Abstract

The utility model discloses a power transformation device with simple structure, which can transfer the rotational kinetic energy into fluid kinetic energy. The device drives a crank to turn through a main driving shaft so as to drive a lever to do reciprocating motion through a connecting rod to link and drive a piston in a pump to do reciprocating movement. The whole mechanism is combined by simple mechanical components; the main driving shaft can realize the fluid-sucking purpose with a minor input torque.

Description

Power conversion apparatus

Technical field

The utility model relates to a kind of power conversion apparatus, specifically, relates to a kind of simply constructed power switching device that rotational kinetic energy is converted into fluid dynamic energy.

Background technique

In the prior art rotational kinetic energy being converted into the fairly simple mode of fluid dynamic energy is to realize by reciprocating pump, the driving device structure complexity of the reciprocating pump of prior art, the to-and-fro motion of piston normally realizes by belt gear and connecting rod, this structural requirement live axle input torque is bigger, and mechanism's volume is big.Pump at some that the traditional reciprocating pump driving structure of employing causes the too high problem of cost easily in the fluid flow smaller applications.China's description of the invention disclosed a kind of name and has been called " portable battery-operated air pump " on March 20th, 1996, notification number is " CN 1119035A ", this invention transmission is connected in an immovable point on the big angular wheel by a pair of tapered gear, connecting rod one end, the other end is fixed on the piston, the whole pump housing around the fixed pivot axi swing, has been realized the conversion of rotational kinetic energy to gas kinetic energy with connecting rod.The assembling complexity of this invention entire mechanism adopts gear transmission to increase manufacture cost, and cylinder with piston rod around the fixed pivot axi swing, cause easily to cooperate the upper deviation and wearing and tearing.

Summary of the invention

Invention order of the present utility model is at prior art piston pump driving mechanism complexity, requires the bigger problem of input torque, the new type power reforming unit of a kind of simple structure, compact structure is provided, by simple mechanical component, only need less input torque rotational kinetic energy can be converted into the kinetic energy of fluid.

For achieving the above object, power conversion apparatus of the present utility model, comprise driving shaft, crank, sleeve pipe, lever, connecting rod, the pump housing, piston, drain valve, suction valve, pump housing bottom suction valve can unidirectionally inwardly be opened, pump housing side discharge valve can unidirectionally outwards be opened, an end of crank is fixed on the driving shaft on this basis, the other end is connected in the mode of being rotationally connected with sleeve pipe, sleeve pipe links to each other with lever in the mode that is slidingly connected, the other end of lever is connected with connecting rod, and the other end of connecting rod is connected with piston.

The goal of the invention of new type power reforming unit of the present utility model is achieved in that driving shaft rotating drive crank rotates, and drives lever and does to-and-fro motion up and down, lever drives piston reciprocates by connecting rod, when piston moves upward, drain shut valve, suction valve is opened, liquid enters pump housing inside, when piston moved downward, drain valve was opened, and suction valve cuts out, pump housing internal liquid flows out through drain valve, thus the purpose that has realized pumping liquid.

The beneficial effects of the utility model are, whole driving mechanism simple structure, and part is processed easily, is assembled, and can finish the function of pumping of liquid under the less state of driving torque.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model new type power reforming unit is described in further detail and describes.

Embodiment 1, and shown in Figure 1 is a kind of embodiment of power conversion apparatus of the present utility model.Among Fig. 1, crank 2 is fixed on the driving shaft 1, is connected with sleeve pipe 3, and sleeve pipe 3 adopts the mode that is slidingly connected to be connected lever L with lever 4 _OBSegment length is greater than lever L _OASegment length, lever 4 is connected with connecting rod 5, and connecting rod 5 the other ends are connected on the piston 6, and the drain valve 9 of the pump housing 7 inside can unidirectionally outwards be opened, and suction valve 8 can unidirectionally inwardly be opened.When mechanism moves, driving shaft 1 rotates and drives lever 4 do to-and-fro motion up and down, and it is reciprocating that lever 4 drives piston 6 by connecting rod 5, when piston 6 moves upward, drain valve 9 cuts out, suction valve 8 is opened, and liquid enters the pump housing 7 inside, when piston 6 moves downward, drain valve 9 is opened, suction valve 8 cuts out, and the pump housing 7 internal liquids flow out from drain valve 9, have realized the function of pumping of liquid.

Embodiment 2, and shown in Figure 2 is a kind of portable embodiment of the present utility model, and driving shaft 1 is the rotatingshaft of motor 12 among Fig. 2, and battery 13 provides power supply for motor 12, drain valve 9 external nozzles 10, suction valve 8 external water pots 11.Described embodiment's method of operation: after opening switch 14 connection power supplys, motor 12 drives cranks 2 and rotates, and by lever 4, connecting rod 5, piston 6 is driven, and liquid is inhaled into the pump housing 7 backs from water pot 11 can obtain high-speed jet from nozzle 10 extrusion.Total is simple, and volume is less, is easy to carry, and can be used as portable medical oral cavity washing apparatus and uses.

The utility model is not limited to the scope of embodiment, and all innovation and creation that utilize the utility model design are all at the row of protection.
