Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to an electronic atomizer with controllable oil filling. Background Technology

[0002] An electronic atomizer includes an oil reservoir and an atomizing chamber. The oil reservoir contains an atomizing matrix, and the atomizing chamber is connected to the oil reservoir. The atomizing chamber is equipped with an atomizing element that heats the atomizing matrix to generate an aerosol.

[0003] In some existing e-cigarettes, the atomizing chamber and the tank are combined, while in others they are separate units. Both require the e-liquid in the tank to be supplied to the atomizer. However, once the e-liquid in the tank is depleted, users need to replace the tank or manually refill it. This can lead to leakage during long-term storage or use, resulting in a poor user experience. Utility Model Content

[0004] The main purpose of this invention is to propose an electronic atomizer with controllable oil filling, which enables users to control the oil intake of the oil storage chamber.

[0005] To achieve the above objectives, this application provides an electronic atomizer with controllable e-liquid filling, comprising:

[0007] A sensor, located inside the housing, is used to detect the user's suction action;

[0008] The control component is electrically connected to the sensor;

[0009] A conveying component, electrically connected to the control component, is used to convey fluid;

[0010] After detecting the user's suction action, the control component controls the delivery component to deliver the fluid in the oil supply chamber to the oil storage chamber.

[0011] The aforementioned electronic atomizer can maintain a liquid flow barrier between the oil reservoir and the atomizing chamber before being controlled by the user, allowing the user to independently control the timing or flow rate of the liquid material between the oil reservoir and the atomizing chamber.

[0012] In some embodiments, the outer casing includes a separable oil storage tank and an oil supply tank, wherein the oil storage tank forms an oil storage cavity and the oil supply tank forms an oil supply cavity, and the conveying assembly is capable of connecting the oil storage tank and the oil supply tank.

The first movable member is capable of moving between a position away from and a position close to the oil outlet. After the conveying assembly is connected to the oil supply chamber, the conveying assembly drives the first movable member away from the oil outlet to open the oil supply chamber. The first movable member can move from a position away from the oil outlet to a position close to the oil outlet to close the oil supply chamber.

[0014] In some embodiments, the oil supply tank is provided with an elastic element, one end of which is connected to the oil storage tank and the other end is connected to the first movable element. The elastic element uses its elasticity to make the first movable element fit tightly against the oil outlet and close the oil outlet.

[0015] In some embodiments, the oil storage tank is provided with a second movable member and an air pipe that is at least partially connected to the outside of the outer shell. The air pipe and the oil storage tank define at least a portion of the oil storage cavity. The air pipe is provided with an oil inlet that is connected to the oil storage cavity. The second movable member is movable between a position away from and a position close to the oil inlet. The second movable member is movable to open the oil inlet after moving away from the oil inlet. The second movable member is movable to close the oil inlet after being pressed against the oil inlet.

[0016] In some embodiments, the second movable member includes a transmission part and an operating part. The transmission part is movably disposed inside the oil storage tank and abuts against the gas pipe, and the operating part is disposed outside the oil storage tank and connected to the transmission part.

[0017] In some embodiments, the operating unit is a motor, and the control component is electrically connected to the operating unit; after detecting the user's suction action, the control component controls the operating unit to drive the transmission unit to close or open the oil inlet.

[0018] In some embodiments, the delivery assembly includes a pump having a pump tube, one end of which is connected to the oil supply tank and the other end of which is connected to the oil storage tank.

[0019] In some embodiments, the conveying assembly includes a feeding pipe, a worm gear, and a motor. One end of the feeding pipe is connected to the oil supply tank, and the other end is connected to the oil storage tank. The worm gear is disposed in the feeding pipe. The motor has an input end and an output end. The input end is electrically connected to the control assembly, and the output end is connected to the worm gear to drive the worm gear to convey liquid to the oil storage tank.

[0020] In some embodiments, the oil storage tank is provided with a vent, and a one-way valve is installed at the vent. When the air pressure in the oil storage chamber is greater than atmospheric pressure, the air in the oil storage chamber is discharged through the one-way valve.

[0021] Compared with the prior art, the electronic atomizer described in this application can control the fluid flow between the oil tank and the atomizing chamber according to the user's operation behavior, allowing the user to independently control the timing or flow rate of the liquid material between the oil tank and the atomizing chamber when liquid material needs to be atomized; after the user has used up the liquid material in the oil tank, the user can also refill the oil tank with liquid material through the supply tank to increase the usage time of the electronic atomizer, and the supply tank can also be a detachable component, which the user can replace.

[0034] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] Electronic atomizers can be used in various fields, such as medical atomization, beauty atomization, and cigarette replacement. They mainly use heated liquid materials to generate aerosols, and the liquid materials can be liquid matrices containing or without nicotine.

[0037] This application provides a controllable e-cigarette, comprising a housing, a sensor, a control component, and a delivery component. The housing contains a reservoir for storing liquid atomized material, a supply chamber, and an atomization chamber for forming an aerosol. The reservoir is fluidly connected to both the atomization chamber and the supply chamber. The sensor is connected to the control component and detects the user's inhalation actions, such as turning on the e-cigarette to atomize liquid material, or actions causing airflow or pressure deformation when inhaling aerosol. The delivery component is electrically connected to the control component to deliver the fluid. Upon detecting the user's inhalation action, the control component controls the delivery component to deliver the liquid material from the supply chamber to the reservoir. The liquid material then flows into the atomization chamber and is atomized to generate an aerosol.

[0038] like Figure 1 As shown, the outer shell of an electronic atomizer can be molded from a single, integral shell. For example... Figure 5 As shown, the outer shell of an electronic atomizer can also be composed of multiple separable shells assembled together. Among them, a first shell with an oil storage chamber 10, a second shell with an oil supply chamber 20, and a third shell 50 with a delivery assembly 40 are provided. The third shell 50 is provided with a receiving cavity 51, which can accommodate at least a portion of the first shell and the second shell.

[0039] See Figure 1 As shown, the outer shell is provided with a nozzle 100 and an air inlet communicating with the nozzle 100. Inside the outer shell, an oil storage chamber 11 and an oil supply chamber 21 are formed. An air pipe 30 is provided inside the outer shell, passing through the oil storage chamber 11. One end of the air pipe 30 is connected to the nozzle 100, and the other end is connected to the air inlet. An atomizing core 31 is provided inside the air pipe 30, and an oil inlet is provided on the air pipe 30 communicating with the oil storage chamber 11. Of course, the ability to detach and assemble the first and second shells is a design feature readily conceived by those skilled in the art.

[0040] For example, an electronic atomizer includes a detachable e-liquid reservoir 10 and an e-liquid supply reservoir 20, wherein the e-liquid reservoir 10 has a first housing that forms at least a portion of the outer shell of the electronic atomizer, and the e-liquid supply reservoir 20 has a second housing that forms at least a portion of the outer shell of the electronic atomizer. Figure 2 As shown, the first housing has a nozzle 100 at one end and a first oil inlet 32. An oil storage chamber 11 is formed inside the first housing, and the first oil inlet 32 ​​communicates with the oil storage chamber 11. An air pipe 30 is disposed in the oil storage chamber 11, with one end connected to the nozzle 100 and the other end connected to the outside of the oil storage tank 10 and open to the atmosphere. The air pipe 30 has a second oil inlet 14, and an atomizing core 31 is disposed inside the air pipe 30. The outer wall of the air pipe 30 and the inner wall of the oil storage tank 10 define the oil storage chamber 11. An oil supply chamber 21 is formed inside the second housing. The delivery assembly 40 and the control assembly can be installed on either the first housing or the second housing.

[0041] The oil storage tank 10 is provided with a second movable part 12, which can move between a position away from the oil inlet and a position close to the oil inlet. The second movable part 12 can open the second oil inlet 14 after moving away from the oil inlet; the second movable part 12 can close the second oil inlet 14 after sticking to it.

[0042] In some embodiments, the second active element 12 can be directly operated by the user. For example... Figure 2As shown, the second movable component 12 includes a transmission part and an operating part. The transmission part is movably disposed inside the oil storage tank 10 and abuts against the air pipe 30, while the operating part is disposed outside the oil storage tank 10 and connected to the transmission part. For example, the operating part is a motor 42, and the transmission part is the power output shaft of the motor 42. The power output shaft is rotatable or retractable, and the control component is electrically connected to the motor 42. After detecting the user's suction action, the control component controls the motor 42 to drive the transmission part to move relative to the air pipe 30, so that the transmission part can be close to or away from the second oil inlet 14 during the contact between the transmission part and the air pipe 30.

[0043] In some embodiments, the oil storage tank 10 is provided with a vent, and a one-way valve 13 is installed at the vent. When the air pressure in the oil storage chamber 11 is greater than atmospheric pressure, the air in the oil storage chamber 11 is discharged through the one-way valve 13. The liquid material in the oil storage chamber 11 will not be leaked due to the high pressure in the oil storage chamber 11.

[0044] In some embodiments, the oil supply tank 20 is provided with an oil outlet 22, and a first movable member 23 is provided at the oil outlet 22. The first movable member 23 is movable between a position relatively far from the oil outlet 22 and a position close to the oil outlet 22. Figure 2 As shown, the initial position of the first movable part 23 is set near the oil outlet 22, and the oil supply chamber 21 is in a closed state; as Figure 5 As shown, an electronic atomizer connects the oil supply chamber 20 and the oil storage chamber 10 via a conveying component 40. After the conveying component 40 is connected to the oil supply chamber 20, the conveying component 40 drives the first movable part 23 away from the oil outlet 22 and opens the oil supply chamber 21. The liquid material is sent to the oil storage chamber 11 after the conveying component 40 is activated.

[0045] In some embodiments, the oil supply tank 20 is further provided with a mounting groove near the oil outlet 22. A spring 24 and a first movable member 23 are assembled in the mounting groove. One end of the spring 24 is connected to the oil storage tank 10, and the other end is connected to the first movable member 23. Figure 3 As shown, the first movable part 23 approaches and blocks the oil outlet 22 by the elastic force of the spring 24, and the oil supply chamber 21 is in a sealed state. The oil supply chamber 20 in a sealed state can be transported and stored independently.

[0046] Furthermore, the first movable part 23 is provided with a sealing element 25, which is used to abut against the oil supply tank 20 and seal the oil outlet 22 after the first movable part 23 approaches the oil outlet 22.

[0047] A sensor, at least partially housed within the housing, is electrically connected to the control components. For example, an airflow sensor has a first side and a second side facing away from each other in the longitudinal direction. The airflow sensor is mounted on one side of the gas flow channel within the housing, and this side senses the airflow flowing through the housing during the user's inhalation. The airflow sensor determines the user's inhalation action when the pressure difference caused by the inhaled aerosol exceeds a preset threshold, and outputs an electrical signal. The control components then control the delivery assembly 40 to draw liquid material from the supply chamber 21 into the storage chamber 11 based on the electrical signal. Alternatively, a microswitch can be used, having an electrically connected trigger end and a signal end. The trigger end is exposed outside the housing for user contact, while the signal end is mounted inside the housing and electrically connected to the control components. After the user contacts the trigger end to power on the electronic atomizer, the signal end outputs an electrical signal, and the control components control the delivery assembly 40 to draw liquid material from the supply chamber 21 into the storage chamber 11 based on the electrical signal. The user can autonomously control the timing or flow rate of liquid material between the storage chamber 10 and the atomizing chamber through their inhalation action.

[0048] The delivery assembly 40 includes a pump having an inlet and an outlet for supplying liquid, the inlet being connected to an oil supply tank 20 and the outlet being connected to an oil storage tank 10.

[0049] like Figures 3-4 As shown, the conveying assembly 40 includes a feed pipe 401, a worm gear 41, and a motor 42. Combined with... Figure 5 As shown, one end of the feeding pipe 401 is connected to the oil supply tank 20, and the other end is connected to the oil storage tank 10. A worm gear 41 is installed in the feeding pipe 401. The motor 42 has a power input end and an output end. The input end is electrically connected to the control component, and the output end is connected to the worm gear 41 to drive the worm gear 41 to rotate. Figure 4 and Figure 5 As shown, the arrows and dashed lines indicate the flow direction of the liquid material. The liquid material moves between the teeth of the spiral as the worm gear 41 rotates until it is conveyed into the oil storage tank 10 through the second oil inlet 14.

[0050] Understandably, users can control the fluid flow between the oil reservoir 10 and the atomizing chamber based on their suction action. This allows users to control the timing or flow rate of liquid material between the oil reservoir 10 and the atomizing chamber when they need to atomize liquid material. After the user has used up the liquid material in the oil reservoir 10, the user can also refill the oil reservoir 10 with liquid material through the oil supply tank 20 to increase the usage time of the electronic atomizer. Moreover, the oil supply tank 20 can also be a detachable component, allowing the user to replace it.

[0051] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
