Description

/ 6 “CONSTRUCTIVE ARRANGEMENT APPLIED IN A PRESSURE CHAMBER FOR SHOWERS”. TECHNICAL FIELD

[001] This utility model patent application pertains to the segment of electro-hydraulic equipment used in electric showers, specifically a pressure chamber that, together with the pressure switch, controls the operation of the electrical circuit according to the pressure in the hydraulic network. This spring-loaded mechanism activates or deactivates the component between the connection points. This results in energy and water savings for the user, as well as preventing the heating element from operating without water in the shower, thus preventing component burnout and potential risks of electric shock. HISTORY OF THE TECHNIQUE

[002] During the Industrial Revolution (18th and 19th centuries), many steam-powered machines and mechanical systems emerged to perform specific tasks, such as looms, engines, and production lines. However, these systems depended on human operators for control, which limited precision and efficiency.

[003] The advancement of electrical technologies, such as electric motors, brought new possibilities. The introduction of devices such as relays, switches, and transformers allowed for more effective control of mechanical systems. Combining electricity with mechanics, the first electromechanical systems emerged and began to be used to control motors, elevators, and production lines. In transportation, they were applied to trains, subways, and vehicles.

[004] The introduction of electromagnetic relays made it possible to implement simple control logic, giving rise to the first programmable logic controllers. These systems used relay circuits to perform functions such as timing, counting, and decision-making. Petition 870240108984, dated 12 / 20 / 2024, page 5 / 18 / 6

[005] With the advancement of electronic components, such as thermionic valves, transistors, and integrated circuits (from the mid-20th century onwards), control systems began to migrate to electronics, making electromechanical systems obsolete in many areas. Despite this, electromechanical devices are still used in specific applications. State of the Art Analysis

[006] Research conducted in specialized databases revealed documents relating to pressure switches, such as document no. BR 102019027195-7, which deals with a "FAST-ACTING PRESSURE SWITCH". The present invention relates to a pressure switch capable of rapidly alternating between the activation and deactivation positions. Said pressure switch comprises a blade system, a moving system, and an electrical contact system, which, associated with resilient elements, ensure speed and efficiency in the movement of the pressure switch. In this way, the pressure switch is able to prevent the formation of electrical arcs during the opening and closing of the circuit.

[007] Document no. PI 0903735-7 which deals with a “CONSTRUCTIVE ARRANGEMENT INTRODUCED IN PRESSURE SWITCH”, consisting of a base(2) composed centrally of a pressure pin(3), and laterally to said pin(3) there are caps(4) above the caps(4) the bars(5) are superimposed, which superiorly have a pair of poles(6) arranged distally, and the lower central portion has a recess(7) of integral conformation to the caps(4), in order to enable the semi-universal articular movement of said bars(5) and, consequently, of the poles(6), making the contacts, for the formation of the electrical bridge, act in a perfectly effective manner, fully compensating the varied inclined movements of the diaphragm(6) when actuated by the hydraulic pressure of the network.

[008] Document No. PI 9501803-4, which deals with a "MECHANICAL PRESSURE SWITCH", is a patent for invention of a mechanical pressure switch comprising a cast bronze piece (type T, altered in its internal geometry with a rectified seat in order to seal Petition 870240108984, dated 12 / 20 / 2024, page 6 / 18 / 6 compressed air passage, adapted with a bronze cylinder, piston and pressure spring in order to regulate differential pressure. It also includes a canopy, which serves to retain the compressed air at a minimum pressure level, and a pressure variator composed of a diaphragm and spiral spring that relieves the compressor's intake valves at a maximum pressure level.

[009] Through patent analysis, it is possible to identify documents that mention devices in the same field of activity, which perform their functions, but still present some limitations. In some cases, lack of pressure in the hydraulic network, diaphragm wear, or the presence of particles resulting from pipe rusting can cause clogging of the mechanism. Furthermore, the models mentioned do not present effective solutions to control possible leak points, which compromises the functioning of the shower as a whole, considering the inventive act in relation to the prior art found in the state of the art.

[010] Thus, it is a fact that the documents cited in the paragraphs above, despite belonging to the same field of application, do not present any of the characteristics of the object now improved, thus guaranteeing that it meets the legal requirements for patentability. BRIEF DESCRIPTION

[011] Taking into account all the problems that have been presented in the state of the art, the inventor, who has notorious knowledge of the sector, created and developed the aforementioned “CONSTRUCTIVE ARRANGEMENT APPLIED IN PRESSURE CHAMBER FOR SHOWERS”, which aims to control the operation of the electrical circuit according to the pressure in the hydraulic network.

[012] The objective of the present utility model is to present a spring mechanism that regulates the minimum pressure required for operation, activating or deactivating the component between the connection points, with the aid of a rubber membrane. All connections are equipped with rubber sealing rings, Petition 870240108984, dated 12 / 20 / 2024, page 7 / 18 / 6 preventing water leakage from different points. This mechanism assists in the shower's operation, preventing the heating element from burning out, since the electrical circuit will only be activated when water passes through with the established minimum pressure. This provides benefits such as energy savings and reduced equipment maintenance needs. This mechanism is compatible with different shower models that have a pressure switch to control their electrical circuit.

[013] The present utility model takes into account not only the mechanical and functional qualities, but also the form, arrangement and strategic location of its parts and components which, correctly positioned, brought about an increase in efficiency without incurring any burden on the users.
