[0024] Specifically, through weighing assembly 2 drives container assembly 3 to elevate, the bottom of filling pipe 5 contacts sealing plate 36 and applies downward extrusion force, the pressure overcomes the thrust of spring 37, forces sealing plate 36 to slide downward, until leak groove 52 on filling pipe 5 completely enters the inner chamber of cylinder 32, raw materials are introduced through filling pipe 5, metering valve 51 accurately controls the filling flow of raw materials, raw materials flow into the inner chamber of cylinder 32 through leak groove 52, and then flow into liquid storage tank 31 through leak hole 33, during the adding process, since guide pipe 34 is sleeved outside filling pipe 5, a relatively sealed passage is formed, so that the inside of cylinder 32 and liquid storage tank 31 is greatly blocked from contacting with the air outside, in this way, the whole process of raw materials from filling pipe 5 into liquid storage tank 31 is carried out in a relatively closed environment, thereby avoiding the contact of raw materials with air, effectively reducing the weight loss caused by the volatility of part of raw materials, ensuring the accuracy of weighing, and further ensuring the precision of disinfectant solution preparation ratio.

[0025] In the embodiment, the side surface of L type mount 4 is installed with fixed plate 6, and the side of fixed plate 6 is installed with limiting frame 61 for limiting liquid storage tank 31.

[0026] Specifically, when placing liquid storage tank 31 on weighing platform 23, limiting frame 61 abuts against liquid storage tank 31, so that the position is fixed, and the coaxiality of guide pipe 34 and filling pipe 5 is ensured, which enables filling pipe 5 to be smoothly inserted into guide pipe 34, avoids the deviation of position, ensures that filling pipe 5 can be accurately inserted, and avoids the collision and damage of guide pipe 34, filling pipe 5 and other components during the insertion process, and ensures that the filling operation can be accurately carried out according to the preset process.

[0027] In the embodiment, the weighing assembly 2 comprises an electric push rod 21 installed on the top surface of the operation table 1, the telescopic end of the electric push rod 21 slidingly penetrates through the bottom surface of the operation table 1 and extends upward, the telescopic end of the electric push rod 21 is fixedly installed with a lifting plate 22, and the top surface of the lifting plate 22 is installed with a weighing platform 23 for placing a liquid storage tank 31.

[0028] Specifically, the electric push rod 21 drives the lifting plate 22 to lift, and then drives the weighing platform 23 installed on the top surface of the lifting plate 22 and placing the liquid storage tank 31 to lift, so as to realize the docking and separation of the liquid storage tank 31 and the filling pipe 5.

[0029] In the embodiment, the top of the liquid storage tank 31 is fixedly communicated with a discharge pipe 38 near the edge, and the discharge pipe 38 is screwed with a tank cover 39.

[0030] Specifically, by opening the tank cover 39 and overturning the liquid storage tank 31, the weighed disinfectant can flow out of the discharge pipe 38.

[0031] Meanwhile, the contents not described in detail in the specification all belong to the prior art known by those skilled in the art.

[0032] Working principle: when in use, first, place the container assembly 3 on the weighing platform 23 stably, adjust the position to make the liquid storage tank 31 tightly abut against the limiting frame 61, at this time, the guide pipe 34 and the filling pipe 5 are accurately in the same vertical line.

[0033] Then, start the electric push rod 21, the telescopic end of which pushes the lifting plate 22 and the weighing platform 23 to move upward, drives the whole container assembly 3 to rise, and the guide pipe 34 gradually sleeves into the bottom end of the filling pipe 5, as the container assembly 3 continues to rise, the bottom end of the filling pipe 5 contacts the sealing plate 36 and applies a downward extrusion force, the pressure overcomes the pushing force of the spring 37, forces the sealing plate 36 to slide downward, until the leakage groove 52 on the filling pipe 5 completely enters the inner cavity of the cylinder 32.

[0034] At this time, the symmetrical platform 23 is peeled to eliminate the influence of the container assembly 3 on the subsequent weighing, and after the peeling is completed, the filling process is started, the raw material is introduced through the filling pipe 5, the metering valve 51 accurately controls the filling flow of the raw material, the raw material flows into the inner cavity of the cylinder 32 through the leakage groove 52, and then flows into the liquid storage tank 31 through the leakage hole 33, and during the addition of the raw material, the guide pipe 34 is sleeved outside the filling pipe 5, forming a relatively sealed channel, so that the inside of the cylinder 32 and the liquid storage tank 31 is greatly blocked from the outside air, so that the whole process of the raw material from the filling pipe 5 into the liquid storage tank 31 is carried out in a relatively closed environment, thereby avoiding the contact between the raw material and the air, effectively reducing the weight loss caused by the volatility of part of the raw material, ensuring the accuracy of the weighing, and further ensuring the accuracy of the disinfectant solution.

[0035] As the raw material in the liquid storage tank 31 increases, the operation panel on the weighing platform 23 displays the weight of the raw material in real time, and when the weight reaches the specified solution weight, the electric push rod 21 drives the container assembly 3 to descend, so that it is separated from the filling pipe 5. After separation, the sealing plate 36 is reset under the pushing force of the spring 37, and is in close contact with the inner top end of the cylinder 32 again, so that the inner cavity of the cylinder 32 and the liquid storage tank 31 is effectively isolated from the outside, preventing the volatile raw material from overflowing, ensuring the accuracy of the solution ratio and the stability of the disinfectant quality.
