[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0042] like Figure 1-10 As shown, a pressurized water-discharging floor scrubber comprises a machine body 1, a cleaning body 2 arranged at the bottom of the machine body 1, and a clean water tank 3 arranged on the machine body 1, a mounting cavity 4 open upward is arranged at the front side of the cleaning body 2, and a water outlet assembly and a roller brush assembly 5 are detachably arranged in the mounting cavity 4;

[0043] The water outlet assembly includes a waterway plate 6, and a water pump 7 connected to the waterway plate 6 and the clean water tank 3. A step portion 4.1 matching the contour of the waterway plate 6 is provided in the installation cavity 4. A water supply connector 8 connected to the water pump 7 is provided on the step portion 4.1. The waterway plate 6 is plugged with the water supply connector 8. A plurality of water outlets 9 arranged laterally at intervals are provided on the waterway plate 6.

[0044] A waterway channel is provided in the waterway plate 6, and the waterway channel has a water inlet section 6.1 deviated from the center of the water outlet 9, and a booster section 6.2 and a water outlet section 6.3 connected to the water inlet section 6.1, the booster section 6.2 extends outside the water outlet 9 along the waterway direction, and the water outlet section 6.3 detours from the outside to the water outlet 9, and the booster section 6.2 and the water outlet section 6.3 are arranged opposite to each other in the vertical direction, and the projections of the booster section 6.2 and the water outlet section 6.3 in the vertical direction at least partially overlap.

[0045] Among them, the top of the body 1 is provided with an installation position for placing the clean water tank 3, and the clean water tank 3 is detachably arranged on the installation position. By increasing the relative height of the clean water tank 3, it is ensured that the water flow therein has a tendency to flow into the water pump 7, reducing the load of the water pump 7, which is conducive to improving the continuity of water output.

[0046] As a further embodiment of the clean water tank 3, a water outlet valve cover 3.1 is provided on the inner side of the installation position and is connected to the clean water tank 3 by a water path. A first water outlet end pipe 3.2 is provided on the water outlet valve cover 3.1. The inlet of the water pump 7 is connected to the first water outlet end pipe 3.2 by a hose. A second water outlet end pipe 8.1 is provided on the water supply connector 8. The outlet of the water pump 7 is connected to the second water outlet end pipe 8.1.

[0047] As a further implementation method of the water channel, the water inlet section 6.1 is connected to the water supply connector 8, and the water outlets 9 are arranged at equal intervals along the length direction on the waterway plate 6. In this way, the flow rate entering the water channel is guaranteed, and combined with the high-positioned clean water tank 3, the continuity of the water flow in the water channel is further ensured.

[0048] Specifically, the water channel also includes a transition section 6.4, the boosting section 6.2 and the water outlet section 6.3 are extended in the horizontal direction, the transition section 6.4 is vertically arranged and connects the boosting section 6.2 and the water outlet section 6.3, the boosting section 6.2 extends in the horizontal direction and passes through the water outlet 9 in the waterway direction, and then is connected to the water outlet section 6.3 through the vertical transition section 6.4, thereby increasing the water flow path of the water channel, and with the continuous water supply of the water pump 7, the flow rate and water outlet pressure of the water channel are effectively increased.

[0049] In other embodiments, in order to further increase the water flow resistance in the water channel, the caliber of the transition section 6.4 is smaller than that of the boosting section 6.2, and the two adjacent water outlets 9 are interconnected and define a water diversion section 6.5. The water diversion section 6.5 is horizontally arranged, and the water diversion section 6.5 is vertically located between the water outlet section 6.3 and the boosting section 6.2. In this way, while further improving the water path, the water outlet section 6.3 and the water diversion section 6.5 are connected by a vertical transition section 6.4, and on the other hand, the turning position of the water channel is increased to increase the flow rate and pressure of the water when entering the water diversion section 6.5.

[0050] like Figure 5 and Figure 6 As shown, as a further embodiment of the waterway plate 6, the waterway plate 6 includes a water outlet plate 11 and a water sealing plate 10, the water outlet 9 is arranged on the water outlet plate 11, the water outlet plate 11 is provided with a first baffle wall 11.1 for forming a waterway channel, and a second baffle wall 11.2 protruding from the first baffle wall 11.1, and the first baffle wall 11.1 and the second baffle wall 11.2 have the same profile;

[0051] The water sealing plate 10 is connected to the water supply connector 8, and a groove 10.1 matching the contour of the second retaining wall 11.2 is provided on the water sealing plate 10, and a convex portion 10.2 abutting against the second retaining wall 11.2 is provided in the groove 10.1. Through the above improvements, the matching stability and tightness between the water sealing plate 10 and the water outlet plate 11 are guaranteed to avoid water leakage in the water channel.

[0052] The convex part 10.2 can be made of a flexible material to further ensure the water tightness of the water channel, so that the water flow fills the water channel during the water discharge process. Figure 4 , Figure 8 and Fig. 9 In the figure, the convex portion 10.2 and the second retaining wall 11.2 are shown in an overlapping state.

[0053] like Fig. 9 As shown, the first baffle wall 11.1 and the second baffle wall 11.2 are also arranged around the water outlet 9, and the groove 10.1 defines a water sealing portion 10.3 matching the water outlet 9 on the water distribution plate, wherein the water sealing portion 10.3 has a conical protrusion 10.5 extending toward the water outlet 9. In this way, the conical protrusion 10.5 compresses the water outlet space at the water outlet 9 to increase the water outlet pressure and water outlet flow rate at the water outlet 9, and at the same time, the conical protrusion 10.5 guides the outlet water flow.

[0054] Reference Fig. 9 As shown, specifically, the water sealing plate 10 also protrudes with a boosting protrusion 10.4 that matches the contour of the water channel, and the boosting protrusion 10.4 is placed in the water channel and is spaced between the water outlet 9 and the end surface of the water outlet plate 11. Through the above improvement, the boosting protrusion 10.4 compresses the caliber of the water channel, so that there is no need to over-compress the distance between the first baffle walls 11.1, thereby reducing the difficulty of demoulding adjacent first baffle walls 11.1 on the water outlet plate 11.

[0055] Furthermore, the boosting protrusion 10.4 is arranged in a V-shape, and the small end of the boosting protrusion 10.4 extends between the first baffle walls 11.1.

[0056] Reference Figure 8As shown, as a further improvement to the transition section 6.4, in order to increase the pressurization and flow stability of the water flow in the water channel, a baffle assembly is also provided in the transition section 6.4, and the baffle assembly includes a first baffle 13 provided on the water outlet plate 11, and a second baffle 14 provided on the water sealing plate 10, the first baffle 13 extends toward the water sealing plate 10 and is separated from the surface of the water sealing plate 10 by a water gap 15; the second baffle 14 extends toward the water outlet plate 11 and is separated from the water outlet plate 11 by a water gap 15, so that two staggered water retaining parts are formed in the vertical transition section 6.4, so as to play a certain role in accelerating and pressurizing the water flow in the transition section 6.4.

[0057] Optionally, in order to avoid collision noise caused by water flow between the first partition 13 and the second partition 14, water holes 16 are provided on the first partition 13 and the second partition 14, and the water holes 16 are arranged at intervals. The water holes 16 on the first partition 13 are arranged toward the second partition 14, and the water holes 16 on the second partition 14 are arranged toward the first partition 13, so as to ensure the effect of increasing the pressure and speed of the water flow while reducing noise.

[0058] like Figure 7 As shown, in other embodiments, the water outlet side of the water outlet plate 11 is further modified to optimize the water outlet effect. A water outlet column 11.3 corresponding to the water outlet 9 is provided on the side of the water outlet plate 11 away from the water sealing plate 10. Water outlets 11.4 connected to the water outlet 9 are provided on both sides of the axis of the water outlet column 11.3 corresponding to the water outlet 9. A baffle 11.6 extending inward is provided on the water outlet column 11.3. A gap connecting the water outlet 11.4 is formed between the baffle 11.6 and the water outlet 9. Through the above improvements, the water flow is further pressurized in the flow path from the water outlet 9 to the water outlet 11.4, and the water outlet 11.4 expands toward the water outlet direction on the outside of the water outlet 9.

[0059] Specifically, the water spray port 11.4 is arranged in a ring shape on the surface of the water outlet column 11.3, so that the water flow can be diffused toward both sides, and the diameter of the water spray port 11.4 is smaller than the water outlet 9, which has a pressurizing effect on the outlet water flow.

[0060] Specifically, the water outlet plate 11 is provided with water guide surfaces 11.5 with an expansion trend on both sides corresponding to the water outlet columns 11.3, the water guide surfaces 11.5 between adjacent water outlet columns 11.3 are connected, and the water spray ports 11.4 are arranged facing the water guide surfaces 11.5, and the water spray ports 11.4 are arranged obliquely, thereby increasing the water spraying area and improving the cleaning effect on the roller brush surface.

[0061] from Figure 4It can be seen that in other embodiments, a scraper strip 12 is abutted between the waterway plate 6 and the step portion 4.1, a positioning protrusion 4.2 is provided on the step portion 4.1, and a positioning recess 12.1 matching the positioning protrusion 4.2 is provided on the scraper strip 12, and the scraper strip 12 extends out from the step portion 4.1 and abuts against the surface of the roller brush assembly 5. The positioning protrusion 4.2 and the positioning recess 12.1, as well as the crimping effect between the waterway plate 6 and the step portion 4.1, improve the position tightness of the scraper strip 12, and the bottom of the water outlet plate 11 has a downwardly extending oblique stop 11.7, which abuts against the protruding portion of the scraper strip 12 and forces the scraper strip 12 to bend toward the lower side and the front side. In this way, it helps to ensure the structural reliability of the protruding portion 12.2 of the scraper strip 12, reduce the deformation of the scraper strip 12, and ensure that the dirt on the roller brush assembly 5 is scraped off.

[0062] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
