Description
Technical Field
The invention relates to the field of water purification equipment, in particular to a high-voltage switch used in a water purifier.
Background
The booster pump in the existing water purification product is controlled by a high-voltage switch. The pre-regulation stopping pressure (namely the pressure for switching on and off the high-voltage switch) of a remarkable high-voltage switch is 0.25 +/-0.02 MPa; the on-off differential pressure is 0.06 MPa. For the water purifying equipment with the water storage barrel, the phenomenon that the booster pump is frequently started when the water purifying equipment is used due to small on-off pressure difference can be caused. For a water purifying device with a control circuit, the unfavorable phenomenon can be relieved by controlling the delayed start of the booster pump through a program, but the solution can not fundamentally solve the contradiction that the start time of the booster pump is inconsistent with the water storage capacity of the water storage barrel due to the small on-off pressure difference. For the water purifying equipment without a control circuit, frequent starting of the booster pump cannot be avoided.
US4438305A (Johnson, 1984) discloses a pressure operated switchgear for providing a fire protection assembly for confining a fluid medium in the event of a fire. The disclosed pressure responsive device has a housing with a switching element, a pressure port and a channel through which pressure of a fluid medium is applied to a lower surface of a diaphragm. A flexible diaphragm is positioned to seal the upper end of the channel. The force applied by the fluid medium to the diaphragm is transferred to the piston, the piston can move up and down in a limited mode, and the lower surface of the piston is connected with the diaphragm. Under force, when the fluid pressure is sufficient to overcome the reaction force exerted by a spring coiled around the piston's shaft, the piston moves upward, and the shaft also extends upward from the spring. The upper end of the spring engages a flange extending from the adjustment nut through which the shaft of the piston slidably extends. The top end of the piston shaft is adjacent the plunger and depresses the plunger as the piston moves up to its extreme position. The plunger establishes a connection between the common terminal and the normally open terminal of the switching element as long as the fluid pressure is sufficiently high and the piston is maintained in the upper position and thus maintains the plunger in the depressed state. When the fluid pressure applied to the pressure port drops below a preselected level, the force of a spring coiled around the piston shaft drives the piston downward. In this position, the piston shaft releases the plunger, which establishes a connection between the common terminal and the normally closed terminal.
US4900883 (dome et al, 1990) discloses a fluid operated switch for providing selective actuation over a range of pressures or vacuums. The fluid operated switch discloses a chamber having an elastomeric diaphragm disposed therein. The lower surface of the diaphragm is in fluid communication through a channel, on the upper surface of the diaphragm is a radially held piston having an actuating rod that follows the flexing motion of the diaphragm. The actuating lever is aligned with the switch button of the electrical switch such that during the upper portion of the actuating lever stroke, the lever will depress the switch button to either make or break the electrical switch. The amount of force is proportional to the fluid pressure required to effect movement of the actuator rod to depress the switch button, which is determined in part by the degree of compression of the main spring captured between upper and lower spring guides connected to the actuator rod.
CN 203871212U (jjj. chekiang electrical appliances, 2014) discloses a high voltage switch for providing a waterproof system, preventing water and impurities from entering a housing, and ensuring stable operation.

The seal provided by the seal member ensures good sealing between the insert pin and the housing and prevents water and impurities from entering the housing well, thereby ensuring stable operation of the high-voltage switch.

The compression degree of the spring is adjusted through the adjuster, so that the spring generates elastic force acting on the piston, the piston moves towards the diaphragm, and the water inlet pressure is effectively improved. Conversely, the compression amount of the compression spring can be reduced through the pressure regulator, so that the water inlet pressure is relatively reduced, and the adjustment of the on-off pressure difference of the microswitch is realized.
A water purifier comprises a feed water inlet pipe and an RO reverse osmosis membrane filter connected to the feed water inlet pipe; a booster pump is arranged on the water supply inlet pipe, the purified water output pipe is connected to the RO reverse osmosis membrane filter, the water storage barrel is connected to the purified water output pipe through a water storage pipe, and a pressure regulating type high-pressure switch is arranged on the water storage pipe; the pressure regulating type high-voltage switch comprises a microswitch, a trigger assembly for triggering the microswitch, a valve body with a water flow channel arranged therein, a supporting piece fixed on the valve body and a piston arranged on the supporting piece and used for triggering the microswitch through the trigger assembly; the valve body is provided with a water passing channel communicated with the water flow channel, one end of the water passing channel is provided with a diaphragm, the diaphragm pushes the piston under the action of water pressure, a spring is arranged around the piston, the spring enables the piston to move towards the diaphragm, and the supporting piece is further provided with a regulator for regulating the compression degree of the spring. The structural style of the trigger assembly can effectively increase the pressure difference between the on pressure and the off pressure, so that when the water purifying device is used, the trigger assembly leaves the micro switch contact only when the water pressure in the water storage barrel is low enough, namely, only when the water stored in the water storage barrel is low enough, the booster pump starts to operate. The starting frequency of the booster pump is effectively reduced, and the problem that the starting time of the booster pump is inconsistent with the water storage amount of the water storage barrel is fundamentally solved.
The invention provides a voltage-regulating high-voltage switch, comprising:
the micro-switch is operated by a micro-switch,
a trigger assembly for triggering the microswitch,

a piston arranged in the support for triggering the microswitch by means of the trigger assembly;
a water passage in fluid communication with a water passage provided in the valve body,
a diaphragm provided at one end of the water passage, wherein the diaphragm pushes the piston under the action of water pressure,
a spring, wherein the spring moves the piston towards the diaphragm,
an adjuster, provided on the support, for adjusting the degree of compression of the spring; and

Since the slide is designed to be able to slide relative to the trigger part in the axial direction of the piston rod, the slide first slides in the trigger part under the action of the piston during the reduction of the water pressure; at this time, the trigger member does not move, that is, in this state, the micro switch is still in the off state. Only when the water pressure is low enough and reaches the connection pressure, the trigger piece leaves the contact of the micro switch under the driving action of the sliding block, so that the connection of the micro switch is realized. This arrangement allows the pressure difference between the cut-off pressure and the feed-through pressure to be large enough to reduce the frequency of starting the water pump as much as possible.
Preferably, the limiting assembly comprises a flat hole arranged on the sliding block and a limiting column arranged on the trigger piece; the limiting column is inserted into the flat hole and can slide along the length direction of the flat hole. The limiting assembly can also have other structural forms, for example, the limiting column is arranged on the sliding block, and the flat hole is arranged on the trigger piece.

Preferably, the water passage includes a water passing hole communicating with the water passage, and a first passage and a second passage connected to the water passing hole in succession. It is further preferred that the inner diameter of the first passage is smaller than the inner diameter of the second passage; therefore, water pressure can be transmitted to the diaphragm to drive the piston to act, meanwhile, the circulation of water in the main path is prevented from being interfered, and the problems of turbulence, noise and the like are prevented.

The chute is arranged on the trigger piece 21; the slider 22 is located within the slide channel and is slidable within the slide channel. The slider 22 is connected to the piston rod end of the piston 5 and is slidable in the axial direction of the piston rod relative to the trigger 21. The bottom of the slider 22 is provided with a connecting hole for inserting the piston rod; the piston rod is screwed to the connection hole to facilitate the separation of the trigger assembly 2 from the piston 5.
The trigger component 2 is also provided with a limiting component 23 for limiting the sliding displacement of the sliding block 22; the limiting assembly 23 comprises a flat hole 231 arranged on the sliding block 22 and a limiting column 232 arranged on the trigger 21. The stopper post 232 is inserted into the flat hole 231 and can slide along the length direction of the flat hole 231.
The middle portion of the support 4 is the support lumen 41. The piston head of the piston 5 is in sealing contact with the support inner cavity 41 and can slide in the support inner cavity 41; the piston rod of the piston 5 comes out of the support 4, protrudes from one end of the support 4 and is connected to the triggering assembly 2. Under the action of the piston 5, the slider 22 can be displaced and the movement of the slider 22 causes the trigger 21 to move, so that the trigger 21 triggers the microswitch 1. The microswitch 1 is provided with a retractable microswitch contact 12 and a signal output line 11 for outputting a control signal. Therefore, the extension/contraction of the micro switch contact 12 can be realized under the action of the trigger 12, so that the conduction and the disconnection of the internal circuit of the micro switch 1 are realized, and then different control signals are output to control components on the water path.
The valve body 3 is provided with a water passage 6 communicated with the water passage 31. The water passage 6 includes a water passing hole 61 communicating with the water passage 31, and a first passage 62 and a second passage 63 connected to the water passing hole 61 in succession. The first passage 62 and the second passage 63 together form a cavity of the valve body 3; the inner diameter of the first passage 62 is smaller than the inner diameter of the second passage 63, and the length of the first passage 62 is greater than the length of the second passage 63. One end of the water passage 6 is provided with a diaphragm 7, and the diaphragm 7 is elastically deformed under the action of water pressure, thereby pushing the piston 5. A spring 8 is arranged around the piston 5, which spring 8 causes the piston 5 to move towards the diaphragm 7.
An adjuster 9 is also provided on the support 4 for adjusting the degree of compression of the spring. The regulator 9 comprises an adjusting nut 91 and an adjusting seat 92, the adjusting nut 91 being arranged on top of the support 4, the adjusting seat 92 being connected to the adjusting nut 91 by means of a thread and enclosing the piston rod of the piston 5. One end of the spring 8 abuts against the piston head of the piston 5, and the other end abuts against the adjusting seat 92; when the adjustment nut 91 is turned, the adjustment seat 92 moves in the axial direction of the piston rod of the piston 5. In this embodiment, the adjustment seat 92 includes an adjustment lever and a spring seat connected to the adjustment lever; the adjustment rod may extend from the support 4 and its lever arm is provided with an external thread for cooperation with the adjustment nut 91. The adjusting seat 92 is provided with a recess in which the spring 8 engages and can adjust the high-voltage switch-on pressure to PONAnd adjusting the cutoff pressure to POFF. Contact pressure PONIs 0MPa and PONCan be adjusted by turning the adjusting nut 91. When the adjusting nut 91 is rotated clockwise, the adjusting seat 92 is driven to move axially downwards; when the spring 8 is compressed, PONThe value of (c) increases. In the opposite case, PONThe value of (c) is decreased.
In a normal state, the stopper post 232 is located at the lowermost portion of the flat hole 231. During operation, a water flow enters through the water inlet; most of the water flows out through the water outlet, but part of the water flows into the cavity of the valve body 3 through the water through hole 61 on the valve body 3. The diaphragm 7 is atThe valve body 3 moves under the action of water pressure in the cavity; when the water inlet pressure is more than PONAt this time, the diaphragm 7 drives the piston 5 to move upward. The pushing action of the piston 5 causes the trigger 21 and the slider 22 to move upwards simultaneously.
When the water inlet pressure reaches the cut-off pressure POFFAt this time, the contact of the slider 22 presses the micro switch contact 12 into the interior of the micro switch 1, the internal circuit of the micro switch 1 is broken, and the booster pump 300 connected to the micro switch 1 through the signal output line 11 stops operating.
When the water inlet pressure begins to be from POFFWhen lowered, the slider 22 moves downwards in the trigger 21 under the action of the spring. At this time, the trigger 21 is not moved by the frictional force of the microswitch contact 12. When the water inlet pressure is not less than PONAt this time, the microswitch 1 is in an off state.
Along with the reduction of the water inlet pressure, when the water inlet pressure is reduced to PONWhen the contact is opened, the trigger piece 21 is driven by the slide block 22 to be separated from the microswitch contact 12; the micro switch contact 12 is popped up, the internal circuit of the micro switch 1 is completed, and the booster pump 300 connected to the micro switch 1 through the signal output line 11 starts to operate.
Obviously, the high-voltage switch used in the present embodiment may be configured such that the on-pressure P isONAnd a breaking pressure POFFThere is a significant pressure differential therebetween. The high-voltage switch is utilized to reasonably control the starting time of the booster pump 300, thereby effectively reducing the frequent starting of the booster pump 300.
The present invention provides a water purifier, as shown in fig. 3, which includes a feed water inlet pipe 100 and an RO reverse osmosis membrane filter 200 connected to the feed water inlet pipe 100. The pressure reducing valve 101, the pre-filter 102, the water inlet solenoid valve and the booster pump 300 are sequentially disposed on the water inlet pipe 100. The RO reverse osmosis membrane filter 200 is connected to a purified water output tube 400 and a discharge output tube 500. The purified water outlet pipe 400 is provided with a downstream filter 401 and is connected to the water storage tub 601 via the water storage pipe 600. In addition, a check valve is provided at the water outlet of the purified water outlet pipe 400 to prevent the purified water from flowing back to the RO reverse osmosis membrane filter 200. The voltage regulating type high-voltage switch in the embodiment 1 is arranged on the water storage pipe 600; a combination flush valve 501 is provided on the discharge outlet pipe 500.
Also included is a control module connected to all of: a pressure reducing valve 101, a water inlet electromagnetic valve, a booster pump 300, a combined flushing valve 501 and a microswitch 1. One part of the purified water obtained after passing through the RO reverse osmosis membrane filter 200 flows into the water storage barrel 601 through the water outlet of the high-pressure switch, the other part of the purified water enters the inner cavity of the valve body 3 through the water through hole 61 on the valve body 3 and is triggered by the micro switch 1 through the piston 5 and the trigger piece 21 on the piston 5, so that the micro switch 1 is switched off or on, and a control signal is output to the control module through a signal output line 11 on the micro switch 1. The control module controls the pressure reducing valve 101, the water inlet solenoid valve, the booster pump 300, the combined flushing valve 501 and other components according to the received control signal so as to realize various functions of the water purifier.
The triggering assembly 2 in the high-voltage switch used in the present embodiment is of a special construction such that the switching-on pressure P isONAnd a breaking pressure POFFThere is a significant pressure differential therebetween; in addition, its initial switch-on pressure P can be regulatedON. Therefore, when the water purifying apparatus is used, the booster pump 300 will be operated only when the amount of water stored in the water storage tub 601 is sufficiently low below a certain value. This fundamentally solves the problem that the starting time of the booster pump 300 is not coordinated with the water storage amount of the water storage tub, and effectively reduces the problem that the booster pump 300 is frequently started.
In summary, the above-described embodiments are merely preferred embodiments of the invention. All equivalent changes and modifications made within the scope of the present patent application are intended to be included within the scope of the present patent application.
