TECHNICAL FIELD

[0002] The present application relates to the technical field of water purification equipment, in particular to an ice maker, a multifunctional water purifier and a functional water machine. BACKGROUND

The ice maker of the ice water purifying machine can take out the prepared ice cubes through the built-in ice taking module after ice making. However, the ice maker of the existing ice water purifying machine will have a certain amount of water accumulated during ice making and ice storage. The accumulated water may be the remaining water after ice making or the water melted from the ice cubes. If the generated water is not discharged in time, it will affect the normal operation of the ice maker. SUMMARY

[0053] Referring to Fig. 1, the present application provides a multifunctional water purifier, which comprises an ice maker 100, a water purifier 200 and a raw water tank 300. The raw water tank 300 is used to store un-purified water such as tap water, and the water in the raw water tank 300 can be supplied to the water purifier 200. The supplied water is filtered by a filter assembly of the water purifier 200 and then stored in a purified water tank of the water purifier 200. The purified water can be supplied to the ice maker 100 as a water source for making ice cubes C via the purified water tank. Therefore, the ice maker 100, the water purifier 200 and the raw water tank 300 can be connected in water circuit and electric circuit, and the skilled person in the art can select a desired way to assemble the ice maker 100, the water purifier 200 and the raw water tank 300 according to actual needs, which is not limited herein.

[0054] Referring to Figs. 2 to 11, as to the ice maker 100, the ice maker 100 can comprise a main body 1000, and a liquid storage cavity 1100, an ice making cavity 1200 and an ice storage cavity 1300 are arranged in the main body 1000. The liquid storage cavity 1100 is in communication with the ice making cavity 1200, and the ice making cavity 1200 is in communication with the ice storage cavity 1300. The main body 1000 is provided with a removal port 1302 in communication with the ice storage cavity 1300. The liquid storage cavity 1100 is used to receive purified water from the water purifier 200, and the purified water is stored in the liquid storage cavity 1100 for being supplied to the ice making cavity 1200 for ice making operation at any time. Referring to Fig. 4, an ice making module 1210 is arranged in the ice making cavity 1200. After the ice making cavity 1200 makes ice cubes C using water from the liquid storage cavity 1100, the ice cubes C are transferred from the ice making cavity 1200 to the ice storage cavity 1300, and the user can take out the ice cubes C from the ice storage cavity 1300 according to needs.

[0055] Referring to Fig. 5, when the ice cubes C exist in the ice storage cavity 1300, the ice cubes C can be taken out by using an ice taking module 1310 in the ice maker 100, i.e. the ice cubes C in the ice storage cavity 1300 are moved towards the removal port 1302, so that a desired number of ice cubes C are removed from the removal port 1302 for being taken out by the user. The ice taking module 1310 is arranged in the main body 1000. The ice taking module 1310 can be realized by using several different mechanical or electric control structures, such as manual control, motor control, telescopic mechanism, connecting rod mechanism, screw mechanism, etc. The skilled person in the art can select a suitable way according to actual needs, which is not limited herein.

[0056] At least one of the ice-making cavity 1200 and the ice storage cavity 1300 can be provided with at least one flow guide hole configured to guide liquid to the liquid storage cavity 1100. The flow guide hole provided in the ice-making cavity 1200 can be referred to as a first flow guide hole 1201, and the flow guide hole provided in the ice storage cavity 1300 can be referred to as a second flow guide hole 1301. As shown in FIGS. 8 to 10, in one embodiment, the ice-making cavity 1200 is provided with at least one first flow guide hole 1201 configured to communicate the liquid storage cavity 1100 and the ice-making cavity 1200. The ice storage cavity 1300 is provided with at least one second flow guide hole 1301 configured to communicate the liquid storage cavity 1100 and the ice storage cavity 1300.

[0057] Based on the design of the flow guide hole (the first flow guide hole 1201 or the second flow guide hole 1301), if there is residual water during ice making, or if the ice cubes C are not removed in time for use, the ice cubes C can melt and produce melted water, or if there is unused water in the ice-making cavity 1200 or the ice storage cavity 1300 due to other reasons, the water can flow back to the liquid storage cavity 1100 through the first flow guide hole 1201 of the ice-making cavity 1200 or the second flow guide hole 1301 of the ice storage cavity 1300, thereby avoiding water accumulation in the ice-making cavity 1200 or the ice storage cavity 1300.

[0058] For example, the ice-making module 1210 in the ice-making cavity 1200 can not completely use the purified water 1101 supplied from the liquid storage cavity 1100 in real time during ice making, so that the ice-making module 1210 can have some water left during ice making, or the ice-making module 1210 can not be able to transfer the ice cubes C to the ice storage cavity 1300 in time due to equipment failure or other factors, so that the ice cubes C can melt and produce melted water in the ice-making cavity 1200, and so on. Once water accumulates in the ice-making cavity 1200, it can flow back to the liquid storage cavity 1100 through the first flow guide hole 1201 of the ice-making cavity 1200, thereby avoiding water accumulation in the ice-making cavity 1200.

[0059] Similarly, if the ice cubes C in the ice storage cavity 1300 are not removed in time, or the ice cubes C are not removed in time due to equipment failure or other factors, the water melted from the ice cubes C can also flow back to the liquid storage cavity 1100 through the second flow guide hole 1301. In summary, the design of the first flow guide hole 1201 or the second flow guide hole 1301 can ensure that the ice cubes C in the ice-making cavity 1200 or the ice storage cavity 1300 will not produce water accumulation in the cavity after melting.

[0060] When the ice cubes C in the ice making cavity 1200 or the ice storage cavity 1300 melt, the melted water can be actively drained back to the liquid storage cavity 1100 based on gravity. For example, in one embodiment, the liquid storage cavity 1100 is located below the ice making cavity 1200, and the at least one first drain hole 1201 is located at the lowest position in the cavity of the ice making cavity 1200. The liquid storage cavity 1100 is located below the ice storage cavity 1300, and the at least one second drain hole 1301 is located at the lowest position in the cavity of the ice storage cavity 1300. Alternatively, the melted water can also be passively drained back to the liquid storage cavity 1100 based on a water pump or other devices, which is not limited herein. In addition, the liquid storage cavity 1100 can also be designed with a drain hole, which can facilitate the drainage of residual water in the liquid storage cavity 1100 and other places when not used for a long time, preventing the growth of bacteria and other health problems.

[0061] Referring to FIGS. 8 to 10, the ice maker 100 can further include a liquid level detection device 2000. If the defined liquid storage cavity 1100 includes the liquid storage space 1110 and the chemical liquid space 1120 connected thereto, the liquid level detection device 2000 can be configured to be disposed in the liquid storage space 1110 of the liquid storage cavity 1100, rather than being disposed in the chemical liquid space 1120 of the liquid storage cavity 1100, so that the liquid level detection device 2000 can be configured to detect the amount of liquid in the liquid storage space 1110. Regarding the division of the liquid storage space 1110 and the chemical liquid space 1120 in the liquid storage cavity 1100, the liquid storage space 1110 and the chemical liquid space 1120 can be clearly separated by a physical separation structure, for example, a partition plate or the like, to separate the liquid storage space 1110 and the chemical liquid space 1120 in the liquid storage cavity 1100, so that the liquid storage space 1110 and the chemical liquid space 1120 are two chambers connected to each other. Alternatively, the liquid storage space 1110 and the chemical liquid space 1120 can also be a part of the space in the liquid storage cavity 1100, and not be clearly separated by a physical separation structure, for example, the chemical liquid space 1120 is located above the liquid storage space 1110, so that the liquid storage space 1110 and the chemical liquid space 1120 are divided in the upper and lower space positions of the liquid storage cavity 1100.

[0062] Referring to FIG. 8, the division of the liquid storage space 1110 and the chemical liquid space 1120 in the liquid storage cavity 1100 is complementary to the liquid level detection device 2000, that is, when the liquid level detection device 2000 is disposed in the liquid storage cavity 1100, the horizontal plane at a certain device position of the liquid level detection device 2000 (assuming that the multifunctional purifier is in a horizontally placed state) can be used as a virtual separation layer 1102 to divide the liquid storage cavity 1100 into the liquid storage space 1110 and the chemical liquid space 1120. The virtual separation layer 1102 does not exist, but based on the existence of the liquid level detection device 2000, the division state of the liquid storage space 1110 and the chemical liquid space 1120 in the liquid storage cavity 1100 can be determined.

[0063] For example, the certain position of the liquid level detecting device 2000 mentioned above can be the highest liquid level detecting position of the liquid level detecting device 2000. When the liquid level detecting device 2000 detects the liquid amount in the liquid storage cavity 1100 based on the highest liquid level detecting position of the liquid level detecting device 2000, the detected result is the maximum liquid amount in the liquid storage cavity 1100. Therefore, the liquid level detecting device 2000 determines the virtual horizontal plane dividing the liquid storage space 1110 and the chemical liquid space 1120 based on the highest liquid level detecting position thereof, and the division of the liquid storage space 1110 and the chemical liquid space 1120 in the liquid storage cavity 1100 reversely determines that the liquid level detecting device 2000 is located in the liquid storage space 1110 of the liquid storage cavity 1100 rather than being arranged in the chemical liquid space 1120. Therefore, in the embodiment shown in FIG. 8, the division of the liquid storage space 1110 and the chemical liquid space 1120 in the liquid storage cavity 1100 and the liquid level detecting device 2000 complement each other.

[0064] The liquid level detecting device 2000 can include a first detecting part, which can be arranged at the highest liquid level detecting position of the liquid level detecting device 2000, so that the first detecting part can be configured to detect the highest liquid level of the liquid amount, i.e. the maximum liquid amount. When the liquid storage space 1110 and the chemical liquid space 1120 are separated by the separation layer 1102, the first detecting part can be located in the separation layer 1102 between the liquid storage space 1110 and the chemical liquid space 1120. In addition, the liquid level detecting device 2000 can further include a second detecting part, the height of the second detecting part in the liquid storage space 1110 is lower than the height of the first detecting part in the liquid storage space 1110, for example, the second detecting part can be arranged at the lowest liquid level detecting position of the liquid level detecting device 2000, so that the second detecting part can be configured to detect the lowest liquid level of the liquid amount, i.e. the minimum liquid amount.

[0065] The first detecting part and the second detecting part can be implemented in various ways to detect the maximum liquid amount and the minimum liquid amount, for example, at least one of the first detecting part and the second detecting part can be configured as a water level detecting electrode. Alternatively, at least one of the first detecting part and the second detecting part can also be configured as a reed switch.

[0066] When configured as a reed switch, the liquid level detecting device 2000 further includes a limiting rod 2100 and at least one float 2200 cooperating with the limiting rod 2100, the first detecting part and the second detecting part configured as the reed switch correspond to different heights of the limiting rod 2100, and the reed switch can be arranged inside or outside the limiting rod 2100 in the liquid storage cavity, or can be arranged at other positions of the ice maker. The float 2200 is movably arranged on the limiting rod 2100, the float 2200 can float on the water surface and float up and down along the limiting rod 2100 with the change of the water level, and in the process of floating up and down, the float 2200 can be detected by different reed switches at different water level heights.

[0067] For example, in one embodiment, the first detecting portion and the second detecting portion can both be configured as water level detecting electrodes, and the water level detecting electrodes at different height positions are used to detect the highest storage water level and the lowest storage water level. For another example, the first detecting portion and the second detecting portion can both be configured as dry reed tubes, and the float 2200 is movably installed on the limiting rod 2100, and the float 2200 floats up and down with the water level, so that the float 2200 is detected by the dry reed tube when the float 2200 is at different height positions of the water level, thereby the highest storage water level and the lowest storage water level can be detected.

[0068] In the above embodiment, the limiting rod 2100 can be provided with a stopper for limiting the movement range of the float 2200 on the limiting rod 2100, and the number of the float 2200 can be two, and the two floats 2200 are respectively used for detecting the dry reed tube at different height positions, and the movement range of the two floats 2200 on the limiting rod 2100 can be respectively limited. In addition, one of the first detecting portion and the second detecting portion can adopt the water level detecting electrode, and the other one can adopt the cooperation of the float 2200 and the dry reed tube, and those skilled in the art can select the appropriate combination according to the actual needs, or other water level detecting mechanisms or devices can be adopted, which are not limited herein.

[0069] Based on the design of the flow guide hole (the first flow guide hole 1201 or the second flow guide hole 1301), the water can flow back to the storage liquid cavity 1100 along the first flow guide hole 1201 of the ice making cavity 1200 or the second flow guide hole 1301 of the ice storage cavity 1300. Therefore, the part of the water flowing back to the storage liquid cavity 1100 can be stored by using the chemical liquid space 1120. It should be noted that the storage liquid cavity 1100 needs to receive the purified water 1101 from the purifier, and if the storage liquid cavity 1100 is full of water, the storage liquid cavity 1100 cannot receive the water flowing back from the ice making cavity 1200 or the ice storage cavity 1300. In order to solve the problem of receiving the backflow water, the storage liquid cavity 1100 is divided into the storage liquid space 1110 and the chemical liquid space 1120, the storage liquid space 1110 is mainly used to receive and store the purified water 1101 from the purifier, and the chemical liquid space 1120 is mainly used to receive and store the water flowing back from the ice making cavity 1200 or the ice storage cavity 1300. Therefore, even if the storage liquid space 1110 reaches the maximum storage capacity, it does not affect the storage liquid cavity 1100 to receive the water flowing back from the ice making cavity 1200 or the ice storage cavity 1300, that is, the chemical liquid space 1120 is used to receive the water flowing back from the ice making cavity 1200 or the ice storage cavity 1300.

[0070] The space volume of the chemical solution space 1120 can be set as needed, rather than arbitrarily, based on the amount of water that the chemical solution space 1120 needs to receive from the backflow. Since the main purpose of the chemical solution space 1120 is to receive water backflowing from the ice making cavity 1200 or the ice storage cavity 1300, the space volume of the chemical solution space 1120 can be designed based on the space volume of the ice making cavity 1200 or the ice storage cavity 1300.

[0071] For example, water can remain in the ice making cavity 1200 or the ice storage cavity 1300 after ice making, or the ice cubes C can melt when not taken out in time, and the melted water can be part of the water in the ice making cavity 1200 or the ice storage cavity 1300. Therefore, the space volume of the chemical solution space 1120 can be set based on part of the space volume of the ice making cavity 1200 or the ice storage cavity 1300.

[0072] In one embodiment, the space volume of the chemical solution space 1120 can be set to be greater than or equal to 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, etc. of the space volume of the ice making cavity 1200. Alternatively, the space volume of the chemical solution space 1120 can be set to be greater than or equal to 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, etc. of the space volume of the ice storage cavity 1300. Alternatively, the space volume of the chemical solution space 1120 can be set to be greater than or equal to the space volume of the ice making cavity 1200. Alternatively, the space volume of the chemical solution space 1120 can be set to be greater than or equal to the space volume of the ice storage cavity 1300. In this case, the space volume of the chemical solution space 1120 is based on the space volume of the ice making cavity 1200 or the ice storage cavity 1300 alone, indicating that the chemical solution space 1120 can be designed to receive water backflowing from the ice making cavity 1200 or the ice storage cavity 1300 alone.

[0073] In addition, the space volume of the chemical solution space 1120 can also be based on the sum of the space volumes of the ice making cavity 1200 and the ice storage cavity 1300, indicating that the chemical solution space 1120 can be designed to have enough space to receive water backflowing from the ice making cavity 1200 and the ice storage cavity 1300 together. For example, the space volume of the chemical solution space 1120 can be less than or equal to the sum of the space volume of the ice making cavity 1200 and the space volume of the ice storage cavity 1300. In one embodiment, the space volume of the chemical solution space 1120 can be set to be 50% to 80% of the sum of the space volume of the ice making cavity 1200 and the space volume of the ice storage cavity 1300. When the amount of water in the chemical solution space 1120 reaches a certain amount, the water in the chemical solution space 1120 can also flow back to the ice making cavity 1200 or the ice storage cavity 1300 through the flow guide hole (the first flow guide hole 1201 or the second flow guide hole 1301).

[0074] As can be seen from the foregoing, the water flowing back to the chemical liquid space 1120 can be the water melted from the ice cubes C. Since the ice cubes C are in the ice making cavity 1200 or the ice storage cavity 1300, the ice cubes C have certain gaps based on their fixed shapes. The space occupied by the gaps does not produce melted water, and thus the space of the gaps can be excluded. Therefore, the space volume of the chemical liquid space 1120 can also be calculated and designed based on the maximum ice storage volume of the ice cubes C in the ice making cavity 1200 and the ice storage cavity 1300.

[0075] According to the calculation theory described above, first, the ice making cavity 1200 can be limited to have a first maximum ice storage volume, and the space volume of the chemical liquid space 1120 can be greater than or equal to 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, etc. of the first maximum ice storage volume. Alternatively, the ice storage cavity 1300 can be limited to have a second maximum ice storage volume, and the space volume of the chemical liquid space 1120 can be greater than or equal to 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, etc. of the second maximum ice storage volume.

[0076] Even the space volume of the chemical liquid space 1120 can be limited to be greater than or equal to the first maximum ice storage volume. Alternatively, the space volume of the chemical liquid space 1120 can be greater than or equal to the second maximum ice storage volume. At this time, the space volume of the chemical liquid space 1120 is only based on the maximum ice storage volume of the ice making cavity 1200 or the ice storage cavity 1300 as a separate reference, indicating that the chemical liquid space 1120 can only be designed to receive water flowing back from the ice making cavity 1200 or the ice storage cavity 1300. In addition, the space volume of the chemical liquid space 1120 can also be based on the sum of the maximum ice storage volumes of the ice making cavity 1200 and the ice storage cavity 1300 as a reference, indicating that the chemical liquid space 1120 can be designed to have enough space to receive water flowing back from the ice making cavity 1200 and the ice storage cavity 1300 together. For example, the space volume of the chemical liquid space 1120 can be less than or equal to the sum of the first maximum ice storage volume and the second maximum ice storage volume. Those skilled in the art can design according to actual needs, which is not limited here.

[0077] Continuing to refer to FIG. 3 and FIG. 4, at least one of the ice making cavity 1200 and the ice storage cavity 1300 is provided with at least one photoelectric sensor 3000 configured to detect ice storage data of at least one of the ice making cavity 1200 and the ice storage cavity 1300. For example, the photoelectric sensor 3000 can be provided in the ice making cavity 1200 to detect ice storage data in the ice making cavity 1200, and the photoelectric sensor 3000 can also be provided in the ice storage cavity 1300 to detect ice storage data in the ice storage cavity 1300. The ice storage data is the amount of stored ice cubes C (which can be represented by height). The photoelectric sensor can be a reflection type sensor, such as a reflection type infrared sensor, without limitation.

[0078] Since the ice making cavity 1200 and the ice storage cavity 1300 are in communication, the ice cubes C generated in the ice making cavity 1200 will be transferred from the ice making cavity 1200 to the ice storage cavity 1300. Therefore, the ice making cavity 1200 and the ice storage cavity 1300 can be provided with a common photoelectric sensor 3000. The photoelectric sensor 3000 can detect the amount of ice cubes C produced in the ice making cavity 1200 and the ice storage cavity 1300 in real time, and when the amount of ice cubes C reaches a preset set amount, the photoelectric sensor 3000 can make a judgment, for example, send a prompt signal, indicating that the current amount of ice cubes C has reached the set amount.

[0079] At least one of the ice making module 1210 and the ice taking module 1310 can be connected to a control device, and the control device is in data connection with the photoelectric sensor 3000. Therefore, based on the ice storage data obtained by the photoelectric sensor 3000, the control device can be configured to control at least one of the ice making module 1210 and the ice taking module 1310 according to the ice storage data. For example, when the ice storage data indicates that the amount of ice cubes C reaches the preset amount, the control device can actively control the ice making module 1210 to stop ice making, or control the ice taking module 1310 to immediately take ice, so as to avoid the amount of ice cubes C reaching the maximum ice storage volume in the ice making cavity 1200 and the ice storage cavity 1300, and to avoid damaging the equipment and ensuring the safety of use.

[0080] In an embodiment of the present application, the ice making module 1210 can include an ice making device 1211, a liquid containing tool 1212, and an ice pushing element 1213. The liquid containing tool 1212 has a liquid containing groove configured to contain liquid from the liquid storage cavity 1100, the ice making device 1211 is configured to generate ice cubes C using the liquid in the liquid containing groove, and the ice pushing element 1213 is configured to transfer the ice cubes C generated by the ice making device 1211 to the ice storage cavity 1300.

[0081] In the above embodiment of the ice making module 1210, the water in the ice making cavity 1200 mainly comes from the liquid containing groove of the liquid containing device 1212, the water remaining from the ice making process, or the water from the melting of the ice cubes C when the ice cubes C are not taken out in time for use, all mainly come from the liquid containing groove of the liquid containing device 1212, and the capacity of the liquid containing groove of the liquid containing device 1212 is the upper limit. Therefore, the space volume of the liquid dissolving space 1120 can also be changed from referring to the space volume of the ice making cavity 1200 to referring to the capacity of the liquid containing groove.

[0082] For example, the space volume of the liquid dissolving space 1120 can be limited to be greater than or equal to 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, etc. of the capacity of the liquid containing groove. Even the space volume of the liquid dissolving space 1120 can be limited to be greater than or equal to the capacity of the liquid containing groove. Alternatively, the space volume of the liquid dissolving space 1120 can be less than or equal to the sum of the capacity of the liquid containing groove and the space volume of the ice storing cavity 1300. In one embodiment, the space volume of the liquid dissolving space 1120 can be set to be 50% to 80% of the sum of the capacity of the liquid containing groove and the space volume of the ice storing cavity 1300.

[0083] Based on the fixed shape of the ice cubes C, there must be some gaps among the ice cubes C in the ice making cavity 1200 or the ice storing cavity 1300, and the space occupied by these gaps will not produce melted water, so these gap spaces can be excluded. Therefore, the capacity of the liquid containing groove can also be limited to have the above first maximum ice storing volume. Those skilled in the art can design according to actual needs, which is not limited here.

[0084] Continuing to refer to FIGS. 8 to 10, the liquid containing device 1212 is movably assembled in the ice making cavity 1200, which can be moving, rotating, swinging, etc. Therefore, based on the movable assembly of the liquid containing device 1212 relative to the ice making cavity 1200, when the spatial position of the liquid containing device 1212 in the ice making cavity 1200 changes, the gravity ice falling direction of the ice making device 1211 can be shielded or avoided based on the different spatial positions.

[0085] It is to be noted that after the ice making device 1211 finishes making ice cubes C, the ice cubes C will fall away from the ice making device 1211 based on gravity, so that the ice making device 1211 can continue to make the next batch of ice cubes C after making a batch of ice cubes C. Therefore, the gravity ice falling direction mentioned above also refers to the direction in which the ice cubes C fall, i.e., the direction in which the ice making device 1211 faces downward. When the liquid containing device 1212 blocks the gravity ice falling direction of the ice making device 1211, the ice making device 1211 is located below the ice making device 1211, and the ice making device 1211 can use the water in the ice making device 1211 to make ice cubes C. For example, when the liquid containing device 1212 is located below the ice making device 1211, at least a part of the device structure of the ice making device 1211 is located in the ice making device 1211, and can contact the water in the ice making device 1211 to cool the water in the ice making device 1211 to make ice.

[0086] When the ice making device 1211 finishes making a batch of ice cubes C, the liquid containing device 1212 can be moved to change the spatial position, from blocking the gravity ice falling direction of the ice making device 1211 to avoiding the gravity ice falling direction of the ice making device 1211. At this time, the ice making device 1211 is not located below the ice making device 1211, and the ice cubes C made by the ice making device 1211 can fall away from the ice making device 1211 based on gravity, and fall into the ice making cavity 1200, i.e., below the liquid containing device 1212 in FIG. 8. When making the next batch of ice cubes C, the liquid containing device 1212 can continue to move back to be located below the ice making device 1211. The reciprocating operation can continuously make a batch of ice cubes C.

[0087] The ice pushing element 1213 is connected to the liquid containing device 1212, and the ice pushing element 1213 is configured to move synchronously with the liquid containing device 1212. Therefore, when the liquid containing device 1212 moves to block the gravity ice falling direction of the ice making device 1211, the ice pushing element 1213 is located at a spatial position, and when the liquid containing device 1212 moves to avoid the gravity ice falling direction of the ice making device 1211, the ice pushing element 1213 is located at another spatial position. With the reciprocating movement of the liquid containing device 1212, the ice pushing element 1213 also reciprocates between the two different spatial positions, which can make the ice pushing element 1213 generate a pushing force on the ice cubes C during the movement, thereby transferring the ice cubes C generated by the ice making device 1211 to the ice storage cavity 1300.

[0088] In one embodiment, the liquid containing device 1212 can be rotatably assembled in the ice making cavity 1200, and the liquid containing device 1212 can be configured to rotate around the ice making device 1211. For example, when the liquid containing device 1212 blocks the gravity ice falling direction of the ice making device 1211, the ice making device 1211 is located below the ice making device 1211, and the ice making device 1211 can use the water in the ice making device 1211 to make ice cubes C.

[0089] When the ice making device 1211 finishes making a batch of ice cubes C, the liquid containing device 1212 can be moved to change the spatial position, and rotated to any position such as the left side, the right side or the upper side of the ice making device 1211, so as to change the direction of gravity ice falling of the ice making device 1211 from being blocked to being avoided. At this time, the ice containing groove of the liquid containing device 1212 is not located below the ice making device 1211, and the ice cubes C made by the ice making device 1211 can fall based on gravity, and then leave the ice making device 1211 and fall into the ice making cavity 1200, that is, below the liquid containing device 1212 as shown in FIG. 8. When making the next batch of ice cubes C, the liquid containing device 1212 can continue to rotate back to be located below the ice making device 1211. The reciprocating operation can continuously make a batch of ice cubes C.

[0090] The ice pushing element 1213 is hinged with the liquid containing device 1212, so that when the liquid containing device 1212 moves to block the direction of gravity ice falling of the ice making device 1211, the ice pushing element 1213 is located at a spatial position, such as the position shown in FIG. 8, and when the liquid containing device 1212 moves to avoid the direction of gravity ice falling of the ice making device 1211, the ice pushing element 1213 is located at another spatial position. With the reciprocating movement of the liquid containing device 1212, the ice pushing element 1213 also reciprocates between the two different spatial positions, which can be referred to as the left-right direction as shown in FIG. 8. Therefore, when the ice pushing element 1213 is controlled to reciprocate in the left-right direction as shown in FIG. 8, the ice pushing element 1213 can generate a pushing force on the ice cubes C during the movement, thereby pushing the ice cubes C falling from the ice making device 1211 to the ice storage cavity 1300.

[0091] In addition, the ice making module 1210 can further include an identification sensor device 1214 configured to identify the state information of the liquid containing device 1212, and the state information includes whether the liquid containing device 1212 is in a state of blocking the direction of gravity ice falling of the ice making device 1211. Since the liquid containing device 1212 blocks the direction of gravity ice falling of the ice making device 1211 when it is in the ice making state, the state of the liquid containing device 1212 blocking the direction of gravity ice falling of the ice making device 1211 can be defined as the ice making state. When the liquid containing device 1212 does not block the direction of gravity ice falling of the ice making device 1211, it is not in the ice making state, so the state of the liquid containing device 1212 not blocking the direction of gravity ice falling of the ice making device 1211 can be defined as the ice falling state.

[0092] Therefore, the control device can be configured to control the ice making device 1211 according to the state information (the ice making state or the ice falling state), start the ice making device 1211 in the ice making state, and stop the ice making device 1211 in the ice falling state, so as to flexibly start and stop the ice making device 1211 and avoid energy waste.

[0093] In one embodiment of the present application, the ice taking module 1310 can include a driving element 1311, a transmission assembly 1312, and an ice taking element 1313, the driving element 1311 is drivingly connected with the ice taking element 1313 through the transmission assembly 1312, that is, the driving force provided by the driving element 1311 is not directly transmitted to the ice taking element 1313, but is indirectly transmitted to the ice taking element 1313 after being turned by the transmission assembly 1312. At this time, in addition to the basic role of driving force transmission, the function of the transmission assembly 1312 also includes turning the driving force of the driving element 1311, so that the driving force applied by the driving element 1311 in the first direction A can be transmitted after being turned by the transmission assembly 1312, and then applied to the ice taking element 1313 in the second direction B, thereby realizing the turning of the driving force transmission.

[0094] Referring to FIG. 5, for example, the driving element 1311 is configured to apply a driving force to the transmission assembly 1312 in the first direction A, the transmission assembly 1312 is configured to transmit the driving force to the ice taking element 1313 in the second direction B, the driving force is configured to drive the ice taking element 1313 to rotate about an axis, the first direction A and the second direction B are configured to be in different directions, thereby realizing the turning of the driving force transmission. Referring to the directions indicated by the two dashed lines shown in FIG. 5, the first direction A and the second direction B have a turning angle therebetween, the angle of the turning angle can be between 92° and 120°, for example, the angle of the turning angle can be set to 92°, 96°, 98°, 102°, 106°, 110°, 112°, 116°, 110°, 120°, etc. without limitation here.

[0095] As can be seen from the above, the driving force applied by the driving element 1311 in the first direction A can be applied to the ice taking element 1313 in the second direction B based on the transmission assembly 1312, so that the driving force is turned from the first direction A to the second direction B under the action of the transmission assembly 1312. Therefore, when the driving element 1311 and the ice taking element 1313 are assembled and designed on the ice maker 100 (mainly on the main body 1000), although the driving element 1311 and the ice taking element 1313 need to be coordinated with each other, the best direction or position of each can be selected based on the design requirements of the driving element 1311 and the ice taking element 1313, respectively, without abandoning the best design direction or position of the driving element 1311 due to the design requirements of the ice taking element 1313, and similarly, without abandoning the best design direction or position of the ice taking element 1313 due to the design requirements of the driving element 1311.

[0096] Referring to FIG. 5, for example, in the design of the ice maker 100, the ice taking element 1313 needs to be designed laterally, so that the ice cubes C are discharged from the side of the ice maker 100, which is more in line with the use habits of the user and provides a good experience. If the driving element 1311 is also designed on the side of the ice maker 100, the position of the driving element 1311 will be lower, which will cause the user to bend down to operate, resulting in a poor user experience. However, due to the presence of the transmission assembly 1312, the driving element 1311 can be arranged on the top of the ice maker 100, and does not have to be arranged on the side of the ice maker 100 to accommodate the design of the ice taking element 1313. The design on the top of the ice maker 100 is in line with the operation habits of the user and does not require the user to bend down to operate, which provides a better user experience.

[0097] In addition, the first direction A and the second direction B can be any two directions on the ice maker 100, and the matching direction and angle of the first direction A and the second direction B can be constructed according to the structural design characteristics of different types of ice makers 100, so as to achieve the best design of the ice maker 100.

[0098] When the driving force is transmitted from the driving element 1311 to the ice taking element 1313, the ice taking element 1313 can perform a predetermined ice taking action under the action of the driving force, such as pushing the ice cubes C to take ice, clamping the ice cubes C to take ice, etc. The ice taking action of the ice taking element 1313 can be determined according to the structure design of the ice taking element 1313 and the power driving of the driving element 1311, etc., which is not limited herein.

[0099] In one embodiment, at least a part of the element structure of the ice taking element 1313 can be configured as a spiral structure, for example, in one embodiment, at least a part of the element structure or the whole element structure of the ice taking element 1313 can be configured as a spiral coil and a spiral paddle, etc. Based on the spiral shape structure design, the ice cubes C can be contained in the spiral shape space, so that when the ice taking element 1313 rotates around the axis, the ice taking element 1313 can push the ice cubes C to move based on the spiral design. Since the spiral structure can rotate around a central axis (such as the B(X) axis shown in FIG. 5), the spiral structure can be used to rotate and push the ice cubes C (i.e. the target body) to move along the ice moving track during the rotation around the axis.

[0100] The ice-removing trajectory is a virtual trajectory, which represents the trajectory of the ice block C moving towards the ice-removing outlet 1302 under the driving action of the ice-taking module 1310. The ice-removing trajectory depends on the structural design of the ice-taking module 1310 and the structural design of the bottom of the ice storage cavity 1300. For example, in one embodiment, at least a portion of the bottom of the ice storage cavity 1300 can be configured as an inclined bottom surface 1304, and the entire bottom of the ice storage cavity 1300 can be configured as the inclined bottom surface 1304. The inclined bottom surface 1304 can be inclined along a straight line or a designed curve.

[0101] In one embodiment, the inclined bottom surface 1304 of the ice storage cavity 1300 is configured to be inclined along a straight line trajectory, and the ice-removing trajectory is configured as a straight line trajectory. The ice-removing trajectory is parallel to the inclined bottom surface 1304, so that the ice-removing trajectory matches the inclined bottom surface 1304 of the ice storage cavity 1300 and moves along a straight line towards the ice-removing outlet 1302. Referring to the B(X) axis shown in FIG. 5, in the embodiment shown in FIG. 5, the ice-removing trajectory can coincide with the B(X) axis. Moreover, the ice-removing outlet 1302 can be arranged at any position of the ice storage cavity 1300, such as a position in the central region of the ice storage cavity 1300, or the ice-removing outlet 1302 of the ice storage cavity 1300 can be arranged at the highest position of the inclined bottom surface 1304. Those skilled in the art can design according to actual needs, which is not limited herein.

[0102] As a component for realizing the transmission of the driving force, the transmission assembly 1312 can select various mechanisms. For example, the transmission assembly 1312 can be configured as a gear set, which can include two or more gears. For example, in one embodiment, the transmission assembly 1312 includes at least an input gear 1312a and an output gear 1312b. At this time, the transmission assembly 1312 can include only the input gear 1312a and the output gear 1312b. Alternatively, the input gear 1312a and the output gear 1312b can be indirectly drivingly engaged through at least one intermediate gear. At this time, the transmission assembly 1312 can include the input gear 1312a, the output gear 1312b, and at least one intermediate gear between them.

[0103] Moreover, at least one of the input gear 1312a and the output gear 1312b can be configured as a bevel gear, for example, the input gear 1312a or the output gear 1312b is configured as a bevel gear, the steering of the driving force transmission of a certain angle can be achieved by the gear taper of the input gear 1312a, if the input gear 1312a and the output gear 1312b are configured as bevel gears at the same time, the steering of the driving force transmission of a certain angle can also be achieved by the gear taper of the input gear 1312a and the output gear 1312b cooperating with each other. The gear taper of the bevel gear can be designed according to the steering angle of the driving force transmission, and the person skilled in the art can design according to the needs, which is not limited here.

[0104] Based on the above transmission assembly 1312, the driving element 1311 can be drivingly connected with the input gear 1312a, and the driving element 1311 can be configured to drive the input gear 1312a to rotate along the first axis, the first axis is defined as extending along the first direction A, and the first axis can refer to the A(Y) axis in FIG. 5. The input gear 1312a can be configured to directly drive the output gear 1312b to rotate along the second axis, or the input gear 1312a can also be configured to indirectly drive the output gear 1312b to rotate along the second axis through at least one intermediate gear, the second axis is defined as extending along the second direction B, and the second axis can refer to the B(X) axis in FIG. 5.

[0105] The driving element 1311 can be electrically driven by a motor or the like, or the driving element 1311 can also be a manual knob, which is fixedly rotatable with the main body 1000. In one embodiment, when the driving element 1311 is a manual knob, it can be elastically connected with the transmission assembly 1312, for example, the driving element 1311 is elastically connected with the input gear 1312a of the transmission assembly 1312. When the manually controlled driving element 1311 applies a driving force to the transmission assembly 1312, based on the elastic connection design between the driving element 1311 and the transmission assembly 1312, an opposite elastic force can be applied to the user's hand in the opposite direction, which can generate a rotating hand feeling when the driving element 1311 is rotated.

[0106] In one of the embodiments, the driving element 1311 can be elastically connected with the input gear 1312a through the elastic element 1312c. For example, referring to FIG. 6, the elastic element 1312c can be a knob spring, which is arranged between the manual knob and the input gear 1312a. In addition, the driving element 1311 can be provided with a knob gear ring 1312d, which is arranged on the input gear 1312a. The driving element 1311 can be in contact with the knob gear ring 1312d of the input gear 1312a through the elastic element 1312c, so that the manual knob is not in direct contact with the knob gear ring 1312d of the input gear 1312a, but is in contact with the knob gear ring 1312d through the knob spring, and is arranged opposite to the input gear 1312a.

[0107] In addition, the elastic element 1312c can also be a spring, a snap buckle or other components with elastic function, which is connected with the input gear 1312a through other auxiliary components. The person skilled in the art can select according to the actual needs, which is not limited herein.

[0108] The manual knob can be provided with an indication design such as an indication sticker, which can be used to indicate the rotation direction of the manual knob and the movement relationship of the ice taking element 1313. For example, the manual knob can be rotated clockwise, and the manual knob can drive the input gear 1312a to rotate. The manual knob and the input gear 1312a can be fixedly connected by means of buckling, threading, bonding and the like. For example, the manual knob can be provided with a polygonal protrusion, and the input gear 1312a can be provided with a polygonal groove, such as a three-edged or four-edged, five-edged or the like. The polygonal protrusion of the manual knob and the polygonal groove of the input gear 1312a are adapted to be inserted, and after being inserted, they can be fixed by threading, so as to ensure that the manual knob and the input gear 1312a rotate synchronously.

[0109] Similarly, the ice taking element 1313 can be provided with a polygonal protrusion, and the output gear 1312b can be provided with a polygonal groove. The polygonal protrusion of the ice taking element 1313 and the polygonal groove of the output gear 1312b are adapted to be inserted, and after being inserted, they can be fixed by threading, so as to ensure that the ice taking element 1313 and the output gear 1312b rotate synchronously. The output gear 1312b can be a screw gear, and the tapered teeth of the screw gear can be engaged with the tapered teeth of the input gear 1312a. In addition, if the manual knob is limited to taking ice when it is rotated clockwise, the manual knob can also be rotated counterclockwise. When the ice block C is stuck, the manual knob can be rotated counterclockwise, so that the ice taking element 1313 is reversely rotated, and the problem of the ice block C being stuck is solved by reversing.

[0110] Continuing to refer to FIG. 8, the main body 1000 includes a first casing 1010 and a second casing 1020, the first casing 1010 is assembled inside the second casing 1020, and the first casing 1010 and the second casing 1020 can constitute the main structure of the main body 1000. The liquid storage cavity 1100, the ice making cavity 1200, and the ice storage cavity 1300 are located in the first casing 1010, and at least part of the interval gap between the first casing 1010 and the second casing 1020 is filled with thermal insulation foam. The thermal insulation foam can surround at least one of the liquid storage cavity 1100, the ice making cavity 1200, and the ice storage cavity 1300 outside, and can provide sufficient thermal insulation effect for at least one of the liquid storage cavity 1100, the ice making cavity 1200, and the ice storage cavity 1300. For example, according to the distribution or arrangement design of the liquid storage cavity 1100, the ice making cavity 1200, and the ice storage cavity 1300 inside the main body 1000, the thermal insulation foam can be arranged outside at least one of the liquid storage cavity 1100, the ice making cavity 1200, and the ice storage cavity 1300 according to the thermal insulation requirement, and the thickness of the thermal insulation foam outside any one of the liquid storage cavity 1100, the ice making cavity 1200, and the ice storage cavity 1300 can also be adjusted according to the thermal insulation requirement, which is not limited herein.

[0111] By filling the thermal insulation foam, parts can be saved, and the filling of the thermal insulation foam can be more sufficient when facing complex structures. In addition, the exterior of the first casing 1010 and the second casing 1020 can also be provided with a main body shell 1030 for structure protection, exterior design, etc. The structure design and material design of the main body 1000 can be set according to actual requirements by those skilled in the art, which is not limited herein.

[0112] Regarding the structure design of the liquid storage cavity 1100, the ice making cavity 1200, and the ice storage cavity 1300 in the first casing 1010, in one embodiment, the first casing 1010 can include an upper casing and a lower casing, and the upper casing is arranged above the lower casing. At this time, the ice making cavity 1200 and the ice storage cavity 1300 can be arranged in the upper casing, and the liquid storage cavity 1100 can be arranged in the lower casing, so that when the upper casing and the lower casing are connected, the upper casing can cover the cavity opening of the liquid storage cavity 1100 of the lower casing. In other words, when the upper casing covers the cavity opening of the liquid storage cavity 1100 of the lower casing after the upper casing and the lower casing are assembled and connected, the space of the liquid storage cavity 1100 of the lower casing can also communicate with part of the internal space of the upper casing, and then part of the internal space of the upper casing can be used to store purified water 1101.

[0113] The upper shell and the lower shell can be assembled with each other by bonding, screwing, clamping and the like, and can be sealed according to requirements. For example, in order to enable the liquid storage cavity 1100 to also utilize a part of the internal space of the upper shell, the upper shell and the lower shell can be sealed and connected, so that the upper shell can seal the cavity opening of the liquid storage cavity 1100 of the lower shell, and the liquid storage cavity 1100 and a part of the internal space of the upper shell together form a sealed through space. Therefore, when the purified water 1101 in the liquid storage cavity 1100 of the lower shell is full, a part of the internal space of the upper shell can also be used for storage of the purified water 1101.

[0114] In addition, when the liquid storage cavity 1100 and a part of the internal space of the upper shell together form a sealed through space, if the purified water in the liquid storage cavity 1100 is full, the purified water can also flow back to the ice making cavity 1200 or the ice storage cavity 1300 along the flow guide, and then flow out from the transfer outlet 1302 of the ice storage cavity 1300, so as to avoid the purified water in the liquid storage cavity 1100 overflowing into the internal space of the ice maker, causing damage to related electrical components, and ensuring the use safety of the machine.

[0115] Continuing to refer to FIG. 7, the main body 1000 is provided with an outlet blocking piece 1303, which is movably connected relative to the main body 1000. The movement can be a movement in space, or can also be a rotation and the like. Therefore, when the outlet blocking piece 1303 moves, the transfer outlet 1302 of the ice storage cavity 1300 can be opened or closed. For example, the outlet blocking piece 1303 can be a baffle, one end of the outlet blocking piece 1303 is rotatably assembled relative to the main body 1000 by a rotating shaft or the like. By rotating on the main body 1000, the transfer outlet 1302 can be blocked to close the transfer outlet 1302, or the transfer outlet 1302 can be avoided to open the transfer outlet 1302. The outlet blocking piece 1303 can be made of rubber, plastic or the like. When the ice block C is transferred to the transfer outlet 1302, the ice block C collides with the outlet blocking piece 1303, so that the outlet blocking piece 1303 rotates to open the transfer outlet 1302, and the ice block C falls from the transfer outlet 1302 and is taken out.

[0116] Continuing to refer to FIGS. 2-4, the top of the main body 1000 can be provided with a body window 1011, which is a common window of the ice making cavity 1200 and the ice storage cavity 1300, i.e., the body window 1011 simultaneously communicates the ice making cavity 1200 and the ice storage cavity 1300, and thus, a window cover plate 1012 is arranged at the body window 1011, which can simultaneously cover the ice making cavity 1200 and the ice storage cavity 1300. In one embodiment, the top surface of the main body 1000 is provided with a cover plate groove 1013 and an extension recess 1014 communicating with the cover plate groove 1013, and the window cover plate 1012 is arranged in the cover plate groove 1013, so that the window cover plate 1012 can be flush with the top surface of the main body 1000 after being embedded in the cover plate groove 1013, and the extension recess 1014 is exposed to the window cover plate 1012, and at this time, the extension recess 1014 communicating with the cover plate groove 1013 can serve as a handhold, facilitating the fingers to extend into the extension recess 1014 to open the window cover plate 1012.

[0117] The body window 1011 can also be provided with an outer decorative cover plate 1015 located outside the window cover plate 1012. The outer decorative cover plate 1015 can be directly held and lifted without the aid of tools, and the inner surface and the outer surface of the cover body of the outer decorative cover plate 1015 are not designed with structures, which facilitates cleaning and is aesthetically pleasing when opened. After the outer decorative cover plate 1015 is opened, the window cover plate 1012 can be directly seen, and the opening and lifting of the outer decorative cover plate 1015 and the window cover plate 1012 can facilitate cleaning of the ice making cavity 1200 and the ice storage cavity 1300 inside, and when not in use, the ice making module 1210 and the ice taking module 1310 can be conveniently cleaned.

[0118] Referring to FIG. 11, the ice maker 100 can further include a liquid taking assembly 4000 for taking water from the water tank of the water purifier 200 and transporting the water to the liquid storage cavity 1100 of the ice maker 100. The liquid taking assembly 4000 can include a liquid taking pipeline 4100, a liquid taking valve 4200 and a liquid taking pump 4300, the liquid taking pipeline 4100 is configured to connect the liquid storage cavity 1100 and the cooperating water purifier 200, the liquid taking valve 4200 is arranged in the liquid taking pipeline 4100 for passing through or blocking the liquid taking pipeline 4100, and the liquid taking pump 4300 is arranged in the liquid taking pipeline 4100 for driving the liquid to enter the liquid storage cavity 1100 of the main body 1000 along the liquid taking pipeline 4100.

[0119] When the purified water 1101 in the storage cavity 1100 does not reach the predetermined high water level, the water taking pump 4300 can continuously work to continuously draw water from the water purifier tank of the water purifier 200 to the storage cavity 1100 of the ice maker 100. The water taking valve 4200 can be any valve body capable of controlling the opening and closing of the pipeline, so as to control the opening or closing of the water taking pipeline 4100 as needed. For example, an electromagnetic valve can be used. Therefore, the water taking valve 4200 can block the water connection between the water purifier tank and the storage cavity as needed, so as to avoid the water in the water purifier tank and the storage cavity from flowing into each other unexpectedly after the water taking is completed.

[0120] Referring to FIG. 11, the ice maker 100 can further include a water supply assembly 5000. The water supply assembly 5000 includes a water supply pipeline 5100, a water supply valve 5200, and a water supply pump 5300. The water supply pipeline 5100 connects the storage cavity 1100 and the ice making cavity 1200. The water supply valve 5200 is arranged on the water supply pipeline 5100 and is used to selectively switch to the water supply pipeline 5100 connected to one of the two water outlet ends of the water supply valve 5200 or an ice water outlet connected to the other of the two water outlet ends as shown in FIG. 11. The water supply pump 5300 is arranged between the storage cavity 1100 and the water supply valve 5200 and is used to drive the liquid in the storage cavity 1100 to flow along the water supply pipeline 5100 into the ice making cavity 1200 or into the ice water outlet.

[0121] The water supply valve 5200 can be any valve body capable of controlling the opening and closing of the pipeline, for example, an electromagnetic valve can be used. During ice making, the water supply pump 5300 drives the water in the storage cavity to flow into the ice making cavity 1200 and fill the liquid holding groove of the liquid holding device 1212. When the purified water 1101 in the storage cavity 1100 reaches the predetermined high water level, the water supply pump 5300 can start to work to perform the ice making process. When the purified water 1101 in the storage cavity 1100 falls to the predetermined low water level, the water supply pump 5300 stops working. When the purified water 1101 in the storage cavity 1100 is between the predetermined low water level and the predetermined high water level, the water supply pump 5300 is also allowed to work to perform the ice making process.

[0122] Referring to FIGS. 12 to 16, the multifunctional water purifier according to the present application includes a water purifier 200 and an ice maker 100 which is detachably assembled to the water purifier 200. The water purifier 200 is provided with a filter module and an expansion function module 400, and the expansion function module 400 includes a host computer electrical docking element 401. The ice maker 100 is provided with an accessory computer docking module 500, and the accessory computer docking module 500 includes an accessory computer electrical docking element 501. When the ice maker 100 is assembled with the water purifier 200, the accessory computer electrical docking element 501 is docked with the host computer electrical docking element 401.

[0123] And, one of the host electrical docking element 401 and the accessory electrical docking element 501 comprises: at least two first male connectors 61 and at least one second male connector 62, the second male connector 62 comprises a first number of male conductive parts 621, and any one of the male conductive parts 621 is insulated from any other male conductive part 621, and the first number is greater than or equal to two. The other of the host electrical docking element 401 and the accessory electrical docking element 501 corresponds to comprise: at least two first female connectors 71 and at least one second female connector 72, the first female connector 71 is connected with the first male connector 61, and the second female connector 72 is connected with the second male connector 62; wherein, the second female connector 72 comprises a first number of female conductive parts 721, and any one of the female conductive parts 721 is insulated from any other female conductive part 721, and the female conductive part 721 is connected with the male conductive part 621 one by one. It should be understood that the first number is greater than or equal to two, that is, the first number can be two or three or four or five or other values.

[0124] For example, referring to FIG. 1, in some embodiments of the present application, the water purifier 200 is provided with a filter module, which is used to filter raw water to form purified water. The purified water filtered by the filter module can be directly used by the user and / or supplied to the ice maker 100. For example, as shown in FIG. 12, the water purifier 200 is provided with a water outlet nozzle 201, through which the user can receive purified water.

[0125] As shown in FIG. 1, in some embodiments of the present application, the functional water machine 130 is taken as an example of the ice maker 100. However, the present application is not limited thereto, for example, the functional water machine 130 can also be a tea maker, a tea infuser, or a coffee machine, etc. The water purifier 200 can directly deliver purified water to the ice maker 100, so that the user does not need to manually transfer the purified water made by the water purifier 200 to the ice maker 100, thereby improving the user's experience. Moreover, since the user does not need to manually transfer the purified water from the water purifier 200 to the ice maker 100, the problem of pollution of the purified water during the transfer process is avoided, thereby ensuring the cleanliness of the water.

[0126] For example, as shown in FIG. 1, FIG. 12 and FIG. 13, the extension function module 400 can include the host waterway docking element 402, and the accessory docking module 500 can include the accessory waterway docking element 502. When the water purifier 200 and the ice maker 100 are in the assembled state, the host waterway docking element 402 and the accessory waterway docking element 502 are in the docking state, so that the waterway system in the water purifier 200 is connected with the waterway system in the ice maker 100. When the waterway system in the water purifier 200 is connected with the waterway system in the ice maker 100, liquid can flow between the water purifier 200 and the ice maker 100. For example, the purified water produced by the filtering module is transported to the ice maker 100, so that the water purifier 200 provides purified water for the ice maker 100.

[0127] Of course, since the waterway system in the water purifier 200 can be connected with the waterway system in the ice maker 100, water in the ice maker 100 can also flow back to the water purifier 200 for further filtering. For example, when the purified water is stored in the ice maker 100 and is not used for a long time, the purified water stored in the ice maker 100 flows back to the water purifier 200 for further filtering.

[0128] As shown in FIG. 14 to FIG. 16, in some embodiments of the present application, the host electrical docking element 401 includes at least two first female connectors 71 and one second female connector 72, and the accessory electrical docking element 501 includes at least two first male connectors 61 and at least one second male connector 62. However, the present application is not limited thereto. For example, in another embodiment of the present application, the host electrical docking element 401 includes at least two first male connectors 61 and at least one second male connector 62, and the accessory electrical docking element 501 includes at least two first female connectors 71 and at least one second female connector 72.

[0129] As shown in FIG. 16, when the host electrical docking element 401 and the accessory electrical docking element 501 are in the docking state, the first male connector 61 and the first female connector 71 are connected one by one, and the second male connector 62 and the second female connector 72 are connected one by one. It can also be understood that when the host electrical docking element 401 and the accessory electrical docking element 501 are in the docking state, one first male connector 61 only establishes a conductive connection relationship with one first female connector 71, and one second male connector 62 only establishes a conductive connection relationship with one second female connector 72.

[0130] As shown in FIGS. 15-17, the first male connector 61 and the first female connector 71 are both single pieces, i.e., only one conductive path can be formed in the first male connector 61 when the first male connector 61 is powered. Similarly, only one conductive path can be formed in the first female connector 71 when the first female connector 71 is powered. Therefore, when the main electrical docking element 401 and the auxiliary electrical docking element 501 are in the docking state, only one conductive path can be formed between the first male connector 61 and the first female connector 71 that are in the connection relationship.

[0131] As shown in FIG. 15, in some embodiments of the present application, the auxiliary electrical docking element 501 has five first male connectors 61. As shown in FIG. 16, the main electrical docking element 401 can correspondingly have five first female connectors 71. When the main electrical docking element 401 and the auxiliary electrical docking element 501 are in the docking state, the five first female connectors 71 and the five first male connectors 61 are connected one-to-one, so that at least five conductive paths are formed between the main electrical docking element 401 and the auxiliary electrical docking element 501 that are in the docking relationship.

[0132] Among the five conductive paths formed by the five first female connectors 71 and the five first male connectors 61, one conductive path can be connected between the neutral line of the water purifier 200 and the neutral line of the ice maker 100, and another conductive path can be connected between the live line of the water purifier 200 and the live line of the ice maker 100, so that the water purifier 200 and the ice maker 100 are electrically connected.

[0133] For example, in some embodiments of the present application, the water purifier 200 is used to connect with a power source (such as a mains), so that the electrical energy output by the power source can be transmitted to the ice maker 100 through the water purifier 200, achieving the effect that the water purifier 200 and the ice maker 100 are both powered. In the use of the multifunctional water purifier, the user does not need to use a conductive wire to connect the water purifier 200 and the ice maker 100 with the power source, but only needs to connect the water purifier 200 with the power source, improving the user's experience. In addition, one conductive wire is also reduced, reducing production costs.

[0134] Since the entire multifunctional water purifier only needs to use one conductive wire to connect with the power source, the multifunctional water purifier can be applied to more environmental scenarios (for example, an environmental scenario only has one available socket). In addition, it is worth noting that among the five conductive paths formed by the five first female connectors 71 and the five first male connectors 61, still another conductive path can be connected between the ground line of the water purifier 200 and the ground line of the ice maker 100, playing a protective role for the multifunctional water purifier.

[0135] It should be further noted that the first male connector 61 is a component integrally formed of a conductive material (such as copper, silver, aluminum, etc.), so that the first male connector 61 is configured as a single piece. Therefore, the cross section (the cross section perpendicular to the central axis of the first male connector 61) of the first male connector 61 is the cross-sectional area of the conductive path formed by the first male connector 61, so that the cross-sectional area of the conductive path of the first male connector 61 is large, reducing the contact resistance and Joule heat loss. Similarly, the same is true for the first female connector 71.

[0136] In some embodiments of the present application, when the host electrical docking element 401 and the accessory electrical docking element 501 are docked, five first male connectors 61 and five first female connectors form five conductive paths capable of transmitting large current, three of which are configured as the neutral line, the live line and the ground line between the water purifier 200 and the ice maker 100. The remaining two conductive paths can also be used for electrical signal transmission between the water purifier 200 and the ice maker 100. Compared with transmitting electrical energy, the current when transmitting electrical signals is smaller, so the remaining two conductive paths have the ability to transmit electrical signals.

[0137] In addition, it should be further noted that in some embodiments of the present application, the number of first male connectors 61 is five, and the number of first female connectors 71 is five, so that five conductive paths capable of transmitting large current are formed between the water purifier 200 and the ice maker 100. However, the present application is not limited to this. In other embodiments of the present application, the number of first male connectors 61 and the number of first female connectors 71 can be only two, so that two conductive paths capable of transmitting large current are formed between the water purifier 200 and the ice maker 100, and the two conductive paths capable of transmitting large current are configured as the neutral line and the live line between the water purifier 200 and the ice maker 100, to ensure that one of the water purifier 200 and the ice maker 100 can supply power to the other for operation.

[0138] As shown in FIG. 15, in some embodiments of the present application, the accessory electrical docking element 501 includes six male connectors, including five first male connectors 61 and one second male connector 62. Correspondingly, the host electrical docking element 401 can also be provided with six female connectors, including five first female connectors 71 and one second female connector 72.

[0139] And in combination with FIG. 16 and FIG. 18, in some embodiments of the present application, the second male connector 62 includes two male conductive parts 621, and the two male conductive parts 621 are insulated from each other. The second female connector 72 can include two female conductive parts 721, and the two female conductive parts 721 are insulated from each other. Thus, when the host electrical docking element 401 and the slave electrical docking element 501 are in the docking state, the two male conductive parts 621 of the second male connector 62 are connected to the two female conductive parts 721 of the second female connector 72 one by one, so that one second female connector 72 and one first male connector 61 form two conductive paths in the connected state.

[0140] For example, the connected second female connector 72 and second male connector 62 can be used as a weak current (such as outputting five volts of electricity, twelve volts of electricity, or twenty-four volts of electricity, etc.) conductive structure between the water purifier 200 and the ice maker 100. Among them, for the two conductive paths formed by the second female connector 72 and the first male connector 61, one conductive path is used as a positive (﹢) transmission path, and the other conductive path is used as a negative (-) or ground (GND) transmission path.

[0141] In addition, the connected second female connector 72 and second male connector 62 can also be used as a conductive structure for electrical signal transmission between the water purifier 200 and the ice maker 100. For example, for the two conductive paths formed by the second female connector 72 and the first male connector 61, one conductive path is used as a signal output path, and the other conductive path is used as a signal receiving path, thereby realizing the effect of electrical signal transmission between the water purifier 200 and the ice maker 100. In this way, the water purifier 200 can control the working state of the ice maker 100, and the water purifier 200 can obtain the state information of the ice maker 100. Of course, it is also possible to realize the control of the working state of the water purifier 200 by the ice maker 100, and the ice maker 100 obtains the state information of the water purifier 200.

[0142] Therefore, in the present application, when the water purifier 200 and the ice maker 100 are assembled and matched, the conductive path composed of the first male connector 61 and the first female connector 71 meets the transmission demand of large current (and can also meet the transmission demand of small current), and the conductive path composed of the second male connector 62 and the second female connector 72 meets the transmission demand of small current.

[0143] It should be noted that, referring to FIG. 16, in some embodiments of the present application, each second female connector 72 has two female conductive parts 721, and each second male connector 62 has two male conductive parts 621, so that one second female connector 72 and one first male connector 61 form two conductive paths in the connected state. However, the present application is not limited thereto, and in other embodiments of the present application, the number of female conductive parts 721 of each second female connector 72 can be specifically set according to actual needs, and the number of male conductive parts 621 of each second male connector 62 can also be specifically set according to actual needs.

[0144] In combination with FIG. 15, in some embodiments of the present application, the host electrical connection element 401 includes five first female connectors 71 and one second female connector 72, and the second female connector 72 has two female conductive parts 721; and the accessory electrical connection element 501 is correspondingly provided with five first male connectors 61 and one second male connector 62, and the second male connector 62 has two male conductive parts 621.

[0145] In this way, when the host electrical connection element 401 and the accessory electrical connection element 501 are connected and matched, seven conductive paths are formed between the host electrical connection element 401 and the accessory electrical connection element 501. That is, even if the host electrical connection element 401 and the accessory electrical connection element 501 are each provided with only six connectors, seven conductive paths are formed between the host electrical connection element 401 and the accessory electrical connection element 501. In other words, the number of conductive paths formed between the host electrical connection element 401 and the accessory electrical connection element 501 is greater than the number of groups of connectors connected in the host electrical connection element 401 and the accessory electrical connection element 501. It should be understood that, for example, one first male connector 61 and one first female connector 71 form a group, and one second male connector and one second female connector 72 form a group.

[0146] Thus, by setting one of the host electrical docking element 401 and the accessory electrical docking element 501 with the second male connector 62, and the other of the host electrical docking element 401 and the accessory electrical docking element 501 with the second female connector 72, the number of conductive paths formed between the host electrical docking element 401 and the accessory electrical docking element 501 is greater than the number of connectors of the host electrical docking element 401 and the accessory electrical docking element 501, respectively. Therefore, when the number of connectors that can be provided in the host electrical docking element 401 and the accessory electrical docking element 501 is fixed, the number of conductive paths formed between the host electrical docking element 401 and the accessory electrical docking element 501 can meet the use requirements of the multifunctional water purifier. It needs to be supplemented that the above connector is a general term of the first female connector 71, the second female connector 72, the first male connector 61 and the second male connector 62. That is, the connector is used to refer to the first female connector 71, the second female connector 72, the first male connector 61 and the second male connector 62.

[0147] It needs to be understood that since the ice maker 100 can be an ice maker, a tea maker, a tea infuser, or a coffee machine, etc. with different functions, when the ice maker 100 with different functions is combined with the water purifier 200, the number of conductive paths required by the water purifier 200 and the ice maker 100 with different functions is not necessarily the same.

[0148] Since the second male connector 62 has at least two male conductive parts 621, and the second female connector 72 has at least two female conductive parts 721, at least two conductive paths are formed between a single set of the second male connector 62 and the second female connector 72. Of course, as the number of male conductive parts 621 in the second male connector 62 increases, and the number of female conductive parts 721 in the second female connector 72 increases, more conductive paths can be formed between a single set of the second male connector 62 and the second female connector 72. And as the number of sets of the second male connector 62 and the second female connector 72 increases, the number of conductive paths formed between the host electrical docking element 401 and the accessory electrical docking element 501 also increases.

[0149] Based on this, in the case that a limited number of connecting bodies are arranged on the host electrical docking element 401 and the accessory electrical docking element 501, the compatibility of the water purifier 200 with ice machines 100 of different functional types can be ensured, so that the water purifier 200 can be used with different ice machines 100. It should be noted that the different ice machines 100 can be devices of different functional types, such as ice makers, tea boilers, tea infusers, or coffee machines, or can be different versions of the same functional type device. In addition, it should be noted that because the water purifier 200 has high compatibility, the number of ice machines 100 included in the multifunctional water purifier can be multiple, and the functional types of the multiple ice machines 100 can be different.

[0150] It should be noted that in some cases, the host electrical docking element 401 and the accessory electrical docking element 501 have limited size and can only be arranged with a certain number of connecting bodies. Because the number of conductive paths formed between the host electrical docking element 401 and the accessory electrical docking element 501 is greater than the number of groups of connecting bodies connected in groups in the host electrical docking element 401 and the accessory electrical docking element 501. This significantly improves the electrical connection density in a limited space, so that the same water purifier 200 can be adapted to ice machines 100 of different functional types or versions. This structure effectively enhances device compatibility, expands the application scenarios of multifunctional water purifiers, and allows users to flexibly select ice machines 100 according to their needs, while ensuring the reliability and safety of electrical connections, meeting the needs of diversified use scenarios, and significantly improving user experience.

[0151] In summary, according to the multifunctional water purifier of the present application, one of the host electrical docking element 401 and the accessory electrical docking element 501 includes at least two first male connecting bodies 61 and at least one second male connecting body 62, the second male connecting body 62 includes a first number of male conductive parts 621, and any one of the male conductive parts 621 is insulated from any other male conductive part 621, and the first number is greater than or equal to two. And the other of the host electrical docking element 401 and the accessory electrical docking element 501 corresponds to at least two first female connecting bodies 71 and at least one second female connecting body 72, the first female connecting body 71 is connected to the first male connecting body 61, and the second female connecting body 72 is connected to the second male connecting body 62. Among them, the second female connecting body 72 includes a first number of female conductive parts 721, and any one of the female conductive parts 721 is insulated from any other female conductive part 721, and the female conductive part 721 is connected to the male conductive part 621 one by one.

[0152] This makes the number of conductive paths formed between the host electrical docking element 401 and the attached electrical docking element 501 greater than the number of groups of connecting bodies connected by the connecting body in the host electrical docking element 401 and the attached electrical docking element 501. Therefore, when the number of connecting bodies that can be provided in the host electrical docking element 401 and the attached electrical docking element 501 is fixed, the number of conductive paths formed between the host electrical docking element 401 and the attached electrical docking element 501 can meet the use requirements of the water purifier 200 and the ice maker 100. And this can also ensure that the water purifier 200 is compatible with different ice makers 100 (such as different functional types, different versions, etc.), so that the use scenarios that the multifunctional water purifier can be applied to are increased to meet the different use requirements of users and improve the use experience of users.

[0153] Next, please refer to FIG. 17, and FIGS. 19-21. First of all, it needs to be understood that the attached electrical docking element 501 is provided with six male connecting bodies in FIG. 17, including three first male connecting bodies 61 and three second male connecting bodies 62. The three second male connecting bodies 62 are respectively three embodiments of the second male connecting body 62, which correspond to the three second male connecting bodies 62 shown in FIGS. 19-21.

[0154] Referring to FIGS. 19 and 20, in some embodiments of the present application, from the inner core to the outer edge direction of the second male connecting body 62, the adjacent two male conductive parts 621 are layered and sleeved, and the insulating part 622 is arranged between the adjacent two male conductive parts 621. The insulating part 622 is arranged between the adjacent two male conductive parts 621 to achieve the effect of insulating the adjacent two male conductive parts 621, thereby avoiding the electrical connection of the adjacent two male conductive parts 621 and ensuring that each male conductive part 621 in the second male connecting body 62 forms an independent conductive path.

[0155] For example, in combination with FIG. 17, and FIGS. 19 and 20, in some embodiments of the present application, the main body of the second male connecting body 62 is configured as a cylinder. Therefore, from the inner core to the outer edge direction of the second male connecting body 62, it can also be understood as the direction from the center of the second male connecting body 62 to the outer contour in the radial direction of the second male connecting body 62. However, the present application is not limited thereto, and in another embodiment of the present application, the main body of the second male connecting body 62 is configured as a prism, such as a triangular prism, a quadrangular prism, or a pentagonal prism.

[0156] In some embodiments of the present application, as shown in FIG. 17, FIG. 19 and FIG. 20, the innermost male conductive part 621 in the inner core to the outer edge direction of the second male connector 62 is configured as a column, and the outer male conductive part 621 is configured as a cylinder, so that the adjacent two male conductive parts 621 are nested in layers in the inner core to the outer edge direction of the second male connector 62, so that the plurality of male conductive parts 621 form a second male connector 62 with a columnar configuration. It should be noted that in some embodiments of the present application, the innermost male conductive part 621 is configured as a column. However, the present application is not limited to this. For example, in another embodiment of the present application, the innermost male conductive part 621 can also be configured as a cylinder.

[0157] In some embodiments of the present application, as shown in FIG. 17 and FIG. 19, along the axial direction of the second male connector 62, at least one end of the inner male conductive part 621 is exposed to the outer male conductive part 621, so that each male conductive part 621 in the second male connector 62 is adapted to be connected with the corresponding female conductive part 721, realizing the formation of multiple conductive paths between the single set of second male connector 62 and second female connector 72.

[0158] For example, in an embodiment of the present application, as shown in FIG. 17 and FIG. 19, the second male connector 62 includes two male conductive parts 621 and an insulating part 622, and the two male conductive parts 621 are respectively a first male conductive part 6211 and a second male conductive part 6212. In the inner core to the outer edge direction of the second male connector 62, the first male conductive part 6211 is located inside the second male conductive part 6212. It can also be understood that the second male conductive part 6212 is nested in the first male conductive part 6211, and an insulating part 622 is further arranged between the first male conductive part 6211 and the second male conductive part 6212 to avoid electrical connection between the first male conductive part 6211 and the second male conductive part 6212.

[0159] Since the first male conductive part 6211 is configured as a solid structure, in the axial direction of the second male connector 62, both ends of the first male conductive part 6211 are exposed to the second male conductive part 6212, so that one of the two ends of the first male conductive part 6211 exposed to the second male conductive part 6212 is used for contact connection with one female conductive part 721 in the second female connector 72, and the other end of the first male conductive part 6211 exposed to the second male conductive part 6212 is used for connection with the internal circuit of the ice maker 100. The other female conductive part 721 in the second female connector 72 is in contact connection with the outer peripheral surface of the second male conductive part 6212. Thus, the second male connector 62 and the second female connector 72 are connected and matched to form two conductive paths.

[0160] It should be understood that the embodiment shown in FIG. 17 is described by taking the example of the first male connector 61 and the second male connector 62 included in the accessory electrical docking element 501, so the other of the two ends of the first male electrically-conductive portion 6211 exposed to the second male electrically-conductive portion 6212 needs to be connected to the internal circuit of the ice maker 100. If the main electrical docking element 401 includes the first male connector 61 and the second male connector 62, then the other of the two ends of the first male electrically-conductive portion 6211 exposed to the second male electrically-conductive portion 6212 needs to be connected to the internal circuit of the water purifier 200.

[0161] It should be further understood that the first male electrically-conductive portion 6211 is configured as a solid structure in the embodiment shown in FIG. 19, but the present application is not limited thereto. Referring to FIG. 19, the first male electrically-conductive portion 6211 can also be configured as a cylindrical structure, so that the first male electrically-conductive portion 6211 can only need one end exposed to the second male electrically-conductive portion 6212, i.e., the end exposed to the second male electrically-conductive portion 6212 is used for contact connection with one of the female electrically-conductive portions 721 in the second female connector 72, and the internal circuit of the ice maker 100 can be extended into the interior of the first male electrically-conductive portion 6211 to achieve the effect of connection.

[0162] Thus, as shown in FIG. 19, the second male connector 62 is configured by at least one end of the male electrically-conductive portion 621 located on the inside exposed to the male electrically-conductive portion 621 located on the outside, so that the exposed part of the male electrically-conductive portion 621 is used for contact connection with the female electrically-conductive portion 721, to ensure that each of the layered male electrically-conductive portions 621 can be connected to the corresponding female electrically-conductive portion 721 one by one, so that the second male connector 62 and the second female connector 72 constitute a plurality of electrically-conductive paths.

[0163] And in the axial direction of the second male connector 62, the contact positions of the different groups of male electrically-conductive portions 621 and female electrically-conductive portions 721 are staggered. That is, the contact positions of the plurality of groups of male electrically-conductive portions 621 and female electrically-conductive portions 721 present the effect of being arranged in sequence along the axial direction of the second male connector 62. Thus, the second male connector 62 can be adapted to the female electrically-conductive portions 721 of different lengths in the second female connector 72.

[0164] Due to the different lengths of the female conductive parts 721 in the second female connector 72, the time when each female conductive part 721 starts to contact the corresponding male conductive part 621 is different during the plugging process of the second male connector 62 and the second female connector 72. Therefore, when the plugging action of the second male connector 62 and the second female connector 72 is completed, all the corresponding male conductive parts 621 and female conductive parts 721 establish a contact connection relationship, so that all the conductive paths formed by the second male connector 62 and the second female connector 72 are completed. For example, based on the fact that all the corresponding male conductive parts 621 and female conductive parts 721 establish a contact connection relationship when the plugging action of the second male connector 62 and the second female connector 72 is completed. In this way, whether all the conductive paths formed by the second male connector 62 and the second female connector 72 are completed can be used to determine whether the main machine electrical docking element 401 of the water purifier 200 and the auxiliary machine docking module 500 of the ice maker 100 complete the plugging action.

[0165] In some embodiments of the present application, as shown in FIGS. 17 and 20, in the two adjacent male conductive parts 621, the male conductive part 621 located on the outer side is provided with a containing space 621a for containing the male conductive part 621 located on the inner side, and an insulating part 622 is arranged between the two adjacent male conductive parts 621. Moreover, the peripheral wall of the male conductive part 621 located on the outer side is provided with a connecting port 621b, and the insulating part 622 is provided with a avoiding port 6220, and the orthographic projection of the avoiding port 6220 is located in the orthographic projection of the connecting port 621b from the inner core to the outer edge direction of the second male connector 62. In this way, each male conductive part 621 in the second male connector 62 is adapted to be connected with the corresponding female conductive part 721, and multiple conductive paths are formed between the single set of second male connector 62 and second female connector 72.

[0166] For example, as shown in FIG. 20, in an embodiment of the present application, the second male connector 62 includes two male conductive parts 621 and one insulating part 622, and the two male conductive parts 621 are respectively a first male conductive part 6211 and a second male conductive part 6212. From the inner core to the outer edge direction of the second male connector 62, the first male conductive part 6211 is located on the inner side of the second male conductive part 6212, which can also be understood as that the second male conductive part 6212 is sleeved on the first male conductive part 6211, and an insulating part 622 is arranged between the first male conductive part 6211 and the second male conductive part 6212 to avoid electrical connection between the first male conductive part 6211 and the second male conductive part 6212.

[0167] The circumferential wall of the second male conductive part 6212 is provided with a connecting opening 621b, and in the direction from the inner core to the outer edge of the second male connector 62, the insulating part 622 is provided with an avoiding opening 6220, and the orthogonal projection of the avoiding opening 6220 completely coincides with the orthogonal projection of the connecting opening 621b. The avoiding opening 6220 is used to expose the first male conductive part 6211 inside the insulating part 622. In this way, in the process of plugging the second male connector 62 and the second female connector 72, the female conductive part 721 passes through the connecting opening 621b and the avoiding opening 6220 in turn to contact the first male conductive part 6211. The effect of contacting and connecting the first male conductive part 6211 and the corresponding female conductive part 721 is achieved.

[0168] It needs to be explained that, in the process of plugging the second male connector 62 and the second female connector 72, the female conductive part 721 used for contacting and connecting the first male conductive part 6211 needs to be in contact with the outer surface of the second male conductive part 6212 first, and when the female conductive part 721 moves to the connecting opening 621b, the female conductive part 721 moves in the direction from the outer edge to the inner core of the second male connector 62 to contact the first male conductive part 6211, so as to achieve the effect of contacting and connecting the female conductive part 721 and the first male conductive part 6211. Because in the direction from the outer edge to the inner core of the second male connector 62, there is a certain distance between the outer surface of the second male conductive part 6212 and the outer surface of the first male conductive part 6211, when the female conductive part 721 is separated from the outer surface of the second male conductive part 6212, under the action of the elastic force of the female conductive part 721 itself, the female conductive part 721 and the first male conductive part 6211 impact and contact, and the impact and contact is used to emit a sound to prompt the user to complete the plugging. And in this way, the structure of each female conductive part 721 in the second female connector 72 is the same, and the production cost of the second female connector 72 is reduced.

[0169] Referring to FIGS. 19 and 20, in some embodiments of the present application, the insulating part 622 is an insulating coating, which is coated on the outer surface of the male conductive part 621 on the inner side and / or on the inner surface of the male conductive part 621 on the outer side. For example, the insulating coating is coated on the outer surface of the male conductive part 621 on the inner side; or the insulating coating is coated on the inner surface of the male conductive part 621 on the outer side; or the outer surface of the male conductive part 621 on the inner side and the inner surface of the male conductive part 621 on the outer side are both coated with the insulating coating. In this way, when the adjacent two male conductive parts 621 are assembled in a sleeved manner, the insulating coating is located between the adjacent two male conductive parts 621, so as to insulate the adjacent two male conductive parts 621 from each other.

[0170] Alternatively, in some other embodiments of the present application, the insulating part 622 is configured as a cylinder. For example, the insulating part 622 is made of rubber or other insulating material, and the insulating part 622 is configured as a cylinder. In the process of manufacturing the second male connector 62, the operator sets the insulating part 622 on the inner side of the male conductive part 621. In this way, when the adjacent two male conductive parts 621 are set and assembled, the insulating coating is located between the adjacent two male conductive parts 621, so as to insulate the adjacent two male conductive parts 621 from each other.

[0171] In combination with FIGS. 17 and 21, in some embodiments of the present application, along the circumference of the second male connector 62, the plurality of male conductive parts 621 are sequentially arranged in abutment, and the insulating part 622 is arranged between the adjacent two male conductive parts 621. The insulating part 622 is arranged between the adjacent two male conductive parts 621 to insulate the adjacent two male conductive parts 621, thereby avoiding the electrical connection between the adjacent two male conductive parts 621 and ensuring that each male conductive part 621 in the second male connector 62 forms an independent conductive path.

[0172] For example, in combination with FIGS. 17 and 21, in an embodiment of the present application, the second male connector 62 includes two male conductive parts 621 and one insulating part 622, wherein the two male conductive parts 621 are respectively a first male conductive part 6211 and a second male conductive part 6212, and the insulating part 622 is arranged between the first male conductive part 6211 and the second male conductive part 6212, so as to insulate the first male conductive part 6211 and the second male conductive part 6212 from each other, thereby realizing that the second male connector 62 has two independent conductive paths. It should be noted that, in this embodiment, the second male connector 62 is taken as an example to be described, but the present application is not limited thereto. In some other embodiments of the present application, the number of male conductive parts 621 in the second male connector 62 can be three, four, five, etc. In the circumference of the second male connector 62, the plurality of male conductive parts 621 are sequentially arranged, so that in the circumference of the second male connector 62, the orientations of the male conductive parts 621 are different from each other. For the second female connector 72 matched with the second male connector 62, each female conductive part 721 in the second female connector 72 has the same structure, thereby reducing the production cost of the second female connector 72.

[0173] In some embodiments of the present application, as shown in FIG. 21, the insulating portion 622 is an insulating coating, and in the two adjacent male conductive portions 621, the insulating coating is coated on the surface of at least one male conductive portion 621 used for connection. For example, as shown in FIG. 21, in an embodiment of the present application, the first male conductive portion 6211 and the second male conductive portion 6212 are symmetrically arranged, the insulating coating is coated on the surface of the first male conductive portion 6211 facing the second male conductive portion 6212, and / or the insulating coating is coated on the surface of the second male conductive portion 6212 facing the first male conductive portion 6211, so as to achieve the effect of arranging the insulating portion 622 between the first male conductive portion 6211 and the second male conductive portion 6212.

[0174] Alternatively, in another embodiment of the present application, the insulating portion 622 is an independent individual made of an insulating material such as rubber, and the insulating portion 622 is configured as a layer member, and the insulating portion 622 is clamped between the first male conductive portion 6211 and the second male conductive portion 6212.

[0175] Referring to FIGS. 18-21, in some embodiments of the present application, along the circumference of the second female connector 72, a plurality of female conductive portions 721 are arranged in sequence to form a docking space 720 for accommodating the second male connector 62. During the plug-in cooperation of the host electrical docking element 401 and the accessory electrical docking element 501, the second male connector 62 extends into the docking space 720, so that along the circumference of the second male connector 62, the plurality of female conductive portions 721 are arranged around the second male connector 62, and each female conductive portion 721 is connected to the corresponding male conductive portion 621 one by one. It is worth noting that the two adjacent female conductive portions 721 are arranged with a spacing, so as to ensure that the two adjacent female conductive portions 721 are insulated from each other. So that when one second female connector 72 and one first male connector 61 are in a connected state, a plurality of independent conductive paths are formed.

[0176] For example, referring to FIGS. 19-21, in some embodiments of the present application, the second female connector 72 has two female conductive portions 721, which are a first female conductive portion 7211 and a second female conductive portion 7212, respectively, and are oppositely and spacedly arranged to form the docking space 720. When the second male connector 62 is connected to the second female connector 72, the first female conductive portion 7211 faces the first male conductive portion 6211 of the second male connector 62 and is in contact with the first male conductive portion 6211, and the second female conductive portion 7212 faces the second male conductive portion 6212 of the second male connector 62 and is in contact with the second male conductive portion 6212. Thus, the effect of forming two independent conductive paths when one second female connector 72 and one first male connector 61 are connected is achieved.

[0177] Referring to FIGS. 19-21, in some embodiments of the present application, the female conductive portion 721 includes a conductive segment 721a and an engaging segment 721b, which are adjacently arranged along the extension direction of the female conductive portion 721, and the engaging segment 721b is elastically deformable and is adapted to engage with the male conductive portion 621.

[0178] It should be understood that, since the plurality of female conductive portions 721 are sequentially arranged along the circumference of the second female connector 72 to form the docking space 720, the ports surrounded by the plurality of engaging segments 721b are interfaces of the docking space 720, and the initial size of the interfaces of the docking space 720 is smaller than the cross-sectional dimension of the second male connector 62. Therefore, during the process that the second male connector 62 extends into the docking space 720 from the interfaces of the docking space 720, the second male connector 62 drives the elastically deformable engaging segments 721b to move away from the second male connector 62, achieving the effect of expanding the interfaces of the docking space 720. Moreover, since the engaging segments 721b are elastically deformable, the engaging segments 721b are tightly pressed against the male conductive portion 621 under the action of elastic force, improving the connection stability of the second male connector 62 and the second female connector 72.

[0179] Referring to FIGS. 18-19, in some embodiments of the present application, the engaging segments 721b of the at least two female conductive portions 721 are staggeredly arranged along the axial direction of the second female connector 72. Alternatively, referring to FIGS. 20-21, in some other embodiments of the present application, the engaging segments 721b of each female conductive portion 721 are flushly arranged. Thus, the second female connector 72 of different configurations can be correspondingly adapted to the second male connector 62 of different configurations, so that the female conductive portions 721 of the second female connector 72 are connected to the male conductive portions 621 of the second male connector 62 one by one.

[0180] In some embodiments of the present application, as shown in FIGS. 14-17, the main electrical docking element 401 further comprises a main connector mounting seat 4011, and the auxiliary electrical docking element 501 further comprises an auxiliary connector mounting seat 5011. One of the main connector mounting seat 4011 and the auxiliary connector mounting seat 5011 is provided with a docking recess 81, and the other of the main connector mounting seat 4011 and the auxiliary connector mounting seat 5011 is correspondingly configured as a docking protrusion 82. The docking protrusion 82 is adapted to extend into the docking recess 81 for docking cooperation, and an arrangement space 820 is formed inside the docking protrusion 82. One of the docking recess 81 and the arrangement space 820 is used to arrange the first female connector 71 and the second female connector 72, and the other of the docking recess 81 and the arrangement space 820 is correspondingly used to arrange the first male connector 61 and the second male connector 62.

[0181] For example, in some embodiments of the present application, as shown in FIGS. 14-17, the main connector mounting seat 4011 is configured as the docking protrusion 82, and the auxiliary connector mounting seat 5011 has the docking recess 81. During the plug-in cooperation of the main electrical docking element 401 and the auxiliary electrical docking element 501, the main connector mounting seat 4011 extends into the docking recess 81. The slot surface of the docking recess 81 abuts against the outer peripheral wall of the main connector mounting seat 4011 to limit the relative movement of the main connector mounting seat 4011 and the auxiliary connector mounting seat 5011, so that the main electrical docking element 401 and the auxiliary electrical docking element 501 are more stably connected and cooperated, the risk of separation of the main electrical docking element 401 and the auxiliary electrical docking element 501 is reduced, and the connection stability of the water purifier 200 and the ice maker 100 is also improved.

[0182] As shown in FIG. 16, the arrangement space 820 inside the main connector mounting seat 4011 is used to arrange the first female connector 71 and the second female connector 72, and the docking recess 81 is used to arrange the first male connector 61 and the second male connector 62. During the plug-in cooperation of the main electrical docking element 401 and the auxiliary electrical docking element 501, the female connectors arranged in the main connector mounting seat 4011 are simultaneously moved into the docking recess 81, and during this process, the male connectors arranged in the docking recess 81 extend into the arrangement space 820, so that the corresponding male connectors and female connectors are one-to-one connected.

[0183] In combination with FIG. 14 and FIG. 16, in some embodiments of the present application, at least one waterproof piece 822 is arranged on the docking protrusion 82, and the waterproof piece 822 is arranged in correspondence with the connecting body arranged in the arrangement space 820, and at least one connecting body is located below the corresponding waterproof piece 822. For example, in an embodiment of the present application, six female connecting bodies (i.e. five first female connecting bodies 71 and one second female connecting body 72) are arranged in the arrangement space 820, and six waterproof pieces 822 are arranged on the docking protrusion 82, and each female connecting body is arranged below each waterproof piece 822.

[0184] It should be understood that the waterproof piece 822 is used to shield the communication hole 821 opened on the docking protrusion 82. During the plug-in cooperation of the host electrical docking element 401 and the accessory electrical docking element 501, the male connecting body arranged in the docking groove 81 extends into the arrangement space 820 through the communication hole 821 to dock with the female connecting body. By arranging the waterproof piece 822, the communication hole 821 is shielded by the waterproof piece 822, and the waterproof performance of the arrangement space 820 is improved.

[0185] In some embodiments, the waterproof piece 822 is an openable waterproof silica gel sheet. The waterproof silica gel sheet is provided with an opening in a cross shape, a rice shape or the like, so that the male connecting body can press the opening of the waterproof silica gel sheet during docking, and then dock with the female connecting body.

[0186] In some embodiments of the present application, the expansion function module 400 can be received and mounted on the water purifier 200. When the ice maker 100 in the multifunctional water purifier is not needed, the ice maker 100 can be detached from the water purifier 200, so that the water purifier 200 is in a single working mode, and the expansion function module 400 is in a received state. When the expansion function module 400 is in the received state, the host electrical docking element 401 and the host waterway docking element 402 in the expansion function module 400 are located in the water purifier 200. Preferably, the expansion function module 400 is entirely received in the water purifier 200, which embodies the overall aesthetics; secondly, it can also avoid the problem of bumping during transportation and use, and finally it can also prevent dust and water.

[0187] In some embodiments of the present application, in combination with FIG. 1 and FIG. 12, when the multifunctional water purifier is in a multifunctional working mode, it can also be understood that the water purifier 200 and the ice maker 100 are in an assembled and cooperated state. At least the host electrical docking element 401 and the host waterway docking element 402 of the expansion function module 400 are located outside the water purifier 200.

[0188] Preferably, when the multifunctional water purifier is in a multifunctional working mode, at least the host electrical docking element 401 and the host waterway docking element 402 in the expansion function module 400 are exposed and mounted on the water purifier 200 for mounting the ice maker 100.

[0189] In combination with FIG. 1 and FIG. 12, the expansion function module 400 in the embodiment is arranged on the water purifier 200 and faces the ice maker 100. Specifically, the expansion function module 400 is arranged at the left bottom of the water purifier 200, and the ice maker 100 is inserted and locked with the main machine electrical connection element 401 and the main machine water connection element 402 in the expansion function module 400 in the direction from left to right. In this embodiment, it is worth noting that the expansion function module 400 is fixedly arranged on the water purifier 200.
