Abstract

The utility model discloses an automatic timing power off device, including positive, power negative pole and heater, positive output cluster is connected with air switch, linked switch, time control switch and main road contact point, utmost point electric connection is correcied to main road contact point power input has button switch, button switch electric connection has contact point along separate routes, utmost point electric connection having heaters is correcied to the contact point power input along separate routes, negative pole electric connection in power negative pole is held to the heater power input. This automatic timing power off device reasonable in design uses convenient operation, through the time opening of main road closed circuit, realizes that closed circuit breaks off simultaneously along separate routes, and use in the especially adapted modern salt production technology heating process has very high practicality, has promoted this automatic timing power off device's service function nature greatly, guarantees its result of use and utilization benefit, is fit for extensively promoting.

Description

A kind of self-timing power-off function device

【Technical field】

This utility model is related to a kind of power-off, more particularly to a kind of self-timing power-off function device.

【Background technology】

Sal, also known as dining table salt, is and the most frequently used seasoning in culinary art to one of most important material of human survival Material.The main chemical Sodium Chloride (chemical formula NaCl) of salt in Sal content be 99% (belonging to mixture), some areas The Sal produced adds potassium chloride to reduce the content of Sodium Chloride to reduce mortality of hypertension.While world's most area Sal all by adding iodine preventing iodine deficiency, the Sal that with the addition of iodine is called iodine salt.

At present in technology of threonates, firing equipment does not have timing power-off function so that worked in production process all the time Personnel make an inspection tour and check, prevent over-heating from causing to produce the Quality Down of salt, waste time and energy.

【Utility model content】

Main purpose of the present utility model is to provide a kind of self-timing power-off function device, a kind of self-timing power-off function dress Put reasonable in design, using easy to operate, realize self-timing power-off function, it is to avoid superheated in salt production process, be adapted to extensively push away Extensively, can be with the problem in effectively solving background technology.

For achieving the above object, the technical scheme that this utility model is taken is：

A kind of self-timing power-off function device, including positive source, power cathode and heater, the positive source outfan Air switch, connecting valve, time control switch and main road contact point is serially connected with, the main road contact point power input is rectified Pole is electrically connected with button switch, and the button switch is electrically connected with bifurcated contact point, the bifurcated contact point source input Proper pole is electrically connected with having heaters, and the defeated place end negative pole of the heater power source is electrically connected at power cathode.

Further, the positive source input is also in series with protective tube, and protective tube is located at power input positive pole Connect on the line with time control switch and main road contact point.

Further, the main road contact point power output end negative pole is electrically connected at power cathode.

Compared with prior art, this utility model has the advantages that：A kind of self-timing power-off function device design Rationally, using easy to operate, disconnected by the timing of main road closed circuit, realize that branch closed circuit is simultaneously switched off, be especially suitable for Use in modern technology of threonates heating process, with very high practicality, greatly improves a kind of self-timing power-off function The use feature of device, it is ensured that its using effect and utilization benefit, is adapted to be widely popularized.

【Description of the drawings】

Fig. 1 is a kind of circuit system block diagram of self-timing power-off function device of this utility model.

【Specific embodiment】

Technological means, creation characteristic, reached purpose and effect for realizing this utility model is easy to understand, below With reference to specific embodiment, this utility model is expanded on further.

As shown in figure 1, a kind of self-timing power-off function device, including positive source, power cathode and heater, the power supply Cathode output end is serially connected with air switch, connecting valve, time control switch and main road contact point, the main road contact point electricity Source input anode is electrically connected with button switch, and the button switch is electrically connected with bifurcated contact point, the bifurcated contact Point source input anode is electrically connected with having heaters, and the heater power source input cathode is electrically connected at power cathode.

Wherein, the positive source input is also in series with protective tube, and protective tube be located at power input positive pole and when Between controlling switch and main road contact point connect on the line.

Wherein, the main road contact point power input negative pole is electrically connected at power cathode.

It should be noted that this utility model is a kind of self-timing power-off function device, and during work, under normal work, power supply Positive pole-protective tube-air switch-connecting valve-time control switch-main road contact point-power cathode, forms main closure electricity Road, the heater for controlling Salt Production are born by the positive pole-button switch-bifurcated contact point-heater-power supply on main road contact point Pole, forms branch closed circuit, when needing timing, presses the button switch and time control switch, and adjusts the time, fixed Shi Zidong disconnects the electric current of main closed circuit so that branch closed circuit also disconnects automatically, is determined in realizing salt production process automatically When power-off effect, it is ensured that a kind of utilization benefit of self-timing power-off function device.

Ultimate principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description Simply illustrate principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model is also Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed this utility model.This utility model Claimed scope is by appending claims and its equivalent thereof.
