[0056] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in this document are for illustrative purposes only and are not limiting.
[0057] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.
[0058] like Figure 1 As shown, the utility model provides an electronic cigarette 1, which can not only adjust the air intake to make the inhalation resistance adjustable, but also realize the child lock function. The inhalation resistance of an electronic cigarette refers to the difficulty or resistance of inhalation felt by the user when using the electronic cigarette. Specifically, when simulating the smoking action of a person on the electronic cigarette, a certain vacuum pressure is generated at the inhalation end of the electronic cigarette. This pressure is the resistance to inhalation, usually referred to as the inhalation resistance. Different inhalation resistances bring different tastes to the user. The child lock function of the electronic cigarette is mainly to prevent children from contacting and using electronic cigarette products to prevent accidents.
[0059] The electronic cigarette 1 includes a housing 2, a battery 3 located inside the housing 2, a heating wire 4 and other components / devices, and an electronic cigarette base 7 located at the bottom of the housing 2. The battery 3 supplies power to the heating wire 4, and the heat from the heating wire 4 can volatilize the smoke oil to form smoke oil gas. The housing 2 has a mouthpiece 6 at the top and an airway 5 located inside and connected to the mouthpiece 6. The electronic cigarette base 7 is provided with an air inlet 11 connected to the airway 5 (see Figure 3 ), the gas enters the electronic cigarette 1 from the air inlet 11, and the gas mixed with the atomized smoke oil gas enters the user's mouth through the airway 5 and the mouthpiece 6.
[0060] It should be noted that the directional terms used in this article, such as "top", "bottom", "upper", "lower", etc., are relative to Figure 1 This is for the electronic cigarette 1 which is placed vertically as shown.
[0061] The electronic cigarette base 7 of the utility model can realize adjustable suction resistance and child lock functions. Figures 2 to 7 The electronic cigarette base 7 according to the first embodiment of the utility model is shown. Figures 2 to 4 As shown, the electronic cigarette base 7 includes a base body 10 and an adjustment button 20. The base body 10 has a bottom wall and an annular side wall, and the side wall can be connected to the housing 2, for example, plugged. The bottom wall of the base body 10 is provided with an air inlet. The adjustment button 20 is connected to the base body 10 and has at least two suction resistance positions (such as the first direction D1) for opening the air inlet. Figure 5 and Figure 6 ) and the child lock position with the air intake closed (as shown Figure 7 When the adjustment button 20 is in the suction resistance position, the air inlet is open, not blocked, connected to the environment, and gas can enter from the air inlet. The opening degree or opening area of the air inlet 11 corresponding to different suction resistance positions is different, so the air intake volume is different. When the adjustment button 20 is in the child lock position, the air inlet is closed, blocked by the adjustment button 20, not connected to the environment, and the gas is blocked.
[0062] The adjustment button 20 moves in a straight line relative to the base body 10 between the inhalation resistance position and the child lock position, which can also be said to be sliding. Before using the electronic cigarette 1, the user manually turns the adjustment button 20 to switch the electronic cigarette 1 from the child lock state to the use state (i.e., the inhalation resistance state); after use, the user switches the electronic cigarette 1 from the use state to the child lock state by reversely turning the adjustment button 20. The adjustment button 20 moves in a straight line relative to the base body 10 between different inhalation resistance positions. When using the electronic cigarette 1, the user manually turns the adjustment button 20 to switch the electronic cigarette 1 between different inhalation resistance states to adjust the gas intake amount, thereby adjusting the inhalation resistance.
[0063] Of course, if needed and / or desired, the number of the suction resistance position can be one, thus, the number of the suction resistance position is at least one. When there is one suction resistance position, the adjustment button 20 moves between the one suction resistance position and the child lock position.
[0064] Alternatively, the adjustment button 20 may be configured to move in a rotational manner instead of in a linear manner. By rotating the adjustment button 20, it is switched between different positions including the suction resistance position and the child lock position. The following is a specific description using the adjustment button 20 that moves in a linear manner in the illustrated embodiment as an example.
[0065] The base body 10 is provided with at least two air inlet holes along the first direction D1, and the number of the air inlet holes is, for example, two, three, four, five, or any other suitable value. Each air inlet hole corresponds to a suction resistance position, so the number of suction resistance positions corresponds to any other suitable value, such as two, three, four, five, or any other suitable value. The apertures of different air inlet holes can be the same or different. In the illustrated embodiment, the number of air inlet holes is two, and the apertures are the same, so that the adjustment button 20 has a first suction resistance position and a second suction resistance position. Figure 5 As shown, when the adjustment button 20 is in the first suction resistance position, both air inlet holes are open, and the air intake volume is relatively large, so the first suction resistance position is also called the large suction resistance position. Figure 6 As shown, when the adjustment button 20 is in the second suction resistance position, one of the two air inlet holes is open and the other is closed, and the air intake amount of the gas is small, so the first suction resistance position is also called the small suction resistance position. Figure 7 As shown, when the adjustment button 20 is in the child lock position, the two air inlet holes are closed and the air intake amount is zero.
[0066] In order to operate the adjustment button 20 more stably, the electronic cigarette base 7 also includes a limit plate 30, which is arranged inside the base body 10 and is connected to the adjustment button 20 and the two move together. A first limit portion 15 is provided inside the base body 10, and correspondingly, the limit plate 30 is provided with a second limit portion 31. When the adjustment button 20 is located at the suction resistance position and / or the child lock position, the first limit portion 15 and the second limit portion 31 cooperate with each other through a concave-convex structure. By providing the limit plate 30, the concave-convex structure between the limit plate 30 and the base body 10 can provide movement resistance for the adjustment button 20, so that the adjustment button 20 is stably maintained at the desired suction resistance position and child lock position, and the adjustment button 20 is prevented from being accidentally touched and moved.
[0067] The number of suction resistance positions is at least two, and correspondingly, the number of the first limit portion 15 or the second limit portion 31 is at least three. The adjustment button 20 shifts between different positions through the concave-convex structure. Through the concave-convex structure of the limit piece and the base body 10, the adjustment button 20 can have a gear operation sense, so that the user has a better operation sense when turning the adjustment button 20, and can accurately slide the adjustment button 20 to the suction resistance position or the child lock position, thereby improving the user experience.
[0068] The second limiting portion 31 can match the first limiting portion 15 in shape and size. The limiting piece 30 not only has the function of installing and fixing the adjustment button 20, but also has the function of providing the operating sense of the gear position. It has multiple uses, reduces the number of parts on the electronic cigarette base 7, and simplifies the structure of the electronic cigarette base 7. The number of positions of the adjustment button 20 is A, and the concave-convex structure can realize A gear positions, that is, the adjustment button 20 has A gear positions.
[0069] The first limiting portion 15 cooperates with the second limiting portion 31 in the up-down direction D3. That is, the first limiting portion 15 is located below the second limiting portion 31, and the first limiting portion 15 can be formed on the boss 13, for example, on the top surface of the boss 13.
[0070] Optionally, the first limit portion 15 is a concave portion, and the second limit portion 31 is a convex portion. If needed and / or desired, the first limit portion 15 is a convex portion, and the second limit portion 31 is a concave portion. One example is that the number of convex portions is N times the number of positions of the adjustment button 20, N ≥ 1; the number of concave portions is less than the number of convex portions; another example is that the number of concave portions is the same as the number of positions of the adjustment button 20, and the number of convex portions is less than the number of concave portions. In the illustrated embodiment, the concave portion is specifically recessed downward from the top surface of the boss 13; a convex portion protruding downward can be formed by bending the limit piece 30 as a whole. The number of concave portions is N times the number of positions of the adjustment button 20, and the number of convex portions is 1 / N times the number of concave portions. With such a configuration, a concave-convex matching structure is formed, which increases the operational feel of the gear position, has a simple structure, and is easy to manufacture.
[0071] Return to see Figure 2 and Figure 3, the adjustment button 20 includes an operating portion 21 for opening and closing the air inlet and a columnar portion 22 for installation. The columnar portion 22 is connected to the middle part of the operating portion 21. In order to install the adjustment button 20 to the base body 10, the base body 10 is provided with a through hole 12, and the columnar portion 22 extends into the interior of the base body 10 via the through hole 12 and is connected to the base body 10. The through hole 12 can be an oblong hole arranged along the first direction D1. An example is that, as shown in the embodiment shown in the figure, the columnar portion 22 is connected to the base body 10 through a limiting plate 30. Specifically, a limiting plate 30 is fixed to the top of the columnar portion 22, and the limiting plate 30 abuts against the inner surface of the base body 10 in the up and down direction D3, thereby, through the limiting plate 30, the adjustment button 20 is slidably maintained on the base body 10 to prevent the adjustment button 20 from detaching from the base body 10. The limiting piece 30 can be screwed into the screw hole of the columnar portion 22 along the up-down direction D3 by a fastener such as a screw 41, so that the adjustment button 20, the base body 10 and the limiting piece 30 are assembled together. The limiting piece 30 can move together with the adjustment button 20.
[0072] The base body 10 is provided with a boss 13 protruding upward from its inner bottom surface, the boss 13 extends along the first direction D1, and is respectively provided on both sides of the through hole 12 in the second direction D2. The second direction D2 is perpendicular to both the first direction D1 and the up-down direction D3. The top surface of the boss 13 serves as the inner surface of the base body 10, and is used to abut against the limit plate 30.
[0073] The base body 10 is provided with an adjustment button groove 14 recessed from its lower surface, and the top wall of the adjustment button groove 14 is provided with the above-mentioned air inlet hole and the above-mentioned through hole 12. The adjustment button groove 14 can be an oblong groove arranged along the first direction D1. The operating part 21 of the adjustment button 20 can be located in the adjustment button groove 14 and slidably contact with the top wall of the adjustment button groove 14. In this way, the size of the electronic cigarette base 7 in the up and down direction D3 can be reduced, and the adjustment button 20 does not protrude from the base body 10, which is convenient for the vertical placement of the electronic cigarette 1 and the neat and beautiful appearance.
[0074] like Figure 5 As shown, the adjustment button 20 includes a support member 23 and a sealing member 24 with a sealing rib 25, and the sealing member 24 is located between the support member 23 and the base body 10. The sealing rib 25 protrudes from the upper surface of the sealing member 24 and forms a circle, which can be interference-fitted with the base body 10 to achieve sealing. The sealing member 24 is made of an elastomeric material, such as soft glue, so that the sealing rib 25 can be elastically deformed, and can seal the gap between the adjustment button 20 and the base body 10, ensuring that when the adjustment button 20 is in the suction resistance position, the gas is concentrated to enter from the air inlet 11, and when the adjustment button 20 is in the child lock position, the gas is effectively blocked from entering the interior of the electronic cigarette 1.
[0075] One example is that the sealing member 24 and the support member 23 are integrated by injection molding, for example, by a co-molding process. In this solution, the sealing member 24 and a part of the support member 23 constitute the above-mentioned operating portion 21, and another part of the support member 23 constitutes the above-mentioned columnar portion 22. Another example is that the sealing member 24 is a separate member independent of the support member 23, and in this solution, the support member 23 has the above-mentioned operating portion 21 and the above-mentioned columnar portion 22. The sealing member 24 can be sleeved on the columnar portion 22 and clamped between the operating portion 21 and the base body 10, or adhered to the surface of the operating portion 21.
[0076] Furthermore, in order to make it easy for the adjustment button 20 to switch gears when sliding, the concave portion has an arc-shaped concave surface, and the convex portion has an arc-shaped convex surface. The limit plate 30 has an elastic arm 32 extending in the first direction D1, and the elastic arm 32 can be deformed in the up and down direction D3. The second limit portion 31 is formed at the end of the elastic arm 32, and the first limit portion 15 is located below the elastic arm 32. Preferably, the limit plate 30 is symmetrically provided with elastic arms 32 in the first direction D1 and the second direction D2. At this time, the shape of the limit plate 30 is similar to an H shape, and the center of the limit plate 30 is fixed to the adjustment button 20 by a screw 41. The end of each elastic arm 32 corresponds to the first limit portion 15, forming a gear portion group in different positions. Such a configuration can increase the operational feel of the adjustment button 20 when shifting gears.
[0077] In the illustrated embodiment, each gear position group has one convex portion and three concave portions. Figure 5 As shown, when the adjustment button 20 is in the first suction resistance position, both air inlets are open, the convex portion in each gear portion group is located in the concave portion at the leftmost end, and the sealing rib 25 is located between the through hole 12 and the innermost air inlet. Figure 6 As shown, when the adjustment button 20 is in the second suction resistance position, one of the two air inlets is open and the other is closed, the convex portion in each gear portion group is located in the middle concave portion, and the sealing rib 25 is located between the two air inlets. Figure 7 As shown, when the adjustment button 20 is in the child lock position, the two air inlets are closed, the convex portion in each gear portion group is located in the rightmost concave portion, and the sealing rib 25 is located outside the outermost air inlet hole.
[0078] It should be noted that the directional terms "left" and "right" used here are based on Figures 5 to 7 This is for the electronic cigarette base 7 shown.
[0079] Figure 8 and Fig. 9The base according to the second embodiment of the utility model is shown, and the electronic cigarette base of the second embodiment is described. Except for the related structures such as the stopper 30, the electronic cigarette base of the second embodiment has the same structure and / or construction as the electronic cigarette base 7 of the first embodiment. Therefore, the elements having substantially the same functions as those in the first embodiment will be numbered the same here, and will not be described and / or illustrated in detail for the sake of brevity.
[0080] like Figure 8 and Fig. 9 As shown, the limiting piece 30 can be a hard plastic component. The first limiting portion 15 cooperates with the second limiting portion 31 in the second direction D2 perpendicular to the first direction D1. The first limiting portion 15 is located on the side of the second limiting portion 31 away from its center in the second direction D2. In this scheme, the base body 10 is provided with a boss 13 with a step, so that the boss 13 has a support surface 111 extending in a plane defined by the first direction D1 and the second direction D2 and a gear surface 112 extending in the up and down direction D3. The support surface 111 of the boss 13 serves as the inner surface of the base body 10, and is used to abut against the limiting piece 30. The first limiting portion 15 is formed on the gear surface 112 of the boss 13.
[0081] Exemplarily, the limiting plate 30 is provided with a second limiting portion 31 and an avoidance hole 113 for deformation of the second limiting portion 31 in the middle portion in the first direction D1. The avoidance hole 113 is located on one side of the second limiting portion 31 close to its center in the second direction D2. The second limiting portion 31 can be deformed toward the avoidance hole 113, specifically, the deformable portion between the avoidance hole 113 and the second limiting portion 31 can be deformed toward the avoidance hole 113. The avoidance hole 113 is an elongated hole arranged in the first direction D1, and correspondingly, the deformable portion is an elongated strip. The limiting plate 30 in this scheme is roughly rectangular in shape.
[0082] In the illustrated embodiment, the first limit portion 15 is a concave portion, and the second limit portion 31 is a convex portion. Of course, if necessary and / or desired, the first limit portion 15 is a convex portion, and the second limit portion 31 is a concave portion. The first limit portion 15 and the second limit portion 31 are symmetrically arranged in the second direction D2, and each second limit portion 31 corresponds to an avoidance hole 113. Optionally, there is one convex portion and three concave portions in each gear portion group.
