[0002] At present, there are two main different ways for users to inhale atomized gas. One of the inhalation methods is the mouth inhalation method, in which the user only inhales the atomized gas into the oral cavity. The other inhalation method is the lung inhalation method, in which the user inhales the atomized gas into the lungs. Since the lung inhalation site is deeper than the mouth inhalation site, the flow rate of the atomized gas inhaled by the user during mouth inhalation is smaller than the flow rate of the atomized gas inhaled by the user during lung inhalation. However, the current electronic atomizer cannot provide users with different atomized gas flow rates to suit different inhalation methods of users. Summary of the invention

[0039] Example 1

[0040] like Figure 1 As shown, the embodiment of the present invention discloses an electronic atomizer, which includes an atomizing device 200 and a power supply device 100. The atomizing device 200 is used to atomize atomizable liquid, such as Figure 4 As shown, the atomizing device 200 is provided with an air flow channel 230, an air inlet 210 and an air outlet 220, one end of the air flow channel 230 is connected to the air inlet 210, and the other end opposite to the air outlet 220 is connected;

[0041] The aforementioned atomizable liquid is in liquid form at room temperature and can be stored in the atomizing device 200. Such liquids will atomize when heated to a certain temperature. The atomizing device 200 is provided with an atomizing core that can atomize the atomizable liquid by heating. The user inhales at the air outlet 220 of the atomizing device 200. Since the air flow channel 230 is connected to the air outlet 220, a negative pressure is generated in the air flow channel 230. Since the air flow channel 230 is connected to the air inlet 210, the air outside the atomizing device 200 enters the air flow channel 230 from the air inlet 210 under the action of the negative pressure in the flow channel. The gas entering the air flow channel 230 is mixed with the atomized atomizable liquid and then flows out from the air outlet 220 and is inhaled into the body by the user.

[0042] like Figure 2 and Figure 3 As shown, the power supply device 100 is used to provide electric energy to the atomizing device 200, the power supply device 100 and the atomizing device 200 are detachably connected at a first relative position or a second relative position, and a shielding portion 110 is further provided on the power supply device 100;

[0043] Since the atomizable liquid is atomized by heating, the power supply device 100 is provided in this embodiment to provide power to the atomizing device 200. The atomizing device 200 can heat the atomizable liquid by a heating device so that the atomized liquid is mixed with the gas entering the air flow channel 230 after being atomized.

[0044] In the present embodiment, the power supply device 100 can form a detachable connection with the atomization device 200 at any one of two different relative positions, namely the aforementioned first relative position and the second relative position. The aforementioned relative position refers to the relative position relationship between the power supply device 100 and the atomization device 200, without considering the position relationship with other objects. For example, the power supply device 100 is on one side or the other side of the atomization device 200 along its length direction, or the power supply device 100 is on one side or the other side of the atomization device 200 along its width direction, or the power supply device 100 is at a certain angular position of the atomization device 200, or the power supply device 100 is at a certain axial position of the atomization device 200, etc. In this article, the length direction of the power supply device 100 is Figure 2 The x direction of the power supply device 100 is Figure 2 In the y direction, the thickness direction of the power supply device 100 is a direction perpendicular to both the x direction and the y direction, and the length direction, width direction and thickness direction of the atomization device 200 and the entire electronic atomizer are consistent with the power supply device 100.

[0045] like Figure 3As shown, when the power supply device 100 and the atomization device 200 are connected at the first relative position, the shielding portion 110 is located at a position that shields at least a portion of the flow cross section of the air flow channel 230; Figure 2 As shown, when the power supply device 100 and the atomization device 200 are connected at the second relative position, the shielding portion 110 is located at a position where the cross section of the air flow channel 230 is not shielded.

[0046] The above two relative positions correspond to two ways of inhaling gas by the user. When the user adopts the mouth-inhalation inhalation method, the user can connect the power supply device 100 and the atomization device 200 at the first relative position. At this time, the shielding portion 110 on the power supply device 100 blocks a part of the airflow channel 230, thereby reducing the cross-sectional area of ​​the gas that can flow in the airflow channel 230. At this time, when the user inhales at the air outlet 220, the flow rate of the inhalable gas is correspondingly reduced.

[0047] When the user adopts the lung inhalation mode, the user can connect the power supply device 100 and the atomization device 200 at the second relative position. At this time, the air flow channel 230 is not blocked by the shielding portion 110 on the power supply device 100, and the area of ​​the flow cross section of the air flow channel 230 is the largest. At this time, when the user inhales at the air outlet 220, the flow rate of the inhalable gas is also the largest.

[0048] Since the connection modes of the power supply device 100 and the atomization device 200 at two relative positions are both detachable, when the user needs to switch from one inhalation mode to another inhalation mode, he only needs to remove the atomization device 200 from the current connected relative position and then connect it to the power supply device 100 at another relative position.

[0049] Example 2

[0050] like Figure 3 and Figure 4 As shown, in the present embodiment, a plug hole 231 is formed at one end of the air flow channel 230 facing the air inlet 210, and when the power supply device 100 and the atomization device 200 are connected at a first relative position, the shielding portion 110 is located in the plug hole 231; when the power supply device 100 and the atomization device 200 are connected at a second relative position, the shielding portion 110 is located outside the plug hole 231.

[0051] In this embodiment, one end of the air inlet of the airflow channel 230 is designed in the form of a plug hole 231, and the tail end of the plug hole 231 is the air inlet 210. The shielding part 110 of the power supply device 100 can be inserted into the aforementioned plug hole 231. When the user adopts the mouth-inhalation method, the power supply device 100 is connected to the atomization device 200 at the first relative position, and the plug hole 231 can be used as a plug-in positioning structure and a connection structure. The user can insert the shielding part 110 into the aforementioned plug hole 231, so that the power supply device 100 and the atomization device 200 form a connection with accurate position and high reliability. At the same time, since the shielding part 110 is a part of the airflow channel 230, after the shielding part 110 is inserted into the aforementioned plug hole 231, at least a part of the plug hole 231 can be blocked, thereby reducing the flow cross-sectional area of ​​other parts in the airflow channel 230. The size of the plug hole 231 can be set according to the inhaled gas flow rate when the user inhales by lung. The size of the shielding portion 110 can be designed according to the flow rate of the inhaled gas when the user inhales through the mouth.

[0052] like Figure 4 As shown, as a further improvement, in the present embodiment, a slot 232 is further provided on the atomization device 200, and the slot 232 and the air flow channel 230 are not communicated with each other, and the slot 232 and the plug hole 231 are located at the same end of the atomization device 200, and when the power supply device 100 and the atomization device 200 are connected at the second relative position, the shielding portion 110 is located in the plug slot.

[0053] In this embodiment, a slot 232 and a plug hole 231 can be provided at the first end where the atomizing device 200 is connected to the power supply device 100. When the user adopts the lung inhalation method, the power supply device 100 is connected to the atomizing device 200 at a first relative position, the shielding portion 110 is located in the plug hole 231, and blocks a portion of the airflow channel 230. When the user adopts the mouth inhalation method, the power supply device 100 is connected to the atomizing device 200 at a second relative position, the shielding portion 110 is located in the slot 232, and the airflow channel 230 is not blocked. At this time, the plug slot can be used as a limiting structure and a connecting structure, and the power supply device 100 and the atomizing device 200 can form a connection with accurate position and high reliability through the shielding portion 110 and the slot 232.

[0054] In addition, in this embodiment, when the power supply device 100 is connected to the atomizing device 200 at the first relative position, an annular airflow channel 230 is formed between the shielding portion 110 and the plug hole 231. When the user adopts the mouth-inhalation inhalation method, the shielding portion 110 is inserted into the plug hole 231. At this time, the cross-section of the airflow channel 230 for gas circulation is annular, so that the gas can flow around the shielding portion 110, so that the airflow speed in each direction of the airflow channel 230 is consistent, thereby improving the stability of the flow of the airflow. The shielding portion 110 can be set to a cylindrical shape, and the plug hole 231 can be set to a circular hole slightly larger than the diameter of the shielding portion 110. When plugged in, the center of rotation of the shielding portion 110 coincides with the center of rotation of the plug hole 231, thereby forming a centrally symmetrical circular cross section between the shielding portion 110 and the plug hole 231.

[0055] like Fig.15 As shown, in the present embodiment, a receiving chamber 120 is provided at one end of the power supply device 100 facing the atomization device 200, and a second connecting portion whose shape matches the shape of the inner wall of the receiving chamber 120 is provided at one end of the atomization device 200 facing the power supply device 100, the opening of the slot 232 and the opening of the plug hole 231 are located on a side of the second connecting portion facing the power supply device 100, the second connecting portion is plugged into the receiving chamber 120, the shape of the inner wall of the receiving chamber 120 is symmetrical about a reference plane, the positions of the slot 232 and the plug hole 231 are symmetrical about the reference plane, and the reference plane is a plane parallel to the length direction of the power supply device 100.

[0056] Since the end of the atomizer 200 for connection can enter the accommodating chamber 120 of the power supply device 100 after plugging, the connected part will not be exposed, and from the outside, the integrity of the atomizer 200 and the power supply device 100 is stronger. At the same time, the connection structure of the second connection part can also be protected by the shell of the power supply device 100. In addition, in this embodiment, the shape of the inner wall of the accommodating chamber 120, the shape of one end of the atomizer 200 connected, the slot 232 and the position of the plug hole 231 are set to be symmetrical about the same reference plane. In this way, when the user adopts the mouth-inhalation method, the shielding part 110 can be inserted into the aforementioned plug hole 231, and the power supply device 100 is connected to the atomizer 200 at the first relative position. When the user switches the mouth-inhalation method to the lung-inhalation method, the atomizer 200 can be removed from the power supply device 100, and then the atomizer 200 is rotated 180 degrees, and the shielding part 110 is inserted into the plug hole 231, and the power supply device 100 is connected to the atomizer 200 at the second relative position. Since the shape of the inner wall of the accommodating chamber 120 and the shape of the end to which the atomizing device 200 is connected are symmetrical about the reference plane, the atomizing device 200 and the power supply device 100 can form a reliable connection at the two relative positions, and the two plug-in methods will not change the appearance of the electronic atomizer. The structure of this embodiment allows the user to switch between the two inhalation methods by simply rotating the atomizing device 200 180 degrees relative to the power supply device 100, which is simple and convenient to operate.

[0057] In this embodiment, the atomization device 200 further includes a plurality of electrode contacts arranged axially symmetrically, the slot 232 and the plug hole 231 are arranged axially symmetrically, and the symmetry axis of the slot 232 and the plug hole 231 is the same as the symmetry axis of the plurality of electrode contacts.

[0058] When an electrical connection is required between the atomizing device 200 and the power supply device 100, electrodes are often provided on the atomizing device 200 and the power supply device 100, wherein the portion where the electrode on the atomizing device 200 contacts the electrode on the power supply is referred to herein as an electrode contact. There are often multiple electrodes on the atomizing device 200, and each electrode corresponds to an electrode contact. In this embodiment, the electrode contacts on the atomizing device 200 are in the form of axisymmetric steps, that is, the projection of the electrode contacts on the atomizing device 200 on a reference plane perpendicular to the length direction of the electronic atomizer is symmetrical about a given symmetry axis on the reference plane.

[0059] With the above structure, when the first relative position and the second relative position of the atomizing device 200 and the power supply device 100 differ by 180 degrees, for the electrode contacts, the positions and shapes of the electrode contacts on the atomizing device 200 are the same under the above two different position connection modes. In this way, whether the atomizing device 200 and the power supply device 100 are connected at the first relative position or at the second relative position, the electrode contacts on the atomizing device 200 can form a reliable electrical connection with the power supply device 100. As a preferred embodiment, the electrode contacts on the power supply device 100 can also be set to be axially symmetrical, and the axis of symmetry is the same as the axis of symmetry of the electrode contacts on the atomizing device 200.

[0060] like Figure 3 As shown, the plurality of axially symmetrical electrode contacts include a first electrode contact 251 and a second electrode contact 252 symmetrical about a reference plane; when the power supply device 100 is connected to the atomization device 200 at a first relative position, the first electrode contact 251 is electrically connected to the positive electrode of the power supply device 100, and the second contact is electrically connected to the negative electrode of the power supply device 100; when the power supply device 100 is connected to the atomization device 200 at a second relative position, the first electrode contact 251 is electrically connected to the negative electrode of the power supply device 100, and the second contact is electrically connected to the positive electrode of the power supply device 100.

[0061] Since the power supply device 100 has a positive output terminal and a negative output terminal, the electrode contacts of the atomizer device 200 in this embodiment are also provided with two electrode contacts symmetrical about the reference plane. Whether the atomizer device 200 and the power supply device 100 are connected at the first relative position or the second relative position, the connection with the positive and negative electrodes of the power supply device 100 can be achieved. Moreover, the connection of the positive and negative electrodes of the power supply corresponding to the two relative positions is just opposite, and the control circuit in the power supply device 100 can also quickly identify the relative position relationship between the atomizer device 200 and the power supply device 100 when they are connected according to the polarity of the power connection.

[0062] In this embodiment, the plurality of axially symmetrically arranged electrode contacts further include a third electrode contact 253 , and the third electrode contact 253 is electrically connected to a signal input and / or output terminal of the power supply device 100 .

[0063] The electronic atomizer of this embodiment can use the third electrode contact 253 to enable the power supply device 100 and the atomization device 200 to transmit information or data to each other through electrical signals. The third electrode contact 253 can be symmetrical about the aforementioned axis. In this embodiment, the power supply device 100 is provided with an electrode for transmitting signals.

[0064] In addition to the aforementioned plane-symmetrical structural form, this embodiment also provides a centrally symmetrical structural form. The atomizing device 200 also includes a plurality of centrally symmetrically arranged electrode contacts, the slot 232 and the plug hole 231 are centrally symmetrically arranged, and the symmetry axis of the slot 232 and the plug hole 231 is the same as the symmetry axis of the plurality of electrode contacts. The electrode contacts, slots 232 and plug holes in this embodiment are centrally symmetrical about the same symmetry axis. In this way, when the user rotates the atomizing device 200 relative to the power supply device 100 along the centrally symmetrical symmetry axis by a certain angle, the conversion between the first relative position and the second relative position can be achieved, and the atomizing device 200 and the power supply device 100 can achieve stable and reliable structural and electrical connections in both relative positions.

[0065] Example 3

[0066] The power supply device 100 of this embodiment includes a housing, a battery, a first bracket 150 and at least one electrode. The housing is provided with a receiving cavity. The battery is located in the receiving cavity. Figure 8 and Fig.13 As shown, the first bracket 150 is provided with a connecting portion 151 at one end thereof along the length direction of the power supply device 100 toward the atomizing device 200, and the connecting portion 151 is provided with a mounting hole 154 penetrating the connecting portion 151 along the length direction of the power supply device 100; the electrode is electrically connected to the battery, as shown in FIG. Figure 8 As shown, the electrode includes a first end and a second end that are oppositely disposed, the first end passes through the mounting hole 154 , and the second end is located in the mounting hole 154 .

[0067] In order to facilitate the fixing and installation of the battery, the power supply device uses the first bracket 150 to install and fix the battery. In order to facilitate the installation and removal of the battery, in this embodiment, the first bracket 150 is a semi-enclosed structure, such as a "C"-shaped structure. The semi-enclosed structure can be used to locate and install the battery from three sides, and the side that is not enclosed can reserve the operating space required for installing and removing the battery.

[0068] In order to make the electrode on the power supply device 100 reliably contact the electrode contact on the atomizer 200, the present embodiment installs and positions the electrode on the power supply device 100 through the mounting hole 154 provided on the connecting portion 151 of the first bracket 150. The mounting hole 154 and the electrode are both provided along the length direction of the power supply device 100, with one end facing the battery in the accommodating cavity and the other end facing the atomizer 200. The mounting hole 154 is a through hole that penetrates the connecting portion 151 of the first bracket 150. The electrode is inserted into the mounting hole 154, and the first end of the electrode for contacting the electrode contact of the atomizer 200 emerges from the mounting hole 154, so that the power supply device 100 and the atomizer 200 can be fully contacted with the electrode contact on the atomizer 200 when connected. The other end of the electrode for forming an electrical connection with the battery is not exposed outside the mounting hole 154, but is hidden in the mounting hole 154. In this way, the electrode can be protected by the mounting hole 154, and will not collide with other components in the accommodating cavity and cause damage. In addition, electrical connection materials such as solder may be filled in the mounting hole 154, and the second end of the electrode and the battery may be electrically connected by the electrical connection material. The battery may be electrically connected to the second end of the electrode by the electrical connection material, or the battery may be electrically connected to the circuit board 160, and the circuit board 160 may be electrically connected to the second end of the electrode by the electrical connection material.

[0069] In this embodiment, a limiting structure is provided on the inner wall of the mounting hole 154, and the limiting structure is used to limit the axial position of the electrode.

[0070] The limiting structure includes a limiting step 155, such as Figure 6 As shown, a positioning ring 1611 is provided on the side wall of the electrode, and the positioning ring 1611 abuts against the limiting step 155. Figure 7 As shown, during assembly, the electrode is inserted into the mounting hole 154 from the mounting hole 154 toward one end of the atomizing device 200, and is further inserted along the axial direction of the mounting hole 154 toward the battery direction until the positioning ring 1611 on the electrode abuts against the step in the mounting hole 154, and the second end of the electrode is just located at a pre-set axial position. The above structure is convenient for installation and accurate for positioning, and can effectively prevent the second end of the electrode from being damaged.

[0071] In this embodiment, the power supply device 100 includes a first electrode 161, a second electrode 162 and a third electrode 163, wherein the first electrode is used to be electrically connected to the positive electrode of the battery, the second electrode 162 is used to be electrically connected to the negative electrode of the battery, and the third electrode 163 is used to transmit signals.

[0072] In this embodiment, in addition to the first electrode 161 and the second electrode 162 connected to the positive and negative electrodes of the battery, a third electrode 163 is also provided. In this way, the current signal or voltage signal on the third electrode 163 can be used to communicate with other electronic devices or equipment.

[0073] As a preferred embodiment, in this embodiment, the first electrode 161 and the second electrode 162 are symmetrical about a reference plane, and the reference plane is a plane parallel to the length direction of the power supply device 100. The aforementioned structure is used in the case where the atomization device 200 and the power supply device 100 can be connected in both forward and reverse plugging modes. The first electrode and the second electrode 162 are symmetrical about the reference plane, so the atomization device 200 can be in contact with the first electrode and the second electrode 162 when connected to the power supply device 100 at two positions 180 degrees apart without changing the original electrode contact position and size.

[0074] In this embodiment, the first electrode, the second electrode 162 and the third electrode 163 are located at different vertices of the same triangle. The first electrode, the second electrode 162 and the third electrode 163 are arranged in the above manner, so that the third electrode 163 used for transmitting signals is staggered with the first electrode and the second electrode 162 by a certain distance, thereby avoiding interference of the first electrode and the second electrode 162 when the third electrode 163 is in a straight line with the first electrode and the second electrode 162.

[0075] When the first electrode and the second electrode 162 are symmetrical about the reference plane, the first electrode contact 251 and the second electrode contact 252 are also symmetrical about the reference plane. When the first electrode, the second electrode 162 and the third electrode 163 are located at different vertices of the same triangle, the first electrode contact 251, the second electrode contact 252 and the third electrode contact 253 are also located at different vertices of the same triangle. The third electrode contact 253 can be set to a rectangle, and the side length of the rectangle is greater than or equal to so that the third electrode contact 253 can reliably contact the electrode when the atomization device 200 and the power supply device 100 are connected in two different relative positions.

[0076] Example 4

[0077] In this embodiment, if Fig.10As shown, the atomizing device 200 includes: a circuit board 160, a display screen 170, a battery (not shown in the figure), and a second bracket 140. The display screen 170 is mounted on the circuit board 160; a receiving cavity is provided, the display screen 170 is located in the receiving cavity, and a first window for viewing the display screen 170 is provided at a position corresponding to the display screen 170; the battery is located in the receiving cavity; the second bracket 140 is covered outside the display screen 170, and a second window 144 is provided at a position corresponding to the display screen 170 on the second bracket 140.

[0078] The battery is used to store electrical energy, and a control circuit can be provided on the circuit board 160, through which the power supply mode of the battery can be controlled. The display screen 170 is electrically connected to the control circuit. The control circuit can control the display screen 170 to display some information related to the electronic atomizer. The method for the control circuit to control the display of the display screen 170 can adopt the existing technology, which will not be elaborated here. The circuit board 160, the display screen 170, the battery, the second bracket 140 and other parts can be arranged in the accommodating cavity to protect these parts. In order to facilitate the user to view the content displayed on the display screen 170, the first window 131 is provided on the present embodiment, and the window connects the inside and the outside. The light emitted from the display screen 170 can be emitted to the outside of the power supply device 100 through the first window, so that the user can see the content displayed on the display screen 170 from the outside of the power supply device 100. Among the aforementioned components, the display screen 170 is the most susceptible to damage. As Figure 2 and Figure 3 As shown, in this embodiment, a second bracket 140 is provided to protect the display screen 170. The second bracket 140 covers the side of the display screen 170 facing away from the circuit board 160 to prevent external force from directly acting on the display screen 170 and causing damage to the display screen 170. Fig.11 and Fig.12 As shown, in this embodiment, a second window 144 is further provided on the second bracket 140, so that the light emitted from the display screen 170 can be emitted to the outside of the power supply device 100 through the second window 144 and the first window. In this way, the user can not only watch the content displayed on the display, but also use the second bracket 140 to protect the display screen 170. When the power supply device 100 is subjected to an external force, the second bracket 140 covering the outside of the display screen 170 can prevent the force from being directly transmitted to the display screen 170, thereby effectively protecting the display screen 170.

[0079] like Fig.11As shown, in this embodiment, a protruding structure 153 is provided on the second bracket 140. The protruding structure 153 is located on a side of the first bracket 150 close to the first window along the thickness direction of the power supply device 100. The protruding structure 153 supports the first bracket 150 along the thickness direction of the power supply device 100.

[0080] like Fig.11 As shown, in this embodiment, the second bracket 140 includes a bearing portion 141, a first supporting portion 142 and a second supporting portion 143, the first supporting portion 142 and the second supporting portion 143 are located at two ends of the bearing portion along the width direction of the power supply device 100, and the second window 144 is located on the bearing portion 141;

[0081] One end of the first supporting portion 142 is connected to the circuit board 160 , and the other end thereof supports the bearing portion. One end of the second supporting portion 143 is connected to the circuit board 160 , and the other end thereof supports the bearing portion.

[0082] The second bracket 140 is connected to the circuit board 160 through the first support portion 142 and the second support portion 143 at both ends. The first support portion 142 and the second support portion 143 can be formed by extending a distance from the position connected to the circuit board 160 in the direction away from the display screen 170, so as to support the bearing portion at a certain height. The bearing portion is located between the display screen 170 and the bearing portion. When subjected to external force, the bearing portion first bears a part of the external load, and a part of the load is also borne by the first support portion 142 and the second support portion 143. In this embodiment, the second bracket 140 and the circuit board 160 can together form a protective structure, and the display screen 170 is just located in the protective structure and protected.

[0083] In this embodiment, a protruding structure 153 is provided on the second bracket 140 . The protruding structure 153 is located on a side of the first bracket 150 close to the first window along the thickness direction of the power supply device 100 . The protruding structure 153 supports the first bracket 150 along the thickness direction of the power supply device 100 .

[0084] The protruding structure 153 can be formed by extending the bearing portion of the second bracket 140 toward the near side. When the first bracket 150 moves relative to the second bracket 140 along the thickness direction of the power supply device 100, the protruding structure 153 provided on the second bracket 140 can hold the first bracket 150, thereby preventing the first bracket 150 from moving relative to the second bracket 140 along the thickness direction of the power supply device 100.

[0085] As a preferred embodiment, the protrusion structure 153 includes a plurality of protrusions arranged at intervals along the length direction of the power supply device 100. The use of the protrusions arranged at intervals can reduce the weight of the second bracket 140, and an assembly operation space can be reserved between adjacent protrusions. At least a portion of the first bracket is located on the side of the display screen facing the housing, and a third window 156 is provided on the first bracket at a position corresponding to the display screen. Preferably, the third window 156 is located between the bearing portion and the first window.

[0086] Example 5

[0087] like Fig.13 As shown, in this embodiment, the power supply device 100 is used to provide power to the atomizing device, and the power supply device 100 includes a microphone 180, an air pressure detection device, a connecting portion 151 and a blocking structure 1514; a chamber is provided inside the microphone 180; the air pressure detection device is used to detect the air pressure in the chamber;

[0088] The chamber is connected to the air outlet 220 of the atomizer. When the user inhales at the atomizer outlet 220 and the suction force is appropriate, a negative pressure will be formed in the chamber inside the microphone 180. And a sufficient negative pressure value can be reached. If the user's suction force is not enough or the flue is not smooth, the amount of smoke flowing to the smoking port is insufficient, and negative pressure cannot be formed in the chamber or the negative pressure value is low. The preset threshold value of the negative pressure in the chamber can be set according to the requirements of the suction force. The power supply device 100 can use the air pressure detection device to detect the negative pressure value in the chamber. When the negative pressure value reaches the preset threshold value, it indicates that the user has successfully inhaled. At this time, the air pressure detection device generates a trigger signal and sends the trigger signal to the controller for processing. The controller receives the trigger signal and controls the heating device to start working to atomize the liquid in the atomizer.

[0089] The connecting portion 151 is located at one end of the power supply device 100 along its length direction. The connecting portion 151 is provided with a first airflow port 1511 on one side facing the atomizer device. The first airflow port 1511 is connected to the chamber. The airflow flows into or flows out of the chamber of the microphone 180 through the first airflow port 1511. When the user inhales at the atomizer outlet 220, the gas in the chamber of the microphone 180 flows out of the chamber from the first airflow port 1511, so that a negative pressure is formed in the chamber of the microphone 180. The first airflow port 1511 and the chamber can be connected by a channel for airflow.

[0090] like Fig.14As shown, the barrier structure 1514 is used to isolate the first air flow outlet 1511 from the external environment outside the preset range. The preset range can be set according to actual needs. For example, the preset range can be the area near the first air flow outlet 1511. In this embodiment, the barrier structure 1514 blocks the environment outside the preset range to prevent the gas in these areas from flowing with the gas near the first air flow outlet 1511, thereby interfering with the internal chamber of the microphone 180 connected to the first air flow outlet 1511, so that the chamber inside the microphone 180 can quickly form a stable negative pressure value when the user puffs normally. In this way, when the user is puffing, the air pressure detection device located in the microphone 180 can quickly and accurately detect the negative pressure value that meets the trigger condition, so that the controller can timely and accurately control the heater to atomize the liquid.

[0091] In this embodiment, the barrier structure 1514 is formed by extending from the connection portion 151 toward the direction close to the atomizing device. When the power supply device 100 and the atomizing device are connected, the barrier structure 1514 can abut against the atomizing device, so that the barrier structure 1514 and the end of the atomizing device form a relatively closed space, and the first airflow outlet is located in the space, so that when the user inhales, it is easier to form a stable negative pressure in the chamber inside the microphone 180.

[0092] In this embodiment, the barrier structure 1514 includes a first rib 1541 and a second rib 1542, and the first air flow opening 1511 is located between the first rib 1541 and the second rib 1542. In this embodiment, the first air flow opening 1511 is protected by the first rib 1541 and the second rib 1542 on both sides of the first air flow opening 1511, and the first air flow opening 1511 is separated from the external air flow. In addition, the rib structure is simple and can be integrally formed on the surface of the connecting portion 151 facing the atomizing device.

[0093] In addition, in this embodiment, a first boss 1543 and a second boss 1544 are provided on the connecting portion 151, the first boss 1543 is provided with a first mounting hole for mounting the first magnetic component, the second boss 1544 is provided with a second mounting hole for mounting the second magnetic component, and one end of the first rib 1541 is connected to the first boss 1543.

[0094] In this embodiment, the first magnetic member and the second magnetic member are respectively installed in the first mounting hole and the second mounting hole of the first boss 1543 and the second boss 1544, so that the power supply device 100 can use the magnetism of the magnetic member to form a detachable connection with the atomization device conveniently and quickly. At the same time, in this embodiment, the raised part of the first boss 1543 cooperates with the first rib 1541 to effectively block the airflow outside the preset range of the first air flow port 1511.

[0095] When the power supply device is connected to the atomization device at a first relative position, the air inlet and the first air flow outlet are separated by the blocking structure 1514; when the power supply device is connected to the atomization device at a second relative position, the air inlet and the first air flow outlet are separated by the blocking structure.

[0096] Regardless of the plug-in mode of mouth suction or lung suction, the air inlet and the first air flow outlet are separated by the shielding portion, so that the airflow near the air inlet will not interfere with the first air flow outlet, thereby making the airflow near the first air flow outlet more stable.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
