Abstract
Description
Technical Field
[0001] This application relates to the field of electronic atomization technology, and in particular to a liquid replenishment mechanism and atomization device. Background Technology
[0002] Current electronic atomizers work by heating aerosol products, such as e-liquid, to mix them with air and form an aerosol, which is then inhaled through the mouthpiece. For multi-tank electronic atomizers, e-liquid in the secondary tank can supply e-liquid to the main tank, thus increasing the number of puffs and appealing to a wider audience.
[0003] However, once the existing auxiliary oil tank is connected to the main oil tank, it is difficult to adjust the oil supply to the main oil tank, which can easily cause excessive oil pressure in the main oil tank and lead to oil leakage. Another issue is that the opening and closing structure of the oil supply holes of the auxiliary oil tank and the main oil tank is relatively complicated, making it very inconvenient to use.

[0024] This application describes an atomizing device (also referred to as an "electronic atomizer," "atomizer," or "cartridge") that can atomize a liquid matrix to generate an aerosol.
[0025] A liquid matrix is a material used to generate aerosols, and typically consists of at least one chemical substance capable of producing aerosols. Liquid matrices are activated through atomization methods such as heating atomization or ultrasonic atomization to form aerosols.
[0026] In some embodiments, the liquid matrix may be a liquid containing plant-based substances, including volatile plant-based fragrance components, or a liquid containing non-plant-based substances. For example, the liquid matrix may include water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures.
[0027] In some embodiments, the liquid matrix may also be referred to as "e-liquid".
[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an atomizing device in some embodiments of this application. The atomizing device 100 may include a power supply mechanism 10, an atomizing mechanism 20 connected to the power supply mechanism 10, and a liquid replenishment mechanism 30 for storing a liquid matrix and connected to the atomizing mechanism 20. The power supply mechanism 10 supplies power to the atomizing mechanism 20. The liquid replenishment mechanism 30 introduces the liquid matrix into the atomizing mechanism 20. The atomizing mechanism 20 atomizes the introduced liquid matrix. In some embodiments, the atomizing mechanism 20 can activate the liquid matrix through atomization methods such as heating atomization or ultrasonic atomization to form an aerosol.
[0029] It is understandable that the connection between the atomizing mechanism 20 and the liquid replenishing mechanism 30 can refer to the internal connection between the atomizing mechanism 20 and the liquid replenishing mechanism 30 to realize the transfer of liquid matrix, or it can refer to a direct structural connection or an indirect connection through other structures.
[0030] The atomizing mechanism 20 is connected to the liquid replenishment mechanism 30, allowing the liquid matrix within the liquid replenishment mechanism 30 to be introduced into the atomizing mechanism 20. The atomizing mechanism 20 can further atomize the liquid matrix introduced from the liquid replenishment mechanism 30 to generate an aerosol.
[0031] In some embodiments, the power supply mechanism 10 may include at least a battery to provide power to the atomizing mechanism 20.
[0032] In some embodiments, at least two of the power supply mechanism 10, the atomizing mechanism 20, and the liquid replenishment mechanism 30 may be connected together by means of plug-in connection, threaded connection, snap-fit connection, sleeve connection, clamp connection, or other means known to those skilled in the art.
[0033] In some embodiments, any two of the three connected components—power supply mechanism 10, atomizing mechanism 20, and liquid replenishment mechanism 30—can be detachably connected to allow for replacement of the power supply mechanism 10, liquid replenishment mechanism 30, or atomizing mechanism 20.
[0034] It is understood that the connection and positional relationships among the power supply mechanism 10, the atomizing mechanism 20 and the liquid replenishment mechanism 30 can be set according to the needs of those skilled in the art, and are not limited to the embodiments listed herein.
[0035] In some embodiments, the power supply mechanism 10 may be connected to the atomizing mechanism 20 and the liquid replenishment mechanism 30. In some embodiments, the atomizing mechanism 20 may be connected to the power supply mechanism 10 and the liquid replenishment mechanism 30. In some embodiments, the liquid replenishment mechanism 30 may be connected to the power supply mechanism 10 and the atomizing mechanism 20.
[0036] In some embodiments, the atomizing device 100 may further include a housing to accommodate the power supply mechanism 10, the atomizing mechanism 20, and the refill mechanism 30. In some embodiments, the housing may serve as the housing of the power supply mechanism 10, and further, in some embodiments, the housing of the power supply mechanism 10 may accommodate the atomizing mechanism 20 and the refill mechanism 30, and connect the atomizing mechanism 20 and the refill mechanism 30 to improve the appearance of the atomizing device 100.
[0037] Please see Figure 2 , Figure 3 and Figure 4 , Figure 2 for Figure 1 The illustrated embodiment is a schematic diagram of at least a portion of the structure of the atomizing device 100 in some embodiments. Figure 3 for Figure 2 The atomizing device 100 in the illustrated embodiment is an exploded view in some embodiments. Figure 4 for Figure 2The diagram shows an exploded view of the atomizing mechanism 20 in some embodiments. The overall shape of the atomizing mechanism 20 can enclose an installation space 2101 to cooperate with the liquid replenishment mechanism 30. In some embodiments, the atomizing mechanism 20 can be L-shaped, thus having a missing area compared to a rectangular structure, and this missing area can be the installation space 2101.
[0038] In some embodiments, the atomizing mechanism 20 and the replenishing mechanism 30 may be located on the same side of the power supply mechanism 10. The atomizing mechanism 20 may connect the power supply mechanism 10 and the replenishing mechanism 30. In a further embodiment, a portion of the atomizing mechanism 20 may be connected to the replenishing mechanism 30 on one side, and another portion may be disposed on the other side of the replenishing mechanism 30. These two portions of the atomizing mechanism 20 may enclose and form an installation space 2101 for accommodating the replenishing mechanism 30. In a further embodiment, this portion of the atomizing mechanism 20 may be arranged side by side with the replenishing mechanism 30 and connected to the power supply mechanism 10, while the other portion may be placed between the power supply mechanism 10 and the replenishing mechanism 30 and connected to the power supply mechanism 10. Moreover, the replenishing mechanism 30 may abut and cooperate with this other portion.
[0039] In some embodiments, the atomizing mechanism 20 may include a mounting base 21 and an atomizing core assembly 22 mounted on the mounting base 21. The atomizing core assembly 22 may be partially placed within the mounting base 21, thereby atomizing the liquid matrix within the mounting base 21. For example, the liquid matrix may be activated by atomization methods such as heating atomization or ultrasonic atomization to form an aerosol.
[0040] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 5 for Figure 4 The illustrated embodiment shows a cross-sectional view of the mounting base 21 along line VV. Figure 6 for Figure 4 The illustrated embodiment shows a cross-sectional view of the mounting base 21 along line VI-VI. The mounting base 21 may have a mounting space 2102 to accommodate a liquid matrix. In some embodiments, the mounting base 21, such as the mounting space 2102, may communicate with the liquid replenishment mechanism 30. In some embodiments, the mounting base 21, such as the mounting space 2102, may accommodate an atomizing mechanism 20 so that the liquid matrix within the mounting base 21, such as the mounting space 2102, comes into contact with the atomizing mechanism 20 and is atomized by the atomizing mechanism 20.
[0041] In some embodiments, the mounting base 21 may have an air intake channel 2103 communicating with the mounting space 2102, so that outside air can enter the mounting space 2102 and mix with the gas after the liquid matrix is atomized to form an aerosol. In some embodiments, the air intake channel 2103 may extend towards the side close to the power supply mechanism 10 and may communicate with the inside of the power supply mechanism 10, so that air flows through the power supply mechanism 10 into the air intake channel 2103, and further into the mounting base 21, such as the mounting space 2102.
[0042] In some embodiments, the mounting base 21 may have a liquid inlet channel 2104 communicating with the mounting space 2102, so that the interior of the liquid replenishing mechanism 30 communicates with the mounting base 21, for example, the assembly space 2102, through the liquid inlet channel 2104. In some embodiments, the liquid inlet channel 2104 may extend into the mounting space 2101, and thus communicate with the liquid inlet channel 2104 when the liquid replenishing mechanism 30 is installed in the mounting space 2101.
[0043] In some embodiments, the mounting base 21 may have a mounting hole 2105 communicating with the mounting space 2102 to install the atomizing core assembly 22, allowing the atomizing core assembly 22 to extend into the mounting base 21, for example, the mounting space 2102. In some embodiments, the mounting hole 2105 may be designed accordingly based on different installation methods of the mounting base 21 and the atomizing core assembly 22. Furthermore, when the mounting base 21 and the atomizing core assembly 22 are inserted and mated, the mounting hole 2105 may also be referred to as a "mating hole," facilitating the insertion and mating of the mounting base 21 and the atomizing core assembly 22 at the mating hole.
[0044] In some embodiments, the mounting base 21 may be provided with a first connector 211 at the mounting space 2101 to connect with the liquid replenishing mechanism 30, so that the liquid replenishing mechanism 30 is installed within the mounting space 2101. In some embodiments, the first connector 211 may be detachably connected to the liquid replenishing mechanism 30. In some embodiments, the first connector 211 may be plugged into or snapped into the liquid replenishing mechanism 30. In some embodiments, while the first connector 211 is connected to the liquid replenishing mechanism 30, the liquid replenishing mechanism 30 may also communicate with the mounting base 21, for example, within the mounting space 2102. In some embodiments, the liquid replenishing mechanism 30 may slide along the surface of another part of the mounting base 21 toward the side closer to this part of the mounting base 21, thereby connecting the liquid replenishing mechanism 30 with the first connector 211 and communicating with the mounting base 21, for example, within the mounting space 2102.
[0045] In some embodiments, the mounting base 21 may have an electrical connection end 212 provided on the inner wall surface of the mounting space 2102 for electrical connection with the atomizing core assembly 22 to supply power to the atomizing core assembly 22. In some embodiments, the electrical connection end 212 may be connected to the power supply mechanism 10, thereby enabling the power supply mechanism 10 to supply power to the atomizing core assembly 22 through the electrical connection end 212. In some embodiments, when the atomizing core assembly 22 extends into the mounting base 21, for example, the mounting space 2102, it may abut against the electrical connection end 212 to achieve electrical connection.
[0046] In some embodiments, the mounting base 21 may be provided with a liquid-absorbing element 213 within the air intake channel 2103. When the condensed liquid matrix flows out of the air intake channel 2103, it can be adsorbed by the liquid-absorbing element 213, effectively preventing the condensed liquid matrix from flowing out of the air intake channel 2103. In some embodiments, in order to effectively prevent the condensed liquid matrix from flowing out of the air intake channel 2103, the air intake channel 2103 may be configured to be curved, thereby increasing the difficulty for the condensed liquid matrix to flow out of the air intake channel 2103, and further increasing the chance of the condensed liquid matrix coming into contact with the liquid-absorbing element 213.
[0047] Please see Figure 4 and Figure 7 , Figure 7 for Figure 4 The illustrated embodiment shows a cross-sectional view of the atomizer core assembly 22 along line VII-VII. The atomizer core assembly 22 is detachably connected to the mounting hole 2105 to facilitate replacement of the atomizer core assembly 22.
[0048] In some embodiments, the atomizing core assembly 22 can block the air intake channel 2103 within the assembly space 2102 and can have an atomizing chamber 2201 communicating with the air intake channel 2103, thereby allowing gas to enter the atomizing chamber 2201 through the air intake channel 2103 and mix with the gas after the liquid matrix is atomized to form an aerosol. In some embodiments, the air intake channel 2103 is blocked while the atomizing core assembly 22 is detachably connected to the assembly hole 2105. In some embodiments, the atomizing core assembly 22 can divide the assembly space 2102 into a space communicating with the liquid inlet channel 2104, allowing the liquid matrix entering through the liquid inlet channel 2104 to contact the atomizing core assembly 22 and further enter the atomizing chamber 2201 to be atomized by the atomizing core assembly 22.
[0049] In some embodiments, the atomizing core assembly 22 may extend from the assembly space 2102 into the air intake channel 2103 or at the end of the air intake channel 2103, blocking the air intake channel 2103, allowing gas to enter the atomization chamber 2201 through the air intake channel 2103 and mix with the gas after the liquid matrix is atomized to form an aerosol. Furthermore, the portion of the assembly space 2102 outside the atomizing core assembly 22 may communicate with the liquid inlet channel 2104, allowing the liquid matrix entering through the liquid inlet channel 2104 to contact the atomizing core assembly 22 and further enter the atomization chamber 2201 to be atomized by the atomizing core assembly 22.
[0050] In some embodiments, the atomizing core assembly 22 can extend into the assembly space 2102, blocking the assembly hole 2105, thereby connecting the atomizing chamber 2201 with the assembly space 2102. This achieves the effect of blocking the air intake channel 2103, allowing gas to enter the assembly space 2102 through the air intake channel 2103 and further into the atomizing chamber 2201, where it mixes with the atomized liquid matrix to form an aerosol. In a further embodiment, the atomizing core assembly 22 can divide the assembly space 2102 into two parts: one part connects the air intake channel 2103 and the assembly space 2102, and the other part connects the liquid inlet channel 2104, allowing the liquid matrix entering through the liquid inlet channel 2104 to contact the atomizing core assembly 22 and further enter the atomizing chamber 2201 to be atomized by the atomizing core assembly 22.
[0051] In some embodiments, the atomizing core assembly 22 can atomize the liquid matrix at a location corresponding to the atomizing chamber 2201.
[0052] In some embodiments, the atomizing core assembly 22 may have a transmission channel 2202 connecting the atomizing chamber 2201 to the outside of the atomizing mechanism 20. The transmission channel 2202 facilitates aerosol discharge. In some embodiments, the transmission channel 2202 may form a mouthpiece 221 at the opening on the outer surface of the atomizing mechanism 20, so that the user can inhale through the mouthpiece 221.
[0053] In some embodiments, the portion of the atomizing core assembly 22 placed in the mounting base 21, such as the mounting space 2102, is configured to allow the liquid matrix to enter the atomizing chamber 2201 and be atomized by the atomizing core assembly 22.
[0054] In some embodiments, the portion of the atomizing core assembly 22 placed within the assembly space 2102 is configured with a return air channel 2203 connecting the transmission channel 2202 and the assembly space 2102. Furthermore, the return air channel 2203 is connected to the liquid inlet channel 2104. This allows external gas to enter the assembly space 2102 through the transmission channel 2202 and the return air channel 2203, and further enter the liquid replenishment mechanism 30 through the return air channel 2203, replenishing the negative pressure within the liquid replenishment mechanism 30 caused by the discharge of the liquid matrix.
[0055] In some embodiments, the atomizing core assembly 22 and the liquid replenishment mechanism 30 may be located on the same side of the mounting base 21. The atomizing core assembly 22 is inserted and engaged with the mounting base 21 at the mounting hole 2105, and is detachably connected to the liquid replenishment mechanism 30.
[0056] Please see Figure 7 The atomizing core assembly 22 may include a mouthpiece 221, a core 222 connected to the mouthpiece 221, and a seal 223 disposed between the mouthpiece 221 and the core 222.
[0057] The core 222 serves as the main body for atomizing the liquid matrix in the atomizing core assembly 22. The atomizing chamber 2201 is disposed within the core 222. The liquid matrix entering the assembly space 2102 can enter the atomizing chamber 2201 through the core 222.
[0058] In some embodiments, the core 222 can be used to block the air intake passage 2103. In some embodiments, the core 222 can be used to abut the electrical connection end 212 to achieve electrical connection.
[0059] In some embodiments, the nozzle 221 may be provided with a second connector 2211 for connection with the refill mechanism 30, further enabling the refill mechanism 30 to be installed within the mounting space 2101. In some embodiments, the atomizing core assembly 22, for example, the second connector 2211, may be detachably connected to the refill mechanism 30. In some embodiments, the atomizing core assembly 22, for example, the second connector 2211, may be connected to the refill mechanism 30 via a plug-in or snap-fit connection. In some embodiments, while the atomizing core assembly 22 is connected to the mounting base 21, the atomizing core assembly 22, for example, the second connector 2211, may also be connected to the refill mechanism 30.
[0060] In some embodiments, the atomizing core assembly 22 can slide into the assembly space 2102 along the assembly hole 2105, so that the atomizing core assembly 22 can be connected to the assembly base 21, and the atomizing core assembly 22, for example, the second connector 2211 can be moved and connected to the liquid replenishment mechanism 30.
[0061] The seal 223 is used to achieve a sealed connection between the nozzle 221 and the core 222. In a further embodiment, the seal 223 can also be used to achieve a sealed connection between the atomizing core assembly 22 and the mounting base 21. In some embodiments, the seal 223 can be sealed to the inner wall surface of the mounting hole 2105.
[0062] The seal 223 may be made of nitrile rubber, EPDM rubber, fluororubber, silicone rubber, fluorosilicone rubber, nylon, polyurethane, engineering plastics, or other sealing devices well known in the art. The seal 223 may be annular, plate-shaped, or other shapes, depending on the sealing location and sealing method.
[0063] The sealing element 223 can support the core 222 and also seal the nozzle 221 and the core 222.
[0064] In some embodiments, the nozzle 221 may be connected to one end of the core 222 and may form a first channel 2204. In some embodiments, the core 222 and the seal 223 form a sealed space 2205 communicating with the first channel 2204. In some embodiments, the seal 223 may form a second channel 2206 communicating with the sealed space 2205 between the nozzle 221 and the core 222.
[0065] In some embodiments, the return gas channel 2203 may include a first channel 2204, a sealing space 2205, and a second channel 2206. In some embodiments, the first channel 2204 may communicate with the transmission channel 2202 and extend away from the atomizing chamber 2201, and communicate with the sealing space 2205, thereby making it difficult for condensed liquid matrix to enter the sealing space 2205 from the first channel 2204, and allowing gas to flow within the first channel 2204 and the sealing space 2205. In some embodiments, the sealing space 2205 extends away from the atomizing chamber 2201 from the point of communication with the first channel 2204, and extends towards the atomizing chamber 2201, and communicates with the second channel 2206. Therefore, when the liquid matrix flows into the sealed space 2205 from the second channel 2206, it will likely flow to the side away from the atomizing chamber 2201, and is unlikely to remain at the connection between the first channel 2204 and the sealed space 2205, and thus it is difficult to flow into the transmission channel 2202 through the first channel 2204.
[0066] In some embodiments, the second channel 2206 can connect the sealing space 2205 and the assembly space 2102, and then connect with the liquid inlet channel 2104, thereby realizing the connection between the return gas channel 2203 and the liquid inlet channel 2104.
[0067] Please see Figure 4The atomizing core assembly 22, such as the core body 222, may be provided with a liquid inlet hole 2207 that communicates with the atomizing chamber 2201. When the liquid matrix enters the assembly space 2102 through the liquid inlet channel 2104, it can enter the atomizing chamber 2201 through the liquid inlet hole 2207, so that the liquid matrix is atomized by the atomizing core assembly 22, such as the core body 222.
[0068] In some embodiments, the atomizing core assembly 22, such as the core body 222, may be provided with a heating element 2221 located within the atomizing chamber 2201, thereby heating the liquid matrix and achieving atomization. To further enhance atomization, the atomizing core assembly 22, such as the core body 222, may also be provided with a liquid guiding element located within the atomizing chamber 2201. The liquid guiding element abuts against the heating element 2221 and fills the portion corresponding to the liquid inlet 2207, allowing the liquid matrix to enter the atomizing chamber 2201 from the liquid inlet 2207, be absorbed by the liquid guiding element, and guided to the heating element 2221.
[0069] Please see Figure 2 , Figure 3 , Figure 8 and Figure 9 , Figure 8 for Figure 3 The schematic diagram of the liquid replenishment mechanism 30 in the illustrated embodiment is shown from another perspective. Figure 9 for Figure 8 The illustrated embodiment shows a cross-sectional view of the replenishing mechanism 30 along line IX-IX. The replenishing mechanism 30 may have a receiving space 3101 for storing the liquid matrix, and also a liquid outlet channel 3102 communicating with the receiving space 3101. The liquid matrix may enter the liquid outlet channel 3102 from the receiving space 3101 for further discharge. In a further embodiment, it may be atomized by an atomizing mechanism 20, such as an atomizing core assembly 22.
[0070] In some embodiments, the liquid outlet channel 3102 may be connected to the atomizing core assembly 22, such as the liquid inlet channel 2104, to further connect with the atomizing core assembly 22, such as the assembly space 2102. In this way, the liquid matrix can enter the receiving space 3101 through the liquid outlet channel 3102 and the liquid inlet channel 2104.
[0071] The refill mechanism 30 may include a refill body 31 having a receiving space 3101 and a liquid outlet channel 3102, a normally closed open valve 33 installed at the liquid outlet channel 3102, and a pressing component 32 disposed on and exposed on the refill body 31. The normally closed open valve 33 can be used to block the liquid outlet channel 3102, thereby preventing the liquid matrix in the refill body 31, such as the receiving space 3101, from being discharged from the liquid outlet channel 3102. The pressing component 32 is designed to be user-operable, allowing the normally closed open valve 33 to be triggered within the receiving space 3101 or the liquid outlet channel 3102 to open the liquid outlet channel 3102, thereby allowing the liquid matrix in the refill body 31, such as the receiving space 3101, to be discharged from the liquid outlet channel 3102, and further discharged into the atomizing core assembly 22, such as the assembly space 2102.
[0072] In some embodiments, while the first connector 211 can be connected to the liquid replenishment mechanism 30, the liquid outlet channel 3102 and the liquid inlet channel 2104 can also be connected.
[0073] In some embodiments, the fluid replenishing body 31 is provided with a mounting hole 3103 communicating with the receiving space 3101, so as to install the pressing component 32 at the mounting hole 3103, so that the pressing component 32 extends into the receiving space 3101, and can further trigger the normally closed conducting valve 33.
[0074] In some embodiments, the replenishing body 31 may also have an injection hole 3104 communicating with the receiving space 3101, so as to replenish the liquid through the injection hole 3104 when the liquid matrix in the replenishing mechanism 30, for example, is low. In some embodiments, in order to effectively prevent the liquid matrix from leaking from the injection hole 3104, the replenishing body 31 may also be provided with a sealing member 311, which is used to seal the injection hole 3104, effectively preventing the liquid matrix from leaking from the injection hole 3104. Of course, the sealing member 311 may also leave the injection hole 3104 open, so as to facilitate the user to inject liquid through the injection hole 3104.
[0075] Please see Figure 2 The fluid replenishing body 31 may be provided with a third connector 312 for detachable connection with the mounting base 21, such as the first connector 211, for example, by means of a plug-in fit or a snap-fit connection. In some embodiments, the first connector 211 is provided with a groove or a through hole, and the third connector 312 is provided with a protrusion, so that when the protrusion extends into the groove or the through hole, the fluid replenishing body 31, such as the third connector 312, is detachably connected to the mounting base 21, such as the first connector 211.
[0076] Please see Figure 3The refill body 31 may be provided with a fourth connector 313 for detachable connection with the atomizing core assembly 22, such as the second connector 2211, for example, by plug-in engagement or snap-fit connection. In some embodiments, the second connector 2211 is provided with a groove or a through hole, and the fourth connector 313 is provided with a protrusion, so that when the protrusion extends into the groove or the through hole, the refill body 31, such as the fourth connector 313, is detachably connected to the atomizing core assembly 22, such as the second connector 2211.
[0077] In some embodiments, the sealing element 311 may be made of nitrile rubber, EPDM rubber, fluororubber, silicone rubber, fluorosilicone rubber, nylon, polyurethane, engineering plastics, or other sealing devices well known in the art. The shape of the sealing element 311 may be configured according to the sealing location and sealing method.
[0078] Please see Figure 9 and Figure 10 , Figure 10 for Figure 9 The illustrated embodiment shows a schematic diagram of the pressing assembly 32 in some embodiments. The pressing assembly 32 may include a pressing rod 321 installed at the mounting hole 3103 and a first reset member 322 disposed between the pressing rod 321 and the refill body 31. The pressing rod 321 can extend into the refill mechanism 30, for example, the receiving space 3101, and can trigger the normally closed conducting valve 33. The first reset member 322 facilitates the reset of the pressing rod 321 and can reset the pressing rod 321 to a position that does not trigger the normally closed conducting valve 33.
[0079] The push rod 321 can be inserted into the fluid replenishment mechanism 30, such as the receiving space 3101, to trigger the normally closed conducting valve 33 when operated by the user. When the user does not operate the push rod 321, the first reset member 322 can reset the push rod 321 to a position where the normally closed conducting valve 33 is not triggered.
[0080] In some embodiments, the pressing rod 321 can be sealed to the wall of the mounting hole 3103 to effectively prevent the liquid matrix from leaking from the mounting hole 3103.
[0081] In some embodiments, the pressing rod 321 can trigger the normally closed open valve 33 within the receiving space 3101 or the liquid outlet channel 3102. In some embodiments, the pressing assembly 32, such as the pressing rod 321, can slide from the mounting hole 3103 into the receiving space 3101 or the liquid outlet channel 3102 to trigger the normally closed open valve 33.
[0082] In some embodiments, to reduce the difficulty of discharging the liquid matrix from the outlet channel 3102 or to accelerate the discharge speed of the liquid matrix from the outlet channel 3102 when the normally closed valve 33 is open, a pusher plate, such as a first pusher plate 3211, is provided on the side periphery of the pressing rod 321. The pusher plate, such as the first pusher plate 3211, can move with the pressing rod 321, and thus, when the pressing rod 321 triggers the normally closed valve 33, the pusher plate, such as the first pusher plate 3211, will also move. In some embodiments, the pusher plate, such as the first pusher plate 3211, can be disposed in the mounting hole 3103. Furthermore, when the pressing rod 321 moves, the pusher plate, such as the first pusher plate 3211, can push the liquid matrix or gas in the mounting hole 3103, increasing the pressure in the liquid replenishment mechanism 30, such as the receiving space 3101, thereby causing the liquid matrix to enter the outlet channel 3102 under pressure and be discharged.
[0083] In some embodiments, the pusher, such as the first pusher 3211, may slide only within the mounting hole 3103. In some embodiments, the pusher, such as the first pusher 3211, may be sealed to the wall of the mounting hole 3103 to better control the pressure within the fluid replenishment mechanism 30, such as the receiving space 3101. In some embodiments, the pusher, such as the first pusher 3211, may slide from the mounting hole 3103 into the receiving space 3101, or vice versa.
[0084] In some embodiments, a liquid pusher, such as a first liquid pusher 3211, may be disposed within the receiving space 3101. Furthermore, when the pressing rod 321 moves, the liquid pusher, such as the first liquid pusher 3211, may push the liquid matrix or gas within the receiving space 3101, increasing the pressure within the liquid replenishment mechanism 30, such as the receiving space 3101, thereby causing the liquid matrix to enter the outlet channel 3102 under pressure and be discharged.
[0085] In some embodiments, to reduce the difficulty of discharging the liquid matrix from the outlet channel 3102 or to accelerate the discharge speed of the liquid matrix from the outlet channel 3102 when the normally closed valve 33 is open, a pusher plate, such as a second pusher plate 3212, is provided on the side periphery of the pressing rod 321. The pusher plate, such as the second pusher plate 3212, can move with the pressing rod 321, and thus, when the pressing rod 321 triggers the normally closed valve 33, the pusher plate, such as the second pusher plate 3212, will also move. In some embodiments, the pusher plate, such as the second pusher plate 3212, can be disposed within the receiving space 3101. Furthermore, when the pressing rod 321 moves, the pusher plate, such as the second pusher plate 3212, can push the liquid matrix or gas in the mounting hole 3103, increasing the pressure in the liquid replenishment mechanism 30, such as the receiving space 3101, thereby causing the liquid matrix to enter the outlet channel 3102 under pressure and be discharged.
[0086] In some embodiments, the pusher, such as the second pusher 3212, may slide only within the receiving space 3101.
[0087] In some embodiments, to better reduce the difficulty of discharging the liquid matrix from the outlet channel 3102, or to accelerate the discharge speed of the liquid matrix from the outlet channel 3102, the projected area of the first pusher plate 3211 along the axial direction of the pressing rod 321 is smaller than the projected area of the second pusher plate 3212; or the projected area of the first pusher plate 3211 is located within the projected area of the second pusher plate 3212. In a further embodiment, when the first pusher plate 3211 pushes air, the second pusher plate 3212 can better push the liquid matrix.
[0088] In some embodiments, to better reduce the difficulty of discharging the liquid matrix from the outlet channel 3102, or to accelerate the discharge speed of the liquid matrix from the outlet channel 3102, the pressing component 32, such as the pressing rod 321, is spaced apart from the normally closed conducting valve 33 when the pressing component 32, such as the pressing rod 321, is in the initial position. Furthermore, when the user presses the pressing component 32, such as the pressing rod 321, and triggers the normally closed conducting valve 33, the pressing component 32, such as the pressing rod 321, extends into the receiving space 3101, compressing the gas in the receiving space 3101 and pre-generating positive pressure. Then, at the instant the pressing component 32, such as the pressing rod 321, triggers the normally closed conducting valve 33, the positive pressure compresses the liquid matrix, allowing it to be smoothly discharged through the outlet channel 3102.
[0089] In some embodiments, the normally closed valve 33 may be a valve well known to those skilled in the art, such as a check valve. The normally closed valve 33 is normally closed and may be opened when the pressing component 32, such as the pressing rod 321, abuts against the valve, or when the pressure exerted by the liquid matrix on the normally closed valve 33 exceeds a predetermined pressure. Furthermore, when the pressing component 32, such as the pressing rod 321, triggers the normally closed valve 33, it may or may not abut against the normally closed valve 33.
[0090] In some embodiments, the first reset member 322 may be an elastic member capable of elastic deformation, thereby being able to elastically deform when the pressing component 32, such as the pressing rod 321, is operated by the user, and can drive the pressing component 32, such as the pressing rod 321, to move based on the elastic deformation when the pressing component 32, such as the pressing rod 321, is not operated by the user. In some embodiments, the first reset member 322 may be a structure supported by a spring or other elastic material.
[0091] Please see Figure 9 and Figure 11 , Figure 11 for Figure 9The illustrated embodiment shows a schematic diagram of the normally closed on-state valve 33 in some embodiments. The normally closed on-state valve 33 may include a mounting base 331, a sealing body 332, and a second reset member 333. The sealing body 332 may be slidably connected to the mounting base 331. The second reset member 333 may be disposed between the mounting base 331 and the sealing body 332.
[0092] In some embodiments, the mounting base 331 and the sealing body 332 may be installed at the liquid outlet channel 3102. The sealing body 332 can be used to block the liquid outlet channel 3102 and can also be used to abut against the pressing assembly 32, such as the pressing rod 321, so that it can be pushed by the pressing assembly 32, such as the pressing rod 321, to a position where the liquid outlet channel 3102 is not blocked. The second reset member 333 is used to reset the sealing body 332 in the position of blocking the liquid outlet channel 3102. Of course, the sealing body 332 can also be triggered by an increase in the pressure of the liquid matrix.
[0093] In some embodiments, the sealing body 332 may be made of nitrile rubber, EPDM rubber, fluororubber, silicone rubber, fluorosilicone rubber, nylon, polyurethane, engineering plastics, or other sealing devices well known in the art. The shape of the sealing body 332 may be configured according to the sealing location and sealing method.
[0094] In some embodiments, the second reset member 333 may be an elastic member capable of elastic deformation, thereby being able to elastically deform when the seal 332 is triggered, and driving the seal 332 to move based on the elastic deformation when the seal 332 is not triggered. In some embodiments, the second reset member 333 may be a structure supported by a spring or other elastic material.
[0095] Please see Figure 12 , Figure 13 and Figure 14 , Figure 12 for Figure 9 The schematic diagram of the liquid replenishment mechanism 30 in the illustrated embodiment is shown in some other embodiments. Figure 13 for Figure 12 The normally closed on-state valve 33 shown in the embodiment is a schematic diagram of its structure in some embodiments. Figure 14 for Figure 13 The normally closed on-line valve 33 in the illustrated embodiment is shown in a cross-sectional view along line XIV-XIV.
[0096] In some embodiments, the mounting base 331 is used to block the liquid outlet channel 3102 and has a communicating hole 3301 that connects the liquid outlet channel 3102 to the receiving space 3101. The sealing body 332 is used to block the communicating hole 3301 and abuts against the pressing assembly 32, such as the pressing rod 321, to be pushed by the pressing assembly 32, such as the pressing rod 321, to a position where the communicating hole 3301 is not blocked. The second reset member 333 is used to reset the sealing body 332 to the position where the communicating hole 3301 is blocked. The cooperation of the mounting base 331, the sealing body 332, and the second reset member 333 achieves the blocking of the liquid outlet channel 3102. Of course, the sealing body 332 can also be triggered by an increase in the pressure of the liquid matrix.
[0097] In some embodiments, the sealing body 332 may have a connecting channel 3302. The connecting channel 3302 may communicate with the connecting hole 3301 and the liquid outlet channel 3102. The liquid matrix can then enter the connecting channel 3302 from the receiving space 3101, and when the normally closed connecting valve 33, for example the sealing body 332, is triggered, it can enter the connecting hole 3301, and further discharge into the liquid outlet channel 3102 through the connecting channel 3302.
[0098] In some embodiments, the liquid outlet channel 3102 is radially provided with a mounting groove 3105 at one end of the connecting receiving space 3101. The normally closed conducting valve 33, for example, the mounting base 331, is sealed to the inner wall of the mounting groove 3105 to block the liquid outlet channel 3102. In some embodiments, the normally closed conducting valve 33, for example, the mounting base 331, is laser-welded to the inner wall of the mounting groove 3105 to achieve a sealed connection.
[0099] In some embodiments, please refer to Figure 14 and Figure 15 , Figure 15 for Figure 14 The illustrated embodiment shows a schematic diagram of the structure when the mounting base 331 and the sealing body 332 are engaged. Figure 14 In this configuration, the sealing body 332 blocks the connecting hole 3301 of the mounting base 331, preventing the liquid matrix from flowing out through the connecting hole 3301. Simultaneously, the liquid matrix also cannot flow out from the conductive channel 3302 on the sealing body 332. Figure 15 In the middle, the sealing body 332 is made of Figure 14 The position is moved to form a connection hole 3301, which is connected to the liquid outlet channel 3102 through the conduction channel 3302. The liquid matrix can first flow into the liquid outlet channel 3102, then further into the conduction channel 3302, and then into the liquid outlet channel 3102.
[0100] Please refer to the following: Figure 4 , Figure 5 , Figure 7 , Figure 9 Figure 12When the pressing component 32, such as the pressing rod 321, is pressed by the user, it can extend into the receiving space 3101 or the liquid outlet channel 3102, triggering the normally closed conduction valve 33, so that the receiving space 3101 and the liquid outlet channel 3102 are connected. The liquid matrix in the receiving space 3101 will flow into the liquid outlet channel 3102 and further flow into the atomizing core component 22, such as the assembly space 2102. The liquid matrix can enter the core 222, such as the atomizing chamber 2201, through the core body 222, such as the liquid inlet 2207, and be atomized.
[0101] Simultaneously, the pressing component 32, such as the pressing rod 321, extends into the receiving space 3101 or the liquid outlet channel 3102. In some scenarios, this generates positive pressure in the receiving space 3101, pushing the liquid matrix from the receiving space 3101 into the liquid outlet channel 3102. Furthermore, this causes the gas in the liquid outlet channel 3102 and the assembly space 2102 to enter the transmission channel 2202 through the return gas channel 2203 and be discharged outside the atomizing mechanism 20.
[0102] When the user cancels the pressing of the pressing component 32, such as the pressing rod 321, the pressing component 32, such as the pressing rod 321, resets, thereby generating a negative pressure in the receiving space 3101. Driven by the negative pressure, gas enters the transmission channel 2202 and the return channel 2203, and further enters the assembly space 2102 and the return channel 2203 to balance the pressure in the receiving space 3101.
[0103] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
