It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0032] In the description of the utility model, it is necessary to understand that the orientation or positional relationship indicated by the terms "longitudinal", "radial", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is the orientation or positional relationship based on the drawings shown, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as a limitation on the utility model. In the description of the utility model, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0033] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0034] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 6 , an embodiment of the utility model provides a swing type electric brush, including swing motor 1, brush assembly 2, anti-splashing cover 3 and handle 4 provided with internal space 41;The swing motor 1 is installed in the internal space 41 and is connected to the brush assembly 2, for driving the brush assembly 2 to swing;Understandably, the internal space 41 is also provided with a battery and a control panel, and a switch button is arranged on the outer wall of the shell, and the battery, the switch button and the swing motor 1 are electrically connected with the control panel;The brush assembly 2 can be located at the side of the handle 4, or can be located in front of the handle 4.

[0035] The anti-splashing cover 3 includes cover body 31 provided with containing space 33 and a plurality of blocking bristles 32 installed on the cover body 31, and the cover body 31 can be detachably installed on the handle 4, and the brush assembly 2 is located in the containing space 33. Understandably, the blocking bristles 32 are arranged around the containing space 33;The cover body 31 can be detachably installed on the handle 4 through a clamping structure, a plug-in structure or the like;The brush assembly 2 can swing in the containing space 33, and the blocking bristles and the brush assembly 2 have a certain gap.

[0036] In this invention, the oscillating motor 1 is installed in the internal space 41 of the handle 4 and connected to the brush assembly 2. The oscillating motor 1 can drive the brush assembly 2 to oscillate at a high frequency. The bristles of the brush assembly 2 oscillate and bounce back and forth on the surface of the item being cleaned. The brush assembly 2 allows the cleaning liquid to quickly foam and drive the foam to splash. The splashed cleaning liquid can penetrate into the crevices of the surface of the item being cleaned, washing away the stains in the crevices. Furthermore, the contact between the bristles of the brush assembly 2 and the surface of the item being cleaned is oscillating, which causes less damage to the item being cleaned compared to rotational friction. When the surface of the item being cleaned has fibers or hair, the high-frequency oscillation of the brush assembly 2 causes the bristles of the brush assembly 2 to penetrate into the fibers or hair and drive the fibers or hair to oscillate together. Therefore, the oscillating electric brush does not get tangled in fibers or hair during cleaning, improving the safety of the oscillating electric brush.

[0037] In addition, the splash guard 3 includes a cover 31 with a receiving space 33 and a plurality of blocking bristles 32 mounted on the cover 31. The cover 31 is detachably mounted on the handle 4. The brush assembly 2 oscillates at a high frequency in the receiving space 33. The cleaning liquid stirred up by the bristles of the brush assembly 2 splashes in all directions, thereby giving the cleaning liquid a greater impact force, which can penetrate into the crevices of the surface of the item being cleaned, thus improving the cleaning ability of the oscillating electric brush. The blocking bristles 32 prevent foam from splashing outside. The cover can also prevent the bristle base of the high-frequency oscillating brush assembly 2 from touching the item being cleaned or the human body.

[0038] In one embodiment, such as Figure 2 and Figure 3 ,as well as Figure 6 and Figure 7 As shown, the handle 4 is also provided with a shaft hole 42 communicating with the internal space 41. The oscillating electric brush also includes a waterproof cover 5 with a first through hole 51 and a pressure plate 6 with a second through hole 61. The pressure plate 6 is installed on the handle 4 and is used to press the waterproof cover 5 onto the handle 4. The end of the waterproof cover 5 away from the handle 4 passes through the second through hole 61. Understandably, the splash guard 3 can be made of silicone material. The pressure plate 6 and the handle 4 can be connected by fasteners such as screws and bolts. The handle 4 is provided with blind holes for the fasteners to be screwed in. The bottom of the waterproof cover 5 is pressed onto the handle 4 by the pressure plate 6, and the top of the waterproof cover 5 extends out from the second through hole 61.

[0039] The output shaft 11 of the oscillating motor 1 passes sequentially through the shaft hole 42 and the first through hole 51 and then connects to the brush assembly 2. In this embodiment, the waterproof cover 5 is sleeved on the output shaft 11 of the oscillating motor 1, so that the waterproof cover 5 can prevent external moisture from entering the internal space 41 through the shaft hole 42, thus ensuring the waterproof performance of the oscillating electric brush.

[0040] In one embodiment, such as Figure 2 and Figure 3 ,as well as Figure 6 and Figure 7 As shown, the handle 4 is provided with a mounting groove 43, and the shaft hole 42 is provided on the bottom wall of the mounting groove 43; the edge of the mounting groove 43 is provided with a first annular groove 44, and the bottom wall of the mounting groove 43 is also provided with a first annular protrusion 45 surrounding the shaft hole 42; the waterproof cover 5 is inserted into the first annular groove 44. It can be understood that the edge of the waterproof cover 5 is inserted into the first annular groove 44 (that is, the pressure plate 6 presses the edge of the waterproof cover 5 into the first annular groove 44), and a water storage tank can be formed between the first annular protrusion 45 and the edge of the waterproof cover 5. Even if a small amount of water enters the mounting groove 43, the small amount of water will be stored in the water storage tank and will not enter the internal space 41 through the shaft hole 42. A sensor can be set here to detect the water entering, thereby terminating or preventing the electric brush from working, preventing further water leakage, and further improving the waterproof level of the oscillating electric brush.

[0041] In one embodiment, such as Figure 2 and Figure 3 ,as well as Figure 6 and Figure 7 As shown, the waterproof cover 5 includes an annular outer sleeve 52, a transition sleeve 53, and a sealing inner sleeve 54 with the first through hole 51, all coaxially connected in sequence.

The pressure plate 6 presses the annular outer sleeve 52 into the first annular groove 44. The sealing outer sleeve extends outward toward the handle 4, and the top of the sealing inner sleeve 54 is fitted onto the output shaft 11 of the oscillating motor 1. In this embodiment, the annular outer sleeve 52, the transition sleeve 53, and the sealing inner sleeve 54 all have the technical effect of sealing the shaft hole 42, further improving the waterproof rating of the oscillating electric brush. Furthermore, during the high-frequency oscillation of the sealing inner sleeve 54 driven by the output shaft 11 of the oscillating motor 1, the transition sleeve 53 is wave-shaped, extending the length of the waterproof membrane and providing a better buffering effect, thereby extending the service life of the waterproof cover 5.

Understandably, the second annular protrusion 541 is inserted into the second annular groove 111, thereby ensuring the stability of the sealing inner sleeve 54 sleeved on the output shaft 11 of the swing motor 1.

[0043] In an embodiment, as shown in Figure 2 and Figure 3 , and Figure 6 and Figure 7 , the first through hole 51 is a tapered through hole; from one end of the handle 4 close to the brush assembly 2, the inner diameter of the tapered through hole gradually decreases. Understandably, the inner wall of the first through hole 51 is an inclined wall, and the output shaft 11 of the swing motor 1 will not touch the inner wall when swinging or twisting, and the involvement of the transition sleeve 53 is buffered (that is, the smaller the inner diameter, the smaller the swing at this point when twisting, and the swing L=arc angle α*radius r).

[0044] In an embodiment, as shown in Figure 2 and Figure 3 , and Figure 6 and Figure 7 , the application of the high-frequency swing of the waterproof cover 5 will gradually age, and it is a consumable part.
