Abstract

(57) [Summary] [Purpose] To provide a foot-operated tubing pump that is useful for supplying water from rivers, ponds, rainwater, pools, etc. as drinking water sources to water purifiers in the event of a disaster, drought, or camping. is there. [Structure] A special huge tube of the same material as that of a conventional blood pump and having a large diameter and a large thickness is formed to be a main body 1 of a tubing pump, and simple check valves 2 and 2'are provided at both ends of the cores 3 and 3, respectively. It is a foot pump that is inserted together with the suction hose 4 and connected to the suction hose 4 and the outlet hose 5.

[Industrial applications]

 The present invention provides a foot-operated tubing pump useful for supplying water from rivers, ponds, rainwater, pools, etc. as a drinking water source in the event of a disaster, drought, or camping.

[0002]

[Prior art]

 The interruption of power outages causes anxiety and confusion in many residents in the event of a disaster, and the recent Hanshin earthquake is a prominent example. In such cases, it is simple, but it is desirable to be able to drink raw water with peace of mind. However, in the past, the amount of water to be sent was extremely small or the user was very tired due to the use of a camping pump or hand pump composed of an extremely small filter cylinder and bellows hand pump.

[0003]

[Problems to be solved by the device]

 Therefore, if a water purifier that uses 100% sterilization by simply passing water and that is completely harmless to humans and animals can be made, it is possible to drink raw water without anxiety. Came to solve this point by using a water purifier separately filed at the same time as this application. Further, the applicant has come to think that it is extremely effective to introduce a simple pump device into the water purifier to guide river water, muddy water in a pond, etc. without the user getting tired.

[0004]

[Means for Solving the Problems]

 In consideration of these points, the present inventor has conducted various experiments and trial productions, and as a result, the tube of the blood pump conventionally used for medical treatment has extremely excellent resilience, softness, and impact resistance. In light of this, he came up with the idea of expanding this and using it as the main body of the pump and succeeded.

[0005]

[Effect] Thus, in the present invention, by making the diameter of the soft tube used for the blood pump tube large, for example, about 40 to 50 mm, and making it durable with a thickness of about 5 mm, the durability is improved. In addition, it was possible to prove that it can withstand practical use as a foot-operated tubing pump with extremely excellent resilience. Although the principle is a simple old-fashioned method, it was experimentally proved that the use of this material produced unprecedented durability and high performance. It should be noted that the tube material includes all materials that can utilize the restoring property as long as they comply with this principle.

【Example】

 FIG. 1 is a side sectional view of a tubing pump according to the present invention, in which 1 is a tube which is the main body of the tubing pump, and 1'shows the position as the amount of change in one step, and this tube is used by a person. The pump function is exerted by repeatedly stepping on and loosening one foot at the center of step 1. Therefore, a foot pedal that is the most powerful in human function and that does not cause tiredness only by riding is extremely effective. In order to exert the pumping function, the simple check valves 2, 2'and the core 3 are respectively provided at the connection part on the suction hose 4 side at the inlet of the tubing pump 1 and the connection part on the hose 5 side connected to the water purifier 6 at the outlet. , 3'is provided, and when stepping on, the ball 2a of the valve 2 pushes the inlet that was blocking the inlet by the suction force, opens the water and sucks the water into the tubing pump 1, and then the outlet side of the tubing pump 1 The ball 2'a of the valve 2'is pushed open and the water in the tubing pump is sent to the water purifier 6 through the outlet hose 5, and the amount of water indicated by the diagonal lines in Fig. 2 is fed to the outlet hose 3 with one step. Therefore, if the foot is separated from the tubing pump 1, the check valve 2'will block the outlet and the water once sent will not return. At the same time, the check valve 2 is opened by the internal negative pressure generated by the restoring force of the tubing pump 1, and new water is introduced from the inlet.

FIG. 2 shows a simplified diagram of the case where the tubing pump 1 of the present invention is used to send water from a pond, river, etc. 7 to a water purifier 6 and to use it as sterile, odorless water taken out from an extraction pipe 8 and used as drinking water. The shaded portion of the tubing pump 1 corresponds to the amount of water sent from the tubing pump 1 in one step, 4 is a suction hose, 5 is a tubing pump outlet hose, and 6 is a water purifier. For example, it was possible to deliver approximately 4 liters of water per minute with 150 cc per step of the prototype pump.

[0008]

[Effect of device]

 Thus, since the tubing pump 1 of the present invention can be easily and easily operated by stepping on, it can be easily handled by a woman or a child. You can get water.
