Description
Technical Field
The utility model relates to a humidifier.
Background
In the prior art, the humidifier comprises a base and a water tank which is covered above the base, and an atomization oscillation module, a water tank and a main controller are arranged in the base. The humidifier base is internally provided with a water level detection switch for detecting the water level of the water tank, the water level detection switch feeds a detected water level signal back to the humidifier main controller, the main controller judges whether the water in the water tank is enough or not according to the water level signal, and if the water level signal is enough, the humidifier keeps the working state of atomization and humidification. However, the current humidifier still has the following problems: (1) the water in the water tank is enough, but the water tank of the humidifier is lifted to be separated from the humidifier base, and the atomization oscillation module still works at the moment, so that water is sprayed to the upper part and the outside of the base, and external objects are wetted and damaged; (2) the water level detection switch is invalid, and the main control unit lacks the signal of basin water level and judges the source, and when leading to no water in the basin, main control unit still can let the humidifier be in the atomizing oscillation module always, and the condition of dry combustion method damage can appear in the machine.
SUMMERY OF THE UTILITY MODEL
The utility model provides a humidifier, it has overcome in the background art the not enough of prior art.
The utility model provides a technical scheme that its technical problem adopted is:
a humidifier comprises a base and a water tank covered above the base, wherein the base is provided with an outer shell, and a water tank, an atomization oscillation module and a main controller are arranged in a space surrounded by the outer shell; the position that corresponds the water tank bottom on this base is equipped with the electric capacity inductor that can produce the sensing signal to the aquatic products in the water tank, this electric capacity inductor and main control unit electric connection to can feed back sensing signal to main control unit, main control unit judges whether the water tank exists or whether there is water in the water tank according to this sensing signal.
In one embodiment: the capacitance sensor is arranged on the outer shell at the top of the base.
In one embodiment: the water level detection device is arranged in the base and used for acquiring a water level signal in the water tank, and the water level detection device is electrically connected with the main controller.
Compared with the background technology, the technical scheme has the following advantages:
the position that corresponds the water tank bottom on this base is equipped with the electric capacity inductor that can produce the sensing signal to the aquatic products in the water tank, this electric capacity inductor and main control unit electric connection, and can feed back sensing signal to main control unit, main control unit judges whether the water tank exists or whether there is water in the water tank according to this sensing signal, if judge that the water tank does not exist or does not have water, the steerable humidifier of main control unit is shut down or control atomization oscillation module stop work, prevent to drench the damage article or the condition that dry combustion method appears, play further guard action to the safe handling of humidifier, perfect the performance of humidifier, user experience has been improved.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is an overall schematic view of the humidifier according to this embodiment.
Fig. 2 is a sectional view of the humidifier according to the present embodiment.
Detailed Description
Referring to fig. 1 and 2, a humidifier comprises a base 1 and a water tank 2 covering the base 1, wherein the base 1 has an outer shell 11, and a water tank 12, an atomization oscillation module 13 and a main controller 14 (generally with a microprocessor MCU) are arranged in a space surrounded by the outer shell 11; the position that corresponds 2 bottoms of water tank on this base 1 is equipped with the electric capacity inductor 15 that can produce the sensing signal to the water in the water tank 2, this electric capacity inductor 15 and main control unit 14 electric connection to can feed back sensing signal to main control unit 14, main control unit 14 judges whether the water tank exists or whether there is water in the water tank according to this sensing signal. The capacitive sensor 15 functions like a touch button, and when the capacitive sensor 15 is close to water, the electric charge of the water acts on the sensing capacitance of the capacitive sensor 15 (i.e. changes the capacitance value of the capacitive sensor), so that the capacitive sensor 15 can sense the presence or absence of water in the vicinity.
Since the water tank 2 is covered on the base 1, the top of the base 1 is closest to the water tank 2, and the capacitance sensor 15 is arranged on the outer shell 11 at the top of the base 1, so that the water in the water tank 2 can be sensed better.
The humidifier also comprises a water level detector 16 arranged in the base 1 and used for acquiring a water level signal in the water tank, and the water level detector 16 is electrically connected with the main controller 14. On one hand, the humidifier detects whether the water in the water tank 12 reaches the water level through the water level detector 16 to determine whether the atomization working state is continuously maintained; on the other hand, the humidifier senses whether water exists in the water tank 2 through the capacitance sensor 15 (the result of sensing that the water tank 2 does not have water exists in two situations, namely, the water tank 2 is lifted to be separated from the base, and the water tank 2 does not have water exists), so that whether the atomization working state is continuously kept is determined, the defect that whether atomization is continuously carried out is judged only through the water level detector 16 is overcome, and double guarantee of preventing dry burning and the like is achieved.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
