Description

Technical Field

[0001] The invention belongs to the field of electronic atomizers, and in particular relates to an atomization device. Background Art

[0002] The battery rod in the atomizer device supplies power to the atomizer, which includes a heating element and an oil guide element connected to each other. The oil guide element absorbs the atomized liquid stored in the atomizer, and the heating element heats the atomized liquid. The heated atomized liquid mixes with the air to form an aerosol for the user to inhale. The high-temperature aerosol is prone to condensation when it is cooled, and the condensed liquid will contain a small amount of atomized liquid. The condensed liquid containing the atomized liquid affects the taste during the user's inhalation process. At the same time, the condensed liquid flows back into the atomizer, affecting the atomization effect of the atomizer device.

[0003] With the development of ESG at home and abroad, the electronic atomization industry has paid more and more attention to environmental protection. In the existing cartridge-changing atomization device, after the e-liquid is exhausted, the atomizer is discarded and the battery rod is reused. In order to reduce the consumption of resources and the loss to the environment, as many parts as possible should be reused. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an atomization device, aiming to provide a new type of detachable atomization device, so that the electronic atomization device is more in line with the development direction of environmental protection.

[0009] In some embodiments of the present invention, a guiding body is disposed in the atomization space, and the guiding body divides the atomization space into two branch flow channels connecting the air flow channel and the air holes.

[0010] In some embodiments of the present invention, a seal is further provided at the bottom of the atomization space for sealing the connecting gap between the battery rod and the atomizer. The seal is provided with the air hole for communicating with the atmosphere. Two electrodes are further provided in the battery rod. The two electrodes are passed through the seal and are electrically connected one by one to the electrode connecting parts of the heating element.

[0011] In some embodiments of the present invention, the flow guide and the sealing element are integrally formed.

[0012] In some embodiments of the present invention, the flow guide includes a base and a partition connected to the base, the base is disposed between the two air holes, and the partition is protruded corresponding to the center position of the projection of the air flow channel.

[0014] In some embodiments of the present invention, a plug-in groove is formed on the top of the battery rod, and a blocking portion is convexly provided on the outer surface of the atomizer. When the atomizer and the battery rod are plugged in, the limiting portion abuts and cooperates with the top surface of the peripheral wall of the plug-in cavity to form the extreme position of the plug-in stroke.

[0015] Compared with the prior art, the atomizing device of the present invention has the following beneficial effects:

[0016] The present invention proposes an atomization device, including an atomizer with an oil storage body built in and a battery rod detachably connected to the atomizer; wherein, an airflow channel penetrating both ends and an oil guide body connected to the oil storage body are formed in the atomizer, and the oil guide body is installed at the bottom end of the atomizer; the battery rod is recessed to form a cavity, and a heating element is arranged in the cavity.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] Please refer to Figures 1 to 3 The present invention provides an atomization device 100, characterized in that it includes an atomizer 10 with an oil storage body 102 built in and a battery rod 11 detachably connected to the atomizer 10; wherein,

[0027] The atomizer 10 is formed with an air flow channel 101 passing through both ends and an oil guide body 103 connected to the oil storage body 102. The oil guide body 103 is installed at the bottom end of the atomizer 10 and is arranged around the air flow channel 101.

[0028] The battery rod 11 is recessed to form a cavity, and a heating element 111 is arranged in the cavity. When the atomizer 10 and the battery rod 11 are connected, the heating element 111 is connected to the side of the oil guide body 103 away from the oil storage body 102, and forms an atomization space with at least a part of the cavity. The atomization space is provided with an air hole 1131 connected to the atmosphere; when the battery rod 11 and the atomizer 10 are disassembled, the heating element 111 is separated from the oil guide body 103 and is located in the cavity of the battery rod 11 to prevent the heating element 111 from overheating and scalding the user when the atomizer 10 is replaced. The heating element 111 and the electrode column can be reused when changing the cartridge, and part or all of the atomization space is formed in the battery rod 11, which can save space for the atomizer 10, making the disposable atomizer 10 as small as possible and using fewer consumables, which is in line with the direction of ESG.

[0029] In this embodiment, the heating element 111 is a planar heating element 111, the plane where the heating element 111 is located is kept flush with the plane where the port of the airflow channel 101 is located, the heating element 111 includes at least two heating units 1111 arranged along the radial direction of the battery rod 11, and each heating unit 1111 is arranged on both sides of the port of the airflow channel 101. The mixed airflow formed by the heated aerosol and the air mixed has only one corner in the flow path from the heating unit to the airflow channel, and there is no other structure in the airflow channel, which minimizes the possibility of condensation. Preferably, in this embodiment, the heating element 111 includes two heating units 1111 connected in series.

[0030] The oil storage body 102 in the atomizing device 100 contains atomized liquid, or is connected to the oil tank contained in the atomizer 10. The oil guide body 103 is used to transmit the atomized liquid in the oil storage body 102. The heating body 111 is connected to the oil guide body 103 to heat the atomized liquid to generate aerosol. The aerosol is mixed with the air inhaled from the outside to form a mixed airflow for the user to inhale. In this embodiment, the atomizer 10 has a shell, and a pipe with two ends passing through is formed in the shell, that is, an air flow channel 101. The shell is provided with a placement cavity for placing an oil storage body 102 around the side of the air flow channel 101. The oil storage body 102 contains atomized liquid. The oil storage body 102 can be a cylinder with a circular cross section. The oil guide body 103 is arranged at the bottom end of the atomizer 10. When the atomizer 10 and the battery rod 11 are connected, the oil guide body 103 at the bottom end of the atomizer 10 is connected to the heating body 111 in the cavity of the battery rod 11, so as to realize the function of heating the atomized liquid in the oil guide body 103. The oil guide body 103 is arranged at the bottom end of the atomizer 10, which is conducive to the atomized liquid flowing into the bottom of the atomizer 10, and the utilization rate of the atomized liquid is maximized, further improving the atomization effect. At the same time, the heating element 111 is preferably in a planar shape. The planar heating element 111 is clamped up and down, and the force is relatively uniform, so that it fits the oil guide body 103 better, ensures the uniformity of the oil guide, and further improves the consistency of the atomization efficiency and the taste of the inhaled mixed airflow. When the atomized liquid enters the oil guide body 103, it is heated by the heating element 111, and the aerosol generated by the heating is mixed with the air. The two heating units 1111 of the heating element 111 are arranged close to the port of the airflow channel 101. It is preferred that the plane where the heating element is located is kept flush with the plane where the port of the airflow channel is located, so as to reduce the collision with the wall during the aerosol transmission process and reduce the generation of condensed liquid.

[0031] In this embodiment, please refer to Figure 2 The heating element 111 includes two heating units 1111. The heating unit 1111 can be a metal wire. The movement of free electrons inside the metal material improves the efficiency of heat transfer. The metal wires are interwoven in a grid shape. The grid shape includes but is not limited to circular, diamond or square shapes. The mesh metal heating unit has both rigidity and toughness, which can further ensure the contact uniformity between the oil guide body 103 and the heating element. Of course, the metal wire can be in a straight line, a wavy line or a broken line shape. It is preferably a wavy line or a broken line shape. Compared with the straight line design, the length of the heating unit 1111 is increased, and the heating efficiency of the heating unit 1111 is further improved. It can be set according to actual needs.

[0032] The heating unit 1111 can be set to two or more, and the metal wires of the multiple heating units 1111 can be set to different lengths. Metal wires of different lengths have different resistance values ​​and therefore have different heating powers. By adjusting the electrical connection between the battery rod 11 and different heating units 1111, the atomization amount of the atomizer 10 can be adjusted to meet the needs of different users. In other embodiments, the heating unit 1111 can also be set to the same length, but the metal materials used in the multiple heating units 1111 are different, and different metal materials have different resistivities. Therefore, the resistance between the multiple heating units 1111 is different, and the amount of atomization generated is also different. It can be understood that the bending forms between the multiple heating units 1111 are different, and they also have different resistances, and the effects are the same, which will not be expanded here.

[0033] Furthermore, a seal 113 is provided at the bottom of the atomization space for sealing the connection gap between the battery rod 11 and the atomizer 10. The seal 113 is provided with an air hole 1131 for communicating with the atmosphere. Two electrodes 112 are also provided in the battery rod 11. The two electrodes 112 are passed through the seal 113 and are electrically connected to the electrode connection parts of the heating element 111. In the existing cartridge-changing atomizer, the heating element and the electrode are discarded together with the atomizer, resulting in unnecessary waste. The heating element and the electrode of this embodiment can be reused.

[0034] The battery rod 11 also includes a built-in battery, which can be a dry cell or a rechargeable battery. In the form of a battery, the atomizing device 100 can store electrical energy inside, and the user can move the atomizing device 100 to use it, thereby improving the portability of the atomizing device 100. The battery provides power to the heating element 111 through the electrode 112. One end of each electrode 112 is electrically connected to the battery, and the other end extends from the sealing member 113 to be exposed in the cavity of the battery rod 11 and is electrically connected to a heating unit 1111. The connection form can be a fixed form such as welding or plugging.

[0035] The seal 113 can be made of an airtight material such as rubber or silicone, and is sealed between the gap between the atomizer 10 and the battery rod 11. The aerosol in the airflow channel 101 is not easy to escape from the gap, and the overall airtightness of the atomizer 100 is enhanced. The seal 113 also has a supporting and positioning function for the two heating units 1111. In other embodiments, a contact plane may be provided on the peripheral wall of the seal 113 to support the heating element 111 and provide a relatively uniform clamping force for the heating element 1111 together with the atomizer. The position of the electrode 112 is fixed, and the positions of the two heating units 1111 connected to the electrode 112 are also fixed. During the assembly process of the atomizer 10 and the battery rod 11, the two heating units 1111 can be fitted to the position of the oil guide body 103, thereby improving the heating effect of the atomized liquid and the consistency of the aerosol taste. In some embodiments, the oil storage body 102 may be in the form of oil storage cotton or an enclosed oil tank, etc., for storing the atomized liquid, and the oil guide body 103 may be a flexible material or a porous ceramic material, or other materials with adsorption, which can precipitate the atomized liquid from the oil storage body 102, and guide the atomized liquid from the oil storage body 102 to the heating body 111 for heating. In this embodiment, the oil guide body 103 is a flexible flat plate-shaped oil guide cotton, which can ensure that when the atomizer 10 is plugged into the battery rod 11, compared with a hard oil guide body such as porous ceramics, the heating body 111 and the flat plate-shaped flexible oil guide body 103 fit more fully, ensuring the uniformity of the oil guide efficiency and the consistency of the taste.

[0036] For more details, please refer to Figure 1 The seal 113 is provided with two air holes 1131 connected to the air flow channel 101. The air flow channel 101 is connected to the outside atmosphere through the two air holes 1131, and the air entering the air flow channel 101 is mixed with the aerosol to form a mixed air flow. The top of the atomizer 10 can be a suction nozzle, which is used by the user. The suction nozzle connects the air flow channel 101 and the two air holes 1131, forming a complete air flow loop from the outside atmosphere into the battery rod 11, through the air holes 1131 to the air flow channel 101, and finally to the suction nozzle. When the user takes a puff, the air flow enters from the outside atmosphere and mixes with the aerosol and then flows to the suction nozzle. It is preferred that the two air holes are symmetrically arranged to facilitate the transmission of the aerosol.

[0037] In this embodiment, when the atomizer 10 and the battery rod 11 are assembled and connected, an atomization space connected to the airflow channel 101 is formed inside, and one side of the heating element 111 is connected to the oil guide body 103, and the other side is exposed in the atomization space. The atomizer 10 and the battery rod 11 are detachably connected, and the detachable connection can be in the form of plug-in, snap-on, etc. The atomizer 10 and the battery rod 11 are concavely provided with cavities, and the two cavities enclose the atomization space. The heating element 111 in the atomization space heats the atomized liquid of the oil guide body 103, and the aerosol generated by the heating is mixed with the air to form a mixed airflow. The detachable atomizer 10 and battery rod 11 are advantageous for replacing the atomizer 10 after the atomizing liquid in the atomizer 10 is used up. Meanwhile, after the atomizing device 100 is used for a long time, condensation liquid is likely to remain in the atomizing space, which affects the atomizing effect. If the atomizing device 100 needs to be cleaned, it can be achieved by disassembling the atomizer 10 and the battery rod 11, which facilitates the maintenance of the atomizing device 100.

[0038] At the same time, in the related art, when the atomizer 10 is replaced by the atomizer 10, the atomizer 10 needs to be directly replaced. The atomizer 10 does not include the heating element 111, so the cost control of the atomizer 10 can be achieved. The heating element 111 is reusable, and the connection between the heating element 111 and the electrode 112 is more stable, which is conducive to improving the atomization effect.

[0039] Furthermore, a guide body 114 is provided in the atomization space, and the guide body 114 divides the atomization space into two branch channels 1132 connecting the airflow channel 101 and the air hole 1131, and the branch channels 1132 can be completely isolated or partially isolated. The aerosol generated by the heating unit 1111 is mixed with air in the branch channel 1132 to form a mixed airflow, and the branch channel 1132 effectively shortens the flow path of the aerosol. The aerosol can directly enter the airflow channel 101 through the guidance of the branch channel 1132, avoiding the formation of turbulence at the confluence of the airflows on both sides at the lower port of the airflow channel 101, thereby forming a large amount of condensate.

[0040] Preferably, the flow guide 114 and the sealing member 113 are integrally formed. The flow guide 114 and the sealing member 113 may also be detachably connected.

[0041] In this embodiment, the flow guide 114 includes a base 1141 and a partition 1142 connected to the base 1141. The base 1141 is arranged between the two air holes 1131, and the partition 1142 is protruded corresponding to the center position of the projection of the air flow channel 101. The flow guide 114 can be a polymer such as silicone, rubber or plastic, which has strong corrosion resistance and stability, and is not easy to change for long-term contact with the gas containing the atomized liquid. The base 1141 of the flow guide 114 is in contact with the sealing member 113, which can be in the form of fixed connection, integral molding or detachable connection. The plane area of ​​the base 1141 is larger than the partition 1142 arranged on the base 1141. The partition 1142 and the base 1141 can also be in the form of fixed connection, integral molding or detachable connection, that is, the air flows from the air hole 1131 on the sealing member 113 to the channel between the sealing member 113 and the base 1141, and the mixed airflow goes along the edge connected to the base 1141 and the partition 1142 to the air flow channel 101. Therefore, the partition 1142 is arranged corresponding to the center position of the airflow channel 101 to ensure the flow path of the aerosol into the airflow channel 101. The partition 1142 can extend into the airflow channel 101 or close to the port of the airflow channel 101, thereby guiding the aerosol into the airflow channel 101.

[0042] More specifically, the length of the base 1141 is greater than or equal to half the length of the heating element 111 (e.g. Figure 2 As shown, the length of the heating element of the present invention is the length of the heating unit and the connecting part between the heating units, excluding the electrode connecting part), the length of the heating element 111 includes the length of the connecting part between the two heating units 1111 and the base 1141. If the length is greater than or equal to half of the length of the heating unit 1111 and the connecting part, the corresponding area of ​​the base 1141 and the heating unit 1111 is larger, so that the external air is guided to the outer half of the heating unit through the air hole 1131, avoiding that all the air is introduced into the inner half of the heating unit, forming a dead angle in the space corresponding to the outer half, and a large amount of aerosol cannot be taken away, resulting in a larger amount of condensate; most of the aerosol generated near the heating unit 1111 directly enters the airflow channel 1132 formed by the guide body 114, and the aerosol is guided into the airflow channel 101 by the airflow channel 1132, so that the external air can better carry the aerosol away. At the same time, the larger length of the base 1141 effectively prevents the aerosol from accumulating at the bottom of the atomization space, and the user can inhale more aerosol.

[0043] In this embodiment, please refer to Figure 2 and Figure 3, an avoidance hole 1112 connected to the airflow channel 101 is provided between each heating unit 1111 of the heating element 111. The area of ​​the avoidance hole 1112 may be the same as the cross-sectional area of ​​the airflow channel 101, so that the airflow channel 101 is connected to the atomization space, and the guide body 114 disposed between the seal 113 and the heating element 111 cooperates with the avoidance hole 1112, and the partition 1142 of the guide body 114 extends into the airflow channel 101 through the avoidance hole 1112. In other embodiments, the two heating units 1111 of the heating element 111 may be independent of each other, and the partition 1142 may extend into the airflow channel 101 through the avoidance hole 1112 between the two heating units 1111, so as to guide the flow direction of the aerosol.

[0044] More specifically, the top of the battery rod 11 is concavely provided with a plug-in slot 115, and the outer surface of the atomizer 10 is convexly provided with a blocking portion 104. When the atomizer 10 and the battery rod 11 are plugged in, the limiting portion 104 abuts against the top surface of the peripheral wall of the plug-in slot 115 to form the limit position of the plug-in stroke. During use, the plugging of the atomizer 10 and the battery rod 11 forms an atomization space between the bottom end of the atomizer 10 and the top end of the battery rod 11, and the heating element 111 of the battery rod 11 abuts against the oil guide body 103 of the atomizer 10 to heat the atomized liquid. After the atomizer liquid in the oil storage body 102 in the atomizer 10 is heated and consumed, the atomizer 10 needs to be replaced. This can be done by disconnecting the atomizer 10 from the plug-in slot 114. The outer diameter of the atomizer 10 can be the same as the inner diameter of the plug-in slot 115. The atomizer 10 can be replaced without replacing the battery rod 11, and the atomizer liquid can be replenished conveniently and quickly to meet the user's needs for long-term use.

[0045] During the process of disassembly and insertion, the blocking portion 104 of the atomizer 10 is more protruding relative to the outer surface of the atomizer 10, which can effectively prevent the atomizer 10 and the battery rod from overfitting and causing the atomization space to be reduced, and realize the precise positioning of the installation of the atomizer 10 and the battery rod 11. The blocking portion 104 is integrally formed with the outer surface of the atomizer 10, and the blocking portion 104 can be set as a plane in the direction facing the battery rod 11, and the top surface of the peripheral wall of the plug-in slot 115 facing the atomizer 10 can also be set as a plane. The two planes fit tightly, which improves the airtightness between the atomizer 10 and the battery rod 11, and effectively prevents the leakage of the internal gas of the atomization device 100. In one embodiment, the outer surface of the atomizer 10 can be sleeved with a sealing ring, and the blocking portion 104 and the top surface of the peripheral wall of the plug-in slot 115 clamp the two sides of the sealing ring, and the sealing ring further enhances the airtightness of the plug-in fit between the atomizer 10 and the battery rod 11.

[0046] Furthermore, in order to enhance the connection stability between the atomizer 10 and the battery rod 11, a buckle is convexly provided on the outer peripheral surface of the atomizer 10, and a slot that matches the buckle is provided on the inner wall of the plug-in portion 115 of the battery rod 11. When the atomizer 10 and the battery rod 11 are plugged in, the buckle and the slot are plugged in, thereby limiting the relative movement of the atomizer 10 and the battery rod 11. The buckle is provided with an introduction surface, and the angle between the introduction surface and the outer peripheral surface of the atomizer 10 is small, which has a smooth transition effect. The user can achieve the plug-in fixation and separation of the atomizer 10 and the battery rod 11 by applying stress, which is convenient for disassembly and also plays a role in preventing accidental touch.

[0047] In this embodiment, a control mainboard and a charging compartment for placing batteries are provided inside the battery rod 11. A charging port is provided on the control mainboard for supplying power to the battery. The charging port is exposed at the bottom of the battery rod 11. A silicone member may also be provided to seal the charging port to achieve waterproof protection of the charging port and prevent liquid from entering the charging port and affecting its use. A control button electrically connected to the control mainboard may also be provided on the battery rod 11 to adjust the heating power of the heating element 111, so that the user can adjust the atomization power according to needs.

[0048] The control mainboard on the battery rod 11 is also electrically connected to a microphone, which is an airflow sensing element and is arranged in the airway connecting the battery rod 11 and the outside atmosphere. When the user inhales from the top of the atomizer 10, the gas in the airway 101 and the battery rod 11 is driven to flow, and the microphone is induced to transmit a signal to the control mainboard, and the control mainboard controls the heating element 111 to start heating. With such an arrangement, the atomizing device 100, in the standby state, determines whether to atomize based on the user's inhalation action. During the interval time when the user does not need to inhale, the heating element 111 does not work, thereby avoiding continued heating and atomization during the user's interval time, thereby improving the utilization rate of the atomized liquid.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
