Description
Technical Field
The utility model relates to a water tank with a magnetic reed switch, in particular to a water tank which is arranged in household appliances and is used for holding water.
Background
Some electrical appliances need to be equipped with a water tank for water storage to collect water, such as a dehumidifier, when the electrical appliances are operated, external water vapor is sucked into the water tank for collection, and when a certain amount of water is collected, the operation is stopped, and the operation can be restarted after a user empties the water tank.
Referring to fig. 10 and 11, in order to switch whether the electrical appliance operates according to the water level, the water tank of the prior art includes a housing 50, a tank 60, a float 70 and a micro switch 80, the tank 60 is slidably disposed in the housing 50, the float 70 is pivotally disposed at the top end of the tank 60, an actuating rod 701 is formed on one side of the float 70 in an extending manner, the actuating rod 701 penetrates through the tank 60, the micro switch 80 is disposed outside the housing 50 and pivotally disposed with a switch handle 801, and the switch handle 801 corresponds to the actuating rod 701. In a normal state, the float 70 is horizontal and the actuating rod 701 presses the switch handle 801, so that the micro switch 80 is turned on and the electric appliance can be operated, and water continuously flows into the box body 60 for collection; when the amount of water collected in the tank 60 increases gradually, the water level rises to pivot the float 70 until the actuating lever 701 disengages from the switch handle 801 to make the switch handle 801 bounce toward the inside of the tank 60, the actuating lever 701 abuts between the bottom end of the switch handle 801 and the wall surface of the tank 60, the circuit is broken and the electrical appliance stops operating, so that water does not flow into the tank 60, and at this time, the user must pull the tank 60 to slide out of the housing 50 to pour out the water therein, so that the float 70 can return to the horizontal state, and then push the tank 60 into the housing 50 to make the actuating lever 701 press the switch handle 801 again, so that the micro switch 80 is turned on again to make the electrical appliance operate again.
However, since the float 70 pivots to make the actuating rod 701 abut against the bottom end of the switch handle 801 and the wall surface of the box body 60, if the float 70 pivots due to careless inversion or shaking when the user moves the electric appliance, the pivoted float 70 makes the actuating rod 701 be caught by the pivoted switch handle 801 and cannot return to the original position, even in a zero water level state in the box body 60, the actuating rod 701 may abut against the bottom end of the switch handle 801 to disable the micro switch 80 to be opened, and the user needs to pull out the box body 60 and push the box body 60 into the box body 60 again to restart the electric appliance, which causes inconvenience in use.

Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.
Referring to fig. 1 and 2, the present invention includes a housing 10, a box 20, a float 30 and a reed switch 40.
Referring to fig. 2, 3 and 6, the housing 10 is hollow and has an opening 11 on one side, and a notch 12 is formed on the other side of the housing 10.
The box 20 is slidably disposed in the opening 11 of the housing 10, the box 20 is hollow and has an opening 21 on a top surface, a notch 22 is formed on one side of the box 20, and the notch 22 of the box 20 is communicated with the notch 12 of the housing 10.
Referring to fig. 3 and 4, the float 30 is pivotally disposed on the side wall of the box 20 and adjacent to the top surface of the box 20, an actuating rod 31 is formed on one side of the float 30, the actuating rod 31 is disposed through the notch 22 of the box 20 and the notch 12 of the housing 10, and a magnet 32 is fixed to the end of the actuating rod 31.
Referring to fig. 4 and 5, the reed switch 40 is fixedly disposed on the outer wall of the housing 10 and opposite to the end of the actuating rod 31, the reed switch 40 and the actuating rod 31 are disposed at an interval, the reed switch 40 includes a tube 41 and two reeds 42, each reed 42 is disposed in the tube 41 and has an outer end 421 and an inner end 422, the outer end 421 of the reed 42 penetrates through the tube 41 and is electrically connected to an external circuit, and the inner ends 422 of the reeds 42 are disposed in the tube 41 and adjacent to each other.
Referring to fig. 6 and 7, in a normal state, the float 30 is maintained horizontal, so that the magnet 32 of the actuating rod 31 is aligned with the inner ends 422 of the magnetic reeds 42, and the inner ends 422 of the two magnetic reeds 42 are deformed against their own elastic force by the magnetic field formed by the magnet 32, and are abutted to form a conducting state, and then the electric appliance is in a running state.
Referring to fig. 8 and 9, when the float 30 pivots when the amount of water collected in the tank 20 reaches a certain height, and the magnet 32 of the actuating rod 31 deviates from the relative position of the inner ends 422 of the magnetic reeds 42, the inner ends 422 of the two magnetic reeds 42 are separated by the elastic force of the magnet when the magnetic traction is lost, and thus an open circuit is formed, and therefore the electric appliance is in a stop state.
Since the relative position between the actuating rod 31 and the reed switch 40 is changed by the magnet 32 and the inner end 422 of the reed 42 to achieve the effect of opening or closing the circuit, there is no contact and engagement between the reed switch 40 and the actuating rod 31, even if the float 30 is inadvertently pivoted when the user moves or collides with the electric appliance, the actuating rod 31 is still deviated from the relative position of the inner end 422 of the reed 42 under the condition that the water level is not reached to the preset value, the user does not need to pull out the box 20, as long as the electric appliance returns to the normal position, the float 30 will automatically pivot back to the horizontal state, the actuating rod 31 can automatically return to the original position, and the reed switch 40 is turned on again and the electric appliance continues to operate.
Therefore, the float 30 can be maintained in the pivoted offset state only when the water level reaches the preset height, the float 30 can be pivoted temporarily only by the mistaken touch in the other states, but the float 30 automatically returns to the horizontal position after the external force disappears, so that the user does not need to perform additional actions, and the convenience in use is improved.
Furthermore, since the reed switch 40 only needs to be fixed outside the housing 10, and no additional structure such as pivot is needed, the structure of the present invention is simplified as a whole.
The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with the preferred embodiment, but not limited to the above description, any skilled person familiar with the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention, and any simple modification, equivalent change and modification made to the above embodiments by the technical solution of the present invention will still belong to the scope of the technical solution of the present invention.
