[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Figures 1 to 6 An electronic atomizing device according to a first embodiment of the present invention is shown. This electronic atomizing device can be applied to the atomization of liquid media. The electronic atomizing device may include an atomizer and a power supply 81 mechanically and electrically connected to the atomizer. The atomizer is used to heat and atomize the liquid media, and the power supply 81 is used to supply power to the atomizer.

[0043] like Figures 1 to 6 As shown, the electronic atomizing device includes a housing 1, a base 2, an air duct 3, an atomizing assembly 4, a first sealing element 5, a nozzle 6, and a power supply 81. The base 2 is disposed within the housing 1 and located at one end of the housing 1. The air duct 3 is disposed within the housing 1, and one end 31 of the air duct 3 is mounted on the base 2. The first sealing element 5 is disposed within the housing 1 and is fitted onto the other end 32 of the air duct 3, with the first sealing element 5 spaced apart from the base 2. Thus, the outer wall surfaces of the first sealing element 5, the base 2, and the air duct 3, together with the inner wall surface of the housing 1, define a liquid storage chamber 7, which is used to store liquid media. The nozzle 6 is mounted at the end of the first sealing element 5 furthest from the liquid storage chamber 7.

[0044] The shell 1 is a longitudinally elongated flat cylinder. The shell 1 includes an open end 11 with an opening 111, a bottom end 12 opposite to the open end 11, and a side wall 13 connecting the open end 11 and the bottom end 12. The side wall 13 forms a receiving cavity 131 for the base 2, the vent pipe 3, the first sealing member 5 and other components to be housed therein.

[0045] It is understood that, in alternative embodiments, the liquid storage chamber 7 may be defined using a shell different from the housing 1. This shell may exist independently of the housing 1, such that the inner wall of the shell and the outer wall of the first seal 5, the base 2, and the vent pipe 3 define the liquid storage chamber 7, thereby forming an independent atomizer. This independent atomizer may be housed within the housing 1.

[0046] The base 2 is disposed in the housing 1. The base 2 may be in the form of a square frame structure. The base 2 includes a tube seat 21, a mounting seat 22 and a pair of connecting rods 23. The mounting seat 22 is located at the bottom end 12 of the housing 1. The tube seat 21 is disposed near the opening end 11. The pair of connecting rods 23 are disposed parallel and spaced apart between the tube seat 21 and the mounting seat 22, respectively connecting to the two opposite sides of the tube seat 21 and the two opposite sides of the mounting seat 22.

[0047] The tube seat 21, mounting base 22, a pair of connecting rods 23, and the inner wall of the side wall 13 of the housing 1 together define a power supply receiving cavity for the power supply 81 to be embedded therein. The tube seat 21 is adapted to the side wall 13, meaning the shape of the tube seat 21 matches the shape formed by the side wall 13, so as to facilitate the installation of the base 2 into the housing 1. Furthermore, a sealing arrangement is provided between the tube seat 21 and the side wall 13 to prevent leakage.

[0048] The vent pipe 3 includes one end 31 mounted on the pipe seat 21 and the other end 32 passing through the first sealing member 5. The vent pipe 3 from one end 31 to the other end 32 includes a first pipe section 33, a second pipe section 34, and a third pipe section 35 connected in sequence. The first pipe section 33 and the third pipe section 35 are both cylindrical, with the diameter of the first pipe section 33 being larger than that of the third pipe section 35. The diameter of the second pipe section 34 gradually increases from the third pipe section 35 to the first pipe section 33 and is arranged in a trumpet shape. The diameter of the first pipe section 33 is much smaller than the size of the pipe seat 21.

[0049] Combination Figure 10As shown, the portion of the first section 33 of the vent pipe 3 away from the second section 34 is mounted on the base 2. The portion of the first section 33 near the second section 34, the second section 34, and the third section 35 pass through the first sealing member 5. A gap exists between the pipe seat 21 and the first sealing member 5, thus the outer wall surface of the middle portion of the first section 33 and the inner wall surface of the side wall 13, and the first sealing member 5 and the pipe seat 21 respectively define the liquid storage chamber 7 radially and axially. A viewing window 14 is provided on the side wall 13 of the housing 1 corresponding to the liquid storage chamber 7 to observe the usage of the liquid medium.

[0050] The atomizing assembly 4 is disposed in the air duct 3 and can be electrically connected to the power supply 81. The atomizing assembly 4 may include an atomizing core 41 and a heating wire 42. The atomizing core 41 may be disposed in the first tube section 33, and the heating wire 42 may be disposed in the atomizing core 41 for heating the liquid medium within the atomizing core 41. The heating wire 42 can be connected to the power supply 81 via a lead wire 82.

[0051] The vent pipe 3 is provided with a liquid inlet hole 331. The liquid inlet hole 331 can be located in the middle part of the first pipe section 33 and penetrate through the side wall of the first pipe section 33, connecting the liquid storage chamber 7 and the atomizing core 41, so that the liquid medium in the liquid storage chamber 7 can enter the atomizing core 41.

[0052] The first sealing element 5 is sleeved on the vent pipe 3 to define and seal the liquid storage chamber 7. The first sealing element 5 may be made of silicone, providing good sealing performance. The first sealing element 5 includes an exhaust channel 52 and multiple liquid storage tanks 53. The exhaust channel 52 allows gas to escape between the liquid storage chamber 7 and the first sealing element 5 during the pressing and installation of the first sealing element 5 into the liquid storage chamber 7, preventing leakage due to gas compression of the liquid medium in the liquid storage chamber 7. The multiple liquid storage tanks 53 communicate with the liquid storage chamber 7, allowing liquid medium to enter when the first sealing element 5 comes into contact with the liquid medium in the liquid storage chamber 7, thereby preventing leakage due to compression and further preventing leakage.

[0053] Combination Figures 7 to 9 As shown, the first sealing member 5 is provided with a through hole 51 for the vent pipe 3 to pass through. The vent pipe 3 is tightly inserted into the through hole 51, that is, the vent pipe 3 and the first sealing member 5 are sealed together. The plurality of liquid storage tanks 53 are located on the periphery of the through hole 51. Specifically, the plurality of liquid storage tanks 53 are connected to the through hole 51 and are located on the inner wall surface of the through hole 51.

[0054] The plurality of liquid storage tanks 53 are arranged in a ring shape and axially distributed on the first sealing member 5. The liquid storage tanks 53 are spaced apart and parallel to each other, and adjacent liquid storage tanks 53 are connected by at least one connecting groove 54. Specifically, adjacent liquid storage tanks 53 can be connected by two connecting grooves 54, which can be located on opposite sides of the first sealing member 5, i.e., at a 180-degree angle on the first sealing member 5. It is understood that the plurality of liquid storage tanks 53 can be arranged approximately parallel, or adjacent liquid storage tanks 53 can be inclined at a certain angle, which also achieves the function of storing liquid media and is preferable.

[0055] In other embodiments, the liquid storage tank 53 may be arc-shaped and circumferentially formed on the inner wall surface of the through hole 51. Alternatively, the liquid storage tank 53 may be strip-shaped and extend in a direction parallel to the axial direction of the first seal 5, wherein the opening of the strip-shaped liquid storage tank 53 near the end of the liquid storage cavity 7 can allow the liquid medium to enter into the liquid storage tank 53 without the need for an additional liquid inlet 55.

[0056] In the axially adjacent connecting grooves 54, at least some of the adjacent connecting grooves 54 are staggered to lock in the liquid medium, thereby improving the liquid storage effect and ensuring the sealing effect between the first sealing element 5 and the vent pipe 3. The staggered connecting grooves 54 can be staggered at 90 degrees or other angles.

[0057] The first sealing element 5 further includes at least one liquid inlet 55, which is used to connect the liquid storage chamber 7 with the plurality of liquid storage tanks 53, allowing liquid medium to enter the plurality of liquid storage tanks 53 from the liquid inlet 55. The at least one liquid inlet 55 is located at one end of the plurality of liquid storage tanks 53 near the liquid storage chamber 7 and is in communication with the liquid storage tank 53 closest to the liquid storage chamber 7.

[0058] The at least one liquid inlet 55 may include two inlets, which may be located on opposite sides of the first seal 5, i.e., at a 180-degree angle on the first seal 5. In other embodiments, the two liquid inlets 55 may be located at other angles on the first seal 5.

[0059] The two liquid inlets 55 can be offset from the adjacent connecting groove 54 to lock in the liquid medium, resulting in better liquid storage and ensuring a good seal between the first sealing element 5 and the vent pipe 3. The liquid inlets 55 and the connecting groove 54 can be offset at 90 degrees or other angles.

[0060] like Figure 8 and Figure 9As shown, in this embodiment, the liquid inlet 55 and the connecting groove 54 can be arranged such that the connecting groove 54 closest to the liquid inlet 55 is offset from the liquid inlet 55, and the connecting groove 54 is offset from the connecting groove 54 adjacent to it in the axial direction. The other connecting grooves 54 are not offset. The offset arrangement means that they are located on the same axis as the first sealing member 5.

[0061] The first sealing element 5 is provided with two liquid inlets 55 and adjacent liquid storage tanks 53 are connected by two connecting grooves 54, so that the liquid medium in the liquid storage chamber 7 can enter the liquid storage tank 53 simultaneously through the two liquid inlets 55, and the liquid medium flows radially along the liquid storage tank 53 in two directions, and then enters the next liquid storage tank 53 through the connecting grooves 54, gradually filling each liquid storage tank 53. The symmetrical arrangement of the liquid inlets 55 and the connecting grooves 54 can speed up the liquid entry and filling efficiency.

[0062] In other embodiments, the same first seal 5 may have one, two, or other inlets 55, and adjacent liquid storage tanks 53 may be connected by one, two, or other connecting grooves 54. The number of inlets 55 may be the same as or different from the number of connecting grooves 54 connecting adjacent liquid storage tanks 53, and the number of connecting grooves 54 between each adjacent liquid storage tank 53 may be the same or different. Those skilled in the art can configure these settings according to actual needs. When there are three or more inlets 55 and connecting grooves 54, these three or more inlets 55 and connecting grooves 54 may be evenly arranged circumferentially on the first seal 5.

[0063] The plurality of liquid storage tanks 53 have capillary action and their widths are between 0.1 and 0.5 mm, thus serving to store liquid media. Specifically, the plurality of liquid storage tanks 53 can be formed by multiple fins, with adjacent fins forming one liquid storage tank 53. Liquid inlets 55 and connecting grooves 54 are respectively provided on the fins, and the liquid inlets 55 and connecting grooves 54 can be provided in the form of tanks, notches, openings, etc. Alternatively, the plurality of liquid storage tanks 53 can be formed by multiple inward recesses on the inner wall surface of the through hole 51, and the liquid inlets 55 and connecting grooves 54 can be formed by inward recesses on the inner wall surface of the through hole 51.

[0064] The portion of the first pipe segment 33 near the second pipe segment 34, the second pipe segment 34, and the third pipe segment 35 pass through the through hole 51 of the first sealing member 5. Correspondingly, the through hole 51 of the first sealing member 5 includes a first hole segment 511, a second hole segment 512, and a third hole segment 513, respectively corresponding to and adapted to the first pipe segment 33, the second pipe segment 34, and the third pipe segment 35. The plurality of liquid storage tanks 53 are disposed on the inner wall surfaces of the first hole segment 511 and the second hole segment 512. The liquid storage tanks 53 located in the first hole segment 511 have equal diameters. The liquid storage tanks 53 located in the second hole segment 512 have diameters that gradually increase from near the third hole segment 513 to near the first hole segment 511, and are arranged in a trumpet shape, adapting to the size of the second pipe segment 34. In other embodiments, a liquid storage tank 53 may also be disposed on the inner wall surface of the third hole segment 513, thereby providing more liquid storage space.

[0065] The venting channel 52 includes at least one venting groove 521, which communicates with the through hole 51 and is located at the end of the plurality of liquid storage tanks 53 away from the liquid storage cavity 7. Understandably, when the first sealing member 5 is sleeved onto the vent pipe 3 and pressed down into the liquid storage cavity 7, gas can enter the at least one venting groove 521 through the through hole 51, thereby preventing the gas from compressing the liquid medium in the liquid storage cavity 7; when the plurality of liquid storage tanks 53 store liquid medium, the liquid medium in the liquid storage tanks 53 serves to isolate the at least one venting groove 521 from the liquid storage cavity 7.

[0066] The at least one exhaust groove 521 may be located on the inner wall surface of the through hole 51, thereby accelerating the air intake speed. The at least one exhaust groove 521 may be elongated, with one end connected to a plurality of liquid storage tanks 53, and the other end penetrating the end face of the first sealing member 5 away from the liquid storage cavity 7, so that the gas in the liquid storage tank 53 can enter the exhaust groove 521.

[0067] The at least one venting groove 521 is connected to the liquid storage tank 53 furthest from the liquid storage cavity 7 among the plurality of liquid storage tanks 53. The at least one venting groove 521 and the liquid storage tank 53 can be connected through at least one through groove 56. The arrangement of the at least one through groove 56 can be the same as or different from the arrangement of the connecting groove 54. In this embodiment, the at least one through groove 56 may include two through grooves, which may be located at 180 degrees on the first sealing member 5, and the through groove 56 and the adjacent connecting groove 54 are located on the same axis of the first sealing member 5; or, the at least one venting groove 521 is directly connected to the liquid storage tank 53. The width of the at least one venting groove 521 is greater than or much greater than the width of the liquid storage tank 53. The width of the venting groove 521 is the radial dimension of the venting groove 521 in the first sealing member 5 to facilitate gas flow.

[0068] The at least one vent groove 521 may include two, and the two vent grooves 521 may be located approximately on two opposite sides of the first seal 5, that is, the two vent grooves 521 may be located approximately at a 180-degree position on the first seal 5.

[0069] In other embodiments, the two vent grooves 521 may be located at other angular positions on the first seal 5. These two vent grooves 521 are offset from the through groove 56 communicating with them, wherein the offset can be 60-120 degrees. In other embodiments, at least one vent groove 521 may include one or more other vent grooves; when at least one vent groove 521 includes multiple vent grooves, the multiple vent grooves 521 may be circumferentially and evenly arranged on the first seal 5.

[0070] The exhaust passage 52 also includes at least one air guide groove 522, which is in communication with at least one exhaust groove 521. The at least one air guide groove 522 is closer to the outer wall surface of the first seal 5 than the at least one exhaust groove 521, that is, the air guide groove 522 is closer to the outer wall surface of the first seal 5 in the radial direction of the first seal 5, so as to guide the gas to flow towards the outer wall surface of the first seal 5.

[0071] The gas guide groove 522 can be generally rectangular in shape and is located at the end of the first sealing member 5 away from the liquid storage tank 53. Specifically, one end of the gas guide groove 522 can be located between the two ends of the exhaust groove 521 along its axial length, and the other end of the gas guide groove 522 penetrates the end face of the first sealing member 5 away from the liquid storage chamber 7. The gas guide groove 522 can extend radially from the exhaust groove 521 and is located close to the outer wall surface of the first sealing member 5. Understandably, the size of the gas guide groove 522 is larger than or much larger than the size of the liquid storage tank 53 to facilitate gas flow.

[0072] The number of at least one air guide groove 522 may be the same as or different from the number of at least one exhaust groove 521. In this embodiment, the at least one air guide groove 522 may include two, and the two air guide grooves 522 are respectively connected to the two exhaust grooves 521 in a one-to-one correspondence. The air guide grooves 522 are located on the radial extension line of the exhaust grooves 521 they are connected to. That is, the two air guide grooves 522 may be located approximately on two opposite sides of the first sealing member 5, that is, the two air guide grooves 522 may be located approximately at a 180-degree position on the first sealing member 5.

[0073] The first sealing element 5 includes an axially arranged flat cylindrical main body 57 and a protrusion 58, which is closer to the liquid storage cavity 7 than the main body 57. The axial dimension of the main body 57 may be larger than the axial dimension of the protrusion 58. The protrusion 58 includes an axially arranged sealing portion 581 and a protrusion 582, which is closer to the liquid storage cavity 7 than the sealing portion 581. The sealing portion 581 is adapted to the side wall 13, that is, the shape of the sealing portion 581 is adapted to the shape of the corresponding position of the inner wall surface of the side wall 13, and the size of the sealing portion 581 is smaller than or slightly smaller than the inner diameter of the side wall 13.

[0074] The outer diameter of the protrusion 582 is smaller than the outer diameter of the sealing part 581. Specifically, the outer diameter of the protrusion 582 is slightly larger than the outer diameter of the first section 33 of the vent pipe 3, thereby facilitating the protrusion 582 to extend into the liquid medium in the liquid storage chamber 7. The side wall surface of the sealing part 581 is in sealed contact with the inner wall surface of the side wall 13, so that the end face of the sealing part 581 near the end of the protrusion 582 can together define the liquid storage chamber 7.

[0075] At least a plurality of liquid storage tanks 53 are disposed on the protrusion 58. Specifically, the first hole section 511 and the second hole section 512 are respectively located on the protrusion 582 and the sealing part 581, and the plurality of liquid storage tanks 53 are correspondingly distributed in the first hole section 511 and the second hole section 512. The third hole section 513 is located on the main body 57, and the exhaust groove 521 and the air guide groove 522 are located on the main body 57. The exhaust groove 521 communicates with the third hole section 513, and the air guide groove 522 communicates with the exhaust groove 521.

[0076] The housing 1 has an opening 111 at its open end 11 to facilitate the installation of various components. The suction nozzle 6 is installed at the opening 111 and mates with the first sealing member 5. The outer wall surface of the first sealing member 5 has an engaging portion 59, and the suction nozzle 6 has a fastening portion 61 for engaging with the engaging portion 59. Specifically, the radial dimension of the main body 57 is smaller than the radial dimension of the sealing portion 581, thereby forming an end face of the sealing portion 581 away from the liquid storage chamber 7. Hook portions 591 are provided on two opposite sides of the main body 57. The hook portions 591 are located at the end of the main body 57 near the suction nozzle 6, thereby forming an engaging portion 59 between the hook portions 591 and the end face of the sealing portion 581.

[0077] The mouthpiece 6 includes an abutment portion 62 located in the upper part of the mouthpiece 6, and an airflow channel 63 that is tightly connected to the air tube 3 inside the abutment portion 62. The lower part of the mouthpiece 6, that is, below the abutment portion 62, has a hollow structure, forming a mouthpiece opening 64 that can be fitted onto the main body 57. The mouthpiece opening 64 has two opposite sides with slots 65, and a fastening portion 61 is formed between the slots 65 and the end of the mouthpiece opening 64. The end of the mouthpiece 6 away from the first seal 5 has an air outlet 66 that communicates with the airflow channel 63 for the user to inhale.

[0078] Understandably, the nozzle 6 is fitted onto the first seal 5 through the nozzle opening 64, and the hook 591 is snapped into the slot 65, the fastening part 61 is snapped into the fastening part 59, the end face of the abutting part 62 abuts against the end face of the main body part 57 near the nozzle 6, and the airflow channel 63 is sealed and connected to the air pipe 3.

[0079] A gap exists between the contact portion 62 and the main body portion 57. To prevent gas from entering the airflow channel 63 via the exhaust groove 521, the vent pipe 3 and the suction nozzle 6 are sealed together by a second sealing member 9. Specifically, the second sealing member 9 includes a connecting portion 91 and a connecting hole 92 penetrating both ends of the connecting portion 91. The connecting portion 91 includes a sleeve portion 911 for fitting onto the vent pipe 3 and a plug portion 912 for plugging into the airflow channel 63. The sleeve portion 911 is cylindrical. The main body portion 57 is provided with a recessed groove 571 for installing the sleeve portion 911. This recessed groove 571 can be formed by a recess in the end face of the main body portion 57. The third section 35 of the vent pipe 3 is partially exposed and extends out of the recessed groove 571 so that the sleeve portion 911 can be fitted onto it. The connecting hole 92 communicates with the vent pipe 3 and the airflow channel 63. The second sealing member 9 can be made of silicone, which has good sealing properties.

[0080] The working principle of the first sealing element 5 of the present invention is as follows: Figure 2 As shown, before installation, that is, before the first sealing element 5 is sleeved onto the vent pipe 3 and pressed down into the liquid storage chamber 7 to contact the liquid medium, the gas can be discharged through the exhaust groove 521, the air guide groove 522 and then through the gap between the first sealing element 5 and the suction nozzle 6, and the gap between the suction nozzle 6 and the housing 1.

[0081] When the inlet 55 comes into contact with the liquid medium, the first seal 5 continues to be pressed down until it is fully installed. When fully installed, the protrusion 582 is partially or completely submerged in the liquid medium, and the sealing part 581 is positioned above the liquid surface. Figure 3 and Figure 4 As shown, the liquid medium enters the storage tank 53 through the inlet 55 and is stored in the storage tank 53. The through-slot 56 allows the gas in the storage tank 53 to be discharged through the exhaust slot 521. At this time, the liquid medium stored in the storage tank 53 acts as a seal for the storage cavity 7, thereby preventing outside air from entering the storage cavity 7 and affecting the gas pressure inside the storage cavity 7.

[0082] As suction proceeds, the liquid medium in the storage chamber 7 is continuously consumed. When the liquid level of the liquid medium is lower than the protrusion 582, due to the capillary force of the storage tank 53, the liquid medium in the storage tank 53 is still stored in the storage tank 53, which plays the role of sealing the storage chamber 7, thereby preventing outside air from entering the storage chamber 7, affecting the air pressure in the storage chamber 7, and causing leakage.

[0083] Figure 11 An electronic atomizing device according to a second embodiment of the present invention is shown. The difference between the electronic atomizing device of this embodiment and the electronic atomizing device of the first embodiment is that the structure of the first sealing member 5a in this embodiment is different from the structure of the first sealing member 5 in the first embodiment.

[0084] Combination Figure 12 and Figure 13 As shown, the first sealing element 5a includes a through hole 51a for the vent pipe 3 to pass through, and a plurality of liquid storage tanks 53a are located around the through hole 51a. Specifically, the plurality of liquid storage tanks 53a are disposed on the outer wall surface of the first sealing element 5a. The through hole 51a includes a first hole section 511a, a second hole section 512a, and a third hole section 513a corresponding to the first pipe section 33, the second pipe section 34, and the third pipe section 35, respectively.

[0085] The first sealing element 5a includes an axially arranged main body 57a and a protrusion 58a. The protrusion 58a is closer to the liquid storage cavity 7 than the main body 57a. The protrusion 58a is adapted to the side wall 13, that is, the shape of the protrusion 58a is the same as the shape of the corresponding position of the inner wall surface of the side wall 13, and the size of the protrusion 58a is smaller than or slightly smaller than the inner diameter of the side wall 13. The outer wall surface of the protrusion 58a is sealed to the inner wall surface of the side wall 13. A plurality of liquid storage tanks 53a are provided on the outer wall surface of the protrusion 58a.

[0086] Multiple liquid storage tanks 53a are axially spaced on the protrusion 58a and arranged in a ring. Adjacent liquid storage tanks 53a are connected by at least one connecting groove 54a, and the multiple liquid storage tanks 53a are connected to the liquid storage cavity 7 through at least one liquid inlet 55a. In this embodiment, adjacent liquid storage tanks 53a are connected by one connecting groove 54a, and the liquid storage tank 53a closest to the liquid storage cavity 7 is connected to the liquid storage cavity 7 through one liquid inlet 55a.

[0087] The connecting groove 54a adjacent to the liquid inlet 55a is offset from the liquid inlet 55a, and all adjacent connecting grooves 54a are also offset. The offset liquid inlet 55a and connecting groove 54a, and connecting grooves 54a and connecting grooves 54a can be located on opposite sides of the first sealing member 5a, that is, at a 180-degree position on the first sealing member 5a.

[0088] The first hole section 511a and the second hole section 512a are provided on the protrusion 58a, the plurality of liquid storage tanks 53a are provided corresponding to the first hole section 511a and the second hole section 512a, and the third hole section 513a is provided on the main body 57a.

[0089] The protrusion 58a includes a sealing portion 581a and a protrusion 582a of equal outer diameter. The protrusion 582a is closer to the liquid storage chamber 7 than the sealing portion 581a. The protrusion 582a is hollow, and its inner diameter is larger than the outer diameter of the vent pipe 3. Specifically, the hollow protrusion 582a forms a first hole section 511a. The inner diameter of the first hole section 511a is larger than the outer diameter of the first pipe section 33 of the vent pipe 3 and is close to the outer diameter of the first hole section 511a, so that the protrusion 582a can extend into the liquid medium. A second hole section 512a is located on the sealing portion 581a.

[0090] Because there is a gap between the outer wall surface of the main body 57a and the inner wall surface of the nozzle 6 and the housing 1, in this embodiment, the exhaust channel 52a is defined by the outer wall surface of the main body 57a and the inner wall surfaces of the nozzle 6 and the side wall 13. This exhaust channel 52a is located at the end of the plurality of liquid storage tanks 53a furthest from the liquid storage chamber 7. Among the plurality of liquid storage tanks 53a, the liquid storage tank 53a closest to the exhaust channel 52a is connected to the exhaust channel 52a through a through groove 56a. It can be understood that in this embodiment, the first sealing member 5a does not need to be provided with an exhaust groove and a guide groove; the nozzle 6 and the vent pipe 3 are directly and sealed together, and a second sealing member is not required.

[0091] The shell, air tube, and nozzle of this embodiment have the same structure as those of the shell, air tube, and nozzle of the first embodiment. Other components and component features of this embodiment are the same as or substantially the same as the corresponding components and component features of the first embodiment. The components and component features of the two embodiments can be freely combined without contradiction.

[0092] 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.
