The invention will now be further described with reference to the accompanying drawings.

As shown in FIG. 1 , the electromagnetic oscillation pump 10 of the embodiment of the present invention comprises a valve body 11 , a pressure relief valve, a water suction valve, a first spring 12 , a plunger 13 , a second spring 14 , a sleeve 15 , and a first iron ring . 16. The rubber ring 17, the second iron ring 18, the plastic sealing coil 19, the fixing frame 20, and the fixing cover 21. One end of the sleeve 15 is provided with a water inlet 151. One end of the valve body 11 is provided with a water outlet 111. The valve body 11 is provided with a center hole. The plunger 13 includes a plunger head 131 that is inserted into the center hole.

A pressing member 22 is disposed between the valve body 11 and the sleeve 15. The pressing member 22 is sleeved on the plunger head 131 of the plunger 13. A seal ring is disposed between the end surface of the pressing member 22 and the end surface of the valve body 11. The plunger head 131 passes through the central bore of the seal and is in an interference fit with the seal. The first spring 12 is pressed against the end face of the pressing member 22 facing the plunger 13. Optionally, no sealing ring is provided between the pressing member 22 and the end surface of the valve body 11.

The outer circumference of the end of the free end of the plunger head 131 is provided with a circumferential annular groove. A seal 23 is fixedly mounted in the annular groove. The annular groove can define a limit for the seal 23, and when the seal 23 moves in the center hole of the valve body 11 in synchronization with the plunger head 131, the annular groove can provide a thrust to the seal 23, ensuring that the seal 23 does not Movement in the axial direction of the plunger head 131 does not function to compress the sealed space 99. The plunger head 131 is inserted into the center hole of the valve body 11, and the seal member 23 is in contact with the hole wall of the center hole of the valve body 11.

An annular flange 112 is disposed on the inner wall of the central bore of the valve body 11, and the first spool 24 of the pressure relief valve is seated on the annular flange 112, and the annular flange 112 functions as a valve seat. The top of the first spool 24 is located in the hole formed by the annular flange 112 and does not protrude into the sealed space 99 beyond the hole, so that the first spool 24 never comes into contact with the second spool 25, thus avoiding the first A sticking phenomenon occurs between the spool 24 and the second spool 25. The second spool 25 of the suction valve is seated on the top of the plunger head 131, and the plunger head 131 functions as a valve seat. The second spool 25 of the suction valve is spaced from the annular flange 112 such that the first spool 24 of the pressure relief valve and the second spool 25 of the suction valve are opposite and spaced apart from each other.

As shown in FIGS. 1 and 2, the pressure relief valve, the valve body 11, the suction valve, the plunger head 131, and the seal 23 form a sealed space 99. This sealed space 99 belongs to a part of the central hole of the valve body 11. When the plunger 13 is subjected to the magnetic force generated by the plastic coil 19, the seal 23 can reciprocate in the center hole of the valve body 11 in synchronization with the plunger head 131 to change the volume of the sealed space 99. Preferably, the seal 23 is O Sealing ring.

In the long-term transportation, storage and the like, the first valve body 24 of the pressure relief valve and the annular flange 112, the second valve core 25 of the suction valve and the plunger head 131 may be adhered.

After the plastic coil 19 is energized, the plunger 13 will reciprocate in the sleeve 15. When the plunger head 131 moves toward the pressure relief valve, the plunger head 131 and the seal 23 compress the sealed space 99, the volume of the sealed space 99 is drastically reduced, and the substance (for example, air or water) in the sealed space 99 is compressed, thereby The pressure in the sealed space 99 rises sharply, and the pressure applied to the first spool 24 of the pressure relief valve becomes larger. When the first spool 24 of the pressure relief valve faces the surface of the sealed space 99, the pressure is greater than the atmospheric pressure acting on the first spool 24, and the first spool 24 receives a pressure difference greater than the first spool 24 and the annular When the adhesion between the flanges is reached, the first spool 24 and the annular flange 112 can be disengaged, so that the pressure relief valve is opened. After the first spool 24 of the pressure relief valve is opened, the substance of the sealed space 99 is discharged, and the pressure of the sealed space 99 becomes small.

After the pressure relief valve is opened, the plunger head 131 and the seal 23 start moving from the position closest to the first spool 24 of the pressure relief valve toward the first spool 24 remote from the pressure relief valve. During movement of the plunger head 131 and the seal 23 away from the pressure relief valve, the first spool 24 of the pressure relief valve is reset to seat on the annular flange to form a seal. The sealed space 99 starts to increase sharply, and substances (for example, air or air and water) in the sealed space 99 expand, and the pressure of the sealed space 99 sharply decreases. The pressure of the second spool 25 of the suction valve toward the first surface of the sealed space 99 is less than the atmospheric pressure acting on the second surface opposite the first surface, and the pressure difference of the second spool 25 of the suction valve When the adhesive force between the second valve body 25 and the plunger head 131 is greater than that, the second valve body 25 of the water suction valve is disengaged from the plunger head 131, and the water suction valve is opened.

When the plunger head 131 and the seal 23 reciprocate in the center hole of the valve body 11 and both the pressure relief valve and the suction valve are opened, the electromagnetic oscillation pump 10 enters a normal working state. The plunger 13 reciprocates to suck water from the water inlet 151, then opens the suction valve to push the water into the sealed space 99, and then opens the pressure relief valve to push the water out of the sealed space 99 and from the water outlet 111 of the valve body 11. Thus, the purpose of outputting a high-pressure fluid (for example, water) is achieved by the reciprocation of the plunger 13.

According to the electromagnetic oscillating pump 10 of the embodiment of the present invention, the sealing member 23 is disposed on the plunger head 131 and reciprocates in the central hole of the valve body 11 in synchronization with the plunger head 131, thereby providing a greater degree of The volume of the sealed space 99 is changed. When the moving distance of the plunger head 131 is short, the volume change amount of the sealed space 99 is also large, so that the first valve body 24 of the pressure relief valve and the second valve core 25 of the water suction valve are subjected to a greater pressure and are more easily separated. Bonding state, ensuring that the electromagnetic shock pump 10 after a long period of transportation, storage, etc. Still able to smoothly enter normal working conditions.

The electromagnetic oscillating pump 10 of the embodiment of the present invention changes the pressure of the first valve body 24 of the pressure relief valve or the second valve core 25 of the water suction valve by changing the volume of the substance passing through the sealing space 99, compared with the prior art. There is no direct contact between the first spool 24 of the pressure relief valve and the second spool 25 of the suction valve, so that the relative position of the first spool 24 of the pressure relief valve and the second spool 25 of the suction valve is low. Therefore, the electromagnetic oscillation pump 10 of the embodiment of the present invention does not cause failure due to the inaccurate relative position of the first valve core 24 of the pressure relief valve and the second valve core 25 of the water suction valve, and the electromagnetic oscillation pump 10 is better ensured. The effectiveness reduces the maintenance rate of the electromagnetic oscillating pump 10, which greatly saves costs. A gap is formed between the first valve body 24 of the pressure relief valve and the second valve core 25 of the water suction valve, and no direct contact occurs at all. The first valve core 24 of the pressure relief valve and the second valve core 25 of the water suction valve are not in contact with each other. Friction loss occurs and extends the service life.
