Abstract
An oxygen-increasing machine with an air pressure switch comprises an oxygen-increasing machine, and is characterized in that the machine is further provided with an air pressure switch; the air pressure switch is composed of a mercury tube, mercury, a conductive cover, the contact of a power supply, and the contact of the oxygen-increasing machine; one end of the mercury tube is sealed while the other end thereof is open; the mercury is put in the mercury tube; the opening part of the mercury tube is covered with the conductive cover; both the contact of the power supply and the contact of the oxygen-increasing machine are correspondingly fixed on the pipe wall of the mercury tube and positioned above the conductive cover; and the contact of the oxygen-increasing machine is electrically connected with the power supply of the oxygen-increasing machine. The utility model has the advantages as follows: because the air pressure switch is additionally arranged, the utility model can automatically start up or close down the oxygen-increasing machine according to the variation of air pressure, oxygen shortage of fish pond can be prevented effectively, and the use is convenient.
Description
Technical field
The utility model relates to the aerator field of being with air pressure switch.
Background technology
The used aerator in existing fishing pond is mainly opened by artificial, and artificial unlatching often can not the fishing pond take place often because of anoxic in time for the oxygenation of fishing pond, and the incident that causes fish to die takes place.
The utility model content
The purpose of this utility model is exactly at the above-mentioned deficiency of aerator, and a kind of aerator with air pressure switch is provided.
The utility model comprises aerator 1, and it also has air pressure switch, and air pressure switch is made up of mercury tube 2, mercury 3, conductive cap 4, power contact 5, aerator contact 6; The sealing of mercury tube 2 one ends, other end opening, mercury 3 are placed in the mercury tube 2, conductive cap 4 is covered at the mercury tube opening part, power contact 5 and aerator contact 6 are fixed on the tube wall of mercury tube 2 respectively accordingly, are positioned at conductive cap 4 tops, and aerator contact 6 is electrically connected with the power supply of aerator.
The utility model has the advantages that: owing to added air pressure switch, it can open or close aerator automatically according to the variation of air pressure, can prevent fishing pond anoxic effectively, and is easy to use.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
As shown in drawings, the utility model comprises aerator 1, and it also has air pressure switch, and air pressure switch is made up of mercury tube 2, mercury 3, conductive cap 4, power contact 5, aerator contact 6; The sealing of mercury tube 2 one ends, other end opening, mercury 3 is placed in the mercury tube 2, conductive cap 4 seal covers are at the mercury tube opening part, and conductive cap 4 can slide up and down along the mercury tube wall, power contact 5 and aerator contact 6 are fixed on the tube wall of mercury tube 2 respectively accordingly, are positioned at conductive cap 4 tops, and aerator contact 6 is electrically connected with the power supply of aerator.
Operation principle: when atmospheric air pressure reduces, can cause fishing pond anoxic, the interior mercury of mercury tube this moment rises, and drives conductive cap and rises, and conductive cap is communicated with power contact 5 and aerator contact 6, starts aerator work.When atmospheric air pressure raise, the interior mercury of mercury tube this moment descended, and drives conductive cap and descends, and conductive cap and power contact 5 and aerator contact 6 are disconnected, and closed aerator.
