Description
Technical Field
[0001] This utility model relates to the technical field of coffee machines, and in particular to a coffee machine powder dispensing mechanism. Background Technology
[0002] Currently, most coffee-making equipment has a relatively simple coffee powder outlet structure, often employing a direct opening or a simple flip-top design. With direct opening outlets, coffee powder can easily leak out uncontrollably during equipment movement, shaking, or coffee powder loading, resulting in waste and potential environmental contamination, affecting the equipment's normal operation and appearance. While simple flip-top designs reduce leakage to some extent, their sealing performance is limited, making it difficult to completely prevent coffee powder leakage. Especially during equipment vibration, gaps may appear in the flip-top, allowing coffee powder to leak out.
[0003] In view of this, the designer of this utility model, in order to solve the above problems, has deeply conceived and actively researched, improved and tested, and developed this utility model. Utility Model Content
[0004] The purpose of this invention is to provide a coffee machine powder dispensing mechanism that can solve the above-mentioned powder leakage problem, and has the advantages of preventing powder leakage and ensuring a reliable seal at the powder dispensing port.
[0005] To achieve the above objectives, the solution of this utility model is: A coffee machine's powder dispensing mechanism includes a powder dispensing nozzle, a baffle, a bracket, a pusher, and a drive component; The baffle is rotatably and openably installed at the front end of the powder outlet of the powder nozzle; The baffle has a sealing part on one side that is located at the powder outlet, and a magnetic part on the other side that is located outside the powder outlet. When the magnetic part swings, the baffle rotates, which in turn drives the sealing part to swing, thereby opening and closing the powder outlet. The bracket is located on the front side of the powder outlet, and a bracket magnetic suction component is provided on the bracket near the magnetic suction part; when the magnetic suction part of the baffle is magnetically fixed to the bracket magnetic suction component, the sealing part of the baffle completely covers and seals the powder outlet. The pusher block is reciprocally mounted on one side of the baffle and can engage or disengage between the magnetic suction part of the pusher block and the magnetic suction part of the bracket as driven by the drive component. When the pusher block engages between the magnetic suction part and the magnetic suction part of the bracket, the magnetic suction part moves away from the magnetic suction part of the bracket, causing the sealing part to open the powder outlet. When the pusher block disengages between the magnetic suction part and the magnetic suction part of the bracket, the magnetic suction part is attracted and fixed to the magnetic suction part of the bracket, causing the sealing part to seal and close the powder outlet.
[0006] Furthermore, the powder nozzle has a downward-sloping groove inside, with the opening at the front of the groove serving as the powder outlet; an anti-static iron plate is installed on the bottom surface of the groove, and the anti-static iron plate is connected to the ground wire of the coffee machine.
[0007] Furthermore, the magnetic part of the baffle is located above the powder outlet; the top surface of the powder outlet is provided with a powder outlet magnetic component; when the push block pushes the magnetic part of the baffle to separate it from the magnetic component of the bracket, the magnetic part can be magnetically fixed with the powder outlet magnetic component. The support is cylindrical, with a notch on the side wall for the powder nozzle to extend into; when the baffle rotates, the lower sealing part can swing forward and is located in the lower inner part of the support, while the upper magnetic part of the baffle is always located in the outer part of the support; a water pressure chamber is provided in the upper inner part of the support, and when the powder is discharged from the outlet, the brewing head of the water pressure chamber can press down and reset the sealing part located in the lower inner part of the support.
[0008] Furthermore, the upper middle part of the baffle may be provided with rotating shafts at both ends, and two hinge ears are provided above the powder outlet of the powder nozzle, with rotating holes for the rotating shafts to be inserted into the hinge ears.
[0009] Furthermore, the magnetic suction part is a plate-shaped structure with a fixing hole through both ends in the middle, and a magnet is installed in the fixing hole; the magnetic suction part of the bracket and the magnetic suction part of the powder outlet are respectively installed and fixed in the groove provided on the bracket or the powder outlet, and both are made of magnetic material.
[0010] Furthermore, the powder outlet end face is an arc-shaped end face with a concave center, and the sealing part is an arc-shaped plate that matches the powder outlet end face.
[0011] Furthermore, the front side of the push block reciprocates against the outer wall of the bracket; the rear side of the push block has a rearward protrusion, and the rear side of the push block near the magnetic attraction part has a first inclined surface; the front side of the end of the baffle magnetic attraction part near the push block has a second inclined surface that cooperates with the first inclined surface.
[0012] Furthermore, the driving component is a solenoid valve with a telescopic rod; the push block is connected to the telescopic rod of the solenoid valve via a connecting rod.
[0013] Furthermore, both the powder nozzle and the bracket are mounted on the mounting plate; the powder nozzle has a connecting part on its rear side, and the powder nozzle is locked to the edge of the mounting opening in the middle of the mounting plate through the connecting part; the bracket is integrally formed on one side of the mounting opening of the mounting plate; the bracket is cylindrical, and the side wall of the bracket has a bracket notch for the powder nozzle to extend into.
[0014] With the above technical solution, when the powder outlet nozzle does not need to dispense powder, the powder outlet can be sealed by the baffle sealing part. Moreover, when the sealing part seals the powder outlet, the magnetic suction part is magnetically fixed to the magnetic suction component of the bracket, effectively ensuring that the baffle will not rotate arbitrarily and cause powder leakage from the powder outlet. When the powder outlet nozzle needs to dispense powder, the push block can be automatically driven by the drive component to move, causing the magnetic suction part of the baffle to separate from the magnetic suction component of the bracket, thereby causing the baffle to rotate around the central axis, so that the baffle sealing part opens the powder outlet. After the drive component drives the push block away from the magnetic suction part, the magnetic suction part can be magnetically fixed to the magnetic suction component of the bracket again, so that the sealing part reliably seals the powder outlet.

Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0018] like Figures 1 to 6 As shown, a coffee machine powder dispensing mechanism according to this embodiment includes a powder dispensing nozzle 1, a baffle 2, a bracket 3, a pusher block 4, and a drive component 5.
[0019] like Figure 3 As shown, a rotatable baffle 2 is installed at the front end of the powder outlet 11 of the powder nozzle 1. The upper part of the baffle 2 can be rotatably connected to the upper side of the outer periphery of the powder outlet 11. The lower side of the baffle 2 has a sealing part 21 located at the powder outlet 11. The upper side of the baffle 2 has a magnetic suction part 22 located outside the powder outlet 11. When the magnetic suction part 22 swings, the baffle 2 rotates, thereby driving the sealing part 21 to swing, so as to open and close the powder outlet 11.
[0020] like Figure 2 As shown, the bracket 3 is located in front of the powder outlet 11. The bracket 3 can be cylindrical. The side wall of the bracket 3 can have a bracket notch 31 for the powder nozzle 1 to extend into. The bracket 3 is provided with a bracket magnetic suction member 32 near the magnetic suction part 22. When the magnetic suction part 22 of the baffle 2 is magnetically fixedly connected to the bracket magnetic suction member 32, the sealing part 21 of the baffle 2 can completely cover and seal the powder outlet 11.
[0021] The pusher 4 is movably mounted above the baffle 2 and can be engaged or disengaged between the magnetic suction part 22 and the support magnetic suction part 32 as driven by the drive component 5. When the pusher 4 engages between the magnetic suction part 22 and the support magnetic suction part 32, the magnetic suction part 22 can swing and disengage from the support magnetic suction part 32, thereby driving the baffle 2 to rotate and open the powder outlet 11 of the sealing part 21 (e.g., Figure 5 When the pusher 4 exits between the magnetic suction part 22 and the bracket magnetic suction member 32, the baffle 2 can reset so that the magnetic suction part 22 is re-attached and fixed to the bracket magnetic suction member 32 (e.g. Figure 6 ), causing the sealing part 21 to reseal and close the powder outlet 11.
[0022] Therefore, when the powder nozzle 1 does not need to dispense powder, the powder outlet 11 can be sealed by the sealing part 21 of the baffle 2. When the sealing part 21 seals the powder outlet 11, the magnetic part 22 is magnetically attracted and fixed to the magnetic part 32 of the bracket, effectively ensuring that the baffle 2 will not rotate arbitrarily and cause powder leakage from the powder outlet 11. When the powder nozzle 1 needs to dispense powder, there is no need to manually control the rotation of the baffle 2. The push block 4 can be automatically driven by the drive member 5 to move downward, and the magnetic part 22 of the baffle 2 will separate from the magnetic part 32 of the bracket. Then, the baffle 2 will rotate around the middle axis, and the sealing part 21 of the baffle 2 will open the powder outlet 11. When the drive member 5 drives the push block 4 to move upward away from the magnetic part 22, the magnetic part 22 can be magnetically attracted and fixed to the magnetic part 32 of the bracket again, so that the sealing part 21 reliably seals the powder outlet 11.
[0023] In this embodiment, both the powder outlet 1 and the bracket 3 can be mounted on the mounting plate 6 to facilitate assembly with the coffee machine. The powder outlet 1 has an arc-shaped connecting part 7 on its rear side, and the powder outlet 1 has a downward-sloping groove 12 inside, with the front opening of the groove 12 being the powder outlet 11. The powder outlet 1 can be locked to the edge of the mounting opening 61 in the middle of the mounting plate 6 via the connecting part 7. The bracket 3 can be integrally formed on one side of the mounting opening 61 of the mounting plate 6, but is not limited to this.
[0024] The front end of the powder outlet 1 can extend into the bracket notch 31 (e.g. Figure 5 When the baffle 2 rotates, the lower sealing part 21 can swing forward and be located at the lower inner side of the bracket 3, while the upper magnetic suction part 22 of the baffle 2 is always located at the outer side of the bracket 3. A water pressure chamber 8 can be provided at the upper inner side of the bracket 3. After the powder outlet 11 finishes discharging powder, the cooking head 81 of the water pressure chamber 8 presses down, which can push and reset the sealing part 21 located at the lower inner side of the bracket 3 (e.g., Figure 6 This forces the baffle 2 to rotate and reset.
[0025] The structure of the pressure chamber 8 can refer to the existing technology, mainly using water pressure to press down the brewing head 81 to perform the tamping action of coffee powder.
[0026] The top surface of the powder outlet 1 can be an inclined surface parallel to the top surface of the slide groove 12, or it can be set as a plane. The top surface of the powder outlet 1 can be provided with a powder outlet magnetic suction member 13. Thus, when the push block 4 pushes the magnetic suction part 22 of the baffle 2 to separate it from the support magnetic suction member 32, the magnetic suction part 22 can be flipped and close to the top surface of the powder outlet 1, and can then be magnetically fixed by the powder outlet magnetic suction member 13, so that the sealing part 21 remains separated from the powder outlet 11, keeping the powder outlet 11 always in the open state, ensuring smooth powder dispensing. Thus, after the drive member 5 drives the push block 4 to push open the magnetic suction part 22 and the support magnetic suction member 32, the push block 4 can be driven to reset again, so as to save energy and reduce power consumption.
[0027] In this embodiment, when the magnetic suction part 22 is attracted and fixed to the support magnetic suction part 32 or the powder outlet magnetic suction part 13, they can be tightly attached to each other or there can be a certain gap. When they are tightly attached to each other, the fixing effect is better, and when there is a gap, it is convenient for the push block 4 to intervene. It can be set according to actual needs.
[0028] like Figure 3 As shown in this embodiment, the upper middle part of the baffle 2 may be provided with rotating shafts 23 at both ends, and two hinge ears 14 may be provided above the powder outlet 11 of the powder outlet 1. The hinge ears 14 are provided with rotating holes 141 for the rotating shafts 23 to be inserted.
[0029] In this embodiment, the magnetic suction part 22 can be a plate-shaped structure with a fixing hole 221 through both ends in the middle. A magnet 222 can be installed in the fixing hole 221. The bracket magnetic suction part 32 and the powder dispensing nozzle magnetic suction part 13 can be respectively installed and fixed in the groove provided on the bracket 3 or the powder dispensing nozzle 1. Both can be made of magnetic materials such as magnet 222 or iron sheet, so that the magnetic suction part 22 can be magnetically attracted and fixed with the bracket magnetic suction part 32 or the powder dispensing nozzle magnetic suction part 13. Alternatively, a magnetic material such as iron sheet other than magnet 222 can be installed in the fixing hole 221, and the bracket magnetic suction part 32 and the powder dispensing nozzle magnetic suction part 13 can be set as magnet 222.
[0030] In this embodiment, the end face of the powder outlet 11 can be an arc-shaped end face with a concave center, and the sealing part 21 can be an arc-shaped plate that matches the end face of the powder outlet 11 to ensure the sealing and fixing effect of the powder outlet 11.
[0031] Normally, coffee powder easily generates static electricity during grinding and transport. This static electricity can cause coffee powder to adhere to the area around the powder outlet 11, or cause powder to fly out during dispensing, affecting the smoothness of powder dispensing. Long-term accumulation can also lead to blockage of the powder outlet 11, affecting the efficiency and quality of coffee making. Therefore, in this embodiment, an anti-static iron plate 15 is installed on the bottom surface of the slide 12 inside the powder outlet 11. This anti-static iron plate 15 can be connected to the ground wire of the coffee machine. Thus, when powder is dispensed from the powder outlet 11, the static electricity of the coffee powder passing through the anti-static iron plate 15 can be eliminated, preventing coffee powder from flying out.
[0032] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the front side of the push block 4 can move up and down against the outer wall of the bracket 3. The outer wall of the bracket 3 can be provided with a guide plane for the push block 4 to slide and fit. The rear side of the push block 4 can have a rearward protrusion 41. The rear side of the push block 4 near the bottom of the magnetic suction part 22 has a first inclined surface 42. The front side of the magnetic suction part 22 of the baffle 2 near the top of the push block 4 has a second inclined surface 223 that cooperates with the first inclined surface 42. Thus, when the push block 4 moves down, it can use the first inclined surface 42 to align and insert into the gap formed between the second inclined surface 223 and the side wall of the bracket 3, so that the push block 4 can smoothly intervene between the magnetic suction part 22 and the bracket magnetic suction part 32, and use the protrusion 41 to push the magnetic suction part 22 backward.
[0033] In this embodiment, the driving component 5 is described using a solenoid valve with a telescopic rod 51 as an example. The driving component 5 can be installed in a card holder 62 provided on one side of the bracket 3. The top of the push block 4 can be provided with an inverted "L"-shaped connecting rod 43, which is connected to the telescopic rod 51 of the solenoid valve. The solenoid valve can stably drive the telescopic rod 51 and the push block 4 to move up and down. Of course, the driving component 5 can also use a motor screw, electric cylinder, pneumatic cylinder, or other structures to move the push block 4, and is not limited to this embodiment.

All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, equivalent changes and modifications without departing from the principle of this utility model should still fall within the protection scope of this utility model.
