[0045] Example 1

[0046] Please refer to Figure 1 , Figure 2 This utility model provides an aroma diffuser, which includes an outer shell 1. The outer shell 1 has an annular sidewall 11 extending vertically, and the top of the annular sidewall 11 extends horizontally inward to form an annular upper surface 12. The aroma diffuser also includes a bottom cover 2, which has a conical sidewall 21. The bottom surface of the conical sidewall 21 extends horizontally inward to form a lower surface 22. The bottom cover 2 is connected to the lower end of the outer shell 1. An inner liner 7 is provided inside the outer shell 1, and an inner liner 3 is provided inside the inner liner 7. An atomizing core 4 is connected to the inner liner 3. An atomizing head 5 is connected to the top of the atomizing core 4, and an essential oil bottle 6 is connected to the bottom of the atomizing core 4. The essential oil bottle 6 is located in the inner liner 3.

[0047] The essential oil bottle 6 is a hollow structure with an open top and a sealed bottom. Essential oil bottle 6 is used to store essential oils.

[0048] As a preferred option, the essential oil bottle 6 is made of metal.

[0049] The essential oil bottle 6 is made of metal, which can prevent the essential oil from corroding the bottle. If the essential oil bottle 6 is corroded, it will deform, affecting the misting effect and sealing.

[0050] As a preferred option, both the outer shell 1 and the bottom cover 2 are made of metal materials. Specifically, stainless steel can be used. If cost is not a concern, copper, aluminum, and various alloy metals can also be used. The use of metal materials can effectively resist the corrosion and dissolution of essential oils, allowing the diffuser shell to maintain its appearance for a long time.

[0051] Example 2

[0052] refer to Figure 2 , Figure 3 The atomizing core 4 in Example 1 will be described in detail.

[0053] The diffuser also includes an atomizing core 4, with an atomizing head 5 mounted on its top. The atomizing core 4 has a stepped shape from top to bottom, comprising a first section 41, a second section 42, and a third section 43 arranged sequentially. The first section 41, the second section 42, and the third section 43 are coaxial, and a retaining ring 44 is provided between the first section 41 and the second section 42. The top of the first section 41 has a first mounting groove 411 for mounting a sealing ring, which seals the gap between the atomizing head 5 and the atomizing core 4. The outer wall of the first section 41 has a first connecting structure, and the bottom of the atomizing head 5 has a mounting hole with a second connecting structure inside. The first connecting structure and the second connecting structure cooperate to connect the atomizing head 5 to the atomizing core 4. The second section 42 includes a second mounting groove 421 located below the retaining ring 44. The second mounting groove 421 is used to install a sealing ring, which seals the gap between the atomizing core 4 and the inner liner 3. The outer wall of the second section 42 is provided with a third connecting structure, and the opening of the inner liner 3 is provided with a fourth connecting structure. The third and fourth connecting structures cooperate to connect and fix the atomizing core 4 and the inner liner 3. The diameter of the third section 43 is smaller than that of the second section 42. The top of the third section 43 is provided with a third mounting groove 431, which is used to install a sealing ring, which seals the gap between the atomizing core 4 and the essential oil bottle 6. The outer wall of the third section 43 is provided with a fifth connecting structure, and the opening of the essential oil bottle 6 is provided with a sixth connecting structure. The fifth and sixth connecting structures cooperate to connect and fix the atomizing core 4 and the essential oil bottle 6.

[0054] It should be noted that the first, second, third, fourth, fifth, and sixth connecting structures are preferably threaded.

[0055] The atomizer core 4 is made of metal. First, this reduces or prevents the corrosion of the first, third, and fifth connecting structures on the surface of the atomizer core 4 by essential oils (which use plastic threads, which can strip under the corrosion of essential oils, leading to loose connections; and the plastic itself can age, resulting in loss of mechanical properties and connection failure). Second, the plastic atomizer core 4 can deform under the action of essential oils, leading to sealing failure. Third, the plastic atomizer core 4 can form plastic particles on its surface under the action of essential oils, which may cause airflow blockage and air blockage.

[0056] Example 3

[0057] Please refer to Figure 2 , Figure 3 , Figure 8 The inner liner 3 in Example 1 will be described in detail.

[0058] The inner liner 3 has a hollow structure with an open top and a closed bottom. At least one connection hole 31 is provided on the outer side wall of the inner liner 3. The bottom-closed inner liner 3 can store essential oils and prevent them from seeping downwards and corroding components such as the air pump 721 and plastic parts below.

[0059] As a preferred option, the inner liner 3 is made of metal. Essential oils are corrosive to plastic materials; if the inner liner 3 is made of plastic, it will slightly deform upon contact with the essential oil, affecting airtightness and even causing the liner to fail to fog up. Using a metal inner liner 3 prevents these problems from occurring.

[0060] As a preferred option, the inner liner 3 is manufactured using a one-piece molding method.

[0061] It should be noted that connecting the inner liner 3 to the sealing end using welding or detachable methods poses a risk of leakage.

[0062] As a preferred option, the ratio of the distance between the connecting hole 31 and the sealing end of the inner liner 3 to the overall height of the inner liner 3 is 1:10 to 1:1.5, to prevent the essential oil in the inner liner 3 from leaking out of the connecting hole 31.

[0063] As a preferred embodiment, a groove 33 is provided on the outer wall of the inner liner 3. One end of the groove 33 is connected to the connecting hole 31, and the other end of the groove 33 extends downward to the sealing end of the inner liner 3. By providing the groove 33, when the connecting hole 31 is blocked by the inner wall of the first tube 71, the gas in the first air chamber 8 can be guided into the connecting hole 31 through the groove 33, thus avoiding blockage of the connecting hole 31.

[0064] As a further preferred option, the groove 33 can be set in a vertical direction; the groove 33 can also be set on the outer side wall of the inner liner 3 in a spiral winding manner.

[0065] As a preferred embodiment, a fourth mounting groove 34 is provided on the outer wall of the inner liner 3. The fourth mounting groove 34 is used to install a sealing ring, which can seal the first air chamber 8.

[0066] As a preferred option, refer to Figure 2 , Figure 6 , Figure 8 After the inner liner 3 is assembled, a first positioning structure is set up to ensure the coaxiality of the outer shell and the inner liner 3. The first positioning structure adopts the following scheme: a horizontally extending flange 32 is provided at the upper end of the outer wall of the inner liner 3, and the flange 32 is a ring structure; a stepped hole 121 is provided on the upper surface 12, with the larger hole of the stepped hole 121 located on the upper side and the smaller hole of the stepped hole 121 located on the lower side. The side wall of the inner liner 3 can pass through the smaller hole of the stepped hole 121, while the flange 32 is restricted from passing through the larger hole of the stepped hole 121. After the inner liner 3 and the outer shell 1 are assembled, the outer side wall of the inner liner 3 mates with the smaller hole of the stepped hole 121, and the flange 32 mates with the larger hole of the stepped hole 121, which limits the relative position of the inner liner 3 and the outer shell 1 in the radial direction, ensuring the coaxiality of the two.

[0067] It should be noted that the engagement between the folded edge 32 and the stepped surface of the stepped hole 121 can limit the depth to which the inner liner 3 is inserted into the outer shell 1.

[0068] As a preferred embodiment, in order to ensure the coaxiality of the first tube body 71 and the inner liner 3, a second positioning structure is provided. The second positioning structure adopts the following scheme: a snap ring 35 protruding outward is provided on the outer wall of the inner liner 3, and multiple snap teeth 73 are evenly provided on the top of the first tube body 71 along the circumferential direction. After the inner liner 3 and the inner liner 7 are assembled, the multiple snap teeth 73 engage with the snap ring 35, which limits the relative position of the inner liner 3 and the inner liner 7 in the radial direction, thus ensuring the coaxiality of the two.

[0069] It should be noted that the locking tooth 73 includes a connecting part 732 and an engaging part 731. The connecting part 732 is used to connect the engaging part 731 and the inner liner 7. The engaging part 731 protrudes into the inner liner 7. To facilitate the connection between the engaging part 731 and the engaging ring 35, guide slopes are provided on the inner wall of the top surface of the engaging part 731 and on the engaging ring 35. During assembly, when the engaging part 731 contacts the engaging ring 35, it can elastically deform outward under the guidance of the guide slopes until the bottom surface of the engaging part 731 fits against the upper end surface of the engaging ring 35, after which the engaging part 731 returns to its original shape.

[0070] It should be noted that by using a snap ring 35 in conjunction with multiple snap teeth 73, the lower end face of the snap-fit ​​part 731 can be fitted with the upper end face of the snap ring 35 to restrict the separation of the inner liner 3 from the first tube body 71, thereby restricting the relative position of the inner liner 3 and the inner lining 7 in the axial direction. Through the cooperation of the first positioning structure and the second positioning structure, the integrated inner liner 3 can be fixed relative to the outer shell in the axial direction.

[0071] It should be noted that the combined effect of the first positioning structure and the second positioning structure can ensure the shape stability of the first air chamber 8, and the outer wall of the inner liner 3 and the inner wall of the first air chamber 8 have a relatively uniform gap in the circumferential direction, ensuring the stability of airflow through the first air chamber 8.

[0072] Example 4

[0073] The inner liner 7 in Embodiment 1 is described in detail. The inner liner 7 includes a central annular body 74. A first tube 71 and a second tube 72 are respectively provided above and below the annular body 74. The first tube 71 is a hollow structure with an open upper end and is used to install the inner liner 3. The second tube 72 is a hollow structure with an open lower end and is used to install the air pump 721. An air guide hole is provided between the first tube 71 and the second tube 72. The outer diameters of the first tube 71 and the second tube 72 are both smaller than the annular body 74. After the inner liner 7 is installed into the outer shell 1, the annular body 74 fits against the annular sidewall 11 of the outer shell 1 to ensure the coaxiality of the first tube 71 and the outer shell 1.

[0074] As a preferred embodiment, a slot 111 is provided on the inner wall of the annular sidewall 11, and the slot 111 extends downward out of the annular sidewall 11. A block 741 is provided on the outer wall of the annular body 74. In the assembled state, the block 741 is engaged with the slot 111. First, it can limit the relative position of the inner liner 7 and the outer shell 1 in the circumferential direction; second, it can limit the depth of the inner liner 7 inserted into the annular sidewall 11 from bottom to top.

[0075] Multiple connecting posts extend downward from the side wall of the second tube 72. Fasteners pass through the lower surface 22 and are threadedly connected to the connecting posts to further secure the inner liner 7.

[0076] It should be noted that an annular gasket 113 is also provided between the outer shell 1 and the bottom cover 2. The annular gasket 113 is used to seal the gap between the outer shell 1 and the bottom cover 2. A limiting hole 112 coaxial with the annular sidewall 11 is provided at the lower end of the annular sidewall 11. The annular gasket 113 is inserted into the limiting hole 112 from bottom to top and fits against the top surface of the limiting hole 112. The upper end of the conical sidewall 21 rests against the annular gasket 113. The bottom cover 2 and the inner liner 7 are locked together by fasteners.

[0077] Example 5

[0078] The working principle of this utility model will be explained in detail.

[0079] The inner wall of the first tube 71, the outer wall of the inner liner 3, the lower end face of the inner liner 3, the inner bottom surface of the first tube 71, and the sealing ring disposed between the first tube 71 and the inner liner 3 form a first air cavity 8. The outer wall of the essential oil bottle 6, the inner wall of the inner liner 3, and the sealing ring disposed on the second mounting groove 421 form a second air cavity 9.

[0080] During operation, the air pump 721 starts, and gas enters the first air chamber 8. Further, the gas in the first air chamber 8 enters the second air chamber 9 through the connecting hole 31. Further still, the gas in the second air chamber 9 supplies air to the atomizing core 4 through the air inlet on the atomizing core 4. Then, through the atomizing core 4 and other components such as the oil suction tube, the essential oil is atomized and introduced into the environment from the top atomizing head 5.

[0081] It should be noted that this utility model does not involve any improvement to the internal structure of the atomizing core 4, nor does it involve any improvement to the oil suction tube. The technology for realizing the atomizing core 4 and the oil suction tube can refer to the existing technology.
