Description

A kind of water pump

Technical field

The utility model relates to fluid device more particularly to a kind of water pumps.

Background technique

In the prior art, in order to increase the oxygen content in water, it will usually be in communication with the outside in the water outlet pipe part setting of water pump Snorkel, this is applied especially to be used to be recycled or massaged the water pump of injection on the sanitary bath equipments such as bathtub, foot-washing basin.

Air is infiltrated in the water that water outlet pipe part setting snorkel can make pumping, and then improves the oxygen-containing of water body in container Amount, it is ensured that the skin of human body impregnates for a long time in water phenomena such as fatigue, asphyxia will not occurs because of anoxic, reach and thoroughly put The effect of loose body.

For the ease of manufacturing, conventional way is increased and outlet pipe vertical connection directly on outlet pipe at present Snorkel.

However, this structure makes water (flow) direction be in vertical phase with airflow direction when water flow passes through the nozzle of snorkel The state of friendship, water flow are larger to the Cutting Drag of air-flow, and the gas for seriously hindering snorkel flows into, and the air in water is caused to contain It measures less, influences the using effect of water pump.

Utility model content

The utility model aims to solve the problem that above-mentioned mentioned technical problem, provides a kind of water pump, makes to be connected to the logical of outlet pipe Tracheae can introduce more air.

The utility model is realized through the following technical scheme:

Specific embodiment

It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.

Obviously, described embodiment is a part of the embodiment of the utility model, rather than whole embodiments, is based on The embodiments of the present invention, those skilled in the art's other implementations obtained without creative efforts Example, belongs to the protection scope of the utility model.

In addition, all connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality Situation is applied, by adding or reducing connection auxiliary, to form more preferably connection structure.Each technology in the utility model is special Sign, can be with combination of interactions under the premise of not conflicting conflict.

As shown in Figure 1 and Figure 2, a kind of water pump, including pump cover 1, impeller 9 and motor, pump cover 1 are provided with the of accommodating impeller 9 One chamber 3 and the outlet pipe 2 for being connected to first chamber 3.Pump cover 1 is provided with snorkel 4, and snorkel 4 is connected to outlet pipe 2.

It is usually column due to impeller 9 and is rotated around columnar axis centre to drive water flow, first chamber 3 includes ring First bottom wall 31 of the first side wall 32 and the axis direction for being set to impeller 9 that are arranged around impeller 9, outlet pipe 2 and the first side wall 32 connections.

In order to enable the snorkel 4 for connecting outlet pipe 2 to introduce more air, as shown in figure 3, figure 4 and figure 5, snorkel 4 are set to the junction of outlet pipe 2 Yu the first side wall 32, and the first side wall 32 connects the axis of tangent line and snorkel 4 at outlet pipe 2 The angle of line is less than 90 °.

The present embodiment is by making snorkel 4 that the junction of outlet pipe 2 with the first chamber 3 for accommodating impeller 9 be arranged in, in turn It can use the interaction of fluid inertia and water (flow) direction conversion, so that the junction of 4 nozzle of snorkel and outlet pipe 2 occurs Hole position namely vacuum area, make air-flow accelerate into outlet pipe；Also, the first side wall 32 connects the tangent line at outlet pipe 2 and leads to The angle of the axis of tracheae 4 also makes the airflow direction of snorkel 4 and the water (flow) direction of outlet pipe 2 be close, gas less than 90 ° Body does not significantly alter flow direction, rapidly takes away the air of inflow convenient for water flow when flowing into, and reduces air to the maximum extent The resistance of inflow promotes the performance and usage comfort of product.

In addition, snorkel 4 is also made to keep vertical as far as possible with outlet pipe 2, facilitate the manufacturing.

As shown in figure 5, since flow velocity and pressure increase water after the driving of impeller 9, in order to suitably reduce through snorkel 4 Water velocity and pressure can be such that the first side wall 32 increases at a distance from impeller 9 along the rotation direction of impeller 9, can also make the One bottom wall 31 increases at a distance from impeller 9 along the rotation direction of impeller 9.

The first side wall 32 increase at a distance from impeller 9 along the rotation direction of impeller 9 and make the first bottom wall 31 and impeller 9 away from From the rotation direction increase along impeller 9, the drainage space for cooperatively forming first chamber 3 and impeller 9 increases, and it is appropriate to be conducive to Water velocity is reduced, shear action of the water flow to air is reduced.

The first side wall 32 increases at a distance from impeller 9 along the rotation direction of impeller 9, and outlet pipe 2 can be set into The state extended as far as possible along the tangential direction of the first side wall 32, the axis for being conducive to outlet pipe 2 is similar with water (flow) direction, is convenient for Water is discharged outside water pump.

To make water that water pump smoothly be discharged, it can make to be provided with water blocking member 7 in first chamber 3, water blocking member 7 is used for will For Waterflow-guiding to outlet pipe 2, water blocking member 7 is set to outlet pipe 2 along the side of 9 rotation direction of impeller.

Water blocking member 7 can cooperatively form the distance change relationship of first chamber 3 Yu impeller 9, and then facilitate manufacture.Water blocking Component 7 can be independent part, be also possible to that the protrusion of first chamber 3 is arranged in.

As shown in figure 3, injured to prevent finger from entering first chamber 3 through outlet pipe 2 by the rotation of impeller 9, it can be with Outlet pipe 2 is set to be provided with protective grid 5.

To be sufficiently mixed air with water, meanwhile, extend the stop of air in water to make air become minute bubbles Time, snorkel 4 can be made to be provided with the first oral area of connection outlet pipe 2, the first oral area is set to protective grid 5 close to first 3 side of chamber.

First oral area is set to protective grid 5 close to 3 side of first chamber, refers to, in the axis side perpendicular to outlet pipe 2 Upwards, the first oral area but is not limited to the first oral area entirely than protective grid 5 closer to than protective grid 5 close to first chamber 3 One chamber 3.

Air is divided after mixing with water through protective grid 5, and small bubble can be formed, and making air, the retention time is more in water Long, make water high oxygen content.

For the other details of pump cover 1, pump cover 1 is provided with water inlet pipe 6, and outlet pipe 2 is set in water inlet pipe 6, water inlet pipe 6 It is connected to first chamber 3.

Outlet pipe 2 is set in water inlet pipe 6, is allowed water pump to realize the fixation with container by water inlet pipe 6, is avoided more The fixed limitation to the accuracy of manufacture of point.

For convenience of the installation that water pump is taken over and facilitated to snorkel 4, snorkel 4 can be made to be set to the back of outlet pipe 2 To 9 side of impeller.

Snorkel 4 is set to 9 side of impeller backwards of outlet pipe 2, it may also be ensured that the axis runout impeller 9 of outlet pipe 2 Center is flowed convenient for water towards outlet pipe 2.

Above embodiments are not limited to the technical solution of the embodiment itself, can be incorporated between embodiment new Embodiment.Above embodiments are only to illustrate the technical solution of the utility model and are not intended to limit it, all without departing from this Any modification of utility model spirit and scope or equivalent replacement should all cover the range in technical solutions of the utility model It is interior.
