is driven to rotate, thereby enabling the pH meter electrode to rotate inside the cleaning tank 101.

[0026] A cleaning ring 3 is slidably connected to the inside of the cleaning tank 101, and a plurality of spray heads 301 are equidistantly arranged circumferentially inside the cleaning ring 3. A plurality of flexible bristles 302 are equidistantly arranged circumferentially inside the cleaning ring 3, and a bellows 303 is fixedly connected to the inside of the cleaning ring 3. The cleaning ring 3 is raised and lowered inside the cleaning tank 101, thereby driving the spray head 301 to spray and clean the outer wall of the pH meter electrode, washing away the dirt and residue on the outer wall of the pH meter electrode. The bellows 303 can clean the stubborn stains remaining on the outer wall of the pH meter electrode, thereby improving the cleaning effect of the spray head 301.

[0027] A reciprocating screw rod 4 is rotatably connected inside the device body 1, and the side wall of the cleaning ring 3 is threadedly connected to the outer wall of the reciprocating screw rod 4 through a screw block. A vertical rod 401 is connected inside the cleaning tank 101, and the side wall of the cleaning ring 3 is slidably connected to the outer wall of the vertical rod 401. By driving the reciprocating screw rod 4 to rotate, the cleaning ring 3 can be raised and lowered on the outer wall of the reciprocating screw rod 4. While the cleaning ring 3 is being raised and lowered, it also slides on the outer wall of the vertical rod 401. Under the limiting action of the vertical rod 401, the cleaning ring 3 will not rotate during the lifting process.

[0028] A gear 2 405 is sleeved on the side wall of the sleeve 2, and a gear 1 404 is meshed with the side wall of the gear 2 405. The gear 1 404 is sleeved on the outer wall of the reciprocating screw 4. The rotation of the reciprocating screw 4 drives the gear 1 404 to rotate, and the gear 1 404 drives the gear 2 405 to rotate, so that the gear 2 405 can drive the sleeve 2 to rotate inside the device body 1. When the cleaning ring 3 is raised or lowered, the sleeve 2 rotates, thereby improving the cleaning efficiency of the pH meter electrode inside the cleaning tank 101.

[0029] The reciprocating screw 4 is sleeved with a conical tooth 2 403, and the side wall of the conical tooth 2 403 is meshed with a conical tooth 1 402. The outer wall of the device body 1 is connected to a motor, and the output end of the motor is sleeved with the conical tooth 1 402. The motor drives the conical tooth 1 402 to rotate, and then the conical tooth 1 402 drives the conical tooth 2 403 to rotate, thereby causing the conical tooth 2 403 to drive the reciprocating screw 4 to rotate.

[0030] A water storage tank is provided inside the device body 1, and a water pump is connected to the water storage tank. A fixed pipe is connected to the water pump port, and the other end of the fixed pipe is connected to the top of the bellows 303. When the pH meter electrode needs to be cleaned, the water pump is started to allow the fixed pipe to draw liquid from the water storage tank into the bellows 303, and the liquid enters the spray head 301 through the bellows 303 and sprays the pH meter electrode.

[0031] The positioning mechanism includes a reverse screw rod 201, a clamping block 202 and a sliding rod 203;

[0032] A reverse screw rod 201 is rotatably connected to the sleeve 2, and two clamping blocks 202 are threadedly connected to the outer wall of the reverse screw rod 201. A slide rod 203 is connected to the sleeve 2, and the other ends of the two clamping blocks 202 are slidably connected to the slide rod 203. After placing the pH meter electrode in the center position of the sleeve 2, the reverse screw rod 201 is rotated to make the two clamping blocks 202 move on the outer wall of the reverse screw rod 201 until the clamping blocks 202 clamp the pH meter electrode. While the clamping blocks 202 move, they also slide on the outer wall of the slide rod 203, thereby limiting the clamping blocks 202.

[0033] A V-shaped groove is provided inside each clamping block 202, and a pressure sensor 204 is provided inside each V-shaped groove. Through the setting of the V-shaped groove, the clamping block 202 can fit the outer wall of the pH meter electrode more closely, thereby improving the clamping effect of the pH meter electrode. The clamping pressure of the clamping block 202 on the pH meter electrode is fed back by the pressure sensor 204, thereby adjusting the clamping force of the clamping block 202 on the pH meter electrode to avoid hard damage to the outer wall of the pH meter electrode.

[0034] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
