Description
technical fieldthe utility model relates to and evaporating in atmosphere by water and the conditioner making room air lower the temperature, and particularly relates to the outfit water-shortage protection device of air cooler.
background technologyabandoned the fabricated structure of reed pipe and switch in Chinese patent " being equipped with the air cooler of water-shortage protection device " (ZL2014207493876), adopt microswitch to realize lack of water protection, the structure of water-shortage protection device simplifies more.See Fig. 5, disclosed in described patent, the water-shortage protection device 2 of air cooler comprises float 22, transmission push rod 24 and microswitch 26, float 22 is arranged at directly over the inlet opening, bottom 11 of tank 1 inner chamber, the top attachment of described transmission push rod 24 one end and float 22, the other end is through the top cover 13 of tank 1, point to the actuating arm of the microswitch 26 be arranged on top cover, described microswitch 26 is arranged on microswitch fixed mount 25, described microswitch fixed mount 25 one end is fixed on the top cover 13 of tank 1, the other end is installed with microswitch 26, make the actuating arm of this microswitch 26 downward, towards the transmission push rod 24 stretched out on top cover 13, described microswitch 26 is electrically coupled to control circuit, the current pumped into by the inlet opening 11 of described tank 1 apply motive force upwards and buoyancy to the float being positioned at this water inlet, transmission push rod 24 is driven to move up and then extrude the actuating arm of microswitch 26, to movable contact and the stationary contact adhesive of microswitch 26, the signal of telecommunication that control circuit receives microswitch conducting is bestowed water level and is operated control normally, namely controls to comprise to control water pump to continue pump water and relay indicating light or icon display cistern water level normal, when inlet port 11 non-water flow of tank 1 pump into or water jet propulsion power and buoyancy not enough time, described float 22 and transmission push rod 24 move down due to gravity, thus make actuating arm resilience, the movable contact of microswitch 26 and stationary contact disconnect, control circuit receives the signal of telecommunication that microswitch disconnects and then the operation control bestowing water level abnormality, namely disconnect water pump to power, stop water pump pump water, relay indicating light or icon display water tank lacks water are reported to the police simultaneously.
In prior art water-shortage protection device; when float floats; very easily left and right skew, thus drive link cannot be touched effectively touch microswitch, in addition; microswitch be rotate according to the compressing tablet of drive link; compressing tablet promotes touch pole motion again, and finally drive the motion of switch internal shell fragment, shell fragment moves to certain position and breaks through its prefabricated elastic potential energy; the last closing of contact just making switch, switch poor sensitivity.
utility model contentthe utility model technical issues that need to address are to avoid above-mentioned the deficiencies in the prior art part and design a kind of air cooler having water-shortage protection device of production, solve prior art water-shortage protection device switch insufficient sensitivity, the problems such as poor reliability.
The technical scheme that the utility model proposes to solve the problems of the technologies described above is: a kind of water-shortage protection device of air cooler, described water-shortage protection device comprises float, transmission push rod and electronic switch, described float and transmission push rod are arranged in tank, and electronic switch is arranged on the top cover of tank; Described float assigns in the stopper slot of bottom of gullet, and the inlet opening of tank surrounds by the cell wall of described stopper slot; The external diameter of described float and the internal diameter of stopper slot suitable, float can only move up and down in stopper slot, can not move left and right; When tank is full of water, when float floats to extreme higher position, float can not depart from stopper slot completely.
More preferably, described electronic switch is contact switch, and the electroconductive elastic sheet of described contact switch is that the cantilever that one end is fixed is installed, and the movable end of described electroconductive elastic sheet is provided with the movable contact of this contact switch; The drive link being positioned at float upper end points to the movable end of the electroconductive elastic sheet of described contact switch; When described float floats, the electroconductive elastic sheet of transmission push rod upwards jack-up contact switch, makes the stationary contact of electroconductive elastic sheet contact with the stationary contact of the contact switch be fixed on above tank top cover, contact switch conducting; When the inlet port non-water flow of tank pump into or water jet propulsion power and buoyancy not enough time, described float and transmission push rod move down due to gravity, and electroconductive elastic sheet resilience, described contact switch disconnects.
More preferably, described float outer wall arranges outward extending boss, when tank is anhydrous, described boss is buckled in the notch place of stopper slot, and the bottom of float can not contact with water inlet actinal surface.
More preferably, bottom described stopper slot, nearly water inlet, is at least provided with two legs raised up, when tank is anhydrous or water shortage to make float float time, float is seated on leg, ensure water flow into swimmingly from water inlet.
Compared with the existing technology, the beneficial effects of the utility model are: structure is simple, and float is stressed more even, moves up and down more steady; Electronic switch is highly sensitive, and lack of water protective alarming performance is more reliable, effectively reduces the occurrence probability of wrong report.
