DETAILED DESCRIPTION

[0032] In order to make the above objectives, features and advantages of the present application more clear and comprehensible, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many different ways other than the embodiments described herein, and one of ordinary skill in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments of the present application and are not intended to limit the present application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] In the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "fixing" and the like should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be internal communication of two elements or interaction relationship between two elements, unless otherwise explicitly limited. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] Reference should be made to Figures 1-6 As shown in the drawings, the present application provides an electronic atomizer 1, comprising a shell, a first liquid storage cavity 11 and a second liquid storage cavity 21 are arranged in the shell for storing liquid, wherein the second liquid storage cavity 21 is independent of the first liquid storage cavity 11, and is used for delivering liquid to the first liquid storage cavity 11, a liquid passage 120 is arranged between the first liquid storage cavity 11 or the first liquid storage cavity 11 and the second liquid storage cavity 21, the liquid passage 120 has an inner wall extending in the axial direction, at least part of the inner wall protrudes radially to form at least one flow guide part 121.

[0035] After the first liquid storage cavity 11 and the second liquid storage cavity 21 are communicated, the liquid aerosol-forming substrate in the second liquid storage cavity 21 can flow into the first liquid storage cavity 11 along the liquid passage 120, wherein the flow guide part 121 protrudes from the inner wall surface of the liquid passage 120. On the one hand, the flow guide part 121 can guide the flow of liquid, on the other hand, the user can vibrate the electronic atomizer 1, so that the liquid impacts the flow guide part 121 under the action of vibration, and the liquid surface tension is broken through the flow guide part 121, or the bubbles are eliminated, so that the liquid can flow smoothly to the first liquid storage cavity 11.

[0036] In some embodiments, specifically, the electronic atomizer 1 provided in this embodiment includes: a relatively independent first housing 10, a second housing 20, and a liquid channel 120. The first housing 10 defines a first liquid storage chamber 11 for storing liquid; the second housing 20 defines a second liquid storage chamber 21 for storing liquid; the liquid channel 120 has an axially extending first end and a second end, the first end being connected to the first housing 10 and communicating with the first liquid storage chamber 11, and the second end being connected to the second housing 20 and communicating with the second liquid storage chamber 21, and a guide portion 121 protruding from the inner wall of the liquid channel 120 is formed.

[0037] like Figure 4 As shown, one end of the first housing 10 is provided with an opening, and a sealing base 12 is installed at the opening. The sealing base 12 and the first housing 10 define a first liquid storage chamber 11, and the liquid channel 120 passes through the sealing base 12 and communicates with the first liquid storage chamber 11.

[0038] In some embodiments, the sealing base 12 has a first surface and a second surface within the first liquid storage cavity 11, with a liquid channel penetrating the first surface. In the extending direction of the liquid channel, the first surface is closer to the first liquid storage cavity 11 than the second surface.

[0039] The first housing 10 and the second housing 20 are detachably connected. For example... Figure 4 As shown, one side of the sealing base 12 is combined with the first housing 10 to form a first liquid storage chamber 11, and the other side of the sealing base 12 is combined with the first housing 10 to form an open receiving chamber 15. The second housing 20 can be inserted into the receiving chamber 15 at least partially and is connected to the first housing 10.

[0040] The thickness of the guide portion 121 gradually decreases from one end near the inner wall to the other. In some embodiments, the end of the guide portion 121 near the inner wall is defined as the proximal end, and the end of the guide portion 121 away from the inner wall and opposite to the proximal end is defined as the distal end. The thickness of the guide portion 121 gradually decreases from the proximal end to the distal end to form a blade at the distal end that can easily break bubbles. In some embodiments, the end of the guide portion 121 near the first liquid storage chamber 11 is defined as the proximal end, and the end of the guide portion 121 near the second liquid storage chamber 21 is defined as the distal end. The thickness of the guide portion 121 gradually decreases from the proximal end to the distal end to form a blade at the distal end that can easily break bubbles. Alternatively, the guide portion 121 has a first side surface and a second side surface that connect to the inner wall at the proximal end, and the first side surface and the second side surface connect at the distal end of the guide portion 121 to form a tip.

[0041] In some embodiments, at least a portion of the inner wall protrudes radially from multiple directions to form a plurality of guide portions 121. For example... Figure 3As shown, the liquid channel is a circular hole, and the inner wall of the liquid channel is annularly provided with a plurality of flow guide portions 121. When there is a gas bubble in the liquid supply chamber, the gas bubble will be blocked in the liquid channel 120 due to the aperture limitation of the liquid channel. Under the action of the liquid gravity, the gas bubble can be deformed in the liquid channel 120 under the limitation of the flow guide member, and the large gas bubble can be divided into small gas bubbles.

[0042] In one aspect, the electronic atomizer 1 further comprises an atomization assembly 30 for atomizing the aerosol-forming substrate to form an aerosol. The atomization assembly 30 sequentially penetrates the sealing base 12 and the first shell 10, and the atomization assembly 30 forms a suction nozzle 13 on the first shell 10 to communicate with the outside. Figure 2 As shown, the atomization assembly 30 is arranged side by side with the liquid channel 120, and the atomization assembly 30 is provided with a liquid inlet 31 that communicates with the first liquid storage chamber 11. The liquid inlet 31 is away from the first surface and close to the second surface. Figure 3 As shown, the sealing base 12 is provided with a mounting hole 122, one end of the atomization assembly 30 is fitted in the mounting hole 122, and the other end of the atomization assembly 30 is connected with the first shell 10 to define a suction nozzle 13 that communicates with the outside.

[0043] Referring to Figure 2 As shown, a height difference is formed between the liquid inlet end of the first liquid storage chamber 11 and the liquid outlet end that communicates with the liquid inlet 31, so as to avoid backflow of the aerosol-forming substrate into the first liquid storage chamber 11. For example, by inverting the electronic atomizer 1, the second shell 20 is located above the first shell 10, and under the action of the liquid gravity, the aerosol-forming substrate is guided to flow into the first liquid storage chamber 11 through the liquid channel. After completing the liquid injection, the electronic atomizer 1 is inverted again, and the second shell 20 is located below the first shell 10, so that the aerosol-forming substrate is accommodated in the liquid accumulation space formed by the connecting surface of the first surface and the second surface and the inner wall of the first shell 10.

[0044] On the other hand, the electronic atomizer 1 further comprises a movable member 14 that can be operated. The movable member 14 is arranged on the first shell 10 or the second shell 20. One end of the movable member 14 forms an area that can be pressed on the first shell 10 or the second shell 20, and the other end is located outside the first liquid storage chamber 11. One end of a spring 142 is connected with the rod 141, and the other end is connected with the first shell 10 or the second shell 20. The first liquid storage chamber 11 has a first position, and the second liquid storage chamber 21 has a second position. When the movable member 14 is operated, one end of the movable member 14 can be moved to the first position, or the second position, or a position between the first position and the second position.

[0045] As shown, Figures 5-6As shown, the moving part 14 comprises a rod 141 and a spring 142, the rod 141 is arranged on the first housing 10 or the second housing 20, wherein one end of the rod 141 forms a pressing area 140 capable of being pressed by a user on the first housing 10, and the other end is located outside the first liquid storage cavity 11, one end of the spring 142 abuts against the first housing 10, and the other end of the spring 142 is connected with the rod 141. The rod 141 has a first position capable of staying in the first liquid storage cavity 11, and the rod 141 has a second position capable of staying in the second liquid storage cavity 21, when the rod 141 is operated by the user, one end of the rod 141 can be moved to the first position, or the second position, or a position between the first position and the second position, for example, a position between the first liquid storage cavity 11 and the second liquid storage cavity 21.

[0046] It can be understood that when the rod 141 is pressed by the user, the other end of the rod 141 can extend into the first liquid storage cavity 11 or the second liquid storage cavity 21 from the first liquid storage cavity 11 or the second liquid storage cavity 21. Specifically, when the other end of the rod 141 extends into the first liquid storage cavity 11 or the second liquid storage cavity 21 from the first liquid storage cavity 11 or the second liquid storage cavity 21 after the rod 141 is pressed by the user, the rod 141 returns to the initial state under the elastic force of the spring 142 when the pressing force is released from the pressing area 140.

[0047] When the first liquid storage cavity 11 and the second liquid storage cavity 21 are communicated, the user can destroy the surface tension of the liquid in the second liquid storage cavity 21 for supplying the first liquid storage cavity 11 by pressing the rod 141, and the liquid aerosol-forming substrate in the second liquid storage cavity 21 can flow into the first liquid storage cavity 11 along the liquid channel 120, and further destroy the surface tension of the liquid by combining with the flow guide part 121 protruding from the inner wall of the liquid channel 120, so that the liquid can flow smoothly.

[0048] The above only describes some or preferred embodiments of the present application, neither the text nor the drawings can limit the scope of protection of the present application, any equivalent structural transformation made by using the contents of the present application and the drawings, or direct / indirect application in other related technical fields are included in the scope of protection of the present application.
