Detailed implementation mode

[0024] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0025] Refer to Figures 1 to 3 , an aromatherapy machine with a diffusion air duct, comprising a first housing 1 and a second housing 7;

[0026] The first housing 1 has a first cavity 11, the first cavity 11 is provided with an oil bottle assembly 3, above or on the top of the oil bottle assembly 3 is provided with an atomization assembly 2, and the top of the atomization assembly 2 is provided with a mist outlet 221;

[0027] A diffusion air duct 100 is formed between the second housing 7 and the first housing 1, the top of the diffusion air duct 100 is an air outlet 110; the diffusion air duct 100 has an air flow flowing towards the air outlet 110, which can also be understood as an upward - flowing air flow;

[0028] Refer to Figure 2 And Figure 3, it further includes a diffusion component 9, which is arranged above the mist outlet 221 and is roughly located at the air outlet 110; a diffusion surface 90 is provided at the bottom of the diffusion component 9, and the diffusion surface 90 is gradually inclined upward from the middle to the edge. Specifically, the diffusion surface 90 is composed of inclined straight line segments and arc line segments, and the arc line segments are located at the edge, that is, close to the air outlet 110. The inclined straight line segments play a role in guiding the flow, and the arc line segments can cooperate with the wall surface of the air outlet 110 to form a gradually narrowing space, which can promote the accelerated outward flow of the atomized oil liquid and form a certain jet effect.

[0029] Among them, the diffusion component 9 includes a central block 91 and an annular block 92. The bottoms of the central block 91 and the annular block 92 are both gradually inclined upward from the middle to the edge, and the bottoms of the central block 91 and the annular block 92 are smoothly transitioned, which can guide the atomized oil liquid to the air outlet 110.

[0030] Thus, after the oil liquid is atomized, it flows out from the mist outlet 221, then diffuses around through the diffusion surface 90 and flows to the air outlet 110. Then, the air flow in the diffusion air duct 100 blows the atomized oil liquid to the outside, and the diffusion is accelerated by the air flow, and the diffusion is more uniform and faster.

[0031] Reference Figure 2 , the wall surface of the air outlet 110 gradually becomes larger along the air flow direction, which can also be understood as being gradually inclined, forming a structure similar to a flared structure or a horn-shaped structure, which promotes the atomized oil liquid to flow out around, and is more conducive to diffusion around.

[0032] Reference Figure 2 , the fan 8 can be arranged at the top or bottom of the diffusion air duct 100. Preferably, it is arranged at the bottom of the diffusion air duct 100 and hidden inside, which is more beautiful. The fan 8 can form an air flow to accelerate the diffusion in an active manner.

[0033] Reference Figure 2 And Figure 4 , a spoiler 120 is provided near the top of the diffusion air duct 100, for example, arranged near the air outlet 110. The spoiler 120 is inclined, and it can be an inclined surface structure or a three-dimensional arc surface structure, which promotes the air flow to flow upward in a spiral manner, so as to better achieve the effect of uniform blowing and diffusion.

[0034] Reference Figure 5, the atomization assembly 2 includes an atomization core holder 21 and an atomization cover 22. The atomization core holder 21 is provided with a first ventilation channel 211 and a second ventilation channel 212. The first ventilation channel 211 is generally in a right-angled direction. One end of the first ventilation channel 211 can communicate with the first cavity 11, and the other end of the first ventilation channel 211 can communicate with the oil bottle assembly 3. An atomization head 23 is provided at one end of the first ventilation channel 211 close to the oil bottle assembly 3. The atomization head 23 is provided with an oil suction pipe 24, and the oil suction pipe 24 extends towards the bottom of the oil bottle assembly 3; the second ventilation channel 212 is generally vertically arranged. The upper end of the second ventilation channel 212 communicates with the atomization cover 22, and the lower end of the second ventilation channel 212 communicates with the oil bottle assembly 3. The atomization cover 22 is located in the first groove 214 at the top of the atomization core holder 21. An air outlet 221 is provided on the top or upper surface of the atomization cover 22; the oil suction pipe 24 transports the oil liquid to the atomization head 23, and the atomization head 23 atomizes the oil liquid under the action of air flow. The atomized gas flows through the second ventilation channel 212 towards the air outlet 221 and finally flows to the outside.

[0035] Reference Figure 5 And Figure 6 , the atomization assembly 2 is provided with a first clamping mechanism 25 and a second clamping mechanism 26;

[0036] The first clamping mechanism 25 is clamped with the top of the oil bottle assembly 3;

[0037] The second clamping mechanism 26 is clamped with the side wall of the first housing 1 or the first cavity 11.

[0038] Assembly steps: First, the oil bottle assembly 3 is connected to the atomization assembly 2 through the first clamping mechanism 25, so that the oil bottle assembly 3 and the atomization assembly 2 form a whole. Then, the oil bottle assembly 3 and the atomization assembly 2 are placed into the first cavity 11 as a whole, and the atomization assembly 2 is connected to the side wall of the first housing 1 or the first cavity 11 through the second clamping mechanism 26. Thus, through the connection of the clamping mechanism, convenient and rapid assembly is realized.

[0039] Reference Figure 7 , the first clamping mechanism 25 includes a steel ball 251, a sliding sleeve 252 and a first spring 253;

[0040] The atomization assembly 2 includes an atomization core holder 21, and the atomization core holder 21 is provided with an inner cavity 213 capable of accommodating the top of the oil bottle assembly 3;

[0041] A radial hole 2141 capable of accommodating the steel ball 251 is provided on the first cavity wall 214 of the inner cavity 213;

[0042] The sliding sleeve 252 is sleeved on the outside of the first cavity wall 214 in a relatively movable manner;

[0043] The lower end of the sliding sleeve 252 is provided with an inclined surface portion 2521 that is inclined outward;

[0044] The first spring 253 is sleeved outside the first cavity wall 214. The upper end of the first spring 253 is connected to the atomization core holder 21, and the lower end of the first spring 253 is connected to the sliding sleeve 252.

[0045] On the outer side of the top of the oil bottle assembly 3, there is a first card slot 321 that cooperates with the steel ball 251.

[0046] Thus, when assembling the oil bottle assembly 3, first push the sliding sleeve 252 upward to make the inclined surface portion 2521 correspond to the steel ball 251, and the steel ball 251 can move outward. Then, insert the top of the oil bottle assembly 3 into the inner cavity 213 of the atomization core holder 21 to make the first card slot 321 correspond to the steel ball 251. Then, the sliding sleeve 252 can reset under the action of the first spring 253, and the inclined surface portion 2521 pushes the steel ball 251 to connect with the first card slot 321, thereby realizing a snap connection, and both the assembly and disassembly are convenient and fast.

[0047] Reference Figure 8 , the second snap connection mechanism 26 includes a snap connection member 261 and a bracket 262; both the snap connection member 261 and the bracket 262 are generally assembled in the second groove 215 at the top of the atomization core holder 21, and the snap connection member 261 is arranged above the bracket 262;

[0048] The snap connection member 261 is provided with a horizontal arm 2611 and a vertical arm 2612; the horizontal arm 2611 and the vertical arm 2612 are generally arranged perpendicular to each other;

[0049] At the lower end of the vertical arm 2612, there is a buckle portion 2612a;

[0050] On the side wall of the first housing 1 or the first cavity 11, there is a second card slot 110 that cooperates with the buckle portion 2612a;

[0051] During assembly, the convenient and fast assembly and fixation of the atomization assembly 2 are realized through the cooperation of the buckle portion 2612a and the second card slot 110;

[0052] During disassembly, the horizontal arm 2611 can drive the vertical arm 2612 to swing. That is, when pushing the horizontal arm 2611 downward, the horizontal arm 2611 drives the vertical arm 2612 to swing outward during the swinging process, and the vertical arm 2612 can swing to make the buckle portion 2612a disengage from the second card slot 110, thereby realizing convenient disassembly.

[0053] Reference Figure 8 And Figure 9 , at the connection between the horizontal arm 2611 and the vertical arm 2612, there is a rotating shaft portion 2613;

[0054] The bracket 262 is provided with a shaft hole portion 2621 that cooperates with the rotating shaft portion 2613, enabling the horizontal arm 2611 and the vertical arm 2612 to swing around the rotating shaft portion 2613 as the axis or pivot point;

[0055] The side wall of the bracket 262 is provided with a notch portion 2623 that can accommodate the vertical arm 2612, providing space for the connection between the buckle portion 2612a and the second card slot 110;

[0056] The top wall of the bracket 262 is provided with a recessed portion 2622 that can accommodate the horizontal arm 2611. The recessed portion 2622 is inclined, providing space for the swing of the horizontal arm 2611 and limiting the movement range of the horizontal arm 2611 to prevent the swing angle of the horizontal arm 2611 from being too large and breaking;

[0057] Among them, multiple horizontal arms 2611 and vertical arms 2612 can be correspondingly arranged and circumferentially arrayed, making the clamping member 261 in the shape of a ring or sleeve structure; similarly, the bracket 262 is correspondingly provided with multiple shaft hole portions 2621, recessed portions 2622, and notch portions 2623, making the bracket 262 in the shape of a ring or sleeve structure.

[0058] Reference Figure 8 , the second clamping mechanism 26 further includes a second spring 263; the upper end of the second spring 263 is connected to the horizontal arm 2611, and the lower end of the second spring 263 is connected to the bottom of the second groove 215. The second spring 263 can push the horizontal arm 2611 to reset, and is conducive to promoting the stable connection between the buckle portion 2612a and the second card slot 110, preventing disengagement due to vibration.

[0059] Reference Figure 8 , the bracket 262 is connected to the side wall of the second groove 215 through a first buckle 2624; the second clamping mechanism 26 further includes a third spring 264; the upper end of the third spring 264 is connected to the top wall of the bracket 262, and the lower end of the third spring 264 is connected to the bottom of the second groove 215. Thus, the bracket 262 is supported and fixed by the third spring 264, and loosening can be reduced.

[0060] Reference Figure 8 And Figure 9 , the second clamping mechanism 26 further includes a flat plate 260. The flat plate 260 is arranged above the horizontal arm 2611, and a convex portion 2611a is provided at one end of the horizontal arm 2611 away from the vertical arm 2612.

[0061] Thus, by pushing the flat plate 260 downward, the horizontal arm 2611 can be pushed to swing downward, and then the vertical arm 2612 can be driven to swing outward, causing the buckle portion 2612a to disengage from the second card slot 110, unlocking the atomization assembly 2, and the atomization assembly 2 and the oil bottle assembly 3 can be integrally separated from the first housing 1, realizing convenient disassembly.

[0062] Among them, the provision of the convex portion 2611a facilitates the transmission of external force to the horizontal arm 2611, better promotes the swinging of the horizontal arm 2611, and is not likely to interfere with the movement of the horizontal arm 2611.

[0063] Reference Figure 9 , the atomization assembly 2 further includes a side cover 265. The side cover 265 is connected to the bracket 262. The bracket 262 may be provided with a second buckle 2625, and is connected to the side cover 265 through the second buckle 2625;

[0064] The diffusion assembly 9 includes a central block 91 and an annular block 92. The annular block 92 is provided with a space capable of accommodating the central block 91, and the central block 91 and the annular block 92 can move relative to each other; both the central block 91 and the annular block 92 are connected to the atomization assembly 2. Specifically, the central block 91 is connected to the flat plate 260, and the annular block 92 is connected to the side cover 265.

[0065] Thus, by pressing the central block 91, the horizontal arm 2611 can be pushed to swing downward, and then the vertical arm 2612 is driven to swing outward, so that the buckle portion 2612a is disengaged from the second card slot 110, unlocking the atomization assembly 2.

[0066] Preferably, the central block 91 can be integrally formed with the flat plate 260, and the annular block 92 is integrally formed with the side cover 265, which is beneficial to simplifying the structure and facilitating assembly.

[0067] Reference Figure 7 , the atomization assembly 2 further includes a pressure ring 27, a gasket 28 and a fourth spring 29;

[0068] The pressure ring 27 is arranged in the inner cavity 213. A gasket 28 is provided at the bottom of the pressure ring 27. A fourth spring 29 is provided between the atomization core holder 21 and the pressure ring 27. The fourth spring 29 urges the gasket 28 to abut against the bottle mouth of the oil bottle assembly 3, improving the sealing performance of the assembly.

[0069] Reference Figure 7 , the oil bottle assembly 3 includes a bottle body 31 and a collar 32. The collar 32 is sleeved on the top of the bottle body 31. A first card slot 321 matching with the steel ball 251 is provided on the outer side of the collar 32.

[0070] Reference Figure 5 And Figure 10 , the first housing 1 further includes a second cavity 12, and an air pump 4 is provided in the second cavity 12;

[0071] A partition assembly 5 is provided between the first cavity 11 and the second cavity 12. The partition assembly 5 is provided with a third air passage 50, and the air pump 4 conveys air flow to the first cavity 11 through the third air passage 50;

[0072] The air pump 4 delivers gas to the first cavity 11, causing a certain air pressure to be formed in the first cavity 11. The gas enters the first ventilation passage 211 and then enters the atomizing head 23. The atomizing head 23 atomizes the oil liquid and the like under the action of the air flow. The atomized gas enters the inner cavity 213, then enters the second ventilation passage 212, and finally flows out to the outside from the mist outlet 221;

[0073] The third ventilation passage 50 is provided with a backflow prevention mechanism 6, which can prevent gas from flowing back and prevent the oil liquid or the atomized oil liquid from flowing towards the air pump 4 and corroding the air pump 4, playing a role in protecting the air pump 4.

[0074] The backflow prevention mechanism 6 includes a ball 61 and a floating cavity 62. A floating cavity 62 is provided above the air inlet 501 or the air outlet 502 of the third ventilation passage 50, and the ball 61 is arranged in the floating cavity 62. For example, refer to Figure 8 , a floating cavity 62 communicating with it is provided above the air inlet 501. When the air pump 4 delivers air flow to the first cavity 11, the air flow blows the ball 61 to move upward, thereby opening the air inlet 501, and the gas can flow towards the first cavity 11. When the air pump 4 stops working, the ball 61 blocks the air inlet 501 under the action of its own gravity, and the gas cannot flow back.

[0075] Refer to Figure 11 , the separation assembly 5 includes a first member 51, a second member 52 and a third member 53;

[0076] The first member 51 is provided with an air outlet 502 and a first flange 511. The air outlet 502 is located in the middle, and the first flange 511 is arranged around the air outlet 502 and extends downward;

[0077] The second member 52 is provided with a second flange 521 and a third flange 522. The second flange 521 extends upward, and the third flange 522 extends downward;

[0078] The third member 53 is provided with an air inlet 501 and a fourth flange 531. The air inlet 501 is located in the middle, and the fourth flange 531 is arranged around the air inlet (501) and extends upward;

[0079] Among them, the first flange 511, the second flange 521, the third flange 522 and the fourth flange 531 are all annular. The first flange 511 and the second flange 521 are arranged in an interlaced manner, and the third flange 522 and the fourth flange 531 are arranged in an interlaced manner, thereby forming the third ventilation passage 50.

[0080] Thus, the first flange 511, the second flange 521, the third flange 522 and the fourth flange 531 cooperate with each other to form a circuitous or labyrinthine third ventilation passage 50; the number of the first flange 511, the second flange 521, the third flange 522 and the fourth flange 531 can be set to one or more, and can be appropriately set according to needs. In this way, the gas in the first cavity 11 needs to pass through a circuitous path (bypassing multiple flanges) to flow to the second cavity 12, increasing the length of the third ventilation passage 50, increasing the resistance of gas reflux, and preventing the oil fluid from flowing to the second cavity 12.

[0081] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model.
