Description

Technical Field

[0001] This invention relates to a gasified water production device, specifically to an air-filling structure for a gasified water production device. Background Technology

[0002] As people's living standards improve, their requirements for drinking water are also constantly increasing. Traditional drinking water equipment, such as water dispensers with heating and / or cooling functions and water purifiers with filtration functions, can no longer meet people's needs. Equipment that produces water mixed with gas, such as oxygen-enriched water machines, hydrogen-enriched water machines, and sparkling water (i.e., carbonated water) machines, is gradually entering people's lives.

[0003] The aforementioned water purification equipment mainly includes an aeration device and a liquid container. The aeration device directly pressurizes oxygen, hydrogen, or carbon dioxide into the liquid container to form oxygen-rich water, hydrogen-rich water, and sparkling water. Since the liquid stored inside the container is consumable, it is usually designed to be detachable. When aeration is required, the liquid container is first installed on the aerated water equipment. Then, the aeration nozzle is extended outwards to seal the liquid container. Finally, the aeration valve is opened to inflate the liquid container. After inflating, the aeration valve is closed to seal the gas cylinder, and then the aeration nozzle is retracted inwards to facilitate removal of the liquid container.

[0004] Because sealing or separating the liquid container and the inflation nozzle, and opening or closing the air valve require two steps, the inflation operation is not only labor-intensive, but also time-consuming because the sealing or separating of the liquid container and the inflation nozzle, and opening or closing the air valve must follow a strict sequence. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an inflation structure for a gas-filled water production device that has a smaller inflation workload and shorter inflation time, in view of the above-mentioned technical status.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an air-filling structure for a gasified water production device, used to fill a liquid container with an air inlet, comprising a base, a connector assembly, and a connecting assembly.

[0007] The connector assembly includes

[0008] A gas cylinder connector is provided on the base and is used to connect a gas cylinder. The gas cylinder connector has an outlet channel that can connect to the gas cylinder, and an outlet valve is provided in the outlet channel.

[0009] A switching element for opening or closing the air outlet valve;

[0010] Its features are:

[0011] The connection component includes

[0012] The housing is movably mounted on the base, and the interior of the housing has a cavity communicating with the air outlet channel.

[0013] The first spring causes the housing to always have an upward tendency to move;

[0014] An inflation nozzle is disposed in the cavity and can slide up and down. The lower end of the inflation nozzle extends out of the shell and can be used to connect to or disconnect from the air inlet of a liquid container located below the inflation nozzle.

[0015] The second spring ensures that the inflation nozzle always tends to move downwards;

[0016] A drive unit is rotatably mounted on the base, and the rotation of the drive unit can drive the switch to open the air valve and the housing to move downward in a synchronous action.

[0017] "Synchronization" simply means that the action of the switch opening the air outlet valve and the downward movement of the housing are both caused by the drive component. It does not limit the order of the action of the switch opening the air outlet valve and the downward movement of the housing, nor does it limit the duration of the action of the switch opening the air outlet valve and the duration of the downward movement of the housing. That is, the action of the switch opening the air outlet valve and the downward movement of the housing can start and end at the same time, or, only for a certain period of time, the action of the switch opening the air outlet valve and the downward movement of the housing can be carried out simultaneously, or, the housing finishes its downward movement before the switch starts its action of opening the air outlet valve.

[0018] To facilitate the up-and-down movement of the housing driven by the drive component, the drive component is constrained to the base in a manner that allows it to rotate around a horizontally extending axis of rotation. A first conversion structure is provided between the drive component and the housing. This first conversion structure can drive the housing downward under the rotation of the drive component, thereby allowing the inflation nozzle to be inserted into the air inlet of the liquid container.

[0019] To make it easier to open or close the gas outlet valve, the middle part of the switch is hinged to the inside of the gas cylinder connector and can swing up and down. The switch has a first end that can extend out of the gas cylinder connector. The connector assembly also includes a third spring that makes the switch always have a swinging tendency to close the gas outlet valve.

[0020] To facilitate the up-and-down swing of the drive switch, a second conversion structure is provided between the drive component and the switch. This second conversion structure can drive the switch to swing up or down under the rotation of the drive component. Because the third spring allows the switch to automatically reset, and the cooperation of the first and second conversion structures also ensures that the inflation nozzle only separates from the air inlet of the liquid container after the inflation valve is closed.

[0021] To simplify the first conversion structure, the first conversion structure includes an outwardly extending connecting portion provided on the circumferential surface of the drive member, and a connecting member hinged to the connecting portion, the connecting member being rotatably constrained to the housing.

[0022] To simplify the second conversion structure, the second conversion structure is a lever disposed on the driving member and capable of actuating the first end of the switching member. The lever and the connecting portion are arranged circumferentially on the driving member.

[0023] In a further design, the gas cylinder connector has a push rod that can slide up and down inside. The third spring is located inside the gas cylinder connector and makes the push rod always have an upward tendency, so that it can always hold the second end of the switch upward, and the lever can push the first end of the switch upward.

[0024] To facilitate the connection between the cavity of the shell and the water outlet channel, the connector is sleeved on the outside of the shell; to facilitate the assembly of the connector and the shell, the connector includes two mating sub-components, the upper end of each sub-component and one end of the connecting part are rotatably connected through a shaft hole and a rotating shaft; the lower end of each sub-component and the corresponding side of the shell are inserted into each other through a connecting post and a connecting hole.

[0025] To facilitate operation of the drive unit, a crank is also included, which has a horizontally extending pivot and a handle at one end of the pivot. The pivot is rotatably mounted on the base, and the drive unit is cylindrical and fitted onto the outside of the pivot.

[0026] To facilitate the installation of the connecting components, the base has mounting holes, and the housing can slide up and down through the mounting holes. The first spring is located on the second base and acts on the housing. The second spring is located in the cavity and extends the lower end of the inflation nozzle to below the mounting holes.

[0027] Compared with the prior art, the advantages of the present invention are as follows: the rotation of the driving component drives the synchronous action of the switching component to open the air outlet valve and the downward movement of the housing, so that the insertion of the inflation nozzle and the air inlet of the liquid container are synchronized with the opening of the air outlet valve by the switching component. The inflation of the liquid container can be completed in one operation, which reduces the workload and time of the inflation operation. Moreover, by setting the inflation nozzle to be able to move up and down, and through the cooperation of the second spring, as well as the reasonable setting of the stroke of the switching component and the stroke of the housing, the air outlet valve can be opened only after the inflation nozzle and the air inlet of the liquid container are inserted in place. It can also make the insertion of the inflation nozzle and the air inlet of the liquid container more secure, so that the inflation nozzle is not easily separated from the air inlet of the liquid container due to the air pressure rebound force generated when the liquid container is inflated, thus ensuring the sealing of the connection between the inflation nozzle and the liquid container.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] like Figures 1-10 The diagram shows the preferred embodiment of the present invention.

[0040] like Figure 1 and Figure 7 As shown, the inflation structure of the aerated water generator in this embodiment includes a base, a connector assembly, and a connecting assembly. This inflation structure is used to inflate a liquid container 9, which has an air inlet 91 and can be placed below the connecting assembly.

[0041] like Figure 6 and Figure 8 As shown, the base includes a first base 31 and a second base 32 adjacent to the first base 31 (see...). Figure 1 and Figure 7 The first base 31 has an upward-opening receiving cavity 311 in which the connector assembly is detachably disposed (see...). Figure 1 and Figure 7 Specifically, the connector assembly includes a gas cylinder connector 1, a switch 2, and a third spring 83. A stepped portion 312 is provided on the side wall of the receiving cavity 311, dividing the receiving cavity 311 into an upper chamber 311a and a lower chamber 311b. The gas cylinder connector 1 rests on the stepped portion 312 and is housed in the upper chamber 311a. The gas cylinder connector 1 can also be connected to a gas cylinder 11 via a threaded structure, and the gas cylinder 11 connected to the bottom of the gas cylinder connector 1 is housed in the lower chamber 311b. An exhaust channel 12 is provided inside the gas cylinder connector 1, and an exhaust valve 13 is located in the exhaust channel 12. The switch 2 is plate-shaped, and its middle part is hinged to the inside of the gas cylinder connector 1, allowing it to swing up and down. The switch 2 has a first end 2a and a second end 2b, and the first end 2a of the switch 2 can extend out of the upper chamber 311a. The gas cylinder connector 1 has a push rod 14 that can slide up and down inside. The third spring 83 is located inside the gas cylinder connector 1 and ensures that the push rod 14 always has an upward tendency, thus always pushing the second end 2b of the switch 2 upward. The exhaust valve 13 is located between the hinge position of the switch 2 and the second end 2b of the switch 2. The upward swing of the first end 2a of the switch 2 can open the exhaust valve 13, and the downward swing of the first end 2a of the switch 2 can close the exhaust valve 13.

[0042] like Figure 2 , Figure 3 and Figure 5 As shown, the connecting assembly includes a housing 41, an inflation nozzle 42, a first spring 81, a second spring 82, a drive component 6, and a crank handle 5. A mounting hole 321 is provided on the second base 32, and the housing 41 can slide up and down through the mounting hole 321. The second base 32 has a mounting groove 322 on each of the left and right sides of the mounting hole 321, and a positioning post 413 is provided on each of the left and right sides of the housing 41. There are two first springs 81, which are respectively inserted into the corresponding mounting grooves 322 and fitted onto the corresponding positioning posts 413, so that the housing 41 always has an upward tendency to move. The housing 41 has an internal cavity 411, and the air outlet end of the air outlet channel 12 has an air outlet nozzle. The housing 41 has an air inlet nozzle communicating with the internal cavity 411, and the air inlet nozzle and the air outlet nozzle are connected by a flexible hose. The inflation nozzle 42 is slidably disposed within the cavity 411, thereby communicating with the air outlet channel 12. The lower end of the inflation nozzle 42 extends beyond the exterior of the housing 41 and below the mounting hole 321. A second spring 82 is disposed within the cavity 411, and this second spring 82 ensures that the inflation nozzle 42 always has a downward tendency. When the housing 41 moves downward, the housing 41 can drive the inflation nozzle 42 downward until it is inserted into the air inlet 91 of the liquid container 9 (see...). Figure 1 When the housing 41 moves upward, it can drive the inflation nozzle 42 upward until it separates from the air inlet 91 of the liquid container 9 (see...). Figure 7 ).

[0043] like Figure 2 , Figure 5 and Figure 8 As shown, the crank 5 has a pivot 51 extending in the left-right direction and a handle 52 located at one end of the pivot 51. The pivot 51 is rotatably mounted on the second base 32. The drive member 6 is cylindrical and fitted outside the pivot 51, so that the drive member 6 can be rotated by rotating the handle 52. A first conversion structure is provided between the drive member 6 and the housing 41. The first conversion structure can drive the housing 41 to move downward under the rotation of the drive member 6, so that the inflation nozzle 42 can be inserted into the air inlet 91 of the liquid container 9. A second conversion structure is provided between the drive member 6 and the switch member 2. The second conversion structure can drive the switch member to swing upward under the rotation of the drive member 6, thereby opening the air outlet valve 13.

[0044] The first conversion structure includes a connecting portion 61 located on one circumferential side of the drive member 6, and a connecting member 7 hinged to the connecting portion 61. The connecting member 7 is rotatably constrained to the housing 41 (see...). Figure 2 The connector 7 is fitted over the housing 41, and allows the hose connecting the air outlet passage 12 to the housing 41 to pass through. The connector 7 includes two mating sub-components 71 (see...). Figure 2 Each sub-component 71 has a shaft hole 711 at its upper end (see...). Figure 10 The connecting part 61 has a rotating shaft part 611 on both sides of one end, and each rotating shaft part 611 is rotatably connected to the corresponding shaft hole 711 (see...). Figure 2 This facilitates the hinge connection between the connector 7 and the connecting part 61. Each sub-component 71 has a connecting post 712 at its lower end, and connecting holes 412 are respectively opened on both sides of the housing 41. Each connecting hole 412 is for insertion into the corresponding connecting post 712 (see...). Figure 5 This facilitates the constraint of the connector 7 on the housing 41.

[0045] like Figure 6 , Figure 8 and Figure 9 As shown, the second conversion structure is a lever 62 provided on the driving member 6 and capable of moving the first end 2a of the switch member 2 upward. The lever 62 and the connecting part 61 are arranged at intervals along the circumference of the driving member 6, and the lever 62 and the connecting part 61 are spaced apart in the length direction of the driving member 6.

[0046] The working principle of the air-filling structure of the aerated water production device in this embodiment is as follows:

[0047] During inflation, place the liquid container 9 below the second base 32, aligning the air inlet 91 of the liquid container 9 with the inflation nozzle 42. Press down the handle 52, causing the pivot 51 to rotate counterclockwise (viewed from the right), which in turn drives the drive 6 to rotate counterclockwise (viewed from the right), causing the connecting part 61 to swing downwards, which in turn drives the connecting part 7 to swing. This causes the housing 41 and the inflation nozzle 42 to move downwards simultaneously. At the same time, the lever 62 swings upwards to push the first end 2a of the switch 2 upwards. When the inflation nozzle 42 moves downwards to engage with the air inlet 91 of the liquid container 9, the switch 2 contacts the outlet valve 13. Subsequently, continue pressing down the handle 52. The inflation nozzle 42 no longer moves downwards, but the housing 41 continues to move downwards, creating relative movement between it and the inflation nozzle 42. The lever 62 continues to swing upwards, causing the switch 2 to press down the valve stem of the outlet valve 13 to open the outlet valve 13, thus connecting the gas cylinder 11 and the inflation nozzle 42 and completing the inflation of the liquid container 9.

[0048] After inflation is complete, release handle 52, causing housing 41 and inflation nozzle 42 to move upward and reset under the action of first spring 81 and second spring 82, thereby driving drive 6 and crank 5 to reset. At the same time, switch 2 is reset under the action of third spring 83, thereby closing air outlet valve 13 and separating inflation nozzle 42 from air inlet 91 of liquid container 9.

[0049] In this embodiment, the inflation structure of the aerated water generator uses the rotation of the drive component 6 to drive the switch component 2 to open the air outlet valve 13 and the housing 41 to move downwards in sync. This allows the insertion of the inflation nozzle 42 and the air inlet 91 of the liquid container 9 to occur simultaneously with the opening of the air outlet valve 13 by the switch component 2. Inflation can be completed in a single operation, reducing the workload and time required. Furthermore, by configuring the inflation nozzle 42 to move up and down, and through the coordinated action of the second spring 82, as well as the reasonable setting of the stroke of the switch component 2 and the housing 41, the inflation nozzle 42 and the liquid container 9 can be aligned vertically. After the air inlet 91 is inserted into place, the air outlet valve 13 can be opened. After the air outlet valve 13 is closed, the inflation nozzle 42 can be separated from the air inlet 91 of the liquid container 9. This also makes the insertion of the inflation nozzle 42 and the air inlet 91 of the liquid container 9 more secure, so that the inflation nozzle 42 is not easily separated from the air inlet 91 of the liquid container 9 due to the air pressure rebound force generated when the liquid container 9 is inflated, thus ensuring the sealing of the connection between the inflation nozzle 42 and the liquid container 9.
