Description

Food processor capable of detecting filter screen Technical Field The invention relates to the technical field of food processing devices, in particular to a food processor capable of detecting a filter screen. Background At present, food processing machines on the market become more and more various and intelligent, along with the improvement of living standard, the performance of a user on a food processor is higher and higher, for no-hand washing series, the wall breaking and filtering-free function can be realized for the pulping function, and for the food processor, no-hand washing machine on the market has more and more functions, including a soybean milk function, a five-cereal function, a coffee function, a beancurd jelly function and the like, wherein a filter screen is required to be placed for realizing the corresponding function manufacturing for the coffee function and the beancurd jelly function. For example, coffee can be made, jellied bean curd can be made, and the operation can be completed by placing a filter screen. Meanwhile, in order to obtain a beverage with finer and better taste, the user selects the whole machine to discharge the slurry and simultaneously places the filter screen on the slurry cup to finish one-time filtration. However, the filter screen that does not wash series food processor with hand on the market at present can't realize filter screen detection function, and when the beverage that the corresponding function can be accomplished to the preparation must be placed to the filter screen of user's selection, because unable detection has to place the filter screen in the operation process, the filter screen of leaking can lead to making the beverage to fail to lead to user experience poor. Secondly, the current detection of the pulp receiving cup mainly comprises two types, namely a type of detecting the position of the pulp receiving cup by directly detecting a magnet on the pulp receiving cup and a type of indirectly detecting the pulp receiving cup by detecting a magnet on a cover of the pulp receiving cup. For the second detection, in the prior art, when the user places the filter screen, the user cannot place the pulp cup cover any more, so that the detection of the pulp receiving cup cannot be realized, the corresponding function cannot be realized, and the use scene is limited. Disclosure of Invention The invention aims to provide a food processor capable of detecting a filter screen, which is used for solving the problem that the existing food processor cannot detect the filter screen. The invention provides a food processor capable of detecting a filter screen, which comprises a machine body, a pulping cavity arranged on the machine body, a liquid discharge valve with a liquid discharge nozzle, a control device and a pulp receiving container, wherein the pulp receiving container comprises a pulp receiving cup and a cup cover, the cup cover is provided with a pulp inlet corresponding to the liquid discharge nozzle, the cup cover is provided with a magnet, the cup cover is lapped on the pulp receiving cup to enable the magnet to be positioned at a first position, the food processor also comprises the filter screen, the filter screen is lapped on the pulp receiving cup and the cup cover is covered on the filter screen to enable the magnet to be positioned at a second position, the machine body is provided with a first detection device and a second detection device which are connected with the control device, when the magnet is positioned at the first position, the control device controls the liquid discharge valve to be opened according to a signal sensed by the first detection device, when the magnet is positioned at the second position, the first detection device is positioned in a signal shielding state, and the control device controls the liquid discharge valve to be opened according to a signal sensed by the second detection device. According to the food processor capable of detecting the filter screen, the magnet is arranged on the cup cover and has the first position and the second position, so that whether the filter screen is placed in the pulp receiving cup or not and whether the pulp receiving cup is placed in place or not can be indirectly judged according to the position of the magnet. The organism is equipped with first detection device and the second detection device who is connected with controlling means, and thereby the magnet is in first position, triggers first detection device and realizes connecing thick liquid cup and detect in place, and magnet is in the second position, and connect thick liquid cup, filter screen, bowl cover simultaneously exist and trigger second detection device promptly, and first detection device is in signal shielding state to indirectly realize that the filter screen, connect thick liquid cup to detect in place, the magnet discernment through the bowl cover has or not to place the filter screen promptly.
