In case of conflict, various features of the embodiments and examples of the present invention may be combined with each other and are within the scope of the present invention.

Example 1

As shown in fig. 1 and fig. 2, an embodiment of the present invention discloses a power supply device 100, where the power supply device 100 is used for providing electric energy for an atomization device, and the power supply device 100 includes a microphone 120, an air pressure detection device, a first end 130, and a blocking structure 140; a cavity 121 is arranged inside the microphone 120; the air pressure detection device is used for detecting the air pressure in the chamber 121;

as shown in fig. 3, the chamber 121 is connected to the atomizing outlet 220 of the atomizing device, and when the user sucks on the atomizing outlet 220 and the suction force is appropriate, a negative pressure is formed in the chamber 121 inside the microphone 120. And a sufficient negative pressure value can be achieved. If the suction force of the user is insufficient or the flue is not smooth, the amount of the smoke flowing to the smoke suction port is insufficient, negative pressure cannot be formed in the cavity 121 or the negative pressure value is low. Wherein the preset threshold value of the negative pressure of the chamber 121 can be set according to the requirement of the suction force. The power supply device 100 may utilize an air pressure detection device to detect a negative pressure value in the chamber 121, and when the negative pressure value reaches a preset threshold value, the negative pressure detection device indicates that the user successfully sucks, and then the air pressure detection device generates a trigger signal and sends the trigger signal to a controller for processing, and the controller receives the trigger signal to control the heating device to start working so as to atomize the liquid in the atomizing device.

The first end portion 130 is located at one end of the power supply device 100 along the length direction thereof, a first airflow port 131 is arranged on one surface of the first end portion 130 facing the atomization device, and the first airflow port 131 is communicated with the chamber 121; the airflow flows into or out of the cavity 121 of the microphone 120 through the aforementioned first airflow port 131. As shown in fig. 3 and 7, when a user sucks on the nebulizer outlet 220, the air in the chamber 121 of the microphone 120 flows out of the chamber 121 from the first airflow port 131, so that the chamber 121 of the microphone 120 is formed with a negative pressure. Wherein the first airflow port 131 and the chamber 121 can be communicated by a channel for flowing the airflow.

The blocking structure 140 is used for blocking the airflow near the first airflow port 131 within a preset range. The preset range can be set according to actual requirements, and the air flow near the first air flow port 131 is blocked by the blocking structure 140 in the embodiment, so that the air near the first air flow port 131 is prevented from flowing outwards, interference is generated on the cavity 121 inside the microphone 120 communicated with the first air flow port 131, and the cavity 121 inside the microphone 120 can quickly form a stable negative pressure value when a user sucks the microphone normally. Thus, when a user sucks, the air pressure detection device in the microphone 120 can quickly and accurately detect the negative pressure value meeting the trigger condition, so that the controller can timely and accurately control the heater to work to atomize the liquid.

In the present embodiment, the blocking structure 140 is formed to extend from the first end 130 toward the direction close to the atomizing device. When the power supply device 100 and the atomizing device are connected, the blocking structure 140 can abut against the atomizing device, so that the blocking structure 140 and the end of the atomizing device form a relatively closed space, and the first airflow outlet is located in the space, so that a stable negative pressure can be more easily formed in the chamber 121 inside the microphone 120 when a user sucks.

In order to further improve the detection sensitivity of the microphone 120, the blocking structure 140 extends from the first end 130 to a position closer to the atomizing device than the first airflow port 131 in the length direction of the power supply device 100. By adopting the above manner, the first airflow port 131 can be buried in the blocking structure 140, so that the influence of the external environment on the first airflow port 131 is further reduced.

As shown in fig. 2, in the present embodiment, the blocking structure 140 includes a first rib 141 and a second rib 142, and the first airflow port 131 is located between the first rib 141 and the second rib 142. In this embodiment, the first airflow port 131 is protected at both sides of the first airflow port 131 by the first ribs 141 and the second ribs 142, and the airflow near the first airflow port 131 is sealed. And the ribs are simple in structure and can be integrally formed on the surface of the first end 130 facing the atomization device.

In addition, in this embodiment, the first end portion 130 is provided with a first boss 151 and a second boss 152, the first boss 151 is provided with a first mounting hole for mounting a first magnetic member, the second boss 152 is provided with a second mounting hole for mounting a second magnetic member, and one end of the first rib 141 is connected to the first boss 151.

In this embodiment, the first magnetic member and the second magnetic member are respectively installed in the first installation hole and the second installation hole of the first boss 151 and the second boss 152, so that the power supply device 100 can be detachably connected to the atomizing device conveniently and quickly by using the magnetism of the magnetic members. Meanwhile, the embodiment utilizes the convex part of the first boss 151 to cooperate with the first ribs 141 to form an effective block for the air flow outside the preset range of the first air flow port 131.

In this embodiment, the first ribs 141 and the second ribs 142 are arc-shaped ribs. The use of the arc-shaped ribs is more advantageous for stabilizing the air flow in the vicinity of the first air flow port 131 between the first ribs 141 and the second ribs 142.

Example 2

As shown in fig. 4, the present embodiment provides an electronic atomizer including an atomizing device and the power supply device described in embodiment 1. Wherein the atomizing device 200 is used for atomizing an atomizable liquid,

the atomizing device 200 is provided with an air flow channel 230, an air inlet 210 and an atomizing air outlet 220, wherein one end of the air flow channel 230 is communicated with the air inlet 210, and the other opposite end is communicated with the atomizing air outlet 220;

when a user inhales at the atomizing air outlet 220 of the atomizing device 200, a negative pressure is generated in the air flow path 230 because the air flow path 230 communicates with the atomizing air outlet 220. Since the air flow channel 230 communicates with the air inlet 210, air outside the atomizer 200 enters the air flow channel 230 from the air inlet 210 by the negative pressure in the air flow channel. The gas entering the gas flow path 230 mixes with the atomized nebulizable liquid and exits through the nebulizing gas outlet 220 and is inhaled by the user.

The power supply device 100 and the atomization device 200 are detachably connected at a first relative position or a second relative position, and the power supply device 100 is further provided with a shielding part 110;

in this embodiment, the power supply device 100 can be detachably connected to the atomizing device 200 at any one of two different relative positions, namely, the first relative position and the second relative position. The foregoing relative positions refer to the relative positional relationship between the power supply device 100 and the atomizing device 200, regardless of the positional relationship with other objects. For example, the power supply device 100 is located on one side or the other side of the atomizer 200 along the length direction thereof, or the power supply device 100 is located on one side or the other side of the atomizer 200 along the width direction thereof, for example, the power supply device 100 is located at a certain angular position of the atomizer 200, for example, the power supply device 100 is located at a certain axial position of the atomizer 200, and the like. Herein, the length direction of the power supply device 100 is the x direction in fig. 5, the width direction of the power supply device 100 is the y direction in fig. 5, the thickness direction of the power supply device 100 is the direction perpendicular to both the x direction and the y direction, and the length direction, the width direction, and the thickness direction of the atomizing device 200 and the entire electronic atomizer coincide with the power supply device 100.

When the power supply device 100 is connected to the atomization device 200 at a first relative position, the shielding portion 110 is located at a position for shielding at least a part of the through-flow section of the airflow channel 230; when the power supply device 100 is connected to the atomizing device 200 at the second relative position, the shielding portion 110 is located at a position where it does not shield the cross section of the airflow channel 230.

The two relative positions correspond to two modes of inhaling gas by a user respectively. As shown in fig. 5, when the user uses the inhalation mode of mouth-inhaling, the user can connect the power supply device 100 and the atomization device 200 at a first relative position. At this time, the shielding portion 110 of the power supply device 100 shields a part of the gas flow passage 230, so that the cross-sectional area through which gas can flow in the gas flow passage 230 is reduced. When the user inhales at the aerosol outlet 220, the flow of breathable gas is correspondingly reduced.

When the user employs a lung inhalation mode, the user may connect the power supply device 100 and the atomizer device 200 in a second relative position, as shown in fig. 6. In this case, the airflow passage 230 is not blocked by the blocking portion 110 of the power supply device 100, and the area of the flow cross section of the airflow passage 230 is maximized. The flow of breathable gas is also maximized when the user inhales at the aerosol outlet 220.

Since the connection mode of the power supply device 100 and the atomization device 200 at two relative positions is a detachable connection mode, when a user needs to switch from an inhalation mode to another inhalation mode, the user only needs to detach the atomization device 200 from the currently connected relative position and then connect the atomization device 200 with the power supply device 100 at the other relative position.

When the power supply device is connected with the atomization device at a first relative position, the air inlet and the first airflow port are separated by the blocking structure; when the power supply device is connected with the atomization device at the second relative position, the air inlet and the first airflow port are separated by the blocking structure.

No matter the grafting mode of mouth-sucking, or the grafting mode of lung-sucking, air inlet and first air current mouth are all separated by the shielding part, and the air current near the air inlet can not produce the interference to first air current mouth like this to make the air current near first air current mouth more stable.

As shown in fig. 5 and fig. 6, in the present embodiment, a plug hole 231 is formed at an end of the airflow channel 230 facing the air inlet 210, and when the power supply device 100 is connected to the atomization device 200 at a first relative position, the shielding portion 110 is located in the plug hole 231; when the power supply device 100 is connected to the atomization device 200 at the second relative position, the shielding portion 110 is located outside the insertion hole 231.

In the present embodiment, the air inlet end of the air flow channel 230 is designed as a plug hole 231, and the tail end of the plug hole 231 is the air inlet 210. The shielding portion 110 of the power supply device 100 can be inserted into the insertion hole 231. When the user uses the mouth-sucking mode, the power supply device 100 is connected with the atomizing device 200 at a first relative position, and the inserting hole 231 can be used as an inserting positioning structure and a connecting structure. The user can insert the shielding portion 110 into the insertion hole 231, so that the power supply device 100 and the atomizing device 200 can be connected with high reliability and accurate positions. Meanwhile, since the shielding portion 110 is a part of the airflow channel 230, after the shielding portion 110 is inserted into the insertion hole 231, at least a part of the insertion hole 231 can be shielded, so that the other flow cross-sectional area in the airflow channel 230 is reduced. Wherein the size of the insertion hole 231 can be set according to the flow rate of the inhaled air when the user inhales the lung. And the size of the shielding part 110 can be designed according to the flow rate of the inhaled air when the user inhales.

In this embodiment, the atomization device 200 is further provided with a slot 232, the slot 232 is not communicated with the airflow channel 230, the slot 232 and the insertion hole 231 are located at the same end of the atomization device 200, and when the power supply device 100 is connected with the atomization device 200 at the second relative position, the shielding portion 110 is located in the insertion slot.

In this embodiment, the slot 232 and the insertion hole 231 may be disposed at the first end of the atomization device 200 connected to the power supply device 100. When the user uses the lung inhalation mode, the power supply device 100 is connected to the atomization device 200 at a first relative position, and the shielding portion 110 is located in the insertion hole 231 and shields a part of the airflow channel 230. When the user uses the mouth-inhaling mode, the power supply device 100 is connected to the atomizer 200 at the second relative position, the shielding portion 110 is located in the insertion slot 232, and the airflow passage 230 is not shielded. At this time, the insertion groove can be used as a limiting structure and a connecting structure, and the power supply device 100 and the atomization device 200 can be connected with the insertion groove 232 at a precise position and with high reliability through the shielding part 110.

When an electrical connection is required between the atomizer 200 and the power supply device 100, electrodes are often provided on the atomizer 200 and the power supply device 100, wherein the portion of the atomizer 200 where the electrodes contact the electrodes on the power supply is referred to herein as an electrode contact. The atomization device 200 often has a plurality of electrodes, one electrode contact for each electrode. In this embodiment, the electrode contact on the atomizer 200 is in the form of an axisymmetric step, that is, the projection of the electrode contact on the atomizer 200 on a reference plane perpendicular to the length direction of the electronic atomizer is symmetric about a certain symmetry axis on the reference plane.

With the foregoing configuration, when the difference between the first relative position and the second relative position of the atomizer 200 and the power supply device 100 is 180 degrees, the positions and shapes of the electrode contacts on the atomizer 200 are the same in the two different position connection manners described above for the electrode contacts. In this way, the electrode contacts on the atomizer device 200 can be electrically connected to the power supply device 100 reliably, regardless of whether the atomizer device 200 and the power supply device 100 are connected in the first relative position or the second relative position. As a preferred embodiment, the electrode contact on the power supply device 100 may also be arranged to be axisymmetric, and the axis of symmetry is the same as the axis of symmetry of the electrode contact on the atomizing device 200.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
