Description

Technical Field

[0001] The invention relates to the technical field of grinding, in particular to a grinder. Background Art

[0002] A grinder is a kitchen utensil for grinding food. At present, grinders usually have a male grinding head and a female grinding head. The grinding purpose is achieved by making the male grinding head and the female grinding head rotate relative to each other. Among them, the male grinding head is mostly fixedly connected to the tank body through a support frame. When the male grinding head and the female grinding head rotate relative to each other, stress is applied to the support frame, which may cause damage to the support frame over time. In the prior art, the support frame is generally fixed directly to the tank body, and when the support frame is damaged, the support frame cannot be replaced separately.

[0003] At present, the grinding head and the tank body of the grinder are generally connected by threads. Misalignment may occur during the installation process, causing the seasoning to spill out of the gap between the tank body and the grinding head, which not only increases the user's time cost but also wastes the seasoning. In addition, if the grinder connected by threads is rotated without paying attention to the rotation direction, the grinding head may separate from the tank body and cause the seasoning to spill out. Summary of the invention

[0004] One of the objects of the present application is to provide a grinder that can solve at least one of the defects in the above-mentioned background technology.

[0005] In order to achieve at least one of the above-mentioned purposes, the technical solution adopted in the present application is: a grinder, comprising a grinding head and a tank body; the grinding head is connected to the tank body, a grinding assembly is installed in the grinding head, the grinding assembly comprises a male grinding head and a female grinding head, the male grinding head and the female grinding head cooperate to form a grinding channel for grinding seasonings; a plug is provided at the upper part of the tank body, a socket is provided at the lower part of the grinding head, the plug is plugged into the socket; a support frame for limiting the male grinding head is installed in the grinding head, the lower part of the support frame is used to plug the plug, a base is rotatably installed on the support frame, and the female grinding head is limitedly installed on the base; the base is used to drive the female grinding head to rotate.

[0006] Preferably, the inner wall of the plug is a polygon, the outer wall of the support frame is provided with a polygon matching the inner wall of the plug, and the plug limits the rotation of the support frame through the limit fit of the polygon. Such a setting not only improves the convenience of supporting frame installation, but also allows the supporting frame to be designed as a universal part, and can be replaced separately when the supporting frame is damaged.

[0007] Preferably, the support frame is provided with a support rod, the cross section of the support rod is a polygon, a limit block is installed on the support rod, the limit block is provided with a through hole matching the cross section of the support rod, and the support rod passes through the through hole to limit the rotation of the limit block. This arrangement ensures that the limit block and the tank body will never rotate relative to each other.

[0008] Preferably, the longitudinal cross section of the limit block is in a "T" shape, the male grinding head is provided with a through hole, and the lower part of the limit block is plugged into the through hole; the contact surfaces of the limit block and the male grinding head are provided with mutually matching latches and latch grooves, and the latches are embedded in the latch grooves so that the limit block can limit the rotation of the male grinding head. Through the above arrangement, a relatively fixed connection can be formed between the limit block and the male grinding head; since the material of the male grinding head is mostly ceramic, when the rotation force is too large, the male grinding head contains a large stress; and the latches can unload the force through a certain degree of deformation, effectively reducing the probability of the male grinding head being damaged.

[0009] Preferably, an adjusting member is installed on one end of the support rod away from the support frame, the adjusting member and the support rod are connected by threaded fit, and the adjusting member is used to adjust the relative position between the male grinding head and the female grinding head. In this arrangement, the compression degree of the spring between the male grinding head and the support frame can be controlled by twisting the adjusting rod, and the size of the grinding channel can be changed by changing the relative position of the male grinding head and the female grinding head, thereby achieving the purpose of adjusting the grinding accuracy.

[0010] Preferably, a first baffle is fixedly mounted on the base, and the first baffle extends along the circumferential direction of the base to the inner wall of the grinding head, so that the base is fixedly connected to the grinding head; the lower end of the first baffle abuts against the mother grinding head to play a role of protection and limiting. Through the above arrangement, the grinding head, the base and the mother grinding head can form a synchronously rotating whole; the function of the first baffle is to block the unground seasoning, ensuring that the seasoning can only be scattered to the outside through the grinding channel.

[0011] Preferably, a mounting portion is provided at the upper portion of the socket, and a second baffle is installed on the mounting portion; the second baffle is annular with a slope, the inner ring of the second baffle is arranged along the inner wall of the mounting portion, and the outer ring of the second baffle is fixedly connected to the grinding head; the side wall of the support frame abuts against the lower end of the second baffle. In this arrangement, the support frame can be axially limited by the second baffle to prevent the support frame from being separated from the plug when the grinder is inverted.

[0012] Preferably, the outer wall of the plug is provided with an annular groove, and the inner wall of the socket is provided with an ejection card module, and the ejection card module partially extends into the annular groove. Through the above arrangement, when the user presses the grinding head, the ejection card module will be squeezed and forced to deform, thereby ensuring smooth plugging; when the ejection card module reaches the position of the annular groove, the squeezing force on the ejection card module disappears, and then the ejection card module recovers under its own elastic force, so that the ejection card module partially extends into the annular groove for engagement; in addition, the grinding head and the tank body can rotate relative to each other under the limited cooperation of the ejection card module and the annular groove.

[0013] Preferably, the number of the spring card modules is at least two, and the spring card modules are evenly distributed along the circumferential direction of the socket. Such a configuration can balance the forces on each spring card module, thereby making the connection between the grinding head and the tank body more stable.

[0014] Preferably, the snap-on module is a pin, the number of the pins is four, and the head of the pin is arc-shaped, so that the grinding head can be quickly plugged into the tank. With this arrangement, the connection between the tank and the grinding head can be further stabilized through multiple snap-on points, so that the grinding head is not prone to tilting; in addition, the difficulty of installing the grinding head and the tank is reduced, and the user only needs to press lightly to complete the installation.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] The tank body and the support frame are rotated and limited by mutually adapted polygons. When the support frame is damaged, the support frame can be replaced separately. The support frame can be made into a universal accessory separately, which effectively reduces the replacement cost of users. The relative position between the male grinding head and the female grinding head can be controlled by twisting the adjustment piece, and then the grinding accuracy of the grinder can be adjusted according to actual needs. The limit block and the male grinding head can effectively reduce the stress on the male grinding head through the limit fit of the teeth and the teeth, thereby increasing the service life of the male grinding head.

[0017] The pin has elastic expansion and contraction capabilities. After being squeezed by the plug, the pin shrinks, and then recovers and engages in the groove, so that the grinding head is limitedly installed on the tank body; when the grinding head is pulled up, the plug can squeeze the pin again to shrink it, so that the grinding head is separated from the tank body; the grinding head and the tank body can be quickly plugged in and out.

DETAILED DESCRIPTION

[0025] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0029] One aspect of the present application provides a grinder, such as Figure 1 , Figure 2 and Figure 3 As shown, one preferred embodiment includes a grinding head 1 and a tank body 2, a grinding assembly 3 is installed inside the grinding head 1, and the grinding head 1 is connected to the tank body 2 to ensure that the seasoning can be transferred from the tank body 2 to the grinding head 1 for grinding. The grinding assembly 3 includes a male grinding head 31 and a female grinding head 32, and the male grinding head 31 and the female grinding head 32 are plugged to form a grinding channel 100 for grinding seasoning. The grinding channel 100 is formed by the inner wall of the female grinding head 32 and the outer wall of the male grinding head 31, and the width of the grinding channel 100 decreases from top to bottom. After the grinder is inverted, the seasoning enters the grinding channel 100 through the lower part of the grinding assembly 3, and then is ground into powder under the extrusion force formed by the relative rotation of the male grinding head 31 and the female grinding head 32. When the seasoning is ground to a specific fineness, it can pass through the grinding channel 100 and be sprinkled to the outside.

[0030] Further, such as Figure 1 As shown, a plug 21 is provided at the upper part of the tank body 2, and a socket 11 is provided at the lower part of the grinding head 1, and the plug 21 is plugged into the socket 11; so that the grinding head 1 is installed above the tank body 2. A support frame 4 for limiting the male grinding head 31 is installed in the grinding head 1, and the lower part of the support frame 4 can be plugged into the plug 21, so that there is no relative rotation between the male grinding head 31 and the tank body 2. A base 12 is rotatably installed on the support frame 4, and the female grinding head 32 is limitedly installed on the base 12; the base 12 is used to drive the female grinding head 32 to rotate.

[0031] It should be added that in order to ensure that the base 12 does not deviate from the support frame 4 during rotation, a mutually cooperating rail structure can be provided on the base 12 and the support rod 4, and the limiting cooperation of the rail structure can ensure that the rotation plane of the base 12 will not be offset.

[0032] In this embodiment, if Figure 4 As shown, the inner wall of the plug 21 is polygonal, and the outer wall of the support frame 4 is provided with a polygon that matches the inner wall of the socket 11. After the support frame 4 is installed in the socket 11, the polygonal limiting fit can be used to ensure that no relative rotation occurs between the support frame 4 and the tank body 2.

[0033] It is understandable that the support frame 4 needs to provide support for the male grinding head 31 at all times, and it is easy to wear out under long-term use, thereby affecting the normal use of the grinder; however, in the present application, the support frame 4 is designed as a universal component, and when the support frame 4 is damaged, it can be replaced separately, which effectively saves the user's purchase cost.

[0034] Specifically, Figure 1 and Figure 5As shown, a support rod 41 is provided on the support frame 4, and the cross-section of the support rod 41 is a polygon; a limit block 42 is installed on the support rod 41, and the limit block 42 is provided with a perforation 420 that is adapted to the cross-section of the support rod 41. The support rod 41 is inserted into the perforation 420 and the polygonal limit fit ensures that the limit block 42 and the support rod 41 will not rotate relative to each other, thereby ensuring that the limit block 42 and the tank body 2 will not rotate relative to each other.

[0035] Further, such as Figure 1 and Figure 6 As shown, the longitudinal cross-section of the limit block 42 is in a "T" shape, and a through hole 310 is provided on the male grinding head 31, and the lower part of the limit block 42 is plugged into the through hole 310; in order to ensure that the male grinding head 31 can rotate relative to the female grinding head 32, it is necessary to ensure that the male grinding head 31 and the tank body 2 do not rotate relative to each other; however, since the material of the male grinding head 31 is ceramic, if the male grinding head 31 is directly fixedly connected to the tank body 2, the stress on the male grinding head 31 may be large during the grinding process, resulting in damage. Therefore, in the present application, mutually cooperating latch teeth 401 and latch grooves 402 are provided on the fitting surfaces of the limit block 42 and the male grinding head 31 for limiting, and the latch teeth 401 can unload the force through a certain degree of deformation, effectively reducing the probability of damage to the male grinding head 31.

[0036] It is understandable that, in order to further reduce the stress on the male grinding head 31 , one side of the latching tooth 401 and the latching groove 402 may be set as an inclined surface to ensure that the latching tooth 401 has a larger deformation space to release the stress.

[0037] In this embodiment, if Figure 1 and Figure 4 As shown, an adjusting member 300 is installed on one end of the support rod 41 away from the support frame 4, and the adjusting member 300 and the support rod 41 are connected by threaded fit. A spring is installed between the male grinding head 31 and the support frame 4, and the male grinding head 31 pushes the limit block 42 to abut against the adjusting member under the elastic drive of the spring. Since the position of the female grinding head 32 will not change, the height of the male grinding head 31 can be adjusted by twisting the adjusting member 300, thereby changing the relative position of the male grinding head 31 and the female grinding head 32. When the positions of the male grinding head 31 and the female grinding head 32 change, the size of the grinding channel 100 formed by the male grinding head 31 and the female grinding head 32 will also change. The smaller the grinding channel 100, the higher the precision of the grinder; therefore, the grinding precision of the grinder can be adjusted by the adjusting member 300.

[0038] It should be noted that the adjusting member 300 not only changes the relative position of the male grinding head 31 and the female grinding head 32 , but also takes into account the disassembly and installation of the grinder. The parts inside the grinding head 1 can be disassembled only after the adjusting member 300 is removed.

[0039] Specifically, Figure 1 As shown, a first baffle 200 is fixedly installed on the upper part of the base 12, and the first baffle 200 extends along the circumferential direction of the base 12 to the inner wall of the grinding head 1, so that the base 12 is fixedly connected to the grinding head 1. In order to enable the female grinding head 32 and the male grinding head 31 to rotate relative to each other, the female grinding head 32 is limitedly installed on the base 12, and the outer wall of the female grinding head 32 is provided with a protrusion, and the inner wall of the base 12 is provided with a groove. The female grinding head 32 is embedded in the base 12, and the protrusion and the groove are limited to cooperate, so that the female grinding head 32 can rotate synchronously with the base 12. In addition, the first baffle 200 can also block unground seasonings, ensuring that the seasonings can only be scattered to the outside through the grinding channel 100.

[0040] It is understandable that the connection between the female grinding head 32 and the base 12 is designed to be detachable, which facilitates the subsequent cleaning and replacement of the female grinding head 32. At the same time, in order to ensure that the female grinding head 32 does not fall off from the base 12, the lower end of the first baffle 200 should be against the female grinding head 32 to limit the female grinding head 32 in the vertical direction.

[0041] In this embodiment, if Figure 1 and Figure 2 As shown, a mounting portion 111 is provided at the upper portion of the socket 11, and a second baffle 201 is installed on the mounting portion 111. The second baffle 201 is inclined to the cross-section of the grinding head 1, and the higher side of the second baffle 201 is arranged along the inner wall of the grinding head 1. The side wall of the support frame 4 abuts against the lower end of the second baffle 201, further limiting the insertion depth of the plug 21 on the socket 11, and also limiting the support frame 4 in the vertical direction.

[0042] In this embodiment, if Figure 1 and Figure 2 As shown, in order to further optimize the convenience of plugging the grinding head 1 into the tank body 2, a plug 21 is provided on the upper part of the tank body 2, and a plug 21 is provided on the lower part of the grinding head 1. The grinding head 1 and the tank body 2 can be connected by inserting the plug 21 into the socket 11.

[0043] It should be known that in the prior art, the grinding head 1 and the tank body 2 are connected by matching threads. Although the connection stability is relatively strong, it is still troublesome in installation and disassembly, and it is easy to be misaligned, tilted, etc., causing the seasoning to spill out from the connection between the tank body 2 and the grinding head 1.

[0044] In view of the above situation, in this embodiment, if Figure 2As shown, the outer wall of the plug 21 is provided with an annular groove 210, and the inner wall of the socket 11 is provided with an elastic card module capable of elastic deformation, and the card module is rotatably installed in the annular groove 210, so that the grinding head 1 can rotate relative to the tank body 2, avoiding the need to set a rotating component on the grinding head 1 alone, and further simplifying the structure of the grinder. When the user presses the grinding head 1, the card module will be squeezed and forced to deform, thereby ensuring smooth insertion; when the card module reaches the position of the annular groove 201, the squeezing force on the card module disappears, and then the card module recovers under its own elastic force, so that the card module partially extends into the annular groove 210 for engagement.

[0045] It is understandable that in order to further improve the connection stability between the grinding head 1 and the tank body 2, the number of the pin card modules is at least two, and the pin card modules are evenly distributed along the circumferential direction of the socket 11; thereby the forces on each pin card module are balanced.

[0046] Further, such as Figure 2 As shown, the ejection module is a pin 100, and the number of the pins 100 is four. The head of the pin 100 is arc-shaped, so that the plug 21 can slide on the arc surface of the pin 100, which effectively reduces the difficulty of the plug 21 compressing the pin 100. When the user wants to remove the grinding head 1 from the tank body 2, the grinding head 1 can be pulled up to drive the pin 110 to squeeze the plug 21, and then the arc surface of the plug 21 and the pin 110 are displaced relative to each other, thereby forcing the pin 110 to shrink to complete the removal.

[0047] It is understandable that the uniform support of the four pins 110 can further improve the stability of the connection between the grinding head 1 and the tank body 2 to ensure that the grinding head 1 will not tilt when it is hit by an external force.

[0048] Specifically, Figure 2 As shown, the outer wall of the plug 21 is provided with a chamfer. When the plug 21 is plugged into the socket 11, the pin 110 first contacts the chamfered surface on the plug 21, further reducing the difficulty of squeezing the pin 110. The user only needs to press lightly to complete the installation of the grinding head 1 and the tank body 2.

[0049] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
