Description

TECHNICAL FIELD

[0002] The atomization device refers to a device for forming aerosol by heating or ultrasonic method on the basis of stored atomizable medium. The atomization device usually comprises an atomizer and a power supply assembly. The atomizer is used for heating an atomization substrate to generate aerosol. The aerosol is mixed with air entering the atomizer and then flows out for a user to inhale. The power supply assembly is electrically connected with the atomizer to supply power for the atomizer. The atomizer with oil core separation can completely isolate the atomized liquid from the outside world in a closed space, which can greatly reduce the attenuation of the atomized liquid composition, so that the preserved taste is better and the effective preservation time is longer. Since the oil core is separated, the atomized liquid needs a certain time to soak the atomization assembly when activated, and the soaking speed of the atomized liquid to the atomization assembly is relatively slow and the soaking is not sufficient, which causes dry burning of the atomization assembly, so that the user will have a paste taste and an odor when inhaling.

[0044] The embodiments of the present application provide an atomizer 10, such as Figures 1 to 4 The atomizer 10 includes a housing 110, a liquid storage bin 120, and an atomization assembly 130. The liquid storage bin 120 is arranged in the housing 110, and the liquid storage bin 120 is provided with a liquid storage cavity 1201 for storing an atomization substrate. The atomization assembly 130 is arranged in the liquid storage bin 120, and the atomization assembly 130 is provided with a liquid inlet hole 1301. The atomization assembly 130 is configured to have a blocking state and a communication state relative to the liquid storage bin 120. Specifically, the atomization assembly 130 can be moved from a blocking position to a communication position relative to the liquid storage bin 120, so that the liquid inlet hole 1301 and the liquid storage cavity 1201 are switched from blocking to communication. A pressure cavity 140 is formed between the housing 110 and the liquid storage bin 120. When the atomization assembly 130 is in the communication state, the liquid storage bin 120 is configured to be movable relative to the housing 110 to increase the pressure of the pressure cavity 140 and pressurize the inside of the liquid storage cavity 1201, thereby driving the atomization substrate to move towards the liquid inlet hole 1301.

[0045] Specifically, in a long time without use or during transportation, the atomization assembly 130 can be located in the partition position, so that the liquid inlet hole 1301 is partitioned from the liquid storage cavity 1201, and the atomization liquid in the liquid storage cavity 1201 cannot enter the atomization assembly 130, so as to reduce the attenuation of the composition of the atomization liquid; when the atomizer 10 needs to be used, the atomization assembly 130 can be located in the communication position, so that the liquid inlet hole 1301 is communicated with the liquid storage cavity 1201, and the atomization liquid in the liquid storage cavity 1201 can enter the atomization assembly 130, at this time, the pressure cavity 140 can pressurize the liquid storage cavity 1201, so that the atomization liquid in the liquid storage cavity 1201 rapidly enters the atomization assembly 130 under the action of pressure, so that the atomization assembly 130 can be fully infiltrated in a short time, thereby reducing the user waiting time and improving the atomization effect.

[0046] In some embodiments, the shell 110 is provided with a containing groove 1106, and the liquid storage bin 120 is slidably arranged in the containing groove 1106, and the outer circumferential surface of the liquid storage bin 120 is sealingly connected with the groove wall of the containing groove 1106, and the side of the liquid storage bin 120 away from the liquid storage cavity 1201 and the groove wall of the containing groove 1106 jointly define the pressure cavity 140.

[0047] In some embodiments, as shown in Figure 11 and Figure 12 , the shell 110 is provided with a first opening 1105, the liquid storage bin 120 is provided with a second opening 1206, the liquid storage bin 120 can be inserted into the shell 110 through the first opening 1105, the atomization assembly 130 can be inserted into the liquid storage bin 120 through the second opening 1206, and the end of the shell 110 away from the first opening 1105 is provided with a first wall 113, and the end of the liquid storage bin 120 away from the second opening 1206 is provided with a second wall 123. The pressure cavity 140 can be composed of the first wall 113, the second wall 123 and the side wall of the shell 110 connected between the first wall 113 and the second wall 123.

[0048] In some embodiments, as shown in Figure 5 , the liquid storage bin 120 is provided with a pressure guide portion 124 at one end facing the pressure cavity 140, and the pressure guide portion 124 is used to transmit the pressure of the pressure cavity 140 to the liquid storage cavity 1201.

[0049] In some embodiments, as shown in Figure 4 and Figure 5 , the liquid storage bin 120 is configured to be movable relative to the shell 110 from a first pressure position to a second pressure position, so as to compress the volume of the pressure cavity 140, so that the gas in the pressure cavity 140 forms compressed gas, and the pressure guide portion 124 includes a pressure guide hole 1202, which is used to communicate the space in the pressure cavity 140 and the liquid storage cavity 1201, so that the compressed gas in the pressure cavity 140 enters the liquid storage cavity 1201, thereby increasing the pressure in the liquid storage cavity 1201.

[0050] Specifically, the liquid storage bin 120 can move along the length direction of the shell 110, so that the second wall 123 approaches the first wall 113 to compress the volume of the pressure cavity 140. Before use, the liquid storage bin 120 can be located at a first pressure position, at which the first wall 113 and the second wall 123 have a certain distance, the pressure cavity 140 has a certain volume, and the air pressure in the pressure cavity 140 and the air pressure in the liquid storage cavity 1201 can be the same as the atmospheric pressure. When in use, the liquid storage bin 120 can be moved from the first pressure position to a second pressure position under the action of external force, at which the distance between the first wall 113 and the second wall 123 is reduced, the volume of the pressure cavity 140 is correspondingly reduced, the air pressure in the pressure cavity 140 is increased, and the compressed gas can enter the liquid storage cavity 1201 through the pressure guide hole 1202 to increase the pressure in the liquid storage cavity 1201.

[0051] In some embodiments, the space size of the pressure cavity 140 can be adjusted according to the effect of the atomized liquid on the atomization assembly 130 to reach a balanced value. For example, when it is necessary to further accelerate the infiltration rate of the atomized liquid, the space of the pressure cavity 140 can be increased so that more gas can be compressed to generate greater pressure.

[0052] In some embodiments, the pressure guide hole 1202 can be provided on the second wall 123, and the second wall 123 can abut against the first wall 113 when the liquid storage bin 120 is located at the second pressure position, at which the volume of the pressure cavity 140 is approximately zero, and the compressed gas is entirely in the liquid storage cavity 1201.

[0053] In some embodiments, as shown in FIG. 2, the pressure guide hole 1202 can be provided on the first wall 113. Figure 7As shown, the pressure guiding part 124 includes a blocking member 160 and a pressure guiding hole 1202, the blocking member 160 is configured to block the pressure guiding hole 1202 when the liquid storage bin 120 is at the first pressure position, and the blocking member 160 is further configured to be separated from the pressure guiding hole 1202 under the pressure of the pressure cavity 140 when the liquid storage bin 120 moves from the first pressure position to the second pressure position, so that the pressure of the pressure cavity 140 is transmitted to the liquid storage cavity 1201 through the pressure guiding hole 1202. The blocking member 160 can be blocked in the pressure guiding hole 1202 when the atomizer 10 is not used, so as to separate the liquid storage cavity 1201 and the space in the pressure cavity 140, so as to prevent the atomized liquid in the liquid storage cavity 1201 from entering the pressure cavity 140 and leaking from the connection between the shell 110 and the liquid storage bin 120. During the movement of the liquid storage bin 120 from the first pressure position to the second pressure position, the volume of the pressure cavity 140 is compressed, the internal gas pressure gradually increases, the blocking member 160 is separated from the pressure guiding hole 1202 under the pressure of the compressed gas, and falls into the liquid storage cavity 1201, so that the space in the pressure cavity 140 and the liquid storage cavity 1201 are communicated, and the compressed gas can enter the liquid storage cavity 1201 to increase the pressure in the liquid storage cavity 1201.

[0054] In some embodiments, before the atomizer 10 is used, the liquid storage cavity 1201 can be filled with atomized liquid, and the blocking member 160 blocks the pressure guiding hole 1202, so that the liquid storage cavity 1201 is in a completely sealed state.

[0055] Specifically, the material of the blocking member 160 can be an elastic plastic or rubber material, such as silicone, nitrile rubber, or natural rubber.

[0056] In some other embodiments, the blocking member 160 can also not be provided, so that the liquid storage cavity 1201 is always in a communicated state with the space in the pressure cavity 140 through the pressure guiding hole 1202. When the liquid storage bin 120 moves from the first pressure position to the second pressure position, the gas in the liquid storage cavity 1201 and the space in the pressure cavity 140 is compressed synchronously, so that the pressure in the liquid storage cavity 1201 increases.

[0057] In some embodiments, as shown, Figure 10 The at least part of the side of the liquid storage bin 120 facing the pressure cavity 140 has a flexible structure 125, the flexible structure 125 forms the pressure guiding part 124, and the flexible structure 125 is configured to be deformed towards the side of the liquid storage cavity 1201 under the pressure of the pressure cavity 140, so as to compress the size of the space in the liquid storage cavity 1201.

[0058] Specifically, the flexible structure 125 can expand towards the side of the liquid storage cavity 1201 under the pressure of the pressure cavity 140, so as to compress the space in the liquid storage cavity 1201. The material of the flexible structure 125 can be an elastic rubber or plastic material.

[0059] In some embodiments, referring to Figures 4 to 9 , the atomization assembly 130 is further configured to move relative to the housing 110 from the first position to the second position while moving relative to the liquid storage bin 120 from the blocking position to the connecting position; the atomization assembly 130 is further configured to be movable relative to the housing 110 from the second position to the third position to drive the liquid storage bin 120 to move relative to the housing 110 from the first pressure position to the second pressure position.

[0060] Specifically, the atomization assembly 130 can be in sliding connection with the liquid storage bin 120 and the housing 110 respectively, the first position, the second position and the third position gradually approach the first wall 113 along the length direction of the housing 110, and the blocking position and the connecting position gradually approach the second wall 123 along the length direction of the liquid storage bin 120. Under the action of an external force, when the atomization assembly 130 slides relative to the housing 110 from the first position to the second position, the liquid storage bin 120 and the housing 110 are relatively fixed due to the friction therebetween, that is, the atomization assembly 130 slides relative to the housing 110 while also sliding relative to the liquid storage bin 120 from the blocking position to the connecting position; when the atomization assembly 130 continues to slide relative to the housing 110 from the second position to the third position, the atomization assembly 130 abuts against the liquid storage bin 120, the atomization assembly 130 and the liquid storage bin 120 are relatively fixed, and the liquid storage bin 120 is movable relative to the housing 110 from the first pressure position to the second pressure position under the driving of the atomization assembly 130.

[0062] Specifically, the blocking buckle 1203 and the connecting buckle 1204 can be provided at one end of the liquid storage bin 120 close to the second opening 1206, the blocking buckle 1203 and the connecting buckle 1204 can be through holes or grooves provided on the side wall of the liquid storage bin 120, the second clamping portion 1311 can be protruded from the outer periphery of the atomization assembly 130, the second clamping portion 1311 can have a shape of a circle, an arc or a triangle, and the side of the second clamping portion 1311 facing the second wall 123 can be an inclined surface or an arc surface, so that the second clamping portion 1311 can slide away from the blocking buckle 1203 under the action of an external force.

Specifically, the sleeve portion 1313 is provided with a receiving groove 1303, and one end of the atomizing core 132 is installed in the receiving groove 1303.

[0079] In some embodiments, a first sealing member 150 is provided between the liquid storage chamber 120 and the atomizing core 132. The first sealing member 150 seals between the inner peripheral surface of the liquid storage chamber 120 and the outer peripheral surface of the atomizing core 132, and forms a liquid storage cavity 1201 with the liquid storage chamber 120 and the atomizing core 132. A liquid inlet 1301 is provided on the atomizing core 132, and the liquid inlet 1301 is configured to be closed by the first sealing member 150 when the atomizing assembly 130 is in the partition position.

[0080] In some embodiments, the base 131 is slidably disposed within the housing 110 along the length of the housing 110 to move the atomizing assembly 130 between a first position, a second position, and a third position. When the atomizing assembly 130 is in the first position, the first seal 150 closes the liquid inlet 1301 to isolate the interior of the atomizing core 132 from the liquid storage chamber 120; when the atomizing assembly 130 is in the second position, the atomizing core 132 moves relative to the first seal 150 until the liquid inlet 1301 is outside the first seal 150, so that the liquid inlet 1301 connects the interior of the atomizing core 132 with the liquid storage chamber 120.

[0081] Specifically, when the second latching part 1311 is located at the first latching position 1101, the first sealing member 150 closes the liquid inlet hole 1301 to isolate the interior of the atomizing core 132 from the liquid storage chamber 120; when the second latching part 1311 moves from the first latching position 1101 to the second latching position 1102, the base 131 is configured to drive the atomizing core 132 to move relative to the first sealing member 150 so that the liquid inlet hole 1301 connects the interior of the atomizing core 132 with the liquid storage chamber 120.

[0082] In some embodiments, the atomization core 132 includes an atomization tube 1321, a liquid guide 1322, a heating element 1323, and a mounting tube 1324. The liquid storage cavity 1201 is formed between the atomization tube 1321 and the liquid storage compartment 120. The liquid inlet hole 1301 is formed on the atomization tube 1321. The mounting tube 1324 is arranged in the atomization tube 1321. The liquid guide 1322 is arranged in the mounting tube 1324. The heating element 1323 is wrapped in the liquid guide 1322. The liquid guide 1322 is used to guide the atomization liquid to the heating element 1323, so that the atomization liquid is heated and atomized to form an aerosol. The aerosol can move along the atomization tube 1321 to the outside of the atomizer 10.

[0083] In some embodiments, an external force can act on the base 131 to push the atomization core 132 towards the pressure cavity 140, so that the liquid inlet hole 1301 is exposed to the first sealing element 150 and enters the liquid storage cavity 1201. The liquid storage cavity 1201 is in communication with the liquid inlet hole 1301 and the micropores of the liquid guide 1322 and the external atmosphere. The atomization liquid in the liquid storage cavity 1201 can enter the atomization core 132 through the liquid inlet hole 1301. At this time, the blocking element 160 is still located at the pressure guide hole 1202. The continued application of the external force to press the base 131 can move the liquid storage compartment 120 relative to the shell 110 from the first pressure position to the second pressure position. Because the gas in the pressure cavity 140 is compressed to form compressed air with a certain pressure during the pressing process, when the pressure reaches a certain range, the compressed air will push the blocking element 160 in the pressure guide hole 1202 out into the liquid storage cavity 1201, so that the compressed gas in the pressure cavity 140 is pushed into the liquid storage cavity 1201, thereby causing the pressure in the liquid storage cavity 1201 to increase. The atomization liquid in the liquid storage cavity 1201 rapidly enters the liquid guide 1322 under the action of the pressure, thereby accelerating the speed of soaking and making the soaking more sufficient, achieving the effect of soaking and inhaling at the same time, allowing the user to not need to wait for a period of time, and increasing the experience effect.

[0084] In some embodiments, the first sealing element 150 is provided with a reinforcing element 170 on the side facing the liquid storage cavity 1201. The reinforcing element 170 and the first sealing element 150 are fixedly connected in the liquid storage compartment 120. Specifically, the reinforcing element 170 and the first sealing element 150 can be fixed at the step in the liquid storage compartment 120. The reinforcing element 170 can enhance the fixed relationship between the first sealing element 150 and the liquid storage compartment 120, and avoid the movement of the first sealing element 150 under the action of the pressure inside the liquid storage cavity 1201.

[0085] In some embodiments, the material of the atomization tube 1321 and the mounting tube 1324 can be hard plastic or metal material, such as stainless steel, high-transparency copolyester material, or the like.

The material of the first sealing element 150 can be elastic plastic or rubber material, such as silicone, nitrile rubber, or natural rubber, or the like. The material of the reinforcing element 170 can be corrosion-resistant hard metal or plastic, such as stainless steel or nickel alloy, or the like.

[0086] In some embodiments, the base 131 is provided with a liquid suction element 133 close to one end of the liquid storage cavity 1201, and is provided with an electrode element 134 away from the other end of the liquid storage cavity 1201. The electrode element 134 is electrically connected to the heating element 1323, and the external power supply assembly 20 can supply power to the heating element 1323 through the electrode element 134. The liquid suction element 133 is used to absorb the atomization liquid and condensed water leaking from the atomization core 132, so as to avoid corrosion of the electrode element 134 and other electrical connection structures by the atomization liquid and the condensed water. The material of the liquid suction element 133 can be a material having the function of adsorbing liquid, for example, the liquid suction element 133 can be liquid absorbing cotton.

[0087] In some embodiments, as shown in Figure 2 , the base 131 can be provided with an air inlet hole, and external air can enter the atomization tube 1321 through the air inlet hole. The end of the base 131 away from the liquid storage cavity 1201 can be provided with a groove. When the electrode element 134 is electrically connected to the power supply assembly 20, the groove can play a guiding and positioning role. At the same time, the groove can reduce the overall weight of the atomizer 10. In addition, the groove can cooperate with the electrode element 134 to form a symmetrical pattern around the air inlet hole, so as to improve the aesthetic appearance.

[0088] In some embodiments, as shown in Figure 4 , Figure 11 , and Figure 12 , the shell 110 includes a first main body part 111 and a first air outlet tube 112 connected to each other, and the liquid storage compartment 120 includes a second main body part 121 and a second air outlet tube 122 connected to each other.

The side of the second main body part 121 away from the liquid storage cavity 1201, the groove wall of the receiving groove 1106, and the second air outlet tube 122 together define a pressure cavity 140.

[0089] In some embodiments, the pressure cavity 140 is formed between the first body portion 111 and the second body portion 121, and surrounds the second air outlet tube 122. Specifically, the first wall 113 is connected between the side wall of the first body portion 111 and the first air outlet tube 112, the second wall 123 is connected between the side wall of the second body portion 121 and the second air outlet tube 122, and the pressure cavity 140 can be formed by the first wall 113, the second wall 123, the side wall of the housing 110 connected between the first wall 113 and the second wall 123, and the side wall of the second air outlet tube 122 connected between the first wall 113 and the second wall 123.

Figures 13 to 15

[0091] In some embodiments, as shown in FIG. 12, the atomizer 10 further comprises a second sealing member 151 and a third sealing member 152.

The second sealing member 151 and the third sealing member 152 can seal the connection between the liquid storage chamber 120 and the housing 110, so as to prevent the pressure cavity 140 from leaking from the connection when the internal pressure of the pressure cavity 140 increases, and to prevent the atomized liquid from leaking from the connection through the pressure cavity 140. In addition, during the movement of the atomization assembly 130 from the first position to the second position, the liquid storage chamber 120 and the housing 110 can be relatively fixed under the friction provided by the third sealing member 152; during the movement of the atomization assembly 130 from the second position to the third position, the atomization assembly 130 abuts against the liquid storage chamber 120, so that the liquid storage chamber 120 can move relative to the housing 110 against the friction. Figure 9

[0092] In some embodiments, the second sealing member 151 and the third sealing member 152 can both be sealing rings, and the materials of the second sealing member 151 and the third sealing member 152 can be plastic or rubber materials with elasticity, for example, the materials of the second sealing member 151 and the third sealing member 152 can be silicone, nitrile rubber, or natural rubber, etc.

[0097] Specifically, the power supply assembly 20 is electrically connected with the electrode member 134 of the atomizer 10 to supply power to the heating member 1323.

[0098] In some embodiments, the atomization device can be a disposable product, and the power supply assembly 20 is fixedly connected with the atomizer 10. The atomization device can also be a replaceable and reusable product, and the power supply assembly 20 and the atomizer 10 can be replaced as needed. For example, the atomizer 10 can be a disposable product, and the atomization device can realize the reuse of the power supply assembly 20 by replacing the atomizer 10.

[0099] The atomizer 10 and the atomization device provided by the present application can compress the volume of the pressure chamber 140 between the liquid storage bin 120 and the shell 110, so as to pressurize the liquid storage chamber 1201 when the liquid inlet hole 1301 and the liquid storage chamber 1201 are communicated, and the atomization liquid in the liquid storage chamber 1201 can quickly and fully soak the atomization assembly 130 under the action of pressure, thereby preventing the dry burning from generating a burnt smell, and enabling the atomizer 10 to quickly work to generate aerosol, reducing the waiting time of the user, improving the atomization effect, and greatly improving the user experience. The multi-section buckle design of the atomization assembly 130, the liquid storage bin 120, and the shell 110 can stably separate the atomization liquid and the atomization core 132 when the atomizer 10 is not in use, and at the same time, the compressible pressure chamber 140 can be formed, thereby reducing the debugging difficulty of the atomizer 10 and improving the stability and reliability of the atomizer 10.
