Abstract
The utility model relates to a liquid level sensor of an ultrasonic atomizer, which is provided with a sealed liquid level sensing component (6) which is extracted with a conducting wire (8) capable of electrically connecting with a control circuit board. The utility model is characterized in that the liquid level sensor of ultrasonic atomizer is also provided with a water shortage indicating lamp (5) connected with the liquid level sensing component into an integrated structure, and the water shortage indicating lamp is extracted with two conducting wires (7) capable of electrically connecting with the control circuit board. The utility model is provided with the water shortage indicating lamp connected with the liquid level sensing component into the integrated structure, the water shortage indicating lamp is turned off when an ultrasonic atomizer is used for spraying, and the water shortage indicating lamp is turned on when the ultrasonic atomizer stops spraying so that the utility model easily, definitely and visually indicates that a water shortage situation is happened for users and reminds the users to supplement water in time.
Description
Technical field
The utility model belongs to a kind of level sensor that is used for ultrasonic ultrasonic delay line memory.
Background technology
Referring to Fig. 1; on the fog-spray nozzle (1) of existing most ultrasonic ultrasonic delay line memories level sensor (2) is housed all; fog-spray nozzle is immersed back (referring to Fig. 2) in the water of tank (4); can respond to the water level height in the container; this class inductor is sealing; be connected with control circuit board one end in being sealed in the fog-spray nozzle housing by lead; water is connected with the circuit board other end; form an electric capacity like this between inductor (2) and the water; the variation of water level height can change the capacitance of inductor in the tank; when control circuit arrives to a certain degree by inductor changes in capacitance judgement water level is low, promptly send signal and stop spraying, realize the excessive low water level protection function.When existing atomizer stops to spray in the lack of water situation, all there is not clear and definite lack of water indication, a lot of user's constant errors think that atomizer breaks down, the atomizer spray head that has is provided with power light (3), but this class pilot lamp all is and the level sensor partial installation, no matter and spray, as long as power supply is connected, power light is all bright, can not indicate the generation of lack of water situation.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of ultrasonic ultrasonic delay line memory level sensor that is easy to clearly indicate to the user lack of water signal.
The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model is provided with the liquid level inductive means (6) of sealing, inductive means is drawn a lead (8) that can be electrically connected with control circuit board, it is characterized in that: also be provided with the lack of water pilot lamp (5) with fusing of liquid level inductive means structure, the lack of water pilot lamp is drawn all right one way or the other lead that is electrically connected with control circuit board (7).
Using method of the present utility model is: this inductor is installed on the fog-spray nozzle, the lead (8) that will be connected with inductive means and the lead (7) that is connected with the lack of water pilot lamp are electrically connected with control circuit board in the fog-spray nozzle housing respectively, and the lack of water pilot lamp is not worked when fog-spray nozzle is normally sprayed, reduce when stopping to spray and power connection is lighted at water level.
The utility model is provided with the lack of water pilot lamp with the inductive means integral structure, when it the time is not worked in spraying, when stopping spraying and lighting, is easy to clearly indicate the lack of water situation that taken place to the user intuitively, reminds the timely moisturizing of user.

Specific embodiments
Embodiment 1 (Fig. 3)
This routine level sensor is a column shape, and inductive means 6 is arranged on the column body, and lack of water pilot lamp 5 is arranged on the column top, and the lead 8 that is connected with inductive means is drawn from column body bottom with the lead 7 that is connected with the lack of water pilot lamp.
Referring to Fig. 6, this example can be vertically to being fixed on the fog-spray nozzle upper surface, the lead 7,8 of drawing from the lower end passes the fog-spray nozzle housing and is electrically connected with control circuit board in the housing, when water level reduces, control circuit board sends when stopping to spray signal, connect the lack of water pilot lamp power, send the lack of water signal to the user.
For avoiding confusion, install on the fog-spray nozzle of this level sensor common power light is not set.
