[0043] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0044] like Figures 1 to 13As shown, the atomization device includes: a liquid storage body 10, including a shell 11 and a base assembly 12, the shell 11 and the base assembly 12 enclose a liquid storage chamber 101 for storing the atomized matrix; an atomization assembly 20, arranged in the liquid storage chamber 101, for atomizing the atomized matrix to form an aerosol; and a pressure relief portion 001 is provided on the base assembly 12, one end of the pressure relief portion 001 extends to the inner wall surface of the shell 11, and cooperates with the inner wall surface of the shell 11 to form a pressure relief channel 002, the pressure relief channel 002 connects the liquid storage chamber 101 with the outside atmosphere to adjust the pressure inside the liquid storage chamber 101.

[0045] In the embodiment of the present application, since the body and the base assembly 12 are enclosed to form a liquid storage chamber 101 for storing the aerosol matrix, the aerosol matrix can be stored in the liquid storage chamber 101, so that the aerosol assembly 20 in the liquid storage chamber 101 can atomize the aerosol matrix to form an aerosol. Since one end of the pressure relief portion 001 on the base assembly 12 extends to the inner wall surface of the shell 11 and cooperates with the inner wall surface of the shell 11 to form a pressure relief channel 002, if the liquid storage chamber 101 contains an atomizing matrix, even if the atomizing matrix in the liquid storage chamber 101 is used more over time, resulting in an increase in the cavity in the liquid storage chamber 101, when the atomizing device is in a high temperature environment, the volume of the gas in the cavity increases, that is, the gas expands, resulting in an increase in the internal pressure in the liquid storage chamber 101, but the gas in the liquid storage chamber 101 can pass through the pressure relief channel 002 to the outside of the liquid storage chamber 101, thereby reducing the internal pressure of the liquid storage chamber 101, avoiding the problem of the atomizing matrix being squeezed by the high pressure in the liquid storage chamber 101 and leaking. That is, in the embodiment of the present application, by extending one end of the pressure relief portion 001 to the inner wall surface of the shell 11 and cooperating with the inner wall surface of the shell 11 to form a pressure relief channel 002, and the pressure relief channel 002 connects the liquid storage chamber 101 with the outside atmosphere, the problem of leakage of the atomized matrix due to the high pressure in the liquid storage chamber 101 can be effectively avoided, that is, the atomization device can be effectively prevented from leaking the atomized matrix.

[0046] In one embodiment, the pressure relief portion 001 and the inner wall surface of the top of the housing 11 cooperate to form the pressure relief channel, which provides a pressure relief path from top to bottom. Figure 3 , Figure 3 The dotted line portion shows the pressure relief path, and its overall flow direction is from top to bottom.

[0047] Additionally, in some embodiments, Figure 2As shown, the base assembly 12 may include a bracket 121, the bracket 121 includes a bracket body 1211 and a connecting pipe 1212, the bracket body 1211 is connected to one side of the opening of the shell 11, one end of the connecting pipe 1212 is connected to the bracket body 1211 and is connected to the outside atmosphere, one end of the connecting pipe 1212 extends from the bracket body 1211 toward the inner wall surface of the shell 11, the connecting pipe 1212 forms a pressure relief portion 001, and the pressure relief channel 002 is formed between the connecting pipe 1212 and the inner wall surface of the shell 11.

[0048] Since the bracket body 1211 is connected to one side of the opening of the shell 11, the bracket body 1211 can play the role of blocking the opening of the shell 11, and the bracket body 1211 can also provide support for the connecting tube 1212, so that the connecting tube 1212 can be effectively fixed in the liquid storage chamber 101, preventing the connecting tube 1212 from shaking. The connecting tube 1212 is connected to the outside atmosphere, and one end of the connecting tube 1212 extends from the bracket body 1211 toward the inner wall surface of the shell 11, so that the connecting tube 1212 forms a pressure relief portion 001. At this time, once the air pressure in the liquid storage chamber 101 is high, the gas in the liquid storage chamber 101 can flow through the pressure relief channel 002 to the pressure relief portion 001, that is, to the connecting tube 1212, and then flow from the connecting tube 1212 to the outside of the liquid storage chamber 101, effectively reducing the pressure inside the liquid storage chamber 101, thereby effectively preventing the atomization device from leaking the atomized matrix. That is, by providing the support body 1211 and the connecting tube 1212 , a pressure relief portion 001 can be formed in the liquid storage chamber 101 to prevent the atomization device from leaking the atomized matrix.

[0049] For example, Figure 3 As shown, Figure 3 The direction of the arrow A indicates the flow direction of the gas.

[0050] Of course, in the embodiment of the present application, the pressure relief portion 001 may also be of other types, for example, the pressure relief portion 001 may be formed by a pressure relief valve, which is not limited in the embodiment of the present application.

[0051] Additionally, in some embodiments, Figure 2 As shown, a first air channel 1213 is provided in the connecting tube 1212, and a fixing portion 111 is protruded from the inner wall of the shell 11. The end of the connecting tube 1212 away from the bracket body 1211 is sleeved on the fixing portion 111, and a second air channel is formed between the fixing portion 111 and the connecting tube 1212. The second air channel connects the liquid storage chamber 101 and the first air channel 1213, and the first air channel 1213 and the second air channel are connected to form a pressure relief channel 002.

[0052] Because the inner wall of the housing 11 is provided with a protruding fixing portion 111, the end of the connecting tube 1212 away from the bracket body 1211 is sleeved on the fixing portion 111. Therefore, the fixing portion 111 can play a role in fixing the connecting tube 1212, which is equivalent to both ends of the connecting tube 1212 being fixed, that is, one end of the connecting tube 1212 is fixed to the bracket body 1211, and the other end of the connecting tube 1212 is sleeved on the fixing portion 111, which can effectively prevent the problem of the connecting tube 1212 being prone to shaking. A second air channel is formed between the fixing portion 111 and the connecting tube 1212. The second air channel connects the liquid storage chamber 101 and the first air channel 1213. This ensures that when the air pressure in the liquid storage chamber 101 is high, the gas in the liquid storage chamber 101 can flow from the liquid storage chamber 101 to the second air channel, then into the first air channel 1213, and finally flow to the outside of the liquid storage chamber 101, effectively preventing the problem of the atomized matrix being prone to leakage due to the high pressure in the liquid storage chamber 101.

[0053] Additionally, in some embodiments, Figure 2 As shown, a first air channel 1213 is provided in the connecting tube 1212, and a fixed portion 111 is protruded from the inner wall of the shell 11; the atomizing device also includes a pressure relief connector 30, and a plug hole 301 is provided on the pressure relief connector 30. The pressure relief connector 30 is plugged into one end of the connecting tube 1212, and the plug hole 301 is connected to the first air channel 1213. The fixed portion 111 is plugged into the plug hole 301, and a conducting groove 302 is provided on the hole wall of the plug hole 301. The conducting groove 302 and the fixed portion 111 are enclosed to form a third air channel. The first air channel 1213 and the third air channel are connected to form a pressure relief channel 002.

[0054] Since the inner wall of the housing 11 is convexly provided with a fixing portion 111 and the pressure relief connector 30 is provided with a plug-in hole 301, the fixing portion 111 can be plugged into the plug-in hole 301, thereby fixing the pressure relief connector 30 through the fixing portion 111, thereby preventing the pressure relief connector 30 from shaking easily in the oil storage chamber and liquid storage chamber 101. Since the pressure relief connector 30 is plugged into one end of the connecting pipe 1212, after the pressure relief connector 30 is plugged into the fixing portion 111, the connecting pipe 1212 can be fixed by the pressure relief connector 30, thereby preventing the connecting pipe 1212 from shaking easily. In addition, the plug-in hole 301 is connected to the first air channel 1213, and a conducting groove 302 is provided on the hole wall of the plug-in hole 301. The conducting groove 302 can be enclosed with the fixing portion 111 to form a third air channel, which can be The gas expanding in the oil storage chamber 101 first enters the conducting groove 302, that is, enters the third air channel. The gas then flows through the conducting groove 302 and into the first air channel 1213. Finally, the gas flows through the first air channel 1213 and is discharged to the outside of the liquid storage chamber 101. This is equivalent to connecting the first air channel 1213 and the third air channel to form a pressure relief channel 002, thereby preventing the expansion of the gas in the oil storage chamber 101 from causing the atomizer to leak e-liquid. That is, by providing the pressure relief connector 30 and providing the conducting groove 302 on the wall of the plug hole 301 of the pressure relief connector 30, the pressure relief channel 002 can be formed to discharge the expanding gas in the liquid storage chamber 101 to the outside of the liquid storage chamber 101.

[0055] It should be noted that the number of the conducting slots 302 can be set according to actual needs. For example, the number of the conducting slots 302 is 2. For another example, the number of the conducting slots 302 is . The specific number of the conducting slots 302 is not limited in this embodiment of the application.

[0056] Additionally, in some embodiments, Figure 10 As shown, the pressure relief connection piece 30 may include a first connection part 31 and a second connection part 32; the first connection part 31 is connected to the second connection part 32, the outer diameter of the first connection part 31 is larger than the outer diameter of the first connection part 31, a first sub-hole 311 is provided on the first connection part 31, and a second sub-hole 321 is provided on the second connection part 32, the first sub-hole 311 is communicated with the second sub-hole 321, and the first sub-hole 311 and the second sub-hole 321 form a plug-in hole 301, the fixing part 111 is plugged into the first sub-hole 311, and a conducting groove 302 is provided on the hole wall of the first sub-hole 311, and the conducting groove 302 is communicated with the second sub-hole 321.

[0057] Since the first connecting portion 31 is connected to the second connecting portion 32, and the outer diameter of the first connecting portion 31 is larger than the outer diameter of the first connecting portion 31, the second connecting portion 32 can be inserted into the first air passage 1213 of the connecting pipe 1212, thereby facilitating insertion, and the connecting pipe 1212 can be made smaller in size after being connected to the pressure relief connector 30, so that the space occupied by the pressure relief connector 30 in the liquid storage chamber 101 is smaller, thereby allowing the liquid storage chamber 101 to accommodate more atomized matrix. Since a first sub-hole 311 is provided on the first connecting portion 31, and a second sub-hole 321 is provided on the second connecting portion 32, the first sub-hole 311 is connected to the second sub-hole 321, and therefore, the first sub-hole 311 and the second sub-hole 321 form a plug-in hole 301, and the fixing portion 111 can be inserted into the first sub-hole 311, thereby fixing the pressure relief connector 30 inside the liquid storage tank body 10 through the fixing portion 111, thereby avoiding the problem of the pressure relief connector 30 being easy to shake. Since a conducting groove 302 is provided on the hole wall of the first sub-hole 311, and the conducting groove 302 is connected with the second sub-hole 321, once the gas in the liquid storage chamber 101 expands, the expanded gas can flow into the conducting groove 302 and then flow into the second sub-hole 321, and the second sub-hole 321 is connected with the first air channel 1213, so that the gas flowing into the second sub-hole 321 will flow into the first air channel 1213 after flowing through the second sub-hole 321, and finally flow to the outside of the liquid storage chamber 101, so that the expanded gas is discharged to the outside of the liquid storage chamber 101, thereby preventing the excessive pressure in the liquid storage chamber 101 from squeezing the atomized matrix, which then causes the atomized matrix to leak. That is, by providing the first connecting portion 31 and the second connecting portion 32, the gas in the liquid storage chamber 101 can be discharged to the outside of the liquid storage chamber 101, and the connecting tube 1212 can occupy a smaller space in the oil storage tank after being connected to the pressure relief connector 30, which is beneficial to increasing the capacity of the liquid storage chamber 101 to accommodate the atomized matrix.

[0058] It should be noted that both the first connecting portion 31 and the second connecting portion 32 may be cylindrical. Of course, the first connecting portion 31 and the second connecting portion 32 may also be in other shapes, for example, the first connecting portion 31 and the second connecting portion 32 may be prismatic. This embodiment of the present application does not limit this.

[0059] Additionally, in some embodiments, Figure 12 As shown, a first air channel 1213 is provided in the connecting tube 1212, and a sink 112 is formed on the inner wall of the shell 11. The end of the connecting tube 1212 away from the bracket body 1211 is embedded in the sink 112. A fourth air channel 004 is formed between the connecting tube 1212 and the groove wall of the sink 112. The fourth air channel 004 connects the liquid storage chamber 101 and the first air channel 1213. The first air channel 1213 and the fourth air channel 004 are connected to form a pressure relief channel 002.

[0060] Since a groove 112 is formed on the inner wall of the shell 11, the end of the connecting tube 1212 away from the bracket body 1211 is embedded in the groove 112. Therefore, a fourth air channel 004 can be formed between the outer wall of the connecting tube 1212 and the groove wall of the groove 112, and the fourth air channel 004 is respectively connected to the liquid storage chamber 101 and the first air channel 1213. Once the air pressure in the liquid storage chamber 101 is relatively high, the expanded gas can enter the first air channel 1213 through the fourth air channel 004 and be discharged to the outside of the liquid storage chamber 101, avoiding the problem of high pressure in the liquid storage chamber 101, which leads to easy leakage of the atomized matrix. That is, the fourth air channel 004 and the first air channel 1213 form a pressure relief channel 002, ensuring that the gas in the liquid storage chamber 101 can be effectively discharged. In addition, the end of the connecting tube 1212 away from the bracket body 1211 is embedded in the sink 112, which can also ensure that the space occupied by the connecting tube 1212 in the liquid storage chamber 101 is smaller, that is, the sink 112 on the shell 11 accommodates a part of the connecting tube 1212, which can increase the space in the liquid storage chamber 101 that can accommodate the atomized matrix, which is conducive to accommodating more atomized matrix in the liquid storage chamber 101.

[0061] Additionally, in some embodiments, Figure 2 and Figure 13 As shown, the base assembly 12 can also include a bottom cover 122, which covers the opening of the shell 11 and blocks the opening of the shell 11. The bracket 121 is arranged inside the shell 11, and the bracket 121 and the bottom cover 122 are spaced apart. The bottom cover 122 is provided with an air inlet 1221 connected to the outside atmosphere; the bracket 121 is provided with a ventilation groove 1222 on the side facing the bottom cover 122, one end of the ventilation groove 1222 is connected to the air inlet 1221, and the other end of the ventilation groove 1222 is connected to the connecting pipe 1212; the base assembly 12 also includes a liquid absorption assembly 40, which is arranged between the bracket 121 and the bottom cover 122, and the projection of the connecting pipe 1212 along its axial direction is located on the liquid absorption assembly 40.

[0062] Since the bottom cover 122 covers the opening of the shell 11, it is equivalent to blocking the opening of the shell 11 through the bottom cover 122, so that the bottom cover 122 and the inner wall of the shell 11 can enclose the liquid storage chamber 101. Since the bracket 121 is arranged inside the shell 11, and the bracket 121 and the bottom cover 122 are spaced apart, there is a gap between the bracket 121 and the bottom cover 122, and the liquid suction component 40 can be arranged in the gap, so that the projection of the connecting pipe 1212 along its axial direction is located on the suction component, so that the gas flowing out of the first airway 1213 of the connecting pipe 1212 can flow through the liquid suction component 40, and the liquid suction component 40 can effectively absorb the atomized matrix carried in the gas flowing through the liquid suction component 40, so as to avoid the atomized matrix flowing to the outside of the liquid storage chamber 101 with the gas, causing the problem of waste of atomized matrix. In addition, an air inlet 1221 connected to the outside atmosphere is provided on the bottom cover 122; a ventilation groove 1222 is provided on the side of the bracket 121 facing the bottom cover 122, one end of the ventilation groove 1222 is connected to the air inlet 1221, and the other end of the ventilation groove 1222 is connected to the connecting pipe 1212, so that when the air pressure in the liquid storage chamber 101 is too high, once the gas in the liquid storage chamber 101 flows into the first air channel 1213 in the connecting pipe 1212, the gas can flow into the ventilation groove 1222 after flowing out of the first air channel 1213, and flow to the air inlet 1221 through the ventilation groove 1222, so that the gas is discharged from the air inlet 1221, thereby reducing the pressure in the liquid storage chamber 101, avoiding the problem of easy leakage of the atomized matrix due to the high pressure in the liquid storage chamber 101.

[0063] It should be noted that the liquid absorbing assembly 40 may include at least two layers of liquid absorbing members 41, which are stacked and the projection of the connecting tube 1212 along its axial direction is located on one layer of the liquid absorbing member 41. Through such a configuration, once the expanded gas in the liquid storage chamber 101 flows out from the first air channel 1213 of the connecting tube 1212, the gas can flow through the at least two layers of liquid absorbing members 41, so that the at least two layers of liquid absorbing members 41 can effectively absorb the atomized substrate carried in the gas, ensuring that the atomized substrate carried by the gas flowing out of the liquid absorbing assembly 40 is reduced. That is, by configuring the liquid absorbing assembly 40 to include at least two layers of liquid absorbing members 41, it can be effectively ensured that the gas flowing out of the liquid absorbing assembly 40 contains almost no atomized substrate, avoiding the problem of the atomized substrate in the liquid storage chamber 101 being carried out of the atomizing device by the expanded gas.

[0064] It should be noted that the number of layers of the absorbent components 41 in the absorbent assembly 40 can be set according to actual needs. For example, the absorbent assembly 40 includes two layers of absorbent components 41. Another example is that the absorbent assembly 40 includes three layers of absorbent components 41. Another example is that the absorbent assembly 40 includes five layers of absorbent components 41. This embodiment of the present application is not limited to this.

[0065] Additionally, in some embodiments, Figure 13 As shown, the liquid suction component 40 is provided with an air supply channel 401 opposite to and connected to the air inlet hole 1221, and the bracket 121 is also provided with an air hole 1214 opposite to and connected to the air supply channel 401. The end of the ventilation groove 1222 away from the connecting tube 1212 is connected to the air supply channel 401 through the air hole 1214.

[0066] Since the end of the vent groove 1222 away from the connecting tube 1212 is connected to the gas supply channel 401 through the air hole 1214, once the gas in the liquid storage chamber 101 flows out from the first air channel 1213 of the connecting tube 1212, the gas will flow to the vent groove 1222, and the end of the vent groove 1222 away from the connecting tube 1212 is connected to the gas supply channel 401 through the air hole 1214 on the bracket 121, so that the gas will flow through the air hole 1214 and flow into the gas supply channel 401, and the gas supply channel 401 is opposite to and connected with the air inlet hole 1221, so that the gas flowing into the gas supply channel 401 can flow through the gas supply channel 401 and flow to the air inlet hole 1221, and the air inlet hole 1221 is connected to the outside atmosphere, so that the gas in the liquid storage chamber 101 can flow to the outside of the liquid storage chamber 101 through the air inlet hole 1221, thereby avoiding the problem of the atomized matrix being easily leaked due to the high pressure in the liquid storage chamber 101.

[0067] Additionally, in some embodiments, Figure 2 As shown, the atomizing device further includes a first sealing member 50 and a second sealing member 60; the bracket 121 has a first end and a second end opposite to each other along the axial direction of the shell 11, the first sealing member 50 is arranged in the gap between the surface of the bracket 121 facing away from the bottom cover 122 and the first end and the inner wall of the shell 11, and the second sealing member 60 is arranged in the gap between the second end of the bracket 121 and the inner wall of the shell 11.

[0068] Since the first sealing member 50 is disposed in the gap between the surface of the bracket 121 facing away from the bottom cover 122 and the first end and the inner wall of the housing 11, the first sealing member 50 can effectively seal the gap between the first end of the bracket 121 and the inner wall of the housing 11, thereby preventing the atomized matrix in the liquid storage chamber 101 from leaking from the gap. In addition, the second sealing member 60 is disposed in the gap between the second end of the bracket 121 and the inner wall of the housing 11, thereby preventing the atomized matrix in the liquid storage chamber 101 from leaking from the gap. That is, by providing the first sealing member 50 and the second sealing member 60, it is possible to ensure that the liquid storage chamber 101 becomes a relatively closed cavity, thereby preventing the atomized matrix from easily leaking.

[0069] It should be noted that, when the support body 1211 is connected to the connecting pipe 1212 , a through hole may be provided on the first sealing member 50 so that the connecting pipe 1212 can pass through the through hole.

[0070] In addition, in the embodiments of the present application, Figure 2 As shown, the atomizing device may further include a circuit board 70 and an electrode fixing member 80. Both the circuit board 70 and the electrode fixing member 80 are disposed in the gap between the bracket 121 and the bottom cover 122, and the circuit board 70 is plugged into the electrode fixing member 80. Through such an arrangement, the atomizing device can achieve the desired functions through the circuit board 70 and the motor fixing member, and the atomizing device can be specifically controlled through the circuit board 70.

[0071] In addition, in the embodiments of the present application, Figure 5 and Figure 9 As shown, the atomizing device may further include an oil filling plug 100 . The liquid storage tank body 10 is provided with an oil filling hole 90 . The oil filling hole 90 is communicated with the liquid storage cavity 101 . The oil filling plug 100 is inserted into the oil filling hole 110 .
