Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, specifically to an atomizer and an electronic atomization device. Background Technology

[0002] Electronic atomizing devices are a popular transitional product for smokers trying to quit. They work by vaporizing a liquid matrix that enters the atomizer, producing a vapor effect. However, in current technology, after receiving the atomizer, the user needs to remove the sealing element to expose the liquid guide hole in the tubular element, and then wait several minutes for the liquid matrix to seep into the element before atomization can begin. This time-consuming process results in a poor user experience. Furthermore, during transportation, because the liquid guide hole is blocked by the sealing element, the element remains dry. This increases the chance of the atomizing chip accidentally triggering during transport, potentially burning the element and severely affecting the taste. Therefore, there is room for improvement. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an atomizer and an electronic atomizing device, aiming to solve the problem of poor user experience caused by the drying of the pre-treatment liquid element.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] In a first aspect, this utility model provides an atomizer, including a main housing, the main housing having a proximal end and a distal end facing away from each other in the longitudinal direction, the proximal end being provided with an air inlet; the main housing is provided with:

[0006] A liquid storage chamber is used to store a liquid matrix;

[0007] A trachea is arranged extending from the inhalation port toward the distal end;

[0008] Atomizing component for atomizing the liquid matrix to generate an aerosol;

[0009] A bracket is disposed near the atomizing component, and an air intake channel is defined within the bracket.

[0010] Sealing elements, including:

[0011] The operating part has one end extending distally to penetrate and block the air intake passage, and the other end extending proximally and passing through the trachea to the outside of the inhalation port.

[0012] A sealing portion, the sealing portion being disposed around the air tube;

[0013] A breakable connecting portion is connected between the sealing portion and the operating portion, and the connecting portion is held between the air tube and the atomizing assembly;

[0014] The operating part is configured to be user-operable and removed from the atomizer via the inhalation port to open the channel and the air tube, and to cause the connecting part to be squeezed by the air tube to break, thereby detaching the sealing part from the operating part.

[0015] In one example, the support and the air tube are arranged at intervals along the longitudinal direction of the nebulizer, and the support and the air tube are coaxial.

[0016] In one example, the connection portion includes a first side facing the trachea, the trachea extending distally and abutting against the first side.

[0017] In one example, the trachea extends distally with at least one puncture portion abutting against the first side.

[0018] In one example, the operating portion is provided with at least one first flange that abuts against the inner wall surface of the air intake channel for scraping the liquid matrix from the inner wall of the air intake channel during the removal of the operating portion.

[0019] In one example, the sealing portion is provided with at least one second flange that abuts against the outer surface of the trachea.

[0020] In one example, the trachea has a stepped portion circumferentially arranged on its outer side, the sealing portion is arranged around the stepped portion, and the side of the sealing portion facing the proximal end abuts against the stepped portion.

[0021] In one example, it also includes:

[0022] A tubular element extends longitudinally around the atomizing assembly, and the tubular element has liquid guiding holes arranged on its tube wall for the liquid matrix to flow through.

[0023] The sealing portion extends to include a sleeve portion, which surrounds the tubular element in the region above the liquid guiding hole.

[0024] In one example, the sealing portion is clamped between the tubular element and the trachea.

[0025] Secondly, this utility model also provides an electronic atomization device, including an atomizer for atomizing a liquid matrix to generate an aerosol, and a power supply device for supplying power to the atomizer; the atomizer includes the atomizer described in the above solution.

[0026] The atomizer and electronic atomizing device described in this utility model have the following advantages:

[0027] Before the sealing element is removed by the user, a portion of its operating part continuously blocks or seals the air intake channel, preventing the liquid matrix from leaking out of the support. Furthermore, because the liquid guiding element in the atomizing assembly is constantly soaked in the liquid matrix flowing in from the guiding orifice, it remains saturated, preventing burnt even from accidental triggering. Simultaneously, because a portion of the operating part, along with the sealing and connecting parts, blocks or seals the air tube, outside air cannot enter the atomizer from the air tube, preventing air from deteriorating the liquid matrix wetting the guiding element. Additionally, the sealing part surrounding the air tube prevents the liquid matrix stored in the reservoir from flowing into the air tube. When the user operates the operating part exposed outside the atomizer, the connecting part is punctured by the air tube, separating the operating part from the sealing part. The sealing element can then be removed, and the atomizer is ready for use. Since the guiding element remains saturated, there is no need to wait for it to become soaked, improving the user experience. Attached Figure Description

[0048] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] One embodiment of this application provides an electronic atomizing device, which can be found in [reference needed]. Figure 1 As shown, it includes an atomizer 1 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply device 10 that supplies power to the atomizer 1.

[0050] In an alternative implementation, for example Figure 1 As shown, the power supply device 10 includes a sub-housing 101, a battery cell 102 housed in the sub-housing 101 for power supply, and a controller 103 housed in the sub-housing 101, which is operable to guide current between the battery cell 102 and the atomizer 1.

[0051] In some optional embodiments, the power supply device 10 in use also includes a sensor 104 for sensing the suction airflow generated when the atomizer 1 is inhaled, and then the controller 103 controls the battery cell 102 to supply power to the atomizer 1 according to the detection signal of the sensor 104.

[0052] Further in Figure 1 In the preferred embodiment shown, the power supply device 10 also has a charging interface 105 in the sub-housing 101 for charging the battery cell 102.

[0053] Figures 2 to 9 The embodiments are shown Figure 1 A schematic diagram of the structure of one embodiment of the atomizer 1 includes:

[0054] Main casing 2; according to Figures 2 to 5 As shown, the main housing 2 is generally flat and cylindrical; the main housing 2 has a proximal end 22 and a distal end 23 that are opposite to each other in the longitudinal direction; wherein, according to the needs of normal use, the proximal end 22 is configured as the end for the user to inhale aerosol, and an air inlet 24 for the user to inhale is provided at the proximal end 22; while the distal end 23 is the end that is connected to the power supply device 10, and the distal end 23 of the main housing 2 is an open end 25, on which a removable end cap 8 is installed, the open end 25 structure is used to install various necessary functional components inside the main housing 2.

[0055] The end cap 8 is also provided with an air inlet 82, which is used to allow external air to enter into the atomizer 1 during suction.

[0056] See further Figures 2 to 5 As shown, the main housing 2 has a liquid storage chamber 21 for storing a liquid matrix, and an atomizing assembly for drawing the liquid matrix from the liquid storage chamber 21 and heating and atomizing the liquid matrix. The atomizing assembly typically includes a liquid guiding element 7 for drawing the liquid matrix, and a heating element 3 combined with the liquid guiding element 7. When energized, the heating element 3 heats at least a portion of the liquid matrix of the liquid guiding element 7 to generate an aerosol.

[0057] In an optional implementation, the liquid guiding element 7 includes flexible fibers, such as cotton fibers, non-woven fabrics, fiberglass ropes, etc., or includes porous materials with microporous structures, such as porous ceramics; the heating element 33 may be attached to the liquid guiding element 7 by means of printing, deposition, sintering or physical assembly, or wrapped around the liquid guiding element 7.

[0058] Further in Figures 2 to 5 In the specific implementation shown, the main housing 2 is provided with an air tube 26 extending from the proximal end 22 toward the distal end 23.

[0059] In specific implementation, the tubular element 5 is an independent component, preferably made of a thin, rigid material, such as ceramic or stainless steel; the air tube 26 is integrally molded with the main housing 2 from a moldable material.

[0060] And in Figures 2 to 5 In the illustrated embodiment, the liquid storage cavity 21 defined within the main housing 2 is closed by the main housing 2 at its proximal end 22; while the end of the liquid storage cavity 21 facing the distal end 23 is open 25. Furthermore, according to... Figures 2 to 5 As shown, atomizer 1 also includes:

[0061] The flexible sealing seat 9 serves two purposes: firstly, to seal the open end 25 of the liquid storage chamber 21 facing the distal end 23; secondly, to provide a seal between the end cap 8 and the main housing 2 to prevent leakage of the liquid matrix. For specific construction details, see [link to relevant documentation]. Figure 9 As shown, the flexible sealing seat 9 includes:

[0062] The main housing 2 has a peripheral sidewall 91 and a closed portion 92 located within the peripheral sidewall 91; a gap space exists between the main housing 2 and the peripheral sidewall 91, which is open on the side facing the end cap 8. During assembly, the end cap 8 is inserted into or extends into the gap space to abut against it. After assembly, the end cap 8 partially surrounds or encloses the peripheral sidewall 91 and is supported from the outside by the end cap 8 to provide a seal between the end cap 8 and the main housing 2.

[0063] See Figure 9 As shown, the end cap 8 is also provided with a longitudinally extending extension arm 81; the extension arm 81 protrudes relative to the rest of the end cap 8. The extension arm 81 is basically an elongated cylindrical shape. The surface of the extension arm 81 is provided with axially extending air grooves 811.

[0064] Correspondingly, the sealing seat 9 is provided with a through hole 93 that extends through or to the upper end face; after assembly, the extension arm 81 is inserted into or extends into the through hole 93, and a ventilation channel for allowing external air to enter the liquid storage chamber 21 is defined by the air groove 811 and the inner surface of the through hole 93. This is so that when the negative pressure in the liquid storage chamber 21 exceeds the threshold, the external air entering through the air inlet can enter the liquid storage chamber 21 through the ventilation channel defined by the air groove 811, thereby relieving the negative pressure in the liquid storage chamber 21.

[0065] In some variations, the air groove 811 is formed on the inner wall of the through hole 93; accordingly, the air exchange channel is defined between the air groove 811 on the inner wall of the through hole 93 and the extension arm 81.

[0066] The end cap 8 is fixedly connected to the sub-housing 101 through a sealing ring, thereby combining the atomizer 1 and the power supply device 10 together.

[0067] See further Figures 2 to 5 As shown, the tubular element 5 contains and is equipped with an atomizing component, and the tubular element 5 is provided with a plurality of liquid guiding holes 51 arranged circumferentially to allow the liquid storage chamber 21 to enter the atomizing component; thereby the atomizing component is in fluid communication with the liquid storage chamber 21 through the liquid guiding holes 51 to receive the liquid matrix.

[0068] And further see Figures 2 to 5 As shown, the atomizing component includes:

[0069] The liquid guiding element 7 is flexible in this embodiment; for example, it is made of flexible fibers such as cotton fibers, non-woven fabric, sponge, etc.; the liquid guiding element 7 is configured as a cylindrical shape arranged along the longitudinal direction of the main housing 2; the liquid guiding element 7 is coaxial with the tubular element 5 and is located inside the tubular element 5.

[0070] In implementation, the outer surface of the liquid guiding element 7 in the radial direction is either shielded from or connected to the liquid guiding hole 51. Therefore, the outer surface of the liquid guiding element 7 is configured as a liquid-absorbing surface to receive and absorb the liquid matrix from the liquid storage chamber 21 through the liquid guiding hole 51. The inner surface of the liquid guiding element 7 in the radial direction is configured as an atomizing surface, which is combined with / adhered to / abuts against the heating element 3. After the liquid matrix is ​​transferred to the atomizing surface, it is heated and atomized by the heating element 3 to generate an aerosol and released.

[0071] Furthermore, in this embodiment, the heating element 3 is configured to extend longitudinally along the main housing 2 / liquid guiding element 7; the heating element 3 is arranged coaxially with the liquid guiding element 7. The heating element 3 includes a first end 31 near the proximal end 22 and a second end 32 near the distal end 23.

[0072] The heating element 3 is defined by a side opening extending in the circumferential or longitudinal direction; the heating element 3 has electrode portions 33 located on both sides of the side opening, a mesh-like resistive heating portion 34 extending between the electrode portions 33, and conductive leads 35 connected to the electrode portions 33, and the heating element 3 is electrically connected to the battery cell 102 through the conductive leads 35.

[0073] The heating element 3 is formed by winding a mesh substrate; the wound heating element 3 is either a non-closed tube in the circumferential direction or a cylinder with a side opening in the longitudinal direction. Of course, the heating element 3 can have two electrode portions 33 and two conductive leads 35, one as the positive terminal and the other as the negative terminal. It should be noted that the heating element 3 can be a resistance heating mesh, a resistance heating coil, etc.

[0074] When powered, the heating element 3 generates Joule heat from the resistive heating portion 34 when direct current flows through it. The resistive heating portion 34 includes a heating section 343, a first tooth 341 extending from the heating section 343 toward the first end 31, and a second tooth 342 extending from the heating section 343 toward the second end 32. The heating section 343 primarily generates Joule heat when direct current flows through it, and the direct current mainly flows through the heating section 343. A smaller amount of current flows through the first tooth 341 and the second tooth 342, and the first tooth 341 and the second tooth 342 generate relatively little Joule heat, so that the heating area of ​​the resistive heating portion 34 is mainly located in the heating section 343.

[0075] And further according to Figures 2 to 5 As shown, it also includes a bracket 4, at least a portion of which is positioned inside the heating element 3 and surrounded by the heating element 3, thereby providing support for the heating element 3 from the inside of the heating element 3. An air intake channel is defined inside the bracket 4.

[0076] The sealing seat 9 has a through countersunk hole 94 at the through hole 93 position, and the bracket 4 is installed in the countersunk hole 94.

[0077] In some embodiments, the bracket 4 includes a support portion 41, which is positioned inside and surrounded by the heating element 3, thereby providing support for the heating element 3 from the inside. An air intake channel is defined within the support portion 41. Specifically, the support portion 41 is positioned inside and surrounded by the second tooth portion 342, thereby providing support for the second tooth portion 342 from the inside. This completes the support of the bracket 4 for the heating element 3. Simultaneously, since the second tooth portion 342 generates less Joule heating, its impact on the heating element 3 heating the liquid matrix is ​​minimal.

[0078] Furthermore, the bracket 4 also includes a stop portion 42 exposed outside the heating element 3, the stop portion 42 abutting against the liquid guiding element 7 to provide stop, and an air inlet channel is defined within the stop portion 42.

[0079] And further according to Figures 2 to 6 As shown, it also includes a sealing element 6, comprising:

[0080] The operating part 61 has one end extending to the distal end 23 and extending into the air intake passage to block the air intake passage, and the other end extending to the proximal end 22 and passing through the trachea 26 to the outside of the inhalation port 24.

[0081] A sealing portion 62 is arranged around the air tube 26;

[0082] A breakable connecting portion 63 is connected between the sealing portion 62 and the operating portion 61, and the connecting portion 63 is held between the air tube 26 and the atomizing assembly.

[0083] The operating part 61 is configured to be removed from the atomizer 1 by the user through the air inlet 24 to open the channel and air tube 26, and to cause the connecting part 63 to be squeezed by the air tube 26 to break and release the connection between the sealing part 62 and the operating part 61.

[0084] The exposed section of the operating part 61 is the part of the operating part 61 that passes through the air intake 24 and is exposed outside the main housing 2. When removing the sealing element 6, the user can grab the exposed section and pull it to remove the operating part 61 of the sealing element 6.

[0085] Before the sealing element 6 is removed by the user, a portion of the operating part 61 of the sealing element 6 continuously blocks or seals the air intake channel, preventing the liquid matrix from leaking out of the support 4. Furthermore, because the liquid guiding element 7 in the atomizing assembly is constantly immersed in the liquid matrix, it remains saturated, preventing burnt liquid guiding element 7 even if accidentally triggered. Simultaneously, because a portion of the operating part 61, along with the sealing part 62 and the connecting part 63, blocks or seals the air tube 26, outside air cannot enter the atomizer 1 through the air tube 26, thus preventing the liquid matrix soaking the liquid guiding element 7 from deteriorating. In addition, the sealing part 62 surrounding the air tube 26 also prevents the liquid matrix stored in the liquid storage chamber 21 from flowing into the air tube 26. When the user pulls on the exposed section of the operating part 61, the connecting part 63 is punctured by the air tube 26, separating the operating part 61 from the sealing part 62. Since the liquid guiding element 7 remains saturated, it can be used immediately after removing the sealing element 6, without waiting for the liquid guiding element 7 to become soaked, improving the user experience.

[0086] It should be noted that in some embodiments, the thickness of the connecting portion 63 can be set to be less than the thickness of the sealing portion 62, thereby reducing the structural strength of the connecting portion 63 and making it more prone to breakage when the user operates the operating portion 61. In other embodiments, the connecting portion 63 is provided with a weak portion, and the thickness of the connecting portion 63 in the weak portion region is less than the thickness in other regions, thereby reducing the structural strength of the connecting portion 63 in the weak portion and making it more prone to breakage when the user operates the operating portion 61. The weak portion can be an annular recess, a dotted recess, or a blocky recess.

[0087] like Figures 2 to 5 As shown, in an optional embodiment, the support 4 and the air tube 26 are arranged at intervals along the longitudinal direction of the atomizer 1, and the support 4 and the air tube 26 are coaxial.

[0088] By setting the bracket 4 and the air tube 26 coaxially, it is convenient to install the operating part 63 of the sealing element 6 into the air intake channel inside the bracket 4 through the air tube 26. At the same time, when the user operates the operating part 61 of the sealing element 6, the operating part 63 can be pulled out of the air intake channel and the air tube 26 inside the bracket 4 and the air inlet 24 in one direction. Thus, the air intake channel, the inside of the atomizing component and the air tube 26 form an air intake channel. When the user inhales the aerosol, air enters the inside of the atomizing component from the air intake channel, thereby driving the aerosol generated by the atomizing component to flow to the air tube 26. After passing through the air tube 26, it enters the user's mouth through the air inlet 24.

[0089] like Figures 2 to 5 , Figure 7 As shown, the connecting portion 63 further includes a first side facing the trachea 26, the trachea 26 extending distally 23 and abutting against the first side. Furthermore, the trachea 26 extending distally 23 has at least one puncture portion 261, the puncture portion 261 abutting against the first side.

[0090] During the removal of the operating part 61, the connecting part 63 is first pierced by the puncture portion 261 extending from the air tube 26. As the user continues to pull the exposed section of the operating part 61, the opening of the pierced connecting part 63 gradually enlarges along the puncture portion 261 until the end face of the air tube 26, excluding the puncture portion 261, presses against the connecting part 63, causing the connecting part 63 to completely break. This completely separates the operating part 61 from the sealing part 62, and the operating part 61 is pulled out from the air tube 26, thus connecting the atomizing component to the air tube 26. The arrangement of multiple puncture portions 261 ensures the consistency of the breaking of the sealing element 6. The puncture portion 261 can be a sharp structure such as a spike or an arc-shaped cutter. Preferably, the air tube 26 extends distally to the 23 with two puncture portions 261, which are symmetrically distributed.

[0091] like Figures 2 to 4 , Figure 6 As shown, in some embodiments, the operating portion 61 is provided with at least one first flange 64 for scraping away the liquid matrix on the inner wall of the channel during the removal of the operating portion 61. Simultaneously, when the operating portion 61 is not removed, the first flange 64 can enhance the seal between the operating portion 61 and the support 4.

[0092] like Figures 2 to 4 , Figure 6 As shown, at least one second flange 65 is arranged on the sealing portion 62, and the second flange 65 is press-fitted with the outer side of the trachea 26. By setting the second flange 65 to press-fit with the outer side of the trachea 26, the sealing performance between the sealing portion 62 and the trachea 26 can be enhanced.

[0093] like Figures 2 to 5 , Figure 7As shown, a step portion 262 is provided circumferentially on the outer side of the trachea 26, and a sealing portion 62 is provided around the step portion 262, with the side of the sealing portion 62 facing the proximal end 22 abutting against the step portion 262.

[0094] By providing a step portion 262 circumferentially on the outer side of the trachea 26, the step portion 262 can act as a stop when the operating part 61 is pulled. The step portion 262 abuts against the end of the sealing part 62 facing the proximal end 22, thereby preventing the operating part 61 from disengaging and causing the sealing part 62 to move, which would result in the liquid matrix stored in the liquid storage chamber 21 leaking out of the trachea 26.

[0095] like Figures 2 to 6 As shown, in some embodiments, the sealing portion 62 extends to include a sleeve portion 66, which surrounds the tubular element 5 above the liquid guide hole 51. This further enhances the sealing performance between the air tube 26 and the tubular element 5. Furthermore, since the sleeve portion 66 extends from the sealing portion 62 and surrounds the tubular element 5, the sleeve portion 66 and the sealing portion 62 can provide a stop for the tubular element 5.

[0096] like Figures 2 to 6 As shown, the sealing portion 62 is clamped between the tubular element 5 and the air tube 26. By configuring the sealing portion 62 to be clamped between the tubular element 5 and the air tube 26, the sealing performance of the sealing element 62 is further improved, preventing aerosols from entering the liquid storage chamber 21, and also preventing liquid matrix from entering the air tube 26.

[0097] Preferably, the sealing element 6 is flexible, allowing the operating portion 61 and sealing portion 62 of the sealing element 6 to better seal the air tube 26, the atomizing assembly, and the channel. The material of the sealing element 6 can be silicone or other flexible materials.

[0098] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
