[0059] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the specification of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection requested by the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0061] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0062] See also Figures 1 to 3 In a first aspect, the present application provides a sealing structure, which can be used for assembling an atomizer, for example, assembled in a housing of the atomizer and sealedly connected to the housing of the atomizer.

[0063] In this embodiment, the sealing structure includes: a first elastic bracket 10, a second elastic bracket 20, a microphone head 40, an atomizer core assembly 50 and a circuit board 60. The first elastic bracket 10 and the second elastic bracket 20 are sealed and connected to each other to form an elastic bracket structure for installing the microphone head 40 and the atomizer core assembly 50.

[0064] An air duct 30 is formed on the first elastic bracket 10 and the second elastic bracket 20; the air duct 30 is formed by the two, for example, a first portion of the air duct is set on the first elastic bracket 10, and a second portion of the air duct is set on the second elastic bracket 20. After the two are sealed and connected, the first portion of the air duct and the second portion of the air duct are connected to each other to form an air duct 30 that passes through the elastic bracket structure.

[0065] One end of the airway 30 is sealed and connected to the atomizer core assembly 50; the other end of the airway 30 is sealed and connected to the microphone head 40; the circuit board 60 electrically connects the microphone head 40 and the atomizer core assembly 50. The atomizer core assembly 50 and the microphone head 40 are sealed and connected to the airway 30, which means that the two are sealed and connected to the cavity wall of the airway 30, specifically, the gas in the airway 30 can flow into the atomizer core assembly 50, and the negative pressure generated by the airway 30 due to suction can be transmitted to the microphone head 40.

[0066] In this embodiment, the microphone head 40 and the atomizer core assembly 50 can be supported by the first elastic bracket 10 and the second elastic bracket 20 without using a plastic bracket, and after the microphone head 40 and the atomizer core assembly 50 are installed, the two can be sealed and connected at the same time, thereby reducing components, reducing costs, reducing assembly difficulty and reducing occupied space.

[0067] In application, the first elastic bracket 10 and the second elastic bracket 20 can be made of elastic materials such as rubber, silicone, etc.

[0068] For more specific examples, see Figures 2 to 4 The airway 30 includes an atomizing hole 31 and a microphone hole 32. It should be noted that the atomizing hole 31 and the microphone hole 32 are part of the airway 30, so the two are interconnected; correspondingly, the atomizing hole 31 and the microphone hole 32 are also interconnected with other parts of the airway 30, such as the intermediate cavity 33 and the gas inlet hole 34 described below.

[0069] The atomization hole 31 is disposed on the first elastic bracket 10 ; the atomization core assembly 50 is sealed and inserted into the atomization hole 31 , that is, the outer periphery of the atomization core assembly 50 is in sealing contact with the hole wall of the atomization hole 31 .

[0070] The microphone hole 32 is arranged on the second elastic bracket 20 ; the microphone component 40 is sealed and inserted into the microphone hole 32 , that is, the outer periphery of the microphone component 40 is sealed and connected to the hole wall of the microphone hole 32 .

[0071] In practical applications, taking the atomizer placed horizontally as an example, the atomizer core assembly 50 is generally arranged above the circuit board 60 and the microphone head 40. Therefore, in this embodiment, the first elastic bracket 10 can be arranged above the second elastic bracket 20; correspondingly, the atomization hole 31 penetrates the first elastic bracket 10 in the vertical direction; the microphone head hole 32 penetrates the second elastic bracket 20 in the vertical direction.

[0072] In practical applications, the circuit board 60 can be fixedly installed by being mounted on a housing or a base; the microphone component 40 can also be fixedly connected to the circuit board 60 through a bracket or directly, so that after the microphone component 40 is inserted into the microphone hole 32, the position of the circuit board 60 is also fixed.

[0073] In this embodiment, a circuit board clamping position (not shown) is provided on the second elastic bracket 20. Specifically, the circuit board clamping position and the microphone hole 32 can be both provided below the second elastic bracket 20. The circuit board 60 is installed on the circuit board clamping position, so that after the microphone piece 40 on the circuit board 60 is inserted into the microphone hole 32, the circuit board 60 is also fixedly connected with the second elastic bracket 20, so that the installation structure of the circuit board 60 is more stable.

[0074] In one embodiment, the air passage 30 further includes: an intermediate cavity 33; the intermediate cavity 33 is enclosed by the first elastic bracket 10 and the second elastic bracket 20; a pole hole 22 is provided on the second elastic bracket 20; a pole 61 is provided on the circuit board 60; the pole 61 passes through the pole hole 22 and extends into the intermediate cavity 33; the atomizer core assembly 50 is electrically connected to the pole 61.

[0075] Specifically, the middle cavity 33 serves as a gas inlet cavity and a component installation cavity.

[0076] The role of the middle cavity 33 as a gas inlet cavity is reflected in that: a gas inlet hole 34 is also provided on the second elastic bracket 20; when the atomizer is sucked, the microphone hole 32 generates negative pressure so that the circuit board 60 controls the atomizer core assembly 50 to start, and at the same time, the gas enters the middle cavity 33 from the gas inlet hole 34 and then enters the atomizer core assembly 50. That is, the middle cavity 33 can simultaneously connect the microphone hole 32 and the gas inlet hole 34, allowing gas to enter without affecting the negative pressure generated by the microphone hole 32.

[0077] The function of the middle cavity 33 as a component installation cavity is reflected in that the pole 61 passes through the pole hole 22 and enters the middle cavity 33 , thereby facilitating the electrical connection between the pole 61 and the atomizer core assembly 50 .

[0078] Correspondingly, an adjusting member 110 may also be included; the adjusting member 110 covers the gas inlet hole 34 and can slide relative to the second elastic bracket 20; the opening of the gas inlet hole 34 can be adjusted by the adjusting member 110, thereby adjusting the air intake of the gas inlet hole 34.

[0079] In practical applications, the atomizer core assembly 50 can be electrically connected to the pole 61 in, for example, first installing the atomizer core assembly 50, that is, after the pins of the atomizer core assembly 50 are electrically connected to the pole 61, then covering the first elastic bracket 10 to complete the sealed connection between the first elastic bracket 10 and the second elastic bracket 20 and the atomizer core assembly 50.

[0080] The atomizer core assembly 50 can also be electrically connected to the pole 61 in, for example, a pin hole 13 is provided at the bottom of the first elastic bracket 10; during the assembly process, the pin of the atomizer core assembly 50 can be first inserted into the pin hole 13, and then the pole 61 of the circuit board 60 can be passed through the pole hole 22; the position of the pin hole 13 corresponds to the position of the pole hole 22, and when the first elastic bracket 10 and the second elastic bracket 20 are sealed and connected, the pole 61 will penetrate into the pin hole 13 to achieve conductive connection between the pole 61 and the pin.

[0081] As an implementation mode, the second elastic bracket 20 is provided with a groove 23 ; the first elastic bracket 10 is provided with a protrusion 11 ; a hollow groove 12 is provided in the protrusion 11 ; the protrusion 11 is inserted into the groove 23 ; the hollow groove 12 and the groove 23 form an intermediate cavity 33 .

[0082] That is, in this embodiment, the first elastic bracket 10 and the second elastic bracket 20 are sealed and connected by a snap-in method, which has the effect of easy assembly. Among them, the outer periphery of the protrusion 11 and / or the inner periphery of the groove 23 can be provided with an elastic sealing ring to improve the sealing connection effect of the two.

[0083] In one embodiment, a battery support portion 24 is provided on the side of the second elastic bracket 20; the battery support portion 24 is used to place the battery 100, and specifically, it can abut against the battery 100 after the battery 100 is installed in the housing to fix the battery 100. The side of the second elastic bracket 20 refers to the side of the second elastic bracket 20 in the horizontal direction when the atomizer is placed horizontally.

[0084] The battery support portion 24 is provided with a lead through hole 21 penetrating the second elastic bracket 20 ; the lead through hole 21 can allow the lead 62 on the circuit board 60 to pass through, thereby realizing the mutual electrical connection between the circuit board 60 and the battery 100 .

[0085] In this embodiment, corresponding to the battery support portion 24 , the first elastic bracket 10 may be provided with a notch to avoid the battery support portion 24 , that is, the first elastic bracket 10 may be provided with a structure with a horizontal area smaller than that of the second elastic bracket 20 .

[0086] In another embodiment, the structure for supporting the battery can be arranged on the first elastic bracket 10, such as Figure 6 As shown, a battery placement portion 101 is provided on the side of the first elastic bracket 10 ; the battery placement portion is used for placing the battery 100 .

[0087] That is, in this embodiment, the second elastic bracket 20 can be configured to have a structure with a horizontal area smaller than that of the first elastic bracket 10 , and the second elastic bracket 20 can be configured to be installed in the first elastic bracket 10 .

[0088] Corresponding to the embodiment of setting a circuit board engaging position, in this solution, the first elastic bracket 10 can extend toward the side where the second elastic bracket 20 is located to form a circuit board engaging position for the circuit board 60 to engage.

[0089] The second aspect of the present application provides an atomizer, see Figure 7 The atomizer comprises: a first shell 70 and any of the above-mentioned sealing structures; the first elastic bracket 10 and / or the second elastic bracket 20 in the sealing structure are inserted into the first shell 70 and are sealed and connected to the first shell 70 .

[0090] In this embodiment, taking the sealed connection between the first elastic bracket 10 and the first shell 70 as an example, when the atomizer is placed horizontally, the first shell 70 is located above the first elastic bracket 10, and the first elastic bracket 10 is fully or partially extended into the first shell 70, so that the outer periphery of the first elastic bracket 10 is sealed and abutted against the inner circumferential wall of the first shell 70; wherein the first elastic bracket 10 and the first shell 70 form a liquid storage chamber for storing atomized liquid.

[0091] As an implementation manner, the second elastic bracket 20 located outside the first shell 70 may be installed with a bottom shell on the outer periphery, and the second elastic bracket 20 and components such as the circuit board 60 are protected by the bottom shell.

[0092] Taking the sealed connection between the second elastic bracket 20 and the first shell 70 as an example, the first elastic bracket 10 and the second elastic bracket 20 may both extend into the first shell 70, and the outer periphery of the side of the second elastic bracket 20 is in sealed contact with the inner peripheral wall of the first shell 70, so that the first shell 70 provides protection for both the first elastic bracket 10 and the second elastic bracket 20. Among them, the first elastic bracket 10 may be arranged in a manner that the area on the horizontal plane is smaller than the area on the horizontal plane of the second elastic bracket 20, so that it is convenient for it to extend into the first shell 70, and at the same time, a card block protruding inwardly may be arranged inside the first shell 70, and the card block is sealedly connected to the first elastic bracket 10, so that the first elastic bracket 10 and the second elastic bracket 20 are both sealedly connected to the first shell 70.

[0093] For more specific examples, see Figure 8 The atomizer further includes: a second shell 80 and a base 90; the base 90 and the second shell 80 are detachably connected, and the base 90 and the second shell 80 form an installation cavity; the first shell 70 and the sealing structure are arranged in the installation cavity.

[0094] In this embodiment, the first shell 70 is used as a storage tank for the atomized liquid. After the assembly with the sealing structure is completed, the first shell 70, the battery 100 and the sealing structure are all installed in the installation cavity, and the installation cavity is closed by the base 90. The base 90 and the second shell 80 can be detachably connected in a manner such as a snap connection.

[0095] In further embodiments, see Fig. 9 and Figure 8 A display screen 120 for displaying the amount of atomized liquid and / or the power level of the battery 100 may be provided on the second housing 80 .

[0096] Furthermore, the second housing 80 may be sleeved with a third housing 130 ; the third housing 130 may be a transparent housing, which protects the display screen 120 and the second housing 80 , and facilitates the user to view the display screen 120 .
