[0042] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] Please also read Figures 1 to 4 An embodiment of the utility model provides an electronic atomization device, including a main unit 1 and a nozzle 2 connected to each other. In this embodiment, the main unit 1 and the nozzle 2 are preferably detachably connected to facilitate the user to replace the nozzle 2 or to perform maintenance or care on the inside of the main unit 1 by removing the nozzle 2.

[0044] The host 1 includes an atomizer 11 , and a mist outlet hole 1111 is provided on the atomizer 11 . The atomizer 11 is used to realize automatic atomization of the inhaled material, and the atomized inhaled material will be discharged into the suction nozzle 2 from the mist outlet hole 1111 .

[0045] The nozzle 2 includes a nozzle body 21 and a liquid absorbent member 22. A through suction channel 2121 is provided in the nozzle body 21. The first end of the suction channel 2121 close to the main unit 1 is used for the suction material discharged from the mist outlet 1111 to enter. The second end of the suction channel 2121 away from the first end (i.e., the end away from the main unit 1) is used for the suction material to be discharged outward and for the user to suck. The liquid absorbent member 22 is provided in the suction channel 2121, and the liquid absorbent member 22 extends along the length direction of the suction channel 2121 and At least part of the side wall of the suction channel 2121 is covered, thereby reducing the contact area between the suction nozzle body 21 and the suction object, thereby greatly reducing the possibility of the suction object forming condensate in the suction channel 2121. Even if a small amount of condensate is formed in the suction channel 2121, the liquid absorbent 22 can absorb the condensate remaining in the suction channel 2121, thereby solving the problem of suction leakage of the suction nozzle 2, thereby improving the user experience. The liquid absorbent 22 is preferably a sponge with better liquid absorption performance. In addition, a through hole 221 is provided on the liquid absorbent 22, and this through hole 221 is understood as at least a part of the suction channel 2121, so that the two ends of the suction channel 2121 are connected to provide the basic function of allowing the user to suck the preset suction object. The through hole 221 extends in a straight line, shortening the path of the suction object discharge, and reducing the amount of condensate formed by the suction object in the suction channel 2121 per unit time.

[0046] Please also read Figure 3 and Figure 4, the nozzle body 21 is provided with a groove 2122 recessed toward the second end at the first end of the suction channel 2121, and the liquid absorbent member 22 is inserted into the groove 2122 and covers at least part of the side wall of the groove 2122, thereby achieving the purpose of quickly installing the liquid absorbent member 22 on the nozzle body 21. More specifically, the nozzle body 21 can be designed to include a main body 211 and a central tube 212 protruding from the middle of the main body 211, and the main body 211 and the central tube 212 are preferably integrally injection molded, and the main body 211 is used to connect with the host 1. In this embodiment, the main body 211 and the host 1 are detachably connected, and the above-mentioned suction channel 2121 is provided in the central tube 212. In fact, the suction channel 2121 runs through the entire central tube 212, and the above-mentioned groove 2122 is provided at one end of the central tube 212 away from the main body 211. It can be seen that by setting the structural design of the main body 211 and the central tube 212, it is convenient to realize the connection between the suction nozzle 2 and the host 1, and it is also convenient to form the suction channel 2121 in the suction nozzle 2 and install the liquid absorbing member 22. In this embodiment, the suction nozzle 2 also includes an appearance member 23, which is sleeved on the outside of the suction nozzle body 21. The appearance member 23 can be connected to the suction nozzle body 21 separately, or the suction nozzle body 21 can be plastic-connected as a whole in the mold. The appearance member 23 is used to improve the overall aesthetics of the suction nozzle 2. Of course, the appearance member 23 needs to have a through hole 231 at the position facing the suction channel 2121, so that the suction object in the suction channel 2121 can pass through the hole 231 for the user to suck, thereby meeting the basic function of the suction nozzle 2.

[0047] Please refer to the Figure 3 and Figure 4 The host 1 also includes a liquid absorption block 12. When the nozzle 2 is connected to the host 1, the nozzle body 21 and the atomizer 11 clamp the liquid absorption block 12 together at the first end of the suction channel 2121 (i.e., the end of the central tube 212 away from the main body 211). The liquid absorption block 12 is used to absorb the leaked suction material or the condensed liquid flowing downward along the suction channel 2121. The liquid absorption block 12 is also preferably a sponge with better suction ability, thereby further reducing the probability of condensed liquid remaining in the suction channel 2121. In addition, a through middle hole 121 is provided on the liquid absorption block 12, and the middle hole 121 is connected to the mist outlet hole 1111 and the suction channel 2121 respectively, so that the mist suction material at the mist outlet hole 1111 can pass through the middle hole 121 and enter the suction channel 2121, thereby realizing the basic function that the atomized suction material can be sucked by the user.

[0048] See also Figure 1, this section specifically supplements the specific structure of the atomizer 11. In this embodiment, the atomizer 11 preferably includes a liquid storage tank 111, a liquid storage cotton 112 and a heating component 113, wherein a liquid storage chamber 1112 is provided in the liquid storage tank 111, and the outer wall of the liquid storage tank 111 is provided with the above-mentioned mist outlet hole 1111, and the mist outlet hole 1111 passes through the liquid storage chamber 1112. The liquid storage chamber 1112 is used to store liquid suction material, and the liquid storage cotton 112 is arranged in the liquid storage chamber 1112 and absorbs the liquid suction material, reducing the risk of the liquid suction material in the liquid storage chamber 1112 leaking out from the mist outlet hole 1111 in liquid form. The heating component 113 and the liquid storage cotton 112 are attached to each other. When the heating component 113 heats up, the liquid suction material in the liquid storage cotton 112 is atomized and discharged from the mist outlet hole 1111 to the suction channel 2121 of the suction nozzle 2.

[0049] Please also read Figure 2 and Figure 5 , a gas channel 14 is provided in the electronic atomization device, and the gas channel 14 is interconnected with the inside of the atomizer 11, and the gas channel 14 is connected to the outside, and the atomized liquid will enter the gas channel 14 and be discharged outward along the gas channel 14, so that the user can inhale the atomized preset liquid from the gas channel 14. It can be understood that the above-mentioned suction channel 2121 is a part of this gas channel 14. In addition, the gas channel 14 is provided with an air inlet 15 at one end away from the suction channel 2121, and the air inlet 15 is connected to the outside to balance the air pressure inside the gas channel 14 and the outside air, so that when the user inhales the gas channel 14, the mist liquid in the gas channel 14 can always be discharged smoothly to the outside, wherein Figures 2 to 3 The direction indicated by the thick arrow in the figure is the outlet direction of the gas channel 14. After the atomizer is used for a long time, condensate may accumulate at the air inlet 15. When the amount of condensate formed at the air inlet 15 is large, the condensate will accumulate and block the air inlet 15, thereby reducing the air intake area of ​​the air inlet 15, which in turn increases the resistance to the user's suction, and suction will become more and more difficult; moreover, the condensate accumulated at the air inlet 15 will form a thin film structure due to its own liquid tension. When the user inhales, the outside air will produce a gurgling sound when breaking through the thin film structure, which seriously reduces the user's experience. In this regard, the present solution provides the following two technical means to solve this technical problem:

[0050] The first technical means: a first absorbent cotton 13 is arranged in the gas channel 14 and adjacent to the air inlet 15. The first absorbent cotton 13 is used to absorb the condensed liquid accumulated at the air inlet 15, thereby solving the technical problem that the condensed liquid blocks the air inlet 15 and causes large suction resistance and gurgling sound. Optionally, the first absorbent cotton 13 is preferably arranged on one side of the air inlet 15 along the air outlet direction, so that when the user sucks the mist liquid in the gas channel 14, the outside air enters from the air inlet 15 and can drive the condensed liquid around the air inlet 15 to be absorbed by the first absorbent cotton 13 along the air outlet direction. In other embodiments, the first absorbent cotton 13 can also be arranged adjacent to the air inlet 15 in the non-air outlet direction. In this case, the electronic atomization device may need to be tilted or shaken to allow the condensed liquid accumulated at the air inlet 15 to be absorbed by the first absorbent cotton 13. Optionally, the first absorbent cotton 13 is further preferably an annular structure having a central hole 131 therein, and when the user sucks the mist liquid in the gas channel 14, the annular structure of the first absorbent cotton 13 can improve the efficiency of absorbing the condensed liquid accumulated at the air inlet 15, and also improve the reliability of eliminating the condensed liquid at the air inlet 15. The central hole 131 in the first absorbent cotton 13 is equivalent to a part of the above-mentioned gas channel 14.

[0051] The second technical means: at least one liquid guiding groove 17 is arranged in the gas channel 14, and a second liquid absorbent cotton 16 is arranged on the path where the liquid guiding groove 17 extends in the gas outlet direction of the gas channel 14. When the user sucks the mist liquid in the gas channel 14, the outside air enters from the air inlet 15 and can drive the condensed liquid around the air inlet 15 to flow along the liquid guiding groove 17. Since the second liquid absorbent cotton 16 is arranged on the path where the liquid guiding groove 17 extends in the gas outlet direction, the condensed liquid in the liquid guiding groove 17 is finally absorbed by the second liquid absorbent cotton 16, thereby solving the problem that the condensed liquid blocks the air inlet 15, causing large suction resistance and gurgling sound. Optionally, the gas channel 14 is preferably provided with a plurality of the above-mentioned liquid guide grooves 17, and the plurality of liquid guide grooves 17 are jointly arranged around the outer periphery of the air inlet 15, and the second liquid absorbent cotton 16 is simultaneously arranged on a path where the plurality of liquid guide grooves 17 extend in the air outlet direction. Through such a design, when the user sucks on the gas channel 14, the condensed liquid accumulated at the air inlet 15 can flow into the second liquid absorbent cotton 16 along the plurality of liquid guide grooves 17 respectively, thereby improving the efficiency of the second liquid absorbent cotton 16 in adsorbing the condensed liquid at the air inlet 15, and also improving the reliability of eliminating the condensed liquid at the air inlet 15.

[0052] It should be noted that the above two technical means can be used alone or in combination. In addition, the first liquid absorbent cotton 13 and the second liquid absorbent cotton 16 can be an integral structure or a split structure.

[0053] Please read again Figure 2 and Figure 5 The gas channel 14 specifically includes an air inlet 141, an air inlet cavity 142 and the above-mentioned suction channel 2121 which are connected in sequence. The air inlet hole 15 is provided at one end of the air inlet 141 away from the air inlet cavity 142. By designing the gas channel 14 in this way, the gas channel 14 can reserve a certain volume of gas in the air inlet cavity 142, so that the user can inhale enough mist-like preset liquid in one breath, thereby improving the user's experience. Based on the gas channel 14 of this structure, the above-mentioned first liquid absorbent cotton 13 is preferably arranged in the air inlet 141 and covers at least part of the inner wall of the air inlet 141, and the above-mentioned second liquid absorbent cotton 16 is arranged in the air inlet cavity 142. Optionally, the air inlet 141 and the suction channel 2121 are designed not to be on the same straight line, and the second absorbent cotton 16 is located on the extension path of the suction channel 2121, that is, when condensate is formed in the suction channel 2121 and falls in the direction of the air inlet cavity 142, the second absorbent cotton 16 can absorb the fallen condensate to prevent the condensate formed in the suction channel 2121 from directly falling into the air inlet 141 and causing blockage of the air inlet hole 15.

[0054] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
