Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomizers, and in particular to a disc-type atomization heating structure and an electronic atomization device. Background Art

[0002] Electronic cigarettes, also known as virtual cigarettes and electronic cigarettes, have the same appearance as cigarettes, similar taste to cigarettes, and even have many more flavors than ordinary cigarettes. They can also inhale smoke, taste and feel like cigarettes. They are mainly used to quit smoking and replace cigarettes. Electronic cigarettes are also a non-combustion tobacco substitute product. They are similar to some characteristics of ordinary cigarettes, which can refresh smokers and satisfy their pleasure and the habit of using them for many years. But they are essentially different from ordinary cigarettes. Electronic cigarettes do not burn, do not contain tar, and do not contain more than 460 chemical substances that cause respiratory and cardiovascular diseases when ordinary cigarettes are burned, thereby removing carcinogens in ordinary cigarettes, and will not cause "second-hand smoke" hazards to others and pollute the environment. The heating wire in the traditional atomizer is used to heat the atomizing cotton or atomizing ceramics. The heating wire is usually fixed by winding or embedding. The shape of the heating wire is usually spring-shaped, so that the atomizing cotton or atomizing ceramics can be heated at the same time to achieve a uniform heating effect.

[0003] However, in order to ensure better heating uniformity of the atomized cotton or atomized ceramics, the overall length of the traditional heating wire is longer, that is, the number of contact points with the atomized cotton or atomized ceramics increases, which increases the production cost of the heating wire and thus increases the manufacturing cost of the atomizer. Moreover, the increased volume of the atomized cotton or atomized ceramics is also likely to lead to an increase in the manufacturing cost of the atomizer. Summary of the invention

[0028] The present invention relates to a disc-type atomizing heating structure. In one embodiment, the disc-type atomizing heating structure is used to be sleeved in a packaging sleeve, and includes: an atomizing heat conductor and a disc-type heating element; the atomizing heat conductor abuts against the inner wall of the packaging sleeve, and the atomizing heat conductor is provided with a central air hole, and the central air hole is used to conduct airflow; part of the disc-type heating element has a planar thread structure, and at least part of the planar thread structure of the disc-type heating element is connected to the atomizing heat conductor, and the disc-type heating element is used to be electrically connected to a battery to heat the atomizing heat conductor. Since the area where the disc-type heating element is connected to the atomizing heat conductor is a planar thread structure, that is, this part of the disc-type heating element is in the same plane and is threadedly distributed, after the disc-type heating element is energized, the thread distribution structure ensures the uniformity of the heating of the atomizing heat conductor, and the part of the disc-type heating element used to heat the atomizing heat conductor is located in the same plane, so that the material used for the disc-type heating element is reduced, thereby reducing the production cost of the disc-type atomizing heating structure.

[0029] See also Figure 1 , which is a schematic structural diagram of a disc-type atomizing heating structure according to an embodiment of the present invention.

[0030] The disc-type atomizing heating structure 10 of one embodiment is used to be set in the packaging sleeve, including an atomizing heat conductor 100 and a disc-type heating element 200; the atomizing heat conductor 100 is in contact with the inner wall of the packaging sleeve, please refer to Figure 2 The atomizing heat conductor 100 is provided with a central air hole 102, and the central air hole 102 is used to conduct air flow; part of the disc-type heating element 200 has a planar thread structure, and at least part of the planar thread structure of the disc-type heating element 200 is connected to the atomizing heat conductor 100, and the disc-type heating element 200 is used to be electrically connected to a battery to heat the atomizing heat conductor 100.

[0031] In this embodiment, since the area where the disc heating element 200 is connected to the atomizing heat conductor 100 is a planar threaded structure, that is, this part of the disc heating element 200 is in the same plane and is threadedly distributed, after the disc heating element 200 is energized, the threaded distribution structure ensures the uniformity of heating of the atomizing heat conductor 100, and the part of the disc heating element 200 used to heat the atomizing heat conductor 100 is located in the same plane, so that the material used for the disc heating element 200 is reduced, thereby reducing the production cost of the disc atomizing heating structure.

[0032] In one embodiment, see Figure 2 The disc-type heating element 200 includes a disc-type threaded portion 210 and a conductive pin portion 220 that are connected to each other. The disc-type threaded portion 210 is connected to the atomizing heat conductor 100, and the disc-type threaded portion 210 is used to heat the atomizing heat conductor 100. The conductive pin portion 220 is connected to a battery. In this embodiment, the planar thread structure in the disc-type heating element 200 is the disc-type threaded portion 210. The disc-type threaded portion 210 itself has a spiral shape, and is a spiral on a plane. For example, the disc-type threaded portion 210 presents a mosquito coil-type structure, so that the disc-type threaded portion 210 is spirally distributed on the same plane, so that a spiral ring with a gradually increasing diameter and continuous is distributed on a plane. The conductive pin portion 220 is connected to the disc-type threaded portion 210, and the conductive pin portion 220 guides the current output by the battery to the disc-type threaded portion 210, so that the heat on the atomizing heat conductor 100 connected to the disc-type threaded portion 210 is evenly distributed, thereby improving the heating uniformity of the atomizing heat conductor 100. In another embodiment, the disc-type threaded portion 210 is embedded in the atomizing heat conductor 100, and when the disc-type threaded portion 210 is embedded in the atomizing heat conductor 100, the disc-type threaded portion 210 is completely wrapped by the atomizing heat conductor 100, thereby increasing the contact area between the disc-type threaded portion 210 and the atomizing heat conductor 100, further improving the heating uniformity of the atomizing heat conductor 100. Moreover, in the present embodiment, the structure of the atomizing heat conductor 100 matches the thread structure of the disc-type threaded portion 210. For example, the atomizing heat conductor 100 is a sheet-like structure, so that the plane where the thread structure of the disc-type threaded portion 210 is located is parallel to the side of the atomizing heat conductor 100, thereby reducing the overall volume of the atomizing heat conductor 100. While taking into account the heating uniformity of the atomizing heat conductor 100, the molding material of the atomizing heat conductor 100 is also reduced, thereby reducing the production cost of the disc-type atomizing heating structure.

[0033] In one embodiment, see Figure 2The disc-type atomizing heating structure 10 also includes an oil locking member 300, which is connected to the atomizing heat conductor 100. The atomizing heat conductor 100 is provided with an oil injection hole 104, which is arranged corresponding to the oil locking member 300. The oil injection hole 104 is used to inject smoke oil, and the oil locking member 300 is used to absorb and lock the smoke oil. In this embodiment, the oil locking member 300 is located below the atomizing heat conductor 100, and the oil locking member 300 corresponds to the oil injection hole 104 on the atomizing heat conductor 100. When the smoke oil is injected through the oil injection hole 104, the oil locking member 300 absorbs the smoke oil and stores it therein, effectively limiting the smoke oil in the oil locking member 300, so that the atomizing heat conductor 100 can heat the smoke oil to form smoke.

[0034] For further information, see Figure 2 , the oil lock member 300 has an air outlet channel 302, and the air outlet channel 302 is connected to the central air hole 102. In this embodiment, the oil lock member 300 is connected to the atomizing heat conductor 100, and the atomizing heat conductor 100 heats the tobacco oil on the oil lock member 300 to form smoke. In order to facilitate the extraction of smoke, the air outlet channel 302 of the oil lock member 300 is connected to the central air hole 102 of the atomizing heat conductor 100. For example, the air outlet channel 302 is aligned with the central air hole 102. After the disc-type heating element 200 is powered on, the heat generated on the atomizing heat conductor 100 is used to heat the tobacco oil on the oil lock member 300 into smoke, and then passes through the air outlet channel 302 and the central air hole 102 in sequence, thereby guiding the smoke to the nozzle.

[0035] Further, see Figure 2 The disc-type atomizing heating structure 10 further includes an oil injection seal 400, a portion of which is inserted into the oil injection through hole 104, and the oil injection seal 400 is used to block the oil injection through hole 104 after the smoke oil is injected. In this embodiment, the oil injection through hole 104 provided on the atomizing heat conductor 100 is used to inject smoke oil into the oil locking member 300. After the smoke oil is injected into the oil locking member 300 through the oil injection through hole 104, the oil locking member 300 absorbs and stores the smoke oil. For example, the oil locking member 300 is an oil-absorbing cotton. In order to prevent the smoke oil from flowing back and overflowing through the oil filling hole 104, the oil filling seal 400 is added and part of the oil filling seal 400 is embedded in the oil filling hole 104, so that after the smoke oil is injected, the oil filling hole 104 is blocked by the oil filling seal 400, thereby reducing the probability of the smoke oil on the oil locking member 300 leaking out, so as to improve the anti-leakage sealing performance of the disc-type atomization heating structure.

[0036] Further, see Figure 2 The disc-type atomizing heating structure 10 further includes a nozzle cover 500, the nozzle cover 500 is provided with a nozzle hole 502, the oil injection seal 400 is provided with an air guide hole 402, the nozzle hole 502 and the air guide hole 402 are both connected to the central air hole 102, the oil injection seal 400 is further provided with a clamping groove 404, and a part of the nozzle cover 500 is clamped in the clamping groove 404. In this embodiment, the nozzle cover 500 is sleeved on the oil injection seal 400, and a part of the nozzle cover 500 and the oil injection seal 400 are located in the packaging sleeve, that is, the oil injection seal 400 is completely embedded in the packaging sleeve, and a part of the nozzle cover 500 is embedded in the packaging sleeve. The nozzle cover 500 is used for the user to suck, and the nozzle hole 502 on the nozzle cover 500 corresponds to the air guide hole 402 on the oil filling seal 400, and the nozzle hole 502 and the air guide hole 402 are both connected to the central air hole 102, so that the smoke formed by the smoke oil on the oil locking member 300 passes through the air outlet channel 302, the central air hole 102, the air guide hole 402 and the nozzle hole 502 in sequence, and finally reaches the user's oral cavity through the nozzle hole 502, so that the user can inhale the smoke through the nozzle cover 500.

[0037] In one embodiment, see Figure 2 , the disc-type atomizing heating structure 10 also includes an atomizing base 600, the atomizing base 600 is located on the side of the oil lock 300 away from the atomizing heat conductor 100, the atomizing base 600 is connected to the oil lock 300, and the atomizing base 600 also abuts against the inner wall of the packaging sleeve. In this embodiment, the atomizing base 600 is located at the bottom of the oil lock 300, and the atomizing base 600 and the atomizing heat conductor 100 clamp the oil lock 300, that is, the oil lock 300 is located between the atomizing base 600 and the atomizing heat conductor 100. An oil storage space is formed between the atomizing base 600, the atomizing heat conductor 100 and the packaging sleeve, the oil lock 300 is located in the oil storage space, the atomizing heat conductor 100 abuts against the inner wall of the packaging sleeve, and the atomizing base 600 also abuts against the inner wall of the packaging sleeve, so that the oil storage space is relatively closed. The side of the atomizer base 600 facing away from the oil lock member 300 is close to the battery. Under the obstruction of the atomizer base 600, the smoke oil on the oil lock member 300 is confined within the oil storage space, reducing the probability of the smoke oil on the oil lock member 300 dripping onto the battery, thereby further improving the anti-oil leakage sealing performance of the disc-type atomization heating structure.

[0038] For further information, see Figure 2, the atomizing base 600 is provided with a pin through hole 602, part of the disc-type heating element 200 is penetrated in the pin through hole 602, and the pin through hole 602 is arranged corresponding to the battery, so that the disc-type heating element 200 is connected to the power supply end of the battery. In the present embodiment, the pin through hole 602 is provided on the atomizing base 600, and part of the disc-type heating element 200 is clamped in the pin through hole 602, that is, the pin of the disc-type heating element 200 is located in the pin through hole 602, that is, the conductive pin portion 220 of the disc-type heating element 200 is penetrated in the pin through hole 602, and the pin of the disc-type heating element 200 is connected to the power supply end of the battery, so that the external battery and the disc-type heating element 200 are convenient for supplying power to the disc-type heating element 200, thereby facilitating heating of the atomizing heat conductor 100.

[0039] It can be understood that the disk-type heating element 200 heats the atomizing heat conductor 100 by heating after being powered on, so as to heat the tobacco oil on the oil lock element 300, thereby realizing the atomization of the tobacco oil. In actual use, a large amount of tobacco oil is adsorbed on the oil lock element 300, and the disk-type heating element 200 needs to contact the power supply end of the battery, so the disk-type heating element 200 needs to pass through the oil lock element 300 to connect the disk-type heating element 200 to the battery. Specifically, the conductive pin portion 220 of the disk-type heating element 200 crosses the oil lock element 300. However, during long-term use, the conductive pin portion 220 will inevitably come into contact with the oil locking member 300. Under the action of gravity, part of the smoke oil on the oil locking member 300 will crawl along the surface of the conductive pin portion 220. Eventually, the smoke oil will drip onto the battery under the guidance of the conductive pin portion 220, seriously affecting the surface cleanliness of the battery, and easily causing a large amount of smoke oil to accumulate at the power supply end of the battery and spontaneously combust, resulting in a major safety issue in the use of the disc-type atomization heating structure.

[0040] In order to avoid the above situation, that is, to reduce the probability of the oil on the oil lock 300 dripping onto the battery, please refer to Figure 2 as well as Figure 3The atomizing heat conductor 100 includes a sheet-like heat-conducting body 110 and a drip-proof sealing tube 120 that are connected to each other. The sheet-like heat-conducting body 110 is connected to the oil lock 300. The disc-type threaded portion 210 is embedded in the sheet-like heat-conducting body 110. The drip-proof sealing tube 120 is located on a side of the sheet-like heat-conducting body 110 close to the oil lock 300. The outer wall of the drip-proof sealing tube 120 is connected to the oil lock 300, and the drip-proof sealing tube 120 is correspondingly arranged with the pin through hole 602, so that the conductive pin portion 220 passes through the atomizing base 600 to be connected to the battery. The conductive pin portion 220 is penetrated in the drip-proof sealing tube 120, and the drip-proof sealing tube 120 is used to isolate the conductive pin portion 220 from contact with the oil lock 300. In this embodiment, the sheet-like heat-conducting body 110 and the atomizing base 600 jointly clamp the oil lock 300, and the disc-type threaded portion 210 is embedded in the sheet-like heat-conducting body 110, so that the sheet-like heat-conducting body 110 is used to heat and atomize the tobacco oil on the oil lock 300. The anti-drip sealing tube 120 spans the oil lock 300, and part of the conductive pin portion 220 is accommodated in the anti-drip sealing tube 120, that is, the conductive pin portion 220 is penetrated in the anti-drip sealing tube 120, that is, the conductive pin portion 220 passes through the anti-drip sealing tube 120 and the pin through hole 602 in sequence, and protrudes and extends to connect with the power supply end of the battery. In this way, the disc-type threaded portion 210 is located in the sheet-like heat-conducting body 110, isolating the disc-type threaded portion 210 from the oil-locking member 300, and the conductive pin portion 220 is wrapped by the anti-drip sealing tube 120, so that the conductive pin portion 220 is isolated from the oil-locking member 300, reducing the probability of the disc-type heating element 200 contacting the smoke oil on the oil-locking member 300, thereby reducing the probability of the smoke oil on the oil-locking member 300 dripping onto the battery through the conductive pin portion 220, ensuring the surface cleanliness of the battery, thereby ensuring the safety of the electronic atomization device. In this embodiment, the oil injection through hole 104 is opened on the sheet-like heat-conducting body 110.

[0041] Furthermore, since the drip-proof sealing tube 120 is used to wrap the conductive pin portion 220, the outer wall of the drip-proof sealing tube 120 will contact the smoke oil on the oil locking member 300, so that the smoke oil will adhere to the outer wall of the drip-proof sealing tube 120. When the drip-proof sealing tube 120 is aligned with the pin through hole 602, it is still possible that the smoke oil on the outer wall of the drip-proof sealing tube 120 will leak out through the pin through hole 602.

[0042] To further improve the oil leakage resistance, please refer to Figure 4The diameter of the drip-proof sealing tube 120 is larger than the caliber of the pin through hole 602. The disc-type atomizing heating structure 10 also includes a leak-proof ring 700. The leak-proof ring 700 is located in the pin through hole 602. The leak-proof ring 700 is connected to the inner wall of the pin through hole 602, and the leak-proof ring 700 is sleeved on the conductive pin part 220. In this embodiment, the diameter of the drip-proof sealing tube 120 is larger than the caliber of the pin through hole 602, so that the end of the drip-proof sealing tube 120 away from the sheet-like heat-conducting body 110 is abutted against the atomizer base 600, that is, the end of the drip-proof sealing tube 120 away from the sheet-like heat-conducting body 110 is abutted against the side of the atomizer base 600 away from the battery, and the drip-proof sealing tube 120 is directly opposite to the pin through hole 602, so that the conductive pin part 220 passes through the pin through hole 602 to connect with the battery. At this time, the outer wall of the drip-proof sealing tube 120 and the atomizer base 600 block the smoke oil outside the pin through hole 602, effectively reducing the probability of the smoke oil penetrating into the pin through hole 602, thereby reducing the probability of the smoke oil dripping onto the battery. The leak-proof ring 700 is built into the pin through hole 602, and the inner ring center of the leak-proof ring 700 is on the same straight line as the hole center of the pin through hole 602. When the conductive pin part 220 passes through the pin through hole 602, the conductive pin part 220 is sleeved with the leak-proof ring 700, that is, the conductive pin part 220 abuts against the inner wall of the leak-proof ring 700. The tight fitting connection between the conductive pin part 220 and the leak-proof ring 700 further blocks the smoke oil, reduces the smoke oil that penetrates through the gap between the anti-drip sealing tube 120 and the atomizer base 600, and then drips onto the battery through the pin through hole 602, further improving the anti-leakage sealing performance of the disc-type atomization heating structure.

[0043] Furthermore, when the disc-type atomizing heating structure is placed flat or inverted, the smoke oil on the oil locking member 300 will gather toward the sheet-like heat-conducting body 110. Although the oil injection hole 104 is blocked by the oil injection seal 400 and the smoke oil cannot leak out through the oil injection hole 104, due to the manufacturing accuracy error between the sheet-like heat-conducting body 110 and the packaging sleeve, there will still be a certain contact gap between the sheet-like heat-conducting body 110 and the packaging sleeve, and the smoke oil is easy to leak out through this gap.

[0044] In order to further improve the oil leakage sealing performance of the disc type atomizing heating structure, please refer to Figure 5The disk-type atomizing heating structure 10 further includes a sealing snap ring 800. The sheet-like heat-conducting body 110 is provided with a sealing groove 112 connected to the oil injection through hole 104. A portion of the sealing snap ring 800 is clamped in the sealing groove 112. The sealing snap ring 800 abuts against the oil injection seal 400 so that the sealing snap ring 800 abuts against the inner wall of the packaging sleeve in an interference fit. In this embodiment, the oil injection through hole 104 is arranged close to the edge of the sheet-like heat-conducting body 110 so that the sealing groove 112 is connected to the oil injection through hole 104. For example, the side wall of the oil injection through hole 104 has a notch, and the notch is correspondingly connected to the sealing groove 112. The sealing snap ring 800 is arranged in the sealing groove 112, and the sealing groove 112 is arranged around the sheet-like heat-conducting body 110, so that the sealing snap ring 800 is located between the sheet-like heat-conducting body 110 and the inner wall of the packaging sleeve. Moreover, when the oil injection seal 400 seals the oil injection through hole 104, since the sealing groove 112 is connected to the oil injection through hole 104, part of the oil injection seal 400 is embedded in the oil injection through hole 104, so that the oil injection seal 400 squeezes the sealing snap ring 800. The ring 800 is located in the portion inside the oil injection hole 104, so that the oil injection seal 400 holds the sealing snap ring 800 against the inner wall of the packaging sleeve, thereby making the sealing snap ring 800 interference fit with the inner wall of the packaging sleeve to increase the squeezing force between the sealing snap ring 800 and the inner wall of the packaging sleeve, further reducing the gap between the sheet-like heat-conducting body 110 and the inner wall of the packaging sleeve caused by the sealing snap ring 800, thereby further improving the oil leakage-proof sealing performance of the disc-type atomizing heating structure.

[0045] This application also provides an electronic atomization device, see Figure 6, the electronic atomization device 20 includes a packaging sleeve 900 and a disc-type atomization heating structure 10 described in any of the above embodiments, the disc-type atomization heating structure 10 is inserted into the packaging sleeve 900, and the central air hole is connected to the air inlet channel of the packaging sleeve 900. In this embodiment, the disc-type atomization heating structure is used to be sleeved in the packaging sleeve, and includes: an atomization heat conductor and a disc-type heating element; the atomization heat conductor abuts against the inner wall of the packaging sleeve, and the atomization heat conductor is provided with a central air hole, and the central air hole is used to conduct airflow; part of the disc-type heating element has a planar threaded structure, and at least part of the planar threaded structure of the disc-type heating element is connected to the atomization heat conductor, and the disc-type heating element is used to be electrically connected to a battery to heat the atomization heat conductor. Since the area where the disk heating element is connected to the atomizing heat conductor is a planar threaded structure, that is, this part of the disk heating element is in the same plane and is threadedly distributed, after the disk heating element is energized, the threaded distribution structure ensures the uniformity of heating of the atomizing heat conductor, and the part of the disk heating element used to heat the atomizing heat conductor is located in the same plane, which reduces the material used for the disk heating element, thereby reducing the production cost of the electronic atomizing device.
