[0033] Specifically, please refer to Figure 2 , Figure 3 and Figure 4The shell 11 is a hollow container with two open ends. The shell 11 can be cylindrical or cuboid. The shell 11 is sleeved on the outer periphery of the support 13. The support 13 includes a bottom wall 131. The shell 11 and the bottom wall 131 jointly form a containing cavity 111. The shell 11 can be made of plastic, including but not limited to PC (polycarbonate), ABS (acrylonitrile-butadiene-styrene copolymer), epoxy resin, etc. Of course, the shell 11 can also be made of metal, including stainless steel, copper or aluminum alloy, etc.

The support 13 can be made of plastic, including but not limited to PC (polycarbonate), ABS (acrylonitrile-butadiene-styrene copolymer), epoxy resin, etc.

[0035] In other embodiments, the shell 11 can also be a hollow container with one open end. The bottom wall 131 is fixedly connected with the side wall of the shell 11. The first partition plate 132 and the second partition plate 133 are respectively connected to the inner wall of the shell 11. That is, the shell 11, the first partition plate 132 and the second partition plate 133 are integrally connected.

[0036] Further, the first partition plate 132 and the second partition plate 133 divide the containing cavity 111 and form a first containing cavity 1111, a second containing cavity 1112 and a third containing cavity 1113. The first partition plate 132, the second partition plate 133 and part of the shell 11 enclose the first containing cavity 1111.

The opening and closing piece 12 is located at the first opening 1321. It can be understood that the shape of the opening and closing piece 12 should be consistent with the shape of the first opening 1321, so as to open or close the first opening 1321.

[0038] The material of the opening and closing piece 12 can be silica gel, rubber or silicone rubber. Of course, the material of the opening and closing piece 12 can also be plastic, including but not limited to PC (polycarbonate), ABS (acrylonitrile-butadiene-styrene copolymer), epoxy resin, etc. The opening and closing piece 12 can be made of a block material by cutting.

[0039] Please refer to Figure 1 , Figure 2 and Figure 4The electronic atomizer 100 further comprises an atomization assembly 20, which is at least partially accommodated in the third accommodating cavity 1113 and connected with the shell 11 and the second partition plate 133. In the embodiment, the first air inlet hole 112 can be located on the shell 11 corresponding to the connection between the atomization assembly 20 and the second partition plate 133, and the second partition plate 133 is provided with a flow guide channel 1332 and a second opening 1331, so that the external air can flow into the first accommodating cavity 1111 through the first air inlet hole 112, the flow guide channel 1332 and the second opening 1331.

[0040] In other embodiments, the first air inlet hole 112 can also be located on the shell 11 surrounding the first accommodating cavity 1111, and the number of the first air inlet hole 112 is not limited.

[0041] The second air inlet hole 113 can be located on the shell 11 corresponding to the second accommodating cavity 1112, and can also be located on the bottom wall 131, and the number of the second air inlet hole 113 is not limited. In the embodiment, the second air inlet hole 113 can also be a charging interface hole of the electronic atomizer 100; in other embodiments, the second air inlet hole 113 and the charging interface hole can also be separately arranged.

[0042] Further, the design size of the second air inlet hole 113 should be greater than that of the first air inlet hole 112, so that when the air in the second accommodating cavity 1112 flows into the first accommodating cavity 1111, the external air can also flow into the second accommodating cavity 1112 through the second air inlet hole 113 in time, so that the air pressure in the second accommodating cavity 1112 is always kept at a normal pressure.

[0043] When the user uses the electronic atomizer 100, the gas in the electronic atomizer 100 can be sucked by the atomization assembly 20, and the air flow in the air inlet assembly 10 is generated. Specifically, the gas in the first accommodating cavity 1111 flows into the atomization assembly 20 through the second opening 1331, so that the first accommodating cavity 1111 forms a first air pressure, and the first air pressure should be a negative pressure less than the normal pressure. The external air can flow into the first accommodating cavity 1111 through the first air inlet hole 112 and / or the first opening 1321, so that the first air pressure is balanced to be equal to the normal pressure; when the external air flows into the first accommodating cavity 1111 through the first opening 1321, the opening and closing piece 12 should be in an open state to open the first opening 1321.

[0044] The application sets the opening and closing member 12 between the first containing cavity 1111 with the first air inlet hole 112 and the second containing cavity 1112 with the second air inlet hole 113, and when the gas in the first containing cavity 1111 flows, the first air pressure is generated in the first containing cavity 1111, the opening size of the opening and closing member can be adjusted according to the difference between the first air pressure and the normal pressure, the air in the second containing cavity 1112 can flow into the first containing cavity 1111, so that the first air pressure is equal to the normal pressure; when the user takes a small mouthful of air while using the electronic atomizer 100, the first containing cavity 1111 can take in air through the first air inlet hole 112 to start the electronic atomizer 100 to work, when the user takes a large mouthful of air, the opening and closing member 12 is opened to control the air flow through a larger air flow, so that the user does not feel choking or blocking; and the opening and closing member 12 does not affect the start of the sensor 14 in the process of adjusting the opening size.

[0045] In an embodiment, the air inlet assembly 10 includes a first state, in which the first containing cavity 1111 takes in air through the first air inlet hole 112 to make the first air pressure equal to the normal pressure.

[0046] Specifically, before the first state, the gas in the first containing cavity 1111 flows into the atomizing assembly 20 through the second opening 1331 to make the first containing cavity 1111 form the first air pressure; in the first state, because the first air pressure is negative pressure, the external air flows into the first containing cavity 1111 under the influence of the pressure difference through the first air inlet hole 112, at this time, the first air pressure can be equal to the normal pressure.

[0047] Further, after the first air pressure is equal to the normal pressure, the air pressures in the first containing cavity 1111 and the second containing cavity 1112 are also in a balanced state, and the opening and closing member 12 is in a closed state.

[0048] Through the effect that the first air pressure is equal to the normal pressure when the first air inlet hole 112 takes in air in the first state, when the user takes a small mouthful of air while using the electronic atomizer 100, the electronic atomizer 100 can also be quickly started and worked after the first containing cavity 1111 generates a small air flow.

[0049] In an embodiment, the air inlet assembly 10 further includes a second state, in which the first containing cavity 1111 takes in air through the first air inlet hole 112, and at the same time, the opening of the opening and closing member 12 is opened, and the air in the second containing cavity 1112 flows into the first containing cavity 1111 through the second air inlet hole 113 through the opening of the opening and closing member 12, so that the first air pressure is equal to the normal pressure.

[0050] Specifically, before the second state, the gas in the first accommodating cavity 1111 flows into the atomization assembly 20 through the second opening 1331, so that the first accommodating cavity 1111 forms the first air pressure; in the second state, because the first air pressure is negative pressure, the opening of the opening and closing piece 12 is opened, and the external air flows into the first accommodating cavity 1111 through the first air inlet hole 112 and the first opening 1321 under the influence of the pressure difference, at this time, the first air pressure can be equal to the normal pressure.

[0051] Further, when the air inlet assembly 10 reaches the first state, the air in the first accommodating cavity 1111 continues to flow out through the second opening 1331, and when the air flowing in through the first air inlet hole 112 cannot balance the first air pressure to the normal pressure, the opening of the opening and closing piece 12 is opened, and the air in the second accommodating cavity 1112 flows into the first accommodating cavity 1111, so that the air inlet assembly 10 reaches the second state.

[0052] By flowing air into the first air inlet hole 112 and the opening of the opening and closing piece 12 at the same time in the second state, the effect of making the first air pressure equal to the normal pressure can be achieved, so that when the user takes a big mouthful of air using the electronic atomizer 100, the opening and closing piece 12 can be opened to make more air flow into the first accommodating cavity 1111 to supplement the air in the first accommodating cavity 1111, and the user will not feel suffocated or blocked due to the continuous negative pressure.

[0053] In one embodiment, please refer to Figure 5 The opening and closing piece 12 includes a fixed part 121 and a sealing part 122, the sealing part 122 is connected with the fixed part 121, the fixed part 121 is connected with the inner wall of the first opening 1321, and the sealing part 122 has elasticity to close or conduct the first opening 1321.

[0054] Specifically, the sealing part 122 is a sheet-shaped elastic body with a thickness smaller than that of the fixed part 121, and the sealing part 122 is at least partially connected with the fixed part 121. When a pressure difference is generated between the first accommodating cavity 1111 and the second accommodating cavity 1112, the sealing part 122 can be elastically deformed to conduct the first opening 1321, so that the pressures of the first accommodating cavity 1111 and the second accommodating cavity 1112 are in a balanced state. Moreover, the size of the elastic deformation of the sealing part 122 changes with the size of the pressure difference between the first accommodating cavity 1111 and the second accommodating cavity 1112, so that the volume of air flowing from the second accommodating cavity 1112 into the first accommodating cavity 1111 through the first opening 1321 can be controlled.

[0055] In other embodiments, please refer to Figure 11The sealing portion 122 can be a half of a circle connected with the fixed portion 121. In a normal pressure state, the end of the sealing portion 122 away from the fixed portion 121 is connected with the inner wall of the first opening 1321, so as to close the first opening 1321. In a second state of the air inlet assembly, the end of the sealing portion 122 away from the fixed portion 121 can be elastically deformed into the first accommodating cavity 1111 under the influence of the pressure difference, so as to open the first opening 1321.

[0056] The fixed portion 121 can be arranged to fix the opening and closing member 12 on the first partition plate 132. The elastic sealing portion 122 can be elastically deformed when the pressure difference between the first accommodating cavity 1111 and the second accommodating cavity 1112 is generated. Thus, the opening and closing member 12 can control the degree of elastic deformation of the sealing portion 122 according to the size of the pressure difference, and further adjust the size of the opening to control the size of the air flow through the first opening 1321.

[0057] In one embodiment, referring to Figure 5 and Figure 6 The sealing portion 122 includes a plurality of blades 1221 arranged in sequence. The plurality of blades 1221 are closed to close the first opening 1321. The plurality of blades 1221 are unfolded to open the first opening 1321.

[0058] Specifically, when the first opening 1321 is circular, the plurality of blades 1221 arranged in sequence can be pieces with inconsistent shapes. The fixed portion 121 can be a circular arc extending in a ring direction. The outer periphery of the fixed portion 121 is connected with part of the inner wall of the first opening 1321. At least part of the plurality of blades 1221 is connected with the inner periphery of the fixed portion 121. When the plurality of blades 1221 are closed, the shape formed by the plurality of blades 1221 should be consistent with the shape of the first opening 1321.

[0059] When the first air pressure is equal to the normal pressure, the plurality of blades 1221 are closed. When the first air pressure is less than the normal pressure and the air inlet assembly 10 is in the second state, the plurality of blades 1221 are elastically deformed under the influence of the pressure difference. The plurality of blades 1221 are unfolded from the end away from the fixed portion 121, so as to open the first opening 1321.

[0060] In other embodiments, referring to Figure 9 When the first opening 1321 is square, polygonal or elliptical, the fixed portion 121 can be a polygon or arc extending in a ring direction and consistent with part of the shape of the first opening 1321. At least part of the plurality of blades 1221 is connected with the inner periphery of the fixed portion 121. The end away from the fixed portion 121 can close or open the first opening 1321 by closing or unfolding.

[0061] In other embodiments, referring to Figure 10, the fixed part 121 can also be a straight bar extending transversely, the fixed part 121 is placed in the first opening 1321, the two ends of the fixed part 121 are connected with the inner wall of the first opening 1321, and the shape of the fixed part 121 can be a cylindrical straight bar or a square cylindrical straight bar. When the first opening 1321 is circular, the sealing part 122 can be two semicircular blades 1221, and one side of the blade 1221 is connected to the side of the fixed part 121. In the second state, the blade 1221 can be elastically deformed around the fixed part 121, that is, the two blades 1221 are folded towards each other and form a "V" shape to open the first opening 1321.

[0062] Further, when the first opening 1321 is square or polygonal, the sealing part 122 is two polygonal blades 1221; when the first opening 1321 is elliptical, the sealing part 122 is two fan-shaped blades 1221. It can be understood that the shape formed by the two polygonal blades 1221 should be consistent with the shape of the first opening 1321, so as to close the first opening 1321.

[0063] By setting the sealing part 122 as a plurality of blades 1221, sealing parts 122 with different arrangement shapes can be made, so that the opening and closing part 12 can be applied to different air inlet assemblies 10, and different blade 1221 closing and opening modes can be designed to further control the air flow through the first opening 1321.

[0064] In an embodiment, please refer to Figure 5 and Figure 6 , the first opening 1321 is circular, the fixed part 121 is annular, and the plurality of blades 1221 are fan-shaped, and the tip of each blade 1221 away from the fixed part 121 is located at the center of the annular fixed part 121.

[0065] Specifically, the outer periphery of the fixed part 121 is connected with the inner wall of the first opening 1321, and the fixed part 121 can be fixed on the first opening 1321 by friction. Of course, in other embodiments, the fixed part 121 and the inner wall of the first opening 1321 can be threadedly connected, or can be connected by a matching part.

[0066] The sealing part 122 is a circular surface, the sealing part 122 can be cut into a plurality of blades 1221, the plurality of blades 1221 can be equal fan-shaped with the same size, and the circular arc end of the plurality of blades 1221 is connected with the inner periphery of the fixed part 121.

[0067] Of course, in other embodiments, please refer to Figure 7 , the plurality of blades 1221 can be fan-shaped with different sizes, and the tip of each blade 1221 away from the fixed part 121 can be located at any point in the annular fixed part 121.

[0068] When the first air pressure is equal to the normal pressure, the plurality of blades 1221 are closed; when the first air pressure is less than the normal pressure and the air inlet assembly 10 is in the second state, the plurality of blades 1221 are elastically deformed under the influence of the pressure difference and are unfolded from the common pointed center of the tips of the plurality of blades 1221, so as to open the first opening 1321.

[0069] In other embodiments, referring to Figure 8 , the shape of the first opening 1321 can also be square, the fixed part 121 is square ring-shaped, the sealing part 122 is one-sided shaped, the plurality of blades 1221 are all triangular, and the tip of each blade 1221 away from the fixed part 121 is located at the center of the ring-shaped fixed part 121.

[0070] Of course, the shape of the first opening 1321 can also be polygonal or oval, and it can be understood that the cross-sectional shape of the fixed part 121 should be consistent with the shape of the first opening 1321, and the plurality of blades 1221 can be closed or unfolded by elastic deformation.

[0071] By designing the fixed part 121 to be ring-shaped and the plurality of blades 1221 to be fan-shaped, it is beneficial for the blades 1221 to be unfolded to maximize the area of the opening, and it is also convenient for processing the opening and closing member 12.

[0072] In one embodiment, referring to Figure 5 and Figure 6 , the sealing part 122 includes a first surface 1222 facing the first accommodating cavity 1111, and a curved groove 1223 is formed on the first surface 1222 near the fixed part 121 in the ring direction.

[0073] Specifically, the curved groove 1223 can be a ring-shaped groove formed on the first surface 1222, and the cross section of the curved groove 1223 can be triangular or semicircular. When the first air pressure is less than the normal pressure and the air inlet assembly 10 is in the second state, the plurality of blades 1221 can be elastically deformed around the curved groove 1223 under the influence of the pressure difference.

[0074] Further, the shape of the curved groove 1223 can be consistent with the shape of the fixed part 121. It can be understood that when the fixed part 121 is a closed ring, at least one end of the plurality of blades 1221 is connected to the fixed part 121, and the curved groove 1223 is located on the blade 1221 and close to the end of the fixed part 121, so that the blade 1221 can be elastically deformed around the curved groove 1223 while being connected to the fixed part 121, so as to unfold and open the first opening 1321.

[0075] In other embodiments, referring to Figure 10When the fixed part 121 is a straight rod extending in the transverse direction, the plurality of blades 1221 are respectively located on both sides of the fixed part 121, and the curved groove 1223 is a straight-line groove consistent with the extension direction of the fixed part 121, and the blade 1221 can be elastically deformed and unfolded around the groove.
