[0021] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific implementation manners.
[0022] For example, Figure 1 - Figure 4As shown: a kind of anti-loose type compression pump, the left side wall of piston pump 1 is provided with cover motor 2, the top of piston pump 1 is fixedly connected with fixed column 7 on the front and rear sides, the inside of two fixed columns 7 is fixedly connected with aluminum column 8, the inside of aluminum column 8 is fixedly connected with piston pump 1 on the right side wall of cover motor 2 by bolt, by increasing an aluminum column 8 in the fixed column 7 on the shell of piston pump 1, the rigidity of nylon pump body is increased, so that it is not loose by frequent change of high and low temperature, the bolt hole diameter in the inside of fixed column 7 is increased by 2.5mm, aluminum column 8 is embedded into the inside of fixed column 7 and the bolt hole of cover motor 2, then piston pump 1 and cover motor 2 are locked.
[0023] As shown in Figure 1 - Figure 3 As shown, the left and right sides of cover motor 2 are threadedly connected with support frame 3, the inside of cover motor 2 is rotatably connected with stator 4, the inside of stator 4 is fixedly connected with rotor 5, the front and rear ends of rotor 5 are rotatably connected in the inside of two support frames 3, the left and right ends of rotor 5 are supported by the support frame 3 installed on the left and right sides of cover motor 2, and when the external power supply is turned on, the current flows into the stator 4 winding assisted by the magnetically conductive silicon steel 12, and under the action of electromagnetic induction principle, the stator 4 generates alternating magnetic field to drive the rotor 5 to rotate.
[0024] As shown in Figure 1 - Figure 5 As shown, the left end outside of rotor 5 is fixedly connected with fan blade 6, the fan blade 6 on the left end of rotor 5 will rotate synchronously after being driven by rotor 5, and the air flow is pushed by fan blade 6 to cool the device cover motor 2. The right end outside of rotor 5 is fixedly connected with eccentric wheel 9, and the outside of eccentric wheel 9 is rotatably connected with piston rod 10. When the eccentric wheel 9 rotates under the driving of rotor 5, the distance between each point on the circumference of eccentric wheel 9 and the center of rotation changes constantly. The distance change makes the piston rod 10 rotatably connected with the outside of eccentric wheel 9 convert the rotary motion of eccentric wheel 9 into the linear motion of up and down reciprocation.
[0025] The bottom of piston rod 10 is arranged in the inside of piston pump 1, the left and right sides of the front side wall of piston pump 1 are both connected with two gas outlets 11, the bottom of cover motor 2 is fixedly connected with magnetically conductive silicon steel 12. With the continuous rotation of eccentric wheel 9, the piston rod 10 drives the piston to move downward, the volume of the inside cavity of piston pump 1 gradually decreases, the gas molecules are continuously squeezed in the limited cavity, the distance between molecules decreases, and the gas pressure gradually rises, entering the compression stage. When the gas pressure reaches the set opening pressure at the left and right sides of the front side wall of piston pump 1, the compressed gas overcomes the resistance of the one-way valve structure at the gas outlet 11, and is discharged from the gas outlet 11.
[0026] It needs to be explained that the utility model is a kind of anti-loose compression pump, first connect the magnetically conductive silicon steel 12 with external power supply to power supply to the device.
[0027] Anti-loose compression pump is mainly composed of two core components of piston pump 1 and shielded motor 2, piston pump 1 is located at left side, shielded motor 2 is located at its right side, wherein in the fixed column 7 of piston pump 1 top front and back two sides embed aluminum column 8, and by means of bolt passes through aluminum column 8, piston pump 1 is fastened in the right side wall of shielded motor 2.
[0028] Aluminum column 8 is embedded in the fixed column 7 of piston pump 1, and aluminum column 8 is as metal material, compared with nylon plastic, has lower thermal expansion coefficient and higher rigidity.When temperature changes, the deformation of aluminum column 8 is far less than that of nylon pump body.When the nylon pump body expands due to temperature rise or shrinks due to temperature drop, aluminum column 8 can constrain and limit the excessive deformation of the nylon pump body by virtue of its relatively stable structure, reduce the influence of deformation on the fastening force of bolt.Meanwhile, the bolt passes through aluminum column 8 to connect piston pump 1 and shielded motor 2, aluminum column 8 can disperse the shear force and tension generated by the deformation of the nylon pump body, so that the bolt always maintains a relatively stable fastening state, ensures the stable connection between piston pump 1 and shielded motor 2, maintains the normal performance and stable operation of the compression pump.
[0029] The power source of anti-loose compression pump is shielded motor 2.The key components include stator 4 and rotor 5 fixedly connected inside the stator, and magnetically conductive silicon steel 12 fixedly connected at the bottom of shielded motor 2, which can greatly enhance the efficiency of the magnetic field generated by the motor.The left and right sides of the motor are connected with support frame 3 through threads, which not only provides stable support for the motor, but also ensures that the stator 4 and rotor 5 maintain the correct relative position during operation.When the external power supply is connected, the current flows into the stator 4 winding assisted by the magnetically conductive silicon steel 12.
[0030] Under the action of electromagnetic induction principle, the stator 4 generates alternating magnetic field.Due to the unique shielded structure of the shielded motor, the alternating magnetic field will produce displacement and distortion, and then form a rotating magnetic field.Rotor 5 in the rotating magnetic field generates induced current due to electromagnetic induction, and the induced current interacts with the rotating magnetic field to generate electromagnetic force.Under the drive of electromagnetic force, rotor 5 starts to rotate at high speed around its central axis, providing initial power for the operation of the entire compression pump.
[0031] With the high-speed rotation of rotor 5, fan blades 6 fixed on the left outer side of its left end and eccentric wheel 9 fixed on the right outer side of its right end rotate synchronously.Fan blades 6 push air flow during rotation, and dissipate the heat generated by the operation of shielded motor 2, ensuring that the motor can work continuously and stably at a suitable temperature.
[0032] The eccentric wheel 9 is eccentric to its geometric center, and when rotating under the driving of the rotor 5, the distance between each point on the circumference of the eccentric wheel 9 and the rotation center changes constantly, and the distance change causes the piston rod 10 connected to the outer side of the eccentric wheel 9 to convert the rotary motion of the eccentric wheel 9 into linear reciprocating motion. The bottom of the piston rod 10 extends into the interior of the piston pump 1, thereby accurately transmitting the rotary power generated by the shield motor 2 to the piston pump 1, and providing power support for the subsequent work of the piston pump.
[0033] With the continuous rotation of the eccentric wheel 9, the piston rod 10 drives the piston to move downward, and the volume of the internal cavity of the piston pump 1 gradually decreases. In the limited cavity, gas molecules are continuously squeezed, the distance between molecules decreases, and the gas pressure gradually rises, entering the compression stage. When the gas pressure reaches the set opening pressure at the left and right sides of the front side wall of the piston pump 1, the compressed gas overcomes the resistance of the one-way valve structure at the gas outlet 11, and is discharged from the gas outlet 11, completing a complete compression cycle. This process is repeated continuously to achieve continuous gas compression output to meet the needs of different application scenarios for compressed gas.

It should be understood by those skilled in the art that the utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the utility model, and various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed.
