Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0039] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so as to describe the embodiments of the present application herein.

[0040] As shown in the structure diagram of a bubble water machine in one embodiment, a quick assembly structure is provided, which is applied to a bubble water machine. A limiting female part 410 is arranged on a gas cylinder 400 of the bubble water machine, and the quick assembly structure 500 comprises: Figures 1 to 5

[0041] ​The fixed support 510 is arranged on the bubble water machine, and the fixed support 510 is provided with an assembly cavity 501, and the limiting female part 410 is inserted into the assembly cavity 501.

[0042] The movable support 520 is arranged on the fixed support 510, and the movable support 520 is movable relative to the fixed support 510 and forms at least a first position and a second position.

[0043] The limiting male part 530 is arranged between the fixed support 510 and the movable support 520, and the movable support 520 can drive the limiting male part 530 to move at least partially in the assembly cavity 501, when the movable support 520 is located at the first position, the limiting male part 530 is buckled with the limiting female part 410, and when the movable support 520 is located at the second position, the limiting male part 530 is unbuckled with the limiting female part 410.

[0044] The quick assembly structure disclosed in the application includes a fixed support 510, a movable support 520 and a limiting male part 530, the fixed support 510 is arranged on the bubble water machine, and the fixed support 510 is provided with an assembly cavity 501, the movable support 520 is movably connected with the fixed support 510, and the movable support 520 is movable relative to the fixed support 510 and drives the limiting male part 530 to move at least partially in the assembly cavity 501, the limiting male part 530 is arranged between the fixed support 510 and the movable support 520, and the position state of the limiting male part 530 is changed when the movable support 520 moves, so that the limiting male part 530 is buckled or unbuckled with the limiting female part 410 on the gas cylinder 400, specifically, when the movable support 520 is located at the second position, the limiting male part 530 can be unbuckled with the limiting female part 410, at this time, the gas cylinder 400 can be assembled or disassembled, when the movable support 520 moves from the second position to the first position, the limiting male part 530 is buckled with the limiting female part 410, and then the gas cylinder 400 is fixed on the bubble water machine. The quick assembly structure 500 of the application can make the limiting male part 530 be buckled or unbuckled with the limiting female part 410 on the gas cylinder 400 quickly by the relative movement of the movable support 520, so that the gas cylinder 400 is quickly assembled, compared with the common threaded connection, the application can reduce the cumbersome disassembly of the gas cylinder 400, and provide convenience for the user.

[0045] The movable support 520 is movably arranged on the fixed support 510, and the movable support 520 is movable relative to the fixed support 510 and forms at least a first position and a second position.

[0046] 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.

[0047] 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.

[0048] like Figures 1 to 3 , Figure 5 As shown, 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.

[0049] 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.

[0050] 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.

[0051] like Figures 1 to 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first sliding groove 502 is flared, and the opening direction is towards the movable bracket 520.

[0052] 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.

[0053] 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.

[0054] As Figure 1 , Figure 2 and Figure 5 illustrated, in addition to the features of the above embodiments, the present embodiment is further defined as: the limiting male element 530 is a spherical structure, the limiting female element 410 is a plate structure, and is distributed on the lateral side of the gas cylinder 400.

[0055] The above quick assembly structure is further defined as: the limiting female element 410 is a plate structure, and the limiting male element 530 is a spherical structure, for example, the limiting male element 530 is a rigid sphere, when the limiting female element 410 is inserted into the assembly cavity 501, the limiting male element 530 at least partially extends into the assembly cavity 501, the limiting male element 530 abuts against the limiting female element 410 below, thereby fixing the gas cylinder 400 on the assembly structure, and when the movable bracket 520 is moved to the second position, the limiting male element 530 is circular, and the limiting male element 530 can easily slide along the groove wall of the first sliding groove 502 by its own gravity.

[0056] As Figure 3 illustrated, in addition to the features of the above embodiments, the present embodiment is further defined as: the minimum width of the first sliding groove 502 is less than the diameter of the limiting male element 530.

[0057] The above quick assembly structure is further defined as: the minimum width of the limiting groove is less than the diameter of the limiting male element 530, so that when the movable bracket 520 is pressed to move towards the assembly cavity 501, the limiting male element 530 will not fall into the assembly cavity 501, improving the rationality of the design, and ensuring the reliability of the structure.

[0058] As Figure 3 illustrated, in addition to the features of the above embodiments, the present embodiment is further defined as: the diameter of the limiting male element 530 is less than the width of the second gap 504.

[0059] The above quick assembly structure is further defined as: the diameter of the limiting male element 530 is less than the width of the second gap 504, so that when the movable bracket 520 is in the second position, even if the limiting male element 530 slides, it will not slide out of the second gap 504, and the reliability of the structure is ensured.

[0060] As Figure 3 and Figure 5 illustrated, in addition to the features of the above embodiments, the present embodiment is further defined as: the quick assembly structure 500 further comprises a return spring 540, the return spring 540 is connected with the fixed bracket 510 and the movable bracket 520 respectively, and the return spring 540 is used for resetting the movable bracket 520 from the second position to the first position.

[0061] The reset spring 540 can be used to reset the movable bracket 520 from the second position to the first position. Specifically, the reset spring 540 is connected with the fixed bracket 510 and the movable bracket 520, respectively. When the movable bracket 520 is forced to move from the first position to the second position, the reset 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 reset spring 540.

[0062] As shown in Figure 3 and Figure 5 In addition to the features of the above embodiments, the present embodiment is further limited in that the fixed bracket 510 is provided with a first through hole 505, the movable bracket 520 is provided with a limiting rod 521, the limiting rod 521 is opposite to the first through hole 505, and the reset spring 540 is sleeved on the limiting rod 521. When the movable bracket 520 moves relative to the fixed bracket 510, the limiting rod 521 moves relative to the first through hole 505.

[0063] The quick assembly structure is further limited in that the movable bracket 520 and the fixed bracket 510 are respectively provided with a limiting rod 521 and a first through hole 505. The limiting rod 521 and the first through hole 505 are oppositely arranged, so that when the movable bracket 520 reciprocally moves relative to the fixed bracket 510, the limiting rod 521 reciprocally moves relative to the first through hole 505, thereby ensuring the stability of the movement of the movable bracket 520 on the fixed bracket 510 and preventing the movable bracket 520 from deviating.

[0064] In one embodiment, as shown in Figures 1 to 3 The present embodiment provides a bubble water machine, which comprises a shell 100, a water storage bottle 200, an air inlet assembly 300, a gas cylinder 400, and the quick assembly structure 500 of any one of the above embodiments.

[0065] The air inlet assembly 300 is arranged on the shell 100, and an exhaust port of the air inlet assembly 300 is communicated with the water storage bottle 200 through a pipeline.

[0066] The quick assembly structure 500 is arranged on the shell 100 or the air inlet assembly 300, the gas cylinder 400 is connected with the quick assembly structure 500, and the gas cylinder 400 is communicated with the water storage bottle 200 through the air inlet assembly 300.

[0067] As shown in Figures 1 to 3As shown, in addition to the features of the above embodiments, this embodiment further defines: 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.

[0068] 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.

[0069] like Figure 3 and Figure 5 As shown, 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.

[0070] 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.

[0071] 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.

[0072] 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.
