The invention relates to the technical field of atomization, in particular to a battery pack and an electronic atomization device.

Background

The electronic atomization device atomizes the atomization substrate through the atomization assembly to generate aerosol for a user to suck so as to achieve the purpose of obtaining substances in the aerosol. The battery pack is used for supplying power to the atomization assembly so as to control the atomization assembly to atomize or stop atomizing.

Among the prior art, battery pack and atomization component dock each other through the butt joint face laminating, and the electrode setting is on the butt joint face to realize battery pack and atomization component's electricity and be connected, make battery pack can provide the electric energy for atomization component. However, the battery assembly and the atomization assembly are butted with each other in a way of jointing the butting surfaces, and when the connection between the battery assembly and the atomization assembly is not tight enough or under the action of external force, the electrode contact between the battery assembly and the atomization assembly is easy to fail, so that the phenomenon that the atomization assembly cannot be normally supplied with power due to poor contact occurs.

Disclosure of Invention

Therefore, it is necessary to provide a battery assembly and an electronic atomization device that overcome the above-mentioned drawbacks, in order to solve the problem in the prior art that the battery assembly and the atomization assembly are butted with each other by fitting the butting surfaces, and when the connection between the battery assembly and the atomization assembly is not tight enough or under the action of external force, the electrode contact between the battery assembly and the atomization assembly is easy to fail.

A battery assembly comprises a battery bracket and an inserting part, wherein the battery bracket is provided with a first matching surface which is detachably matched and connected with an atomizing assembly, and the inserting part is convexly arranged on the first matching surface and is provided with a first electrode;

In one embodiment, the inserting portion has a first mating surface intersecting with the first mating surface, and the first electrode is disposed on the first mating surface.

In one embodiment, the first mating face is perpendicular to the first mating face. Thus, because the first electrode and the second electrode of the atomizing assembly have a certain electric contact area, when the battery assembly and the atomizing assembly are loosened (i.e. slightly displaced relative to each other) in a direction perpendicular to the first mating surface, the first electrode and the second electrode of the atomizing assembly can be ensured to be in electric contact, and the stability of power supply is improved.

In one embodiment, the battery assembly further comprises an airflow sensor mounted on the battery bracket, the insertion portion is provided with an airflow channel, one end of the airflow channel is used for being in gas communication with the atomization assembly, and the other end of the airflow channel is in gas communication with the airflow sensor.

In this way, when a user sucks on the atomizing assembly, the gas in the gas flow channel enters the atomizing assembly, so that negative pressure is formed. Because the airflow channel is in gas communication with the airflow sensor, the airflow sensor can detect that airflow passes through the airflow channel, and therefore the battery assembly is controlled to supply power to the atomization assembly through the first electrode. The atomization assembly atomizes the atomization substrate under the action of the electric energy provided by the battery assembly, and aerosol formed by atomization flows out along with the airflow and is inhaled by a user.

When the user stops pumping on the atomizing assembly, the gas in the gas flow channel stops entering the atomizing assembly, so that the negative pressure disappears. At this moment, the airflow sensor detects that no airflow passes through the airflow channel, so that the battery assembly is controlled to stop supplying power to the atomization assembly, and the atomization assembly stops atomizing the atomized matrix.

In one embodiment, the insertion portion includes a body protruding from the first mating surface and having a receiving cavity and an opening communicating with the receiving cavity, and a mounting block disposed in the receiving cavity and having a side facing the opening for mounting the first electrode;

wherein a gap between an inner wall of the accommodating cavity and an outer wall of the mounting block is configured to form the airflow channel.

In one embodiment, the first mating surface is provided with a magnetic attraction piece, and the magnetic attraction piece is used for being attracted and fixed with the atomization component.

In one embodiment, the first mating surface is provided with at least two magnetic attracting elements, and the at least two magnetic attracting elements are arranged at intervals along the length direction of the first mating surface.

In one embodiment, the insertion portion is located at one end of the first mating surface in the length direction.

An electronic atomizer comprises an atomizer assembly and a battery assembly as described in any of the above embodiments.

In one embodiment, the atomizing assembly has a second mating surface and a plug cavity, the second mating surface is used for detachably mating with the first mating surface, the second mating surface is provided with a plug opening communicated with the plug cavity, and a second electrode is arranged in the plug cavity;

when the second mating surface is mated with the first mating surface, the inserting portion is inserted into the inserting cavity through the inserting opening, and the first electrode is electrically contacted with the second electrode.

The battery assembly and the electronic atomization device are detachably connected by utilizing the first matching surface of the battery bracket to be matched and connected with the atomization assembly. When the first mating surface is mated with the atomizing assembly, the inserting portion protruding on the first mating surface is inserted into the atomizing assembly, so that the first electrode on the inserting portion is electrically connected with the atomizing assembly. The inserting portion is inserted into the atomizing assembly in an inserting mode, so that the inserting portion is limited on the plane where the first matching and connecting surface is located, the reliability of electric connection between the first electrode on the inserting portion and the atomizing assembly is improved, and the phenomenon that the first electrode cannot normally supply power to the atomizing assembly due to poor contact is avoided.

Referring to fig. 1 and 2, an embodiment of the present invention provides an electronic atomizer, which includes a battery assembly 10 and an atomizer assembly 20 coupled to the battery assembly 10. The battery assembly 10 is electrically connected to the atomizing assembly 20 for supplying power to the atomizing assembly 20. The atomizing assembly 20 atomizes the aerosol substrate using the electrical energy provided by the battery assembly 10 and generates an aerosol for consumption by the user.

In the embodiment of the present invention, the battery pack 10 includes a battery holder 11 and an insertion portion 12. The battery holder 11 has a first mating surface 110 for detachably mating with the atomizing assembly 20. The inserting portion 12 is protruded on the first mating surface 110, and is mounted with a first electrode 121. When the atomizing assembly 20 is coupled to the first coupling surface 110, the inserting portion 12 is inserted into the atomizing assembly 20, and the first electrode 121 is electrically connected to the atomizing assembly 20, so that the electric energy of the battery assembly 10 is transmitted to the atomizing assembly 20 through the first electrode 121, and the atomizing assembly 20 is powered.

Thus, the battery assembly 10 is detachably connected to the atomizing assembly 20 by the first mating surface 110 of the battery holder 11 mating with the atomizing assembly 20. When the first mating surface 110 is mated with the atomizing assembly 20, the inserting portion 12 convexly disposed on the first mating surface 110 is inserted into the atomizing assembly 20, so that the first electrode 121 on the inserting portion 12 is electrically connected with the atomizing assembly 20. Because the inserting portion 12 is inserted into the atomizing assembly 20, the inserting portion 12 is limited on the plane where the first mating surface 110 is located, which is beneficial to improving the reliability of the electrical connection between the first electrode 121 on the inserting portion 12 and the atomizing assembly 20, and the phenomenon that the first electrode 121 cannot normally supply power to the atomizing assembly 20 due to poor contact is avoided.

It should be noted that, by installing the first electrode 121 on the inserting portion 12 and inserting the inserting portion 12 into the atomizing assembly 20, the length of the first electrode 121 can be shortened properly under the condition of satisfying the electrical connection condition, compared with the prior art that the electrode is installed on the mating surface, so as to achieve the effect of saving space and cost.

In some embodiments, the inserting portion 12 has a first mating surface 124 intersecting the first mating surface 110, and the first electrode 121 is disposed on the first mating surface 124. When the atomizing element 20 is coupled to the first coupling surface 110, the first coupling surface 124 is coupled to a second coupling surface 23 of the atomizing element 20, such that the first electrode 121 is electrically connected to the atomizing element 20. In this way, the first mating surface 124 is positioned to be in contact with the second mating surface 23 of the atomizing assembly 20, which will be described below, so that the first electrode 121 and the atomizing assembly 20 can be electrically connected to each other when the inserting portion 12 is inserted into the atomizing assembly 20.

Preferably, the first mating surface 110 and the first mating surface 124 are perpendicular to each other. In this way, since the first electrode 121 and the second electrode 24 of the atomizing assembly 20 described below have a certain electrical contact area, when the battery assembly 10 and the atomizing assembly 20 are loosened (i.e., slightly displaced relative to each other) in a direction perpendicular to the first mating surface 110, the first electrode 121 and the second electrode 24 of the atomizing assembly 20 can be ensured to be in electrical contact, and the stability of power supply is improved.

In one embodiment, the first mating surface 124 defines a first electrode hole (not shown) in which the first electrode 121 is disposed. Further, the first electrode 121 includes a first positive electrode and a first negative electrode, the first electrode hole includes a first positive electrode hole and a first negative electrode hole, the first positive electrode is installed in the first positive electrode hole, and the first negative electrode is installed in the first negative electrode hole.

In some embodiments, the battery assembly 10 also includes an airflow sensor 13 mounted on the battery bracket 11. The insertion portion 12 is opened with an air flow passage having one end for air communication with the atomizing assembly 20 and the other end in air communication with the air flow sensor 13. Alternatively, the airflow sensor 13 may be a microphone.

In this manner, when a user draws on the atomizing assembly 20, the air in the air flow channel enters the atomizing assembly 20, thereby creating a negative pressure. Since the airflow channel is in gas communication with the airflow sensor 13, the airflow sensor 13 can detect that airflow passes through the airflow channel, so as to control the battery assembly 10 to supply power to the atomizing assembly 20 through the first electrode 121. The atomizing assembly 20 atomizes the aerosol substrate under the power supplied by the battery assembly 10, and the aerosol formed by the atomization flows out along with the airflow to be inhaled by the user.

When the user stops drawing on the atomizing assembly 20, the air in the air flow path stops entering the atomizing assembly 20, and the negative pressure disappears. At this time, the airflow sensor 13 detects that no airflow passes through the airflow channel, so as to control the battery assembly 10 to stop supplying power to the atomizing assembly 20, so that the atomizing assembly 20 stops atomizing the atomized substrate.

It should be noted that the air flow channel is formed on the inserting portion 12, so that the end of the air flow channel, which is communicated with the atomizing assembly 20, is higher than the first mating surface 110, so that the condensate or the leakage liquid cannot enter the air flow sensor 13 from the air flow channel, and the condensate or the leakage liquid is prevented from corroding and damaging the air flow sensor 13 by the condensate or the leakage liquid.

Referring to fig. 3, in the embodiment, the inserting portion 12 includes a body 122 and a mounting block 123. The body 122 is protruded on the first mating surface 110 of the battery holder 11, and has a receiving cavity 1221 and an opening (not shown) communicating with the receiving cavity 1221. The mounting block 123 is disposed in the accommodating chamber 1221, and the first electrode 121 is mounted on a side facing the opening. The gap between the inner wall of the accommodating cavity 1221 and the outer wall of the mounting block 123 forms the airflow channel. Alternatively, the body 122 and the battery holder 11 may be integrally formed.

It should be noted that, in the embodiment shown in fig. 3, the outer wall of the mounting block 123 is provided with an air flow groove 1231 recessed inwards. When the mounting block 123 is assembled into the accommodating cavity 1221, the inner wall of the accommodating cavity 1221 and the airflow groove 1231 enclose to form the airflow channel.

Of course, in another embodiment, the airflow groove 1231 may be opened on the inner wall of the accommodating chamber 1221. When the mounting block 123 is assembled into the accommodating cavity 1221, the outer wall of the mounting block 123 and the airflow groove 1231 enclose to form the airflow channel. In another embodiment, airflow grooves 1231 may be formed on both the outer wall of the mounting block 123 and the inner wall of the accommodating cavity 1221. After the mounting block 123 is assembled into the accommodating cavity 1221, the airflow channel 1231 on the outer wall of the mounting block 123 and the airflow channel 1231 on the inner wall of the accommodating cavity 1221 jointly enclose to form the airflow channel.

It should also be noted that the gas flow passage of the insert portion 12 can be in gas communication with the atomizing assembly 20 in various ways, and is not limited herein. For example, in one embodiment, the gas flow passages extend directly through the mounting block 123 to the side facing the opening such that the gas flow passages are in gas communication with the atomizing assembly 20. In another embodiment, the gas flow channel extends through the first electrode hole, and the inner wall of the first electrode hole is provided with a vent groove, so that the gas flow channel is in gas communication with the atomizing assembly 20 through the vent groove.

In the embodiment, the battery holder 11 has a mounting groove 112 and a communication passage 113 for communicating the mounting groove 112 with the airflow passage, and the mounting groove 112 is used for accommodating the airflow sensor 13. As such, the communication passage 113 communicates the air flow passage with the mounting groove 112 so that the air flow sensor 13 can detect the air flow in the air flow passage.

In particular embodiments, the battery assembly 10 further includes a battery 14, and the battery 14 is mounted on the battery holder 11 and electrically connected to the airflow sensor 13. Thus, when the airflow sensor 13 detects that airflow is flowing through the airflow channel (i.e., when the user draws on the airflow channel), the airflow sensor 13 controls the battery 14 to supply power to the atomizing assembly 20 through the first electrode 121, so that the atomizing assembly 20 atomizes the atomized substrate by using the electric energy. When the airflow sensor 13 detects that there is no airflow in the airflow channel (when the user stops drawing), the airflow sensor 13 controls the battery 14 to stop supplying power to the atomizing assembly 20, so that the atomizing assembly 20 stops atomizing the atomized substrate.

Referring to fig. 1 and 2, in some embodiments, the first mating surface 110 is provided with a magnetic member 111, and the magnetic member 111 is used for being attracted and fixed to the atomizing assembly 20. Thus, the magnetic member 111 on the first mating surface 110 is fixed to the atomizing assembly 20, so as to connect the battery assembly 10 and the atomizing assembly 20.

Further, the first mating surface 110 is provided with at least two magnetic attracting elements 111, and the at least two magnetic attracting elements 111 are arranged at intervals along the length direction of the first mating surface 110. Therefore, the at least two magnetic attraction pieces 111 are simultaneously and fixedly attracted to the atomization assembly 20, which is beneficial to improving the bonding strength between the battery assembly 10 and the atomization assembly 20.

Further, the inserting portion 12 is located at one end of the first mating surface 110 in the length direction, on one hand, the influence on the arrangement of the magnetic attraction pieces 111 is favorably reduced, and on the other hand, the inserting portion 12 is offset, so that the inserting portion 12 is inserted into the side of the atomizing assembly 20 (i.e., the inserting cavity 22 is offset), which is favorable for reducing the influence on the arrangement of the atomizing cores of the atomizing assembly 20.

Referring to fig. 1, in the embodiment of the present invention, the atomizing assembly 20 has a second mating surface 21 and a plug cavity 22, and the second mating surface 21 is detachably mated with the first mating surface 110. The second mating surface 21 has a plug opening (not shown) communicating with the plug cavity 22. A second electrode 24 is disposed within the plug cavity 22. When the second mating surface 21 is mated with the first mating surface 110, the inserting portion 12 is inserted into the inserting cavity 22 through the inserting opening, and the first electrode 121 is electrically connected with the second electrode 24.

In one embodiment, the second mating surface 21 is provided with a magnetic coupling member 25 capable of generating a magnetic coupling effect with the magnetic coupling member 111, so that the battery assembly 10 and the atomizing assembly 20 are fixed to the magnetic coupling member 25 by the magnetic coupling member 111. It is understood that the magnetic engaging members 25 are disposed in a one-to-one correspondence with the magnetic elements 111, i.e., the number of magnetic engaging members 25 is equal to the number of magnetic elements.

Alternatively, the magnetic element 111 may be a magnet, and the magnetic mating element 25 may be a magnet or a substance (e.g., an iron block) capable of being attracted by a magnet. Of course, in other embodiments, the magnetic member 111 may not be a magnet, but a substance (e.g. an iron block) capable of being attracted by a magnet, and the magnetic engaging member 25 is a magnet.

In one embodiment, the atomizing assembly 20 has a second mating surface 23 as a portion of the inner wall of the plug chamber 22, and the second electrode 24 is disposed on the second mating surface 23. When the inserting portion 12 is inserted into the inserting cavity 22, the second mating surface 23 is configured to be attached to the first mating surface 124, so that the second electrode 24 on the second mating surface 23 is electrically connected to the second electrode 24 on the first mating surface 124.

The battery pack and the electronic atomization device have at least the following advantages: the battery assembly 10 is detachably connected to the atomizing assembly 20 by the first mating surface 110 of the battery holder 11 mating with the atomizing assembly 20. When the first mating surface 110 is mated with the atomizing assembly 20, the inserting portion 12 convexly disposed on the first mating surface 110 is inserted into the atomizing assembly 20, so that the first electrode 121 on the inserting portion 12 is electrically connected with the atomizing assembly 20. Because the inserting portion 12 is inserted into the atomizing assembly 20, the inserting portion 12 is limited on the plane where the first mating surface 110 is located, which is beneficial to improving the reliability of the electrical connection between the first electrode 121 on the inserting portion 12 and the atomizing assembly 20, and the phenomenon that the first electrode 121 cannot normally supply power to the atomizing assembly 20 due to poor contact is avoided;

the first electrode 121 is installed on the inserting portion 12, and the inserting portion 12 is inserted into the atomizing assembly 20, so that compared with the prior art in which the electrode is installed on the mating surface, the length of the first electrode 121 can be appropriately shortened under the condition of satisfying the electrical connection condition, thereby achieving the effect of saving space and cost;

since the first mating surface 110 and the first mating surface 124 are perpendicular to each other, and the first electrode 121 and the second electrode 24 of the atomizing assembly 20 have a certain electrical contact area, when the battery assembly 10 and the atomizing assembly 20 are loosened (i.e., slightly displaced relative to each other) in a direction perpendicular to the first mating surface 110, the first electrode 121 and the second electrode 24 of the atomizing assembly 20 can be ensured to be in electrical contact, and the stability of power supply is improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
