Description

Technical Field

[0001] This utility model relates to the field of formula preparation technology, specifically a formula preparer. Background Technology

[0002] In modern childcare, the feeding needs of infants and young children place high demands on the accuracy and convenience of water temperature control. As a popular modern maternal and infant product, existing bottle warmers can maintain a constant water temperature within the suitable range for infants and young children, greatly satisfying parents' needs for instant preparation and avoiding problems such as long cooling times and difficulty in controlling water temperature that occur when preparing formula, thus providing convenience for infant feeding.

[0003] However, after a formula maker finishes dispensing water, there is usually water residue in the outlet pipes, which is drained during the next dispensing process. If there is a long interval between two uses of the formula maker, this drainage method may result in the water temperature dispensing the next batch of formula not matching the preset value.

[0004] To address the aforementioned issues, some formula makers on the market are equipped with a water tank to collect water remaining in the outlet pipe after dispensing. However, users may fail to empty the tank promptly, leading to overflow. While some products feature a water level observation window, this relies on user monitoring and lacks real-time feedback, resulting in insufficient ease of use. Furthermore, the water tanks in most existing formula makers are located at the bottom, which can be inconvenient and prone to spillage when users need to remove the tank for emptying or cleaning. Utility Model Content

[0005] To address the above problems, this utility model provides a formula maker that not only allows users to easily disassemble and assemble the water tank used to collect residual water in the water outlet pipe, but also promptly notifies users to empty the remaining water in the tank to prevent overflow.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] This embodiment provides a formula maker 100. Figure 1 This is a front view of the structure of a formula maker 100 provided in this embodiment. Figure 2 This is a cross-sectional view of the structure of a formula maker 100 provided in this embodiment, combined with... Figure 1 and Figure 2As shown, the formula maker 100 includes a bottle holder 111, a shaking mechanism 2, a dispensing mechanism 3, and a heater 4. The bottle holder 111 is used to place and secure a bottle (not shown in the figure); the shaking mechanism 2 is connected to the bottle holder 111 and shakes the bottle via the bottle holder 111; the dispensing mechanism 3 has a corresponding dispensing port 32 located above the bottle holder 111, and is configured to supply liquid to the bottle via the dispensing port 32; the heater 4 is configured to heat the bottle in the bottle holder 111.

[0041] In this embodiment, by integrating components such as the bottle holder 111, the shaking mechanism 2, the dispensing mechanism 3, and the heater 4 into the formula maker 100, the formula maker 100 simultaneously possesses dispensing, mixing, and heating / keeping functions. Users can personalize the operating status and time of the formula maker 100 according to their actual needs. They can independently control the dispensing, mixing, and heating / keeping functions of the formula maker 100, or freely combine these three functions to allow them to operate synergistically.

[0042] refer to Figure 1 and Figure 2 In this embodiment, the formula maker 100 has a first control panel 1A above the outer surface of its housing 1 for controlling the dispensing mechanism 3; and a second control panel 1B below the outer surface of its housing 1 for controlling the shaking mechanism 2, the heater 4, and other components for heating and heat preservation. The buttons / touchscreens on the surfaces of the first control panel 1A and the second control panel 1B are all oriented towards the side where it is convenient for the user to insert the bottle, improving ease of operation.

[0043] Taking the use of formula feeding for infants as an example, after placing the bottle in the preset position of the bottle holder 111 of the formula maker 100 and securing it, the user can adjust the dispensing parameters by controlling the buttons on the surface of the first control panel 1A, causing the dispensing mechanism 3 to add a preset volume of water to the bottle located directly below it. After the dispensing process is completed, the user first adds an appropriate amount of formula to the bottle and installs the matching bottle cap on the bottle opening to prevent milk from spilling onto the surface and interior of the formula maker 100 during subsequent operations, causing equipment damage or a mess. Subsequently, the shaking mechanism 2 of the formula maker 100 can be automatically activated or manually activated by controlling the buttons / touchscreen of the second control panel 1B, causing the bottle located in the bottle holder 111 to mechanically rotate or shake. The frequency and amplitude of the rotation or shaking can be set by the user by pressing the second control panel 1B. Compared to manual shaking, the mixing function of the formula maker 100 provided in this embodiment makes the mixing process more uniform and efficient, ensuring that the formula powder in the bottle is fully dissolved.

[0044] In this embodiment, the heater 4 heats the bottle in the bottle holder 111, i.e., heats and keeps the milk warm. When the water temperature supplied to the bottle by the dispensing mechanism 3 is too low, or when the milk temperature drops below the suitable drinking temperature range for infants during shaking, the heater 4 can be automatically activated, or manually activated via the second control panel 1B. The heater 4 and other heating and warming components in the above heating and warming process can operate independently or simultaneously with the shaking mechanism 2. Through this embodiment, after the shaking process of the formula maker 100 is completed, the temperature of the bottle and the milk remains within the suitable drinking temperature range for infants. At this time, after the user removes the bottle from the bottle holder 111, the infant can be fed directly. Furthermore, in cases where the entire bottle of milk is not fed at once, the user can place the bottle containing the remaining milk in the bottle holder 111, and then restart the shaking mechanism 2 and the heater 4 to reheat the remaining milk to the suitable drinking temperature range for infants and keep it warm.

[0045] The formula maker 100 provided in this embodiment not only simultaneously has the functions of formula preparation, shaking, and heating / keeping warm, but also meets the diverse needs of users. Its integrated design makes the formula maker 100 compact, reducing its space occupation, and can meet the requirements of different usage scenarios. To ensure that the water discharged from the dispensing mechanism 3 accurately and smoothly falls into the bottle placed in the bottle holder 111, and to ensure that the bottle remains in the preset position of the bottle holder 111 during the shaking and heating / keeping warming functions of the formula maker 100, in this embodiment, the bottle holder 111 includes a bottle basket 1111 and multiple spring clips 1115. (Reference) Figure 2 and Figure 3The bottle basket 1111 has a first receiving cavity 1112 for accommodating the bottle, with the center of the opening of the first receiving cavity 1112 directly opposite the liquid outlet 32 ​​above it. One end of a spring clip 1115 is connected to the top periphery of the bottle basket 1111, and the other end extends radially inward. The bottle is configured to be inserted into the area enclosed by the central portion of the spring clips 1115 and held and fixed by the spring clips 1115. The spring clips 1115 are made of elastically deformable plastic or metal. When the bottle is not yet inserted into the first receiving cavity 1112 of the bottle basket 1111, the cross-sectional area enclosed by the inwardly extending end of the spring clip 1115 is smaller than the horizontal cross-sectional area when the bottle is placed vertically. When the bottle is inserted into the first receiving cavity 1112 of the bottle basket 1111, the inwardly extending ends of the multiple spring pieces 1115 are squeezed by the bottle, moving closer to the bottom and sidewalls of the first receiving cavity 1112. This causes the spring pieces 1115 to generate elastic potential energy toward the center of the first receiving cavity 1112. By applying horizontally opposite and equal elastic forces to the bottle through the multiple spring pieces 1115, the bottle can be firmly clamped in the center of the first receiving cavity 1112 of the bottle basket 1111, ensuring that the water flowing out through the outlet 32 ​​can fall vertically into the bottle. Preferably, the bottle holder 111 has four spring pieces 1115 evenly distributed along the top periphery of the bottle basket 1111. Of course, the number of spring pieces 1115 is not limited to four. To prevent the inwardly extending end of the spring 1115 from scratching the outer surface of the bottle when it is inserted into the bottle basket 1111, and to make the insertion process smoother, in this embodiment, the end of the spring 1115 that connects to the top periphery of the bottle basket 1111 is higher than its inwardly extending end, so that the spring 1115 forms an inclined guide surface for guiding the bottle downwardly. The inwardly extending end of the spring 1115 is provided with a downwardly smoothly extending edge portion 11151. The surface of the edge portion 11151 is arc-shaped to fit the outer surface of the bottle, increasing the contact area with the bottle surface and improving the installation stability of the bottle.

[0046] Because the formula warmer 100 provided in this embodiment has its own heating and heat preservation function, the spring 1115 inside the bottle basket 1111 may easily age due to prolonged exposure to high temperatures, causing a decrease in the clamping performance of the spring 1115 on the bottle. This can lead to a change in the clamping position of the bottle during the shaking process or the bottle being thrown directly out of the bottle basket 1111. To address this, the formula warmer 100 of this embodiment also includes a double torsion spring 1116, as described above. Figure 3 and Figure 4 The spring 1115 is connected to the top periphery of the bottle basket 1111 by a double torsion spring 1116. Specifically, refer to... Figure 4 and Figure 5The double torsion spring 1116 is made of a metal material with good elasticity and includes a U-shaped torsion frame 11164, a first torsion spring 11161, and a second torsion spring 11162. The first torsion spring 11161 and the second torsion spring 11162 are respectively provided on both sides of the torsion frame 11164. Torsion bars 11163 are provided on the side of the first torsion spring 11161 away from the torsion frame 11164 and the side of the second torsion spring 11162 away from the torsion frame 11164. The torsion frame 11164 is engaged with a torsion spring mounting member 1114 provided above the side wall of the bottle basket 1111. In this embodiment, the two torsion bars 11163 abut against the lower surface edges of the spring piece 1115. When the baby bottle is inserted into the bottle basket 1111, the pressed-down spring 1115 pushes the torsion bar 11163 downwards, causing the first torsion spring 11161 and the second torsion spring 11162 to twist and deform with the torsion bracket 11164, thereby converting the external force applied by the baby bottle into elastic potential energy. During the insertion process, the double torsion spring 1116 and the spring 1115 together apply elastic force to the baby bottle, thus firmly clamping the baby bottle in the bottle basket 1111. Even if the spring 1115 ages, the double torsion spring 1116 still has good elastic restoring ability and continues to push the spring 1115 to clamp the baby bottle. Compared with a single torsion spring, the double torsion spring 1116 has a higher load capacity and stronger torque output, improving the service life of the spring 1115; preferably, refer to Figure 2 and Figure 12 The bottle holder 11 has a bottle clamping sleeve 1115A snapped onto its top. The inner ring of the bottle clamping sleeve 1115A also includes multiple spring pieces 1115. The torsion spring mounting member 1114 is a groove structure adapted to the shape of the double torsion spring 1116. The groove structure is detachably installed on the bottle clamping sleeve 1115A. The torsion bar 11163 abuts against the lower surface of the spring pieces 1115. To achieve the heating and heat preservation function, in this embodiment, the side wall of the bottle basket 1111 has grid holes 1113, and the formula maker 100 also includes a fan 5. (Reference) Figure 2 and Figure 3 Hot air, generated by heater 4, is blown into bottle basket 1111 through grille holes 1113 by fan 5 to heat the bottles. To make the heating and heat preservation process of formula 100 more efficient and the temperature of the milk more uniform, the cross-sectional shape of grille holes 1113 in this embodiment is rectangular, located at the bottom of the side wall of bottle basket 1111, and evenly arranged in a ring. In other embodiments, the cross-sectional shape and size of grille holes 1113 are not specifically limited.

[0047] In this embodiment, the dispensing mechanism 3 includes a kettle 31, a dispensing pipe (not shown in the figure), and a hot water mechanism. The hot water mechanism heats the water in the kettle 31, and the dispensing pipe connects the kettle 31 and the dispensing port 32. Specifically, after the water in the kettle 31 is heated to boiling, it can be temporarily stored in the kettle 31 to cool down for later use. More preferably, after the water in the kettle 31 has boiled and cooled to 40℃-50℃, the water in the kettle 31 is added to the baby bottle through the dispensing mechanism 3. Using water at this temperature to prepare the milk powder can, on the one hand, prevent the active ingredients in the milk powder from becoming ineffective at high temperatures, and on the other hand, it can help the milk powder dissolve more quickly and evenly. In addition, since the optimal temperature for infant formula is 45℃, using drinking water cooled to 40℃-50℃ to prepare the milk powder can quickly bring the milk powder to the optimal drinking temperature for infants.

[0048] To allow users to clearly understand the real-time temperature of the milk, in this embodiment, a temperature sensing element 7 is also provided in the bottle holder 111 for detecting the temperature of the bottle. (Reference) Figure 3 and Figure 6 The temperature sensing element 7 is located at the center of the bottom of the bottle basket 1111. When the bottle is fully inserted into the bottle basket 1111 and firmly held, the temperature sensing element 7 measures the temperature of the bottom of the bottle, allowing the user to accurately determine whether the milk has reached the preset temperature. Preferably, the temperature sensing element 7 is an infrared sensor. In other embodiments, other temperature sensing devices can be used, and no specific limitations are imposed here. (Reference) Figure 6 Surrounding the temperature sensing element 7, an O-ring 8 and a support structure 81 are also provided. The O-ring 8 and the support structure 81 are tightly fitted to prevent hot air and water from entering the location of the temperature sensing element 7, thereby improving the accuracy of temperature detection.

[0049] To improve heating and heat preservation efficiency, and to fully utilize the internal space of the formula maker 100 to achieve miniaturization, in this embodiment, as follows: Figure 2 As shown, the fan 5 is located at the bottom of the upper housing 12, forming a first air duct 5A from the connection between the upper housing 12 and the base 11 to the bottle holder 111. The heater 4 is located within the first air duct 5A. The air inlet 51 of the fan 5 is located adjacent to or corresponding to the kettle 31, and the upper housing 12 has corresponding air inlets. When the kettle 31 contains hot water, the air surrounding the kettle 31 is heated. (Reference) Figure 2 and Figure 3 As the heating and heat preservation function of the formula maker 100 is activated, hot air around the kettle 31 is drawn into the first air duct 5A through the air inlet 51. After being reheated by the heater 4, the warm air passes through the grille holes 1113 to heat and keep the bottles in the bottle basket 1111 warm. (Reference) Figure 2 , Figure 3 and Figure 7 The air outlet 52 of the first air duct 5A is connected to the outer shell 1117 surrounding the bottle basket 1111. Warm air, input by the fan 5 and heated by the heater 4, enters the second air duct 5B between the outer shell 1117 and the grille hole 1113 of the bottle basket 1111 through the air outlet 52. The warm air then passes through the grille hole 1113 via the second air duct 5B to heat the bottles inside the bottle basket 1111. In this embodiment, the larger air outlet 52 ensures that the warm air entering the second air duct 5B of the bottle basket 1111 is split into two or three airflows, flowing towards the left and right sides of the air outlet 52 horizontally, circulating around the circumference of the bottle basket 1111, or overflowing from above the second air duct 5B. Technicians can adjust the size of the air outlet 52 as needed.

[0050] In this embodiment, the formula maker 100 also includes a cover plate 6, as shown in the reference. Figure 1 and Figure 3 The cover 6 covers the bottle basket 1111 and is located on top of the bottle holder 111. When the shaker 100's mixing and / or heating / keeping functions are needed, the cover 6 can be removed from the opening of the bottle basket 1111 and magnetically attached to the outer surface of the bottle maker 100's housing 1 above the bottle basket 1111 (e.g., magnetically attached to the surface of the upper housing 12 facing the user, or other locations) to prevent the cover 6 from being difficult to find due to carelessness. When the shaking and / or heating / keeping functions are not needed, the cover 6 covers the opening of the bottle basket 1111 to prevent dust from falling into the bottle basket 1111 and to support the bottles and other containers above it.

[0051] In this embodiment, the shaking mechanism 2 includes a motor 21, a driving wheel 22, and a driven wheel 23. (Reference) Figure 3 The motor 21 is located near the outer side of the bottle basket 1111. The bottom of the motor 21 has a downward protruding output shaft 211. The output shaft 211 is fitted with a motor bushing 212, a motor engagement silicone ring 213, and a drive wheel 22 in sequence. The drive wheel 22 is connected to the motor engagement silicone ring 213 of the motor 21, which can play the role of shock absorption, noise reduction, and extending the service life of the motor 21. The center of the drive wheel 22 coincides with the axial direction of the output shaft 211. When the motor 21 is powered on and started, the output shaft 211 drives the drive wheel 22 to rotate together. The driven wheel 23 is connected to the drive wheel 22 by a conveyor belt 24. The conveyor belt 24 is respectively fitted into the outer edge grooves of the drive wheel 22 and the driven wheel 23. The driven wheel 23 is located at the bottom of the bottle holder 111, specifically, below the bottle basket 1111. When the driven wheel 23 rotates, it can drive the bottle basket 1111 to rotate or shake together. In other embodiments, the shaking mechanism 2 may also adopt other mechanical transmission forms, which are not specifically limited here.

[0052] To make the shaking mechanism 2 more stable and reduce noise generation, in this embodiment, the shaking mechanism 2 further includes a positioning mounting member 25 and a bearing 26. (Refer to...) Figure 3 and Figure 8 One end of the positioning mounting component 25 is a driven wheel mounting cavity 231. To effectively reduce the radial and axial displacement of the components during the operation of the shaking mechanism 2, the positioning mounting component 25 includes an axial limiting plate 251 and a radial limiting plate 252, with the axial limiting plate 251 perpendicular to the radial limiting plate 252. The bearing 26 is annularly positioned above the driven wheel 23 to prevent hard friction between the driven wheel 23 and other components during rotation, thus improving transmission smoothness. The bearing 26 is located within the bearing mounting cavity 261 between the axial limiting plate 251 and the radial limiting plate 252. During the operation of the shaking mechanism 2, the bearing 26 is subjected not only to the radial limiting effect of the radial limiting plate 252 but also to the axial limiting effect of the axial limiting plate 251.

[0053] In this embodiment, the formula maker 100 includes a housing 1, a kettle 31, a pump 33, a solenoid valve 34, a water tank 9, and a water level detection mechanism 945. (Refer to...) Figure 2 and Figure 13 The housing 1 includes a base 11 and an upper housing 12. The front side of the base 11 is a bottle holder 111, and the rear side is a water bottle holder 112. The bottle holder 111 is used to hold a baby bottle (not shown in the figure). The bottom of the upper housing 12 is connected to the base 11. The connection between the upper housing 12 and the base 11 is located between the bottle holder 111 and the water bottle holder 112. The top of the upper housing 12 has a liquid outlet 32 ​​that is opposite to the bottle holder 111. The water bottle 31 is placed in the water bottle holder 112. The inlet of the pump 33 is connected to the bottom of the water bottle 31. The solenoid valve 34 is connected to the outlet of the pump 33. The solenoid valve 34 has a first outlet (not shown in the figure) and a second outlet (not shown in the figure). The first outlet is connected to the liquid outlet 32. The water tank 9 is installed on the top of the upper housing 12 and is connected to the second outlet. The water level detection mechanism 945 is set on the water tank 9 or the upper housing 12 to detect the water level in the water tank 9. In some embodiments, two pumps 33 may be provided. One pump 33 is connected to the kettle 31 and the outlet 32 ​​at both ends, and the other pump 33 is connected to the kettle 31 and the water tank 9 at both ends. The number of solenoid valves 34 may also be one or two. This embodiment does not limit this.

[0054] In this embodiment, the kettle base 112 has an upward-opening cylindrical second receiving cavity 113. The shape of the horizontal cross-section of the second receiving cavity 113 matches the shape of the horizontal cross-section of the bottom of the kettle 31. The user can directly place the kettle 31 stably in the second receiving cavity 113 of the kettle base 112, so that the water in the kettle 31 flows through the outlet 32 ​​to the bottle placed in the preset position of the bottle holder 111 below the outlet 32. The user can also directly lift the kettle 31 upward to separate it from the main body of the formula maker 100, and pour the water in the kettle 31 directly to other places where water is needed. The water in the kettle 31 will not leak from the bottom of the kettle 31 after separation. The electrical connection structure and water connection structure between the kettle 31 and the kettle base 112 can be made with reference to the prior art, and this embodiment does not limit them.

[0055] refer to Figure 1 and Figure 2 In this embodiment, the formula maker 100 has a first control panel 1A on the outer surface of its upper housing 12. When the water jug ​​31 is placed on the water jug ​​base 112, the user can touch the first control panel 1A to heat the water in the jug 31 to boiling point and then let it cool for later use. Alternatively, the water in the jug 31 can be selectively directed to the outlet 32 ​​or the water tank 9. Simultaneously, the user can also set the parameters on the first control panel 1A to specify the volume or flow time of the water flowing through the outlet 32 ​​and the water flowing to the water tank 9. The buttons on the surface of the first control panel 1A are oriented towards the side that facilitates the user placing the bottle into the bottle base 111.

[0056] In this embodiment, the pump 33 is disposed in the base 11 and located below the kettle seat 112. When the user places the kettle 31 stably in the second receiving cavity 113 of the kettle seat 112, the movable opening at the middle position of the bottom of the kettle 31 automatically connects with the water inlet of the pump 33. The user can start or stop the pump 33 through the first control panel 1A. When the pump 33 is started, water in the kettle 31 will be drawn into the pump 33 from the bottom of the kettle 31, and then discharged by the pump 33 to the outlet 32 ​​or the water tank 9.

[0057] In cases where the interval between two uses of the formula maker 100 is long, to prevent the formula maker 100 from continuing to discharge water remaining in its internal pipes after the previous use to the outlet 32, thus causing the temperature of the water flowing into the bottle to be lower than the preset temperature, this embodiment incorporates a water tank 9. Before each use of the formula maker 100 to dispense liquid through the outlet 32, the user can use the touch control panel 1A or the automatic residual water collection program built into the formula maker 100 to discharge the residual water remaining in its internal pipes after the previous use into the water tank 9 for temporary storage.

[0058] In this embodiment, once the water in the kettle 31 has cooled to a suitable temperature and the bottom of the kettle 31 is connected to the inlet of the pump 33, the pump 33 is started by the first control panel 1A. At this time, water will be drawn into the pump 33 from the bottom of the kettle 31, and then flow into the solenoid valve 34 through the outlet of the pump 33. The user can control the first outlet of the solenoid valve 34 to open and the second outlet to close by touching the first control panel 1A, so that the water flowing through the solenoid valve 34 flows directly to the liquid outlet 32 ​​for use in preparing milk powder or for direct drinking.

[0059] Alternatively, the user can touch the buttons on the surface of the first control panel 1A to open the second outlet of the solenoid valve 34 and close the first outlet, allowing water flowing into the solenoid valve 34 to flow into the water tank 9 through the second outlet. Simultaneously, by setting the volume of water flowing into the water tank 9 through the second outlet or the water inflow time, it is ensured that after the formula maker 100 is used, the water remaining in the pipes is completely drained into the water tank 9. After the residual water collection process in the water tank 9 is complete, the user can touch the buttons on the surface of the first control panel 1A to open the first outlet of the solenoid valve 34 and close the second outlet, switching the water flowing through the solenoid valve 34 to the liquid outlet 32. At this time, the water used for preparing formula or for direct drinking originates from the kettle 31. In other embodiments, the user can also adjust the first control panel 1A to enable the first and second outlets of the solenoid valve 34 to automatically switch modes. Each time the device is used, the second outlet of the solenoid valve 34 automatically opens first, allowing residual water in the internal pipes of the formula maker 100 after the last use, or some water from the kettle 31, to drain into the water tank 9. Subsequently, the solenoid valve 34 automatically switches to open the first outlet, allowing freshly boiled and cooled water from the kettle 31 to flow through the outlet 32 ​​to the bottle or other container. In the above embodiments, the opening time of the second outlet of the solenoid valve 34 can be designed according to the length of the internal pipes of the formula maker 100 and the drainage power of the pump 33, and is not specifically limited here.

[0060] refer to Figure 2 Above the liquid outlet 32, there is an upward-opening cylindrical mounting groove 95. The water tank 9 includes an upward-opening hollow cylindrical box body 91 and a lid 92 covering the opening above the box body 91. The horizontal cross-sectional shape of the mounting groove 95 matches the horizontal cross-sectional shape of the water tank 9, allowing the water tank 9 to be stably placed in the mounting groove 95. Furthermore, the height of the water tank 9 is higher than the side wall height of the mounting groove 95, allowing the user to hold the top of the water tank 9 and easily place or remove it from the mounting groove 95. According to the above embodiment, by integrating the water tank 9 into the top vertical region of the upper housing 12 of the formula maker 100, the overall horizontal footprint of the formula maker 100 can be reduced, making it suitable for various scenarios.

[0061] In this embodiment, a water inlet channel 93 is provided protruding inward at the center of the bottom of the housing 91 of the water tank 9, and the formula maker also includes a sealing assembly 94. (See reference) Figure 9 and Figure 10 The sealing assembly 94 includes a sealing plug 941 and a first sealing ring 942. The lower part of the sealing plug 941 is located inside the water inlet channel 93, and partially extends out of the top of the water inlet channel 93. The top of the sealing plug 941 extends out of the water inlet channel 93. The first sealing ring 942 is sleeved on the outer periphery of the top of the sealing plug 941. A spring 943 is sleeved on the outer periphery of the lower part of the sealing plug 941 inside the water inlet channel 93. The sealing plug 941 can be telescopically opened or closed by the spring 943. Specifically, the spring 943 is disposed inside the water inlet channel 93, and the deformation extension direction of the spring 943 is perpendicular to the bottom plane of the housing 91 of the water tank 9. One end of the spring 943 is fixedly connected to the top edge of the water inlet channel 93, and the other end is sleeved on the bottom outer periphery of the sealing plug 941, so that the spring 943 extends and retracts up and down in the water inlet channel 93 to drive the first sealing ring 942 and the sealing plug 941 to move up and down. When the sealing plug 941 moves upward, a water outlet gap is formed between the first sealing ring 942 and the top of the water inlet channel 93. When the sealing plug 941 moves downward, it abuts against the top of the water inlet channel 93 to seal the top opening of the water inlet channel 93.

[0062] When the water tank 9 is removed from the mounting slot 95, due to the elastic restoring force of the spring 943, the sealing plug 941 connected to one end of the spring 943 is subjected to the elastic restoring force of the spring 943 moving away from the water tank 9, so that the first sealing ring 942 seals the water inlet channel 93. At this time, the bottom of the box 91 is in a closed state, and liquid cannot enter the box 91 from the water inlet channel 93 at the bottom of the box 91 or flow out of the box 91. The user can pour out the remaining water from the top of the box 91 without worrying about the remaining water leaking out from the bottom.

[0063] refer to Figure 10 and Figure 11 The bottom center of the mounting groove 95 is provided with a pin 952 and a mounting groove outlet 951. The pin 952 is configured to be inserted into the sealing plug 941, so that the pin 952 applies an upward force to the spring 943, thereby connecting the mounting groove outlet 951 with the water inlet channel 93 and the water outlet gap.

[0064] Specifically, when the water tank 9 is completely returned to the mounting slot 95, part of the ejector pin 952 is inserted into the sealing plug 941. The spring 943 connected to the sealing plug 941 is indirectly subjected to the upward pressure of the ejector pin 952, causing the sealing plug 941 to move upward until the first sealing ring 942 separates from the water inlet channel 93. At this time, a water outlet gap is formed between the first sealing ring 942 and the top of the water inlet channel 93. The bottom of the water tank 9 can be connected to the water outlet 951 of the mounting slot through the water outlet gap and the water inlet channel 93. If the second water outlet of the pump 33 and the solenoid valve 34 is opened at this time, the water in the pipe of the formula maker 100 and the water bottle 31 can pass through the water outlet 951 of the mounting slot, the water inlet channel 93 and the water outlet gap in sequence to the water tank 9.

[0065] To ensure that the ejector pin 952 can smoothly lift the sealing plug 941, the bottom of the sealing plug 941 is provided with a groove 944, for reference. Figure 10 and Figure 11 The bottom of the sealing plug 941 has a hollow structure, and four ribs 9441 are distributed on the circumferential surface of the hollow structure. The four ribs 9441 enclose a groove 944 for the insertion of the ejector pin 952. When the ejector pin 952 enters the groove 944 formed by the four ribs 9441, the ejector pin 952 and the sealing plug 941 are engaged. When the water tank 9 is pressed down, the spring 943 is compressed upward under the reaction force of the ejector pin 952. The sealing plug 941 moves upward as the spring 943 is compressed. At this time, the ejector pin 952 can smoothly push the sealing plug 941 upward.

[0066] Furthermore, to prevent water from entering the installation groove 95 through the gap between the outlet 951 and the inlet channel 93 during the above residual water collection process, making it difficult to pour, in this embodiment, a second sealing ring 953 is also provided around the outer periphery of the outlet 951 of the installation groove. When the water tank 9 is placed in the preset position in the installation groove 95, the second sealing ring 953 fits against the outer periphery of the lower surface of the inlet channel 93 of the box body 91.

[0067] In this embodiment, the formula maker 100 also includes a touch switch 96, located on the top of the upper housing 12, to detect whether the water tank 9 is properly installed. (See reference) Figure 1 and Figure 2The touch switch 96 extends upward from the side wall of the mounting slot 95. The touch switch 96 is horizontally movable. When the water tank 9 is fully inserted into the mounting slot 95, the side wall of the water tank 9's housing 91 abuts against the touch switch 96, pushing the touch switch 96 into the upper housing 12 to a certain depth. If the water tank 9 is removed from the mounting slot 95 or fails to be properly installed within it, the touch switch 96 will extend from or be pushed into the upper housing 12 to a depth less than the preset value. The touch switch 96 will then detect that the water tank 9 is not properly installed and will prevent the pump 33 from starting, thus preventing water from directly entering the mounting slot 95 through the outlet 951, which could cause difficulty in emptying residual water or even allow residual water to enter other parts of the formula maker 100, causing a short circuit. In other embodiments, the formula maker 100 may also detect whether the water tank 9 is properly installed using other detection devices; no specific limitations are specified here.

[0068] In this embodiment, the housing 91 of the water tank 9 can be made of transparent plastic, allowing the user to directly observe the remaining water level in the tank 9 through the housing 91. However, in some high-frequency usage scenarios, the user may not be able to check the water level in the tank 9 in time, resulting in overflow of remaining water. Therefore, this embodiment provides a water level detection mechanism 945 at the water tank 9 or the upper housing 12 of the formula maker 100 to ensure that the user can remove the water tank 9 and empty the remaining water in time. To make the water level detection mechanism 945 more effective in indicating the water level in the tank 9, in this embodiment, the water level detection mechanism 945 includes a prompting unit. When the water level detection mechanism 945 detects that the water level is higher than a threshold, the prompting unit issues a prompt message. Specifically, the prompting unit is an indicator light, a buzzer, or a voice output module, allowing the user to promptly understand that the remaining water in the tank 9 needs to be emptied through sound or light effects. In this embodiment, the water level detection mechanism 945 is a capacitive water level detection mechanism 945. Since the water tank 9 in this embodiment is a cylindrical transparent box 91, multiple external water level plates of the capacitive water level detection mechanism 945 can be installed adjacent to the side wall of the mounting groove 95. The circuit capacitance value of the capacitive water level detection mechanism 945 changes with the water level in the water tank 9, and then the change in circuit capacitance value is sent to the prompting unit via an electrical signal. When the water level in the water tank 9 exceeds the threshold, the circuit capacitance value in the capacitive water level detection mechanism 945 reaches the preset value that triggers an alarm in the prompting unit, thereby achieving the purpose of the water level detection mechanism in this embodiment to remind users of changes in the water level in the water tank 9. In other embodiments, the water level detection mechanism 945 can also be other types of water level detection devices, or it can be connected to the formula maker 100 via a mobile phone or other smart device, so that users can more conveniently understand the water level in the water tank 9. No specific limitations are made here.
