[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-6 The utility model provides a quantitative automatic liquid adding device: it includes a cache cylinder 1 and a timing quantitative mechanism 4, the outer surface of the cache cylinder 1 is fixedly connected with an input pipe 2, the top surface of the cache cylinder 1 is fixedly connected with a sealing top cover 3, the inner surface of the sealing top cover 3 is provided with a timing quantitative mechanism 4, and the bottom surface of the cache cylinder 1 is provided with an output bifurcation mechanism 5. Liquid is input into the cache cylinder 1 through the input pipe 2 and output to the output bifurcation mechanism 5 through the timing quantitative mechanism 4.

[0023] Furthermore, the input pipe 2 penetrates to the inner surface of the cache tube 1 .

[0024] Furthermore, the timing and quantitative mechanism 4 includes a knob 401, a threaded shaft 402, a rotating platform 403, a curved pipe 404, a fixed pipe 405 and a connecting port 406. The top surface of the sealing top cover 3 is slidably connected to the knob 401, the bottom surface of the knob 401 is fixedly connected to the threaded shaft 402, the bottom surface of the threaded shaft 402 is rotatably connected to the rotating platform 403, the bottom surface of the rotating platform 403 is fixedly connected to the curved pipe 404, the inner surface of the curved pipe 404 is slidably connected to the fixed pipe 405, and the outer surface of the fixed pipe 405 is provided with a connecting port 406. Through the arrangement of the knob 401, the threaded shaft 402, the rotating platform 403, the curved pipe 404, the fixed pipe 405 and the connecting port 406, during use, the curved pipe 404 and the fixed pipe 405 form a U-shaped pipe, and water is continuously injected into the cache cylinder 1 through the input pipe 2. When the water level does not exceed the top of the curved pipe 404, the cache cylinder 1 is normal. The container cannot output liquid. When the water level exceeds the curved pipe 404, the liquid at the highest point will flow to the opening of the curved pipe 404 under the action of gravity. As a result, negative pressure is generated in the U-shaped tube composed of the curved pipe 404 and the fixed pipe 405. By utilizing the siphon principle, the liquid in the buffer cylinder 1 is continuously sucked into the U-shaped tube and then flows out from the bottom of the curved pipe 404. Since the curved pipe 404 can pass through and slide in the buffer cylinder 1, and the fixed pipe 405 can pass through and slide in the curved pipe 404, the knob 401 rotates the threaded shaft 402 to move vertically through the threaded connection and pull the curved pipe 404 up. By raising the position of the curved pipe 404, the height of the U-shaped tube can be changed to control the maximum water level. In this way, when the input pipe 2 continues to inject liquid into the buffer cylinder 1, the maximum storage capacity can be changed by changing the height of the U-shaped tube composed of the curved pipe 404 and the fixed pipe 405, thereby achieving the effect of outputting liquid from the bottom at a time and in a fixed quantity.

[0025] Furthermore, the threaded shaft 402 passes through the sealing top cover 3 and is threadedly connected to the sealing top cover 3, the curved pipe 404 passes through the cache tube 1 and is slidingly connected to the cache tube 1, and the knob 401 rotates the threaded shaft 402 to move vertically through the threaded connection and pull the curved pipe 404 up. By raising the position of the curved pipe 404, the height of the U-shaped tube can be changed to control the maximum water level.

[0026] Furthermore, the fixed pipe 405 penetrates the inner surface of the curved pipe 404 and is slidably connected to the curved pipe 404. The fixed pipe 405 is fixedly connected to the inner surface of the cache tube 1. The fixed pipe 405 has a longer size and can move inside the curved pipe 404. When the curved pipe 404 is raised, a part of the fixed pipe 405 will still be inside the curved pipe 404 to form a U-shaped pipe.

[0027] Furthermore, the output bifurcation mechanism 5 includes a tension spring 501, a mounting platform 502, a meshing gear 503, a support frame 504 and a three-way pipe 505. The bottom surface of the cache cylinder 1 is fixedly connected to the tension spring 501, the bottom surface of the tension spring 501 is fixedly connected to the mounting platform 502, the outer surface of the mounting platform 502 is rotatably connected to the meshing gear 503, the other end of the meshing gear 503 is fixedly connected to the support frame 504, and the inner surface of the support frame 504 is fixedly connected to the three-way pipe 505. The setting of the channel 505, during use, the tension spring 501 is connected to the mounting platform 502 so that it can adapt to the height position of the curved pipe 404. After the timing and quantitative mechanism 4 outputs liquid to the bottom, the liquid will be diverted through the three-way pipe 505. The three-way pipe 505 is made of rubber and has a certain elasticity. The opening and closing angle of the output end of the three-way pipe 505 is controlled by rotating the support frame 504. The support frame 504 is connected by a meshing gear 503. When one side of the support frame 504 is rotated, the other side is driven to rotate synchronously through gear meshing to ensure centering, so that the output angle can be freely controlled when outputting liquid.

[0028] Furthermore, the number of tension springs 501 is two and they are symmetrically distributed, the number of meshing gears 503 on each side of the mounting platform 502 is two and they are symmetrically distributed, the meshing gears 503 on each side are meshed with each other, the symmetrically arranged tension springs 501 disperse the force support on both sides to make it more stable, and the meshing gears 503 can open and close synchronously through the meshing effect.

[0029] Furthermore, the three-way pipe 505 is made of rubber, and the top surface of the three-way pipe 505 is fixedly connected to the inner surface of the curved pipe 404. The liquid is diverted through the three-way pipe 505 to control the output angle of the fluid. After the fluid is bifurcated, it is ensured that no fluid drips at the bottom center, which can be used to place other devices.

[0030] Working principle: A device for automatic quantitative liquid addition. During use, the knob 401 rotates the threaded shaft 402, which moves vertically through the threaded connection and pulls the curved pipe 404 up. The height of the U-shaped tube can be changed by raising the position of the curved pipe 404. Water is continuously injected into the buffer tube 1 through the input pipe 2. When the water level exceeds the curved pipe 404, the liquid at the highest point will flow out to the bottom of the curved pipe 404 under the action of gravity. The height of the U-shaped tube can be changed by raising the position of the curved pipe 404 to control the highest water level. After the timing and quantitative mechanism 4 outputs the liquid to the bottom, the liquid will be diverted through the three-way pipe 505. The opening and closing angle of the output end of the three-way pipe 505 is controlled by rotating the support frame 504 to control the fluid output angle, thereby completing a device for automatic quantitative liquid addition.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these implementation rules without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
