[0025] As currently contemplated, the present disclosure describes the best mode or practice mode of the present invention. The present invention is not intended to be understood in a limiting sense, but rather provides illustrative examples of the invention by way of the accompanying drawings to inform those of ordinary skill in the art of the advantages and construction of the present invention. In the various views of the drawings, like reference numerals refer to the same or similar components.

[0026] Figure 1 is a schematic diagram of the overall appearance of an electronic cigarette, where (a) is a schematic diagram in the side view direction and (b) is a schematic diagram in the top view direction; Figure 2 is a schematic diagram of the internal structure of the electronic cigarette with the rear housing omitted; Figure 3 is a schematic diagram of a partial internal structure of the electronic cigarette with the housing omitted, referring to Figures 1 to 3 , the electronic cigarette includes a housing 1, and the housing 1 is generally cylindrical or drum-shaped. In order to facilitate the user's hand to hold (improve the user's hand-holding feeling), the side portion (radial outer circumference) of the housing 1 is arc-shaped. Specifically, the cross-sectional area of the housing 1 gradually increases from the two axial ends towards the axial middle. The middle of the housing 1 is hollow to form an accommodation cavity 11. Among them, the housing 1 includes an upper housing 103, a lower housing 104, a front housing 105, and a rear housing 106. The front housing 105 and the rear housing 106 can be snapped together through a known snap structure to form the main body of the housing 1 that is generally cylindrical or drum-shaped. The upper housing 103 covers the accommodation cavity 11 from above the main body of the housing 1, and the lower housing 104 covers the accommodation cavity 11 from below the main body of the housing 1. The upper housing 103 and the lower housing 104 can also be snapped together with the main body of the housing 1 through a known snap structure. In addition, the upper housing 103 and the lower housing 104 can also be fixed to the main body of the housing 1 by means of, for example, interference fit. For example, mounting pins (not shown) are respectively provided on the upper housing 103 and the lower housing 104, and fixing holes (not shown) are provided at both axial ends of the front housing 105 and / or the rear housing 106. By inserting the mounting pins into the fixing holes in an interference fit manner, the upper housing 103 and the lower housing 104 are respectively fixed to both axial ends of the main body of the housing 1 formed by snapping the front housing 105 and the rear housing 106 together, thereby forming the accommodation cavity 11.

[0027] The accommodating cavity 11 accommodates an atomizer unit 2. The atomizer unit 2 is slidably disposed within the accommodating cavity 11. The atomizer unit 2 includes a base 23, an atomizer body 22, and a mouthpiece 21. The atomizer body 22 is mounted on the base 23. An electrifying interface (such as the electrode pins 47a, 47b described below) is provided on the base 23, and the electrifying interface can be electrically connected to the wire of the control board 8. The mouthpiece 21 and the atomizer body 22 are detachably mounted to facilitate the operator to replace the mouthpiece 21. For example, the mouthpiece 21 is a silicone member and is sleeved onto the atomizer body 22. A first outlet portion 101 communicating with the accommodating cavity 11 is formed at the upper end portion of the housing 1, that is, the first outlet portion 101 is formed on the upper housing 103. When the atomizer unit 2 slides within the accommodating cavity 11, the mouthpiece 21 can extend out of the housing 1 (accommodating cavity 11) via the first outlet portion 101, or retract from the outside of the housing into the housing 1 (accommodating cavity 11) via the first outlet portion 101. When the mouthpiece 21 extends out of the housing 1, the user can smoke. When the mouthpiece 21 retracts into the accommodating cavity 11, since the mouthpiece 21 can be completely received within the accommodating cavity 11, it is possible to prevent the atomizer unit 2 (such as the mouthpiece 21 of the atomizer unit 2) from being exposed outside the electronic cigarette and prevent dust contamination. And since the atomizer unit 2 is received within the accommodating cavity 11, the electronic cigarette is in a smooth cylindrical or drum shape as a whole, so it is convenient for the user to carry.

[0028] In addition, a battery 9, a control board 8 (PCB board), and necessary wires (such as power supply wires) are also accommodated within the accommodating cavity 11. The battery 9 can be a rechargeable battery 9. The battery 9 is electrically connected to the control board 8 to supply power to the control board 8. The control board 8 is electrically connected to the atomizer unit 2 to control the operation (such as heating) of the atomizer unit 2. The battery 9 and the control board 8 can be installed within the accommodating cavity 11 in any known manner. A charging interface mounting seat 108 communicating with the accommodating cavity 11 is formed at the bottom of the housing 1, that is, the charging interface mounting seat 108 is formed on the lower housing 104. A charging interface for charging the battery 9, such as a Type-C interface, or any other charging interface well-known to those skilled in the art, can be mounted on the charging interface mounting seat 108. The control board 8 can also be a control board 8 well-known in the technical field of electronic cigarettes to control the heating of the atomizer body 22. A working indicator light 81, a main function button 82 for turning off or on the atomizer body 22, or a gear adjustment button 83 for adjusting the operation of the atomizer unit 2 can be provided on the control board 8. Correspondingly, communication holes 107 allowing these working indicator light 81, main function button 82, and gear adjustment button 83 to be exposed outside the housing 1 can be formed on the side portion of the housing 1 to facilitate the user to operate the electronic cigarette.

[0029] As described above, the atomizer part 2 is slidably arranged in the accommodation cavity 11. To enable the sliding of the atomizer part 2 so that the mouthpiece 21 extends out of the housing 1 or retracts from the outside of the housing 1 into the accommodation cavity 11, the electronic cigarette of this embodiment is provided with a pushing part 3. The pushing part 3 is connected to the atomizer part 2 in the accommodation cavity 11. Specifically, the pushing part 3 includes a connecting seat 32 and a pushing head 31. The connecting seat 32 and the pushing head 31 can be integrally formed. The connecting seat 32 is connected to the base 23 of the atomizer part 2 in the accommodation cavity 11. For example, it can be directly sleeved onto the base 23 of the atomizer part 2, or directly integrally formed with the base 23 of the atomizer part 2, or the connecting seat 32 can also be connected to the base 23 by other means such as magnets or adhesives. The pushing head 31 is exposed outside the housing 1 for the user to slide the pushing head 31 conveniently. To expose the pushing head 31 outside the housing 1, a first groove part 102 communicating with the accommodation cavity 11 is opened on the side of the housing 1. The connecting seat 32 of the pushing part 3 is connected to the atomizer part 2 in the accommodation cavity 11, and the pushing head 31 is exposed outside the housing 1 through the first groove part 102. The first groove part 102 is in a long strip shape and can be opened on the front housing 105, or on the rear housing 106, or notches are respectively opened on the front housing 105 and the rear housing 106. When the front housing 105 and the rear housing 106 are engaged, the two notches together form the first groove part 102. When the pushing head 31 is pushed along the first groove part 102, it drives the mouthpiece 21 to expand and contract.

[0030] Figure 4 is Figure 3 an exploded schematic view of a part of the internal structure of the electronic cigarette, referring to Figure 4 and continuing to refer to Figure 3 Preferably, to facilitate guiding the sliding of the atomizer part 2, the electronic cigarette of this embodiment further includes a guiding part 5. The guiding part 5 is accommodated in the accommodation cavity 11. In an alternative embodiment, the guiding part 5 includes a first sliding groove 51 and a first sliding member 52 sliding in the first sliding groove 51. The first sliding groove 51 is arranged on the housing 1, and the first sliding member 52 is arranged on the atomizer part 2. Specifically, the first sliding member 52 can be a guide post and is integrally formed with the base 23 of the atomizer part 2. The first sliding groove 51 can be directly integrally formed on the front housing 105 and / or the rear housing 106. To simplify the structure of the front housing 105 or the rear housing 106, a sliding track 53 can also be installed in the accommodation cavity 11. The sliding track 53 can also be installed on the front housing 105 and / or the rear housing 106 by any well-known method, such as through a mounting pin 531, and is accommodated in the accommodation cavity 11. The first sliding groove 51 is arranged on the sliding track 53. It should be noted that the front housing 105 and the rear housing 106 of this embodiment can be injection-molded. The snap structures or other mounting structures mentioned in this embodiment can all be directly injection-molded on the front housing 105 or the rear housing 106.

[0031] To prevent the atomizer part 2 from rotating when sliding, preferably, the first sliding members (guide posts) 52 can be provided in two places, respectively located on both sides of the base 23 in the radial direction. Correspondingly, the sliding tracks 53 having the first sliding grooves 51 also include two places, and are respectively installed in the accommodation cavity 11 corresponding to the first sliding members 52. In addition, to prevent the nozzle 21 from swinging when the atomizer part 2 slides, in the upper part of the accommodation cavity 11, that is, at the telescopic path of the nozzle 21, a sleeve 54 for guiding the sliding of the nozzle 21 can also be provided. Similarly, the sleeve 54 can also be installed in the accommodation cavity 11 through the installation structure (not shown) provided on the front housing 105 and / or the rear housing 106.

[0032] To enable the atomizer part 2 to stop at a preset position after sliding to the preset position, the electronic cigarette of the present embodiment is further provided with a stopping part 4. The stopping part 4 is arranged in the accommodation cavity 11 and is configured to enable the nozzle 21 to stop at the preset position. Here, the preset position refers to the specific position where the nozzle 21 can extend or retract that the user can choose according to their personal preference.

[0033] Figure 5 is a schematic diagram of an embodiment of the stopping part 4. Refer to Figure 5 and continue to refer to Figure 3 、 Figure 4 , and the stopping part 4 will be described in detail in combination with various embodiments.

[0034] Embodiment 1

[0035] Refer to Figures 2 to 4, in the first embodiment, the stopping part 4 includes a stopper (herein, also called the first stopper) 41 provided on the housing 1 and an elastic member (herein, also called the first elastic member) 42 connected to the atomizer part 2. The first stopper 41 is provided on the housing 1. For example, the first stopper 41 is plate-shaped, the first stopper 41 is clamped on the front housing 105 and accommodated in the accommodation cavity 11. At least at both ends in the length direction of the first stopper 41, first card slots 411 opposite to the atomizer part 2 are respectively provided. The first elastic member 42 can be mounted on the base 23 of the atomizer part 2. Specifically, the atomizer part 2 further includes a first fixing member 24 located below the base 23. The first fixing member 24 can be clamped tightly to the base 23, and the first elastic member 42 is fixed to the first fixing member 24 of the atomizer part 2. The first elastic member 42 slides along the length direction of the first stopper 41 and can be caught by the first card slot 411. Herein, by providing the first card slots 411 at least at both ends in the length direction of the first stopper 41, the atomizer part 2 can be made to stop stably at least at the position where the mouthpiece 21 retracts and the position where the mouthpiece 21 extends (i.e., the preset positions). Thus, it is convenient for the storage of the mouthpiece 21 (when the mouthpiece 21 retracts) and convenient for the user to smoke (when the mouthpiece 21 extends).

[0036] Second Embodiment

[0037] Refer to Figure 4 , the second embodiment is substantially the same as the first embodiment, except that in order to enable the mouthpiece 21 to stay at multiple positions, the first card slots 411 can include multiple parts and are distributed along the length direction of the first stopper 41. For example, on the first stopper 41, an extension band 45 extending in a wavy line along the length direction of the first stopper 41 can be provided, and each trough part 451 of the extension band 45 is used as the first card slot. The first elastic member 42 abuts against the extension band 45 and slides on the extension band 45 as the push head 31 pushes the atomizer part 2. When the first elastic member 42 slides to the trough part 451, the first elastic member 42 fits to the trough part 451. Thus, the first elastic member 42 is restricted by the two peak parts 452 located at the trough part 451, so that the atomizer part 2 can stop at a specific position. When the push head 31 is pushed to make the atomizer part 2 slide, the first elastic member 42 is squeezed by the peak part 452 of the extension band 45 and contracts and slides on the extension band 45.

[0038] Third Embodiment

[0039] Refer to Figure 5, Embodiment 3 is substantially the same as Embodiment 1, except that the stopper (also referred to as the second stopper) 43 and the elastic member (also referred to as the second elastic member) 44 of the stopper portion 4 are conductive members. For example, the materials of the second stopper 42 and the second elastic member 44 can be selected as copper materials. Specifically, while the second stopper 43 is fixed to the housing 1 in the same manner as the first stopper 41, it is connected to the terminal of the control board 8 (not shown, and can be electrically connected by any known method such as conductive connection). The second stopper 43 is provided with second card slots 431 opposite to the atomizer portion 2 at least at both ends in the length direction. The second elastic member 44 is electrically connected to one end of the power connection terminal of the atomizer portion 2 (for example, the upper power connection interface end provided on the base 23) (not shown, and can be electrically connected by any known method such as conductive connection). The second elastic member 44 always abuts against the second stopper 43. The other terminals of the control board 8 and the other end of the power connection of the atomizer portion 2 (for example, the upper power connection interface end provided on the base 23) can be connected by known conductive wires to electrically connect the control board 8 and the atomizer portion 2. The second elastic member 44 slides on the second stopper 43 as the push head 31 pushes the atomizer portion 2 and can be caught by the second card slot 431. Thus, not only can the mouthpiece 21 be stopped at a preset position, but also since the stopper portion 4 is directly used as a conductive member connecting the battery 9 and the atomizer portion 2, some follower conductive wires can be omitted.

[0040] Embodiment 4

[0041] Continue to refer to Figure 5 , Embodiment 4 is substantially the same as Embodiment 2, except that the stopper and the elastic member of the stopper portion 4 are conductive members. As described above, for the sake of distinction, the conductive stopper is also collectively referred to as the second stopper 43, and the conductive elastic member is collectively referred to as the second elastic member 44. Specifically, while the second stopper 43 is fixed to the housing 1 in the same manner as the first stopper 41, it is electrically connected to one end of the control board 8. In the middle of the first stopper 41, an extension band 45 extending in a wavy line along the length direction of the second stopper 43 is provided, and each trough portion 451 of the extension band 45 is used as a second card slot. The second elastic member 44 is connected to one end of the terminal of the atomizer portion 2 (for example, the upper power connection interface end provided on the base 23). The second elastic member 44 always abuts against the extension band 45 of the second stopper 43. The other ends of the terminals of the control board 8 and the other ends of the terminals of the atomizer portion 2 can be connected by known conductive wires to electrically connect the control board 8 and the atomizer portion 2. Thus, not only can the mouthpiece 21 be stopped at multiple preset positions, but also since the stopper portion 4 is directly used as a conductive member connecting the control board 8 and the atomizer portion 2, some follower conductive wires (i.e., the conductive wires that move as the atomizer portion slides) can be omitted.

[0042] Embodiment 5

[0043] Continue to refer to Figure 5 , the fifth embodiment is substantially the same as the fourth embodiment, except that the stopper 4 includes two locations, one end of the wiring of the atomizer portion 2 (not shown) is electrically connected to one end of the wiring of the control board 8 (not shown) through one stopper 4, and the other end of the wiring of the atomizer portion 2 (not shown) is electrically connected to the other end of the wiring of the control board 8 (not shown) through another stopper 4. It should be noted that, here, the wiring terminals of the atomizer portion 2 and the control board 8 refer to the wiring terminals electrically connected to the two. Specifically, the second stoppers 43 of the two stopper portions 4 are respectively fixed to the housing 1, and the two second stoppers 43 can be respectively located on the same side of the atomizer portion 2, or respectively located on the radially opposite sides of the atomizer portion 2. For example, the two second stoppers 43 can be fixed to the front housing 105, and the other second stopper 43 can be fixed to the rear housing 106, or both can be fixed to the front housing 105 or the rear housing 106. Preferably, in order to make the atomizer part 2 slide more steadily and smoothly, the two second stoppers 43 are respectively located on opposite sides of the atomizer part 2 in the radial direction. In contrast, the second elastic members 44 of the two stoppers 4 are respectively mounted on the base 23 of the atomizer part 2, wherein one second elastic member 44 abuts against one second stopper 43, and the other second elastic member 44 abuts against the other second stopper 43. Thus, since a stopper 4 capable of conducting electricity is added on the basis of the fourth embodiment, not only can the mouthpiece 21 be more stably kept at a plurality of preset positions, but also the redundant follow-up conductive wire can be directly omitted.

[0044] Embodiment 6

[0045] Reference Figure 3 , the sixth embodiment is substantially the same as the second embodiment, except that two electrode sheets 46a and 46b are further installed on the first stopper 41, and the electrode sheets 46a and 46b are respectively located on both sides of the width direction of the extension belt 45, and are in the same extension direction as the extension belt 45, one of the electrode sheets 46a is connected to one end of the battery 9 connected to electricity, and the other electrode sheet 46b is connected to the other end of the battery 9 connected to electricity. Correspondingly, two electrode needles 47a and 47b (power-on interfaces) are installed on the base 23 of the atomizer part 2, one of the electrode needles 47a abuts against one of the electrode sheets 46a, and the other electrode needle 47b abuts against the other electrode sheet 46a. Thus, the redundant follow-up conductive wire can be directly omitted.

[0046] Figure 6 is a schematic diagram of the internal structure of another embodiment of the electronic cigarette, referring to Figures 2 to 5 , and refer to Figure 6, the elastic members (the first elastic member 42 and the second elastic member 44) will be described in detail below in combination with the above embodiments and other embodiments.

[0047] Referring to Figures 2 to 5 , in an alternative embodiment, the first elastic member 42 (or the second elastic member 44) may be selected as a spring pin member (pogo pin member). Specifically, the first fixing member 24 is plate-shaped and can be clamped between two first sliding members (guide posts) 52. The first fixing member 24 is substantially parallel to the first stopper 41. The first elastic member 42 (or the second elastic member 44) serving as a spring pin member is vertically mounted on the first fixing member 24. Thus, the spring pin member also substantially vertically abuts against the extension band 45 of the first stopper 41 (or the second stopper 43), and elastically expands and contracts as the atomizer portion 2 slides, so as to slide along the peak portion 452 and the valley portion 451 of the extension band 45. When the telescopic end of the spring pin member fits with the valley portion 451, the atomizer portion 2 can be stably stopped. Thus, it is possible to ensure that the mouthpiece 21 stays at a preset position.

[0048] Referring to Figure 6 , in another alternative embodiment, the first elastic member 42 (or the second elastic member 44) may be selected as a spring sheet member. For example, the elastic sheet is a sheet metal part with a thickness of about 0.2 mm. The elastic sheet has a mounting end 42a and a cantilever end 42b. The mounting end 42a is clamped between the base 23 and the second fixing member 25. The second fixing member 23 can be directly locked to the base 23 by screws. The cantilever end 42b abuts against the extension band 45 of the first stopper 41 (or the second stopper 43), and elastically swings as the pusher 31 pushes the atomizer portion 2, so as to slide along the peak portion 452 and the valley portion 451 of the extension band 45, and when the cantilever end 42b fits with the valley portion 451, the atomizer portion 2 is stably stopped. Thus, it is possible to ensure that the mouthpiece 21 stays at a preset position. It should be noted that when there are two spring sheet members (such as the second elastic member 44 in Embodiment 5), in order to prevent conduction between the two spring sheet members, an insulating member may be provided between the two spring sheet members.

[0049] Continuing to refer to Figure 6, In addition, to prevent the atomizer unit 2 from retracting to a preset position, preferably, the electronic cigarette of the present embodiment further includes an anti-retraction portion 6. The anti-retraction portion 6 is accommodated in the accommodation cavity 11. The anti-retraction portion 6 includes a ratchet rack 61 and a pawl 62. The ratchet rack 61 is provided on the housing 1, and the pawl 62 is connected to the push head 31. When the push head 31 is pressed, the pawl 62 disengages from the ratchet rack 61. Specifically, when the atomizer unit 2 stays at a certain preset position through the stopping portion 4, the atomizer unit 2 is simultaneously caught by the ratchet rack 61 of the anti-retraction portion 6 corresponding to the same stopping portion 4 through the pawl 62. The ratchet rack 61 can be directly integrally formed on the housing 1, for example, directly formed on the front housing 105 and / or the rear housing 106 and accommodated in the accommodation cavity 11. In contrast, the pawl 62 can be integrally formed on the base 23 of the atomizer unit 2 or the second fixing member 25 (or the first fixing member 24), extend in the direction of the ratchet rack 61 and can be caught on the ratchet rack 61. Thereby, it is possible to prevent the atomizer unit 2 from retracting and causing the mouthpiece 21 to retract. The base 23 or the second fixing member 25 (or the first fixing member 24) is made of an elastic material such as polyurethane or soft plastic. Since the push head 31 is connected to the pawl 62 through the base 23 or the second fixing member 25 made of an elastic material, when the push head 31 is pressed, the pawl 62 contracts along with the base 23 or the second fixing member 25, so that the pawl 62 and the ratchet rack 61 are disengaged.
