Specific embodiment

In the following, the utility model is described in detail in conjunction with attached drawing.

As seen in figures 3-6, a kind of coffee brewer is present embodiments provided, comprising: tea infuser cavity components 74, setting exist Scraping wafer sheet 73, first motor 51, the second motor 52, third motor 53 and connect with first motor 51 on upper bracket 90 First gear 61, the second gear 62 being connect with the second motor 52, the third gear 63 being connect with third motor 53, first gear 61 engage with the 4th gear 64, the 4th gear 64 is engaged with the 5th gear 65, and the rotation of the 5th gear 65 drives upper screw rod 71 to transport Dynamic, the movement of upper screw rod 71 drives the upper brew head 78 in tea infuser cavity components 74 to run, second gear 62 and the 6th gear 66 engagements, the 6th gear 66 are engaged with the 7th gear 67, and the rotation of the 7th gear 67 drives upper screw rod 78 to move, upper screw rod 78 Movement drives the lower brew head 79 in tea infuser cavity components 74 to run, and third gear 63 and is set to tea infuser cavity components 74 The eighth gear 68 of bottom engages, and the rotation of eighth gear 68 drives tea infuser cavity components 74 to rotate.

Above-mentioned coffee brewer, further includes: the coffee that 65 top of the 5th gear is connected to tea infuser cavity 80 is set and Water pipe 75.

Above-mentioned coffee brewer, further includes: for controlling the fine motion of the 5th gear 65 and 67 micro-adjustment of the 7th gear respectively Switch 76 and microswitch 77.

Coffee machine infuser is exactly that ground coffee is placed in coffee machine infuser, enters tea infuser by the water of high temperature and pressure In extract coffee, and stripped ground coffee is become into cake slag, is wiped off by scraping wafer sheet 73.

Specifically, first motor 51 drives first gear 61 to rotate, first gear 61 passes through the 4th gear 64, the 5th gear 65 transmissions drive upper screw rod 71 to move up and down, to drive upper 78 up and down motion of brew head

Second motor 52 drives second gear 62 to rotate, and second gear 62 passes through six gears 66,67 transmission belt of the 7th gear Dynamic upper screw rod 71 moves up and down, so that lower brew head 79 be driven to move up and down.

Third motor 53 works, and tea infuser cavity components 74 can be driven to rotate, and tea infuser cavity 80 is made to be located at charging position It sets or infusion position.

The feed location, i.e. tea infuser cavity 80 are moved downward in feed opening lower part, lower brew head 79, and ground coffee is direct Into tea infuser cavity 80.While brewing the rotation of cavity components 74, the silica gel being fixed on upper bracket 90 scrapes wafer sheet 73 punching Ground coffee outside bubbler cavity 80 is wiped off.

The infusion position, i.e. tea infuser cavity components 74 rotate the axial lower part of supreme brew head 78, upper brew head 78 to Under be moved into the top of tea infuser cavity 80, lower brew head 79 moves upwards, and squeezes ground coffee.The water of high temperature and pressure passes through undershoot It steeps head 79 and enters tea infuser cavity 80, Hot Coffee is discharged by upper brew head 78 in the coffee extracted.Brew end, upper brew head 78 move upwards, and leave tea infuser cavity 80 until lower brew head 79 moves upwards to 90 bottom of upper bracket, until arriving tea infuser The top of cavity 80 ejects a ground coffee blob of slag, at this point, third motor 53 works, the rotation of tea infuser cavity components 74 is extremely added Discharge position, while the silica gel on upper bracket 90 scrapes wafer sheet 73 and a coffee blob of slag is hung.Allow third motor more than 53 rotation several times, so as to Guarantee scrapes remaining coffee muffin completely.So far, brewing for coffee is completed, into next brewing process.Tea infuser cavity Whether component 74 has microswitch 76 and microswitch 77 can detecte to be rotated in place in each position.

In conclusion coffee brewer described in the present embodiment, by using motor driven substitution, cam is nibbled in the prior art Driving method is closed, the abrasion between part is reduced, the operation small structure of noise is simple, convenient for assembly and production.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
