[0071] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0072] Please refer to the following: Figures 1 to 8The first embodiment of this application provides an electronic atomizer 100, including a metering supply chamber 10 and an atomizing host 20. The atomizing host 20 is provided with a liquid storage chamber 21. The metering supply chamber 10 is used to meterly replenish the aerosol generation matrix into the liquid storage chamber 21 in the atomizing host 20, avoiding continuous liquid supply to the liquid storage chamber 21, preventing excessive replenishment of the aerosol generation matrix, and effectively solving the problem of leakage caused by continuous liquid supply from an external liquid storage chamber.

[0073] The quantitative replenishment chamber 10 includes a storage chamber 112 and a constant volume chamber 113. The storage chamber 112 is used to store the aerosol generation matrix; the constant volume chamber 113 is connected to the storage chamber 112 and can receive the aerosol generation matrix in the storage chamber 112. The constant volume chamber 113 is provided with a liquid injection hole 1131 that connects to the liquid storage chamber 21, so that the constant volume chamber 113 can replenish the aerosol generation matrix to the liquid storage chamber 21 of the atomizing host 20 through the liquid injection hole 1131.

[0074] The quantitative replenishment chamber 10 also includes a switch 13, which is at least partially located in the constant volume chamber 113. The switch 13 can move close to the injection port 1131 to block the injection port 1131, or it can move away from the injection port 1131 to allow the injection port 1131 to be open. The aerosol generating matrix in the constant volume chamber 113 can flow to the storage chamber 21 through the injection port 1131. When the storage chamber 112 and the constant volume chamber 113 are in a disconnected state, i.e., the aerosol generating matrix in the storage chamber 112 cannot flow into the constant volume chamber 113, the switch 13 will move away from the injection port 1131, allowing the constant volume chamber 113 to be open to the storage chamber 21. The aerosol generating matrix in the constant volume chamber 113 can then flow into the storage chamber 21 of the atomizing host 20 through the injection port 1131, thus replenishing the storage chamber 21 with the aerosol generating matrix.

[0075] When in use, the user only needs to place the storage chamber 112 and the constant volume chamber 113 in an isolated state, move the switch 13 away from the injection hole 1131, so that the injection hole 1131 is open. The aerosol generating matrix of a certain volume contained in the constant volume chamber 113 will flow into the storage chamber 21 through the injection hole 1131, realizing a quantitative liquid supply to the storage chamber 21, avoiding the addition of excessive aerosol generating matrix to the storage chamber 21, and effectively avoiding leakage problems caused by excessive liquid supply. During the liquid supply process, since the storage chamber 112 and the constant volume chamber 113 are isolated, it is effectively avoided that excessive liquid supply will be caused by continuous liquid supply. After the liquid supply is completed, move the switch 13 close to the injection hole 1131 to block the injection hole 1131, prevent the aerosol generating matrix from continuously flowing into the storage chamber 21, and effectively avoid leakage problems caused by excessive replenishment of aerosol generating matrix during continuous liquid supply.

[0076] The isolation state setting can be configured such that when the electronic atomizer 100 is not in use, the metering chamber 10 is placed horizontally, and the storage chamber 112 and the volumetric chamber 113 are isolated, or the storage chamber 112 and the volumetric chamber 113 are isolated by the movement of the switch 13. Both methods can ensure that the volumetric chamber 113 supplies a metered amount of liquid to the liquid storage chamber 21 of the atomizing host 20, and the volumetric chamber 113 is isolated from the storage chamber 112 during the liquid supply process, thus avoiding leakage problems caused by continuous liquid supply from the external liquid storage chamber.

[0077] The capacity of the liquid storage chamber 21 for storing aerosol generating matrix must match the maximum capacity of the constant volume chamber 113 for holding aerosol generating matrix. When the constant volume chamber 113 is filled with aerosol generating matrix and the liquid storage component 25 is replenished, all aerosol generating matrix in the constant volume chamber 113 can enter the liquid storage chamber 21, preventing overflow.

[0078] Please continue to refer to the following: Figures 1 to 6 , Figure 8 Furthermore, the atomizing host 20 is provided with an alignment hole 22 that communicates with the liquid storage chamber 21. The alignment hole 22 communicates with the liquid injection hole 1131. The metering replenishment chamber 10 is detachably connected to the atomizing host 20, which facilitates the installation and removal of the metering replenishment chamber 10. When the aerosol generating matrix in the metering replenishment chamber 10 is depleted, the user can remove the metering replenishment chamber 10 from the atomizing host 20 for replenishment or replacement. At the same time, the metering replenishment chamber 10 can also be easily separated when the electronic atomizer 100 needs to be cleaned or maintained.

[0079] Specifically, to improve the ease of assembly and disassembly of the metering chamber 10 in the electronic atomizer 100, the metering chamber 10 is equipped with a first retaining structure, and the atomizing host 20 is equipped with a second retaining structure. The first retaining structure and the second retaining structure are connected in a simple, reliable, and easy-to-disassemble manner, ensuring the reliability of the connection between the metering chamber 10 and the atomizing host 20. Please continue reading. Figure 7 Furthermore, the atomizing host 20 also includes an atomizing core 23, which is inserted into and connected to the liquid storage chamber 21. The atomizing core 23 can continuously obtain the aerosol generation matrix. The atomizing core 23 is used to heat and atomize the aerosol generation matrix in the liquid storage chamber 21 for the user to inhale, thus ensuring the normal operation of the electronic atomizer 100.

[0080] Please continue reading. Figure 7 Furthermore, the atomizing host 20 also includes a housing 24 with a liquid storage chamber 21, a liquid storage component 25 installed in the liquid storage chamber 21, a silicone connector installed in the housing 24, a battery 26 for power supply, a control circuit board 27 for controlling the operation of the entire atomizing host 20, a microphone electrically connected to the control circuit board 27, and a mouthpiece 28 installed on the housing 24. The atomizing core 23 is electrically connected to the control circuit board 27, and the control circuit board 27 is electrically connected to the battery 26.

[0081] The control chip on the control circuit board 27 employs an anti-dry-burning control program, which provides an accurate prompt (such as vibration or sound) to replenish the aerosol generating matrix when the aerosol generating matrix in the reservoir 21 is depleted. When the anti-dry-burning program alarms, the aerosol generating matrix in the reservoir 21 has been completely consumed. At this time, the aerosol generating matrix needs to be replenished through the quantitative replenishment chamber 10. This solves the problem of the aerosol generating matrix not being completely consumed when replenishing the aerosol generating matrix, which increases the frequency of replenishment, or the problem of excessive consumption of the aerosol generating matrix in the reservoir 21, causing the atomizing core 23 to produce a burnt taste. This makes it more convenient for users.

[0082] Please refer to the following: Figures 7 to 10 In one embodiment, the quantitative replenishment chamber 10 further includes a chamber body 11 and a partition 12. The chamber body 11 has a receiving cavity 111 for storing the aerosol generation matrix. The partition 12 is placed in the receiving cavity 111, dividing the receiving cavity 111 into a storage cavity 112 and a volume-regulating cavity 113. The partition 12 is provided with a connecting hole 121. When the chamber body 11 is in a first preset state, the liquid level in both the storage cavity 112 and the volume-regulating cavity 113 is lower than the connecting hole 121.

[0083] The first preset state is when the quantitative replenishment chamber 10 replenishes the aerosol generation matrix to the storage chamber 21. Specifically, when the partition 12 extends horizontally, the storage chamber 112 and the constant volume chamber 113 are respectively located above and below the partition 12. If the electronic atomizer 100 is placed vertically during normal use, the chamber 11 extends vertically, and the partition 12 extends horizontally. Under the action of gravity, the aerosol generation matrix in the storage chamber 112 enters the constant volume chamber 113 through the connecting hole 121 of the partition 12. When the electronic atomizer 100 is placed horizontally (i.e., horizontally), the storage chamber 112 and the constant volume chamber 113 are respectively located above and below the partition 12. On both sides of 12, the connecting hole 121 is above the partition 12. The liquid level in the storage chamber 112 and the liquid level in the constant volume chamber 113 are both lower than the connecting hole 121. At this time, the movable switch 13 is away from the injection hole 1131. The constant volume chamber 113 supplies liquid to the storage chamber 21 in a quantitative manner. The partition 12 blocks the aerosol generation matrix in the storage chamber 112 to avoid excessive liquid supply to the constant volume chamber 113 due to continuous liquid supply, which may cause leakage. After the liquid supply is completed, when the electronic atomizer 100 is used, the aerosol generation matrix in the storage chamber 112 enters the constant volume chamber 113 through the connecting hole 121 of the partition 12 under the action of gravity, which replenishes the aerosol generation matrix in the constant volume chamber 113.

[0084] Alternatively, the storage chamber 112 and the constant volume chamber 113 can be distributed below and above the partition 12, respectively. In this case, the electronic atomizer 100 needs to be placed upside down. The aerosol generating matrix in the storage chamber 112 enters the constant volume chamber 113 through the connecting hole 121 of the partition 12 under the action of gravity, thus replenishing the constant volume chamber 113 with the aerosol generating matrix.

[0085] Please continue to refer to the following: Figure 7 and Figure 8 Furthermore, the chamber 11 includes a first side plate 114 and a second side plate 115. The first side plate 114 is provided with an injection hole 1131 for injecting the aerosol generation matrix in the constant volume chamber 113 into the liquid storage chamber 21 of the electronic atomizer 100. The second side plate 115 is spaced apart from the first side plate 114, and the second side plate 115 is provided with a guide hole 116, which is coaxially arranged with the injection hole 1131.

[0086] The switch element 13 passes through the guide hole 116 and can move closer to or further away from the injection hole 1131 along the axial direction of the guide hole 116. The coaxial arrangement of the guide hole 116 and the injection hole 1131 provides guidance for the movement of the switch element 13, preventing the switch element 13 from deviating during movement, ensuring that the switch element 13 can accurately block or open the injection hole 1131, improving the stability and reliability of the operation of the switch element 13, further ensuring the accuracy of quantitative liquid supply, and reducing the risk of leakage.

[0087] Please refer to the following: Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figures 11 to 14 In one embodiment, the quantitative replenishment chamber 10 includes a liquid storage shell 14 with a storage cavity 112, a replenishment shell 15 installed at the lower end of the liquid storage shell 14, and a connecting shell 16 installed on the right side of the replenishment shell 15. During assembly, the replenishment shell 15 is inserted into the connecting shell 16 to form an assembly, and then the assembly is installed at the lower end of the liquid storage shell 14. The liquid storage shell 14 itself is a container. Then, the joints of the components are treated with sealant. The joints of the liquid storage shell 14 inside the connecting shell 16 do not require sealant treatment, and only the external joints require sealant treatment. A volume-fixing cavity 113 is formed between the replenishment shell 15 and the connecting shell 16. The replenishment shell 15 has a first notch 151 at its upper end, and a connecting hole 121 is formed between the first notch 151 and the connecting shell 16. An injection hole 1131 is provided on the left side of the replenishment shell 15, and a guide hole 116 is provided on the right side of the connecting shell 16. Both the replenishment shell 15 and the connecting shell 16 are provided with a light-transmitting structure 117, through which the liquid volume in the volume-fixing cavity 113 can be observed.

[0088] Please refer to the following: Figure 3 , Figure 4 , Figure 9 , Figure 10 , Figures 15 to 17 In one embodiment, the quantitative replenishment chamber 10 includes a liquid storage shell 14 with a storage cavity 112, a replenishment shell 15 installed on the upper end of the liquid storage shell 14, and a connecting shell 16 installed on the right side of the replenishment shell 15. During assembly, the replenishment shell 15 is inserted into the connecting shell 16 to form an assembly, and then the assembly is installed on the upper end of the liquid storage shell 14. The liquid storage shell 14 itself is a container. Then, the joints of each component are treated with sealant. The joints of the liquid storage shell 14 inside the connecting shell 16 do not require sealant treatment, and only the external joints require sealant treatment.

[0089] A volume-fixing cavity 113 is formed between the replenishing shell 15 and the connecting shell 16. A second notch 152 is provided at the lower end of the replenishing shell 15, and a connecting hole 121 is formed between the second notch 152 and the connecting shell 16. An injection hole 1131 is provided on the left side of the replenishing shell 15, and a guide hole 116 is provided on the right side of the connecting shell 16. Both the replenishing shell 15 and the connecting shell 16 are provided with a light-transmitting structure 117, through which the liquid volume in the volume-fixing cavity 113 can be observed.

[0090] Please continue to refer to the following: Figure 9 , Figure 10 , Figure 13 , Figure 14 , Figure 16 and Figure 17 In one embodiment, the switch 13 includes a connecting rod 131, a first sealing part 132, and a second sealing part 133. The connecting rod 131 passes through the guide hole 116 and the injection hole 1131, serving to connect and support the first sealing part 132 and the second sealing part 133. The first sealing part 132 is sleeved on the connecting rod 131 and is press-fitted with the guide hole 116, preventing the aerosol generation matrix from leaking from the guide hole 116 to the outside of the chamber 11. The second sealing part 133 is connected to the end of the connecting rod 131 facing the injection hole 1131 and is press-fitted with the injection hole 1131, ensuring the sealing of the injection hole 1131 after it is blocked by the second sealing part 133.

[0091] The diameter of the second sealing part 133 gradually increases towards the first sealing part 132, so that when the second sealing part 133 approaches and blocks the injection hole 1131, it can fully fit with the injection hole 1131 to form a tight seal and prevent liquid leakage. After the injection hole 1131 is blocked by the second sealing part 133, the aerosol generation matrix in the constant volume chamber 113 is effectively prevented from flowing out, ensuring the accuracy and safety of quantitative liquid supply.

[0092] The switch 13 also includes a handle portion 134 disposed at one end of the first sealing portion 132 away from the second sealing portion 133. The handle portion 134 is located outside the housing 11, making it easy for the user to control the handle portion 134 to drive the entire switch 13 to move. It is easy to operate and more convenient to use.

[0093] Please continue to refer to the following: Figure 9 and Figure 10 Furthermore, the first sealing part 132 is provided with a first thread 1321, and the inner wall of the guide hole 116 is provided with a second thread 1161. The first thread 1321 and the second thread 1161 are fitted together, allowing the switch element 13 to be rotated and moved axially along the guide hole 116. Through the threaded engagement structure of the first thread 1321 and the second thread 1161, the movement of the switch element 13 is more precise and controllable. The operator can rotate the switch element 13 to precisely control the distance of the switch element 13 from or away from the injection hole 1131 as needed, thereby achieving precise adjustment of the opening degree of the injection hole 1131.

[0094] The second sealing part 133 is provided with a third thread 1331, and the inner wall of the injection hole 1131 is provided with a fourth thread 1132. The third thread 1331 and the fourth thread 1132 are configured to cooperate so that after the switch 13 is turned, the second sealing part 133 cooperates to seal the injection hole 1131, which has strong sealing performance and prevents leakage of the quantitative supply chamber when the aerosol generation matrix is ​​not replenished.

[0095] Please refer to the following: Figure 18 and Figure 19 In another embodiment, the switch 13 may also adopt a different structure. The switch 13 includes an actuating element 135 and a blocking element 136. The actuating element 135 is movably disposed on the chamber body 11, and the blocking element 136 is connected to the actuating element 135. The blocking element 136 can block one of the injection hole 1131 and the connecting hole 121 under the action of the actuating element 135.

[0096] When the sealing element 136 blocks the injection hole 1131, the connecting hole 121 opens, allowing the aerosol generating matrix in the storage cavity 112 to flow into the constant volume cavity 113, thus enabling the storage cavity 112 to replenish the constant volume cavity 113 with the aerosol generating matrix. The aerosol generating matrix in the constant volume cavity 113 cannot flow into the liquid storage cavity 21, preventing leakage. When the sealing element 136 blocks the connecting hole 121, the injection hole 1131 opens, preventing the aerosol generating matrix in the storage cavity 112 from flowing into the constant volume cavity 113, allowing the matrix in the constant volume cavity 113 to flow into the liquid storage cavity 21, thus enabling a quantitative supply of liquid to the liquid storage cavity 21 and preventing leakage caused by excessive liquid supply.

[0097] Please continue reading. Figure 1 and Figure 5In one embodiment, the housing 11 has at least a partially light-transmitting structure 117, allowing the user to easily observe the storage status of the aerosol-generating matrix within the housing 11, including the liquid level in the storage chamber 112 and the constant-volume chamber 113. The user can intuitively understand the amount of remaining aerosol-generating matrix in the storage chamber 112, whether the constant-volume chamber 113 has received sufficient matrix for quantitative replenishment, and whether the constant-volume chamber 113 has completed replenishing the storage chamber 21 with aerosol-generating matrix. This helps the user better control the liquid supply process, avoid leakage problems caused by over- or under-supply, and improve the safety and convenience of using the electronic atomizer 100.

[0098] The outer surface of the light-transmitting structure 117 can be set with scales and / or values ​​to indicate the liquid volume, thereby visually indicating the amount of aerosol generating matrix in the cavity. If the predetermined liquid volume is not reached, the storage cavity 112 of the quantitative replenishment chamber 10 is controlled to continue supplying aerosol generating matrix to the fixed volume cavity 113 until the aerosol generating matrix in the fixed volume cavity 113 reaches the predetermined liquid volume; or, when the aerosol generating matrix in the fixed volume cavity 113 exceeds the predetermined liquid volume, the aerosol generating matrix in the fixed volume cavity 113 is controlled to flow back to the storage cavity 112 until the aerosol generating matrix in the fixed volume cavity 113 reaches the predetermined liquid volume, thereby controlling the amount of aerosol generating matrix in the fixed volume cavity 113 to reach the predetermined liquid volume, so as to further ensure the accurate addition / replenishment of liquid to the liquid storage cavity 21 in the later stage, eliminating the problem of inaccurate quality of aerosol generating matrix replenished when the quantitative replenishment chamber 10 supplies liquid.

[0099] Please refer to the following: Figures 20 to 22 In one embodiment, the quantitative replenishment chamber 10 includes a liquid storage shell 14 having a partial storage cavity 112, a connecting shell 16 installed at the lower end of the liquid storage shell 14, a transition liquid shell 17 embedded in the middle of the connecting shell 16, and a replenishment shell 15 embedded in the left side of the connecting shell 16 and abutting against the right side of the transition liquid shell 17.

[0100] During assembly, the replenishing liquid shell 15 and the transition liquid shell 17 are joined together to form the first component. The first component is then inserted into the connecting shell 16 to form the second component. The second component is then inserted into the upper part of the storage shell 14, which serves as a container. The joints between the components are then sealed with sealant. A partial storage cavity 112 is formed between the transition liquid shell 17 and the connecting shell 16, and a constant-volume cavity 113 is formed between the replenishing liquid shell 15 and the connecting shell 16. A connecting hole 121 is provided on the left side of the transition liquid shell 17, and an injection hole 1131 is provided in the middle of the left side of the replenishing liquid shell 15. A guide hole 116 is provided in the middle or upper middle of the right side of the connecting shell 16. A channel 18 is formed between the upper end of the transition liquid shell 17 and the upper end of the connecting shell 16. The connecting shell 16 is provided with a light-transmitting structure 117, which surrounds the third notch 153 of the replenishing liquid shell 15, allowing observation of the liquid volume in the constant-volume cavity 113.

[0101] This application provides a quantitative replenishment chamber and an electronic atomizer. The quantitative replenishment chamber is used to quantitatively replenish the aerosol generation matrix to the liquid storage chamber inside the atomizer, avoiding continuous liquid supply to the liquid storage chamber, preventing excessive replenishment of the aerosol generation matrix, and effectively solving the problem of leakage caused by continuous liquid supply from the external liquid storage chamber.
