Description
Technical Field
[0001] The utility model relates to a water source pipeline for flushing a toilet in a public toilet, in particular to an auxiliary agent adding device for the flushing pipeline in a public toilet. Background Art
[0002] Common sources of odor in existing public toilet areas, especially in urinal areas, are: 1. Odor emission from feces and urine splashing outside the toilet when using the toilet; 2. Odor return from the toilet sewer pipes; 3. Odor emission from feces and urine adhering to and remaining on the inner surface of the toilet; 4. Odor emission from the feces and urine themselves during excretion when using the toilet. In public toilet areas with dense traffic, the above problems 1-2 and 4 have been improved accordingly through facility technology upgrades and enhanced cleaning. However, the above 3 problems are still a problem; that is, although the toilet bowls and urinals in public toilets can ensure effective flushing after using the toilet, due to the dense traffic of people using the toilet, it is inevitable that a certain amount of feces and urine will remain attached after flushing. The accumulation of feces and urine left after using the toilet with dense traffic makes the toilet area, especially the urinal area, have a strong odor that is unbearable.

[0003] The purpose of the utility model is to overcome the above-mentioned defects of the prior art and provide a device for adding an auxiliary agent into a flushing pipeline of a public toilet.
[0004] In order to achieve the above-mentioned purpose, the utility model is a device for adding an auxiliary agent to the flushing pipeline of a public toilet. The special feature of the device is that the flushing water source pipe of the public toilet is connected in series with a main venturi tube from upstream to downstream. The suction pipe mouth of the main venturi tube is downwardly connected to the main adding vertical pipe with a one-way valve at the bottom of the flushing aid liquid storage tank or the flushing aid dilution liquid storage tank. The main adding vertical pipe is provided with a manual valve or an electric control valve. The flushing aid is a toilet flushing aid with a deodorizing effect. The toilet flushing aid can be a liquid dosage form, a liquid dosage form after dilution with water, or a solid dosage form dissolved in water. The one-way valve on the main adding vertical pipe can allow the upward suction water flow to pass smoothly, and can also prevent the water in the flushing water source pipe from flowing downward in the non-flushing and upward suction state. The suction through the venturi tube is better than the usual mixing quality and efficiency, and it is more convenient to adjust the adding ratio by the opening of the electric control valve (which can also be a manual valve). In this way, after the public toilet has been running for a certain period of time, the manual valve or the electric control valve can be opened to allow the public toilet flushing water source pipe to absorb the flushing aid or flushing aid dilution from the flushing aid storage tank or the flushing aid dilution tank through the main venturi tube during flushing, thereby achieving enhanced flushing and deodorization effects. Because toilets will only emit strong odors when feces and urine residues, especially urine residues, accumulate to a certain level. Therefore, such phased addition of flushing aid can not only prevent public toilets from emitting strong odors, but also reduce the environmental impact of flushing aids through intermittent addition, and reduce the burden of water treatment. It has the ability to open the suction pipeline as needed, and automatically add flushing aid or its dilution by relying on the water flushing force flowing through the public toilet flushing water source pipe, ensuring high-quality and efficient addition while achieving intermittent enhanced flushing and deodorization of the toilet, especially removing feces and urine residues, achieving the effect of saving toilet flushing water and preventing odor.
[0005] As an optimization, the manual valve is extended with a manual rod for easy operation; the electric control valve is electrically connected to a light indicating the manual switch, so that the switch status can be clearly observed.
[0006] As an optimization, the electric control valve is electrically connected to a controller for a manual switch with an indicator light, and the controller is equipped with a wireless communication module for wireless communication with a smart terminal. This allows for manual opening and closing, as well as close-range on-site control or remote off-site control via a smart terminal.
[0007] As an optimization, the upstream section of the Venturi tube in the public toilet flushing water source pipe is connected via a tee to the water supply pipe that fills the flushing aid diluent storage tank. This supply pipe is equipped with a float valve to control the flushing aid diluent tank level, or a float valve and a shut-off valve to control the flushing aid diluent tank level. The flushing aid diluent tank is equipped with a flushing aid injection mechanism. This automatically meets the flushing aid dilution needs. When the shut-off valve is closed, the manual valve or electronic control is opened. Once the flushing aid diluent tank is empty, air-water mixed flushing can begin.
[0008] As an optimization, the flushing aid adding mechanism is a liquid flushing aid input mechanism or a solid flushing aid dissolving mechanism or a liquid flushing aid input mechanism and a solid flushing aid dissolving mechanism. This makes it easy to select the appropriate one.
[0009] As an optimization, the liquid flushing aid input mechanism of the flushing aid dilution liquid storage tank is a water supply pipe connected in series with a branch Venturi tube at the downstream section of the float valve, and the suction pipe mouth of the branch Venturi tube is connected to the auxiliary inlet vertical pipe with a one-way valve extending into the bottom of the liquid flushing aid storage tank. The liquid flushing aid storage tank is configured on one side of the flushing aid dilution liquid storage tank or is set independently; this can automatically meet the needs of automatic dilution of the liquid aid.
[0010] The solid flushing agent dissolving mechanism of the flushing agent diluent storage tank is to configure the flushing agent diluent storage tank with a convenient access to the solid flushing agent to be dissolved block immersion cage. This can automatically meet the needs of automatic dilution of solid additives.
[0011] As an optimization, the liquid flushing aid storage tank is a transparent container for observing the liquid level or a container equipped with a liquid level display tube, which is convenient for observing the liquid level; the wall of the flushing aid dilution liquid storage tank is sealed with a glass perspective window at the height of the solid flushing aid block to be dissolved immersion cage, which is convenient for observing the dissolution of the flushing aid block to be dissolved.
[0012] As an optimization, the immersion cage for the solid flushing aid blocks to be dissolved is connected upward to an inverted U-shaped buckle rod that is used to invert the upper open flushing aid diluent storage tank. The liquid flushing aid input mechanism of the flushing aid diluent storage tank consists of a liquid flushing aid input mechanism and a solid flushing aid dissolving mechanism. A manual flushing aid diluent valve is installed on the secondary mixing vertical pipe. In this way, when the liquid flushing aid input mechanism needs to be deactivated, the manual flushing aid diluent valve can be easily closed to ensure the use of the solid flushing aid dissolving mechanism alone. This is because most liquid flushing aids should not be mixed with solid flushing aids.
[0013] As an optimization, a handle is provided at the lower end of the outer vertical arm of the inverted U-shaped buckle rod for easy taking and placing.
[0014] As an optimization, filters are installed at the lower ends of the main and auxiliary vertical pipes to prevent the ingestion of foreign matter that could affect the operation of the venturi tube. The main vertical pipe is also equipped with a shutoff valve electrically connected to a controller. This valve is electrically connected to a controller with a manual switch and an indicator light. The controller is equipped with a wireless communication module for connecting to a smart terminal. Closing this shutoff valve allows for air-water mixing and flushing.
[0015] In short, the device for adding additives of the utility model can be started automatically, manually, or remotely. While reducing the labor intensity of cleaning staff, it improves the air quality of public toilets and enhances the appearance quality of toilets. 1. During operation, the toilet flushing water source pipe draws in the flushing additive through the main venturi tube, flushing the toilet with high quality and efficiency, which has the effect of removing scale, preventing scale, and deodorizing. 2. The suction of flushing additives is opened and closed by the electric control valve provided in the main adding vertical pipe. The controller of the manual switch with light display and the wireless communication module configured for wireless connection to smart phones can be electrically connected to the electric control valve to realize remote control and setting of automatic intermittent opening and closing. 3. It is suitable for direct addition of liquid flushing additives, and also for addition of solid flushing additives after dissolution. It is more suitable for indirect addition of liquid flushing additives after pre-dilution. 4. Public toilets are flushed with additives 2-3 times a day, and liquid flushing additives are injected or solid flushing additives are added each time. After flushing with the additives for one day, the toilet can be kept clean for about a week without emitting a strong odor. 5. Under the conditions of normal flushing without auxiliary agents and the flushing auxiliary agent dilution liquid tank or the flushing auxiliary agent tank being emptied, you can also open the electric control valve or manual valve set on the main adding vertical pipe and close the electric control valve on the main adding vertical pipe, so that the public toilet flushing water source pipe can inhale air through the main adding vertical pipe, implement air-water mixed flushing, and rely on the mixed air pressure to increase the impact force of the water flow, which can further save water while ensuring the flushing effect.
[0016] After adopting the above technical solution, the utility model has the function of opening the suction pipeline as needed, and automatically adding the flushing aid or its diluent by relying on the water force flowing through the public toilet flushing water source pipe, thereby ensuring high-quality and efficient addition, and realizing intermittent enhanced flushing and deodorization of the toilet, especially removing feces and urine residues, thereby achieving the effect of saving toilet flushing water and preventing odor.
