The micro-switch of the micro-motion mechanism is closed by the cup cover pressing on the connecting rod, and the stirring and heating functions of the multifunctional food processor are realized by powering on after the micro-motion mechanism is closed. When the human body sensor senses that someone is in front of the multifunctional food processor, the electronic scale circuit on the electronic scale printed circuit board is activated, so that the electronic scale assembly works normally, regardless of whether the micro-switch of the micro-motion mechanism is closed.

[0008] According to a preferred aspect of the present invention, when the electronic scale assembly is operating normally, when the cup lid is opened, if the body assembly and / or the cup assembly is tilted relative to the correct position, the weight sensor of the electronic scale assembly senses the change in weight and transmits a signal to the person so that the person can correct the incorrect placement of the body assembly and / or the cup assembly.

[0009] According to a preferred aspect of the present invention, when the electronic scale assembly is operating normally, when the cup lid is closed, if the body assembly and / or the cup assembly is tilted or tipped over during operation, the weight sensor of the electronic scale assembly senses the weight change and transmits a signal to the multi-function food processor to stop all operations of the multi-function food processor.

[0010] According to a preferred aspect of the present invention, when a person is outside the sensing range of the human body sensor, the electronic scale circuit is not activated, and when a person is within the sensing range of the human body sensor, the electronic scale circuit is activated.

[0011] According to a preferred aspect of the present invention, the signal is an alarm signal, a vibration signal or an optical signal.

[0017] Compared with the prior art, the multifunctional food processor of the present invention has the following beneficial effects. The multifunctional food processor of the present invention can prevent and avoid unnecessary damage and harm to the machine and people caused by the incorrect placement of its own components when the multifunctional food processor is working and starting up, thereby enhancing the overall safety of the multifunctional food processor. In addition, since the electronic scale assembly has fewer components, it is convenient to install. Furthermore, since the electronic scale assembly only works when someone is in front of the multifunctional food processor, it can save energy and extend its own life. Therefore, the multifunctional food processor of the present invention has the effects of safe use, convenient installation, and energy saving.

Other features, objects and advantages of the present invention can be clearly seen from these descriptions, drawings and claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be described in more detail below in conjunction with specific embodiments. It should be understood by those skilled in the art that these descriptions merely list some specific embodiments of the present invention and do not limit the present invention and its protection scope in any way.

[0025] Additionally, when introducing elements of various embodiments of the present application, the articles “a,” “an,” “the,” and “said” are intended to mean that there are one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements besides the listed elements.

[0026] like Figure 1 As clearly shown in the figure, an exploded stereoscopic schematic diagram of a cup assembly and a body assembly of a multifunctional food processor according to an embodiment of the present invention is provided. The multifunctional food processor has stirring, heating and electronic scale functions. Specifically, the multifunctional food processor mainly includes a body assembly, a cup assembly and an electronic scale assembly, wherein the body assembly is substantially composed of a body 201 and a base 202, and a display panel 206 is installed in a corresponding groove formed in the body 201. Various functions of the multifunctional food processor can be controlled by the display panel 206. In addition, the size of the display panel 206 can be 6 inches, 8 inches, 10 inches, or any suitable size that can clearly display the various functions of the food processor to the user.

[0027] In the cup assembly, the cup cover 102 is usually provided with a feeding hole 1021 at its center portion, so that food can be added to the stainless steel cup 107 through the feeding hole 1021 when the cup cover 102 is closed. In addition, the feeding hole 1021 also allows steam to be discharged when the food in the stainless steel cup 107 is heated. At the same time, in order to prevent the food in the stainless steel cup 107 from overflowing during heating, an anti-overflow cover can also be inserted into the feeding hole. The anti-overflow cover can be a hollow cylinder with a top so that it can be used as a measuring cup, such as a transparent measuring cup 101. A waterproof ring (not shown) can be inserted between the stainless steel cup 107 and the cup cover 102 to achieve sealing.

[0028] The stainless steel cup 107 is placed in the central recess of the body 201 and a blade is arranged therein, and a driving motor and a transmission mechanism may be arranged in the body assembly, wherein the rotation of the driving motor may be transmitted to the blade through the transmission mechanism, so that the blade processes and handles the food placed in the stainless steel cup 107, such as stirring and cutting. The transmission mechanism may be a pulley transmission mechanism, a gear transmission mechanism, etc. The blade is detachably mounted on the stainless steel cup 107 through a blade lock, and the blade lock may have a barrel and a lever, wherein the forward and reverse movements of the lever may realize the locking and removal of the blade on the stainless steel cup 107.

[0029] In addition, the stainless steel cup 107 is symmetrically provided with two handles 106 on the outside, wherein the handle 106 can be fixed to the side of the stainless steel cup 107 by a fixing device and is installed with a handle cover 103. The fixing device can be a screw covered with a screw cover 105. A channel is formed between the side of the stainless steel cup 107 and the handle 106, and the channel can be mainly formed by the hollow of the handle 106, and the connecting rod 104 can be located in the channel. The fuselage assembly is provided with two micro-mechanisms corresponding to the two connecting rods 104, and each micro-mechanism includes a switch top rod 203, a micro-switch 205, and a micro-switch fixing frame 204 for fixing the micro-switch 205, wherein the switch top rod 203 is installed on the fuselage 201, and the micro-switch 205 and the micro-switch fixing frame 204 are arranged on the base 202. The power control printed circuit board 207 is also arranged on the base 202.

[0030] The micro-motion mechanism can be triggered by the cup cover 102 pressing on the connecting rod 104, and the stirring and heating functions of the multi-function food processor can be powered on and realized only after the micro-motion mechanism is closed (and therefore the circuit on the power control printed circuit board 207 is connected). In contrast, when the cup cover 102 is opened, the circuit on the power control printed circuit board 207 is disconnected, and the stirring and heating functions stop.

[0031] In addition, the bottom of the stainless steel cup 107 may be provided with a heating device, which can be heated by supplying power to the heating device. The heating device may include a heating film for heating, and a temperature control system is usually arranged on the heating film. The cup assembly also includes a bottom cover, such as a stainless steel bottom cover, which can be fixed to the bottom of the stainless steel cup 107 by welding so as to waterproof and seal the heating film and the temperature control system thereon. The cup bottom cover 108 can be fixed to the stainless steel bottom cover by screws.

[0032] Furthermore, the body assembly and the cup assembly contained therein can be detachably placed on the electronic scale assembly. The electronic scale assembly may include an electronic scale printed circuit board 302, four weight sensors (at Figure 1 Only two weight sensors 301 and 303 located on one side), a human body sensor 401 and a base for being placed on the working surface of the multi-function food processor are shown.

[0033] The strength of weight sensors 301 and 303 should be selected so that they can support the entire weight of the multi-function food processor in addition to the electronic scale assembly, and should also be able to support additional weight (e.g., the weight of the heaviest food that can typically be placed in stainless steel cup 107). In addition, four rubber feet made of rubber material or the like can be attached to the bottom of the base of the electronic scale assembly to provide support to the multi-function food processor and damping against impact.

[0034] In addition, the human sensor 401 may be, for example, a human proximity sensor, which is a sensor based on the microwave Doppler principle, with a planar antenna as a sensing system and a microprocessor as a control. When the human sensor 401 senses that someone is in front of the multi-function food processor, the electronic scale circuit on the electronic scale printed circuit board 302 is activated, so that the electronic scale assembly works normally, regardless of whether the micro switch 205 of the micro mechanism is closed. In particular, if Figure 2-4 As clearly shown in the figure, when the operator of the multi-function food processor (i.e., a person) is outside the sensing range of the human body sensor 401, the electronic scale circuit is not activated, and when the person is within the sensing range of the human body sensor 401, the electronic scale circuit is activated, regardless of whether the cup cover 102 is closed or opened.

[0035] That is to say, the electronic scale circuit is not activated by the closing and opening of the micro switch 205 but by the human body sensor 401 sensing that there is someone in front of the multi-function food processor. Therefore, as long as there is someone in front of the multi-function food processor, the electronic scale assembly can work normally regardless of whether the cup cover 102 is closed or opened.

[0036] When the electronic scale assembly is working normally, when the cup cover 102 is opened (i.e., the stirring and heating functions of the multi-function food processor are disabled), if the body assembly and / or the cup assembly are tilted relative to the correct placement, the four weight sensors 301 and 303 of the electronic scale assembly will sense the change in weight, and then send a signal to allow the operator to correct the incorrect placement of the body assembly and / or the cup assembly, so as to avoid unnecessary damage to the multi-function food processor when it is turned on, and to avoid harm to the operator. The signal can be an alarm signal, a vibration signal, an optical signal, etc.

[0037] In addition, when the electronic scale assembly is working normally, when the cup cover 102 is closed (i.e., the stirring and heating functions of the multi-function food processor are enabled), if the body assembly and / or the cup assembly is tilted or tipped over during operation, the four weight sensors 301 and 303 of the electronic scale assembly will sense the change in weight and send out a signal to stop all operations of the multi-function food processor, thereby preventing damage to the multi-function food processor and protecting the safety of the operator.

[0038] The above-mentioned food processor may further include other necessary components for realizing its functions (eg, electrical connection, operation control, etc.), which are well known to those skilled in the art and will not be described in detail herein.

[0039] Compared with the prior art, the multifunctional food processor of the present invention has the following beneficial effects. The multifunctional food processor of the present invention can prevent and avoid unnecessary damage and harm to the machine and people caused by the incorrect placement of its own components when the multifunctional food processor is working and starting up, thereby enhancing the overall safety of the multifunctional food processor. In addition, since the electronic scale assembly has fewer components, it is convenient to install. Furthermore, since the electronic scale assembly only works when someone is in front of the multifunctional food processor, it can save energy and extend its own life. Therefore, the multifunctional food processor of the present invention has the effects of safe use, convenient installation, and energy saving.

[0040] The above description is only used to exemplify the present invention and is not used to limit the present invention. It should be pointed out that for ordinary technicians in this field, several improvements, modifications and variations can be made to the present invention, but these improvements, modifications and variations should be regarded as falling within the scope of protection of the present invention without departing from the spirit of the present invention.
