[0034] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0035] An air freshener that improves the sealing performance of a nozzle, such as Figures 1 to 7As shown, it includes a bottle 1 and a nozzle 2 installed at the bottle mouth of the bottle 1, a straw 3 is provided at the lower part of the nozzle 2, and the lower end of the straw 3 extends into the bottom of the inner cavity of the bottle 1, and is characterized in that: a leak-proof mechanism is provided between the nozzle 2 and the bottle 1, and the leak-proof mechanism includes a leak-proof shell 4, a fixed clamping component 5, a movable clamping component 6 and a locking component. The upper part of the leak-proof shell 4 is connected to the nozzle 2, and the lower part of the leak-proof shell 4 is connected to the bottle mouth of the bottle 1. The interior of the leak-proof shell 4 is provided with a mounting chamber 41 and a sealing chamber 42, and a mounting plate 43 is provided between the mounting chamber 41 and the sealing chamber 42. The mounting chamber 41 is located above the mounting plate 43, and the sealing chamber 42 is located at the mounting chamber 41. Below the plate 43, the mounting plate 43 is provided with a through-hole connecting the mounting chamber 41 and the sealing chamber 42, the straw 3 is inserted into the through-hole, a slide groove 44 is provided on one side of the leak-proof shell 4, the slide groove 44 is connected with the mounting chamber 41, the fixed clamping assembly 5 is fixedly mounted on the upper part of the sealing plate, and the movable clamping assembly 6 is rotatably mounted on the upper part of the sealing plate, the through-hole is located between the fixed clamping assembly 5 and the movable clamping assembly 6, the first end of the movable clamping assembly 6 moves toward and away from the fixed clamping assembly 5, the second end of the movable clamping assembly 6 passes through the slide groove 44 and protrudes from the outer side surface of the leak-proof shell 4, and the locking assembly is arranged on the leak-proof shell 4 and is locked with the movable clamping assembly 6. The conventional air freshener is sealed only at the nozzle of the spray head, and the air freshener easily leaks out along the straw 3. The air freshener needs to be sealed with the bottle cap during transportation, and easily evaporates during storage. The sealing performance of the spray head 2 is poor. However, the present invention clamps the straw 3 by relative movement between the movable clamping component 6 and the fixed clamping component 5, thereby sealing the straw 3 and preventing the air freshener from leaking out along the straw 3, improving the sealing performance, preventing the air freshener from volatilizing, and facilitating storage after opening. During transportation, the movable clamping component 6 is locked by the locking component to keep the air freshener sealed, without the need for additional sealing with the bottle cap for transportation, and without the need to reinstall the spray head 2 when in use, making it more convenient to use.

[0036] Specifically, if Figure 2 As shown, the movable clamping assembly 6 includes a movable clamping rod 61 and a rod reset member 62. The middle portion of the movable clamping rod 61 is rotatably mounted on the mounting plate 43. The first end of the movable clamping rod 61 movably abuts against the fixed clamping assembly 5. The second end of the movable clamping rod 61 passes through the slide slot 44 and protrudes from the outer side of the leak-proof housing 4. The rod reset member 62 is disposed between the movable clamping rod 61 and the leak-proof housing 4 to achieve rotational reset of the movable clamping rod 61 away from the fixed clamping assembly 5. The rod reset member 62 maintains a distance between the movable clamping rod 61 and the fixed clamping assembly 5, preventing the movable clamping rod 61 from accidentally rotating and causing the straw 3 to be clamped and sealed, thereby improving reliability and stability. When the locking assembly releases the movable clamping rod 61, the rod reset member 62 drives the movable clamping rod 61 away from the fixed clamping assembly 5 to automatically release the seal.

[0037] Specifically, the movable clamping assembly 6 is further provided with a connecting shaft 63, the upper portion of which is provided with a snap-fitting groove, the lower portion of which is provided with a limiting platform 631, the mounting plate 43 is provided with a mounting hole penetrating the mounting plate 43, the connecting shaft 63 is rotatably mounted in the mounting hole, the bottom surface of the movable clamping rod 61 is provided with a rotating hole, the inner wall of the rotating hole is provided with a snap-fitting protrusion, the upper portion of the connecting shaft 63 is inserted into the rotating hole, the snap-fitting protrusion is snap-fitted with the snap-fitting groove, and the limiting platform 631 abuts against the lower portion of the mounting plate 43. During production and assembly, the movable clamping rod 61 is placed on the mounting plate 43, the rotating hole is aligned with the mounting hole, and the connecting shaft 63 is then passed through the mounting hole from bottom to top and inserted into the rotating hole. The connecting shaft 63 is snap-fitted with the movable clamping rod 61 via the snap-fitting protrusion and the snap-fitting groove, which facilitates installation and disassembly, has a simple structure, and is low in cost.

[0038] Specifically, the rack rod reset member 62 includes a torsion spring, which is sleeved on the connecting shaft 63 and located between the movable clamping rod 61 and the mounting plate 43. One end of the torsion spring abuts against the mounting plate 43, and the other end abuts against the movable clamping rod 61. Resetting the movable clamping rod 61 by the torsion spring has a simple structure, low cost, and is easy to install. By changing the installation direction of the torsion spring, the reset direction of the movable clamping rod 61 can be directly changed. When the movable clamping rod 61 is reset toward the fixed clamping assembly 5 by the torsion spring, the clamping seal of the straw 3 can be maintained. When in use, the movable clamping rod 61 is locked by the locking assembly. When the movable clamping rod 61 is reset away from the fixed clamping assembly 5 by the torsion spring, the straw 3 can be prevented from being sealed. When sealing, the movable clamping rod 61 is locked by the locking assembly.

[0039] Specifically, if Figure 7 As shown, the fixed clamping assembly 5 includes a clamping seat 51 and a fixed protrusion 52. The clamping seat 51 is fixedly connected to or formed on the upper portion of the mounting plate 43. The fixed protrusion 52 is formed on the side of the clamping seat 51 facing the straw 3. A movable protrusion 611 is provided on the first end of the movable clamping rod 61 facing the straw 3. Clamping blades 612 are provided on opposite sides of the fixed protrusion 52 and the movable protrusion 611. The fixed protrusion 52 and the movable protrusion 611 increase the clamping angle with the straw 3 to avoid gaps. The clamping blades 612 reduce the contact area with the straw 3, increase pressure, strengthen the clamping force, and further improve the sealing performance.

[0040] Specifically, if Figure 1 and Figure 2As shown, the chute 44 is provided with a sealing strip 45, the first end of which abuts against the second end of the movable clamping rod 61, and an easy-to-pull protrusion 451 is provided on the outer side of the second end of the sealing strip 45. During transportation, the sealing strip 45 blocks the chute 44, thereby preventing the movable clamping rod 61 from moving within the chute 44 and locking the chute 44, thereby improving the sealing reliability during transportation and storage. During use, the sealing strip 45 is torn off by pinching the easy-to-pull protrusion 451, thereby releasing the lock on the movable clamping rod 61.

[0041] Specifically, the outer side surface of the straw 3 is integrally formed with the inner wall of the through-hole, or the straw 3 is adhered and fixed to the inner wall of the through-hole by sealant, thereby avoiding a gap between the straw 3 and the inner wall of the through-hole, preventing the air freshener from overflowing from the straw 3, and further improving the sealing performance.

[0042] Specifically, if Figure 2 As shown, the nozzle 2 includes a nozzle 21, a pump assembly 22, a nozzle seat 23 and an arc-shaped spray pressure rod 24. The pump assembly 22 is fixedly installed at the lower part of the nozzle seat 23. The nozzle 21 is connected to the upper part of the pump assembly 22. The upper end of the suction pipe 3 is connected to the lower part of the pump assembly 22. The first end of the spray pressure rod 24 is hinged to the upper part of the nozzle seat 23. The second end of the spray pressure rod 24 extends to the outer side of the leak-proof shell 4. The middle part of the spray pressure rod 24 is connected to the upper part of the nozzle 21. The outer side surface of the upper portion of the leak-proof housing 4 is provided with a plurality of connecting clips 46, and the inner wall of the lower portion of the nozzle seat 23 is provided with a plurality of connecting slots. Each connecting clip 46 is snap-connected to a corresponding connecting slot. The inner wall of the sealed chamber 42 is provided with an internal thread, and the mouth of the bottle 1 is provided with an external thread. The leak-proof housing 4 is threadedly connected to the bottle 1. An upper sealing gasket 81 is provided between the leak-proof housing 4 and the nozzle seat 23, and a lower sealing gasket 82 is provided between the leak-proof housing 4 and the bottle 1. Because the leak-proof mechanism is located below the nozzle 2, the air freshener does not enter the installation chamber 41. The snap connection between the nozzle 2 and the leak-proof housing 4 facilitates production and assembly, while the air freshener does enter the sealed chamber 42. Therefore, the threaded connection between the leak-proof housing 4 and the bottle 1 improves sealing reliability and facilitates transportation.

[0043] Specifically, if Figures 2 to 6As shown, the locking assembly includes a locking pin shaft 7, a locking spring piece 73 and a spray pressure rod 24. A locking bracket 231 is provided on the upper part of the spray seat 23. The first end of the spray pressure rod 24 is hinged to the locking bracket 231. The second end of the spray pressure rod 24 extends to the side of the movable clamping rod 61. The spray pressure rod 24 and the movable clamping rod 61 are pressed against each other. The locking pin shaft 7 is slidably installed on the locking bracket 231 and passes through the locking bracket 231. A locking protrusion 71 is provided on the side of the locking pin shaft 7 facing the nozzle 21, and a limiting protrusion 72 is provided on the other side. The lower part of the locking spring piece 73 is formed on the locking bracket 231. The upper part of the locking spring piece 73 presses against both sides of the limiting protrusion 72. The locking protrusion 71 is locked with the nozzle 21 to prevent the nozzle 21 from moving downward. The nozzle 21 is locked by the locking pin shaft 7, thereby locking the spray pressure rod 24 to prevent the spray pressure rod 24 from rotating, and then the spray pressure rod 24 presses against the movable clamping rod 61, thereby locking the movable clamping rod 61 to maintain a sealed state. The structure is simple and the cost is low. The movable clamping rod 61 is locked while locking the nozzle 2, thereby improving reliability and stability.

[0044] Specifically, the air freshener is provided with a sealed state and a spray state.

[0045] During storage and transportation, Figure 3 As shown, the spray lever 24 is pressed downward and rotated until the second end of the spray lever 24 is rotated downward to the side of the movable clamping rod 61, and the movable clamping rod 61 is located on the first side of the spray lever 24. The spray lever 24 presses against the movable clamping rod 61, and at the same time, the locking pin shaft 7 is moved, as shown. Figure 5 As shown, the locking protrusion 71 of the locking pin shaft 7 locks the nozzle 21, and a step is provided on the outer side of the nozzle 21. The lower part of the locking protrusion 71 abuts the upper part of the step, thereby limiting the upward movement of the nozzle 21. The locking spring piece 73 abuts the first side of the limiting protrusion 72, locking the locking pin shaft 7 through the locking spring piece 73 to prevent the locking pin shaft 7 from accidentally moving and unlocking. At this time, the first end of the movable clamping rod 61 abuts the fixed clamping assembly 5, and the straw 3 is clamped between the movable frame rod and the fixed clamping assembly 5, and the air freshener enters a sealed state.

[0046] When in use, tear off the sealing strip 45 and move the locking pin shaft 7. Figure 6 As shown, the limiting protrusion 72 presses against the locking spring piece 73, the locking spring piece 73 produces elastic deformation, the locking pin shaft 7 is displaced, and the locking spring piece 73 presses against the second side of the limiting protrusion 72 to lock the locking pin shaft 7 again. At this time, the locking protrusion 71 is separated from the nozzle 21, as shown in FIG. Figure 4As shown, under the action of the pump assembly 22, the nozzle 21 is reset upward, and at the same time, the spray pressure rod 24 is rotated upward and reset. The movable clamping rod 61 is rotated to the second side of the spray pressure rod 24 under the action of the torsion spring, so that the first end of the movable clamping rod 61 is away from the fixed clamping assembly 5, and the air freshener enters the spray state.

[0047] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
