[0032] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0033] Please see Figures 1 to 6This is an embodiment of the electric coffee powder dispenser 10, comprising a handle assembly 100, a drive assembly 200, a base assembly 300, and a powder dispensing assembly 400. The handle assembly 100 includes a handle body 110 and a limiting plate 120 connected to each other. The base assembly 300 has a communicating powder dispensing receiving groove 301 and a vertical channel 302. The handle body 110 is movably inserted through the vertical channel 302, so that the handle body 110 and the base assembly 300 are vertically slidably connected, thereby allowing the handle body 110 to move up and down along the vertical channel 302. The limiting plate 120 also movably abuts against the base assembly 300. 00, and the limiting plate 120 is also located in the powder receiving groove 301, so that when the handle body 110 moves upward to a certain position, the limiting plate 120 abuts against the base assembly 300; the base assembly 300 is also provided with a receiving groove 303, the opening of the receiving groove 303 facing the limiting plate 120; the handle body 110 is provided with a drive mounting cavity 110a, the drive assembly 200 includes a charging module 210, a power supply battery 220, a motor 230, a Hall switch circuit board 240 and a sensing magnetic block 250, the charging module 210 and the power supply battery 220 are both located in the drive mounting cavity 110a, and the sensing magnetic block 250 is located in Within the receiving slot 303, the charging module 210, the power supply battery 220, the Hall switch circuit board 240, and a portion of the motor 230 are located in the drive mounting cavity 110a. The limiting plate 120 has a clearance hole 121 communicating with the drive mounting cavity 110a. The rotating end of the motor 230 passes through the clearance hole 121, and the rotating end of the motor 230 is also located within the powder distribution receiving slot 301. The charging output terminal of the charging module 210 is electrically connected to the charging terminal of the power supply battery 220, and the power supply output terminal of the power supply battery 220 is electrically connected to the power supply terminal of the Hall switch circuit board 240. The sensing terminal of the Hall switch circuit board 240... The Hall switch circuit board 240 is electrically connected to the sensing magnetic block 250 to form a current loop when the Hall switch circuit board 240 is close to the sensing magnetic block 250. The drive output terminal of the Hall switch circuit board 240 is electrically connected to the input terminal of the motor 230 so that the Hall switch circuit board 240 drives the motor 230 to work. The powder loosening component 400 is fixedly installed on the rotating end of the motor 230 so that when the motor 230 is energized, its rotating end drives the powder loosening component 400 to rotate. The powder loosening component 400 is located in the powder distribution receiving groove 301. The powder loosening component 400 is used to distribute coffee powder in the coffee powder cup after extending out from the powder distribution receiving groove 301.

[0034] In this embodiment, the drive assembly 200 uses a Hall switch circuit board 240 and a sensing magnetic block 250 to achieve electric powder dispensing. The sensing magnetic block 250 is disposed within the base assembly 300. When the coffee powder cup is placed, pressing down on the handle body 110 causes the components in the drive mounting cavity 110a to move downwards. At this time, the Hall switch circuit board 240 approaches the magnetic sensing block to start the motor 230, thereby driving the powder dispensing assembly 400 to rotate and dispensing the coffee powder, thus improving the efficiency of coffee powder dispensing. When the handle body 110 is lifted, the Hall switch circuit board 240... As the motor moves away from the magnetic induction block, the motor 230 is turned off, and the entire structure enters a standby state. This makes the electric coffee powder dispenser 10 more convenient to use and easier to operate. In addition, since the induction magnetic block 250 is located inside the receiving groove 303, it is hidden inside the entire structure of the electric coffee powder dispenser 10, thus not affecting the overall appearance. Furthermore, when the electric coffee powder dispenser 10 is about to run out of power, the wire can be connected to the charging module 210 to charge the power supply battery 220, thus eliminating the need for frequent battery replacements and making the charging operation more convenient.

[0035] To distribute coffee powder, the portafilter 110 is lowered. The charging module 210, power battery 220, motor 230, and Hall effect switch circuit board 240 follow. The Hall sensor in the Hall effect switch circuit board 240 detects the presence of magnetic material. Since the sensing magnet 250 is positioned within the receiving slot 303 and remains stationary, the Hall sensor gradually moves closer to the sensing magnet 250 as it moves downwards until it detects magnetic material, creating a circuit that drives the motor 230. This, in turn, rotates the powder dispensing assembly 400, achieving rapid powder distribution. When the portafilter moves upwards, the components inside also move upwards. The Hall sensor gradually moves away from the sensing magnet 250 as it moves downwards until it no longer detects magnetic material. At this point, the Hall effect switch circuit board 240 disconnects the power, and the motor 230 stops working.

[0036] Furthermore, such as Figure 3 and Figure 5 As shown, the outer side of the handle body 110 is provided with an abutment platform 110b, so that when the handle body 110 moves down to a certain position, the abutment platform 110b abuts against the base assembly 300; when the handle body 110 moves up to a certain position, the limiting plate 120 abuts against the base assembly 300. That is, a sliding path is formed between the abutment platform 110b and the limiting plate 120, so that the handle body can move up and down along the sliding path.

[0037] Furthermore, the sensing magnetic block 250 and the Hall switch circuit board 240 can be located in the same radial direction when they move relative to each other.

[0038] Furthermore, the handle body 110 and the base assembly 300 are interference-fitted to allow the handle body 110 to move up or down any distance and then hover.

[0039] like Figure 1 and Figure 2 As shown, in one embodiment, a vertical guide groove 111 is provided on the outer side of the handle body 110, and a vertical guide block 310 protrudes from the base assembly 300. The vertical guide block 310 is disposed on the inner wall of the vertical channel 302 and is located within the vertical guide groove 111, so that the handle body 110 is restricted by the vertical guide block 310 and the vertical guide groove 111 when moving up and down. That is, the vertical guide block 310 performs a single-axis movement within the vertical guide groove 111, i.e., the handle body 110 moves vertically upward or vertically downward, and the handle body 110 itself does not rotate in the horizontal direction. In this embodiment, there are two vertical guide grooves 111, and the two vertical guide grooves 111 are disposed opposite each other on the outer side of the handle body 110. There are also two vertical guide blocks 310, and the two vertical guide blocks 310 are disposed opposite each other on the inner wall of the vertical channel 302.

[0040] like Figure 1 , Figure 3 or Figure 5 As shown, in one embodiment, the handle assembly 100 further includes a protective cover 500, which is disposed on the handle body 110 to cover the interface of the charging module 210, preventing the interface of the charging module 210 from being exposed to moisture or dust for a long time, thus affecting battery charging. Further, the protective cover 500 is a silicone cover.

[0041] like Figure 3 or Figure 6 As shown, in one embodiment, the electric coffee powder dispenser 10 further includes a washer 600, and the base assembly 300 has a mounting ring groove 304, the opening of which faces away from the limiting plate 120. The washer 600 is disposed in the mounting ring groove 304. Thus, when the electric coffee powder dispenser 10 is placed, the washer 600 rests against a horizontal surface, preventing structural wear caused by direct contact between the base assembly 300 and the horizontal surface.

[0042] like Figure 3 or Figure 6As shown, in one embodiment, the electric coffee powder dispenser 10 also includes multiple magnetic blocks 700, and the base assembly 300 has multiple magnetic pre-loading slots 305. The openings of the multiple magnetic pre-loading slots 305 are away from the limiting plate 120, and each magnetic block 700 is located in a corresponding magnetic pre-loading slot 305. It can be understood that when using magnetic blocks 700, the coffee powder cup is usually made of stainless steel, such as 304 stainless steel or 316 stainless steel. After the coffee powder cup is placed, the electric coffee powder dispenser 10 uses its magnetic blocks 700 to hold the coffee powder cup in place, preventing the coffee powder cup from shaking or falling off during the powder dispensing operation, thus ensuring the stability of the coffee powder dispensing step.

[0043] like Figure 3 and Figure 7 As shown, in one embodiment, the coffee powder dispensing assembly 400 includes a needle holder 410, a stirring needle assembly 420, and a mounting component 430. The stirring needle assembly 420 is disposed on the side of the needle holder 410 facing away from the limiting plate 120. The needle holder 410 is fixedly connected to the mounting component 430, which is fixedly sleeved on the rotating end of the motor 230. Thus, the needle holder 410 is fixedly connected to the rotating end of the motor 230 through the mounting component 430. When the motor 230 is working, it will drive the needle holder 410 to rotate through the mounting component 430, thereby driving the stirring needle assembly 420 to rotate, in order to distribute the coffee powder. In this embodiment, the stirring needle assembly 420 includes multiple stirring needles, which are staggered on the side of the needle holder 410 facing away from the limiting plate 120 to ensure that the coffee powder can be stirred in more locations.

[0044] like Figure 3 , Figure 5 and Figure 7As shown, in one embodiment, the mounting component 430 includes a locating pin 431, a bearing 432, a locating sleeve 433, and a screw connector 434. The locating sleeve 433 has a first through hole 433a, the locating pin 431 has a second through hole 431a, the screw connector 434 passes through the first through hole 433a and the second through hole 431a, and the end of the screw connector 434 abuts against the rotating end of the motor 230. The pin bracket 410 is arranged around the bearing 432, and the bearing 432 is arranged around the locating pin 431. The top of pin 431 abuts against bearing 432 and pin bracket 410 respectively. Pin bracket 410 also abuts against positioning sleeve 433, so that positioning pin 431 and positioning sleeve 433, as well as positioning pin 431 and rotating end of motor 230 are fixedly connected by screw connector 434, and the connection is relatively firm. Furthermore, the top of positioning pin 431 abuts against bearing 432 and pin bracket 410 respectively to prevent pin bracket 410 from falling off. In this way, when motor 230 is working, pin bracket 410 is not likely to loosen or even fall off. In this embodiment, screw connector 434 is a headless screw, so that the whole is located in the first through hole 433a and the second through hole 431a, and no part of the structure protrudes.

[0045] like Figure 6 As shown, in one embodiment, the base assembly 300 has a bracket window 306, and the powder distribution groove 301 communicates with the bracket window 306. It is understood that when the needle bracket 410 or bearing 432 needs to be replaced, an auxiliary tool, such as a screwdriver, is needed to loosen the screw connector 434 to disassemble the entire powder distribution assembly 400. This tool can pass through the bracket window 306 into the powder distribution groove 301 to act on the screw connector 434, thus improving the convenience of component replacement. Similarly, when the component 430 needs to be fixed by the screw connector 434 after installation, the auxiliary tool magnetically attracts the screw connector 434, passes it through the bracket window 306, and then enters the powder distribution groove 301. The screw connector 434 is then tightened until it abuts against the rotating end of the motor 230.

[0046] This disclosure also provides a coffee powder distribution device, including the electric coffee powder distributor 10 of any of the above embodiments.

[0047] Compared with the prior art, this disclosure has at least the following advantages:

[0048] 1. Since the drive component 200 of the electric coffee powder dispenser 10 uses a Hall switch circuit board 240 and a magnetic induction block 250 to achieve electric powder dispensing, and the magnetic induction block 250 is set in the base component 300, when the coffee powder cup is placed, pressing down the handle body 110 causes the components in the drive mounting cavity 110a to move downwards. At this time, the Hall switch circuit board 240 approaches the magnetic induction block to start the motor 230, which in turn drives the powder dispensing component 400 to rotate and perform the powder dispensing action, thereby improving the efficiency of coffee powder dispensing. When the handle body 110 is lifted, the Hall switch circuit board 240 gradually moves away from the magnetic induction block to turn off the motor 230, and the entire structure is in standby mode. Thus, the electric coffee powder dispenser 10 is highly convenient to use and easy to operate.

[0049] 2. Since the induction magnet 250 is located inside the receiving groove 303, it is hidden inside the entire structure of the electric coffee powder dispenser 10, so as not to affect the overall appearance.

[0050] 3. When the electric coffee powder dispenser 10 is about to run out of power, the wire can be connected to the charging module 210 to charge the power supply battery 220, thus eliminating the need for frequent battery replacements and making the charging operation more convenient.

[0051] 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.
