It is understood that the lower shell 12 and the upper shell 11 can be detachably connected through a snap structure, a magnetic attraction structure, or the like. The upper shell 11 and the lower shell 12 may be formed by injection molding. The suction port 13 may be provided at the upper case 11, the lower case 12, or a connection position of both, flexibly adjusted according to a design structure of a product.

It is also understood that the power supply 3 may be provided on the lower case 12 or the upper case 11 as long as the power supply of the power supply 3 can be turned on to a predetermined portion on the inverter device 2; further, the power source 3 may be a lithium battery, which has the advantages of small volume and high energy density, and of course, the power source 3 may also be other types of batteries, and is not limited to the lithium battery.

As shown in fig. 1, 2 and 3, in some embodiments, the housing 1 is provided with a rotation avoiding opening 121, and a portion of the conversion device 2 is exposed in the rotation avoiding opening 121.

It can be understood that the user can operate the switching device 2 to rotate by rotating the position avoiding opening 121, so that the switching device 2 rotates to a preset position according to a preset direction, and the on-off of the cartridge 4 is controlled. The opening size and the opening position of the rotary position avoiding opening 121 can be flexibly adjusted according to the actual structure of a product, preferably, the rotary position avoiding opening 121 can be arranged at a position where a user can easily stir and adjust when holding the product, and the use convenience of the product is improved.

As shown in fig. 3, the conversion device 2 in some embodiments includes a receiving assembly 21 and a rotating assembly 22. The containing assembly 21 is arranged in the shell 1, and the containing assembly 21 is used for containing the cartridges 4 and further transmitting the current to the predetermined cartridges 4, so that the corresponding cartridges 4 heat and atomize the tobacco tar. The rotating assembly 22 is arranged in the shell 1, the rotating assembly 22 is electrically connected with the power supply 3, the rotating assembly 22 can rotate relative to the containing assembly 21, when the containing assembly 21 rotates to a preset position, the current of the power supply 3 can be connected to the containing assembly 21, and then the corresponding smoke cartridge 4 works to heat and atomize the tobacco tar.

It can be understood that when the rotating assembly 22 rotates to different predetermined positions, different portions of the power supply 3 and the receiving assembly 21 are electrically connected, that is, when the relative angle between the rotating assembly 22 and the receiving assembly 21 changes, the connection position of the power supply 3 with the receiving assembly 21 through the rotating assembly 22 also changes, and along with the change of the connection position, the cartridge 4 of the receiving assembly 21 connected with the power supply 3 also changes, so as to achieve the purpose of switching different operations of connecting the cartridge 4 with the power supply 3.

As shown in fig. 3, 4, 5, 6 and 7, the receiving assembly 21 is provided with at least two cartridge receiving locations 2121 and at least two conductive units 211. Each cartridge storage position 2121 is for storing a cartridge 4. Each conductive unit 211 corresponds to the cartridge 4 in the cartridge receiving position 2121 and is electrically connected to the same, and each conductive unit 211 is used for being connected to the current supplied by the other parts and transmitting the current to the corresponding cartridge 4, so that the corresponding cartridge 4 heats and atomizes the tobacco tar. The rotating assembly 22 is provided with a conducting unit 221, and the conducting unit 221 is electrically connected with the power supply 3. When the rotating assembly 22 rotates, the conducting unit 221 is switched to be electrically connected with at least one of the conducting units 211, so as to switch on at least one cartridge 4 in the cartridge accommodating position 2121 with the power supply 3 for atomizing the tobacco tar.

It will be appreciated that a single cartridge 4 may be housed in a single cartridge receiving bay 2121, although it is possible to house two or more cartridges 4 in a single cartridge receiving bay 2121. The conductive unit 211 may be a double-ended pogo pin, a single-ended pogo pin, or a conductive pogo pin without elastic expansion function, and of course, the conductive unit 211 may also be other structures capable of connecting and transmitting current.

Further, in some embodiments, the number of the conductive units 211 and the number of the cartridges 4 may be equal or different, and for this, each conductive unit 211 and each cartridge receiving position 2121 may have at least the following different corresponding connection modes:

first, each of the cartridges 4 and each of the conductive units 211 may be electrically connected in a one-to-one correspondence manner, so that each of the conductive units 211 only supplies power to one of the cartridges 4 corresponding thereto when being electrically connected to the conductive unit 221, that is, each of the conductive units 211 only correspondingly transmits current to one of the cartridges 4; thus, when the conduction unit 221 connected with the power supply 3 is switched to be in conductive connection with different conductive units 211, the power supply 3 is also switched to be in conductive connection with the smoke cartridge 4 corresponding to the switched conductive unit 211, so as to achieve the purpose of switching different smoke cartridges 4 to work; thus, if the conducting units 221 are conducted simultaneously to connect the conducting units 211, the atomized tobacco tar with mixed flavors can be produced;

secondly, the partial conductive units 211 and the partial cartridges 4 can be electrically connected in a one-to-one correspondence manner, so that when the partial conductive units 211 are separately electrically connected with the conductive unit 221, only a single cartridge 4 is electrically connected with the power supply 3 correspondingly; secondly, in another part of the conductive unit 211, the conductive unit 211 can be electrically connected with two or more cartridges 4 correspondingly, that is, when the conductive unit 211 in this part is separately electrically connected with the conductive unit 221, the two or more cartridges 4 are electrically connected with the power supply 3, so that the product can produce atomized tobacco tar with mixed taste; in this way, the user can switch or mix the flavors of the tobacco tar by adjusting the rotating component 22;

thirdly, each conductive unit 211 is connected with two or more smoke cartridges 4, so that when the rotating assembly 22 is rotated each time to switch the conductive unit 221 to be connected with a different conductive unit 211, the product supplies power to the smoke cartridge 4 corresponding to the switched conductive unit 211, thereby realizing the switching of the combined work of different smoke cartridges 4 and achieving the purpose of switching the taste of the tobacco tar;

in addition, the conductive unit 211 and the cartridge 4 may be modified in other connection manners according to different product designs, and are not limited to the connection manners described above.

Further, the conductive unit 211 may include a positive wiring member electrically connected to the positive electrode of the cartridge 4 and a negative wiring member electrically connected to the negative electrode of the cartridge 4 in some embodiments. When the rotating assembly 22 rotates to a predetermined position, the conducting unit 221 is electrically connected with the positive wiring piece and the negative wiring piece in the corresponding conducting unit 211, so that the positive and negative electrodes of the cartridge 4 are conducted with the positive and negative electrodes of the power supply 3;

the conductive unit 211 may in other embodiments comprise a positive connection piece connected to the positive pole of the cartridges 4, while the negative pole of each cartridge 4 may be connected in parallel and then directly to the negative pole of the power source 3. When the rotating assembly 22 rotates to a predetermined position, the conducting unit 221 is electrically connected with the positive connecting piece of the corresponding conducting unit 211, so that the positive electrode of the corresponding cartridge 4 can be switched to be conducted with the positive electrode of the power supply 3, the operation of the corresponding cartridge 4 is realized, and the switching of the taste is realized. In addition, the negative electrode of the smoke cartridge 4 and the negative electrode of the power supply 4 have high electrical safety.

As shown in fig. 3, 4 and 7, the receiving assembly 21 further includes a base 212, each cartridge receiving location 2121 and each conductive unit 211 are respectively disposed on the base 212, and the base 212 functions to fix the cartridges 4 and the conductive units 211, and fix the relative positions between each cartridge 4 and each conductive unit 211. One end of each conductive unit 211 is electrically connected to the cartridge 4, and the other end of each conductive unit 211 is used for abutting against the conductive unit 221.

It is understood that a single cartridge receiving location 2121 may receive only one cartridge 4, and may also receive two or more cartridges; grooves or holes correspondingly matched with the cartridges 4 can be formed in the cartridge accommodating positions 2121; secondly, a corresponding structure for fixing the cartridges 4 can be arranged on each cartridge accommodating position 2121; of course, the cartridge 4 may be directly mounted on the cartridge receiving portion 2121 of the base 212 by bonding or fastening.

Specifically, as shown in fig. 8, the base 212 may be provided with three cartridge receiving locations 2121 in some embodiments, each cartridge receiving location 2121 is provided with one cartridge 4, and meanwhile, three conductive units 211 may be further provided on the base 212, and each conductive unit 211 is electrically connected to each cartridge 4 in a one-to-one correspondence manner; the conducting unit 221 includes two first conducting portions 2211a, and the two first conducting portions 2211a are switched to be electrically connected with two of the three conducting units 211 when the rotating assembly 22 rotates, so as to connect two of the three cartridges 4 with the power supply 3.

It can be understood that the three conductive units 211 are circumferentially distributed around the central axis of the base 212, and the distance between two adjacent conductive units 211 is equal, that is, the angle a1 between two adjacent conductive units 211 and the center of the base 212 is 120 °; the center of the two first conductive portions 2211a forms an angle a2 with the center of the rotating assembly 22 of 120 °. As such, in the rotation process, there are three kinds of cooperation conditions between the two first conductive portions 2211a and the three conductive units 211, and two different cartridges 4 can be powered in each kind of cooperation condition, so that the product can produce atomized tobacco tar of three kinds of mixed flavors.

Specifically, as shown in fig. 9, in other embodiments, the seat body 212 may be provided with three cartridge receiving locations 2121, each cartridge receiving location 2121 is provided with one cartridge 4, and meanwhile, the seat body 212 may be provided with three conductive units 211, and each conductive unit 211 is electrically connected to each cartridge 4 in a one-to-one correspondence manner; the conducting unit 221 includes three second conducting portions 2211b, and the three second conducting portions 2211b are switched to be in conducting connection with one or two of the three conducting units 211 when the rotating wheel 222 rotates, so that one or two of the three cartridges 4 are connected with the power supply 3.

It can be understood that the three conductive units 211 are circumferentially distributed around the central axis of the base 212, and the distance between two adjacent conductive units 211 is equal, that is, the angle B1 between two adjacent conductive units 211 and the center of the base 212 is 120 °; an angle B2 from the center of each of the two adjacent second conductive portions 2211B to the center of the runner 222 is 60 °, so that an angle B3 ═ B2 ═ 2 ═ 120 ° from the centers of the second conductive portions 2211B on both sides to the center of the runner 222. Thus, during rotation of the wheel 222, several conditions may occur:

first, in fig. 9, when the middle second conductive part 2211b of the three second conductive parts 2211b is in contact with one of the conductive units 211, the other two second conductive parts 2211b located at both sides are not in contact with any one of the conductive units 211; that is, the current of the power source 3 is transmitted to only one cartridge 4; thus, any one of the three cartridges 4 can work independently to atomize the tobacco tar;

secondly, in fig. 9, when two second conducting portions 2211b at two side positions of the three second conducting portions 2211b are respectively contacted with the two conducting units 211, the current of the power supply 3 is transmitted to the two cartridges 4 through the two second conducting portions 2211b and the two conducting units 211, so that the two cartridges 4 work simultaneously to generate mixed atomized tobacco tar; combining the two situations, the product of this example is able to produce three single flavor atomized tobacco products as well as three mixed flavor atomized tobacco products.

In addition to the above, in other embodiments of the present invention, different numbers and different positions of the conductive units 211 may be disposed on the seat 212, and different numbers and different positions of the conductive units 221 may be disposed on the rotating wheel 222, and the conductive units 211 and the conductive units 221 may be electrically connected in a predetermined manner to control the operation of the corresponding cartridges 4, and are not limited to the corresponding relationship between angles.

As shown in fig. 4, the base 212 may be provided with a plurality of isolation grooves 2122 in some embodiments, each isolation groove 2122 corresponds to each cartridge receiving position 2121, and an end of each conductive unit 211 is correspondingly exposed in each isolation groove 2122.

It is understood that each isolation groove 2122 serves to prevent the conductive elements 211 in two adjacent isolation grooves from being shorted with each other, and further, parts for electrically connecting with each conductive element 211 are always limited in the corresponding isolation groove 2122.

As shown in fig. 3 to 7, the receiving assembly 21 further includes a cover 213, a circuit board 215, and at least two cover conductive members 214 in some embodiments. Each capping conductor 214 is disposed on the capping 213, and each capping conductor 214 is configured to be electrically connected to the circuit board 215. A plurality of contact sites 2151 are disposed on circuit board 215, each contact site 2151 configured to be electrically connected to conductive element 221.

One end of each of the capping conductive members 214 is in contact with each of the conductive units 211 in a one-to-one correspondence, the other end of each of the capping conductive members 214 is electrically connected to the circuit board 215, and the conductive unit 221 is switched to be electrically connected to at least one of the contact sites 2151 when the rotating assembly 22 rotates, so that the power source 3 is electrically connected to the corresponding capping conductive member 214 through the circuit board 215.

As can be understood from fig. 5, the press cover 213 may be provided with a positioning groove 2131 adapted to the contour of the circuit board 215, and the circuit board 215 is always limited in the positioning groove 2131, so as to avoid the situation that the press cover conductive member 214 cannot be electrically connected to the predetermined position of the circuit board 215 due to the misalignment between the circuit board 215 and the press cover 213, thereby improving the operational reliability of the product.

It can be understood that the position of each capping conductive member 214 on the capping 213 corresponds to the position of each conductive unit 211 on the base 212, when the capping 213 is correspondingly matched with the base 212, each capping conductive member 214 is separately and correspondingly connected with each conductive unit 211, and current can be transmitted between the capping conductive member 214 and the conductive unit 211; secondly, when a single electric contact on the circuit board 215 is powered, the current may only power a single capping conductive member 214 through the series circuit on the circuit board 215, and the current may also power two or more capping conductive members 214 through the parallel circuit on the circuit board 215, which may be flexibly adjusted according to different actual products.

In order to better understand the technical solution of the present invention, the working process and the working principle of the electronic atomizer 1 of the present invention are as follows:

under the condition that the cigarette cartridge 4 works at present, when a user rotates the rotating assembly 22, the rotating assembly 22 drives the conducting unit 221 to rotate synchronously, and the rotated conducting unit 221 is separated from the current contact position 2151 on the circuit board 215, so that the current of the power supply 3 cannot be transmitted to the current contact position 2151, and the current flowing to the cigarette cartridge 4 in the current work is cut off;

as the rotating component 22 drives the conducting unit 221 to further rotate, when the conducting unit 221 rotates to contact with other contact positions 2151 on the circuit board 215, the current of the power supply 3 is transmitted to the contact positions 2151 through the conducting unit 221, the circuit on the circuit board 215 transmits the current to the conductive cover member 214 and the conductive unit 211 corresponding to the contact positions 2151, and the current of the power supply 3 is switched to the corresponding smoke bomb 4, so as to achieve the purpose of switching the taste of the smoke bomb 4.

As shown in fig. 5, the capping conductor 214 may be a double-ended pogo pin or a single-ended pogo pin in some embodiments. It is understood that other configurations known in the art for current transmission may be used for the capping conductive member 214; both ends of the double-ended elastic pin are elastic, so that both ends of the gland conductive member 214 can be tightly supported with the circuit board 215 and the conductive unit 211 respectively, and thus, on one hand, the gland conductive member 214 can be prevented from being in virtual connection with the circuit board 215 and the conductive unit 211 to cause current open circuit, on the other hand, the circuit board 215 can be supported towards the direction far away from the gland 213, so that the circuit board 215 and the conductive unit 221 can be tightly supported, and the current on the conductive unit 221 can be transmitted to the contact position 2151 on the circuit board 215.

As shown in fig. 3 to 7, the rotating assembly 22 may include a rotating wheel 222 in some embodiments, the conducting unit 221 is disposed on the rotating wheel 222, and the rotating wheel 222 drives the conducting unit 221 to rotate, so that the conducting unit 221 abuts against at least one conducting unit 211.

It can be understood that the rotating wheel 222 can be rotatably disposed in the housing 1 through a rotating shaft and a bearing; secondly, the rotation axis of the rotating wheel 222 can be flexibly arranged at each position in the housing 1, preferably, the rotation axis of the rotating wheel 222 is arranged to be parallel to the central axis of the housing 1, so that the rotating wheel 222 can be exposed in the rotation avoiding opening 121 on the side wall of the housing 1, a user can operate the rotating wheel 222 while holding the housing 1, and the use convenience of the product is improved. The runner 222 may be configured in a cylindrical or pie shape; the wheel 222 may be provided on the surface of the wheel 222 to increase the friction between the user's hand and the wheel 222, thereby preventing the wheel 222 from slipping when the user operates the wheel to rotate.

Further, the conducting unit 221 may be a conducting elastic sheet in some embodiments, and the conducting elastic sheet can be tightly attached to the circuit board 215 under the action of its own elastic force, so that the conducting elastic sheet can tightly abut against the contact position 2151 on the circuit board 215 when rotating to a predetermined position, and it is ensured that the current of the power supply 3 can be transmitted to the circuit board 215 through the conducting elastic sheet; of course, the conduction unit 221 may be a conductive structure such as a spring-biased conductive sheet, and particularly, a structure capable of stably transmitting current is preferable.

Further, the conducting unit 221 may be provided with an arc-shaped contact surface in some embodiments, and the arc-shaped contact surface is entirely in close contact with the circuit board 215 during the rotation of the rotating wheel 222, so that the arc-shaped contact surface can be in conductive communication with only one contact position 2151 on the circuit board 215 when the rotating wheel 222 is rotated, and the arc-shaped contact surface can also be in conductive communication with two or more contact positions 2151 on the circuit board 215 simultaneously along with the rotation of the rotating wheel 222.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention.
