Technical field

The present application relates to the field of atomization technology, and more specifically, to an atomization component and an electronic atomizer.

Background technique

Aerosol is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas matrix. Since aerosol can be absorbed by the human body through the respiratory system, it provides users with a new alternative absorption method. An atomizer refers to a device that forms an aerosol from stored atomizable substrates by heating or ultrasound. Atomizable substrates include e-liquids containing nicotine (nicotine), medical drugs, etc. Atomizing these substrates can deliver aerosols that can be inhaled to users, replacing conventional product forms and absorption methods.

Different atomization matrices have large viscosity differences due to different components. High-viscosity atomization matrices are difficult to flow into the atomization unit smoothly, and heat exchange bubbles are prone to appear and cause blockage, resulting in poor liquid supply and drying out of the heating element. Burning produces a burnt smell, which seriously affects the taste of the generated aerosol and limits the promotion and application of high-viscosity atomization matrix.

Referring to Figures 1 and 2, Figure 1 shows a schematic structural diagram of an atomization assembly according to an embodiment of the present application, and Figure 2 shows a schematic structural diagram of an atomization assembly according to an embodiment of the present application. An embodiment of the present application provides an electronic atomizer, including an atomizing component 100 and a battery component (not shown). The atomizing component 100 includes a main housing 120 and a heating unit 140 contained in the main housing 120 , the main housing 120 is used to store the aerosol-generating matrix, and the battery component is electrically connected to the heating unit 140. The heating unit 140 can heat the atomized aerosol-generating matrix under the action of the electric energy of the battery component to generate aerosol for the user to inhale. sol.

Specifically, the main housing 120 has a hollow shell-like structure, and the main housing 120 has an atomization chamber 121, an airflow channel 123 and a matrix storage chamber 125 inside. The atomization chamber 121 is located at one end of the main housing 120 in the axial direction and communicates with one end surface of the main housing 120 . One end of the airflow channel 123 is connected to the atomization chamber 121 , and the other end of the airflow channel 123 extends along the axial direction of the main housing 120 until it is connected to the other end surface of the main housing 120 . The matrix storage chamber 125 extends from one axial end of the main housing 120 to the other axial end of the main housing 120 and circumferentially surrounds the atomization chamber 121 and the airflow channel 123 .

In this way, the aerosol-generating matrix is stored in the matrix storage chamber 125 and gradually enters the atomization chamber 121 for heating and atomization during the use of the electronic atomizer.

In this application, the axial direction of the main housing 120 is the Z direction in FIG. 1 , the circumferential direction of the main housing 120 is the direction surrounding the central axis of the main housing 120 , and the radial direction of the main housing 120 is the direction of the main housing 120 . The central axis of the body 120 is a direction whose origin is perpendicular to the axial direction of the main housing 120 .

Please refer to FIG. 3 and FIG. 4 . FIG. 3 shows a schematic structural diagram of a heating unit according to an embodiment of the present application. FIG. 4 shows a schematic structural diagram of a heating unit according to an embodiment of the present application.

The heating unit 140 is partially housed in the atomization chamber 121 and is used to heat the aerosol that atomizes into the atomization chamber 121 to generate matrix to generate aerosols. Specifically, the heating unit 140 includes a liquid conduit 141 and a heating element 143. Part of the liquid conduit 141 is accommodated in the atomization chamber 121, and the other part extends into the matrix storage chamber 125. The heating element 143 is wound around the liquid conduit 141. It is contained outside the part inside the atomization chamber 121 . On the one hand, the liquid conduit 141 can play the role of supporting and fixing the heating element 143, and the heating element 143 can heat and atomize the aerosol-generating matrix entering the atomization chamber 121 to generate aerosol; on the other hand, the liquid conduit 141 The aerosol-generating matrix stored in the matrix storage chamber 125 may be heated.

In this way, through the arrangement of the conduit 141, the viscosity of the aerosol-generating matrix stored in the matrix storage chamber 125 can be reduced due to the increase in temperature, and has better fluidity. For example, at normal temperature, the viscosity of the aerosol-generating matrix is as high as 10 ⁶ cP, but when the temperature increases to about 70°C, the viscosity of the aerosol-generating matrix will decrease to less than 1000 cP. As the viscosity decreases, it not only increases the amount of aerosol generated by atomization of the aerosol-generating matrix, but also reduces the risk of burning due to the inability to timely flow into the atomization chamber 121 due to the viscosity being too high, thereby improving the performance of the electronic atomizer. Use experience.

Please refer to FIG. 1 again. In some embodiments, the conduit 141 heats the aerosol-generating matrix by conducting part of the heat generated by the heating element 143 into the matrix storage chamber 125 . Specifically, in one embodiment, the liquid conduit 141 is formed of a good thermal conductor. Good thermal conductors include but are not limited to aluminum alloy, brass and other thermally conductive metal materials. Therefore, the liquid conduit 141 has good thermal conductivity, so it can be The heat generated by the heating element 143 is efficiently conducted to the matrix storage cavity 125 . It can be understood that the material forming the catheter 141 is not limited thereto, and can be configured as needed to meet different requirements.

Please refer to FIG. 2 again. In other embodiments, the catheter 141 uses an active heating method to directly heat the aerosol-generating matrix in the matrix storage chamber 125 . Specifically, in one embodiment, the catheter 141 is made of a high-resistivity metal material. The high-resistivity metal material includes but is not limited to 316L, iron-chromium-aluminum, nickel-chromium and other metal materials. The catheter 141 is connected to the battery component through the pin 147 Electrically connected, the current of the battery assembly can be transmitted to the catheter 141 through the pin 147, so the catheter 141 can generate heat under the action of the electrical energy of the battery assembly to heat the aerosol-generating matrix in the matrix storage chamber 125, without relying on The heat generated by the heating element 143. It can be understood that the material forming the catheter 141 is not limited thereto, and can be configured as needed to meet different requirements.

In some embodiments, the conduit 141 can work synchronously with the heating body 143. While the heating body 143 heats and atomizes the aerosol-generating substrate, it also heats the aerosol-generating substrate stored in the substrate storage chamber 125. In other embodiments, the conduit 141 can also preheat the aerosol-generating matrix stored in the matrix storage chamber 125 before the heating element 143 heats the atomized aerosol-generating matrix, so that the mist is heated by the heating element 143 . Before decomposing the aerosol-generating matrix, reduce the viscosity of the aerosol-generating matrix and increase the fluidity of the aerosol-generating matrix to ensure smooth liquid supply.

It should be noted that in some embodiments, while the catheter 141 generates heat under the action of electric energy to heat the aerosol-generating matrix, the catheter 141 can also conduct the heat generated by the heating element 143 to the matrix storage through thermal conduction. cavity 125, thereby fully utilizing the heat generated by the heating element 143 and further reducing aerosol generation in the matrix storage cavity 125. The viscosity of the matrix.

As shown in Figures 1, 3 and 4, a liquid conduction chamber 1412 connected to the matrix storage chamber 125 is formed in the liquid conduit 141, and the cavity wall of the liquid conduction cavity 1412 is provided with a gap connecting the liquid conduction chamber 1412 and the atomization chamber 121. Liquid guide hole 1414. In this way, the aerosol-generating substrate in the substrate storage chamber 125 first enters the liquid conduction chamber 1412, and then flows through the liquid conduction hole 1414 to the atomization chamber 121 outside the liquid conduction cavity 1412, and then contacts the heating element 143 to form a vapor in the heating element 143. Aerosol is generated by atomization under the action of atomization. Since the liquid conduit 141 can reduce the viscosity of the aerosol-generating matrix near it, it can form a flow path for ventilation bubbles to facilitate the discharge of ventilation bubbles from the liquid conduit hole 1414, thus helping to solve the problem of clogging and accumulation of ventilation bubbles. Reduces risk of scorching.

Furthermore, the heating unit 140 also includes a liquid conductor 145. The liquid conductor 145 covers the liquid conductor 141 and covers the liquid conductor hole 1414. The heating element 143 is wound around the liquid conductor 145. In this way, the aerosol-generating matrix in the liquid-conducting chamber 1412 is introduced into the liquid-conducting member 145 through the liquid-conducting hole 1414 and evenly distributed in the liquid-conducting member 145. The heating element 143 contacts and heats the aerosol generated in the atomized liquid-conducting member 145. matrix to generate aerosols.

Specifically, in some embodiments, the catheter 141 is an integrally formed tubular structure, the liquid conduction chamber 1412 is disposed through the liquid conduction tube 141 in the axial direction, and the side wall of the liquid catheter 141 forms the wall of the liquid conduction cavity 1412 . In an embodiment in which the catheter tube 141 can actively generate heat to heat the aerosol-generating matrix, two axial ends of the catheter tube 141 respectively lead out pins 147, and the two pins 147 pass through the main housing 120 to connect with the battery respectively. The positive and negative terminals of the assembly are electrically connected to form a current path to heat the catheter 141 using resistance.

As shown in Figures 1 and 2, more specifically in one embodiment, the catheter 141 has a straight tubular structure, and the catheter 141 is placed transversely in the atomization chamber 121 along its own axis. The center of the catheter 141 The axial direction extends along a radial direction of the main housing 120, and the two axial ends of the catheter 141 respectively extend into the matrix storage cavity 125 along the aforementioned radial direction. The liquid-conducting member 145 is circumferentially wrapped outside the side wall of the liquid-conducting tube 141 , and the heating element 143 is circumferentially arranged around the outside of the liquid-conducting member 145 . A plurality of groups of liquid conduction holes 1414 are provided on the side wall of the liquid conduit tube 141. The plurality of groups of liquid conduction holes 1414 are arranged at intervals along the axial direction of the liquid conduit tube 141. All the liquid conduction holes 1414 in each group of liquid conduction holes 1414 are arranged along the axial direction of the liquid conduit tube 1414. 141 are arranged at circumferential intervals, so the aerosol-generating matrix in the liquid-conducting chamber 1412 can be evenly introduced into the liquid-conducting member 145 .

Further, the axial length of the catheter 141 is greater than the axial length of the liquid guide 145, and at least one axial end of the catheter 141 protrudes from the liquid guide 145 and extends into the matrix storage cavity 125, thereby affecting the matrix. The aerosol-generating matrix in the storage chamber 125 is atomized. Preferably, two axial ends of the liquid conduit 141 protrude from the liquid conduit member 145 and extend into the matrix storage chamber 125 respectively. It can be understood that in another embodiment, the axial length of the liquid conduit 141 may be equal to the axial length of the liquid guide member 145, and the two end surfaces of the liquid conduit 141 in the axial direction are respectively axially aligned with the liquid guide member 145. The two upward ends are flush with each other.

Specifically, in an embodiment in which the catheter 141 can actively generate heat to heat the aerosol-generating matrix, two portions of the catheter 141 The axial ends respectively protrude from the liquid guide 145 and extend into the matrix storage chamber 125. The two axial ends are electrically connected to one end of a pin 147, and the other end of the pin 147 is along the direction away from the air flow channel 123. The direction passes through the main housing 120 to electrically connect with the battery assembly.

In this way, by extending into the axial end of the matrix storage chamber 125, the catheter 141 can heat the aerosol-generating matrix in the matrix storage chamber 125. At the same time, the aerosol-generating matrix in the matrix storage chamber 125 can pass through the conductor. Both ends of the liquid pipe 141 open into the liquid conduction chamber 1412, and then pass through the liquid conduction holes 1414 to reach the liquid conduction member 145 and the heating element 143.

More specifically, in some embodiments, the cross section of the catheter 141 perpendicular to its own axis is annular, the inner diameter of the catheter 141 is 0.3mm-3mm, and the axial length of the catheter 141 is 3mm-30mm. . It can be understood that in other embodiments, the shape and size of the catheter 141 are not limited thereto, and can be set according to the size of the main housing 120 to meet different requirements.

Referring to Figures 5 and 6, in some embodiments, the catheter 141 is generally in a "U"-shaped tubular structure, including a support section 141a and two extension sections 141b.

Among them, the support section 141a is at least partially located in the atomization chamber 121 and extends along a radial direction of the main housing 120. The liquid guide 145 covers the outer wall of the support section 141a, and the heating element 143 is circumferentially arranged around the guide. Liquid parts 145 outside. Multiple groups of liquid conduction holes 1414 are arranged at axial intervals along the support section 141a. All liquid conduction holes 1414 in each group of liquid conduction holes 1414 are arranged at intervals along the circumferential direction of the support section 141a. Therefore, the air in the liquid conduction cavity 1412 can be The sol-generating matrix is evenly introduced into the liquid guide 145 .

The two extension sections 141b are connected to the opposite ends of the support section 141a in the axial direction, and extend along the radial direction of the support section 141a to one end of the matrix storage chamber 125 away from the atomization chamber 121. Each extension section 141b is also provided with a liquid conduction hole 1414, and the aerosol-generating substrate in the substrate storage chamber 125 can enter the extension section 141b through the liquid conduction hole 1414 provided in the extension section 141b.

In an embodiment in which the catheter 141 can actively generate heat to heat the aerosol-generating matrix, one end of the two extension sections 141b away from the support section 141a is electrically connected to one end of a pin 147, and the other end of the pin 147 is respectively along the The direction away from the air flow channel 123 passes through the main housing 120 to be electrically connected to the battery assembly. In some embodiments, the two pins 147 can also be electrically connected to both ends of the support section 141a respectively, thereby reducing the resistance in the current path and improving the heating efficiency. The two extension sections 141b are used to conduct the generated energy generated by the support section 141a. of heat.

In this way, the extension section 141b penetrates deep into the matrix storage chamber 125 to fully heat the aerosol-generating matrix, thereby effectively reducing the viscosity of the aerosol-generating matrix stored in the matrix storage chamber 125, and the aerosol-generating matrix in the matrix storage chamber 125 The liquid guide hole 1414 opened in the extension section 141b can be entered into the extension section 141b. Moreover, since the temperature of the aerosol-generating matrix near the extension section 141b is high and the viscosity is low, it can serve as a passage for ventilation bubbles, which is helpful for It solves the problem of bubble clogging and accumulation and further reduces the risk of scorching. It can be understood that the length of the extension section 141b is not limited and can be set as needed to meet heating requirements.

In some other embodiments, the catheter 141 is generally an "L" shaped tubular structure, including a support section 141a and an extension section 141b connected to either end of the support section 141 in the axial direction. The liquid conduit 141 can also have a roughly "H"-shaped tubular structure, including one support section 141a and four extension sections 141b, where two extension sections 141b are connected to one end of the support section 141a and are arranged along the axial direction of the main housing 120 , the other two extension sections 141b are connected to the other end of the support section 141a and are arranged along the axial direction of the main housing 120 . The liquid conduit 141 can also be roughly in the shape of a "丩" tubular structure, including a support section 141a and three extension sections 141b, one of which is an extension section 141b connected to one end of the support section 141a and arranged along the axial direction of the main housing 120. The other two extension sections 141b are connected to the other end of the support section 141a and are arranged along the axial direction of the main housing 120 . It can be understood that the catheter 141 may also include a support section 141a and other numbers of extension sections 141b. The extension sections 141b are connected to either end of the support section 141a and extend toward the matrix storage chamber 125, and the extension direction is not limited.

It can be understood that in an embodiment in which the catheter 141 can actively generate heat to heat the aerosol-generating matrix, one end of the two extension sections 141b away from the support section 141a is electrically connected to one end of a pin 147, and the pin 147 The other end passes through the main housing 120 along the radial or axial direction of the main housing 120 to be electrically connected to the battery assembly.

As shown in FIGS. 6 and 8 , since the extension section 141 b is far away from the heating element 143 , it is difficult to conduct heat from the heating element 143 to the matrix storage cavity 125 . Therefore, in one embodiment, it is preferred that the extension section 141 b has a protruding A plurality of heat dissipation fins 1416 are arranged at intervals along the extension direction of the extension section 141b. The arrangement of the heat dissipation fins 1416 effectively increases the contact area between the liquid conduit 141 and the aerosol generating substrate, thereby improving the heat conduction efficiency. It can be understood that the shape, number and arrangement of the heat dissipation fins 1416 are not limited and can be set as needed to meet different heat conduction efficiency requirements.

In the above embodiment, each liquid conducting hole 1414 may be circular, or may be in a regular or irregular shape such as an ellipse or a waist shape, and the equivalent diameter of each liquid conducting hole 1414 is 0.01 mm-3 mm. It can be understood that the number, arrangement and shape of the liquid conduction holes 1414 are not limited. The size and shape of each liquid conduction hole 1414 can be the same or different, and can be set as needed to meet the requirements of different liquid conduction effects.

In some embodiments, the liquid-conducting member 145 has a porous structure, such as natural organic cotton or organic synthetic polymer porous foam cotton. The liquid-conducting member 145 has a porosity of 0.45-0.99 and a permeability of 1× 10 ^-11 mm-1×10 ^-9 mm. Therefore, the aerosol-generating matrix in the liquid-conducting cavity 1412 can be fully absorbed through the liquid-conducting hole 1414, and the absorbed aerosol-generating matrix can be evenly distributed in the liquid-conducting member 145. It can be understood that in other embodiments, the material forming the liquid-conducting member 145 is not limited to this. Corresponding materials can be selected as needed to meet different liquid-conducting requirements, such as porous ceramics, foam metal, and other materials.

The heating element 143 is formed of at least one of a heating wire with a circular cross-section, a heating belt, or a heating mesh. Compared with the heating elements in columnar, block and other shapes in the prior art, the heating element 143 formed by a heating wire, a heating belt or a heating mesh in this application is a thin-walled structure with a smaller thickness, so the thermal resistance is smaller. Small, the generated heat can be effectively conducted to the catheter 141. It can be understood that in some other embodiments, the shape and size of the heating element 143 are not limited thereto and can be set as needed to meet different atomization requirements.

The above-mentioned atomization assembly 100 and electronic atomizer are provided with a liquid conduit 141 that has the functions of liquid conduction, heat conduction (or heating) and supporting the heating element 143, which can conduct part of the heat generated by the heating element 143 to the matrix storage cavity. The aerosol-generating matrix in 125, or the aerosol-generating matrix in the matrix storage chamber 125 is actively heated, so that the temperature of the aerosol-generating matrix is increased and the viscosity is reduced, thereby increasing the amount of aerosol generated by its atomization, and at the same time preventing Smooth drainage reduces the risk of scorching. Moreover, since the viscosity of the aerosol-generating matrix near the catheter tube 141 is low, a path for ventilation bubbles can be formed, which helps to solve the problem of clogging and accumulation of ventilation bubbles and reduce the risk of scorching.

The technical features of the above-described embodiments can be combined in any way. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, All should be considered to be within the scope of this manual.

The above-described embodiments only express several implementation modes of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application.
