[0055] The following is a detailed description of the specific implementation of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0056] In the present disclosure, unless otherwise stated, "inside" and "outside" refer to the inside and outside of the corresponding component contour. The terms "first", "second", etc. are used for the purpose of distinguishing different components, and do not have sequentiality and importance. Among them, X in the accompanying drawings is the first direction, and Y is the second direction. In addition, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0057] As Figures 1 - 10As shown in the figure, the present disclosure provides an atomization device, which includes a housing assembly 6, a compression module 5, and a storage member 2. An accommodation cavity 17 is provided inside the housing assembly 6. The housing assembly 6 includes an atomization plate 601 and a communication portion 602. An atomization cavity 7 is formed between the atomization plate 601 and the communication portion 602. The atomization plate 601 is provided with at least one through hole 8. The atomization cavity 7 communicates with the outside through the through hole 8. A compression cavity 1, an input channel 3, and an output channel 4 are formed inside the communication portion 602; the compression module 5 is disposed in the accommodation cavity 17, and the compression module 5 is used to increase or decrease the pressure in the compression cavity 1; the storage member 2 is disposed in the accommodation cavity 17, and a storage cavity for storing the atomization medium to be atomized is provided inside the storage member 2. Among them, the input channel 3 is configured as a one-way channel suitable for the atomization medium to flow from the storage member 2 to the compression cavity 1, and the output channel 4 is configured as a one-way channel suitable for the atomization medium to flow from the compression cavity 1 to the atomization cavity 7.

[0058] Through the above technical solution, the compression module 5 can be used to reduce the pressure in the compression cavity 1. During the process of the pressure in the compression cavity 1 decreasing, the atomization medium in the storage member 2 can be unidirectionally discharged into the compression cavity 1 through the input channel 3; the compression module 5 can increase the pressure in the compression cavity 1. During the process of the pressure in the compression cavity 1 increasing, the compression module 5 can compress the atomization medium inhaled into the compression cavity 1 to unidirectionally discharge the atomization medium into the atomization cavity 7 through the output channel 4, and the atomization medium entering the atomization cavity 7 can be atomized through the through hole 8 on the atomization plate 601 to form an aerosol and be discharged to the outside. Compared with the high-temperature atomization in the related art, the present disclosure realizes the atomization of the atomization medium through pressure change, and does not need to atomize the atomization medium through high temperature, which can effectively avoid the components in the atomization medium from being damaged. In addition, the service life of the atomization device can also be extended.

[0059] In addition, by integrally arranging the compression cavity 1, the input channel 3, and the output channel 4 on the communication portion 602, it is beneficial to simplify the structure of the atomization device, improve the portability of the atomization device, and it is also convenient to process and form the compression cavity 1, the input channel 3, and the output channel 4 on the communication portion 602.

[0060] The present disclosure does not limit the specific structure of the compression module 5. For the convenience of compressing and atomizing the atomization medium, optionally, as Figure 1 shown, the compression module 5 includes a driving mechanism 501 and a compression member 502. The driving mechanism 501 is used to drive the compression member 502 to reciprocate in the compression cavity 1 along the first direction X, so as to inhale the atomization medium in the storage member 2 into the compression cavity 1 through the input channel 3 by reducing the pressure in the compression cavity 1, or discharge the atomization medium in the storage member 2 into the atomization cavity 7 through the output channel 4 by increasing the pressure in the compression cavity 1.

[0061] With such a setting, driving the compression member 502 to reciprocate in the first direction X in the compression chamber 1 by the driving mechanism 501 can reduce the pressure in the compression chamber 1 or increase the pressure in the compression chamber 1. During the process of reducing the pressure in the compression chamber 1, the medium to be atomized in the storage member 2 can be unidirectionally discharged into the compression chamber 1 through the input channel 3; during the process of increasing the pressure in the compression chamber 1, the compression member 502 can compress the medium to be atomized inhaled into the compression chamber 1, so as to unidirectionally discharge the medium to be atomized into the atomization chamber 7 through the output channel 4, and the medium to be atomized entering the atomization chamber 7 can be atomized through the through holes 8 in the atomization plate 601 to form an aerosol and be discharged to the outside.

[0062] For the convenience of fixing the driving mechanism 501, optionally, as Figure 1 shown, the housing assembly 6 further includes a driving mechanism fixing portion 603, and the driving mechanism fixing portion 603 is arranged in the accommodation chamber 17 and is integrally formed with the communication portion 602. Integrally forming the driving mechanism fixing portion 603 and the communication portion 602 can improve the overall strength of the housing assembly 6, and also facilitate the processing and forming of the driving mechanism fixing portion 603 and the communication portion 602, which is convenient for reducing the processing difficulty and improving the processing efficiency.

[0063] For the convenience of installing the driving mechanism 501, optionally, as Figure 7 shown, an installation cavity 9 for accommodating the driving mechanism 501 is arranged inside the driving mechanism fixing portion 603. By providing the installation cavity 9, during assembly, the driving mechanism 501 can be installed and arranged in the accommodation cavity 9.

[0064] As an exemplary implementation manner, the driving mechanism 501 may include a motor 5011 and a transmission assembly 5012, and the motor 5011 is adapted to drive the compression member 502 to reciprocate in the first direction X in the compression chamber) through the transmission assembly 5012. Since the motor 5011 has an output shaft and the output shaft has a certain length in one direction, the installation cavity 9 can extend in the second direction Y to facilitate the installation of the motor 5011.

[0065] It can be understood that, for improving the integration degree of the atomization device, optionally, as Figure 1 shown, the driving mechanism fixing portion 603 and the storage member 2 are arranged at intervals in the accommodation chamber 17 along the first direction X. That is to say, the driving mechanism fixing portion 603 and the storage member 2 can be arranged at intervals along the reciprocating movement direction of the compression member 502. In some embodiments, the driving mechanism fixing portion 603 and the storage member 2 can be arranged at both ends of the compression member 502.

[0066] In the present disclosure, with respect to the configuration of the transmission assembly 5012, in some embodiments, the transmission assembly 5012 may include a rotating shaft, a hinge and an eccentric wheel; the rotating shaft may extend along the second direction Y, and the eccentric wheel is sleeved on the rotating shaft; one end of the hinge is hinged to the eccentric wheel, and the hinge point between the hinge and the eccentric wheel is not located on the rotation axis of the rotating shaft; the other end of the hinge is hinged to the compression element; wherein the rotating shaft is the output shaft of the motor 5011 or a shaft transmission-connected to the output shaft of the motor 5011.

[0067] With such an arrangement, when the rotating shaft is the output shaft of the motor 5011, the transmission component 5012 can form a crank-connecting rod mechanism together with the compressor 502 and the output shaft of the motor 5011, thereby converting the rotational motion of the output shaft of the motor 5011 into the reciprocating linear motion of the compressor 502; when the rotating shaft is an axis drivingly connected to the output shaft of the motor 5011, the output shaft of the motor 5011 can drive the rotating shaft to rotate coaxially, and the transmission component 5012 can form a crank-connecting rod mechanism together with the compressor 502 and the rotating shaft, thereby converting the rotational motion of the output shaft of the motor 5011 into the reciprocating motion of the compressor 502.

[0068] In order to facilitate the function that the medium to be atomized in the storage element 2 can only flow from the storage element 2 to the compression chamber 1 in one direction through the input channel 3, and the function that the medium to be atomized in the compression chamber 1 can only flow from the compression chamber 1 to the atomization chamber 7 in one direction through the output channel 4, optionally, as Figure 1 As shown, the atomization device also includes a first one-way connecting structure 10 and a second one-way connecting structure 11. The first one-way connecting structure 10 is suitable for connecting or cutting off the input channel 3, so that the input channel 3 is opened or closed; the second one-way connecting structure 11 is suitable for connecting or cutting off the output channel 4, so that the output channel 4 is opened or closed.

[0069] In the present disclosure, there are many ways to set the first one-way connecting structure 10 and the second one-way connecting structure 11, as long as it can meet the requirements that when the pressure in the compression chamber 1 decreases, the first one-way connecting structure 10 can connect the input channel 3 and the second one-way connecting structure 11 can cut off the output channel 4, and when the pressure in the compression chamber 1 increases, the first one-way connecting structure 10 can cut off the input channel 3 and the second one-way connecting structure 11 can connect the output channel 4.

[0070] As an exemplary implementation, Figure 1 and Figure 2As shown, the input channel 3 includes a first section 301 and a second section 302 that are connected. The first section 301 extends along the first direction X, and the second section 302 extends along the second direction Y. The compression member 502 reciprocates along the first direction X. Herein, the first direction X and the second direction Y are orthogonal. In other words, the extending direction of the second section 302 forms a 90° angle with the reciprocating movement direction of the compression member 502, which is beneficial to improving the integration degree of the atomization device.

[0071] As Figure 2 shown, the first one-way connection structure 10 includes a first valve plate 1001 disposed in the compression chamber 1. The first valve plate 1001 covers the opening of the first section 301 for communicating with the compression chamber 1. During the process that the compression member 502 reciprocates along the first direction X to increase or decrease the pressure in the compression chamber 1, the extending direction of the first section 301 and the reciprocating movement direction of the compression member 502 are set to be the same direction, and the first valve plate 1001 can quickly respond to the action of the compression member 502. That is to say, during the process that the pressure in the compression chamber 1 decreases, the to-be-atomized medium in the storage member 2 can be unidirectionally discharged into the compression chamber 1 through the input channel 3. Based on the fact that the first section 301 extends along the first direction X, the to-be-atomized medium in the first section 301 can flow along the first direction X, so that the first valve plate 1001 will be pushed open by the to-be-atomized medium in the first section 301 along the first direction X to be able to conduct the input channel 3, thereby enabling the to-be-atomized medium in the storage member 2 to smoothly enter the compression chamber 1. During the process that the pressure in the compression chamber 1 increases, the compression member 502 can compress the to-be-atomized medium inhaled into the compression chamber 1 along the first direction X, so that the first valve plate 1001 will be pushed by the to-be-atomized medium in the compression chamber 1 along the first direction X to cover the opening of the first section 301 communicating with the compression chamber 1 to be able to cut off the input channel 3, thereby preventing the to-be-atomized medium in the compression chamber 1 from being discharged into the storage member 2 through the input channel 3.

[0072] Optionally, as Figure 1 shown, the first one-way connection structure 10 may further include a first mounting member. The first valve plate 1001 is located in the compression chamber 1. The first valve plate 1001 has a first through hole and a first blocking portion. The first blocking portion is used to block the opening of the first section 301 communicating with the compression chamber 1. That is to say, the first blocking portion can separate the compression chamber 1 and the input channel 3. In addition, a first mounting hole is provided in the connecting portion 602, and the first mounting member passes through the first through hole and is inserted into the first mounting hole. Here, the first mounting member may be a plug rod and can be press-fitted in the first mounting hole. And, the first blocking portion is arranged to be moved away from the opening of the first section 301 communicating with the compression chamber 1 by the to-be-atomized medium from the storage member 2 during the process that the compression member 502 moves in the direction of reducing the pressure in the compression chamber 1.

[0073] Based on the above settings, when the compression member 502 moves in the direction of reducing the pressure in the compression chamber 1, the pressure in the compression chamber 1 decreases and a negative pressure can be formed in the compression chamber 1. A pressure difference is formed between the compression chamber 1 separated by the first valve piece 1001 and the input channel 3. The medium to be atomized in the storage member 2 can exert a squeezing force on the first valve piece 1001 via the input channel 3. When the pressure in the compression chamber 1 continues to decrease, the first blocking portion can be displaced from the opening where the first section 301 communicates with the compression chamber 1 under the squeezing of the medium to be atomized in the input channel 3, so that the opening where the first section 301 communicates with the compression chamber 1 is exposed, and the medium to be atomized in the input channel 3 can enter the compression chamber 1 through the opening where the first section 301 communicates with the compression chamber 1.

[0074] Specifically, as Figure 1 and Figure 2 shown, the first blocking portion is located in the compression chamber 1. The first blocking portion is used to block one side of the opening where the first section 301 communicates with the compression chamber 1 and abuts against the communicating portion 602. And the first blocking portion can be a metal sheet or a rubber sheet that can elastically deform. That is to say, when the compression member 502 moves in the direction of reducing the pressure in the compression chamber 1, under the continuous squeezing of the medium to be atomized in the input channel 3, the first blocking portion can elastically deform to expose the opening where the first section 301 communicates with the compression chamber 1, so that the medium to be atomized can enter the compression chamber 1 and fill the entire compression chamber 1; when the compression member 502 moves in the direction of increasing the pressure in the compression chamber 1, the compression member 502 can squeeze the medium to be atomized in the compression chamber 1, the first blocking portion can return to its original state, and under the squeezing action of the medium to be atomized, it abuts against the communicating portion 602, so that the first blocking portion can block the opening where the first section 301 communicates with the compression chamber 1 to separate the compression chamber 1 and the input channel 3.

[0075] It can be understood that in order to enable the first blocking portion to quickly respond to the movement of the compression member 502, optionally, the opening where the first section 301 communicates with the compression chamber 1 is arranged relative to the movement direction of the compression member 502, and the first blocking portion is also arranged relative to the movement direction of the compression member 502.

[0076] Based on the above setting of the first one-way connection structure 10, optionally, the output channel 4 extends along the second direction Y. The second one-way connection structure 11 includes a second valve plate 1101 disposed in the atomization chamber 7, and the second valve plate 1101 covers the opening of the output channel 4 for communicating with the atomization chamber 7. Wherein, the output channel 4 and the second section 302 are arranged in a staggered manner in the first direction X. That is to say, the second valve plate 1101 can separate the output channel 4 and the atomization chamber 7, that is, the second valve plate 1101 can separate the compression chamber 1 and the atomization chamber 7. During the process of the pressure in the compression chamber 1 decreasing, since the second valve plate 1101 is disposed in the atomization chamber 7, the second valve plate 1101 will be squeezed by the air pressure in the atomization chamber 7 and cover the opening of the output channel 4 for communicating with the atomization chamber 7, so as to be able to cut off the output channel 4, so that the medium to be atomized in the compression chamber 1 will not be discharged to the atomization chamber 7 through the output channel 4. During the process of the pressure in the compression chamber 1 increasing, the compression member 502 squeezes the medium to be atomized in the compression chamber 1, so that the second valve plate 1101 will be opened under the squeezing action of the medium to be atomized, so as to expose the opening of the output channel 4 for communicating with the atomization chamber 7, so that the medium to be atomized in the compression chamber 1 can be discharged to the atomization chamber 7 through the output channel 4.

[0077] Optionally, as Figure 1 shown, the second one-way connection structure 11 may include a second mounting member. A second mounting hole is provided on the end face of the outlet of the communication part 602 where the opening of the output channel 4 for communicating with the atomization chamber 7 is located. The second valve plate 1101 is disposed on the end face. The second valve plate 1101 has a second through hole and a second blocking portion, and the second blocking portion is used to block the opening of the output channel 4 for communicating with the atomization chamber 7. That is to say, the second blocking portion can separate the compression chamber 1 and the atomization chamber 7. The second mounting member passes through the second through hole and is inserted into the second mounting hole. Here, the second mounting member may be a plug rod and may be in interference fit in the second mounting hole. And, the second blocking portion is arranged to be able to be moved away from the opening of the output channel 4 for communicating with the atomization chamber 7 by the medium to be atomized from the compression chamber 1 during the process of the compression member 502 moving in the direction of increasing the pressure in the compression chamber 1.

[0078] Based on the above setting, when the compression member 502 moves in the direction of increasing the pressure in the compression chamber 1, the pressure in the compression chamber 1 increases and the compression member 502 squeezes the medium to be atomized in the compression chamber 1. When the pressure in the compression chamber 1 continues to increase, the second blocking portion can be moved away from the opening of the output channel 4 for communicating with the atomization chamber 7 under the squeezing of the medium to be atomized in the compression chamber 1, so that the opening of the output channel 4 for communicating with the atomization chamber 7 is exposed, and the medium to be atomized in the compression chamber 1 can be discharged through the opening of the output channel 4 for communicating with the atomization chamber 7 and atomized through the atomization chamber 7.

[0079] Specifically, as Figure 1 andFigure 2 As shown, the second blocking portion is located outside the output channel 4. The second blocking portion is used to block one side of the opening of the output channel 4 communicating with the atomization chamber 7, and the second blocking portion abuts against the outlet end face. Moreover, the second blocking portion can be a metal sheet or a rubber sheet that can elastically deform. That is to say, when the compression member 502 moves in the direction of increasing the pressure in the compression chamber 1, under the continuous extrusion of the medium to be atomized in the compression chamber 1, the second blocking portion can elastically deform to expose the opening of the output channel 4 communicating with the atomization chamber 7, so that the medium to be atomized can be atomized via the atomization chamber 7; when the compression member 502 moves in the direction of reducing the pressure in the compression chamber 1, the pressure in the compression chamber 1 decreases and a negative pressure can be formed. The second blocking portion abuts against the outlet end face under the external air pressure and returns to its original state, so that the second blocking portion can block the opening of the output channel 4 communicating with the atomization chamber 7 to separate the compression chamber 1 and the atomization chamber 7.

[0080] In the present disclosure, in combination with the first one-way communication structure 10 and the second one-way communication structure 11 of this embodiment, during the process of the pressure in the compression chamber 1 decreasing, the first valve plate 1001 will be opened by the extrusion force of the medium to be atomized in the first section 301 along the first direction X to conduct the input channel 3, while the second valve plate 1101 will be covered on the opening of the output channel 4 communicating with the atomization chamber 7 under the extrusion of the air pressure in the atomization chamber 7 to block the output channel 4, so that the medium to be atomized in the storage member 2 can smoothly enter the compression chamber 1, and the medium to be atomized in the compression chamber 1 will not be discharged from the output channel 4 to the atomization chamber 7; during the process of the pressure in the compression chamber 1 increasing, the compression member 502 can compress the medium to be atomized inhaled into the compression chamber 1, so that the first valve plate 1001 will be covered on the opening of the first section 301 communicating with the compression chamber 1 by the extrusion force of the medium to be atomized in the compression chamber 1 along the first direction X to block the input channel 3, while the second valve plate 1101 will be opened under the extrusion of the medium to be atomized to expose the opening of the output channel 4 communicating with the atomization chamber 7 to conduct the output channel 4, so that the medium to be atomized in the compression chamber 1 can be discharged to the atomization chamber 7 via the output channel 4 for atomization, and the medium to be atomized in the compression chamber 1 will not be discharged into the storage member 2 via the input channel 3.

[0081] As another exemplary implementation manner, the first one-way communication structure 10 is the first one-way valve 1002 disposed in the input channel 3, and the second one-way communication structure 11 is the second one-way valve 1102 disposed in the output channel 4. Thus, during the process of the pressure in the compression chamber 1 decreasing, the first one-way valve 1002 can conduct the input channel 3, and the second one-way valve 1102 can cut off the output channel 4, so that the medium to be atomized in the storage member 2 can be inhaled into the compression chamber 1 via the input channel 3, and the medium to be atomized in the compression chamber 1 will not be discharged to the atomization chamber 7 through the output channel 4; during the process of the pressure in the compression chamber 1 increasing, the first one-way valve 1002 can cut off the input channel 3, and the second one-way valve 1102 can conduct the output channel 4, so that the medium to be atomized in the compression chamber 1 can be discharged to the atomization chamber 7 for atomization through the output channel 4, and the medium to be atomized in the compression chamber 1 will not be discharged into the storage member 2 through the input channel 3.

[0082] Here, both the input channel 3 and the output channel 4 extend along the second direction Y, and the input channel 3 and the output channel 4 are arranged opposite to each other in the second direction Y, which can enable the first one-way valve 1002 and the second one-way valve 1102 to receive substantially the same acting force during the process of the pressure change in the compression chamber 1.

[0083] It can be understood that in the present disclosure, the first one-way valve 1002 may include a first screw, a first spring, and a first sphere, and the second one-way valve 1102 may include a second screw, a second spring, and a second sphere. Among them, the first screw is axially penetrated with a first communication hole 8, and the second screw is axially penetrated with a second communication hole 8. Specifically, a first thread section may be provided in the input channel 3 of the communication part 602 along the second direction Y, so that the first screw is threadedly connected to the communication part 602 through the first thread section to install the first screw in the input channel 3. The first end of the first communication hole 8 is communicated with the opening where the input channel 3 is communicated with the storage member 2, and the second end of the first communication hole 8 is communicated with the opening where the input channel 3 is communicated with the compression chamber 1. The first sphere is disposed in the input channel 3 and is disposed at a position close to the second end of the first communication hole 8. The first spring extends along the second direction Y and is disposed in the input channel 3. One end of the first spring abuts against the communication part 602, and the other end of the first spring abuts against the first sphere, so that the first sphere can block the second end of the first communication hole 8.

[0084] Similarly, a second threaded section may be provided along the second direction Y in the output passage 4 of the connecting portion 602, such that the second screw is threadedly connected to the connecting portion 602 through the second threaded section to mount the second screw in the output passage 4. The first end of the second communication hole 8 communicates with the opening where the output passage 4 communicates with the compression chamber 1, and the second end of the second communication hole 8 communicates with the opening where the output passage 4 communicates with the atomization chamber 7. The second sphere is disposed in the output passage 4 and is disposed near the opening where the input passage 3 communicates with the compression chamber 1. The second spring extends along the second direction Y and is disposed in the output passage 4. One end of the second spring abuts against the second threaded section, and the other end of the second spring abuts against the second sphere, such that the second sphere can block the opening where the input passage 3 communicates with the compression chamber 1.

[0085] Combining the structures of the above-mentioned first one-way valve 1002 and second one-way valve 1102, during the process of the pressure in the compression chamber 1 decreasing, the medium to be atomized in the liquid storage chamber can squeeze the first sphere, such that the first sphere can squeeze the first spring to compress, so as to expose the second end of the first communication hole 8. The second end of the first communication hole 8 communicates with the opening where the input passage 3 communicates with the compression chamber 1, thereby enabling the input passage 3 to be conducted. The negative pressure generated in the compression chamber 1 can suck the second sphere, such that the second sphere can block the opening where the input passage 3 communicates with the compression chamber 1, thereby truncating the output passage 4, so that the medium to be atomized in the storage member 2 can be sucked into the compression chamber 1 through the input passage 3, and the medium to be atomized in the compression chamber 1 will not be discharged to the atomization chamber 7 through the output passage 4; during the process of the pressure in the compression chamber 1 increasing, the medium to be atomized in the compression chamber 1 can squeeze the first sphere to block the second end of the first communication hole 8 and truncate the communication between the second end of the first communication hole 8 and the opening where the input passage 3 communicates with the compression chamber 1, thereby enabling the input passage 3 to be truncated. The medium to be atomized in the compression chamber 1 can squeeze the second sphere, such that the second sphere can squeeze the second spring to compress, so as to expose the opening where the input passage 3 communicates with the compression chamber 1. The first end of the second communication hole 8 communicates with the opening where the output passage 4 communicates with the compression chamber 1, thereby enabling the output passage 4 to be conducted, such that the medium to be atomized in the compression chamber 1 can be discharged to the atomization chamber 7 for atomization through the output passage 4, and the medium to be atomized in the compression chamber 1 will not be discharged into the storage member 2 through the input passage 3.

[0086] Optionally, the connecting portion 602 further includes a guiding hole that extends along the first direction X and communicates with the compression chamber 1. The compression member 502 is slidably fitted in the guiding hole along the first direction X. That is to say, the guiding hole can limit the reciprocating movement direction of the compression member 502, and can limit the reciprocating movement direction of the compression member 502 to the first direction. Here, since the guiding hole communicates with the compression chamber 1, the guiding hole can also become a part of the compression chamber 1.

[0087] It can be understood that, in order to improve the airtightness of the compression chamber 1, optionally, a sealing structure is provided between the compression member 502 and the guiding hole to reduce the influence of the external air pressure on the compression chamber 1 and prevent the leakage of the medium to be atomized in the compression chamber 1. As an exemplary embodiment, the seal may be a rubber sealing ring, which can be sleeved outside the compression member 502 and in interference fit with the guiding hole. It should be noted that the interference fit between the rubber sealing ring and the guiding hole will not affect the movement of the compression member 502.

[0088] Optionally, the atomizing device includes an air outlet 12, and the air outlet 12 is communicated with the through hole 8. The connecting portion 602 is provided with a first assembling boss 13, and the first assembling boss 13 extends along the second direction Y towards the air outlet 12 and is partially located in the air outlet 12. The part of the output channel 4 close to the atomizing plate 601 is located in the first assembling boss 13. An atomizing chamber 7 is defined between one end of the first assembling boss 13 far from the compression chamber 1 and the atomizing plate 601. With such a setting, the medium to be atomized forms an aerosol after being atomized by the through hole 8 of the atomizing plate 601 and is discharged towards the air outlet 12 so that the user can suck through the air outlet 12.

[0089] It can be understood that, in order to facilitate the installation of the storage member 2 on the connecting portion 602, optionally, the connecting portion 602 is provided with a second assembling boss 14, and the second assembling boss 14 extends along the second direction Y away from the compression chamber 1; the part of the input channel 3 close to the liquid storage member is located in the second assembling boss 14; the storage member 2 is provided with a connecting sleeve 15, and the connecting sleeve 15 is sleeved outside the second assembling boss 14 to communicate the input channel 3 with the storage chamber in the storage member 2.

[0090] In order to facilitate the disassembly, assembly and processing of the housing assembly 6, optionally, the housing assembly 6 includes an upper cover 604, a middle shell 605 and a lower cover 606. The upper cover 604, the middle shell 605 and the lower cover 606 are sequentially spliced to jointly enclose an accommodation chamber 17. Moreover, by adopting a segmented design for the housing assembly 6, it is convenient to process the internal structures of the upper cover 604, the middle shell 605 and the lower cover 606 respectively. As an exemplary embodiment, the upper cover 604, the middle shell 605 and the lower cover 606 are all provided with screw holes. The upper cover 604 can be connected to the middle shell 605 by screws, and the middle shell 605 can also be connected to the lower cover 606 by screws.

[0091] Optionally, the connecting portion 602 is fixed to the middle shell 605, so that the connecting portion 602 can be arranged at the middle position of the atomizing device to have sufficient space to form the compression chamber 1, the input channel 3 and the output channel 4. The atomizing plate 601 is arranged on the upper cover 604 or the middle shell 605, so that the aerosol formed by atomizing the medium to be atomized through the through hole 8 of the atomizing plate 601 can be smoothly discharged to the outside for the user to suck.

[0092] Optionally, the connecting part 602 and the middle shell 605 are integrally formed so that the connecting part 602 and the middle shell 605 form a whole, improving the structural strength of the connecting part 602 and the middle shell 605, facilitating the processing of the connecting part 602 and the middle shell 605, and reducing the use of connecting parts.

[0093] To further facilitate the user to suck the aerosol formed by atomizing the atomization medium, optionally, the upper cover 604 includes a main body 6041 and an air outlet pipe 6042. The main body 6041 is a sleeve with one end open. The main body 6041 includes an annular side wall 60411 and an end wall 60412. The air outlet pipe 6042 and the end wall 60412 define an air outlet 12. That is to say, the open end of the main body 6041 can be arranged on the end wall 60412. The aerosol formed by atomizing the atomization medium through the through hole 8 of the atomization plate 601 can be discharged into the air outlet pipe 6042 through the open end of the main body 6041, so that the user can suck the aerosol through the air outlet pipe 6042. In the present disclosure, the open end of the main body 6041 can directly form the atomization plate 601 with the through hole 8, or an opening is formed on the main body 6041 to form the open end, and the through hole 8 of the atomization plate 601 is communicated with the opening.

[0094] Optionally, the lower cover 606 is provided with a space for accommodating the power source 16, and the power source 16 is the power source for supplying power to the compression module 5, so as to improve the portability of the atomization device. As an exemplary implementation manner, the power source 16 can be a power source for supplying power to the driving mechanism 501.

[0095] In the present disclosure, in order to facilitate the control of the compression module 5, that is, in order to facilitate the control of the electrical connection or disconnection between the power source 16 and the driving mechanism 501. Optionally, as Figure 1 shown, the atomization device further includes a power source 16 and a control unit 18. The control unit 18 is electrically connected to the power source 16; the control unit 18 can control the electrical connection or disconnection between the power source 16 and the driving mechanism 501 (such as the motor 5011 of the driving mechanism 501), so as to conduct or disconnect the transmission connection between the driving mechanism 501 and the compression member 502. With such a setting, the power source 16 can supply power to the driving mechanism 501, and the control unit 18 controls the electrical connection or disconnection between the power source 16 and the driving mechanism 501 to realize the control of the driving mechanism 501.

[0096] In the present disclosure, there are many forms of setting for the control unit 18, as long as it can satisfy that the control unit 18 can control the electrical connection or disconnection between the power source 16 and the driving mechanism 501.

[0097] As an exemplary implementation manner, as Figure 3As shown in the figure, the control unit 18 may include a controller 1801 and an air flow sensor 1802. The input end of the controller 1801 is electrically connected to the air flow sensor 1802, and the output end of the controller 1801 is electrically connected to the power supply 16. An air inlet 19 is provided on the atomization device, and the air inlet 19 is communicated with the air outlet 12. The air flow sensor 1802 is used to monitor the change of the air pressure value at the air inlet 19, or the air flow sensor 1802 is used to monitor the change of the air pressure value at the air outlet 12; the controller 1801 is used to control the electrical conduction or disconnection between the power supply 16 and the driving mechanism 501 according to the change of the air pressure value.

[0098] With such a setting, when inhaling air from the air outlet 12, the air pressure value at the air outlet 12 will change. Since the air outlet 12 and the air inlet 19 are communicated, the air pressure value at the air inlet 19 will also change accordingly. Whether the air flow sensor 1802 detects the change of the air pressure value at the air inlet 19 or the change of the air pressure value at the air outlet 12, the air flow sensor 1802 can detect the same change of the air pressure value. Thus, the air flow sensor 1802 can transmit the detected air pressure value change signal to the controller 1801, so that the controller 1801 can control the electrical conduction between the power supply 16 and the driving mechanism 501. When stopping inhaling air from the air outlet 12, the air pressure value at the air outlet 12 can be maintained stable, and the air pressure value at the air inlet 19 can also be maintained stable accordingly. The air flow sensor 1802 does not detect the change of the air pressure value at the air outlet 12 or the air inlet 19, so that the controller 1801 can control the electrical disconnection between the power supply 16 and the driving structure, so as to start or close the driving mechanism 501.

[0099] As another exemplary embodiment, as Figure 1 shown, the control unit 18 includes a push-button switch 1803. The push-button switch 1803 is electrically connected to the power supply 16 and is adapted to respond to user operations to achieve the electrical conduction or disconnection between the power supply 16 and the driving mechanism 501. Thus, when the user presses the push-button switch 1803, the electrical conduction between the power supply 16 and the driving mechanism 501 can be achieved, so as to start the driving mechanism 501; when the user presses the push-button switch 1803 again, the electrical disconnection between the power supply 16 and the driving mechanism 501 can be achieved, so as to close the driving mechanism 501.

[0100] As Figure 9 shown, in the present disclosure, there is no limit to the number of through holes 8 on the atomization plate 601. The number of through holes 8 can be one or multiple. The specific number of through holes 8 is determined according to the atomization amount to be output. As an exemplary embodiment, as Figure 6 shown, the number of through holes 8 can be multiple. The multiple through holes 8 are evenly arranged on the atomization plate 601. The multiple evenly arranged through holes 8 can increase the output amount of the aerosol and can also make the aerosol diffuse uniformly to the outside.

[0101] In addition, in the present disclosure, there is no limitation on the shape of the through-hole 8, as long as the medium to be atomized output by the output channel 4 can be atomized through the through-hole 8. As an exemplary embodiment, as Figure 9 shown, the through-hole 8 can be a round hole, the aperture of the through-hole 8 is 0.01 mm to 0.1 mm, and the minimum distance between two adjacent through-holes 8 in the radial direction of the through-hole 8 is greater than the radius of the through-hole 8. For example, the aperture of the through-hole 8 can be set to 0.1 mm, and correspondingly, the minimum distance between two adjacent through-holes 8 in the radial direction of the through-hole 8 can be 0.05 mm.

[0102] As another exemplary embodiment, as Figure 10 shown, the through-hole 8 can be a square hole, the hole width of the through-hole 8 is 0.01 mm to 0.1 mm, and the minimum distance between two adjacent through-holes 8 is greater than the hole width of the through-hole 8. For example, the hole width of the through-hole 8 can be set to 0.01 mm, and correspondingly, the minimum distance between two adjacent through-holes 8 can be 0.05 mm.

[0103] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0104] In addition, it should be noted that, in the case of no contradiction, the various specific technical features described in the above specific embodiments can be combined in any suitable manner. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination manners.

[0105] Furthermore, any combination can be made between various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
