Description

Technical Field:

[0001] The utility model relates to the technical field of noise reduction of household appliances, and particularly refers to a physical noise reduction structure of a wall breaker. Background Art:

[0002] Generally, a wall breaker includes accessories such as a high-speed motor, a cup body, and blades. Briefly speaking, the high-speed motor drives the blades to rotate to break the food in the cup body. Since the actual working speed of the high-speed motor is relatively high, between 16,000 and 30,000 revolutions per minute, the wall breaker will generate a large amount of noise during operation. If the noise is reduced by reducing the speed of the motor, the wall breaking time will be greatly increased, affecting the user experience. Therefore, the noise reduction function of the wall breaker is very important.

[0003] In recent years, the iterative direction of the wall breaker has mainly been to reduce noise and increase functions, developing from traditional wall breakers to silent wall breakers. However, most of them still mainly rely on passive noise reduction measures such as mechanical structure improvement and the use of sound insulation materials to reduce noise. But these measures have limited effects and often increase the volume and weight of the product.

[0004] Some wall breakers choose to cover another cover on the wall breaker to achieve physical sound filtering and noise reduction. For example, the Chinese invention patent application with the publication number of CN112617633A discloses a noise reduction and sound insulation cover for a wall breaker, which includes: a base, a sound insulation sleeve is fixedly arranged on the top of the base, a sound insulation cover is fixedly connected to the top of the sound insulation sleeve by clamping, a first handle is arranged at the center of the top of the sound insulation cover, a key operation window is arranged on the sound insulation sleeve at a position corresponding to the key area of the wall breaker, a window door is covered on the key operation window, magnetic attraction pieces are fixedly arranged around the bottom of the window door, and the magnetic attraction pieces are used in cooperation with magnetic attraction seats fixedly arranged around the inner wall of the key operation window. A second handle is arranged at the center of the outer wall of the window door. It can effectively reduce the noise during the operation of the wall breaker and avoid interfering with the environment.

[0005] However, this existing noise reduction and sound insulation cover for a wall breaker still has the following deficiencies:

[0006] In this technical solution, the base, the sound insulation sleeve, and the sound insulation cover are used together to separate the wall breaker from the surrounding environment to achieve the function of noise reduction. However, the sound insulation sleeve and the sound insulation cover need to completely accommodate the wall breaker inside, resulting in an overly large volume of the sound insulation cover. The shapes and sizes of various wall breakers are different. If the sound insulation sleeve and the sound insulation cover are blindly enlarged, the occupied space will be larger; in addition, the sound insulation cover and the wall breaker need to be operated separately, which not only increases the weight and volume of the whole machine, but also requires loading and unloading during each use, and the operation is extremely inconvenient, greatly affecting the user experience.

[0007] In view of this, the inventor of the present invention proposes the following technical solutions. Summary of the Utility Model:

[0008] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a noise reduction structure for a wall breaker.

[0009] To solve the above technical problems, the present utility model adopts the following technical solutions: A noise reduction structure for a wall breaker, comprising: a main body, inside which there is a motor; a wall breaker, which is detachably mounted on the main body, and within which there is a crushing space for accommodating food materials, and on which there is a handle part for a human hand to hold; a cover body, which is rotatably and unlockably arranged on the wall breaker; a knife set, which is arranged at the bottom of the crushing space and is used for breaking the food materials in the crushing space; a soft layer for reducing noise is arranged on the inner wall of the crushing space, and a sealing edge for sealing and noise reduction is arranged on the cover body.

[0010] Furthermore, in the above technical solution, the wall breaker comprises: a cup body in which the crushing space is formed, a housing sleeved around the outer periphery of the cup body, and a handle part mounted on the cup body. Among them, the soft layer is evenly distributed on the inner wall of the cup body to block the noise generated by the knife set within the crushing space, and a sound insulation gap for reducing noise is formed between the cup body and the housing.

[0011] Furthermore, in the above technical solution, the cover body comprises: an outer cover, a sound insulation middle cover fixedly integrated with the outer cover and capable of being inserted into the wall breaker, and a sealing edge sleeved on the sound insulation middle cover. Among them, a rotating handle for a human hand to rotate the cover body is formed on the outer cover, and a plug for rotationally locking or unlocking with the handle part is also formed on the rotating handle.

[0012] Furthermore, in the above technical solution, a locking groove for cooperating with the plug is opened at the upper end of the handle part, and a buckling part for buckling on the upper edge of the cup body is formed on the handle part.

[0013] Furthermore, in the above technical solution, a sound insulation space for reducing noise is formed between the outer cover and the sound insulation middle cover.

[0014] Furthermore, in the above technical solution, an adding hole for adding food materials is opened on the cover body. Correspondingly, a sealing plug is detachably arranged in the adding hole, and air holes for discharging steam and heat are opened on the sealing plug.

[0015] Furthermore, in the above technical solution, a docking protrusion is formed on the main body, and correspondingly, a docking groove is formed at the bottom of the wall breaker; a transmission component connected to the cutter group is arranged in the docking groove, and a driving part for matching with the transmission component is arranged at the output end of the motor. When the wall breaker is installed on the main body and the motor works, the driving part drives the cutter group to rotate at high speed through the transmission component.

[0016] Furthermore, in the above technical solution, the housing of the wall breaker is made of a sound-insulating material with high strength and low density.

[0017] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art: in the utility model, a soft layer is arranged on the inner wall of the crushing space by secondary molding, and a sealing edge is sleeved on the cover body to block the noise generated by the high-speed rotation of the cutter group in the crushing space, which can effectively reduce the noise defect, provide excellent noise reduction effect, and avoid using a sound-insulating cover on the wall breaker. It is not only more convenient to operate, but also effectively reduces the weight and volume of the whole machine. At the same time, the structure is simple and easy to implement, and will not excessively increase the volume and weight of the product. It is suitable for noise reduction treatment of various household appliances and has a wide application prospect. Description of the Drawings:

[0021] Figure 4 is a structural schematic diagram of the wall breaker in the utility model. Detailed Embodiments:

[0022] The following further describes the utility model with reference to specific embodiments and the drawings.

[0023] See Figures 1 to 4 As shown, it is a noise reduction structure of a wall breaker, which includes: a main body 1 with a motor 11 arranged inside; a wall breaker 2 detachably installed on the main body 1, with a crushing space 20 for accommodating food materials formed inside, and a handle part 21 fixed on the wall breaker 2 for human hands to hold; a cover body 3 rotatably and unlockably arranged on the wall breaker 2; a cutter group 4 arranged at the bottom of the crushing space 20 for breaking the food materials in the crushing space 20; a soft layer 5 for reducing noise arranged on the inner wall of the crushing space 20, and a sealing edge 31 for sealing and noise reduction arranged on the cover body 3.

[0024] In the present utility model, a soft layer 5 is provided on the inner wall of the crushing space 20. The soft layer 5 is formed on the inner wall of the crushing space 20 by double-color molding of a soft noise reduction material through a mold and then by secondary molding. In addition, a sealing edge 31 is sleeved on the cover body 3 to block the noise generated by the high-speed rotation of the cutter group 4 in the crushing space 20, which can effectively reduce the noise defect, provide an excellent noise reduction effect, and avoid using a sound insulation cover on the wall breaker. This not only makes the operation more convenient, but also effectively reduces the weight and volume of the whole machine. At the same time, the structure is simple and easy to implement, and will not excessively increase the volume and weight of the product. It is applicable to the noise reduction treatment of various household appliances and has a wide application prospect.

[0025] The wall breaker 2 includes: a cup body 29 forming a crushing space 20, a housing 22 sleeved outside the cup body 29, and a handle part 21 installed on the cup body 29. Among them, the soft layer 5 is evenly distributed on the inner wall of the cup body 29 to block the noise generated by the cutter group 4 in the crushing space 20, and a sound insulation gap 23 for reducing noise is formed between the cup body 29 and the housing 22. Here, the main noise of the wall breaker 2 is generated when the cutter group 4 in the crushing space 20 rotates at high speed. Therefore, setting the soft layer 5 for sound insulation on the inner wall of the crushing space 20 is the most direct and effective way, which can block the noise generated by the cutter group 4 in the crushing space 20 and achieve a good noise reduction effect; at the same time, a sound insulation gap 23 is also formed between the cup body 29 and the housing 22, that is, the noise weakened by the soft layer 5 is not directly transmitted to the outside world, but is further noise-reduced by the sound insulation gap 23. When it is transmitted to the outside world, it has been reduced to a range that will not affect human sleep (less than 50 dB).

[0026] Combined with Figure 3 As shown in the figure, the cover body 3 includes: an outer cover 32, a sound insulation middle cover 33 fixedly integrated with the outer cover 32 and capable of being inserted into the wall breaker 2, and a sealing edge 31 sleeved on the sound insulation middle cover 33. Among them, a rotating handle 321 for rotating the cover body 3 by a human hand is formed on the outer cover 32, and a plug pin 322 for rotationally locking or unlocking with the handle part 21 is also formed on the rotating handle 321. Here, when the cover body 3 is assembled, first, the sound insulation middle cover 33 of the cover body 3 is aligned with the cup mouth of the wall breaker 2. Further, the cover body 3 is pressed so that an interference fit is formed between the sealing edge 31 and the cup mouth of the wall breaker 2. Further, the cover body 33 is rotated so that the plug pin 322 on the rotating handle 321 is inserted into the upper end of the handle part 21 to achieve locking. The unlocking method is the same and will not be elaborated here.

[0027] The handle portion 21 has a locking groove 211 at its upper end for engaging with the latch 322. A latching portion 212 is formed on the handle portion 21 for latching onto the upper edge of the cup body 29. The locking groove 211 corresponds to the latch 322. When the cover 33 is rotated, the latch 322 engages with the locking groove 211 to secure the cover 3. This enhances the noise reduction and sealing effects of the cover 3 and prevents vibrations generated by the blade assembly 4 from affecting the cover 3.

[0028] A soundproof space 35 for reducing noise is formed between the outer cover 32 and the soundproof middle cover 33. Similar to the soundproof gap 23 of the wall-breaking machine 2, the cover 3 employs a soundproof space 35 to prevent the attenuated noise from being directly transmitted to the outside world, further reducing the noise. Furthermore, this embodiment can further include soundproofing pads within the soundproof space 35 and the soundproof gap 23 to further enhance noise isolation and overall sound insulation performance.

[0029] Combine Figure 2 and Figure 3 As shown, the lid 3 is provided with an addition hole 36 for adding ingredients. A corresponding sealing plug 361 is removably installed within the addition hole 36. This sealing plug 361 is provided with a vent hole 362 for venting steam and heat. The addition of the addition hole 36 allows smaller ingredients to be added directly to the wall-breaking machine 2 through the addition hole 36, eliminating the need to open the lid 3 each time, making it more convenient to use. Furthermore, the wall-breaking machine 2 generates heat during operation, particularly during the heating and stirring processes, which produce steam inside the machine. To ensure the safe operation and extend the life of the device, the provision of vent holes effectively dissipates heat and prevents damage from overheating. The vent holes 362 also facilitate steam release, preventing steam from accumulating inside the machine and thus protecting it from damage. Furthermore, the design of the vent holes 362 enhances the safety of the machine. For example, when the top lid is opened, the vent holes 362 allow steam to be quickly discharged, simultaneously stopping all mechanical rotation and heating processes, preventing burns to the user or other safety hazards.

[0030] A docking protrusion 101 is formed on the main unit 1, and correspondingly, a docking groove 201 is formed at the bottom of the wall breaker 2; a transmission component 202 that is transmission-connected to the knife group 4 is provided in the docking groove 201, and a driving part 102 for matching with the transmission component 202 is provided at the output end of the motor 11. When the wall breaker 2 is installed on the main unit 1 and the motor 11 is working, the driving part 102 drives the knife group 4 to rotate at high speed through the transmission component 202.

[0031] The housing 22 of the wall breaker 2 is made of a sound-insulating material with high strength and low density. Optionally, the outer shell of the wall breaker main body 1 can be set as a butyl damping rubber with high sound insulation performance, an integrated sound insulation board, etc., which can form a double-layer noise reduction with the soft layer 5 in the crushing space 20, greatly improving the noise reduction effect.

[0032] In summary, in the present utility model, a soft layer 5 is provided on the inner wall of the crushing space 20 by means of secondary molding, and a sealing edge 31 is sleeved on the cover body 3 to block the noise generated by the high-speed rotation of the cutter group 4 within the crushing space 20, which can effectively reduce the noise defect, provide an excellent noise reduction effect, and avoid using a sound insulation cover on the wall breaker. It is not only more convenient to operate, but also effectively reduces the weight and volume of the whole machine. At the same time, the structure is simple and easy to implement, without excessively increasing the volume and weight of the product. It is applicable to the noise reduction treatment of various household appliances and has a wide application prospect.

[0033] Of course, the above are only specific embodiments of the present utility model, and are not intended to limit the scope of implementation of the present utility model. Any equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present utility model shall be included in the scope of the patent application of the present utility model.
