Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and more particularly to an atomizer and its electronic atomization device. Background Technology

[0002] Currently, in the field of electronic atomization technology, when the wicking cotton guides the e-liquid in the oil reservoir from the oil inlet to the atomizer head in the atomization chamber, there is a lack of effective control over the e-liquid flow rate. Initially, the flow rate is slow, causing the atomizer head to fail to atomize at the beginning. After the atomizer has been working for a period of time, the e-liquid flow rate increases, but the atomization speed of the atomizer head cannot keep up with the flow rate, resulting in excess e-liquid accumulating on the atomizer head and easily causing spitting.

[0003] There are two types of atomizer heads: electric atomizer heads and ultrasonic atomizer heads. Ultrasonic atomizers work by mechanically converting e-liquid from a liquid to a gaseous state, which is fundamentally different from coil atomization. The former simply uses high-frequency vibration to atomize the e-liquid, while the latter vaporizes it by increasing the temperature. The former is more environmentally friendly and healthier, with an operating temperature not exceeding 150℃. The latter typically operates between 200℃ and 300℃. Electric atomizer heads vibrate without e-liquid, while ultrasonic atomizer heads dry-burn when there is insufficient e-liquid, causing the release of harmful substances. Therefore, ultrasonic atomization is highly favored in the market.

[0004] However, ultrasonic atomizers operate on a single plane, a significant difference from traditional heating coils. Therefore, their e-liquid supply requires guiding the e-liquid through a wicking element to the working surface of the atomizer. The atomizer works normally under load, but vibrates without load, causing damage. Currently, the common practice is to guide the e-liquid into the atomizer's plane using a wicking element, and then add a spring to prevent vibrations from pushing the wicking element away, ensuring flexible contact between the e-liquid and the atomizer. Atomizers with this structure generally have the following problems:

[0005] 1. No smoke on the first few puffs and slow vapor production. Because the wicking material is connected to the atomizer head via a bridging mechanism, it lacks control over the e-liquid's retention function. This results in excessive e-liquid buildup on the atomizer head after prolonged periods of inactivity, preventing the atomizer from vaporizing when it starts working.

[0006] 2. Prolonged use may cause hot e-liquid to spray up. The reason is the same as above: because the entry and exit of e-liquid is not controlled, the temperature rises when the atomizer head is working, causing the e-liquid to flow faster. Too much e-liquid on the surface of the atomizer head will cause splattering.

[0007] 3. The main unit will get hot after prolonged use. The ultrasonic atomizer works by vibrating at a high frequency (3 MHz), which generates heat. If heat dissipation and insulation are not done, the heat will accumulate in the atomizer and then be transferred to the main unit through the electrodes, causing the motherboard to overheat and easily damaging electronic components.

[0008] 4. Backflowing oil will drip onto the atomizer head, causing unstable operating temperature and vapor production, affecting the user experience.

[0009] 5. Frequent low oil alarm. Due to poor oil supply control by the oil guide, the oil supply is inconsistent. When the oil supply is insufficient, the circuit will automatically activate a protection alarm and shut down, affecting the user experience. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0060] refer to Figure 1An atomizer includes: a base 500, a first housing 100 and a second housing 400 disposed on the base 500, the second housing 400 being located inside the first housing 100, a cavity between the first housing 100 and the second housing 400 forming an oil storage chamber 10, and a cavity enclosed by the second housing forming an atomization chamber 20. At least one oil inlet 401 is provided on the side wall of the second housing 400. An oil control component 300 and an atomizing head 700 are disposed within the atomization chamber 20. The upper end of the oil control component 300 is connected to the oil inlet 401, and the lower end is connected to the upper surface of the atomizing head. The oil control component 300 controls the flow rate of e-liquid flowing from the oil inlet 401 to the atomizing head 700. Specifically, the flow rate of e-liquid (not shown) in the oil storage chamber 10 from the oil inlet 401 to the atomizing head 700 via the oil control component 300 can be adjusted by regulating the oil control component. For example, when the atomizer is first used, because there is relatively little e-liquid flowing onto the atomizer head 700, the wicking speed of the wicking component 300 needs to be increased to prevent the atomizer head 700 from dry-burning due to insufficient e-liquid, thus avoiding a lack of vapor or slow vapor production in the first few puffs. When the atomizer is used for an extended period, the e-liquid temperature in the reservoir is higher, and the e-liquid flow rate is faster. The e-liquid flows quickly from the inlet 401 through the wicking component 300 to the atomizer head 700, resulting in a large amount of e-liquid on the atomizer head 700. The atomizer head 700 cannot atomize this accumulated e-liquid into vapor in a short time, leading to excessive e-liquid accumulation and spitting. In this case, adjusting the wicking component 300 slows down the flow rate of e-liquid from the inlet 401 to the atomizer head 700, reducing the amount of e-liquid accumulating on the atomizer head and minimizing spitting. The atomizing head 700 mentioned above can be an electrically heated atomizing head or an ultrasonic atomizing head. The oil control component 300 adjusts the flow rate of e-liquid from the oil inlet to the atomizing head 700 to achieve a stable oil supply and prevent the atomizing head from failing to atomize at the start of operation and from spitting oil after a period of use. This application merely exemplifies the scenario where the atomizing head 700 is an ultrasonic atomizing head.

[0061] exist Figure 1In this design, when the atomizer head 700 is an ultrasonic atomizer head, a vibration damping block 800 is also installed in the atomization chamber at the lower end of the ultrasonic atomizer head. The upper end of the ultrasonic atomizer head contacts the oil control component 300, and the lower end contacts the vibration damping block 800. The oil control component 300 supplies the e-liquid flowing out of the oil inlet 401 to the ultrasonic atomizer head as needed, and the ultrasonic atomizer head atomizes the e-liquid into vapor. The "on demand" aspect refers to the adjustable flow rate of the e-liquid from the reservoir chamber after flowing out of the oil inlet 401 and being guided to the ultrasonic atomizer head by the oil control component 300. For example, when the atomizer is first used, the oil guiding speed is relatively slow. At this time, the oil guiding speed needs to be increased by the oil control component 300 to prevent the ultrasonic atomizer head from vibrating empty due to a lack of e-liquid, thus avoiding a lack of vapor or slow vapor production in the first few puffs. When the atomizer is used for a long time, the e-liquid temperature in the reservoir is high and the e-liquid flow rate is fast. As a result, the e-liquid flowing out of the inlet 401 and guided to the ultrasonic atomizing head by the oil control component 300 flows at a fast speed. In a short period of time, a relatively large amount of e-liquid will remain on the ultrasonic atomizing head. Since the vibration frequency of the ultrasonic atomizing head is preset, a large amount of e-liquid will not be vibrated into atomized vapor in a short time. This will result in too much e-liquid on the atomizing head surface of the ultrasonic atomizing head, causing spitting. At this time, by adjusting the oil control component 300, the flow rate of e-liquid flowing out of the inlet 401 and guided to the ultrasonic atomizing head by the oil control component 300 is reduced, thus reducing the occurrence of spitting caused by too much e-liquid remaining on the ultrasonic atomizing head.

[0062] Example 1

[0063] refer to Figure 3 An atomizer includes: a first housing 100, a pressing assembly 200, an oil control assembly 300, a second housing 400, and a base 500. In this embodiment, the first housing 100 is approximately W-shaped and rests on the base 500, but there are gaps on the left and right sides of the middle of the first housing 100, and the lower middle part does not contact the base 500. The second housing 400 is a hollow cylinder, with its lower end located in the middle of the base 500, and its upper end connected to the unclosed end of the first housing 100 via a connector 600; that is, the connector 600 connects the first housing 100 and the second housing 400 together. Figure 3As can be seen, the space inside the second housing 400 forms an atomizing chamber; the closed cavity formed by the first housing 100, connector 600, clamping assembly 200, second housing 400, and base 500 is an oil storage chamber. The clamping assembly 200 is connected to the upper end of the inner wall of the second housing 400, and the oil control assembly 300 is disposed on the inner wall of the second housing 400 and located at the lower end of the clamping assembly 200. At the lower end of the oil control assembly 300 is the atomizing head 700, and a vibration damping block 800 is provided on the lower end face of the ultrasonic atomizing head. It can be understood that the atomizing head is located inside the atomizing chamber, that is, inside the second housing 400. Figure 3 In the second housing 400, at least one oil inlet 401 is provided on the upper side wall. It is understood that the oil control assembly 300 connects the oil inlet 401 and the atomizer head. As mentioned earlier, the oil control assembly 300 can control the speed at which oil flows from the oil inlet 401 into the atomizer head as needed. The specific reasons have been analyzed previously and will not be repeated here. For example, when the atomizer is first used, because the e-liquid in the reservoir is at a low temperature and has high viscosity, the e-liquid flows slowly from the oil inlet 401 to the atomizer head through the oil control assembly 300. To improve the oil guiding speed, the oil control assembly 300 needs to ensure that the e-liquid in the oil inlet 401 flows quickly to the atomizer head, so that the atomizer head does not vibrate empty due to a lack of e-liquid, thus avoiding a lack of vapor or slow vapor production in the first few puffs. After prolonged use of the atomizer, the e-liquid temperature in the reservoir is high, and the e-liquid flows quickly. A significant amount of e-liquid flows through the inlet 401 and the control assembly 300 to the atomizer head, resulting in faster e-liquid flow. Since the ultrasonic atomizer head's vibration frequency is preset, it won't atomize a large amount of e-liquid within a short time, thus preventing excessive e-liquid buildup on the atomizer head 700 surface and causing spitting. To prevent spitting, the control assembly 300 directs the e-liquid out of the inlet 401 and reduces the flow rate to the ultrasonic atomizer head.

[0064] refer to Figure 3 In Embodiment 1, the oil control assembly 300 includes a first oil guide body 301, a pressure mesh 302, and a second oil guide body 303 arranged sequentially from top to bottom. The first oil guide body 301 is a hollow first annular block, with its upper end abutting against the pressing assembly 200, its lower end contacting the upper surface of the pressure mesh 302, and the lower surface of the pressure mesh 302 contacting the atomizing head 700. (Reference) Figure 5The first wicking body 301 is a hollow annular block, preferably made of cotton. The tightness and amount of cotton are adjustable. For example, in the initial stage of atomizer use, the cotton is set looser, so that the e-liquid flowing out of the inlet 401 is quickly guided by the first wicking body 301 to the pressure screen 302, then through the pressure screen 302 to the second wicking body 303, and then to the atomizer head 700. In the middle stage of use, because the e-liquid temperature increases and the e-liquid flow rate increases, the cotton is set tighter to reduce the wicking speed.

[0065] Figure 3 In order to improve the e-liquid guiding speed and shorten the e-liquid guiding path, the cotton fibers of the first e-liquid guide body 301 are set vertically downward to maintain the same direction as the e-liquid guiding direction. The second e-liquid guide body 303 is preferably flat, and its material is preferably aramid, because aramid has high strength and is not easily damaged under the high-intensity vibration of the atomizer head 700. The second e-liquid guide body 303 can also be made of other materials with a certain strength besides aramid, which is not limited here. It can be understood that when the material of the second e-liquid guide body 303 is aramid, its fiber distribution direction is also vertically downward, which shortens the e-liquid guiding path to the atomizer head 700 and speeds up the e-liquid guiding speed. In this embodiment, during the vibration of the ultrasonic atomizer head, the pressure mesh 302 covers the second e-liquid guide body 303 to reduce the damage to the first e-liquid guide body 301 caused by the vibration of the second e-liquid guide body 303. The pressure mesh 302 is an elastic pressure mesh with a certain degree of unevenness, made of metal or non-metal. The mesh density is optimal so as not to obstruct the flow of smoke. In this embodiment, the mesh density of the pressure mesh is preferably 20 mesh, but this is only an example. The mesh density can be adjusted as needed, for example, it can be 30 mesh, 40 mesh or 15 mesh.

[0066] In summary, this embodiment can regulate the speed at which e-liquid flows from the oil inlet 401 into the ultrasonic atomizing head, reducing the occurrence of no smoke or vapor or slow smoke generation in the first few puffs when smoking, and also reducing the occurrence of oil splattering.

[0067] Figure 3 In this embodiment, when the atomizing head 700 is an ultrasonic atomizing head, a vibration damping block 800 is also required. If the atomizing head 700 is an electrically heated atomizing head, then a vibration damping module is not needed. The vibration damping block 800 is located at the lower end of the ultrasonic atomizing head 701, which can reduce the impact of the ultrasonic atomizing head vibration on other components in the atomizer. The vibration damping block 800 is made of a material with vibration damping effect, such as PE, adhesive non-woven fabric, silicone, etc., without limitation. In this embodiment, silicone is preferred because silicone has good vibration damping properties.

[0068] refer to Figure 3An electrode assembly is located at the lower end of the vibration damping block 800. This assembly is electrically connected to and provides power to the ultrasonic atomizing head 701. The electrode assembly includes a positive electrode post 803 and a negative electrode post 802. The negative electrode post 802 is a hollow ring. The positive electrode post 803 is positioned in the middle of the stack formed by the vibration damping block 800, the circuit board 801, and the negative electrode post 802. The circuit board 801 is located between the vibration damping block 800 and the negative electrode post 802, and it functions to control the normal operation of each functional module in the atomizer. A conductor 804 is placed on the positive electrode post 803. The upper end of the conductor 804 is connected to the ultrasonic atomizing head, and the lower end is connected to the upper end of the positive electrode post 803. The upper end of the positive electrode post 803 is electrically connected to the ultrasonic atomizing head 701 via the conductor 804, while the lower end rests on and is electrically connected to the base 500. The bottom end of the negative electrode post 802 is mounted on the base 500 and electrically connected to the base 500, while the outer side wall is electrically connected to the ultrasonic atomizing head 701 through the second housing 400.

[0069] The positive electrode post 803 consists of several cylindrical segments with progressively decreasing outer diameters, with the uppermost segment having the largest outer diameter. This structural design reduces heat transfer to the battery, thus improving battery lifespan. The conductor 804 can be a wire, a metal sheet, or a vibration-damping spring. If a vibration-damping spring is chosen, it can function as both a vibration damper and a wire.

[0070] refer to Figure 3 and Figure 6 The clamping assembly 200 includes a clamping device 201 disposed on the inner side of the upper end of the second housing 400, a first sealing member 202 disposed on the outer side of the clamping device 201, a third housing 203 disposed on the outer side of the first sealing member 202, and a second sealing member 204 disposed between the third housing 203 and the first housing 100. Both the first sealing member 202 and the second sealing member 204 serve a sealing function, separating the atomizing chamber and the oil storage chamber. The first sealing member 202 and the second sealing member 204 are preferably made of silicone.

[0071] refer to Figure 3 and Figure 6 , Figure 6 for Figure 3 A partial enlarged view at point C shows that the main body of the clamping device 201 is a hollow cylinder 2010. A liquid collection groove 2011 is provided on the outer wall of the cylinder 2010. A support block 2012 extends horizontally outward from the outer side of the liquid collection groove. On the outer side of each support block 2010, a hook 2013 is provided. The two hooks 2013 are engaged with the first through hole 402 of the second housing 400 (see...). Figure 5 and Figure 6 On the upper end of the cylinder 2010, a first chamfer 2014 is provided on the outer wall. Preferably, on the upper end of the cylinder 2010, a first chamfer 2014 is provided on the outer wall. Figure 6 In the design, a second chamfer 101 is formed on the inner wall at the junction of the first housing 100 and the third housing 203. At the junction of the first housing 100 and the third housing 203, there is a gap between the first chamfer 2014 and the junction, which serves as part of a channel for the condensation and return of atomized vapor to the collection tank 2011. (Reference) Figure 6 As the atomized vapor (not shown) rises along the arrow, it is condensed and liquefied to form e-liquid droplets. These droplets flow downwards along the outer wall of the first housing 100, which serves as the atomizing chamber, to the second chamfer 101. Due to the low viscosity and density of the e-liquid droplets, they do not fall vertically at the first chamfer 2014, but instead fall vertically along the inclined wall of the second chamfer 101 onto the first chamfer 2014, and then flow along the first chamfer 2014 into the collection tank 2011.

[0072] Preferably, setting the first chamfer 2014 as a right angle and the second chamfer 101 as a rounded corner can better achieve the effect of condensation and reflux of atomized steam.

[0073] If the first chamfer 2014 and the second chamfer 101 are not present, the upper middle part of the cylinder 2010 can be set as an inwardly concave, roughly "V"-shaped structure (see...). Figure 3 , Figure 6 , Figure 7 and Figure 8 This also achieves the purpose of collecting condensed e-liquid in the collection tank 2011, because: (Refer to...) Figure 6 As the atomized vapor (not shown) rises along the arrow, it is condensed and liquefied to form e-liquid droplets. These droplets flow downwards along the outer wall of the first housing 100, which serves as the atomizing chamber, directly to the outer wall of the cylinder 2010, and then into the collection tank 2011. Therefore, in this application, as long as the upper middle part of the cylinder 2010 is configured as an inwardly concave, roughly "V"-shaped structure, the first chamfer 2014 and the second chamfer 101 are not necessary.

[0074] refer to Figure 3 and Figure 5 A fixing bracket 403 is provided between the first housing 100 and the second housing 400, and a third sealing element 404 is provided on the upper end face of the fixing bracket 403. The fixing bracket 403 is detachably connected to the first housing 100. The fixing bracket 403 together with the third sealing element 404 forms the bottom of the oil storage cavity.

[0075] from Figure 3 It can be seen that the first seal 202, the second seal 204 and the third seal 404 all serve to seal the e-liquid in the oil storage chamber to prevent the e-liquid from seeping into other parts of the atomizer.

[0076] refer to Figure 5 At least one second through hole 501 is also provided on the base 500. (Reference) Figure 4 The second through-hole 501 is used for external air to enter the atomizer. The air intake passage passes around the second housing, which can carry away the heat accumulated in the atomizer head, reduce the temperature of the atomizer head, and ensure that the atomizer head works normally, reducing the risk of overheating alarms and shutdowns.

[0077] Example 2

[0078] refer to Figure 7 and Figure 8 Unlike Embodiment 1, in this embodiment, the oil control component 300 is no longer composed of... Figure 3 The device 200 consists of a first oil guide body 301, a pressure mesh 302, and a second oil guide body 303 arranged sequentially from top to bottom. Instead, it forms an annular groove structure with a third oil guide body 304. The annular upper surface of the third oil guide body 304 abuts against the lower ends of the two support blocks 2012 of the pressing device 201, and the upper surface of the concave horizontal portion of the third oil guide body 304 abuts against the lower end surface of the cylinder 2010 of the pressing device 201. (Reference) Figure 8 , Figure 9 and Figure 10 , Figure 7 This is a cross-sectional view of the second embodiment. Figure 8 for Figure 7 A magnified view of a portion at point D. Figure 9 This is an exploded view of the second embodiment. Figure 10 for Figure 9 Enlarged view of the intermediate pressing device 201. The material of the third oil guide body 304 is a blended fabric, preferably composed of 10-40% cotton and 60-90% aramid by mass percentage. Because the material of the third oil guide body 304 is a blended fabric, it presses against the ultrasonic atomizing head 701 under the compression of the pressing device 201 to ensure that the ultrasonic atomizing head 701 is not damaged by vibration. Because the air permeability of the blended fabric is relatively poor, the air inlet 2015 must be opened on the side wall of the lower end of the cylinder 2010 (see...). Figure 10 ),but Figure 11 After entering through the second through-hole 501, the external air finally passes through the side wall of the lower end of the cylinder 2010 and enters the atomization chamber.

[0079] It should be noted that the air intake in 2015 is not just like... Figure 10 The notch shown can also be a through hole (not shown) provided on the side wall of the lower end of the cylinder 2010.

[0080] When the atomizer is first used, the e-liquid in the reservoir is at a low temperature and has a high viscosity. Therefore, the e-liquid flows slowly from the inlet 401 through the third guide body 304 to the ultrasonic atomizing head. In order to increase the guiding speed, the third guide body 304 needs to allow the e-liquid in the inlet 401 to flow quickly to the ultrasonic atomizing head. Therefore, the third guide body 304 needs to be adjusted to be more fluffy, thus increasing the guiding speed. After prolonged use of the atomizer, the e-liquid temperature rises due to the heat generated by the vibration of the ultrasonic atomizing head, resulting in a faster e-liquid flow rate. Consequently, a larger amount of e-liquid flows through the inlet 401 and the third wicking body 304 to the ultrasonic atomizing head. Since the vibration frequency of the ultrasonic atomizing head is preset, it cannot atomize a large amount of e-liquid into vapor in a short time, leading to excessive e-liquid accumulation on the ultrasonic atomizing head and causing spitting. To reduce spitting, the third wicking body 304 needs to control the flow rate of e-liquid from the inlet 401 to the ultrasonic atomizing head, thus reducing spitting. This is achieved by compressing the third wicking body 304, slowing its flow rate and minimizing spitting. In this embodiment, the third wicking body 304 is the aforementioned blended material.

[0081] Table 1 shows the relationship between the percentage of cotton and aramid fibers in the blended fabric and the amount of e-liquid used.

[0082] Table 1

[0083]

[0084]

[0085] As shown in Table 1, when the mass ratio of aramid to cotton in the blend is close, the e-liquid consumption is the highest, indicating the best wicking effect. While the wicking effect is good when the blend is entirely cotton, the material deteriorates quickly, resulting in relatively low e-liquid consumption. Similarly, while the blend has high strength, its poor wicking performance also leads to low e-liquid consumption. The table also shows that the optimal wicking effect is achieved when both aramid and cotton have a 50% mass percentage, and the blend also exhibits a relatively high wicking efficiency.

[0086] It should be noted that the atomizing head 700 in this application can be either an electric heating atomizing head or an ultrasonic atomizing head. If it is an electric heating atomizing head, the vibration damping block 800 is not required. If it is an ultrasonic atomizing head, the vibration damping block 800 is required to reduce the damage to other components of the atomizer caused by the vibration of the ultrasonic atomizing head during operation. The accompanying drawings provided in this application ( Figure 1 Except for the case where the atomizing head 700 is an ultrasonic atomizing head 701, the above only refers to the case where the atomizing head 700 is an ultrasonic atomizing head 701.

[0087] The present invention also discloses an electronic atomizing device (not shown), which includes the aforementioned atomizer. It is understood that this electronic atomizing device also possesses the advantages of the atomizer.

[0088] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
