Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and in particular to a liquid supply component, a host and an electronic atomization device. Background Art

[0002] An electronic atomization device includes an atomizer and a main unit. The atomizer can atomize the liquid to be atomized to produce an aerosol; the main unit can not only power the atomizer but also supply the liquid to be atomized to the atomizer.

[0003] Typically, the main unit includes a liquid supply assembly and a detachable liquid storage bottle. The liquid storage bottle stores the liquid to be atomized; when the atomizer needs liquid, the power component in the liquid supply assembly can extract the liquid to be atomized from the liquid storage bottle and supply it to the atomizer through the liquid injection tube.

[0004] However, after the liquid supply assembly is filled, the remaining liquid in the liquid filling tube will flow back into the liquid storage bottle, contaminating the liquid in the liquid storage bottle and causing the quality of the aerosol atomized by the electronic atomization device to deteriorate. Summary of the Invention

[0005] The present application mainly provides a liquid supply component, a host and an electronic atomization device. The liquid supply component can solve the problem of liquid backflow in the injection tube contaminating the liquid in the liquid storage bottle.

[0006] To solve the above technical problems, the present application adopts a technical solution: providing a liquid supply assembly, which includes a power component, a liquid injection tube, a one-way valve, and a liquid storage component. The power component is used for liquid injection; the liquid injection tube is connected to the power component; the one-way valve is connected to the liquid path between the liquid injection tube and the one-way valve, and is used to open or close the liquid path between the liquid storage bottle and the liquid injection tube; the liquid storage component is in fluid communication with the liquid injection tube, and is used to store liquid that flows back through the liquid injection tube;

[0007] After the power component is injected with liquid, the one-way valve is closed and the liquid in the injection pipe flows back to the liquid storage component.

[0008] Among them, the liquid supply component also includes a connecting piece, which has a connecting cavity; the liquid storage piece is connected to the connecting cavity; the injection pipe is connected to the connecting cavity; a one-way valve is arranged on the connecting piece, and the one-way valve is used to open or close the liquid inlet connected to the connecting cavity.

[0009] The liquid storage component is located on the top side of the connecting component, and the one-way valve is located on the bottom side of the connecting component.

[0010] The liquid storage element expands when filled with liquid and contracts when discharged.

[0011] Among them, the liquid storage part is a folding bellows, which includes a plurality of folding parts connected in sequence and arranged in a stacked manner. The folding parts are connected to the connecting cavity and are used to store liquid; the folding parts expand and unfold when filled with liquid, and fold and shrink when discharged.

[0012] Wherein, the one-way valve is an electronic one-way valve; or

[0013] When the pressure on the side of the one-way valve facing the liquid injection pipe is greater than or equal to the pressure on the side away from the liquid injection pipe, the one-way valve is closed; when the pressure on the side of the one-way valve facing the liquid injection pipe is less than the pressure on the side away from the liquid injection pipe, the one-way valve is opened.

[0014] The one-way valve is provided with a liquid hole and a plurality of sealing parts arranged around the liquid hole, and the plurality of sealing parts cooperate to seal the liquid hole;

[0015] When the pressure exerted on the side of the multiple sealing parts toward the liquid injection tube is greater than or equal to the pressure exerted on the side away from the liquid injection tube, the multiple sealing parts cooperate to close the liquid hole; when the pressure exerted on the side of the multiple sealing parts toward the liquid injection tube is less than the pressure exerted on the side away from the liquid injection tube, the multiple sealing parts open toward the side of the liquid injection tube to open the liquid hole.

[0016] The sealing portion is arranged in an arched shape, with the arched convex surface of the sealing portion facing the liquid injection tube and the arched concave surface of the sealing portion facing away from the liquid injection tube.

[0017] Wherein, a clamping groove is provided on a side of the connecting piece away from the liquid injection pipe and surrounding the liquid inlet of the connecting piece, and the one-way valve is assembled in the clamping groove.

[0018] Among them, the power component is also used to drive the liquid in the injection tube to flow back to the liquid storage component after the injection is completed.

[0019] The present application also provides a host for an electronic atomization device, the host including a battery, a liquid storage bottle and the above-mentioned liquid supply assembly, and the host is used to power and supply liquid to the atomizer of the electronic atomization device.

[0020] The present application also provides an electronic atomization device, which includes an atomizer and the above-mentioned liquid supply assembly, and the liquid injection tube is used to inject liquid into the atomizer.

[0021] The atomizer includes a shell assembly and an air outlet pipe. The shell assembly is provided with a buffer chamber; the air outlet pipe is provided in the shell assembly and is connected to the air nozzle of the shell assembly;

[0022] The air outlet pipe has an air leakage hole, which connects the buffer cavity with the inner space of the air outlet pipe, and the liquid injection pipe is used to inject liquid into the buffer cavity.

[0023] The beneficial effects of the present application are as follows: Different from the prior art, the present application provides a liquid supply assembly and an electronic atomization device. The liquid supply assembly is provided with a power member, a liquid injection tube, a one-way valve and a liquid storage member. Among them, the power member is used for liquid injection. The liquid injection tube is connected to the power member so that the power member can drive the liquid injection tube to supply the liquid in the liquid storage bottle to the atomizer. The one-way valve is connected to the liquid injection tube, so that when the one-way valve is in a closed state, the liquid injection tube cannot supply liquid through the liquid storage bottle connected to the one-way valve; when the one-way valve is in an open state, the liquid injection tube supplies liquid from the liquid storage bottle through the one-way valve.

[0024] The liquid storage part is connected to the liquid injection tube, and the liquid storage part is used to store the liquid refluxed through the liquid injection tube. After the liquid injection of the power part is completed, the one-way valve is closed, and the liquid injection tube is not connected to the liquid storage bottle. The liquid injection tube injects the refluxed liquid into the liquid storage part. In this way, the liquid supply component effectively prevents the liquid in the liquid injection tube from flowing back into the liquid storage bottle after the liquid injection is completed, thereby ensuring the cleanliness of the liquid in the liquid storage bottle and improving the quality of the aerosol atomized by the electronic atomization device.

[0025] Furthermore, when the power unit is refilling, it can first pump out the liquid stored in the liquid reservoir, thereby supplying the liquid in the liquid reservoir to the atomizer through the liquid injection tube. Furthermore, after the liquid stored in the liquid reservoir has been consumed to a predetermined amount, the one-way valve opens, connecting the liquid storage bottle with the liquid injection tube, allowing the power unit to supply the liquid in the liquid storage bottle to the atomizer. This allows liquid that has refluxed from the liquid reservoir to be supplied to the atomizer, preventing waste of refluxed liquid. Furthermore, when the liquid in the liquid reservoir is low, liquid from the liquid storage bottle is supplied to the atomizer, allowing the filling process to continue.

[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0040] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of such phrases in various places in the specification do not necessarily refer to the same embodiment, nor do they constitute independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0042] See also Figure 1 and Figure 2 , Figure 1This is a schematic diagram of a three-dimensional structure of the electronic atomization device 10 provided in this application. Figure 2 for Figure 1 A cross-sectional view of the electronic atomization device 10 along the AA direction.

[0043] The electronic atomization device 10 can be used to atomize liquid to be atomized. The electronic atomization device 10 includes an interconnected atomizer 20 and a main unit 30. The main unit 30 is used to power the atomizer 20 and also supply liquid to the atomizer 20. The atomizer 20 and main unit 30 can be integrally provided or detachably connected, and the design can be tailored to specific needs. In this embodiment, the atomizer 20 and main unit 30 are detachably connected.

[0044] The nebulizer 20 is used to atomize a liquid to be atomized to form an aerosol. The nebulizer 20 can be used in various fields, such as medical and electronic aerosol atomization devices. In one embodiment, the nebulizer 20 can be used in an aerosol atomization device to atomize a liquid to be atomized and generate an aerosol for inhalation by a user. Of course, in other embodiments, the nebulizer 20 can also be used in a hairspray device to atomize hairspray for hair styling, or in a medical device for treating upper and lower respiratory system diseases to atomize medical drugs.

[0045] The main unit 30 includes a housing 31, a liquid supply assembly 32, a battery 33, a mounting bracket 34, a liquid storage bottle 35, and a control device (not shown). The control device may be, for example, a circuit board or a chip. The liquid supply assembly 32, battery 33, mounting bracket 34, and control device are all located within the housing 31. The liquid supply assembly 32, control device, liquid storage bottle 35, and battery 33 are all located on the mounting bracket 34 to facilitate installation and connection of the liquid supply assembly 32, battery 33, and control device.

[0046] The terms "including," "having," and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units but may optionally include steps or units not listed, or may optionally include other steps or components inherent to the process, method, product, or apparatus.

[0047] The battery 33 is used to power the atomizer 20 and the liquid supply assembly 32. The control device has a control circuit, which is electrically connected to the battery 33 and the liquid supply assembly 32 to control the battery 33 to provide power to the liquid supply assembly 32 and the atomizer 20, control the liquid supply assembly 32 to supply liquid to the atomizer 20, and control the atomizer 20 to perform atomization.

[0048] Liquid storage bottle 35 stores the liquid to be atomized. Liquid storage bottle 35 can be made of metal such as aluminum or stainless steel, or plastic. Alternatively, liquid storage bottle 35 can have a double-layer structure, including an inner flexible oil bladder and an outer hard protective shell. The liquid storage bottle 35 only needs to be able to store the liquid to be atomized and not react with it. The shape, size, and location of the oil supply bottle are not limited and can be designed as needed.

[0049] Please refer to Figure 2 and Figure 3 , Figure 3 for Figure 1 The liquid storage bottle 35 of this embodiment is detachable, so that the liquid storage bottle 35 can be refilled or replaced when the liquid storage bottle 35 is insufficient.

[0050] The liquid storage bottle 35 can be directly connected to the mounting bracket 34 by snapping, or the liquid storage bottle 35 can be connected to the mounting bracket 34 by snapping with a snap member 36. In this embodiment, a snap slot 341 is provided on the bottom surface of the mounting bracket 34 near the liquid storage bottle 35. The snap slot 341 is used to accommodate the snap member 36. The snap member 36 snaps with the liquid storage bottle 35 at one end facing the liquid storage bottle 35. The snap member 36 can slide back and forth along the snap slot 341. When the liquid storage bottle 35 needs to be removed, the snap member 36 can be driven to slide toward the side away from the liquid storage bottle 35 to separate the snap member 36 from the liquid storage bottle 35, thereby allowing the liquid storage bottle 35 to be removed from the mounting bracket 34.

[0051] Please refer to Figure 4 , Figure 4 for Figure 1 Left side view of the electronic atomization device 10. In this embodiment, the housing 31 may further include a window 311, which is used for the user to observe the remaining amount of liquid to be atomized in the liquid storage bottle 35 in the main unit 30 from the outside. The side wall of the housing 31 opposite to the liquid storage bottle 35 may be made of a transparent material, and the transparent side wall may serve as the window 311; or the side wall of the housing 31 may have an opening, which is arranged opposite to the liquid storage bottle 35, and the opening serves as the window 311. In this embodiment, the opening is arranged opposite to the bottom of the liquid storage bottle 35, so that the user can observe the bottom of the liquid storage bottle 35 in the main unit 30 from the outside.

[0052] See also Figure 2 The liquid supply assembly 32 is used to pump the liquid to be atomized from the liquid storage bottle 35 and supply the atomized liquid to the nebulizer 20. The nebulizer 20 atomizes the liquid to be atomized to generate an aerosol. The specific structure and function of the liquid supply assembly 32 can be referred to the specific structure and function of the liquid supply assembly 32 involved in any of the following embodiments, and the same or similar technical effects can be achieved, so it is not repeated here.

[0053] In other embodiments, the host 30 may not include the liquid supply assembly 32 and the liquid storage bottle 35, and the host 30 only provides energy to the atomizer 20 without supplying liquid. That is, the liquid supply assembly 32 and the liquid storage bottle 35 may be provided independently of the host 30.

[0054] See also Figure 5 , Figure 5 for Figure 1 The present application also provides a liquid supply assembly 32, which is not limited to the liquid supply in the above-mentioned electronic atomization device 10, but can also be used in other systems that require liquid supply. The liquid supply assembly 32 can pump liquid from a liquid storage bottle 35, a liquid storage tank or a liquid storage pool, and supply the liquid to the system that requires liquid supply. The present application uses the electronic atomization device 10 as an example for explanation.

[0055] Specifically, the liquid supply assembly 32 includes a liquid injection pipe 321 , a power component 322 , a one-way valve 323 and a liquid storage component 324 .

[0056] The power piece 322 is connected to the injection pipe 321, and the injection pipe 321 is connected to the liquid storage bottle 35. The power piece 322 can pump the liquid to be atomized stored in the liquid storage bottle 35 to the injection pipe 321 to inject liquid into the atomizer 20 through the injection pipe 321.

[0057] Furthermore, the liquid injection tube 321 may include a liquid inlet tube and a liquid outlet tube, one end of the liquid inlet tube is connected to the liquid storage bottle 35, and the other end is connected to the power piece 322; one end of the liquid outlet tube is connected to the power piece 322, and the other end is used to be inserted into the atomizer 20 to supply liquid.

[0058] The power component 322 may specifically be a peristaltic pump or a piezoelectric ceramic pump. The power component 322 is electrically connected to the control circuit of the control device so as to inject liquid into the atomizer 20 upon receiving a control signal from the control device.

[0059] Specifically, when the injection tube 321 detects that the liquid level in the buffer chamber of the atomizer 20 is lower than a first liquid level value, the controller controls the power member 322 to inject liquid into the buffer chamber through the injection tube 321, and when the injection tube 321 detects that the liquid level in the buffer chamber of the atomizer 20 reaches a second liquid level value, the controller controls the power member 322 to stop injecting liquid. The first liquid level value is lower than the second liquid level value. When the liquid level in the buffer chamber of the atomizer 20 is lower than the first liquid level value, the heating element in the atomizer 20 is at risk of dry-burning; when the liquid level in the buffer chamber of the atomizer 20 is higher than the second liquid level value, the atomizer 20 is at risk of leaking.

[0060] The terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," or "third" may explicitly or implicitly include at least one of the aforementioned features.

[0061] In this embodiment, a puff detection unit (not shown) is further provided in the atomizer 20 or the main unit 30. The puff detection element is electrically connected to the control device and is used to detect the user's puffing action. The puff detection element can be, for example, an airflow sensor, a microphone, or other detection element.

[0062] The control device can detect the user's suction state according to the user's suction action. When the control device detects that the user starts to puff through the suction detection unit, the control device controls the liquid supply component 32 to supply liquid to the buffer chamber in the nebulizer 20; wherein the control device detects that the liquid level in the buffer chamber of the nebulizer 20 is higher than the second liquid level value, and suspends the liquid supply component 32 from supplying liquid to the buffer chamber. When the control device detects that the liquid level in the buffer chamber of the nebulizer 20 is lower than the first liquid level value, the control device resumes driving the liquid supply component 32 to supply liquid to the buffer chamber. When it is detected that the user stops puffing, the control device controls the liquid supply component 32 to stop supplying liquid to the nebulizer 20 and withdraws the remaining liquid to be atomized in the nebulizer 20. In this way, when the user is not puffing, there is no liquid to be atomized in the internal buffer chamber of the nebulizer 20, thereby preventing the nebulizer 20 from leaking during carrying or transportation.

[0063] In other words, the electronic atomization device 10 is of instant liquid supply type. When the electronic atomization device 10 is in a non-working state, the cache cavity is basically empty, that is, there is no liquid therein. When the electronic atomization device 10 is in a working state, the liquid supply component 32 supplies liquid to the cache cavity in real time, and when the user stops inhaling, the liquid still existing in the cache cavity will be drawn back by the liquid supply component 32, so that the cache cavity can be basically kept empty when it is not in a working state.

[0064] The injection tube 321 can also be used to detect the liquid level in the buffer chamber of the nebulizer 20. The injection tube 321 can be integrated with a liquid level detection device or liquid level detection circuit. Therefore, while injecting liquid, it can also detect the conductivity, hydraulic pressure and other parameters of the liquid in the buffer chamber of the nebulizer 20, thereby obtaining a liquid level value and feeding it back to the control device. The control device can control the liquid supply assembly 32 to inject liquid into the nebulizer 20 or stop injecting liquid based on the fed-back liquid level signal. Optionally, the liquid level detection device or liquid level detection circuit can be integrated at the end of the injection tube 321 connected to the nebulizer 20.

[0065] The one-way valve 323 is connected to the injection tube 321. Specifically, the one-way valve 323 is provided on the fluid passage between the liquid inlet pipe of the injection tube 321 and the liquid storage bottle 35 to control the opening and closing of the passage for transporting fluid between the injection tube 321 and the liquid storage bottle 35.

[0066] The one-way valve 323 can be set on the injection tube 321, or can be set in the liquid extraction channel in the liquid storage bottle 35, or the one-way valve 323 can also be set in the connecting channel between the injection tube 321 and the liquid storage bottle 35.

[0067] When the control device detects that the user starts to puff through the suction detection unit, the power part 322 is started and the one-way valve 323 is opened to inject the liquid in the liquid storage bottle 35 into the buffer chamber of the atomizer 20 through the injection tube 321. When it is detected that the user stops puffing, the liquid supply component 32 draws back the liquid in the buffer chamber and the one-way valve 323 is closed.

[0068] The liquid storage component 324 is connected to the liquid path between the liquid injection tube 321 and the one-way valve 323. The liquid storage component 324 is used to store the liquid refluxed through the liquid injection tube 321, and the liquid stored in the liquid storage component 324 is preferentially pumped into the cache chamber of the atomizer 20 during the next liquid injection.

[0069] After the power part 322 completes the liquid injection, that is, when it detects that the atomizer 20 has stopped suctioning, the liquid supply component 32 draws back the liquid in the buffer chamber and injects the returned liquid into the liquid storage part 324 for storage, thereby preventing the liquid in the injection tube 321 from flowing back into the liquid storage bottle 35, avoiding contamination of the liquid storage bottle 35.

[0070] After the power element 322 is filled with liquid, the one-way valve 323 closes, and the liquid in the liquid filling tube 321 cannot flow into the liquid storage bottle 35 through the one-way valve 323. Instead, it flows into the liquid storage element 324 for storage. In this way, the liquid in the liquid filling tube 321 is prevented from flowing back into the liquid storage bottle 35, which helps to keep the liquid storage bottle 35 clean and improve the quality of the aerosol atomized by the electronic atomization device 10.

[0071] Among them, after the power part 322 completes the liquid injection, the power part 322 can drive the liquid in the liquid injection tube 321 to flow back to the liquid storage part 324. The method of driving the liquid in the liquid injection tube 321 to flow back by the power part 322 is convenient for control and the control is relatively precise; the liquid storage part 324 can also draw back the liquid in the liquid injection tube 321, for example, the liquid storage part 324 is a syringe; or the liquid storage part 324 and the power part 322 cooperate, so that both can provide assistance to make the liquid in the liquid injection tube 321 flow back to the liquid storage part 324.

[0072] In this embodiment, the liquid storage member 324 is used to store the liquid that flows back through the liquid injection tube 321, and the liquid storage member 324 expands when the liquid is filled and contracts when the liquid is discharged.

[0073] For example, the liquid storage part 324 can be a liquid storage airbag or a folding bellows, a piston liquid storage structure, etc., wherein the liquid storage airbag and the folding bellows can be made of elastic material, and then when the liquid flows back into the liquid storage airbag and the folding bellows, the liquid storage airbag or the folding bellows expands to store the liquid. When the injection component 32 starts to inject liquid, the liquid in the liquid storage part 324 is first extracted to be injected into the buffer cavity, and the liquid in the liquid storage part 324 contracts after flowing out; the piston liquid storage structure includes a piston cylinder and a piston part, and the piston part is slidably arranged in the piston cylinder. When injecting or discharging liquid, the piston part can be driven to slide to adjust the liquid storage volume of the piston cylinder.

[0074] Among them, the liquid storage component 324 has a temporary storage chamber 3241, which is used to store the liquid refluxed through the injection tube 321 and consume the liquid in the temporary storage chamber 3241 first during the next injection. That is, when injecting, the power component 322 first pumps out the liquid stored in the liquid storage component 324.

[0075] Specifically, the liquid storage airbag is an elastic airbag, i.e., the material of the liquid storage airbag is a material with a certain degree of elasticity. The elastic airbag and the folding bellows can achieve expansion when liquid is injected into the temporary storage chamber 3241, i.e., the capacity of the temporary storage chamber 3241 automatically increases, and contraction when liquid flows out of the temporary storage chamber 3241, i.e., the capacity of the temporary storage chamber 3241 automatically decreases, without the need for additional drive control.

[0076] In this embodiment, the liquid storage member 324 is a folding bellows. When liquid is injected into the liquid storage member 324, the folding bellows expands with liquid. When the liquid flows out of the liquid storage member 324, the folding bellows contracts by releasing liquid. The folding bellows may include a bellows body 3242 and a connecting pipe 3243, wherein the bellows body 3242 has a temporary storage chamber 3241 therein, one end of the connecting pipe 3243 is connected to the temporary storage chamber 3241, and the other end is connected to the liquid path between the injection pipe 321 and the one-way valve 323. The provision of the connecting pipe 3243 facilitates the installation of the bellows body 3242 and also facilitates the fluid communication between the temporary storage chamber 3241 and the injection pipe 321. The material of the folding bellows may be an organic polymer. The shape and volume of the folding bellows are not limited and can be designed as needed.

[0077] Furthermore, the bellows body 3242 includes a plurality of folding parts connected in sequence and arranged in a stacked manner. The cavity spaces within the plurality of folding parts are interconnected to form a temporary storage cavity 3241. The folding parts are connected to the liquid injection tube 321, and the folding parts are used to store liquid; wherein, each folding part expands and unfolds when filled with liquid, and contracts and folds when discharged.

[0078] In the description of this application, “multiple” means at least two, such as two, three, etc., unless otherwise clearly defined.

[0079] In this embodiment, the liquid storage member 324 can adaptively adjust the volume of the temporary storage cavity 3241 by expanding or contracting the folding portions.

[0080] In other embodiments, after the power element 322 is filled with liquid, the volume of the temporary storage chamber 3241 in the liquid reservoir 324 can be controlled to drive the liquid in the liquid injection tube 321 back into the liquid reservoir 324. Specifically, the temporary storage chamber 3241 can be expanded to reduce the air pressure therein, causing the liquid in the liquid injection tube 321 to flow back into the liquid reservoir 324 due to the negative pressure. Alternatively, the temporary storage chamber 3241 can be compressed to expel the liquid from the temporary storage chamber 3241. The compression or expansion of the temporary storage chamber 3241 can be controlled manually or by providing a driver electrically connected to a control device. When the power element 322 is filled with liquid and the one-way valve 323 is closed, the driver, upon receiving a control signal from the control device, controls the increase in volume in the temporary storage chamber 3241, causing the liquid in the liquid injection tube 321 to flow back into the liquid reservoir 324 due to the pressure difference.

[0081] In this embodiment, the liquid storage part 324 is a folding bellows. After the one-way valve 323 is closed, the power part 322 draws back the liquid in the buffer chamber of the atomizer 20 and the liquid injection tube 321, and injects it into the liquid storage part 324. The folded parts expand and unfold due to the filling of liquid to isolate the liquid in the liquid storage bottle 35 from the refluxed liquid, thereby reducing the risk of contamination of the liquid in the liquid storage bottle 35.

[0082] When the liquid in the injection tube 321 flows back to the liquid storage part 324, the power part 322 injects liquid again, and the one-way valve 323 is still in a closed state. The power part 322 first pumps the liquid stored in the liquid storage part 324 to the atomizer 20 through the injection tube 321. At this time, the liquid storage part 324 shrinks and folds due to the outflow of liquid; when the liquid stored in the liquid storage part 324 is consumed to a preset amount or is finished, the one-way valve 323 opens, and the liquid storage bottle 35 is connected to the injection tube 321, so that the power part 322 can pump out the liquid in the liquid storage bottle 35 and supply it to the atomizer 20 through the injection tube 321.

[0083] In this way, the liquid that flows back in the liquid storage part 324 can be supplied to the atomizer 20 first, preventing the waste of the refluxed liquid and improving the utilization rate of the refluxed liquid. Moreover, when the liquid in the liquid storage part 324 is less, the liquid in the liquid storage bottle 35 is supplied to the atomizer 20 so that the injection process can continue.

[0084] The one-way valve 323 can be an electronic one-way valve and is connected to a control device, which controls the opening and closing of the one-way valve 323. After the power part 322 is injected with liquid, the control device controls the one-way valve 323 to close. A detection element connected to the control device can be set in the liquid storage part 324. After the detection element detects that the liquid stored in the liquid storage part 324 is consumed to a preset amount, the control device controls the one-way valve 323 to open. Or the one-way valve 323 is a pressure-sensitive one-way valve, which can control its own opening or closing according to the pressure sensing on one side. For example, it closes when the power part 322 draws back liquid and injects liquid into the liquid storage part 324, and opens again after the liquid in the liquid storage part 324 is discharged.

[0085] Please refer to Figures 5 to 7 , Figure 6 and Figure 7 Schematic diagrams of the structure of an embodiment of the one-way valve 323 provided in this application from different perspectives. In this embodiment, the one-way valve 323 opens when the pressure on the side near the injection tube 321 is less than the pressure on the side near the liquid storage bottle 35; the one-way valve 323 closes when the pressure on the side near the injection tube 321 is greater than or equal to the pressure on the side near the liquid storage bottle 35.

[0086] In one specific embodiment, the one-way valve 323 includes a silicone body 3231, which can be hemispherical in shape. A liquid passage hole 3231a is defined on the outer surface of the silicone body 3231, facing away from the liquid injection tube 321. Multiple sealing portions 3231b are positioned around the liquid passage hole 3231a on the side facing the liquid injection tube 321. The multiple sealing portions 3231b cooperate to seal the liquid passage hole 3231a. Alternatively, multiple sealing portions 3231b can be positioned around the side of the liquid passage hole 3231a facing away from the liquid injection tube 321. Preferably, the liquid passage hole 3231a extends along the axis of the silicone body 3231.

[0087] When the pressure on the side of the multiple sealing portions 3231b near the injection tube 321 is greater than or equal to the pressure on the side near the liquid storage bottle 35, the multiple sealing portions 3231b squeeze each other to seal the liquid hole 3231a, and the one-way valve 323 is in a closed state. When the pressure on the side of the multiple sealing portions 3231b near the injection tube 321 is less than the pressure on the side near the liquid storage bottle 35, the multiple sealing portions 3231b open toward the side of the injection tube 321 to open the liquid hole 3231a, and the one-way valve 323 is in an open state. Therefore, this one-way valve 323 can automatically open and close according to the difference in pressure on both sides of the one-way valve 323, without the need for connection to a control device to achieve opening and closing, thus reducing the process steps.

[0088] Specifically, when the power part 322 draws back the liquid through the injection tube 321, the pressure of the liquid reflux on one side of the multiple sealing parts 3231b causes the multiple sealing parts 3231b to squeeze each other to close the liquid hole 3231a, and then the refluxed liquid is injected into the liquid storage part 324; when the liquid supply component 32 is refilled with liquid, the liquid in the folding bellows flows out, and the folding bellows is relieved of the hydraulic restriction on its own elasticity, and it shrinks and folds when releasing the liquid, so that the liquid inside it is pumped out first by the power part 322. After all the liquid in the folding bellows is pumped out, the pressure formed on one side of the multiple sealing parts 3231b by the suction action of the power part 322 is less than the pressure on the side close to the liquid storage bottle 35, and then the multiple sealing parts 3231b release the seal on the liquid hole 3231a, so that the liquid supply bottle 35 is connected to the injection tube 321.

[0089] Furthermore, the cover portion 3231b is arranged in an arched shape. The arched convex surface of the cover portion 3231b is arranged toward the liquid injection tube 321, and the arched concave surface of the cover portion 3231b is arranged away from the liquid injection tube 321. For example, multiple cover portions 3231b can cooperate to form a hemispherical shape. By arranging the cover portion 3231b in an arched shape, the cover portion 3231b can withstand greater pressure on the side close to the liquid injection tube 321. When the pressure on the side close to the liquid injection tube 321 of the multiple cover portions 3231b is greater than or equal to the pressure on the side close to the liquid storage bottle 35, the multiple arched cover portions 3231b squeeze each other to close the liquid hole 3231a, and will not open toward the side away from the liquid injection tube 321, thereby placing the one-way valve 323 in a closed state.

[0090] In this embodiment, the silicone body 3231 may have a snap-fit groove 3231c on one side near the liquid injection tube 321. The snap-fit groove 3231c is used to secure the one-way valve 323. In this embodiment, the snap-fit groove 3231c is a closed ring, surrounding the liquid hole 3231a. In other embodiments, the snap-fit groove 3231c may also be a ring with a gap, or an irregular shape.

[0091] Please refer to Figure 8 , Figure 8 for Figure 5 A partial enlarged view. In one embodiment, the liquid supply assembly 32 further includes a connecting piece 325, which is a hollow structure and has a connecting cavity 3251. The liquid storage piece 324 and the injection tube 321 are both connected to the connecting cavity 3251. The one-way valve 323 can be set in the fluid channel between the connecting piece 325 and the liquid storage bottle 35. The one-way valve 323 can be set on the connecting piece 325, or between the connecting piece 325 and the liquid storage bottle 35, or the one-way valve 323 can be set on the liquid storage bottle 35. Thus, the one-way valve 323 can control the opening and closing of the fluid channel between the connecting piece 325 and the liquid storage bottle 35.

[0092] In this embodiment, a one-way valve 323 is provided on the connecting member 325 to open or close the liquid inlet connecting the connecting cavity 3251 and the liquid storage bottle 35. By providing the one-way valve 323 on the connecting member 325, after the power member 322 is filled with liquid and the one-way valve 323 is closed, the fluid passage between the connecting member 325 and the liquid storage bottle 35 is closed, while the liquid injection tube 321 is connected to the connecting cavity 3251, and the connecting cavity 3251 is connected to the liquid storage member 324. This allows the liquid in the liquid injection tube 321 to flow back into the liquid storage member 324 instead of back into the liquid storage bottle 35, thereby preventing contamination of the liquid storage bottle 35.

[0093] like Figure 9 and Figure 10 As shown, Figure 9 This is a schematic diagram of the structure of the connecting piece 325 provided in this application. Figure 10 for Figure 9 sectional view of the connecting piece 325.

[0094] The connecting piece 325 has a connecting cavity 3251 and a first liquid inlet hole 3253, a second liquid inlet hole 3254 and a third liquid inlet hole 3252 connected to the connecting cavity 3251, wherein the injection tube 321 is connected to the connecting cavity 3251 through the first liquid inlet hole 3253, and the liquid storage piece 324 is connected to the connecting cavity 3251 through the second liquid inlet hole 3254, and the one-way valve 323 is arranged in the third liquid inlet hole 3252, and the one-way valve 323 is used to open or close the liquid path of the third liquid inlet hole 3253.

[0095] See also Figure 8 The liquid storage part 324 and the liquid injection tube 321 are both located on the top side of the connecting part 325, and the one-way valve 323 is located on the bottom side of the connecting part 325. Therefore, after the liquid storage part 324 is filled with liquid, the hydraulic pressure formed in the connecting part 325 can seal the multiple sealing parts 3231b, so that the multiple sealing parts 3231b remain closed through the liquid hole 3231a.

[0096] Specifically, the top wall of the connecting cavity 3251 has a first liquid inlet hole 3253 and a second liquid inlet hole 3254, and the end of the injection tube 321 close to the connecting cavity 3251 is connected to the first liquid inlet hole 3253, and the end of the liquid storage part 324 close to the connecting cavity 3251 is connected to the second liquid inlet hole 3254, so that the injection tube 321 and the liquid storage part 324 are connected through the connecting cavity 3251.

[0097] When the connecting chamber 3251 is full of liquid, the liquid in the liquid injection tube 321 continues to flow back under the action of the power element 322, and the liquid in the connecting chamber 3251 can be injected into the liquid storage element 324 under the action of pressure. When the power element 322 is injected again, the liquid in the connecting chamber 3251 is consumed, and the liquid in the liquid storage element 324 automatically flows into the connecting chamber 3251 under the action of gravity for replenishment. Therefore, the liquid storage element 324 is placed on the top side of the connecting element 325, and the liquid flows into the connecting chamber 3251 by gravity. There is no need to use a control device to make the liquid in the liquid storage element 324 flow into the connecting element 325, thus simplifying the layout of the liquid supply assembly 32.

[0098] Furthermore, the one-way valve 323 is disposed on the bottom wall of the communication chamber 3251. Thus, when the power member 322 is refilled with liquid and the hydraulic pressure on the side of the one-way valve 323 within the communication chamber 3251 exceeds a preset value, the one-way valve 323 closes under the action of the hydraulic pressure, and the power member 322 first pumps out the liquid stored in the liquid reservoir 324. When the liquid stored in the liquid reservoir 324 by the one-way valve 323 is consumed to a preset amount, i.e., when the communication chamber 3251 stores liquid equal to or less than the preset amount, and the hydraulic pressure on the side of the one-way valve 323 within the communication chamber 3251 becomes less than the hydraulic pressure on the side of the one-way valve 323 within the liquid storage bottle 35, the multiple sealing portions 3231b release their seals on the liquid passage hole 3231a, and the power member 322 then draws liquid from the liquid storage bottle 35 to inject the liquid into the atomizer 20.

[0099] A snap-fit groove is provided on the side of the connecting member 325 facing away from the liquid injection tube 321, and the snap-fit groove is arranged around the third liquid inlet hole 3252. The sidewall of the snap-fit groove 3231c of the one-way valve 323 snaps into the snap-fit groove of the connecting member 325, and the sealing portion 3231b of the one-way valve 323 is disposed in the third liquid inlet hole 3252, allowing the liquid passage hole 3231a to communicate with the third liquid inlet hole 3252.

[0100] See also Figure 9 and Figure 10 In one embodiment, the connecting member 325 includes an upper cover 325a and a lower cover 325b. The upper cover 325a is disposed on a side of the lower cover 325b near the liquid injection tube 321. The upper cover 325a and the lower cover 325b enclose a connecting cavity 3251. The top wall of the upper cover 325a has a first liquid inlet hole 3253 and a second liquid inlet hole 3254 that extend through the connecting cavity 3251. Specifically, a first groove is provided on the bottom surface of the upper cover 325a near the lower cover 325b, and a second groove is provided on the bottom surface of the lower cover 325b near the upper cover 325a. The first groove and the second groove together form the connecting cavity 3251.

[0101] In other embodiments, the upper cover 325a may be provided with a first groove on its bottom surface near the lower cover 325b, and the first groove cooperates with the top surface of the lower cover 325b to form the communication cavity 3251. Alternatively, the communication member 325 may be a unitary structural member, i.e., the upper cover 325a and the lower cover 325b are integrally formed, and the communication cavity 3251 is formed in the communication member 325.

[0102] Please refer to Figure 11 , Figure 11 This is a cross-sectional view of an atomizer 20 provided in this application. Figure 11 The direction of the arrow in the middle represents the flow direction of the gas. The present application further provides an atomizer 20 , which is applied to the electronic atomization device 10 mentioned above, and can also be applied to other electronic atomization devices 10 .

[0103] The atomizer 20 includes a housing assembly 21, an atomizing assembly 22, an air outlet pipe 23, and a mounting base 24. The housing assembly 21 has a buffer chamber 213 and a mounting chamber 214 that are interconnected. The mounting chamber 214 is used to mount the atomizing assembly 22 and the mounting base 24. The buffer chamber 213 is used to store the liquid to be atomized injected by the liquid supply assembly 32. The bottom wall of the buffer chamber 213 may be provided with a liquid injection hole 215 for inserting the liquid injection pipe 321 of the liquid supply assembly 32.

[0104] Specifically, the housing assembly 21 includes a shell 211 and a cover 212. The shell 211 is provided with a buffer cavity 213, a mounting cavity 214, and a liquid injection hole 215. The cover 212 has a top wall and side walls. The top wall of the cover 212 is connected to the side walls of the cover 212, and the bottom wall and side walls of the cover 212 form the interior space of the cover 212. The side walls of the cover 212 are snap-fitted to the shell 211; the top wall of the cover 212 is spaced apart from the shell 211, and a seal 216 is provided between the bottom wall of the cover 212 and the shell 211, and is sealed by the seal 216.

[0105] The atomizer assembly 22 is used to atomize the liquid to be atomized in the buffer chamber 213. The atomizer assembly 22 is assembled in the mounting chamber 214 and is disposed on a side of the mounting base 24 near the buffer chamber 213. Specifically, the atomizer assembly 22 includes a liquid absorbing member 221, a porous base 222, a heating member 223, and a mounting member 224. Among them, one end of the mounting part 224 is arranged on the side of the mounting seat 24 close to the cache cavity 213, the porous matrix 222 is embedded in the mounting part 224, and cooperates with the mounting part 224 to form an air flow channel 225, and the end of the air flow channel 225 away from the mounting seat 24 is connected to the air nozzle 2123 on the bottom wall of the cover body 212, and the end of the air flow channel 225 close to the mounting seat 24 is connected to the air inlet of the atomizer 20, so that the air flow entering the air inlet of the atomizer 20 can flow through the air flow channel 225 of the atomizing assembly 22, and carry the aerosol atomized by the atomizing assembly 22 out of the air nozzle 2123.

[0106] The porous matrix 222 can store and direct the liquid to be atomized. The material of the porous matrix 222 can be a loose porous material such as porous ceramic, cotton layer, fiber layer, etc. In this embodiment, the material of the porous matrix 222 is porous ceramic. The shape of the porous matrix 222 can be a hollow tube with open ends, specifically, but not limited to, a cylindrical shape. In this embodiment, the porous matrix 222 is a hollow cylinder.

[0107] The heating element 223 is disposed on the inner wall of the porous ceramic. When powered, the heating element 223 generates heat and heats the liquid to be atomized, which is guided by the porous matrix 222, to produce an aerosol. The heating element 223 can be electrically connected to the battery 33 and the control device of the host 30, so that the battery 33 can provide power to the heating element 223, and the control circuit can control the heating duration and heating power of the heating element 223. The heating element 223 can be a thin film metal heating film, or it can be a heating sheet, a heating mesh, a heating wire, etc.

[0108] The liquid absorbent member 221 is used to store and guide the liquid to be atomized in the buffer chamber 213. The material of the liquid absorbent member 221 can be a loose porous material such as porous ceramics, cotton layers, and fiber layers. In this embodiment, the material of the liquid absorbent member 221 is a cotton layer. The liquid absorbent member 221 is sleeved on the outer wall of the porous base 222, and the end of the liquid absorbent member 221 close to the cover body 212 is inserted into the buffer chamber 213 so that the liquid in the buffer chamber 213 can flow into the liquid absorbent member 221, and is guided to the porous base 222 through the liquid absorbent member 221, and then guided to the heating element 223 of the porous base 222.

[0109] In this embodiment, the outlet pipe 23 includes an outlet channel 231 and a mounting slot, which are interconnected. The mounting slot is provided at the end of the outlet pipe 23 away from the air nozzle 2123. The wall of the mounting slot is sandwiched between the liquid absorbing member 221 and the porous base 222 of the atomizer assembly 22. The end of the outlet channel 231 closest to the mounting slot is connected to the airflow channel 225 of the atomizer assembly 22, while the end of the outlet channel 231 away from the mounting slot is connected to the air nozzle 2123 of the cover 212, allowing the airflow carrying aerosol in the atomizer assembly 22 to flow out of the air nozzle 2123.

[0110] Since the liquid guiding process of the liquid absorbent part 221 and the porous matrix 222 requires a certain amount of time, the liquid in the liquid absorbent part 221 will be pressurized during the process of the liquid supply component 32 supplying oil to the buffer chamber 213. Under the action of the pressurization, the liquid will enter the air flow channel 225, causing the problem of suction leakage.

[0111] Based on the above problems, the present application sets a leak hole 232 on the outlet pipe 23, and the leak hole 232 connects the buffer chamber 213 and the outlet channel 231, so that the gas in the buffer chamber 213 can flow into the outlet channel 231 through the leak hole 232, and then flow out of the atomizer 20 through the gas nozzle 2123.

[0112] Specifically, one section of the air outlet pipe 23 is disposed within the buffer cavity 213 and the mounting cavity 214 of the housing 211 and is surrounded by the buffer cavity 213. Another section of the air outlet pipe 23 extends outside the buffer cavity 213 and is disposed within the cover 212. In one embodiment, the air leakage hole 232 is disposed on the portion of the air outlet pipe 23 located within the cover 212, i.e., the air leakage hole 232 is located above the buffer cavity 213 or between the buffer cavity 213 and the air nozzle 2123. Since the air nozzle 2123 is usually facing upward when the user uses the electronic atomization device 10, this can prevent liquid in the buffer cavity 213 from flowing into the air outlet channel 231 through the air leakage hole 232 and causing leakage.

[0113] Furthermore, in this embodiment, the top wall of the buffer chamber 213 has an opening, and a gap is defined between the air outlet pipe 23 and the seal 216 in the cover 212 to prevent blockage of the air leakage hole 232, thereby allowing gas in the buffer chamber 213 to flow into the air leakage hole 232 through the opening and the gap between the air outlet pipe 23 and the seal 216. Furthermore, the housing 211 has a mounting hole 2111 at its end near the cover 212. One end of the air outlet pipe 23 near the cover 212 is disposed in the cover 212 via the mounting hole 2111. Furthermore, a gap is defined between the air outlet pipe 23 and the mounting hole 2111, allowing gas in the buffer chamber 213 to flow into the air leakage hole 232 through the gap between the air outlet pipe 23 and the mounting hole 2111.

[0114] The overall structural layout of the atomizing device is not limited to this embodiment, and the components contained therein may also have other distribution patterns. For example, in this embodiment, the battery 33 and the liquid storage bottle 35 are arranged left and right. In other embodiments, the battery 33 and the liquid storage bottle 35 may also be arranged up and down.

[0115] The above is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
