[0044] Example 1

[0045] Please refer to Figure 4 , Figure 7 This utility model provides a diffuser, which has a shell 3, the shell 3 is hollow, a base 31 is provided at the bottom of the shell 3, and an opening is provided at the upper part (i.e. the mounting end) of the shell 3, which communicates with its interior.

[0046] Please refer to Figure 5 , Figure 6 The outer shell 3 has an inner liner 4, which has a first receiving cavity 41, a second receiving cavity 42, and a third receiving cavity 43 arranged sequentially from top to bottom. The first receiving cavity 41 and the second receiving cavity 42 are connected by a through hole. An air pump 421 is placed in the second receiving cavity 42, and the output end of the air pump 421 is located in the through hole. The third receiving cavity 43 is provided with a charging interface and an operating element, and a part of the charging interface and the operating element extends out of the outer shell 3.

[0047] It should be noted that the third receiving cavity 43 is also equipped with components such as a controller and a battery pack.

[0048] refer to Figure 5 The outer shell 3 also includes an integral inner liner, which is open at the top and closed at the bottom. The lower end of the integral inner liner is located in the first receiving cavity 41. The integral inner liner has a connecting hole 131, which connects the inside and outside of the integral inner liner. The number of connecting holes 131 can be one or more. The space between the bottom surface of the integral inner liner and the bottom surface of the first receiving cavity 41, and the space between the outer wall of the integral inner liner and the inner wall of the first receiving cavity 41, form a first air chamber 5 that is interconnected. The upper end of the first air chamber 5 is sealed by a sealing element (the sealing element is located between the outer wall of the annular liner 1 and the inner wall of the first receiving cavity 41).

[0049] It should be noted that in this solution, the number of connection holes 131 is one.

[0050] It should be noted that the sealing element uses a sealing ring.

[0051] refer to Figure 5 A mounting bracket 6 is detachably connected to the opening at the top of the integrated inner liner. An essential oil bottle 7 is detachably connected to the bottom of the mounting bracket 6, and the essential oil bottle 7 is located within the integrated inner liner. The space between the bottom of the essential oil bottle 7 and the inner bottom surface of the integrated inner liner, and the space between the outer wall of the essential oil bottle 7 and the inner wall of the integrated inner liner, form a second air chamber 8 that is interconnected. The top of the second air chamber 8 is sealed by the mounting bracket 6. The first air chamber 5 and the second air chamber 8 are connected through a connecting hole 131 on the inner liner.

[0052] It should be noted that the top of the mounting bracket 6 is equipped with an atomizing head, and the mounting bracket 6 also includes an atomizing core, an oil suction pipe, an air inlet, and an atomizing channel communicating with the atomizing head. This utility model does not involve improvements to the atomizing head and the oil suction pipe; the atomizing head and the oil suction pipe can refer to existing technologies. For example, the oil suction pipe can refer to utility model patent CN220195287U, entitled "A Novel Flow Guiding Device and a Container Containing the Same." The atomizing head can refer to utility model patent CN220424250U, entitled "An Anti-Leakage Oil Diffuser."

[0053] It should be noted that appropriate sealing structures must be provided between the essential oil bottle 7 and the mounting bracket 6, between the mounting bracket 6 and the atomizing head, and between the mounting bracket 6 and the inner liner to prevent leakage.

[0054] During operation, the air pump 421 starts, and gas enters the first air chamber 5. Further, the gas in the first air chamber 5 enters the second air chamber 8 through the connecting hole 131. Further, the gas in the second air chamber 8 supplies air to the atomizing core through the air inlet on the mounting bracket 6, and then atomizes the essential oil through the atomizing core and oil suction tube, and then inputs it into the environment from the top atomizing head.

[0055] Using the solution in this embodiment, there is no need to pass through pipes during the gas delivery process, thus eliminating the problem of gas leakage due to pipe rupture (which can cause abnormal noise and affect the atomization effect).

[0056] Example 2

[0057] The integrated inner liner in Example 1 is described in detail.

[0058] Please refer to Figure 1 , Figure 2 , Figure 3 The integrated inner liner has an annular liner 1 and a bottom plate 2. The annular liner 1 has openings at both ends, and the bottom plate 2 is sealed to the opening at the bottom of the annular liner 1.

[0059] As a preferred option, both the annular inner tube 1 and the base plate 2 are made of metal. Essential oils are corrosive to plastic materials; if the annular inner tube 1 and base plate 2 are made of plastic, they will deform slightly upon contact with the essential oil, affecting airtightness and potentially causing a lack of mist. In contrast, the annular inner tube 1 and base plate 2 made of metal will not deform.

[0060] As a further preferred option, refer to Figure 3 The annular bladder 1 and the base plate 2 are integrally formed to avoid leakage.

[0061] It should be noted that the annular bladder 1 and the base plate 2 can also be connected and sealed by welding, but welding may cause leakage due to welding quality, airflow impact, etc.

[0062] It should be noted that the sealing connection between the annular bladder 1 and the base plate 2 can also be achieved by detachment, but the detachable connection method may result in leakage.

[0063] As a preferred embodiment, the inner diameter of the annular bladder 1 is 3mm to 300mm.

[0064] As a preferred embodiment, there should be an appropriate distance between the connecting hole 131 and the base plate 2. This distance is limited in the following way: the ratio of the distance between the connecting hole 131 and the base plate 2 to the overall height of the annular inner liner 1 is 1:10 to 1:1.5, in order to avoid leakage of essential oil from the integrated inner liner.

[0065] Example 3

[0066] The integrated inner liner will be further described based on Example 2.

[0067] refer to Figure 7 , Figure 8 After the integrated inner liner is assembled, in order to ensure the coaxiality of the outer shell 3 and the annular inner liner 1, the following solution is adopted: a horizontally extending flange 111 is provided at the upper end of the outer wall of the annular inner liner 1, and the flange 111 is an annular structure; a positioning hole 32 is provided on the upper end face of the outer shell 3, and the positioning hole 32 is coaxial with the cavity inside the outer shell 3. After the integrated inner liner and the outer shell 3 are assembled, the flange 111 fits into the positioning hole 32. By the outer wall of the flange 111 fitting into the inner wall of the positioning hole 32, the relative position of the annular inner liner 1 and the outer shell 3 is limited in the radial direction, thus ensuring the coaxiality of the two.

[0068] It should be noted that other methods can also be used to define the relative position of the outer shell 3 and the annular bladder 1 in the radial direction. For example, multiple pairs of interlocking blocks and slots (not shown in the figure) can be provided between the annular bladder 1 and the outer shell 3. The multiple pairs of blocks and slots are evenly distributed in the circumferential direction.

[0069] It should be noted that by using the folded edge 111 and the positioning hole 32, in addition to limiting the relative position of the outer shell 3 and the annular liner 1 in the radial direction, the bottom surface of the folded edge 111 can also limit the depth of the one-piece inner liner inserted into the outer shell 3 by fitting the bottom surface of the positioning hole 32, thereby limiting the relative position of the one-piece inner liner and the outer shell 3 in the axial direction.

[0070] For the preferred option, please refer to Figure 8 Since the folded edge 111 needs to be embedded in the positioning hole 32, there will inevitably be a gap between the outer wall of the folded edge 111 and the positioning hole 32, affecting the positioning accuracy. To further improve this problem, the following improvements are made:

[0071] The lower end face of the folded edge 111 and the bottom face of the positioning hole 32 are set as conical surfaces. When the folded edge 111 is fitted into the positioning hole 32, the integrated inner liner is slightly adjusted in position under the guidance of the conical surface due to the influence of gravity, thereby improving the coaxiality of the two.

[0072] Example 4

[0073] The integrated inner liner is further described based on the above embodiments.

[0074] refer to Figure 1 , Figure 2 , Figure 3 The outer surface of the annular bladder 1 is stepped, and its outer diameter decreases from top to bottom. From top to bottom, it consists of the first section 11, the second section 12 and the third section 13. The connecting hole 131 is provided on the third section 13, and the bottom plate 2 is sealed and connected to the bottom of the third section 13.

[0075] As a preferred option, refer to Figure 1 , Figure 2 A groove 132 is provided in the third section 13. One end of the groove 132 is connected to the connecting hole 131, and the other end of the groove 132 extends downward out of the bottom plate 2. By providing the groove 132, when the connecting hole 131 is in contact with the inner wall of the first receiving cavity 41, the gas in the first air chamber 5 can be guided into the connecting hole 131 through the groove 132, thus avoiding blockage of the connecting hole 131.

[0076] As a further preferred option, refer to Figure 1 The groove 132 can be set vertically; see reference. Figure 2 It can also be installed on the outer wall of the third section 13 by spiral winding. Figure 3 ).

[0077] As a preferred option, refer to Figure 2 A mounting groove 133 is provided at the top of the third section 13 for mounting the sealing ring. The position of the sealing ring is defined by the stepped surface between the third section 13 and the second section 12.

[0078] As a preferred option, refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 In order to ensure the coaxiality of the first receiving cavity 41 and the annular liner 1, a slot 112 is provided on the first section 11, and multiple locking teeth 44 are evenly arranged circumferentially on the top of the inner liner 4. After the integrated inner liner and the inner liner 4 are assembled, the multiple locking teeth 44 engage with the slot 112, which limits the relative position of the inner liner and the inner liner 4 in the radial direction, ensuring the coaxiality of the two.

[0079] It should be noted that the reference Figure 6 The locking tooth 44 includes a connecting part 441 and an engaging part 442. The connecting part 441 connects the engaging part 442 and the inner liner 4. The engaging part 442 protrudes into the inner liner 4. To facilitate the insertion of the engaging part 442 into the slot 112, a guide slope is provided on the inner wall of the top surface of the engaging part 442. During assembly, when the engaging part 442 contacts the outer edge of the bottom plate 2 of the integrated inner liner, it can elastically deform outward by the guidance of the guide slope until the engaging part 442 enters the slot 112, after which the engaging part 442 returns to its original shape.

[0080] It should be noted that by using the slot 112 in conjunction with multiple locking teeth 44, the lower end face of the engaging part 442 can be fitted with the lower end face of the slot 112 to restrict the separation of the integrated inner liner from the first receiving cavity 41, thereby restricting the relative position of the integrated inner liner and the inner liner 4 in the axial direction. By using the folded edge 111 and positioning hole 32 of the above embodiment 3, the integrated inner liner can be fixed relative to the outer shell 3 in the axial direction.

[0081] It should be noted that the reference Figure 5 In order to ensure the coaxiality of the first receiving cavity 41 and the annular bladder 1, after the integrated inner bladder and inner liner 4 are assembled, a part of the second section 12 is inserted into the first receiving cavity 41. Since the outer diameter of the second section 12 is larger than the outer diameter of the third section 13, the gap between the second section 12 and the first receiving cavity 41 is smaller, which can limit the relative position of the annular bladder 1 and the first receiving cavity 41 in the radial direction.

[0082] It should be noted that setting the first section 11, the second section 12 and the third section 13 in a sequentially decreasing manner can ensure that the outer wall of the annular bladder 1 is coaxial with the inner wall of the first receiving cavity 41. In addition, it can also ensure a large and uniform gap between the third section 13 forming the first air chamber 5 and the first receiving cavity 41, ensuring smooth gas flow.

[0083] As a further preferred option, refer to Figure 2 A guide surface 14 is provided at the shoulder of the second section 12 and the first section 11. The guide surface 14 can be machined by chamfering or rounding. By providing the guide surface 14, when assembling the integrated inner liner and inner lining 4, the guide surface 14 guides the retaining teeth 44 from the second section 12 into the first section 11, avoiding the shoulders of the first section 11 and the second section 12 from pressing against the retaining teeth 44 and hindering the assembly.

[0084] The combined effect of Examples 3 and 4 ensures the shape stability of the first air chamber 5, and the outer wall of the integrated inner liner and the inner wall of the first receiving cavity 41 have a relatively uniform gap in the circumferential direction, ensuring the stability of airflow when passing through the first air chamber 5.

[0085] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
