As further shown in fig. 4, in one embodiment, backstop 15 is driven axially outwardly to limit the unseating of cup 51. The moving direction of the retaining piece 15 on the main machine 1 is the axial direction, when the processing cup body 51 is installed, the axially outward protruding retaining piece 15 can be pressed under the processing cup body 51 along the axial direction, and the axially outward protruding height of the retaining piece 15 is reduced, so that the processing cup body 51 can be smoothly assembled with the crushing cavity 11. When the food processor is in a working state, the retaining member 15 is limited to be protruded outwards, and the axial downward pressure on the retaining member 15 can not make the retaining member 15 fall back, so that the position of the processing cup body 51 is limited.

In a specific embodiment, the driving structure of the retaining member 15 is as disclosed in the previous embodiments, which is not described herein, and in contrast, the moving direction of the electromagnet ejector rod is axial up and down movement, and meanwhile, a guiding inclined plane is provided between the electromagnet ejector rod and the retaining member 15, so that the moving direction of the retaining member 15 is radial horizontal movement under the driving action of the electromagnet ejector rod, the processing cup body 51 is provided with a retaining cavity 5105 in the radial direction for the retaining member 15 to insert, and the processing cup body 51 cannot be retracted in the state that the retaining member 15 is inserted into the retaining cavity 5105. As in the previous embodiment, the retaining link 5102 is disposed in the retaining cavity 5105, and the radially moving retaining member 15 can axially limit the retaining link 5102 in the retaining groove 5301 of the cup lid 53 by the action of the guide slope, so as to achieve retaining of the cup lid 53. Further, the retaining cavity 5105 can be provided with a gear (such as a retaining rib or a retaining wall located below the retaining piece 15) along the axial direction of the processing cup body 51, so that when the retaining piece 15 extends into the retaining cavity 5105, axial limitation on the processing cup body 51 can be formed, and the locking reliability of the processing cup body 51 is improved.

As further shown in fig. 7 and 8, the retaining groove 5301 has an axial opening into which the retaining link 5102 is inserted, the retaining member 15 is movably disposed on an end surface of the main body 1, and the retaining member 15 is capable of axially retaining the retaining link 5102 in the retaining groove 5301 in an operating state of the food processor. The axial motion structure can reduce the space occupation in the processing cup assembly 5, and the stopping of the cup cover 53 can be realized only by reserving the cavity of the axial displacement of the stopping connecting rod 5102. In one embodiment, the lid 53 is screwed with the processing cup 51, the screwing portion 5302 is disposed on a side portion of the lid 53, two screwing portions 5302 are disposed on a side portion of the lid 53 at 180 ° symmetrically, meanwhile, the retaining groove 5301 is also disposed on a side portion of the lid 53 and located between the two screwing portions 5302, the lid 53 further has a triggering side edge 5303 for pressing the triggering link 5101, and the triggering side edge 5303 is provided with a guide surface in both screwing and unscrewing directions for facilitating guiding. The triggering side edge 5303 can press the switch link 14 on the host 1 through the triggering link 5101, so as to trigger the safety switch 13, and the retaining groove 5301 is arranged behind the triggering side edge 5303 along the screwing direction of the cup cover 53. In the process of screwing the cup cover 53 and the processing cup body 51, the triggering side edge 5303 firstly presses the retaining connecting rod 5102 axially, the triggering connecting rod 5101 is pressed in the state of being screwed in place, the retaining connecting rod 5102 is reset in the retaining groove 5301, at the moment, the retaining connecting rod 5102 is still in the axially telescopic state relative to the retaining groove 5301, and only when the food processor is in the working state, the retaining connecting rod 5102 is limited in the retaining groove 5301. Under the state that the cup cover is screwed in place, the bottom surface of the retaining groove 5301 is in clearance fit with the upper end of the retaining connecting rod 5102, the clearance A is more than 0.5mm, meanwhile, the distance B between the bottom of the triggering side edge 5303 and the upper end of the retaining connecting rod 5102 is generally 1.5 mm-6 mm, the cup cover 53 can be forcibly unscrewed by the plastic deformation below 1.5mm and exceeding 3N, and the hand feeling of leading-in and screwing-out is poor by being higher than 6 mm.

As further shown in fig. 11, in order to improve the connection reliability between the cup lid 53 and the processing cup 51, the processing cup 51 has a screwing groove 5107, the triggering side edge 5303 can be screwed into the screwing groove 5107 along the circumferential direction to press the triggering connecting rod 5101, and the triggering side edge 5303 protrudes radially outward to be axially limited in the screwing groove 5107. The screwing groove 5107 forms axial limit for the triggering side edge 5303, so that the triggering side edge 5303 and the screwing groove 5107 can only be matched, screwed and screwed out in the circumferential direction, and therefore the up-and-down displacement of the cup cover 53 is limited. When assembling the cup cover 53, for avoiding triggering the unilateral assembly of side edge 5303 and leading to the problem of inaccurate installation of cup cover 53, in a specific embodiment, the width of screw-in groove 5107 sets up to C and is less than or equal to 4mm, simultaneously, in order to make the oblique dress in the time the cup cover 53 can pop out smoothly through elasticity, the triggering side edge 5303 maximum dimension D during the slope requires to be less than 0.3mm than screw-in groove 5107 width C more than, all adopt the fillet transition inside and outside simultaneously, make easy pop out the cup cover 53 when unilateral is packed into.

Alternatively, the retaining groove 5301 has a radial opening into which the retaining link 5102 is inserted, the retaining member 15 is movably disposed on an end surface of the main body 1, and the retaining member 15 can radially position the retaining link 5102 within the retaining groove 5301 in an operating state of the food processor. The radial movement structure not only forms circumferential locking on the cup cover 53, but also can realize axial locking on the cup cover 53 according to the change of the arrangement structure, thereby avoiding the problem that the cup cover 53 shakes up and down to separate from the cup body due to working vibration. In one embodiment, lid 53 is rotatably engaged with cup 51, rotating portion 5302 is disposed on the side edge of lid 53, and retaining groove 5301 is also disposed on the side edge of lid 53, lid 53 further has triggering side edge 5303 for pressing triggering link 5101, triggering side edge 5303 can press switch link 14 on host 1 through triggering link 5101 to trigger safety switch 13, retaining groove 5301 is disposed behind triggering side edge 5303 in the rotating direction of lid 53, retaining groove 5301 is radially opened along the side of lid 53, retaining link 5102 can be radially moved by triggering of retaining member 15 (e.g., radial guide groove is disposed in cup 51 for moving retaining link 5102, or a fixed rotating shaft is disposed in cup 51, a position between the upper and lower ends of retaining link 5102 can be rotated along the rotating shaft, retaining member 15 drives the lower end of retaining link 5102 to radially move, correspondingly, the upper end of the backstop connecting rod 5102 moves radially in the opposite direction under the action of the rotating shaft), and is inserted into the backstop groove 5301 with a radial opening, so that backstop limitation is realized. It can be understood by those skilled in the art that, for stopping the cup lid 53, a power supply structure may be additionally disposed on the processing cup 51, and a structure similar to the aforementioned stopping member 15 is used to limit the retreat of the cup lid 53, which is not described herein again.

As further shown in fig. 3, if the stopping effect of the stopping member 15 is earlier than the triggering of the safety switch 13, the processing cup assembly 5 may start to operate without being installed, which may cause a large safety hazard, therefore, in order to achieve at least the locking effect of the stopping member before the triggering of the safety switch 13, in one embodiment, the processing cup assembly 5 is screwed to the crushing cavity 11, and the stopping link 5102 and the triggering link 5101 are sequentially arranged on the same circumference along the screwing direction of the processing cup assembly 5, so as to sequentially press the stopping member 15 and the switch link 14 in the screwing process, and the stopping member 15 is enabled to take effect only after the processing cup 51 reaches the position where the switch link 14 is pressed. Thus, the trigger of the safety switch 13 forms a necessary condition for the operation of the stopper 15, and the stopper 15 and the stopper link 5102 can perform the stopper function only after the trigger of the safety switch 13. It will be appreciated that in some embodiments, the backstop 15 is not immediately effective after the safety switch 13 is triggered, but rather locks the processing cup assembly 5 when the user initiates the corresponding pulping process after pressing a particular processing instruction. If the machining is scheduled, the machining cup assembly 5 is locked when the machining program is started after the scheduled time is reached.

Alternatively, the retaining link 5102 and the triggering link 5101 may be sequentially arranged at different circumferences, and correspondingly, the switch link 14 and the retaining member 15 on the main body 1 are also sequentially arranged at different circumferences, so as to ensure that the retaining member 15 and the switch link 14 are sequentially pressed in the screwing process.

Alternatively, the locking effect of the retaining assembly is not prior to the triggering of the safety switch 13, and the retaining assembly and the safety switch 13 may be activated simultaneously. Specifically, the retaining link 5102 and the triggering link 5101 are arranged in parallel in the same radial direction of the processing cup assembly 5, and correspondingly, the switch link 14 and the retaining member 15 on the main machine 1 are also arranged in parallel in the same radial direction, so that the retaining member 15 and the switch link 14 are pressed in the installation process of the processing cup assembly 5 and the crushing cavity 11.

Further, as shown in fig. 3, a limiting member 16 forming a limiting groove 1601 is further disposed on the upper end surface of the host 1, the width of the limiting groove 1601 is adapted to the outer diameter of the trigger link 5101, and the switch link 14 is disposed in the limiting groove 1601, so as to ensure that, under a normal condition, only the trigger link 5101 is allowed to enter the limiting groove 1601, and the switch link 14 is pressed to trigger the safety switch 13, thereby preventing a user from accidentally triggering the safety switch 13. Furthermore, the limiting groove 1601 is set to be higher than the switch connecting rod 14, the switch connecting rod 14 is hidden in the limiting groove 1601, no matter from the axial direction or the screwing direction, the external device with the size larger than the limiting groove 1601 can not trigger the safety switch 13, meanwhile, the human body false triggering can be avoided, and the use safety is improved. In one embodiment, the limiting member 16 is a protrusion disposed on the upper end surface of the host 1, the two protrusions are disposed in parallel along the same radial direction, a limiting groove 1601 is formed between the two protrusions, and the limiting groove 1601 is disposed along the arc-shaped movement track of the trigger link 5101.

As shown in fig. 1-9, 15 and 16, in one embodiment, the food processor with an optimized assembly structure comprises a main body 1, wherein the main body 1 is provided with a crushing cavity 11 with an upper opening, and the crushing cavity 11 is provided with a crushing cutter group 12; food preparation machine still includes that detachable installs in the processing cup subassembly 5 of smashing the chamber 11 top, and processing cup subassembly 5 includes processing cup 51 and sets up in the processing knife tackle 52 of processing cup 51, and processing knife tackle 52 can install under the state of smashing chamber 11 with smashing knife tackle 12 transmission and be connected processing cup 51 and smashing chamber 11 and pass through locking structure fastening connection, still is equipped with shock-absorbing structure between processing cup 51 and the crushing chamber 11. Wherein, the lower cup 7 that is fixed in host computer 1 forms crushing chamber 11, and lower cup 7 has the axial installation department of evading in host computer 1 terminal surface to set up spinner 71 in the circumference of installation department, processing cup 51 has the end edge that the installation department is connected, and end edge sets up along the inner wall and detains along 5108, can with spinner 71 fixed connection of lower cup 7, spinner 71 and detain along 5108 can close in order to form the locking structure soon. It is understood that the button edge 5108 and the button 71 may be disposed on the mounting portion and the bottom edge, respectively, as desired. Through the cooperation of the turnbuckle 71 and the buckle edge 5108, the rapid assembly of the processing cup assembly 5 and the crushing cavity 11 can be realized, and the installation efficiency is improved.

For installing processing cup subassembly 5 in smashing chamber 11 when traditional food preparation machine's processing cup 51 and smashing the installation of cup, it is spacing that processing cup subassembly 5 periphery and the vortex muscle in smashing chamber 11 realize circumference, but processing cup subassembly 5 lacks the axial spacingly with lower cup 7, leads to the condition that processing cup subassembly 5 jumped the cup easily to take place. And the motor in the main machine 1 can generate violent vibration in the process of driving the crushing cutter set 12 or the processing cutter set 52 to rotate, so that the vibration noise generated between the processing cup assembly 5 arranged above the crushing cavity 11 and the lower cup body 7 is large. Through installing processing cup subassembly 5 in crushing chamber 11 top, can effectually increase the volume of processing cup subassembly 5 through configuration optimization to utilize processing cup subassembly 5 and the locking structure between the lower cup 7 that forms crushing chamber 11 to realize processing cup subassembly 5 and the axial locking of lower cup 7 fixed, solved the problem that processing cup subassembly 5 jumped the cup, the two is connected more reliably.

The number of the shock absorbing members 5109 is preferably six, the shock absorbing members are arranged at uniform angles with circumferential intervals of 60 degrees, due to the fact that noise between the processing cup body 51 and the crushing cavity 11 mainly lies in vibration noise generated when the processing cup body 51 axially collides with the upper port of the crushing cavity 11, the shock absorbing members 5109 are arranged at the bottom of the processing cup body 51 and are circumferentially and uniformly distributed, vibration collision in the axial direction can be buffered when the shock absorbing members are abutted against the upper port of the crushing cavity 11, and the generated noise is further reduced. According to the actual structure, the damper 5109 may be disposed in a recess defined by the bottom edge of the bottom of the processing cup 51, and the upper port of the pulverization chamber 11 may extend into the recess to abut against the damper 5109. The shape of the shock absorbing member 5109 is not limited to a semicircular arc shape, a circular shape, a rectangular shape and the like, and the width E of the shock absorbing member 5109 can be set between 5mm and 25mm, so that the shock absorbing member can be pressed with the crushing cavity 11 to realize buffering.

Meanwhile, the angle between the single shock absorption piece 5109 and the middle part of the locking structure can be set between 10 degrees and 25 degrees, and the angle is larger than 10 degrees, so that the mold stripping requirement is met.

Further, in order to ensure the support of the damper 5109 to the locking structure, the locking structure is disposed between two adjacent damper 5109 distributed along the circumferential direction. When the angle between the shock absorbing pieces 5109 and the middle part of the locking structure is smaller than 25 degrees, the two shock absorbing pieces 5109 can realize the fulcrum effect on the middle locking structure, and the support of the shock absorbing pieces 5109 on the middle locking structure can be weakened due to the fact that the angle is too large, so that the locking structure is prone to loosening. Can inject the locking size of locking structure at 12 ~ 35mm to guarantee the locking reliability.

The fixing reliability of the shock absorbing member 5109 can be improved through the mounting groove 5110, and the problem that the shock absorbing member 5109 is fixed and loosened due to vibration is solved.

Further, as shown in fig. 18 and 19, a clamping hole 5111 is formed in the bottom surface of the mounting groove 5110, and the shock absorbing member 5109 can be clamped into the clamping hole 5111 to form axial limit with the mounting groove 5110.

As shown in fig. 1-9 and 20, in one embodiment, the food processor with an optimized assembly structure comprises a main body 1 with a built-in motor, wherein the main body 1 is provided with a crushing cavity 11 with an upper opening, and the crushing cavity 11 is provided with a crushing cutter group 12; food preparation machine still includes that detachable installs in the processing cup subassembly 5 of smashing the chamber 11 top, and processing cup subassembly 5 includes processing cup 51, sets up in processing cup 51's processing knife tackle 52 and installs in processing cup 51's bowl cover 53, and processing knife tackle 52 can be installed under the state of smashing chamber 11 and is connected with the transmission of smashing knife tackle 12 at processing cup 51, and processing cup subassembly 5 is being located and smashes the chamber 11 top in the state of smashing chamber 11. The host 1 further comprises a power supply circuit, a detection circuit and a retaining assembly connected with the detection circuit, wherein the power supply circuit is connected with the motor and the retaining assembly and used for supplying power to the motor and the retaining assembly, the detection circuit is connected with the motor and the retaining assembly and used for acquiring state parameters of the motor, the retaining assembly is used for locking or unlocking the in-place installation states of the processing cup body 51 and the cup cover 53 according to the state parameters of the motor, and the in-place installation states of the processing cup body 51 and the crushing cavity 11.

Since the crushing cutter set 12 or the processing cutter set 52 in the food processor is driven to rotate in the same way when the motor is in a rotating state, the user opens the cup cover 53 to expose the processing cutter set 52, and when the user takes the processing cup assembly 5 out of the crushing cavity 11, the crushing cutter set 12 is exposed, in order to meet the requirement of safety regulations, the user should ensure that the processing cutter set 52 is in a static state when the user opens the cup cover 53, or the processing cup assembly 5 is taken out of the crushing cavity 11, and the processing cutter set 52 is in a static state. Acquire the state parameter of motor through setting up detection circuitry, can further acquire the rotation state of smashing knife tackle 12 or processing knife tackle 52, if the motor still is in rotation state, then utilize the installation of the spacing processing cup 51 of stopping subassembly and bowl cover 53 state of targetting in place to make the user can't open bowl cover 53, and simultaneously, the installation of restriction processing cup 51 and crushing chamber 11 state of targetting in place, in order to make the user can't take off processing cup 51, avoid safe risk, ensure safe in utilization.

Furthermore, for more convenient acquisition of state parameters of the motor, the detection circuit comprises a first detection circuit for acquiring the supply current of the motor, the first detection circuit comprises a current detection module for acquiring the supply current of the motor and a first processing module for judging whether the supply current of the motor is within a preset range value i, the motor is in a stalling state when the supply current is within the preset range value, and the stopping assembly is in a locking state when the supply current of the motor is outside the preset range value. The current detection module can be a current sensor, such as a common hall current sensor, and acquires a specific current value; the first processing module is a processor such as a single chip microcomputer or a PLC and the like to execute the function of judging the current magnitude. The power supply circuit can supply power to the motor with locked-rotor current at the initial stage, the motor can only be rotated when the current meets the requirement of the driving motor, and in the process, the current value of the driving motor is a range value, and whether the motor is in a working state or not can be judged according to the magnitude of the power supply current of the motor. If the continuous power supply current in a certain period of time is outside the preset range value, the motor is in a rotating state, the retaining assembly keeps locking the processing cup assembly 5, and the processing cup body 51 is prevented from being opened by a user or the processing cup body 51 is prevented from being taken down by the user.

Further, the preset range value of the power supply current of the motor is 0-n milliamperes. According to the magnitude of the power supply current of the motor obtained by the first detection circuit, when the power supply current is larger than n milliamperes, the motor is confirmed to be in a rotating state, and the specific value of n depends on the influences of different motor types, the current load of the motor and other factors. It should be noted that, when the power supply current of the motor is 0, it is necessary to further determine that the current motor is in a complete stalling state after power failure, or in an inertial rotating state after power failure.

Considering that the motor still rotates due to inertia after being powered off, in one embodiment, the detection circuit further comprises a second detection circuit for acquiring the rotation speed of the motor, the second detection circuit comprises a rotation speed detection module for acquiring the rotation speed of the motor and a second processing module for judging whether the rotation speed of the motor is 0, and the anti-return assembly can be in a locked state when the rotation speed of the motor is not 0.

If the rotating speed of the motor is 0, the crushing cutter group 12 and the processing cutter group 52 which are in transmission connection with the motor are both in a stop state, the stopping assembly can be unlocked to allow the cup cover 53 to be opened, or the processing cup body 51 to be taken down, otherwise, if the rotating speed of the motor is not 0, the stopping assembly keeps locking the processing cup assembly 5, and the processing cup body 51 is prevented from being opened or the processing cup body 51 is prevented from being taken down accidentally by a user. Whether the processing cutter set 52 and the crushing cutter set 12 stop rotating or not is judged according to the rotating speed of the motor, the detection reference is more visual, and the obtained result is more reliable. The detection of the power supply current of the motor in the embodiment is matched, so that the use safety of a user is further ensured.

In one embodiment, the power supply circuit comprises a first power supply circuit connected with the motor, a second power supply circuit connected with the retaining assembly, and a delay circuit respectively connected with the first power supply circuit and the second power supply circuit, wherein the delay circuit is used for delaying disconnection of the second power supply circuit after disconnection of the first power supply circuit so as to delay unlocking of the retaining assembly. The motor and the stopping assembly adopt independent power supply circuits, if a user disconnects a first power supply circuit to stop the food processing machine, the circuit of the stopping assembly still keeps a passage, under the action of the stopping assembly, the user can not directly take off the processing cup body 51 or open the cup cover 53, after a delay circuit obtains a signal that the first power supply circuit is disconnected, a second power supply circuit of the stopping assembly is disconnected after a certain time, sufficient time is reserved for the inertial rotation stopping of the motor, the stopping assembly continuously keeps the locking state of the cup cover 53 and the processing cup body 51 during the period, and the processing knife set 52 and the crushing knife set 12 are both in the stopping state when the user opens the cup cover 53 or takes off the processing cup body 51 after the stopping assembly is powered off. In a specific embodiment, the time for the delay circuit to delay the disconnection of the second power supply circuit is 5s, so as to ensure that the processing cutter group 52 and the crushing cutter group 12 are in a completely static state, it can be understood that the delay time of the delay circuit can also be adjusted, and in general, the delay time t can effectively reduce the safety risk and improve the use safety within the range that t is more than or equal to 1.5s and less than or equal to 10 s.

In one embodiment, processing cup 51 has a threaded groove 5107 that mates with lid 53, lid 53 being axially restrained within threaded groove 5107, and trigger link 5101 is located at the end of threaded groove 5107 in the direction of threading of lid 53 to processing cup 51.
