The round brush of the invention has the advantages of energy saving and water saving, good flushing effect, car body protection, long service life, etc., and is widely used in vehicle cleaning.

However, the water outlet under such a structure is very uneven. Moreover, in order to ensure the strength of the cleaning disc, the water pressure of the water inlet should not be particularly high, otherwise the high water pressure will cause the cleaning disc to be distorted, deformed or even damaged, which will affect the service life of the entire cleaning device. The cleaning tray needs to be cleaned after long-term use, and the cleaning tray itself in the prior art also has dead ends, and must be disassembled for cleaning, which is very inconvenient. Similarly, repeated disassembly and washing will also affect the service life of the cleaning equipment.

Contents of the invention

The present invention provides an electric cleaning device, especially a cleaning tray used for this type of electric cleaning device, aiming to solve the problems of uneven water output and small water output adjustment interval of the cleaning device in the prior art. It is convenient to clean the washing plate itself.

In this regard, a cleaning tray described in the present invention includes an outer brush tray, and the outer brush tray is provided with a concave cavity for accommodating the inner brush tray; the bottom of the concave cavity is circumferentially distributed at least two first A water outlet channel, the first water outlet channel extends from the edge of the bottom of the concave cavity toward the center, and a second water outlet channel for cleaning the concave cavity is provided between two adjacent first water outlet channels. This design increases the flow area of the water in the cavity, ensuring that every inch of the cavity can be washed by the water when it rotates.

Preferably, the cavity includes a bottom surface and a side wall, and the second water outlet channel is arranged on the bottom surface of the cavity and is located at a connection between the bottom surface and the side wall. After the second water outlet channel is provided, the water outlet space on the bottom of the concave cavity is increased, and at the same time, the bottom of the concave cavity will not be damaged when being impacted by the water flow.

Preferably, an inner rib is formed on one side of the first water outlet channel, the inner rib is close to the first water outlet channel, and the length of the inner rib is longer than the length of the first water outlet channel.

Preferably, the first water outlet channel is a single water outlet channel or a plurality of continuous water outlet holes; the second water outlet channel is also a single water outlet channel or a plurality of continuous water outlet holes. The first water outlet channel and the second water outlet channel can actually be a single curved water tank, or a plurality of water outlet holes evenly arranged, and the water outlet holes can be circular or long strips with arc corners. In fact, it works best as a strip-shaped spout.

Preferably, the first water outlet channel and the second water outlet channel are connected to each other. The interconnection ensures that two water outlet channels can be completed in one process during production, which reduces the production cost.

Preferably, the outer brush plate is further provided with a plurality of arc-shaped pieces, and the projection of the arc-shaped pieces in the vertical direction circumscribes the circular concave cavity. The curved piece is used to increase the overall strength of the outer brush plate, and is usually arranged on the inner surface of the outer brush plate.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

As shown in FIGS. 1-4 and 7 , the cleaning tray described in the present invention includes an outer brush tray 1 and an inner brush tray 2 . The outer brush plate 1 has two surfaces, namely an outer surface and an inner surface, wherein the outer surface is the side that matches and contacts the inner brush plate 2 and faces downward during actual use.

The outer brush plate 1 is provided with a concave cavity for accommodating the inner brush plate; at least two first water outlet channels 6 are distributed at the bottom of the concave cavity 3 at intervals in the circumferential direction, and the first water outlet channels 6 are formed by the concave cavity 3 The edge of the bottom of the body extends toward the center, and a second water outlet channel 8 for cleaning the concave cavity 3 is provided between two adjacent first water outlet channels 6 . The second water outlet channel 8 also has the effect of additionally increasing the water flow without reducing the strength of the bottom of the concave cavity 3 .

The cavity 3 includes a bottom surface and a side wall 15 , and the second outlet channel 8 is arranged on the bottom surface of the cavity 3 and is located at the junction of the bottom surface and the side wall 15 . Viewed from the inner side of the outer brush plate, after the water flow enters the inner side of the outer brush plate 1, the water flow rotates between the brush plates through the rotation of the outer brush plate 1 and the inner brush plate 2. The concave cavity 3 is provided with an outer shaft connection hole; the outer shaft connection hole on the concave cavity 3 is the center of the circle, and there are 12 first water outlet channels 6, between two adjacent first water outlet channels 6, along the edge of the concave cavity, there are The second water outlet channel 8; bristle fixing holes 13 are provided on the outstretched part; each bristle fixing hole 13 is correspondingly fixed with a bundle of bristles.

The first water outlet channel 6 and the second water outlet channel 8 in this embodiment are strip-shaped water outlet grooves, and are connected to each other front and back. This is conducive to reducing the number of processes during production.

One side of the first water outlet channel 6 is provided with an inner rib 7 , the inner rib 7 is close to the first water outlet channel 6 , and the length of the inner rib 7 is greater than the length of the first water outlet channel 6 . In order to better control the water flow during use, the inner rib 7 of the concave cavity 3 is arc-shaped, and the length of the inner rib 7 is 3/4-2/3 of the diameter of the circle where the concave cavity 3 is located. It should be noted that inner retaining ribs 7 are provided in the concave cavity 3 on the inner surface and the outer surface of the outer brush plate 1 .

It can be seen in the figure that on the inner surface of the outer brush plate 1 , corresponding blocking strips 14 are provided above the first water outlet channel 6 and the second water outlet channel 8 . The blocking strip 14 is arranged in a strip shape, and is usually arranged on the top of the inner rib 7 and the side wall 15 in the inner surface of the outer brush tray 1 . The blocking strip 14 can fully cover the first water outlet channel 6 and the second water outlet channel 8 . The water flow enters the outer brush tray 1 from the inner side. If there is no blocking bar 14, some water flow may directly flow out from the first water outlet channel 6 or the second water outlet channel 8 without sufficient rotation. In this way, dripping water will appear during use, which will greatly affect the use effect. Increased barrier bar 14 has just avoided such situation from taking place.

In this way, when working, under the centrifugal action brought by the rotation and the blocking effect of the inner rib 7, part of the water flows out from the first water outlet channel 6, while the other part is absorbed by the side wall between the concave cavity 3 and the outstretched part. 15 blocks, and flows out from the second water outlet channel 8.

A plurality of arc-shaped pieces 5 are arranged on the outstretched part of the outer brush plate 1 , and the projections of the arc-shaped pieces 5 circumscribe the circular cavity 3 . The arc-shaped sheet 5 is used to improve the overall strength of the outer brush plate 1 . The bristle fixing holes 13 are distributed circularly. This ensures that the configurations of the outlet water and the wash pan match each other. The outstretched portion is provided with four ring-shaped bristle fixing holes 13 . Four annularly distributed bristle fixing holes 13 completely cover the entire surface of the outstretched portion. Actually, for different types of cleaning equipment, the installer can selectively fix the bristles in the designated bristle fixing holes 13, so as to achieve different effects.

As shown in Fig. 5 and Fig. 6, the inner brush disc 2 includes a disc body, the radius of the disc body is the same as the cavity 3 of the outer brush disc 1, and bristle fixing holes 13 are evenly arranged on the disc body, and the disc body The center of the body is provided with an inner shaft clamping block 9, and the inner shaft clamping block 9 is used for matching and positioning with the inner shaft 12.

The outer brush plate 1 is fixed on the outer shaft 11 , the inner brush plate 2 is fixed on the inner shaft 12 through the connecting piece 10 , and the inner brush plate 2 is installed in a position corresponding to the cavity 3 of the outer brush plate 1 .

In some other embodiments, any or all of the first water outlet channel 6 or the second water outlet channel 8 is set as a plurality of water outlet holes arranged uniformly, which can also increase the water output while ensuring the strength of the brush plate. effect, but the processing cost is slightly higher and the relative water output is not as good as the strip-shaped water outlet when used. The actual opening volume of the first water outlet channel 6 is inversely proportional to its number, and should not exceed 24 channels at most. Too many first water outlet channels 6 will affect the overall strength of the outer brush plate 1 .

Regardless of which of the above implementations, in actual use, it is only necessary to install the cleaning disc on the corresponding cleaning equipment, as shown in Figure 7 and Figure 8, the outer brush disc 1 and the inner brush disc 2 are respectively fixed on different shafts , but after the fixing is completed, the outstretched part of the outer brush plate 1 and the inner brush plate 2 are on the same plane. The outer brush disc 1 and the inner brush disc 2 rotate in opposite directions synchronously during use. The cleaning equipment in the prior art uses a single brush disc or multiple brush discs to rotate in the same direction, which causes the reaction force during cleaning to cause displacement of the entire cleaning device. Instability to control can occur even with heavier cleaning equipment. However, the inner brush disc 2 and the outer brush disc 1 of the present invention rotate in opposite directions synchronously, and the reaction forces produced when the two contact with the ground during cleaning cancel each other out, which makes the whole cleaning disc extraordinarily stable. Especially in conjunction with the sufficient water outlet of the first water outlet channel 6 or the second water outlet channel 8, the bristles are sufficiently wetted, further reducing the friction during the plotting process. During the rotation process, the water in the cleaning equipment is evenly distributed in the concave cavity 3 under centrifugal action, and the water flow in the space formed between the adjacent internal retaining ribs 7 forms a small vortex, and finally the water flows from the first water outlet channel 6 and the second water outlet channel. out of channel 8. The relatively high linear velocity of the outstretched part makes the wetting area corresponding to the thrown water flow larger, and at the same time, the amount of water per unit area decreases. The thrown water flow is easier to wet the bristles first, ensuring the surface of the object to be cleaned after use. Not easy to produce stagnant water.

Not only that, such a structure can also realize the rotation of the two brush plates in the same direction and at different speeds. No matter the speed is high or low, it can ensure uniform water discharge and ensure the use effect of the cleaning disc.

The invention is mainly used for electric cleaning equipment, such as sweepers or scrubbers. These electric cleaning devices have different requirements for water output according to actual needs. For a relatively clean floor, it is only necessary to control the floor so that it is just wet and easy to clean, and there will be no water accumulation after cleaning. The brush plate provided by the present invention can also ensure uniform and uninterrupted water discharge when the water flow is small, and the actual water discharge is limited, which just meets such an effect. However, for some environments where dirt is deposited, a larger water output is required. At this time, it is only necessary to increase the water output at the water outlet channel. The separate setting of the first water outlet channel 6 and the second water outlet channel 8 can ensure that after the water pressure is increased, the overall strength of the entire brush plate is sufficient to avoid deformation or rupture of the brush plate due to excessive water pressure. It is also more stable to use.

The cleaning tray also needs to clean itself after use. During the self-cleaning process of the cleaning tray, it is only necessary to add a small amount of water with cleaning agent when entering the water, and rotate at a higher speed. Under the action of high-speed rotation, the water flow remains in the cleaning tray for a long time under the action of centrifugal force, and it is difficult to flow out from the water outlet channel. Moreover, during the rotation process, the liquid can effectively wash away any position in the cleaning tray, avoiding the dead angle of cleaning. After sufficient cleaning, only the rotation speed needs to be reduced, and the water flows naturally from the first water outlet channel 6 and the second water outlet channel 8 . If the second water outlet channel 8 is not provided, some sewage will remain in the cleaning tray after cleaning, which affects the actual cleaning effect. The whole process of the invention does not need to disassemble the cleaning disk, which is very convenient.

The present invention also includes electric cleaning equipment with the cleaning disc, such as sweeping machines, washing machines and the like. Depending on the device, bristles or other cleaning accessories are fixed in the bristle fixing holes 13 . The most common choice is to fix the bristles with iron wires, which is simple in structure, low in cost, and easy to maintain. Also can select the supporting assembly that is fixed with bristle or cleaning cotton, be installed on the inner side that is embedded in outer brush plate, and bristle or cleaning cotton are stretched out from bristle fixing hole 13, carry out cleaning operation.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
