Description

Technical Field

[0001] This utility model belongs to the field of lifting toilet technology, specifically a photovoltaic lifting and circulating water self-cleaning toilet device for scenic areas. Background Technology

[0002] Currently, many large scenic areas suffer from significant deficiencies in restroom facilities. On the one hand, the number of restrooms is insufficient to meet visitor needs, primarily due to the difficulty of maintenance and high construction costs. On the other hand, the number of handwashing basins within the scenic areas is also limited, and there is serious waste in the treatment of wastewater from these basins. Most existing scenic area restrooms simply discharge wastewater directly to sewage treatment centers through drainage networks, failing to fully utilize the usable properties of this wastewater and resulting in a substantial waste of resources.

[0003] While some progress has been made in the research of lift-up toilets in the existing technology, there are still many shortcomings. For example, the anti-fall underground toilet device with patent number CN208088895U, although it solves the problem of sewage backflow by using a movable sealing hose, is prone to aging of the sealing ring and is difficult to use stably for a long time.

[0004] A similar lifting toilet with patent number CN208088895U, although using a axial hydraulic device to achieve toilet lifting, is prone to clogging due to the use of conventional squat toilet facilities, which not only affects long-term use but also has aesthetic problems.

[0005] In addition, a smart lifting toilet with patent number CN201144454Y lifts the toilet by linking a motor and a coin-operated device, and its excretion device is transferred and connected via a conduit. However, the conduit is prone to aging and is also difficult to meet the needs of long-term use.

[0006] Existing technologies for lift toilets have the following main drawbacks:

[0007] First, there is the issue of power dependence: current technologies cannot achieve self-lifting functionality and must rely on external electricity for power. In complex environments such as large scenic spots, this not only increases the construction and maintenance costs of power facilities, but may also affect the normal use of the restrooms due to unstable power supply.

[0008] Secondly, there are defects in the lifting mode: existing technologies mostly adopt the mode of lifting the toilet squatting toilet and the box together. This mode has extremely high requirements for the connection of the sewage pipe. In actual use, it is difficult to guarantee long-term stable operation and effective maintenance, and problems such as connection failure are prone to occur, which in turn affect the normal use of the entire toilet.

[0009] Third, there is a lack of resource recycling: current technologies do not address the recycling of cleaning wastewater and rainwater. In areas such as scenic spots where water demand is high and water resources are relatively precious, the failure to fully utilize these water resources results in unnecessary waste and is detrimental to the sustainable development of these areas.

[0038] The following is combined Figures 1-5 This utility model will be described in detail.

[0039] Example

[0040] like Figures 1-5 As shown, a photovoltaic lifting and circulating water self-cleaning toilet device for scenic spots is characterized by comprising a toilet body, a photovoltaic power generation module, a lifting module, a pneumatic module, and a water circulation module.

[0041] The main body of the toilet includes a toilet base 014 installed on the flat ground 009 of the scenic area. A toilet squatting toilet 105 is installed on the toilet base 014. A first lifting support rod 110, a second lifting support rod 109, and two toilet support rods 004 are installed outside the toilet base 014. A toilet ceiling 003 is installed above the toilet base 014. One end of the first lifting support rod 110, the second lifting support rod 109, and the two toilet support rods 004 are fixed to the bottom of the toilet ceiling 003, and the other end is connected to the lifting module. A photovoltaic power generation module is installed on the top of the toilet ceiling 003. The lifting module is connected to the pneumatic module, and the pneumatic module is connected to the water circulation module. The water circulation module and the pneumatic module are located in the pit under the flat ground 009 of the scenic area. A toilet water tank 104 is also installed on one side of the toilet squatting toilet 105. One side of the toilet water tank 104 is connected to the outlet of the water circulation module. The inlet of the water circulation module is connected to the washbasin 012 installed on the flat ground 009 of the scenic area through a drain pipe 101. The toilet squatting toilet 105 is connected to the toilet sewage pipe 106 and connected to the outdoor sewage pipe network 333.

[0042] like Figure 2 As shown, the photovoltaic power generation module includes a solar photovoltaic panel 001 installed on the top of the bathroom ceiling 003 via a photovoltaic panel bracket 002. The solar photovoltaic panel 001 is electrically connected to an energy storage battery 007 installed on the top of the bathroom ceiling 003. The energy storage battery 007 is electrically connected to a control pile 013 installed on the flat ground 009 of the scenic area via a second wire 335.

[0043] The solar photovoltaic panel 001 converts solar energy into electrical energy, which is stored in the energy storage battery 007 to power the entire device. This solves the problem of relying on external power in existing technologies, reduces the construction and maintenance costs of power facilities, and improves the stability of the toilet's use. The control post 013 is equipped with up and down buttons, which are electrically connected to the energy storage battery 007 via wires to control the raising and lowering of the toilet.

[0044] like Figure 4 As shown, the lifting module includes a lifting motor box 006. Inside the lifting motor box 006, a motor drive gear 328 is installed, which is electrically connected to the energy storage battery 007 via a first wire 334. Driven gears 327 are meshed above and below the motor drive gear 328. The driven gears 327 mesh with the concave teeth on the toilet support rod 004. The toilet support rod 004 is slidably connected to the limiting hole 329 on the lifting motor box 006. A first lifting sleeve 107 and a second lifting sleeve 108 are installed in the pit under the scenic flat ground 009. The first lifting support rod 110 is installed inside the first lifting sleeve 107, and the second lifting support rod 109 is installed inside the second lifting sleeve 108.

[0045] The lifting module is also equipped with a limit component, which includes a positioning rod 325 and a positioning gear 326 electrically connected to the energy storage battery 007 via a first wire 334. The positioning gear 326 is meshed with the positioning rod 325. The positioning rod 325 is slidably installed at the bottom of the lifting motor box 006. The toilet support rod 004 and the cylinder connecting rod 319 are provided with limit holes that are inserted and cooperate with the positioning rod 325.

[0046] The lifting motor box 006 is also equipped with an auxiliary force-bearing wheel 330 that meshes with the concave teeth on the toilet support rod 004, which improves the stability and uniformity of force during the lifting process.

[0047] In the specific implementation process, it is worth noting that, in order to reduce friction during the lifting process, pulleys can be provided on the inner side of both the first lifting sleeve 107 and the second lifting sleeve 108. This is existing technology and will not be elaborated on here.

[0048] The motor's driving gear 328 rotates clockwise, causing the driven wheel 327 to rotate counterclockwise. The counterclockwise rotation of the driven wheel 327 pulls the bathroom support rod 004 upwards through the limiting hole 329. The bathroom support rod 004 has teeth engraved on it that correspond to the driven wheel 327 and the auxiliary force-bearing wheel 330. When the bathroom support rod 004 reaches the limited position, the positioning gear 326 activates and rotates counterclockwise, causing the positioning rod 324 to limit the movement of the bathroom support rod 004, and the power is turned off.

[0049] like Figure 2 and Figure 4As shown, the water circulation module includes a sewage treatment tank 102 connected to a drain pipe 101. A clean water tank 103 is located below the sewage treatment tank 102. The sewage treatment tank 102 has a drainage ditch 303, an upper filter chamber 305, a filter screen 306, and a lower filter chamber 307 arranged from top to bottom. The clean water tank 103 has a clean water chamber 310 and a pressurized water chamber 313 arranged inside.

[0050] The drain pipe 101 of the washbasin 012 is connected to the drain ditch 303 through the one-way drain valve 302. The drain ditch 303 is connected to the upper filter chamber 305 through the floating plug pipe 336. The upper filter chamber 305 is connected to the lower filter chamber 307 through the filter screen 306. The lower filter chamber 307 is connected to the clean water chamber 310 through the fourth one-way valve 308. The circulating clean water 311 in the clean water chamber 310 enters the pressurized water chamber 313 through the drain hole 312. The pressurized water chamber 313 is connected to the toilet water tank 104 through the third one-way valve 321.

[0051] A drainage grate 301 is provided on the drainage ditch 303 to prevent debris from entering the drainage ditch. A floating plug 304 is provided inside the floating plug pipe 336. The floating plug pipe 336 is closed by the floating ball connected to it, thus limiting the water level from overflowing.

[0052] The water circulation module also includes an overflow prevention chamber 324 for preventing overflow and compressing air. This chamber is connected to the cylinder 318 via a first overflow prevention hole 322 and to the upper filter chamber 305 via a second overflow prevention hole 323. Outside air enters the drain ditch 303 through the drain grate 301, then enters the upper filter chamber 305 through the floating plug pipe 336, enters the overflow prevention chamber 324 through the second overflow prevention hole 323, and finally enters the cylinder 318 through the first overflow prevention hole 322. Subsequently, when the bathroom support rod 004 moves upward, it drives the cylinder connecting rod 319 to move upward. The upward movement of the cylinder connecting rod 319 reduces the internal volume of the cylinder 318, thereby increasing the air pressure within the cylinder 1318. A first one-way valve 316 at one end of the cylinder connecting rod 319 is designed to allow air to flow only from the cylinder 318 to the compression chamber 315, while preventing reverse airflow.

[0053] In addition, the first overflow hole 322 and the second overflow hole 323 also serve to prevent overflow. When the one-way valves in the pneumatic module and the water circulation module fail, they prevent the circulating purified water 311 in the purified water chamber 310 from entering the lifting motor box 006 and affecting the normal operation of the lifting module.

[0054] The water circulation module also includes a water level detection line, which is set on one side of the water purification chamber 310. When the water level is lower than the scale line, the water supply pipe directly supplies water to the water purification chamber 310 to prevent insufficient circulating water.

[0055] like Figure 4As shown, the pneumatic module includes a cylinder 318 installed below the lifting motor box 006, a cylinder connecting rod 319 installed inside the cylinder 318, one end of the cylinder connecting rod 319 being fixedly connected to the bathroom support rod 004, and the other end being equipped with a first one-way valve 316. The cylinder 318 is connected to a compression chamber 315 through the first one-way valve 316. The compression chamber 315 is connected to an enhanced compression chamber 314. The enhanced compression chamber 314 is connected to a water purification chamber 310 through a second one-way valve 309.

[0056] In the specific implementation process, it is worth noting that an anti-impact spring 320 is also installed inside the cylinder 318 to prevent the cylinder 318 from being subjected to excessive impact force during the lifting and lowering process.

[0057] When the bathroom support rod 004 moves upward, it drives the cylinder connecting rod 319 upward. The upward movement of the cylinder connecting rod 319 reduces the internal volume of the cylinder 318, thereby increasing the air pressure within the cylinder 1318. The first one-way valve 316 at one end of the cylinder connecting rod 319 is designed to allow air to flow only from the cylinder 318 to the compression chamber 315, preventing reverse air flow. When the cylinder connecting rod 319 moves upward, the air pressure within the cylinder 1318 increases, forcing the first one-way valve 316 to open, allowing compressed air to enter the compression chamber 315. The compression chamber 315 is connected to the enhanced compression chamber 314; after entering the compression chamber 315, the air further fills the enhanced compression chamber 314. These two chambers store compressed air during the upward movement, providing power for the subsequent downward movement.

[0058] When the user presses the "down triangle" button on the control post 013, the energy storage battery 007 activates the positioning gear 326 via the wire 334. The positioning gear 326 rotates clockwise, causing the positioning rod 324 to unlock the bathroom support rod C004. Simultaneously, the motor drive gear 328 rotates counterclockwise, causing the driven wheel 327 to rotate clockwise, pulling the bathroom support rod 004 downward. As the bathroom support rod 004 moves downward, it drives the cylinder connecting rod 319 downward. When the cylinder connecting rod 319 moves downward, the first one-way valve 316 at one end closes to prevent air from flowing backward in the cylinder 318. During the ascent, high-pressure air is stored in the compressed air chamber 315 and the enhanced compressed air chamber 314. When the cylinder connecting rod 319 moves downward, this high-pressure air needs to be released to assist the descent. High-pressure air in compressed air chamber 315 and enhanced compressed air chamber 314 enters clean water chamber 310 through second check valve 309 of air chamber 310 to pressurize the circulating clean water 311 in clean water chamber 310.

[0059] The pressurized circulating purified water 311 enters the pressurized water chamber 313 through the drainage hole 312, and then enters the toilet squatting toilet 105 through the third one-way valve 321 to complete the toilet cleaning action. This process not only achieves the descent of the toilet, but also utilizes the stored high-pressure air to complete the toilet cleaning action, improving the overall efficiency of the system.

[0060] A bathroom partition 005 is installed between two adjacent bathroom support rods 004, between the bathroom support rod 004 and the first lifting support rod 110, and between the bathroom support rod 004 and the second lifting support rod 109.

[0061] The bathroom partition 005 consists of a lower partition 201, a steel wire 202, a flexible metal partition 203, and an upper partition 204. The lower partition 201 is fixed to the bathroom base 014, and the upper partition 204 is fixed to the bathroom ceiling 003. The bathroom partition 005 provides privacy, and the cooperation of the lower partition 201, steel wire 202, flexible metal partition 203, and upper partition 204 allows the bathroom partition 005 to stretch and change with the raising and lowering of the bathroom support rod 004.

[0062] In existing technology, it is similar in structure to a retractable sunshade. Retractable sunshades generally also have fixed components installed at the top and bottom of the building (similar to the lower baffle 201 and the upper baffle 204 fixed to the base and top plate respectively), and a retractable flexible blocking part in the middle (similar to a flexible metal baffle 203). The retraction and extension are coordinated by connecting components (similar to steel wire 202) to realize the opening and closing of the sunshade function. The bathroom baffle 005 adapts to the lifting and lowering of the bathroom support rod to achieve the opening and closing effect of privacy protection. The two are similar in that they cooperate to achieve a certain adjustable blocking or isolation function by connecting fixed components, flexible deformable components and connectors.

[0063] In addition, it is somewhat similar to the retractable curtain-type partition structure. The curtain-type partition has a frame installed at the top and bottom (similar to the lower baffle 201 and the upper baffle 204), and a retractable curtain part in the middle (similar to the flexible metal baffle 203). The curtain can be extended and retracted through a certain connecting structure (similar to the steel wire 202) to control the division of the area. It is similar in basic structural principle to the bathroom baffle 005, which adapts to the rise and fall of the support rod to stretch and change to control privacy protection.

[0064] The main body of the bathroom also includes a bathroom sliding door 008, which is fitted into the second lifting support rod 109. The pulley at the lower end of the bathroom sliding door 008 is placed on the slide rail of the bathroom base 014 to realize the opening and closing of the bathroom.

[0065] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
