As described in detail below.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic atomization device according to an embodiment of the present invention.

In one embodiment, the electronic atomization device of the utility model can be an electronic cigarette, a medical atomization device, and the like.

The electronic atomization device comprises a host 20 and an atomizer 10, wherein the host 20 is connected with the atomizer 10. The host 20 is a set of basic components for implementing the electronic atomization device, and may include an air sensor, a controller, a power supply, and the like, and may coordinate the components of the electronic atomization device to work cooperatively.

As the name implies, the atomizer 10 has an atomizing action, which refers to an operation of dispersing liquid into minute liquid droplets through a nozzle or with a high-speed air stream. That is, the atomizer 10 is capable of atomizing an aerosol substrate into a spray, and the electronic atomization device described above may be an electronic cigarette, a medical atomization device, or the like, and the aerosol substrate may be a corresponding tobacco tar, a medical atomization liquid, or the like, without limitation.

In this embodiment, the specific implementation of the atomizer 10 will be described in detail below.

Referring to fig. 2 to 4, fig. 2 is a schematic structural view of another embodiment of the electronic atomization device of the present invention, and fig. 3 is a schematic structural view of a cross-section of the electronic atomization device shown in fig. 2 along a direction a-a; fig. 4 is a schematic structural view of the electronic atomizer shown in fig. 3 without a block piece.

In one embodiment, the atomizer 10 includes a housing assembly 110, an atomizing assembly 120, and a closure 130.

The housing assembly 110 is the basic structure of the atomizer 10 and is capable of carrying and protecting the other components of the atomizer 10. The shell is provided with a storage cavity 111, an atomizing cavity 112 and a through hole 113 for communicating the storage cavity 111 and the atomizing cavity 112; the storage chamber 111 is capable of storing an aerosol substrate and the aerosol substrate is capable of flowing through the through-hole 113 to the nebulization chamber 112.

The atomizing assembly 120 is disposed in the atomizing chamber 112 such that when the aerosol substrate flows from the storage chamber 111 to the atomizing chamber 112, the aerosol substrate flows to the atomizing assembly 120, and the atomizing assembly 120 has an atomizing effect capable of atomizing the aerosol substrate into a spray. That is, the atomizing assembly 120 is used to atomize the aerosol substrate flowing from the storage chamber 111 to the atomizing assembly 120.

A blocking member 130 is movably disposed in the housing assembly 110, the blocking member 130 being capable of selectively blocking the through-hole 113 to control whether the storage chamber 111 is in communication with the nebulizing chamber 112, and thereby control the flow of aerosol substrate from the storage chamber 111 to the nebulizing chamber 112.

Specifically, when the nebulizer 10 is not used, the blocking member 130 blocks the through hole 113, the storage chamber 111 is not communicated with the nebulizing chamber 112, the aerosol substrate stored in the storage chamber 111 does not flow to the nebulizing chamber 112, i.e., the aerosol substrate is sealed in the storage chamber 111, so as to avoid leakage of the aerosol substrate, and the nebulizer 10 can be placed with the nebulizing chamber 112 away from the direction of gravity with respect to the storage chamber 111, so that the remaining aerosol substrate in the nebulizing chamber 112 flows to the storage chamber 111, thereby alleviating volatile deterioration of the aerosol substrate due to contact with air; at the same time, it is possible to alleviate prolonged exposure of the aerosol substrate to air by the atomizing assembly 120, which could cause deterioration of the aerosol substrate due to contact with air. When it is desired to use the atomizer 10, the block piece 130 is moved to avoid the through-hole 113, and the aerosol substrate stored in the storage chamber 111 flows from the through-hole 113 to the atomizing chamber 112 to atomize the aerosol substrate by the atomizing assembly 120.

It can thus be seen that in this embodiment, the storage chamber 111 and the nebulization chamber 112 are in communication via the through-hole 113, the blocking member 130 selectively blocks the through-hole 113, so that when it is desired to use the nebulizer 10, the blocking member 130 is moved away from the through-hole 113, the aerosol substrate stored in the storage chamber 111 is passed via the through-hole 113 to the nebulization chamber 112, and the nebulization assembly 120 provided in the nebulization chamber 112 is able to nebulize the aerosol substrate that has passed to the nebulization assembly 120. When the nebulizer 10 is not required to be used or transported, the aerosol substrate is stored in the storage chamber 111 in a closed manner by the blocking piece 130 blocking the through hole 113, thereby alleviating leakage of the aerosol substrate; moreover, the aerosol substrate does not flow to the atomizing cavity 112, and the aerosol substrate is prevented from being retained in the atomizing cavity 112, so that the aerosol substrate is prevented from being exposed to the air through the atomizing assembly 120 for a long time, and the aerosol substrate is prevented from deteriorating due to contact oxidation with the air, which affects the use experience of the user.

Further, when the plugging member 130 plugs the through hole 113, the surface of the plugging member 130 on the side toward the storage chamber 111 must not be lower than the surface of the atomizing chamber 112 on the side toward the storage chamber 111. That is, the surface of the blocking piece 130 facing the storage chamber 111 may be flush with the surface of the storage chamber 111 facing the atomizing chamber 112 (as shown in fig. 3), or higher than the surface of the storage chamber 111 facing the atomizing chamber 112 (not shown), or lower than the surface of the storage chamber 111 facing the atomizing chamber 112 and higher than the surface of the atomizing chamber 112 facing the storage chamber 111 (not shown), which is not limited herein.

Please continue to refer to fig. 2 to 4. In one embodiment, the housing assembly 110 is further provided with a moving passage 114, the moving passage 114 extends toward the storage chamber 111, the extending direction X of the moving passage 114 is parallel to the opposite direction of the storage chamber 111 and the atomizing chamber 112, and the blocking member 130 is inserted into the moving passage 114 and moves along the moving passage 114, so that the blocking member 130 selectively blocks the through hole 113; also, the block piece 130 can be prevented from being separated from its moving path during the movement, thereby improving the reliability of the atomizer 10.

Further, the atomizer 10 further includes a switch member 150, and the housing assembly 110 is further provided with a moving groove 115 communicating with the outside. The extending direction Y of the moving groove 115 is parallel to the extending direction X of the moving channel 114, the switch 150 is disposed through the moving groove 115 and exposed to the outside, and the switch 150 is connected with the plugging member 130 in a clamping manner, so that the plugging member 130 can move along with the user when the user moves the switch 150, that is, the user operates the switch 150 to move along the moving groove 115, and at the same time, the plugging member 130 moves along the moving channel 114, thereby controlling whether the plugging member 130 plugs the through hole 113.

In an alternative embodiment, the switch member 150 may also be a virtual switch or an electronic switch, and the switch member 150 is electrically connected to the blocking member 130, so that when the user switches the switch member 150 to a preset state, the blocking member 130 is controlled to block or avoid the through hole 113 to control whether the storage chamber 111 is communicated with the atomizing chamber 112, and the blocking member 130 may also be controlled to move in other manners, which is not described herein again.

Optionally, the first sealing member 141 is disposed on the outer periphery of the blocking member 130, and a seal is formed between the blocking member 130 and the moving channel 114 through the first sealing member 141, so as to alleviate the aerosol substrate from flowing from the atomizing chamber 112 to the outside of the atomizer 10 through the moving channel 114, and thus contaminating the internal environment of the electronic atomizing apparatus and damaging other components of the electronic atomizing apparatus. That is, the present embodiment can improve the sealability of the atomizer 10.

Please continue to refer to fig. 2 to 4. In one embodiment, the housing assembly 110 further defines a transition passage 116, the through-bore 113 being connected to the atomizing assembly 120 by the transition passage 116, a portion of the transition passage 116 being located between the through-bore 113 and the moving passage 114, the aerosol substrate stored in the storage chamber 111 being flowable through the transition passage 116 to the atomizing assembly 120.

Further, the transition passage 116 includes a first sub-passage 1161 and a second sub-passage 1162 in communication; the first sub-passage 1161 communicates with the through hole 113, and a portion of the first sub-passage 1161 is located between the through hole 113 and the moving passage 114; the first sub-passage 1161 communicates with the atomizing assembly 120 through the second sub-passage 1162. That is, in this embodiment, when the block piece 130 is clear of the through hole 113, the aerosol substrate flows to the atomizing assembly 120, specifically, from the storage chamber 111 through the through hole 113, the first sub-passage 1161, the second sub-passage 1162, and the atomizing assembly 120 in this order, so that the aerosol substrate flowing thereto is atomized by the atomizing assembly 120.

Still further, the cross-sectional area of the second sub-passage 1162 perpendicular to the extending direction Z thereof gradually decreases in a direction away from the storage chamber 111. That is, the side walls of the second sub-passage 1162 may be tapered or the like to enable the aerosol substrate flowing to the nebulizing chamber 112 to have a tendency to flow towards the nebulizing assembly 120, so that the aerosol substrate flowing to the nebulizing chamber 112 can be nebulized by the nebulizing assembly 120, increasing the nebulizing efficiency of the nebulizer 10.

Please continue to refer to fig. 2 to 4. In an embodiment, the end of the blocking member 130 facing the storage chamber 111 is provided with a second sealing member 142 at its periphery, so that when the blocking member 130 blocks the through hole 113, a seal is formed between the blocking member 130 and the through hole 113 by the second sealing member 142, thereby alleviating the leakage of aerosol substrate from the storage chamber 111 to the nebulizing chamber 112, and improving the sealing performance of the nebulizer 10.

Please continue to refer to fig. 2 to 4. In an embodiment, since the conventional atomizer 10 is prone to malfunction during transportation or storage, there is a certain safety risk, and the conventional atomizer has a large power consumption and wastes resources during long-term storage. In this embodiment, the atomizer 10 further includes a first conductive member 161 and a second conductive member 162 (as shown in fig. 3), the first conductive member 161 and the second conductive member 162 are disposed on the housing assembly 110, the first conductive member 161 is electrically connected to the atomizing assembly 120, and the second conductive member 162 is electrically connected to the host 20; the first conductive element 161 is also connected to the closure 130 to selectively electrically connect with the second conductive element 162 in response to movement of the closure 130.

Alternatively, as illustrated in fig. 3, the blocking member 130 is provided with a connecting groove 131, and the first conductive member 161 is embedded in the connecting groove 131 toward the end of the blocking member 130, so that the first conductive member 161 can move therewith when the blocking member 130 moves.

Specifically, when the blocking member 130 is moved away from the through hole 113 to communicate the storage chamber 111 and the atomizing chamber 112, the first conductive member 161 moves toward the second conductive member 162 along with the blocking member 130, so that the first conductive member 161 can be electrically connected with the second conductive member 162, and thus the paths among the atomizing assembly 120, the first conductive member 161, the second conductive member 162, and the host 20 are conducted, and the host 20 can control the aerosol substrate atomized by the atomizing assembly 120 to flow to the atomizing assembly 120. That is, when the blocking member 130 is moved away from the through hole 113, the first conductive member 161 and the second conductive member 162 are electrically connected, and at the same time, the aerosol substrate in the storage chamber 111 can flow to the atomizing chamber 112 and the atomizing assembly 120, so that the atomizer 10 can operate properly, and the atomizing assembly 120 can atomize the aerosol substrate, thereby improving the safety and reliability of the atomizer 10 and the electronic atomizing device.

When the plugging member 130 plugs the through hole 113 to isolate the storage chamber 111 from the nebulizing chamber 112, the first conductive member 161 moves with the plugging member 130 in a direction away from the second conductive member 162, so that the first conductive member 161 is disconnected from the second conductive member 162, i.e., the nebulizing assembly 120, the first conductive member 161, the second conductive member 162, and the host computer 20 are disconnected. That is to say, when need not the use, through shutoff piece 130 shutoff through-hole 113, can alleviate aerosol matrix and flow to atomizing chamber 112 and atomizing subassembly 120 from storage chamber 111, meanwhile, break off between first conductive component 161 and the second conductive component 162, atomizer 10 is out of work, thereby practice thrift the electric energy, and alleviate the potential safety hazard that the maloperation leads to when the product transports the storage for a long time, and then, be favorable to protecting atomizer 10 and electronic atomization device, improve atomizer 10 and electronic atomization device's security.

Further, first conductive assembly 161 includes first and second conductive members 1611 and 1612, respectively, first and second conductive members 1611 and 1612 being electrically connected to atomizing assembly 120, second conductive assembly 162 includes third and fourth conductive members 1621 and 1622, and first conductive member 1611 is electrically connected to third conductive member 1621; the second conductor 1612 is also connected to the block piece 130 for selective electrical connection with the fourth conductor 1622 in response to movement of the block piece 130.

Alternatively, third conductive member 1621 and fourth conductive member 1622 may be coupled to respective positive and negative poles of a power supply (not shown) of the electronic atomizer, such that when closure member 130 is withdrawn from through-hole 113, the pathways between atomizer assembly 120, first conductive member 1611, second conductive member 1612, third conductive member 1621, fourth conductive member 1622, and the power supply are conducted, such that the power supply can provide power to atomizer assembly 120.

Alternatively, first, second, third and fourth conductive members 1611, 1612, 1621, 1622 may be metal domes or the like, and when blocking member 130 is moved, second conductive member 1612 may be deformed partially to electrically connect with fourth conductive member 1622 and partially fixed with respect to housing assembly 110.

Please continue to refer to fig. 2 to 4. In one embodiment, the atomizer 10 further comprises an air outlet channel 30, the air outlet channel 30 being in communication with the spray outlet to reduce the volume of the atomizer and the electronic atomization device, for example, the spray outlet is a mouthpiece when the electronic atomization device is an electronic cigarette.

The main body 20 further includes an air sensor 21, and the air sensor 21 is disposed in the air outlet passage 30.

The air outlet channel 30 is used for communicating with the outside of the electronic atomization device to keep the air pressure inside and outside the electronic atomization device balanced, and the specific working principle thereof is well known to those skilled in the art and will not be described herein; the air sensor 21 is used for sensing air flow or air pressure change and feeding back corresponding information to the host 20.

Whereas in the conventional nebulizer 10, the nebulizing chamber 112 and the nebulizing assembly 120 may not have aerosol substrate when the air sensor 21 senses the air pressure change, the nebulizer 10 works by receiving the corresponding feedback air pressure change information, which is liable to damage the nebulizer 10 and has a safety hazard.

However, in combination with the embodiments of the first conductive element 161 and the second conductive element 162 described in the above embodiments, specifically, when the blocking member 130 escapes from the through hole 113, the first conductive element 161 and the second conductive element 162 are electrically connected, and the second conductive element 1612 and the fourth conductive element 1622 are electrically connected, so that if the air sensor 21 senses a change in air flow or air pressure, the host 20 can control the atomizing assembly 120 to operate. When the through hole 113 is blocked by the blocking member 130, the aerosol substrate may not exist in the atomizing cavity 112 and the atomizing component 120, and the first conductive component 161 and the second conductive component 162 are not electrically connected, the atomizer 10 and the electronic atomizing device do not work, if the design is that the air sensor 21 senses the air flow or the air pressure change, the atomizing component 120 does not work, so that when the aerosol substrate is relieved and does not flow to the atomizing component 120, the atomizing component 120 is damaged by the mistaken smoking, and the safety and the reliability of the electronic atomizing device are improved.

In summary, the blocking piece of the atomizer and the electronic atomization device can selectively block the through hole, so that the aerosol substrate in the atomization cavity can flow back into the storage cavity when the atomizer and the electronic atomization device are not needed, and then the storage cavity and the atomization cavity are separated by blocking the through hole through the blocking piece, thereby relieving the condition that the aerosol substrate is stored in the atomization cavity for a long time and is in contact with air to deteriorate. That is, the utility model can relieve the deterioration of the aerosol substrate after contacting with air for a long time, and is beneficial to improving the use experience of users.

Further, the first conductive component is connected with the plugging piece so as to be selectively and electrically connected with the second conductive component along with the movement of the plugging piece; when the plugging piece plugs the through hole, the first conductive assembly is not electrically connected with the second conductive assembly, the electronic atomization device can be relieved from working mistakenly in the carrying process at the moment, the air sensor can also be relieved from sensing air pressure or air flow change, and when no aerosol substrate exists in the atomization assembly and the atomization cavity, the atomizer and the electronic atomization device work mistakenly, so that the atomizer and the electronic atomization device are damaged. That is to say, when the plug dodges the through-hole, first electrically conductive subassembly and second electrically conductive subassembly electricity are connected, and meanwhile, the aerosol matrix in the storage intracavity can flow to atomizing chamber and atomizing subassembly to guarantee that the atomizer can normally work, atomizing subassembly can atomize the aerosol matrix, and then improves atomizer and electronic atomization device's security and reliability.

In addition, in the present invention, unless otherwise expressly specified or limited, the terms "connected," "stacked," and the like are to be construed broadly, e.g., as meaning permanently connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
