Problems solved by technology

[0002] Existing timer comprises a power input electrode 1, the first power output electrode 2, the second power output electrode 3, the first gear and the second gear, the transmission gear set, the first fork and the timer housing, because two The power supply of the power output electrode has a variety of output modes, and each output mode represents the function of a product. For example, as long as one power output electrode is connected to the power input electrode alone, and the other power output electrode is disconnected, a power supply is realized. The output electrodes continuously supply power; if the two power output electrodes are connected to the power input electrodes at separate intervals, the two power output electrodes can be alternately powered, and there are other forms of power supply. There is also a micro switch A, B (see figure 1 ), if you choose only one power supply output electrode to supply power at separate intervals, you must start the corresponding micro switch to realize the power supply. This structure makes the circuit structure of the timer complex, and also reduces the stability and reliability of the timer when it is working. sex

Embodiment 1

[0022] Embodiment 1, in combination with Fig. 3, one side of the first gear 4 is a gear end 11, which can be connected with an external knob (not shown) on the timer housing, and the first gear can be adjusted by rotating the external knob. A gear 4 rotates, the other side of the first gear 4 has a central shaft 9, around the central shaft 9, two protruding blocks 15 are arranged on the side of the first gear 4, and the periphery of the first gear 4 protrudes radially One section of arc block 18. The center of the second gear 5 is a bearing sleeve 20, the outer ring circumference 12 periphery of the second gear 5 is provided with teeth, and the inner ring circumference 13 side of the second gear 5 is provided with two gaps 14, the second gear 5 Two protruding blocks 16 are provided on the circumference 13 of the inner ring, and the two notches 14 correspond to the two protruding blocks 16 at the same radial position one by one.

Embodiment 2

[0027] Example 2, combined with Figure 7 , rotate the external knob to make the first gear 4 rotate, so that one end of the first fork 7 and one end of the second fork 19 climb on the arc block 18 of the first gear 4, and the external knob must stop at In terms of another use function to be selected for household appliances, how does the second gear 5 rotate like this? Since the outer diameter of the arc-shaped block 18 is greater than the radius of the inner circle circumference 13 of the second gear 5, the corresponding first fork 7 The end will definitely not fall into the notch 14, because the end of the first fork 7 is subjected to a radially outward force along the first gear 4, so that the other end of the first fork 7 rotates the power input electrode 1 It is separated from the first power output electrode 2 and will not be closed yet. At this time, the power input electrode 1 is electrically connected to the transition electrode 24, and at the same time, the end of t...

Embodiment 3

[0028] Example 3, combined with Figure 8 , rotate the external knob to make the first gear 4 rotate. At this time, the external knob must stop on the fork-use function of the household appliance product, so that one end of the first fork 7 is located on the two protrusions on the surface of the first gear 4 Between the blocks 15, the end of the second fork 19 climbs up on the arc-shaped block 18 of the first gear 4, and the end of the second fork 19 is subjected to a radially outward force along the first gear 4, at this time The second power output electrode 3 is connected to the transition electrode 24, and the first fork 7 will fall into the gap 14 at intervals with the rotation of the second gear 5, and the power input electrode 1 and the first power output electrode 2 will be separated at intervals and connected, and when the power input electrode 1 and the first power output electrode 2 are disconnected, the power input electrode 1 will be connected to the transition el...

Abstract

The invention relates to a home electric appliance used timer. It comprises a power input electrode 1, two power output electrodes 2,3, two gears 4,5, a drive gear group 6, a fork 7 and a timer casing 8, wherein around the gear 4, it protrudes a section of arc block 18; around the gear 4, it also arranges a fork 19 which can rotates to the locating shaft 23 to swing; when end of the fork 19 it connected with the power output electrode 3; the other end of the fork 19 is around the gear 4; it arranges a transition electrode 24 between the power output electrode 3 and the power input electrode 1; the two ends of the transition electrode 24 are separately connected with the power output electrode 3 and the power input electrode 1.
