DETAILED DESCRIPTION

[0018] 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.

[0019] Embodiment 1:

[0020] Please refer to Figure 1-4A water-saving flushing device for urban public toilets includes a flushing tank 1, a support column 2 is fixedly installed on the upper surface of the flushing tank 1, an outer frame 3 is fixedly installed on the upper surface of the support column 2, an air inlet 4 is fixedly installed on the front surface of the outer frame 3, a first non-return valve 5 is arranged on the outer surface of the air inlet 4, an air inlet pipe 6 is fixedly installed on the lower surface of the outer frame 3, a second non-return valve 7 is fixedly installed on the outer surface of the air inlet pipe 6, a servo motor 8 is fixedly installed on the upper surface of the outer frame 3, a screw rod 9 is movably installed on the inner wall of the outer frame 3, a push plate 10 is threadedly connected to the outer surface of the screw rod 9, a slide groove 11 is opened on the inner wall of the outer frame 3, and a flow sensor 17 is fixedly installed on the lower surface of the flushing tank 1.

[0021] Specifically: During the use of the new type, when the person finishes flushing it, the flow sensor 17 will detect the water output of the water outlet pipe 15 in real time. When the detected water output is large, the servo motor 8 is started, driving the screw rod 9 to rotate counterclockwise. The screw rod 9 rotates counterclockwise, thereby driving the push plate 10 to move downward. When the push plate 10 moves downward, the gas inside the outer frame 3 is pressed into the inside of the flushing tank 1 through the air inlet pipe 6, thereby pressurizing the water inside the flushing tank 1. The pressurized water flushes the feces again through the water outlet pipe 15, thereby flushing it away. When the flushing is completed, the servo motor 8 drives the screw rod 9 to rotate clockwise, thereby driving the push plate 10 to move upward. The push plate 10 moves upward, thereby sucking the external gas into the inside of the outer frame 3 through the air inlet 4, thereby completing the collection of the gas.

[0022] In this embodiment: a water outlet pipe 15 is fixedly installed on the lower surface of the flush tank 1, and a water inlet pipe 16 is fixedly installed on the rear surface of the flush tank.

[0023] Specifically: the water inlet pipe 16 is externally connected to a water source so as to replenish the water source inside the flushing water tank 1 .

[0024] In this embodiment: the air inlet 4 is interconnected with the interior of the outer frame 3, the first one-way valve 5 controls the air inlet 4 to only allow air to enter, the interior of the flush tank 1 is interconnected with the interior of the outer frame 3 through the air inlet pipe 6, the second one-way valve 7 controls the gas to only enter the interior of the flush tank 1 through the interior of the outer frame 3, the output end of the servo motor 8 is fixedly connected to the upper end of the screw rod 9, and the outer surface of the push plate 10 is movably connected to the inner wall of the slide groove 11.

[0025] Specifically, the slide groove 11 is designed to provide support force for the movement of the push plate 10 to prevent it from rotating along with the screw rod 9.

[0026] In this embodiment, the interiors of the water outlet pipe 15 and the water inlet pipe 16 are interconnected with the interior of the flushing pipe.

[0027] Working principle: The utility model pressurizes the flushing water by pressurizing it, so that the flow rate of the flushing water when it comes out from the outlet pipe 15 is faster, thereby achieving the flushing of larger feces. It is particularly mentioned again that the flushing water continuously enters the inside of the flushing tank 1 to flush the feces. The water inside the flushing tank 1 is always in a state of being half full. Compared with the related art, the utility model provides a water-saving flushing device for urban public toilets with the following beneficial effects: the design can pressurize the water, thereby achieving the effect of flushing larger feces, reducing the flushing time and effectively saving water resources.

[0028] Embodiment 2:

[0029] Please refer to Figure 1-4 A placement frame 12 is fixedly installed on the left inner wall of the flush tank 1, a through hole 13 is provided on the surface of the placement frame 12, and a movable door 14 is hingedly connected to the upper surface of the placement frame 12.

[0030] Specifically: when it is necessary to add a toilet cleaning block to the inside of the flushing tank 1, the movable door 14 is opened, and the toilet cleaning block adapted thereto is placed inside the placement frame 12, and then the movable door 14 is closed. At this time, the water inside the flushing tank 1 will enter the inside of the placement frame 12 through the through hole 13, thereby dissolving the toilet cleaning block in the water, achieving the effect of flushing and cleaning it.

[0031] In this embodiment, the upper surface of the placement frame 12 is interlaced and connected with the upper surface of the flushing tank 1 .

[0032] Specifically: the movable door 14 is displayed on the upper surface of the flush tank 1, so as to facilitate opening and closing.

[0033] Working principle: When the squat pit needs to be cleaned manually, the toilet cleaning block is placed inside the placement frame 12, dissolved in water, and then flushed down through the flush tank 1 to clean the inner wall of the squat pit. The staff uses a toilet brush to assist in cleaning. Compared with the related art, the utility model provides a water-saving flushing device for urban public toilets with the following beneficial effects: the design can realize the design of convenient placement of toilet cleaning blocks, and there is no need to manually prepare flushing liquid for flushing, which saves cleaning time.

[0034] The flushing tank 1 is an existing structure and is common knowledge in the art. It is only used without modification and will not be described in detail.

[0035] The above-mentioned equipment is used in different ways for each device. It is selected and used according to actual conditions, and various parameters are referred to, in accordance with the functions of the equipment used and the effects achieved.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
