Description

Technical Field

[0001] The embodiments of the present application relate to the field of electronic atomization technology, and in particular, to an electronic atomization device. Background Art

[0002] Smoking articles (eg, cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. People have attempted to replace these tobacco-burning articles by creating products that release compounds without combustion.

[0003] An example of such a product is a heating device that releases a compound by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there are aerosol providing products, such as so-called electronic atomization devices. These devices typically contain a liquid that is heated to vaporize it, thereby producing an inhalable aerosol. In known electronic atomization devices, a light source is typically arranged at a remote location to prompt the user to inhale. Summary of the invention

[0146] In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific implementation methods.

[0147] The present application proposes an electronic atomization device for atomizing a liquid matrix to generate an aerosol.

[0148] Figure 1 and Figure 2A schematic diagram of an electronic atomization device 100 of one embodiment is shown, including several components disposed within an outer body or housing (which may be referred to as a housing). The overall design of the outer body or housing may vary, and the type or configuration of the outer body that may define the overall size and shape of the electronic atomization device 100 may vary. Typically, the elongated body may be formed by a single integral housing, or the elongated housing may be formed by two or more separable bodies.

[0149] For example, the electronic atomization device 100 can have a control body at one end, which has a shell containing one or more reusable components (e.g., a battery such as a rechargeable battery and / or a rechargeable supercapacitor, and various electronic devices for controlling the operation of the product), and an outer body or housing for suction at the other end.

[0150] In some embodiments, the outer body or housing of the electronic atomization device 100 substantially defines the outer surface of the electronic atomization device 100; Figure 1 to Figure 2 In the specific embodiment shown, the electronic atomization device 100 includes:

[0151] The housing 10 may include one or more reusable components; the housing 10 has a proximal end 110 and a distal end 120 opposite to each other in the longitudinal direction; in use, the proximal end 110 is the end close to the user for suction; the distal end 120 is the end away from the user;

[0152] In some examples, all or only a portion of housing 10 may be formed from a metal or alloy such as stainless steel, aluminum, or other suitable materials including various plastics (eg, polycarbonate), metal-plating over plastic, ceramics, and the like.

[0153] In some embodiments, the housing 10 is formed from several parts. And in some embodiments, the housing 10 is open at the distal end 120. Figures 3 to 7 As shown, the housing 10 comprises:

[0154] The first shell 11 and the second shell 12 ; wherein the first shell 11 is close to or defines a proximal end 110 , and the second shell 12 is close to or defines a distal end 120 .

[0155] according to Figures 3 to 7 As shown, the electronic atomization device 100 also includes:

[0156] The battery cell 70 is used for power supply and is arranged in the second shell 12 .

[0157] exist Figures 3 to 7 In the illustrated embodiment, the electronic atomization device 100 further includes:

[0158] The end cap 20 is combined with and closes the distal end 120 of the housing 10 / second housing 12; the end cap 20 can be removed and disassembled from the distal end 120 of the housing 10 / second housing 12.

[0159] After the distal end 120 of the second shell 12 is removed or disassembled, the distal end 120 of the outer shell 10 is opened or uncovered, so that the battery cell 70 can be taken out or replaced from the distal end 120 of the outer shell 10 / the second shell 12 .

[0160] See also Figures 3 to 7 As shown, the rear end cover 20 at least partially extends from the distal end 120 into the housing 10 / the second shell 12; and an air inlet 21 is arranged on the end cover 20 to allow external air to enter the electronic atomization device 100 after assembly.

[0161] To detachably connect the end cap 20 to the distal end 120 of the housing 10, see Figures 3 to 7 As shown, the electronic atomization device 100 also includes:

[0162] The connecting element 19 is located in the housing 10 and arranged at the distal end 120; the connecting element 19 and the second shell 12 of the housing 10 are tightly connected to each other by riveting or interference fit; in use, the end cap 20 is detachably connected to the connecting element 19, thereby establishing a detachable connection with the housing 10. In an embodiment, the connecting element 19 is made of a rigid alloy such as stainless steel or polymer plastic.

[0163] See also Figures 3 to 7 As shown, the connecting element 19 is basically arranged in an annular shape; a slot 191 for connecting to the end cover 20 is arranged on the connecting element 19; the slot 191 includes a first portion 1911 extending circumferentially, a second portion 1912 extending axially from the first portion 1911 toward the distal end 120; and the second portion 1912 is open toward the distal end 120.

[0164] See also Figures 3 to 7 As shown, the end cover 20 at least partially extends into the interior of the connecting element 19; a latching protrusion 22 is arranged on the end cover 20, and when in use, the latching protrusion 22 extends into the first part 1911 of the latch slot 191 and abuts against the end of the first part 1911 of the latch slot 191; thereby forming a lock to prevent the end cover 20 from being removed or disassembled along the longitudinal direction of the housing 10.

[0165] The operation process of removing the end cap 20 is shown in Figure 7 As shown, the end cover 20 is first rotated around the central axis to move the protrusion 22 from the first part 1911 to the second part 1912, as shown in FIG. Figure 7As shown by the middle arrow P11; after the protrusion 22 moves from the first part 1911 to the second part 1912, the end cover 20 is in an unlocked state, and can be removed from the housing 10 along the longitudinal direction of the electronic atomization device 100. The disassembly operation is as follows: Figure 7 As shown by the middle arrow P12, the end cover 20 is moved longitudinally so that the protrusion 22 leaves the slot 191 along the second portion 1912; thereby releasing the connection between the end cover 20 and the connecting element 19, and the end cover 20 can be disassembled or removed from the distal end 120 of the housing 10.

[0166] After the end cover 20 is removed, the distal end 120 of the housing 10 is opened, so that the battery cell 70 can be taken out or removed from the distal end 120 of the housing 10 by slightly shaking or gently swinging.

[0167] according to Figures 3 to 7 As shown, the electronic atomization device 100 also includes:

[0168] An air outlet 113 for the user to inhale; the air outlet 113 is located at the proximal end 110 of the housing 10 and is defined or formed by the first housing 11;

[0169] A liquid storage chamber 112 for storing a liquid matrix, and an atomizing assembly for drawing a liquid matrix from the liquid storage chamber 112 and heating and atomizing the liquid matrix. To facilitate vaporization and output, the liquid storage chamber 112 and the atomizing assembly are both arranged near the proximal end 110. The electronic atomization device 100 also includes an aerosol output tube 111 arranged in the longitudinal direction, the aerosol output tube 111 at least partially extending in the liquid storage chamber 112, and the liquid storage chamber 112 is formed by the space between the outer wall of the aerosol output tube 111 and the inner surface of the housing 10 / first shell 111. The end of the aerosol output tube 111 relative to the proximal end 110 is connected to the air outlet 113 to output the aerosol generated by the atomization of the atomizing assembly to the air outlet 113 for inhalation.

[0170] according to Figure 3 to Figure 4 As shown in , the aerosol output tube 111 and the housing 10 / the first shell 111 are integrally molded with a moldable material, and the liquid storage cavity 112 formed after the preparation is closed on the side of the proximal end 110 and open on the side facing the distal end 120.

[0171] according to Figures 3 to 12As shown in the figure, a first liquid-conducting element 50 is also provided in the housing 10 / first shell 111. The first liquid-conducting element 50 is a layer of sheet-like or block-like fibers arranged perpendicular to the longitudinal direction of the housing 10 / first shell 111. In some embodiments, the first liquid-conducting element 50 is made of a flexible capillary fiber material, such as natural cotton fibers, non-woven fibers, etc.; specifically, the first liquid-conducting element 50 includes a sheet of liquid-conducting cotton. Or in some other variations, the first liquid-conducting element 50 includes artificial cotton, or hard artificial cotton or artificial foam made of filamentous polyurethane. For example, the first liquid-conducting element 50 uses 138# hard synthetic organic polymer fibers with a viscosity of 0.1 to 0.9 mg / mm 3 The density of the first liquid-conducting element 50 is about 0.04-0.06g when not soaked in liquid. The first liquid-conducting element 50 is made of oriented fibers that are basically oriented along the length direction, width direction or radial direction. The oriented fibers are arranged in the length direction or width direction of the first liquid-conducting element 50, so that the first liquid-conducting element 50 has a strong bending resistance and is hard. Specifically, for example, the first liquid-conducting element 50 is a hard artificial cotton including oriented polyester fibers, or a hard artificial cotton or artificial foam made of filamentous polyurethane.

[0172] See also Figures 3 to 12 As shown, the first liquid-conducting element 50 is accommodated and installed in the bracket 60; after assembly, the first liquid-conducting element 50 and the bracket 60 jointly close the opening of the liquid storage cavity 112 toward the distal end 120; since the bracket 60 is dense, after assembly, the liquid matrix in the liquid storage cavity 112 can basically only be absorbed by the first liquid-conducting element 50 and then leave the liquid storage cavity 112.

[0173] See also Figures 3 to 14 As shown, the upper surface 510 of the first liquid-conducting element 50 adjacent to the liquid storage cavity 112 is in fluid communication with the liquid storage cavity 112, thereby absorbing the liquid matrix. After assembly, the first liquid-conducting element 50 and the bracket 60 together seal and define a portion of the boundary of the liquid storage cavity 112.

In this embodiment, the airflow sensor 15a and the sealing element 16a are arranged perpendicular to the longitudinal direction of the bracket 60a; the airflow sensor 15a is wrapped by the sealing element 16a. Fig.17 and Fig.18 As shown, the retaining element 18a at least partially extends into the third accommodating cavity 631a, and supports the sealing element 16a accommodated and retained in the third accommodating cavity 631a, so that they are stably accommodated and assembled in the third accommodating cavity 631a.

[0271] according to Figures 19 to 20 As shown, the sealing element 16a is provided with air holes 161a for allowing air to pass through the sealing element 16a and enter the third accommodating chamber 631a.

[0272] according to Figures 19 to 20 As shown, an air inlet channel is arranged on the bracket 60a to provide a channel for air to enter the second accommodating chamber 627a. The complete air inlet channel includes:

[0276] During suction, the airflow path is shown in Figures 17 to 20As shown by the middle arrow R2, the external air entering through the air inlet 21a passes through the gap between the battery cell 70a and the outer shell 10a, the retaining element 18a, and then enters the third accommodating chamber 631a through the air hole 161a of the sealing element 16a; then flows into the groove 622a on the surface of the second supporting part 620a through the first channel part 623a, and then flows to the second channel part 625a through the groove 622a; finally, it enters the tubular element 14a from the second channel part 625a, and carries the aerosol generated by the atomization component from the aerosol output tube 111a to the air outlet 113a.

[0277] according to Figures 19 to 20 In the illustrated embodiment, the airflow sensor 15a is used to sense changes in airflow flowing through the bracket 60a and / or the electronic atomization device 100a. And in this embodiment, the airflow sensor 15a has a first sensing surface 151a and a second sensing surface 152a that are opposite to each other in the longitudinal direction of the electronic atomization device 100a. The first sensing surface 151a is arranged toward the proximal end 110a and is connected to the airflow passing through the bracket 60a; the airflow sensor 15a determines the user's suction action and generates a high-level signal when the pressure difference between the first sensing surface 151a and the second sensing surface 152a caused by the suction airflow is greater than a preset threshold. The first sensing surface 151a and the second sensing surface 152a are not wrapped by the flexible sealing element 16a, so as to be exposed for pressure sensing.

[0278] according to Figures 19 to 20 As shown, the support 60a further defines a ventilation channel 670a for providing a flow path for air to enter the liquid storage chamber 112a, so that when the liquid matrix in the liquid storage chamber 112a is gradually consumed so that the negative pressure in the liquid storage chamber 112a is low, air can enter the liquid storage chamber 112a through the ventilation channel 670a to relieve or eliminate the negative pressure in the liquid storage chamber 112a. Specifically, the ventilation channel 670a includes:

[0279] The vent hole 671a radially penetrates from the outer surface of the first support portion 610a to the inner surface of the second section 6112a of the first accommodating cavity 611a;

[0280] The ventilation groove 672a is arranged on the inner surface of the second section 6112a of the first accommodating cavity 611a, and extends from the ventilation hole 671a to the first section 6111a.

[0281] In an embodiment, the vent hole 671a has a diameter of about 0.3 to 2.0 mm; and the vent groove 672a has a width and / or depth of about 0.3 to 2.0 mm. When the negative pressure in the liquid storage chamber 112a exceeds a predetermined threshold, such as Figures 19 to 20As shown by the middle arrow R3, the air enters the liquid storage chamber 112a after passing through the vent hole 671a and the vent groove 672a in sequence, thereby eliminating or relieving the negative pressure in the liquid storage chamber 112a. In order to prevent the entrance of the vent hole 671a from being blocked or blocked by the housing 10a / first shell 11a to maintain smooth air intake, the vent hole 671a is arranged at the entrance of the outer surface of the bracket 60a to have a port 6711a with an enlarged cross-sectional area; the cross-sectional area of ​​the enlarged port 6711a is significantly enlarged, for example, with a width or height of about 3 to 5 mm, which is beneficial to maintaining smooth air intake of the vent hole 671a.

[0282] according to Fig.21 As shown, the airflow sensor 15a is integrated or arranged with a light source, such as Fig.15 As shown in , and configured to emit light in response to the user's suction action; according to Fig.21 As shown by the middle arrow R4, the light emitted by the light source is conducted through the bracket 60a toward the proximal end 110a and / or the liquid storage chamber 112a, and then emitted from the first shell 11a. Therefore, when the user inhales the air outlet 113a during use, the light emitted by the light source can be viewed through the portion of the first shell 11a near the proximal end 110a to determine whether the electronic atomization device 100a responds to the inhalation action and / or whether aerosol is generated according to the inhalation action.

[0283] Or in some other embodiments, the light source is a separate LED light; the light source is not integrated into the airflow sensor 15a. Accordingly, the light source is arranged or accommodated in the third accommodation cavity 631a of the bracket 60a, and is used to respond to the user's suction action and then emit light.
