Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and more particularly to an electronic atomization device. Background Technology

[0002] An electronic atomizing device is a product that can transform a liquid aerosol matrix into an aerosol through atomization and other means. When the user inhales, the aerosol flows with the airflow generated by the user's inhalation and flows out of the electronic atomizing device.

[0003] Currently, the atomizing component of electronic atomizing devices is typically housed in a storage chamber containing a liquid aerosol generating matrix. When the device operates, the temperature of the atomizing component and its surrounding area rises rapidly, causing the air pressure within the storage chamber to increase. When the air pressure in the storage chamber becomes too high, the liquid aerosol generating matrix is ​​squeezed out and directly enters the atomization channel through the atomizing component, where it is then inhaled by the user, negatively impacting the vaping experience. Utility Model Content

[0004] The purpose of this application is to provide an electronic atomizing device that aims to solve the technical problem of increased gas pressure in the liquid storage chamber.

[0005] To achieve the above objectives, the technical solution adopted in this application embodiment is: an electronic atomizing device for heating an aerosol generating matrix to generate an aerosol, the electronic atomizing device including an oil cup assembly and an atomizing assembly.

[0006] The oil cup assembly has a liquid storage chamber for storing a liquid aerosol generation matrix. The oil cup assembly also includes a pressure relief hole and a pressure relief valve housed within the pressure relief hole, the pressure relief hole connecting the liquid storage chamber to the outside. An atomizing assembly is disposed within and communicates with the liquid storage chamber. The atomizing assembly has an atomizing channel and is used to heat the aerosol generation matrix entering the atomizing assembly and generate aerosol within the atomizing channel. When the air pressure in the liquid storage chamber is greater than the air pressure in the atomizing channel, the pressure relief valve is positioned with a gap between it and the pressure relief hole. When the air pressure in the liquid storage chamber is less than the air pressure in the atomizing channel, the pressure relief valve blocks the pressure relief hole.

[0007] The beneficial effects of the electronic atomizing device provided in this application are as follows: When the gas pressure in the liquid storage chamber is greater than the gas pressure in the atomizing channel, the pressure relief valve and the pressure relief hole are spaced apart, allowing the liquid storage chamber to communicate with the outside through the pressure relief hole. This allows the gas in the liquid storage chamber to be discharged through the pressure relief hole, thereby reducing the gas pressure in the liquid storage chamber and preventing the liquid aerosol generation matrix in the liquid storage chamber from directly entering the atomizing channel through the atomizing component. When the gas pressure in the liquid storage chamber is less than the gas pressure in the atomizing channel, the pressure relief valve blocks the pressure relief hole. When the user inhales the electronic atomizing device of this application embodiment, the airflow in the atomizing channel is not affected, so as not to affect the airflow carrying the atomizing component to heat the aerosol generation matrix to generate aerosol, thereby not affecting the normal operation of the electronic atomizing device.

The stop hole is located on the side of the connecting hole facing the liquid storage chamber, and the connecting hole is located on the side of the stop hole away from the liquid storage chamber. The inner diameter of the stop hole is larger than the inner diameter of the connecting hole. The pressure relief valve includes a connecting portion and a stop portion and a sealing portion disposed at both ends of the connecting portion. The stop portion is received in the stop hole and forms a first gap with the inner wall of the stop hole. The connecting portion passes through the connecting hole and forms a second gap with the inner wall of the connecting hole. The first gap and the second gap are in communication with each other.

[0010] In some embodiments, in the distribution direction of the stop hole and the connecting hole, the length of the connecting portion is greater than the depth of the connecting hole.

[0011] In some embodiments, the length of the stop portion is less than the depth of the stop hole along the axial direction of the pressure relief hole, so that the stop portion can reciprocate within the stop hole; wherein the displacement of the stop portion within the stop hole is equal to the difference between the length of the connecting portion and the depth of the connecting hole.

[0012] In some embodiments, the pressure relief hole includes a stepped surface connecting the stop hole and the connecting hole, and the stepped surface is provided with an exhaust groove, which communicates the first gap and the second gap.

[0013] In some embodiments, the oil cup assembly further includes a third seal disposed on the side of the second seal opposite to the first seal, and the third seal and the second seal enclose a pressure relief cavity for containing the aerosol-generating matrix flowing out through the pressure relief hole.

[0014] In some embodiments, the oil cup assembly further includes a liquid suction element housed within the pressure relief chamber.

[0015] In some embodiments, the atomizing assembly includes an atomizing core, an air guide tube, and a fixing base; one end of the air guide tube passes through the air outlet, and the end of the air guide tube away from the first seal is connected to the atomizing core; one end of the fixing base passes through the air inlet, and the end of the fixing base away from the second seal is connected to the end of the atomizing core away from the air guide tube; the air guide tube, the atomizing core, and the fixing base are sequentially connected and arranged to form the atomizing channel.

[0016] In some embodiments, the atomizing core includes a fixed cylinder, a liquid guiding component, and a heating mesh; the heating mesh surrounds the inner wall of the fixed cylinder, and the liquid guiding component is disposed between the inner wall of the fixed cylinder and the heating mesh; the fixed cylinder is provided with a liquid inlet hole, and the liquid guiding component contacts the aerosol generation matrix in the liquid storage chamber through the liquid inlet hole.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0032] An electronic atomizing device is a product that can transform a liquid aerosol matrix into an aerosol through atomization and other means. When the user inhales, the aerosol flows with the airflow generated by the user's inhalation and flows out of the electronic atomizing device.

[0033] Currently, the atomizing component of electronic atomizing devices is typically housed in a storage chamber containing a liquid aerosol generating matrix. When the device operates, the temperature of the atomizing component and its surrounding area rises rapidly, causing the air pressure within the storage chamber to increase. When the air pressure in the storage chamber becomes too high, the liquid aerosol generating matrix is ​​squeezed out and directly enters the atomization channel through the atomizing component, where it is then inhaled by the user, negatively impacting the vaping experience.

[0034] In view of the above problems, this application provides an electronic atomizing device, which aims to solve the technical problem of increased gas pressure in the liquid storage chamber.

[0035] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0036] Please refer to Figure 1 , Figure 2 and Figure 4 This application provides an electronic atomizing device for heating an aerosol generating matrix to generate an aerosol. The electronic atomizing device includes an oil cup assembly 1 and an atomizing assembly 2.

[0037] The oil cup assembly 1 has a liquid storage chamber 11 for storing the liquid aerosol generation matrix. The oil cup assembly 1 also includes a pressure relief hole 141 and a pressure relief valve 15 housed within the pressure relief hole 141, which connects the liquid storage chamber 11 to the outside. An atomizing assembly 2 is disposed within and communicates with the liquid storage chamber 11. The atomizing assembly 2 has an atomizing channel 21 for heating the aerosol generation matrix entering the atomizing assembly 2 and generating aerosol within the atomizing channel 21. When the pressure in the liquid storage chamber 11 is greater than the pressure in the atomizing channel 21, the pressure relief valve 15 is positioned with a gap between it and the pressure relief hole 141. When the pressure in the liquid storage chamber 11 is less than the pressure in the atomizing channel 21, the pressure relief valve 15 blocks the pressure relief hole 141.

[0038] In the electronic atomizing device provided in this application, when the air pressure in the liquid storage chamber 11 is greater than the air pressure in the atomizing channel 21, the pressure relief valve 15 and the pressure relief hole 141 are spaced apart, allowing the liquid storage chamber 11 to communicate with the outside through the pressure relief hole 141. This allows the gas in the liquid storage chamber 11 to be discharged through the pressure relief hole 141, thereby reducing the air pressure in the liquid storage chamber 11 and preventing the liquid aerosol generating matrix in the liquid storage chamber 11 from directly entering the atomizing channel 21 through the atomizing component 2. When the air pressure in the liquid storage chamber 11 is less than the air pressure in the atomizing channel 21, the pressure relief valve 15 blocks the pressure relief hole 141. When the user inhales the electronic atomizing device of this application embodiment, the airflow in the atomizing channel 21 is not affected, so as not to affect the airflow carrying the aerosol generated by the heating of the aerosol generating matrix by the atomizing component 2, thereby not affecting the normal operation of the electronic atomizing device.

[0039] It should be noted that, please refer to Figure 2 In the initial state (when the electronic atomizing device is not working), the air pressure in the liquid storage chamber 11 is equal to the air pressure in the atomizing channel 21, and the air pressure in the liquid storage chamber 11 is equal to the external air pressure. Under the action of its own gravity and the gravity of the aerosol generation matrix in the liquid storage chamber 11, the pressure relief valve 15 moves to the lower part of the pressure relief hole 141, so that the pressure relief valve 15 and the pressure relief hole 141 are separated, so that the liquid storage chamber 11 is connected to the outside. When the electronic atomizing device is working normally (the air pressure in the liquid storage chamber 11 will not be too high), when the user inhales, the air pressure in the atomization channel 21 is greater than the air pressure in the liquid storage chamber 11. Furthermore, the air pressure in the liquid storage chamber 11 decreases due to the loss of the liquid aerosol generation matrix, making the air pressure in the liquid storage chamber 11 less than the external air pressure. This causes the pressure relief valve 15 to overcome its own gravity and the gravity of the aerosol generation matrix in the liquid storage chamber 11 under the action of the external air pressure and move relative to the pressure relief hole 141. The pressure relief valve 15 moves until it covers the opening of the pressure relief hole 141 facing the outside, thus sealing the pressure relief hole 141 and preventing it from affecting the normal operation of the electronic atomizing device. When the air pressure in the storage chamber 11 is too high, the air pressure in the storage chamber 11 is greater than the air pressure in the atomization channel 21, and the air pressure in the storage chamber 11 is greater than the external air pressure. Under the combined action of its own weight, the weight of the aerosol generating matrix in the storage chamber 11, and the air pressure in the storage chamber 11, the pressure relief valve 15 overcomes the external air pressure and moves to the lower part of the pressure relief hole 141, so that the pressure relief valve 15 and the pressure relief hole 141 are separated, so that the gas in the storage chamber 11 can be discharged from the storage chamber 11 through the pressure relief hole 141 to reduce the air pressure in the storage chamber 11, thereby preventing the liquid aerosol generating matrix in the storage chamber 11 from directly entering the atomization channel 21 through the atomization component 2.

[0040] Please refer to Figure 1In some embodiments, the oil cup assembly 1 includes a cup cylinder 12 and a first sealing member 13 and a second sealing member 14 disposed at both ends of the cup cylinder 12. The first sealing member 13, the cup cylinder 12, and the second sealing member 14 surround to form a liquid storage cavity 11. This arrangement makes the structure of each component of the oil cup assembly 1 relatively simple and the cost low, and also facilitates the assembly and disassembly of the oil cup assembly 1 and the atomizing assembly 2.

[0041] In the above embodiment, the second sealing member 14 is provided with an air inlet 142, and the first sealing member 13 is provided with an air outlet 131. Both the air inlet 142 and the air outlet 131 are connected to the airflow channel, and the pressure relief hole 141 is provided on the second sealing member 14. It should be noted that the liquid storage space of the oil cup assembly 1 is the area of ​​the liquid storage chamber 11 excluding the airflow channel.

[0042] In the above embodiment, one end of the atomizing component 2 is inserted into the air inlet 142, and the other end of the atomizing component 2 is inserted into the air outlet 131.

[0043] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the pressure relief hole 141 includes a stop hole 1411 and a connecting hole 1412 coaxially arranged. The stop hole 1411 is located on the side of the connecting hole 1412 facing the liquid storage chamber 11, and the connecting hole 1412 is located on the side of the stop hole 1411 away from the liquid storage chamber 11. The inner diameter of the stop hole 1411 is larger than the inner diameter of the connecting hole 1412.

[0044] The pressure relief valve 15 includes a connecting part 152 and a stop part 151 and a sealing part 153 disposed at both ends of the connecting part 152. The stop part 151 is received in the stop hole 1411 and forms a first gap 1413 with the inner wall of the stop hole 1411. The connecting part 152 passes through the connecting hole 1412 and forms a second gap 1414 with the inner wall of the connecting hole 1412. The first gap 1413 and the second gap 1414 are in communication with each other.

[0045] In the above embodiment, in the radial direction of the pressure relief hole 141, the stop portion 151 protrudes from the inner wall of the connecting hole 1412, so that when the stop portion 151 is located at the lowest point of the stop hole 1411, the stop portion 151 can abut against the stepped surface 1415 between the stop hole 1411 and the connecting hole 1412, thereby preventing the pressure relief valve 15 from disengaging from the pressure relief hole 141. In the radial direction of the pressure relief hole 141, the sealing portion 153 protrudes from the inner wall of the connecting hole 1412, so that when the pressure relief valve 15 blocks the pressure relief hole 141, the sealing portion 153 can abut against the end face around the orifice of the pressure relief hole 141 facing the outside, preventing the pressure relief valve 15 from entering the liquid storage chamber 11. Furthermore, the stop portion 151 and the sealing portion 153 cooperate to limit the movement path of the pressure relief valve 15.

[0046] Please refer to Figure 2 and Figure 3 In the above embodiment, when the stop part 151 abuts against the stepped surface 1415 between the stop hole 1411 and the connecting hole 1412, the sealing part 153 will not cover the opening of the connecting hole 1412 facing the outside, so that the second gap 1414 can communicate with the outside.

[0047] Please refer to Figure 2 and Figure 3 In the above embodiment, when the blocking part 153 covers the opening of the connecting hole 1412 facing the outside, the second gap 1414 will also be covered by the blocking part 153, so that the second gap 1414 is no longer connected to the outside.

[0048] Please refer to Figure 2 and Figure 3 In the above embodiment, when the gas pressure in the liquid storage chamber 11 is greater than the gas pressure in the atomizing channel 21, the gap setting between the pressure relief valve 15 and the pressure relief hole 141 means that the stop part 151 and the inner wall of the stop hole 1411 are separated by a first gap 1413, and the connecting part 152 and the inner wall of the connecting hole 1412 are separated by a second gap 1414. The first gap 1413 is always in communication with the liquid storage chamber 11, and the second gap 1414 is in communication with the outside. Because the first gap 1413 and the second gap 1414 are interconnected, the gas in the liquid storage chamber 11 can flow out of the liquid storage chamber 11 sequentially through the first gap 1413, the connection between the first gap 1413 and the second gap 1414, and the second gap 1414. Therefore, in this embodiment, when the air pressure in the liquid storage chamber 11 is greater than the air pressure in the atomization channel 21, the pressure relief valve 15 and the pressure relief hole 141 are spaced apart, so that the gas in the liquid storage chamber 11 can be discharged from the liquid storage chamber 11 through the pressure relief hole 141 to reduce the air pressure in the liquid storage chamber 11, thereby preventing the liquid aerosol generation matrix in the liquid storage chamber 11 from directly entering the atomization channel 21 through the atomization component 2.

[0049] Please refer to Figure 3 and Figure 4 In some embodiments, the length of the connecting portion 152 is greater than the depth of the connecting hole 1412 in the distribution direction of the stop hole 1411 and the connecting hole 1412.

[0050] By adopting the above technical solution, the connecting part 152 can move within the connecting hole 1412, so that the pressure relief valve 15 can move to the second gap 1414 to communicate with the outside, and the pressure relief valve 15 can also move to block the opening of the connecting hole 1412 facing the outside.

[0051] Please refer to Figure 2 and Figure 3In some embodiments, the length of the stop portion 151 is less than the depth of the stop hole 1411 along the axial direction of the pressure relief hole 141, so that the stop portion 151 can reciprocate within the stop hole 1411. The displacement of the stop portion 151 within the stop hole 1411 is equal to the difference between the length of the connecting portion 152 and the depth of the connecting hole 1412. This design ensures the reliability of the sealing portion 153 in sealing the connecting hole 1412.

[0052] Specifically, along the axial direction of the pressure relief hole 141, the length of the stop portion 151 is less than the depth of the stop hole 1411, ensuring the effective range of motion of the stop portion 151. Specifically, the effective range of motion of the stop portion 151 (i.e., the displacement of the stop portion 151 in the stop hole 1411) is equal to the difference between the depth of the stop hole 1411 and the length of the stop portion 151. Correspondingly, the displacement of the stop portion 151 in the stop hole 1411 is equal to the difference between the length of the connecting portion 152 and the depth of the connecting hole 1412. This ensures that when the displacement of the stop portion 151 in the stop hole 1411 is at its maximum, the sealing portion 152 can simply abut against the second seal 14 to seal the connecting hole 1412, thereby ensuring the reliability of the sealing portion 153 in sealing the connecting hole 1412.

[0053] Please refer to Figure 3 , Figure 5 and Figure 6 In some embodiments, the pressure relief hole 141 includes a stepped surface 1415 connecting the stop hole 1411 and the connecting hole 1412. The stepped surface 1415 is provided with an exhaust groove 1416, which connects the first gap 1413 and the second gap 1414.

[0054] In the above embodiment, when the pressure relief valve 15 moves to the second gap 1414 to communicate with the outside, the stop part 151 covers part of the slot of the exhaust groove 1416, and does not affect the communication between the slot of the exhaust groove 1416 and the first gap 1413.

[0055] It should be noted that when the gas is discharged from the storage chamber 11 through the pressure relief hole 141, a small portion of the aerosol generation matrix in the storage chamber 11 will also be discharged from the storage chamber 11 through the pressure relief hole 141.

[0056] For the above issues, please refer to... Figure 6 In some embodiments, the venting groove 1416 has a first groove wall 14161 and a second groove wall 14162 disposed opposite to each other, and the distance between the first groove wall 14161 and the second groove wall 14162 gradually increases in a direction away from the axis of the pressure relief hole 141.

[0057] By adopting the above technical solution, the width of the exhaust groove 1416 gradually decreases in the direction close to the pressure relief hole 141, so as to slow down the flow speed of the aerosol generation matrix, thereby preventing the aerosol generation matrix from being discharged from the liquid storage chamber 11 through the pressure relief hole 141.

[0058] Please refer to Figure 6 In some embodiments, multiple exhaust channels 1416 are provided, and the multiple exhaust channels 1416 are arranged circumferentially at intervals along the pressure relief hole 141 to facilitate exhaust.

[0059] In some embodiments, the exhaust trough 1416 is provided with a baffle, one of the first trough wall 14161 and the second trough wall 14162 is connected to the baffle, and the other of the first trough wall 14161 and the second trough wall 14162 is disposed opposite to the baffle.

[0060] By adopting the above technical solution, the baffle can block the flow of aerosol generation matrix, so as to prevent the aerosol generation matrix from being discharged from the liquid storage chamber 11 through the pressure relief hole 141.

[0061] In some embodiments, multiple baffles are provided, and multiple baffles are arranged sequentially at intervals in the extending direction of the exhaust groove 1416. On the projection plane perpendicular to the extending direction of the exhaust groove 1416, the orthographic projection portions of adjacent baffles overlap, so as to form a meandering exhaust channel in the exhaust groove 1416.

[0062] By adopting the above technical solution, the blocking effect of multiple baffles can be enhanced.

[0063] Please refer to Figure 2 In some embodiments, the oil cup assembly 1 further includes a third seal 16, which is disposed on the side of the second seal 14 away from the first seal 13. The third seal 16 and the second seal 14 form a pressure relief cavity 17, which is used to contain the aerosol generation matrix flowing out through the pressure relief hole 141.

[0064] By adopting the above technical solution, the pressure relief chamber 17 is used to contain the aerosol generation matrix flowing out through the pressure relief hole 141, which can prevent the aerosol generation matrix from flowing out of the oil cup assembly 1, so as to avoid the aerosol generation matrix flowing out of the electronic atomizing device and thus not adversely affecting the user experience of the electronic atomizing device.

[0065] In some embodiments, the oil cup assembly 1 further includes a liquid suction member, which is housed in the pressure relief chamber 17.

[0066] By adopting the above technical solution, the liquid suction component can adsorb the aerosol generation matrix flowing out through the pressure relief hole 141, so as to prevent the aerosol generation matrix from flowing.

[0067] Please refer to Figure 1 and Figure 7 In some embodiments, the atomizing assembly 2 includes an atomizing core 22, an air guide tube 23, and a mounting base 24. One end of the air guide tube 23 passes through the air outlet 131, and the end of the air guide tube 23 away from the first seal 13 communicates with the atomizing core 22. One end of the mounting base 24 passes through the air inlet 142, and the end of the mounting base 24 away from the second seal 14 communicates with the end of the atomizing core 22 away from the air guide tube 23. The air guide tube 23, the atomizing core 22, and the mounting base 24 are sequentially connected to form an airflow channel.

[0068] Please refer to Figure 7 In some embodiments, the atomizing core 22 includes a fixed cylinder 221, a liquid guiding component 222, and a heating mesh 223. The heating mesh 223 surrounds the inner wall of the fixed cylinder 221, and the liquid guiding component 222 is disposed between the inner wall of the fixed cylinder 221 and the heating mesh 223. The fixed cylinder 221 is provided with a liquid inlet hole, and the liquid guiding component 222 contacts the aerosol generation matrix in the liquid storage chamber 11 through the liquid inlet hole.

[0069] In the above embodiment, the liquid guide 222 contacts the aerosol generating matrix in the liquid storage chamber 11 through the liquid inlet hole, and the heating mesh 223 contacts the aerosol generating matrix through the liquid guide 222. This not only controls the supply rate of the aerosol generating matrix, but also controls the contact area between the heating mesh 223 and the aerosol generating matrix. This ensures that when the aerosol generating matrix in the liquid storage chamber 11 decreases, the entire area of ​​the heating mesh 223 can still contact the aerosol generating matrix through the liquid guide 222, thus avoiding the situation where some heating mesh 223 cannot contact the aerosol generating matrix and will dry-burn.

[0070] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
