When the air in the water bath 3 is large, the air can enter the annular airbag 30 through the air hole 31, and the annular airbag 30 expands to clamp the glass.

[0031] Circulating flow component; the circulating flow component includes a driving rod 19 that penetrates the equipment box 2 and the water bath box 3 and is rotatably arranged and located in the power chamber 9, a propeller 34 is fixed on the driving rod 19, a motor 20 is fixedly installed on the inner wall of the power chamber 9, and the driving rod 19 is fixedly installed on the output end of the motor 20.

[0032] A non-aggressive heating tube 32 is disposed outside the propeller 34 , and an electric heating wire is embedded in the heating tube 32 , so that the circulating water can be heated; the heating tube 32 is fixedly connected to the inner wall of the water bath 3 through a plurality of short tubes 33 .

[0033] It also includes a supernatant preparation mechanism, which includes a mounting plate 11 fixed to the inner wall of the power chamber 9, a piston cylinder 14 is installed at the bottom of the mounting plate 11, a movable piston 25 is slidably connected to the inner wall of the piston cylinder 14, and a connecting rod 24 is hingedly connected to the bottom of the movable piston 25.

[0034] The liquid inlet pipe 12 and the liquid outlet pipe 13 extend into the supernatant preparation chamber 8, the delivery pipe 7 is connected to the flow equalizing pipe 6, and the delivery pipe 7 is provided with a first liquid outlet electromagnetic one-way valve 15, which allows the fluid in the piston cylinder 14 to flow into the delivery pipe 7, and the liquid outlet pipe 13 is provided with a second liquid outlet electromagnetic one-way valve 17, which allows the fluid in the piston cylinder 14 to flow into the liquid outlet pipe 13; the electromagnetic one-way valve mentioned above is composed of a solenoid valve and a one-way valve.

[0035] The present invention also discloses a method for circulating the supernatant of the collagen-promoting composite acid in a water bath, comprising the following steps: S1, preparation and setup phase: The user opens the upper cover 5, places the glass in the annular airbag 30, and ensures that its bottom is against the inner bottom of the water bath 3, adds clean water to the water bath 3, and then covers the upper cover 5; opens the cover plate 4, mixes the required ingredients according to the specific formula, and adds an appropriate amount of solvent, adds the solution to the supernatant preparation chamber 8, and covers the cover plate 4; S2, start the heating and circulation stage: start the motor 20, the motor 20 drives the driving rod 19 and the propeller 34 to rotate, and generates negative pressure in the heating tube 32, so as to transport and heat the clean water; the heating tube 32 circulates and heats the flowing clean water; S3, liquid mixing and supernatant formation stage: The driving rod 19 rotates through the first gear 21 and the second gear 22 to drive the driving rod 18 and the circular plate 23 to rotate, thereby driving the connecting rod 24 and the movable piston 25 to move up and down. The up and down movement of the movable piston 25 realizes the circulation of the liquid, mixes the liquid, and finally forms a supernatant. In this stage, the first liquid outlet electromagnetic one-way valve 15 is in a closed state; S4, supernatant delivery stage: After a period of time, the second liquid outlet electromagnetic one-way valve 17 is closed, the first liquid outlet electromagnetic one-way valve 15 is opened, and the movable piston 25 continues to reciprocate up and down, and the supernatant is sent out through the delivery pipe 7 and transported to the flow equalizing pipe 6, and then injected into the glass cup through the injection pipe 27 to achieve the addition of the supernatant; S5, glass positioning and steam discharge stage: When the supernatant in the supernatant preparation chamber is evacuated, the movable piston 25 transports air when it moves up and down. The air is transported to the water bath 3 through the delivery pipe 7, the flow equalizing pipe 6 and the injection pipe 27, increasing the pressure in the water bath 3. The air enters the annular airbag 30 through the air hole 31, causing it to expand and clamp the glass. At the same time, as the air pressure in the water bath 3 increases, the air is transported to the water bath water collection chamber 10 through the through hole 29, and the steam treated in the water bath is discharged.

[0036] When in use, the user opens the upper cover 5, places the glass in the annular airbag 30 and makes the bottom touch the inner bottom of the water bath 3, adds clean water into the water bath 3, and then covers the upper cover 5; then opens the cover plate 4, and the user mixes the required ingredients in a certain proportion according to the specific formula, adds an appropriate amount of solvent, adds the solution to the supernatant preparation chamber 8, covers the cover plate 4, and starts the motor 20.

[0037] The motor 20 drives the driving rod 19 to rotate, and the driving rod 19 drives the propeller 34 to rotate. When the propeller 34 rotates, negative pressure is generated in the heating tube 32, so that clean water can be transported through the heating tube 32. The heating tube 32 can be used to heat the flowing clean water, so that the water bath water is heated and circulated to ensure that the temperature of the water bath water flowing outside the glass is uniform, which is beneficial to the water bath treatment of the supernatant.

[0038] The rotation of the driving rod 19 drives the first gear 21 to rotate, the rotation of the first gear 21 drives the second gear 22 to rotate, the rotation of the second gear 22 drives the transmission rod 18 to rotate, the rotation of the transmission rod 18 drives the circular plate 23 to rotate, the rotation of the circular plate 23 drives the connecting rod 24 to move, and the connecting rod 24 drives the moving piston 25 to reciprocate up and down. When the moving piston 25 moves downward, the liquid can be sucked into the piston cylinder 14 through the liquid inlet pipe 12. When the moving piston 25 moves upward, the liquid in the piston cylinder 14 can be squeezed into the liquid outlet pipe 13 and transported to the supernatant preparation chamber 8 to realize the circulation of the liquid. In this way, the liquids can be mixed to finally form a supernatant. It should be noted that the first liquid outlet electromagnetic one-way valve 15 is in a closed state at this time.

[0039] After a period of time, the second liquid outlet electromagnetic one-way valve 17 is closed, and the first liquid outlet electromagnetic one-way valve 15 is opened. When the movable piston 25 moves up and down, the supernatant can be sent out through the delivery pipe 7 and finally delivered to the flow equalizing pipe 6. The supernatant flows through the flow equalizing pipe 6 to multiple injection pipes 27, and finally injected into the glass cup through the injection pipe 27, thereby achieving the mixing and addition of the supernatant without the need for manual personnel.

[0040] When the supernatant in the supernatant preparation chamber 8 is evacuated, the movable piston 25 moves up and down, and air is transported in the piston cylinder 14. The air is transported to the water bath 3 through the delivery pipe 7, the flow equalizing pipe 6 and the injection pipe 27, so that the pressure in the water bath 3 increases. When the air enters the annular airbag 30 through the air hole 31, the annular airbag 30 expands to clamp the glass. In this way, the glass is positioned and is not easily moved, so as to ensure the stability of the supernatant during water bath treatment.

[0041] The cover plate 4 is provided with an opening at the part opposite to the water bath water collection chamber 10. As the air pressure in the water bath box 3 increases, the air is transported to the water bath water collection chamber 10 through the through hole 29, so that the steam treated by the water bath can be discharged to prevent the steam from condensing and falling into the glass again, causing pollution to the supernatant. It should be noted that the air is discharged through the through hole 29 at the beginning. The inner diameter of the through hole 29 is small, and the speed of air discharge is slow. Therefore, the water bath box 3 is in a state greater than the external atmospheric pressure to ensure that the annular airbag 30 is in an expanded state.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
