Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description will be made in detail with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses a humidifier, including base 2 and water tank 1, set up basin 3 in the base 2, 1 overlap joint of water tank is on the basin 3, 1 bottom surface of water tank sets up the outlet pipe, the bottom and the one-way intercommunication of basin 3 of outlet pipe, 1 bottom surface of water tank sets up float 5, the embedded magnetic element 6 of float 5, magnetic element 6 is magnet, set up sensing element 7 in the basin 3, sensing element 7 is connected with 8 electricity of controller on the base 2, thereby controller 8 detects the break-make of the signal of telecommunication control humidification circuit of 7 outputs of sensing element, detect the water level of basin 3 through sensing element 7, effectively detect water tank 1 simultaneously and whether mention, when water tank 1 is lifted, cut off the humidification circuit, thereby promote the security greatly.

The sensing element 7 is arranged on the inner side wall of the water tank 3, the sensing element 7 is a Hall switching element, and the Hall switching element is positioned on the horizontal direction of the normal working water level in the vertical direction.

The bottom surface of the water tank 1 is provided with a limiting frame 4, the bottom end of the limiting frame 4 extends into the water tank 3, the bottom end of the limiting frame 4 is arranged below the water shortage liquid level of the water tank 3, the floater 5 is arranged in the limiting frame 4, and the floater 5 can change along with the water level change in the water tank 3 in the limiting frame 4.

Further, as shown in fig. 2, the limiting frame 4 is a cylindrical structure with an open top, an outwardly turned flange 41 is disposed at the opening of the limiting frame 4, a fixing hole 42 is disposed on the flange 41, the limiting frame 4 is fixed to the bottom surface of the water tank 1 by a bolt, and a communicating hole 43 is disposed on the cylindrical wall of the limiting frame 4, so that the interior of the limiting frame 4 is communicated with the water tank 3.

In order to enable the magnetic element 6 to always face the direction of the induction element 7 in the sinking and floating process of the floater 5, the cross section of the hollow cavity of the limiting frame 4 is non-circular, such as rectangular, square and hexagonal, the floater 5 is matched with the hollow cavity, and the floater 5 changes along with the change of the water level in the water tank 3.

The communication holes 43 may be long-strip-shaped through holes parallel to the axial lead of the limiting frame 4, or circular holes uniformly distributed on the wall of the limiting frame 4.

When the humidifier is operated, the float 5 drives the magnetic element 6 to change as the water level changes. When the water level is at the normal working water level, the floater 5 is relatively close to the Hall switch element, the magnetic field intensity is greater than H1, and the Hall switch element outputs V1; when the water level is in the water shortage state, the floater 5 is far away from the Hall switch element, and the magnetic field intensity is less than H2, the Hall switch element outputs V2. When the water tank 1 is lifted up, the hall switching element outputs V2 when the magnetic field strength of the float 5 is less than H2 as the water tank 1 moves away from the hall switching element. The controller 8 controls the working state of the humidifier by comparing the values of V1 and V2.

When the humidifier is operated, the magnetic element 6 is continuously lowered along with the water level, the magnetic element 6 is gradually close to the linear Hall sensor, so that the magnetic field intensity generated at the linear Hall sensor is gradually increased, the electric signal generated by the linear Hall sensor is gradually increased, when the water level in the water tank 3 reaches the water shortage level, the electric signal generated by the linear Hall sensor reaches the maximum value, and the water shortage level of the water tank 3 is controlled by setting the maximum value; the controller obtains the water level height in the water tank 3 by comparing the relation between the electric signal generated by the linear Hall sensor and a preset value; when the water tank 1 is lifted, the magnetic element 6 is gradually away from the linear hall sensor, so that the magnetic field intensity generated at the linear hall sensor is gradually reduced, namely, the electric signal generated by the linear hall sensor is gradually reduced, and whether the water tank 1 is lifted or not is judged by comparing the relation between the electric signal generated by the linear hall sensor and a preset minimum value.

As another embodiment, the sensing element 7 is disposed on the inner sidewall of the water tub 3, and the sensing element 7 is a linear hall sensor which is in a horizontal direction of a normal operation water level in a vertical direction.

When the humidifier operates, the magnetic element 6 is gradually far away from or close to the linear hall sensor along with the continuous decline of the water level, so that the magnetic field intensity generated at the linear hall sensor is subjected to one-way linear change, and the output voltage signal of the linear hall sensor is linearly increased or reduced. The controller 8 compares the output voltage value of the linear hall sensor with a preset value, thereby obtaining the water level height in the water tank 3.
