Abstract
The utility model belongs to the technical field of automatic control switches and in particular relates to a float switch for a pump and automatically controlled by water level. The float switch is characterized in that a joint is connected to the upper wall of a shell; a micro switch is installed on the inner wall of the upper part of the shell and is turned on by a driving lever hinged on the middle inner wall of the shell; a limiting mechanism setting the movement range of a steel ball in the shell is formed on the inner wall on the lower part of the shell; the steel ball is arranged in the limiting mechanism; and the driving lever can be driven to rotate through upward movement of the steel ball and then turns on the micro switch. The float switch has the following advantages that the front and rear shells are butted to form a closed shell to prevent the outside liquid from entering the shell, thus ensuring the service lives of all the parts in the shell; the shell inclines under the buoyancy, the steel ball rolls in the cavity and the micro switch is touched and started by the driving lever, thus solving the problem that the water pump is in the working condition all the time due to lack of protective measures; and the float switch has the characteristics of simple structure, small size, low cost, convenience in installation and reliability in working.
Description
Technical field
The utility model belongs to the automatic control switch technical field, refers in particular to the pump that a kind of variation through water level controls keying automatically and uses switch.
Background technology
The function that immersible pump series products on the market does not does not open and close according to the SEA LEVEL VARIATION automatically controlled water pump mostly; Water pump is promptly started working after energized; Only after cutting off the electricity supply, can quit work, if do not have water in the container, water pump also can be in running order always; Have no protection, long-time rear motor and water pump are fragile.
At present; General switch mainly contains three kinds: first kind for electric pole type, and the electrical structure of electric pole type controller is simple, cost is low, easy for installation, but electromagnetic interference can have influence on the reliability of its work; The electrode that immerses simultaneously in the liquid damages easily, is not suitable for the immersible pump series products and uses; Second kind is the reed pipe formula, and reed pipe formula controller architecture is simple, reliable operation, but comparatively complicacy is installed, and the reed pipe element is difficult for buying, thereby is that installation and maintenance all bring difficulty; The third is a lever, and the lever controller architecture is simple, reliable operation, but volume is bigger, is not easy to make.
Summary of the invention
The purpose of the utility model provides a kind of pump of the automatic control of water level of immersible pump series products that is applicable to and uses switch.
The purpose of the utility model be achieved in that a kind of water level automatically the pump of control use switch; Be connected with joint on the upper wall of housing; On the inwall on housing top sensitive switch is installed, sensitive switch touches logically by being hinged on driving lever on the inwall of housing middle part, forms the position-limit mechanism of the scope of activities of regulation steel ball in housing on the inwall of lower housing portion; Be provided with steel ball in the position-limit mechanism, move on the steel ball and can drive driving lever and rotate and then touch logical sensitive switch.
Above-mentioned position-limit mechanism is the cavity that section is " 8 " font, and the internal diameter at cavity middle part is greater than the diameter of steel ball, and the inwall of cavity is provided with the groove that several losss of weight are used.
Above-mentioned housing comprises procapsid and back casing, and forward and backward housing butt joint forms airtight housing.
The utility model is compared the outstanding and beneficial technical effects of prior art:
1, the forward and backward housing butt joint of the utility model forms airtight housing, stops extraneous liquid to carry out in the housing, has guaranteed the useful life of each parts in the housing.
2, the other end of the joint of the utility model is connected on the immersible pump; Housing has a down dip in buoyancy; Steel ball rolls in cavity and touches sensitive switch through driving lever and starts; Solved water pump because of there not being the in running order always problem of safeguard measure, the inwall of cavity is provided with the groove that several losss of weight are used, have simple in structure, volume is little, cost is low, the characteristics of easy for installation, reliable operation.
Description of drawings
Fig. 1 is the internal structure sketch of the utility model when being in than low water level.
Fig. 2 is the internal structure sketch of the utility model when being in higher level.
Fig. 3 is that the utility model is installed on the immersible pump and the sketch map when being in higher level.
Among the figure: 1, housing; 11, dividing plate; 12, groove; 2, sensitive switch; 21, the contact of sensitive switch; 3, driving lever; 4, steel ball; 5, joint; 6, immersible pump body;
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3;
A kind of water level pump of control is automatically used switch; Be connected with on the upper wall of housing 1 on the inwall on joint 5, housing 1 top sensitive switch 2 is installed; Sensitive switch 2 touches logical by the driving lever that is hinged on the inwall of housing middle part; Form the position-limit mechanism of the scope of activities of regulation steel ball 4 in housing 4 on housing 1 lower inner wall, be provided with steel ball 4 in the position-limit mechanism, move on the steel ball 4 and can drive driving lever 3 and rotate and then touch logical sensitive switch.
Above-mentioned position-limit mechanism is the cavity that section is " 8 " font; The inwall of cavity is provided with the groove 12 that several losss of weight are used; Dividing plate 11 between adjacent two grooves 12 molds the reserve part behind the groove 12 for the inwall of cavity, and the internal diameter at cavity middle part is greater than the diameter of steel ball 4.
Above-mentioned housing 1 comprises procapsid and back casing, and forward and backward housing butt joint forms airtight housing, effectively stops outside liquid to get in the housing, has guaranteed the useful life of each parts in the housing.
When water level is low, the housing 1 natural bottom of switch, steel ball 4 is positioned at the bottom of housing 1, does not contact with driving lever 3 and sensitive switch 2, and this moment, sensitive switch 2 was in off-state, and the water pump circuit is not connected, and water pump is not worked.
When water level rises gradually, housing has a down dip in buoyancy, and the upper end of housing (is a sealed tube through joint; The two ends of sealed tube are connected with water pump with switch respectively) be connected with water pump; Steel ball 4 touches sensitive switch 2 contacts 21 through driving lever 3, thereby connects circuit, water pump entry into service.
The foregoing description is merely the preferred embodiment of the utility model, is not the protection range that limits the utility model according to this, so: the equivalence that all structures according to the utility model, shape, principle are done changes, and all should be covered by within the protection range of the utility model.
