Similarly, since the airflow duct is in a blocking state, external dust cannot enter the motor installation cavity, and dust cannot be accumulated in the motor installation cavity, so that the heat dissipation effect of the motor assembly 22 is improved.

As shown in fig. 3 and 8, in the second state, a gap is formed between the stopper assembly 24 and the vent 23 to communicate the airflow duct with the outside. The air current that motor element 22 produced during operation can get into motor installation cavity inside through ventilation opening 23 to take out the produced heat of motor element 22 work, ensured the continuous heat dissipation of food preparation machine during operation, the electronic component in the food preparation machine is in effectual heat dissipation state, can improve its life.

In the installation process of the processing cup assembly 2 and the host 1, the stop assembly 24 can be driven to be switched from the first state to the first state, even if the airflow duct is switched from the closed state to the conduction state, external airflow can enter the airflow duct through the ventilation opening 23, and heat dissipation of the motor assembly 22 is further realized.

As shown in fig. 3-8, in some embodiments, the stop assembly 24 is movably disposed on the processing cup assembly 2. When processing cup subassembly 2 is installed on host computer 1, backstop subassembly 24 atress is in host computer 1, make backstop subassembly 24 switch over to the second state by the first state, for set up backstop subassembly 24 in host computer 1, set up backstop subassembly 24 in the protection of the inside motor installation cavity of processing cup subassembly 2 that realization that processing cup subassembly 2 can be better, avoid intaking, reduce the dust, and because the fixed relative stability of host computer 1 self, when backstop subassembly 24 is triggered by host computer 1, it is more reliable to trigger.

It will be appreciated by those skilled in the art that in some embodiments, the stop assembly 24 may be movably disposed on the main body 1, if the problem that the motor installation cavity of the processing cup assembly 2 may be filled with water and dust in the non-use state is not considered, and the problem that the air flow is not smooth due to the blockage of the main body 1 when the processing cup assembly 2 is installed on the main body 1 is only considered. Under this structure, the vent of processing cup subassembly 2 is normally open, utilizes processing cup subassembly 2 to realize the state switching to the backstop subassembly to the pressure of host computer 1, equally can make the air current wind channel with through the inside and outside intercommunication of host computer 1, ensures that the airflow of passing through motor element 22 is sufficient.

In some embodiments, the stopping assembly 24 is provided with a triggering member 241 capable of being pushed by the host 1, and the position change of the triggering member 241 can realize the state switching of the stopping assembly 24. Generally speaking, the processing cup assembly 2 is vertically installed on the main machine 1, when the processing cup assembly 2 is installed on the main machine 1, the main machine 1 can vertically push the trigger 241 upwards, and the state of the stop assembly 24 can be changed by the position change of the trigger 241, so as to realize the opening and closing of the airflow channel.

Some embodiments of this application set up trigger 241 and processing cup subassembly 2 trigger distance h and be greater than or equal to 0, when processing cup subassembly 2 places at the mesa promptly, trigger 241 is higher than the mesa, trigger 241 and mesa contactless (h > 0), or trigger 241 and mesa only have the contact and do not have effort (h ═ 0), when processing cup subassembly 2 independently places on smooth mesa, can not produce thrust to trigger 241, the air current wind channel is in the normally closed state, reduce the inside water and the dust that get into the motor installation cavity, motor element's life is improved.

As shown in fig. 3 and 5, in some embodiments, in order to ensure the triggering effect on the triggering member 241, the main body 1 is provided with the acting member 11 along the installation direction of the processing cup assembly 2, and the acting member 11 is arranged corresponding to the position of the stopping assembly 24. In some embodiments of the present application, the host 1 and the processing cup assembly 2 are vertically installed when being matched, when the processing cup assembly 2 is installed on the host 1, the processing cup assembly 2 moves downwards under the action of gravity, and because the action piece 11 corresponds to the position of the stopping assembly 24, the stopping assembly 24 receives the reaction force of the action piece 11, so that the state switching is realized, and the action piece 11 can ensure that the stopping assembly is triggered in place. Specifically, in some embodiments, the acting element 11 is a boss protruding from the upper surface of the main body 1, and the vent 23 is disposed on the lower surface of the processing cup assembly 2, and the boss is perpendicular to the upper surface of the main body 1. In combination with the foregoing embodiment, since the triggering distance is set between the triggering part 241 and the bottom of the processing cup assembly 2, in order to facilitate the setting, the ventilation opening 23 is recessed in the lower surface of the processing cup assembly 2, and a groove is formed in the lower surface of the processing cup assembly 2, and the groove is matched with the boss on the upper surface of the host 1, so that the positioning of the processing cup assembly 2 and the host 1 can be realized, and the switching of the state of the stopping assembly 24 can be realized.

As shown in fig. 8, in some embodiments, the host 1 is provided with an air inlet channel 12 corresponding to the acting element 11, and the air inlet channel 12 is communicated with the air flow passage. For example, the structure of the air inlet channel 11 may be combined with the boss structure disclosed in the foregoing embodiments, the main body 1 vertically extends upward from the bottom surface and protrudes from the top surface to form the boss structure, the boss is hollow, and both the upper and lower end surfaces are provided with through holes, so that the air inlet channel 12 is formed inside the boss. The through hole on the upper end surface of the boss corresponds to the position of the vent 23. This application can communicate to the air current wind channel at the inlet channel 12 that host computer 1 set up, and when motor element 22 during operation, the suction effect to the air current that produces can be with outside air suction motor installation cavity, and inlet channel 12 can play the guide effect to the air current. As shown in the figures, in some embodiments, the upper surface of the whole host 1 is provided with a sinking platform 13 (as shown in fig. 2) capable of partially or completely accommodating the processing cup assembly 2, the processing cup assembly 2 is accommodated inside the sinking platform 13 when being matched with the host 1 to form an enclosed structure, the structure has the problem that air flow can only enter the motor installation cavity from the circumferential gap between the host 1 and the processing cup assembly 2, the air flow is small, and the air inlet channel 12 arranged on the host 1 according to the structure can enable the air flow to still smoothly enter the motor installation cavity to effectively dissipate heat of the motor assembly 22, so that the service life of a product is ensured.

As shown in fig. 5, in one embodiment, the vent 23 is spaced from the bottom of the processing cup assembly 2 by a distance H of 10 mm. Through setting up the distance, when making processing cup subassembly 2 place on the mesa, vent 23 has certain height, and inside this height can prevent to wash the water in the basin from entering into the motor installation cavity from vent 23, avoids inside components and parts short circuit.

As can be understood by those skilled in the art, the distance H between the vent 23 and the bottom of the processing cup assembly 2 can ensure that the stop assembly 24 is effectively ventilated in the second state on the premise that H is more than or equal to 2mm and less than or equal to 20mm, and can prevent water from entering the motor mounting cavity from the bottom of the processing cup assembly 2, so that the use is more reliable. When the distance between the vent 23 and the bottom of the processing cup assembly 2 is less than 2mm, if water exists on the table top on which the processing cup assembly 2 is placed, the water cannot be separated from the vent 23, and the water is sucked into the motor installation cavity when the motor assembly 22 is started; when the distance between the vent 23 and the bottom of the processing cup assembly 2 is greater than 20mm, the acting element 11 required to be arranged on the main machine 1 is too high, which is not favorable for maintaining the structural strength of the acting element 11. And the processing cup assembly 2 may interfere with installation due to its excessive length when mated with the main body 1.

In some embodiments, the number of the vent holes 23 is 1, and correspondingly, the number of the acting elements 11 provided on the main body 1 is also 1. In order to improve the air intake of the motor installation cavity, a plurality of ventilation openings can be arranged. For example, as shown in fig. 6, 2 air vents are provided in the bottom of the processing cup unit 2, and the number of the operating members 11 provided in the main body 1 is 2. When two vents 23 are symmetrically arranged, the air flow entering the interior of the processing cup assembly 2 can form convection and is not beneficial to flowing into the motor installation cavity, therefore, in order to improve the circulation of the air flow, the 2 vents 23 are eccentrically arranged, and the air flow enters the motor installation cavity along the vents 23.

Those skilled in the art can understand that the number of the ventilation openings 23 can be more, and the ventilation openings 23 are eccentrically arranged, so that effective heat dissipation of the motor assembly 22 is realized, the problem of air flow convection generated by air intake of the ventilation openings 23 is reduced, and the heat dissipation effect is better.

As shown in fig. 6-8, in some embodiments of the present application, the stop assembly 24 includes a push plate 242 for blocking the air flow path and a reset member 243 acting on the push plate 242, wherein the reset member 243 can drive the push plate 242 to fit the vent 23. Specifically, in combination with the acting element 11 in the foregoing embodiment being a boss structure disposed on the upper surface of the main unit 1, one end of the push plate 242 passes through the vent 23 and abuts against the upper end surface of the boss, so as to form the triggering element 241 in the foregoing embodiment, and the other end is limited on the upper surface of the vent 23, and the push plate 242 is movable to form clearance fit with the through hole in the axial direction. The portion of the push plate 242 limited on the upper surface of the vent 23 is a plate-shaped structure and can cover the vent 23 to form a plug. The vent 23 is a grid-shaped structure, a guide post 244 is provided on the grid to guide the movement of the push plate 242, the reset member 243 is a spring sleeved on the guide post 244, the guide post 244 is provided with a threaded hole, a fastening screw 245 is screwed on the threaded hole, and two ends of the spring are respectively abutted against the fastening screw 245 and the push plate 242. When the processing cup assembly 2 is installed on the main machine 1, the reaction force generated by the main machine 1 on the stop assembly 24 acts on the reset member 243, so that the reset member 243 is in a compression state, the reset member 243 has a tendency of pushing the push plate 242 back to the ventilation opening 23 in the compression state, when the main machine 1 is separated from the processing cup assembly 2, the stop assembly 24 can be switched back to the first state from the second state, the reset member 243 pushes the push plate 242 to cover the ventilation opening 23, so that the airflow duct is closed, the reset member 243 and the push plate 242 are matched to realize switching of the ventilation opening 23 by a simpler thrust structure, the cost is low, and the reliability is high.

As shown in FIG. 3, in some embodiments, the motor assembly 22 is housed with a shroud 25 that forms an airflow path. Some food preparation machines have a heating element for preparing hot drinks, the heating element is usually arranged at the bottom of the processing cup assembly 2, the air guide sleeve 25 is covered outside the motor assembly 22 to separate the motor assembly 22 from the heating element, the heat generated when the processing cup assembly 2 is heated can be prevented from influencing the motor assembly 22 and other components, the air flow can be concentrated, the air flow velocity is improved, and the heat dissipation efficiency is improved.

Specifically, the air guide sleeve 25 comprises an upper sleeve body 251 and a lower sleeve body 252, the upper sleeve body 251 is fixed to the motor assembly 22, the lower sleeve body 252 is integrally formed with a base at the bottom of the processing cup assembly 2, the radial dimension of the lower sleeve body 252 is smaller than that of the upper sleeve body 251, so that a gap is formed between the upper sleeve body 251 and the lower sleeve body 252, and meanwhile, the upper sleeve body 251 and the lower sleeve body 252 are radially provided with overlapped sections to form a circuitous airflow channel. The airflow channel formed by the overlapped section between the upper cover body 251 and the lower cover body 252 can guide airflow to be led into the motor installation cavity in a circuitous shape, the airflow speed is higher, and the heat dissipation efficiency is higher. And because circuitous air current wind channel route is longer, more heat can be taken away after the outside air current flows in, and the radiating effect is more obvious.
