[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, this utility model embodiment provides a mini washing machine 100, including: a base 110, and a washing drum 120 detachably connected to the base 110. A drive motor 130 is provided inside the base 110, and a pulsator 140 is rotatably connected to the base 110, and the pulsator 140 is driven by the drive motor 130. The washing drum 120 is used to hold clothes to be washed, and the washing drum 120 can be sealed to the base 110. An electrolysis module 150 is also provided on the base 110, and the electrolysis module 150 is located on one side below the pulsator 140. The electrolysis module 150 is used to electrolyze and generate hypochlorous acid.

[0022] Specifically, the base 110, as the basic component of the mini washing machine 100, houses a drive motor 130, which is the power source for the washing machine 100 to perform its washing function. A pulsator 140 is rotatably connected to the base 110, and the pulsator 140 is connected to the drive motor 130. When the drive motor 130 operates, it drives the pulsator 140 to rotate, generating water flow that rinses and rubs the clothes placed in the washing drum 120, achieving the washing purpose. The detachable connection between the washing drum 120 and the base 110 allows users to easily remove the washing drum 120 for separate cleaning after washing, preventing dirt residue and bacterial growth inside the drum and ensuring hygiene for the next wash. An electrolysis module 150 is also located on the base 110, below the pulsator 140. The main function of the electrolysis module 150 is to electrolyze and generate hypochlorous acid, a strong oxidizing chemical substance with highly effective sterilization and disinfection capabilities. During the washing process, the electrolysis module 150 uses water inside the washing machine as an electrolyte to produce hypochlorous acid through an electrolytic reaction. This enhances the cleaning effect, and the hypochlorous acid can kill bacteria, mites, and other microorganisms on clothes, compensating for the lack of sterilization and disinfection functions in traditional mini washing machines 100 due to their limited space and structure. It should be noted that to ensure sufficient hypochlorous acid is produced during electrolysis, a small amount of salt can be added to the washing drum 120, or a detergent containing salt can be used.

[0023] The mini washing machine 100 provided in this embodiment of the application, through the transmission connection between the drive motor 130 and the pulsator 140, can stably provide power to the pulsator 140, ensuring that the pulsator 140 continuously and efficiently agitates the water and clothes during the washing process, achieving a good cleaning effect. This structural design is simple and reliable, meeting the requirements of the mini washing machine 100 for compact space and practical function. In addition, the sealed connection design between the washing drum 120 and the base 110 improves the safety and stability of the washing machine operation. At the same time, the detachable connection of the washing drum 120 facilitates deep cleaning by users, maintaining a hygienic environment inside the washing machine and further extending the service life of the washing machine. By setting an electrolysis module 150 in the base 110 to generate hypochlorous acid, it can effectively kill a variety of bacteria and mites on clothes, thereby improving the sterilization and disinfection effect when washing clothes, providing sufficient hygiene protection for scenarios such as mothers washing baby clothes and women washing underwear. Compared with traditional washing machines, it greatly improves the functionality and practicality of the product, thereby improving the user experience.

[0024] When the impeller 140 is connected to the drive motor 130, the output shaft of the drive motor 130 can extend out of the base 110, and the impeller 140 can be engaged with the output shaft to achieve the required transmission connection, thereby simplifying the connection method.

[0025] like Figure 3 As shown, the electrolysis module 150 includes a first electrode 152 and a second electrode 154 arranged at intervals, and the first electrode 152 and the second electrode 154 are respectively fixedly connected to the base 110.

[0026] Specifically, the first electrode 152 and the second electrode 154 are fixed to the base 110, ensuring the stability of the first electrode 152 and the second electrode 154 during the operation of the mini washing machine 100 and preventing the electrode positions from shifting due to factors such as vibration of the mini washing machine 100, which would affect the electrolysis effect. In practical applications, one of the first electrode 152 and the second electrode 154 is connected to the positive terminal of the power supply, and the other is connected to the negative terminal of the power supply, so as to facilitate electrolysis during the mini washing process. In addition, the first electrode 152 and the second electrode 154 are spaced apart to avoid short circuits during use and ensure safety during use.

[0027] like Figure 4 As shown, the first electrode 152 includes a first connecting portion 1522 and a plurality of first electrode pieces 1524 connected to the first connecting portion 1522. The first electrode pieces 1524 are arc-shaped and extend outward on both sides of the first connecting portion 1522. The second electrode 154 includes a second connecting portion 1542 and a plurality of second electrode pieces 1544 connected to the second connecting portion 1542. The second electrode pieces 1544 are arc-shaped and extend outward on both sides of the first connecting portion 1522. The first electrode pieces 1524 and the second electrode pieces 1544 are arranged alternately along the radial direction of the circumference.

[0028] Specifically, the first electrode 152 and the second electrode 154 adopt an arc-shaped structure, significantly increasing the contact area with the washing water. During electrolysis, a larger contact area leads to a more complete electrolytic reaction, more effectively converting electrical energy into chemical energy and generating more hypochlorous acid. The first electrode 1524 and the second electrode 1544 are arranged alternately radially along the circumference, increasing the contact area between the electrodes and the liquid while minimizing the space occupied by the first electrode 152 and the second electrode 154. This satisfies the requirements of increasing the contact area and improving electrolysis efficiency while also fully considering the limited space of the mini washing machine 100. Through a reasonable shape design and arrangement, the functions of the first electrode 152 and the second electrode 154 are optimized without occupying excessive space, meeting the compact structural requirements of the mini washing machine 100.

[0029] like Figure 2 As shown, the base 110 is provided with an annular rim 1142, the impeller 140 includes a circular base plate 142 and an annular sidewall 144 provided on the edge of the circular base plate 142. The annular sidewall 144 and the inner wall of the annular rim 1142 have a gap, and the height of the impeller 140 is higher than the height of the annular rim 1142.

[0030] Specifically, a gap exists between the annular sidewall 144 and the inner wall of the annular rim 1142. This gap ensures that the impeller 140 does not interfere with the annular rim 1142 during rotation, allowing the impeller 140 to rotate freely and smoothly. It also prevents clothes from accidentally getting stuck under the impeller 140, ensuring reliability during the washing process. Furthermore, the design of the impeller 140 being higher than the annular rim 1142 allows it to more effectively agitate the water flow during rotation. The higher impeller 140 can create a wider and stronger water circulation, better dispersing clothes within the water flow and increasing contact between clothes, water, and detergent, thereby improving cleaning effectiveness. Additionally, the circular base plate 142 is equipped with multiple smooth protrusions to enhance water agitation, further improving the washing effect.

[0031] like Figure 3 and Figure 7 As shown, the base 110 is also provided with an annular protrusion 116 located on one side of the annular circumference 1142. The electrolytic module 150 is disposed inside the annular protrusion 116. The annular protrusion 116 includes a first edge 1162 and a second edge 1164 that are connected to each other. The annular circumference 1142 is flush with the height of the first edge 1162 and they are joined to form a closed area. The second edge 1164 is located inside the annular circumference 1142, and the height of the second edge 1164 is lower than the height of the annular circumference 1142, so as to avoid the impeller 140.

[0032] Specifically, the annular protrusion 116 provides a relatively stable and safe working environment for the electrolysis module 150. During the washing process, the impact and fluctuation of the water flow are significant. If the electrolysis module 150 is directly exposed to the water flow, it may be affected by the impact of the water flow, causing the first electrode 152 or the second electrode 154 to loosen or be damaged, or affecting the normal progress of the electrolysis reaction. The annular protrusion 116 can effectively reduce the impact of external factors on the electrolysis module 150, ensuring the normal operation of the electrolysis module 150 and improving its service life and reliability. In addition, the closed area formed by the annular protrusion 116 and the annular rim 1142 helps to ensure a smoother transition between the annular protrusion 116 and the annular rim 1142, thus ensuring overall smoothness and reducing wear on the clothes being washed. The design that the height of the second edge 1164 is lower than that of the annular rim 1142 cleverly solves the spatial conflict problem between the rotation of the impeller 140 and the annular protrusion 116. When the impeller 140 rotates at high speed, it needs sufficient space to ensure smooth operation. If the height of the annular protrusion 116 is too high, it may obstruct the rotation of the impeller 140 and affect the normal operation of the washing machine. This avoidance design ensures that the impeller 140 can rotate freely, while also ensuring the protection of the electrolytic module 150 by the annular protrusion 116, thus achieving the rationality and coordination of the structural design.

[0033] like Figure 3 and Figure 5 As shown, in one optional embodiment of this application, the base 110 includes a seat body 112 and a top cover 114 connected to the seat body 112. A first electrode 152 and a second electrode 154 are disposed on the top cover 114. A first positioning member 156 is connected to the first electrode 152, and a second positioning member 158 is connected to the second electrode 154. The first positioning member 156 and the second positioning member 158 extend through the top cover 114 into the seat body 112.

[0034] Specifically, the first electrode 152 and the second electrode 154 are mounted on the top cover 114 and extend through the top cover 114 into the base 112 via positioning components. This mounting method provides double fixation for the electrodes. During the operation of the mini washing machine 100, vibrations and shaking will occur. If the first electrode 152 and the second electrode 154 are not securely mounted, they may shift or even fall off, affecting the normal operation of the electrolysis module 150. This mounting structure effectively resists the influence of external vibrations and other factors, ensuring that the first electrode 152 and the second electrode 154 are always in the correct position, ensuring the stable progress of the electrolysis reaction, and thus guaranteeing the reliability of the washing machine's sterilization and disinfection function.

[0035] like Figure 6 and Figure 7As shown, in another optional embodiment of this application, the base 110 includes a seat body 112 and a top cover 114 connected to the seat body 112. The top cover 114 is provided with a receiving cavity 118 extending into the seat body 112. A first electrode 152 and a second electrode 154 are disposed at the bottom of the receiving cavity 118. A first positioning member 156 is connected to the first electrode 152, and a second positioning member 158 is connected to the second electrode 154. The first positioning member 156 and the second positioning member 158 extend through the receiving cavity 118 into the seat body 112.

[0036] Specifically, a receiving cavity 118 is provided on the top cover 114 to install the first electrode 152 and the second electrode 154, providing an independent and regular installation space for the first electrode 152 and the second electrode 154. Compared with directly installing the first electrode 152 and the second electrode 154 on the top cover 114, this method achieves the above-mentioned effects while also allowing sufficient washing water to be filled into the receiving cavity 118. As a result, when the impeller 140 rotates, the impact on the contact between the first electrode 152 and the second electrode 154 and the water is minimized, which helps to ensure reliable electrolysis.

[0037] It should be noted that the first positioning component 156 and the second positioning component 158 ​​can be bolted and secured with nuts on the back of the top cover 114. The nuts can be directly heat-fused to the top cover 114 for easy engagement with the first and second positioning components 156 and 158. Furthermore, to ensure a tight seal at the connection between the first and second positioning components 156 and 158 and the top cover 114, sealing gaskets can be installed at corresponding positions on the top cover 114 to prevent washing water from leaking into the base 110. Simultaneously, the ends of the first and second positioning components 156 and 158 extending into the base 112 are used to connect the positive and negative terminals of the power supply, serving both as positioning components and conductive components, which improves the compactness of the connection and simplifies the connection method.

[0038] like Figure 3 and Figure 6 As shown, a hollow cover 159 is also provided inside the annular protrusion 116, and a retaining part 1166 is provided inside the annular protrusion 116, with the hollow cover 159 being retained at the retaining part 1166.

[0039] Specifically, the perforated cover 159 provides a protective barrier for the electrolysis module 150. During washing, some debris (such as hair and fibers) may fall onto the clothes. If this debris enters the electrolysis module 150, it may become entangled on the first electrode 152 or the second electrode 154, affecting the electrolysis reaction and potentially causing short circuits. The perforated cover 159 prevents debris from entering while its perforated design allows water to flow smoothly, enabling the electrolysis module 150 to function normally, providing both protection and ventilation. Furthermore, the perforated cover 159 is snap-fitted into the annular protrusion 116, allowing for easy removal when the electrolysis module 150 needs inspection, maintenance, or cleaning. This facilitates timely cleaning of debris on the perforated cover 159 and around the electrolysis module 150, keeping the electrolysis module 150 clean, ensuring it remains in good working order, and extending its service life.

[0040] In an optional embodiment of this application, a storage battery is provided inside the seat 112, and the first positioning member 156, the second positioning member 158 and the drive motor 130 are electrically connected to the storage battery.

[0041] By adopting the above design, the mini washing machine 100 is freed from dependence on an external power outlet. Users can use the mini washing machine 100 in places without power outlets (such as outdoors, or in a corner of a room without a suitable outlet), greatly expanding the usage scenarios of the mini washing machine 100. Whether traveling, camping, or in some special environments, the mini washing machine 100 can be conveniently used to wash clothes, improving the product's practicality and user experience.

[0042] like Figure 3 As shown, the outer ring of the top cover 114 is provided with a bidirectional protruding first interface 1144 and a second interface 1146. The first interface 1144 is threadedly connected to the cleaning cylinder 120. A sealing gasket is also provided on the top cover 114, which abuts against the cleaning cylinder 120 and the top cover 114. The second interface 1146 is inserted into the base 112, and a sealing ring is provided between the second interface 1146 and the base 112.

[0043] Specifically, the first interface 1144 is threadedly connected to the washing drum 120. This threaded connection ensures a tight fixation between the washing drum 120 and the top cover 114, and facilitates user disassembly and installation. A sealing gasket is also provided on the top cover 114, which abuts against the washing drum 120 and the top cover 114, further enhancing the sealing of the connection and preventing water leakage during washing. The second interface 1146 is inserted into the base 112, and a sealing ring is provided between the second interface 1146 and the base 112. The sealing ring ensures a tight seal between the two, preventing water or dust from entering the base 110 and damaging the internal electronic components. In practical applications, the first interface 1144 has an internal thread, and the washing drum 120 has an external thread, allowing for a threaded connection. In addition, the second interface 1146 is inserted into the base 112 to facilitate a sealed connection between the second connection port and the base 112. To ensure a stable connection between the top cover 114 and the base 112, a connecting post can be set inside the base 112, and screws can be connected to the connecting post on the top cover 114.

[0044] In optional embodiments of this application, such as Figure 1 As shown, the cleaning cylinder 120 is made of transparent material, and a cylinder cover 160 is provided at the end of the cleaning cylinder 120 away from the base 110.

[0045] Specifically, the transparent drum 120 allows users to clearly see the washing process, increasing convenience and enjoyment. For example, users can determine whether to extend the washing time based on the degree of soiling of the clothes, or observe the dissolution of detergent to decide whether to add more detergent. This visual design meets users' need for control over the washing process and enhances the user experience. The drum lid 160 effectively prevents clothes from splashing out during the washing process, avoiding safety hazards caused by clothes being thrown out, such as getting tangled in rotating parts or causing user injury. At the same time, the drum lid 160 has a certain degree of noise reduction during the washing process, reducing the impact of the mini washing machine 100's operating noise on the user's living environment and creating a quieter and more comfortable usage environment. When the mini washing machine 100 is not in use, the drum lid 160 can prevent dust and debris from entering the drum 120, preventing bacterial growth. Especially for situations where it is not used for a long time, the drum lid 160 can keep the inside of the drum 120 clean, eliminating the need to clean the drum 120 again before the next use, allowing for direct washing operations and saving users time and effort.

[0046] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
