Description

Technical Field

[0001] The utility model relates to the technical field of consumer electronics, and more specifically to an atomization device for delaying flow rate and an electronic atomizer. Background Art

[0002] In order to prevent the leakage of the atomizing matrix, many existing electronic atomizers have liquid storage cotton installed in the oil storage bin to lock the liquid atomizing matrix. Although the liquid storage cotton can lock the atomizing matrix and reduce the risk of oil leakage, due to its own characteristics, a considerable part of the atomizing matrix remains in the liquid storage cotton, resulting in a waste of the atomizing matrix. When the existing oil storage bin is filled with liquid atomizing matrix, although the problem of the liquid storage cotton remaining in the atomizing matrix is ​​solved, the liquid atomizing matrix has a higher flow rate to the general atomizing core, which often causes the atomizing core to leak oil, giving the user a poor user experience.

[0032] Figures 1 to 6 The following is an accompanying drawing of the utility model; Figure 3 The dot-dashed line with a scissors in the middle is the flow path of the atomized matrix.

[0033] This embodiment provides an atomization device 100, see Figures 1 to 3, including an atomizer core 10, a first mounting member 20 arranged at one end of the atomizer core 10, and a second mounting member 30 arranged at the other end of the atomizer core 10. An oil-guiding cotton 40 is arranged at the oil inlet end of the atomizer core 10, and the atomized matrix first passes through the oil-guiding cotton 40 and then flows to the atomizer core 10. The oil inlet end of the atomizer core 10 is arranged on the outer surface between its two ends, and the atomized matrix flowing to the oil-guiding cotton 40 enters the atomizer core 10 through the oil inlet end of the atomizer core 10. Both ends of the oil-guiding cotton 40 stop at the first mounting member 20 and the second mounting member 30, and cover the oil inlet end of the atomizer core 10. Among them, the first mounting member 20, the second mounting member 30 and the two ends of the atomizer core 10 are all sealed and connected, so that the atomized matrix reaching the atomizer core 10 is prevented from flowing out from the connection between the atomizer core 10 and the first mounting member 20 and the second mounting member 30. The oil-conducting cotton 40 is arranged on the outside of the atomizer core 10, and forms a wrapping state for the outside of the atomizer core 10. In addition, the two ends of the oil-conducting cotton 40 extend to the first mounting member 20 and the second mounting member 30 respectively, and the oil-conducting cotton 40 contacts the ends of the first mounting member 20 and the second mounting member 30, which plays a role in limiting the oil-conducting cotton 40. The surface of the oil-conducting cotton 40 is connected to the oil storage bin where the atomizing matrix is ​​placed. The atomizing matrix flows in from the surface of the oil-conducting cotton 40, and penetrates through the oil-conducting cotton 40 and then flows to the atomizing core 10. The atomizing core 10 is powered on to generate heat, thereby heating the atomizing matrix and atomizing it. The oil-guiding cotton 40 is wrapped around the outside of the atomizer core 10, so that the atomizer matrix cannot flow directly onto the atomizer core 10, and the liquid atomizer matrix in the oil storage tank is prevented from quickly flowing into the atomizer core 10, which can effectively avoid the atomizer matrix from leaking oil at the atomizer core 10. At the same time, the oil-guiding cotton 40 has a guiding role and an oil storage role in the process of the atomizer matrix penetrating into the atomizer core 10.

[0034] The atomizer core 10 includes a mounting frame 11, a heating wire 12, and oil-permeable cotton 13. An atomization channel 14 is provided inside the oil-permeable cotton 13, and the heating wire 12 is provided inside the atomization channel 14. The oil-permeable cotton 13 is provided inside the mounting frame 11 and is located between the heating wire 12 and the mounting frame 11. The outer side of the mounting frame 11 is in contact with the oil-conducting cotton 40, so that the atomized matrix in the oil-conducting cotton 40 can flow to the heating wire 12.

[0035] Preferably, a fixing member 50 is provided on the outside of the oil-conducting cotton 40. One end of the fixing member 50 is connected to the first mounting member 20, and the other end is connected to the second mounting member 30. The fixing member 50 is a cylindrical structure, which can wrap the oil-conducting cotton 40 inside. One end of the fixing member 50 extends to the first mounting member 20, and one end of the fixing member 50 forms a sealing connection with the first mounting member 20; the other end of the fixing member 50 extends to the second mounting member 30, and similarly, one end of the fixing member 50 forms a sealing connection with the second mounting member 30. During installation, the first mounting member 20 and the second mounting member 30 are plugged toward the inside of the fixing member 50.

[0036] Preferably, the first mounting member 20 and the second mounting member 30 are made of silicone material, latex material, rubber material, gel, epoxy resin material, etc. After the first mounting member 20, the second mounting member 30, the mounting frame 11 and the fixing member 50 are connected, the sealing between the joints can be ensured.

[0037] Both ends of the atomizer core 10, the oil-guiding cotton 40 and the fixing member 50 are stopped at the first mounting member 20 and the second mounting member 30, so that the atomizer core 10, the oil-guiding cotton 40 and the fixing member 50 have a positioning function in the axial direction, and avoid mutual displacement between components during installation and use, thereby ensuring the reliability of the atomizer device 100. In addition, the first mounting member 20 and the second mounting member 30 form the atomizer core 10, the oil-guiding cotton 40 and the fixing member 50 into a whole, and the components are fixed to each other and modularly arranged, which effectively improves the installation efficiency and avoids failures during installation and use.

[0038] One end of the first mounting member 20 is plugged into one end of the fixing member 50, and a plurality of first sealing protrusions extending circumferentially are provided on the outer side of the first mounting member 20, so that the first mounting member 20 and the fixing member 50 can form a sealed connection after being plugged in and connected. Similarly, one end of the second mounting member 30 is plugged into one end of the fixing member 50, and a plurality of second protrusions extending circumferentially are provided on the outer side of the second mounting member 30, so that the second mounting member 30 and the fixing member 50 can form a sealed connection after being plugged in and connected. Both ends of the fixing member 50 are sealedly connected to the first mounting member 20 and the second mounting member 30, so that the atomized matrix in the oil-conducting cotton 40 cannot leak oil from the connection between the first mounting member 20, the second mounting member 30 and the fixing member 50.

[0039] See also Figure 3 , 4 , a mounting groove 21 for connecting the fixing member 50 is provided on the outside of the first mounting member 20. The above-mentioned first sealing protrusion is provided on the mounting groove 21, so that the fixing member 50 forms a sealed connection with the mounting groove 21 after being assembled. One end of the first mounting member 20 is inserted into the inside of the fixing member 50, and one end of the fixing member 50 is inserted into the mounting groove 21 on the outside of the first mounting member 20, so that the two can be fixedly connected. In addition, a limiting portion is provided at one end of the mounting groove 21 away from the fixing member 50, and after the fixing member 50 is connected to the first mounting member 20, one end of the fixing member 50 stops at the limiting portion.

[0040] See also Figure 3 , 5The outer side of the second mounting member 30 is also provided with a mounting position 31 for mounting the fixing member 50. The lower end of the fixing member 50 is plugged into the mounting position 31 of the second mounting member 30, so that one end of the fixing member 50 can be fixedly connected to the second mounting member 30. Specifically, the mounting position 31 is a step arranged on the outer periphery of the second mounting member 30, and one end of the fixing member 50 stops at the step surface. One end of the fixing member 50 is plugged into the mounting position 31 of the second mounting member 30, and the other end is connected to the mounting groove 21 of the first mounting member 20, and one end of the atomizer core 10 is connected to the first mounting member 20, and the other end is connected to the second mounting member 30, so the first mounting member 20, the second mounting member 30, the fixing member 50 and the atomizer core 10 can be tightly connected to form a whole, and can also be disassembled from each other.

[0041] For details, please refer to Figure 3 , 4 , a first sealing protrusion 201 is provided at the connection between the first mounting member 20 and the fixing member 50. The first sealing protrusion 201 is a protruding portion of the first mounting member 20, and the first sealing protrusion 201 is circumferentially arranged on the outer surface of the mounting groove 21 of the first mounting member 20, so that the connection between the first mounting member 20 and the fixing member 50 plays a sealing role, preventing the atomized matrix in the oil-guiding cotton 40 from flowing out from the connection between the first mounting member 20 and the fixing member 50. In other embodiments, the first sealing protrusion 201 can also be replaced by a sealing ring.

[0042] The first mounting member 20 is provided with an air outlet 22, and the air outlet 22 is connected to the atomization channel 14 of the atomization core 10. The heating wire 12 in the atomization channel 14 heats the atomization matrix and atomizes it, and then the atomization matrix can flow out from the air outlet 22. The air outlet 22 is provided in the middle of the first mounting member 20 and passes through both ends of the first mounting member 20.

[0043] The first mounting member 20 is provided with a first mounting hole 23 at one end facing the atomizer core 10. One end of the atomizer core 10 is connected to the first mounting hole 23. The first mounting hole 23 is connected to the air outlet 22. It can be understood that the first mounting hole 23 and the air outlet 22 are coaxially arranged, which increases the convenience of processing. The first mounting hole 23 is a stepped hole, and the end of the atomizer core 10 stops at the bottom of the first mounting hole 23. Preferably, a second sealing protrusion 202 is provided on the inner wall of the first mounting hole 23. After the atomizer core 10 is installed in the first mounting hole 23, the second sealing protrusion 202 contacts the outer side of the atomizer core 10 to form a sealing structure to prevent the atomization matrix of the oil-conducting cotton 40 from leaking.

[0044] See also Figure 3 , 5The connection surface between the mounting position 31 and the fixing member 50 is provided with a third sealing protrusion 301, so that the connection between the fixing member 50 and the mounting position 31 can play a sealing role. The third sealing protrusion 301 is circumferentially arranged on the outer surface of the mounting position 31, so that the connection surface between the fixing member 50 and the mounting position 31 forms a sealed connection, thereby preventing the atomized matrix of the oil-conducting cotton 40 from leaking from the connection. In other embodiments, the third sealing protrusion 301 can be replaced by a sealing ring.

[0045] The second mounting member 30 is provided with an air inlet 32. The air inlet 32 ​​is communicated with the atomization channel 14 of the atomization core 10. The air inlet 32 ​​runs through both ends of the second mounting member 30, and the end connected to the atomization core 10 is communicated with the atomization channel 14 of the atomization core 10. Air enters from the air inlet 32 ​​and passes through the atomization channel 14, thereby bringing the heated and atomized atomized matrix out from the air outlet 22.

[0046] The second mounting member 30 is provided with a second mounting hole 33 at one end facing the atomizer core 10. One end of the atomizer core 10 is connected to the second mounting hole 33, and the second mounting hole 33 is communicated with the air inlet 32. The second mounting hole 33 is a stepped hole, and one end of the atomizer core 10 abuts against the second mounting hole 33. It can be understood that the second mounting hole 33 and the air inlet 32 ​​are coaxially arranged, and after the atomizer core 10 is installed to the second mounting hole 33, the air inlet 32 ​​can be communicated with the atomization channel 14 of the atomizer core 10.

[0047] Preferably, a fourth sealing protrusion 302 is provided on the inner wall of the second mounting hole 33, so that the installation of the atomizer core 10 and the second mounting hole 33 is sealed. The fourth sealing protrusion 302 is circumferentially arranged in the second mounting hole 33. After one end of the atomizer core 10 stops at the bottom of the second mounting hole 33, the fourth sealing protrusion 302 is squeezed by the outer side of the atomizer core 10, thereby forming a sealed connection to prevent leakage of the atomized matrix of the oil-guiding cotton 40. In other embodiments, the fourth sealing protrusion 302 can be replaced by a sealing ring.

[0048] One end of the atomizer core 10 is plugged into the first mounting hole 23, and the other end is plugged into the second mounting hole 33, and both the first mounting hole 23 and the second mounting hole 33 are stepped holes. It is only necessary to insert one end of the atomizer core 10 into place, and then sleeve the oil-guiding cotton 40 from the unplugged end of the atomizer core 10 to the outside of the atomizer core 10, and then plug the fixing member 50 with the first mounting member 20 or the second mounting member 30, and finally install the first mounting member 20 or the second mounting member 30 from one end of the atomizer core 10. The whole installation process is convenient, and there is no need to calibrate the position of the oil-guiding cotton 40.

[0049] See also Figure 2 , 3, a plurality of oil holes 51 are arranged on the outside of the fixing member 50. The oil holes 51 are evenly distributed in the circumferential direction. Since both ends of the fixing member 50 are sealedly connected to the first mounting member 20 and the second mounting member 30, the atomized matrix can only flow to the oil-conducting cotton 40 through the oil holes 51, so that the oil-conducting cotton 40 has a slowing effect on the flow rate of the atomized matrix. Preferably, the oil holes 51 are rotationally symmetrically arranged on the outside of the fixing member 50, so that the oil-conducting cotton 40 can be evenly fed with oil.

[0050] Preferably, the oil hole 51 is arranged close to the bottom of the atomizer core 10. The oil hole 51 is connected to the oil storage tank, so that the atomized matrix in the oil storage tank can all flow from the oil hole 51 to the oil guide cotton 40, avoiding the waste of the atomized matrix.

[0051] The outer side of the atomizer core 10 is evenly distributed with oil inlet holes 15 in the circumferential direction, and the oil inlet holes 15 are the oil inlet end of the atomizer core 10. The oil inlet holes 15 are arranged away from the bottom of the atomizer core 10. Specifically, the oil inlet holes 15 are arranged on the mounting frame 11, and the atomized matrix of the oil-guiding cotton 40 can flow to the oil-infiltrating cotton 13 through the oil inlet holes 15, and then flow to the heating wire 12. The oil inlet holes 15 are arranged in a circumferentially evenly distributed pattern on the outer side of the mounting frame 11, which is conducive to the uniform entry of the atomized matrix into the oil-infiltrating cotton 13, and avoids the phenomenon of local dry burning caused by uneven inflow of the atomized matrix.

[0052] The existing atomizer core is generally directly connected to the oil storage tank. Especially when the atomizer matrix is ​​in liquid state, the atomizer matrix directly flows through the oil inlet hole 15 to the oil-seeping cotton 13, and then flows to the heating wire 12. The flow rate of the atomizer matrix is ​​too fast, which can easily cause the atomizer matrix to leak. In addition, during use, the atomizer matrix gathers too quickly on the oil-seeping cotton 13, which can easily lead to "oil explosion" phenomenon, or cause the atomizer matrix to be insufficiently heated, and there are a large number of liquid droplets in the smoke, affecting the taste.

[0053] See also Figure 2 , 3 , the oil inlet 15 is arranged away from the bottom of the atomizer core 10, that is, after installation, the oil inlet 15 is arranged close to the first mounting member 20, and the oil through hole 51 on the fixing member 50 is arranged close to the bottom of the atomizer core 10, that is, after installation, the oil through hole 51 is arranged close to the second mounting member 30. It can also be understood that the oil inlet 15 is close to the upper part of the oil-conducting cotton 40, and the oil through hole 51 is close to the lower part of the oil-conducting cotton 40, so the atomized matrix needs to flow from one end of the oil-conducting cotton 40 to the other end before it can flow to the oil-permeable cotton 13 through the oil inlet 15, which prolongs the flow path of the atomized matrix (such as Figure 3 The oil inlet hole 15 and the oil through hole 51 are staggered to increase the flow path of the atomized matrix and increase the curvature of the path, which can effectively reduce the flow rate of the atomized matrix and also reflects the oil guiding and oil storage functions of the oil guiding cotton 40.

[0054] After assembly, a spacing is provided between one end of the oil inlet hole 15 close to the bottom of the atomizer core 10 and one end of the oil through hole 51 close to the upper part of the atomizer core 10, which can be understood as the distance between the lower end of the oil inlet hole 15 and the upper end of the oil through hole 51. This spacing can prevent the atomized matrix from directly flowing through the oil through hole 51 and the oil inlet hole 15 to the oil-seeping cotton 13, thereby improving the effect of the oil-conducting cotton 40 in slowing down the flow rate of the atomized matrix, and the oil-conducting cotton 40 also serves the purpose of storing oil. Preferably, the spacing is at least 1 / 10 of the length of the oil-conducting cotton 40.

[0055] Preferably, the total area of ​​the oil holes 51 is 1%-15% of the surface area of ​​the oil-conducting cotton 40. More preferably, the total area of ​​the oil holes 51 is 3%-5% of the surface area of ​​the oil-conducting cotton 40. In the present application, the number of the oil holes 51 is four. In other embodiments, the number of the oil holes 51 is not limited and is rotationally symmetrically arranged on the outside of the fixing member 50. The total area of ​​the oil holes 51 is the sum of the areas of each individual oil hole 51. The total area of ​​the oil holes 51 and the surface area of ​​the oil-conducting cotton 40 are set according to a set ratio, which can balance the speed of the atomized matrix flowing to the oil-conducting cotton 40.

[0056] The thickness of the oil-conducting cotton 40 is at least 1 / 3 of the thickness or diameter of the atomizing device. The thickness of the oil-conducting cotton 40 determines the oil storage capacity and flow rate of the atomizing matrix. Too much thickness affects the oil storage capacity and flow rate, which will cause oil supply problems in the atomizing core 10, such as untimely oil supply, which will cause dry burning problems; if the thickness is small, the flow rate of the atomizing matrix is ​​too fast, which will cause oil leakage. The thickness of the oil-conducting cotton 40 in this embodiment is at least 1 / 3 of the thickness or diameter of the atomizing device, which can ensure the oil storage capacity of the oil-conducting cotton 40 and the flow rate of the atomizing matrix in the oil-conducting cotton 40.

[0057] Preferably, the material of the oil-conducting cotton 40 can be PP fiber cotton, non-woven fabric, etc. The oil-conducting cotton 40 can be a single piece of cotton or a multi-layer cotton.

[0058] Preferably, the weight of the oil-conducting cotton 40 is 0.1-0.2 g / cm3. The weight of the oil-conducting cotton 40 is an important parameter for measuring the flow rate of the atomizing matrix. If the weight is too small, the flow rate of the atomizing matrix will be too fast, which will cause the risk of oil leakage; if the weight is too large, it will hinder the flow of the atomizing matrix and cause the atomizing core 10 to dry out.

[0059] In other embodiments, because the oil-guiding cotton 40 is located at the oil inlet end of the atomizer core 10, that is, the oil-guiding cotton 40 is located at the oil inlet end of the oil inlet hole 15, the atomizer core 10 is provided with as many oil inlet holes 15 as possible, and the oil inlet ends of the oil inlet holes 15 are all provided with oil-guiding cotton 40, and the oil-guiding cotton 40 is designed in a distributed manner. The number of the oil-guiding cotton 40 matches the oil inlet holes 15, and an oil-guiding cotton 40 is separately provided at the oil inlet end of each oil inlet hole 15, which can save space, and the oil storage bin can accommodate more atomization substrates.

[0060] An electronic atomizer, see Figure 2 , 3 , 6, includes a housing 200, an oil cup assembly 300, a battery 400 and the above-mentioned atomizing device 100. Among them, the atomizing device 100 is arranged in the oil cup assembly 300. The oil cup assembly 300 is provided with a suction nozzle 310, and a mounting block 320 arranged at the lower end of the oil cup assembly 300. Preferably, the mounting block 320 is made of silicone, rubber, etc., so as to seal the oil cup assembly 300. An oil storage bin 330 is formed between the suction nozzle 310 and the mounting block 320 for holding liquid atomizing matrix. One end of the atomizing device 100 is connected to the suction nozzle 310, and the other end is connected to the mounting block 320. The oil through hole 51 of the atomizing device 100 is located in the oil storage bin 330. The liquid atomizing matrix in the oil storage tank 330 flows to the atomizing core 10 through the oil hole 51, the oil guiding cotton 40 and the oil inlet hole 15. During the flow of the atomizing matrix, the oil guiding cotton 40 serves to reduce the flow rate of the atomizing matrix.

[0061] Specifically, the suction nozzle 310 is provided with an extension portion 340 toward the oil storage bin 330, and the extension portion 340 is sealed and connected to the air outlet 22 of the first mounting member 20, so that the suction nozzle 310 is connected to the atomization channel 14 of the atomization core 10. The mounting block 320 is provided with a mounting groove 321 toward the oil storage bin 330, and the lower end of the atomization device 100 is installed in the mounting groove 321. And the mounting groove 321 is provided with an air inlet hole 322 connected to the air inlet hole 32 of the second mounting member 30, so that air can flow in from the air inlet hole 322. Among them, the atomization device 100 is installed with the oil cup assembly 300 as a whole, the first mounting member 20 is sealed and connected to the extension portion 340 of the suction nozzle 310, the second mounting member 30 is sealed and connected to the mounting groove 321, and the first mounting member 20 and the second mounting member 30 are also used as sealing materials, so the atomization device 100 can play a sealing role after installation, and there is no need to design other sealing connections, which improves the convenience and efficiency of installation.

[0062] The oil storage tank 330 contains liquid atomizing matrix, and the fluidity of the liquid atomizing matrix is ​​good, so the atomizing device 100 is provided with an oil-conducting cotton 40, so that the flow rate of the atomizing matrix is ​​reduced by the oil-conducting cotton 40 before entering the atomizing core 10, thereby reducing the liquid pressure on the atomizing core 10 and avoiding oil leakage caused by excessive flow rate; in addition, the oil-conducting cotton 40 directly supplies oil to the atomizing core 10 and also has the function of storing oil.

[0063] Compared with the prior art, the atomizer core 10 of the utility model is connected to the first mounting member 20 at one end and to the second mounting member 30 at the other end, and an oil-guiding cotton 40 is provided at the oil inlet end of the atomizer core 10. The oil-guiding cotton 40 has the function of reducing the flow rate of the atomizing matrix fluid atomizer core 10, and also has the function of guiding and storing oil, which can effectively reduce the risk of oil leakage. At the same time, the first mounting member 20 and the second mounting member 30 form the atomizer core 10, the oil-guiding cotton 40 and the fixing member 50 into a whole, and the modular design improves the installation efficiency.

[0064] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
