Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine capable of reciprocating motion. 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 disposed 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. However, existing food processing machines, especially meat grinders, generally have poor grinding performance when cutting food, especially when grinding 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 grinding process, and the grinding device is fixed in a horizontal position for rotation and cutting, and cannot grind the vegetable leaves that adhere to the wall, resulting in insufficient processing of the food. In order to solve the above problems, for example, Chinese invention patent CN107411525B discloses an automatically lifting and rotating cutting mixing knife, in which a reciprocating motion mechanism is arranged in the main machine. Through the motion conversion of the reciprocating motion mechanism, the crushing device can reciprocate up and down in a circular motion. Although this scheme enables the crushing device to move up and down to achieve a larger range of cutting in the axial direction, compared with the traditional meat grinder, a reciprocating motion mechanism is arranged in the main machine, so the structure in the main machine is relatively compact, especially the micro switch in the main machine that controls the on and off of the motor. The wires connected to the micro switch in the main machine are easily entangled in the fan or rotor driven by the motor, causing the motor and the micro switch to fail to work, and then causing the entire machine to fail to operate normally, seriously affecting the consumer experience. Utility Model Content

[0004] The utility model aims to provide a food processor capable of reciprocating motion, so as to solve the problem that the wire connected to the micro switch in the existing food processor is easily entangled on the motor, causing the micro switch and the motor to fail to work normally.

[0005] To achieve the above-mentioned purpose, the utility model provides a food processing machine with reciprocating motion, comprising a main machine, a detachable cup body arranged on the main machine, a driving mechanism arranged in the main machine, a reciprocating motion mechanism transmission-connected to the driving mechanism, and an output shaft, wherein the central axis of the driving mechanism is not colinear with the central axis of the reciprocating motion mechanism, and a micro switch for controlling the on and off of the driving mechanism is arranged in the main machine, and the micro switch is arranged on a side away from the driving mechanism.

[0006] The present application sets a driving mechanism and a reciprocating mechanism, 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 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 number of food cut in a single time, meeting the user's usage needs. At the same time, the central axis of the driving mechanism and the central axis of the reciprocating mechanism are not colinear, so that the driving mechanism can be placed sideways relative to the reciprocating mechanism, so that the driving mechanism and the reciprocating mechanism can overlap in the horizontal direction, thereby avoiding the situation where the two are located in the same axial position, resulting in a large axial space occupation, causing the axial size of the whole machine to be too long, and then causing the center of gravity of the whole machine to move upward and be unstable, which helps to improve the stability of the whole machine, and at the same time can expand the lateral size, so that the matching area between the bottom wall of the main machine and the desktop is increased, thereby further improving the stability of the whole machine.

[0007] In addition, a micro switch for controlling the on and off of the driving mechanism is provided in the main machine, so that when the user uses the food processor to process food, the cup body must be installed in place before the micro switch can be triggered and the motor can be operated, thereby ensuring the stability of food processing. At the same time, the micro switch is arranged on the side away from the driving mechanism. On the one hand, the wire connected to the micro switch can be away from the driving mechanism, especially the fan and other components driven by it, thereby effectively avoiding the wire being entangled on the rotor or fan of the driving mechanism when the driving mechanism rotates, causing the driving mechanism to be unable to continue to rotate and the micro switch to be unable to work, further improving the stability of the whole machine; on the other hand, the micro switch can be located in the space formed by the reciprocating motion mechanism away from the driving mechanism, effectively utilizing the space in the main machine, making the installation of various components more compact, helping to further reduce the space occupied by the main machine, and facilitating the storage of the whole machine by users.

[0008] In a preferred implementation of a reciprocating food processor, an angle A between a line connecting a central axis of the driving mechanism and a central axis of the reciprocating mechanism and a line connecting a central axis of the reciprocating mechanism and a central axis of the micro switch satisfies: 120°≤A≤180°.

[0009] By setting the angle A to satisfy: 120°≤A≤180°, it is avoided that the angle A is too low, resulting in the micro switch being too close to the drive mechanism, causing the wire connected to the micro switch to be easily entangled on the drive mechanism, further improving the protection of the micro switch and ensuring the stability of the drive mechanism.

[0010] In a preferred implementation of a reciprocating food processing machine, the main machine includes a casing, an operating interface is provided on the front side of the casing, a circuit board cooperating with the operating interface is provided inside the casing, and an angle B between a plane where the circuit board is located and a plane where the central axis of the driving mechanism and the central axis of the reciprocating mechanism are located satisfies: 0°≤B≤30°.

[0011] By providing an operation interface on the front side of the casing, the user can control the whole machine by controlling the operation interface when using the food processor to process food, which helps to improve the convenience of the user's control of the machine. At the same time, the angle B between the plane where the circuit board is located and the plane where the central axis of the drive mechanism and the central axis of the reciprocating mechanism are located is set to meet: 0°≤B≤30°, to avoid the angle between the plane where the circuit board is located and the plane where the central axis of the drive mechanism and the central axis of the reciprocating mechanism are located being too large, resulting in the end of the circuit board being too close to the drive mechanism, causing the wires connected to the circuit board to be easily entangled with the drive mechanism, causing the circuit board and the drive mechanism to fail to work, further improving the stability and reliability of the whole machine, and at the same time, it can also avoid the situation where the circuit board is too close to the drive mechanism and the reciprocating mechanism due to the large angle between the two, resulting in the circuit board being too close to the drive mechanism and the reciprocating mechanism, resulting in slow heat dissipation on the circuit board, causing its temperature rise to be obvious and its service life to be shortened.

[0012] In a preferred implementation of a reciprocating food processor, the plane where the circuit board is located is arranged parallel to the plane where the central axis of the driving mechanism and the central axis of the reciprocating mechanism are located.

[0013] By arranging the plane where the circuit board is located parallel to the plane where the central axis of the driving mechanism and the central axis of the reciprocating motion mechanism are located, the circuit board cannot touch the driving mechanism and the reciprocating motion mechanism, thereby further avoiding the situation where the wires are entangled on the driving mechanism. At the same time, it can ensure that there is a heat dissipation gap between the circuit board and the driving mechanism and the reciprocating motion mechanism, thereby improving the heat dissipation efficiency of the circuit board and helping to extend the service life of the circuit board.

[0014] In a preferred implementation of a reciprocating food processor, the micro switch is disposed on a side close to the circuit board, and the drive mechanism is disposed away from the circuit board.

[0015] By arranging the micro switch on the side close to the circuit board and the driving mechanism away from the circuit board, the distance between the micro switch and the circuit board is greatly shortened, thereby shortening the wires connecting the micro switch and the circuit board, which helps to further avoid the wires being entangled in the driving mechanism and further ensure the stability of the operation of the whole machine.

[0016] In a preferred implementation of a reciprocating food processor, a plurality of fixing positions fixed to the top wall of the main machine are provided on the outer periphery of the top of the reciprocating mechanism, and the plurality of fixing positions are arranged non-uniformly around the circumference formed by the central axis of the reciprocating mechanism; or,

[0017] The reciprocating motion mechanism includes a transmission part connected to the driving mechanism and a driving part arranged at one side of the transmission part and coaxially arranged with the output shaft, and the fixed position at one side of the driving part is not less than the fixed position at one side of the transmission part.

[0018] By providing a plurality of fixing positions fixed to the top wall of the main machine on the outer periphery of the top of the reciprocating mechanism, the main machine can limit and fix the reciprocating mechanism in multiple directions, thereby improving the stability of the connection between the reciprocating mechanism and the main machine, and avoiding the situation where the reciprocating mechanism is displaced or even separated from the main machine due to the unstable connection between the reciprocating mechanism and the main machine. At the same time, the plurality of fixing positions are arranged in an uneven distribution on the circumference formed by the central axis of the reciprocating mechanism, so as to limit the reciprocating mechanism at multiple positions in the circumferential direction, and further ensure the position stability of the reciprocating mechanism.

[0019] During operation, the driving part not only has to withstand the torque generated during transmission between the driving mechanism and the transmission part, but also has to withstand the supporting force generated during reciprocating motion of the output shaft. As the part that is subjected to greater force in the reciprocating motion mechanism, by making the fixing position on one side of the driving part no less than the fixing position on one side of the transmission part, the connection between one side of the driving part and the top wall of the main machine is made more stable, which helps to ensure the reliability of the position of the reciprocating motion mechanism and improve the transmission stability.

[0020] In a preferred implementation of a reciprocating food processor, a soundproof cover is provided in the main machine and is arranged outside the driving mechanism and the reciprocating mechanism, and the soundproof cover bulges outward along the lateral extension direction of the driving mechanism and the reciprocating mechanism.

[0021] By providing a soundproof cover in the main machine and covering the outside of the driving mechanism and the reciprocating mechanism, the noise generated by the driving mechanism and the reciprocating mechanism when the user uses the food processor to process food can be reflected and reduced in the soundproof cover, thereby reducing the noise propagated outward by the driving mechanism and the reciprocating mechanism, and improving the noise reduction effect of the whole machine. At the same time, the soundproof cover bulges outward along the lateral extension direction of the driving mechanism and the reciprocating mechanism, while ensuring that the soundproof cover can enclose the driving mechanism and the reciprocating mechanism, it can minimize the internal space occupied by the soundproof cover, which helps to further improve the compactness of the internal structure and reduce the space occupied by the main machine.

[0022] In a preferred implementation of a reciprocating food processor, the soundproof cover includes two flat plates arranged near the front and rear sides of the main machine and arc plates arranged at both ends of the two flat plates, and a corner is formed between the arc plates and the flat plates.

[0023] By configuring the sound insulation cover to include two flat plates arranged near the front and rear sides of the main unit and curved plates arranged at both ends of the two flat plates, and forming corners between the curved plates and the flat plates, the noise in the sound insulation cover can continuously collide when passing through the curved plates, and the noise emitted from the center to the sound insulation cover can rebound toward the center, so that the noise can rebound more times, further reducing the noise amount and improving the noise reduction effect.

[0024] In a preferred implementation of a reciprocating food processor, the micro switch is arranged outside the soundproof cover.

[0025] By arranging the micro switch outside the soundproof cover, the micro switch is isolated from the drive mechanism and the reciprocating motion mechanism, further avoiding the situation where the wires are entangled on the rotor or fan of the drive mechanism when the drive mechanism rotates, causing the drive mechanism to be unable to continue rotating and the micro switch to fail to work, thereby further improving the stability of the whole machine operation.

[0026] In a preferred implementation of a reciprocating food processing machine, the soundproof cover is also provided with a noise reduction port, and the driving mechanism is arranged on a side away from the noise reduction port.

[0027] By providing a noise reduction port in the soundproof cover, the heat generated by the driving mechanism and the reciprocating motion mechanism during operation can be dissipated outward through the noise reduction port, effectively improving the heat dissipation effect, avoiding the heat accumulation in the soundproof cover, causing the temperature rise of each component to be obvious, resulting in unstable operation or even interruption, and ensuring the working stability of each component. At the same time, the driving mechanism is arranged on the side away from the noise reduction port, so that the noise generated by the driving mechanism during operation can be fully reduced in the soundproof cover before being transmitted outward through the noise reduction port, which helps to further improve the noise reduction effect. And compared with the traditional method of fully wrapping the driving mechanism and the reciprocating motion mechanism, it helps to reduce the demolding amount of the soundproof 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 occupied space of the whole machine.

DETAILED DESCRIPTION

[0036] 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.

[0037] 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.

[0038] like Figures 1 to 5 As shown, the utility model provides a reciprocating food processing machine, comprising a main machine 1, a cup body 5 detachably arranged on the main machine 1, a driving mechanism 2 arranged in the main machine 1, a reciprocating mechanism 3 transmission-connected to the driving mechanism 2, and an output shaft 4, the central axis of the driving mechanism 2 is not colinear with the central axis of the reciprocating mechanism 3, a micro switch 6 for controlling the on and off of the driving mechanism 2 is arranged in the main machine 1, and the micro switch 6 is arranged on a side away from the driving mechanism 2.

[0039] The present application sets a driving mechanism 2 and a reciprocating mechanism 3, so that when the user uses the food processor to process food, the driving mechanism 2 drives the output shaft 4 to rotate circumferentially, and the reciprocating mechanism 3 drives the output shaft 4 to reciprocate axially, thereby greatly increasing the axial cutting space of the mixing knife in the cup body 5, 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 number of food cut in a single time, meeting the user's use needs. At the same time, the central axis of the driving mechanism 2 and the central axis of the reciprocating mechanism 3 are not colinear, so that the driving mechanism 2 can be placed sideways relative to the reciprocating mechanism 3, so that the driving mechanism 2 and the reciprocating mechanism 3 can overlap in the horizontal direction, thereby avoiding the situation that the two are located in the same axial position, resulting in a large axial space occupation, causing the axial size of the whole machine to be too long, and then causing the center of gravity of the whole machine to move upward and be unstable, which helps to improve the stability of the whole machine, and at the same time can expand the lateral size, so that the matching area between the bottom wall of the host 1 and the desktop is increased, thereby further improving the stability of the whole machine.

[0040] Specifically, Figure 5 As shown, the reciprocating mechanism 3 includes a first gear 32 and a second gear 33 sleeved on the outside of the output shaft 4, and the first gear 32 and the second gear 33 are respectively matched with the output shaft 4 for transmission. The driving mechanism 2 includes a motor, a motor shaft 21 provided on the motor, and a driving gear 22 provided at the output end of the motor shaft 21. The driving gear 22 is connected to the first gear 32 and the second gear 33 through an intermediate gear 9, and the upper part of the intermediate gear 9 is meshed with the first gear 32 and the second gear 33 for transmission, and the lower part of the intermediate gear 9 is meshed with the driving gear 22 for transmission.

[0041] In addition, a micro switch 6 for controlling the on and off of the drive mechanism 2 is provided in the main machine 1, so that when the user uses the food processor to process food, the cup body 5 must be installed in place before the micro switch 6 can be triggered and the motor can be operated, thereby ensuring the stability of food processing. At the same time, the micro switch 6 is arranged on the side away from the drive mechanism 2. On the one hand, the wire connected to the micro switch 6 can be away from the drive mechanism 2, especially the fan and other components driven by it, thereby effectively avoiding the situation where the wire is entangled on the rotor or fan of the drive mechanism 2 when the drive mechanism 2 rotates, causing the drive mechanism 2 to be unable to continue to rotate and the micro switch 6 to be unable to work, further improving the stability of the whole machine; on the other hand, the micro switch 6 can be located in the space formed by the reciprocating motion mechanism 3 away from the drive mechanism 2, effectively utilizing the space in the main machine 1, making the installation of each component more compact, helping to further reduce the occupied space of the main machine 1, and facilitating the storage of the whole machine by the user.

[0042] As a preferred embodiment of the present application, Figure 3 As shown, the angle A between the line connecting the central axis of the driving mechanism 2 and the central axis of the reciprocating mechanism 3 and the line connecting the central axis of the reciprocating mechanism 3 and the central axis of the micro switch 6 satisfies: 120°≤A≤180°, preferably, the angle A is equal to 160°, 170° or 180°.

[0043] By setting the angle A to satisfy: 120°≤A≤180°, it is avoided that the angle A is too low, resulting in the micro switch 6 being too close to the drive mechanism 2, causing the wire connected to the micro switch 6 to be easily entangled on the drive mechanism 2, thereby further improving the protection of the micro switch 6 and ensuring the stability of the operation of the drive mechanism 2.

[0044] As a preferred embodiment of the present application, the main unit 1 includes a casing, an operation interface is provided on the front side of the casing, a circuit board 7 cooperating with the operation interface is provided inside the casing, and an angle B between a plane where the circuit board 7 is located and a plane where the central axis of the driving mechanism 2 and the central axis of the reciprocating motion mechanism 3 are located satisfies: 0°≤B≤30°.

[0045] By providing an operation interface on the front side of the casing, the user can control the whole machine by controlling the operation interface when using the food processor to process food, which helps to improve the convenience of the user's control of the machine. At the same time, the angle B between the plane where the circuit board 7 is located and the plane where the central axis of the drive mechanism 2 and the central axis of the reciprocating mechanism 3 are located is set to meet: 0°≤B≤30°, so as to avoid the angle between the plane where the circuit board 7 is located and the plane where the central axis of the drive mechanism 2 and the central axis of the reciprocating mechanism 3 is too large, resulting in the end of the circuit board 7 being too close to the drive mechanism 2, causing the wire connected to the circuit board 7 to be easily entangled with the drive mechanism 2, causing the circuit board 7 and the drive mechanism 2 to fail to work, further improving the stability and reliability of the whole machine, and at the same time, it can also avoid the situation where the angle between the two is too large, resulting in the circuit board 7 being too close to the drive mechanism 2 and the reciprocating mechanism 3, resulting in the slow heat dissipation of the circuit board 7, causing its temperature rise to be obvious and the service life to be shortened.

[0046] Furthermore, if Figure 3 As shown, the plane where the circuit board 7 is located is arranged parallel to the plane where the central axis of the driving mechanism 2 and the central axis of the reciprocating motion mechanism 3 are located.

[0047] By arranging the plane where the circuit board 7 is located parallel to the plane where the central axis of the driving mechanism 2 and the central axis of the reciprocating motion mechanism 3 are located, the circuit board 7 cannot touch the driving mechanism 2 and the reciprocating motion mechanism 3, thereby further avoiding the situation where the wire is entangled on the driving mechanism 2. At the same time, it can also ensure that there is a heat dissipation gap between the circuit board 7 and the driving mechanism 2 and the reciprocating motion mechanism 3, thereby improving the heat dissipation efficiency of the circuit board 7, which helps to extend the service life of the circuit board 7.

[0048] As a preferred embodiment of this embodiment, Figure 3 As shown, the micro switch 6 is arranged on a side close to the circuit board 7, and the driving mechanism 2 is arranged away from the circuit board 7.

[0049] By arranging the micro switch 6 on a side close to the circuit board 7 and the driving mechanism 2 away from the circuit board 7, the distance between the micro switch 6 and the circuit board 7 is greatly shortened, thereby shortening the wire connecting the micro switch 6 and the circuit board 7, which helps to further avoid the wire being entangled in the driving mechanism 2, thereby further ensuring the stability of the operation of the whole machine.

[0050] As a preferred embodiment of the present application, Figure 3 As shown, a plurality of fixing positions 31 fixed to the top wall of the main machine 1 are provided on the outer periphery of the top end of the reciprocating motion mechanism 3 .

[0051] By providing a plurality of fixing positions 31 fixed to the top wall of the main machine 1 on the outer periphery of the top of the reciprocating mechanism 3, the main machine 1 can realize the limit fixing of the reciprocating mechanism 3 in multiple directions, thereby improving the stability of the connection between the reciprocating mechanism 3 and the main machine 1, and avoiding the situation where the reciprocating mechanism 3 is displaced or even separated from the main machine 1 due to the unstable connection between the reciprocating mechanism 3 and the main machine 1. Preferably, as Figure 3 As shown, the fixing position 31 is a lug extending outward from the outer periphery of the top end of the reciprocating motion mechanism 3, the lug is provided with a connecting notch, and a fixing hole axially aligned with the connecting notch is provided on the inner top wall of the main machine 1, and a connecting piece such as a screw passes through the connecting notch and is fastened to the fixing hole to realize the hoisting and fixing of the reciprocating motion mechanism 3.

[0052] It should be noted that the present application does not specifically limit the setting position of the fixing position 31. As a preferred embodiment of the present application, Figure 3 As shown, the plurality of fixing positions 31 are arranged in an uneven distribution along the circumference formed by the central axis of the reciprocating motion mechanism 3 .

[0053] By arranging the plurality of fixing positions 31 in an uneven distribution along the circumference formed by the central axis of the reciprocating mechanism 3 , the reciprocating mechanism 3 is limited at a plurality of positions in the circumferential direction, thereby further ensuring the position stability of the reciprocating mechanism 3 .

[0054] Furthermore, if Figure 3 As shown, the reciprocating motion mechanism 3 includes a transmission part connected to the driving mechanism 2 and a driving part arranged on one side of the transmission part and coaxially arranged with the output shaft 4. The fixing positions 31 on the driving part side are not less than the fixing positions 31 on the transmission part side. Preferably, the fixing positions 31 on the driving part side are more than the fixing positions 31 on the transmission part side.

[0055] During operation, the driving part not only has to withstand the torque during transmission between the driving mechanism 2 and the transmission part, but also has to withstand the supporting force of the output shaft 4 during reciprocating motion. As the part of the reciprocating mechanism 3 that is subjected to greater force, by making the fixing position 31 on one side of the driving part no less than the fixing position 31 on one side of the transmission part, the connection between one side of the driving part and the top wall of the main machine 1 is made more stable, which helps to ensure the reliability of the position of the reciprocating mechanism 3 and improve the transmission stability.

[0056] As a preferred embodiment of the present application, Figure 2 , Figure 3 As shown, a soundproof cover 8 is provided inside the main machine 1 and is arranged outside the driving mechanism 2 and the reciprocating mechanism 3 . The soundproof cover 8 bulges outward along the lateral extension direction of the driving mechanism 2 and the reciprocating mechanism 3 .

[0057] By providing a soundproof cover 8 in the main machine 1 and covering the outside of the driving mechanism 2 and the reciprocating mechanism 3, the noise generated by the driving mechanism 2 and the reciprocating mechanism 3 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 2 and the reciprocating mechanism 3, and improving the noise reduction effect of the whole machine. At the same time, the soundproof cover 8 bulges outward along the direction in which the driving mechanism 2 and the reciprocating mechanism 3 extend laterally, while ensuring that the soundproof cover 8 can enclose the driving mechanism 2 and the reciprocating mechanism 3, it can minimize the internal space occupied by the soundproof cover 8, which helps to further improve the compactness of the internal structure and reduce the space occupied by the main machine 1.

[0058] It should be noted that the present application does not specifically limit the structure of the soundproof cover 8. As a preferred embodiment of the present application, Figure 3 As shown, the soundproof cover 8 includes two flat plates 81 disposed near the front and rear sides of the host 1 and arc plates 82 disposed at both ends of the two flat plates 81 , and a corner 83 is formed between the arc plates 82 and the flat plates 81 .

[0059] By configuring the soundproof cover 8 to include two flat plates 81 disposed near the front and rear sides of the host 1 and curved plates 82 disposed at both ends of the two flat plates 81, and forming a corner 83 between the curved plates 82 and the flat plates 81, the noise in the soundproof cover 8 can continuously collide when passing through the curved plates 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. Preferably, the front side of the flat plate located on the front side of the host 1 is used to install the first circuit board, and the rear side of the flat plate located on the rear side of the host 1 is used to install the second circuit board, so that both circuit boards are isolated from the driving mechanism 2, effectively avoiding the entanglement of the wires, and further improving the stability of the whole machine operation.

[0060] As a preferred implementation of the present application, Figure 3 As shown, the micro switch 6 is arranged outside the sound insulation cover 8.

[0061] By arranging the micro switch 6 outside the sound insulation cover 8, the micro switch 6 is isolated from the drive mechanism 2 and the reciprocating motion mechanism 3, further avoiding the situation where the wires are entangled on the rotor or fan of the drive mechanism 2 when the drive mechanism 2 rotates, causing the drive mechanism 2 to be unable to continue rotating and the micro switch 6 to be unable to work, thereby further improving the stability of the whole machine operation.

[0062] As a preferred implementation of the present application, Figure 4 As shown, the soundproof cover 8 is also provided with a noise reduction port 84 , and the driving mechanism 2 is arranged on a side away from the noise reduction port 84 .

[0063] By providing a noise reduction port 84 in the soundproof cover 8, the heat generated by the driving mechanism 2 and the reciprocating mechanism 3 during operation can 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 obvious, resulting in unstable operation or even interruption, and ensuring the working stability of each component. At the same time, the driving mechanism 2 is arranged on the side away from the noise reduction port 84, so that the noise generated by the driving mechanism 2 during operation can be fully reduced in the soundproof cover 8 and then transmitted outward through the noise reduction port 84, which helps to further improve the noise reduction effect. And compared with the traditional method of fully wrapping the driving mechanism 2 and the reciprocating mechanism 3, it helps to reduce the demolding amount of the soundproof cover 8, thereby reducing the production cost of the main unit 1. 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 main unit 1 and reduce the occupied space of the whole machine.

[0064] Furthermore, if Figure 4 As shown, the noise reduction port 84 is arranged on the back side facing the host 1.

[0065] By arranging the noise reduction port 84 on the back side facing the main unit 1, the noise generated by the driving mechanism 2 and the reciprocating motion mechanism 3 during operation is reduced by the noise of the sound insulation cover 8 and then passes through the back side of the entire main unit 1 through the noise reduction port 84, thereby effectively reducing the noise transmitted from the side of the operating interface, i.e., the side close to the user's operation, effectively reducing the amount of noise heard by the user, and improving the user experience.

[0066] 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.
