[0037] The present application proposes an electronic atomizer, which may include an atomizer unit, an electronic control unit, a connector, and a valve component. The electronic control unit is electrically connected to the atomizer unit. The two ends of the connector are respectively connected to the atomizer unit and the electronic control unit. The connector can switch between unfolding and bending. An airway is formed inside the connector, which connects the atomizer unit to the outside atmosphere. An active cavity is formed inside the connector, which is adjacent to the airway and has an opening connecting to the airway. The valve component is arranged in the active cavity. The valve component has a first configuration and a second configuration. The valve component can switch between the first configuration and the second configuration as the shape of the connector changes. The electronic atomizer has an unfolded state and a folded state. In the unfolded state, the connector is unfolded, the atomizer unit and the electronic control unit are separated from each other, the valve component is in the first configuration, and the valve component does not block the airway. In the folded state, the connector is bent, the valve component is in the second configuration, and a portion of the valve component extends into the airway through the opening and blocks the airway.
[0038] In the electronic atomizer of the present application, when the electronic atomizer is in the expanded state, the connecting part is expanded, the atomizing unit and the electronic control unit are separated from each other, the valve part is in the first configuration, the valve part does not close the airway, and the electronic atomizer can be inhaled; when the electronic atomizer is in the folded state, the connecting part is bent, the valve part is in the second configuration, part of the valve part extends into the airway through the opening and blocks the airway, and the electronic atomizer cannot be inhaled; thus, the electronic atomizer of the present application can control the valve part to switch between the first configuration and the second configuration by expanding or folding the connecting part, thereby controlling the opening or closing of the airway.
[0039] The electronic atomizer proposed in this application is introduced in detail below.
[0040] See also Figures 1 to 3 The electronic atomizer 100 of the present application includes an atomizing unit 110. The atomizing unit 110 is used to atomize the atomized matrix therein. The atomizing unit 110 may include an atomizing assembly, an atomizing chamber 112 is formed inside the atomizing assembly, and the atomizing unit 110 is provided with an air inlet 111 and a mist outlet 113. The air inlet 111, the atomizing chamber 112 and the mist outlet 113 are connected in sequence. The air inlet 111 is used for the inflow of the outside atmosphere, and the mist outlet 113 is used for the user to inhale the aerosol produced by the atomizing chamber 112.
[0041] See also Figures 1 to 3 The electronic atomizer 100 of the present application includes an electronic control unit 120, which is electrically connected to the atomizing unit 110 and can supply power to the atomizing unit 110 to control the operation of the atomizing unit 110. The electronic control unit 120 has a first through hole 121 and a second through hole 122 that are connected to each other, and both the first through hole 121 and the second through hole 122 can be connected to the outside atmosphere.
[0042] See also Figures 1 to 3The electronic atomizer 100 of the present application includes a connector 130. The two ends of the connector 130 are respectively connected to the atomization unit 110 and the electronic control unit 120. The wires of the electronic control unit 120 can pass through the connector 130 to connect to the atomization unit 110, and a channel for the wires to pass through can be formed inside the connector 130.
[0043] See also Figure 2 and Figure 3 An airway 131 is formed inside the connector 130, and the two ends of the airway 131 are respectively connected to the air inlet 111 and the second through hole 122. The connector 130 is provided with an air inlet hole 136 connected to the outside atmosphere, and the air inlet hole 136 is connected to the airway 131. When the user inhales, the external air flow flows into the airway 131 through the air inlet hole 136, and the aerosol in the atomization chamber 112 is driven by the outside atmosphere to flow out from the mist outlet 113. The electronic atomizer 100 of the present application includes an air pressure sensor 150. The air pressure sensor 150 is arranged in the electronic control unit 120, and one side of the air pressure sensor 150 is connected to the first through hole 121, and the other side is connected to the airway 131. The electronic control unit 120 is used to start the atomization unit 110 in response to the sensor signal obtained by the air pressure sensor 150. When the user inhales, negative pressure is generated in the airway 131, triggering the air pressure sensor 150, which transmits an electrical signal to the electronic control unit 120, which activates the atomization unit 110. The air pressure sensor 150 may be a microphone.
[0044] See also Figure 2 and Figure 3 The connecting member 130 can be bent, so that the electronic atomizer 100 of the present application can be unfolded or folded. The connecting member 130 can be made of a flexible material (such as silicone, plastic or rubber material), and the connecting member 130 can also be a multi-pleated structure.
[0045] See also Figure 2 and Figure 3 The connector 130 has an internal active cavity 132 formed therein. The active cavity 132 is adjacent to the airway 131 and has an opening 133 communicating with the airway 131. The wall of the opening 133 on the side close to the active cavity 132 extends toward the active cavity 132 to form a guide channel 134. The inner wall of the guide channel 134 is gradually expanded in the direction toward the active cavity 132. Thus, the guide channel 134 can guide and limit the movement of other components within the opening 133. Figure 3 In the folded state, the end surface of the guide channel 134 near the active chamber 132 is sealed to the valve member 140. The inner wall of the guide channel 134 and the inner wall of the opening 133 are also sealed to the valve member 140. This improves the sealing between the active chamber 132 and the air passage 131, preventing the air passage 131 from communicating with the outside atmosphere through the active chamber 132.
[0046] See also Figures 2 to 5 The electronic atomizer 100 of the present application includes a valve member 140, which is disposed in the active chamber 132. The valve member 140 has a first configuration (eg Figure 4 As shown) and the second configuration (as Figure 5 As shown in FIG, the valve member 140 can switch between the first configuration and the second configuration following the change in the shape of the connecting member 130.
[0047] The electronic atomizer 100 has an unfolded state and a folded state. Figure 1 and Figure 2 In the expanded state, the connecting member 130 is expanded, the atomizing unit 110 and the electronic control unit 120 are separated from each other, and the valve member 140 is in the first configuration (eg Figure 2 and Figure 4 As shown), the valve member 140 does not block the airway 131, and the electronic atomizer 100 can be inhaled. Figure 3 In the folded state, the connecting member 130 is bent and the valve member 140 is in a second configuration (eg Figure 3 and Figure 5 As shown in FIG. 1 , a portion of the valve member 140 (specifically, the plug 143) extends into the airway 131 through the opening 133 and blocks the airway 131, preventing the electronic atomizer 100 from being inhaled. Thus, the electronic atomizer 100 of the present application can control the valve member 140 to switch between the first configuration and the second configuration by unfolding or folding the connector 130, thereby controlling the opening or closing of the airway 131.
[0048] See also Figure 1 and Figure 2 In the unfolded state, the connecting member 130 can be curved or straight, which is convenient for the user to suck. Figure 3 In the folded state, the connector 130 may be U-shaped, V-shaped, or C-shaped, thereby facilitating the storage of the electronic atomizer 100. In the folded state of the electronic atomizer 100, the atomization unit 110 and the electronic control unit 120 may be connected to each other or face each other in the air.
[0049] See also Figure 2 In one embodiment, in the unfolded state, a portion of the valve member 140 is inserted into the opening 133. Thus, when the user folds the electronic atomizer 100, the portion of the valve member 140 does not need to be aligned before entering the opening 133. This ensures that the portion of the valve member 140 can extend into the airway 131 through the opening 133 when folded. The extended end of the portion of the valve member 140 can be located in the opening 133 or in the airway 131.
[0050] See also Figure 2 and Figure 3The side of the active chamber 132 away from the airway 131 extends through the connector 130 to communicate with the outside world. The connector 130 includes a cover plate 135, which covers the side of the active chamber 132 that communicates with the outside world, thereby facilitating the preparation of the active chamber 132 and the installation of the valve component 140 in the active chamber 132. When the valve component 140 switches between the first configuration and the second configuration, the cover plate 135 can limit the valve component 140 to prevent the valve component 140 from being separated from the active chamber 132, thereby assisting the valve component 140 in switching between the first configuration and the second configuration. The cover plate 135 can be made of the same material as the other parts of the connector 130, or different materials. The cover plate 135 and the wall of the active chamber 132 can be snap-fitted or bonded. The cover plate 135 and the wall of the active chamber 132 can be sealed or non-sealed. While the active chamber 132 and the air passage 131 are sealed, the cover plate 135 and the wall of the active chamber 132 can preferably be in a non-sealed connection. In other words, a gap exists between the cover plate 135 and the wall of the active chamber 132, allowing the active chamber 132 to communicate with the outside atmosphere. As a result, the air pressure within the active chamber 132 remains stable during the expansion or flexion of the connector 130, and the gas within the active chamber 132 minimally interferes with the switching of the valve member 140 between the first and second configurations.
[0051] See also Figures 2 to 5 The valve member 140 includes a first spring piece 141, a second spring piece 142 and a plug 143. The first spring piece 141 and the second spring piece 142 are installed in the movable chamber 132. One end of the second spring piece 142 is connected to one end of the first spring piece 141, and the other end of the second spring piece 142 is a free end. One end of the plug 143 is connected to the middle of the second spring piece 142. The plug 143 is movably installed in the through hole 133. Figure 2 In the expanded state, the first elastic piece 141 and the second elastic piece 142 expand along with the connecting piece 130. The middle part of the second elastic piece 142 bulges away from the air passage 131 and abuts against the connecting piece 130 (specifically, the cover plate 135). The plug 143 does not block the air passage 131. Figure 3 In the folded state, the middle part of the second elastic piece 142 bends in the same direction as the connecting member 130, the free end is tilted away from the airway 131 and abuts against the wall (or cover plate 135) of the active cavity 132, and the plug 143 extends into the airway 131 through the opening 133 and blocks the airway 131.
[0052] See also Figure 4 and Figure 5In one embodiment, the first spring piece 141, the second spring piece 142, and the plug 143 can be integrally formed. This ensures a tight connection between the first spring piece 141, the second spring piece 142, and the plug 143, resulting in relatively stable deformation of the valve member 140 and stable functioning of the valve member 140. The first spring piece 141, the second spring piece 142, and the plug 143 can be made of a metal material. In another embodiment, the first spring piece 141, the second spring piece 142, and the plug 143 can be detachably connected (e.g., by snapping, bonding, screwing, or welding). The first spring piece 141, the second spring piece 142, and the plug 143 can be made of the same material. Alternatively, the first spring piece 141, the second spring piece 142, and the plug 143 can be made of different materials. The elastic moduli of the plug 143, the first spring piece 141, and the second spring piece 142 can increase in sequence, thereby facilitating the functioning of each.
[0053] Please combine Figures 2 to 5 The first elastic leaf 141 can provide support for the deformation of the second elastic leaf 142. During the process of switching the valve member 140 from the first configuration to the second configuration, the first elastic leaf 141 at least partially abuts the wall of the movable chamber 132. A clearance opening 411 can be defined in the middle of the first elastic leaf 141. The middle of the second elastic leaf 142 opposes the clearance opening 411, and the plug 143 is movably disposed through the clearance opening 411. As a result, the valve member 140 has a compact structure and a stable center of gravity, effectively switching between the first and second configurations. The orthographic projection of the free end of the second elastic leaf 142 toward the airway 131 falls on the first elastic leaf 141. As a result, the first elastic leaf 141, the wall of the movable chamber 132, and the cover plate 135 can work together to enable the first elastic leaf 141 to effectively drive the plug 143 to move.
[0054] See also Figure 4 and Figure 5 The first spring piece 141 is provided with a stress groove 412. The stress groove 412 is provided at the end of the first spring piece 141 that is not connected to the second spring piece 142. One end of the stress groove 412 is connected to the avoidance opening 411, and the other end of the stress groove 412 extends out of the first spring piece 141. The provision of the stress groove 412 can prevent the first spring piece 141 from breaking due to multiple deformations. Figure 5 The shape of the stress groove 412 can be irregular. The stress groove 412 divides the end of the first elastic piece 141 that is not connected to the second elastic piece 142 into two staggered parts, thereby preventing the stress groove 412 from causing a significant reduction in the rigidity of the first elastic piece 141.
[0055] Please combine Figures 2 to 5 The deformation of the second elastic piece 142 can drive the plug 143 to move. Figure 2In the expanded state (the first configuration of the valve member 140), the middle portion of the second elastic piece 142 on the side facing away from the airway 131 abuts against the cover plate 135, and the connection state of the second elastic piece 142 in the active cavity 132 is stable. Figure 4 In the folded state (the second configuration of the valve member 140), the free end of the second elastic piece 142 abuts against the wall of the active cavity 132 (or the cover plate 135), and the connection state of the second elastic piece 142 in the active cavity 132 is stable. Preferably, in the second configuration, the free end of the second elastic piece 142 abuts against the wall of the active cavity 132, thereby preventing the cover plate 135 from being pushed open by the free end of the second elastic piece 142 when the connecting member 130 is bent.
[0056] See also Figure 4 and Figure 5 At least two stress holes 421 are hollowed out on the second elastic piece 142, and the at least two stress holes 421 are located on both sides of the plug 143. Therefore, it is easier for the second elastic piece 142 to deform along with the connecting piece 130.
[0057] The plug 143 is used to move in the opening 133 to open or close the airway 131. Figure 3 In the folded state (the second configuration of the valve member 140), the plug 143 is sealed against the wall of the airway 131. To improve the sealing performance, the plug 143 and the airway 131 may be in interference fit. Figure 2 and Figure 3 The plug 143 is tapered away from the second elastic piece 142. This facilitates insertion of the plug 143 into and movement within the opening 133. The shape of the plug 143 matches the cross-sectional shape of the opening 133 and the airway 131. The plug 143 may be in the form of a sheet, a column, or a block.
