Summary of the Invention

An atomization cavity is formed in the atomization base, and the heating surface of the heating element is exposed in the atomization cavity. The air duct is connected to the atomization base, and an air outlet channel communicating with the atomization cavity is formed in the air duct. The liquid inlet channel of the atomization base is located on one side of the air duct.

[0010] In a possible design, the air duct is arranged along the central axis inside the main housing.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0040] An existing atomizer of an electronic atomization device includes a shell assembly, an atomization seat and a heating element, etc.; the shell assembly is formed with a liquid storage cavity for storing a liquid atomization matrix; an atomization cavity is formed in the atomization seat, and the heating element is arranged on a side surface of the atomization seat away from the atomization cavity and is used to atomize the liquid atomization matrix entering therein to form an aerosol that can be consumed by a smoker; a liquid inlet channel is opened on the atomization seat, and the liquid atomization matrix in the liquid storage cavity can flow to the heating element through the liquid inlet channel.

[0041] However, some current atomizers are designed to be smaller and smaller for users to carry around, resulting in a smaller overall structural size of the atomizer. As a result, the liquid inlet channel on the atomizer seat is limited by the internal structure and is too narrow, resulting in poor flow of the liquid atomization matrix in the liquid inlet channel and slow liquid delivery. In addition, bubbles are easily generated in the liquid inlet channel during the ventilation process of the atomizer. If the liquid inlet channel is too narrow, the bubbles are easily retained in the liquid inlet channel, hindering the liquid atomization matrix from flowing to the heating element, resulting in insufficient liquid supply and even the phenomenon of dry burning of the heating element producing a burnt smell.

[0042] Based on this, to solve the above problems, the present application designs an atomizer. The length of the liquid inlet channel in the first direction is set to be greater than the maximum length of the heating element in the first direction, so that the atomizer can supply liquid normally. And the length of the liquid inlet channel in the first direction is set to be less than or equal to 7 mm, so that the length of the liquid inlet channel is designed to be short, which can reduce the flow path of the liquid atomization matrix in the liquid inlet channel, reduce the resistance, and increase the flow rate of the liquid atomization matrix in the liquid inlet channel, thus solving the problem of poor liquid supply. Moreover, the short design of the length of the liquid inlet channel can also further avoid excessive bubbles staying in the liquid inlet channel and avoid the problem of insufficient liquid supply caused by the blockage of the liquid inlet channel due to bubble retention.

[0043] Please refer to Figure 1 , the first aspect of the embodiment of the present application provides an atomization device, including an atomizer 1 and a power supply component 2; the power supply component 2 is used to supply power to the atomizer 1.

[0044] Specifically, the power supply component 2 is arranged below the atomizer 1. The power supply component 2 includes a power supply battery, and the power supply battery is electrically connected to the heating element 7 by means of internal wiring or a pin connector, etc., which are not limited thereto. The power supply component 2 can effectively supply power to the heating element 7, so that the heating element 7 can heat and atomize the liquid atomization matrix stored in the atomizer 1 to generate atomized gas for the user to inhale.

[0045] In one embodiment, refer to Figures 1-3 , the atomizer 1 includes a housing component 3 and an atomization base 6 arranged in the housing component 3. The housing component 3 forms a liquid storage cavity 4 and an air outlet channel 5. A heating element 7 is installed on the atomization base 6, and the atomization base 6 forms a liquid inlet channel 8 communicating between the liquid storage cavity 4 and the heating element 7. The length of the liquid inlet channel 8 in the first direction X is greater than the maximum length of the heating element 7 in the first direction X, and the length of the liquid inlet channel 8 in the first direction X is less than or equal to 7 mm. The first direction X is the extending direction of the liquid inlet channel 8.

[0046] It can be understood that the liquid storage cavity 4 of the housing component 3 is used to store the liquid atomization matrix. The liquid atomization matrix can flow to the heating element 7 through the liquid inlet channel 8 arranged in the atomization base 6. The heating element 7 has a heating surface 701 and a liquid absorption surface 702 arranged opposite to each other. An atomization cavity 9 is also formed in the atomization base 6. The heating element 7 is arranged such that its liquid absorption surface 702 faces the liquid inlet channel 8 and the heating surface 701 faces the atomization cavity 9. The liquid atomization matrix in the liquid inlet channel 8 contacts the heating element 7, and the liquid atomization matrix can be conducted to the heating surface 701 through the liquid absorption surface 702 of the heating element 7, and then be atomized under the heating action of the heating surface 701. The heating element 7 releases the generated atomized gas into the atomization cavity 9 of the atomization base 6. The air outlet channel 5 is communicated with the atomization cavity 9, and the atomized gas can reach the user's mouth through the atomization cavity 9 and the air outlet channel 5.

[0047] In some embodiments, the first direction X is the X direction shown in the figure, and the first direction X is the extending direction of the liquid inlet channel 8; specifically, the extending direction of the liquid inlet channel 8 is parallel to any one of the extending direction of the air outlet channel 5, the heating surface 701, and the axial direction of the atomizer 1; the length of the liquid inlet channel 8 in the first direction X is the marked length H shown in the figure.

[0048] Specifically, the heating element 7 is installed in the atomizing seat 6, the liquid inlet channel 8 is formed on one side of the heating element 7, the bottom end of the heating element 7 is not lower than the bottom end of the liquid inlet channel 8 in the first direction X, and the liquid atomization matrix can flow to the heating element 7 well under the action of its own gravity. The length of the liquid inlet channel 8 in the first direction X is greater than the maximum length of the heating element 7 in the first direction X, so that the liquid atomization matrix in the liquid inlet channel 8 can completely cover the liquid absorption surface 702 of the heating element 7, and the liquid atomization matrix can be conducted from the liquid absorption surface 702 of the heating element 7 to the heating surface 701 more evenly, avoiding local dry burning of the heating element 7 and generating a burnt smell.

[0049] Moreover, the length of the liquid inlet channel 8 in the first direction X is set to be less than or equal to 7 mm, that is, the maximum length of the liquid inlet channel 8 is limited to ensure that the length of the liquid inlet channel 8 is in a relatively short range.

[0050] It can be understood that the existing atomizing seat 6 of the atomizer 1 has dimensional requirements because it needs to form an atomization chamber 9 inside, install the heating element 7, and conduct with the air outlet channel 5, and the maximum length of the atomizing seat 6 in the first direction exceeds 10 mm; thus, when the liquid inlet channel 8 is opened in the atomizing seat 6 along the first direction X, the length of the liquid inlet channel 8 is easily more than 7 mm. However, for some currently designed atomizers 1 with relatively small volume sizes, the liquid inlet channels 8 of such atomizers 1 are relatively narrow, resulting in an increase in the flow resistance of the liquid atomization matrix in the liquid inlet channel 8, making the liquid atomization matrix flow slowly; and if the length of the liquid inlet channel 8 is still more than 7 mm, the liquid inlet channel 8 will be narrow and long, which greatly affects the flow of the liquid atomization matrix therein, resulting in poor liquid supply.

[0051] In this application, the length of the liquid inlet channel 8 in the first direction X is set to be less than or equal to 7 mm, that is, the length of the liquid inlet channel 8 is designed to be relatively short, which can reduce the flow path of the liquid atomization matrix in the liquid inlet channel 8, reduce the resistance, and increase the flow rate of the liquid atomization matrix in the liquid inlet channel 8, solving the problem of insufficient liquid supply.

[0052] In some embodiments, the heating element 7 is a porous liquid-absorbing ceramic, which can form a capillary action on the liquid atomization matrix. It can be understood that during the suction and ventilation process of the atomizer 1, bubbles are likely to be generated on the liquid-absorbing surface 702 of the heating element 7. The bubbles staying in the liquid inlet channel 8 will hinder the liquid atomization matrix from entering the heating element 7; especially when the liquid inlet channel 8 is too narrow, more bubbles will stay and block the liquid inlet channel 8, resulting in insufficient liquid supply and dry burning of the heating element 7; a longer liquid inlet channel 8 is more likely to retain more bubbles, posing a greater hidden danger.

[0053] For the atomizer of the present application, first, the length of the liquid inlet channel 8 in the first direction is set to be greater than the maximum length of the heating element 7 in the first direction X, so that the atomizer 1 can supply liquid normally; then, to solve the above problems of insufficient liquid supply and bubble jamming, the length of the liquid inlet channel 8 in the first direction X is set to be less than or equal to 7 mm, so that the length of the liquid inlet channel 8 is designed to be shorter, which can reduce the flow path of the liquid atomization matrix in the liquid inlet channel 8, reduce the flow resistance, and increase the flow rate of the liquid atomization matrix in the liquid inlet channel 8, thus solving the problem of poor liquid flow. Moreover, the shorter design of the length of the liquid inlet channel 8 can also further prevent too many bubbles from staying in the liquid inlet channel 8, avoiding the problem of insufficient liquid supply caused by bubble retention and blockage of the liquid inlet channel 8.

[0054] Refer to Figure 4 , in some embodiments, the cross-sectional area of the liquid inlet channel 8 in the first plane e is less than or equal to 5 mm 2 ; the first plane e is perpendicular to the first direction X.

[0055] Figure 4 As shown in the cross-sectional view of the atomization seat 6 in the first plane e, the atomizer 1 of the embodiment of the present application is specifically a small-sized atomizer 1. Due to the limitation of the structural size, the liquid inlet channel 8 can only be designed to be narrow. Specifically, the area of the cross-section of the liquid inlet channel 8 in the first plane e does not exceed 5 mm 2 .

[0056] Refer to Figure 4 , Figure 5 , in some embodiments, the cross-section of the liquid inlet channel 8 in the first plane e has a cross-sectional edge line 10. A circle is drawn with the geometric center of the cross-section of the liquid inlet channel 8 as the center, and the circle is tangent to the cross-sectional edge line. Among several circles, the diameter b of the smallest circle is greater than or equal to 1.6 mm.

[0057] Specifically, the cross-section of the liquid inlet channel 8 in the first plane e has a cross-sectional edge line 10 in the form of a closed line, and the shape of the cross-sectional edge line 10 is an irregular figure; a circle is drawn with the geometric center of the cross-sectional edge line 10 as the center, and the circle is tangent to the cross-sectional edge line 10. The radius of the drawn circle is the distance between the geometric center of the cross-sectional edge line 10 and any side of the cross-sectional edge line 10.

[0058] Refer to Figure 5 , in some embodiments, the cross-sectional edge line 10 has 4 side lines. By drawing circles in the above manner, two circles can be drawn, and the maximum circle diameter a and the minimum circle diameter b can be obtained; the minimum circle diameter b is the marked length b in the figure, and the maximum circle diameter a is the marked length a in the figure.

[0059] It can be understood that if the value of the minimum circle diameter b is very small, it will make the liquid inlet channel 8 flat and narrow in a certain direction in the first plane e, thus affecting the liquid flow; therefore, when the cross-sectional area of the liquid inlet channel 8 in the first plane e does not exceed 5 mm 2 , by limiting the minimum circle diameter b of the drawn circle to be greater than or equal to 1.6 mm, the gap between the maximum circle diameter a and the minimum circle diameter b will not be too large; to avoid the liquid inlet channel 8 being too flat and narrow in a certain direction in the first plane e and affecting the liquid inlet.

[0060] In some embodiments, the cross-sectional area range of the liquid inlet channel 8 is 2.6 - 5 mm 2 , specifically, the cross-sectional area of the liquid inlet channel 8 can be 3 mm 2 , 4 mm 2 , 4.5 mm 2 , 5 mm 2 .

[0061] Refer to Figure 2 , Figure 3 , in some embodiments, the housing assembly 3 includes a main housing 301 and an air guide tube 302. The main housing 301 is sleeved outside the air guide tube 302. The main housing 301, the air guide tube 302 and the atomizing seat 6 enclose a liquid storage cavity 4; an atomizing cavity 9 is formed in the atomizing seat 6, and the heating surface 701 of the heating element 7 is exposed in the atomizing cavity 9; the air guide tube 302 is connected to the atomizing seat 6 and an air outlet channel 5 communicating with the atomizing cavity 9 is formed in the air guide tube 302; the liquid inlet channel 8 of the atomizing seat 6 is located on one side of the air guide tube 302.

[0062] It can be understood that the atomizing seat 6 is located at the bottom end of the liquid storage cavity 4, and the liquid storage cavity 4 is formed between the air guide tube 302 and the main housing 301. In order to facilitate the liquid flow, the liquid inlet channel 8 needs to be arranged on one side of the air guide tube 302. Therefore, the space reserved for the liquid inlet channel 8 inside the atomizer 1 is limited, and the liquid inlet channel 8 inevitably needs to be designed to be relatively narrow.

[0063] In some embodiments, the air guide tube 302 is arranged along the central axis inside the main housing 301.

[0064] That is, the air duct 302 is located at the geometric center inside the main housing 301. Therefore, the space occupied by the liquid inlet channel 8 in the first plane e is less than half of the space of the atomizer 1 in the first plane e, making the structural design of the liquid inlet channel 8 very limited, resulting in the problem that the liquid inlet channel 8 is too narrow and the liquid flow is blocked.

[0065] Refer to Figure 6 、 Figure 7 、 Figure 8 In some embodiments, the atomization base 6 includes an atomization base main body 11 and a socket 12 provided at the top end of the atomization base main body 11 and protruding upward relative to the atomization base main body 11; a liquid outlet 13 is formed on the top surface of the atomization base main body 11 to communicate the liquid inlet channel 8 with the liquid storage cavity 4; the socket 12 is used for plugging and matching with the air duct 302.

[0066] It can be understood that in the prior art, a groove is directly provided at the top end of the atomization base 6 for plugging and connecting with the air duct 302, and the height of the liquid outlet 13 is flush with the top end of the atomization base 6. If it is necessary to shorten the length of the liquid inlet channel 8, only the overall length of the atomization base 6 can be shortened; however, shortening the overall length of the atomization base 6 will cause the atomization base 6 to be unable to meet the connection with the air duct 302, affecting the structural stability.

[0067] In this application, by providing an upwardly protruding socket 12 at the top end of the atomization base main body 11, plugging and connecting the socket 12 with the air duct 302, and opening a liquid outlet 13 on the top surface of the atomization base main body 11; then, the length of the liquid inlet channel 8 can be shortened by shortening the length of the atomization base main body 11, and the corresponding structural compensation can be carried out by extending the height of the socket 12. While not affecting the cooperation between the structure of the atomization base 6 and the internal structure of the atomizer 1, the top end of the atomization base 6 is designed as a structure with a height difference to achieve the purpose of shortening the length of the liquid inlet channel 8, and the design is ingenious.

[0068] In some embodiments, the height by which the socket 12 protrudes upward from the atomization base main body 11 ranges from 1.5 mm to 2 mm.

[0069] Refer to Figure 3 In some embodiments, the length by which the air duct 302 extends into the socket 12 is greater than or equal to 2 mm.

[0070] It can be understood that in order to make the connection between the socket 12 and the air duct 302 stable, the length by which the bottom end of the air duct 302 extends into the socket 12 is the length h marked in the figure, and h is greater than or equal to 2 mm to ensure that the socket 12 can stably fix the air duct 302.

[0071] Refer to Figure 6 、 Figure 7, the atomizer 1 further includes a seal 14 connected to the top of the atomization base 6. The seal 14 includes a first seal portion 1401 provided at the top of the socket 12 and a second seal portion 1402 provided at the top of the liquid outlet 13 of the atomization base body 11; the height of the second seal portion 1402 in the first direction X is lower than the height of the first seal portion 1401, and an opening 16 communicating with the liquid outlet 13 is formed on the second seal portion 1402, and a socket 17 for inserting the air duct 302 is formed on the first seal portion 1401.

[0072] It can be understood that the seal 14 is provided at the top of the atomization base 6, and the outer peripheral wall of the seal 14 elastically abuts against the inner wall of the main housing 301, so that the seal 14 can effectively seal the bottom end of the liquid storage cavity 4.

[0073] The seal 14 correspondingly forms a high-low structure design. The first seal portion 1401 is located at the top of the socket 12 and is used for sealing connection with the air duct 302; the second seal portion 1402 is located at the top of the liquid outlet 13, and an opening 16 is provided on the second seal portion 1402, and the liquid atomization matrix can enter the liquid outlet 13 from the liquid storage cavity 4 through the opening 16; the second seal portion 1402 is designed to be lower than the first seal portion 1401 to prevent the second seal portion 1402 located at the top of the liquid inlet channel 8 from extending the liquid inlet channel 8.

[0074] Specifically, the atomization base 6 further includes a peripheral portion 15 surrounding the outer edge of the atomization base body 11. The outer edge of the first seal portion 1401 is connected to the top of the peripheral portion 15, so that the seal 14 can effectively isolate the atomization base 6 from the liquid storage cavity 4; and the peripheral portion 15 is in a non-closed shape, and the two ends of the peripheral portion 15 are respectively located on both sides of the liquid outlet 13, and a notch is formed in the peripheral portion 15, and the second seal portion 1402 can be installed in the notch formed in the peripheral portion 15 to prevent the peripheral portion 15 from interfering with the structure of the second seal portion 1402.

[0075] Refer to Figure 7 、 Figure 8 , in some embodiments, a groove 18 surrounding the socket 17 is recessed at the top of the first seal portion 1401, and the groove 18 communicates with the opening 16 of the second seal portion 1402.

[0076] It can be understood that a groove 18 is formed on the first seal portion 1401, and the liquid atomization matrix can be stored in the groove 18, which can improve the liquid storage capacity of the liquid storage cavity 4 as much as possible; and the groove 18 communicates with the opening 16, so that the liquid atomization matrix located in the groove 18 can flow into the opening 16 to enter the liquid inlet channel 8.

[0077] Refer to Figure 8 , in some embodiments, the height of the end of the groove 18 far from the opening 16 is higher than the height of the end of the groove 18 close to the opening 16.

[0078] Understandably, the groove 18 has a height difference, so that the groove 18 can guide the liquid atomization matrix at the bottom of the liquid storage cavity 4 to flow centrally towards the opening 16 under the action of gravity, guide the liquid atomization matrix to flow into the liquid inlet channel 8, and make the liquid supply smooth.

[0079] Refer to Figure 2 、 Figure 3 , in some embodiments, the extending directions of the heating surface 701, the air outlet channel 5, and the liquid inlet channel 8 are substantially parallel to each other.

[0080] Specifically, the extending directions of the heating surface 701, the air outlet channel 5, and the liquid inlet channel 8 are all parallel to the axial direction of the atomizer 1. That is, the heating surface 701 of the heating element 7 is parallel to the first direction X. The direction in which the heating element 7 releases the aerosol into the atomization cavity 9 is perpendicular to the air flow direction in the air outlet channel 5, so that the air flow can better carry the aerosol out of the atomization cavity 9, improve the internal air flow velocity, and increase the atomization amount of the atomizer 1.

[0081] Here, the substantially parallel arrangement specifically means that the heating surface 701 is parallel or inclined relative to the first direction X; and when the heating surface 701 is inclined to the first direction X, the included angle between the heating surface 701 and the first direction X does not exceed 15°, so that the heating surface 701 tends to be parallel to the first direction X.

[0082] In some embodiments, the maximum length of the heating element 7 in the first direction X is the length of the longest side of the heating surface 701, and the length range of the longest side of the heating surface 701 is 2-5 mm.

[0083] Specifically, the heating surface 701 is arranged laterally, that is, the maximum length of the heating element 7 in the first direction X is the length of the long side of the heating surface 701, and the length of the long side of the heating surface 701 is preferably 3 mm; that is, the length range of the liquid inlet channel 8 of the present application in the first direction X is 3-7 mm, ensuring that the length of the liquid inlet channel 8 is a relatively small value, so that the liquid atomization matrix in the liquid storage cavity 4 can flow smoothly through the liquid inlet channel 8 to the heating element 7.

[0084] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
