Detailed implementation manners

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0028] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] Refer to Figures 1 to 3 , an embodiment of this application provides an e-cigarette that prevents oil leakage, including an atomizer 100, a solenoid valve 200, and a controller 300; an atomization chamber 110 is provided in the atomizer 100; the solenoid valve 200 is provided in the atomizer 100; a liquid passage 210 communicating with the atomization chamber 110 is formed in the solenoid valve 200; one side of the liquid passage 210 away from the atomization chamber 110 is used to communicate with a liquid storage container 400; the controller 300 is provided in the atomizer 100; the controller 300 is electrically connected to the solenoid valve 200 and is used to control the solenoid valve 200 to open or close the liquid passage 210.

[0030] Understandably, when the controller 300 controls the solenoid valve 200 to open the liquid passage 210, the atomization chamber 110 communicates with the liquid storage container 400. At this time, the e-liquid stored in the liquid storage container 400 can enter the atomization chamber 110 and be atomized by the atomization core 170 in the atomizer 100 to generate smoke. When the controller 300 controls the solenoid valve 200 to close the liquid passage 210, the atomization chamber 110 and the liquid storage container 400 are not in communication with each other, thus forming isolation between the atomization chamber 110 and the liquid storage container 400. In this way, by the coordinated control of the solenoid valve 200 and the controller 300 to connect or disconnect the atomization chamber 110 and the liquid storage container 400, on the one hand, the automated control of the connection or disconnection between the atomization chamber 110 and the liquid storage container 400 is realized, further improving the convenience of use for users. On the other hand, the connection between the atomization chamber 110 and the liquid storage container 400 is controlled only when using the electronic cigarette, avoiding the occurrence of oil leakage.

[0031] Furthermore, the above-mentioned controller 300 can be a processor, a single-chip microcomputer or other data processing chips. Correspondingly, the above-mentioned electronic cigarette further includes a circuit board, and the circuit board has a control circuit for enabling the controller 300 to control the solenoid valve 200 to open or close the liquid passage 210.

[0032] In some embodiments, the electronic cigarette further includes a liquid storage container 400 provided in the atomizer 100; the atomizer 100 includes a first housing 120, the atomization chamber 110 is opened in the first housing 120, and the solenoid valve 200 is installed on the first housing 120; the liquid storage container 400 is detachably installed on the first housing 120.

[0033] Understandably, the liquid storage container 400 is detachably installed on the first housing 120, so that it can be replaced after the liquid storage container 400 is used up, improving the convenience of use of the electronic cigarette; secondly, when replacing the liquid storage container 400, the controller 300 can be used to control the solenoid valve 200 to close the liquid passage 210, thus avoiding the phenomenon of oil leakage when replacing the liquid storage container 400.

[0034] Furthermore, the detachable connection between the liquid storage container 400 and the first housing 120 includes but is not limited to threaded connection, snap connection, plug-in connection, mortise and tenon connection, etc.

[0035] Furthermore, the above-mentioned liquid storage container 400 is an oil storage bottle.

[0036] In some embodiments, the liquid channel 210 is disposed through the solenoid valve 200 along the length direction thereof; in the length direction of the solenoid valve 200, one end of the solenoid valve 200 is disposed in the atomization chamber 110, and the other end of the solenoid valve 200 is disposed in the liquid storage container 400. Thus, the inlet end and the outlet end of the liquid channel 210 are respectively located in the liquid storage container 400 and the atomization chamber 110, facilitating the liquid channel 210 to convey the e-liquid in the liquid storage container 400 to the atomization chamber 110.

[0037] In some embodiments, the first housing 120 is provided with a wire channel 121 for the wire of the solenoid valve 200 to pass through. The wire channel 121 communicates with the atomization chamber 110, and the diameter of the wire channel 121 is configured to match the diameter of the wire of the solenoid valve 200. Thus, when the wire of the solenoid valve 200 is passed through the wire channel 121 and electrically connected to the controller 300, the gap between the inner wall of the wire channel 121 and the wire of the solenoid valve 200 can be reduced, thereby reducing the leakage of the e-liquid in the atomization chamber 110 from the wire channel 121.

[0038] In some embodiments, the atomizer 100 further includes a second housing 130 and an electrical connector 140. The first housing 120 and the second housing 130 enclose a receiving cavity 150, and the receiving cavity 150 communicates with the atomization chamber 110 through the wire channel 121. The electrical connector 140 is disposed in the receiving cavity 150, and the electrical connection end of the electrical connector 140 is disposed outside the second housing 130. The wire of the solenoid valve 200 is electrically connected to the electrical connector 140 through the wire channel 121, and the controller 300 is electrically connected to the electrical connection end of the electrical connector 140. Thus, the atomizer 100 serves as an independent module in the electronic cigarette. The atomizer 100 can be electrically connected to the controller 300 in the electronic cigarette by using the electrical connector 140 thereon to control the on / off of the liquid channel 210 in the solenoid valve 200 and / or the start / stop of the atomization core 170 in the atomizer 100, thereby modularizing the devices inside the electronic cigarette, facilitating maintenance and repair, and effectively improving the compactness of the structure of the electronic cigarette.

[0039] In some embodiments, the atomizer 100 further includes a liquid absorption member 160, and the liquid absorption member 160 is disposed in the receiving cavity 150. At least a part of the orthographic projection of the wire channel 121 near the receiving cavity 150 is located on the liquid absorption member 160. Thus, the liquid absorption member 160 can absorb the e-liquid leaking from the wire channel 121, thereby preventing the e-liquid from affecting other components.

[0040] Further, the above liquid absorption member 160 can be absorbent cotton, absorbent felt, absorbent paper, etc., which is not specifically limited herein.

[0041] In some embodiments, the electrical connector 140 is disposed offset from one end of the wire channel 121 near the accommodating cavity 150. In this way, it is possible to prevent the e-liquid leaking out of the wire channel 121 from directly dripping onto the electrical connector 140, thereby improving the use stability and service life of the electrical connector 140.

[0042] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The preferred embodiments of the present application are shown in the drawings, but do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing specific embodiments, or perform equivalent replacements on some of the technical features. Any equivalent structure made by using the specification and drawings of the present application, directly or indirectly applied in other related technical fields, is equally within the scope of the patent protection of the present application.
