Abstract
A dual-shaft built-in pump includes a main body, provided with an air inlet and an air outlet; a motor cover, provided with an accommodating cavity having an air inflation vent and an air deflation vent; two valve bodies; a first fan blade, located between the air inflation vent and the air inlet; a second fan blade, located between the air deflation vent and the air outlet; a dual-shaft motor, configured in the accommodating cavity and having an output shaft connected with the first fan blade and the second fan blade; and a rotating member, rotatably provided on the main body and configured to drive either of the two valve bodies thereby opening the air inlet or the air outlet. The pump has simple structure, convenient fabrication and low cost.
Claims18
A dual-shaft built-in pump, comprising:
- a main body, provided with an inner cavity and an inlet communicated with the inner cavity, and the inner cavity having an air inlet and an air outlet;
- a motor cover, provided with an accommodating cavity having an air inflation vent that is communicated with the air inlet and an air deflation vent that is communicated with the air outlet;
- two valve bodies, one of the valve bodies being configured at the air inlet, and another of the valve bodies being configured at the air outlet;
- a first fan blade, located between the air inflation vent and the air inlet;
- a second fan blade, located between the air deflation vent and the air outlet;
- a dual-shaft motor, configured in the accommodating cavity and having an output shaft which has an end connected with the first fan blade and another end connected with the second fan blade;
- and
- a rotating member, rotatably provided on the main body and configured to drive either of the two valve bodies thereby opening the air inlet or the air outlet;
- wherein the rotating member is single, the rotating member is provided with a guide rail and a protruding portion protruded along the guide rail, wherein when the rotating member is rotated, the protruding portion is rotated to drive one of the valve bodies in an open state, and another of the valve bodies is in a closed state.
A dual-shaft built-in pump, comprising:
- a main body, provided with an inner cavity and an inlet communicated with the inner cavity, and the inner cavity having an air inlet and art air outlet;
- a motor cover, provided with all accommodating cavity having an air inflation vent that is communicated with the air inlet and an air deflation vent that is communicated with the air outlet;
- two valve bodies, one of the valve bodies being configured at the air inlet, and another of the valve bodes being configured at the air outlet;
- a first fan blade, located between the air inflation vent and the air inlet;
- a second fan blade, located between the air deflation vent and the air outlet;
- a dual-shaft motor, configured in the accommodating cavity and having an output shaft which has an end connected with the first fan blade and another end connected with the second fan blade;
- and
- a rotating, member rotatably provided on the main body and configured to drive either of the two valve bodies thereby opening, the air inlet or the air outlet;
- wherein the output shaft of the dual-shaft motor is perpendicular to a rotation center axis of the rotating member;
- one side of the motor cover is provided with an air inlet duct, and another side of the motor cover is provided with an air outlet duct;
- one end of the air inlet duct is communicated with the air inlet, and another end of the air inlet is communicated with the air inflation vent of the accommodating cavity;
- one end of the air outlet duct is communicated with the air inflation vent, and another end of the air outlet duct is communicated with the air deflation vent of the accommodating cavity.
