Description

Technical Field

[0001] This utility model belongs to the field of aroma diffuser technology, specifically relating to a high-efficiency drive device for aroma diffusers. Background Technology

[0002] The air pump is the main driving component in an aroma diffuser. The air pump generates a stable airflow, which propels and diffuses the tiny particles or molecules formed by the aroma liquid into the air, allowing the fragrance to permeate the room evenly and quickly and effectively enhance the indoor fragrance effect.

[0003] In existing aroma diffusers, the air pump is usually wrapped with a layer of sound-absorbing cotton during assembly to keep the diffuser operating at low noise. However, many air pumps are secured with tape, cable ties, or hot melt adhesive. While this provides some stability, the cotton's elasticity makes it prone to breaking open, affecting the air pump's sound insulation. Furthermore, there is no spacer between the sound-absorbing cotton and the air pump's terminals. During prolonged operation, the heat generated by the air pump can easily bake or ignite the sound-absorbing cotton. In addition, the stability of the air pump's terminals is crucial for the diffuser's operation. Currently, the most common air pump failure point is a loose or faulty connection at the terminals, leading to intermittent operation or burnout. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency drive device for aromatherapy machines, which can be attached tightly to the surface of the air pump through the flexibility of the sound insulation cotton, thereby providing efficient sound insulation for the air pump.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A high-efficiency drive device for an aromatherapy diffuser includes an air pump and a fixed plate. The fixed plate is annular, and the air pump is located inside the fixed plate. End caps are respectively fitted to the end faces of the fixed plate. First sound-insulating cotton is fixedly connected to the side wall of the fixed plate and the end caps near the air pump. Second sound-insulating cotton is fixedly connected to the inner wall of the first sound-insulating cotton located inside the fixed plate. A protective cover is fitted to the end face of the air pump, and the protective cover penetrates the end caps. A conductive component is provided on the side wall of the protective cover.

[0007] The second sound insulation cotton has a wavy sidewall structure.

[0008] The conductive assembly includes a conductive post fixedly connected to the end face of the protective cover. One end of the conductive post penetrates the protective cover and is fixedly connected to an elastic clip. The elastic clip has a U-shaped structure, and the end face of the elastic clip away from the conductive post is inclined inward.

[0009] Arc-shaped blocks are fixedly connected to the opposite sidewalls of the elastic clips, and the arc-shaped blocks abut against the air pump terminals.

[0010] Each of the conductive posts has through holes on its sidewall.

[0011] The side wall of the fixed plate has two limiting grooves, and an installation ring is slidably connected in the limiting groove. The side wall of the installation ring is threaded with a bolt, and the bolt abuts against the side wall of the limiting groove.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a high-efficiency drive device for an aromatherapy machine.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-7 As shown, a high-efficiency drive device for an aromatherapy diffuser includes an air pump 1 and a fixing plate 2. The fixing plate 2 is annular, and the air pump 1 is located inside the fixing plate 2. End caps 3 are respectively mounted on the end faces of the fixing plate 2. First sound insulation cotton 4 is fixedly connected to the side wall of the fixing plate 2 and the end caps 3 near the air pump 1. Second sound insulation cotton 5 is fixedly connected to the inner wall of the first sound insulation cotton 4 located inside the fixing plate 2. A protective cover 6 is mounted on the end face of the air pump 1. The protective cover 6 penetrates the end cap 3, and a conductive component is provided on the side wall of the protective cover 6.

[0026] like Figure 3 As shown, the sidewall of the second sound insulation cotton 5 has a wavy structure.

[0027] Specifically, the first sound insulation cotton 4 is used for primary sound insulation, and the second sound insulation cotton 5 is used for secondary sound insulation. The second sound insulation cotton 5 corresponds to the rotor position of the air pump 1, and the noise generated during operation is directly transmitted to the second sound insulation cotton 5. Both the first and second sound insulation cottons have numerous tiny pores and channels inside. When sound waves enter the sound insulation cotton, they cause the air in the pores to vibrate. Due to the friction and viscous resistance between the air and the pore walls, the sound energy is continuously converted into heat energy and dissipated. The wavy design further increases the surface area of ​​the sound insulation cotton, allowing more sound waves to enter these pores, thereby improving sound absorption efficiency.

[0028] like Figure 3 and Figure 6 As shown, the conductive assembly includes a conductive post 8 fixedly connected to the end face of the protective cover 6. One end of the conductive post 8 penetrates the protective cover 6 and is fixedly connected to an elastic clip 7. The elastic clip 7 has a U-shaped structure, and the end face of the elastic clip 7 away from the conductive post 8 is inclined inward. An arc-shaped block 10 is fixedly connected to the opposite side wall of the elastic clip 7, and the arc-shaped block 10 abuts against the wiring terminal of the air pump 1.

[0029] The drive structure of the air pump 1 is generally a motor or micro motor, and its wiring terminals adopt a copper sheet structure with holes for easy soldering. In view of this characteristic, this solution improves the structure of the conductive component. The elastic properties of the metal elastic clip 7 are used to clamp the air pump 1 wiring terminal. At the same time, with the cooperation of the arc blocks 10 on both sides, it can be inserted into the hole of the wiring terminal. This can not only increase the connection stability, but also increase the area between the component and the wiring terminal, avoid the phenomenon of loose connection, reduce the failure rate, and thus achieve the effect of high-efficiency drive.

[0030] Each of the conductive posts 8 has through holes 9 on its sidewalls. The through holes 9 facilitate welding with external wires. The wires can be wound inside the through holes 9 before welding, thereby enhancing the stability and strength of the wiring.

[0031] like Figure 1 and Figure 7 As shown, two limiting grooves 11 are provided on the side wall of the fixing plate 2. An installation ring 12 is slidably connected in the limiting groove 11. A bolt 13 is threadedly connected to the side wall of the installation ring 12. The bolt 13 abuts against the side wall of the limiting groove 11.

[0032] Specifically, the mounting ring 12 is an optional option in this solution. It can be used to install and fix the air pump 1 according to the space of the aroma diffuser's housing, thereby effectively improving its practicality and flexibility.

[0033] The working principle of this utility model is as follows: When it is necessary to perform sound insulation treatment on the air pump 1, firstly, the fixing plate 2 is put on the air pump 1 so that the first sound insulation cotton 4 and the second sound insulation cotton 5 are both in contact with the surface of the air pump 1. Then, the protective cover 6 is fixed to one side of the wiring terminal of the air pump 1 with screws so that the elastic clip 7 is inserted into the wiring terminal of the air pump 1. Then, the end cover 3 is connected to the fixing plate 2 with screws to complete the sound insulation treatment of the air pump 1.

[0034] During operation, the first sound insulation cotton 4 and the second sound insulation cotton 5 can reduce the noise of the air pump 1, making the volume generated during operation smaller and improving the user's comfort.

[0035] 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.
