Label declaration
1: portable vacuum pump apparatus; 2: apparatus main body; 4: the air inlet oral area; 5: the exhaust oral area; 20: motor driver; 21: solid of rotation; 23: as the rotor shaft of running shaft; 24: motor driver inserts oral area.
Embodiment
Below, describe with reference to the portable vacuum pump apparatus of accompanying drawing an embodiment of the invention.
In Fig. 1 to Fig. 3,1 is portable vacuum pump apparatus, this portable vacuum pump apparatus 1 is the portable small-sized vane pump unit that uses when for example air conditioner piping supplier carries out the vacuum draw operation, and described vacuum draw operation is the operation that deflates in the freon gas body and function pipe arrangement of family expenses or business air conditioner (air bells conditioner).
Portable vacuum pump apparatus 1 has profile and constitutes roughly rectangular-shaped apparatus main body 2.Be formed with rotor chamber 3 cylindraceous in the apparatus main body 2, on apparatus main body 2, also be formed with air inlet oral area 4 and exhaust oral area 5 communicatively with rotor chamber 3 respectively.In air inlet oral area 4, be equipped with: suction valve 6; Support this suction valve 6 and make its valve seat that stops 7; To the spring 8 of suction valve 6 towards the valve seat 7 side application of forces; And filter 9.In addition, apparatus main body 2 comprises: housing body 11; Utilize fixed block etc. to be fixed on two housing lids 13 on this housing body 11 etc. by O RunddichtringO 12 with being airtight shape.
In addition, rotatably be provided with solid of rotation 21 on apparatus main body 2, this solid of rotation 21 is by from the rotating force of motor driver 20 and to the predetermined direction rotation, and the pump unit that the air from air inlet oral area 4 is compressed.
Solid of rotation 21 has rotor shaft 23, and this rotor shaft 23 is rotatably supported in apparatus main body 2, and is positioned at the running shaft of rotor chamber 3 with the state that runs through rotor chamber 3.The axial end portion outside the apparatus main body 2 of being positioned at running shaft 23, promptly, for example the axial end portion of giving prominence in the front from apparatus main body 2 of rotor shaft 23 is formed with motor driver insertion oral area 24, this motor driver insert oral area 24 be used to insert can be portable small-sized electric driver 20, and this motor driver inserts oral area 24 and forms concavity at the end face of this rotor shaft 23.Motor driver inserts oral area 24 and has the shape chimeric with the drive portion 20a of motor driver 20, for example, forms the axially extended hexagonal configuration along rotor shaft 23.
Outer circumferential side in the part that is positioned at rotor chamber 3 of rotor shaft 23 is provided with integratedly and carries out eccentric rotor rotated 25 in rotor chamber 3.Be formed with manyly on the rotor 25, in each slip slot part 26, be mounted slidably the blade 27 of rectangular plate shape two slip slot parts 26 that radially extend along rotor 25.Dispose spring 28 between described two blades 27 as application of force unit, by the active force of this spring 28, the exterior edge face of each blade 27 be pressed against all the time in the apparatus main body 2 on the internal surface of rotor chamber 3.In addition, solid of rotation 21 has: rotor shaft 23, rotor 25, blade 27 and spring 28 etc.
Below, action of above-mentioned portable vacuum pump apparatus 1 etc. is described.
When family expenses or commercial air-conditioning are set, in Freon gas being filled into the freon gas body and function pipe arrangement that connects indoor set and outdoor unit before, must carry out the vacuum draw operation that in this freon gas body and function pipe arrangement, deflates.
Using the portable vacuum pump apparatus 1 that does not have driving source to carry out under the situation of vacuum draw operation, after the air inlet oral area 4 that connects freon gas body and function pipe arrangement and apparatus main body 2, the motor driver that the drive portion 20a of motor driver 20 is inserted into the rotor shaft 23 of solid of rotation 21 inserts in the oral area 24, makes drive portion 20a and motor driver insertion oral area 24 chimeric each other.
Then, when the operation unit 20b to motor driver 20 carries out opening operation when making motor driver 20 work, the drive portion 20a rotation of motor driver 20, rotating force passes to rotor shaft 23 from this drive portion 20a, thereby rotor 25 rotates in rotor chamber 3 with blade 27.
When rotor 25 rotates in rotor chamber 3 with blade 27, enter air in the rotor chamber 3 after being compressed to desirable pressure from air inlet oral area 4, discharge from exhaust oral area 5.
According to this portable vacuum pump apparatus 1, because the motor driver of rotor shaft 23 that can be by motor driver 20 being inserted into solid of rotation 21 inserts in the oral area 24 and makes this motor driver 20 work, the rotor 25 of solid of rotation 21 is rotated in rotor chamber 3, therefore, air conditioner piping supplier can carry out the vacuum draw operation that deflates easily and efficiently by using the motor driver of carrying usually 20 in the freon gas body and function pipe arrangement of air-conditioning.
In addition, be not only motor driver 20, portable vacuum pump apparatus 1 itself also is portable, and, owing to compare more small-sized (for example for existing product 1/10) with existing product, therefore, can extremely easily carry.
In addition, in the above-described embodiment, the structure with suction valve 6 is illustrated, though not shown, also can be structure with suction valve 6.
In addition, be not limited to have the vane pump of tabular blade 27, also can be applied to the pump of other kinds such as gear pump.
