Description

Technical Field

[0001] The present invention relates to the field of manufacturing sanitary equipment, and in particular to a toilet manufacturing process with multiple functional improvements and its flushing system. Background Art

[0002] Traditional toilets have obvious deficiencies in many aspects, seriously affecting the user experience. First of all, the flushing effect is poor, which is a common problem. Most traditional toilets adopt a single flushing method and cannot be flexibly adjusted according to different types of excrement and dirt, resulting in incomplete flushing or waste of water resources. For example, for stubborn stains or feces, insufficient flushing volume is difficult to thoroughly wash away; while when the flushing volume is too large, it is easy to cause waste of water resources, which is particularly prominent in modern society where water resources are increasingly scarce.

[0003] Secondly, the cleaning convenience is poor. There are a large number of inaccessible dead corners on the inner wall of traditional toilets, such as internal and external corners, light and dark corners, and right angles. These parts are prone to accumulating dirt, which is not only time-consuming and laborious to clean, but also difficult to clean thoroughly even with various cleaning tools and chemical cleaners. Over time, it is easy to breed bacteria and generate odors, posing a threat to the health of users.

[0004] Furthermore, the use comfort is not good. The design of traditional toilets lacks sufficient consideration for the needs of different groups of people. For example, for special groups such as the elderly, the disabled, and children, there are no necessary auxiliary facilities such as handrails and footrests, resulting in many inconveniences during their use and even possible safety accidents.

[0005] Finally, the maintenance convenience is poor. The internal structure of traditional toilets is complexly designed. Once blockages or failures occur in key parts such as the S-shaped discharge pipe, cleaning and maintenance are extremely difficult, and professional personnel are often required for disassembly and repair, bringing great troubles and additional economic burdens to users. At the same time, the anti-backflow function of traditional toilets is insufficient, easily leading to sewage backflow, polluting the toilet environment, and affecting the quality of life of users.

[0006] In view of the many problems of traditional toilets in terms of flushing effect, cleaning convenience, use comfort, and maintenance convenience, the present invention comes into being. Summary of the Invention

[0007] The present invention aims to solve these defects and problems in the prior art, and provides a toilet manufacturing process and its flushing system integrating multiple practical functions, so as to improve the overall use experience and performance of the toilet.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A manufacturing process of a multi-functional toilet, comprising the following steps:

Make a sector turntable and its connecting pull rope, precisely assemble it with the connecting shafts of the foot pedals, the cover board and the seat cushion, adjust the tightness of the pull rope, and at the same time install a safety shield;

[0017] S8: Design a toilet footrest (Q1) along the front of the toilet base, make corresponding round holes (R1, R2, R3, R4, R5, R6) and bolts, nuts, anti-slip foot pads (K), fix the footrest to the toilet base through bolts, and install anti-slip foot pads on the surface of the footrest. For toilets that do not require the installation of a footrest under normal circumstances, use rubber caps to seal the round holes;

[0018] S9: Install liftable armrests (S) on both sides of the bottom of the toilet water tank.

[0019] Furthermore, when making the toilet, through the discharge port (J1) inside the toilet, the decontamination port (L) at the back, and the discharge port (J2) of the toilet base, perform high-quality glazing treatment on the entire inner wall of the toilet S-shaped pipe, so that the inner wall of the toilet S-shaped discharge pipe is smooth and delicate, and there is no blockage during flushing.

[0020] Furthermore, the toilet footrest (Q1) is 0.3-0.4 meters long in front, has a width consistent with the toilet base, and is 0.2 meters high. A concave surface is installed inward along the upper edge, and a non-slip foot pad (K) is installed on the concave surface.

[0021] Furthermore, a multifunctional toilet flushing system includes three drain valves (B1, B2, B3) in the toilet water tank, which correspond to small, medium, and large water volume flushing buttons (C1, C2, C3), respectively, and flushing holes (D1, D2) connected thereto. By pressing different flushing buttons, flushing functions with different water volumes and flushing methods are achieved. When the small water volume flushing button (C1) is pressed, water is discharged only from the upper flushing hole (D1), and the drainage volume is 300-500 ml and can be adjusted automatically. When the medium water volume flushing button (C2) and the large water volume flushing button (C3) are pressed, water is discharged from both the upper flushing hole (D1) and the lower flushing hole (D2).

[0022] Furthermore, it also includes a foot-operated flushing device, which has a groove on the outer lower part of the left side of the toilet water tank and extends to the toilet base, and three foot pedals (P1, P2, P3) are provided on the base, and three cylindrical pull rod pipes (H1, H2, H3) are provided on the left side of the drain valve in the toilet water tank, and pull rods are installed respectively, and the pull rod point positions are (G1, G2, G3), among which G1 is designed with a nut connected to the hand-pressed flush button pressure rod, G2 is the G1 to G2 and G2 to G3 pull rod connection points are right angles, G3 is provided with a circular hole and is connected to the circular hole on the foot pedal on the toilet base through a single ring or a single rope loop, the direction of the circular hole of G3 is parallel to the direction of the circular hole on the foot pedal, the bottom diameter of the pull rod pipe is 0.5 cm larger than the upper diameter, and the inner diameter of the pull rod pipe matches the outer diameter of the pull rod to reduce friction and realize the foot-controlled flushing function.

[0023] Furthermore, flush holes (D1) are provided around the upper opening of the inner wall of the toilet, and the water spray direction is clockwise with a slight downward angle. The hole spacing is 3-5 cm, and the water spray pressure is relatively low. It is used to moisten the inner wall of the toilet before use to prevent excrement from sticking. The flush hole (D1) is controlled by an independent drain valve and flush button to control the water supply. The flushing volume is 300-500 ml each time and the water volume can be adjusted automatically.

[0024] Furthermore, in the toilet, with the excrement drop point (I) as the center, the distance from the water spray outlet of the flushing hole (D2) is 3-4 cm, and the distance from the inner discharge outlet (J1) is 5-6 cm. The diameter of the water spray outlet of the flushing hole (D2) is not more than 3 cm, the water depth is 3-4 cm, the pipe diameter of the inner discharge outlet (J1) is 10 cm, the water depth is 10-11 cm, the water depth at the excrement drop point (I) is 5-6 cm, and the inner wall of the toilet is designed with a gentle slope structure from the flushing hole (D1) to the excrement outlet (J1), the slope angle is about 40 degrees horizontally, and the distance from the water spray hole (D2) to the discharge outlet (J1) is not more than 9 cm.

[0025] Further, the flushing holes (D2) in the toilet bowl directly face the discharge port (J1) along the inclined plane for siphon flushing, combined with the spiral flushing of the flushing hole (D1), to flush the deposits at the discharge port (J1) cleanly at one time and prevent the backflow of excrement and sewage.

[0026] Further, when pressing the medium water volume flushing button (C2) and the large water volume flushing button (C3), the water supply pipe diameter of the water spray nozzle of the upper flushing hole (D1) is changed to adjust the water spray volume of the D1 water spray nozzle, so that the water spray volume of the D1 water spray nozzle each time accounts for 25% of the total water volume, ensuring that the lower flushing hole (D2) has sufficient flushing force to flush the excrement cleanly at one time.

[0033] Figure 1 It is a schematic diagram of the implementation process of the manufacturing process of the multifunctional toilet in the present invention. Detailed Implementation Modes

[0034] Example:

[0035] (I) Implementation Modes of the Manufacturing Process

[0036] Select materials and manufacture the toilet body: According to the design requirements, select ceramic materials with excellent strength, hardness, and corrosion resistance to manufacture the toilet body, ensuring that the toilet has a sufficient service life and stable performance; during the manufacturing process, strictly control the shape design of the inner wall of the toilet, and carefully polish all angles into arcs to completely eliminate difficult-to-clean parts commonly found in the inner walls of traditional toilets, such as internal and external corners, light and dark corners, and right angles, thereby providing great convenience for subsequent cleaning and maintenance work.

[0037] Install the drain valve and flush buttons: At the corresponding positions in the toilet tank, install the small-volume drain valve (B1), medium-volume drain valve (B2), and large-volume drain valve (B3) according to the pre-set dimensions and layouts, and accurately install the small-volume flush button (C1), medium-volume flush button (C2), and large-volume flush button (C3) in precise matching. By finely adjusting the opening degree of the drain valve and the stroke of the flush button, achieve precise control of the flushing volume to meet the flushing requirements in different situations and achieve a water-saving and efficient flushing effect.

[0038] Manufacture the connection between the foot pedal rod and the water tank pressing rod: According to the design plan requirements, manufacture the foot pedal rod (F1, F2, F3) and the water tank pressing rod (E1, E2, E3), and make accurate and stable connections and fixations; during the installation process, pay attention to adjusting the length and connection angle of the rod, fully considering the adaptability of different toilet installation spaces and the operation convenience of users, ensuring smooth, natural, stable, and reliable actions during foot pedal flushing, providing users with diverse flushing method options, and enhancing the comfort of use.

[0039] Open the flushing holes and install the pipes: At the appropriate positions on the inner wall of the toilet, open the flushing holes (D1) according to the pre-set dimensions and angle requirements, and install the pipes connected to the small-volume drain valve (B1); through strict testing and adjustment, ensure that when pressing the C1 flush button, the water flow can accurately spray out from the D1 flushing hole and form a uniform water curtain with an appropriate coverage range, effectively wetting the inner wall of the toilet to prepare for preventing excrement adhesion and enhancing the cleaning effect of the toilet.

[0040] Design the gentle slope structure and set the flushing hole (D2): Based on the established design dimensions and position parameters, construct a gentle slope structure inside the toilet to guide excrement into the discharge port (J1); the design of this gentle slope structure fully considers the principles of fluid mechanics and the characteristics of excrement, enabling excrement to slide down the inclined plane towards the discharge port under the action of gravity; at the same time, reasonably set the spraying direction and flow rate of the flushing hole (D2) to accurately match the excrement falling point (I), so that when the excrement falls into the water surface, with the buoyancy of the water and the guiding effect of the inclined plane, the occurrence of splashing water can be effectively reduced, enhancing the comfort of users.

[0041] Opening a dirt removal port and manufacturing related components: At the top of the S-shaped sewage discharge pipe on the back of the toilet, carefully open a dirt removal port (L) with a diameter of 10 cm according to the design specifications, and manufacture a matching upper cover (M) with a rubber gasket (N); during the installation process, strictly ensure the sealing between the dirt removal port and the upper cover to prevent leakage of water and air; at the same time, during the toilet manufacturing process, finely polish the inner wall of the S-shaped sewage discharge pipe and apply a high-quality glaze to improve its smoothness, effectively reducing the possibility of dirt adhesion, facilitating subsequent cleaning and maintenance work, and extending the service life of the toilet.

[0042] Installing a foot pedal and manufacturing a foot control device: Open a groove under the right side of the toilet cover and seat cushion, extending to the toilet base; on the base, install foot pedals (P4, P5, P6, P7) according to the position and layout required by the design; carefully manufacture a sector turntable and its connecting pull rope, precisely assemble the sector turntable with the foot pedals and the connecting shafts of the cover and seat cushion, and finely adjust the tightness of the pull rope to ensure that the opening and closing actions of the foot-controlled cover and seat cushion are flexible and accurate; at the same time, install a safety shield to effectively prevent collisions and frictions during rotation, ensuring the safety of users and enhancing the reliability of use.

[0043] Designing and installing a toilet footrest: Along the front of the toilet base, design and manufacture a toilet footrest (Q1) according to ergonomic principles and design specifications, with a forward length of 0.3 - 0.4 meters, the same transverse width as the toilet base, and a height of 0.2 meters; design two round holes at the corresponding positions on both sides in front of the toilet, install a rubber nut in the left round hole (R3), ensure that the shape of the nut matches the design of the round hole, and fix the nut to prevent it from rotating; according to the position of the R2 round hole, open a round hole (R1) at the corresponding position on the footrest, use a bolt matching the nut in the R3 round hole to pass through the R1 round hole of the footrest, connect and tighten it with the nut from the R2 round hole to ensure that the footrest is firmly installed and avoid loosening; install a concave surface along the edge inward on the footrest, and install an anti-slip footpad (K) on the concave surface to provide a safe and comfortable stepping experience for users; for toilets that do not require the installation of a footrest under normal circumstances, use rubber caps with the same color as the toilet surface to seal the round holes (R2, R3, R5, R6), which not only keeps the appearance of the toilet beautiful and tidy but also facilitates daily cleaning and maintenance.

[0044] Installing a handrail: Install a liftable handrail (S) on both sides at the bottom of the toilet tank according to the position and layout required by the design, ensuring that the handrail can provide a stable supporting force during use, giving reliable safety protection to the elderly and those with inconvenient legs and feet; when not in use, the handrail can be easily lifted and stored, without affecting the normal use of the toilet and the utilization of the surrounding space, fully reflecting the humanized consideration of the design.

[0045] (II) Flushing System Embodiment

[0046] Cooperation between the drain valve and the flushing button: When the user needs to perform a small - volume flush, press the small - volume flushing button (C1). At this time, the connected small - volume drain valve (B1) opens, and the water flows out only from the upper flushing hole (D1). The drainage volume is controlled between 300 - 500 milliliters, and the user can adjust the flushing volume according to the actual situation. When a medium - volume or large - volume flush is needed, press the medium - volume flushing button (C2) or the large - volume flushing button (C3) respectively. The corresponding medium - volume drain valve (B2) or large - volume drain valve (B3) opens, and the water will flow out from both the upper flushing hole (D1) and the lower flushing hole (D2) simultaneously, forming a strong flushing water flow that can effectively remove stubborn dirt in the toilet and ensure the cleanliness and hygiene inside the toilet.

[0047] Application of the pedal - type flushing device: If the user chooses the pedal - type flushing method, the foot can be placed on the corresponding pedal (P1, P2, P3) at the lower groove outside the left - hand side water tank of the toilet. When the foot steps on the pedal, the pedal is connected to the pedal pull rod (G3) through a round hole, and then drives the pull rod to move inside the cylindrical pull - rod pipe (H1, H2, H3). Since the bottom diameter of the pull - rod pipe is 0.5 cm larger than the upper diameter, and the inner diameter of the pull - rod pipe matches the outer diameter of the pull - rod, this design can effectively reduce the friction when the pull rod moves inside the pipe and ensure the smoothness of the pedal action. Subsequently, the movement of the pull rod is transmitted to the pressing lever (E1, E2, E3) inside the water tank through the connection points (G1, G2), and then controls the opening of the drain valve (B1, B2, B3), realizing the flushing function with the same effect as pressing the hand - held flushing button, providing the user with a more convenient, hygienic and diversified flushing option, especially suitable for the situation where the user has something in hand or is inconvenient to operate with hands.

[0048] Realization of the anti - adhesion function of the flushing hole (D1): Before each use of the toilet, the user first presses the small - volume flushing button (C1) to open the connected drain valve (B1), and the water then sprays out from the flushing hole (D1) opened around the inner wall of the toilet. The spraying direction of the flushing hole (D1) is designed to have a clockwise and slightly downward angle, the hole spacing is 3 - 5 cm, and the spraying pressure is kept at a relatively small level. This design aims to make the water flow evenly cover the inner wall of the toilet, forming a water film, so that a large number of water droplets can stay on the inner wall of the toilet. When excrement falls into the toilet, since the inner wall is already covered with water droplets, sticky substances and sticky liquids are not easily adhered to the inner wall of the toilet, and naturally no difficult - to - clean dirt marks will be left, effectively reducing the difficulty and frequency of cleaning work and keeping the toilet clean for a long time.

[0049] Implementation mechanism of splash-proof function: In the internal structure design of the toilet, with the excrement falling point (I) as the center, accurately control the distance between the flushing hole (D2) and the excrement falling point (I) to be about 3 - 4 cm, and the distance between the inner discharge port (J1) and the excrement falling point (I) to be 5 - 6 cm; at the same time, design the diameter of the water spray nozzle of the flushing hole (D2) to be no more than 3 cm, the water depth to be 3 - 4 cm, while the pipe diameter of the inner discharge port (J1) is set to 10 cm, the water depth to be 10 - 11 cm, and the water depth at the excrement falling point (I) is controlled at 5 - 6 cm; in addition, the inner wall of the toilet from point D1 to the excrement outlet (J1) adopts a gentle slope structure design, the slope angle is about 40 degrees horizontally, and the distance from the water spray nozzle of the flushing hole (D2) to the discharge port (J1) is no more than 9 cm; through this carefully designed size and structural layout, when the excrement falls into the water surface, it can smoothly slide into the discharge port (J1) under the buoyancy of the water and the guiding effect of the inclined plane. Even when encountering blocky excrement, it can effectively avoid water splashing, improve the comfort of users, reduce the diffusion of odors, and create a more hygienic use environment.

[0050] Implementation of anti-backflow and anti-blockage functions: Inside the toilet, with the position of the excrement falling point (I) as the benchmark, set the space between it and the discharge pipe opening (J1) as a storage bin; the shape and size of the storage bin are designed according to the discharge port (J1), and at the same time, avoid structures such as internal corners, internal right angles, external corners, and external right angles around the discharge port that may hinder the smooth flushing of excrement; the water spray direction of the flushing hole (D2) directly aligns with the discharge port (J1) along the inclined plane, adopting a siphon flushing method; coupled with the spiral flushing of the flushing hole (D1), it can strongly flush the excrement accumulated at the discharge port (J1), ensuring that the excrement and sewage are flushed clean at one time, completely removed without any residue, fundamentally preventing the occurrence of sewage backflow and blockage phenomena, ensuring the normal use function of the toilet, reducing the number of repairs and costs due to blockage, and improving the reliability and durability of the toilet.

[0051] Flushing force adjustment for efficient flushing: When flushing with medium water volume (C2) or large water volume (C3), in order to ensure the efficiency and effect of flushing, reasonably adjust the water spray volume of the D1 water spray nozzle by changing the pipe diameter of the water supply pipe of the upper flushing hole (D1); through accurate experimental data verification and actual use experience accumulation, design that the water spray volume of the D1 water spray nozzle each time accounts for 25% of the total water volume; thus, the lower flushing hole (D2) can obtain sufficient water volume and water pressure, generating a strong flushing force, so as to be able to flush the excrement in the storage bin clean at one time, avoiding problems such as multiple flushes or incomplete flushing due to insufficient flushing force, saving water resources, ensuring the cleanliness of the toilet interior, and improving users' satisfaction and usage experience with the toilet.
