Description

Technical Field

[0001] The present application relates to the technical field of hair dryers, and in particular to an essential oil module. Background Art

[0002] As a common item in life, hair dryers can dry hair quickly. However, because the wind from hair dryers is sometimes too hot, it may cause certain damage to the user's hair.

[0003] So the R&D personnel tried to blow the essential oil on the hair by the hair dryer to realize the hair care function of the hair dryer, so there appeared an essential oil module arranged on the hair dryer, which can store volatile essential oils so as to mix the essential oils in the wind flow. But based on the current most of the hair dryer shapes, there are two common ways for the essential oil module to be assembled, one is that the essential oil module is directly installed on the main body of the hair dryer, and the second is that the essential oil module is used in combination with some accessories (such as wind nozzles, etc.), first installed on these accessories, and then the accessories are installed on the main body. After the essential oil module is assembled by the above two methods, the essential oil module is in the outside of the hair dryer as a whole, and it is impossible to preset or be integrated in the whole hair dryer body, which brings inconvenience to the user to a certain extent. In addition, once the essential oil leaks, the essential oil is very easy to adhere to the outer surface of the hair dryer, which brings inconvenience to the user's use and affects the normal use of the user. Utility Model Content

[0004] Based on this, it is necessary to provide an essential oil module to address the problem that the essential oil module is prone to leakage during use.

During the assembly of the first shell and the third shell through screws, the third threaded hole, and the first threaded hole, the first shell will not easily rotate relative to the second shell, thereby improving the assembly efficiency; at the same time, based on the atomizer sheet being clamped between the first shell and the second shell, and the first shell and the third shell being connected by means of screws and threaded holes, when the distance between the first shell and the third shell becomes smaller and smaller, the first sealing ring and the second sealing ring are both squeezed and elastically deformed, thereby filling the gap between the first shell and the atomizer sheet, and the gap between the second shell and the atomizer sheet, respectively, to ensure the sealing performance.

[0016] In one embodiment, the projection of at least one of the first threaded holes on the second shell is located within the range of the notch, and the third threaded holes are distributed on the limiting portion.

[0019] The essential oil module in the above embodiment further defines that a first annular groove for defining the position of the first sealing ring is provided on the first shell, thereby reducing the possibility that the first sealing ring will deviate from its position during assembly of the first shell and the third shell, thereby affecting the sealing performance.

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0038] Example 1

[0039] like Figure 1 to Figure 2 As shown, this embodiment provides an essential oil module, the essential oil module includes:

[0040] The housing assembly 10 includes a first housing 11, a second housing 12 and a third housing 13. The first housing 11 and the second housing 12 enclose a mounting cavity, and the second housing 12 and the third housing 13 enclose an oil storage cavity 109. The first housing 11 and the second housing 12 are respectively provided with a first through hole 101 and a second through hole 103. The second through hole 103 is connected to the oil storage cavity 109. The second housing 12 and the third housing 13 are both made of hard materials.

[0041] Atomizing sheet 20, the atomizing sheet 20 is installed in the installation cavity, a first sealing ring 30 is provided between the atomizing sheet 20 and the first shell 11, a second sealing ring 40 is provided between the atomizing sheet 20 and the second shell 12, and the first through hole 101, the atomizing sheet 20 and the second through hole 103 cooperate to form an atomizing channel;

[0042] The oil guiding device 60 is installed in the oil storage chamber 109 . The oil guiding device 60 at least partially passes through the second through hole 103 and abuts against the atomizing sheet 20 . The oil guiding device 60 is used to transfer the essential oil in the oil storage chamber 109 to the atomizing sheet 20 .

[0043] Among them, the second shell 12 and the third shell 13 can both be metal shells and non-metal shells. For example, the second shell 12 and the third shell 13 are both plastic shells, and the plastic shells have a certain thickness so that the second shell 12 and the third shell 13 are not easy to elastically deform and have high hardness. Based on the fact that the second shell 12 and the third shell 13 are both hard materials, it can prevent the essential oil module from deforming due to the operation of the hair dryer or being squeezed by external forces, resulting in incomplete sealing of the gap between the second shell 12 and the atomizing sheet 20 or the gap between the second shell 12 and the third shell 13, thereby causing leakage. The oil storage cavity 109 enclosed between the second shell 12 and the third shell 13 can be used to hold essential oils for hair care.

[0044] The atomizing sheet 20 can convert macromolecular essential oil into fine mist particles, which can be blown out along the airflow direction of the hair dryer. The particle-level essential oil blown out by atomization can be fully absorbed by each hair strand to provide good maintenance for the hair strands.

[0045] The first sealing ring 30 can be used to seal the gap between the first housing 11 and the atomizing sheet 20, and the second sealing ring 40 can be used to seal the gap between the second housing 12 and the atomizing sheet 20. The diameter of the first sealing ring 30 and the diameter of the second sealing ring 40 are both smaller than the diameter of the atomizing sheet 20. During assembly, the first sealing ring 30 and the second sealing ring 40 are respectively installed on the front and back of the atomizing sheet 20. When the first housing 11 is connected to the third housing 13, as the distance between the first housing 11 and the third housing 13 is smaller, the first sealing ring 30 and the second sealing ring 40 are both squeezed and elastically deformed, thereby filling the gap between the first housing 11 and the atomizing sheet 20 and the gap between the second housing 12 and the atomizing sheet 20, respectively.

[0046] It should be noted that the first shell 11 and the first sealing ring 30 can be an integrally formed structure, and the back of the first shell 11 is elastic. When the first shell 11 is connected to the third shell 13, the back of the first shell 11 can be in close contact with the non-atomizing area of ​​the atomizing sheet 20.

[0047] The oil guide device 60 can transfer the essential oil in the oil storage chamber 109 to the atomizing sheet 20 through the second through hole 103 for atomization. The oil guide device 60 can be composed of at least a cotton strip 61 and a spring 62. The spring 62 is sleeved on the cotton strip 61. One end of the cotton strip 61 passes through the second through hole 103 and abuts against the atomizing sheet 20. The atomizing sheet 20 absorbs the essential oil in the liquid storage chamber for atomization by connecting with the cotton strip 61. The cotton strip 61 is fixed by the spring 62. The atomizing sheet 20 presses the cotton strip 61 and compresses the spring 62 so that the spring 62 generates an elastic restoring force. Therefore, under the action of the elastic restoring force, even when the user moves and uses the hair dryer, the cotton strip 61 and the atomizing sheet 20 can still be tightly connected. The contact surface between the cotton strip 61 and the atomizing sheet 20 will remain flat and fit, ensuring the stable delivery of the essential oil.

[0048] In the essential oil module of each of the above-mentioned embodiments, the second shell 12 is connected to the third shell 13 and encloses an oil storage chamber 109 for containing essential oil, an oil guide device 60 for transmitting essential oil is installed in the oil storage chamber 109, and an atomizer 20 is installed on the second shell 12. The oil guide device 60 can transmit the essential oil in the oil storage chamber 109 to the atomizer 20 through the second through hole 103 for atomization, so as to convert the macromolecular essential oil into fine mist particles, which can be blown out along the airflow direction of the hair dryer. The particle-level essential oil blown out by the atomization can be fully absorbed by each hair strand to provide good maintenance for the hair strands; a second sealing ring 40 is provided between the atomizer 20 and the second shell 12, and the first shell 11 is arranged on the second shell 12 and the first shell A first sealing ring 30 is provided between the body 11 and the atomizing sheet 20. After the first shell 11 is connected to the third shell 13, the first sealing ring 30 and the second sealing ring 40 are squeezed and elastically deformed, thereby filling the gap between the first shell 11 and the atomizing sheet 20, and the gap between the second shell 12 and the atomizing sheet 20, respectively, to ensure that the essential oil module will not leak when no external force is applied. Since the second shell 12 and the third shell 13 are both made of hard materials, it can be avoided that the essential oil module is deformed due to the operation of the hair dryer or the extrusion of an external force, resulting in incomplete sealing of the gap between the second shell 12 and the atomizing sheet 20 or the gap between the second shell 12 and the third shell 13, thereby causing leakage, thereby improving the sealing performance of the essential oil module.

[0049] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the central axes of the first through hole 101, the atomizing sheet 20 and the second through hole 103 coincide with each other.

[0050] The central axes of the first through hole 101, the atomizing sheet 20 and the second through hole 103 coincide with each other, so that the length of the atomizing channel formed by the three is minimized, thereby reducing the possibility of the atomized essential oil particles re-aggregating due to staying in the atomizing channel for too long.

[0052] Among them, the second shell 12 and the third shell 13 are connected and detachably connected by the cooperation of the screw and the threaded hole, the structure is simple and reliable, and as the screw goes deeper into the first threaded hole, the sealing performance between the second shell 12 and the third shell 13 becomes higher and higher. It should be noted that in other embodiments, the second shell 12 and the third shell 13 can be connected by threaded connection, specifically, the second shell 12 and the third shell 13 are respectively formed with a first thread and a second thread, and the first thread and the second thread can be threadedly connected. In addition, in other embodiments, the third shell 13 can also be a square columnar shell with an opening, etc.

[0054] Among them, a gap 105 is formed between two adjacent second threaded holes 104 on the second shell 12, and a limiting portion matching the shape of the gap 105 is provided on the first shell 11. The limiting portion and the gap 105 form a snap-fit ​​relationship, so that the first shell 11 and the second shell 12 can be quickly positioned. During the assembly of the first shell 11 and the third shell 13 through screws, the third threaded holes 102, and the first threaded holes, the first shell 11 will not easily rotate relative to the second shell 12, thereby improving the assembly efficiency; at the same time, based on the atomizer sheet 20 being sandwiched between the first shell 11 and the second shell 12, and the first shell 11 and the third shell 13 being connected by means of screws and threaded holes, when the distance between the first shell 11 and the third shell 13 becomes smaller and smaller, the first sealing ring 30 and the second sealing ring 40 are both squeezed and elastically deformed, thereby filling the gap between the first shell 11 and the atomizer sheet 20, and the gap between the second shell 12 and the atomizer sheet 20, respectively, to ensure the sealing performance.

[0055] In addition to the features of the above embodiment, this embodiment further defines that: the projection of at least one first threaded hole on the second shell 12 is located within the range of the notch 105, and the third threaded holes 102 are distributed on the limiting portion.

[0056] Among them, the projection of no less than one first threaded hole on the second shell 12 is located within the range of the notch 105. After the limiting portion of the first shell 11 is engaged with the notch 105, the third threaded hole 102 on the limiting portion is axially concentric with the first threaded hole falling within the range of the notch 105.

[0057] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment is further defined as follows: the back water surface 12 is flat.

[0058] In addition to the features of the above embodiment, this embodiment further defines that: a first annular groove matched with the first sealing ring 30 is formed on the first housing 11 , and the first annular groove is distributed around the periphery of the first through hole 101 .

[0059] The first housing 11 is provided with a first annular groove for defining the position of the first sealing ring 30 , so as to reduce the possibility of the first sealing ring 30 being misaligned during the assembly of the first housing 11 and the third housing 13 , thereby affecting the sealing performance.

[0060] In addition to the features of the above embodiment, this embodiment further defines that: a second annular groove matched with the second sealing ring 40 is formed on the second housing 12 , and the second annular groove is distributed around the periphery of the second through hole 103 .

[0061] The second housing 12 is provided with a second annular groove for limiting the position of the second sealing ring 40 , so as to reduce the possibility of the second sealing ring 40 being misaligned during the assembly of the first housing 11 and the third housing 13 , thereby affecting the sealing performance.

[0063] Among them, a third sealing ring 50 is arranged between the third shell 13 and the second shell 12 to improve the sealing performance; at the same time, since the atomizer sheet 20 needs to be electrically connected to the control device through the lead wire, the lead wire of the atomizer sheet 20 needs to be led out from the installation cavity or the oil storage cavity 109. Based on the inward depression of the surface of the third shell 13 to form a wire groove, the second shell 12 and the third sealing ring 50 are respectively provided with a third through hole and a fourth through hole. The lead wire located in the installation cavity can successively pass through the third through hole, the fourth through hole and the first opening and then extend into the wire groove.

The particle-level essential oil blown out by atomization can be fully absorbed by each hair strand to The hair is well maintained; the gap between the atomizer sheet 20 and the second shell 12 is sealed by filling the gap with glue to ensure that the essential oil module will not leak when no external force is applied; at the same time, since the second shell 12 and the third shell 13 are both made of hard materials, the essential oil module can be prevented from being deformed due to the operation of the hair dryer or being squeezed by external force, resulting in incomplete sealing of the gap between the second shell 12 and the atomizer sheet 20 or the gap between the second shell 12 and the third shell 13, thereby causing leakage, thereby improving the sealing performance of the essential oil module.
