DETAILED DESCRIPTION

[0018] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only relates to preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0019] As described above, in situations such as small-sized houses in big cities, rental houses without independent bathrooms, and areas where toilets are set up outdoors, traditional toilets are difficult to meet the needs of users. In view of this, the present invention provides a hidden flush toilet. The hidden flush toilet can be applied to a variety of different application scenarios to meet the toilet needs in situations such as small-sized houses in big cities, rental houses without independent bathrooms, and areas where toilets are set up outdoors. In addition, the hidden flush toilet adopts a hidden design, which can keep the environment clean and beautiful without affecting the overall appearance of the site.

[0020] According to one aspect of an embodiment of the present invention, a hidden flush toilet is provided. Figure 1-2 As shown, the hidden flush toilet includes: a cabinet 18, a decorative surface layer, a cushion layer 3, a feces collecting ring 4, a collecting component, a feces storage box and a water tank 10; a movable wheel 17 is arranged at the bottom of the cabinet 18; the feces collecting ring 4, the collecting component, the feces storage box and the water tank 10 are all detachably arranged in the cabinet 18, and the feces collecting ring 4 is located above the collecting component, and the collecting component is located above the feces storage box; the cushion layer 3 is arranged on the top of the cabinet 18, and an opening is arranged on the cushion layer 3, and the top of the feces collecting ring 4 passes through the opening and is flush with the top of the cushion layer 3; a defecation hole is formed on the inner side of the feces collecting ring 4; feces and urine enter the collecting component through the defecation hole; the water tank 10 is connected to the collecting component, and the water in the water tank 10 is input into the collecting component to transport the feces and urine collected in the collecting component to the feces storage box; the decorative surface layer is arranged above the cushion layer 3, and one side of the decorative surface layer is hinged to the cabinet 18.

[0021] Optionally, the upper surface of the feces collecting ring 4 and the upper surface of the cushion layer 3 can both be made of flexible materials.

[0022] In such Figure 2 As shown, when the decorative surface layer is closed, the hidden flush toilet (hereinafter referred to as the device for simplicity) is cabinet-shaped as a whole, and it cannot be seen as a toilet only from the appearance. This environmentally friendly hidden design can improve the overall aesthetics of the device. When the user has physiological excretion needs, the decorative surface layer can be opened, and the entire device can be used as a toilet. The user can sit on the cushion layer 3 to defecate. During defecation, feces and urine are collected into the collection component through the defecation hole. After the excretion is completed, the water tank 10 can be used to flush water into the collection component to transport the collected feces and urine to the feces storage box.

[0023] In the solution of this embodiment, the water in the water tank 10 can be input into the collection assembly to flush the feces and urine in the collection assembly. In some specific implementation schemes, a water pump 60 can be installed to transport the water in the water tank 10. The water pump 60 can be controlled by a controller or an independent start-stop switch. After the user has finished excreting, the water pump 60 can be started by the controller to flush the feces and urine.

[0024] The device of the above technical solution can be quickly moved to any location and can be applied to different application scenarios. Specifically, the device is not only suitable for solving the problem of conflicting toilet time between tenants with non-independent bathrooms, but also can provide family members with the opportunity to go to the toilet at the same time. It can also avoid the problem of going to the toilet at night and provide a comfortable defecation experience for people with movement disorders who need care. In addition, the device can also be used as a temporary toilet for outdoor use by adding external cover, which can be used to alleviate the problem of too many people and difficulty in going to the toilet during peak tourist seasons in scenic spots. In some scenarios, the device can be combined with a wheelchair to facilitate wheelchair passengers to go to the toilet.

[0025] When the toilet is not in use, the decorative surface layer can be covered on the cushion layer 3 so that the overall appearance of the device does not show any structure related to the toilet. This helps to improve the overall environmental friendliness, aesthetics and harmony of the device, so that when the device is set in scenes such as bedrooms and living rooms, it will not damage the overall appearance of the scene.

[0026] In this solution, the feces collecting ring 4, the collecting component, the feces storage box and the water tank 10 can all be detachably arranged in the cabinet 18. In this way, the feces collecting ring 4, the collecting component, the feces storage box and the water tank 10 can be easily disassembled, replaced and cleaned, and it is also convenient to dump the feces and urine stored in the feces storage box and to add water to the water tank 10.

[0027] In this solution, feces and urine first enter the collection component, and then water is transported to the collection component to transport the feces and urine to the feces storage box. This setting method can use the feces storage box to store feces and urine, and there is no need to dump the feces and urine after each use of the toilet. Moreover, transporting the feces and urine to the feces storage box can minimize the odor emitted by the feces and urine, thereby helping to improve the user experience.

[0028] In short, the hidden flush toilet of this solution has a simple structure, is easy to use, can be applied to a variety of different application scenarios, and has good environmental friendliness.

[0029] The decorative surface layer of the present invention may be one or more of the following: a chair surface layer 2, a table surface layer 1, a mirror surface layer, etc. Three implementation schemes of the decorative surface layer of the present invention are introduced below through three embodiments.

[0030] In some embodiments, the decorative surface layer is a desktop layer 1; one side of the desktop layer 1 is hinged on the cabinet 18; support blocks 14 are provided on both sides of the top of the cushion layer 3; the bottom of the desktop layer 1 is in contact with the top of the support block 14. In this embodiment, the decorative surface layer is a desktop layer 1. When the desktop layer 1 is covered on the cushion layer 3, the device can be used as a table, thereby improving the functionality of the device and helping to further improve the user experience. The material of the desktop layer 1 can be wood or plastic, and the present invention is not limited to this.

[0031] In some embodiments, the decorative surface layer is a chair surface layer 2, and one side of the chair surface layer 2 is hinged to the cabinet 18. In this embodiment, when the chair surface layer 2 covers the cushion layer 3, the device can be used as a chair, thereby improving the functionality of the device and helping to further improve the user experience. The chair surface layer 2 can be a flexible textile layer to improve comfort.

[0032] In some embodiments, Figure 1 As shown, the decorative surface layer includes a desktop layer 1 and a chair surface layer 2, both of which are hinged on the cabinet body 18; the desktop layer 1 is located above the chair surface layer 2; support blocks 14 are provided on both sides of the top of the cushion layer 3; grooves 87 adapted to the support blocks 14 are provided on the chair surface layer 2; the top of the support block 14 passes through the groove 87 and contacts with the bottom of the desktop layer 1.

[0033] In this embodiment, the device can be used in three ways, namely, it can be used as a table, a chair, and a toilet. Specifically, when the table top layer 1 is not opened, the device can be used as a table. After the table top layer 1 is opened, the device can be used as a chair. After the chair surface layer 2 is opened, the device can be used as a toilet.

[0034] In this embodiment, the table top layer 1 is kept level by the support block 14 disposed on the top of the cushion layer 3. This is because the seat surface layer 2 is usually made of flexible material, and it may not be able to keep the table top layer 1 level when supporting the table top (for example, when a heavy object is placed on the table top layer 1, it may be easily deformed, causing the object on the table top layer 1 to slide off). For this reason, the solution supports the table top layer 1 by providing the support block 14 to ensure that the table top layer 1 is always kept level, thereby preventing the object from sliding off.

[0035] Furthermore, the lower surface of the desktop layer 1 can be a flexible layer, and the upper surface can be a rigid layer (such as wood or plastic material), and the maximum unfolding angle of the desktop layer 1 (i.e., the angle between the desktop layer 1 and the chair surface layer 2) can be in the range of [90°, 120°]. Therefore, when the device is used as a chair, the desktop layer 1 can serve as a chair back, which helps to further improve the comfort of the user.

[0036] Furthermore, when the lower surface of the desktop layer 1 is a flexible layer and the upper surface is a rigid layer, an opening adapted to the support block 14 is provided on the flexible layer, and the top of the support block 14 passes through the groove 87 and the opening on the flexible layer to contact the bottom of the rigid layer to increase the supporting force of the desktop layer 1.

[0037] For example, referring to Figure 1 , 3 4. The hidden flush toilet also includes a fixed frame; the fixed frame is installed in the cabinet 18; the fixed frame includes a fixed base and a fixed frame 7 fixed on the front and rear sides of the fixed base; the stool storage box is detachably connected to the fixed base; the collecting assembly is arranged in the cabinet 18 through the fixed frame 7.

[0038] In such Figure 1 In the illustrated embodiment, a cabinet door 8 is provided at the front side of the cabinet 18, and a first partition 16 is provided inside the cabinet 18, and the first partition 16 can divide the internal space of the cabinet 18 into two layers, an upper layer and an lower layer. The fixed frame is placed on the first partition 16. The water tank 10 can be placed in the lower layer of the cabinet 18. In this case, the upper layer of the cabinet 18 is mainly used for collecting and storing feces. Since the feces storage box and the collection assembly are detachably arranged in the cabinet 18 through the fixed frame, when the device is maintained, the fixed frame can be pulled out as a whole, thereby simplifying the maintenance operation.

[0039] Figure 1 The solution in the embodiment adopts the method of placing the fixed frame on the first partition 16 to install the fixed frame in the cabinet 18. In embodiments not shown in the present invention, the fixed frame can also be installed in the cabinet 18 in other ways, for example, it can be fixed by means of snap-on, plug-in, threaded connection, etc., which will not be repeated.

[0040] In such Figure 1 In the embodiment shown, the width of the fixed base is adapted to the width inside the cabinet 18. Thus, the width dimension can be closely matched with the inside of the cabinet 18, thereby ensuring effective cooperation between the collection assembly and the feces collection circle 4.

[0041] In this example, the stool storage box is detachably connected to the fixed base. Figure 3 In the embodiment shown, a T-shaped slide rail 29 is provided on the fixed base, and a mounting groove 62 adapted to the T-shaped slide rail 29 is provided at the bottom of the feces storage box. Furthermore, a withdrawal hole is provided at the front side of the feces storage box. This arrangement makes it easy to withdraw the feces storage box as a whole, thereby making it easy to dump feces and urine and clean the feces storage box.

[0042] In such Figure 3In the embodiment shown, the fixed base is composed of a lower support plate 23 and an upper support plate 21. The width of the fixed base is the width of the lower support plate 23. The stool storage box is detachably mounted on the upper support plate 21. The front and rear sides of the upper support plate 21 are both provided with a fixing frame 7. A limit block 30 is provided on the upper support plate 21. When the stool storage box is installed in place, the stool storage box contacts the limit block 30.

[0043] The above solution fixes the feces storage box and the collecting assembly by means of a fixed frame, and the overall structure is simple and easy to disassemble, so that the feces storage box and the collecting assembly can be easily maintained.

[0044] For example, referring to Figure 5 , 6 The hidden flush toilet also includes an air collecting ring 34 and a purification component; the air collecting ring 34 is arranged between the feces collecting ring 4 and the collecting component; a plurality of air collecting holes 39 are arranged on the inner side of the air collecting ring 34; the purification component is connected with the air collecting holes 39; the waste gas in the collecting component enters the purification component through the air collecting holes 39, and is discharged after being purified by the purification component.

[0045] Optionally, the air collecting ring 34 may be made of a rubber material having a certain hardness.

[0046] Optionally, the gas collecting ring 34 can be designed to be hollow, and the outside of the gas collecting ring 34 can be connected to the purification component. When in use, the exhaust gas enters the gas collecting ring 34 through the gas collecting holes 39, and enters the purification component through the gas collecting ring 34.

[0047] Optionally, the purification component can adopt any existing or future developed device that can purify toilet waste gas. For example, the purification component can include an air pump and a gas filter, and the waste gas is extracted from the collection component by the air pump and discharged after being purified by the odor filter.

[0048] In such Figure 6 In the illustrated embodiment, the purification component is a purification fan 38 , and the purification fan 38 is connected to the air collecting ring 34 through a pipeline.

[0049] Furthermore, the purification fan 38 can be installed on the rear side panel in the cabinet 18. Figure 7 As shown, the rear side plate of the cabinet 18 may be provided with a gas outlet 40. The gas purified by the purification fan 38 is discharged through the gas outlet 40. It can be understood that Figure 7 Only a specific structure of the back of the cabinet 18 is shown, and thus only a portion of the structure of the back of the cabinet 18 is shown.

[0050] Further, the purification fan 38 can be controlled by a controller or an independent start-stop switch. For example, when the user starts to use the toilet, the purification fan 38 can be controlled to start running by a controller or an independent start-stop switch.

[0051] In the above technical solution, by providing the air collecting ring 34 and the purification component, the waste gas in the collection component can be purified while the user is using the toilet, thereby preventing the waste gas from polluting the environment around the device and improving the user's comfort when using the toilet.

[0052] For example, referring to Figure 4-6 8. A positioning pin 37 is provided at the bottom of the air collecting ring 34, and a buffer spring 36 is sleeved on the positioning pin 37; a positioning hole 28 adapted to the positioning pin 37 is provided at the top of the fixing frame 7; the positioning pin 37 is installed in the positioning hole 28 by insertion, and the buffer spring 36 is located between the fixing frame 7 and the air collecting ring 34.

[0053] Optionally, the positioning pin 37 and the air collecting ring 34 can be designed to be separable or integrated. For example, a hole for installing the positioning pin 37 can be set at the bottom of the air collecting ring 34, and the positioning pin 37 can be fixed to the bottom of the air collecting ring 34 by interference fit. Of course, the positioning pin 37 can also be designed to be integrated with the bottom of the air collecting ring 34.

[0054] Furthermore, in order to increase the running-in durability of the positioning pin 37 and the buffer spring 36 , the positioning pin 37 can be made of metal.

[0055] The inventor found during the research that when the user sits on the cushion layer 3, the cushion layer 3 will be deformed. At this time, if the feces collecting ring 4 does not change accordingly, the top of the feces collecting ring 4 is higher than the top of the cushion layer 3, which may cause discomfort during defecation. If the top of the feces collecting ring 4 is slightly lower than the top of the cushion layer 3, although it can solve the discomfort caused by the top of the feces collecting ring 4 being higher than the top of the cushion layer 3 when the user sits on the cushion layer 3, in this case, feces and urine may contaminate the area around the opening of the cushion layer 3. In the scheme of this example, by setting a positioning pin 37 at the bottom of the air collecting ring 34 and sleeved on the positioning pin 36, when the user sits on the cushion layer 3, the feces collecting ring 4 can press the air collecting ring 34 to move downward under the action of pressure, so that the feces collecting ring 4 can change color when the cushion layer 3 is deformed, ensuring the effective cooperation between the feces collecting ring 4 and the cushion layer 3. In this way, the comfort of the defecation process can be guaranteed, and the feces and urine can be prevented from contaminating the cushion layer 3.

[0056] For example, see Figure 5 The hidden flush toilet also includes a splash-proof curtain, which includes a positioning ring 31, the inner side of the positioning ring 31 extends downward to form a curtain body 32, and the bottom of the curtain body 32 is lower than the air collecting ring 34; the positioning ring 31 is arranged between the feces collecting ring 4 and the air collecting ring 34, and there is a gap between the curtain body 32 and the air collecting hole 39. The splash-proof curtain can be made of materials such as plastic, rubber, etc., which will not be repeated.

[0057] Optionally, the positioning ring 31, the feces collecting ring 4 and the air collecting ring 34 can be connected by any method such as threaded connection, plug-in connection, and clamping connection. Figure 5 and Fig. 9 A fixing block 35 is provided on the upper surface of the air collecting ring 34, a fixing hole 33 adapted to the fixing block 35 is provided on the positioning ring 31, and a fixing groove 42 adapted to the fixing block 35 is provided at the bottom of the feces collecting ring 4. The fixing block 35 passes through the fixing hole 33 and is inserted into the fixing groove 42 to achieve relative fixation between the positioning ring 31, the feces collecting ring 4 and the air collecting ring 34. The fixing method of this solution has a simple structure and is detachable as a whole, so that the splash curtain, the feces collecting ring 4 and the air collecting ring 34 can be easily disassembled, cleaned and replaced.

[0058] Optionally, the shape formed by the curtain body 32 can be consistent with the shape of the defecation hole.

[0059] In the above scheme, by installing the splash-proof curtain and ensuring that the bottom of the curtain body 32 is lower than the air collecting ring 34, a dual protection effect is achieved: on the one hand, it effectively prevents feces and urine from contaminating the feces collecting ring 4, and on the other hand, it prevents feces and urine from being sucked into the air collecting ring 34 when the air collecting ring 34 performs the air suction purification operation. In addition, a certain distance is maintained between the curtain body 32 and the air collecting hole 39. This design is intended to ensure that the curtain body 32 will not block the exhaust gas from smoothly entering the air collecting hole 39, thereby ensuring the normal operation of the purification component.

[0060] For example, referring to Figure 3 , 5 10. A shielding sheet 6 is provided on the inner front side of the air collecting ring 34, and the shielding sheet 6 can rotate relative to the air collecting ring 34. When the decorative surface layer is opened, the shielding sheet 6 is in a vertical state to prevent urine from overflowing during defecation; when the decorative surface layer is closed, the shielding sheet 6 rotates in a direction away from the decorative surface layer.

[0061] Optionally, the shielding sheet 6 is made of a flexible material. For example, it can be soft plastic or rubber. In this solution, considering that different users have different rotation states between their legs when defecating, for some users with a smaller angle between their legs when defecating, their legs may contact the shielding sheet 6 when they sit on the cushion layer 3. In this solution, by setting the shielding sheet 6 to be a flexible material, when the user sits on the cushion layer 3 to defecate, the shielding sheet 6 can be appropriately deformed under the force of the user's legs, thereby minimizing the impact on the user's comfort while playing a shielding role.

[0062] The shielding sheet 6 can be rotated manually by the user or automatically. Fig.10As shown, a rotating shaft 43 is arranged between the shielding sheet 6 and the air collecting ring 34, and both ends of the rotating shaft 43 are fixed on the air collecting ring 34. The shielding sheet 6 is connected to the rotating shaft 43 and can rotate relative to the rotating shaft 43; a return spring 44 is sleeved on the rotating shaft 43, and one end of the return spring 44 is fixedly connected to the air collecting ring 34, and the other end is fixedly connected to the shielding sheet 6. When the return spring 44 is in an unloaded state, the shielding sheet 6 is in a vertical state. In this embodiment, when the decorative surface layer is covered on the cushion layer 3, the decorative surface layer applies a downward pressure to the shielding sheet 6 (when the decorative surface layer includes the seat surface layer 2 and the table surface layer 1, the seat surface layer 2 applies a downward pressure to the shielding sheet 6), and the shielding sheet 6 rotates downward around the rotating shaft 43, and the return spring 44 is in a loaded state. When the decorative surface layer is opened to expose the cushion layer 3 to the outside, the shielding sheet 6 automatically stands up under the action of the return spring 44, and the return spring 44 is in an unloaded state. The return spring 44 can be a torsion spring.

[0063] Optionally, in the above embodiment including the splash-proof curtain, an opening is provided on the splash-proof curtain at a position corresponding to the shielding sheet 6 to ensure that the shielding sheet 6 can work normally.

[0064] In the above solution, by providing the shielding sheet 6, urine can be prevented from overflowing during defecation, thereby avoiding contamination of the environment around the device and improving the user's experience.

[0065] For example, referring to Figure 3 , Figure 11-14 The collecting assembly comprises a collecting box 5, a cover plate 19 and a driving mechanism; the driving mechanism is used to drive the cover plate 19 to move horizontally towards or away from the collecting box 5; a flushing hole 49 is provided at the front side of the bottom of the collecting box 5, and a plurality of water injection holes 45 are provided at the rear side of the collecting box 5, and the water injection holes 45 are connected to the water tank 10; both sides of the cover plate 19 extend downward to form an extension part 55, and a slide groove 57 is provided inside the extension part 55; protrusions 67 adapted to the slide groove 57 are provided at both ends of the collecting box 5; the protrusion 67 is slidably connected to the slide groove 57.

[0066] In some embodiments, the water injection hole 45 is arranged to be tilted downward to prevent excrement and urine from flowing back along the water injection hole 45 when water is injected into the collection box 5 for flushing.

[0067] Optionally, the collection box 5 is detachably connected above the feces storage box.

[0068] Optionally, the upper surface of the collecting box 5 is provided with a pin hole matching with the positioning pin.

[0069] exist Fig.11 In the illustrated embodiment, the front and rear sides of the cover plate 19 extend downward to form an extension portion 55 .

[0070] In this example, when the user is ready to defecate, the driving mechanism can be used to control the cover plate 19 to move away from the collection box 5, so that the collection box 5 is connected to the upper feces collecting ring 4. After the user has finished defecating, the driving mechanism can be used to control the cover plate 19 to move toward the collection box 5, so that the cover plate 19 closes the collection box 5.

[0071] Optionally, a sealing ring is provided on the collection box 5, and when the cover plate 19 moves above the collection box 5, the top of the sealing ring contacts the bottom of the cover plate 19. By providing the sealing ring, the sealing effect on the collection box 5 can be improved, and the smell inside can be further prevented from overflowing.

[0072] Optionally, the operation of the water tank 10 injecting water into the collection box 5 through the water injection hole 45 is performed after the cover plate 19 covers the collection box 5. Thus, the sealing effect of the cover plate 19 on the collection box 5 can be used to prevent water or feces and urine from overflowing during the flushing process.

[0073] In this embodiment, the water injection hole 45 is communicated with the water tank 10. It can be understood that the water injection hole 45 can be specifically communicated with the water pump 60 of the water tank 10, and the water is pumped into the collection box 5 by the water pump 60.

[0074] Optionally, the drive mechanism can be controlled by a controller or an independent start-stop switch to enable it to be turned on when the user uses the toilet and turned off after the user finishes using the toilet.

[0075] By matching the collection box 5 with the cover 19, the above solution can use the cover 19 to close the collection box 5 when the toilet is not needed, thereby preventing the collection box 5 and the feces storage box connected thereto from odor overflowing. This helps to further improve the environmental harmony of the overall device.

[0076] For example, Fig.14 As shown, a water inlet hole 52 is provided on one side of the cover plate 19, and a plurality of flushing holes 53 are provided at the bottom of the cover plate 19. The water inlet hole 52 is connected to the water tank 10. In this embodiment, when flushing is required, the cover plate 19 can be closed first (i.e., the cover plate 19 is moved above the collection box 5 to close the collection box 5), and then the flushing hole 53 at the bottom of the cover plate 19 and the water injection hole 45 on the collection box 5 are used to flush water into the collection box 5. This method of flushing the collection box 5 in different directions can avoid the presence of feces and urine residues in the collection box 5, so that the collection box 5 can be flushed more thoroughly.

[0077] For example, referring to Figure 3 , 4, 11, 14, the driving mechanism includes a driving shaft 47, a driving gear 46 and a driving motor 27. The driving shaft 47 is rotatably arranged on one side of the collection box 5, and there are two driving gears 46, which are respectively installed at both ends of the driving shaft 47. The bottom of the extension portion 55 of the cover plate 19 has a rack 56 adapted to the driving gear 46, and the driving gear 46 is meshed with the rack 56. The driving motor 27 is connected to the driving shaft 47 to drive the driving shaft 47 to rotate, and then use the driving gear 46 to drive the cover plate 19 to move.

[0078] The installation position of the drive motor 27 can be set as needed. For example, it can be installed on the collection box 5, or for another example, it can be installed on the fixed frame. Figure 4 In the illustrated embodiment, the drive motor 27 is mounted on a fixed frame.

[0079] In this example, the drive motor 27 is connected to the drive shaft 47. Specifically, the drive motor 27 can be directly connected to the drive shaft 47, or can be connected to the drive gear 46 (for example, the output shaft of the drive motor 27 is meshed with the drive gear 46) to achieve indirect connection with the drive shaft 47. The specific connection method can be selected according to the actual working conditions and will not be described in detail.

[0080] Optionally, the drive motor 27 can be connected to a driver or an independently arranged switch to realize the control of the movement of the cover plate 19, which will not be described in detail.

[0081] The driving mechanism of the above technical solution has a simple structure and high driving efficiency, and can realize driving of the cover plate 19 .

[0082] For example, Fig.14 As shown, an image recognition device 54 is provided at the bottom of the cover plate 19. Fig.15 As shown, a water pump 60 is provided on the water tank 10, and the water in the water tank 10 is input to the collection box 5 and the cover plate 19 through the water pump 60. The hidden flush toilet also includes a controller. The controller is connected to the image recognizer 54 and the water pump 60 respectively. The controller is used to: in response to the user's flushing instruction, control the water pump 60 to pump water to the collection box 5 and the cover plate 19 to flush the feces and urine once; after the flushing is completed, use the image recognizer 54 to collect the image in the collection box 5, and determine whether there is residual feces and urine in the collection box 5 according to the image; when there is residual feces and urine in the collection box 5, control the water pump 60 to pump water to the collection box 5 and the cover plate 19 again to flush the feces and urine for a second time. This helps to ensure the cleaning effect and improve the user experience.

[0083] Optionally, the user's flushing command can be input into the controller using a button of the controller. For example, a flushing button can be provided on the controller. The flushing button can be provided on one side of the cabinet 18, or on the cushion layer 3. When the user presses the flushing button, the controller receives the flushing command.

[0084] Optionally, the controller is connected to the driving mechanism to control the driving mechanism to open or close the cover 19. The controller is used to: open the cover 19 in response to an opening instruction input by the user; and close the cover 19 in response to a closing instruction input by the user.

[0085] The opening instruction and the closing instruction can be input into the controller by pressing the corresponding button of the controller. In some embodiments, the closing instruction can be a flushing instruction. In this embodiment, the operation of controlling the water pump 60 executed by the controller to pump water to the collection box 5 and the cover 19 to flush the feces and urine once is performed after the cover 19 is closed. In other words, in the scheme of this embodiment, after the user has finished defecation, he can press the flush button to input the flushing instruction. After receiving the flushing instruction, the controller first controls the drive mechanism to close the cover 19. After the cover 19 is closed, the water pump 60 is controlled to flush the collection box 5 (once or twice). This centralized control method can simplify the operation, improve the user experience, and can be particularly suitable for use by the elderly.

[0086] For example, referring to Figure 3-5 , 11, 12, a fixing strip 20 is detachably mounted on the fixing frame 7. Both the front and rear sides of the collecting box 5 are provided with assembly grooves 48 adapted to the fixing strip 20. The assembly grooves 48 cooperate with the fixing strip 20 to fix the collecting box 5 on the fixing frame 7. The fixing strip 20 can be fixed on the fixing frame 7 by means such as threaded connection, plug-in connection, and clamping connection, which will not be described in detail.

[0087] In the solution of this example, considering that the collecting box 5 is detachably connected to the top of the feces storage box, in order to prevent the collecting box 5 from being affected when the feces storage box is taken out separately, the collecting box 5 is fixed to the fixing frame 7 through the assembly groove 48 and the fixing strip 20. This fixing method has a simple structure and can facilitate the disassembly and maintenance of the feces storage box.

[0088] For example, Fig.13 As shown, the flushing hole 49 is circular, and a guide portion 51 for conveying feces and urine to the feces storage box is connected below the flushing hole 49. The guide portion 51 is rectangular, and the size of the guide portion 51 is larger than the flushing hole 49. Therefore, in the process of conveying feces and urine into the feces storage box, it can be avoided that the feces and urine are attached to the wall on the guide portion 51, causing inconvenience in later processing.

[0089] For example, referring to Fig.16 , 17The feces storage box includes a feces storage box body 9, an insert plate 64 and an opening and closing mechanism; a feces injection port 63 is arranged on the top of the feces storage box body 9, and the feces injection port 63 is connected to the collecting component; the insert plate 64 is slidably arranged on the feces storage box body 9; the opening and closing mechanism is used to drive the insert plate 64 away from the feces injection port 63 when the feces storage box body 9 enters the cabinet 18, and drive the insert plate 64 to close the feces injection port 63 when the feces storage box body 9 is taken out of the cabinet 18.

[0090] Optionally, guide rails 50 are provided on both sides of the feces collecting box, and a guide groove 61 adapted to the guide rails 50 is provided on the top of the feces storage box body 9. The guide rails 50 are inserted into the guide grooves 61 to relatively fix the feces collecting box and the feces storage box body 9.

[0091] Optionally, a pull groove 69 may be provided at the front end of the stool storage box body 9 to facilitate taking the stool storage box body 9 out of the cabinet 18 .

[0092] In the solution of this example, when the feces storage box is taken out, the top plug plate 64 can be used to close the feces injection port 63 by the opening and closing mechanism, so as to prevent the feces and urine from generating odor and escaping to the surrounding environment from the feces injection port 63 after the feces storage box is taken out. In addition, the opening and closing mechanism can drive the plug plate 64 away from the feces injection port 63 when the feces storage box body 9 enters the cabinet 18, thereby ensuring the normal operation of the feces storage box.

[0093] Optionally, in the embodiment where the above-mentioned collecting assembly includes the collecting box 5 , when the collecting box 5 is installed above the feces storage box, the feces punching hole 49 is located above the feces injection port 63 .

[0094] For example, referring to Figure 3 , 16 -18, a slot 73 is provided at the top of the stool storage box body 9, and the plug plate 64 is slidably connected in the slot 73; the opening and closing mechanism includes a push block 24 and a driving spring 72; a push groove 26 is provided at the top of the stool storage box body 9; the push block 24 passes through the push groove 26 and goes deep into the stool storage box body 9, and the lower end of the push block 24 is connected to the plug plate 64; one end of the driving spring 72 is connected to the rear side of the plug plate 64, and the other end is connected to the slot 73; a push rod 25 is provided on the fixed frame; when the stool storage box body 9 enters the cabinet 18, the push rod 25 contacts the push block 24, so that the push block 24 slides along the push groove 26 to drive the plug plate 64 away from the stool injection port 63; when the stool storage box body 9 is taken out of the cabinet 18, the plug plate 64 closes the stool injection port 63 under the action of the driving spring 72.

[0095] In such Figure 3 In the illustrated embodiment, the push rod 25 is connected to the fixing frame 7. Specifically, a cross bar is connected between the two fixing frames 7, and the push rod 25 is fixed on the cross bar.

[0096] In such Fig.18In the embodiment shown, a guide shaft 71 is provided in the slot 73, and the axis of the guide shaft 71 is provided in the front-back direction; a plug hole is provided at the rear side of the plug plate 64, and the guide shaft 71 penetrates into the plug plate 64 through the plug hole. The driving spring 72 is sleeved on the guide shaft 71, and one end of the driving spring 72 penetrates into the plug hole and is connected to the plug plate 64, and the other end is fixedly connected to the slot 73 through the guide shaft 71. When the plug plate 64 is away from the feces injection port 63, the driving spring 72 is in a loaded state. When the plug plate 64 closes the feces injection port 63, the driving spring 72 is in an unloaded state. The lower end of the push block 24 is connected to the plug plate 64 through the wire drawing 70. When the feces storage box body 9 enters the cabinet 18, the push rod 25 contacts the push block 24, so that the push block 24 slides along the push groove 26, and the push block 24 pulls the plug plate 64 to move in a direction away from the feces injection port 63 through the wire drawing 70, and at the same time, the driving spring 72 is in a compressed state. When the feces storage box body 9 is taken out from the cabinet 18 , since the push rod 25 is away from the push block 24 , the push block 24 no longer pulls the plug plate 64 , the drive spring 72 is reset, and the plug plate 64 closes the feces injection port 63 under the action of the drive spring 72 .

[0097] The driving mechanism of the above technical solution has a simple structure and can automatically open or close the feces filling port 63 according to the user's movement of the feces storage box, thereby helping to improve the user experience.

[0098] Alternatively, if Fig.17 As shown, a handle 68 is installed on the stool storage box body 9, and a placement groove 66 for placing the handle 68 is provided on one side of the stool storage box body 9. After the stool storage box body 9 is taken out, the handle 68 can be used to lift the stool storage box, thereby facilitating the transportation of the stool storage box.

[0099] For example, referring to Fig.17 and 19 A fixing ring 65 is rotatably provided on the top of the stool storage box body 9; the fixing ring 65 is located on the side of the push groove 26 away from the cabinet 18; the fixing ring 65 is used to rotate toward the push groove 26 to be sleeved on the push block. When the fixing ring 65 is sleeved on the push block, the stool injection port 63 is in an open state.

[0100] When the user needs to dump the feces storage box, the feces storage box can be taken out of the cabinet 18, and then the pushing block is pushed to open the feces injection port 63, and the fixing ring 65 is set on the pushing block to prevent the feces injection port 63 from being closed. At this time, the feces injection port 63 can be used as a pouring port of the feces storage box to pour the feces and urine stored therein. Therefore, this solution can facilitate the user to dump the feces storage box by setting the fixing ring 65. And this design method does not need to set a separate pouring port, thereby helping to simplify the structure of the feces storage box and reduce costs.

[0101] Optionally, a sealing ring may be provided above the feces injection port 63. When the collection box 5 is installed above the feces storage box body 9, the top of the sealing ring abuts against the guide portion 51 below the feces punching hole 49 of the collection box 5. This helps to improve the overall sealing performance and prevent odor or feces from leaking from the connection between the two. The sealing ring may be made of a flexible and deformable material such as rubber, which will not be described in detail.

[0102] For example, Fig. 20 As shown, a one-way flushing port 75 is provided on one side of the stool storage box body 9, and a cleaning pipe 74 is provided inside the stool storage box body 9. The cleaning pipe 74 is connected to the one-way flushing port 75, and a side wall of the cleaning pipe 74 is provided with multiple openings with different directions.

[0103] It can be understood that the one-way flushing port 75 is a one-way locked pipeline, that is, water is only allowed to flow into the stool storage box body 9 from the one-way flushing port 75, and water cannot flow out of the stool storage box from the one-way flushing port 75. This structure can be achieved by connecting a one-way valve on one side of the stool storage box body 9, and of course, it can also be achieved by other structural design methods, which will not be repeated.

[0104] When it is necessary to clean the interior of the feces storage box body 9, water can be injected through the one-way flushing port 75, and the water flows into the cleaning pipe 74 and flushes into the interior of the feces storage box body 9 from different directions along the openings on the cleaning pipe 74, thereby achieving comprehensive cleaning of the interior of the feces storage box body 9. The cleaned waste water can be discharged through the feces injection port 63.

[0105] Optionally, the hidden flush toilet further comprises an ultrasonic generator 76 for cleaning the stool storage box. Fig.21 As shown, the ultrasonic generator 76 is disposed at the bottom of the fixed plate (specifically, at the bottom of the upper support plate 21). It can be understood that since the stool storage box is detachably connected to the fixed plate, the ultrasonic generator 76 can transmit ultrasonic waves to the stool storage box body 9 via the fixed plate to achieve cleaning of the interior of the stool storage box body 9.

[0106] The structure of the above technical solution can simplify the cleaning operation of the internal space of the stool storage box body 9, thereby helping to improve the user experience.

[0107] For example, Figure 4 As shown, the hidden flush toilet also includes a lifting assembly 22 and a lifting motor 77. The lifting assembly 22 is arranged below the stool storage box, and the lifting motor 77 is transmission-connected to the lifting assembly 22. The lifting assembly 22 is used to drive the collection assembly to move upward to reduce the distance between the collection box 5 and the air collecting ring 34.

[0108] In such Figure 4In the illustrated embodiment, the lifting assembly 22 is installed between the upper support plate 21 and the lower support plate 23, and the lifting motor 77 can be fixed below the upper support plate 21. The lifting assembly 22 can be composed of two X-shaped hinged connecting rod groups. For any one of the connecting rod groups, the lower end of one of the connecting rods in the connecting rod group can be hinged on the lower support plate 23, and the upper end can be slidably set on the lower surface of the upper support plate 21. The upper end of the other connecting rod can be hinged on the lower surface of the upper support plate 21, and the lower end can be slidably set on the lower support plate 23. Those skilled in the art can understand its specific setting method and lifting principle, which will not be repeated. In an embodiment not shown in the present invention, the lifting assembly 22 can also adopt other mechanisms, for example, it can be a plurality of hydraulic telescopic rods. In this case, the lifting motor 77 can be a hydraulic motor for driving the hydraulic telescopic rods to extend and retract.

[0109] The inventors found during the research that Fig. 22 As shown, when the cover plate 19 is removed from the collection box 5, a space gap L is formed between the top of the collection box 5 and the air collecting ring 34. At this time, if the defecation operation is performed directly, due to the existence of the space gap L, feces and urine may splash out from the gap and pollute the surrounding parts, and it will also affect the waste gas treatment effect of the air collecting ring 34. When the solution in which a positioning pin 37 is provided at the bottom of the air collecting ring 34 as described above is adopted, the size of the space gap L may also be different when different users sit on the cushion layer 3. In the solution of this example, after the user sits on the cushion layer 3, the upper support plate 21 and the feces storage box and collection box 5 thereon can be moved upward by the lifting assembly 22 until the top of the collection box 5 contacts the air collecting ring 34. In this way, the airtightness between the air collecting ring 34 and the collection box 5 can be improved to prevent feces and urine and waste gas from overflowing from the gap.

[0110] Furthermore, the hidden flush toilet also includes a controller. A pressure sensor is provided at the bottom of the air collecting ring 34. The controller is respectively connected to the pressure sensor and the lifting motor 77. The controller is used to: in response to the defecation preparation instruction input by the user, control the lifting assembly 22 to work by the lifting motor 77 so that the collection box 5 rises; when receiving the pressure signal sent by the pressure sensor, control the lifting motor 77 to stop working. At this time, the bottom of the air collecting ring 34 contacts the top of the collection box 5. In other embodiments, a limit switch is provided at the bottom of the air collecting ring 34. When the bottom of the air collecting ring 34 contacts the top of the collection box 5, the limit switch is triggered. The controller is respectively connected to the limit switch and the lifting motor 77. The controller is used to: in response to the defecation preparation instruction input by the user, control the lifting assembly 22 to work by the lifting motor 77 so that the collection box 5 rises; when the limit switch is triggered, control the lifting motor 77 to stop working.

[0111] Optionally, the user's defecation preparation instructions can be input into the controller using the buttons of the controller, which will not be described in detail.

[0112] In this embodiment, a pressure sensor can be used to sense whether the bottom of the air collecting ring 34 is in contact with the top of the collection box 5, so that the lifting motor 77 can be controlled more accurately. This solution helps to further ensure the airtightness between the air collecting ring 34 and the collection box 5, thereby further preventing feces and urine from splashing out.

[0113] For example, Fig.15 As shown, a handle 58 is provided on the front side of the water tank 10, and a water filling port is provided at the front position of the top of the water tank 10, and a water filling cap 59 is installed on the water filling port. Therefore, when filling water into the water tank 10, it is only necessary to pull the water tank 10 out of a part of the cabinet 18. After the water filling is completed, the water tank 10 can be quickly reset.

[0114] Optionally, a water level sensor is provided in the water tank 10. A speaker and a prompt light are provided on the cabinet 18. The water level sensor is connected to the controller, and the controller is connected to the speaker and the indicator light 84. When the water level sensor senses that the water in the water tank 10 is insufficient, the controller can prompt the user to add water in time through the speaker and the indicator light 84.

[0115] For example, Fig.23 As shown, the hidden flush toilet also includes a waste paper barrel. The waste paper barrel includes a barrel body 11 and an upper cover 78, both of which are mounted on the inner side wall of the cabinet body 18, and the upper cover 78 is located above the barrel body 11. A waste paper inlet 79 is provided on one side of the upper cover 78. A waste paper slot is provided on the side wall on which the upper cover 78 is mounted, and the waste paper slot is connected to the waste paper slot 79. Waste paper can enter the barrel body 11 through the waste paper slot.

[0116] The cylinder 11 can be installed on the inner wall of the cabinet 18 by plugging, snapping, threading, etc. Figure 1 , 23 In the illustrated embodiment, a first partition 16 and a second partition 15 are provided in the cabinet 18. The first partition 16 is horizontally provided in the cabinet 18 to divide the cabinet 18 into two layers, an upper layer and a lower layer.
