Technical personnel in the field can understand their specific meanings in this application according to the specific circumstances.

[0032] like Figures 1 to 5As shown, the aromatherapy device of this embodiment includes a bottle body 1, a cover body 2 and a pressure relief channel 22. A storage cavity 11 is provided in the bottle body 1, and the storage cavity 11 is provided with an opening 111. The cover body 2 is covered on the opening 111. The pressure relief channel 22 is provided near one end of the cover body 2, and is connected to the storage cavity 11 and the outside of the cover body 2 respectively.

[0033] Among them, the aromatherapy liquid (also known as aromatherapy essential oil or essence) is stored in the storage cavity 11 of the bottle body 1 and diffuses to the outside through the opening and / or the pressure relief channel 22 on the bottle body 1, thereby diffusing the fragrance. The aromatherapy can be diffused through a diffuser stick, or the bottle body 1 can be directly heated to heat the aromatherapy liquid and diffuse it quickly.

[0034] The aromatherapy device of this embodiment stores aromatherapy liquid in a storage chamber 11. The storage chamber 11 is provided with an opening 111 for replacing the aromatherapy liquid. The cover 2 covers the opening 111 to prevent the aromatherapy liquid from leaking. After the cover 2 covers the opening 111, the storage chamber 11 is in a relatively closed state. The storage chamber 11 is connected to the outside of the cover 2 through a pressure relief channel 22. Under high temperature conditions, part of the aromatherapy liquid in the bottle 1 expands due to the heat, squeezing out the air. The air can be discharged through the pressure relief channel 22, thereby balancing the air pressure inside the bottle 1 and the outside, preventing the aromatherapy liquid from overflowing, and ensuring a good user experience.

[0035] In a possible embodiment, the pressure relief channel 22 includes a conducting hole 221 provided on the cover body 2. The conducting hole 221 is arranged opposite to the opening 111. The conducting hole 221 connects the storage cavity 11 in the bottle body 1 with the outside of the cover body 2, and the air pressure difference between the storage cavity 11 and the outside is balanced through the conducting hole 221.

[0036] In one possible embodiment, the diameter of the through hole 221 ranges from 0.5 mm to 2 mm. A through hole 221 larger than 0.5 mm facilitates production and prevents damage to equipment during the production process. For example, a too small diameter may cause the through-hole needle to break. It is understood that the smaller the diameter of the through hole 221, the less likely the liquid in the bottle body 1 will overflow from the through hole 221 due to shaking. Therefore, preferably, the diameter of the through hole 221 ranges from 0.5 mm to 2 mm.

[0037] In one possible embodiment, Figures 5 to 7 As shown, the aromatherapy device also includes a liquid conducting rod 3, a through hole 25 is provided on the cover body 2, the liquid conducting rod 3 passes through the through hole 25 and is at least partially provided in the storage cavity 11, and the conducting hole 221 is provided on the outer periphery of the liquid conducting rod 3, that is, the conducting hole 221 is provided outside the through hole 25.

[0038] Specifically, in this embodiment, the aromatherapy liquid in the bottle body 1 is diffused by a diffuser rod. The diffuser rod in this embodiment is, for example, a cotton liquid-conducting rod 3. The side wall of the liquid-conducting rod 3 abuts against the inner wall of the through hole 25. Therefore, the through hole 221 is provided on the periphery of the through hole 25 so that the through hole 221 and the through hole 25 do not affect each other.

[0039] In one possible embodiment, Figures 5 to 7 As shown, the cover body 2 includes a accommodating portion 21 on a side away from the storage chamber 11, and a liquid storage block 31 is sleeved on the end of the liquid-conducting rod 3 away from the storage chamber 11, and the liquid storage block 31 is arranged in the accommodating portion 21; the pressure relief channel 22 also includes a pressure relief through hole 311 connected to the opening 111, and the pressure relief through hole 311 is arranged on the liquid storage block 31 and connected to the outside of the cover body 2.

[0040] The liquid reservoir block 31 is sleeved on the liquid guide rod 3 and the two form an interference fit, so that the aromatherapy liquid absorbed by the liquid guide rod 3 can be diffused into the liquid reservoir block 31. The liquid reservoir block 31 is a cotton liquid reservoir block 31, which is used to increase the diffusion area of ​​the aromatherapy liquid to enhance the aromatherapy effect. The pressure relief through hole 311 on the liquid reservoir block 31 is connected to the conductive hole 221. For example, the pressure relief through hole 311 is arranged opposite to the conductive hole 221, so that the aromatherapy liquid and air in the bottle body 1 can be discharged after passing through the conductive hole 221 and the pressure relief through hole 311.

[0041] In a possible embodiment, the pressure relief channel 22 further includes a channel gap 211 . The channel gap 211 is provided between the liquid storage block 31 and the cover body 2 . The channel gap 211 is communicated with the through hole 221 and the outside of the cover body 2 , respectively.

[0042] Specifically, a lifting column 23 is provided on the side of the cover body 2 facing away from the storage cavity 11, and the liquid storage block 31 abuts the lifting column 23, so that a channel gap 211 is formed between the liquid storage block 31 and the cover body 2. The upper and lower ends of the lifting column 23 are respectively connected to the liquid storage block 31 and the cover body 2 to form the channel gap 211, so that the air and aromatherapy liquid in the bottle body 1 can pass through the conducting hole 221 to reach the channel gap 211, and finally be discharged to the outside of the cover body 2.

[0043] The height of the channel gap 211 is determined by the height of the raising posts 23. Multiple raising posts 23 are provided in the accommodating portion 21 to enhance the strength and stability of the support mechanism. The raising posts 23 cannot restrict the flow of the aromatherapy liquid in the channel gap 211. Therefore, when the raising posts 23 extend from the inner wall of the accommodating portion 21 to the through hole 25, a disconnected portion needs to be provided on the raising posts 23 to avoid restricting the flow of the aromatherapy liquid.

[0044] Furthermore, the height of the raising column 23 is related to the thickness of the liquid reservoir block 31, and the height of the raising column 23 is greater than 0.1 times the thickness of the liquid reservoir block 31. It is understandable that the height of the raising column 23 in the height direction of the bottle body 1 (i.e., the height of the channel gap 211 in the height direction of the bottle body 1) is greater than 0.1 times the thickness of the liquid reservoir block 31 in the height direction of the bottle body 1. Since the liquid reservoir block 31 expands when absorbing liquid, generally the liquid reservoir block 31 expands by 10%. The height of the raising column 23 is greater than 0.1 times the thickness of the liquid reservoir block 31 to prevent the liquid reservoir block 31 from completely filling the channel gap 211 after absorbing the liquid, thereby preventing the gas in the bottle body 1 from being decompressed through the conducting hole 221.

[0045] In one possible embodiment, Figures 5 to 7 As shown, the accommodating portion 21 includes a accommodating tank, a liquid storage block 31 is arranged in the accommodating tank, a lifting column 23 is provided on the bottom wall of the accommodating tank, the liquid storage block 31 is arranged on the lifting column 23, and the bottom of the liquid storage block 31 and / or the side wall of the liquid storage block 31 and the side wall of the accommodating tank form a channel gap 211, and the channel gap 211 is respectively connected to the through hole 221 and the outside of the cover body 2.

[0046] Among them, the bottom of the liquid storage block 31 and the bottom of the receiving tank form a horizontal channel gap 211, and the side wall of the liquid storage block 31 and the side wall of the receiving tank can also form a vertical channel gap 211. The air in the bottle body 1 passes through the conducting hole 221 and is connected to the pressure relief through hole 311 or the channel gap 211. Specifically, when the liquid storage block 31 is arranged above the lifting column 23, the channels for communicating the air in the bottle body 1 with the outside of the cover body 2 include: a first channel communicating with the conductive hole 221, the channel gap 211 in the horizontal plane, and the pressure relief through hole 311; a second channel communicating with the through hole 221 and the channel gap 211 in the horizontal plane; and the conductive hole 221, the channel gap 211 in the horizontal plane, and the channel gap in the vertical direction. The air in the bottle body 1 is connected to the outside through the conductive channel, thereby preventing the aromatherapy liquid in the bottle body 1 from leaking under high temperature conditions. Moreover, when the aromatherapy liquid in the bottle body 1 expands and leaks due to high temperature, the aromatherapy liquid enters the receiving tank from the opening 111 for temporary storage, thereby preventing the aromatherapy liquid from leaking to the outside. After the temperature drops, the aromatherapy liquid can flow from the accommodating portion 21 into the bottle body 1 through the pressure relief channel 22, thereby avoiding waste of the aromatherapy liquid.

[0047] In a possible embodiment, the bottle body 1 is provided with a connecting portion 12 connected to the cover body 2 , the side walls of the connecting portion 12 enclose an opening 111 , and a sealing member 4 is provided between the connecting portion 12 and the cover body 2 .

[0048] Among them, the liquid-guiding rod 3 is inserted into the storage cavity 11 through the opening 111, so that the aromatherapy liquid in the bottle body 1 can be adsorbed and diffused out. In order to stably connect the cover body 2 and the bottle body 1, in this embodiment, the connecting part 12 is a cylinder, and the outer side wall of the connecting part 12 is provided with an external thread to form an external thread column. The cover body 2 is provided with an internal thread hole connected to the external thread column, and the sealing member 4 is provided at the threaded connection between the bottle body 1 and the cover body 2. When the cover body 2 is threadedly connected to the bottle body 1, the sealing member 4 will be squeezed, so that the sealing member 4 has a good sealing effect, thereby preventing the aromatherapy liquid from leaking from the connection between the bottle body 1 and the cover body 2.

[0049] From the periphery of the through hole 25 along the axial direction, a cylindrical body 28 is provided in the internal threaded hole on the cover body 2 and extends into the opening 111 of the bottle body 1. The through hole 25 runs through the entire cylindrical body 28. The external threaded column on the bottle body 1 is provided between the internal threaded hole and the cylindrical body 28. The cylindrical body 28 extends into the bottle body 1, which can prevent the aromatherapy liquid from leaking and make the connection between the bottle body 1 and the cover body 2 more stable.

[0050] In one possible embodiment, Figure 3 and Figure 7 As shown, the aromatherapy device also includes a positioning structure 24, which includes a positioning column 241 provided at the bottom of the receiving tank, a positioning hole 312 connected to the positioning column 241 is provided on the liquid storage block 31, and the positioning column 241 penetrates the positioning hole 312; and / or, the positioning structure 24 includes a positioning block 242 provided on the side wall of the receiving tank, and a positioning groove 313 engaged with the positioning block 242 is provided on the liquid storage block 31, so that the conducting hole 221 is located as far as possible above the pressure relief through hole 311, so that the gas conduction is smoother. The positioning structure 24 is set not only to fix the liquid storage block 31, but also to prevent mistakes.

[0051] Since the liquid reservoir block 31 needs to maintain sufficient area to store the aromatherapy liquid to ensure the diffusion area, the positioning holes 312 on the liquid reservoir block 31 cannot be too many. In this embodiment, there are two positioning holes, the same as the number of the conductive holes 221. Therefore, it is necessary to ensure that the positions of the conductive holes 221 and the pressure relief holes 311 correspond to each other when the liquid reservoir block 31 is installed. In this way, the aromatherapy liquid and air in the bottle body 1 can communicate with the outside through the pressure relief holes 311. In this embodiment, a positioning column 241 and a positioning block 242 are provided at the bottom of the accommodating portion 21 to cooperate with the positioning holes 312 and the positioning groove 313 on the liquid reservoir block 31, respectively, to ensure the accuracy of the position of the liquid reservoir block 31 when installed, and ensure that the positions of the conductive holes 221 and the pressure relief holes 311 correspond to each other.

[0052] In a possible embodiment, the cover body 2 is further provided with a top plate 26 facing the through hole 25 . The top plate 26 is provided above the cover body 2 and spaced apart from the cover body 2 . The top of the liquid-guiding rod 3 is connected to the top plate 26 .

[0053] Among them, a support column supporting the top plate 26 is provided at the bottom of the accommodating groove on the side of the through hole 25, and the top plate 26 is arranged above the support column. Since the liquid-conducting rod 3 is arranged in the through hole 25, the top plate 26 can prevent the liquid-conducting rod 3 from displacing in the axial direction and detaching from the through hole 25.

[0054] In one possible embodiment, Figure 7 As shown, a reflux structure 27 is further provided at the bottom of the accommodating portion 21 . The reflux structure 27 includes a reflux hole that connects the accommodating groove with the through hole 25 .

[0055] When the aromatherapy liquid overflows into the receiving tank at high temperature, after the temperature drops, the aromatherapy liquid can flow directly back into the bottle body 1 through the conducting hole 221. To make the aromatherapy liquid in the receiving portion 21 flow back faster and more thoroughly, this embodiment further provides a reflux structure 27 at the bottom of the receiving tank to assist the aromatherapy liquid in flowing back into the bottle body 1. In this embodiment, the raised columns 23 extend from the inner wall of the receiving tank to the through hole 25. The multiple raised columns 23 arranged at intervals form multiple receiving chambers in the channel gap 211. The raised columns 23 are provided with broken fractures 231 to allow the aromatherapy liquid to flow between the various receiving chambers. The reflux structure 27 specifically includes a first reflux structure 271 and a second reflux structure 272 that connect the receiving portion 21 to the through hole 25 and the outer side of the cylindrical body 28, respectively. The first reflux structure 271 and the second reflux structure 272 are both reflux holes, allowing the aromatherapy liquid to flow to the liquid guide rod 3 through the first reflux structure 271 and flow back into the bottle body 1 through the second reflux structure 272.

[0056] Optionally, at the bottom of the receiving tank, the level of the reflux structure 27 is lower than that of other areas, so that the aromatherapy liquid in the receiving portion 21 flows to the reflux structure under the action of gravity, making the aromatherapy liquid in the receiving tank reflux more thoroughly.

[0057] In one possible embodiment, Figure 1 and Figure 2 As shown, the fan 51 is further included. The fan 51 is arranged above the liquid storage block 31, and the air outlet of the fan 51 is facing the liquid storage block 31. The air blown by the fan 51 directly faces the liquid storage block 31, which can quickly volatilize the aromatherapy liquid on the liquid storage block 31 and accelerate the diffusion of the fragrance. At the same time, the air blown by the fan 51 directly faces the liquid storage block 31. The liquid storage block 31 is provided with a pressure relief through hole 311, which is connected to the receiving tank. If aromatherapy liquid accumulates in the receiving tank, the fan 51 can quickly volatilize the accumulated aromatherapy liquid through the pressure relief through hole 311.

[0058] Among them, the fan 51, the grille plate 52, the circuit board, the control switch, the charging interface and other electronic components together constitute the fragrance permeation device 5. The grille plate 52 is arranged on the cover body 2 to support the fan 51. The circuit board, the control switch and the charging interface and other electronic components are arranged on the grille plate 52 to control the start and stop of the fan 51 and to power the fan 51. The grille plate 52 and the fan 51 are opposite to the liquid storage block 31, and are used to quickly diffuse the aroma liquid in the liquid storage block 31 to accelerate the aromatherapy. The grille plate 52 can play a supporting role, and the aroma can also be diffused through the grille plate 52.

[0059] The aromatherapy device provided in the above embodiments of the present application has at least the following features:

[0060] 1. The conducting hole 221 can discharge the aromatherapy liquid expanded by high temperature in the bottle body 1 into the accommodating portion 21, thereby preventing the aromatherapy liquid from leaking and being wasted.

[0061] 2. A pressure relief hole 311 is provided on the liquid storage block 31. The pressure relief hole 311 can discharge the aroma liquid under special circumstances, further improving safety. At the same time, the pressure relief hole 311 can also serve as a fragrance diffusion path for the aroma liquid in the bottle body 1, thereby enhancing the fragrance diffusion effect.

[0062] 3. A positioning structure 24 is provided in the accommodating portion 21 to cooperate with the positioning hole 312 and the positioning groove 313 of the liquid reservoir 31 to ensure that the positions of the conducting hole 221 and the pressure relief hole 311 correspond to each other. When the liquid reservoir 31 is directly covered on the cover body 1, the aromatherapy liquid can flow into the accommodating portion 21 above the liquid reservoir 31 through the conducting hole 221 and the pressure relief hole 311.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
