Detailed Description
In this application, it is to be understood that terms such as "including" or "having" are intended to indicate the presence of the disclosed features, numbers, steps, acts, components, parts, or combinations thereof, and are not intended to preclude the presence or addition of one or more other features, numbers, steps, acts, components, parts, or combinations thereof.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
The application is further described with reference to examples of embodiments shown in the drawings.
The present application provides a nozzle assembly having an air path channel 120 and a capacitive element 110 surrounding the air path channel 120. Referring to fig. 1, the mouthpiece assembly may be used in an electronic cigarette 100.
When the user's mouth wraps around the nozzle assembly, this causes a change in the capacitance value presented by the internal capacitive element 110. The control module 140 in the electronic cigarette 100 can determine whether the user is smoking only by detecting the capacitance of the capacitive element 110, and then start the smoke cartridge module 130 to heat the smoke liquid therein.
Referring to fig. 1 and 2, the capacitive element 110 includes: a first ring electrode 112 surrounding the air passage 120 (i.e., the inner hollow region of the capacitive element 110), a second ring electrode 114 surrounding the first ring electrode 112, and an insulating elastic member 113 a; the first annular electrode 112 is fixedly arranged relative to the air passage 120, the first annular electrode 112 and the second annular electrode 114 are separated from each other, the distance between the second annular electrode 114 and the first annular electrode 112 is adjustable, and the insulating elastic pieces 113a are respectively connected with the first annular electrode 112 and the second annular electrode 114; when the first and second ring electrodes 112 and 114 approach each other to press the insulating elastic member 113a, the insulating elastic member 113a is elastically deformed.
When the user's mouth wraps around the nozzle assembly, slight pressure needs to be applied to the nozzle assembly, causing the distance between the second ring electrode 114 and the first ring electrode 112 to become smaller, which in turn causes the capacitance formed therebetween to become larger. When the user releases the mouth, the insulating elastic member 113a separates the first ring electrode 112 and the second ring electrode 114, and the capacitance formed therebetween becomes small.
Of course, both the first ring electrode 112 and the second ring electrode 114 are not in contact.
In order to adjust the distance between the first ring electrode 112 and the second ring electrode 114, the second ring electrode 114 may be a deformable and recoverable thin metal material, or may be a ring shape having a gap (i.e., the angle enclosed by the second ring electrode is less than 360 °), or the second ring electrode 114 may be a multi-segment ring electrode divided into a plurality of segments with a certain gap therebetween.
Optionally, the nozzle assembly further comprises: the first insulating protective layer 115a surrounds the second ring electrode 114, and the first insulating protective layer 115a is deformable. The first insulating protective layer 115a is used to protect the second ring electrode 114, and should be formed of a deformable material, such as an elastic polymer, or a non-elastic polymer, and may not be a hard non-deformable material such as glass or ceramic.
Optionally, the material of the first ring electrode 112 and/or the second ring electrode 114 includes: a metal.
Alternatively, the material of the insulating elastic member 113a includes: a polymer. I.e., a resilient polymer mass, or a resilient polymer ring, is disposed between the first ring electrode 112 and the second ring electrode 114. Of course, the insulating elastic member 113a may also be a U-shaped elastic sheet, the top end of the elastic sheet may be fixed to a fixed component inside the electronic cigarette (for example, the inner wall of the electronic cigarette or the outer wall of the cartridge module 130), and two ends of the elastic sheet are respectively connected to the first annular electrode 112 and the second annular electrode 114.
Optionally, the nozzle assembly further comprises a second insulating protective layer 111 on the inner surface of the first ring electrode 112. The second insulating protective layer 111 functions to prevent the first ring electrode 112 from being corroded by the fumes and the liquid resulting from condensation of the fumes.
Optionally, the material of the second insulating protection layer 111 includes: glass or rigid plastic. The shape of the second insulating protective layer 111 should be kept stable, thereby ensuring the shape of the first ring-shaped electrode 112 to be stable.
Optionally, the nozzle assembly further comprises a removable elastic protective sleeve (not shown) surrounding the capacitive element 110. If the user who need change the suction, only need to change can to dismantle the elastic protection cover. Therefore, the multi-user shared suction can be realized, and the sanitation is kept.
Referring to fig. 3 and 4, in another embodiment, the capacitive element 110 includes: a first ring electrode 112 surrounding the air passage 120 (i.e., the inner hollow region of the capacitive element 110), a second ring electrode 114 surrounding the first ring electrode 112, an insulating filling layer 113 between the first ring electrode 112 and the second ring electrode 114, a third insulating protective layer 115 surrounding the second ring electrode 114, and a plurality of electrode blocks 116 embedded in the third insulating protective layer 115; the first ring electrode 112 and the second ring electrode 114 are separated from each other.
Capacitances can be formed among the first ring electrode 112, the second ring electrode 114 and the electrode block 116. When the user's mouth completely encloses the nozzle assembly, a capacitance can also be formed between the user's mouth and each electrode block 116. This causes a change in the equivalent capacitance between first ring electrode 112 and second ring electrode 114. Based on this change in equivalent capacitance, the control module 140 may determine whether the user is pumping. And a sufficiently large change in capacitance can only be made when the user's mouth completely encloses all of the electrode blocks 116. If the other parts of the body touch the suction nozzle assembly by mistake, only a small amount of the electrode blocks 116 form capacitance with the other parts, and the change amount of the overall capacitance is small. Based on this, the false touch prevention can be realized.
Alternatively, referring to fig. 4, the plurality of electrode blocks 116 are ring-level and evenly distributed around the second ring electrode 114.
Referring to fig. 1, an embodiment of the present application provides an electronic cigarette 100 including a control module 140, a cartridge module 130, and the above-mentioned mouthpiece assembly; the control module 140 is configured to detect a capacitance value of the capacitive element 110, and control the cartridge module 130 to start heating the liquid in the cartridge module 130 according to the capacitance value of the capacitive element 110.
In particular, the control module 140 should contain capacitance measurement circuitry as well as logic control circuitry. The cartridge module 130 should contain a heating element and a liquid storage chamber that contains liquid. The specific form of the control module 140 and the cartridge module 130 is not limited by this application. The power supply 150 provides power to the control module 140 and the cartridge module 130.
The embodiments in the present application are described in a progressive manner, and the same and similar parts among the embodiments can be referred to each other, and each embodiment focuses on the differences from the other embodiments.
