For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0053] The core idea of the embodiments of the present application is to disclose an atomizer, as shown in the figure, the atomizer comprises: a shell 11, having a containing cavity 112 with an open end 111; a separation support 2 is arranged in the containing cavity 112, and a storage cavity 3 for storing atomization matrix is formed by surrounding the side of the shell 11 away from the open end 111, the separation support 2 is provided with a first through hole 21 and a second through hole 22 which are spaced apart and communicate with the storage cavity 3; an atomization core 41 is arranged on the side of the separation support 2 away from the storage cavity 3; the atomization matrix flows out from the first through hole 21 and flows to the atomization core 41 through a first path; a blocking piece 5 is blocked on the side of the second through hole 22 away from the storage cavity 3, the blocking piece 5 selectively opens or blocks the second through hole 22 based on the pressure change in the storage cavity 3; the atomization matrix also flows out from the second through hole 22 and flows to the atomization core 41 through a second path.

[0054] In the embodiments of the present application, since the blocking member 5 selectively opens or blocks the second through hole 22 based on the pressure change in the storage cavity 3, when negative pressure occurs in the storage cavity 3, the blocking member 5 can open the second through hole 22, so that the atomized substrate can flow out from the first through hole 21 and flow to the atomizing core 41 through the first path, or flow out from the second through hole 22 and flow to the atomizing core 41 through the second path, that is, the atomized substrate is divided into the second path by the second through hole 22, so that the flow of the atomized substrate flowing out from the first through hole 21 can not be too large, thereby avoiding overflow of the atomized substrate from the first path. The second path can function to divide the atomized substrate and store the atomized substrate, and can conduct the stored atomized substrate to the atomizing core 41, thereby avoiding waste.

[0055] In the embodiments of the present application, when negative pressure occurs in the storage cavity 3, the blocking member 5 can open the second through hole 22, and the atomized substrate can flow out from the second through hole 22 and flow to the atomizing core 41 through the second path, so that the flow of the atomized substrate flowing out from the first through hole 21 can not be too large, and the atomizing core 41 can receive the atomized substrate from the first path or the second path. When the pressure in the storage cavity 3 is balanced, the blocking member 5 can block the second through hole 22, and the atomized substrate flows out from the first through hole 21 and flows to the atomizing core 41 through the first path. The present application can utilize the cooperation of the two different paths based on the pressure change in the storage cavity 3 to guide the atomized substrate to the atomizing core 41, so that the atomizing core 41 can always receive the atomized substrate, and the structure is simple and the cost is low.

[0056] In the embodiments of the present application, the shell 11 is the housing of the atomizer, which is used to mount and arrange the internal devices of the atomizer, such as the atomizing core 41, and protect the internal devices. The shell 11 can also be the appearance part of the atomizer, and the color of the shell 11 can be designed to improve the appearance of the atomizer. As shown in Figure 1 The shell 11 has an accommodating cavity 112 with an open end 111, wherein the isolation support 2 and the atomizing core 41 can be loaded into the accommodating cavity 112 from the open end 111.

[0057] In some embodiments, as shown in Figure 2 and Figure 3 The isolation support 2 can be arranged in the shell 11 and fixedly connected with the inner wall of the shell 11. The isolation support 2 can divide the accommodating cavity 112, and the side of the isolation support 2 away from the open end 111 can be surrounded with the end of the shell 11 away from the open end 111 to form the storage cavity 3, which can be used to place the atomized substrate.

[0058] The isolation support 2 can be fixedly connected with the inner wall of the shell 11 by adhesion, clamping or other methods.

[0059] In some embodiments, the atomizing core 41 is disposed on the side of the isolation bracket 2 opposite to the storage cavity 3, combined with Figure 3 and Figure 4 As shown, a first through hole 21 and a second through hole 22 are provided on the isolation bracket 2. The first through hole 21 is connected to the atomizing core 41, so that the atomizing matrix can flow from the first through hole 21 to the atomizing core 41.

[0060] In some embodiments, the sealing element 5 can selectively open or block the second through hole 22 based on the pressure change within the storage cavity 3. Under normal temperature conditions, the air pressure within the storage cavity 3 is balanced, and the sealing element 5 can block the atomizing core 41. The atomizing matrix flows from the first through hole 21 to the atomizing core 41, and the flow rate is not too large, which can prevent the atomizing matrix from overflowing from the first path. Under high and low temperature conditions, a negative pressure is generated within the storage cavity 3, and the sealing element 5 can open the second through hole 22, allowing the atomizing matrix to flow from the second through hole 22 to the atomizing core 41. The atomizing matrix is ​​diverted to the second path, so that the flow rate of the atomizing matrix flowing out of the first through hole 21 is not too large, thereby preventing the atomizing matrix from overflowing from the first path.

[0061] In this embodiment, the sealing component 5 can automatically adjust whether to open or block the second through hole 22 based on the pressure change in the storage cavity 3, without the need for a switch adjustment. The switching method is simple and timely, which can avoid the oil circuit being blocked and reduce the risk of clogging. Moreover, the atomizing matrix can flow directly to the atomizing core 41 through the second path without the need for a pump, which is conducive to the miniaturization and low cost of the atomizer.

[0062] In some embodiments, such as Figure 5 As shown, the atomizing core 41 may include an atomizing tube 412, a heating element 411 disposed within the atomizing tube 412, and an oil-guiding cotton 413. The oil-guiding cotton 413 is sleeved over the heating element 411. The atomizing tube 412 has a notch for the atomizing substrate to pass through, so that the atomizing substrate is heated by the oil-guiding cotton 413 and transferred to the heating element 411. The heating element 411 may be a heating wire or a heating mesh, etc.

[0063] In some embodiments, the first through hole 21 can always be connected to the atomizing core 41, and the second through hole 22 can be adjusted by the sealing member 5, which can open or close the second through hole 22. The sealing member 5 can completely or partially close the second through hole 22; this embodiment does not specifically limit this.

[0064] In some embodiments, the pressure in the storage cavity 3 is consistent with the atmospheric pressure in the ambient environment at room temperature, i.e., the pressure in the storage cavity 3 is balanced, and the atomized substrate can flow out of the first through hole 21 and flow to the atomized substrate along the first path to continuously provide the atomized substrate. When the storage cavity 3 is at a high or low temperature or in a negative pressure state, the storage cavity 3 has a pressure difference with the outside, and the blocking member 5 can open the second through hole 22, so that the atomized substrate can flow out of the second through hole 22 and flow to the atomized core 41 along the second path. In this way, the flow rate of the atomized substrate at the first through hole 21 will not be too large, and the atomized substrate in the first path can be prevented from overflowing.

[0065] In some embodiments, the size of the first through hole 21 can be smaller than the size of the second through hole 22, so that when the storage cavity 3 and the outside have a pressure difference, the pressure at the second through hole 22 is small, which facilitates the atomized substrate to flow out of the second through hole 22 first, thereby ensuring that the flow rate of the atomized substrate flowing out of the first through hole 21 will not be too large, and effectively preventing the atomized substrate from overflowing from the first path.

[0066] In some embodiments, the number of first through holes 21 can include at least one, for example, one, two, or four, etc. The number of second through holes 22 can include at least one, for example, one or two, etc. By designing the number and size of the first through holes 21 and the number and size of the second through holes 22, the atomized substrate can flow out of the first through hole 21 or the first through hole 21 and the second through hole 22 under different environments.

[0067] In some embodiments, as shown in Figure 6 and Figure 7 the blocking member 5 is a silicone valve with a slit 51. Since the silicone valve is easy to deform with changes in the environment, it is convenient to realize the opening and closing of the second through hole 22 by the blocking member 5 adjusting the environment, and it is convenient to simplify the structure of the blocking member 5, which is conducive to reducing the cost of the atomizer and realizing the miniaturization of the atomizer.

[0068] In some embodiments, as shown in Figure 6 and Figure 7 the silicone valve has a slit 51, so that when there is a pressure difference between the storage cavity 3 and the outside, the silicone valve is easily forced to be broken, so that the atomized substrate can flow along the second path and break the silicone valve. Since the atomized substrate can be an atomized liquid, when the pressure between the storage cavity 3 and the outside is balanced, the silicone valve can block the second through hole 22 under the action of the oil film tension.

[0069] In some embodiments, the number of slits 51 is multiple, the multiple slits 51 are arranged in a circumferential direction along the second through hole 22, and the ends of the multiple slits 51 enclose a central hole 52; the size of the central hole 52, the size of the first through hole 21, and the size of the second through hole 22 increase in turn.

[0070] In the embodiment of the present application, the size of the crack 51 and the center hole 52 is small, which can block the second through hole 22 under the action of the oil film tension, and can be dispersed under the action of the pressure to open the second through hole 22.

[0071] For example, at room temperature, the silicone valve is kept in a closed state under the action of the oil film tension, which can block the second through hole 22; under high and low temperature or negative pressure, the pressure in the storage cavity 3 increases, the oil inlet area of the silicone valve deforms, which causes the center hole 52 to increase, and the second through hole 22 is opened. Since the second through hole 22 is larger than the first through hole 21, the atomization matrix preferentially flows to the atomization core 41 through the second path.

[0072] In some embodiments, the length of the crack 51 in the radial direction of the second through hole 22 ranges from 0.15mm to 0.25mm, and the width of the crack 51 in the circumferential direction of the second through hole 22 ranges from 0.2mm to 0.4mm.

[0073] In the embodiment of the present application, by adjusting the size of the crack 51, it is convenient to ensure that at room temperature, the oil film tension is sufficient to keep the silicone valve in a closed state to block the second through hole 22, and under high and low temperature or negative pressure, the pressure on the silicone valve is sufficient to open the second through hole 22.

[0074] For example, the length of the crack 51 in the radial direction of the second through hole 22 can be 0.15mm, 0.18mm, 0.2mm, 0.22mm, 0.25mm, etc. The width of the crack 51 in the circumferential direction of the second through hole 22 can be 0.2mm, 0.24mm, 0.3mm, 0.32mm, 0.4mm, etc.

[0075] In some embodiments, the number of first through holes 21 is multiple, and the multiple first through holes 21 are arranged at intervals along the circumferential direction of the atomization core 41, and the diameter of the first through hole 21 ranges from 0.6mm to 1.0mm.

[0076] In the embodiment of the present application, the multiple first through holes 21 are arranged at intervals along the circumferential direction of the atomization core 41, which facilitates the atomization matrix to flow to the atomization core 41 from multiple positions in the circumferential direction of the atomization core 41, and improves the atomization effect of the atomization core 41 on the atomization matrix. Moreover, by designing the diameter range of the first through hole 21, it is convenient to ensure that at room temperature, the first through hole 21 can guide sufficient atomization matrix to the atomization matrix through the first path, and the flow capacity of the second through hole 22 can be smaller.

[0077] For example, the diameter of the first through hole 21 can be 0.6mm, 0.68mm, 0.8mm, 0.92mm or 1.0mm, etc.

[0078] In some embodiments, the blocking piece 5 comprises a pressure switch and an air pressure sensor, the air pressure sensor is electrically connected with the pressure switch, the pressure switch is arranged corresponding to the second through hole 22, and the pressure switch is used for opening and closing the second through hole 22.

[0079] In the embodiments of the present application, the pressure difference between the storage cavity 3 and the outside can be detected by the air pressure sensor, and the pressure switch can adjust the opening and closing of the second through hole 22 according to the detection structure, so that the implementation is simple and convenient.

[0080] In some embodiments, in combination with Figure 2 and Figure 3 As shown in the figures, the atomizer comprises a liquid storage piece 42 and a liquid guide piece 43; the liquid storage piece 42 is sleeved outside the atomizing core 41, and the liquid storage piece 42 is blocked on the side of the first through hole 21 away from the storage cavity 3, so that the atomizing substrate flows to the atomizing core 41 through the liquid storage piece 42 after flowing out of the first through hole 21; one end of the liquid guide piece 43 is in contact with the side of the blocking piece 5 away from the second through hole 22, and the other end is in contact with the liquid storage piece 42, so that the atomizing substrate flows to the atomizing core 41 through the liquid guide piece 43 and the liquid storage piece 42 after flowing out of the second through hole 22.

[0081] In the embodiments of the present application, the liquid storage piece 42 can be arranged on the first path for guiding the atomizing substrate to the atomizing core 41, and the liquid guide piece 43 and the liquid storage piece 42 can be combined and arranged on the second path for guiding the atomizing substrate to the atomizing core 41.

[0082] In some embodiments, the liquid storage piece 42 is blocked on the side of the first through hole 21 away from the storage cavity 3, so that the atomizing substrate flowing out of the first through hole 21 can be absorbed by the liquid storage piece 42, the liquid storage piece 42 can store a certain amount of atomizing substrate, and the liquid storage piece 42 can be oil storage cotton, a fiber piece or the like. The liquid storage piece 42 can also play a role in guiding flow, because the liquid storage piece 42 is sleeved outside the atomizing core 41, so that the atomizing substrate on the liquid storage piece 42 can flow to the atomizing core 41, thereby realizing the atomizing core 41 atomizing the atomizing substrate into aerosol.

[0083] In some embodiments, one end of the liquid guide piece 43 is in contact with the side of the blocking piece 5 away from the second through hole 22, and the liquid guide piece 43 can receive the atomizing substrate flowing out of the second through hole 22 when the blocking piece 5 opens the second through hole 22. The liquid guide piece 43 can realize the function of storing a certain amount of atomizing substrate, and also can realize the function of guiding the flow of atomizing substrate, and the liquid guide piece 43 can be oil storage cotton, a high polymer cotton or a fiber piece or the like.

[0084] In some embodiments, the liquid guide 43 comprises a liquid storage portion 431 and a liquid guide portion 432, the liquid storage portion 431 is arranged apart from the liquid storage member 42, one end of the liquid storage portion 431 is in contact with the side of the blocking member 5 away from the second through hole 22, and the other end is in contact with the liquid guide portion 432, and the end of the liquid guide portion 432 away from the liquid storage portion 431 is in contact with the liquid storage member 42.

[0085] In the embodiments of the present application, the liquid guide 43 can be composed of two parts, the liquid storage portion 431 can achieve a better effect of storing the atomized substrate, and the liquid guide portion 432 in contact with the liquid guide 43 can also achieve a better liquid guiding effect.

[0086] In some embodiments, the material of the liquid guide portion 432 and the liquid storage portion 431 is different, the liquid guide portion 432 can use high polymer cotton to ensure that the liquid guide portion has a strong liquid guiding effect, and the liquid storage portion 431 can use oil storage cotton to ensure that the liquid storage portion 431 has a strong oil storage capacity.

[0087] In some embodiments, at high and low temperatures, the blocking member 5 can open the second through hole 22, so that the atomized substrate preferentially flows from the second through hole 22 to the liquid guide portion 432, and it can be avoided that too much atomized substrate flows from the first through hole 21 to the liquid storage member 42 and overflows.

[0088] In some embodiments, the liquid storage portion 431 can comprise oil storage cotton, and the liquid guide portion 432 can comprise oil guide cotton, the fiber direction of the oil storage cotton can be parallel to the axial direction of the second through hole 22, and the fiber direction of the oil guide cotton can be parallel to the radial direction of the second through hole 22.

[0089] In the embodiments of the present application, the atomized substrate flowing out of the second through hole 22 can first flow along the axial direction of the second through hole 22, and then flow along the radial direction of the second through hole 22, which facilitates to lengthen the path length of the second path, so that the liquid guide 43 can store more atomized substrate.

[0111] In the embodiments of the present application, the blocking member selectively opens or blocks the second through hole based on the pressure change in the storage cavity. When negative pressure appears in the storage cavity, the blocking member can open the second through hole, so that the atomized substrate can flow out from the first through hole and flow to the atomization core through the first path, or flow out from the second through hole and flow to the atomization core through the second path, that is, the atomized substrate can be divided into two parts by the second through hole to flow to the second path. Therefore, the flow of the atomized substrate flowing out from the first through hole can be prevented from being too large, and the atomized substrate overflowing from the first path can be avoided. The second path can function as a storage for the atomized substrate, and can conduct the stored atomized substrate to the atomization core, thereby avoiding waste.
