Description

Technical Field

[0001] This disclosure relates to the technical field of adjustable coffee bean grinders, and in particular to a reset adjustment structure and an adjustable coffee bean grinder. Background Technology

[0002] In related technologies, most coffee grinders with particle size adjustment functions rely on adjusting the height of the grinding element to change the grinding gap, thereby adjusting the coarseness of the coffee powder. This mechanism is generally achieved through the relative movement between the lifting structure and the machine body, where the rising or falling of the lifting structure directly moves the grinding element accordingly. Currently, many manufacturers in the market prefer to use servo motors as the drive source because they can precisely control the displacement of the lifting structure, ensuring the fineness of the grinding gap adjustment and thus meeting users' different needs for the fineness of the coffee powder.

[0003] However, it is an undeniable fact that servo motors are not only more technically complex than traditional motors, but also significantly more expensive in terms of procurement and integration. This cost difference is directly passed on to the final selling price of coffee grinders, resulting in higher production costs for coffee grinders using servo motors. Utility Model Content

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0028] like Figures 1 to 4 As shown, in one embodiment, a reset adjustment structure 100 is installed inside the grinder body 200 of an adjustable coarseness coffee bean grinder 10. It includes a transmission adjustment assembly 110, a transmission motor 120, and a reset assembly 130. The mounting end of the transmission adjustment assembly 110 is fixedly installed inside the grinder body 200, and the adjustment end of the transmission adjustment assembly 110 is connected to the grinder component 300 of the grinder body 200 for rotational limiting. The fixing end of the transmission motor 120 is fixedly installed on the grinder body 200. The drive end of the motor 120 is installed inside the grinder body 200 and is connected to the adjustment end of the transmission adjustment component 110 to drive the adjustment end of the transmission adjustment component 110 to rise or fall relative to the mounting end of the transmission adjustment component 110. This allows the motor 120 to drive the adjustment end of the transmission adjustment component 110 to rise from its initial position relative to the grinder body 200, thereby enabling the motor 120 to drive the grinder 300 to rise relative to the grinder body 200 to adjust the grinding gap of the coffee beans.

[0029] like Figures 1 to 4As shown, further, the connecting end of the reset component 130 is used to be installed and fixed on the pulverizer body 200 and electrically connected to the drive motor 120. The sensing end of the reset component 130 is used to be disposed inside the pulverizer body 200. The sensing end of the reset component 130 is disposed opposite to the adjusting end of the transmission adjustment component 110. The sensing end of the reset component 130 is used to detect the position of the adjusting end of the transmission adjustment component 110, so that when the sensing end of the reset component 130 detects that the adjusting end of the transmission adjustment component 110 has reached a preset position, the connecting end of the reset component 130 can transmit the sensing signal to the transmission adjustment component 120. The motor 120 enables the transmission motor 120 to drive the adjustment end of the transmission adjustment component 110 to reset to the initial position relative to the grinder body 200. Compared with traditional coffee grinders that require a servo motor to control the lifting mechanism to rise or fall relative to the machine body, the transmission motor 120 of the adjustable coarseness coffee grinder 10 disclosed herein only needs to use a common motor to control the adjustment end of the transmission adjustment component 110 to rise or fall relative to the grinder body 200, so as to realize the adjustment of the coarseness of the coffee powder, thereby greatly reducing the production cost of the adjustable coarseness coffee grinder 10.

[0030] It should be noted that the method by which the reset component 130 controls the transmission motor 120 to drive the adjustment end of the transmission adjustment component 110 to move relative to the main body 200 of the pulverizer via the sensing signal is prior art. This application only protects the positional connection relationship between the reset component 130, the transmission adjustment component 110 and the transmission motor 120.

[0031] The aforementioned reset adjustment structure 100, with the fixed end of the drive motor 120 mounted on the pulverizer body 200 and the drive end of the drive motor 120 located within the pulverizer body 200 and connected to the adjustment end of the drive adjustment assembly 110, drives the adjustment end of the drive adjustment assembly 110 to rise or fall relative to its mounting end. This allows the drive motor 120 to drive the adjustment end of the drive adjustment assembly 110 to rise from its initial position relative to the pulverizer body 200, thereby enabling the drive motor 120 to lift the pulverizing component 300 relative to the pulverizer body 200. The connection end of the reset assembly 130 is mounted on the pulverizer body 200 and electrically connected to the drive motor 120. The sensing end of the reset assembly 130 is located within the pulverizer body 200, and the sensing end of the reset assembly 130 is connected to the drive adjustment assembly 110. The adjustment end of the reset component 130 is set relative to the adjustment end of the transmission adjustment component 110. The sensing end of the reset component 130 is used to detect the position of the adjustment end of the transmission adjustment component 110. When the sensing end of the reset component 130 detects that the adjustment end of the transmission adjustment component 110 has reached the preset position, the connection end of the reset component 130 can transmit the sensing signal to the transmission motor 120. This allows the transmission motor 120 to drive the adjustment end of the transmission adjustment component 110 to reset to the initial position relative to the grinder body 200. Compared with traditional coffee grinders that require a servo motor to control the lifting mechanism to rise or fall relative to the machine body, the transmission motor 120 of the adjustable coarseness coffee grinder 10 disclosed herein only needs to use a common motor to control the adjustment end of the transmission adjustment component 110 to rise or fall relative to the grinder body 200, thereby greatly reducing the production cost of the adjustable coarseness coffee grinder 10.

[0032] like Figures 1 to 2As shown, in one embodiment, the transmission adjustment assembly 110 includes a fixing member 111 and an adjusting member 112. The mounting end of the transmission adjustment assembly 110 is disposed on the fixing member 111, and the adjusting end of the transmission adjustment is disposed on the adjusting member 112. The fixing member 111 forms a limiting groove 1111. The transmission end of the adjusting member 112 is limited within the limiting groove 1111, and the driving end of the transmission motor 120 is disposed within the limiting groove 1111 and is connected to the transmission end of the adjusting member 112. The transmission end of the adjusting member 112 slides against the inner wall of the limiting groove 1111, and the adjusting end of the adjusting member 112... The adjusting end of the adjusting member 112 is used to rotate and limit the connection with the first end of the grinding member 300. The adjusting end of the adjusting member 112 is used to drive the grinding member 300 to rise or fall relative to the transmission end of the adjusting member 112, so that the transmission motor 120 can drive the transmission end of the adjusting member 112 to rotate relative to the grinding machine body 200, so that the transmission end of the adjusting member 112 can drive the adjusting end of the adjusting member 112 to rise or fall relative to the grinding machine body 200, thereby causing the adjusting end of the adjusting member 112 to drive the grinding member 300 to rise or fall relative to the grinding machine body 200, so as to achieve the adjustment of the coarseness of the coffee powder.

[0033] like Figures 1 to 3 As shown, in one embodiment, the adjusting member 112 includes a transmission part 1121 and an adjusting part 1122. The transmission end of the adjusting member 112 is disposed in the transmission part 1121, and the adjusting end of the adjusting member 112 is disposed in the adjusting part 1122. The transmission part 1121 is disposed in the limiting groove 1111 and is connected to the driving end of the transmission motor 120. The first end of the transmission part 1121 slides and abuts against the top wall of the limiting groove 1111, and the second end of the transmission part 1121 slides and abuts against the bottom wall of the limiting groove 1111, so as to limit the transmission part 1121 within the limiting groove 1111. The top wall of the limiting groove 1111 forms a limiting through hole 1111a. The first end of the 1 forms a limiting flange 1121a, which is disposed in the limiting through hole 1111a and slides against the hole wall of the limiting through hole 1111a, so that the transmission part 1121 can rotate relative to the fixed part 111; the transmission part 1121 forms a threaded hole 1121b, and the outer peripheral wall of the first end of the adjustment part 1122 forms a threaded abutment surface 1122a. The first end of the adjustment part 1122 is disposed in the threaded hole 1121b and threadedly connected to the transmission part 1121, so that when the transmission motor 120 drives the transmission part 1121 to rotate relative to the adjustment part 1122, the adjustment part 1122 can rise or fall relative to the pulverizer body 200.

[0034] like Figures 1 to 3As shown, in one embodiment, the adjusting member 112 further includes a guide limiting rod 1123. The first end of the guide limiting rod 1123 is used to be installed and fixed on the inner wall of the first end of the pulverizer body 200. The second end of the adjusting part 1122 is formed with a guide limiting through hole 1122b corresponding to the guide limiting rod 1123. The second end of the guide limiting rod 1123 passes through the guide limiting through hole 1122b and slides against the hole wall of the guide limiting through hole 1122b, so that the guide limiting rod 1123 can limit the adjusting part 1122 and prevent the transmission part 1121 from driving the adjusting part 1122 to rotate relative to the pulverizer body 200. This allows the adjusting part 1122 to rise or fall relative to the pulverizer body 200 along the guiding direction of the guide limiting rod 1123 when the transmission part 1121 rotates relative to the pulverizer.

[0035] like Figures 1 to 2 As shown, in one embodiment, the main body 200 of the pulverizer has a first connecting through hole 210. The drive end of the transmission motor 120 passes through the first connecting through hole 210 and is disposed in the limiting groove 1111, so that the transmission motor 120 can drive the transmission part 1121 to rotate relative to the main body 200 of the pulverizer, so as to drive the adjustment part 1122 to rise or fall relative to the main body 200 of the pulverizer along the guiding direction of the guide limiting rod 1123.

[0036] like Figures 1 to 2 As shown, in one embodiment, the reset assembly 130 includes a connector 131 and a sensor 132. The connecting end of the reset assembly 130 is located on the connector 131, and the sensing end of the reset assembly 130 is located on the sensor 132. The connector 131 is used to install and fix it on the pulverizer body 200. The first end of the sensor 132 is fixed to and electrically connected to the connector 131, and the second end of the sensor 132 is used to be disposed inside the pulverizer body 200 and opposite to the adjustment part 1122. The sensor 132 is used to detect the transmission adjustment part 1122. The position is such that when the sensor 132 detects that the adjustment part 1122 has reached the preset position, the sensor 132 will transmit the sensing signal to the connector 131. After receiving the sensing signal from the sensor 132, the connector 131 will transmit the sensing signal to the drive motor 120, so that the drive motor 120 can drive the drive part 1121 to rotate relative to the reset direction of the pulverizer body 200, thereby enabling the adjustment part 1122 to reset to the initial position, so as to drive the pulverizer 300 to reset to the initial position.

[0037] like Figures 2 to 3As shown, in one embodiment, the sensing element 132 includes a signal output section 1321 and a signal receiving section 1322. The first ends of both the signal output section 1321 and the signal receiving section 1322 are fixedly and electrically connected to the connector 131. The second ends of the signal output section 1321 and the signal receiving section 1322 are disposed within the pulverizer body 200, and are spaced apart to form a sensing area 1323. A baffle 1122c is formed on one side of the second end of the adjusting section 1122 facing the sensing element 132. The baffle 1122c is disposed opposite to the sensing area 1323, so that when the transmission section 1121 rotates relative to the adjusting section 1122... When the transmission unit 1121 drives the adjustment unit 1122 to move along the preset position, the baffle 1122c will extend into the sensing area 1323 and block the signal of the signal output unit 1321, so that the signal receiving unit 1322 cannot receive the signal of the signal output unit 1321. At this time, the signal receiving unit 1322 will transmit the sensing signal to the connector 131, and then the connector 131 will transmit the sensing signal to the transmission motor 120, so that the transmission unit can drive the transmission unit 1121 to rotate relative to the reset direction, so that the adjustment unit 1122 can move relative to the pulverizer body 200 to the initial position, so as to drive the pulverizer 300 to reset to the initial position.

[0038] This disclosure also provides a coffee bean grinder 10 with adjustable coarseness, including a grinder body 200, a grinder component 300, and a reset adjustment structure 100 as described in any of the above embodiments. The mounting end of the transmission adjustment component 110 is installed and fixed inside the grinder body 200, and the adjustment end of the transmission adjustment component 110 is rotatably limited by the grinder component 300 of the grinder body 200. The fixed end of the transmission motor 120 is installed and fixed on the grinder body 200, and the driving end of the transmission motor 120 is disposed inside the grinder body 200 and is connected to the adjustment end of the transmission adjustment component 110.

[0039] like Figures 1 to 2 As shown, in one embodiment, the mounting end of the transmission adjustment component 110 has a first clearance hole 113, and the adjustment end of the transmission adjustment component 110 has a second clearance hole 114. The first end of the grinder 300 passes through the first clearance hole 113 and is disposed in the second clearance hole 114. The adjustment end of the transmission adjustment component 110 is connected to the rotation limit of the grinder 300. The second end of the grinder 300 and the second end of the grinder body 200 form a grinding zone 400, so that when the grinder 300 rotates relative to the grinder body 200, the second end of the grinder 300 can grind the coffee beans in the grinding zone 400.

[0040] like Figures 1 to 2 As shown, in this embodiment, the outer peripheral wall of the drive end of the transmission motor 120 is fitted with a drive gear 121, and the outer peripheral wall of the transmission part 1121 is fitted with a driven gear 1121c. The drive gear 121 and the driven gear 1121c are meshed and connected for transmission, so that the transmission motor 120 can drive the transmission part 1121 to rotate relative to the grinder body 200 more stably, thereby improving the stability and adjustment accuracy of the adjustable coffee bean grinder 10.

[0041] like Figures 1 to 2 As shown, in this embodiment, the adjustable coarseness coffee bean grinder 10 further includes a grinder drive 500. The grinder drive 500 is disposed on the grinder body 200. The grinder body 200 has a second connecting through hole 220. The drive end of the grinder drive 500 passes through the second connecting through hole 220 and is provided in a second clearance hole 114. The drive end of the grinder drive 500 has a limiting hole 510. The first end of the grinder 300 is disposed in the limiting hole 510 and slides against the wall of the limiting hole 510, so that the drive end of the grinder drive 500 can drive the grinder 300 to rotate relative to the grinder body 200, and the first end of the grinder 300 can move up and down relative to the drive end of the grinder drive 500.

[0042] like Figures 1 to 2 As shown, in this embodiment, the first end of the grinder 300 is formed with an annular limiting flange 310, and the inner peripheral wall of the second clearance hole 114 is formed with an annular limiting groove 1141 opposite to the annular limiting flange 310. The annular limiting flange 310 is located in the annular limiting groove 1141, and the outer wall of the annular limiting flange 310 slides against the inner wall of the annular limiting groove 1141, so that the grinder 300 can be limited and installed on the adjusting part 1122 by the annular limiting flange 310, so that the adjusting part 1122 can drive the grinder 300 to move up and down relative to the transmission part 1121; at the same time, the grinder drive 500 can also drive the grinder 300 to rotate relative to the adjusting part 1122 to grind the coffee beans in the grinder body 200.

[0043] like Figures 1 to 2 As shown, in this embodiment, the adjustable coarseness coffee bean grinder 10 further includes an upper grinding section 230 and a lower grinding section 320. The upper grinding section 230 is installed and fixed on the inner peripheral wall of the grinder body 200, and the lower grinding section 320 is installed and fixed on the second end of the grinder 300. The upper grinding section 230 and the lower grinding section 320 are arranged opposite to each other to form a grinding zone 400, so that when the grinder 300 rotates relative to the grinder body 200, the grinder 300 can grind the coffee beans in the grinding zone 400.

[0044] Compared with the prior art, this disclosure has at least the following advantages:

[0045] The aforementioned adjustable coarseness coffee bean grinder 10, with its fixed end of the drive motor 120 mounted on the grinder body 200 and its drive end located within the grinder body 200 and connected to the adjustment end of the transmission adjustment assembly 110, drives the adjustment end of the transmission adjustment assembly 110 to rise or fall relative to its mounting end. This allows the drive motor 120 to drive the adjustment end of the transmission adjustment assembly 110 to rise from its initial position relative to the grinder body 200, thereby enabling the drive motor 120 to lift the grinding component 300 relative to the grinder body 200. The reset assembly 130's connecting end is mounted on the grinder body 200 and electrically connected to the drive motor 120. The sensing end of the reset assembly 130 is located within the grinder body 200 and is connected to the transmission adjustment assembly... The adjustment ends of component 110 are arranged opposite each other. The sensing end of the reset component 130 is used to detect the position of the adjustment end of the transmission adjustment component 110. When the sensing end of the reset component 130 detects that the adjustment end of the transmission adjustment component 110 has reached the preset position, the connection end of the reset component 130 can transmit the sensing signal to the transmission motor 120, so that the transmission motor 120 can drive the adjustment end of the transmission adjustment component 110 to reset to the initial position relative to the grinder body 200. Compared with traditional coffee grinders that require servo motors to control the lifting mechanism to rise or fall relative to the machine body, the transmission motor 120 of the adjustable coarseness coffee bean grinder 10 disclosed herein only needs to use a common motor to control the adjustment end of the transmission adjustment component 110 to rise or fall relative to the grinder body 200, thereby greatly reducing the production cost of the adjustable coarseness coffee bean grinder 10.

[0046] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
