Description

Technical Field

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

[0002] Electronic atomizers are widely used in electronic cigarettes, medical atomizers and other fields. Their core structure usually includes an electronic control component and an atomizing component. The battery in the electronic control component powers the atomizing component. External airflow enters the atomizing component through the air intake channel of the electronic control component, mixes with the aerosol produced by the atomizing component and is then discharged.

[0003] During atomization, after the atomizing medium is heated and atomized, some of the high-temperature aerosol condenses upon contact with low-temperature components, forming liquid condensate. This phenomenon is a common problem in existing e-cigarettes. The resulting condensate (and leaked atomizing liquid) can easily drip along the gaps onto the battery inside the electronic control components, potentially causing a short circuit and safety hazard. It can also accumulate in the air intake channel, interfering with the smooth flow of external airflow and causing microphone malfunction (in e-cigarettes with negative pressure microphone activation), thus affecting atomization efficiency and user experience.

[0004] To address the aforementioned issues, Chinese patent CN220441909U discloses an electronic atomizing device in which an adsorption component covers the outer periphery of an energy storage component. An inclined channel is formed around the outer periphery of the energy storage component, preventing the atomized liquid or condensate from leaking directly from the bottom of the atomizer along the length of the energy storage component onto the start switch. However, to form this inclined channel, the unfolded shape of the adsorption component cannot be a regular square shape. This undoubtedly increases the difficulty of cutting and shaping the adsorption component. Furthermore, the irregular shape of the adsorption component occupies additional storage space, resulting in higher production and storage costs. Additionally, the inclined channel increases the airflow path, prolonging the airflow distance and increasing flow resistance. Utility Model Content

[0005] The main purpose of this application is to provide an electronic control component and an electronic atomizer to solve the technical problems of safety hazards and air intake caused by liquid flowing into the electronic control component.

[0006] To achieve the above objectives, the first aspect of this application provides an electronic control component, the electronic control component comprising:

[0015] Optionally, the electronic control component includes:

[0016] A mounting base is disposed within the bottom end of the housing assembly, and the interior of the mounting base forms an air intake passage communicating with the vent passage and the air inlet; and

[0017] A pressure sensor is installed inside the air intake duct, with the air intake port and the air passage connected to both sides of the pressure sensor, respectively.

[0018] Optionally, the mounting base is inserted into the ventilation channel, and the mounting base is connected to the liquid suction element.

[0019] Optionally, the portion of the air intake near the ventilation channel extends vertically and has at least two deceleration protrusions protruding from its inner wall.

[0020] A second aspect of this application provides an electronic atomizer, the electronic atomizer comprising:

[0021] Atomizing components; and

[0022] The electronic control component described in any one of the above, wherein the electronic control component is connected to the atomizing component, and the air outlet is connected to the atomizing component.

[0024] In the electronic control component of this application, the air passage adopts a vertical straight-channel design, which has a short and smooth flow path, significantly reducing airflow resistance.

Even when the electronic atomizer is used vertically in a conventional manner, the condensate and leaked atomized liquid will not flow out of the air passage under the action of the liquid suction component, thus eliminating the need to consider the problem of straight dripping of liquid in a vertical state.

[0036] This application discloses an electronic control assembly, which includes a housing assembly, a battery, and a liquid-absorbing component. The housing assembly has an outlet and an inlet, with the inlet located below the outlet. The battery is disposed within the housing assembly. The liquid-absorbing component is disposed outside the battery and has a venting channel at both ends connecting the outlet and the inlet, respectively. The horizontal width of the venting channel is greater than or equal to 4 mm and less than or equal to 5.5 mm, and the venting channel is straight and extends vertically.

[0037] In the electronic control component of this application, the air passage adopts a vertical straight-channel design, which has a short and smooth flow path, significantly reducing airflow resistance. Furthermore, the vertical straight-channel structure allows the liquid suction component to unfold into a regular rectangle or square shape, greatly reducing the difficulty of cutting and forming. The regular shape also reduces the storage space occupied, effectively controlling production and storage costs. The horizontal width of the air passage formed by the liquid suction component is 4 to 5.5 mm. This size precisely matches the capillary action characteristics of the liquid suction component, ensuring that it automatically absorbs the condensate and leaked atomized liquid in the air passage. Even when the electronic atomizer is used vertically in a conventional manner, the condensate and leaked atomized liquid will not flow out of the air passage under the action of the liquid suction component, thus eliminating the need to consider the problem of straight dripping of liquid in a vertical state.

[0038] Please see Figures 1 to 3 The following will mainly describe the specific structure of the electronic control components.

[0039] The electronic control component of this application includes a housing assembly 100, which has an air outlet 121 and an air inlet 131, with the air inlet 131 located below the air outlet 121.

[0040] The housing assembly 100 includes an outer shell 110, a connecting seat 120, and a bottom shell 130. The outer shell 110 is cylindrical. The connecting seat 120 is located in the middle of the outer shell 110 and seals the inner wall of the outer shell 110, and an air outlet 121 is opened in the connecting seat 120. The bottom shell 130 is located at the bottom end of the outer shell 110 and covers the bottom end of the outer shell 110, and an air inlet 131 is opened in the bottom shell 130.

[0041] The electronic control component of this application includes a battery 200, which is disposed within the housing assembly 100 and within the outer casing 110, located below the connector 120.

[0042] The bottom surface of the connector 120 extends downward to form at least two abutment protrusions 122, which are arranged circumferentially along the connector 120. The bottom ends of the at least two abutment protrusions 122 abut against the top end of the battery 200. The circumferentially distributed abutment protrusions 122 can axially limit the battery 200, prevent the battery 200 from shaking, improve assembly stability, and the evenly distributed force abutment method can prevent local pressure damage to the battery 200.

[0043] The abutment protrusion 122 can taper in a stepped manner in the downward direction, thereby increasing the gas-accommodating space at the bottom of the abutment protrusion 122 and making the airflow smoother. The abutment protrusion 122 can be in a two-step shape.

[0044] The battery 200 is cylindrical, and its axis is parallel to the vertical direction. This design is suitable for the conventional vertical use of the electronic atomizer 10, effectively utilizing the internal longitudinal space and facilitating a compact overall layout.

[0045] The electronic control component of this application includes a liquid-absorbing element 300, which is disposed outside the battery 200. The liquid-absorbing element 300 is made of a porous material and is capable of automatically absorbing liquid through capillary action.

[0046] The liquid suction component 300 has a vent 310 with an outlet 121 and an inlet 131 at both ends. The vent 310 is a straight channel extending vertically. The vertical straight channel design of the vent 310 results in a short and smooth flow path, which significantly reduces airflow resistance. Furthermore, the vertical straight channel structure allows the liquid suction component 300 to unfold into a regular rectangle or square shape, greatly reducing the difficulty of cutting and forming. The regular shape also reduces the storage space occupied, effectively controlling production and storage costs.

[0047] The horizontal width of the vent 310 is greater than or equal to 4 mm and less than or equal to 5.5 mm. This dimension precisely matches the capillary action characteristics of the suction element 300, ensuring that it automatically draws out condensate and leaked atomized liquid from the vent 310. Even when the electronic atomizer 10 is used vertically as usual, condensate and leaked atomized liquid will not flow out of the vent 310 under the action of the suction element 300, thus eliminating the need to consider the issue of straight dripping of liquid in a vertical position. Furthermore, the horizontal width of the vent 310 can be 4–5.3 mm, 4.5–5.3 mm, 4.8–5.1 mm, 4.1–4.5 mm, 4–4.5 mm, 4.2–4.8 mm, or 4.3–5 mm, etc.

[0048] The liquid-absorbing component 300 surrounds the peripheral wall of the battery 200, and the horizontal cross-section of the liquid-absorbing component 300 is C-shaped. As a result, the liquid-absorbing component 300 can fit tightly against the peripheral wall of the battery 200, maximizing the contact area between the liquid-absorbing component 300 and the space surrounding the battery 200, and providing a sufficient carrier for liquid adsorption.

[0049] The liquid-absorbing component 300 is bonded to the battery 200. This connection method can enhance the tightness of the fit between the liquid-absorbing component 300 and the battery 200, prevent liquid from accumulating in the assembly gap, and simplify the installation process.

[0050] The liquid suction component 300 is connected to the housing assembly 100 on the side opposite to the battery 200. By connecting the housing assembly 100 and the battery 200 simultaneously through the liquid suction component 300, the battery 200 can be better secured, preventing the battery 200 from shaking or shifting within the housing assembly 100.

[0051] The interference fit between the liquid-absorbing component 300 and the battery 200 and the housing assembly 100 is greater than or equal to 0 and less than or equal to 0.4 mm. This parameter avoids both insufficient interference fit leading to loose assembly and liquid accumulation in gaps, and excessive interference fit causing deformation of the liquid-absorbing component 300 and damage to the capillary adsorption structure. Further, the interference fit can be 0.1–0.3 mm, 0–0.3 mm, 0.1–0.2 mm, 0–0.2 mm, 0.2–0.3 mm, 0.1–0.4 mm, or 0.2–0.4 mm, etc.

[0052] The ventilation channel 310 is located below the interval between two adjacent abutting protrusions 122. The air outlet 121, the interval between the two adjacent abutting protrusions 122 located above the ventilation channel 310, and the ventilation channel 310 are connected in sequence. Thus, through the sequential connection of the air outlet 121, the aforementioned interval, and the ventilation channel 310, a smooth airflow channel (flowing from the ventilation channel 310 to the air outlet 121) can be constructed. At the same time, the condensate and atomized liquid flowing down from the air outlet 121 flow from the aforementioned interval to the ventilation channel 310 (due to gravity) and are absorbed by the liquid suction member 300.

[0053] The electronic control assembly includes a mounting base 400 and a pressure sensor 500. The mounting base 400 is located inside the bottom end of the housing assembly 100 and can be sealed within the bottom shell 130. The mounting base 400 can be made of an elastic material (e.g., silicone, plastic, and / or rubber). An air inlet 410 is formed inside the mounting base 400, connecting the air passage 310 and the air inlet 131. The pressure sensor 500 is located within the air inlet 410, with its two sides connected to the air inlet 131 and the air passage 310, respectively. This enables the airflow triggering function of the pressure sensor 500. Specifically, when the user inhales, a negative pressure is formed within the air passage 310, causing a change in air pressure on both sides of the pressure sensor 500. The pressure sensor 500 detects this change and triggers the control unit of the electronic control assembly. The control unit then controls the atomizing component 600 of the electronic atomizer 10 (described in detail below) to begin atomization.

[0054] Furthermore, if the atomizing liquid leaks or condensates within the electronic control assembly, it can flow down to the pressure sensor 500, potentially causing the pressure sensor 500 to automatically activate and the electronic atomizer 10 to malfunction. The electronic control assembly of this application, through the absorption of liquid within the air passage 310 by the liquid suction element 300, can prevent liquid from flowing to the pressure sensor 500 and causing malfunctions.

[0055] The mounting base 400 is partially inserted into the ventilation channel 310, and the mounting base 400 is connected to the liquid suction component 300. This connection method not only achieves precise positioning of the mounting base 400 and the ventilation channel 310, but also strengthens the fixing effect through the liquid suction component 300, preventing the mounting base 400 from shifting. The portion of the air inlet 410 near the ventilation channel 310 (including the portion inserted into the ventilation channel 310 and the portion located outside the ventilation channel 310) can be adapted to the shape of the ventilation channel 310, and is roughly square.

[0056] The portion of the air intake duct 410 near the air passage 310 extends vertically and has at least two velocity-reducing protrusions 411 protruding from its inner wall. These at least two velocity-reducing protrusions 411 are located on different sides of the air intake duct 410, have different heights, and both have an upward-sloping end near the interior of the air intake duct 410. The staggered distribution of these velocity-reducing protrusions 411 alters the airflow direction and extends the airflow path, thereby effectively reducing the airflow velocity and minimizing noise generated by turbulent airflow impacting the walls of the air intake duct 410.

[0057] This application also proposes an electronic atomizer 10, which includes an atomizing component 600 and the aforementioned electronic control component. The electronic control component is connected to the atomizing component 600, and the air outlet 121 is connected to the atomizing component 600. The atomizing component 600 is used to atomize the atomized liquid under the control of the electronic control component. The electronic atomizer 10 of this application includes the aforementioned electronic control component and therefore possesses all the beneficial effects of the aforementioned electronic control component, which will not be elaborated further.

[0058] The atomizing component 600 is located inside the housing 110 and above the connector 120, while the battery 200 is located inside the housing 110 and below the connector 120. The connector 120 connects the atomizing component 600 and the battery 200. This vertical arrangement of "atomizing component 600 - connector 120 - battery 200" significantly optimizes internal space utilization, resulting in a more compact design.

[0059] The connector 120 is made of an elastic material (such as silicone, plastic and / or rubber). This design not only enhances the sealing connection between the connector 120 and the atomizing assembly 600, battery 200 and housing 110, effectively preventing liquid leakage along the gaps between components, but also provides good shock absorption, protecting the core components such as the atomizing assembly 600 and battery 200 when the electronic atomizer 10 is subjected to impact or vibration.
