Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household appliances, especially to a milk frother capable of discharging pipeline water. BACKGROUND

[0002] The milk frother is a device specially used for brewing infant milk powder, which can help parents prepare milk powder with appropriate temperature and concentration for infants in a standardized, fast and efficient way. With the acceleration of modern family life rhythm, the milk frother gradually becomes an important helper in the life of child-rearing due to its convenience and functionality. Its main functions include water temperature adjustment, proportion control and rapid mixing of milk powder and water, and some high-end products even have intelligent operation functions such as one-key brewing, cleaning reminder, etc.

[0003] Although the milk frother on the market is increasingly intelligent in functional design, there are still some problems to be solved in actual use. Among them, the residual phenomenon of water and air in the pipeline is a significant pain point. After the milk frother completes water delivery, a small amount of water is often left in the pipeline. These residual water may become a breeding ground for bacteria and other microorganisms if it stays in the pipeline for too long, increasing the likelihood of bacterial growth in the pipeline, thereby contaminating the water system of the milk frother and posing a potential threat to the diet safety of infants.

[0004] In addition, during water delivery, a certain amount of air may be left in the pipeline of the milk frother. These air not only may cause water evaporation and concentration in the pipeline, but also may provide living conditions for some aerobic microorganisms, exacerbating the risk of microbial reproduction.

[0005] Due to the complexity of the internal pipeline design of the milk frother, it is difficult for users to completely remove the residual water and air after daily use. Without regular cleaning, the problem of bacterial growth in the pipeline may become more serious, affecting the normal operation of the equipment and the health of infants. If this problem cannot be effectively solved for a long time, the bacteria in the pipeline may be brought into the milk water during the water delivery process, directly endangering the health of infants, especially infants with low immunity.

[0032] The embodiment of the utility model will be described in detail below in combination with the drawings.

[0033] As Figures 1 to 10 Indicated, a kind of milk adjuster of the utility model of the present embodiment, including machine body 1, water storage heating utensil 2 and waterway mechanism are equipped on the machine body 1, the waterway mechanism includes water supply pump 3 being located in machine body 1, water outlet 4 being located on machine body 1 and water delivery structure being located between water supply pump 3 and water outlet 4, the water supply pump 3 is connected with water storage heating utensil 2, the water delivery structure includes pipeline switching component 5, communication pipeline assembly 6, waste water pipeline assembly 7, water supply pipeline assembly 8 and water outlet pipeline assembly 9, water outlet pipeline assembly 9 is connected with water outlet 4 and communication pipeline assembly 6 respectively, water supply pipeline assembly 8 is connected with water supply pump 3 and communication pipeline assembly 6 respectively, waste water pipeline assembly 7 is connected with communication pipeline assembly 6, the pipeline switching component 5 is transmission connection with communication pipeline assembly 6, the pipeline switching component 5 can drive communication pipeline assembly 6 to act, to make water supply pipeline assembly 8 switch to be communicated with water outlet pipeline assembly 9 by communication pipeline assembly 6, or switch to be communicated with waste water pipeline assembly 7.

[0034] Specifically, the waterway mechanism and the pipeline switching component cooperate to realize the function of automatically emptying the residual water in the pipeline. When the user needs to prepare milk powder, the milk preparation device starts the water supply pump 3 to deliver the hot water in the water storage and heating vessel 2 to the communication pipeline assembly 6 through the water delivery pipeline assembly 8. The user can manually or through an automatic program start the pipeline emptying function. The pipeline switching component 5 switches the pipeline to the “drainage mode”, so that the communication pipeline assembly 6 connects the water delivery pipeline assembly 8 and the waste water pipeline assembly 7. The water body is delivered from the water delivery pipeline assembly 8 to the waste water pipeline assembly 7 through the water supply pump 3, so as to pre-drain the residual water body and air in the water delivery pipeline assembly 8, and clean the water delivery pipeline assembly 8 with new water body. That is, before preparing milk, the water delivery pipeline assembly 8 is flushed, and then the dirty water is drained through the waste water pipeline assembly 7, so as to ensure the cleanliness of the water body before preparing milk and ensure the health of the baby's diet.

[0035] When the flushing is completed, the pipeline switching component 5 switches the pipeline to the “water delivery mode”, so that the communication pipeline assembly 6 connects the water delivery pipeline assembly 8 and the water outlet pipeline assembly 9, so as to ensure that the clean water body flows smoothly to the water outlet 4. The user obtains hot water with a suitable temperature through the water outlet 4 for preparing milk powder.

[0036] Preferably, after the milk preparation is completed, the user can manually or through an automatic program start the pipeline emptying function. The pipeline switching component 5 switches the pipeline to the “drainage mode” again to clean the water delivery pipeline assembly 8 again and empty the air in it, so that the water body fills the water delivery pipeline assembly 8, avoids the damp breeding of bacteria in the water delivery pipeline assembly 8, reduces the risk of microbial growth caused by the combination of air and water, and ensures the cleanliness of the water delivery pipeline assembly 8.

[0037] When the drainage is completed or the equipment is used, the pipeline switching component 5 switches the pipeline back to the original state, so that the equipment can enter the next round of use at any time, and ensures that the waterway is smooth and unobstructed.

[0038] With the above design, the user does not need to manually disassemble and clean the pipeline. The equipment can automatically empty the residual water in the pipeline after running, reduces the cleaning workload, greatly improves the use convenience, the pipeline switching component 5 realizes the seamless switching of the water delivery and drainage modes, ensures the efficient operation of the equipment between different functions, and avoids complex operation steps.

[0039] For example, Figures 1 to 10As shown, the communication pipeline assembly 6 of the present embodiment includes a communication housing 61 and a switching housing 62 arranged in the communication housing 61, the communication housing 61 is provided with a water outlet pipeline connecting nozzle 611 communicated with the water outlet pipeline assembly 9, a water feeding pipeline connecting nozzle 612 communicated with the water feeding pipeline assembly 8, and a waste water pipeline connecting nozzle 613 communicated with the waste water pipeline assembly 7, the switching housing 62 is in transmission connection with the pipeline switching component 5, the switching housing 62 is provided with a switching pipeline 621, when the pipeline switching component 5 drives the switching housing 62 to move in the communication housing 61, the switching pipeline 621 can communicate the water outlet pipeline connecting nozzle 611 and the water feeding pipeline connecting nozzle 612, or the switching pipeline 621 can communicate the waste water pipeline connecting nozzle 613 and the water feeding pipeline connecting nozzle 612.

[0040] When the device needs to output hot water for milk flushing, the pipeline switching component 5 drives the switching housing 62 to move to a specified position in the communication housing 61, and the switching pipeline 621 communicates the water outlet pipeline connecting nozzle 611 and the water feeding pipeline connecting nozzle 612 in the communication housing 61.

[0041] The heated water flows from the water storage and heating container 2, through the water feeding pipeline assembly 8, into the switching pipeline 621, and then through the water outlet pipeline assembly 9 to the water outlet 4 for use by the user.

[0042] When the device performs pre-flushing before milk flushing or emptying cleaning after milk flushing, the pipeline switching component 5 drives the switching housing 62 to move, the switching pipeline 621 changes its communication state, the switching pipeline 621 communicates the waste water pipeline connecting nozzle 613 and the water feeding pipeline connecting nozzle 612, the water flow transported through the water feeding pipeline assembly 8 directly enters the waste water pipeline assembly 7, and the residual water and air in the water feeding pipeline assembly 8 are discharged, achieving the effect of cleaning and emptying.

[0043] Preferably, the pipeline switching component 5 is linked with the switching housing 62, the switching housing 62 can rotate or translate in the communication housing 61, and the switching pipeline 621 in the switching housing 62 can control the communication state between different water routes when it is in different positions in the communication housing 61, realizing the switching of water feeding and water discharging.

[0044] Preferably, the switching housing 62 can be accurately positioned in the communication housing 61, and the switching pipeline 621 realizes the rapid switching of water route state without the need for complex manual adjustment.

[0045] Preferably, the above design supports two functions of "water feeding mode" and "water discharging mode", which can meet the water route demand in different scenes such as milk flushing, pre-flushing, emptying cleaning, etc., and significantly improves the use efficiency.

[0046] Preferably, the communication functions of the water supply pipeline, the water outlet pipeline and the waste water pipeline are concentrated in the communication shell 61 and the switching shell 62 to complete, avoiding complex external pipeline connection, simplifying the waterway design, making the equipment inside more compact, and without the need for users to manually disassemble or adjust the pipeline, all switching operations are completed inside the communication pipeline assembly 6, improving the overall integration and ease of use of the equipment.

[0047] Further, the user does not need to manually clean or adjust the waterway, and the equipment can complete mode switching and perform pre-flushing, milk flushing or emptying cleaning by program or key triggering, which is simple and convenient to operate.

[0048] Further, the emptying mode automatically removes the pipeline residue, and the user does not need to frequently disassemble the equipment to clean the pipeline, reducing the cleaning time and maintenance difficulty.

[0049] Preferably, the pipeline switching component 5 can drive the switching shell 62 to translate or rotate in the communication shell 61, so that the waterway system can be flexibly switched between the "water supply mode" and the "drainage mode", and this design realizes the efficiency and reliability of waterway switching through mechanical precise control.

[0050] Preferably, in the present embodiment, the pipeline switching component 5 can drive the switching shell 62 to rotate in the communication shell 61, and the pipeline switching component 5 (such as a stepper motor, a knob or a gear driving mechanism) drives the switching shell to rotate to a precise angle around the center axis by applying a rotating force, and the switching pipeline 621 in the switching shell is aligned with the connection nozzle in the communication shell after rotating to the specified angle, thereby realizing the communication and switching of the waterway.

[0051] When the switching pipeline 621 is in communication with the water outlet pipeline connection nozzle 611 and the water supply pipeline connection nozzle 612, the water flows to the water outlet.

[0052] When the switching pipeline 621 is in communication with the waste water pipeline connection nozzle 613 and the water supply pipeline connection nozzle 612, the water flows into the waste water pipeline to realize cleaning and emptying.

[0053] Preferably, in other embodiments, the pipeline switching component 5 can drive the switching shell 62 to internally linearly translate in the communication shell 61, and the pipeline switching component 5 (such as a motor driving device, a spring mechanism or a manual push rod) drives the switching shell to move forward or backward or left or right in the communication shell along the fixed track by pushing or sliding.

[0054] When the switching shell is translated to a specific position, the internal switching pipeline 621 is docked with different connection nozzles (water outlet pipeline connection nozzle, water supply pipeline connection nozzle, waste water pipeline connection nozzle) on the communication shell, thereby completing the waterway switching.

[0055] When the switching pipe 621 is connected with the water outlet pipe connection nozzle 611 and the water feeding pipe connection nozzle 612, water flows from the water storage device to the water outlet for users to flush milk.

[0056] When the switching pipe 621 is connected with the waste water pipe connection nozzle 613 and the water feeding pipe connection nozzle 612, water is discharged through the waste water pipe assembly to achieve cleaning and emptying.

[0057] Through the translational or rotational movement of the switching housing 62 in the communication housing 61, whether it is translation or rotation, the pipe switching component 5 can accurately control the movement or angle of the switching housing 62, ensuring that the switching pipe 621 is completely connected with the target connection nozzle, avoiding water leakage or poor connection during waterway switching. The appropriate design can be selected according to the actual needs.

[0058] As shown in Figures 1 to 10 The pipe switching component 5 of the present embodiment can drive the switching housing 62 to rotate in the communication housing 61, and the water outlet pipe connection nozzle 611, the water feeding pipe connection nozzle 612 and the waste water pipe connection nozzle 613 are circumferentially spaced along the outer wall of the communication housing 61, and the water feeding pipe connection nozzle 612 is located between the water outlet pipe connection nozzle 611 and the waste water pipe connection nozzle 613, and the two ends of the switching pipe 621 are circumferentially spaced along the outer wall of the switching housing 62.

[0059] Specifically, the water outlet pipe connection nozzle 611, the water feeding pipe connection nozzle 612 and the waste water pipe connection nozzle 613 are circumferentially spaced along the outer wall of the communication housing 61, forming a circular arrangement, and the water feeding pipe connection nozzle 612 is located between the water outlet pipe connection nozzle 611 and the waste water pipe connection nozzle 613 as an intermediate connection point responsible for guiding water flow.

[0060] Specifically, the two ends of the switching pipe 621 in the switching housing 62 are also circumferentially spaced along the outer wall of the switching housing, and the two ends of the switching pipe are responsible for connecting two of the three connection nozzles, for example: the water feeding pipe connection nozzle and the water outlet pipe connection nozzle, or the water feeding pipe connection nozzle and the waste water pipe connection nozzle. The switching pipe can be connected with different connection nozzles to realize different modes of switching.

[0061] Specifically, the pipe switching component 5 drives the switching housing 62 to rotate around the axis of the communication housing 61, and the switching pipe 621 moves with the switching housing. As the switching housing rotates to different angles, the two ends of the switching pipe are respectively aligned with and connected to different connection nozzles, thereby controlling the flow direction of water.

[0062] When the switching housing is rotated to a specific angle, one end of the switching pipe is connected with the water feeding pipe connection nozzle 612, and the other end is connected with the water outlet pipe connection nozzle 611, so that hot water flows from the water feeding pipe to the water outlet.

[0063] When one end of the switching pipe is docked with the water supply pipe connection nozzle 612 and the other end is docked with the waste water pipe connection nozzle 613, the excess water or residual water is discharged through the waste water pipe, and after the switching is completed, the water path can be automatically converted according to the user's needs to provide clean hot water or empty the pipe.

[0064] Specifically, by distributing the connection nozzles 611, 612 and 613 along the outer wall of the communication housing 61, the water path switching function is concentrated inside the communication housing, avoiding complex external pipe connections.

[0065] Moreover, the rotating action of the switching housing 62 does not require complex mechanical devices, occupies less space, and the overall design of the equipment is more compact, making it suitable for small household appliances such as milk frothers.

[0066] Preferably, the switching housing 62 precisely docks the switching pipe 621 with the target connection nozzle through a rotating action, achieving seamless switching of the water path, high-efficiency water path switching, avoiding water leakage or poor docking, and the rotating action is quick, allowing the water path mode to be converted from "water supply mode" to "drainage mode" in a short time, meeting the user's demand for smooth operation of the equipment.

[0067] As shown in Figures 1 to 10 the water supply pipe connection nozzle 612 is located above the water outlet pipe connection nozzle 611 and the waste water pipe connection nozzle 613.

[0068] Specifically, the water supply pipe connection nozzle 612 is located at a higher position in the entire communication housing 61 and is in the central position, while the water outlet pipe connection nozzle 611 is located at a lower position in the communication housing 61 and forms a straight path with the water supply pipe connection nozzle 612, used to provide water for milk frothing to the water outlet, and the waste water pipe connection nozzle 613 is located at another low position in the communication housing 61 and is connected with the water supply pipe connection nozzle 612 when waste water is introduced to the waste water pipe. This up-and-down distribution layout makes the water supply pipe connection nozzle 612 the key hub of the entire water path switching system, which can control the water flow to the water outlet or the waste water pipe.

[0069] Specifically, since the water supply pipe connection nozzle 612 is located above, the water flow can better utilize gravity when supplying or draining water, reducing water flow resistance. This design makes the water flow smoother, while reducing the demand for pump power during transportation, improving the efficiency of the equipment.

[0070] Preferably, the water supply pipe connection nozzle 612 is located in the center as the hub of the water flow, which can quickly guide the water flow to the water outlet or the waste water pipe according to the connection condition of the switching pipe 621, making the switching more smooth and improving the efficiency of the water path switching. Moreover, the water flow flows from the top to the bottom, utilizing the natural tendency of gravity, reducing the resistance during water flow switching, and improving the efficiency of water supply and drainage.

[0071] The up-and-down distribution design enables the water flow to be completely drained after switching, especially in the drainage mode, the gravity further helps to eliminate the residual water in the pipeline, reducing the risk of bacterial breeding, and because the water supply pipeline connection nozzle 612 is at a higher position and maintains a certain physical distance from the waste water pipeline connection nozzle 613, effectively preventing waste water from flowing back to the water supply pipeline, ensuring water quality safety.

[0072] Preferably, the vertical distribution of the three connection nozzles optimizes the space utilization, making the design of the communication housing 61 more compact, and this layout reduces the occupation of horizontal space, making it possible to miniaturize the overall device.

[0073] Further, the water flow can also flow from the water supply pipeline to the water outlet or waste water pipeline by gravity, reducing the pressure on the pump and prolonging the service life of the pump.

[0074] As shown in Figures 1 to 10 The communication housing 61 and the switching housing 62 are provided with a positioning assembly 63, the positioning assembly 63 has a water supply position and a drainage position, and the positioning assembly 63 can limit the switching housing 62 to the water supply position or the drainage position.

[0075] By providing the positioning assembly 63 between the communication housing 61 and the switching housing 62, the position of the switching housing 62 can be precisely controlled, so that it can be switched between the "water supply position" and the "drainage position" and stably stay, which ensures the accuracy and reliability of the waterway switching, and improves the service life and operation convenience of the device.

[0076] Specifically, the positioning assembly 63 can control the rotating or moving action of the switching housing 62, so that it can be switched between the water supply position and the drainage position, and accurately positioned at the target position, avoiding the occurrence of deviation or misalignment.

[0077] When the switching housing 62 reaches the target position, the positioning assembly 63 fixes it by locking or limiting, ensuring that the switching pipeline 621 is accurately connected with the connection nozzles (611, 612, 613) in the communication housing 61, preventing accidents during waterway switching.

[0078] Specifically, in the water supply position, the switching pipeline 621 of the switching housing 62 connects the water supply pipeline connection nozzle 612 and the water outlet pipeline connection nozzle 611, realizing the water supply function (water flow to the water outlet), and in the drainage position, the switching pipeline 621 of the switching housing 62 connects the water supply pipeline connection nozzle 612 and the waste water pipeline connection nozzle 613, realizing the drainage function (water flow to the waste water pipeline).

[0079] Preferably, the specific structure of the positioning assembly 63 can include the following forms, such as:

[0080] Mechanical limit mechanism:

[0081] The positioning component 63 provides a limiting device (such as a slot, positioning protrusion, etc.) between the switching housing 62 and the connecting housing 61, which restricts the switching housing 62 to the water supply position or the drainage position by means of physical restriction.

[0082] Spring reset mechanism:

[0083] When the switching housing 62 is rotated or translated to a designated position by a spring-loaded locking device, the positioning component 63 automatically pops out to fix the switching housing 62.

[0084] Magnetic positioning:

[0085] The magnetic locking of the switching housing 62 at the target position is achieved by utilizing the attraction between the magnet and the metal part.

[0086] Electromagnetic or inductive positioning:

[0087] The position of the switching housing 62 is detected in real time through electromagnetic induction or sensor control. When the target position is reached, the locking function of the positioning component 63 is automatically triggered.

[0088] Preferred, such as Figures 1 to 10 As shown, in this embodiment, the switching housing 62 is rotatably connected to the connecting housing 61. The positioning component 63 includes a positioning plate 631 and a positioning protrusion 632. The positioning protrusion 632 has an arc-shaped cross-section. The water supply position and the drainage position are located at the two ends of the positioning protrusion 632, respectively. When the switching housing 62 rotates on the connecting housing 61 and rotates until the outer wall of the positioning plate 631 abuts against one end of the positioning protrusion 632, the switching housing 62 rotates to the water supply position or the drainage position.

[0089] Specifically, the switching housing 62 is rotatably installed inside the connecting housing 61 and rotates around the axis of the connecting housing to achieve docking of the switching pipe 621 with the connecting nozzles (611, 612, 613).

[0090] Specifically, the positioning plate 631 serves as a limiting device for switching positions and works in conjunction with the positioning protrusion 632. By rotating the switching housing 62, the outer wall of the positioning plate 631 abuts against one end of the positioning protrusion 632, thereby achieving precise positioning of the switching position and limiting the rotation angle of the switching housing 62 on the connecting housing 61.

[0091] When the switching shell 62 is rotated to the "water delivery position", the outer wall of the positioning plate 631 abuts against one end of the positioning protrusion 632, and the switching shell 62 is locked in the water delivery position. Similarly, when the switching shell 62 is rotated to the "drainage position", the outer wall of the positioning plate 631 abuts against the other end of the positioning protrusion 632, and the switching shell 62 is locked in the drainage position.

[0092] Specifically, the two ends of the positioning protrusion 632 correspond to the water delivery position and the drainage position respectively, ensuring that the switching shell 62 accurately stays between the two positions. When the switching shell 62 is rotated to the target position (water delivery position or drainage position), the positioning assembly 63 provides reliable limiting and fixing, ensuring the accuracy of waterway switching, thereby avoiding the problems of water leakage or poor connection due to position deviation.

[0093] Specifically, the positioning plate 631 and the positioning protrusion 632 have simple design structure and small space occupation, and are easy to integrate into the inside of the communication shell 61, which can make the overall design of the device more compact.

[0094] Preferably, the positioning plate 631 is arranged at one end of the switching shell 62, the positioning protrusion 632 is arranged on the communication shell 61 without corresponding arrangement of the positioning plate 631, and the rotation range of the positioning plate 631 is located between the two ends of the positioning protrusion 632.

[0095] As shown in Figures 1 to 10 the wastewater pipeline assembly 7 of the present embodiment includes a wastewater delivery pipeline 71 connected by the communication pipeline assembly 6.

[0096] When the switching shell 62 of the waterway switching system is in the drainage position, the switching pipeline 621 communicates the water delivery pipeline connection mouth 612 with the wastewater pipeline connection mouth 613, and the wastewater flows into the wastewater delivery pipeline 71 through the communication pipeline assembly 6, and is directly introduced into the wastewater collection device (such as a wastewater tank) of the device or external drainage facilities (such as a sewer pipeline).

[0097] Preferably, the design of the wastewater delivery pipeline 71 is usually combined with the overall structure of the device and the direction of gravity, and the gravity and appropriate water pressure are used to improve the efficiency of wastewater discharge.

[0098] As shown in Figures 1 to 10 the wastewater pipeline assembly 7 of the present embodiment further includes a wastewater tank 72 arranged on the machine body 1, and the wastewater delivery pipeline 71 can deliver water to the wastewater tank 72 for collection.

[0099] Specifically, the wastewater tank 72 collects wastewater, avoids direct wastewater discharge, maintains the cleanliness of the use environment, and the user only needs to empty the wastewater tank 72 regularly, without frequent wastewater discharge treatment, simple operation, and wastewater directly enters the wastewater tank 72 through the wastewater conveying pipeline 71, which is completely isolated from other pipeline systems to avoid cross contamination and ensure the hygiene of the internal waterway of the equipment.

[0100] As shown in Figures 1 to 10 The first assembly part 11 is provided on the body 1, and the wastewater tank 72 can be assembled and disassembled at the first assembly part 11 through the assembly opening. The top of the wastewater tank 72 is provided with a wastewater inlet 721, and the top of the first assembly part 11 is provided with a connecting opening connected with the wastewater conveying pipeline 71. The connecting opening can allow the water in the wastewater conveying pipeline 71 to be conveyed to the wastewater tank 72 through the wastewater inlet 721.

[0101] When the equipment is running, wastewater is introduced into the wastewater conveying pipeline 71 through the waterway switching system, the wastewater conveying pipeline 71 guides the wastewater to the connecting opening at the top of the first assembly part 11, and the wastewater is discharged into the wastewater inlet 721 at the top of the wastewater tank 72, and finally collected in the wastewater tank 72.

[0102] When the wastewater capacity in the wastewater tank 72 is close to full, the user can easily take it out through the assembly opening of the first assembly part 11, pour out the wastewater and clean the wastewater tank, and then the wastewater tank 72 can be reassembled into the first assembly part 11 for continuous use.

[0103] The sealing design between the connecting opening at the top of the first assembly part 11 and the wastewater inlet 721 ensures that there is no leakage during the wastewater conveying process. After the wastewater tank 72 is assembled in place, it forms a tight fit with the first assembly part 11 to prevent wastewater from leaking due to improper assembly.

[0104] Specifically, the assembly opening of the first assembly part 11 is designed reasonably, and the user can easily insert or remove the wastewater tank 72, which is simple and labor-saving.

[0105] Preferably, the installation position of the wastewater tank 72 is designed inside the body 1, which is integrated with the layout of the first assembly part 11 and the wastewater conveying pipeline 71, so that the overall structure of the equipment is more compact and beautiful.

[0106] As shown in Figures 1 to 10 The second assembly part 12 is provided in the body 1 and can assemble the communicating pipeline assembly 6. The second assembly part 12 is located above the wastewater tank 72, so that the input end of the wastewater conveying pipeline 71 is higher than the output end, so that the water in the wastewater conveying pipeline 71 can be conveyed to the wastewater tank 72 by the weight of the water.

[0107] When the equipment is running, wastewater generated from cleaning, switching or other operations is introduced into the wastewater conveying pipe 71 through the connecting pipe assembly 6. The input end of the wastewater conveying pipe 71 is higher than the output end. Under the action of gravity, the wastewater flows automatically along the pipe to the wastewater tank 72. The design of the wastewater conveying pipe 71 utilizes the weight of the water body to achieve the gravity flow of wastewater, without the need for additional pumps or power support, which simplifies the structure of the wastewater conveying system. This design makes full use of the internal space layout of the equipment to ensure that the wastewater can be discharged into the wastewater tank 72 quickly and smoothly.

[0108] Specifically, the vertical arrangement of the second assembly section 12 and the wastewater tank 72 makes full use of the space inside the machine body 1 and improves the overall structural compactness of the equipment.

[0109] like Figures 1 to 10 As shown, the water storage heating element 2 is detachably installed on the body 1, or it is an integrally formed structure with the body 1. Preferably, in this embodiment, a coupler assembly is provided between the bottom of the water storage heating element 2 and the body 1 to achieve detachable connection. In other embodiments, the water storage heating element 2 is a water tank with a heating element installed on the body 1. A suitable design can be selected according to actual needs.
