The heating structure heats the e-liquid stored in the liquid storage member under the electric drive of the power supply device, and the e-liquid is heated to form a smoke. When a user sucks, outside air flows in from the air inlet hole, and after being mixed with the smoke, flows out from the smoking port for the user to suck. However, the electronic cigarettes on the existing market are seriously homogenized. When a user holds the electronic cigarette, the electronic cigarette is prone to slip, affecting the user experience. Summary of the Invention

There are at least two ventilation holes, and at least two of the ventilation holes have different diameters. When the atomizer is connected to the power supply device, at least one of the ventilation holes communicates with the air inlet hole.

[0013] Further, the number of the ventilation holes is two, and the two ventilation holes are symmetrically distributed about the axis of the power supply device.

[0014] The beneficial effect of the present invention is that the present invention discloses an electronic cigarette.

[0045] Specific embodiments

[0046] The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, so it only shows the components related to the present invention.

[0047] Embodiment 1

[0048] Please refer to Figures 1 - 5 , Embodiment 1 of the present invention provides an electronic cigarette 100, which includes an atomizer 10, a power supply device 20 electrically connected to the atomizer 10, and a sensor 30 installed in the power supply device 20. When the user performs a suction operation, after the sensor 30 senses a change in air pressure, the power supply device 20 starts to supply power to the atomizer 10, so that the atomizer 10 works to atomize the e-liquid to generate smoke, and the smoke is mixed with the air flowing in from below the atomizer 10 for the user to inhale.

[0049] Please refer to Figures 2 - 3, the electronic cigarette 100 includes a relatively proximal end surface 103 and a distal end surface 104, with a side surface connecting the proximal end surface 103 and the distal end surface 104, and a smoking port 1321 is provided on the proximal end surface 103. In one embodiment, the side surface includes a holding portion 300, which is enclosed by a first surface 60, a second surface 70, a third surface 80, and a fourth surface 90. Among them, when taking any cross-section along the axial direction of the electronic cigarette 100 on the holding portion 300, the cross-section line segments of the first surface 60 and the second surface 70 on the cross-section are centrosymmetric about the axis center of the electronic cigarette 100, and the cross-section line segments of the third surface 80 and the fourth surface 90 on the cross-section are centrosymmetrically distributed about the axis center of the electronic cigarette 100. Optionally, when taking any cross-section along the axial direction of the electronic cigarette 100 on the holding portion 300, the connection line between the midpoints of the cross-section line segments of the first surface 60 on the cross-section and the midpoints of the cross-section line segments of the second surface 70 on the cross-section is perpendicular to the connection line between the midpoints of the cross-section line segments of the third surface 80 on the cross-section and the midpoints of the cross-section line segments of the fourth surface 90 on the cross-section. Optionally, when taking any cross-section along the axial direction of the electronic cigarette 100 on the electronic cigarette 100, the lengths of the cross-section line segments of the first surface 50 and the second surface 70 on the cross-section are both greater than the lengths of the cross-section line segments of the third surface 80 and the fourth surface 90 on the cross-section. Therefore, the surface areas of the first surface 60 and the second surface 70 are both greater than the surface areas of the third surface 80 and the fourth surface 90. Optionally, there is an arc transition between any adjacent first surface 60, second surface 70, third surface 80, and fourth surface 90. Optionally, the first surface 60 and the second surface 70 are both arc surfaces, and the third surface 80 and the fourth surface 90 are both flat surfaces. Optionally, the radian of the arc surface is relatively gentle and close to a flat surface. In this embodiment, both the proximal end surface 103 and the distal end surface 104 are flat surfaces.

[0050] When the electronic cigarette 100 is placed on a flat surface such as a tabletop, it contacts the flat surface through the first surface 60 or the second surface 70, so that the whole electronic cigarette 100 will not roll over, improving the use stability of the electronic cigarette 100. When the user holds the electronic cigarette 100, the user places the fingers 200 on the first surface 60, the second surface 70, the third surface 80, and the fourth surface 90 in sequence to prevent the electronic cigarette 100 from falling, improving the stability when the user holds the electronic cigarette 100. Specifically, please refer to Figure 2, the finger 200 includes a proximal phalanx 201, a middle phalanx 202 and a distal phalanx 203. The palm and the proximal phalanx 201 are connected by a metacarpophalangeal joint 204. The proximal phalanx 201 and the middle phalanx 202 are connected by a proximal interphalangeal joint 205. The middle phalanx 202 and the distal phalanx 203 are connected by a distal interphalangeal joint 206. When the finger 200 is in a bent and gripping state, the palm, the proximal phalanx 201, the middle phalanx 202 and the distal phalanx 203 enclose a receiving space. When the user grips the electronic cigarette 100, the electronic cigarette 100 is located within the receiving space. The length of the proximal phalanx 201 is greater than the length of the middle phalanx 202. Therefore, the shortest distance from the middle phalanx 202 to the palm is greater than the shortest distance from the proximal phalanx 201 to the distal phalanx 203. Correspondingly, when any cross-section is taken along the axial direction of the electronic cigarette 100 on the electronic cigarette 100, the lengths of the cross-section line segments corresponding to the first surface 50 and the second surface 70 are both greater than the lengths of the cross-section line segments of the third surface 80 and the fourth surface 90. On the one hand, when the user correctly grips the electronic cigarette 100, the first surface 60 is in contact with the proximal phalanx 201, the third surface 80 is in contact with the middle phalanx 202, the second surface 70 is in contact with the distal phalanx 203, and the fourth surface 90 is in contact with the palm, so that the electronic cigarette 100 is in contact with the joints of the finger 200, thereby improving the stability when the user grips the electronic cigarette 100. On the other hand, when the user incorrectly grips the electronic cigarette 100, the electronic cigarette 100 is not in contact with the joints of the finger 200, and the user perceives the non-contact touch through the sense of touch, thereby reminding the user to adjust the gripping direction to correctly grip the electronic cigarette 100. The first surface 60 and the third surface 80 in the shape of an arc surface can guide the gripping direction and enable the user to grip the electronic cigarette 100 more comfortably.

[0051] Specifically, please refer to Figures 6 - 8 , the atomizer 10 includes a liquid storage member 11, a base assembly 12 installed at one end of the liquid storage member 11, an upper cover assembly 13 installed opposite to the base assembly 12 at the other end of the liquid storage member 11, and an air pipe 14 accommodated inside the liquid storage member 11.

[0052] The liquid storage member 11 is generally in a hollow cylindrical structure with an opening at the lower end. The internal space of the liquid storage member 11 forms a liquid storage cavity 111 for storing e-liquid. To facilitate the user's operation of injecting e-liquid into the liquid storage cavity 111, a liquid injection port 112 communicating with the liquid storage cavity 111 is provided on the upper end surface of the liquid storage member 11. It can be understood that the liquid storage member 11 is made of transparent or translucent material so that the user can observe the remaining amount of e-liquid in the liquid storage cavity 111 through the liquid storage member 11, facilitating the user to inject liquid in a timely manner. In this embodiment, the liquid storage member 11 is made of transparent glass. It can be understood that in another embodiment, the liquid storage member 11 is not provided with a liquid injection port 112, but instead, in a pre-packaged manner, the e-liquid is pre-injected into the liquid storage member 11. When the e-liquid is consumed, the entire atomizer 10 is discarded, which is a non-refillable atomizer 10, or, the liquid storage member 11 is discarded separately, which is a non-refillable liquid storage member 11.

[0053] Please refer to Figure 4 , a first induction air passage 101 and an intake passage 102 are provided at intervals in the liquid storage member 11. Specifically, a first induction air passage 101 is axially provided in the wall body of the liquid storage member 11 on one side of the liquid storage cavity 111. The lower end of the first induction air passage 101 penetrates the lower end surface of the liquid storage member 11, and the upper end of the first induction air passage 101 penetrates the upper end surface of the liquid storage member 11.

[0054] In this embodiment, an air outlet hole 113 and an air intake hole 114 are provided on the atomizer 10. Specifically, an air outlet hole 113 is further provided on the upper end surface of the liquid storage member 11, and an air intake hole 114 is provided on the side wall of the liquid storage member 11.

[0055] The base assembly 12 includes an atomization cavity 1241 and a heating structure 125 provided in the atomization cavity 1241. Please refer to Figure 6 , in this embodiment, the base assembly 12 includes a base 121 installed at the lower end of the liquid storage member 11, a support sleeve 122 and a first electrode 123 respectively installed on the base 121, an atomization sleeve 124 sleeved outside the support sleeve 122, and a heating structure 125 installed on the atomization sleeve 124. The heating structure 125 is electrically connected to the first electrode 123.

[0056] In this embodiment, the upper end surface of the base 121 abuts against the lower end surface of the liquid storage member 11. A first communication hole 1011 communicating with the first induction air passage 101 is provided on the base 121 corresponding to the lower opening end of the first induction air passage 101. The first electrode 123 includes two first pole columns (not shown in the figure), and the two first pole columns are installed at the lower end of the base 121.

[0057] Please refer to both Figure 4 and Figure 6, the support sleeve 122 is generally in a cylindrical structure with both ends penetrating. The support sleeve 122 is installed on the upper end face of the base 121. An air inlet 1221 is provided on the side wall of the support sleeve 122. A connection channel (not shown in the figure) is provided on the side wall of the seal 126. When the base assembly 12 and the liquid storage member 11 are installed in place, the air inlet 1221 and the air inlet hole 114 are in alignment and connected through the connection channel. The atomization sleeve 124 is generally in a cylindrical structure with both ends penetrating. The atomization sleeve 124 and the support sleeve 122 enclose a cavity, and this cavity forms the atomization chamber 1241. The air inlet 1221 is connected to the atomization chamber 1241, so that the air inlet hole 114 is connected to the atomization chamber 1241. In this embodiment, the inner cavity where the air inlet hole 114 is connected to the atomization chamber 1241 is the air inlet channel 102. The heating structure 125 includes a heating element (not marked in the figure) and a liquid guiding element (not marked in the figure) that are in contact with each other. The heating element is received in the atomization chamber 1241, and one lead of the heating element is electrically connected to one of the first pole columns, and the other lead of the heating element is electrically connected to the other first pole column. Optionally, a blind hole (not marked in the figure) is provided at the upper end of each first pole column. When the two leads of the heating element are respectively inserted into the two blind holes, each first pole column is radially clamped to deform the blind hole and clamp the leads. The heating element is sleeved outside the liquid guiding element. Both ends of the liquid guiding element pass through the side wall of the atomization sleeve 124 and extend into the liquid storage chamber 111 and are connected to the liquid storage chamber 111. During use, the liquid guiding element absorbs the liquid for smoking from the liquid storage chamber 111, and after the heating element is powered on, it heats the liquid on the liquid guiding element, thereby atomizing the liquid to generate smoke, and the smoke fills the atomization chamber 1241. In this embodiment, the heating element is a columnar spiral heating wire, and the heating element is wrapped around the liquid guiding element. The liquid guiding element is made of cotton. It can be understood that in other embodiments not shown, the heating element can also be a heating cylinder, a heating sheet, etc., which can generate heat after being powered on, and the liquid guiding element can also be made of materials with the ability to absorb liquid, such as fiber ropes, porous ceramics, porous graphite, etc.

[0058] In this embodiment, openings (not marked in the figure) are provided on the upper end face of the support sleeve 122 and the lower end face of the atomization sleeve 124. When the atomization sleeve 124 is sleeved outside the support sleeve 122, the two openings cooperate with each other to form a through hole, and the end of the liquid guiding element passes through the through hole and extends into the liquid storage chamber 111.

[0059] Both of the first pole columns are conductors. Specifically, both of the first pole columns are made of conductive materials such as iron, cobalt, nickel, etc. One of the first pole columns is used as the positive contact, and the other first pole column is used as the negative contact. When the atomizer 10 is installed in place, the power supply device 20 supplies power to the heating element through the two first pole columns.

[0060] In addition, the base assembly 12 further includes a seal 126. The liquid storage chamber 111 is formed by the space enclosed by the liquid storage member 11 and the seal 126. The seal 126 is connected to the base 121 and clamped between the support sleeve 122 and the liquid storage member 11 to play a sealing role and prevent the e-liquid in the liquid storage chamber 111 from leaking.

[0061] The ventilation pipe 14 is generally a tubular structure with both ends penetrating. The ventilation pipe 14 is received in the liquid storage chamber 111. The lower end of the ventilation pipe 14 is connected to the atomization sleeve 124, and the upper end of the ventilation pipe 14 is connected to the liquid storage member 11. The inner cavity of the ventilation pipe 14 is the smoke outlet channel 141, and the smoke outlet channel 141 communicates with the atomization cavity 1241 and the air outlet hole 113. When the user performs a suction operation, the smoke generated in the atomization cavity 1241 enters the user's mouth through the smoke outlet channel 141.

[0062] Please refer to Figure 6 , the upper cover assembly 13 includes a liquid injection plug 131 installed on the liquid injection port 112 and a mouthpiece 132 sleeved on the upper end of the liquid storage member 11.

[0063] The liquid injection plug 131 includes an integrally formed sealing plate 1311 and a sealing column 1312. The sealing plate 1311 covers the upper end surface of the liquid storage member 11. The sealing column 1312 protrudes from the lower end surface of the sealing plate 1311 and is detachably connected to the liquid injection port 112 to seal the liquid injection port 112 and prevent the e-liquid from leaking through the liquid injection port 112. It can be understood that the liquid injection plug 131 is made of a sealing material such as silica gel or rubber. An air flow converging cavity 1313 is formed on the sealing plate 1311, and the air flow converging cavity 1313 communicates with both the air outlet hole 113 and the upper opening end of the first induction air duct 101. In this embodiment, after the user finishes filling the e-liquid into the liquid storage chamber 111 through the liquid injection port 112, the sealing column 1312 is installed in the liquid injection port 112, and the sealing column 1312 can seal the liquid injection port 112 to prevent the e-liquid in the liquid storage chamber 111 from leaking from the liquid injection port 112.

[0064] The mouthpiece 132 is generally a hollow cylindrical structure with an opening at the lower end. The mouthpiece 132 is detachably connected to the liquid storage member 11 by means of clamping, plugging, etc. The liquid injection plug 131 is received in the mouthpiece 132, and the upper end surface of the sealing plate 1311 abuts against the top wall of the mouthpiece 132.

[0065] One of the first card slots 1322 and the first connecting member 1323 is provided on the mouthpiece 132. Correspondingly, the other of the first card slots 1322 and the first connecting member 1323 is provided on the liquid storage member 11. The first card slot 1322 and the first connecting member 1323 cooperate. Specifically, the first card slot 1323 is provided on the side of the mouthpiece 132, and the first connecting member 1323 is provided on the side of the liquid storage member 11. Specifically, the first connecting member 1323 is a buckle. When installing the mouthpiece 132, the first connecting member 1323 is placed in the first card slot 1322 so that the mouthpiece 132 is fixed relative to the liquid storage member 11. Further, when the first connecting member 1323 is placed in the first card slot 1322, the first connecting member 1323 is visible from the outside, which can remind the user that the mouthpiece 132 has been installed in place. In one embodiment, the first connecting member 1323 is an inverted buckle. When the first connecting member 1323 is placed in the first card slot 1322, the mouthpiece 132 is fixed relative to the liquid storage member 11. Further, since the first connecting member 1323 and the first card slot 1322 are not detachable after cooperation, it is impossible to inject liquid after removing the mouthpiece 132.

[0066] A smoking port 1321 is provided at the top of the mouthpiece 132. The smoking port 1321 is communicated with the air flow converging chamber 1313, and further the smoking port 1321 is communicated with the atomization chamber 1241, so that when the user performs a suction operation, the smoke is sucked by the user through the smoking port 1321. Optionally, the smoking port 1321 is provided at the center of the top surface of the mouthpiece 132 and is directly opposite to the smoke outlet channel 141. In addition, in order to improve the airtightness between the mouthpiece 132 and the liquid injection member 11, a sealing ring 133 is clamped between the inner wall of the mouthpiece 132 and the outer wall of the liquid injection member 11 to prevent air leakage. It can be understood that the sealing ring 133 is made of a sealing material such as silica gel or rubber.

[0067] It can be understood that in other embodiments not shown, the liquid injection plug 131 may also only include the sealing column 1312, that is, the sealing plate 1311 and the air flow converging chamber 1313 thereon are omitted, as long as the smoking port 1321 on the mouthpiece 132 is communicated with the air outlet hole 113 and the upper end opening of the first induction air duct 101.

[0068] In addition, the upper cover assembly 13 further includes a mouthpiece sealing plug 134. The mouthpiece sealing plug 134 is detachably installed on the smoking port 1321. When the user uses it, the mouthpiece sealing plug 134 needs to be removed first before performing the suction operation. When the user does not use it, on the one hand, it can prevent bacteria from entering the inside of the electronic cigarette 100 through the smoking port 1321, and at the same time, it can also play a safety protection function for children. It can be understood that the mouthpiece sealing plug 134 is made of a sealing material such as silica gel or rubber.

[0069] Please refer to Figures 8 - 12, the power supply device 20 includes a power supply housing 21, an end cap 22 installed inside one end of the power supply housing 21, a power supply 23 housed inside the power supply housing 21, and a second electrode 24 installed on the end cap 22.

[0070] The power supply housing 21 is generally in the shape of a hollow cylindrical structure with an opening at the upper end. At least part of the upper end of the power supply housing 21 is detachably sleeved outside the atomizer 10. In this embodiment, the power supply housing 21 is snap-connected to the liquid storage member 11. Specifically, one of the second card slots 1324 and the second connecting member 1325 is provided on the liquid storage member 11, and the other of the second card slots 1324 and the second connecting member 1325 is provided on the power supply housing 21. The second connecting member 1325 and the second card slot 1324 cooperate to keep the atomizer 10 fixed relative to the power supply device 20. Specifically, the second card slot 1324 is provided on the side of the liquid storage member 11, and the second connecting member 1325 is provided on the side of the power supply housing 21. Specifically, the second connecting member 1325 is a snap. It can be understood that the number of the second card slots 1324 and the second connecting member 1325 is not limited herein, as long as the atomizer 10 can be kept fixed relative to the power supply device 20. It can be understood that after the liquid storage member 11 and the power supply housing 21 are installed in place, the atomizer 10 and the power supply device 20 are installed in place. It can also be understood that in other embodiments not shown, the atomizer 10 and the power supply device 20 can also be connected through the detachable connection relationship between the base 121 and the end cap 22, for example, by snap connection, magnetic connection, etc. In addition, a ventilation hole 211 is provided on the side wall of the power supply housing 21 corresponding to the air inlet hole 114. After the power supply housing 21 is connected to the atomizer 10, the ventilation hole 211 is aligned and communicated with the air inlet hole 114, facilitating the external gas to enter the atomizer 10 through the ventilation hole 211. The end cap 22 is generally rectangular in shape and is installed inside the power supply housing 21, and the end face of the end cap 22 is perpendicular to the axis of the power supply housing 21. A sealed space formed between the power supply housing 21 and the end cap 22 forms a second induction air passage 201, and the power supply 23 and the sensor 30 are both housed in the second induction air passage 201. The second electrode 24 includes two second pole columns (not marked in the figure). The two second pole columns are installed at the upper end of the end cap 22, and the two second pole columns are respectively electrically connected to the positive and negative electrodes of the power supply 23. The second pole columns correspond to the first pole columns one by one. After the atomizer 10 is connected to the power supply device 20, one of the second pole columns contacts and is electrically connected to one of the first pole columns, and the other second pole column contacts and is electrically connected to the other first pole column, thereby realizing the electrical connection relationship between the heating element of the atomizer 10 and the power supply device 20.

[0071] Optionally, in order to facilitate observing the remaining amount of e-liquid in the liquid storage cavity 311, an observation port 213 communicating with the outside is provided on the outer shell 21. The liquid storage member 11 is exposed to the outside through the observation port 213, and the user can observe the remaining amount of e-liquid in the liquid storage cavity 311 through the observation port 213.

[0072] To facilitate the installation of the power source 23 and the sensor 30, the power supply device 20 further includes a mounting bracket 25 received in the second induction air passage 201. The power source 23 and the sensor 30 are both detachably mounted on the mounting bracket 25. It can be understood that in other embodiments not shown, the mounting bracket 25 can also be omitted. At this time, the power source 23 and the sensor 30 are both detachably mounted on the channel wall of the second induction air passage 201.

[0073] A second communication hole 2011 communicating with the second induction air passage 201 is provided on the end face of the end cap 22. The second communication hole 2011 corresponds to the first communication hole 1011. When the atomizer 10 is connected to the power supply device 20, the first communication hole 1011 communicates with the second communication hole 2011, so that the first induction air passage 101 is connected to the second induction air passage 201. Additionally, please refer to Figure 10 simultaneously. The electronic cigarette 100 of the present invention further includes a control board 40 and a USB (Universal Serial Bus) charging structure (not shown in the figure). The sensor 30 and the USB charging structure are both integrated on the control board 40, with a high degree of integration and facilitating assembly. The control board 40 is electrically connected to both the sensor 30 and the power supply device 20. The charging interface in the USB charging structure passes through the power supply outer shell 21 and extends to the outside. When the charging interface is triggered, the power supply device 20 can be charged through the charging interface. When the user performs a sucking operation, a negative pressure is formed in the first induction air passage 101 and the second induction air passage 201. After the sensor 30 senses the pressure change, a differential pressure signal is generated and transmitted to the control board 40. After receiving the differential pressure signal, the control board 40 controls the power supply device 20 to supply power to the atomizer 10. At this time, the e-liquid is atomized to generate smoke. Meanwhile, external gas sequentially enters the atomization cavity 1241 through the ventilation hole 211, the air inlet hole 114, and the air inlet 1221 and mixes with the smoke to form a mixed flue gas. Under the sucking action, the mixed flue gas finally enters the user's mouth through the ventilation pipe 14 via the smoking port 1321. Figure 9 The direction indicated by the arrow in [] is the air flow direction.

[0074] In this embodiment, the sensor 30 is a differential pressure sensor. Understandably, in other embodiments not shown, the sensor 30 can also be an air flow sensor. Specifically, the power supply device 20 is provided with a ventilation port communicating with the second induction air duct 201. When the user performs a suction operation, the air flow in the second induction air duct 201 passes through the air flow sensor. After the air flow sensor senses the air flow change, an air flow signal is generated. After this air flow signal is transmitted to the control board 40, the control board 40 controls the power supply device 20 to supply power to the atomizer 10.

[0075] Please refer to again Figure 9 , Figure 13 , the electronic cigarette 100 of the present invention further includes a light guiding component 50 housed in the second induction air duct 201. The light guiding component 50 includes a fixing plate 51 mounted on the mounting bracket 25, a light emitting element 52 mounted on the fixing plate 51, a light guiding plate 53 covering the heating element 52, and a light shielding sheet 54 mounted on the fixing plate 51. The part of the light guiding plate 53 covering the light emitting element 52 protrudes, and the protruding part of the light guiding plate 53 passes through the light shielding sheet 54. The light emitting element 52 is electrically connected to the power supply device 20. When the control board 40 controls the power supply device 20 to supply power to the atomizer 10, the control board 40 also controls the power supply device 20 to supply power to the light emitting element 52, so that the light emitting element 52 works and emits light. In this embodiment, the light emitting element 52 is an LED lamp. The light guiding plate 53 is made of silica gel or rubber material, so that the light emitted by the light emitting element 52 is weakened after passing through the light guiding plate 53 and is not dazzling. In addition, the light shielding sheet 54 can prevent light from passing through the side of the light emitting element 52. A light transmission hole 212 is provided on the side wall of the power supply housing 21 corresponding to the light emitting element 52, and the light emitted by the light emitting element 52 can be perceived by the user through the light transmission hole 212. Thus, when the user performs a suction operation, the light emitting element 52 is energized and emits light, which can provide the situation of the user sucking the electronic cigarette 100. At the same time, it can also enhance the playability of the electronic cigarette 100, thereby improving the user experience.

[0076] Please refer to again Figure 9, in this embodiment, there are two second communication holes 2011, and the two second communication holes 2011 are symmetrically distributed about the axis of the end cap 22, that is, the two second communication holes 2011 are symmetrically distributed about the axis of the power supply device 20. When the atomizer 10 is connected to the power supply device 20 at an angle, the first communication hole 1011 is in alignment and communication with one of the second communication holes 2011, and the other second communication hole 2011 is closed by the base 121. At this time, the first induction air passage 101 is in communication with the second induction air passage 201, and the sensor 30 can be triggered to work during the user's suction operation. When the user rotates the atomizer 10 by 180° relative to the power supply device 20 and then connects it to the power supply device 20, the second communication hole 2011 that was initially in communication with the first communication hole 1011 is closed by the base 121, and the second communication hole 2011 that was initially closed by the base 121 is in alignment and communication with the first communication hole 1011. At this time, the first induction air passage 101 is still in communication with the second induction air passage 201, and the sensor 30 can also be triggered to work during the user's suction operation.

[0077] In this embodiment, the number of vent holes 211 is two. The two vent holes 211 are oppositely opened on the side wall of the power supply housing 21, and the two vent holes 211 are symmetrically distributed about the axis of the power supply housing 21, and the apertures of the two vent holes 211 are different. Specifically, both of the two vent holes 211 are close to the upper end of the power supply housing 21.

[0078] When the atomizer 10 is connected to the power supply device 20, the air inlet hole 114 is in alignment and communication with one of the vent holes 211. When the user rotates the atomizer 10 by 180° relative to the power supply device 20 and then connects it to the power supply device 20, the air inlet hole 114 is in alignment and communication with the other vent hole 211.

[0079] The user can adjust the air intake amount of the outside air entering the atomization chamber 1241 by aligning the air inlet hole 114 with any one of the vent holes 211, that is, by aligning the air inlet hole 114 with the vent holes 211 of different apertures, so as to adjust the resistance when the user sucks the smoke, so as to meet the usage requirements and experiences of different users.

[0080] Understandably, in an embodiment not shown, there are multiple second communication holes 2011, and the multiple second communication holes 2011 are all distributed on the same circumference centered on the center of the end cap 22. At this time, by deflecting the atomizer 10 relative to the end cap 22, the first communication hole 1011 can be aligned and communicated with any one of the second communication holes 2011, so that the first induction air passage 101 is communicated with the second induction air passage 201, so as to trigger the sensor 30 to work when the user performs a suction operation. Correspondingly, there are multiple ventilation holes 211, at least two of the ventilation holes 211 have different apertures, and the multiple ventilation holes 211 are all distributed on the same circumference centered on the axis of the power supply housing 21. At this time, by deflecting the atomizer 10 relative to the power supply device 20, the air inlet hole 114 can be communicated with any one of the ventilation holes 211, that is, by communicating the air inlet hole 114 with ventilation holes 211 of different apertures, the intake air volume of the outside air entering the atomization chamber 1241 is adjusted, and further the resistance when the user smokes the smoke is adjusted to meet the usage requirements and experiences of different users.

[0081] In this embodiment, the sensor 30 is installed at the lower end of the mounting bracket 25, and the sensor 30 and the mounting bracket 25 are accommodated in the second induction air passage 201. The sealed space formed between the power supply housing 21 and the end cap 22 forms the second induction air passage 201. Compared with forming the second induction air passage 201 at the upper end of the end cap 22 or the mounting bracket 25, installing the sensor 30 at the lower end of the mounting bracket 25 simplifies the structure of the end cap 22 or the mounting bracket 25, reduces the design difficulty, and reduces the production cost.

[0082] In this embodiment, the upper end surface of the end cap 22 is a flat surface, the second electrode 24 is installed on the upper end of the end cap 22 and protrudes from the upper end surface of the end cap 22, and the second communication hole 2011 is flush with the upper end surface of the end cap 22, which is convenient for any one of the first pole columns to be electrically connected to any one of the second pole columns. When the two second pole columns are respectively electrically connected to the two first pole columns, the circuit is turned on.

[0083] Thus, for the electronic cigarette 100 provided by the present invention, the user can connect the atomizer 10 and the power supply device 20 at multiple angles, and can communicate the first induction air passage 101 with the second induction air passage 201 to trigger the sensor 30 to work. The user operation is more diversified and user-friendly, which facilitates the user to use and improves the user experience. At the same time, by connecting the atomizer 10 and the power supply device 20 at multiple angles, the air inlet hole 114 is communicated with the ventilation holes 211 of different apertures to adjust the intake air volume of the outside air entering the atomization chamber 1241, and further adjust the resistance when the user smokes the smoke to meet the usage requirements and experiences of different users.

[0084] The present invention discloses an electronic cigarette 100. Along any cross-section taken axially of the electronic cigarette 100 on the holding part 300, the cross-sectional line segments of the first surface 60 and the second surface 70 on the cross-section are centrosymmetric about the axis center of the electronic cigarette 100, and the cross-sectional line segments of the third surface 80 and the fourth surface 90 on the cross-section are centrosymmetric about the axis center of the electronic cigarette 100. When a user holds the electronic cigarette 100, the user prevents the electronic cigarette 100 from falling by sequentially placing the fingers 200 on the first surface 60, the second surface 70, the third surface 80, and the fourth surface 90, thereby improving the stability when the user holds the electronic cigarette 100.

[0085] Embodiment 2

[0086] The difference between the electronic cigarette provided in Embodiment 2 of the present invention and the electronic cigarette 100 in Embodiment 1 lies in that: there are two first communication holes 1011 on the base 121, and the two first communication holes 1011 are centrosymmetrically distributed about the axis of the base 121. There is only one second communication hole 2011 on the end cap 22, and it is correspondingly arranged with the first communication hole 1011.

[0087] When the atomizer 10 is connected to the power supply device 20 at an angle, the second communication hole 2011 is in alignment and communication with one of the first communication holes 1011, so that the first induction air passage 101 is in communication with the second induction air passage 201, and the sensor 30 can be triggered to work when the user performs a suction operation. When the user rotates the atomizer 10 by 180° relative to the power supply device 20 and then connects it to the power supply device 20, the second communication hole 2011 is in alignment and communication with the other first communication hole 1211. At this time, the first induction air passage 101 is still in communication with the second induction air passage 201, and the sensor 30 can also be triggered to work when the user performs a suction operation.

[0088] In addition, a sealing gasket is further provided on the upper end surface of the end cap 22. The sealing gasket is centrosymmetrically distributed about the axis of the end cap 22 with respect to the second communication hole 2011. Therefore, when the second communication hole 2011 is in alignment and communication with one of the first communication holes 1011, the sealing gasket closes the other first communication hole 1011, thereby preventing air flow from flowing out of the two first communication holes 1011 simultaneously and affecting the sensitivity of the sensor 30. It can be understood that there are multiple first communication holes 1011. Correspondingly, there are also multiple sealing gaskets, as long as it is satisfied that when the atomizer 10 is installed at different angles, only one first communication hole 1011 is in alignment and communication with the second communication hole 2011.

[0089] Embodiment 3

[0090] The difference between the electronic cigarette provided in the third embodiment of the present invention and the electronic cigarette 100 in the first embodiment lies in that: in this embodiment, there are two first communication holes 1011 on the base 121, and the two first communication holes 1011 are symmetrically distributed about the axis of the base 121. There are two second communication holes 2011 on the end cap 22, and the two second communication holes 2011 are symmetrically distributed about the axis of the end cap 22. Therefore, when the atomizer 10 is connected to the power supply device 20, one first communication hole 1011 is always aligned and communicated with one second communication hole 2011, so that the first induction air passage 101 and the second induction air passage 201 are always kept in communication, so as to trigger the sensor 30 to work when the user performs a suction operation. It can be understood that the number of the first communication holes 1011 and the second communication holes 2011 can both be multiple, as long as it is satisfied that when the atomizer 10 is connected to the power supply device 20, each first communication hole 1011 can be aligned and communicated with a second communication hole 2100. For the arrangement manner of the first communication holes 1011 and the second communication holes 2011, no limitation is made here.

[0091] Embodiment Four

[0092] Please refer to Figures 14 to 17 , the fourth embodiment of the present invention provides an electronic cigarette 100, which includes an atomizer 10, a power supply device 20 electrically connected to the atomizer 10, and a sensor 30 installed in the power supply device 20. When the user performs a suction operation, after the sensor 30 senses a change in air pressure, the power supply device 20 starts to supply power to the atomizer 10, so that the atomizer 10 works to atomize the e-liquid to generate smoke, and the smoke is mixed with the air flowing in from below the atomizer 10 for the user to inhale.

[0093] The atomizer 10 includes a liquid storage member 11, a base assembly 12 installed at one end of the liquid storage member 11, and a ventilation pipe 14 accommodated inside the liquid storage member 11.

[0094] The liquid storage member 11 is generally in a hollow cylindrical structure with an opening at the lower end. The internal space of the liquid storage member 11 forms a liquid storage cavity 111 for storing e-liquid. To facilitate the user to inject e-liquid into the liquid storage cavity 111, a liquid injection port 112 communicating with the liquid storage cavity 111 is provided on the side of the liquid storage member 11. A liquid injection plug 131 is provided in the liquid injection port 112. The liquid injection plug 131 includes an integrally formed sealing plate 1311 and a sealing column 1312. The sealing plate 1311 covers the side of the liquid storage member 11, and the sealing column 1312 protrudes from the sealing plate 1311 and is detachably connected to the liquid injection port 112. When the user finishes injecting e-liquid into the liquid storage cavity 111 through the liquid injection port 112, the sealing column 1312 is installed in the liquid injection port 112, and the sealing column 1312 can seal the liquid injection port 112 to prevent the e-liquid in the liquid storage cavity 111 from leaking from the liquid injection port 112. It can be understood that the liquid injection plug 131 is made of a sealing material such as silica gel or rubber. It can be understood that in another embodiment, the liquid storage member 11 is not provided with a liquid injection port 112, but a pre-packaging method is adopted to pre-inject e-liquid into the liquid storage member 11. When the e-liquid is consumed, the entire atomizer 10 is discarded, which is a non-reusable atomizer 10, or the liquid storage member 11 is discarded separately, which is a non-reusable liquid storage member 11.

[0095] Optionally, the liquid storage member 11 is made of a transparent or semi-transparent material so that the user can observe the remaining amount of e-liquid in the liquid storage cavity 111 through the liquid storage member 11, which is convenient for the user to inject liquid in time. In this embodiment, the liquid storage member 11 is made of transparent glass.

[0096] In this embodiment, the atomizer 10 is provided with an air inlet hole 114 and a smoking port 1321. Specifically, the air inlet hole 114 is provided below the side of the liquid storage member 11, and external air enters the atomizer 10 from the air inlet hole 114. It can be understood that in another embodiment, the air inlet hole 114 can also be provided above the side of the liquid storage member 11. The smoking port 1321 is provided at the top of the liquid storage member 11.

[0097] The base assembly 12 includes an atomization cavity 1241 and a heating structure provided in the atomization cavity 1241. In this embodiment, the base assembly 12 includes a base 121 installed at the lower end of the liquid storage member 11, a first electrode 123 installed on the base 121, and a heating structure (not shown in the figure) electrically connected to the first electrode 123.

[0098] In this embodiment, the upper end surface of the base 121 abuts against the lower end surface of the liquid storage member 11, and the base 121 is provided with a first communication hole 1011 communicating with the outside.

[0099] The first electrode 123 includes two first pole columns (not marked in the figure), and the two first pole columns are installed at the lower end of the base 121.

[0100] The heating structure includes a heating element (not shown in the figure) and a liquid guiding element (not shown in the figure) that are in contact with each other. The liquid guiding element can adsorb the smoke liquid in the liquid storage cavity and conduct it to the heating element, and the heating element can heat and atomize the smoke liquid adsorbed by the liquid guiding element. The space for the heating element to heat and atomize the smoke liquid is the atomization cavity 1241. The atomization cavity 1241 is communicated with the air inlet hole 114 and the first communication hole 1011. The smoke formed by the heating element heating the smoke liquid is mainly located in the atomization cavity 1241. In this embodiment, one pin of the heating element is electrically connected to one of the first pole columns, and the other pin of the heating element is electrically connected to the other first pole column.

[0101] The heating element can be made of materials such as stainless steel, nickel-chromium alloy, and ceramics.

[0102] The liquid guiding element is made of materials such as cotton, cotton cloth, or porous ceramics that are easy to adsorb liquids.

[0103] During use, the liquid guiding element absorbs the smoke from the liquid storage cavity 111. After the heating element is powered on, it heats the smoke liquid on the liquid guiding element, and then atomizes the smoke liquid to generate smoke, which fills the atomization cavity 1241.

[0104] Optionally, the base assembly 12 further includes a sealing member 126 sleeved on the heating structure. The lower end surface of the sealing member 126 is connected to the upper end surface of the base 121. An installation hole (not shown in the figure) for installing the ventilation pipe 14 is opened on the sealing member 126, and the installation hole is communicated with the atomization cavity 1241. The liquid storage cavity 111 is formed by the space surrounded by the liquid storage member 11 and the sealing member 126. The heating mechanism is clamped between the sealing member 126 and the ventilation pipe 14. A part of the liquid guiding element extends into the atomization cavity 1241, and another part of the liquid guiding element extends into the liquid storage cavity 111 to absorb the smoke liquid and conduct the smoke liquid to the part extending into the atomization cavity 1241. An opening (not shown in the figure) corresponding to the first communication hole is opened on the sealing member 126, and the inner cavity of the opening and the first communication hole 1011 together form the first induction air passage 101. In this embodiment, the sealing member 126 is made of materials with good sealing performance such as silica gel or rubber. The side part of the sealing member 126 abuts against the cavity wall of the liquid storage cavity 111. Through the tension fit between the side part of the sealing member 126 and the cavity wall of the liquid storage cavity 111, the gap between the side part of the sealing member 126 and the cavity wall of the liquid storage cavity 111 can be sealed, preventing the smoke liquid in the liquid storage cavity 111 from leaking to the outside through the gap.

[0105] Both of the two first pole columns are conductors. Specifically, both of the two first pole columns are made of conductive materials such as iron, cobalt, and nickel. One of the first pole columns is used as the positive contact, and the other first pole column is used as the negative contact. When the atomizer 10 is installed in place, the power supply device 20 supplies power to the heating element through the two first pole columns.

[0106] The vent pipe 14 is generally a tubular structure with both ends penetrating. The vent pipe 14 is accommodated in the liquid storage cavity 111, and the lower end of the vent pipe 14 is connected to the hole wall of the mounting hole. The upper end of the vent pipe 14 is connected to the liquid storage member 11. The inner cavity of the vent pipe 14 is the smoke outlet channel 141, and the smoke outlet channel 141 communicates with the atomization cavity 1241 and the smoking port 1321. When the user performs a suction operation, the smoke generated in the atomization cavity 1241 enters the user's mouth through the smoke outlet channel 141.

[0107] The power supply device 20 includes a power supply housing 21, an end cover 22 installed inside one end of the power supply housing 21, a power supply 23 accommodated in the power supply housing 21, and a second electrode 24 installed on the end cover 22.

[0108] The power supply housing 21 is generally a hollow cylindrical structure with an opening at the upper end. At least a part of the upper end of the power supply housing 21 is detachably sleeved outside the atomizer 10, so that the power supply housing 21 is detachably connected to the liquid storage member 11. In this embodiment, the power supply housing 21 is snap-connected to the liquid storage member 11. Specifically, the liquid storage member 11 is provided with one of the second card slots 1324 and the second connecting member 1325, and the power supply housing 21 is provided with the other of the second card slots 1324 and the second connecting member 1325. Through the cooperation of the second connecting member 1325 and the second card slot 1324, the atomizer 10 is fixed relative to the power supply device 20. Specifically, the second card slot 1324 is opened on the side of the liquid storage member 11, and the second connecting member 1325 is opened on the side of the power supply housing 21. Specifically, the second connecting member 1325 is a buckle. When installing the power supply device 202, the second connecting member 1325 is placed in the second card slot 1324 to fix the atomizer 10 relative to the power supply device 20.

[0109] A ventilation hole 211 is provided on the side wall of the power supply housing 21 corresponding to the air inlet hole 114. When the power supply housing 21 is connected to the atomizer 10, the ventilation hole 211 is aligned and communicated with the air inlet hole 114, facilitating the external gas to enter the atomizer 10 through the ventilation hole 211. In one embodiment, the number of ventilation holes 211 is two, and the two ventilation holes 211 are oppositely opened on the side wall of the power supply housing 21, and the apertures of the two ventilation holes 211 are different. Specifically, both of the two ventilation holes 211 are close to the upper end of the power supply housing 21. When the atomizer 10 is connected to the power supply device 20, the air inlet hole 114 is aligned and communicated with one of the ventilation holes 211. When the user rotates the atomizer 10 180° relative to the power supply device 20 and then connects it to the power supply device 20, the air inlet hole 114 is aligned and communicated with the other ventilation hole 211. The user can adjust the intake air volume of the outside air entering the atomization cavity 1241 by aligning the air inlet hole 114 with any one of the ventilation holes 211, that is, by aligning the air inlet hole 114 with the ventilation holes 211 of different apertures, so as to adjust the resistance when the user smokes the smoke, so as to meet the usage requirements and experiences of different users.

[0110] Specifically, when the atomizer 10 is connected to the power supply device 20, since the aperture size of the air inlet hole 114 is constant, if the air inlet hole 114 is aligned and communicated with the ventilation hole 211 having a larger aperture, when the user sucks, the suction resistance is small, and the outside air can easily enter the atomization chamber 1241 through the ventilation hole 211, so that more air flows into the atomization chamber 1241. The outside air can be fully mixed with the atomized smoke, improving the suction taste. Moreover, the user can suck the electronic cigarette 100 with a smaller suction force.

[0111] If the air inlet hole 114 is aligned and communicated with the ventilation hole 211 having a smaller aperture, when the user sucks, the suction resistance is large, and the outside air is not easy to enter the atomization chamber 1241 through the ventilation hole 211, so that less air flows into the atomization chamber 1241. At this time, although the outside air can be mixed with the atomized smoke, the smoke flowing out from the smoking port 1321 is thicker. Moreover, the user needs to use a larger suction force to suck the electronic cigarette 100.

[0112] It can be understood that in another embodiment, there are multiple ventilation holes 211 (i.e., three or more), at least two ventilation holes 211 have different aperture sizes, and the multiple ventilation holes 211 are all distributed on the same circumference centered on the center of the power supply housing 21. At this time, by deflecting the atomizer 10 relative to the end cap 22, the air inlet hole 114 can be aligned and communicated with any one of the ventilation holes 211, so that the air inlet hole 114 is communicated with the atomization chamber 1241. By communicating the air inlet hole 114 with the ventilation holes 211 of different aperture sizes, the air intake amount of the outside air entering the atomization chamber 1241 is adjusted, and further the resistance when the user sucks the smoke is adjusted to meet the usage requirements and experiences of different users.

[0113] The end cap 22 is installed in the power supply housing 21, and the end face of the end cap 22 is perpendicular to the axis of the power supply housing 21. The sealed space formed between the power supply housing 21 and the end cap 22 forms a second induction air passage 201, and the power supply 23 and the sensor 30 are both received in the second induction air passage 201.

[0114] The second electrode 24 includes two second pole columns (not shown in the figure). The two second pole columns are installed at the upper end of the end cap 22, and the two second pole columns are respectively electrically connected to the positive and negative electrodes of the power supply 23. The second pole columns correspond to the first pole columns one by one. After the atomizer 10 is connected to the power supply device 20, one of the second pole columns contacts and is electrically connected to one of the first pole columns, and the other second pole column contacts and is electrically connected to the other first pole column, so as to realize the electrical connection relationship between the heating element of the atomizer 10 and the power supply device 20.

[0115] To facilitate the installation of the power source 23 and the sensor 30, the power supply device 20 further includes a mounting bracket 25 housed in the second induction air passage 201. The power source 23 and the sensor 30 are both detachably mounted on the mounting bracket 25. Specifically, the sensor 30 is mounted at the lower end of the mounting bracket 25, simplifying the structure of the end cap 22 or the mounting bracket 25, reducing the design difficulty, and reducing the production cost.

[0116] A second communication hole 2011 communicating with the second induction air passage 201 is formed on the end face of the end cap 22. The second communication hole 2011 corresponds to the first communication hole 1011. When the atomizer 10 is connected to the power supply device 20, the first communication hole 1011 communicates with the second communication hole 2011, so that the atomization chamber 1241 is connected to the second induction air passage 201.

[0117] The electronic cigarette 100 of the present invention further includes a control board (not labeled in the figure) housed in the power supply housing 21. The control board is electrically connected to both the sensor 30 and the power supply device 20. In this embodiment, the sensor 30 is a differential pressure sensor. When the user performs a suction operation, a negative pressure is formed in the first induction air passage 101 and the second induction air passage 201. After the sensor 30 senses the pressure change, a differential pressure signal is generated and transmitted to the control board. After receiving the differential pressure signal, the control board controls the power supply device 20 to supply power to the atomizer 10. At this time, the e-liquid is atomized to generate smoke. At the same time, external gas sequentially enters the atomization chamber 1241 through the ventilation hole 211 and the air inlet hole 114 and mixes with the smoke to form a mixed flue gas. Under the suction action, the mixed flue gas finally enters the user's mouth through the ventilation pipe 14 via the smoking port 1321.

[0118] In this embodiment, there are two second communication holes 2011, and the two second communication holes 2011 are symmetrically distributed about the axis of the end cap 22. When the atomizer 10 is connected to the power supply device 20 at an angle, the first communication hole 1011 is aligned and communicates with one of the second communication holes 2011, and the other second communication hole 2011 is closed by the base 121. At this time, the first induction air passage 101 is connected to the second induction air passage 201, and the sensor 30 can be triggered to work when the user performs a suction operation. When the user rotates the atomizer 10 by 180° relative to the power supply device 20 and then connects it to the power supply device 20, the second communication hole 2011 that was initially in communication with the first communication hole 1011 is closed by the base 121, and the second communication hole 2011 that was initially closed by the base 121 is aligned and communicates with the first communication hole 1011. At this time, the first induction air passage 101 is still connected to the second induction air passage 201, and the sensor 30 can also be triggered to work when the user performs a suction operation.

[0119] The beneficial effects of the present invention are as follows: The electronic cigarette 100 of the present invention includes an atomizer 10 provided with an atomization chamber 1241 and a power supply device 20 detachably connected to the atomizer 10. An air inlet hole 114 communicating with the outside and the atomization chamber 1241 is formed on the atomizer 10, and an air vent hole 211 capable of communicating with the outside and the air inlet hole 114 is formed on the power supply device 20. The number of the air vent holes 211 is at least two, and the apertures of at least two air vent holes 211 are different. When the atomizer 10 is connected to the power supply device 20 at multiple angles, at least one air vent hole 211 communicates with the air inlet hole 114, thereby adjusting the intake air volume of the outside air entering the atomization chamber 1241. For the electronic cigarette of the present invention, by adjusting the intake air volume of the outside air entering the atomization chamber 1241, the resistance when the user smokes the mist is further adjusted to meet the usage requirements and experiences of different users.

The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
