Description

Technical Field

[0001] The invention relates to the technical field of sanitary equipment, and in particular to a urinal structure and a urinal. Background Art

[0002] Urinals are a common sanitary equipment widely used in public places and homes for men to urinate. Urinals are usually fixed on the wall for easy drainage and flushing. Since the advent of urinals, their design and functions have been continuously improved to enhance the user experience and hygiene standards. As people pay more attention to public health, the design of modern urinals has gradually developed in the direction of water conservation, environmental protection and intelligence. For example, induction urinals automatically flush water through infrared sensing, avoiding manual operation and reducing the risk of contact infection.

[0003] Although urinals have made some progress in design and function, there are still some problems that need to be solved in actual use. The flushing system of traditional urinals usually relies on a fixed amount of water flow and a preset flushing path. However, due to design limitations, these flushing paths may not be effectively covered in certain areas, resulting in incomplete flushing and forming sanitary dead corners. This phenomenon not only affects the cleaning effect of the urinal, but may also cause odor, further affecting the sanitary environment of public places. Summary of the invention

[0004] In order to solve the above problems, the present application provides a urinal structure and a urinal.

[0005] In a first aspect, the present application provides a urinal structure, which adopts the following technical solution: A urinal structure, used for installation on a seat body, comprising: a slot body, used for being rotatably mounted on the seat body, the slot body comprising a front side and a back side, the front side being provided with a notch; and, A downpipe, disposed in the trough body and connected to the trough body, wherein the rotation axis of the trough body coincides with the central axis of the downpipe; Among them, the front side is a first arc surface with the central axis of the sewer pipe as the center of rotation, and the central angle of the first arc surface is less than or equal to 180 degrees.

[0009] Preferably, a shell is arranged around the tank; wherein, A deformation gap is provided between the trough body and the shell; And / or, the tank body is integrally arranged with the housing; And / or, reinforcing ribs are provided between the down pipe and the tank body; And / or, reinforcing ribs are arranged between the trough body and the shell.

[0010] Preferably, the shell includes a lower edge, which extends from the notch to near the drain pipe; the end of the lower edge close to the drain pipe is the lower end, and the lower edge is used to guide the liquid overflowing from the notch to flow along the shell surface to the lower end.

[0011] Preferably, the trough body is made of plastic, and the downpipe is integrally formed with the trough body; The down pipe comprises a limiting portion, and the limiting portion is a structure protruding from and / or recessed in the outer surface of the down pipe.

[0012] Preferably, the down pipe comprises an enlarged section and a connecting section, the enlarged section is connected to the trough body, the connecting section is connected to the enlarged section, and the inner diameter of the enlarged section is larger than the inner diameter of the connecting section.

[0013] Preferably, the side wall of the enlarged section protrudes outward to form the limiting portion; And / or, there is a smooth transition between the inner wall of the enlarged section and the inner wall of the connecting section.

[0014] In a second aspect, the present application provides a urinal, which adopts the following technical solution: A urinal, comprising the urinal structure described in the above technical solution, and further comprising a seat body, wherein the urinal structure is rotatably mounted on the seat body, and the seat body is provided with a water receiving tray, and the water receiving tray is located at the end of the trough body facing the downpipe; Along the central axis direction of the downpipe, the projection of the lower end toward the water receiving tray is located inside the water receiving tray.

[0015] The present invention has the following advantages and beneficial effects: The present application enables the tank to rotate relative to the base by rotatably mounting the tank on the base. When the inside of the tank needs to be cleaned, the slot can be rotated to the side away from the user to achieve a more comprehensive cleaning effect.

[0017] Furthermore, the rotation axis of the trough body coincides with the central axis of the downpipe. This structural design not only makes the trough body drain more smoothly during rotation, but also optimizes the compactness of the overall structure. Through this design, the rotation of the trough body will not affect the function of the downpipe, while reducing the installation space requirements, making installation easier and effectively saving space.

[0021] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0023] Combine the following Figures 1 to 14 A urinal structure and a urinal provided in the embodiment of the present application are described in detail through specific embodiments and application scenarios.

[0024] A first aspect of this embodiment describes a urinal structure in detail.

[0025] Reference Fig.11 , Fig.14 The embodiment of the present application provides a urinal structure for installation on a seat 11. The seat 11 provides an installation base for the urinal structure. As an example, the seat 11 can be fixed on a wall or other supporting components. For example, when the seat 11 is fixed on the wall, the urinal structure is fixed on the wall through the seat 11 for use by the user.

[0026] Reference Figure 1 , Figure 2 The urinal structure includes a trough body 100 and a downpipe 200. The trough body 100 is rotatably mounted on the seat body 11, and includes a front side 160 and a back side 170. Preferably, the trough body 100 can be controlled to rotate at a preset angle to achieve the front side 160 and the back side 170 being in a working position (the working position is the position facing the user), and the preset angle is 90°~270°. In this embodiment, the trough body 100 is set to rotate 180° to achieve the front side 160 and the back side 170 being alternately in the working position. The front side 160 is provided with a notch 110 for receiving urine, wherein the front side 160 is the side that the user faces when urinating. When the front side 160 of the urinal faces the user, the user can use it normally; while the back side 170 does not have the urination function.

[0027] Reference Figure 2 , Figure 3 In some embodiments, the downpipe 200 is fixedly connected to the trough body 100 and communicated with the notch 110. When the user urinates, urine enters the trough body 100 through the notch 110 and further flows into the downpipe 200. With this structural design, the rotation axis of the trough body 100 is configured to coincide with the central axis of the downpipe 200. Therefore, when the trough body 100 rotates relative to the seat body 11, the relative position of the downpipe 200 remains unchanged, which to a certain extent helps the downpipe 200 to drain water smoothly in various situations.

[0028] The effect of this design is mainly reflected in that no matter what rotation position the tank body 100 is in, the downpipe 200 can maintain the stability of its drainage function. Because the position of the downpipe 200 does not change with the rotation of the tank body 100, the poor drainage caused by the change of relative position is avoided. In addition, this structure can also reduce system failures caused by poor drainage and improve reliability during use.

[0029] It should be further explained here that the rotation axis of the tank body 100 coincides with the central axis of the downpipe 200, which means that the downpipe 200 always remains in a fixed position on the seat body 11 during the rotation of the tank body 100, avoiding drainage obstacles caused by changes in relative positions. This is beneficial for the downpipe 200 to be able to effectively drain water in different usage states.

[0030] In some embodiments, reference Fig.11 , Fig.12 The seat body 11 has an installation cavity and an opening, and the tank body 100 is movably installed in the installation cavity to switch between a first state and a second state. Parts such as a nozzle will be installed in the installation cavity, and the part of the tank body 100 in the installation cavity can be cleaned by the nozzle. The installation cavity is used to accommodate the tank body 100, and the opening connects the installation cavity with the outside world. During use, it is necessary to pre-set a cavity for installing the installation shell 300 on the wall or the support body, and fix the installation shell 300 in the cavity to ensure that the opening is located outside the cavity. Through this design, when the tank body 100 is active, its front 160 or back 170 can be located on the opening side respectively.

[0031] Reference Fig.11 When the tank body 100 is in the first state, the front side 160 of the tank body 100 is located at the opening side, and the back side 170 is located in the installation cavity. Fig.12 , while when the tank body 100 is in the second state, the back side 170 of the tank body 100 is located on the opening side, and the front side 160 is located in the installation cavity. When the front side 160 is located on the opening side, the tank body 100 can be used for urination by the user. It can be understood that when the tank body 100 is in the second state, the cleaning devices such as the nozzle in the installation cavity can clean various areas of the front side 160 of the tank body 100, and the various areas of the front side 160 of the tank body 100 include the interior of the tank body 100 and the outer shell part of the front side 160. In addition, when the tank body 100 is in the first state, the cleaning devices such as the nozzle in the installation cavity can also clean the back side 170. Whether to clean the back side 170 needs to be set according to actual needs.

[0032] In some embodiments, reference Figure 4 , Figure 5 , the front side 160 is the first curved surface 130 with the central axis of the water pipe 200 as the center of rotation, and the central angle of the first curved surface 130 is less than or equal to 180 degrees. The front side 160 is the first curved surface 130 with the central axis of the water pipe 200 as the center of rotation, which means that the first curved surface 130 is a part of the rotation surface with the central axis of the water pipe 200 as the center of rotation, that is, the contour shape of the front side 160 is a part of the rotation surface with the central axis of the water pipe 200 as the center. In other words, the contour of the front side 160 is a partial rotation surface.

[0033] It is understandable that when the tank body 100 is in the first state, the first curved surface 130 is partially located in the installation cavity. At this time, a cleaning device such as a spray head can clean the first curved surface 130 and the inside of the slot 110 . Since the center angle of the first arc surface 130 is controlled within 180 degrees, when the first arc surface 130 is located in the installation cavity, the cleaning device such as the nozzle can clean the entire outer wall surface (the first arc surface 130) without any cleaning dead angle, and the front side 160 is the structural feature of the first arc surface 130 with the central axis of the downpipe 200 as the rotation center, so that during the rotation of the urinal structure, the movement trajectory of the first arc surface 130 is on the same circumference. Based on this structure, it is only necessary to set the wiping piece on the circumference, so that the outer wall surface of the urinal can be wiped in the non-powered condition in conjunction with the rotation process of the urinal structure to remove the water stains remaining on the outer wall surface after cleaning. When the rotation angle of the urinal structure is 180°, the effective cleaning area of ​​the wiping piece can cover the entire front side 160, thereby improving the cleaning convenience of the urinal structure. In addition, the arc structure can also avoid the potential harm caused by sharp edges and corners during the rotation of the urinal structure, thereby improving the safety and convenience of the urinal structure.

[0034] According to an optional embodiment, the tank body 100 is made of plastic and / or metal, and the downpipe 200 is integrally formed with the tank body 100. This integrally formed design can reduce the use of connecting parts to a certain extent, reduce manufacturing costs, and improve the stability of the overall structure. In addition, since the downpipe 200 is directly integrated with the tank body 100, the potential leakage caused by the connecting parts is avoided, and the production process is simplified, and the consistency and durability of the product are improved.

[0035] This design also has the advantages of being light in weight and easy to clean and maintain. The use of plastic and / or metal materials makes the trough body 100 have good corrosion resistance and durability, and is suitable for long-term use in a humid environment. The one-piece molding of the overall structure can also improve the drainage efficiency to a certain extent, ensuring that urine can be smoothly discharged from the trough body 100 into the sewer pipe 200, further improving the use effect.

[0036] Exemplarily, the tank body 100 is made entirely of plastic material, or partly of plastic material and partly of metal material. In some embodiments, the tank body 100 can also be made entirely of metal material, such as stainless steel.

[0037] According to an alternative embodiment, referring to Figure 3 , Fig. 9, the trough body 100 is made of plastic and / or metal, and the downpipe 200 is integrally formed with the trough body 100. The downpipe 200 includes a limiting portion 210, which is a structure protruding and / or recessed from the outer surface of the downpipe 200. During the injection molding process of the trough body 100 and the downpipe 200, since the plastic often shrinks and deforms when cooling and solidifying, especially at the connection between the downpipe 200 and the trough body 100, due to the thick material, it is more likely to deform protruding toward the side of the trough body 100. This deformation may cause the connection between the downpipe 200 and the trough body 100 to no longer be the lowest point inside the notch 110, so that urine cannot be completely discharged, resulting in residual liquid in the notch 110 during subsequent use. The presence of residual liquid may cause splashing during use, affecting normal use.

[0038] In order to solve this problem, when the downpipe 200 and the tank body 100 are integrally formed, a protruding and / or recessed structure is provided on the surface of the downpipe 200 so as to form a snap connection with the forming mold. Through this snap connection and position limiting, the downpipe 200 is fixed by the mold during the forming process, and is restricted from shrinking toward the tank body 100, thereby prompting the tank body 100 to shrink toward the downpipe 200. In this way, it can be ensured that the connection between the downpipe 200 and the tank body 100 becomes the lowest point in the notch 110, ensuring that urine can be completely discharged, and avoiding the situation where residual liquid appears in the notch 110 during use.

[0039] According to an alternative embodiment, referring to Figure 3 , Fig.10 The down pipe 200 includes an enlarged section 220 and a connecting section 230, wherein the enlarged section 220 is connected to the tank body 100, and the connecting section 230 is connected to the enlarged section 220, and the inner diameter of the enlarged section 220 is greater than the inner diameter of the connecting section 230. By providing the enlarged section 220, the inner diameter of the connection between the down pipe 200 and the tank body 100 will suddenly increase. When the liquid enters the area of ​​sudden increase in inner diameter along the down pipe 200, the discharged liquid will be out of contact with the inner wall of the down pipe 200 and will only be affected by gravity, thereby accelerating the discharge of the liquid. This design can not only effectively accelerate the discharge of the liquid in the notch 110, but also generate a greater siphon force at the connection between the down pipe 200 and the tank body 100, promote rapid drainage, and reduce the risk of blockage at the connection between the down pipe 200 and the tank body 100 to a certain extent.

[0040] According to an optional embodiment, the side wall of the enlarged section 220 protrudes outward to form the limiting portion 210. Since the inner diameter of the enlarged section 220 is relatively large, it becomes easier to set the outward protruding structure, and at the same time, the structure of the downpipe 200 can be made more reasonable. This design not only improves the stability of the structure, but also ensures that the strength of each part is effectively guaranteed.

[0041] According to an optional embodiment, there is a smooth transition between the inner wall of the enlarged section 220 and the inner wall of the connecting section 230. This design ensures that the inner wall of the downpipe 200 is smoother, thereby avoiding the residue and accumulation of stains caused by the rough inner wall, and improving the cleaning performance and service life of the downpipe 200.

[0042] For example, the outer shape of the enlarged section 220 is designed to be spherical, and the shape of its internal channel is also spherical. In this way, the outer wall and the inner wall of the enlarged section 220 can maintain a relatively smooth state. In addition, it is easier to form the outwardly protruding stopper 210 during the injection molding process of the spherical enlarged section 220, thereby avoiding the molding problem caused by the difficulty of demolding when the stopper 210 has edges and corners. This design not only simplifies the manufacturing process, but also effectively improves the quality and consistency of the product.

[0043] According to an alternative embodiment, referring to Figure 3 , Fig. 9 , the trough body 100 is provided with a mounting portion 120 on the side away from the downpipe 200, and the trough body 100 is connected to the seat body 11 through the mounting portion 120, and the downpipe 200 and the seat body 11 are rotated and matched, and the downpipe 200 can move relative to the seat body 11 along the central axis direction of the downpipe 200. This means that the downpipe 200 can rotate relative to the seat body 11, and can also slide relative to the seat body 11 along its axis direction. Specifically, when the trough body 100 rotates relative to the seat body 11, the downpipe 200 can rotate accordingly, and the rotational cooperation between the two is realized. In addition, when the trough body 100 is deformed due to thermal expansion and contraction, especially when the length of the trough body 100 changes along the central axis direction of the downpipe 200, since the mounting portion 120 of the trough body 100 is fixedly connected to the seat body 11, this deformation can only be carried out on the side of the downpipe 200. At this time, the downpipe 200 will slide relative to the trough body 100 along its axis direction to maintain the stability and normal function of the structure.

[0044] It is understandable that, in use, it is necessary to drain water through the downpipe 200, so after installation, the downpipe 200 will be located on the lower end 151 side of the tank body 100, and the mounting portion 120 will be located on the upper end side of the tank body 100. In some embodiments, a motor and other components can be arranged on the seat body 11 to drive the tank body 100 to rotate. Since the mounting portion 120 is located at the upper end of the tank body 100, the motor and other components can be arranged on the seat body 11 opposite to the mounting portion 120. This design can place the live components at the upper end of the tank body 100, and water is not easy to contact these components during daily use and flushing, thereby reducing safety hazards and extending the service life of the equipment.

[0045] The trough body 100 in this embodiment is made of plastic material, which is more susceptible to thermal expansion and contraction than the traditional ceramic trough body 100, thereby causing the trough body 100 to increase or decrease in size along the central axis of the sewer pipe 200. Through the connection method described in this application, on the one hand, it is possible to overcome the problem of dimensional change caused by thermal expansion and contraction, and avoid the trough body 100 from being damaged due to excessive squeezing or stretching during thermal expansion and contraction. On the other hand, this design can also set the driving components and the like at the upper end of the trough body 100, reducing the probability of contact with water, thereby improving the safety of use and the reliability of the equipment.

[0046] According to an alternative embodiment, referring to Figure 4 , Figure 5 , the back surface 170 is the second curved surface 140, and the curvature of the second curved surface 140 is smaller than the curvature of the first curved surface 130. Through this design, when the urinal is in the first state, the front surface 160 can protrude from the opening of the seat body 11, close to the user, and convenient for use; and when the urinal is switched to the second state, the back surface 170 is embedded in the opening, so that the urinal can be better stored in the accommodating cavity of the seat body 11. This design not only effectively saves external space when the urinal is not in use, avoids occupying too much space, is conducive to optimizing the environmental layout and improving space utilization, but also can enhance the stability of the urinal in different states through the cooperation of the first curved surface 130 and the second curved surface 140.

[0047] In addition, since the first curved surface 130 is a part of the rotation surface centered on the central axis of the downpipe 200, and the curvature of the second curved surface 140 is smaller than the curvature of the first curved surface 130, this means that during the rotation of the tank body 100 relative to the seat body 11, a larger gap will be formed between the second curved surface 140 and the opening of the seat body 11. Fig.13 As shown, this gap not only provides convenience in the subsequent maintenance process, through which maintenance can be carried out, but also can reduce friction and wear during the switching process, thereby extending the service life of the urinal.

[0048] According to an alternative embodiment, referring to Figure 6 , Figure 7A water seal structure 400 is provided at the connection point between the trough body 100 and the sewer pipe 200. The water seal structure 400 is structurally used to form a liquid barrier, and by retaining a certain amount of water, it prevents the odorous gas in the sewer pipe 200 from escaping from the pipeline. This water seal structure 400 is widely used in the prior art, so it is not repeated here. The setting of the water seal structure 400, on the one hand, effectively isolates the air circulation, and on the other hand, it also plays a certain role in preventing the leakage of odor from the sewer, which is beneficial to improving the user's comfort experience during use. Specifically, the water seal structure 400 maintains a certain amount of water through the low point in the structure, and this part of the water can stay at the bottom of the water seal under the action of gravity. Since water has a higher density, it can block the gas from rising to a certain extent, thereby limiting the possibility of odor returning to the urinal through the sewer pipe 200. In this way, through physical isolation, the backflow of gas is effectively prevented and the air quality is improved.

[0049] In specific applications, although the main function of the water seal structure 400 is to prevent odor leakage, it also has a certain buffering effect, which helps to slow down the drainage speed and reduce the pressure of instantaneous water flow impact on the drainage system. This design is particularly suitable for public toilets, which can improve the safety and durability of use while maintaining the stability of the system.

[0050] In some embodiments, the tank body 100 is provided with a mounting groove 180, the downpipe 200 is connected to the bottom of the mounting groove 180, and part of the downpipe 200 extends into the mounting groove 180. The water seal structure 400 includes a cover body 410, which surrounds the part of the downpipe 200 located in the mounting groove 180, and forms a liquid seal space 420 for retaining liquid between the cover body 410 and the side wall of the mounting groove 180. The mounting groove 180 is located in the bottom area of ​​the tank body 100, and its opening faces the inside of the tank body 100. One end of the downpipe 200 is connected to the bottom surface of the mounting groove 180, and the pipe body of part of the downpipe 200 extends from the bottom surface of the mounting groove 180 to the internal space of the mounting groove 180. This structural design enables the downpipe 200 to achieve fluid communication with the tank body 100 through the mounting groove 180, and part of the downpipe 200 is enclosed in the tank body 100, forming a stable drainage path.

[0051] When the liquid flows out through the downpipe 200, part of the liquid is retained between the cover 410 and the side wall of the installation groove 180, forming a water seal to prevent the gas from flowing back into the groove body 100 through the downpipe 200. Figure 8As shown, bosses 411 are arranged at intervals along the circumferential direction on the outer surface of the cover body 410, and channels for liquid flow are formed between adjacent bosses 411. The channel ensures that the liquid passes smoothly during drainage, and at the same time, a certain amount of liquid is retained in the liquid-sealed space 420 between the cover body 410 and the side wall of the mounting groove 180 after the drainage is completed, so as to achieve the drainage function while preventing odor from entering the groove body 100 in the reverse direction through the sewer pipe 200. This design strikes a balance between drainage smoothness and preventing gas backflow. The "boss 411" refers to the protruding structure distributed along the circumferential direction on the outer surface of the cover body 410, which plays the role of forming a flow channel, and the "liquid-sealed space 420" refers to the space between the cover body 410 and the side wall of the mounting groove 180 where liquid is retained, and is mainly used to form a barrier layer through liquid to prevent gas backflow.

[0052] According to an alternative embodiment, referring to Figure 5 , Fig. 9 , a shell 300 is arranged around the tank body 100, and a deformation gap 310 is left between the tank body 100 and the shell 300. It can be understood that since the tank body 100 in this embodiment is made of plastic material, the strength is relatively low and it is easy to be deformed or damaged when subjected to external forces. Therefore, by arranging the shell 300 around the tank body 100, a protective effect can be played, reducing the damage of the tank body 100 caused by external forces.

[0053] Among them, the setting of the shell 300 makes the appearance of the urinal more regular. This design can not only optimize the overall aesthetics of the urinal, but also enhance its functionality. For example, the shape of the tank body 100 can be customized according to actual needs to adapt to different occasions and design requirements, so the shape of the tank body 100 may be varied. However, by setting a unified shell 300 structure on the outside, the appearance can be made more consistent and neat, thereby improving its coordination with the surrounding environment.

[0054] The housing 300 is designed as a regular external structure. In addition to being beautiful, it also has multiple practical functions. First, it helps to cooperate with other installation parts 120, such as installation interfaces with walls, drainage pipes and other accessories. This matching design reduces the gap between the housing 300 and other components, thereby improving the tightness of the installation to a certain extent, avoiding dust accumulation or water stains caused by excessive gaps, and making cleaning and maintenance more convenient.

[0055] Secondly, the regular shape of the shell 300 makes it easier to clean the surface of the urinal. The outer surface of the shell 300 is usually smooth and regular, which helps the cleaning tool to wipe smoothly and avoids dead corners or hard-to-reach areas caused by complex shapes during the cleaning process. This design is particularly important in public places because smaller gaps and smooth surfaces can effectively reduce dirt accumulation, thereby improving hygiene levels.

[0056] In summary, the housing 300 can maintain the uniformity and aesthetics of the urinal appearance, provide convenience during installation and cleaning, and improve its coordination and tightness with other installation parts 120. This design has a beneficial effect on improving the overall user experience.

[0057] According to an optional embodiment, the tank body 100 and the shell 300 are integrally formed. It is understandable that the shell 300 and the tank body 100 are made of the same material, and since there is a deformation gap 310 between the two, when the tank body 100 or the shell 300 is subjected to external force during use, the two can buffer each other, thereby reducing the risk of damage to the tank body 100 or the shell 300. This design not only enhances the durability of the overall structure, but also effectively improves the impact resistance of the product.

[0058] According to an optional embodiment, a reinforcing rib 500 is provided between the down pipe 200 and the tank body 100 (refer to Figure 6 , Figure 7 ). The reinforcement rib 500 is provided to enhance the structural strength of the connection between the downpipe 200 and the tank body 100, and improve the overall stability and impact resistance. This design can effectively prevent the connection from loosening or being damaged due to external force or long-term use, thereby extending the service life of the equipment and maintaining its reliability under high-intensity use.

[0059] According to an optional embodiment, a reinforcing rib 500 is provided between the tank body 100 and the housing 300 (see Figure 6 , Figure 7 ). The purpose of the reinforcement rib 500 is to further enhance the structural strength between the tank body 100 and the shell 300, and improve the overall stability and anti-deformation ability. With the support of the reinforcement rib 500, the connection between the tank body 100 and the shell 300 is more secure, which can effectively resist the deformation caused by external forces and reduce the risk of damage. At the same time, this design can also optimize the force distribution of the tank body 100 and the shell 300 to a certain extent, and improve the durability and service life of the product.

[0060] According to an alternative embodiment, referring to Figure 5 , Fig. 9The housing 300 includes a lower edge 150, which extends from the notch 110 to the position close to the downpipe 200; one end of the lower edge 150 close to the downpipe 200 is a lower end 151, and the lower edge 150 is used to guide the liquid overflowing from the notch 110 to flow along the surface of the housing 300 to the lower end 151. By providing the lower edge 150, when liquid overflows or flows out from the notch 110, the liquid can flow along the lower edge 150 under the adhesion of water and finally flow to the lower end 151. Since the lower end 151 is close to the downpipe 200, this design can effectively guide the overflowed or outflowing liquid to flow near the downpipe 200 to prevent the liquid from flowing around.

[0061] In some schemes, reference Fig.12 , Fig.14 , a water receiving tray 12 can be provided on the seat 11. In this way, when the tank body 100 rotates, the lower end 151 is always located in the water receiving tray 12, and the liquid overflowing or flowing out of the slot 110 can be collected to prevent the liquid from dripping onto the user's feet. In addition, by providing the shell 300, the urinal structure can form a double-layer structure. When the tank body 100 is broken, the liquid in the tank body 100 will be intercepted by the shell 300 and guided to the lower end 151, and then collected by the water receiving tray 12. This design effectively prevents the liquid from leaking to the external environment when the plastic tank body 100 is broken, further improving the safety and reliability of the structure.

[0062] A second aspect of this embodiment describes a urinal in detail.

[0063] Reference Fig.13 , Fig.14 A urinal includes the urinal structure in the above embodiment, and also includes a seat body 11, the urinal structure is rotatably mounted on the seat body 11, and the seat body 11 is provided with a water receiving tray 12, and the water receiving tray 12 is located at the end of the tank body 100 facing the downpipe 200. Along the central axis direction of the downpipe 200, the projection of the lower end 151 to the side of the water receiving tray 12 is located in the water receiving tray 12. Exemplarily, the water receiving tray 12 is arranged in the lower area of ​​the urinal structure, and along the vertical direction, the lower end 151 is arranged opposite to the water receiving tray 12, and the lower end 151 is located within the range of the water receiving tray 12. This design ensures that when the liquid flows along the lower edge 150, it can be effectively guided into the water receiving tray 12, avoiding the liquid from overflowing to other areas, thereby further improving the convenience and cleanliness during use.

[0064] In some embodiments, the water receiving tray 12 has a drain hole, a drain pipe is connected to the drain hole, and a water seal structure 400 is provided at the connection between the drain hole and the drain pipe (refer to Fig.14 ). The water seal structure 400 is widely used in the prior art, so it will not be described in detail here.

[0065] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
