It has been widely used in various occasions such as homes, hotel rooms, lobbies, corridors, and cars.

[0003] In the prior art, the atomization methods of fragrance devices are mainly divided into ultrasonic atomization and pneumatic atomization. Among them, the ultrasonic atomization method is more widely used due to its simple structure and easy automatic control.

DETAILED DESCRIPTION

[0035] The technical scheme of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the utility model and implement it, but the examples given are not intended to limit the utility model. In the present embodiments, it should be understood that the orientations or positional relationships indicated by terms such as "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", and "outside" are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the utility model.

[0036] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used in this utility model are for illustrative purposes only.

[0037] This embodiment provides a fragrance machine, such as Figures 1 to 8As shown, it includes a shell 1 and a bottle body 2 with an accommodating cavity 3 arranged therein, an atomizing head assembly, a power module 4 and a control module 5 are arranged in the shell 1, the power module 4 is electrically connected to the control module 5, the atomizing head assembly is connected to the bottle body 2, the atomizing head assembly includes a liquid guide core rod 6, an atomizing sheet 7, an atomizing seat 9 and a sleeve 10, the atomizing sheet 7 is electrically connected to the control module 5, the atomizing seat 9 is connected to the bottle body 2, the power module 4 and the control module 5 are connected to the atomizing seat 9 to achieve fixation, and a cavity 3 is formed in the atomizing seat 9. The sleeve 10 is located in the atomizer seat 9 and is connected to and located below the accommodating chamber 3. The housing 1 is provided with a mist outlet 8 facing the atomizer sheet 7. The sleeve 10 is located on the side of the atomizer sheet 7 away from the mist outlet 8. The liquid guide core rod 6 is inserted into the sleeve 10. The first end of the liquid guide core rod 6 is connected to the liquid accumulation space, and the second end of the liquid guide core rod 6 is in contact with the atomizer sheet 7. The liquid fragrance in the liquid accumulation space flows from the first end of the liquid guide core rod 6 to the second end of the liquid guide core rod 6, and then is atomized by the atomizer sheet 7 and then dispersed into the air from the mist outlet 8. Among them, the atomizer seat 9 and the sleeve 10 can be an integrally formed structure or a split connection structure.

[0038] The fragrance machine of the utility model is provided with an atomizer seat 9 with a liquid accumulation space, and a sleeve 10 is provided in the atomizer seat 9. The first end of the liquid guiding core rod 6 is communicated with the liquid accumulation space, and the second end of the liquid guiding core rod 6 is abutted against the atomizer sheet 7. By inserting the liquid guiding core rod 6 into the sleeve 10, the liquid pressure on the surface of the liquid guiding core rod 6 can be reduced, thereby reducing the liquid fragrance flowing to the second end of the liquid guiding core rod 6, avoiding excessive liquid fragrance flowing to the second end of the liquid guiding core rod 6, and making it difficult for the liquid fragrance in the liquid accumulation space to leak out of the mist outlet 8, thereby reducing leakage.

[0039] In a preferred embodiment, a first partition 13 is provided in the atomizer seat 9 and is located above the sleeve 10. The first partition 13 separates an upper cavity 17 and a lower cavity in the atomizer seat 9, that is, the upper cavity 17 is above the first partition 13, and the lower cavity is below the first partition 13. The upper cavity 17 and the lower cavity are connected, and the sleeve 10 and the liquid-conducting core rod 6 are located in the lower cavity. By setting the first partition 13, the sleeve 10 and the liquid-conducting core rod 6 are set in the lower cavity, which can further reduce the liquid pressure on the surface of the liquid-conducting core rod 6.

[0040] Specifically, the first end of the sleeve 10 (i.e., the end away from the atomizer sheet 7) is embedded in the inner wall of the atomizer seat 9 at a preset depth, thereby fixing the sleeve 10, and an elastic member 11 is provided in the sleeve 10, one end of the elastic member 11 abuts against the first end of the liquid guiding core rod 6, and the other end abuts against the first end of the sleeve 10 or the inner wall of the atomizer seat 9 directly facing the first end of the sleeve 10, and the liquid guiding core rod 6 is slidably connected to the sleeve 10, so that the elastic deformation of the elastic member 11 can ensure that the liquid guiding core rod 6 vibrates in coordination with the high-frequency vibration of the atomizer sheet 7, and an opening 12 is provided on the tube wall of the sleeve 10 for liquid fragrance to flow into the sleeve 10. Of course, in order to ensure the stability of the sleeve 10, a structure that can be embedded in the inner wall of the atomizer seat 9 can also be provided at the second end of the sleeve 10 (i.e., the end close to the atomizer sheet 7), so that a supporting force can be formed at both ends of the sleeve 10, thereby improving the stability of the sleeve 10. Preferably, the opening 12 is located directly above the elastic member 11 and extends axially to the first end of the liquid-conducting core rod 6, ensuring the filling and smoothness of the liquid fragrance at the first end of the liquid-conducting core rod 6. The radial gap between the liquid-conducting core rod 6 and the sleeve 10 should not be too large. This not only ensures the directional stability of the liquid-conducting core rod 6 during axial vibration, but also avoids excessive liquid fragrance being filled in the gap, which would create resistance to the vibration of the liquid-conducting core rod 6 and cause leakage. The gap is preferably 0.1 mm.

[0041] Furthermore, a second partition 14 extending radially is provided on the peripheral surface of the sleeve 10, and the peripheral side of the second partition 14 is connected to the first partition 13 and the inner wall of the atomizer seat 9, dividing the lower cavity into a first cavity 15 and a second cavity 16. The first partition 13 is provided with a first through hole 18, and the second partition 14 is provided with a third through hole 20. The first through hole 18 connects the upper cavity 17 and the first cavity 15, so that the liquid fragrance in the upper cavity 17 flows into the first cavity 15 through the first through hole 18. The third through hole 20 connects the first cavity 15 and the second cavity 16, so that the liquid fragrance can flow from the first cavity 15 to the second cavity 16.

[0042] Furthermore, the first partition plate 13 is further provided with a second through hole 19 . The first through hole 18 and the second through hole 19 are respectively located on two sides of the second partition plate 14 . The second through hole 19 communicates with the upper cavity 17 and the second cavity 16 .

[0043] When the aroma diffuser of this embodiment is in atomizing operation, since the bottle body 2 is inverted, there will be a cavity filled with air at the top of the accommodating chamber 3, and liquid fragrance is below the cavity. The liquid fragrance flows into the upper cavity 17 of the atomizing seat 9 and merges into the first cavity 15 through the first through hole 18. After passing through the tube wall of the sleeve 10, it contacts the first end of the liquid guiding core rod 6, and is then attracted to the second end of the liquid guiding core rod 6 for atomization. As the liquid fragrance in the first cavity 15 is continuously atomized, the liquid fragrance in the accommodating chamber 3 will also continuously flow into the first cavity 15 as a supplement, thereby forming a flow, and the gas outside the aroma diffuser will enter the atomizing seat 9 through the atomizing sheet 7 and the liquid guiding core rod 6, and be mixed in the liquid fragrance. The gas mixed in the liquid fragrance will gradually move to the cavity above the accommodating chamber 3. In order to replenish the space for the consumed liquid fragrance and ensure that the cavity is at a positive pressure, the present embodiment sets a second partition plate 14, a second through hole 19 and a third through hole 20, which can promote the gas mixed with the liquid fragrance in the first cavity 15 to first pass through the third through hole 20 into the second cavity 16, and then pass upward through the second through hole 19 to enter the upper cavity 17, and then continue to move upward to the cavity. This can avoid the formation of counter-turbulence between the upward-flowing gas and the downward-flowing liquid fragrance, and can achieve a smooth internal circulation of the gas flow and the liquid fragrance flow, which not only provides a smoother channel for the gas flow, but also provides conditions for the smooth flow of liquid fragrance, so that a stable reflux effect can be formed, thereby ensuring the continuity and stability of the atomization process. The second partition 14 also has a certain blocking effect, which can prevent the gas in the second cavity 16 and the liquid flavor flowing from the upper cavity 17 into the first cavity 15 from mixing with each other, and can further promote the formation of a stable reflux. Preferably, the peripheral side of the second partition 14 is tightly matched with the first partition 13 and the inner wall of the atomizer seat 9.

[0044] As described above, the first through hole 18 and the second through hole 19 need to have a preset spacing distance to avoid convection. In order to ensure sufficient fluidity of the liquid flavor, the opening size of the first through hole 18 is usually larger than that of the second through hole 19. Figure 6 and Figure 7 As shown, the first through hole 18 extends inward from the edge of the first partition 13, thereby increasing the opening size of the first through hole 18; to ensure smooth airflow backflow, the second through hole 19 is preferably located directly above the second cavity 16, with a diameter of not less than 1.5 mm.

[0045] Specifically, the number of the third through holes 20 is not less than one, and they are arranged at intervals in the lower half of the second partition 14, so that the liquid fragrance in the first cavity 15 can only pass through the lower half of the second partition 14, and the upper half of the second partition 14 acts as a baffle to block the liquid fragrance in the first cavity 15 from passing through the upper half of the second partition 14. Compared with the case where the third through holes 20 are distributed in both the upper and lower halves of the second partition 14, this can prevent the liquid fragrance flowing into the upper half of the second partition 14 from hindering the rise of the gas from the lower half. At the same time, compared with the case where the third through holes 20 are distributed only in the upper half of the second partition 14, it can provide a path space for the rise of the gas, avoid stagnation, and make the reflux smoother and more stable; as an example:

[0046] The third through hole 20 is provided with one and is located at the lower half of the second partition plate 14;

[0047] Alternatively, a plurality of third through holes 20 are provided and spaced apart in the lower half of the second partition plate 14;

[0048] Or, if Figure 5 As shown, three third through holes 20 are provided on the second partition plate 14 , one of the third through holes 20 is located at the middle of the bottom of the second partition plate 14 , and the other two third through holes 20 are located in the middle of the second partition plate 14 and on both sides of the liquid-conducting core rod 6 .

[0049] The number of the third through holes 20 is determined by the atomization amount and the cross-sectional area of ​​the second partition 14. Since the liquid fragrance has a certain viscosity, in order to ensure that the liquid fragrance can smoothly pass through the third through holes 20, further, the diameter of the third through holes 20 is not less than 1 mm.

[0050] In another preferred embodiment, the sleeve 10 is further provided with a third partition 21 extending radially thereof on the circumferential surface between the atomizing sheet 7 and the second partition 14, and the circumferential side of the third partition 21 is connected to the inner wall of the atomizing seat 9, and a cavity A 161 is formed between the third partition 21 and the second partition 14, and a cavity B 162 is formed between the third partition 21 and the atomizing sheet 7, and the cavity A 161 and the cavity B 162 are isolated, and the first partition 13 is further provided with a second through hole 19, and the second through hole 19 connects the upper cavity 17 and the cavity A 161.

[0051] In this embodiment, by providing the third partition 21, the liquid fragrance flowing from the first cavity 15 can be sealed in the A cavity 161, and the atomizer sheet 7 can be separated from the A cavity 161, so as to prevent the liquid fragrance in the second cavity 16 from directly contacting the atomizer sheet 7 and causing a large amount of leakage. Preferably, the peripheral side of the third partition 21 is tightly matched with the inner wall of the atomizer seat 9. Further, the sleeve 10, the second partition 14 and the third partition 21 are preferably an integrally formed component, which is easy to process and can also reduce the assembly process. The material is preferably fluororubber.

[0052] Based on the above-mentioned fragrance machine, preferably, the atomizer seat includes a main body 901 and a mist outlet head 902 detachably connected to the main body 901, the sleeve 10 is arranged in the main body 901, the atomizer sheet 7 is fixed between the main body 901 and the mist outlet head 902, and the mist outlet head 902 is provided with a mist outlet channel 903, one end of the mist outlet channel 903 faces the atomizer sheet 7, and the other end is connected to the mist outlet 8. In this embodiment, the atomizer seat includes a main body 901 and a mist outlet head 902, and the mist outlet head 902 is detachably connected to the main body 901. Such a structural design can facilitate the installation of the sleeve 10 and the atomizer sheet 7.

[0053] Furthermore, an annular first groove 22 is provided between the body 901 and the mist outlet head 902, a sealing ring 23 is provided in the first groove 22, and an annular second groove 24 is provided in the sealing ring 23, and the periphery of the atomizing sheet 7 is embedded in the second groove 24. In this embodiment, by providing the sealing ring 23, the liquid fragrance accumulated in the B cavity 162 can be sealed in the B cavity 162, and leakage caused by the liquid fragrance flowing out of the atomizing sheet 7 and the liquid fragrance accumulated on the atomizing seat can also be avoided. The material of the sealing ring 23 is preferably silicone.

[0054] In a specific embodiment, Figure 6As shown, the first groove 22 is an annular U-shaped groove, and the sealing ring 23 is a U-shape matching the first groove 22. The outer side surfaces of the sealing ring 23 are tightly matched with the surfaces corresponding to the first groove 22, that is, the radial cross-section of the sealing ring 23 includes a bottom side, a first side side, and a second side side, wherein the second side side is closer to the mist outlet head 902 than the first side side. Preferably, in order to avoid the influence of the difference in plane flatness or processing error on the sealing effect, the bottom side, the first side side, and the second side side are all tightly matched through a convex structure to achieve the purpose of sealing. Specifically, the body 901 is provided with an annular first protrusion 25 on the surface facing the first side, and the bottom side of the sealing ring 23 is provided with an annular second protrusion 26. The sealing ring A third annular protrusion 27 is provided on the second side of 23. By tightly fitting the first protrusion 25, the second protrusion 26 and the third protrusion 27 with the corresponding mating surfaces respectively, a good sealing effect can be achieved. Compared with the structural method of using a larger plane to fit the seal, this can reduce the matching area between the outer side surface of the sealing ring 23 and the corresponding surface of the first groove 22. A tight fit can be achieved through a smaller matching surface, avoiding the reduction of the sealing effect due to the difference in flatness or processing errors. At the same time, through this combination of raised structure design, not only can the sealing ring 23 and the main body 901 be conveniently integrated into one piece, but also the difficulty of the molding of the sealing ring 23 and the main body 901 will not be increased.

[0055] like Figure 8 As shown, the sealing ring 23 is provided with a first notch 28, and the atomizer seat is provided with a second notch 29. The power cord 30 connected to the atomizer sheet 7 passes through the first notch 28 and the second notch 29 in sequence and then goes out of the atomizer seat. In this way, the sealing performance of the sealing ring 23 is not damaged, and the contact between the liquid fragrance and the power cord 30 is avoided, thereby ensuring the sealing of the power cord 30 and meeting the routing requirements of the power cord 30.

[0056] Furthermore, a seat plate 31 is provided in the housing 1, and the power module 4 and the control module 5 are fixed on both sides of the seat plate 31 in a detachable manner. The seat plate 31 is fixedly connected to the body 901, preferably an integrated structure, which can reduce the number of molds and assembly links, improve production efficiency, and use the two sides of the plate to fix the power module 4 and the control module 5, which can improve the space utilization of the fragrance machine and reduce its external dimensions. Specifically, the material of the seat plate 31 and the body 901 is preferably POM.

[0057] More preferably, the shell 1 includes an upper shell 321, a lower shell and a connecting shell, the connecting shell is fixed on the outer periphery of the main body 901, and the upper shell 321 covers the bottle body 2 and is clamped with the upper end of the connecting shell, so that when the bottle body 2 needs to be replaced, it is only necessary to remove the upper shell 321 to implement the replacement, which is convenient and quick; the lower shell includes a first shell part 33, a second shell part 34 and a third shell part 35, the third shell part 35 is provided with a mist outlet 8, the third shell part 35 is matched with the control module 5, and mist is discharged after the match. The port 8 is docked with the fog outlet channel 903 of the fog outlet head 902. In this embodiment, the control module 5 is provided with a control button 36 and a working status indicator light 37. The third shell 35 is respectively provided with through holes. When the third shell 35 is matched with the control module 5, the control button 36 and the working status indicator light 37 are exposed from the corresponding through holes. After the first shell 33 and the second shell 34 are spliced ​​and connected, the connecting shell, the power module 4 and the control module 5 are covered and the third shell 35 is clamped. During installation, the third shell 35 is first matched with the control module 5, and then the first shell 33 and the second shell 34 are spliced ​​and connected to complete the installation of the lower shell. Specifically, the first shell 33 and the second shell 34 are also fastened by screws after being spliced. When it is necessary to repair the parts in the lower shell, only the first shell 33 and / or the second shell 34 need to be disassembled to expose the parts, which is convenient for maintenance. The structural design of the shell 1 in this embodiment can take into account the convenient replacement of the bottle body 2 and the convenient installation and maintenance of the electronic components, forming a completely wrapped shell structure, which is helpful for the aesthetic design of the appearance and improves the aesthetic appearance of the product.

[0058] It should be noted that the connecting shell of this embodiment is also used to fix the first shell portion 33 and the second shell portion 34 vertically and radially, so as to prevent the first shell portion 33 and the second shell portion 34 from rotating and shaking up and down; Figure 1 and Figure 8 As shown, the connecting shell includes a first shell 38 and a second shell 39, and the first shell 38 and the second shell 39 are spliced ​​and connected, wherein the second shell 39 and the second shell portion 34 are located on the same side.
