Description
Technical field
The utility model relates to a kind of coffee machine timer.
Background technology
Coffee machine timer, comprise housing, one stretch into the main shaft in housing, the drive motors be located on housing, also timing-gear train is provided with in housing, the output of drive motors is connected with the input gear of timing-gear train, main shaft is provided with transition gear, the output gear of timing-gear train engages with transition gear, and in housing, be also provided with the reed coordinated with timing-gear train, carries out timing controlled by the break-make of reed.Its shortcoming also existed is: the useful life of reed is lower, and control mode is comparatively single.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing coffee machine timer, the coffee machine timer that the utility model provides a kind of longer service life, control mode various.
The technical scheme in the invention for solving the technical problem is: a kind of coffee machine timer, comprise housing, one stretch into the main shaft in described housing, the drive motors be located on described housing, also timing-gear train is provided with in described housing, the output of described drive motors is connected with the input gear of described timing-gear train, described main shaft is provided with transition gear, and the output gear of described timing-gear train engages with described transition gear;
Also be provided with a rotating cam in described housing, in the cam described in described main shaft inserts, described cam can be driven to rotate;
Also be provided with the first sensitive switch and the second sensitive switch in described housing, the input pin of described first sensitive switch connects power firestreak, and the output pin of described first sensitive switch connects load and described drive motors; The input pin of described second sensitive switch connects zero-power line, the drive motors described in output pin connection of described second sensitive switch;
Described cam can be touched mutually with the action reed of described first sensitive switch and the second sensitive switch thus can control the action reed of described first sensitive switch and the second sensitive switch;
When being in load normal open state, described cam makes the action reed of the second sensitive switch be in relaxation state, the action reed of the first sensitive switch is positioned at impaction state, thus the second sensitive switch disconnects and the first sensitive switch connection, now drive motors quits work, and load is in running order;
When being in definition status, described cam makes the action reed of the second sensitive switch be in impaction state, the action reed of the first sensitive switch is positioned at impaction state, thus the first sensitive switch, the second sensitive switch are all connected, now load is started working, and drive motors is also started working simultaneously; At the end of setting timing, described cam makes the action reed of the second sensitive switch be in impaction state, the action reed of the first sensitive switch is positioned at relaxation state, thus the second sensitive switch is connected and the first sensitive switch disconnection, now drive motors and load all quits work.
The beneficial effects of the utility model are: adopt sensitive switch to realize timing controlled with coordinating of cam, and can realize multiple control modes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation after the utility model removes transition gear.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of coffee machine timer, comprise housing 1, and stretch into the main shaft 2 in described housing, the drive motors 3 be located on described housing 1, timing-gear train 4 is also provided with in described housing 1, the output of described drive motors 3 is connected with the input gear of described timing-gear train 4, described main shaft 2 is provided with transition gear 5, and the output gear of described timing-gear train 4 engages with described transition gear 5;
Also be provided with a rotating cam 6 in described housing 1, described main shaft 2 to insert in described cam 6 thus described cam 6 can be driven to rotate;
Also be provided with the first sensitive switch 7 and the second sensitive switch 8 in described housing 1, the input pin of described first sensitive switch 7 connects power firestreak, and the output pin of described first sensitive switch 7 connects load and described drive motors; The input pin of described second sensitive switch 8 connects zero-power line, the drive motors described in output pin connection of described second sensitive switch 8;
Described cam 6 can be touched with action reed 9 phase of described first sensitive switch 7 and the second sensitive switch 8 thus can control the action reed 9 of described first sensitive switch 7 and the second sensitive switch 8;
When being in load normal open state, described cam 6 is rotated by main shaft 2, described cam 6 makes the action reed of the second sensitive switch 8 be in relaxation state, the action reed of the first sensitive switch 7 is positioned at impaction state, thus the second sensitive switch 8 disconnects and the first sensitive switch 6 is connected, now drive motors 3 quits work, and load is in running order;
When being in definition status, described cam 6 is rotated by main shaft 2, described cam make 6 the action reeds of the second sensitive switch 8 are in impaction state, the action reed of the first sensitive switch 7 is positioned at impaction state, thus the first sensitive switch 7, second sensitive switch 8 is all connected, now load is started working, and drive motors 3 is also started working simultaneously; During timing, drive motors 3 driving timing gear train 4 operates, thus drive main shaft 2 to rotate by transition gear 5, main shaft 2 is with moving cam 6 to rotate, at the end of setting timing, described cam 6 makes the action reed of the second sensitive switch 8 be in impaction state, the action reed of the first sensitive switch 7 is positioned at relaxation state, thus the second sensitive switch 8 is connected and the first sensitive switch 7 disconnects, and now drive motors 3 and load all quits work.
