In one embodiment, as shown in fig. 1, 2 and 3, an eccentric wheel 10 with lifting function comprises an eccentric wheel upper cover 100 and an eccentric wheel lower cover 200, wherein a connecting shaft 210 is convexly arranged at the middle part of the eccentric wheel lower cover 200, a connecting groove 110 is formed in the eccentric wheel upper cover, and the connecting shaft 210 is inserted into the connecting groove 110; the periphery of the eccentric wheel lower cover 200 is provided with an annular slope 220 and a blocking block 230 in a protruding manner, the height of the annular slope 220 gradually decreases from one side of the blocking block 230 to the other side of the blocking block 230, the side edge of the eccentric wheel upper cover 100 is provided with a protruding block 120 in a protruding manner, and the protruding block 120 is slidably arranged on the annular slope 220.
Specifically, the eccentric lower cover 200 is used for driving connection with a motor, and rotation of the eccentric lower cover 200 drives rotation of the eccentric upper cover 100. When the power electrode is connected to the motor, the motor may be used to drive the eccentric wheel lower cover 200 to rotate in one direction, and when the eccentric wheel lower cover 200 rotates to the point that one surface of the blocking block 230 is abutted to one surface of the protruding block 120 of the eccentric wheel upper cover 100, the eccentric wheel lower cover 200 will drive the eccentric wheel upper cover 100 to rotate. When the electrodes are reversely connected to the motor, the motor can be used to drive the eccentric wheel lower cover 200 to rotate in another direction, and when the eccentric wheel lower cover 200 rotates to the condition that the other surface of the blocking block 230 is abutted to the other surface of the protruding block 120 of the eccentric wheel upper cover 100, the eccentric wheel lower cover 200 will drive the eccentric wheel upper cover 100 to rotate. The annular slope 220 is a slope surrounding the eccentric wheel lower cover 200, that is, the heights of the annular slopes 220 at two sides of the blocking block 230 are different, and the protruding block 120 of the eccentric wheel upper cover 100 is slidably disposed on the annular slope 220, so that when the motor is connected in positive and reverse directions, the eccentric wheel lower cover 200 drives the eccentric wheel upper cover 100 to rotate, and the eccentric wheel upper cover 100 is different from the eccentric wheel lower cover 200 in height, that is, the lifting function of the eccentric wheel is realized. The eccentric wheel 10 with the lifting function can drive the bracket to eccentrically rotate, can realize the lifting function, and can further realize the function of integrally charging and discharging the air pump through the lifting function of the eccentric wheel.
In order to firmly mount the eccentric wheel 10 having the lifting function on the base in the air pump, in one embodiment, as shown in fig. 2 and 3, a mounting block 240 is protruded from a side of the eccentric wheel lower cover 200 facing away from the eccentric wheel upper cover 100. Specifically, the corresponding mounting groove is formed in the air pump base, and the mounting block 240 on the eccentric wheel lower cover 200 is correspondingly rotatably mounted in the mounting groove of the air pump base. The eccentric wheel 10 with lifting function can be stably installed on the base in the air pump through the above operation.
To facilitate the installation of the lifting eccentric 10 into the base of the air pump, in one embodiment, as shown in fig. 2 and 3, the corners of the mounting block 240 are inclined at an oblique angle. Specifically, by setting the corners of the mounting block 240 to be beveled, the mounting block 240 can be better inserted into the mounting hole of the air pump base.
In one embodiment, as shown in fig. 2 and 3, the eccentric lower cover 200 is provided with a transmission hole 250. Specifically, the driving hole 250 is formed in the mounting block 240. And the transmission hole 250 is used for being connected with a transmission shaft of a motor, so that the motor can drive the eccentric wheel lower cover 200 to rotate.
In order to facilitate the installation or the removal of the eccentric wheel 10 and the motor with the lifting function, in one embodiment, as shown in fig. 1 and 2, the transmission hole 250 penetrates through the eccentric wheel lower cover 200 and the connection shaft 210, the eccentric wheel upper cover 100 is provided with a vent hole 130, and the vent hole 130 is communicated with the connection groove 110 and the transmission hole 250. Specifically, by providing the vent hole 130, the air pressure in the connecting groove 110 and the transmission hole 250 can be kept consistent with the outside, so that the eccentric wheel 10 and the motor with lifting function can be conveniently installed or removed.
In one embodiment, as shown in fig. 1, the eccentric upper cover 100 is provided with an eccentric hole 140, the eccentric hole 140 is provided obliquely with respect to the surface of the eccentric upper cover 100, and the eccentric hole 140 is at least partially provided in the protrusion 120. Specifically, the eccentric hole 140 is used for being connected with a bracket of the leather cup. And because the bracket of the cup needs to eccentrically rotate, the eccentric hole 140 needs to be obliquely opened, and at least part of the eccentric hole 140 is opened in the protruding block 120, so that the eccentric hole 140 can be opened deeper.
In one embodiment, the annular ramp 220 is located on both sides of the stop block 230 at a height difference of at least 1 cm. Specifically, by setting the height difference between both ends of the annular slope 220 to at least 1 cm, that is, making the height difference of the lifting and lowering eccentric 10 to at least 1 cm, more functions of the lifting and lowering eccentric 10 can be achieved.
An air pump comprising an eccentric 10 with lifting function as described in any of the above embodiments. In one embodiment, the air pump is internally provided with an air vent, when the power supply is connected with the motor, the eccentric wheel 10 with the lifting function rotates clockwise at this time, the eccentric wheel upper cover 100 is lifted relative to the eccentric wheel lower cover 200, and the lifted eccentric wheel upper cover 100 drives the cup holder to block the air vent of the air pump, so that the air pump can realize the air inflation function. When the power supply is reversely connected with the motor, the eccentric wheel 10 with the lifting function rotates anticlockwise at the moment, the eccentric wheel upper cover 100 is lowered relative to the eccentric wheel lower cover 200, and the lowered eccentric wheel lower cover 200 drives the leather cup bracket to open the air discharging hole of the air pump, so that the air pump can realize the air discharging function. The air pump loading the eccentric wheel 10 having the lifting function may have an air charging and discharging integrated function.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
