Biodegradable toilet bowls, toilet dry and wet separation mechanisms, and biodegradable toilets

Abstract

This utility model discloses a biodegradable toilet bowl, a toilet dry and wet separation mechanism, and a biodegradable toilet. The toilet bowl is divided into a urine collection trough and a fecal collection trough from front to back. The traditional bowl-shaped urine collection trough is improved into a sloping urine collection trough with its height gradually increasing away from the fecal collection trough. This significantly reduces the height of the rear anti-overflow structure compared to the traditional partition, ensuring that female urine is no longer blocked and preventing the rear anti-overflow structure from rubbing against male genitals. Simultaneously, the rear urination outlet is positioned at the lowest point on the side of the rear anti-overflow structure closest to the urination guide surface. Since this position is at the lowest point of the entire urine collection trough, efficient and thorough urination is ensured, preventing urine from flowing into the fecal collection trough. Furthermore, the toilet bowl depth can be designed to be shallower, increasing the height of the urine tank and biodegradation tank below, thus extending the cleaning cycle of the biodegradable toilet.

Description

Technical Field

[0001] This utility model relates to the field of toilet technology, specifically to a biodegradable toilet bowl, a toilet dry and wet separation mechanism, and a biodegradable toilet. Background Technology

[0002] Please see Figure 1 Existing biodegradable toilets typically have a commode bowl divided into a urine collection trough 111 and a feces collection trough, arranged sequentially from front to back, by a partition 113 that is either high or positioned high. For example... Figure 1 In some biodegradable toilets, the urine collection trough 111 is designed as a bowl-shaped structure, with the lowest point being the center (or nearby) of the bowl's bottom. The urine outlet 111d is also located at this point, thus requiring a relatively tall partition 113. In other biodegradable toilets, the urine collection trough is designed as a sloping structure, with the urine outlet at the frontmost low point. While this eliminates the need for a tall partition, the partition itself is located at the rear of the urine collection trough, resulting in an overall effect of a tall partition at a relatively high point.

[0003] Therefore, because women urinate further back, higher partitions (including those that are inherently high or positioned high) can obstruct urine flow, potentially causing a large amount of urine to flow into the discharge port 112a of the collection tank 112, which could lead to excessive humidity in the biodegradable container. Furthermore, higher partitions could also rub against male genitalia, causing hygiene problems and a poor user experience.

[0004] Solving these problems is now a top priority. Utility Model Content

[0005] In view of this, the present invention provides a biodegradable toilet bowl, a toilet dry and wet separation mechanism, and a biodegradable toilet.

[0006] The technical solution is as follows:

[0007] The first aspect of this application relates to a biodegradable toilet bowl, comprising a bowl body with a recessed toilet bowl at the top, the toilet bowl being divided into a urine collection trough and a feces collection trough from front to back, the feces collection trough having a discharge port, the urine collection trough being composed of a urine-guiding surface and a rear anti-overflow structure separating the urine-guiding surface and the feces collection trough, the urine-guiding surface being a sloping structure with a gradually increasing height in the direction away from the rear anti-overflow structure, the rear anti-overflow structure protruding upward at the position where it connects with the urine-guiding surface, and a rear-mounted urination port being provided around the lowest point on the side of the rear anti-overflow structure near the urine-guiding surface.

[0008] This biodegradable toilet bowl utilizes a modified urine collection trough with a gradually increasing height (higher at the front, lower at the back) that slopes away from the fecal collection trough. This significantly reduces the height of the rear anti-overflow structure compared to traditional partitions, placing it at a lower position within the bowl. This not only ensures unobstructed urine collection but also prevents the rear anti-overflow structure from rubbing against male genitalia, resolving hygiene and user experience issues. Furthermore, the rear urination outlet is positioned at the lowest point of the rear anti-overflow structure, near the urination guide surface. This location at the lowest point of the entire urine collection trough guarantees efficient and thorough urination, preventing urine from flowing into the fecal collection trough. Additionally, the bowl depth can be designed to be shallower, achieving an ultra-thin design. This allows for increased height of the lower urine tank and biodegradation tank, extending the cleaning cycle of the biodegradable toilet and improving the user experience.

[0009] In some embodiments, the rear overflow prevention structure is a strip-shaped gently sloping structure, the height of which gradually increases from the side edge near the catheter surface toward the side edge near the fecal collection trough.

[0010] In some embodiments, the length of the urine collection trough in the front-to-back direction is greater than the length of the feces collection trough in the front-to-back direction.

[0011] In some embodiments, at least one front anti-overflow structure with a shape adapted to the rear anti-overflow structure protrudes between the large surface of the catheter and the rear anti-overflow structure. Each front anti-overflow structure is arranged sequentially in the direction away from the rear anti-overflow structure, and a front urination port is opened around the lowest point on the side of each front anti-overflow structure away from the rear anti-overflow structure.

[0012] In some embodiments, the front overflow prevention structure is composed of a fast flow guiding surface on the side close to the rear overflow prevention structure and a blocking and slowing surface on the side away from the rear overflow prevention structure, forming an arc-shaped triangular prism structure.

[0013] In the same front-mounted anti-overflow structure: the heights of the fast-flow guiding surface and the blocking and slow-flowing surface gradually increase from the mutually distant side edges to the mutually close side edges, and the slope of the fast-flow guiding surface is greater than the slope of the blocking and slow-flowing surface.

[0014] In some embodiments, the rear urination port is located in the middle of the rear anti-overflow structure, which is an arc-shaped strip structure that bends backward at both ends, and the height of the rear anti-overflow structure gradually increases from the middle to both ends.

[0015] Each pre-emptive urination port is located in the middle of the corresponding flow-blocking surface. Each flow-blocking surface is an arc-shaped strip structure that curves backward at both ends, and the height of each flow-blocking surface gradually increases from the middle to both ends.

[0016] The second aspect of this application relates to a toilet wet and dry separation mechanism, wherein the toilet body is provided with a urine transfer tank fixedly installed directly below the urine collection tank, a wet and dry separation baffle movably installed on the urine transfer tank, and a baffle control mechanism for controlling the wet and dry separation baffle. A urine outlet is provided at the lowest point of the bottom of the urine transfer tank. The wet and dry separation baffle can switch back and forth between a first state of blocking the outlet and a second state of not blocking the outlet under the control of the baffle control mechanism.

[0017] When the wet and dry separation baffle is in the first state, the wet and dry separation baffle extends obliquely downward to the top of the urine transfer tank, and a drainage gap is formed between the wet and dry separation baffle and the discharge port, so that the liquid collected by the wet and dry separation baffle can flow to the urine transfer tank.

[0018] The above-mentioned toilet wet and dry separation mechanism not only possesses all the advantages of biodegradable toilet bowls, but also allows users to keep the wet and dry separation baffle in its first state during urination. Due to the baffle's inclined design and drainage gap, any small amount of urine leaking into the drain outlet can be collected by the baffle and guided to the urine transfer tank, where it is ultimately collected completely. This avoids the problem of excessive humidity in the biodegradable container affecting biodegradation efficiency.

[0019] In some embodiments, the baffle control mechanism includes a push-pull slide extending in the front-rear direction, the bottom of the urine transfer tank is provided with a plurality of slide seats adapted to the push-pull slide, the push-pull slide is slidably mounted on each slide seat, the rear end of the push-pull slide is fixedly connected to the rear end of the dry and wet separation baffle through a baffle connector, and the front end of the push-pull slide is provided with a gripping structure.

[0020] In some embodiments, the baffle control mechanism includes a push-pull rod that extends in the left-right direction and is fixedly installed at the rear end of the wet and dry separation baffle, and a drive rod that is rotatably installed on the toilet body. At least one end of the push-pull rod is connected to the drive rod via a crank-connecting rod mechanism, and one end of the drive rod is provided with a rotation operation structure.

[0021] The third aspect of this application relates to a biodegradable toilet, including the aforementioned toilet wet and dry separation mechanism.

[0022] The above-mentioned biodegradable toilets possess all the advantages of a toilet with a wet and dry separation mechanism. Attached Figure Description

[0033] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0034] Example 1 of biodegradable toilet bowl:

[0035] like Figure 2 As shown, a biodegradable toilet bowl mainly includes a toilet bowl body 1, the top of which has a recessed toilet bowl 11.

[0036] In this embodiment, the toilet bowl 11 can be detachably installed on the toilet body 1, allowing the toilet body 1 to be made of conventional plastic material, while the toilet bowl 11 can be made of a more easily cleanable material such as ceramic. Alternatively, the toilet bowl 11 can be integrally molded with the toilet body 1, which not only reduces cost but also minimizes the likelihood of abnormal noises due to vibration.

[0037] In this embodiment, the toilet 11 is divided into a urine collection trough 111 and a feces collection trough 112 from front to back. The feces collection trough 112 is provided with a discharge port 112a. Typically, the feces collection trough 112 is a concave curved surface structure, and the discharge port 112a is located around the lowest point of the feces collection trough 112.

[0038] The urine collection tank 111 consists of a large urine-conducting surface 111a and a rear anti-overflow structure 111b separating the large urine-conducting surface 111a and the fecal collection tank 112. The large urine-conducting surface 111a is a sloping structure with its height gradually increasing in the direction away from the rear anti-overflow structure 111b, thereby enabling the collected urine to converge towards the rear anti-overflow structure 111b. Specifically, the sloping large urine-conducting surface 111a can be a curved surface or an inclined surface, as long as it can ensure efficient drainage. In this embodiment, the large urine-conducting surface 111a preferably adopts a curved surface structure, which is more aesthetically pleasing. Furthermore, the rear anti-overflow structure 111b protrudes upward at the position where it connects with the large urine-conducting surface 111a, thereby preventing urine from overflowing from the urine collection tank 111 to the fecal collection tank 112. At the same time, a rear-mounted urination port 111c is provided around the lowest point on the side of the rear anti-overflow structure 111b closest to the large urine-conducting surface 111a.

[0039] Therefore, in this embodiment, the urine collection tank is improved into a sloping structure 111 with its height gradually increasing away from the fecal collection tank 112. That is, the urine collection tank 111 has a sloping structure that is higher at the front and lower at the back. This allows for the design of a rear overflow prevention structure 111b that only needs to achieve a flow obstruction effect. The height of the rear overflow prevention structure 111b is significantly reduced compared to the height of the traditional partition (including the actual height is also significantly reduced). This not only ensures that female urine is no longer blocked and can be collected more fully by the urine collection tank 111, but also prevents the rear overflow prevention structure 111b from rubbing against the male genitalia. This design solves the hygiene and user experience issues. Furthermore, the rear urination port 111c is positioned at the lowest point of the rear anti-overflow structure 111b, near the urination surface 111a. Since this position is at the lowest point of the entire urine collection tank 111, efficient and thorough urination is ensured, preventing urine from flowing into the fecal collection tank 112. Additionally, the toilet bowl 11 can be designed to be shallower, achieving an ultra-thin design. This allows for an increase in the height of the urine tank and biodegradable tank located below, extending the cleaning cycle of the biodegradable toilet and improving the user experience.

[0040] Furthermore, the rear overflow prevention structure 111b is preferably a strip-shaped gently sloping structure, the height of which gradually increases from the side edge near the urinary guide surface 111a towards the side edge near the fecal collection trough 112. Therefore, the rear overflow prevention structure 111b in this embodiment is similar to a flood control dike, serving both to impede flow and slow down the flow. This allows the rear overflow prevention structure 111b, even when designed to be very low, to achieve the same impeding effect as a taller strip or plate-shaped separating rib, preventing urine from rushing into the fecal collection trough 112, and further avoiding problems such as obstruction of female urine and rubbing against male genitalia. It should be noted that the rear overflow prevention structure 111b can also adopt common structures such as ordinary insulating ribs, as long as they can effectively prevent water from entering.

[0041] The urine collection trough 111 of existing biodegradable toilets is designed to be very short. Specifically, the length of the urine collection trough 111 in the front-to-back direction of existing biodegradable toilets is designed to be shorter than the length of the fecal collection trough 112 in the front-to-back direction. This results in poor urine collection capacity of the urine collection trough 111 and makes it very easy for urine to spill directly into the fecal collection trough 112.

[0042] To address the aforementioned issues, this embodiment designs the length of the urine collection trough 111 along the front-to-back direction to be greater than the length of the feces collection trough 112 along the front-to-back direction, thereby significantly improving the urine collection capacity of the urine collection trough 111 and greatly reducing the possibility of urine spilling into the feces collection trough 112.

[0043] Furthermore, the rear overflow prevention structure 111b is a strip-shaped inclined structure. Specifically, the rear urination port 111c is located in the middle of the rear overflow prevention structure 111b, which is an arc-shaped strip structure that curves backward at both ends, extending to the boundaries of the left and right sides of the urine collection tank 111. The height of the rear overflow prevention structure 111b gradually increases from the middle to both ends. This design not only ensures efficient urine collection but also further enhances the blocking and overflow prevention effect of the rear overflow prevention structure 111b. Simultaneously, it is easy to manufacture and aesthetically pleasing.

[0044] Furthermore, the catheter surface 111a has a curved structure, which is not only smooth, aesthetically pleasing, and easy to rinse, but also allows urine on it to be quickly and completely guided to the rear urination port 111c, thus preventing the accumulation of dirt on the surface and improving the user experience.

[0045] Furthermore, the rear urination port 111c can be a waist-shaped hole extending in the left-right direction, enabling rapid urination and waste removal. The rear urination port 111c can also consist of multiple small holes, providing a certain filtering effect and preventing larger foreign objects from leaking in. The rear urination port 111c can also include a waist-shaped hole extending in the left-right direction and small holes distributed around the waist-shaped hole, further improving the speed of urination and waste removal.

[0046] Example 2 of biodegradable toilet bowl:

[0047] Please see Figure 3 The structure of this embodiment is basically the same as that of the biodegradable toilet bowl embodiment 1. The difference is that a front anti-overflow structure 113 with a shape that is adapted to the rear anti-overflow structure 111b is formed between the urinary catheter surface 111a and the rear anti-overflow structure 111b. A front urination port 114 is provided around the lowest point on the side of the front anti-overflow structure 113 away from the rear anti-overflow structure 111b.

[0048] By adding a front anti-overflow structure 113 and a front urination port 114, the risk of overflow problems in the rear anti-overflow structure 111b can be reduced, while retaining a large area of ​​catheterization surface 111a, which is not only aesthetically pleasing but also less prone to scale buildup.

[0049] Furthermore, each of the front overflow prevention structures 113 is composed of a rapid flow guiding surface 113a on the side closer to the rear overflow prevention structure 111b and a blocking and slowing surface 113b on the side farther from the rear overflow prevention structure 111b, forming an arc-shaped triangular prism structure. Specifically, in the same front overflow prevention structure 113, the heights of both the rapid flow guiding surface 113a and the blocking and slowing surface 113b gradually increase from the mutually distant side edges to the mutually close side edges, and the slope of the rapid flow guiding surface 113a is greater than the slope of the blocking and slowing surface 113b. This allows the flow-blocking surface 113b, in conjunction with the front urination port 114, to achieve the same effect as the rear anti-overflow structure 111b in conjunction with the rear urination port 111c. Furthermore, due to the steep slope of the flow-blocking surface 113b, urine overflowing over it can flow rapidly to the rear urination port 111c via the rapid flow guide surface 113a. Additionally, the increased length of the flow-blocking surface 113b further enhances its blocking and anti-overflow effect. It should be noted that the front anti-overflow structure 113 can also employ common structures such as ordinary insulating ribs, as long as they effectively prevent water leakage.

[0050] In this embodiment, the flow-blocking surface 113b is a strip-shaped inclined structure. Specifically, the pre-drainage port 114 is located in the middle of the flow-blocking surface 113b, which is an arc-shaped strip structure that curves backward at both ends, extending to the boundaries of the left and right sides of the urine collection tank 111. Furthermore, the height of the flow-blocking surface 113b gradually increases from the middle to both ends. This design not only ensures the high efficiency of urine collection but also further enhances the effect of the flow-blocking surface 113b in blocking urine and preventing spillage. Simultaneously, it is easy to manufacture and aesthetically pleasing.

[0051] Furthermore, the pre-flush port 114 can be a waist-shaped hole extending in the left-right direction, enabling rapid urination and waste removal. The pre-flush port 114 can also be composed of multiple small holes, providing a certain filtering effect and preventing larger foreign objects from leaking in. The pre-flush port 114 can also include a waist-shaped hole extending in the left-right direction and small holes distributed around the waist-shaped hole, further improving the speed of urination and waste removal.

[0052] Example 3 of biodegradable toilet bowl:

[0053] Please see Figure 4The structure of this embodiment is basically the same as that of the biodegradable toilet bowl embodiment 2, except that: the urine-conducting surface 111a is almost completely covered with front anti-overflow structures 113, and each front anti-overflow structure 113 is arranged sequentially in the direction away from the rear anti-overflow structure 111b. A front urination port 114 is provided around the lowest point on the side of each front anti-overflow structure 113 away from the rear anti-overflow structure 111b. Each front anti-overflow structure 113 and each front urination port 114 is basically the same as the structure in the biodegradable toilet bowl embodiment 2. This design completely avoids the problem of urine overflowing from the urine collection tank 111 into the feces collection tank 112.

[0054] Example 1 of a toilet wet and dry separation mechanism:

[0055] Please see Figure 5 , Figure 7 and Figure 8 A toilet wet and dry separation mechanism includes a biodegradable toilet bowl embodiment 1, biodegradable toilet bowl embodiment 2, or biodegradable toilet bowl embodiment 3. The toilet bowl body 1 is provided with a urine transfer tank 12, a wet and dry separation baffle 2, and a baffle control mechanism 3.

[0056] The urine transfer trough 12 is fixedly installed on the toilet bowl body 1 and located directly below the urine collection trough 111. A urine outlet 121 is provided at the lowest point of the bottom of the urine transfer trough 12. It should be noted that the urine transfer trough 12 can be located directly below the toilet bowl 11. Furthermore, the urine transfer trough 12 has a passageway directly below the discharge outlet 112a to avoid obstructing the discharge outlet 112a. A wet / dry separation baffle 2 is movably installed on the urine transfer trough 12. Specifically, the wet / dry separation baffle 2 has two states: a first state that obstructs the discharge outlet 112a and a second state that does not obstruct the discharge outlet 112a. A baffle control mechanism 3 is used to control the wet / dry separation baffle 2 to switch back and forth between the first and second states.

[0057] Therefore, please see Figure 7 When a user needs to urinate, the baffle control mechanism 3 controls the wet and dry separation baffle 2 to be in its first state. This baffle 2 extends obliquely downwards above the urine transfer tank 12, and a drainage gap 4 is formed between the baffle 2 and the discharge port 112a, allowing the liquid collected by the baffle 2 to flow into the urine transfer tank 12. Therefore, a small amount of urine leaking into the discharge port 112a can be collected by the baffle 2 and, guided by the baffle 2, directed entirely into the urine transfer tank 12, and finally completely collected by the urine tank through the urine outlet 121. This avoids the problem of excessive humidity in the biodegradable container affecting biodegradation efficiency. Please refer to... Figure 8When a user needs to defecate, the baffle control mechanism 3 controls the wet and dry separation baffle 2 to be in the second state. At this time, the wet and dry separation baffle 2 will not block the discharge port 112a at all, and the discharge port 112a is connected to the biodegradable container.

[0058] Furthermore, in order to improve the urine collection capacity of the wet and dry separation baffle 2 and ensure its own installation stability and reliability, a collection groove 21 is formed in the middle of the wet and dry separation baffle 2. The collection groove 21 extends forward to the front end face of the wet and dry separation baffle 2. Therefore, the wet and dry separation baffle 2 has a better urine collection capacity and the ability to guide urine to the urine transfer tank 12. At the same time, since the collection groove 21 does not extend to the left and right outer edges and the rear end of the wet and dry separation baffle 2, the installation stability and reliability of the wet and dry separation baffle 2 are ensured, and abnormal noise is avoided.

[0059] In this embodiment, the wet and dry separation baffle 2 is preferably slidably mounted on the urine transfer tank 12, and the urine transfer tank 12 has a passage located directly below the discharge port 112a at its rear. When the wet and dry separation baffle 2 slides forward to its position, it does not block the passage; when the wet and dry separation baffle 2 slides backward to its position, it completely blocks the passage.

[0060] The baffle control mechanism 3 includes a push-pull slide 31 extending in the front-to-back direction. The bottom of the urine transfer tank 12 is provided with several slide seats 122 that are adapted to the push-pull slide 31. The push-pull slide 31 is slidably installed on each slide seat 122. The rear end of the push-pull slide 31 is fixedly connected to the rear end of the dry and wet separation baffle 2 through the baffle connector 32. The front end of the push-pull slide 31 is provided with a grip structure 33. The grip structure 33 is preferably a handle structure, so that the slide 31 can be easily pulled out to realize the back-and-forth position control of the dry and wet separation baffle 2. The whole structure is not only simple and reliable, but also easy to operate.

[0061] Example 2 of a toilet wet and dry separation mechanism:

[0062] Please see Figures 6-8 The structure of this embodiment is basically the same as that of the toilet dry and wet separation mechanism embodiment 1, except that the baffle control mechanism 3 is different.

[0063] Specifically, the baffle control mechanism 3 includes a push-pull rod 35 that extends in the left-right direction and is fixedly installed at the rear end of the wet and dry separation baffle 2, and a drive rod 34 that is rotatably installed on the toilet body 1. At least one end of the push-pull rod 35 is connected to the drive rod 34 through a crank-connecting rod mechanism 36. One end of the drive rod 34 is provided with a rotation operation structure. By rotating the rotation operation structure back and forth, the drive rod 34 can be driven to rotate forward or backward, thereby realizing the back-and-forth position control of the wet and dry separation baffle 2.

[0064] Biodegradable toilet Example 1:

[0065] A biodegradable toilet includes a toilet dry and wet separation mechanism, either Example 1 or Example 2.

[0066] Specifically, the toilet body 1 is installed on top of the toilet shell. A urine tank and a biodegradable tank are detachably installed in the toilet shell. Both the urine tank and the biodegradable tank are located below the toilet body 1. The inlet of the urine tank is connected to the urine outlet 121. Typically, the urine outlet 121 can be connected to the inlet of the urine tank through a pipe, or the inlet of the urine tank can be located directly below the urine outlet 121. Similarly, the inlet of the biodegradable tank is located directly below the discharge port 112a.

[0067] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
