DETAILED DESCRIPTION

[0035] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0037] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0038] In the description of the present application, it should be noted that, if the terms "upper", "lower", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly placed when the product of the present application is used, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the present application.

[0039] In addition, if the terms "first", "second" and the like appear, they are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0040] It should be noted that, in the case of no conflict, the features in the embodiments of the present application can be combined with each other.

[0041] In the related art, only a single atmospheric pressure cavity or negative pressure cavity is arranged at the airflow sensor in the atomization device, for enabling the airflow sensor to detect the situation in the atomization channel, so that the atomization device can be started in time when the user inhales through the atomization channel. However, the single atmospheric pressure cavity or negative pressure cavity arranged in this way can easily affect the detection accuracy of the airflow sensor. For example, when the user shakes the atomization device or the atomization device is blown by the wind from the outside, the atmospheric pressure cavity or negative pressure cavity of the airflow sensor will be affected, causing the airflow sensor to send a signal to control the atomization device to start, which can easily cause the atomization device in the related art to start automatically, resulting in waste or leakage of the atomization substrate and affecting the user experience.

[0042] In the related art, some atomization devices adopt the way of adjusting the threshold value of the signal sent by the airflow sensor to avoid the above-mentioned automatic starting. However, this way can also cause the user to need to inhale with force when using the device, and normal inhalation cannot start the atomization device, which can also affect the user experience.

[0043] In order to solve the above-mentioned problems in the related art, the present application provides an atomization device.

[0044] Please refer to Figure 1 、 Figure 2 , for example, the atomization device includes a shell 100 and an airflow sensor 300. The shell 100 includes a detection air channel 110 and a balance air channel 120; the shell 100 is provided with an atomization assembly 200, and the atomization assembly 200 includes an atomization channel 210. The airflow sensor 300 is arranged in the shell 100, and the airflow sensor 300 includes a sensing surface and a balance surface, and the sensing surface and the balance surface are not in communication with each other. The detection air channel 110 is in communication with the atomization channel 210, and the sensing surface is located in the detection air channel 110. The balance air channel 120 is in communication with the outside, and the balance surface is located in the balance air channel 120. An electric control element 400 is arranged in the shell 100, the airflow sensor 300 is arranged on the electric control element 400, the balance air channel 120 is arranged between the airflow sensor 300 and the electric control element 400, and a mounting position corresponding to the position of the balance surface on the electric control element 400 is arranged as a mounting position, and the mounting position is not opened.

[0045] Specifically, in the use of the atomization device of the present application, the sensing surface of the airflow sensor 300 is not in communication with the balance surface, the sensing surface is located in the detection air channel 110, and the detection air channel 110 is in communication with the atomization channel 210. The balance surface of the airflow sensor 300 is located in the balance air channel 120, and the balance air channel 120 is in communication with the external atmosphere, and the two will not affect each other. In the use of the atomization device provided by the present application, the user inhales the atomized substrate from the atomization channel 210, and the airflow in the atomization channel 210 and the detection air channel 110 will change, that is, the data detected by the sensing surface of the airflow sensor 300 will change, while the balance surface of the balance air channel 120 will remain unchanged, that is, the data detected by the sensing surface and the balance surface of the airflow sensor will be different, and the airflow sensor 300 will send a signal to control the atomization assembly 200 to start the atomization operation, and the atomization device of the present application will start the operation for the user to use.

[0046] The electric control element 400 is arranged near the balance surface, which facilitates the electrical connection between the airflow sensor 300 and the electric control element 400, and makes the structure of the present application more reasonable. In addition, the position corresponding to the balance surface on the electric control element 400 is not holed, and the balance air channel 120 is sealed and limited by the electric control element 400, so as to avoid the air leakage of the electric control element 400 and affect the normal work of the balance air channel 120.

[0047] It should be noted that in the use of the atomization device of the present application, the data detected by the sensing surface in the first detection channel may change when the user shakes or the external wind blows, but the balance surface can detect the external atmosphere through the balance air channel 120, that is, the data detected by the sensing surface and the balance surface changes synchronously, and there is no pressure difference between the sensing surface and the balance surface. The airflow sensor 300 will not send a signal, which will cause the atomization device to start incorrectly, avoid the waste or leakage of the atomized substrate in the atomization device, and prolong the service life of the atomization device of the present application.

[0048] It can be understood that the atomization device provided by the present application does not have the problem of incorrect start, and there is no need to change the sensing threshold of the airflow sensor 300. Compared with the related art, the sensing threshold of the airflow sensor 300 is increased to avoid the incorrect start of the atomization device, and the atomization device of the present application can be normally used by the user with normal suction, without the need for forced suction, which ensures the use experience of the user.

[0049] In some embodiments, the housing 100 is provided with a buffer element 420, which abuts the side of the electric control element 400 away from the balance surface. The projection area of the buffer element 420 in the axial direction of the atomization device is greater than the projection area of the installation position in the axial direction of the atomization device. By blocking the side of the electric control element 400 with the buffer element 420, the balance air channel 120 is prevented from communicating through other parts of the electric control element 400, thereby affecting the normal operation of the balance air channel 120. In addition, the buffer element 420 can also effectively prevent the electric control element 400 from being damaged during installation by colliding with other components below, thereby facilitating production and reducing the installation difficulty of the present application.

[0050] The buffer element 420 is provided corresponding to the balance surface, and the projection area of the buffer element 420 in the axial direction of the atomization device is greater than the projection area of the installation position in the axial direction of the atomization device. By blocking the electric control element 400 with the buffer element 420, the buffer element 420 can prevent the balance air channel 120 near the balance surface from leaking, thereby further ensuring the accuracy of the detection results of the balance surface and preventing the balance surface from being affected by other factors.

[0051] The buffer element 420 can be any structure with buffering capability, and the present application does not limit it. For example, the buffer element 420 is made of polyvinyl chloride foam (PVC cotton), which has the characteristics of anti-static, good toughness, corrosion resistance, and heat insulation, and can reliably and effectively separate and protect the circuit board and power components.

[0052] In some embodiments, the balance air channel 120 includes a first air path 121, and the balance surface is located in the first air path 121. The housing 100 is further provided with a first frame body 510, which cooperates with the electric control element 400 to form the first air path 121. The first frame body 510 is provided with an air path plate 511, and the first air path 121 communicates with the outside of the atomization device through the air path plate 511. The balance surface communicates with the outside through the first air path 121 and the air path plate 511, so that the balance surface can be used as a reference to detect the external atmospheric conditions, thereby improving the sensitivity and accuracy of the airflow sensor 300 of the present application.

[0053] In some embodiments, the first frame body 510 is provided with a cavity 515, and the airflow sensor 300 is installed in the cavity 515. The air path plate 511 is provided with an air hole 512 and a communication groove 516, and the communication groove 516 is arranged between the air hole 512 and the cavity 515, and the communication groove 516 communicates with the air hole 512 and the cavity 515. By connecting the cavity 515 and the air hole 512 through the communication groove 516, the balance surface in the cavity 515 can communicate with the outside through the communication groove 516 and the air hole 512, so that the balance surface can detect the external airflow in real time.

[0054] In some embodiments, the housing 100 further comprises a second frame 520, and the second frame 520 is provided with a receiving groove 523. The air path plate 511 is inserted into the receiving groove 523, and a gap is arranged between the air path plate 511 and the receiving groove 523 to cooperate to form a gas exchange groove 524 in communication with the outside, and the air hole 512 is in communication with the gas exchange groove 524. The air path plate 511 is inserted into the receiving groove 523, that is, the first frame 510 is inserted into the receiving groove 523 of the second frame 520, and the relative position of the first frame 510 and the second frame 520 is limited by the receiving groove 523, which reduces the installation difficulty of the first frame 510 and the second frame 520, and makes the application easy to install.

[0055] The first frame 510 is inserted into the receiving groove 523, that is, the second frame 520 can also protect the first frame 510, avoid the first frame 510 from being bumped and interfered by other components, prevent the air path formed by the first frame 510 and other components from being affected, and further affect the normal operation of the balance surface, thereby improving the stability of the application. In addition, the first frame 510 protects the airflow sensor 300, and the second frame 520 protects the first frame 510, which further ensures the stable working environment of the airflow sensor 300, reduces other influences on the airflow sensor 300, and improves the accuracy and sensitivity of the airflow sensor 300 detection of the application.

[0056] A gap is arranged between the air path plate 511 and the receiving groove 523 to cooperate to form a gas exchange groove 524 in communication with the outside, and the air hole 512 is in communication with the gas exchange groove 524. The air hole 512 is in communication with the first air path 121, the air hole 512 is in communication with the gas exchange groove 524, the gas exchange groove 524 is in communication with the outside atmosphere, and the balance surface is received in the first air path 121. In this way, the balance surface is directly in communication with the outside, so that the balance surface can detect the specific conditions of the outside atmosphere in real time, and the sensitivity of the airflow sensor 300 is ensured.

[0057] In some embodiments, the air passage plate 511 is provided with a ventilation gap 513 at a position away from the ventilation hole 512. The ventilation gap 513 abuts against the side wall of the accommodating groove 523, and is in communication with the ventilation groove 524. The ventilation gap 513 is in communication with the outside of the atomization device. The balance surface is in communication with the outside through the first air passage 121 and the second air passage 122. The second air passage 122 is formed by the cooperation of the ventilation groove 516, the ventilation hole 512, the ventilation groove 524, and the ventilation gap 513 in sequence. First, the ventilation gap 513 ensures that the ventilation groove 524 is in stable and reliable communication with the outside, so that the balance surface can work normally. Second, the balance surface is in communication with the outside through the first air passage 121, the ventilation hole 512, the ventilation groove 524, and the ventilation gap 513, which prolongs the length of the balance air passage 120, and makes the balance air passage 120 meander, so as to effectively avoid impurities floating or contained in the outside air from entering the balance surface along the balance air passage 120 and affecting the normal work of the balance surface, thereby improving the reliability of the present application. Third, the ventilation gap 513 is provided on the air passage plate 511, so that the ventilation groove 524 is in communication with the outside through the ventilation gap 513, which improves the flexibility of the arrangement of the ventilation groove 524, and enables the ventilation groove 524 to be arranged at any position as long as it is in communication with the ventilation gap 513, so that the structural design of the present application is more reasonable.

[0058] It can be understood that the ventilation gap 513 is arranged at the edge of the air passage plate 511, and the ventilation gap 513 and the side wall of the accommodating groove 523 jointly form an air passage in communication with the outside, which can reduce the necessary length of the air passage plate 511. In other words, the ventilation hole 512 and the ventilation gap 513 need to be provided on the air passage plate 511 to enable the first air passage 121 to be in communication with the outside. If the ventilation gap 513 is arranged as a complete channel or a through hole 514, the length of the air passage plate 511 needs to be obviously lengthened. If the length of the air passage plate 511 is not lengthened, the distance between the ventilation hole 512 and the ventilation gap 513 needs to be shortened. In this way, the length of the ventilation groove 524 is also shortened, which affects the protection capability of the second air passage 122 on the balance surface. Therefore, the ventilation gap 513 is arranged at the edge of the air passage plate 511, and the ventilation gap 513 and the side wall of the accommodating groove 523 jointly form an air passage, which enables the ventilation groove 524 to be in normal communication with the outside, ensures the length of the ventilation groove 524, and makes the structure of the air passage plate 511 more reasonable and compact, thereby improving the rationality of the structure of the present application.

[0059] In some embodiments, the communication groove 516 is formed by the first frame body 510 and the electric control element 400 in cooperation, and the communication groove 516 communicates the cavity 515 and the air hole 512. The air hole 512 is formed on the first frame body 510, and the air hole 512 communicates the communication groove 516 and the air exchange groove 524. The air exchange groove 524 is formed by the gap between the first frame body 510 and the second frame body 520, and the air exchange groove 524 communicates the air hole 512 and the air hole gap 513. The air hole gap 513 is formed on the first frame body 510, and the air hole gap 513 abuts on the side wall of the second frame body 520 to form a channel, and the air exchange groove 524 communicates with the outside through the air hole gap 513.

[0060] By cooperation of the first frame body 510, the second frame body 520 and the electric control element 400, the second air path 122 is formed, and the second air path 122 is specifically formed by cooperation of the communication groove 516, the air hole 512, the air exchange groove 524 and the air hole gap 513, which ensures the smoothness of the second air path 122 in sequence, and further ensures the communication between the balance surface and the outside. In addition, by cooperation of the first frame body 510, the second frame body 520 and the electric control element 400 to form the second air path 122, the length and protection ability of the second air path 122 can be ensured, so as to avoid contact between foreign matters in the outside and the balance surface, protect the balance surface, and also ensure the accuracy and sensitivity of the airflow sensor 300.

[0061] In some embodiments, as shown in Figure 3 、 Figure 5 、 Figure 6 The side of the first frame body 510 facing the balance surface is sealingly arranged with the electric control element 400, and a gap is arranged between the balance surface and the electric control element 400 to form the first air path 121. By protecting the airflow sensor 300 by the first frame body 510, the airflow sensor 300 is prevented from being disturbed by other parts in the atomization device of the application, and the airflow sensor 300 is also prevented from being bumped by external objects or other parts during installation. In addition, the cavity 515 is formed on the first frame body 510, and the airflow sensor 300 is installed in the cavity 515. By the cavity 515, the airflow sensor 300 is protected, and at the same time, a relatively stable detection environment is provided for the airflow sensor 300, so as to improve the detection accuracy of the airflow sensor 300.

[0062] The first frame body 510 and the electric control element 400 are sealingly arranged, which can more reliably protect the airflow sensor 300. A gap is arranged between the balance surface of the airflow sensor 300 and the electric control element 400, and the gap forms the first air path 121, so that the balance surface can communicate with the outside through the first air path 121, and the detection environment of the balance surface is further stabilized.

[0063] In some embodiments, as shown in Figure 4 The airflow sensor 300 is electrically connected with the electric control element 400. The atomization assembly 200 further comprises a heating element, and the heating element comprises a heating pin electrically connected with the electric control element 400. The airflow sensor 300 and the heating pin are both electrically connected with the electric control element 400. On the one hand, the atomization device of the present application can respond more quickly, that is, when the airflow sensor 300 detects that the user has a puffing action, an electrical signal is timely sent to the electric control element 400, the electric control element 400 processes the electrical signal and sends a feedback signal to the heating pin, which is transmitted to the heating element through the heating pin, so that the heating element heats and atomizes the atomization substrate in the atomization assembly 200 for the user to use. On the other hand, the airflow sensor 300 and the heating pin share the same electric control element 400, which can make the structure of the present application more compact and the space utilization in the atomization device more reasonable and efficient.

[0064] In some embodiments, as shown in Figure 4 The electric control element 400 comprises a circuit board, and the airflow sensor 300 is electrically connected with the circuit board. The circuit board is provided with a pin connecting portion 410 extending towards the edge of the atomization assembly 200, and the heating pin is electrically connected with the pin connecting portion 410. The airflow sensor 300 is arranged above the circuit board, and the airflow sensor 300 is electrically connected with the circuit board. The pin connecting portion 410 is arranged on the circuit board and extends from the circuit board. Under the premise that the airflow sensor 300 and the heating pin share the same circuit board, the setting position of the heating pin can be expanded, that is, the heating pin can be arranged at any reasonable position, and the pin connecting portion 410 of the circuit board can extend below the heating pin for connecting the heating pin, thereby further improving the reliability and rationality of the present application.

[0065] In some embodiments, as shown in Figure 3 , Figure 5 , Figure 6 The housing 100 further comprises a second frame body 520, and the second frame body 520 is provided with a receiving groove 523, and the first frame body 510 is inserted into the receiving groove 523. A second air passage 122 is formed between the first frame body 510 and the receiving groove 523. The first frame body 510 is inserted into the receiving groove 523 of the second frame body 520, and the receiving groove 523 limits the relative position of the second frame body 520, reduces the installation difficulty of the first frame body 510 and the second frame body 520, and makes the present application easy to install.

[0066] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 11As shown, the balance surface is in communication with the outside through the first air path 121 and the second air path 122; the second air path 122 is formed by the communication groove 516, the air hole 512, the air exchange groove 524 and the air exchange notch 513 in sequence. In this way, the balance surface can be in communication with the outside through the first air path 121, the communication groove 516, the air hole 512, the air exchange groove 524 and the air exchange notch 513 in sequence, so as to ensure that the balance surface can detect the relevant data of the outside atmosphere in real time, and the airflow sensor 300 of the present application remains sensitive.

[0067] In some embodiments, for example, Figures 7 to 10 As shown, the second frame body 520 is provided with the sensing air channel 111, which is in communication with the detection air channel 110. The first frame body 510 is sealingly arranged between the accommodation groove 523 and is provided with the through hole 514 on the side facing the sensing surface, which is in communication with the sensing air channel 111. The sensing surface of the airflow sensor 300 is in communication with the sensing air channel 111 through the through hole 514, and the sensing air channel 111 is in communication with the detection air channel 110. In this way, when the airflow or the air pressure in the detection air channel 110 changes, the sensing surface can detect it in time and compare it with the relevant data detected by the balance surface to determine whether to send a signal to start or stop the atomization device of the present application.

[0068] Specifically, when the user uses the atomization device of the present application, the atomization substrate is drawn outwards through the atomization channel 210, the detection air channel 110 is in communication with the atomization channel 210, and the detection air channel 110 generates airflow, the sensing air channel 111 generates airflow, the sensing surface can detect the change of the airflow in time, thereby sending a signal to control the atomization device of the present application to start and supply the user. Or when the gas flows in the detection air channel 110, the sensing air channel 111 generates negative pressure, the sensing surface can also detect the air pressure related data and compare it with the detection result of the balance surface. As long as there is any difference between the detection results of the balance surface and the sensing surface, the airflow sensor 300 sends a signal to the atomization device to control the atomization device to start.

[0069] In some embodiments, for example, Figures 7 to 10As shown, the end face of the accommodating groove 523 close to the sensing surface is provided with a protrusion 521, which is sealed and abuts on the shell 100. An extension passage is formed in the protrusion 521 and communicates with the through hole 514, and the extension passage is provided with a protrusion notch 522 facing the sensing air channel 111, and the extension passage communicates with the sensing air channel 111 through the protrusion notch 522. The protrusion 521 is sealed and abuts on the shell 100, the extension passage is arranged in the protrusion 521, and the extension passage is provided with the protrusion notch 522, that is, the sensing surface can communicate with the sensing air channel 111 through the through hole 514, the extension passage and the protrusion notch 522, and the sensing surface can detect the airflow related data in the sensing air channel 111; the sensing air channel 111 communicates with the detection air channel 110, and the detection air channel 110 communicates with the atomization channel 210, so that when the airflow related data in the atomization channel 210 or the detection air channel 110 changes, the sensing surface can detect in time and feedback, so that the application has rapid and sensitive response, and the use experience of the user is improved.

[0070] It should be noted that the protrusion notch 522 is arranged on the extension passage and faces the sensing air channel 111, so that the sensing surface only communicates with the sensing air channel 111, and the sensing surface does not communicate with other cavities in the atomization device of the application, thereby reducing the detection range of the sensing surface and improving the detection accuracy and sensitivity of the sensing surface.

[0071] The sensing surface and the balance surface of the airflow sensor 300 can be arranged at any suitable position of the airflow sensor 300, as long as the sensing surface is located in the detection air channel 110 and the balance surface is located in the balance air channel 120. For example, as shown in Figure 9 , Figure 10 As shown, the sensing surface is arranged on one side of the airflow sensor 300 facing the protrusion notch 522, and the balance surface is arranged on one side of the airflow sensor 300 facing the first air channel; that is, the sensing surface is arranged on the upper side of the airflow sensor 300, and the balance surface is arranged on the lower side of the airflow sensor 300.

[0072] In some embodiments, for example, as shown in Figure 1 , Figure 2 As shown, the shell 100 of the application further comprises an oil storage assembly and a power supply assembly, the oil storage assembly can supply the atomization matrix to the atomization assembly 200, and the power supply assembly can supply power to the electronic control element 400 and the atomization assembly 200. When the application is used, the user sucks the atomization matrix outward, the airflow sensor 300 detects that the airflow related data changes, sends a signal to the electronic control element 400, the electronic control element 400 is started, controls the heating element in the atomization assembly 200, heats the atomization matrix supplied by the oil storage assembly, atomizes it, and supplies it to the user.

[0073] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
