Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of window-cleaning robots, and particularly relates to a water spraying structure of the window-cleaning robot. Background Art
[0002] The window cleaning robot is a type of smart household appliance. It can firmly adhere to the glass with the help of the vacuum pump or fan device at the bottom of itself, and use the force of its own adsorption on the glass to drive the rag at the bottom of the body to wipe off the dirt on the glass, which largely solves the problem of high-rise window cleaning and outdoor window cleaning.
[0003] The window cleaning robots currently on the market usually include a body, two rag discs, and one or two nozzles. The two rag discs are symmetrically arranged at the bottom of the body, and the nozzle is located between the two rag discs. The nozzle is arranged on one side of the body or on both sides of the body. During the cleaning process, the nozzle sprays glass water outward. Since only one nozzle is arranged on a single side of the body, the water spraying volume of the nozzle is small, and the water spraying position of the nozzle is concentrated in the middle of the two rag discs. The water spraying area is small, which can easily cause uneven water distribution on the two rag discs. Water stains are also likely to remain on the glass during the wiping process, affecting the scrubbing efficiency and scrubbing effect of the glass. Utility Model Content
[0004] The purpose of the utility model is to provide a water spraying structure for a window cleaning robot to solve the problems in the prior art of small water spraying amount and small water spraying area of the nozzle, which lead to low cleaning efficiency and poor cleaning effect of the window cleaning robot.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0006] A water spraying structure of a window cleaning robot comprises a body, wherein a first rag disk and a second rag disk are respectively provided on the left and right sides of the bottom of the body;
[0007] A nozzle assembly is provided on the front and rear surfaces of the fuselage. The nozzle assembly is located between the first rag tray and the second rag tray. The nozzle assembly includes a first nozzle and a second nozzle arranged obliquely toward the bottom of the fuselage. The first nozzle and the second nozzle spray glass water toward the left and right sides of the fuselage, respectively. The spray paths of the first nozzle and the second nozzle cover the first rag tray and the second rag tray, respectively.
[0008] The water supply assembly is arranged inside the fuselage, and the water supply assembly includes a water supply tank for storing glass water. The water outlet of the water supply tank is connected to the first water tank and the second water tank. The first water tank and the second water tank are used to transport glass water to the two nozzle assemblies respectively. A pressure stabilizing device is provided in the water supply tank, and the pressure stabilizing device is used to adjust the water pressure in the first water tank and the second water tank.
[0009] Furthermore, the first nozzle and the second nozzle are both ultrasonic atomizing nozzles, the spray shapes of the first nozzle and the second nozzle are conical, and the spray angles of the first nozzle and the second nozzle are 20-30 degrees.
[0010] Furthermore, the two nozzle assemblies each include a mounting block, which is provided with two mounting surfaces inclined toward the bottom of the fuselage, and the first nozzle and the second nozzle are respectively mounted on the two mounting surfaces, and the angle between the first nozzle and the second nozzle is 60°-80°.
[0011] Furthermore, the included angles between the jet axes of the first nozzle and the second nozzle and the front end face or the rear end face of the fuselage are both 40°-60°.
[0012] Furthermore, a water pressure sensor is provided at the water outlet of the water supply tank.
[0013] Furthermore, the body includes a detachably connected shell and cover, a water supply tank is installed inside the shell, a water inlet for adding glass water is provided on the water supply tank, and a switch for opening or closing the nozzle assembly is provided on the cover.
[0014] Furthermore, the mounting block of the nozzle assembly is detachably connected to the fuselage, and the first nozzle and the second nozzle are detachably connected to the mounting block.
[0015] Compared with the prior art, the present invention has the following beneficial technical effects:
[0016] 1. The present invention provides two nozzle assemblies on the body, and each nozzle assembly is equipped with two ultrasonic atomizing nozzles. Compared with the existing single-side single nozzle or double-side single nozzle water spraying structure, it can effectively increase the nozzle's water spraying volume and water spraying area. By setting the installation angle of the first nozzle and the second nozzle to be inclined toward the outside and bottom of the body, the spray paths of the first nozzle and the second nozzle can cover the first and second rag discs, fully soaking the first and second rag discs, thereby improving the scrubbing efficiency and scrubbing effect of the window cleaning robot.
[0017] 2. The utility model sets a water supply assembly. During the water spraying operation of the nozzle assembly, when the water in the water supply tank is sufficient, the water pressure of the glass water itself can meet the normal water spraying operation of the two nozzle assemblies, and the pressure stabilizing device is in a closed state at this time; when the water level in the water supply tank gradually drops, the water pressure of the glass water itself drops accordingly. When the water pressure sensor detects that the water pressure at the water outlet of the water supply tank is difficult to meet the normal operation of the nozzle assembly, the pressure stabilizing device starts, and the glass water in the water supply tank is pressurized and transported to the first water tank and the second water tank, ensuring the normal operation of the nozzle assembly and further improving the scrubbing efficiency and scrubbing effect of the window cleaning robot.

DETAILED DESCRIPTION
[0025] The following is further described in detail through specific implementation methods:
[0026] Example
[0027] like Figure 1-2 As shown, a water spraying structure of a window cleaning robot includes a body, a nozzle assembly 5 and a water supply assembly.
[0028] like Figure 1-2 As shown, the body includes a shell 1 and a cover 2 that are detachably connected. A first rag tray 3 and a second rag tray 4 are respectively provided on the left and right sides of the bottom of the shell 1. A switch 21 for opening or closing the nozzle assembly 5 is provided on the cover 2.
[0029] like Figure 2 As shown, the front and rear surfaces of the fuselage are both provided with nozzle assemblies 5, and the nozzle assembly 5 is located between the first rag plate 3 and the second rag plate 4; Figure 6 As shown, the nozzle assembly 5 includes a mounting block 51 that is detachably connected to the fuselage. Two mounting surfaces 511 are formed on the mounting block 51. The two mounting surfaces 511 face the left and right outer sides of the fuselage, respectively, and the mounting surfaces 511 are inclined toward the bottom of the fuselage. Figure 3-4As shown, the first nozzle 52 and the second nozzle 53 are respectively installed on the two mounting surfaces 511. The first nozzle 52 and the second nozzle 53 are both ultrasonic atomizing nozzles. The first nozzle 52 and the second nozzle 53 spray glass water to the left and right sides of the fuselage respectively. The spray paths of the first nozzle 52 and the second nozzle 53 cover the first rag plate 3 and the second rag plate 4 respectively. Figure 5 As shown, the spray shape of the first nozzle 52 and the second nozzle 53 is conical, the spray angle A of the first nozzle 52 and the second nozzle 53 is 20-30°, and the spray angle A of this embodiment is 25°. The included angle B between the jet axis 54 of the first nozzle 52 and the second nozzle 53 and the front end face or the rear end face of the fuselage is 40-60°, and the included angle B of this embodiment is 50°; the included angle between the first nozzle 52 and the second nozzle 53 is 60°-80°, as shown in FIG. Figure 6 As shown, the included angle C between the first nozzle 52 and the second nozzle 53 of this embodiment is 70°.
[0030] By arranging four ultrasonic atomizing nozzles on the front and rear sides of the fuselage, the water spraying volume and spraying area of the nozzles can be effectively increased, and the installation angles of the first nozzle 52 and the second nozzle 53 are set to be inclined toward the outside and bottom of the fuselage, so that the spray paths of the first nozzle 52 and the second nozzle 53 can cover the first rag plate 3 and the second rag plate 4, fully soaking the first rag plate 3 and the second rag plate 4, thereby improving the scrubbing efficiency and scrubbing effect of the window cleaning robot.
[0031] like Figure 3 As shown, the water supply assembly is arranged inside the shell 1, and the water supply assembly includes a water supply tank 6 for storing glass water. The water supply tank 6 is provided with a water inlet 61 for adding glass water. The water outlet of the water supply tank 6 is connected to the first water tank and the second water tank. The first water tank and the second water tank are respectively used to transport glass water to the two nozzle assemblies 5. The first water tank and the second water tank of this embodiment are arranged inside the mounting blocks 51 of the two nozzle assemblies 5; a pressure stabilizing device is provided in the water supply tank 6, and the pressure stabilizing device is used to adjust the water pressure in the first water tank and the second water tank. The pressure stabilizing device of this embodiment adopts a water pump, and the water outlet of the water supply tank 6 is provided with a water pressure sensor capable of monitoring the water pressure.
[0032] During the water spraying operation of the nozzle assembly 5, when the water volume in the water supply tank 6 is sufficient, the glass water enters the first water tank and the second water tank respectively under the action of its own water pressure to meet the normal water spraying operation of the two nozzle assemblies 5. At this time, the pressure stabilizing device is in a closed state; when the water level in the water supply tank 6 gradually drops, the water pressure of the glass water itself gradually drops. When the water pressure sensor detects that the water pressure at the outlet of the water supply tank 6 is difficult to meet the normal operation of the nozzle assembly 5, the pressure stabilizing device is started, and the glass water in the water supply tank 6 is pressurized and transported to the first water tank and the second water tank, so that the water pressure in the first water tank and the second water tank can always be kept stable to ensure the normal operation of the nozzle assembly 5 and further improve the scrubbing efficiency and scrubbing effect of the window cleaning robot.
