Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; for a better understanding of the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Fig. 1 to 4 show an embodiment of an improved air pump magnetic rod fixing structure of the present invention, which includes a pump housing 10, a motor 20, a magnetic rod 30, a guiding mechanism 40, a first cylinder assembly 50, and a second cylinder assembly 60; the motor 20 and the magnetic bar 30 are arranged in the pump shell 10, and two ends of the magnetic bar 30 are respectively connected with the first cylinder assembly 50 and the second cylinder assembly 60 which are arranged at two ends of the pump shell 10; the guide mechanism 40 is fixed in the pump housing 10 and connected with the magnetic rod 30, and the magnetic rod 30 is driven by the motor 20 to reciprocate linearly along the guide mechanism 40.

In practical use, the guide mechanism 40 serves as a limiting mechanism of the magnetic rod 30, when the motor 20 drives the magnetic rod 30 to work, the magnetic rod 30 is limited to reciprocate at a certain position, i.e., the magnetic rod 30 does not deviate from a designed swing track and suck the motor 20, so that a fixed distance is kept between the magnetic rod 30 and the motor 20, a fixed gap between the magnetic rod 30 and the motor 20 when the air pump works is ensured, the relative position deviation between the magnetic rod 30 and the motor 20 is reduced to the maximum extent, and the performance of the air pump is ensured. The utility model discloses improved generation air pump bar magnet fixed knot constructs's simple structure, install and remove conveniently.

As shown in fig. 2 to 4, the guiding mechanism 40 includes a guiding rod 41 and a fixing seat 42, and the fixing seat 42 is fixedly connected to the magnetic rod 30; the fixed seat 42 is provided with a guide hole 421, the guide rod 41 passes through the guide hole 421, two ends of the guide rod 41 are respectively fixed in the pump housing 10, and the magnetic rod 30 is driven by the motor 20 to make reciprocating linear motion along the guide rod 41. It should be noted that, in order to ensure that the magnetic rod 30 can work normally, the magnetic rod 30 reciprocates along the guide rod 41 so as not to affect the work, and the guide rod 41 should be parallel to the straight track of the magnetic rod 30 during normal work. In practical use, because the guide rod 41 is fixedly arranged in the pump housing 10 and penetrates through the fixed seat 42, and the fixed seat 42 is fixedly connected to the magnetic rod 30, when the motor 20 drives the magnetic rod 30 to reciprocate, the guide rod 41 also slides on the fixed seat 42 in a reciprocating manner, that is, the magnetic rod 30 realizes reciprocating linear motion in a state of keeping a fixed gap with the motor 20.

In order to ensure that the magnetic rod 30 is more stable when the motor 20 operates, as shown in fig. 2 and 3, the guide mechanism 40 further includes a linear bearing 43 disposed in the guide hole 421, and the guide rod 41 is engaged with the linear bearing 43, that is, the guide rod 41 is inserted into the guide hole 421 of the fixing seat 42 through the linear bearing 43, so that the friction resistance is less during the reciprocating sliding. The guide mechanism 40 ensures that the gap between the magnetic rod 30 and the motor 20 is defined, and the guide rod 41 slides more smoothly without affecting the original working trajectory of the magnetic rod 30. In addition, the fixing base 42 may be designed to be a covering structure, i.e. the lower half is a fixed base 422, and the upper half is a fixed cover 423 capable of covering, so as to facilitate the assembly of the guide rod 41 after the linear bearing 43 is disposed therethrough.

The housing 31 is a quadrilateral frame structure, and the magnetic sheet 32 is disposed in the middle of the quadrilateral frame structure, that is, the magnetic bar 30 is substantially a cuboid, and is also convenient for being fixedly connected with the fixing seat 42. In actual production, the housing 31 is generally a rectangular quadrilateral frame structure, which facilitates mass production and assembly and disassembly. In addition, since the magnetic sheet 32 generally includes two magnets of opposite polarities, there is a partition 317 in the middle within the quadrilateral frame structure.
