Description

Technical Field

[0001] The present application relates to the technical field of electronic cigarettes, and in particular to an electronic atomizer. Background Art

[0002] E-cigarettes are electronic products that mimic cigarettes. They convert an aerosol-generating medium into vapor through atomization and other methods, which is then inhaled by the user. They produce a similar smoke, taste, and feel to cigarettes. E-cigarettes come in various designs, including one with a separate oil tank and oil bottle. The oil bottle contains the aerosol-generating medium, which is used to refill the oil tank.

[0003] In the prior art, there are two main methods for replenishing aerosol-generating medium from an oil bottle to the oil tank: 1. Positioning the oil bottle upside down allows the aerosol-generating medium to automatically flow into the oil tank; 2. Using a guide medium, such as cotton or ceramic, to guide the aerosol-generating medium from the oil bottle to the oil tank. The newly replenished aerosol-generating medium has a lower temperature, and since both of these methods automatically replenish the aerosol-generating medium in real time, the added aerosol-generating medium during e-cigarette operation can affect the temperature uniformity of the aerosol-generating medium within the oil tank, thereby affecting the atomization efficiency of the aerosol-generating medium.

[0036] E-cigarettes are electronic products that mimic cigarettes. They convert an aerosol-generating medium into vapor through atomization and other methods, which is then inhaled by the user. They produce a similar smoke, taste, and feel to cigarettes. E-cigarettes come in various designs, including one with a separate oil tank and oil bottle. The oil bottle contains the aerosol-generating medium, which is used to refill the oil tank.

[0037] In the prior art, there are two main methods for replenishing aerosol-generating medium from an oil bottle to the oil tank: 1. Positioning the oil bottle upside down allows the aerosol-generating medium to automatically flow into the oil tank; 2. Using a guide medium, such as cotton or ceramic, to guide the aerosol-generating medium from the oil bottle to the oil tank. The newly replenished aerosol-generating medium has a lower temperature, and since both of these methods automatically replenish the aerosol-generating medium in real time, the added aerosol-generating medium during e-cigarette operation can affect the temperature uniformity of the aerosol-generating medium within the oil tank, thereby affecting the atomization efficiency of the aerosol-generating medium.

[0038] In view of the above problems, an embodiment of the present application provides an electronic atomizer, which can add sufficient aerosol generating medium to the oil tank when needed, so that the temperature of the aerosol generating medium in the oil tank is more uniform.

[0039] In order to illustrate the technical solution of the present application, the following description is given with reference to specific drawings and embodiments.

[0040] Please refer to Figure 1 and Figure 4An embodiment of the present application provides an electronic atomizer, including a first chamber 121 , an atomizing core 2 , a second chamber 131 and a pump body assembly 3 .

[0041] The first chamber 121 is used to accommodate an aerosol-generating medium; the atomizer core 2 is arranged in the first chamber 121, and the atomizer core 2 is used to heat the aerosol-generating medium in the first chamber 121 to generate an aerosol; the second chamber 131 is used to accommodate an aerosol-generating medium; one end of the pump body assembly 3 is connected to the first chamber 121, and the other end of the pump body assembly 3 is connected to the second chamber 131; wherein, the pump body assembly 3 is used to replenish the aerosol-generating medium in the second chamber 131 into the first chamber 121.

[0042] Since the pump body assembly 3 is used to replenish the aerosol generating medium in the second chamber 131 into the first chamber 121, the pump body assembly 3 can be started when the aerosol generating medium in the first chamber 121 is exhausted or is about to be exhausted, and the pump body assembly 2 can replenish sufficient aerosol generating medium into the first chamber 121, so that the aerosol generating medium in the first chamber 121 can be used for a longer time, thereby eliminating the need to replenish the aerosol generating medium into the first chamber 121 in real time, so that the temperature of the aerosol generating medium in the first chamber 121 is more uniform, thereby improving the atomization efficiency of the aerosol generating medium in the first chamber 121.

[0043] Please refer to Figure 1 and Figure 4 The electronic atomizer of the embodiment of the present application also includes a third chamber 14 for accommodating a power supply assembly. To facilitate electrical connection between the power supply assembly and the atomizing core 2 in the first chamber 121, the third chamber 14 is located on the lower side of the first chamber 121 (the side opposite to the Y direction in the figure); and because the battery in the power supply assembly is relatively large, the embodiment of the present application chooses to set the second chamber 131 on the right side of the third chamber 14 (the side in the X direction in the figure), and set the pump body assembly 3 on the right side of the first chamber 121 (the side in the X direction in the figure), so that the pump body assembly 3 is connected to the first chamber 121 and the second chamber 131 respectively, and can also reduce the overall volume of the electronic atomizer and make the structure of the electronic atomizer more compact.

[0044] Please refer to Figure 1 In some embodiments, the electronic atomizer further includes a shell assembly, in which the first chamber 121 and the second chamber 131 are both formed; the pump body assembly 3 is disposed in the shell assembly, and the pump body assembly 3 has a protrusion 322 protruding from the shell assembly, and the pump body assembly 3 is configured to replenish the aerosol generating medium in the second chamber 131 into the first chamber 121 when the protrusion 322 is accommodated in the shell assembly under the action of external force.

[0045] In the above embodiment, the pump assembly 3 is a manual pump. When the manual pump is pressed, the manual pump absorbs the aerosol-generating medium in the second chamber 131 and delivers the aerosol-generating medium to the first chamber 121. The manual pump protrudes from the housing assembly to facilitate the user's pressing.

[0046] It should be noted that the capacity of the manual pump refers to the volume of aerosol-generating medium that the manual pump can extract or deliver after pressing the manual pump. The capacity of the manual pump is fixed, so a fixed amount of aerosol-generating medium can be added to the first chamber 121. Therefore, the capacity of the manual pump can be designed based on the volume of the first chamber 121 to improve the accuracy of adding aerosol-generating medium to the first chamber 121.

[0047] Please refer to Figure 2 In some embodiments, the pump body assembly 3 (manual pump) includes a manual pump core 31 and a pressing piece 32 arranged in the shell assembly, and a protrusion 322 is formed on the pressing piece 32; a first oil outlet channel 321 is provided in the pressing piece 32, one end of the first oil outlet channel 321 is connected to the first chamber 121, and the other end of the first oil outlet channel 321 is connected to the manual pump core 31, wherein the manual pump core 31 is connected to the second chamber 131.

[0048] In the above embodiment, the input end of the manual pump core 31 (at the one-way valve 312 in the figure) and the output end of the manual pump core 31 (the end of the first plunger 3132 facing away from the sealing plug 3133 in the figure) are arranged relative to each other in the Y direction. The input end of the manual pump core 31 is located in the second chamber 131, and the output end of the manual pump core 31 protrudes from the second chamber 131 in the Y direction. The pressing member 32 is connected to the output end of the manual pump core 31, and the protrusion 322 on the pressing member 32 protrudes from the housing assembly in the Y direction. With this arrangement, under the action of an external force, the pressing member 32 can drive the output end of the manual pump core 31 to move in a direction opposite to the Y direction, so that the manual pump core 31 can absorb the aerosol-generating medium in the second chamber 131 and the output end of the manual pump core 31 can output the aerosol-generating medium.

[0049] Please refer to Figure 1 There is a certain distance between the output end of the manual pump core 31 (the end of the first plunger 3132 facing away from the sealing plug 3133 in the figure) and the first chamber 121, so an additional connecting component is required to connect the output end of the manual pump core 31 and the first chamber 121. In the above embodiment, by providing a first oil outlet channel 321 on the pressing member 32, which is connected to the output end of the manual pump core 31 and the first chamber 121 respectively, the space in the pressing member 32 can be fully utilized, making the structure of the electronic atomizer of the embodiment of the present application more compact.

[0050] Please refer to Figure 1 and Figure 3 In some embodiments, the shell assembly includes a shell body 11, a heating cup 12 and an oil bottle 13. The heating cup 12 and the oil bottle 13 are both arranged on the shell body 11, the first chamber 121 is formed in the heating cup 12, and the second chamber 131 is formed in the oil bottle 13; the manual pump core 31 is arranged in the oil bottle 13, the pressing piece 32 is slidably arranged on the shell body 11, and the manual pump core 31 is inserted into the first oil outlet channel 321.

[0051] Please refer to Figure 3 The shell body 11 includes a receiving portion 111 and a guide portion 112. The guide portion 112 is located above the receiving portion 111 (on one side of the Y direction). The receiving portion 111 is provided with a cavity 1111 for placing the oil bottle 13, and the guide portion 112 is provided with a sliding groove 1121 for the pressing member 32 to slide through.

[0052] The oil bottle 13 is disposed in the cavity 1111 on the receiving portion 111, and the manual pump core 31 is disposed in the oil bottle 13. The manual pump core 31 covers and seals the opening of the oil bottle 13, so that the aerosol-generating medium in the oil bottle 13 can only be discharged through the manual pump core 31, thereby preventing the oil bottle 13 from leaking.

[0053] The input end of the manual pump core 31 is located in the oil bottle 13 , and the output end of the manual pump core 31 protrudes from the receiving portion 111 in the Y direction. The output end of the manual pump core 31 is inserted into the first oil outlet channel 321 on the pressing member 32 .

[0054] The pressing member 32 includes a channel portion 233 and a protrusion 322. The channel portion 233 can slide through the slide groove 1121 on the guide portion 112, and the channel portion 233 is connected to the output end of the manual pump core 31. The protrusion 322 is located on the side of the guide portion 112 close to the Y direction, and the protrusion 322 protrudes from the shell assembly.

[0055] Among them, the width of the protrusion 322 is greater than the width of the channel portion 233. Through the above arrangement, when the protrusion 322 is accommodated in the shell assembly under the action of external force, the upper surface of the guide portion 112 can stop the protrusion 322 to prevent the pressing member 32 from sliding a large distance and causing the manual pump core 31 to be squeezed and damaged.

[0056] Please refer to Figure 3 In the above embodiment, the shell body 11 also includes a first support portion 113 and a second support portion 114. The first support portion 113 is located above the second support portion 114 (on one side of the Y direction). The first support portion 113 is connected to the guide portion 112, and the second support portion 114 is connected to the accommodating portion 111. The heating cup 12 is set on the first support portion 113, and the battery assembly 5 is set on the second support portion 114.

[0057] Please refer to Figure 1 The shell assembly also includes an upper shell 15 and a lower shell 16. The lower shell 16 is arranged on the outer peripheral side of the shell body 11, and the lower shell 16 blocks the battery assembly 5 and the oil bottle 13. The lower shell 16 and the shell body 11 are enclosed to form the above-mentioned third chamber 14. The upper shell 15 is arranged on the outer peripheral side of the shell body 11, and the upper shell 15 blocks the heating cup 12. The upper shell 15 and the lower shell 16 are detachably connected.

[0058] Please refer to Figure 1 In some embodiments, the pump body assembly 3 further includes an oil outlet hose 33 , one end of the oil outlet hose 33 is plugged into the end of the first oil outlet channel 321 away from the manual pump core 31 , and the other end of the oil outlet hose 33 is plugged into the heating cup 12 .

[0059] When the pressing member 32 slides under the action of external force, the first oil outlet channel 321 will move relative to the first chamber 121. In the above embodiment, by providing an oil outlet hose 33, and connecting the oil outlet hose 33 to the pressing member 32 and the heating cup 12 respectively, the oil outlet hose 33 is elastic and can be bent and deformed. Therefore, when the pressing member 32 slides under the action of external force, the oil outlet hose 33 can be deformed, ensuring that the first oil outlet channel 321 and the first chamber 121 always remain connected.

[0060] Please refer to Figure 1 and Figure 2 In some embodiments, the manual pump core 31 includes a manual pump body 311, a one-way valve 312, a plunger 313 and a first elastic member 314; the manual pump body 311 is provided with a liquid inlet cavity 3111 for accommodating an aerosol generating medium; the plunger 313 is slidably connected to the liquid inlet cavity 3111, and the plunger 313 is provided with a second oil outlet channel 3131, and the second oil outlet channel 3131 is connected to the first oil outlet channel 321 and the liquid inlet cavity 3111 respectively. The plunger 313 is connected to the pressing member 32, and driven by the pressing member 32, the plunger 313 can overcome the resistance of the first elastic member 314 and slide relative to the manual pump body 311 to compress the space in the liquid inlet chamber 3111; the one-way valve 312 is arranged in the liquid inlet chamber 3111, and the one-way valve 312 is configured to connect the second chamber 131 and the liquid inlet chamber 3111 when the air pressure in the liquid inlet chamber 3111 is lower than the air pressure in the second chamber 131.

[0061] In the above embodiment, when the pressing member 32 is accommodated in the housing assembly under the action of external force, the plunger member 313 overcomes the resistance of the first elastic member 314 and slides relative to the manual pump body 311 to compress the space in the liquid inlet chamber 3111 under the drive of the pressing member 32; since the plunger member 313 is provided with a second oil outlet channel 3131, the second oil outlet channel 3131 is connected to the first oil outlet channel 321 and the liquid inlet chamber 3111, so the plunger member 313 can squeeze the aerosol generating medium in the liquid inlet chamber 3111 into the second oil outlet channel 3131 and the first oil outlet channel 321, so that the aerosol generating medium in the liquid inlet chamber 3111 flows into the first chamber 121 through the second oil outlet channel 3131, the first oil outlet channel 321 and the oil outlet hose 33.

[0062] The plunger 313 overcomes the resistance of the first elastic member 314, which means that when the plunger 313 slides relative to the manual pump body 311 to compress the space in the liquid inlet chamber 3111, the plunger 313 will squeeze or stretch the first elastic member 314. Therefore, after the external force is removed, the first elastic member 314 returns to its original shape under the action of its own elastic force and can drive the plunger 313 to slide relative to the manual pump body 311 to return to its original shape in the space in the liquid inlet chamber 3111. For example, please refer to Figure 2 In some embodiments, a first elastic member 314 is disposed within the liquid inlet chamber 3111, with one end of the first elastic member 314 connected to the plunger 313, and the other end of the first elastic member 314 abutting against the inner wall of the liquid inlet chamber 3111. When the plunger 313 slides relative to the manual pump body 311 in a direction opposite to the Y direction to compress the space within the liquid inlet chamber 3111, the plunger 313 squeezes the first elastic member 314. After the external force is removed, the first elastic member 314 stretches and returns to its original shape under its own elastic force. Under the thrust of the first elastic member 314, the plunger 313 slides relative to the manual pump body 311 in the Y direction to return to its original shape within the liquid inlet chamber 3111.

[0063] It should be noted that when the space inside the liquid inlet chamber 3111 returns to its original state, the air pressure inside the liquid inlet chamber 3111 will decrease, and the air pressure inside the liquid inlet chamber 3111 will be lower than the air pressure inside the second chamber 131. At this time, the one-way valve 312 opens and connects the second chamber 131 and the liquid inlet chamber 3111, so that the aerosol generating medium in the second chamber 131 enters the liquid inlet chamber 3111 to increase the air pressure inside the liquid inlet chamber 3111. When the air pressure inside the liquid inlet chamber 3111 is equal to the air pressure inside the second chamber 131, the one-way valve 312 closes.

[0064] Please refer to Figure 2The one-way valve 312 can be a ball valve, which is disposed in the liquid inlet chamber 3111. The first elastic member 314 abuts against the ball valve to prevent it from moving freely within the liquid inlet chamber 3111. When the air pressure within the liquid inlet chamber 3111 is lower than the air pressure within the second chamber 131, the ball valve, driven by the aerosol-generating medium in the second chamber 131, overcomes the resistance of the first elastic member 314 and moves in the Y direction, thereby connecting the second chamber 131 with the liquid inlet chamber 3111. As the aerosol-generating medium flows in, the air pressure within the liquid inlet chamber 3111 gradually increases. When the air pressure within the liquid inlet chamber 3111 equals the air pressure within the second chamber 131, the first elastic member 314 returns to its original state under the action of its own elastic force, and the first elastic member 314 drives the ball valve to move in the direction opposite to the Y direction, thereby closing the one-way valve 312.

[0065] Please refer to Figure 1 and Figure 2 In some embodiments, the manual pump body 311 is disposed in the second chamber 131, and the manual pump body 311 seals the opening of the second chamber 131. An air intake chamber 3112 communicating with the external space is also provided in the manual pump body 311. When the plunger 313 overcomes the resistance of the first elastic member 314 and slides relative to the manual pump body 311 to the space in the compressed liquid inlet chamber 3111, the air intake chamber 3112 can be communicated with the second chamber 131.

[0066] It should be noted that when the aerosol generating medium in the first chamber 121 enters the liquid inlet chamber 3111, the air pressure in the first chamber 121 will decrease, which is not conducive to the flow of the aerosol generating medium. In the embodiment of the present application, when the plunger 313 overcomes the resistance of the first elastic member 314 and slides relative to the manual pump body 311 to compress the space in the liquid inlet chamber 3111, the second chamber 131 is connected to the external space with the help of the air inlet chamber 3112, so that the air pressure in the second chamber 131 is equal to the atmospheric pressure, so that the aerosol generating medium in the second chamber 131 can flow smoothly into the liquid inlet chamber 3111.

[0067] Please refer to Figure 1 and Figure 2 In some embodiments, the manual pump body 311 is provided with an air inlet hole 3113 connecting the liquid inlet chamber 3111 and the second chamber 131, and the air inlet hole 3113 is located on the side of the plunger 313 away from the air inlet chamber 3112. When the plunger 313 overcomes the resistance of the first elastic member 314 and slides relative to the manual pump body 311 to compress the space in the liquid inlet chamber 3111, the air inlet hole 3113 can be connected with the air inlet chamber 3112.

[0068] In the above embodiment, in the initial state, the plunger 313 is located between the air inlet chamber 3112 and the air inlet hole 3113, or the plunger 313 blocks the air inlet hole 3113 to block the communication between the air inlet chamber 3112 and the air inlet hole 3113. When the plunger 313 overcomes the resistance of the first elastic member 314 and slides relative to the manual pump body 311 to the space within the compressed liquid inlet chamber 3111, the plunger 313 can slide to the side of the air inlet hole 3113 away from the air inlet chamber 3112, so that the air inlet hole 3113 is connected to the air inlet chamber 3112, thereby connecting the second chamber 131, the air inlet hole 3113, the air inlet chamber 3112 and the external space in sequence.

[0069] Please refer to Figure 2 The plunger member 313 includes a first plunger 3132, a sealing plug 3133 and a second plunger 3134. The sealing plug 3133 is slidably connected to the inner wall of the liquid inlet chamber 3111. The second plunger 3134 is connected to the sealing plug 3133, and the end of the second plunger 3134 away from the sealing plug 3133 protrudes from the manual pump body 311. The first plunger 3132 is connected to the end of the sealing plug 3133 away from the second plunger 3134, and the first elastic member 314 is sleeved on the outer peripheral side of the first plunger 3132. The second oil outlet channel 3131 sequentially penetrates the second plunger 3134, the sealing plug 3133 and the first plunger 3132.

[0070] In the above embodiment, the first elastic member 314 is a spring, and the first elastic member 314 is sleeved on the outer peripheral side of the first plunger 3132, which can not only limit the position of the first elastic member 314, making the structure inside the manual pump core 31 more compact, but also limit the deformation direction of the first elastic member 314, so that the manual pump core 31 can work more accurately.

[0071] Please refer to Figure 2 In the above embodiment, the first piston 3132 includes a first main body portion 31321 and a first stop portion 31322. The first main body portion 31321 is connected to the sealing plug 3133. The first stop portion 31322 is arranged on the outer peripheral side of the first main body portion 31321. The first elastic member 314 is sleeved on the first main body portion 31321, and one end of the first elastic member 314 is abutted against the first stop portion 31322.

[0072] Please refer to Figure 2 The manual pump core 31 also includes a second elastic member 315, the second plunger 3134 includes a second main body portion 31341 and a second stop portion 31342, the second main body portion 31341 is connected to the sealing plug 3133, and the second stop portion 31342 is arranged on the outer peripheral side of the second main body portion 31341, and the two ends of the second elastic member 315 are respectively abutted against the second stop portion 31342 and the sealing plug 3133.

[0073] After the external force is lost, the first elastic member 314 stretches and returns to its original shape under the action of its own elastic force. The plunger 313 slides in the Y direction relative to the manual pump body 311 under the thrust of the first elastic member 314 to the space inside the liquid inlet chamber 3111 to return to its original shape, that is, the plunger 313 slides in the Y direction relative to the manual pump body 311 under the thrust of the first elastic member 314 to the second stop portion 31342 against the upper wall of the air inlet chamber 3112. By providing the second elastic member 315, it can play a buffering role when the second stop portion 31342 just against the upper wall of the air inlet chamber 3112, thereby preventing damage to the manual pump core 31.

[0074] Please refer to Figure 1 and Figure 2 In some embodiments, the pump body assembly 3 further includes a first oil inlet pipe 34 , which is disposed in the second chamber 131 and communicates with the manual pump core 31 .

[0075] Through the above arrangement, the end of the first oil inlet pipe 34 facing away from the manual pump core 31 is located at the bottom of the oil bottle 13, so that the aerosol generating medium located at the bottom of the oil bottle 13 can also enter the liquid inlet chamber 3111 through the first oil inlet pipe 34, thereby improving the utilization rate of the aerosol generating medium in the oil bottle 13.

[0076] Please refer to Figure 4 In some embodiments, the electronic atomizer further includes a control component 4, which includes a button 41 and a main board 42, the main board 42 being electrically connected to the button 41 and the pump body component 3 respectively, and the control component 4 is configured such that when the button 41 is pressed, the main board 42 drives the pump body component 3 to work for a preset time.

[0077] In the above embodiment, when button 41 is pressed, pump assembly 3 automatically replenishes aerosol-generating medium into first chamber 121, eliminating the need for manual labor. Furthermore, because control assembly 4 is configured such that when button 41 is pressed, mainboard 42 drives pump assembly 3 to operate for a predetermined time, the output of control assembly 4 can be controlled, thereby allowing a fixed amount of aerosol-generating medium to be replenished into first chamber 121.

[0078] Optionally, the preset time may be 1 s, 2 s or 5 s. The length of the preset time may be designed according to the volume of the first chamber 121 and the power of the pump assembly 3 .

[0079] Please refer to Figure 4 The pump body assembly 3 includes an electric pump 35, a second oil inlet pipe 36 and an oil outlet pipe 37. The second oil inlet pipe 36 is arranged in the second chamber 131, and the second oil inlet pipe 36 is connected to the electric pump 35. The oil outlet pipe 37 is respectively connected to the electric pump 35 and the first chamber 121. The electric pump 35 is electrically connected to the main board 42.

[0080] Through the above arrangement, the end of the second oil inlet pipe 36 facing away from the manual pump core 31 is located at the bottom of the oil bottle 13, so that the aerosol generating medium located at the bottom of the oil bottle 13 can also enter the electric pump 35 through the second oil inlet pipe 36, thereby improving the utilization rate of the aerosol generating medium in the oil bottle 13.

[0081] The electric pump 35 consists of an electric motor, a hydraulic pump, a transmission, and a control system. The electric pump 35 operates by using the electric motor to drive the hydraulic pump. When button 41 is pressed, the mainboard 42 activates the control system in the electric pump 35, which in turn activates the control system motor. This power is then transmitted to the hydraulic pump via the transmission, causing the hydraulic pump to start operating. The hydraulic pump draws in the aerosol-generating medium and discharges it through a pipeline. The electric motor serves as the power source to drive the hydraulic pump; the hydraulic pump is responsible for drawing in and discharging the aerosol-generating medium; the transmission transmits power; and the control system monitors and regulates the operating status of the electric pump 35.
