AI Technical Summary

Benefits of technology

"The present invention relates to improved plungers for unclogging clogged drainpipes. The inventor has discovered that standard plungers can only push and pull the clog in the same area, without dislodging it. The inventor has invented plungers with a head and a one-way valve that allows fluid to flow in one direction and inhibits it in the other. The plunger also includes a pressurizing mechanism that forces fluid to flow through the head. The plunger can be used alone or in combination with other plungers to increase fluid pressure within the conduit and maintain it after the force is released. The plunger kit includes a pressurizing mechanism and two heads that allow fluid to flow in opposite directions. The technical effects of the invention are improved plungers that can better dislodge clogs and increase fluid pressure within the conduit."

Problems solved by technology

This can increase the pressure in the drain (by pushing down) and / or decrease pressure in the drain (by pulling up), which may dislodge obstructions within the drain or attached drainpipes.

Embodiment Construction

[0017]Referring to FIG. 1, a plunger (100) can include a pressurizing mechanism (120), which can include a bellows (122) having a body (124), an air intake (126) at the top of the body (124), and an air exit (128) at the bottom of the body (124). The bellows (122) can be compressed to force air out of the body (124) or stretched to draw air into the body (124). For example, the bellows (122) may be a bellows that is similar to bellows used as heads for some current bellows plungers. For example, the bellows (122) may be formed of a flexible rubber or plastic material.

[0018]A handle (140) can extend down from the air exit (128) of the bellows (122). The handle (140) can be secured to the bellows (122) in any of various ways. For example, the handle (140) may include female threads that engage male threads on the air exit (128) of the bellows (122). The handle (140) can be a standard pipe, such as a pipe formed of polyvinyl chloride (PVC) or some other piping material. The handle (140...

Abstract

A plunger can include a head configured to engage an opening to a conduit. The plunger can also include a one-way valve that allows fluid flow through the head and out of the plunger, but that inhibits fluid flow through the head and into the plunger. The plunger can also include a pressurizing mechanism that forces fluid to flow through the head and out of the plunger. The mechanism can be detachable from the head. A head of a plunger can be positioned to engage an opening of an obstructed conduit. A force can be applied to the plunger, and the plunger can increase a fluid pressure within the conduit in response to the force. The force on the plunger can be released, and the plunger can maintain the fluid pressure within the conduit at an increased level after the force is released.

Description

BACKGROUND[0001]Plungers are often used to unclog conduits, such as drains and drainpipes for toilets, sinks, tubs, and showers. A standard plunger includes a head that includes a chamber that can be positioned in a drain, with the chamber opening into the drain. A plunger typically also includes a handle attached to the head. The handle can be pushed down make the chamber smaller and push liquid into the drain, and / or pulled up to make the chamber larger and pull liquid up from the drain. This can increase the pressure in the drain (by pushing down) and / or decrease pressure in the drain (by pulling up), which may dislodge obstructions within the drain or attached drainpipes.SUMMARY[0002]While standard plungers may unclog many clogged conduits, the present inventor has recognized drawbacks with standard plungers. For example, the inventor has found that with many standard plungers, the pushing and pulling action described above can merely push and pull the clog in and out of the sam...
