Description

Technical Field

[0001] This utility model relates to the field of milk maker technology, and more specifically, to an assembly structure for a powder outlet sealing plate for a milk maker. Background Technology

[0002] A formula maker is a household appliance that automatically dispenses formula, controls water temperature, and prepares the formula. It is widely used for preparing infant formula. One of the key components of a formula maker is the powder inlet sealing plate assembly structure, which ensures the airtightness of the powder delivery chamber when the powder inlet is closed.

[0003] Currently, the common assembly structure of the powder outlet sealing plate in milk makers on the market includes a powder outlet and a powder outlet sealing plate. The powder outlet is opened and closed by the horizontal rotation of the powder outlet sealing plate. Since the powder outlet sealing plate is frequently opened and closed as needed, the milk powder in the powder delivery chamber will become damp after a period of use, and then accumulate on the powder outlet sealing plate. This not only easily breeds bacteria, but also affects the sealing performance of the powder outlet. The existing powder outlet sealing plate and the drive mechanism are often integrated together, which requires the entire mechanism to be disassembled for cleaning, increasing the difficulty of cleaning and making it easy for water to enter and damage electrical components. Utility Model Content

[0004] The technical problem this invention aims to solve is that the sealing plate of the powder outlet of existing milk maker is inconvenient to disassemble and clean, affecting the sealing effect of the powder outlet sealing plate. To overcome the above-mentioned defects of the prior art, this invention provides a method that facilitates the disassembly and assembly of the powder outlet sealing plate by means of a detachable limiting cover, thereby enabling the powder outlet sealing plate to be rinsed, ensuring the hygiene of the powder outlet sealing plate, and also ensuring the sealing effect of the powder outlet.

[0005] To achieve the purpose of this utility model, the following technical solution is adopted:

[0006] An assembly structure for a powder outlet sealing plate in a milk powder maker includes a milk powder box, a powder outlet sealing plate, and a limiting cover. The bottom surface of the milk powder box has an installation groove. A stirring chamber and a powder delivery chamber are respectively arranged within the installation groove. One side of the powder delivery chamber communicates with the stirring chamber, and a powder outlet is provided at the bottom of the powder delivery chamber. A stirring drive assembly is provided within the stirring chamber. The powder outlet sealing plate is horizontally rotatably connected to the stirring drive assembly. The powder outlet sealing plate has a transmission part that drives the machine body, and the powder outlet is opened and closed by rotating the powder outlet sealing plate. The limiting cover is detachably installed on the outer stirring chamber, and after the limiting cover is fixed, it limits the powder outlet sealing plate between the stirring chamber and the limiting cover. This structure uses a detachable limiting cover to easily limit and fix the powder outlet sealing plate. It also makes it easy to remove the powder outlet sealing plate for cleaning after the milk maker has been used for a period of time. This allows for the rinsing of residual milk powder and bacteria caused by moisture on the powder outlet sealing plate, and also solves the problem of poor sealing effect caused by milk powder accumulation. Ultimately, this ensures the hygiene of the powder outlet sealing plate and the sealing effect of the powder outlet.

[0007] Preferably, a sealing plug is detachably installed on the powder outlet sealing plate corresponding to the powder outlet. When the powder outlet is closed, the sealing plug is in a sealing fit with the powder outlet. The detachable sealing plug allows for easy replacement or cleaning, ensuring that the powder outlet is always sealed in the closed state, preventing powder leakage and the growth of bacteria due to moisture.

[0008] Preferably, the powder outlet sealing plate is provided with a sealing groove corresponding to the powder outlet; the sealing plug is engaged in the sealing groove, and the outer peripheral wall of the sealing plug is tightly fitted onto the inner peripheral wall of the sealing groove. The engagement between the sealing groove and the sealing plug facilitates disassembly and assembly, improves the convenience of replacement and cleaning, and also ensures a good sealing effect.

[0009] Preferably, the contact surface of the sealing plug that mates with the powder outlet is an arc shape with the opening facing downwards; when the powder outlet is closed, the contact surface is press-fitted into the powder outlet and seals it. The arc-shaped contact surface further ensures a good seal with the powder outlet, thereby preventing the milk powder in the powder delivery chamber from getting damp and developing bacteria, and preventing powder leakage from the powder outlet.

[0010] Preferably, the bottom end of the side wall of the mounting groove, corresponding to the lower powder outlet sealing plate, is provided with a radially inwardly protruding arc-shaped support plate. The rotation angle of the arc-shaped support plate matches the rotation angle of the lower powder outlet sealing plate. The bottom surface of the outer end of the lower powder outlet sealing plate abuts against the top surface of the arc-shaped support plate, allowing the outer end of the lower powder outlet sealing plate to rotate along the arc-shaped support plate. The arc-shaped support plate supports the outer end of the lower powder outlet sealing plate, ensuring that the lower powder outlet sealing plate can rotate horizontally, while also ensuring the stability and connectivity of the rotation of the lower powder outlet sealing plate, thereby ensuring that the lower powder outlet sealing plate always maintains a good sealing effect on the lower powder outlet.

[0011] Preferably, the stirring chamber includes an outer annular support plate and an inner annular support plate that protrude downwards from the bottom of the mounting groove, and the outer and inner annular support plates are coaxially arranged. The stirring drive assembly is installed inside the inner annular support plate, and the outer annular support plate has a plurality of L-shaped tightening slots arranged circumferentially on its outer peripheral wall. The limiting cover plate has an L-shaped tightening block arranged circumferentially on its inner peripheral wall that locks into the L-shaped tightening slots. Through the rotational engagement of the L-shaped tightening block and the L-shaped tightening slot, it is ensured that the limiting cover plate is fixed to the outer annular support plate when tightened, and it can also be easily unscrewed to disengage the limiting cover plate from the outer annular support plate, improving the convenience of opening and locking the limiting cover plate and ensuring the stability of the locking.

[0012] Preferably, the bottom surface of the outer annular support plate is lower than the bottom surface of the inner annular support plate, and a height difference is formed between the outer and inner annular support plates for installing the powder outlet sealing plate. The outer annular support plate has an arc-shaped limiting opening along its circumference on one side of the powder outlet to restrict the rotation of the powder outlet sealing plate. A stirring drive assembly is installed inside the inner annular support plate, and the powder outlet sealing plate is rotatably sleeved on the stirring drive assembly, with the bottom surface of the powder outlet sealing plate not exceeding the bottom surface of the outer annular support plate. The arc-shaped limiting opening facilitates the rotational limiting of the powder outlet sealing plate, allowing it to be positioned at the open limiting point at one end of the arc-shaped limiting opening and the closed limiting point at the other end, thus enabling more precise rotation of the powder outlet sealing plate to the designated state.

[0013] Preferably, the powder outlet sealing plate is disc-shaped, and a circular through hole is provided in the center of the powder outlet sealing plate to rotatably engage with the stirring drive assembly. The transmission part is a drive positioning socket provided on the powder outlet sealing plate; the drive positioning socket is used to cooperate with the drive positioning plug on the machine body to realize the rotation of the powder outlet sealing plate; an extension is provided radially on one side of the outer wall of the powder outlet sealing plate; the extension extends through the arc-shaped limiting opening to the powder outlet. The drive positioning socket facilitates the insertion and cooperation with the drive positioning plug, thereby driving the drive positioning plug to rotate via the motor, which in turn drives the powder outlet sealing plate to rotate, allowing the extension to cover or expose the powder outlet, ultimately closing or opening the powder outlet.

[0014] Preferably, the stirring drive assembly includes a rotating block, a bottom seal, and a stirring shaft arranged coaxially; the rotating block is rotatably connected to the inner annular support plate through the bottom seal, the stirring shaft is fixedly connected to the rotating block, and the stirring shaft extends through the mounting groove into the inside of the milk powder box; the powder outlet sealing plate is rotatably sleeved on the rotating block.

[0015] Preferably, the top of the milk powder box is provided with a powder storage cavity; the bottom of the powder storage cavity is provided with a powder inlet that communicates with the inner cavity of the powder delivery cavity; the stirring shaft extends through the mounting groove into the powder storage cavity, and the top of the stirring shaft is connected to a stirring head; the top of the powder storage cavity is not closed, and a box cover is installed on the top of the milk powder box to seal the top of the powder storage cavity; a number of reinforcing ribs are evenly distributed circumferentially between the outer annular support plate and the inner annular support plate.

[0016] In summary, the advantages of this utility model are that the detachable limiting cover plate facilitates the limiting and fixing of the powder outlet sealing plate, and also makes it easy to remove the powder outlet sealing plate for cleaning after the milk maker has been used for a period of time. This allows for the rinsing away of milk powder residue and bacteria caused by moisture on the powder outlet sealing plate, and also solves the problem of poor sealing effect caused by milk powder accumulation in the powder outlet sealing plate. Ultimately, this ensures the hygiene of the powder outlet sealing plate and also ensures a better sealing effect on the powder outlet. Attached Figure Description

[0026] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 4As shown, a powder outlet sealing plate assembly structure for a milk powder maker includes a milk powder box 1, a powder outlet sealing plate 2, and a limiting cover plate 3; the milk powder box 1 is cylindrical, and the top of the milk powder box 1 is provided with an upward-opening powder storage cavity 10; the top of the powder storage cavity 10 is not closed, and a box cover 7 is installed on the top of the milk powder box 1, and the top of the powder storage cavity 10 is sealed by the box cover 7. The bottom surface of the milk powder box 1 is provided with a downward-facing, circular mounting groove 11. A stirring chamber and a powder delivery chamber 4 are respectively provided in the mounting groove 11. The stirring chamber includes an outer annular support plate 12 and an inner annular support plate 13, which are located at the center of the bottom of the mounting groove 11 and protrude downwards. The outer annular support plate 12 and the inner annular support plate 13 are coaxially arranged. Both the outer annular support plate 12 and the inner annular support plate 13 are hollow cylinders. The outer annular support plate 12 and the inner annular support plate 13 are integrally formed on the milk powder box 1. Four reinforcing ribs 14 are evenly distributed circumferentially between the outer annular support plate 12 and the inner annular support plate 13. The four reinforcing ribs 14 are arranged in a cross shape and integrally formed on the milk powder box 1. The reinforcing ribs 14 ensure the stability and connectivity of the overall structure. The powder feeding chamber 4 is radially distributed within the mounting groove 11, and is located below the powder storage chamber 10. The powder feeding chamber 4 extends radially inward through the outer annular support plate 12 and into the inner annular support plate 13. The bottom of the powder storage chamber 10 is provided with a powder inlet 101 communicating with the inner cavity 40 of the powder feeding chamber 4. The bottom of the radially outer side of the powder feeding chamber 4 is provided with a powder outlet 41 communicating with the inner cavity 40. The powder outlet sealing plate 2 is horizontally rotatably connected to the outer annular support plate 12. The powder outlet sealing plate 2 is disc-shaped, and its... An extension 203 is provided radially on one side of the outer wall; the extension 203 extends to the powder outlet 41, and the top surface of the extension 203 is horizontal and seals with the bottom surface of the powder outlet 41. The powder outlet sealing plate 2 is provided with a transmission part that drives the machine body, and the powder outlet 41 is opened and closed by rotating the powder outlet sealing plate 2. The limiting cover plate 3 is detachably installed on the outer annular support plate 12, and after the limiting cover plate 3 is fixed, the powder outlet sealing plate 2 is limited between the inner annular support plate 13 and the limiting cover plate 3. This structure uses a detachable limiting cover 3 to easily limit and fix the powder outlet sealing plate 2. It also makes it easy to remove the powder outlet sealing plate 2 for cleaning after the milk maker has been used for a period of time. This allows for the rinsing of milk powder residue and bacteria caused by moisture on the powder outlet sealing plate 2. It also solves the problem of poor sealing effect caused by milk powder accumulation on the powder outlet sealing plate 2, ultimately ensuring the hygiene of the powder outlet sealing plate 2 and the sealing effect of the powder outlet 41.

[0028] like Figures 1 to 4As shown, a sealing plug 5 is detachably installed on the powder outlet sealing plate 2 corresponding to the powder outlet 41. When the powder outlet 41 is closed, the sealing plug 5 seals against the powder outlet 41. The detachable sealing plug 5 facilitates replacement or cleaning, ensuring the powder outlet 41 remains sealed and preventing powder leakage and bacterial growth due to moisture. A sealing groove 21 is provided on the powder outlet sealing plate 2 corresponding to the powder outlet 41; the sealing plug 5 is engaged within the sealing groove 21, with its outer peripheral wall tightly fitted against the inner peripheral wall of the sealing groove 21. The engagement between the sealing groove 21 and the sealing plug 5 facilitates disassembly and assembly, improving the ease of replacement and cleaning while ensuring a good sealing effect. The contact surface 50 on the sealing plug 5 that mates with the powder outlet 41 is an arc shape with an opening facing downwards; when the powder outlet 41 is closed, the contact surface 50 is press-fitted against the powder outlet 41, sealing it. The arc-shaped contact surface 50 further ensures a tight seal with the powder outlet 41, thereby preventing the milk powder in the powder delivery cavity 4 from getting damp and generating bacteria, and preventing powder leakage from the powder outlet 41.

[0029] like Figure 3 and Figure 4 As shown, three L-shaped tightening slots 121 are evenly distributed circumferentially on the outer peripheral wall of the outer annular support plate 12; the limiting cover plate 3 is semi-circular, and an L-shaped tightening insert 31 is provided circumferentially on the inner peripheral wall of the limiting cover plate 3 to lock into the L-shaped tightening slots 121. Through the rotational engagement of the L-shaped tightening insert 31 and the L-shaped tightening slots 121, it can be ensured that the limiting cover plate 3 is fixed to the outer annular support plate 12 when tightened, and at the same time, it can be easily unscrewed to disengage the limiting cover plate 3 from the outer annular support plate 12, improving the convenience of opening and locking the limiting cover plate 3 and ensuring the stability of locking.

[0030] like Figure 2As shown, the bottom surface of the outer annular support plate 12 is lower than the bottom surface of the inner annular support plate 13, and a height difference is formed between the outer annular support plate 12 and the inner annular support plate 13 for installing the lower powder outlet sealing plate 2. The thickness of the lower powder outlet sealing plate 2 matches the height difference between the outer annular support plate 12 and the inner annular support plate 13. An arc-shaped limiting opening 122 is provided circumferentially on the outer annular support plate 12 on the side facing the lower powder inlet 41 to restrict the rotation of the lower powder inlet sealing plate 2. The arc-shaped limiting opening 122 is a U-shaped groove with the opening facing upward. The two side walls of the arc-shaped limiting opening 122 are two limiting points. The bottom of the groove of the arc-shaped limiting opening 122 is flush with the bottom surface of the inner annular support plate 13. A stirring drive assembly 6 is installed in the inner annular support plate 13. The lower powder inlet sealing plate 2 is coaxially arranged and rotatably sleeved on the stirring drive assembly 6. The bottom surface of the lower powder inlet sealing plate 2 does not exceed the bottom surface of the outer annular support plate 12, so that the limiting cover plate 3 can limit the lower powder inlet sealing plate 2 within. The arc-shaped limiting opening 122 facilitates the rotation and limiting of the powder outlet sealing plate 2, thereby making it easier to position the powder outlet sealing plate 2 at the open limiting point at one end of the arc-shaped limiting opening 122 and at the closed limiting point at the other end, thus enabling the powder outlet sealing plate 2 to rotate to the designated state more accurately.

[0031] like Figure 1 and Figure 2 As shown, a radially inwardly protruding arc-shaped support plate 111 is provided at the bottom end of the side wall of the mounting groove 11, corresponding to the arc-shaped limiting opening 122. The rotation angle of the arc-shaped support plate 111 matches the rotation angle of the arc-shaped limiting opening 122. The bottom surface of the outer end of the extension 203 abuts against the top surface of the arc-shaped support plate 111, causing the outer end of the extension 203 to rotate along the arc-shaped support plate 111. The arc-shaped support plate 111 can support the outer end of the powder outlet sealing plate 2, ensuring that the powder outlet sealing plate 2 can rotate horizontally, while also ensuring the stability and connectivity of the rotation of the powder outlet sealing plate 2, thereby ensuring that the powder outlet sealing plate 2 always maintains a good sealing effect on the powder outlet 41.

[0032] like Figure 2 and Figure 3As shown, the stirring drive assembly 6 includes a rotating block 61, a bottom seal 62, a stirring shaft 63, and a stirring head 64 arranged coaxially. Both the rotating block 61 and the bottom seal 62 are cylindrical. The rotating block 61 is rotatably connected to the inner annular support plate 13 through the bottom seal 62. The lower end of the stirring shaft 63 is fixedly connected to the rotating block 61, and the upper end of the stirring shaft 63 extends through the mounting groove 11 into the powder storage chamber 10 of the milk powder box 1. The top end of the stirring shaft 63 is connected to the stirring head 64. The stirring head 64 is used to stir the milk powder in the powder storage chamber 10. The stirring drive assembly 6 also includes other conventional transmission components such as drive gears. A powder feeding screw is provided in the powder feeding chamber 4. The powder feeding screw is driven to rotate synchronously through the transmission components to achieve powder feeding. This is a conventional milk maker drive mechanism, which will not be described in detail here. The powder outlet sealing plate 2 is rotatably mounted on the rotating block 61. The powder outlet sealing plate 2 is disc-shaped, and a circular through hole 201 is provided in the middle of the powder outlet sealing plate 2 to rotatably engage with the stirring drive assembly 6. The transmission part is a drive positioning socket 202 provided on the powder outlet sealing plate 2 and connected to the circular through hole 201. The drive positioning socket 202 is used to engage with the drive positioning plug on the machine body to realize the rotation of the powder outlet sealing plate 2. A horizontal extension 203 is provided radially on one side of the outer wall of the powder outlet sealing plate 2. The extension 203 extends through the arc-shaped limiting opening 122 to the powder outlet 41. The drive positioning socket 202 facilitates the insertion and engagement with the drive positioning plug, thereby driving the drive positioning plug to rotate through the motor. The drive positioning plug on the machine body is rotated by the motor. This is a conventional drive mechanism and will not be described in detail here. This allows the powder outlet sealing plate 2 to rotate, enabling the extension 203 to cover or expose the powder outlet 41, ultimately closing or opening the powder outlet 41.

[0033] When this structure is in operation, the milk powder box 1 is inserted into the machine body, and the drive positioning plug is inserted into the drive positioning socket 202 of the powder outlet sealing plate 2. The motor inside the machine body drives the drive positioning plug to rotate, which in turn drives the powder outlet sealing plate 2 to rotate in the arc-shaped limiting opening 122. The powder outlet sealing plate 2 rotates to one side wall of the arc-shaped limiting opening 122, thus exposing the powder outlet 41 and opening the powder outlet 41 for easy powder dispensing. The powder outlet sealing plate 2 then rotates to the other side wall of the arc-shaped limiting opening 122, thus closing the powder outlet 41 and sealing it to prevent milk powder from leaking from the powder outlet 41. This also prevents the milk powder from getting damp inside the powder delivery chamber 40.

[0034] After a period of use, the powder outlet sealing plate 2 needs to be cleaned. During cleaning, the limiting cover plate 3 is rotated to disengage from the outer annular support plate 12, thereby removing the powder outlet sealing plate 2 from the rotating block 61. The powder outlet sealing plate 2 is then cleaned, and the sealing plug 5 is removed for cleaning or replacement. After cleaning, the powder outlet sealing plate 2 is reinstalled along the original path, and the limiting cover plate 3 is tightened and locked onto the outer annular support plate 12.

[0035] The advantage of this utility model is that the structure can easily limit and fix the powder outlet sealing plate 2 through the detachable limiting cover plate 3. It also makes it easy to remove the powder outlet sealing plate 2 for cleaning after the milk maker has been used for a period of time. This allows for the rinsing of milk powder residue and bacteria caused by moisture on the powder outlet sealing plate 2. It also solves the problem of poor sealing effect caused by milk powder accumulation on the powder outlet sealing plate 2, ultimately ensuring the hygiene of the powder outlet sealing plate 2 and the sealing effect of the powder outlet 41.
