Description

Technical Field

[0001] This invention belongs to the field of food processing technology, and in particular relates to a food processing machine. Background Technology

[0002] Food processors typically consist of a main unit and a mixing cup. The main unit contains a motor assembly that drives the grinding blades inside the mixing cup. The bottom of the mixing cup has an upper connector that connects to the grinding blades. The upper end of the main unit has a protruding lower connector that connects to the motor shaft of the motor assembly. The motor assembly is fixed inside the main unit. The main unit has a bracket for mounting the motor. Typically, the motor and bracket are fixed together by a hoisting mechanism. Specifically, the bottom of the bracket has screw posts, and the motor has lugs around it that are fixed to the screw posts by screws. This hoisting structure results in a mounting gap between the motor and the upper part of the main unit. The height of the main unit is at least the sum of the height of the motor assembly, the height of the upper and lower main unit housings, and the upper and lower mounting gaps between the motor assembly and the main unit housings. The height of the main unit must be greater than the height of the motor assembly. Furthermore, because the motor assembly is fixed inside the main unit, the heat generated by the motor assembly tends to accumulate inside and cannot be dissipated. The lower end of the motor assembly usually has a fan for cooling the motor assembly, and the bottom of the main unit has an air duct corresponding to the fan, further increasing the height of the main unit. Summary of the Invention

[0003] The purpose of this invention is to provide a food processing machine that reduces the height of the main unit by changing the installation structure of the motor and the main unit.

[0004] To solve the above-mentioned technical problems, the present invention provides a food processing machine, including a main unit and a stirring cup detachably mounted on the main unit. The stirring cup is provided with a pulverizing blade. The main unit is provided with a motor assembly for driving the pulverizing blade to rotate. The main unit includes a main unit housing, which forms a mounting cavity for mounting the motor assembly. The main unit housing has an opening communicating with the mounting cavity. At least a portion of the motor assembly forms the outer surface of the main unit together with the main unit housing through the opening.

[0005] This invention forms the outer surface of the main unit by having at least a portion of the motor assembly, through the opening, together with the main unit housing. The outer surface of the main unit is formed by the main unit housing and a portion of the motor assembly's surface. This design eliminates at least one installation gap between the motor assembly and the main unit, thereby reducing the main unit's height. Furthermore, it breaks the limitation of the main unit's height being solely determined by the motor's height, allowing the main unit to be no taller than the motor assembly. Specifically, by forming a portion of the main unit's outer surface with the exposed end face of the motor assembly, the main unit's height is less than the motor assembly's height. The exposed end face of the motor assembly also improves the motor's heat dissipation performance, ensuring adequate cooling even without the fan mounted on the lower end of the motor shaft. This further reduces the main unit's height, making it easier and less strenuous for users to pick up and place the mixing cup, reducing space occupation and improving the user experience. The opening can be located at the top, bottom, or side of the main unit, allowing for greater design freedom in the motor's position and installation method relative to the main unit. This effectively reduces the main unit's size while making the internal space more compact and efficient, resulting in higher space utilization. When the opening is located on the side of the main unit housing, it effectively reduces the main unit's length and width, facilitating easy handling and storage. In addition, this configuration results in a high degree of integration between the motor and the main unit. The motor and the main unit housing form a motor assembly, which can be used as an independent component to adapt to different cups or functional parts, thereby improving the versatility of the main unit and greatly improving the consistency and reliability of production and manufacturing. The miniaturized main unit provides convenience for the packaging and transportation of the whole machine, reduces packaging material loss and turnover space, and avoids product damage during transportation.

[0006] Furthermore, the opening is located on the upper and / or lower surface of the main unit housing, thereby exposing the upper and / or lower end faces of the motor assembly through the opening and forming the outer surface of the main unit together with the main unit housing, effectively reducing the overall height of the machine without affecting the processing capacity and high processing efficiency of the mixing cup.

[0007] Furthermore, the motor assembly includes a motor and a motor bracket disposed on the outside of the motor, with at least a portion of the motor bracket forming a part of the outer surface of the host through the opening. The motor includes a stator, a rotor, and a motor shaft. The motor bracket mounts the stator and rotor of the motor inside the motor bracket, thereby protecting the motor. Additionally, the motor bracket forms the upper and / or lower end faces of the motor assembly, which are exposed to the host through the opening, thus ensuring the flatness of the exposed end faces of the motor assembly.

[0008] Furthermore, the motor bracket passes through the opening and is flush with the upper or lower surface of the main unit housing. By setting the exposed end face of the motor bracket flush with the upper or lower surface of the main unit housing, the exposed end face of the motor assembly is formed as part of the outer surface of the main unit, making the main unit housing flatter.

[0009] Furthermore, the main unit housing includes an upper housing and a lower housing, which together form the mounting cavity. The upper housing and the lower housing clamp and fix the motor assembly in the mounting cavity, thereby eliminating the screw structure for mounting the motor. By clamping and fixing the motor assembly with the upper and lower housings, no installation gap is required, thus reducing the height of the main unit. Moreover, the clamping structure reduces the vibration of the main unit, playing a role in shock absorption and noise reduction.

[0010] In some embodiments, the upper housing has the opening, the motor assembly includes a motor and a motor bracket disposed on the upper end of the motor, the upper end face of the motor bracket is disposed in the opening, and the outer periphery of the motor bracket has an upper flange that abuts against the inner side of the upper housing. By setting the upper flange on the outer periphery of the motor bracket to abut against the inner side of the upper housing, relative to the upper end face of the motor assembly abutting against the inner side of the upper housing, it is convenient to adjust the height relationship between the upper end face of the motor assembly and the upper end face of the upper housing by adjusting the position of the upper flange. Moreover, when the upper flange is fixed to the upper housing, it does not increase the height of the main unit. In addition, the lower end face of the motor assembly can directly abut against the lower housing, simplifying the motor installation structure.

[0011] In some specific embodiments, the motor includes a motor shaft, and the upper end face of the motor bracket is provided with a clearance hole to avoid the motor shaft. Sealing structures are respectively provided between the motor bracket, the motor shaft, and the upper housing. By exposing the upper end face of the motor bracket to the main unit, the motor shaft only needs to pass through the upper end face of the motor bracket, without needing to pass through the upper end face of the main unit housing, thus improving the alignment of the motor shaft. Furthermore, the sealing structure between the motor bracket and the motor shaft prevents water from entering the motor, eliminating the need for an additional waterproof structure inside the motor, reducing the height of the motor, and consequently reducing the height of the main unit. Additionally, the sealing structure between the motor bracket and the upper housing prevents water from entering the upper surface of the main unit, ensuring the waterproofness of the mounting cavity.

[0012] In some embodiments, the lower housing has the opening, the motor assembly includes a motor and a motor bracket that covers the lower end of the motor, the lower end face of the motor bracket is located at the opening, and the outer periphery of the motor bracket has a downward flange that abuts against the inner side of the lower housing, so as to facilitate the adjustment of the height relationship between the lower end face of the motor assembly and the lower end face of the lower housing by adjusting the position of the downward flange. Moreover, the downward flange does not increase the height of the main unit when it is fixed to the lower housing. In addition, the upper end face of the motor assembly can directly abut against the upper housing, simplifying the installation structure of the motor.

[0013] In some embodiments, the upper and lower housings are respectively provided with the openings. The motor assembly includes a motor and a motor bracket disposed outside the motor. The motor bracket is elastically connected to the upper and lower housings respectively. The upper and lower end faces of the motor bracket are exposed to the host through the openings, ensuring that the height of the host is not greater than the height of the motor assembly. Moreover, the upper and lower end faces of the motor assembly are both exposed to the host, increasing the heat dissipation area of ​​the motor assembly and improving the heat dissipation performance of the motor. In addition, the motor assembly is elastically clamped between the upper and lower housings, reducing the vibration between the motor assembly and the host, and achieving a noise reduction effect.

[0014] In some specific embodiments, the motor bracket includes an upper bracket and a lower bracket with a gap between them. The upper and lower brackets are fixed to clamp the motor between them. The gap between the upper and lower brackets facilitates the release of heat from the motor, preventing the heat from being trapped inside the motor bracket. Furthermore, a fan can be installed inside the main unit, and the gap between the upper and lower brackets can form a heat dissipation channel for the motor, improving its heat dissipation performance. The motor is fixedly clamped between the upper and lower brackets, thereby reducing the installation gap between the motor and the motor bracket, lowering the height of the motor assembly, and facilitating the installation of the motor assembly while improving its reliability.

[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be arbitrarily combined with each other.

[0029] like Figures 1 to 10 As shown, the present invention provides a food processing machine, including a main unit 2 and a mixing cup 1 detachably mounted on the main unit. The mixing cup is provided with a pulverizing blade. The main unit 2 is provided with a motor assembly 3 for driving the pulverizing blade to rotate. The main unit is provided with a mounting cavity 22 for mounting the motor assembly. At least one of the upper or lower surfaces of the main unit is provided with an opening 213 communicating with the mounting cavity. The upper end face and / or lower end face of the motor assembly are exposed to the main unit through the opening. By exposing at least one end face of the upper or lower end face of the motor assembly to the main unit through the opening in the upper or lower surface of the main unit, the present invention eliminates at least one installation gap between the motor assembly and the main unit, thereby reducing the height of the main unit. In particular, by making the exposed end face of the motor assembly protrude from the surface of the main unit, the height of the main unit is less than the height of the motor assembly. Moreover, the exposed end face of the motor assembly improves the heat dissipation performance of the motor. Even if the fan installed at the lower end of the motor shaft is removed, a certain heat dissipation performance can still be guaranteed, further reducing the height of the main unit.

[0030] Example 1:

[0031] like Figures 1-6As shown, this invention provides a food processor, including a main unit 2 and a mixing cup 1 detachably mounted on the main unit 2. The mixing cup 1 contains a pulverizing blade for cutting food ingredients. The mixing cup 1 also contains a heating element. The main unit 2 has a coupler to power the heating element. The main unit 2 has a mounting cavity 22 for mounting a motor assembly. The motor assembly drives the pulverizing blade in the mixing cup 1 to rotate, thereby realizing the heating and pulverizing functions of the food processor. The blade shaft of the pulverizing blade and the motor shaft 311 in the motor assembly can be detachably connected via a connecting head or other transmission structure, or they can be directly connected through direct engagement. Specifically, both the upper and lower surfaces of the main unit 2 have openings 213 communicating with the mounting cavity to allow the motor assembly to... Both the upper and lower ends of motor assembly 3 are exposed to the host through openings 213. This invention exposes the upper and lower ends of motor assembly 3 to the host through openings 213 on the upper and lower surfaces of the host. The exposed ends of the motor assembly are non-metallic, and the connection between the non-metallic ends and the outer surface of the host is reliable and stable with good strength. While ensuring safe use, the fixing structure between the host 2 and motor assembly 3 is moved to the periphery of the motor assembly, eliminating the installation gap between the motor assembly 3 and the host in the longitudinal direction. This ensures that the height of the host is no higher than the height of the motor assembly, thereby achieving a flattened host. Moreover, the exposed ends of the motor assembly improve the heat dissipation performance of the motor, and a fan can be omitted below the motor assembly, further reducing the height of the host.

[0032] like Figures 1-3 As shown, the main unit includes a main unit housing 21, which includes an upper housing 211 and a lower housing 212. The upper and lower housings together form a mounting cavity 22. Both the upper and lower housings have openings 213 that communicate with the mounting cavity. The upper and lower end faces of the motor assembly are completely exposed to the main unit housing 21 through the openings, maximizing the heat dissipation area of ​​the motor assembly. Furthermore, the upper and lower end faces of the motor assembly are flush with the upper and lower end faces of the main unit housing 21 through the openings, thus making the exposed end faces of the motor assembly part of the outer surface of the main unit, resulting in a flatter main unit housing 21. Figure 2As shown, the upper surface of the upper outer shell has an upwardly protruding step 2111 with an opening on the upper surface of the step. The upper end face of the motor assembly 3 is flush with the upper surface of the step. In addition, one side of the upper outer shell has an upwardly protruding operating area 2112, which is flush with the upper surface of the step. Below the operating area 2112, there are control boards 23 and power boards 24 stacked longitudinally. A recess is formed between the step 2111 and the operating area 2112 to fit with the mixing cup, which facilitates the installation of the mixing cup. Moreover, by fitting with the mixing cup through the recess, there is no need to have multiple protrusions on the top of the main unit to install the mixing cup, as is the case with existing food processors. This further reduces the height of the main unit, making it more flat. In addition, the exposed end face of the motor is accommodated inside the cup holder, achieving a noise reduction effect. The height of the main unit 2 is H, which is 30mm≤H≤100mm, preferably 45mm≤H≤75mm. In this embodiment, H is 70mm, which realizes the true flatness of the whole machine, reduces the resonance space and vibration source. In addition, it not only greatly reduces the height of the whole machine, but also provides convenience for users to store it. Moreover, the weight of the whole machine is reduced, making it convenient and labor-saving to operate, and more convenient for women to use.

[0033] like Figure 2 , Figure 3 As shown, the upper outer shell 211 and the lower outer shell 212 clamp and fix the motor assembly 3 in the mounting cavity 22. Compared with suspending the motor assembly inside the main unit, the installation gap between the upper part of the motor assembly and the main unit is eliminated, thereby reducing the height of the main unit 2. In addition, the clamping method eliminates the stud structure for installing the motor assembly 3, simplifying the installation structure. Moreover, the clamping structure reduces the vibration of the main unit 2, playing a role in shock absorption and noise reduction.

[0034] like Figure 5 As shown, the motor assembly 3 includes a motor 31 and a motor bracket 32 ​​located on the outside of the motor. The motor bracket includes an upper bracket 321 and a lower bracket 322. The motor includes a stator, a rotor, and a motor shaft 311. The upper bracket is provided with a clearance hole 323 to avoid the motor shaft. The motor shaft only needs to pass through the upper end face of the motor bracket and does not need to pass through the upper end face of the main unit housing, which improves the alignment of the motor shaft. The upper bracket, the motor shaft, and the upper housing are respectively provided with sealing structures to prevent water from entering the upper surface of the main unit 2 and to ensure the waterproofness of the mounting cavity. There is no need to add a waterproof structure inside the motor, reducing the height of the motor and thus reducing the height of the main unit 2. The lower bracket 322 is the lower end that wraps around the motor. The motor bracket installs the stator and rotor of the motor inside the motor bracket, thereby protecting the motor. Furthermore, the upper and lower end faces of the motor assembly are formed by the motor bracket and exposed to the main unit 2 through the opening of the main unit 2, thereby ensuring the flatness of the exposed end face of the motor assembly 3.

[0035] like Figure 6As shown, the upper bracket 321 has an outwardly extending upper flange 2113 on its outer periphery, the height of which is lower than the upper end face of the upper bracket. The lower bracket 322 has an outwardly extending lower flange 2121 on its outer periphery, the height of which is higher than the lower end face of the lower bracket. During installation, as shown... Figure 2 As shown, the upper flange 2113 abuts against the inner side of the upper outer shell 211, and the lower flange 2121 abuts against the inner side of the lower outer shell 212. The end face of the motor assembly abuts against the inner side of the main unit shell, facilitating adjustment of the height relationship between the upper and lower end faces of the motor assembly and the upper and lower outer shells by adjusting the positions of the upper and lower flanges. Furthermore, fixing the motor assembly to the main unit shell using the upper and lower flanges does not increase the height of the main unit 2. Additionally, shock-absorbing pads 33 are provided between the upper outer shell and the upper bracket, and between the lower outer shell and the lower bracket, allowing the motor assembly to be elastically clamped between the upper and lower outer shells, reducing vibration between the motor assembly and the main unit 2, and achieving noise reduction. The motor assembly includes a motor and a motor bracket located at the upper end of the motor.

[0036] like Figure 2 , Figure 5 As shown, a gap is provided between the upper bracket 321 and the lower bracket 322. The upper and lower brackets are fixed to clamp the motor between them. Specifically, the upper and lower brackets can be fixed by fixing posts and screws, or by clips or other structures. The gap between the upper and lower brackets facilitates the release of heat from the motor, preventing the heat from being trapped inside the motor bracket. Furthermore, a fan can be installed inside the main unit 2, forming a heat dissipation channel for the motor through the gap between the upper bracket 321 and the lower bracket 322, improving the motor's heat dissipation performance. The motor is fixedly clamped between the upper and lower brackets via the upper bracket 321 and the lower bracket 322, thereby reducing the installation gap between the motor and the motor bracket, lowering the height of the motor assembly, and facilitating the installation of the motor assembly while improving its reliability. Figure 6 As shown, both the upper and lower brackets have support ribs facing the motor to position the motor. Furthermore, the lower bracket wraps around the lower end of the motor, and the positioning ribs of the lower bracket ensure that there is a gap between the lower end of the motor shaft and the lower bracket, so as to avoid interference between the motor shaft and the lower bracket or wear of the lower bracket when the motor shaft rotates.

[0037] like Figure 4 As shown, the lower end face of the motor bracket is provided with shock-absorbing pads 2122. The lower end face of the motor assembly is exposed to the main unit 2. By providing shock-absorbing pads on the exposed end face of the motor bracket, the motor assembly is made into elastic contact with the desktop, thereby reducing the vibration of the motor. Of course, the lower end face of the lower outer shell is also provided with shock-absorbing pads 2122, which together with the shock-absorbing pads on the lower end face of the motor bracket support the whole machine and place it stably.

[0038] Understandably, the base is equipped with an air duct, which surrounds the motor, thus reducing the overall height of the machine while improving the motor's heat dissipation and noise reduction.

[0039] Understandably, the upper surface of the motor assembly can be fitted with a heat insulation layer or a shock-absorbing pad.

[0040] Understandably, the upper and lower ends of the motor assembly can be partially exposed outside the main unit housing. The motor assembly and the main unit housing can use other fixing structures, as long as at least one end of the motor assembly is exposed outside the main unit housing.

[0041] Understandably, the operating area, control board, and power board can be installed in other locations on the main unit, and the operating area can be higher or lower than the upper surface of the motor assembly.

[0042] It is understandable that shock-absorbing feet can be installed only on the bottom of the main unit casing, and shock-absorbing feet can be omitted from the lower end of the motor bracket.

[0043] It's understandable that a mixing cup doesn't need a heating element.

[0044] Example 2:

[0045] The difference between this embodiment and Embodiment 1 is that the structure of the host casing is different.

[0046] In this embodiment, as Figure 7 As shown, the motor assembly 3 includes a motor 31, an upper bracket 321 covering the upper end of the motor, and a lower bracket 322 covering the lower end of the motor. The upper end face of the upper bracket forms the upper end face of the motor assembly, and the lower end face of the lower bracket forms the lower end face of the motor assembly. The main unit includes a main unit housing 21, which includes an upper housing 211 and a lower housing 212. The upper housing has an upwardly protruding stepped portion 2111. The stepped portion 2111 and the lower housing 212 respectively have openings that expose the upper end face of the upper bracket and the lower end face of the lower bracket to the main unit housing. The lower housing clamps and fixes the motor assembly inside the main unit. The upper end face of the upper bracket is exposed at the opening of the stepped part of the upper housing and is flush with the upper surface of the stepped part. The operating area 2112 is located on the upper surface of the upper housing and is lower than the upper surface of the stepped part. The upper housing 211 forms the upper surface of the main unit housing. The upper surface includes a flat base surface for mounting the operating area and an upwardly protruding stepped surface for clamping the upper end face of the motor assembly. This simplifies the upper surface structure of the main unit housing, making it easier to clean. Moreover, the lower layer of the operating area makes the main unit flatter and easier to operate.

[0047] like Figure 7As shown, the control board 23 is located below the operation area 2112. The power board and control board are changed from being stacked vertically to being arranged horizontally, so that the height of the operation area is only limited by the installation height of the control board, further reducing the height of the operation area. Specifically, the power board 24 is vertically installed inside the host, and the control board can be made into a narrow and long shape to reduce the height of the installation space and achieve the flattening of the host.

[0048] Understandably, the control board can be set in a ring or arc shape, and the control board can be installed horizontally around the motor.

[0049] Understandably, the control board can be divided into multiple smaller boards and installed inside the host to make full use of the internal space of the host, thereby achieving a flattened host design.

[0050] Example 3:

[0051] The difference between this embodiment and Embodiment 2 is that the installation structure of the motor assembly and the main unit is different.

[0052] In this embodiment, as Figure 8 As shown, the motor assembly 3 includes a motor 31, an upper bracket 321 covering the upper end of the motor, and a lower bracket 322 covering the lower end of the motor. The upper end face of the upper bracket 321 forms the upper end face of the motor assembly, and the upper end face is provided with a clearance hole 323 for avoiding the motor shaft. The lower end face of the lower bracket forms the lower end face of the motor assembly. The end faces of the upper bracket 321 and the lower bracket 322 are flat. The main unit includes a main unit housing 21, which includes an upper housing 211 and a lower housing 212. The upper housing is provided with an upwardly protruding stepped portion 211, and the center of the upper surface of the stepped portion is provided with a clearance hole 323 for avoiding the motor shaft. The lower outer casing has an opening 213 for the lower support to be exposed to the lower surface of the main unit casing and flush with the lower surface of the main unit casing. The step portion 2111 and the lower outer casing clamp and fix the motor assembly inside the main unit. Specifically, the upper surface of the motor upper support abuts against the inner side of the upper surface of the upper outer casing. The upper surface of the main unit casing wraps around the upper surface of the motor assembly to reduce the sealing position of the upper surface of the main unit casing, which not only improves the sealing performance of the main unit but also makes the upper surface of the main unit casing flatter. In addition, the motor is clamped by abutting, eliminating installation gaps and reducing the height of the main unit. The operating area is located on the upper surface of the upper outer casing and is lower than the upper surface of the step portion. The upper outer casing forms the upper surface of the main unit casing. The upper surface includes a flat base surface for mounting the operating area and an upwardly protruding step surface to clamp the upper surface of the motor assembly. This simplifies the upper surface structure of the main unit casing, making it easier to clean. The lower layer of the operating area makes the main unit flatter and easier to operate.

[0053] Understandably, the upper surface of the motor bracket can abut against the inner surface of the main unit's outer casing, or it can abut against a portion of the surface with protruding ribs.

[0054] Understandably, the upper surface of the motor bracket can directly abut against the inner surface of the main unit's outer casing, or it can indirectly abut against the main unit by setting a shock-absorbing structure between the two.

[0055] Understandably, the motor support can be a plate-like structure that wraps around the upper end of the motor, with only clearance holes for the motor, or it can partially wrap around the upper end of the motor, for example, by having an opening or being formed by multiple support plates extending axially.

[0056] Example 4:

[0057] The difference between this embodiment and Embodiment 3 is that the exposed end face of the motor assembly is different.

[0058] In this embodiment, as Figure 9 As shown, the motor assembly includes a motor 31, an upper bracket 321 that covers the upper end of the motor, and a lower bracket 322 that covers the lower end of the motor. The upper end face of the upper bracket forms the upper end face of the motor assembly, and the lower end face of the lower bracket forms the lower end face of the motor assembly. The main unit includes a main unit housing 21, which includes an upper housing 211 and a lower housing 212. The upper housing has an upwardly protruding step 2111 with an opening that exposes the upper end face of the upper bracket to the main unit housing. The lower end face of the lower bracket abuts against the upper surface of the lower housing. The motor assembly is clamped and fixed inside the main unit by the step and the lower housing. The lower end face of the main unit housing covers and supports the lower end face of the motor assembly. The entire motor assembly makes its installation more reliable and reduces the sealing positions on the lower end face of the main unit housing, improving the sealing performance of the main unit and making the lower surface of the main unit housing flatter. The opening of the upper end face of the upper bracket exposed on the stepped part of the upper housing is flush with the upper surface of the stepped part. The operating area is located on the upper surface of the upper housing and is lower than the upper surface of the stepped part. The upper housing forms the upper surface of the main unit housing. The upper surface includes a flat base surface for installing the operating area and an upwardly protruding stepped surface for clamping the upper end face of the motor assembly. This simplifies the upper surface structure of the main unit housing, making it easier to clean. Moreover, the lower layer of the operating area makes the main unit flatter and easier to operate.

[0059] Example 5:

[0060] The difference between this embodiment and embodiment four is that the mounting structure of the upper end of the motor assembly and the upper end of the main unit housing are different.

[0061] In this embodiment, as Figure 10As shown, the motor assembly includes a motor 31, an upper bracket 321 covering the upper end of the motor, and a lower bracket 322 covering the lower end of the motor. The lower bracket is abutted against the lower housing. The upper surface of the upper housing is flat and has no steps, while the upper surface of the upper bracket protrudes from the upper surface of the upper housing, effectively forming a step. The upper bracket includes an upper flange 2112, which is fastened to the upper housing. The upper surface of the upper bracket has a motor shaft clearance hole 323. This design further simplifies the installation and fixation between the upper bracket and the upper housing of the main unit, and also further simplifies the structure of the main housing, reducing manufacturing costs and assembly difficulty. Furthermore, the overall structure of the main unit is more integrated, and the exposed structure is simpler and easier to clean.

[0062] Example 6:

[0063] The difference between this embodiment and Embodiment 5 is that the location of the opening is different, and the structure of the motor assembly is different.

[0064] Specifically, in this embodiment, the motor assembly includes a motor, an upper bracket, and a lower bracket. The upper bracket abuts against the surface of the upper outer shell, and the lower bracket abuts against the surface of the lower outer shell. An opening is provided on the side wall of the main unit's outer shell, and a portion of the side wall of the motor assembly forms part of the side surface of the main unit. Specifically, the main unit's outer shell includes an upper outer shell and a lower outer shell. The upper outer shell has an upper opening, and the lower outer shell has a lower opening. The upper and lower openings together form the opening. The motor assembly also includes a motor housing that surrounds the outer periphery of the motor. The portion of the motor housing corresponding to the opening is exposed through the opening and forms part of the outer surface of the main unit. This design significantly reduces the size of the main unit, especially its length and width. While the height of the main unit is compressed to the extreme due to the flattened motor, the width and length are also simplified and miniaturized, resulting in a more rational and compact internal space, making it easier for users to pick up, place, and store.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes and modifications made in accordance with the present invention are covered by the scope of the claims of the present invention, and will not be listed here.
