Description

Technical Field

[0001] The utility model relates to the field of food processing machines, in particular to a food processing machine with a simple structure. Background Art

[0002] Currently, there are food processors with sound insulation covers on the market. The food processors include a main unit, a blending cup arranged on the main unit, and a sound insulation cover covering the main unit. The sound insulation cover covers the blending cup inside, which can block the noise in the cup body from being transmitted outward, thereby achieving noise reduction.

[0003] Conventional food processors with soundproof covers are provided with seals at the matching positions of the soundproof cover and the main machine, such as the products disclosed in patents CN218074671 U and CN 219109238 U. The provision of the seals will increase the cost of the entire machine on the one hand, and will complicate the structure of the soundproof cover or the main machine on the other hand. For example, in the soundproof cover disclosed in patent CN 218074671U, in order to install the seal on the soundproof cover, an adapter is provided at the bottom end of the soundproof cover, which is connected to the seal through the adapter, and the structure is relatively complex and the cost is relatively high. Utility Model Content

[0004] In order to solve the technical problem in the prior art that a seal is provided between a main unit and a sound insulation cover, which results in a complex structure and high cost, the utility model provides a food processing machine with a simple structure. By eliminating the provision of a seal and utilizing the interference fit between the main unit and the sound insulation cover to achieve the installation of the sound insulation cover, the overall structural configuration of the machine can be simplified and the cost can be reduced while ensuring the sound insulation cover is firmly installed and has a good noise blocking effect.

[0005] The utility model discloses a food processing machine with a simple structure, comprising a main machine, a cup body component arranged above the main machine, and a sound insulation cover mounted above the main machine and covering the outside of the cup body component, the main machine comprising a main machine top surface, a guide surface transitioning downward from the main machine top surface, an assembly surface connected to and extending vertically below the guide surface, and a support platform extending radially outward from the bottom of the assembly surface, the guide surface extending away from the center of the main machine top surface, the assembly surface being used for interference fit with the sound insulation cover, the sound insulation cover being guided toward the support platform by the guide surface, so that when the sound insulation cover is interference fit with the assembly surface, the bottom end of the sound insulation cover is supported on the support platform.

[0006] The food processing machine of the utility model has a simple structure and also has the following additional technical features:

[0007] The inner wall of the soundproof cover is provided with a relief surface for avoiding the guide surface, and a matching surface for interference fit with the assembly surface is provided above the relief surface; the guide surface and the relief surface are arc surfaces or plane surfaces.

[0008] The assembly surface is inclined outward from top to bottom, and the matching surface is matched with the assembly surface.

[0009] The assembly surface is in a square shape along the circumferential direction and surrounds the top surface of the main machine. The assembly surface is interference-fitted with the sound insulation cover at four azimuth angles of the square.

[0010] The four azimuth angles of the square are connected by right-angled sides or arc-shaped sides, and the assembly surface is interference-fitted with the sound insulation cover at the right-angled sides or arc-shaped sides.

[0011] The top surface of the main unit is provided with an upwardly protruding annular positioning ring, and the cup body assembly is provided with a positioning groove that cooperates with the annular positioning ring. The annular positioning ring is eccentrically arranged relative to the center of the top surface of the main unit, and the handle of the cup body assembly is located on the outside of the annular positioning ring and the projection of the handle on the horizontal plane falls within the projection range of the top surface of the main unit on the horizontal plane.

[0012] The wall thickness of the soundproof cover is 2-4 mm.

[0013] The minimum distance from the outer wall of the cup body of the cup body assembly to the inner wall of the sound insulation cover is not less than 5 mm.

[0014] The soundproof cover is in a straight cylindrical shape or the lower end of the soundproof cover is radially enlarged relative to the upper end.

[0015] The host also includes a boss arranged below the support platform and extending radially outward from one side, and an operation panel is arranged on the top of the boss.

[0016] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0017] 1. The food processing machine of the utility model has a simple structure. In order to solve the technical problem of the prior art that a seal is provided between the main machine and the sound insulation cover, which leads to a complex structure and high cost, the seal is eliminated and the installation of the sound insulation cover is achieved by utilizing the interference fit between the main machine and the sound insulation cover. On the premise of ensuring the stable installation of the sound insulation cover and the noise blocking effect of the sound insulation cover, the structural configuration of the whole machine can be simplified and the cost can be reduced.

[0018] By setting the guide surface, it is convenient to guide the sound insulation cover downward for assembly, which can reduce the difficulty of aligning the sound insulation cover and improve the assembly efficiency. When the sound insulation cover is installed in place, the sound insulation cover and the assembly surface have an interference fit and the bottom end of the sound insulation cover is supported on the support table. The support of the sound insulation cover is stable and the noise is not easy to be transmitted from between the sound insulation cover and the assembly surface when the machine is working, which can ensure the noise reduction effect.

[0019] 2. In order to facilitate the smooth assembly of the soundproof cover, as a preferred embodiment, the inner wall of the soundproof cover is provided with a relief surface for avoiding the guide surface, and a mating surface with interference fit with the assembly surface is provided above the relief surface; the guide surface and the relief surface are arcuate surfaces or planes. It can be understood that the relief surface can prevent assembly interference, avoid the soundproof cover from getting stuck along the guide surface when the soundproof cover is guided, and avoid excessive friction between the soundproof cover and the guide surface causing wear, which is conducive to smooth assembly, improves assembly efficiency, and reduces wear. The relief surface is compatible with the guide surface, and both can be arcuate surfaces or planes for easy processing.

[0020] As a preferred embodiment of this embodiment, the assembly surface is inclined outward from top to bottom, and the mating surface is matched with the assembly surface. By setting the inclined assembly surface and the mating surface, when the mating surface is close to the assembly surface, the center of gravity of the soundproof cover can be pushed closer to the center of the host, which can prevent the soundproof cover from tipping over from one side, thereby improving its stability in use.

[0021] 3. As a preferred embodiment, the assembly surface is circumferentially in a square shape surrounding the top surface of the host, and the assembly surface is interference-fitted with the sound insulation cover at the four azimuth angles of the square. In this embodiment, the host shape can be used to make the host and the sound insulation cover interference-fit at a specific position. Since the matching points are distributed at four azimuth angles, the sound insulation cover can be tightly fastened to the host along the circumference, and the installation stability can be improved.

[0022] As a preferred embodiment of the present embodiment, the four azimuth angles of the square are connected by right-angled sides or arcuate sides, and the assembly surface is interference-fitted with the sound insulation cover at the right-angled sides or arcuate sides. By increasing the interference-fit locations between the host and the sound insulation cover, the installation stability of the sound insulation cover can be enhanced, and at the same time, the noise transmitted from the matching gap between the host and the sound insulation cover can be reduced, thereby improving the noise reduction effect.

[0023] 4. As a preferred embodiment, the top surface of the main unit is provided with an upwardly protruding annular positioning ring, the cup assembly is provided with a positioning groove matched with the annular positioning ring, the annular positioning ring is eccentrically arranged relative to the center of the top surface of the main unit, the handle of the cup assembly is located outside the annular positioning ring and the projection of the handle on the horizontal plane falls within the projection range of the top surface of the main unit on the horizontal plane. Under the premise of minimizing the top surface of the main unit, the cup assembly can be completely within the range of the top surface of the main unit, ensuring that the soundproof cover completely covers the cup assembly inside to reduce working noise.

[0024] 5. As a preferred embodiment, the wall thickness of the soundproof cover is 2-4 mm. By reasonably setting the wall thickness, the coordination between the soundproof cover and the host can be strengthened to avoid the situation where the soundproof cover is light in weight when the wall thickness is small, and the soundproof cover and the host are easily resonated at the same frequency when the host vibrates, which is conducive to reducing the probability of resonance of the structural parts and optimizing noise reduction.

[0025] 6. As a preferred embodiment, the minimum distance between the outer wall of the cup body of the cup body assembly and the inner wall of the soundproof cover is not less than 5 mm. This can prevent the soundproof cover from easily hitting the cup body and causing scratches when installing and removing it, and can enhance the protection of the cup body. If the distance between the outer wall of the cup body and the inner wall of the soundproof cover is too small, it will be detrimental to the heat preservation and noise isolation of the cup body.

[0026] 7. As a preferred embodiment, the soundproof cover is straight-cylindrical or the lower end of the soundproof cover is radially enlarged relative to the upper end. Specifically, when a straight-cylindrical soundproof cover is used, it is easy to process; when a soundproof cover with a gradually enlarged lower end is used, after the soundproof cover is installed, the center of gravity of the soundproof cover is close to the center of the host, which can prevent the soundproof cover from tipping over from one side and improve its stability in use.

[0027] 8. As a preferred embodiment, the host further comprises a boss extending radially outward from one side and arranged below the support platform, and an operation panel is arranged on the top of the boss. Since the boss only extends from one side, the radial volume of the host can be reduced, which is conducive to the miniaturization of the host, and is conducive to reducing the weight of the host, and is convenient for users to carry.

[0047] like Figure 1 to Figure 2 As shown, the present application provides a food processing machine with a simple structure, including a main machine 10, a cup body assembly 11 arranged above the main machine 10, and a sound insulation cover 12 mounted above the main machine 10 and covering the outside of the cup body assembly 11, the main machine 10 includes a main machine top surface 13, a guide surface 14 transitioning downward from the main machine top surface 13, an assembly surface 15 connected to and extending vertically below the guide surface 14, and a support platform 16 extending radially outward from the bottom of the assembly surface 15, the guide surface 14 extends away from the center of the main machine top surface 13, the assembly surface 15 is used to have an interference fit with the sound insulation cover 12, and the sound insulation cover 12 is guided toward the support platform 16 by the guide surface 14, so that when the sound insulation cover 12 is in interference fit with the assembly surface 15, the bottom end of the sound insulation cover 12 is supported on the support platform 16.

[0048] The food processing machine of the utility model has a simple structure, in order to solve the technical problem of the prior art that a seal is provided between the main unit 10 and the sound insulation cover 12, which leads to a complex structure and high cost. By eliminating the provision of the seal, the installation of the sound insulation cover 12 is achieved by utilizing the interference fit between the main unit 10 and the sound insulation cover 12. On the premise of ensuring that the sound insulation cover 12 is firmly installed and has a noise-blocking effect, the overall structural configuration of the machine can be simplified and the cost can be reduced.

[0049] By providing the guide surface 14, it is convenient to guide the sound insulation cover 12 to be assembled downward, which can reduce the difficulty of aligning the sound insulation cover 12 and improve the assembly efficiency. When the sound insulation cover 12 is installed in place, the sound insulation cover 12 and the assembly surface 15 have an interference fit and the bottom end of the sound insulation cover 12 is supported on the support platform 16. The sound insulation cover 12 is stably supported and the noise is not easily transmitted from between the sound insulation cover 12 and the assembly surface 15 when the machine is working, which can ensure the noise reduction effect.

[0050] like Figure 1 As shown, when the machine is in use, after the cup body assembly 11 is placed in place on the main unit 10, the soundproof cover 12 is installed from above, and the soundproof cover 12 is installed by making the soundproof cover 12 and the assembly surface 15 of the main unit 10 interfere with each other and the bottom end of the soundproof cover 12 is supported on the support platform 16, and the machine can start working. Based on the interference fit, the vibration of the main unit 10 will not form a high-frequency impact on the soundproof cover 12 to cause air vibration and produce abnormal noise, and the crushing noise is blocked inside, which can greatly reduce the working noise and improve the user experience. The lower end of the soundproof cover 12 is open, and the top of the soundproof cover 12 can adopt a closed structure, and a feeding port can also be set to cooperate with the feeding cover to meet the user's feeding needs during the processing. Since the sealing member is eliminated, the radial dimension of the support platform 16 can be relatively reduced (when a sealing ring is sleeved around the assembly surface 15, the sealing ring has a certain thickness and will inevitably occupy the radial dimension of the support platform 16. The support platform 16 needs to extend a larger dimension to ensure effective support for the soundproof cover 12), which is beneficial to reducing the radial volume of the host 10. During specific assembly, the lower inner wall of the soundproof cover 12 moves downward along the guide surface 14 until the soundproof cover 12 and the assembly surface 15 are interference-fitted, and preferably, when the soundproof cover 12 and the assembly surface 15 are interference-fitted in place, the soundproof cover 12 is just supported on the support platform 16.

[0051] In order to facilitate the smooth assembly of the soundproof cover 12 , as a preferred embodiment, the inner wall of the soundproof cover 12 is provided with an avoidance surface 17 for avoiding the guide surface 14 , and a fitting surface 18 is provided above the avoidance surface 17 for interference fit with the assembly surface 15 .

[0052] like Figure 1 As shown, the avoidance surface 17 is arranged near the bottom end of the soundproof cover 12. When the user places the soundproof cover 12 downward, the avoidance surface 17 contacts the guide surface 14 first to guide the soundproof cover 12 to move downward. It can be understood that the avoidance surface 17 can prevent assembly interference, and can prevent the soundproof cover 12 from being stuck along the guide surface 14 when the soundproof cover 12 is guided, and the soundproof cover 12 and the guide surface 14 from excessive friction and wear, which is conducive to smooth assembly, improves assembly efficiency, and reduces wear.

[0053] Specifically, the guide surface 14 is inclined from top to bottom in a direction away from the center of the host 10, and correspondingly, the avoidance surface 17 is inclined from top to bottom in a direction away from the center of the soundproof cover 12, and the two have the same inclination direction. Further, the guide surface 14 and the avoidance surface 17 can both be curved surfaces or planes, or one of them can be a curved surface and the other can be a plane. Further, the top surface 13 of the host and the guide surface 14 are connected by a rounded transition, so that even when the soundproof cover 12 first contacts the top surface 13 of the host, the soundproof cover 12 can move smoothly to the guide surface 14 when moving along the top surface 13 of the host, which can reduce the wear between the structural parts.

[0054] As a preferred embodiment of the present embodiment, the assembly surface 15 is inclined outward from top to bottom, and the matching surface 18 is matched with the assembly surface 15 .

[0055] By providing the inclined assembly surface 15 and the mating surface 18, when the mating surface 18 is close to the assembly surface 15, the center of gravity of the soundproof cover 12 can be urged to move closer to the center of the host 10, thereby preventing the soundproof cover 12 from tipping over from one side and improving its stability in use. Figure 1 As shown, the assembly surface 15 is tilted outward from top to bottom, which means that the assembly surface 15 is tilted from top to bottom in a direction away from the center of the host 10, and correspondingly, the mating surface 18 has the same tilt direction, so that the mating surface 18 is closely attached to the assembly surface 15 when the two are interference-fitted. Figure 1 As shown, the inner diameter of the soundproof cover 12 can gradually increase from top to bottom.

[0056] It is understandable that in other embodiments, the assembly surface 15 may also be a vertical plane, in which case the mating surface 18 is also a vertical plane, and the soundproof cover 12 may be configured as a straight cylinder structure (with uniform inner diameter).

[0057] As a preferred embodiment, the assembly surface 15 is circumferentially in a square shape surrounding the main machine top surface 13 , and the assembly surface 15 is interference-fitted with the sound insulation cover 12 at four azimuth angles of the square.

[0058] like Figure 1 As shown, in this embodiment, the shape of the host 10 can be used to make the host 10 and the sound insulation cover 12 have an interference fit at a specific position. Since the fitting points are distributed at four azimuth angles, it can be ensured that the sound insulation cover 12 is tightly fastened to the host 10 along the circumferential direction, and the installation stability is improved.

[0059] Furthermore, the four azimuth angles of the square are connected by right-angled sides or arcuate sides, and the assembly surface 15 is interference-fitted with the soundproof cover 12 at the right-angled sides or arcuate sides. By increasing the interference-fit locations between the host 10 and the soundproof cover 12, the installation stability of the soundproof cover 12 can be enhanced, and at the same time, the noise transmitted from the matching gap between the host 10 and the soundproof cover 12 can be reduced, which can improve the noise reduction effect.

[0060] When the main unit 10 is square, the assembly surface 15 includes four arc corners 151 and four edges 152. The arc corners 151 and the edges 152 are alternately connected. The edges 152 can be straight or have a certain curvature. The soundproof cover 12 and the assembly surface 15 are interference fit at least at the four arc corners 151.

[0061] Of course, in other embodiments, the main unit 10 may also be circular, in which case the assembly surface 15 is circular and surrounds the main unit top surface 13 along the circumferential direction, and the assembly surface 15 may completely have an interference fit with the soundproof cover 12 .

[0062] As a preferred embodiment, the main unit top surface 13 is provided with an upwardly protruding annular positioning ring 131, the cup body assembly 11 is provided with a positioning groove cooperating with the annular positioning ring 131, the annular positioning ring 131 is eccentrically arranged relative to the center of the main unit top surface 13, the handle 111 of the cup body assembly 11 is located on the outside of the annular positioning ring 131 and the projection of the handle 111 on the horizontal plane falls within the projection range of the main unit top surface 13 on the horizontal plane.

[0063] In the prior art, when the annular positioning ring 131 is set in the central area of ​​the main unit top surface 13, a larger space needs to be set around the outer side of the annular positioning ring 131 on the main unit top surface 13 to correspond to the radial size of the handle 111, so that the soundproof cover 12 can completely cover the cup body assembly 11. This solution requires a larger main unit top surface 13, resulting in an excessively large radial size of the main unit 10.

[0064] like Figure 1 As shown, the annular positioning ring 131 is eccentrically arranged relative to the center of the main unit top surface 13. Under the premise of minimizing the main unit top surface 13, the cup body assembly 11 can be completely within the range of the main unit top surface 13, ensuring that the soundproof cover 12 completely covers the cup body assembly 11, thereby reducing working noise.

[0065] As a preferred embodiment, the wall thickness of the soundproof cover 12 is 2-4 mm. By reasonably setting the wall thickness, the coordination between the soundproof cover 12 and the host 10 can be strengthened to avoid that the soundproof cover 12 is light when the wall thickness is small, and the soundproof cover 12 and the host 10 are easily resonated at the same frequency when the host 10 vibrates, which is conducive to reducing the probability of resonance of the structural parts and optimizing noise reduction. Optionally, the wall thickness of the soundproof cover 12 is 2 mm, 2.5 mm, 3 mm, 4 mm, etc.

[0066] As a preferred embodiment, the minimum distance from the outer wall of the cup body 112 of the cup body assembly 11 to the inner wall of the soundproof cover 12 is not less than 5 mm. In this way, it is possible to avoid scratches caused by the cup body 112 when the soundproof cover 12 is installed and removed, and the protection of the cup body 112 can be strengthened. If the distance between the outer wall of the cup body 112 and the inner wall of the soundproof cover 12 is too small, it is not conducive to the heat preservation and noise isolation of the cup body 112. Specifically, when the cup body 112 adopts a straight cup, except for one side where the handle 111 is set, the distance between the outer wall of the cup body 112 and the inner wall of the soundproof cover 12 remains unchanged or gradually changes in the vertical direction (depending on the change in the inner diameter of the soundproof cover 12); when the cup body 112 is provided with a cup spout, the minimum distance from the outer wall of the cup body 112 to the inner wall of the soundproof cover 12 can refer to the distance from the outer end of the cup spout to the inner wall of the soundproof cover 12. The above distance from the outer wall of the cup body 112 to the inner wall of the soundproof cover 12 refers to the parameter after the soundproof cover 12 is installed in place.

[0067] As a preferred embodiment, the soundproof cover 12 is straight-cylindrical or the lower end of the soundproof cover 12 is radially enlarged relative to the upper end. Specifically, when a straight-cylindrical soundproof cover 12 is used, it is easy to process; when a soundproof cover 12 with a gradually enlarged lower end is used, after the soundproof cover 12 is installed, the center of gravity of the soundproof cover 12 is close to the center of the host 10, which can prevent the soundproof cover 12 from tipping over from one side and improve its stability in use.

[0068] As a preferred embodiment, the host 10 further includes a boss 19 disposed below the support platform 16 and extending radially outward from one side, and an operation panel is disposed on the top of the boss 19 .

[0069] like Figure 1 As shown, since the boss 19 extends only from one side, the radial volume of the host 10 can be reduced, which is conducive to the miniaturization of the host 10, and is conducive to reducing the weight of the host 10, and is convenient for users to carry. The setting of the boss 19 provides space for users to operate, and provides feedback to users through the display structure (such as icon lighting), which can improve the user experience.

[0070] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to it based on the present utility model. Therefore, these modifications or improvements made without departing from the spirit of the present utility model are within the scope of protection claimed by the present utility model.
