In the figure: 1. a filter screen top cover; 2. a left framework; 3. an evaporation core; 4. a pure water tank; 5. a right skeleton; 6. a liquid level probe cap; 7. a liquid level probe; 8. a probe silica gel plug; 9. and a UV germicidal lamp.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a liquid level probe detection device in humidifier, including pure water tank 4, lateral wall at pure water tank 4 is fixed mounting respectively has three liquid level probe 7 of group, every group is provided with two, three liquid level probe 7 of group are vertical distribution, three liquid level probe 7 of group are according to follow supreme low water level probe in proper order down, well water level probe and high water level probe, and the distance between every two sets of liquid level probe 7 is all different, low water level probe, the distance between the well water level probe is 83mm, and the distance between well water level probe and the high water level probe is 28mm, above-mentioned interval is put according to actual hand plate and reachs every day humidifying capacity in ordinary family room test, convert into the water consumption in the water tank, thereby it comes design size to reachd the high interval, neither extravagant, also save space, liquid level probe 7 is stainless steel, pure water tank 4 is the plastics material.

All fixedly cup jointed liquid level probe cap 6 in the district section that three liquid level probes 7 extend to pure water tank 4 outside, and the position that three liquid level probes 7 of group contacted with pure water tank 4 forms seal structure through probe silica gel stopper 8, guarantees not have the gap between water tank and the liquid level probe 7, and is water-tight, reaches sealed effect.

In addition, liquid level probe detection device still includes evaporation core 3 and the UV bactericidal lamp 9 of fixed mounting in the inside bottom of pure water tank 4 of fixed mounting in pure water tank 4 inside in this humidifier, has filter screen top cap 1 of size looks adaptation at the top fixed mounting of evaporation core 3, has fixedly cup jointed left skeleton 2 and right skeleton 5 respectively in the outside of evaporation core 3, and left skeleton 2 splices into the additional strengthening with evaporation core 3 external dimension looks adaptation jointly with right skeleton 5.

When the humidifier is used, the liquid level probe 7 is installed on the wall of the pure water tank 4 through the probe silica gel plug 8, after pure water is added into the humidifier, when the two low-water level probes detect that water exists, resistance is conducted, a signal can be sent to an electric control panel lamp (not shown in the figure) to display the low water level, and the humidifier can normally operate;

when the level value of the purified water added into the humidifier reaches the position of the two middle water level probes, the electric control panel lamp displays the middle water level; when the water reaches a high water level, the electric control board displays the high water level and reminds a client of the liquid level condition in the water tank at any time;

because the humidifier is a direct evaporation type humidifier (the humidifier is a common structure of the humidifier), the impeller (a structure is provided for the humidifier) is arranged at the top of the humidifier to rotate, so that evaporated water beads are emitted into the air, and the humidification effect is achieved;

when a user needs to sleep overnight and needs to start the humidifier, the water level needs to be added to a high water level, the humidification quantity of the humidifier is fixed, if the working time of the humidifier exceeds the set time, the high water level can still be detected by the detection of the liquid level probe, a signal can be fed back to an electric control program, and the machine is alarmed to stop working in time;

the liquid level probe detection device for the low water level, the medium water level and the high water level can feed back to a client immediately when water is added, so that the client is reminded in real time, and the pure water quantity of the water tank can be fed back to an electric control program in the use process of the humidifier so as to judge whether the humidifier works or give an alarm.

In the present embodiment, the model of the liquid level probe 7 adopts zp-495, and the structural features, the working principle and the specific circuit structure electrically connected with the outside are all adopted in the prior art, and are not described in detail herein.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
