Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0039] In one embodiment, such as Figures 1 to 3 As shown, this application embodiment provides a liquid storage module 100, which specifically includes a liquid storage tank 110 and a module housing 120 having a receiving cavity 11. The liquid storage tank 110 is provided with a first suction head 111. The module housing 120 is provided with a second suction head 121, which is used to connect to a liquid suction device of a cooking device. When the liquid storage tank 110 is installed in the receiving cavity 11, the second suction head 121 is correspondingly connected to the first suction head 111.

[0040] It is understood that the liquid storage module 100 of this application embodiment is mainly used in cooking equipment to store liquids such as starch required during the cooking process. Generally, liquids such as starch are mainly stored in the liquid storage tank 110. To facilitate the easy removal of the liquid storage tank 110 for replenishment, the liquid storage tank 110 is mainly installed in the accommodating cavity 11 using a detachable connection. The first extraction head 111 mentioned above can be either integrally formed with the liquid storage tank 110 or detachably installed on the liquid storage tank 110. Similarly, the second extraction head 121 mentioned above can be either integrally formed with the module housing 120 or detachably installed on the module housing 120. When the liquid storage module 100 is installed in the corresponding cooking equipment, the second extraction head 121 can be kept in communication with the liquid suction device of the cooking equipment. At this time, when the liquid storage tank 110 is installed in the accommodating cavity 11, the first extraction head 111 and the second extraction head 121 can be connected accordingly. The liquid suction device of the cooking equipment can then extract the liquid in the liquid storage tank 110 through the second extraction head 121 and the first extraction head 111 in sequence to perform the corresponding liquid addition operation.

[0041] In addition, to facilitate the installation of the liquid storage tank 110 in the receiving cavity 11, the first extraction head 111 can quickly connect with the second extraction head 121. One of the first extraction head 111 and the second extraction head 121 is preferably a magnetic extraction male head, and the other is preferably a magnetic extraction female head. This allows the liquid storage tank 110 to quickly connect with the second head through magnetic attraction when installed in the receiving cavity 11. Furthermore, the modification of both the first extraction head 111 and the second extraction head 121 to a magnetic structure effectively reduces liquid dripping when placing or removing the liquid storage tank 110.

[0042] In this way, the liquid storage module 100 provided in this application embodiment can form a modular assembly structure through the above-described structural configuration. That is, all its components can be installed in the module housing 120 to form an integral liquid storage module 100. Then, the module housing 120 is installed in the cooking equipment as a whole. This allows the entire liquid storage module 100 to be quickly disassembled from the corresponding cooking equipment when it is necessary to replace its components during subsequent maintenance, so as to carry out the corresponding maintenance or replacement operations, thereby greatly improving the user experience.

[0043] In some examples, such as Figure 2 and Figure 4 As shown, a side opening 12 is provided on one side of the module housing 120, and the liquid storage tank 110 is inserted and installed in the receiving cavity 11 through the side opening 12. In this way, the liquid storage tank 110 can be quickly removed from the corresponding receiving cavity 11 by side extraction, so as to facilitate the corresponding liquid replenishment operation.

[0044] In some examples, such as Figures 1 to 6 As shown, the first extraction head 111 and the second extraction head 121 are inclined towards the direction in which the liquid storage tank 110 is inserted into the receiving cavity 11. Thus, with this structural arrangement, the liquid storage tank 110 can be quickly accessed and removed from the corresponding receiving cavity 11 by side extraction, ensuring that the first extraction head 111 and the second extraction head 121 are guided without collision or interference. Furthermore, with the direction in which the liquid storage tank 110 is inserted into the receiving cavity 11 as a reference, the inclination angle of the extraction direction of the first extraction head 111 and the second extraction head 121 is both -90° to +90°. Thus, with these parameter settings, the liquid storage tank 110 can be quickly accessed and removed from the corresponding receiving cavity 11 by side extraction, further ensuring that the first extraction head 111 and the second extraction head 121 are guided without collision or interference.

[0045] In some embodiments, the inclination angle of the liquid extraction direction of the first extraction head 111 and the second extraction head 121 is -90° to +90°, including integer or non-integer angles within the range.

[0046] Understandably, to better achieve the inclined arrangement of the first extraction head 111 and the second extraction head 121, a first inclined surface 112 is preferably provided on the top side of the liquid storage tank 110 to correspondingly install the first extraction head 111, and a second inclined surface 122 is provided on the top side of the module housing 120 to correspondingly install the second extraction head 121. The first inclined surface 112 and the second inclined surface 122 are arranged opposite each other, and their inclinations are the same. In addition, to enable the first extraction head 111 to better collect all the liquid in the liquid storage tank 110, a extraction pipe 113 is also connected to the end of the first extraction head 111 away from the second extraction head 121, and the end of the extraction pipe 113 away from the first extraction head 111 extends to the vicinity of the bottom side of the liquid storage tank 110.

[0047] In some examples, such as Figures 4 to 6 As shown, the first extraction head 111 has displacement space relative to the liquid storage tank 110. Thus, this structural arrangement ensures that both the first extraction head 111 and the second extraction head 121 have sufficient space to move smoothly during the suction and separation processes. Similarly, the second extraction head 121 has displacement space relative to the module housing 120. Thus, this structural arrangement also ensures that both the first extraction head 111 and the second extraction head 121 have sufficient space to move smoothly during the suction and separation processes.

[0048] It is understandable that in this example, the first extraction head 111 has displacement space relative to the liquid storage tank 110 and the second extraction head 121 has displacement space relative to the module housing 120. Only one of them can exist, or both can exist simultaneously, so as to better ensure that the first extraction head 111 and the second extraction head 121 have sufficient room to move smoothly during the process of suction and separation.

[0049] In some examples, such as Figures 4 to 6 As shown, at least one of the first extraction head 111 and the second extraction head 121 is mounted using a stepped screw 114. Thus, with the above structural arrangement, when the first extraction head 111 is mounted to the liquid storage tank 110 using the stepped screw 114, it allows for displacement space relative to the liquid storage tank 110; and when the second extraction head 121 is mounted to the module housing 120 using the stepped screw 114, it allows for displacement space relative to the module housing 120.

[0050] Understandably, with Figure 5 and Figure 6As shown, taking the first extraction head 111 mounted on the liquid storage tank 110 via a stepped screw 114 as an example, this illustrates how the stepped screw 114 provides a corresponding displacement space. Specifically, the first extraction head 111 is movably connected to the first inclined surface 112 via at least one stepped screw 114. A first limiting position is formed on one side by the nut protrusion of the stepped screw 114 itself, and a second limiting position is formed on the other side by the cooperating nut. These two limiting positions work together, allowing the screw of the stepped screw 114 to move along its length relative to the first inclined surface 112, thereby driving the first extraction head 111 and providing displacement space relative to the liquid storage tank 110. For those skilled in the art, other methods can also be used to provide displacement space between the first extraction head 111 and the liquid storage tank 110, and / or, between the second extraction head 121 and the module housing 120. Specifically, at least one of the liquid storage tank 110 and the module housing 120 may be provided with a flexible mounting platform for mounting at least one of the first extraction head 111 and the second extraction head 121. In this way, the corresponding displacement space can be ensured by the flexible mounting platform itself having a certain amount of elastic movement in its installation direction.

[0051] In some examples, such as Figure 1 and Figure 2 As shown, the liquid storage tank 110 also includes a liquid chamber 115, a front cover 116, and a top cover 117, with at least one of the front cover 116 and the top cover 117 being detachably connected to the liquid chamber 115. Thus, this structural arrangement allows at least one of the front cover 116 and the top cover 117 to be opened relative to the liquid chamber 115, facilitating the operator's replenishment of the liquid chamber 115.

[0052] It is understood that the detachable configuration in this example can specifically mean that the liquid chamber 115 can be detached from one of the face cover 116 and the top cover 117 through a snap-fit ​​structure, sliding connection structure or rotating connection structure, so that at least one of the face cover 116 and the top cover 117 can be opened and closed relative to the liquid chamber 115.

[0053] In some examples, such as Figure 1 and Figure 2As shown, the module housing 120 has a housing frame 123 along the edge of the side opening 12. When the liquid storage tank 110 is inserted into the receiving cavity 11 through the side opening 12, the face cover 116 covers the side opening 12, and the face cover 116 and the housing frame 123 are on the same plane. Thus, with this structural arrangement, the panel of the liquid storage tank 110 serves as the door panel of the module housing 120 (a structure used to cover the side opening 12 and close the receiving cavity 11). This allows the liquid storage tank 110 to be retrieved or placed from the corresponding receiving cavity 11, simultaneously completing the opening and closing operation of the door panel of the module housing 120 (i.e., covering or opening the side opening 12). This improves the convenience of retrieving and placing the liquid storage tank 110 from the corresponding receiving cavity 11 and avoids the problem of frequent opening of the hinged door panel in existing equipment, which could easily damage the door panel. In addition, since the liquid storage tank 110 is inserted into the accommodating cavity 11 through the side opening 12, the cover 116 is also located on the same plane as the outer shell frame 123. This ensures the sealing performance of the cover 116 to the side opening 12, while making the appearance of the entire liquid storage module 100 more aesthetically pleasing.

[0054] In some examples, such as Figure 3 and Figure 4 As shown, a transparent detection window 118 is provided on the surface of the liquid storage tank 110. The liquid storage module 100 also includes a liquid level detector 130. The transparent detection window 118 and the liquid level detector 130 are correspondingly arranged to monitor the liquid level in the liquid storage tank 110. Thus, through the above structural arrangement, relevant operators can promptly obtain the liquid level in the liquid storage tank 110 through the liquid level detector 130, so that when the liquid level in the liquid storage tank 110 is low, the liquid storage tank 110 can be removed in a timely manner for appropriate liquid replenishment.

[0055] Understandably, the liquid level detector 130 in this example is primarily a photoelectric liquid sensor, used in conjunction with the transparent detection window 118 to accurately detect the liquid level within the liquid storage tank 110. Generally, when the liquid level in the liquid storage tank 110 is lower than the transparent detection window 118, the photoelectric signal emitted by the liquid level detector 130 towards the transparent detection window 118 and then back changes, indicating that the liquid level in the liquid storage tank 110 is below a preset threshold, requiring the relevant operators to replenish the liquid.

[0056] In some examples, such as Figure 3 and Figure 4As shown, a magnetic stirrer is installed on the bottom side of the liquid storage tank 110, and a motor assembly 140 is correspondingly installed on the bottom of the module housing 120. The motor assembly 140 drives the magnetic stirrer to rotate when the liquid storage tank 110 is installed in the receiving cavity 11. Thus, with the above structural arrangement, when the liquid storage tank 110 contains liquids such as starch that may settle after a long period of stillness, the magnetic stirrer driven by the motor assembly 140 can be rotated to stir the liquid stored in the liquid storage tank 110, ensuring that the liquid does not settle. Furthermore, the motor assembly 140 is fixedly installed on the bottom of the module housing 120. Thus, with the above structural arrangement, the connection between the motor assembly 140 and the module housing 120 is ensured to be stable.

[0057] In some examples, such as Figure 8 and Figure 9 As shown, a mounting base 124 is movably disposed at the bottom of the module housing 120, allowing the mounting base 124 to be separated from the bottom of the module housing 120, and the motor assembly 140 is mounted on the mounting base 124. Thus, this structural arrangement enables quick assembly and disassembly of the motor assembly 140, effectively improving the efficiency of assembly and disassembly, and facilitating operators to perform corresponding disassembly and maintenance of the electrode assembly at any time.

[0058] It is understood that in this example, the bottom of the module housing 120 and the mounting base 124 can be moved between each other via a sliding connection between the groove 125 and the slide rail 126. That is, one of the groove 125 and the slide rail 126 is mounted on the bottom of the module housing 120, and the other is mounted on the mounting base 124. This allows the mounting base 124 to slide relative to the bottom of the module housing 120, thereby enabling the mounting base 124 to drive the motor assembly 140, which may be positioned on or separated from the bottom of the module housing 120.

[0059] In some examples, such as Figure 8 and Figure 9 As shown, the module housing 120 has a guide groove 127 on at least one side adjacent to the second extraction head 121. Thus, with this structural arrangement, when the liquid storage module 100 is installed in the corresponding cooking equipment, the guide groove 127 can create appropriate space clearance, and the guide groove 127 can also guide quick alignment, so that the module housing 120 can be better installed in the corresponding position in the cooking equipment.

[0060] In one embodiment, this application also provides a cooking device, which includes a device body and a liquid storage module 100 as described in the above embodiment. The liquid storage module 100 is installed in the device body, and at least one side of the liquid storage module 100 is on the same plane as the device body.

[0061] It is understood that the aforementioned liquid storage module 100 is installed in the main body of the device, and at least one side of the liquid storage module 100 is on the same plane as the main body of the device. Specifically, this means that when the liquid storage module 100 is installed in the main body of the device, it can be perfectly embedded in the surface of the corresponding side of the main body of the device to ensure the overall aesthetics of the cooking device. Generally, it is preferable that the side of the liquid storage module 100 with the cover 116 is on the same plane as the corresponding side surface of the main body of the device to facilitate the placement and removal of the liquid storage tube.

[0062] Since the cooking device of this application embodiment adopts the liquid storage module 100 of the above-mentioned application embodiment, it has the same technical effect, which will not be repeated here.

[0063] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
