Abstract
The utility model discloses an electromagnet. The electromagnet comprises an electromagnet body. The electromagnet body is connected with a power supply through a switch. A rectifier bridge and a temperature sensor are arranged between the electromagnet body and the switch. Preferably, the same shell is installed outside the electromagnet body, the rectifier bridge and the temperature sensor. The electromagnet has the advantages of being capable of being used by being directly connected with common mains power, highly universal, and effective in preventing the electromagnet from being burned.
Description
Technical field
The present invention relates to technical field of electric appliances, especially relate to a kind of electromagnet.
Background technology
Electromagnet is common electric.General, electromagnet comprises the electromagnet ontology that is comprised of coil and iron core, body is connected to power supply by switch (also can be attaching plug).Like this, behind the switch connection, coil electricity makes body can attract the materials such as iron.Its defective is: 1, the power supply that connects mostly is the 24V direct current, use thereby can't be connected to 220V electric main commonly used, thereby versatility is not strong.2, body in the course of the work, temperature can continue to raise.Long lasting service time when electromagnet, when then the temperature rising is higher, be easy to cause electromagnet to burn out.Therefore be necessary to be improved.
Summary of the invention
Deficiency for above-mentioned prior art exists the purpose of this invention is to provide a kind of electromagnet, and it has can directly access the civil power use, thereby versatility is stronger, simultaneously, and the characteristics that can effectively avoid electromagnet to burn out.
To achieve these goals, the technical solution adopted in the present invention is: electromagnet, comprise electromagnet ontology, and body is connected to power supply by switch, is provided with rectifier bridge and heat detector between described body and the switch.
Described body, rectifier bridge and heat detector outside are provided with common housing.
After adopting said structure, the present invention is compared with existing technology the advantage that has and is: 1, can be connected directly to common civil power and use, thereby versatility is stronger.Body of the present invention is connected with rectifier bridge, and rectifier bridge is transformed to the required direct currents such as 24V of body with the 220V electric main of civil power.That is, this electromagnet can be connected directly to civil power and use, and is comparatively convenient.2, can effectively avoid electromagnet to burn out.The body of electromagnet of the present invention is connected to power supply by heat detector.Like this, be adjusted to suitable parameter by the outage temperature with heat detector, in case then the temperature of body is increased to this outage temperature, then heat detector cuts off at once, make to form between body and the power supply and open circuit, and then the temperature of body is controlled under the suitable temperature, avoided burning out of electromagnet.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is the operation principle schematic diagram of embodiments of the invention.
Among the figure: 10, housing, L, body; D, rectifier bridge; R, heat detector; K, switch.
Embodiment
The following stated only is preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, as shown in Figure 1: electromagnet, comprise electromagnet ontology L, body L has iron core, and the iron core outside is wound with coil, and the coil of body L is connected to power supply by K switch.Simultaneously, be provided with rectifier bridge D and heat detector R between body L and the K switch.Like this, directly body L is connected to the 220V electric main after, rectifier bridge D is transformed to the 220V electric main direct current of the required 24V of body L or other voltage indexes, thereby comparatively convenient.Simultaneously, the temperature of body L is subject to the control of heat detector R, in case the excess Temperature of body L, then body L cuts off the power supply at once.Such as, the outage temperature of heat detector R can be adjusted to 120oC.Like this, in case the temperature of body L is increased to 120oC, then heat detector R opens circuit, and opens circuit thereby make to form between body L and the power supply.
Optimize, body L, rectifier bridge D and heat detector R outside are provided with common housing 10.That is, body L, rectifier bridge D and heat detector R are positioned at same housing 10.Like this, the integrated level of this electromagnet is higher.
Claims (2)
