Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, specifically to an atomizing core assembly and an electronic atomization device. Background Technology

[0002] Liquid-core separation e-vaporizers utilize a mechanical structure design to isolate the atomizing matrix from the atomizing core when not in use. This technology aims to solve problems that may occur in traditional e-vaporizers during transportation, storage, or idle periods, such as oil leakage, excessive immersion of the atomizing core (core flooding), and deterioration of the atomizing matrix. In existing technologies, the atomizing core assembly typically includes a liquid-guiding cotton. During use, the oil passage between the liquid reservoir and the atomizing core assembly is opened, allowing the atomizing matrix to flow from the liquid reservoir to the atomizing core assembly for atomization. The atomization temperature and liquid conduction efficiency of the atomizing matrix during atomization both affect the taste of the subsequent aerosol.

[0003] Since the reservoir and oil passage are relatively sealed structures, during the process of the reservoir supplying the atomizing matrix to the atomizing core assembly and the atomizing core assembly consuming the atomizing matrix, the air pressure in the reservoir and oil passage gradually decreases. This causes the external air pressure to be greater than the air pressure in the reservoir and oil passage. External air will enter the reservoir and oil passage through the porous gaps of the liquid-guiding cotton to balance the air pressure. This results in the liquid-guiding cotton occupying some of the gaps, leading to insufficient or uneven liquid delivery. Consequently, the liquid-guiding cotton conducts liquid more slowly, affecting the taste of the aerosol. Utility Model Content

[0004] This utility model provides an atomizing core assembly and an electronic atomizing device. The atomizing core assembly can realize the exchange of air between the liquid storage chamber and the outside through the air exchange channel, avoiding excessive air occupation of the gap of the liquid guiding cotton, so that the liquid guiding cotton can guide the liquid fully and evenly, and improve the taste of aerosol.

[0005] The first aspect of this application provides an atomizing core assembly, comprising: an atomizing tube having a liquid inlet on its side wall; a liquid control tube disposed inside the atomizing tube, having a liquid guide port on its side wall, the liquid guide port communicating with the liquid inlet; a liquid guide element disposed inside the liquid control tube, at least a portion of the liquid guide port not covered by the liquid guide element; an atomizing air passage defined within the liquid control tube; the liquid inlet, the liquid guide port, the side wall of the atomizing tube, and the liquid guide element defining a ventilation channel; one end of the ventilation channel communicating with a liquid storage chamber, and the other end communicating with the atomizing air passage; and an atomizing core disposed within the liquid guide element for atomizing the atomizing matrix conducted by the liquid guide element.

[0009] In one embodiment, there are multiple liquid inlets, which are arranged at intervals around the side wall of the atomizing tube; there are also multiple liquid guide ports, which are arranged at intervals around the side wall of the control tube, and each liquid guide port corresponds to one of the liquid inlets.

[0010] In one embodiment, the side wall of the atomizing tube is provided with a first positioning structure, and the side wall of the liquid control tube is provided with a second positioning structure. The second positioning structure is used to cooperate with the first positioning structure so that the liquid guide port and the liquid inlet are aligned.

[0011] In one embodiment, the liquid guide port is elongated and extends along the length of the liquid control tube.

[0012] In one embodiment, the atomizing core includes an atomizing support, an inner casing, a fiberglass tube, and a heating element. The heating element is disposed on the atomizing surface of the inner casing. The inner casing and the fiberglass tube are disposed within the atomizing support, and the inner casing is connected to the fiberglass tube along the length of the atomizing support to form an atomizing airway. The atomizing support is disposed within a liquid guiding component.

[0013] The second aspect of this application provides an electronic atomizing device, including an atomizing chamber, a liquid storage chamber, and an atomizing core assembly protected by the first aspect.

[0014] In one embodiment, the system further includes a liquid inlet switch assembly. The liquid storage chamber has a liquid outlet for connecting the liquid storage chamber and the atomizing chamber. The liquid inlet switch assembly is disposed at the liquid outlet and can close or open the liquid outlet.

[0015] This application provides an atomizing core assembly and an electronic atomizing device.

[0025] Example 1

[0026] This embodiment provides an atomizing core assembly 100. Please refer to [reference needed]. Figure 1-3 The atomizing core assembly 100 includes an atomizing tube 110, a liquid control tube 120, a liquid guide 130, and an atomizing core 140.

[0027] Please refer to Figure 2-3 The atomizing tube 110 has a liquid inlet 111 on its side wall. A control tube 120 is located inside the atomizing tube 110, and a guide port 121 is located on its side wall, communicating with the liquid inlet 111. A guide component 130 is located inside the control tube 120, with at least a portion of the guide port 121 not covered by the guide component 130. An atomizing air passage 131 is defined within the control tube 120. The liquid inlet 111, guide port 121, side wall of the atomizing tube 110, and guide component 130 define a ventilation passage 150, one end of which communicates with the liquid storage chamber 211, and the other end with the atomizing air passage 131. An atomizing core 140 is located within the guide component 130 and is used to atomize the atomizing matrix conducted by the guide component 130.

[0028] In this application, a control pipe 120 is provided between the atomizing tube 110 and the liquid guiding component 130, and the liquid guiding port 121 on the control pipe 120 is connected to the liquid inlet 111 on the atomizing tube 110. The liquid guiding port 121 is at least partially not covered by the liquid guiding component 130. The control pipe 120 defines an atomizing air passage 131. The liquid inlet 111, the liquid guiding port 121, the atomizing tube 110, and the liquid guiding component 130 define a ventilation passage 150. One end of the ventilation passage 150 is connected to the atomizing tube 110. The air passage 131 is connected at one end and at the other end to the liquid storage chamber 211 of the electronic atomizing device 200. When the atomizing core assembly 100 is placed in the electronic atomizing device 200, outside air can enter the ventilation channel 150 from the atomizing air passage 131 and then enter the liquid storage chamber 211 from the ventilation channel 150. This minimizes the gap occupied by air in the liquid guiding component 130, making the liquid guiding component 130 more uniform and sufficient, accelerating the liquid guiding speed of the liquid guiding component 130, and improving the taste of the aerosol. In addition, a liquid control tube 120 is added to the inside of the atomizing tube 110, which can slow down the speed at which the atomizing matrix enters the liquid guiding component 130 and the atomizing core 140 to a certain extent, avoiding the problem of atomizing matrix leakage due to excessive atomizing matrix on the atomizing core assembly 100 and the air pressure inside the atomizing chamber 221 being lower than the outside atmospheric pressure.

[0029] Please refer to Figure 2-3 The area of ​​the liquid guide port 121 not covered by the liquid guide component 130 is located near the air outlet end of the atomizing tube 110.

[0030] By placing the portion of the liquid guide port 121 exposed on the liquid guide component 130 near the air outlet of the atomizing tube 110, outside air can enter the ventilation channel 150 in a timely manner to balance the air pressure between the liquid storage chamber 211 and the atomizing core assembly 100 and the outside.

[0031] In this embodiment, the length of the liquid guide port 121 protruding from the liquid guide member 130 along the length direction of the liquid control tube 120 is greater than 1 mm.

[0032] Please refer to Figure 1 The liquid guide port 121 is aligned with the liquid inlet port 111.

[0033] Aligning the liquid guide port 121 with the liquid inlet 111 facilitates the rapid entry of the atomized matrix into the liquid guide component 130, and also allows outside air to flow directly from the liquid guide port 121 through the liquid inlet 111.

[0034] Please refer to Figure 3 In the length direction of the liquid control tube 120, the length of the liquid guide port 121 is greater than the length of the liquid inlet port 111, and the liquid guide component 130 covers the position where the liquid guide port 121 and the liquid inlet port 111 are aligned.

[0035] Setting the length of the inlet 111 to be too large or too small is not conducive to the entry of the atomizing substrate. Since the guide port 121 needs to allow the atomizing substrate to pass through while also forming a ventilation channel 150 that connects with the atomizing air channel 131, the length of the guide port 121 needs to be larger than that of the inlet 111. The guide component 130 covers the position where the guide port 121 and the inlet 111 are aligned, which helps the atomizing substrate entering the guide port 121 to be directly adsorbed onto the guide component 130.

[0036] Please refer to Figure 3 The liquid inlet 111 includes multiple inlets, which are spaced apart around the side wall of the atomizing tube 110. The liquid guide port 121 includes multiple inlets, which are spaced apart around the side wall of the liquid control tube 120, and the liquid guide port 121 corresponds to the liquid inlet 111 one by one.

[0037] Multiple liquid inlets 111 and liquid guides 121 are provided at the same time, so that air can enter the liquid inlets 111 from all sides of the liquid control tube 120, which helps to make the atomized matrix on the liquid guide 130 more evenly distributed and further improves the taste of the aerosol.

[0038] Please refer to Figure 1 The atomizing tube 110 has a first positioning structure 112 on its side wall, and the liquid control tube 120 has a second positioning structure 122 on its side wall. The second positioning structure 122 cooperates with the first positioning structure 112 to align the liquid guide port 121 with the liquid inlet 111. In this embodiment, both the first positioning structure 112 and the second positioning structure 122 are grooves, and the grooves are aligned when the liquid control tube 120 is inserted into the atomizing tube 110. In other embodiments, the first positioning structure 112 can be either a protrusion or a groove, while the second positioning structure 122 has a different design; or, the first positioning structure 112 can be either a snap-fit ​​or a slot, while the second positioning structure 122 has a different design.

[0039] The design of the first positioning structure 112 and the second positioning structure 122 allows for convenient and quick alignment of the liquid guide port 121 with the liquid inlet port 111 for installation.

[0040] Please refer to Figure 3 The liquid guide port 121 is elongated and extends along the length of the liquid control tube 120.

[0041] The elongated liquid guide port 121 helps to form the air exchange channel 150 and shortens the air path of the air exchange channel 150, making it convenient to balance the air pressure of the electronic atomizing device 200 and the outside air pressure in a timely manner.

[0042] Please refer to Figure 3The liquid guide port 121 includes a square structure 123 and two semi-circular arc structures 124. The two ends of the square structure 123 are open, and one side of the semi-circular arc structure 124 is open. The open ends of the two semi-circular arc structures 124 are respectively connected to the two openings at the two ends of the square structure 123.

[0043] Please refer to Figure 2-3 The atomizing core 140 includes an atomizing support 141, an inner casing 142, a fiberglass tube 143, and a heating element 144. The heating element 144 is disposed on the atomizing surface of the inner casing 142. The inner casing 142 and the fiberglass tube 143 are disposed within the atomizing support 141, and the inner casing 142 is connected to the fiberglass tube 143 along the length of the atomizing support 141 to form an atomizing airway 131. The atomizing support 141 is disposed within the liquid guiding component 130. The inner casing 142 is inner cotton. More specifically, the atomizing support 141 has a tubular structure, and the surface of the atomizing support 141 also has a liquid inlet opening, through which the atomizing matrix enters the inner cotton. Furthermore, the atomizing airway 131 formed by the inner casing 142 and the fiberglass tube 143 is a part of the entire atomizing airway 131.

[0044] Since the liquid guiding component 130 is made of porous liquid guiding cotton material, when the heating element 144 heats the atomizing matrix to generate aerosol, the aerosol will enter the liquid guiding cotton, reducing the amount of aerosol being absorbed. The glass fiber tube 143 can form an atomizing air channel 131 in the liquid guiding cotton, which can minimize the amount of aerosol entering the liquid guiding cotton.

[0045] Please refer to Figure 2-3 The atomizing core assembly 100 also includes a base 160, with an atomizing tube 110, a liquid control tube 120, and a liquid guide 130 disposed on the base 160. The base 160 is disposed at the bottom of the atomizing chamber 221 to support the atomizing core assembly 100.

[0046] Please refer to Figure 2-3 The atomizing core assembly 100 also includes a support 170, on which the pins of the heating element 144 are mounted. The support 170 is used to mount the base 160 and to fix the atomizing core assembly 100 in the atomizing chamber 221.

[0047] Example 2

[0048] This embodiment provides an atomizing core assembly 100. Please refer to [reference needed]. Figure 1-3 The atomizing core assembly 100 includes an atomizing tube 110, a liquid control tube 120, a liquid guide 130, and an atomizing core 140.

[0049] Please refer to Figure 2-3The atomizing tube 110 has a liquid inlet 111 on its side wall. A control tube 120 is located inside the atomizing tube 110, and a guide port 121 is located on its side wall, communicating with the liquid inlet 111. A guide component 130 is located inside the control tube 120, with at least a portion of the guide port 121 not covered by the guide component 130. An atomizing air passage 131 is defined within the control tube 120. The liquid inlet 111, guide port 121, side wall of the atomizing tube 110, and guide component 130 define a ventilation passage 150, one end of which communicates with the liquid storage chamber 211, and the other end with the atomizing air passage 131. An atomizing core 140 is located within the guide component 130 and is used to atomize the atomizing matrix conducted by the guide component 130.

[0050] In this application, a control pipe 120 is provided between the atomizing tube 110 and the liquid guiding component 130, and the liquid guiding port 121 on the control pipe 120 is connected to the liquid inlet 111 on the atomizing tube 110. The liquid guiding port 121 is at least partially not covered by the liquid guiding component 130. The control pipe 120 defines an atomizing air passage 131. The liquid inlet 111, the liquid guiding port 121, the atomizing tube 110, and the liquid guiding component 130 define a ventilation passage 150. One end of the ventilation passage 150 is connected to the atomizing tube 110. The air passage 131 is connected at one end and at the other end to the liquid storage chamber 211 of the electronic atomizing device 200. When the atomizing core assembly 100 is placed in the electronic atomizing device 200, outside air can enter the ventilation channel 150 from the atomizing air passage 131 and then enter the liquid storage chamber 211 from the ventilation channel 150. This minimizes the gap occupied by air in the liquid guiding component 130, making the liquid guiding component 130 more uniform and sufficient, accelerating the liquid guiding speed of the liquid guiding component 130, and improving the taste of the aerosol. In addition, a liquid control tube 120 is added to the inside of the atomizing tube 110, which can slow down the speed at which the atomizing matrix enters the liquid guiding component 130 and the atomizing core 140 to a certain extent, avoiding the problem of atomizing matrix leakage due to excessive atomizing matrix on the atomizing core assembly 100 and the air pressure inside the atomizing chamber 221 being lower than the outside atmospheric pressure.

[0051] Please refer to Figure 2-3 The area of ​​the liquid guide port 121 not covered by the liquid guide component 130 is located near the air outlet end of the atomizing tube 110.

[0052] By placing the portion of the liquid guide port 121 exposed on the liquid guide component 130 near the air outlet of the atomizing tube 110, outside air can enter the ventilation channel 150 in a timely manner to balance the air pressure between the liquid storage chamber 211 and the atomizing core assembly 100 and the outside.

[0053] In this embodiment, the length of the liquid guide port 121 protruding from the liquid guide member 130 along the length direction of the liquid control tube 120 is greater than 1 mm.

[0054] Please refer to Figure 1 The liquid guide port 121 is aligned with the liquid inlet port 111.

[0055] Aligning the liquid guide port 121 with the liquid inlet 111 facilitates the rapid entry of the atomized matrix into the liquid guide component 130, and also allows outside air to flow directly from the liquid guide port 121 through the liquid inlet 111.

[0056] Please refer to Figure 3 In the length direction of the liquid control tube 120, the length of the liquid guide port 121 is greater than the length of the liquid inlet port 111, and the liquid guide component 130 covers the position where the liquid guide port 121 and the liquid inlet port 111 are aligned.

[0057] Setting the length of the inlet 111 to be too large or too small is not conducive to the entry of the atomizing substrate. Since the guide port 121 needs to allow the atomizing substrate to pass through while also forming a ventilation channel 150 that connects with the atomizing air channel 131, the length of the guide port 121 needs to be larger than that of the inlet 111. The guide component 130 covers the position where the guide port 121 and the inlet 111 are aligned, which helps the atomizing substrate entering the guide port 121 to be directly adsorbed onto the guide component 130.

[0058] Please refer to Figure 3 The liquid inlet 111 includes multiple inlets, which are spaced apart around the side wall of the atomizing tube 110. The liquid guide port 121 includes multiple inlets, which are spaced apart around the side wall of the liquid control tube 120, and the liquid guide port 121 corresponds to the liquid inlet 111 one by one.

[0059] Multiple liquid inlets 111 and liquid guides 121 are provided at the same time, so that air can enter the liquid inlets 111 from all sides of the liquid control tube 120, which helps to make the atomized matrix on the liquid guide 130 more evenly distributed and further improves the taste of the aerosol.

[0060] Please refer to Figure 1 The atomizing tube 110 has a first positioning structure 112 on its side wall, and the liquid control tube 120 has a second positioning structure 122 on its side wall. The second positioning structure 122 cooperates with the first positioning structure 112 to align the liquid guide port 121 with the liquid inlet 111. In this embodiment, both the first positioning structure 112 and the second positioning structure 122 are grooves, and the grooves are aligned when the liquid control tube 120 is inserted into the atomizing tube 110. In other embodiments, the first positioning structure 112 can be either a protrusion or a groove, while the second positioning structure 122 has a different design; or, the first positioning structure 112 can be either a snap-fit ​​or a slot, while the second positioning structure 122 has a different design.

[0061] The design of the first positioning structure 112 and the second positioning structure 122 allows for convenient and quick alignment of the liquid guide port 121 with the liquid inlet port 111 for installation.

[0062] Please refer to Figure 3 The liquid guide port 121 is elongated and extends along the length of the liquid control tube 120.

[0063] The elongated liquid guide port 121 helps to form the air exchange channel 150 and shortens the air path of the air exchange channel 150, making it convenient to balance the air pressure of the electronic atomizing device 200 and the outside air pressure in a timely manner.

[0064] In this embodiment, the liquid guide port 121 is a rectangular structure or a trapezoidal structure.

[0065] Please refer to Figure 2-3 The atomizing core 140 includes an atomizing support 141, an inner casing 142, a fiberglass tube 143, and a heating element 144. The heating element 144 is disposed on the atomizing surface of the inner casing 142. The inner casing 142 and the fiberglass tube 143 are disposed within the atomizing support 141, and the inner casing 142 is connected to the fiberglass tube 143 along the length of the atomizing support 141 to form an atomizing airway 131. The atomizing support 141 is disposed within the liquid guiding component 130. The inner casing 142 is inner cotton. More specifically, the atomizing support 141 has a tubular structure, and the surface of the atomizing support 141 also has a liquid inlet opening, through which the atomizing matrix enters the inner cotton. Furthermore, the atomizing airway 131 formed by the inner casing 142 and the fiberglass tube 143 is a part of the entire atomizing airway 131.

[0066] Since the liquid guiding component 130 is made of porous liquid guiding cotton material, when the heating element 144 heats the atomizing matrix to generate aerosol, the aerosol will enter the liquid guiding cotton, reducing the amount of aerosol being absorbed. The glass fiber tube 143 can form an atomizing air channel 131 in the liquid guiding cotton, which can minimize the amount of aerosol entering the liquid guiding cotton.

[0067] Please refer to Figure 2-3 The atomizing core assembly 100 also includes a base 160, with an atomizing tube 110, a liquid control tube 120, and a liquid guide 130 disposed on the base 160. The base 160 is disposed at the bottom of the atomizing chamber 221 to support the atomizing core assembly 100.

[0068] Please refer to Figure 2-3 The atomizing core assembly 100 also includes a support 170, on which the pins of the heating element 144 are mounted. The support 170 is used to mount the base 160 and to fix the atomizing core assembly 100 in the atomizing chamber 221.

[0069] Example 3

[0070] This embodiment provides an electronic atomizing device 200. Please refer to [reference needed]. Figure 1-5The electronic atomizing device 200 includes an atomizing chamber 221, a liquid storage chamber 211, and an atomizing core assembly 100 as described in Example 1. The atomizing core assembly 100 is disposed in the atomizing chamber 221. The liquid storage chamber 211 is disposed at a distance from the atomizing chamber 221. The liquid storage chamber 211 is used to store the atomizing matrix and to supply the atomizing matrix to the atomizing core assembly 100.

[0071] Please refer to Figure 5 The electronic atomizing device 200 also includes a liquid inlet switch assembly 230. The liquid storage chamber 211 has a liquid outlet 2111, which is used to connect the liquid storage chamber 211 and the atomizing chamber 221. The liquid inlet switch assembly 230 is disposed at the liquid outlet 2111 and can close or open the liquid outlet 2111.

[0072] The liquid inlet switch assembly 230 controls the opening and closing of the liquid outlet 2111. Before the electronic atomizing device 200 is activated, the liquid outlet 2111 is closed to prevent the atomizing matrix from leaking into the atomizing chamber 221. After the electronic atomizing device 200 is activated but not being aspirated, the liquid inlet switch assembly 230 closes the liquid outlet 2111 to control the amount of atomizing matrix entering the atomizing chamber 221, and also to prevent the atomizing matrix from leaking into the atomizing chamber 221.

[0073] Please refer to Figure 5 The electronic atomizing device 200 includes a housing assembly 210 and an inner housing 220. The inner housing 220 is disposed within the housing assembly 210, and the inner housing 220 and the inner wall of the housing assembly 210 define a liquid storage chamber 211. The atomizing chamber 221 is located within the inner housing 220. Furthermore, a first sealing member 240 is provided on the side of the inner housing 220 facing the liquid storage chamber 211 for sealing the liquid storage chamber 211.

[0074] Please refer to Figure 5 The atomizing tube 110 extends from the atomizing chamber 221 of the inner shell 220 and passes through the liquid storage chamber 211, communicating with the nozzle 290. The atomizing tube 110 and the nozzle 290 are sealed together by a second sealing element 241 to prevent aerosol from flowing out from the gap between them. Additionally, a filter cotton 291 is provided between the second sealing element 241 and the nozzle 290 to absorb condensate.

[0075] Please refer to Figure 5 The liquid storage chamber 211 and the second sealing element 241 are also provided with a liquid injection hole 2112 and a liquid injection plug 2113 is provided in the liquid injection hole 2112. When the atomizing matrix in the liquid storage chamber 211 is consumed, the atomizing matrix can be replenished into the liquid storage chamber 211 through the liquid injection hole 2112, thereby reusing the electronic atomizing device 200 and reducing the cost of use.

[0076] In this embodiment, the liquid inlet switch assembly 230 is partially exposed outside the housing assembly 210 for user convenience.

[0077] In this embodiment, please refer to Figure 5 The electronic atomizing device 200 also includes a power supply 250, which is disposed inside the housing assembly 210 and is electrically connected to the atomizing core 140 to supply power to the atomizing core assembly 100.

[0078] Please refer to Figure 5 The electronic atomizing device 200 also includes a circuit board 260, a power supply 250, and an atomizing core 140, all of which are electrically connected to the circuit board 260.

[0079] Please refer to Figure 5 The electronic atomizing device 200 is also provided with a condensation chamber 270, which is located below the atomizing chamber 221. The condensation chamber 270 is provided with absorbent cotton 280 to absorb the condensate flowing down from the atomizing chamber 221.

[0080] Please refer to Figure 5 The circuit board 260 is located below the condensation chamber 270 and is connected to the bottom of the condensation chamber 270 via a third seal 242 to prevent condensate from flowing onto the circuit board 260. The third seal 242 is a sealing silicone sealant.

[0081] Please refer to Figure 5 The atomizing chamber 221 and the condensing chamber 270 are connected by a fourth seal 243, which is used to seal the electrodes of the atomizing core assembly 100 and the circuit board 260 to prevent short circuits.

[0082] Please refer to Figure 4 The outer casing assembly 210 includes a front cover 213, a rear cover 214, an upper shell 215, and a bottom shell 216. The upper shell 215 is integrally formed with the mouthpiece 290, and the front cover 213 and the rear cover 214 are connected via the upper shell 215 and the bottom shell 216. Additionally, a display screen 2131 is provided on the front cover 213. The display screen 2131 is electrically connected to the circuit board 260 and is used to display the operating mode of the electronic atomizing device 200, the content of the atomizing matrix, and the power level of the power supply 250. It can also display other patterns to further enhance the aesthetics of the electronic atomizing device 200.

[0083] An air inlet 212 is also provided on the bottom shell 216 to facilitate the entry of outside air, which then enters the atomizing chamber 221 through the condensation chamber 270. It should be noted that the liquid inlet switch assembly 230 is exposed to the outer shell assembly 210 through the air inlet 212.

[0084] More specifically, the liquid inlet switch assembly 230 includes a plunger 231, a retainer 232, and a presser 233. The plunger 231 is disposed at the liquid outlet 2111. The retainer 232 is elastically disposed within the housing assembly 210 by a spring (not shown), and both ends of the retainer 232 can be connected to the plunger 231 and the presser 233, respectively. The presser 233 partially protrudes from the air inlet 212. Pressing the presser 233 drives the retainer 232 to push the plunger 231 to move, thereby opening or closing the liquid outlet 2111. When the pressing force on the presser 233 is removed, the spring can return to its original position, thereby causing the retainer 232 to drive the plunger 231 to block the liquid outlet 2111.

[0085] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
