Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a lid assembly and a food processor. Background Technology

[0002] As people's living standards continue to improve, many different types of food processors have appeared on the market. Food processors can include machines that crush and blend food, such as soy milk makers, blenders, or high-speed blenders.

[0003] In related technologies, food processors need to be equipped with components to detect when the lid is open, in order to prevent safety hazards caused by the food processor operating with the lid open. However, the installation of such components increases the overall space occupied by the food processor, and can easily cause interference between structural parts and vibration issues during use. Utility Model Content

[0004] This application provides a lid assembly and a food processor that reduces the space occupied by the lid opening protection scheme.

[0005] A first aspect of this application provides a lid assembly for use in a food processor; the lid assembly includes a blender cup lid and a machine lid;

[0006] The mixing cup lid includes a lid body, a handle structure, and a magnetic component; the lid body includes an inner side, an outer side, and a vent hole connecting the inner side and the outer side, and the handle structure is disposed on the outer side; the handle structure includes a gripping body, the gripping body includes a first vertical surface facing the vent hole, and the magnetic component is disposed on the inner side of the first vertical surface;

[0007] The cover is equipped with a reed switch. When the cover is closed, the reed switch is conductive within the magnetic field range of the magnetic component; when the cover is open, the reed switch is disconnected outside the magnetic field range of the magnetic component. The first vertical surface of the handle structure facing the vent prevents the user from directly gripping the side of the handle near the vent, and provides sufficient space for the installation of the magnetic component on the inner side near the first vertical surface, avoiding any increase in the thickness of the handle structure due to the installation of the magnetic component.

[0008] Furthermore, the gripping body includes a second upright surface facing away from the vent, and the magnetic component is disposed on the inner side of the second upright surface. The second upright surface, located on the side facing away from the vent, further prevents the user from gripping the side facing the vent using the structure on the side facing away from the vent. It also creates sufficient space for the magnetic component to be installed on the inner side near the second upright surface, improving the flexibility of the magnetic component placement and optimizing the cover opening detection scheme.

[0009] Furthermore, the gripping body includes a gripping side, which connects the first vertical surface and the second vertical surface; the gripping side is provided with a gripping structure, which protrudes outward from the gripping body. The gripping structure is provided on the gripping side between the first and second vertical surfaces, making the handle structure easy to grip during use and preventing users from getting burned by gripping the side near the vent.

[0010] Furthermore, the gripping structure includes a raised structure that smoothly transitions with the gripping side. The smooth transition between the raised structure and the gripping side can improve the smoothness of the structure and the gripping feel.

[0011] Furthermore, the gripping structure is located at the top of the gripping side, and the space below the top gripping structure forms a gripping operation space, improving gripping comfort and convenience.

[0012] Furthermore, the handle structure also includes a handle cover; the gripping body is provided with a mounting groove, the magnetic component is assembled into the mounting groove, and the handle cover is assembled into the gripping body and covers the magnetic component. Placing the magnetic component in the handle structure provides sufficient mounting space for it, avoiding food corrosion and hygiene problems caused by insufficient space for the magnetic component in the cover body, which would require it to contact the inside of the mixing cup.

[0013] Furthermore, the magnetic component includes a first edge close to the first vertical surface, and the distance between the first edge and the first vertical surface is less than or equal to 3mm, so as to improve the induction effect between the magnetic component and the reed switch and reduce the interference of the handle structure on magnetic induction.

[0014] Furthermore, the outer surface includes a recessed portion facing the inner surface, and the handle structure is disposed in the recessed portion. By placing the handle structure within the recessed portion on the outer surface of the cup lid, the space occupied by the handle structure in terms of the cup lid's thickness is reduced.

[0015] Furthermore, the lid includes a housing, the inner surface of which forms an assembly cavity, and a first region of the housing protrudes into the assembly cavity such that the outer surface of the housing forms a clearance recess facing the mixing cup lid; when the lid is in a closed state, at least a portion of the handle structure is received in the clearance recess.

[0016] The assembly cavity includes a first assembly space and a second assembly space located on both sides of the first region, and the reed switch is disposed within the first assembly space and / or the second assembly space. The protrusion of the first region into the assembly cavity of the housing not only forms a clearance space for accommodating the handle structure on the outside of the housing, but also forms the first assembly space and the second assembly space located on both sides of the first region inside the housing. Placing the reed switch in the first assembly space and / or the second assembly space, and avoiding the recessed area for accommodating the handle structure, helps to reduce the overall thickness of the food processor.

[0017] According to a second aspect of this application, a food processor is provided, the food processor comprising: a base, a blending cup, and any of the lid components described in the first aspect;

[0018] The base includes a base and a support extending upward from the base;

[0019] The mixing cup is assembled to the base, and the mixing cup lid covers the mixing cup; the machine cover is assembled to the support base, and the machine cover includes a closed state covering the mixing cup assembly and an open state away from the closed state. The first vertical surface of the lid handle structure facing the vent prevents the user from directly gripping the handle side near the vent, and forms sufficient space for magnetic component installation on the inner side near the first vertical surface, avoiding the increase in the thickness of the handle structure due to magnetic component installation, which helps to reduce the overall height of the blender and optimize the blender structure.

[0033] With the continuous improvement of people's living standards, many different types of food processors have appeared on the market. Food processors can include machines that crush and blend food, such as soy milk makers, blenders, or high-speed blenders. In related technologies, food processors need to be equipped with components to detect when the lid is open, in order to prevent safety hazards caused by the food processor operating with the lid open. However, the inclusion of lid-opening detection components increases the overall space occupied by the food processor, and can easily cause interference between structural components and vibration problems during use.

[0034] This application provides a lid assembly for use in a food processor. Figure 1 This is a schematic cross-sectional view of a cover component according to an exemplary embodiment of this application. Figure 2 This is a schematic cross-sectional view of a cup lid according to an exemplary embodiment of this application. Figure 3 This is a three-dimensional structural diagram of a cup lid according to an exemplary embodiment of this application, as shown below. Figures 1-3 As shown, the lid assembly includes a mixing cup 21 lid 25 and a machine lid 30. The mixing cup 21 lid 25 includes a lid body 251, a handle structure 252, and a magnetic element 26. The lid body 251 includes an inner side 2511, an outer side 2512, and a vent 2513 connecting the inner side 2511 and the outer side 2512. The handle structure 252 is disposed on the outer side 2512. The handle structure 252 includes a gripping body 2521, which includes a first vertical surface 2521a facing the vent 2513. The magnetic element 26 is disposed on the inner side of the first vertical surface 2521a. The machine lid 30 is provided with a reed switch 32. When the machine lid 30 is in the closed state, the reed switch 32 is conductive within the magnetic field range of the magnetic element 26. When the machine lid 30 is in the open state, the reed switch 32 is disconnected outside the magnetic field range of the magnetic element 26.

[0035] The first vertical surface 2521a of the handle structure 252 facing the vent 2513 can prevent the user from directly gripping the handle side near the vent 2513, and sufficient space for the installation of the magnetic component 26 is formed on the inner side near the first vertical surface 2521a to avoid the installation of the magnetic component 26 causing an increase in the thickness of the handle structure 252.

[0036] It should be noted that the aforementioned magnetic component 26 can be a magnet.

[0037] In some embodiments, the gripping body 2521 may include a second vertical surface 2521b facing away from the vent 2513, and a magnetic element 26 is provided on the inner side of the second vertical surface 2521b. The second vertical surface 2521b is provided on the side facing away from the vent 2513, further preventing the user from gripping the side facing the vent 2513 using the structure on the side facing away from the vent 2513. It also provides sufficient mounting space for the magnetic element 26 near the inner side of the second vertical surface 2521b, which helps improve the flexibility of the magnetic element 26 installation and optimizes the cover opening detection scheme.

[0038] Furthermore, the gripping body 2521 may include a gripping side 2521c, which connects to the first vertical surface 2521a and the second vertical surface 2521b. The gripping side 2521c is provided with a gripping structure that protrudes outward from the gripping body 2521. The gripping structure on the gripping side 2521c between the first vertical surface 2521a and the second vertical surface 2521b facilitates gripping of the handle structure 252 during use, preventing users from being burned by gripping the side near the vent 2513.

[0039] The gripping structure includes a raised structure that smoothly transitions with the gripping side 2521c. This smooth transition between the raised structure and the gripping side 2521c enhances the structural fluidity and grip feel. Alternatively, the gripping structure can also be a raised structure that transitions with a sharp angle to the gripping side 2521c, depending on the specific design requirements of the cup lid 25.

[0040] Furthermore, the gripping structure can be located on the top of the gripping side 2521c, utilizing the space below the top gripping structure to form a gripping operation space, thereby improving gripping comfort and convenience.

[0041] In some embodiments, the handle structure 252 may further include a handle cover 2522, the gripping body 2521 is provided with a mounting groove 2523, the magnetic component 26 is assembled into the mounting groove 2523, and the handle cover 2522 is assembled into the gripping body 2521 and covers the magnetic component 26. Placing the magnetic component 26 in the handle structure 252 provides sufficient mounting space for the magnetic component 26, avoiding food corrosion and hygiene problems caused by insufficient space for the magnetic component 26 to contact the inside of the mixing cup 21 if it were placed in the cover body 251.

[0042] The depth of the mounting groove 2523 can be greater than or equal to the thickness of the magnetic component 26 to completely accommodate the magnetic component 26 and avoid the magnetic component 26 occupying space on the thickness of the cup lid 25.

[0043] In some embodiments, the magnetic element 26 includes a first edge close to the first vertical surface 2521a, and the distance L1 between the first edge and the first vertical surface 2521a is less than or equal to 3 mm, so as to improve the induction effect between the magnetic element 26 and the reed switch 32 and reduce the interference of the handle structure 252 on the magnetic induction.

[0044] In some embodiments, when the cover 30 is in the closed state, the distance L2 between the magnetic element 26 and the reed switch 32 is less than or equal to 8 mm, so as to improve the sensing effect between the magnetic element 26 and the reed switch 32.

[0045] In some embodiments, the lid 30 is movably mounted on the support base 12, and the lid 30 has an open state and a closed state relative to the mixing cup assembly 20. The lid 30 may be provided with at least two reed switches 32, and the cup lid 25 is provided with a magnetic element 26. When the lid 30 is closed on the mixing cup 21, the reed switches 32 are closed under the magnetic force of the magnetic element 26, and the control plate 31 can only be opened at this time. When the lid 30 is open, the reed switches 32 are disengaged because they are away from the magnetic element 26, and the control plate 31 cannot be opened at this time. In this way, the control plate 31 is prevented from opening when the lid 30 is not fully closed, making it safer to use. With at least two reed switches 32 provided on the lid 30, when one reed switch 32 fails, the other reed switches 32 can still work, improving the reliability of the food processor 100's lid opening protection function.

[0046] For example, the lid 30 may include a housing 33, the inner surface of which forms an assembly cavity. A first region 331 of the housing 33 protrudes into the assembly cavity, such that the outer surface of the housing 33 forms a clearance recess 334 facing the cup lid 25 of the mixing cup 21. When the lid 30 is in the closed state, at least a portion of the handle structure 252 is received in the clearance recess 334. The assembly cavity includes a first assembly space 332 and a second assembly space 333 located on both sides of the first region 331, and a reed switch 32 is provided in the first assembly space 332 and / or the second assembly space 333. The first region 331 protrudes into the assembly cavity of the housing 33, forming not only a clearance space for the handle structure 252 on the outside of the housing 33, but also a first assembly space 332 and a second assembly space 333 located on both sides of the first region 331 inside the housing 33. By placing the reed switch 32 in the first assembly space 332 and / or the second assembly space 333, and clearing the recess 334 to accommodate the handle structure 252, it helps to reduce the overall thickness of the food processor 100.

[0047] The aforementioned first assembly space 332 can be located close to the power board 13. Reed switches 32 are respectively installed in the first assembly space 332 and the second assembly space 333. The reed switches 32 located in the first assembly space 332 are electrically connected to the power board 13, and the reed switches 32 located in the second assembly space 333 are electrically connected to the control board 31. This optimizes the circuit layout and improves the convenience of the reed switch 32's conductive connection. Furthermore, depending on specific structural requirements, the reed switches 32 can be electrically connected to either the control board 31 or the power board 13, enhancing the flexibility of the reed switch 32's circuit connection.

[0048] Furthermore, when the cover 30 is in the closed state, at least a portion of the magnetic element 26 and the reed switch 32 overlap in the height direction of the cover 30, which helps to reduce the distance between the magnetic element 26 and the reed switch 32 and improve the sensing effect of the magnetic element 26 and the reed switch 32.

[0049] In some embodiments, the outer surface 2512 may include a recess that is recessed toward the inner surface 2511, and a handle structure 252 is disposed in the recess. By disposing the handle structure 252 in the recess of the outer surface 2512 of the cup lid 25, the space occupied by the handle structure 252 in terms of the thickness of the cup lid 25 is reduced.

[0050] This application further provides a food processor 100, such as Figures 4-6 As shown, the food processor 100 includes a base 10, a blending cup 21, and the aforementioned lid assembly. The base 10 includes a base 11 and a support 12 extending upward from the base 11. The blending cup 21 is assembled to the base 11, and a lid 25 covers the blending cup 21. The lid 30 is assembled to the support 12, and the lid 30 includes a closed state covering the blending cup assembly 20 and an open state deviating from the closed state.

[0051] The first vertical surface 2521a of the cup lid 25 handle structure 252 of the above-mentioned lid assembly facing the vent 2513 can prevent the user from directly gripping the handle side near the vent 2513. Moreover, sufficient space for the installation of the magnetic component 26 is formed on the inner side near the first vertical surface 2521a, so as to avoid the installation of the magnetic component 26 causing an increase in the thickness of the handle structure 252. This helps to reduce the overall height of the food processor 100 and optimize the structure of the food processor 100.

[0052] Please see Figures 4-6 The food processor 100 can be used to make soy milk, rice paste, juice, etc. The food processor 100 includes a base 10, a blending cup assembly 20, and a lid 30.

[0053] The base 10 includes a base 11 and a support 12 extending upward from the base 11. The support 12 and the base 11 can be integrally formed, or they can be formed separately and then assembled together.

[0054] The mixing cup assembly 20 is assembled on the base 11. The mixing cup assembly 20 includes a mixing cup 21, a heating plate 22 disposed at the bottom of the mixing cup 21, and a blade assembly 23. The mixing cup 21 is used to hold food, the heating plate 22 is used to heat the food in the mixing cup 21, and the blade assembly 23 is used to stir and grind the food in the mixing cup 21.

[0055] The lid 30 is assembled to the support base 12 and covers the mixing cup assembly 20. The lid 30 is rotatably assembled to the support base 12. In another embodiment, the lid 30 is rotatably assembled to the support base 12 in a horizontal direction. In yet another embodiment, the lid 30 is detachably assembled to the support base 12.

[0056] The support base 12 houses a power board 13, and the cover 30 houses a control board 31 electrically connected to the power board 13. A motor 40 is located within the base 11 or at the bottom of the mixing cup 21. The motor 40 includes an output shaft 41, and the blade assembly 23 is located at the top of the output shaft 41. In one embodiment, the motor 40 is a brushless motor without a rear end cover, resulting in a lower overall height for the motor 40, which helps reduce the overall height of the food processor 100. In other embodiments, the motor 40 can also be a conventional brushed motor or a brushless motor.

[0057] Since the power board 13 is located inside the support base 12 and the control board 31 is located inside the cover 30, the power board 13, control board 31 and motor 40 are not stacked together. By reasonably arranging the positions of the three, the height of the food processor 100 can be effectively reduced, so that the overall height of the food processor 100 is no more than 280 mm, making it more compact and exquisite. In this way, the vibration generated by the food processor 100 during operation can be reduced, and it occupies less space.

[0058] In another embodiment, the power board 13 and control board 31 are both disposed within the cover 30, and the motor 40 is disposed within the base 11 or at the bottom of the mixing cup 21, which also reduces the height of the food processor 100. In yet another embodiment, the power board 13 and control board 31 are both disposed within the cover 30, and the motor 40 is disposed within the cup lid 25 of the mixing cup assembly 20. In yet another embodiment, the power board 13 is disposed within the support base 12, the control board 31 is disposed within the cover 30, and the motor 40 is disposed within the cup lid 25 of the mixing cup assembly 20.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
