[0001] This utility model relates to the field of toilet technology, specifically to a toilet seat capable of flushing the toilet bowl, an upper mechanism for a composting toilet, and a composting toilet. Background Technology

[0002] Composting toilets, also known as biodegradable toilets, are a new type of toilet that has emerged in recent years. They can degrade human waste through microorganisms, making them particularly suitable for indoor environments such as RVs, yachts, and nursing homes for elderly people with limited mobility, where it is inconvenient to connect water or discharge sewage.

[0003] Currently, due to structural design limitations, existing composting toilets cannot be flushed directly or by siphon like ordinary household toilets. They can only be flushed using the spray nozzles or shower heads provided in the toilet, which is inconvenient to use.

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

[0005] In view of this, the present invention provides a toilet seat capable of flushing the toilet bowl, a composting toilet upper mechanism, and a composting toilet.

[0006] The technical solution is as follows:

[0007] The first aspect of this application relates to a toilet seat capable of flushing a toilet bowl, comprising a seat body, wherein the inner surface of the seat body is provided with a water spraying and flushing structure capable of spraying water outward.

[0008] The toilet seat with the above-mentioned flushing mechanism can spray water outwards, thus cleaning the toilet bowl by spraying water.

[0009] In some embodiments, the water spray flushing structure includes a spray arm rotatably mounted on the inner surface of the cover body and a flushing water supply structure for supplying water to the spray arm inlet of the spray arm.

[0010] In some embodiments, the spray arm includes a spray arm mounting base and at least one spray arm distributed circumferentially on the spray arm mounting base. The flushing water supply structure includes a spray arm base disposed on the inner surface of the cover plate body. The spray arm base has a base cavity.

[0028] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0029] Example 1:

[0030] like Figures 1-5 As shown, a toilet seat capable of flushing the toilet bowl mainly includes a seat body 1, the main structure of which is similar to that of a regular toilet seat. The special feature of this embodiment is that the inner surface of the seat body 1 is provided with a water spraying and flushing structure capable of spraying water outwards.

[0031] By setting a water spray flushing structure, the toilet seat in this embodiment can spray water outward through the water spray flushing structure, thereby enabling the toilet seat to clean the toilet bowl by spraying water. For details, please refer to Embodiment 2.

[0032] Furthermore, the water spray flushing structure in this embodiment preferably consists of a spray arm 2 and a flushing water supply structure 3 for supplying water to the spray arm inlet 2a of the spray arm 2. The spray arm 2 is rotatably mounted on the inner surface of the cover body 1, and its structure is similar to the spray arm of a dishwasher and the nozzle structure of a rotating water sprayer for landscaping. When the flushing water supply structure 3 supplies water to the spray arm 2, the spray arm 2 automatically rotates continuously in a set direction while spraying water, achieving a large-area three-dimensional water spray coverage, thus achieving a highly efficient flushing function for the toilet bowl. It not only flushes very cleanly but also has extremely high flushing efficiency and is very water-saving.

[0033] It should be noted that the water spray flushing structure can also have multiple small water outlet holes opened on the inner surface of the toilet seat body 1, and the flushing water supply structure 3 supplies water to each small water outlet hole, which can also realize the function of the toilet seat cleaning the toilet bowl by spraying water.

[0034] In this embodiment, the spray arm 2 includes a spray arm mounting base 2b and at least one spray arm 2c distributed circumferentially on the spray arm mounting base 2b. That is, one or more spray arms 2c can be provided. When multiple spray arms 2c are provided, each spray arm 2c is preferably evenly distributed circumferentially on the spray arm mounting base 2b, so that the spray arm 2 can rotate more smoothly.

[0035] Meanwhile, the flushing water supply structure 3 includes a spray arm base 3b disposed on the inner surface of the cover plate body 1. The spray arm base 3b has a base cavity 3b1. The spray arm mounting seat 2b is rotatably mounted on the spray arm base 3b, and the spray arm inlet 2a is opened on the spray arm mounting seat 2b. Moreover, the spray arm mounting seat 2b communicates with the base cavity 3b1. This ensures both reliable installation of the spray arm 2 and stable water supply.

[0036] Correspondingly, each spray arm 2c is provided with an inner cavity 2c3 that communicates with the spray arm inlet 2a, and each spray arm 2c has a number of flushing nozzles 2c1 that communicate with the inner cavity 2c3 on the side surface away from the cover plate body 1.

[0037] Therefore, the water supplied by the flushing water supply structure 3 is supplied to the spray arm inlet 2a through the base cavity 3b1, and then the water entering the spray arm inlet 2a is supplied to the corresponding flushing spray nozzle 2c1 through the cavity 2c3 of each arm.

[0038] It should be noted that, please refer to Figure 4 For each spray arm 2c, there is at least one flushing nozzle 2c1 used to rotate the spray arm 2c while also performing the flushing function. When the toilet seat is closed, the water spraying direction of the flushing nozzle 2c1 is set diagonally downward in the opposite direction to the rotation direction of the spray arm 2c. The water spraying directions of the other flushing nozzles 2c1 are set in different directions to improve the coverage and flushing effect.

[0039] Furthermore, the flushing nozzle 2c1, which is used to rotate the spray arm 2c while also serving the flushing function, is usually located at the outermost end of the corresponding spray arm 2c, thereby improving the rotation capability of the spray arm 2.

[0040] Because the water sprayed from each flushing nozzle 2c1 is highly likely to splash back onto the surface of the toilet bowl being flushed, the inner surface of the toilet seat body 1 may become contaminated. Therefore, please refer to... Figure 5 In this embodiment, the spray arm 2c is provided with a plurality of self-cleaning spray nozzles 2c2 that communicate with the inner cavity 2c3 of the arm on one side surface near the cover body 1. The spray direction of each cleaning spray nozzle 2c2 is towards the cover body 1, so that the inner surface of the cover body 1 can be rinsed at the same time, realizing the self-cleaning function of the cover body 1 and improving the user experience.

[0041] Please see Figures 1-3 The flushing water supply structure 3 in this embodiment also includes a water channel 3a integrally formed in the cover body 1. The water outlet 3a1 of the water channel 3a is connected to the spray arm base 3b, and the water inlet 3a2 of the water channel 3a is opened on the surface of the cover body 1. This design improves the integrity and aesthetics of the toilet seat.

[0042] It should be noted that the flushing water supply structure 3 can also be a water pipe installed on the cover plate body 1. The water outlet of the water pipe is connected to the spray arm base 3b. This design reduces the manufacturing difficulty of the cover plate body 1, thereby reducing the overall manufacturing cost.

[0043] Example 2:

[0044] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 A composting toilet upper mechanism includes a toilet bowl 5 and a toilet seat as described in Embodiment 1. The seat body 1 is installed on top of the toilet bowl 5 in an openable or closed manner. Typically, the rear end of the seat body 1 is installed on top of the toilet bowl 5 by a hinge, which is simple and reliable.

[0045] The toilet bowl 5 has a recessed toilet bowl 5a at its top. When the toilet seat 1 is closed on the toilet bowl 5, the water spray flushing structure is located above the toilet bowl 5a, thus enabling the toilet bowl 5a to be flushed. Therefore, when the toilet seat is closed, the toilet bowl 5a can be directly flushed by the water spray flushing structure, which not only cleans the toilet bowl 5a but also eliminates the need for users of composting toilets to use external devices (such as toilet nozzles or shower heads) to flush the toilet bowl 5a. This simplifies operation and significantly improves the convenience of using composting toilets.

[0046] When the water spray flushing structure directly flushes the toilet bowl 5a, the gap between the inner surface of the toilet seat body 1 and the inlet of the toilet bowl 5a may cause water overflow and contaminate the seat ring. Therefore, please refer to... Figure 1A water-blocking structure 4 is provided on the inner surface of the cover body 1, which surrounds the water spray flushing structure. The water-blocking structure 4 is adapted to the inlet of the toilet bowl 5a. When the cover body 1 is closed on the toilet bowl 5, the water-blocking structure 4 blocks the circumferential gap between the inlet of the toilet bowl 5a and the cover body 1, thereby avoiding the problem of contamination of the seat ring and water overflow.

[0047] Furthermore, the water-blocking structure 4 can be integrally molded onto the cover plate body 1, ensuring the connection strength between the water-blocking structure 4 and the cover plate body 1, and preventing the problem of detachment.

[0048] Furthermore, the water-blocking structure 4 is preferably made of flexible plastic material and the cover plate body 1 made of rigid plastic material is integrally molded through a two-color injection molding process, thereby improving the sealing performance of the water-blocking structure 4.

[0049] It should be noted that the water-blocking structure 4 can also be connected to the cover plate body 1 by a fixed installation method, which reduces the manufacturing difficulty and production cost of the cover plate body 1.

[0050] Example 3:

[0051] A composting toilet includes a toilet base and a composting toilet upper mechanism as described in Embodiment 2, with a toilet bowl 5 mounted on top of the toilet base. Most importantly, please see... Figure 2 , Figure 6 and Figure 7 The toilet bowl 5 is equipped with a toilet bowl water tank 6 and a toilet bowl water pump 7. The toilet bowl water tank 6 is connected to the inlet of the toilet bowl water pump 7 via a pipe, and the outlet of the toilet bowl water pump 7 is connected to the flushing water supply structure 3 via a pipe. This design makes efficient use of the internal space of the toilet bowl 5, resulting in a high degree of integration. At the same time, it does not occupy the internal space of the toilet base, allowing for the installation of a larger composting tank and urine tank in the toilet base, thus extending the cleaning cycle of the composting toilet.

[0052] Furthermore, the toilet bowl water tank 6 is preferably arranged around the toilet bowl 5a in an integral manner with the toilet bowl 5, making reasonable use of the space around the toilet bowl 5a, thereby making the overall structure of the composting toilet extremely compact.

[0053] Please see Figure 6 The upper part of the toilet bowl 5 is provided with a water inlet 6a for adding water to the toilet bowl water tank 6. The water inlet 6a is usually sealed with a plug, making it convenient to use.

[0054] Furthermore, a drain valve 6b is provided at the bottom of the toilet bowl 5 for emptying the toilet bowl water tank 6, so that the toilet bowl water tank 6 can be completely emptied when the toilet is not used for a long time, avoiding the growth of bacteria, improving the convenience of use, and making the toilet safe and hygienic.

[0055] Example 4:

[0056] A composting toilet, the basic structure of which is roughly the same as that of embodiment 3, the difference being that: the toilet bowl 5 does not have a toilet bowl clean water tank 6 and a toilet bowl water pump 7, but a toilet bowl clean water tank and a toilet water pump are provided on the toilet base. The toilet bowl clean water tank is connected to the water inlet of the toilet water pump through a pipe, and the water outlet of the toilet water pump is connected to the flushing water supply structure 3 through a pipe. This design reduces the manufacturing difficulty of the toilet bowl 5.

[0057] 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.
