Obviously, the following described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] In order to make the technical solutions and the embodiments of the present application clearer and more understandable, the following introduces several preferred specific embodiments for implementing the technical solutions of the present application.

[0039] It should be noted that the orientation words such as "inner", "outer", "front", "rear", "left", and "right" in the present text are described based on the product use state as the reference object. Obviously, the use of the corresponding orientation words does not constitute a limitation on the protection scope of the present application.

[0040] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 The present application provides a bubble water bottle, which comprises a bottle body 100 and an air inlet bottle cap 200 threadedly connected with the bottle mouth of the bottle body 100. An L-shaped interface 201 is arranged on the outer wall of the air inlet bottle cap 200, and is used for detachably connecting with a water bottle connecting seat of a bubble water machine.

[0041] The air inlet bottle cap 200 comprises an outer cap 210 and an air inlet base 220, and the outer cap 210 is clamped and fixed with the air inlet base 220. An L-shaped interface 201 is arranged on the outer wall of the outer cap 210, and the top surface of the outer cap 210 is provided with an air inlet 202 at the center, which is used for connecting the air charging pipe of the sparkling water machine.

[0042] The top surface of the air inlet base 220 is respectively provided with an air inlet channel 221 and an exhaust channel 222 which are vertically through, and the air inlet channel 221 is arranged opposite to the air inlet 202. The upper end of the air inlet channel 221 is provided with a first chamber, and an air inlet one-way valve 230 is inserted and arranged in the first chamber. The lower end of the air inlet channel 221 is threadedly connected with an air inlet spout 240, which is used for injecting carbon dioxide gas into the bottle body 100. The upper end of the exhaust channel 222 is provided with a second chamber, and an overpressure alarm valve 250 is inserted and arranged in the second chamber, which is used for automatically emitting an alarm sound when the air pressure in the bottle body 100 exceeds a preset value.

[0043] The air inlet base 220 is threadedly connected with the bottle mouth of the bottle body 100, and the end surfaces of the two are provided with a sealing ring 203, which can realize the functions of tight sealing and loosening exhaust. After hearing the overpressure alarm sound, the air inlet bottle cap 200 can be loosened, and part of the carbon dioxide gas in the bottle body 100 can be discharged from the sealing ring 203, and then the air inlet bottle cap 200 is tightly sealed again, so as to ensure that the carbon dioxide gas in the bottle body 100 will not escape, and the taste of the sparkling water in the bottle body 100 can be kept for a long time under the condition of safe use.

[0044] In the embodiment, two overpressure alarm valves 250 are arranged, which are respectively installed on two independent exhaust channels 222. The opening pressures of the two overpressure alarm valves are different, and the opening pressure of one of them is greater than that of the other. When the pressure in the bottle body 100 is too large, the two overpressure alarm valves 250 are simultaneously started to rapidly reduce the pressure. The overpressure alarm valve with lower opening pressure can set a lower alarm pressure to improve safety.

[0045] As shown in Figure 3 , Figure 5 , the air inlet one-way valve 230 comprises a one-way valve body 231, the lower end of the one-way valve body 231 is provided with a gas outlet column 232, the middle part of the gas outlet column 232 is provided with a radial through hole 233, the top surface of the one-way valve body 231 is provided with an axial hole 234, and the lower end of the axial hole 234 is communicated with the radial through hole 233. An elastic rubber sleeve 235 is sleeved on the outer side surface of the gas outlet column 232, which is used for opening or closing the radial through hole 233. In the initial state, the elastic rubber sleeve 235 seals the radial through hole 233; when the carbon dioxide gas enters the axial hole 234 through the air inlet 202, the pressure gas props open the elastic rubber sleeve 235 through the radial through hole 233, and enters the air inlet spout 240 through the gap between the inner wall of the elastic rubber sleeve 235 and the outer wall of the gas outlet column 232 which is proped open, and then is injected into the bottle body 100 to prepare the sparkling water.

[0046] The air inlet one-way valve has simple structure, high reliability and long service life.

[0047] The lower end of the air outlet column 232 is provided with an annular flange 236 for axially limiting the elastic rubber sleeve 235 to prevent the elastic rubber sleeve 235 from falling off and improve reliability. The lower end of the annular flange 236 is in the shape of a truncated cone to facilitate the installation of the elastic rubber sleeve 235 from bottom to top.

[0048] As shown in Figure 3 , Figure 6 , Figure 7 The overpressure alarm valve 250 includes an alarm valve body 251 and an alarm valve core 252. The lower end of the alarm valve body 251 is fixedly connected with the second chamber in a threaded manner. The alarm valve body 251 is provided with a stepped hole 253 with a small upper end and a large lower end in the axial direction. The alarm valve core 252 is slidably arranged below the stepped hole 253. An overpressure spring 254 is arranged in the stepped hole 253. The overpressure spring 254 has a corresponding elasticity according to a preset alarm pressure. The lower end of the overpressure spring 254 abuts against the top surface of the alarm valve core 252 and presses the bottom surface of the alarm valve core 252 against the stepped surface of the exhaust passage 222 of the air inlet base 220 to achieve sealing. A gap is arranged between the outer wall of the alarm valve core 252 and the inner wall of the second chamber for generating an alarm sound when the overpressure gas in the bottle body 100 flows through the gap.

[0049] In the initial state, the bottom surface of the alarm valve core 252 seals the exhaust passage 222 under the action of the overpressure spring 254.

[0050] When the pressure in the bottle body 100 is greater than the pre-pressure of the overpressure spring 254, the pressure gas pushes the alarm valve core 252 to move upward, the exhaust passage 222 is opened, and the pressure gas in the bottle body 100 is discharged through the gap between the outer wall of the alarm valve core 252 and the inner wall of the second chamber. Since the gap is small, the gas flow generates an alarm sound. After the user hears the alarm sound, the bubble water machine can be closed, the bubble water bottle can be removed, the air inlet bottle cap 200 can be loosened, and the pressure in the bottle body 100 can be reduced.

[0051] When the pressure in the bottle body 100 is less than the pressure of the overpressure spring 254, the overpressure spring 254 pushes the alarm valve core 252 to move downward to automatically seal the exhaust passage 222.

[0052] The lower end outer wall of the alarm valve body 251 is further provided with a notch 255, which is communicated with the inner cavity of the stepped hole 253, and the pressure gas discharged through the gap between the outer wall of the alarm valve core 252 and the inner wall of the second chamber can enter the stepped hole 253 through the notch 255 and then be discharged through the upper end of the stepped hole 253. Obviously, this mode can realize automatic exhaust, and even if the gas bottle cap is not loosened in time to exhaust, the gas pressure in the bottle body 100 will not accumulate and rise to be dangerous.

[0053] In the scheme, the alarm valve core 252 is combined by a sliding sleeve 2521 and a sealing element 2522. Specifically, the sliding sleeve 2521 is in a cylindrical shape and is provided with an axial through hole, and the sealing element 2522 has a plug shaft and a sealing pad arranged at the lower end of the plug shaft, the plug shaft is inserted into the axial through hole of the sliding sleeve 2521 from bottom to top, and the sealing pad is pressed against the bottom surface of the sliding sleeve 2521. Among them, the sliding sleeve 2521 and the sealing element 2522 can be made of different materials respectively, which not only ensures the rigidity of smooth sliding of the sliding sleeve 2521, but also ensures the flexible deformation ability of the sealing function of the sealing element 2522.

[0054] In combination with the description of the above specific embodiments, the bubble water bottle and the gas inlet bottle cap thereof provided by the utility model have the following advantages compared with the prior art:

[0055] First, the gas inlet one-way valve and the overpressure alarm valve are arranged on the gas inlet bottle cap, the waste caused by the escape of carbon dioxide in the bottle body when the bubble water bottle is taken down can be avoided by using the gas inlet one-way valve, and the danger caused by the overhigh pressure in the bottle body can also be avoided.

[0056] Second, the gas inlet one-way valve has simple structure, high reliability and long service life. When the gas leakage phenomenon occurs, the elastic rubber sleeve can be replaced to solve the gas leakage problem, which is convenient to maintain and low in cost.

[0057] Third, the overpressure alarm valve alarms by whistle sound, the reminding effect is obvious, and the automatic exhaust function is provided, so that the safety is improved.

[0058] Finally, it should be noted that the terms "comprising", "including" or any other variant thereof used in this text are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.
