Description

Technical Field

[0001] This application relates to the field of aroma diffuser technology, and in particular to a portable aroma diffuser. Background Technology

[0002] Aroma diffusers, also known in the industry as fragrance machines, aroma diffusers, fragrance devices, fragrance systems, fragrance dispensers, aroma diffusers, essential oil diffusers, etc., are products derived from fragrance marketing methods targeting mid-to-high-end users. They are mainly designed for mid-to-high-end business or consumer venues such as star-rated hotel lobbies, chain bars, sales centers, car showrooms, department stores, and clubs. Aroma diffusers atomize essential oils into ultra-fine smoke-like fragrance particles and diffuse them, thereby filling the entire space with a comfortable fragrance.

[0003] Regarding the aforementioned technologies, the inventors believe that when the diffuser is not being used manually, the aroma blocks inside will come into contact with the air and evaporate, thereby accelerating the loss of the aroma and affecting the lifespan of the aroma blocks. Utility Model Content

[0004] The purpose of this application is to provide a portable diffuser to improve the problem that when the diffuser is not in use, the aroma blocks inside will come into contact with the air and evaporate, thereby accelerating the loss of aroma and affecting the lifespan of the aroma blocks.

[0005] This application provides a portable aroma diffuser, which adopts the following technical solution: A portable aroma diffuser includes a housing and a cavity for holding aromatherapy diffusers within the housing. A support base is provided on the inner side wall of the housing below the cavity. A battery is disposed between the bottom of the support base and the housing. A heating coil electrically connected to the battery is provided on the outer side wall of the cavity. An end cap is provided on the top of the housing. The end cap has an air hole communicating with the cavity. A screw cap is rotatably disposed above the end cap to block the air hole.

[0006] By adopting the above technical solution, when the diffuser is in use, the heating coil heats the aroma in the cavity to a certain extent, accelerating the volatilization and diffusion of the aroma, allowing the aroma to diffuse to the outside through the air hole of the end cap; when the diffuser is not in use, the screw cap is rotated to separate the connecting groove from the air hole, sealing the air hole on the end cap, blocking the aroma from the outside air, reducing the loss caused by the long-term contact and volatilization of the aroma with the outside gas, and increasing the use time of the aroma.

[0007] Optionally, the air holes are spaced apart along the radial direction of the end cap, and the screw cap has a communicating groove in the radial direction that communicates with the air holes. When the screw cap rotates, the communicating groove is offset from the air holes so that the screw cap closes the air holes.

[0008] By adopting the above technical solution, the air holes are spaced apart along the radial direction of the end cap, so that the aroma generated by the diffuser can flow to the outside through the air holes when in use. The screw cap has a connecting groove that communicates with the air holes along the radial direction. By rotating the screw cap, the connecting groove can be connected to or offset from the air holes, thereby controlling the opening or closing of the air holes on the end cap.

[0009] Optionally, the vent includes a through hole one and a through hole two opened on the end cap. The diameter of the through hole one is larger than the diameter of the through hole two. The through holes one and two are arranged alternately above the end cap. The connecting groove rotates to a position between the through holes one and two to completely close the through holes one and two.

[0010] By adopting the above technical solution, the air holes include through holes one and two on the end cap. The diameter of through hole one is larger than that of through hole two. Through holes one and two are arranged alternately on the top of the end cap. When the connecting groove is rotated to the position between through holes one and through holes two, through holes one and through holes two can be completely closed. By rotating the connecting groove to the position where it connects with through hole one, the diffusion speed of the aroma of the fragrance is increased.

[0011] Optionally, a filter screen is provided on the side of the end cap facing the housing, which fits against the end cap, and the filter screen corresponds to the air vent.

[0012] By adopting the above technical solution, a filter screen is set on the side of the end cap facing the shell. The filter screen blocks the air holes, reducing the possibility of debris falling into the shell through the air holes and reducing the pollution of the aromatherapy.

[0013] Optionally, a heat insulation pad is provided on the side of the heating coil away from the cavity, and the heat insulation pad extends along the side wall of the support base.

[0014] By adopting the above technical solution, the heat insulation pad extends along the side wall of the support base. When the heating coil slightly heats the aromatherapy placed inside the light body, the heat insulation pad blocks the heat released by the heating coil, minimizing the impact of the heating coil on the shell.

[0015] Optionally, the support base has a ventilation slot that runs through the support base and the heat insulation pad. A fan facing the end cover is provided below the support base at the position of the ventilation slot. The fan is electrically connected to the battery. An air inlet is provided below the housing that communicates with the lower part of the support base. The air inlet is also provided with the filter screen.

[0016] By adopting the above technical solution, the fan installed below the support base blows the aroma of the fixed fragrance in the cavity through the ventilation slot to the air hole of the end cap, which facilitates the rapid diffusion of the aroma. A filter screen is also installed in the air inlet to reduce the possibility of impurities passing through the air inlet and being blown into the cavity by the fan.

[0017] Optionally, the support base is rotatably provided with a partition corresponding to the ventilation slot, and the partition has ventilation holes corresponding to the ventilation slot.

[0018] By adopting the above technical solution, the support base is rotatably connected to a partition corresponding to the ventilation slot via a rotating shaft. Ventilation holes corresponding to the ventilation slot are opened on the partition. The opening and closing of the ventilation slot is controlled by rotating the partition, which facilitates the isolation of the aromatherapy from the outside gas.

[0019] Optionally, the outer wall of the housing is provided with a limiting groove corresponding to the partition, and the partition extends into the inner wall of the limiting groove and is provided with a toggle handle.

[0020] By adopting the above technical solution, the partition is rotated by turning the lever. When the lever abuts against one end of the limiting groove, the ventilation hole and the ventilation groove of the partition are offset and the ventilation groove is closed. When the lever abuts against the other end of the limiting groove, the ventilation hole and the ventilation groove are connected and the ventilation groove is opened, which makes it easier for the diffuser to start the fan to accelerate the diffusion of fragrance when in use.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. When the diffuser is in use, the heating coil heats the aromatherapy in the cavity to a certain extent, accelerating the volatilization and diffusion of the aroma, allowing the aroma to diffuse to the outside through the air hole of the end cap; when the diffuser is not in use, rotate the cap to separate the connecting groove from the air hole, sealing the air hole on the end cap, blocking the aromatherapy from the outside air, slowing down the loss caused by the volatilization of the aromatherapy due to long-term contact with the outside gas, and increasing the lifespan of the aromatherapy. 2. The heat insulation pad extends along the side wall of the support base. When the heating coil slightly heats the aromatherapy placed inside the light body, the heat insulation pad blocks the heat released by the heating coil, minimizing the impact of the heating coil on the shell. 3. A fan located below the support base blows the aroma of the fixed fragrance diffused into the air vents of the end cap through the ventilation slots, facilitating the rapid diffusion of the aroma. A filter screen is also installed in the air inlet to reduce the possibility of debris entering the air inlet and being blown into the cavity by the fan. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 This application will be described in further detail below.

[0025] A portable aroma diffuser, as described above Figure 1 and Figure 2 The device includes a housing 1 and a cavity 2 inside the housing 1 for holding aromatherapy. A support base 11 is fixed to the inner wall of the housing 1 below the cavity 2 with screws. The cavity 2 and the support base 11 are made of metal. A battery 12 is fixed between the bottom of the support base 11 and the housing 1 with screws. A charging port connected to the battery 12 is installed on the outside of the housing 1. An end cap 3 is provided on the top of the housing 1. The housing 1 and the end cap 3 are made of plastic. The bottom of the end cap 3 is threaded to the top of the housing 1. An air hole 31 communicating with the cavity 2 inside the housing 1 is opened on the end cap 3. The end cap 3 is rotatably connected to a screw cap 4 above the end cap 3 via a rotating shaft. By rotating the end cap 3, the air hole 31 is blocked, which isolates the aromatherapy in the housing 1 from the outside world and slows down the loss caused by the aromatherapy evaporating from contact with the outside gas for a long time.

[0026] Reference Figure 2 A heating coil 21 electrically connected to a storage battery 12 is installed on the outer wall of the cavity 2. A switch 6 electrically connected to the heating coil 21 is installed on the outer side of the housing 1. The switch 6 controls the start and stop of the heating coil 21. When the diffuser is in use, the heating coil 21 heats the aromatherapy in the cavity 2 to a certain extent, accelerating the volatilization and diffusion of the aromatherapy. A heat insulation pad 22 is provided on the side of the heating coil 21 away from the cavity 2. The side of the heat insulation pad 22 close to the heating coil 21 is supported and fixed by a metal bracket. The heat insulation pad 22 extends along the side wall of the support base 11. When the heating coil 21 slightly heats the aromatherapy placed inside the cavity, the heat insulation pad 22 blocks the heat released by the heating coil 21, minimizing the impact of the heating coil 21 on the housing 1.

[0027] Reference Figure 1 and Figure 2The air vents 31 are spaced apart along the radial direction of the end cap 3, allowing the aroma produced by the diffuser to flow to the outside through the air vents 31 during use. The screw cap 4 has a communicating groove 41 in the radial direction that communicates with the air vents 31. When the screw cap 4 rotates, the communicating groove 41 is offset from the air vents 31, so that the screw cap 4 closes the air vents 31. The air vents 31 include a first through hole 311 and a second through hole 312 on the end cap 3. The diameter of the first through hole 311 is larger than the diameter of the second through hole 312. The two 312 are arranged alternately above the end cap 3. By rotating the connecting groove 41 to the position of the first through hole 311, the diffusion of the aroma of the fragrance is increased. When the connecting groove 41 is rotated to the position between the first through hole 311 and the second through hole 312, the first through hole 311 and the second through hole 312 can be completely closed. A filter screen 32 that fits against the end cap 3 is fixed with screws on the side of the end cap 3 facing the housing 1. The filter screen 32 corresponds to the air hole 31, reducing the possibility of debris falling into the interior of the housing 1 through the air hole 31.

[0028] Reference Figure 1 and Figure 2 A ventilation slot 111 is provided on the support base 11, penetrating the support base 11 and the heat insulation pad 22. A small-power fan 5 is fixed with screws to the end cover 3 below the support base 11 at the ventilation slot 111. The fan 5 is electrically connected to the battery 12. A switch 7, which is electrically connected to the fan 5, is installed on the outside of the housing 1, and the fan 5 is started and stopped by the switch 7. An air inlet 13 is provided at the bottom of the housing 1, communicating with the bottom of the support base 11. The small-power fan 5 blows the fragrance of the fixed aromatherapy in the cavity 2 through the air hole 31 of the end cover 3, which facilitates the rapid diffusion of the fragrance. A filter screen 32 is also installed in the air inlet 13 to reduce the amount of impurities that are blown out by the fan 5 through the air inlet 13. The cavity 2 is possible; a partition 112 corresponding to the ventilation slot 111 is rotatably connected to the support base 11 via a rotating shaft. A ventilation hole 113 corresponding to the ventilation slot 111 is opened on the partition 112. The opening and closing of the ventilation slot 111 is controlled by rotating the partition 112. A limiting groove 14 corresponding to the partition 112 is opened on the side wall of the housing 1. An integrally formed actuating handle 114 is provided on the inner side wall of the partition 112 towards the limiting groove 14. The partition 112 is rotated by actuating the actuating handle 114. When the actuating handle 114 abuts against one end of the limiting groove 14, the ventilation slot 111 is closed. When the actuating handle 114 abuts against the other end of the limiting groove 14, the ventilation slot 111 is opened.

[0029] The implementation principle of this application embodiment is as follows: In actual operation, after placing the aromatherapy diffuser in the cavity 2, the end cap 3 is threaded to the top of the housing 1. Then, the cap 4 is rotated to connect the connecting groove 41 with the air hole 31. The heating coil 21, which is electrically connected to the battery 12, is activated to slightly heat the aromatherapy diffuser in the cavity 2, causing it to evaporate and produce fragrance. The lever 114 is turned to rotate the partition 112, so that the connecting groove 41 of the partition 112 connects with the ventilation groove 111 of the support base 11. The fan 5 blows the fragrance towards the air hole 31 of the end cap 3, allowing the fragrance to diffuse quickly through the air hole 31. When the diffuser is not in use, the cap 4 is rotated to separate the connecting groove 41 from the air hole 31, sealing the air hole 31 on the end cap 3. The lever 114 is turned to separate the ventilation hole 113 of the partition 112 from the ventilation groove 111, blocking the aromatherapy diffuser from the outside air, reducing the loss caused by prolonged contact with outside gases and extending the lifespan of the aromatherapy diffuser.
