Referring to fig. 1 to 7, a self-disconnection air pump with adjustable pumping pressure includes: the device comprises a pump body 1, an operating part 2, a moving part 3 and a gas-off trigger switch 4;
the movable member 3 includes a pressing block 31 communicated with the inside of the product to be inflated, and an elastic member 32 for pressing down the pressing block 31 toward the inside of the product to be inflated, in this embodiment, the elastic member 32 is a spring, and may be replaced by another elastic material capable of providing a pre-tightening force; the operating part 2 is used for changing the pretightening force of the elastic part 32; the gas-cut off trigger switch 4 is arranged on one side of the pressing block 31 far away from the interior of the inflated product; when the air pressure in the inflated product is greater than the pre-tightening force of the elastic element 32, the pressing block 31 moves towards the direction away from the inside of the inflated product to trigger the air-cut off trigger switch 4.
According to the air pump, by arranging the pressing block 31 and the elastic piece 32 and applying a pretightening force to the pressing block 31 through the elastic piece 32, the pressing block 31 can be pushed to move when the air pressure in the inflated product reaches or exceeds the pretightening force, so that the pressing block 31 is contacted with the air-off trigger switch 4 to trigger the air-off trigger switch 4, and the air pump is driven to stop inflating. Thus, the purpose of automatic gas cut-off is achieved. And the inflation target pressure in the product can be adjusted by adjusting the pretightening force of the elastic piece 32, so that the inflation pressure can be adjusted. The mode does not need to use a pressure sensor, is a scheme with a mechanical structure, and has reliable structure and lower cost.
In order to realize the above design, the present embodiment adopts the following structure:
the operating part 2 comprises a knob 21, a mandril 22 and a reversing piece 23; the reversing piece 23 is connected between the knob 21 and one end of the ejector rod 22, and the other end of the ejector rod 22 is abutted against the elastic piece 32; the reversing member 23 reverses the rotation of the knob 21 to a movement of the pressing rod along its length.
Since the knob 21 is used as the operating member 2 in this embodiment, the rotating force of the knob 21 needs to be reversed by the reversing member 23 to drive the push rod 22 to press the elastic member 32. If the toggle button is adopted, the toggle button can directly drive the ejector rod 22 to extrude the elastic element 32 without a reversing element.
Specifically, the direction-changing member 23 includes a bevel 231 disposed on the knob 21, and a pressing rod 232; the pressure lever 232 is provided with a bulge 233 which is matched and abutted with the inclined plane; the compression bar 232 is abutted against the top rod 22 along the length direction of the top rod 22; when the knob 21 rotates, the inclined edge 231 and the protrusion 233 move relatively to drive the portion of the pressing rod 232 abutting against the top rod 22 to press or lift. This achieves a reversal of the rotation of the knob 21 to the depression force of the presser bar 232 against the top bar 22.
In addition, when the user adjusts the inflation target pressure through the knob 21, it is difficult to have a clear concept, and it is not known where the adjustment is appropriate, so that the embodiment further includes a shift positioning member for positioning the knob 21 at a fixed position to set the pre-tightening force of the elastic member 32 to a preset value.
Specifically, the gear positioning member includes an elastic positioning pin 11 disposed on the pump body 1, and positioning grooves 24 disposed at intervals along the rotation direction at the bottom of the knob 21.
In order to enable a user to more clearly know the inflation hardness degree corresponding to the position of the current knob 21, the surface of the pump body 1 is provided with a mark 12 for indicating the inflation hardness degree, and the knob 21 is provided with an indicator 212; when the knob 21 is rotated to position different positioning slots 24 and the elastic positioning pin 11, the indicator 212 is aligned with different marks 12.
In order to realize the inflation and deflation functions, the pump body 1 comprises a shell 18 and an inflation and deflation assembly arranged in the shell 18; the air charging and discharging assembly comprises a rotary disc 16, a motor 13, blades 14 and a pump cavity 15;
the motor 13 is used for driving the blades 14 to rotate, and the rotary disc 16 is provided with a vent communicated with the outside atmosphere; when the operating part 2 drives the rotating disc 16 to rotate to the inflation position, the air vent is communicated with an air inlet of the pump cavity 15; when the operating member 2 drives the rotating disc 16 to rotate to the air bleeding position, the air vent is communicated with the air outlet of the pump cavity 15. The pump body 1 also has an air chamber communicating the pump chamber 15 with the product to be inflated, and a one-way valve 17 is provided at the communication between the air chamber and the product to be inflated.
When the operating member 2 rotates the turntable 16 to the inflation position, the vanes 14 rotate to draw outside air into the pump cavity 15 into the air cavity, and when the air pressure in the air cavity increases, the check valve 17 is pushed to open, so that the inflated product is inflated.
The check valve 17 also needs to be opened when the air is deflated, so the rotary disc 16 is provided with a resisting block 161; when the rotating disc 16 rotates to the air release position, the abutting block 161 abuts against the one-way valve 17 to open the one-way valve 17. The gas of the inflated product can then be drawn out by the blades 14 and vented to the atmosphere through the vent, thus effecting deflation.
The above, only be the preferred embodiment of the present invention, but the design concept of the present invention is not limited to this, and any skilled person familiar with the technical field is in the technical scope disclosed in the present invention, and it is right to utilize this concept to perform insubstantial changes to the present invention, all belong to the act of infringing the protection scope of the present invention.
