Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] In a cartridge-replaceable electronic atomization device, the electronic atomization device includes a body and an atomizer. The body is provided with a power supply system. When the atomizer is installed on the body, the power supply system establishes an electrical connection with the atomizer and supplies power to the atomizer.

[0003] The atomizer stores atomized liquid, and the atomizer uses the electrical energy provided by the main body to atomize the atomized liquid. When the atomized liquid in the atomizer is consumed, the atomizer is removed from the main body and a new atomizer is installed, and the electronic atomization device can continue to be used.

[0004] In the related art, the atomizing assembly of the atomizer is arranged at the connection point between the liquid storage chamber and the air flow channel. The atomizer is affected by factors such as changes in air pressure, rising temperature, and shaking, and a small amount of atomized liquid in the liquid storage chamber will leak into the air flow channel. This is a normal phenomenon and does not affect the normal use of the atomizer. However, since the air inlet hole opened on the surface of the shell assembly is directly connected to the air flow channel, while facilitating the air intake of the air flow channel, the atomized liquid leaked into the air flow channel will leak through the air inlet hole to the surface of the shell assembly under the action of gravity, resulting in liquid leakage, which affects the user experience. Utility Model Content

[0005] The main purpose of this application is to provide an atomizer, which aims to improve the problem in existing atomizers that the atomized liquid leaking into the air flow channel will leak through the air inlet to the surface of the shell component under the action of gravity, causing leakage, thereby affecting the user's experience.

[0006] To achieve the above-mentioned purpose, the present application proposes an atomizer, which includes a housing assembly and an atomizing assembly; wherein,

[0007] The shell assembly is provided with an air flow channel, a liquid storage cavity and a buffer cavity. The air outlet end of the air flow channel is exposed on the surface of the shell assembly and is connected to the outside. The air inlet end of the air flow channel is connected to the buffer cavity. The liquid storage cavity is connected to the air flow channel. The atomization assembly is provided at the connection between the liquid storage cavity and the air flow channel.

[0008] The surface of the shell assembly is further provided with at least one air inlet hole, at least one of the air inlet holes is connected to the cache cavity, and in the extension direction of the air flow channel, at least one of the air inlet holes is staggered with the air inlet end.

[0009] In some embodiments of the present application, the air flow channel is arranged along the length direction of the housing assembly. The buffer chamber is located on one side of the housing assembly away from the air outlet end. One side wall of the buffer chamber is communicated with the air inlet end, and the other side wall opposite to the buffer chamber is communicated with at least one of the air inlet holes.

[0010] In some embodiments of the present application, an annular liquid stopping portion is convexly provided on the peripheral edge of one side of the buffer chamber where the air inlet hole is located.

[0011] In some embodiments of the present application, the atomizer further includes a sealing rod, and the sealing rod is inserted and matched with the air flow channel to block the air outlet end and the air inlet end.

[0012] In some embodiments of the present application, a limiting portion for abutting and cooperating with the sealing rod is further provided on one side wall of the buffer chamber away from the air inlet end.

[0013] In some embodiments of the present application, the housing assembly includes an oil cup and a base. The oil cup is provided with a liquid storage tank and the air flow channel. The base is arranged at the opening of the liquid storage tank and covers the opening of the liquid storage tank to enclose and form the liquid storage chamber.

[0014] In some embodiments of the present application, the base includes a sealing member and an end cover. The sealing member abuts and seals against the peripheral wall of the liquid storage tank to enclose and form the liquid storage chamber;

[0015] The end cover is fixedly connected to the oil cup and encloses with the sealing member to form the buffer chamber. The sealing member is further provided with a through hole to communicate the air inlet end with the buffer chamber.

[0016] In some embodiments of the present application, an annular accommodation groove is further concavely provided on the peripheral side of the end cover. The annular accommodation groove is provided with an annular sealing ring, and the annular sealing ring abuts and seals against the peripheral wall of the liquid storage tank.

[0017] In some embodiments of the present application, a liquid absorbing member is further provided in the buffer chamber.

[0018] The present application further provides an electronic atomization device. The electronic atomization device includes a main body and the atomizer as described in any one of the above. The main body is provided with an installation portion and a power supply system. The atomizer is detachably installed on the installation portion, and the power supply system is electrically connected to the atomization component when the atomizer is installed on the installation portion.

[0019] With the above technical solution of the present application, when the atomized liquid in the liquid storage cavity leaks out into the air flow channel, since the air inlet holes are arranged in a dislocation with the air inlet end of the air flow channel, the atomized liquid will drip onto the cavity wall of the buffer cavity under the action of gravity. Therefore, the atomized liquid will not leak along the air inlet holes to the surface of the housing assembly, but is stored in the buffer cavity, thereby avoiding the leakage of the atomized liquid to the surface of the housing assembly. It can be seen that in the technical solution of the present application, by arranging the air inlet holes in a dislocation with the air inlet end of the air flow channel, the atomized liquid leaking from the air flow channel can be stored in the buffer cavity, avoiding the liquid leakage phenomenon that the atomized liquid leaks out to the surface of the housing assembly, so that the surface of the housing assembly can be kept clean, thereby improving the user experience. In addition, for the atomizer provided by the present application, after the user stops sucking, part of the aerosol will remain in the air flow channel. When the aerosol condenses into liquid, it can also flow into the buffer cavity through the air inlet end of the air flow channel for storage, and will not leak out to the surface of the housing assembly to cause a liquid leakage phenomenon.

[0031] The present application provides an atomizer 100, which can be applied to an electronic atomization device. The electronic atomization device includes a main body and the atomizer 100. A power supply system is provided in the main body. When the atomizer 100 is installed on the main body, the power supply system establishes an electrical connection with the atomizer 100 and supplies power to the atomizer 100. Please refer to Figures 1 to 4 In the embodiments of the present application, the atomizer 100 includes a housing assembly 10 and an atomization assembly 20.

[0032] The housing assembly 10 is provided with an air flow channel 13, a liquid storage chamber 14 and a buffer chamber 15. The air outlet end of the air flow channel 13 is exposed on the surface of the housing assembly 10 and is communicated with the outside. The air inlet end of the air flow channel 13 is communicated with the buffer chamber 15. The liquid storage chamber 14 is communicated with the air flow channel 13, and an atomizing assembly 20 is provided at the communication part between the liquid storage chamber 14 and the air flow channel 13; at least one air inlet hole 1121 is further provided on the surface of the housing assembly 10. At least one air inlet hole 1121 is communicated with the buffer chamber 15, and in the extending direction of the air flow channel 13, at least one air inlet hole 1121 is arranged in a dislocation manner with respect to the air inlet end.

[0033] Among them, the liquid storage chamber 14 is used to store the atomizing liquid. It can be understood that the atomizing assembly 20 is located at the communication part between the liquid storage chamber 14 and the air flow channel 13, and the atomizing assembly 20 forms an atomizing space in the air flow channel 13 for atomizing the atomizing liquid. After the atomizing assembly 20 atomizes the atomizing liquid into aerosol, the aerosol can be discharged through the air outlet end under the drive of an external force, and this external force is usually generated by the user sucking on the air outlet end with the mouth.

[0034] The air outlet end of the air flow channel 13 is exposed on the surface of the housing assembly 10 mainly to facilitate the user to suck with the mouth. Therefore, the shape of the air outlet end can be made into a shape convenient for the user to suck. The specific shape of the housing assembly 10 is not specifically limited in this application. In some examples, the housing assembly 10 can be in the shape of a long rod.

[0035] The shape of the air inlet hole 1121 also has various types, such as round hole shape, square hole shape, etc. This application does not specifically limit the shape and quantity of the air inlet hole 1121. The air inlet hole 1121 is mainly used to supplement gas to the buffer chamber 15 when the user sucks with the mouth, so as to maintain the dynamic air pressure balance between the air flow channel 13 and the buffer chamber 15.

[0036] Among them, the fact that at least one air inlet hole 1121 is arranged in a dislocation manner with respect to the air inlet end means that the projection of the air inlet hole 1121 on the horizontal plane and the projection of the air inlet end on the horizontal plane are staggered and do not overlap, and the gas entering the buffer chamber 15 from the air inlet hole 1121 needs to turn in the buffer chamber 15 before entering the air inlet end.

[0037] According to the atomizer 100 of the embodiments of the present application, when the atomizer 100 is applied to an electronic atomization device, the main body of the electronic atomization device provides electrical energy for the atomizer 100, provides the energy required for the normal operation of the atomizer 100, and the atomization component 20 of the atomizer 100 operates using electrical energy to atomize the atomization liquid into aerosol in the air flow channel 13. The user drives the flow of gas by sucking on the air outlet end. As the gas flows, the aerosol in the air flow channel 13 will be inhaled by the user into the mouth. During this process, external gas enters the buffer chamber 15 through the air inlet holes 1121, then flows through the air flow channel 13, and finally drives the aerosol in the air flow channel 13 into the user's mouth together.

[0038] Through the above technical solution of the present application, when the atomization liquid in the liquid storage chamber 14 leaks to the air flow channel 13, since the air inlet holes 1121 are all arranged in a dislocation with the air inlet end of the air flow channel 13, the atomization liquid will drip onto the wall of the buffer chamber 15 under the action of gravity. Therefore, the atomization liquid will not leak along the air inlet holes 1121 to the surface of the housing assembly 10, but is stored in the buffer chamber 15, thereby avoiding the atomization liquid from leaking to the surface of the housing assembly 10. It can be seen that in the technical solution of the present application, by arranging the air inlet holes 1121 in a dislocation with the air inlet end of the air flow channel 13, the atomization liquid leaked from the air flow channel 13 can be stored in the buffer chamber 15, avoiding the liquid leakage phenomenon that the atomization liquid leaks to the surface of the housing assembly 10, keeping the surface of the housing assembly 10 clean, and improving the user experience. In addition, for the atomizer 100 provided by the present application, after the user stops sucking, some aerosol will remain in the air flow channel 13. When the aerosol condenses into liquid, it can also flow into the buffer chamber 15 through the air inlet end of the air flow channel 13 for storage, without leaking to the surface of the housing assembly 10 to cause a liquid leakage phenomenon.

[0039] In some examples, such as Figures 1 to 3 shown, the air flow channel 13 is arranged along the length direction of the housing assembly 10, the buffer chamber 15 is located on the side of the housing assembly 10 away from the air outlet end, one side wall of the buffer chamber 15 is communicated with the air inlet end, and the opposite side wall of the buffer chamber 15 is communicated with at least one air inlet hole 1121.

[0040] Considering that the main body of the electronic atomization device is usually provided with a slot for plugging and matching with the atomizer 100, in this example, the atomizer 100 is integrally in a long rod shape, which is convenient for the atomizer 100 to be plugged and matched with the main body of the electronic atomizer 100. In addition, arranging the air flow channel 13 along the length direction of the housing assembly 10 can reduce the resistance of the gas flow in the air flow channel 13, improve the user's sucking comfort, and also optimize the component layout of the atomizer 100, making full use of the internal space of the housing assembly 10.

[0041] In some examples, such asFigure 3 and Figure 4 As shown in Figure 4 , an annular liquid stop portion 1122 is convexly provided on the peripheral edge of one side of the buffer cavity 15 at the air inlet hole 1121. Such a setting is aimed at preventing the liquid stored in the buffer cavity 15 from leaking to the surface of the housing assembly 10 through the air inlet hole 1121, and improving the liquid storage capacity of the buffer cavity 15.

[0042] Among them, the shape of the inner side of the annular liquid stop portion 1122 can be adapted to the shape of the air inlet hole 1121. That is, when the air inlet hole 1121 is a round hole, the inner cavity of the annular liquid stop portion 1122 can be cylindrical; when the air inlet hole 1121 is a square hole, the inner cavity of the annular liquid stop portion 1122 can be prismatic.

[0043] In some examples, as Figures 1 to 3 shown, the atomizer 100 further includes a sealing rod 30, and the sealing rod 30 is inserted and cooperated with the air flow channel 13 to block the air outlet end and the air inlet end. Such a setting is aimed at blocking the air outlet end and the air inlet end through the sealing rod 30, so that when the atomizer 100 is not in use, the sealing performance can be improved, the leakage of the atomizing liquid can be reduced, and thus the stability of the atomizer 100 in the storage, transportation and other states can be improved.

[0044] Considering that the sealing rod 30 needs to be pulled out when the atomizer 100 is used, the sealing rod 30 usually at least partially protrudes from the air outlet end, so as to facilitate the user to hold the sealing rod 30 and pull out the sealing rod 30.

[0045] In some examples, as Figure 3 and Figure 4 shown, a limiting portion 1123 that is in abutting cooperation with the sealing rod 30 is further provided on the cavity wall of the buffer cavity 15 on the side far from the air inlet end. Such a setting is aimed at preventing the sealing rod 30 from being inserted too deep into the air flow channel 13, which is not convenient for the user to hold the sealing rod 30.

[0046] In some examples, as Figures 2 to 4 shown, the housing assembly 10 includes an oil cup 12 and a base 11. The oil cup 12 is provided with a liquid storage tank and an air flow channel 13. The base 11 is arranged at the opening of the liquid storage tank and covers the opening of the liquid storage tank to enclose and form a liquid storage cavity 14. Such a setting is aimed at facilitating the assembly of the atomizer 100 and improving the assembly efficiency of the atomizer 100.

[0047] Among them, the base 11 can be arranged at the opening of the liquid storage tank through connection relationships such as clamping, bonding, welding, interference fit, etc.

[0048] In some examples, as Figures 2 to 4As shown, the base 11 includes a seal 111 and an end cap 112. The seal 111 abuts against and seals the peripheral wall of the liquid storage tank to enclose and form a liquid storage chamber 14. The end cap 112 is fixedly connected to the oil cup 12 and encloses with the seal 111 to form a buffer chamber 15. The seal 111 is also provided with a through hole to communicate the air inlet end with the buffer chamber 15.

[0049] With such a setting, it is intended to improve the sealing performance of the liquid storage chamber 14 by the seal 111 abutting against and sealing the peripheral wall of the liquid storage tank, and to prevent the atomized liquid stored in the liquid storage chamber 14 from leaking through the gap between the oil cup 12 and the base 11.

[0050] In some examples, as Figure 3 and Figure 4 shown, a ring-shaped accommodation groove 1124 is further recessed on the peripheral side of the end cap 112. The ring-shaped accommodation groove 1124 is provided with a ring-shaped sealing ring 113, and the ring-shaped sealing ring 113 abuts against and seals the peripheral wall of the liquid storage tank. With such a setting, it is intended to improve the sealing performance of the buffer chamber 15 by the ring-shaped sealing ring 113 abutting against and sealing the peripheral wall of the liquid storage tank, and to prevent the atomized liquid and condensate stored in the buffer chamber 15 from leaking through the gap between the oil cup 12 and the end cap 112.

[0051] In some examples, as Figure 3 and Figure 4 shown, a liquid absorbing member 40 is further provided in the buffer chamber 15. With such a setting, it is intended to prevent the atomized liquid and condensate from flowing in the buffer chamber 15 by the absorption of the liquid absorbing member 40 on the atomized liquid and condensate, and further prevent the atomized liquid and condensate from flowing out through the gap or the air inlet hole 1121.

[0052] Please combine with the above-mentioned content that the buffer chamber 15 is located on the side of the housing assembly 10 away from the air outlet end. The liquid absorbing member 40 is arranged on the side of the buffer chamber 15 away from the air inlet end and avoids the air inlet hole 1121 to keep the gas flow smooth.

[0053] Please combine with the above-mentioned content that a ring-shaped liquid stopping portion 1122 protrudes on the peripheral edge of one side of the buffer chamber 15 where the air inlet hole 1121 is located. The thickness of the liquid absorbing member 40 is less than the length of the ring-shaped liquid stopping portion 1122 to keep the gas flow smooth.

[0054] Please combine with the inner cylinder of the sealing rod 30 mentioned above. The liquid absorbing member 40 also avoids the limiting portion 1123.

[0055] Among them, the liquid absorbing member 40 can be made of materials such as cotton and glass fiber.

[0056] The present application also provides an electronic atomization device, which includes a main body and an atomizer 100. The specific structure of the atomizer 100 refers to the above embodiments. Since this electronic atomization device adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here. Among them, the main body is provided with an installation part and a power supply system. The atomizer 100 is detachably installed on the installation part. When the atomizer 100 is installed on the installation part, the power supply system is electrically connected to the atomization component 20.

[0057] In some examples, the atomizer 100 further includes a receiving electrode. Combining the above-mentioned content that the buffer cavity 15 is located on the side of the housing assembly 10 away from the air outlet end, the receiving electrode is installed on the side of the housing assembly 10 away from the air outlet end. The receiving electrode is also electrically connected to the atomization component 20 through a wire. Among them, at least part of the receiving electrode is exposed on the outer surface of the housing assembly 10 and is arranged adjacent to the air inlet hole 1121. The power supply system includes an electrode pin and a battery. The electrode pin is electrically connected to the battery through a wire. When the atomizer 100 is installed on the installation part, the receiving electrode contacts the electrode pin, so that the atomization component 20 establishes an electrical connection with the battery through the contact between the receiving electrode and the electrode pin.
