Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of coffee, in particular to an adjustable coffee powder press and a coffee device. BACKGROUND

[0002] At present, with the continuous rise of coffee culture, people's demand for coffee is also increasing. However, the bulkiness of coffee powder directly affects the taste of coffee. Therefore, it is necessary to compact the coffee powder when brewing coffee, so as to change the bulkiness of the coffee powder. In view of this, a coffee powder press is designed to meet this demand on the market.

[0003] For example, Chinese patent document CN220832787U discloses a coffee powder press, which comprises a handle, a fixed cylinder, a movable cylinder, a pressure adjusting spring, a middle shaft and a pressing assembly. The bottom of the handle is provided with a strip-shaped cavity along the axial direction thereof. The movable cylinder, the fixed cylinder and the pressure adjusting spring are all arranged in the strip-shaped cavity, and the pressure adjusting spring is arranged between the fixed cylinder and the movable cylinder. The fixed cylinder and the movable cylinder are both hollow structures. The middle shaft comprises a rotating part and a limiting part. The fixed cylinder is sleeved on the rotating part, and the movable cylinder is sleeved on the limiting part.

[0004] However, the design of the above-mentioned coffee powder press has the following problems:

[0005] Although the above-mentioned coffee powder press makes the rotating part rotate relative to the fixed cylinder through the middle shaft, and then makes the limiting part drive the movable part to rotate to make the movable part approach or move away from the fixed sleeve, when the movable part approaches the fixed sleeve to press coffee powder through the limiting part, the operator may cause the fixed sleeve to be pressed too deeply due to excessive rotation force, which cannot guarantee the consistency of the pressing force each time, thereby causing the coffee powder to be pressed too tightly or loosely. When the coffee powder is pressed too tightly or loosely, the brewed coffee liquid will be too light or bitter, thereby affecting the flavor and taste of the coffee. UTILITY MODEL CONTENT

[0006] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide an adjustable coffee powder press and a coffee device which can conveniently adjust the pressing depth.

[0007] The purpose of the present disclosure is achieved by the following technical solutions:

[0030] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0031] like Figure 1 As shown, an adjustable powder presser 10 according to one embodiment includes a pressing cover 100, an adjusting component 200, a powder pressing block 300, and a connecting rod 400;

[0032] The first end of the connecting rod 400 is connected to the pressing cover 100, and the second end of the connecting rod 400 is connected to the powder pressing block 300. The adjusting component 200 is slidably disposed on the inner peripheral wall of the pressing cover 100. The adjusting component 200 has a telescopic sliding cavity 210, and the connecting rod 400 passes through the telescopic sliding cavity 210. The adjusting component 200 is used to adjust the pressing and lowering stroke of the pressing cover 100. When the pressing cover 100 moves to a predetermined position relative to the telescopic sliding cavity 210 with the connecting rod 400, the pressing cover 100 abuts against the end face of the adjusting component 200.

[0033] It can be understood that by adjusting the assembly 200 to open the telescopic sliding cavity 210, the connecting rod 400 is arranged in the telescopic sliding cavity 210, and the first end of the connecting rod 400 is connected to the pressing cover 100, and the second end of the connecting rod 400 is connected to the powder pressing block 300. Because the adjusting assembly 200 is slidably arranged on the inner circumferential wall of the pressing cover 100, when powder pressing is needed, the pressing cover 100 is pressed downward, and the pressing cover 100 drives the powder pressing block 300 connected with the connecting rod 400 to move downward. Because the adjusting assembly 200 is located between the pressing cover 100 and the powder pressing block 300, the bottom of the pressing cover 100 abuts against the end face of the adjusting assembly 200, so that the pressing cover 100 completes the powder pressing operation. Because the adjusting assembly 200 is slidably arranged on the inner circumferential wall of the pressing cover 100, the distance between the pressing cover 100 and the adjusting assembly 200 can be changed by sliding. The distance between the pressing cover 100 and the adjusting assembly 200 is the distance of the powder pressing depth of the powder pressing block 300, so that the powder pressing depth of the adjustable powder pressing device 10 can be changed at will, and different powder pressing depths can be changed according to different coffee powder. The situation that the powder pressing depth of the powder pressing block 300 is too much due to excessive force is avoided, and the powder pressing depth of the powder pressing block 300 is accurately controlled.

[0034] In combination Figure 1 With Figure 2 As shown in the drawings, in one embodiment, the adjusting assembly 200 includes a rotating adjusting ring 220 and a fixed seat 230. The rotating adjusting ring 220 is movably connected to the fixed seat 230. The telescopic sliding cavity 210 is arranged in the fixed seat 230. The bottom of the fixed seat 230 is provided with a containing cavity 2310. The powder pressing block 300 passes through the containing cavity 2310 and is connected to the connecting rod 400. It can be understood that the rotating adjusting ring 220 is slidably arranged on the inner circumferential wall of the pressing cover 100. When the rotating adjusting ring 220 is rotated, the rotating adjusting ring 220 slides up and down along the inner circumferential wall of the pressing cover 100, so that the distance between the pressing cover 100 and the rotating adjusting ring 220 changes. At the same time, the powder pressing block 300 passes through the containing cavity 2310 and is connected to the connecting rod 400. When the pressing cover 100 is pressed downward, because the two ends of the connecting rod 400 are connected to the pressing cover 100 and the powder pressing block 300, and the connecting rod 400 passes through the telescopic sliding cavity 210, the powder pressing block 300 can complete the powder pressing operation along with the movement track of the pressing cover 100. The rotating adjusting ring 220 is movably connected to the fixed seat 230, so that the rotating adjusting ring 220 and the fixed seat 230 can be replaced by disassembly.

[0035] In combination Figure 1 With Figure 2As shown, in one embodiment, the adjustable powder press 10 further comprises a fixed coil 500, and a groove 2320 is formed in the outer circumferential wall of the fixed seat 230, and the fixed coil 500 is sleeved on the groove 2320 and tightly attached to the rotating adjusting ring 220. It can be understood that the groove 2320 is formed in the outer circumferential wall of the fixed seat 230, and the fixed coil 500 is sleeved on the groove 2320 and tightly attached to the outer circumferential wall of the rotating adjusting ring 220. When the fixed seat 230 and the rotating adjusting ring 220 are assembled together, the fixed coil 500 is sleeved on the groove 2320 of the fixed seat 230 and tightly attached to the outer circumferential wall of the rotating adjusting ring 220. When the fixed seat 230 and the rotating adjusting ring 220 are assembled together, the rotating adjusting ring 220 can be stably rotated during the operation of the rotating adjusting ring 220, and the shaking of the rotating adjusting ring 220 and the fixed seat 230 during the operation is avoided.

[0036] As shown, Figure 1 With Figure 2 As shown, in another embodiment, the rotating adjusting ring 220 is slidingly arranged on the inner circumferential wall of the pressing cover 100. It can be understood that the rotating adjusting ring 220 is slidingly arranged on the inner circumferential wall of the pressing cover 100. The pressing distance of the pressing cover 100 can be changed by adjusting the distance between the rotating adjusting ring 220 and the pressing cover 100, so as to change the powder pressing depth of the powder pressing block 300.

[0037] In combination with Figure 1 With Figure 2 As shown, in one embodiment, the adjustable powder press 10 further comprises an elastic reset member 600, which is arranged in the telescopic sliding cavity 210 and sleeved on the connecting rod 400. One end of the elastic reset member 600 abuts against the fixed seat 230, and the other end of the elastic reset member 600 abuts against the inner cavity of the fixed seat 230. It can be understood that the elastic reset member 600 is arranged in the telescopic sliding cavity 210 and sleeved on the connecting rod 400, and one end of the elastic reset member 600 abuts against the inner cavity of the pressing cover 100, and the other end of the elastic reset member 600 abuts against the fixed seat 230. When the pressing cover 100 is lowered, because the two ends of the elastic reset member 600 abut against the inner cavity of the pressing cover 100 and the fixed seat 230 respectively, the elastic reset member 600 will be compressed according to the elasticity. When the pressing cover 100 releases the pressure, because the elasticity of the elastic reset member 600 will make the pressing cover 100 and the powder pressing block 300 return to the original position. Arranging the elastic reset member 600 in the telescopic sliding cavity 210 is beneficial to the resetting function of the pressing cover 100 and the powder pressing block 300 after the powder pressing operation is completed. The elastic reset member 600 in the embodiment can be a spiral spring or an elastic spring.

[0038] In combination with Figure 2 With Figure 3As shown, in one embodiment, the outer periphery of the rotating adjusting ring 220 is provided with a limiting boss 2210, and the bottom of the pressing cover 100 is provided with an abutment portion 110. When the pressing cover 100 moves to a predetermined position relative to the telescopic sliding cavity 210 with the connecting rod 400, the abutment portion 110 abuts against the end face of the limiting boss 2210. It can be understood that with the limiting boss 2210 protruding from the outer periphery of the rotating adjusting ring 220 and the abutment portion 110 at the bottom of the pressing cover 100, when the pressing cover 100 descends to the predetermined position relative to the telescopic sliding cavity 210, the abutment portion 110 abuts against the end face of the limiting boss 2210, thereby controlling the pressing depth of the powder pressing block 300.

[0039] like Figure 2 As shown, in another embodiment, the outer peripheral wall of the rotating adjustment ring 220 is provided with scale lines 2220, the length direction of which is the same as the pressing direction of the pressing cover 100. It can be understood that having scale lines 2220 on the outer peripheral wall of the rotating adjustment ring 220, and the scale lines 2220 having the same length direction as the pressing direction of the pressing cover 100, facilitates observation of the distance the pressing cover 100 descends, allowing operators to adjust the pressing depth of the powder pressing block 300 according to different needs.

[0040] Combination Figure 1 and Figure 2 In one embodiment, the first end of the connecting rod 400 is detachably connected to the pressing cover 100, and the second end of the connecting rod 400 is detachably connected to the powder pressing block 300. It is understood that the detachable design at both ends of the connecting rod 400 facilitates maintenance and replacement, improving the flexibility and durability of the mechanism. When it is necessary to adjust or replace the pressing cover 100 and the powder pressing block 300, the operation can be quickly completed by simply disassembling the connecting rod 400, ensuring the long-term stable operation of the powder pressing mechanism.

[0041] Combination Figure 1 and Figure 2Further, the powder pressing block 300 is provided with a threaded convex head 310, one end of the connecting rod 400 is provided with a connecting cavity 410, the other end of the connecting rod 400 is provided with a threaded connecting portion 420, the threaded convex head 310 is threadedly connected to the connecting cavity 410, and the threaded connecting portion 420 is threadedly connected to the inner cavity of the pressing cap 100. It can be understood that the threaded convex head 310 is threadedly connected to the connecting cavity 410, so that the powder pressing block 300 is threadedly connected to one end of the connecting rod 400, and the other end of the connecting rod 400 is provided with the threaded connecting portion 420, which is threadedly connected to the inner cavity of the pressing cap 100, so that the connecting rod 400 threadedly connects the pressing cap 100 and the powder pressing block 300 together, and the pressing cap 100 and the powder pressing block 300 are stably connected to both ends of the connecting rod 400 through the threaded connection.

[0042] In combination Figure 1 With Figure 2 As shown in one of the embodiments, the rotating adjusting ring 220 is sleeved on the fixing seat 230 and is threadedly connected with the fixing seat 230. It can be understood that the rotating adjusting ring 220 is sleeved on the fixing seat 230 and is threadedly connected with the fixing seat 230, so that the rotating adjusting ring 220 is sleeved on the fixing seat 230 through the threaded connection. When the pressing cap 100 is pressed down, because the rotating adjusting ring 220 is threadedly connected with the fixing seat 230, they are not easy to shake and deviate, which ensures that the powder pressing block 300 is consistent with the vertical direction of the connecting rod 400.

[0043] In combination Figure 1 With Figure 2 As shown in one of the embodiments, the outer peripheral wall of the fixing seat 230 is provided with an outer thread 2330, the cavity wall of the rotating adjusting ring 220 is provided with an inner thread 2230, and the outer thread 2330 is connected with the inner thread 2230. It can be understood that the outer thread 2330 is arranged on the outer peripheral wall of the fixing seat 230, and the inner thread 2230 is arranged on the cavity wall of the rotating adjusting ring 220. Through the matched connection of the outer thread 2330 and the inner thread 2230, the rotating adjusting ring 220 and the fixing seat 230 are stably connected together. When the pressing cap 100 abuts on the end face of the rotating adjusting ring 220, the loosening or displacement of the rotating adjusting ring 220 and the fixing seat 230 caused by the impact force of the pressing cap 100 is avoided, which ensures the stability and accuracy of the powder pressing operation.

[0044] As Figure 1 With Figure 3As shown, the application also provides a coffee device comprising the adjustable powder presser 10 of any of the above embodiments. It can be understood that when the pressing cover 100 moves downward, the pressing cover 100 drives the powder pressing block 300 connected with the connecting rod 400 to move downward, and because the adjusting assembly 200 is located between the pressing cover 100 and the powder pressing block 300, the bottom of the pressing cover 100 abuts against the end face of the adjusting assembly 200, so that the pressing cover 100 completes the powder pressing operation. Because the adjusting assembly 200 is slidably arranged on the inner peripheral wall of the pressing cover 100, the distance between the pressing cover 100 and the adjusting assembly 200 can be changed by sliding, so that the powder pressing depth of the adjustable powder presser 10 can be changed at will.

[0045] Compared with the prior art, the present disclosure has at least the following advantages:

[0046] By opening the telescopic sliding cavity 210 in the adjusting assembly 200, the connecting rod 400 is arranged in the telescopic sliding cavity 210, and the first end of the connecting rod 400 is connected to the pressing cover 100, and the second end of the connecting rod 400 is connected to the powder pressing block 300. Because the adjusting assembly 200 is slidably arranged on the inner peripheral wall of the pressing cover 100, when the pressing cover 100 is pressed and moved downward, the pressing cover 100 drives the powder pressing block 300 connected with the connecting rod 400 to move downward, and because the adjusting assembly 200 is located between the pressing cover 100 and the powder pressing block 300, the bottom of the pressing cover 100 abuts against the end face of the adjusting assembly 200, so that the pressing cover 100 completes the powder pressing operation. Because the adjusting assembly 200 is slidably arranged on the inner peripheral wall of the pressing cover 100, the distance between the pressing cover 100 and the adjusting assembly 200 can be changed by sliding, so that the powder pressing depth of the adjustable powder presser 10 can be changed at will. Different powder pressing depths can be changed according to different coffee powder, avoiding the case that the powder pressing depth of the powder pressing block 300 is too much because of excessive force, and realizing accurate control of the powder pressing depth of the powder pressing block 300.

[0047] The above-described embodiments only express several embodiments of the present disclosure, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, a number of modifications and improvements can be made, which are within the protection scope of the present disclosure.
