Technical field

The utility model system belongs to a kind of pump, refers to a kind of electric pump especially, and it can have the firm fastener that is pivoted structure and can fastens fast.

Background technique

Electric pump is common device, is used for that air mattress, Inflation water pond etc. is blown body and inflates and exit.

Traditional wherein a kind of electric pump system can drive motor in the electric pump by dryelement cell is installed, this electric pump mainly ties up to and is formed with a battery chamber that can hold a plurality of dryelement cell in the shell, and shell aperture is provided with a cap that can cover opening, this cap one end is connected to one section on shell by the elastic element of a rubber system, after being opened, cap still can connect shell, avoid cap to lose, in addition, cap and shell are provided with a fastener so that can fasten shell and cap.

Yet, elastic element is not firm, cap still can make elastic element come off when suffering big slightly pulling force or rupture, and causes cap to separate with shell, in addition, fastener system comprises a pin thread, a box and a c-shaped metal tommy bar and forms, after treating that pin thread and box fasten, need pull this tommy bar that is arranged on the pin thread could tightly be stuck in pin thread on the box, Gu the structure of fastener is very complicated, increase built-up time, cause the electric pump cost to increase.

Summary of the invention

The utility model people according to connecting rod between existing electric pump electricity cap and the shell not firm and buckle structure cross to the complicated shortcoming such as built-up time that expends, improve its deficiency and defective, and then create a kind of electric pump.

The utility model main purpose system provides a kind of electric pump, being connected firmly between its shell and the cap, and buckle structure simply need not be assembled.

For reaching above-mentioned technological means, be to make this electric pump include:

One shell is formed with a battery chamber at least one battery is installed in it, be formed with an opening that is connected with the battery chamber at outer casing bottom;

One cap is to be hubbed on shell one end and can to cover shell aperture;

One connection part, system is arranged between shell and the cap, make cap on shell, pivot, this connection part includes one first pivot joint block, one second pivot joint block and a connecting rod, this first and second pivot joint block is a hard material, and be respectively formed on the side of shell and cap, this connecting rod is a hard material, and is hubbed on respectively on first and second pivot joint block with two ends;

One fastener, system is fixed on the shell in the time of can making cap cover shell aperture, and include a clipping block and a button hook, this clipping block is integrally formed on cap, this button hook system is slightly c-shaped, has elasticity, and is integrally formed on shell, and can be when cap covers shell aperture, fasten clipping block and cap is fixed on the shell;

One motor is the top that is arranged on shell, and motor is provided with a rotating shaft that passes cover top portion;

One fan is to be arranged in the rotating shaft to be positioned at outside the cover top portion; And

One fan cover cap is to be installed in cover top portion and to cover fan, is formed with an air chamber in the fan cover cap, covers to run through at fan guard to be formed with a suction port that is communicated with air chamber and an air outlet that is communicated with air chamber.

By above-mentioned technological means, connection part system is formed with first, second pivot joint block and three rigid element of connecting rod, therefore firm in structure, what the elastic element of conduct connection usefulness came on more traditional electric pump is reliable, can effectively avoid cap on shell, to come off, in addition, the clipping block of fastener and button hook all are integrally formed on cap and the shell, so can on manufacturing shell and cap, form clipping block and button hook in the lump, therefore the built-up time of avoiding other assembling fastener to spend can effectively reduce the manufacture cost of electric pump.

Be installed with at least one battery terminal set in the battery compartment.

Aforementioned cover top portion runs through and is formed with a mounting hole and passes outside the shell for motor shaft.

Aforementioned fan is an impeller.

Aforementioned connecting rod is that H shape has two lateral plates, and the two ends of each lateral plate are hubbed on respectively on first and second pivot joint block.
