The valve body 20 is a hollow cavity structure with two open ends, one end of the valve body 20 forms a water inlet 21, and the other end of the valve body 20 forms a water outlet 22.
The blocking block 23 is arranged in the hollow cavity of the valve body 20, the blocking block 23 separates the hollow cavity of the valve body 20 to obtain a water inlet cavity 24 and a water outlet cavity 25, the blocking block 23 is provided with a water flow through hole 26, and the water inlet cavity 24, the water flow through hole 26 and the water outlet cavity 25 are sequentially communicated to form a water flow channel.
The piston assembly 30 is mounted in the intake chamber 24; the opening and closing component 40 is arranged in the water outlet cavity 25; the coil assembly 50 is wound around the outside of the valve body 20.
The operating principle of the solenoid valve 10 for pressure regulation by mechanical force transmission is explained below:
energizing the coil assembly 50 such that the coil assembly 50 generates a magnetic field, the piston assembly 30 being influenced by the magnetic field to reciprocate back and forth within the intake chamber 24;
because the blocking block 23 is arranged in the hollow cavity of the valve body 20, the blocking block 23 is provided with the water flow through hole 26, according to the reciprocating motion state of the piston assembly 30, the water flow through hole 26 is blocked to be closed when the assembly 40 is opened and closed, and the water flow through hole 26 is separated to be opened when the assembly 40 is opened and closed, so that the water inlet cavity 24 can generate positive pressure and negative pressure;

Further, as shown in fig. 1, the solenoid valve 10 for pressure regulation by mechanical force transmission further includes a protective housing 60, and the protective housing 60 encloses the coil assembly 50. Thus, by providing the protective case 60, the coil assembly 50 can be effectively protected from the leakage phenomenon.
In particular, the solenoid valve 10 for pressure adjustment through mechanical force transmission further includes a pressure adjusting device 70 (shown in fig. 1), and the pressure adjusting device 70 is used for adaptively adjusting the air pressure of the hollow cavity of the valve body 20. For example, when the air pressure of the hollow cavity of the valve body 20 is greater than the external air pressure, the pressure regulating device 70 may discharge the air of the hollow cavity of the valve body 20, thereby achieving the balance of the internal air pressure and the external air pressure; for another example, when the air pressure in the hollow cavity of the valve body 20 is lower than the external air pressure, the pressure regulating device 70 may suck the external air into the hollow cavity of the valve body 20, so as to balance the internal air pressure and the external air pressure.
As shown in fig. 2 and 3, the pressure adjusting device 70 includes: the pressure regulating cylinder 100, the high-pressure exhaust plug 200, the low-pressure air inlet plug 300, the elastic support 400, the low-pressure air inlet cap 500 (shown in figure 4), the high-pressure exhaust cap 600 (shown in figure 4) and the middle push-pull connecting rod 700.
The pressure regulating cylinder 100 has a hollow cylinder structure with two open ends, the hollow cylinder of the pressure regulating cylinder 100 is communicated with the hollow cavity of the valve body 20, a high-pressure exhaust port 110 (shown in fig. 2) is formed at one end of the pressure regulating cylinder 100, and a low-pressure intake port 120 (shown in fig. 2) is formed at the other end of the pressure regulating cylinder 100.
The high pressure vent plug 200, the low pressure inlet plug 300 and the elastic support 400 are accommodated in the hollow cylinder of the pressure regulating cylinder 100, and the high pressure vent plug 200 and the low pressure inlet plug 300 are respectively disposed at both ends of the elastic support 400. In the present embodiment, the elastic supporting member 400 is a spring structure.
The high pressure vent plug 200 is pressed on the high pressure vent 110 by the elastic force of the elastic support 400; the low pressure intake plug 300 is pressed against the low pressure intake port 120 by the elastic force of the elastic support 400.
As shown in fig. 4, the high pressure vent plug 200 is provided with a low pressure air inlet hole 210, and the low pressure air inlet cap 500 covers the low pressure air inlet hole 210; the low-pressure air inlet plug 300 is provided with a high-pressure air outlet hole 310, and the high-pressure air outlet cover cap 600 covers the high-pressure air outlet hole 310; the low-pressure air inlet cap 500 and the high-pressure air outlet cap 600 are connected through an intermediate push-pull connecting rod 700.
The operation principle of the pressure adjusting device 70 will be described below:
in a state where the internal and external pressures are balanced, the high pressure exhaust plug 200 is pressed against the high pressure exhaust port 110 by the elastic force of the elastic support 400, and simultaneously, the low pressure intake plug 300 is pressed against the low pressure intake port 120 by the elastic force of the elastic support 400, at this time, the hollow cylinder of the pressure regulating cylinder 100 and the hollow cavity of the valve body 20 are in a non-through state;
when the air pressure of the hollow cavity of the valve body 20 is greater than the external air pressure, the air needs to be exhausted, so that the balance between the internal pressure and the external pressure is realized; specifically, the high-pressure airflow in the hollow cavity of the valve body 20 pushes the high-pressure vent plug 200, so that the high-pressure vent plug 200 can be separated from the high-pressure vent 110, and then the high-pressure airflow can reach the hollow cylinder of the pressure regulating cylinder 100 from the hollow cavity of the valve body 20; when the high-pressure vent plug 200 is separated from the high-pressure vent 110, the low-pressure air inlet cap 500 also moves along with the high-pressure vent plug 200, the low-pressure air inlet cap 500 further pushes the high-pressure air outlet cap 600 through the middle push-pull connecting rod 700, the high-pressure air outlet cap 600 is pushed by the middle push-pull connecting rod 700 to be separated from the high-pressure vent hole 310 on the low-pressure air inlet plug 300, and therefore high-pressure airflow originally entering the hollow cylinder of the pressure regulating cylinder 100 is further discharged to the external environment through the high-pressure vent hole 310; when the internal pressure and the external pressure are balanced again, the elastic support 400 prompts the high-pressure exhaust plug 200 to reset, the low-pressure air inlet cap 500 also resets along with the high-pressure exhaust plug 200, and the low-pressure air inlet cap 500 further pulls the high-pressure exhaust cap 600 through the middle push-pull connecting rod 700, so that the high-pressure exhaust cap 600 covers the high-pressure exhaust hole 310 of the low-pressure air inlet plug 300 again;
when the air pressure of the hollow cavity of the valve body 20 is lower than the external air pressure, air suction is required, so that the balance of the internal pressure and the external pressure is realized; specifically, because the hollow cavity of the valve body 20 is in a low-pressure environment state, the low-pressure air in the hollow cavity of the valve body 20 can suck the low-pressure air inlet cap 500, so that the low-pressure air inlet cap 500 is separated from the low-pressure air inlet 210 of the high-pressure air release plug 200, the low-pressure air inlet cap 500 further pulls the high-pressure air release cap 600 through the middle push-pull connecting rod 700, and the high-pressure air release cap 600 further drives the low-pressure air inlet plug 300 to be separated from the low-pressure air inlet 120, so that external high-pressure air flow can enter the hollow cavity of the valve body 20 through the hollow cylinder of the pressure regulating cylinder 100, thereby; when the internal pressure and the external pressure are balanced again, the elastic support 400 drives the low-pressure air inlet plug 300 to reset, the high-pressure exhaust cap 600 also resets, and the high-pressure exhaust cap 600 pulls the low-pressure air inlet cap 500 through the middle push-pull connecting rod 700, so that the low-pressure air inlet cap 500 covers the low-pressure air inlet hole 210 of the high-pressure exhaust plug 200 again.
As can be seen from the above description of the operating principle of the pressure regulating device 70, the middle push-pull connecting rod 700 is disposed between the low-pressure air inlet cap 500 and the high-pressure air outlet cap 600, and the middle push-pull connecting rod 700 realizes the push-pull actions on the low-pressure air inlet cap 500 and the high-pressure air outlet cap 600 in a mechanical force transmission manner, so as to further realize the balance adjustment of the internal and external pressures, and through the mechanical force transmission manner, the adhesion phenomenon between the low-pressure air inlet cap 500 and the high-pressure air outlet plug 200 and the adhesion phenomenon between the high-pressure air outlet cap 600 and the low-pressure air inlet plug 300 can be effectively.
As shown in fig. 3, in the present embodiment, the high-pressure vent plug 200 includes a vent plug body 201 and a vent plug guide pillar 202 disposed on the vent plug body 201; the low pressure inlet plug 300 includes an inlet plug body 301 and an inlet plug guide post 302 provided on the inlet plug body 301. It should be noted that, by providing the vent plug guide post 202 and the intake plug guide post 302, the vent plug guide post 202 and the intake plug guide post 302 are accommodated in the cavity of the spring, so that the vent plug body 201 and the intake plug body 301 can be guided, and the vent plug body 201 and the intake plug body 301 are prevented from tilting during movement.
Further, in order to increase the airtightness between the low pressure intake cap 500 and the low pressure intake holes 210 and also increase the airtightness between the high pressure exhaust cap 600 and the high pressure exhaust hole 310, the related structure needs to be optimally designed, and the following two embodiments are specifically disclosed:

In a similar way, the exhaust cover sealing guide groove is formed, so that the groove wall of the exhaust cover sealing guide groove forms an inclined surface, and the high-pressure exhaust cover cap 600 is of a circular truncated cone structure, so that the connection air tightness is improved.
