Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomization, in particular to a leakage prevention device and an electronic vaporization apparatus having the leakage prevention device.BACKGROUND

[0002] A vape includes a vaporizer, and an e-liquid storage chamber and a mouthpiece mounted at both ends of the vaporizer. The vaporizer is a device that heats an aerosol-generating substrate to produce vaporized particles, and vape liquid, also known as e-liquid, is generally used as the aerosol-generating substrate.

[0003] A press-type e-liquid injection mode is an e-liquid injection mode applied to an existing vaporizer to facilitate the user to inject e-liquid by themselves. An e-liquid injection process of the press-type e-liquid injection mode is as follows: turning the vaporizer upside down, pressing an e-liquid injection port control mechanism to open an air inlet which communicates the e-liquid storage chamber and an vaporizing e-liquid chamber, the e-liquid in the e-liquid storage chamber flowing into the vaporizing e-liquid chamber, and releasing or pressing the e-liquid injection port control mechanism again after finishing e-liquid injection to close the air inlet.

[0004] After research, it is found that there are still some shortcomings in the above press-type e-liquid injection mode: under a condition that injecting the e-liquid, the pressure in the vaporizing e-liquid chamber increases, and at the same time, gravity is generated under the condition that the e-liquid in the e-liquid storage chamber flows downward, which makes the pressure inside and outside the vaporizing e-liquid chamber unequal, and it is easy for e-liquid to leak from the mouthpiece.SUMMARY

[0045] FIG. 2 is a schematic structural diagram of an e-liquid sealing assembly of the leakage prevention device according to embodiments of the present application.

[0046] As illustrated in FIG. 1 and FIG. 2, in one embodiment of the present application, under the condition that the leakage-proof element 3 is assembled and connected with the pressing element 5 and the vaporizing element 2, the leakage-proof element 3 is an e-liquid sealing assembly, and the e-liquid sealing assembly includes a first connecting sleeve 32, a connecting piece 33, and a second connecting sleeve 31. The first connecting sleeve 32 and the second connecting sleeve 31 are connected through the connecting piece 33. The first connecting sleeve 32 is sleeved and fixed on the pressing element 5 located at the e-liquid chamber 1. The second connecting sleeve 31 is movably sleeved on an outer wall surface of the vaporizing element 2.

[0047] The first connecting sleeve 32 and the second connecting sleeve 31 are fixedly connected to the connecting piece 33 by welding. In the embodiments, the first connecting sleeve 32 and the second connecting sleeve 31 may be made of hardware material. The first connecting sleeve 32 is sleeved on the pressing element 5, and the second connecting sleeve 31 is sleeved on the vaporizing element 2. The first connecting sleeve 32, the connecting piece 33, and the second connecting sleeve 31 may be welded and fixed to each other, or may be integrally formed, and no specific limitation is imposed on this.

[0048] As illustrated in FIG. 1, in the embodiments of the present application, under the condition that the pressing element 5 moves upward to allow the e-liquid into to be injected into the e-liquid chamber 1 through the e-liquid inlet pipe 11, the first connecting sleeve 32 moves upward with the pressing element 5 to drive the second connecting sleeve 31 to move upward, so as to seal an e-liquid inlet of the vaporizing element 2 and reduce the impact force of the e-liquid in the e-liquid chamber 1 on the vaporizing element 2.

[0049] It should be noted that the second connecting sleeve 31 is sleeved on the vaporizing element 2, and is connected to the pressing element 5 through the e-liquid sealing assembly. The second connecting sleeve 31 is configured to slide on the vaporizing element 2 following the movement of the pressing element 5. Under the condition that the pressing element 5 moves to a state of opening (i.e., not blocking or not sealing) the e-liquid inlet pipe 11, the second connecting sleeve 31 slides to a state of closing (i.e., blocking or sealing) the e-liquid inlet of the vaporizing element 2. Under the condition that the pressing element 5 moves to a state of closing (i.e., blocking or sealing) the e-liquid inlet pipe 11, the second connecting sleeve 31 slides to a state of opening (i.e., not blocking or not sealing) the e-liquid inlet of the vaporizing element 2. By providing the leakage-proof element 3 and establishing a linkage connection between the leakage-proof element 3 and the pressing element 5, the second connecting sleeve 31 of the leakage-proof element 3 moves following the movement of the pressing element 5. Under the condition that the pressing element 5 is in a moving state switching between opening and closing the e-liquid inlet pipe 11, the second connecting sleeve 31 is synchronously in a sliding state switching between closing and opening the e-liquid inlet of the vaporizing element 2. Under the condition that it is switched to the e-liquid inlet pipe 11 being opened, the e-liquid inlet of the vaporizing element 2 is synchronously closed by the second connecting sleeve 31, so that the vaporizing element 2 can be avoided from being impacted by the e-liquid in advance and e-liquid leakage can be avoided. Under the condition that it is switched to the e-liquid inlet pipe 11 being closed, the e-liquid inlet of the vaporizing element 2 is synchronously opened, so as to ensure that the e-liquid can smoothly enter the vaporizing element 2 through the e-liquid inlet. In the embodiments, the e-liquid sealing assembly capable of mechanically following the movement of the pressing element 5 and blocking the e-liquid inlet of the vaporizing element 2 is designed to reduce or eliminate the impact force of the e-liquid on the vaporizing element 2, thereby solving the technical problem that the e-liquid easily leaks from the mouthpiece.

The elastic member 53 is configured to provide a resetting elastic force to the pressing head 54 to drive the pressing rod 52 to move to a state in which the sealing head 51 closes the e-liquid inlet pipe 11. The e-liquid sealing assembly is connected to the pressing rod 52, and under the condition that the pressing rod 52 moves, the e-liquid sealing assembly moves with the pressing rod 52 to drive the second connecting sleeve 31 to realize linkage matching.

[0051] The e-liquid chamber 1 is provided with a first installation cavity 612 and a second installation cavity 613, and the first installation cavity and the second installation cavity are configured to accommodate the pressing element 5. A central axis of the first installation cavity 612 coincides with a central axis of the second installation cavity 613. One end of the second installation cavity 613 is connected to one end of the first installation cavity 612 that extends into the e-liquid chamber 1, and an mounting gap is formed between the second installation cavity 613 and the first installation cavity 612.

The sealing head 51 is mounted on one end of the pressing rod 52 passing through the e-liquid inlet pipe 11, and is configured to seal the e-liquid inlet pipe 11. Under the condition that the pressing rod 52 is pushed inward (in a direction towards the e-liquid storage element 62 in FIG. 1) to drive the sealing head 51 to move away from the e-liquid inlet pipe 11, the e-liquid inlet pipe 11 is opened (i.e., not blocked or not sealed), and under the condition that the pressing rod 52 is pulled outward (in a direction away from the e-liquid storage element 62 in FIG. 1) until the sealing head 51 covers the e-liquid inlet pipe 11, the e-liquid inlet pipe 11 is closed (i.e., blocked or sealed). The pressing head 54 is movably arranged in the first installation cavity 612, and a diameter of the pressing head 54 is greater than an outer diameter of the second installation cavity 613 to act as a pressing limit. The elastic member 53 is mounted in the mounting gap, one end of the elastic member 53 is in contact with a connection between the first installation cavity 612 and the second installation cavity 613, the other end of the elastic member 53 is in contact with the pressing head 54, and the elastic member 53 is configured to provide the resetting elastic force to the pressing head 54. In the embodiments, under the condition that injecting the e-liquid, the pressing head 54 is pressed to overcome the elastic force of the elastic member 53 to drive the pressing rod 52 to move inward, thereby driving the sealing head 51 to move away from the e-liquid inlet pipe 11, so as to open the e-liquid inlet pipe 11, and at the same time, the second connecting sleeve 31 follows and moves to close the e-liquid inlet of the vaporizing element 2. After injecting the e-liquid, the pressing head 54 is released, and under the action of the resetting elastic force of the elastic member 53, the pressing head 54 drives the pressing rod 52 to move outward until the sealing head 51 tightly covers the e-liquid inlet pipe 11, so that the e-liquid inlet pipe 11 is closed, and at the same time, the second connecting sleeve 31 follows and moves to open the e-liquid inlet of the vaporizing element 2. The elastic member 53 may preferably be a spring, which is easy to install and can provide a more stable elastic force.

[0052] As illustrated in FIG. 1, in the embodiments of the present application, one end of the vaporizing element 2 is connected to the air inlet of the e-liquid chamber 1 through a first silica gel seat 41, and another end of the vaporizing element 2 is connected to the air outlet of the e-liquid chamber 1 through a second silica gel seat 42. The e-liquid chamber 1 is formed in a space between the first silica gel seat 41 and the second silica gel seat 42. The first silica gel seat 41 is provided with an e-liquid guiding channel that is in communication with the e-liquid inlet pipe 11 and the e-liquid chamber 1. The above design structure is an existing design structure, and will not be repeated in detail.

[0053] It should be noted that, in order to avoid interference with the movement of the leakage-proof element 3, the first silica gel seat 41 is further provided with an avoidance cavity for avoiding the movement of the leakage-proof element 3.

[0054] FIG. 3 is a schematic structural diagram in which the leakage-proof element of the leakage prevention device of the electronic vaporization apparatus is an e-liquid locking layer according to embodiments of the present application, FIG. 4 is a schematic structural diagram in which the leakage-proof element of the leakage prevention device of the electronic vaporization apparatus is a leakage-proof e-liquid chamber according to embodiments of the present application, and FIG. 5 is another structural schematic diagram in which the leakage-proof element of the leakage prevention device of the electronic vaporization apparatus is a leakage-proof e-liquid chamber according to embodiments of the present application.

[0055] As illustrated in FIG. 3 to FIG. 5, in embodiments of the present application, the leakage-proof element 3 being mounted on the vaporizing element 2 includes one of the leakage-proof element 3 being wrapped and mounted on the outer wall surface of the vaporizing element 2 and the leakage-proof element 3 being mounted on the vaporizing element 2 located at the e-liquid chamber 1.

[0056] It should be noted that the leakage prevention device of the electronic vaporization apparatus can avoid e-liquid leakage by wrapping the leakage-proof element 3 on the outer wall surface of the vaporizing element 2 or mounting the leakage-proof element 3 on the vaporizing element 2 located at the e-liquid chamber 1.

[0057] As illustrated in FIG. 3, in one embodiment of the present application, under the condition that the leakage-proof element 3 is wrapped and mounted on the outer wall surface of the vaporizing element 2, the leakage-proof element 3 is an e-liquid locking layer 301 made of cotton, and the e-liquid locking layer 301 is configured to improve the e-liquid locking capacity of the vaporizing element 2 to reduce or eliminate the impact force of the e-liquid in the e-liquid chamber 1 on the vaporizing element 2.

[0058] It should be noted that the e-liquid locking layer 301 is wrapped and mounted on the outer wall surface of the vaporizing element 2, that is, the e-liquid locking layer 301 is added to the outer wall surface of the vaporizing element 2. This structure can improve the e-liquid locking capacity of the vaporizing element 2 so that the e-liquid in the e-liquid chamber 1 does not directly impact the vaporizing element 2, thereby avoiding e-liquid leakage. It will not cause the phenomenon that under the condition that injecting the e-liquid by pressing the electronic vaporization apparatus, the pressure in the e-liquid chamber 1 increases, resulting in an increase in the force of the e-liquid impacting the atomization element 2, and making the e-liquid prone to leakage from a mouthpiece 611. In the embodiments, a length of the e-liquid locking layer 301 may be set according to a size of the outer wall surface of the vaporizing element 2, so that the e-liquid locking layer 301 can completely wrap the vaporizing element 2. In order to save costs and avoid e-liquid leakage, the e-liquid locking layer 301 may be only provided on the outer wall surface of the vaporizing element 2 close to the e-liquid inlet, for example, the e-liquid locking layer 301 is provided at a position of the outer wall surface of the vaporizing element 2 where the e-liquid inlet is located, and the e-liquid locking layer 301 is not provided on other positions of the outer wall surface of the vaporizing elements 2 located in the e-liquid chamber 1.

[0059] In order to further enhance the e-liquid locking capacity of the vaporizing element 2 and more effectively reduce the impact force of the e-liquid on the vaporizing element 2, in the embodiments of the present application, a high activity adsorption material is filled between the e-liquid locking layer 301 and the outer wall surface of the vaporizing element 2.

[0060] The high activity adsorption material may be selected as silica gel.

[0061] As illustrated in FIG. 4 and FIG. 5, in embodiments of the present application, under the condition that the leakage-proof element 3 is mounted on the vaporizing element 2 located at the e-liquid chamber 1, the leakage-proof element 3 is a leakage-proof e-liquid chamber. The vaporizing element 2 is provided inside the leakage-proof e-liquid chamber, an upper end of the leakage-proof e-liquid chamber is provided with one or more e-liquid inlet holes 311 that are in communication with the e-liquid chamber 1, and the e-liquid in the e-liquid chamber 1 enters the vaporizing element 2 through the leakage-proof e-liquid chamber, so as to reduce or eliminate the impact force of the e-liquid in the e-liquid chamber 1 on the vaporizing element 2.

[0062] It should be noted that the leakage-proof e-liquid chamber is made of silicone gel to achieve better sealing connection effect. In the embodiments, the leakage-proof element 3 is sleeved outside the vaporizing element 2, and a chamber 312 independent of the e-liquid chamber 1 is formed between the leakage-proof element 3 and the vaporizing element 2, thereby forming an independent leakage-proof e-liquid chamber. The e-liquid inlet hole 311, which is configured for the e-liquid in the e-liquid chamber 1 entering the chamber 312, defined on the leakage-proof element 3 is provided at a position higher than a preset distance from the air outlet of the e-liquid chamber 1. The preset distance may be changed and adjusted according to actual needs, and the purpose of setting the preset distance is to ensure that there is a certain distance between the e-liquid inlet hole 311 and a side of the e-liquid chamber 1 provided with the air outlet, so that under the condition that injecting the e-liquid, the e-liquid will be accumulated in an area below the e-liquid inlet hole 311 first, so as to avoid the vaporizing element 2 being impacted by the e-liquid in advance and avoid e-liquid leakage. Since the e-liquid inlet hole 311 is at a certain distance from the side of the e-liquid chamber 1 provided with the air outlet, it is convenient for the e-liquid to enter from the e-liquid inlet hole 311 under the condition that the electronic vaporization apparatus is vaped. Taking the side of the e-liquid chamber 1 provided with the air outlet as an inner and lower surface as an example, the e-liquid inlet hole 311 is preferably provided at a position close to an upper end of the leakage-proof element 3, so as to facilitate the e-liquid in the e-liquid chamber 1 to enter the leakage-proof e-liquid chamber. In general, by designing the independent leakage-proof e-liquid chamber, the impact force of the e-liquid on the vaporizing element 2 is reduced or eliminated, thereby solving the technical problem that the e-liquid easily leaks from the mouthpiece.

[0063] In the embodiments of the present application, one end of the leakage-proof element 3 is in sealing contact with the side of the e-liquid chamber 1 provided with the air outlet, and another end of the leakage-proof element 3 is in sealing connection with a side of the e-liquid chamber 1 provided with the air inlet. It can be understood that the leakage-proof element 3 can be entirely wrapped outside the vaporizing element 2, so that the independent chamber 312 is formed between the leakage-proof element 3 and the vaporizing element 2 through the connection between the leakage-proof element 3 and the e-liquid chamber 1.

[0064] It should be noted that in some embodiments, a plurality of e-liquid inlet holes 311 are provided, and the plurality of e-liquid inlet holes 311 are distributed on the circumference. Under the condition that the plurality of e-liquid inlet holes 311 are provided, the e-liquid can be allowed to flow into the chamber 312 more smoothly. Specifically, a diameter and a number of the e-liquid inlet holes 311 may be changed according to actual needs, and will not be described in detail.

[0065] FIG. 6 is a schematic structural diagram in which the leakage-proof element of the leakage prevention device of the electronic vaporization apparatus is an isolation element according to embodiments of the present application, and FIG. 7 is another schematic structural diagram in which the leakage-proof element of the leakage prevention device of the electronic vaporization apparatus is an isolation element according to embodiments of the present application.

[0066] As illustrated in FIG. 6 and FIG. 7, in embodiments of the present application, under the condition that the leakage-proof element 3 is provided on the e-liquid chamber 1, the leakage-proof element 3 is an isolation element, and the isolation element is mounted on the e-liquid chamber 1 located between the e-liquid inlet pipe 11 and the vaporizing element 2. The isolation element divides the e-liquid chamber 1 into a first e-liquid supply chamber 321 and a second e-liquid supply chamber 322, and an e-liquid supply gap is provided between the first e-liquid supply chamber 321 and the second e-liquid supply chamber 322.

[0067] It should be noted that the isolation element is provided away from the end of the e-liquid chamber 1 where the air outlet is provided, and the e-liquid supply gap through which the e-liquid passes is provided between the isolation element and the e-liquid chamber 1. The leakage-proof element 3 serves to divide the e-liquid chamber 1 into the first e-liquid supply chamber 321 and the second e-liquid supply chamber 322 that is in communication with each other through the e-liquid supply gap. The e-liquid inlet pipe 11 is positioned opposite the first e-liquid supply chamber 321 to ensure that the e-liquid enters the first e-liquid supply chamber 321 first under the condition that injecting the e-liquid, and the vaporizing element 2 is located in the second e-liquid supply chamber 322. In the embodiments, the leakage-proof element 3 is a rib plate structure, which plays a certain isolation and blocking role, and its height can be changed and designed according to actual needs. Preferably, a height of the isolation element may be two-thirds to four-fifths of a height of the e-liquid chamber.

[0068] In the embodiments of the present application, under the condition that injecting the electronic vaporization apparatus in the electronic vaporization apparatus, the e-liquid first enters the first e-liquid supply chamber 321 from the e-liquid storage element 62, and with the continuous injecting of the e-liquid, all the e-liquid does not immediately enter the second e-liquid supply chamber 322 on the right side of the leakage-proof element 3, so that the e-liquid can be avoided from directly impacting the vaporizing element 2 during injecting the e-liquid, thereby avoiding e-liquid leakage caused by the direct impact of the e-liquid. Under the condition that a liquid level of the e-liquid is higher than a height of the leakage preventing element 3 (i.e., the isolation element), the e-liquid exceeds the leakage preventing element 3 and flows into the second e-liquid supply chamber 322, so that the vaporizing element 2 can be avoided from being impacted by the e-liquid in advance and e-liquid leakage can be avoided. Since the e-liquid supply gap is formed between the leakage-proof element 3 and the e-liquid chamber 1, under the condition that the electronic vaporization apparatus is vaped, the e-liquid normally flows into the second e-liquid supply chamber through the e-liquid supply gap and enters the vaporizing element 2.

[0069] It should be noted that the electronic vaporization apparatus reduces or eliminates the impact force of the e-liquid on the vaporizing element 2 by designing the isolation element that plays a certain isolation and blocking role, thereby solving the problem that the e-liquid easily leaks from the mouthpiece 611.

[0070] In the embodiments of the present application, in order to facilitate processing, the isolation element may be designed as an integral structure with the e-liquid chamber 1, or the isolation element may be detachably connected to the e-liquid chamber 1.

[0071] It should be noted that under the condition that the isolation element and the e-liquid chamber 1 are detachably connected, a slot may be provided on the e-liquid chamber 1, and the isolation element may be detachably inserted and fitted with the slot. Furthermore, in order to achieve a better sealing connection effect, the isolation element is designed to be made of silica gel material, and under the condition that inserted through the slot, it can achieve a better sealing fit with the slot. In the embodiments, the isolation element may also be provided with a connecting part on one side away from the side of the e-liquid chamber 1 provided with the air outlet, the connecting part extends to the side of the e-liquid chamber 1 provided with the air inlet and is fixed, and the connecting part is a rod or strip structure to ensure that the e-liquid supply gap can still be formed. The other side of the isolation element away from the connecting part and both ends of the isolation element are in sealed contact with the e-liquid chamber 1. The isolation element is configured to divide an e-liquid chamber of the e-liquid chamber 1 into the first e-liquid supply chamber 321 and the second e-liquid supply chamber 322 that is in communication with each other through the e-liquid supply gap. The e-liquid enters the first e-liquid supply chamber 321 of the e-liquid chamber through the e-liquid inlet pipe 11, and then enters the second e-liquid supply chamber 322 through exceeding the isolation element.

The electronic vaporization apparatus includes an vaporizing assembly and an e-liquid storage element for supplying e-liquid to the vaporizing assembly. The vaporizing assembly is provided with an e-liquid inlet pipe, a pressing element, an e-liquid chamber, and an vaporizing element.

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomization, in particular to a leakage prevention device and an electronic vaporization apparatus having the leakage prevention device.BACKGROUND

[0002] A vape includes a vaporizer, and an e-liquid storage chamber and a mouthpiece mounted at both ends of the vaporizer. The vaporizer is a device that heats an aerosol-generating substrate to produce vaporized particles, and vape liquid, also known as e-liquid, is generally used as the aerosol-generating substrate.

[0003] A press-type e-liquid injection mode is an e-liquid injection mode applied to an existing vaporizer to facilitate the user to inject e-liquid by themselves. An e-liquid injection process of the press-type e-liquid injection mode is as follows: turning the vaporizer upside down, pressing an e-liquid injection port control mechanism to open an air inlet which communicates the e-liquid storage chamber and an vaporizing e-liquid chamber, the e-liquid in the e-liquid storage chamber flowing into the vaporizing e-liquid chamber, and releasing or pressing the e-liquid injection port control mechanism again after finishing e-liquid injection to close the air inlet.

[0004] After research, it is found that there are still some shortcomings in the above press-type e-liquid injection mode: under a condition that injecting the e-liquid, the pressure in the vaporizing e-liquid chamber increases, and at the same time, gravity is generated under the condition that the e-liquid in the e-liquid storage chamber flows downward, which makes the pressure inside and outside the vaporizing e-liquid chamber unequal, and it is easy for e-liquid to leak from the mouthpiece.SUMMARY

The technical problem that the e-liquid in the e-liquid chamber of the existing vape structure is easy to leak from the mouthpiece during the e-liquid injecting process, causing inconvenience to users.

[0045] FIG. 2 is a schematic structural diagram of an e-liquid sealing assembly of the leakage prevention device according to embodiments of the present application.

[0046] As illustrated in FIG. 1 and FIG. 2, in one embodiment of the present application, under the condition that the leakage-proof element 3 is assembled and connected with the pressing element 5 and the vaporizing element 2, the leakage-proof element 3 is an e-liquid sealing assembly, and the e-liquid sealing assembly includes a first connecting sleeve 32, a connecting piece 33, and a second connecting sleeve 31. The first connecting sleeve 32 and the second connecting sleeve 31 are connected through the connecting piece 33. The first connecting sleeve 32 is sleeved and fixed on the pressing element 5 located at the e-liquid chamber 1. The second connecting sleeve 31 is movably sleeved on an outer wall surface of the vaporizing element 2.

[0047] The first connecting sleeve 32 and the second connecting sleeve 31 are fixedly connected to the connecting piece 33 by welding. In the embodiments, the first connecting sleeve 32 and the second connecting sleeve 31 may be made of hardware material. The first connecting sleeve 32 is sleeved on the pressing element 5, and the second connecting sleeve 31 is sleeved on the vaporizing element 2. The first connecting sleeve 32, the connecting piece 33, and the second connecting sleeve 31 may be welded and fixed to each other, or may be integrally formed, and no specific limitation is imposed on this.

[0048] As illustrated in FIG. 1, in the embodiments of the present application, under the condition that the pressing element 5 moves upward to allow the e-liquid into to be injected into the e-liquid chamber 1 through the e-liquid inlet pipe 11, the first connecting sleeve 32 moves upward with the pressing element 5 to drive the second connecting sleeve 31 to move upward, so as to seal an e-liquid inlet of the vaporizing element 2 and reduce the impact force of the e-liquid in the e-liquid chamber 1 on the vaporizing element 2.

[0049] It should be noted that the second connecting sleeve 31 is sleeved on the vaporizing element 2, and is connected to the pressing element 5 through the e-liquid sealing assembly. The second connecting sleeve 31 is configured to slide on the vaporizing element 2 following the movement of the pressing element 5. Under the condition that the pressing element 5 moves to a state of opening (i.e., not blocking or not sealing) the e-liquid inlet pipe 11, the second connecting sleeve 31 slides to a state of closing (i.e., blocking or sealing) the e-liquid inlet of the vaporizing element 2. Under the condition that the pressing element 5 moves to a state of closing (i.e., blocking or sealing) the e-liquid inlet pipe 11, the second connecting sleeve 31 slides to a state of opening (i.e., not blocking or not sealing) the e-liquid inlet of the vaporizing element 2. By providing the leakage-proof element 3 and establishing a linkage connection between the leakage-proof element 3 and the pressing element 5, the second connecting sleeve 31 of the leakage-proof element 3 moves following the movement of the pressing element 5. Under the condition that the pressing element 5 is in a moving state switching between opening and closing the e-liquid inlet pipe 11, the second connecting sleeve 31 is synchronously in a sliding state switching between closing and opening the e-liquid inlet of the vaporizing element 2. Under the condition that it is switched to the e-liquid inlet pipe 11 being opened, the e-liquid inlet of the vaporizing element 2 is synchronously closed by the second connecting sleeve 31, so that the vaporizing element 2 can be avoided from being impacted by the e-liquid in advance and e-liquid leakage can be avoided. Under the condition that it is switched to the e-liquid inlet pipe 11 being closed, the e-liquid inlet of the vaporizing element 2 is synchronously opened, so as to ensure that the e-liquid can smoothly enter the vaporizing element 2 through the e-liquid inlet. In the embodiments, the e-liquid sealing assembly capable of mechanically following the movement of the pressing element 5 and blocking the e-liquid inlet of the vaporizing element 2 is designed to reduce or eliminate the impact force of the e-liquid on the vaporizing element 2, thereby solving the technical problem that the e-liquid easily leaks from the mouthpiece.

The elastic member 53 is configured to provide a resetting elastic force to the pressing head 54 to drive the pressing rod 52 to move to a state in which the sealing head 51 closes the e-liquid inlet pipe 11. The e-liquid sealing assembly is connected to the pressing rod 52, and under the condition that the pressing rod 52 moves, the e-liquid sealing assembly moves with the pressing rod 52 to drive the second connecting sleeve 31 to realize linkage matching.

[0051] The e-liquid chamber 1 is provided with a first installation cavity 612 and a second installation cavity 613, and the first installation cavity and the second installation cavity are configured to accommodate the pressing element 5. A central axis of the first installation cavity 612 coincides with a central axis of the second installation cavity 613. One end of the second installation cavity 613 is connected to one end of the first installation cavity 612 that extends into the e-liquid chamber 1, and an mounting gap is formed between the second installation cavity 613 and the first installation cavity 612.

The sealing head 51 is mounted on one end of the pressing rod 52 passing through the e-liquid inlet pipe 11, and is configured to seal the e-liquid inlet pipe 11. Under the condition that the pressing rod 52 is pushed inward (in a direction towards the e-liquid storage element 62 in FIG. 1) to drive the sealing head 51 to move away from the e-liquid inlet pipe 11, the e-liquid inlet pipe 11 is opened (i.e., not blocked or not sealed), and under the condition that the pressing rod 52 is pulled outward (in a direction away from the e-liquid storage element 62 in FIG. 1) until the sealing head 51 covers the e-liquid inlet pipe 11, the e-liquid inlet pipe 11 is closed (i.e., blocked or sealed). The pressing head 54 is movably arranged in the first installation cavity 612, and a diameter of the pressing head 54 is greater than an outer diameter of the second installation cavity 613 to act as a pressing limit. The elastic member 53 is mounted in the mounting gap, one end of the elastic member 53 is in contact with a connection between the first installation cavity 612 and the second installation cavity 613, the other end of the elastic member 53 is in contact with the pressing head 54, and the elastic member 53 is configured to provide the resetting elastic force to the pressing head 54. In the embodiments, under the condition that injecting the e-liquid, the pressing head 54 is pressed to overcome the elastic force of the elastic member 53 to drive the pressing rod 52 to move inward, thereby driving the sealing head 51 to move away from the e-liquid inlet pipe 11, so as to open the e-liquid inlet pipe 11, and at the same time, the second connecting sleeve 31 follows and moves to close the e-liquid inlet of the vaporizing element 2. After injecting the e-liquid, the pressing head 54 is released, and under the action of the resetting elastic force of the elastic member 53, the pressing head 54 drives the pressing rod 52 to move outward until the sealing head 51 tightly covers the e-liquid inlet pipe 11, so that the e-liquid inlet pipe 11 is closed, and at the same time, the second connecting sleeve 31 follows and moves to open the e-liquid inlet of the vaporizing element 2. The elastic member 53 may preferably be a spring, which is easy to install and can provide a more stable elastic force.

[0052] As illustrated in FIG. 1, in the embodiments of the present application, one end of the vaporizing element 2 is connected to the air inlet of the e-liquid chamber 1 through a first silica gel seat 41, and another end of the vaporizing element 2 is connected to the air outlet of the e-liquid chamber 1 through a second silica gel seat 42. The e-liquid chamber 1 is formed in a space between the first silica gel seat 41 and the second silica gel seat 42. The first silica gel seat 41 is provided with an e-liquid guiding channel that is in communication with the e-liquid inlet pipe 11 and the e-liquid chamber 1. The above design structure is an existing design structure, and will not be repeated in detail.

[0053] It should be noted that, in order to avoid interference with the movement of the leakage-proof element 3, the first silica gel seat 41 is further provided with an avoidance cavity for avoiding the movement of the leakage-proof element 3.

[0054] FIG. 3 is a schematic structural diagram in which the leakage-proof element of the leakage prevention device of the electronic vaporization apparatus is an e-liquid locking layer according to embodiments of the present application, FIG. 4 is a schematic structural diagram in which the leakage-proof element of the leakage prevention device of the electronic vaporization apparatus is a leakage-proof e-liquid chamber according to embodiments of the present application, and FIG. 5 is another structural schematic diagram in which the leakage-proof element of the leakage prevention device of the electronic vaporization apparatus is a leakage-proof e-liquid chamber according to embodiments of the present application.

[0055] As illustrated in FIG. 3 to FIG. 5, in embodiments of the present application, the leakage-proof element 3 being mounted on the vaporizing element 2 includes one of the leakage-proof element 3 being wrapped and mounted on the outer wall surface of the vaporizing element 2 and the leakage-proof element 3 being mounted on the vaporizing element 2 located at the e-liquid chamber 1.

[0056] It should be noted that the leakage prevention device of the electronic vaporization apparatus can avoid e-liquid leakage by wrapping the leakage-proof element 3 on the outer wall surface of the vaporizing element 2 or mounting the leakage-proof element 3 on the vaporizing element 2 located at the e-liquid chamber 1.

[0057] As illustrated in FIG. 3, in one embodiment of the present application, under the condition that the leakage-proof element 3 is wrapped and mounted on the outer wall surface of the vaporizing element 2, the leakage-proof element 3 is an e-liquid locking layer 301 made of cotton, and the e-liquid locking layer 301 is configured to improve the e-liquid locking capacity of the vaporizing element 2 to reduce or eliminate the impact force of the e-liquid in the e-liquid chamber 1 on the vaporizing element 2.

[0058] It should be noted that the e-liquid locking layer 301 is wrapped and mounted on the outer wall surface of the vaporizing element 2, that is, the e-liquid locking layer 301 is added to the outer wall surface of the vaporizing element 2. This structure can improve the e-liquid locking capacity of the vaporizing element 2 so that the e-liquid in the e-liquid chamber 1 does not directly impact the vaporizing element 2, thereby avoiding e-liquid leakage. It will not cause the phenomenon that under the condition that injecting the e-liquid by pressing the electronic vaporization apparatus, the pressure in the e-liquid chamber 1 increases, resulting in an increase in the force of the e-liquid impacting the atomization element 2, and making the e-liquid prone to leakage from a mouthpiece 611. In the embodiments, a length of the e-liquid locking layer 301 may be set according to a size of the outer wall surface of the vaporizing element 2, so that the e-liquid locking layer 301 can completely wrap the vaporizing element 2. In order to save costs and avoid e-liquid leakage, the e-liquid locking layer 301 may be only provided on the outer wall surface of the vaporizing element 2 close to the e-liquid inlet, for example, the e-liquid locking layer 301 is provided at a position of the outer wall surface of the vaporizing element 2 where the e-liquid inlet is located, and the e-liquid locking layer 301 is not provided on other positions of the outer wall surface of the vaporizing elements 2 located in the e-liquid chamber 1.

[0059] In order to further enhance the e-liquid locking capacity of the vaporizing element 2 and more effectively reduce the impact force of the e-liquid on the vaporizing element 2, in the embodiments of the present application, a high activity adsorption material is filled between the e-liquid locking layer 301 and the outer wall surface of the vaporizing element 2.

[0060] The high activity adsorption material may be selected as silica gel.

[0061] As illustrated in FIG. 4 and FIG. 5, in embodiments of the present application, under the condition that the leakage-proof element 3 is mounted on the vaporizing element 2 located at the e-liquid chamber 1, the leakage-proof element 3 is a leakage-proof e-liquid chamber. The vaporizing element 2 is provided inside the leakage-proof e-liquid chamber, an upper end of the leakage-proof e-liquid chamber is provided with one or more e-liquid inlet holes 311 that are in communication with the e-liquid chamber 1, and the e-liquid in the e-liquid chamber 1 enters the vaporizing element 2 through the leakage-proof e-liquid chamber, so as to reduce or eliminate the impact force of the e-liquid in the e-liquid chamber 1 on the vaporizing element 2.

[0062] It should be noted that the leakage-proof e-liquid chamber is made of silicone gel to achieve better sealing connection effect. In the embodiments, the leakage-proof element 3 is sleeved outside the vaporizing element 2, and a chamber 312 independent of the e-liquid chamber 1 is formed between the leakage-proof element 3 and the vaporizing element 2, thereby forming an independent leakage-proof e-liquid chamber. The e-liquid inlet hole 311, which is configured for the e-liquid in the e-liquid chamber 1 entering the chamber 312, defined on the leakage-proof element 3 is provided at a position higher than a preset distance from the air outlet of the e-liquid chamber 1. The preset distance may be changed and adjusted according to actual needs, and the purpose of setting the preset distance is to ensure that there is a certain distance between the e-liquid inlet hole 311 and a side of the e-liquid chamber 1 provided with the air outlet, so that under the condition that injecting the e-liquid, the e-liquid will be accumulated in an area below the e-liquid inlet hole 311 first, so as to avoid the vaporizing element 2 being impacted by the e-liquid in advance and avoid e-liquid leakage. Since the e-liquid inlet hole 311 is at a certain distance from the side of the e-liquid chamber 1 provided with the air outlet, it is convenient for the e-liquid to enter from the e-liquid inlet hole 311 under the condition that the electronic vaporization apparatus is vaped. Taking the side of the e-liquid chamber 1 provided with the air outlet as an inner and lower surface as an example, the e-liquid inlet hole 311 is preferably provided at a position close to an upper end of the leakage-proof element 3, so as to facilitate the e-liquid in the e-liquid chamber 1 to enter the leakage-proof e-liquid chamber. In general, by designing the independent leakage-proof e-liquid chamber, the impact force of the e-liquid on the vaporizing element 2 is reduced or eliminated, thereby solving the technical problem that the e-liquid easily leaks from the mouthpiece.

[0063] In the embodiments of the present application, one end of the leakage-proof element 3 is in sealing contact with the side of the e-liquid chamber 1 provided with the air outlet, and another end of the leakage-proof element 3 is in sealing connection with a side of the e-liquid chamber 1 provided with the air inlet. It can be understood that the leakage-proof element 3 can be entirely wrapped outside the vaporizing element 2, so that the independent chamber 312 is formed between the leakage-proof element 3 and the vaporizing element 2 through the connection between the leakage-proof element 3 and the e-liquid chamber 1.

[0064] It should be noted that in some embodiments, a plurality of e-liquid inlet holes 311 are provided, and the plurality of e-liquid inlet holes 311 are distributed on the circumference. Under the condition that the plurality of e-liquid inlet holes 311 are provided, the e-liquid can be allowed to flow into the chamber 312 more smoothly. Specifically, a diameter and a number of the e-liquid inlet holes 311 may be changed according to actual needs, and will not be described in detail.

[0065] FIG. 6 is a schematic structural diagram in which the leakage-proof element of the leakage prevention device of the electronic vaporization apparatus is an isolation element according to embodiments of the present application, and FIG. 7 is another schematic structural diagram in which the leakage-proof element of the leakage prevention device of the electronic vaporization apparatus is an isolation element according to embodiments of the present application.

[0066] As illustrated in FIG. 6 and FIG. 7, in embodiments of the present application, under the condition that the leakage-proof element 3 is provided on the e-liquid chamber 1, the leakage-proof element 3 is an isolation element, and the isolation element is mounted on the e-liquid chamber 1 located between the e-liquid inlet pipe 11 and the vaporizing element 2. The isolation element divides the e-liquid chamber 1 into a first e-liquid supply chamber 321 and a second e-liquid supply chamber 322, and an e-liquid supply gap is provided between the first e-liquid supply chamber 321 and the second e-liquid supply chamber 322.

[0067] It should be noted that the isolation element is provided away from the end of the e-liquid chamber 1 where the air outlet is provided, and the e-liquid supply gap through which the e-liquid passes is provided between the isolation element and the e-liquid chamber 1. The leakage-proof element 3 serves to divide the e-liquid chamber 1 into the first e-liquid supply chamber 321 and the second e-liquid supply chamber 322 that is in communication with each other through the e-liquid supply gap. The e-liquid inlet pipe 11 is positioned opposite the first e-liquid supply chamber 321 to ensure that the e-liquid enters the first e-liquid supply chamber 321 first under the condition that injecting the e-liquid, and the vaporizing element 2 is located in the second e-liquid supply chamber 322. In the embodiments, the leakage-proof element 3 is a rib plate structure, which plays a certain isolation and blocking role, and its height can be changed and designed according to actual needs. Preferably, a height of the isolation element may be two-thirds to four-fifths of a height of the e-liquid chamber.

[0068] In the embodiments of the present application, under the condition that injecting the electronic vaporization apparatus in the electronic vaporization apparatus, the e-liquid first enters the first e-liquid supply chamber 321 from the e-liquid storage element 62, and with the continuous injecting of the e-liquid, all the e-liquid does not immediately enter the second e-liquid supply chamber 322 on the right side of the leakage-proof element 3, so that the e-liquid can be avoided from directly impacting the vaporizing element 2 during injecting the e-liquid, thereby avoiding e-liquid leakage caused by the direct impact of the e-liquid. Under the condition that a liquid level of the e-liquid is higher than a height of the leakage preventing element 3 (i.e., the isolation element), the e-liquid exceeds the leakage preventing element 3 and flows into the second e-liquid supply chamber 322, so that the vaporizing element 2 can be avoided from being impacted by the e-liquid in advance and e-liquid leakage can be avoided. Since the e-liquid supply gap is formed between the leakage-proof element 3 and the e-liquid chamber 1, under the condition that the electronic vaporization apparatus is vaped, the e-liquid normally flows into the second e-liquid supply chamber through the e-liquid supply gap and enters the vaporizing element 2.

[0069] It should be noted that the electronic vaporization apparatus reduces or eliminates the impact force of the e-liquid on the vaporizing element 2 by designing the isolation element that plays a certain isolation and blocking role, thereby solving the problem that the e-liquid easily leaks from the mouthpiece 611.

[0070] In the embodiments of the present application, in order to facilitate processing, the isolation element may be designed as an integral structure with the e-liquid chamber 1, or the isolation element may be detachably connected to the e-liquid chamber 1.

[0071] It should be noted that under the condition that the isolation element and the e-liquid chamber 1 are detachably connected, a slot may be provided on the e-liquid chamber 1, and the isolation element may be detachably inserted and fitted with the slot. Furthermore, in order to achieve a better sealing connection effect, the isolation element is designed to be made of silica gel material, and under the condition that inserted through the slot, it can achieve a better sealing fit with the slot. In the embodiments, the isolation element may also be provided with a connecting part on one side away from the side of the e-liquid chamber 1 provided with the air outlet, the connecting part extends to the side of the e-liquid chamber 1 provided with the air inlet and is fixed, and the connecting part is a rod or strip structure to ensure that the e-liquid supply gap can still be formed. The other side of the isolation element away from the connecting part and both ends of the isolation element are in sealed contact with the e-liquid chamber 1. The isolation element is configured to divide an e-liquid chamber of the e-liquid chamber 1 into the first e-liquid supply chamber 321 and the second e-liquid supply chamber 322 that is in communication with each other through the e-liquid supply gap. The e-liquid enters the first e-liquid supply chamber 321 of the e-liquid chamber through the e-liquid inlet pipe 11, and then enters the second e-liquid supply chamber 322 through exceeding the isolation element.

The electronic vaporization apparatus includes an vaporizing assembly and an e-liquid storage element for supplying e-liquid to the vaporizing assembly. The vaporizing assembly is provided with an e-liquid inlet pipe, a pressing element, an e-liquid chamber, and an vaporizing element.
