Abstract

The utility model relates to an automatic control type water pump held by hand. A motor and a pump body are together arranged in a housing with a handle, and a vane wheel in the pump body is connected with a rotary shaft of the motor. A sensor which is arranged in a water outlet pipeline comprises a pressure sensor, a temperature sensor and a flow velocity sensor. The surface of the housing is provided with a control panel, and the sensor and the control panel are respectively electrically connected with an input terminal of a control circuit which is arranged in the housing. An output terminal of the control circuit is electrically connected with the motor. A flow spoiling cavity is arranged between a pump cavity of the pump body and a water outlet, and a spoiler is arranged in the flow spoiling cavity. The operating state of the motor is automatically regulated, and meanwhile a setup parameter is input by the control panel by the action of the control circuit so that the aim of automatic control is reached. In addition, the turbulence of water is reduced by the flow spoiling cavity so that output water flow is stable and uniform.

Description

The portable water pump of a kind of self-controlling

Technical field

The utility model relates to water pump, particularly to the improvement of portable electric water pump.

Background technique

Present hand held, electric water pump, it is the simple combination of pump and motor, its structure comprises motor, the pump housing and the housing that has handle, the motor and the pump housing are installed in the housing jointly, impeller in the pump housing is connected with the rotating shaft of motor, the driven by motor wheel rotation is used for water lift or to water pressurization operation.Because portable water pump is usually used in some nonspecific purposes, and working environment is changeable, as water, water lift etc. in water lift, the river in water lift, the pond, lake in the flushing, well, because inhale that journey varies in size, the influence of factors such as water-outlet quantity size variation and water source changed condition, existing portable water pump does not have automatic controller, thereby cause output unstable, and need often to regulate, cause and use inconvenience.

Summary of the invention

The utility model purpose is to provide a kind of portable water pump with automatic controller, uses with convenient.

Scheme of the present utility model is: the portable water pump of a kind of self-controlling, the motor and the pump housing are installed in the housing that has handle jointly, impeller in the pump housing is connected with the rotating shaft of motor, in rising pipe, be provided with sensor, be provided with control panel at surface of shell, sensor and control panel respectively be located at housing in the control circuit input end be electrically connected, the control circuit output terminal is electrically connected with motor, sensor comprises pressure transducer, temperature transducer and flow transducer; Be provided with the flow-disturbing chamber between the pump chamber of the pump housing and water outlet, flow-disturbing is provided with spoiler in the chamber.

The utility model has the advantages that: owing to be provided with sensor in the rising pipe,, regulate the working state of motor,, reach the purpose of automatic control simultaneously by control panel input setup parameter by the effect of control circuit.In addition, the flow-disturbing chamber has reduced the eddy current of water, makes the waterflow stabilization of output, evenly, has improved using effect.

Description of drawings

The utility model is described in further detail with embodiment with reference to the accompanying drawings below.

Fig. 1 is a structure sectional view of the present utility model.

Fig. 2 is an electric theory diagram of the present utility model.

Mark among the figure: 1 housing, 2 water intakes, 3 filter screens, 4 one-way valves, 5 rising pipes, 6 sensors, 7 control circuits, 8 control panels, 9 water filling holes, 10 water outlets, 11 motors, 12 flow-disturbing chambeies, 13 impellers, 14 pump chambers, 15 pump housings, 16 suction inlets are led the way.Wherein 61 is pressure transducers, 62 temperature transducers, the 63rd, flow transducer; The 111st, machine shaft; The 121st, spoiler; The 131st, impeller shaft.

Embodiment

In conjunction with shown in Figure 1, the portable water pump of embodiment's self-controlling comprises motor 11, the pump housing 15 and the housing 1 that has handle, motor 11 is installed in the housing 1 jointly with the pump housing 15, impeller 13 is located in the pump chamber 14 of the pump housing 15, impeller shaft 131 is connected with the rotating shaft 111 of motor 11, in rising pipe 5, be provided with sensor 6, be provided with control panel 8 on housing 1 surface, sensor 6 and control panel 8 respectively be located at housing 1 in control circuit 7 input ends be electrically connected, control circuit 7 output terminals are electrically connected with motor 11.

Motor 11 impeller 13 are rotated, and water is sucked from water intake 2, and leading the way through filter screen 3, suction inlet 16 enters pump chamber 14, is entered rising pipe 5 by impeller 13 pressurization backs from flow-disturbing chamber 12 and through one-way valve 4, is discharged by water outlet 10 at last.

Control circuit 7 is according to the parameter of sensor 6 and the setting value of control panel 8 inputs, the work of control motor 11.

10 of the pump chamber 14 of the pump housing 15 and water outlets are provided with flow-disturbing chamber 12, be provided with spoiler 121 in the flow-disturbing chamber 12, spoiler 121 is along the water (flow) direction setting and the cross section of an angle is arranged with it is the tablet of helical line, current are under the leading role of spoiler 121, eddy current and wriggling have been reduced, evenly, stably from water outlet 10 output.

Referring to Fig. 2, sensor 6 comprises pressure transducer 61, temperature transducer 62 and flow transducer 63, and flow transducer 63 adopts the motor of band blade, and flow velocity is big more, and motor speed is high more, and the voltage that sends is high more, with this perception water velocity.

Each individual event sensor in the sensor 6 and control panel 8 are electrically connected with the input end of control circuit 7 respectively, control circuit 7 adopts known single chip circuit, because control circuit 7 is prior aries that common employing pressure, temperature, flow velocity signal controlled, its working principle no longer is described in detail here.

During work, when water outlet 10 is closed or stopped up, hydraulic pressure raises, and control circuit 7 automatic control motors 11 quit work; When water intake 2 lacks of water, water outlet 10 hydraulic pressure are low excessively, and control circuit 7 also automatic control motor 4 quits work; Overheated when motor 11, by temperature transducer 62 perception, control circuit 7 automatic cut-off motors 11 power supplys prevent to burn; Control circuit 7 also can be adjusted motor 11 and be operated in rational working state according to the flow velocity signal of flow transducer 63.

By control panel 8, can set various parameters, as pressure, water-outlet quantity, defence program etc., the various working staties of electric pump also show on control panel 8 simultaneously.

By single chip machine controlling circuit, water pump can be realized automatic control, has made things convenient for use.In addition, the flow-disturbing chamber has reduced the eddy current of water, makes the waterflow stabilization of output, evenly, has improved using effect.
