[0025] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0026] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] HNB e-cigarette, the full name of which is heat-not-burn e-cigarette, is a new type of tobacco product similar to traditional tobacco products. Its working principle is to use the external heat source of the e-cigarette device to heat the special tobacco ingredients at low temperature instead of burning them, so as to release smoke for people to inhale. Compared with ordinary cigarettes, it produces relatively fewer harmful substances.

[0029] However, most of the current e-cigarette products have the characteristics of compact structure, a wide variety of components, and a long assembly process. The product assembly efficiency is low and it is difficult to ensure its assembly quality. In addition, during the use of most e-cigarette products, users cannot judge whether the cigarette cartridge has been used up, and cannot provide users with a good smoking experience.

[0030] Based on this, the embodiment of the utility model provides an electronic cigarette device, which can improve assembly efficiency, reduce production costs and enhance user experience.

[0031] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings.

[0032] Reference Figure 1 , Figure 4 , the utility model provides an electronic cigarette device, comprising: a first shell 100 and a heating module 200;

[0033] The first housing 100 is provided with a receiving cavity 110 therein;

[0034] The heating module 200 can be removably installed inside the accommodating cavity 110. The heating module 200 includes a second shell 210, a heating module, an airflow detection module 250 and a bottom cover connected to the bottom of the second shell 210. The heating module is embedded in the second shell 210, and the airflow detection module 250 is located at the lower end of the heating module and fixedly installed on the bottom cover.

[0035] According to an electronic cigarette device provided by an embodiment of the utility model, a heating module and an airflow detection module 250 are integrated in a second shell 210 to form a heating module 200, and the heating module 200 is detachably installed inside the receiving cavity 110. Compared with the technical solution of separately installing the heating module and the airflow detection module 250 in the first shell 100, the integrated setting of the heating module and the airflow detection module 250 optimizes the internal structure of the electronic cigarette, making the overall design more compact and efficient, reducing the connection between components, thereby simplifying the assembly and maintenance process of the electronic cigarette, and at the same time, better improving the stability of the device operation, reducing the risk of failure caused by loose or damaged components, by arranging the airflow detection module 250 below the heating module, the user's inhalation action can be detected more accurately, once the inhalation is detected, the heating module can respond quickly and start the heating process, in addition, by arranging the airflow detection module 250, it can also indirectly assist the device in counting the number of puffs of the user, so that the user can obtain information on the number of puffs of the electronic cigarette, which helps the user to judge whether the cigarette cartridge has been puffed, and better improves the user experience.

[0036] It should be noted that since the heating module 200 can be detachably installed inside the accommodating cavity 110, when some components in the heating module 200 or other components in the first shell 100 fail, resulting in the user being unable to inhale normally, the fault location can be quickly determined by replacing the heating module 200. In addition, if it is determined that only the heating module 200 or only other components in the first shell 100 fail, and the failed components are difficult to repair, the components that have not failed can be installed in new accessories and continue to be used, which greatly saves maintenance costs and improves maintenance efficiency.

[0037] It should be noted that an air inlet is provided at the bottom of the heating module, and the airflow detection module 250 is located at the lower end of the heating module. The airflow detection module 250 is closer to the air inlet at the lower end of the heating module, and is more sensitive to the detection of the suction behavior and has higher detection accuracy. In addition, compared with the technical solution of adding an air inlet duct below the air inlet hole of the heating module and setting the airflow detection module 250 at the air inlet of the air inlet duct, the heating module 200 lacks the setting of the air inlet duct, which effectively reduces the overall volume of the heating module 200, and then reduces the overall volume of the electronic cigarette device. On the whole, it saves production costs while improving the accuracy of detection.

[0038] It should be noted that when the heating module 200 is installed in the accommodating cavity 110, the wiring terminals arranged on the outside of the second shell 210 are also inserted into the preset connection ports in the accommodating cavity 110. Compared with the technical solution of separately installing the heating module and the airflow detection module 250 in the first shell 100, there is no need to consider the winding method of the electrical connection lines of the heating module and the airflow detection module 250 during the installation process, which greatly improves the assembly efficiency. On the whole, the wiring method is simple and not easy to disconnect, the power supply is more stable and reliable, and the problem of poor power supply of the heating module 200 is avoided.

[0039] Reference Figure 4 In some embodiments, the heating module includes a heating bracket 221, a heating element 222 and a connecting pipe 223. The heating bracket 221 is embedded in the second shell 210, the heating element 222 is embedded in the heating bracket 221, the connecting pipe 223 is partially embedded in the heating element 222, and the upper end of the connecting pipe 223 extends to the outside of the second shell 210.

[0040] It should be noted that an air inlet is also provided at the bottom of the heating element 222, and the cigarette cartridge is embedded in the connecting tube 223. The heating element 222 can heat the cigarette cartridge embedded in the connecting tube 223 at a low temperature. When the user inhales from the upper end of the connecting tube 223, the gas can enter through the air inlet at the bottom of the heating element 222, and flow through the gap between the connecting tube 223 and the cigarette cartridge, and mix to form smoke.

[0041] In some embodiments, the bottom cover includes a bottom cover support plate 231, a columnar body 232 located above the bottom cover support plate 231, and a box body 233 located below the bottom cover support plate 231. The columnar body 232 is connected to the bottom of the second shell 210 by interference fit. The box body 233 is used to install the airflow detection module 250. The bottom cover support plate 231 is provided with a first ventilation hole 310, and the first ventilation hole 310 is connected to the bottom of the heating element 222. The bottom of the box body 233 is provided with a second ventilation hole 320, and the second ventilation hole 320 is connected to the outside, and the second ventilation hole 320 is located directly below the first ventilation hole 310.

[0042] It can be understood that the columnar body 232 above the bottom cover support plate 231 is connected to the bottom of the second shell 210 by interference fit, and the box body 233 below the bottom cover support plate 231 is used to install the airflow detection module 250. Such a structure can provide good support for the heating module and the airflow detection module 250, and prevent the components in the heating module 200 from loosening or being damaged due to vibration or falling.

[0043] It is understandable that when the user inhales from the upper end of the connecting tube 223, the gas enters the interior of the box body 233 from the second air vent 320 at the bottom of the box body 233, and the air flow detection module 250 located inside the box body 233 can detect the air pressure changes inside the box body 233. Furthermore, the gas flows from the inside of the box body 233 through the second air vent 320 into the air inlet at the bottom of the heating element 222, and flows through the gap between the connecting tube 223 and the cigarette cartridge to mix and form smoke.

[0044] Reference Figure 2 , Figure 3 , Figure 4 In some embodiments, the bottom cover further includes a seal 240, which is built into the box body 233. An installation cavity is formed in the seal 240, and the installation cavity is connected to the first vent hole 310 and the second vent hole 320. The airflow detection module 250 is disposed in the installation cavity.

[0045] It can be understood that by setting a seal 240 in the box body 233 and forming an installation cavity in the seal 240, the design of the installation cavity provides a stable working environment for the airflow detection module 250, further limits the flow area of ​​the airflow inside the box body 233, and ensures that the airflow detection module 250 is in contact with the flow area of ​​the airflow inside the box body 233, so that the airflow detection module 250 can more accurately detect the changes in the airflow flowing through the first air hole 310 and the second air hole 320.

[0046] Reference Figure 3 , Figure 4 In some embodiments, the heating module 200 further includes a positioning block 260 , which is connected to the bottom cover, and a card interface 161 matching the positioning block 260 is provided in the receiving cavity 110 .

[0047] Preferably, the positioning block 260 is vertically connected to the bottom cover support plate 231 .

[0048] It should be noted that the card interface 161 is disposed on the main support 160 inside the receiving cavity 110 .

[0049] It should be noted that a plurality of circular holes 261 are provided on the positioning block 260. When the heating module 200 is installed in the receiving cavity 110 provided inside the first shell 100, the lower end of the positioning block 260 is inserted into the card interface 161. There are a plurality of protrusions in the card interface 161 that cooperate with the circular holes 261. Through the mutual cooperation between the circular holes 261 and the protrusions, the heating module 200 can be stably fixed in the receiving cavity 110.

[0050] Reference Figure 4In some embodiments, the heating module further includes a heating coil 224 and a magnetic isolation component 225 . The heating coil 224 is embedded in the gap between the heating bracket 221 and the second shell 210 , and the magnetic isolation component 225 is located in the gap between the heating coil 224 and the second shell 210 .

[0051] It is understandable that the heating bracket 221, as a structural component supporting the heating coil 224, ensures the stability and safety of the coil. It can fix the coil in the correct position to prevent it from moving or deforming during operation. At the same time, the heating bracket 221 also has a certain heat dissipation function, which can help the coil maintain an appropriate temperature during the heating process to prevent overheating damage.

[0052] It should be noted that since the heating coil 224 generates a magnetic field when working, if there are no appropriate isolation measures, these magnetic fields may interfere with other electronic components of the electronic cigarette, such as the airflow detection module 250 or the control chip. The magnetic isolation part 225 is located in the gap between the heating coil 224 and the second shell 210, which can effectively isolate the magnetic field and prevent it from interfering with other components, thereby ensuring the stable operation of the electronic cigarette.

[0053] Reference Figure 1 In some embodiments, it also includes a battery module 150, a PCBA board 120, a display module and a button 130. The PCBA board 120 and the battery module 150 are both arranged in the first shell 100. The button 130 and the display module are both arranged on the side of the first shell 100. The PCBA board 120 is electrically connected to the heating module, the display module, the battery module 150, the button 130 and the airflow detection module 250 respectively.

[0054] It should be noted that when the airflow detection module 250 detects the user's smoking behavior, the control chip above the PCBA board 120 receives the transmission signal of the airflow detection module 250 and records the number of puffs, and the control chip controls the display module to display relevant information.

[0055] It should be noted that the display module can directly display the number of puffs of the electronic cigarette through digital information or display some prompt symbols to remind the user that the cigarette cartridge is about to be puffed out.

[0056] Preferably, the airflow detection module 250 is a microphone.

[0057] Reference Figure 5 The control chip on the PCBA board 120 is electrically connected to the battery module 150, the heating coil 224, the button 130 and the airflow detection module 250 respectively.

[0058] It should be noted that when the microphone assembly detects the user's smoking behavior, the control chip provides greater power to the heating coil 224 to maintain the heating element running stably at the set temperature, maintain a good taste, and improve the user experience. In addition, when the set number of puffs is drawn, the control chip will automatically shut down and disconnect the electrical connection with the battery module 150, which can better avoid the waste of electrical energy.

[0059] It is understandable that the display module can also help users intuitively obtain the working status and power information of the electronic cigarette.

[0060] Reference Figure 1 In some embodiments, an upper cover 170 is further included. The upper cover 170 is located above the first shell 100 . The upper cover 170 has a first opening corresponding to the charging port of the battery module 150 and a second opening adapted to the top of the heating module 200 .

[0061] It should be noted that the upper cover 170 located above the first shell 100 is detachably connected to the first shell 100. After the heating module 200, the battery module 150, the PCBA board 120, the display module, the button 130 and other components are installed in the first shell 100, the upper cover 170 is fixedly connected to the first shell 100.

[0062] It should be noted that the inner diameter of the second opening is consistent with the outer diameter of the connecting tube 223 in the heating module 200. Through the interaction between the upper cover 170 and the card interface 161 located inside the accommodating cavity 110, the heating module 200 can be more stably fixed in the first shell 100.

[0063] Reference Figure 1 In some embodiments, the display module includes an LCD display screen 141 and a lens 142 located outside the LCD display screen 141 .

[0064] It is understandable that the lens 142 is located outside the LCD display screen 141, which can prevent the display screen from being damaged by scratches, impacts, etc., and can also prevent dust and dirt from entering the interior of the display screen, thereby extending the service life of the display screen.

[0065] Reference Figure 1 In some embodiments, a dust cover 171 is further provided above the first opening.

[0066] It can be understood that the dust cover 171 can effectively prevent dust, dirt or other impurities from entering the charging port, keeping the charging port clean and in good working condition, which not only extends the service life of the charging port, but also avoids charging problems caused by blockage or damage of the charging port, thereby improving the reliability and durability of the electronic cigarette.

[0067] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
