Description

Electronically ventilated plunger:

A so-called plunger is a suction bell, i.e. a drain or pipe cleaner, consisting of a suction rubber in the shape of a bell that is attached to a handle with which the plunger is operated. Plungers are available in various sizes, although the basic shape described is the same. A plunger is usually made from commercially available materials, i.e. the suction bell is made of rubber and the handle is made of wood or plastic.

The plunger is primarily used as a drain and pipe cleaner by pressing the suction cup onto the drain and the resulting negative pressure under the cup sucks air out of the drain or pipe and in this way sucks out any clogging materials in the drain.

The invention specified in the claims is based on the problem that a plunger gets stuck on a smooth surface when the rubber of the plunger is pressed onto a smooth surface, because a vacuum is created in the rubber bell. The plunger can then only be released if air

gets under the rubber bell. Due to material-related circumstances with a commercial plunger, air only gets under the rubber very slowly, which means that the plunger can only be removed from a smooth surface very slowly.

With the invention of the electronic plunger, the rubber can be loosened in seconds by opening and closing an electronically operated solenoid valve, allowing air to flow under the rubber.

The solenoid valve in the electronically ventilated plunger is operated by a radio transmitter that controls when air is let under the rubber cap. The radio transmitter sends a coded radio signal, which in turn is received by the receiver electronics in the plunger. The radio transmitter is a standard handheld transmitter that is worn on the wrist of the plunger operator. The radio signal is triggered by a button on the transmitter.

button. Automatic activation using a timer is also possible.

If such an electronically ventilated plunger gets stuck on a smooth surface, the plunger can be quickly released in this way.

The attached drawing shows the shape of a standard plunger with the design of the electronically ventilated plunger. The suction rubber (6) is attached to the hollow handle that can be screwed on at the top (1). Above the rubber in the handle is the valve (4) with a ventilation hole (5) and a metal tip (7) that protrudes into the rubber and above the valve are batteries (3) and radio electronics (2).

Claims (1)

Protection claims Electronically ventilated plunger, consisting of a rubber suction cup attached to a handle made of commercially available materials, which is characterized by that the handle of the electronically ventilated plunger is hollow and in the handle above the rubber suction cup there is a magnetic valve (4) whose metal tip (7) extends into the rubber suction cup. This valve has a ventilation hole (5) on the side of the handle, which is normally closed. The valve is opened and closed by means of the electronics for a radio receiver (2), which is also housed in the handle and which draws its power from two batteries (3) also located in the handle. The electronics and the batteries can be accessed through a screw cap (1). The electronically ventilated plunger is further characterized by the fact that the magnetic valve (4) is closed in the rest position, but opens in response to a radio signal from the operator, thereby sucking in some air through the ventilation hole (5) and guiding it under the rubber (6). Shortly after the radio signal is activated, the electronics close the magnetic valve again and return to the rest position. As air flows through the rubber in this way, the plunger detaches from the respective surface. t;·
