Description

Multi-purpose timer

Multipurpose timer is a kind of device that mechanical timer switches on or off circuit that passes through that cooperates the consuming device use.

Present mechanical timer is not an independence, complete product, can not directly be used by independent and various consuming devices, be installed in the fan as a kind of accessory of fan factory only and use, regularly the limit is two hours, and can only the timing turning off circuit, can not regularly connect circuit.

The purpose of multipurpose timer provides a kind of mechanical timer: the direct adapted of the independent and various consuming devices of energy, regularly switch on or off circuit, and timing range is bigger, and is mobile, easy to use.

It mainly by base, lid, when the clockwork core is walked when mechanism, the control of cam shank mechanism, break-make selection mechanism and main contact etc. form.

Mechanism when the clockwork core is walked: when being the walking of common alarm clock machinery core partly.

The mechanism during control of cam shank: knob cam when a control that has a breach is arranged, elasticity tightly is enclosed within the hour hands axle head of clockwork core, and it can not drive hour hand axle and rotate, and hour hand axle but can drive it and rotate together.The shank axle is arranged on the frame of clockwork core, rotating shank is arranged on the shank axle, on the hook of shank kelly is housed.

Break-make selection mechanism: retainer spring sheet and break-make option board are arranged on base, and this plate can adopt the form of rotation or the form of slip, makes its location by the retainer spring sheet, continuous connection contact is arranged on the break-make option board and cut off contact.

Directly base-mounted main contact is being connected contact and is being cut off between the contact, regularly switches on or off circuit and be by pulling the break-make option board to change main contact and finish with the distance of connecting between contact or the cut-out contact.

On the capping or when control knob cam subscript be marked with regularly scale.

Draw a wire connecting power by main contact, draw a lead connection consuming device by connecting, cut off contact.Circuit loop is to return power supply through main contact to connecting contact to consuming device by power supply, and without shank, thereby if shank and base insulating material manufacturing, mechanism all should be uncharged when structure and clockwork core were walked during the control of cam shank.

The user is preferably in and loads onto attaching plug and consuming device socket on the base for convenience.By attaching plug phase line of power is connected main contact, zero line and ground wire are directly led to the consuming device socket, connect the phase line binding post of consuming device socket by the lead of connecting, the cut-out contact is drawn.This socket is as the power supply output that is timed device control.This multipurpose timer just becomes more complete separate component.For safety, the knob cam is all made with insulating material when base, lid, break-make option board, shank and control.

This multipurpose timer can directly cooperate regularly connection or timing turning off circuit by independent and various consuming devices, can arbitrarily move, and easy to use, regularly the limit is 10 hours.

Be described further with the embodiment that provides below in conjunction with accompanying drawing:

As shown in Figure 1, 2, 3, multipurpose timer mainly have base (1), lid (2), mechanism, break-make selection mechanism and main contact (3) etc. when mechanism, the control of cam shank when the clockwork core is walked.

As Fig. 3,6,9,10, during the control of cam shank mechanism comprise elasticity tightly be enclosed within hour hand axle (4) end have the control of breach the time knob cam (5), can and be contained in kelly (8) on the hook of shank around shank (7) that shank axle (6) rotates.As Fig. 3,5,7,8, break-make selection mechanism comprises retainer spring sheet (10), break-make option board (11), connects contact (12), cuts off contact (13) and break-make options button (14).

State before the multipurpose timer work is shown in Fig. 3,6, main contact this moment (3) contacts with connection contact (12), rubber-like master contact pushes away the unhooking end of shank (7) simultaneously downwards, shank rotates around shank axle (6), the breach of knob cam (5) (referring to Fig. 9,10) when making the hook of hook end upwards be absorbed in elasticity tightly to be enclosed within the control of hour hand axle (4) end.When hook was absorbed in breach, the kelly (8) (in the view of Fig. 6, kelly then is positioned at the following of hook) in the hook back also leaned on into the between cog at second hand wheel (9) gear is blocked, and makes clock out of service.

The process that multipurpose timer is regularly connected circuit is as follows: knob cam when (referring to Fig. 1,3) rotates control, transfer to give and fix time by being marked on timing scale (17) on the capping, cam backs down hook simultaneously, and the kelly behind the hook also leaves second hand wheel simultaneously, and clock is started working.When hook was backed down, unhooking end upwards pushed away main contact and has left the connection contact.At this moment, attaching plug (15) is inserted supply socket, make main contact energized, and the consuming device plug is inserted in the consuming device socket (16) of this multipurpose timer (referring to Fig. 4).Because main contact has left the connection contact, so circuit remains disconnection, it is not charged to connect contact and consuming device.

Fix time when clock moves to give, cam notch goes to the position over against bill again, because of elasticity master contact pushes away the shank unhooking end downwards shank is rotated, and hook upwards is absorbed in cam notch again, and the kelly behind the hook blocks second hand wheel again simultaneously, and clock promptly quits work.Contact (as Fig. 3) with the connection contact when elasticity master's contact promotes the shank unhooking end downwards, connected circuit, consuming device is started working.If the use electric cooker then begins the poach meal of stewing.

Multipurpose timer also can the timing turning off circuit: referring to Fig. 3,7,8, pull break-make options button (14) left, make break-make option board (11) change an angle, connect contact and just leave main contact, cut off contact (13) then near main contact, then locate by retainer spring sheet (10).Then, process as described above, the knob cam is fixed time to giving when rotating control, and cam backs down the hook of shank simultaneously, and the kelly behind the hook also leaves second hand wheel simultaneously, and clock is started working.When hook was backed down, unhooking end upwards pushed away main contact and contacts with cutting off contact, connects circuit, and consuming device is started working.

Fix time when clock moves to give, cam notch goes to the position over against bill again, the same reason, and hook upwards is absorbed in cam notch again, and the kelly behind the hook blocks second hand wheel simultaneously, and clock promptly quits work.Meanwhile, main contact resets because of its elasticity moves down, and leaves the cut-out contact, has cut off circuit, and consuming device also quits work.If the use electric fan then stops operating automatically.

Claims (2)
