[0086] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0087] like Figures 1-15 As shown, the present invention provides an embodiment of an electric scrubbing vehicle tool.

[0088] The electric scrubbing vehicle tool 1 includes an electric scrubbing head and a handle connected to the electric scrubbing head. A circulating water tank for cleaning and collecting circulating water is provided on the handle. The circulating water tank includes a water tank body 20 with a first cavity X. The water tank body 20 is provided with an inlet / outlet mechanism 10 for allowing water to enter or exit the first cavity X. The water tank body 20 is also provided with a pressure relief mechanism 205 connecting the inside and outside of the first cavity X. The pressure relief mechanism 205 includes a second cavity Y and a third cavity Z that are independently set with respect to the first cavity X. A filter assembly 2059 is provided between the second cavity Y and the first cavity X. An air passage component 2053 is provided between the third cavity Z and the second cavity Y. The third cavity Z is connected to an exhaust nozzle 203 that connects to the outside.

[0089] Specifically, such as Figure 5 , Figure 7 , Figure 9 , Figure 11 As shown, since the exhaust nozzle 203 is connected to the first cavity X, the second cavity Y and the third cavity Z by the pressure relief mechanism 205, liquid can be prevented from entering the exhaust pipe, without affecting air discharge, and the pressure generated in the circulating water tank device 1 when the liquid is recycled during use can be effectively released.

[0090] Specifically, such as Figure 6 , Figure 9 As shown, the water tank body 20 has a groove (not shown in the attached figure), on which a removable and maintainable pressure relief mechanism 205 is sealed and installed. The pressure relief mechanism 205 includes a base plate 2058 that can be removed from the water tank body 20, an air passage component 2053 sleeved on the base plate 2058, a filter assembly 2059 disposed on the base plate 2058, and a removable sealing cover 2051 that is attached to the groove. A sealing ring 2052 that forms a sealing connection with the groove is sleeved on the downwardly extending sealing wall of the pressure relief mechanism cover 2051. Each end of the base plate 2058 has a pressure relief port 2054, and the pressure relief port 2054 extends upward with a flange. The two air passage components 2053 are respectively... The pressure relief port 2054 is not fitted onto the flange. On the back side of the flange of the base plate 2058, a first pressure relief connector 2055 and a second pressure relief connector 2056 with 90-degree bends are respectively provided. The first pressure relief connector 2055 and the second pressure relief connector 2056 are connected by two sections of pressure relief hose 60 and a three-way connector 2057. The three-way connector 2057 itself has no direct connection to the base plate 2058. The two horizontal interfaces of the three-way connector 2057 are connected to the first pressure relief connector 2055 and the second pressure relief connector 2056 respectively through the pressure relief hose 60. One vertical port of the three-way connector 2057 is connected to the exhaust nozzle 203 through the pressure relief hose 60.

[0091] Specifically, such as Figure 6 , Figure 9 As shown, the pressure relief mechanism cover 2051, sealing ring 2052, and base plate 2058 form a second cavity Y contained within the circulating water tank device 1. The filter assembly 2059 and the air passage component 2053 are respectively disposed at both ends of the second cavity Y along one side of the water tank body 20. The air passage component 2053 includes a cylindrical air chamber (not shown in the figure) communicating with the second cavity Y and a flat air nozzle (not shown in the figure) connected to the air chamber at the other end. The two air passage components 2053, the first pressure relief connector 2055, the second pressure relief connector 2056, the three-way connector 2057, the three-section pressure relief hose 60, and the exhaust nozzle 203 form a third cavity Z contained within the circulating water tank device 1.

[0092] like Figure 9 As shown, the two filter components 2059 are the starting points of the path for the first cavity X to release air pressure outward, and the two filter components 2059 are also the starting points of the path for the second cavity Y to receive released air pressure. The two air passage components 2053 are the ending points of the path for the second cavity Y to release air pressure outward, and the two air passage components 2053 are also the starting points of the path for the third cavity Z to receive released air pressure. The exhaust nozzle 203 is the ending point of the path for the third cavity Z to release air pressure to the outside.

[0093] As a further improved implementation, the air passage component 2053 is not limited to the flat-nozzle one-way valve structure described above. Other structures that can function as one-way valves and allow one-way air passage can also be used to replace the air passage component 2053. Simple modifications and substitutions made by those skilled in the art based on the foregoing and following descriptions, without requiring any creative effort, to arrive at technical solutions similar to this application are all within the protection scope of this application.

[0094] Specifically, such as Figure 5 , Figure 7 , Figure 9 , Figure 12 , Figure 13 As shown, the circulating water tank device 1 is equipped with an anti-loosening component that ensures a tight fit between the water tank and the cleaner after installation. The anti-loosening component protrudes above the surface of the water tank body 20, and its lower opening has a funnel shape. In this embodiment, the anti-loosening component is preferably made of an elastic material. During use, because the anti-loosening component protrudes slightly above the water tank body, it fills the gap between the water tank body and the fixed water tank structure, reducing the likelihood of loosening after installation. The anti-loosening component is preferably positioned between the installation ramp and the snap-fit ​​mechanism, and has a large contact surface with the fixed water tank structure.

[0095] Specifically, such asFigure 7 , Figure 12 As shown, the anti-loosening component is a cylindrical cover 2034 disposed at the lower part of the exhaust nozzle 203.

[0096] Specifically, such as Figure 7 , Figure 12 As shown, the vent nozzle 203 includes a fixing sleeve 2033 that is fitted and limited by the ejector pin 2031. The outer wall of the fixing sleeve 2033 is provided with an annular mounting groove (not shown in the figure). A sealing O-ring 2035 is provided in the annular mounting groove. The sealing O-ring 2035 is in sealing contact with the pressure relief mechanism connecting seat 204 fitted on the fixing sleeve 2033. A flower-shaped neck-shaped constriction part (not shown in the figure) is provided at the lower end of the fixing sleeve 2033. The lower end is detachably connected to the cylindrical cover 2034 by clamping the annular protrusion (not shown in the figure) of the cylindrical cover 2034 with the flower-shaped neck-type constriction. The outer wall of the cylindrical cover 2034 smoothly transitions to the outer wall of the lower end of the fixing sleeve 2033. The lower end opening of the cylindrical cover 2034 opens downward in a trumpet shape. A sealing ring 2032 is fitted on the neck (not shown in the figure) of the foremost abutment end face (not shown in the figure) of the ejector pin 2031, slightly upward. Figure 13 As shown, the sealing ring 2032 has extensions on both sides in the vertical direction of its diameter, namely a first extension 20321 and a second extension 20322. A protrusion 20323 is provided outward in the diametrical direction. This protrusion 20323 has a sealing mating surface (not shown in the figure) that seals with the lower end of the fixed sleeve 2033 (a curved neck-shaped opening). This sealing mating surface is beveled. Because the sealing mating surface is beveled, a better sealing effect can be achieved during the sealing process. A clearance (not shown in the figure) is provided between the lower end of the fixed sleeve 2033 (a curved neck-shaped opening) and the sealing ring 2032, providing space for the elastic deformation of the protrusion 20323. This makes it easier to achieve a sealing effect during the sealing process and prevents an overly tight fit that would require significant force to release during discharge. Figure 12 As shown, the neck of the ejector pin 2031 is provided with a groove for accommodating the spring 2036 (not shown in the figure). The other end of the spring 2036 abuts against the abutting protrusion (not shown in the figure) of the pressure relief mechanism connecting seat 204. When the abutting end face of the foremost end of the ejector pin 2031 is pressed by an external force, the ejector pin 2031 further compresses the spring 2036, thereby causing the sealing mating surface on the protrusion 20323 of the sealing ring 2032 to leave the lower end of the fixed sleeve 2033, thus opening the passage of the third cavity Z to the outside.

[0097] As a further improved implementation method, such as Figure 9 , Figure 12As shown, the anti-loosening component can specifically be a cylindrical cover 2034 that is snapped onto the lower end of the fixing sleeve 2033. The lower end opening of the cylindrical cover 2034 is funnel-shaped, and the annular protrusion on the inner wall of the upper end opening of the cylindrical cover 2034 is detachably snapped onto the outer wall of the flower-shaped neck-shaped constriction at the lower end of the fixing sleeve 2033. The cylindrical cover 2034 is disposed on the exhaust nozzle 203.

[0098] Specifically, such as Figure 8 , Figure 9 As shown, the water tank body 20 is provided with a locking mechanism for fixed installation. Specifically, this locking mechanism consists of a recessed locking portion 201 on the water tank body 20, and a further recessed locking groove 202 on the locking portion 201. When fixing the circulating water tank device 1, the corresponding latches on the cleaner can engage with the locking grooves 202 of the locking portion 201. When it is necessary to remove the circulating water tank device 1, the corresponding latches can be released to remove the circulating water tank device 1. An installation slope (not shown in the attached diagram) is provided at the end of the water tank body 20 opposite to the latches.

[0099] As a further improved embodiment, the water tank body 20 is provided with a fixedly installed latching mechanism (not shown in the figure). The latching mechanism has a latch tongue (not shown in the figure) that extends and retracts along the length direction of the water tank body, an elastic component (not shown in the figure) that extends the latch tongue, and a movable operating component (not shown in the figure) that can retract the latch tongue.

[0100] Specifically, such as Figure 5 , Figure 7 , Figure 10 , Figure 11 As shown, the water inlet / outlet mechanism 10 includes a clean water output component 102 and a wastewater inlet component 103. The clean water output component 102 includes a water outlet pin 1021 with a through hole and a water outlet interface connector 101 sleeved on the water outlet pin. A water outlet pressure spring 1025 is sleeved on the water outlet pin to keep the structure in an extended position. The water outlet pin includes an ejector part (not shown in the figure) that cooperates with the clean water outlet (not shown in the figure) on the water outlet interface connector 101 and a water outlet limiting part 1023 that restricts the movement position. A water outlet sealing ring 1022 is provided between the ejector part and the clean water outlet. When the water outlet pin 1021 is pushed and moved, the through hole communicates with the clean water outlet. The water outlet interface connector has a water outlet cavity (not shown in the figure) that communicates with the water tank. This water outlet cavity can form a water outlet channel 1024 with the clean water outlet through the through hole.

[0101] Specifically, such as Figure 5 , Figure 7 , Figure 10 , Figure 11As shown, the sewage inlet assembly 103 includes a return water pin 1031 with a through hole and a return water interface connector 101 sleeved on the return water pin. A return water pressure spring 1035 is sleeved on the return water pin 1031 to keep the outlet pin structure in an extended position. The return water pin 1031 includes an ejector portion (not shown in the figure) that cooperates with the return water inlet (not shown in the figure) on the return water interface connector 101 and a return water limiting portion 1023 that restricts its movement. A return water sealing ring 1032 is provided between the ejector portion and the return water inlet. When the outlet pin is pressed and moved, the through hole communicates with the return water inlet. The return water interface connector has a return water cavity (not shown in the figure) communicating with the water tank. This return water cavity can form a return water channel 1034 with the return water inlet through the through hole.

[0102] Specifically, such as Figure 5 , Figure 7 , Figure 9 , Figure 11 As shown, the outlet interface connector and the return interface connector are an integral structure, which can be collectively referred to as interface connector 101. The return water cavity and the outlet water cavity are set independently. The return water pin 1031 and the outlet water pin 1021 are respectively provided with fixing grooves for fixing the return water sealing ring 1032 and the outlet water sealing ring 1022 (not shown in the figure).

[0103] As a further improved implementation, the outlet interface connector and the return interface connector are detachable and combinable separate structures. The return water cavity and the outlet water cavity are set independently. The outlet interface connector and the return water interface connector are combined together to form a complete interface connector 101. The return water pin 1031 and the outlet water pin 1021 are respectively provided with fixing grooves for fixing the return water sealing ring 1032 and the outlet water sealing ring 1022 (not shown in the figure).

[0104] Specifically, such as Figure 7 , Figure 11As shown, the clean water output component 102 and the wastewater inlet component 103 of the water inlet / outlet mechanism 10 are elastically clamped between the interface end connector 101 and the bottom shell 104 of the water inlet / outlet mechanism. One end of the outlet pressure spring 1025 abuts against the outlet pin 1021 and the other end abuts against the bottom shell 104 of the water inlet / outlet mechanism. One end of the return pressure spring 1035 abuts against the return pin 1031 and the other end abuts against the bottom shell 104 of the water inlet / outlet mechanism. The interface end connector 101 has openings at both ends. The end with the larger opening has an outwardly expanding snap-fit ​​interface edge with a certain strength and thickness (not shown in the figure). The end with the smaller opening is sleeved on the water inlet / outlet... On the inner wall of the water mechanism base shell 104, the interface end connector 101 is provided with a partition (not shown in the figure) on the side near the large opening end to block the opening. The partition is provided with a conical through hole that abuts against the water outlet pin 1021 and the water return pin 1031. A sealing gasket 105 is sandwiched between the small opening end face of the interface end connector 101 and the inner bottom wall of the water inlet and outlet mechanism base shell 104. The sealing gasket 105 is made of elastic material. After the interface end connector 101 and the water inlet and outlet mechanism base shell 104 are detachably connected by fastening screws, the elastic sealing gasket 105 can fill the gap between the two to effectively prevent leakage. The outer walls of the large and small ends of the interface connector 101 maintain two different outer diameters. The outer wall of the interface connector 101 must be provided with a step (not shown in the figure) that divides the large and small ends. The lower part of the snap-fit ​​edge of the large end of the interface connector 101 extends to the outer wall of the step and is fitted with a sealing ring 1011. The sealing ring 1011 can seal the gap between the water inlet / outlet mechanism 10 and the water tank body 20 after they are snapped together. The bottom shell 104 of the water inlet / outlet mechanism is open at one end, and the interface end connector 101 is sleeved on the open end. The other end is closed, but a through hole is provided on the closed end face to communicate with the clean water output component 102 and the sewage inlet component 103. A water suction pipe interface 1043 is provided on the closed end face of the bottom shell 104 of the water inlet / outlet mechanism, extending outward from the through hole of the clean water output component 102. Around the water suction pipe interface 1043, a filter component connection port 1042 extends outward from the closed end face of the bottom shell 104 of the water inlet / outlet mechanism. The inner wall of the filter component connection port 1042 is provided with threads (not shown in the figure). The inner thread is coupled and detachably connected to the outer thread (not shown in the figure) of the filter component connection port 401 at the open end of a cylindrical filter component 40. The peripheral wall and bottom wall of the filter component 40 are provided with multiple hollow structures (not shown in the figure), and its outer surface is covered with a filter screen (not shown in the figure).A suction pipe 106 is fitted onto the suction pipe interface 1043. The suction pipe 106 extends to the area close to the bottom wall of the filter assembly 40. This allows the water filtered in the filter assembly 40 within the circulating water tank device 1 to still be drawn in by the suction pipe 106 when the water inlet / outlet mechanism 10 is facing upwards. This drawable state is maintained until the water level of the filtered water in the filter assembly 40 is lower than the lowest opening of the suction pipe 106 (not shown in the figure). In addition to the filter assembly connection port 1042, a sewage return port 1045 communicating with the sewage inlet assembly 103 is provided on the closed end face of the bottom shell 104 of the water inlet and outlet mechanism. The sewage after cleaning by the cleaner enters the first cavity X in the circulating water tank device 1 through the return water channel 1034 and then through the sewage return port 1045. After being filtered by the filter assembly 40, the sewage is sucked into the outlet channel 1024 through the suction pipe 106 and finally sent out to the water outlet passage (not shown in the figure) of the cleaner through the clean water output assembly 102. A vent hole 1041 is provided inside the filter assembly connection port 1042 on the closed end face of the bottom shell 104 of the water inlet and outlet mechanism. When the water inlet and outlet mechanism 10 is facing upward and the pressure relief mechanism 205 loses its pressure regulating function, the circulating water tank device 1 still has a pressure relief channel to slightly adjust the gas pressure inside and outside the circulating water tank device. When the water inlet and outlet mechanism 10 is facing downward and the water level in the filter assembly 40 is lower than the highest opening of the water suction pipe 106, water can still enter the water outlet channel through the vent hole 1041 and then be sent out to the water outlet passage of the cleaner (not shown in the figure) through the clean water output component 102. A guide rib 1046 is provided on the outer wall of the bottom shell 104 of the water inlet / outlet mechanism that mates with the water tank body 20. The guide rib 1046 helps the installed water inlet / outlet mechanism 10 to be easily inserted into the water tank body 20. Since the outer wall of the water inlet / outlet mechanism 10 that mates with the water tank body 20 has a regular symmetrical shape, the guide rib 1046 can also play a role in preventing reverse connection.

[0105] Specifically, such as Figure 5 , Figure 6 , Figure 7As shown, the circulating water tank device 1 includes an upper body 206 and a lower body 207. The upper body 206 and the lower body 207 are connected by a sealed connection. The bottom of the lower body 207 extends upwards on a sloped side. The top of the slope, opposite to the water inlet / outlet mechanism 10, has a concave snap-fit ​​part 201 for easy installation and fixing. This snap-fit ​​part has a concave snap-fit ​​groove 202. When fixing the circulating water tank device 1, the corresponding buckle on the cleaner can be engaged in the snap-fit ​​groove 202 of the snap-fit ​​part 201. When it is necessary to remove the circulating water tank device 1, the corresponding buckle can be released to remove the circulating water tank device 1.

[0106] As a further improved implementation, the upper body 206 and the lower body 207 of the water tank are sealed together by an ultrasonic welding layer (not shown in the figure).

[0107] As a further improved implementation, the upper body 206 and the lower body 207 of the water tank are sealed together by a secondary injection molding process.

[0108] As a further improved implementation, the upper body 206 and the lower body 207 of the water tank are sealed together by a direct bonding process.

[0109] Specifically, such as Figure 14 As shown, when the inlet / outlet mechanism 10 of the circulating water tank device 1 is tilted downwards, a portion of the pressure relief mechanism 205 on the side away from the inlet / outlet mechanism 10 is above the liquid surface H. Regardless of whether the opening of the suction pipe 106 is always below the liquid surface H, the circulating water tank device 1 still has the ability to release pressure to the outside of the circulating water tank device and also has the ability to continuously output clean water. When the inlet of the suction pipe 106 is below the liquid surface H, the suction pipe 106 can naturally achieve the function of "discharging water". When the inlet of the suction pipe 106 is above the liquid surface H, the vent 1041 of the inlet / outlet mechanism 10 is lower than the liquid surface H and is only a very small bypass branch of the outlet channel 1024. The bypass branch of the vent 1041 can achieve the function of "discharging water" under the pressure of the liquid surface H. At the same time, due to the pressure difference between the inside and outside of the circulating water tank device 1, the circulating water tank device of the cleaner used in this manner has the ability to supply water to the outside and release pressure to the outside.

[0110] Specifically, such as Figure 15As shown, when the inlet / outlet mechanism 10 of the circulating water tank device 1 is tilted upwards, a portion of the pressure relief mechanism 205 is located above the liquid surface H on the side close to the inlet / outlet mechanism 10. At this time, the opening of the suction pipe 106 is lower than the liquid surface H. Under the combined action of water pressure and air pressure, the pressure is directly applied to the vent 203 of the circulating water tank device 1 through the pressure relief mechanism 205 and along the pressure relief pipeline. The vent 203 can be specifically a one-way valve. Due to the one-way conduction function of the one-way valve, the one-way valve is compacted and closed under the combined action of water pressure and air pressure. The vent 1041 of the water inlet / outlet mechanism 10 is higher than the liquid level H and is only a very small bypass branch of the water outlet channel 1024. The vent 1041 is open to the outside atmosphere. A circuitous structure (not shown in the attached diagram) is provided before the vent 1041 to block water flow to the bypass branch. Simply put, the bypass branch of the vent 1041, which is open to the outside atmosphere, can achieve the effect of "breathable but not water-permeable". At this time, the bypass branch of the vent 1041, which is open to the outside atmosphere, has the ability to release pressure outside the water supply device. Simultaneously, due to the pressure difference inside and outside the water supply device, and because the suction pipe 106 always has an inlet and / or suction hole below the liquid level H, the clean water output component can continuously output clean water. The water supply device of the car wash device used in this configuration has the ability to release pressure outside the water supply device and continuously output clean water. Of course, when the liquid level H is lower than the water inlet of the suction pipe 106, the circulating water tank device 1 will also be unable to continuously output clean water. At this time, the user is reminded to add clean water to the circulating water tank device 1 so that the cleaner can continue to be used.

[0111] like Figure 16 As shown, the present invention provides another embodiment of an electric scrubbing vehicle tool.

[0112] Unlike the previous embodiment, the second pressure relief connector 2056 is replaced with a T-connector, eliminating the original T-connector 2057. The horizontal ends of the first pressure relief connector 2055 and the second pressure relief connector 2056 are directly connected by the pressure relief hose 60, and the other vertical end of the second pressure relief connector 2056 is connected to the vent 203 by the pressure relief hose 60. The vent 203 is located near the rear of the circulating water tank device 1. This design allows the filter assembly 40 to have more space to install a filter screen and increase the filtration effect without increasing its diameter. At the same time, it allows the water suction pipe 106 to extend further, reducing the possibility of unusable residue remaining in the circulating water tank device 1 when the inlet / outlet mechanism 10 is tilted upwards.

[0113] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
