Chinese patent discloses a kind of water pump [Authorization Notice No. is CN204025138U], comprise the pump housing of base, band water outlet and water intake, impeller and motor, externally connected pipe is connected at water intake and water outlet, when pump working stops, the water being positioned at externally connected pipe and pump housing inner chamber can reflux, just start the air that a period of time needs to find time to be positioned at externally connected pipe and pump housing inner chamber after starting mode of pump, make idle work.Although whole water pump is placed in pump housing inner chamber when water works to be in water-filling state always, because pump motor does not arrange waterproof sealing structure, motor is easily caused to damage.Therefore, the structural design of this water pump is unreasonable, needs to carry out rational modification to it.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of self-priming water pump of reasonable in design.
The purpose of this utility model realizes by following technical proposal:
This self-priming water pump, comprise base, be located at the motor on base and the inner pump housing with pump chamber, described motor is provided with the pump shaft be arranged in pump chamber, described pump shaft is arranged with the impeller being positioned at pump chamber, the front portion of the described pump housing is provided with the water intake be communicated with pump chamber, the top of the described pump housing is provided with the water outlet be communicated with pump chamber, it is characterized in that, there is in described water outlet the annular gear edge of radially-inwardly protruding along water outlet, the inside on described annular gear edge is formed with the water channel excessively for being communicated with pump chamber and water outlet, the top on described annular gear edge is hinged with the capping that can close water channel, capping described in when motor is in running order is in open mode.
In above-mentioned self-priming water pump, described capping is in the form of annular discs, and the diameter of described capping is greater than the described diameter crossing water channel, and the madial wall of described water outlet is provided with hinged seat, and the edge of this capping is articulated with on described hinged seat.
In above-mentioned self-priming water pump, the madial wall of described water outlet is also provided with the limit structure for limiting capping pendulum angle, described limit structure comprises that be located at circular groove on water outlet madial wall and be positioned at circular groove can along the limiting stopper of this circular groove movement.
In above-mentioned self-priming water pump, described circular groove distributes along the circumference of water outlet.
When limiting stopper is the closer to the articulating point of capping and hinged seat, then the pendulum angle of capping is larger, and that is the opening angle of capping is larger, and water-outlet quantity is larger; When limiting stopper from capping and hinged seat articulating point more away from time, the opening angle of capping is less, and water-outlet quantity is less.After this limit structure is set, arbitrarily can regulate the opening angle of capping, make it meet different working environments, applied widely.
After water pump quits work, closed water channel under being sealed on the effect of self gravitation, water outlet and pump chamber are kept apart, and the water being positioned at water outlet and pump chamber can not reflux, and the next time being convenient to water pump starts, and self-priming is effective.
Compared with prior art, this self-priming water pump has the following advantages:
Its reasonable in design, by increasing closure construction, effectively can stop the water in pump chamber to reflux when water pump stops, during water pump startup next time, motor can not dally, and improves the working efficiency of water pump; The opening angle of capping can regulate as required, applied widely.

Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Self-priming water pump as shown in Figure 1, comprise base 1, be located at the motor 2 on base 1 and the inner pump housing 3 with pump chamber 30, motor 2 is provided with the pump shaft 21 be arranged in pump chamber 30, pump shaft 21 is arranged with the impeller 22 being positioned at pump chamber 30, the front portion of the pump housing 3 is provided with the water intake 31 be communicated with pump chamber 30, the top of the pump housing 3 is provided with the water outlet 32 be communicated with pump chamber 30, there is in water outlet 32 annular radially-inwardly protruded along water outlet 32 keep off along 4, the inside of annular gear along 4 is formed crosses aquaporin-4 1 for what be communicated with pump chamber 30 and water outlet 32, annular gear is hinged with the capping 5 that can close aquaporin-4 1 along the top of 4, when motor 2 is in running order, capping 5 is in open mode.
In the present embodiment, capping 5 is in the form of annular discs, and the diameter of capping 5 was greater than the diameter of aquaporin-4 1, and as depicted in figs. 1 and 2, the madial wall of water outlet 32 is provided with hinged seat 6, and the edge of this capping 5 is articulated with on hinged seat 6.
As depicted in figs. 1 and 2, the madial wall of water outlet 32 is also provided with the limit structure for limiting capping 5 pendulum angle, limit structure comprises that be located at circular groove on water outlet 32 madial wall 71 and be positioned at circular groove 71 can along the limiting stopper 72 of this circular groove 71 movement, and circular groove 71 distributes along the circumference of water outlet 32.
Fig. 2 is the structural representation of capping 5 when being in opening state, and when limiting stopper 72 is the closer to the articulating point of capping 5 with hinged seat 6, then the pendulum angle of capping 5 is larger, and that is the opening angle of capping 5 is larger; When limiting stopper 72 from capping 5 and hinged seat 6 articulating point more away from time, the opening angle of capping 5 is less.After this limit structure is set, arbitrarily can regulate the opening angle of capping 5, make it meet different working environments, applied widely.
