Abstract
Description
Technical Field
[0001] This application relates to the field of atomization technology, and in particular to an electronic atomizer. Background Technology
[0002] Some e-cigarettes are designed with a foldable structure for easy storage. However, in existing foldable e-cigarettes, the atomizing unit and the electronic control unit are generally connected by a hinge, resulting in a relatively crude structure. The internal airflow configuration is not significantly different from that of non-foldable e-cigarettes. Utility Model Content
[0003] The main objective of this application is to provide an electronic atomizer that can control the opening or closing of the airway by switching between unfolding and folding.
[0004] To achieve the above objectives, this application proposes an electronic atomizer, the electronic atomizer comprising:
[0005] Atomizing unit;
[0006] The electronic control unit is electrically connected to the atomizing unit;
[0007] A connector, with its two ends connected to the atomizing unit and the electronic control unit respectively, is capable of switching between unfolding and bending. An air passage is formed inside the connector, connecting the atomizing unit to the outside atmosphere. A movable cavity is formed inside the connector, adjacent to the air passage and having an opening connecting to the air passage; and
[0008] A valve component is disposed in the movable 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 in accordance with the shape change of the connecting member.
[0009] The electronic atomizer has an unfolded state and a folded state. In the unfolded state, the connector is unfolded, the atomizing unit and the electronic control unit are far apart, the valve is in the first configuration, and the valve does not close the air passage. In the folded state, the connector is bent, the valve is in the second configuration, and a portion of the valve extends into the air passage through the opening and blocks the air passage.
[0010] Optionally, in the deployed state, a portion of the valve is inserted into the port, with the extended end of the portion of the valve located within the port; or a portion of the valve extends into the air passage via the port, with the extended end of the portion of the valve located within the air passage.
[0011] Optionally, the wall of the opening on the side near the movable cavity extends toward the movable cavity to form a guide channel, and the inner wall of the guide channel is gradually widened in the direction toward the movable cavity.
[0012] Optionally, the side of the active cavity away from the air passage extends through the connector to communicate with the outside. The connector includes a cover plate that covers the side of the active cavity that communicates with the outside. The cover plate can assist the valve in switching between the first configuration and the second configuration.
[0013] Optionally, the valve component includes a first spring, a second spring, and a plug. The first and second springs are installed in the movable cavity. One end of the second spring is connected to one end of the first spring, and the other end of the second spring is a free end. One end of the plug is connected to the middle of the second spring, and the plug is movably inserted through the opening. In the unfolded state, the first and second springs unfold with the connector. The middle of the second spring bulges away from the air passage and abuts against the connector. The plug does not block the air passage. In the folded state, the middle of the second spring bends in the same direction as the connector. The free end bulges away from the air passage and abuts against the wall of the movable cavity. The plug extends into the air passage through the opening and blocks the air passage.
[0014] Optionally, the first spring has a clearance opening in the middle, the middle of the second spring is opposite to the clearance opening, the plug moves through the clearance opening, and the free end of the second spring projects a positive projection onto the first spring towards the air passage.
[0015] Optionally, the first spring sheet has a stress groove, which is located at the end of the first spring sheet that is not connected to the second spring sheet. One end of the stress groove is connected to the clearance opening, and the other end of the stress groove extends out of the first spring sheet.
[0016] Optionally, the second spring sheet has at least two stress holes drilled out, the at least two stress holes being located on both sides of the plug.
[0017] Optionally, the plug is tapered in a direction away from the second spring.
[0018] Optionally, the first spring, the second spring, and the plug are integrally formed.
[0019] In the electronic atomizer of this application, when the atomizer is in the unfolded state, the connector is unfolded, the atomizing unit and the electronic control unit are separated, and the valve is in a first configuration, where the valve does not close the airway, and the electronic atomizer can be inhaled. When the electronic atomizer is in the folded state, the connector is bent, the valve is in a second configuration, and part of the valve extends into the airway through the opening and blocks the airway, preventing the electronic atomizer from being inhaled. Thus, the electronic atomizer of this application can control the valve to switch between the first and second configurations by unfolding or folding the connector, thereby controlling the opening or closing of the airway.

[0033] This application discloses an electronic atomizer, which may include an atomizing unit, an electronic control unit, a connector, and a valve. The electronic control unit is electrically connected to the atomizing unit. The connector is connected to the atomizing unit and the electronic control unit at its two ends, respectively. The connector can switch between unfolded and bent states. An air passage is formed inside the connector, connecting the atomizing unit to the outside atmosphere. A movable cavity is formed inside the connector, adjacent to the air passage and having an opening connecting to the air passage. The valve is located in the movable cavity and has a first configuration and a second configuration. The valve can switch between the first and second configurations according to the shape change of the connector. The electronic atomizer has an unfolded state and a folded state. In the unfolded state, the connector is unfolded, the atomizing unit and the electronic control unit are far apart, and the valve is in the first configuration, without blocking the air passage. In the folded state, the connector is bent, the valve is in the second configuration, and a portion of the valve extends into the air passage through the opening and blocks the air passage.
[0034] In the electronic atomizer of this application, when the electronic atomizer is in the unfolded state, the connector is unfolded, the atomizing unit and the electronic control unit are far apart, the valve is in a first configuration, the valve does not close the airway, and the electronic atomizer can be inhaled; when the electronic atomizer is in the folded state, the connector is bent, the valve is in a second configuration, part of the valve extends into the airway through the opening and blocks the airway, and the electronic atomizer cannot be inhaled; thus, the electronic atomizer of this application can control the valve to switch between the first configuration and the second configuration by unfolding or folding the connector, thereby controlling the opening or closing of the airway.
[0035] The electronic atomizer proposed in this application will be described in detail below.
[0036] Please see Figures 1 to 3 The electronic atomizer 100 of this application includes an atomizing unit 110. The atomizing unit 110 is used to atomize the atomizing matrix inside it. The atomizing unit 110 may include an atomizing component, the atomizing component having an atomizing chamber 112 formed inside. The atomizing unit 110 has an air inlet 111 and a mist outlet 113, and the air inlet 111, the atomizing chamber 112, and the mist outlet 113 are connected in sequence. The air inlet 111 is used to allow outside air to flow in, and the mist outlet 113 is used for the user to inhale the mist generated by the atomizing chamber 112.
[0037] Please see Figures 1 to 3 The electronic atomizer 100 of this application includes an electronic control unit 120, which is electrically connected to an atomizing unit 110. The electronic control unit 120 can supply power to the atomizing unit 110 to control its operation. The electronic control unit 120 has a first through hole 121 and a second through hole 122, both of which can be connected to the outside atmosphere.
[0038] Please see Figures 1 to 3 The electronic atomizer 100 of this application includes a connector 130. The two ends of the connector 130 are respectively connected to an atomizing unit 110 and an electronic control unit 120. The wires of the electronic control unit 120 can pass through the connector 130 to connect to the atomizing unit 110, and a channel for the wires to pass through is formed inside the connector 130.
[0039] Please see Figure 2 and Figure 3The connector 130 has an air passage 131 inside, with its two ends connected to an air inlet 111 and a second through hole 122, respectively. The connector 130 has an air inlet 136 that connects to the outside atmosphere, and the air inlet 136 connects to the air passage 131. When the user inhales, the outside airflow flows into the air passage 131 through the air inlet 136, and the atomized mist in the atomizing chamber 112 is carried out from the mist outlet 113 by the outside atmosphere. The electronic atomizer 100 of this application includes a pressure sensor 150. The pressure sensor 150 is located in the electronic control unit 120, with one side connected to the first through hole 121 and the other side connected to the air passage 131. When the user inhales, a negative pressure is generated in the air passage 131, triggering the pressure sensor 150. The pressure sensor 150 transmits an electrical signal to the electronic control unit 120, which then starts the atomizing unit 110. The pressure sensor 150 can be a microphone.
[0040] Please see Figure 2 and Figure 3 The connector 130 is flexible, thereby allowing the electronic atomizer 100 of this application to be unfolded or folded. The connector 130 may be made of a flexible material (such as silicone, plastic or rubber), and the connector 130 may also have a multi-pleated structure.
[0041] Please see Figure 2 and Figure 3 The connector 130 has a movable cavity 132 inside, which is adjacent to the air passage 131 and has an opening 133 that connects to the air passage 131. The wall of the opening 133 on the side closest to the movable cavity 132 extends toward the movable cavity 132 to form a guide channel 134, and the inner wall of the guide channel 134 gradually widens in the direction toward the movable cavity 132. Thus, the guide channel 134 can guide and limit the movement of other components within the opening 133.
[0042] Please see Figures 2 to 5 The electronic atomizer 100 of this application includes a valve component 140, which is disposed in the movable cavity 132 and has a first configuration (e.g., Figure 4 (as shown) and second configuration (as shown) Figure 5 As shown, the valve component 140 can switch between a first configuration and a second configuration as the shape of the connecting component 130 changes.
[0043] The electronic atomizer 100 has an unfolded state and a folded state. Please refer to [link / reference]. Figure 1 and Figure 2 In the unfolded state, the connector 130 is unfolded, the atomizing unit 110 and the electronic control unit 120 are separated from each other, and the valve component 140 is in the first configuration (e.g. Figure 2 and Figure 4 As shown), valve 140 does not seal the air passage 131, allowing the electronic atomizer 100 to be drawn in. Please refer to [link / reference]. Figure 3 In the folded state, connector 130 is bent, and valve component 140 is in a second configuration (e.g.) Figure 3 and Figure 5 As shown, a portion of the valve element 140 (specifically, a plug 143) extends into the airway 131 through the port 133 and blocks the airway 131, preventing the electronic atomizer 100 from being inhaled. Therefore, by unfolding or folding the connector 130, the electronic atomizer 100 of this application can control the valve element 140 to switch between a first configuration and a second configuration, thereby controlling the opening or closing of the airway 131.
[0044] Please see Figure 1 and Figure 2 In the unfolded state, the connector 130 can be curved or straight, thus facilitating suction for the user. (See also...) Figure 3 In the folded state, the connector 130 can be U-shaped, V-shaped, or C-shaped, which facilitates the storage of the electronic atomizer 100. In the folded state of the electronic atomizer 100, the atomizing unit 110 and the electronic control unit 120 can be connected to each other or positioned opposite each other in the air.
[0045] Please see Figure 2 In one embodiment, in the unfolded state, a portion of the valve component 140 is inserted into the port 133. Therefore, when the user folds the electronic atomizer 100, the portion of the valve component 140 does not need to be aligned before entering the port 133, ensuring that the portion of the valve component 140 can extend into the air passage 131 via the port 133 during folding. The extended end of the valve component 140 can be located either within the port 133 or within the air passage 131.
[0046] Please see Figure 2 and Figure 3 The movable cavity 132 extends through the connector 130 on the side away from the airway 131 to communicate with the outside. The connector 130 includes a cover plate 135, which covers the side of the movable cavity 132 that communicates with the outside, thereby facilitating the fabrication of the movable cavity 132 and the installation of the valve component 140 within the movable cavity 132. When the valve component 140 switches between a first configuration and a second configuration, the cover plate 135 can limit the valve component 140 to prevent it from disengaging from the movable cavity 132, thus assisting the valve component 140 in switching between the first and second configurations. The cover plate 135 and other parts of the connector 130 may be made of the same or different materials. The cover plate 135 and the wall of the movable cavity 132 may be snap-fitted or bonded.
[0047] Please see Figures 2 to 5The valve component 140 includes a first spring 141, a second spring 142, and a plug 143. The first spring 141 and the second spring 142 are installed in the movable cavity 132. One end of the second spring 142 is connected to one end of the first spring 141, and the other end of the second spring 142 is a free end. One end of the plug 143 is connected to the middle of the second spring 142, and the plug 143 is movably inserted through the opening 133. Please refer to [link / reference]. Figure 2 In the deployed state, the first spring 141 and the second spring 142 unfold along with the connector 130. The middle part of the second spring 142 protrudes away from the air passage 131 and abuts against the connector 130 (specifically, it can be a cover plate 135). The plug 143 does not seal the air passage 131. Please refer to [link / reference]. Figure 3 In the folded state, the middle part of the second spring 142 bends in the same direction as the connector 130, the free end is raised away from the airway 131 and abuts against the wall (or cover plate 135) of the movable cavity 132, and the plug 143 extends into the airway 131 through the opening 133 and blocks the airway 131.
[0048] Please see Figure 4 and Figure 5 In one embodiment, the first spring 141, the second spring 142, and the plug 143 can be integrally formed. This ensures a tight connection between the first spring 141, the second spring 142, and the plug 143, resulting in more stable deformation of the valve component 140 and enabling it to function reliably. The first spring 141, the second spring 142, and the plug 143 can be made of metallic materials. In another embodiment, the first spring 141, the second spring 142, and the plug 143 are detachably connected (e.g., by snap-fit, bonding, screw connection, or welding). The first spring 141, the second spring 142, and the plug 143 can be made of the same material. Alternatively, the materials can be different, and the elastic modulus of the plug 143, the first spring 141, and the second spring 142 can increase sequentially, thereby facilitating the proper functioning of each component.
[0049] Please combine Figures 2 to 5The first spring plate 141 provides support for the deformation of the second spring plate 142. During the switching of the valve component 140 from the first configuration to the second configuration, the first spring plate 141 at least partially abuts against the wall of the movable cavity 132. A clearance opening 411 can be formed in the middle of the first spring plate 141, and the middle of the second spring plate 142 is opposite to the clearance opening 411. The plug 143 is movably inserted through the clearance opening 411. Thus, the valve component 140 has a compact structure and a stable center of gravity, and the switching effect between the first and second configurations is good. The orthographic projection of the free end of the second spring plate 142 toward the air passage 131 falls on the first spring plate 141. Thus, the first spring plate 141, the wall of the movable cavity 132, and the cover plate 135 can work together to enable the first spring plate 141 to play a better role in driving the movement of the plug 143.
[0050] Please see Figure 4 and Figure 5 The first spring piece 141 has a stress groove 412, which is located at the end of the first spring piece 141 not connected to the second spring piece 142. One end of the stress groove 412 connects to the clearance opening 411, and the other end extends out of the first spring piece 141. The stress groove 412 prevents the first spring piece 141 from breaking due to repeated deformation. Please refer to [link / reference]. Figure 5 The shape of the stress groove 412 can be irregular. The stress groove 412 makes the end of the first spring piece 141 that is not connected to the second spring piece 142 into two staggered parts, thereby avoiding the stress groove 412 from causing a significant reduction in the rigidity of the first spring piece 141.
[0051] Please combine Figures 2 to 5 The deformation of the second spring 142 can drive the movement of the plug 143. (See also...) Figure 2 In the deployed state (first configuration of valve 140), the middle portion of the side of the second spring 142 opposite to the air passage 131 abuts against the cover plate 135, and the connection state of the second spring 142 within the movable cavity 132 is stable. (See also...) Figure 4 In the folded state (second configuration of valve 140), the free end of the second spring 142 abuts against the wall (or cover plate 135) of the movable cavity 132, and the connection state of the second spring 142 within the movable cavity 132 is stable. Preferably, in the second configuration, the free end of the second spring 142 abuts against the wall of the movable cavity 132, so that the cover plate 135 will not be pushed open by the free end of the second spring 142 when the connector 130 is bent.
[0052] Please see Figure 4 and Figure 5 The second spring piece 142 has at least two stress holes 421 cut out, and the at least two stress holes 421 are located on both sides of the plug 143. As a result, the second spring piece 142 can deform more easily along with the connecting piece 130.
[0053] The plug 143 is movable within the opening 133 to open or close the air passage 131. See also... Figure 3 In the folded state (second configuration of valve 140), the plug 143 is sealed to the wall of the air passage 131. To improve sealing, the plug 143 and the air passage 131 can be an interference fit. See also... Figure 2 and Figure 3 The plug 143 is tapered away from the second spring 142. This facilitates the insertion of the plug 143 into the port 133 and its movement within the port 133. The shape of the plug 143 is adapted to the cross-sectional shape of the port 133 and the air passage 131. The plug 143 can be a sheet-like structure, a columnar structure, or a block-like structure.
[0054] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
