Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0029] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0030] It should be understood that "some embodiments" mentioned throughout the specification mean that specific features, structures, or characteristics related to the embodiments are included in at least one embodiment of the present application. Therefore, "in some embodiments" that appears throughout the specification does not necessarily refer to the same embodiments. In addition, these specific features, structures, or characteristics can be combined in one or more embodiments in any suitable manner.

[0031] The following details a nebulizer and a nebulizing device provided by the present application by enumerating specific embodiments.

[0032] Referring Figures 1 to 6 , a nebulizer provided by an embodiment of the present application includes: an oil storage chamber housing 1 and an atomizer core housing 2; a first limiting portion 10 is provided on the oil storage chamber housing 1, and a second limiting portion 20 is provided on the atomizer core housing 2; both the first limiting portion 10 and the second limiting portion 20 are arranged along the length direction of the nebulizer, and the first limiting portion 10 is cooperatively connected with the second limiting portion 20.

[0033] Specifically, the nebulizer is a key component in the nebulizing device, Figure 6 shows an exploded view of the structure of a nebulizer. As Figure 6 shown, the nebulizer includes an oil storage chamber 100, an atomizer core assembly 200, a mouthpiece 3, etc. The oil storage chamber 100 is used to store the atomization matrix for the atomizer core assembly 200 to heat and atomize. The housing of the oil storage chamber 100 is the oil storage chamber housing 1, and the oil storage chamber housing 1 is usually made of a transparent or semi-transparent material, such as polycarbonate, ethylene glycol modified polyethylene terephthalate, etc., to facilitate observing the remaining amount of the atomization matrix in the oil storage chamber 100. The atomizer core assembly is composed of an atomizer core 21, a heating wire 22, an atomization outer tube 23, etc. The accommodation space inside the atomization outer tube 23 accommodates components such as the atomizer core 21, the heating wire 22, and the oil guiding cotton. The atomization outer tube 23 can play a role in fixing and supporting the components accommodated therein. At the same time, an oil passing port is also provided on the atomization outer tube 23, which is used to participate in the liquid guiding, air intake, etc. processes of the nebulizing device, improving the use experience and smoke effect of the nebulizing device. The atomizer core 21 can adopt a ceramic core or a cotton core. The heating wire 22 is embedded inside the atomizer core 21. The heating wire 22 is heated by an electric current, transferring heat energy to the atomization matrix, so that the atomization matrix evaporates and heats to achieve the atomization effect of the atomization matrix. The oil guiding cotton is made of organic cotton, which guides the atomization matrix from the oil storage chamber 100 to the periphery of the heating wire 22, ensuring that the heating wire 22 can continuously supply the atomization matrix for atomization. The mouthpiece 3 is used for the user to inhale the atomized atomization matrix. The atomizer core housing 2 is the housing of the atomizer core assembly 200, and the housing interior is provided with an atomizer core 21, a heating wire 22, an atomization outer tube 23, etc.

[0034] Figure 1 and Figure 3 respectively show schematic diagrams of a nebulizer in a separated state. AsFigure 1 and Figure 3 As shown, the oil tank housing 1 is separated from the atomizing core housing 2. A first limiting portion 10 (hidden inside the oil tank housing 1) is provided on the oil tank housing 1, and a second limiting portion 20 is provided on the atomizing core housing 2. Both the first limiting portion 10 and the second limiting portion 20 are arranged along the length direction of the atomizer. The length direction of the atomizer is as Figure 1 the X direction in [reference], and the atomizer has the largest length dimension along this direction. The first limiting portion 10 is cooperatively connected with the second limiting portion 20. The first limiting portion 10 and the second limiting portion 20 can be in the form of shaft-hole fit or groove fit. The specific form is not limited in this embodiment. Since both the first limiting portion 10 and the second limiting portion 20 are arranged along the length direction of the atomizer, during the separation and connection of the oil tank housing 1 and the atomizing core housing 2, the first limiting portion 10 and the second limiting portion 20 gradually complete the cooperative connection, which plays a limiting role on the oil tank housing 1 and the atomizing core housing 2, and prevents the oil tank housing 1 and the atomizing core housing 2 from tilting left and right. Figure 5 Fig. [reference] shows a schematic diagram of an atomizer in a connected state. As Figure 5 shown, after the first limiting portion 10 is cooperatively connected with the second limiting portion 20, the atomizing core housing 2 is hidden inside the oil tank housing 1, and the atomizer can be activated for use in this state. In this embodiment, the first limiting portion 10 and the second limiting portion 20 can be in interference fit, which increases the structural stability of the atomizer.

[0035] In summary, the atomizer of the present application is provided with a first limiting portion 10 arranged along the length direction of the atomizer on the oil tank housing 1, and a second limiting portion 20 arranged along the length direction of the atomizer on the atomizing core housing 2. During the separation and connection of the oil tank housing 1 and the atomizing core housing 2, the first limiting portion 10 and the second limiting portion 20 gradually achieve cooperative connection, which plays a limiting role on the oil tank housing 1 and the atomizing core housing 2, prevents the oil tank housing 1 and the atomizing core housing 2 from tilting left and right, and thus helps the smooth separation and connection of the oil tank housing 1 and the atomizing core housing 2, and ensures the activation effect of the atomizer after connection.

[0036] Referring to Figures 1 to 4 , in some optional embodiments, the oil tank housing 1 includes a first side wall and a second side wall oppositely arranged along the thickness direction of the atomizer, and the first limiting portion 10 is provided on the first side wall and / or the second side wall; the atomizing core housing 2 includes a third side wall and a fourth side wall oppositely arranged along the thickness direction of the atomizer, and the second limiting portion 20 is provided on the third side wall and / or the fourth side wall.

[0037] Specifically, the thickness direction of the atomizer is as Figure 1 and Figure 3As shown in the Z direction in the figure, the oil storage tank housing 1 has a surrounding side wall, where the side wall includes a first side wall and a second side wall that are oppositely arranged in the Z direction. The areas of the first side wall and the second side wall are relatively large. The first limiting portion 10 can be provided only on the first side wall, or only on the second side wall, or respectively on the first side wall and the second side wall. Specifically, it can be set according to the limiting requirements of the oil storage tank housing 1 and the atomizing core housing 2, and this embodiment does not limit this. Correspondingly, the atomizing core housing 2 has a surrounding side wall, where the side wall includes a third side wall and a fourth side wall that are oppositely arranged in the Z direction. The areas of the third side wall and the fourth side wall are relatively large. The second limiting portion 20 can be provided only on the third side wall, or only on the fourth side wall, or respectively on the third side wall and the fourth side wall. Specifically, it can be set according to the limiting requirements of the oil storage tank housing 1 and the atomizing core housing 2, and this embodiment does not limit this. Of course, the positions of the first limiting portion 10 and the second limiting portion 20 need to correspond to ensure their mating connection. In this embodiment, the first limiting portion 10 and the second limiting portion 20 are provided on the side walls with relatively large areas, which is more convenient for the processing and design of the first limiting portion 10 and the second limiting portion 20, and also helps to achieve a better limiting effect.

[0038] Referring to Figures 1 to 4 , in some alternative embodiments, at least two first limiting portions 10 are respectively provided on the first side wall and / or the second side wall, and the at least two first limiting portions 10 are spaced apart, as Figure 1 and Figure 3 respectively show the implementation manners in which two first limiting portions 10 are provided on the first side wall. Correspondingly, at least two second limiting portions 20 are respectively provided on the third side wall and / or the fourth side wall, and the at least two second limiting portions 20 are spaced apart, as Figure 1 and Figure 3 respectively show the implementation manners in which two second limiting portions 20 are provided on the third side wall.

[0039] Among them, the specific number and spacing distance of the first limiting portion 10 and the second limiting portion 20 can be determined according to the width dimension of the atomizer, the width dimensions of the first limiting portion 10 and the second limiting portion 20 themselves, etc. The above width dimensions are the dimensions in the width direction of the atomizer, and the width direction of the atomizer is as Figure 1 and Figure 3As shown in the Y direction in [description], if the width dimensions of the first limiting part 10 and the second limiting part 20 themselves are small and the width dimension of the atomizer is large, the number of the first limiting part 10 and the second limiting part 20 can be set to be large, or the interval distance can be large; if the width dimensions of the first limiting part 10 and the second limiting part 20 themselves are large and the width dimension of the atomizer is small, the number of the first limiting part 10 and the second limiting part 20 can be set to be small, or the interval distance can be small. Since the width of the atomizer is usually about 10 mm to 13 mm, when there are two first limiting parts 10 and two second limiting parts 20 respectively, the interval distance between the two first limiting parts 10 and the two second limiting parts 20 can be set to be about 3 mm to 5 mm.

[0040] Referring to Figures 1 to 4 , in some optional embodiments, at least two of the first limiting parts 10 and at least two of the second limiting parts 20 are symmetrically arranged along the central axis of the atomizer. The central axis of the atomizer is as shown by L in Figure 2 and Figure 4 . Figure 2 is Figure 1 the view of the atomizer shown along the A direction, Figure 4 is Figure 2 the view of the atomizer shown along the B direction. The central axis is arranged along the length direction of the atomizer. Two or more first limiting parts 10 and the second limiting parts 20 are symmetrically arranged along the central axis of the atomizer respectively, so that during the relative movement of the oil storage housing 1 and the atomization core housing 2, the forces on the first limiting part 10 and the second limiting part 20 are more uniform, which helps to improve the limiting effect of the first limiting part 10 and the second limiting part 20 on the oil storage housing 1 and the atomization core housing 2 and improve the connection reliability of the oil storage housing 1 and the atomization core housing 2.

[0041] Referring to Figures 1 to 4 , in some optional embodiments, the first limiting part 10 is a groove formed on the surface of the oil storage housing 1, and the depth of the groove does not exceed 50% of the wall thickness of the oil storage housing 1 to avoid affecting the structural stability of the oil storage housing 1. The second limiting part 20 is a protrusion formed on the surface of the atomization core housing 2; alternatively, the first limiting part 10 is a protrusion formed on the surface of the oil storage housing 1, and the second limiting part 20 is a groove formed on the surface of the atomization core housing 2, and the depth of the groove does not exceed 50% of the wall thickness of the atomization core housing 2 to avoid affecting the structural stability of the atomization core housing 2. In the embodiment, the protruding height of the protrusion is adapted to the depth of the groove, and the protrusion is embedded in the groove to realize the fitting connection between the first limiting part 10 and the second limiting part 20. The first limiting part 10 and the second limiting part 20 adopt the fitting form of the protrusion and the groove, which has a simple structure and is convenient for processing, and helps to control the processing cost of the oil storage housing 1 and the atomization core housing 2.

[0042] Referring to Figures 1 to 4, in some alternative embodiments, along the thickness direction of the atomizer, the cross-section of the groove and the cross-section of the protrusion are rectangular structures or arc-shaped structures. As Figure 1 and Figure 2 show the ways in which the cross-section of the groove and the cross-section of the protrusion are rectangular structures. The protrusion is in the form of a strip structure, and the groove is a rectangular groove. The width of the groove can be slightly larger than the width of the protrusion to ensure that the protrusion can be smoothly embedded in the groove. As Figure 3 and Figure 4 show the ways in which the cross-section of the groove and the cross-section of the protrusion are arc-shaped structures. The protrusion is in the form of a semi-cylindrical structure, and the groove is an arc-shaped groove. The diameter of the groove can be slightly larger than the diameter of the protrusion to ensure that the protrusion can be smoothly embedded in the groove.

[0043] Referring to Figures 1 to 4 , in some alternative embodiments, along the width direction of the atomizer, the width dimensions of the first limiting portion 10 and the second limiting portion 20 are 1 mm to 1.5 mm. The width direction of the atomizer is as shown by the Y direction in Figure 1 and Figure 3 . That is, the dimensions of the first limiting portion 10 and the second limiting portion 20 along the Y direction are 1 mm to 1.5 mm. Exemplarily, when the first limiting portion 10 is a groove and the second limiting portion 20 is a protrusion, the width dimension of the first limiting portion 10 can be set to 1.1 mm, and the width dimension of the second limiting portion 20 can be set to 1 mm to ensure that the second limiting portion 20 can be smoothly embedded in the first limiting portion 10 and effectively cooperate with the first limiting portion 10. In this embodiment, the dimensions of the first limiting portion 10 and the second limiting portion 20 within this range can achieve effective limiting of the oil storage housing 1 and the atomization core housing 2, and at the same time will not overly affect the original structures of the oil storage housing 1 and the atomization core housing 2.

[0044] Referring to Figures 1 to 4 , in some alternative embodiments, along the length direction of the atomizer, the length dimensions of the first limiting portion 10 and the second limiting portion 20 are not less than 1.5 mm. The length direction of the atomizer is as shown by the X direction in Figure 1 and Figure 3 . That is, the dimensions of the first limiting portion 10 and the second limiting portion 20 along the X direction are not less than 1.5 mm. Since relative movement occurs between the oil storage housing 1 and the atomization core housing 2 along the X direction during the separation or connection of the oil storage housing 1 and the atomization core housing 2, the dimensions of the first limiting portion 10 and the second limiting portion 20 along the X direction are set to be not less than 1.5 mm to ensure that the first limiting portion 10 and the second limiting portion 20 can effectively limit the oil storage housing 1 and the atomization core housing 2.

[0045] Referring to Figure 7 and Figure 8, in some alternative embodiments, the atomizing core housing 2 is disposed within the oil reservoir housing 1. At least one side of the oil reservoir housing 1 along the width direction of the atomizer ( Figure 1 and Figure 2 the Y direction mentioned above) is further provided with a first positioning portion 11. At least one side of the atomizing core housing 2 along the width direction of the atomizer is further provided with a second positioning portion 24. The first positioning portion 11 and the second positioning portion 24 are cooperatively connected to restrict relative movement between the oil reservoir housing 1 and the atomizing core housing 2. Specifically, during the process of installing the atomizing core housing 2 into the oil reservoir housing 1, the atomizing core housing 2 moves relative to the oil reservoir housing 1 along the length direction of the atomizer ( Figure 1 and Figure 2 the X direction mentioned above). When the first positioning portion 11 moves to be cooperatively connected with the second positioning portion 24, the atomizing core housing 2 can no longer move relative to the oil reservoir housing 1. Thus, the positioning of the oil reservoir housing 1 and the atomizing core housing 2 is achieved through the cooperative connection between the first positioning portion 11 and the second positioning portion 24.

[0046] Specifically, as Figure 8 shown, the first positioning portion 11 can be a hole or a groove provided on the oil reservoir housing 1 (not shown in the figure). As Figure 7 shown, the second positioning portion 24 can be a protrusion provided on the atomizing core housing 2. The protrusion is embedded in the hole or the groove and is snap-fitted therewith, thereby achieving the cooperative connection between the first positioning portion 11 and the second positioning portion 24. The above-mentioned hole or groove and the protrusion can be dot-shaped structures, block-shaped structures, linear structures, etc., as long as the shape structures of the two are adapted to each other. The specific structure is not limited in this embodiment.

[0047] The first positioning portion 11 can be disposed on one side of the oil reservoir housing 1. Correspondingly, the second positioning portion 24 is also disposed on one side of the atomizing core housing 2, thereby achieving single-sided positioning during the installation process. Such a setting helps to simplify the structures of the oil reservoir housing 1 and the atomizing core housing 2 and is more convenient for processing. Or, the first positioning portion 11 can be disposed on opposite sides of the oil reservoir housing 1. Correspondingly, the second positioning portion 24 is also disposed on opposite sides of the atomizing core housing 2, thereby achieving double-sided positioning during the installation process. Such a setting helps to strengthen the connection reliability between the first positioning portion 11 and the second positioning portion 24 and ensure the positioning effect of the oil reservoir housing 1 and the atomizing core housing 2. In addition, the number of the first positioning portion 11 and the second positioning portion 24 can be one, two or more. If the number of the first positioning portion 11 and the second positioning portion 24 is more, the positioning effect is better. Specifically, it can be set according to actual needs, and this embodiment does not limit this.

[0048] The embodiment of the present application further provides an atomizing device, including a power supply assembly and the atomizer described in any one of the foregoing items. The power supply assembly is detachably connected to the atomizer.

[0049] Specifically, the power supply component is the main part of the atomization device. Inside the power supply component, there are a battery component, a control component, a switch component, an indicator light, etc. The battery component is used to provide the power required for the atomization device. The control component integrates a control circuit and is responsible for the overall control of the atomization device, including the charge and discharge management of the battery, the adjustment of the output power, etc. The switch component is used to control the opening or closing of the atomization device, and the indicator light is used to display the working state of the atomization device, such as the charging state, the battery power, etc. The atomizer and the power supply component can be fixed by plugging. The atomizer includes an oil storage chamber 100, an atomization core component 200, a mouthpiece 3, etc. The atomization core component 200 heats the atomization matrix stored in the oil storage chamber 100 to form smoke, enabling users to inhale through the mouthpiece 3.

[0050] Finally, it should also be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or terminal device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or terminal device comprising the element.

[0051] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
