Abstract
The upper end and the middle part of the outer surface of the magnetic controlled pipe that is made of copper are respectively equipped with a boss, and the lower end of the outer surface is equipped with an external thread. The upper end of the internal chamber of the magnetic controlled pipe is equipped with an internal thread hole, the middle part is equipped with a round hole and the lower end is equipped with an internal thread hole where a retaining ring that is equipped with a central hole is installed internally. A hollow magnetic float is positioned in the round hole. The matrix of the hollow magnetic float is a round plastic sleeve that is provided with a central through-hole. The opening on the lower end of the matrix is stuck with a ring-shaped magnet by glue. A magnetic controller, which is equipped with a dry spring tube internally, is clamped on the magnetic controlled pipe and positioned between the two bosses. Two wires that are linked with the two pins of the dry spring tube are connected with an automatic electrical control system externally. The features of the utility model are that the utility model can not be blocked by foreign matters and the utility model is provided with a sensitive and reliable switch, simple structure, low processing cost, simple integration and easy maintenance. The utility model can be applied to various electrical heaters.
Description
Technical field
The electric controling part that a kind of electric heater is used, especially water-flow signal sensing element field.
Background technology
The water-flow signal sensing element that most of electric heaters adopt is the magnetic control water flow switch, and the signal that utilizes the magnetic control water flow switch to send is controlled the conducting and the disconnection of heating element circuit automatically.At present the magnetic float of all magnetic control water flow switches all is solid, and current pass through from magnetic float periphery and magnetron connect gap between the inwall.The defective that exists is that the gap is little, stops up easily and blocks, and often causes the fault of automatic Control Failure, therefore needs often to clean, and brings many inconvenience and worry to the user.
Summary of the invention
The purpose of this utility model provides a kind of magnetic control water flow switch with hollow magnetic float, accomplishes not block, and switch is flexible, and simple in structure, simple and convenient assembly.
Technical scheme is to make magnetic control with copper material to take over, and its inner chamber upper end is an internal thread hole for internal thread hole, middle part are the aperture greater than circular port, the lower end of internal thread hole, is installed with the back-up ring of band centre bore in this internal thread hole, and hollow magnetic float is positioned at circular port.The matrix of hollow magnetic float is the circular garment bag with central through hole, be adhesive with annular magnet on the seam of matrix lower end, in have the magnetic controller of tongue tube to be installed on magnetron to connect portion two external automatic electrical control systems of lead that link to each other respectively with two pins of jump ring pipe.
Using method and operation principle are as follows: the magnetic control water flow switch is vertically mounted in the inlet pipeline of electric heater, and its upper end is connected with heating cylinder water inlet, and the lower end is connected with the running water supply line.Connecing inner chamber at magnetron does not have under the state that current flow, because the deadweight of hollow magnetic float is greater than buoyancy, hollow magnetic float drops on the back-up ring, and its annular magnet is away from tongue tube.The magnetic field force that tongue tube receives a little less than, its not adhesive of contact is sent power-off signal to automatic electrical control system, instruction heating element circuit disconnects.Connecing inner chamber at magnetron has under the state of flow, and current flow into epicoele from the cavity of resorption of hollow magnetic float by hollow magnetic float central through hole.Because the damping action of hollow magnetic float central through hole, the pressure of cavity of resorption water are greater than the pressure of epicoele water, promptly cavity of resorption greater than to the pressure that epicoele produced, forms pressure differential to the pressure of hollow magnetic float generation.When water flow surpassed set point, upward pressure difference that hollow magnetic float is subjected to and buoyancy sum were conducted oneself with dignity greater than hollow magnetic float, both make a concerted effort promote hollow magnetic float and rise to magnetron inner chamber top.This moment, annular magnet was near tongue tube.The magnetic field force that tongue tube receives is stronger, and its contact is sent power on signal by adhesive to automatic electrical control system, instruction heating element power on circuitry, thus realized the purpose of current control on/off.
Compared with the prior art, characteristics of the present utility model are can not blocked by foreign material, and the switch sensitivity is reliable, simple in structure, processing cost is low, simple and convenient assembly, easy care, are suitable for various electric heaters and adopt.
