[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0020] like Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, an embodiment of the present invention provides a mini washing machine 100, comprising: a base 110, and a washing drum 120 detachably connected to the base 110, wherein a drive motor 130 is provided in the base 110, a pulsator 140 is rotatably connected to the base 110, and the pulsator 140 is transmission-connected to the drive motor 130; the washing drum 120 is used to place laundry, and the washing drum 120 can be sealed to the base 110; an electrolysis module 150 is further provided on the base 110, and the electrolysis module 150 is located on one side below the pulsator 140, and the electrolysis module 150 is used to generate hypochlorous acid by electrolysis.

[0021] Specifically, the base 110, serving as the foundation of the mini washing machine 100, houses a drive motor 130, which provides the power for the mini washing machine 100 to wash clothes. A pulsator 140 is rotatably connected to the base 110 and is in transmission connection with the drive motor 130. When the drive motor 130 is in operation, it drives the pulsator 140 to rotate. The rotation of the pulsator 140 generates a water flow that flushes and rubs the laundry within the washing tub 120, achieving the desired cleaning effect. Furthermore, the detachable connection between the washing tub 120 and the base 110 allows the user to remove the washing tub 120 for separate cleaning after washing, preventing dirt from remaining inside the tub and breeding bacteria, ensuring a hygienic wash cycle for the next load. The base 110 also houses an electrolysis module 150, located to the side below the pulsator 140. The electrolysis module 150's primary function is to electrolytically generate hypochlorous acid, a highly oxidizing chemical with effective sterilization and disinfection capabilities. During the washing process, electrolysis module 150 uses the water in the washing machine as an electrolyte to generate hypochlorous acid through an electrolytic reaction, which enhances the cleaning effect. This hypochlorous acid can also kill bacteria, mites, and other microorganisms on clothing, thereby compensating for the lack of sterilization and disinfection capabilities of traditional mini washing machines 100 due to their inherent space and structural limitations. It should be noted that to ensure the content of hypochlorous acid generated during electrolysis, a small amount of salt can be added to the washing drum 120, or a laundry detergent containing salt can be used.

[0022] The mini washing machine 100 provided in this embodiment of the present application utilizes a transmission connection between a drive motor 130 and a pulsator 140, providing stable power to the pulsator 140. This ensures that the pulsator 140 continuously and efficiently agitates the water and clothing during the wash cycle, achieving excellent cleaning results. This simple and reliable structural design meets the requirements of the mini washing machine 100 for compactness and practical functionality. Furthermore, the sealed connection between the washing drum 120 and the base 110 enhances the safety and stability of the washing machine's operation. Furthermore, the detachable washing drum 120 facilitates deep cleaning, maintains a sanitary environment within the washing machine, and further extends the machine's service life. The electrolytic module 150 provided in the base 110 generates hypochlorous acid, which effectively kills various bacteria and mites on clothing, thereby enhancing the sterilization and disinfection effect during washing. This provides adequate hygiene for mothers washing their baby's clothes and women washing their underwear, among other applications. Compared to traditional washing machines, this product significantly enhances its functionality and practicality, thereby improving the user experience.

[0023] When the impeller 140 is connected to the drive motor 130 in transmission, the output shaft of the drive motor 130 can be extended from the base 110, and the impeller 140 can be clamped with the output shaft to achieve the required transmission connection, thereby simplifying the connection form.

[0024] like Figure 3 As shown, the electrolytic module 150 includes a first electrode 152 and a second electrode 154 that are spaced apart. The first electrode 152 and the second electrode 154 are fixedly connected to the base 110 respectively.

[0025] Specifically, the first and second electrodes 152, 154 are fixed to the base 110, ensuring their stability during operation. This prevents the electrodes from shifting due to vibrations of the mini washing machine 100, which could affect the electrolysis effect. In actual use, one of the first and second electrodes 152, 154 is connected to the positive terminal of a power supply, while the other is connected to the negative terminal of the power supply, to facilitate electrolysis during the mini washing process. Furthermore, the first and second electrodes 152, 154 are spaced apart to prevent short circuits during use, ensuring safety.

[0026] like Figure 4 As shown, the first electrode 152 includes a first connecting portion 1522 and a plurality of first pole pieces 1524 connected to the first connecting portion 1522, the first pole piece 1524 is arc-shaped, and the first pole piece 1524 extends 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 pole pieces 1544 connected to the second connecting portion 1542, the second pole pieces 1544 are arc-shaped, and the first pole piece 1524 extends outward on both sides of the first connecting portion 1522; the first pole pieces 1524 and the second pole pieces 1544 are alternately arranged radially along the circumference.

[0027] Specifically, the first electrode 152 and the second electrode 154 adopt an arc-shaped structure, which significantly increases the contact area with the laundry water. During the electrolysis process, the larger the contact area, the more complete the electrolysis reaction, which can more effectively convert electrical energy into chemical energy and produce more hypochlorous acid. The first electrode 1524 and the second electrode 1544 are arranged alternately along the radial direction of the circumference. This not only increases the contact area between the electrodes and the liquid, but also reduces the space occupied by the first electrode 152 and the second electrode 154. While achieving the requirements of increasing the contact area and improving the electrolysis efficiency, it also fully considers the limited space of the mini washing machine 100. Through the reasonable shape design and arrangement, the functions of the first electrode 152 and the second electrode 154 are optimized without occupying too much space, meeting the requirements of the mini washing machine 100 for structural compactness.

[0028] like Figure 2 As shown, an annular edge 1142 is provided on the base 110, and the impeller 140 includes a circular bottom plate 142 and an annular side wall 144 provided on the edge of the circular bottom plate 142. There is a gap between the annular side wall 144 and the inner wall of the annular edge 1142, and the height of the impeller 140 is higher than the height of the annular edge 1142.

[0029] Specifically, there is a gap between the annular sidewall 144 and the inner wall of the annular rim 1142. The existence of this gap is to ensure that the impeller 140 does not interfere with the annular rim 1142 during rotation, ensuring that the impeller 140 can rotate freely and smoothly, and preventing the laundry from accidentally getting stuck under the impeller 140, thereby ensuring reliability during the washing process. In addition, the design of the impeller 140 being higher than the annular rim 1142 allows the impeller 140 to stir the water flow more effectively during rotation. The taller impeller 140 can drive the water flow to form a larger range and stronger circulation, better disperse the clothes in the water flow, increase the contact opportunities between the clothes and the water flow and detergent, thereby improving the cleanliness and washing effect of the laundry. In addition, the circular bottom plate 142 is also provided with a plurality of smooth protrusions to enhance the effect of stirring the water flow, thereby improving the washing effect.

[0030] like Figure 3 and Figure 7 As shown, the base 110 is also provided with an annular flange 116 located on one side of the annular edge 1142, and the electrolytic module 150 is arranged in the annular flange 116. The annular flange 116 includes a first edge 1162 and a second edge 1164 connected to each other. The annular edge 1142 is flush with the height of the first edge 1162 and is connected to form a closed area. The second edge 1164 is located on the inner side of the annular edge 1142, and the height of the second edge 1164 is lower than the height of the annular edge 1142 to avoid the impeller 140.

[0031] Specifically, the annular lip 116 provides a relatively stable and safe working environment for the electrolysis module 150. During the laundry process, the water flow is subject to significant impact and fluctuations. If the electrolysis module 150 is directly exposed to the water flow, the impact may cause the first electrode 152 or the second electrode 154 to loosen or become damaged, or otherwise affect the normal electrolysis reaction. The annular lip 116 effectively reduces the impact of external factors on the electrolysis module 150, ensuring its normal operation and improving its service life and reliability. Furthermore, the enclosed area formed by the abutment between the annular lip 116 and the annular rim 1142 facilitates a smoother transition between the two, ensuring overall smoothness and reducing wear on the laundry. The design of the second edge 1164 being lower than the annular rim 1142 cleverly resolves the spatial conflict between the rotation of the pulsator 140 and the annular lip 116. When the pulsator 140 rotates at high speed, sufficient space is required to ensure its smooth operation. If the annular flange 116 is too high, it may hinder the rotation of the pulsator 140 and affect the normal operation of the washing machine. This avoidance design ensures that the pulsator 140 can rotate freely while also ensuring that the annular flange 116 protects the electrolytic module 150, achieving a reasonable and coordinated structural design.

[0032] like Figure 3 and Figure 5 As shown, in an optional embodiment of the present application, the base 110 includes a base body 112 and a top cover 114 connected to the base body 112, the first electrode 152 and the second electrode 154 are arranged on the top cover 114, the first electrode 152 is connected to the first positioning member 156, and the second electrode 154 is connected to the second positioning member 158, and the first positioning member 156 and the second positioning member 158 respectively pass through the top cover 114 and extend into the base body 112.

[0033] Specifically, the first electrode 152 and the second electrode 154 are mounted on the top cover 114, with a positioning member extending through the top cover 114 into the interior of the base 112. This mounting method provides dual securing for the electrodes. During operation, the mini washing machine 100 may experience vibration and shaking. If the first and second electrodes 152, 154 are not securely mounted, they can easily shift or even fall off, affecting the normal operation of the electrolysis module 150. This mounting structure effectively resists the effects of external vibrations and other factors, ensuring that the first and second electrodes 152, 154 are always correctly positioned, ensuring the stable electrolysis reaction and thus the reliability of the washing machine's sterilization function.

[0034] like Figure 6 and Figure 7As shown, in another optional embodiment of the present application, the base 110 includes a base body 112 and a top cover 114 connected to the base body 112, the top cover 114 is provided with a accommodating cavity 118 extending into the base body 112, the first electrode 152 and the second electrode 154 are arranged at the bottom of the accommodating cavity 118, the first electrode 152 is connected to a first positioning member 156, the second electrode 154 is connected to a second positioning member 158, the first positioning member 156 and the second positioning member 158 respectively pass through the accommodating cavity 118 and extend into the base body 112.

[0035] Specifically, a receiving cavity 118 is provided on the top cover 114 to accommodate the first electrode 152 and the second electrode 154, providing an independent, neatly arranged installation space for the first electrode 152 and the second electrode 154. Compared to directly installing the first electrode 152 and the second electrode 154 on the top cover 114, while maintaining the aforementioned advantages, the receiving cavity 118 can also be filled with sufficient laundry water. This minimizes the impact on the contact between the first electrode 152 and the second electrode 154 and the water when the pulsator 140 rotates, thus ensuring reliable electrolysis.

[0036] It should be noted that the first positioning member 156 and the second positioning member 158 can be fixed with bolts and nuts provided on the back of the top cover 114, wherein the nuts can be directly hot-melted on the top cover 114 to facilitate the cooperation with the first positioning member 156 and the second positioning member 158. It should also be noted that in order to ensure the sealing of the connection between the first positioning member 156 and the second positioning member 158 and the top cover 114, a sealing gasket can be provided at the corresponding position of the top cover 114 to prevent the laundry water from leaking into the base 110. At the same time, the first positioning member 156 and the second positioning member 158 extend into one end of the base 112 for connecting the positive and negative poles of the power supply, and can serve as both positioning members and conductive members, which is conducive to improving the compactness of the connection and simplifying the connection form.

[0037] like Figure 3 and Figure 6 As shown, a hollow cover 159 is further provided in the annular ridge 116 , and a holding portion 1166 is provided in the annular ridge 116 , and the hollow cover 159 is held at the holding portion 1166 .

[0038] Specifically, the hollow cover 159 provides a protective barrier for the electrolysis module 150. During the washing process, debris (such as hair, fibers, etc.) may fall onto clothing. If this debris enters the electrolysis module 150, it may become entangled with the first electrode 152 or the second electrode 154, affecting the electrolysis reaction and even causing faults such as electrode short circuits. The hollow cover 159 blocks debris from entering, while its hollow design ensures smooth water flow, enabling the electrolysis module 150 to function properly, providing excellent protection and ventilation. Furthermore, the hollow cover 159 is mounted within the annular flange 116 using a clip-on design. When the electrolysis module 150 needs to be inspected, maintained, or cleaned, the hollow cover 159 can be easily removed, making the operation simple and quick. This facilitates the timely removal of debris from the hollow cover 159 and the surrounding area of ​​the electrolysis module 150, keeping the electrolysis module 150 clean and in good working condition, thereby extending the service life of the electrolysis module 150.

[0039] In an optional embodiment of the present application, a battery is provided in the base body 112 , and the first positioning member 156 , the second positioning member 158 and the drive motor 130 are electrically connected to the battery respectively.

[0040] This configuration eliminates the need for an external power outlet for the mini washing machine 100. This allows users to use the mini washing machine 100 in locations without power outlets (e.g., outdoors, in corners of rooms without suitable outlets), significantly expanding its use cases. Whether traveling, camping, or in other special environments, the mini washing machine 100 can be conveniently used for laundry, enhancing both product practicality and user experience.

[0041] like Figure 3 As shown, the outer ring of the top cover 114 is provided with a first interface 1144 and a second interface 1146 that protrude in both directions. The first interface 1144 is threadedly connected to the cleaning cylinder 120. A sealing gasket is also provided on the top cover 114, which is supported between the cleaning cylinder 120 and the top cover 114. The second interface 1146 is plugged into the base body 112, and a sealing ring is provided between the second interface 1146 and the base body 112.

[0042] Specifically, the first interface 1144 is threadedly connected to the washing barrel 120. This threaded connection method can achieve a tight fixation between the washing barrel 120 and the top cover 114, and is convenient for the user to perform disassembly and installation operations. A sealing gasket is also provided on the top cover 114, which is supported between the washing barrel 120 and the top cover 114, further enhancing the sealing of the connection part and preventing water from leaking from the connection gap during the washing process. The second interface 1146 is plugged into the base 112, and a sealing ring is provided between the second interface 1146 and the base 112. The sealing ring ensures the sealing of the connection between the two, preventing water or dust from entering the interior of the base 110 and damaging the internal electronic components. In actual applications, the first interface 1144 is provided with an internal thread, and the washing barrel 120 is provided with an external thread so that they can be connected in the form of a threaded connection. In addition, the second interface 1146 is plugged into the base body 112 to facilitate the sealed connection between the second connection port and the base body 112. In order to ensure a stable connection between the top cover 114 and the base body 112, a connecting column can be set in the base body 112, and screws can be connected to the connecting column on the top cover 114.

[0043] In an optional embodiment of the present application, Figure 1 As shown, the cleaning cylinder 120 is made of a transparent material, and a cylinder cover 160 is provided at one end of the cleaning cylinder 120 away from the base 110 .

[0044] Specifically, the transparent washing drum 120 allows users to clearly see the washing process, increasing convenience and enjoyment. For example, users can determine whether to extend the wash time based on the degree of soiling of the clothes or observe the dissolution of the detergent to determine whether to add more detergent. This visual design satisfies users' need for control over the washing process and enhances the user experience. The drum cover 160 effectively prevents clothes from splashing during the wash cycle, avoiding safety hazards such as entanglement in rotating components and possible injury. Furthermore, the drum cover 160 provides a certain degree of insulation against noise generated during the wash cycle, 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 user environment. When the mini washing machine 100 is not in use, the drum cover 160 prevents dust and debris from entering the washing drum 120, preventing the growth of bacteria. Especially for long periods of non-use, the drum cover 160 keeps the interior of the washing drum 120 clean. The next time the washing drum 120 is used, there is no need to clean it again; washing can proceed directly, saving users time and effort.
