[0027] Example 1 See also Figure 1-Figure 7 The present invention provides a technical solution: a drip-proof device for filling hypochlorous acid disinfectant, comprising a discharge pipe 1, the discharge pipe 1 comprising a main body 11, the main body 11 being a sleeve structure, with an open top and a partially closed bottom; a discharge portion 13 being connected to the bottom end of the main body 11, the discharge portion 13 communicating with the interior of the main body 11, and of course, the discharge portion is sealedly connected to the bottom end of the main body 11; a liquid inlet 12 being connected to one side of the main body 11, the liquid inlet 12 being used to connect to an external chloric acid disinfectant supply device, that is, to introduce chloric acid disinfectant into the liquid inlet 12 through the external chloric acid disinfectant supply device; and a second control valve 6 being provided on the liquid inlet 12; in addition, the discharge portion 13 and the liquid inlet 12 are both cylindrical structures.

[0028] A valve core 5 is provided inside the main body 11. The valve core 5 is a rotating body structure. The valve core 5 is used to block one end of the liquid inlet 12 connected to the main body 11, that is, the valve core 5 is used to block the part connecting the liquid inlet 12 and the main body 11, and block the chloric acid disinfectant from being discharged into the main body 11.

[0029] An air guide groove 51 is provided on the valve core 5, and the air guide groove 51 passes through the top of the valve core 5; a plurality of first air guide channels 52 are provided on the valve core 5, and the plurality of first air guide channels 52 are evenly distributed along the circumference of the axis of the valve core 5, and the top of each first air guide channel 52 is connected to the air guide groove 51; the bottom end of each first air guide channel 52 passes through the bottom end of the valve core 5, and when the valve core 5 blocks the end of the liquid inlet part 12, the bottom end of each first air guide channel 52 faces the inner wall of the discharge part 13; at the same time, the valve core 5 as a whole has a cylindrical structure, with its upper and lower ends protruding outward, and the bottom end of the valve core 5 is adapted to the discharge part 13.

[0030] The top end of the valve core 5 is fixedly connected to the hollow valve stem 2, and the top end of the hollow valve stem 2 is connected to the external pressure air source through a soft tube; a first control valve 4 is provided on the hollow valve stem 2, and the first control valve 4 is close to the bottom end of the hollow valve stem 2, and the first control valve 4 is located inside the air guide groove 51; the bottom end of the hollow valve stem 2 is adjacent to the bottom of the air guide groove 51, and the bottom end of the hollow valve stem 2 is fixed in the air guide groove 51. The hollow valve stem 2 is sealed with the inner wall of the air guide groove 51, and the hollow valve stem 2 is communicated with the air guide groove 51, and the hollow valve stem 2 is coaxial with the main body 11.

[0031] The anti-drip device further includes a driving mechanism 7 , which is used to drive the hollow valve stem 2 to move along the axis of the hollow valve stem 2 , thereby causing the valve core 5 to separate from the end of the liquid inlet portion 12 .

[0032] The driving mechanism 7 includes a first supporting ring 72 fixed on the inner wall of the main body 11, and a spring 71 is provided between the first supporting ring 72 and the valve core 5. The spring 71 is sleeved on the outside of the hollow valve stem 2. The spring 71 is in a compressed state and is used to press against the valve core 5 and cause the valve core 5 to block the end of the liquid inlet portion 12. The outer fixed sleeve of the hollow valve stem 2 is provided with a moving ring 73. The moving ring 73 is coaxial with the hollow valve stem 2. The moving ring 73 is located above the first supporting ring 72. A spring 71 is coaxially provided on the top of the moving ring 73. Iron ring 74; an adsorption component 76 is provided on the main body 11, and the adsorption component 76 is used to adsorb the iron ring 74; a plurality of rolling members 75 are fixedly provided on the outer ring surface of the movable ring 73, and the rolling members 75 can adopt universal balls 751, and the plurality of universal balls 751 are evenly distributed along the circumference of the axis of the movable ring 73, and the ball head of each universal ball 751 contacts the inner wall of the main body 11; by providing a plurality of universal balls 751, the stability of the movement of the movable ring 73 is improved, thereby helping to improve the stability of the movement of the valve core 5.

[0033] The adsorption assembly 76 includes a second support ring 762 fixed on the inner wall of the main body 11, and the second support ring 762 is located above the iron ring 74; an annular electromagnet 761 is installed at the bottom of the second support ring 762, and the annular electromagnet 761 corresponds to the position of the iron ring 74; in addition, the hollow valve stem 2 passes through the first support ring 72, the iron ring 74, the annular electromagnet 761 and the second support ring 762.

[0034] By energizing the annular electromagnet 761, the annular electromagnet 761 attracts the iron ring 74, and under the guidance of the universal ball 751, the movable ring 73 and the iron ring 74 are prompted to move toward the annular electromagnet 761 until the iron ring 74 is attracted by the annular electromagnet 761, thereby prompting the valve core 5 to move upward and detach from the end of the liquid inlet part 12, and at this time the spring 71 is further compressed.

[0035] In this embodiment, by opening the second control valve 6 and closing the first control valve 4, and energizing the annular electromagnet 761, the annular electromagnet 761 attracts the iron ring 74, thereby driving the valve core 5 upward to a suitable distance, causing the valve core 5 to completely separate from the end of the liquid inlet portion 12. At this time, the chloric acid disinfectant is introduced into the interior of the main body 11 and can be discharged from the drain portion 13, so that filling can be carried out; of course, during the filling process, a portion of the chloric acid disinfectant will flow into the air guide groove 51 and the interior of the hollow valve stem 2 through the first air guide pipe. Since the first control valve 4 Close to the bottom end of the hollow valve stem 2, the bottom end of the hollow valve stem 2 is adjacent to the bottom of the air guide groove 51, and the diameter of the first air guide channel 52 can be set to be smaller to ensure that there is very little chloric acid disinfectant in the first air guide channel 52, the hollow valve stem 2 and the air guide groove 51; after the appropriate filling time, the second control valve 6 is closed in time, and the valve core 5 is driven to reset by the driving mechanism 7, and the valve core 5 re-blocks the drain part 13; thereafter, wait for 1-2 seconds, during which the chloric acid disinfectant in the first air guide channel 52, the hollow valve stem 2 and the air guide groove 51 is facilitated to flow out.

[0036] Then, the first control valve 4 is opened, and at the same time, a pressure air source is introduced into the hollow valve stem 2 through an external pressure air source. The pressure air source flows through the air guide groove 51 and the first air guide channel 52 and is discharged toward the inner wall of the discharge portion 13, thereby facilitating the discharge of a portion of the residual liquid in the first air guide channel 52, the hollow valve stem 2 and the air guide groove 51 into the discharge portion 13. At the same time, it is also convenient to discharge a portion of the residual liquid in the discharge portion 13 and directly fill it into a container such as a filling bottle, thereby reducing liquid residue and achieving an anti-drip effect; of course, through multiple tests in advance, the first control valve 4 can be closed in time within a suitable time range by testing, so that the filling requirements can be met when the residual liquid is blown out by air flow later, thereby avoiding overfilling; finally, the external pressure air source stops introducing air flow into the hollow valve stem 2, and the first control valve 4 is closed. At the same time, the annular electromagnet 761 is powered off, and under the action of the spring 71, the valve core 5 is prompted to reset; through the above operations, the next filling can be carried out.

[0037] In this embodiment, part of the residual liquid is discharged by air flow for direct filling, thereby reducing liquid residue to achieve an anti-drip effect, and also reducing the waste of chloric acid disinfectant.

[0038] Example 2 See again Figure 1-Figure 7 This embodiment is based on the first embodiment, and three second air guide channels 53 are further provided on the valve core 5. The three second air guide channels 53 are evenly distributed along the circumference of the axis of the valve core 5; the top ends of the three second air guide channels 53 are connected to the air guide groove 51, and the three second air guide channels 53 all pass through the valve core 5 and face the bottom inner wall of the main body 11.

[0039] When air flow is introduced into the hollow valve stem 2, a part of the air flow can also be discharged through the second air guide channel 53. The air flow discharged from the second air guide channel 53 hits the bottom wall of the main body 11, and the air flow discharged from the first air guide channel 52 hits the inner wall of the liquid discharge portion 13, thereby generating a reaction force on the valve core 5. Since a spring 71 is provided between the valve core 5 and the first support ring 72, when the upward force applied to the valve core 5 can cause the spring 71 to be further compressed, the valve core 5 can be moved upward. At this time, the air flow discharged through the second air guide channel 53 can also facilitate blowing a part of the liquid residue in the main body 11 into the liquid discharge portion 13, thereby further reducing the liquid residue and improving the anti-drip effect; of course, in this embodiment, through multiple tests in advance, the first control valve 4 can be closed in time within a suitable time range by testing, so that the filling requirements can be met when the liquid residue is blown out by the air flow in the future, thereby avoiding overfilling.

[0040] Example 3 See again Figure 1This embodiment is based on the second embodiment, and two mounting brackets 3 are fixedly provided on the outside of the main body 11. Fixing holes 31 are provided on the mounting brackets 3. The fixing holes 31 facilitate the installation of the mounting brackets 3, thereby facilitating the installation and fixation of the entire device.
