Description

Technical Field

[0001] The invention relates to the technical field of daily necessities, and in particular to a powder grinder. Background Art

[0002] Nowadays, depending on the different ways of using condiments, more people will choose to use powdered condiments. The powdered condiments sold on the market are all finished products and products processed by machines. After being crushed and exposed to the air, they can hardly guarantee the original flavor of the condiments themselves to a large extent, and the eating effect is not good. Therefore, most people now use the method of fresh grinding. However, there are not many household fresh grinding tools, and electric grinders are not fine enough for grinding condiments.

[0003] There are also instruments that use manual grinding, such as a grinder in a Chinese utility model patent with a publication number of CN200970158 and a publication date of November 7, 2007, which particularly discloses a condiment grinder. The condiment grinder includes a fixed grinder fixed to a bottle body by a thread, a dynamic grinder positioned on the fixed grinder, and a transparent upper cover buckled on the dynamic grinder. The special feature of the grinder is that the connection between the dynamic grinder and the fixed grinder is a concave-convex groove, the inner ring of the fixed grinder is provided with a toothed disc, and the lower part of the dynamic grinder is fixed with a toothed pin that matches the toothed disc. The toothed pin is provided with an adjustment buckle that gradually tapers from top to bottom. The utility model has the characteristics of reasonable design, simple structure, convenient and flexible operation, and adjustable thickness.

[0004] Although the above structure can realize the grinding of condiments, its upper and lower separated structure is unstable, and the grinding particle size is not fixed. If the particles are too large during the grinding process, it will cause the structure to separate, the gap will become larger, and the grinding particle size will also become larger. At this time, it is necessary to squeeze and grind with force, and the purpose of the adjustment buckle is only to filter the particle size process, and it cannot control the size of the desired grinding particle size. It can only be repeatedly ground and then checked to see if the particle size is the desired particle size, which is time-consuming and laborious, and it is impossible to accurately obtain the desired particle size.

[0005] In addition, traditional grinders also use a particle size adjustment structure, and its adjustment size is adjusted through a fine thread + spring structure.

DETAILED DESCRIPTION

[0042] The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0043] like Figure 1 , Figure 2 As shown, it shows a powder grinder provided by an embodiment of the present invention, comprising a bottle body 1, a grinding device is provided at the bottle mouth of the bottle body 1, the grinding device comprises a rotating member 2 which is rotatably engaged at the bottle mouth of the bottle body 1, the rotating member 2 is riveted to the bottle mouth, an inner core 3 and an outer core 4 which cooperate with each other are provided inside the rotating member 2, a grinding structure 9 which cooperates with each other is provided on the outer wall of the inner core 3 and the inner wall of the outer core 4, wherein the grinding structure 9 is a concave-convex threaded structure which is axially spiral, and the inner core 3 is provided on the bottle body 1 The inner core fixing part 5 inside the bottle mouth is supported, and the outer core 4 is supported by the outer core fixing part 6 arranged above the inner core fixing part 5. The top of the rotating part 2 is provided with an adjusting part 7 engaged with the inner core fixing part 5. The rotating part 2 and the adjusting part 7 are worm geared. The strip opening at the bottom of the adjusting part 7 is fixedly buckled with the outer core fixing part 6. The outer edge of the inner core fixing part 5 is placed on the bottle mouth of the bottle body 1. The rotating part 2 presses the inner core fixing part 5. The top of the adjusting part 7 is provided with a dust cover 8, and the outer surface of the dust cover 8 can be provided with different patterns as decoration.

[0044] Among them, the inner core fixing part 5 stably fixes the inner core 3, the bottom of the adjusting part is engaged with the outer core fixing part 6, the top of the adjusting part is fixedly engaged with the rotating part 2, and the dust cover 8 is buckled on the top of the adjusting part. When in use, it is only necessary to rotate the rotating part 2, and the rotating part 2 drives the outer core fixing part 6 through the adjusting part, so that the outer core 4 and the inner core rotate relative to each other to achieve material grinding. The rotating part 2 and the bottle body 1 are riveted to each other, so that they are tightly fixed, the inner core 3 and the outer core 4 are overlapped, the structure is compact, the components are closely matched, the grinding effect is good, and the operation is convenient.

[0045] like Figure 3 , Figure 4As shown, the rotating member 2 includes a main body ring 201, and the inner wall of the bottom of the main body ring 201 is provided with a riveted structure that can be buckled with the bottle mouth of the bottle body 1, and the inner wall of the main body ring 201 is provided with an upper limit isolation plate 202, a support plate 203, a gear adjustment block 204 and a shift paddle 205. The support plate 203 is arranged on the lower side of the upper limit isolation plate 202, and the gear adjustment block 204 and the shift paddle 205 are arranged at the edge of the upper limit isolation plate 202.

[0046] Specifically, the gear adjustment block 204 and the shift paddle 205 are located at adjacent positions on the same horizontal plane, and a gear marking line 206 is provided on the outer wall of the main ring 201. The gear marking line 206 is used to determine the adjustment direction of the grinding particle size and confirm the grinding particle size more intuitively.

[0047] like Figure 5 As shown, the inner core 3 is a fixed block with an inverted cone structure, with a socket 301 in the middle position thereof, and the outer core 4 is a movable part that can be placed inside the outer core fixing part 6. The interior of the outer core 4 has a cavity for placing the inner core 3, and a convex rib 401 is provided on the outer wall of the outer core 4.

[0048] like Figure 6 , Figure 7 , Figure 8 As shown, and see Fig.16 The inner core fixing member 5 includes a fixing ring 501, and an arc-shaped support plate 502 is arranged inside the fixing ring 501. The purpose of adopting the arc-shaped design is to prevent the particles ground into powder from being deposited here. A plug-in 503 that can be plugged into the socket 301 is arranged on the support plate 502. The plug-in 503 and the socket are anti-rotation structures, specifically square locking. The fixing ring 501 can be buckled at the bottle mouth of the bottle body 1. A notch 504 is arranged on the outer edge of the fixing ring 501, and the notch 504 can be stuck on the protrusion 101 provided on the bottle mouth of the bottle body 1.

[0049] like Fig. 9 , Fig.10 As shown, the outer core fixing member 6 includes a ring body 601, the top of the ring body 601 is provided with a buckle 602 that can be clamped on the adjustment member 7, and the inner wall of the ring body 601 is provided with a key groove 603 for the convex rib 401 on the outer core 4 to engage with. The key groove 603 engaged with the convex rib 401 is fixed in cooperation, which is conducive to driving the outer core 4 to rotate.

[0050] like Fig.11 , Fig.12 , Fig.13 , Fig.14The adjusting member 7 is a ring cover structure buckled on the rotating member 2, including an integrated upper ring 701 and a lower ring 702. The lower ring 702 is placed inside the rotating member 2. The lower ring 702 is provided with a bar hole 703 corresponding to the buckle 602 and for its engagement. The outer wall of the lower ring 702 is provided with a gear adjustment interval belt 704 for the gear adjustment block 204 to move. The gear adjustment interval belt 704 is inclined, and a gear feedback line 705 is provided on the side of the gear adjustment interval belt 704.

[0051] The bar hole 703 at the bottom of the adjusting part 7 is riveted with the buckle 602 on the outer core fixing part 6, and then the upper limit isolation plate 202 on the inner wall of the rotating part 2 limits the upper limit position of the outer core fixing part 6, and finally the adjusting part 7, the rotating part 2 and the outer core fixing part 6 can restrain each other to achieve a stable effect.

[0052] Specifically, the gear feedback line 705 is in sliding contact with the shift paddle 205, which is rotated and moved to confirm the gear change.

[0053] More specifically, a particle size mark 706 and an anti-slip structure 707 are provided on the outer wall of the upper ring 701. The particle size mark 706 is used to confirm the particle size that needs to be ground. The number of particle size classifications of the particle size mark 706 is the same as the number of gear feedback lines 705, and the direction is the same, that is, the direction of the gear adjustment range band 704 from the highest position to the lowest position and the particle size classification of the particle size mark 706 are from small to large.

[0054] When in use, the gear adjustment block 204 is placed at the lowest position of the gear adjustment interval band 704. At this time, the grinding particle size is the largest. According to the structure shown in the figure, the adjustment part 7 is rotated clockwise, and the gear adjustment block 204 slides from the low position to the high position of the gear adjustment interval band 704. At the same time, the shift paddle 205 contacts and slides with the gear feedback line 705. When it passes through one of the gear feedback lines 705, a sound is made, which proves that the gear with the desired grinding particle size has been entered. The operation is convenient and more intuitive.

[0055] The upper limit isolation plate 202 in the rotating member 2 can prevent the outer core fixing member 6 from infinitely moving upward, and plays a role of limiting, thereby preventing the gear adjustment block 204 from breaking due to excessive rotation.

[0056] The change in grinding particle size actually occurs when the adjusting member 7 rotates, which drives the outer core fixing member 6 to move upward or downward, thereby moving the outer core 4 upward or downward, while the position of the inner core 3 remains unchanged. In fact, it is the gap between the outer core 4 and the inner core 3 that changes, thereby changing the grinding particle size.

[0057] like Fig.15 , Fig.18As shown, a freely rotatable discharge ring 10 is provided at the bottle mouth of the bottle body 1, and the discharge ring 10 is arranged on the bottom side of the grinding device. A discharge port 11 is provided at the position of the discharge ring 10 and the bottle body 1 covered by it, that is, a discharge port 11 is provided at the position of the bottle mouth covered by the discharge ring 10, and the discharge ring 10 can rotate freely. When the original particles are needed, it is only necessary to rotate the discharge ring 10 and match the two discharge ports 11, so as to take out the original particles, which is convenient to use.

[0058] In this embodiment, Fig.16 , Fig.17 , Fig.19 As shown, a positioning rib 102 is provided on the other side of the bottle mouth of the bottle body 1 opposite to the discharge port 11, and a positioning groove 12 is provided on the inner side of the discharge ring 10 to cooperate with the positioning rib 102. When it is used, when the discharge ring 10 is rotated, when the positioning rib 102 is rotated to the positioning groove 12 to be fixed, the bottle body 1 and the discharge port 11 on the discharge ring 10 are concentric.

[0059] Specifically, the mouth of the bottle body 1 is an upper and lower fixed structure, the protrusion 101 is arranged on the outer wall of the upper structure, and is fixed with the groove 504 provided on the outer edge of the fixing ring 501, and the positioning rib 102 is arranged on the outer wall of the lower structure of the mouth of the bottle body 1, and the discharge ring 10 is sleeved on the lower structure of the mouth of the bottle, wherein the discharge port 11 on the discharge ring 10 is wide-mouthed, gradually expanding from the inside to the outside, which can ensure that the granular material is poured out smoothly and avoid getting the discharge ring 10 stuck.

[0060] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
