[0025] In the description of the present utility model, if there are descriptions of quantities, the meaning of several is one or more, the meaning of multiple is two or more, greater than, less than, exceeding, etc. are understood as not including the present number, and above, below, within, etc. are understood as including the present number. If there are descriptions of first and second, they are only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence relationship of the indicated technical features.

[0026] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0027] Such as Figures 1 to 8As shown in the figure, the utility model discloses an electronic cigarette with an external battery, which includes an electronic cigarette body 1 and an external battery compartment 2. The electronic cigarette body 1 includes a cartridge body 11 and a power supply component arranged at the lower end of the cartridge body 11. The power supply component includes an auxiliary battery 12 and a first circuit board component 13 electrically connected to the auxiliary battery 12. The cartridge body 11 includes an atomization core component electrically connected to the first circuit board component 13. The external battery compartment 2 includes a cartridge case 201 detachably connected to one side of the electronic cigarette body 1, a main battery 21 arranged in the cartridge case 201, and a second circuit board component 23 electrically connected to the main battery 21. An electrical connection mechanism for electrically connecting the second circuit board component 23 and the first circuit board component 13 and a circuit switch mechanism for controlling the on-off of the power supply circuit of the auxiliary battery 12 are arranged between the external battery compartment 2 and the electronic cigarette body 1.

[0028] When in use, the external battery compartment 2 can be connected to the electronic cigarette body 1. At this time, the circuit switch mechanism will control the power supply circuit board of the auxiliary battery 12 to disconnect, while the power supply circuit of the main battery 21 is connected to the first circuit board component 13 through the electrical connection mechanism, so as to realize the power supply of the main battery 21 to the atomization core component and ensure the normal use of the electronic cigarette. When the e-liquid of the disposable electronic cigarette is used up, the external battery compartment 2 can be removed and connected to a new electronic cigarette to continue to supply power to the new electronic cigarette. When the main battery 21 runs out of power, the external battery compartment 2 can be separated from the electronic cigarette body 1. When separated, the power supply circuit of the main battery 21 is disconnected from the first circuit board component. At the same time, the circuit board switch mechanism will control the power supply circuit of the auxiliary battery 12 to conduct, so that the normal use of the electronic cigarette will not be affected when the external battery compartment 2 is removed for charging. Of course, it can also be directly powered by the auxiliary battery 12.

[0029] The utility model is powered by setting a relatively large-capacity external battery, which can ensure the normal power consumption requirements of the electronic cigarette. Only a relatively small-capacity auxiliary battery 12 is arranged in the electronic cigarette body 1 to play an auxiliary role. This not only reduces the manufacturing cost of the disposable electronic cigarette, but also reduces the environmental pollution after the e-liquid of the electronic cigarette is used up and discarded.

[0030] In the present utility model, the electrical connection mechanism includes a connection contact 16 provided on an end face of the electronic cigarette body 1 close to one end of the external battery compartment 2, and a connection contact pin 25 provided on an end face of the external battery compartment 2 close to one end of the electronic cigarette body 1 and adapted to the connection contact 16. The connection contact pin 25 is an elastic contact pin. The connection contact 16 is electrically connected to the first circuit board assembly 13, and the connection contact pin 25 is electrically connected to the second circuit board assembly 23. When the external battery compartment 2 is connected to the electronic cigarette body 1, the circuit can be conducted through the connection contact 16 and the connection contact pin 25, ensuring that the power supply circuit of the main battery 21 is connected to the first circuit board assembly 13.

[0031] In the present utility model, the circuit switching mechanism includes a conducting elastic sheet 19, a movable contact pin 15 and a top column 24. The first circuit board assembly 13 includes a first PCBA board. The first PCBA board is provided with a first conducting contact and a second conducting contact. One end of the conducting elastic sheet 19 is fixedly connected to the first conducting contact, and a conducting contact piece 18 is fixedly provided on the second conducting contact. The other end of the conducting elastic sheet 19 is pressed on the conducting contact piece 18 to realize the conduction of the power supply circuit of the auxiliary battery 12. The movable contact pin 15 is provided at one end of the electronic cigarette body 1 close to the external battery compartment 2 and can elastically expand and contract. The top column 24 is provided at one end of the external battery compartment 2 close to the electronic cigarette body 1 and can push the movable contact pin 15 to move inward to separate the conducting elastic sheet 19 from the conducting contact piece 18, realizing the disconnection of the power supply circuit of the auxiliary battery 12. When the external battery compartment 2 is connected to the electronic cigarette body 1, the top column 24 on the external battery compartment 2 will push the movable contact pin 15 to move inward, and the movable contact pin 15 will separate the conducting elastic sheet 19 from the conducting contact piece 18, realizing the disconnection of the power supply circuit of the auxiliary battery 12. When the external battery compartment is completely connected to the electronic cigarette, at this time, the connection contact pin 25 on the external battery compartment 2 will contact the connection contact 16 on the electronic cigarette body 1 to realize the access of the power supply circuit of the main battery 21. Since the electronic cigarette can be used normally without connecting the main battery 21, there is a set of working circuits in the electronic cigarette body 1 and a set of working circuits in the external battery compartment 2. If the power supply circuits of the main battery 21 and the auxiliary battery 12 are not switched, it will cause conflicts between the two sets of working circuits, and the main battery 21 and the auxiliary battery 12 in the external battery compartment 2 will charge the auxiliary battery 12 when connected. When charging directly without passing through the protection circuit, it is very easy to cause the battery core to catch fire and cause safety accidents. By setting the circuit switching mechanism, it is possible to prevent the power supply circuit of the main battery 21 from being connected to the power supply circuit of the auxiliary battery 12, realizing the rapid switching of the power supply circuit. The control is simple and convenient, and the cost is low.

[0032] Such as Figure 7As shown, in the present utility model, the movable spring pin 15 includes a fixed sleeve, a needle rod inserted into the fixed sleeve, and a compression spring sleeved on the needle rod and disposed within the fixed sleeve to limit the telescopic movement of the needle rod. Both the conduction contact piece 18 and the conduction spring piece 19 are perpendicular to the needle rod. When the external battery compartment 2 is connected to the electronic cigarette body 1, the ejector pin 24 will push one end of the needle rod inward, and the other end of the needle rod can push one end of the conduction spring piece 19 to separate it from the conduction contact piece 18. Under normal circumstances, the conduction spring piece 19 is elastically pressed against the conduction contact piece 18. When the ejector pin 24 pushes the needle rod inward, the needle rod can abut against one end of the conduction spring piece 19 to separate the conduction spring piece 19 from the conduction contact piece 18, realizing the disconnection of the power supply circuit of the auxiliary battery 12; when the ejector pin 24 disengages from the needle rod, the needle rod separates from the conduction spring piece 19 under the action of the compression spring. At this time, the conduction spring piece 19 will resume contact with the conduction contact piece 18 under its own elastic force, thereby realizing the connection of the power supply circuit of the auxiliary battery 12. This structure is simple, easy to operate, low in cost, and stable and reliable in operation.

[0033] As Figure 8 shown, in some embodiments, the movable spring pin 15 includes a fixed sleeve, a needle rod inserted into the fixed sleeve, and a compression spring sleeved on the needle rod and disposed within the fixed sleeve to limit the telescopic movement of the needle rod. The conduction contact piece 18 is parallel to the needle rod. A pressing plate 151 is provided at one end of the needle rod away from the ejector pin 24 to press against the upper end of the conduction spring piece 19 so that the other end of the conduction spring piece 19 contacts the conduction contact piece 18. When the external battery compartment 2 is connected to the electronic cigarette body 1, the ejector pin 24 will push one end of the needle rod inward, and the pressing plate 151 at the other end of the needle rod separates from the conduction spring piece 19, causing the conduction spring piece 19 to separate from the conduction contact piece 18 under its own elastic force. Under normal circumstances, the pressing plate 151 is pressed against the upper end of the conduction spring piece 19, causing the conduction spring piece 19 and the conduction contact piece 18 to be pressed together. When the ejector pin 24 pushes the needle rod inward, the pressing plate 151 disengages from the conduction spring piece 19, and the conduction spring piece 19 will separate from the conduction contact piece 18 under its own elastic force, thereby realizing the disconnection of the power supply circuit of the auxiliary battery 12; when the ejector pin 24 disengages from the needle rod, the pressing plate 151 will reset and press against the conduction spring piece 19. At this time, the conduction spring piece 19 contacts the conduction contact piece 18, thereby realizing the connection of the power supply circuit of the auxiliary battery 12. This structure is simple, easy to operate, low in cost, and stable and reliable in operation.

[0034] In the present utility model, a circular docking protrusion is provided at one end of the electronic cigarette body 1 close to the external battery compartment 2. The circular docking protrusion is provided with a docking hole, and the fixed sleeve is fixedly installed in the docking hole. One end of the external battery compartment 2 close to the electronic cigarette body 1 is provided with a circular groove adapted to the circular docking protrusion, and the top column 24 is arranged at the center of the circular groove. This structure can play a role in guiding and limiting, ensuring the smooth docking of the external battery compartment 2 and the electronic cigarette body 1.

[0035] In the present utility model, the first circuit board assembly 13 further includes a first microphone component 14 electrically connected to the first PCBA board. The atomization core assembly includes an oil cup and a heating core arranged in the oil cup. The heating core includes two groups of heating sheets electrically connected to the first PCBA board. When powered by the auxiliary battery 12, since the working current of the auxiliary battery 12 is small, only a single group of heating sheets can be supported to work. When an external battery is connected, two groups of heating sheets can work simultaneously. This can meet different usage requirements.

[0036] In the present utility model, the second circuit board assembly 23 includes a second PCBA board and a second microphone component 29 electrically connected to the second PCBA board. One end of the external battery compartment 2 close to the electronic cigarette body 1 is further provided with a first communication hole 26 for cooperating with the second microphone component 29. One end of the electronic cigarette body 1 close to the external battery compartment 2 is further provided with a second communication hole 17 that can communicate with the first communication hole 26. When the main battery 21 is connected, the power supply circuit of the auxiliary battery 12 is in a disconnected state. At this time, the first microphone component 14 will not work. Therefore, by arranging the second microphone component 29 in the external battery compartment 2 and providing a communication hole communicating with the electronic cigarette body 1, the normal operation of the electronic cigarette is realized.

[0037] In the present utility model, a magnetic attraction mechanism 3 is provided between the electronic cigarette body 1 and the external battery compartment 2. It is convenient for the docking and fixing of the external battery compartment 2 and the electronic cigarette body 1, and is also convenient for disassembly and assembly.

[0038] In the present utility model, a display screen 27 and a charging interface 28 are provided at one end of the external battery compartment 2 away from the electronic cigarette body 1. The display screen 27 is electrically connected to the second PCBA board for displaying the power of the main battery 21, and the charging interface 28 is used to charge the main battery 21. The external battery compartment 2 can be recycled, saving the usage cost.

[0039] In the present utility model, a mouthpiece is further provided at the upper end of the cartridge body 11. The electronic cigarette body 1 includes an upper shell 101 and a lower shell 102. The cartridge body 11 is disposed within the upper shell 101, and the power supply assembly is disposed within the lower shell 102. A shock-absorbing foam 22 is further provided between the main battery 21 and the side wall of the cartridge case 201, which serves to protect the main battery 21.

[0040] In the present utility model, a lift switch is further provided at the lower end of the electronic cigarette body 1 for controlling the air intake amount to achieve different inhalation effects.

[0041] In the present utility model, a large-capacity and rechargeable external battery is provided for power supply, and it can supply power to multiple disposable electronic cigarettes. Only a small-capacity auxiliary battery 12 is provided in each electronic cigarette body 1 for auxiliary use. This not only reduces the manufacturing cost of the disposable electronic cigarette, but also reduces environmental pollution after the e-liquid in the electronic cigarette is exhausted and discarded.

[0042] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can be made, which should all be regarded as belonging to the protection scope of the present utility model.
