Description

Technical Field

[0001] This utility model relates to the technical field of gas pressure regulators, specifically a timed pressure regulator with overcurrent cut-off function. Background Technology

[0002] A timer regulator in a gas supply system is a device used to regulate gas pressure. Its main function is to automatically adjust the gas flow rate to maintain the gas outlet pressure within a set range, thereby ensuring the stability and safety of the gas supply. A timer regulator with overcurrent cut-off function is a common safety device in gas appliances. Its main function is to automatically cut off the power supply when the detected current exceeds a set value, preventing equipment damage or safety accidents caused by excessive current. This device is commonly used in household or commercial gas appliances, especially in scenarios requiring high safety standards.

[0003] Existing timed voltage regulators with overcurrent cut-off function use a timer set at the outlet of the regulator to control the opening and closing of the outlet. If the regulator itself leaks, the timer's timed shutdown function will fail, causing the regulator to still leak. Utility Model Content

[0004] The purpose of this invention is to provide a timed voltage regulator with overcurrent cut-off function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A timed voltage regulator with overcurrent cut-off function includes a voltage regulator cover structure formed by assembling a lower housing and an upper housing, wherein the lower housing and the upper housing are detachably connected, a valve cavity is formed inside the voltage regulator cover structure, and a timer unit is installed inside the valve cavity; a voltage regulating motion unit is provided inside the valve cavity, and the voltage regulating motion unit includes;

[0007] A diaphragm is disposed below the timer unit, and a pressure regulating spring is abutting between the diaphragm and the side end of the valve cavity;

[0008] A sealing element is installed at the valve port formed by the pressure regulator housing structure, connected to the diaphragm, and one end of the timer unit can be inserted into the sealing element to control the sealing element to seal the valve port.

[0009] As described above, the timing voltage regulator with overcurrent cut-off function includes a pressure plate in the voltage regulating motion unit, and a sealed cavity is formed between the inner edge of the diaphragm and the pressure plate.

[0010] As described above, the timed voltage regulator with overcurrent cut-off function includes a sealing member comprising a connecting rod disposed below the diaphragm, and one end of the connecting rod penetrating the sealing cavity;

[0011] It also includes a lever, one end of which is hinged to the connecting rod, and the other end of which is connected to the valve pad at the valve port.

[0012] As described above, the timed voltage regulator with overcurrent cut-off function is provided with a connecting rod rivet ring for fixing at the connection between the connecting rod and the diaphragm.

[0013] The timer voltage regulator with overcurrent cutoff function described above: the regulator housing structure is provided with a top cover, and the top cover is equipped with a timer switch knob that can control the timer unit to turn off or on.

[0014] As described above, the timing voltage regulator with overcurrent cut-off function has a truncated cone-shaped structure for the voltage regulating spring.

[0015] The timed voltage regulator with overcurrent cut-off function as described above: a reset button unit is provided on the regulator housing structure, and an overcurrent cut-off unit is provided below the reset button unit.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By opening and closing the timer unit, in conjunction with the pressure regulating spring installed in the valve cavity, when the timer unit is open, the elastic force generated by the pressure regulating spring on the diaphragm can control the sealing element to conduct gas through the valve port, so that gas flows through the inside and outside of the valve port. When the timer unit is closed, the pulling force generated by the timer unit on the sealing element can control the sealing element to seal the valve port. Thus, the opening and closing of the valve port can be automatically controlled according to the opening and closing of the timer unit, effectively reducing the occurrence of gas safety accidents.

Detailed Implementation

[0022] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0023] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0024] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0025] Please see Figures 1-3 In this embodiment of the present invention, a timed voltage regulator with overcurrent cut-off function includes a voltage regulator cover structure formed by combining a lower housing 1 and an upper housing 2, wherein the lower housing 1 and the upper housing 2 are detachably connected, a valve cavity is formed inside the voltage regulator cover structure, and a timer unit 7 is installed inside the valve cavity; a voltage regulating motion unit 6 is provided inside the valve cavity, and the voltage regulating motion unit 6 includes;

[0026] A diaphragm 602 is disposed below the timer unit 7, and a pressure regulating spring 3 is abutted between the diaphragm 602 and the side end of the valve cavity;

[0027] A sealing element is installed at the valve port formed by the pressure regulator cover structure, connected to the diaphragm 602, and one end of the timer unit 7 can be inserted into the sealing element to control the sealing element to seal the valve port.

[0028] It should be noted that in this embodiment, the timer unit 7 is combined with the pressure regulating motion unit 6. When the timer unit 7 is in the open state, the diaphragm 602 in the pressure regulating motion unit 6 moves freely in the valve cavity. At this time, the pressure regulator works normally in the open state. When the timer unit 7 is in the closed state, the position of the diaphragm 602 is locked by the timer unit 7, so that the valve port is in the closed position and the pressure regulator is also in the closed state.

[0029] In detail, by controlling the timer unit 7 to be positioned above the diaphragm 602, when the timer unit 7 is turned on, the valve cavity of the diaphragm 602 can move freely under the action of the pressure regulating spring 3, thereby controlling the sealing element to conduct through the valve port, allowing gas to enter the valve cavity through the valve port. At this time, the diaphragm 602 remains balanced under the upward gas pressure and the action of the pressure regulating spring 3. When the timer unit 7 is turned off, the pulling force generated by the timer unit 7 on the sealing element is greater than the elastic force of the pressure regulating spring 3, causing the sealing element to block the valve port, cutting off the flow of gas, and effectively reducing the occurrence of gas safety accidents.

[0030] Preferably, a timer pad 8 is provided below the timer unit 7 inside the voltage regulator housing structure.

[0031] As a further embodiment of this invention, the pressure regulating motion unit 6 further includes a pressure plate 603, and a sealed cavity is formed between the inner edge of the diaphragm 602 and the pressure plate 603.

[0032] The sealing component includes a connecting rod 601 disposed below the diaphragm 602, and one end of the connecting rod 601 penetrates the sealing cavity;

[0033] It also includes a lever 605, one end of which is hinged to the connecting rod 601, and the other end is connected to the valve pad 606 at the valve port.

[0034] A connecting rod rivet ring 604 is provided at the connection between the connecting rod 601 and the diaphragm 602 for fixation.

[0035] During normal use, the timer unit 7 of the pressure regulator is in the open state. At this time, the diaphragm 602 will move downward under the action of the pressure regulating spring 3. When the diaphragm 602 moves downward, the connecting rod 601 moves downward simultaneously, causing the lever 605 to wobble and tilt downward at a certain angle. At this time, the valve port opens, and the gas can enter the valve chamber through the valve port. The gas entering the valve chamber generates upward gas pressure on the diaphragm 602. At this time, the diaphragm 602 remains in balance under the upward gas pressure and the action of the pressure regulating spring 3.

[0036] Conversely, when the regulator timing ends (as shown in the attached document) Figure 2As shown, the timer unit 7 of the pressure regulator is in the closed state. At this time, the timer unit 7 of the pressure regulator exerts an upward pulling force on the connecting rod 601. The pulling force is much greater than the compression force of the pressure regulating spring 3, so as to drive the connecting rod 601 to move upward, causing the lever 605 to swing, thereby causing the valve pad 606 to block the valve port, cut off the flow of gas, achieve the purpose of safety, and effectively reduce the occurrence of gas safety accidents.

[0037] The voltage regulator housing structure is provided with a top cover 9, and the top cover 9 is equipped with a timer switch knob 10 that can control the timer unit 7 to be turned off or on.

[0038] Preferably, the pressure regulating spring 3 is configured with a truncated cone shape, which enables the pressure regulating spring 3 to maintain a nearly constant spring stiffness during compression. This characteristic allows the pressure regulating spring 3 to provide stable support and adjustment capability when under force, avoiding instability caused by changes in the stiffness of the pressure regulating spring 3, and providing stable control over the sealing of the pressure regulator valve port.

[0039] Preferably, the voltage regulator housing structure is provided with a reset button unit 5, and an overcurrent cut-off unit 4 is provided below the reset button unit 5.
