Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine with good noise reduction effect. Background Art

[0002] With the development of society and the improvement of living standards, people's pursuit of dietary diversity and healthy diet is constantly increasing. Therefore, various industrial food processing machines are gradually miniaturized and enter thousands of households. For example, meat grinders not only meet people's needs for healthy diet and nutrition, but also greatly improve people's quality of life, and are therefore loved by people.

[0003] Existing food processing machines such as meat grinders include a cup body with a grinding chamber, a grinding device arranged in the grinding chamber, and a motor located below the cup body and driving the grinding device to rotate. When using the food processing machine, the user places the food into the grinding chamber, and the grinding device rotates at high speed driven by the motor to process the food. The food processing machine will generate a lot of noise when processing food, and the motor is one of the main sources of noise. In order to reduce the spread of noise, for example, Chinese utility model patent CN218606272U discloses a food processing machine, which is surrounded by a soundproof cover on the outside of the motor to reduce the noise generated by the motor.

[0004] However, the existing food processing machines, especially meat grinders, generally have poor crushing performance when cutting ingredients, especially when crushing vegetable leaves. Since the vegetable leaves are light, some of the vegetable leaves will adhere to the side or bottom of the cup body during the crushing process, and the crushing device is fixed in a horizontal position for rotation and cutting, and the vegetable leaves attached to the wall cannot be crushed, resulting in insufficient processing of the ingredients. In order to solve the above problems, some manufacturers will set a reciprocating mechanism in the main machine, and through the motion conversion of the reciprocating mechanism, the crushing device can reciprocate up and down. Although this scheme enables the crushing device to move up and down to achieve a larger range of cutting in the axial direction, the existing structure usually wraps the motor and the reciprocating mechanism, which makes the heat dissipation effect of the motor poor, especially for such food processing machines with a reciprocating mechanism, the heat generated by the reciprocating mechanism will be more than that of a general food processing machine. At the same time, the noise generated by the reciprocating mechanism during operation will also increase accordingly. Therefore, how to balance the heat dissipation of the drive components inside the main machine and reduce the noise transmission to the outside, especially to reduce the noise transmitted to the user operation side is a technical problem that needs to be solved. Utility Model Content

[0005] The purpose of the utility model is to provide a food processing machine with good noise reduction effect, so as to solve the problem of how to balance the heat dissipation of the internal drive components of the main machine and reduce the noise transmission to the outside while achieving a larger range of cutting of food in the axial direction of the existing food processing machine, especially reducing the noise transmitted to the user operation side, which is a technical problem to be solved.

[0006] To achieve the above-mentioned purpose, the utility model provides a food processing machine with good noise reduction effect, including a main machine, a cup body detachably arranged on the main machine, a driving mechanism arranged in the main machine, a reciprocating motion mechanism transmission-connected with the driving mechanism, and an output shaft. A soundproof cover is arranged in the main machine and is arranged outside the driving mechanism and the reciprocating motion mechanism. The main machine includes an operation interface for operation and a back side arranged opposite to the operation interface. The soundproof cover is provided with a noise reduction port facing the back side.

[0007] The present application sets a driving mechanism and a reciprocating motion mechanism in the main unit, so that when the user uses the food processor to process food, the driving mechanism drives the output shaft to rotate circumferentially, and the reciprocating motion mechanism drives the output shaft to reciprocate axially, thereby greatly increasing the axial cutting space of the mixing knife in the cup body, so that the mixing knife can cut more food, which helps to improve the uniformity and efficiency of cutting, and at the same time can increase the amount of food cut at a single time, meeting the user's usage needs.

[0008] In addition, a soundproof cover is provided inside the main machine, which covers the driving mechanism and the reciprocating mechanism, so that when the user uses the food processor to process food, the noise generated by the driving mechanism and the reciprocating mechanism can be reflected and reduced in the soundproof cover, thereby reducing the noise transmitted outward by the driving mechanism and the reciprocating mechanism, and improving the noise reduction effect of the whole machine. At the same time, the main machine includes an operation interface for operation and a back side arranged opposite to the operation interface. The soundproof cover is provided with a noise reduction port facing the back side. On the one hand, the setting of the noise reduction port allows the heat generated by the driving mechanism and the reciprocating mechanism during operation to be dissipated outward through the noise reduction port, effectively improving the heat dissipation effect, avoiding the situation where the heat is accumulated in the soundproof cover and the temperature rise of each component is obvious, causing the work to be unstable or even interrupted, and ensuring the working stability of each component; on the other hand, the noise generated by the driving mechanism and the reciprocating mechanism during operation passes through the noise reduction port after the noise reduction of the soundproof cover, thereby effectively reducing the noise transmitted from the side of the operation interface, that is, the side close to the user operation, effectively reducing the amount of noise heard by the user, and improving the user experience. Compared with the traditional method of fully wrapping the driving mechanism and the reciprocating motion mechanism, it helps to reduce the amount of mold release of the sound insulation cover, thereby reducing the production cost of the main machine. At the same time, other structural components can be flexibly arranged at the noise reduction port, which can improve the compactness of the internal structure of the main machine and reduce the space occupied by the entire machine.

[0009] In a preferred implementation of a food processor with good noise reduction effect, a side of the sound insulation cover close to the noise reduction port is in a contracted shape.

[0010] By setting the side of the sound insulation cover close to the noise reduction port to be contracted, the noise in the sound insulation cover can continuously hit the inner wall of the sound insulation cover when propagating toward the noise reduction port, thereby further weakening the noise energy in the sound insulation cover, so that the amount of noise transmitted through the noise port is further reduced, thereby improving the noise reduction effect.

[0011] In a preferred implementation of a food processor with good noise reduction effect, a corner is provided in the soundproof cover.

[0012] By providing a corner in the soundproof cover, the noise generated by the driving mechanism and the reciprocating motion mechanism during operation can be transmitted in the soundproof cover and violently collide when passing through the corner, thereby increasing the probability of the noise colliding with the inside of the soundproof cover, thereby further weakening the energy of the noise and helping to further improve the noise reduction effect.

[0013] In a preferred implementation of a food processor with good noise reduction effect, the sound insulation cover includes a flat plate arranged near an operating interface and arc-shaped plates arranged at both ends of the flat plate, a corner is formed between the arc-shaped plate and the flat plate, and a accommodating cavity for accommodating an operating panel is formed on one side of the flat plate near the operating interface.

[0014] By configuring the soundproof cover to include a flat plate disposed near the operation interface and curved plates disposed at both ends of the flat plate, a corner is formed between the curved plates, so that the noise in the soundproof cover can continuously collide when passing through the curved plates, and the noise emitted from the center to the soundproof cover can rebound toward the center, so that the noise can rebound more times, further reducing the noise volume and improving the noise reduction effect. At the same time, a receiving cavity for accommodating the operation panel is formed on one side of the flat plate near the operation interface, so that part of the noise propagating to the front side can be further reduced under the action of the receiving cavity and the operation panel, thereby further reducing the noise propagating outward and further improving the noise reduction effect.

[0015] In a preferred implementation of a food processing machine with good noise reduction effect, a circuit board is further provided in the main machine, and the circuit board is arranged on one side of the noise reduction port.

[0016] By arranging the circuit board on one side of the noise reduction port, on the one hand, the noise transmitted outward through the noise reduction port can directly hit the circuit board, so that the circuit board can further silence and reduce the noise, further improving the noise reduction effect; on the other hand, when the driving mechanism and the reciprocating motion mechanism are working, the airflow generated is discharged outward through the noise reduction port and can be directly blown to the circuit board, thereby cooling the circuit board, avoiding the situation where the temperature rise of the circuit board is obvious and causing serious aging of electrical components, which helps to extend the service life of the circuit board.

[0017] In a preferred implementation of a food processing machine with good noise reduction effect, the projection of the circuit board in the radial direction of the main machine falls into the noise reduction opening, and a noise reduction gap is provided between the noise reduction opening and the circuit board.

[0018] By making the projection of the circuit board in the radial direction of the host fall into the noise reduction port, the airflow from the noise reduction port can completely cool down the circuit board, thereby further improving the cooling effect of the circuit board. At the same time, a noise reduction gap is provided between the noise reduction port and the circuit board, so that the noise can be transmitted to the back through the noise reduction gap, thereby avoiding the situation where the circuit board completely blocks the noise reduction port and the noise cannot be transmitted to the back.

[0019] In a preferred implementation of a food processor with good noise reduction effect, the main unit includes an outer shell and a base connected to the bottom end of the outer shell, the top wall of the outer shell is provided with a drain port, the base is provided with a water outlet, a drain pipe connecting the drain port and the water outlet is provided in the main unit, and the drain pipe is connected to the sound insulation cover as a whole.

[0020] By providing a drain port on the top wall of the housing, a water outlet on the base, and a drain pipe connecting the drain port and the water outlet in the main unit, when the user cleans the main unit, the cleaning water on the top wall of the housing of the main unit can enter the drain pipe through the drain port and be discharged outward from the water outlet, thereby avoiding the accumulation of water stains on the top wall of the housing. In addition, the drain pipe is connected to the soundproof cover as a whole. On the one hand, the soundproof cover can limit the drain pipe, reduce the shaking of the drain pipe, and improve the stability of the drain pipe, thereby avoiding the displacement or even falling off of the drain pipe when the main unit falls to the ground or suffers a major impact, causing the cleaning water to be directly discharged into the main unit through the drain port. At the same time, the strength of the drain pipe is improved, thereby avoiding the large deformation or even cracking of the drain pipe when it is hit, causing the cleaning water to overflow from the drain pipe into the main unit, thereby ensuring the drainage function of the drain pipe, effectively avoiding the situation where water stains etc. enter the main unit and cause the electrical components in the main unit to be damaged by moisture, thereby improving the stability of the operation of the whole unit; on the other hand, the structure of the drain pipe and the soundproof cover is simplified, the compactness of the internal structure is improved, and the volume of the whole unit is reduced.

[0021] In a preferred implementation of a food processor with good noise reduction effect, the drain pipe is located inside the soundproof cover; or,

[0022] The drain pipe is located on the side of the soundproof cover away from the noise reduction opening.

[0023] By arranging the drain pipe inside the soundproof cover, the noise of water flowing in the drain pipe can be greatly reduced inside the soundproof cover when the water is discharged outward through the drain pipe, thereby avoiding the situation where the noise generated in the drain pipe is directly transmitted to the outside, which helps to further improve the noise reduction effect.

[0024] By arranging the drain pipe on the side of the sound insulation cover away from the noise reduction port, when the water is discharged outwardly, the noise generated in the drain pipe can be reduced at the outer shell of the sound insulation cover or the main unit before being discharged outwardly, thereby further reducing the propagation of noise to the outside.

[0025] In a preferred implementation of a food processor with good noise reduction effect, the main machine includes a shell and a base connected to the bottom end of the shell, and the soundproof cover extends downward from the top wall of the shell; or,

[0026] The soundproof cover includes a first cover body extending downward from the top wall of the shell and a second cover body extending upward from the base, the noise reduction port includes a first opening formed on the first cover body and opening downward and a second opening formed on the second cover body and opening upward, and the first opening and the second opening are plugged together to form the noise reduction port; or,

[0027] A soundproofing hood extends upward from the base.

[0028] By setting the sound insulation cover to extend downward from the top wall of the outer shell, so that the top of the tube cover completely wraps the driving mechanism and the reciprocating motion mechanism, it helps to further enhance the noise reduction effect of the driving mechanism and the reciprocating motion mechanism, avoid the noise from being directly transmitted outward from the top, and reduce the outward propagation of noise.

[0029] By configuring the sound insulation cover to include a first cover body extending downward from the top wall of the shell and a second cover body extending upward from the base, the noise reduction port includes a first opening formed on the first cover body and opening downward and a second opening formed on the second cover body and opening upward, the first opening is plugged into the second opening to form the noise reduction port, so that the noise generated by the driving mechanism and the reciprocating motion mechanism can only be transmitted outward through the noise reduction port, effectively avoiding the situation where the noise is transmitted from the top or bottom, so that the noise can be completely reduced through the sound insulation cover, further improving the noise reduction effect.

[0030] By setting the sound insulation cover to extend upward from the base, the overall structural strength of the base is greatly improved, so that when the host falls to the ground or suffers a major impact, the base can withstand a larger impact force to avoid damage, thereby further improving the structural stability of the host.

[0031] In a preferred implementation of a food processor with good noise reduction effect, the sound insulation cover includes a first cover body extending downward from the top wall of the outer shell and a second cover body extending upward from the base. The first cover body and the second cover body are plugged into each other to form the sound insulation cover, and the first cover body extends into the second cover body.

[0032] By setting the first cover body to extend into the second cover body, the first cover body and the second cover body are overlapped in the horizontal direction, so that the first cover body and the second cover body can achieve double noise reduction, and at the same time can avoid the noise from being transmitted outward from the gap between the first cover body and the second cover body, thereby further improving the noise reduction effect.

DETAILED DESCRIPTION

[0040] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0041] It should be noted that many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0042] like Figures 1 to 4As shown, the utility model provides a food processing machine with good noise reduction effect, including a main machine 1, a cup body 2 detachably arranged on the main machine 1, a driving mechanism 3 arranged in the main machine 1, a reciprocating motion mechanism 4 and an output shaft 5 transmission-connected with the driving mechanism 3, a sound insulation cover 8 arranged outside the driving mechanism 3 and the reciprocating motion mechanism 4 is arranged in the main machine 1, the main machine 1 includes an operation interface for operation and a back side arranged opposite to the operation interface, and the sound insulation cover 8 is provided with a noise reduction port 84 facing the back side.

[0043] The present application sets a driving mechanism 3 and a reciprocating motion mechanism 4 in the main unit 1, so that when the user uses the food processor to process food, the driving mechanism 3 drives the output shaft 5 to rotate circumferentially, and the reciprocating motion mechanism 4 drives the output shaft 5 to reciprocate axially, thereby greatly increasing the axial cutting space of the mixing knife in the cup body 2, so that the mixing knife can cut more food, which helps to improve the uniformity and efficiency of cutting, and at the same time can increase the amount of food cut at a single time to meet the user's usage needs.

[0044] In addition, a soundproof cover 8 is provided inside the main unit 1 and is arranged outside the driving mechanism 3 and the reciprocating motion mechanism 4, so that the noise generated by the driving mechanism 3 and the reciprocating motion mechanism 4 when the user uses the food processor to process food can be reflected and reduced in the soundproof cover 8, thereby reducing the noise propagated outward by the driving mechanism 3 and the reciprocating motion mechanism 4, thereby improving the noise reduction effect of the whole machine. At the same time, the host 1 includes an operation interface for operation and a back side arranged opposite to the operation interface. The soundproof cover 8 is provided with a noise reduction port 84 facing the back side. On the one hand, the setting of the noise reduction port 84 allows the heat generated by the driving mechanism 3 and the reciprocating mechanism 4 during operation to be dissipated outward through the noise reduction port 84, effectively improving the heat dissipation effect, avoiding the heat accumulation in the soundproof cover 8, which causes the temperature rise of each component to be significantly increased, causing the operation to be unstable or even interrupted, and ensuring the working stability of each component; on the other hand, the noise generated by the driving mechanism 3 and the reciprocating mechanism 4 during operation is reduced by the noise of the soundproof cover 8, and then passes through the back side of the entire host 1 through the noise reduction port 84, thereby effectively reducing the noise transmitted from the side of the operation interface, that is, the side close to the user operation, effectively reducing the amount of noise heard by the user, and improving the user experience. Compared with the traditional method of fully wrapping the driving mechanism 3 and the reciprocating mechanism 4, it helps to reduce the demoulding amount of the soundproof cover 8, thereby reducing the production cost of the host 1, and at the same time, other structural components can be flexibly arranged at the noise reduction port 84, which can improve the compactness of the internal structure of the host 1 and reduce the occupied space of the whole machine.

[0045] As a preferred embodiment of the present application, Figure 3 , Figure 4 As shown, the side of the sound insulation cover 8 close to the noise reduction opening 84 is in a contracted shape.

[0046] By setting the side of the sound insulation cover 8 close to the noise reduction port 84 to be in a contracted shape, the noise in the sound insulation cover 8 can continuously hit the inner wall of the sound insulation cover 8 when propagating toward the noise reduction port 84, thereby further weakening the noise energy in the sound insulation cover 8, so that the amount of noise transmitted through the noise port is further reduced, thereby improving the noise reduction effect.

[0047] As a preferred embodiment of the present application, Figure 3 As shown, a corner 83 is provided in the soundproof cover 8 .

[0048] By providing a corner 83 in the soundproof cover 8, the noise generated by the driving mechanism 3 and the reciprocating motion mechanism 4 during operation can be transmitted in the soundproof cover 8 and violently collide when passing through the corner 83, thereby increasing the probability of the noise colliding with the inside of the soundproof cover 8, thereby further weakening the energy of the noise and helping to further improve the noise reduction effect.

[0049] It should be noted that the present application does not specifically limit the forming of the corner 83. As a preferred embodiment of the present application, the sound insulation cover 8 includes a flat plate 81 arranged near the operating interface and arc-shaped plates 82 arranged at both ends of the flat plate 81. A corner 83 is formed between the arc-shaped plate 82 and the flat plate 81, and a accommodating cavity 13 for accommodating the operating panel 7 is formed on the side of the flat plate 81 near the operating interface.

[0050] By configuring the soundproof cover 8 to include a flat plate 81 disposed near the operation interface and curved plates 82 disposed at both ends of the flat plate 81, a corner 83 is formed between the curved plate 82 and the flat plate 81, so that the noise in the soundproof cover 8 can continuously collide when passing through the curved plate 82, and the noise emitted from the center to the soundproof cover 8 can rebound toward the center, so that the noise can rebound more times, further reducing the noise amount and improving the noise reduction effect. At the same time, a receiving cavity 13 for receiving the operation panel 7 is formed on one side of the flat plate 81 near the operation interface, so that part of the noise propagating to the front side can be further reduced under the action of the receiving cavity 13 and the operation panel 7, thereby further reducing the noise propagating outward and further improving the noise reduction effect.

[0051] As a preferred embodiment of the present application, Figure 3 As shown, a circuit board 6 is also disposed in the host 1 , and the circuit board 6 is disposed on one side of the noise reduction port 84 .

[0052] By arranging the circuit board 6 on one side of the noise reduction port 84, on the one hand, the noise transmitted outward through the noise reduction port 84 can directly hit the circuit board 6, so that the circuit board 6 can further silence and reduce the noise, further improving the noise reduction effect; on the other hand, when the driving mechanism 3 and the reciprocating motion mechanism 4 are working, the airflow generated is discharged outward through the noise reduction port 84, which can be directly blown to the circuit board 6, thereby cooling the circuit board 6, avoiding the situation where the temperature rise of the circuit board 6 is obvious and causes serious aging of electrical components, which helps to extend the service life of the circuit board 6.

[0053] Furthermore, if Figure 3 As shown, the projection of the circuit board 6 in the radial direction of the host 1 falls into the noise reduction opening 84 , and a noise reduction gap 841 is provided between the noise reduction opening 84 and the circuit board 6 .

[0054] By making the radial projection of the circuit board 6 on the host 1 fall into the noise reduction port 84, the airflow transmitted from the noise reduction port 84 can completely cool down the circuit board 6, thereby further improving the cooling effect of the circuit board 6. At the same time, a noise reduction gap 841 is provided between the noise reduction port 84 and the circuit board 6, so that the noise can be transmitted to the back through the noise reduction gap 841, thereby avoiding the situation where the circuit board 6 completely blocks the noise reduction port 84 and the noise cannot be transmitted to the back.

[0055] As a preferred embodiment of the present application, Figure 3 As shown, the host 1 includes a shell 11 and a base 12 connected to the bottom of the shell 11, the top wall of the shell 11 is provided with a drain port 111, the base 12 is provided with a water outlet, and a drain pipe 9 connecting the drain port 111 and the water outlet is provided in the host 1, and the drain pipe 9 is connected to the sound insulation cover 8 as a whole.

[0056] A drain port 111 is provided on the top wall of the outer shell 11, a water outlet is provided on the base 12, and a drain pipe 9 connecting the drain port 111 and the water outlet is provided in the host 1. When the user cleans the host 1, the cleaning water on the top wall of the outer shell 11 of the host 1 can enter the drain pipe 9 through the drain port 111 and be discharged outward from the water outlet, thereby avoiding the situation where water stains accumulate on the top wall of the outer shell 11. In addition, the drain pipe 9 is connected to the sound insulation cover 8 as a whole. On the one hand, the sound insulation cover 8 limits the drain pipe 9, reduces the shaking of the drain pipe 9, and improves the stability of the drain pipe 9, so as to prevent the drain pipe 9 from being displaced or even falling off when the main unit 1 falls to the ground or suffers a major impact, causing the cleaning water to be directly discharged into the main unit 1 through the drain port 111. At the same time, the strength of the drain pipe 9 is improved to prevent the drain pipe 9 from being greatly deformed or even cracked when it is hit, causing the cleaning water to overflow from the drain pipe 9 into the main unit 1, thereby ensuring the drainage function of the drain pipe 9, effectively preventing water stains from entering the main unit 1 and causing the electrical components in the main unit 1 to be damaged by moisture, thereby improving the stability of the whole machine operation; on the other hand, the structure of the drain pipe 9 and the sound insulation cover 8 is simplified, the compactness of the internal structure is improved, and the volume of the whole machine is reduced.

[0057] It should be noted that the present application only specifically limits the location of the drain pipe 9. As a preferred embodiment of the present application, Figure 3 As shown, the drain pipe 9 is located on the inner side of the sound insulation cover 8.

[0058] By arranging the drain pipe 9 on the inner side of the soundproof cover 8, the noise of water flow in the drain pipe 9 can be greatly reduced in the soundproof cover 8 when the water is discharged outward through the drain pipe 9, thereby avoiding the situation where the noise generated in the drain pipe 9 is directly transmitted to the outside, which helps to further improve the noise reduction effect.

[0059] As a preferred embodiment of the present application, Figure 3 As shown, the drain pipe 9 is located on a side of the sound insulation cover 8 away from the noise reduction opening 84 .

[0060] By arranging the drain pipe 9 on the side of the soundproof cover 8 away from the noise reduction port 84, when the drain pipe 9 is drained outward, the noise generated in the drain pipe 9 can be reduced at the soundproof cover 8 or the outer shell 11 of the main unit 1 before being discharged outward, thereby further reducing the propagation of noise to the outside.

[0061] It should be noted that the present application does not specifically limit the molding method of the sound insulation cover 8, which can be any one of the following embodiments:

[0062] Embodiment 1: In this embodiment, the host 1 includes a housing 11 and a base 12 connected to the bottom end of the housing 11 , and the soundproof cover 8 extends downward from the top wall of the housing 11 .

[0063] By setting the sound insulation cover 8 to extend downward from the top wall of the outer shell 11, the top of the tube cover completely wraps the driving mechanism 3 and the reciprocating mechanism 4, which helps to further enhance the noise reduction effect of the driving mechanism 3 and the reciprocating mechanism 4, avoids the noise from being directly transmitted outward from the top, and reduces the propagation of noise outward.

[0064] Example 2: Figure 3 As shown, in this embodiment, the sound insulation cover 8 includes a first cover body extending downward from the top wall of the outer shell 11 and a second cover body extending upward from the base 12, and the noise reduction port 84 includes a first opening formed on the first cover body and opening downward and a second opening formed on the second cover body and opening upward, and the first opening is plugged into the second opening to form the noise reduction port 84.

[0065] By configuring the sound insulation cover 8 to include a first cover body extending downward from the top wall of the outer shell 11 and a second cover body extending upward from the base 12, the noise reduction port 84 includes a first opening formed on the first cover body and opening downward and a second opening formed on the second cover body and opening upward, and the first opening is plugged into the second opening to form the noise reduction port 84, so that the noise generated by the driving mechanism 3 and the reciprocating motion mechanism 4 can only be transmitted outward through the noise reduction port 84, effectively avoiding the situation where the noise is transmitted from the top or bottom, so that the noise can be completely reduced through the sound insulation cover 8, further improving the noise reduction effect.

[0066] Furthermore, the first cover body extends into the second cover body.

[0067] By setting the first cover body to extend into the second cover body, the first cover body and the second cover body are overlapped in the horizontal direction, so that the first cover body and the second cover body can achieve double noise reduction, and at the same time can avoid the noise from being transmitted outward from the gap between the first cover body and the second cover body, thereby further improving the noise reduction effect.

[0068] Embodiment 3: In this embodiment, the soundproof cover 8 extends upward from the base 12.

[0069] By setting the sound insulation cover 8 to extend upward from the base 12, the overall structural strength of the base 12 is greatly improved, so that when the host 1 falls to the ground or suffers a severe impact, the base 12 can withstand a large impact force to avoid damage, thereby further improving the structural stability of the host 1.
