Detailed description of the invention
Below by with accompanying drawing and the spirit describing the clear explanation present invention in detail, any art has usually intellectual after understanding presently preferred embodiments of the present invention, when by the technology of teachings of the present invention, can being changed and modify, it is without departing from the spirit and scope of the present invention。
Driving assembly service life for solving existing centrifugal air pump is shorter and not easily changeable problem after damaging, the present invention proposes the centrifugal air pump of a kind of improvement, it drives assembly to be positioned at the side output channel of pump, is easily changed after therefore not only can borrowing output gas flow heat radiation and damaging。
Refer to Fig. 1, it is the axonometric chart of a kind of centrifugal air pump in one embodiment of the invention。The housing 102 of centrifugal air pump 100 has and heads into QI KOU 104a and gas outlet, side 106a。When centrifugal air pump 100 works, air-flow sucks from heading into QI KOU 104a, exports through gas outlet, side 106a after the pressurizing。Housing 102 has a top cover 104, and heads into QI KOU 104a and be positioned on top cover 104。Top cover 104 is releasably coupled in the top of housing 102。Housing 102 also has lid 106 of giving vent to anger, and gas outlet, side 106a is positioned at and gives vent to anger on lid 106。In the present embodiment, housing 102 is disc, but is not limited thereto。
Refer to Fig. 2, it is the explosive view of centrifugal air pump in Fig. 1。By accompanying drawing it can be seen that electromotor 108 is fixed on the bottom in housing 102。Centrifugal air-flow assembly 109 is arranged at the top of electromotor 108 and is worked by the driving of electromotor 108。Centrifugal air-flow assembly 109 comprises pressure-applying unit 112, and this pressure-applying unit 112 is positioned between two panels rotating vane (110,114)。The rotating shaft 108a(of electromotor 108 passes through the centre bore 112e of pressure-applying unit 112) it is simultaneously connected with two panels rotating vane (110,114), and drive two panels rotating vane (110,114) to rotate with band moving air flow from heading into QI KOU 104a suction and exporting (referring to Fig. 1) through gas outlet, side 106a。
In the present embodiment, housing 102 has side output channel 103, and it has opening 103a。Assembly 120 is driven to be detachably secured in side output channel 103 (such as fixing in the way of screw locking)。The function driving assembly 120 is to change input electric energy and drive electromotor 108 to rotate。Drive assembly 120 to comprise alternating current and turn the functions such as unidirectional current, and there is some active members and passive device。After driving assembly 120 works a period of time, the operating temperature of the element on assembly can gradually rise。Drive assembly 120 to be positioned at side output channel 103 and the position close to opening 103a, accept the cooling of air-flow in side output channel 103 on the one hand, be beneficial to demolition, installation on the other hand。Additionally, drive assembly 120 can also have fin 122, so as to increasing cooling surface area, strengthen heat dissipation。In the present embodiment, side output channel 103 has flattened side walls 103b, and drives assembly 120 to be detachably secured on flattened side walls 103b (such as fixing in the way of the screw locking in scheming)。
Cover 106 to be also releasably coupled on the opening 103a of side output channel 103 additionally, give vent to anger。When lid 106 of giving vent to anger is taken apart, demolition, installation assembly 120 can be driven。In the present embodiment, lid 106 of giving vent to anger is attached on opening 103a with screw 106b。
Referring to Fig. 3 A, 3B, Fig. 3 A is the enlarged drawing of rotating vane in Fig. 2, and Fig. 3 B is the top view of rotating vane in Fig. 3 A。Each rotating vane 110(or 114) comprise plural number wind dispelling arc sheet 110b, it is held between two panels ring segment 110d。Wind dispelling arc sheet 110b forms the runner of plural number separation between two panels ring segment 110d。As rotating vane 110(or 114) rotate time, air-flow is by rotating vane 110(or 114) center air intake 110a suck, enter separate runner, and by around output (refer to the arrow in Fig. 3 A)。
Referring to Fig. 4 A, 4B, Fig. 4 A is the enlarged drawing of pressure-applying unit in Fig. 2, and Fig. 4 B is the top view of pressure-applying unit in Fig. 4 A。Pressure-applying unit 112 is disc pressure-applying unit, and it has the gas channel 112d of a plurality of radiating helical。Pressure-applying unit 112 has the base 112a of circle and the top board 112b of circle, also has a plurality of arcuate member 112c between top board 112b and base 112a, so as to forming the gas channel 112d of a plurality of radiating helical。Referring to Fig. 2, the rotating vane 114 that the air-flow of pressure-applying unit 112 comes from above, by the entrance around a plurality of gas channel 112d enter pressurized after exported (downwards) by centre bore 112e。Then, the rotating vane 110 below pressure-applying unit 112 performs spinning movement as identical in rotating vane 114 again, drives air-flow to export through side output channel 103, also can cool down driving assembly 120, thus reducing its operating temperature simultaneously。
By the invention described above embodiment it can be seen that the centrifugal air pump of the application present invention, driving assembly to be removably assembled in the output channel of side by it, making the assembly that drives during work can be subject to the cooling of output gas flow, thus reducing its operating temperature simultaneously。Additionally, the opening of side output channel has dismountable lid of giving vent to anger。When give vent to anger lid dismounting time, drive assembly can very easily by demolition, installation, without while the pump such as demolition, installation electromotor or centrifugal air-flow assembly in other structures, so as to reducing the dismounting man-hour driving assembly。
Although the present invention is with embodiment openly as above; so it is not limited to the present invention, any those of ordinary skill in the art, without departing from the spirit and scope of the present invention; when doing various variation and retouching, therefore protection scope of the present invention is when being as the criterion depending on the application as defined in claim。
