Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a food processing machine. Background Art

[0002] Patent number CN220442544U discloses a food processor with excellent noise reduction. The processor comprises a cup, a cup lid, a motor, a housing containing the cup and motor, and a base connected to the bottom end of the housing. A rotating shaft driven by the motor extends through the bottom wall of the cup and into the cup. A crushing device is provided at the end of the rotating shaft. The cup lid includes a cover portion that is mounted on the outside of the housing. The base is integrally formed with a mating portion, and the bottom end of the cover portion cooperates with the mating portion to achieve a seal. This solution not only protects the cover portion from vibration during operation of the food processor, but also seals the bottom end of the cover portion, achieving noise reduction.

[0003] However, in the prior art, in order to achieve sealing between the mating portion and the cover portion, a step is usually provided on the base, and a sealing ring is sleeved on the outer periphery of the step, and the soundproof cover is supported on the sealing ring. Referring to the mixer disclosed in CN219397043U, the soundproof cover is plugged into and fitted with the step portion through the open mouth, and the open mouth and the step portion clamp the second sealing ring.

[0004] However, for the above-mentioned traditional food processing machine in which the motor and the cup body are fixed as one, the base generally includes a base shell and a heating plate bracket. The heating plate bracket supports the heating plate and is sleeved on the lower part of the cup body, so that the heating plate closes the bottom opening of the cup body. The base shell is sleeved on the outer periphery of the heating plate bracket to enclose the motor. Therefore, an annular fitting gap is generated between the heating plate bracket and the cup body. Since the user needs to tilt the cup body to pour the slurry, the slurry may enter the heating plate bracket through the fitting gap during the pouring process. There is a sealing ring between the heating plate bracket and the heating plate, making it difficult for water that enters the heating plate bracket to be discharged, which is easy to breed bacteria and produce odor. It may also enter the processing chamber, which is easy to cause food safety problems. Utility Model Content

[0005] The utility model provides a food processing machine, which integrates the sealing between the fixing seat and the cup body and the isolation and noise reduction function of the sound insulation cover through a sealing ring, thereby solving the problem that water entering the fixing seat causes odor, and the food processing machine needs to seal and isolate multiple positions separately, resulting in a complex and independent structure and complicated installation process.

[0006] The technical solution adopted by the present invention is as follows: the present invention provides a food processing machine, comprising a cup body with a built-in crushing knife, a heating plate encapsulated at the bottom of the cup body, a fixing seat supporting the heating plate and sleeved and fixed on the lower part of the cup body, and a shell sleeved on the outside of the fixing seat and connected to the fixing seat, a motor is provided in the shell, a rotating shaft driven by the motor passes through the heating plate and is connected to the crushing knife, an annular installation gap is formed between the fixing seat and the cup body, a sealing ring is provided at the installation gap, the food processing machine also includes a sound insulation cover buckled on the outside of the cup body, a supporting surface for supporting the sound insulation cover is provided on the top of the shell, the sealing ring is provided with an extension portion extending to the supporting surface, and the sound insulation cover is pressed against the extension portion.

[0007] The present invention provides a food processor, wherein a fixing base is provided, the fixing base supports a heating plate and is sleeved and fixed to the lower portion of a cup body, thereby achieving a reliable structural assembly to enclose a processing chamber for processing food. An annular installation gap is formed between the fixing base and the cup body, and a sealing ring is provided in the installation gap to seal the installation gap between the fixing base and the cup body, thereby preventing water from entering the fixing base during pouring, overflowing, and cleaning, thereby generating odor and breeding bacteria. The food processor is hygienic and food-safe. The sealing ring is provided with an extension portion extending onto the support surface, and the sound insulation cover presses against the extension portion. Therefore, the sound insulation cover forms a flexible contact with the support surface of the housing through the extension portion. During operation of the motor, vibration generated by the motor is transmitted to the housing. The vibration of the housing is absorbed by the extension portion as it continues to be transmitted outward, thereby preventing resonance noise from the sound insulation cover, thereby eliminating resonance noise at the source and achieving noise reduction. In addition, because the extension portion can be fixed in the installation gap by the sealing ring to form a limit, the extension portion is firmly positioned, reducing the risk of falling off, and achieving effective and long-term isolation between the sound insulation cover and the housing, and achieving a reliable structure. Therefore, the sealing ring integrates the dual functions of sealing and isolating resonance noise, and does not require the provision of multiple independent components to achieve this, making the overall structure simple and the installation process easy.

[0008] In a preferred embodiment, the cup body includes a main body section, an inwardly contracted transition section and a contraction section connected in sequence, the sealing ring is sleeved on the transition section, and the fixing seat is sleeved and fixed on the outer periphery of the contraction section to press the sealing ring onto the transition section to seal the installation gap.

[0009] The cup body is equipped with an inwardly contracting transition section and a contracting section, and the fixed seat is sleeved on the outer periphery of the contracting section, reducing the radial dimension of the entire device, which helps to reduce the overall volume and facilitate handling and storage. By sleeve-fitting the sealing ring into the transition section, and then pressing the sealing ring against the transition section after the fixed seat is in place, the sealing ring is clamped, thus strengthening the reliable connection between the sealing ring and the installation gap. Furthermore, the extension can be reliably limited by the clamping of the sealing ring, thereby reducing the risk of falling off, achieving a reliable isolation effect, and effectively reducing the noise of the entire device.

[0010] In a preferred embodiment, the top of the fixing seat is exposed from the shell, a fitting gap is formed at the fitting position between the fixing seat and the top of the shell, and the extension portion extends along the top surface of the fixing seat and covers the fitting gap.

[0011] The top of the mounting base is installed outside the housing, while the extension extends along the mounting base surface to cover the mating seam. Thus, the sealing ring not only seals the installation gap and the mating seam, but also insulates the soundproofing enclosure. This single component integrates multiple functions, reducing the number of parts and simplifying the installation process. Furthermore, the sealed mating seam prevents water from entering the housing and damaging the motor, extending the life of the food processor.

[0012] In a preferred embodiment, the top of the shell is provided with a baffle wall extending laterally toward the side wall of the cup body, the baffle wall covers the top of the fixing seat to hide the fixing seat in the shell, the sealing ring includes a first sealing portion clamped by the fixing seat and the cup body and a second sealing portion clamped by the baffle wall and the cup body, and the extension portion covers the outer surface of the baffle wall.

[0013] By providing a retaining wall on the top of the housing, the retaining wall covers the fixing base, concealing it within the housing. This avoids an exposed gap between the housing and the fixing base, thereby reducing the risk of water intrusion into the housing. The sealing ring includes a first sealing portion clamped between the fixing base and the cup body, and a second sealing portion clamped between the retaining wall and the cup body, thereby improving the sealing effect. At the same time, flexible contact is formed between the cup body and the fixing base, and between the retaining wall and the cup body, and each can be sealed by a single seal. The sealing ring also isolates the soundproof cover, reducing the number of parts in the entire device, simplifying the structure, and facilitating assembly. Furthermore, the extension portion is more reliably positioned on the support surface, achieving an isolation effect.

[0014] More preferably, the retaining wall is overlapped on the top of the fixing seat, and the sealing ring further includes a third isolation portion isolating between the retaining wall and the fixing seat.

[0015] By providing the third isolation portion, the first sealing portion and the second sealing portion are combined with each other to achieve that one seal can be sealed at multiple positions, thereby enhancing the sealing effect. At the same time, the third isolation portion has the effect of isolating the resonance between the fixed seat and the retaining wall, thereby reducing the working noise of the entire machine. In addition, the extension portion is more reliably positioned on the supporting surface, thereby achieving an isolation effect.

[0016] In a preferred embodiment, the shell is provided with a limiting wall extending upward from the supporting surface, the extending portion includes a first isolation portion extending laterally on the supporting surface and a second isolation portion extending vertically along the limiting wall, and the soundproof cover is abutted against the limiting wall through the second isolation portion.

[0017] By arranging a limiting wall extending upward from the supporting surface on the outer shell, radial limitation of the sound insulation cover is achieved. The extension part includes a first isolation part and a second isolation part. The first isolation part is located on the supporting surface and extends laterally, which can support the sound insulation cover to achieve axial isolation and limitation between the sound insulation cover and the outer shell. The second isolation part extends vertically along the limiting wall, and the sound insulation cover is abutted against the limiting wall through the second isolation part, so that the sound insulation cover and the limiting wall achieve radial isolation and limitation, further reducing resonance noise, improving noise reduction effect, and improving the installation stability of the sound insulation cover.

[0018] More preferably, an annular step is provided on the top of the housing, the limiting wall is a step side wall of the annular step, and the supporting surface is a step surface of the annular step;

[0019] Alternatively, an annular limiting groove is provided on the top of the shell, the open end of the sound insulation cover is inserted into the limiting groove, the limiting wall is the groove wall of the limiting groove, and the supporting surface is the groove bottom wall of the limiting groove.

[0020] Whether the limiting wall and support surface are formed by an annular step or by a limiting groove, both axial and radial isolation and limiting are achieved between the sound enclosure and the housing, ensuring stable installation and reducing overall operating noise. The annular step facilitates cleaning of accumulated dust on the support surface. The limiting groove provides more comprehensive and reliable radial limiting of the sound enclosure.

[0021] In a preferred embodiment, an annular positioning groove for mounting the extension portion is provided on the support surface, the lower end of the extension portion is sunk into the annular positioning groove, and the upper end of the extension portion protrudes from the annular positioning groove.

[0022] By providing an annular positioning groove on the supporting surface, the lower end of the extension part is sunk into the annular positioning groove, so that the extension part is fixed at the first level by means of the sealing ring clamping, and the annular positioning groove is used to achieve the second level of limitation, further preventing the extension part from moving or loosening, so that the isolation between the sound insulation cover and the outer shell is effective, and the noise reduction effect is achieved. In addition, the upper end of the extension part protrudes from the annular positioning groove to further ensure that the sound insulation cover is supported on the extension part to avoid contact with the outer shell, reduce resonance, and reduce noise.

[0023] In a preferred embodiment, an annular slot is provided on the upper surface of the extension portion, and the open end of the sound insulation cover is inserted into the slot.

[0024] By providing an annular slot on the upper surface of the extension, the open end of the soundproof cover is inserted into the slot, so that the soundproof cover is radially limited to the extension, and then limited to the outer shell, so that the soundproof cover is accurately positioned, and the cup body is covered to achieve isolation of the crushing noise inside the cup body, with a good noise reduction effect. At the same time, it also serves as a guide for users to install the soundproof cover, avoiding the problem of users not installing it properly.

[0025] In a preferred embodiment, the food processor includes a handle located on the side of the cup body, the side wall of the shell is provided with a notch that avoids the lower end of the handle, and the sealing ring is further provided with a third isolation portion located at the notch to isolate the lower end of the handle from the shell.

[0026] By providing a notch on the side wall of the shell to avoid the lower end of the handle, the handle can be arranged vertically, which makes it easier and more fitting to the cup body, and can be fixed reliably. The third isolation part is provided at the notch to isolate the handle and the shell, effectively avoiding resonance noise between the handle and the shell during operation. At the same time, the third isolation part can seal the notch to prevent external debris from entering the shell through the notch, causing cleaning trouble and damaging electrical components such as the motor.

[0027] In a preferred embodiment, the food processor includes a handle located on the side of the cup body, the side wall of the sound insulation cover is provided with a avoidance groove for avoiding the handle, the avoidance groove extends to the opening end of the sound insulation cover, and a sealing strip is provided between the avoidance groove and the handle.

[0028] By setting an avoidance groove on the side wall of the sound insulation cover, the radial size of the sound insulation cover can be reduced, and the size of the outer shell used to support the sound insulation cover can be reduced simultaneously, so that the volume of the whole machine is reduced and it is convenient to move and store. By setting a sealing strip, the gap between the avoidance groove and the handle is sealed, so that a relatively closed noise reduction chamber is formed between the sound insulation cover and the cup body, and the resonance noise between the handle and the sound insulation cover is isolated, further improving the noise reduction effect.

[0029] In a preferred embodiment, the food processor includes a handle located on the side of the cup body, the fixing seat has a radially inward recess, the upper end of the handle is hooked on the cup body, and the lower end of the handle is fixed to the recess by a fastener.

[0030] By arranging a radially inward recess on the fixing seat, the handle can be arranged vertically, and the handle and the cup body are easier to fit together and fit tightly, and the fixation is reliable. The upper end of the handle is hooked on the cup body, and the lower end is fixed to the recess by a fastener. The fixing method is simple, and the handle also strengthens the connection between the cup body and the fixing seat. The general structural strength of the outer shell is relatively weak. The handle is fixed to the fixing seat instead of being fixed to the outer shell, thereby avoiding the outer shell from being broken by stress, and the connection strength is high.

[0031] In a preferred embodiment, the food processor further includes a cup cover covering the cup body, the cup cover and the top wall of the sound insulation cover are respectively provided with an air vent and a mounting hole, the food processor further includes a breathable cover with a breathable channel, the breathable cover is limit-connected to the mounting hole to move with the sound insulation cover, and after the sound insulation cover is installed in place, the lower end of the breathable cover is interference-inserted into the air vent.

[0032] In the present application, a breathable cover with a breathable channel is provided to achieve communication and exhaust between the cup body and the outside world during processing, thereby preventing the dangerous situation caused by excessive pressure in the cup body and improving the safety of use. Different from the prior art, in the prior art, the breathable cover is directly sealed with the breathable hole after avoiding the mounting hole on the sound insulation cover. During use, the breathable cover is often sealed with the breathable hole first, and then the sound insulation cover is installed, and the breathable cover is pressed by the sound insulation cover. Therefore, when the whole machine is finished working, the breathable cover may be sprayed out or loosened from the breathable hole due to the pressure in the cup body when the user removes the sound insulation cover. Moreover, when the pressure in the cup body is relatively low, even if the breathable cover is not sprayed out, the user needs to remove the sound insulation cover first, and then remove the breathable cover. The operation is cumbersome and complicated to use, and the user experience is not good. In the present application, the vent cover is positionally connected to the mounting hole so as to move with the soundproof cover. Therefore, when the user installs the soundproof cover, the vent cover is installed together with the soundproof cover and the lower end is inserted into the vent hole with interference fit, thereby sealing the soundproof cover and the cup body interlayer and preventing moisture from entering the soundproof cover. When the user removes the soundproof cover, the vent cover moves with the soundproof cover and separates from the vent hole, preventing the vent cover from being sprayed out and facilitating user operation.

[0033] More preferably, the breathable cover is integrally formed in the mounting hole;

[0034] Alternatively, the wall of the mounting hole is provided with an annular groove with a notch, and the vent cover is provided with a protrusion protruding radially outward and corresponding to the notch, and the protrusion can be rotated through the notch to be snapped into the annular groove;

[0035] Alternatively, a bearing portion is provided at the edge of the mounting hole, and the vent cover comprises a sealing portion inserted into the vent hole and a radially enlarged overlapping portion connected above the sealing portion, wherein the overlapping portion overlaps above the bearing portion and is attracted to the bearing portion;

[0036] Alternatively, the mounting hole is provided with an internal thread, and the vent cover is provided with an external thread matching the internal thread;

[0037] Alternatively, the breathable cover includes a cover body, a plug body detachably arranged in the cover body, and a sealing member sleeved on the lower part of the cover body, the breathable channel is arranged in the plug body, and the sealing member abuts against the inner wall of the breathable hole.

[0038] The vent cover is integrally formed into the mounting hole, which reduces the number of user steps, improves the user experience, and is more practical and convenient. The vent cover is detachable and can be thoroughly cleaned by screwing the protrusion and annular groove together and magnetically engaging. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The present invention provides a food processing machine in one embodiment. Figure 1 、 2 As shown, it includes a cup body 10 with a built-in crushing knife 11, a heating plate 12 encapsulated at the bottom of the cup body 10, a fixing seat 13 that supports the heating plate 12 and is fixed on the lower part of the cup body 10, and an outer shell 15 that is sleeved on the outside of the fixing seat and connected to the fixing seat. A motor 14 is provided in the outer shell 15, and a rotating shaft driven by the motor 14 passes through the heating plate 12 and is connected to the crushing knife 11. An annular installation gap is formed between the fixing seat 13 and the cup body 10, and a sealing ring 30 is provided at the installation gap. The food processor also includes a sound insulation cover 20 that is buckled onto the outside of the cup body 10. A supporting surface for supporting the sound insulation cover 20 is provided on the top of the outer shell 15. The sealing ring 30 is provided with an extension portion 31 extending to the supporting surface, and the sound insulation cover 20 is pressed against the extension portion 31.

[0054] The utility model provides a food processing machine, by providing a fixing base 13, the fixing base 13 supports the heating plate 12 and is sleeved and fixed on the lower part of the cup body 10, so as to realize reliable assembly of the structure to form a processing cavity for processing food materials, and an annular installation gap is formed between the fixing base 13 and the cup body 10, and a sealing ring 30 is provided at the installation gap, which can seal the installation gap between the fixing base 13 and the cup body 10, thereby avoiding the problem of water entering the fixing base 13 during pouring, overflowing and cleaning to generate odor and breed bacteria, so that the food processing machine is hygienic to use and food safety is ensured. The sealing ring 30 is provided with an extension portion 31 extending onto the support surface. The soundproof cover 20 is pressed against the extension portion 31. Therefore, the soundproof cover 20 forms a flexible contact with the support surface of the housing 15 through the extension portion 31. During the operation of the motor 14, vibrations are generated and transmitted to the housing 15. The vibrations of the housing 15 are absorbed by the extension portion 31 as they continue to be transmitted outward, thereby preventing the soundproof cover 20 from generating resonance noise. Therefore, the resonance noise is eliminated at the source and noise reduction is achieved. In addition, because the extension portion 31 can be fixed in the installation gap by the sealing ring 30 to form a limit, the extension portion 31 is firmly positioned, which can reduce the risk of falling off, and achieve effective and long-term isolation between the soundproof cover 20 and the housing 15, and the structure is reliable. Therefore, the sealing ring 30 integrates the dual functions of sealing and isolating resonance noise, without the need for multiple independent components to achieve this, making the overall structure simple and the installation process easy.

[0055] In a preferred embodiment, the cup body 10 includes a main section, an inwardly contracted transition section, and a contraction section connected in sequence, the sealing ring 30 is sleeved on the transition section, and the fixing seat 13 is sleeved and fixed on the outer periphery of the contraction section to press the sealing ring 30 on the transition section to seal the installation gap.

[0056] Optionally, the fixing seat is threadably connected to the glass body.

[0057] The cup body is provided with an inwardly contracting transition section and contracting section, and the fixing seat 13 is sleeved on the outer periphery of the contracting section, which reduces the radial dimension of the entire device, facilitating a smaller overall size and convenient handling and storage. By sleeve-fitting the sealing ring 30 into the transition section, the fixing seat 13, once in place, presses the sealing ring 30 against the transition section, thereby clamping the sealing ring 30 and strengthening the reliable connection between the sealing ring 30 and the installation gap. Furthermore, the extension portion 31 can be reliably limited by the clamping of the sealing ring 30, thereby reducing the risk of falling off, achieving a reliable isolation effect, and effectively reducing the noise of the entire device.

[0058] Of course, it should be noted that the present invention does not limit the installation method of the sealing ring. In another embodiment, the sealing ring can be inserted into the installation gap after the fixing seat is sleeved on the lower part of the cup body.

[0059] In addition, the present invention does not limit the sealing structure of the sealing ring, for example:

[0060] Implementation Example 1, such as Figure 1-6 As shown, the fixing base 13 is exposed from the top of the housing 15, and a fitting gap is formed between the fixing base 13 and the housing 15. The extension portion 31 extends along the surface of the fixing base 13 and covers the fitting gap. The top of the fixing base 13 is exposed from the housing 15, and a fitting gap is formed at the top of the fixing base 13 and the housing 15. The extension portion 31 extends along the top surface of the fixing base 13 and covers the fitting gap.

[0061] Mounting base 13 is installed outside housing 15, while extension 31 extends along the surface of mounting base 13 to cover the joint. Thus, sealing ring 30 not only seals the installation gap and joint, but also insulates soundproofing cover 20. This single component integrates multiple functions, reducing the number of components and simplifying the installation process. Furthermore, the sealed joint prevents water from entering housing 15 and damaging motor 14, thereby extending the life of the food processor.

[0062] Implementation Example 2, such as Figure 7 As shown, the top of the shell 15 is provided with a retaining wall 154 extending laterally toward the side wall of the cup body 10. The retaining wall 154 covers the top of the fixing seat 13 to hide the fixing seat 13 in the shell 15. The sealing ring 30 includes a first sealing portion 321 clamped by the fixing seat 13 and the cup body 10 and a second sealing portion 322 clamped by the retaining wall 154 and the cup body 10. The extension portion 31 covers the outer surface of the retaining wall 154.

[0063] By providing a retaining wall 154 on the top of the housing 15, the retaining wall 154 covers the fixing base 13 and conceals it in the housing 15, thereby avoiding an exposed gap between the housing 15 and the fixing base 13 and reducing the risk of water intrusion into the housing 15. The sealing ring 30 includes a first sealing portion 321 clamped by the fixing base 13 and the cup body 10 and a second sealing portion 322 clamped by the retaining wall 154 and the cup body 10, thereby improving the sealing effect. At the same time, flexible contact is formed between the cup body 10 and the fixing base 13, and between the retaining wall 154 and the cup body 10, and both can be sealed by a sealing member 1803. The sealing ring 30 also isolates the soundproof cover 20, reducing the number of parts of the entire device, making the structure simpler and easier to assemble. At the same time, the extension portion 31 is more reliably positioned on the support surface, achieving an isolation effect.

[0064] More preferably, if Figure 7 As shown, the retaining wall is overlapped on the top of the fixing seat, and the sealing ring further includes a third isolation portion 323 isolated between the retaining wall and the fixing seat.

[0065] In addition, the present invention does not limit the structure of the extension part. In a preferred embodiment, the shell 15 is provided with a limiting wall extending upward from the supporting surface. The extension part 31 includes a first isolation part 311 extending laterally on the supporting surface and a second isolation part 312 extending vertically along the limiting wall. The sound insulation cover 20 is abutted against the limiting wall through the second isolation part 312.

[0066] By providing a limiting wall extending upward from the supporting surface on the outer shell 15, radial limitation of the sound insulation cover 20 is achieved. The extension portion 31 includes a first isolation portion 311 and a second isolation portion 312. The first isolation portion 311 is located on the supporting surface and extends laterally, which can support the sound insulation cover 20 to achieve axial isolation and limitation between the sound insulation cover 20 and the outer shell 15. The second isolation portion 312 extends vertically along the limiting wall, and the sound insulation cover 20 is abutted against the limiting wall through the second isolation portion 312, so that the sound insulation cover 20 and the limiting wall achieve radial isolation and limitation, further reducing resonance noise, improving noise reduction effect, and improving the installation stability of the sound insulation cover 20.

[0067] Optionally, an annular step 151 is provided on the top of the housing 15, the limiting wall is the step side wall of the annular step 151, and the supporting surface is the step surface of the annular step 151;

[0068] Alternatively, an annular limiting groove is provided on the top of the shell 15, and the open end of the sound insulation cover 20 is inserted into the limiting groove, the limiting wall is the groove wall of the limiting groove, and the supporting surface is the groove bottom wall of the limiting groove.

[0069] Whether the limiting wall and support surface are formed by the annular step 151 or by the limiting groove, both axial and radial isolation and limiting are achieved between the soundproofing cover 20 and the housing 15, ensuring stable installation of the soundproofing cover 20 and reducing operating noise. The provision of the annular step 151 facilitates cleaning of dust accumulated on the support surface. The provision of the limiting groove provides more comprehensive and reliable radial limiting of the soundproofing cover 20.

[0070] In a preferred embodiment, an annular positioning groove 152 for mounting the extension portion 31 is provided on the support surface, the lower end of the extension portion 31 is sunk into the annular positioning groove 152 , and the upper end of the extension portion 31 protrudes from the annular positioning groove 152 .

[0071] By providing an annular positioning groove 152 on the supporting surface, the lower end of the extension part 31 is sunk into the annular positioning groove 152, so that the extension part 31 is clamped by the sealing ring 30 to achieve primary limiting fixation, and the annular positioning groove 152 is used to achieve secondary limiting, further preventing the extension part 31 from moving or loosening, so that the isolation between the sound insulation cover 20 and the outer shell 15 is effective, and the noise reduction effect is achieved. In addition, the upper end of the extension part 31 protrudes from the annular positioning groove 152 to further ensure that the sound insulation cover 20 is supported on the extension part 31 to avoid contact with the outer shell 15, reduce resonance, and reduce noise.

[0072] In a preferred embodiment, an annular slot is provided on the upper surface of the extension portion 31 , and the open end of the sound insulation cover 20 is inserted into the slot.

[0073] By providing an annular slot on the upper surface of the extension portion 31, the open end of the soundproof cover 20 is inserted into the slot, so that the soundproof cover 20 is radially limited to the extension portion 31, and further limited to the outer shell 15, so that the soundproof cover 20 is accurately positioned, covering the cup body 10, isolating the crushing noise in the cup body 10, and achieving a good noise reduction effect. At the same time, it also serves as a guide for the user to install the soundproof cover 20, avoiding the problem of improper installation by the user.

[0074] In a preferred embodiment, for example, in Example 1, Figure 1 As shown, the food processor includes a handle 16 located on the side of the cup body 10, and the side wall of the shell 15 is provided with a gap to avoid the lower end of the handle 16. The sealing ring 30 is also provided with a third isolation portion located at the gap to isolate the lower end of the handle 16 from the shell 15. Optionally, as Figure 3 As shown, the side wall of the soundproof cover 20 is provided with an escape groove 21 for evading the handle 16. The escape groove 21 extends to the open end of the soundproof cover 20. A sealing strip is provided between the escape groove 21 and the handle 16. Optionally, the sealing strip is provided around the handle 16. Optionally, the fixing seat 13 has a radially inward recessed portion, the upper end of the handle 16 is hooked on the cup body 10, and the lower end of the handle 16 is fixed to the recessed portion by a fastener.

[0075] It is understandable that this embodiment is only used to illustrate the installation of the handle 16 and the matching method of the handle 16 and the sealing ring 30 by combining the embodiment 1 as an example for the convenience of description. In fact, it can also be combined with other embodiments of the present invention.

[0076] By providing a notch on the sidewall of the housing 15 that allows for clearance of the lower end of the handle 16, the handle 16 can be arranged vertically, making it easier to fit and securely secure to the cup body 10. A third isolating portion is provided at the notch to isolate the handle 16 from the housing 15, effectively preventing resonance noise between the handle 16 and the housing 15 during operation. At the same time, the third isolating portion can seal the notch, preventing external debris from entering the housing 15 through the notch, causing cleaning difficulties and damaging electrical components such as the motor 14. By providing a clearance groove 21 on the sidewall of the soundproof cover 20, the radial dimension of the soundproof cover 20 can be reduced, and the size of the housing 15 used to support the soundproof cover 20 can also be reduced, reducing the overall size of the device and making it easier to move and store. By providing a sealing strip to seal the gap between the clearance groove 21 and the handle 16, a relatively closed noise reduction chamber is formed between the soundproof cover 20 and the cup body 10, isolating the resonance noise between the handle 16 and the soundproof cover 20 and further enhancing the noise reduction effect. By providing a radially inward recess on the fixing seat 13, the handle 16 can be arranged vertically, and the handle 16 and the cup body 10 can be matched more easily and fit together, and the fixation is reliable. The upper end of the handle 16 is hooked on the cup body 10, and the lower end is fixed to the recess by a fastener. The fixing method is simple. The handle 16 also strengthens the connection between the cup body 10 and the fixing seat 13. The general structural strength of the shell 15 is relatively weak. The handle 16 is fixed to the fixing seat 13 instead of being fixed to the shell 15, thereby avoiding the shell 15 from being broken by stress, and the connection strength is high.

[0077] In a preferred embodiment, for example, in Example 1, Figure 3-6 As shown, the food processor also includes a cup cover 17 that covers the cup body 10. The cup cover 17 and the top wall of the sound insulation cover 20 are respectively provided with an air vent 171 and a mounting hole 22. The food processor also includes a breathable cover 18 with a breathable channel. The breathable cover 18 is limitedly connected to the mounting hole 22 to move with the sound insulation cover 20, and after the sound insulation cover 20 is installed in place, the lower end of the breathable cover 18 is interference-inserted into the breathable hole 171.

[0078] In a preferred embodiment, for example, in Example 1, Figure 3-6 As shown, the food processor also includes a cup cover 17 that covers the cup body 10. The cup cover 17 and the top wall of the sound insulation cover 20 are respectively provided with an air vent 171 and a mounting hole 22. The food processor also includes a breathable cover 18 with a breathable channel. The breathable cover 18 is limitedly connected to the mounting hole 22 to move with the sound insulation cover 20, and after the sound insulation cover 20 is installed in place, the lower end of the breathable cover 18 is interference-inserted into the breathable hole 171.

[0079] It is understandable that the above-mentioned breathable cover 18 structure of the present invention is not limited to being combined with embodiment 1. In fact, it can also be combined with other embodiments of the present invention.

[0080] In a more specific embodiment, Figure 4 As shown, a bearing portion 221 is provided at the edge of the mounting hole 22, and the vent cover 18 includes an inserting portion 181 inserted into the vent hole and a radially enlarged overlapping portion 182 connected above the inserting portion. The overlapping portion 182 is overlapped and limited above the bearing portion 221. Preferably, the bearing portion 221 is recessed downward relative to the top wall of the soundproof cover 20.

[0081] Preferably, the overlapping portion 182 is magnetically connected to the bearing portion 221 .

[0082] like Figure 3-6 As shown, the breathable cover 18 includes a cover body 1801, a plug body 1802 inserted into the cover body, and a seal 1803 sleeved on the lower part of the cover body. The top of the cover body forms a gripping portion, the bottom of the cover body is inserted into the breathable hole, the breathable channel is set in the plug body, and the seal is in contact with the inner wall of the breathable hole.

[0083] The plug-in portion 182 and the overlap portion 182 are integrally formed on the sealing member 1803 , and the lower end of the sealing member 1803 is inserted into the vent hole along with the cover body and is interference-fitted with the vent hole 171 .

[0084] Optionally, the bearing portion 221 is an annular platform surrounding the vent hole or a plurality of bearing sub-plates protruding from the inner wall of the mounting hole.

[0085] In this embodiment, a breathable cover 18 with a breathable channel is provided to achieve communication and exhaust between the cup body 10 and the outside during processing, thereby preventing the dangerous situation caused by excessive pressure in the cup body 10 and improving the safety of use. Different from the prior art, in the prior art, the breathable cover 18 and the mounting hole 22 on the sound insulation cover 20 are avoided and then directly sealed with the breathable hole 171. During use, the breathable cover 18 is often sealed with the breathable hole 171 first, and then the sound insulation cover 20 is installed, and the breathable cover 18 is pressed by the sound insulation cover 20. Therefore, when the whole machine is finished working, the user may remove the sound insulation cover 20 and there is a possibility that the breathable cover 18 will be sprayed out or loosened from the breathable hole 171 due to the pressure in the cup body 10. Moreover, when the pressure in the cup body 10 is relatively low, even if the breathable cover 18 is not sprayed out, the user needs to remove the sound insulation cover 20 first and then remove the breathable cover 18. The operation is cumbersome and complicated to use, and the user experience is not good. In the present application, the vent cover 18 is positionally connected to the mounting hole 22 to move with the soundproof cover 20. Therefore, when the user installs the soundproof cover 20, the vent cover 18 is installed together with the soundproof cover 20 and the lower end is inserted into the vent hole 171 with interference fit, which can seal the interlayer between the soundproof cover 20 and the cup body 10 and prevent moisture from entering the soundproof cover 20. When the user removes the soundproof cover 20, the vent cover 18 moves with the soundproof cover 20 and is separated from the vent hole 171, which is easy to operate and prevents the vent cover 18 from being sprayed out.

[0086] Of course, it should be noted that, in this embodiment, the position-limiting connection method between the vent cover 18 and the mounting hole 22 is not limited to the above-mentioned magnetic attraction connection.

[0087] In another embodiment, the hole wall of the mounting hole is provided with an annular groove having a notch, and the vent cover is provided with a protrusion protruding radially outward and corresponding to the notch, and the protrusion can be rotated through the notch to be snapped into the annular groove and offset from the notch;

[0088] It is understandable that the protrusion and the annular groove can be swapped.

[0089] Of course, in other embodiments, optionally, the breathable cover is integrally formed in the mounting hole; or, an internal thread is provided in the mounting hole, and the breathable cover is provided with an external thread matching the internal thread; or the breathable cover is fixed to the mounting hole by screws.

[0090] Anything not described in this utility model can be achieved by adopting or drawing on existing technologies.

[0091] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0092] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
