Work as the rivers sensor detects rivers during through to in the inhalant canal to the controller sends feedback signal, the controller is received cut off during the feedback signal power supply circuit for even electrical apparatus and water are electrified also can not be through the pipeline of outside water source electrically conductive, avoid electrocuteeing wounded people, improve safe handling performance. When the water flow sensor detects that no water flows through the water inlet passage, the controller is communicated with the power circuit again. The power circuit can be switched off and connected by arranging a relay electrically connected with the controller.
It should be noted that, in this embodiment, schematic diagrams of elements such as a controller, a power supply circuit, and a relay of the electrical appliance are not provided without affecting understanding.
As shown in fig. 3, the joint body 11 is vertically through, and a partition 15 is disposed in the joint body, wherein the partition 15 divides the interior of the joint body into the water inlet passage 111 and the water outlet passage 112;
a first water inlet 113 is formed at one end of the joint body 11, and the first water inlet 113 is communicated with the water inlet passage 111 and is used for connecting an external water source;
the other end of the joint body 11 forms a first water outlet 114, and the first water outlet 114 is communicated with the water outlet passage 112 and is used for being connected with a water inlet of an electric appliance.
The filter element quick-connection mounting seat 12 is connected to the side surface of the joint body 11;
the water inlet passage 111 is provided with a second water outlet 115 formed by extending the wall of the water inlet passage 111 outwards to the filter element quick-connection mounting seat 12, and the second water outlet 115 is used for being connected with a raw water inlet 21 of the filter element 2;
the water outlet passage 112 is provided with a second water inlet 116 formed by extending the wall of the water outlet passage 112 outwards to the filter element quick-connection mounting seat 12, and the second water inlet 116 is used for being connected with the filtered water outlet 22 of the filter element 2.
When the filter element 2 is mounted on the filter element quick-connection mounting seat 12, an external water source flows into the water inlet passage 111 from the first water inlet 113, and then flows into the filter element 2 through the second water outlet 115 and the raw water inlet 21 for filtering; filtered water is obtained after being filtered by the filter element 2, and the filtered water flows into the water outlet passage 112 through the filtered water outlet 22 and the second water inlet 116, and finally flows into the interior of the electric appliance through the first water outlet 114. The utility model discloses a filter core connects 1 and sets up baffle 15 in its inside in order to form the water inlet passage 111 and the play water passage 112 that separate each other, the function is different, its compact structure, rationally distributed. Wherein the arrows in fig. 3 indicate the water flow direction.
For prolonging the service life of the filter element, as shown in fig. 3, a filter screen 117 which is integrally arc-shaped is arranged in the first water inlet 113, and the filter screen 117 protrudes towards the water inlet direction of the first water inlet. Outside water source earlier by behind the great impurity of filter screen 117 filtration, reentrant filter core 2 further filters, can reduce the entering the impurity of filter core to the extension the life of filter core. Will the filter screen is constructed into the bellied cambered surface shape of the water inlet direction towards first water inlet, helps increasing the area of contact of filter screen 117 with water, improves filtration efficiency. After the filter screen is used for a period of time, impurities are accumulated at the bottom of the cambered filter screen 117, and the side surface of the cambered filter screen 117 still has enough flow area for water to flow through, so that the filter screen does not need to be replaced frequently.
As shown in fig. 2 and 3, a concave thread groove 121 is formed on the inner side of the end portion of the filter element quick-connection mounting seat 12, and as shown in fig. 4, a projection 23 capable of being screwed into the concave thread groove 121 for matching is formed on the filter element 2. From this, the user only needs the one hand rotatory filter core, can with the filter core install to on the filter core connects the mount pad soon, or follow dismantle on the filter core connects the mount pad soon, convenient operation connects soon, need not to use other instruments. And because the filter element joint is internally provided with the one-way valve, the worry that water in the electric appliance flows out from the second water inlet in the dismounting process is avoided.
As shown in fig. 4, the filtered water outlet 22 of the filter element 1 is arranged at the central axis position of the filter element; a circle of diversion trenches 24 are arranged around the filtered water outlet, and the raw water inlet 21 of the filter element is communicated with the diversion trenches 24. The distance between the second water inlet 116 and the second water outlet 115 on the filter element joint 1 is matched with the distance between the filtered water outlet 22 and the diversion trench 24 on the filter element 2, so that when the filter element 2 is inserted on the filter element quick-connection mounting seat 12, the filtered water outlet 22 is just opposite to the second water inlet 116, and even if the filter element 2 rotates, the second water outlet 115 can still be communicated with the diversion trench 24 and further communicated with the raw water inlet 21.
In order to improve the connection strength between the filter element 2 and the filter element quick-connection mounting seat 12, a limiting protrusion 1211 is arranged at the bottom of the concave thread groove 121, and a limiting groove 231 matched with the limiting protrusion 1211 is arranged on the lower surface of the projection 23 of the filter element 2. When the filter element 2 and the filter element quick-connection mounting seat 12 are mounted in place, the limiting protrusion 1211 is inserted into the limiting groove 231 to limit the movement of the filter element 2 in the using process. Specifically, the edges of the limiting protrusion 1211 and the limiting groove 231 are in arc transition, so that the limiting protrusion 1211 can slightly deform under the action of external force to be clamped into or separated from the limiting groove 231, and the external force acts as torque force when the filter element 2 is screwed into or out of the filter element quick-connection mounting seat 12. In daily use, the filter cartridge 2 is difficult to be separated from the quick-connection mounting seat 12 due to the matching of the limiting protrusion 1211 and the limiting groove 231.
The utility model discloses a filter core connects has the anti-backflow function, with electrical safety performance high, be convenient for renew cartridge, be applicable to multiple electrical apparatus of wading.
The utility model also provides an electric appliance, which comprises the filter element joint; the electric appliance is provided with a water inlet, and the water inlet is connected with the filter element joint. If the filter element joint is used on an electric water heater, the first water outlet of the filter element is connected with the water inlet joint of the liner of the electric water heater. The electric water heater comprises the filter element joint, so that the electric water heater has all the beneficial effects of the filter element joint, and the description is omitted.
