Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, so that the technical solutions and the advantages thereof will be more clearly understood. It is to be understood that the drawings are provided for purposes of illustration and description only and are not intended as a definition of the limits of the invention, but the dimensions shown in the drawings are for convenience and are not to be taken as limiting the scale.

Referring to fig. 1, a sealable electronic cigarette according to a first embodiment of the present invention includes a battery assembly 10, an atomizer 20 electrically connected to the battery assembly 10, and a sealing cap 30 connectable to the battery assembly 10. The sealing cover 30 and the battery assembly 10 together enclose a receiving cavity for receiving the atomizer 20 therein when being connected. The battery assembly 10 is used for supplying power to the atomizer 20, and is provided with an air inlet 11. The atomizer 20 is provided with an air outlet 21, and the air inlet 11 on the battery assembly 10 is in air communication with the air outlet 21. A liquid storage cavity for storing tobacco tar and an air flow channel (not shown) are arranged in the atomizer 20, and the atomizer 20 can electrically heat the tobacco tar in the atomizer by means of the battery assembly 10 to form smoke, and the smoke travels along the air flow channel and is discharged from the air outlet 21 when being sucked by a user. Because the present invention is independent of the internal configuration and shape of the atomizer 20, any suitable configuration and configuration may be employed within the atomizer 20, as well as known configurations, which will not be described in detail herein.

A sealing member 40 is disposed between the sealing cover 30 and the battery assembly 10 to seal the receiving cavity. When the sealing cover 30 covers the battery assembly 10 to form the accommodating cavity, the atomizer 20 and the air inlet 11 on the battery assembly 10 are accommodated in the accommodating cavity. When the sealing cover 30 is disconnected from the battery assembly 10, the air intake holes 11 of the battery assembly 10 communicate with the outside atmosphere.

When the battery pack is used, the sealing cover 30 can be opened, so that the air inlet hole 11 on the battery pack 10 is communicated with the outside atmosphere, when a user sucks on the air outlet 21 on the atomizer 20, the outside atmosphere can enter the atomizer 20 through the air inlet hole 11, be mixed with smoke generated in the atomizer 20, and finally be discharged from the air outlet 21 on the atomizer 20 to be sucked by the user.

After use, the user can close the sealing cover 30 to make the sealing cover 30 and the battery assembly 10 form a sealed accommodating cavity, and then accommodate the atomizer 20 and the air inlet 11 on the battery assembly 10 in the sealed accommodating cavity. At this time, since the accommodating chamber is hermetically disposed, the air pressure in the accommodating chamber is constant, and the accommodating chamber is communicated with the airflow channel in the atomizer 20, that is, the pressure of the liquid storage chamber inside the atomizer 20 is consistent with the pressure of the accommodating chamber outside the atomizer 20. Therefore, even if bubbles are generated after the tobacco tar in the atomizer 20 is used, the bubbles will not expand and become large due to the pressure difference between the inside and the outside of the atomizer 20, and the problem of oil leakage caused by the fact that the tobacco tar in the atomizer 20 is extruded out of the liquid storage cavity due to the expansion and the enlargement of the bubbles is effectively avoided.

As shown in fig. 1 and 2, in the present embodiment, the battery assembly 10 includes a main body portion 13, a fence 14 located at an upper end of the main body portion 13 in an axial direction, and a battery (not shown) mounted in a cavity at a lower portion of the main body portion 13. The body portion 13 is of an integral sealed design. A first housing chamber 12 is formed in the enclosing wall 14 and is open at one end for housing a lower portion 22 of the atomizer 20. The bottom wall of the first accommodating cavity 12 is formed with a first conductive terminal 15A and a second conductive terminal 15B which are respectively electrically connected with the positive electrode and the negative electrode of the battery. In this embodiment, a sealing groove 16 is formed in the outer wall of the enclosing wall 14 for accommodating the sealing member 40. In this embodiment, the sealing element 40 is an annular sealing ring, and the sealing groove 16 extends and closes in the circumferential direction. The seal ring, and thus seal groove 16, may be disposed horizontally or at an angle to perimeter wall 14.

It will be appreciated that in other embodiments, the seal 40 may have other configurations and/or arrangements, such as two or more axially disposed seal rings, or two or more circumferentially disposed seal rings. Correspondingly, the seal groove 16 may be adapted according to the structure and/or arrangement of the seal 40. In this embodiment, the sealing member 40 is embedded in the sealing groove 16. In other embodiments, the sealing element 40 may be formed in the sealing groove 16 by other methods, such as injection molding.

The air inlet hole 11 is formed at the axial upper end of the enclosing wall 14 and above the sealing groove 16. The number of inlet holes 11 is preferably two and is arranged symmetrically with respect to the central axis of the enclosing wall 14. Preferably, a first position-limiting portion 17 is formed on the outer wall of the enclosing wall 14 and extends radially outwards for abutting against the sealing cover 30. The first stopper 17 is located below the seal groove 16. The radially outer side of the first stopper portion 17 may be flush with the radially outer side of the main body portion 13. A second stopper portion 18 may be formed at an axially lower end portion of the main body portion 13. Specifically, the diameter of the axially lower end of the main body portion 13 may be made smaller than the diameter of the remaining portion of the main body portion 13, thereby forming a stepped surface, i.e., the second stopper portion 18. When the seal cap 30 is detached from the surrounding wall 14, the seal cap 30 can be fitted into the second stopper portion 18 from the axial lower end of the main body portion 13, thereby preventing the seal cap 30 from being lost. It will be appreciated that the second limiting portion may be formed in other ways, such as a flange structure extending radially outward from the outer wall of the main body 13, and a second limiting portion formed at the axial lower end of the flange structure.

In this embodiment, the main body 13 includes a housing 130, and a battery holder 131 disposed in the housing 130. The upper end of the housing 130 extends to the surrounding wall 14 of the covering portion, and preferably abuts against the first limiting portion 17. The axially lower end of the battery holder 130 preferably protrudes beyond the axially lower end of the housing 130, thereby forming the second stopper portion 18. While in this embodiment the housing 130 and the battery holder 131 are described as distinct parts assembled together, it will be appreciated that in other embodiments the housing may also be integrally formed as part of the battery holder, i.e. as one piece.

In this embodiment, a certain gap is formed between the lower portion 22 of the atomizer 20 and the inner wall of the first receiving cavity 12, and the upper portion 23 of the atomizer 20 protrudes out of the first receiving cavity 12. Referring to fig. 1-3, the atomizer 20 includes first and second electrodes 24A, 24B partially protruding from the end surfaces of its lower portion 22. The first and second electrodes 24A, 24B are electrically connected to the first and second conductive terminals 15A, 15B, respectively, on the battery assembly 10, thereby powering the atomizer 20. Preferably, a first magnet 240 is disposed around at least one of the first and second electrodes 24A, 24B, and a second magnet 150 having a polarity opposite to that of the first magnet 240 is disposed around the first and second conductive terminals 15A, 15B corresponding to the first magnet 240. When the atomizer 20 is axially disposed in the first receiving cavity 12 of the battery assembly 10, the first magnet 240 and the second magnet 150 attract each other according to the principle of opposite attraction, so that the first and second electrodes 24A, 24B on the atomizer 20 are electrically connected to the first and second conductive terminals 15A, 15B on the battery assembly 10.

In this embodiment, the second magnet 150 is ring-shaped, and a cavity 151 is formed in the middle thereof. The first and second conductive terminals 15A and 15B are respectively inserted into the corresponding cavities 151 of the second magnet 150. The first and second conductive terminals 15A, 15B may protrude from the upper surface of the second magnet 150, or may be substantially flush with the upper surface of the second magnet 150. Accordingly, the first magnets 240 are circumferentially distributed around the first and second electrodes 24A, 24B corresponding to the second magnets 150. The lower end surfaces of the first and second electrodes 24A, 24B may be recessed inward with respect to the first magnet 240, or may be substantially flush with the lower surface of the first magnet 240, and the first and second electrodes 24A, 24B are preferably located at the center of the first magnet 240. In this embodiment, the first magnet 240 extends continuously radially outward from the outer periphery of its corresponding electrode 24A, 24B. It is understood that in other embodiments, the first magnet 240 may be annular similar to the second magnet 150 and form a cavity in the center thereof for the corresponding electrode 24A, 24B to pass through. In other embodiments, the second magnet 150 may also be formed by a continuous extension of the first magnet 240 in the present embodiment, that is, the second magnet extends continuously and radially outward from the outer circumference of the corresponding conductive terminal.

In order to improve the stability of the connection between the atomizer 20 and the battery pack 10, a catching hole 25 is preferably formed in the peripheral wall of the lower portion 22 of the atomizer 20. Correspondingly, the inner wall of the first receiving cavity 12 of the battery assembly 10 is formed with a fastening protrusion (not shown) which is in snap-fit connection with the fastening hole 25. The buckling protrusion can have certain elasticity. When the atomizer 20 is inserted into the first receiving cavity 12 of the battery assembly 10, the fastening protrusion is fastened into the fastening hole 25 of the atomizer 20 by using its own elastic deformation. It is understood that in other embodiments, the catching protrusion may be formed on the atomizer 20, and correspondingly, the catching hole is formed on the battery assembly 10.

In this embodiment, the air outlet 21 is formed at an end of an upper portion 23 of the atomizer 20. The air outlet 21 communicates with one end of an air flow passage in the atomizer 20. The end of the lower portion 22 of the atomizer 20 is also formed with an air inlet 26, and the air inlet 26 communicates with the other end of the air flow passage in the atomizer 20. The cross-section of the upper portion 23 of the atomizer 20 may be larger than the cross-section of the lower portion 22 of the atomizer 20, thereby forming a step surface 27 at the interface of the upper portion 23 and the lower portion 22 of the atomizer 20. In this way, after the atomizer 20 is inserted into the first receiving cavity 12 of the battery assembly 10, the step surface 27 abuts against the axial upper end of the battery assembly 10. When a user sucks on the air outlet 21, the outside atmosphere can enter the gap between the lower part 22 of the atomizer 20 and the battery assembly 10 through the air inlet hole 11 on the battery assembly 10, then enter the inside of the atomizer 20 from the air inlet 26 at the bottom end of the atomizer 20, and finally exit from the air outlet 21 at the top end of the atomizer 20 after being mixed with the smoke inside the atomizer 20.

As shown in fig. 1 and 4, the sealing cover 30 is formed in a cylindrical shape with one end open, and a second receiving cavity 31 communicating with the opening is formed therein. The second receiving chamber 31 may receive the upper portion 23 of the atomizer 20. In other words, in the present embodiment, the receiving cavity is formed by the first receiving cavity 12 and the second receiving cavity 31, and the receiving cavity is located at an axial end of the battery assembly 10. In other embodiments, other arrangements may be adopted, for example, most of the atomizer 20 is accommodated in the sealing cover 30 or the battery pack 10, as long as it is ensured that the atomizer 20 and the air inlet hole 11 on the battery pack 10 are accommodated in the closed accommodating cavity after the sealing cover 30 is covered on the battery pack 10.

In the present embodiment, as shown in fig. 1 and 5, the sealing cover 30 is connected to the battery assembly 10 in a plug-in fit manner. Specifically, the inner diameter of the open end of seal cover 30 is slightly larger than the outer diameter of enclosing wall 14, so that seal cover 30 can be axially inserted to and circumferentially wrapped around the outside of enclosing wall 14. In other embodiments, the sealing cover 30 and the battery assembly 10 may be connected in other ways, such as a flip-type pivot connection.

Preferably, when the sealing cover 30 is inserted into the battery assembly 10, the sealing member 40 is sandwiched between the sealing cover 30 and the surrounding wall 14, and two radial sides of the sealing member 40 respectively abut against a radial inner wall of the sealing cover 30 and an outer wall of the surrounding wall 14. In this way, the radially inner side of the sealing member 40 receives the pressing force of the outer wall of the enclosing wall 14, and the radially outer side of the sealing member 40 receives the pressing force of the inner wall of the sealing cover 30, and at the same time, the sealing member 40 generates a reaction force by its own elasticity to reversely press the outer wall of the enclosing wall 14 and the inner wall of the sealing cover 30, thereby forming a good sealing function. In other embodiments, the sealing groove 16 for receiving the sealing member 40 may be formed on the sealing cover 30.

In this embodiment, the cross section of the seal groove 16 is square. The square shape described herein may be either a rectangle or a square. The seal member 40 includes a main body portion 41 having a square cross section and a boss portion 42 formed radially outward of the main body portion 41, and the main body portion 41 and the boss portion 42 are integrally connected. The body 41 is accommodated in the seal groove 16 and abuts against the bottom wall of the seal groove 16. The boss 42 abuts against the inner wall of the seal cover 30. Preferably, the side of the protrusion 42 facing the plugging direction of the sealing cover 30 is a slope inclined toward the plugging direction of the sealing cover 30, so as to reduce the mechanical resistance of the sealing member 40 to the sealing cover 30 and facilitate the insertion of the sealing cover 30. It is also possible to make the side of the protruding portion 42 facing away from the plugging direction of the sealing cover 30 be an inclined surface, in other words, the cross section of the protruding portion 42 in this embodiment is triangular. It will be appreciated that in other embodiments, the cross-section of the boss 42 may be arcuate.

When the electronic cigarette in this embodiment is assembled, the sealing member 40 is first embedded into the sealing groove 16 of the battery assembly 10, then the atomizer 20 is inserted so that the lower portion 22 of the atomizer 20 is accommodated in the first accommodating cavity 12 of the battery assembly 10, and finally the sealing cover 30 is inserted to abut against the first limiting portion 17 of the battery assembly 10, so that a sealed accommodating cavity is formed between the sealing cover 30 and the battery assembly 10, wherein the atomizer 20 and the air inlet 11 on the battery assembly 10 are both accommodated in the sealed accommodating cavity. In use, the user can pull out the sealing cover 30 and insert the sealing cover 30 along the opposite insertion direction to abut against the second limiting portion 18 of the battery assembly 10.

As shown in fig. 1, in the present embodiment, the whole electronic cigarette is flat, that is, the battery assembly 10, the atomizer 20 and the sealing cover 30 are flat, so that the electronic cigarette is convenient for a user to hold and insert. Preferably, the plane in which the open end of the sealing cover 30 is located is designed to be at an angle with respect to the cross-section of the battery assembly 10, that is, the sealing cover 30 has a different length on one side from the opposite side. Accordingly, the first position-limiting part 17 and the second position-limiting part 18 on the battery pack 10 are also designed at the same angle to the cross section of the battery pack 10. Therefore, the electronic cigarette is more attractive overall.

A gap is formed between the sealing member 140 and the inner wall of the sealing groove 16, thereby providing a deformation space for the sealing member 140. The sealing cover 30 is axially inserted into the sealing groove and abuts against the first limiting portion 17 on the enclosing wall 14, and the sealing element 140 is pressed, so that the radial inner side of the sealing element 140 abuts against the bottom wall of the sealing groove 16, and the radial outer side of the sealing element 140 also abuts against the inner wall of the sealing cover 30, thereby forming a good sealing effect.

The seal 240 is disposed in the seal groove 16, and the seal 240 is preferably disposed in a direction parallel to the axis of the enclosing wall 14 along the long axis of the cross section of the seal 240, so that both axial ends of the seal 240 respectively abut against the two axial end walls of the seal groove 16, the radially inner side of the seal 240 abuts against the bottom wall of the seal groove 16, and the radially outer side of the seal 240 protrudes out of the seal groove 16. A certain gap is formed between the sealing member 240 and the inner wall of the sealing groove 16, thereby providing a certain deformation space for the sealing member 240. The sealing cover 30 is axially inserted into the sealing groove and abuts against the first limiting portion 17 on the enclosing wall 14, and the sealing member 240 is pressed, so that the radial inner side of the sealing member 240 abuts against the bottom wall of the sealing groove 16, and the radial outer side of the sealing member 240 also abuts against the inner wall of the sealing cover 30, thereby forming a good sealing effect.

Fig. 8 is a schematic partial cross-sectional view of an electronic cigarette according to a fourth embodiment of the present invention, in which the cross-section of the sealing member 140 is circular, similar to the second embodiment. The main differences between this embodiment and the second embodiment are: the cross-section of seal groove 116 is U-shaped. Seal groove 116 in this embodiment is formed in perimeter wall 14 of cell assembly 10.

The sealing member 140 maintains a certain gap from the junction of the aforementioned curved surface, thereby providing a certain deformation space for the sealing member 140. The sealing cover 30 is axially inserted into the first limit portion 17 of the enclosing wall 14 and presses the sealing member 140, so that the radial inner side of the sealing member 140 abuts against the bottom wall of the sealing groove 116, and the radial outer side of the sealing member 140 also abuts against the inner wall of the sealing cover 30, thereby forming a good sealing effect.

Fig. 9 is a schematic partial cross-sectional view of an electronic cigarette according to a fifth embodiment of the present invention, and the main difference between the present embodiment and the fourth embodiment is: the two end wall portions of the sealing groove 216 corresponding to the opening thereof, i.e., the joint between the axial end wall of the sealing groove 216 and the outer wall of the enclosing wall 14, are curved. This arrangement not only facilitates embedding the seal 140 within the seal groove 216, but also reduces wear on the seal 140, thereby increasing the useful life of the seal 140.

The main differences between this embodiment and the fourth embodiment are: the radial inner side of the sealing member 340 is provided with a groove 341. When the gas enters the groove 341 of the sealing member 340, the sealing member 340 expands outward and tightly fits against the inner wall of the sealing groove 116 and the inner wall of the sealing cover 30, which contributes to the improvement of the sealing effect. In this embodiment, groove 341 in seal 340 has a V-shaped cross-section that opens toward the bottom wall of seal groove 116. In other embodiments, the cross-section of the groove 341 may have other shapes such as a U-shape.

The seal 140 is disposed in the seal groove 316, the seal 140 abuts against two sidewalls of the seal groove 316, and a radially outer side of the seal 140 protrudes from the seal groove 316. A gap is maintained between the sealing member 140 and the sidewall of the sealing groove 316, thereby providing a deformation space for the sealing member 140. The sealing cover 30 is axially inserted into the first limit portion 17 of the enclosing wall 14 and presses the sealing member 140, so that the radial inner side of the sealing member 140 abuts against the side wall of the sealing groove 316, and the radial outer side of the sealing member 140 also abuts against the inner wall of the sealing cover 30, thereby forming a good sealing effect.

Fig. 13 is a schematic partial cross-sectional view of an electronic cigarette according to a ninth embodiment of the present invention, and the main difference between this embodiment and the eighth embodiment is: the two sidewalls of the sealing groove 416 corresponding to the opening, i.e. the connection between the sidewall of the sealing groove 416 and the outer wall of the enclosing wall 14, are curved. This arrangement not only facilitates embedding the seal 140 within the seal groove 416, but also reduces wear on the seal 140, thereby increasing the useful life of the seal 140.

Fig. 14 is a schematic partial cross-sectional view of an electronic cigarette according to a tenth embodiment of the present invention, similar to the eighth embodiment, in which a sealing groove 316 is formed on an enclosure wall 14 of a battery assembly 10, and the cross-section of the sealing groove 316 is V-shaped. The main difference between this embodiment and the eighth embodiment is that: the radial inner side of the sealing member 340 is provided with a groove 341. When the gas enters the groove 341 of the sealing member 340, the sealing member 340 expands outward and tightly fits against the sidewall of the sealing groove 316 and the inner wall of the sealing cover 30, which contributes to the improvement of the sealing effect. In this embodiment, the cross-section of the groove 341 on the sealing element 340 is V-shaped, and the opening of the V-shaped groove 341 faces the bottom of the sealing groove 316, i.e., the tip portion of the V-shaped sealing groove 316. In other embodiments, the cross-section of the groove 341 may have other shapes such as a U-shape.

Fig. 15 is a schematic partial cross-sectional view of an electronic cigarette according to an eleventh embodiment of the present invention, and the main difference between this embodiment and the tenth embodiment is: the two sidewalls of the sealing groove 416 corresponding to the opening, i.e. the connection between the sidewall of the sealing groove 416 and the outer wall of the enclosing wall 14, are curved. This arrangement not only facilitates embedding the seal 340 within the seal groove 416, but also reduces wear on the seal 340, thereby increasing the useful life of the seal 340.
