The bottom of the outer circumference of the screw cap 301 is provided with a thread, which is screwed together with the thread at the top of the inner circumference of the base 302, and a sealing gasket 9 (including a radial sealing ring and a plane sealing ring, the radial sealing ring is mounted on the radial groove of the screw cap 301, and the plane sealing ring is installed on the plane of the base 302) is provided therebetween. When the screw cap 301 and the base 302 are screwed together, a plane adhesion force is generated to act on the plane sealing ring to play a sealing role. The top of the screw cap 301 is provided with a screw-on handle 3011 and a middle hole 3012, the base 302 is provided with a hinge structure and is hingedly arranged with the vent buckle 303, the part where the vent buckle 303 and the middle hole 3012 are buckled is the vent shaft 3031, which is constructed as a hollow vent structure, and the vent shaft 3031 is connected to the vent valve 8. As an embodiment of the present invention, the vent valve 8 is designed to include a float valve core 801, a fixing nut 802 and a valve seat 803. The bottom of the inner circumference of the fixing nut 802 is overlapped with the top of the outer circumference of the valve seat 803. Since the top of the inner circumference of the fixing nut 802 is provided with a thread, it is screwed to the outer circumference of the ventilation shaft 3031. A sealing ring is installed between the ventilation shaft 3031 and the fixing nut 802. The float valve core 801 is arranged between the valve seat 803 and the inner wall of the ventilation shaft 3031. When the liquid level in the medicine box 1 rises, the float valve core 801 can resist the ventilation hole on the ventilation shaft 3031.

[0047] In order to prevent fine particles of the liquid medicine from entering the vent valve 8 and the vent buckle 303 and causing blockage, it is necessary to install a barrel filter for filtering. Figure 7 and Figure 8 A circle of stoppers 3021 is provided at the bottom of the inner circumference of the base 302 , and the curled edge of the top of the barrel-shaped filter 10 is placed on the above-mentioned stoppers 3021 , and the edge of the curled edge contacts the inner circumference of the base 302 .

[0049] like Fig.11The liquid level sensor 4 includes a liquid level sensing harness 401, a mounting flange 402, a sensing rod 403 and a float 404. One end of the sensing rod 403 is fixed to the mounting flange 402. The mounting flange 402 is fixed to the outer shell of the medicine box 1 and is located around the first connecting hole 101. The mounting flange 402 and the outer shell of the medicine box 1 are sealed with a sealing pad. The other end of the sensing rod 403 is inserted into the interior of the medicine box 1 through the first connecting hole 101. A float 404 is sleeved on the sensing rod 403. The sensing rod 403 is equipped with a distributed magnetic induction coil to generate different resistance values. The float 404 is equipped with a strong magnet. When the float 404 slides on the sensing rod 403, the corresponding position on the sensing rod 403 is magnetically induced. At this time, the corresponding part of the sensing rod 403 generates corresponding resistance value and voltage value and outputs a signal, which is further converted to obtain a liquid level reading.

[0050] like Figure 12-14The agitator 5 includes a stirring tube 501, a first sealing ring 502, a nozzle body 503, an inner nut cover 504, an outer nut cover 505, a second sealing ring 506, an inner thread adapter 507, a right angle adapter 508, a G1 / 4 connector 509 and a high-pressure water inlet hose 510. One end of the stirring tube 501 is trumpet-shaped, and the middle part thereof is a hollow structure, and both are placed in the medicine box 1. The other end thereof is an outer thread connection part 50101, and the outer thread connection part 50101 passes through the first sealing ring 502, the second connection hole 102 and the inner nut cover 504 and is axially locked with the outer nut cover 505. The nozzle body 503 is a hollow structure, one end of which is closed and a hole is opened at the axial position of the end face of the end, and a ceramic nozzle 11 is inlaid. The middle section of the nozzle body 503 is constructed with an O-ring groove 5031 and a retaining edge 5032, and an O-ring is inserted into the O-ring groove. After 5031, the nozzle body 503 is axially inserted into the interior of the external threaded connection part 50101 of the stirring tube 501 until the rib 5032 contacts the end face of the external threaded connection part, and the external nut cover 505 is matched with the external threaded connection part 50101 of the stirring tube 501 and tightened until its stop ring is pressed against the outside of the rib 5032. The other end of the nozzle body 503 is constructed with an external thread, which is axially screwed with the internal thread adapter and sealed with a second sealing ring 506. The other end of the internal thread adapter 507 is connected to the right-angle adapter 508, and the right-angle adapter 508 is screwed with the G1 / 4 connector 509. One end of the high-pressure water inlet hose 510 is connected to the G1 / 4 connector 509, and the other end is connected to a liquid pump or a valve, which can introduce high-pressure water flow and spray it from the ceramic nozzle 11 to the horn end of the stirring tube 501 until the inside of the medicine box 1. The agitator 5 is a jet flow agitator. After a relatively high-pressure water flow is ejected from the ejection port into the interior of the medicine box 1, a negative pressure zone will be generated in the hollow portion in the middle of the agitator tube 501 to guide the surrounding liquid to flow in continuously and then ejected under the drive of a high-speed jet, thereby forming a circulating flow of the liquid in the medicine box 1 and realizing the function of mixing and stirring. The agitator 5 is installed close to the bottom of the medicine box 1 to continuously flush the bottom of the medicine box 1, thereby slowing down and reducing the sedimentation rate of the mixture, so that the concentration of the mixed liquid in the medicine box is uniform.

[0051] The liquid level tube 6 is a transparent rubber tube, and both ends of the tube are equipped with hinge joints 601. The interior of the hinge joint 601 is hollow, and one end is constructed as a toothed rod 6011 and is sleeved with the transparent rubber tube, and the other end is constructed as a ball head 6012 with a double-pass structure. After the hollow bolt 12 passes through the ball head 6012 and penetrates the corresponding small hole, it is locked with a locking nut 13. A sealing ring 14 is provided between the head of the hollow bolt 12 and the ball head 6012, and between the locking nut 13 and the outer wall of the corresponding small hole.

[0052] Working principle of the present invention:

[0053] First, inject the liquid medicine into the top mounting hole (i.e., the dosing port) of the medicine box 1, then install the base 302, then turn the screw-on handle 3011, screw the screw cap 301 and the base 302 together, cover the vent buckle 303, and buckle the vent shaft 3031 of the vent buckle 303 onto the middle hole 3012 of the screw cap 301, and connect it to the vent valve 8. As the liquid level in the medicine box 1 changes, the float 404 slides on the sensing rod 403 to give a liquid level reading, and the staff can also observe the liquid level in the box through the transparent liquid level tube 6. When the liquid level rises, the float valve core 801 can press against the vent hole on the vent shaft 3031 to completely seal the inside of the medicine box. The high-pressure water inlet hose 510 introduces high-pressure water flow from an external liquid pump or valve, and is sprayed from the ceramic nozzle 11 to the horn end of the stirring tube 501 and even into the medicine box 1. The hollow middle part of the stirring tube 501 will produce a negative pressure zone to guide the surrounding liquid to flow in continuously and then be sprayed out under the drive of a high-speed jet, thereby forming a circulating flow of liquid in the medicine box 1 and realizing the function of mixing and stirring. The agitator 5 is installed close to the bottom of the medicine box 1 to continuously flush the bottom of the medicine box 1, thereby slowing down and reducing the sedimentation rate of the mixture, so that the concentration of the mixed liquid in the medicine box is uniform.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
