[0041] An embodiment of the present application provides an electronic atomization device 100, which is used to atomize a liquid matrix to generate an inhalable aerosol, such as Figure 1 As shown, the electronic atomization device 100 includes a shell 10 and a bottom cover 20, which are connected to form an outer shell of the electronic atomization device 100. A nozzle 11 is formed on the shell 10, and a user can inhale aerosol by sucking at the nozzle 11.
[0042] like Figure 2As shown, the nozzle 11 includes a longitudinally extending tubular body 111, the tubular body 111 has an air inlet end and an air outlet end which are relatively arranged, the air inlet end is defined with an air inlet 1111 for supplying aerosol to enter the tubular body 111, and the air outlet end is defined with an air outlet hole 1112 for supplying aerosol to escape from the electronic atomization device 100, and the user can inhale the aerosol escaping from the air outlet hole 1112 when inhaling on the nozzle 11.
[0043] Please continue reading Figure 2 , and refer to Figure 3 and Figure 4 A liquid storage member 12 is provided in the shell 10, and the liquid storage member 12 is used to store a nebulizable liquid matrix. The liquid storage member 12 may include flexible fibers, such as cotton fibers, non-woven fabrics, glass fiber ropes, etc., or include porous materials with a microporous structure, such as porous ceramics, so that the liquid storage member 12 can store a nebulizable liquid matrix.
[0044] The liquid storage member 12 has a first end face 121 and a second end face 122 that are arranged opposite to each other in the longitudinal direction, and a first through hole 123 connecting the first end face 121 and the second end face 122. The first through hole 123 is provided with an atomization component 13 and an air guide tube 14. The atomization component 13 is used to atomize the liquid matrix to generate an aerosol. The air guide tube 14 connects the atomization component 13 and the tubular body 111, and further transmits the aerosol generated by the atomization of the atomization component 13 to the tubular body 111.
[0045] The atomization assembly 13 includes a liquid guide member 131 and a heating element 132. The liquid guide member 131 is formed with a second through hole 1311 that runs longitudinally therethrough, so that the liquid guide member 13 has an outer surface 1312 and an inner surface 1313. The heating element 132 is combined on the inner surface 1313. The outer surface 1312 contacts the liquid storage member 12 to absorb the liquid matrix in the liquid storage member 12, and transfers the liquid matrix to the heating element 132 on the inner surface 1313. The heating element 132 heats the liquid matrix to atomize it to generate an aerosol, and releases the aerosol into the second through hole 1311. That is, the second through hole 1311 is used as an atomization chamber to provide a release space for the aerosol.
[0046] The liquid guide member 131 can be made of flexible fibers, such as cotton fibers, non-woven fabrics, glass fiber ropes, etc., or made of porous materials with microporous structures, such as porous ceramics, so that the liquid guide member 131 can absorb the liquid matrix from the liquid storage member 12 and transfer the liquid to the inner surface 1313, and then transfer it to the heating element 132 for heating and atomization. The heating element 132 can be combined with the liquid guide member 131 by printing, deposition, sintering or physical assembly, or wrapped on the liquid guide member 131.
[0047] Please continue reading Figure 2The electronic atomization device 100 includes a battery cell 15 and a main board 16. A controller of the electronic atomization device 100 is disposed on the main board 16. The battery cell 15 and the atomization component 13 are electrically connected to the controller, so that the controller can control the battery cell 15 to provide the atomization component 13 with the electric energy required for heating and atomization. The battery cell 15 can be a rechargeable battery cell or a non-rechargeable battery cell.
[0048] In addition, an air inlet 21 is provided in the bottom cover 20 for external air to enter the electronic atomization device. When the user inhales on the nozzle 11, a negative pressure is generated inside the electronic atomization device 100, thereby prompting external air to enter the electronic atomization device 100 through the air inlet 21, and flow to the atomization component 13 through the internal air flow channel of the electronic atomization device 100, and then carry the aerosol generated by the atomization of the atomization component 13 through the air guide tube 14 to be transmitted to the tubular body 111, and then escape from the air outlet 1111 in the tubular body 111 for inhalation by the user.
[0049] like Figure 2 As shown, the electronic atomization device 100 further includes a sealing member 17 and a bracket 18. The sealing member 17 and the inner wall of the housing 10 define a liquid storage cavity, and elastically abuts against the inner wall of the housing 10 to seal the liquid storage cavity. The liquid storage member 12 is disposed in the liquid storage cavity, so that the sealing member 17 can prevent the liquid matrix from leaking from the liquid storage cavity. The sealing member 17 can be any one of silicone, rubber, or latex.
[0050] The bracket 18 extends in the electronic atomization device 100 in the radial direction, and the bracket 18 is arranged on the side of the sealing member 17 away from the liquid storage chamber to provide support for the sealing member 17, and then the bracket 18 and the inner wall of the shell 10 define a first receiving space 181, and define a second receiving space 182 with the inner wall of the bottom cover 20, that is, the bracket 18 divides the internal space of the electronic atomization device 100 into a first receiving space 181 and a second receiving space 182 distributed in the longitudinal direction, as shown in FIG. Figure 5 As shown, the liquid storage component 20, the sealing component 17 and the atomization component 13 are arranged in the first receiving space 181, while the battery cell 15 and the main board 16 are arranged in the second receiving space 182.
[0051] like Figure 2 As shown, a first vent hole 183 communicating with the air inlet hole 21 and the atomization chamber 1311 is disposed on the bracket 18 , and the first vent hole 183 guides external air entering the electronic atomization device 100 into the atomization chamber 1311 .
[0052] like Figure 6 , Figure 7 and Figure 8As shown, the sealing member 17 is formed with a liquid injection hole 172, and the liquid injection hole 172 is used to inject the liquid matrix into the liquid storage cavity and store it in the liquid storage member 12. The bracket 18 is also formed with a blocking portion 184 extending into the liquid injection hole 172, and the blocking portion 184 and the liquid injection hole 172 can be sealed by interference fit, so that the blocking portion 184 seals the liquid injection hole. When it is necessary to inject the liquid matrix into the liquid storage cavity, the blocking portion 184 can be removed from the liquid injection hole 172 first, and then the liquid matrix can be injected into the liquid storage cavity. After the injection is completed, the blocking portion 184 can be reinserted into the liquid injection hole 172.
[0053] And, in some embodiments, as Figure 7 and Figure 8 As shown, a plurality of injection holes 172 are provided, and a corresponding number of blocking portions 184 is also a plurality of the same number. The plurality of blocking portions 184 are provided around the first vent hole 183, so that when the liquid matrix is injected into the liquid storage cavity, the injection time can be shortened by providing the plurality of injection holes 172.
[0054] And, if Figure 2 and Figure 5 As shown, the bracket 18 is also formed with a first mounting groove 185, in which an airflow sensor 19 is mounted, the airflow sensor 19 is electrically connected to the control, and the airflow sensor 19 is in communication with the atomization chamber 1311. When the user inhales at the air outlet 1112, the atomization chamber 1311 generates a negative pressure, and the airflow sensor 19 senses the negative pressure and generates an electrical signal to send to the controller, and the controller can control the electronic atomization device 100 to start heating according to the electrical signal.
[0055] In summary, this embodiment provides a multifunctional bracket 18, that is, the sealing portion 184, the first mounting groove 185 for mounting the airflow sensor 19, and the first vent hole 183 for guiding external air into the atomization chamber 1311 are all arranged on the bracket 18, so there is no need to use other structural components to fix the airflow sensor 19 and the sealing portion 184, and there is no need to set air holes for guiding external air to the atomization chamber 1311 on other components. Therefore, the structural components of the electronic atomization device 100 can be reduced, thereby reducing the assembly steps accordingly, and further reducing the overall manufacturing cost of the electronic atomization device 100.
[0056] In some embodiments, Figure 2 and Figure 5As shown, a second mounting groove 186 is also formed on the bracket 18, and a liquid absorbent member 30 is installed in the second mounting groove 186. The liquid absorbent member 30 is provided with a through hole for the plugging portion to penetrate. When the electronic atomization device 100 is stored or transported, the air pressure in the liquid storage chamber is greater than the external air pressure, so that the liquid matrix may leak through the injection hole 172, and the liquid absorbent member 30 can absorb the leaked liquid matrix to prevent the liquid matrix from leaking out of the electronic atomization device 100. The liquid absorbent member 30 is made of a hygroscopic material, such as any one of cotton fiber, non-woven fabric, glass fiber rope, etc.
[0057] In some embodiments, Figure 2 and Fig. 9 As shown, the sealing member 17 includes a first surface 173 and a second surface 174 arranged opposite to each other, and a second vent hole 175 connecting the first surface 173 and the second surface 174, and the second vent hole 175 connects the first vent hole 183 and the atomization chamber 1311, thereby guiding the external air into the atomization chamber 1311. The sealing member 17, the liquid absorbing member 30 and the bracket 18 define an air channel 178 together, and the air channel 178 connects the air flow sensor 19 and the second vent hole 175, so that the air channel 178 can be used as an independent airway to trigger the air flow sensor 19, thereby improving the triggering sensitivity of the air flow sensor 19.
[0058] Specifically, Figure 8 As shown, a groove 176 communicating with the second vent hole 175 is provided on the second surface 174 supported by the bracket 18, and the groove 176, the liquid absorbent member 30 and the bracket 18 define the above-mentioned air channel 178. Alternatively, in some embodiments, a groove may be provided on the liquid absorbent member 30 and the bracket 10, and the groove and the sealing member 17 define the above-mentioned air channel.
[0059] In some embodiments, Figure 2 As shown, the airflow sensor 19 and the inner wall of the first mounting groove 185 are interference fit, and sealing is achieved through interference between the airflow sensor 19 and the first mounting groove 185. There is no need to use additional seals to seal the airflow sensor 19, further reducing the manufacturing cost of the electronic atomization device 100.
[0060] In some embodiments, Figure 5As shown, the bracket 18 is provided with a through hole 187 connecting the first receiving space 181 and the second receiving space 182, and the through hole 187 and the first vent hole 183 are arranged at intervals to prevent the electrode lead 133 from directly passing through the first vent hole 183 and affecting the air flow entering the atomization chamber 133. Since the liquid storage part 12 and the atomization assembly 13 are located in the first receiving space 181, and the battery cell 15 and the main board 16 are located in the second receiving space 182, the atomization assembly 13 includes the electrode lead 133, so the electrode lead 133 can pass through the through hole 187 to be electrically connected to the main board 16, so that the controller controls the battery cell 15 to provide electrical energy to the atomization assembly 13 through the electrode lead 133.
[0061] And, in some embodiments, as Figure 2 and Figure 8 As shown, the second vent hole 175 is not only used to guide the external air into the atomizing chamber 1311, but also used for the electrode lead 133 to pass through, that is, the electrode lead 133 passes through the second vent hole 175 of the seal 17 and the through hole 187 of the bracket 18 in sequence to be electrically connected to the main board 16. A wire groove 177 is also provided on the second surface 174 of the seal 17, and the wire groove 177 connects the second vent hole 175 and the through hole 187. The electrode lead 133 passing through the second vent hole 175 can be accommodated in the wire groove 177 and extends into the through hole 187 along the wire groove 177, which facilitates the routing of the electrode lead 133.
[0062] It should be noted that, in some embodiments, the electronic atomization device 100 may not be provided with a liquid storage member 12 , and the liquid matrix is directly stored in the liquid storage chamber, and then the liquid guiding element 131 in the atomization component 13 directly absorbs the liquid matrix in the liquid storage chamber.
[0063] In some embodiments, Fig. 9 As shown, one side of the airflow sensor 19 has a pin 191 , and the side of the airflow sensor 19 with the pin is installed in the first installation groove 185 away from the liquid storage chamber, so that the pin 191 is exposed to the opening of the first installation groove 185 .
[0064] And, it should be noted that the electronic atomization device 100 may not include the battery core 15, and the electronic atomization device 100 may be powered by an external power supply assembly. Specifically, a conductive contact (not shown) may be provided on the electronic atomization device 100, and a power supply terminal (not shown) may be provided on the power supply assembly. The electronic atomization device 100 is connected to the external power supply assembly by a detachable connection method, such as a magnetic connection, a snap connection, etc. When the electronic atomization device 100 is connected to the external power supply assembly, the power supply terminal of the power supply assembly can be in contact with the conductive contact to achieve electrical connection, so that the power supply assembly can provide electrical energy to the electronic atomization device 100.
[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Under the concept of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present application as described above, which are not provided in detail for the sake of simplicity. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents.
