DETAILED DESCRIPTION

[0031] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, components, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, components, or characteristics in one or more embodiments may be combined in any suitable form.

[0032] The present invention proposes a multifunctional baby food machine, which improves the structure of the cooking pot 100 and the connection method between the cooking pot 100 and the stirring cup 200, so that the multifunctional baby food machine of the present invention can select the working state of the baby food machine according to the use requirements. When the baby food machine is in a cooperative working state, the cooking pot 100 can provide high-temperature steam to the stirring cup 200 to steam the ingredients in the stirring cup 200; when the baby food machine is in an independent working state, the cooking pot 100 no longer provides high-temperature steam to the stirring cup 200, but acts as a functional component (such as an ordinary cooking pot, etc.) to steam the food in the pot, and the stirring cup 200 can also independently stir the food in the stirring cup.

[0033] Specifically, combined Figures 1 to 12As shown, the multifunctional baby food machine includes a machine base 300, a cooking pot 100 and a blending cup 200, wherein the cooking pot 100 includes a steam generator 130 and a pot cover, and the blending cup 200 includes a cup assembly 220 and a cup cover 210; the cup cover 210 is provided with a steam inlet pipe 211; the pot cover includes an inner cover 120 and an outer cover 110 rotatably arranged on the outer side of the inner cover 120, the inner cover 120 is provided with a steam supply channel 121 and a first steam exhaust port 122, and the outer cover 110 is provided with a notch 111 and a second steam exhaust port 113; the outer cover 110 has an open position and a closed position relative to the inner cover 120, wherein the open position is that the steam supply channel 121 is exposed from the notch 111 and the first steam exhaust port 122 is open. 2 is staggered with the second steam exhaust port 113, and the closed position is that the steam supply channel 121 is staggered with the notch 111 and the first steam exhaust port 122 is connected with the second steam exhaust port 113; the multifunctional baby food machine has an independent working state in which the stirring cup 200 is not connected with the cooking pot 100 and a coordinated working state in which the stirring cup 200 is connected with the cooking pot 100; when the multifunctional baby food machine is in the independent working state, the outer cover 110 is in the closed position, and the steam inlet pipe 211 is staggered with the steam supply channel 121; when the multifunctional baby food machine is in the coordinated working state, the outer cover 110 is in the open position, and the steam inlet pipe 211 is connected with the steam supply channel 121.

[0034] The multifunctional baby food machine of the present invention has an outer cover that is rotatably arranged on the outer side of the inner cover. By controlling the outer cover to rotate relative to the inner cover, the outer cover is placed in an open position or a closed position, thereby controlling the baby food machine to be in a coordinated working state or an independent working state. When the baby food machine is in a coordinated working state, the steam supply channel is exposed in the notch and the first steam exhaust port and the second steam exhaust port are staggered, and the steam supply channel is connected with the steam inlet pipe, so that the cooking pot inputs high-temperature steam to the mixing cup through the steam supply channel and the steam inlet pipe; and when the baby food machine is in an independent working state, the steam supply channel and the steam inlet pipe are staggered (that is, the steam supply channel and the steam inlet pipe are not connected), the steam supply channel and the notch are staggered, and the first steam exhaust port and the second steam exhaust port are connected, so that the cooking pot no longer outputs steam to the mixing cup, but acts as a separate functional component to steam the food in the cooking pot, and discharges steam to the outside through the first steam exhaust port and the second steam exhaust port. The multifunctional baby food machine disclosed in the present invention abandons the connection method of directly docking the cooking pot and the stirring cup in the prior art, and innovatively controls the outer cover to rotate relative to the inner cover so that the outer cover is in a closed position or an open position, so that the baby food machine is in an independent working state or a cooperative working state, thereby allowing the multifunctional baby food machine to control its working state according to the user's usage requirements, so that the multifunctional baby food machine of the present invention can better meet the market demand.

[0035] As a usage scenario where the user needs the food supplement machine to cooperate with the work, the user adds liquid (drinking water or broth and other liquids) into the steam generator of the cooking pot, and tightens the pot cover on the steam generator to prevent the steam generated in the steam generator from leaking through the connection between the steam generator and the pot cover. The user then adds the food to be cooked into the cup assembly of the blender cup, and tightens the cup cover on the cup assembly. The user places the cooking pot and the blender cup on the machine base, and assembles the cooking pot and the blender cup in place. At this time, by controlling the outer cover to rotate relative to the inner cover, the steam supply channel is exposed to the notch and connected to the steam inlet pipe, and the first steam exhaust port is staggered with the second steam exhaust port. After the cooking pot is powered on, the electric heating element in the steam generator heats the liquid and generates high-temperature steam, which is output to the blender cup through the steam supply channel and the steam inlet pipe to cook the food in the blender cup, so that during subsequent processing, the blender in the blender cup stirs the steamed food under the drive of the motor in the machine base. It should be noted that the food can be first blended in a blending cup and then steamed by a cooking pot to provide high-temperature steam.

[0036] As a usage scenario where the user needs the food supplement machine to work independently, the user adds the food and liquid (drinking water or broth and other liquids) to be cooked into the steam generator of the cooking pot, and tightens the lid on the steam generator to prevent the steam generated in the steam generator from leaking through the connection between the steam generator and the lid. The user places the cooking pot on the machine base and assembles the cooking pot in place. At this time, by controlling the outer cover to rotate relative to the inner cover, the steam supply channel and the notch are misaligned, and the first exhaust port is connected to the second exhaust port. After the cooking pot is powered on, the electric heating element in the steam generator heats the liquid and generates high-temperature steam to cook the food in the cooking pot. The high-temperature steam is discharged through the first exhaust port and the second exhaust port, so that the cooking pot acts as a separate functional component to cook the food in the cooking pot. At this time, the stirring cup can also be placed on the machine base as a separate functional component for stirring.

[0037] In one embodiment, the first steam exhaust port 122 is disposed on the upper end surface of the inner cover 120, and the second steam exhaust port 113 is disposed on the upper end surface of the outer cover 110. When the multifunctional baby food machine of the present invention is in an independent working state, the high-temperature steam discharged from the cooking pot through the first and second steam exhaust ports is discharged from the top of the cooking pot, avoiding the risk of scalding caused by steam discharged from the side.

[0038] Preferably, a second sealing ring 122a is provided on the first steam exhaust port 122. When the outer cover 110 is in the open position, the upper end of the second sealing ring 122a is sealed and connected to the inner side surface of the outer cover 110; when the outer cover 110 is in the closed position, the second sealing ring is connected to the second steam exhaust port. The present invention provides a second sealing ring on the first steam exhaust port, so that when the outer cover is in the open position, it can ensure that high-temperature steam is input into the mixing cup through the steam supply channel without leaking through the first steam exhaust port and the inner side surface of the outer cover.

[0039] In one embodiment, an elastic member is provided between the outer cover 110 and the inner cover 120 to keep the outer cover 110 in the closed position in the independent working state. The present invention uses the elastic member to allow the outer cover to automatically reset to the closed position when the baby food machine is in the independent working state, so that the steam supply channel and the notch are staggered and the first and second steam exhaust ports are connected, thereby closing the steam supply channel and ensuring that the high-temperature steam of the steam cooker is discharged through the first and second steam exhaust ports, thereby preventing the user from being scalded by the high-temperature steam when forgetting to switch the open position or the closed position of the outer cover.

[0040] Furthermore, the elastic member is a tension spring or a torsion spring. The middle of the outer cover 110 is rotatably connected to the pivot hole in the middle of the inner cover 120 through a pivot shaft 140, a torsion spring is sleeved on the pivot shaft 140, and the two ends of the torsion spring are respectively fixedly connected to the inner cover 120 and the outer cover 110, so that when in an independent working state, the outer cover can be reset to a closed position under the elastic force of the torsion spring.

[0041] In one embodiment, the steam supply channel 121 is provided on the side wall of the inner cover 120, the notch 111 is provided on the side wall of the outer cover 110, and the steam inlet pipe 211 is provided on the side wall of the cup cover 210. In the present invention, by providing the steam supply channel on the side wall of the inner cover and the steam inlet pipe on the side wall of the cup cover, the steam supply channel and the steam inlet pipe are connected and communicated in the transverse direction, so as to facilitate the docking of the cooking pot and the stirring cup.

[0042] In one embodiment, the steam supply channel 121 includes a first through hole 121a provided on the side wall of the inner cover 120 and a first sealing ring 121b provided in the first through hole 121a; when the baby food machine is in the cooperative working state, the end of the steam inlet pipe 211 is inserted into the first sealing ring 121b. The present invention can improve the connection sealing and connection strength between the steam inlet pipe and the first sealing ring by providing the first sealing ring 121b in the first through hole 121a and connecting it with the end of the steam inlet pipe 211, thereby preventing steam from leaking from the connection between the steam inlet pipe and the first sealing ring.

[0043] Furthermore, the end face of the steam inlet pipe 211 is provided with a guiding bevel 211a; the end of the first sealing ring 121b protrudes out of the first through hole 121a, and the end face of the first sealing ring 121b is provided with a deformation groove 1211. The end of the first sealing ring of the present invention protrudes out of the first through hole. When the end of the steam inlet pipe is inserted into the first sealing ring, the deformation groove on the first sealing ring is elastically deformed by the guiding bevel at the end of the steam inlet pipe, so that the steam inlet pipe and the first sealing ring are interference-fitted, thereby improving the connection stability and sealing performance of the steam inlet pipe and the first sealing ring. In addition, the end of the first sealing ring protrudes out of the first through hole so that it can be elastically deformed better when docking with the steam inlet pipe, increasing the interference amount, and the end of the first sealing ring is arranged in a plane, which can be conveniently docked with the steam inlet pipe, thereby increasing the stability of the connection between the steam inlet pipe and the first sealing ring.

[0044] In one embodiment, it further includes a linkage member 114 disposed in the notch 111. The linkage member 114 is staggered with the first sealing ring in the open position so that the first sealing ring is exposed outside the notch 111. The linkage member 114 abuts against the end of the first sealing ring 121b in the closed position. In the present invention, since the first sealing ring is disposed at the first through hole, a linkage member is added in the notch so that the linkage member abuts against the end of the first sealing ring when the outer cover is in the closed position to close the steam supply channel. When the outer cover is in the closed position, the linkage member is staggered with the first sealing ring to open the steam supply channel.

[0045] In one embodiment, the linkage member 114 includes a root 114a connected to the notch 111 and a trigger end 114b extending from the root 114a, and the trigger end 114b protrudes out of the side wall of the outer cover 110. The trigger end of the present invention protrudes out of the side wall of the outer cover, and the first circumferential line where the trigger end is located intersects with the second circumferential line where the end of the steam inlet pipe is located. By rotating the cup cover of the blender cup, the cup cover drives the steam inlet pipe to rotate. When the end of the steam inlet pipe abuts against the trigger end, the steam inlet pipe pushes the linkage member to move, thereby driving the outer cover to rotate relative to the inner cover, so that the outer cover rotates from the closed position to the open position. At this time, the first sealing ring is exposed in the groove and is sealed and connected to the steam inlet pipe.

[0046] It should be noted that, regarding how to drive the outer cover to rotate from the closed position to the open position, the cup cover and the cup assembly are connected by a screw-on method. The present invention can first place the cooking pot on the designated assembly position of the cooking pot on the machine base, and then screw the cup cover to drive the steam inlet pipe to rotate during the rotation process, and drive the outer cover to rotate relative to the inner cover with the help of the steam inlet pipe, so that the first sealing ring is exposed in the groove and is sealed with the steam inlet pipe, and the cooking pot and the stirring cup are docked. In addition, the cup assembly of the present invention is connected to the machine base by a screw-on method. The present invention can also place the cooking pot on the designated assembly position of the cooking pot on the machine base, and screw the cup cover onto the cup assembly, and then screw the cup assembly to drive the steam inlet pipe to rotate during the rotation process, and drive the outer cover to rotate relative to the inner cover with the help of the steam inlet pipe, so that the first sealing ring is exposed in the groove and is sealed with the steam inlet pipe, and the cooking pot and the stirring cup are docked. In addition to the above method, the present invention can also rotate the outer cover from the closed position to the open position by manually rotating the outer cover.

[0047] In one embodiment, a limit plate 123 is provided on the side wall of the inner cover 120, and the limit plate 123 is located on one side of the first through hole 121a. A sliding groove 123a is provided on the limit plate 123, and the linkage member 114 is arranged through the sliding groove 123a. The present invention ensures the reliability of switching between the inner cover and the outer cover between the closed position and the open position by arranging the sliding groove on the limit plate and allowing the linkage member to pass through the sliding groove.

[0048] In one embodiment, the side wall of the inner cover 120 is further provided with two oppositely arranged enclosures 124, the first through hole 121a is located between the two enclosures 124, the limit plate 123 is located at one end of the two enclosures 124, and the other end of the two enclosures 124 forms a guide groove 124a. In the present invention, when the baby food machine rotates from an independent working state to a cooperative working state, the steam inlet pipe 211 enters the guide groove 124a, and is guided to dock with the steam supply channel 121 by the guide groove 124a, and the guide slope 211a at the end of the steam inlet pipe 211 is used to abut against the first sealing ring 121b, and the first sealing ring 121b undergoes elastic deformation according to the deformation groove 1211 so that the end of the steam inlet pipe 211 is just stuck or inserted into the end of the first sealing ring 121b. In addition, the two enclosures 124 limit the linkage member 114 to prevent the linkage member 114 from being skewed and stuck in the sliding groove 123a, thereby ensuring the reliability of the outer cover 110 switching between the open position and the closed position relative to the inner cover 120.

[0049] In one embodiment, both of the two enclosures 124 are provided with an anti-slip portion 124b extending from one of the enclosures 124 toward the other enclosure 124; the end of the steam inlet pipe 211 is provided with a circumferentially extending protrusion 211b, and when the steam inlet pipe moves in the axial direction under the action of an external force, the anti-slip portion abuts against the protrusion. The present invention provides anti-slip portions on both of the enclosures, and utilizes two anti-slip portions to limit the movement of the steam inlet pipe in the axial direction, thereby preventing the steam inlet pipe from loosening from the first sealing ring under the action of an external force, thereby improving the connection stability. It should be noted that the axial direction refers to the axis where the steam inlet pipe is located.

[0050] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
