[0027] See also Figures 1 to 5 A compact modular quick-connect household pressure regulator includes a valve body module consisting of a valve body 1 and a valve cover 2. A working chamber is provided in the valve body 1, and an air inlet 11 and an air outlet 12 are provided on the valve body. The working chamber is connected to the air inlet 11 and the air outlet 12.

[0028] In order to match a variety of national standard air inlet sizes or support personalized customized air inlet sizes, an air inlet module 3 that can match different air inlet sizes is provided at the air inlet part 11. Of course, a switch module 4 that cooperates with the air inlet module 3 is also provided on the valve body to realize the connection, locking or disconnection of the air inlet module 3 and the bottle valve.

[0029] The air inlet module 3 is detachable. When the pressure regulator needs to connect to different national standard air inlet sizes or customized air inlet sizes, it is only necessary to replace the air inlet module 3. There is no need to produce pressure regulators of various air inlet models separately, thereby reducing production costs and improving market competitiveness.

[0030] The working chamber of the valve body 1 includes, from bottom to top, the air inlet module assembly chamber 13, the switch module assembly chamber 13 and the air inlet module assembly chamber 13.

[0031] 14 and the pressure regulating chamber 15, the air outlet 12 is connected to the pressure regulating chamber 15, and the air inlet module 3 is arranged in the air inlet module assembly chamber 13

[0032] Inside, the switch module 4 is assembled in the switch module assembly cavity 14, and the pressure regulating assembly is arranged in the pressure regulating cavity 15. The valve cover 2 and the valve body 1 are assembled to form a pressure-bearing cavity 21, and the pressure-bearing assembly is arranged in the pressure-bearing cavity 21. The pressure regulation is achieved through the cooperation between the various components.

[0033] Among them, the air inlet module 3 is arranged in the air inlet module assembly cavity 13, including an air inlet seat 31, a locking ring 32 and an air inlet push rod assembly. The air inlet seat 31 and the locking ring 32 are coaxially connected. In order to improve the sealing of the assembly, a sealing gasket 301 is provided at the matching position between the air inlet 30 on the locking ring 32 and the air inlet module assembly cavity 13. The middle part of the air inlet seat 31 and the locking ring 32 are provided with a mounting portion for installing the air inlet push rod assembly. The air inlet push rod assembly is vertically installed in the middle of the air inlet seat 31 and the locking ring 32. The top of the air inlet push rod assembly extends into the switch module assembly cavity 14 and cooperates with the switch module 4. Furthermore, the air inlet push rod assembly includes an air inlet push rod 331 and a push rod spring 332 sleeved on the air inlet push rod 331.

[0034] The switch module 4 is assembled in the switch module assembly cavity 14, and the setting direction is perpendicular to the setting direction of the air inlet module 3. The switch module 4 includes a switch knob 41, a switch shaft 42 and a switch spring 43. A connecting cavity is provided in the switch knob 41, and the switch spring 43 is provided in the connecting cavity 410. One end of the switch shaft 42 is inserted in the connecting cavity and abuts against the switch spring 43 in the connecting cavity. The other end of the switch shaft 42 extends toward the middle of the switch module assembly cavity 14 to above the air intake push rod 331. An eccentric shaft is provided on the extended end of the switch shaft 42. When the switch knob 41 is rotated, the eccentric shaft on the switch shaft 42 will be driven to rotate, and then cooperate with the locking ring 32 and the air intake push rod 331.

[0035] An air inlet 5 communicating with the pressure regulating chamber 15 is provided at the top of the switch module assembly chamber 14 at one end away from the switch shaft 42, and an outlet 51 of the air inlet 5 protrudes into the pressure regulating chamber 15, and a pressure regulating assembly is provided above the air inlet outlet 51.

[0036] The pressure regulating assembly includes a lever 61 and a valve plug 62. The lever 61 is installed through a lever bracket 63 arranged in the pressure regulating chamber 15, and the lever is rotated on the lever bracket 63 through the axis. A connecting groove 611 is provided at the protruding end of the lever 61 for realizing linked pressure regulation with the pressure sensing assembly. A valve plug 62 is provided on the lower working surface of the lever 61 corresponding to the position of the air inlet outlet. In the non-working state, the valve plug 62 is plugged in the air inlet outlet 51. In the working state, under the action of gas pressure, the valve plug 62 is pushed up from the air inlet outlet 51, so that the switch module assembly chamber 14 is connected with the pressure regulating chamber 15.

[0037] The pressure-sensing component realizes linked pressure regulation through the connecting groove 611. The pressure-sensing component includes a diaphragm 71, a diaphragm plate 72 and a connecting rod 73 passing through the middle of the diaphragm 71 and the diaphragm plate 72. The lower end of the connecting rod 73 is clamped in the connecting groove 611. The diaphragm 71 is connected to the valve body 1 through the second mounting position 102 on the valve body, and the diaphragm plate 72 is arranged on the upper working surface of the diaphragm 71.

[0038] The valve cover 2 is assembled with the valve body 1 through the first mounting position 101 set on the valve body 1 to form a pressure-bearing chamber 21. The pressure-bearing component is set in the pressure-bearing chamber 21, including a pressure-bearing spring 81 and a pressure-regulating cover 82. The lower working end of the pressure-bearing spring 81 abuts against the upper working surface of the diaphragm 72, and the upper working end of the pressure-bearing spring 81 abuts against the pressure-regulating cover 82.

[0039] When the above technical solution is used, the principle is as follows: the air inlet module 3 can be divided into different types according to the size of the air inlet.

[0040] Specifications, common ones include 20mm, 22mm, 27mm, etc. Obviously, customized sizes are also included. When in use, select a suitable air inlet module and install it in the air inlet module assembly cavity 13 of the valve body 1. Then, by pressing down the entire structure, insert the air inlet module 3 into the bottle valve. Under the elastic force of the switch spring 43, the switch shaft pushes the lock ring to fix the bottle valve to prevent the connection from coming out. Rotate the switch knob counterclockwise to drive the switch shaft to rotate. The eccentric shaft at the extended end of the switch shaft drives the air inlet push rod to move downward, and the air inlet push rod pushes the top of the bottle valve. The needle opens the bottle valve, and the high-pressure gas in the bottle valve enters the valve body through the air inlet of the air inlet module, and enters the pressure regulating chamber through the air inlet duct. The diaphragm drives the diaphragm plate upward due to the action of the air pressure, and finally interacts with the pressure-bearing spring to achieve pressure balance, thereby reducing the high-pressure gas to low-pressure gas to achieve pressure reduction; rotate the switch knob clockwise, and the air inlet push rod retracts due to the force of the spring, pushing the switch knob, and the linkage lock ring retracts the lock ring from the lock groove of the bottle valve. The valve body will bounce upward due to the pressure of the sealing ring in the bottle valve and detach from the bottle valve, completing the disassembly.

[0041] The modular design of the air inlet module allows for flexible matching of air inlets and outlets of different sizes. The fixed valve body assembly can adapt to different air inlet interfaces, facilitating mass production. The universal component design can reduce the company's mold investment, reduce corporate costs, and improve its competitiveness.

The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
