Diaphragm pump with heat dissipation mechanism

A diaphragm pump with a heat dissipation mechanism comprising:

• a seat body including a rotatable drive shaft inserting therethrough and a rotating member therein connected with the drive shaft, wherein the rotating member rotates upon rotation of the drive shaft;
• a diaphragm assembly including at least one piston mechanism connected with the rotating member and moving reciprocally upon rotation of the rotating member and at least one diaphragm mechanism connected with the at least one piston mechanism and moving reciprocally upon reciprocation of the at least one piston mechanism, wherein the diaphragm assembly and the seat body are connected together and confine a first pump room in which a medium for the diaphragm assembly is received, and wherein the diaphragm assembly includes at least one medium outlet communicated with the first pump room;
• a housing with inlet and outlet channels communicated with a space in which the at least one diaphragm mechanism is disposed and including a check valve disposed therein;
• a front cover connected with the housing with inlet and outlet channels, defining a second pump room in which a fluid to be delivered is to be received, and including an inlet and an outlet communicated with the second pump room, wherein the fluid to be received is introduced in the second pump room through the inlet and forced thereout through the outlet in response to reciprocation of the at least one diaphragm mechanism;
• and
• a rotor pump assembly disposed between the rotating member and the diaphragm assembly and including a casing connected with the diaphragm assembly, wherein the casing includes a suction port communicated with the first pump room and a discharge port communicated with the at least one medium outlet, wherein the rotor pump assembly includes an outer rotor rotatably connected with the casing and an inner rotor rotatably connected with the outer rotor, wherein the inner rotor is rotatably connected with the drive shaft and rotates upon rotation of the drive shaft, wherein the outer rotor rotates upon rotation of the inner rotor, wherein the outer rotor and the inner rotor rotate at different speeds, wherein the medium is introduced in the casing upon rotations of the outer and the inner rotors and forced thereout through the discharge port, wherein the medium is reintroduced in the casing after being forced out of the at least one medium outlet and get cooled, and wherein the casing includes a casing cover connected therewith.
