Technical Field

[0001] This disclosure relates to the field of home appliance technology, and in particular to a housing assembly and a milk preparation device. Background Technology

[0002] As living standards improve, people have higher and higher demands for maternal and infant products.

Among them, multi-functional bottle warmers integrate functions such as formula preparation, warming, sterilization, drying, and storage, allowing users to perform these operations without needing multiple devices, providing great convenience and making them very popular.

[0003] In related technologies, formula preparation equipment requires multiple cavities to achieve different functions and necessitates corresponding functional components. This results in a large volume of the formula preparation equipment's housing components, hindering its miniaturization. Utility Model Content

[0004] This disclosure provides a housing assembly and a formula preparation device. The housing assembly utilizes a ventilation chamber to supply gas to the insulation and sterilization chambers, and its compact structure facilitates size reduction. When used in conjunction with a warm air generating assembly, the housing assembly provides drying and insulation functions for the formula preparation device, further contributing to its miniaturization.

[0005] The technical solution is as follows:

[0006] According to a first aspect of the present disclosure, a housing assembly is provided, including a first housing, a first air duct, a second housing, and a second air duct. The first housing has a ventilation cavity and a heat insulation cavity separated from the ventilation cavity. The first air duct connects the ventilation cavity and the heat insulation cavity. The second housing is fixedly connected to the first housing, and the second housing has a disinfection cavity. The second air duct connects the ventilation cavity and the disinfection cavity.

[0007] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0008] When this housing assembly is used in a formula preparation device, the warm air generating component is connected to the ventilation chamber. At this time, the ventilation chamber is connected to the heat preservation chamber via a first air duct, and the ventilation chamber is connected to the sterilization chamber via a second air duct. This facilitates the delivery of warm air generated by the warm air generating component through the ventilation chamber into the heat preservation chamber for heat preservation or heating, and / or into the sterilization chamber for drying the bottles. In this way, the housing assembly can utilize the ventilation chamber to supply gas to the heat preservation and sterilization chambers, eliminating the need for integrated water heating components and making the housing assembly more compact, thus reducing its overall size.

[0009] The technical solution of this disclosure will be further explained below:

[0010] In one embodiment, the housing assembly further includes a switching valve assembly disposed in at least one of the first housing, the first air duct, the second housing, and the second air duct, such that the ventilation chamber is in communication with the insulation chamber and / or the disinfection chamber via the switching valve assembly. When the switching valve assembly is in a first switching state, the ventilation chamber is in communication with the insulation chamber but isolated from the disinfection chamber. When the switching valve assembly is in a second switching state, the ventilation chamber is in communication with the disinfection chamber but isolated from the insulation chamber.

[0011] In one embodiment, when the switching valve assembly is in the third switching state, the ventilation chamber is connected to the insulation chamber and the disinfection chamber;

[0012] And / or, the switching valve assembly includes a first switching valve disposed on a first air duct and a second switching valve disposed on a second air duct. When the switching valve assembly is in a first switching state, the first switching valve is open and the second switching valve is closed. When the switching valve assembly is in a second switching state, the first switching valve is open and the second switching valve is closed.

[0013] In one embodiment, the switching valve assembly includes a three-way valve. The three-way valve includes a valve seat and a valve movably disposed on the valve seat. The valve seat includes a first air outlet communicating with a first air duct, a second air outlet communicating with a second air duct, and an air inlet communicating with a ventilation cavity. When the three-way valve is in a first switching state, the valve is in a first state, such that the first air outlet is connected to the air inlet, while the second air outlet is disconnected from the air inlet. When the three-way valve is in a second switching state, the valve is in a second state, such that the first air outlet is disconnected from the air inlet, while the second air outlet is connected to the air inlet.

[0014] In one embodiment, the valve is rotatably mounted on a valve seat, and the valve includes an arc-shaped guide surface. When the valve is in a first state, the valve closes the second air outlet and directs airflow to the first air outlet through the arc-shaped guide surface. When the valve is in a second state, the valve closes the first air outlet and directs airflow to the second air outlet through the arc-shaped guide surface.

[0015] In one embodiment, the housing assembly further includes a cavity fixedly connected to the first housing. The cavity communicates with the insulation cavity. The cavity is inserted into the ventilation cavity and divides at least a portion of the ventilation cavity into annular flow channels. The annular flow channels communicate with a first air duct and a second air duct, respectively.

[0016] In one embodiment, the first housing includes an air inlet for connecting a warm air generating assembly. One end of an annular airflow channel communicates with the air inlet, and the other end communicates with a first air duct and a second air duct.

[0017] In one embodiment, the cavity and the bottom of the ventilation cavity are spaced apart.

[0018] In one embodiment, the cavity includes a cavity body and a support body. The cavity body is fixedly connected to a first housing, and the cavity body has a through cavity communicating with the insulation cavity. The support body covers the bottom of the through cavity. At least one of the support body and the cavity body has a third air vent, and the support body is slidably connected to at least one of the first housing and / or the cavity body, and has a load-bearing state with the third air vent open and a non-load-bearing state with the third air vent closed.

[0019] In one embodiment, the carrier can be reset to a non-loaded state.

[0020] In one embodiment, the housing assembly further includes a reset member. The reset member is disposed between the carrier and the first housing to allow the carrier to be reset to a non-load-bearing state. When the carrier is in a load-bearing state, the third vent is opened to allow the insulation cavity to communicate with the ventilation cavity through the third vent.

[0021] In one embodiment, the support body includes a load-bearing plate covering the bottom of the cavity and a baffle for opening or closing a third air vent. The load-bearing plate and the baffle are fixedly connected, and the baffle is slidably connected to the cavity body. The third air vent is disposed in the cavity body. When the load-bearing plate is in a non-load-bearing state, the load-bearing plate seals the bottom of the cavity, and the baffle is in a sealing fit with the side wall of the cavity body to close the third air vent. When the support body is in a load-bearing state, the load-bearing plate opens the cavity, and the baffle opens the third air vent, so that the insulation cavity communicates with the ventilation cavity through the cavity and the third air vent.

[0022] In one embodiment, the load-bearing plate and the baffle are integrally formed.

[0023] According to a second aspect of the present disclosure, a formula preparation device is also provided, including a warm air generating component and a housing component as described in any of the above embodiments, wherein the warm air generating component is disposed in a first housing and communicates with a ventilation cavity.

[0025] This formula preparation device utilizes the housing assembly of any of the above embodiments, enabling the use of a warm air generating component to deliver drying gas to the sterilization chamber. This facilitates rapid drying of the bottles during sterilization, improving sterilization efficiency. Furthermore, the device can deliver warming gas to the insulation chamber using the warm air generating component, allowing for heat preservation or heating within the chamber. This process keeps the bottles dry, making it more convenient to use. Thus, this formula preparation device combines drying and insulation functions without requiring a water-heating component, resulting in a more compact structure and facilitating miniaturization.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0045] With the improvement of living standards, people's demands for maternal and infant products are also increasing. To meet the growing childcare needs, a variety of smart home appliances have emerged on the market. Among them, multi-functional formula makers integrate functions such as formula preparation, warming, sterilization, drying, and storage, allowing users to perform these operations without needing multiple devices, providing great convenience and gaining popularity. However, with a wide variety of formula makers and brands available, consumers have many choices. How to win consumer favor and enhance product competitiveness has become an increasingly important issue for formula maker manufacturers.

[0046] In related technologies, formula preparation equipment requires multiple cavities to achieve different functions and necessitates corresponding functional components. For example, when formula preparation equipment has a sterilization cavity for sterilization and drying, and a warming cavity for warming or heating the milk, the warming or heating of the warming cavity is typically achieved through a water-based heating device, and the drying function is achieved through a fan-based heating device. This results in the shell assembly needing to incorporate functional cavities and integrate functional components, leading to a relatively large and bulky size, which is detrimental to the miniaturization of formula preparation equipment.

[0047] Therefore, it is necessary to provide a housing assembly. This housing assembly can utilize the ventilation cavity to supply gas to the insulation cavity and the disinfection cavity, eliminating the need for the related structures of the integrated water heating component, making the structure of the housing assembly more compact and helping to reduce the size of the housing assembly.

[0048] To better understand the housing assembly of this disclosure, it is illustrated by using a milk preparation device in which the housing assembly is applied.

[0049] like Figures 1 to 3 As shown, in some embodiments, a milk preparation device 10 is provided, including a warm air generating assembly 200 and a housing assembly 100. The housing assembly 100 includes a first housing 110, a second housing 120, a first air duct 130, and a second air duct 140. The first housing 110 has a ventilation chamber 111 and a heat preservation chamber 112 separated from the ventilation chamber 111. The first air duct 130 connects the ventilation chamber 111 and the heat preservation chamber 112. The second housing 120 is fixedly connected to the first housing 110 and has a sterilization chamber 121. The second air duct 140 connects the ventilation chamber 111 and the sterilization chamber 121. The warm air generating assembly 200 is disposed in the first housing 110 and communicates with the ventilation chamber 111.

[0050] When the formula preparation device 10 is in use, the warm air generating component 200, which generates warm air, is connected to the ventilation chamber 111. At this time, the ventilation chamber 111 is connected to the heat preservation chamber 112 via the first air duct 130. The ventilation chamber 111 is connected to the sterilization chamber 121 via the second air duct 140, facilitating the delivery of warm air generated by the warm air generating component 200 through the ventilation chamber 111 to the heat preservation chamber 112 for warming the formula, and / or to the sterilization chamber 121 for drying the bottles 20. When the formula preparation device 10 needs to use the heat preservation function, the warm air generating component 200 delivers heat preservation gas to the heat preservation chamber 112, thereby enabling the heat preservation chamber 112 to keep or heat containers such as bottles 20. Compared with traditional water-heating methods, this method keeps containers dry, eliminating the need to wipe water droplets from the outer walls, making it more convenient to use. When the formula preparation equipment 10 needs to use the drying function, the warm air generating component 200 supplies drying gas to the sterilization chamber 121, facilitating the rapid drying of containers such as the baby bottles 20 and improving the sterilization efficiency of the baby bottles 20. In this way, the housing assembly can use the ventilation chamber to provide gas to the heat preservation chamber and sterilization chamber, eliminating the need for integrated water heating components, making the housing assembly more compact and reducing its size. Since the formula preparation equipment 10 has both drying and heat preservation functions and does not require water heating components, its compact structure contributes to its miniaturization.

[0051] Understandably, the ventilation cavity 111 is designed to facilitate connection with the warm air generating component 200, enabling modular assembly of the housing component 100 and the warm air generating component 200, thereby improving the assembly efficiency of the milk preparation equipment 10. Simultaneously, the ventilation cavity 111 can also buffer the airflow delivered by the warm air generating component 200, helping to reduce wind noise.

[0052] It should be noted that the first housing 110 and / or the second housing 120 can be implemented in various ways, as long as the above-described structure is achieved. For example, they can be assembled from multiple housings or partitions. Another example is that they can be assembled from a housing and a cover plate. Yet another example is that they can be assembled from a cavity, a cover plate, and pipes. Yet another example is that the first and second housings can be formed by providing multiple partitions on the outer shell.

[0053] Furthermore, the first air duct 130 and / or the second air duct 140 can be formed by a shell or a partition, or by a pipe, without limitation.

[0054] like Figure 1 as well as Figure 2As shown, in some embodiments, the housing assembly 100 further includes a switching valve assembly 150, which is disposed in at least one of the first housing 110, the first air duct 130, the second housing 120, and the second air duct 140, so that the ventilation chamber 111 is connected to the insulation chamber 112 and / or the disinfection chamber 121 through the switching valve assembly 150. When the switching valve assembly 150 is in a first switching state, the ventilation chamber 111 is connected to the insulation chamber 112 and isolated from the disinfection chamber 121. When the switching valve assembly 150 is in a second switching state, the ventilation chamber 111 is connected to the disinfection chamber 121 and isolated from the insulation chamber 112. Thus, when the formula preparation equipment 10 needs to use the heat preservation function instead of the drying function, the switch valve assembly 150 switches to the first switching state, connecting the ventilation chamber 111 to the heat preservation chamber 112 while isolating it from the sterilization chamber 121. This allows the heat preservation gas generated by the warm air generating assembly 200 to be delivered to the heat preservation chamber 112 as much as possible, fully utilizing the heat preservation gas to keep or heat the containers such as the baby bottles 20 placed in the heat preservation chamber 112. Compared with traditional water heating methods, this method keeps the containers dry, eliminating the need to wipe water droplets off the outer walls, making it more convenient to use.

[0055] When the formula preparation equipment 10 needs to use the drying function instead of the heat preservation function, the switch valve assembly 150 switches to the second switching state, connecting the ventilation chamber 111 to the sterilization chamber 121 while isolating it from the heat preservation chamber 112. This allows the drying gas generated by the warm air generating assembly 200 to be delivered to the sterilization chamber 121 as much as possible, facilitating the rapid drying of containers such as the baby bottles 20 and improving the efficiency of container sterilization. In this way, the switch valve assembly 150 can selectively connect the ventilation chamber 111 to either the heat preservation chamber 112 or the sterilization chamber 121, avoiding the waste of warm air.

[0056] It should be noted that "the switch valve assembly 150 is disposed in at least one of the first housing 110, the first air duct 130, the second housing 120 and the second air duct 140" includes being disposed at the air inlet of the heat preservation chamber 112 and at least one of the first air duct 130 and at least one of the air inlet of the disinfection chamber 121 and the second air duct 140, or being disposed between the first air duct 130 and the second air duct 140, etc., as long as the above switching can be achieved.

[0057] like Figure 3As shown, in some embodiments, when the switching valve assembly 150 is in the third switching state, the ventilation chamber 111 is connected to the heat preservation chamber 112 and the sterilization chamber 121. Thus, when the formula preparation equipment 10 needs to use both the heat preservation and drying functions simultaneously, the switching valve assembly 150 switches to the third switching state, connecting the ventilation chamber 111 to both the heat preservation chamber 112 and the sterilization chamber 121. This allows the warm air generated by the warm air generating assembly 200 to be sent through the ventilation chamber 111 into the heat preservation chamber 112 for heat preservation or heating, and also allows the warm air to be sent into the sterilization chamber 121 to dry items such as the baby bottle 20.

[0058] It should be noted that the switching valve assembly 150 can be implemented in various ways, for example, by combining at least two two-way valves, or by combining a three-way or more switching valves.

[0059] like Figure 1 as well as Figure 2 As shown, the switching valve assembly 150 includes a first switching valve 151 disposed on the first air duct 130 and a second switching valve 152 disposed on the second air duct 140. When the switching valve assembly 150 is in a first switching state, the first switching valve 151 is open and the second switching valve 152 is closed. When the switching valve assembly 150 is in a second switching state, the first switching valve 151 is open and the second switching valve 152 is closed. In this way, the first switching valve 151 can be independently controlled to connect or close the ventilation chamber 111 and the insulation chamber 112, and the second switching valve 152 can be controlled to connect or close the ventilation chamber 111 and the disinfection chamber 121.

[0060] Optionally, such as Figure 3 As shown, in some embodiments, when the switching valve assembly 150 is in the third switching state, both the first switching valve 151 and the second switching valve 152 are in the open state.

[0061] It should be noted that the first switching valve 151 and the second switching valve 152 include valve 1532 structures such as two-way valves that can realize the on-off control of fluid channels.

[0062] like Figures 4 to 7As shown, in some embodiments, the switching valve assembly 150 includes a three-way valve 153. The three-way valve 153 includes a valve seat 1531 and a valve 1532 movably disposed on the valve seat 1531. The valve seat 1531 includes a first air outlet 1501 communicating with a first air duct 130, a second air outlet 1502 communicating with a second air duct 140, and an air inlet 1503 communicating with a ventilation cavity 111. When the three-way valve 153 is in a first switching state, the valve 1532 is in a first state, so that the first air outlet 1501 is connected to the air inlet 1503, while the second air outlet 1502 is disconnected from the air inlet 1503. When the three-way valve 153 is in a second switching state, the valve 1532 is in a second state, so that the first air outlet 1501 is disconnected from the air inlet 1503, while the second air outlet 1502 is connected to the air inlet 1503. Thus, when the formula preparation equipment 10 needs to use the heat preservation function, valve 1532 switches to the first state, so that the ventilation chamber 111 is connected to the heat preservation chamber 112 through the first air vent 1501 but not to the sterilization chamber 121, allowing the warm air generated by the warm air generating component 200 to be sent into the heat preservation chamber 112 through the ventilation chamber 111 for heat preservation or heating. When the formula preparation equipment 10 needs to use the drying function, valve 1532 switches to the second state, so that the ventilation chamber 111 is connected to the sterilization chamber 121 through the second air vent 1502 but not to the heat preservation chamber 112, allowing the warm air generated by the warm air generating component 200 to be sent into the sterilization chamber 121 through the ventilation chamber 111 to dry the bottles 20 and other items. The compact structure of the three-way valve 153 makes the structure of the housing assembly 100 more compact.

[0063] It should be noted that there are several ways to implement the feature that "valve 1532 is movably mounted on valve seat 1531," as long as it allows switching between the first and second states. For example, if valve 1532 is slidably connected to valve seat 1531, then the three-way valve 153 is a linear valve. Another example is that if valve 1532 is rotatably connected to valve seat 1531, then the three-way valve 153 is a rotary valve.

[0064] It should be noted that the three-way valve 153 can be implemented in various ways, including but not limited to at least one of manual valve, gravity switch valve and electric valve, as long as it can achieve the above-mentioned on / off control.

[0065] like Figure 7 as well as Figure 9As shown, in some embodiments, valve 1532 is rotatably mounted on valve seat 1531, and valve 1532 includes an arc-shaped guide surface 1504. When valve 1532 is in the first state, valve 1532 closes the second air outlet 1502 and guides the airflow to the first air outlet 1501 through the arc-shaped guide surface 1504. When valve 1532 is in the second state, valve 1532 closes the first air outlet 1501 and guides the airflow to the second air outlet 1502 through the arc-shaped guide surface 1504. Thus, when valve 1532 is in the first state, by using valve 1532 to close the second air outlet 1502 and by using the arc-shaped guide surface 1504 to guide the gas in ventilation cavity 111 to the first air outlet 1501, turbulence can be effectively reduced, energy loss of warm air can be reduced, and thus energy consumption of milk preparation equipment 10 can be reduced. When valve 1532 is in the second state (in conjunction with...), Figure 7 When the first air vent 1501 is closed (as shown), the valve 1532 can guide the gas in the ventilation cavity 111 to the second air vent 1502 using the arc-shaped guide surface 1504. This can effectively reduce turbulence and reduce the energy loss of the warm air, thereby helping to reduce the energy consumption of the milk preparation equipment 10.

[0066] like Figure 8 as well as Figures 10 to 12 As shown, optionally, in some embodiments, the switching valve assembly 150 further includes a driver 154 disposed in the first housing 110, the driver 154 being used to drive the valve 1532 to switch between a first state and a second state. Thus, the driver 154 enables the valve 1532 to switch between the first state and the second state, facilitating automatic control and improving the ease of use of the milk preparation equipment 10.

[0067] It should be noted that the actuator 154 can be implemented in various ways, and can be set according to the driving force required for the movement of the valve 1532, including expansion joints, rotary power sources, etc.

[0068] Optionally, in some embodiments, the valve 1532 is rotatably mounted on the shell body, and the actuator 154 includes a motor for driving the valve 1532 to rotate.

[0069] like Figure 8 as well as Figure 9As shown, in some embodiments, the housing assembly 100 further includes a cavity 160 fixedly connected to the first housing 110. The cavity 160 communicates with the insulation cavity 112. The cavity 160 is inserted into the ventilation cavity 111 and divides at least a portion of the ventilation cavity 111 into an annular flow channel 101. The annular flow channel 101 communicates with the first air duct 130 and the second air duct 140, respectively. In this way, the cavity 160 can increase the depth of the insulation cavity 112, making full use of the space within the ventilation cavity 111. The formation of the annular flow channel 101 within the ventilation cavity 111 can effectively reduce turbulence and reduce the energy loss of the warm air, thereby helping to reduce the energy consumption of the milk preparation equipment 10.

[0070] like Figure 9 As shown, in some embodiments, the bottom of the cavity 160 and the ventilation cavity 111 are spaced apart. In this way, when the milk preparation device 10 warms the milk, the outer wall of the cavity 160 is surrounded by the warming gas in the ventilation cavity 111, which helps to improve the heat uniformity of the heat preservation cavity 112.

[0071] like Figures 8 to 10 As shown, in some embodiments, the cavity 160 includes a cavity body 161 and a support body 162. The cavity body 161 is fixedly connected to the first housing 110, and the cavity body 161 has a through cavity 1611 communicating with the heat preservation cavity 112. The support body 162 covers the bottom of the through cavity 1611. At least one of the support body 162 and the cavity body 161 has a third air vent 1601. The support body 162 is slidably connected to at least one of the first housing 110 and / or the cavity body 161, and has a load-bearing state with the third air vent 1601 open and a non-load-bearing state with the third air vent 1601 closed. Thus, when the milk preparation device 10 needs to use the heat preservation function, the container such as the milk bottle 20 is placed in the heat preservation cavity 112, and the weight of the container acts on the support body 162, allowing the support body 162 to switch to the load-bearing state. At this time, the ventilation cavity 111 is connected to the insulation cavity 112 through the third air vent 1601, which facilitates the delivery of gas in the annular guide channel 101 to the insulation cavity 112 through the third air vent 1601. Furthermore, the insulation cavity 112 delivers insulation gas through the first air duct 130 and the third air vent 1601, which is located differently from the first air duct 130, which helps improve the uniformity of heating of the container within the insulation cavity 112.

[0072] In some embodiments, the carrier 162 can be reset to a non-carrying state. Thus, when the milk preparation equipment 10 does not need to use the heat preservation function, the container can be removed from the carrier 162, allowing the carrier 162 to reset to a non-carrying state, thereby closing the third air vent 1601 and further improving the convenience for users to use the milk preparation equipment 10.

[0073] It should be noted that there are several ways to achieve the goal of "the carrier 162 being able to be reset to a non-carrying state", including electric reset, repositioning, magnetic reset, magnetic repulsion reset, elastic reset, etc.

[0074] Understandably, when the third air vent 1601 is disposed on the cavity body 161, the third air vent 1601 is opened or closed via the carrier 162. And / or, when the third air vent 1601 is disposed on the carrier 162, the third air vent 1601 is opened or closed via the cavity body 161.

[0075] Optionally, such as Figure 6 , Figure 7 as well as Figure 9 As shown, in some embodiments, the housing assembly 100 further includes a reset member 170. The reset member 170 is disposed between the carrier 162 and the first housing 110 to allow the carrier 162 to reset to a non-load-bearing state. When the carrier 162 is in a load-bearing state, the third vent 1601 is opened, allowing the insulation chamber 112 to communicate with the ventilation chamber 111 through the third vent 1601. Thus, when the formula preparation device 10 needs to use the insulation function, a container such as a bottle 20 is placed in the insulation chamber 112, and the weight of the container acts on the carrier 162. At this time, the reset member 170 generates a reset force less than the weight of the container. When the formula preparation device 10 does not need to use the insulation function, the container is removed from the carrier 162, allowing the carrier 162 to reset to a non-load-bearing state through the reset force generated by the reset member 170, thereby closing the third vent 1601.

[0076] It should be noted that the reset component 170 includes a magnetically attracted reset component 170, a magnetically repelled reset component 170, and an elastic reset component 170, etc. For example... Figure 7 As shown, in this embodiment, the reset member 170 is a compression spring.

[0077] Furthermore, such as Figure 6 as well as Figure 7As shown, in some embodiments, the support body 162 includes a load-bearing plate 1621 covering the bottom of the cavity 1611 and a baffle 1622 for opening or closing the third air vent 1601. The load-bearing plate 1621 and the baffle 1622 are fixedly connected, and the baffle 1622 is slidably connected to the cavity body 161. The third air vent 1601 is disposed in the cavity body 161. When the load-bearing plate is in a non-load-bearing state, the load-bearing plate 1621 seals the bottom of the cavity 1611, and the baffle 1622 is sealed to the side wall of the cavity body 161 to close the third air vent 1601. When the support body 162 is in a load-bearing state, the load-bearing plate 1621 opens the cavity 1611, and the baffle 1622 opens the third air vent 1601, so that the insulation cavity 112 communicates with the ventilation cavity 111 through the cavity 1611 and the third air vent 1601. Thus, when the formula preparation equipment 10 needs to use the heat preservation function, the container such as the bottle 20 is placed into the heat preservation chamber 112, and the weight of the container acts on the support plate, causing the support plate to move downward, opening the ventilation chamber 1611, and driving the baffle 1622 to open the third air vent 1601. At this time, the ventilation chamber 111 is connected to the heat preservation chamber 112 through the third air vent 1601, which facilitates the delivery of gas in the annular guide channel 101 to the heat preservation chamber 112 through the third air vent 1601. Furthermore, the heat preservation chamber 112 delivers heat preservation gas through the first air duct 130 and the third air vent 1601, which is located differently from the first air duct 130, which helps to improve the uniformity of heating of the container within the heat preservation chamber 112. When the formula preparation equipment 10 does not need to use the heat preservation function, the container is removed from the support body 162, allowing the support body 162 to return to its non-load-bearing state, thereby closing the third air vent 1601.

[0078] Optionally, the load-bearing plate 1621 and the baffle 1622 are integrally formed. This reduces assembly steps and improves the assembly efficiency of the housing assembly 100.

[0079] Optionally, such as Figures 8 to 10 As shown, a portion of the third air vent 1601 is disposed on the cavity body 161, and is opened or closed using a baffle 1622. Figure 10 As shown, a portion of the third air vent 1601 is disposed on the carrier 162, and the cavity body 161 is used to open or close the third air vent 1601. For example, two adjacent baffles 1622 are spaced apart to form the third air vent 1601. The cavity body 161 is also provided with baffles 1622 and is disposed between two adjacent third air vents 1601. In this case, the baffles 1622 on the cavity body 161 can be used to open or close the third air vent 1601 on the carrier 162.

[0080] like Figure 11 as well as Figure 12As shown, in some embodiments, the first housing includes an air inlet 1111 for connecting the warm air generating assembly 200. One end of the annular guide channel 101 is connected to the air inlet 1111, and the other end is connected to the first air duct 130 and the second air duct 140. Thus, the warm air generated by the warm air generating assembly 200 enters the annular guide channel 101 through the air inlet 1111 and is guided to the first air duct 130 and / or the second air duct 140 through the annular guide channel 101, so that at least part of the warm air can surround the cavity 160, and part of the sidewall of the cavity 160 can be surrounded by the warm air, which is beneficial to improving the heat distribution uniformity of the insulation cavity 112.

[0081] It should be noted that the temperature of the "warm air" can be flexibly set according to the required milk-warming temperature of the insulation cavity 112. For example, 37℃~50℃, 37℃~40℃, 38℃~42℃, etc.

[0082] It should be noted that the warm air generating component 200 can be implemented in various ways, as long as it can produce warm air suitable for warming milk. For example, it can be a heater 210, a blower, etc.

[0083] like Figure 12 As shown, in some embodiments, the warm air generating assembly 200 includes a fan 210 and a heating element 220, the heating element 220 being disposed between the outlet of the fan 210 and the air inlet 1111.

[0084] It should be noted that the "heating element" can be any existing heating device capable of achieving the above functions, such as heating tubes, PTC (Positive Temperature Coefficient, heating element), etc.
