FIELD OF THE INVENTION [0001] The present invention relates to a pump; more particularly, relates to driving a piston having a magnetic element and a hollow flow path to reciprocate for pumping a fluid by using an electromagnetic element on a shell. DESCRIPTION OF THE RELATED ARTS [0002] General pumps include rotating pumps and reciprocating pumps, which are driven by motors to move blades or pistons to pump fluids. The fluids of the pumps may leak owing to defects or abrasions of the pumps; or, the pumps may even further fail in obtaining required fluid pressures. [0003] A prior art, "a liquid-cooling heat sink pump", is proclaimed in Taiwan, as shown in FIG. 6, comprising a pump shell 3 with a cooling liquid entrance 31 and a cooling liquid exit 32; a partition 4; an assembly of a rotor and blades 5; and a stator 6. Therein, the partition 4 divides the pump shell 3 into two isolated spaces, where one is a space containing the cooling liquid entrance 31 and the cooling liquid exit 32, and the other is a space having no entrance or exit for the cooling liquid. The assembly of the rotor and blades 5 is deposed in the space containing the cooling liquid entrance 31 and the cooling liquid exit 32. The stator 6 is deposed in the space having no entrance or exit for the cooling liquid; and is connected with a power supplier through a wire, which is totally isolated from the tube system of the prior art. The stator 6 drives the rotor and blades 5 at the outside of the tube system; and the blades 5 drives the cooling liquid flowing in the tube system. [0004] Another prior art, "Pumping assembly using treadle", is proclaimed in Taiwan as shown in FIG. 7, where a pump is deposed at bottom of a treadle (not shown in the figure). Therein, the main body 71 of the pump 7 is fixed with a cover 8 to form an inner room; a spring 91, a plate 92 and a button 93 are sequentially deposed in the inner room; the button 93 is penetrates out a top ceiling of the cover 8 corresponding to a hole on the treadle with the top surfaces of the button 93 and the treadle at almost the same height; and, inlet/outlet tubes 73 and their check valves 74 are deposed at two side ends of the main body of the pump 7. [0005] Although the above prior arts pump fluids, their efficiencies may not remain the same after a period of use resulting in damage or aging. Or, the lockings of the parts may be loosened resulting in leaking the fluid. Hence, the prior arts do not fulfill users' requests on actual use. SUMMARY OF THE INVENTION [0006] The main purpose of the present invention is to pump fluid with an improved leakage prevention. [0007] To achieve the above purpose, the present invention is an electromagnetic reciprocating pump, comprising a shell having a fluid entrance and a fluid exit; a piston deposed in the shell; and an electromagnetic element at the outside, where an entrance check valve is deposed at the fluid entrance; an exit check valve is deposed at the fluid exit; the piston divides the shell into a first room and a second room; the piston has a hollow flow path along an axis of the piston, and a piston check valve at an end of the flow path; magnetic elements are deposed at two ends of the piston; the shell has electromagnetic elements deposed at two ends, or has an electromagnetic element covered on the side surface; the electromagnetic element is connected with an electric power supplier to obtain pole of the electromagnetic element to produce forces of attraction and repulsion toward the magnetic element of the piston for the piston to reciprocate; fluid is controlled by the entrance check valve, the exit check valve and the piston check valve to flow in one-way direction. Accordingly, a novel electromagnetic reciprocating pump is obtained. BRIEF DESCRIPTION OF THE DRAWINGS [0008] The present invention will be better understood from the following detailed descriptions of the preferred embodiments according to the present invention, taken in conjunction with the accompanying drawings, in which [0009] FIG. 1 is a perspective view showing a first preferred embodiment according to the present invention; [0010] FIG. 2 is a cross-sectional view of the pump; [0011] FIG. 3A is a cross-sectional view showing the movement of the piston toward the fluid entrance; [0012] FIG. 3B is a cross-sectional view showing the movement of the piston toward the fluid exit; [0013] FIG. 4 is a perspective view showing a second preferred embodiment; [0014] FIG. 5 is a cross-sectional view of the pump; and [0015] FIG. 6 is a cross-sectional view of a prior art. [0016] FIG. 7 is a cross-sectional view of another prior art. DESCRIPTION OF THE PREFERRED EMBODIMENT [0017] The following descriptions of the preferred embodiments are provided to understand the features and the structures of the present invention. [0018] Please refer to FIG. 1 and FIG. 2, which are a perspective view and a cross-sectional view showing a first preferred embodiment according to the present invention. As shown in the figures, the present invention is an electromagnetic reciprocating pump 1, comprising a shell 11 having a fluid entrance 111 and a fluid exit 112; a piston 12 having a hollow flow path 121; and a pair of electromagnetic elements 13. [0019] The shell 11 has the fluid entrance 111 and the fluid exit 112 at two ends; the fluid entrance 111 and the fluid exit 112 are connected with tubes 2 respectively; an entrance check valve 1111 and an exit check valve 1121 are respectively deposed at places where the tubes 2 are connected with the fluid entrance 111 and the fluid exit 112; the entrance check valve 1111 controls an entrance of fluid into the pump 1; and, the exit check valve 1111 controls an exit of the fluid from the pump 1.
