Description

Technical Field

[0001] The present application relates to the technical field of electronic atomization, and more specifically to an atomizer and an electronic atomization device. Background Art

[0002] Atomization equipment is a type of product that uses the thermal effect of a heating element to heat the atomization matrix so that the atomization matrix generates an aerosol without combustion. A single heating element is generally used inside the atomizer. The disadvantage of this is that the amount of atomization generated by a single heating element is not large enough to meet the needs of the user. In order to increase the amount of atomization, currently the method of reducing the resistance of the heating element or increasing the driving voltage at both ends of the heating element is mostly used. Both methods can increase the heating power of the heating element, thereby increasing the atomization amount of the atomization matrix. However, during the use of higher power, a single heating element is prone to high-temperature carbon deposition and easy to burn the core, which affects the user's taste and the service life of the atomization equipment.

[0026] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0027] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0028] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0029] In the existing atomization equipment, the atomization core of the atomizer uses a single heating element to heat the atomization matrix. The atomization amount of the single heating element is small, which is achieved by reducing the resistance of the heating element or increasing the driving voltage at both ends of the heating element. Both methods can increase the heating power of the heating element. Although it can increase the atomization amount, it is also easy to cause high-temperature carbon deposition and core sticking due to excessive power, which affects the taste of the aerosol generated after the atomization matrix is ​​heated and also reduces the service life of the atomization core. In order to solve this technical problem, this application provides the following technical solution content.

[0030] refer to Figure 1-7 The present application provides an electronic atomization device, which includes an atomizer 100 and a power supply component 200. The power supply component 200 is configured to provide the atomizer 100 with the power required for operation. The atomizer 100 heats and atomizes an atomization matrix therein to form an aerosol for use (inhalation) by a user.

[0031] It should be noted that the term aerosol refers to a dispersion of solid particles or liquid particles in a gas. "Aerosol" as used herein can generally be used to refer to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form to an inhalable form containing suspended solid or liquid drug particles.

[0032] As used herein, the atomizing substrate is also referred to as an aerosol-forming substrate, and the term "aerosol-forming substrate" refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that is substantially resistant to thermal degradation at the operating temperature of the system) during use. Suitable aerosol formers are well known in the art and include, but are not limited to: polyols, such as triethylene glycol, 1,3-butylene glycol, and glycerol; esters of polyols, such as glycerol mono-, di-, or triacetate; and aliphatic esters of mono-, di-, or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetradecanedioate.

[0033] refer to Figure 1-4The atomizer 100 includes an outer shell 110, an atomizer core 120 and an electrode assembly 130. The outer shell 110 has a receiving cavity 111. The atomizer core 120 is arranged in the receiving cavity 111. The atomizer core 120 includes a plurality of heating elements 121. The heating elements 121 are used to heat the atomization matrix. Each heating element 121 has a first terminal and a second terminal, which serve as the positive and negative electrodes of the heating element 121 connection circuit. After being electrically connected to the power supply assembly 200, the heating element 121 can generate heat after being energized. The electrode assembly 130 is used to realize the electrical connection between the heating element 121 and the power supply assembly 200. The heating element 121 is arranged on the outer shell 110. The electrode assembly 130 includes a common electrode 131 and a plurality of dedicated electrodes 132. The first terminals of the plurality of heating elements 121 are all electrically connected to the common electrode 131. The second terminals of the plurality of heating elements 121 are electrically connected to the dedicated electrodes 132 one by one, so that the plurality of heating elements 121 are connected in parallel.

[0034] By setting a common electrode 131 and a plurality of dedicated electrodes 132 corresponding to the number of heating elements 121, the plurality of heating elements 121 are connected in parallel. When the power in the circuit connected to the plurality of heating elements 121 is consistent with that of the existing single heating element 121, the total power is evenly distributed to each heating element 121 due to the parallel connection of the plurality of heating elements 121, thereby reducing the power at the single heating element 121, and reducing the risk of high-temperature carbon deposition and core sticking under the same total amount of atomization. When the total power is increased and the power of each heating element 121 in the plurality of heating elements 121 is consistent with the power of the existing single heating element 121, the total power is increased, and the atomization amount of the entire atomizer 100 is increased, thereby improving the user experience and increasing the service life of the atomizer core 120. By setting a common electrode 131, the number of electrodes can be reduced, the circuit structure can be optimized, and thus the structure of the atomizer 100 is optimized, space is saved, and wiring difficulty is reduced.

[0035] In order to achieve the connection between the heating element 121 and the electrode assembly 130, the atomizer core 120 also includes a first pin 122 and multiple second pins 123. One end of the first pin 122 is electrically connected to the common electrode 131, and the other end is electrically connected to the first terminal of the heating element 121. One end of the multiple second pins 123 is electrically connected to the dedicated electrode 132 one by one, and the other end is electrically connected to the second terminal of the heating element 121 one by one.

[0036] Of course, in other embodiments, each heating element 121 may have two pins, and the positive or negative pins of the plurality of heating elements 121 may be connected to the common electrode 131 , and the other pins may be connected to the dedicated electrodes 132 in a one-to-one correspondence.

[0037] The setting of the shared first pin 122 can also reduce the wiring inside the atomizer core 120, reduce the assembly process and reduce the difficulty of assembly, and can also avoid that too many lines affect the operation of the atomizer core 120, such as too many lines affecting the circulation of airflow in the atomizer core 120.

[0038] refer to Figure 3 The atomizing core 120 further includes a mounting bracket 124, a liquid guide 125 and an atomizing tube 126. The atomizing tube 126 and the mounting bracket 124 form an installation space. The liquid guide 125 and the heating element 121 are arranged in the installation space. The liquid guide 125 extends along the axial direction of the atomizing tube 126. The liquid guide 125 is used to guide the atomized matrix to flow toward the heating element 121. A plurality of heating elements 121 are arranged side by side on the inner side of the liquid guide 125 along the extension direction of the liquid guide 125. The surface where the liquid guide 125 and the heating element 121 are attached is the surface where the heating element 121 heats and atomizes. The heat is conducted to the surface by the heating element 121. The atomized matrix on the surface guided by the liquid guide 125 is heated and atomized to form an aerosol. Multiple heating elements 121 share the same liquid guiding member 125 and are simultaneously arranged in the extension direction of the liquid guiding member 125, which can increase the surface area of ​​the heating element 121 for heat and atomization. Since the liquid guiding member 125 guides the flow direction of the atomized matrix to be roughly perpendicular to its extension direction, the multiple heating elements 121 are arranged in parallel along the extension direction, which can also ensure that the liquid intake of the multiple heating elements 121 is consistent, thereby avoiding the risk of core sticking at a location with a small amount of liquid intake and the risk of sucking into the liquid atomized matrix at a location with a large amount of liquid intake due to uneven liquid intake under the same power.

[0039] refer to Figure 5 The atomizer core 120 includes a first heating element 1211 and a second heating element 1212, and the first heating element 1211 and the second heating element 1212 are arranged side by side on the inner side of the liquid guide member 125 along the extension direction of the liquid guide member 125. Of course, in other embodiments, three heating elements 121 or four heating elements 121 may be arranged according to design requirements, which is subject to market demand, etc., and will not be described in detail here.

[0040] Correspondingly, two dedicated electrodes 132 are provided, namely, a first dedicated electrode 1321 and a second dedicated electrode 1322 , and two second pins 123 are also provided, namely, a second pin A 1231 and a second pin B 1232 .

[0041] refer to Figure 2 and Figure 3The outer shell 110 includes a main shell 112, a suction nozzle 113 and a base 114. The suction nozzle 113 and the base 114 are correspondingly arranged at the two ends of the main shell 112 and are sealed and connected to the main shell 112 to enclose and form a receiving chamber 111. The base 114 is provided with mounting holes 1141. The number of mounting holes 1141 is adapted to the electrode assembly 130. When the electrode assembly 130 includes a common electrode 131 and two dedicated electrodes 132, the number of mounting holes 1141 is 3. The electrode assembly 130 is arranged in the mounting holes 1141. At least part of the structure of the electrode assembly 130 is exposed in the receiving chamber 111. The first pin 122 and the plurality of second pins 123 of the heating element 121 are accommodated in the receiving chamber 111 and extend to be electrically connected to the electrode assembly 130. The first pin 122 and the plurality of second pins 123 and the electrode assembly 130 can be fixedly connected by welding.

[0042] The atomizer 100 also includes a liquid storage tank 140, which is arranged in the accommodating cavity 111. The liquid storage tank 140 is used to store atomized matrix. The suction nozzle 113 is detachably connected to the main shell 112. A liquid injection port 141 is provided on the liquid storage tank 140 for replenishing the atomized matrix into the liquid storage tank 140. Through the detachable connection between the suction nozzle 113 and the main shell 112, the liquid injection port 141 can be exposed or closed to facilitate the replenishment of the atomized matrix in the liquid storage tank 140, thereby realizing multiple reuse of the atomizer 100.

[0043] In order to check the capacity of the atomized matrix in the liquid storage bin 140 in real time so as to replenish it in real time and avoid the risk of the atomized matrix not being replenished in time and causing the core to burn, the main housing 112 at the liquid storage bin 140 is made of a transparent material. The liquid storage bin 140 can also be provided with scale lines for quantitative observation.

[0044] Of course, in other embodiments, a liquid level sensor or other device may be provided in the liquid storage tank 140 to realize automatic and real-time observation of the atomized substrate capacity in the liquid storage tank 140 .

[0045] In order to avoid leakage from the connection between the main shell 112 and the suction nozzle 113 and the base 114, which may contaminate the entire atomizer 100 or even the electronic atomization device, a first sealing gasket 150 and a second sealing gasket 160 are also included. The first sealing gasket 150 is arranged between the suction nozzle 113 and the main shell 112, and the second sealing gasket 160 is arranged between the base 114 and the main shell 112.

[0046] At the same time, since a liquid injection port 141 is provided on the liquid storage tank 140, and the liquid injection port 141 is arranged on a side close to the suction nozzle 113, in order to further improve the sealing performance, a liquid blocking member 170 is also provided between the first sealing gasket 150 and the liquid storage tank 140, and the liquid blocking member 170 is made of a silicone material that can isolate liquid.

[0047] When the atomized matrix leaks, it may also flow to the base 114, thereby affecting the electrode assembly 130 on the base 114 and even affecting the power supply assembly 200. A liquid absorbent 180 is also arranged between the second sealing pad 160 and the base 114. The liquid absorbent 180 can absorb and store the atomized matrix, and can prevent the atomized matrix in the accommodating cavity 111 from flowing toward the electrode assembly 130. Even when there is condensed liquid in the accommodating cavity 111, the liquid absorbent 180 can also prevent the condensed liquid from flowing toward the electrode assembly 130.

[0048] In order to improve the convenience of using the electronic atomization device, the power supply assembly 200 and the atomizer 100 are detachably connected, and the connection can be achieved by snap connection, magnetic connection or threaded connection.

[0049] In order to conveniently provide the atomizer 100 with the power required for operation and simplify the assembly steps, the power supply component 200 includes a first power supply electrode 210 and a plurality of second power supply electrodes 220. The first power supply electrode 210 contacts the common electrode 131, and the plurality of second power supply electrodes 220 contact the dedicated electrodes 132 one by one, so as to achieve circuit conduction.

[0050] In one embodiment, the structures of the first power supply electrode 210 and the common electrode 131 match, and the structures of the plurality of second power supply electrodes 220 and the dedicated electrode 132 match, such as the first power supply electrode 210 and the second power supply electrode 220 are both convex structures, and the common electrode 131 and the dedicated electrode 132 are both concave structures, the first power supply electrode 210 and the common electrode 131 are plugged together to achieve circuit conduction, and the second power supply electrode 220 and the dedicated electrode 132 are plugged together to achieve circuit conduction.

[0051] Of course, in other embodiments, the first power supply electrode 210 and the second power supply electrode 220 are both recessed structures, and the common electrode 131 and the dedicated electrode 132 are both convex structures.

[0052] When two heating elements 121 are provided, two second power supply electrodes 220 are provided accordingly, namely, a second power supply electrode A221 and a second power supply electrode B222. The second power supply electrode A221 is in contact and conduction with the first dedicated electrode 1321, and the second power supply electrode B222 is in contact and conduction with the second dedicated electrode 1322.

[0053] refer to Figure 6 and 7The power supply assembly 200 further includes a power supply housing 230, a switching switch 240 and a control assembly 250. The control assembly 250 is disposed in the power supply housing 230, the switching switch 240 is disposed on the power supply housing 230, the switching switch 240 and the control assembly 250 are electrically connected, and the switching switch 240 can control the multiple heating elements 121 to work alternately or simultaneously, so as to facilitate the user to adjust the working state of the heating element 121 according to the use requirements (such as the atomization amount requirement). By triggering the switching switch 240, such as the number of times the switching switch 240 is triggered or the position of the switching switch 240 is moved, the control assembly 250 can adjust the multiple heating elements 121 to work alternately or simultaneously according to the trigger command.

[0054] There are multiple heating elements 121 in one atomizer core 120 at the same time, which can solve the problems of abnormal smoking taste and burning. On the one hand, when working with the control component 250, one of the multiple heating elements 121 can be used for alternate switching, thereby reducing the fatigue of a single heating element 121 and reducing the generation of carbon deposits; on the other hand, when it is designed that multiple heating elements 121 in an atomizer core 120 work at the same time, the heating area is increased, and the contact area with the liquid guide 125 is also increased, so that the smoking taste and the life of the heating element 121 are also improved, so that the service life of the electronic atomization device is longer and more stable.

[0055] The outer shell 110 of the atomizer 100 is also provided with an air flow channel 190, which includes an air outlet section, an air inlet section and an atomization section connected to the mouthpiece 113. The atomization section is arranged in the liquid storage bin 140 and is isolated from the liquid storage bin 140. The atomization core 120 is arranged in the atomization section. The aerosol formed by heating and atomization of the heating element 121 of the atomization core 120 passes through the atomization section and the air outlet section in sequence to be discharged from the outer shell 110. The air inlet section is connected to the outside air, so that the outside air passes through the atomization section and carries the aerosol of the atomization section to be discharged from the outer shell 110 through the air outlet section.

[0056] An air inlet hole 231 is provided on the power supply shell 230, and the air inlet hole 231 is connected to the above-mentioned air inlet section. External air enters the electronic atomization device through the air inlet hole 231, and then flows to the atomization section and the air outlet section in sequence through the air inlet section.

[0057] In order to ensure the air pressure balance in the electronic atomization device and ensure that the atomized matrix flows evenly to the atomization core 120, the liquid guide 125 also has an air guide function during the liquid guide process, and adjusts the air pressure balance inside and outside the liquid storage tank 140 through air guide. Of course, this part belongs to the publicly known technology and will not be described in detail.

[0058] In one embodiment, the switching switch 240 is linked to the air inlet 231, and the switching switch 240 includes a closing piece. The air intake at the air inlet 231 is adjusted by moving the closing piece to block the area of ​​the air inlet 231. The air flow sensor monitors the air intake and transmits the monitoring result to the control component 250. The control component 250 adjusts the multiple heating elements 121 to work alternately or simultaneously according to the air intake.

[0059] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
