[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1 to 10As shown, a car air freshener with easily replaceable fragrance pads includes a rectangular shell 1. A top plate 2 is fixedly connected to the upper surface of the rectangular shell 1. An upper vent 3 is provided inside the top plate 2. A lower vent 4 is provided at the bottom of the rectangular shell 1. A clamp 5 is fixedly connected to the bottom of the rectangular shell 1. First rectangular holes 6 are provided on both the left and right sides of the rectangular shell 1. A first rectangular cylinder 7 is fixedly connected to the inner wall of the first rectangular hole 6. A horizontal plate 8 is attached to the inner wall of the first rectangular cylinder 7. A second rectangular hole 9 is provided inside the horizontal plate 8. A rectangular fragrance pad 10 is adhered to the inner wall of the second rectangular hole 9. A middle vent 1 is provided inside the rectangular fragrance pad 10. 1. A hemispherical groove 12 is provided at the bottom of the horizontal plate 8. A hemispherical block 13 is attached to the inner wall of the hemispherical groove 12. A trapezoidal plate 14 is fixedly connected to the bottom of the hemispherical block 13. A second rectangular tube 15 is fixedly connected to both the front and rear sides of the inner wall of the rectangular shell 1. The inner wall of the second rectangular tube 15 is attached to the surface of the trapezoidal plate 14. A third rectangular hole 16 is provided inside the trapezoidal plate 14. A connecting block 17 is fixedly connected to both the front and rear sides of the inner wall of the second rectangular tube 15. The left and right sides of the connecting block 17 are attached to the inner wall of the third rectangular hole 16. A main spring 18 is fixedly connected to the bottom of the connecting block 17 and the inner wall of the third rectangular hole 16.

[0032] The rectangular aromatherapy pad 10 is located in the middle of the horizontal plate 8. The thickness of the rectangular aromatherapy pad 10 is equal to the thickness of the horizontal plate 8. A positioning groove 19 is provided on the upper surface of the horizontal plate 8. A positioning post 20 is fitted into the positioning groove 19. The upper surface of the positioning post 20 is fixedly connected to the inner wall of the first rectangular tube 7.

[0033] It should be noted that the trapezoidal plate 14 can only move up and down through the second rectangular tube 15. After the hemispherical block 13 is aligned with the hemispherical groove 12 through the main spring 18, the hemispherical block 13 can be in close contact with the hemispherical groove 12. When the hemispherical block 13 is inserted into the hemispherical groove 12, the horizontal plate 8 can be fixed in the rectangular housing 1 through the hemispherical block 13 and the hemispherical groove 12. The car air freshener can be fixed at the air conditioning vent of the car through the clamp 5. When the air conditioning vent of the car blows out, the air outside the rectangular housing 1 enters the rectangular housing 1 through the lower vent 4. Then, the fragrance emitted by the rectangular air freshener 10 is discharged through the upper vent 3 along the airflow. Through the cooperation of the positioning groove 19 and the positioning post 20, when the horizontal plate 8 is inserted into the first rectangular tube 7, it will not be unable to be directly fixed in the rectangular housing 1 because the hemispherical groove 12 is facing upward.

[0034] like Figures 1 to 12As shown, a threaded hole 21 is provided at the bottom of the rectangular shell 1. A sealing plug 22 is threadedly connected to the inner wall of the threaded hole 21. A groove 23 is provided on the upper surface of the sealing plug 22. An auxiliary spring 24 is fitted to the inner wall of the groove 23. A connecting plate 25 is fixedly connected to the bottom of the trapezoidal plate 14. A circular hole 26 is provided inside the connecting plate 25. A U-shaped plate 27 is fixedly connected to the upper surface of the connecting plate 25. The inner wall of the U-shaped plate 27 is fitted to the upper surface of the auxiliary spring 24. The auxiliary spring 24 is located in the circular hole 26. A magnetic block 28 is fixedly connected to the inner wall of the groove 23. The upper surface of the magnetic block 28 is fitted to the bottom of the auxiliary spring 24.

[0035] The centers of the sealing plug 22, the auxiliary spring 24 and the magnetic block 28 are all on the same vertical line, and the magnetic block 28 has a greater attraction force on the auxiliary spring 24 than the weight of the auxiliary spring 24.

[0036] It should be noted that when the auxiliary spring 24 is inserted into the groove 23, the magnetic block 28 can attract the auxiliary spring 24, preventing it from falling out of the groove 23. When the sealing plug 22 is screwed into the threaded hole 21, the auxiliary spring 24 can be fixed in the U-shaped plate 27 through the cooperation of the sealing plug 22 and the threaded hole 21. When the main spring 18 loses elasticity due to metal fatigue, the auxiliary spring 24 can be added in the U-shaped plate 27. The hemispherical block 13 can still be in close contact with the hemispherical groove 12, so that the main spring 18 does not need to be disassembled and replaced after losing elasticity due to metal fatigue. This makes the maintenance of the car air freshener more convenient.

[0037] The working principle of this utility model is as follows: First, insert the horizontal plate 8 into the first rectangular tube 7, and move the horizontal plate 8 so that the left and right sides of the horizontal plate 8 are flush with the left and right sides of the rectangular shell 1. When the left and right sides of the horizontal plate 8 are flush with the left and right sides of the rectangular shell 1, the hemispherical block 13 is aligned with the hemispherical groove 12, and the main spring 18 makes the hemispherical block 13 in close contact with the hemispherical groove 12. At this time, the horizontal plate 8 can be fixed in the rectangular shell 1 through the hemispherical block 13 and the hemispherical groove 12. Then, the car air freshener is fixed at the air conditioning vent of the car through the clamp 5. When the air conditioning vent of the car blows out, the air outside the rectangular shell 1 enters the rectangular shell 1 through the lower vent 4. Then, the fragrance emitted by the rectangular air freshener 10 is discharged through the upper vent 3 along the airflow.

[0038] When it is necessary to replace the rectangular aromatherapy tablet 10, first insert the horizontal plate 8 with the new rectangular aromatherapy tablet 10 into the first rectangular tube 7 on the left. Then, push the new horizontal plate 8 to the right to push the original horizontal plate 8 out of the rectangular shell 1. When the left and right sides of the new horizontal plate 8 are aligned with the left and right sides of the rectangular shell 1, the hemispherical block 13 is aligned with the hemispherical groove 12, and the main spring 18 makes the hemispherical block 13 in close contact with the hemispherical groove 12. At this time, the new horizontal plate 8 can be fixed in the rectangular shell 1 through the hemispherical block 13 and the hemispherical groove 12, and the new rectangular aromatherapy tablet 10 can be fixed in the rectangular shell 1.

[0039] When the main spring 18 loses elasticity due to metal fatigue, first insert the sealing plug 22 into the threaded hole 21, then insert the auxiliary spring 24 into the groove 23, and screw the sealing plug 22 back into the threaded hole 21. At this time, the cooperation between the sealing plug 22 and the threaded hole 21 can fix the auxiliary spring 24 into the U-shaped plate 27, and through the elastic force of the auxiliary spring 24, the hemispherical block 13 can still be in close contact with the hemispherical groove 12.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
