Detailed implementation mode

[0053] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0054] Refer to Figures 1 to 7 , the aromatherapy machine, comprising an outer shell 1, an atomization component 2 and an oil bottle assembly 3;

[0055] The outer shell 1 has a first cavity 11, and the first cavity 11 can accommodate the oil bottle assembly 3;

[0056] Refer to Figure 2, the atomization component 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-angle 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 to the air outlet 221 and finally flows to the outside.

[0057] Reference Figure 2 , the atomization component 2 is provided with a first clamping mechanism 25 and a second clamping mechanism 26;

[0058] The first clamping mechanism 25 is clamped with the top of the oil bottle assembly 3;

[0059] The second clamping mechanism 26 is clamped with the side wall of the housing 1 or the first cavity 11.

[0060] Assembly steps: First, the oil bottle assembly 3 is connected to the atomization component 2 through the first clamping mechanism 25, so that the oil bottle assembly 3 and the atomization component 2 form a whole. Then, the oil bottle assembly 3 and the atomization component 2 are put into the first cavity 11 as a whole, and the atomization component 2 is connected to the side wall of the housing 1 or the first cavity 11 through the second clamping mechanism 26. Thus, through the clamping mechanism for connection, convenient and rapid assembly is realized.

[0061] Reference Figure 5 , the first clamping mechanism 25 includes a steel ball 251, a sliding sleeve 252 and a first spring 253;

[0062] The atomization component 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;

[0063] A radial hole 2141 capable of accommodating the steel ball 251 is provided on the first cavity wall 214 of the inner cavity 213;

[0064] The sliding sleeve 252 is sleeved on the outside of the first cavity wall 214 in a relatively movable manner;

[0065] The lower end of the sliding sleeve 252 is provided with an inclined surface part 2521 arranged obliquely outwards;

[0066] 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.

[0067] 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.

[0068] 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, which is convenient and fast for both assembly and disassembly.

[0069] Reference Figure 6 , 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.

[0070] 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.

[0071] At the lower end of the vertical arm 2612, there is a buckle portion 2612a.

[0072] On the side wall of the outer shell 1 or the first cavity 11, there is a second card slot 110 that cooperates with the buckle portion 2612a.

[0073] 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.

[0074] 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.

[0075] Reference Figure 6 And Figure 7 , at the connection between the horizontal arm 2611 and the vertical arm 2612, there is a rotating shaft portion 2613.

[0076] The bracket 262 is provided with a shaft hole portion 2621 that cooperates with the rotating shaft portion 2613, realizing the swinging of the horizontal arm 2611 and the vertical arm 2612 with the rotating shaft portion 2613 as the axis or pivot point.

[0077] The side wall of the bracket 262 is provided with a notch portion 2623 capable of accommodating the vertical arm 2612, providing space for the connection between the buckle portion 2612a and the second card slot 110;

[0078] The top wall of the bracket 262 is provided with a recessed portion 2622 capable of accommodating 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;

[0079] Wherein, a plurality of horizontal arms 2611 and vertical arms 2612 can be correspondingly arranged and arranged in a circumferential array, so that the clamping member 261 is in a ring-shaped or sleeve-shaped structure; similarly, the bracket 262 is correspondingly provided with a plurality of shaft hole portions 2621, recessed portions 2622 and notch portions 2623, so that the bracket 262 is in a ring-shaped or sleeve-shaped structure.

[0080] Reference Figure 6 , 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.

[0081] Reference Figure 6 , 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 looseness can be reduced.

[0082] Reference Figure 6 And Figure 7 , the second clamping mechanism 26 further includes a panel 260, the panel 260 is arranged above the horizontal arm 2611, and a convex portion 2611a is arranged at one end of the horizontal arm 2611 away from the vertical arm 2612.

[0083] Thus, by pushing the panel 260 downward, the horizontal arm 2611 can be pushed to swing downward, and then the vertical arm 2612 can be driven to swing outward, so that the buckle portion 2612a is disengaged 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 housing 1, realizing convenient disassembly.

[0084] Among them, the provision of the convex portion 2611a facilitates the transfer 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.

[0085] Reference Figure 5 , the atomization assembly 2 further includes a pressure ring 27, a gasket 28 and a fourth spring 29;

[0086] 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.

[0087] Reference Figure 5 , 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 that cooperates with the steel ball 251 is provided on the outer side of the collar 32.

[0088] Reference Figure 8 And Figure 9 , the housing 1 further includes a second cavity 12, and an air pump 4 is provided in the second cavity 12;

[0089] 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 ventilation passage 50. The air pump 4 conveys air flow to the first cavity 11 through the third ventilation passage 50;

[0090] The air pump 4 conveys gas to the first cavity 11, prompting 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, etc. 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 to the outside from the mist outlet 221;

[0091] The third ventilation passage 50 is provided with a backflow prevention mechanism 6, which can prevent gas from flowing back, prevent the oil liquid or 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.

[0092] 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. The ball 61 is arranged in the floating cavity 62. For example, reference Figure 8 , a floating cavity 62 communicating with it is provided above the air inlet 501. When the air pump 4 conveys air flow to the first cavity 11, the air flow blows the ball 61 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.

[0093] Reference Figure 8 AndFigure 9 , the first embodiment of the separation component 5, the separation component 5 includes a first member 51, a second member 52 and a third member 53;

[0094] 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, the first flange 511 is arranged around the air outlet 502, and the first flange 511 extends downward;

[0095] 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;

[0096] 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, the fourth flange 531 is arranged around the air inlet (501), and the fourth flange 531 extends upward;

[0097] Wherein, 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, so as to form a third ventilation channel 50.

[0098] 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 tortuous or labyrinthine third ventilation channel 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 tortuous path (it needs to bypass multiple flanges) to flow to the second cavity 12, increasing the length of the third ventilation channel 50, increasing the resistance of gas reflux, and preventing the oil from flowing to the second cavity 12.

[0099] Reference Figure 10 And Figure 11 , the second embodiment of the separation component 5, the separation component 5 includes a first member 51 and a third member 53;

[0100] The edge part of the first member 51 is provided with the air outlet 502;

[0101] The third component 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. An opening 532 is provided at the top of the fourth flange 531. Thus, the structure of the fourth flange 531 forms a circuitous or labyrinthine third ventilation passage 50. Among them, there may be multiple fourth flanges 531, and each fourth flange 531 is provided with a corresponding opening 532, so as to form multiple sequentially connected ventilation passages, increasing the length of the third ventilation passage 50, and the air flow directions of adjacent ventilation passages are opposite. After the gas passes through multiple ventilation passages in sequence, it flows from the air inlet 501 to the first cavity 11. Similarly, the gas in the first cavity 11 needs to pass through a circuitous path to flow to the second cavity 12, increasing the resistance of gas reflux and preventing the oil from flowing to the second cavity 12.

[0102] It can be seen that compared with the first embodiment of the separation component 5, the second embodiment reduces the setting of the second component 52 and has a simpler structure.

[0103] Reference Figure 12 , the aromatherapy machine further includes a bottom case 7, a stand 8 and a circuit board. The bottom case 7 is arranged below the outer shell 1. The upper end of the bottom case 7 can be connected to the outer shell 1 by threads, and the lower end of the bottom case 7 can be connected to the base by threads.

[0104] The circuit board is assembled on the stand 8, and the stand 8 is assembled inside the bottom case 7.

[0105] The setting of the stand 8 facilitates the assembly of electronic components such as the circuit board. For example, multiple electronic components such as the first circuit board 91 and the second circuit board 92 can be first assembled on the stand 8 through structures such as screws or buckles, and then, as a whole with the stand 8, assembled inside the bottom case 7. The stand 8 can be fixed inside the bottom case 7 through structures such as screws or buckles, or the bottom of the stand 8 can be fixed to the base through structures such as screws or buckles, thus forming a modular assembly, which is more convenient for assembly and disassembly.

[0106] The above discloses 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 deformations and improvements can still be made, and these all belong to the protection scope of the utility model.
