Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and more particularly to an electronic atomization device. Background Technology

[0002] An electronic atomizing device is an electronic product that generates an aerosol by atomizing a liquid matrix for users to inhale. An electronic atomizing device typically includes a mouthpiece, an atomizer, and a power supply unit. The atomizer contains a coil for atomizing the liquid matrix.

[0003] In existing electronic atomizing devices with dual atomizing components, the air intake structures of the two components are interconnected. This leads to a problem: if the airflow channel of one of the atomizing components becomes blocked, leakage of the liquid matrix can easily occur, reducing the user experience. Utility Model Content

[0004] The purpose of this application is to provide an electronic atomizing device to reduce leakage of liquid matrix and improve the user experience.

[0005] This application provides an electronic atomizing device, including a housing, on which an air inlet and an air outlet are provided; the housing contains:

[0006] The air intake chamber includes a first air intake chamber and a second air intake chamber that are separated from each other; both the first air intake chamber and the second air intake chamber are connected to the air inlet.

[0007] The atomizing assembly includes a first atomizing assembly and a second atomizing assembly that are independent of each other; both the first atomizing assembly and the second atomizing assembly include an airflow inlet, an airflow outlet, and an atomizing core, wherein the atomizing core is used to atomize a liquid matrix and is disposed between the airflow inlet and the airflow outlet;

[0008] The airflow inlet of the first atomizing component is connected to the first air intake chamber, the airflow inlet of the second atomizing component is connected to the second air intake chamber, and the airflow outlets of the first atomizing component and the second atomizing component are both connected to the air outlet.

[0009] The above electronic atomizing device provides air intake to the two atomizing components one-to-one through two separate air intake chambers. On the one hand, this ensures the smoothness of the airflow channel where the atomizing components are located, reduces suction resistance, and improves the user's vaping experience. On the other hand, it can reduce the leakage of liquid matrix when the airflow channel where the atomizing components are located is blocked, thus improving the user's experience.

[0025] like Figures 1-4 This application provides an electronic atomizing device 10, which includes a housing 101. The housing 101 has an air inlet 101a and an air outlet 101b. The housing 101 contains:

[0026] The air intake chamber 102 includes a first air intake chamber 102a and a second air intake chamber 102b that are separated from each other; both the first air intake chamber 102a and the second air intake chamber 102b are connected to the air intake port 101a.

[0027] The atomizing component 103 includes a first atomizing component 103a and a second atomizing component 103b that are independent of each other; both the first atomizing component 103a and the second atomizing component 103b include an airflow inlet, an airflow outlet and an atomizing core, wherein the atomizing core is used to atomize the liquid matrix and is disposed between the airflow inlet and the airflow outlet;

[0028] The airflow inlet of the first atomizing component 103a is connected to the first air intake chamber 102a, the airflow inlet of the second atomizing component 103b is connected to the second air intake chamber 102b, and the airflow outlets of the first atomizing component 103a and the second atomizing component 103b are both connected to the air outlet 101b.

[0029] The above-mentioned electronic atomizing device 10 provides air intake to the two atomizing components one-to-one through two separate air intake chambers. On the one hand, it can ensure the smoothness of the airflow channel where the atomizing components are located, reduce the suction resistance, and improve the user's vaping experience; on the other hand, it can reduce the leakage of liquid matrix when the airflow channel where the atomizing components are located is blocked, thus improving the user's experience.

[0030] In one example, the housing 101 can be formed integrally or composed of multiple parts. For example, the housing 101 can be composed of a top cover and a main housing. The air inlet 101a is located on the bottom wall of the main housing, while the air outlet 101b is located on the top cover. The user can inhale the aerosol generated by the atomizing component through the air outlet 101b.

[0031] In one example, a liquid storage chamber 104 for storing a liquid matrix is ​​also provided inside the housing 101;

[0032] The first atomizing component 103a and the second atomizing component 103b also include a transmission tube. The airflow inlet is located at one end of the transmission tube, the airflow outlet is located at the other end of the transmission tube, and the atomizing core is located inside the transmission tube and communicates with the liquid storage chamber 104 through the liquid inlet on the transmission tube.

[0033] In specific implementation, both the upper and lower ends of the liquid storage chamber 104 are provided with sealing elements. The upper end of the transmission tube of the first atomizing component 103a is kept at the sealing element at the upper end of the liquid storage chamber 104, and the airflow outlet at the upper end of the transmission tube of the first atomizing component 103a is connected to the air outlet 101b. The lower end of the transmission tube of the first atomizing component 103a is kept at the sealing element at the lower end of the liquid storage chamber 104, and the airflow inlet at the lower end of the transmission tube of the first atomizing component 103a is connected to the first air inlet chamber 102a. The atomizing core of the first atomizing component 103a is disposed in the transmission tube of the first atomizing component 103a and is connected to the liquid storage chamber 104 through the liquid inlet of the transmission tube of the first atomizing component 103a. Similar to the first atomizing component 103a, the upper end of the transmission tube of the second atomizing component 103b is sealed at the upper end of the liquid storage chamber 104, and the airflow outlet at the upper end of the transmission tube of the second atomizing component 103b is connected to the air outlet 101b; the lower end of the transmission tube of the second atomizing component 103b is sealed at the lower end of the liquid storage chamber 104, and the airflow inlet at the lower end of the transmission tube of the second atomizing component 103b is connected to the second air inlet chamber 102b; the atomizing core of the second atomizing component 103b is disposed inside the transmission tube of the second atomizing component 103b and is connected to the liquid storage chamber 104 through the liquid inlet of the transmission tube of the second atomizing component 103b. The above structure is designed as a single liquid storage chamber dual atomizing component. In other specific implementations, a dual liquid storage chamber dual atomizing component structure design can also be adopted.

[0034] In one example, a battery cell 105 for providing power is also disposed within the housing 101. The battery cell 105 may be a lithium-ion battery. Alternatively, the battery cell 105 may be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery, such as a lithium cobalt, lithium iron phosphate, lithium titanate, or lithium polymer battery. The battery cell 105 is electrically connected to the atomizing core of the first atomizing assembly 103a and the atomizing core of the second atomizing assembly 103b. The battery cell 105 and the liquid storage chamber 104 are arranged sequentially along the width direction of the electronic atomizing device 10.

[0035] In one example, a circuit 106 is also provided within the housing 101 to control the overall operation of the electronic atomizing device 10. Specifically, the circuit 106 controls not only the operation of the battery cell 105 and the atomizing coil, but also the operation of other components in the electronic atomizing device 10. Furthermore, the circuit 106 can determine whether the electronic atomizing device 10 is operable by checking the state of its components; for example, it can control the electronic atomizing device 10 to start heating when a user's key press is detected. The circuit 106 includes at least one control unit. The control unit may include a logic gate array, or may include a combination of a general-purpose microcontroller and a memory for storing executable programs in the microcontroller. Furthermore, those skilled in the art will understand that the circuit 106 may include another type of hardware.

[0036] In one example, the first atomizing component 103a and the second atomizing component 103b are independent of each other. The first atomizing component 103a and the second atomizing component 103b are structurally independent and spaced apart from each other; the first atomizing component 103a and the second atomizing component 103b are also electrically independent, and they can start and run together or operate independently.

[0037] In one example, the first atomizing component 103a and the second atomizing component 103b can adopt the same structural design, which can simplify the structural design of the electronic atomizing device 10 and facilitate manufacturing.

[0038] For ease of understanding, the structure of the atomizing component will be explained below using the first atomizing component 103a as an example:

[0039] like Figures 5-6 As shown, the first atomizing component 103a includes a transmission tube 103a1 and an atomizing core disposed within the transmission tube 103a1.

[0040] The transmission tube 103a1 has a slender tubular structure. The opening at the upper end of the transmission tube 103a1 constitutes the airflow outlet of the first atomizing component 103a, and the opening at the lower end of the transmission tube 103a1 constitutes the airflow inlet of the first atomizing component 103a. A liquid inlet 103a11 is provided on the side wall of the transmission tube 103a1.

[0041] The atomizing core includes a liquid guiding element 103a2 and a heating element 103a3. The liquid guiding element 103a2 can draw liquid matrix from the liquid storage chamber 104 through the liquid inlet 103a11 and transfer the liquid matrix to the heating element 103a3. The heating element 103a3 can be heated by an electric current supply and transfers heat to the liquid matrix in contact with the heating element 103a3 to heat the liquid matrix, thereby generating an aerosol.

[0042] The liquid-conducting element 103a2 is constructed as a tubular structure, but it can also be a plate-like structure or other regular or irregular shapes. The liquid-conducting element 103a2 can be made of a flexible fibrous material, such as cotton fibers, non-woven fabric, or sponge. Alternatively, in other examples, the liquid-conducting element 103a2 can also be a rigid porous body, such as porous ceramics or porous glass.

[0043] The heating element 103a3 is disposed near the inner surface of the liquid guiding element 103a2, and can be attached to the inner surface of the liquid guiding element 103a2, or partially or completely embedded in the liquid guiding element 103a2. The heating element 103a3 can be a resistance heating mesh, a resistance heating coil, etc. The heating element 103a3 can be made of a material with suitable temperature coefficient of resistance characteristics, such as stainless steel 316, titanium, nickel, nickel-chromium alloy, etc. In one example, the heating element 103a3 can be wound from a sheet or mesh substrate, and the wound heating element 103a3 is a non-closed tubular structure in the circumferential direction, that is, a tubular structure with a side opening extending along the length direction of the first atomizing assembly 103a. Leads 103a4 are welded or arranged at both ends of the heating element 103a3 for guiding current on the heating element 103a3. It is understood that the leads 103a4 typically include a positive lead and a negative lead.

[0044] In one example, the first air intake chamber 102a and the second air intake chamber 102b are separated from each other. Separation from each other means that the gas in the first air intake chamber 102a cannot flow directly into the second air intake chamber 102b, and the gas in the second air intake chamber 102b cannot flow directly into the first air intake chamber 102a, thereby ensuring the smoothness of the airflow channels in their respective locations and reducing suction resistance.

[0045] Please combine Figures 7-10 To understand this further, the housing 101 is also provided with a base 107, a bracket 108, and a seal 109.

[0046] The base 107 and the bracket 108 are detachably connected. In specific implementation, the base 107 is provided with a snap-fit ​​buckle 107a, and the bracket 108 is provided with a snap-fit ​​hole 108a. The snap-fit ​​buckle 107a and the snap-fit ​​hole 108a cooperate to realize the snap-fit ​​connection between the base 107 and the bracket 108.

[0047] After the base 107 and the bracket 108 are connected, they together define and form the first air intake chamber 102a and the second air intake chamber 102b. In a specific implementation, both the base 107 and the bracket 108 have openings communicating with their internal hollow portions. After the base 107 and the bracket 108 are connected, the internal hollow portions of the base 107 and the bracket 108 together define and form the first air intake chamber 102a and the second air intake chamber 102b. A partition 107b is provided inside the base 107; after the base 107 and the bracket 108 are connected, the partition 107b abuts against the inner surface of the bracket 108, thereby separating the first air intake chamber 102a and the second air intake chamber 102b. The seal 109 is placed on the base 107. After the base 107 is connected to the bracket 108, the seal 109 is at least partially sandwiched between the base 107 and the bracket 108. The partition 107b abuts against the inner surface of the bracket 108 through the seal 109. In this way, the seal 109 can ensure the sealing between the base 107 and the bracket 108 and the airtightness between the first air intake chamber 102a and the second air intake chamber 102b.

[0048] In one example, the base 107 is provided with a first air inlet 107c and a second air inlet 107d, and the bracket 108 is provided with a first air outlet 108b and a second air outlet 108c.

[0049] The first air inlet 107c connects the air inlet 101a and the first air inlet chamber 102a, and the first air outlet 108b connects the first air inlet chamber 102a and the airflow inlet of the first atomizing component 103a.

[0050] The second air inlet 107d connects to the air inlet 101a and the second air inlet chamber 102b, and the second air outlet 108c connects to the airflow inlet of the second air inlet chamber 102b and the second atomizing component 103b.

[0051] The first air inlet 107c protrudes from the bottom wall of the base 107 at one end of the first air inlet chamber 102a, and the second air inlet 107d protrudes from the bottom wall of the base 107 at one end of the second air inlet chamber 102b. This design prevents the liquid matrix from leaking out through the first air inlet 107c or the second air inlet 107d when it leaks into the first air inlet chamber 102a or the second air inlet chamber 102b.

[0052] In one example, the base 107 is provided with a first wire passage hole 107e, and the bracket 108 is provided with a second wire passage hole 108d; after the base 107 and the bracket 108 are connected, the first wire passage hole 107e and the second wire passage hole 108d are connected.

[0053] The atomizing core of the first atomizing component 103a or the atomizing core of the second atomizing component 103b is electrically connected to one end of the lead wire 103a4. The other end of the lead wire 103a4 passes through the first wire hole 107e and the second wire hole 108d and is electrically connected to the battery cell 105, for example, through the circuit 106.

[0054] After the base 107 is connected to the bracket 108, the first wire passage hole 107e and the second wire passage hole 108d are both separated from the first air intake chamber 102a or the second air intake chamber 102b. Specifically, the sealing member 109 has a third wire passage hole 109a corresponding to the first wire passage hole 107e and the second wire passage hole 108d; after the base 107 is connected to the bracket 108, the sealing member 109 seals the gap between the first wire passage hole 107e and the second wire passage hole 108d, and the lead wire 103a4 can pass through the first wire passage hole 107e, the third wire passage hole 109a and the second wire passage hole 108d in sequence and then be electrically connected to the battery cell 105.

[0055] It is understandable that the aforementioned first wire-passing hole 107e, third wire-passing hole 109a, and second wire-passing hole 108d can be one or more. Generally, there are two first wire-passing holes 107e, third wire-passing hole 109a, and second wire-passing hole 108d, for the positive and negative leads to pass through respectively.

[0056] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
