Abstract

<P>PROBLEM TO BE SOLVED: To provide a foot-operated type air venting and filling machine capable of dispensing with electric power supply and continuously filling air and venting air. <P>SOLUTION: A foot plate 2 is pivotally fitted to a support frame 11 and two pusher pivot sections 22 are provided on the bottom of the foot plate. Two pumps 3 are in a main body, check valves 32 juxtaposed in opposite directions are on the bottoms of the respective pumps and air vents 320 are provided in their bottoms. Check valves corresponding to an intake pipe 33 and an exhaust pipe 34 are provided below the respective pumps, are brought into communication between two intake pipes via an intake branch pipe 35 and are brought into communication between two exhaust pipes via an exhaust branch pipe 36. An intake outer pipe 4 is connected to the intake branch pipe and an air filling outer pipe 5 is connected to the exhaust branch pipe. By stepping on the foot plate, opposite ends vertically oscillate about an axis of the portion where the foot plate and the support frame of the main body are pivoted and at the same time pistons in the two pumps are cooperatively moved and vertically operate in an alternative manner.

Description

The present invention relates to a stepping type air vent filling machine, and more particularly to a stepping type air vent filling machine that is continuously applied to air filling and air venting.

In general, items that require air filling are, for example, float bags, air filling pads, tires, balloons, air-filled infant water play pools, and other spheres, and most of them are air pumps to supply air. It is necessary to fill, and conventional air filling devices cannot be used for air bleeding because only air is filled into things and cannot be sucked, and general air bleeding devices (for example, food) Vacuum devices, milking machines, or suction devices for maintaining the freshness of foods, etc., require a power source, and devices that do not require a power source cannot provide a continuous and stable air venting force and are used outdoors. However, it is inconvenient, and only one function can be realized, but it is not possible to achieve both air bleeding and air filling. Therefore, the user purchases the air filling equipment, fills it with air, Kinds of products In response, you must purchase an air bleeder and not only take extra money, but also take up space for its storage and if you do not store it properly, Therefore, the existing ones are not practical.

A main object of the present invention is to provide a stepping type air vent filling machine that does not require a power source and can continuously perform air filling and air venting.

The main feature of the present invention is that there is a main body provided with a support frame having a pivot portion in the upper center, a pivot pivotally attached to the upper portion of the main body and pivotally attached to the pivot portion of the support frame of the main body, and The foot plate has two pusher pivots on the bottom, and is installed in the main body. There is a pivot that is pivotally attached to the landing part, and on the bottom surface, two Chuc valves that are arranged in parallel in the opposite direction are provided, and an intake pipe and an exhaust pipe corresponding to the Chuck valve are provided below, respectively. The two intake pipes are connected by an intake branch pipe, the two exhaust pipes are connected by an exhaust branch pipe, the intake outer pipe connected to the pump intake branch pipe, and the pump Connect to exhaust branch pipe An air-filled outer tube being, is contained.

Hereinafter, the above-mentioned objects and effects of the present invention and the technical means employed will be described in detail with reference to the drawings by giving better examples.

With reference to FIG. 1 and FIG.
A main body 1 provided with a support frame 11 having a pivot 110 in the upper center;
There is a foot plate 2 that is pivotally mounted above the main body 1, has a pivot 21 that is pivotally mounted on the pivot 110 of the support frame 11 of the main body 1, and two pusher pivots 22 on the bottom. ,
Both are installed in the main body 2 and have a piston 31. The piston 31 is provided with a pusher 310 exposed from the main body 1. The pusher 310 is pivotally attached to the pusher pivoting portion 22 on the bottom surface of the footboard 2. There are two pivot valves 311 that are arranged in parallel in the opposite direction on the bottom surface, and a vent hole 320 is provided on the bottom surface of each check valve 32. 321 is covered, and on the bottom surface, the intake pipe 33 extends below the Chuc valve 32 installed in the forward direction, corresponding to the vent hole 320, and is installed in the reverse direction on the bottom surface. The exhaust pipe 34 extends to the other end of one end facing the vent hole 320 of the Chuck valve 32, and the two intake pipes 33 are communicated with each other by the intake branch pipe 35 in the main body 1. The two exhaust pipes 34 is, the two pumps 3 to be communicated by the exhaust branch pipe 36,
An intake outer pipe 4 connected to an intake branch pipe 35 of the pump 3;
An air-filled outer pipe 5 connected to the exhaust branch pipe 36 of the pump 3;
Is contained.

With the above structure, both ends of the foot plate 2 can be swung up and down around the part where the foot plate 2 and the main body 1 support frame 11 are pivotally attached. Stepping back and forth, the footboard 2 swings around the pivoted part, and while swinging, the pistons 31 in the two pumps 3 are interlocked to swing up and down alternately. By installing the valve 32, it is possible to continuously perform air bleeding or air filling.

3 and FIG. 4, first, the suction nozzle A is fitted to the outer end of the intake outer pipe 4, and the suction nozzle A is set as the target of air bleeding (for example, a nasal aspirator). And suction devices, bowls with suction cups, breast augmenters, food preservation air vent cylinders, etc., and stepping on the foot plate 2, the foot plate 2 is shaken, and at the same time, the pistons 31 in the two pumps 3 are The pusher 310 and the piston 31 on the bottom surface are pulled up by one side (for example, a part of the foot or the heel) of the footboard 2 due to the rocking motion. In the intake state, the pusher 310 is interlocked with the footboard 2 and pulled up, and at the same time, the piston 31 is displaced upward. The valve piece 321 in the valve 32 is opened and empty. But it is sucked from the intake pipe 33 connected to the suction nozzle A of the outer end of the intake outer tube 4, that is, inspiration occurs, and by suction attraction, runny nose and phlegm, or milk, and the like are aspirated. As described above, when the user simply steps on the foot plate 2, the two pumps 3 are alternately operated to continuously release the air using the intake outer pipe 4. The effect is improved.

At the time of air filling, as shown in FIG. 5 and FIG. 6, first, the nozzle B is fitted on the outer end of the air filling outer tube 5, and the nozzle B is placed in the air filling target (for example, a floating bag or air filling It is inserted into the air filling port of a toy, a stepping wheel (tire), a ball, a life buoy, an inflatable boat, etc.). Similarly, when the stepping plate 2 is stepped on, the two pumps 3 The inner piston 31 is interlocked to operate up and down alternately, and the one side (for example, the heel portion) on which the swinging footboard 2 is displaced downward, the pusher 310 on the bottom surface and the piston 31 are interlocked. As a result, the air in the pump 3 is sent from the vent hole 320 to the exhaust pipe 34 by pushing the valve piece 321, and the user's foot (for example, a palm part) is Step 2 and when the other side is pushed down, the bottom The pusher 310 and the piston 31 of the other pump 3 are pushed down, so that air is pushed out of the exhaust pipe 34, so that air is continuously passed through the air-filled outer pipe 5 by alternating operation. Thus, the air filling object is filled, and the speed and effect of air filling are improved.

As such, the present invention is more progressive and more practical, and claims are filed according to law.

The above is merely a better embodiment of the present invention, and the present invention is not limited thereby. All modifications are within the scope of the claims of the present invention.
