Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomizer, in particular to an atomization assembly and an atomizer. BACKGROUND

[0002] The atomizer is an electronic product simulating a cigarette. Most of the atomizers currently include an atomization assembly and an atomization main body, and the atomization assembly stores an aerosol substrate. When the atomization assembly and the atomization main body are connected, a battery in the atomization main body is electrically connected with the atomization assembly in the atomization assembly, the atomization assembly heats the aerosol substrate in the atomization assembly and releases the aerosol substrate as an aerosol.

[0003] In the design, when the atomization assembly and the atomization main body are assembled into one, a push rod of the atomization main body extends into the liquid outlet hole and pushes the sealing plug to move, thereby opening the liquid outlet hole and releasing the aerosol substrate. However, in the design, the aerosol substrate is prone to leaking along the push rod into the atomization cavity and causing liquid leakage. CONTENT OF THE UTILITY MODEL

[0004] The present application provides an atomization assembly and an atomizer to solve the problem of liquid leakage when the atomization assembly is assembled to the atomization main body in the prior art.

[0005] In one aspect, the present application provides an atomization assembly, which further includes an atomization main body, and the atomization assembly includes:

[0006] an inner shell having a liquid storage cavity for storing atomization liquid, the inner shell being provided with spaced-apart guide holes and a liquid outlet hole on one side of the atomization assembly in an axial direction;

[0007] a piston assembly movably arranged in the liquid storage cavity, the piston assembly being provided with a guide portion and a sealing portion, the guide portion being guided and matched with the guide holes, and the sealing portion being used to open or close the liquid outlet hole.

[0008] When the atomization assembly is used, the piston assembly is driven to move under the action of an external force, i.e., the guide portion is pushed to move along the guide holes. In this process, the guide portion is always sealed at the guide holes and guided and matched with the guide holes, i.e., the piston assembly can be pushed without contacting the atomization liquid. Through the separable design of the liquid outlet hole and the sealing portion and the guiding and matching of the guide portion with the guide holes, the liquid outlet hole can be opened or closed without contacting the atomization liquid when the atomization assembly is used, the leakage of the atomization liquid that may occur when the liquid outlet hole is controlled is prevented, and the user experience is ensured.

[0009] In one possible implementation, the piston assembly includes:

[0010] a piston support movable in the axial direction of the atomization assembly, the guide portion and the sealing portion being arranged in the piston support.

[0011] The introduction of the piston support makes the piston assembly more stable during movement, reduces the risk of leakage caused by deviation or shaking, and the close fit of the guide part and the guide hole and the accurate control of the plugging part on the liquid outlet hole make the outflow of the atomized liquid more uniform and controllable.

[0012] In a possible implementation, the piston support divides the liquid storage cavity into a first chamber and a second chamber,

[0013] The piston support is provided with a communication hole communicating the first chamber and the second chamber, and the guide part and the plugging part are located on the side of the piston support facing the second chamber.

[0014] By dividing the liquid storage cavity into two chambers and setting a communication hole to control the flow of atomized liquid, the control of the amount of atomized liquid flowing out each time is realized, which helps to reduce the waste and leakage of atomized liquid, and also optimizes the distribution and flow path of the atomized liquid in the liquid storage cavity, which helps to improve the atomization effect and improve the user experience.

[0015] In a possible implementation, the piston assembly further comprises an elastic reset member, which is arranged between the piston support and the inner shell.

[0016] By introducing the elastic reset member, the automatic reset function of the piston support after movement is realized, ensuring that the piston assembly can return to the preset position after each use, and improving the automation degree of the atomizer.

[0017] In a possible implementation, the side wall of the inner shell opposite to the guide hole is provided with a first fixing groove, and the piston support is provided with a second fixing groove opposite to the first fixing groove, one end of the elastic reset member is fixed in the first fixing groove, and the other end is fixed in the second fixing groove.

[0018] By fixing one end of the elastic reset member in the first fixing groove of the inner shell and the other end in the second fixing groove of the piston support, the stable installation of the elastic reset member is realized, ensuring the accurate reset of the piston support after movement, and improving the stability and reliability of the entire piston assembly.

[0019] In a possible implementation, the side wall of the inner shell is provided with a sliding rail extending along the axial direction of the atomization assembly, and the piston support is provided with a sliding convex part which is in sliding fit with the sliding rail.

[0020] By setting the sliding rail on the side wall of the inner shell and the sliding convex part on the side wall of the piston support, stable sliding fit between the piston support and the inner shell is realized, improving the accuracy and stability of the movement of the piston assembly, and also helping to reduce wear and leakage risk.

[0021] In a possible implementation, the piston assembly further comprises:

[0022] a first sealing plug fixedly arranged on the piston support, the first sealing plug being adapted to the guide hole, and the first sealing plug constituting the guide portion;

[0023] a second sealing plug fixedly arranged on the piston support, the second sealing plug being adapted to the liquid outlet hole, and the second sealing plug constituting the blocking portion.

[0024] By arranging the first sealing plug and the second sealing plug, the sealing performance and the stability of the oil outlet amount of the piston assembly are improved, which helps to prevent the leakage of the atomized liquid or gas and ensures the normal operation of the atomization assembly and the use safety of the user.

[0025] In a possible implementation, the first sealing plug and the second sealing plug are integrally formed.

[0026] The integrally formed first sealing plug and second sealing plug are more compact in structure, improve the structural stability of the atomization assembly, and also simplify the manufacturing process. In addition, the integrally formed first sealing plug and second sealing plug are more uniform in material and structure, which can provide better sealing effect, ensure the normal operation of the atomization assembly and the use safety of the user.

[0027] In a possible implementation, the height of the guide portion is higher than the height of the blocking portion.

[0028] In this way, when the blocking portion opens or closes the liquid outlet hole, the guide portion is always located in the guide hole.

[0029] In a possible implementation, the liquid outlet hole is designed as an open end facing the blocking portion, the cross section of one end of the blocking portion facing the liquid outlet hole gradually decreases, and the liquid outlet hole is adapted to the blocking portion.

[0030] This design makes the blocking portion more smoothly block into the liquid outlet hole when the blocking portion moves towards the liquid outlet hole. In addition, the open end design of the liquid outlet hole also provides a flow direction for the oil liquid, improving the smoothness of the oil liquid outflow.

[0031] In a possible implementation, the atomization assembly further comprises an outer shell, the outer shell having a containing cavity and a smoke outlet communicating with the containing cavity;

[0032] The inner shell is arranged in the containing cavity, and part of the outer wall of the inner shell is spaced apart from the inner wall of the outer shell to jointly define a flue communicating with the smoke outlet.

[0033] Thus, when the atomized liquid flows out and is directly absorbed by the liquid suction member, the atomization main body controls the liquid suction member to atomize the atomized liquid into gas, and then the flue defined by the inner shell and the outer shell flows out, thereby realizing the use of the atomizer.

[0034] In a possible implementation, the inner shell comprises:

[0035] The shell main body defines the liquid storage cavity, and the shell main body is provided with an opening on a side of the atomization assembly in an axial direction and away from the smoke outlet;

[0036] The bottom cover covers the opening, and the guide hole and the liquid outlet hole both penetrate the bottom cover.

[0037] The opening of the shell main body is covered by the bottom cover, thereby ensuring the sealing of the liquid storage cavity and preventing the atomized liquid from leaking. In addition, the split design of the shell main body and the bottom cover makes the assembly process simpler and more convenient, and facilitates subsequent maintenance and replacement.

[0038] In a possible implementation, the inner shell further comprises a first sealing member arranged on a circumferential side of the bottom cover to seal a gap between the bottom cover and the shell main body.

[0039] The first sealing member can seal the gap between the bottom cover and the shell main body, thereby preventing the atomized liquid from leaking and improving the overall sealing performance of the atomization assembly.

[0040] In a possible implementation, an edge of the bottom cover is further provided with an air pressure balance hole penetrating in the axial direction of the atomization assembly, and the liquid storage cavity has a liquid outlet state and a closed state. In the liquid outlet state, the first sealing member opens the air pressure balance hole, and in the closed state, the first sealing member closes the air pressure balance hole.

[0041] Through the cooperation of the air pressure balance hole and the first sealing member, the internal air pressure of the liquid storage cavity and the external air pressure are balanced, thereby avoiding the leakage of the atomized liquid or the poor atomization effect caused by the change of the air pressure. In addition, the first sealing member can close the air pressure balance hole in the closed state, thereby preventing the leakage of the atomized liquid or air and improving the sealing performance of the atomization assembly.

[0042] In a possible implementation, the inner shell comprises a side wall and a top wall, the top wall is opposite to the smoke outlet, and a part of the flue is located between the side wall and the inner wall of the outer shell, and another part of the flue is located between the top wall and the inner wall of the outer shell.

[0043] Thus, when the atomized liquid flows out and is directly absorbed by the liquid suction member, the atomization main body controls the liquid suction member to atomize the atomized liquid into gas, and then the flue defined by the inner shell and the outer shell flows out, thereby realizing the use of the atomizer.

[0044] In a possible implementation, a periphery of the smoke outlet is provided with a flow guide part extending towards the top wall, the flow guide part is in abutment with the top wall, and the flow guide part separates the flue from a space around the smoke outlet.

[0045] Through the guidance of the flow guide part, the concentration and order of the smoke flowing out of the smoke outlet are ensured, the atomization effect and taste of the atomizer are improved, and in addition, the diffusion and leakage of the smoke around the smoke outlet are prevented, and the sealing performance of the atomizer is improved.

[0046] In a possible implementation, the atomization assembly further includes a second sealing member provided between the top wall and the flow guide part.

[0047] The second sealing member further enhances the sealing between the top wall and the flow guide part, ensures that the smoke can flow out of the smoke outlet more concentratedly and orderly, and improves the atomization effect and taste of the atomizer.

[0048] In a possible implementation, the atomization assembly further includes a liquid suction member provided at an end of the liquid outlet hole away from the liquid storage cavity, the liquid suction member is provided with a relief hole for avoiding the guide part, and the guide part passes through the relief hole and is used to cooperate with the atomization main body.

[0049] By introducing the liquid suction member and designing the relief hole to cooperate with the connection of the guide part and the atomization main body, the stability of the liquid supply of the atomization assembly and the reliability of the use of the atomization assembly are improved, and the user experience is ensured.

[0050] In a possible implementation, the shell further cooperates with the inner shell to define an atomization cavity, the atomization cavity is located at a side of the inner shell away from the smoke outlet, the liquid suction member is located in the atomization cavity,

[0051] In a state where the atomization main body is connected with the atomization assembly, the atomization main body blocks the atomization cavity.

[0052] The design of the atomization cavity enables the atomization process to be carried out in a relatively closed space, which is conducive to controlling the temperature and pressure in the atomization process, thereby improving the efficiency and stability of the atomization, in addition, the design of the atomization main body blocking the atomization cavity enables the smoke to flow out of the smoke outlet smoothly, avoids the accumulation and leakage of the smoke in the atomization cavity, and improves the user experience.

[0053] Another aspect of the present application also provides an atomizer, comprising:

[0054] The atomization assembly in any of the above possible implementations;

[0055] An atomization main body is detachably connected with the atomization assembly, and is used to drive the piston assembly to move to open the liquid outlet hole.

[0056] Through the design of the piston assembly, the supply amount of atomized liquid can be controlled, the atomization efficiency and stability are improved, in addition, the stability and reliability of the atomizer during use are improved, the risk of liquid leakage is reduced, and the user experience is improved.

[0057] In a possible implementation, the atomization main body comprises a push rod, and the push rod is used to drive the piston assembly to move.

[0058] By introducing the push rod as a component for driving the piston assembly to move, the atomization efficiency of the atomizer and the reliability of the use of the atomization main body are improved.

[0059] In a possible implementation, the atomization main body comprises an air inlet channel, and the air inlet channel is in communication with the atomization cavity.

[0060] The air inlet channel is in communication with the atomization cavity through the shell of the atomization main body, forming a complete air flow path, when the atomizer works, external air enters the atomization cavity through the air inlet channel, mixes with the heated atomized liquid and generates smoke, and then flows through the smoke channel and flows out of the smoke outlet together with the smoke.

[0061] The atomization assembly and the atomizer provided in the application drive the piston assembly to move under the action of external force, i.e. push the guide part to move along the guide hole, and the guide part is always blocked at the guide hole and guided by the guide hole during the process, i.e. the piston assembly can be pushed without contacting the atomized liquid. Through the separable design of the liquid outlet hole and the blocking part, and the guiding cooperation of the guide part and the guide hole, the liquid outlet hole can be opened or closed without contacting the atomized liquid when the atomization assembly is used, the leakage of the atomized liquid that may occur when the liquid outlet is controlled is prevented, and the user experience is ensured.

It is to be understood that the use of the terms so-termed "example", "for example" or the like in the present application is intended to indicate that an example, an illustration or a description is used to convey the relevant concept. Any embodiment or design solution described as "example" or "for example" in the present application should not be interpreted as preferable or superior to other embodiments or design solutions. Rather, the use of the terms "example" or "for example" is intended to present the relevant concept in a specific way.

[0080] An atomizer is an electronic product that imitates a cigarette, having a similar appearance, smoke, taste and feeling to a cigarette. The atomizer is mainly composed of four parts, namely, an aerosol substrate (containing nicotine, flavoring, solvent propylene glycol, etc.), a heating system, a power supply and a filter. By heating and atomizing, the atomizer can generate aerosol with a specific odor for users to use, and nicotine in the atomized liquid is the main component of the atomizer.

[0081] Specifically, in the prior art, the atomizer includes an atomizing assembly and an atomizing main body, and the atomizing assembly stores an aerosol substrate such as an atomized liquid. When the atomizing assembly and the atomizing main body are connected, the battery in the atomizing main body is electrically connected to the atomizing assembly in the atomizing assembly, the atomizing assembly heats the aerosol substrate in the atomizing assembly and releases it as an aerosol.

[0082] In the prior art, one atomizing main body is usually adapted with multiple atomizing assemblies so as to be replaced for use after the aerosol substrate in the atomizing assembly is consumed. In order to ensure the atomization effect of the aerosol substrate, the atomizing assembly usually adopts an atomizing assembly with a pore structure.

[0083] Some models of atomizing assemblies on the market include a first shell, a third shell, a first shell top seal, a spring, a piston, an upper support and an upper support seal and a liquid guide. The first shell is provided with an oil storage compartment for storing an aerosol substrate; the piston is arranged in the oil storage compartment, and a compression spring is arranged between the piston and the first shell to drive the piston to move up and down. The upper part of the piston is provided with a liquid outlet hole, and the aerosol substrate can flow into the upper part of the upper support along the liquid outlet hole of the piston. The upper support is provided with a slope guide structure, and the piston has a tendency to seal the liquid outlet hole along the slope guide structure under the action of the spring. In this application, the first shell and the upper support realize the sealing of the aerosol substrate through the upper support seal, the guide structure is arranged on the upper support, and the piston has a tendency to seal the liquid outlet hole along the guide structure under the action of the spring, so that the piston extends into the liquid outlet hole of the upper support under the action of the spring to seal the oil storage compartment.

[0084] However, there is a risk of liquid leakage in this design. Specifically, when the atomization assembly and the atomization main body are assembled into one, the push rod of the atomization main body extends into the liquid outlet hole and pushes the sealing plug to move in the first direction, thereby releasing the aerosol substrate. Among them, the atomization assembly and the atomization main body are two independent assemblies, the push rod belongs to the atomization main body assembly, and the rest belongs to the atomization assembly. The liquid absorbing member is generally a porous oil absorbing cotton, which is a die-cut part with a large processing size tolerance of ±0.2 mm. In addition, since the push rod belongs to the atomization main body assembly and the liquid absorbing member belongs to the atomization assembly, when the atomization assembly is inserted into the atomization main body, in order to avoid the push rod scratching the liquid absorbing member when the atomization assembly is inserted into the atomization main body, a large assembly gap needs to be left between the push rod and the liquid absorbing member. It is recommended that this gap be greater than 0.5 mm. Due to the existence of this gap, the aerosol substrate is easy to flow down along the push rod to the atomization chamber or other positions, causing liquid leakage, and even being sucked into the user's mouth, affecting the user's experience.

[0085] In addition, in this design, the sealing member will move up and down in one direction under the action of the spring. However, the sealing member is easy to deviate from the preset position when moving, and it is possible that the sealing member cannot return to the preset position when resetting, thereby causing the aerosol substrate to be unable to be sealed and leaking.

[0086] Therefore, the present application provides an atomization assembly and an atomizer. During the movement of the piston assembly, the blocking part opens the liquid outlet hole under the pushing force of the push rod, so that the atomized liquid flows out and is directly absorbed by the liquid absorbing member. Specifically, during this process, the push rod pushes the guide part to move along the guide hole, and the guide part is always blocked at the guide hole and guided by the guide hole, that is, the push rod can realize the pushing action of the piston assembly without contacting the atomized liquid. Through the separable design of the liquid outlet hole and the blocking part, and the guiding cooperation of the guide part and the guide hole, the push rod can open or close the liquid outlet hole without contacting the atomized liquid, preventing the atomized liquid from leaking along the push rod of the atomization main body into the atomization chamber of the atomization main body when controlling the oil, and ensuring the user's experience.

[0087] The following will be described in detail Figures 1-7 The atomization assembly provided by the embodiment of the present application is described in detail.

[0088] The present embodiment provides an atomization assembly, which is used in cooperation with an atomization main body. Among them, the atomization assembly is usually referred to as the mouthpiece of the atomizer, which is a necessary component mounted on the atomizer. In addition, according to the different nicotine content, the atomization assembly can be divided into four types of high, medium, low and zero, which can be selected according to the user's use demand.

[0089] Specifically, the following will be described in detail Figure 1 , Figure 2 and Figure 3The atomization assembly comprises an inner shell 200 and a piston assembly 300. The inner shell 200 has a liquid storage cavity 210 for storing atomization liquid, i.e. aerosol substrate. Optionally, the atomization liquid can be oil liquid, such as tobacco tar. The inner shell 200 is provided with spaced guide holes 220 and liquid outlet holes 230 on one side in the axial direction of the atomization assembly, wherein the guide holes 220 are used to cooperate with the guide portion 310 of the piston assembly 300 to ensure the movement of the piston assembly 300, and the liquid outlet holes 230 are used to release the atomization liquid when the piston assembly 300 moves.

[0090] The piston assembly 300 is movably arranged in the liquid storage cavity 210 and is provided with a guide portion 310 and a blocking portion 320. The guide portion 310 is in guiding cooperation with the guide holes 220, and specifically, the atomization body 10 is arranged on the side of the guide portion 310 away from the liquid storage cavity 210. The atomization body 10 acts on the guide portion 310 to drive the piston assembly 300 to move. The blocking portion 320 is used to open or close the liquid outlet holes 230 to control the release of the atomization liquid. The piston assembly 300 is configured to move under the driving of the atomization body 10 when the atomization body 10 is connected to the atomization assembly.

[0091] Specifically, when a user uses the atomization assembly, the atomization body 10 is connected to the atomization assembly, and the push rod 11 of the atomization body 10 will contact the piston assembly 300. Under the driving of the atomization body 10, the piston assembly 300 moves. Subsequently, the blocking portion 320 moves away from the liquid outlet holes 230, allowing the atomization liquid to flow out of the liquid storage cavity 210 through the liquid outlet holes 230 and temporarily store in the liquid suction member. The user sucks the smoke outlet 120, and the atomization body 10 controls the atomizer to atomize the atomization liquid into gas to form smoke similar to real smoke, which flows out of the smoke outlet 120 through the smoke channel 130.

[0092] During the movement of the piston assembly 300, the blocking portion opens the liquid outlet holes 230 under the pushing force of the push rod 11 to allow the atomization liquid to flow out and be directly absorbed by the atomizer. Specifically, during this process, the push rod 11 pushes the guide portion 310 to move along the guide holes 220. The guide portion 310 is always blocked at the guide holes 220 and cooperates with the guide holes 220, i.e. the push rod 11 can push the piston assembly 300 without contacting the atomization liquid. Through the separable design of the liquid outlet holes 230 and the blocking portion 320 and the guiding cooperation of the guide portion 310 and the guide holes 220, the push rod 11 can open or close the liquid outlet holes 230 without contacting the atomization liquid, preventing the atomization liquid from leaking along the push rod 11 of the atomization body 10 into the atomization cavity of the atomization body 10 to cause liquid leakage, and ensuring the user's experience.

[0093] Optionally, in combination with Figure 1 , Figure 4 and Figure 5The height of the guide portion 310 is higher than the height of the blocking portion 320 in the axial direction. Specifically, the height of the guide portion 310 is higher than the height of the blocking portion 320 in the direction of the piston support 330 towards the bottom cover 200b. When the blocking portion 320 opens or closes the liquid outlet hole 230, the guide portion 310 is always located in the guide hole 220.

[0094] Optionally, in combination with Figure 1 , Figure 4 and Figure 5 , the liquid outlet hole 230 is designed as an open hole towards the blocking portion 320. Correspondingly, the cross section of the end of the blocking portion 320 towards the liquid outlet hole 230 gradually decreases, and the liquid outlet hole 230 is matched with the blocking portion 320. This design makes the blocking portion 320 more smoothly block into the liquid outlet hole 230 when the blocking portion 320 moves towards the liquid outlet hole 230. In addition, the open design of the liquid outlet hole 230 also provides a flow direction for the atomized liquid, improving the smoothness of the atomized liquid flow.

[0095] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 3 , the atomization assembly further comprises a shell 100 having a containing cavity 110 and a smoke outlet 120 communicating with the containing cavity 110, for protecting the internal structure and providing a smoke outlet.

[0096] The inner shell 200 is arranged in the containing cavity 110, and part of the outer wall of the inner shell 200 is spaced from the inner wall of the shell 100 to jointly define a flue 130 communicating with the smoke outlet 120. Optionally, the flue 130 can be one or multiple. After the atomized liquid flows out and is directly absorbed by the liquid suction member, the atomizer is controlled by the atomization main body to atomize the atomized liquid into gas, which then flows out through the flue 130 defined by the inner shell 200 and the shell 100, realizing the use of the atomizer.

[0097] In some embodiments, in combination with Figure 1 and Figure 3 , the piston assembly 300 comprises a piston support 330 movable in the axial direction of the atomizer. When the atomization main body 10 is connected with the atomization assembly and needs to use the atomization assembly, the push rod 11 of the atomization main body 10 pushes the piston support 330 to move in the axial direction of the atomizer. The guide portion 310 and the blocking portion 320 are both arranged in the piston support 330. The guide portion 310 is tightly matched with the guide hole 220 on the inner shell 200 to ensure that the piston support 330 does not deviate from the track when moving. In addition, the guide portion 310 also plays a role in isolating the atomized liquid in the liquid storage cavity 210 from the push rod 11. In addition, the blocking portion 320 is used to open or close the liquid outlet hole 230. When the piston support 330 moves, i.e. the push rod 11 moves the guide portion 310 moves, the blocking portion 320 will move accordingly, thereby controlling the flow of the atomized liquid.

[0098] The introduction of the piston support 330 makes the piston assembly 300 more stable during movement, reducing the risk of leakage caused by deviation or shaking. In addition, the close fit of the guide portion 310 with the guide hole 220 and the precise control of the plugging portion 320 on the liquid outlet hole 230 make the outflow of the atomized liquid more uniform and controllable.

[0099] Optionally, a sealing member can also be provided on the guide portion 310 to enhance the sealing of the connection between the guide portion 310 and the guide hole 220.

[0100] In some embodiments, in combination with Figure 1 and Figure 3 , the piston support 330 divides the liquid storage cavity 210 into a first chamber 210a and a second chamber 210b. The first chamber 210a is located on the side of the piston support 330 facing the smoke outlet 120, and the second chamber 210b is located on the side of the piston support 330 facing the liquid outlet hole 230. The separation design of the first chamber 210a and the second chamber 210b makes the distribution of the atomized liquid in the liquid storage cavity 210 more uniform, and also helps to reduce the turbulence and air bubbles of the atomized liquid during movement, thereby improving the atomization effect. The piston support 330 is provided with a communication hole 331 that communicates the first chamber 210a and the second chamber 210b. The guide portion 310 and the plugging portion 320 are located on the side of the piston support 330 facing the second chamber 210b. The communication hole 331 allows the atomized liquid to flow from the second chamber 210b into the first chamber 210a when the piston support 330 moves, and then be absorbed by the atomizer through the liquid outlet hole 230. When the piston support 330 moves, the guide portion 310 moves along the guide hole 220 on the inner shell 200, while the plugging portion 320 opens or closes the liquid outlet hole 230, thereby controlling the flow of the atomized liquid.

[0101] Optionally, the size of the communication hole 331 can be designed according to actual needs to ensure smooth flow of the atomized liquid, and also to avoid excessive atomized liquid flowing into the atomizer at one time, which may cause insufficient atomization or leakage.

[0102] By dividing the liquid storage cavity 210 into two chambers and providing a communication hole 331 to control the flow of the atomized liquid, the control of the amount of atomized liquid flowing out each time it is used is achieved, which helps to reduce the waste and leakage of the atomized liquid. In addition, the distribution and flow path of the atomized liquid in the liquid storage cavity 210 are optimized, which helps to improve the atomization effect and enhance the user's experience.

[0103] Optionally, the communication hole 331 and the liquid outlet hole 230 are separately provided on the two sides of the guide portion 310. In this way, when the piston assembly 300 moves, the atomized liquid flows from the communication hole 331 to the liquid outlet hole 230 through the guide portion 310, ensuring the smoothness of the flow of the atomized liquid.

[0104] In some embodiments, in combination with Figure 4 , Figure 5 and Figure 7 , the side wall 201 of the inner shell 200 is provided with a sliding rail 240 extending along the axial direction of the atomizer, which provides a stable guide path so that the piston support 330 can maintain a linear motion during movement, reducing the possibility of deviation or shaking. The side wall of the piston support 330 is provided with a sliding protrusion 332 which is in sliding fit with the sliding rail 240. The sliding protrusion 332 ensures that the piston support 330 always moves along the track of the sliding rail 240 during movement, thereby improving the accuracy and stability of movement.

[0105] In this way, by providing the sliding rail 240 on the side wall 201 of the inner shell 200 and the sliding protrusion 332 on the side wall of the piston support 330, a stable sliding fit between the piston support 330 and the inner shell 200 is achieved, improving the accuracy and stability of movement of the piston assembly 300, and also helping to reduce the risk of wear and leakage.

[0106] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 3 , the piston assembly 300 further comprises an elastic return member 340 which is arranged between the piston support 330 and the inner shell 200. When the piston support 330 is pushed to move, the elastic return member 340 will exert its elastic action to push the piston support 330 to automatically return to the preset position. In this way, the elastic return member 340 realizes the reset function of the piston assembly 300, ensuring that the piston assembly 300 can return to the preset position after each use, ensuring the normal operation and continuous use of the atomizer.

[0107] Optionally, the material of the elastic return member 340 can be stainless steel, silicone rubber, etc.

[0108] By introducing the elastic return member 340, the automatic reset function of the piston support 330 after movement is realized, ensuring that the piston assembly 300 can return to the preset position after each use, improving the degree of automation of the atomizer.

[0109] In addition, the introduction of the elastic return member 340 also enhances the stability of the piston assembly 300. During use of the atomizer, if accidental vibration or impact occurs, the elastic return member 340 can also help the piston support 330 to maintain its position, reducing the possibility of deviation or shaking.

[0110] In some embodiments, in combination with Figure 1 and Figure 3The side wall 201 on the side opposite to the guide hole 220 of the inner shell 200 is provided with a first fixing groove 250, the piston support 330 is provided with a second fixing groove 333 opposite to the first fixing groove 250, one end of the elastic reset member 340 is fixed in the first fixing groove 250, and the other end is fixed in the second fixing groove 333.

[0111] The fixing mode ensures the position stability of the elastic reset member 340, so that the elastic reset member 340 cannot be loosened or fallen off in a long-term use process, and the stable reset of the piston support 330 is ensured. In addition, since the elastic reset member 340 is firmly fixed in the two groove positions, the elastic reset member 340 can provide stable reaction force when the piston support 330 moves, and it is ensured that the piston support 330 can accurately return to the preset position.

[0112] Optionally, the first fixing groove 250 and the second fixing groove 333 can be adaptively designed according to the end shape of the elastic reset member 340, to ensure the installation stability of the elastic reset member 340. For example, the first fixing groove 250 and the second fixing groove 333 can be designed as a circular groove

[0113] By fixing one end of the elastic reset member 340 in the first fixing groove 250 of the inner shell 200 and the other end in the second fixing groove 333 of the piston support 330, the stable installation of the elastic reset member 340 is realized, the accurate reset of the piston support 330 after movement is ensured, and the stability and reliability of the entire piston assembly 300 are improved.

[0114] Optionally, in combination with Figure 4 and Figure 5 , the piston support 330 is provided with a limiting cylinder 370, and the second fixing groove 333 is arranged in the fixing cylinder.

[0115] In some embodiments, in combination with Figure 1 and Figure 3 , the piston assembly 300 further comprises a first sealing plug 350 and a second sealing plug 360.

[0116] The first sealing plug 350 is fixedly arranged on the piston support 330, the first sealing plug 350 is adapted to the guide hole 220, and the first sealing plug 350 constitutes the guide part 310. Specifically, when the piston support 330 moves, the push rod 11 on the atomization main body 10 pushes the first sealing plug 350 to move, the first sealing plug 350 slides along the inner wall of the guide hole 220, and the movement path of the piston support 330 is ensured to be stable. In addition, the close fit between the first sealing plug 350 and the guide hole 220 can prevent the atomization liquid or gas from leaking out of the guide hole 220, realize that the push rod 11 moves the piston support 330 without contacting the atomization liquid, and ensure the sealing of the atomization assembly and prevent liquid leakage.

[0117] In addition, the second sealing plug 360 is fixedly arranged on the piston support 330, the second sealing plug 360 is matched with the liquid outlet hole 230, and the second sealing plug 360 constitutes the blocking part 320. The second sealing plug 360 plays a role of blocking and liquid outlet control. When the piston support 330 is not moved, the second sealing plug 360 blocks the liquid outlet hole 230 to prevent the atomized liquid from leaking; when the piston support 330 is moved, the second sealing plug 360 moves to open or close the liquid outlet hole 230, thereby controlling the outflow amount of the atomized liquid.

[0118] For example, the materials of the first sealing plug 350 and the second sealing plug 360 can be rubber, silicone, polytetrafluoroethylene (PTFE) or the like.

[0119] By arranging the first sealing plug 350 and the second sealing plug 360, the sealing performance and the oil outlet stability of the piston assembly 300 are improved, which helps to prevent the atomized liquid or gas from leaking, thereby ensuring the normal operation of the atomization assembly and the use safety of the user.

[0120] In some embodiments, in combination with Figure 4 and Figure 5 , the guide part 310 and the blocking part 320 are integrally formed, that is, the first sealing plug 350 and the second sealing plug 360 are integrally formed. The first sealing plug 350 and the second sealing plug 360 integrally formed are more compact in structure, improve the structural stability of the atomization assembly, and also simplify the manufacturing process. In addition, the first sealing plug 350 and the second sealing plug 360 integrally formed are more uniform in material and structure, which can provide better sealing effect, thereby ensuring the normal operation of the atomization assembly and the use safety of the user.

[0121] Optionally, the first sealing plug 350 and the second sealing plug 360 can also be integrally formed with the piston support 330. Correspondingly, the material of the piston support 330 can also be rubber, silicone, polytetrafluoroethylene (PTFE) or the like.

[0122] In some embodiments, in combination with Figure 1 and Figure 3 , the inner shell 200 includes a shell body 200a and a bottom cover 200b.

[0123] The shell body 200a defines the liquid storage cavity 210, and the shell body 200a is provided with an opening on the side away from the smoke outlet 120 along the axial direction of the atomizer. In addition, the shape and size of the shell body 200a can be designed according to the overall design of the atomization assembly and the storage requirement of the atomized liquid. The bottom cover 200b covers the opening, and the guide hole 220 and the liquid outlet hole 230 both penetrate the bottom cover 200b.

[0124] The opening of the shell main body 200a is sealed by the bottom cover 200b, ensuring the sealing of the liquid storage cavity 210 and preventing leakage of the atomized liquid. In addition, the separate design of the shell main body 200a and the bottom cover 200b makes the assembly process simpler and more convenient, and facilitates subsequent maintenance and replacement.

[0125] In some embodiments, in combination with Figure 6 and Figure 7 , the bottom cover 200b is provided with a limiting protrusion 203, and the shell main body 200a is provided with a bayonet 204 for clamping the limiting protrusion 203, and the limiting protrusion 203 and the bayonet 204 jointly realize the clamping and fitting between the bottom cover 200b and the shell main body 200a.

[0126] In some embodiments, in combination with Figure 1 , the inner shell 200 further comprises a first sealing member 260, which is arranged on the peripheral side of the bottom cover 200b to seal the gap between the bottom cover 200b and the shell main body 200a. Optionally, the first sealing member 260 can be installed on the peripheral side of the bottom cover 200b by pressing, pasting or embedding, etc., to ensure that the first sealing member 260 can be positioned on the gap between the bottom cover 200b and the shell main body 200a, avoiding damage or deformation due to improper installation.

[0127] For example, the material of the first sealing member 260 can be rubber, silicone or polytetrafluoroethylene (PTFE), etc.

[0128] The first sealing member 260 can seal the gap between the bottom cover 200b and the shell main body 200a, preventing leakage of the atomized liquid and improving the overall sealing performance of the atomization assembly.

[0129] In some embodiments, in combination with Figure 1 and Figure 6 , the edge of the bottom cover 200b is further provided with an air pressure balance hole 270 penetrating along the axial direction of the atomizer, and the liquid storage cavity 210 has a liquid outlet state and a closed state, wherein in the liquid outlet state, the first sealing member 260 opens the air pressure balance hole 270, and in the closed state, the first sealing member 260 closes the air pressure balance hole 270.

[0130] During the use of the atomization assembly, the air pressure inside the liquid storage cavity 210 will change with the consumption and atomization of the atomized liquid, and the air pressure balance hole 270 can allow air to enter and exit the liquid storage cavity 210 to adjust the air pressure inside the liquid storage cavity 210 to keep it balanced with the external air pressure.

[0131] Specifically, in the liquid outlet state, the first sealing member 260 opens the air pressure balance hole 270 to allow air to enter the liquid storage cavity 210 to maintain the balance of the air pressure; in the closed state, the first sealing member 260 closes the air pressure balance hole 270 to prevent the atomized liquid or air from leaking out of the air pressure balance hole 270.

[0132] The cooperation of the air pressure balance hole 270 and the first sealing member 260 balances the air pressure inside the liquid storage cavity 210 with the air pressure outside, avoiding leakage of the atomized liquid or poor atomization effect due to air pressure changes. In addition, the first sealing member 260 can close the air pressure balance hole 270 in a closed state, preventing leakage of the atomized liquid or air, and improving the sealing performance of the atomization assembly.

[0133] In some embodiments, in combination with Figure 1 and Figure 2 , the inner shell 200 includes a side wall 201 and a top wall 202, the top wall 202 is opposite to the smoke outlet 120, a part of the flue 130 is located between the side wall 201 and the inner wall of the outer shell 100, and another part is located between the top wall 202 and the inner wall of the outer shell 100. In this way, the flue 130 can guide the atomized atomized liquid from the liquid storage cavity 210 to the smoke outlet 120.

[0134] The smoke outlet 120 is provided with a flow guide part 140 extending towards the top wall 202, the flow guide part 140 abuts against the top wall 202, and the flow guide part 140 separates the flue 130 from the space around the smoke outlet 120, preventing the smoke from spreading around the smoke outlet 120, thereby ensuring that the smoke can be concentrated and orderly outflow.

[0135] Through the guidance of the flow guide part 140, the concentration and orderliness of the smoke flowing out of the smoke outlet 120 are ensured, the atomization effect and taste of the atomizer are improved, and in addition, the spread and leakage of the smoke around the smoke outlet 120 are prevented, and the sealing performance of the atomizer is improved.

[0136] In some embodiments, in combination with Figure 1 and Figure 3 , the atomization assembly further includes a second sealing member 400, which is arranged between the top wall 202 and the flow guide part 140 to provide an additional sealing layer for the atomization assembly to prevent the smoke from leaking out of the gap between the top wall 202 and the flow guide part 140.

[0137] In this way, the second sealing member 400 further enhances the sealing between the top wall 202 and the flow guide part 140, ensuring that the smoke can be more concentrated and orderly through the smoke outlet 120, improving the atomization effect and taste of the atomizer.

[0138] For example, the material of the second sealing member 400 can be selected from rubber, silicone, or polytetrafluoroethylene (PTFE), etc.

[0139] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 3The atomization assembly further comprises a liquid suction member 500 arranged at one end of the liquid outlet hole 230 away from the liquid storage cavity 210, for absorbing and storing the atomized liquid flowing out of the liquid storage cavity 210 through the liquid outlet hole 230, so as to continuously supply the atomized liquid during the atomization process. For example, the liquid suction member 500 can be made of porous materials such as ceramics, fibers or special polymers.

[0140] The liquid suction member 500 is provided with an avoiding hole 510 for avoiding the guide part 310, and the guide part 310 passes through the avoiding hole 510 to cooperate with the atomization main body 10. The avoiding hole 510 is designed to enable the guide part 310 to smoothly pass through the liquid suction member 500 and form a stable connection with the atomization main body 10, thereby improving the connection reliability and stability between the atomization assembly and the atomization main body 10.

[0141] By introducing the liquid suction member 500 and designing the avoiding hole 510 to cooperate with the connection between the guide part 310 and the atomization main body 10, the stability of the atomization assembly in supplying atomized liquid is improved, and the reliability of the atomization assembly in use is improved, thereby ensuring the user experience.

[0142] In some embodiments, in combination with Figure 1 and Figure 3 The shell 100 further cooperates with the inner shell 200 to define an atomization cavity 600 located at one side of the inner shell 200 away from the smoke outlet 120. In this way, the atomization cavity 600 is defined by the shell 100 and the inner shell 200, which is conducive to controlling the temperature and pressure during the atomization process, thereby improving the efficiency and stability of the atomization. The liquid suction member 500 is located in the atomization cavity 600 and is responsible for absorbing the atomized liquid from the liquid storage cavity 210 and supplying it to the atomizer for atomization. The design of the liquid suction member 500 in the atomization cavity 600 enables the atomized liquid to be smoothly transmitted from the liquid storage cavity 210 to the atomizer, and also avoids leakage of the atomized liquid during the atomization process.

[0143] In the connected state of the atomization main body 10 and the atomization assembly, the atomization main body 10 blocks the atomization cavity 600, which helps to prevent smoke from accumulating in the atomization cavity 600 and ensures that the smoke can flow out of the smoke outlet 120 smoothly. Specifically, the atomization main body 10 is provided with an air inlet channel 12, which communicates the atomization cavity 600 and the flue 130 when the atomization main body 10 is connected to the atomization assembly.

[0144] When the atomization main body 10 is connected to the atomization assembly and the atomizer is started, the atomization main body 10 is supplied with air through the air inlet channel 12, the air flows through the atomization cavity 600, the atomizer works, the atomized liquid in the liquid suction member 500 is atomized into smoke, and the smoke temporarily accumulates in the atomization cavity 600 and flows out of the smoke outlet 120 together with the smoke through the flue 130.

[0145] The design of the atomization cavity 600 enables the atomization process to be carried out in a relatively closed space, which is conducive to controlling the temperature and pressure during the atomization process, thereby improving the efficiency and stability of atomization. In addition, the design of the atomization body 10 blocking the atomization cavity 600 enables the smoke to flow smoothly out of the smoke outlet 120, avoiding the accumulation and leakage of smoke in the atomization cavity 600, and improving the user's experience.

[0146] The following will be described in detail Figures 1-3 The atomizer provided by another aspect of the present application is described in detail.

[0147] The present embodiment provides an atomizer, which can be divided into nicotine atomizers, non-nicotine atomizers, disposable cigarettes, disposable atomization component atomizers, oil-filled atomizers, etc. according to the composition of the atomized liquid and the use method. The present embodiment takes the disposable atomization component atomizer as an example, i.e. the atomization component and the atomization body 10 are designed to be detachable, the atomization body 10 has a battery 13 that can be charged and reused, and the atomization component can be replaced after use.

[0148] In combination with Figure 1 , Figure 2 and Figure 3 , the atomizer comprises the atomization body 10 and the atomization component in any of the above embodiments.

[0149] Among them, the atomization body 10 and the atomization component are detachably connected, so that the user can replace the atomization component or clean the atomization body 10. Exemplarily, the connection between the atomization component and the atomization body 10 can be selected from threaded connection, magnetic attraction connection or other connection modes.

[0150] The atomization body 10 is used to atomize the atomized liquid absorbed by the liquid absorbing member 500 and discharge it to the smoke outlet 120 through the flue 130. The atomization body 10 is also used to drive the piston assembly 300 to move to open the liquid outlet hole 230.

[0151] Exemplarily, the liquid absorbing member 500 is provided with a heating member, such as a heating wire. When the atomization body 10 is connected with the atomization component and the atomizer is started, the piston assembly 300 will be driven to move by the driving force, thereby opening the liquid outlet hole 230 and allowing the atomized liquid to flow into the liquid absorbing member 500. The atomization body 10 supplies power to the heating wire, and the liquid absorbing member 500 heats and atomizes the atomized liquid. Exemplarily, the liquid absorbing member 500 can also use heating wire, ultrasonic wave or other atomization technology to realize the atomization of the atomized liquid.

[0152] Through the design of the piston assembly 300, the supply amount of the atomized liquid can be controlled, the efficiency and stability of atomization are improved, in addition, the stability and reliability of the atomizer during use are also improved, the risk of liquid leakage is reduced, and the user's experience is improved.

[0153] In addition, in some other embodiments, the heating element can also be arranged in the atomization body and selectively electrically connected with the atomization body 10. Specifically, when using the atomizer, first, the piston assembly 300 is driven to move by the driving force, thereby opening the liquid outlet hole 230 to allow the atomization liquid to flow into the liquid suction element 500, and then the atomization body 10 is electrically connected with the liquid suction element 500, and the liquid suction element 500 is heated and atomizes the atomization liquid by supplying power to the heating element.

[0154] In this design, by arranging the heating element in the atomization body, the atomization body can be adapted to multiple atomization assemblies, saving the manufacturing cost of the atomization assembly, and in addition, the replacement of the atomization assembly avoids the discarding of the heating element, ensuring the reuse of the heating element.

[0155] In some embodiments, in combination with Figure 3 The atomization body 10 includes a push rod 11 for driving the piston assembly 300 to move. The movement of the push rod 11 drives the piston assembly 300 to open or close the liquid outlet hole 230, thereby controlling the flow of atomization liquid from the atomization assembly into the liquid suction element 500 and being atomized by the atomizer.

[0156] For example, the push rod 11 can be used to receive a driving force from the inside of the atomization body 10 (such as a force generated by a motor, an electromagnet, etc.), and transmit this driving force to the piston assembly 300 to drive the piston assembly 300 to move.

[0157] For example, the material of the push rod 11 can be selected from high-strength and high-wear-resistant metal materials such as stainless steel and alloy steel.

[0158] By introducing the push rod 11 as a component for driving the piston assembly 300 to move, the atomization efficiency of the atomizer and the reliability of the use of the atomization body 10 are improved.

[0159] In some embodiments, in combination with Figure 3 The atomization body 10 includes an air inlet channel 12 that is in communication with the atomization cavity 600. The air inlet channel 12 is usually designed on the shell 100 of the atomization body 10 to form one or more openings in communication with the atomization cavity 600. For example, the opening can be designed in a circular, oval, rectangular or other shape, depending on the overall design of the atomizer and user needs.

[0160] The air inlet channel 12 is in communication with the atomization cavity 600 through the shell 100 of the atomization body 10 to form a complete air flow path. When the atomizer is working, external air enters the atomization cavity 600 through the air inlet channel 12, mixes with the heated atomization liquid and generates smoke, and then flows through the smoke channel 130 and is discharged from the smoke outlet 120 together with the smoke.

[0161] Exemplarily, the air inlet channel 12 can be designed with an air flow regulating valve, which controls the concentration and taste of the smoke by adjusting the air flow, thereby improving the user experience.

[0162] In some embodiments, in combination with Figure 3 The atomization body 10 further comprises a battery 13 for supplying power to the atomization body 10.
