Technical Field

[0001] This utility model relates to the field of food processor technology, and in particular to a noise-reducing food processor. Background Technology

[0002] A food processor is a small kitchen appliance used to process various ingredients. It can perform multiple operations such as chopping, stirring, mixing, juicing, and grinding, including soy milk makers, blenders, and high-speed blenders.

[0003] Because food processors typically rely on a motor to drive the blades to rotate at high speed and pulverize food, they generate considerable noise during operation, which severely impacts the user experience. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a noise-reducing food processor, which is covered by a soundproof cover outside the base and surrounds the outer periphery of the processing cavity, so as to isolate the transmission of vibration inside the processing cavity and reduce the generation of noise.

[0006] A noise-reducing food processor, comprising:

[0007] The machine base is provided with a machining cavity and a locking part;

[0008] A stirring assembly, comprising a stirring element and a driving element, wherein the stirring element is rotatably disposed in the processing chamber, and the driving element is used to drive the stirring element to rotate;

[0009] A soundproof cover is detachably mounted on the machine base and is used to surround the outer periphery of the processing cavity after being mounted on the machine base; the locking part is used to lock the soundproof cover in a locking engagement after the soundproof cover is mounted on the machine base to lock the soundproof cover.

[0010] Furthermore, the base is provided with a limiting step, which extends circumferentially along the base and forms the locking part; the limiting step is used to abut against the inner wall of the soundproof cover after the soundproof cover is placed on the base.

[0011] Furthermore, the limiting step is provided with a first guide surface, which slides in cooperation with the outer periphery of the soundproof cover to guide the soundproof cover to cover the outer periphery of the limiting step and to fit tightly with the outer periphery of the limiting step; the first guide surface is an arc surface.

[0012] Furthermore, the outer periphery of the base is provided with a first magnetic attraction member, and the soundproof cover is provided with a second magnetic attraction member. The first magnetic attraction member and the second magnetic attraction member magnetically engage to lock the soundproof cover.

[0013] Furthermore, the base is also equipped with a Hall switch, which is used to send a signal after the first magnetic attractor and the second magnetic attractor are magnetically attracted together.

[0014] Furthermore, the soundproof cover is made of a transparent material.

[0015] Furthermore, the machine base is also provided with a processing cup, and the processing cavity is formed inside the processing cup; the processing cup has an opening, and the opening communicates with the processing cavity.

[0016] Furthermore, the top of the base is provided with a cover plate, which covers the opening.

[0017] Furthermore, it also includes a handle, and the outer periphery of the base is provided with a connecting protrusion, the handle being connected to the connecting protrusion; the soundproof cover is provided with a connecting notch, and the connecting protrusion is used to engage with the connecting notch after the soundproof cover is placed over the base.

[0018] Furthermore, two second guide surfaces are provided on both sides of the connecting notch, and a third guide surface is provided on the top of the connecting protrusion.

[0019] In summary, the noise-reducing food processor provided by this utility model has the following technical effects: In specific use, a soundproof cover can be placed around the outer periphery of the machine base and locked by the locking part on the machine base, so that the soundproof cover can be stably placed around the outside of the processing cavity. In this way, the processing cavity can be isolated from the outside world by the soundproof cover, indirectly cutting off the channel for sound to propagate from the processing cavity to the outside world. When the stirring component vibrates at high speed under the drive of the driving component, the presence of the soundproof cover can effectively reduce the propagation of this vibration and reduce the generation of noise.

[0026] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] See Figures 1 to 4 This utility model discloses a noise-reducing food processor, including a base 10, a stirring assembly 50, and a soundproof cover 20. The base 10 is provided with a processing cavity 31 and a locking part. The stirring assembly 50 includes a stirring element and a driving element. The stirring element is rotatably disposed in the processing cavity 31. The driving element is used to drive the stirring element to rotate. The soundproof cover 20 is detachably disposed on the base 10 and surrounds the outer periphery of the processing cavity 31 after being disposed on the base 10. The locking part locks with the soundproof cover 20 after it is disposed on the base 10 to lock the soundproof cover 20.

[0030] Based on the above structure, during assembly, the stirring component is installed in the processing chamber 31, and the driving component can be set in the part of the base 10 away from the processing chamber 31 and connected to the stirring component to drive the stirring component to rotate, so as to realize the processing operation of the food in the processing chamber 31 by rotating the stirring component.

[0031] When the mixing components are ready to operate, the soundproof cover 20 is placed on the outer periphery of the base 10 and locked by the locking part on the base 10, so that the soundproof cover 20 will not fall off accidentally when the mixing components are running at high speed, which increases the overall stability of the food processor to a certain extent.

[0032] Since vibrations may occur when the mixing components are running at high speed, excessive vibrations may affect the normal operation of the food processor or even cause it to shift. The soundproof cover 20, through its tight connection with the base 10, can play a certain stabilizing role, reduce the shaking of the food processor, further reduce the probability of noise caused by shaking, and reduce noise generation.

[0033] More specifically, since various noises are generated when the mixing components start working, the soundproof cover 20 is placed around the base 10 and locked to isolate the mixing components of the food processor from the outside world, cutting off the channel for sound to travel from the mixing components to the outside world. When the mixing components vibrate at high speed under the drive of the drive component, the sound must penetrate the soundproof cover 20 to travel out. At this time, the soundproof cover 20 acts like a sealed wall, blocking the sound inside the processing chamber 31. This reduces the sound of vibrations generated by the mixing components or drive component during operation and reduces noise.

[0034] It should be noted that the soundproof cover 20 in this embodiment can be made of existing materials such as PC plastic, polyester fiber sound-absorbing board, steel plate or ABS plastic, which have a certain sound-blocking effect. During assembly, a locking part can be formed by setting a buckle or a block on the base 10, and a corresponding slot or slot structure matching the locking part can be set on the soundproof cover 20. When the soundproof cover 20 is placed on the outer periphery of the base 10, locking is achieved by inserting the buckle into the slot and tightening it.

[0035] Of course, the locking part can also be a limit block or an elastic block or other structure set on the base 10. Specifically, when the locking part is a limit block, after the soundproof cover 20 is covered on the base 10, the inside of the soundproof cover 20 abuts against the outer periphery of the limit block. At this time, when the inner wall of the soundproof cover 20 abuts against the outer periphery of the limit block, friction will be generated, which plays a positioning role. When the stirring component vibrates at high speed on the base 10, this friction can prevent the soundproof cover 20 from moving, thereby preventing the soundproof cover 20 from being displaced on the base 10 and realizing the locking of the soundproof cover 20.

[0036] When the locking part is an elastic block, the soundproof cover 20 abuts against the elastic block after being installed on the base 10. At this time, the elastic block will deform when it is squeezed by the soundproof cover 20, generating a reaction force. This reaction force will make the soundproof cover 20 fit more tightly on the base 10. For example, when the soundproof cover 20 is subjected to a slight external impact or the position of the soundproof cover 20 changes due to a small deformation of the internal structure of the equipment, the elastic deformation of the elastic block can be adjusted adaptively to always maintain the pressure on the soundproof cover 20, thereby maintaining sufficient friction to lock the soundproof cover 20. Moreover, the elastic block can make up for any small gaps that may exist between the base 10 and the soundproof cover 20, further improving the stability and sealing of the soundproof cover 20 and enhancing the sound insulation effect.

[0037] Furthermore, a limiting step 11 is provided on the base 10. During assembly, the limiting step 11 extends along the circumference of the base 10 and forms a locking part. After the soundproof cover 20 is placed over the base 10, the limiting step 11 abuts against the inner wall of the soundproof cover 20.

[0038] Specifically, in this embodiment, the locking part is formed by a limiting step 11 provided on the base 10. Since the limiting step 11 extends circumferentially along the base 10, when the inner wall of the soundproof cover 20 abuts against the limiting step 11, compared with simple point contact or small area contact, this circumferentially extended limiting step 11 structure greatly increases the contact area between the soundproof cover 20 and the base 10, making the connection between the soundproof cover 20 and the base 10 more stable, reducing the risk of sound leakage due to loosening of the soundproof cover 20 during equipment operation, and further improving the noise reduction effect.

[0039] It should be noted that the limiting step 11 in this embodiment can be integrally formed on the machine base 10 away from the processing cavity 31, so that the soundproof cover 20 can be placed on the periphery of the processing cavity 31 to achieve sound insulation.

[0040] Furthermore, the limiting step 11 is provided with a first guide surface 111, which slides with the outer periphery of the soundproof cover 20 to guide the soundproof cover 20 to cover the outer periphery of the limiting step 11 and to fit tightly with the outer periphery of the limiting step 11. The first guide surface 111 is an arc surface.

[0041] Specifically, when the soundproof cover 20 is placed on the outer periphery of the limiting step 11 of the base 10, the arc design of the first guide surface 111 can provide a smooth transition. The arc can guide the soundproof cover 20 to gradually fit with the limiting step 11 along its contour, making it easier for the soundproof cover 20 to be aligned and fitted into the outer periphery of the limiting step 11 during installation, and to abut against it. This reduces the resistance during installation and the possible jamming, greatly improving the convenience of installation.

[0042] In addition, when it is necessary to remove the soundproof cover 20, the user can apply external force to the soundproof cover 20 and pull it in the opposite direction to the limiting step 11. At this time, the arc design of the first guide surface 111 can provide a smooth transition, reduce resistance, make the process of removing the soundproof cover 20 smoother, and make it easier to separate the soundproof cover 20 from the base 10.

[0043] Of course, the same effect can be achieved when the first guide surface 111 is designed as an inclined surface.

[0044] More specifically, to make the connection between the soundproof cover 20 and the base 10 more stable, a first magnetic attraction component is provided on the outer periphery of the base 10, and a second magnetic attraction component is provided on the soundproof cover 20. During assembly, when the soundproof cover 20 abuts against the limiting step 11 and is initially locked, the first magnetic attraction component on the outer periphery of the base 10 and the second magnetic attraction component on the soundproof cover 20 will automatically attract each other, so that the soundproof cover 20 and the base 10 are locked again. In this way, the soundproof cover 20 and the base 10 can be doubly locked, making the soundproof cover 20 more stable after installation and less prone to loosening. This indirectly reduces the probability of the soundproof cover 20 shaking and generating noise due to vibrations caused by the stirring component or the driving component, thus reducing the probability of noise generation.

[0045] In addition, since the magnetic attraction uses magnetic force to attach the soundproof cover 20 to the base 10, when it is necessary to remove the soundproof cover 20, it is only necessary to apply a pulling force opposite to the direction of the magnetic force, and then smoothly pull the soundproof cover 20 outward until the first magnetic attraction component separates from the second magnetic attraction component.

[0046] It should be noted that the first magnetic component and the second magnetic component can be permanent magnets, electromagnets or magnetic sheets that magnetically attract each other. During assembly, the first magnetic component can be attached or glued to the outer periphery of the base 10, while the second magnetic component can be set on the soundproof cover 20 at the position corresponding to the first magnetic component, so that the two magnetically attract each other when they are assembled.

[0047] Furthermore, a Hall switch is also provided inside the base 10. The Hall switch sends a signal after the first magnetic attractor and the second magnetic attractor are magnetically engaged.

[0048] Specifically, since a Hall switch is installed inside the base 10, a magnetic field is generated when the first and second magnetic components are magnetically engaged. The change in this magnetic field is detected by the Hall switch. Since the Hall switch has a sensing element and a signal processing circuit inside, when the change in the magnetic field is detected, the sensing element generates a Hall voltage. This weak voltage signal is processed to form a trigger signal, which is then sent to the drive component or the controller inside the base 10 to indicate that the soundproof cover 20 has been installed through magnetic engagement and the stirring component can be started.

[0049] Furthermore, the soundproof cover 20 is made of transparent material.

[0050] Specifically, when the food processor is working, the display or screen on the base 10 will show important information such as mixing time, speed, and temperature (if there is a heating function). The transparent soundproof cover 20 allows users to easily view this information without opening the cover, so that users can observe the mixing and check the remaining time at the same time, thereby better grasping the progress of food preparation and improving the ease of use of the equipment and the user experience.

[0051] Furthermore, the base 10 is also provided with a processing cup 30, and a processing cavity 31 is formed in the processing cup 30. The processing cup 30 has an opening 32, which is connected to the processing cavity 31 so that the food can be introduced into the processing cavity 31 through the opening 32.

[0052] Specifically, during assembly, the processing cup 30 is placed inside the base 10, so that the shell of the base 10 surrounds the processing cup 30, and then the soundproof cover 20 is placed outside the base 10. In this way, the processing cavity 31 set inside the processing cup 30 can be surrounded by the base 10 and the soundproof cover 20, so that the noise generated when the stirring part is processed inside the processing cavity 31 can be blocked layer by layer, reducing the probability of noise being transmitted to the outside and improving the noise reduction effect.

[0053] It should be noted that the processing cup 30 can be connected to the machine base 10 in a detachable manner. For example, it can be connected to the machine base 10 by means of a snap-fit ​​or hook, or the processing cup 30 can be connected to the machine base 10 by a thread so that the two can be detached. In this way, the processing cup 30 can be removed at any time when it needs to be cleaned after long-term use, which is convenient for cleaning.

[0054] More specifically, a cover plate 13 is provided on the top of the base 10. When in use, after the user puts the food into the processing chamber 31 through the opening 32, the cover plate 13 can be used to seal the opening 32, so that the inside of the processing chamber 31 forms a sealed cavity, preventing external dust or impurities from entering the processing chamber 31 and contaminating the food. It can also reduce the risk of food splashing to the outside during processing. At the same time, it can also block the probability of noise from being transmitted from the opening 32 during processing, further reducing noise.

[0055] Furthermore, it also includes a handle 40, and a connecting protrusion 12 is provided on the outer periphery of the base 10. The handle 40 is connected to the connecting protrusion 12. The soundproof cover 20 is provided with a connecting notch 21. The connecting protrusion 12 is used to engage with the connecting notch 21 after the soundproof cover 20 is placed over the base 10.

[0056] Specifically, after the food processing is complete, the user can hold the handle 40 to lift the base 10 and then pour out the food from the processing chamber 31, making the operation more convenient.

[0057] In addition, to prevent the soundproof cover 20 from affecting the installation of the handle 40 after it is installed on the base 10, this embodiment uses a connecting protrusion 12 on the outer periphery of the base 10 to install the handle 40, and a connecting notch 21 on the soundproof cover 20. After the handle 40 is installed, the soundproof cover 20 can still be engaged with the connecting protrusion 12 through the connecting notch 21, so as to achieve a tight connection with the base 10. This further enhances the stability of the entire equipment structure and indirectly reduces the additional vibration and noise caused by the loosening or shaking of the soundproof cover 20, resulting in better noise reduction.

[0058] Furthermore, two second guide surfaces 22 are provided on both sides of the connecting notch 21, and a third guide surface 121 is provided on the top of the connecting protrusion 12. The second guide surfaces 22 and the third guide surfaces 121 are slidably engaged to guide the connecting protrusion 12 to be engaged into the connecting notch 21.

[0059] Specifically, both the second guide surface 22 and the third guide surface 121 can be set as arc surfaces. In this way, when the soundproof cover 20 slowly moves closer to the base 10, the arc surface design of the second guide surface 22 and the third guide surface 121 can provide a smooth transition. The soundproof cover 20 is guided to gradually match the contour of the connecting protrusion 12 and snap into the outer periphery of the connecting protrusion 12 until it is completely locked. This reduces the resistance during installation and the possible jamming phenomenon, and greatly improves the convenience of installation.

[0060] Of course, the same effect can be achieved when the second guide surface 22 and the third guide surface 121 are designed as inclined surfaces.

[0061] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
