Detailed implementation manners

[0028] Next, the solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, top, bottom, side...) in the following embodiments are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0030] It should also be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0031] In addition, the descriptions involving "first", "second", etc. in the following embodiments are for descriptive purposes only, and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features.

[0032] In view of the technical deficiencies existing in the related art, this embodiment provides an electronic cigarette. As Figure 1 shown, the electronic cigarette of this embodiment includes an atomizing device A and a power supply device B for supplying power to the atomizing device A.

[0033] As Figure 2 shown, the atomizing device A of this embodiment includes an atomizing member 100 and an oil storage bottle 200.

[0034] The atomizing member 100 includes an atomizing portion 110 and a mouthpiece 120 connected to the atomizing portion 110. An atomizing cavity for accommodating an atomizing matrix such as e-liquid is formed in the atomizing portion 110. An atomizer 130 communicated with the mouthpiece 120 is arranged in the atomizing cavity, and the atomizer 130 is used for converting the atomizing matrix in the atomizing cavity into aerosol, so that a user can inhale the aerosol through the mouthpiece 120.

[0035] Continuing to refer to Figure 2 and Figure 3 shown, a connection hole 102 is formed on the side of the atomizing portion 110 facing away from the mouthpiece 120. The connection hole 102 is arranged in a staggered manner with the mouthpiece 120, that is, the connection area between the mouthpiece 120 and the atomizing portion 110 cannot be observed through the connection hole 102. Among them, the connection hole 102 is communicated with the atomizing cavity, and an oil guiding convex member 140 is arranged in the connection hole 102. In an alternative example, the oil guiding convex member 140 can be connected to the hole wall of the connection hole 102 through a support arm, so as to be suspended in the connection hole 102; in another alternative example, the oil guiding convex member 140 can be arranged in the area of the inner surface of the atomizing cavity opposite to the connection hole 102 and extend into the connection hole 102.

[0036] Continuing to refer to Figure 2 and Figure 3 shown, the oil storage bottle 200 of this embodiment includes a housing 210 for accommodating an atomizing matrix and a connecting pipe 220 communicated with the inner cavity of the housing 210. The pipe orifice of the connecting pipe 220 is sealed by a sealing film. Exemplarily, the sealing film can be made of materials such as aluminum-plastic film or tin foil, but is not limited thereto. Any thin film material with better sealing performance and easy to be punctured can be used to prepare the sealing film of this embodiment.

[0037] Continuing to combine Figure 3 and Figure 4As shown in the figure, under the action of an external force, the connecting pipe 220 can be inserted into the connecting hole 102 to splice the atomizing member 100 and the oil storage bottle 200. Among them, during the process of inserting the connecting pipe 220 into the connecting hole 102, the sealing film is punctured by the oil guiding convex member 140 to communicate the inner cavity of the storage cavity 210 and the atomizing cavity. After splicing the atomizing member 100 and the oil storage bottle 200, tilting the entire atomizing device A can cause the atomizing matrix in the storage cavity 210 to flow into the atomizing cavity in sequence through the connecting pipe 220 and the connecting hole 102.

[0038] Compared with the related art, the atomizing device A of the electronic cigarette in this embodiment is constructed as an independent structure that can be detachably connected to the power supply device B. Therefore, when the atomizing device A is contaminated, only the atomizing device A itself needs to be replaced, and there is no need to purchase a new electronic cigarette. In addition, the atomizing member 100 and the oil storage bottle 200 of the atomizing device A are of a spliceable structure, thus facilitating the replacement operation of the atomizing member 100 and the oil storage bottle 200.

[0039] In addition, as Figure 3 shown, in order to increase the capacity of the oil storage bottle 200, the oil storage bottle 200 in this embodiment is cylindrical. Therefore, after the atomizing member 100 and the oil storage bottle 200 are spliced, the oil storage bottle 200 protrudes from the atomizing member 100. For this reason, the power supply device B in this embodiment has a profiling groove C for inserting and matching the above atomizing device A, so as to improve the matching degree between the atomizing device A and the power supply device B and improve the flatness of the overall electronic cigarette.

[0040] In some embodiments, as Figure 3 shown, the atomizing part 110 includes a top wall 111 and a bottom wall 112 arranged opposite to each other and a side wall 113 connecting the top wall 111 and the bottom wall 112. The top wall 111, the bottom wall 112 and the side wall 113 enclose to form an atomizing cavity. In this embodiment, the mouthpiece 120 is connected to the side of the top wall 111 facing away from the bottom wall 112.

[0041] To facilitate the installation of the atomizer 130, a first installation hole 103 is opened on the bottom wall 112 and is arranged opposite to the mouthpiece 120, and the first installation hole 103 communicates with the atomizing cavity. Among them, the connecting hole 102 is also opened on the bottom wall 112, and the connecting hole 102 is arranged adjacent to the first installation hole 103.

[0042] Since the connecting hole 102 is arranged offset from the mouthpiece 120, the connection area between the mouthpiece 120 and the top wall 111 cannot be observed through the connecting hole 102. And the first installation hole 103 is arranged opposite to the mouthpiece 120, so the connection area between the mouthpiece 120 and the top wall 111 can be observed through the first installation hole 103.

[0043] In this embodiment, the atomizing part 110 further includes a sealing seat 150 for sealing the first mounting hole 103. On the side of the sealing seat 150 facing away from the top wall 111, there are provided a plurality of first electrodes electrically connected to the atomizer 130 and a first magnetic attracting member. During the assembly process, the atomizer 130 can be first inserted into the atomizing cavity through the first mounting hole 103, then the first electrodes on the atomizer 130 and the sealing seat 150 are connected, and finally the first mounting hole 103 is sealed by the sealing seat 150.

[0044] Continuing with reference to Figure 5 As shown, in the profiling groove C of the power supply device B, there are provided a second electrode corresponding to the first electrode and a second magnetic attracting member corresponding to the first magnetic attracting member. When the atomizing device A of this embodiment is inserted and mated with the power supply device B, the first electrode contacts the second electrode, so that the power supply device B can supply power to the atomizer 130. And the first magnetic attracting member and the second magnetic attracting member adsorb each other to prevent the atomizing device A from detaching from the power supply device B.

[0045] Furthermore, the sealing seat 150 includes a bottom cover 151 and an upper cover 152. The bottom cover 151 is detachably connected to the first mounting hole 103, and the upper cover 152 is disposed on the side of the bottom cover 151 facing the top wall 111. A first air hole 104 is formed in the bottom cover 151, and a second air hole 105 communicating with the first air hole 104 is formed in the upper cover 152. Among them, the first electrodes and the first magnetic attracting member are disposed on the side of the bottom cover 151 facing away from the upper cover 152. Exemplarily, a sealing flange is provided on the periphery of the upper cover 152, and the upper cover 152 forms an interference fit with the hole wall of the first mounting hole 103 through the sealing flange to prevent the atomizing matrix from leaking outwards.

[0046] The atomizer 130 includes an atomizing tube 131 and an atomizing core 132. One end of the atomizing tube 131 is connected to the mouthpiece 120, and the other end of the atomizing tube 131 is connected to the upper cover 152. The second air hole 105 and the mouthpiece 120 are communicated with each other through the atomizing tube 131. An oil inlet hole 106 is formed in the atomizing tube 131, the atomizing core 132 is disposed in the atomizing tube 131 and shields the oil inlet hole 106, and the atomizing core 132 is electrically connected to the first electrode through a wire. It can be understood that when the atomizing device A and the power supply device B are inserted and mated, the first air hole 104 is also communicated with the air inlet channel and the negative pressure channel of the power supply device B, so that when the user sucks the mouthpiece 120, the microphone is triggered through the negative pressure channel, and then the battery module of the power supply device B supplies power to the atomizing core 132.

[0047] An oil storage cotton 160 is further disposed in the atomization cavity. The oil storage cotton 160 is sleeved on the atomization tube 131 and shields the oil inlet hole 106. When the atomization matrix flows into the atomization cavity, the atomization matrix will be absorbed by the oil storage cotton 160. On the one hand, the oil storage cotton 160 plays a role in storing oil. When the atomization device A is placed upright, it can also ensure that a part of the atomization matrix remains in the atomization cavity for the atomizer 130 to generate aerosol. On the other hand, the oil storage cotton 160 also plays a role in locking oil, thereby slowing down the amount of e-liquid flowing into the atomization core 132 to prevent the atomization core 132 from being overly wetted by e-liquid and reducing the gurgling sound generated when using the electronic cigarette. According to actual needs, the oil storage cotton 160 can fill all or part of the space of the atomization cavity.

[0048] In some embodiments, as Figure 3 shown, a second mounting hole 107 is formed on the top wall 111 and is arranged opposite to the connection hole 102. The second mounting hole 107 is communicated with the connection hole 102. That is to say, the connection hole 102 can be observed through the second mounting hole 107. In this embodiment, the atomization part 110 further includes a sealing cover 170 for sealing the second mounting hole 107. The oil guiding protrusion 140 is disposed on the side of the sealing cover 170 facing the connection hole 102 and extends into the connection hole 102, thereby facilitating the installation of the oil guiding protrusion 140. Exemplarily, the sealing cover 170 can form a detachable connection with the top wall 111, such as a snap connection or the like; the sealing cover 170 can also form a detachable connection with the hole wall of the second mounting hole 107, such as a threaded connection or the like. When the atomization matrix in the oil storage bottle 200 is exhausted, in addition to directly replacing another oil storage bottle 200, the sealing cover 170 can be disassembled and new atomization matrix can be directly injected into the oil storage bottle 200 through the second mounting hole 107.

[0049] In some embodiments, as Figure 2 shown, a step is formed on the side of the atomization part 110 facing away from the mouthpiece 120, that is, a step is formed on the bottom wall 112. The step has a first step surface 100a and a second step surface 100b. The first step surface 100a is arranged opposite to the mouthpiece 120, and the second step surface 100b is arranged offset from the mouthpiece 120. In the axial direction of the suction hole of the mouthpiece 120, the distance from the first step surface 100a to the mouthpiece 120 is greater than the distance from the second step surface 100b to the mouthpiece 120. Among them, the connection hole 102 is formed on the second step surface 100b, and the first mounting hole 103 is formed on the first step surface 100a. When the atomization component 100 and the oil storage bottle 200 are spliced, at least part of the oil storage bottle 200 can be received in the step, thereby reducing the protrusion degree of the oil storage bottle 200 and improving the flatness of the atomization device A.

[0050] The above are only some or preferred embodiments of the present utility model. Neither the text nor the drawings can limit the scope of protection of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the concept of an integral whole of the present utility model, or any direct / indirect application in other related technical fields, is included in the scope of protection of the present utility model.
