Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, and in particular to an air purifier fragrance module structure. Background Technology

[0002] As people's living standards continue to improve, their requirements for living environments are also increasing. To create a better environment, people commonly use diffusers or aromatherapy diffusers to improve indoor air quality, thereby keeping the air fresh, eliminating odors, and disinfecting. Diffusers or aromatherapy diffusers atomize essential oils, diffusing the fragrance into the air to improve air quality. The atomizing nozzle, as a crucial component of the diffuser or aromatherapy diffuser, needs to ensure stable operation and ease of maintenance.

[0003] To ensure sufficient fragrance diffusion, many fragrance diffusers currently use heating methods to enhance the diffusion effect, such as US Patent No. 8.201.957. However, using resistance heating of essential oils or waxes raises concerns about electrical safety. Existing fragrance diffusers also utilize high-frequency oscillations generated by ultrasonic devices, such as US Patent No. 9.539.355. These diffusers primarily use an oscillator to vibrate liquids to produce fragrance, which is then transported into the external space by a fan. This process breaks down water molecules and dissolved plant essential oils into nano-sized cold mists with diameters of 0.1-5 micrometers, filling the surrounding air with fragrance. However, during ultrasonic oscillation, some energy is converted into heat, which can damage essential oil molecules and affect their natural efficacy.

[0004] Heating and vibration can damage essential oil molecules, affecting their natural efficacy and failing to overcome issues such as insufficient diffusion. Among commonly used air treatment devices, air purifiers are widely used to clean indoor air. They promote air circulation and treat the air, ensuring fresh air is fully diffused throughout the area. Therefore, combining an air purifier with a fragrance generator can solve problems like insufficient diffusion associated with fragrance generators. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] like Figures 1-10 As shown, a fragrance module structure for an air purifier includes a fragrance diffuser holder 8 and an air pump 10 installed on one side of the fragrance diffuser holder 8. A bracket 12 is provided on the outer wall of the fragrance diffuser holder 8, and the air pump 10 is mounted on the bracket 12. A vibration damping pad 11 is installed between the air pump 10 and the bracket 12. An insertion port 13 is machined on the outer wall of the fragrance diffuser holder 8, and the insertion port 13 is connected to the air pump 10 via a fragrance silicone adapter 9. A fragrance sealing ring 5 is embedded in the outer wall of the fragrance diffuser holder 8, which is mainly used to seal the fragrance diffuser holder 8 and the air purifier. Several fixing brackets 14 are machined on the outer wall of the fragrance diffuser holder 8, and the fragrance diffuser holder 8 is mounted on the air purifier via these fixing brackets.

[0030] The aromatherapy holder 8 houses an essential oil bottle 7 and an aromatherapy vaporization device 3 that connects to the essential oil bottle 7. The aromatherapy vaporization device 3 has an inner spiral 18 and an essential oil return port 19 machined inside. An aromatherapy cap 1 is located on the top of the aromatherapy vaporization device 3, and the inner spiral 18 is used to secure the essential oil bottle 7. A groove 17 is machined on the outer wall of the aromatherapy vaporization device 3, and a sealing silicone gasket 4 is installed inside the groove 17 to seal the air pump inlet 15.

[0031] An essential oil connecting pipe 6 is installed between the essential oil bottle 7 and the aroma vaporization device 3. A reflux bracket 2 is installed inside the aroma vaporization device 3. An air pump inlet 15 and an essential oil outlet 16 are machined inside the aroma vaporization device 3. The end of the air pump inlet 15 narrows to form an air outlet 21, and the essential oil outlet 16 narrows to form a vaporization spray nozzle 20. The lower end of the essential oil connecting pipe 6 is inserted into the essential oil bottle 7, and its upper end is inserted into the essential oil outlet 16. A sloping groove 22 is machined at the top of the essential oil outlet 16. The sloping groove 22 has an inclination angle of 30-60 degrees. The entire sloping groove 22 must be fully connected, otherwise it will affect the airflow transmission and thus affect the atomization effect. When the high-pressure gas coming out of the air outlet 21 passes through the sloping groove 22, it will turn upward. When the negative pressure is generated to draw out the essential oil, the essential oil is vaporized and transported upward.

[0032] The top of the essential oil outlet 16 is processed with a vaporization platform 23. The length of the vaporization platform 23 is 1-3mm, the width of the vaporization platform 23 is 1-3mm, and the vaporization platform 23 is a sloping structure. If the vaporization platform 23 is too large or too small, it will affect the atomization effect.

[0033] The diameter of the air outlet 21 is 0.2-0.6 mm, and the depth of the air outlet 21 is 0.2-0.5 mm. The diameter of the vaporization spray nozzle 20 is 0.2-1 mm, and the depth of the vaporization spray nozzle 20 is 0.3-0.6 mm. The distance between the air outlet 21 and the vaporization spray nozzle 20 is 0.2-1.5 mm. The upper part of the air outlet 21 is located above the plane of the vaporization spray nozzle 20, and the lower part of the air outlet 21 is located below the plane of the vaporization spray nozzle 20.

[0034] A raised rubber part 24 is machined on the right side of the vaporization spray nozzle 20 on the vaporization platform 23. The distance between the right edge of the raised rubber part 24 and the right end point of the vaporization spray nozzle 20 is 0.1-1mm. The main purpose of the raised rubber part 24 is to facilitate the smooth withdrawal of the punch during mold production.

[0035] In use, this application involves activating the air pump 10. The high-pressure airflow generated by the air pump 10 instantly enters the air outlet 21 through the air pump inlet 15. When the high-pressure airflow passes through the vaporization spray nozzle 19, it instantly changes the pressure at the vaporization spray nozzle 19, thereby creating a negative pressure that draws the essential oil from the essential oil bottle 7 through the essential oil connecting tube 6. When the essential oil reaches the vaporization spray nozzle 19, it is rapidly atomized under the action of the high-pressure airflow and then enters the air with the airflow. Compared with existing fragrance modules, this application has a simpler overall structure, a more reasonable design, lower production costs, and does not damage the components of the essential oil due to heat. It also has a better atomization effect and better meets people's usage needs.
