Description

Technical Field

[0001] This invention relates to the field of water control valve technology, specifically to a shallow-mounted fixing device for a foot-operated airbag switch for a pneumatic valve to dispense water. Background Technology

[0002] The most common foot-operated valves in existing technology are divided into hydraulic and mechanical linkage types. Although the exposed part of the foot pedal of a hydraulic valve is about 2 centimeters above the ground, the valve body itself is about 10 centimeters thick. This requires digging a pit up to 10 centimeters deep below the ground surface, which can easily damage the waterproofing layer of the floor slabs in kitchens, bathrooms, and shower rooms on different floors of a building. In addition, hydraulic valves require two copper pipes to introduce water into the valve under the foot, and then send it back to the faucet leading to the sink pipe. This kind of pre-installed, deeply buried installation will cause significant trouble for building maintenance.

[0003] Another type of foot-operated valve is the mechanical linkage valve, where the foot pedal linkage is integrated with the valve. A hole needs to be drilled in the ground to install the valve using expansion bolts. The foot pedal on this type of valve linkage needs to be tilted upwards, at least 10 centimeters above the ground. It also requires one inlet pipe and one outlet pipe. For the user, this involves a significant range of motion as they lift and press the pedal repeatedly, sacrificing user comfort to get water flowing. This method makes it difficult to achieve water conservation through frequent opening and closing.

[0004] Existing hydraulic or mechanically linked foot valves are designed and manufactured as a single unit, integrating the valve, pedal, and lever. This results in a large volume and a poor durability, with internal structures relying on a compression spring to activate a linkage rod that closes an internal rubber ring for water inflow and outflow. Typically, failure occurs within about a year due to mechanical wear and aging of the internal rubber ring. Hydraulic valves and pedals are often embedded in the interior finishes, leading to high construction and maintenance costs. Furthermore, both types of valves require the processing of copper and cast aluminum materials, resulting in high energy and material consumption, high production costs, and limited functionality.

[0005] In addition, existing foot valves are basically designed to control a single water supply, meaning one foot valve corresponds to one single faucet. Currently, dual hot and cold water faucets are quite common. If one foot valve is to control dual (hot and cold) water supply, four pipes must be installed between the foot valve and the faucet: one for cold water inlet, one for cold water return, one for hot water inlet, and one for hot water return. This would double the size of each part of such a foot valve, and the space required for renovation would also increase accordingly.

[0006] The above-mentioned problems urgently need to be addressed. Summary of the Invention

[0007] The present application provides a kind of aerodynamic valve water outlet's shallow installation type fixing device of foot gasbag switch, its purpose is to solve the technical problem of traditional foot valve pre-installation deep buried type decoration destruction waterproof layer, foot key installation position high user use operation is inconvenient, internal rubber ring aging mechanical hard wear is serious, cold and hot double faucet must one-to-one installation foot valve.

[0013] The aforementioned shallow-mounted fixing device for a foot-operated airbag switch for a pneumatic valve water outlet comprises an airbag 1 consisting of an upper hemispherical airbag 11 and a bottom circular plate-shaped airbag seat 12 sealed together, forming a hemispherical cavity inside. An exhaust pipe 13 is provided on one side of the airbag at the bottom, connecting to the interior of the airbag. The exhaust pipe is connected to the air inlet of the pneumatic valve 400 through an air inlet pipe. The airbag is a silicone airbag.

[0014] The aforementioned shallow-mounted fixing device for a foot pedal airbag switch for a pneumatic valve water outlet includes an exhaust pipe 13 connected to a microtube 131, the microtube connected to a tee, and the other two ends of the tee connected to the air inlets of two pneumatic valves respectively via two microtubes.

The bottom of the height-adjustable self-tapping screws 8 is supported on the ground within the circular recess.

[0017] The securing of the foot-operated airbag in this invention is particularly important. Typically, lowering the foot valve pedal's height from the ground by a few millimeters provides better user comfort. The airbag, U-shaped clip, and valve cover of this invention are fixed to the ground at a depth adapted to the thickness of the tile or wooden floor, without damaging the floor's waterproofing layer. The silicone airbag is a flexible, elastic material; the compressed gas generated by stepping on the airbag forms a closed loop to the pneumatic valve, allowing the sphere to automatically return to its original shape and withstand frequent pressure. The compressed gas generated by stepping on the airbag travels to the pneumatic valve via a conduit, which can control not only one pneumatic valve but also two pneumatic valves by using a three-way valve along the conduit. This invention uses only one airbag to control dual-valve water supply without increasing the airbag's volume. Because compressed air is routed through a micro-tube from the airbag to the pneumatic valve via a three-way valve, the airflow is distributed to both valves, allowing them to open and close simultaneously. The dual-water faucet on the sink allows the handles for adjusting hot and cold water to be positioned at a suitable temperature. The shallow-filled airbag assembly device of this invention can be easily disassembled and assembled like building blocks, and is miniaturized and can be plugged in. It saves labor and materials, as the required materials can be easily manufactured using injection molding, thus saving energy and protecting the environment while keeping the ground clean and aesthetically pleasing.

[0018] The beneficial effects of this invention are:

[0019] The invention is shallowly installed on the ground, does not destroy the waterproof layer of the floor, and only uses one air bag to control the double-valve water supply without increasing the volume of the air bag, and can be easily disassembled, miniaturized, and assembled in a plug-in manner like a building block toy, thereby saving labor and materials, and maintaining the neatness and beauty of the ground.
