Description

A quick assembly structure and a bubble water machine

[0001] This application claims priority to Chinese Patent Application No. 202520704901.2, filed on April 14, 2025, entitled "A Quick Assembly Structure and Aerated Water Machine", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of sparkling water machine technology, and in particular to a quick assembly structure and a sparkling water machine. Background Technology

[0003] The main function of a sparkling water machine is to convert ordinary drinking water into carbonated water (sparkling water) containing carbon dioxide. Its core function is to create bubbles in the water by injecting carbon dioxide gas. Currently, most existing sparkling water machines use threaded connections for gas cylinder assembly and disassembly. This assembly method has the following problems: First, thread alignment is difficult, leading to excessive installation time or damage to the interface. Second, the operation is cumbersome, potentially requiring multiple rotations, which is time-consuming and labor-intensive. Third, there are sealing issues; if the threaded connection is not tightened properly, it can cause gas leakage, affecting the carbonation effect. Utility Model Content

[0004] Therefore, it is necessary to provide a quick assembly structure and a sparkling water machine to address the aforementioned problems in the disassembly and assembly process of gas cylinders in existing sparkling water machines.

[0005] In a first aspect, this application provides a quick assembly structure applied to a sparkling water machine, wherein a limiting female component is provided on the gas cylinder of the sparkling water machine, and the quick assembly structure includes:

[0006] A fixed bracket is provided on the sparkling water machine, and the fixed bracket has an assembly cavity in which the limiting female part is inserted.

[0007] A movable support is disposed on the fixed support, and the movable support is movable relative to the fixed support, forming at least a first position and a second position;

[0008] A limiting male component is provided between the fixed bracket and the movable bracket. The movable bracket can drive the limiting male component to move at least partially within the assembly cavity. When the movable bracket is in the first position, the limiting male component is engaged with the limiting female component. When the movable bracket is in the second position, the limiting male component is disengaged from the limiting female component.

[0009] The quick assembly structure disclosed in this application includes a fixed bracket, a movable bracket, and a limiting member. The fixed bracket is installed on the sparkling water machine and has an assembly cavity. The movable bracket is movably connected to the fixed bracket and can move relative to the fixed bracket, driving the limiting member to move at least partially within the assembly cavity. The limiting member is positioned between the fixed bracket and the movable bracket. When the movable bracket moves, it changes the position of the limiting member, thereby enabling the limiting member to engage or disengage with a limiting female component on the gas cylinder. Specifically, when the movable bracket is in the second position, the limiting member can disengage from the limiting female component, allowing the gas cylinder to be assembled or disassembled. When the movable bracket moves from the second position to the first position, the limiting member engages with the limiting female component, thus fixing the gas cylinder on the sparkling water machine. The quick assembly structure of this application allows the male limiting component to quickly engage or disengage with the female limiting component on the gas cylinder through relative movement of the movable bracket, thereby achieving quick assembly of the gas cylinder. Compared with common threaded connections, this application can reduce the cumbersome process of disassembling and assembling gas cylinders and provide convenience for users.

[0010] In one embodiment, the fixed bracket has a first sliding groove communicating with the assembly cavity, the limiting member is movably disposed within the first sliding groove, the movable bracket is sleeved around the fixed bracket, and the movable bracket and the fixed bracket form at least a first gap and a second gap, the width of the first gap being smaller than the width of the second gap; when the movable bracket is in a first position, the first gap is opposite to the first sliding groove, and the movable bracket presses the limiting member to slide towards the assembly cavity; when the movable bracket is in a second position, the second gap is opposite to the first sliding groove, and the limiting member can slide away from the assembly cavity.

[0011] The quick assembly structure in the above embodiments further defines at least two gaps, a first gap and a second gap, of different widths, between the movable bracket and the fixed bracket. A limiting male component is movably mounted on a first sliding groove on the fixed bracket. When the movable bracket is in the first position, the limiting male component is pressed by the inner wall of the movable bracket and moves toward the assembly cavity, so that the limiting male component and the limiting female component are engaged. When the movable bracket is moved to the second position, the limiting male component can move away from the assembly cavity, so that the limiting male component and the limiting female component are disengaged. This facilitates the quick assembly of the gas cylinder and has a simple structure.

[0012] In one embodiment, the first sliding groove is funnel-shaped and the opening faces the movable bracket.

[0013] The quick assembly structure in the above embodiment further defines the first sliding groove as a funnel shape. The opening of the first sliding groove faces the movable bracket, so that when the movable bracket is in the second position, the first sliding groove is opposite to the lower part of the inner wall of the movable bracket. The limiting male part can slide along the groove wall of the first sliding groove by its own gravity, so that the limiting male part is separated from the limiting female part, simplifying the operation steps.

[0014] In one embodiment, the male limiting component is a spherical structure, and the female limiting component is a plate-like structure, and they are distributed around the periphery of the gas cylinder.

[0015] The quick assembly structure in the above embodiments further defines the limiting female part as a plate-shaped structure and the limiting male part as a spherical structure. For example, the limiting male part is a rigid sphere. When the limiting female part is inserted into the assembly cavity, the limiting male part extends into the assembly cavity at least partially. The limiting male part abuts against the lower part of the limiting female part, thereby fixing the gas cylinder on the assembly structure. When the movable bracket is moved to the second position, because the limiting male part is circular, the limiting male part can easily slide along the groove wall of the first sliding groove by its own gravity.

[0016] In one embodiment, the minimum width of the first sliding groove is less than the diameter of the limiting member.

[0017] The quick assembly structure in the above embodiments further limits the minimum width of the limiting groove to be less than the diameter of the limiting male part, so that when the movable bracket moves towards the assembly cavity by squeezing the limiting male part, the limiting male part will not fall into the assembly cavity entirely, thereby improving the rationality of the design and ensuring the reliability of the structure.

[0018] In one embodiment, the diameter of the limiting member is smaller than the width of the second gap.

[0019] The quick assembly structure in the above embodiments further limits the diameter of the limiting male to be smaller than the width of the second gap, so that even if the limiting male slides when the movable bracket is in the second position, it will not slide out of the second gap, and ensures the reliability of the structure.

[0020] In one embodiment, the quick assembly structure further includes a return spring, which is connected to the fixed bracket and the movable bracket respectively, and the return spring is used to reset the movable bracket from the second position to the first position.

[0021] In one embodiment, the fixed bracket has a first through hole, the movable bracket has a limit rod, the limit rod is positioned opposite to the first through hole, the return spring is sleeved on the limit rod, and when the movable bracket moves relative to the fixed bracket, the limit rod moves relative to the first through hole.

[0022] The quick assembly structure in the above embodiments further defines that the movable bracket and the fixed bracket are respectively provided with a limit rod and a first through hole. By setting the positions of the limit rod and the first through hole relative to each other, when the movable bracket moves back and forth relative to the fixed bracket, the limit rod moves back and forth relative to the first through hole, ensuring the stability of the movable bracket's movement on the fixed bracket and preventing it from easily deviating.

[0023] Secondly, this application provides a sparkling water machine, including a shell, a water storage bottle, an air inlet assembly, a gas cylinder, and a quick assembly structure as described in any of the above.

[0024] The air intake assembly is mounted on the outer casing, and the exhaust port of the air intake assembly is connected to the water storage bottle via a pipe.

[0025] The quick assembly structure is disposed on the outer shell or the air intake assembly, the gas cylinder is connected to the quick assembly structure, and the gas cylinder is connected to the water storage bottle through the air intake assembly.

[0026] In one embodiment, the air intake assembly includes an air intake valve, a push rod, and a control lever. The air intake valve has an air guide chamber and a second sliding groove communicating with the air guide chamber. The push rod is slidably disposed in the second sliding groove. The control lever is rotatably disposed on the housing and is connected to the push rod. The fixed bracket has a second through hole communicating with the assembly cavity. The gas cylinder at least partially passes through the second through hole and extends into the air guide chamber.

[0027] The quick assembly structure in the above embodiments further limits the control lever to rotate relative to the outer shell. When an external force is applied to the control lever, the push rod is squeezed by the control lever and moves toward the mechanical switch of the gas cylinder, and presses and triggers the mechanical switch of the gas cylinder. The gas cylinder releases carbon dioxide gas into the gas guide chamber, thereby filling the water storage bottle.

[0028] In one embodiment, a sealing ring is provided in the air guiding cavity, and the sealing ring is sandwiched between the air inlet valve and the gas cylinder. The sealing ring is used to seal the gap between the gas cylinder and the air guiding cavity.

[0029] The quick assembly structure in the above embodiments further specifies that a sealing ring is provided between the air inlet valve and the gas cylinder to prevent gas leakage during the process of the gas cylinder releasing carbon dioxide gas into the water storage bottle.

[0039] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0040] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.

[0041] As shown in Figures 1 to 5, this embodiment provides a quick assembly structure applied to a sparkling water machine. A limiting female part 410 is provided on the sparkling water machine's gas cylinder 400. The quick assembly structure 500 includes:

[0042] A fixed bracket 510 is installed on the sparkling water machine. The fixed bracket 510 has an assembly cavity 501, and a limiting female part 410 is inserted into the assembly cavity 501.

[0043] The movable support 520 is mounted on the fixed support 510. The movable support 520 can move relative to the fixed support 510 and can form at least a first position and a second position.

[0044] A limiting male component 530 is provided between the fixed bracket 510 and the movable bracket 520. The movable bracket 520 can drive the limiting male component 530 to move at least partially within the assembly cavity 501. When the movable bracket 520 is in the first position, the limiting male component 530 is engaged with the limiting female component 410. When the movable bracket 520 is in the second position, the limiting male component 530 is disengaged from the limiting female component 410.

[0045] The quick assembly structure disclosed in this application includes a fixed bracket 510, a movable bracket 520, and a limiting member 530. The fixed bracket 510 is mounted on the sparkling water machine and has an assembly cavity 501. The movable bracket 520 is movably connected to the fixed bracket 510 and can move relative to the fixed bracket 510, driving the limiting member 530 to move at least partially within the assembly cavity 501. The limiting member 530 is positioned between the fixed bracket 510 and the movable bracket 520. When the movable bracket 520 moves, it changes the position of the limiting male component 530, thereby enabling the limiting male component 530 to engage or disengage with the limiting female component 410 on the gas cylinder 400. Specifically, when the movable bracket 520 is in the second position, the limiting male component 530 can disengage from the limiting female component 410, allowing the gas cylinder 400 to be assembled or disassembled. When the movable bracket 520 moves from the second position to the first position, the limiting male component 530 engages with the limiting female component 410, thus fixing the gas cylinder 400 onto the sparkling water machine. The quick assembly structure 500 of this application, through the relative movement of the movable bracket 520, enables the limiting male component 530 to quickly engage or disengage with the limiting female component 410 on the gas cylinder 400, thereby achieving rapid assembly of the gas cylinder 400. Compared to common threaded connections, this application can reduce the cumbersome process of assembling and disassembling the gas cylinder 400, providing convenience for users.

[0046] The movable bracket 520 can be moved relative to the fixed bracket 510 by manual pressure. Specifically, the movable bracket 520 is sleeved on the periphery of the fixed bracket 510, and can be moved up and down along the vertical direction of the fixed bracket 510 by manual pressure, forming at least a first position and a second position. In other embodiments, the movable bracket 520 is equipped with a handle-like structure to facilitate user control of its movement relative to the fixed bracket 510.

[0047] The male limiting component 530 can engage or disengage with the female limiting component 410 on the gas cylinder 400. Since the male limiting component 530 is located between the movable support 520 and the fixed support 510, when the movable support 520 moves relative to the fixed support 510, the position of the male limiting component 530 changes, causing it to engage or disengage with the female limiting component 410. Specifically, when the movable support 520 is in the first position, the male limiting component 530 is in the third position, and it engages with the female limiting component 410. When the movable support 520 moves from the first position to the second position, it can move the male limiting component 530 from the third position to the fourth position, or, under its own weight, the male limiting component 530 moves from the third position to the fourth position, disengaging from the female limiting component 410.

[0048] It should be noted that the fastening structure between the male limiting component 530 and the female limiting component 410 can be one or a combination of cantilever buckles, ring buckles, ball buckles, hook buckles, and wedge buckles.

[0049] As shown in Figures 1 to 3 and Figure 5, in addition to the features of the above embodiments, this embodiment further specifies that: the fixed bracket 510 has a first sliding groove 502 communicating with the assembly cavity 501, the limiting member 530 is movably disposed in the first sliding groove 502, the movable bracket 520 is sleeved on the periphery of the fixed bracket 510, and the movable bracket 520 and the fixed bracket 510 form at least a first gap 503 and a second gap 504, the width of the first gap 503 being smaller than the width of the second gap 504; when the movable bracket 520 is in the first position, the first gap 503 is opposite to the first sliding groove 502, and the movable bracket 520 presses the limiting member 530 to slide toward the assembly cavity 501; when the movable bracket 520 is in the second position, the second gap 504 is opposite to the first sliding groove 502, and the limiting member 530 can slide away from the assembly cavity 501.

[0050] The aforementioned quick assembly structure further defines that the movable bracket 520 and the fixed bracket 510 form at least two first gaps 503 and second gaps 504 of different widths. The limiting male part 530 is movably set on the first sliding groove 502 on the fixed bracket 510. When the movable bracket 520 is in the first position, the limiting male part 530 is pressed by the inner wall of the movable bracket 520 and moves toward the assembly cavity 501, so that the limiting male part 530 and the limiting female part 410 are engaged. When the movable bracket 520 is moved to the second position, the limiting male part 530 can move away from the assembly cavity 501, so that the limiting male part 530 and the limiting female part 410 are disengaged, which facilitates the quick assembly of the gas cylinder 400 and has a simple structure.

[0051] Both the fixed support 510 and the movable support 520 can be annular tubular shell structures, with the movable support 520 distributed around the fixed support 510, creating a gap between the inner wall of the movable support 520 and the outer wall of the fixed support 510. The inner diameters of the movable supports 520 are not entirely uniform, meaning the inner wall of the movable support 520 has height variations. The distance between the higher part of the inner wall variation of the movable support 520 and the outer wall of the fixed support 510 is the first gap 503, and the distance between the lower part of the inner wall variation of the movable support 520 and the outer wall of the fixed support 510 is the second gap 504. The width of the first gap 503 is smaller than the width of the second gap 504. When the movable bracket 520 is in the first position, the higher part of the inner wall of the movable bracket 520 is opposite to the first sliding groove 502. The movable bracket 520 presses the limiting male part 530 to move towards the assembly cavity 501 and engages with the limiting female part 410. When the movable bracket 520 moves to the second position, the lower part of the inner wall of the movable bracket 520 is opposite to the first sliding groove 502. The movable bracket 520 can drive the limiting male part 530 to move from the third position to the fourth position, or under the action of gravity, the limiting male part 530 moves from the third position to the fourth position by itself, and the limiting male part 530 and the limiting female part 410 disengage.

[0052] As shown in Figures 1 to 3, in addition to the features of the above embodiments, this embodiment further specifies that: the first sliding groove 502 is in the shape of a trumpet, and the opening direction is towards the movable bracket 520.

[0053] The aforementioned quick assembly structure further defines the first sliding groove 502 as a funnel shape, with the opening of the first sliding groove 502 facing the movable bracket 520. When the movable bracket 520 is in the second position, the first sliding groove 502 is opposite to the lower part of the inner wall of the movable bracket 520. The limiting male part 530 can slide along the groove wall of the first sliding groove 502 by its own gravity, so that the limiting male part 530 is disengaged from the limiting female part 410, simplifying the operation steps.

[0054] The first sliding groove 502 can be a groove structure with openings at both ends, and the first sliding groove 502 is flared. Specifically, the opening width of the first sliding groove 502 is the smallest at the end closest to the assembly cavity 501, and the opening width of the first sliding groove 502 gradually increases in the direction away from the assembly cavity 501. Based on the fact that the limiting male part 530 is movably disposed in the first sliding groove 502, when the lower part of the inner wall of the movable bracket 520 is opposite to the first sliding groove 502, the limiting male part 530 can slide down along the side wall of the first sliding groove 502 under its own gravity, that is, the limiting male part 530 slides from the third position to the fourth position, thereby causing the limiting male part 530 to disengage from the limiting female part 410.

[0055] As shown in Figures 1, 2 and 5, in addition to the features of the above embodiments, this embodiment further specifies that: the limiting male part 530 is a spherical structure, the limiting female part 410 is a plate-like structure, and they are distributed around the gas cylinder 400.

[0056] The aforementioned quick assembly structure further defines the limiting female part 410 as a plate-shaped structure and the limiting male part 530 as a spherical structure. For example, the limiting male part 530 is a rigid sphere. When the limiting female part 410 is inserted into the assembly cavity 501, the limiting male part 530 extends at least partially into the assembly cavity 501. The limiting male part 530 abuts against the lower part of the limiting female part 410, thereby fixing the gas cylinder 400 on the assembly structure. When the movable bracket 520 is moved to the second position, because the limiting male part 530 is circular, the limiting male part 530 can easily slide along the groove wall of the first sliding groove 502 by its own gravity.

[0057] As shown in Figure 3, in addition to the features of the above embodiments, this embodiment further specifies that the minimum width of the first sliding groove 502 is less than the diameter of the limiting member 530.

[0058] The aforementioned quick assembly structure further limits the minimum width of the limiting groove to be less than the diameter of the limiting male part 530, so that when the movable bracket 520 moves the limiting male part 530 toward the assembly cavity 501, the limiting male part 530 will not fall entirely into the assembly cavity 501, thus improving the rationality of the design and ensuring the reliability of the structure.

[0059] As shown in Figure 3, in addition to the features of the above embodiments, this embodiment further specifies that the diameter of the limiting male part 530 is smaller than the width of the second gap 504.

[0060] The aforementioned quick assembly structure further limits the diameter of the limiting male part 530 to be smaller than the width of the second gap 504, so that even if the limiting male part 530 slides when the movable bracket 520 is in the second position, it will not slide out of the second gap 504, and ensures the reliability of the structure.

[0061] As shown in Figures 3 and 5, in addition to the features of the above embodiments, this embodiment further specifies that: the quick assembly structure 500 also includes a return spring 540, which is connected to the fixed bracket 510 and the movable bracket 520 respectively, and the return spring 540 is used to reset the movable bracket 520 from the second position to the first position.

[0062] The return spring 540 is used to reset the movable bracket 520 from the second position to the first position. Specifically, the return spring 540 is connected to the fixed bracket 510 and the movable bracket 520 respectively. When the movable bracket 520 is moved from the first position to the second position by force, the return spring 540 is compressed. When the external force on the movable bracket 520 is removed, the movable bracket 520 is driven to move from the second position to the first position under the action of the return spring 540.

[0063] As shown in Figures 3 and 5, in addition to the features of the above embodiments, this embodiment further specifies that: a first through hole 505 is provided on the fixed bracket 510, a limit rod 521 is provided on the movable bracket 520, the limit rod 521 is positioned opposite to the first through hole 505, a reset spring 540 is sleeved on the limit rod 521, and when the movable bracket 520 moves relative to the fixed bracket 510, the limit rod 521 moves relative to the first through hole 505.

[0064] The aforementioned quick assembly structure further defines the limit rod 521 and the first through hole 505 respectively on the movable bracket 520 and the fixed bracket 510. By setting the limit rod 521 and the first through hole 505 relative to each other, when the movable bracket 520 moves back and forth relative to the fixed bracket 510, the limit rod 521 moves back and forth relative to the first through hole 505, ensuring the stability of the movable bracket 520's movement on the fixed bracket 510 and preventing it from deviating.

[0065] In one embodiment, as shown in Figures 1 to 3, this embodiment provides a sparkling water machine, including a housing 100, a water storage bottle 200, an air inlet assembly 300, a gas cylinder 400, and a quick assembly structure 500 according to any one of claims 1-7.

[0066] The air intake assembly 300 is mounted on the housing 100, and the exhaust port of the air intake assembly 300 is connected to the water storage bottle 200 through a pipe.

[0067] The quick assembly structure 500 is mounted on the outer casing 100 or the air intake assembly 300. The gas cylinder 400 is connected to the quick assembly structure 500 and is connected to the water storage bottle 200 through the air intake assembly 300.

[0068] As shown in Figures 1 to 3, in addition to the features of the above embodiments, this embodiment further specifies that: the air intake assembly 300 includes an air intake valve 310, a push rod 320 and a control lever 330. The air intake valve 310 has an air guide chamber 301 and a second sliding groove 302 communicating with the air guide chamber 301. The push rod 320 is slidably disposed in the second sliding groove 302. The control lever 330 is rotatably disposed on the housing 100 and is connected to the push rod 320. The fixed bracket 510 has a second through hole 506 communicating with the assembly cavity 501. The gas cylinder 400 at least partially passes through the second through hole 506 and extends into the air guide chamber 301.

[0069] The quick assembly structure 500 in the above embodiment further limits the control lever 330 to be rotatable relative to the housing 100. When an external force is applied to the control lever 330, the push rod 320 is squeezed by the control lever 330 and moves toward the mechanical switch of the gas cylinder 400, and presses and triggers the mechanical switch of the gas cylinder 400. The gas cylinder 400 releases carbon dioxide gas into the gas guide chamber 301, thereby filling the water storage bottle 200.

[0070] As shown in Figures 3 and 5, in addition to the features of the above embodiments, this embodiment further specifies that: a sealing ring 550 is provided in the air guiding cavity 301, the sealing ring 550 is sandwiched between the air inlet valve 310 and the gas cylinder 400, and the sealing ring 550 is used to seal the gap between the gas cylinder 400 and the air guiding cavity 301.

[0071] The quick assembly structure 500 in the above embodiment further specifies that a sealing ring 550 is provided between the air inlet valve 310 and the gas cylinder 400 to prevent gas leakage during the process of the gas cylinder 400 releasing carbon dioxide gas into the water storage bottle 200.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
