The housings 30 may further be solidly coupled and secured to the base member 11 with such as adhesive materials, welding processes, latches or fasteners (not shown), or the like.
  • As also shown in FIGS. 3-7, the housing 30 further includes a peripheral wall or casing 40 protruded or extended from the housing member 32 and having a space 41 formed in the casing 40, and further includes one or more orifices 42 formed therein and communicating with the upper chamber 35 of the housing 30 and the space 41 of the casing 40 (FIGS. 4, 6-7), and further includes one or more apertures 43 formed therein and communicating with the lower chamber 36 of the housing 30 and the space 41 of the casing 40 (FIGS. 5-7), A bladder 50 is attached or secured onto the casing 40 of each of the housings 30 and includes a compartment 51 formed therein (FIGS. 3-7) and communicating with the space 41 of the casing 40.
  • The bladders 50 are deformable or compressible and expandable to pump or force the air or water or fluid or liquid to flow through the orifices 42 or the apertures 43 of the housing 30, which will be discussed hereinafter. The housing 30 further includes a hook or retainer 44 provided thereon, such as formed integral with or extended from the housing member 32, or the retainer 44 includes a dovetail member 45 slidably engaged in a dovetail slot 46 of the housing member 32 or of the housing 30, and a latch or stop 47 is also slidably engaged with the dovetail slot 46 of the housing member 32 and secured to the housing 30 and engaged with the retainer 44 for stably or solidly anchoring or securing the retainer 44 to the housing 30. The housing 30 further includes one or more projections or catches 48 extended therefrom and located close to or beside the dovetail slot 46 of the housing member 32 and the retainer 44.
  • An arm 52 is further provided and attached or coupled to each of the bladders 50 for depressing or compressing and expanding the bladders 50 respectively. The arms 52 each includes a middle portion attached or coupled to the bladders 50 respectively, and one end 53 hooked or pivotally coupled to the housing 30 with the retainers 44 (FIGS. 1-2, 4-5), for example, a roller or pivot pin 54 is attached to the one end 53 of each arm 52 for pivotally engaging with the retainer 44 and for pivotally coupling the one end 53 of each arm 52 to the housing member 32 of the housing 30, and each includes a magnet or magnetic member 55 attached thereto, such as attached to the other end 56 of the arm 52 for acting or operating with the electro-magnetic device 20. The catches 48 may be engaged with the one ends 53 of the arms 52 and/or the pivot pins 54 for anchoring or securing the arms 52 and/or the pivot pins 54 to the housing 30.
  • As best shown in FIGS. 1 and 4-5, the electro-magnetic device 20 is disposed and located close to or beside the magnetic members 55 of the arms 52, for generating electro-magnetic field or force to force or to move the magnetic members 55 toward each other and/or away from each other (FIG. 5) in order to actuate the arms 52 to depress or compress and expand the bladders 50 respectively, and thus to force the air or water or fluid or liquid to flow between the compartments 51 of the bladders 50 and/or the spaces 41 of the casings 40 and the chambers 35, 36, of the housing 30, or to pump the air or water or fluid or liquid to flow through the coupler 21 and the inlet ports 37 and into the upper chamber 35 of the housing 30, and/or to flow out of the lower chambers 36 of the housings 30 through the outlet ports 38 of the housings 30 and the other coupler 23.
  • Two check valves 60, 61 each includes a shank 62 extended therefrom for engaging through the casing 40 respectively, and each further includes a ratchet catch 63 provided on the shank 62, for engaging with the casing 40 and for anchoring or securing the check valves 60, 61 to the casing 40 and between the bladders 50 and the chambers 35, 36, of the housing 30 and/or of the casings 40 respectively. Each of the check valves 60, 61 includes a resilient blade 64 formed or provided on one end of the shank 62 for selectively blocking or opening the orifices 42 or the apertures 43 of the housing 30 respectively in order to control the flowing of the air or water or fluid or liquid between the compartments 51 of the bladders 50 and/or the spaces 41 of the casings 40 and the chambers 35, 36 of the housing 30.
  • For example, when the magnetic members 55 are forced or moved toward each other or when the bladders 50 are expanded by the arms 52, the check valves 60 may be opened by the bladders 50 (FIG. 4) to allow the air or water or fluid or liquid to be drawn form the upper chamber 35 of the housing 30 into the space 41 of the casing 40 and the compartment 51 of the bladder 50, and to allow the air or water or fluid or liquid to be drawn through the coupler 21 and the inlet ports 37 of the housing 30 and then to be drawn into the upper chamber 35 of the housing 30. At this moment, the other check valve 61 will be forced to block the apertures 43 of the housing 30 (FIG. 6) by the bladder 50 to prevent the fluid or liquid from flowing backward form the lower chamber 36 of the housing 30 toward the compartment 51 of the bladder 50, and thus to allow the fluid or liquid to be drawn from the upper chamber 35 of the housing 30 into the compartment 51 of the bladder 50 only.
  • On the contrary, as shown in FIG. 5, when the magnetic members 55 are forced or moved away from each other by the electro-magnetic device 20, the bladders 50 may be depressed or compressed by the arms 52, and the other check valve 61 may be opened by the bladder 50 to allow the fluid or liquid to be forced to flow form the compartment 51 of the bladder 50 toward or into the lower chamber 36 of the housing 30 and then to allow the fluid or liquid to flow out of the housing 30 through the outlet ports 38 of the housing 30 or the other coupler 23. At this moment, the check valve 60 will be forced to close the upper chamber 35 of the housing 30 (FIG. 7) and to prevent the fluid or liquid from flowing backward form the compartment 51 of the bladder 50 into the upper chamber 35 of the housing 30.
  • In operation, the fluid or liquid may be drawn to flow into the upper chamber 35 of the housing 30 through the inlet port 37 of the housing 30 (FIGS. 4, 6), and then to flow form the upper chamber 35 of the housing 30 into the compartment 51 of the bladder 50 when the bladders 50 are expanded in the configuration or arrangement as shown in FIGS. 4, 6. The fluid or liquid may then be forced to flow form the compartment 51 of the bladder 50 into the lower chamber 36 of the housing 30 and then to flow out through the outlet port 38 of the housing 30 when the bladders 50 are depressed or compressed by the arm 52, such that the fluid or liquid may be pumped to flow into the inlet port 37 of the housing 30 and then to flow out of the inlet port 38 of the housing 30 by the bladders 50 step by step.
  • The arms 52 and the magnetic member 55 and the electro-magnetic device 20 may thus be formed as an actuating means or device for depressing or compressing or pumping the bladders 50 to draw the fluid or liquid or air into the upper chamber 35 of the housing 30 through the inlet port 37 of the housing 30, and then to force the fluid or liquid to flow into the other or lower chamber 36 of the housing 30, and then to force the fluid or liquid to flow out through the outlet port 38 of the housing 30. The magnetic member 55 and the electro-magnetic device 20 may thus be formed as an operating means or device for actuating or operating the arms 52 to depress or compress or pump or to expand the bladders 50 and to pump the fluid or liquid to flow into the inlet port 37 of the housing 30 and to flow out through the outlet port 38 of the housing 30.
  • As shown in FIGS. 3-5, the housing 30 may further include one or more protrusions or projections 49 extended into each of the chambers 35, 36 of the housing 30 for interfering the flowing of the fluid or liquid and for generating an eddy current for the fluid or liquid. Again, it is to be noted and emphasized that the outlet port 38 is formed or provided on the lower portion of the housing 30 such that the fluid or liquid received in the lower chamber 36 of the housing 30 may be effectively and completely forced to flow out of the lower chamber 36 of the housing 30 and to flow out through the outlet port 38 of the housing 30.
  • Alternatively, as shown in FIGS. 8-13, the diaphragm pumping device 301 may include two housing members 321 attached or secured together and arranged to have the upper chambers 35 of the housing members 321 communicated with each other, and also arranged to have the lower chambers 36 of the housing members 321 communicated with each other, and the bladders 50 are also attached to the casings 40 respectively and engaged with the arms 52 and arranged to have the bladders 50 to be compressed by the arms 52 in order to pump the fluid or liquid to flow into the inlet port 37 of the housing members 321 and to flow out through the outlet port 38 of the housing members 321. The retainer 441 may be solidly anchored or secured to or formed integral with the housing 30.
  • Further alternatively, as shown in FIGS. 14-16, the diaphragm pumping device 302 may also include two housing members 322 attached or secured together and arranged to have the upper chambers 35 of the housing members 322 communicated with each other, and also arranged to have the lower chambers 36 of the housing members 322 communicated with each other, and the bladders 50 are also attached to the casings 40 respectively and engaged with the arms 52 and arranged to have the bladders 50 to be compressed by the arms 52 in order to pump the fluid or liquid to flow into the inlet port 37 of the housing members 322 and to flow out through the outlet port 38 of the housing members 322. The retainer 44 may also include a dovetail member 45 slidably engaged in the dovetail slot 46 of the housing members 322, and a latch or stop 47 is also slidably engaged with the dovetail slot 46 of the housing member 322 and engaged with the retainer 44 for stably or solidly anchoring or securing the retainer 44 to the housing 30.
  • Accordingly, the diaphragm pumping device in accordance with the present invention may be actuated or operated by an electric actuating device, and may be used for vacuuming or air pumping purposes and for allowing the fluid to be effectively pumped.
  • Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
