DETAILED DESCRIPTION

[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Embodiment 1: The utility model provides a drip-proof filling mechanism for liquid chemical products, such as Figure 1-Figure 5As shown, it includes a tank body 1, a stirring mechanism 2, a drain valve 3, a bracket 4, a mounting seat 5, a filling pipe 6, a connecting pipe 7, a flow control mechanism and a leak-proof mechanism. The upper part of the tank body 1 is provided with a stirring mechanism 2 for mixing the liquid, the bottom of the tank body 1 is provided with a drain valve 3, the right side wall of the lower part of the tank body 1 is provided with a bracket 4, the bottom of the bracket 4 is provided with a mounting seat 5, and the bottom of the mounting seat 5 is provided with a filling pipe 6. The filling pipe 6 and the drain valve 3 are connected and communicated with each other by a connecting pipe 7, and the connecting pipe 7 is inclined with the left side higher and the right side lower, which is conducive to the automatic discharge of the liquid from the tank body 1. The mounting seat 5 is provided with a flow control mechanism, and the flow control mechanism includes a sleeve 8, a spiral blade 9 and a driving mechanism 10. The middle part of the mounting seat 5 is rotatably sleeved with a sleeve 8, and the outer wall of the sleeve 8 is provided with a spiral blade 9. The spiral blade 9 is located in the filling pipe 6, and the outer edge of the spiral blade 9 contacts the inner wall of the filling pipe 6, thereby It is beneficial to control the flow rate of the liquid. A driving mechanism 10 is arranged between the upper end of the sleeve 8 and the mounting seat 5. The driving mechanism 10 is mainly composed of a reduction motor and two bevel gears. The reduction motor is mounted on the mounting seat 5, one of the bevel gears is mounted on the output shaft of the reduction motor, and the other bevel gear is mounted on the upper end of the sleeve 8, and the two bevel gears are meshed with each other. A leak-proof mechanism is arranged between the mounting seat 5 and the sleeve 8. The leak-proof mechanism includes a connecting frame 11, a cylinder 12, a connecting rod 13 and a plug 14. A connecting frame 11 is arranged on the mounting seat 5, and a cylinder 12 is mounted on the connecting frame 11. A connecting rod 13 is connected to the telescopic rod of the cylinder 12, and the connecting rod 13 slides through the sleeve 8. A plug 14 is connected to the lower end of the connecting rod 13, and the outer diameter value of the plug 14 is equal to the inner diameter value of the filling pipe 6, which is beneficial to conveniently block the residual liquid in the filling pipe 6.

[0021] like Figure 4 and Figure 5 As shown, further, the upper part of the plug 14 is a truncated cone-shaped structure with a small upper part and a large lower part. When the plug 14 moves downward and separates from the lower end of the filling pipe 6, it is beneficial for the liquid to be discharged downward. When the plug 14 moves upward and fits with the lower end of the filling pipe 6, it can block some of the residual liquid in the filling pipe 6.

[0022] When it is necessary to fill the liquid inside the tank body 1, the drain valve 3 is opened to discharge the liquid inside the tank body 1 into the filling pipe 6 through the connecting pipe 7, and the cylinder 12 is started to extend its telescopic rod, thereby driving the connecting rod 13 and the plug 14 to extend downward, so that the plug 14 can be separated from the lower port of the filling pipe 6, and the container is placed directly below the filling pipe 6 to achieve the filling of the liquid. By starting the reduction motor, under the transmission action of the bevel gear set, the sleeve 8 and the spiral blade 9 can be driven to rotate synchronously, so that the flow rate of the liquid in the filling pipe 6 can be controlled. When a certain amount of liquid is filled in the container, the cylinder 12 is started to shorten and reset its telescopic rod, so that the connecting rod 13 and the plug 14 can be retracted upward and reset, so that the plug 14 can block the lower port of the filling pipe 6. In this way, the residual liquid in the filling pipe 6 can be blocked in time, which is beneficial to the purpose of preventing the filled liquid from dripping.

[0023] Embodiment 2: Based on Embodiment 1, Figure 1-Figure 4 As shown, a blocking component is also included, which includes a guide nozzle 15, a blocking block 16 and a connecting piece 17. The lower end of the filling tube 6 is threadedly connected and connected to the guide nozzle 15. The inner diameter of the guide nozzle 15 is a structure of large upper part and small lower part, and the inner diameter value of the upper part of the guide nozzle 15 is greater than the inner diameter value of the filling tube 6, which is conducive to draining and exporting the filled liquid. The lower end of the guide nozzle 15 is clamped with the blocking block 16, and the side of the blocking block 16 is connected to the side wall of the guide nozzle 15. The connecting piece 17 is made of flexible rubber material and is easy to use. The top of the blocking block 16 is set to bulge upward, and the bulging part is adapted to the inner diameter of the port of the guide nozzle 15, which is conducive to sealing the guide nozzle 15.

[0024] The guide nozzle 15 is screwed on the lower end of the filling tube 6, so that the discharged liquid can be collected into the container in a columnar shape. When filling is not required, the blocking block 16 is buckled on the lower end of the guide nozzle 15, thereby sealing the guide nozzle 15, which is beneficial to further prevent the residual liquid from dripping and also can prevent dust.

[0025] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
