Description

Technical Field

[0001] This utility model belongs to the field of small household appliance technology, specifically relating to a low-noise baby food processor. Background Technology

[0002] As people's demands for the safety and comfort of infant food processing continue to rise, baby food processors have become one of the most common kitchen appliances in households. Existing baby food processors typically include a motor head, a motor-driven blending assembly, and a processing cup for holding ingredients. The motor head drives the blending blades to rotate within the processing cup via power transmission, achieving the pulverization and blending of ingredients. However, in actual use, the noise generated by the motor head and processing cup during operation can easily be transmitted directly to the external environment through the machine body. In particular, the mechanical noise and airflow vibration noise generated by the high-speed operation of the motor can reflect and diffuse in open spaces, resulting in significant overall noise levels. The body structure of existing baby food processors is mostly flat or open-framed, lacking effective noise insulation design, causing noise to diffuse directly outwards during operation. This not only affects the infant's resting environment but also reduces the user experience. In summary, existing baby food processors generally suffer from problems such as ineffective noise transmission path isolation and inadequate sound insulation structures. Utility Model Content

[0003] In order to overcome at least one of the defects mentioned above in the prior art, the present invention provides a low-noise baby food maker, which forms a C-shaped vertical wall on the machine body to partially surround the processing cup, thereby blocking the direct transmission of noise and reducing the overall operating noise of the machine.

[0004] The technical solution adopted by this utility model to solve its problem is: A low-noise baby food processor includes: a head; a processing cup, the head being connected above the processing cup; and a body, the body having a C-shaped vertical wall for noise reduction, the C-shaped vertical wall having a lateral opening, the processing cup being disposed within the area enclosed by the C-shaped vertical wall, the C-shaped vertical wall extending upward from the bottom of the body and forming an upward opening, the upper end of the C-shaped vertical wall extending at least to the upper middle part of the processing cup.

[0005] As an optional implementation, the radial dimension of the processing cup is smaller than the radial dimension of the C-shaped vertical wall, so that a buffer gap is formed between the processing cup and the C-shaped vertical wall.

[0006] As an optional implementation, the C-shaped vertical wall includes an outer wall and an inner wall, which are spaced apart in the radial direction to form a double-layer hollow structure. The radial dimension of the inner wall is larger than the radial dimension of the processing cup.

[0007] As an optional implementation, the upper end of the outer wall is higher than the upper end of the inner wall, and an arc-shaped step surface is formed between the outer wall and the inner wall, which abuts against the lower end of the machine head.

[0008] As an optional implementation, the upper edge of the outer wall and the upper edge of the inner wall are respectively inclined in the direction toward the center of the processing cup to form a chamfer.

[0009] As an optional implementation, the outer wall and / or inner wall are provided with a number of reinforcing ribs, which are located inside the double-layer hollow structure of the C-shaped vertical wall, and the number of reinforcing ribs extend from the bottom of the fuselage to the top of the C-shaped vertical wall along the height direction of the C-shaped vertical wall.

[0010] As an optional implementation, a U-shaped groove with an upward opening is formed at the bottom of the fuselage. The two ends of the U-shaped groove are respectively connected to the two vertical parts of the C-shaped wall, so that the U-shaped groove and the C-shaped wall together form an integrated enclosure structure.

[0011] As an alternative implementation, the U-shaped groove has a clearance groove in the middle, which extends along the thickness direction of the machine body to avoid the handle part of the processing cup.

[0012] As an optional implementation, the outer edges of the vertical sections on both sides of the C-shaped wall are provided with rounded corners.

[0013] As an optional implementation, the C-shaped vertical wall covers the circumference of the processing cup at an angle of not less than 180°.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By incorporating a C-shaped vertical wall extending upwards from the bottom of the machine body, the processing cup is partially enclosed in the space. The C-shaped vertical wall can block the propagation path of noise when the baby food maker is working, reducing the direct outward diffusion of noise, thereby effectively reducing the external noise during the operation of the baby food maker and improving the overall sound insulation performance and user comfort.

[0023] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0024] See embodiments of this utility model. Figures 1 to 5 A low-noise baby food processor is disclosed. The processor includes a head 1, a processing cup 2, and a body 3. The head 1 is mounted above the processing cup 2. The head 1 drives the mixing blades to rotate, thus mixing and pulverizing the ingredients. The body 3 forms a C-shaped wall 31. The C-shaped wall 31 is arranged circumferentially around the body 3, enclosing a surrounding area. The processing cup 2 is located within this surrounding area. A lateral opening 316 is provided on one side of the C-shaped wall 31. The lateral opening 316 forms a viewing area, allowing the user to observe the mixing process within the processing cup 2, and also provides a passageway when installing or removing the processing cup 2. The C-shaped wall 31 extends upwards from the bottom of the body 3, forming an upward opening. The upper end of the C-shaped wall 31 reaches the upper-middle part of the processing cup 2. The combination of the head 1, processing cup 2, and body 3 forms a compact overall structure. The C-shaped wall 31 maintains ease of operation while blocking direct noise transmission, reducing the overall operating noise of the machine.

[0025] In one implementation, see [reference] Figure 1 and Figure 4The processing cup 2 and the C-shaped vertical wall 31 are arranged at intervals in the radial direction. The radial dimension of the processing cup 2 is smaller than that of the C-shaped vertical wall 31, thus forming a buffer gap 33 between them. The buffer gap 33 is continuously distributed along the circumference of the processing cup 2, penetrating between the outer wall of the processing cup 2 and the inner wall of the C-shaped vertical wall 31. The buffer gap 33 is used to form a buffer space during the operation of the baby food machine, so that the vibration and small displacement generated by the processing cup 2 during the stirring process are not directly transmitted to the machine body 3, thereby reducing the noise caused by structural resonance. In addition, the buffer gap 33 also provides a certain amount of air circulation space, which facilitates the dissipation of heat generated by the machine head 1 through the outer wall of the processing cup 2, improving the overall heat dissipation performance. Optionally, the width of the buffer gap 33 can be adjusted according to the machine size and the capacity of the processing cup 2. If the gap is too small, it will lead to enhanced resonance; if it is too large, it will affect the coating effect. By reasonably setting the gap size, a balance can be achieved between noise reduction, stability and heat dissipation. Elastic buffers or flexible anti-vibration strips can be installed in the buffer gap 33 to further suppress mechanical vibration during the processing. A flow guide hole structure can also be set at the bottom of the gap to drain liquid during cleaning and prevent water accumulation. Through the above structure, the buffer gap 33 not only forms a buffer zone between the processing cup 2 and the C-shaped vertical wall 31, but also plays a comprehensive role in isolating resonance, improving heat dissipation and facilitating cleaning, making the baby food machine run more smoothly, quietly and reliably.

[0026] In one implementation, see [reference] Figure 3 The C-shaped vertical wall 31 includes an outer wall 311 and an inner wall 312. The outer wall 311 and the inner wall 312 are arranged radially at intervals, forming a double-layer hollow structure. The outer wall 311 and the inner wall 312 extend substantially parallel in the height direction and together enclose the hollow cavity. The radial dimension of the inner wall 312 is larger than the radial dimension of the processing cup 2, and the processing cup 2 is located in the inner region of the inner wall 312. The double-layer hollow structure forms an air gap during the operation of the food preparation machine. The air gap has a damping effect on the transmission of noise and vibration, which can reduce the propagation intensity of sound waves in the vertical wall. Optionally, the hollow cavity between the outer wall 311 and the inner wall 312 can be an air gap structure, or it can be filled with sound insulation material or a foamed buffer layer, such as ethylene-vinyl acetate copolymer foam, polyurethane foam, or thermoplastic elastomer material, to enhance vibration reduction and sound absorption effects. The outer wall 311 and the inner wall 312 can be connected and formed by integral injection molding, welding, snap-fitting or gluing to adapt to different manufacturing processes. Through the above structure, the C-shaped vertical wall 31 forms a double-layer hollow structure with an air gap, which effectively reduces the transmission of processing noise and improves the quiet performance of the baby food maker while maintaining the lightweight body.

[0027] In one implementation, see [reference] Figure 2 and Figure 3The upper height of the outer wall 311 is greater than the upper height of the inner wall 312, forming an arc-shaped step surface 313 between them. The arc-shaped step surface 313 extends continuously along the circumference of the C-shaped vertical wall 31, forming an overall horizontal arc-shaped structure. The lower end of the machine head 1 abuts against the arc-shaped step surface 313. The arc-shaped step surface 313 is used to define the installation position of the machine head 1 in the vertical direction, enabling the machine head 1 to be stably positioned during assembly and preventing assembly misalignment that could lead to poor sealing or abnormal noise. The contact between the machine head 1 and the arc-shaped step surface 313 prevents the machine head 1 from directly pressing against the processing cup 2, thereby preventing the processing cup 2 from breaking due to vibration or concentrated stress during operation. Optionally, the upper surface of the arc-shaped step surface 313 can be a flat or slightly arc-shaped structure, or a flexible sealing ring can be provided to achieve buffering and sealing functions after the machine head 1 is assembled. The sealing ring can be made of ethylene-vinyl acetate copolymer rubber, silicone, or thermoplastic elastomer to prevent liquid or noise leakage through gaps. The curved step surface 313 and the outer wall 311 can be integrally injection molded, or they can be connected into a whole by plug-in or hot-melt welding to adapt to different manufacturing process requirements. Through the above structure, the curved step surface 313 not only achieves precise positioning and stable support of the machine head 1, but also effectively reduces the transmission path of operating vibration, prevents the processing cup 2 from being damaged by pressure, and further improves the structural stability and quiet performance of the baby food machine.

[0028] In one implementation, see [reference] Figure 2 The upper edges of the outer wall 311 and the inner wall 312 are respectively inclined towards the center of the processing cup 2 to form chamfers 314. Chamfers 314, without affecting the function of the C-shaped vertical wall 31, achieve smooth assembly and optimized appearance, improving the structural details and ease of use of the baby food processor. Optionally, the inclination angle of chamfers 314 can be designed according to the thickness of the outer wall 311 and the inner wall 312 and the installation space. Chamfers 314 can adopt a straight, curved, or multi-segment transition structure to adapt to different mold forming processes. The upper edge of chamfers 314 can also be polished or micro-frosted to improve the tactile feel and appearance. Chamfers 314 can be integrated with the curved stepped surface 313 as a transition surface, or they can be formed separately and welded or glued to the main body of the vertical wall to meet different manufacturing methods and appearance design requirements.

[0029] In one implementation, see [reference] Figure 3The bottom of the body 3 forms an upward-opening U-shaped groove 32. The two ends of the U-shaped groove 32 connect to the two vertical sections 315 of the C-shaped wall 31, forming a continuous, integrated enclosure structure. The U-shaped groove 32 creates a recessed space in the bottom area to allow for clearance between the bottom of the processing cup 2. This structure allows the body 3 to maintain a compact shape while providing installation space for the bottom protrusion or positioning part of the processing cup 2, ensuring the processing cup 2 can be stably placed within the enclosure area of ​​the C-shaped wall 31 without interference from the bottom of the body. Optionally, the depth and width of the U-shaped groove 32 can be adjusted according to the bottom structure of the processing cup 2 to accommodate different models of processing cups. The bottom of the groove can be equipped with anti-slip pads, drainage holes, or heat dissipation holes to improve stability and ease of use. The U-shaped groove 32 and the C-shaped wall 31 can be manufactured using a single injection molding process, or assembled into a whole by screw connection, snap-fit ​​locking, or hot-melt welding to meet different manufacturing process requirements. Through the above structure, the U-shaped groove 32 and the C-shaped vertical wall 31 together form a complete surrounding frame, which enables the lower structure of the body 3 to provide stable support and also allows space to be avoided for the bottom of the processing cup 2, thereby improving assembly accuracy and structural stability while maintaining the continuity of appearance.

[0030] In one implementation, see [reference] Figure 3 and Figure 5 A clearance groove 321 is provided in the middle of the U-shaped groove 32. The clearance groove 321 extends along the thickness direction of the body 3, forming a local recessed space. The clearance groove 321 communicates with the U-shaped groove 32 and is used to avoid interference with the handle of the processing cup 2 during installation. With this structure, when the processing cup 2 is placed in the area surrounded by the C-shaped vertical wall 31, its handle can be naturally embedded in the clearance groove 321, thereby avoiding interference between the handle and the body 3. The clearance groove 321 ensures smooth assembly and disassembly of the processing cup 2, preventing scratches or assembly resistance caused by structural interference. This structure also ensures the orientation of the processing cup 2, enabling accurate positioning of the cup body and improving assembly consistency and ease of operation. Optionally, the shape of the clearance groove 321 can be a rectangular groove, an arc groove, or a stepped groove to accommodate handles of different shapes. The depth of the clearance groove 321 can be adjusted according to the thickness of the handle of the processing cup 2. The inner wall of the clearance groove 321 can be fitted with a cushioning layer or decorative parts to prevent the handle of the processing cup 2 from directly contacting the machine body 3 during placement. The cushioning layer can be made of ethylene-vinyl acetate copolymer rubber, silicone, or thermoplastic elastomer material, taking into account both shock absorption and aesthetics. Through the above structure, the clearance groove 321 provides a reasonable embedding space for the handle of the processing cup 2, improving the assembly convenience and user experience of the baby food maker.

[0031] In one implementation, see [reference] Figure 4The outer edges of the vertical sections 315 on both sides of the C-shaped wall 31 are rounded. The rounded corners extend continuously along the height of the vertical section 315, forming a smooth transition surface between the outer surface of the wall and the side. The rounded corners eliminate sharp corners at the edges of the vertical section 315, preventing stress concentration during molding or use, thus improving the lifespan of the machine. This structure also prevents users from touching sharp edges when moving or cleaning the baby food maker, improving safety and handling comfort. The rounded corners also make the overall lines of the C-shaped wall 31 more rounded, improving the visual smoothness of the machine's appearance and making the baby food maker's design more in line with the ergonomic and aesthetic requirements of home appliances. Optionally, the radius of the rounded corners can be adjusted according to the wall thickness and molding process. The rounded corners can be arc-shaped, rounded R-corners, or multi-segment transition surfaces to adapt to different molding requirements. The outer surface of the vertical section 315 can also be treated with spraying, polishing, or fine sanding processes to make the appearance more delicate and uniform. Through the above structure, the rounded corner transition of the vertical part 315 not only improves the appearance quality and safety of the fuselage 3, but also improves the stress distribution of the vertical wall during the molding process, ensuring the stability of the fuselage structure and its long-term reliability.

[0032] In one implementation, see [reference] Figure 1 The C-shaped vertical wall 31 forms a surrounding structure around the processing cup 2 in the circumferential direction, with an enclosure angle of not less than 180°. While forming the enclosure, the vertical wall 31 also forms a side opening 316, maintaining the visibility and operability of the processing cup 2. Users can observe the processing status or disassemble the cup through the side opening, thus achieving a balance between ease of use and noise isolation performance. Optionally, the enclosure angle can be adjusted between 180° and 240° to accommodate different sizes of processing cups 2. A smaller angle expands the visibility range, while a larger angle enhances the noise shielding effect. The two vertical sections 315 on both sides of the vertical wall 31 can be designed as arc-shaped, zigzag-shaped, or segmented transition shapes according to the change in the enclosure angle, balancing a streamlined appearance with structural stability. Through the above structure, the C-shaped vertical wall 31 ensures noise control while balancing visibility and ease of operation, achieving a reasonable balance between structural stability, user experience, and aesthetic harmony in the baby food processor.

[0033] In one implementation, see [reference] Figure 3A plurality of reinforcing ribs 317 are provided on the outer wall 311 and / or inner wall 312 of the C-shaped vertical wall 31. The reinforcing ribs 317 are located within the double-layered hollow structure of the vertical wall 31, arranged along the height direction of the vertical wall 31, extending from the bottom of the machine body 3 to the top of the vertical wall 31. The reinforcing ribs 317 are used to enhance the overall rigidity and stability of the vertical wall. This structure can effectively suppress the deformation and resonance of the vertical wall during the operation of the supplementary food machine, reducing the generation of vibration noise. The setting of the reinforcing ribs 317 can also disperse the stress concentration of the vertical wall under stress, keeping the machine body 3 structurally stable during long-term use and preventing fatigue cracking of the vertical wall due to repeated vibration. Optionally, the reinforcing ribs 317 can be arranged on the inner wall 312 or the outer wall 311 respectively. When the reinforcing ribs 317 are only installed on the inner wall 312, they primarily resist vibrations near the processing cup 2. When they are only installed on the outer wall 311, they enhance the support capacity of the outer casing. When reinforcing ribs 317 are installed on both the outer wall 311 and the inner wall 312, the double-layer rib structure forms a longitudinal frame within the hollow cavity, further improving the bending stiffness and resonance suppression effect of the vertical wall. The number of reinforcing ribs 317 can be determined based on the width and height of the vertical wall 31. The reinforcing ribs 317 can be evenly spaced or asymmetrically arranged according to the noise propagation path or stress distribution. The cross-sectional shape of the reinforcing ribs 317 can be rectangular, trapezoidal, or arc-shaped to balance support strength and smooth appearance. The reinforcing ribs 317 can be integrally connected to the vertical wall through injection molding, welding, or bonding to adapt to different process requirements. Through the above structure, the reinforcing rib 317 forms a longitudinally reinforced frame inside the double-layer hollow vertical wall, which improves the structural strength and vibration resistance of the C-shaped vertical wall 31 without changing the overall shape of the body 3, so that the baby food machine can maintain a stable and low-noise working state during operation.

[0034] In some other embodiments, an acoustic energy-absorbing layer may be provided on the inner wall of the fuselage 3 or the inner surface of the C-shaped vertical wall 31. The acoustic energy-absorbing layer includes a porous structure or a microcavity structure to reduce the reflection and resonance of sound waves inside the vertical wall. This energy-absorbing layer can be obtained by laser micro-perforation, foaming, or forming an internal cavity during material injection molding. The energy-absorbing layer forms an integral structure with the main body of the vertical wall, without affecting the appearance or overall strength. Sound waves are dispersed and attenuated through the porous channels during transmission, thereby reducing mid-to-high frequency noise. Optionally, this energy-absorbing layer can be used simultaneously with a double-layer hollow structure to achieve multi-level sound insulation effects.

[0035] In summary, the low-noise baby food maker provided by this utility model has the following technical effects: (1) The design of forming a C-shaped vertical wall 31 by the body 3 and surrounding the processing cup 2 in the circumferential direction creates a noise barrier space outside the processing cup 2, which can reduce the outward transmission of noise generated during the operation of the food supplement machine and reduce the noise level of the whole machine during operation. At the same time, a lateral opening 316 is set on one side of the vertical wall 31 to ensure the visibility and ease of disassembly and assembly of the processing cup 2, and achieve a balance between sound insulation and operation performance.

[0036] (2) By forming a buffer gap 33 between the processing cup 2 and the C-shaped vertical wall 31, the vibration generated by the processing cup 2 during operation is buffered, reducing the direct transmission of vibration energy to the machine body 3, thereby reducing structural resonance noise; at the same time, the buffer gap 33 provides an air circulation channel, which helps to dissipate heat in the processing area and improves the stability and service life of the equipment.

[0037] (3) By adopting a double-layer hollow structure for the C-shaped vertical wall 31, and setting reinforcing ribs 317 on the outer wall 311 and / or the inner wall 312, the C-shaped vertical wall 31 has higher overall rigidity and vibration resistance. The double-layer hollow structure forms an air gap inside the C-shaped vertical wall 31 to attenuate noise transmission; the reinforcing ribs 317 form a longitudinal support frame in the hollow cavity, which can distribute the force and suppress structural deformation, thereby further reducing vibration and noise during operation and improving the structural stability and quiet performance of the baby food machine under long-term use.

[0038] (4) By abutting the lower end of the machine head 1 against the arc-shaped step surface 313, the machine head 1 is stably installed and positioned, avoiding direct contact between the machine head 1 and the processing cup 2, thereby preventing damage to the processing cup 2 and improving the overall stability and durability of the machine.

[0039] 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.
