Description

Water tank with reed switch

The utility model relates to a water tank with a reed switch, which refers to a water tank which is arranged in household appliances for holding water.

Some appliances must have a water tank for collecting water, such as a dehumidifier. When the appliances are running, the outside water is sucked into the water tank for collection. When a certain amount of water is collected, it must be stopped and used. The tank is emptied before it can start running again.

In order to match the water level, the electrical appliance can be switched. Referring to FIG. 10 and FIG. 11, the water tank of the prior art appliance comprises a housing 50, a housing 60, a buoy 70 and a micro switch 80. The housing 60 Slidably disposed in the outer casing 50, the pontoon 70 is pivotally disposed at the top end of the casing 60, and a movable rod 701 is formed on one side of the pontoon 70. The actuating rod 701 extends through the casing 60, and the micro switch 80 is disposed outside the outer casing 50. A switch handle 801 is pivoted, and the switch handle 801 corresponds to the actuating lever 701. In a normal state, the pontoon 70 is horizontal and the actuating lever 701 is pressed against the switch handle 801. When the micro switch 80 is turned on and the appliance is operable, water continues to flow into the housing 60 for collection; when collected in the housing 60 When the amount of water is gradually increased, the water level rises to cause the float 70 to pivot until the actuating lever 701 is disengaged from the switch handle 801, and the switch handle 801 is bounced toward the inside of the case 60, and the actuating lever 701 abuts against the bottom of the switch handle 801. Between the end and the wall of the casing 60, the circuit is broken and the electrical appliance stops running. Therefore, the water does not flow into the casing 60. At this time, the user must pull the casing 60 to slide out of the casing 50 to pour out the water, so that the pontoon 70 can return to the horizontal state, and then push the casing 60 into the casing. 50, the actuating lever 701 is pressed against the switch handle 801 again, so that the micro switch 80 is turned on again and the appliance is re-operated.

However, since the pivoting of the pontoon 70 will cause the actuating lever 701 to abut against the bottom end of the switch handle 801 and the wall surface of the case 60, if the user inverts or shakes the mobile device, the pontoon 70 is pivoted. The pivoting pontoon 70 will cause the actuating lever 701 to be locked by the pivoting switch shank 801, and the actuating lever 701 may still abut even in the state of zero water level in the casing 60. At the bottom end of the switch handle 801, the micro switch 80 cannot be opened, and the user must pull out the box 60 and push it back into the box 60 to restart the appliance, which causes inconvenience in use.

In view of the above-mentioned shortcomings of the prior art, the present invention improves the structure of the water tank so that the pontoon can automatically return to the original position even if the water level does not reach the preset value, even though it is pivoted by mistake.

In order to achieve the above new object, the present invention designs a water tank with a reed switch, comprising: a hollow outer casing; a hollow casing slidably disposed in the outer casing; and a buoy pivoting the casing On one side of the pontoon, one side of the pontoon is formed with a movable rod, and the actuating rod is provided with a magnet; a reed switch is disposed on the outer wall surface of the outer casing and opposite to the actuating rod, the reed switch and the actuating rod Arranged at intervals, the reed switch includes a tube body and Two magnetic reed pieces, each magnetic reed piece is disposed in the tube body and has an outer end and an inner end, and the outer end of the magnetic reed piece penetrates outside the tube body and is electrically connected with an external circuit, and the inner ends of the two magnetic reed pieces Located in the tube and adjacent.

The advantage of the novel is that the magnetic force is the principle of the over-distance force, and the function of the switching path and the breaking circuit can be achieved through the magnetic force without contact between the actuating rod and the reed switch, and there is no need to set the engagement between the reed switch and the actuating rod. Structure, so the actuating rod only maintains the yaw position that causes the reed switch to open when the water level reaches the set height, and the rest is deflected by external force, as long as the external force is removed, the actuator rod can be actuated. The automatic return to the horizontal position causes the reed switch to form a path again. Therefore, the user can resume operation without the user performing additional actions in the non-full water state, thereby increasing the convenience of use.

The technical means adopted by the present invention for achieving a predetermined new purpose are further explained below in conjunction with the drawings and the preferred embodiment of the present invention.

Referring to FIGS. 1 and 2 , the present invention includes a housing 10 , a housing 20 , a pontoon 30 , and a reed switch 40 .

Referring to FIG. 2, FIG. 3 and FIG. 6, the outer casing 10 is hollow and has an opening 11 on one side, and a notch 12 is formed through the other side of the outer casing 10.

The casing 20 is slidably disposed in the opening 11 of the casing 10. The casing 20 is hollow and has an opening 21 on the top surface. One side of the casing 20 is formed with a notch 22, and the notch 22 of the casing 20 and the casing 10 are The gaps 12 are connected.

Referring to FIG. 3 and FIG. 4, the pontoon 30 is pivotally disposed on the side wall of the casing 20 and adjacent to the top surface of the casing 20. One side of the pontoon 30 is formed with a movable rod 31, and is actuated. The rod 31 is disposed in the notch 22 of the casing 20 and the notch 12 of the casing 10, and a magnet 32 is fixed to the end of the actuating rod 31.

Referring to FIG. 4 and FIG. 5, the reed switch 40 is fixed on the outer wall surface of the outer casing 10 and opposite to the end of the actuating lever 31, and the reed switch 40 is disposed at an interval from the actuating lever 31. The spring switch 40 includes a tube body 41 and two magnetic spring pieces 42. Each of the magnetic spring pieces 42 is disposed in the tube body 41 and has an outer end 421 and an inner end 422. The outer end 421 of the magnetic spring piece 42 extends through the tube. The body 41 is externally connected to an external circuit, and the inner ends 422 of the two magnetic reeds 42 are disposed in the tube body 41 and adjacent thereto.

Please refer to Figure 6 and Figure 7, when in general, the buoy 30 maintains the level such that the magnet 32 of the actuating lever 31 is aligned with the inner end 422 of the magnetic reed 42 and the magnetic field formed by the magnet 32 causes the inner end 422 of the two reeds 42 to deform against its own elastic force. When the electrodes are in contact with each other to form a conductive state, the electric appliance is in an operating state at this time.

Referring to FIGS. 8 and 9, when the amount of water collected in the casing 20 reaches a certain height to pivot the pontoon 30, when the magnet 32 of the actuating lever 31 is displaced from the relative position of the inner end 422 of the reed 42 In the state where the magnetic traction is lost, the inner ends 422 of the two magnetic reeds 42 are separated by their own elastic force, thereby forming an open circuit, so that the electric appliance is in a stopped state at this time.

Since the relative position between the actuating lever 31 and the reed switch 40 is changed by the relative position of the magnet 32 and the inner end 422 of the reed 42 to achieve the effect of the passage or the disconnection, there is no phase between the reed switch 40 and the actuating lever 31. In contact with the engagement, even if the pontoon 30 is inadvertently pivoted due to the user moving or colliding with the electric appliance, the actuating lever 31 is still deviated from the inner end 422 of the reed 42 when the water level does not reach the preset value. The relative position, the user does not need to pull out the box 20 again, as long as the electrical appliance returns to the normal position, the buoy 30 will automatically pivot back to the horizontal state, the actuating lever 31 can automatically return to the original position, and the reed switch 40 is again turned on. And the appliance continues to run.

Therefore, only when the water level reaches the preset height, the pontoon 30 can be maintained in the offset state after the pivoting, and the false touch in the remaining state can only temporarily pivot the pontoon 30, but the pontoon 30 is automatically activated when the external force disappears. Reverting to the horizontal position, the user does not need to perform additional actions, thereby increasing the convenience of use.

Moreover, since the reed switch 40 only needs to be fixed outside the outer casing 10, there is no need to additionally provide a pivoting structure or the like, so the whole of the present invention The structure is more streamlined.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Although the present invention has been disclosed above in the preferred embodiments, it is not intended to limit the present invention, and In general, those skilled in the art can make some modifications or modifications to equivalent embodiments by using the technical content disclosed above, without departing from the scope of the present invention. Any novel modifications, equivalent changes, and modifications made to the above embodiments are still within the scope of the present invention.
