It should be understood that these azimuth terms are merely for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Thus, these azimuth terms should not be understood as a limitation to the embodiments of the present application.
An embodiment of the present application provides an aerosol generating device configured to generating aerosol for user inhalation. With reference to FIGS. 1 to 3, the aerosol generating device comprises a shell 10, an atomizer 20, and a battery 30.
A mounting cavity 10a is provided inside the shell 10.
An aerosol generating substrate is provided in the atomizer 20 for generating aerosol for user inhalation.
At least a portion of the atomizer 20 is arranged within the mounting cavity 10a. In this way, on the one hand, the shell 10 can protect the atomizer 20 to a certain extent, on the other hand, a position of the atomizer with respect to the shell can be restricted by a cooperation between an inner wall of the mounting cavity 10a and a portion of the atomizer 20 located in the mounting cavity 10a. The atomizer 20 is provided with an air intake passage 20a and an atomizing cavity 25a.
The aerosol formed by the atomizer 20 is formed in the atomizing cavity 25a. The ambient air enters into the atomizing cavity 25a through the air intake passage 20a. The aerosol is carried by a flow of the air which is then discharged from the aerosol generating device, for user inhalation.
The battery 30 is configured to supply power to the atomizer 20 which can convert the aerosol generating substrate inside the atomizer into aerosol.
It should be noted that the specific principle of supplying power to the atomizer 20 by the battery 30 to generate aerosol has been applied in the related art, and will not be described herein.
The battery 30 is arranged in the mounting cavity 10a so that the shell 10 can protect the battery 30 and reduce a probability of short circuit or similar issues caused by a collision of the battery 30 with a foreign object outside the aerosol generating device during using of the battery.
The battery 30 is detachably connected to the atomizer 20, which means that a connection between physical structures of the battery 30 and the atomizer 20 can be removed so that the battery and the atomizer can be separated from each other if necessary.
An electrical conduction between the battery 30 and the atomizer 20 means that battery can be electrically connected to the atomizer to enable the battery 30 to supply power to the atomizer 20.
It can be understood that in a state that the battery 30 and the atomizer 20 are separated from each other, the electrical conduction between the battery 30 and the atomizer 20 may be or may not be cut off.
The shell 10 comprises a plurality of sub-shells 11. Edges of at least part of the sub-shells 11 are detachably connected to each other so as to define a mounting cavity 10a together.
In this way, by disconnecting the edges of the sub-shells 11 which are detachably connected to each other, an opening can be formed on the shell 10.
In a disconnection state of the sub-shells 11 which are detachable, the mounting cavity 10a is open to an outside of the aerosol generating device so as to allow the atomizer 20 and the battery 30 to be removed from the mounting cavity 10a. That is, the atomizer 20 and the battery 30 can be removed from the mounting cavity 10a through the opening formed by the edges of the detachable sub-shells 11.
After the atomizer 20 and the battery 30 are removed from the mounting cavity 10a, the atomizer 20 and the battery 30 can be disassembled and separated from each other. That is, in this state, the aerosol generating device can be divided into at least three parts: the shell 10, the atomizer 20 and the battery 30. The edges of the sub-shells 11 are detachably connected, so that the operator can observe detachably connected portions of each sub-shell 11 from the outside of the shell 10, and the operator can apply a force to the detachably connected portions of the sub-shells 11 from the outside of the shell 10 so as to realize the disconnection.
It can be understood that during inhaling of aerosol by the user, negative pressure is formed in the air intake passage 20a and the atomizing cavity 25a, so that the air outside enters into the air intake passage 20a through an inlet of the air intake passage 20a under the influence of pressure.
It can be understood that the air outside can pass through the shell and enter into the mounting cavity 10a due to a permeability of the material of the sub-shell itself and seams presented between the respective detachable sub-shells.
Both the air intake passage 20a and the atomizing cavity 25a are hermetically insulated from the mounting cavity 10a, such that the air cannot enter into the air intake passage 20a and the atomizing cavity 25a from the mounting cavity 10a directly.
In the aerosol generating device in the embodiments of the present application, by providing the sub-shells 11 which are detachable, the atomizer 20 and the battery 30 can be taken out from the mounting cavity 10a by disassembling the sub-shells in a case of using issues of the aerosol generating device or an exhaustion of the aerosol generating substrate. Then, according to actual needs, the atomizer 20 and the battery 30 can be disassembled from each other to recycle or replace the battery 30 and to facilitate a maintenance of the atomizer 20, such that various parts and related materials in the aerosol generating device can be recycled. At the same time, during the inhaling of aerosol by the user, an adverse influence on an amplitude of pressure drop in the air intake passage 20a caused by the entering of the air into the air intake passage 20a from the mounting cavity 10a directly is reduced, which is beneficial to improving an user experience.
The detachable connection between the sub-shells 11 may be a connection manner which enables disassembling and assembling for a plurality of times, or a connection manner which only allows disconnecting for one time after assembling.
In some embodiments, with reference to FIG. 1, there are two sub-shells 11 which are fitted to each other to form the mounting cavity 10a.
In some embodiments, material of the shell 10 is degradable material, so that after the shell 10 is disassembled, an adverse impact on the environment can be reduced by means of natural degradation even in a case of discarding directly.
The specific type of material of the shell 10 is not limited. For example, the specific type of material of the shell is photodegradable plastic, biodegradable plastic, water degradable plastic, paper and so on.
In some embodiments, the shell 10 is made of paper, so that the user can separate the detachably connected portions of the sub-shells 11 from each other by directly tearing, thereby facilitating the removal of the atomizer 20 and the battery 30 from the mounting cavity 10a.
In the embodiment in which the shell 10 is made of paper, there is no limitation to the manner in which the edges of the sub-shells 11 are detachably connected.
For example, the edges of the sub-shells are bonded to each other in order to reduce a manufacturing difficulty and to improve connection strength between the sub-shells.
The specific manner in which the user disassembles the sub-shells 11 is not limited.
In some embodiments, with reference to FIGS. 1 to 3, a seam 10b is formed at a joint of two adjacent sub-shells 11. A pulling handle 12 is provided on at least one side of the seam 10b perpendicular to an extending direction of the seam. The pulling handle 12 protrudes from an outer surface of the shell 10 and extends perpendicular to the extending direction of the seam 10b.
In this way, it is convenient for the user to separate two sub-shells 11 connected to each other at a position adjacent to the seam 10b of the pulling handle 12 by applying a pulling force to the pulling handle 12, thereby reducing an operation difficulty for the user.
The pulling handle 12 may be made of a same material with the shell 10, or may be made of a different material.
In an embodiment in which the material of the sub-shells 11 is paper, contacting surfaces of two adjacent sub-shells 11 forming the seam 10b are bonded to each other so as to secure a position of each sub-shell 11.
A width of the contacting surface may be 1 mm to 10 mm. A specific width value of the contacting surface is not limited. For example, the specific width value of the contacting surface is 1 mm, 2 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm and so on.
In some embodiments, the atomizer 20 is provided with a mounting groove. One side of the mounting groove opens so that the battery 30 can be inserted into the mounting groove through an opening portion of the mounting groove.
A mounting position is provided for the battery 30 by means of the mounting groove, so that the battery 30 can be removed from the mounting cavity 10a along with the atomizer 20. At the same time, a position of the battery 30 is restricted by an inner wall of the mounting groove, which reduces a probability that the detachable connection between the battery 30 and the atomizer 20 is disconnected or the electrical conduction is interrupted due to a relative movement between the battery 30 and the atomizer 20, so as to improve a stability of power supply of the battery 30.
In some embodiments, an inner wall of the mounting groove perpendicular to an insertion direction of the battery 30 abuts against an outer surface of the battery 30 so as to realize a detachable connection between the battery and the mounting groove by means of a friction between them.
The specific manner in which the electrical conduction between the atomizer 20 and the battery 30 is achieved is not limited.
As an example, with reference to FIGS. 3 to 8, the aerosol generating device comprises an electric wire 40, an electric pin 50 and an electric connector 60. One of the electric pin 50 and the electric connector 60 is electrically connected to one end of the electric wire 40. One of the battery 30 and the atomizer 20 is electrically connected to another end of the electric wire 40. Another one of the electric pin 50 and the electric connector 60 is electrically connected to another one of the battery 30 and the atomizer 20. The electric pin 50 is configured to be inserted into the electric connector 60 so as to be electrically connected to the electric connector.
The electric connector 60 is provided with a conductive through-hole, an inner wall of which is provided with a conductive elastic member. The conductive elastic member can be elastically deformed in a direction perpendicular to an extending direction of the conductive through-hole. The electric pin 50 is inserted through the conductive through-hole and abuts against the conductive elastic member to compress the conductive elastic member, so that the electric pin 50 is in a fitting state with the conductive elastic member and the inner wall of the conductive through-hole respectively, to prevent the electric pin 50 from exiting the conductive through-hole by means of friction. By applying a force to the electric pin 50 or the electric connector 60 in a direction away from each other and greater than a friction between the electric pin 50 and the electric connector 60, the electric pin 50 can be pulled out of the conductive through-hole to separate the electric pin 50 from the electric connector 60. Thus, a detachable connection between the electric connector 60 and the electric pin 50 is achieved.
The conductive elastic member can be electrically connected to the battery 30 directly, or the electrical conduction between the conductive elastic member and the battery can be achieved by means of the electric wire 40 electrically connecting the battery to the conductive elastic member.
In this way, the indirect detachable connection and electrical conduction between the battery 30 and the atomizer 20 are realized by the electric pin 50 and the electric connector 60. At the same time, since the electric wire 40 is a flexible structure, it is convenient to realize a flexible arrangement of the battery 30 with respect to atomizer 20 by bending the electric wire 40, which is beneficial to improve a space utilization efficiency of the mounting cavity 10a and makes a structure of the aerosol generating device more compact.
It should be noted that the specific structure of the electric pin 50 and the electric connector 60 and the specific manner for realizing the electrical conduction between the electric pin and the electric connector 60 have been applied in the related art, and will not be described herein.
The specific type of the electric connector 60 is not limited. For example, the electric connector is a four-hole wire connector or the like.
In some embodiments, with reference to FIGS. 4 and 5, there are two electric wires 40 so as to be matched to a positive electrode and a negative electrode of the battery 30 respectively.
In some embodiments, there are two electric pins 50 so as to be matched to the positive electrode and the negative electrode of the battery 30 respectively.
The specific structure of the atomizer 20 is not limited.
As an example, with reference to FIGS. 3 to 8, the atomizer 20 comprises a pneumatic switch 21, an atomizing core 22, and an atomizing base 25. The atomizing cavity 25a, a pneumatic passage 25b and a first air intake sub-passage 25c are provided in the atomizing base. The atomizing core 22 is located within the atomizing cavity 25a. The pneumatic passage 25b communicates the mounting cavity 10a with the first air intake sub-passage 25c. The first air inlet sub-passage 25c communicates an outside of the shell 10 with the atomizing cavity 25a. The pneumatic switch 21 is arranged in the pneumatic passage 25b. The first air intake sub-passage 25c is at least a portion of the air intake passage 20a.
The aerosol generating substrate is stored in the atomizing core 22, and the atomizing core 22 can be electrically connected to the battery 30. In a state that the battery 30 supplies power to the atomizing core 22, the aerosol generating substrate in the atomizing core 22 forms aerosol for user inhalation.
The first air intake sub-passage 25c is in communication with the atomizing cavity 25a so that a pressure in the first air intake sub-passage is substantially the same with that of the atomizing cavity.
One end of the pneumatic passage 25b is in communication with the first air intake sub-passage 25c, so that a sensing area of the pneumatic switch 21 facing the one end of the pneumatic passage 25b can sense the pressure in the first air intake sub-passage 25c. Another end of the pneumatic passage 25b is in communication with the mounting cavity 10a, so that a sensing area of the pneumatic switch 21 facing said another end of the pneumatic passage 25b can sense a pressure in the mounting cavity 10a.
A pressure difference is formed between the first air intake sub-passage 25c and the mounting cavity 10a during the inhalation of aerosol by the user. The pneumatic switch 21 can control the power supplying of the battery 30 to the atomizing core 22 to generate aerosol by sensing the pressure difference.
It can be understood that only when a magnitude of the pressure difference reaches a preset amplitude, the pneumatic switch 21 can control the atomizer 20 to generate aerosol.
It can be understood that during the inhalation of aerosol by the user, the air outside the shell 10 can pass through the shell 10 and enter into the mounting cavity 10a, which is unbeneficial for the magnitude of the pressure difference between the first air intake sub-passage 25c and the mounting cavity 10a to reach a requirement that enable the pneumatic switch 21 to control the atomizer 20 to generate aerosol.
In some embodiments in which the pneumatic switch 21, atomizing core 22 and atomizing base 25 are provided, with reference to FIGS. 3 to 5, the atomizer 20 comprises an isolation shield 23 and an electrode column 24. The isolation shield 23 is hermetically mounted around the atomizing base 25 to define an isolation cavity 23a. One end of the electrode column 24 passes through the atomizing base 25 and is electrically connected to the atomizing core 22. Another end of the electrode column is located within the isolation cavity 23a. Each of the first air intake sub-passage 25c and the pneumatic passage 25b communicates the isolation cavity 23a with the atomizing cavity 25a. One end of the electric pin 50 hermetically passes through the isolation shield 23, extends into the isolation cavity 23a and is electrically connected to the electrode column 24. The isolation shield 23 is provided with an airflow passage 23b communicating the isolation cavity 23a with the outside of the shell 10. The first air intake sub-passage 25c, the airflow passage 23b and the isolation cavity 23a form the air intake passage 20a. The electric connector 60 is detachably connected to the isolation shield 23 and electrically connected to the electric wire 40.
The isolation cavity 23a and the mounting cavity 10a form spaces independent from each other in airtightness by means of a hermetical fitting between the isolation shield 23 and the atomizing base 25. Since the air would not flow between the mounting cavity 10a and the isolation cavity 23a, the air in the mounting cavity is unable to change the pressure in the isolation cavity 23a. Therefore, even if the air outside passes through the shell 10 and enters into the mounting cavity 10a when inhalation of the user, the pressure in the isolation cavity 23a can hardly be affected.
Moreover, the electric pin 50 is hermetically fitted to and fixed to the isolation shield 23, so that it is difficult for the air in the mounting cavity 10a to enter into the isolation cavity 23a through a seam 10b between the electric pin 50 and the isolation shield.
The battery 30 is electrically connected to the atomizing core 22 through a conductive path formed by the electric wire 40, the electric connector 60, the electric pin 50, and the electrode column 24 successively.
In this way, controlling the power supplying by the battery 30 to the atomizing core 22 is achieved by means of sensing the pressure difference between the isolation cavity 23a and the atomizing cavity 25 by the pneumatic switch 21. An adverse effect on a normal operation of the pneumatic switch 21 caused by an negative impact of the air tightness within the mounting cavity 10a due to an air permeability of paper material is reduced, which improves an user experience.
It can be appreciated that a detachable connection between the electric connector 60 and an outer surface of the isolation shield 23 is achieved for ease of disassembly and assembly operations.
The specific manner in which the electric connector 60 and the isolation shield 23 are detachably connected is not limited.
As an example, one of the electric connector 60 and the isolation shield 23 is provided with a slot, and the other of the electric connector and the isolation shield is provided with an elastic clasp, which is able to be inserted into or removed from the slot by means of an elastic deformation of the elastic clasp, so as to realize the detachable connection between the electric connector 60 and the isolation shield 23.
The specific manner in which a sealing between the isolation shield 23 and the atomizing base 25 is not limited. For example, a sealing ring is provided in a seam 10b between the isolation shield 23 and the atomizing base 25.
It can be understood that after the user completes inhaling the aerosol, the aerosol remaining within the atomizing cavity 25a can condense to form a condensate, which may cause corrosion and softening of the shell 10 if the condensate comes into contact with the shell 10 made by paper, leading to an adverse impact for the user to grip the shell 10 and an adverse impact on the use by the user.
Therefore, by providing the isolation shield 23, the condensate can flow into the isolation cavity 23a and be stored therein, thereby reducing a probability for the condensate to flow out and come into contact with the shell 10 made by paper, so as to protect the shell 10.
In some embodiments, with reference to FIGS. 3 and 4, the shell 10 is provided with an air intake hole 10c communicating the outside of the shell 10 with the mounting cavity 10a. The outer surface of the isolation shield 23 is provided with an air intake protrusion 231 extending into the air intake hole 10c. An inlet of the airflow passage 23b is provided at an end surface of the air intake protrusion 231 perpendicular to an extending direction of the air intake hole 10c.
In this way, on the one hand, it is beneficial for the isolation cavity 23a to be in direct communication with the outside of the shell 10, which further reduces the adverse influence of the air in the mounting cavity 10a on the change of the pressure in the isolation cavity 23a. On the other hand, it is beneficial for the condensate formed by the aerosol in the isolation cavity 23a to directly flow out of the shell 10, which reduces the probability that the condensate in the isolation cavity 23a flows into the mounting cavity 10a, comes into contact with the shell 10 for a long time and causes an adverse effect on the shell 10, so as to improve a service life of the aerosol generating device.
In some embodiments, with reference to FIG. 3, the air intake protrusion 231 is located at an end of the isolation shield 23 along a longitudinal direction of the aerosol generating device.
The longitudinal direction of the aerosol generating device refers to a rectilinear direction in which a largest dimension among three-dimensional dimensions of the aerosol generating device is oriented.
In this way, it is beneficial to reduce a probability that the user blocks the inlet of the airflow passage 23b while holding and using the aerosol generating device.
It will be appreciated that a mounting position of the electric pin 50 facilitates an assembling/a disassembling of the electric pin on/from the electric connector 60.
As an example, with reference to FIGS. 3 to 5, the electric pin 50 and the battery 30 are arranged on two opposite sides of the isolation shield 23 respectively.
In this way, it is beneficial to reduce an interference of the battery 30 and the atomizing base 25 in the process of assembling or disassembling the electric connector 60, so as to improve the convenience of operation.
In some embodiments, with reference to FIG. 4, a first wire slot 23c is provided on a side of the isolation shield 23 away from the atomizing base 25. A side of the first wire slot 23c which faces away from the atomizing base 23 opens and is through along a direction from the electric pin 50 towards the battery 30. The electric wire 40 is embedded in the first wire slot 23c.
An inner wall of the first wire slot 23c can constrain a position of the electric wire 40, thereby reducing a probability of fraction between the electric wire and the inner wall of the mounting cavity 10a and other components in the mounting cavity 10a due to a movement of the electric wire 40 during a movement of the aerosol generating device. Therefore, a risk of poor electrical conductivity caused by a broken of the electric wire 40 due to friction is reduced. At the same time, the electric wire 40 is arranged in the first wire slot 23c, which is beneficial to improving a compactness and uniformity for the assembly of the electric wire 40.
It will be appreciated that the battery 30 supplies power to the pneumatic switch 21 to make the pneumatic switch operate.
The specific manner in which the battery 30 supplies power to the pneumatic switch 21 is not limited.
As an example, with reference to FIG. 5, the atomizer 20 comprises a first patch cord provided in the isolation cavity 23a and connecting the pneumatic switch 21 to the electric pin 50 so as to realize an electrically connection between the pneumatic switch and the electric pin.
In this way, the power supplying by the battery 30 to the pneumatic switch 21 is achieved by the first patch cord 26. At the same time, a flexibly bendable characteristic of the first patch cord 26 enables a more flexible arrangement for a position of the pneumatic switch 21 with respect to the electric pin 50, and also enables a more compact structure of the atomizer 20.
In some embodiments, an extending direction of the electrode column 24 is the same as an extending direction of the electric pin 50. A projection of the electrode column on a projection plane perpendicular to the extending direction of the electrode column and the electric pin at least partially overlaps with a projection of the electric pin on the projection plane. In this way, a size of the atomizer 20 in the extending direction of the electrode column 24 can be reduced, such that the structure of the atomizer 20 is more compact.
In some embodiments, the extending direction of the electrode column 24 and the electric pin 50 is the length direction of the aerosol generating device.
The specific manner in which the electrical connection between the electrode column 24 and the electric pin 50 is achieved is not limited.
As an example, with reference to FIG. 5, the atomizer 20 comprises a second patch cord 27 provided in the isolation cavity 23a and connecting the electrode column 24 to the electric pin 50 so as to realize an electrically connection between the electrode column and the electric pin.
In this way, the power supplying by the battery 30 to the atomizing core 22 is achieved by the second patch cord 27. At the same time, a flexibly bendable characteristic of the second patch cord 27 enables a more flexible arrangement for a position of the electrode column 24 with respect to the electric pin 50, and also enables a more compact structure of the atomizer 20.
In some embodiments, with reference to FIG. 5, a fixing base 251 is provided on an inner wall of the isolation cavity 23a. The fixing base 251 is provided with a second wire slot which extends through the fixing base and opens on one side of the second wire slot perpendicular to an extending direction of the second wire slot. At least one of the first patch cord 26 and the second patch cord 27 is embedded into the second wire slot through an opening portion the second wire slot.
An inner wall of the second wire slot positions and constraints the first patch cord 26 and second patch cord 27, thereby reducing a probability of fraction between the first patch cord/the second patch cord and the inner wall of the isolation cavity 23a and other components in the isolation cavity 23a due to a movement of the first patch cord 26/the second patch cord 27 during the movement of the aerosol generating device. Therefore, a risk of poor electrical conductivity caused by a broken of the first patch cord/the second patch cord due to friction is reduced.
It will be appreciated that a portion of the isolation shield 23 and a portion of the atomizing base 25 together form the inner wall of the isolation cavity 23a.
It can be understood that one end of the first patch cord 26 and one end of the second patch cord 27 are electrically connected to the electric pin 50 by soldering.
In some embodiments, the material of the shell 10 is a degradable plastic such that the air outside the shell 10 cannot directly pass through the shell 10 and enter into the mounting cavity 10a.
In some embodiments, with reference to FIGS. 6 to 8, the atomizer 20 comprises the pneumatic switch 21, the atomizing core 22 and the atomizing base 25. The atomizing cavity 25a, the pneumatic passage 25b and a second air intake sub-passage 25d are provided in the atomizing base 25. The atomizing core 22 is located within the atomizing cavity 25a. The electric pin 50 passes through the atomizing base 25 and is electrically connected to the atomizing core 22. The second air intake sub-passage communicates the atomizing cavity 25a with the outside of the shell 10. The pneumatic passage 25b communicates the mounting cavity 10a with the second air intake sub-passage 25d which forms the air intake passage 20a. The pneumatic switch 21 is arranged in the pneumatic passage 25b.
That is, the electric pin 50 functions as the conductive column as mentioned in the previous embodiments, and the electric pin 50 is able to directly supply power to the atomizer 20.
In this way, the structure of the atomizer 20 is simplified and the number of components is reduced.
In some embodiments, with reference to FIGS. 7 and 8, a portion of the atomizing base 25 extends in a curved manner to define an avoidance groove 25e, in which at least a portion of the electric connector 60 is located.
In this way, the second air intake sub-passage 25d is able to avoid the electric pin 50 along an extending direction of the second air intake sub-passage, so as to avoid an interference between the second air intake sub-passage and the electric pin. Furthermore, an inner wall of the avoidance groove can constrain and position the electric connector 60, so as to reduce a probability that the electric pin 50 is disengaged from the electric connector 60 due to vibration as so on.
