[0036] As Figure 1 shown, an embodiment of the present utility model provides a soda water machine, which includes a water bottle 1, a gas cylinder assembly 2 and a bottle cap assembly.

[0037] The water bottle 1 contains drinking water, and an air inlet channel is provided on the water bottle 1.

[0038] The gas cylinder assembly 2 includes a gas cylinder 20 for storing carbonated gas and a trachea 21 communicated with the gas cylinder 20. The outlet end of the trachea 21 can be inserted into the air inlet channel. After the gas cylinder 20 is opened, the carbonated gas in the gas cylinder 20 can enter the air inlet channel along the trachea 21. At this time, the carbonated gas enters into the water bottle 1 to carbonate the drinking water in the water bottle 1.

[0039] The bottle cap assembly is connected to the water bottle 1 and is used to seal the bottle mouth of the water bottle 1. The bottle cap assembly has an air cartridge 4 and a puncture needle 1. Among them, the air cartridge 4 is used to store carbonated gas. When the bottle cap assembly is connected to the water bottle 1, the puncture needle 1 can puncture the air cartridge 4 so that the carbonated gas released by the air cartridge 4 enters the water bottle 1.

[0040] In this way, when the user goes out, only the bottle cap assembly and the water bottle 1 can be carried. Outside, by only rotating the cap body 5, the carbonated gas in the air cartridge 4 can be injected into the water bottle 1 to produce soda water, as shown in Figure 3 shown; when the user is at home, the carbonated gas can be injected into the water bottle 1 only through the gas cylinder 20 to produce soda water, as shown in Figure 2 shown. Of course, the user can also use the air cartridge 4 and the gas cylinder 20 at the same time to produce soda water.

[0041] Therefore, the soda water machine in this embodiment takes into account both cylinder - type and cartridge - type devices, saving usage costs and facilitating the preparation of soda water outdoors. Its structural principle is simple and reasonable, and the operation is convenient and fast.

[0042] Continuing as Figure 1 shown, in some embodiments, the bottle cap assembly mainly includes a bracket assembly 3 and a cover body 5.

[0043] The bracket assembly 3 is used to abut against the mouth of the water bottle 1. The bracket assembly 3 is provided with a receiving cavity 32, a puncturing needle 33 disposed in the receiving cavity 32, and a gas passage 34 communicating the interior of the water bottle 1 and the receiving cavity 32.

[0044] The cartridge 4 can be detachably placed in the receiving cavity 32 on the bracket assembly 3, and the interior of the cartridge 4 is used to store carbonated gas. The carbonated gas stored in the cartridge 4 and the gas cylinder 20 can be the same, such as carbon dioxide gas.

[0045] The cover body 5 is detachably connected to the mouth of the water bottle 1, such as by screw connection, for sealing the mouth of the water bottle 1. When the cover body 5 is connected to the water bottle 1, the cover body 5 can push the cartridge 4 downward to cause the puncturing needle 33 to pierce the cartridge 4. At this time, the carbonated gas released from the cartridge 4 can enter the water bottle 1 through the gas passage 34 to carbonate the drinking water in the water bottle 1.

[0046] As Figure 4 shown, in some embodiments, the bracket assembly 3 includes an air cartridge bracket 30 and a sealing elastic member 31. The receiving cavity 32 and the gas passage 34 are both provided on the air cartridge bracket 30. When the bracket assembly 3 seals the mouth of the water bottle 1, the air cartridge bracket 30 is in sealed butt - joint with the mouth of the water bottle 1 through the sealing elastic member 31. Through this sealing elastic member 31, the carbonated gas in the water bottle 1 can be prevented from flowing out through the mouth.

[0047] As Figure 4 shown, in some embodiments, the receiving cavity 32 on the air cartridge bracket 30 is formed by a depression from its top end. The cartridge 4 can be directly placed in the receiving cavity 32 from the top of the air cartridge bracket 30, and the puncturing needle 33 is disposed at the bottom of the receiving cavity 32. When the cover body 5 is connected to the water bottle 1, the cover body 5 can seal the receiving cavity 32. In this way, after the cartridge 4 is punctured, it can be concentrated in the receiving cavity 32 to avoid leakage.

[0048] In some embodiments, when the cover body 5 is connected to the water bottle 1, the inner bottom surface of the cover body 5 can abut against the cartridge 4, thereby pushing the cartridge 4 downward, so that the cartridge 4 abuts against the puncturing needle 33 and is then punctured by the puncturing needle 33.

[0049] Preferably, the height of the gas cartridge 4 is slightly greater than the height of the receiving cavity 32. When the water bottle 1 is installed with the cover 5, the cover 5 can directly push against the gas cartridge 4 to move downward, so that the puncturing needle 33 punctures the gas cartridge 4 to release the carbonated gas inside the gas cartridge 4.

[0050] Of course, in some other embodiments, the cover 5 can also push against the gas cartridge 4 to move downward through an intermediate member or other transmission mechanisms.

[0051] In some embodiments, a protruding portion 51 extending downward is provided on the inner bottom surface of the cover 5. The protruding portion 51 faces the receiving cavity 32 on the gas cartridge support 30. When the cover 5 is connected to the water bottle 1, the cover 5 can push against the gas cartridge 4 to move in the direction of the puncturing needle 33 through the protruding portion 51.

[0052] Preferably, the protruding portion 51 of this embodiment can be an integral structure with the cover 5, which is convenient for processing. Regarding the specific structure of the protruding portion 51 of this embodiment, the present application does not make specific limitations, and it can be a hemispherical structure or a cylindrical structure.

[0053] The gas cartridge 4 of this embodiment can be a cavity structure surrounded by aluminum alloy sheets. The thickness of the aluminum alloy is relatively thin, and the puncturing needle 33 can puncture the gas cartridge 4 without too much pressure to release the carbonated gas.

[0054] As Figure 3 and Figure 4 shown, in some embodiments, the sealing elastic member 31 in the support assembly 3 is an annular body.

[0055] The shape of the sealing elastic member 31 is adapted to the shape of the bottle mouth of the water bottle 1. The sealing elastic member 31 can abut against the bottle mouth of the water bottle 1, and a ring-shaped support platform 310 protruding inward is provided on the inner peripheral wall of the sealing elastic member 31.

[0056] The gas cartridge support 30 includes a cylindrical portion 300 and an annular platform 301 provided on the outer peripheral wall of the cylindrical portion 300. Among them, the top end of the cylindrical portion 300 forms the top end of the gas cartridge support 30, that is, a receiving cavity 32 for placing the gas cartridge 4 is provided at the top end of the cylindrical portion 300.

[0057] The inner diameter of the annular platform 301 on the gas cartridge support 30 of this embodiment is less than or equal to the inner diameter of the sealing elastic member 31. The cylindrical portion 300 of the gas cartridge support 30 can pass through the sealing elastic member 31 and extend into the interior of the water bottle 1, so that the annular platform 301 on the gas cartridge support 30 can abut against the support platform 310 of the sealing elastic member 31.

[0058] In some embodiments, the puncturing needle 33 is vertically arranged in the gas cartridge support 30. The top end of the puncturing needle 33 is a pointed body and extends into the receiving cavity 32, and the bottom end of the puncturing needle 33 extends into the gas passage 34.

[0059] The puncturing needle 33 is provided with an inner needle channel that communicates with the gas channel 34 and the accommodating cavity 32. When the puncturing needle 33 punctures the gas cartridge 4, the carbonated gas in the gas cartridge 4 can enter the gas channel 34 through the inner needle channel and then enter the gas cylinder 20.

[0060] As Figure 1 shown, in some embodiments, the bottom of the water bottle 1 is provided with an air inlet channel and a first one-way valve 10 disposed in the air inlet channel. The trachea 21 connected to the gas cylinder 20 can be inserted into the air inlet channel, and the carbonated gas in the gas cylinder 20 enters the water bottle 1 through the first one-way valve.

[0061] After the outlet end of the trachea 21 is pulled out of the air inlet channel, the first one-way valve 10 can automatically block the air inlet channel, preventing the water in the water bottle 1 from flowing out through the air inlet channel. The specific structure and working principle of the first one-way valve 10 belong to the prior art and will not be elaborated here.

[0062] As Figure 4 shown, a second one-way valve 35 is disposed in the gas channel 34 on the gas cartridge bracket 30 of this embodiment, and the structure of the second one-way valve 35 is the same as that of the first one-way valve 10.

[0063] After the carbonated gas is released by the gas cartridge 4, the air pressure in the accommodating cavity 32 increases, and the carbonated gas can push the second one-way valve 35 downward to open the gas channel 34. In this way, the carbonated gas in the accommodating cavity 32 can enter the water bottle 1 through the gas channel 34. As the carbonated gas continuously enters the water bottle 1, the pressure in the accommodating cavity 32 continuously decreases. When the air pressure in the water bottle 1 is greater than the air pressure in the accommodating cavity 32, the second one-way valve 35 moves upward to automatically block the gas channel 34.

[0064] As Figure 1 and Figure 3 shown, the cover body 5 is provided with a safety valve 50 for discharging the gas in the water bottle 1. The safety valve 50 can be disposed in the area on the cover body 5 between the gas cartridge bracket 30 and the sealing elastic member 31. After the drinking water in the water bottle 1 is carbonated, the remaining gas in the water bottle 1 is discharged through the safety valve 50, facilitating the user to remove the cover body 5.

[0065] As Figure 1 and Figure 2 shown, in some embodiments, the soda water machine further includes a machine base 6, and the gas cylinder 20 can be fixed on the machine base 6. When it is necessary to fill the water bottle 1 with carbonated gas through the gas cylinder 20, the gas cylinder 20 can be directly placed on the machine base 6, and carbonated gas is injected into the water bottle 1 through the gas cylinder 20.

[0066] The gas cylinder 20 can be vertically arranged on the machine base 6. On one side of the gas cylinder 20 on the machine base 6, there is a support platform 310 for placing the water bottle 1. The outlet end of the air pipe 21 connecting the gas cylinder 20 can be connected with a plug 25, and the plug 25 is fixed on the support platform 310 of the machine base 6. When the water bottle 1 is placed on the support platform, the plug 25 can automatically insert into the air inlet channel at the bottom of the water bottle 1. At this time, when the gas cylinder 20 is opened, the carbonated gas in the gas cylinder 20 can be injected into the water bottle 1.

[0067] There are various structures for opening the gas cylinder 20 to release carbonated gas in this embodiment. For example, as Figure 1 and Figure 2 shown, inside the bottle mouth of the gas cylinder 20, there is a piston 22 that can move up and down. On the outer peripheral wall at the top of the gas cylinder 20, there are air holes, and the inlet end of the air pipe 21 is communicated with the air holes, and the piston 22 can be used to block the air holes.

[0068] Furthermore, the gas cylinder assembly 2 further includes a lever 24 and a spring 23. The first end of the lever 24 is rotatably connected to the machine base 6, and the first end of the lever 24 is also rotatably connected to the top of the piston 22. The second end of the lever 24 is suspended. The spring 23 is used to elastically connect the position of the lever 24 near the first end and the machine base 6. When pressing down the lever 24, the lever 24 can drive the piston 22 to move upward, thereby opening the air hole of the gas cylinder 20. At this time, the carbonated gas in the gas cylinder 20 can enter the air pipe 21. When the user releases the lever 24, under the action of the spring 23, the lever 24 rotates upward, and the piston 22 moves downward, which can block the air hole on the gas cylinder 20 again.

[0069] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
