Abstract

The utility model relates to a rotation speed and delay controller for electric fans, which is composed of a delayer and a piano key type range switch. A shift knob and a shift sleeve are sheathed on the rotary handle of the delayer, the shift knob and the shift sleeve are combined into integration, and are supported by a spring to mesh with the gear ring of the delay button. The shift sleeve is provided with a shift top convex. The piano key type range switch is provided with six keys, the stop key is a single key, and other keys are composed of an external key and an internal key. The steps of rotation speed is multiple, the gentle step is provided, and the automatic step shifting tome can be arbitrarily set. Except the control device, other parts of the utility model is the same as the existing electric fans of the similar kinds.

Description

Revolution speed and delay controller for electric fan

The utility model is a kind of rotating speed and overrun control of electric fan.

Along with living standard constantly improves, people are also more and more higher to the requirement of electric fan.Not only require electric fan energy fan-out gentle breeze in summer, but also requirement can be controlled the size of wind-force automatically.Time of electric fan work and close down at any time etc.Yet there are no this multiple functional product on the present market.Only reported also on the patent gazette that some had the patent application document of some aspect function.

The purpose of this utility model is a kind of multiple functional, the easy to use electric fan control gear of design.

Main rotating speed and time-delay control two-part by fan of the present utility model are formed.

The control of rotating speed is mainly finished by the piano keys type driving switch.The button of switch has six, and except that stop key was singly-bound, all the other constituted by external key and internal key.External key and internal key constitute independently five gear switch respectively.The internal key system has stretches out long gear shift contact, and when the gear shift contact was subjected to delaying time the compressing of gear shift parts, five internal keies were all out of supply.

Time-delay control is mainly finished by delayer.Be with a gear shift knob and shift sleeve on the swing handle of delayer.Gear shift knob and shift sleeve are an integral body, are withstood that by spring its gear ring with the time-delay button is meshed, and have gear shift top protruding on the shift sleeve, and in the time of above pushing up protruding being positioned at, jack-up lifts sheet, carries bit slice drive lever and depresses the gear shift contact.

The utility model is made up of piano key switch and delayer.Now respectively these two-part are described below.

The piano keys type driving switch is made up of 6 buttons, is the singly-bound except that stopping key, the cover key that external key was formed in all the other were, and 5 internal keies and 5 external keys of cover key are formed independently 5 gear switch separately.The internal key system has one to stretch out long gear shift contact, after the compressing that is subjected to delayer gear shift parts, can make 5 internal keies all out of supply and cut off the power supply.In addition, because the restoring force of delayer clockwork spring drive swing handle is little, can push internal key reliably for guaranteeing the automaitc shfit action, the lightly touching processing has all been done in the hook of internal key and hook position, and the elastic force of hook bar spring is also littler than the external key.

Be with a gear shift knob 8 and shift sleeve 5 on the swing handle 3 of delayer, gear shift knob 8 is an integral body with shift sleeve 5.There have a gear shift to push up on the shift sleeve to be protruding 6, and this top is protruding when forwarding the top to, but jack-up lifts sheet 10, and promptly begin automaitc shfit this moment, lifts sheet 10 and drive lever sheets 11 the gear shift contact of driving switch is depressed, thereby realize automaitc shfit.

Driving switch promptly can hand shift, again can automaitc shfit.With 1 grade of key of internal key is example, and the process of hand shift is described.When pressing this key, hook bar 13 moves to right, when off the hook hole 15 arrives the position of hooks 14, and hook bar 13 return of under the effect of hook bar spring 7, turning left.The bakelite sheet of this key bottom is depressed movable touching plate 2 and is made it to contact energising with stationary contact 12, motor is with 1 grade of rotation speed operation, if want shift, can press institute's shift selecting key, the moving to right of hook bar 13 broken off relations 1 grade of key and resetted, hook 14 hooks off the hook hole 15, makes 5 grades dynamic and static contact contact, and motor changes so that 5 grades of rotating speeds are moving.The principle and the above-mentioned principle of shutting down are basic identical.

During automaitc shfit, set the preceding top gear (as 1 grade) of gear shift, interior external key should be pressed simultaneously, and the bottom gear (as 5 grades) after the setting gear shift is only pressed external key.When pressing 5 grades of external keys, the shelves external key of pressing originally can break off relations and reset.What at this moment hooked has only 1 grade internal key and 5 grades external key.1,5 two grade of this moment all connect circuit, 5 grades the speed control coil short circuit but 1 grade of contact is named a person for a particular job, motor is still with 1 grade rotation speed operation.In case automaitc shfit action beginning is promptly pushed up protruding 6 and forwarded the top to, when jack-up lifted sheet 10, switch hook bar 13 displacements in gear shift contact 19 is being with made break off relations back return and cutting off the power supply of 1 grade of internal key.At this moment, 5 grades of coils are no longer by short circuit, and motor is with 5 grades of rotation speed operation, thus the realization automaitc shfit.After the automaitc shfit, delayer is when being in the time-delay state, and then motor still turns round, and up to the tripping of the contact of delayer, cuts off circuit and makes the motor stall.

If will delay time automaitc shfit, but the ceaselessly running always of the bottom gear after the gear shift can be opened tranquil closing, and when making delayer arrive delay cut-off, electric fan works on.Tranquil switch has 2 groups of contacts, and one group is connected in parallel on the delayer contact, another winding tutorial light of ceasing.Tranquil tutorial light is as reminds people, and this moment, electric fan was in this working method that ceaselessly turns round.

It is many to the utlity model has the rotating speed class.In the maximum delay scope, can set the moment of automaitc shfit arbitrarily.Also be provided with tranquil switch in addition, to satisfy the various working state needs of electric fan.

Claims

1, a kind of rotating speed of electric fan and overrun control, this installs by delayer, and the piano keys type driving switch is formed, and feature of the present utility model is, and the structure of delayer and piano keys type driving switch is respectively,
