[0002] An electronic atomizer is an electronic device that atomizes a vapor medium into a mist. The atomizing mechanism of an electronic atomizer draws in e-liquid from the reservoir and, powered by a power supply, atomizes the vapor medium. The mist then flows out through the mouthpiece connected to the atomizing chamber for the user to inhale. However, current electronic atomizers are assembled as a single unit at the factory, and the atomizing mechanism is not detachable. The reservoir and the atomizing mechanism are continuously connected, making it prone to leakage when environmental pressure or temperature changes, and the atomizing mechanism cannot be replaced.

[0032] This application discloses an electronic atomizer, comprising a housing, an outlet tube, a sealing assembly, a sealing cylinder, a connecting cylinder, and an atomizing device. The housing has openings at both ends. The outlet tube has openings at both ends, is located inside the housing, and its top end is fitted onto the top end of the housing, forming an oil storage chamber between the housing and the outlet tube. The sealing assembly includes a sealing cover and a pull rod. The sealing cover is located inside the housing, and its top end is fitted onto the bottom end of the outlet tube, slidably connected to the outlet tube. The pull rod passes through the outlet tube and is slidably connected to it, with its bottom end extending out of the outlet tube and into the sealing cover; the bottom end of the pull rod is detachably connected to the sealing cover. The sealing cylinder is at least partially located inside the housing and fitted onto it. The connecting cylinder is fitted into the sealing cover and its bottom end is fixedly connected to the sealing cylinder, slidably connected to the sealing cover, and has an oil passage hole on it. The atomizing device has an oil inlet, and an atomizing chamber is formed inside the atomizing device; the atomizing device is detachably connected to the connecting cylinder. The electronic atomizer has a detached state and an assembled state. In the detached state, the sealing component is in the first position, the oil passage is closed by the sealing cover, and the sealing cylinder, sealing component, and connecting cylinder work together to seal the oil storage chamber. In the assembled state, the atomizing device is connected to the connecting cylinder, the sealing cover is in the second position, the height of the second position is greater than the height of the first position, the sealing cover opens to close the oil passage, the oil storage chamber, oil passage, and oil inlet are connected to form an oil inlet channel, the atomizing device closes the connection between the oil storage chamber and the outside, the pull rod detaches from the sealing cover, and the mist outlet tube, sealing cover, and atomizing chamber are connected to form a mist outlet channel.

[0033] In the electronic atomizer of this application, when the atomizing device is not connected to the connecting tube, the sealing component is in the first position, the oil passage is closed by the sealing cover, and the sealing tube, sealing component, and connecting tube work together to seal the oil storage chamber, thus preventing leakage of the atomizing matrix in the oil storage chamber. When the atomizing device is connected to the connecting tube, the sealing cover moves upward and opens the seal on the oil passage, connecting the oil storage chamber, the oil passage, and the oil inlet to form an oil inlet channel, allowing the atomizing matrix in the oil storage chamber to flow into the atomizing device. The atomizing device then seals the connection between the oil storage chamber and the outside, preventing leakage of the atomizing matrix. After the pull rod detaches from the sealing cover, the mist outlet tube, the sealing cover, and the atomizing chamber connect to form a mist outlet channel, allowing the atomized mist in the atomizing chamber to flow into the mist outlet tube and be further inhaled by the user. In summary, the atomizing device of the electronic atomizer of this application can be reassembled before use, reducing the occurrence of oil leakage, and the atomizing device can also be replaced.

[0034] The following will mainly describe the specific structure of the electronic atomizer.

[0035] Please see Figures 1 to 3 The electronic atomizer 100 of this application includes a housing 110, with openings at both ends. The housing 110 may be cylindrical, such as a cylindrical, elliptical, or square prism.

[0036] Please see Figures 1 to 3 The electronic atomizer 100 of this application includes a mist outlet tube 120, which has openings at both ends. The cross-section of the mist outlet tube 120 can be circular or elliptical. The mist outlet tube 120 is disposed inside a housing 110, and the top end of the mist outlet tube 120 is sleeved onto the top end of the housing 110. The top end of the mist outlet tube 120 can extend beyond the top end of the housing 110, be located inside the top end of the housing 110, or be flush with the top end of the housing 110 (e.g., ...). Figures 1 to 3 (As shown). The housing 110 and the mist outlet pipe 120 can be integrally formed (e.g. Figures 1 to 3 (As shown). Of course, the housing 110 and the mist outlet pipe 120 can also be detachably connected, such as by snap-fit, adhesive or screw connection.

[0037] Please see Figure 1 and Figure 2 An oil storage chamber 180 is formed between the housing 110 and the mist outlet pipe 120. The oil storage chamber 180 is used to store the atomizing matrix. The shape of the oil storage chamber 180 is defined by the housing 110 and the mist outlet pipe 120, and is generally cylindrical.

[0038] Please see Figures 1 to 3The electronic atomizer 100 of this application includes a sealing assembly 130, which includes a sealing cover 131. The sealing cover 131 is disposed inside the housing 110, and the top end of the sealing cover 131 is sleeved outside the bottom end of the mist outlet tube 120. The sealing cover 131 is slidably connected to the mist outlet tube 120. The sealing cover 131 includes a first cylindrical portion 133 and a second cylindrical portion 134. The diameter of the first cylindrical portion 133 is smaller than the diameter of the second cylindrical portion 134. The bottom end of the first cylindrical portion 133 is connected to the top end of the second cylindrical portion 134. The inner wall of the first cylindrical portion 133 is slidably connected to the outer wall of the mist outlet tube 120, and the inner wall of the second cylindrical portion 134 is slidably connected to the outer wall of the connecting tube 150 (described in detail below).

[0039] Please see Figures 1 to 3 The sealing assembly 130 includes a pull rod 132, which passes through the mist outlet pipe 120 and is slidably connected to it. The bottom end of the pull rod 132 extends out of the mist outlet pipe 120 and into the sealing cover 131. The bottom end of the pull rod 132 is detachably connected to the sealing cover 131 (specifically, the top end of the second cylindrical section 134). Please refer to [link / reference]. Figures 1 to 3 Understandably, the pull rod 132 is fitted inside the mist outlet pipe 120, and the first cylindrical part 133 is fitted outside the mist outlet pipe 120. Therefore, the diameter of the pull rod 132 is smaller than the diameter of the first cylindrical part 133.

[0040] There are several ways to detach the pull rod 132 from the sealing cover 131. In one embodiment, a weak connection is provided between the top end of the second cylindrical portion 134 and the bottom end of the pull rod 132, allowing the pull rod 132 to be detached from the sealing cover 131 by external force. The weak connection can be a thin-based structure with a thick base or a sheet-like / ring-like structure with multiple perforations. In another embodiment, the second cylindrical portion 134 and the pull rod 132 are threaded together, allowing the pull rod 132 to be detached from the sealing cover 131 by rotating it.

[0041] Please see Figures 1 to 3 The electronic atomizer 100 of this application includes a sealing cylinder 140, which is at least partially disposed within a housing 110 and sleeved onto the housing 110. The sealing cylinder 140 can be connected to a sealing cover 131 (specifically, a second cylinder portion 134), and the sealing cylinder 140 can also be spaced apart from the sealing cover 131 (e.g.,...). Figure 1 (As shown). The sealing cylinder 140 can be made of an elastic material (such as silicone, plastic or rubber).

[0042] Please see Figures 1 to 3The electronic atomizer 100 of this application includes a first sealing ring 191. The first sealing ring 191 is sleeved on the outside of the sealing cylinder 140, and is used to seal the connection between the sealing cylinder 140 and the housing 110. Therefore, the oil storage chamber 180 has good sealing performance and is not prone to oil leakage. The first sealing ring 191 can be made of elastic materials such as silicone, plastic, or rubber. A first sealing groove is formed on the outer wall of the sealing cylinder 140 corresponding to the inward indentation of the first sealing ring 191, and the first sealing ring 191 seals and connects to the first sealing groove.

[0043] Please see Figures 1 to 3 The electronic atomizer 100 of this application includes a connecting tube 150, which is sleeved inside a sealing cover 131 (specifically, a second tube portion 134), and the connecting tube 150 and the second tube portion 134 are slidably connected. A sealing tube 140 is fixedly connected to the bottom end of the connecting tube 150, and the connecting tube 150 and the sealing tube 140 can be connected by adhesive, snap-fit, or screw connection. Oil passage holes 151 are provided on the connecting tube 150, and the number of oil passage holes 151 can be multiple, arranged circumferentially along the connecting tube 150.

[0044] Please see Figures 1 to 3 The electronic atomizer 100 of this application includes an atomizing device 160, which is capable of atomizing an atomizing matrix. The atomizing device 160 has oil inlets 162, the number of which can be the same as the number of oil outlets 151, and the multiple oil inlets 162 are arranged circumferentially along the atomizing device 160. An atomizing chamber 163 is formed inside the atomizing device 160, and the atomizing device 160 is detachably connected to the connecting tube 150 (specifically, it can be a sleeve connection).

[0045] The electronic atomizer 100 has both a detached and an assembled state. Please refer to [link / reference]. Figure 1 In the detached state, the sealing component 130 is in the first position, the oil passage 151 is closed by the sealing cover 131, and the sealing cylinder 140, the sealing component 130 and the connecting cylinder 150 work together to seal the oil storage chamber 180, so that the atomizing matrix in the oil storage chamber 180 will not leak.

[0046] Please see Figure 2In the assembled state, the atomizing device 160 is connected to the connecting cylinder 150, and the sealing cover 131 is in the second position, with a height greater than that of the first position. The sealing cover 131 opens to close the oil passage 151, connecting the oil storage chamber 180, the oil passage 151, and the oil inlet 162 to form an oil inlet channel. The atomizing device 160 closes the connection between the oil storage chamber 180 and the outside world. The pull rod 132 detaches from the sealing cover 131, connecting the mist outlet pipe 120, the sealing cover 131, and the atomizing chamber 163 to form a mist outlet channel. Thus, the atomizing matrix in the oil storage chamber 180 can flow into the atomizing device 160, and the atomizing device 160 closes the connection between the oil storage chamber 180 and the outside world, preventing leakage of the atomizing matrix. The aerosol in the atomizing chamber 163 can flow into the mist outlet pipe 120 and be further inhaled by the user. During the sliding process of the sealing cover 131, the first cylinder 133 and the mist outlet pipe 120 remain sealed, so that the atomizing matrix will not leak from the first cylinder 133 and the mist outlet pipe 120, and the atomizing mist in the atomizing chamber 163 can also flow smoothly to the mist outlet pipe 120.

[0047] Please see Figures 1 to 3 The atomizing device 160 includes an atomizing component 161, which is capable of atomizing an atomizing substrate. The atomizing component 161 includes an atomizing core, an oil-guiding cotton, and an atomizing tube, which are sequentially nested from the inside out. An oil inlet 162 is opened in the atomizing tube of the atomizing component 161, and an atomizing chamber 163 is formed inside the atomizing component 161 (specifically, the atomizing core).

[0048] Please see Figures 1 to 3 The atomizing device 160 includes a mounting base 164. The bottom end of the atomizing component 161 is connected to the mounting base 164, which is used to seal the connection housing 110 and the sealing cylinder 140. The mounting base 164 includes an integrally formed main body 166 and a boss 167. The boss 167 is annular and fits around the bottom end of the main body 166. Please refer to [link / reference]. Figure 2 In one embodiment, the sealing cylinder 140 is disposed inside the housing 110. When the atomizing device 160 is connected to the connecting cylinder 150, the top surface of the main body 166 abuts against the bottom surface of the sealing cylinder 140, and the top surface of the boss 167 abuts against the bottom surface of the housing 110.

[0049] A first guide member is provided on the housing 110, and a second guide member is provided on the atomizing device 160. The first and second guide members can cooperate to guide the connection between the atomizing device 160 and the connecting cylinder 150. Thus, when the atomizing device 160 is connected to the connecting cylinder 150, the oil passage 151 and the oil inlet 162 can be aligned, allowing the atomizing matrix to flow smoothly from the oil storage chamber 180 into the atomizing device 160. The structures of the first and second guide members can vary and are not specifically limited.

[0050] Please see Figures 1 to 3In one embodiment, the first guide is a notch 111, which is formed at the bottom end of the housing 110. The atomizing device 160 (specifically, a mounting base 164) is connected to the bottom end of the housing 110. The second guide is a protrusion 165 that matches the notch 111. Please refer to [link / reference]. Figure 3 The protrusion 165 can be integrally formed with the mounting base 164. The bottom surface of the protrusion 165 is connected to the top surface of the boss portion 167, and the inner side of the protrusion 165 is connected to the outer side of the main body portion 166. Of course, the first guide member and the second guide member can also be other structures, such as a slider and a groove, respectively.

[0051] Please see Figures 1 to 3 The atomizing device 160 includes a second sealing ring 192, which is sleeved on the outside of the atomizing device 160 (specifically, the main body 166). The second sealing ring 192 is used to seal the connection between the housing 110 and the atomizing device 160. Therefore, the atomizing device 160 provides a good seal to the oil storage chamber 180, preventing the atomized matrix from leaking to the outside. The second sealing ring 192 can also be made of elastic materials such as silicone, plastic, or rubber. A second sealing groove is formed on the outer wall of the main body 166, corresponding to the inward indentation of the second sealing ring 192, and the second sealing ring 192 seals the connection to the second sealing groove.

[0052] Please see Figures 1 to 3 The electronic atomizer 100 also includes a mouthpiece 170, which is disposed at the top of the housing 110 and connects to the vapor outlet tube 120. In one embodiment, the mouthpiece 170 may be integrally formed from the top of the housing 110 and the top of the vapor outlet tube 120. Please refer to [link to relevant documentation]. Figures 1 to 3 In another embodiment, the mouthpiece 170 can be detachably connected to the housing 110, and the mouthpiece 170 is sleeved on the top of the housing 110.

[0053] Please see Figures 1 to 3 The outer wall of the top of the housing 110 is recessed downwards to form a mounting groove 113, and the bottom of the mounting groove 113 has an oil inlet 112 that connects to the oil storage chamber. The electronic atomizer 100 also includes a sealing plug 193, which is disposed in the mounting groove 113 and seals the oil inlet 112. The sealing plug 113 is detachably connected to the wall of the oil inlet 112. When the sealing plug 193 is disposed in the mounting groove 113, the sealing plug 193 can be press-fitted to the mounting groove 113, thereby improving the connection between the two and making the atomizing matrix less prone to leakage. The sealing plug 193 can also be made of elastic materials such as plastic, silicone, or rubber.

[0054] Please see Figures 1 to 3The mounting slot 113 is located above and connected to the mist outlet pipe 120. There are two oil inlets 112, located on opposite sides of the mist outlet pipe 120. The sealing plug 193 includes a connecting part 194 and two plug parts 195. The top ends of the two plug parts 195 are connected to the connecting part 194, and the bottom ends of the two plug parts 195 are respectively plugged into the two oil inlets 112. The connecting part 194 has a connecting port 196 that connects to the mist outlet pipe 120. Therefore, oil filling of the oil reservoir 180 is convenient, the atomizing matrix is ​​less prone to leakage, the atomization flow is smooth, and the structure of the electronic atomizer 100 is relatively compact.

[0055] Please see Figure 1 and Figure 2 When the mouthpiece 170 is connected to the housing 110, the mouthpiece 170 covers the sealing plug 193. As a result, the sealing plug 193 is less likely to be accidentally dislodged from the oil filling port 112, and the electronic atomizer 100 is also more aesthetically pleasing.

[0056] In the electronic atomizer 100 of this application, there are multiple ways to drive the sealing cover 131 to move from the first position to the second position.

[0057] Please see Figure 1 and Figure 2 In one embodiment, the top end of the pull rod 132 extends beyond the top end of the mouthpiece 170. The pull rod 132 is used to drive the sealing cover 131 to move along the axial direction of the mist outlet tube 120 toward the mouthpiece 170. After the atomizing device 160 is connected to the connecting tube 150, the user pulls the sealing cover 131 through the part of the pull rod 132 located outside the mouthpiece 170, opening the connection between the oil storage chamber 180 and the atomizing device 160, and separating the pull rod 132 from the sealing cover 131.

[0058] In another embodiment, the top end of the atomizing device 160 can abut against the bottom end of the pull rod 132. The atomizing device 160 is used to push the sealing assembly 130 to move along the axial direction of the mist outlet tube 120 toward the mouthpiece 170. After the atomizing device 160 is connected to the connecting tube 150, the top end of the pull rod 132 extends out of the mouthpiece 170. That is, during the connection process between the atomizing device 160 and the connecting tube 150, the atomizing device 160 pushes the sealing cover 131 to move. After the atomizing device 160 is connected to the connecting tube 150, the top end of the pull rod 132 extends out of the mouthpiece 170.
