[0002] Inflatable cushions are cushion products that can be used by inflating. They are easy to carry and have adjustable softness. They are practical in daily life and some specific scenarios. Inflatable cushions are made of various fabrics. For example, some products use elegant and clean fabrics, presenting beautiful wave shapes and beautiful appearance. Users can adjust the softness of the cushions by controlling the amount of air to achieve the best use effect and meet the needs of different people. Some inflatable cushions have double leak-proof functions to ensure that gas is not easy to leak during use and extend the use time. They can be used in sofas, back chairs, etc. to provide waist or back support for people during daily home activities such as resting and watching TV, and improve comfort. For example, put it on the sofa to make people lean more comfortably; put it on the chair to reduce the pressure on the waist when sitting for a long time.

The pump body of the present invention can be an external independent pump, or it can be built into items such as a mattress, an air cushion craft, a life buoy, etc.), turn on the inflation button or the exhaust button of the control button as needed. When inflating, turn on the inflation button, turn on the power supply, and the control module controls the second drive motor to operate, drive the fan gear to rotate so that the inflation stroke switch senses a signal that the valve plate is in place, and then stops the operation of the second drive motor, so that the air inlet passes through the intake flow channel and then through the three-way valve assembly to connect the air inlet end of the fan, and the air outlet end of the fan is synchronously connected to the inner chamber of the shell through the three-way valve assembly; the control module then controls the rotation of the first drive motor, and the first drive motor simultaneously drives the fan and the hydraulic valve assembly to operate synchronously, and the hydraulic valve group The impeller of the component rotates to push the hydraulic oil in the cylinder body, and the hydraulic oil gives the cylinder body a downward thrust, which overcomes the supporting force of the spring, and the cylinder body brings the valve stem to push the valve disc and the valve seat at the lower end of the shell to separate, so that the closed chamber in the shell and the lower end surface of the shell are connected to form an airway, that is, the chamber in the shell is connected to the inflatable space of the mattress, air cushion boat, life buoy and other items, and the fan is driven to rotate synchronously, and the fan connects the air inlet to the outside air to the inner chamber of the shell through the inlet airway, and then transmits it to the internal space of the mattress, air cushion boat, life buoy and other items through the airway between the valve disc at the lower end of the pump and the shell, so as to achieve rapid inflation. After the inflation is completed, the inflation button is turned off, the power supply is disconnected, the first drive motor stops, the impeller stops rotating, and the cylinder body is no longer subjected to the downward hydraulic thrust, then the spring supports the cylinder body to reset upward, so that the valve disc and the valve seat at the lower end of the shell are closed, effectively preventing the inflation space of the mattress, air cushion boat, life buoy and other items from being connected to the outside, resulting in air leakage; When exhaust is needed, the exhaust button is turned on, the power is turned on, and the control module controls the second drive motor to drive the fan gear to rotate so that the exhaust stroke switch senses the signal that the valve plate is in place, and then stops the operation of the second drive motor, so that the inner chamber of the shell is connected to the air inlet end of the fan through the three-way valve assembly, and the air outlet end of the fan is connected to the exhaust port at the upper end of the shell through the exhaust flow channel connected to the three-way valve assembly; the control module then controls the rotation of the first drive motor, and the first drive motor drives the fan and the hydraulic valve assembly to move synchronously at the same time, and the impeller of the hydraulic valve assembly rotates to push the hydraulic oil in the cylinder body, and the cylinder body is given a downward thrust through the hydraulic oil, and the thrust overcomes the supporting force of the spring. , the cylinder body carries the valve stem to push the valve disc and the valve seat at the lower end of the shell body to separate, so that the closed chamber in the shell body is connected to the lower end surface of the shell body to form an airway, that is, the chamber in the shell body is connected to the exhaust space of items such as mattresses, hovercrafts, lifebuoys, etc., and the airflow in the exhaust space flows into the inner chamber of the shell body, and the fan is driven to rotate synchronously. The fan actively discharges the gas in the inner chamber of the shell body to the outside world connected to the exhaust port at the upper end of the shell through the three-way valve assembly to achieve rapid exhaust. After the exhaust is completed, the exhaust button is closed, the power is disconnected, the first drive motor stops moving, the impeller stops rotating, and the cylinder body is no longer subjected to downward hydraulic thrust. The spring supports the cylinder body to reset upward, so that the valve disc and the valve seat at the lower end of the shell are closed.

[0042] For some occasions where negative pressure needs to be drawn, the operation is the same as the above exhaust operation, which can continuously discharge the airflow in the space to be exhausted, so that a negative pressure or low pressure state is formed in the space to be exhausted.

[0043] The inflation component of the present invention is cleverly designed, with a reasonable and compact structure, small size, and convenient to carry; the inflation and exhaust switching is achieved by switching the flow channel intake and exhaust, and the rotation direction of the fan does not need to be switched, the operation is stable, the impeller does not loosen or fall off, the noise is low, and the life of the fan is extended; the hydraulic valve component and the fan use the same drive motor, which saves costs and reduces installation space. The design is clever, and the fan and valve disc work synchronously, which is safe and reliable; the hydraulic valve component is designed to act on the hydraulic liquid through the rotation of the impeller, thereby pushing the cylinder body downward, and the cylinder body overcomes the spring force and carries the valve disc downward through the valve stem, and a gap is opened between the valve disc and the shell to form an air flow channel, the design is clever, the energy consumption is low, and there is no noise.
