[0036] To solve the related technical problems, as shown in Figures 1 to 3 The base structure of the electronic cigarette provided by the embodiment of the present application comprises:

[0037] a seat body 50;

[0038] a mounting member 52, the mounting member 52 being used for mounting an electric control assembly, the mounting member 52 being arranged on the seat body 50;

[0039] a shell 51, the shell 51 being sleeved on the mounting member 52 and the seat body 50 to connect the mounting member 52 and the seat body 50;

[0040] The seat body 50 is provided with a plurality of first plug-in portions 502, the mounting member 52 is provided with a plurality of second plug-in portions 520, the first plug-in portions 502 correspond to the second plug-in portions 520 in up and down directions, and the inner side of the shell 51 is provided with a plurality of third plug-in portions 510, the third plug-in portions 510 being plug-in matched with the first plug-in portions 502 and the second plug-in portions 520.

[0041] In the embodiment, the base structure 5 mainly comprises the seat body 50, the mounting member 52 and the shell 51. The seat body 50 serves as a mounting base and can mount power supply elements such as batteries. The mounting member 52 can be assembled to the seat body 50 after mounting the electric control assembly. In the embodiment, the electric control elements include circuit boards, electrodes for connecting with atomizers and other electronic components. The shell 51 serves as a housing and can be sleeved on the mounting member 52 and the seat body 50. The shell 51 serves as a protective structure for the batteries on the seat body 50 and the electric control assembly on the mounting member 52, and also improves the appearance of the product. In the embodiment, the mounting member 52 can be mounted to the upper end of the seat body 50, and the shell 51 can be sleeved on the mounting member 52 and the seat body 50 from top to bottom. In order to facilitate the assembly of the seat body 50, the mounting member 52 and the shell 51, the first plug-in portions 502 are arranged on the seat body 50, the second plug-in portions 520 are arranged on the mounting member 52, and the third plug-in portions 510 are arranged on the shell 51.

[0042] In the assembly, the shell 51 can be sleeved on the base body 50, and the first plug-in part 502 and the third plug-in part 510 are plug-in matched, and then the mounting part 52 is sleeved in the shell 51, and the second plug-in part 520 and the third plug-in part 510 are plug-in matched. Alternatively, after the mounting part 52 and the base body 50 are aligned, the shell 51 is directly sleeved on the mounting part 52 and the base body 50, and the third plug-in part 510 is synchronously plug-in matched with the first plug-in part 502 and the second plug-in part 520, so that the quick assembly of the base body 50, the mounting part 52 and the shell 51 is completed, thereby realizing the technical effect that the main mounting parts can be quickly and conveniently assembled in the assembly process of the base, and further solving the problems that the connection structure between the main mounting parts of the electronic cigarette base in the related art is relatively complex and the assembly time is relatively long.

[0043] When the assembly mode of aligning the base body 50 and the mounting part 52 is adopted, corresponding pre-connection structures can be arranged on the base body 50 and the mounting part 52, for example, a groove is arranged at the upper end of the base body 50, and a protrusion is arranged at the lower end of the mounting part 52, so that the pre-connection is realized by plug-in matching of the protrusion and the groove.

[0044] In addition, in the embodiment, the second plug-in part 520 and the first plug-in part 502 can correspond to each other in the up-down direction, and at this time, the third plug-in part 510 can be a strip-shaped structure formed on the inner side of the shell 51. When the second plug-in part 520 and the first plug-in part 502 are misaligned, the third plug-in part 510 includes a part plug-in matched with the first plug-in part 502 and a part plug-in matched with the second plug-in part 520, and the two parts are also misaligned. In order to facilitate processing and forming, as shown in Figure 2 and Figure 3 In the embodiment, it is preferred that the second plug-in part 520 and the first plug-in part 502 correspond to each other in the up-down direction, and the third plug-in part 510 is a complete strip-shaped structure formed on the inner side of the shell 51.

[0045] In one embodiment of the plug-in part, the first plug-in part 502 can be a protrusion structure or a slot structure formed on the base body 50, the second plug-in part 520 can also be a protrusion structure or a slot structure formed on the mounting part 52, and the third plug-in part 510 can also be a protrusion structure or a slot structure formed in the shell 51. Since the shell 51 is generally thin, it is difficult to form a slot structure that meets the connection requirements, and therefore in the embodiment, the third plug-in part 510 is preferably a slot structure formed in the shell 51.

[0046] Specifically, as shown in Figure 2 and Figure 3As shown, the first plug-in part 502 is a first plug-in slot 5020 opened on the seat body 50, the second plug-in part 520 is a second plug-in slot 5200 opened on the mounting member 52, the second plug-in slot 5200 corresponds to the first plug-in slot 5020 up and down, and the third plug-in part 510 is a plug-in protrusion 5100 formed on the inner side of the shell 51, which is plugged and matched with the first plug-in slot 5020 and the second plug-in slot 5200.

[0047] In an embodiment of the plug-in protrusion 5100, the plug-in protrusion 5100 can be provided as a strip structure with a rectangular cross section, or a strip structure with a semicircular arc-shaped end. In order to improve the stability of the connection, the structure of the plug-in protrusion 5100 is further adjusted in the embodiment, and specifically, as shown in the figure, Figure 3 the plug-in protrusion 5100 in the embodiment includes a first convex segment 51001 and a second convex segment 51002 connected in sequence from the outside to the inside, the first convex segment 51001 is connected with the inner side of the shell 51, and the cross section of the second convex segment 51002 is provided as a circular arc, and the arc length is greater than one-half of the arc length of a whole circle;

[0048] The first plug-in slot 5020 includes a first slot segment that is plugged and matched with the second convex segment 51002, and the second plug-in slot 5200 includes a second slot segment that is plugged and matched with the second convex segment 51002.

[0049] In the embodiment, the cross section of the second convex segment 51002 of the plug-in protrusion 5100 is provided as a circular arc, and the arc length is greater than one-half of the arc length of a whole circle, so that a section of the second convex segment 51002 towards the shell 51 is inwardly contracted. When the first plug-in slot 5020 includes a first slot segment that is plugged and matched with the second convex segment 51002, and the second plug-in slot 5200 includes a second slot segment that is plugged and matched with the second convex segment 51002, the second convex segment 51002 can apply an outward pulling force to the mounting member 52 and the seat body 50 when plugged and matched with the first slot segment and the second slot segment, thereby achieving the connection of the seat body 50 and the mounting member 52, preventing the displacement between the seat body 50 and the mounting member 52, and improving the stability of the connection.

[0050] In order to better include the internal battery and electronic control components, the outer side of the seat body 50 and the outer side of the mounting member 52 should be matched with the inner side of the shell 51. Therefore, after the plug-in protrusion 5100 includes the second convex segment 51002, in order to facilitate the plug-in matching during assembly, as shown in the figure, Figure 3 the cross section of the first convex segment 51001 in the embodiment includes two connecting surfaces connected to the two sides of the second convex segment 51002, the connecting surfaces are connected with the inner side of the shell 51, and the spacing between the two connecting surfaces gradually increases from the inside to the outside; the first plug-in slot 5020 includes a third slot segment that is plugged and matched with the connecting surfaces, and the second plug-in slot includes a fourth slot segment that is matched with the connecting surfaces.

[0051] Specifically, in the embodiment, the cross section of the first convex section 51001 is a triangular structure, which not only increases the structural strength between the second convex section 51002 and the shell 51, but also facilitates the plug-in cooperation between the plug-in protrusion 5100 and the corresponding plug-in slot. In addition, the setting of the first convex section 51001 also increases the structural strength of the shell 51 at the position where the plug-in protrusion 5100 is arranged, which can avoid the tensile deformation of the thin shell 51 during assembly.

[0052] In another embodiment, the cross section of the first convex section 51001 includes a connecting surface connected to the two sides of the second convex section 51002, the connecting surface is connected to the inner side of the shell 51, and the connecting surface is arranged as an outward convex arc surface, and the distance between the vertices of the two sides of the connecting surface is greater than the diameter of the second convex section 51002.

[0053] Specifically, in the embodiment, the connecting surface is arranged as an arc surface, so that the cross section of the plug-in protrusion 5100 is a gourd-shaped shape. The structure of the first convex section 51001 in the embodiment is similar in function to the structure of the first convex section 51001 in the above-mentioned embodiment. However, since there is a small included angle between the first convex section 51001 and the shell 51, the difficulty in processing is increased. Therefore, in the utility model, it is preferred to adopt a triangular structure for the cross section of the first convex section 51001.

[0054] In one embodiment of the seat body 50, as shown in Figures 1 to 3 The shell 51 is provided with a mounting slot 511 which is plug-in cooperated with the boss 501, and the lower end of the mounting slot 511 is an open structure, which makes the mounting slot 511 plug-in cooperated with the boss 501. The boss 501 can be configured with a display screen, a control button and the like of the electronic cigarette, which is not limited in the embodiment. In the embodiment, the first plug-in part 502 is located at least on both sides of the boss 501, and the second plug-in part 520 and the third plug-in part 510 are one by one corresponding to the first plug-in part 502, and the third plug-in part 510 is located at least on both sides of the mounting slot 511, so as to not only ensure the connection stability, but also strengthen the structural strength of the shell 51 near the mounting slot 511, and avoid tensile deformation during assembly.

[0055] As shown in Figure 2As shown, when the assembly process adopts the assembly mode of first installing the seat body 50 into the shell 51, and then installing the mounting piece 52 into the shell 51, in order to facilitate the connection of the first plug-in groove 5020 and the plug-in protrusion 5100, and the second plug-in groove 5200 and the plug-in protrusion 5100, a first lead-in inclined surface 504 is arranged at the upper end of the first plug-in groove 5020 in the embodiment, and the first lead-in inclined surface 504 is a necked surface extending downward; similarly, a second lead-in inclined surface 521 is arranged at the lower end of the second plug-in groove 5200, and the second lead-in inclined surface 521 is a necked surface extending upward.

[0056] In order to facilitate the limiting of the shell 51 during the assembly process, a flange 503 is arranged at the lower part of the seat body 50, and the lower end of the shell 51 abuts against the flange 503.

[0057] In an embodiment of the seat body 50, the mounting piece 52 and the shell 51, the seat body 50 and the mounting piece 52 are arranged as plastic parts, and the shell 51 is arranged as a metal part.

[0058] According to another aspect of the present application, as shown in the accompanying drawings, Figure 5 As shown, an electronic cigarette is provided, which comprises an atomizer and the above-mentioned base structure 5, and the atomizer is fixed on the base structure 5 or detachably connected with the base structure 5.

[0059] According to another aspect of the present application, as shown in the accompanying drawings, Figure 4 As shown, an atomizer is provided, which comprises:

[0060] The atomizer main body 1 is internally provided with an atomizing core 10;

[0061] The suction nozzle 2 is fixedly arranged on the atomizer main body 1, and the suction nozzle 2 is internally provided with an air pipe 20, the lower end of the air pipe 20 corresponds to the atomizing gas outlet 100 of the atomizing core 10, and the lower end surface of the air pipe 20 is provided with a plurality of first condensation grooves 201 arranged as through grooves penetrating the side wall of the suction nozzle 2;

[0062] The bracket 4 is arranged on the atomizer main body 1, and the bracket 4 is provided with a mounting hole, and the upper end of the atomizing core 10 extends into the mounting hole;

[0063] The condensate adsorption pad 3 is arranged on the bracket 4 and between the air pipe 20 and the atomizing gas outlet 100, and the condensate adsorption pad 3 is provided with a through air hole 30, and the two ends of the through air hole 30 correspond to the lower end of the air pipe 20 and the atomizing gas outlet 100 respectively;

[0064] The diameter of the through air hole 30 is greater than the inner diameter of the air pipe 20, a part of the upper end surface of the first condensation groove 201 is opposite to the condensate adsorption pad 3, and another part is opposite to the through air hole 30.

[0065] In the embodiment, the atomizer body 1 comprises an atomization cavity and an atomization core 10, a part of the atomization core 10 is located in the atomization cavity, the atomization cavity can store tobacco tar, the atomization core 10 can heat and atomize the tobacco tar, and the atomized gas is discharged from the atomization gas outlet 100 at the upper end of the atomization core 10. In the embodiment, the specific structure and layout of the atomization core 10 and the atomizer body 1 can adopt the structure of the atomizer in the related art, which will not be described here in detail.

[0066] The suction nozzle 2 is fixed at the upper end of the atomizer body 1, and specifically, the suction nozzle 2 can be fixed by buckling, or welded after being inserted, etc. The air pipe 20 is arranged in the suction nozzle 2, and the air pipe 20 can be integrally formed with the suction nozzle 2, or be a tubular structure installed in the suction nozzle 2. The lower end of the air pipe 20 corresponds to the atomization core 10 and extends towards the atomization core 10. The atomized gas discharged from the atomization gas outlet 100 of the atomization core 10 enters the air pipe 20. Since the temperature of the air pipe 20 is lower than the temperature of the atomized gas, the wet and hot atomized gas is easy to form condensate on the inner surface of the air pipe 20 after contacting the air pipe 20, and the condensate flows downward along the inner wall of the air pipe 20.

[0067] In order to reduce the downward flow of the condensate into the atomization core 10, a bracket 4 is arranged at the upper end of the atomizer body 1 in the embodiment, the bracket 4 is provided with a mounting hole, and the upper end of the atomization core 10 is inserted into the mounting hole. The condensate adsorption pad 3 is arranged on the bracket 4, and the condensate adsorption pad 3 is made of a material with liquid adsorption capacity, such as sponge or other porous adsorption material. The condensate adsorption pad 3 is located between the air pipe 20 and the atomization core 10, and in order to facilitate the passage of the atomized gas, the condensate adsorption pad 3 is provided with a gas passage hole 30, and the two ends of the gas passage hole 30 correspond to the air pipe 20 and the atomization gas outlet 100 respectively.

[0068] After arranging the condensate adsorption pad 3, in order to reduce the backflow of the condensate into the atomization core 10, the diameter of the gas passage hole 30 on the condensate adsorption pad 3 is greater than the inner diameter of the air pipe 20 in the embodiment, and a plurality of first condensate grooves 201 are arranged on the lower end surface of the air pipe 20, and a part of the upper end surface of the first condensate groove 201 is opposite to the condensate adsorption pad 3, and the other part is opposite to the gas passage hole 30. That is, in the embodiment, the diameter of the gas passage hole 30 is smaller than the outer diameter of the air pipe 20 and greater than the inner diameter of the air pipe 20, so that the first condensate groove 201 is opposite to the upper end surface of the condensate adsorption pad 3 and the edge region of the gas passage hole 30.

[0069] Since the diameter of the ventilation hole 30 is also larger than the diameter of the atomizing gas outlet 100, the atomizing gas discharged through the atomizing gas outlet 100 diffuses into the ventilation hole 30, contacts the upper end surface of the first condensate groove 201 after flowing upward, and forms condensate on the upper end surface of the first condensate groove 201. This part of the condensate drops onto the condensate adsorption pad 3 and is finally adsorbed by the condensate adsorption pad 3. After the first condensate groove 201 is opened at the lower end of the air tube 20, the area of the inner vertical surface of the air tube 20 is reduced, the upper end surface of the first condensate groove 201 is opposite to the flow direction of the atomizing gas, and it is easier to form condensate on the upper end surface of the first condensate groove 201. The amount of condensate formed on the inner vertical surface of the air tube 20 is reduced, more condensate is formed on the upper end surface of the first condensate groove 201 and is adsorbed by the condensate adsorption pad 3, thereby reducing the condensate flowing back into the atomizing core 10, improving the atomization effect of the tobacco tar in the atomizing core 10 and the taste, and further solving the problem in the related art that the condensed liquid from the suction nozzle 2 of the atomizer easily flows back into the atomizing core 10, affecting the subsequent atomization effect of the tobacco tar and the taste.

[0070] In addition, since the first condensate groove 201 in the embodiment is a through groove penetrating the side wall of the air tube 20, the atomizing gas entering the air tube 20 can flow to the outside of the air tube 20 through the first condensate groove 201, thereby improving the heat dissipation effect of the atomizing gas.

[0071] In an embodiment, as shown in Figure 4 the outer wall of the air tube 20 and the inner wall of the suction nozzle 2 have a cavity, and the upper end of the condensate adsorption pad 3 corresponds to the cavity after the suction nozzle 2 is installed. The atomizing gas entering the air tube can flow from the first condensate groove 201 to the cavity, thereby significantly increasing the heat dissipation effect of the atomizing gas. Since the upper end of the condensate adsorption pad 3 corresponds to the cavity, the condensate formed on the inner wall of the cavity can also be adsorbed by the condensate adsorption pad 3.

[0072] On the basis of the above-mentioned embodiments, in order to further prevent the condensate from entering the atomizing core 10, a plurality of second condensate grooves 202 are arranged on the inner side of the air tube 20 in the embodiment. The second condensate groove 202 corresponds to the first condensate groove 201, the lower end of the second condensate groove 202 communicates with the corresponding first condensate groove 201, and the radial depth of the second condensate groove 202 is smaller than the radial depth of the first condensate groove 201.

[0073] The upper end of the second condensate groove 202 corresponds to the ventilation hole 30.
