The atomizer 20 is used for receiving a liquid medium, heating and atomizing the liquid medium, and transporting mist. In some embodiments, the battery device 10 has a receiving slot 11 formed at the top thereof, and the atomizer 20 is detachably inserted into the receiving slot 11 and electrically connected to the battery device 10.

Referring to fig. 3-5 together, the atomizer 20 may in some embodiments include a generally square reservoir 21 and an atomizing assembly 22 detachably mounted in the reservoir 11, the reservoir 21 being mainly used for storing liquid medium and delivering mist, and the atomizing assembly 22 being mainly used for heating and atomizing the liquid medium from the reservoir 21. Atomizing assembly 22 may be inserted into reservoir assembly 21 in an interference fit (i.e., a tight expansion fit) in some embodiments, so that atomizing assembly 22 can be easily removed and installed. This is particularly true where atomization assembly 22 cannot be cylindrically configured.

The atomizer 20 may also include an injection device 23 and a nozzle assembly 24 in some embodiments. The liquid injection device 23 is embedded on the top of the liquid storage component 21 and is communicated with the liquid storage cavity 210 so as to conveniently inject liquid into the liquid storage cavity 210.

The reservoir 210 is used for storing a liquid medium, and the receiving cavity 211 may have a cylindrical shape in some embodiments, so that the atomizing assembly 22 is detachably inserted therein. The receiving cavity 211 extends vertically upward from the bottom surface of the liquid storage assembly 21 to the liquid storage cavity 210, and the receiving cavity 211 is communicated with the liquid storage cavity 210 through a plurality of first liquid inlets 2110. The air inlet passage 212 extends from the air inlet 2121 to the lower portion of the reservoir assembly 21, and communicates with the lower portion of the receiving cavity 211 at the air outlet 2122, so that the external air enters the reservoir assembly 21 from the upper portion, then flows downward, and enters the atomizing assembly 22 from the lower portion of the receiving cavity 211.

The fastening bracket 2213 is used for holding the atomizing core assembly 222 and electrically connecting the atomizing core assembly 222 with the base 2211. In some embodiments, a sealing ring 2214 is disposed between the base 2211 and the conductive post 2212 to achieve an insulating connection, and the elastic property of the sealing ring 2214 allows the conductive post 2212 to have a certain axial displacement after receiving an external force, so as to facilitate the installation of the atomizing core assembly 222.

The base 2211 may be in the shape of a disk in some embodiments, and has a central through hole 2211a for the sealing ring 2214 to pass through, a cutout 2211b formed on the periphery of the outer wall surface near the bottom surface, and a receiving groove 2211c formed on the periphery of the outer wall surface near the top surface. The cutout 2211b is used for a user to serve as a force application position, so that the atomizing component 22 can be conveniently pulled out of the liquid storage component 21 to form a handle position at the tail end of the atomizing component 22. Correspondingly, an opening of the accommodating cavity 211 of the liquid storage assembly 21 is provided with a receding portion 2113, so that the matting 2211b is exposed, and the operation of a user is facilitated. The accommodating groove 2211c is used for accommodating the third sealing member 2215, and the third sealing member 2215 increases the expansion fitting force between the side wall surface of the atomizing assembly 22 and the inner wall surface of the accommodating cavity 211 on one hand, and prevents liquid leakage through the gap between the side wall surface of the atomizing assembly 22 and the inner wall surface of the accommodating cavity 211 on the other hand. In this way, the atomization assembly 22 and the liquid storage assembly 21 are matched together through three sealing members which are distributed at intervals, and the stability is very good.

The top end of the cylindrical conductive part 2212b has a head part with a larger diameter, and the upper side edge of the head part is further provided with a first guide part 2212d in an inverted angle shape to facilitate mounting of the atomizing core assembly 222 to the base 221.

The fastening bracket 2213 may be C-shaped in some embodiments with an opening in one side for the atomizing core assembly 222 to fit in from one side. The fastening bracket 2213 may include a C-shaped connecting wall 2213a connected to the base 2211, a C-shaped fixing wall 2213b connected to the upper side of the connecting wall 2213a, and a flat C-shaped blocking wall 2213C connected to the upper side of the C-shaped fixing wall 2213b and turned inwards horizontally. A plurality of air passing holes 2213d may be formed in the connecting wall 2213a to facilitate smooth air flow. The blocking wall 2213c is used for positioning the atomizing core assembly 222 in the axial direction, and the lower surface of the end portion thereof near the opening of the fastening support 2213 may be further provided with a second guide portion 2213e for facilitating the lateral clamping of the atomizing core assembly 222 into the fastening support 2213.

As shown in fig. 8 and 9, the atomizing core assembly 222 may include, in some embodiments, a fixing tube 2221 capable of conducting electricity, a tubular liquid absorbing member 2222 disposed in the fixing tube 2221, a heat generating member 2223 disposed in a central through hole of the liquid absorbing member 2222, a liquid locking member 2224 wrapped around the fixing tube 2221 and connected to the liquid absorbing member 2222 in a liquid guiding manner, a tubular conductive shell 2225 wrapped around the liquid locking member 2224 and electrically connected to the fixing tube 2221, a sealing ring 2226 mounted at a lower end of the fixing tube 2221, and a conductive tube 2227 inserted into the sealing ring 2226. The central through hole of liquid absorbing member 2222 defines an atomizing chamber 2222a, and conductive cylinder 2227 is in communication with the central through hole of liquid absorbing member 2222. The outer edge of the lower end of the conductive cylinder 2227 is formed with a third guide portion 2227a to cooperate with the first guide portion 2212d of the conductive post 2212 to facilitate the installation of the atomizing core assembly 222. Tubular liquid absorbing member 2222 may be wound of liquid absorbing cotton in some embodiments, heat generating member 2223 may be a heating wire or a heating net, etc., and tubular liquid absorbing member 2222 and heat generating member 2223 together form the atomizing core of atomizing core assembly 222.

The heat generating member 2223 includes two terminals electrically connected to the fixed barrel 2221 and the conductive barrel 2227, respectively. The fixed cylinder 2221 and the conductive cylinder 2227 are electrically connected to the base 2211 and the conductive post 212, respectively, and further electrically connected to the positive and negative electrodes of the battery device 20, respectively. Herein, the fixed cylinder 2221 and the conductive cylinder 2227 constitute the third electrode connection and the fourth electrode connection of the atomizing assembly 22. Liquid locking member 2224 is intended to prevent insufficient atomization due to excessive flow of liquid medium to liquid absorbing member 2222.

Stationary cartridge 2221, in some embodiments, includes an inlet port 2221a for fluidly connecting fluid lock 2224 to fluid suction member 2222. Conductive shell 2225 may include, in some embodiments, an annular flange 2225a and a number of inlet ports 2225 b. A flange 2225a is formed on the circumference of the outer surface of the conductive shell 2225 near the lower end thereof to abut against the lower side of the blocking wall 2213c of the fastening holder 2213, enabling the positioning of the atomizing core assembly 222 in the longitudinal direction. The inlet port 2225b communicates the locking member 2224 with the reservoir chamber 210.

However, when lateral pressure is applied, the conductive cylinder 2227 and the conductive post 2212 are slightly elastically deformed in the direction away from each other in the soft sealing ring, so that the lower end of the atomizing core assembly 222 can be completely pushed into the fastening holder 2213, at this time, the conductive cylinder 2227 and the conductive post 2212 are opposite to each other, and the flange 2225a of the conductive shell 2225 is tightly abutted by the blocking wall 2213c of the fastening holder 2213. And atomization assembly 22 is assembled. When atomizing assembly 22 needs to be disassembled, a laterally outward force is applied to overcome the friction between atomizing core assembly 222 and base 221.

As further shown in FIG. 6, when it is desired to assemble the atomizing assembly 22 to the reservoir assembly 21, the atomizing assembly 22 can be forcibly inserted into the receiving cavity 211 of the reservoir assembly 21. At this time, the first sealing member 2111 and the second sealing member 2112 are respectively expanded and fitted on the outer wall surface of the conductive shell 2225 of the atomizing core assembly 222d, and are located at the upper side and the lower side of the liquid inlet 2225b of the conductive shell 2225, so that the liquid storage cavity 210 of the liquid storage assembly 21 is in liquid-conducting connection with the liquid inlet 2225b of the atomizing core assembly 222. The third sealing element 2215 is tightly fitted on the sidewall of the receiving cavity 211 close to the bottom opening and is located below the air outlet of the air inlet channel 212, so that the air inlet channel 212 of the liquid storage assembly 21 is in air-guiding connection with the air inlet hole 2212c of the conductive post 2212. The air outlet of the atomizing cavity of the atomizing core assembly 222d is connected with the air inlet of the air outlet channel 213 of the liquid storage assembly 21, so as to form a complete atomizer 20 (the arrows in the figure 6 show the air flow direction). In some embodiments, it is also an advantage of the present design that the bottom surface of the atomizing assembly 22 and the bottom surface of the reservoir assembly 21 are preferably flush after the atomizing assembly 22 is assembled to the reservoir assembly 21.

It is understood that the above examples only represent preferred embodiments of the present invention, which are described in more detail and detail, but are not to be construed as limiting the scope of the present invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
