Specific embodiments

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] This embodiment provides a milk warmer 100. Figure 1 It is a front view of the structure of a milk warmer 100 provided in this embodiment, Figure 2 It is a cross-sectional view of the structure of a milk warmer 100 provided in this embodiment, in combination with Figure 1 and Figure 2As shown in the figure, the milk powder mixer 100 includes a milk bottle holder 111, a shaking mechanism 2, a liquid discharging mechanism 3, and a heater 4. Among them, the milk bottle holder 111 is used to place and fix a milk bottle (not shown in the figure); the shaking mechanism 2 is connected to the milk bottle holder 111 and drives the milk bottle to shake via the milk bottle holder 111; the liquid discharging mechanism 3 has a liquid discharging port 32 correspondingly arranged above the milk bottle holder 111, and the liquid discharging mechanism 3 is configured to supply liquid into the milk bottle via the liquid discharging port 32; the heater 4 is configured to heat the milk bottle in the milk bottle holder 111.

[0040] In this embodiment, by integrating components such as the milk bottle holder 111, the shaking mechanism 2, the liquid discharging mechanism 3, and the heater 4 into the milk powder mixer 100, the milk powder mixer 100 simultaneously has functions of liquid discharging for brewing, shaking, and heating and keeping warm. Among them, according to actual usage needs, the user can perform personalized settings on the operating state and operating time of the milk powder mixer 100 provided in this embodiment, and can independently control the liquid discharging for brewing, shaking, and heating and keeping warm functions of the milk powder mixer 100 respectively, or can freely combine the above three functions to make them operate in coordination with each other.

[0041] Refer to Figure 1 and Figure 2 , above the outer surface of the housing 1 of the milk powder mixer 100 in this embodiment, there is a first control panel 1A for controlling the liquid discharging mechanism 3; below the outer surface of the housing 1 of the milk powder mixer 100, there is a second control panel 1B for controlling the shaking mechanism 2, the heater 4, and other components for heating and keeping warm. The keys / touchscreens provided on the surfaces of the first control panel 1A and the second control panel 1B all face the side convenient for the user to place the milk bottle, improving the convenience of operation.

[0042] Taking some usage situations where infants and young children need to be fed with milk powder as an example, after the user places the milk bottle at the preset position in the milk bottle holder 111 of the milk powder mixer 100 and completes the fixation, the user can set the liquid discharging parameters by adjusting the keys provided on the surface of the first control panel 1A, so that the liquid discharging mechanism 3 adds a preset volume of water into the milk bottle directly below it. After the above liquid discharging process is completed, the user first adds an appropriate amount of milk powder into the milk bottle and installs the supporting milk bottle cap at the opening of the milk bottle to prevent the milk liquid from spilling onto the surface and inside of the milk powder mixer 100 during subsequent operations, causing equipment damage or the site to be messy. Subsequently, the shaking mechanism 2 of the milk powder mixer 100 can be automatically started, or can be started by manually controlling the keys / touchscreen of the second control panel 1B to make the milk bottle in the milk bottle holder 111 rotate or shake mechanically. Among them, the frequency and amplitude of rotation or shaking can be set by the user pressing the second control panel 1B to set the shaking parameters. Compared with manual shaking, the shaking function of the milk powder mixer 100 provided in this embodiment can make the shaking process more uniform and efficient, ensuring that the milk powder in the milk bottle is fully dissolved.

[0043] The heater 4 in this embodiment can heat the milk bottle in the bottle holder 111, that is, perform heating and insulation operations on the milk liquid. When the temperature of the water supplied to the milk bottle by the liquid discharging mechanism 3 is too low or the temperature of the milk liquid drops below the temperature range suitable for infants and young children during the shaking process, the heater 4 can be automatically started or can also be started manually by operating the second control panel 1B. The heating and insulation components such as the heater 4 in the above heating and insulation process can operate independently or can also operate simultaneously with the shaking mechanism 2. Through the above embodiment, after the shaking process of the milk mixer 100 is completed, the temperature of the milk bottle and the milk liquid always remains within the temperature range suitable for infants and young children. At this time, when the user removes the milk bottle from the bottle holder 111, the user can directly feed the infants and young children. In addition, for the case where the whole bottle of milk is not fed at one time, the user can also place the milk bottle containing the remaining milk liquid in the bottle holder 111, and then restart the shaking mechanism 2 and the heater 4 to heat the remaining milk liquid to the temperature range suitable for infants and young children again and perform insulation.

[0044] The milk mixer 100 provided in this embodiment not only has the functions of milk mixing, shaking, heating and insulation at the same time, which can meet the diverse needs of users; its integrated design makes the overall structure of the milk mixer 100 compact, reduces its occupied space, and can meet the requirements in different usage scenarios. To enable the water discharged from the liquid discharging mechanism 3 to accurately and smoothly fall into the milk bottle placed in the bottle holder 111, and to ensure that the milk bottle can always be kept in the preset position of the bottle holder 111 when the shaking, heating and insulation functions of the milk mixer 100 are operating. In this embodiment, the bottle holder 111 includes a bottle basket 1111 and a plurality of elastic pieces 1115. Refer to Figure 2 and Figure 3, the milk bottle basket 1111 has a first accommodating cavity 1112 for accommodating a milk bottle. The center position of the opening of the first accommodating cavity 1112 is directly opposite to the liquid outlet 32 above it. One end of the elastic piece 1115 is connected to the peripheral edge of the top of the milk bottle basket 1111, and the other end extends radially inward. The milk bottle is configured to be inserted into the area enclosed by the central enclosure of a plurality of elastic pieces 1115 and is clamped and fixed by the plurality of elastic pieces 1115. The elastic piece 1115 is made of a plastic or metal material that can undergo elastic deformation. When the milk bottle has not been inserted into the first accommodating cavity 1112 of the milk bottle basket 1111, the cross-sectional area enclosed by the end of the elastic piece 1115 extending inward is smaller than the horizontal cross-sectional area of the milk bottle when it is placed vertically. When the milk bottle is inserted into the first accommodating cavity 1112 of the milk bottle basket 1111, the ends of the plurality of elastic pieces 1115 extending inward are squeezed by the milk bottle and approach the bottom and side walls of the first accommodating cavity 1112. As a result, the elastic piece 1115 generates elastic potential energy toward the center position of the first accommodating cavity 1112. By applying horizontal forces in opposite directions and of the same magnitude to the milk bottle through the plurality of elastic pieces 1115, the milk bottle can be firmly clamped at the center position of the first accommodating cavity 1112 of the milk bottle basket 1111, and it is ensured that the water flowing out through the liquid outlet 32 can fall vertically into the milk bottle. Preferably, the milk bottle seat 111 has four elastic pieces 1115 evenly distributed along the peripheral edge of the top of the milk bottle basket 1111. Of course, the number of elastic pieces 1115 is not limited to 4. To prevent the end of the elastic piece 1115 extending inward from scratching the outer surface of the milk bottle when the milk bottle is inserted into the milk bottle basket 1111 and to make the process of inserting the milk bottle into the milk bottle basket 1111 smoother, in this embodiment, the end of the elastic piece 1115 connected to the peripheral edge of the top of the milk bottle basket 1111 is higher than its end extending inward, so that the elastic piece 1115 forms an inclined guiding surface for guiding the milk bottle to be inserted downward. Moreover, the end of the elastic piece 1115 extending inward is provided with an edge portion 11151 that extends smoothly downward. The outer shape of the surface of the edge portion 11151 is arc-shaped to be used for fitting the outer surface of the milk bottle, increasing the contact area with the milk bottle surface and improving the installation stability of the milk bottle.

[0045] Since the milk warmer 100 provided in this embodiment itself has a heating and insulation function, the elastic pieces 1115 in the milk bottle basket 1111 may be prone to material aging due to being in a relatively high-temperature environment for a long time, resulting in a decrease in the clamping performance of the elastic pieces 1115 for the milk bottle. As a result, the clamping position of the milk bottle during the shaking process may change or the milk bottle may be directly thrown out of the milk bottle basket 1111. To address this, the milk warmer 100 of this embodiment is also provided with a double torsion spring 1116. Refer to Figure 3 and Figure 4 , the elastic piece 1115 and the peripheral edge of the top of the milk bottle basket 1111 are connected by the double torsion spring 1116. Specifically, refer to Figure 4 and Figure 5, the 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 arranged on both sides of the torsion frame 11164. Torsion bars 11163 are arranged on the sides of the first torsion spring 11161 and the second torsion spring 11162 far away from the torsion frame 11164. The torsion frame 11164 is engaged in a torsion spring mounting member 1114 arranged above the side wall of the milk bottle basket 1111. In this embodiment, the two torsion bars 11163 respectively abut against the two side edges of the lower surface of the elastic piece 1115. When the milk bottle is inserted into the milk bottle basket 1111, the depressed elastic piece 1115 pushes the torsion bar 11163 downward, and causes a torsional deformation between the first torsion spring 11161 and the second torsion spring 11162 and the torsion frame 11164, thereby converting the external force applied by the milk bottle into elastic potential energy. During the insertion process of the above milk bottle, the double torsion spring 1116 and the elastic piece 1115 jointly apply an elastic force to the milk bottle, so as to firmly clamp the milk bottle in the milk bottle basket 1111. Even if the elastic piece 1115 ages, the double torsion spring 1116 still has good elastic reset ability and continuously pushes the elastic piece 1115 to clamp the milk bottle. Compared with a single torsion spring, the double torsion spring 1116 has a higher load capacity and a stronger torque output, improving the service life of the elastic piece 1115; preferably, refer to Figure 2 and Figure 12 , a milk bottle clamping sleeve 111SA is clamped on the top of the milk bottle seat 11. The inner ring of the milk bottle clamping sleeve 1115A further includes a plurality of elastic 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 milk bottle clamping sleeve 1115A, and the torsion bar 11163 abuts against the lower surface of the elastic piece ll15. To achieve the function of heating and heat preservation, in this embodiment, the side wall of the milk bottle basket 1111 has grid holes 1113, and the milk warmer 100 further includes a blower 5. Refer to Figure 2 and Figure 3 , the hot air formed by the heater 4 is blown into the milk bottle basket 1111 through the grid holes 1113 by using the blower 5 to heat the milk bottle. To make the heating and heat preservation process of the milk warmer 100 more efficient and the temperature of the milk liquid more uniform, the cross-sectional shape of the grid holes 1113 in this embodiment is rectangular, located at the bottom of the side wall of the milk bottle basket 1111, and is arranged in a ring shape evenly. In other embodiments, the cross-sectional shape and size of the grid holes 1113 are not specifically limited.

[0046] In this embodiment, the liquid outlet mechanism 3 includes a water kettle 31, a liquid outlet pipeline (not shown in the figure), and a hot water mechanism. Among them, the hot water mechanism heats the water in the water kettle 31, and the liquid outlet pipeline communicates the water kettle 31 and the liquid outlet 32. Specifically, after the water in the water kettle 31 is heated to boiling, it can be temporarily stored in the water kettle 31 for cooling and standby. More preferably, when the water in the water kettle 31 cools to 40°C - 50°C after boiling, the water in the water kettle 31 is added to the milk bottle through the liquid outlet mechanism 3. Using water at the above temperature to prepare milk powder can, on the one hand, avoid the inactivation of active ingredients in the milk powder at high temperatures; on the other hand, it is conducive to the milk powder being dissolved more quickly and evenly. In addition, since the optimal temperature of the milk liquid suitable for infants and young children to drink is 45°C, by using the above drinking water cooled to 40°C - 50°C to prepare milk powder, the temperature of the milk liquid can reach the optimal drinking temperature of infants and young children more quickly.

[0047] To enable users to clearly understand the real-time temperature of the milk liquid, in this embodiment, a temperature detection element 7 is also provided in the milk bottle holder 111 to detect the temperature of the milk bottle. Refer to Figure 3 and Figure 6 , the temperature detection element 7 is arranged at the center position of the bottom of the milk bottle basket 1111. When the milk bottle is completely inserted into the milk bottle basket 1111 and firmly clamped, by measuring the temperature of the bottom of the milk bottle through the temperature detection element 7, users can accurately understand whether the milk liquid has reached the preset temperature. More preferably, the temperature detection element 7 is an infrared sensor. In other embodiments, the temperature detection element 7 can also be selected from other temperature sensing devices, which are not specifically limited here. Refer to Figure 6 , surrounding the temperature detection element 7, there is also an O-ring 8 and a support structure 81. By closely fitting the O-ring 8 with the support structure 81, hot air and water can be prevented from entering the position where the temperature detection element 7 is located, improving the accuracy of temperature detection.

[0048] To improve the heating and heat preservation efficiency, and at the same time make full use of the internal space of the milk warmer 100 to realize the miniaturization of the milk warmer 100, in this embodiment, as Figure 2 shown, the blower 5 is arranged at the bottom of the upper housing 12, and a first air duct 5A is formed from the connection between the upper housing 12 and the base 11 to the milk bottle holder 111, and the heater 4 is arranged in the first air duct 5A. The air inlet 51 of the blower 5 is arranged at a position adjacent to or corresponding to the water kettle 31, and an air inlet hole is correspondingly opened at the position of the upper housing 12 corresponding to the air inlet of the blower 5. When there is hot water in the water kettle 31, the air around the water kettle 31 is heated. Refer to Figure 2 and Figure 3 , as the heating and heat preservation function of the milk warmer 100 is activated, the hot air around the water kettle 31 is sucked into the first air duct 5A through the air inlet 51, and after being reheated by the heater 4, the warm air heats and preserves the milk bottle in the milk bottle basket 1111 through the grille holes 1113.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 outer periphery of the baby bottle basket 1111. The warm air input by the blower 5 and heated by the heater 4 enters the second air duct 5B between the outer shell 1117 of the baby bottle basket 1111 and the grille holes 1113 through the air outlet 52, and then passes through the grille holes 1113 from the second air duct 5B to heat the baby bottles in the baby bottle basket 1111. In this embodiment, the relatively large air outlet 52 can ensure that after the warm air enters the second air duct 5B of the baby bottle basket 1111, it is split into two or three airflows, which flow circumferentially around the baby bottle basket 1111 towards the left and right sides in the horizontal direction of the air outlet 52, or can also overflow from above the second air duct 5B. Technicians can adjust the size of the air outlet 52 as needed.

[0049] In this embodiment, the milk warmer 100 further includes a cover plate 6. Refer to Figure 1 and Figure 3 , the cover plate 6 covers the baby bottle basket 1111 and is arranged on the top of the baby bottle base 111. When the shaking and / or heating and keeping warm functions of the milk warmer 100 are needed, the cover plate 6 can be removed from the opening of the baby bottle basket 1111 and magnetically positioned on the outer surface of the housing 1 of the milk warmer 100 above the baby bottle basket 1111 (for example, magnetically positioned on the surface of the upper housing 12 facing the user, or other positions) to prevent the cover plate 6 from being difficult to find due to being discarded randomly; when the shaking and / or heating and keeping warm functions are not needed, the cover plate 6 covers the opening of the baby bottle basket 1111, which can prevent dust from falling into the baby bottle basket 1111 and support containers such as baby bottles above it.

[0050] In this embodiment, the shaking mechanism 2 includes a motor 21, a driving wheel 22 and a driven wheel 23. Refer to Figure 3 , the motor 21 is arranged adjacent to the outer side of the baby bottle basket 1111. A downwardly protruding output shaft 211 is provided at the bottom of the motor 21. An outer motor shaft sleeve 212, a motor meshing silica gel ring 213 and a driving wheel 22 are sequentially sleeved outside the output shaft 211. The driving wheel 22 is connected to the motor meshing silica gel ring 213 of the motor 21, which can play a role in shock absorption, noise reduction and extending the service life of the motor 21. The center of the driving 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 driving wheel 22 to rotate together; the driven wheel 23 is connected to the driving wheel 22 by a conveyor belt 24. The conveyor belt 24 is respectively sleeved in the outer edge grooves of the driving wheel 22 and the driven wheel 23; the driven wheel 23 is arranged at the bottom of the baby bottle base 111. Specifically, the driven wheel 23 is arranged below the baby bottle basket 1111. When the driven wheel 23 rotates, it can drive the baby bottle basket 1111 to rotate or shake together. In other embodiments, the shaking mechanism 2 can also adopt other mechanical transmission forms, which are not specifically limited herein.

[0051] To make the structure of the shaking mechanism 2 more stable and reduce noise generation, in this embodiment, the shaking mechanism 2 further includes a positioning and mounting member 25 and a bearing 26. Among them, referring to Figure 3 and Figure 8 , one end of the positioning and mounting member 25 is a driven wheel mounting cavity 231. To effectively reduce the radial and axial displacements of the components during the operation of the shaking mechanism 2, the positioning and mounting member 25 includes an axial limiting plate 251 and a radial limiting plate 252, and the axial limiting plate 251 is perpendicular to the radial limiting plate 252. The bearing 26 is disposed around the driven wheel 23, which can prevent hard abrasion between the driven wheel 23 and other components during rotation and improve the transmission smoothness. The bearing 26 is disposed in a 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 not only radially limited by the radial limiting plate 252 but also axially limited by the axial limiting plate 251.

[0052] In this embodiment, the milk warmer 100 includes a housing 1, a water kettle 31, a pump 33, a solenoid valve 34, a water tank 9, and a water level detection mechanism 945. Among them, referring to ​ and ​ , the housing 1 includes a base 11 and an upper housing 12. The front side of the base 11 is a baby bottle holder 111, and the rear side is a water kettle holder 112. The baby bottle holder 111 is used to place a baby bottle (not shown in the figure). The bottom of the upper housing 12 is connected to the base 11, and the connection between the upper housing 12 and the base 11 is located between the baby bottle holder 111 and the water kettle holder 112. The top of the upper housing 12 has a liquid outlet 32 disposed opposite to the baby bottle holder 111; the water kettle 31 is placed in the water kettle holder 112; the water inlet of the pump 33 is communicated with the bottom of the water kettle 31; the solenoid valve 34 is connected to the water outlet of the pump 33. The solenoid valve 34 has a first water outlet (not shown in the figure) and a second water outlet (not shown in the figure). The first water outlet is connected to the liquid outlet 32; the water tank 9 is installed on the top of the upper housing 12, and the water tank 9 is communicated with the second water outlet; the water level detection mechanism 945 is disposed in 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 can also be provided. One pump 33 is respectively communicated with the water kettle 31 and the liquid outlet 32 at both ends, and the other pump 33 is respectively communicated with the water kettle 31 and the water tank 9 at both ends. The number of solenoid valves 34 can also be one or two, and this embodiment does not limit this.

[0053] In this embodiment, the kettle base 112 has a cylindrical second accommodation cavity 113 with an upward opening. The shape of the horizontal cross-section of the second accommodation 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 accommodation cavity 113 of the kettle base 112, so that the water in the kettle 31 flows through the liquid outlet 32 into the feeding bottle placed in the preset position of the feeding bottle base 111 below the liquid outlet 32. The user can also directly lift the kettle 31 upward to separate it from the main body of the milk warmer 100, and directly pour the water in the kettle 31 to other places where water is needed. Moreover, the water in the separated kettle 31 will not leak from the bottom of the kettle 31. The electrical connection structure and the water connection structure between the kettle 31 and the kettle base 112 can refer to the prior art, and this embodiment does not limit this.

[0054] Reference ​ and ​ , above the outer surface of the upper shell 12 of the milk warmer 100 in this embodiment, there is a first control panel 1A. When the kettle 31 filled with water is placed on the kettle base 112, the user can heat the water in the kettle 31 to boiling and then let it cool for standby by touching the first control panel 1A, or the water in the kettle 31 can be selectively made to flow to the liquid outlet 32 or the water tank 9. At the same time, the user can also set parameters through the first control panel 1A to specify the volume or outflow time of the water flowing out through the liquid outlet 32 and the water flowing into the water tank 9. The keys on the surface of the first control panel 1A are oriented towards the side where it is convenient for the user to place the feeding bottle into the feeding bottle base 111.

[0055] In this embodiment, the pump 33 is arranged in the base 11 and is located below the kettle base 112. When the user places the kettle 31 stably in the second accommodation cavity 113 of the kettle base 112, the movable opening arranged at the middle position of the bottom of the kettle 31 is automatically connected to the water inlet of the pump 33, and the user can start or stop the pump 33 through the first control panel 1A. After the pump 33 is started, the water in the kettle 31 will be sucked from the bottom of the kettle 31 into the pump 33, and then discharged by the pump 33 to the liquid outlet 32 or the water tank 9.

[0056] In the case where the interval time between two uses of the milk warmer 100 by the user is relatively long, to prevent the milk warmer 100 from continuing to discharge the water remaining in the internal pipeline of the milk warmer 100 after the previous liquid discharge to the liquid outlet 32, resulting in the temperature of the water flowing into the feeding bottle being lower than the preset temperature. In this embodiment, by adding the water tank 9, before each use of the milk warmer 100 to discharge liquid through the liquid outlet 32, the user can discharge the remaining water in its internal pipeline to the water tank 9 for temporary storage by touching the first control panel 1A or through the automatic residual water collection program of the milk warmer 100 itself.

[0057] In this embodiment, when the water in the kettle 31 has cooled to an appropriate temperature and the bottom of the kettle 31 is already connected to the water inlet of the pump 33, the pump 33 is started by the first control panel 1A. At this time, the water is sucked from the bottom of the kettle 31 into the pump 33 and then flows into the solenoid valve 34 through the water outlet of the pump 33. The user can control the opening of the first water outlet and the closing of the second water outlet of the solenoid valve 34 by touching the first control panel 1A, so that the water passing through the solenoid valve 34 directly flows to the liquid outlet 32 for milk powder brewing or direct drinking.

[0058] Alternatively, the user can also touch the button on the surface of the first control panel 1A to first open the second water outlet and close the first water outlet of the solenoid valve 34, so that the water flowing into the solenoid valve 34 flows into the water tank 9 through the second water outlet. At the same time, by setting the volume of the water flowing into the water tank 9 through the second water outlet or the water inlet duration, it is ensured that after the last use of the milk warmer 100, the water remaining in the pipeline is more completely drained into the water tank 9. After the process of collecting the remaining water in the water tank 9 is completed, the user touches the button on the surface of the first control panel 1A to open the first water outlet and close the second water outlet of the solenoid valve 34, so that the water passing through the solenoid valve 34 is switched to flow to the liquid outlet 32. At this time, the water for brewing milk powder or direct drinking comes from the kettle 31. In other embodiments, the user can also adjust the first control panel 1A to make the first water outlet and the second water outlet of the solenoid valve 34 adopt an automatic switching mode. During each use, the second water outlet of the solenoid valve 34 is automatically opened first, so that the water remaining in the internal pipeline of the milk warmer 100 after the last use or part of the water from the kettle 31 is drained into the water tank 9; then the solenoid valve 34 is automatically switched to open the first water outlet, so that the newly boiled and cooled water from the kettle 31 flows through the liquid outlet 32 to the feeding bottle or other containers. In the above embodiments, the opening time of the second water outlet of the solenoid valve 34 can be designed according to the length of the pipeline inside the milk warmer 100 and the drainage power of the pump 33, and no specific limitation is made here.

[0059] Reference ​ , a cylindrical mounting groove 95 with an upward opening is provided above the liquid outlet 32. The water tank 9 includes a hollow cylindrical box body 91 with an upward opening and a box cover 92 covering the upper opening of 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, so that the water tank 9 can be stably placed in the mounting groove 95. And the height of the water tank 9 is higher than the height of the side wall of the mounting groove 95. The user can hold the upper part of the water tank 9 and more conveniently place the water tank 9 into the mounting groove 95 or take it out of the mounting groove 95. According to the above embodiments, by integrally designing the water tank 9 in the vertical area at the top of the upper housing 12 of the milk warmer 100, the overall horizontal floor area of the milk warmer 100 can be reduced, enabling it to be applicable in a variety of scenarios.

[0060] In this embodiment, an inlet passage 93 is provided in a convex manner in the middle of the bottom of the box body 91 of the water tank 9. The milk warmer further includes a sealing assembly 94. Refer to ​ and ​ , 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 in the inlet passage 93, and part of it extends out of the top of the inlet passage 93. The top of the sealing plug 941 extends out of the inlet passage 93. A 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 located in the inlet passage 93. The sealing plug 941 can open or close the inlet passage 93 in a telescopic manner by using the spring 943. Specifically, the spring 943 is arranged in the inlet passage 93, and the deformation extension direction of the spring 943 is perpendicular to the bottom plane of the box body 91 of the water tank 9. One end of the spring 943 is fixedly connected to the top edge of the inlet passage 93, and the other end is sleeved on the outer periphery of the bottom of the sealing plug 941, so that the spring 943 can telescopically move up and down in the inlet passage 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 inlet passage 93. When the sealing plug 941 moves downward, it abuts against the top of the inlet passage 93 to seal the top opening of the inlet passage 93.

[0061] When the water tank 9 is in a state of being taken out from the installation groove 95, due to the elastic restoring force of the spring 943 itself, the sealing plug 941 connected to one end of the spring 943 is subjected to the elastic restoring force of the spring 943 away from the water tank 9, so that the first sealing ring 942 closes the inlet passage 93. At this time, the bottom of the box body 91 is in a closed state, and the liquid cannot enter or flow out of the box body 91 from the inlet passage 93 at the bottom of the box body 91. The user can pour the remaining water from above the box body 91 without worrying about the remaining water leaking from the bottom.

[0062] Refer to ​ and ​ , a thimble 952 and an installation groove water outlet 951 are provided at the middle position of the bottom in the installation groove 95. The thimble 952 is configured to be inserted and connected with the sealing plug 941, so as to apply an upward acting force to the spring 943 through the thimble 952, and connect the installation groove water outlet 9t1 with the inlet passage 93 and the water outlet gap.

[0063] Specifically, when the water tank 9 is completely reinstalled into the installation groove 95, part of the ejector pin 952 is inserted into the sealing plug 941, and the spring 943 connected to the sealing plug 941 indirectly receives an upward pressure from the ejector pin 952, causing the sealing plug 941 to move upward until the first sealing ring 942 is separated from the water inlet channel 93. At this time, a water outlet gap is formed between the top of the first sealing ring 942 and the water inlet channel 93. The bottom of the water tank 9 can communicate with the installation groove water outlet 951 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 pipeline of the milk warmer 100 and the water kettle 31 can successively pass through the installation groove water outlet 951, the water inlet channel 93 and the water outlet gap and lead to the water tank 9.

[0064] To ensure that the ejector pin 952 can smoothly lift the sealing plug 941, a clamping groove 944 is provided at the bottom of the sealing plug 941. Refer to ​ and ​ , the bottom of the sealing plug 941 has a hollow structure, and four ribs 9441 are distributed at intervals on the circumferential surface of the hollow structure. The four ribs 9441 enclose to form a clamping groove 944 for the ejector pin 952 to insert. When the ejector pin 952 enters the clamping groove 944 formed by the four ribs 9441, the ejector pin 952 and the sealing plug 941 are engaged. Press the water tank 9 downward, and 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 lift the sealing plug 941 upward.

[0065] Furthermore, to prevent water from entering the installation groove 95 through the gap between the installation groove water outlet 951 and the water inlet channel 93 during the above-mentioned surplus water collection process, which is difficult to pour out, in this embodiment, a second sealing ring 953 is further provided around the outer periphery of the installation groove water outlet 951. When the water tank 9 is placed at a preset position in the installation groove 95, the second sealing ring 953 fits against the outer periphery of the lower surface of the water inlet channel 93 of the box body 91.

[0066] In this embodiment, the milk warmer 100 further includes a touch switch 96, which is arranged at the top of the upper shell 12 to detect whether the water tank 9 is installed in place. Refer to ​ and ​, the touch switch 96 is provided on the upwardly extending part of the side wall of the installation groove 95. The touch switch 96 can move horizontally. When the water tank 9 is completely placed into the installation groove 95, the side wall of the box body 91 of the water tank 9 abuts against the touch switch 96 and pushes the touch switch 96 into the inner part of the upper shell 12 to a certain depth. When the water tank 9 is removed from the installation groove 95 or fails to be installed in place in the installation groove 95, the touch switch 96 extends out of the inner part of the upper shell 12 or the depth pushed into the inner part of the upper shell 12 fails to reach the preset value. Then, the touch switch 96 detects that the water tank 9 is not installed in place and prohibits the pump 33 from starting, avoiding water directly entering the installation groove 95 through the installation groove water outlet 951, causing difficulty in pouring out the remaining water, and even the remaining water entering other parts of the milk warmer 100, resulting in a short circuit of the equipment circuit. In other embodiments, the milk warmer 100 can also detect whether the water tank 9 is installed in place through other detection devices, and no specific limitation is made here.

[0067] In this embodiment, the box body 91 of the water tank 9 can be made of transparent plastic, and the user can directly observe the water level of the remaining water collected in the water tank 9 through the box body 91. However, in some high-frequency usage scenarios, the user may not be able to check the water level of the water tank 9 in time, resulting in the overflow of the remaining water. Therefore, in this embodiment, a water level detection mechanism 945 is provided at the water tank 9 or the upper shell 12 of the milk warmer 100 to ensure that the user can take out the water tank 9 and pour out the remaining water in time. To make the prompt effect of the water level detection mechanism 945 on the water level in the water tank 9 more obvious, in this embodiment, the water level detection mechanism 945 includes a prompt part. When the water level detection mechanism 945 detects that the water level is higher than the threshold value, the prompt part emits a prompt message. Specifically, the prompt part is an indicator light, a buzzer or a voice output module, and the user can timely know that the remaining water in the water tank 9 needs to be poured out through the sound or light effect. 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 body 91, a plurality of external water level plates of the capacitive water level detection mechanism 945 can be arranged adjacent to the side wall of the installation groove 95. The circuit capacitance value of the capacitive water level detection mechanism 945 changes with the change of the water level in the water tank 9. Subsequently, the change value of the circuit capacitance value will be sent to the prompt part through an electric signal. As the water level in the water tank 9 is higher than the threshold value, the circuit capacitance value in the capacitive water level detection mechanism 945 reaches the preset value that triggers the alarm of the prompt part, thereby achieving the purpose that the water level detection mechanism can remind the change of the water level in the water tank 9 in this embodiment. In other embodiments, the water level detection mechanism 945 can also select other types of water level detection devices, and can also be signal-connected to the milk warmer 100 through a mobile phone or other intelligent devices, so that the user can more conveniently understand the water level in the water tank 9, and no specific limitation is made here.

[0068] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
