Description

Technical Field

[0001] This utility model relates to the field of aroma diffuser technology, specifically a multi-functional electric aroma diffuser. Background Technology

[0002] Aromatherapy is a fashion, a culture, and a way for people who pursue a high-quality life to find spiritual sustenance. It has the effects of relieving stress and eliminating odors, and is suitable for spaces that need to remove odors, such as homes and offices. To facilitate the diffusion of aromatherapy, a diffuser is usually used.

[0003] Existing diffusers mostly use visible light sources such as halogen lamps or LEDs to heat scented candles. However, once the diffuser is turned on, the light source cannot be turned off separately, which can easily cause light pollution and waste of resources. Some diffusers use fans in conjunction with heating elements such as heating wires to heat scented candles, but this method often cannot control the wind speed and temperature separately, making it inconvenient to use and difficult to meet the needs of modern homes for adapting to multiple scenarios.

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] See appendix Figure 1 - Appendix Figure 3 and appendix Figure 6 This utility model discloses a multifunctional electric aroma diffuser, including a main body 1, a lighting component 2, a fan component 3, and a light-free heating component 4. The main body 1 is used to hold aroma diffusers and is equipped with a control module 11 and a power module 12. The lighting component 2 is connected to the main body 1. The fan component 3 is connected to the main body 1 and is positioned corresponding to the aroma diffuser, and the diffusion speed of the aroma diffuser can be controlled by adjusting the fan speed. The light-free heating component 4 is connected to the main body 1 through a distance adjustment component 5, which can adjust the distance between the light-free heating component 4 and the aroma diffuser, thereby adjusting the temperature of the aroma diffuser by adjusting the distance or its own temperature. The lighting component 2, fan component 3, and light-free heating component 4 are all electrically connected to the control module 11 and the power module 12, so that the lighting component 2, fan component 3, and light-free heating component 4 can be turned on and off independently.

[0053] In actual use, the aroma diffuser is placed on the main body 1 and powered by the power module 12. The control module 11 controls the switching of the fan assembly 3 and the lightless heating assembly 4 to control the diffusion speed of the aroma diffuser. When it is necessary to enhance the atmosphere or provide lighting, the lighting assembly 2 can also be turned on. Since the lighting assembly 2, fan assembly 3, and lightless heating assembly 4 can all be switched on and off independently, the temperature and wind speed can be controlled individually, thereby controlling the diffusion speed of the aroma diffuser through at least one of temperature and wind speed. The light source can also be switched on and off independently to eliminate light pollution. In addition, since the distance adjustment assembly 5 can adjust the distance between the lightless heating assembly 4 and the aroma diffuser, the lightless heating assembly 4 can adjust the temperature of the aroma diffuser by adjusting the distance between it and the aroma diffuser or by adjusting its own temperature. It can also be adjusted to fit aroma diffusers of different sizes. In general, by controlling the individual switching of the lighting assembly 2, fan assembly 3, and lightless heating assembly 4, this multi-functional electric aroma diffuser can meet the needs of various scenarios.

[0054] It should be noted that since this application uses the wind force generated by the fan assembly 3 and the heat radiation generated by the lightless heating assembly 4 to control the diffusion speed of the aromatherapy, when using the aromatherapy with a flame, it is not necessary to light the aromatherapy with a flame, so as to avoid the fan assembly 3 blowing out the flame.

[0055] See appendix Figure 1 and attached Figure 4 In order to protect the aromatherapy and facilitate the functioning of the fan assembly 3 and the lightless heating assembly 4, the following design was not carried out in this embodiment. Specifically, the main body 1 includes a base 13 and a protective cover 14, which are detachably connected. The base 13 is used to place the aromatherapy. The fan assembly 3 and the lightless heating assembly 4 are both located inside the protective cover 14. The protective cover 14 is provided with an air outlet 15 for diffusing the aromatherapy.

[0056] With the above structural design, the cover 14 can be removed from the base 13 when placing the aromatherapy diffuser, and then the cover 14 can be installed back on the base 13 after the aromatherapy diffuser is placed, thus protecting the aromatherapy diffuser; since the fan assembly 3 and the light-free heating assembly 4 are both located inside the cover 14, that is, in a semi-enclosed space, the heat generated by the light-free heating assembly 4 is more concentrated and less likely to dissipate, resulting in a better heating effect and higher thermal efficiency for the aromatherapy diffuser; in addition, since the aromatherapy diffuser, fan assembly 3 and light-free heating assembly 4 are all covered by the cover, the appearance of the multi-functional electric aroma diffuser is also more neat.

[0057] It should be noted that this application does not limit the shape, material, size, color, or other parameters of the base 13 and the cover 14, so they can be designed flexibly according to actual needs. For example, the material of the base 13 and the cover 14 can be high-temperature resistant PC.

[0058] See appendix Figure 1 Appendix Figure 4 and attached Figure 11 There are various ways to detach the base 13. In order to prevent the base 13 from falling off accidentally during the gripping process of the protective cover 14, the following design is made in this embodiment. Specifically, the detachable connection between the base 13 and the protective cover 14 adopts a damped plug-in connection.

[0059] By aligning the connecting parts of the cover 14 and the base 1 and applying force in the direction of mutual proximity, the two can be connected and fixed together; by applying force in the direction of mutual distance, the two can be connected and fixed together. This structure is not only simple and reliable, but also easy to disassemble and assemble, thus facilitating the placement of aromatherapy products.

[0060] See appendix Figure 4 and attached Figure 11 Furthermore, to facilitate understanding of the connection structure between the base 13 and the cover 14, the following design is implemented in this embodiment. Specifically, the top of the base 13 is provided with a vertical first slot 101, and the first slot 101 is provided with at least one first positioning groove 102 and at least one first limiting protrusion 103. The bottom of the cover 14 is provided with a first plug-in 1411 corresponding to the first slot 101, a first positioning protrusion 1412 corresponding to the first positioning groove 102, and a first limiting groove 1413 corresponding to the first limiting protrusion 103. When the cover 14 is connected to the base 13, the first plug-in 1411 is inserted into the first slot 101. At the same time as insertion, the first positioning protrusion 1412 also enters the first positioning groove 102, thereby aligning the first limiting groove 1413 and the first limiting protrusion 103 with each other. When the first limiting protrusion 103 enters the first limiting groove 1413, the connection between the cover 14 and the base 13 is completed.

[0061] It should be noted that, in order for the first limiting protrusion 103 to enter the first limiting groove 1413, at least one of the base 13, the first connector 1411 and the first limiting protrusion 103 should be made of a deformable material or structure, such as an arc-shaped structure made of PC material, and the cross-section of the first limiting protrusion 103 should be arc-shaped.

[0062] See appendix Figure 9 and attached Figure 11 Furthermore, the cover 14 can be divided into a detachably connected lower cover 141 and an upper cover 142. Similarly, the lower cover 141 and the upper cover 142 are connected with damped insertion and removal. Specifically, the lower cover 141 is basically hemispherical and has a second slot 1414 at the top. The second slot 1414 has at least one second positioning protrusion 1415 and at least one second limiting protrusion 1416. The upper cover 14 is basically hemispherical and has a second connector 1421 corresponding to the second slot 1414 and a corresponding second positioning protrusion 1416 at the bottom. The second positioning groove 1422 of 415 corresponds to the second limiting groove 1423 of the second limiting protrusion 1416. When the lower cover 141 and the upper cover 142 are connected, the second plug 1421 is inserted into the second slot 1414. At the same time as insertion, the second positioning protrusion 1415 will also enter the second positioning groove 1422, so that the second limiting protrusion 1416 and the second limiting groove 1423 are aligned with each other. When the second limiting protrusion 1416 enters the second limiting groove 1423, the connection between the lower cover 141 and the upper cover 142 can be completed.

[0063] Furthermore, chamfers may be provided at the bottom of the first connector 1411 and the second connector 1421 to make it easier for the first connector 1411 to enter the first slot 101 and for the second connector 1421 to enter the second slot 1414.

[0064] Furthermore, the damped plug-in connection can still be performed even after the corresponding slots and plugs, and the corresponding protrusions and slots are interchanged.

[0065] See appendix Figure 1 In order to facilitate the wide diffusion of aromatherapy, the following design is made in this embodiment: Specifically, the air outlet 15 is set obliquely upward in the direction of its extension to the outside of the cover 14.

[0066] The above structure allows the aroma to diffuse upwards, and under the influence of gravity, the aroma that has diffused upwards will automatically diffuse downwards, resulting in a faster diffusion speed and a wider diffusion range.

[0067] Furthermore, this application does not limit the shape, size, tilt angle, or other parameters of the air outlet 15, so it can be designed flexibly according to actual needs. For example, the air outlet 15 can be designed as a ring, with an area accounting for 40-60% of the top surface area of ​​the cover 14, and a tilt angle of 25-35°.

[0068] See appendix Figure 2 In order to realize the relevant functions of each component, the following design was carried out in this embodiment. Specifically, the lighting component 2 is a light strip with adjustable color temperature and brightness; the fan component 3 is a brushless DC silent fan; and the lightless heating component 4 is a ceramic heating lamp.

[0069] Based on the above scheme, this embodiment further designs the parameters of each component. Specifically, for the lighting component 2 using light strips, the color temperature adjustment range is 2700K-6500K, and the brightness supports stepless dimming; for the fan component 3 using a brushless DC silent fan, it includes a brushless DC motor 32 and a turbine fan blade 33, with a speed range of 300-2000rpm and a noise level ≤25dB, resulting in lower noise; for the non-light heating component 4 using ceramic heating lamps, the operating temperature range is 80-120℃, and the power is 110-120V 50W, which is safer and more energy-efficient than traditional halogen lamps, with a lifespan extended to about 10,000 hours, eliminating the need for frequent bulb replacements.

[0070] See appendix Figure 5 and attached Figure 8 In order to prevent the disassembly and assembly of the base 13 and the protective cover 14 from affecting the electrical connection between the fan assembly 3 and the control module 11, the following design is made in this embodiment. Specifically, the fan assembly 3 is electrically connected to the control module 11 in the base 13 through the first metal contact 31.

[0071] The above structural design avoids the connection of wires affecting the disassembly and assembly of base 13 and cover 14, and also avoids the clutter caused by excessively long or numerous guides, making the product appearance simpler and more beautiful.

[0072] It should be noted that the base 13 should also have a second metal contact 104 corresponding to the first metal contact 31. The second metal contact 104 is electrically connected to the control module 11. After the base 13 is connected to the cover 14, the second metal contact 104 can abut against the first metal contact 31 so that the fan assembly 3 can be electrically connected to the control module 11.

[0073] See appendix Figure 1 Appendix Figure 2 and attached Figure 10To facilitate the disassembly and assembly of the lightless heating component 4, the following design is implemented in this embodiment. Specifically, the distance adjustment component 5 includes a cover plate 51, the main body 1 is hollow, the lightless heating component 4 and the aromatherapy are both located inside the main body 1, the top of the main body 1 is provided with a first through hole 16, the top of the first through hole 16 is provided with an annular groove 17, the cover plate 51 can be placed on the annular groove 17 and cover the first through hole 16, the distance adjustment component 5 is set on the cover plate 51, and the cross-sectional dimension of the lightless heating component 4 is smaller than the dimension of the first through hole 16.

[0074] With the above structural design, the lightless heating component 4 can be easily removed from the first through hole 16 on the main body 1, making it easy to disassemble and replace the lightless heating component 4.

[0075] See appendix Figure 1 - Appendix Figure 3 To achieve distance adjustment between the lightless heating component 4 and the aromatherapy diffuser, the following design is implemented in this embodiment: Specifically, a second through hole 52 is provided in the middle of the cover plate 51. The distance adjustment component 5 also includes a wire 53 and a single-hole spring buckle 54. The wire 53 passes through the second through hole 52 and its two ends are respectively connected to the lightless heating component 4 and the control module 11. The single-hole spring buckle 54 is located above the cover plate 51 and is passed through by the wire 53. The cross-sectional dimension of the single-hole spring buckle 54 is larger than the dimension of the second through hole 52. The single-hole spring buckle 54 has a first state of clamping the wire 53 and a second state of releasing the clamp. When the single-hole spring buckle 54 is in the first state and abuts against the cover plate 51, it can limit the lightless heating component 4. When the single-hole spring buckle 54 is in the second state, it can adjust the distance between the lightless heating component 4 and the aromatherapy diffuser.

[0076] With the above structural design, in its natural state, the single-hole spring buckle 54 is in the first state of clamping the wire 53; after pressing the single-hole spring buckle 54, the single-hole spring buckle 54 changes to the second state of releasing the clamp. At this time, the wire 53 can be pulled, thereby changing the distance between the lightless heating component 4 and the aromatherapy. Therefore, the distance adjustment component 5 has a simple structure and is easy to adjust.

[0077] Furthermore, in this embodiment, the adjustment range of the distance adjustment component is preferably 0-80mm.

[0078] See appendix Figure 2 and appendix Figure 12 - Appendix Figure 14It should be noted that the above-mentioned single-hole spring buckle 54 is prior art, including a fixing member 541, a moving member 542 and a spring 543. The fixing member 541 is provided with a third through hole 544 corresponding to the second through hole 52 and the wire 53, and a guide hole 545 passing through one side of the third through hole 544. The side of the moving member 542 is slidably connected to the guide hole 545 and its two ends are respectively located inside and outside the third through hole 544. The two ends of the spring 543 abut against the inner wall of the fixing member 541 and the moving member 542 respectively. The moving member 542 is also provided with a fourth through hole 546 corresponding to the second through hole 52 and the wire 53 for the wire 53 to pass through. In use, the wire passes through the third through hole 544 and the fourth through hole 546. In the natural state, the spring 543 will press against the moving member 542, thereby making the single-hole spring buckle 54 clamp the wire 53 and be in the first state.

[0079] In order for the control module 11 to control the lighting component 2, fan component 3, and lightless heating component 4 to be switched on and off individually, the following design is made in this embodiment. Specifically, the control module 11 has multiple working modes, including the first mode, which enables the lighting component 2 alone; the second mode, which enables the fan component 3 alone for aroma diffusion; the third mode, which enables the lightless heating component 4 alone for aroma diffusion; the fourth mode, which enables both the lighting component 2 and fan component 3 simultaneously; the fifth mode, which enables both the lighting component 2 and lightless heating component 4 simultaneously; the sixth mode, which enables both the fan component 3 and lightless heating component 4 simultaneously; and the seventh mode, which enables all three components simultaneously.

[0080] Through the design of the above structure, when the control module 11 adopts the first mode, the multi-functional electric diffuser can be used as a lighting lamp; when the control module 11 adopts the second or third mode, the multi-functional electric diffuser controls the diffusion of aroma with a single variable, resulting in a slower diffusion speed and lower efficiency, with no light pollution; when the control module 11 adopts the fourth mode, the multi-functional electric diffuser controls the diffusion of aroma with two variables, resulting in a faster diffusion speed and higher efficiency, with no light pollution, and the lighting component 2 does not affect the aroma diffusion; when the control module 11 adopts the fifth mode, the diffusion variable, diffusion speed, and diffusion efficiency are all the same as in the second mode, and lighting can be provided or the atmosphere can be enhanced through the lighting component 2; when the control module 11 adopts the sixth mode, the diffusion variable, diffusion speed, and diffusion efficiency are all the same as in the third mode, and lighting can be provided or the atmosphere can be enhanced through the lighting component 2; when the control module 11 adopts the seventh mode, the diffusion variable, diffusion speed, and diffusion efficiency are all the same as in the fourth mode, and lighting can be provided or the atmosphere can be enhanced through the lighting component 2.

[0081] See appendix Figure 1 and attached Figure 7Furthermore, the control module 11 can be switched and the parameters of different components can be adjusted by using button 18. The operation modes of button 18 include rotation, short press, long press, single click, double click, etc. The functions of button 18, such as switch, temperature, wind power, and lighting, can be indicated by UI indicator lights.

[0082] See appendix Figure 1 and attached Figure 3 In order to power the electrical components in the multi-functional electric diffuser, the following design was carried out in this embodiment. Specifically, the power supply module 12 is a plug-in power supply; it is represented by a power cord with a plug in the attached figure. The power input voltage is 80-130V.

[0083] Through the above structural design, this multi-functional electric diffuser has advantages such as safe use, stable power supply, long battery life, and size not affected by the battery.

[0084] See appendix Figure 1 and attached Figure 7 To prevent excessively high temperatures from causing danger or excessively low temperatures from failing to effectively drive aroma diffusion, this embodiment incorporates the following design: Specifically, it includes a temperature sensor 6, which is mounted on the main body 1 and electrically connected to the control module 11. The temperature sensor 6 can monitor the temperature of the lightless heating component 4 in real time and feed the data back to the control module 11 to achieve temperature control. The lightless heating component has three power levels: 100% power (level 1), 75% power (level 2), and 50% power (level 3). When the temperature detected by the temperature sensor exceeds 55°C, the lightless heating component can automatically switch from level 1 to level 3. When level 1 is used for more than 40 minutes, it can automatically switch back and forth between level 1 and level 2 every 30 minutes.

[0085] Furthermore, the temperature sensor 6 mentioned above can be an NTC temperature sensor with an error range of ±1℃.

[0086] Based on the above scheme, the following settings can be made. Specifically, the control module 11 integrates a PID temperature control algorithm and realizes closed-loop control of heating temperature through an NTC temperature sensor, with a control accuracy of ±1.5℃.
