Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to an atomizer and electronic atomization device. Background Technology

[0002] Atomizers contain two important components: an oil guide and a heating element that are connected to each other. After the atomizing medium is introduced into the oil guide, the heating element comes into contact with the atomizing medium in the oil guide. When the heating element is powered on, it can atomize the atomizing medium in contact with the heating element.

[0003] The atomization channel for the atomized medium to flow out is located on the side closer to the heating element. Therefore, the oil supply channel for the atomized medium to enter the oil guide body is located on the side closer to the oil guide body, which makes the overall structure wider and is not conducive to the miniaturization of the atomizer.

[0037] Example 1:

[0038] Reference Figure 1-7 This embodiment discloses an electronic atomizing device, which includes a power supply device and an atomizer. The atomizer includes a support 100, a heating element 200, and an oil guide 300. The support 100 is provided with an atomization channel 115 and an oil inlet channel 117. The atomization channel 115 includes an atomization groove 116. The oil inlet channel 117 includes an oil outlet 118.

[0039] The bracket 100 includes a support 110 and a silicone body 120. The support 110 has a mounting surface 111 with a receiving groove, and the silicone body 120 is installed in the receiving groove. An atomizing groove 116 is formed in the side of the silicone body 120 facing the same direction as the mounting surface 111, that is, the atomizing groove 116 penetrates the mounting surface 111. In other embodiments, the bracket 100 may not include the silicone body 120, and the atomizing groove 116 may be formed in the middle of the mounting surface 111 and penetrate the mounting surface 111.

[0040] The oil outlet is located on the mounting plane 111. Both the atomizing groove 116 and the oil outlet 118 are located on the back side of the mounting plane 111, and the atomizing groove 116 and the oil outlet 118 are arranged at intervals.

[0041] The wicking body 300 is a rigid wicking body, which can be a glass substrate or ceramic substrate with capillary channels (such as porous ceramic or porous glass). The heating element 200 is a conductive coating, heating wire, or heating mesh integrally formed on the substrate. That is, the heating element 200 and the wicking body 300 together constitute part or all of the atomizing core 400, which is flat. The wicking body 300 is mounted on the mounting plane 111 and covers the lower oil port 118. The heating element 200 is located on the side of the wicking body 300 facing the mounting plane 111, and the heating element 200 is distributed correspondingly to the atomizing groove 116.

[0042] The bracket 100 with the atomizing core 400 installed is mounted on the oil cup 700. The oil cup 700 is provided with an air outlet channel 710 communicating with the atomization channel 115. The oil cup 700 also has an oil storage chamber 720 communicating with the oil inlet channel 117. The air outlet channel 710 and the oil storage chamber 720 are independent of each other. The atomization channel 115 also includes a connecting channel provided in the support 110. One end of the connecting channel communicates with the atomization slot 116, and the other end communicates with the air outlet channel 710, so that the atomization channel 115 and the air outlet channel 710 are connected.

[0043] The support 110 is also provided with a ventilation channel. One end of the ventilation channel is connected to the atomizing tank 116, and the other end extends out of the bottom of the support 110 and connects to the outside of the oil cup 700. The top of the air outlet channel 710 also extends out of the oil cup 700 and connects to the outside. The ventilation channel, atomizing tank 116, connecting channel (atomizing channel 115), and air outlet channel 710 form the gas flow path. The support 110 is also equipped with two electrodes 800, which are respectively connected to both sides of the heating element 200. The power supply device is electrically connected to the heating element 200 through the electrodes 800, so that current can be provided to the heating element 200 through the electrodes 800.

[0044] The atomizing medium in the oil storage chamber 720 enters the oil guide body 300 through the oil inlet channel 117 and the oil outlet 118. The atomizing medium permeates the oil guide body 300 and comes into contact with the heating element 200. When an electric current is applied to the heating element 200, the atomizing medium is heated to achieve atomization. The atomized gas is dispersed in the atomization tank 116 and, with the user's inhalation action, passes through the atomization channel 115 and the exhaust channel 710 in sequence before entering the user's mouth.

[0045] Since the atomizing tank 116 and the lower oil port 118 are located on the same side, the oil inlet route is as follows: the atomizing medium enters the oil guide body 300 from the oil inlet channel 117 through the lower oil port 118, and then the atomizing medium in the oil guide body 300 penetrates to the position that contacts the heating element 200 and then contacts the heating element 200. Compared with the conventional oil inlet route where the lower oil port 118 is located on the side of the oil guide body 300 away from the heating element 200, the advantages of this oil inlet route are as follows:

[0046] 1. Atomizers can be designed to be smaller in size.

[0047] Reference Figure 3-4 With the dimensions of the wicking body 300, heating element 200, and atomizing channel 115 all being the same, the lower oil inlet 118 in this design is located on one side of the atomizing channel 115. The space occupied by the oil inlet channel 117 largely overlaps with the area of ​​the atomizing channel 115 in the horizontal direction. Moreover, the lower oil inlet 118 falls within the coverage area of ​​the wicking body 300 and does not occupy surrounding space. In contrast, a conventional lower oil inlet 118 is located on the back of the wicking body 300, requiring additional space for the oil hole during design. Comparing the two, the structural design of this design is naturally more compact and saves space.

[0048] 2. The atomizer has a better leak-proof effect.

[0049] In conventional designs, the inlet 118 is located behind the wicking body 300, with the atomizing medium flowing directly through the wicking body 300 to the heating element 200. However, in this design, the inlet 118 is located on both sides of the atomization groove 116, meaning it permeates from both sides of the wicking body 300 into the heating area of ​​the central heating element 200. In electronic atomizer designs, the thickness of the wicking body 300 is significantly smaller than its width. This means that for the same wicking body 300, the wicking path in this design is longer than in a conventional design. A longer wicking path means that the wicking body 300 can store more atomizing medium. There is also a larger buffer space for leakage between the inlet 118 and the heating area of ​​the heating element 200.

[0050] The thickness of the oil guide 300 affects the penetration rate of the atomizing medium, mainly due to the following physical principles:

[0051] 1.) Weakened capillary action

[0052] The oil guide 300 relies on the capillary pores between fibers to adsorb the atomizing medium liquid. As the thickness increases, the atomizing medium needs to travel a longer path to penetrate, and the driving force of capillary action (surface tension) needs to overcome greater gravitational resistance. If the thickness exceeds a critical value, the capillary force may not be sufficient to continuously push the oil upwards or to the other end.

[0053] 2.) Extended penetration path

[0054] According to Darcy's Law, the permeation rate of a fluid in a porous medium is directly proportional to the pressure gradient and inversely proportional to the path length. Increased thickness means a longer path, resulting in a lower oil flow rate and reduced permeation efficiency for the same pressure difference.

[0055] 3.) Accumulated pore resistance

[0056] The thicker oil guide body 300 may have more tortuous or narrow channels within its internal pores. The frictional resistance (viscous resistance) between oil molecules and fibers in the atomizing medium increases with thickness, leading to a decrease in overall permeability. If the oil guide body 300 is over-compacted, resulting in a reduction in porosity, it will further hinder permeation.

[0057] 4.) Gas exhaust problem

[0058] During atomization, air needs to be expelled from the gaps within the wicking body 300. An excessively thick wicking body 300 may trap air, creating air resistance, especially noticeable in high-viscosity oils, thus slowing down oil penetration. Simultaneously, a quality indicator for atomizers is their leak-proof performance under high and low temperature shock tests. Tests have shown that a larger buffer zone within the wicking body 300 from the inlet 118 to the heating element 200 (heating area) results in a larger oil reservoir and better leak-proof performance. The test results are consistent with the above physical principles. Therefore, this design significantly improves the leak-proof quality of the atomizer.

[0059] 3. Atomizers offer better flavor reproduction.

[0060] As can be seen from point 2, the conventionally designed lower oil inlet 118 is closer to the heating area of ​​the heating element 200. The heating area of ​​the heating element 200 has a high atomization temperature, which is quickly transferred to the atomizing medium in the lower oil inlet 118 through the oil guide 300. This heat is further transferred to the atomizing medium inside the oil cup 700. During repeated vaping, the atomizing medium inside the oil cup 700 is repeatedly heated by this high temperature.

[0061] Flavor components, such as fragrances, in the atomizing medium are prone to volatilization when repeatedly heated to high temperatures. Unlike liquids, fragrance molecules are very small and can evaporate through the seams between the atomizer parts. Even in areas where liquids can be sealed, the fragrance can still evaporate. This is why many atomizers experience a significant decrease in flavor and aroma in the latter half of the vaping experience.

[0062] Furthermore, the lower oil inlet 118 of this design is further away from the heating area, making it less likely for high temperatures to reach the lower oil inlet 118. Additionally, the atomizing medium within the oil cup 700 is subjected to significantly less repeated heating, effectively maintaining the stability of the flavorings within the e-liquid. Even when the atomizer is fully inhaled, it maintains excellent flavor and taste fidelity.

[0063] Reference Figure 1-7A sealing gasket 500 is provided between the atomizing core 400 and the mounting surface 111, and the sealing gasket 500 is clamped between the oil guide body 300 and the mounting surface 111. The sealing gasket 500 is a silicone sheet, and the sealing gasket 500 and the silicone body 120 are integrally structured. The sealing gasket 500 covers the lower oil outlet 118, and the sealing gasket 500 has a notch 510 at the position corresponding to the lower oil outlet 118, so that the atomizing medium coming out of the lower oil outlet 118 can flow into the oil guide body 300 through the notch. The sealing gasket 500 can seal the gap between the support 110 (i.e., the outer periphery of the lower oil outlet) and the oil guide body 300, ensuring that the atomizing medium will not seep out from the gap between the two, but can only seep into the oil guide body 300. The support 110 is made of hard plastic or ceramic material, and the sealing gasket 500 can buffer the relative movement between the support 110 and the oil guide body 300, so that neither is easily damaged by force. Specifically, the sealing gasket 500 can be a flat sheet structure.

[0064] In other embodiments, the sealing gasket 500 and the silicone body 120 can also be separate components. When the support 100 is not equipped with the silicone body 120, the sealing gasket 500 is also provided separately. In other embodiments, the sealing gasket 500 can also be a cotton pad. When the sealing gasket 500 is a cotton pad, the cotton pad covers the entire lower oil port 118, and the cotton pad may or may not have a notch 510. When the cotton pad, which serves as the sealing gasket 500, does not have a notch 510, the oil inlet channel 117 permeates into the oil guide body 300 through the lower oil port, and the cotton pad has a certain absorption rate for the atomizing medium, which can effectively prevent the atomizing medium from flowing out from the gap between the support 110 and the oil guide body 300. At the same time, the cotton pad can also buffer the relative movement between the support 110 and the oil guide body 300, making both less prone to breakage under stress.

[0065] A return air channel is formed between the mounting surface 111 and the sealing gasket 500. The return air channel includes an exhaust port 113 and an exhaust groove 114, both of which are located on the mounting surface 111. The exhaust port 113 is connected to the oil inlet channel 117, and the exhaust port 113 is spaced apart from the lower oil port 118. One end of the exhaust groove 114 is connected to the exhaust port 113, and the other end is connected to the atomizing groove 116, thereby balancing the air pressure in the oil storage chamber 720.

[0066] The support 110 is also covered by a fastener 600, which is made of food-grade hard metal. After the silicone body 120, the sealing gasket 500, and the atomizing core 400 are installed on the mounting surface 111, the fastener 600 covers the mounting surface 111, thereby restricting the position of the sealing gasket 500 and the atomizing core 400 and facilitating assembly. Furthermore, both sides of the support 110 are provided with buckles 610, and both sides of the fastener 600 are provided with slots 620. The buckles 610 and slots 620 are matched and engaged to connect the fastener 600 to the support 110. In other embodiments, the support 110 may have slots 620 on both sides, and the fastener 600 may have buckles 610 on both sides. In other embodiments, the fastener 600 may also be fitted with screws, which are threaded into the support 110, thereby achieving a detachable connection between the fastener 600 and the support 110.

[0067] It should be noted that in this embodiment, there are two oil inlets 118, distributed on both sides of the atomizing groove 116, which can balance the oil supply. In other embodiments, if the shape of other components restricts the application, one or more oil inlets 118 may be provided.

[0068] In some specific embodiments, the sealing gasket 500 is at least partially disposed around the outer periphery of the atomizing groove 116 on the mounting plane 111 to seal the connection gap between the rigid oil guide 300 and the mounting plane 111, so as to prevent the aerosol formed by atomization from overflowing outward through the connection gap between the rigid oil guide 300 and the mounting plane 111.

[0069] Example 2:

[0070] Reference Figure 8 The difference between this embodiment and Embodiment 1 is that: the mounting plane 111 is provided with a protrusion 112, the notch 510 on the sealing gasket 500 corresponds to the protrusion 112, and the protrusion 112 passes through the notch 510, with the lower oil port 118 disposed in the protrusion 112. Along the direction perpendicular to the mounting plane 111, the protrusion height of the protrusion 112 is lower than the thickness of the sealing gasket 500, so that the protrusion 112 does not contact the oil guide body 300, but the atomizing medium flowing out from the lower oil port 118 can directly penetrate into the oil guide body 300.

[0071] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
