Description

Technical Field

[0001] The present application relates to the field of atomization technology, and more specifically, to an aerosol generating device. Background Art

[0002] An aerosol generating device is a small device that can heat an aerosol generating substrate and generate an aerosol by means of heat not burning (HNB). The shell of the aerosol generating device is provided with a cavity and a perforation, and the aerosol generating substrate can extend into the cavity through the perforation. In the related art, the aerosol generating device is provided with a shielding member that can block or open the perforation. After the aerosol generating substrate is taken out of the cavity, the shielding member can block the perforation to prevent foreign matter from entering the cavity. Among them, since residues may remain in the cavity when the aerosol generating substrate is taken out of the cavity, the user needs to clean the inside of the cavity to prevent the residues from affecting the installation of the aerosol generating substrate. However, the setting of the shielding member will affect the user's cleaning operation. For example, the user needs to apply force to the shielding member to open the perforation, which will cause a heavy burden on the user's operation and a low cleaning efficiency.

[0040] See also Figure 1 and Figure 2 The aerosol generating device 100 of the embodiment of the present application includes a body 10, a cover 20 and a detection assembly 30. The body 10 is provided with a heating chamber 11, and the heating chamber 11 is used to accommodate the aerosol generating matrix 200. The cover 20 is provided with a through hole 21 connected to the heating chamber 11, and the cover 20 can switch between a first state and a second state relative to the body 10. The detection assembly 30 includes a moving part 31 and a detection member 33. The moving part 31 is arranged on the cover 20, and can move relative to the cover 20 to be in a state of blocking the through hole 21 or a state of opening the through hole 21. The moving part 31 includes a detected member 315. When the cover 20 is in the first state, the cover 20 is connected to the body 10, and the detection member 33 detects the state of the moving part 31 relative to the through hole 21; when the cover 20 is in the second state, the detected member 315 exceeds the detection range of the detection member 33. It should be noted that, in some embodiments, the detection member 33 can detect the moving component 31 to confirm whether the aerosol generating substrate 200 is accommodated in the heating chamber 11 .

[0041] In some embodiments, the body 10 includes a housing 15, and the aerosol generating device 100 may further include a power supply unit 50 and a heating assembly 60. The power supply unit 50 is electrically connected to the detection member 33 and the heating assembly 60, and is used to supply power to the detection member 33 and the heating assembly 60. The heating assembly 60 is electrically connected to the detection member 33, and when the detection member 33 confirms that the aerosol generating matrix 200 is accommodated in the heating chamber 11, the heating assembly 60 heats the aerosol generating matrix 200. It should be noted that in some embodiments, the heating assembly 60 is a structure that can generate heat energy or transfer heat energy to other parts. In some embodiments, the heating assembly 60 can directly convert other forms of energy such as electrical energy, chemical energy, solar energy, etc. into heat energy, and conduct it to other parts that need to be heated through heat transfer. In other embodiments, the heating assembly 60 can directly act on other forms of energy such as electromagnetic waves, lasers, infrared light or thermal radiation on the surface of the part to be heated, so as to increase the temperature of the area receiving the electromagnetic waves, lasers, infrared light or thermal radiation.

[0042] Specifically, please combine Figure 3 In some embodiments, the power supply unit 50 and the heating assembly 60 are both disposed in the housing 15, so that the housing 15 can protect the power supply unit 50 and the heating assembly 60. Figure 2 As shown in FIG. 1 ), the detection member 33 can output a heating signal. In this case, the power supply unit 50 can supply power to the heating component 60, so that the heating component 60 can heat and atomize the aerosol generating substrate 200 according to the heating signal; when the detection member 33 detects the moving part 31 (the detection member 315) to confirm that the aerosol generating substrate 200 is not accommodated in the heating chamber 11 (as shown in FIG. 1 ), the detection member 33 can output a heating signal. In this case, the power supply unit 50 can supply power to the heating component 60, so that the heating component 60 can heat and atomize the aerosol generating substrate 200 according to the heating signal; Figure 3 As shown), the detection member 33 is capable of outputting a shutdown signal or stopping outputting a heating signal. In this case, the power supply unit 50 will not supply power to the heating component 60, and the heating component 60 will stop heating the aerosol generating matrix 200.

[0043] In some embodiments, the entire moving part 31 may be the detected part 315, thereby improving the accuracy and sensitivity of the detection part 33 in detecting the detected part 315, thereby ensuring the stability and reliability of the operation of the aerosol generating device 100. For example, in the case where the detected part 315 is a magnetic element, the entire moving part 31 is a magnetic element that can provide a stronger magnetic field, thereby improving the accuracy and sensitivity of the detection of the detection part 33. In other embodiments, a part of the moving part 31 is the detected part 315, thereby, the setting position of the detected part 315 can be adaptively adjusted according to the installation position of the detection part 33, thereby improving the stability and reliability of the operation of the detection component 30.

[0044] It is understandable that in other embodiments, the detection member 33 can output other judgment signals. For example, when the detection member 33 detects the moving part 31 to confirm that the aerosol generating substrate 200 is accommodated in the heating chamber 11, the detection member 33 outputs not a heating signal, but a signal that triggers the aerosol generating device 100 to switch from sleep to standby. The embodiments of the present application are only described by taking the output of the heating signal of the detection member 33 when the detection member 33 detects the moving part 31 to confirm that the aerosol generating substrate 200 is accommodated in the heating chamber 11 as an example.

[0045] In some embodiments, the body 10 is provided with an opening 13 communicating with the heating chamber 11, and the aerosol generating substrate 200 passes through the opening 13 and is accommodated in the heating chamber 11. When the cover 20 is in the first state, the opening 13 corresponds to the through hole 21, and the moving part 31 can block the communication between the through hole 21 and the opening 13; when the cover 20 is in the second state, the cover 20 opens the opening 13.

[0046] Furthermore, in some embodiments, the main body 10 may also include a bracket 17 installed in the shell 15, the bracket 17 is provided with a heating chamber 11 and an opening 13 connected to the heating chamber 11, and the cover body 20 is provided with a through hole 21 connected to the heating chamber 11, that is, the heating chamber 11 can be connected to the outside through the through hole 21, thereby, the aerosol generating matrix 200 can pass through the through hole 21 and the opening 13 in turn and extend into the heating chamber 11.

[0047] Specifically, when the aerosol generating substrate 200 extends into the heating chamber 11 through the through hole 21 and the opening 13, the aerosol generating substrate 200 can push the moving part 31 to move relative to the cover 20 (including moving and rotating) so that the moving part 31 is in a state of opening the through hole 21, so that the aerosol generating substrate 200 can sequentially pass through the through hole 21 and the opening 13 and extend into the heating chamber 11. In this case, the detection member 33 can detect the detected member 315 to confirm that the aerosol generating substrate 200 is accommodated in the heating chamber 11, thereby allowing the heating component 60 to heat the aerosol generating substrate. 200 to generate aerosol for the user to inhale; when the user stops using the aerosol generating device 100, the aerosol generating matrix 200 can be pulled out so that the user can store the aerosol generating device 100. In this case, the moving part 31 can move relative to the cover body 20 to be in a state of blocking the perforation 21, and the detection part 33 can detect the detected part 315 to confirm that the aerosol generating matrix 200 is not accommodated in the heating chamber 11, thereby causing the heating component 60 to stop heating the aerosol generating matrix 200, thereby preventing the heating component 60 from being in a heating state all the time and causing damage. In addition, the setting of the moving part 31 can also prevent impurities such as water or dust from entering the body 10 through the perforation 21, causing damage to the components in the body 10, and prevent impurities such as water or dust from entering the heating chamber 11 through the perforation 21, causing the aerosol generating matrix 200 to be unable to be installed, thereby ensuring the normal operation of the aerosol generating device 100.

[0048] Among them, the aerosol generating substrate 200 is an element capable of generating aerosols. Specifically, the aerosol generating substrate 200 can be made into fine particles by heating or ultrasonic vibration, and mixed with air to form an aerosol. The form of the aerosol generating substrate 200 can be solid or liquid, wherein the aerosol generating substrate 200 can be sheet-shaped or columnar, etc. In the present application, the aerosol generating substrate 200 is cylindrical. Aerosols can be visible or invisible and can include steam (for example, fine particulate matter in a gaseous state, which is usually liquid or solid at room temperature) and liquid droplets of gas and condensed steam. The "aerosol" herein covers the aerosol generated when the aerosol generating substrate 200 in the heated aerosol generating device 100 is heated.

[0049] In some embodiments, the first state (eg Figure 2 or Figure 3 The first state (as shown in the figure) can be: the state of the cover 20 when the cover 20 is connected to the body 10, the through hole 21 corresponds to the opening 13, and the moving part 31 can block the communication between the through hole 21 and the opening 13; the second state (as shown in the figure) can be: the state of the cover 20 when the cover 20 is connected to the body 10, the through hole 21 corresponds to the opening 13, and the Figure 5 , Figure 6 or Figure 7) may be: the state of the cover 20 when the cover 20 is at least partially disconnected from the body 10 and the cover 20 opens the opening 13. It is understandable that in some embodiments, the switch of the cover 20 between the first state and the second state requires manual intervention, that is, the cover 20 is manually switched between the first state and the second state; or the cover 20 is manually switched between the first state and the second state with the help of a tool.

[0050] Specifically, in some embodiments, when the cover 20 is in the first state, if the moving part 31 moves relative to the cover 20 to be in a state of opening the perforation 21, the moving part 31 can enter the detection range of the detection member 33; if the moving part 31 moves relative to the cover 20 to be in a state of blocking the perforation 21, the detected part 315 exceeds the detection range of the detection member 33, thereby, when the cover 20 is in the first state, the detection member 33 can detect the moving part 31 to confirm whether the aerosol generating substrate 200 is accommodated in the heating chamber 11. When the cover 20 is in the second state, no matter whether the moving part 31 is in a state of blocking the perforation 21 or in a state of opening the perforation 21, the detected part 315 exceeds the detection range of the detection member 33, thereby, when the cover 20 is in the second state, the detection member 33 cannot detect the moving part 31 to confirm whether the aerosol generating substrate 200 is accommodated in the heating chamber 11. It is understandable that, in some embodiments, when the cover body 20 is in the second state, the cover body 20 opens the opening 13 , thereby allowing a user to clean the heating chamber 11 .

[0051] In the aerosol generating device 100 of the embodiment of the present application, the cover body 20 can switch between a first state and a second state. When the cover body 20 is in the second state, the detected component 315 is beyond the detection range of the detection component 33. Therefore, the moving component 31 does not affect the user's cleaning operation, thereby facilitating the user to clean the heating chamber 11, reducing the user's operating burden and improving the cleaning efficiency.

[0052] In addition, since there may be residues left in the heating chamber 11 when the aerosol generating substrate 200 is taken out from the heating chamber 11, in order to prevent the residues from affecting the installation and heating of the aerosol generating substrate 200, the user needs to clean the inside of the heating chamber 11. Generally, the user can use a tool (such as a cotton swab, etc.) to reach into the heating chamber 11 to clean the heating chamber 11. However, in the process of the tool reaching into the heating chamber 11, the moving part 31 can rotate relative to the cover body 20 to be in a state of opening the perforation 21. At this time, the moving part 31 is located within the detection range of the detection member 33, and thus, the heating assembly 60 will not be started to heat up as expected by the user, thereby affecting the user's normal cleaning. In the embodiment of the present application, when the cover body 20 is in the second state, the cover body 20 opens the opening 13, and the detected member 315 is beyond the detection range of the detection member 33. Therefore, when the user cleans the heating chamber 11, the detection member 33 will not cooperate with the moving part 31 to output a heating signal, that is, the heating component 60 will not be mistakenly started, thereby ensuring that the user can clean the heating chamber 11 normally.

[0053] The aerosol generating device 100 is further described below with reference to the accompanying drawings.

[0054] See also Figures 2 to 4 In some embodiments, the moving part 31 can rotate relative to the cover body 20 to switch between a state of blocking the perforation 21 and a state of opening the perforation 21. In other embodiments, the moving part 31 can move relative to the cover body 20 to switch between a state of blocking the perforation 21 and a state of opening the perforation 21. It should be noted that in the embodiments of the present application, only the example of the moving part 31 being able to rotate relative to the cover body 20 to switch between a state of blocking the perforation 21 and a state of opening the perforation 21 is used for explanation.

[0055] See also Figures 2 to 4 In some embodiments, the moving part 31 includes a rotating shaft 311, a shielding member 313, a detected member 315 and an elastic member 317. The rotating shaft 311 is rotatably mounted on the cover body 20. The shielding member 313 is connected to the rotating shaft 311 and can rotate with the rotating shaft 311. The detected member 315 is arranged on the shielding member 313 and can rotate with the shielding member 313. The detected member 315 is used to cooperate with the detecting member 33. The elastic member 317 is connected to the rotating shaft 311 and the shielding member 313 and is used to provide an elastic force. When the shielding member 313 rotates along the first direction X, the shielding member 313 is in a state of opening the perforation 21. The elastic force is used to rotate the shielding member 313 along the second direction Y so that the shielding member 313 is in a state of blocking the perforation 21. The second direction Y is opposite to the first direction X. It should be noted that in some embodiments, the elastic member 317 includes but is not limited to a compression spring or a tension spring.

[0056] Specifically, in some embodiments, the moving part 31 may be arranged on the side of the cover 20 facing the main body 10, whereby, in the process of the aerosol generating matrix 200 extending into the heating chamber 11 through the perforation 21, the force exerted by the aerosol generating matrix 200 on the shielding member 313 is greater than the elastic force exerted by the elastic member 317 on the shielding member 313, thereby enabling the shielding member 313 to rotate toward the direction of the main body 10 (i.e., rotate along the first direction X) to be in a state of opening the perforation 21; in the process of the aerosol generating matrix 200 being pulled out of the heating chamber 11, the force exerted by the aerosol generating matrix 200 on the shielding member 313 gradually disappears, thereby enabling the shielding member 313 to rotate in a direction away from the main body 10 (i.e., rotate along the second direction Y) under the action of the elastic force of the elastic member 317 to be in a state of shielding the perforation 21. It should be noted that the cross-sectional size of the shielding member 313 is greater than or equal to the cross-sectional size of the perforation 21 , thereby ensuring the shielding effect of the shielding member 313 on the perforation 21 and preventing impurities such as water or dust from outside from entering the heating chamber 11 through the perforation 21 .

[0057] Please continue reading Figures 2 to 4 In some embodiments, when the cover body 20 is in the first state, if the shielding member 313 rotates relative to the cover body 20 along the first direction X to open the through-hole 21, the shielding member 313 can drive the detected member 315 to rotate so that the detected member 315 enters the detection range of the detection member 33; if the shielding member 313 rotates relative to the cover body 20 along the second direction Y to block the through-hole 21, the detected member 315 exceeds the detection range of the detection member 33. Therefore, when the cover body 20 is in the first state, the detection member 33 can detect the detected member 315 to confirm whether the aerosol generating matrix 200 is accommodated in the heating chamber 11.

[0058] Please combine Figures 5 to 7 In other embodiments, when the cover body 20 is in the second state, no matter whether the shielding member 313 blocks or opens the perforation 21, the detected member 315 is beyond the detection range of the detecting member 33. Thus, when the cover body 20 is in the second state, the detecting member 33 cannot detect the detected member 315 to confirm whether the aerosol generating matrix 200 is accommodated in the heating chamber 11.

[0059] In some embodiments, the detected member 315 may be arranged on the shielding member 313 in a non-detachable connection manner, thereby improving the bonding strength between the detected member 315 and the shielding member 313, preventing the detected member 315 from falling off the shielding member 313 during the rotation of the shielding member 313, thereby ensuring the normal operation of the detection component 30. Among them, the non-detachable connection method includes but is not limited to bonding or welding. In other embodiments, the detected member 315 may be arranged on the shielding member 313 in a detachable connection manner, thereby facilitating the removal of the detected member 315 for repair or replacement when it is damaged, thereby ensuring the normal operation of the detection component 30. Among them, the detachable connection method includes but is not limited to snap connection or threaded connection. It is understandable that the second connecting member 43 may also be arranged on the body 10 in a non-detachable or detachable connection manner.

[0060] In some embodiments, the detection member 33 may be a Hall switch, a photoelectric sensor, or a collision sensor, etc., which is not limited here. The detected member 315 may be a device that can cooperate with the detection member 33 so that the detection member 33 can confirm whether the aerosol generating substrate 200 is accommodated in the heating chamber 11.

[0061] Specifically, in some embodiments, the detection member 33 may be a Hall switch, and the detected member 315 may be a magnetic element (such as a permanent magnet, etc.). The Hall switch is used to detect the magnetic field of the magnetic element to determine whether the perforation is in an open state or a closed state. In other words, the Hall switch can confirm whether the aerosol generating substrate 200 is accommodated in the heating chamber 11 according to the magnetic field of the magnet, and when the aerosol generating substrate 200 is accommodated in the heating chamber 11, the detection member 33 can output a heating signal so that the aerosol generating substrate 200 is heated to generate an aerosol. In other embodiments, the detection member 33 may be one of the transmitting end or the receiving end of the photoelectric sensor, and in this case, the detected member 315 may be the other of the transmitting end or the receiving end, so that the detection member 33 can confirm whether the aerosol generating substrate 200 is accommodated in the heating chamber 11 according to whether the light signal emitted by the transmitting end is received.

[0062] See also Figure 2 and Figure 5 In some embodiments, when the cover 20 is in the second state, the cover 20 is separated from the body 10. Specifically, in some embodiments, when the cover 20 is manually intervened to completely separate the cover 20 from the body 10, the cover 20 is in the second state, in which case the heating chamber 11 is in a fully open state, that is, the heating chamber 11 can communicate with the outside through the opening 13, thereby facilitating the user to clean the heating chamber 11.

[0063] See also Figure 2 , Figure 6 and Figure 7 In other embodiments, when the cover 20 is in the second state, the cover 20 is at least partially connected to the body 10. Specifically, in some embodiments, when the cover 20 is subjected to manual intervention to at least partially separate the cover 20 from the body 10, the cover 20 is in the second state, in which case the heating chamber 11 can also be in a fully open state, that is, the heating chamber 11 can be connected to the outside through the opening 13, thereby facilitating the user to clean the heating chamber 11. In addition, compared with the complete separation of the cover 20 from the body 10, the at least partial connection of the cover 20 with the body 10 can also prevent the cover 20 from being lost, thereby improving the user experience.

[0064] Please combine Figure 6 In some embodiments, the cover 20 can move relative to the body 10 so that the cover 20 opens the opening 13 or aligns the opening 13 with the through-hole 21. Specifically, when the cover 20 is in the first state, the opening 13 can be aligned with the through-hole 21, that is, the central axis of the opening 13 can coincide with the central axis of the through-hole 21, and when the moving part 31 rotates relative to the cover 20, the moving part 31 can block or conduct the communication between the through-hole 21 and the opening 13; when the cover 20 moves (slides) relative to the body 10 to change from the first state to the second state, the cover 20 is at least partially connected to the body 10, and the cover 20 can open the opening 13, the central axis of the opening 13 does not coincide with the central axis of the through-hole 21, and when the moving part 31 rotates relative to the cover 20, the heating chamber 11 can always communicate with the outside through the opening 13.

[0065] Please combine Figure 7 In other embodiments, the cover 20 can rotate relative to the body 10 so that the cover 20 opens the opening 13 or aligns the opening 13 with the through hole 21. Specifically, when the cover 20 is in the first state, the opening 13 can be aligned with the through hole 21, that is, the central axis of the opening 13 can coincide with the central axis of the through hole 21, and when the moving part 31 rotates relative to the cover 20, the moving part 31 can block or conduct the communication between the through hole 21 and the opening 13; when the cover 20 rotates relative to the body 10 (including translation or flipping, etc.) to change from the first state to the second state, the cover 20 is at least partially connected to the body 10, and the cover 20 can open the opening 13, the central axis of the opening 13 does not coincide with the central axis of the through hole 21, and when the moving part 31 rotates relative to the cover 20, the heating chamber 11 can always communicate with the outside through the opening 13.

[0066] See also Figure 2In some embodiments, the aerosol generating device 100 may further include a connecting component 40 (adhesive, screws, buckles, magnets, etc.), and the connecting component 40 is used to connect the body 10 and the cover 20. It should be noted that in some embodiments, the connecting component 40 includes but is not limited to bolts, buckles or magnetic parts, etc.

[0067] Specifically, in some embodiments, the cover 20 and the body 10 can be detachably connected by a connection assembly 40, so that the cover 20 can be switched between a first state and a second state, so that the opening 13 is aligned with the through hole 21 or the cover 20 can open the opening 13. In the case where the cover 20 is connected to the body 10 through the connection assembly 40, the cover 20 is in the first state, and the opening 13 can be aligned with the through hole 21. In this case, the moving part 31 can rotate relative to the cover 20 to block or conduct the communication between the through hole 21 and the opening 13; when the cover 20 is removed from the body 10, the cover 20 changes from the first state to the second state, and the cover 20 can open the opening 13. In this case, when the moving part 31 rotates relative to the cover 20, the heating chamber 11 can always communicate with the outside through the opening 13.

[0068] For further information, please refer to Figure 2 In some embodiments, the connecting assembly 40 includes a first connecting member 41 and a second connecting member 43. The first connecting member 41 is disposed on the cover 20. The second connecting member 43 is disposed in the body 10, and the first connecting member 41 and the second connecting member 43 cooperate to connect the cover 20 to the body 10.

[0069] In some embodiments, the first connector 41 can be arranged on the cover 20 in a non-detachable connection mode, thereby improving the bonding strength between the first connector 41 and the cover 20, preventing the first connector 41 from falling off the cover 20 when the first connector 41 and the second connector 43 are disconnected, thereby improving the stability and reliability of the connection between the cover 20 and the body 10. Among them, the non-detachable connection mode includes but is not limited to bonding or welding. In other embodiments, the first connector 41 can be arranged on the cover 20 in a non-detachable connection mode, thereby facilitating the removal and replacement of the first connector 41 when it is damaged, thereby ensuring the normal connection between the cover 20 and the body 10. Among them, the detachable connection mode includes but is not limited to snap-fit ​​connection or threaded connection. It is understandable that the second connector 43 can also be arranged on the body 10 in a non-detachable or detachable connection mode. Among them, the non-detachable connection mode includes but is not limited to bonding or welding; the detachable connection mode includes but is not limited to snap-fit ​​connection or threaded connection.

[0070] Furthermore, in some embodiments, one of the first connecting member 41 and the second connecting member 43 is a magnetic member, and the other is an adsorbing member, and the magnetic member cooperates with the adsorbing member to connect the cover 20 with the body 10. Specifically, when the first connecting member 41 and the second connecting member 43 are close to each other, the magnetic field of the magnetic member can act on the adsorbing member to generate a suction force on the adsorbing member, and the suction force can connect the cover 20 with the body 10.

[0071] In some embodiments, the adsorbent may be made of iron or soft magnetic material. For example, when the adsorbent is made of soft magnetic material, when the magnetic member is in contact with the adsorbent (including direct contact or indirect contact), the adsorbent can generate a magnetic field under the magnetic field of the magnetic member and attract the magnetic member, thereby achieving the coordination between the adsorbent and the magnetic member, thereby achieving the connection between the cover 20 and the body 10.

[0072] In some embodiments, the magnetic member is disposed on the cover 20 and the adsorption member is disposed on the main body 10, thereby increasing the distance between the magnetic member and the detection member 33 and preventing the magnetic field of the magnetic member from interfering with the detection member 33, thereby improving the accuracy of the detection member 33 in detecting whether the aerosol generating matrix 200 is accommodated in the heating chamber 11.

[0073] In other embodiments, the magnetic member is disposed on the body 10, and the adsorbent is disposed on the cover 20. At this time, in order to prevent the magnetic field of the magnetic member from interfering with the detection member 22, the aerosol generating device 100 may further include a barrier (not shown), which is covered on the magnetic member and used to block the magnetic field of the magnetic member toward the detection member 33, thereby reducing or even preventing the magnetic field of the magnetic member from interfering with the detection member 33, thereby further improving the accuracy of the detection member 33 in detecting whether the aerosol generating matrix 200 is accommodated in the heating chamber 11. It should be noted that in some embodiments, the barrier may be made of materials such as low carbon steel, silicon steel or silicon steel sheet.

[0074] Understandably, please combine Figure 7 In some embodiments, in addition to the first connector 41 and the second connector 43, the connection assembly 40 may further include a third connector (not shown), and the cover 20 is rotatably connected to the body 10 through the third connector. Thus, when the first connector 41 and the second connector 43 are released from engagement, a portion of the structure of the cover 20 can remain connected to the body 10 through the third connector, and the cover 20 can be rotated relative to the body 10 through the third connector to change the cover 20 from the first state to the second state. In this case, the cover 20 opens the opening 13, and the detected member 315 exceeds the detection range of the detection member 33. It should be noted that in some embodiments, the third connector may be a hinge or a rotation, etc., which is not limited here.
