Description
Technical field
This utility model is related to domestic electric appliance technical field, specially a kind of pressure release water pump.
Background technology
Water-aspirator pressure in the market can reach 300KPa (0.3BAR) left and right, if using on domestic small household appliances
When, have a potential safety hazard, such as coffee machine, when being blocked by coffee powder if there is outlet, water pump in normal work, hydraulic pressure
More than 300KPa can be rapidly reached, when now water-filled pipe is by incessantly so big pressure, the situation for having explosion occurs, then
Will intake in coffee machine, short-circuit conditions easily occurs in internal circuit, pole user life security of endangering, while the outlet of the pump housing
Pressure is larger, it is easy to water outlet, affects to use.
To solve the above problems, therefore, it is proposed that a kind of pressure release water pump.
Utility model content
The purpose of this utility model is to provide a kind of pressure release water pump, possesses the hydraulic pressure to pump housing outlet and reaches pressure release mesh
Advantage, solving the hydraulic pressure of the outlet of the pump housing used in existing small household appliances can not access preferably control
Cause the situation for having explosion to occur and short-circuit conditions easily occurs in internal circuit, the problem of pole user life security of endangering.
For achieving the above object, this utility model provides following technical scheme：A kind of pressure release water pump, including the pump housing, non-return
Valve block and pressure relief device, the crown center of the pump housing is provided with top cover, and the upper surface of top cover is provided with three groups of screws near edge, and screw is in
Annular spread, non-return valve block is installed inside the outlet of the pump housing in beveled structure, and the outward flange of non-return valve block is provided with ring
The opening of shape distribution, the pump housing is respectively provided on two sides with water inlet and outlet, and water inlet is corresponding with outlet, and in outlet
Portion installs and is provided with pressure relief device, and pressure relief device includes rubber plug, spring and O-ring seal.
Preferably, sheathed spring on the rubber plug, O-ring seal is located at rubber plug and the junction of outlet.
Preferably, 3 screws being matched therewith are loaded in the screw that the top cover upper surface is provided with.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, this utility model increases pressure relief device when outlet is blocked by the outlet in the pump housing, and pressure can be arranged automatically
Let out, maximum pressure can be stablized in 50~80KPa all the time, do not result in the generation of pipelines from bursting situation, thoroughly lift little peace electricity and produce
Product quality.
2nd, this utility model is improved to as three-chip type, reduction outlet pressure by outlet non-return valve structure, it is easy to
Water outlet, reduces load.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Fig. 1-6 are referred to, this utility model provides a kind of technical scheme：A kind of pressure release water pump, including the pump housing 1, check-valves
Piece 8 and pressure relief device, the crown center of the pump housing 1 is provided with top cover 4, and the upper surface of top cover 4 is provided with three groups of screws 41, spiral shell near edge
Hole 41 is distributed in a ring, and non-return valve block 8 is installed inside the outlet 3 of the pump housing 1 in beveled structure, and non-return valve block 8 is outer
Edge is provided with the opening of annular spread, and the pump housing 1 is respectively provided on two sides with water inlet 2 and outlet 3, water inlet 2 and the phase of outlet 3
Correspondence, and the installation of the inside of outlet 3 is provided with pressure relief device, pressure relief device includes rubber plug 5, spring 6 and O-ring seal 7.
Operation principle of the present utility model and it is improved by：By sheathed spring 6 on rubber plug 5, O-ring seal 7 sets
In rubber plug 5 and the junction of outlet 3, when outlet 3 is plugged, when pressure increases, rubber plug 5 can be open, water
Water inlet 2 can be flowed back to, so as to reach the purpose of pressure release, it is ensured that water-aspirator pressure can be adjusted arbitrarily in 50~80KPa
The pressure of spring 6 is such as increased or decreased controlling water-aspirator pressure.In addition, in the case that outlet 3 is not blocked, due to water outlet
End pressure is placed on 0KPa, and less than the pressure of spring 6, rubber plug 5 will not be opened, and water side water will not blow back into water inlet end,
So as to not interfere with pump capacity size when ensureing to use.
By loading 3 screws being matched therewith in the screw 41 that the upper surface of the top cover 4 is provided with, you can ensure sealing
Property, uniform force also can reduces cost.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
