Description

Mixer

Technical field

The invention relates to a fruit agitator.

Background technique

At present, most of the mixers use a contactable wired temperature measurement method, that is, there is a temperature sensing member on the heating cup, and the sensing seat on the motor seat has contact, the two must be in firm contact, and the contacts must be clean. This structure is defective, easy to contact, and requires power supply, which has hidden dangers.

At present, most of the mixers use a contactable water level detecting device and a contactable liquid overflow detecting device, which is a liquid contact between two conductors (generally food grade stainless steel), and detects whether there is current between the two conductors. Or to detect changes in the resistance values of the two conductor members to determine the water level. This method is defective, difficult to clean, and difficult to seal. If liquid overflows or does not dry thoroughly after cleaning, it may easily lead to short circuit.

Summary of the invention

Accordingly, it is an object of the present invention to provide a non-contact wireless temperature measurement and liquid overflow induction agitator.

The object of the invention is achieved in this way.

A mixer comprising a circuit control board, a cup cover, a cup body and a motor seat, the cup cover is provided with a first passive RF tag, a second passive RF tag is arranged at the bottom of the cup body, and the motor seat is provided with an RF The tag reader/writer, the first passive RF tag and the second passive RF tag respectively establish wireless communication with the RF tag reader, and the RF tag reader and the signal are connected with the circuit control board.

The inner surface of the cup cover is provided with a liquid detecting device, and the liquid detecting device is connected to the first passive RF tag wire.

A passive magnetic-sensitive switching element is disposed around the cup cover, and the cup body is provided with a magnet capable of triggering a passive magnetic-sensitive switching element, and the passive magnetic-sensitive switching element is connected to the first passive RF tag wire.

The above technical solutions can also be further improved as follows.

The first passive RF tag, the second passive RF tag, and the passive magnetically sensitive switching element are both sealed and waterproof.

The magnet is provided on the handle of the cup.

The passive magnetically sensitive switching element is a dry manifold or a magnetic manifold.

The RF tag reader is mounted directly on the circuit board.

The invention can accurately detect the position of the lid and the lid of the lid, and can accurately detect the water level and foam overflow in the cup body. Thanks to the wireless communication technology, the lid and cup can be directly washed or even soaked in water.

Figure 1 is a schematic view of the structure of the present invention.

Detailed ways

The invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Embodiments, in conjunction with the accompanying drawings, a mixer comprising a circuit control board 1, a cup cover 2, a cup body 3 and a motor base 4, the cup cover 2 is provided with a first passive RF tag 5, and the bottom of the cup body 3 is provided There is a second passive RF tag 6, and the motor base 4 is provided with an RF tag reader/writer 7, and the first passive RF tag 5 and the second passive RF tag 6 establish wireless communication with the RF tag reader/writer 7, respectively. The RF tag reader/writer 7 is signally coupled to the circuit board 1 or directly integrates the RF tag reader to the circuit board.

The inner surface of the lid 2 is provided with a liquid detecting device 8, and the liquid detecting device 8 is electrically connected to the first passive RF tag 5.

A passive magnetic-sensitive switching element 9 is disposed around the cup cover 2, and the passive magnetic-sensitive switching element is a dry tube or a magnetic tube. The cup 3 is provided with a magnet on the handle that can trigger the action of the passive magnetic-sensitive switching element 9. 10. The passive magnetically sensitive switching element is coupled to the first passive RF tag wire.

The first passive RF tag, the second passive RF tag, the passive magnetic sensitive switching element, and the like need to be sealed and waterproof. The circuit control board controls the RF tag reader to transmit the queried wireless carrier signal through the antenna above the reader, and the first passive RF tag and the second passive RF tag respectively receive the RF tag through the antenna on the tag The carrier signal sent by the reader and converted into a DC signal to power the entire chip. At the same time, the first passive RF tag and the demodulation module on the second passive RF tag demodulate the query information carried by the modulated carrier signal, and transmit the query information to the corresponding first passive tag RF or the second passive RF tag. The baseband portion of the upper chip is processed. After the baseband portion of the first passive RF tag demodulates the query information carried by the modulated carrier signal, the cup cover cover signal, the cup cover position signal and the liquid overflow signal are sensed in time, and then the modulation module on the label is reversed. The detected cup lid closing signal, the lid position signal and the liquid overflow signal are returned to the RF tag reader to complete a communication in the form of emission. After the baseband portion of the second passive RF tag demodulates the query information carried by the modulated carrier signal, the induced temperature signal is processed in time, and then the modulation module on the second passive RF tag transmits the signal in the form of reverse transmission. The incoming temperature signal is returned to the RF tag reader for a communication. Since the total number of the first passive RF tag and the second passive RF tag exceeds two, the RF tag reader/writer must perform anti-collision processing, and the specific anti-collision algorithm can be determined according to actual test conditions. The RF tag reader will receive the first passive RF tag reversely launched cup cover, the cover position and the liquid overflow carrier signal and the second passive RF tag reversely transmitted temperature carrier signal through the RF The demodulation module of the tag reader demodulates the specific data and transmits it to the circuit control board. Through such two or more communications, the circuit board can fully obtain the lid of the lid, the position of the lid and the state of liquid spillage and the temperature of the liquid in the cup or cup.
