[0020] The second pipe member further includes a protrusion, which is protruding from the inner wall of the end wall. The protrusion is formed with a protruding slope, and the protruding slope is configured to guide the fluid to flow toward the second air inlet.

[0021] In some embodiments, the main body and the first pipe are an integrally formed structure; and / or,

[0022] The filter assembly further includes a liquid absorbing component disposed outside the main body, and the liquid absorbing component is located at the first air outlet.

[0028] Beneficial effects of the utility model:

[0029] The filter assembly of the utility model is used to communicate with the atomizer assembly of an electronic cigarette. The filter assembly is configured such that one end of a first tube is connected to the first air outlet, and the other end of the first tube extends to the middle area of ​​the filter cavity and is provided with a second air outlet; at the same time, one end of a second tube is connected to the first air inlet, and the other end of the second tube extends to the middle area of ​​the filter cavity and is provided with a second air inlet, thereby extending the second air outlet and the second air inlet to the middle area of ​​the filter cavity. With this design, when a small amount of filtered liquid is contained in the filter cavity, it is difficult for the filtered liquid to submerge the second air outlet or the second air inlet, and thus it is difficult for the filtered liquid to leak from the second air outlet or the second air inlet, thereby achieving a certain leak-proof effect.

[0030] At the same time, since the air guide hood is arranged in the filter cavity, the air guide hood covers the second pipe fitting, and a third air inlet is opened at one end of the air guide hood close to the second air inlet, a guide gap is formed between the air guide hood and the second pipe fitting to connect the second air inlet and the third air inlet, which actually extends and changes the conduction path between the second air inlet and the filter cavity, and makes the gas entering through the second air inlet must first flow through the guide gap to the third air inlet before entering the filter cavity through the third air inlet, and then flow into the second air outlet through the filter cavity, flow to the first air outlet through the second air outlet, and finally flow out of the filter assembly. This design structure is conducive to the gas flowing into the filter assembly from the first air inlet, and the gas flowing out of the filter assembly from the first air outlet is cleaned and filtered by the filtered liquid.

[0031] Specifically, when the filter assembly is generally upright, that is, the first air inlet is located below the bottom and the first air outlet is located above the top, the filtered liquid submerges the third air inlet, and the gas is cleaned by the filtered liquid.

[0032] In summary, the filter assembly has a good gas filtering effect and is not prone to leakage when placed upright, sideways, or upside down. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Electronic cigarettes usually include a tobacco material holding portion for containing tobacco material. In order to improve the smoking experience, the tobacco material holding portion is connected to the external atmosphere and is connected to a tobacco pipe containing filtered liquid through a ventilation pipe. The other end of the tobacco pipe forms a mouthpiece. When the user uses it, the gas passes through the tobacco material holding portion, the filtered liquid in the tobacco pipe, and the mouthpiece of the tobacco pipe in sequence and enters the user's mouth. Existing electronic cigarettes have the problem of easy leakage.

[0054] To this end, an embodiment of the present application provides a filter assembly 100, referring to Figure 1-7 The filter assembly 100 is used to communicate with the atomizer assembly 200 of the electronic cigarette. The filter assembly 100 includes a main body 110, a first tube 120, a second tube 130 and an air guide cover 140. Among them, the main body 110 is provided with a first air outlet 111, a filter cavity 112 and a first air inlet 113; one end of the first pipe fitting 120 is connected to the first air outlet 111, and the other end of the first pipe fitting 120 extends to the middle area of ​​the filter cavity 112 and is provided with a second air outlet 121; one end of the second pipe fitting 130 is connected to the first air inlet 113, and the other end of the second pipe fitting 130 extends to the middle area of ​​the filter cavity 112 and is provided with a second air inlet 131; the air guide cover 140 is arranged in the filter cavity 112 and covers the second pipe fitting 130, and the air guide cover 140 is provided with a third air inlet 141 at one end away from the second air inlet 131, and a guide gap 142 is formed between the air guide cover 140 and the second pipe fitting 130 to connect the second air inlet 131 and the third air inlet 141.

[0055] refer to Figure 1-7The filter assembly 100 can accommodate filtered liquid through the filter cavity 112 of the main body 110. The filtered liquid can be water, etc.; it is achieved by connecting one end of the first tube 120 to the first air outlet 111, and the other end of the first tube 120 extends to the middle area of ​​the filter cavity 112 and opens a second air outlet 121; at the same time, one end of the second tube 130 is connected to the first air inlet 113, and the other end of the second tube 130 extends to the middle area of ​​the filter cavity 112 and opens a second air inlet 131, so that the second air outlet 121 and the second air inlet 131 extend to the middle area of ​​the filter cavity 112. When a small amount of filtered liquid is contained in the filter cavity 112 with this design, it is difficult for the filtered liquid to submerge the second air outlet 121 or the second air inlet 131, and thus it is difficult for the filtered liquid to leak from the second air outlet 121 or the second air inlet 131, which has a certain leak-proof effect.

[0056] At the same time, since the air guide cover 140 is arranged in the filter cavity 112, the air guide cover 140 covers the second pipe 130, and the air guide cover 140 is provided with a third air inlet 141 at one end away from the second air inlet 131, a guide gap 142 is formed between the air guide cover 140 and the second pipe 130 to connect the second air inlet 131 and the third air inlet 141. In fact, the conduction path between the second air inlet 131 and the filter cavity 112 is extended and changed, and the gas entering through the second air inlet 131 must first pass through the The air flows through the guide gap 142 to the third air inlet 141, and then enters the filter cavity 112 through the third air inlet 141, and then flows into the second air outlet 121 through the filter cavity 112, flows to the first air outlet 111 through the second air outlet 121, and finally flows out of the filter assembly 100. This design structure is conducive to the gas flowing into the filter assembly 100 from the first air inlet 113, and fully contacting the filtered liquid in the filter assembly 100. Therefore, the gas flowing out of the filter assembly 100 from the first air outlet 111 is cleaned and filtered by the filtered liquid.

[0057] Specifically, when the filter assembly 100 is generally upright, that is, the first air inlet 113 is located below the bottom and the first air outlet 111 is located above the top, the filtered liquid submerges the third air inlet 141, and the gas is cleaned by the filtered liquid.

[0058] In summary, the filter assembly 100 provided in the embodiment of the present application has a good gas filtering effect and is not prone to leakage when placed upright, sideways, or upside down, and has a leak-proof effect.

[0059] Explanatoryally, the middle area of ​​the filter chamber 112 can be understood to be roughly located in the middle section of the filter chamber 112 along the height direction of the filter chamber 112, that is, from the top to the bottom direction; at the same time, along the length and width directions of the filter chamber 112, it is roughly located in the middle section of the filter chamber 112.

[0060] Further, refer to Figure 1-7 In some embodiments, the second pipe 130 includes a side wall portion and an end wall portion. The side wall portion forms a flow channel connected to the first air inlet 113; the end wall portion blocks the end of the flow channel away from the first air inlet 113, and the second air inlet 131 is opened in the side wall portion and / or the end wall portion, thereby extending and arranging the second air inlet 131 in the middle area of ​​the filter cavity 112, so that it is not easily submerged by the filtrate in the filter cavity 112 and causes leakage; in this embodiment, the second air inlet 131 is opened in the side wall portion. The minimum distance H between the top of the inner cavity of the air guide cover 140 and the end wall portion is not less than half of the outer diameter L of the second pipe 130, and the top of the inner cavity is the portion of the air guide cover 140 facing the end wall portion along the extension direction of the second pipe 130. This design allows the top of the inner cavity of the air guide 140 to have a larger volume to accommodate the residual filtrate when the filter assembly 100 is inverted, thereby reducing the immersion of the residual filtrate in the second tube 130 and preventing it from immersing the second air inlet 131. In some specific embodiments, the volume of the guide gap 142 can be designed to be as small as possible, thereby reducing the amount of filtrate leaking from the second air inlet 131 when the filter assembly 100 is inverted or vibrating.

[0061] In other embodiments, reference Figure 1-7 , along the direction from the bottom to the top of filter assembly 100, the volume of guide gap 142 includes a first portion located above second air inlet 131 and a second portion located below second air inlet 131. The volume of the second portion is no more than three times that of the first portion. This design allows the filtered liquid to be contained within the second portion to a depth of one-third of its height, minimizing leakage of filtered liquid from second air inlet 131 when filter assembly 100 is inverted or vibrated.

[0062] Specifically, refer to Figure 1-7 In some embodiments, the main body 110 may include a filter housing having dual top and bottom openings, a top sealing cover covering the top opening, a bottom sealing cover covering the bottom opening, a first pipe 120 inserted through the top sealing cover, a second sealing member inserted through the bottom sealing cover, and an air guide 140 covering one end of the second pipe 130 extending into the filter cavity 112. Of course, in some embodiments, the main body 110 and the first pipe 120 may also be an integrally molded structure to reduce the number of parts and simplify the assembly process. Similarly, in some embodiments, the second pipe 130 and the bottom sealing cover may also be an integral structure.

[0063] In some embodiments, reference Figure 1-7The filter assembly 100 further includes a liquid absorbent member 150 disposed on the exterior of the main body 110, and the liquid absorbent member 150 is located at the first air outlet 111. Specifically, a receiving groove is recessed on the exterior of the main body 110, and the liquid absorbent member 150 is embedded in the receiving groove. The receiving groove can be an annular groove designed around the first air outlet 111 or a groove body of any other shape. Of course, the liquid absorbent member 150 can be a breathable absorbent cotton that covers the first air outlet 111, or it can also not cover the first air outlet 111. The liquid absorbent member 150 can also be made of other materials with an adsorption effect, and there is no specific limitation.

[0064] Specifically, refer to Figure 1-7 In some embodiments, the main body 110 has a top wall and a bottom wall, the first air outlet 111 is opened on the top wall, the first air inlet 113 is opened on the bottom wall opposite to the first air outlet 111, the second pipe 130 extends toward the first air outlet 111, and the third air inlet 141 is opened at one end of the air guide cover 140 close to the bottom wall. The end of the air guide cover 140 close to the second air inlet 131 is a closed end, and the projection of the closed end on a plane perpendicular to the axis of the second pipe 130 covers the projection of the second air outlet 121, so that the closed end can prevent the second air outlet 121 from directly facing the second air inlet 131.

[0065] In some embodiments, reference Figure 1-7 The air guide 140 includes a tube body 143 and a shielding portion 144. One end of the tube body 143 is connected to the inner wall of the filter cavity 112 and defines a third air inlet 141. The other end of the tube body 143 is sealed. The end of the second tube 130 extending into the filter cavity 112 is accommodated within the inner cavity of the tube body 143. The shielding portion 144 is connected to one end of the tube body 143. The projection of the shielding portion 144 on a plane perpendicular to the axis of the second tube 130 covers the projection of the second air outlet 121.

[0066] By optimizing the design of the air guide cover 140 to include a tube body 143 and a shielding portion 144, the tube body 143 can be made thinner while ensuring that the shielding portion 144 is sufficiently large. The thinner design of the tube body 143 helps to optimize and reduce the volume of the flow guide gap 142, while the sufficient size of the shielding portion 144 helps to block the flow of the filtered liquid. As a result, when the filter assembly 100 is tilted or inverted, the filtered liquid is less likely to enter the second air outlet 121 and cause leakage.

[0067] Specifically, refer to Figure 1-7In some embodiments, the shielding portion 144 is an umbrella-shaped structure, and the tube body 143 is a slender straight tube structure. The tube body 143 is sleeved on the outer periphery of the second tube 130. The shielding portion 144 is used to better guide the filtrate and prevent the filtrate from leaking. By designing the tube body 143 as a slender straight tube structure, a thinner size structure design of the tube body 143 can be achieved.

[0068] refer to Figure 1-7 In some embodiments, the outer periphery of the second pipe 130 is provided with a beveled convex portion 132, and the surface of the beveled convex portion 132 is formed with an inclined slope 1321, and the inclined slope 1321 is configured to guide the flow toward the third air inlet 141, thereby facilitating that when the filter assembly 100 is tilted, the filtered liquid contained in the guide gap 142 quickly flows out from the third air inlet 141, thereby reducing the residual filtered liquid in the guide gap 142.

[0069] In some embodiments, reference Figure 1-7 The second pipe member 130 includes an end wall portion and a side wall portion. The side wall portion forms a flow channel connected to the first air inlet 113. The end wall portion blocks the end of the flow channel away from the first air inlet 113. The second air inlet 131 is opened in the side wall portion and is located at a position where the side wall portion is adjacent to the end wall portion. This allows the second air inlet 131 to be arranged in the central area of ​​the filter cavity 112 while being opened as far as possible in the radial direction of the second pipe member 130. Of course, there can be multiple second air inlets 131, and the multiple second air inlets 131 can be arranged at intervals along the circumference of the second pipe member 130.

[0070] In some embodiments, reference Figure 1-7 The end wall of the second tube 130 has an inner wall located in the flow channel. The inner wall is located on one side of the second air inlet 131 and guides the flow toward the second air inlet 131, which is conducive to quickly guiding the filtered liquid that accidentally enters the second tube 130 when it is inverted to the guide gap 142.

[0071] refer to Figure 1-7 In some embodiments, the second pipe fitting 130 further includes a raised portion 133, which is protruded from the inner wall of the end wall portion. The raised portion 133 is formed with a raised inclined surface 1331, which is configured to guide the fluid to flow toward the second air inlet 131. The raised inclined surface 1331 serves to further guide the fluid, thereby minimizing the amount of residual filtrate that accidentally enters the second pipe fitting 130 when it is inverted.

[0072] In addition, reference Figure 1 and Figure 8-9Still other embodiments of the present application provide an electronic cigarette, comprising an atomizer assembly 200 and a filter assembly 100 provided according to any of the above embodiments. The atomizer assembly 200 includes a first air port 210, an atomizer chamber 220, and a second air port 230, which are sequentially connected. The atomizer chamber 220 is configured to accommodate the aerosol generated by the atomizer assembly 200. One of the first air outlet 111 and the first air inlet 113 of the filter assembly 100 is connected to the second air port 230. Specifically, the connection can be direct or indirect, such as through a connecting pipe, and the details will not be repeated here.

[0073] It should be noted that the reference Figure 8-9 The atomizer assembly 200 can use an existing atomizer structure for atomization, such as a heating type. Specifically, it can also include an atomizer outer shell 240, which can contain oil storage cotton 250, an atomizer core 260, etc. The atomizer core 260 can include an electric heating network, thereby generating an atomized aerosol through electric heating. Of course, other structures can also be used, which have a first air port 210, an atomization chamber 220, and a second air port 230 connected in sequence. The details are not repeated here.

[0074] In some embodiments, reference Figure 1 and Figure 8 The electronic cigarette also includes a mouthpiece 300, which is connected to the first air port 210, the first air outlet 111 is connected to the second air port 230, and the first air inlet 113 is connected to the external atmosphere. Thus, when inhaled through the mouthpiece 300, the air in the external environment can be filtered by the filter assembly 100. The filtered air flows into the atomizer assembly 200, and the aerosol is carried out from the first air port 210, thereby improving the taste.

[0075] Of course, in other embodiments, reference Figure 1 and Figure 9 The electronic cigarette also includes a mouthpiece 300, which is connected to the first air outlet 111, the first air inlet 113 is connected to the second air port 230, and the first air port 210 is connected to the external atmosphere. In this way, when the cigarette is inhaled through the mouthpiece 300, the aerosol generated by the atomization component 200 can be filtered through the filter component 100 to improve the taste. The specific ventilation path is that the external atmosphere enters the atomization component 200, and the aerosol is sucked into the filter component 100. After being filtered by the filtrate of the filter component 100, it enters the mouthpiece 300 through the first air outlet 111 for the user to inhale, thereby improving another different way to improve the taste.

[0076] In addition, reference Figure 8-9The electronic cigarette may further include an electronic cigarette housing 400, a battery 500, a PCB board 600, a microphone 700 for measuring gas flow, etc. The microphone 700 is disposed at the outlet of the second gas port 230 to detect the gas flow rate. The specific structure of this part can be adopted from existing ones and will not be described in detail.

[0077] Finally, it should be noted that the various technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
