This application proposes an atomizer for heating and atomizing e-cigarette products of e-liquid. In one embodiment, a common flat atomizer is taken as an example for illustration.

Referring to the structural assembly drawings, cross-sectional views and exploded views of an embodiment of the atomizer shown in Figures 1 to 4, the overall shape is generally flat, including the length direction, width direction, and thickness direction perpendicular to each other in the three-dimensional space, In FIGS. 1 and 2, they are represented by the L direction, the W direction, and the T direction indicated by the coordinates, respectively. Wherein, the dimension of the electronic cigarette atomizer along the length direction L is greater than the dimension of the width direction W, and the dimension of the width direction W is greater than the dimension of the thickness direction T. Among them, according to the requirements of common use, the two ends of the electronic cigarette atomizer along the length direction L are respectively configured as the proximal end 110 and the distal end 120, and the proximal end 110 is configured as the end for installing the mouthpiece cap and inhaling the aerosol. , The distal end 120 is used as one end of the atomizer and the power supply part of the electronic cigarette for assembly connection. In terms of specific components, the electronic cigarette vaporizer includes:

A hollow cylindrical outer casing 10 extending along the length direction L of the atomizer. Based on the above differences, the proximal end 110 of the outer casing 10 is a closed end, and a smoking port A is provided on it for the user to perform a suction operation The distal end 120 of the outer shell 10 is an open design, on which a detachable end cap 20 is installed, and the open structure of the distal end 120 is used to install the necessary functional components of the atomizer inside the outer housing 10. In order to facilitate the subsequent description and the difference in directionality, referring to FIGS. 1 to 3, the outer shell 10 has a first side wall 130 and a second side wall 140 opposite to each other in the thickness direction T.

Further, an oil storage cavity 30 for storing e-liquid and an atomizing assembly 40 for sucking e-liquid from the oil storage cavity 30 and heating and atomizing are provided inside the outer casing 10; specifically,

In the schematic cross-sectional structure shown in FIGS. 5 and 6, the outer casing 10 is provided with a smoke transmission pipe 11 arranged in the axial direction, and the space between the outer wall of the smoke transmission pipe 11 and the inner wall of the outer casing 10 is used to form In the oil storage cavity 30 for storing smoke oil.

The atomization assembly 40 is disposed between the oil storage cavity 30 and the end cover 20. See the structure of the atomization assembly 40 shown in FIG. 3, which may include a porous body 41 for sucking e-liquid from the oil storage cavity 30, and A heating element 42 that heats and atomizes the smoke oil sucked in the porous body 41. As shown in Figures 3 to 6, the porous body 41 can be roughly in an embodiment but not limited to a block structure. According to the situation of use, it includes a first side 413 opposite to the first side wall 130, and a The second side portion 414 opposite to the two side walls 140, and the oil suction surface 411 and the atomizing surface 412 opposite along the axial direction of the outer casing 10 are the upper and lower surfaces of the block porous body 41 in FIG. 3; The oil suction surface 411 is opposite to the oil storage cavity 30, and is directly or indirectly in contact with the e-liquid in the oil storage cavity 30, thereby sucking the e-liquid; the porous pores in the porous body 41 then conduct the e-liquid to the atomizing surface 412 The heated atomization forms an aerosol and releases and escapes from the atomization surface 412. The space between the atomizing surface 412 and the end cap 20 forms an atomizing cavity 60 for aerosol to be released and mixed with air.

In the structure of the porous body 41 shown in FIG. 3, since the oil suction surface 411 and the atomization surface 412 are parallel to each other, the moving directions of the e-liquid and aerosol in the porous body 41 are perpendicular to the plane where the atomization surface 412 is located. The movement of aerosol and e-liquid in the porous body 41 will be smoother, and the manufacturing will be more convenient. In some embodiments, the porous body 41 may be made of hard capillary structures such as porous ceramics, porous glass ceramics, and porous glass. The heating element 42 is preferably formed on the atomized surface 412 by mixing a conductive raw material powder and a printing auxiliary agent into a paste and then sintering after printing, so that all or most of its surface is in contact with the atomizing surface 412. Closely combined, it has the effects of high atomization efficiency, low heat loss, anti-dry burning or greatly reducing dry burning. In some embodiments, the heating element 42 can be made of stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, metallic titanium, and the like.

Further referring to Figures 3 to 6, in order to facilitate the installation and fixation of the atomization assembly 40 and the sealing of the oil storage cavity 30, a sealing assembly 50 is also provided in the outer shell 10, and the sealing assembly 50 includes a silicone sleeve 51 and a support sleeve 52 and the silicone seat 53 not only seal the port of the oil storage cavity 30, but also fix and keep the atomization assembly 40 inside. among them,

The silicone seat 53 is disposed at the end of the oil storage cavity 30 toward the distal end 120, and its shape is adapted to the cross-section of the inner contour of the outer casing 10, so as to seal the oil storage cavity 30 and prevent e-liquid from leaking from the oil storage cavity 30. Further, in order to prevent the shrinkage deformation of the flexible material of the silicone seat 53 from affecting the tightness of the seal, a rigid material support sleeve 52 is provided inside the silicone seat 53, and the filling of the rigid material is used to suppress the shrinkage deformation of the silicone seat 53 and ensure the silicone seat 53 Tightly seal the oil storage cavity 30. At the same time, in order to prevent the atomization assembly 40 from being directly held in the support sleeve 52 of the rigid structure, it cannot be tightly joined and causes a gap to cause oil leakage and other problems. A silicone sleeve 51 made of a flexible material is further sleeved outside the atomization assembly 40, and then set at In the support sleeve 52.

3 and 4 for the specific structure and shape, the silicone sleeve 51 is generally sleeve-shaped, and the internal space is used for accommodating the atomization assembly 40 and is sleeved outside the atomization assembly 40 in a flexible and tight fitting manner.

In some embodiments, the support sleeve 52 may include a main body portion 521 having a substantially elliptical column shape, and an annular portion 522 extending from the main body portion 521 toward the distal end 120. A space in the annular portion 522 is formed to accommodate the silicone sleeve 51 And the holding cavity 523 of the atomization assembly 40. Two first oil guide holes 5211 and one air guide hole 5212 are formed on the main body 521.

Further, the main body 521 is also provided with a first air passage 5213 communicating with the air guide hole 5212; one end of the first air passage 5213 penetrates to communicate with the air guide hole 5212, and the other end is located on the surface of the main body 521 opposite to the first side wall 130 on.

In order to ensure that after the atomization assembly 40 is covered by the silicone sleeve 51, the generated aerosol can smoothly enter the first air passage 5213, a gap 511 is provided at the position of the silicone sleeve 51 relative to the first air passage 5213, and the silicone sleeve 51 and the support After the sleeve 52 is assembled, the notch 511 communicates with the first air passage 5213, so that the aerosol generated by the atomization assembly 40 in the holding cavity 523 is output to the first air passage 5213 through the notch 511.

The silicone seat 53 has two opposite second clamping walls 531 extending downward from the bottom surface, and a receiving cavity 532 for receiving the main body portion 521 of the support sleeve 52 is formed between the two second clamping walls 531. At the same time, two second oil guide holes 533 and an insertion hole 534 for inserting the flue gas transmission tube 11 are formed on the silicone seat 53; the two second oil guide holes 533 and the two on the support sleeve 52 The first oil guide hole 5211 corresponds to the insertion hole 534 and the air guide hole 5212 on the support sleeve 52. In addition, the two second oil guide holes 533 face the oil storage cavity 30 and are used to communicate with the oil storage cavity 30 to conduct smoke oil; the plug hole 534 is connected with the smoke transmission pipe 11. In the preferred mode of FIG. 5, the first end of the smoke transmission tube 11 relative to the proximal end 110 is in communication with the smoking port A, and the second end of the opposite distal end 120 adopts the lower end of the smoke transmission tube 11 to be directly inserted into the insertion hole. Inside 534, air communication is formed.

5, after the sealing assembly 50 is assembled and assembled, the two second oil guide holes 533 on the silicone seat 53 communicate with the two first oil guide holes 5211 of the support sleeve 52 to form a complete smoke oil transmission channel; specifically, smoke The oil conduction is shown by the arrow R1 in Fig. 5, from the oil storage cavity 30 through the second oil guide hole 533 and the first oil guide hole 5211 in sequence, it flows to the oil suction surface 411 of the porous body 41, and then flows on the porous body 41. The inside is conducted to the atomization surface 412 to be atomized. The aerosol transmission process is shown by the arrow R2 in Figures 3 to 7. The aerosol escaping from the atomizing surface 412 passes through the gap 511 of the silicone sleeve 51, the first air passage 5213 of the support sleeve 52, and the air guide hole in turn. 5212 and the insertion hole 534 finally enter the smoke transmission pipe 11 until the smoking port A is smoked, forming a completed aerosol output.

Referring to FIGS. 3 to 6, the end cap 20 is used to cover the distal end 120 of the outer casing 10 to jointly form a closed internal space. The shape and structure of the end cover 20 includes a cover 21, a first support arm 22 standing on the top surface of the cover 21, and a second support arm standing on the top surface of the cover 21 and opposite to the first support arm 22. 23; The first support arm 22 and the second support arm 23 are used to support and fix the sealing assembly 50. After simultaneous installation, the atomization assembly 40 is located between the first support arm 22 and the second support arm 23, so that the atomization surface 412 is opposite to the cover 21, and a certain distance is left to form the atomization cavity 60.

In some embodiments, the cover 21 may be in the shape of a flat plate, and four mounting holes 24 are recessed in the bottom surface for the two magnetic attraction elements 26 and the two electrode columns 27 to be respectively accommodated therein. The magnetic attraction element 26 is used for In order to form a stable mechanical connection, the atomizer of the electronic cigarette and the power supply device are partially magnetically adsorbed. The cover 21 can also be provided with two electrode columns 27 electrically connected to the heating element 42 on the atomizing surface 412 of the porous body 41, and after the atomizer of the electronic cigarette and the power supply device are partially magnetically attracted together, the two The two electrode columns 27 are used to electrically connect the positive and negative electrodes of the power supply device respectively, so as to realize power supply for the heating element 42.

The more important content of the embodiment is that the cover 21 is provided with an air inlet 25 for allowing external air to enter the atomization chamber 60 when the user draws on the smoking port A; the location of the air inlet 25 It is not directly opposite to the atomization surface 412, but is located at the end of the cover 21 close to the second side wall 140 of the outer casing 10, that is, the air inlet 25 and the notch 511 are respectively located in the atomization cavity 60 along the thickness direction of the outer casing 10. The two opposite sides allow the airflow in the atomization cavity 60 to pass through the entire atomization cavity 60 when the user inhales.

At the same time, the heating element 42 is set at the center of the atomization surface 412 during installation, so that the aerosol can be released in the middle of the atomization cavity 60 as much as possible to reduce the diffusion to the corner area; at the same time, the heating element 42 is combined with the inlet The air holes 25 are relatively staggered to prevent the aerosol from being dissipated by the airflow of the intake air and facilitate the concentration of the airflow. And further in a more preferred design, as shown in Figure 7, 3 or more air intake holes 25 can be arranged side by side along the width direction, so that the side-by-side arrangement direction is the same as the atomization extending in the thickness direction. The surface 412, or the direction of the airflow passing through the atomization cavity 60 in the thickness direction is perpendicular; at the same time, the heating element 42 is also extended in the width direction on the atomization surface 42, and the air intake holes 25 can also be arranged as shown in FIG. The span L is preferably greater than the extension length M of the heating element 42, so that the aerosol can be taken away within the range of the airflow.

During the suction process, refer to Fig. 6 for the direction of the airflow path. The outside air enters the atomization cavity 60 through the air inlet 25 near the second side wall 140, penetrates the entire space of the atomization cavity 60, and then passes close to the first The gap 511 of the side wall 130 leads out to the first airway 5213, the air guide hole 5212 and the insertion hole 534, and finally enters the smoke transmission pipe 11 until the smoking port A is smoked. Therefore, the aerosol in the atomization cavity 60 can be taken away as much as possible to reduce the retention, thereby improving the smoke emission efficiency and preventing the formation of condensed oil in the atomization cavity 60.

Based on the variable embodiment of the present application, another shape of the air inlet 25a is shown in FIG. 8. The number of the air inlet 25a on the end cover 20a is one, but the shape is a waist extending in the width direction. Of course, the extended length L is greater than the extended length M of the heating element 42a in the form of a hole or a longitudinal slit.

Based on the same idea as the above-mentioned purpose, in implementation, the air flow in and out of the atomization cavity 60 can also be changed from passing through the atomization cavity 60 along the thickness direction T of the atomizer to passing through the atomization along the width direction W of the atomizer. Chemical cavity 60; specifically in this modified embodiment, the design structure can be seen in Figure 9;

The atomizer includes an outer casing 10b, and a smoke transmission pipe 11b arranged in the axial direction in the outer casing 10b. An oil storage cavity 30b for storing smoke oil is formed between the smoke transmission pipe 11b and the inner wall of the outer casing 10b.

The outer casing 10b is also provided with an end cover 20b, an atomization assembly 40b and a sealing assembly 50b; the porous body of the atomization assembly 40b has an atomization surface 412b opposite to the end cover 20b, and a mist is formed between the atomization surface 412b and the end cover 20b.化cavity 60b.

This embodiment differs from the previous embodiment in that the air inlet 25b is provided on one of the side walls of the outer shell 10b in the width direction, so that the airflow enters from the side of the atomization surface 421b in the width direction, along the figure The manner shown by the arrow R3 penetrates the atomization cavity 60b from the width direction until the atomization surface 412b flows out on the other side in the width direction.

Of course, in this way, the structure of the air flow channel on the sealing assembly 50b needs to be adjusted adaptively. Specifically, on the basis of the previous embodiment, a side wall in the relative thickness direction described in the previous embodiment The notch 511, the first air passage 5213, the air guide hole 5212, etc. are adjusted to be opposite to the side wall in the width direction in FIG. 8, and are respectively located on the opposite sides of the atomization surface 412b in the width direction with the air inlet 25b. In this air flow mode, the technical personnel can refer to the above description for the corresponding changes in the structure of the parts. The technical personnel can make adjustments to ensure that the air flow can generally penetrate the atomization cavity 60, so as to maximize the aerosol in the atomization cavity 60b. Take it away to reduce the retention, thereby improving the efficiency of smoke generation and preventing the formation of condensed oil in the atomization chamber 60b.

The embodiment of the present application further proposes an electronic cigarette product. The structure is shown in FIG. 10, and includes an atomizing device 100 for atomizing e-liquid, and a power supply device 200 for supplying power to the atomizing device 100.
