Atomizers and electronic atomization devices

Abstract

This application discloses an atomizer and an electronic atomizing device. The atomizer includes: a housing defining a liquid storage chamber; a seal for sealing the liquid storage chamber; a tubular body; a support for positioning the seal; and an atomizing assembly held within the tubular body. The seal has a through-hole through which the tubular body passes. The tubular body has a first opening and a second opening communicating with the atomizing assembly. The seal also includes a first fluid channel and a second fluid channel communicating with the through-hole. The tubular body is configured to move relative to the seal between a first position and a second position. When the tubular body moves relative to the seal to the first position, the first opening communicates with the first fluid channel, and the second opening communicates with the second fluid channel. When the tubular body moves relative to the seal to the second position, the first opening and the first fluid channel are misaligned, and the second opening and the second fluid channel are misaligned. This configuration effectively reduces the probability of leakage when the atomizer is idle.

Description

Technical Field

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

[0002] Traditional tobacco products (e.g., cigarettes, cigars, etc.) produce tobacco smoke through combustion during use. Existing technologies offer alternatives to these traditional tobacco products by releasing compounds through heating without combustion. Examples of such products are electronic atomizing devices, which typically include a reservoir for storing a liquid matrix and a heating element. The liquid matrix in the reservoir flows to the heating element for heating and atomization, producing inhalable vapor or aerosol. This liquid matrix may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin).

[0003] Electronic atomizing devices are usually equipped with a movable part with a liquid inlet. When the user uses it for the first time, the user needs to push the movable part from the first position to the second position to expose the liquid inlet and connect it with the liquid storage chamber. The liquid matrix in the liquid storage chamber can then flow to the heating element through the liquid inlet for atomization.

[0004] However, once the moving part is pushed from the first position to the second position in the above manner, it cannot return to the first position from the second position. At this time, the liquid inlet will remain connected to the liquid storage chamber, which can easily lead to leakage. Utility Model Content

[0005] This application provides an atomizer and an electronic atomizing device to solve the technical problem that after the existing electronic atomizing device is used up, the liquid matrix in the storage chamber remains in communication with the atomizing component, which leads to easy leakage of the atomizer.

[0006] At least one embodiment of this application provides an atomizer, including: The shell defines a reservoir for storing a liquid matrix; A sealing element for sealing the liquid storage cavity; A tubular body is disposed in the liquid storage cavity; A support member is fixedly disposed within the housing to provide support for the seal and restrict the movement of the seal relative to the housing; An atomizing component is held within the tubular body, the atomizing component being used to atomize the liquid matrix to generate an aerosol; The sealing element is provided with a through hole for the tubular body to pass through. The tube wall of the tubular body is provided with a first opening and a second opening that communicate with the atomizing component. The sealing element also includes a first fluid channel and a second fluid channel that communicate with the through hole. The first fluid channel is used to provide a flow path for the liquid matrix, and the second fluid channel is used to provide a flow path for external air. The tubular body is configured to rotate or move linearly relative to the seal between a first position and a second position. When the tubular body is in the first position, the first opening communicates with the first fluid channel, and the second opening communicates with the second fluid channel. When the tubular body is in the second position, the first opening is offset from the first fluid channel and sealed by the seal, and the second opening is offset from the second fluid channel and sealed by the seal.

[0007] In one embodiment, the atomizer includes an operating part that is at least partially exposed outside the housing, and the tubular body is fixedly connected to the operating part, thereby allowing the operating part to drive the tubular body to rotate or move linearly.

[0008] In one embodiment, the housing includes a main housing defining the liquid reservoir and a bottom cover connected to the main housing, the bottom cover being used to hold the tubular body and being rotatable relative to the housing or the support.

[0009] In one embodiment, the bottom cover has an air inlet, and an airflow chamber is provided between the bottom cover and the support member, the airflow chamber being in communication with the air inlet and the second fluid channel.

[0010] In one embodiment, the housing includes a main housing defining the liquid storage cavity, one of the main housing and the bottom cover being provided with a groove extending in the rotation direction, and the other being provided with a latching part, the latching part being slidably engaged in the groove; The slot has a first inner wall and a second inner wall that are arranged opposite to each other along the rotation direction. The first inner wall is used to define the first position, and the second inner wall is used to define the second position.

[0011] In one embodiment, the bottom cover is provided with an electrical connection portion for electrical connection with a power supply mechanism, the electrical connection portion being configured as an annular shape and having the same axis of rotation as the bottom cover.

[0012] In one embodiment, the seal includes an end face for sealing the reservoir and an extension extending away from the end face, wherein a first fluid channel is disposed on the side of the extension near the end face and a second fluid channel is disposed on the side of the extension away from the end face.

[0013] In one embodiment, the extension has a first end face facing the liquid storage cavity and a second end face disposed opposite to the first end face, the first end face being provided with a first groove for defining the first fluid channel, and the second end face being provided with a second groove for defining the second fluid channel.

[0014] In one embodiment, the support further includes a plug groove adapted to the extension, the extension being inserted into the plug groove.

[0015] At least one embodiment of this application also provides an electronic atomizing device, including the atomizer described in the above embodiments, and a power supply mechanism for connecting to the atomizer and providing electrical power to the atomizer.

[0016] The atomizer provided in the above embodiments, by providing a first fluid channel on the seal and a first opening communicating with the atomizing component on the wall of the tubular body, allows the tubular body to move between a first position and a second position relative to the seal. When the user needs to use the atomizer, the user can operate the tubular body relative to the seal from the second position to the first position to open the first fluid channel, allowing the liquid matrix to flow to the atomizing component through this channel. After use, the user can operate the tubular body relative to the seal to return from the first position to the second position to close the first fluid channel, preventing the liquid matrix from flowing to the atomizing component. This avoids the liquid matrix from remaining connected to the atomizing component when the atomizer is idle, reducing the probability of leakage. Furthermore, since the seal is supported on a support, the support can position the seal, preventing displacement or deformation of the seal during the rotation of the tubular body.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] One embodiment of this application provides an atomizer 100 for atomizing a liquid matrix to generate an aerosol that can be inhaled by a user, such as... Figure 1 and Figure 2 As shown, the atomizer 100 includes a housing 10, which includes a main housing 11 and a bottom cover 12 connected to the main housing 11. The main housing 11 has a first end 111 and a second end 112 opposite to each other along its length. The first end 111 forms a mouthpiece 1111, which has an outlet 11111 for aerosol to escape from the atomizer 100. The user can inhale the aerosol by inhaling through the mouthpiece 1111. The second end 112 is open, and at least a portion of the bottom cover 12 extends into the main housing 11 through the opening of the second end 112 to provide support for at least some of the components in the main housing 11.

[0025] The main housing 11 is provided with a liquid storage chamber 113 for storing atomizable liquid matrix. The atomizer 100 also includes a tubular body 20 extending longitudinally in the liquid storage chamber 113. The tubular body 20 holds an atomizing component 30 for atomizing the liquid matrix to generate an aerosol. The atomizing component 30 includes a liquid guide 31 and a heating element 32 attached to the liquid guide 31. The tube wall of the tubular body 20 is provided with a first opening 21 that communicates with the atomizing component 30. The first opening 21 is used for the liquid matrix in the liquid storage chamber 113 to flow into the tubular body 20 and then into the liquid guide 31. The liquid guide 31 can then further transfer the liquid matrix to the heating element 32. The heating element 32 heats and atomizes the liquid matrix to generate an aerosol and releases the generated aerosol into the tubular body 20.

[0026] The liquid guiding element 31 is made of a porous material, which can be any of the following: cotton fiber, non-woven fabric, fiberglass rope, porous ceramic, or porous glass. This allows the liquid guiding element 31 to absorb the liquid matrix and transfer it through its internal pores or microporous structure. Correspondingly, the heating element 32 can be attached to the liquid guiding element 31 or wound around it by means of printing, deposition, sintering, or physical assembly.

[0027] In some embodiments, the atomizing component 30 may also employ ultrasonic atomization. The atomizing component 30 includes an ultrasonic atomizing plate, which atomizes the liquid matrix through high-frequency vibration of the ultrasonic atomizing plate to generate an aerosol. This application does not limit the form of the atomizing component 30, as long as the atomizing component 30 can atomize the liquid matrix in the liquid storage chamber 113 to generate an aerosol.

[0028] In some embodiments, such as Figure 2 As shown, the air outlet of the tubular body 20 is connected to the air outlet 11111 of the suction nozzle 1111, so that the aerosol released in the tubular body 20 can be further output from the tubular body 20 to the suction nozzle 1111 for the user to inhale.

[0029] Furthermore, in some embodiments, the atomizer 100 may not have a mouthpiece 1111. The atomizer 100 only needs to have an air outlet for the aerosol to escape. Instead, a mouthpiece is provided on the power supply mechanism that works with the atomizer 100. When the atomizer 100 is installed on the power supply mechanism, the air outlet of the atomizer 100 is aligned and connected with the mouthpiece of the power supply mechanism. The user can inhale the aerosol by sucking through the mouthpiece on the power supply mechanism.

[0030] Please continue reading. Figure 2 The atomizer 100 also includes a sealing element 40 disposed in the main housing 11. The sealing element 40 is used to seal the liquid storage chamber 113. The sealing element 40 can be any of the flexible materials such as silicone, rubber or latex. The sealing element 40 can achieve the sealing of the liquid storage chamber 113 by elastically abutting against the inner wall of the main housing 11, so as to prevent the liquid matrix in the liquid storage chamber 113 from leaking and allow the liquid matrix in the liquid storage chamber 113 to flow out according to the preset path.

[0031] like Figure 2 and Figure 3As shown, the seal 40 is provided with a through hole 41 for the tubular body to pass through, and a first groove 42 extending into the through hole 41. The opening of the first groove 42 faces the liquid storage cavity 113 to receive the liquid matrix. The first groove 42 can serve as a first fluid channel to guide the liquid matrix toward the through hole 41. The tubular body 20 is configured to rotate relative to the seal 40 between a first position and a second position. When the tubular body 20 rotates relative to the seal 40 to the first position, the first opening 21 is aligned and connected with the first fluid channel, such as... Figure 2 As shown, the liquid matrix in the storage chamber 113 can enter the tubular body 20 through the first fluid channel and the first opening 21, and then flow into the atomizing assembly 30 for atomization, as shown. Figure 2 The liquid flow path R1 is shown in the diagram; and when the tubular body 20 rotates relative to the seal 40 to the second position, the first opening 21 and the first fluid channel are offset from each other, as shown in the diagram. Figure 4 As shown, the first opening 21 abuts against the wall of the through hole 41 and is then sealed by the sealant 40, preventing the liquid matrix from entering the tubular body 20.

[0032] Therefore, when a user needs to use the atomizer 100 for inhalation, the user can operate the tubular body 20 to rotate from the second position to the first position relative to the seal 40, so that the liquid matrix is ​​introduced into the atomizing component 30 for atomization, and the user can inhale the aerosol by inhaling through the mouthpiece 1111; when the user finishes using it, the user can operate the tubular body 20 to rotate back from the first position to the second position relative to the seal 40, so as to avoid the liquid matrix in the liquid storage chamber 113 from being in continuous communication with the atomizing component 30 when the atomizer 100 is idle, thereby reducing the probability of leakage when the atomizer 100 is idle.

[0033] It should be noted that the first fluid channel is not limited to the structure of the first groove 42. For example, a liquid guide hole connecting the liquid storage chamber 113 and the through hole 41 can also be provided inside the seal 40, and the liquid guide hole can serve as the first fluid channel.

[0034] Furthermore, the tubular body 20 may not rotate relative to the seal 40; for example, the tubular body 20 may move linearly relative to the seal 40 in the longitudinal direction.

[0035] In some embodiments, to facilitate user operation of the tubular body 20, the atomizer 100 also includes a rotatable or linearly movable operating part exposed outside the housing 10. The operating part is fixedly connected to the tubular body 20, so that the user can drive the tubular body 20 to rotate or move linearly by operating the operating part.

[0036] In some embodiments, the operating part includes the bottom cover 12 described above. The bottom cover 12 is used to hold the tubular body 20 and can rotate relative to the housing 10. When the bottom cover 12 rotates, it can drive the tubular body 20 to rotate relative to the seal 40. By setting the bottom cover 12 as a rotatable operating part, on the one hand, there is no need to add an additional operating part to the atomizer 100, and on the other hand, the consistency of the appearance of the atomizer 100 can be maintained, avoiding the reduction of the aesthetics of the atomizer 100 due to the addition of an additional operating part.

[0037] In some embodiments, such as Figure 1 As shown, the bottom cover 12 exposes an electrical connection portion 121 for electrical connection with an external power supply mechanism. The electrical connection portion 121 includes a first electrical connection portion 1211 and a second electrical connection portion 1212. The first electrical connection portion 1211 is used to connect to the positive terminal of the power supply mechanism, and the second electrical connection portion 1212 is used to connect to the negative terminal of the power supply mechanism. Thus, the electrical energy of the power supply mechanism can be conducted to the atomizing component 30 through the electrical connection portion 121, and the atomizing component 30 can obtain the electrical energy required for atomization.

[0038] In some embodiments, such as Figure 1 As shown, the electrical connection 121 is constructed in a ring shape, and the electrical connection 121 and the bottom cover 12 have the same axis of rotation. Therefore, the position of the electrical connection 121 will not change due to the rotation of the bottom cover 12 during the rotation of the bottom cover 12. The user does not need to align the electrical connection 121 with the power supply mechanism. When the atomizer 100 is installed in the power supply mechanism in any direction, the electrical connection 121 can maintain electrical connection with the power supply mechanism.

[0039] In some embodiments, such as Figure 2 and Figure 7 As shown, the bottom cover 12 also includes a latching part 122. The main housing 11 is provided with a latching groove 114 that is adapted to the latching part 122. The latching groove 114 extends in the rotation direction, so that the latching part 122 is latched and connected to the latching groove 114, thereby connecting the main housing 11 and the bottom cover 12. Furthermore, the latching part 122 can also slide in the latching groove 114. When the user rotates the bottom cover 12, the latching part 122 can slide from one end of the latching groove 114 to the other end.

[0040] like Figure 7As shown, the slot 114 has a first inner wall 1141 and a second inner wall 1142 disposed opposite to each other in the rotation direction. The first inner wall 1141 is used to define a first position, and the second inner wall 1142 is used to define a second position. Specifically, when the user rotates the bottom cover 12 from the first position to the second position, the latching part 122 rotates synchronously from the first inner wall 1141 to the second inner wall 1142. When the latching part 122 rotates to abut against the second inner wall 1142, the second inner wall 1142 limits the latching part 122, preventing it from rotating further, thereby restricting the bottom cover 12 to the second position.

[0041] Similarly, when the user rotates the bottom cover 12 from the second position to the first position, the latching part 122 simultaneously rotates from the second inner wall 1142 to the first inner wall 1141. When the latching part 122 rotates to abut against the first inner wall 1141, the first inner wall 1141 limits the latching part 122, preventing it from rotating further, thus restricting the bottom cover 12 to the first position. In some embodiments, such as Figure 2 and Figure 5 As shown, the tube wall of the tubular body 20 is also provided with a second opening 22 communicating with the atomizing component 30. The second opening 22 and the first opening 21 are spaced apart along the length of the tubular body 20, and the second opening 22 is used to allow external air to flow through. Correspondingly, the sealing member 40 is provided with a second groove 43 for external air to flow through. The second groove 43 communicates with the through hole 41, and the second groove 43 can serve as a second fluid channel to guide external air toward the through hole 41. Furthermore, when the tubular body 20 rotates relative to the sealing member 40 to the first position, the first opening 21 communicates with the first fluid channel, and the second opening 22 communicates with the second fluid channel, as shown. Figure 2 As shown, external air enters the atomizer 100 through the air inlet 123, then enters the second fluid channel, and then enters the tubular body 20 through the second opening 22, carrying the aerosol released in the tubular body 20 along the tubular body 20 to the mouthpiece 1111. Figure 2 As shown in the airflow transmission path R2, the liquid matrix flows along path R1 to the atomizing component 30 for atomization.

[0042] When the tubular body 20 rotates relative to the seal 40 to the second position, the first opening 21 is offset from the first fluid channel, and the first opening 21 abuts against the wall of the through hole 41, thus being sealed by the seal 40; similarly, the second opening 22 is offset from the second fluid channel, and the second opening 22 abuts against the wall of the through hole 41, thus also being sealed by the seal. Figure 4As shown. In this way, when the atomizer 100 is idle, the user can rotate the tubular body 20 relative to the seal 40 to the second position. At this time, the air path and liquid path of the atomizer 100 are blocked at the same time. On the one hand, this can prevent the liquid matrix from being continuously connected to the atomizing component 30 when the atomizer 100 is idle, which can easily lead to leakage. On the other hand, since the air path is blocked, the airflow sensor cannot be triggered, so the atomizing component 30 cannot start heating. This can prevent the atomizing component 30 from starting heating when the liquid supply is insufficient, which would cause the atomizing component 30 to burn dry.

[0043] Similarly, the second fluid channel is not limited to the structure of the second groove 43. For example, a guide hole connecting the air inlet 123 and the through hole 32 can also be provided inside the seal 40, and the guide hole can serve as the second fluid channel.

[0044] To ensure that when the tubular body 20 rotates relative to the seal 40 to the first position, the first opening 21 and the second opening 22 are simultaneously connected to the first fluid channel and the second fluid channel, and that when the tubular body 20 rotates relative to the seal 40 to the second position, the first opening 21 and the second opening 22 are simultaneously offset from the first fluid channel and the second fluid channel. In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the seal 40 has an end face 44 for the liquid storage chamber 113 and an extension 45 extending from the end face 44 away from the liquid storage chamber 113 and parallel to the tubular body 20. A first fluid channel is provided on the side of the extension 45 near the end face 44, and a second fluid channel is provided on the side of the extension 45 away from the end face 44. The first fluid channel and the second fluid channel are arranged at intervals along the length direction of the extension 45.

[0045] In a specific embodiment, such as Figure 6 As shown, the extension 45 has a first end face 451 facing the liquid storage cavity 113 and a second end face 452 disposed opposite to the first end face 451. A first groove 42 is disposed on the first end face 451 to define a first fluid channel, and a second groove 43 is disposed on the second end face 452 to define a second fluid channel.

[0046] In some embodiments, such as Figure 2 As shown, when the tubular body 20 is rotated to the first position relative to the seal 40, the first opening 21 and the second opening 22 are both fully exposed in the first groove 42 and the second groove 43, so that the liquid matrix and external air can enter the tubular body 20 in sufficient quantities, which is beneficial to increasing the concentration of aerosol generated by the atomizing component 30.

[0047] In some embodiments, such as Figure 2As shown, the atomizer 100 also includes a support member 50 for providing support to the seal 40. The support member 50 is fixedly connected to the main housing 11, and the fixed connection method can be any one of the following: snap-fit ​​connection, key connection, threaded connection, or rivet connection. Figure 8 In the embodiment shown, the support member 50 is provided with a snap-fit ​​protrusion 53, and the main housing 11 is provided with a corresponding slot that matches the snap-fit ​​protrusion 53. The snap-fit ​​protrusion 53 is snapped into the slot, thereby fixing the support member 50 and the main housing 11 together, thereby restricting the movement of the seal 40.

[0048] The seal 50 is tightly fitted onto the support 50, thereby providing support for the seal 40 and positioning the seal 40 within the main housing 11. This prevents the seal 40 from shifting or deforming during the rotation of the tubular body 20. Shifting or deforming the seal 40 would cause the first opening 21 and the first fluid channel, as well as the second opening 22 and the second fluid channel, to misalign when the tubular body 20 rotates relative to the seal 40 to the first position.

[0049] In some embodiments, such as Figure 8 As shown, the support member 50 is provided with a plug groove 51 that is adapted to the extension 45. The extension 45 is inserted into the plug groove 51, which can further position the seal 40. This is beneficial to prevent the seal 40 from shifting or deforming during the rotation of the tubular body 20.

[0050] It is easy to understand that when there are multiple first openings 21 and second openings 22, such as... Figure 5 As shown, there are also multiple extensions 45, which are arranged at intervals along the circumference, and each extension 45 is inserted into a corresponding insertion slot 51.

[0051] Furthermore, in some embodiments, to shorten the time it takes for the liquid matrix to flow from the storage chamber 113 into the tubular body 20, four first openings 21 are included, and the four first openings 21 are evenly arranged circumferentially on the tubular body 20. Consequently, there are also four corresponding first grooves 42, with one first groove 42 corresponding to one first opening 21. The four first grooves 42 then enclose a cross shape, such as... Figure 3 As shown.

[0052] In some embodiments, such as Figure 2As shown, an airflow chamber 52 is provided between the bottom cover 12 and the support member 50. The airflow chamber 52 is connected to the air inlet 123 and the second fluid channel 43. When the tubular body 20 rotates to the first position relative to the seal member 40, the second fluid channel 43 and the second opening 22 are aligned and connected, so that external air enters the tubular body 20 through the air inlet 123, and then through the airflow chamber 52, the second fluid channel 43 and the second opening 22.

[0053] Alternatively, in some embodiments, the suction nozzle 1111 is separate from the main housing 11, and the suction nozzle 1111 is fixedly connected to the tubular body 20, so that the user can rotate the suction nozzle 1111, thereby causing the tubular body 20 to rotate relative to the seal 40.

[0054] One embodiment of this application also proposes an electronic atomizing device, which can be found in [reference needed]. Figure 9 As shown, it includes an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply mechanism 200 that supplies power to the atomizer 100.

[0055] In an alternative implementation, for example Figure 9 As shown, the power supply mechanism 200 includes a receiving cavity 270 disposed at one end along the length direction for receiving and accommodating at least a portion of the atomizer 100, and an electrical contact 230 exposed at least partially on the surface of the receiving cavity 270 for forming an electrical connection with the electrical connection portion 121 of the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated in the power supply mechanism 200, thereby supplying power to the atomizer 100.

[0056] A sealing element 260 is provided within the power supply mechanism 200, and this sealing element 260 divides at least a portion of the internal space of the power supply mechanism 200 to form the receiving cavity 270. Figure 9 In the preferred embodiment shown, the seal 260 is configured to extend along the cross-sectional direction of the power supply mechanism 200, and is preferably made of a flexible material such as silicone, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving cavity 270 from flowing into components such as the controller 220 and sensor 250 inside the power supply mechanism 200.

[0057] exist Figure 9 In the preferred embodiment shown, the power supply mechanism 200 further includes a battery cell 210 for power supply located at the other end of the receiving cavity 270 along the length direction; and a controller 220 disposed between the battery cell 210 and the receiving cavity 270, the controller 220 being operable to guide current between the battery cell 210 and the electrical contact 230.

[0058] In use, the power supply mechanism 200 includes a sensor 250 for sensing the suction airflow generated when inhaling through the atomizer 100, and then the controller 220 controls the battery cell 210 to output current to the atomizer 100 according to the detection signal of the sensor 250.

[0059] Further in Figure 9 In the preferred embodiment shown, the power supply mechanism 200 is provided with a charging interface 240 at the other end away from the receiving cavity 270 for charging the battery cell 210.
