Embodiment
Below will clearly demonstrate spirit of the present invention with accompanying drawing and detailed description, under any, in technical field, have and conventionally know that the knowledgeable is after understanding preferred embodiment of the present invention, when can be by the technology of teachings of the present invention, change and modification, it does not depart from spirit of the present invention and scope.
For solve driven unit working life of existing centrifugal air pump shorter and damage after not easily changeable problem, the present invention proposes a kind of centrifugal air pump of improvement, its driven unit is positioned at the side output channel of pump, after therefore not only can and damaging by means of output gas flow heat radiation, is easy to change.
Please refer to Fig. 1, it is the stereogram of a kind of centrifugal air pump in one embodiment of the invention.The housing 102 of centrifugal air pump 100 has the gas port of heading into 104a and side air outlet 106a.During centrifugal air pump 100 work, air-flow sucks from heading into gas port 104a, in pressurization, by side air outlet 106a, exports.Housing 102 has top cover 104, and heads into gas port 104a and be positioned on top cover 104.Top cover 104 is removably engaged in the top of housing 102.Housing 102 also has to give vent to anger and covers 106, and side air outlet 106a is positioned to give vent to anger and covers on 106.In the present embodiment, housing 102 is discs, but not as limit.
Please refer to Fig. 2, it is the explosive view of centrifugal air pump in Fig. 1.From accompanying drawing, motor 108 is fixed on the bottom in housing 102.Centrifugal air-flow assembly 109 is arranged at the top of motor 108 and is subject to the driving of motor 108 and works.Centrifugal air-flow assembly 109 comprises pressure-applying unit 112, and this pressure-applying unit 112 is positioned between two rotation blades (110,114).The rotating shaft 108a(of motor 108 passes through the center hole 112e of pressure-applying unit 112) connect two rotation blades (110,114) simultaneously, and drive two rotation blades (110,114) rotation suck and export (referring to Fig. 1) through side air outlet 106a from heading into gas port 104a with band moving air flow.
In the present embodiment, housing 102 has side output channel 103, and it has opening 103a.Driven unit 120 is for example removably fixed on, in side output channel 103 (fixing in the mode of screw locking).The function of driven unit 120 is to drive motor 108 rotations in order to conversion input electric energy.Driven unit 120 comprises Ac and turns the functions such as direct current, and has some active members and passive device.When driven unit is after 120 work a period of times, the operating temperature of the element on assembly can raise gradually.Driven unit 120 is positioned at side output channel 103 and approaches the position of opening 103a, accepts the cooling of side output channel 103 interior air-flows on the one hand, is beneficial on the other hand disassemble or assemble.In addition, driven unit 120 can also have radiating fin 122, so as to increasing cooling surface area, strengthens heat dissipation.In the present embodiment, side output channel 103 has flattened side walls 103b, and driven unit 120 is removably fixed on flattened side walls 103b upper (for example fixing in the mode of the screw locking in scheming).
In addition, give vent to anger and cover 106 and be also removably engaged on the opening 103a of side output channel 103.When giving vent to anger, cover 106 while taking apart, can disassemble or assemble driven unit 120.In the present embodiment, give vent to anger and cover 106 and be attached on opening 103a with screw 106b.
Referring to Fig. 3 A, 3B, Fig. 3 A is the enlarged view of rotation blade in Fig. 2, and Fig. 3 B is the plan view of rotation blade in Fig. 3 A.Each rotation blade 110(or 114) comprise plural wind dispelling arc sheet 110b, it is held between two rings shape sheet 110d.Wind dispelling arc sheet 110b forms the runner that plural number is separated between two rings shape sheet 110d.As rotation blade 110(or 114) while rotating, air-flow is by rotation blade 110(or 114) center air intake 110a suck, enter the runner of separation, and by output (please refer to the arrow in Fig. 3 A) around.
Referring to Fig. 4 A, 4B, Fig. 4 A is the enlarged view of pressure-applying unit in Fig. 2, and Fig. 4 B is the plan view of pressure-applying unit in Fig. 4 A.Pressure-applying unit 112 is disc pressure-applying unit, and it has the air-flow path 112d of a plurality of radiation spirals.Pressure-applying unit 112 has circular base 112a and circular top board 112b, also has a plurality of arcuate member 112c between top board 112b and base 112a, so as to forming the air-flow path 112d of a plurality of radiation spirals.Referring to Fig. 2, the air-flow of pressure-applying unit 112, from the rotation blade 114 of top, is entered after pressurization by center hole 112e output (downwards) by a plurality of air-flow path 112d entrance around.Then, the rotation blade 110 of pressure-applying unit 112 belows is carried out spinning movement as identical in rotation blade 114 again, drives air-flow through 103 outputs of side output channel, also cooling driven unit 120 simultaneously, thus reduce its operating temperature.
From the invention described above mode of execution, apply centrifugal air pump of the present invention, by its driven unit, be removably assembled in side output channel, the driven unit while making work can be subject to the cooling of output gas flow simultaneously, thereby reduces its operating temperature.In addition, the opening of side output channel has dismountable lid of giving vent to anger.When giving vent to anger when dismounting lid, driven unit can be very easily by disassemble or assemble, and without other structures in the pumps such as while disassemble or assemble motor or centrifugal air-flow assembly, so as to reducing the dismounting man-hour of driven unit.
Although the present invention with mode of execution openly as above; so it is not in order to limit the present invention; any those of ordinary skills; without departing from the spirit and scope of the present invention; when doing various changes and retouching, so protection scope of the present invention is when being as the criterion depending on the application's claim person of defining.
