OCR 09WP 28/11/2568 1. Hair washing cart, fully assembled. The lower structure (14) serves as the base for the installation of the clean water tank (40), waste water tank (65), automatic water pump (80), and battery (90). The lower structure (14) is attached to the upper structure (12) with a lifting device (13). The clean water tank (40) is a box with a clean water tank lid (41) on top and holds clean water and delivers it to the automatic water pump (80), to which the clean water tank (40) is connected by pipe one (81). The clean water tank (40) has an automatic shut-off valve (62) mounted on its lid (41), which is connected to a quick coupling (87) by pipe five (88), to which the quick coupling (87) serves as a connection for an external clean water hose to fill the clean water tank (40). The waste water tank (65) is a box with a waste water tank lid (66) on top and It serves to hold wastewater received from the hair washing basin (17) and drains the wastewater from the waste tank (65) through the fourth valve (76). The fourth valve (76) accommodates a connection to an external drain hose to drain wastewater from the waste tank (65), where the waste tank (65) is connected to the hair washing basin (17) on the upper structure (12) by a drain pipe (23). One end of the drain pipe (23) is connected to the hair filter (75) mounted on the lid of the waste tank (66). The hair filter (75) filters out hair in the wastewater before it is filled into the waste tank (65). The automatic water pump (80) receives clean water from the clean water tank (40) and performs The function of the clean water pump is to push clean water from the clean water tank (40) to the flexible shower head (16) and nozzle (18) via a second pipe (82) by an automatic water pump (80) powered by battery (90) and automatically starts/stops in sync with the opening and closing of the flexible shower head (16) or nozzle (18). The battery (90) powers the hair washing cart and also supplies power to the user notification mechanism, switch (91), first relay (110), second relay (111), automatic water pump (80), clean water level indicator, and waste water level indicator. The first relay (110) and the second relay (111) control the operation of the automatic water pump (80), and switch (91) is the on/off switch for controlling the operation of the hair washing cart. The upper structure (12) is attached to the lower structure (14) with a lifter (13) and serves as the base for installing the hair washing basin (17), the flexible shower head (16) with nozzles and a holder (19), and the headrest (20) which is angled down at 10 degrees to the horizontal, and the nozzle holder (19) has a slot for receiving the nozzle (18). The lifter (13) is a jack that lifts the upper structure (12) and serves to attach the upper structure (12) to the lower structure (14). The lifter (13) consists of a crossbar (120) with both ends The two sides are joined together by the first cross brace (125), the second cross brace (126), the third cross brace (127), the fourth cross brace (128), the first cross leg (121), the second cross leg (122), the third cross leg (123), and the fourth cross leg (124), which are used to anchor to the upper structure (12) and the lower structure (14). The first cross leg (121) and the second cross leg (122) are fixed to the lower structure (14) and the upper structure (12), and the third cross leg (123) and the fourth cross leg (124) are anchored to the lower structure (14) and the upper structure (12) by sliding pegs. Where the first cross joint (125) and the third cross joint (127) are connected by a third screw (129), one end of which is connected to a handle (37). Specifically, this handle (37) rotates counterclockwise, causing the third screw (129) connected to the handle (37) to push the third cross joint (127) towards the first cross joint (125), raising the upper structure (12). Conversely, this handle (37) rotates clockwise, causing the third screw (129) connected to the handle (37) to push the third cross joint (127) away from the first cross joint (125), lowering the upper structure (12), and the automatic shut-off valve (62) controls the flow of clean water. To the clean water tank (40) from the quick coupling (87), the automatic shut-off valve (62) stops the flow of clean water into the clean water tank (40) when the amount of clean water inside the clean water tank (40) is full or reaches a specified level, and the automatic shut-off valve (62) starts releasing clean water into the clean water tank (40) when an external clean water hose is connected to the quick coupling (87) and the level of clean water inside the clean water tank (40) drops or falls below the specified level. The clean water tank lid (41) has slots to accommodate five vertical clean water level gauges inside the clean water tank (40), namely gauges A (53), B (54), C (55), D (56), and E (57). Gauges A (53), B (54), C (55), and E (57) serve the function of The clean water level in the clean water tank (40) is detected in conjunction with rod D (56) which acts as a ground, and the user is alerted via a user alert method. One end of rods A (53), B (54), C (55), D (56), and E (57) are positioned vertically away from the floor of the clean water tank (40) at intervals of 95% to 90%, 60% to 50%, 30% to 20%, 15% to 10%, and 15% to 10% of the height of the clean water tank (40), respectively. The drain tank lid (66) has four vertically positioned outlets for the drain level rods. Inside the waste water tank (65) are the AA (70), BB (71), CC (72) and DD (73) rods. The AA (70), BB (71), CC (72) and DD (73) rods are used to detect and alert the user to the waste water level inside the waste water tank (65) via a user alert mechanism. One end of the AA (70), BB (71), CC (72) and DD (73) rods are positioned vertically 5% to 10% and 90% to 95% of the height of the waste water tank (65) above the bottom of the waste water tank (65). The user alert mechanism is divided into 7 alert levels based on the level of clean water inside the clean water tank (40) and the level of waste water inside the waste water tank (65), i.e., full tank, half tank. The clean water level is one-quarter of the tank, the clean water level is empty, the waste water level is full, the waste water level is remaining, and the waste water level is empty. The full clean water level is the condition from when the automatic shut-off valve (62) stops the flow of clean water until the clean water level inside the clean water tank (40) drops below the end of rod A (53). The half clean water level is the condition when the clean water level inside the clean water tank (40) drops below the end of rod B (54). The one-quarter clean water level is the condition when the clean water level inside the clean water tank (40) drops below the end of rod C (55). The empty clean water level is the condition when the clean water level inside the clean water tank (40) drops below the ends of rod D (56) and rod E (57), where rod D (56) and rod E (57) are connected. with relay one (110) and sends a signal to relay one (110) to stop the automatic water pump (80) when the clean water inside the clean water tank (40) drops below the ends of the D rod (56) and E rod (57). Full waste water tank is the condition where the waste water inside the waste water tank (65) rises to the ends of the CC rod (72) and DD rod (73), where the CC rod (72) and DD rod (73) are connected to relay two (111) and send a signal to relay two (111) to stop the automatic water pump (80) when the waste water inside the waste water tank (65) drops below the ends of the CC rod (72) and DD rod (73), and the CC rod (72) and DD rod (73) send a signal to relay two (111) to start the automatic water pump (80) when the waste water inside the waste water tank (65) is above the ends of the CC rod (72). and the DDD rod (73), the wastewater level in the tank is the condition in which the wastewater level inside the wastewater tank (65) is higher than the ends of the AA rod (70) and the BB rod (71), and the wastewater level is the condition in which the wastewater level inside the wastewater tank (65) is lower than the ends of the AA rod (70) and the BB rod (71). 2.
