Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an atomizer. Background Art

[0002] Existing atomizers mainly include a nozzle assembly, an atomizer assembly, a sealing assembly, an air flow channel, etc. The atomizer assembly usually includes an atomizer sleeve and an atomizer core accommodated in the atomizer sleeve. The atomizer sleeve stores atomized liquid. The atomizer core generates heat after being energized, heating the aerosol matrix into an aerosol that can be inhaled by the user. The aerosol matrix that is not completely atomized during heating will produce some condensed droplets or liquid surface on the side wall of the air flow channel during the inhalation process as the number of puffs increases. The generated droplets can be easily carried out with subsequent inhalations.

[0003] In order to solve the problem of liquid leakage during suction, the current common technical solution is to use absorbent cotton to absorb the condensed liquid droplets brought out by the airflow during suction, thereby reducing the risk of large particles of water droplets being brought into the mouth and causing liquid to be sucked in. This method increases the manufacturing cost due to the addition of parts and assembly steps, and because the absorbent cotton needs to be assembled, a certain amount of space needs to be sacrificed, so the structural parts need to be carefully designed to make room, which weakens the strength of the structural parts and reduces the stability.

[0027] The present application is described in detail below with reference to the accompanying drawings and optional embodiments. It should be noted that, under the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Figure 1 Schematic diagram of the atomizer structure of the first embodiment of the present application; Figure 1 As shown, as the first embodiment of the present application, a nebulizer 100 is disclosed, which includes a nozzle assembly 200, an atomizing assembly 300, a sealing assembly 400 and an air flow channel 500, wherein the atomizing assembly 300 forms atomized gas; the sealing assembly 400 is arranged between the nozzle assembly 200 and the atomizing assembly 300; the air flow channel 500 passes through the atomizing assembly 300, the sealing assembly 400 and the nozzle assembly 200, so that the atomized gas formed by the atomizing assembly 300 flows to the nozzle assembly 200; wherein the sealing assembly 400 is provided with a microgroove structure 450 on a surface away from the atomizing assembly 300, and the microgroove can absorb large particle droplets and / or incompletely atomized aerosol matrix in the air flow channel 500 through capillary force.

[0029] This application no longer uses the original upper sealing silicone and liquid-absorbing cotton to improve the leakage problem. This application integrates and improves the upper sealing silicone and liquid-absorbing cotton to obtain the sealing component 400 in this embodiment. The sealing component 400 in this embodiment actually replaces the original upper sealing silicone and suction nozzle liquid-absorbing cotton. A micro-groove structure 450 is provided on the sealing component 400. By utilizing the capillary suction ability of the micro-groove structure 450, during suction, large particles of liquid droplets in the airflow channel 500 will be adsorbed in the micro-groove by the micro-groove, thereby avoiding large particles of liquid droplets being brought out to the mouth during suction. In addition, there is no need to set up liquid-absorbing cotton, which can further reduce the number of parts, thereby reducing assembly cost and manufacturing cost.

[0030] Figure 2 is a schematic structural diagram of a sealing assembly according to a second embodiment of the present application; Figure 3 This is a cross-sectional schematic diagram of the sealing assembly structure of the second embodiment of the present application, refer to Figure 2 and Figure 3 As shown, as the second embodiment of the present application, the sealing component 400 in the above-mentioned first embodiment is further improved and refined. The sealing component 400 includes a first sealing portion 410, a second sealing portion 420 and a sink 430. The airflow channel 500 passes through the first sealing portion 410 and is connected to the sink 430. The second sealing portion 420 is arranged around the sink 430. The first sealing portion 410 is arranged below the sink 430. A plurality of ridges 440 are arranged in the sink 430 to form the microgroove structure 450. The sink 430 is equivalent to a liquid storage tank for the atomized gas formed by the atomizer assembly 300. In order to store large-particle liquid droplets better and faster, a convex strip 440 is provided on the sink 430 to form a micro-groove structure 450. The atomized gas formed by the atomizer assembly 300 flows through the air flow channel 500 to the micro-groove structure 450 on the sink 430. Through the capillary suction ability of the micro-groove, when inhaling, the large-particle liquid droplets in the air flow channel 500 will be adsorbed in the micro-groove, thereby eliminating the risk of large-particle liquid droplets being brought out into the mouth during inhalation.

[0031] In this embodiment, the design of the sealing assembly 400 consists of three main parts, namely the first sealing portion 410, the second sealing portion 420, and the sink 430. These components are all precisely manufactured using silicone material through one-piece molding technology. This process not only ensures seamless connection between components, but also significantly improves the sealing performance and reliability of the product. The design of the airflow channel 500 is ingenious, passing through the first sealing portion 410 and directly connected to the sink 430. This structural arrangement makes the gas flow smoother and also improves the atomization efficiency.

[0032] The second sealing portion 420 is designed to surround the sink 430, which not only enhances the sealing of the overall structure but also provides additional support and protection for the sink 430 through its specific layout. The first sealing portion 410 is located below the sink 430. This configuration further ensures a direct connection between the airflow channel 500 and the sink 430, optimizing the gas flow path and reducing energy loss during gas flow. The layout design of the ridges 440 within the sink 430 is an innovative feature of this application. These ridges 440 form a microgroove structure 450 within the sink 430, greatly increasing the contact area between the liquid and the gas. During the atomization process, these microgrooves 450 efficiently absorb and store large liquid droplets through the principle of capillary action. This design solves the problem of large liquid droplets being easily inhaled into the mouth in traditional atomization devices, significantly improving the user experience. In this process, the sink 430 acts as a liquid reservoir, temporarily storing the atomized gas generated by the atomization assembly 300 to better control the flow of gas and the storage of liquid.

[0033] In addition, the formation of the ridges 440 not only promotes the rapid storage of liquid, but also enhances the capillary suction capacity of the microgrooves through its fine structural design. This allows large liquid droplets in the airflow channel 500 to be effectively adsorbed in the microgrooves during suction, thereby preventing these large liquid droplets from being brought into the user's mouth during suction, reducing potential risks during use; through the unique design of the sealing component 400, the precise layout of the airflow channel 500, and the innovative structure of the sink 430 and ridges 440, not only the flow of atomized gas and the storage of large liquid droplets are optimized, but also the product's safety and atomization efficiency are significantly improved. These features enable this application to improve the user experience while also ensuring the high performance and high reliability of the product.

[0034] In order to avoid the blockage of the air flow channel 500 caused by the solidification of the liquid in the micro-groove structure 450, the second sealing portion 420 includes a sinking structure 421 and a protruding structure 422. The sinking structure 421 includes a sinking surface, the height of the sinking surface is lower than the height of the top of the protruding structure 422, and the top height of the ridge 440 is flush with the sinking structure 421, which is equivalent to reserving a certain space between the micro-groove structure 450 and the nozzle assembly 200 to ensure the flow of atomized gas, thereby effectively reducing the risk of blockage of the air flow channel 500 due to liquid solidification. Through this structural optimization, not only the efficiency of the product is improved, but also the service life of the product is extended. In addition, this design also helps to simplify the assembly process and improve the durability and reliability of the entire device.

[0035] Furthermore, along the air outlet direction of the air flow channel 500, the height of the microgroove structure 450 formed between adjacent ridges 440 is h, wherein 0<h≤2.5mm, and the height of the top of the ridge 440 is lower than the height of the top of the second sealing portion 420. In order to better achieve the drainage and storage of large-particle liquid droplets, the height is generally selected to be 2mm, so that a certain error can be allowed during preparation, that is, an error exceeding 0.5mm is still within a controllable range. The spacing between adjacent ridges 440 is the width of the microgroove structure 450, and the width of the microgroove structure 450 is s, where 0.3mm≤s≤0.5mm. Under the condition of height limitation, in order to avoid controlling the flow velocity and the volume of the microgroove structure 450, that is, by limiting the width and depth of the microgroove structure 450 to control the liquid storage volume of each microgroove structure 450, the flow between each microgroove structure 450 can be better achieved, and large particle liquid droplets and / or incompletely atomized aerosol matrix can be avoided from accumulating in the microgroove structure 450 near the air flow channel 500.

[0036] Among them, the sink 430 includes a long axis 431 and a short axis 432. Along the direction of the short axis 432, the sink 430 includes a first area 433 and a second area 434. The ridges 440 in the first area 433 and the second area 434 are distributed in a fishbone shape. The ridges 440 in the first area 433 and the second area 434 are symmetrically arranged along the long axis 431 to ensure the uniformity of the flow of the atomized gas to the micro-groove structures 450 on both sides, thereby avoiding the different flow rates of the atomized gas due to the different structures on both sides, which may cause blockage on one side after a long time.

[0037] Specifically, the trough 430 is structurally divided into a first region 433 and a second region 434 along the minor axis 432. The ridges 440 within each region are arranged in a fishbone-like pattern. Notably, the ridges 440 within the first region 433 and the second region 434 are symmetrically arranged along the major axis 431. This symmetrical layout ensures that the atomizing gas flows evenly to the microgrooves 450 on both sides. This design takes into account the dynamics of gas flow. The symmetrical layout of the ridges 440 promotes equal distribution of gas to the microgrooves 450 on both sides during flow. This innovation is crucial because it avoids differences in gas flow rate due to structural asymmetry. If the atomizing gas flow rate differs due to structural asymmetry, accumulated over time could cause clogging of the microgrooves 450 on one side, thereby affecting the stable operation and efficiency of the entire system. Therefore, this symmetrical design not only improves the reliability of the atomizing device but also extends its service life, ensuring a highly efficient and consistent atomization process.

[0038] Furthermore, the first sealing portion 410 is formed with a circular through groove 411, which is connected to the air flow channel 500. The ridges 440 close to the air flow channel 500 extend into the air flow channel 500. A small part of the ridges 440 is located in the air flow channel 500, which can guide the atomized gas into the micro-groove structure 450. The radius of the circular hole formed around the ends of all the ridges 440 extending to the air flow channel 500 is smaller than the radius of the circular through groove 411, thereby ensuring that most of the atomized gas flows from the air flow channel 500 to the nozzle assembly 200.

[0039] Among them, the ridges 440 include multiple first ridges 441 and multiple second ridges 442, the first ridges 441 are parallel to the short axis 432, and the angle between the second ridges 442 and the long axis 431 is a, wherein 0°<a<90°, the second ridges 442 are arranged at the edge of the air flow channel 500, and at least half of the second ridges 442 are located in the air flow channel 500. Among the multiple first ridges 441, some of the first ridges 441 extend to the air flow channel 500. The ridges 440 extending to the air flow channel 500 can better drain the atomized gas. When inhaling, large particle liquid droplets in the air flow channel 500 will be adsorbed in the microgrooves, further reducing the risk of large particle liquid droplets being brought out into the mouth during inhalation.

[0040] Specifically, the design of the ridges 440 includes multiple first ridges 441 and multiple second ridges 442. These first ridges 441 are arranged parallel to the minor axis 432. The second ridges 442 are arranged at an angle a relative to the major axis 431, where the angle a satisfies the condition 0° < a < 90°. This specific angle design allows the second ridges 442 to be installed at the edge of the airflow channel 500, with at least half of the second ridges 442 located within the airflow channel 500. This structural configuration allows a portion of the multiple first ridges 441 to extend into the airflow channel 500, thereby enhancing the drainage effect of the atomized gas. When inhaling, larger liquid droplets in the airflow channel 500 are effectively adsorbed within the microgrooves. This mechanism significantly reduces the risk of large liquid droplets being inhaled into the mouth during inhalation. This ingenious layout and design of the ridges 440 not only optimizes the flow dynamics of the atomized gas, but also improves user safety and the efficiency of the atomization process. Additionally, this design helps simplify the assembly process and improves the durability and reliability of the entire device.

[0041] Figure 4 1 is a schematic structural diagram of an atomizer according to a third embodiment of the present application; Figure 5 This is a schematic diagram of the sealing structure of the atomizer of the third embodiment of the present application. As the fourth embodiment of the present application, it is a further improvement and refinement of any of the above embodiments. Figure 4 and Figure 5 As shown, the height of the bottom of the first sealing part 410 is lower than the height of the bottom of the second sealing part 420, and the first sealing part 410 and the second sealing part 420 form an annular groove 460 near one end of the atomizer assembly 300. The atomizer assembly 300 includes a protrusion 310, and the annular groove 460 can achieve a fixed seal with the protrusion 310 of the atomizer assembly 300.

[0042] In this embodiment, in the present application, the bottom position of the second sealing portion 420 is designed to be at a lower height relative to the bottom of the first sealing portion 410. This specific height configuration allows the first sealing portion 410 and the second sealing portion 420 to jointly form an annular groove structure when they are close to the atomizing assembly 300. The atomizing assembly 300 is particularly provided with a protrusion 310, the function of which is to be able to be embedded in the aforementioned annular groove 460. Through this structural coordination, stable fixation and effective sealing between the atomizing assembly 300 and the sealing component can be achieved. This design cleverly utilizes the mutual coordination between physical structures to ensure that during use, even under various complex external environmental conditions, the system's airtightness can be maintained to avoid any possible liquid leakage. In addition, such a structural arrangement also helps to simplify the assembly process and improve the durability and reliability of the entire device.

[0043] It should be noted that the concept of this application can form a large number of embodiments, but the length of the application document is limited and it is impossible to list them one by one. Therefore, under the premise of no conflict, the embodiments or technical features described above can be arbitrarily combined to form new embodiments. After the embodiments or technical features are combined, the original technical effects will be enhanced.

[0044] The above content is a further detailed description of the present application in conjunction with specific optional implementation methods, and the specific implementation of the present application cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be considered to fall within the scope of protection of the present application.
