Description

Technical Field

[0001] The present application belongs to the technical field of electronic atomization, and in particular, relates to an atomization device and an atomization equipment. Background Art

[0002] The atomizer device is provided with an atomizer core and a liquid storage chamber. The liquid storage chamber stores the liquid matrix to be atomized. The atomizer core is used to atomize the liquid matrix stored in the liquid storage chamber into atomized gas that can be inhaled by the user. The atomizer core can be formed by a liquid guide piece made of a porous material and a heating element stacked together. When the atomizer core is working, the liquid guide piece is used to absorb the liquid matrix in the liquid storage chamber and continuously guide the liquid matrix to the heating element, so that the heating element heats the liquid matrix and evaporates it into atomized gas.

[0003] However, during the operation of the atomizer core, both the heating element and the liquid guide element will undergo thermal expansion and deformation due to the heat, and the porous material of the liquid guide element absorbs the liquid matrix, so its thermal expansion and deformation is greater than that of the heating element, so that the heating element will be lifted up by the liquid guide element, which may easily cause part of the heating element to be suspended relative to the liquid guide element after thermal expansion and deformation, thereby causing the heating element to dry burn. It can be seen that how to avoid the dry burning phenomenon that may occur when the heating element itself has a smaller degree of thermal expansion and deformation than the liquid guide element has become a technical problem that needs to be solved urgently.

[0047] First embodiment

[0048] See also Figure 1-7 The first embodiment of the present application provides an atomizing device 1, which includes a housing 10, a bracket 20, a base 30 and an atomizing core 40. An air inlet 11 and a mist outlet pipe 12 connected to the air inlet 11 and extending into the housing 10 are provided at one end of the housing 10. The atomized gas generated inside the atomizing device 1 reaches the air inlet 11 through the mist outlet pipe 12, and then the user can inhale the atomized gas through the air inlet 11; an opening is provided at the other end of the housing 10, and the base 30 is plugged and installed in the opening of the housing 10 to block the housing 10. The bracket 20 is installed in the housing 10 and sleeved on the end of the mist outlet pipe 12 away from the air inlet 11. The bracket 20, the housing 10 and the mist outlet pipe 12 enclose a liquid storage chamber 13, and the liquid storage chamber 13 is used to store the liquid matrix to be atomized. The atomizer core 40 includes a heating element 41 and a liquid guide element 42 stacked up and down. The liquid guide element 41 is a porous material that can undergo thermal expansion and deformation. The heating element 41 and the liquid guide element 42 are pressed tightly between the bracket 20 and the base 30, and the heating element 41 and the liquid guide element 42 are closely attached to each other. The bracket 20 is also provided with a liquid guide channel 21, which is used to guide the liquid matrix in the liquid storage chamber 13 to the liquid guide element 42. The liquid guide element 42 is used to absorb the liquid matrix and guide the liquid matrix to the heating element 41, so that the heating element 41 can heat the liquid matrix to evaporate the liquid matrix into atomized gas.

[0049] It should be noted that the “heating element 41 and the liquid guiding element 42 are pressed tightly between the bracket 20 and the base 30” means that the bracket 20 and the base 30 at least directly press the stacked portion of the heating element 41 and the liquid guiding element 42. The “heating element 41 and the liquid guiding element 42 are closely attached to each other” means that at least a portion of the heating element 41 and the liquid guiding element 42 are closely attached to each other after being pressed by the bracket 20 and the base 30, and there is no situation where the liquid guiding element 41 and the heating element 42 are completely out of contact.

[0050] It can be understood that because the liquid guide member 42 is a porous material that can undergo thermal expansion and deformation, the liquid guide member 42 is easily heated by the heating element 41 and deformed by thermal expansion when the atomizer core 40 is working. The porosity of the deformed liquid guide member 42 increases, thereby increasing its liquid guide rate, which may cause leakage of the atomizer 1. In the embodiment of the present application, the heating element 41 and the liquid guide member 42 are stacked and compressed between the bracket 20 and the base 30, so that the portion of the liquid guide member 42 directly compressed by the bracket 20 and the base 30 will not undergo thermal expansion and deformation after being heated by the heating element 41, and only the portion of the liquid guide member 42 that is not directly compressed by the bracket 20 and the base 30 may undergo thermal expansion and deformation due to heating. In this way, the porosity increase of the entire liquid guide member 42 due to thermal expansion and deformation is relatively small, so that the liquid guide rate is not too high, and the leakage phenomenon that may be caused by the excessively high liquid guide rate of the liquid guide member 42 is avoided. At the same time, since the heating element 41 and the liquid guide element 42 are pressed between the bracket 20 and the base 30, the heating element 41 can be prevented from being deformed to a certain extent, so that the heating element 41 can maintain a relatively stable working state, avoiding dry burning or core sticking caused by deformation of the heating element 41. In addition, the bracket 20 serves as a component for pressing the atomization core 40 and a component for setting the liquid guide channel 21. Compared with the atomization device in which the two components are set separately, the number of parts is reduced, thereby reducing the assembly and processing costs. In addition, by selecting a suitable liquid guide rate of the liquid guide element 42 and then installing the liquid guide element 42 between the bracket 20 and the base 30, it is also possible to avoid the liquid guide rate of the liquid guide element 42 being too low, thereby avoiding the dry burning or core sticking caused by the heating element 41.

[0051] Specifically, in the first embodiment, the liquid matrix is ​​selected from electronic cigarette liquid, so that the atomization device 1 can correspond to the atomization component of the electronic cigarette; the liquid guide member 42 is selected from absorbent cotton, so that the liquid guide member 42 has good performance of absorbing and guiding the liquid matrix.

[0052] Specifically, in the first embodiment, the liquid guiding member 42 is configured to be in a rectangular block shape, and the heating member 41 is configured to be in a rectangular sheet shape, so that the heating member 41 and the heat conducting member 42 can maintain a closer fit after being stacked.

[0053] See also Figure 2-6 In the first embodiment, a mounting groove 31 is provided on one end of the base 30 that is inserted into the interior of the housing 10, and the liquid guiding member 42 is installed in the mounting groove 31. The heating member 41 includes a heating portion 411 and a mounting portion 412. The heating portion 411 is closely arranged above the liquid guiding member 42, and the mounting portion 412 is fixed to the portion of the base 30 located around the mounting groove 31.

[0054] It can be understood that the liquid guide 42 is made of porous material, and its thermal expansion deformation after absorbing the liquid matrix is ​​usually greater than the thermal expansion deformation of the heating element 41. In the case where the heating element 41 and the liquid guide 42 are not fixed and limited, the heating element 41 is easily pushed up by the liquid guide 42 due to the thermal expansion deformation caused by the liquid guide 42 being heated, thereby causing part of the heating element 41 to be suspended, thereby causing the heating element 41 to dry burn or burn. In this embodiment, the heating element 41 is limited by the base 30 because its mounting portion 412 is fixed on the base 30, thereby avoiding the possibility that the heating element 41 is pushed up due to the thermal expansion deformation of the part of the liquid guide 42 that is not pressed, thereby causing part of the heating element 41 to be suspended and dry burn. In other words, in this embodiment, even if the unpressed portion of the liquid guiding member 42 undergoes thermal expansion and deformation, the heating element 41 cannot break away from the contact with the liquid guiding member 42 due to the limitation of the base 30. The heating element 41 may only be propped up by the liquid guiding member 42 during expansion and deformation and always maintain a close fit with the liquid guiding member 42, and the heating element 41 will not be suspended in the air.

[0055] On the other hand, because the heating portion 411 of the heating element 41 is closely arranged above the liquid guiding element 42, the atomized gas generated by the heating element 41 heating and evaporating the liquid matrix can be directly carried by the airflow above the atomization core 40 to the mist outlet pipe 12 when it encounters the airflow that enters the atomization device 1 from the outside and reaches the top of the atomization core 40 due to the user's inhalation, and then directly reaches the air inlet 11 through the mist outlet pipe 12 for the user to inhale. This reduces the structural parts that the atomized gas may pass through in the atomization device 1 after it is generated, reduces the impact of the atomized gas, makes the delivery path of the atomized gas shorter and has no tortuous path, thereby reducing the condensate that may be generated by the atomized gas in the atomization device 1, improves the delivery rate of the atomized gas, and ensures that the atomized gas reaching the air inlet 11 can better retain the original components in the liquid matrix and the particles are full, so that the user's inhalation taste is better.

[0056] See also Figure 2-6 In the first embodiment, a positioning column 32 is provided on one end of the base 30 that is plugged into the inside of the housing 10. The positioning column 32 is arranged around the mounting groove 31. A limiting hole 413 is provided on the mounting portion 412. The positioning column 32 is interference-connected with the limiting hole 413, so that the heating element 41 is fixed on the positioning column 32. It can be understood that by fixing the heating element 41 on the positioning column 32 of the base 30, the heating element 41 can be limited by the base 30, so that in the process of the liquid guide member 42 undergoing thermal expansion and deformation to push the heating element 41 upward, the heating element 41 is always limited above the liquid guide member 42, ensuring that the heating element 41 always maintains a close fit with the liquid guide member 42, avoiding the situation that the heating element 41 may be lifted up by the liquid guide member 42 and part of it is suspended in the air, thereby causing dry burning.

[0057] See also Figure 2-7 In the first embodiment, the heating element 41 includes a heating portion 411 and mounting portions 412 disposed on both sides of the heating portion 411 along the length direction of the heating portion 411, each mounting portion 412 is provided with two limiting holes 413, and the base 30 is provided with two positioning posts 32 corresponding to the two limiting holes 413 on each mounting portion 412, and the two limiting holes 413 disposed on each mounting portion 412 are symmetrically disposed about the central axis in the length direction of the heating portion 411. By providing the above-mentioned four limiting holes 413 and the four positioning posts 32 in interference connection, it can be ensured that the heating element 41 is uniformly fixed and limited to the base 30 without being separated from the base 30.

[0058] See also Figure 2-6 In the first embodiment, the atomizer 1 is provided with an air intake channel 61 connected to the external space, and the base 30 is configured with an air intake space 33 below the atomizer core 40, and a first air flow window 34 and a second air flow window 35 penetrating the side wall are provided on the side wall of the base 30, and an air flow gap 14 is provided between the side wall of the base 30 and the inner wall of the shell 10, and the air intake channel 61 is connected to the air flow gap 14 through the air intake space 33 and the first air flow window 34 in sequence, and the bracket 20 is configured with an air flow cavity 24 above the atomizer core 40, and the air flow gap 14 is connected to the air flow cavity 24 through the second air flow window 35, and the air flow cavity 24 is connected to the mist outlet pipe 12.

[0059] It can be understood that by constructing the air intake channel 61 and the first air flow window 34, the second air flow window 35, and constructing the air intake space 33 below the atomizer core 40, an air flow gap 14 is set between the side wall of the base 30 and the inner wall of the shell 10, and an air flow cavity 24 is set above the atomizer core 40, the outside air can reach the air flow cavity 24 through the air intake space 33, the first air flow window 34, the air flow gap 14 and the second air flow window 35 after entering the air intake channel 61. In this way, the outside air can reach the top of the atomizer core 40 from the bottom of the atomizer core 40 through the side air flow gap 14 without interfering with the structural design of the atomizer core, and then the atomized gas is carried above the atomizer core 40 and then sent to the mist outlet pipe 12 for the user to inhale. This not only ensures that the airflow channel is smooth when the user inhales, but also fully considers and reasonably utilizes the structure and installation position of the base 30, the bracket 20, the shell 10 and the atomizer core 40, avoiding the problem of the atomizer device 1 having an overly complex structure and high processing cost that may exist in other ways of setting the airflow channel, such as setting an airflow duct separately.

[0060] See also Figure 2-6In the first embodiment, a first turning surface 25 and a second turning surface 26 are provided on the inner wall of the airflow cavity 24, the second airflow window 35 is connected to the first turning surface 25, the first turning surface 25 is connected to the second turning surface 26, and the second turning surface 26 is connected to the inner wall of the mist outlet pipe 12.

[0061] It can be understood that, because the above-mentioned first turning surface 25 and the second turning surface 26 are provided, the gas in the airflow gap 14 will be blocked by the first turning surface 25 and the second turning surface 26 after entering the airflow cavity 24 through the second airflow window 35, and can stay in the airflow cavity 24 for a short time, so that the atomized gas generated by the liquid matrix can be entrained and carried to the mist outlet pipe 12, and the gas is prevented from directly passing over the atomizer core 40 and entering the mist outlet pipe 12 without carrying the atomized gas after entering the airflow cavity 24.

[0062] Specifically, in the first embodiment, the first turning surface 25 and the second turning surface 26 are both L-shaped turning surfaces, and the first turning surface 25 and the second turning surface 26 are both arranged on the portion of the bracket 20 that surrounds the inner wall of the above-mentioned airflow cavity 24, and the mist outlet pipe 12 is arranged directly above the heating part 411 of the heating element 41. Such a configuration can ensure that the gas entering the airflow chamber 24 through the second airflow window 35 must bypass the first turning surface 25 in an L-shaped movement path, thereby ensuring that this part of the gas can carry the atomized gas; and because the mist outlet pipe 12 is located directly above the heating part 411, it can also ensure that the mixed gas after carrying the atomized gas can enter the mist outlet pipe 12 in a straight path without being blocked by the second turning surface 26, so that the second turning surface 26 can only be used to block the gas entering the airflow chamber 24 through the second airflow window 35 and will not block the mixed gas that needs to be inhaled by the user after carrying the atomized gas; and the first turning surface 25 and the second turning surface 26 are directly arranged on the bracket 20, which fully utilizes and takes into account the structure and assembly position of the bracket 20 without increasing the manufacturing and processing costs.

[0063] More specifically, the bracket 20 is provided with an annular strip 27 directly above the heating portion 411 of the heating element 41, and the mist outlet pipe 12 is installed on the upper end surface of the annular strip 27 and is connected to the annular strip 27, so that the gas in the space above the atomization core 40 can enter the mist outlet pipe 12 through the annular strip 27, and the side wall surface and the lower end surface of the annular strip 27 constitute the above-mentioned second turning surface 26.

[0064] See also Figure 2-5In the first embodiment, the bracket 20 is provided with a clamping protrusion 22 at one end of the liquid guiding channel 21 close to the atomizer core 40, and the clamping protrusion 22 is arranged around the liquid guiding channel 21. The mounting portion 412 of the heating element 41 is provided with an avoidance notch 414 corresponding to the clamping protrusion 22. The clamping protrusion 22 passes through the avoidance notch 414 and is pressed on the liquid guiding element 42, thereby ensuring that the liquid guiding element 42 can be pressed between the bracket 20 and the base 30, preventing the liquid guiding element 42 from thermal expansion deformation after being heated, which may cause the problem of excessive liquid guiding rate and upward lifting of the heating element 41.

[0065] A pressing strip 23 is also provided on the bracket 20. The length direction of the pressing strip 23 is the same as the thickness direction of the atomizer core 40. One end of the pressing strip 23 close to the atomizer core 40 is pressed against the heating portion 411 of the heating element 41. By providing a special pressing strip 23 to press the heating portion 411 of the heating element 41, it is possible to prevent the heating portion 411 of the heating element 41 from thermal expansion deformation, so that the heating element 41 works stably. Moreover, because the heating element 41 and the liquid guide member 42 are stacked, the pressing strip 23 also presses the heating element 41 and the liquid guide member 42 between the bracket 20 and the base 30, ensuring that the heating portion 411 of the heating element 41 always keeps a close fit with the liquid guide member 42.

[0066] See also Figure 2-4 In the first embodiment, the atomizing device 1 further includes a connector 60 and a liquid-absorbing cotton 50. The base 30 is provided with a first mounting position 36 and a second mounting position 37 in sequence below the atomizing core 40 and in a direction away from the atomizing core 40. The liquid-absorbing cotton 50 is installed at the first mounting position 36, and the connector 60 is installed at the second mounting position 37. The connector 60 is arranged to penetrate the liquid-absorbing cotton 50. A through channel is also formed on the connector 60, and the through channel is the above-mentioned air inlet channel 61. One end of the connector 60 facing the atomizing core 40 penetrates the liquid-absorbing cotton 50 and extends above the liquid-absorbing cotton 50. The part of the connector 60 extending above the liquid-absorbing cotton 50, the liquid-absorbing cotton 50, and the base 30 form a buffer chamber 51.

[0067] It can be understood that by providing the absorbent cotton 50, the condensate that may be generated in the atomizing device 1 can be absorbed to prevent the condensate from leaking outward; by providing a through channel as an air inlet channel 61 on the connector 60, the outside air can enter the interior of the atomizing device 1 through the air inlet channel 61; by providing the above-mentioned buffer chamber 51, excess condensate that exceeds the adsorption capacity of the absorbent cotton 50 can be stored to further prevent the leakage of the condensate.

[0068] Specifically, in the first embodiment, the air intake space 33 is located above the liquid absorbent cotton 50 and the connector 60 , and the air intake space 33 is the space above the liquid absorbent cotton 50 and the connector 60 and enclosed by the base 30 .

[0069] See also Figure 2-4In the first embodiment, the atomizing device 1 further includes a first electrode 70 and a second electrode 80. The base 30 is provided with a first plug hole 38 and a second plug hole 39. The first electrode 70 and the second electrode 80 are respectively plugged and installed in the first plug hole 38 and the second plug hole 39, and the first electrode 70 and the second electrode 80 extend out of the first plug hole 38 and the second plug hole 39 respectively to form an electrical connection with the heating element 41. By providing the first electrode 70 and the second electrode 80 to form an electrical connection with the heating element 41, the heating element 41 can be electrically connected to an external power supply device through the first electrode 70 and the second electrode 80, so that the heating element 41 can generate heat after being powered on to heat the liquid matrix to generate atomized gas.

[0070] The atomizer device 1 provided in the first embodiment of the present application comprises an atomizer core 40 including a stacked heating element 41 and a liquid guide element 42, the liquid guide element 42 being installed in a mounting groove 31 provided on the base 30, the heating element 41 comprising a heating portion 411 and a mounting portion 412, the heating portion 411 being closely arranged above the liquid guide element 412, and the mounting portion 412 being fixed to a portion of the base 30 located around the mounting groove 31, so that when the atomizer core 40 is working, even if both the heating element 41 and the liquid guide element 42 are heated to generate thermal expansion deformation and the liquid guide element 42 is deformed The degree of thermal expansion of the liquid guiding member 42 is greater than that of the heating element 41. When the liquid guiding member 42 undergoes thermal expansion and deformation and applies an upward force to the heating element 41, the heating element 41 is also limited by the base 30 because the mounting portion 412 is fixed to the base 30. As a result, the heating portion 411 is always tightly covered on the liquid guiding member 42 before and after the liquid guiding member 42 undergoes thermal expansion and deformation, thereby preventing the heating element 41 from being lifted up and suspended in the air due to a greater degree of deformation of the liquid guiding member 42, and solving the problem that the heating element 41 may burn dry.

[0071] The first embodiment of the present application also provides an atomization device, which includes the atomization device 1 and a power supply device electrically connected to the atomization device 1. By electrically connecting the power supply device to the atomization device 1, the power supply device can provide electrical energy to the atomization device 1, so that the atomization core 40 inside the atomization device 1 can work normally after being powered on, so that the heating element 41 heats the liquid matrix to generate atomized gas.

[0072] The atomization device provided in the first embodiment of the present application includes the above-mentioned atomization device 1, so that the heating part 411 can always be tightly covered on the liquid guiding part 42 before and after the liquid guiding part 42 undergoes thermal expansion and deformation, thereby avoiding the situation where the heating part 41 may be lifted up and suspended in the air due to a greater degree of deformation of the liquid guiding part 42, thereby solving the problem that the heating part 41 may dry burn.

[0073] Second embodiment

[0074] See also Figure 8-10 The second embodiment of the present application provides an atomization device 1, which is different from the first embodiment in that:

[0075] In the second embodiment, the first electrode 70 and the second electrode 80 extend out of the first plug hole 38 and the second plug hole 39 respectively and are fixedly connected to the mounting portion 412 .

[0076] Specifically, in the second embodiment, the first electrode 70 and the second electrode 80 are respectively fixed in the first plug hole 38 and the second plug hole 39, and the first electrode 70 and the second electrode 80 both penetrate the mounting portion 412 of the heating element 41 and form a fixed connection with the mounting portion 412 of the heating element 41.

[0077] It can be understood that because the heating element 41 is directly fixedly connected to the first electrode 70 and the second electrode 80 without welding leads to connect the first electrode 70 and the second electrode 80, the lead cost and welding cost are saved. In addition, because the heating element 41 is fixedly connected to the first electrode 70 and the second electrode 80, the heating element 41 can also be limited by the first electrode 70 and the second electrode 80, thereby preventing the heating element 41 from being partially suspended in the air and causing dry burning due to the upward push of the liquid guide 42 after the liquid guide 42 expands and deforms. In other words, in the second embodiment, the first electrode 70 and the second electrode 80 simultaneously play the dual role of electrically connecting the heating element 41 and fixing the heating element 41.

[0078] More specifically, in the second embodiment, the first electrode 70 and the second electrode 80 are respectively provided with a first annular groove (not shown in the figure) and a second annular groove (not shown in the figure) at one end of the mounting portion 412 passing through the heat generating element 41, and the first solder portion 71 and the second solder portion 81 are respectively provided at the first annular groove and the second annular groove, and the first electrode 70 and the second electrode 80 are respectively fixedly connected to the mounting portion 412 of the heat generating element 41 through the first solder portion 71 and the second solder portion 81.

[0079] It should be noted that the first solder portion 71 and the second solder portion 81 are solder joints formed by a spot soldering process. During the spot soldering process, the first solder portion 71 and the second solder portion 81 are formed in the first annular groove and the second annular groove, respectively, and extend outward after filling the first annular groove and the second annular groove, until the first solder portion 71 and the second solder portion 81 contact and form a fixed connection with the mounting portion 412 of the heating element 41, thereby achieving the first electrode 70 and the second electrode 80 being fixedly connected to the mounting portion 412 of the heating element 41 through the first solder portion 71 and the second solder portion 81, respectively.

[0080] It can be understood that the heating element of the atomizer core 40 is generally thin. If the first electrode 70 and the second electrode 80 directly pass through the heating element 41 and completely form an interference connection with the heating element 41, it is easy to cause damage to the heating element 41; and if the first electrode 70 and the second electrode 80 do not form a complete interference connection with the heating element 41, the first electrode 70 and the second electrode 80 cannot form a good surface contact with the heating element 41, which will affect the power supply of the heating element 41 and the stability of the fixed connection of the heating element 41; therefore, in the second embodiment, the first solder portion 71 and the second solder portion 81 are selected to realize the connection between the heating element 41 and the first electrode 70 and the second electrode 80. In the process of spot soldering, if spot soldering is directly performed on one end of the first electrode 70 and the second electrode 80 passing through the heating element 41, a cold solder joint is likely to occur, which will also affect the connection between the heating element 41 and the first electrode 70 and the second electrode 80, causing the heating element 41 to be separated from the first electrode 70 and the second electrode 80. In the second embodiment, by arranging the first annular groove and the second annular groove at one end of the first electrode 70 and the second electrode 80 passing through the heat generating element 41, and then arranging the first solder portion 71 and the second solder portion 81 at the first annular groove and the second annular groove respectively, the first electrode 70 and the second electrode 80 can be fixedly connected to the mounting portion of the heat generating element 41 through the first solder portion 71 and the second solder portion 81 respectively and form an electrical connection with the heat generating element 41, while avoiding the above-mentioned possible problems.

[0081] In the second embodiment, the housing 10 is provided with an air inlet window 15 penetrating through its side wall, the air inlet window 15 is communicated with the space above the atomizer core 40 , and the space above the atomizer core 40 is communicated with the mist outlet pipe 12 .

[0082] It can be understood that by directly arranging an air inlet window 15 on the side wall of the shell 10 and connecting the air inlet window 15 with the space above the atomizer core 40, the outside air can directly pass through the side wall of the shell 10 to reach the top of the atomizer core 40, and then enter the mist outlet pipe 12 after carrying the atomized gas for the user to inhale. Compared with the air inlet channel 61 arranged below the atomizer core 40, the entire air flow channel of the atomizer device 1 in this embodiment is shorter and does not have any tortuous bends, reducing the air flow loss caused by the bending of the air flow, so that the atomized gas reaching the air inlet 11 can retain more original components of the liquid matrix and the particles are fuller, which can achieve a better inhalation experience.

[0083] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
