Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0033] In order to solve the technical problem in the prior art that the cigarette rod body 200 shakes relative to the cigarette rod holder 100 and causes poor electrical contact between the two, the present application provides an electronic cigarette, a cigarette rod assembly and a cigarette rod holder 100, which can improve the reliability of the installation and fixation of the cigarette rod holder 100 to the cigarette rod body 200 and maintain good electrical contact between the cigarette rod holder 100 and the cigarette rod body 200.

[0034] It should be noted that this application mainly improves the structure of the bracket housing 10 of the cigarette rod bracket 100 and the assembly relationship with the cigarette rod body 200. The circuit board, battery, charging port and conductive needle set in the cigarette rod bracket 100 are not improved. The specific settings and working processes can refer to the existing technology, and this application will not be described in detail. In addition, the atomizer core of the cigarette rod body 200 and the connecting pins for connecting the atomizer core to the conductive pins to achieve electrical connection between the cigarette rod body 200 and the cigarette rod bracket 100 are also unchanged.

[0035] The structure of the cigarette rod support 100 provided in the embodiment of the present application can be referred to Figures 1 to 3 The cigarette rod support 100 includes a support housing 10, and the support housing 10 defines a mounting cavity 13, the shape of which matches the shape of the cigarette rod body 200, and is used for inserting the cigarette rod body 200 and fixing the cigarette rod body 200. After the cigarette rod body 200 is inserted into the mounting cavity 13, the mounting cavity 13 and the cigarette rod body 200 are positioned in cooperation to achieve electrical connection between the cigarette rod body 200 and the cigarette rod support 100.

[0036] In order to improve the reliability of supporting and fixing the cigarette rod body 200, the bracket housing 10 is further provided with a flexible positioning part, which is protruded relative to the inner wall of the installation cavity 13. When the cigarette rod body 200 is installed in the installation cavity 13, the end portion of the flexible positioning part extending toward the axis of the installation cavity 13 abuts against the outer wall of the cigarette rod body 200, thereby forming a certain interference fit with the cigarette rod body 200, improving the reliability of supporting and fixing the cigarette rod body 200, effectively preventing the cigarette rod body 200 from shaking relative to the bracket housing 10 and the cigarette rod bracket 100, and thus ensuring that after the cigarette rod body 200 is inserted into the installation cavity 13, the atomizer core inside it and the battery inside the cigarette rod bracket 100 are kept in good electrical connection.

[0037] The setting of the flexible fixing part allows the fitting clearance between the mounting cavity 13 and the cigarette rod body 200 to be appropriately adjusted under the premise of ensuring the stability of the support and positioning of the cigarette rod body 200; at the same time, the setting of the flexible fixing part can effectively prevent the cigarette rod body 200 from colliding with the inner wall of the mounting cavity 13 when it is installed into the cigarette rod holder 100 or removed from the mounting cavity 13 of the cigarette rod holder 100, thereby damaging the outer wall surface of the cigarette rod body 200.

[0038] In some embodiments, Figures 2 to 4As shown, the bracket housing 10 includes an inner shell 11 and an outer shell 12, the inner shell 11 is generally cylindrical, the outer shell 12 is sleeved and connected to the outer periphery of the inner shell 11, the installation cavity 13 is opened in the inner shell 11, and the inner shell 11 has a positioning hole. Among them, the positioning hole passes through from the outer wall of the inner shell 11 to the installation cavity 13 along the radial direction of the inner shell 11. The cigarette rod bracket 100 also includes a silicone sleeve 14 arranged between the inner shell 11 and the outer shell 12, and the flexible positioning part can be a silicone protrusion 15 made of silicone material, and the silicone protrusion 15 is connected to the silicone sleeve 14.

[0039] When the silicone sleeve 14 is sleeved and connected to the outer periphery of the inner shell 11, the silicone protrusion 15 passes through the inner shell 11 from the positioning hole on the inner shell 11 and extends to the installation cavity 13, so that the end of the silicone protrusion 15 is protruded relative to the inner wall of the inner shell 11. After the cigarette rod body 200 is inserted into the bracket shell 10 or the installation cavity 13 of the cigarette rod bracket 100, the outer wall of the cigarette rod body 200 squeezes the end of the silicone protrusion 15, so that the silicone protrusion 15 undergoes a certain elastic deformation and forms an interference fit with the cigarette rod body 200, thereby improving the stability of supporting and fixing the cigarette rod body 200.

[0040] It is understood that the flexible positioning portion is not limited to the form of the silicone protrusion 15 in the above embodiment, and can also be a flexible positioning ring arranged on the inner wall of the installation cavity 13. Exemplarily, an annular groove is provided on the inner wall of the inner shell 11, and the flexible positioning ring is embedded in the annular groove. After the flexible positioning ring is embedded in the annular groove on the inner wall of the inner shell 11, the flexible positioning ring is protruded relative to the inner wall of the inner shell 11 / installation cavity 13.

[0041] The flexible positioning ring is made of a soft material with a certain elastic deformation ability, such as silicone or rubber material, to ensure stable support for the cigarette rod body 200 inserted into the installation cavity 13, while effectively preventing the outer wall surface of the cigarette rod body 200 from being scratched. In order to facilitate the installation and replacement of the flexible positioning ring, the inner shell 11 and the outer shell 12 can adopt a detachable assembly structure, and the inner shell 11 is preferably set as a split structure that can be spliced ​​and matched, so that after the inner shell 11 is opened, the flexible positioning ring on the inner wall of the inner shell 11 can be installed or replaced.

[0042] Furthermore, in order to prevent the silicone sleeve 14 from moving along the axial direction of the inner shell 11, the end of the silicone protrusion 15 is pulled back into the positioning hole or even pulled out of the positioning hole, which affects the support and fixation of the silicone protrusion 15 to the cigarette rod body 200, a first annular positioning groove is also provided on the outer periphery of the inner shell 11. The first annular positioning groove is located in the middle section of the inner shell 11 in the axial direction, and the positioning hole is opened at the bottom of the first annular positioning groove and penetrates to the installation cavity 13. The silicone sleeve 14 is installed in the first annular positioning groove, and the silicone sleeve 14 is axially limited by the first annular positioning groove to ensure that the silicone protrusion 15 always remains in a state of protruding relative to the inner wall of the inner shell 11 or the installation cavity 13.

[0043] In some embodiments, the outer shell 12 is in the form of a split setting, which is convenient for opening and separating from the inner shell 11, and then facilitating the assembly of the silicone sleeve 14 and the silicone protrusion 15 with the inner shell 11. The outer shell 12 can be set as two parts that can be opened and closed. When the outer shell 12 is opened, the inner shell 11 can be removed to replace the flexible fixing part. After the outer shell 12 is closed, the inner shell 11 and the silicone sleeve 14 embedded in the outer wall are fixed and protected.

[0044] Exemplarily, the outer shell 12 includes a first subshell 121 and a second subshell 122. The first subshell 121 and the second subshell 122 can be rectangular shells or semi-cylindrical shells. The first ends of the first subshell 121 and the second subshell 122 are rotatably connected by a rotating shaft, and the second ends of the first subshell 121 and the second subshell 122 are respectively provided with mutually matching buckles and slots, and the second ends of the two are buckled and connected by the buckle and slot.

[0045] The first sub-shell 121 is provided with a first half cavity, and the second sub-shell 122 is provided with a second half cavity. After the first sub-shell 121 and the second sub-shell 122 are snap-fitted together, the first half cavity and the second half cavity are spliced ​​to form a positioning cavity, and the inner shell 11 and the silicone sleeve 14 sleeved on its outer wall are installed in the positioning cavity, that is, the outer shell 12 fixes the inner shell 11 and the silicone sleeve 14 through the positioning cavity on its inner wall.

[0046] The outer shell 12 is not limited to the two-part structure of the first sub-shell 121 and the second sub-shell 122 in the above embodiment, and can also be set as a structure of three or more sub-shells spliced ​​together as needed, as long as it can fix and protect the inner shell 11 and the silicone sleeve 14, it is applicable to the present application. The first sub-shell 121 and the second sub-shell 122 are also not limited to the method in the above embodiment in which one end is connected by a rotating shaft and the other end is connected by snapping. Both ends of the first sub-shell 121 and the second sub-shell 122 can also be set as a structure of snap-fit ​​connection or connection by fasteners. The positioning cavity composed of the first half cavity and the second half cavity matches the shape of the inner shell 11 and the silicone sleeve 14, and the outer shell 12 is assembled and fixed by the positioning cavity and the inner shell 11 and the silicone sleeve 14 in the form of interference fit.

[0047] Further reading Figure 2 and Figure 3 In order to improve the reliability of fixing the cigarette rod body 200 , multiple groups of flexible positioning parts can be arranged along the axial direction of the inner wall of the installation cavity 13 , or multiple groups of flexible positioning parts can be evenly arranged along the circumferential direction of the inner wall of the installation cavity 13 .

[0048] Figure 2 In the embodiment, two groups of flexible positioning parts are arranged axially along the inner wall of the mounting cavity 13. In a specific implementation, the flexible positioning parts can also be arranged in three groups or more. By means of arranging multiple groups of flexible positioning parts axially alternately along the inner wall of the mounting cavity 13, the coaxiality of the cigarette rod body 200 with the mounting cavity 13 can be improved after the cigarette rod body 200 is installed in the mounting cavity 13. At the same time, the cigarette rod body 200 can be supported at multiple positions along the axial direction of the cigarette rod body 200, thereby improving the reliability of the support and fixation and effectively reducing the shaking of the cigarette rod body 200.

[0049] Figure 3 In the embodiment, the flexible positioning part adopts silicone protrusions 15, and the silicone protrusions 15 are evenly arranged in six groups along the circumference of the inner wall of the installation cavity 13, so as to realize multi-point support of the cigarette rod body 200 along the circumference of the inner wall of the installation cavity 13, and prevent the cigarette rod body 200 from deviating to any inner wall of the installation cavity 13. In specific implementation, the silicone protrusions 15 can also be arranged in other groups, and can be evenly arranged along the circumference of the inner wall of the installation cavity 13, or can be unevenly arranged, and this application does not make specific restrictions on this.

[0050] The installation cavity 13 is provided with an insertion port, and the cigarette rod body 200 can be inserted and fixed into the installation cavity 13 from the insertion port. In some embodiments, in order to facilitate the insertion of the cigarette rod body 200 into the installation cavity 13 and to facilitate the removal from the installation cavity 13, and to reduce the resistance of the flexible positioning part to the cigarette rod body 200 along the axial direction of the installation cavity 13, a guiding inclined surface is provided at the end of the flexible positioning part for abutting against the cigarette rod body 200. Specifically, the guiding inclined surface is gradually increased along the radial dimension of the installation cavity 13 from the side close to the insertion port to the side away from the insertion port.

[0051] In addition, in order to improve the supporting and fixing effect of the flexible positioning part, especially when the flexible positioning part adopts multiple silicone protrusions 15, on the cigarette rod body 200, the projection of the end of the flexible positioning part used to abut the outer wall of the cigarette rod body 200 on the plane parallel to the radial direction of the installation cavity 13 presents an arc structure, that is, the end of the flexible positioning part is set in an arc shape. By setting the end of the flexible positioning part in an arc structure, the fit between the flexible positioning part and the outer wall of the cigarette rod body 200 is improved, thereby further improving the reliability of the flexible positioning part in supporting and fixing the cigarette rod body 200.

[0052] The embodiment of the present application also provides a cigarette rod assembly, including a cigarette rod body 200 and a cigarette rod bracket 100 provided in the above embodiment, and the cigarette rod body 200 is detachably mounted in the mounting cavity 13 of the cigarette rod bracket 100.

[0053] The charging port is located at one end of the bracket shell 10 away from the insertion port of the installation cavity 13. The charging port is connected to the battery through a circuit board, and the conductive pin is connected to the battery through a circuit board. The battery is used to supply power to the atomizer core of the cigarette rod body 200 through the conductive pin. After the cigarette rod body 200 is inserted into the installation cavity 13, the power connection pin is connected to the conductive pin to realize the electrical connection between the battery and the atomizer core.
