[0033] As shown in Figures 1 to 5 The present application provides a specific embodiment of a gas charging and discharging integrated control device for controlling the gas charging and discharging of a gas charging object, which includes an outer cylinder 1 and an inner cylinder 2 operable to rotate within the outer cylinder 1, and the inner cylinder 2 has a gas flow passage 3 therein, and the two ends of the gas flow passage 3 are respectively provided with a first one-way valve 4 and a second one-way valve 5. In the present embodiment, the first one-way valve 4 and the second one-way valve 5 are preferably one-way air valves made of soft rubber, and have good elasticity and sealing performance.

[0034] The first one-way valve 4 is configured to allow the gas flow to be discharged from the gas charging object, but restricts the gas flow to be charged into the gas charging object. Specifically, when the gas pressure inside the gas charging object is greater than the external gas pressure, the first one-way valve 4 is pushed away to allow the gas flow to be discharged from the gas charging object; and when the external gas pressure is greater than the gas pressure inside the gas charging object, the first one-way valve 4 is tightly adhered to restrict the gas flow to be discharged from the gas charging object. The second one-way valve 5 is configured to restrict the gas flow to be discharged from the gas charging object, but allows the gas flow to be charged into the gas charging object. That is, when the external gas pressure is greater than the gas pressure inside the gas charging object, the second one-way valve 5 is pushed away to allow the gas flow to be charged into the gas charging object; and when the gas pressure inside the gas charging object is greater than the external gas pressure, the second one-way valve 5 is tightly adhered to restrict the gas flow to be discharged from the gas charging object.

[0035] By rotating the inner cylinder 2, the inner cylinder 2 can be switched between the inflation position 101 and the deflation position 102. A gas flow distribution space 10 is formed between the first one-way valve 4 and the second one-way valve 5, which is used to guide the gas flow into or out of the inflatable object when the inner cylinder 2 is in different positions.

[0036] When the inner cylinder 2 is in the inflation position 101, the gas flow distribution space 10 is communicated with the inside of the inflatable object through the inflation passage S1 passing through the inner cylinder 2 and the outer cylinder 1. Specifically, the first gas hole 6 on the side wall of the inner cylinder 2 is aligned with and penetrates through the third gas hole 8 on the outer cylinder 1, forming the inflation passage S1. At this time, the external gas flow can enter the gas flow distribution space 10 through the second one-way valve 5, and then fill into the inflatable object through the inflation passage S1. At the same time, since the deflation passage S2 is configured in a closed state at the inflation position 101, that is, the second gas hole 7 on the side wall of the inner cylinder 2 is misaligned with the fourth gas hole 9 on the outer cylinder 1, so there is no gas flow leaked out through the deflation passage S2 during inflation.

[0037] When the inner cylinder 2 is in the deflation position 102, the gas flow distribution space 10 is communicated with the outside through the deflation passage S2 passing through the inner cylinder 2 and the outer cylinder 1. Specifically, the second gas hole 7 on the side wall of the inner cylinder 2 is aligned with and penetrates through the fourth gas hole 9 on the outer cylinder 1, forming the deflation passage S2. At this time, the gas flow inside the inflatable object can enter the gas flow distribution space 10 through the first one-way valve 4, and then be discharged to the outside through the deflation passage S2. At the same time, since the inflation passage S1 is configured in a closed state at the deflation position 102, that is, the first gas hole 6 on the side wall of the inner cylinder 2 is misaligned with the third gas hole 8 on the outer cylinder 1, so there is no external gas flow entering the inflatable object through the inflation passage S1 during deflation.

[0038] Further, in order to improve the efficiency of inflation and deflation, the gas flow distribution space 10 is configured to pass through the gas flow in opposite directions when the inner cylinder 2 is in the inflation position 101 and the deflation position 102. In this way, during inflation, the gas flow in the gas flow distribution space 10 can smoothly enter the inflatable object through the inflation passage S1; during deflation, the gas flow in the gas flow distribution space 10 can also smoothly be discharged to the outside through the deflation passage S2.

[0039] In addition, the inflation channel S1 and the deflation channel S2 are arranged in a staggered manner in the horizontal direction to avoid air exchange between the inflation channel S1 and the deflation channel S2 during inflation and deflation, thereby affecting the inflation or deflation effect. Meanwhile, the inner cylinder 2 and the outer cylinder 1 also have a sealing member for gas isolation between the inflation channel S1 and the deflation channel S2, to avoid air leakage between the inflation channel S1 and the deflation channel S2, thereby ensuring smooth inflation and deflation and maximizing gas flow. In this embodiment, the sealing member includes a groove 11 formed in the outer side wall of the inner cylinder 2 and a sealing rubber ring 12 located in the groove 11. When the inner cylinder 2 rotates in the outer cylinder 1, the sealing rubber ring 12 can tightly fit the inner wall of the outer cylinder 1, thereby achieving good sealing effect.

[0040] In order to limit the rotation range of the inner cylinder 2 and ensure that the inflation channel S1 and the deflation channel S2 can be accurately connected when needed, the inflation and deflation integrated control device further includes a rotation limiting structure. The rotation limiting structure is configured to limit the rotation of the inner cylinder 2 within the range of the inflation position 101 and the deflation position 102. In this embodiment, the rotation limiting structure includes a sliding block 13 provided on the outer side wall of the inner cylinder 2 and a limiting sliding groove 14 at the top end of the outer cylinder 1 for limiting the rotation of the sliding block 13. When the inner cylinder 2 rotates, the sliding block 13 will slide in the limiting sliding groove 14, and when the sliding block 13 slides to the end of the limiting sliding groove 14, the inner cylinder 2 cannot continue to rotate, thereby ensuring the accurate connection of the inflation channel S1 and the deflation channel S2.

[0041] Further, in order to facilitate user operation and intuitively understand the rotation position of the inner cylinder 2, the inflation and deflation integrated control device further includes a sealing cover 16 arranged outside the outer cylinder 1. The sealing cover 16 is arranged between the inflation channel S1 and the deflation channel S2, and has an indication mark 15 for controlling the rotation stroke of the inner cylinder 2. The indication mark 15 corresponds to the sliding block 13 on the outer side wall of the inner cylinder 2 and the limiting sliding groove 14 at the top end of the outer cylinder 1. When the user rotates the inner cylinder 2, the rotation of the inner cylinder 2 can be judged by observing the relative position of the indication mark 15 and the limiting sliding groove 14, thereby ensuring the accuracy of the inflation or deflation operation.

[0042] In this embodiment, the sealing cover 16 also includes a first end and a second end, and the first end and the second end have a partition portion combined with the outer cylinder 1. The partition portion is in interference fit with the outer cylinder 1 to ensure that the air pressure inside the inflation and deflation integrated control device does not leak, thereby maximizing the gas flow. Meanwhile, the interference fit can also improve the overall structural strength and stability of the inflation and deflation integrated control device.

[0043] In summary, the gas filling and discharging integrated control device provided by the utility model controls the one-way flow of gas during gas filling and discharging by setting two one-way valves, and realizes the conduction between different airflow distribution spaces and the gas filling channel and the gas discharging channel by rotating the inner cylinder. This structure enables the airflow to only pass through the airflow distribution space during gas filling and discharging and not to contact the outside, thereby enhancing the sealing property and improving the gas filling and discharging efficiency. Meanwhile, the gas filling channel and the gas discharging channel are arranged in a staggered manner in the horizontal direction, and a sealing member is arranged between the inner cylinder and the outer cylinder, thereby further improving the gas filling and discharging efficiency. In addition, the rotation limiting structure and the indication mark are arranged, so that the user can conveniently and accurately operate the gas filling and discharging integrated control device.

[0044] The embodiment provides a specific gas filling and discharging integrated control device, which has the same structure as that described in the above specific embodiment. The gas filling and discharging integrated control device is used for controlling the gas filling and discharging of an air bed.

[0045] In use, the user first connects the gas filling and discharging integrated control device to the air nozzle of the air bed. Then, the user rotates the sealing cover 16 on the outer cylinder 1 to drive the inner cylinder 2 to rotate. When gas filling is needed, the user rotates the inner cylinder 2 to the gas filling position 101, and at this time, the first air hole 6 is aligned with the third air hole 8 and is in conduction to form a gas filling channel S1. The outside airflow enters the second one-way valve 5 through the gas filling pump (not shown) connected to the gas filling and discharging integrated control device, and then enters the air bed through the airflow distribution space 10 and the gas filling channel S1. At the same time, since the gas discharging channel S2 is closed at the gas filling position 101, no airflow can leak out through the gas discharging channel S2.

[0046] When gas discharging is needed, the user rotates the inner cylinder 2 to the gas discharging position 102, and at this time, the second air hole 7 is aligned with the fourth air hole 9 and is in conduction to form a gas discharging channel S2. The airflow in the air bed enters the airflow distribution space 10 through the first one-way valve 4, and then is discharged to the outside through the gas discharging channel S2. At the same time, since the gas filling channel S1 is closed at the gas discharging position 102, no outside airflow can enter the air bed through the gas filling channel S1.

[0047] The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is subject to the scope defined by the claims. Some improvements and decorations made by the person skilled in the art without departing from the spirit and range of the utility model should also be regarded as the protection scope of the utility model.
