With the automatic milk punching machine of water storage measuring ability
Technical field
The utility model relates to a kind of automatic coffee making equipment, particularly a kind of automatic milk punching machine with water storage measuring ability.
Background technology
Existing automatic milk punching machine is equipped with storage tank and the Magnetic Induction switch for sensed water level situation, Magnetic Induction switch comprises the electronics tongue tube be connected in control circuit and the magnetic float be arranged in storage tank, magnetic float is spacing is arranged on bottom in storage tank, and it is outer and be fixed on the side at magnetic float upper limit place that electronics tongue tube is positioned at storage tank.When storage tank is in place and has enough water, magnetic float floats up to upper limit place, the magnetic triggerable electronic tongue tube of magnetic float, and electronics tongue tube provides normal signal to circuit; When water level is not enough or when storage tank is not in place, magnetic float is failed near electronics tongue tube, the non-inductive signal of electronics tongue tube, and control circuit is reported to the police.The magnetic float of this structure is installed complicated, moves up and down, and be positioned at storage tank bottom because magnetic float is limited in a very little space, therefore, the easy collect dirt in magnetic float installation site and dirt are difficult to cleaning, cause bacteria breed, there is larger health concerns; In addition, once after magnetic float installed position gathers incrustation scale or other dirt, magnetic float is easily stuck, thus affects the normal detection of water level; Further, magnetic float long period of soaking is in water, and its inner magnetic patch exists larger risk of making moist, so that the magnetic abatement of magnetic patch, affects the normal work of electronics tongue tube.
Utility model content
The purpose of this utility model is to provide a kind of simple and reasonable for structure, and the cleaning of reliable operation, water level accuracy of judgement, storage tank is easy to the automatic milk punching machine of band water storage measuring ability, to overcome the deficiencies in the prior art.
The purpose of this utility model is achieved in that
A kind of automatic milk punching machine with water storage measuring ability, comprise automatic milk punching machine body, automatic milk punching machine body is provided with storage tank and control circuit, it is characterized in that: the outer bottom of the corresponding storage tank of described automatic milk punching machine body is provided with separation photoelectric level transducer, separation photoelectric level transducer and control circuit are electrically connected, the at least corresponding photoelectric level transducer place that is separated of storage tank is provided with transparency window, and transparency window is provided with printing opacity projection.
The purpose of this utility model can also adopt following technical measures to solve:
As scheme more specifically, described printing opacity projection is in tapered and be wholely set at storage tank inner surface; Described separation photoelectric level transducer comprises the light-emitting tube, light receiving tube and the control module that are mutually electrically connected, and light-emitting tube and light receiving tube are positioned at the center line both sides of printing opacity projection.
The transparent window of the corresponding storage tank of described automatic milk punching machine body is provided with perforate, is provided with deck inside perforate, and be separated photoelectric level transducer and buckle in deck, its installation is extremely convenient.
Be provided with lack of water warning circuit in described control circuit, when storage tank be not in place or water storage tank water level lower than setting value time, lack of water warning circuit start, with timely reminding user.
Described storage tank and the split of automatic milk punching machine body are arranged.
Described storage tank is arranged on the automatic milk punching machine body back side, and the corresponding storage tank in the automatic milk punching machine body back side is provided with location storage cavity, is separated photoelectric level transducer and is arranged on location storage cavity madial wall.
The beneficial effects of the utility model are as follows:
The automatic milk punching machine of this kind of band water storage measuring ability utilizes and is separated the water level situation that photoelectric level transducer judges storage tank, and by control circuit that it is fed back by voltage signal, to further process, it compared with prior art, movable members as magnetic float and so on need not be set in storage tank, to make it not exist because movable members is stuck and cannot the phenomenon of detecting water level occur, meanwhile, the labyrinth that it also avoid because of movable members installation site cause gathering of dirt and clean difficulty large etc. not enough.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
See shown in Fig. 1 to Fig. 3, a kind of automatic milk punching machine with water storage measuring ability, comprise automatic milk punching machine body 1, automatic milk punching machine body 1 is provided with storage tank 3 and control circuit, the outer bottom of described automatic milk punching machine body 1 corresponding storage tank 3 is provided with and is separated photoelectric level transducer 2, be separated photoelectric level transducer 2 to be electrically connected with control circuit, at least corresponding photoelectric level transducer 2 place that is separated of storage tank 3 is provided with transparency window (in the present embodiment, whole storage tank 3 is transparent material), and transparency window is provided with printing opacity projection 31.
Described printing opacity protruding 31 is tapered and is wholely set at storage tank 3 inner surface; Described separation photoelectric level transducer 2 comprises the light-emitting tube 22, light receiving tube 23 and the control module 21 that are mutually electrically connected, and light-emitting tube 22 and light receiving tube 23 are positioned at the center line both sides of printing opacity projection.
The transparent window of the corresponding storage tank 3 of described automatic milk punching machine body 1 is provided with perforate, is provided with deck 11 inside perforate, is separated photoelectric level transducer 2 and buckles in deck 11.
Lack of water warning circuit is provided with in described control circuit.
Described storage tank 3 is arranged with automatic milk punching machine body 1 split.
Described storage tank 3 is arranged on automatic milk punching machine body 1 back side, and the corresponding storage tank 3 in automatic milk punching machine body 1 back side is provided with location storage cavity 12, is separated photoelectric level transducer 2 and is arranged on location storage cavity 12 madial wall.
Its operation principle is: when water storage tank water level exceedes critical groundwater table and floods the printing opacity projection 31 of storage tank 3 inner surface, the light that the light-emitting tube 22 being separated photoelectric level transducer 2 emits exposes on the conical surface of printing opacity projection 31, owing to forming interface between water and printing opacity projection 31, so, the light that light-emitting tube 22 emits will through the conical reflecting of printing opacity projection 31 to light receiving tube 23, control module 21 output LOW voltage signal, lack of water warning circuit is in closed condition; When storage tank 3 is in place, when water storage tank water level is lower than printing opacity projection 31, be separated light penetration printing opacity protruding 31 that the light-emitting tube 22 of photoelectric level transducer 2 emits and do not reflex to light receiving tube 23, control module 21 output HIGH voltage signal, and lack of water warning circuit sends warning; When storage tank 3 leaves automatic milk punching machine body 1, be separated light penetration printing opacity protruding 31 that the light-emitting tube 22 of photoelectric level transducer 2 emits and do not reflex to light receiving tube 23, control module 21 exports high level signal, and lack of water warning circuit sends warning.
