DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0026] The utility model discloses a kind of scrubber devices of scrubber, belong to the accessory of scrubber, install in the bottom of scrubber, with rotary brush and water outlet in front of squeegee, by the brush of rotary brush and water, form sewage, squeegee is used to gather and adsorb sewage to sewage tank.

[0027] As Figure 1 The utility model discloses a kind of scrubber devices of scrubber, belong to the accessory of scrubber, install in the bottom of scrubber, with rotary brush and water outlet in front of squeegee, by the brush of rotary brush and water, form sewage, squeegee is used to gather and adsorb sewage to sewage tank.

[0028] First squeegee installation slot 3 is located in scrubber front side, and second squeegee installation slot 4 is located in scrubber rear side.

[0029] First squeegee installation slot 3 and second squeegee installation slot 4 are respectively inserted with squeegee 5, in the utility model, squeegee 5 is consumable component, needs to be replaced periodically, squeegee 5 in the utility model does not need other installation and dismounting tool, can be directly installed and dismounted by hand.

[0030] As Figure 2 The edge of squeegee 5 in first squeegee installation slot 3 and ground is equipped with continuous water inlet 6, to facilitate when advancing, sewage enters between two squeegees 5 from water inlet 6, relatively forms concentrated area, to facilitate forming concentrated negative pressure area at suction port 2, improve adsorption efficiency.

[0031] Further, first squeegee installation slot 3 and second squeegee installation slot 4 are both arc structure, and the concave surface of its arc structure is towards advancing direction when scrubber works, can effectively gather sewage, increase the water level of sewage, increase its gravitational potential energy, accelerate its through water inlet 6 and enter the area between first squeegee installation slot 3 and second squeegee installation slot 4.

[0032] Further, the arc of first squeegee installation slot 3 is greater than the arc of second squeegee installation slot 4, reduces both sides passageway, improves the water storage capacity of the area between first squeegee installation slot 3 and second squeegee installation slot 4, creates more time for suction port 2 to adsorb sewage, also retains certain gap in both sides passageway, lets internal air leak from gap, avoids the phenomenon that suction port 2 adsorption force is less than the water inlet air inlet rate of the area between first squeegee installation slot 3 and second squeegee installation slot 4, causes the pressure of the area between first squeegee installation slot 3 and second squeegee installation slot 4 and external pressure close, prevents sewage from entering water inlet 6.

[0033] Further, when the suction port 2 has a large enough suction force, the same side end of the first scraping strip mounting groove 3 and the second scraping strip mounting groove 4 can be connected, that is, both sides are closed, so that the first scraping strip mounting groove 3 and the second scraping strip mounting groove 4 form a relatively closed crescent groove structure 9, and the suction port 2 is located at the middle position of the crescent groove structure 9. In the strong suction state, it is difficult to store sewage in the crescent groove structure 9, that is, a negative pressure is formed in the crescent groove structure 9, thereby increasing the water suction capacity at the water inlet 6. In this working condition, a larger size of the water inlet 6 is preferably used.

[0034] In order to further improve the suction efficiency of the suction port 2, a funnel structure 8 is formed at the middle position of the suction port 2 and the crescent groove structure 9. The funnel structure 8 is a modified channel structure, so that the path of the sewage entering the suction port 2 is smoother, and the inlet channel area of the suction port 2 is increased.

[0035] In the utility model, as shown in the drawings, Figure 3 The inner wall of the slot structure of the first scraping strip mounting groove 3 and the second scraping strip mounting groove 4 is provided with a convex rib 7. The convex rib 7 is perpendicular to the arrangement direction of the floor cleaning machine base. When the scraping strip 5 is installed, the friction in the horizontal direction can be increased, the sliding of the scraping strip 5 in the horizontal direction is avoided, and the scraping strip 5 is prevented from falling out.

[0036] The convex ribs 7 on the front and rear groove surfaces of the slot structure are staggered, further increasing the holding force and clamping stability of the scraping strip 5.

[0037] Further, the slot gap of the first scraping strip mounting groove 3 and the second scraping strip mounting groove 4 gradually increases from the middle to the two ends, facilitating the pressing of the scraping strip 5 into the first scraping strip mounting groove 3 or the second scraping strip mounting groove 4 from the two sides, and improving the operability of manual installation.

[0038] In the utility model, the plurality of water inlets 6 of the scraping strip 5 in the first scraping strip mounting groove 3 are arranged at equal intervals. The arrangement density of the water inlets 6 in the middle region of the scraping strip 5 can also be increased, thereby improving the suction efficiency after the sewage is gathered to the middle position of the arc-shaped structure scraping strip.

[0039] The water inlet 6 is preferably a semicircular structure.

[0040] Further, the radius length of the semicircular structure of the water inlet 6 is 1 / 2-1 / 4 of the height of the part of the scraping strip 5 outside the first scraping strip mounting groove 3. According to the suction force of the suction port 2, a smaller semicircular structure size is required for a small suction force, which can increase the suction force in the area and improve the suction effect. Similarly, the impurities in the sewage are also determined. For example, if the clean area contains more solid particles, a larger semicircular structure size is used to avoid blockage.

[0041] The interval between two adjacent water inlets 6 is 1 / 10-1 / 16 of the length of the first or second blade mounting groove 3 or 4, and the number of water inlets 6 on the blade 5 is determined according to the output of the cleaning liquid of the scrubber, i.e., the amount of formed sewage, and more water inlets 6 are selected when the amount of sewage is larger.

[0042] As shown in Figure 4 The utility model discloses a kind of scrubber squeegee devices, further including with the installation of its matching squeegee storage slot 10, squeegee storage slot 10 is installed on the chassis of scrubber, for with the installation positioning of scrubber squeegee, can provide the detachable function of scrubber squeegee;

[0043] Squeegee storage slot 10 has aperture 11 corresponding with air suction port 2;Squeegee storage slot 10 includes rear baffle 12 combined with second blade mounting groove 4, and front baffle 13 combined with first blade mounting groove 3, scrubber squeegee is limited between front baffle 13 and rear baffle 12, with stronger fixing effect after installation;

[0044] Further, squeegee storage slot 10 has magnetic attraction part 14, the surface of squeegee body 1 has magnet part corresponding with magnetic attraction part 14, after being installed into squeegee storage slot 10, scrubber squeegee can be quickly adsorbed and fixed to suitable position, also improve the stability of scrubber squeegee in use process, not easy to fall off.

[0045] As shown in Figure 5 Squeegee body 1 is provided with guide wheel angle seat 15 at both ends respectively, guide wheel 16 is installed on guide wheel angle seat 15, to facilitate the use of entire scrubber;Guide wheel 16 is auxiliary wheel of scrubber, cooperates with traveling wheel of scrubber, and jointly bears the weight of scrubber, improves the installation stability of squeegee body 1 in squeegee storage slot 10 under the condition that guide wheel 16 bears weight.

[0046] As shown in Figure 5 Suction pipe 17 is inserted into drain pipe 18, and the gap between the two is sealed, drain pipe 18 is connected with sewage pipe of scrubber, and sewage pipe is communicated with sewage tank, under the action of air pump, the sewage tank forms negative pressure adsorption sewage.
