Technical Field

There are safety hazards such as the inability to close the valve due to damage to the mechanical manual switch and long-term water leakage and flooding. The above uncontrollable factors lead to waste of water resources.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] Reference Figure 1-5The present specific implementation adopts the following technical scheme: a light-touch magnetic control valve switch, comprising a switch cover 1, a metal magnetic cover 2, a magnetic material 3, a reset spring 4, a switch seat 5, a moving iron core spring 6, a moving iron core 7 and a sealing rubber particle 8, wherein the bottom end of the switch cover 1 is provided with a switch cover movable undercut 12, the switch cover 1 is inside a switch cover inner cavity 13, a metal magnetic cover fixing boss 11 is provided on the top of the switch cover inner cavity 13, the metal magnetic cover fixing boss 11 is fixed with the metal magnetic cover 2 to prevent the metal magnetic cover 2 from deviating from the center position when moving; the metal magnetic cover 2 is inside a metal magnetic cover inner cavity 21, the top of the metal magnetic cover inner cavity 21 is provided with a metal magnetic cover inner cavity 21, and the metal magnetic cover inner cavity 21 is provided with a metal magnetic cover fixing boss 11, and the metal magnetic cover fixing boss 11 is fixed with the metal magnetic cover 2 to prevent the metal magnetic cover 2 from deviating from the center position when moving; the metal magnetic cover 2 is inside a metal magnetic cover inner cavity 21, and the top of the metal magnetic cover inner cavity 21 is provided with a metal magnetic cover inner cavity 21. The switch cover 1 is fixed to the magnetic object 3 by magnetic attraction; a reset spring 4 is also placed in the inner cavity 21 of the metal magnetic conductive cover, the top of the reset spring 4 is against the bottom of the magnetic object 3, and the bottom of the reset spring 4 is pressed against the bottom of the switch seat inner cavity 57 of the switch seat 5; the outer wall of the switch seat 5 is provided with a guide groove 53, and the top of the guide groove 53 is provided with an undercut fixing position 54 higher than the guide groove, and the groove position of the guide groove 53 of the switch seat 5 cooperates with the raised position of the switch cover movable undercut 12 of the switch cover 1, which is used to fix and guide the switch cover 1 without deviating from the center when it moves up and down; the undercut top surface of the switch cover movable undercut 12 of the switch cover 1 is also connected to the switch seat 5 cooperates with the bottom surface of the inverted fixing position 54 (the top of the guide groove) of the switch cover 1 to fix the switch cover 1 to prevent the switch cover 1 and the switch seat 5 from loosening due to the force of the reset spring 4; the center position of the switch seat 5 is also provided with a movable iron core active cavity 51, and the outer top of the movable iron core active cavity 51 is an active cavity top 56, which is used to isolate the internal use pressure and the use medium of the movable iron core active cavity 51, and push the magnetic object 3 to fit with the active cavity top 56 when the switch cover 1 is pressed, so as to play a limiting role; the inner wall of the movable iron core active cavity 51 is provided with a plurality of active cavity guide columns 52 extending toward the top of the movable iron core active cavity 51, and the extension of the active cavity guide columns 52 The extended surface cooperates with the side surface of the moving iron core 7 to guide the moving iron core 7 to move up and down without deviating from the center, thereby reducing the resistance of the medium used; the moving iron core 7 is placed in the moving iron core active cavity 51 of the switch seat 5, and the moving iron core 7 supports the moving iron core spring 6. The top of the moving iron core spring 6 presses against the inner top of the moving iron core active cavity 51, thereby pushing the moving iron core 7 to move downward; a sealing rubber particle 8 is also fixed to the bottom of the moving iron core 7, and the bottom plane of the sealing rubber particle 8 is used to press against the top surface of the matching valve pressure relief hole to block or open the pressure relief hole; the bottom edge of the switch seat is also provided with a plurality of fixing holes 55 for installation with the water valve.

[0028] This specific implementation method uses the principle of magnetism and magnetic objects or magnetic objects attracting each other, and controls the valve switch by the magnetic object approaching or moving away from the moving iron core of the attracted object. Since the two are completely independent and in different spaces, the sealing effect of the switch will not be affected by the number of times they are used, which greatly reduces or eliminates the phenomenon of water leakage due to wear of the switch sealing ring;

[0029] This specific embodiment achieves the valve switch function by magnetic force in air-space attraction, thereby solving the problem that the traditional valve switch has different switch pressing forces due to different pressures inside the valve. The pressing force of the light-touch magnetic control valve switch of the invention depends on the elastic force of the internal reset spring and is not affected by the use pressure inside the valve, so that it can be pressed with a lighter force, which greatly improves the use feel;

[0030] This specific implementation method controls the opening and closing of the valve by moving the magnetic object close to or away from the moving iron core of the attracted object. Since the two are completely independent in different cavity spaces, they are not affected by the internal pressure of the valve and do not rub against the sealing ring, thereby greatly extending the life of the valve.

[0031] like Figure 6 As shown, the switch of the water circuit valve 9 is to push the valve diaphragm or piston 92 to move in the low pressure direction through the pressure difference between the pressure in the pressure balance chamber 93 and the inlet end to control the switch water of the valve (this example is a water circuit valve, and the medium used in this embodiment is water for illustration). For example, when the pressure inside the pressure balance chamber 93 is less than the pressure in the water inlet 100 direction of the water circuit valve 9, the water pressure in the inlet 100 direction will move the valve diaphragm or piston 92 in the direction of the valve cover 99. When the bottom of the valve diaphragm or piston 92 leaves the top of the valve water inlet 100, the water inlet 100 of the valve and the water outlet 97 form a passage, so that water can flow from the inlet end of the valve to the outlet end, thereby achieving the effect of opening the valve; the pressure relief hole 94 of the pressure balance chamber 93 uses an electric valve 91 or a mechanical manual switch to control the switch of the pressure relief hole 94 to achieve the effect of pressure relief or pressure replenishment.

[0032] like Figure 6As shown, the waterway valve 9 is controlled to open or close by the pressure balance or pressure difference between the pressure balance chamber 93 and the water inlet 100. The pressure of the pressure balance chamber 93 is discharged by opening the pressure relief hole 94 through the electric valve 91 or the light-touch magnetic switch. When the light-touch magnetic switch cover 1 is pressed, the switch cover 1 will move the metal magnetic cover 2 toward the switch seat 5. Since the magnetic object 3 is built into the top of the metal magnetic cover inner cavity 21 of the metal magnetic cover 2, the magnetic object 3 will move synchronously with the movement of the switch cover 1. When the switch cover 1 is pressed, the reset spring 6 will be compressed synchronously. When the magnetic object 3 is pushed by the switch cover 1, it will slowly approach the top 56 of the active cavity of the switch seat 5. Since the distance between the magnetic object 3 and the top 56 of the active cavity is shortened during the movement process, when the distance between the magnetic object 3 and the moving iron core 7 is shortened, the attraction (magnetic force) between the two is greatly increased. Therefore, when the magnetic object 3 is close to the top 56 of the active cavity, the moving iron core 7 is attracted by the magnetic force of the magnetic object 3 and moves toward the inner top of the moving iron core active cavity 51. Since the sealing rubber particles 8 used to block the pressure relief hole 94 are fixed on the moving iron core 7, when the moving iron core 7 is affected by the magnetic object 3, the moving iron core 7 is moved to the inner top of the moving iron core active cavity 51. When the sealing rubber particles 8 move due to the influence of magnetic force, they will synchronously drive the movement of the sealing rubber particles 8. When the sealing rubber particles 8 are driven by the moving iron core 7 to leave the sealing plane of the pressure relief hole 94, a passage will be formed between the moving iron core active chamber 21 and the pressure relief hole 94. The water and pressure of the pressure balance chamber 93 are discharged to the valve water outlet through the pressure-conducting water channel 96, the moving iron core active chamber 51, and the pressure relief hole 94 through the pressure relief water channel 95. At this time, the pressure of the pressure balance chamber 93 decreases because the pressure and water are discharged. Because the pressure in the direction of the water inlet 100 is greater than the pressure in the pressure balance chamber 93, the water and pressure at the water inlet 100 end will push the valve diaphragm or piston 92 to move toward the top of the pressure balance chamber 93. When the bottom of the valve diaphragm or piston 92 leaves the water sealing surface 101 of the water inlet 100, the water inlet 100 and the water outlet 97 of the water circuit valve 9 form a passage, so that water will flow to the water outlet of the water circuit valve through the water outlet 97 to achieve the effect of opening the water circuit valve 9.

[0033] like Figure 7As shown, when no external pressure is applied to the switch cover 1 of the touch-type magnetic switch, the magnetic object 3, the metal magnetic cover 2 and the switch cover 1 move toward the top of the reset spring 4 due to the force of the reset spring 4, and are suspended due to the mutual engagement and restriction of the switch cover movable undercut 12 of the switch cover 1 and the undercut fixing position 54 of the switch seat 5. As the distance between the magnetic object 3 and the moving iron core 7 becomes longer, the attraction (magnetic force) between the two is greatly weakened. Driven by the elastic force of the moving iron core spring 6, the moving iron core 7 and the sealing rubber particles 8 move toward the pressure relief hole 94 until the bottom plane of the sealing rubber particles 8 tightly presses the pressure relief hole 94. At this time, the pressure relief hole 94 is blocked by the sealing rubber particles 8 on the moving iron core 7, resulting in a closed circuit between the pressure balance chamber 93 and the pressure relief hole 94. The water and pressure in the direction of the water inlet 100 of the water circuit valve 9 will be replenished to the pressure balance chamber 93 through the diaphragm pilot hole 102. When the pressure balance chamber 93 is replenished with water or pressure, it will push the valve diaphragm or piston 92 to move toward the water inlet 100 of the water circuit valve 9 until the bottom surface of the valve diaphragm or piston 92 presses the water sealing surface 101 of the water circuit valve 9. At this time, the water inlet 100 of the water circuit valve 9 and the water outlet 97 form a closed circuit to achieve the effect of closing the water circuit valve 9.
