Atomiser and electronic atomising device

Abstract

The application discloses an atomizer and an electronic atomization device. The atomizer comprises an atomization assembly and a shell. The atomization assembly is used for generating aerosol. The shell has a second air channel and a mounting groove in communication. The aerosol generated by the atomization assembly is delivered to the second air channel. The mounting groove is used for mounting a liquid absorbing member. The liquid absorbing member has a first air channel for communication with the second air channel. The bottom surface of the mounting groove is provided with a convex structure for abutting against the inner surface of the liquid absorbing member. The convex structure has a certain height. The position where the condensed liquid is absorbed by the liquid absorbing member is higher than the bottom of the liquid absorbing member. Therefore, the bottom of the liquid absorbing member will not store too much condensed liquid. Thus, after the liquid absorbing member is pulled out of the mounting groove, the residual condensed liquid in the mounting groove is less, and the mounting groove is easy to clean. Meanwhile, the setting of the convex structure reduces the probability that the aerosol in the first channel directly contacts the inner surface of the liquid absorbing member. In this way, the probability that the aerosol is directly absorbed by the liquid absorbing member is also reduced, so that the loss of the taste of the aerosol is reduced.

[0002] Electronic atomizing devices use heating to heat the atomizing matrix to produce aerosol. Related technologies include electronic atomizing devices with a filter at the outlet for filtering the aerosol and absorbing condensate, which is fixed in place by a filter socket on the device body. However, after prolonged use, some condensate can remain at the bottom of the filter, making cleaning difficult and potentially contaminating the aerosol's taste during inhalation. Utility Model Content

[0003] The technical problem to be solved by this application is to provide an improved atomizer and electronic atomization device, addressing at least one of the deficiencies mentioned in the background art.

[0004] In some embodiments, an atomizer is provided, comprising an atomizing component and a housing; the atomizing component is used to generate an aerosol; the housing has a second air passage and a mounting groove connected together, the aerosol generated by the atomizing component being delivered to the second air passage; the mounting groove is used to mount a liquid suction element, the liquid suction element having a first air passage connected to the second air passage; wherein, the bottom surface of the mounting groove is provided with a protruding structure, the protruding structure being used to abut against the inner surface of the liquid suction element.

[0005] In some embodiments, the protrusion structure includes an annular boss surrounding the opening of the second airway near one end of the first airway.

[0006] In some embodiments, the lateral dimension of the opening of the first airway near the end of the second airway is equal to the lateral dimension of the protrusion structure.

[0007] In some embodiments, the liquid suction member includes a first end and a second end opposite to each other, the first end being embedded in the mounting groove, the second end extending out of the mounting groove, and the first air passage penetrating the end faces of the first end and the second end.

[0008] In some embodiments, the atomizer further includes a sealing seat that is sealed to the housing, and the atomizing assembly includes an atomizing tube that is sealed to the sealing seat and the housing, respectively. The atomizing tube, the housing, and the sealing seat together define a reservoir for storing the atomized matrix.

[0009] In some embodiments, one end of the atomizing tube away from the sealing seat extends into the second air passage, and the outer peripheral surface of the atomizing tube is sealed to the inner peripheral wall of the second air passage.

[0010] In some embodiments, the atomizer further includes a seal located between the outer peripheral surface of the atomizing tube and the inner peripheral wall of the second air passage, wherein the atomizing tube is sealed to the inner peripheral wall of the second air passage via the seal.

[0011] In some embodiments, the housing includes a bent outer shell portion and an air guide portion, the sealing seat and the outer shell portion are sealed together, the air guide portion forms a second air passage and the mounting groove, the atomizing tube and the air guide portion are sealed together, and the atomizing tube, the air guide portion, the outer shell portion and the sealing seat together define the liquid storage chamber.

[0012] In some embodiments, the atomizing assembly further includes an atomizing core disposed inside the atomizing tube, the atomizing tube having a liquid guiding hole, the atomizing core being in fluid communication with the liquid storage chamber through the liquid guiding hole, and the atomizing core being used to heat and atomize the atomizing matrix to generate an aerosol.

[0013] In some embodiments, this application also provides an electronic atomizing device, which includes a power supply unit and an atomizer as described in any of the above embodiments, wherein the power supply unit provides power to the atomizing components of the atomizer.

[0014] According to the atomizer of the above embodiment, since the bottom surface of the mounting groove is provided with a raised structure, the raised structure is used to abut against the inner surface of the liquid suction element. The raised structure has a certain height, so the position where the condensate is absorbed by the liquid suction element is higher than the bottom of the liquid suction element. Therefore, excessive condensate will not accumulate at the bottom of the liquid suction element. As a result, after the liquid suction element is pulled out of the mounting groove, there is less condensate remaining in the mounting groove, making it easier to clean. At the same time, the setting of the raised structure reduces the probability of direct contact between the aerosol in the first channel and the inner surface of the liquid suction element. This also reduces the probability of the aerosol being directly absorbed by the liquid suction element, thereby reducing the loss of aerosol taste. Attached Figure Description

Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0034] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0035] Please see Figure 1 In some embodiments, this application provides an electronic atomizing device, which includes a power supply unit 4 and an atomizer. The atomizer has an atomizing component 1 for generating an aerosol / mist for inhalation by a user. The power supply unit 4 provides power to the atomizing component 1 of the atomizer.

[0036] Please see Figures 2 to 4 In some embodiments, this application provides an atomizer, which includes an atomizing component 1 and a housing 3.

[0037] The atomizing component 1 is used to generate aerosols / mist for users to inhale. Specifically, the atomizer also includes a liquid storage chamber 6, which stores a liquid aerosol generating matrix. The atomizing component 1 is in fluid communication with the liquid storage chamber 6 and can absorb the aerosol generating matrix from the liquid storage chamber 6, heating and atomizing the aerosol generating matrix to generate aerosols / mist.

[0038] The housing 3 has a connected second air passage 32 and a mounting groove 31. The aerosol / mist generated by the atomizing assembly 1 is delivered to the second air passage 32. Figures 5 to 8 As shown, the mounting slot 31 is used to mount the liquid suction component 2. In some embodiments, the liquid suction component 2 is detachably inserted into the mounting slot 31, that is, the liquid suction component 2 can be an accessory independent of the atomizer. Alternatively, in some other embodiments, the liquid suction component 2 can also be part of the atomizer. The liquid suction component 2 is at least partially embedded in the mounting slot 31. Figures 2 to 4 In the illustrated embodiment, one part of the liquid suction member 2 is embedded in the mounting groove 31, while the other part extends out of the mounting groove 31. However, in other embodiments, the liquid suction member 2 can also be completely embedded in the mounting groove 31, that is, the top surface of the liquid suction member 2 is flush with the plane of the opening of the mounting groove 31.

[0039] The suction element 2 has a first air passage 21, which connects to a second air passage 32. The first air passage 21 is used to discharge the aerosol / mist generated by the atomizing component 1. The aerosol / mist generated by the atomizing component 1 is transported to the first air passage 21 via the second air passage 32, and the aerosol / mist within the first air passage 21 is output from the end of the suction element 2 away from the second air passage 32. The user can suction from the end of the suction element 2 away from the second air passage 32. When the aerosol / mist flows through the first air passage 21, the water vapor carried in it comes into contact with the suction element 2. Because the aerosol / mist generated by the atomizing component 1 has a high temperature, condensate will form in the first air passage 21 after the temperature drops. The suction element 2 can be used to absorb the condensate, thereby preventing the user from inhaling the condensate during suction. Specifically, the suction element 2 can be made of fibrous material or other porous material with liquid adsorption properties. The suction element 2 can also be used to filter the aerosol / mist generated by the atomizing component 1.

[0040] like Figure 6 As shown, the bottom surface of the mounting groove 31 is provided with a protruding structure 33, which is used to abut against the inner surface of the liquid suction member 2. That is, when the liquid suction member 2 is installed in the mounting groove 31, the protruding structure 33 is located outside the opening of the second air passage 32 near the end of the first air passage 21, and extends into the first air passage 21, so that the outer surface of the protruding structure 33 abuts against the inner surface of the liquid suction member 2.

[0041] Figure 6 The dotted line with a one-way arrow indicates the flow path of the condensate. Under the influence of gravity, the condensate generated in the first air passage 21 flows downwards along the first passage 21. The condensate flows downwards to the upper surface of the protruding structure 33 and temporarily accumulates there, then gradually moves towards the interior of the suction member 2 and is absorbed by the suction member 2. Thus, the condensate is reabsorbed into the interior of the suction member 2, thereby reducing the risk of condensate mixing into the airflow and affecting the aerosol's taste. Because the protruding structure 33 has a certain height, the position where the condensate is absorbed by the suction member 2 is higher than the bottom of the suction member 2, so that too much condensate will not accumulate at the bottom of the suction member 2. Therefore, after the suction member 2 is pulled out of the mounting groove 31, there is less condensate remaining in the mounting groove 31, making it easier to clean. At the same time, the setting of the protruding structure 33 reduces the probability of direct contact between the aerosol in the first passage 21 and the inner surface of the suction member 2, thus reducing the probability of the aerosol being directly absorbed by the suction member 2, thereby reducing the loss of aerosol taste.

[0042] Furthermore, after the protruding structure 33 extends into the first air passage 21, it covers the bottom area of ​​the inner periphery of the first air passage 21 (that is, the bottom area of ​​the inner periphery of the liquid suction member 2). Figure 6As shown, region C1 is the area within the first air passage 21 covered by the protruding structure 33, and region C2 is the area within the first air passage 21 not covered by the protruding structure 33, thus directly contacting the aerosol / mist. Because the bottom area of ​​the inner periphery of the first air passage 21 is blocked by the protruding structure 33 and does not directly contact the aerosol / mist, the generation of condensate in the bottom area of ​​the liquid suction element 2 is reduced.

[0043] like Figures 6 to 8 As shown, in some embodiments, the protrusion structure 33 includes an annular boss surrounding the opening of the second air passage 32 near the end of the first air passage 21. Condensate generated in the area of ​​the inner circumference of the first air passage 21 that is in direct contact with the aerosol / mist flows downwards to the upper surface of the annular boss for temporary accumulation, and then is gradually re-absorbed into the interior of the suction member 2 towards its interior. The annular boss can be a continuous annular boss or an annular boss with discontinuities / spaces. A continuous annular boss refers to an annular boss whose cross-sectional profile is a continuous, closed ring; an annular boss with discontinuities / spaces refers to an annular boss whose cross-sectional profile is a discontinuous, unclosed ring with several discontinuities / spaces in the annular profile. Further, please refer to... Figure 4 In some embodiments, the lateral dimension W1 of the opening of the first air passage 21 near the second air passage 32 is equal to the lateral dimension W2 of the protruding structure 33. The lateral dimension W2 of the protruding structure 33 is also the lateral dimension of the outer ring of the annular boss. This ensures that the protruding structure 33 can just extend into the first air passage 21 and abut against the inner circumference of the first air passage 21.

[0044] Such as 4 and Figure 6 As shown, in some embodiments, the lateral dimension W3 of the mounting groove 31 is greater than the lateral dimension W4 of the opening of the second air passage 32 near the end of the first air passage 21. Thus, the mounting groove 31 is wider, and the opening of the second air passage 32 near the end of the first air passage 21 is smaller, forming a stepped structure. The bottom surface of the suction member 2 can abut against the bottom surface of the mounting groove 31. The maximum lateral dimension of the suction member 2 can be equal to or slightly larger than the lateral dimension W3 of the mounting groove 31, so that the portion of the suction member 2 embedded in the mounting groove 31 is tightly fitted against the wall surface of the mounting groove 31, fixing the suction member 2 to the mounting groove 31. The end of the suction member 2 embedded in the mounting groove 31 is the bottom end, and the bottom end of the suction member 2 is located laterally between the protruding structure 33 and the inner circumferential surface of the mounting groove 31.

[0045] Such as 3 and Figure 4As shown, in some embodiments, the length of the suction member 2 is greater than the depth of the mounting groove 31. The suction member 2 includes a first end and a second end opposite to each other. The first end is embedded in the mounting groove 31, and the second end extends out of the mounting groove 31. The first air passage 21 passes through the end faces of the first end and the second end. Alternatively, in other embodiments, the extension path of the first air passage 21 may also be in other forms.

[0046] like Figures 3 to 5 , Figure 9 As shown, in some embodiments, the atomizer further includes a sealing seat 5, which is sealed to the housing 3. The atomizing assembly 1 is fixed between the sealing seat 5 and the housing 3. The atomizing assembly 1 includes an atomizing tube 11, which, along with the housing 3 and the sealing seat 5, defines a liquid storage chamber 6 for storing the atomized matrix. Specifically, the housing 3 has an opening 34 at the end furthest from the mounting groove 31, and the sealing seat 5 is at least partially embedded in the opening 34, with the outer periphery of the sealing seat 5 and the inner periphery of the housing 3 sealingly fitted. In some embodiments, the sealing fit between the outer periphery of the sealing seat 5 and the inner periphery of the housing 3 can be achieved by a sealing ring or other sealing components, or by an interference fit.

[0047] like Figure 5 and Figure 6 As shown, further, one end of the atomizing tube 11 extends into the second air passage 32, and the outer peripheral surface of the atomizing tube 11 is sealed to the inner peripheral wall of the second air passage 32, thereby fixing the atomizing tube 11 and the housing 3. Further, in some embodiments, the atomizer also includes a sealing element 7, located between the outer peripheral surface of the atomizing tube 11 and the inner peripheral wall of the second air passage 32, through which the atomizing tube 11 is sealed to the inner peripheral wall of the second air passage 32. In some embodiments, the sealing element 7 and the atomizing tube 11 can be an integrally formed structure; for example, the sealing element 7 can be a sealing ring on the outer peripheral surface of the atomizing tube 11. Alternatively, in other embodiments, the sealing element 7 is a separately formed sealing ring, which is sleeved on the outer periphery of the atomizing tube 11. When the atomizing tube 11 is embedded in the second air passage 32, the sealing ring elastically abuts against the inner peripheral wall of the second air passage 32.

[0048] like Figures 3 to 5 As shown, in some embodiments, the housing 3 includes a bent outer shell portion 36 and an air guide portion. The connection between the outer shell portion 36 and the air guide portion is smoothly transitioned by an arc segment. An opening 34 is provided at the end of the outer shell portion 36 away from the air guide portion. The sealing seat 5 is in sealing contact with the outer shell portion 36 at the opening 34. The air guide portion forms a second air passage 32 and a mounting groove 31. The atomizing tube 11 and the air guide portion are sealed together, and the atomizing tube 11, the air guide portion, the outer shell portion 36, and the sealing seat 5 together define the liquid storage chamber 6.

[0049] like Figures 3 to 5 , Figure 9As shown, in some embodiments, the sealing seat 5 has a groove 51 on the side facing the air guide 35. The other end of the atomizing tube 11 is embedded in the groove 51 on the sealing seat 5, and the atomizing tube 11 and the groove 51 are sealed together. That is, the opposite ends of the atomizing tube 11 are sealed together with the air guide 35 of the housing 3 and the sealing seat 5, respectively, so that the outer peripheral surface of the atomizing tube 11, the inner wall surface of the housing 3, and the upper surface of the sealing seat 5 together define the liquid storage chamber 6.

[0050] like Figures 3 to 5 , Figure 9 As shown, in some embodiments, the atomizing assembly 1 further includes an atomizing core 12, which is disposed inside the cavity of the atomizing tube 11. The atomizing tube 11 has a liquid guiding hole, and the atomizing core 12 is fluidly connected to the liquid storage chamber 6 through the liquid guiding hole. The atomizing core 12 is used to heat and atomize the atomizing matrix to generate aerosol. Specifically, the atomizing core 12 is connected to the power supply unit 4. The atomizing core 12 can absorb the aerosol generating matrix in the liquid storage chamber 6 through the liquid guiding hole, and heat and atomize the aerosol generating matrix to generate aerosol / mist under energized conditions. The aerosol / mist generated at the atomizing core 12 is sent out through the cavity of the atomizing tube 11, the second air passage 32, and the first air passage 21, with the air outlet path as shown. Figure 3 As shown by the dashed line with the arrow in the middle.

[0051] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
