[0002] A spray bottle is a common packaging container, commonly used to store liquid substances such as perfume, cleaning liquid, and lotion. The above solutions need to be stored and used in spray bottles after production. There are many types of existing spray bottles. Although the existing spray bottles are small and easy to carry, due to the high viscosity of the cosmetic liquid inside and the large variety of raw materials in their formulas, after the internal solution is left in the spray bottle for a period of time without use, some substances in the internal solution are prone to condensation and sedimentation, or some solutions will undergo oxidation reactions to form solid impurities attached to the inner wall of the nozzle, which can easily cause the spray head to be blocked during spraying. For this reason, we have proposed a spray bottle with an anti-clogging function. Utility Model Content

DETAILED DESCRIPTION

[0025] 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 embodiments 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.

[0026] See also Figure 1-8 The spray bottle with anti-clogging function includes a pressure head 1, a nozzle 2 and a liquid suction device 3. The pressure head 1 is provided with a liquid guide tube 11 at one end corresponding to the connection of the liquid suction device 3, and the liquid suction device 3 is provided with a connecting hole 13 adapted to be connected to the liquid guide tube 11 at one end corresponding to the connection of the pressure head 1. The liquid guide tube 11 can slide inside the connecting hole 13. The internal space formed by the pressure head 1 and the liquid suction device 3 is provided with a rebound device 5 sleeved on the liquid guide tube 11. The pressure head 1 is provided with a through hole 9 at one end corresponding to the connection of the nozzle 2, and the nozzle 2 is provided with a through hole 9 at one end corresponding to the connection of the pressure head 1 and the nozzle through tube 26 that is sleeved. A limit spring 6 and a ball plug 7 are provided inside the liquid suction device 3. A notch is provided at the end of the pressure head 1 away from the liquid suction device 3, and a limiting ring 10 is provided on the outside of the end of the pressure head 1 corresponding to the connection of the liquid suction device 3. The end of the pressure head 1 away from the liquid suction device 3 is provided with a through hole 9 perpendicular to the liquid guide tube 11, and a decontamination rod 12 is provided at the end of the through hole 9 away from the nozzle 2.

[0027] Furthermore, the nozzle 2 as a whole is a cylinder with a through hole provided around the axis. A limiting ring four 23 is provided at the end of the nozzle 2 facing away from the pressure head 1, and a limiting ring three 21 is provided at the end of the nozzle 2 corresponding to the connection with the pressure head 1. A limiting key block 22 is provided around the limiting ring three 21. The limiting ring four 23 can prevent the nozzle 2 from sliding into the interior of the pressure head 1 as a whole, and the limiting ring three 21 can prevent the nozzle 2 from falling out of the pressure head 1 as a whole. The limiting key block 22 mainly guides when the nozzle 2 slides axially and rotates when positioning.

[0028] Furthermore, the decontamination rod 12 is in the shape of a solid cylindrical rod as a whole, and the axial end of the decontamination rod 12 corresponding to the opening side of the through hole 9 is a conical head. The end of the through hole 9 corresponding to the connection nozzle 2 is provided with a key block slide groove 24 that slides with the limit key block 22, and the end of the through hole 9 facing away from the decontamination rod 12 is provided with a key block limit groove ring 25 that rotates with the limit key block 22. When the pressure head 1 is pressed down, the liquid guide tube 11 will contact the limit spring 6 surface, pushing the limit spring 6 downward to be pressed tightly.

[0029] Furthermore, the end of the liquid suction device 3 corresponding to the connection with the pressure head 1 is provided with a thin columnar ring that is sleeved on the pressure head 1, and the end of the liquid suction device 3 corresponding to the connection with the pressure head 1 is provided with a limiting ring 2 15 that is adapted to the limiting ring 10. The end of the liquid suction device 3 facing away from the pressure head 1 is provided with a thin columnar ring that is sleeved on the bottle body 4 and a liquid suction tube 8 coaxial with the liquid suction device 3. The cooperation between the limiting ring 10 and the limiting ring 2 15 can prevent the pressure head 1 from flying out and always apply pressure to the rebound device 5.

[0030] Furthermore, a connecting hole 13 and a liquid storage hole 14 of different sizes but coaxial are provided inside the liquid aspiration device 3 around the axis. The end of the connecting hole 13 away from the liquid catheter 11 is the liquid storage hole 14, and the end of the connecting hole 13 corresponding to the liquid catheter 11 is provided with a boss, and the end of the liquid storage hole 14 away from the connecting hole 13 is provided with a conical through hole, and a movable ball plug 7 is provided at the end of the liquid storage hole 14 away from the connecting hole 13, and a limit spring 6 is provided at the end of the liquid storage hole 14 corresponding to the connecting hole 13. The ball plug 7 cooperates with the limit spring 6 to seal the lower part of the liquid storage hole 14 or rise upward due to the pressure difference to complete the aspiration of the solution.

[0031] Furthermore, the rebound device 5 is composed of an upper plate surface 16, a spring 17 and a lower plate surface 18. The middle part of the rebound device 5 is a spring 17. The two ends of the spring 17 are respectively welded to the upper plate surface 16 and the lower plate surface 18 with matching holes around the axis. The end of the upper plate surface 16 facing away from the spring 17 is in contact with the inner surface of the pressure head 1, and the end of the lower plate surface 18 facing away from the spring 17 is in contact with the inner surface of the liquid suction device 3. The rebound device 5 is always in a compressed state, which can ensure that the pressure head 1 always rebounds.

[0032] Furthermore, the end of the limit spring 6 facing away from the connecting hole 13 is provided with a spring 20 adapted to the ball plug 7, and the end of the limit spring 6 corresponding to the connecting hole 13 is provided with a limit plate 19 in contact with the inner surface of the liquid storage hole 14. A through hole smaller than the size of the connecting hole 13 is opened at the axis of the limit plate 19, and the limit plate 19 can be in contact with the matching surface of the liquid guide tube 11. The limit spring 6 will fall freely when the pressure head 1 is relaxed for a long time, so that it will contact the ball plug 7, so that the ball plug 7 will contact the bottom surface of the liquid storage hole 14, preventing the solution sucked out from the front from flowing back into the bottle body 4. When the limit spring 6 is pressed down and then relaxed, the pressure difference will cause the ball plug 7 to be sucked upward, and the limit spring 6 can prevent the ball plug 7 from blocking the connecting hole 13.

[0033] Working principle: The spray bottle with anti-clogging function is installed according to the diagram, that is, a limit spring 6 and a ball plug 7 are installed inside the liquid suction device 3, the bottom of the liquid suction device 3 is connected to the bottle body 4 and the liquid suction tube 8, and the liquid suction tube 8 is inside the bottle body 4, and the pressure head 1 is installed on the upper part of the liquid suction device 3. The limiting ring 10 of the pressure head 1 and the limiting ring 2 15 of the liquid suction device 3 are used for limiting. The rebound device 5 is sleeved in the middle part of the pressure head 1 and the liquid suction device 3, and the nozzle 2 is installed at the through hole 9 of the pressure head 1. The cosmetic liquid is injected into the bottle body 4 and the pressure head 1 is pressed downward. At this time, the liquid guide tube 11 presses the limit spring 6 downward, and the limit spring 6 compresses the ball plug 7 so that the ball plug 7 seals the lower part of the liquid storage hole 14. When the pressure head 1 is relaxed, the rebound device 5 pushes up the pressure head 1. At this time, due to the pressure difference, the ball plug 7 rises upward, driving the solution inside the bottle body 4 into the liquid storage hole 14. Repeatedly, it can be sprayed outward from the nozzle 2. When it is not used for a long time, the residual solution will oxidize or precipitate and adhere to the inner wall of the nozzle 2. At this time, the nozzle 2 is rotated so that the limit key block 22 enters the key block slide groove 24, pushing the nozzle 2 inward. The decontamination rod 12 will pass through the interior of the nozzle 2 and push out the oxides or precipitates inside the nozzle 2, thereby preventing clogging by foreign matter.

[0034] 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 embodiments 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.
