When the first valve cavity 118 and the second valve cavity 119 are in a connected state, the first valve cavity 118 and the second valve cavity 119 are connected, and at this time there is connection between the water inlet 111 and the water outlet 112, and the water path passing through the solenoid valve 100 is connected, and water flows through the solenoid valve 100. In this embodiment, the solenoid valve 100 realizes the regulation of the on-off of the water path.

Optionally, the throttling channel achieves throttling by adjusting the size of the connecting port between the first valve chamber 118 and the second valve chamber 119. Alternatively, a throttling channel can be added between the first valve chamber 118 and the second valve chamber 119. When the connecting port between the first valve chamber 118 and the second valve chamber 119 is blocked, the water entering from the first valve chamber 118 is throttled through the throttling channel, and then enters the second valve chamber 119, and then is discharged from the water outlet 112, so as to adjust the flow rate of the water flow. In this embodiment, the water inlet 111, the first valve chamber 118, the second valve chamber 119, and the connecting port therebetween or the throttling channel and the water outlet 112 all form a water flow channel in the valve body 110.

[0040] In some embodiments, the water sealing rib 117 can separate the inner cavity into a first valve cavity 118 and a second valve cavity 119 distributed on the left and right.

[0041] Alternatively, in some embodiments, please refer to Figure 3 and Figure 5The water sealing ribs 117 divide the inner cavity into a first valve cavity 118 and a second valve cavity 119 which are distributed in inner and outer rings, the second valve cavity 119 is located in the inner ring, and the first valve cavity 118 is located in the outer ring of the second valve cavity 119. Optionally, the water sealing ribs 117 form a cylindrical cavity along the circumference of the inner cavity, the cylindrical cavity is the second valve cavity 119, and the first valve cavity 118 is located in the circumference of the second valve cavity 119.

The valve core sleeve 131 is installed in the inner cavity of the valve body 110 and is located above the first valve cavity 118 and the second valve cavity 119. The valve core 132 is sleeved in the valve body 110 and moves toward the inner cavity of the valve body 110 or moves away from the inner cavity of the valve body 110.

[0043] When the valve core 132 blocks the second valve cavity 119 , the second valve cavity 119 and the first valve cavity 118 are not connected. When the valve core 132 moves upward, the second valve cavity 119 and the first valve cavity 118 can be connected.

The mounting seat is provided with a sleeve opening on a side away from the valve core 132 column, and the mounting seat is installed in the inner cavity of the valve body 110 (located above the first valve cavity 118 and the second valve cavity 119).

[0045] The valve core 132 includes a first end and a second end, wherein the first end extends along the sleeve opening of the valve core sleeve 131, and the second end is arranged opposite to the first end. The first end is used to switch the state of the conduction port, and an elastic member 133 is arranged between the second end and the valve core sleeve 131. The elastic member 133 may be a compression spring, which is used to apply a force to the valve core 132 to move toward the inner cavity of the valve body 110, so that the valve core 132 blocks the conduction port between the second valve cavity 119 and the first valve cavity 118; when the valve core 132 moves upward, the valve core 132 is separated from the second valve cavity 119, so that the conduction port between the second valve cavity 119 and the first valve cavity 118 can be opened, and the water inlet 111 and the water outlet 112 can be directly conducted through the first valve cavity 118 and the second valve cavity 119 without throttling. In this way, the first valve cavity 118 and the second valve cavity 119 are blocked or connected by the movement of the valve core 132, and the inner cavity of the valve body 110 of the solenoid valve 100 can be flushed based on high-pressure water pressure by direct connection to achieve self-cleaning.

Optionally, the probe 123 may extend into the water flow channel, or may not extend into the water flow channel, and the information of the water in the water flow channel is transmitted to the probe 123 through a conductor to detect the characteristics of the water (such as temperature). It should be noted that the conductor includes a heat conductor, such as the valve body 110, or other objects.

[0047] The probe 123 can detect the characteristics of water flowing through the water flow channel. Optionally, the sensor assembly 120 includes but is not limited to a turbidity sensor or a temperature sensor. If the sensor assembly 120 is a turbidity sensor, the probe 123 extends into the water flow channel to detect the turbidity of the water flowing through the water flow channel; if the sensor assembly 120 is a temperature sensor, the probe 123 may or may not extend into the water flow channel to detect the temperature of the water.

[0048] Optionally, in the embodiment where the probe 123 extends into the water channel, the probe 123 may be partially extended into the water channel or partially extended into the water channel. In a preferred embodiment, the probe 123 extending from the sensor assembly 120 is fully extended into the water channel.

[0049] Optionally, in this embodiment, the installation position 113 is formed by opening an avoidance position on the outer surface of the valve body 110, and the sensor assembly 120 is installed in the installation position 113 to form a whole with the valve body 110 without occupying additional installation space. Therefore, the sensor assembly 120 is integrated into the solenoid valve 100 without increasing the volume of the solenoid valve 100.

[0050] Optionally, when the sensor assembly 120 is used to detect water turbidity, a TDS sensor is used, and the TDS sensor includes two probes. When the sensor assembly 120 is used to detect water temperature, a temperature sensor is used, and the temperature sensor includes one probe.

[0051] Optionally, in some embodiments, the sensor assembly 120 can integrate multiple sensor elements to detect different water properties. These sensor assemblies 120 are provided with multiple probes, some of which are used to detect water turbidity, some of which are used to detect temperature, etc. Based on a set of sensor 120 assemblies, multiple information can be detected.

[0052] Optionally, in some other embodiments, a plurality of mounting positions 113 may be provided on the valve body 110 , and a plurality of the sensor assemblies 120 may be installed, and the specific number may be determined according to the size of the solenoid valve 100 and the setting space of the mounting positions 113 .

[0053] In this embodiment, by setting a mounting position 113 on the valve body 110, the sensor assembly 120 is installed on the mounting position 113, and the probe 123 of the sensor assembly 120 detects the water in the water flow channel based on the mounting position, and the sensor assembly 120 is integrated into the valve body 110, and does not need to be independently installed on the waterway plate of the drinking water equipment. The layout of functional components on the waterway plate can be reduced, and the volume of the waterway plate can be reduced to meet the miniaturization requirements of the drinking water equipment.

[0054] Alternatively, if Figure 4 and Figure 5 As shown, in this embodiment, the sensor is embedded in the valve body 110 and forms an integral structure with the valve body 110, so that the overall shape of the solenoid valve 100 remains unchanged. Figure 6 , the sensor assembly 120 includes a sensor body 121, and the sensor element is arranged in the sensor body 121. The sensor body 121 has a detection surface 122, and the probe 123 passes through the detection surface 122 and extends out of the sensor body 121. Among them, the mounting position 113 is provided with a mounting hole 114 connected to the water flow channel, the sensor body 121 is installed in the mounting position 113, and the probe 123 is located in the mounting hole 114. Based on the connection between the mounting hole 114 and the water flow channel, the probe 123 can collect information about the water in the water flow channel in the mounting hole 114. Optionally, the probe 123 extends into the water flow channel to collect water characteristics. In this way, the sensor assembly 120 is installed on the valve body 110, and the probe 123 of the sensor assembly 120 can contact the water flow channel to detect the water in the water flow channel.

[0055] Optionally, in order to prevent the water in the water flow channel from overflowing from the mounting hole 114. The sensor assembly 120 further includes a sealing boss 124 and a sealing member 129, wherein the sealing boss 124 is disposed on the detection surface 122, and the probe 123 passes through the sealing boss 124 and extends toward the water flow channel and into the water flow channel, or the probe 123 extends from the sensor body 121 into the sealing boss 124 and does not extend out of the sealing boss 124, and the water temperature of the water flow channel is detected by detecting the heat conducted by the sealing boss 124. When the sensor assembly 120 is installed at the mounting position 113, the sealing boss 124 is installed in the mounting hole 114 (the heat of the water in the water flow channel can be conducted to the sealing boss 124), and the sealing member 129 is sleeved on the sealing boss 124 and is in sealing contact with the hole wall of the mounting hole 114 to seal the mounting hole 114. Optionally, the diameter of the sealing member 129 is greater than or equal to the diameter of the mounting hole 114, so as to block the mounting hole 114 and prevent water from overflowing from the mounting hole 114. At the same time, the sensor body 121 can also be waterproofed and isolated.

[0056] Optionally, in some embodiments, the sensor assembly 120 can detect water temperature and water turbidity at the same time. The sensor assembly 120 includes a water temperature probe and a water turbidity probe. The water temperature probe is located in the sealing boss 124. The water turbidity probe passes through the sealing boss 124 and extends into the water flow channel. The sealing boss 124 conducts heat for the water temperature probe to detect, and the water turbidity probe extends into the water flow channel to detect the water turbidity. In this way, only the turbidity probe extends into the water flow channel, which takes up less space and can achieve simultaneous detection of temperature and turbidity.

[0057] Optionally, in order to limit and fix the seal 129 and prevent the seal 129 from falling off, the sensor assembly 120 also includes a limiting boss 125, and the limiting boss 125 is arranged on the outer peripheral wall of the sealing boss 124 and connected to the detection surface 122; or, the limiting boss 125 is arranged on the outer peripheral wall of the sealing boss 124 and connected to the detection surface 122.

[0058] The limiting boss 125 limits and positions the sealing member 129. On the one hand, the sealing member 129 can be prevented from falling off, and on the other hand, the sealing member 129 can be positioned so that the sealing member 129 can be sealed and isolated at a better position, thereby improving the sealing performance of the solenoid valve 100.

[0059] Optionally, the limiting boss 125 may be at least one protrusion disposed along the circumference of the sealing boss 124 , with the protrusions spaced apart. Alternatively, the limiting boss 125 may be a continuous protrusion disposed around the outer peripheral wall of the sealing boss 124 .

[0060] Optionally, the probe 123 of the sensor assembly 120 can be extended into any position of the water flow channel. Optionally, the water flow channel includes an inlet section (the flow channel between the water inlet and the first valve chamber) and a water outlet section (the flow channel between the second valve chamber and the water outlet). In a preferred embodiment, the probe 123 extends into the water outlet section. Since the second valve chamber 119 has the function of converging water flow, there will be no water loss zone in the water outlet section. Extending the probe 123 into the water outlet section can ensure the effect of detecting water. In addition, the space of the water inlet section is small, and the water inlet section is a high-pressure water chamber. If the probe 123 is set in the water inlet section, the water chamber space of the water inlet section is reduced, affecting the water intake of the solenoid valve. Extending the probe 123 into the water outlet section can avoid the above problems.

[0061] Optionally, the sensor assembly 120 further includes a wire 126, one end of which is connected to the probe 123, and the wire 126 is passed through the outside of the valve body 110. The wire 126 is used to transmit the signal detected by the probe 123 to the control device.

[0062] Optionally, in this embodiment, after the sensor assembly 120 is installed in the installation position 113, the water in the water channel can be detected by the probe 123, and the installation hole 114 can be sealed by the sealing member 129 on the sealing boss 124. In some embodiments, the sensor body 121 can be fixed by being embedded in the installation hole 114.

[0063] Alternatively, in some embodiments, the sensor body 121 and the valve body 110 can be fixed by snapping, such as an elastic snap is axially arranged in the mounting hole 114 of the valve body 110, the probe 123 enters the water flow channel through the mounting hole 114, the sealing boss 124 and the sealing member 129 are embedded in the mounting hole 114 to block the mounting hole 114, and the sensor body 121 is located outside the mounting hole 114 and is fixed to the mounting position 113 by the elastic snap. This method is convenient for installation and disassembly.

[0064] Alternatively, in some other embodiments, the sensor body 121 and the valve body 110 are fixed by screws 150. Since the solenoid valve 100 is used in drinking water equipment, the sealing requirement is relatively high. Compared with the snap-on fixing, the fixing method using screws 150 has better sealing and higher reliability. In this embodiment, the valve body 110 is provided with a first screw hole 116, and the first screw hole 116 extends to the installation position 113. The sensor body 121 is provided with a second screw hole 128, and the second screw hole 128 is coaxial with the first screw hole 116; the sensor body 121 is fixed to the installation position 113 of the valve body 110 by screws 150 passing through the first screw hole 116 and the second screw hole 128.
