Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, the first purpose of the utility model is to provide a grinding device.

[0005] The second purpose of the utility model is to provide an electrical device.

[0006] To achieve at least one of the above-mentioned purposes, according to the first aspect of the utility model, a grinding device is proposed, comprising: a shell having a mounting cavity, the shell defining a feed port; a grinding assembly installed in the mounting cavity, the grinding assembly comprising: a cutter disc assembly, including a mounting disc, at least two rotating shafts and at least two first grinding members, the mounting disc being capable of rotating relative to the shell, the rotating shaft being connected to the mounting disc, the first grinding member being connected to the corresponding rotating shaft, the first grinding member being used for grinding an object entering through the feed port; wherein the first grinding member is capable of rotating relative to the mounting disc around the rotating shaft and is capable of moving relative to the mounting disc in a direction toward or away from the center of the mounting disc.

[0007] The grinding device proposed in the present application includes a shell and a grinding assembly, wherein the shell has an installation cavity, the installation cavity is used to accommodate and install the grinding assembly, the shell defines a feed port, and objects such as objects can enter the grinding device through the feed port. The grinding assembly is installed in the installation cavity, and the grinding assembly is used to grind objects entering through the feed port. The grinding assembly includes a cutter disc assembly, and the cutter disc assembly can rotate relative to the shell, and the object can be ground by the cutter disc assembly. The cutter disc assembly includes a mounting plate and at least two first grinding members, and the first grinding member is installed on the mounting plate, and the mounting plate can rotate relative to the shell. When the mounting plate rotates, the mounting plate drives the first grinding member to rotate relative to the shell. The first grinding member can grind the object during the process of rotating relative to the shell.

[0008] Furthermore, the cutter disc assembly further includes at least two rotating shafts, and the first grinding member is mounted on the mounting disc via the rotating shafts. Specifically, the rotating shaft is fixedly connected to the mounting disc, and the first grinding member is connected to the corresponding rotating shaft. The first grinding member can rotate relative to the mounting disc around the rotating shaft. When an object enters the grinding device from the feed port and falls onto the cutter disc assembly, if the object is large in size, the first grinding member can be squeezed by the object and rotate relative to the mounting disc to avoid the large object and prevent the first grinding member from getting stuck.

[0009] Understandably, if the object is too large, the first grinding member cannot avoid the object by rotating, which may easily cause the first grinding member to get stuck. In order to avoid the above problem, the present application designs the first grinding member to be able to move relative to the mounting plate in a direction toward or away from the center of the mounting plate. In this way, the movement range of the first grinding member can be expanded, the ability of the first grinding member to avoid objects is improved, the possibility of the first grinding member being stuck by the object is reduced, and the overall reliability of the grinding device is improved.

[0010] By designing the first grinding member to be able to rotate relative to the mounting disk and to move relative to the mounting disk in a direction toward or away from the center of the mounting disk, the movement range of the first grinding member is expanded, the ability of the first grinding member to avoid objects is improved, the possibility of the first grinding member being stuck by objects is reduced, and the overall reliability of the grinding device is improved.

[0011] According to the above-mentioned grinding device of the utility model, it can also have the following distinguishing technical features:

[0012] In some technical solutions, optionally, any first grinding member is provided with a connecting hole adapted to the rotating shaft, and any rotating shaft is inserted into the corresponding connecting hole, and the first grinding member can rotate around the corresponding rotating shaft relative to the mounting disk; wherein, the size of the connecting hole in the direction toward or away from the center of the mounting disk is larger than the size of the rotating shaft, so that the first grinding member can move relative to the mounting disk in the direction toward or away from the center of the mounting disk.

[0013] In this technical solution, the connection relationship between the first grinding member and the mounting disk is defined. In order to enable the first grinding member to rotate relative to the mounting disk around the rotating shaft, the present application sets a connecting hole on any first grinding member, the connecting hole is adapted to the rotating shaft, and any rotating shaft is inserted into the connecting hole on the corresponding first grinding member. Since the rotating shaft is fixedly connected to the mounting disk, the first grinding member can rotate relative to the mounting disk around the rotating shaft.

[0014] Furthermore, in order to enable the first grinding member to move relative to the mounting disk in a direction toward or away from the center of the mounting disk, the present application sets the connecting hole as a long hole structure with a size larger than the rotating shaft. Specifically, in the direction toward or away from the center of the mounting disk, the size of the connecting hole is larger than the size of the rotating shaft. In this way, the first grinding member has the freedom to move in a direction toward or away from the center of the mounting disk. When the volume of the object dropped from the feed port to the cutter disc assembly is too large, the first grinding member can avoid the object through a variety of movement methods, namely, rotating relative to the mounting disk and moving relative to the mounting disk in a direction toward or away from the center of the mounting disk, so as to avoid the first grinding member being stuck by the object, thereby improving the reliability of the grinding device.

[0015] In some technical solutions, optionally, the cutter disc assembly also includes: a plurality of limit members, which are used to limit the first grinding member, and at least two of the plurality of limit members are respectively arranged on both sides of the corresponding first grinding member, so that the first grinding member can rotate within a preset angle range relative to the mounting disc.

When the first limit member rotates around the rotating shaft relative to the mounting disk, when the first limit member rotates to the limit member, the limit member stops the first grinding member to limit the first grinding member. Since the first grinding member can only rotate between the limit members on both sides, the first grinding member can be rotated within a preset angle range relative to the mounting disk, thereby preventing the first grinding member from being difficult to reset due to excessive rotation angle, which leads to a decrease in the grinding effect.

[0017] In some technical solutions, optionally, the blade disc assembly further includes: a plurality of stirring protrusions, which are arranged on the surface of the mounting disc, and the stirring protrusions are used to stir the object.

[0022] Furthermore, the second grinding member is arranged on the inner wall of the fixed ring, and the first grinding member and the second grinding member can cooperate to grind the object. Specifically, any first grinding member has a grinding groove, the second grinding member protrudes from the inner wall of the fixed ring, the second grinding member is adapted to the grinding groove, and when the cutter head assembly rotates relative to the housing, the mounting plate drives the first grinding member to rotate relative to the second grinding member, and the second grinding member and the grinding groove on the first grinding member generate relative motion to grind the object.

[0023] By arranging the second grinding member in the grinding assembly and arranging the second grinding member on the inner wall of the fixed ring fixed relative to the housing, the object can be ground through the relative movement between the first grinding member and the second grinding member.

[0024] In some technical solutions, optionally, the grinding assembly also includes: a plurality of mounting teeth, arranged on the outer wall of the fixed ring; a plurality of mounting grooves, arranged on the inner wall of the shell, and the mounting teeth can be inserted into the corresponding mounting grooves to limit the fixed ring.

In order to install and fix the fixed ring, the present application provides structures for fixing the fixed ring on the fixed ring and the housing, respectively. Specifically, the outer wall of the fixed ring is provided with a plurality of mounting teeth, and the inner wall of the housing is provided with a plurality of mounting grooves adapted to the mounting teeth. The mounting teeth can be inserted into the corresponding mounting grooves to limit the fixed ring so that the fixed ring can be fixed relative to the housing.

[0026] In a possible technical solution, a plurality of mounting teeth are evenly distributed on the outer wall of the fixed ring along the circumference of the fixed ring, and a plurality of mounting grooves are evenly distributed on the inner wall of the shell along the circumference of the shell, so that the fixed ring is subjected to balanced force and remains stable.

[0027] Furthermore, the top of the fixed ring has a flange, which extends in a direction toward the outside of the fixed ring. The flange can overlap with the shell to limit the fixed ring in the height direction.

[0030] In this technical solution, the fixed ring is further defined. The wall surface of the fixed ring is provided with a plurality of through holes, and the material becomes smaller particles after being ground by the first grinding member and the second grinding member. Such smaller particles can be discharged to the outside of the fixed ring through the through holes. There is a gap between the wall surface of the fixed ring and the inner wall of the installation cavity, and the wall surface of the fixed ring and the inner wall of the installation cavity define a discharge cavity, and the through holes are connected to the discharge cavity, and the ground objects can flow into the discharge cavity through the through holes.

Furthermore, any discharge port is inclined in the direction of the forward rotation of the cutter disc assembly. It can be understood that since the cutter disc assembly can rotate relative to the housing, the cutter disc assembly can drive the object to rotate in the same direction relative to the housing, and by setting the discharge port to be inclined in the direction of the forward rotation of the cutter disc assembly, it is beneficial to discharge the object through the discharge port.

DETAILED DESCRIPTION

[0062] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0063] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may 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 embodiments disclosed below.

[0064] Refer to the following Figures 1 to 9 The grinding device 100 and the electrical equipment provided according to some embodiments of the present invention are described.

[0065] In one embodiment according to the present application, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the present application proposes a grinding device 100, comprising: a shell 110, having a mounting cavity 111, the shell 110 defines a feed port 112; a grinding assembly 120, mounted in the mounting cavity 111, the grinding assembly 120 comprising: a cutter disc assembly 130, comprising a mounting disc 131, at least two rotating shafts 132 and at least two first grinding members 133, the mounting disc 131 being rotatable relative to the shell 110, the rotating shaft 132 being connected to the mounting disc 131, the first grinding members 133 being connected to the corresponding rotating shaft 132, the first grinding members 133 being used for grinding an object entering through the feed port 112; wherein the first grinding members 133 are rotatable relative to the mounting disc 131 around the rotating shaft 132 and are movable relative to the mounting disc 131 in a direction toward or away from the center of the mounting disc 131.

[0066] The grinding device 100 proposed in the present application includes a housing 110 and a grinding assembly 120, wherein the housing 110 has an installation cavity 111, the installation cavity 111 is used to accommodate and install the grinding assembly 120, and the housing 110 defines a feed port 112, through which objects and other objects can enter the grinding device 100. The grinding assembly 120 is installed in the installation cavity 111, and the grinding assembly 120 is used to grind the object entering through the feed port 112. The grinding assembly 120 includes a cutter head assembly 130, and the cutter head assembly 130 can rotate relative to the housing 110, and the object can be ground by the cutter head assembly 130. The cutter head assembly 130 includes a mounting plate 131 and at least two first grinding members 133, and the first grinding members 133 are mounted on the mounting plate 131, and the mounting plate 131 can rotate relative to the housing 110. When the mounting plate 131 rotates, the mounting plate 131 drives the first grinding members 133 to rotate relative to the housing 110. The first grinding member 133 can grind the object while rotating relative to the housing 110 .

[0067] Furthermore, the cutter disc assembly 130 further includes at least two rotating shafts 132, and the first grinding member 133 is mounted on the mounting disc 131 via the rotating shafts 132. Specifically, the rotating shafts 132 are fixedly connected to the mounting disc 131, and the first grinding member 133 is connected to the corresponding rotating shafts 132. The first grinding member 133 can rotate relative to the mounting disc 131 around the rotating shafts 132. When an object enters the grinding device 100 from the feed port 112 and falls onto the cutter disc assembly 130, if the object is large in size, the first grinding member 133 can be squeezed by the object and rotate relative to the mounting disc 131 to avoid the large object and prevent the first grinding member 133 from getting stuck.

[0068] Understandably, if the object is too large, the first grinding member 133 cannot avoid the object by rotating, which may easily cause the first grinding member 133 to get stuck. In order to avoid the above problem, the present application designs the first grinding member 133 to be able to move relative to the mounting plate 131 in a direction toward or away from the center of the mounting plate 131. In this way, the movement range of the first grinding member 133 can be expanded, the ability of the first grinding member 133 to avoid objects is improved, the possibility of the first grinding member 133 being stuck by objects is reduced, and the overall reliability of the grinding device 100 is improved.

[0069] By designing the first grinding member 133 to be able to rotate relative to the mounting disk 131 and to move relative to the mounting disk 131 in a direction toward or away from the center of the mounting disk 131, the movement range of the first grinding member 133 is expanded, the ability of the first grinding member 133 to avoid objects is improved, the possibility of the first grinding member 133 being stuck by objects is reduced, and the overall reliability of the grinding device 100 is improved.

[0070] In some embodiments, optionally, Figure 5 and Figure 6 As shown, any first grinding member 133 is provided with a connecting hole 137 adapted to the rotating shaft 132, and any rotating shaft 132 is inserted into the corresponding connecting hole 137, and the first grinding member 133 can rotate around the corresponding rotating shaft 132 relative to the mounting disk 131; wherein, the size of the connecting hole 137 in the direction toward or away from the center of the mounting disk 131 is larger than the size of the rotating shaft 132, so that the first grinding member 133 can move relative to the mounting disk 131 in the direction toward or away from the center of the mounting disk 131.

[0071] In this embodiment, the connection relationship between the first grinding member 133 and the mounting plate 131 is defined. In order to enable the first grinding member 133 to rotate relative to the mounting plate 131 around the rotating shaft 132, the present application sets a connecting hole 137 on any first grinding member 133, and the connecting hole 137 is adapted to the rotating shaft 132. Any rotating shaft 132 is inserted into the connecting hole 137 on the corresponding first grinding member 133. Since the rotating shaft 132 is fixedly connected to the mounting plate 131, the first grinding member 133 can rotate relative to the mounting plate 131 around the rotating shaft 132.

[0072] Furthermore, in order to enable the first grinding member 133 to move relative to the mounting disk 131 in a direction toward or away from the center of the mounting disk 131, the present application sets the connection hole 137 as a long hole structure with a size larger than the rotating shaft 132. Specifically, in the direction toward or away from the center of the mounting disk 131, the size of the connection hole 137 is larger than the size of the rotating shaft 132. In this way, the first grinding member 133 has the freedom to move in the direction toward or away from the center of the mounting disk 131. When the volume of the object dropped from the feed port 112 to the cutter head assembly 130 is too large, the first grinding member 133 can avoid the object through a variety of movement modes, that is, rotating relative to the mounting disk 131 and moving relative to the mounting disk 131 in a direction toward or away from the center of the mounting disk 131, so as to avoid the first grinding member 133 being stuck by the object, thereby improving the reliability of the grinding device 100.

[0073] In some embodiments, optionally, Figure 3 , Figure 4 and Figure 5 As shown, the cutter disc assembly 130 also includes: a plurality of limit members 135, the limit members 135 are used to limit the first grinding member 133, and at least two of the plurality of limit members 135 are respectively arranged on both sides of the corresponding first grinding member 133, so that the first grinding member 133 can rotate within a preset angle range relative to the mounting disc 131.

[0074] In this embodiment, the structure of the cutter disc assembly 130 is further defined. In order to limit the first grinding member 133, the present application further provides a plurality of limit members 135 in the cutter disc assembly 130. The limit members 135 are provided on the mounting plate 131 and protrude from the surface of the mounting plate 131, and at least two of the plurality of limit members 135 are provided on both sides of the corresponding first grinding member 133. When the first limit member 135 rotates relative to the mounting plate 131 around the rotating shaft 132, when the first limit member 135 rotates to the limit member 135, the limit member 135 stops the first grinding member 133 to limit the first grinding member 133. Since the first grinding member 133 can only rotate between the limit members 135 on both sides, the first grinding member 133 can rotate within a preset angle range relative to the mounting plate 131, thereby preventing the first grinding member 133 from being difficult to reset due to the large rotation angle, which may cause the grinding effect to decrease.
