[0039] In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] The present application embodiment provides an electronic atomization device. Figure 1 and Figure 3 As shown, the electronic atomization device 10 in the embodiment of the present application is an electronic cigarette. In other optional embodiments, the electronic atomization device 10 may also be other types of electronic atomization devices, such as a medical electronic atomization device.

[0041] like Figures 1 to 8 As shown, the electronic cigarette includes a housing 100 and a liquid storage chamber 101 , a leak-proof chamber 103 , an air inlet channel 104 , an atomizing core assembly 200 and an airflow sensor 300 arranged in the housing 100 .

[0042] The liquid storage chamber 101 stores the e-liquid. The e-liquid can be directly stored in the liquid storage chamber 101 or stored in a Figure 3 As shown, an oil storage cotton 1011 is placed in the liquid storage chamber 101 , and the tobacco oil is stored in the oil storage cotton 1011 .

[0043] like Figure 3 and Figure 4 As shown, a nozzle 105 is provided on the top of the shell 100, an atomization channel 102 is provided in the liquid storage chamber 101, and the top of the atomization channel 102 is connected to the nozzle 105, so that the aerosol formed by heating and atomizing the tobacco oil is transported from the atomization channel 102 to the nozzle 105.

[0044] Continue to refer Figure 3 and Figure 4 The anti-leakage chamber 103 is arranged below the liquid storage chamber 101, and the bottom end of the atomization channel 102 is connected to the anti-leakage chamber 103, so that the condensed smoke oil in the atomization channel 102 falls into the anti-leakage chamber 103, preventing the condensed smoke oil from leaking to the outside.

[0045] like Figure 3 and Figure 4 As shown, the air inlet channel 104 is disposed on one side of the liquid storage chamber 101. Specifically, as shown in FIG. Figure 3 As shown, the air inlet channel 104 is arranged on the right side of the liquid storage chamber 101. When the electronic cigarette is placed in a different direction, it can also be said that the air inlet channel 104 is arranged on the left side of the liquid storage chamber 101, which depends on the placement of the electronic cigarette. The top of the air inlet channel 104 is connected to the outside atmosphere, and the bottom of the air inlet channel 104 is connected to the anti-leakage chamber 103. When inhaling, refer to Figure 3 , the outside airflow enters from the air inlet channel 104, flows downward into the anti-leakage chamber 103, and then flows upward from the anti-leakage chamber 103 into the atomization channel 102, takes away the aerosol in the atomization channel 102, and then flows out from the mouthpiece 105. In the present application, the air inlet channel is arranged on one side of the liquid storage chamber 101, the top of the air inlet channel 104 is connected to the outside atmosphere, and the bottom of the air inlet channel 104 is connected to the anti-leakage chamber 103, so that the air inlet of the air inlet channel 104 faces upward, instead of being arranged below the liquid storage chamber 101 like in the prior art, with the air inlet facing downward, thereby preventing the smoke oil from leaking from the air inlet channel 104.

[0046] The atomizer core assembly 200 is used to atomize the e-liquid to form an aerosol. The atomizer core assembly 200 can be arranged inside the atomizer channel 102 or below the atomizer channel 102. Figure 3 As shown, the atomizer core assembly 200 is arranged inside the atomization channel 102. In other optional embodiments, if the liquid storage chamber 101 does not use the oil storage cotton 1011 but directly injects the e-liquid into the liquid storage chamber 101 (the e-liquid directly injected into the liquid storage chamber 101 is also called clear oil), the atomizer core assembly 200 can also be arranged below the liquid storage chamber 101, so that the e-liquid is heated and atomized when it flows to the atomizer core assembly 200 below the liquid storage chamber 101, and then the atomized aerosol flows out from the atomization channel 102.

[0047] like Figure 3 As shown, the airflow sensor 300 is arranged above the liquid storage chamber 101. The airflow sensor 300 is used to detect the suction airflow to control the opening and closing of the atomizer core assembly 200. When the user draws air from the mouthpiece 105, the airflow sensor 300 can detect the suction airflow, thereby controlling the atomizer core assembly 200 to power on and start heating and atomization. When the user stops drawing air, the airflow sensor 300 cannot detect the suction airflow, and the atomizer core assembly 200 stops working. In the present application, the airflow sensor 300 is arranged above the liquid storage chamber 101, and the airflow sensor 300 is higher than the atomization channel 102, which prevents the smoke oil in the atomization channel 102 from leaking downward to the airflow sensor 300, damaging the airflow sensor 300 and affecting its accuracy.

[0048] In the present application embodiment, Figure 3 and Figure 4 As shown, the air inlet channel 104 and the atomizing channel 102 both extend in the longitudinal direction, and the air inlet channel 104 and the atomizing channel 102 are arranged in parallel in the longitudinal direction, and the bottom ends of the air inlet channel 104 and the atomizing channel 102 both penetrate the top wall of the anti-leakage cavity 103, so that the air inlet channel 104 and the atomizing channel 102 are both connected to the anti-leakage cavity 103 from the top of the anti-leakage cavity 103, the top end of the air inlet channel 104 penetrates the top of the housing 100, and the top end of the atomizing channel 102 is connected to the suction nozzle 105. Figure 3 The above design enables the air inlet channel 104, the anti-leakage chamber 103 and the atomization channel 102 to roughly form a U-shaped airway structure, which is not only conducive to leakage prevention, but also has a regular structure and is easier to process and assemble.

[0049] like Figure 3 and Figure 5 As shown, a liquid guide structure 1031 is provided in the anti-leakage cavity 103. One end of the liquid guide structure 1031 is located in the anti-leakage cavity 103, and the other end extends into the liquid storage cavity 101, so as to introduce the tobacco oil in the anti-leakage cavity 103 into the liquid storage cavity 101 for further use. As the tobacco oil in the liquid storage cavity 101 is heated and atomized by the atomizer core assembly 200, the tobacco oil in the anti-leakage cavity 103 will be sucked into the liquid storage cavity 101 along the liquid guide structure 1031.

[0050] The liquid conducting structure 1031 may be a cotton strip or other fiber strip, or may be a liquid conducting structure 1031 such as a capillary or a capillary. Figure 5 As shown, a liquid-conducting cotton strip is used, and the two ends of the liquid-conducting cotton strip are respectively connected to the anti-leakage chamber 103 and the liquid storage chamber 101, so that the tobacco oil in the anti-leakage chamber 103 is introduced into the liquid storage chamber 101 for reuse.

[0051] In one embodiment, if Figure 5 As shown, a liquid absorbing member 1032 is provided in the leak-proof cavity 103, and the liquid absorbing member 1032 can absorb the condensed liquid falling into the leak-proof cavity 103. The liquid absorbing member 1032 can be oil-absorbing cotton or other materials that can absorb tobacco oil. Figure 5 As shown, the oil-absorbing cotton is located below the atomization channel 102. When smoke oil falls downward from the atomization channel 102, it will fall onto the oil-absorbing cotton and be absorbed by the oil-absorbing cotton, thereby further reducing the risk of oil leakage.

[0052] Further, such as Figure 5 As shown, the liquid guiding structure 1031 is inserted into the oil-absorbing cotton in the anti-leakage cavity 103 , so that the tobacco oil in the oil-absorbing cotton can be effectively introduced into the liquid storage cavity 101 .

[0053] like Figure 3 and Figure 4As shown, a sensor installation cavity 106 is provided above the liquid storage cavity 101, and the sensor installation cavity 106 is used to install the airflow sensor 300. The sensor installation cavity 106 is connected to the suction nozzle 105, so that the airflow sensor 300 can detect the suction airflow. Figure 3 and Figure 4 , as shown, a main airway 1051 and a sensor airway 1052 are provided in the mouthpiece 105, the main airway 1051 is communicated with the atomization channel 102, and the sensor airway 1052 is communicated with the sensor installation cavity 106. In this way, the sensor airway 1052 is separated from the main airway 1051, which can prevent condensed smoke oil from entering the sensor installation cavity 106 and affecting the airflow sensor 300. At the same time, the separation of the sensor airway 1052 from the main airway 1051 can also improve the detection accuracy of the airflow sensor 300, because the separate setting makes the sensor airway 1052 smaller, and a slight suction can be detected by the airflow sensor 300.

[0054] Continue to refer Figure 3 and Figure 4 A battery cavity 107 is provided on one side of the liquid storage cavity 101 , and the battery cavity 107 is used to install the battery 500 . Figure 3 and Figure 4 In the illustrated embodiment, the battery 500 and the air inlet channel 104 are located on the same side of the liquid storage chamber 101, and specifically, the air inlet channel 104 is located between the liquid storage chamber 101 and the battery 500. In other optional embodiments, the battery 500 and the air inlet channel 104 may also be located on different sides of the liquid storage chamber 101, that is, the battery 500 and the air inlet channel 104 are respectively arranged on both sides of the liquid storage chamber 101.

[0055] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, in the embodiment of the present application, the housing 100 includes an upper housing assembly 110, an oil cup 120 and a liquid storage chamber bottom cover 130. Figure 8 As shown, the upper part of the oil cup 120 is provided with a liquid storage chamber 101 and a battery chamber 107 arranged side by side on the left and right, and the lower part of the oil cup 120 is provided with a leakproof chamber 103. The tops of the liquid storage chamber 101 and the battery chamber 107 are open, and the bottom of the leakproof chamber 103 is open. The upper shell assembly 110 is covered on the upper part of the oil cup 120, thereby closing the tops of the liquid storage chamber 101 and the battery chamber 107, forming a closed battery chamber 107 and liquid storage chamber 101. The liquid storage chamber bottom cover 130 is covered on the lower part of the oil cup 120, thereby closing the bottom of the leakproof chamber 103, forming a closed leakproof chamber 103. By arranging three cavities on the oil cup 120 to form the liquid storage chamber 101, the battery chamber 107 and the leakproof chamber 103, the number of parts is small, the installation is convenient, and the structure is compact.

[0056] Combination Figure 4 and Figure 8An air pipe 1071 is inserted into the battery cavity 107, and the air pipe 1071 forms an air inlet passage 104. Figure 8 As shown, the side wall of the oil cup 120 battery cavity 107 is provided with an air pipe 1071 installation position a, and the air pipe 1071 is fixed by providing corresponding installation ribs 1072 and installation columns 1073 at the installation position of the air pipe 1071. The installation column 1073 is designed to be hollow, and the hollow structure is connected to the anti-leakage cavity 103. After the air pipe 1071 is inserted into the installation column 1073, it can be connected to the anti-leakage cavity 103. Figure 4 As shown, the top end of the air pipe 1071 is inserted into the top wall of the housing 100 and communicates with the outside atmosphere, and the bottom end of the air pipe 1071 is inserted into the bottom wall of the battery cavity 107 and communicates with the anti-leakage cavity 103. In this way, the air pipe 1071 is inserted into the battery cavity 107 to form the air inlet channel 104, and there is no need to form the air inlet channel 104 on the oil cup 120 by injection molding, which simplifies the structure of the oil cup 120 and reduces the difficulty of molding.

[0057] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the upper shell assembly 110 includes an upper shell 111, a sensor mounting member 112 and a mounting seat 113. The suction nozzle 105 is arranged on the upper shell 111. The sensor mounting member 112 and the mounting seat 113 are arranged below the suction nozzle 105 in sequence, and a sensor mounting cavity 106 is formed between the sensor mounting member 112 and the mounting seat 113. The mounting cavity is connected to the suction nozzle 105, specifically, it is connected to the sensor airway 1052 in the suction nozzle 105. Specifically, as shown in FIG. Figure 7 As shown, the bottom end surface of the sensor mounting member 112 is recessed upward to form the sensor mounting cavity 106, and the mounting seat 113 is covered at the bottom end of the sensor mounting member 112 to close the bottom end of the sensor mounting cavity 106. Figure 3 The top end of the sensor installation cavity 106 is connected to the sensor air passage 1052 of the suction nozzle 105 .

[0058] like Figure 3 As shown, the main airway 1051 of the suction nozzle 105 is roughly arranged at the center of the suction nozzle 105, and the sensor airway 1052 is arranged on one side of the main airway 1051. At the same time, the sensor installation cavity 106 is also arranged on one side of the main airway 1051, so that the sensor airway 1052 and the sensor installation cavity 106 are arranged correspondingly up and down, which is conducive to the communication between the sensor installation cavity 106 and the sensor airway 1052. The sensor installation cavity 106 is arranged on one side of the main airway 1051, which also keeps the airflow sensor 300 away from the main airway 1051, thereby preventing the smoke oil from leaking to the airflow sensor 300.

[0059] like Figure 3 and Figure 6As shown, the housing 100 further includes a lower housing 140. The lower housing 140 is disposed on the bottom of the oil cup 120, and there is a gap between the lower housing 140 and the liquid storage chamber bottom cover 130, and the gap forms a mounting cavity. Figure 3 As shown, the PCB circuit board 400 can be installed in this installation cavity.

[0060] like Figure 3 As shown, in the embodiment of the present application, the atomizer core assembly 200 includes a mounting tube 210, an oil-guiding cotton 220, and a heating element 230. The atomization channel 102 is formed in the mounting tube 210. The oil-guiding cotton 220 is disposed in the mounting tube 210, and the heating element 230 is disposed in the oil-guiding cotton 220. Figure 6 As shown, the side wall of the mounting tube 210 is provided with an oil guide hole 211, and the oil guide cotton 220 is connected to the liquid storage chamber 101 through the oil guide hole 211, so that the tobacco oil in the liquid storage chamber 101 enters the oil guide cotton 220 through the oil guide hole 211. The heating element 230 in the oil guide cotton 220 is connected to the battery 500 of the electronic cigarette, so that the battery 500 supplies power to the heating element 230, and the heating element 230 is powered on to generate heat, heating the tobacco oil in the oil guide cotton 220 to form an aerosol. When inhaling, the aerosol is sucked away along the atomization channel 102. The heating element 230 can adopt a resistance heating structure such as a resistance heating wire and a heating net.

For ordinary technicians in this field, the meanings of the above terms in this application can be understood according to specific circumstances.

[0062] In the description of this embodiment, the terms "upper", "lower", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
