Description

Technical Field

[0001] The utility model relates to the field of bubble water machines, in particular to a bubble water machine provided with a protective container. Background Art

[0002] A bubble water machine is a product that uses high-pressure carbon dioxide to dissolve in water to form carbonated bubble water. Such products generally include a main body and a water bottle. Water is filled into the water bottle and then installed on the main body. A carbon dioxide gas cylinder and an air path main body are arranged in the main body. An air nozzle extending into the water bottle is arranged on the air path main body. By controlling the opening of the carbon dioxide gas cylinder, high-pressure carbon dioxide gas is injected into the water in the water bottle through the air nozzle. For a current type of bubble water machine, its water bottle can swing outwards relative to the main body, so as to provide a larger space for convenient disassembly and assembly of the water bottle. However, its water bottle is directly exposed outside the bubble water machine. For example, a bubble water machine named anti-leakage and air leakage disclosed in the patent number 201922089186.3. This method actually has certain safety risks. Because the water bottle has a certain service life, and its life fluctuates with the different pressures it is under. At the same time, there are also quality differences in the water bottles produced by different manufacturers. However, it is very difficult for users to actively notice whether the water bottle needs to be replaced.

[0040] Referring to Figures 1 to 12 , a sparkling water machine provided with a protective container includes:

[0041] Main unit 10, the main unit 10 includes a mounting head 11, a gas path body 111 is pivotally connected to the bottom of the mounting head 11, an exhaust valve is provided on the gas path body 111, and a gas nozzle and a water bottle mounting position are provided at the bottom of the gas path body 111;

[0042] Protection container 20, the protection container 20 includes a fixed housing 21 and a door body 22, a protection cavity is provided in the fixed housing 21, an opening communicating with the protection cavity is provided at the front end of the fixed housing 21, the door body 22 is pivotally connected to the fixed housing 21 and can rotate along the fixed housing 21 to open and close the opening, the protection container 20 is pivotally connected to the mounting head 11, the gas path body 111 is located in the protection cavity, the protection container 20 is at the open position when it swings outward to the end of the stroke, and the protection container 20 is at the initial position when it swings inward to the end of the stroke;

[0043] When the water bottle is installed on the water bottle mounting position and the protection container 20 swings to the open position, the gas path body 111 is synchronously driven by the water bottle to switch from the working position to the disassembly and assembly position.

[0044] During operation, the water bottle is installed on the water bottle mounting position and located in the protection cavity, the door body 22 is closed. At this time, the gas path body 111 is in the working position, so that carbon dioxide gas can be injected into the water bottle to prepare sparkling water. After preparation, exhaust is carried out through the exhaust valve, and then the protection container 20 is swung towards the open position, so as to drive the water bottle and the gas path body 111 to swing to the disassembly and assembly position synchronously. Then the door body 22 is opened, and then the protection container 20 is reset to the initial position. At this time, the water bottle is tilted and exposed outside the protection container 20, which is convenient for disassembly and assembly of the water bottle. Through this solution, the water bottle is only outside the protection container 20 when it is removed or installed, and can be enclosed in the protection cavity by the door body 22 at other times, which is safer. Even if the water bottle falls off or explodes, it will only occur in the protection cavity, thus not harming the user.

[0045] In the above solution, preferably, a ring-shaped rotating frame 221 is provided at the top of the door body 22, and the ring-shaped rotating frame 221 is sleeved on the top of the fixed housing 21.

[0046] In this solution, to prevent the user from freely opening the door body 22 during the process of preparing sparkling water, it is preferred that a positioning notch 2211 is provided at the top of the door body 22, and a fixed head 30 is provided in the main body 10 or the installation head 11. A driving spring 32 is connected to the fixed head 30, and the driving spring 32 drives the fixed head 30 to swing towards the top of the door body 22. When the protection door closes the opening and the protection container 20 is in the initial position, the front end of the fixed head 30 is engaged in the positioning notch 2211. Preferably, the positioning notch 2211 is provided at the top of the annular rotating frame 221. When the water bottle swings to the disassembly and assembly position, the door body 22 is closed. Since the door body 22 is in the initial position at this time, the annular rotating frame 221 rotates under the action of the door body 22, so that the positioning notch 2211 moves to cooperate with the fixed head 30. At this time, the fixed head 30 is snapped into the positioning notch 2211 under the action of the driving spring 32, so that the door body 22 cannot rotate and thus cannot be opened. When the door body 22 needs to be opened, the protection container 20 needs to be swung from the initial position to the open position, so that the entire annular rotating frame 221 is disengaged from the cooperation with the fixed head 30, and then the door body 22 can be freely rotated to open the protection cavity. Then, when the entire protection container 20 is swung back to the initial position with the door body 22 open, the top surface of the annular rotating frame 221 abuts against the fixed head 30 and pushes it back to its original position. To further optimize the structure, it is preferred that a lock block link 31 is pivotally connected in the main body 10 or the installation head 11. The driving spring 32 is connected to the lock block link 31 and drives the lock block link 31 to swing. The end of the fixed head 30 is pivotally connected in the installation head 11. The front end of the lock block link 31 abuts against the top of the front end of the fixed head 30. The bottom of the front end of the fixed head 30 is used to cooperate with the top of the annular rotating frame 221 and the positioning notch 2211. By adding a swinging lock block link 31 to drive the fixed head 30 to swing, the overall structure is more stable and the driving spring 32 is not easily separated and detached.

[0047] In other embodiments, the fixed head 30 and the driving spring 32 can also be arranged vertically in the installation head 11.

[0048] Further optimization is carried out. To prevent the door 22 from being opened when there is still air pressure in the water bottle, it preferably includes a pneumatic lock body 40 arranged on the fixed housing 21. A pneumatic chamber 41 is arranged inside the pneumatic lock body 40. A pneumatic hole communicating with the pneumatic chamber 41 is arranged at the end of the pneumatic lock body 40. A gas guiding channel 42 extending to the bottom of the gas path main body 111 for communicating with the water bottle is arranged on the pneumatic lock body 40. The end of the gas guiding channel 42 and the pneumatic hole are respectively located at both ends of the pneumatic chamber 41. A pneumatic valve body 43 and a pneumatic valve rod 44 located at the bottom of the pneumatic valve body 43 are arranged inside the pneumatic chamber 41. The pneumatic valve rod 44 is directly opposite to the pneumatic hole. The pneumatic valve body 43 is sealed with the side wall of the pneumatic chamber 41. A reset elastic member 45 connected to the pneumatic valve body 43 or the pneumatic valve rod 44 is arranged inside the pneumatic chamber 41. A lock hole 2212 is arranged on the door 22. When the door 22 closes the opening, the pneumatic hole is directly opposite to the lock hole 2212. Thus, when the water bottle is still in a high-pressure state, the high-pressure carbon dioxide in the water bottle is transmitted into the pneumatic chamber 41 through the gas guiding channel 42, so as to push the pneumatic valve rod 44 out of the pneumatic hole, and then lock it into the lock hole 2212 on the door 22, thereby ensuring that the door 22 can only be opened after the high-pressure carbon dioxide gas in the water bottle is completely discharged. Through the two locking structures of the pneumatic lock and the fixed head 30, the stability of the door 22 is fully ensured, so that the door 22 can only be opened in a safe state. Preferably, the lock hole 2212 is arranged at the top of the door 22, and the pneumatic lock body 40 is vertically arranged in the installation machine head 11. In other embodiments, the pneumatic lock body 40 can also be arranged obliquely, and the lock hole 2212 can also be arranged on the outer surface or the inner surface of the door 22.

[0049] In this solution, the process of the exhaust valve exhausting can be controlled manually by the user. Considering the foolproof operation, it is preferably triggered when the gas path main body 111 swings to the disassembly and assembly position. Thus, during use, after the sparkling water is prepared, the user only needs to control the protection container 20 to swing to the opening position, and then the exhaust operation can be automatically carried out, so as to completely exhaust the air pressure in the water bottle. Furthermore, when the door 22 is opened, there is no extra air pressure in the water bottle.

[0050] On this basis, for optimization, it is preferred that the exhaust valve includes an exhaust valve cavity provided on the gas path main body 111 and an exhaust valve rod located in the exhaust valve cavity. An exhaust passage is provided at the front end of the exhaust valve cavity, which communicates with the bottom of the gas path main body 111 and is used to communicate with the water bottle. An exhaust hole communicating with the exhaust valve cavity is provided on the outer surface of the gas path main body 111. A guiding surface is provided inside the main body 10 or the mounting head 11 and located outside the exhaust hole. The exhaust valve rod passes through the exhaust hole and abuts against the guiding surface. An exhaust valve head for closing the exhaust passage is provided at the front end of the exhaust valve rod. When the exhaust main body swings from the working position to the disassembly and assembly position, the linear distance between the exhaust hole and the guiding surface gradually increases. With this structure, when the gas path main body 111 swings to the open position, since the distance between the exhaust hole and the guiding surface reaches the farthest, the exhaust valve head will be pushed outwards under the action of high-pressure carbon dioxide gas, so that the distance that the exhaust valve rod extends outwards reaches the maximum. At this time, the exhaust valve head no longer closes the exhaust passage, allowing the carbon dioxide gas in the water bottle to flow through the exhaust passage into the exhaust valve cavity and then be discharged through the exhaust hole. When the gas path main body 111 swings back to the working position, the guiding surface drives the exhaust valve rod to move inwards, so that the exhaust valve head blocks the exhaust passage.

[0051] In other embodiments, the exhaust valve can also be an electric valve body. A momentary switch cooperating with the electric valve body is provided inside the mounting head 11. When the gas path main body 111 swings to the disassembly and assembly position, the momentary switch is just pressed to open the electric valve body.

[0052] In this solution, since the protective container 20 can swing, in order to make the protective container 20 not easily swing randomly and thus have a certain stability, it is preferred that a base 12 is provided on the main body 10 and located directly below the mounting head 11. A swing groove 121 is provided on the base 12. A positioning groove 122 that is recessed downwards is provided at the end of the swing groove 121. The swing groove 121 slopes upwards towards the positioning groove 122. A first bead 24 and a first spring 241 located at the end of the first bead 24 are provided at the bottom of the protective container 20. During the process of the protective container 20 swinging from the open position to the initial position, the first bead 24 moves along the swing groove 121 and engages into the positioning groove 122. During the swinging process of the protective container 20, the first bead 24 will switch between the positioning groove 122 and the swing groove 121. A certain external force needs to be applied during the switching process to make the first bead 24 overcome the elastic force of the first spring 241 and then be pressed inwards, so that the protective container 20 has a certain stability during the swinging process. At the same time, since only one positioning groove 122 is provided at the end of the swing groove 121, when the protective container 20 swings to the open position, after only opening the door body 22 so that there is no longer any positional interference with the water bottle, the protective container 20 will automatically swing towards the initial position under the action of gravity.

[0053] For further optimization, it is preferred that a shock pad 25 is provided at the bottom of the protection container 20 above the first spring 241, so that the vibration is smaller during the swinging process of the protection container 20.

[0054] For further optimization, it is preferred that a damping structure is provided between the fixed housing 21 and the door body 22. The damping structure includes a damping gear 211 and an annular tooth groove 222 engaged with the damping gear 211. The damping gear 211 and the annular tooth groove 222 are respectively arranged on the fixed housing 21 and the door body 22. Through this structure, the opening and closing speed of the door body 22 is slowed down, so that a strong impact effect will not occur.

[0055] In this solution, during the swinging process of the protection container 20 and the gas path main body 111, their swinging axes may not coincide. In order to simplify the structure and optimize the swinging path at the same time, it is preferred that the swinging axis of the protection container 20 coincides with the swinging axis of the gas path main body 111. It is preferred that there are two pivot frames 112 on the left and right in the installation head 11. An inner side of the pivot frame 112 is provided with a pivot shaft 1121. An end of the pivot shaft 1121 is provided with a pivot hole 1122. Two ears 23 are provided at the top of the fixed housing 21. Rotation holes 231 sleeved on the two pivot shafts 1121 are respectively arranged on the two ears 23. Shaft rods 1111 inserted into the pivot holes 1122 are respectively arranged on two sides of the gas path main body 111. Through this structure, the pivot operation of the gas path main body 111 and the protection container 20 is synchronously completed through a set of pivot frames 112.

[0056] On this basis, it is preferred that an arc groove 113 is provided outside the gas path main body 111 in the installation head 11. A positioning bead hole 1131 is respectively arranged at two ends of the arc groove 113. A second bead and a second spring located inside the second bead are arranged on a side surface of the gas path main body 111. The second bead is located in the arc groove 113. During the swinging process of the gas path main body 111, the second bead is driven to switch in all the positioning bead holes 1131. Through the arc groove 113 and the positioning bead holes 1131 at two ends of the arc groove 113, a positioning and fixing effect is formed by the second bead when the gas path main body 111 is in the working position or the disassembly and assembly position. Only after applying a certain external force can the gas path main body 111 be switched between the working position and the disassembly and assembly position. Furthermore, it is convenient for the gas path main body 111 to be in the disassembly and assembly position for a long time to facilitate the disassembly and assembly of the water bottle, or to be in the working position for a long time, so that the water bottle will not shake when preparing sparkling water.

[0057] Through the above structure, the operation process of the whole sparkling water machine can be decomposed into the following states:

[0058] When installing the water bottle, the protection door is in the open position. The gas path main body 111 is fixed at the disassembly and assembly position through the engagement of the second bead. At this time, the water bottle is tilted and installed on the water bottle installation position of the gas path main body 111. Then the user manually swings the water bottle to make the water bottle enter the protection cavity, and the gas path main body 111 drives the water bottle to be fixed at the working position. The door body 22 is closed, and the bottom end of the fixing head 30 is engaged with the positioning notch 2211 at the top of the door body 22 to initially lock the door body 22. Then the preparation of sparkling water is carried out. During the preparation of sparkling water, the high-pressure carbon dioxide gas in the water bottle is transmitted to the pressure chamber 41 through the air guide channel 42, so that the pressure valve rod 44 on the pressure lock body 40 extends and inserts into the lock hole 2212 at the top of the door body 22, thereby locking the door body 22 for the second time. After the preparation of sparkling water is completed, the protection container 20 is swung from the initial position towards the open position, thereby unlocking the first lock of the fixing head 30 on the door body 22. At this time, the water bottle is synchronously driven and swung by the protection container 20, so that the gas path main body 111 is swung to the disassembly and assembly position. At this time, the exhaust valve rod extends to the maximum distance outside the exhaust hole under the action of air pressure, so that the exhaust valve head no longer blocks the exhaust channel, and the high-pressure carbon dioxide gas in the water bottle is discharged along the path of the exhaust channel - the exhaust valve cavity - the exhaust hole. When the high-pressure carbon dioxide gas in the water bottle is exhausted, since the pressure valve body 43 is no longer driven by the high-pressure carbon dioxide gas, at this time, the pressure valve rod 44 is reset under the action of the elastic reset member and no longer engages with the lock hole 2212, thereby unlocking the second lock of the door body 22. At this time, the door body 22 can be opened smoothly. After the door body 22 is opened, the protection container 20 automatically resets to the initial position under the action of gravity, so that the water bottle tilts out to the outside of the protection cavity, which is convenient for removing the water bottle.

[0059] Further optimization is as follows. When a user prepares sparkling water, it is often not the time to drink the sparkling water. If the high-pressure carbon dioxide gas in the water bottle is directly discharged after the preparation is completed, as time and temperature change, the carbon dioxide in the sparkling water in the water bottle will continuously precipitate, resulting in a lower carbonic acid concentration and a poorer taste when it is time to drink. If the air is not exhausted after the preparation is completed, but instead before drinking, it will cause the water bottle to always be in an overly pressurized state, which requires a higher quality for the water bottle. Over time, the lifespan of the water bottle will be significantly reduced. Preferably, a cylinder 1112 is provided on the outer surface of the gas path main body 111. A micro-hole exhaust cavity is provided inside the cylinder 1112. An exhaust micro-hole 1114 communicating with the micro-hole exhaust cavity is provided on the outer surface of the cylinder 1112. An elastic sealing sleeve 1113 covering the exhaust micro-hole 1114 is sleeved on the surface of the cylinder 1112. A pressure stop structure is provided on the gas path main body 111. The set air pressure value of the pressure stop structure is greater than the sealing air pressure of the elastic sealing sleeve 1113 on the exhaust micro-hole 1114. The pressure stop structure is a standard structure on the sparkling water machine. Its purpose is to automatically stop the air intake operation when the pressure in the water bottle reaches the preset specified value during the process of the sparkling water machine performing air intake operation on the water bottle to prepare sparkling water. It belongs to the prior art, and the structure will not be described in detail here.

[0060] With this solution, after the sparkling water is prepared, if it is necessary to drink it immediately, the carbon dioxide gas in the water bottle can be completely discharged directly through the exhaust valve, so that the water bottle can be removed after the user finishes the preparation. If the user does not need to drink directly after the preparation is completed, the active exhaust is not carried out through the exhaust valve first. The high-pressure carbon dioxide gas will push up the elastic sealing sleeve 1113 through the exhaust micro-hole 1114 and slowly discharge, finally making the carbon dioxide gas concentration in the water bottle in a relatively low state. During this process, since a certain carbon dioxide pressure is still maintained in the water bottle, the carbon dioxide in the sparkling water is not easily precipitated, thus ensuring the concentration of the sparkling water. When it is time to drink, the remaining residual pressure can be discharged through the exhaust valve.

[0061] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
