Description

Technical Field

[0001] This invention relates to the field of kitchen utensils, and particularly to a milk maker. Background Technology

[0002] A typical formula maker consists of a water tank, a formula powder hopper, a mixing chamber, and a heating device. The formula powder hopper stores formula powder and is connected to the mixing chamber, supplying it with formula. The heating device heats the water in the water tank and then pours the hot water into the mixing chamber to prepare the formula.

[0003] Typically, a fan is installed above the mixing chamber of a formula maker. This fan draws air from the mixing chamber to remove moisture and prevent it from entering the milk powder compartment and affecting the milk powder inside. However, as the fan draws air from the milk powder compartment, some milk powder and warm moisture adhere to the fan, causing bacteria to grow and producing odors, thus affecting overall hygiene. Currently, formula makers do not have a cleaning mechanism for the fan, making it difficult to clean and impacting the user experience. Summary of the Invention

[0004] The purpose of this invention is to provide a milk maker that has the advantages of easy fan cleaning and improved hygiene conditions.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] This invention provides a formula preparation machine, comprising a housing, a mixing chamber, a milk powder chamber, and a fan assembly. The mixing chamber is disposed within the housing and is equipped with a water inlet for connecting to a water tank. The milk powder chamber is connected to the mixing chamber and is used to supply milk powder to the mixing chamber. The fan assembly is disposed within the mixing chamber and is used to extract moisture from the milk powder chamber. The formula preparation machine also includes a fan mounting base, which is fixedly disposed on the housing, and the fan assembly is detachably disposed on the fan mounting base.

[0007] The fan mounting base is provided with a first power supply component for connecting to a power source; the fan component includes a fan assembly and a second power supply component, the air inlet of the fan assembly is connected to the mixing chamber, and the air outlet of the fan assembly is connected to the outside; the second power supply component is electrically connected to the fan assembly, the first power supply component and the second power supply component are detachably arranged, and when the fan component is installed on the fan mounting base, the first power supply component and the second power supply component are electrically connected to supply power to the fan component.

[0008] In this design, the mixing chamber is supported by the casing. Milk powder from the powder container is introduced into the mixing chamber, and hot water is injected into the mixing chamber through the water inlet to mix and prepare the milk powder. A fan mounting base is installed on the casing, and the fan assembly is detachably mounted on the fan mounting base. The air inlet of the fan assembly is connected to the mixing chamber, and the air outlet is connected to the outside, so as to continuously draw moisture from the mixing chamber to the outside. When a lot of milk powder adheres to the fan assembly, the fan assembly can be removed from the fan mounting base for cleaning, preventing bacteria from growing and producing odors in a long-term humid environment, thereby improving the hygiene of the milk maker. The first power supply component on the fan mounting base and the second power supply component of the fan assembly are detachable. When the fan assembly is installed in the fan mounting base, the second power supply component is electrically connected to the first power supply component, allowing external power to supply power to the fan assembly. When the fan assembly is removed from the fan mounting base, the second power supply component is separated from the first power supply component and removed from the fan mounting base along with the fan assembly. This electrical connection method enables the fan assembly to be electrically connected and disconnected from external power sources under a detachable connection scheme between the fan assembly and the fan mounting base.

[0009] Preferably, the first power supply component includes a circuit board and two first contacts, the two first contacts being disposed on the circuit board and electrically connected to the circuit board; the second power supply component includes two second contacts, the second contacts being disposed on the fan assembly and electrically connected to the fan assembly; the first contacts and the second contacts correspond one-to-one, and the first contacts are capable of making contact with the second contacts to conduct electricity.

[0010] In this design, the two first contacts of the first power supply component correspond one-to-one with the two second contacts of the second power supply component. Thus, when the fan assembly is installed in the fan mounting base, the first and second contacts make contact to conduct current, allowing external power to flow through the circuit board, the two first contacts, and the two second contacts to form a power supply loop for the fan assembly. This electrical connection method is simple in structure; the first and second contacts make contact when the fan assembly is installed in the fan mounting base, making the connection convenient and requiring no additional operation.

[0011] Preferably, the first contact includes a contact base, a spring, and a movable contact pin. The contact base is fixed to the inner wall of the fan mounting base and electrically connected to the circuit board. The contact base has a movable groove on the side facing the second contact. The movable contact pin is slidably inserted into the movable groove and partially exposed outside the movable groove. The movable contact pin is electrically connected to the contact base. The spring is disposed in the movable groove and abuts against the movable contact pin and the bottom wall of the movable groove.

[0012] In this design, the movable contact pin of the first contact can slide relative to the contact base to change the total length of the first contact, facilitating contact between the first and second contacts. When the second contact contacts the first contact, the second contact abuts against the first contact, and the spring drives the movable contact pin to press against the second contact, making the first and second contacts tightly connected. This also reduces the accuracy requirements when the first and second contacts are in contact, making it easier to set the first and second contacts.

[0013] Preferably, the fan assembly includes a fan housing and an exhaust fan, the exhaust fan is installed inside the fan housing, the fan housing is detachably installed on the fan mounting base, and the air inlet and air outlet of the fan assembly are both formed in the fan housing.

[0014] In this design, the fan assembly includes an exhaust fan and a fan housing. The fan housing encloses the fan assembly, integrating the exhaust fan and the fan housing into a single unit for easy installation and disassembly. The air inlet and outlet of the fan assembly are formed on the fan housing, which creates a suitable flow path to guide air from the mixing chamber to the outside.

[0015] Preferably, a first magnetic attractor is provided inside the fan mounting base, and a second magnetic attractor is provided on the fan housing, with the first magnetic attractor and the second magnetic attractor magnetically attracted to each other.

[0016] In this solution, the fan housing is magnetically attracted to the first magnetic component via the second magnetic component, thereby connecting to the fan mounting base. When installing the fan assembly, simply align the fan housing with the fan mounting base, and the fan housing will automatically be attracted by the magnetic force. When disassembling the fan assembly, simply apply external force to pull the fan housing off the fan mounting base. The disassembly and assembly are simple and labor-saving, and the structure is simple and easy to manufacture.

[0017] Preferably, the exhaust fan is provided with a positioning sleeve, which is fixedly sleeved on the outside of the second contact. The length of the positioning sleeve is greater than the length of the second contact. The positioning sleeve passes through the fan housing and abuts against the inner wall of the fan mounting base. The first contact passes through the positioning sleeve and contacts the second contact.

[0018] In this design, a positioning sleeve is fitted over the second contact, and the first contact passes through the positioning sleeve to contact the second contact. The positioning sleeve positions the first and second contacts, ensuring alignment and contact between them when the fan assembly is installed on the fan mounting base. It also positions the fan assembly and mounting base during installation, facilitating connection. The positioning sleeve also fits over both the first and second contacts and abuts against the inner wall of the fan mounting base, separating them from other parts of the fan housing. This prevents the humid air drawn from the mixing chamber by the fan from directly contacting the first and second contacts and affecting their normal operation.

[0019] Preferably, the fan housing includes an upper housing and a lower housing, the upper housing and the lower housing are detachably connected, and the exhaust fan is disposed between the upper housing and the lower housing.

[0020] In this design, the fan housing encloses the exhaust fan through detachable upper and lower housings, allowing the fan assembly to be disassembled for cleaning, thus facilitating cleaning and assembly of the fan assembly.

[0021] Preferably, the housing includes a vertical support portion and a horizontal mounting portion, the horizontal mounting portion being connected to the vertical support portion and extending horizontally, and the mixing chamber being detachably disposed on the horizontal mounting portion;

[0022] The horizontal installation section is provided with an installation opening, the mixing chamber is located below the installation opening, the fan mounting base is located above the installation opening, and the fan assembly fits into the installation opening.

[0023] In this design, the mixing chamber is installed below the installation opening, and the fan mounting base is located above the installation opening. That is, the fan assembly is installed above the mixing chamber and draws water vapor from the mixing chamber from above. The fan assembly fits into the installation opening, making the overall structure more compact when the fan assembly is installed on the fan mounting base on the casing. At the same time, it ensures that the air flows strictly from the air inlet to the air outlet of the fan assembly, making it easier to control the airflow direction.

[0024] Preferably, a drawer base is connected to the outside of the mixing compartment; one of the horizontal mounting part and the drawer base is provided with a guide groove, and the other of the horizontal mounting part and the drawer base is provided with a guide rail, the guide groove being adapted to the guide rail; the guide groove is capable of sliding along the guide rail and disengaging from the guide rail.

[0025] In this design, the mixing compartment is horizontally mounted on the horizontal installation section via a drawer seat. When mixing formula, the drawer seat is pushed along the guide rail to align the mixing compartment below the mounting opening with the air inlet of the fan assembly. When the mixing compartment needs to be removed, the drawer seat is pulled in the opposite direction to detach it from the horizontal installation section. This method of assembling and disassembling the mixing compartment is simple and convenient.

[0026] Preferably, the drawer seat is connected to a handle component, the handle component is disposed on the outside of the drawer seat, the handle component includes a baffle and a connecting plate, the connecting plate is connected to the drawer seat, the baffle is vertically disposed on the side of the connecting plate away from the drawer seat; the portion of the connecting plate near the baffle is provided with a through hole penetrating the connecting plate, the through hole communicating with the air outlet of the fan assembly.

[0027] In this design, a handle is attached to the outside of the drawer seat for easy pushing and pulling. The handle's connecting plate has a through hole, allowing the user to insert their fingers and apply force to the handle. This through hole also connects to the fan assembly's exhaust vent, guiding the air exhausted by the fan assembly out through the handle. Compared to methods where the air drawn by the fan assembly is exhausted elsewhere, both the drawer seat and handle can be removed from the casing, making cleaning easier even if milk powder adheres to them. A baffle is attached to the connecting plate, facilitating the user's pushing and pulling of the drawer seat while simultaneously blocking the fan assembly's exhaust air, preventing it from blowing directly at the user and affecting their experience.

[0028] In summary, the present invention has the following beneficial effects:

[0029] In this invention, the fan assembly is detachably mounted on the fan mounting base to continuously draw moisture from the mixing chamber to the outside. When a large amount of milk powder adheres to the fan assembly, the fan assembly can be removed from the fan mounting base for cleaning, preventing the milk powder on the fan assembly from breeding bacteria and producing odors in a long-term humid environment, thereby improving the hygiene conditions of the milk maker. The first power supply component on the fan mounting base and the second power supply component of the fan assembly are detachably configured. This electrical connection method enables the fan assembly to be electrically connected and disconnected from the external power source under the detachable connection scheme between the fan assembly and the fan mounting base.

[0044] The invention will now be further described with reference to the accompanying drawings.

[0045] This embodiment discloses a formula maker 1000, referring to... Figure 1 , Figure 2 and Figure 5 The formula maker 1000 includes a housing 100, a mixing chamber 200, a milk powder chamber 300, and a fan assembly 400. The mixing chamber 200 is located on the housing 100 and has a water inlet 250 for connecting to a water tank. The milk powder chamber 300 is located on the housing 100 and connected to the mixing chamber 200, and is used to supply milk powder to the mixing chamber 200. The fan assembly 400 is located in the mixing chamber 200 and is used to remove moisture from the milk powder chamber 300.

[0046] Preferably, the housing 100 also includes a water tank and a heating mechanism. The water tank is connected to the water inlet connector 250 to provide hot water to the mixing chamber 200. The heating mechanism is located in the water tank to heat the water in the tank. The mixing chamber 200 is supported by the housing 100. Milk powder from the milk powder compartment 300 is introduced into the mixing chamber 200, and hot water is injected into the mixing chamber 200 through the water inlet connector 250 to mix and prepare the milk powder.

[0047] Reference Figure 1 and Figure 2The housing 100 includes a decorative outer shell 110, a display screen 120, a vertical support portion 130, and a horizontal mounting portion 140. The decorative outer shell 110 is fixed to the outside of the vertical support portion 130 and the horizontal mounting portion 140 for decorative purposes. The display screen 120 is mounted on the decorative outer shell 110 to display parameters such as temperature and water volume when preparing milk powder. The vertical support portion 130 is vertically positioned, and the horizontal mounting portion 140 is connected to the upper part of the vertical support portion 130 and extends horizontally outward from the housing 100.

[0048] In this embodiment, the vertical support portion 130 is recessed to form a vertically extending groove, thereby providing space for the installation of the mixing chamber 200 and the placement of the milk powder bottle. The horizontal mounting portion 140 is horizontally connected to the upper opening of the groove formed by the vertical support portion 130, for the installation of the mixing chamber 200.

[0049] Reference Figures 2 to 5 In this embodiment, the horizontal mounting portion 140 is a shell-shaped component, and a mounting groove 141 is formed by an upward recess in the middle of the horizontal mounting portion 140, in which the mixing chamber 200 is installed.

[0050] The mounting groove 141 extends horizontally, and an opening connecting to the outside is formed on the side of the mounting groove 141 away from the vertical support. A drawer seat 500 is externally connected to the mixing chamber 200. The drawer seat 500 can slide along the length of the mounting groove 141 to drive the mixing chamber 200 to be installed on or removed from the horizontal mounting portion 140.

[0051] Specifically, in this embodiment, guide grooves 510 are provided on both sides of the drawer base 500, and guide rails 142 are provided on the opposite side walls of the mounting groove 141. The guide rails 142 and guide grooves 510 are arranged parallel to the length direction of the mounting groove 141. The guide grooves 510 and guide rails 142 are adapted to each other, that is, the guide rails 142 can pass through the guide grooves 510 to support the drawer base 500, and the guide grooves 510 can slide along the guide rails 142 and disengage from the guide rails 142.

[0052] Thus, the mixing chamber 200 is horizontally slidably mounted on the horizontal mounting portion 140 via the drawer seat 500. When it is necessary to prepare milk powder, the drawer seat 500 is pushed to slide along the guide rail 142, so that the mixing chamber 200 is installed in the set position on the mounting slot 141. When it is necessary to remove the mixing chamber 200, the drawer seat 500 is pulled in the opposite direction to detach the drawer seat 500 and the mixing chamber 200 from the horizontal mounting portion 140. The assembly and disassembly of the mixing chamber 200 is simple and convenient.

[0053] In this embodiment, the mixing chamber 200 and the drawer base 500 are integrally formed to make the overall structure more compact. In other embodiments, the mixing chamber 200 and the drawer base 500 may also be formed separately and then connected together.

[0054] In this embodiment, refer to Figure 5 and Figure 6 The mixing chamber 200 is a funnel-shaped component with an independent milk powder inlet 210 and an air outlet 220 at its upper part (larger diameter end). The milk powder inlet 210 is connected to the milk powder hopper 300 and is used to supply milk powder into the mixing chamber 200. The air outlet 220 is directly opposite the fan assembly 400 and is used by the fan to draw moisture from the mixing chamber 200. The lower part (smaller diameter end) of the mixing chamber 200 has a discharge port 230, and the inner wall of the mixing chamber 200 is provided with spiral ribs 240. Milk powder and water enter the mixing chamber 200 and rotate under the guidance of the spiral ribs 240 to be fully mixed. The mixed milk powder is discharged from the mixing chamber 200 through the discharge port 230 for user use.

[0055] Reference Figures 2 to 7 In this embodiment, the fan assembly 400 is disposed above the mixing chamber 200. Specifically, the horizontal mounting portion 140 has a mounting opening 143 on the upper sidewall of the mounting groove 141. The mixing chamber 200 is disposed below the mounting opening 143 and closely abuts the upper sidewall of the mounting groove 141, and the air outlet 220 of the mixing chamber 200 communicates with the mounting opening 143. The fan assembly 400 passes through the mounting opening 143 and is disposed above the horizontal mounting portion 140.

[0056] A fan mounting base 600 is fixedly installed on the upper side of the horizontal mounting portion 140. The fan mounting base 600 is a hollow, cover-like component, which covers the mounting opening 143 and the opening of the fan mounting base 600 is directly opposite the mounting opening 143. The fan assembly 400 is detachably installed in the fan mounting base 600.

[0057] Reference Figures 7 to 10 The fan mounting base 600 is equipped with a first power supply component 610 for connecting to a power source; the fan assembly 400 includes a fan assembly 410 and a second power supply component 420. The fan assembly 410 has an air inlet 430 and an air outlet 440, and the fan assembly 410 is capable of drawing air in through the air inlet 430 and expelling air through the air outlet 440. The air inlet 430 of the fan assembly 410 is connected to the mixing chamber 200, and the air outlet 440 of the fan assembly 410 is connected to the outside. The second power supply component 420 is electrically connected to the fan assembly 410, and the first power supply component 610 and the second power supply component 420 are detachably configured.

[0058] When a lot of milk powder adheres to the fan assembly 410, the fan component 400 can be removed from the fan mounting base 600 for cleaning. This prevents the milk powder on the fan assembly 410 from breeding bacteria and producing odors in a long-term humid environment, thereby improving the hygiene conditions of the milk maker 1000.

[0059] The first power supply component 610 on the fan mounting base 600 and the second power supply component 420 of the fan assembly 400 are detachably configured. When the fan assembly 410 is installed in the fan mounting base 600, the second power supply component 420 is electrically connected to the first power supply component 610, allowing external power to supply power to the fan assembly 410. When the fan assembly 410 is removed from the fan mounting base 600, the second power supply component 420 is separated from the first power supply component 610 and is removed from the fan mounting base 600 along with the fan assembly 410. This electrical connection method enables the fan assembly 400 to be electrically connected and disconnected from external power sources under a detachable connection scheme between the fan assembly 400 and the fan mounting base 600.

[0060] In this embodiment, the first power supply component 610 includes a circuit board 611 and two first contacts 612. The circuit board 611 is disposed on the outer side of the fan mounting base 600 away from the mounting opening 143 and is connected to an external power source. The two first contacts 612 are disposed through the fan mounting base 600 and are electrically connected to the circuit board 611. The second power supply component 420 includes two second contacts 421, which are disposed on the fan assembly 410 and electrically connected to the fan assembly 410. The first contacts 612 and the second contacts 421 correspond one-to-one. When the fan assembly 400 is installed in the fan mounting base 600, the first power contacts and the second contacts 421 contact to conduct current, thereby forming a circuit for powering the fan assembly 410 through the circuit board 611, the two first contacts 612, and the two second contacts 421. This type of electrical connection has a simple structure. When the fan assembly 400 is installed on the fan mounting base 600, the first contact 612 and the second contact 421 make contact and conduction is achieved. The connection is convenient and requires no additional operation.

[0061] In addition, in other embodiments, the first power supply component 610 and the second power supply component 420 may also adopt other structures, such as using mutually mating plugs for electrical connection.

[0062] Combination Figure 11 and Figure 12In this embodiment, the first contact 612 includes a contact base 6121, a spring 6122, and a movable contact pin 6123. The contact base 6121 is fixed to the inner wall of the fan mounting base 600 and passes through the fan mounting base 600 to be electrically connected to the circuit board 611. The contact base 6121 has a movable groove 6124 on the side facing the second contact 421. The movable contact pin 6123 is slidably inserted into the movable groove 6124, with a portion of the movable contact pin 6123 protruding outside the movable groove 6124. The movable contact pin 6123 contacts the inner wall of the movable groove 6124 to maintain the movable contact pin 6123 electrically connected to the contact base 6121. The spring 6122 is disposed in the movable groove 6124 and abuts against the movable contact pin 6123 and the bottom wall of the movable groove 6124.

[0063] The movable contact pin 6123 of the first contact 612 can slide relative to the contact base 6121, allowing the overall length of the first contact 612 to vary. If the length of the first contact 612 is fixed, it must be ensured that when the fan assembly 400 is installed in the fan mounting base 600, the first contact 612 is in direct contact with the second contact 421. This requires high machining precision for the first contact 612 and the second contact 421. If the lengths of the first contact 612 and the second contact 421 are too small, there will be a gap between them, preventing current from flowing between them. If the lengths of the first contact 612 and the second contact 421 are too large, the first contact 612 and the second contact 421 are easily damaged during the installation of the fan assembly 400, and the fan assembly 400 may not be installed properly. The technical solution of this embodiment facilitates the contact between the first contact 612 and the second contact 421. When the second contact 421 contacts the first contact 612, the second contact 421 abuts against the first contact 612, and the spring 6122 drives the movable contact pin 6123 to press against the second contact 421, so that the first contact 612 and the second contact 421 are in close contact. At the same time, the accuracy requirement when the first contact 612 and the second contact 421 are reduced, which facilitates the setting of the first contact 612 and the second contact 421.

[0064] Reference Figure 7 The fan assembly 410 fits into the mounting opening 143. This makes the overall structure more compact when the fan assembly 410 is mounted on the fan mounting bracket 600 on the housing 100, and at the same time makes the air flow from the air inlet 430 to the air outlet 440 of the fan assembly 410, which is convenient for controlling the air flow direction.

[0065] Reference Figure 8 and Figure 9In this embodiment, the fan assembly 410 includes a fan housing 411 and an exhaust fan 412. The exhaust fan 412 is installed inside the fan housing 411, which is detachably installed on the fan mounting base 600. The fan housing 411 encloses the fan assembly 410, and integrates the exhaust fan 412 and the fan housing 411 into a single unit for easy installation and removal. The air inlet 430 and air outlet 440 of the fan assembly 410 are both formed within the fan housing 411.

[0066] The fan housing 411 includes an upper housing 4111 and a lower housing 4112, which are detachably connected. The exhaust fan 412 is disposed between the upper housing 4111 and the lower housing 4112. The fan housing 411 encloses the exhaust fan 412 through the detachable upper housing 4111 and lower housing 4112, thereby allowing the fan assembly 410 to be disassembled for cleaning, facilitating the cleaning and assembly of the fan assembly 410.

[0067] In this embodiment, the upper housing 4111 and the lower housing 4112 are connected by a snap-fit ​​mechanism. However, in other embodiments, the upper housing 4111 and the lower housing 4112 may be connected using other suitable methods.

[0068] The shaft of the exhaust fan 412 is vertically oriented. An upper housing 4111 covers the upper side of the exhaust fan 412, and an air guide 4113 is located on the front side of the upper housing 4111 (the side closest to the user). The lower housing 4112 is fitted into the mounting opening 143 (meaning the shape and size of the lower housing 4112 match the mounting opening 143). The air inlet 430 and air outlet 440 of the fan assembly 410 are both located on the lower housing 4112. When the exhaust fan 412 operates, air in the mixing chamber 200 flows sequentially through the air outlet 220 and the air inlet 430 to the exhaust fan 412, is then blocked and deflected by the upper housing 4111, blown out through the air guide 4113, and finally flows out through the air outlet 440.

[0069] Reference Figure 9 and Figure 12 Two positioning sleeves 413 are provided on the exhaust fan 412. The two positioning sleeves 413 are fixed to the middle of the exhaust fan 412 and respectively sleeved on the outside of the second contact 421. The length of the positioning sleeve 413 is greater than the length of the second contact 421, and the positioning sleeve 413 passes through the fan housing 411. The end of the positioning sleeve 413 away from the exhaust fan 412 abuts against the inner wall of the fan mounting base 600, and the first contact 612 passes through the positioning sleeve 413 and contacts the second contact 421.

[0070] Therefore, by positioning the first contact 612 and the second contact 421 using the positioning sleeve 413, it is ensured that when the fan assembly 400 is installed on the fan mounting base 600, the first contact 612 and the second contact 421 are aligned and in contact. Simultaneously, it also positions the fan assembly 400 and the fan mounting base 600 during installation, facilitating the connection between them. The positioning sleeve 413 is also fitted over the first contact 612 and the second contact 421 and abuts against the inner wall of the fan mounting base 600, separating the first contact 612 and the second contact 421 from other parts of the fan housing 411. This prevents water vapor drawn from the mixing chamber 200 from directly contacting the first contact 612 and the second contact 421, thus avoiding oxidation of the first contact 612 and / or the second contact 421 and affecting their normal operation.

[0071] Reference Figure 8 and Figure 9 In this embodiment, a first magnetic 620 is provided inside the fan mounting base 600, and a second magnetic 4114 is provided on the upper side of the upper housing 4111. The first magnetic 620 and the second magnetic 4114 are magnetically attracted to each other. When installing the fan assembly 400, simply align the fan housing 411 with the fan mounting base 600, and the fan housing 411 will automatically be attracted by magnetic force. When disassembling the fan assembly 400, simply apply external force to pull the fan housing 411 off the fan mounting base 600. The assembly and disassembly are simple and labor-saving, and the structure is simple and easy to manufacture.

[0072] In this embodiment, both the first magnetic attractor 620 and the second magnetic attractor 4114 are magnets, and the magnetic poles of the first magnetic attractor 620 and the second magnetic attractor 4114 on opposite sides are different. In other embodiments, one of the first magnetic attractor 620 and the second magnetic attractor 4114 is a magnet, and the other is a ferromagnetic component that can be attracted by a magnet.

[0073] In this embodiment, multiple first magnetic 620s and second magnetic 4114s are provided, specifically shown with three first magnetic 620s and three second magnetic 4114s. The upper housing 4111 has three first grooves 630 on the side facing the fan mounting base 600, and the inner wall of the fan mounting base 600 has three second grooves 4115 corresponding to the first grooves 630 on the side facing the upper housing 4111. The first magnetic 620s are fitted and fixed in the first grooves 630, and the second magnetic 4114s are fitted and fixed in the second grooves 4115.

[0074] In addition, in other embodiments, the fan assembly 400 may also be detachably connected to the fan mounting base 600 by a suitable method such as snap-fit ​​or bolt connection.

[0075] Reference Figure 5 and Figure 7In this embodiment, a handle component 700 is connected to the drawer seat 500. The handle component 700 is located on the outside of the drawer seat 500 (i.e., the side of the drawer seat 500 facing the user) to facilitate the user pushing and pulling the drawer seat 500. The handle component 700 includes a baffle 710 and a connecting plate 720. The connecting plate 720 is horizontally connected to the drawer seat 500, and the baffle 710 is vertically located on the side of the connecting plate 720 away from the drawer seat 500.

[0076] A weight-reducing cavity 721 is formed on the connecting plate 720 to reduce its weight while maintaining structural strength. The air outlet 440 on the lower housing 4112 is positioned directly opposite the connecting plate 720, and the weight-reducing cavity 721 connects to the air outlet 440. A through hole 722 is provided on the connecting plate 720 near the baffle 710, penetrating the connecting plate 720 and communicating with the weight-reducing cavity 721, allowing the user to insert their fingers and apply force to the handle component 700. This through hole 722 connects to the air outlet 440 of the fan assembly 410 through the weight-reducing cavity 721, guiding the air exhausted by the fan assembly 410 to exit from the handle component 700. Therefore, compared to the method where the air drawn by the fan assembly 410 is exhausted elsewhere, since both the drawer seat 500 and the handle component 700 can be removed from the housing 100, they are easy to clean even if milk powder adheres to them. The baffle 710 is connected to the connecting plate 720 to facilitate the user to push and pull the drawer seat 500. At the same time, the baffle 710 blocks the air exhausted from the fan assembly 410 to prevent the exhausted air from blowing directly at the user and affecting the user's experience.

[0077] The implementation principle of the milk maker 1000 in this embodiment is as follows:

[0078] When a significant amount of milk powder adheres to the fan assembly 400, the user pulls the drawer seat 500, causing the mixing chamber 200 to slide off the housing 100, exposing the mounting opening 143. The user then pulls the fan assembly 400 downwards through the mounting opening 143, disengaging it from the fan mounting base 600, thus disassembling the fan assembly 400. The fan assembly 400 can be further disassembled for cleaning, and both the drawer seat 500 and the handle component 700 can be removed from the housing 100 for easy cleaning.

[0079] After cleaning the fan assembly 400, insert it into the fan mounting base 600 through the mounting opening 143. The lower housing 4112 mates with the mounting opening 143, and the first magnetic member 620 magnetically attracts the second magnetic member 4114 to attach the fan assembly 400 to the fan mounting base 600. The first contact 612 contacts the second contact 421, thereby supplying power to the fan assembly 400. Align the slide groove on the drawer seat 500 with the slide rail on the housing 100, and push the drawer seat 500 inward to install the mixing chamber 200 into the housing 100, completing the installation of the fan assembly 400 and the mixing chamber 200.

[0080] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included in the scope of this patent application.
