Description

Technical Field

[0002] An electronic atomization device generally includes an atomizer for atomizing a liquid matrix to generate an aerosol, and a power supply mechanism for supplying power to the atomizer. In addition to being electrically connected, the atomizer and the power supply mechanism can also allow airflow to flow between the two, so that the airflow sensor provided in the power supply mechanism can sense the negative pressure generated by the atomizer suction, thereby triggering the electric drive to generate aerosol. In existing electronic atomization devices, external air flows into the atomizer through the matching gap between the power supply mechanism and the atomizer, and the assembly method between the atomizer and the power supply mechanism may structurally hinder the airflow sensor from detecting the airflow, thereby affecting the user's suction experience.

[0030] The present application is described in detail below with reference to the accompanying drawings and embodiments.

The electronic atomization device includes an atomizer 200 for atomizing a liquid matrix to generate an aerosol and a power supply mechanism 100 with a control function for providing electrical drive to the atomizer 200. In some embodiments, reference Figure 2 and Figure 3As shown, the power supply mechanism 100 includes a first shell 101, and a battery cell 115 for power supply, a charging module, and a control module for controlling the working state of the electronic atomization device contained in the first shell 101. The first shell 101 has a first end 1011 and a second end 1012 that are separated from each other in the longitudinal direction, and at least part of the first shell 101 is defined as a receiving cavity 102. In some embodiments, a bracket 103 for fixing the battery cell 115, the charging module, and the control module is also provided inside the first shell 101. The bracket 103 has a side wall 1033 that abuts against the inner wall of the first shell 101. The top of the bracket 103 defines at least part of the boundary of the receiving cavity 102 and is mainly used to achieve electrical connection with the atomizer 200. A fourth sealing member 109 is nested at the top of the bracket 103 to abut against the inner wall of the first shell 101, and is used to seal the connection gap between the first shell 101 and the bracket 103. The charging module includes a charging plate 118 and a charging interface 119 fixed on the charging plate 118. The charging plate 118 is fixed to the bottom of the bracket 103 and is used to be electrically connected to the control module and the battery cell 115. The second end 1012 of the first shell 101 is provided with a base 121, and the base 121 is snap-connected with the first shell 101. A plurality of shallow grooves are also provided on the wall where the base 121 contacts the charging interface 119, which can be used to receive a small amount of liquid matrix leaked from the charging interface 119 to prevent the liquid matrix from leaking to the outside of the power supply mechanism 100. Optionally, a longitudinally extending snap 1211 is provided on the base 121, which is snap-connected to the bottom of the bracket 103 so that the bracket 103 can be stably maintained inside the first shell 101. An opening is provided on the base 121 for exposing the charging interface 119. The side wall 1033 of the bracket 103, the top of the bracket 103 and the charging plate 118 enclose a battery cavity 123 for accommodating the battery cell 115. Optionally, a flexible element 117 is provided between the battery cell 115 and the charging plate 118 , so that even if the battery cell 115 is deformed to a certain extent during use, it will not cause squeezing damage to the charging plate 118 .

[0032] In some embodiments, the atomizer 200 is generally flat or cylindrical. Figure 4 and Figure 5As shown, the atomizer 200 includes a second shell 201 with a hollow interior, and the second shell 201 has a proximal end 2011 and a distal end 2012 arranged opposite to each other. The proximal end 2011 is generally flat or nozzle-shaped and has a hole formed to form an air outlet 202, and the aerosol can be output to the outside of the atomizer 200 for use by the user through the air outlet 202; the distal end 2012 is open to install other functional components of the atomizer 200. Optionally, when the atomizer 200 is in an idle state, the air outlet 202 can be closed by a first blocking member 207 to prevent the components in the atomizer 200 from being contaminated by the outside. A hollow tube 225 is provided in the second shell 201, and a mist guide channel is defined in the hollow tube 225. The hollow tube 225 is connected to the air outlet 202 through a second sealing member 213 and extends to the inside of the second shell 201 to provide a channel path for aerosol output. Optionally, a first liquid absorbing element 211 made of cotton or other materials is provided at the connection between the air outlet 202 and the second sealing member 213 to absorb condensed liquid near the air outlet 202 , thereby preventing liquid leakage at the air outlet 202 .

[0033] An annular liquid storage tube 205 is provided in the atomizer 200, and the outer surface of the liquid storage tube 205 abuts against the inner surface of the first housing 101, and is used to fix a liquid storage member 215 for storing a liquid matrix. One end of the liquid storage tube 205 is connected to the second sealing member 213, and the other end is connected to the third sealing member 227. The second sealing member 213 and the third sealing member 227 are generally sleeve-shaped, and are sealed and connected to the inner wall of the second housing 201, thereby defining and sealing a liquid storage cavity in the second housing 201.

[0034] The second shell 201 is also provided with an atomizing assembly for atomizing the liquid matrix to form an aerosol. The atomizing assembly includes a heating element 223 for heating the liquid matrix, and a liquid-conducting element 221 for absorbing and transferring the liquid matrix. In some embodiments, the heating element 223 can be a spiral heating wire or a heating net made of at least one of stainless steel, platinum-chromium alloy, iron-chromium-aluminum alloy, metal titanium, etc., and the liquid-conducting element 221 can be made of a material with excellent liquid storage performance having a capillary structure, such as non-woven fabrics, cotton, etc. The liquid-conducting element 221 can be fixedly arranged on the outside of the heating element 223, and the liquid-conducting element 221 extends longitudinally along the second shell 201; or, the heating element 223 is arranged around at least part of the surface of the liquid-conducting element 221, and the liquid-conducting element 221 is arranged vertically to the second shell 201. In some embodiments, the liquid-conducting element 221 may be a porous body made of a hard capillary structure such as porous ceramics, porous glass ceramics, porous glass, etc. The liquid-conducting element 221 is roughly block-shaped, and a heating element 223 is fixed on at least part of the surface of the liquid-conducting element 221. The heating element 223 may be a heating coating, a heating sheet, or a heating net. Among them, the heating coating may include but is not limited to electromagnetic induction heating coatings and infrared induction heating coatings. Alternatively, the heating element 223 may be formed on the surface of the porous body by mixing conductive raw material powder with a printing aid into a slurry and sintering it through printing.

[0035] The atomizing assembly further includes a support assembly for fixing the heating element 223 and the liquid guiding element 221. In some embodiments, the support assembly includes a generally tubular upper connecting seat 217 and a lower connecting seat 219 connected to the upper connecting seat 217. The liquid guiding element 221 is at least partially positioned on the upper connecting seat 217, and the heating element 223 is at least partially positioned on the lower connecting seat 219. The end of the hollow tube 225 away from the air outlet 202 is inserted into the upper connecting seat 217 and sealedly connected with the upper connecting seat 217. The annular wall of the upper connecting seat 217 is provided with a plurality of liquid guiding holes 2171 connected to the liquid storage cavity, and the liquid guiding element 221 communicates with the liquid storage cavity through the liquid guiding holes 2171, thereby absorbing the liquid matrix in the liquid storage cavity. One end of the lower connecting seat 219 abuts against the inner wall of the upper connecting seat 217, and the lower connecting seat 219 accommodates at least part of the inner cavity of the heating element 223 to form an atomizing cavity 237. The liquid matrix in the liquid storage chamber is absorbed by the liquid guide element 221 through the liquid guide hole 2171 and transferred to the heating element 223. The liquid matrix is ​​atomized by the heating element 223 to form an aerosol and stored in the atomization chamber 237. Further, the atomization chamber 237 is connected to the hollow tube 225 connected to the upper connecting seat 217, so that the aerosol stored in the atomization chamber 237 can be output through the fog guide channel in the hollow tube 225 for use by the user. The other end of the lower connecting seat 219 away from the upper connecting seat 217 is inserted in the third sealing member 227. Among them, the third sealing member 227 is provided with a fixing hole, which is sleeved on the outer wall of the support assembly of the atomization assembly, so as to achieve a sealed connection with the support assembly, and the third sealing member 227 is arranged below the liquid guide hole 2171 to prevent leakage of the liquid matrix.

[0036] The atomizer 200 further includes an end cap 231 disposed at the distal end 2012 of the second housing 201. The end cap 231 is mainly used to provide support for the third sealing member 227 and cover the open end of the second housing 201. The end cap 231 can be snapped onto the second housing 201. Optionally, a second liquid absorbing element 229 is disposed between the end cap 231 and the third sealing member 227, which is used to absorb the liquid matrix flowing out of the fixing hole of the third sealing member 227, thereby preventing liquid leakage. In some embodiments, a second electrode plug hole 247 is provided on the end cap 231, and a second conductive electrode 235 is correspondingly inserted into the second electrode plug hole 247. The heating element 223 is provided with an electrode pin and is electrically connected to the second conductive electrode 235 through a wire. In some embodiments, a vent 232 is also provided on the end cap 231 to allow air to enter the atomizer 200. Furthermore, a vent hole 220 is provided on the lower connecting seat 219 of the support assembly, and one end of the vent hole 220 of the lower connecting seat 219 is connected to the vent port 232, and the other end is connected to the atomizing chamber 237, so that air can enter the atomizing chamber 237 in the order of the vent port 232 and the vent hole 220. Optionally, when the atomizer 200 is in an idle state, the vent port 232 can be closed by the second blocking member 209 to prevent the components in the atomizer 200 from being contaminated by the outside.

[0037] In some embodiments, the atomizer 200 can be received in the receiving cavity 102 of the power mechanism 100 through the opening of the first housing 101 at the first end 1011. The receiving cavity 102 has an inner side surface connected to the opening and an inner bottom wall facing away from the opening. Figure 5 As shown, when the atomizer 200 is received in the receiving chamber 102, the top of the bracket 103 serves as the inner bottom wall of the receiving chamber 102, and at least one air inlet channel 243 is defined between the atomizer 200 and the inner side surface of the receiving chamber 102. In some embodiments, when the atomizer 200 is received in the receiving chamber 102, a plurality of air inlet channels 243 are defined between the atomizer 200 and the inner side surface of the receiving chamber 102, and the plurality of air inlet channels 243 are arranged at intervals around the circumference of the atomizer 200. At least one air inlet channel 243 extends at least partially along the longitudinal direction of the power supply mechanism 100 between the opening and the inner bottom wall, so as to provide a passage path for air to enter the atomizer 200. The inner side surface of the receiving chamber 102 has a gap or a gap between the opening and the atomizer 200, and the gap or the gap defines an air inlet 241 for external air to enter the air inlet channel 243.

[0038] In a preferred embodiment, the air inlet 241 is positioned near the proximal end 2011 of the second housing 201 of the atomizer 200. Figure 4 and Fig. 9, at least one ridge 106 is arranged on the outer surface of the second shell 201 of the atomizer 200, and the ridge 106 is close to the proximal end 2011 of the second shell 201. It is worth noting that in order to make the atomizer 200 achieve an interference fit with the first shell 101 at the air inlet 241, when the atomizer 200 is received in the receiving cavity 102, at least one ridge 106 is tightly combined with the inner surface of the receiving cavity 102, so that the atomizer 200 is stably maintained in the receiving cavity 102. In some embodiments, when the atomizer 200 is received in the receiving cavity 102, at least one ridge 106 at least partially extends from the opening to the outside of the power supply mechanism 100. At least one ridge 106 is configured to cooperate with the inner surface of the receiving cavity 102 at the opening to form a gap or clearance, and the gap or clearance is defined as the air inlet 241.

[0039] In some embodiments, the outer diameter of the atomizer 200 gradually decreases from the position where the opening of the power supply mechanism 100 at the first end 1011 is connected to the distal end 2012 and then remains constant, and at least one air groove extending in the longitudinal direction is arranged on the outer surface of the atomizer 200. That is, when the atomizer 200 is received in the receiving cavity 102, an air inlet channel 243 for air flow is formed or defined between the at least one air groove formed on the outer surface of the atomizer 200 and the inner surface of the receiving cavity 102. It can be obtained that the air inlet channel 243 gradually increases from the end close to the air inlet 241 and then remains constant as it gradually approaches the bracket 103.

[0040] In other embodiments, the inner diameter of the receiving chamber 102 gradually increases from the opening at the first end 1011 toward the inner bottom wall and then remains constant, and at least one air groove extending in the longitudinal direction is arranged on the inner surface of the receiving chamber 102. That is, when the atomizer 200 is received in the receiving chamber 102, an air inlet channel 243 for air flow is formed or defined between the at least one air groove formed on the inner surface of the receiving chamber 102 and the outer surface of the atomizer 200. It can be obtained that the air inlet channel 243 gradually increases from the end close to the air inlet port 241 and then remains constant as it gradually approaches the bracket 103.

[0041] like Figure 7 and Figure 8 As shown, a first electrode plug hole 129 is provided at the top of the bracket 103, and a first conductive electrode 105 is correspondingly inserted into the first electrode plug hole 129. One end of the first conductive electrode 105 is electrically connected to the control module through a wire. The first conductive electrode 105 protrudes from the top of the bracket 103. When the atomizer 200 is connected to the power supply mechanism 100, the other end of the first conductive electrode 105 protruding from the top of the bracket 103 contacts the second conductive electrode 235 provided on the end cover 231 of the atomizer 200, thereby making an electrical connection, so that the power supply mechanism 100 can provide electrical drive for the heating element 223.

[0042] In some embodiments, Figure 3 As shown, an airflow sensor 113 is also provided between the receiving cavity 102 and the second end 1012 of the power supply mechanism 100, for sensing the change of the airflow flowing through at least one air inlet channel 243 to control the working state of the power supply mechanism 100. Figure 7 As shown, the bracket 103 is provided with a fixing groove 114 for at least partially accommodating and retaining the airflow sensor 113. Optionally, the airflow sensor 113 is surrounded by a first sealing member 111. The airflow sensor 113 is electrically connected to the control module of the power supply mechanism 100 through a wire.

[0043] In some embodiments, an air guide cavity is enclosed between the end cap 231 at the bottom of the atomizer 200 and the top of the bracket 103, and the end of the air inlet channel 243 away from the air inlet 241 is connected to the air guide cavity. The air inlet channel 243 and the air guide cavity cooperate to enable air flow between the atomizer 200 and the power supply mechanism 100. The air flow sensor 113 has two air flow sensing ends arranged relatively along the radial direction of the power supply mechanism 100, one of which faces the battery cavity 123 and is connected to the air in the battery cavity, and the other air flow sensing end is a detection end, which is connected to the air guide cavity between the atomizer 200 and the power supply mechanism 100. When airflow enters the atomizer 200 through the air guide cavity from the air inlet channel 243, in response to the negative pressure generated in the air guide cavity, the air flow sensor 113 converts the air pressure change into an electrical signal and feeds it back to the control module inside the power supply mechanism 100, thereby generating an electrical drive to supply power to the atomizer 200.

[0044] like Figure 6 and Figure 8 As shown, a sensing connection port 239 is arranged on the top of the bracket 103, that is, the inner bottom wall of the receiving cavity 102. In some embodiments, a through sensing connection channel 125 is provided on the top of the bracket 103. Optionally, the sensing connection channel 125 can be a vent arranged on the top of the bracket 103. The sensing connection channel 125 extends from the airflow sensor 113 to the sensing connection port 239, thereby maintaining communication between the airflow sensor 113 and the sensing connection port 239. Further, an air groove 1111 is provided on the first sealing member 111 surrounding the airflow sensor 113, which is used to connect the airflow sensor 113 with the sensing connection channel 125. Specifically, the detection end of the airflow sensor 113 faces the first sealing member 111, and can maintain communication with the sensing connection port 239 through the air groove 1111, thereby detecting the airflow volume change in the air guide cavity. In other words, the airflow sensor 113 can be connected to the air of the air guide cavity through the sensing connection port 239, thereby being used to sense the airflow change from at least one air inlet channel 243 to the air guide cavity.

[0045] In some embodiments, the airflow sensor 113 is disposed offset from the longitudinal center axis of the power mechanism 100 .

[0046] In some embodiments, the atomizer 200 is detachably connected to the power supply mechanism 100, for example, a magnetic connection or a snap-on connection. It is understandable that the battery assembly, as the main part of the electronic atomization device, is configured to be continuously used, while the atomizer 200 is configured to be replaceable as needed. In the implementation scheme provided in the present application, a magnetic connection is adopted between the atomizer 200 and the power supply mechanism 100. Specifically, a second magnetic suction socket 127 is provided on the top of the bracket 103, and a second magnetic suction element 107 is correspondingly inserted in the second magnetic suction socket 127; a first magnetic suction socket 245 is provided on the end cover 231 of the atomizer 200, and a first magnetic suction element 233 is correspondingly inserted in the first magnetic suction socket 245. The first magnetic suction element 233 and the second magnetic suction element 107 can be magnetically attracted to each other, that is, the first magnetic suction element 233 and the second magnetic suction element 107 cooperate to keep the atomizer 200 and the power supply mechanism 100 fixedly connected.

[0047] Figure 6 A schematic diagram of an airflow path in the electronic atomization device is shown when the electronic atomization device is in use, that is, when the first blocking member 207 and the second blocking member 209 are removed. In the embodiment provided in the present application, the electronic atomization device includes an airflow channel having a first channel portion and a second channel portion that are interconnected, providing an airflow path R1 between the air inlet 241 and the air outlet 202 of the atomizer 200 for external air, that is, when the user inhales, the external air enters the atomizer 200 from the air inlet 241 and carries the aerosol generated by the atomization of the atomizer 200 and is led out of the air outlet 202. Among them, the first channel portion extends from the air inlet 241 to the bracket 103 along the longitudinal direction of the electronic atomization device, and the second channel portion is defined in the atomizer 200 and extends to the air outlet 202 of the atomizer 200. Specifically, the first channel portion includes an air inlet channel 243 formed or defined between the outer surface of the atomizer 200 and the inner surface of the receiving chamber 102, and the second channel portion includes an air vent 232 opened on the end cover 231 of the atomizer 200, and an air flow channel connected in the order of the atomizing chamber 237, the mist guide channel and the air outlet 202. The air inlet channel 243 between the atomizer 200 and the inner surface of the receiving chamber 102 and the air vent 232 of the atomizer 200 are both connected to the air guide cavity, that is, the air guide cavity is connected to the first channel portion and the second channel portion. In other words, the sensing connection port 239 is connected to the first channel portion and the second channel portion, and the air flow sensor 113 can sense the air flow changes in the air inlet channel 243 by sensing the connecting channel 125.

[0048] like Figure 6As shown, in the embodiment provided by the present application, the airflow path R1 does not exceed the range of the receiving cavity 102 in the longitudinal direction of the electronic atomization device, that is, the airflow channel from the air inlet 241 to the air outlet 202 avoids the battery cell 115 along the longitudinal direction of the power supply mechanism 100. It is understandable that the battery cell 115 usually produces trace heavy metal elements when working, and the airflow channel passing through the battery cell 115 will cause the aerosol provided to the user to carry trace heavy metal elements. The trace heavy metal elements will not only reduce the taste of the aerosol, but also cause harm to human health. The embodiment provided by the present application can effectively avoid the harmful substances generated by the battery cell 115 when working by limiting the airflow channel from the air inlet 241 to the air outlet 202 to avoid the battery cell 115 along the longitudinal direction of the power supply mechanism 100 for use by the user.

[0049] In the embodiment provided in the present application, when the atomizer 200 is received in the receiving cavity 102, the inner surface of the receiving cavity 102 defines at least one air inlet 241 between the open portion and the atomizer 200, and the air inlet 241 is positioned at the proximal end 2011 of the second shell 201 close to the atomizer 200. In other words, the air inlet 241 is close to the air outlet 202 in the longitudinal direction of the electronic atomization device, that is, it is located at the upper position of the electronic atomization device as a whole. It can be understood that when the air flow rate entering the electronic atomization device from the air inlet 241 is large, the user has a small suction resistance when using the electronic atomization device; when the air flow rate entering the electronic atomization device from the air inlet 241 is small, the user has a large suction resistance when using the electronic atomization device. By setting the air inlet 241 at the upper position of the electronic atomization device as a whole, the present application can effectively avoid the problem of the user covering the air inlet 241 with his hand when holding the electronic atomization device for use, resulting in a reduction in air flow and unsmooth suction. In some embodiments, maintaining normal exposure of the air inlet 241 can maintain the air intake volume of the air inlet 241 within a certain range, so that the pressure value range corresponding to the suction resistance is also correspondingly stabilized within the range of plus or minus 100PA, thereby providing the user with a stable and smooth suction experience.

[0050] In some embodiments, the second magnetic element 107 is used to magnetically attract the first magnetic element 233, thereby providing guidance during the process of receiving the atomizer 200 in the receiving chamber 102, so that the atomizer 200 can be received in the receiving chamber 102 from the opening according to a predetermined orientation. Further, when the atomizer 200 is received in the receiving chamber 102, the first magnetic element 233 and the second magnetic element 107 are magnetically attracted to prevent the atomizer 200 from rotating relative to the power supply mechanism 100, so as to maintain the connection according to the predetermined orientation.

[0051] Specifically, the atomizer 200 is received in the receiving chamber 102 in an orientation in which the sensing communication port 239 and the at least one air inlet channel 243 are substantially aligned along the longitudinal direction of the power supply mechanism 100. In some embodiments, the atomizer 200 is received in the receiving chamber 102 in an orientation in which the sensing communication port 239 and the at least one air inlet 241 are substantially aligned along the longitudinal direction of the power supply mechanism 100. In other embodiments, the atomizer 200 is received in the receiving chamber 102 in an orientation in which the sensing communication port 239 deviates from the center of the inner bottom wall of the receiving chamber 102 and is close to the at least one air inlet 241 along the predetermined orientation.

[0052] like Figure 5 and Figure 6 As shown, the air inlet 241 is formed by the outer surface of the atomizer 200 and the inner surface of the receiving chamber 102 at the open position. When the atomizer 200 is received in the receiving chamber 102 at different angles, the relative position between the air inlet 241 or the air inlet channel 243 and the sensing communication port 239 will change accordingly according to the different angles. It can be understood that the air inlet 241 or the air inlet channel 243 is basically aligned with the sensing communication port 239 along the longitudinal direction of the power supply mechanism 100, or the sensing communication port 239 is deviated from the center of the inner bottom wall of the receiving chamber 102 along a predetermined orientation and close to the air inlet channel 243, which can shorten the distance from the air entering the electronic atomization device from the air inlet 241 to the sensing communication port 239 when the user inhales, thereby enhancing the negative pressure value of the airflow channel in the electronic atomization device detected by the airflow sensor 113 through the sensing connection channel 125, so as to improve the detection sensitivity of the airflow sensor 113, so that the airflow sensor 113 can work normally when the user inhales.

[0053] Different from the prior art, the present application discloses an electronic atomization device including a power supply mechanism 100 and an atomizer 200. By receiving the atomizer 200 in the receiving chamber 102 of the power supply mechanism 100 in a predetermined orientation, the air inlet channel 243 and the sensing connection port 239 are basically aligned and arranged along the longitudinal direction of the power supply mechanism 100, or the sensing connection port 239 deviates from the center of the inner bottom wall of the receiving chamber 102 along the predetermined orientation and is close to the air inlet channel 243, thereby shortening the distance from the air along the air inlet channel 243 to the sensing connection port 239 in structure, enhancing the negative pressure value of the air inlet channel 243 detected by the airflow sensor 113 through the sensing connection channel 125, and thereby improving the detection sensitivity of the airflow sensor 113. Furthermore, the air inlet channel 243 is defined to avoid the battery cell 115 along the longitudinal direction of the power supply mechanism 100, which can effectively avoid the harmful substances generated by the battery cell 115 when it is working from being exported for use by the user, and the air inlet 241 of the air inlet channel 243 is positioned along the longitudinal direction of the power supply mechanism 100 close to the air outlet 202 of the atomizer 200, which can effectively avoid the problem of the user covering the air inlet 241 with his hand when holding the electronic atomization device for use, resulting in a reduction in air flow and causing the problem of unsmooth suction.
