Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and particularly to an aerosol generating device. Background Art

[0002] The working principle of the aerosol generating device is as follows: when the user sucks air through the mouthpiece, the air pressure in the atomization chamber drops instantaneously. Since both the atomization chamber and the liquid storage chamber are connected to the liquid guiding channel, the atomization liquid is guided into the atomization chamber through the pressure difference between the liquid storage chamber and the atomization chamber for heating and atomization to generate aerosol gas.

[0003] However, in traditional aerosol generating devices such as Chinese Patent CN115067549A, simply guiding the liquid through the pressure difference between the liquid storage chamber and the atomization chamber has the problem of poor atomization controllability, making the aerosol generating device unable to flexibly adapt to the needs of users.

[0034] To better understand the technical solutions and beneficial effects of the present application, the following further details the present application with specific embodiments:

[0035] Such asFigures 1 to 3 As shown, an aerosol generating device 10 of an embodiment includes a power supply pump air seat 100, a housing 200, and an atomizing air outlet assembly 300. The power supply pump air seat 100 includes a power supply seat 110 and a pressure regulating mechanism 120. The power supply seat 110 is formed with an air inlet passage 102, and the pressure regulating mechanism 120 is disposed on the power supply seat 110. Also refer to Figure 4 and Figure 5 , the air inlet end 122 of the pressure regulating mechanism 120 is communicated with the air inlet passage 102, so that the air inlet end of the pressure regulating mechanism 120 sucks air through the air inlet passage 102. The housing 200 is sleeved on the power supply pump air seat 100; the atomizing air outlet assembly 300 is formed with a liquid storage cavity 302, a current passing hole 304, and an atomizing air outlet hole 306. Both the liquid storage cavity 302 and the current passing hole 304 are communicated with the atomizing air outlet hole 306. Also refer to Figure 6 , the air outlet end 124 of the pressure regulating mechanism 120 is communicated with the liquid storage cavity 302, so that the pressure regulating mechanism 120 can inflate the liquid storage cavity 302 to adjust the air pressure in the liquid storage cavity 302. The atomizing air outlet assembly 300 is sleeved on the housing 200, so that the housing 200 is respectively sleeved on the atomizing air outlet assembly 300 and the power supply pump air seat 100.

[0036] For the above-mentioned aerosol generating device 10, since the air inlet end of the pressure regulating mechanism 120 is communicated with the air inlet passage 102, and since both the liquid storage cavity 302 and the current passing hole 304 are communicated with the atomizing air outlet hole 306, and in addition, the air outlet end of the pressure regulating mechanism 120 is communicated with the liquid storage cavity 302, the pressure regulating mechanism 120 can regulate the pressure inside the liquid storage cavity 302, realize the regulation of the pressure in the liquid storage cavity 302, so that the pressure difference between the liquid storage cavity 302 and the atomizing air outlet hole 306 is regulated, and further the export volume flowing from the liquid storage cavity 302 into the atomizing air outlet hole 306 is regulated, improving the atomization reliability of the aerosol generating device 10, and further enabling the aerosol generating device 10 to flexibly adapt to the needs of users.

[0037] As Figure 3 and Figure 4 shown, in one of the embodiments, the power supply seat 110 includes a seat body 112 and a power supply 114. A partition 113 is provided inside the seat body 112, so that the seat body 112 forms a first receiving cavity 112a and a second receiving cavity 112b. The first receiving cavity 112a is communicated with the air inlet passage 102. The power supply 114 is disposed in the first receiving cavity 112a, and the pressure regulating mechanism 120 is disposed in the second receiving cavity 112b, so that the power supply 114 and the pressure regulating mechanism 120 can be separately disposed in the seat body 112, avoiding the problem that the heat generated by the operation of the power supply 114 affects the heat generated by the operation of the pressure regulating mechanism 120, and improving the service life of the aerosol generating device 10.

[0038] AsFigure 4 and Figure 5 As shown in Figure 5 , in one embodiment, a microphone holder 112c is provided inside the base 112. The base 112 is provided with a vent hole 112d. A microphone 1122 is provided inside the microphone holder 112c. The microphone is provided with a trigger hole 1124. The trigger hole is communicated with the first receiving cavity 112a and the vent hole respectively. The vent hole is communicated with the flow hole 304, so that the air flow entering the first receiving cavity 112a flows into the vent hole through the trigger hole, and then flows into the flow hole 304 through the vent hole, realizing the start trigger of the aerosol generating device 10.

[0039] As Figure 5 shown in Figure 5 , in one embodiment, the base 112 is provided with a first air injection hole 101, and the atomizing air outlet assembly 300 is provided with a second air injection hole 302. The first air injection hole 101 is communicated with the second air injection hole 302. The air pressure regulating mechanism 120 is communicated with the liquid storage cavity 302 through the first air injection hole 101 and the second air injection hole 302 in sequence, so that the air outlet end of the air pressure regulating mechanism 120 is better communicated with the liquid storage cavity 302. In this embodiment, a connecting column 112d protrudes from one side of the base 112. The first air injection hole 101 is formed in the connecting column 112d. The air outlet end of the air pressure regulating mechanism 120 is sleeved on the connecting column 112d, and the air outlet end of the air pressure regulating mechanism 120 is communicated with the second air injection hole 302 through the first air injection hole 101.

[0040] As Figure 1 and Figure 2As shown, in one of the embodiments, at the end of the base 112 adjacent to the atomizing air outlet assembly 300, a first mounting boss 1121 and a second mounting boss 1124 are convexly provided. The first mounting boss 1121 is provided with a first through hole 1123, and the second mounting boss 1124 is provided with a second through hole 1125. The base 112 includes a first conductive spring pin 1127 and a second conductive spring pin 1128. The first conductive spring pin 1127 is inserted through the first through hole 1123, and the second conductive spring pin 1128 is inserted through the second through hole 1125. The first conductive spring pin 1127 is electrically connected to the positive electrode of the power supply 114, and the second conductive spring pin 1128 is electrically connected to the negative electrode of the power supply 114. Further, the atomizing air outlet assembly 300 abuts against the base 112. The atomizing air outlet assembly 300 includes an oil cup 310, a sealing seat 320, an atomizing core 330, and a conductive seat 340. The oil cup 310 is sleeved on the sealing seat 320 and the conductive seat 340 respectively, so that the oil cup 310 and the conductive seat 340 jointly enclose a liquid storage cavity 302. The current passing hole 304 and the atomizing air outlet hole 306 are both formed in the sealing seat 320. The atomizing core 330 is arranged in the atomizing air outlet hole 306. The conductive seat 340 is respectively provided with a first conductive column 342 and a second conductive column 344. The first conductive column 342 abuts against the first conductive spring pin 1127, and the second conductive column 344 abuts against the second conductive spring pin 1128. Both the first conductive column 342 and the second conductive column 344 are electrically connected to the atomizing core 330, so that the atomizing core 330 is electrically connected to the power supply 114. At the same time, the condensate on the surface of the base 112 is not easily introduced onto the surfaces of the first conductive spring pin 1127 or the second conductive spring pin 1128, avoiding the problem that the aerosol generating device is prone to short circuit.

[0041] As Figure 4 and Figure 5 shown, further, the conductive seat 340 forms a stepped column sleeve structure 343. The stepped column sleeve structure 343 includes a first cylindrical sleeve 343a and a second cylindrical sleeve 343b which are connected. The diameter of the first cylindrical sleeve 343a is larger than that of the second cylindrical sleeve 343b. The second air injection hole 302 includes a first empty groove 3022 formed in the first cylindrical sleeve 343a and an air injection through hole 3024 formed in the second cylindrical sleeve 343b. The first empty groove 3022 is respectively communicated with the air injection through hole 3024 and the first air injection hole 101, so that the second air injection hole 302 is communicated with the first air injection hole 101.

[0042] As Figure 4 and Figure 5As shown, further, a support convex column 112d protrudes from the other side of the seat body 112. The support convex column abuts against the sealing seat 320, and a second empty groove 1128 communicating with the first air injection hole 101 is formed in the support convex column 112d. The second empty groove communicates with the first empty groove 3022, so that the first air injection hole 101 communicates with the first empty groove 3022. Further, a part of the support convex column is located in the first empty groove 3022 and is connected to the sealing seat 320, so that the first air injection hole 101 and the first empty groove 3022 are better communicated.

[0043] As Figure 4 and Figure 5 As shown, further, the atomizing air outlet assembly 300 further includes a sealing column 350. Both ends of the sealing column 350 are respectively located in the first empty groove 3022 and the second empty groove 1128. A sealing through hole 352 is formed in the center of the sealing column 350. The sealing through hole 352 communicates with the air injection through hole 3024 and the first air injection hole 101 respectively, so that the sealing column 350 is tightly connected to the seat body and the sealing seat 320 respectively, avoiding air leakage between the seat body and the sealing seat 320, and further enabling the air injection through hole 3024 and the first air injection hole 101 to be reliably communicated. In this embodiment, the sealing column 350 is a silica gel column or a rubber column, so that the sealing column 350 has good elasticity. Further, the atomizing air outlet assembly 300 further includes a sealing ring 360. A positioning ring groove is formed at the position of the sealing column 350 corresponding to the first empty groove 3022. The sealing ring 360 is sleeved in the positioning ring groove, so that the sealing column 350 abuts more tightly against the sealing seat 320, thus better avoiding air leakage at the connection between the sealing column 350 and the sealing seat 320.

[0044] As Figure 4 and Figure 5 As shown, further, the atomizing air outlet assembly 300 further includes a one-way valve 370. The one-way valve 370 is arranged in the first empty groove 3022 and is tightly connected to the first cylindrical sleeve 343a. One end of the one-way valve 370 abuts against the inner wall of the first empty groove 3022, and the other end of the one-way valve 370 abuts against the sealing column 350, so that the one-way valve 370 is tightly arranged in the first empty groove 3022. In this embodiment, the air inlet end of the one-way valve 370 communicates with the sealing through hole 352, and the air outlet end of the one-way valve 370 communicates with the liquid storage cavity 302, so that the air flow in the sealing through hole 352 can inflate the liquid storage cavity 302 through the one-way valve 370, and the gas in the liquid storage cavity 302 cannot flow back or leak.

[0045] As Figure 4 and Figure 5As shown, further, a gas injection guide needle 3432 protrudes from one end of the second cylindrical sleeve 343b away from the first cylindrical sleeve 343a. The gas injection guide needle 3432 is located in the liquid storage cavity 302, and the end of the gas injection guide needle 3432 adjacent to the second cylindrical sleeve 343b is arranged adjacent to the top of the liquid storage cavity 302, so that the atomized liquid in the liquid storage cavity 302 is not easily in contact with the gas outlet end of the gas injection guide needle 3432, and even affects the gas outlet of the gas injection guide needle 3432. In this embodiment, the pore diameter of the gas injection guide needle 3432 is 0.5 mm to 1 mm, so that the pore diameter of the gas injection guide needle 3432 is relatively small. If the gas injection guide needle 3432 contacts the atomized liquid when the aerosol generating device 10 is tilted, the atomized liquid can only form a stable ink in the pores at the end of the gas injection guide needle 3432, avoiding the situation of the atomized liquid flowing back through the gas injection guide needle 3432.

[0046] Further, the gas outlet end of the air pressure regulating mechanism 120 is used to output gas, so that the air pressure in the liquid storage cavity 302 changes. It can be understood that the gas can be air or nitrogen gas or other harmless gases. In this embodiment, the gas is nitrogen gas, which avoids problems such as oxidation of the atomized liquid caused by the gas filled into the liquid storage cavity 302, and prolongs the service life of the aerosol generating device.

[0047] To precisely control the air pressure in the liquid storage chamber 302, further, the control method of the aerosol generating device 10 includes: First, detecting the air pressure in the liquid storage chamber 302 to obtain the current air pressure value in the liquid storage chamber 302; then obtaining the target gear instruction for the atomization concentration of the atomizing gas; then retrieving the target air pressure value in the liquid storage chamber 302 according to the target gear instruction; then taking the difference between the target air pressure value and the current air pressure value to obtain the air pressure difference; then calculating the air injection volume of the air pressure regulating mechanism 120 according to the air pressure difference; then controlling the air pressure regulating mechanism 120 to inject air into the liquid storage chamber 302 to precisely control the air pressure value injected into the liquid storage chamber 302, so as to effectively adjust the pressure difference between the liquid storage chamber 302 and the atomizing air outlet 306, and thus effectively adjust the export volume flowing from the liquid storage chamber 302 into the atomizing air outlet 306. In this embodiment, the target gear instruction is generated by the user through pressing input, parameter setting input, or wireless control input according to the usage needs. Further, the target air pressure value can be obtained by calculation according to the target gear instruction. Further, the step of obtaining the target air pressure value in the liquid storage chamber 302 by calculation according to the target gear instruction is specifically: According to the target gear instruction, performing an operation through the conversion algorithm between the gear and the air pressure value to obtain the target air pressure value in the liquid storage chamber 302. In this embodiment, the gear is the concentration value of the aerosol gas, and the aerosol gas is in a direct proportion relationship with the exported atomized liquid volume during the heating process, that is, the larger the exported atomized liquid volume, the higher the concentration of the aerosol gas generated during the heating process. Further, before the step of detecting the air pressure in the liquid storage chamber 302, the control method further includes: establishing a database in which multiple target gear instructions and multiple target air pressure values are in one-to-one correspondence, so as to retrieve the target air pressure value in the liquid storage chamber 302 according to the target gear instruction subsequently, improving the convenience and applicability of the aerosol generating device 10.

[0048] Further, the step of detecting the air pressure in the liquid storage chamber 302 is specifically: Detecting the air pressure in the liquid storage chamber 302 through a pressure sensor. The pressure sensor is arranged on the base body, and a part of the pressure sensor is located in the liquid storage chamber 302, so that the pressure sensor can detect the air pressure in the liquid storage chamber 302, thus better adjusting the air pump pressure according to the pressure in the oil cup 310, so as to control the pressure in the liquid storage chamber 302 and the oil output size.

[0049] It can be understood that since the end of the base body 112 adjacent to the atomizing air outlet assembly 300 is convexly provided with a first mounting boss 1121 and a second mounting boss 1124, the first mounting boss 1121 is provided with a first through hole 1123, the second mounting boss 1124 is provided with a second through hole 1125, and the base body 112 is provided with a first air injection hole 101, the structural strength of the base body 112 is poor, such as Figure 3As shown, further, the microphone holder 112c is also connected to the partition plate 113, so that the partition plate 113 is more firmly arranged in the seat body 112. Compared with the conventional setting method in which the microphone holder 112c is arranged below the power supply 114, the setting method of the microphone holder 112c of the aerosol generating device 10 of the present application is more flexible, and at the same time, the seat body 112 has better structural strength. In this embodiment, the partition plate 113 is provided with a fixing groove, and the outer peripheral wall of the microphone holder 112c is located in the fixing groove and is connected to the partition plate 113. Specifically, the microphone holder 112c is fixedly connected to the partition plate 113 by gluing or welding, so that the microphone holder 112c is firmly connected to the partition plate 113. Further, a reinforcing rib is provided at the connection between the microphone holder 112c and the partition plate 113, so that the connection between the microphone holder 112c and the partition plate 113 has better structural strength.

[0050] As Figure 2 shown, in one embodiment, the conductive seat 340 is provided with a support boss 346, and the support boss 346 is connected to the sealing seat 320, so that the sealing seat 320 is relatively fixedly connected to the conductive seat 340, and at the same time, both the sealing seat 320 and the conductive seat 340 can be better assembled and connected in the oil cup 310. In one embodiment, the sealing seat 320 is provided with a fixing hole 327, and the support boss 346 is provided with a tapered convex column, and the tapered convex column is located in the fixing hole and is fixedly connected to the sealing seat 320, so that the sealing seat 320 is limited and fixedly connected to the support boss 346.

[0051] As Figure 3 shown, in one embodiment, the oil cup 310 includes an oil cup body 312 and a fixing sleeve 314. The oil cup body 312 is convexly provided with a connecting convex tube 312e. The oil cup body 312 is respectively sleeved on the sealing seat 320 and the conductive seat 340. The fixing sleeve 314 is sleeved on the connecting convex tube 312e. The sealing seat 320 is convexly provided with a sealing sleeve 321. The sealing sleeve 321 is respectively sleeved on the atomization core 330 and the fixing sleeve 314, so that the sealing sleeve 321 is hermetically connected to the atomization core 330 and the fixing sleeve 314 respectively, and the fixing sleeve 314 abuts against the atomization core 330. The sealing seat 320 is provided with a liquid inlet hole 306, and the liquid inlet hole 306 is arranged corresponding to the side wall of the atomization core 330; an atomization air outlet hole 306 is formed in the sealing seat 320.

[0052] In one embodiment, the fixing sleeve 314 is a rubber sleeve or a silicone sleeve, and the diameter of the fixing sleeve 314 is smaller than the outer diameter of the sealing sleeve 321, so that the sealing sleeve 321 is sleeved on the fixing sleeve 314. In this embodiment, the fixing sleeve 314 and the sealing sleeve 321 are in interference fit, so that the fixing sleeve 314 and the sealing sleeve 321 are tightly sleeved.

[0053] As Figure 3As shown, in one embodiment, the seat body 112 is formed with a liquid-blocking boss 1125. The liquid-blocking boss 1125 is arranged around the air passing hole, avoiding the problem that the condensate on the side of the seat body 112 adjacent to the atomizing air outlet assembly 300 easily flows into the power seat 110 or the surface of the air pressure regulating mechanism 120 through the air passing hole, and improving the service life of the aerosol generating device 10.

[0054] Compared with the prior art, the present invention has at least the following advantages:

[0055] In the above aerosol generating device, since the air inlet end of the air pressure regulating mechanism is communicated with the air inlet passage, and since the liquid storage cavity and the flow-through hole are both communicated with the atomizing air outlet hole, and in addition, the air outlet end of the air pressure regulating mechanism is communicated with the liquid storage cavity, the air pressure regulating mechanism can regulate the pressure in the liquid storage cavity, realizing the regulation of the pressure in the liquid storage cavity. In this way, the pressure difference between the liquid storage cavity and the atomizing air outlet hole is regulated, and further the outflow amount flowing from the liquid storage cavity into the atomizing air outlet hole is regulated, improving the atomization reliability of the aerosol generating device, and further enabling the aerosol generating device to flexibly adapt to the needs of users.

[0056] The above embodiments only represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
