Description

Pumping Apparatus using Hand Pump}

The present invention (Disclosure) relates to a pumping device using a manual pump. Specifically, by combining a water tank and a manual pump that can always supply water using a water supply facility, manpower is used even in places where there is no groundwater. It relates to a pumping device using a manual pump capable of pumping operation with a manual pump and supplying water at all times from a water supply facility.

Here, background technology related to the present invention is provided, and these do not necessarily mean known technology (This section provides background information related to the present disclosure which is not necessarily prior art).

The manual pump, also known as the small head pump, is similar in principle to the syringe.

By repeating the operation of lowering the pressure of the suction pipe as the piston moves vertically and reciprocating inside the body that is erected in the vertical direction and functions as a cylinder, the suction pipe immersed groundwater is eluted to the ground.

The user moves the piston up and down using a lever.

These hand pumps were used in times when water supply was not available or in small residential areas far from populated areas.

As water supply facilities are spreading to almost all residential areas, manual pumps that use manpower have almost disappeared in modern real life. In particular, since it is necessary to use groundwater, there is a problem that it is difficult to use it in real life, not only in urban areas but also in rural areas.

As such, manual pumps, which have disappeared due to convenience or installation problems, are increasingly being used as outdoor landscaping materials for gardens.

Even people who have never actually used a manual pump are getting the spotlight as a new vintage landscape, because they can see how to use it at least once through various video media.

However, if the manual pump installed for landscaping is actually operable, it can induce fun and curiosity to people in addition to simple aesthetics.

In other words, the interior effect of the manual pump itself is provided with an actual pumping function, adding a dynamic feeling, and furthermore, by installing it as a means of discharging the water supply line that can be used at all times, it can be experienced without staying with the eyes. It can be used as a landscaping prop.

In addition, since it is easy to understand the operating principle of a manual pump that is not currently used, it can be used as an educational prop.

It is revealed that the embodiment described in the above is encompassed by a range that can be easily proposed by a method of substitution or modification.

In addition, since the terms used below are selected for convenience of description, in grasping the intrinsic technical idea of the present invention, it is not limited to the dictionary meaning and is appropriately interpreted as a meaning consistent with the technical idea of the present invention. It should be.

FIG. 1 is a view showing a first embodiment of a pumping device using a manual pump according to the present invention, and FIG. 2 is an enlarged view of area A in FIG. 1.

1 to 2, a pumping device using a manual pump according to the present embodiment includes a water tank 200, a manual pump 100, and a pumping aid 400.

The water tank 200 accommodates water and supplies water to a manual pump 100 to be described later.

The manual pump 100 has a body 110, a suction pipe 130, a discharge pipe 150, a lever 120, a piston 160, and a flow valve 140.

The body 110 has a hollow cylinder space (a1) therein.

The suction pipe 130 is formed to extend downwardly under the body 110 and the lower end is immersed under the water surface of the water accommodated in the water tank 200.

The water discharge pipe 150 is formed extending laterally from the upper side of the body 110, and water pumped through the suction pipe 130 and the cylinder space a1 is discharged.

The lever 120 is installed on the other side of the upper body 110.

The piston 160 vertically moves the cylinder space a1 inside the body 110 according to the repeated pumping operation of the lever 120.

Therefore, of course, the lever 120 and the piston 160 are fastened with a connecting means 121 including a hinge means.

The flow valve 140 is opened and closed so that water flows only upward from the suction pipe 130 to the discharge pipe 150 through the cylinder space a1 according to the upward movement of the piston 160.

The flow valve 140 is preferably configured to include a piston valve 141 formed on the piston 160 and a body valve 142 formed between the body 110 and the suction pipe 130.

The pumping auxiliary device 400 is installed on the suction pipe 130 and includes a pumping auxiliary body 401 and a pumping auxiliary valve 410 having a hollow pumping auxiliary space a2 therein.

The pumping auxiliary valve 410 is opened and closed so that water flows upward only from the suction pipe 130 to the body 110 through the pumping auxiliary space a2 according to the upward movement of the piston 160.

The pumping auxiliary valve 410 is preferably in a T-shape, and the lower protrusion penetrates through the valve holder 420 to be described later in the downward direction.

At this time, the pumping aid 400, a valve flange 430 protruding from the inner surface of the pumping auxiliary body 401 and a valve holder protruding from the inner surface of the pumping auxiliary body 401 below the valve flange 430 ( 420).

The flow valve 140 and the pumping auxiliary valve 410 have in common that water flows only upward and opens and closes so that water does not flow downward.

Accordingly, the pumping device using the manual pump according to the present embodiment has an improved pumping height h2 by effectively reducing the conventional pumping height h1 of the conventional manual pump.

The conventional pumping height h1 corresponds to the lower end of the body 110 from the water surface of the water tank 200, and the piston 160 must be moved up and down several times using the lever 120.

In a conventional manual pump, when the piston 160 rises, the piston valve 141 is closed and the body valve 142 is opened upward, so that the air pressure inside the cylinder space a1 and the suction pipe 130 is external air pressure. Lower than. Water rises into the suction pipe 130 by the difference between the lowered air pressure and the external air pressure.

This is repeated several times and finally, through the suction pipe 130 and the cylinder space a1, the piston 160 is pumped upward through the piston valve 141, and is eventually discharged to the water discharge pipe 150.

Meanwhile, while the piston 160 descends, the body valve 142 is closed, so that when the piston 160 rises, the water level of the raised water can be maintained.

However, in order to maintain the water level at this time, two requirements are required.

First, the sealing force of the body valve 142 must be complete, and second, the self-weight of water as high as the water level must be smaller than the force that the external air pressure pressurizes the water surface.

However, the sealing force of the body valve 142 may not be complete.

In addition, since the conventional pumping height h1 is higher than the improved pumping height h2, the pressure loss generated during repeated vertical movement of the actual piston 160 increases, and thus, the conventional pumping height h1 is increased. The pumping operation not only increases the number of pumping operations of the lever, but also has a difficulty in repeating the pumping operation of the lever 120 at a high speed.

In contrast, the pumping device using a manual pump according to the present invention provides an improved pumping height of the water pumped through the suction pipe 130 by forming a pumping aid 400 having a pumping auxiliary space on the suction pipe 130. Decrease it to the height (h2).

The water that has risen to the pumping auxiliary device 400 and the pumping auxiliary space a2 does not flow downward by the pumping auxiliary valve 410.

Accordingly, the actual pumping height has an effect of effectively reducing the conventional pumping height h1 to an improved pumping height h2.

In addition, the body valve 142 and the pumping auxiliary valve 410 have the effect of increasing the sealing force due to the pressure of the water pumped to the upper side.

In the conventional manual pump having one body valve 142, if the body valve 142 is not completely sealed, the water pumped upwardly leaks and goes down to the water tank 200 again.

Accordingly, in order to pump water from the water tank again, there is a problem in that water must be pumped again as much as the conventional pumping height h1.

However, in the pumping device using the manual pump according to the present embodiment, the water leaked from the body valve 142 does not flow downward by the pumping auxiliary valve 410 again and is accommodated in the pumping auxiliary space a2.

In particular, since the amount of water pumped upward of the pumping auxiliary valve 410 includes the amount of water pumped upward of the body valve 142, the sealing force of the pumping auxiliary valve 410 is greater than the sealing force of the body valve 142.

Therefore, it is possible to prevent the water level once pumped from falling, thereby providing convenience to the operation of the manual pump.

In addition, the pumping device using the manual pump according to the present embodiment may further include a water supply unit 300 for supplying water to the water tank 200 from a water supply pipe.

The water supply unit 300 may include a water supply pipe 320 supplying water into the water tank 200 and a water supply control unit 310 connecting and opening and closing the water supply pipe 10 and the water supply pipe 320.

Accordingly, the pumping device using the manual pump according to the present embodiment can use the manual pump 100 at all times, and can be installed in a place where a water supply pipe is formed, regardless of the presence of groundwater.

In addition, the pumping device using the manual pump according to the present embodiment further includes a water level sensor 330 for sensing the level of water contained in the water tank 200, and the water supply control unit 310 described above includes a water level sensor 330 The operation of the water supply unit 300 can be automatically controlled according to the measured water level.

Accordingly, the water level of water accommodated in the water tank 200 can be kept constant. In addition, by keeping the water level of the water tank 200 constant, the improved pumping height h2 by the above-described pumping aid 400 can be kept constant.

The water supply pipe 320 is connected adjacent to the bottom surface of the water tank 200 so that when water is supplied through the water supply pipe 10, the sound of water falling inside the water tank 200 does not occur.

The sound of water falling may itself be a noise, and the sound may be greatly amplified by resonating inside the water tank 200.

In particular, when the water level in the water tank 200 is lowered by operating the manual pump 100 to pump water inside the water tank 200, and when water is supplied through the water supply pipe 10, as described above. In the case of noise, it reduces the vintage feeling that the user uses the manual pump 100 by half.

Therefore, by connecting the water supply pipe 320 adjacent to the bottom of the water tank 200, it is possible not only to reduce noise, but also to reconsider the functionality as a "working landscape prop".

FIG. 3 is a view showing a second embodiment of a pumping device using a manual pump according to the present invention, and FIG. 4 is an enlarged view of area B in FIG. 3.

According to FIGS. 3 to 4, in the pumping device using a manual pump according to the present embodiment, the pumping aid 400 is an elastic member 440 disposed between the lower protrusion of the pumping auxiliary valve 410 and the valve holder 420 It has more.

The elastic member 440 strengthens the sealing force of the pumping auxiliary valve 410 by providing an elastic restoring force between the pumping auxiliary valve 410 and the valve holder.

Accordingly, the improved pumping height h2 described above can be maintained for a long time.

In addition, in the pumping device using a manual pump according to the present embodiment, the pumping aid 400 further includes a branch pipe 460 and a constant valve 450.

The branch pipe 460 is formed above the pumping auxiliary valve 410 and may supply water from the water supply pipe to the pumping auxiliary space. One end of the branch pipe 460 may be connected to the pumping auxiliary body 401 to be connected to the pumping auxiliary space a2, and the other end may be connected to the water supply pipe 10 or the water supply unit 300 described above.

In addition, the constant valve 450 may be formed in the branch pipe 460 to open and close the branch pipe.

Accordingly, the pumping device using the manual pump according to the present embodiment may be used as a water supply means of the water supply pipe 10 capable of supplying water supplied from the water supply pipe 10 according to the needs of the user.

When the user opens the water supply valve 450, water is supplied from the water supply pipe 10 or the water supply unit 300 to be supplied to the pumping auxiliary space a2.

Water supplied to the pumping auxiliary space a2 is not lost or leaked downward by the pumping auxiliary valve 410.

When the user keeps the water supply valve 450 open, the water supplied from the water supply pipe or the water supply unit 300 fills the pumping auxiliary space (a2), and then opens the body valve 142 with the pressure. To fill the cylinder space (a1).

The water filled in the cylinder space a1 opens the piston valve 141 again, and the water level continues to rise and is eventually discharged to the outside through the water discharge pipe 150.

The above-described process is the same as the operation of the body valve 142 and the piston valve 141 when the user operates the lever 120 of the manual pump 100 to pump water from the water tank 200.

Accordingly, the manual pump 100 functions as a water supply device for supplying water supplied from a water supply line.

In addition, in a state where the upper side of the cylinder space (a1), the pumping auxiliary space (a2), and the piston 160 is filled with water by opening the constant valve 450, the water tank ( It also has the effect of pumping water of 200).

In conclusion, in the pumping device using the manual pump according to the present embodiment, the user can selectively use the manual pump 100 and the water supply pipe 10 operated by manpower.

In addition, when the water supplied from the water supply pipe 10 is supplied and used, the manual pump 100 that does not require a pick-up water can be operated, thereby providing convenience in use of the manual pump 100.

In another embodiment of the pumping device using a manual pump according to the present embodiment, the body 110, the suction pipe 130, and the pumping aid 400 are coupled to be detachable from each other.

Accordingly, by individually manufacturing the body 110, the suction pipe 130, and the pumping aid 400, it is easy to assemble and disassemble.

In particular, since the body 110, the suction pipe 130, and the pumping aid 400 are disassembled from each other, all of them can be packaged in a single package, so that long distance delivery is easy.

In addition, as described above, the body 110, the suction pipe 130, and the pumping aid 400 may be disassembled and accommodated in the water tank 200. Accordingly, it is easy to load in the process of moving the logistics and reduce the loss of the moving space, thereby minimizing the logistics cost.
