[0015] The following further describes the present utility model in detail with reference to the drawings. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] As Figures 1-4As shown in the figure, a rapid leak detection device for nasal spray production includes a detection cover plate 1, a detection base 2, a mounting cross frame 3, a cylinder 4, and support feet 5. The detection cover plate 1 covers the detection base 2. The cylinder 4 is installed on the mounting cross frame 3. The mounting cross frame 3 is located above the detection cover plate 1. The piston rod of the cylinder 4 is fixedly connected to the detection cover plate 1. The support feet 5 are arranged at the bottom of the detection base 2. A leak detection groove 11 is provided on the detection base 2. Two rotating rollers 12 are installed in the leak detection groove 11. A nasal spray bottle 18 is placed between the two rotating rollers 12. The two rotating rollers 12 are driven by a transmission mechanism to be connected to a motor 16 installed on a mounting frame 17 outside the detection base 2. A display groove 9 made of a transparent material is provided at the bottom of the leak detection groove 11. The display groove 9 is designed to protrude downward from the leak detection groove 11. A liquid discharge plug 13 is provided at the lowest position of the display groove 9. A cover cavity 14 corresponding to the position of the leak detection groove 11 is provided on the detection cover plate 1. An air joint 10 is provided on the cover cavity 14. The air joint 10 is connected to a vacuum pump through a trachea. Sealing soft pads 15 are provided on the outer surfaces of the cover cavity 14 that are in contact with the detection base 2.

[0017] Further, as Figure 2 and Figure 3 shown in the figure, multiple leak detection grooves 11 arranged in a row are provided inside the detection base 2. Corresponding cover cavities 14 are provided on the detection cover plate 1. A pair of rotating rollers 12 are provided in each leak detection groove 11. An air joint 10 is provided at the upper end of each cover cavity 14. A sealing soft pad 15 is provided on the outer surface of each cover cavity 14 that is in contact with the detection base 2.

[0018] Further, as Figure 1 and Figure 2 shown in the figure, the transmission mechanism includes a friction driving wheel 6, a friction driven wheel 7, and a friction transmission wheel 8. The friction transmission wheel 8 is installed on the motor shaft of the mounting frame 17. The friction driving wheel 6 and the two friction driven wheels 7 are installed outside the detection base 2. The two friction driven wheels 7 are respectively installed on the outer end shafts of the two rotating rollers 12. The friction driving wheel 6 is in close contact with the two friction driven wheels 7, and the friction driving wheel 6 is arranged to drive the two friction driven wheels 7 to rotate through friction when it rotates. The friction transmission wheel 8 is in close contact with the friction driving wheel 6, and the friction transmission wheel 8 is arranged to drive the friction driving wheel 6 to rotate through friction when it rotates. The two rotating rollers 12 rotate to drive the nasal spray bottle 18 placed on them to roll, so that the liquid inside the nasal spray bottle can reach all positions. If there is damage, it will leak quickly due to the internal and external pressure difference, and thus be detected.

[0019] Further, the outer sides of the friction driving wheel 6, the friction driven wheel 7, and the friction transmission wheel 8 are made of rubber materials to increase the friction between them and avoid relative sliding.

[0020] Working principle: Place the nasal spray bottle 18 to be detected between the two rotating rollers 12 of the leak detection tank 11. The rotation of the rotating rollers 12 drives the rotation of the nasal spray bottle 18, so that the liquid reaches all positions inside the bottle body. After placement, the cylinder 4 drives the detection cover plate 1 to cover on the detection base 2, and at the same time, the leak detection tank 11 is fitted and sealed through the sealing soft pad 15. The inside is evacuated to a negative pressure by a vacuum pump, causing a pressure difference between the inside and outside of the nasal spray bottle 18. The internal pressure is greater than the external pressure. When the internal liquid passes through defects such as cracks, the liquid can flow out at an accelerated speed. The flowing liquid converges at the position of the indicating groove 9. Whether there is leakage is judged by observing whether there is liquid at the collecting groove 9, and thus the damaged products are eliminated.

[0021] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
