Description

Technical Field

[0001] The utility model relates to the technical field of timers, and more specifically, to a mechanical timer with remote control. Background Technique

[0002] At present, mechanical timers are widely used in various household electrical appliance products and are well-known to people. Timers can be divided into spring-driven and motor-driven types according to the power source. A spring-driven timer generally includes three parts: The first part is the power component, which consists of a spring and a one-way mechanism for winding the spring, so that when manually turned, the spring can only be tightened and will not rotate in the reverse direction to release the spring. Therefore, by tightening the spring, the power of the entire system is provided. The second part is the mechanism for releasing the energy of the spring, which is composed of a series of gears for speed reduction, increasing the number of rotations when the spring is relaxed. At the end of the gear train, there is an escapement wheel, an escapement pawl, and a hairspring to ensure that the gear train rotates at a constant speed driven by the spring. The above-mentioned hairspring has an adjustment device capable of adjusting its length to adjust the oscillation frequency of the escapement pawl, so as to ensure that the gear train rotates at a set speed, will not release the spring all at once, and is not affected by the tightness or looseness of the spring to cause changes in the rotation speed. The third part is the timing trigger mechanism. When the spring is tightened, the timing trigger mechanism is also triggered synchronously, that is, the contacts of the device to be timed are closed and the timing function is completed. Although the spring-driven timer is small in size and light in weight, the biggest problems it has are inaccurate timekeeping and short timing time inherently. And the motor-driven timer is relatively large in size because it includes a motor, and has disadvantages such as poor universality in use, inability to set periodic timing, and short timing time.

[0003] The utility model patent with the publication number CN215578358U discloses a mechanical track timer, which can set periodic timing, is small in size and light in weight, can completely cut off the power supply, and is more convenient to use. However, this timer is connected to the external load wiring through multiple wiring terminals, occupying the internal space of the timer and being inconvenient to use with many wirings. Content of the Utility Model

[0004] In view of this, in order to solve the above problems, the utility model proposes a mechanical timer with remote control, which does not need to be connected to the external load wiring through wiring terminals, and can be controlled by using a remote control circuit board 7, saving the internal space of the timer and being simple and convenient to operate.

[0005] A remotely controlled mechanical timer, comprising an upper housing 1 and a lower housing 2. A timing mechanism 3, a control mechanism 4 and a driving mechanism are provided between the upper housing 1 and the lower housing 2. The control mechanism 4 includes a microswitch 41 and a lever 42. The driving mechanism includes a motor 61. The motor 61 is arranged at the bottom of the timing mechanism 3 and is used to drive the timing mechanism 3 to rotate. The microswitch 41 and the lever 42 are arranged on one side of the motor 61. It is characterized in that: a remote control circuit board 7 is further provided in the lower housing 2. The remote control circuit board 7 is electrically connected to the microswitch 41. When the set time of the timer is reached, one end of the lever 42 abuts against the timing mechanism 3, and the other end abuts against the microswitch 41. The microswitch 41 is activated and transmits a signal to the remote control circuit board 7. The remote control circuit board 7 transmits a switch signal to an external signal receiver, notifying the external signal receiver that the time has arrived and the next action can be taken. When the timer has not reached the set time, one end of the lever 42 is away from the timing mechanism 3, and the other end is away from the microswitch 41. The microswitch 41 is turned off and no signal is transmitted to the remote control circuit board 7, and the external signal receiver does not receive the instruction.

[0006] Further, the surface of the timing mechanism 3 is a spherical body. The timing mechanism 3 includes a timing pin 31, a scale disk 32 and a pressure disk 33 from the outside to the inside. The timing pin 31 is composed of a plurality of inserts. The inserts have two states: an upward-pulled state and a downward-pressed state. When timing, the inserts corresponding to the corresponding time are in the downward-pressed state. When the inserts in the downward-pressed state rotate to the lever 42, the timing time is reached.

[0007] Further, a rotating shaft 62 is provided on the motor 61. A through hole 12 is provided on the upper housing 2. A gear is provided between the bottom of the pressure disk 33 and the scale disk 32. The rotating shaft 62 passes through the through hole 12 and is engaged with the gear. The pressure disk 33 is driven to rotate by the rotating shaft 62, so that the timing mechanism 3 rotates for timing.

[0008] Further, a bracket 8 is provided in the lower housing 2. The motor 61, the control mechanism 4 and the driving mechanism are all arranged on the bracket 8. A trigger block 411 is provided on one side of the microswitch 41 close to the lever 42.

[0009] Further, the lever 42 is in a shape of "yi". One end of the "yi"-shaped structure is a hook-shaped structure 421 extending upward, and the other end of the "yi"-shaped structure is a push block 422 extending downward. When the timing time is reached, the hook-shaped structure 421 contacts the lower part of the insert in the downward-pressed state, and the push block 422 abuts against the trigger block 411, and the microswitch 41 is activated and the timer is powered on. When the timer is timing, the hook-shaped structure 421 of the lever 42 is away from the timing mechanism 3, the push block 422 is away from the microswitch 41, and the motor 61 drives the timing mechanism 3 to rotate.

[0010] Further, a fixed shaft 423 extends downward from the middle of the lever 42. A fixed shaft sleeve 424 is provided on the bracket 8. The fixed shaft 423 is sleeved with the fixed shaft sleeve 424, so that the lever 42 swings with the fixed shaft sleeve 424 as a fulcrum.

[0011] Further, a key 71 is also provided on the remote control circuit board 7. A key protection sleeve 72 is provided at the top of the key 71. A key hole 11 is provided on the upper housing 1. The key 71 is inserted into the key hole 11. In the initial state, the key 71 is in the initial state. By setting the up and down states of the insert piece, the on and off of the micro switch 41 are automatically controlled, so as to transmit to the signal receiver whether to perform the next action; when the key 71 is pressed, the external signal receiver is immediately notified that it can perform the next action.

[0012] Further, a protective cover 9 is hinged at one end of the upper housing 1. The protective cover 9 is made of transparent material. The timing mechanism 3 is protected by the protective cover 9 while dust prevention is achieved, and the state of the timing mechanism 3 can be observed through the protective cover 9.

[0013] Further, a buckle 91 is provided at one end of the upper housing 1 away from the hinge. A snap ring 92 is provided at one end of the protective cover 9 away from the hinge. A first locking ring 93 is also provided on one side of the buckle 91. A second locking ring 94 is also provided on one side of the snap ring 92. When the protective cover 9 is closed, one end of the buckle 91 is snapped into the snap ring 92, so that the protective cover 9 is fixed to the upper housing 1. The protective cover 9 and the upper housing 1 are further fixed by inserting a pin through the first locking ring 93 and the second locking ring 94, preventing the protective cover 9 from being unable to protect the inside of the timer after the snap ring 92 or the buckle 91 is damaged.

The microswitch 41 is activated and transmits a signal to the remote control circuit board 7. The remote control circuit board 7 transmits a switch signal to an external signal receiver, notifying the external signal receiver that the time has arrived and the next action can be taken. When the timer has not reached the set time, one end of the lever 42 is away from the timing mechanism 3, and the other end is away from the microswitch 41. The microswitch 41 is closed, and no signal is transmitted to the remote control circuit board 7. The external signal receiver does not receive the instruction.
