It can be understood that the stain removing device can be used together with the washing machine. During the cleaning of the laundry 7, the user can put the stained area of the laundry 7 into the drain groove 81, and the water sprayed by the spray assembly 5 can be temporarily stored. In the drain groove 81, thereby, it is ensured that there is sufficient water when the laundry 7 is partially washed. And when the water level reaches a certain height, the water in the drain tank 81 can be discharged into the washing tub of the washing machine by siphoning.

 As shown in FIG. 1, a shower assembly 5 may include: a water conduit 51 and a spray head 52, in accordance with an embodiment of the present invention.

 Specifically, one end of the water conduit 51 is connected to the water source, and the other end passes through the brush 3 and is extended by the brush head 31. In other words, one end of the water conduit 51 can be connected to the water supply device to partially flush the laundry 7 with water, and the other end is extended by the brush head 31 of the brush 3 to supply water to the laundry 7 directly corresponding to the bristles of the brush head 31. on. The head 52 may be provided at the other end of the water conduit 51 and partially opposed to the garment 7 positioned on the positioning member 8. Thereby, the laundry 7 can be partially flushed by the head 52. As shown in Fig. 1, according to an embodiment of the present invention, in order to improve the flushing efficiency, the other end of the water conduit 51 is projected from the center of the head 31.

As shown in FIG. 1, according to an embodiment of the present invention, the local stain removing device may further include: The transfer member 2 can be connected to the brush 3 and the vibrator 1 respectively to transmit the vibration of the vibrator 1 to the brush 3. The vibrator 1 can generate a vibration of a predetermined frequency, which is transmitted to the brush 3 through the transmission member 2, and the brush 3 generates vibration of a predetermined frequency. The vibrating brush is brought into contact with the stained area on the part of the garment 7, whereby the stain on the laundry can be removed by the vibration of the brush 3 and the chemical action of the detergent on the stain.

 As shown in FIG. 1, according to an embodiment of the present invention, the partial stain removing device may further include an outer casing

6. The vibrator 1 can be disposed in the outer casing 6, the brush 3 is located outside the outer casing 6, and the vibrator 1 and the brush 3 are connected by the transfer member 2. Thereby, the vibrator 1 is disposed in the outer casing 6, which can protect the vibrator 1 from accidental contact with water, thereby causing the vibrator 1 to be accidentally damaged.

Thereby, even if the brush 3 splashes the washing liquid at the time of washing, the casing 4 can prevent the washing liquid from splashing out of the stained area.

 As shown in Fig. 1, according to an embodiment of the present invention, the bottom end of the casing 4 is connected to the open end of the drain groove 81 of the positioning member 8. Thereby, it is possible to cause the entire washing liquid to flow into the drain tank 81 to prevent the washing liquid from splashing outward. According to an embodiment of the present invention, one end of the outer casing 6 may be configured as a handle portion 61. Thereby, it is convenient for the user to carry out the stain removal treatment of the laundry by holding the local stain removing device.

 According to the partial stain removing device of the embodiment of the invention, the vibrator 1 can generate a vibration of a predetermined frequency which is transmitted to the brush 3 through the transmitting portion 2, and the brush 3 generates vibration of a predetermined frequency. The vibrating brush 3 is brought into contact with the stained area of the garment 7 (fabric), and the stain on the fabric is removed by the vibration of the brush 3 and the chemical action of the detergent on the stain.

 The spray assembly can be sprayed with water to wet the local stain area of the garment before the vibrator 1 is turned on. After the washing is completed, turn on the spray unit 5 and spray the water to wash the stain.

 The positioning member 8 has a drain groove 81, and the user can place the stained area of the laundry 7 into the drain groove 81, and the water sprayed from the spray unit 5 is temporarily stored in the drain groove 81 to ensure sufficient water during washing. When the water level reaches a certain height, the water in the drain tank 81 can be discharged into the washing tub by siphoning.

 The function of the casing 4 may be that the brush 3 will splash the washing liquid during washing, and the casing 4 can prevent the washing liquid from splashing out of the stained area.

 The operation of the partial stain removing device according to an embodiment of the present invention will be described below with reference to the drawings.

As shown in Fig. 1, the user can apply the detergent to the stain on the portion of the garment 7, while placing the stain portion above the drain groove 81, and then aligning the portion of the brush 3 with the stain on the garment 7. The spray assembly 5 is then activated to inject a certain amount of water onto the stain of the garment 7. Then, the vibrator 1 is activated, and the vibrator 1 generates vibration of a predetermined frequency, and the vibration is transmitted to the brush 3 through the transmission portion 2. The mechanical vibration of the brush 3 is very good for the water and detergent on the fabric. The strong agitation action forms a high concentration of the washing liquid, and the vibration of the brush 3 has a mechanical peeling force on the stain on the laundry, which is advantageous for removing the stain on the laundry. After the washing process is finished, the detergent on the fabric needs to be rinsed off. At this time, the shower assembly 5 is turned on, or the vibrator 1 is turned on at the same time to vibrate the brush 3, and a water flow is generated to flush the washing liquid on the laundry into the drain tank 81, and discharge the sewage into the washing machine drain through the drain groove 81, so that the clothes The stains on the stains are washed away and the entire garment is not washed in the washing machine.
