[0005] To address the aforementioned technical problems in the existing technology, this utility model provides a soda water machine. This soda water machine combines both cylinder-type and cartridge-type designs, featuring a simple and reasonable structure and convenient and quick operation.

[0006] The technical solution adopted in this embodiment of the utility model is:

[0007] A soda maker, comprising:

[0008] Aquarius

[0009] A gas cylinder assembly includes a gas cylinder for storing carbonic acid gas and a gas pipe connected to the gas cylinder, the gas pipe being able to connect to a water bottle so that the carbonic acid gas in the gas cylinder enters the water bottle through the gas pipe;

[0010] A bottle cap assembly has a gas cartridge and a piercing needle. The gas cartridge is used to store carbonic acid gas. When the bottle cap assembly is connected to the water bottle, the piercing needle can pierce the gas cartridge to allow the carbonic acid gas released by the gas cartridge to enter the water bottle.

[0011] Furthermore, the bottle cap assembly includes:

[0012] A support assembly is used to abut against the mouth of the water bottle. The support is provided with a receiving cavity, a piercing needle and a gas channel. The piercing needle is located in the receiving cavity, which is used to hold the gas cartridge. The carbonized gas released by the gas cartridge can enter the water bottle through the gas channel.

[0013] A cap, connected to the water bottle, is used to seal the bottle opening. When connected to the water bottle, the cap can push against the movement of the gas cartridge, allowing the piercing needle to puncture the gas cartridge. This structure facilitates the installation of the gas cartridge.

[0014] Furthermore, the support assembly includes a gas spring support and a sealing elastic element. The receiving cavity is disposed on the gas spring support, and the gas spring support is sealed to the bottle opening of the water bottle through the sealing elastic element. This structure prevents carbonated gas entering the water bottle from flowing out through the bottle opening.

[0015] Furthermore, the receiving cavity is formed by a downward indentation at the top of the gas cartridge support, and the piercing needle is located at the bottom of the receiving cavity. This structure is simple and facilitates puncturing the gas cartridge.

[0016] Furthermore, a protrusion is provided on the inner bottom surface of the cap. When the cap is connected to the water bottle, the protrusion can push the gas cartridge to move. By providing the protrusion, the gas cartridge can be easily pushed towards the puncture needle.

[0017] Furthermore, the sealing elastic element is an annular body, the sealing elastic element can abut against the mouth of the water bottle, and a support platform is provided on the inner peripheral wall of the sealing elastic element;

[0018] The gas spring support includes a column and an annular platform disposed on the outer peripheral wall of the column, and the top of the column forms the top of the gas spring support.

[0019] The cylindrical portion of the gas spring support can extend into the water bottle through the sealing elastic element, and the annular platform rests against the support platform. This structure facilitates the assembly of the sealing elastic element and the gas spring support.

[0020] Furthermore, the first end of the piercing needle is pointed and extends into the receiving cavity, while the second end of the piercing needle extends into the gas channel. The piercing needle has an internal channel connecting the gas channel and the receiving cavity. This structure simplifies the structure of the gas cartridge support.

[0021] Furthermore, the gas bomb has a cavity structure made of aluminum alloy.

[0022] Furthermore, the bottom of the water bottle is provided with an air inlet channel and a first one-way valve located within the air inlet channel, and the air tube can be inserted into the air inlet channel;

[0023] And / or, a second one-way valve is provided in the gas channel, allowing the carbonated gas released by the gas cartridge to enter the water bottle through the second one-way valve. This structure prevents the carbonated gas entering the water bottle from flowing out again through the gas channel.

[0024] Furthermore, the cap is provided with a safety valve for venting gas from the water bottle.

[0025] Furthermore, the soda machine also includes a base, on which the gas cylinder is disposed, and on which a support platform for placing the gas cylinder is provided.

[0026] Compared with the prior art, the beneficial effects of the embodiments of this utility model are as follows:

[0027] This invention relates to a soda maker that allows users to carry only the cap assembly and a water bottle when out and about. Outside, simply rotating the cap assembly injects the carbonated gas from the gas cartridge into the water bottle. At home, the user can inject the carbonated gas directly into the water bottle using only the gas cartridge. Therefore, this soda maker combines the features of both cylinder and gas cartridge types, saving on operating costs and providing convenient soda preparation on the go. Its simple and reasonable structure and operation make it easy and quick to use.

[0037] As shown in Figure 1, this embodiment of the present invention provides a soda water machine, which includes a water bottle 1, a gas cylinder assembly 2, and a bottle cap assembly.

[0038] Water bottle 1 contains drinking water and has an air intake channel.

[0039] The gas cylinder assembly 2 includes a gas cylinder 20 for storing carbonated gas and a gas pipe 21 connected to the gas cylinder 20. The outlet end of the gas pipe 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 through the gas pipe 21. At this time, the carbonated gas enters the water bottle 1 to carbonize the drinking water in the water bottle 1.

[0040] The bottle cap assembly is connected to the water bottle 1 and is used to seal the mouth of the water bottle 1. The bottle cap assembly has a gas cartridge 4 and a piercing needle 1. The gas cartridge 4 is used to store carbonized gas. When the bottle cap assembly is connected to the water bottle 1, the piercing needle 1 can pierce the gas cartridge 4 to allow the carbonized gas released by the gas cartridge 4 to enter the water bottle 1.

[0041] Thus, when users go out, they can carry only the cap assembly and water bottle 1. While outside, they can simply rotate the cap 5 to inject the carbonated gas from the gas cartridge 4 into water bottle 1 to make soda water, as shown in Figure 3. When users are at home, they can inject the carbonated gas into water bottle 1 using only the gas cylinder 20 to make soda water, as shown in Figure 2. Of course, users can also use both the gas cartridge 4 and the gas cylinder 20 simultaneously to make soda water.

[0042] Therefore, the soda water machine in this embodiment combines both cylinder-type and gas cartridge-type equipment, which not only saves on usage costs but also makes it convenient to prepare soda water outside. Its structure and principle are simple and reasonable, and it is easy and quick to operate.

[0043] As shown in Figure 1, in some embodiments, the bottle cap assembly mainly includes a support assembly 3 and a cap body 5.

[0044] The support assembly 3 is used to abut against the mouth of the water bottle 1. The support assembly 3 is provided with a receiving cavity 32, a piercing needle 33 disposed in the receiving cavity 32, and a gas channel 34 connecting the interior of the water bottle 1 and the receiving cavity 32.

[0045] The gas cartridge 4 can be detachably placed in the receiving cavity 32 on the support assembly 3, and the interior of the gas cartridge 4 is used to store carbonic acid gas. The carbonic acid gas stored in the gas cartridge 4 and the gas cylinder 20 can be the same, for example, both are carbon dioxide gas.

[0046] The cap 5 is detachably connected to the mouth of the water bottle 1, for example, by a threaded connection, to seal the mouth of the water bottle 1. When the cap 5 is connected to the water bottle 1, the cap 5 can push the gas cartridge 4 downwards, causing the piercing needle 33 to pierce the gas cartridge 4. At this time, the carbonated gas released from the gas cartridge 4 can enter the water bottle 1 through the gas channel 34 to carbonize the drinking water in the water bottle 1.

[0047] As shown in Figure 4, in some embodiments, the support assembly 3 includes a gas spring support 30 and a sealing elastic element 31. The receiving cavity 32 and the gas channel 34 are both located on the gas spring support 30. When the support assembly 3 seals the mouth of the water bottle 1, the gas spring support 30 is sealed to the mouth of the water bottle 1 via the sealing elastic element 31. This sealing elastic element 31 prevents the carbonated gas from the water bottle 1 from leaking out through the mouth.

[0048] As shown in Figure 4, in some embodiments, the receiving cavity 32 on the gas cartridge holder 30 is formed by a downward indentation from its top. The gas cartridge 4 can be placed directly into the receiving cavity 32 from the top of the gas cartridge holder 30, and the piercing needle 33 is located at the bottom of the receiving cavity 32. When the cap 5 is connected to the water bottle 1, the cap 5 can seal the receiving cavity 32, so that after the gas cartridge 4 is punctured, it can be concentrated in the receiving cavity 32, preventing leakage.

[0049] In some embodiments, when the cap 5 is connected to the water bottle 1, the inner bottom surface of the cap 5 can abut against the gas ball 4, thereby pushing the gas ball 4 to move downward, so that the gas ball 4 abuts against the piercing needle 33 and is pierced by the piercing needle 33.

[0050] Preferably, the height of the gas cartridge 4 is slightly greater than the height of the receiving cavity 32. When the cap 5 is installed on the water bottle 1, the cap 5 can directly push the gas cartridge 4 downward, thereby causing the piercing needle 33 to puncture the gas cartridge 4 and release the carbonized gas inside the gas cartridge 4.

[0051] Of course, in some other embodiments, the cover 5 may also be moved downward against the air spring 4 by means of an intermediate component or other transmission mechanism.

[0052] In some embodiments, the inner bottom surface of the cover 5 is provided with a downwardly extending protrusion 51, which is opposite to the receiving cavity 32 on the gas cartridge holder 30. When the cover 5 is connected to the water bottle 1, the cover 5 can push the gas cartridge 4 towards the piercing needle 33 through the protrusion 51.

[0053] Preferably, the protrusion 51 in this embodiment can be an integral structure with the cover 5, thereby facilitating processing. The specific structure of the protrusion 51 in this embodiment is not specifically limited in this application; it can be a hemispherical structure or a cylindrical structure.

[0054] In this embodiment, the gas cartridge 4 can be a cavity structure surrounded by an aluminum alloy sheet. The aluminum alloy is relatively thin, so the piercing needle 33 can puncture the gas cartridge 4 without much pressure, thereby releasing the carbonized gas.

[0055] As shown in Figures 3 and 4, in some embodiments, the sealing elastic element 31 in the support assembly 3 is an annular body.

[0056] The shape of the sealing elastic element 31 is adapted to the shape of the bottle mouth of the water bottle 1. The sealing elastic element 31 can abut against the bottle mouth of the water bottle 1. The inner peripheral wall of the sealing elastic element 31 has an inwardly protruding ring-shaped support platform 310.

[0057] The gas canister support 30 includes a column portion 300 and an annular platform 301 disposed on the outer peripheral wall of the column portion 300. The top end of the column portion 300 forms the top end of the gas canister support 30, that is, the top end of the column portion 300 is provided with a receiving cavity 32 for placing the gas canister 4.

[0058] In this embodiment, the inner diameter of the annular platform 301 on the gas spring support 30 is less than or equal to the inner diameter of the sealing elastic member 31. The column portion 300 of the gas spring support 30 can pass through the sealing elastic member 31 and extend into the interior of the water bottle 1, thereby allowing the annular platform 301 on the gas spring support 30 to abut against the support platform 310 of the sealing elastic member 31.

[0059] In some embodiments, the puncture needle 33 is vertically disposed within the gas spring support 30, with the tip of the puncture needle 33 being pointed and extending into the receiving cavity 32, and the bottom end of the puncture needle 33 extending into the gas channel 34.

[0060] The puncturing needle 33 has an internal channel that connects the gas passage 34 and the receiving cavity 32. When the puncturing needle 33 punctures the gas cartridge 4, the carbonized gas inside the gas cartridge 4 can enter the gas passage 34 through the internal channel and then enter the gas cylinder 20.

[0061] As shown in Figure 1, in some embodiments, the bottom of the water bottle 1 is provided with an air inlet channel and a first one-way valve 10 located in the air inlet channel. The air pipe 21 connected to the gas cylinder 20 can be inserted into the air inlet channel, and the carbonized gas in the gas cylinder 20 enters the water bottle 1 through the first one-way valve.

[0062] When the outlet end of the air tube 21 is pulled out of the air inlet channel, the first one-way valve 10 automatically blocks the air inlet channel, preventing water from 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 are existing technologies and will not be described in detail here.

[0063] As shown in Figure 4, a second one-way valve 35 is provided in the gas channel 34 on the gas ball support 30 of this embodiment. The structure of the second one-way valve 35 is the same as that of the first one-way valve 10.

[0064] When the carbonized gas released by the gas cartridge 4 increases the gas pressure in the containment chamber 32, the carbonized gas can push the second one-way valve 35 downward, thereby opening the gas passage 34. In this way, the carbonized gas in the containment chamber 32 can enter the water bottle 1 through the gas passage 34. As the carbonized gas continuously enters the water bottle 1, the pressure in the containment chamber 32 continuously decreases. When the gas pressure in the water bottle 1 is greater than the gas pressure in the containment chamber 32, the second one-way valve 35 moves upward and can automatically block the gas passage 34.

[0065] As shown in Figures 1 and 3, the cap 5 is equipped with a safety valve 50 for venting gas from the water bottle 1. The safety valve 50 can be located on the cap 5 in the area between the gas spring support 30 and the sealing elastic element 31. After the drinking water in the water bottle 1 has finished carbonating, the remaining gas in the water bottle 1 is released through the safety valve 50, making it convenient for the user to remove the cap 5.

[0066] As shown in Figures 1 and 2, in some embodiments, the soda water machine also includes a base 6, and the gas cylinder 20 can be fixed on the base 6. When it is necessary to inject carbonic acid gas into the water bottle 1 through the gas cylinder 20, the gas cylinder 20 can be placed directly on the base 6, and carbonic acid gas can be injected into the water bottle 1 through the gas cylinder 20.

[0067] The gas cylinder 20 can be vertically installed on the base 6. The base 6 has a support platform on one side of the gas cylinder 20 for placing the water bottle 1. The outlet end of the gas pipe 21 connected to the gas cylinder 20 can be connected to a plug 25. The plug 25 is fixed on the support platform 310 of the base 6. When the water bottle 1 is placed on the support platform, the plug 25 can be automatically inserted into the air inlet channel at the bottom of the water bottle 1. At this time, opening the gas cylinder 20 can inject the carbonized gas in the gas cylinder 20 into the water bottle 1.

[0068] This embodiment has various structures for opening the gas cylinder 20 to release carbonized gas. For example, as shown in Figures 1 and 2, a piston 22 that can move up and down is provided inside the mouth of the gas cylinder 20. An air hole is provided on the outer peripheral wall of the top of the gas cylinder 20. The air inlet end of the gas pipe 21 is connected to the air hole. The piston 22 can be used to block the air hole.

[0069] Furthermore, the gas cylinder assembly 2 also includes a pressure rod 24 and a spring 23. The first end of the pressure rod 24 is rotatably connected to the base 6, and the first end of the pressure rod 24 is also rotatably connected to the top of the piston 22. The second end of the pressure rod 24 is suspended. The spring 23 is used to elastically connect the position of the pressure rod 24 near the first end to the base 6. When the pressure rod 24 is pressed down, the pressure rod 24 can drive the piston 22 to move upward, thereby opening the gas hole of the gas cylinder 20. At this time, the carbonized gas in the gas cylinder 20 can enter the gas tube 21. When the user releases the pressure rod 24, under the action of the spring 23, the pressure rod 24 rotates upward, and the piston 22 moves downward, which can seal the gas hole on the gas cylinder 20 again.

[0070] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
