Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an atomizer and electronic atomization device. Background Technology

[0002] Electronic atomizing devices, also known as electronic cigarettes, are electronic products that mimic traditional cigarettes. They work by heating and atomizing tobacco-flavored e-liquid into a vapor form for user consumption. Currently, with technological advancements, electronic cigarettes have evolved from simple electronic cigarette devices into high-powered products with independent main units and atomizers. Because the e-liquid storage capacity of the atomizer's reservoir is limited, it needs to be refilled promptly through a small hole. This process is prone to leakage and overflow, and the top cover with the small hole also frequently experiences pressure buildup. If refilling is not timely, the heating coil can dry-burn, damaging the atomizer core. Therefore, electronic cigarette atomizers with refill bottles have emerged on the market. Since the refill bottle stores a large amount of e-liquid, the user can quickly transfer e-liquid from the refill bottle to the reservoir when the e-liquid level is low.

[0003] However, such products all have the disadvantage of inconvenient e-liquid filling operation. For example, some large-capacity e-cigarettes with e-liquid bottles are made to dispense e-liquid by the user manually squeezing the bottle. This requires the user to constantly observe and monitor the amount of e-liquid in the reservoir in order to replenish the e-liquid in time. The amount of e-liquid to be replenished depends on the user's manual operation, which is greatly affected by subjective factors and is prone to leakage. Utility Model Content

[0004] Therefore, it is necessary to address the problems of inconvenient refilling and easy leakage of e-liquid in existing electronic atomizing devices, and to provide an atomizer and an electronic atomizing device including the atomizer, so as to achieve the purpose of automatic refilling and ensuring no leakage during refilling.

[0005] According to one aspect of this application, an atomizer is provided that can be detachably used with an external liquid reservoir, the atomizer comprising:

[0006] A first housing is provided with a liquid guide tube, one end of which extends into the first housing and the other end is exposed outside the first housing and used to connect to the external liquid storage tank.

[0007] A liquid storage assembly is disposed within the first housing, and the liquid storage assembly has a first liquid storage chamber;

[0008] An atomizing component is disposed within the liquid storage component, and the atomizing component has an atomizing chamber that communicates with the first liquid storage chamber;

[0009] An injection pump is disposed inside the first housing. The injection pump has an inlet and an outlet. The inlet is connected to one end of the liquid guide tube that extends into the first housing through a first delivery tube. The outlet is connected to the first storage chamber through a second delivery tube.

[0010] In one embodiment, the first liquid storage chamber is provided with a liquid storage component, the liquid storage component encloses the atomizing component, and one end of the second infusion tube is inserted into the liquid storage component.

[0011] In one embodiment, the injection pump is any one of a peristaltic pump, a piezoelectric pump, a diaphragm pump, or a screw pump.

[0012] In one embodiment, the liquid storage assembly includes a first bracket and a seal connected to the first bracket. One end of the first bracket has an opening, and the seal seals the opening and surrounds the first bracket to form the first liquid storage cavity. The first bracket also surrounds the inner wall of the first housing to form a first mounting position isolated from the first liquid storage cavity, and the liquid injection pump is disposed in the first mounting position.

[0013] In one embodiment, the atomizing component includes an atomizing tube and an atomizing core. The atomizing tube has a main air passage extending through its axially opposite ends. The atomizing core is disposed within the main air passage. The atomizing chamber is enclosed by the atomizing core. The first housing has an air inlet and an air outlet, which are interconnected through the main air passage.

[0014] In one embodiment, the first housing is further provided with a second support, which is connected to the liquid storage component. The second support has an airflow channel extending through its opposite ends. One end of the airflow channel is connected to the air inlet, and the other end is connected to the main air passage. The airflow channel is offset from the main air passage in its axial direction.

[0015] In one embodiment, the second support and the liquid storage assembly form a liquid suction chamber between the main air passage and the airflow passage, which connects the main air passage and the airflow passage, and the liquid suction chamber is provided with a liquid suction element.

[0016] In one embodiment, the second bracket, the liquid storage assembly, and the inner wall of the first housing together form a second mounting position isolated from the first liquid storage chamber. The second mounting position is provided with a control board electrically connected to the injection pump. The control board is used to control the injection pump to draw atomized liquid from the external liquid storage chamber and supply liquid to the first liquid storage chamber based on the remaining amount of atomized liquid in the first liquid storage chamber.

[0017] According to another aspect of this application, an electronic atomizing device is provided, including an external liquid reservoir and an atomizer as described in any of the above embodiments, wherein the external liquid reservoir is detachably connected to the atomizer, and when the external liquid reservoir is connected to the atomizer, one end of the liquid guide tube on the atomizer extends into the external liquid reservoir.

[0018] In one embodiment, the external reservoir has an inner cavity, within which is provided a spacer made of soft material. The spacer is connected to the cavity wall of the inner cavity to divide the inner cavity into a second reservoir and a pressure balancing cavity that are isolated from each other. One end of the liquid guide tube extends into the second reservoir. The spacer is configured to undergo recoverable deformation when the atomizer's injection pump draws atomizing liquid from the external reservoir, thereby reducing the volume of the second reservoir and increasing the volume of the pressure balancing cavity.

[0019] The aforementioned atomizer and electronic atomizing device including the atomizer, on the one hand, by setting an external liquid storage tank that is detachably connected to the atomizer, allow the atomizer and the external liquid storage tank to be transported and shipped separately. Therefore, during transportation, the atomized liquid in the external liquid storage tank can be well sealed individually, thereby solving the leakage problem that is prone to occur during the transportation of existing electronic atomizing devices. Moreover, because the external liquid storage tank can be transported separately and is well sealed, liquid atomized liquid can be directly stored in the external liquid storage tank, thereby improving the utilization rate of the atomized liquid. At the same time, external liquid storage tanks containing different flavored atomized liquids can be replaced and used with the atomizer, which can effectively enhance the vaping experience.

[0020] On the other hand, by setting a liquid injection pump in the atomizer, the inlet of the liquid injection pump is connected to a liquid guide pipe on the first housing through a first liquid delivery pipe, and the outlet of the liquid injection pump is connected to the first liquid storage chamber of the atomizer through a second liquid delivery pipe. This allows the liquid injection pump to automatically inject atomized liquid into the first liquid storage chamber according to the amount of atomized liquid remaining in the first liquid storage chamber when the atomizer is connected to an external liquid storage chamber. As a result, the atomizer provided by this application has a simple structure, is easy to operate, and is not prone to oil leakage during the liquid injection process. It changes the traditional manual liquid injection method and avoids the situation of burning taste caused by untimely manual liquid injection, thus meeting the user's vaping taste requirements.

[0036] One embodiment of this application provides an atomizer and an electronic atomizing device including the atomizer. The electronic atomizing device is used to heat the atomizing liquid stored inside itself to form an aerosol for inhalation by a user.

[0037] The following description uses an electronic cigarette as an example of an electronic atomizing device and e-liquid as an example of an e-liquid to illustrate the structure of the electronic atomizing device in this application. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the electronic atomizing device of this application is not limited to an electronic cigarette, but can also be any other electronic atomizing device capable of atomizing e-liquid into an aerosol, which is not limited here.

[0038] See Figures 1 to 3 , Figure 1 and Figure 2 This paper shows a schematic diagram of the appearance of the electronic atomizing device 10 in one embodiment of the present application. Figure 3 An exploded view of the electronic atomizing device 10 in this embodiment is shown. An embodiment of the electronic atomizing device 10 provided in this application includes an atomizer 100 and an external liquid storage tank 200. The atomizer 100 has an air inlet 101 and an air outlet 102 that are interconnected. The external liquid storage tank 200 stores atomizing liquid. The atomizer 100 and the external liquid storage tank 200 are detachably connected to each other so that the atomizer 100 can be used in conjunction with the external liquid storage tank 200. When the atomizer 100 is used in conjunction with the external liquid storage tank 200, the atomizing liquid in the external liquid storage tank 200 can be drawn into the atomizer 100. The atomizer 100 can heat the atomizing liquid, causing it to atomize and generate an aerosol. When the user inhales, outside air enters the atomizer 100 through the air inlet 101, mixes with the aerosol, and is inhaled by the user through the air outlet 102.

[0039] Specifically, in one embodiment, such as Figure 4 As shown, the atomizer 100 includes a first housing 110, a liquid storage assembly 120, an atomizing assembly 130, a liquid injection pump 140, and a power supply assembly 150; the liquid storage assembly 120, the atomizing assembly 130, the liquid injection pump 140, and the power supply assembly 150 are all disposed within the first housing 110, and an air inlet 101 and an air outlet 102 are formed on the first housing 110, and are combined with Figure 3As shown, the first housing 110 is provided with a liquid guide tube 160, one end of which extends into the first housing 110, and the other end extends out of the first housing 110 and is used to connect to the external liquid storage tank 200; the liquid storage assembly 120 has a first liquid storage chamber 120a; the atomizing assembly 130 is disposed in the liquid storage assembly 120, and the atomizing assembly 130 has an atomizing chamber 132a communicating with the first liquid storage chamber 120a; as shown Figure 5 and Figure 6 As shown, the injection pump 140 has an inlet 141 and an outlet 142. The inlet 141 is connected to one end of the guide tube 160 that extends into the first housing 110 through the first delivery tube 170. The outlet 142 is connected to the first storage chamber 120a through the second delivery tube 180. The power supply component 150 is connected to the storage component 120 and electrically connected to the atomizing component 130 and the injection pump 140.

[0040] In terms of the function of the above-mentioned components, the power supply component 150 is used to supply power to the injection pump 140 and the atomizing component 130, so that the injection pump 140 can automatically draw atomizing liquid from the external storage tank 200. The atomizing liquid can be drawn into the injection pump 140 through the first infusion pipe 170, and then the drawn atomizing liquid can be automatically transported to the first storage chamber 120a through the second infusion pipe 180. Thus, the first storage chamber 120a always stores atomizing liquid, thereby enabling the atomizing component 130 to atomize the atomizing liquid stored in the first storage chamber 120a into an aerosol in the atomizing chamber 132a.

[0041] It is evident that, compared to the traditional manual injection method, the above-mentioned automatic injection method using injection pump 140 is more convenient to operate, can perform quantitative automatic injection, reduces the influence of subjective factors during injection, and is less prone to leakage during the injection process.

[0042] For a better option, please continue reading. Figure 4 Based on the above embodiment, a liquid storage component 121 made of fiber cotton is provided in the first liquid storage chamber 120a. The liquid storage component 121 encloses the atomizing component 130, and one end of the second infusion tube 180 is inserted into the liquid storage component 121. The purpose of providing the liquid storage component 121 is that it has the functions of locking and guiding liquid. Therefore, the atomizing liquid in the first liquid storage chamber 120a can be immersed in the liquid storage component 121, preventing the atomizing liquid from flowing arbitrarily. This can prevent the atomizing liquid from leaking out of the first liquid storage chamber 120a, and can also ensure that the electronic atomizing device 10 has a sufficient supply of atomizing liquid during use, avoiding the phenomenon of dry burning and scorching of the coil.

[0043] More specifically, the atomizing assembly 130 includes an atomizing tube 131 and an atomizing core 132. The atomizing tube 131 has a main air passage 131a extending through its two opposite ends along its axial direction. The atomizing core 132 is disposed within the main air passage 131a, and the atomizing core 132 is enclosed by the atomizing core 132. The air inlet 101 and the air outlet 102 are interconnected through the main air passage 131a. The atomizing tube 131 also has a liquid inlet hole (not shown in the figure), and the first liquid storage chamber 120a is connected to the atomizing core 132 through the liquid inlet hole. The liquid storage assembly 120 includes a first support 122 and a sealing member 123 connected to the first support 122. One end of the first support 122 has an opening, and the sealing member 123 seals the opening and encloses the first support 122 to form the first liquid storage chamber 120a. Preferably, the first bracket 122 is made of plastic material and serves to support the various components in the atomizer 100. The seal 123 is made of silicone material and serves to seal the first liquid storage chamber 120a to prevent leakage of the atomized liquid in the first liquid storage chamber 120a. To facilitate the installation of the injection pump 140, the first bracket 122 and the inner wall of the first housing 110 also form a first mounting position 120b, which is isolated from the first liquid storage chamber 120a. The injection pump 140 is disposed in the first mounting position 120b.

[0044] Furthermore, the atomizing core 132 includes a liquid guiding component (not shown in the figure) and a heating component (not shown in the figure). When the injection pump 140 pumps the extracted atomized liquid into the first liquid storage chamber 120a, the atomized liquid can be guided by the liquid storage component 121 into the liquid guiding component of the atomizing core 132. The heating component generates heat to atomize the atomized liquid in the liquid guiding component into an aerosol. This aerosol mixes with the outside air entering the atomizing chamber 132a from the air inlet 101 and is then inhaled by the user through the main air passage 131a and the air outlet 102. Preferably, the air outlet 102 is coaxially arranged with the main air passage 131a and the atomizing chamber 132a, so that the airflow and atomized gel can flow smoothly and be fully inhaled into the user's mouth, improving the user's inhalation experience.

[0045] It is understandable that the structure of the atomizing component 130 is not limited to this, and can be any existing structure. For details, please refer to the existing technology, which will not be elaborated here.

[0046] In some embodiments, the injection pump 140 is a peristaltic pump. Specifically, a peristaltic pump is a fluid delivery device based on the principle of volume change. It has an elastic hose and rollers inside. One end of the elastic hose is an inlet 141, and the other end is an outlet 142. The rollers roll on the elastic hose to alternately squeeze and release it. When the rollers squeeze the hose, the hose is compressed, reducing its cross-sectional area and forcing the atomized liquid inside the hose to move forward. After the rollers rotate, the hose returns to its original shape, forming a negative pressure area that attracts more atomized liquid into the rear of the hose, thus achieving continuous quantitative delivery of the atomized liquid using a simple mechanical principle. Moreover, when the rollers roll close to the outlet 142, the squeezing force on the elastic hose is greater, which can cut off the delivery channel formed by the elastic hose. Therefore, the inner cavity 201 of the external storage tank 200 is isolated from the first oil storage chamber, preventing the atomized liquid from leaking from the external storage tank 200 into the first oil storage chamber when the injection pump 140 is not working.

[0047] As an alternative implementation, the injection pump 140 can also be a piezoelectric pump, which operates by utilizing the inverse piezoelectric effect of a piezoelectric material (such as lead zirconate titanate). When an alternating electric field is applied to both ends of the piezoelectric material, the material undergoes mechanical deformation, such as radial compression or bending. This causes a periodic change in the volume of the pump chamber, thereby generating a pressure difference that draws in or discharges the atomized liquid.

[0048] Of course, the injection pump 140 can also be a diaphragm pump or a screw pump. The diaphragm pump mainly changes the fluid flow rate by receiving the control signal output by the regulating control unit and using power operation; while the screw pump is mainly driven by the prime mover through the speed change device to drive the screw pump shaft so that the liquid enters the blades, rises along the spiral flow channel, and flows out. The more specific working principles of the two can be referred to the existing technology, which will not be elaborated here.

[0049] See Figure 4In one embodiment, the power supply component 150 is connected below the liquid storage component 120 and includes a second bracket 151, a power supply 152, and a control board 153. The second bracket 151 is connected to the seal 123 of the liquid storage component 120. Similar to the first bracket 122 in the liquid storage component 120, the second bracket 151 also serves a supporting function. Specifically, the second bracket 151, together with the inner wall of the liquid storage component 120 and the first housing 110, forms a second mounting position 15 that is isolated from the first liquid storage cavity 120a. 1a. The control board 153 and the power supply 152 are installed in the second mounting position 151a. The power supply 152 is electrically connected to the atomizing core 132 and the liquid injection pump 140, and the control board 153 is electrically connected to the power supply 152. The power supply 152 is used to supply power to the atomizing core 132 and the liquid injection pump 140, and the control board 153 is used to control the power supply 152 to be turned on and off. It can also control the liquid injection pump 140 to draw atomizing liquid from the external liquid storage tank 200 and supply liquid to the first liquid storage tank 120a based on the remaining amount of atomizing liquid in the first liquid storage chamber 120a.

[0050] Thus, under the control of the control board 153, the injection pump 140 can intelligently and automatically extract atomized liquid from the external storage tank 200 and inject it into the first storage tank 120a in a quantitative manner based on the remaining amount of atomized liquid in the first storage chamber 120a. For example, when the atomized liquid in the first storage chamber decreases to 3ml, the control board 153 can control the injection pump 140 to automatically inject 26mg of atomized liquid into the first storage chamber 120a every two or three puffs by the user, according to its built-in control algorithm. This cycle continues until the atomized liquid in the external storage tank 200 is exhausted, thereby automatically completing the extraction and replenishment of atomized liquid. This eliminates the need for the user to constantly observe and monitor the remaining amount of atomized liquid in the first storage chamber 120a, making it more convenient for the user and ensuring that the atomized liquid is fully atomized, thus improving the atomization experience.

[0051] For a better option, see [link / reference] Figure 7 To gather the outside air entering the atomizer 100 through the air inlet 101, allowing more air to enter the atomization chamber 132a, the second support 151 has an airflow channel 151b extending through its opposite ends. One end of the airflow channel 151b connects to the air inlet 101, and the other end connects to the main air passage 131a. This allows outside air entering from the air inlet 101 to pass through the airflow channel 151b into the main air passage 131a, and then into the atomization chamber 132a to mix with the aerosol. More preferably, the airflow channel 151b is offset from the main air passage 131a in its axial direction, so that after the electronic atomizing device 10 is stopped, the condensate formed by the pre-cooling and condensation of the aerosol in the atomization chamber 132a will not flow downwards along the airflow channel 151b and leak out from the air inlet 101.

[0052] For better information, please continue reading. Figure 7 The second support 151 and the first support 122 of the liquid storage assembly 120 also form a liquid suction chamber 151c between the main air channel 131a and the air flow channel 151b, which connects the main air channel 131a and the air flow channel 151b. The liquid suction chamber 151c is provided with a liquid suction element 154, which can collect the condensate dripping from the atomizing chamber 132a, thereby further preventing the condensate from leaking out.

[0053] It should be noted that the atomizer 100 may also be equipped without a power supply component 150, and can be powered and controlled by connecting to an external power source. This is not a limitation.

[0054] Regarding the connection method between the external liquid storage tank 200 and the atomizer 100 Figure 3 In the embodiments described, magnetic components 300 are provided on both the side of the external liquid storage tank 200 facing the atomizer 100 and the side of the atomizer 100 facing the external liquid storage tank 200, so that the two can be detachably connected by magnetic attraction. Of course, the two can also be detachably connected to each other by snap-fit, which is not limited here.

[0055] It is easy to see that by detachably connecting the atomizer 100 and the external liquid storage tank via magnetic or snap-fit ​​connection, the atomizer 100 and the external liquid storage tank 200 can be transported and shipped separately. During transportation, the atomized liquid in the external liquid storage tank 200 can be well sealed individually, thus solving the leakage problem that easily occurs during transportation of existing electronic atomizing devices 10. Moreover, because the external liquid storage tank 200 can be transported separately and is well sealed, liquid atomized liquid can be directly stored in the external liquid storage tank 200, thereby improving the utilization rate of the atomized liquid. At the same time, the external liquid storage tank 200 containing different flavored atomized liquids can be replaced and used with the atomizer 100, which can effectively improve the vaping experience.

[0056] Furthermore, regarding the internal structure of the external liquid storage tank 200, in one embodiment, as follows: Figure 4 As shown, the external liquid storage chamber 200 has an inner cavity 201. The inner cavity 201 is provided with an isolation member 202 made of a soft material (such as silicone). The isolation member 202 is connected to the cavity wall of the inner cavity 201 to divide the inner cavity 201 into a second liquid storage chamber 201a and a pressure balance chamber 201b that are isolated from each other. The atomizing liquid is stored in the second liquid storage chamber 201a. One end of the liquid guide tube 160 extends into the second liquid storage chamber 201a. The isolation member 202 is configured to produce a slight, recoverable deformation when the injection pump 140 draws the atomizing liquid to reduce the volume of the second liquid storage chamber 201a and increase the volume of the pressure balance chamber 201b.

[0057] As can be seen, through the above settings, the pressure balance point can be achieved by the elastic expansion and contraction of the isolator 202, so that the internal pressure of the external liquid storage chamber 200 can always be kept stable. Practice has proven that the atomizing liquid in the sealed second liquid storage chamber 201a can be extracted with very little force, thereby enabling the injection pump 140 to maintain stable atomizing liquid transmission during the transmission process, effectively avoiding the phenomenon of dry burning and burnt smell caused by poor atomizing liquid transmission in the atomizing core 132.

[0058] Therefore, the atomizer 100 and electronic atomizing device 10 provided in this application have a simple structure and are easy to operate. Different flavored atomizing liquids can be replaced at any time, which solves the problem of oil leakage during storage, transportation and vaping of the disposable large-capacity electronic atomizing device 10. It also changes the traditional manual liquid filling method.
