WATER PRESSURIZED MANUAL LAVATORY DE-BLOCKING MANUAL PUMP
Field of the Technique
This invention relates to a manual pump operated by water pressure, which is
specially designed to de-block the congestion in lavatories, tubs and kitchen
sinks
commonly available in houses, offices and all kinds of residences.
Infrastructure of the Invention
io The manual pump, which is the subject of the invention devised on the basis
of a
simple vacuum manual pump used when there is congestion in sinks in general,
has been re-designed in a manner rendering it more convenient, practical and
safer by addressing the negative aspects of presently available manual pumps
and lavatory de-blockers.
is It is common knowledge that various chemicals and vacuum manual pumps are
presently used to clean away waste sediments accumulating inside siphons as in
drain hoses and pipes. Use of chemicals to de-block congested lavatories
exposes
risks for health and besides, it leads to environmental pollution. Such
chemicals
are poured into siphons by adding hot water into them so that they are more
2o effective and toxic gases that may emit in such a situation pose high risks
in view
of the health of humans and creatures.
A simple vacuum manual pump is another popular method of de-blocking the
congested lavatories. By positioning the manual pump in a manner ensuring that
it
covers the mouth of the lavatory, vacuum is created by applying pressure from
25 above in an attempt to force blocking sediments inside siphon go down the
drain.
Dirt and sediments which cannot get out of drain come out of the holes on the
lavatory. During pump vacuum, there may be back pressure due to siphon wastes
and in such a situation, waste water may be splashed around making the clothes
of people nearby dirty, which is something no desired at all. That is why the
30 method of de-blocking congested siphons with chemicals is preferred in
houses.
Chemicals are not cheap products and their use should not be preferred or it
must

be minimum to the extent as may be necessary only as it poses high risks for
human health and causes environmental pollution.
The subject invention created by us, which is a manual pump, is a product
devised
to deal with all the negative aspects mentioned above and it is specially
designed
for this purpose; thus, any congested drains can be de-blocked by forcing down
sediments and wastes by using water pressure.
The most important feature of our invention is that wastes in siphons can be
removed by pushing them away with pressurized water in a manual pump only
without using any chemicals.
Explanation of the invention
The present invention has been designed to deal with the negative aspects
mentioned above and it is ultimately targeted to create an economical manual
pump, which is convenient for production and practical for use and capable of
removing wastes without requiring use of any chemicals.
Therefore, the objective of the present invention is its capability of
removing dirt
during daily use without having to use chemicals.
Another objective of the invention to prevent waste water splashes that take
place
during cleaning.
Development of an economical and practical product may be cited yet another
objective of the invention.
Yet another objective of the invention is to offer a product which protects
environment and human health and is therefore preferred.
For this purpose, the manual pump, which is the subject of the invention,
consists
of : a pump body (3), a valve body (8) positioned under this pump body (3),
valve
cover (7), valve cover spring (6) and impermeability gasket (5) and it is easy
to
produce and practical for use and quite an economical product.
The subject invention is illustrated by the following figures in further
detail.

The manual pump, which is the subject of the invention, incorporates: a pump
body (3) having a cylindrical structure of bellows, a round water filling
intake (1)
located on top of this pump body (3) and billow flaps on sides (4) and in
addition,
there are a valve body (8) positioned under this pump body (3) and a valve
cover
(7) mounted to this valve main body (8) as well as a round shaped rubber
impermeability gasket (5) providing impermeability by installing it between
this
valve body (8) and pump body (3) including a valve cover (7) and a valve cover
spring (6) located under the pump body (3).
The operational method of the pump is as follows: Water is filled into the
pump
body (3) from the water filling intake (1); the pump top cover (2) is placed
on the
pump body and then firmly positioned on the siphon stamps in the sinks and
lavatories; manual pressure is applied from top and the valve cover (7) is
opened
3o and during this operation, as the billow flaps (4) are under pressure, the
water
inside the pump body (3) penetrates inside from the lavatory intake with much
pressure and this pressurized water enables any deposits of dirt and sediment
to

flow down the drain hose and pipes. During this operation, the impermeability
gasket (5) prevents water from coming out of the location where the pump body
(3) joins the valve body (8) due to ensuing pressure.
