Background

The electronic atomizing device mainly comprises an atomizer and a power supply device.

However, in the current atomizer, the fit gap between the atomizing shell and the heating seat is uniform, and the electronic atomizing device with a flat structure can easily deform the atomizing shell due to stress in the thickness direction. When the atomizer is assembled, because the sealing silica gel is in interference fit with the atomizing shell, the whole atomizer can be raised seriously in the thickness direction, and further the size of the atomizer in the thickness direction is larger, and the air tightness between the sealing silica gel and the atomizing shell is insufficient when the size of the atomizer is more serious, so that liquid leakage is caused.

As shown in fig. 2-5, the atomizer 100 according to some embodiments of the present invention may include an atomizing housing 10 and a heat generating component 30 housed in the atomizing housing 10. A liquid storage chamber 110 for storing liquid matrix and an air outlet channel 120 for outputting aerosol are formed in the atomizing shell 10, and an air outlet 121 communicated with the air outlet channel 120 and used for outputting aerosol is formed at one end of the atomizing shell 10. The heating assembly 30 includes a base 31, an atomizing core 35, and a heating seat 34, wherein the atomizing core 35 is accommodated in a space formed between the base 31 and the heating seat 34. The atomizing core 35 is in fluid communication with the reservoir 110 for adsorbing liquid matrix from the reservoir 110 and heating and atomizing the adsorbed liquid matrix to generate aerosol. In addition, the atomizing core 35 is also in air-guiding communication with the air outlet channel 120 to output the generated aerosol via the air outlet channel 120.

Specifically, the atomizing housing 10 may include a cylindrical housing 11 and an outlet pipe 12 disposed in the housing 11 in the longitudinal direction. The housing 11 may have a flat cylindrical shape, and may have a cross section of a narrow and long shape such as an elliptical shape, a racetrack shape, or a rectangular shape. An annular liquid storage cavity 110 is defined between the inner wall surface of the shell 11 and the outer wall surface of the air outlet pipe 12. The air outlet 121 is formed on the top wall of the housing 11, and the lower end (the end remote from the air outlet 121) of the housing 11 is an open end.

The air outlet pipe 12 is connected with the inner side of the top wall of the shell 11 and can be coaxially arranged with the shell 11, and an air outlet channel 120 is defined by the inner wall surface of the air outlet pipe 12. In this embodiment, the air outlet pipe 12 is integrally formed with the housing 11, for example, by injection molding. In other embodiments, the air outlet tube 12 and the housing 11 may be assembled after being molded separately.

The atomizing core 35 includes a liquid absorbing body 351 and a heating element 352 provided in the liquid absorbing body 351. The liquid absorbing body 351 is in liquid-conducting communication with the liquid storage chamber 110, and is used for absorbing liquid matrix from the liquid storage chamber 110 and conducting the liquid matrix to the heating body 352. The heating element 352 is electrically connected to the power supply device 200, and is configured to heat and atomize the liquid matrix adsorbed by the liquid absorbent 351 to generate aerosol after the power is applied.

The liquid absorbent 351 may be made of porous liquid absorbent ceramics, liquid absorbent cotton, or the like having a porous capillary structure. The liquid absorbent 351 has a liquid absorbent surface 3511 and a heat generating surface 3512. The heating surface 3512 is used for arranging a heating element 352, and the liquid absorbing surface 3511 is used for absorbing the liquid matrix from the liquid storage cavity 110 and conducting the liquid matrix to the heating surface 3512 through a porous capillary structure inside the liquid absorbing body 351. In this embodiment, the liquid absorbing body 351 is porous liquid absorbing ceramic, the liquid absorbing surface 3511 is located at a side of the liquid absorbing body 351 facing the liquid storage cavity 110, and the heat generating surface 3512 is located at a side of the liquid absorbing body 351 facing away from the liquid storage cavity 110. Specifically, the absorbent body 351 may include an absorbent body 3513 and two clip arms 3514 extending laterally outward from both sides of an upper end of the absorbent body 3513, respectively. Further, the two clip arms 3514 may be located at both sides of the liquid absorbing main body 3513 in the width direction. The upper surface of the absorbent 351 may be concave downward to form a recess 3510, such that the absorbent 351 is generally bowl-shaped. The inner wall surface of the recess 3510 defines a liquid suction surface 3511. The lower end surface of the liquid absorbent 351 forms a heating surface 3512, that is, a heating element 352 is disposed on an end surface of the liquid absorbent 351 facing the base 31.

The base 31 is embedded in the lower end of the housing 11 to cover the lower end opening of the housing 11. In addition, the base 31 is cooperatively connected with the heating seat 34 to fix the atomizing core 35. In the present embodiment, the base 31 and the heat generating seat 34 may be made of plastic, and the base 31 and the heat generating seat 34 are fastened together. An atomizing chamber 350 is formed between the base 31 and the heat generating surface 3512 of the atomizing core 35 for mixing the aerosol and air. The atomizing chamber 350 communicates with the outlet channel 120 to output a mixture of aerosol and air formed in the atomizing chamber 35 via the outlet channel 120. Further, an air inlet 314 may be formed on the base 31 to communicate with the atomizing chamber 350 so that external air can enter the atomizing chamber 350 through the air inlet 314.

As shown in fig. 2-6, in some embodiments, the base 31 may include a plate-shaped base 311, a cylindrical sidewall 312 extending upward from an upper end surface of the base 311, and two support arms 313 extending upward from both sides of the upper end of the cylindrical sidewall 312. Further, the two supporting arms 313 may be respectively formed by extending the upper end surfaces of the two sides of the cylindrical sidewall 312 along the width direction upwards along the longitudinal direction, and they may be respectively connected with the heating seat 34 in a snap connection manner. The cylindrical side wall 312 is fitted into the lower end opening of the housing 11, and the shape and size of the cross-sectional outer contour of the cylindrical side wall 312 are adapted to the shape and size of the cross-sectional inner contour of the lower end of the housing 11. The upper end surface of the base 311 may abut against the lower end surface of the housing 11, and the shape and size of the cross-sectional outer contour of the base 311 may be adapted to the shape and size of the cross-sectional outer contour of the lower end of the housing 11.

The upper end surface of the base 311 and the inner wall surface of the cylindrical sidewall 312 define a liquid storage space 3120, and the liquid storage space 3120 can store a certain amount of condensate, thereby reducing liquid leakage. The air inlet 314 longitudinally penetrates through the base 311 and can be positioned in the cylindrical side wall 312, and the central axis of the air inlet 314 can be coincident with the central axes of the base 311 and the cylindrical side wall 312. The upper end surface of the air intake hole 314 may be higher than the bottom surface of the liquid storage space 3120, so that the risk of leakage of liquid from the air intake hole 314 may be reduced.

Further, the heat generating component 30 may further include an electrode post 32 penetrating the base 31 in a longitudinal direction. The number of electrode columns 32 is usually two, and the two electrode columns 32 are electrically connected to the two poles of the heating element 352, respectively. The upper end face of the electrode column 32 is brought into contact with the heating element 352, so that the electrode column 32 can also function as a support for the atomizing core 35. Correspondingly, two electrode perforations 315 through which the two electrode columns 32 pass are also arranged on the base 311. In the present embodiment, the two electrode through holes 315 are located in the cylindrical sidewall 312, and may be respectively disposed on two sides of the base 311 along the width direction in a penetrating manner along the longitudinal direction. Further, the upper end surface of each electrode penetration hole 315 may be higher than the bottom surface of the liquid storage space 3120, so that the risk of leakage of liquid from the electrode penetration holes 315 may be reduced.

The atomizer 100 may also include a stationary cover 20 in some embodiments. The fixed cover 20 has a cylindrical shape with an open upper end, and may include a bottom wall 211 and a cylindrical sidewall 212 extending upward from an outer periphery of the bottom wall 211. The fixing cover 20 is sleeved outside the base 31 and the housing 11 to fix the base 31 in the housing 11. The fixing cover 20 can be made of metal, and the thermal expansion and cold contraction deformation generated when the temperature changes is small, so that the connection and fixation between the components in the atomizer 100 are more stable and reliable, and the sealing performance is better. In addition, when the atomizer 100 and the power supply device 200 are connected by magnetic attraction, the metal fixing cover 20 can also be used for magnetic attraction connection with the power supply device 200.

The fixing cover 20 may be snap-coupled with the housing 11, thereby achieving the fixation between the fixing cover 20 and the housing 11. In the present embodiment, two fastening portions 111 are formed on two outer wall surfaces of the lower end of the housing 11 along the width direction, two clamping grooves 2121 are formed on the cylindrical sidewall 212 of the fixed cover 20 corresponding to the two fastening portions 111, and the two fastening portions 111 can be fastened in the two clamping grooves 2121, so as to fasten the fixed cover 20 and the housing 11 together.

Further, in the present embodiment, there is a space between the lower end surface of the seat body 311 of the base 31 and the upper end surface of the bottom wall 211 of the fixed cover 20, which forms an air flow passage 310 communicating with the air intake hole 314. The lower end surface of the base 311 may further extend downward to form a plurality of positioning columns 316, and the plurality of positioning columns 316 may abut against the upper end surface of the bottom wall 211 to support and position the base 31.

Further, in some embodiments, the cylindrical sidewall 212 of the stationary cover 20 may also have an air inlet 2122 formed thereon that communicates with the air flow channel 310. In this embodiment, there are two air inlets 2122, and two air inlets 2122 are respectively formed by extending downward the lower end surfaces of two clamping grooves 2121. The base body 311 of the base 31 is formed with two notches 3111 corresponding to the two air inlets 2122, respectively, and specifically, the two notches 3111 may be formed by laterally inwardly recessed outer wall surfaces of both sides of the base body 311 in the width direction, respectively. The air inlet 2122, the notch 3111, the air flow passage 310, and the air inlet 314 are sequentially communicated to form an air inlet passage for introducing external air into the atomizing chamber 350.

In some embodiments, a vent hole 2111 communicating with the air flow passage 310 may also be formed in the bottom wall 211 of the stationary cover 20. In this embodiment, the central axis of the vent hole 2111 is offset from the central axis of the air intake hole 314. In other embodiments, the central axis of the vent 2111 may also coincide with the central axis of the inlet aperture 314. The vent 2111 may be used to communicate the airflow channel 310 with an airflow sensor in the power supply apparatus 200. Alternatively, the vent hole 2111 may be used as an air intake hole for introducing outside air into the airflow passage 310, and at this time, the vent hole 2111, the airflow passage 310, and the air intake hole 314 are sequentially communicated to form an air intake passage for introducing outside air into the atomizing chamber 350.

It will be appreciated that, in other embodiments, the lower end surface of the seat body 311 of the base 31 may also be in contact with the upper end surface of the bottom wall 211 of the fixed cover 20, i.e. the air flow channel 310 is not formed between the lower end surface of the base 31 and the upper end surface of the fixed cover 20. In other embodiments, the fixing cover 20 may not be provided, and the base 31 and the housing 11 may be fixed together by a snap connection, a screw connection, an interference fit connection, or the like.

Further, in some embodiments, the heat generating component 30 may further include a sealing member 33 sleeved on the base 31, a heat generating sleeve 37 sleeved on the heat generating seat 34, and a sealing pad 36 accommodated in the heat generating seat 34 and disposed between the heat generating seat 34 and the liquid absorbing body 351. The sealing member 33, the heating sleeve 37 and the sealing gasket 36 can be made of elastic materials such as silica gel.

The sealing member 33 may be sleeved on the cylindrical side wall 312 of the base 31, and an outer wall surface of the sealing member 33 may be in interference fit with an inner wall surface of the housing 11, so as to improve tightness. The sealing pad 36 can be annular, and the sealing pad 36 is tightly abutted between the heating seat 34 and the liquid absorbing body 351, so that the effects of buffering, ensuring the sealing performance, preventing liquid leakage and the like can be achieved. The heating sleeve 37 is sleeved on the upper part of the heating seat 34, and the outer wall surface of the heating sleeve 37 can be in interference fit with the inner wall surface of the shell 11 so as to improve the tightness. The heating sleeve 37 can be further provided with a through hole 370 along the longitudinal direction, the lower end of the air outlet pipe 12 can be embedded in the through hole 370, and the outer wall surface of the lower end of the air outlet pipe 12 is in sealing fit with the wall of the through hole 370.

As shown in fig. 2 to 5 and fig. 7 to 8, the heat generating seat 34 is accommodated in the housing 11 and is coaxially disposed with the housing 11. A first minimum fitting distance D1 is formed between the outer wall surface of the heat generating seat 34 and the inner wall surface of the housing 11 in the width direction of the atomizer 100. In the width direction of the atomizer 100, the outer wall surface of the heat generating seat 34 and the inner wall surface of the housing 11 may be in a clearance fit, a transition fit, or an interference fit. When the outer wall surface of the heat generating seat 34 and the inner wall surface of the housing 11 are fitted with a gap therebetween in the width direction, the first minimum fitting distance D1 is zero or more, for example, 0 to 0.1mm; at this time, the first minimum fitting distance D1 is the minimum fitting gap between the outer wall surfaces of the heat generating seat 34 on both sides in the width direction and the inner wall surfaces of the housing 11 on both sides in the width direction. When the outer wall surface of the heat generating seat 34 and the inner wall surface of the housing 11 are in interference fit (or interference fit) in the width direction, the first minimum fitting distance D1 is zero or less, for example, -0.15 to 0mm; at this time, the absolute value of the first minimum fitting distance D1 is the maximum interference between the outer wall surfaces of the heat generating seat 34 on both sides in the width direction and the inner wall surfaces of the housing 11 on both sides in the width direction. When the outer wall surface of the heat generating seat 34 and the inner wall surface of the housing 11 are in transition fit in the width direction, the first minimum fitting distance D1 may be greater than zero, equal to zero, or less than zero, for example, -0.08 to 0.08mm.

A second minimum fitting distance D2 is formed between the outer wall surface of the heat generating seat 34 and the inner wall surface of the housing 11 in the thickness direction of the atomizer 100. In the thickness direction of the atomizer 100, the outer wall surface of the heat generating seat 34 and the inner wall surface of the housing 11 may be in a clearance fit, a transition fit, or an interference fit. When the outer wall surface of the heat generating seat 34 and the inner wall surface of the housing 11 are in clearance fit in the thickness direction, the second minimum fitting distance D2 is zero or more, for example, 0 to 0.2mm; at this time, the second minimum fitting distance D2 is the minimum fitting gap between the outer wall surfaces of the heat generating seat 34 on both sides in the thickness direction and the inner wall surfaces of the housing 11 on both sides in the thickness direction. When the outer wall surface of the heat generating seat 34 and the inner wall surface of the housing 11 are interference fit (or interference fit) in the thickness direction, the second minimum fitting distance D2 is zero or less, for example, -0.1 to 0mm; at this time, the absolute value of the second minimum fitting distance D2 is the maximum interference between the outer wall surfaces of the heat generating seat 34 on both sides in the thickness direction and the inner wall surfaces of the housing 11 on both sides in the thickness direction. When the outer wall surface of the heat generating seat 34 and the inner wall surface of the housing 11 are in transition fit in the thickness direction, the second minimum fit distance D2 may be greater than zero, equal to zero, or less than zero, for example, -0.08 to 0.08mm.

Further, in the present embodiment, the first minimum mating distance D1 is smaller than the second minimum mating distance D2. Preferably, the outer wall surface of the heating seat 34 and the inner wall surface of the housing 11 are in transition fit or interference fit in the width direction, and the outer wall surface of the heating seat 34 and the inner wall surface of the housing 11 are in clearance fit in the thickness direction. In some embodiments, the first minimum mating distance D1 may be-0.08-0.1 mm and the second minimum mating distance D2 may be 0.08-0.2 mm. During assembly, the clearance between the outer wall surfaces of the heating seat 34 on both sides in the width direction and the inner wall surfaces of the housing 11 on both sides in the width direction is small or even interferes, so that the housing 11 can be restricted from being deformed to shrink inwards on both sides in the width direction to be small or to be enlarged due to interference fit. While the clearance between the outer wall surfaces of the heat generating seat 34 on both sides in the thickness direction and the inner wall surfaces of the housing 11 on both sides in the thickness direction is large, according to the principle that the circumference of the mating surface (inner wall surface) of the housing 11 is quantitative, when the housing 11 is deformed inward in the width direction, the bulge deformation of the housing 11 in the thickness direction is small, and even when the dimension of the housing 11 in the width direction is large due to interference fit, the dimension of the housing 11 in the thickness direction is thus small, so that the bulge deformation of the housing 11 in the thickness direction is small or does not bulge. Further, since the strength of the flat object in the thickness direction is weak at the time of assembly, the sealing performance in the thickness direction is weak, and the present embodiment can also improve the sealing performance between the outer wall surface of the heat generating seat 34 and the inner wall surface of the housing 11 by making the housing 11 less or not bulge out in the thickness direction.

The heat generating seat 34 may in some embodiments comprise a body portion 341 at a lower portion and a socket portion 342 at an upper portion. The cross-sectional shape of the socket 342 may be smaller than the cross-sectional shape of the body 341, and the heat generating jacket 37 may be sleeved on the socket 342. Further, the outer wall surfaces of the two sides of the body portion 341 along the width direction may be respectively formed with a limiting portion 3411 extending outwards, and a first minimum mating distance D1 is defined between the outer wall surface of the limiting portion 3411 and the inner wall surface of the housing 11. In the present embodiment, the stopper portion 3411 is located at the upper portion of the body portion 341 and is provided near the heat generating jacket 37, so that the sealing performance between the outer wall surface of the heat generating jacket 37 and the inner wall surface of the housing 11 can be improved.

At least one liquid inlet channel 340 for communicating the liquid suction body 351 with the liquid storage cavity 110 is further formed on the heating seat 34, and the liquid substrate in the liquid storage cavity 110 can supply liquid to the liquid suction surface 3511 of the liquid suction body 351 through the at least one liquid inlet channel 340. The top surface of the socket 342 is concavely formed with a vent hole 343 communicating with the lower end of the outlet channel 120. Specifically, in the present embodiment, the vent holes 343 are provided coaxially with the heat generation seat 34; two liquid inlet channels 340 are provided, and two liquid inlet channels 340 may be formed by extending the top surface of the sleeve portion 342 downward and may be located at two sides of the vent hole 343 along the width direction.

A receiving chamber 3410 for receiving the atomizing core 35 is formed in a concave shape on the bottom surface of the body 341. The two clamping arms 3514 of the atomizing core 35 can abut against the cavity wall of the receiving cavity 3410 to achieve the mounting positioning of the atomizing core 35 in the receiving cavity 3410. Other outer wall surfaces of the atomizing core 35 may not contact the cavity wall of the accommodating cavity 3410 to reduce the direct contact area between the atomizing core 35 and the heating seat 34, thereby reducing heat transfer from the atomizing core 35 to the heating seat 34 and reducing high-temperature deformation of the housing 11. Further, the two side walls of the accommodating cavity 3410 contacting the two clamping arms 3514 may be respectively recessed with a plurality of heat insulation grooves 3412, so as to further reduce the direct contact area between the atomizing core 35 and the heating seat 34.

In some embodiments, at least one vent 3415 communicating with the lower end of the vent 343 may be formed on the upper end sidewall of the body portion 341, and at least one air guide 3413 communicating the atomizing chamber 350 with the air outlet channel 120 may be formed on the lower end sidewall of the body portion 341. Specifically, in the present embodiment, there are two air ports 3415, and the two air ports 3415 are respectively provided on both sides of the upper end of the body portion 341 in the thickness direction; there are also two air guides 3413, and the two air guides 3413 are provided on both sides of the lower end of the main body 341 in the thickness direction.

Further, in some embodiments, at least one air guide channel 345 may be formed on the sidewall of the heat generating seat 34 to communicate the at least one air guide opening 3413 with the at least one air vent 3415. In the present embodiment, two air guide channels 345 are formed by the concave outer wall surfaces of the two sides of the heat generating seat 34 along the thickness direction, and the two air guide channels 345 may be rotationally symmetrical with respect to the central axis of the heat generating seat 34. The air guide channel 345 may be a fine groove structure and may have a certain extension length so that a certain leakage may be stored. Specifically, each air guide channel 345 may include a plurality of first air guide grooves 3451 extending in a transverse direction and a plurality of second air guide grooves 3452 extending in a longitudinal direction. One lateral end of the first air guide groove 3451 located at the lowermost position may communicate with the air guide port 3413. The lower end of the second air guide groove 3452 may communicate with one of the first air guide grooves 3451 located at the uppermost, and the upper end of the second air guide groove 3452 may communicate with the air vent 3415.

Further, in some embodiments, a plurality of openings 3414 may be formed on the sidewall of the heat generating base 34, so that a portion of the side surface of the liquid absorbent 351 is exposed. When the air flows through the openings 3414, part of heat of the atomizing core 35 can be taken away, so that the temperature of the atomizing core 35 can be reduced. In the present embodiment, the heat generating seat 34 is formed with a plurality of openings 3414 on both sides in the thickness direction. Specifically, two openings 3414 are provided on both sides of the heat generating seat 34 in the thickness direction, and the two openings 3414 are disposed above the air guide opening 3413 side by side in the lateral direction.

In addition, the first air guide groove 3451 and the second air guide groove 3452 may also be in communication with the plurality of openings 3414, so that the first air guide groove 3451 and the second air guide groove 3452 are in communication with the liquid absorbent 351. When the first air guide groove 3451 and the second air guide groove 3452 store the leaked liquid, the leaked liquid can be sucked to the liquid suction body 351 through the opening 3414, and the risk of the leaked liquid leaking into the power supply device 200 is reduced.
