Description

Technical Field

[0001] This invention, a piston-type toilet, belongs to the field of people's livelihood, including renewable resource recycling, water conservation, and emission reduction. Background Technology

[0002] Currently, the widespread use of flush toilets in cities not only consumes a large amount of domestic water but also wastes valuable organic fertilizer resources and pollutes the environment. In rural areas, most still use outdoor dry toilets, impacting the quality of life. Invention patent 201510125303.0 discloses a toilet with a two-stage piston system for expelling feces. However, practical experience has shown that this technology has the following drawbacks: 1. The two-stage piston and rotating brush device have a complex structure and are difficult to manufacture; 2. An additional air compressor is required; 3. The joint between the two-stage expulsion cylinders is exposed, making it impossible to effectively remove residual feces; 4. It cannot eliminate odors. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide people with a series of piston-type toilets that are clean, odorless, compact in structure, and capable of both mixing and recycling pure human feces and urine, as well as recycling pure human feces and urine separately, and have a wide range of applications.

[0004] The technical solution of the piston toilet of the present invention includes a seated piston toilet, a squatting piston toilet, and a high-pressure piston toilet.

[0005] 1. Piston toilet. This toilet consists of a gas and water supply system, a toilet bowl, a bidet, a piston-like discharge mechanism, a frame, an odor control system, and a noise reduction method.

[0006] 1.1 Gas and water supply device. This device consists of a silent air pump, an air storage tank, and a water storage tank.

[0007] 1.1.1 Silent Air Pump. The silent air pump of this invention is a modified application of a refrigerator compressor. It is located in the middle of the upper part of the air storage tank, and its function is to silently supply compressed air.

[0008] 1.1.2 Air tank. This air tank is located horizontally at the foot of the toilet bowl. Its function is to store compressed air, and it is equipped with a pressure gauge, pressure switch, and main air control valve.

[0009] 1.1.3 Water Storage Tank. Located below the air tank, the water storage tank functions to provide toilet water at a suitable temperature and pressure. The tank's structure includes an inlet, an outlet, a pressure-limiting micro-pump, an electric thermostat, and an insulation layer.

[0010] 1.2 Toilet bowl. The toilet bowl is made of anti-corrosive and self-lubricating materials. Its upper end is equipped with a flat plate and a toilet seat. At the front end, there are 1 - 3 high-pressure fan-shaped nozzles for cleaning the toilet bowl. At the rear end side, there is a smell discharge outlet, and at the rear end of the bottom, there is a feces outlet. The toilet seat is composed of an end cover and a seat ring. The seat ring is a hollow body, and there are two upper and lower water pipes at the rear. The water pipes are connected to the water storage bucket at the tail, that is, by using the gravity circulation effect generated by the water temperature difference, the constant temperature of the appropriate temperature of the toilet seat ring is achieved.

[0011] 1.3 Post-defecation rinser. The post-defecation rinser is located in the upper middle position at the rear of the feces outlet, and its function is to rinse the residues on the buttocks. Its structure is composed of a telescopic spray pipe, a micro magnetic cylinder, and supporting electrical components.

[0012] 1.3.1 Working procedure and principle of the post-defecation rinser. After defecation, start the electric control switch → the five-way solenoid valve works → the micro magnetic cylinder drives the telescopic spray pipe to an appropriate position → the magnetic switch located outside the micro magnetic cylinder is started under the action of the piston magnetic ring → the electromagnetic water valve is started → the spray holes located at the upper front end of the telescopic spray pipe spray warm water from the water storage bucket to rinse the buttocks → after rinsing, close the electric control switch, and the telescopic spray pipe stops watering and returns to its original position.

[0013] 1.4 Piston defecation device. This device is located at the bottom of the toilet bowl. Its function is to receive and discharge feces. Its structure is composed of: a gate valve, a three-way defecator, and supporting electrical components.

[0014] 1.4.1 Gate valve. The gate valve is connected to the toilet bowl outlet. Its function is to seal the feces inlet, prevent liquid splashing and odor overflow. Its structure is composed of a gate valve housing, a switch gate plate, a gate valve cylinder, and electrical components supporting the cylinder. Its switching procedure is linked with the following "three-way defecator".

[0015] 1.4.2 Three-way defecator. The inlet of the three-way defecator is connected to the outlet of the above gate valve. Its structure is composed of: a three-way cylinder barrel, a port sealing plate, a defecation magnetic cylinder, a defecation piston, a check valve, and electrical components supporting the cylinder. Its working principle is: the front and rear ports of the three-way cylinder barrel are sealed by the port sealing plate. The front port sealing plate is a movable part that is easy to disassemble and is also the carrier for connecting the defecation magnetic cylinder to the three-way cylinder barrel. At an appropriate position outside the defecation magnetic cylinder, there is a magnetic switch for controlling the gate valve; the cylinder expansion rod passes through the front port sealing plate and is connected to the pushing feces piston arranged in the three-way cylinder barrel body, so as to realize that the expansion rod of the cylinder drives the defecation piston to do repeated defecation movements in the three-way cylinder barrel body. There is a feces outlet on the rear sealing plate of the three-way cylinder barrel, and a check valve is connected to the outer end of the outlet.

[0016] 1.4.3 Working Procedure and Principle of the Piston Defecation Device. The main power switch is activated → the five-way solenoid valve operates → the telescopic rod of the magnetic cylinder drives the defecation piston to retract to its rear stop point → the gate valve magnetic switch is activated → the five-way solenoid valve operates → the telescopic rod of the gate valve with magnetic cylinder drives the switch gate → the gate valve opens; after defecation, the main power switch is closed → the five-way solenoid valve operates in reverse → the magnetic defecation cylinder drives the defecation piston to move towards the outlet → the gate valve magnetic switch closes due to loss of magnetic field → the five-way solenoid valve operates in reverse → the gate valve closes → the telescopic rod of the magnetic defecation cylinder drives the defecation piston, which pushes the feces, forcefully pressing the feces into the output pipe through the check valve.

[0017] 1.5 Frame. The function of this frame is to support and connect related components. Its exterior is fitted with a protective panel, enclosing the toilet into a complete box.

[0018] 1.6 Odor Exhaust Device. The main component of this device is a "small duct exhaust fan." The air inlet of the "small duct exhaust fan" is connected to the odor exhaust outlet of the toilet bowl via a duct, and the air outlet is connected to the output duct leading to the outside. The start and stop of the exhaust fan are synchronously controlled by the toilet's "main power switch."

[0019] 1.7 Noise Elimination Methods. 1. The method to eliminate air pump noise is to modify the refrigerator compressor into a "silent air pump". 2. The method to eliminate noise generated by the exhaust of the "five-way solenoid valve" is to connect all the exhaust ports of the "five-way solenoid valve" in parallel into a single pipeline connected to the outside using multi-hole fittings, and install a silencer at the end of the pipeline.

[0020] 2. Squat piston toilet. The technical solution of the squat piston toilet of this invention includes a feces and urine mixing squat piston toilet and a feces and urine separating squat piston toilet.

[0021] 2.1 Mixed-Urine Squat Piston Toilet. This type of toilet is mostly used in communal toilets consisting of multiple toilets. Therefore, each toilet has its own gas and water supply system (in apartment buildings, multiple floors can share one gas and water supply system), and gas and water are supplied to each toilet through pipelines. The squatting basin is basically the same as that of a traditional water-flushing squat toilet, the difference being that the front of the basin is equipped with 1-2 fan-shaped cleaning nozzles. The flushing device, fecal discharge device, odor removal device, and noise reduction method at the rear and bottom of the basin are all the same as those of a seated piston toilet.

[0022] 2.2 Fecal-Urine Separation Squat Toilet with Piston Function. The special function of this toilet is to store and recycle feces and urine separately. Feces are used to produce organic fertilizer, and urine is used to extract urokinase and produce liquid fertilizer. Its structural features include a fecal-urine separation chamber pot and a two-section telescopic water brush. Its post-defecation cleaning device, piston-type expulsion device, odor removal device, and noise reduction method are all the same as the aforementioned seated piston toilet. Its air and water supply methods are also the same as the aforementioned fecal-urine mixed squat toilet with piston function.

[0023] 2.2.1 Urine and feces isolation chamber pot. The chamber pot is divided into two parts, front and back. The front part is a trough-shaped body for receiving urine, with a urine discharge hole at the bottom, which is connected to a urine storage tank through a pipeline. The rear part of the chamber pot is a circular feces inlet, which is equipped with a "post-defecation cleaning device" and a "piston discharge device" connected to the bottom.

[0024] 2.2.2 Two-section telescopic water brush. Designed to shorten its length, the two-section telescopic water brush is normally in a retracted state and hidden in the back of the toilet. Its function is to spray water 360 degrees to clean the fecal inlet. Its structure consists of two telescopic tubes and a rotating nozzle.

[0025] 2.2.2.1 Two-section telescopic tube. This two-section telescopic tube consists of three sets of square tubes with matching diameters. The outer square tube is a fixed tube, the middle square tube is a telescopic tube, and the inner square tube is a two-section telescopic tube. The extension and retraction of the first telescopic tube is driven by a matching ordinary miniature cylinder, and the extension and retraction of the second telescopic tube is driven by a matching miniature magnetic cylinder.

[0026] 2.2.2.2 Rotary Sprayer. This rotary sprayer consists of a miniature geared motor and a high-pressure fan-shaped nozzle, located at the front end of the two-section telescopic pipe, and connected to an electromagnetic water valve via a flexible hose. The spraying is automatically controlled by a magnetic switch located outside the miniature magnetic cylinder.

[0027] 2.2.2.3 The working procedure of the two-section telescopic water brush is as follows: the timer switch is started → the five-way solenoid valve shared by the two cylinders supplies air to the two cylinders → the two cylinders drive the first and second sections of the telescopic tube to carry the rotating nozzle to the upper center of the fecal inlet → the magnetic switch with the magnetic cylinder is started → the solenoid water valve is started → the rotating nozzle rotates 360 degrees and sprays a high-pressure fan-shaped water curtain → the timer ends → the rotating nozzle stops water flow → the telescopic tube retracts, carrying the rotating nozzle back to its original position.

[0028] 3. High-Pressure Piston Toilet. This invention's high-pressure piston toilet can be manufactured as a squat toilet or a seated toilet, suitable for use in submarines and similar environments. Its technical solution is basically the same as the aforementioned seated piston toilet, with the following differences: 1. The three-way cylinder and piston sealing ring of the piston expulsion device must be made of materials suitable for its high-pressure environment. 2. The expulsion piston is driven by a hydraulic cylinder. 3. A hydraulic high-pressure shut-off valve is installed at the outer end of the check valve of the expulsion pipe, equipped with a corresponding automatic pressure switch. That is, when the toilet's expulsion pressure exceeds the specified external water pressure, the hydraulic high-pressure shut-off valve automatically opens and automatically closes after expulsion. 4. The odorous gas discharged by the duct exhaust fan is deodorized by a filter before being released indoors.

[0029] The present invention has the following advantages:

[0030] 1. The piston-type toilet of this invention adopts a gate valve for sealing, a high-pressure fan-shaped nozzle for flushing, and a ventilation fan duct for odor removal and noise elimination, ensuring that the toilet is clean, odorless, and operates quietly.

[0031] 2. The piston-type toilet of this invention is suitable for any place where human activity takes place, and is especially advantageous in areas where fresh water is scarce.

[0032] 3. The piston-type toilet of this invention can achieve 100% pure recycling of human excrement and urine, providing unlimited resources for organic fertilizer production, which is of great significance to current soil remediation, ecological agriculture and food safety.

[0033] 4. The water consumption of the piston-type toilet of this invention is limited to flushing the toilet bowl and washing the buttocks, with a water consumption of only about 0.3 liters per flush. Compared with the 6-8 liters of water consumption per flush toilet, it saves more than 90% of water, and the water-saving effect is significant.

[0034] 5. The toilet piston of the present invention integrates the toilet and the gas and water supply device into one unit, providing convenience for rural toilets to be installed indoors and in places with insufficient water pressure.

[0035] 6. The feces and urine isolation squat toilet of the present invention can simultaneously obtain the benefits of urine recycling and feces recycling, which can effectively reduce recycling costs.

[0036] If the high-pressure piston toilet of this invention can be applied to submarines, it can discharge feces at any depth underwater. Compared with the current negative pressure storage method, it is simpler, more reliable, and saves space. Attached Figure Description
