FIELD

The present application relates to the field of vaporization technologies, and in particular, to a vaporizer and an electronic vaporization device.

BACKGROUND

An aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in an air medium. The aerosol can be absorbed by human body through the respiratory system, providing a user with a novel alternative absorption manner. For example, as an alternative to a conventional product form and absorption manner, a vaporization device generating an aerosol by baking and heating aerosol generation substrates such as herbs or pastes is applied to different fields to deliver an inhalable aerosol to the user.

Referring to FIG. 1 and FIG. 2, an embodiment of the present application provides an electronic vaporization device 100. The electronic vaporization device 100 includes a vaporizer 10, and the vaporizer 10 can be configured to heat and vaporize aerosol generation substrates such as flowers and leaves, herbs or pastes.

The vaporizer 10 includes a first housing 11 and an electrode holder 12, and the electrode holder 12 is provided with an electrode. Referring to FIG. 3 and FIG. 4, the vaporizer 10 further includes a matching structure, and the matching structure includes a first matching portion 131 and a second matching portion 132. The first matching portion 131 is arranged on one of the first housing 11 and the electrode holder 12, and the second matching portion 132 is arranged on the other of the first housing 11 and the electrode holder 12. That is, the first matching portion 131 and the second matching portion 132 are neither simultaneously arranged on the housing 11, nor simultaneously arranged on the electrode holder 12. Specifically, when the first matching portion 131 is arranged on the housing 11, the second matching portion 132 is arranged on the electrode holder 12; and when the first matching portion 131 is arranged on the electrode holder 12, the second matching portion 132 is arranged on the housing 11. The first matching portion 131 is matched with the second matching portion 132 in an anti-rotation manner in a circumferential direction of the vaporizer 10. That is, the first matching portion 131 is matched with the second matching portion 132 to limit mutual rotation between the electrode holder 12 and the first housing 11 in the circumferential direction of the vaporizer 10.

With the foregoing arrangement, relative positions of the electrode holder 12 and the first housing 11 in the circumferential direction of the vaporizer 10 do not change easily. Therefore, a position of the electrode arranged on the electrode holder 12 does not change easily, the vaporization assembly 15 is kept connected to a power supply 32 through the electrode at all times, and positions of other components that are in contact with the electrode holder 12 do not change easily, to ensured that various components in the vaporizer 10 closely match with each other, thereby improving the product yield.

Referring to FIG. 5, in an embodiment, the first housing 11 includes a first body 111 and a first mounting ring 112, and the first mounting ring 112 is arranged in the first body 111. The electrode holder 12 includes a base body 121 and a first electrode 122 arranged on the base body 121 (referring to FIG. 3), and at least part of the base body 121 is arranged in the first mounting ring 112. One of the first matching portion 131 and the second matching portion 132 is arranged on the base body 121, and the other is arranged in the first mounting ring 112. That is, the first matching portion 131 and the second matching portion 132 are neither simultaneously arranged on the base body 121, nor simultaneously arranged on the first mounting ring 112. Specifically, when the first matching portion 131 is arranged in the first mounting ring 112, the second matching portion 132 is arranged on the base body 121; and when the first matching portion 131 is arranged on the base body 121, the second matching portion 132 is arranged in the mounting ring 112. The first mounting ring 112 and the base body 121 are both made of conductive materials. For example, both the first mounting ring 112 and the base body 121 are made of metal materials. In this way, the first electrode 122 arranged on the base body 121 may be connected to the power supply 32 through the base body 121 and the first mounting ring 112. It should be understood that, in other embodiments, the arrangement manner of the first housing 11 and the electrode holder 12 is not limited to the foregoing manner. For example, the first housing 11 may include only the first body 111, and the electrode holder 12 may include only the base body 121.

Specifically, the first body 111 is cylindrical with openings at both ends in an axial direction, and the first mounting ring 112 is annular. Certainly, in other embodiments, specific shapes of the first body 111 and the first mounting ring 112 are not limited.

In an embodiment, the first matching portion 131 is a protrusion protruding from one of the first mounting ring 112 and the base body 121. The second matching portion 132 is a groove recessed in the other of the first mounting ring 112 and the base body 121. The protrusion is embedded in the groove, and the protrusion is embedded in the groove in an anti-rotation manner in the circumferential direction of the vaporizer 10 to restrict rotation of the base body 121 relative to the first mounting ring 112. Specifically, the base body 121 is detachably connected to the first mounting ring 112, and both the groove and the protrusion extend in the axial direction of the vaporizer 10. That is, the first matching portion 131 is detachably matched with the second matching portion 132 in the axial direction of the vaporizer 10. In this way, the first matching portion 131 is matched with the second matching portion 132 to allow the base body 121 and the first mounting ring 112 to be separated from each other. That is, in this embodiment, the first matching portion 131 is matched with the second matching portion 132 to restrict the rotation of the electrode holder 12 relative to the first housing 11. However, the matching of the first matching portion 131 and the second matching portion 132 does not restrict detachment of the electrode holder 12 from the first housing 11 in the axial direction. In addition, through detachable connection between the base body 121 and the first mounting ring 112, it is convenient to separately clean the electrode holder 12 and the first housing 11.

Further, a cross-sectional shape of the protrusion is a zigzag shape arranged in the circumferential direction of the vaporizer 10, and a cross-sectional shape of the groove matches the cross-sectional shape of the protrusion to increase the anti-rotation effect. It is conceivable that, in other embodiments, specific structures of the first matching portion 131 and the second matching portion 132 are not limited, provided that the electrode holder 12 can be restricted from rotating relative to the first housing 11 while can be detached from the first housing 11.

In an embodiment, the first electrode 122 is an annular shape arranged in the circumferential direction of the vaporizer 10, and the first electrode 122 is sleeved outside an end of the base body 121 that extends into the first mounting ring 112. A first opening 1221 (referring to FIG. 3) in communication with the outside runs through the first electrode 122 in a thickness direction (a radial direction of the vaporizer 10), and a second opening 1121 (referring to FIG. 5) runs through the first mounting ring 112 in the thickness direction. A first air outlet channel 14 (referring to FIG. 6) is provided between the first mounting ring 112 and an inner wall of the first body 111. The first air outlet channel 14, the second opening 1121 and the first opening 1221 are sequentially communicated. In this way, the external air can flow through the first opening 1221 to the second opening 1121, and flow out from the second opening 1121 to the first air outlet channel 14.

Optionally, in the circumferential direction of the vaporizer 10, a width of the first opening 1221 is greater than a width of the second opening 1121. In this way, during mounting of the electrode holder 12, communication between the second opening 1121 and the second opening 1121 is ensured without requiring precise alignment in the circumferential direction, so as to ensure smooth airflow. Certainly, in some other embodiments, the width of the first opening 1221 may alternatively be equal to or less than the width of the second opening 1121, which is not limited herein.

Specifically, a plurality of the first openings 1221 spaced apart from each other are arranged in the circumferential direction of the vaporizer 10. The quantity of the second openings 1121 matches the quantity of the first openings 1221 to ensure smooth airflow. Certainly, in some other embodiments, there may also be only one first opening 1221 and one second opening 1121. Referring to FIG. 6, in an embodiment, the electrode holder 12 further includes a first insulating member 123 and a second electrode 124. The second electrode 124 extends out of the base body 121, and the first insulating member 123 is sleeved between the second electrode 124 and the base body 121 to block electrical connection between the first electrode 122 and the second electrode 124. Referring to FIG. 7, an air inlet channel 1241 and an air outlet 1242 are provided in the second electrode 124. The air inlet channel 1241 is communicated between the outside atmosphere and the air outlet 1242, and the air outlet 1242 is in communication with the first opening 1221. In this way, the external air flows to the air outlet 1242 through the air inlet channel 1241, and sequentially flows from the air outlet 1242 to the first opening 1221, the second opening 1121 and the first air outlet channel 14.

A plurality of the air outlets 1242 spaced apart are arranged in the circumferential direction of the second electrode 124 to ensure smooth airflow.

In an embodiment, the protrusion is arranged on the base body 121. The electrode holder 12 further includes a sealing member 125 (referring to FIG. 3). An end of the sealing member 125 in the axial direction abuts against the first electrode 122, and the other end abuts against both the protrusion and the first mounting ring 112. In addition, the sealing member 125 has an inner surface abutting against the base body 121, and an outer surface abutting against the inner wall of the first mounting ring 112 (referring to FIG. 6). In this way, the first mounting ring 112 can support the electrode holder 12 in the axial direction, to prevent the electrode holder 12 from being separated from the first mounting ring 112 under the action of gravity. In addition, the sealing member 125 can prevent air from leaking to the outside from between the base body 121 and the first mounting ring 112.

Referring to FIG. 6, the vaporizer 10 further includes a vaporization assembly 15, and the vaporization assembly 15 is detachably arranged at an end of the first body 111 that is away from the electrode holder 12. In this way, after smoking is completed, only the used vaporization assembly 15 needs to be detached, and after being cleaned, other assemblies can be reused with a new vaporization assembly 15, thereby reducing the cost and resources.

Referring to FIG. 8, the vaporization assembly 15 includes a vaporization core 151, a third electrode 152 and a fourth electrode 153. The vaporization core 151 is detachably arranged at an end of the first body 111 that is away from the electrode holder 12; the third electrode 152 and the fourth electrode 153 are both arranged at an end of the vaporization core 151 that is close to the electrode holder 12; the third electrode 152 abuts against the second electrode 124, and the fourth electrode 153 abuts against the first electrode 122. In this way, the electrode holder 12 plays the role of supporting and positioning the vaporization assembly 15.

A liquid storage tank is arranged in the vaporization core 151, and a second air outlet channel 16 (referring to FIG. 6) in communication with the first air outlet channel 14 is formed between the outer wall of the vaporization core 151 and the first housing 11. At least part of the outer surface of the vaporization core 151 forms a vaporization surface 154 (referring to FIG. 8), and the vaporization surface 154 is in communication with the second air outlet channel 16. Specifically, the vaporization assembly 15 further includes a heating body. The heating body is placed in the vaporization core 151; the third electrode 152 and the fourth electrode 153 are electrically connected to the heating body; the heating body generates heat to vaporize an aerosol generation substrate located in the liquid storage tank, and the aerosol flows from the vaporization surface 154 to the second air outlet channel 16 for discharge.

Specifically, referring to FIG. 9, the vaporization core 151 includes a cylindrical body 1511 and a sealing cover 1512. The sealing cover 1512 closes an end of the cylindrical body 1511 that is close to the electrode holder 12, and defines a liquid storage tank together with the cylindrical body 1511. The third electrode 152 and the fourth electrode 153 are arranged on the sealing cover 1512, and a surface of the sealing cover 1512 facing the electrode holder 12 forms the vaporization surface 154. The gas generated by vaporization and the external air sequentially flow to the outside through the first opening 1221, the second opening 1121, the first air outlet channel 14 and the second air outlet channel 16.

In an embodiment, the cylindrical body 1511 and the sealing cover 1512 are both sintered by ceramic. When the surface of the sealing cover 1512 facing the electrode holder 12 forms the vaporization surface 154, the outer surface of the cylindrical body 1511 is made into a dense layer or a glaze layer. It should be understood that, both the outer surface at an end of the cylindrical body 1511 that is close to the sealing cover 1512 and the outer surface of the sealing cover 1512 can serve as the vaporization surface 154. In this case, the outer surface at an end of the cylindrical body 1511 that is away from the sealing cover 1512 may be made into a dense layer or a glaze layer. In other embodiments, the cylindrical body 1511 may alternatively be made of a liquid-impermeable material, and the sealing cover 1512 may be made of porous ceramics. The cylindrical body 1511 and the sealing cover 1512 are jointly sintered, which is not limited herein.

Referring to FIG. 8, the third electrode 152 is dot-shaped, and the fourth electrode 153 is arranged surrounding the third electrode 152. Specifically, the fourth electrode 153 is annular. In this way, the electrical connection effect can be ensured without requiring the alignment between the second electrode 124 and the third electrode 152 or the alignment between the first electrode 122 and the fourth electrode 153.

Further, the first electrode 122 includes at least two contact portions 1222 that are in contact with the fourth electrode 153 (referring to FIG. 3). That is, in the specific embodiment, an end of the first electrode 122 that is close to the fourth electrode 153 has a gap that is in communication with the first opening 1221. In this way, the first electrode 122 is divided into at least two contact portions 1222 spaced apart by the first opening 1221. Certainly, in some other embodiments, the arrangement manner of the first electrode 122 is not limited thereto.

An end of the cylindrical body 1511 that is away from the sealing cover 1512 is provided with a liquid storage port in communication with the liquid storage tank. The vaporization assembly 15 further includes a vaporization plug 155, the vaporization plug 155 is partially plugged in the liquid storage port, and an exhaust channel 156 (referring to FIG. 9) communicated between the second air outlet channel 16 and the outside is provided on a portion of the vaporization plug 155 protruding from the liquid storage port. In this way, the vaporization plug 155 can not only close the liquid storage port, but also serve as a channel for the air to flow out of the vaporizer 10.

Further, referring to FIG. 1 and FIG. 2, the electronic vaporization device 100 further includes a suction nozzle 20. The suction nozzle 20 is mounted at an end of the first body 111 that is away from the electrode holder 12, the vaporization assembly 15 is located between the electrode holder 12 and the suction nozzle 20, and the suction nozzle 20 is in communication with the exhaust channel 156. In this way, when the user sucks through the suction nozzle 20, the air sequentially enters the suction nozzle 20 through the air inlet channel 1241, the first opening 1221, the second opening 1121, the first air outlet channel 14, the second air outlet channel 16 and the exhaust channel 156 for the user to suck.

The electronic vaporization device 100 further includes a power supply assembly 30, and the power supply assembly 30 includes a second housing 31 and a power supply 32. The second housing 31 includes a second body 311 and a second mounting ring 312. The power supply 32 and the second mounting ring 312 are both arranged in the second body 311. An end of the base body 121 of the electrode holder 12 facing the second mounting ring 312 is provided with a thread-connected portion 1211, and the thread-connected portion 1211 is in threaded connection with the second mounting ring 312. Specifically, the second mounting ring 312 is made of a conductive material, and the base body 121 is connected to the power supply 32 through the second mounting ring 312. The power supply assembly 30 further includes a second insulating member 33 and a conductive member 34. The second insulating member 33 is arranged between the conductive member 34 and the second mounting ring 312 to block the electrical connection between the second mounting ring 312 and the conductive member 34. The conductive member 34 is connected to the second electrode 124.

Another embodiment of the present application further provides the vaporizer 10 included in the electronic vaporization device 100. In the vaporizer 10, the electrode holder 12 is matched with the first housing 11 through the first matching portion 131 and the second matching portion 132, and relative positions of the electrode holder 12 and the first housing 11 in the circumferential direction of the vaporizer 132 do not change easily. A position of the electrode arranged on the electrode holder 12 does not change easily, the vaporization assembly 15 is kept connected to a power supply 32 through the electrode at all times, and positions of other components that are in contact with the electrode holder 12 do not change easily, to ensure that various components in the vaporizer 10 closely match with each other, thereby improving the product yield.

The vaporizer 10 and the electronic vaporization device 100 provided in this embodiment have the following beneficial effects:

1. The first matching portion 131 is matched with the second matching portion 132 to limit the mutual rotation between the electrode holder 12 and the first housing 11 in the circumferential direction of the vaporizer 10, and relative positions of the electrode holder 12 and the first housing 11 in the circumferential direction of the vaporizer 10 do not change easily. A position of the electrode arranged on the electrode holder 12 does not change easily, the vaporization assembly 15 is kept connected to a power supply 32 through the electrode at all times, and positions of other components that are in contact with the electrode holder 12 do not change easily, to ensure that various components in the vaporizer 10 closely match with each other, thereby improving the product yield.

2. Both the protrusion as the first matching portion 131 and the groove as the second matching portion 132 extend in the axial direction of the vaporizer 10, so that the electrode holder 12 can be easily detached from the first housing 11 in the axial direction.

3. A width of the first opening 1221 is greater than a width of the second opening 1121. In this way, during mounting of the electrode holder 12, communication between the second opening 1121 and the second opening 1121 can be ensured without requiring precise alignment in the circumferential direction, so as to ensure smooth airflow.

4. The vaporization assembly 15 is detachably assembled in the first housing 11, and during replacement of the vaporizer 10, only the vaporization assembly 15 needs to be replaced, so that the cost is saved and waste of resources is avoided.

5. The third electrode 152 is dot-shaped, and the fourth electrode 153 is arranged surrounding the third electrode 152. The electrical connection effect can be ensured without requiring alignment between the second electrode 124 and the third electrode 152 or between the first electrode 122 and the fourth electrode 153.

The technical features in the above embodiments may be randomly combined. For concise description, not all possible combinations of the technical features in the embodiment are described. However, provided that combinations of the technical features do not conflict with each other, the combinations of the technical features are considered as falling within the scope recorded in this specification.

While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive. It will be understood that changes and modifications may be made by those of ordinary skill within the scope of the following claims. In particular, the present invention covers further embodiments with any combination of features from different embodiments described above and below. Additionally, statements made herein characterizing the invention refer to an embodiment of the invention and not necessarily all embodiments.

The terms used in the claims should be construed to have the broadest reasonable interpretation consistent with the foregoing description. For example, the use of the article “a” or “the” in introducing an element should not be interpreted as being exclusive of a plurality of elements. Likewise, the recitation of “or” should be interpreted as being inclusive, such that the recitation of “A or B” is not exclusive of “A and B,” unless it is clear from the context or the foregoing description that only one of A and B is intended. Further, the recitation of “at least one of A, B and C” should be interpreted as one or more of a group of elements consisting of A, B and C, and should not be interpreted as requiring at least one of each of the listed elements A, B and C, regardless of whether A, B and C are related as categories or otherwise. Moreover, the recitation of “A, B and/or C” or “at least one of A, B or C” should be interpreted as including any singular entity from the listed elements, e.g., A, any subset from the listed elements, e.g., A and B, or the entire list of elements A, B and C.
