Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electrical appliances, and particularly relates to a clamping prevention device, a grinder and a grinding equipment. BACKGROUND

[0002] A coffee grinder is a kind of powder grinding tool for cutting and grinding coffee beans into coffee powder when the coffee beans are cut by a mechanical cutter driven by a motor at a high speed. The coffee beans inevitably contain some hard impurities, such as stones, coconut shells and other hard objects.

[0003] When the coffee beans are ground, the hard impurities mixed in the coffee beans enter the grinder, and the hard impurities will clump the whole grinder when the grinder is ground, resulting in damage of the cutter. SUMMARY

[0004] To solve the above technical problems, the application provides a clamping prevention device, a grinder and a grinding equipment, which can at least solve the technical problem that the hard impurities will clump the whole grinder when the grinder is ground, resulting in damage of the cutter.

[0005] The technical scheme of the application is as follows:

[0006] The clamping prevention device is characterized in that the clamping prevention device is installed on an equipment main body, and the clamping prevention device comprises: a bearing part provided with a cavity for accommodating a cutter assembly; a pressing plate detachably arranged at an end of the bearing part; at least one limiting part connected with the pressing plate and the bearing part and / or the equipment main body; and at least one elastic part, two ends of the elastic part being respectively in contact with the end of the pressing plate and the end of the corresponding limiting part away from the bearing part, the elastic part acting on the pressing plate, and the pressing plate applying an acting force to the cutter assembly to make two cutter edges of the cutter assembly close to each other.

[0007] Since the bearing member is provided with a chamber for accommodating the cutter assembly, the cutter assembly is protected by the chamber to ensure the safety of the cutter assembly. Since the pressing plate is detachably provided at the end of the bearing member, at least one limiting member is provided through the pressing plate and connected with the bearing member and / or the main body of the device, the at least one limiting member is supported by the bearing member and / or the main body of the device. Since the two ends of the at least one elastic member are respectively in contact with the pressing plate and the end of the corresponding limiting member away from the bearing member, the elastic member acts on the pressing plate, the pressing plate applies a force to the cutter assembly to make the two blades of the cutter assembly close to each other. Therefore, when a hard foreign object enters the cutter assembly, the grinding torque becomes larger. At this time, along the axial direction of the bearing member, one of the two blades of the cutter assembly moves in the chamber in the direction of the pressing plate to lift the pressing plate, providing a space for the movement of the cutter assembly in the axial direction of the bearing member. The elastic member is compressed between the pressing plate and the limiting member, the distance between the two blades of the cutter assembly is increased, and the hard foreign object is discharged between the two blades of the cutter assembly to prevent damage to the cutter assembly and ensure the safety of the cutter assembly, thereby prolonging the service life of the grinder. When the hard foreign object is discharged between the two blades of the cutter assembly, the elastic member applies a force to the pressing plate toward one of the two blades of the cutter assembly under the action of the elastic restoring force of the elastic member, along the axial direction of the bearing member, so that the pressing plate moves toward the bearing member. The pressing plate is pressed on the cutter assembly, and the pressing plate drives one of the two blades of the cutter assembly to move, so that one of the two blades of the cutter assembly returns to the original position and can perform normal grinding operation.

[0008] In some embodiments, the chamber extends through the bearing member along the axial direction of the bearing member, and the pressing plate is provided at the end of the chamber to ensure that the pressing plate can be pressed on the cutter assembly.

[0009] In some embodiments, the cutter assembly includes a first cutter and a second cutter each provided with the blade, and the first cutter and / or the second cutter is slidably provided in the chamber along the axial direction of the bearing member, so that the distance between the first cutter and the second cutter can be changed.

[0010] In some embodiments, the limiting member includes a connecting portion provided through the pressing plate and connected with the bearing member, and a limiting portion provided at the end of the connecting portion away from the bearing member to limit the elastic member.

[0011] In some embodiments, the elastic member is sleeved on the connecting portion, and the two ends of the elastic member are respectively in contact with the pressing plate and the limiting portion to ensure that the elastic member can apply a force to the pressing plate toward one of the two blades of the cutter assembly.

[0012] In some embodiments, the anti-sticking device further comprises at least one guide arranged on the carrier and penetrating the pressing plate, so that the pressing plate can only move along the axial direction of the carrier.

[0013] In some embodiments, the limiting member is connected with the corresponding guide, so as to reduce the processing difficulty and cost.

[0014] In some embodiments, at least one support is arranged on the cavity wall of the cavity, and the cutter assembly is detachably arranged on the support, so as to avoid the cutter assembly from falling off the cavity.

[0015] Based on the same inventive concept, the present application further provides a grinder comprising a cutter assembly, a driving assembly and the anti-sticking device.

[0016] In some embodiments, the grinder further comprises a granularity adjuster rotatably connected with the driving assembly, and the carrier is threadedly connected with the granularity adjuster; when the granularity adjuster rotates on the driving assembly, the carrier moves along the axial direction of the carrier relative to the granularity adjuster, so as to change the distance between the first cutter and the second cutter, and adjust the granularity of the grinding of the grinder.

[0017] Based on the same inventive concept, the present application further provides a grinding device comprising the grinder.

[0018] In some embodiments, the grinding device comprises a coffee grinder, a bean grinder or a flour mill. BRIEF DESCRIPTION OF DRAWINGS

[0041] In order to reduce the possibility that hard foreign matter will jam the entire grinder, causing the cutter to be damaged, the grinder will set the anti-jamming of the crushing system, mainly setting the torque limiting slip mechanism between the power system and the lower grinding cutter, when the torque reaches the set limit, the lower grinding cutter will slip to protect the cutter. However, this torque limiting slip mechanism has a durability failure problem, which cannot protect the grinding cutter, resulting in damage to the cutter by hard foreign matter, reducing the service life of the grinder.

[0042] The anti-jamming device, grinder and grinding equipment provided by the embodiments of the present application can improve the above problems. The anti-jamming device, grinder and grinding equipment provided by the embodiments of the present application are intended to at least solve the technical problem that hard foreign matter will jam the entire grinder during grinding, causing the cutter to be damaged.

[0043] The present application will be described below in conjunction with the drawings and specific embodiments:

[0044] Figure 1 The structure diagram of the grinder of some embodiments; Figure 2 The structure diagram of the grinder of some embodiments; Figure 1 The exploded view of the grinder; Figure 3 The structure diagram of the grinder of some embodiments; Figure 1 The cross-sectional view of the grinder. In combination with Figure 1 , Figure 2 and Figure 3 , the anti-jamming device of the present embodiment comprises a bearing part 10, a pressing plate 20, at least one limiting part 30 and at least one elastic part 40. The bearing part 10 is provided with a cavity for accommodating the cutter assembly 50. The pressing plate 20 is detachably arranged at the end of the bearing part 10. The at least one limiting part 30 is connected between the pressing plate 20 and the bearing part 10 and / or the equipment body. The at least one elastic part 40 is in contact with the end of the pressing plate 20 and the corresponding limiting part 30 away from the bearing part 10 at both ends, respectively. The elastic part 40 acts on the pressing plate 20, and the pressing plate 20 applies a force to the cutter assembly 50, so that the two cutting edges of the cutter assembly 50 are close to each other.

[0045] The number of limiting parts 30 can be one or more.

[0046] The number of elastic members 40 can be one or more.

[0047] The device body can be an external frame.

[0048] Since the carrier 10 is provided with a chamber for accommodating the cutter assembly 50, the cutter assembly 50 is protected by the chamber to ensure the safety of the cutter assembly 50. Since the pressing plate 20 is detachably arranged at the end of the carrier 10, at least one limiting member 30 is arranged through the pressing plate 20 and connected with the carrier 10 and / or the device body, the at least one limiting member 30 is supported by the carrier 10 and / or the device body. Since the two ends of the at least one elastic member 40 respectively abut against the end of the carrier 10 away from the pressing plate 20 and the corresponding limiting member 30, the elastic member 40 acts on the pressing plate 20, and the pressing plate 20 exerts a force on the cutter assembly 50 to make the two blades of the cutter assembly 50 close to each other. Therefore, when a hard foreign matter enters the cutter assembly 50, the grinding torque becomes large. At this time, in the axial direction of the carrier 10, one of the two blades of the cutter assembly 50 moves in the chamber in the direction of the pressing plate 20 to lift the pressing plate 20, thereby providing a space for the movement of the cutter assembly 50 in the axial direction of the carrier 10. The elastic member 40 is compressed between the pressing plate 20 and the limiting member 30, the distance between the two blades of the cutter assembly 50 becomes larger, and the hard foreign matter is discharged from between the two blades of the cutter assembly 50, thereby preventing the hard foreign matter from damaging the cutter assembly 50 and ensuring the safety of the cutter assembly 50, and the service life of the grinder is ensured. When the hard foreign matter is discharged from between the two blades of the cutter assembly 50, the elastic member 40 exerts a force on the pressing plate 20 towards one of the two blades of the cutter assembly 50 under the action of the elastic restoring force of the elastic member 40, in the axial direction of the carrier 10, so that the pressing plate 20 moves towards the carrier 10. The pressing plate 20 is arranged on the cutter assembly 50, and the pressing plate 20 drives one of the two blades of the cutter assembly 50 to move, so that one of the two blades of the cutter assembly 50 returns to the original position, and normal grinding operation can be performed.

[0049] In some embodiments, the two blades of the cutter assembly 50 can move in the chamber in the axial direction of the carrier 10 by the carrier 10, the pressing plate 20, the limiting member 30 and the elastic member 40 to change the distance between the two blades of the cutter assembly 50. The structure is simple, the cost is low, the durability is good, the safety of the two blades of the cutter assembly 50 is ensured, and the service life of the grinder is also ensured.

[0050] In combination Figure 2 and Figure 3In some embodiments, in order to ensure that the pressing plate 20 can press the cutter assembly 50, a cavity is formed through the carrier 10 along the axial direction of the carrier 10, and the pressing plate 20 is arranged at the end of the cavity, so that the pressing plate 20 is not blocked by the cutter assembly 50, and the pressing plate 20 can be in contact with the cutter assembly 50.

[0051] In some embodiments, when one of the two blades of the cutter assembly 50 is forced to move in the direction of the pressing plate 20 in the cavity, the one of the two blades of the cutter assembly 50 can push up the pressing plate 20, and the cutter assembly 50 is provided with a space for movement along the axial direction of the carrier 10. When the hard foreign matter is discharged between the two blades of the cutter assembly 50, the elastic member 40 can push the one of the two blades of the cutter assembly 50 back to the original position through the pressing plate 20 under the elastic restoring force of the elastic member 40, and the normal grinding operation can be performed.

[0052] In combination Figure 3 In some embodiments, in order to facilitate the pressing plate 20 to abut against one of the two blades of the cutter assembly 50, the pressing plate 20 is provided with a protrusion 201 at the end of the cavity, and the protrusion 201 can abut against the one of the two blades of the cutter assembly 50, so that the pressing plate 20 can drive the one of the two blades of the cutter assembly 50 to move.

[0053] In some embodiments, in order to change the distance between the two blades of the cutter assembly 50, the cutter assembly 50 comprises a first cutter 501 and a second cutter 503, both of which are provided with blades, and the first cutter 501 and / or the second cutter 503 are slidably arranged in the cavity along the axial direction of the carrier 10, that is, when a hard foreign matter enters between the cutter assembly 50 and the second cutter 503, the first cutter 501 and / or the second cutter 503 slide in the cavity along the axial direction of the carrier 10, so that the first cutter 501 or the second cutter 503 can move in the direction of the pressing plate 20.

[0054] In some embodiments, in order to ensure that the first cutter 501 and / or the second cutter 503 can slide in the cavity along the axial direction of the carrier 10, the cross-sectional area of the cavity along the axial direction of the carrier 10 matches the cross-sectional area of the first cutter 501 and / or the second cutter 503, that is, the cavity wall of the cavity limits the first cutter 501 and / or the second cutter 503 along the radial direction of the carrier 10, so that the first cutter 501 and / or the second cutter 503 can only slide in the cavity along the axial direction of the carrier 10, and the position of the first cutter 501 and / or the second cutter 503 along the radial direction of the carrier 10 cannot be changed.

[0055] In combination Figure 2 And Figure 3In some embodiments, in order to limit the elastic member 40, the limiting member 30 comprises a connecting portion 301 and a limiting portion 302. The connecting portion 301 is connected to the pressing plate 20 and the carrier 10, so as to be supported by the carrier 10. The limiting portion 302 is arranged at the end of the connecting portion 301 away from the carrier 10, so as to limit the elastic member 40. The limiting member 30 can be a bolt, the connecting portion 301 can be a screw rod, and the limiting portion 302 can be a nut.

[0056] In combination Figure 2 And Figure 3 In some embodiments, in order to ensure that the elastic member 40 can apply a force to the pressing plate 20 towards one of the two cutting edges of the tool assembly 50, the elastic member 40 is sleeved on the connecting portion 301, and the two ends of the elastic member 40 are in contact with the pressing plate 20 and the limiting portion 302 respectively and are sleeved on the corresponding limiting member 30. The elastic member 40 can be a spring.

[0057] In some embodiments, along the axial direction of the carrier 10, one of the two cutting edges of the tool assembly 50 moves in the chamber towards the pressing plate 20, so as to lift the pressing plate 20, so that the elastic member 40 is compressed between the pressing plate 20 and the limiting portion 302. When the hard foreign matter is discharged between the two cutting edges of the tool assembly 50, under the action of the elastic recovery force of the elastic member 40 and the limiting portion 302, the elastic member 40 applies a force to the pressing plate 20 towards one of the two cutting edges of the tool assembly 50, so that the pressing plate 20 moves towards the carrier 10.

[0058] In combination Figure 2 And Figure 3 In some embodiments, in order to ensure that the pressing plate 20 can only move along the axial direction of the carrier 10, the anti-jamming device further comprises at least one guide member 70. The at least one guide member 70 is arranged on the carrier 10 and penetrates the pressing plate 20. The number of the guide member 70 can be one or more.

[0059] In some embodiments, when the pressing plate 20 moves along the axial direction of the carrier 10, the pressing plate 20 moves on the guide member 70, the movement of the pressing plate 20 is guided by the guide member 70, so as to ensure the stability of the movement of the pressing plate 20, avoid the change of the position of the pressing plate 20 along the radial direction of the carrier 10, and further ensure that the pressing plate 20 can move along the axial direction of the carrier 10.

[0060] In some embodiments, the pressing plate 20 is provided with at least one guide hole, and the guide member 70 penetrates the corresponding guide hole, so as to guide the movement of the pressing plate 20 and ensure the smooth movement of the pressing plate 20. The diameter of the guide member 70 matches the diameter of the guide hole.

[0061] In some embodiments, in order to reduce the processing difficulty and the processing cost, the limiting member 30 is connected with the corresponding guide member 70, which can reduce the number of holes on the pressing plate 20, and the fixing of the limiting member 30 is realized through the guide member 70.

[0062] In some other embodiments, a groove can be formed on the end face of the bearing member 10 facing the pressing plate 20, one end of the elastic member 40 is connected with the bottom wall of the groove, and the other end is connected with the pressing plate 20. When the pressing plate 20 acts in the direction away from the cutter assembly 50, the elastic member 40 is stretched. When the hard foreign matter is discharged between the two blades of the cutter assembly 50, the elastic member 40 is retracted under the action of the elastic restoring force of the elastic member 40, so as to drive the pressing plate 20 to act in the direction of one of the two blades of the cutter assembly 50. The pressing plate 20 drives one of the two blades of the cutter assembly 50 to act, so as to restore one of the two blades of the cutter assembly 50 to the original position.

[0063] In combination Figure 3 In some embodiments, in order to avoid the cutter assembly 50 from falling out of the chamber, at least one supporting member 80 is arranged on the cavity wall of the chamber, and the cutter assembly 50 is detachably arranged on the supporting member 80. The supporting member 80 supports the cutter assembly 50, so as to ensure the stability of the installation of the cutter assembly 50 in the chamber.

[0064] In combination Figure 3 In some embodiments, at least one abutting member 100 is arranged on the circumferential surface of the cutter assembly 50. When the cutter assembly 50 acts in the direction of the pressing plate 20, the supporting member 80 is separated from the corresponding abutting member 100. The elastic member 40 applies an action force to the pressing plate 20 in the direction of the cutter assembly 50 along the axial direction of the bearing member 10, and the pressing plate 20 drives the cutter assembly 50 to act until the abutting member 100 abuts against the supporting member 80. The supporting member 80 supports the corresponding abutting member 100, so as to restore the cutter assembly 50 to the original position, realize the limiting of the cutter assembly 50, avoid the cutter assembly 50 from falling out of the chamber, and ensure the stability of the installation of the cutter assembly 50 in the chamber.

[0065] In some embodiments, the number of the supporting members 80 can be one or more, and the number of the abutting members 100 can also be one or more. When the number of the supporting members 80 is multiple, the number of the abutting members 100 is also multiple. The multiple supporting members 80 are arranged at equal angles and uniformly spaced along the inner circumferential surface of the chamber, and the multiple abutting members 100 are arranged at equal angles and uniformly spaced along the outer circumferential surface of the cutter assembly 50, so as to ensure the stability of the limiting of the cutter assembly 50, further avoid the cutter assembly 50 from falling out of the chamber, and ensure the stability of the installation of the cutter assembly 50 in the chamber.

[0066] Based on the same inventive concept, this application also proposes a grinder that employs the aforementioned anti-jamming device. The specific structure of the anti-jamming device is as described in the above embodiments. Since it employs all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0067] Combination Figure 1 , Figure 2 and Figure 3 In some embodiments, the grinder includes a cutter assembly 50 and a drive assembly 90. A second cutter 503 of the cutter assembly 50 is connected to the actuating end of the drive assembly 90. The actuating end of the drive assembly 90 drives the second cutter 503 to rotate, thereby grinding coffee beans. The second cutter 503 can be a burr disc.

[0068] In the prior art, when a hard foreign object enters between the tool assembly 50 and the second tool 503, the hard foreign object will jam the entire grinder. At this time, the drive assembly 90 continues to transmit power to the second tool 503, resulting in excessive grinding torque, which may damage the drive assembly 90.

[0069] In some embodiments, when a hard foreign object enters between the two cutting edges of the tool assembly 50, the grinding torque increases. At this time, along the axial direction of the support member 10, one of the two cutting edges of the tool assembly 50 is forced to move towards the pressure plate 20 in the cavity to lift the pressure plate 20. The support member 10 provides movement space for one of the two cutting edges of the tool assembly 50 in the axial direction. The elastic member 40 is compressed so that the elastic member 40 is compressed between the pressure plate 20 and the limiting member 30. The distance between the two cutting edges of the tool assembly 50 increases so that the hard foreign object is discharged from between the two cutting edges of the tool assembly 50, so as to ensure that the second tool 503 can rotate normally, avoid the grinding torque from increasing, and ensure the safety of the drive assembly 90.

[0070] Combination Figure 1 , Figure 2 and Figure 3 In some embodiments, to adjust the particle size of the grinder, the grinder further includes a particle size adjuster 110. The particle size adjuster 110 is rotatably connected to the drive assembly 90, and the carrier 10 is threadedly connected to the particle size adjuster 110. As the particle size adjuster 110 rotates on the drive assembly 100, the carrier 10 moves relative to the particle size adjuster 110 along the axial direction of the carrier 10 to change the distance between the two cutting edges of the tool assembly 50.

[0071] In some embodiments, when the granularity of the grinding of the grinder is to be adjusted, the granularity adjuster 110 rotates on the driving assembly 90 to make the carrier 10 move along the axial direction of the carrier 10 relative to the granularity adjuster 110, and the carrier 10 drives one of the two blades of the cutter assembly 50 to move along the axial direction of the carrier 10 to change the distance between the two blades of the cutter assembly 50, thereby achieving the adjustment of the granularity of the grinding of the grinder.

[0072] In combination Figure 3 In some embodiments, one of the inner circumferential surface of the granularity adjuster 110 and the outer circumferential surface of the driving assembly 90 is provided with an embedded part, and the other is provided with an embedded groove, and the embedded part can be embedded in the embedded groove, thereby achieving the rotatable connection of the granularity adjuster 110 and the driving assembly 90. In some embodiments, the cross-sectional shape of the embedded part is circular, and the embedded groove is an annular groove.

[0073] In some embodiments, the inner circumferential surface of the granularity adjuster 110 is provided with an embedded part, and the outer circumferential surface of the driving assembly 90 is provided with an embedded groove, and the embedded part can be embedded in the embedded groove. Of course, in other embodiments, the outer circumferential surface of the driving assembly 90 is provided with an embedded part, and the inner circumferential surface of the granularity adjuster 110 is provided with an embedded groove, and the embedded part can be embedded in the embedded groove.

[0074] In combination Figure 2 And Figure 3 In some embodiments, the cutter assembly 50 further comprises a cutter support 502. The first cutter 501 is arranged on the cutter support 502 to support the first cutter 501 through the cutter support 502. The cutter support 502 is arranged in the chamber to protect the cutter support 502 and the first cutter 501 through the chamber. In some embodiments, the first cutter 501 can be a cutter disc.

[0075] In combination Figure 2 And Figure 3 In some embodiments, in order to ensure that the coffee beans can be fully ground, the grinder further comprises a stirring member 120. The stirring member 120 is arranged on the action end of the driving assembly 90, and the stirring member 120 is driven to move by the action end of the driving assembly 90. The stirring member 120 stirs the coffee beans to make the coffee beans be fully ground.

[0076] In combination Figure 2 And Figure 3 In some embodiments, in order to push the coffee powder to the coffee powder outlet, the grinder further comprises a sweeping member 130. The sweeping member 130 is arranged on the action end of the driving assembly 90, and the sweeping member 130 is driven to move by the action end of the driving assembly 90. The sweeping member 130 pushes the coffee powder to the coffee powder outlet.

[0077] In combination Figure 2 And Figure 3In some embodiments, the grinder further comprises a connecting piece 60. The connecting piece is sequentially arranged in the stirring piece 120, the second cutter 503 and the powder sweeping piece 130 and the action end of the driving assembly 90, so that the action end of the driving assembly 90 can drive the stirring piece 120, the second cutter 503 and the powder sweeping piece 130 to act. The stirring piece 120, the second cutter 503 and the powder sweeping piece 130 are connected with the action end of the driving assembly 90 through a connecting piece 60, which reduces the cost. The connecting piece 60 can be a bolt.

[0078] Based on the same inventive concept, the application further provides a grinding device which adopts the grinder. The specific structure of the grinder is referred to the above-mentioned embodiments. Since all the technical solutions of the above-mentioned embodiments are adopted, at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments are achieved, which will not be described here.

[0079] In some embodiments, the grinding device is a coffee grinder. Coffee beans fall into the two blades of the cutter assembly 50 through the bean bin, and are ground into coffee powder by the relative rotation between the two blades of the cutter assembly 50.
