Description

Technical Field

[0001] This utility model belongs to the field of aromatherapy technology, which is applied in homes, cars, offices, etc., and specifically relates to an aromatherapy diffuser. Background Technology

[0002] As people's living standards improve, places with strong odors, such as cars, elevators, or new homes, often have some smell. To improve the air quality inside cars and homes, people usually place solid air fresheners, spray perfumes, or place aromatherapy essential oils to make the car smell pleasant, thereby improving comfort, eliminating fatigue for drivers and passengers, enlivening the atmosphere inside the car, and enhancing driving pleasure.

[0003] Furthermore, the aroma diffusers currently on the market are highly homogenized, mainly consisting of two types of structures. One type involves manually adding essential oils to a basic humidifier to achieve a simple aromatherapy function, but this does not provide continuous fragrance. The other type uses solid fragrance tablets (i.e., fragrance generators) or aroma diffuser bottles as the fragrance source to achieve natural and continuous fragrance diffusion. In both of these structures, regardless of whether liquid or solid is used, when using bottled or canned fragrance sources as refills for the aroma diffuser, these refills are mostly round canisters. However, existing aroma diffusers can only accommodate aroma diffuser canisters of one size, not multiple sizes, which affects the practicality and applicability of the diffuser. Moreover, aroma diffuser canisters are prone to size variations due to manufacturing errors, and there is no corresponding tightening or limiting structure inside the diffuser. When these canisters are installed, smaller ones may become loose or misaligned. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example

[0032] like Figures 1 to 8As shown in this embodiment, the aroma diffuser includes a base 1, an aroma diffuser 2 disposed inside the upper end of the base 1 for containing the aroma-producing substance, and a main unit 3 detachably disposed on the upper end of the base 1 and pressing down on the aroma diffuser 2. The aroma-producing substance contained in the aroma diffuser 2 is preferably a solid perfume paste. The upper end of the base 1 is provided with a receiving groove 10 for containing the aroma diffuser 2. A support frame 4 for supporting the aroma diffuser 2 is slidably disposed in the receiving groove 10. That is, the aroma diffuser 2 is placed on the support frame and can move up and down with the support frame 4. The bottom of the support frame 4 is close to the base 1. An elastic element 5 is provided. The elastic element 5 is used to lift the support frame 4 and the aromatherapy jar upward. During the initial assembly, the elastic element 5 is in the normal state. After the aromatherapy jar 2 is installed in the base 1, the elastic element will be compressed downward due to the gravity of the aromatherapy jar 2. When the main unit 3 is assembled, the main unit 3 will apply a downward force to the aromatherapy jar 2, further compressing the elastic element 5 downward, so that the elastic element 5 is in an elastic compression state, generating upward elasticity, and then cooperating with the main unit 3 to press the aromatherapy jar 2 upward. It can be understood that the elastic element 5 is preferably a spring.

[0033] As described above, a support frame and elastic elements are provided on the base to press the aroma diffuser upwards, so that the base can accommodate aroma diffusers of various heights. This avoids problems such as loosening and misalignment when aroma diffusers of different heights are installed, thus improving the practicality and applicability of the aroma diffuser.

[0034] In one embodiment, such as Figures 3 to 8 As shown, the main unit 3 includes a clamping frame 6 that is detachably connected to the upper end of the base 1 and presses down on the aromatherapy jar 2, a decorative shell 7 that surrounds the outer periphery of the upper end of the clamping frame 6, and an upper cover 70 that is suspended above the upper end of the clamping frame 6 and located inside the decorative shell 7. The decorative shell 7 and the upper cover 70 are both fixedly connected to the clamping frame 6 by screws. The lower end of the clamping frame 6 is detachably engaged with the inner wall of the receiving groove 10 by a screw fastener, which facilitates the disassembly and assembly of the main unit 3 and the base 1, thereby facilitating the replacement or replenishment of the aromatherapy jar 2 inside the base.

[0035] As a preferred option, such as Figures 3 to 8 As shown, the upper end of the aroma diffuser 2 is open, and the lower end of the clamping frame 6 is equipped with an exhaust device 8 located above the aroma diffuser 2. An air inlet 71 is formed between the bottom of the decorative shell 7 and the clamping frame 6, which communicates with the air inlet of the exhaust device 8. An air outlet 72 is formed between the upper end of the decorative shell 7, the clamping frame 6, and the top cover 70, which communicates with the air outlet of the exhaust device 8. Thus, when the aroma diffuses, the exhaust device 8 is turned on to generate suction force. External air flows into the aroma diffuser through the air inlet 71 and flows through the opening at the upper end of the aroma diffuser 2, so that the aroma emitted by the aroma diffuser 2 is carried into the exhaust device 8 by the flowing air and finally flows out from the air outlet 72 at the upper end, achieving the purpose of aroma diffusion. This structure can improve the air flow inside and outside the aroma diffuser and effectively improve the aroma diffusion effect.

[0036] As a preferred option, such as Figures 3 to 8 As shown, in order to achieve the downward pressure on the aroma diffuser 2, a plurality of pressing posts 61 are provided on the inner circumference of the lower end of the pressing frame 6, which press against the upper edge of the aroma diffuser 2. The plurality of pressing posts 61 are preferably distributed in a ring array, so that a circle is formed on the inner circumference of all the pressing posts 61. As long as the outer diameter of the aroma diffuser is not less than the diameter of the circle and not greater than the inner diameter of the receiving groove, it can be placed in the receiving groove 10 for matching and use. That is, the edge of the aroma diffuser is pressed down by the pressing posts within the protrusion width range, so that the pressing posts can be adapted to press on aroma diffusers with different outer diameters, further improving the practicality and applicability of the aroma diffuser. Moreover, the size of the circular hole formed on the inner circumference of the pressing posts 61 can be changed by designing the protrusion width of the pressing posts, that is, the protrusion width of the pressing posts can be designed according to the actual production needs and the range of outer diameters of the aroma diffusers to be adapted.

[0037] As a preferred option, such as Figures 3 to 8 As shown, the outer periphery of the pressing frame 6 is provided with several first through holes 62 that connect the air inlet and air outlet 71 of the exhaust device 8, and the upper end of the pressing frame 6 is provided with several second through holes 63 that connect the air outlet and air outlet 72 of the exhaust device 8; the inner side of the decorative shell 7 is provided with a windproof edge 73 that presses against the upper end of the pressing frame 6 and surrounds the second through holes 63 and the upper cover 70, that is, the windproof edge 73 separates the air inlet 71 and air outlet 72 at the upper and lower ends from each other, so that the air entering the aroma diffuser can only flow outward along the exhaust device 8, the second through holes 63 and the air outlet 72.

[0038] In one embodiment, such as Figures 1 to 3 As shown, the main unit 3 also includes a circuit board 9 located on the upper end of the clamping frame 6. The circuit board 9 is electrically connected to the exhaust device 8. One end of the circuit board 9 is provided with a power interface 91 exposed on one side of the decorative shell 7, which is used to connect to an external power source to provide power to the aroma diffuser. The circuit board 9 is also provided with two power switches 92, and the upper cover 70 is provided with two buttons 93 for pressing the two power switches 92 respectively.

[0039] In another embodiment, such as Figure 3 As shown, the lower end of the circuit board 9 is also provided with multiple LED beads 94 facing the clamping frame 6. The clamping frame 6 is preferably made of light guiding material so that the clamping frame 6 has the function of guiding light, so as to form a ring-shaped lighting effect in the exposed part of the lower end of the clamping frame 6, which improves the overall aesthetics.

[0040] In one embodiment, such as Figures 2 to 6As shown, the bottom of the receiving groove 10 is recessed in the middle and a guide groove 11 is provided. The bottom of the support frame 4 is raised and an annular platform 41 is slidably disposed in the guide groove 11. At least one positioning groove 42 is provided on the annular platform 41. At least one positioning rib 12 is raised on the wall surface of the guide groove 11 and is inserted into the positioning groove 42 in a corresponding manner to prevent the support frame 4 from rotating on its own. The elastic element 5 is disposed between the bottom of the support frame 4 and the bottom of the guide groove 11.

[0041] As a preferred option, such as Figures 2 to 6 As shown, the bottom center of the guide groove 11 has a first boss 13 protruding and located inside the annular platform 41. The upper end of the first boss 13 has a first annular groove 14 recessed, so that a first socket 15 is formed in the middle of the first annular groove 14. The bottom center of the support frame 4 has a second boss 43 protruding and inserted into the first annular groove 14. The lower end of the second boss 43 has a second annular groove 44 recessed, so that a second socket 45 is formed in the middle of the second annular groove 44. The elastic member 5 is fitted outside the first socket 15 and the second socket 45, thereby restricting the elastic member 5 between the first annular groove 14 and the second annular platform 44. The two sockets prevent the elastic member from deflecting and falling off. Furthermore, the engagement of the upper and lower bosses can limit the downward movement of the support frame 4 and the stroke of the elastic member, avoiding the problem of the elastic member being over-compressed and causing failure and damage.

[0042] As a preferred option, such as Figures 2 to 6 As shown, the first set-top 15 has a through hole 16 in the middle, and the bottom of the second set-top 45 has a protruding limiting rod 46 that passes downward through the through hole 16; the bottom of the base 1 has a groove 17 recessed in the middle at the position corresponding to the guide groove 11, and the upper end of the groove 17 has a recessed groove 18 surrounding the limiting rod 46. The limiting rod 46 has an insertion hole 47 in the middle, and the lower end of the limiting rod 46 is detachably provided with a limiting member 48 that is inserted into the insertion hole 47. The lower outer diameter of the limiting member 48 is larger than the outer diameter of the through hole 16, which plays a limiting role, so that the assembled support frame 4 cannot be arbitrarily separated from the base 1 and its upward movement is limited. That is, after the support frame 4 is installed in the receiving groove 10, the limiting member 48 is inserted into the lower end of the limiting rod 46 through the groove 17 opened in the bottom of the base 1, thereby limiting the upward movement of the support frame 4.

[0043] As a preferred option, such as Figures 2 to 6 As shown, the upper end of the support frame 4 is provided with an annular anti-slip pad 40 to increase the friction between it and the aromatherapy jar, and the outer periphery of the support frame 4 is provided with a limiting edge 49 surrounding the aromatherapy jar 2 to achieve circumferential limiting.

[0044] In another embodiment, such as Figures 2 to 6As shown, several first air inlets 19 communicating with guide grooves 11 can also be opened at the top of slot 17. After the elastic element lifts the support frame 4, gaps are formed between the support frame 4 and the bottom and wall surfaces of the receiving groove, so that air can be drawn in from the bottom of the base when the exhaust device 8 is working. Several second air inlets 20 communicating with guide grooves 11 are provided through the support frame 4, and anti-slip pads 40 are arranged around the second air inlets 20. In this way, a closed aroma diffuser can be installed in the aroma diffuser for use. Only the upper and lower ends of the aroma diffuser are opened with air holes. When the aroma diffuser contains fragrance beads or ring-shaped aroma diffuser tablets, under the action of the exhaust device, the air at the bottom enters the aroma diffuser upward along the first air inlets 19 and the second air inlets 20, comes into contact with the fragrance substance, and then flows upward, further expanding the types of aroma diffusers that the aroma diffuser can be adapted to.

[0045] In other embodiments, the ventilation device is preferably a fan.

[0046] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
