Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and in particular to an atomizer and its atomizing body. Background Technology

[0002] For existing electronic atomizing devices on the market, the atomizer base in the atomizer is generally assembled from multiple parts. Due to the superposition of multiple parts, the relative dimensional tolerances will also be superimposed, and the differences in assembly methods will result in many production processes for electronic atomizers. During the high-temperature atomization process of liquid aerosol generating matrix, the high-temperature atomized gas will form condensate due to various reasons. Over time, it will seep out to the outside of the atomizer through the tiny gaps between the parts. The seeping condensate will adhere to the components of the electronic atomizing device, causing damage to the components (especially electronic components) and reducing the service life of the electronic atomizing device.

[0070] Figures 1 to 12 An atomizer 1 according to a first embodiment of the present invention is shown. The atomizer 1 includes a housing 10 and an atomizing body 20 disposed inside the housing 10. In some embodiments, a liquid storage space 30 for storing a liquid aerosol generating matrix and a gas guiding channel 40 for discharging the atomized liquid aerosol generating matrix (i.e., atomized gas) are defined between the housing 10 and the atomizing body 20. The housing 10 is longitudinally elongated, and the atomizing body 20 is disposed inside the housing 10 along the longitudinal axis of the housing 10 for heating and atomizing the liquid aerosol generating matrix in the liquid storage space 30 into a gaseous aerosol. The housing 10 is used to contain and protect the atomizing body 20 and to discharge the atomized gas.

[0071] like Figure 2 and Figure 10As shown, in some embodiments, the liquid storage space 30 may include a liquid storage chamber 31 formed between the atomizing body 20 and the housing 10, and a liquid lowering channel formed within the atomizing body 20. The liquid storage chamber 31 is used to store the liquid aerosol generation matrix, and the liquid lowering channel is used to transport the liquid in the liquid storage chamber 214 to the atomizing assembly 13. The air guiding channel 40 may include an air outlet channel 41 formed inside the housing 10 and an air inlet channel 42 formed inside the atomizing body 20. The air outlet channel 41 and the air inlet channel 42 are connected to allow air to circulate within the atomizer 1, and to transport the mixture of atomized gas and air formed in the atomizing body 20 to the outside of the atomizer 1 along the air outlet channel 41.

[0072] like Figure 2 , Figure 3 and Figure 9 As shown, in some embodiments, the housing 10 has a flat cross-section, including an outer wall surface 11 and an inner wall surface 12. One end of the outer wall surface 11 has a lower opening 111 for inserting and fixing the atomizing body 20. The upper end of the inner wall surface 12 connects to the upper end of the outer wall surface 11 and has an upper opening 121 for venting the atomized gas. In some embodiments, the inner wall surface 12 extends from the upper opening 121 to the lower opening 111 and has a connecting portion 122 at its end for engaging and fixing with the atomizing body 20. The connecting portion 122 has a connecting port 1221 for communicating with the atomizing body 20 to vent the atomized gas formed within it.

[0073] It should be understood that a channel extending from the connection port 1221 to the upper opening 121 is formed inside the inner wall surface 12 of the housing, which is the gas outlet channel 41, used to exhaust the mixed gas formed inside the atomizing body 20. The liquid storage chamber 31 is formed between the outer wall surface 11 of the housing, the inner wall surface 12 of the housing, and the atomizing body 20. In some embodiments, the material of the housing 10 includes plastic.

[0074] like Figure 2As shown, in some embodiments, the atomizing body 20 may be symmetrical on the front and rear sides, and also on the left and right sides, to facilitate molding and subsequent assembly. The atomizing body 20 may include an atomizing base 21, an atomizing component 23, a sealing component 22, and an adjusting member 24. The atomizing base 21 is used to accommodate the atomizing component 23 and forms an atomizing chamber 216, providing space for the atomized aerosol to mix with air. The atomizing component 23 is disposed within the atomizing base 21 and is used to heat the liquid aerosol generating matrix to atomize it. The sealing component 22 is disposed on the atomizing base 21 and is used to seal the atomizer 1 to prevent the liquid aerosol generating matrix from flowing out. The adjusting member 24 is movably disposed within the atomizing base 21 and, together with the atomizing base 21, defines an air intake channel 42. In some embodiments, the air intake channel 42 can be operably opened or closed. It is understood that the atomizing body 20 is not limited to a symmetrical structure; an asymmetrical structure may also be applicable. In some embodiments, the atomizing chamber 216 is connected to the air outlet channel 41 for air delivery.

[0075] See also Figure 4 and Figure 5 In some embodiments, the atomizing base 21 is cylindrical with an elliptical cross-section, comprising an upper base 211, a lower base 212, a first support portion 213, and a second support portion 214. These components are integrally formed, reducing the number of parts, achieving extreme simplification, ensuring stability and reliability, and lowering component and assembly costs. Specifically, the first support portion 213 and the second support portion 214 are spaced apart between the upper base 211 and the lower base 212, defining a receiving cavity 215 and an atomizing cavity 216. The receiving cavity 215 houses part of the atomizing component 23, and the atomizing cavity 216, located at the lower end of the receiving cavity 215, is used to mix the atomizer with externally drawn air and carry away the mixed air. In some embodiments, the atomizing base 21 is made of plastic.

[0076] In some embodiments, the upper seat 211 is generally cylindrical, symmetrical front to back and left to right, and its cross-section is adapted to the shape of the lower opening 111, forming a longitudinally elongated ellipse, which facilitates manufacturing and subsequent assembly. In some embodiments, the upper seat 211 may include an air vent 2111 and a first liquid guiding hole 2112 and a second liquid guiding hole 2113 formed on both sides of the air vent 2111. The air vent 2111, the first liquid guiding hole 2112, and the second liquid guiding hole 2113 are all longitudinally arranged, and the air vent 2111 is located at the center of the cross-section of the upper seat 211 and corresponds to the connection port 1221. The first liquid guiding hole 2112 and the second liquid guiding hole 2113 are symmetrically arranged on both sides of the air vent 2111.

[0077] Specifically, both the first liquid guiding hole 2112 and the second liquid guiding hole 2113 extend from the upper wall of the upper seat to the lower wall of the upper seat, and are in liquid guiding communication with the liquid storage tank 31, for guiding the liquid aerosol generation matrix in the liquid storage tank 31 into the interior of the atomizing body 20. The air outlet 2111 is used to communicate with the air outlet channel 41 to guide the mixed gas formed inside the atomizing seat 21. In some embodiments, the air outlet 2111 and the connecting part 122 are connected by an interference fit, so that the atomizing seat 21 is fixed inside the housing 10.

[0078] In some embodiments, the upper seat 211 further includes a first air guide hole 2114, which extends from one end face of the upper seat 211 containing the short axis of its cross-section to the other end face and communicates with an air outlet 2111. The air outlet 2111 extends from the upper wall of the upper seat to the first air guide hole 2114. In some embodiments, the upper seat 211 further includes a first sealing groove 2115, which is annular and formed on the side wall of the upper seat 211. The first sealing groove 2115 is used to accommodate some components in the sealing assembly 22 and to seal the housing 10 and the atomizing seat 21.

[0079] It should be understood that the first air guide hole 2114 is connected to the atomizing chamber 216 for air guiding, so that the atomizing chamber 216 is connected to the air outlet channel 41 through the first air guide hole 2114 and the air outlet hole 2111 for air guiding, and is used to export the mixed gas formed inside the atomizing chamber 216.

[0080] In some embodiments, the lower seat 212 is generally cylindrical, symmetrical front to back and left to right, and its cross-section is adapted to the shape of the cross-section of the upper seat 211, being an elongated ellipse, which facilitates manufacturing and subsequent assembly. An air inlet pipe 2121 is formed on the lower seat 212, extending from the upper end face to the lower end face, for connecting the atomizing chamber 216 to the outside. The adjusting member 24 is disposed in the air inlet pipe 2121 and, together with the air inlet pipe 2121, defines an air inlet channel 42. The air inlet channel 42 is in air-guiding communication with the atomizing chamber 216 for guiding outside air into the interior of the atomizing seat 21.

[0081] In some embodiments, the air intake duct 2121 is formed at the center of the lower seat 212, and the lower seat 212 further includes a first conductive hole 2122 and a second conductive hole 2123. The first conductive hole 2122 and the second conductive hole 2123 are symmetrically arranged on both sides of the air intake duct 2121 for accommodating some components in the atomizing assembly 23.

[0082] like Figure 5 and Figure 10As shown, the air intake duct 2121 includes a cylindrical sidewall and an upper wall adapted to the cylindrical sidewall. Specifically, the sidewall includes a first sidewall and a second sidewall disposed at the lower end of the first sidewall, wherein the diameter of the first sidewall is smaller than the diameter of the second sidewall. In some embodiments, a portion of the sidewall on the second sidewall is further recessed to form at least one air intake groove 2126. Specifically, there are two air intake grooves 2126, symmetrically formed on the second sidewall.

[0083] In some embodiments, at least one through-hole 2125 is formed on the upper wall surface, communicating with the air intake channel 42, and a limiting hole 2124 is formed at the center of the upper wall surface for limiting the adjustment member 24. In some embodiments, there are two air inlets 2125, symmetrically arranged on both sides of the limiting hole 2124.

[0084] In some embodiments, the lower seat 212 further includes a second sealing groove 2127, which is annular and formed on the outer side wall of the lower seat 212. It is used to cooperate with the first sealing groove 2115 to accommodate some of the components in the sealing assembly 22 and seal the housing 10 and the atomizing seat 21.

[0085] like Figure 2 and Figure 9 As shown, in some embodiments, the first support portion 213 and the second support portion 214 are both erected between the upper seat 211 and the lower seat 212, and are erected at both ends in the long axis direction of the cross-section of the atomizing seat, and are symmetrically distributed with the longitudinal axis of the atomizing seat 21 as the line of symmetry. Specifically, the first support portion 213 is provided with a first assembly portion 2131, and the second support portion 214 is provided with a second assembly portion 2141, and the first assembly portion 2131 and the second assembly portion 2141 are correspondingly arranged and cooperate to fix the atomizing component 23 in the receiving cavity 215.

[0086] In some embodiments, at least one first collection groove 2132 and at least one second collection groove 2142 are respectively formed on the sidewalls of the first support portion 213 and the second support portion 214, both used to collect condensate and prevent a large amount of condensate from flowing to the lower seat and, after a long period of time, seeping into the outside of the atomizer 1, causing poor electrical contact of the atomizer 1. In some embodiments, the first collection groove 2132 and the second collection groove 2142 can be provided simultaneously or separately.

[0087] It should be understood that after the liquid aerosol generating matrix is ​​heated into atomized gas by the atomizing component 23, it will condense due to factors such as the decrease in temperature and blockage of the airflow channel during the upward discharge process. When the user uses the atomizer 1, the air flowing in the atomizer 1 will also generate a small amount of liquid moisture. The condensate mentioned above is the mixture of liquids generated by this condensation.

[0088] In some embodiments, the cross-sections of the atomizing base 21, the upper base 211, and the lower base 212 may also be of other shapes.

[0089] like Figure 2 As shown, in some embodiments, the sealing assembly 22 includes a first sealing ring 221 and a second sealing ring 222, wherein the first sealing ring 221 and the second sealing ring 222 are respectively disposed on the first sealing groove 2115 and the second sealing groove 2127, and respectively are interference-fitted with the first sealing groove 2115, the second sealing groove 2127 and the housing 10, for sealing the gap between the atomizing seat 21 and the housing 10.

[0090] like Figure 2 and Figure 8 As shown, in some embodiments, the atomizing component 23 includes a heating element 231, a second sealing element 232, a first conductive element 233, and a second conductive element 234. The heating element 231 has a heating cavity 2312 recessed downwards from its upper end surface. This heating cavity 2312 communicates with the first liquid guiding hole 2112 and the second liquid guiding hole 2113 for containing the liquid aerosol generating matrix. A heating element 2311 is disposed on the lower end surface of the heating element for heating the liquid aerosol generating matrix and atomizing it.

[0091] like Figure 2 and Figure 9 As shown in some embodiments, the second sealing member 232 is cylindrical, and the heating element 231 is longitudinally inserted inside the second sealing member 232 to protect the heating element 231 and expose the heating cavity 2312 and the heating element 2311 of the heating element 231. Specifically, the second sealing member 232 wraps around the periphery of the heating element 231, and symmetrical flanges 2321 for embedding the heating element 231 are formed on the inner wall surface. Correspondingly, grooves 2313 are provided on two opposite sides of the heating element 231. The flanges 2321 and the grooves 2313 cooperate with each other, so that the heating element 231 is embedded inside the second sealing member 232. On the one hand, it can play a sealing role to prevent the liquid aerosol generation matrix from leaking out, and on the other hand, it can also protect the heating element 231 from being crushed.

[0092] Refer to together Figure 9The heating element 231 is fixed in the receiving cavity 215 by engaging the second sealing member 232 onto the first assembly part 2131 and the second assembly part 2141. In some embodiments, a flange may be provided on the heating element 231 and a groove may be provided on the second sealing member 232 to achieve mutual engagement and fixation. During assembly, the heating element 231 and the second sealing member 232 only need to be laterally engaged in the receiving cavity 215 of the atomizing seat 21, simplifying the assembly process and saving assembly time.

[0093] It should be understood that the first liquid guide hole 2112 and the second liquid guide hole 2113 together form the aforementioned liquid discharge channel. This liquid discharge channel is connected to the liquid storage tank 31, allowing the liquid aerosol generation matrix in the liquid storage tank 31 to flow along the liquid discharge channel to the heating element 231 for heating and atomization.

[0094] In some embodiments, the first conductive element 233 is interference-fitted through the first conductive hole 2122, with both ends protruding from the first conductive hole 2122, for electrically connecting the heating element 231 to the power source. In some embodiments, the first conductive element 233 includes a first connecting portion 2331 and a second connecting portion 2332, wherein the first connecting portion 2331 is located at one end of the first conductive element 233 and is interference-fitted to one end of the heating element 2311 for electrical connection. The second connecting portion 2332 is located at the other end of the first conductive element 233 and is disposed on the lower end surface of the lower seat 212 for electrically connecting to the power source. In some embodiments, the lower end surface of the lower seat 212 is recessed inward to form a first mating surface, which is adapted to the shape of the second connecting portion 2332 for fitting and limiting.

[0095] In some embodiments, the second conductive element 234 is interference-fitted through the interior of the second conductive hole 2123, with both ends protruding from the second conductive hole 2123, for electrically connecting the heating element 231 to the power source. In some embodiments, the second conductive element 234 includes a third connecting portion 2341 and a fourth connecting portion 2342, wherein the third connecting portion 2341 is located at one end of the second conductive element 234 and is interference-fitted to the other end of the heating element 2311 for electrical connection. The fourth connecting portion 2342 is located at the other end of the second conductive element 234 and is disposed on the lower end surface of the lower seat 212 for electrically connecting to the power source. In some embodiments, the lower end surface of the lower seat 212 is partially recessed to form a second mating surface, which is adapted to the shape of the fourth connecting portion 2342 for fitting and limiting.

[0096] like Figure 6 and Figure 7As shown, in some embodiments, the adjusting member 24 is disposed in the air intake pipe 2121 and can move back and forth between a first position and a second position. When the adjusting member 24 is in the first position, it closes the air intake pipe 2121; when it is in the second position, it opens the air intake pipe 2121. When the adjusting member 24 closes the air intake pipe 2121, it can prevent damage to the equipment caused by leakage of the atomizer 1 under conditions such as high temperature environment or long-term storage, thereby improving the service life of the equipment.

[0097] In some embodiments, the first position and the second position are respectively located on the longitudinal axis of the intake pipe 2121. The adjusting member 24 is axially movable inside the intake pipe 2121 and includes a base 241, a cylindrical sidewall 242, a sealing part 243, and a limiting part 244. The base 241 is flat and cylindrical with a circular cross-section. The cylindrical sidewall 242 is erected on the upper end face of the base 241. The sealing part 243 is annular and is also located on the upper end face of the base 241, surrounding the lower end of the outer wall of the cylindrical sidewall 242. Specifically, the diameter of the base 241 is adapted to the diameter of the second sidewall in the intake pipe 2121, the diameter of the sealing part 243 is adapted to the diameter of the first sidewall, and it can be interference-fitted with the first receiving groove to ensure a seal. The diameter of the cylindrical sidewall 242 is smaller than the diameter of the first sidewall.

[0098] In some embodiments, a liquid storage chamber 246 is defined between the cylindrical sidewall 242 and the base 241. The liquid storage chamber 246 is in liquid-guiding communication with the atomizing chamber 216 and is used to collect and store condensate. It also prevents the condensate inside the first collection tank 2132 and the second collection tank 2142 from becoming saturated and flowing out of the lower body, thus facilitating cleaning.

[0099] In some embodiments, the limiting portion 244 is longitudinally elongated, erected axially on the upper wall of the base 2211, and passes through the interior of the liquid storage cavity 246. The limiting portion 244 also includes a head 2441 disposed at one end of the limiting portion 244. The head 2441 protrudes from the liquid storage cavity 246, bulges above the cylindrical sidewall 242, and passes through the limiting hole 2124. In some embodiments, the maximum radial dimension of the head 2441 is larger than the diameter of the limiting hole 2124, which is used to limit the adjusting member 24, restricting it to move only up and down along the axial direction of the atomizing seat 21, but preventing it from detaching from the atomizing seat 21, thus limiting the distance of movement.

[0100] In some embodiments, the adjusting member 24 is further provided with a control part 245, which is erected axially on the lower end surface of the base 241 and is used by the user to control the position of the adjusting member 24 in order to achieve the purpose of switching the atomizer 1 on and off.

[0101] It should be understood that the cylindrical sidewall 242 of the regulating component 24, together with the sidewall of the air intake pipe, defines the air intake channel 42, and is connected to the atomizing chamber 216 through two air intake holes 2125. This allows the air intake channel 42 to be connected to the air outlet channel 41 through the atomizing chamber 216. The air intake channel 42, the air outlet channel 41, and the atomizing chamber 216 together define the air guide channel 40, allowing external gas to flow from the air intake channel 42 into the atomizing chamber 216 and mix with the gaseous aerosol generating matrix to form a mixed gas, which is finally discharged from the air outlet channel 41. Figure 12 The arrows in the diagram indicate the direction of gas flow.

[0102] In specific usage, such as Figure 9 and Figure 10 As shown, the atomizer 1 is in the closed state. At this time, the sealing part 243 is locked inside the first side wall and is press-fitted with the first side wall to achieve a sealed state. The air intake channel 42 is closed, and the atomizer 1 cannot be used, which can prevent children from accidentally using it.

[0103] It should be understood that, since the sealing part 243 is tightly fitted to the first side wall, when the atomizer 1 is in the closed state, the adjusting part 24 is fixed in the above state and will not move to the open state due to its own gravity.

[0104] When it is necessary to turn on the atomizer 1, simply pull down the control unit 245 to move the adjusting member 24 downwards relative to the atomizer base 21. Figure 11 and Figure 12 As shown, the sealing part 243 moves from the state of interference fit with the first side wall to the position of the air intake pipe corresponding to the second side wall. At this time, the head 2441 is locked on the upper end face of the limiting hole 2124, the adjusting part 24 moves down to the limit position, the air intake channel 42 is opened, the air guide channel 40 is opened, and the atomizer 1 is in a usable state.

[0105] The design of the adjusting component 24 and the air intake pipe 2121 allows the atomizer 1 to be opened and closed at any time, preventing accidental use by children. It should be understood that opening and closing the air intake channel 42 is equivalent to opening and closing the air intake pipe 2121.

[0106] Figures 13 to 20 The second embodiment of the present invention is shown. The main difference between this embodiment and the first embodiment is that, in this embodiment, the upper seat 211 includes a base 2116, a first liquid guiding part 2117 and a second liquid guiding part 2118. The base 2116 is in the shape of a flat column with an elliptical cross-section, which is adapted to the cross-sectional shape of the lower seat 212 for easy installation.

[0107] In some embodiments, both the first liquid guiding portion 2117 and the second liquid guiding portion 2118 are columnar with arc-shaped cross-sections, and are respectively disposed at the two ends of the long axis of the upper surface of the base 2116. The two arcs are arranged opposite to each other and are adapted to the shapes of the two ends of the long axis of the cross-section of the base 2116. In some embodiments, a first sealing groove 2115 is formed on the side wall surface of the base 2116 for sealing the gap between the atomizing seat 21 and the housing 10.

[0108] like Figure 14 and Figure 15 As shown, in some embodiments, the atomizing base 21 further includes a receiving portion 217, which is cylindrical and extends axially through the base 2116 to receive the heating element 231. Specifically, the receiving portion 217 is longitudinally elongated, extending from the upper wall surface to the lower wall surface of the base 2116. An upper body protrudes from the upper wall surface of the base 2116 and is engaged with the connecting portion 122 of the housing 10, and communicates with the connecting port 1221. In some embodiments, the longitudinal axis of the receiving portion 217 coincides with the longitudinal axis of the base 2116.

[0109] It should be understood that the portion of the accommodating part 217 above the upper end face of the base 2116 forms a liquid guiding cavity around the first liquid guiding part 2117 and the second liquid guiding part 2118. The liquid guiding cavity is connected to the liquid storage chamber 31 inside the housing 10, and is used to allow the liquid aerosol generation matrix in the liquid storage chamber 31 to flow into the atomizing seat 21.

[0110] In some embodiments, the cylindrical receiving portion 217 includes a cylindrical side wall and a circular lower wall, with a columnar receiving groove 2171 formed between the side wall and the lower wall, and the heating element 231 disposed inside the receiving groove 2171. In some embodiments, at least one liquid discharge hole 2172 is also provided on the side wall, and there are two liquid discharge holes 2172 symmetrically arranged on the side wall and disposed at the upper end of the base 2116. The lower body of the lower body is connected to the upper end face of the base 2116, for communicating with the receiving groove 2171 and the liquid guiding cavity formed by the first liquid guiding portion 2117 and the second liquid guiding portion 2118, so that the liquid aerosol generation matrix flows to the heating element 231 for atomization.

[0111] It is understood that in this embodiment, the liquid guiding part 2117 and the liquid guiding part 2118 together define the liquid guiding cavity formed around the liquid guiding cavity, and the liquid lowering hole 2172 connected to the liquid guiding cavity defines the liquid lowering channel so that the liquid aerosol generation matrix can flow smoothly to the heating element 231 for atomization.

[0112] In some embodiments, the accommodating portion 217 further includes a second air guide hole 2173 formed on the lower wall surface of the accommodating portion 217. The longitudinal axis of the second air guide hole 2173 coincides with the longitudinal axis of the accommodating portion 217, and the diameter of the second air guide hole 2173 is smaller than the diameter of the heating element 231, for allowing gas to pass through. In some embodiments, the accommodating portion 217 is also provided with at least one ventilation hole 2174. Specifically, there are two ventilation holes 2174, symmetrically formed on the side wall surface of the accommodating portion 217, extending from the outer end face to the inner end face of the side wall surface, and formed on the side wall surface of the accommodating portion 217 located below the lower end face of the base 2116, for improving the flow state of the liquid aerosol generation matrix.

[0113] like Figure 14 and Figure 17 As shown, the atomizing base 21 also includes a first connecting portion 218 and a second connecting portion 219. The first connecting portion 218 and the second connecting portion 219 are symmetrically arranged on both sides of the receiving portion 217 and are both located at the lower end of the base 2116. The lower body of the first connecting portion 218 and the second connecting portion 219 is respectively provided with a first connecting groove 2181 and a second connecting groove 2191 for electrically connecting the heating element 2311 to the first conductive element 233 and the second conductive element 234, respectively. The first connecting portion 2331 of the first conductive element 233 is disposed in the first connecting groove 2181, and the third connecting portion 2341 of the second conductive element 234 is disposed in the second connecting groove 2191.

[0114] In some embodiments, the atomizing assembly 23 includes a heating element 231, a first conductive element 233, and a second conductive element 234, wherein the heating element 231 is arranged in a longitudinally elongated cylindrical shape, and its cross-sectional diameter is adapted to the receiving groove 2171. Figure 16 As shown, in some embodiments, the heating element 231 has a heating component 2311 inside, and the heating element 231 also has a first wire 2314 and a second wire 2315. One end of the first wire 2314 is electrically connected to one end of the heating component 2311, and the other end of the first wire 2314 is disposed in the first connecting groove 2181 and electrically connected to the first connecting portion 2331. One end of the second wire 2315 is electrically connected to the other end of the heating component 2311, and the other end of the second wire 2315 is disposed in the second connecting groove 2191 and electrically connected to the third connecting portion 2341.

[0115] It should be understood that the atomizing chamber 216 is connected to the internal air guide of the heating element 231 through the second air guide hole 2173, and is also connected to the air outlet channel 41.

[0116] Figure 17 and Figure 18The off state of atomizer 1 in this embodiment is shown. Figures 19 to 20 The on state of atomizer 1 in this embodiment is shown, and will not be described again here.

[0117] Figures 21 to 29 A third embodiment of the present invention is shown. The main difference between this embodiment and the first embodiment is that the air intake pipe 2121 includes a cylindrical side wall and an upper wall adapted to the cylindrical side wall. Specifically, the side wall includes a first side wall and a second side wall disposed at the lower end of the first side wall, wherein the diameter of the first side wall is smaller than the diameter of the second side wall. In some embodiments, a portion of the side wall on the second side wall is further recessed to form at least one air intake groove 2126. Specifically, there are two air intake grooves 2126, symmetrically formed on the second side wall. In some embodiments, an air intake hole 2125 is also formed on the upper wall, communicating with the air intake channel 42. Specifically, the air intake hole 2125 is formed at the center of the upper wall.

[0118] In some embodiments, at least one limiting protrusion 2128 is also provided on the second sidewall to limit the movement range of the adjusting member 24, so as to achieve the function of turning the atomizer 1 on and off. Specifically, there are two limiting protrusions 2128, which are disposed opposite to each other on the second sidewall, and their positions are not on the same axial direction as the positions of the two air inlet slots 2126.

[0119] Refer to together Figure 24 and Figure 25 The adjusting member 24 is disposed in the intake pipe 2121 and, together with the intake pipe 2121, defines an intake channel 42 with an adjustable gas flow rate. The adjusting member 24 can move back and forth around the longitudinal axis of the intake pipe 2121 at a first angular position and a second angular position. It should be understood that the first angular position is the first position, and the second angular position is the second position.

[0120] In some embodiments, the adjusting member 24 can also move back and forth around the longitudinal axis of the intake pipe 2121 at a third angular position and the second angular position. As the adjusting member 24 gradually rotates from the second angular position to the third angular position, the opening of the intake pipe 2121 gradually increases (i.e., the intake passage 42 gradually increases). As the adjusting member 24 gradually rotates from the third angular position to the second angular position, the opening of the intake pipe 2121 gradually decreases (i.e., the intake passage 42 gradually decreases).

[0121] Specifically, the adjusting member 24 includes a base 241 and a cylindrical sidewall 242. The base 241 is in the shape of a flat column with a longitudinally elongated quadrilateral cross-section, and the two short sides of the cross-section are arc-shaped, with the arc shape matching the wall shape of the second sidewall. The cylindrical sidewall 242 is erected on the upper end face of the base 241 and, together with the base 241, defines the liquid storage cavity 246.

[0122] In some embodiments, the diameter of the cylindrical sidewall 242 is adapted to the diameter of the first sidewall, and the two are interference-fitted to fix the adjusting member 24. The distance between the two ends of the cross-section of the base 241 is adapted to the diameter of the second sidewall.

[0123] like Figure 25 As shown, in some embodiments, the substrate 241 also has a control groove 2412 and at least one limiting groove 2411. The control groove 2412 is formed on the lower end surface of the substrate 241 and is used to control the rotation of the adjusting member 24. By rotating the adjusting member 24, the atomizer 1 is opened and closed. Specifically, the control groove 2412 is longitudinally elongated. There are four limiting grooves 2411, which are symmetrically formed in pairs on the sidewalls corresponding to the two long sides of the cross-section of the substrate 241. Each pair of limiting grooves 2411 is formed on the sidewalls corresponding to the ends of the two long sides of the cross-section of the substrate 241, and is used to cooperate with the limiting protrusion 2128 to play a limiting role.

[0124] In some embodiments, at least one air guide groove 2421 is also formed on the cylindrical sidewall 242 for cooperating with the air inlet groove 2126 to form an air inlet channel 42 with adjustable gas flow. Specifically, there are two air guide grooves 2421, which are symmetrically formed on the cylindrical sidewall 242 and correspond axially to the center points of the two long sides of the cross-section of the base 241.

[0125] It should be understood that the air intake channel 42 is connected to the atomizing chamber 216 via the air intake hole 2125, and the atomizing chamber 216 is connected to the air outlet channel 41. The three of them together define the air guide channel 40. Figure 29 The arrows in the diagram indicate the direction of gas flow.

[0126] In the specific implementation process, such as Figure 26 and Figure 27 As shown, at this time, the air guide groove 2421 and the air inlet groove 2126 are not in the corresponding positions. The air inlet channel 42 is sealed, and the atomizer 1 is in the closed state, which can prevent children from using it by mistake.

[0127] When atomizer 1 is needed, simply rotate the control slot 2412 to rotate the adjusting component 24, so that the two air guide slots 2421 gradually align with the two air inlet slots 2126. Figure 28 , Figure 29 As shown, the air intake channel 42 is open, and the atomizer 1 is in the open state. As the rotation amplitude increases, the area corresponding to the air guide groove 2421 and the air intake groove 2126 gradually increases, that is, the air intake channel 42 gradually increases, and the airflow increases.

[0128] The design of the regulating component 24 and the air intake pipe 2121 allows the atomizer 1 to be turned on and off at any time, preventing accidental use by children. The rotation amplitude of the regulating component 24 can be controlled by the control groove 2412, thereby controlling the proportion of the two air guide grooves 2421 relative to the two air intake grooves 2126, and thus controlling the size of the airflow channel, thereby achieving the purpose of controlling the airflow and realizing the user's customization of the atomized airflow.

[0129] Figures 30 to 37 The fourth embodiment of the present invention is shown. Its main difference from the third embodiment is that the structure of the atomizing component 23 and the structure of the upper seat 211 are the same as those in the second embodiment, and the accommodating portion 217, the first connecting portion 218 and the second connecting portion 219 are provided in the same way as in the second embodiment. These will not be described in detail here.

[0130] The present invention has at least the following beneficial effects:

[0131] 1. By setting an integrated atomizing base 21, the present invention reduces the number of parts of the atomizer 1, simplifies the structure, and greatly reduces assembly costs and material costs.

[0132] 2. By setting a movable adjustment component 24 and an air intake pipe 2121 that matches its structure, the airflow channel can be opened or closed, and the size of the airflow channel can be controlled to prevent children from using it and to allow users to customize the size of the atomized airflow.

[0133] 3. By providing a liquid storage chamber 246 inside the regulating component 24, the condensate generated during the atomization process can be collected, preventing the condensate from leaking out and damaging the atomizing device during use.

[0134] 4. By setting the adjustment component 24, the air intake channel 42 is kept in a closed state to prevent the atomizer 1 from leaking and damaging the atomizing device under conditions such as high temperature environment or long-term storage.

[0135] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
