Description
Technical field
The present invention relates to a kind of pump, more particularly to one kind improvement water dispenser body water storage and return-flow structure, to shorten
Assemble the suction pump of machining period.
Background technology
Pump is the device that transportation work fluid is commonly used in a kind of daily life, working fluid, such as：Water,
Into after the water dispenser body of pump, working fluid is pressurizeed by the operating of water dispenser body internal impeller, then will
Working fluid sends out water dispenser body to reach the purpose of working fluid conveying.
The pump of prior art, it refer to shown in Fig. 4 and Fig. 5, motor 60 is installed on the side of water dispenser body 70
Face, the interval of water dispenser body 70 are formed there through an inlet portion 701 and an export department 702, and assembling seat 71 is located at water
The another side of fuselage 70, the concave shape of assembling seat 71 are formed there through into assembly chamber 710 and in assembly chamber 710
Opening 711, opening 711 are communicated in export department 702, and connecting support 72 is located at the centre of assembly chamber 710 and entered
One step is recessed to form water-supplying chamber 720, and water-supplying chamber 720 is communicated in inlet portion 701 and export department 702, motor
60 power transmission shaft 61 is worn in water-supplying chamber 720, and impeller 91 is located in water-supplying chamber 720 and is installed on biography
On moving axis 61, water dispenser lid 80 is installed on connecting support 72, and the return port 82 of the centre of water dispenser lid 80 connects
In water-supplying chamber 720, also, the baffle portion 81 at the lateral margin of water dispenser lid 80 corresponds to opening 711 in position
And the assembling seat 710 of water dispenser body 70 is installed on inner edge one gap of wall formation of assembly chamber 710, end cap 92,
The inner edge wall of end cap 92 forms storage chamber 920 with assembly chamber 710, and storage chamber 920 is connected by return port 82
Pass-out hydroecium 720, and by baffle portion 81 and the gap area export department of the inner edge wall of assembly chamber 710
702。
When working fluid enters water-supplying chamber 720 by the inlet portion 701 of water dispenser body 70, pressurizeed by impeller 91
Left by export department 702, and during working fluid pumps, the working fluid of part passes through baffle plate
The gap of portion 81 and the inner edge wall of assembly chamber 710 and flow into storage chamber 920, baffle portion 81 and assembly chamber
710 gap at opening 711, the amount of storage chamber 920 is entered for adjustment work fluid, to keep big
Partial working fluid is discharged by export department 702.
When the inflow that working fluid enters water dispenser body 70 is reduced or stopped, the water storage in storage chamber 920
Water-supplying chamber 720 is entered by the return port 82 of water dispenser lid 80, gone out with filling up during working fluid supply cutout
The volume vacancy of fluid in hydroecium 720, it is ensured that keep the state overflowed in water-supplying chamber 720 at any time, work as work
When fluid is supplied and makes air with entering in water-supplying chamber 720 again, the inner air of water dispenser body 70 can be accelerated
Discharge, make pump can quickly by air discharge and be operated with high efficiency mode.
Prior art pump is the purpose for reaching water storage, and forms the structure of opening 711 in water dispenser body 70, together
When hydrous water cover 80 baffle portion 81 setting so that the work of water dispenser body 70 is left by export department 702
Make fluid to be capable of in the entrance storage chamber 920 of part, however, this technological means, but causes pump manufacturer
The bought finished product of water dispenser lid 80 must be directed to, and row processing is to form baffle portion 81 again, simultaneously, it is necessary to Yu Shui
The drilling of cover 80 forms return port 82, thereby results in the overall processing of pump, assembling man-hour increase, makes pump
Production efficiency reduces.

The pressure cover 53 is against the valve 52 and is fixed in the interval lid 51 and the assembling seat 11, by this
Specific embodiment disclosed in invention schema is understood, is worn the pressure cover 53 by multiple bolts 500 and is somebody's turn to do
Lid 51 is spaced to be fixed on the assembling seat 11；A pressure chamber is formed between the pressure cover 53 and the valve 52
530, the pressure chamber 530 is filled with pressure fluid, and the pressure fluid can be compressed air.
In the present invention water pump structure operation, when working fluid be capable of regular supply by the entrance
When portion 101 enters the water-supplying chamber 120, the working fluid to be pressurizeed by impeller 40 is i.e. by the export department 102
Leave, while partial pressurized working fluid is flowed into the water storage cavity 510 by the water storage hole 13, should
Working fluid in water storage cavity 510 then enters the start chamber 520 via the through hole 511 of the interval lid 51
Inside, then the internal process fluid of start chamber 520 is for the valve 52 one pressure of formation so that the valve
Pressure between the start chamber 520 and the pressure chamber 530 of 52 both sides is balanced.
Opposite, when working fluid short supply, into the amount of working fluid in the water-supplying chamber 120 at once
Reduce, because the amount of working fluid of the water storage hole 13 and the water storage cavity 510 inflow start chamber 520 is gradual
Tail off so that the pressure in the start chamber 520 forces the valve less than the pressure in the pressure chamber 530
Film 52 deforms start to produce a pushing effect, makes the water storage of the water storage cavity 510 pass through the fuselage return port
14 enter in the inlet through hole 121 subsequently into the water-supplying chamber 120, the work inserted in the water-supplying chamber 120
Making fluid can make the air in the water-supplying chamber 120 quickly discharge, to maintain the suction pump of the present invention with high efficiency
Running；Certainly, in pump manufacturer on the premise of the water dispenser lid 20 forms the cover return port 21, the storage
The water storage of water cavity 510 can also be entered in the water-supplying chamber 120 by the cover return port 21.
The water pump structure of the present invention, it is not excluded that in formation fuselage return port 14 in the assembly chamber 110
Outside, the technical characteristic of the cover return port 21 still is formed in the water dispenser lid 20 simultaneously, this means, pump manufactures
Business can determine according to demand, after the water dispenser body 10 forms the fuselage return port 14, while coordinate and be somebody's turn to do
Water dispenser lid 20 forms the cover return port 21, or, fuselage return port 14 and the water of the water dispenser body 10
The cover return port 21 of cover 20 selects a shaping.
In the present invention, by directly forming the water storage hole 13 in the assembly chamber 110 of the water dispenser body 10
With the fuselage return port 14 so that during the operating fluid crosses water outlet through hole 122, partial working stream energy
It is enough entered by the water storage hole 13 in the water storage cavity 510 save the purpose of working fluid to reach, also, should
Working fluid in water storage cavity 510 can also return to the inlet through hole 121 by the fuselage return port 14, from
And meet to fill up demand during working fluid cutout, therefore, the present invention can save in the past another for water dispenser lid
Row is processed and forms the demand of baffle portion, and thus shortens pump overall processing, the man-hour of assembling, is lifted simultaneously
The operating efficiency of pump production, in addition, the present invention also can be according to demand, and determines the machine of the water dispenser body 10
The formation of the cover return port 21 of body return port 14 and/or the water dispenser lid 20, thus Ling Beng manufacturers can
The selection of elasticity is used.
Certainly, the present invention can also have other various embodiments, in the feelings without departing substantially from spirit of the invention and its essence
Under condition, those skilled in the art work as can make various corresponding changes and deformation according to the present invention, but
These corresponding changes and deformation should all belong to the protection domain of appended claims of the invention.
