Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processor with good splash-proof effect. Background Art

[0002] Existing food processors, such as meat grinders and noodle machines, typically consist of a cup with a built-in mixing blade and a removable main unit mounted above the cup. The main unit houses a motor that is connected to the mixing blade. When using the food processor, the user places ingredients in the cup, and the mixing blade, driven by the motor, rotates at high speed to process the ingredients. To ensure torque transmission between the motor's output and the mixing blade, a clearance hole is typically provided in the cup lid to allow the mixing blade to connect to the motor's output. However, the high-speed rotation of the mixing blade causes ingredients to splatter, some of which can splash through the clearance hole onto the main unit, making it difficult to clean and producing odors over time. Furthermore, splashing ingredients containing a high amount of water can enter the main unit, damaging the motor and shortening its service life. To solve this problem, some manufacturers will install an annular baffle on the blade shaft of the mixing blade to cover the avoidance opening and prevent food from splashing outwards. However, since the distance between the baffle and the blade is small and the lower end surface of the baffle is stained with food, users need to reach between the baffle and the blade to clean it, which poses a risk of cutting their hands.

[0003] In order to facilitate users to clean the baffle, some manufacturers set the baffle to be detachably connected to the knife shaft, and the user can remove the baffle for cleaning. The baffle includes a sleeve mounted on the knife shaft and a baffle arranged on the outside of the sleeve. When the user installs the baffle on the knife shaft, the sleeve is mounted on the outside of the knife shaft, and the top wall of the sleeve is provided with a circle of ribs extending inward, and the ribs abut the top surface of the knife shaft to achieve axial limitation. Since the wall thickness of the ribs is thin and easy to deform, in the actual assembly process, overpressure will occur when the user presses down on the baffle, causing the ribs to move directly downward to the knife shaft, making it very difficult for the user to pull it up, and the assembly process experience is poor, which seriously affects the consumer experience. Utility Model Content

[0004] The purpose of the utility model is to provide a food processor with good splash-proof effect, so as to solve the problem of overpressure in the process of disassembling and assembling the baffle while enhancing the cleaning safety of the mixing blade in the existing food processor.

[0005] To achieve the above-mentioned purpose, the utility model provides a food processor with good splash-proof effect, comprising a cup body with a built-in stirring knife and a detachable main unit arranged above the cup body, a motor connected to the stirring knife for transmission is provided in the main unit, the stirring knife comprises a knife shaft and a detachable baffle arranged on the knife shaft, the baffle comprises a sleeve arranged on the knife shaft and an annular baffle extending laterally outward from the sleeve, a limiting portion with a limiting surface facing upward is provided on the top of the knife shaft, the bottom wall of the sleeve abuts against the limiting surface, and the thickness of the sleeve is not less than the thickness of the annular baffle.

[0006] The present application provides a detachable baffle on the blade shaft, so that when the food processor is processing food, when the mixing blade is crushing the food at high speed, the food that splashes upwards can be prevented from continuing to move upwards by the baffle, thereby effectively preventing food from splashing onto the connection head between the motor and the blade shaft and the bottom wall of the main unit, ensuring the cleanliness of the entire machine and facilitating cleaning by the user. At the same time, the baffle is detachable from the blade shaft. Compared with existing mixing blades that are not detachable and are close to the blade, the user can remove the baffle to achieve a deep cleaning of the mixing blade when cleaning it, effectively avoiding the situation where the lower surface of the baffle is contaminated with food, causing the user to reach between the blade and the baffle to clean it, which may cause the user to cut his hand, thereby improving the user experience. In addition, a limiting portion with an upward limiting surface is provided on the top of the blade shaft, and the bottom wall of the sleeve abuts against the limiting surface, so that when the user assembles the baffle and the blade shaft, the baffle can be assembled when the bottom wall of the sleeve abuts against the limiting surface. At the same time, the thickness of the sleeve is not less than the thickness of the annular baffle, which greatly increases the thickness of the sleeve. When the user presses the sleeve downward to assemble the baffle, the bottom wall of the sleeve abuts against the limiting surface, and the entire sleeve realizes axial support for the baffle. Compared with the axial support of the baffle achieved by only a circle of thinner ribs, the sleeve has less deformation due to its thicker thickness, thereby avoiding the user pressing down too much, causing the sleeve to deform and slide down to the blade shaft below, and then causing greater resistance when the user pulls up to remove the baffle, thereby improving the user's disassembly and assembly experience.

[0007] In a preferred implementation of a food processor with good splash-proof effect, the limiting portion includes a limiting shaft arranged above the limiting surface, and the shaft sleeve interference sleeve is arranged outside the limiting shaft.

[0008] By configuring the limiting portion to include a limiting shaft provided above the limiting surface, and the shaft sleeve interference sleeve provided on the outside of the limiting shaft, the shaft sleeve can enhance the cooperation strength of the two through the interference fit with the limiting shaft, thereby enhancing the friction of the cooperation between the two, so as to ensure the stability of the connection between the shaft sleeve and the limiting shaft, and avoid the situation in which the food moves upward due to beating and squeezes and collides with the annular baffle, causing the baffle to be displaced or even separated from the knife shaft during food processing, especially when the mixing knife is kneading dough, the dough will gradually be kneaded to form dough in the later stage of food processing, and the dough has a greater upward force driven by the mixing knife. The interference fit of the shaft sleeve and the limiting column is used to ensure the position stability of the baffle, thereby ensuring the baffle's blocking effect on the food.

[0009] In a preferred implementation of a food processor with good splash-proof effect, the mixing knife also includes a blade, the knife shaft includes a first shaft section for installing the blade, and a second shaft section arranged above the first shaft section and radially reduced relative to the first shaft section, and the second shaft section is a limiting shaft.

[0010] By setting the cutter shaft to include a first shaft section for installing a blade, and a second shaft section arranged above the first shaft section and radially reduced relative to the first shaft section, and the second shaft section being a limiting shaft, the limiting shaft is directly formed on the cutter shaft, so that the cutter shaft can not only achieve fixed installation of the blade, but also achieve limited fixation of the baffle, thereby improving the function of the cutter shaft.

[0011] In a preferred implementation of a food processor with good splash-proof effect, a transmission shaft extending toward the motor and engaging with the output end of the motor is further provided on the top of the cutter shaft. The top surface of the cutter shaft forms a limiting surface, and the exposed portion of the transmission shaft after engaging with the output end of the motor forms a limiting shaft.

[0012] By forming the top surface of the cutter shaft into a limiting surface, and the exposed part of the transmission shaft after engaging with the output end of the motor into a limiting shaft, the forming of the limiting surface is simplified. At the same time, the transmission shaft can realize the limiting fixation of the baffle while realizing the torque transmission between the motor and the cutter shaft, and the function is more diverse. In addition, the outer surface of the transmission shaft is provided with multiple vertically extending limiting ribs, and there is no need to set additional interference ribs, which helps to simplify the structure of the transmission shaft, facilitate its production and reduce production costs.

[0013] In a preferred implementation of a food processor with good splash-proof effect, the limiting shaft also includes a mating surface located above the limiting surface and arranged opposite to the limiting surface. The mating surface, the side wall of the limiting shaft and the limiting surface form a limiting groove to clamp the sleeve.

[0014] By forming a limiting groove to clamp the shaft sleeve through the mating surface, the side wall of the limiting shaft and the limiting surface, the shaft sleeve can not only achieve the limitation of the two through interference fit after being sleeved on the limiting shaft, but also further achieve axial limitation and fixation of the shaft sleeve through the limiting groove, further avoiding the situation where the food collides with the annular baffle during food processing and causes the baffle to move up and down, and further improving the reliability of the cooperation between the baffle and the limiting shaft.

[0015] In a preferred implementation of a food processor with good splash-proof effect, the thickness of the shaft sleeve L1 and the thickness of the annular baffle L2 satisfy: 1 / 3≤L2 / L1≤2 / 3.

[0016] By satisfying the following conditions for the thickness of the sleeve L1 and the thickness of the annular baffle L2: 1 / 3≤L2 / L1≤2 / 3, the situation in which the sleeve is thinner than the annular baffle, which causes the sleeve to be easily deformed when the user presses down on the sleeve, causing the sleeve to be pressed below the limit surface, thereby making it difficult for the user to pull it out, can be avoided. At the same time, the situation in which the sleeve is thicker than the annular baffle, which causes the sleeve to be difficult to deform when the user presses down on the knife shaft, thereby making it difficult to press down, can be avoided. While ensuring that the baffle and the knife shaft are easily assembled, the situation in which the sleeve is easily deformed and over-assembled can be avoided.

[0017] In a preferred implementation of a food processor with good splash-proof effect, the annular baffle is a flexible member, and the thickness of the outer end of the annular baffle is smaller than the thickness of the side close to the shaft sleeve.

[0018] By setting the annular baffle as a flexible part, during the food processing process, part of the food moves upward and is squeezed onto the annular baffle under the stirring action of the mixing blade. With the help of the flexibility of the annular baffle, it can undergo a certain deformation, effectively avoiding the situation where the annular baffle is a rigid part and is broken when it is squeezed. At the same time, the thickness of the outer end of the annular baffle is less than the thickness of the side close to the shaft sleeve, which not only ensures the stability of the connection between the annular baffle and the shaft sleeve, but also avoids the situation where the connection between the annular baffle and the shaft sleeve is thin and easy to break. At the same time, when the side away from the shaft sleeve is deformed upward, it can cover the avoidance opening on the cup lid, thereby further avoiding the situation where food overflows.

[0019] In a preferred implementation of a food processor with good splash-proof effect, the mixing knife further includes a blade provided on the knife shaft, and the blade diameter D1 and the annular baffle diameter D2 satisfy: 1 / 5≤D2 / D1≤1 / 3.

[0020] By setting the blade diameter D1 and the annular baffle diameter D2 to satisfy: 1 / 5≤D2 / D1≤1 / 3, the annular baffle can press down on the food during food processing and achieve sufficient whipping under the action of the blade below, which helps to improve the processing effect of the food and avoids the situation where the annular baffle diameter is smaller than the blade diameter, resulting in poor downward pressure on the food.

[0021] In a preferred implementation of a food processor with good splash-proof effect, the food processor further comprises a cup cover provided on the cup body, the cup cover being provided with an escape opening for the knife shaft and the motor to cooperate with each other, and the escape opening radius R1 and the annular baffle radius R2 satisfy: 0≤R1-R2≤10mm; or,

[0022] The stirring blade further comprises a plurality of blades arranged on the blade shaft, and the distance between the top end of the blade and the top wall L3 of the annular baffle satisfies the following: 5mm≤L3≤10mm.

[0023] By setting the avoidance opening radius R1 and the annular baffle radius R2 to satisfy: 0≤R1-R2≤10mm, the situation where the annular baffle radius is smaller than the avoidance opening radius, causing food to splash outward through the gap between the annular baffle and the avoidance opening, is avoided; at the same time, the situation where the annular baffle radius is too large compared to the avoidance opening radius, causing the annular baffle to be easily deformed and its shielding failure is avoided.

[0024] By setting the distance L3 between the top end of the blade and the top wall of the annular baffle to satisfy: 5mm≤L3≤10mm, it is avoided that the top end of the blade is too close to the top wall of the annular baffle, which causes the food to splash out directly from the gap between the upper end surface of the annular baffle and the cup lid when it is crushed; at the same time, it is avoided that the top end of the blade is too far from the top wall of the annular baffle, which causes the annular baffle to have poor downward pressure on the food, resulting in poor food processing effect.

DETAILED DESCRIPTION

[0035] 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.

[0036] It should be noted that many specific details are set forth 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 scope of protection of the present invention is not limited to the specific implementation methods disclosed below.

[0037] like Figures 1 to 6 As shown, the utility model provides a food processor with good splash-proof effect, comprising a cup body 3 with a built-in stirring blade 4 and a main unit 1 detachably arranged above the cup body 3, wherein a motor 2 is provided in the main unit 1 and is transmission-connected to the stirring blade 4, the stirring blade 4 comprises a blade shaft 41 and a detachable baffle 42 arranged on the blade shaft 41, the baffle 42 comprises a sleeve 422 sleeved on the blade shaft 41 and an annular baffle 421 extending laterally outward from the sleeve 422, a limiting portion 44 with an upward limiting surface 441 is provided on the top of the blade shaft 41, the bottom wall of the sleeve 422 abuts against the limiting surface 441, and the thickness of the sleeve 422 is not less than the thickness of the annular baffle 421.

[0038] The present application provides a detachable baffle 42 on the blade shaft 41, so that when the food processor is processing food, when the mixing blade 4 is crushing the food at high speed, the food splashing upwards can be prevented from continuing to move upwards by the baffle 42, thereby effectively preventing food from splashing onto the connection head between the motor 2 and the blade shaft 41 and the bottom wall of the main unit 1, ensuring the cleanliness of the entire machine and facilitating cleaning by the user. At the same time, the baffle 42 is detachable relative to the blade shaft 41. Compared with the existing mixing blade 4 that is not detachable and is close to the blade, the user can remove the baffle 42 to achieve a deep cleaning of the mixing blade 4 when cleaning it, effectively avoiding the situation where the lower surface of the baffle 42 is contaminated with food, causing the user to reach between the blade and the baffle 42 to clean it, which may cause the user to cut his hand, thereby improving the user experience. The top of the blade shaft 41 is provided with a limiting portion 44 with a limiting surface 441 facing upwards, and the bottom wall of the sleeve 422 abuts against the limiting surface 441, so that when the user assembles the baffle 42 and the blade shaft 41, the bottom wall of the sleeve 422 abuts against the limiting surface 441, and the baffle 42 can be assembled. At the same time, the thickness of the sleeve 422 is not less than the thickness of the annular baffle 421, so that the thickness of the sleeve 422 is greatly increased. When the user presses the sleeve 422 downward to assemble the baffle 42, The bottom wall of the sleeve 422 abuts against the limiting surface 441, and the entire sleeve 422 provides axial support for the baffle 42. Compared with only a circle of thin ribs to provide axial support for the baffle 42, the sleeve 422 has less deformation due to its thicker thickness, thereby preventing the user from pressing down too much and causing the sleeve 422 to deform and slide down onto the knife shaft 41 below, thereby causing greater resistance when the user pulls up to remove the baffle 42, thereby improving the user's disassembly and assembly experience.

[0039] As a preferred embodiment of the present application, Figure 2 、 Figure 3 As shown, the limiting portion 44 includes a limiting shaft 442 disposed above the limiting surface 441 , and the shaft sleeve 422 is interference-fittedly disposed on the outside of the limiting shaft 442 .

[0040] By configuring the limiting portion 44 to include a limiting shaft 442 provided above the limiting surface 441, and the sleeve 422 being interference-fitted on the outside of the limiting shaft 442, the sleeve 422 can enhance the cooperation strength of the two through the interference fit with the limiting shaft 442, thereby enhancing the friction force of the cooperation between the two, thereby ensuring the stability of the connection between the sleeve 422 and the limiting shaft 442, and avoiding the situation in which the food is processed, the food moves upward due to beating and squeezes and collides with the annular baffle 421, causing the baffle 42 to be displaced or even separated from the knife shaft 41, especially when the mixing knife 4 is kneading the dough, in the later stage of food processing, the dough will gradually be kneaded to form dough, and the dough is driven by the mixing knife 4 with a large upward force. The interference fit between the sleeve 422 and the limiting shaft 442 ensures the position stability of the baffle 42, thereby ensuring the blocking effect of the baffle 42 on the food.

[0041] It should be noted that the present application does not specifically limit the shaping of the limiting shaft 442, which may be any one of the following embodiments:

[0042] Example 1: Figure 3 As shown, in this embodiment, the mixing knife 4 also includes a blade 43, the knife shaft 41 includes a first shaft section for installing the blade 43, and a second shaft section arranged above the first shaft section and radially reduced relative to the first shaft section, and the second shaft section is a limiting shaft 442.

[0043] By setting the cutter shaft 41 to include a first shaft section for installing the blade 43, and a second shaft section arranged above the first shaft section and radially reduced relative to the first shaft section, and the second shaft section is a limiting shaft 442, the limiting shaft 442 is directly formed on the cutter shaft 41, so that the cutter shaft 41 can not only achieve fixed installation of the blade 43, but also achieve limited fixation of the baffle 42, thereby improving the function of the cutter shaft 41.

[0044] It should be further explained that, in this embodiment, the connection method between the blade shaft 41 and the output end of the motor 2 is not specifically limited. Figure 3 As shown, it can be that a mounting groove is set on the inner side of the limiting shaft 442, a transmission shaft is fixed in the mounting groove, and the top of the transmission shaft engages with the output end of the motor 2 to realize torque transmission; of course, it can also be that a transmission shaft is formed above the limiting shaft 442 and extends upward, and the transmission shaft engages with the output end of the motor 2, which will not be repeated here.

[0045] Example 2: Figure 6 As shown, in this embodiment, a transmission shaft 6 extending toward the motor 2 and engaging with the output end of the motor 2 is further provided on the top of the knife shaft 41. The top surface of the knife shaft 41 forms a limiting surface 441, and the exposed part of the transmission shaft 6 after engaging with the output end of the motor 2 forms a limiting shaft 442.

[0046] By forming a limiting surface 441 on the top surface of the cutter shaft 41, and forming a limiting shaft 442 on the exposed part of the transmission shaft 6 after the transmission engagement with the output end of the motor 2, the forming of the limiting surface 441 is simplified. At the same time, the transmission shaft 6 can realize the limiting fixation of the baffle 42 while realizing the torque transmission between the motor 2 and the cutter shaft 41, and the function is more diverse. In addition, a plurality of vertically extending limiting ribs are provided on the outer surface of the transmission shaft 6, and there is no need to set additional interference ribs, which helps to simplify the structure of the transmission shaft 6, facilitate its production and reduce production costs.

[0047] As a preference under this embodiment, the limiting shaft 442 also includes a mating surface located above the limiting surface 441 and arranged opposite to the limiting surface 441. The mating surface, the side wall of the limiting shaft 442 and the limiting surface 441 form a limiting groove to clamp the sleeve 422.

[0048] By forming a limiting groove to clamp the sleeve 422 through the mating surface, the side wall of the limiting shaft 442 and the limiting surface 441, the sleeve 422 can not only achieve the limitation of the two through interference fit after being sleeved on the limiting shaft 442, but also further achieve axial limitation and fixation of the sleeve 422 through the limiting groove, further avoiding the situation in which the food collides with the annular baffle 421 during food processing and causes the baffle 42 to move up and down, and further improving the reliability of the cooperation between the baffle 42 and the limiting shaft 442.

[0049] Preferably, if Figure 3 As shown, an interference rib 4221 is provided on one of the outer wall of the limiting shaft 442 or the inner wall of the sleeve 422, and an interference groove 4421 that cooperates with the interference rib 4221 is provided on the other of the two. More preferably, the interference rib 4221 is provided on the inner wall of the sleeve 422, and the interference groove 4421 is provided on the outer wall of the limiting shaft 442, which helps to further improve the interference fit between the sleeve 422 and the limiting shaft 442.

[0050] As a preferred embodiment of the present application, Figure 3 As shown, the thickness L1 of the sleeve 422 and the thickness L2 of the annular baffle 421 satisfy: 1 / 3≤L2 / L1≤2 / 3.

[0051] By ensuring that the thickness L1 of the sleeve 422 and the thickness L2 of the annular baffle 421 meet the following conditions: 1 / 3≤L2 / L1≤2 / 3, the sleeve 422 is prevented from being too thin relative to the annular baffle 421, which may cause the sleeve 422 to be easily deformed when the user presses the sleeve 422 downward, causing the sleeve 422 to be pressed below the limit surface 441, thereby making it difficult for the user to pull it out; at the same time, the sleeve 422 is prevented from being too thick relative to the annular baffle 421, which may cause the sleeve 422 to be difficult to deform when the user presses down on the blade shaft 41, thereby making it difficult to press it down. While ensuring that the baffle 42 and the blade shaft 41 are easy to assemble, the sleeve 422 can also be prevented from being easily deformed and over-assembled.

[0052] It should be noted that the present application does not make any specific limitation on the material of the baffle 42. As a preferred embodiment of the present application, Figure 3 As shown, the annular baffle 421 is a flexible member, and the thickness of the outer end of the annular baffle 421 is less than the thickness on the side close to the sleeve 422. More preferably, the thickness of the annular baffle 421 gradually decreases radially outward from the sleeve 422, and the top surface can be a flat surface, and the bottom surface can be an inclined surface extending upward; or the top surface can be an inclined surface extending downward, and the bottom surface can be an inclined surface extending upward.

[0053] By setting the annular baffle 421 as a flexible part, during the food processing process, part of the food moves upward and is squeezed onto the annular baffle 421 under the stirring action of the mixing blade 4. With the help of the flexibility of the annular baffle 421, it can undergo a certain deformation, effectively avoiding the situation where the annular baffle 421 is a rigid part and is broken when it is squeezed. At the same time, the thickness of the outer end of the annular baffle 421 is less than the thickness of the side close to the shaft sleeve 422, which not only ensures the stability of the connection between the annular baffle 421 and the shaft sleeve 422, but also avoids the situation where the connection between the annular baffle 421 and the shaft sleeve 422 is thin and easy to break, but also when the side away from the shaft sleeve 422 is deformed upward, it can cover the avoidance opening 51 on the cup cover 5, thereby further avoiding the situation where food overflows.

[0054] As a preferred embodiment of the present application, Figure 4 As shown, the stirring blade 4 further includes a blade 43 provided on the blade shaft 41 , and the diameter D1 of the blade 43 and the diameter D2 of the annular baffle 421 satisfy: 1 / 5≤D2 / D1≤1 / 3.

[0055] By setting the diameter D1 of the blade 43 and the diameter D2 of the annular baffle 421 to satisfy: 1 / 5≤D2 / D1≤1 / 3, the annular baffle 421 can press down the food during food processing and achieve sufficient whipping under the action of the blade 43 below, which helps to improve the processing effect of the food and avoids the situation where the diameter of the annular baffle 421 is smaller than the diameter of the blade 43, resulting in poor downward pressure on the food.

[0056] As a preferred embodiment of the present application, Figure 2 As shown, the food processor also includes a cup cover 5 arranged on top of the cup body 3. The cup cover 5 is provided with an avoidance opening 51 for the knife shaft 41 and the motor 2 to cooperate with each other in transmission. The radius R1 of the avoidance opening 51 and the radius R2 of the annular baffle 421 satisfy: 0≤R1-R2≤10mm.

[0057] By setting the radius R1 of the avoidance opening 51 and the radius R2 of the annular baffle 421 to satisfy: 0≤R1-R2≤10mm, it is avoided that the radius of the annular baffle 421 is smaller than the radius of the avoidance opening 51, which causes food to splash outward through the gap between the annular baffle 421 and the avoidance opening 51; at the same time, it is avoided that the radius of the annular baffle 421 is too large compared to the radius of the avoidance opening 51, which causes the annular baffle 421 to be easily deformed, resulting in its shielding failure.

[0058] As a preferred embodiment of the present application, Figure 2 As shown, the stirring blade 4 further includes a plurality of blades 43 provided on the blade shaft 41 , and the distance between the top end of the blade 43 and the top wall L3 of the annular baffle 421 satisfies the following: 5 mm ≤ L3 ≤ 10 mm.

[0059] By setting the distance L3 between the top end of the blade 43 and the top wall of the annular baffle 421 to satisfy: 5mm≤L3≤10mm, it is avoided that the top end of the blade 43 is too close to the top wall of the annular baffle 421, which causes the food to splash out directly from the gap between the upper end surface of the annular baffle 421 and the cup cover 5 when it is crushed; at the same time, it is avoided that the top end of the blade 43 is too far from the top wall of the annular baffle 421, which causes the annular baffle 421 to have a poor downward pressure effect on the food, resulting in a poor food processing effect.

[0060] It should be noted that the present application does not specifically limit the structure of the stirring blade 4. Figure 7 As shown, it can be a dough knife, which includes a dough paddle 45 provided on the side of the knife shaft 41, a baffle 42 provided above the dough paddle 45, and a gap between the bottom surface of the annular baffle 421 and the dough paddle 45. It can also be a crushing knife, which can be used for mincing meat, chopping vegetables, household supplementary food, etc.

[0061] As a preferred embodiment of the present application, Figure 5 As shown, an arcuate surface 423 is provided between the shaft sleeve 422 and the annular baffle 421 , thereby reducing stress concentration at the connection between the shaft sleeve 422 and the annular baffle 421 , avoiding the situation where the connection between the two is easily broken, and helping to extend the service life of the baffle 42 .

[0062] The technical solutions protected by this utility model are not limited to the above-described embodiments. It should be noted that the combination of the technical solutions of any one embodiment with the technical solutions of one or more other embodiments falls within the scope of protection of this utility model. Although the above description of this utility model has been provided in detail using general instructions and specific embodiments, it is obvious to those skilled in the art that modifications or improvements can be made based on this utility model. Therefore, such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
