An inflatable product, comprising: a side wall defining an inflation cell; a shell located on the side wall and extending into the inflation cell, the shell defining an internal chamber and an air valve, the air valve being in fluid communication with the internal chamber and the inflation cell; and an air pump including an air inlet and an air outlet, the air pump being located at least partially within the internal chamber; wherein the air pump is moveable within the internal chamber between a first position, a second position, and a neutral position; when the air pump is in the first position, the air inlet is connected to the air valve; when the air pump is in the second position, the air outlet is connected to the air valve; and when the air pump is in the neutral position, neither the air inlet nor the air outlet is connected to the air valve, wherein the shell includes an upper cover that defines an opening, and the air pump includes a knob switch that extends through the opening, and wherein the air pump further comprises: a pump body; and a driving assembly located inside the pump body; wherein the knob switch extends from the pump body and is moveable in the opening along a path causing the pump body to also move along the path; and wherein the knob switch and the pump body are moveable along a transverse direction that is transverse to the path to selectively connect the air outlet to the air valve in the first position or to connect the air inlet to the air valve in the second position, depending on the positioning of the knob switch and pump body along the path, characterized in that the opening is bounded by at least a first segment and a second segment, the knob switch being movable along the path between the first segment and the second segment; wherein the shell further comprises a limit structure to retain the knob switch and pump body in the first position or the second position and prevent movement of the knob switch and the pump body along the transverse direction; wherein when the knob switch is coupled to the limit structure, the limit structure retains the knob switch and pump body in one of the first position or the second position. the air pump is moveable within the internal chamber between a first position, a second position, and a neutral position; when the air pump is in the first position, the air inlet is connected to the air valve; when the air pump is in the second position, the air outlet is connected to the air valve; and when the air pump is in the neutral position, neither the air inlet nor the air outlet is connected to the air valve, wherein the shell includes an upper cover that defines an opening, and the air pump includes a knob switch that extends through the opening, and wherein the air pump further comprises: a pump body; and a driving assembly located inside the pump body; wherein the knob switch extends from the pump body and is moveable in the opening along a path causing the pump body to also move along the path; and wherein the knob switch and the pump body are moveable along a transverse direction that is transverse to the path to selectively connect the air outlet to the air valve in the first position or to connect the air inlet to the air valve in the second position, depending on the positioning of the knob switch and pump body along the path, characterized in that the opening is bounded by at least a first segment and a second segment, the knob switch being movable along the path between the first segment and the second segment; wherein the shell further comprises a limit structure to retain the knob switch and pump body in the first position or the second position and prevent movement of the knob switch and the pump body along the transverse direction; wherein when the knob switch is coupled to the limit structure, the limit structure retains the knob switch and pump body in one of the first position or the second position. a pump body; and a driving assembly located inside the pump body; wherein the knob switch extends from the pump body and is moveable in the opening along a path causing the pump body to also move along the path; and wherein the knob switch and the pump body are moveable along a transverse direction that is transverse to the path to selectively connect the air outlet to the air valve in the first position or to connect the air inlet to the air valve in the second position, depending on the positioning of the knob switch and pump body along the path, characterized in that the opening is bounded by at least a first segment and a second segment, the knob switch being movable along the path between the first segment and the second segment; wherein the shell further comprises a limit structure to retain the knob switch and pump body in the first position or the second position and prevent movement of the knob switch and the pump body along the transverse direction; wherein when the knob switch is coupled to the limit structure, the limit structure retains the knob switch and pump body in one of the first position or the second position.
