At present, in a common toilet bowl, the height from the upper edge of a bowl shell to the ground is about 400mm, which is slightly less than the length of a lower leg of an adult, so that when a user sits on the toilet bowl, the upper leg is approximately parallel to the ground, so that the hip and the thigh of the user sink in the annular upper edge, and the lower abdomen and the leg of the user continuously exert force in the excretion process, thereby improving the excretion fluency to a certain extent. However, the human phalangeal rectal muscle is only tensed when the thigh and lower leg are folded to a greater extent, e.g. when excreting in a crouched position. Therefore, when the user excretes in a sitting posture, the phalangeal and rectal muscles of the user are usually not as tight as the phalangeal and rectal muscles in a squatting posture, and the smoothness of the defecation in the sitting posture is lower than that of the defecation in the squatting posture.

The squatting type toilet bowl of the embodiment is smaller than the normal toilet bowl in height. Specifically, the height of the squatting pan of the embodiment is 200-250 mm. When the user sits on the squatting type toilet bowl, the folding degree of the thighs and the shanks is higher, and the thighs are bent towards the trunk, so that the tightening degree of the phalangeal rectal muscles is higher, and the excretion smoothness is convenient to improve.

Specifically, referring to fig. 1, the squat toilet of the present embodiment includes a toilet body 100 and a dirt blocking member 110, a dirt accommodating chamber is provided in a bowl housing 101 of the toilet body 100, and the dirt blocking member 110 is disposed at a front end of the bowl housing 101.

The upper port of the toilet bowl body 100 is provided with a ring-shaped inner edge, which specifically comprises a bearing edge 104 located at the front end of the toilet bowl body 100 and an upper edge 102 located at the rear end of the toilet bowl body 100, wherein the bearing edge 104 is arranged higher than the upper edge 102. The front end of the upper edge 102 is tilted upwards, i.e. the front end of the upper edge 102 is bent towards the bearing edge 104, the front end of the upper edge 102 is connected with the bearing edge 104 and forms a bearing part at the connection, and the dirt block 110 is connected on the bearing edge 104.

In addition, since the user may leak the filth discharged from the front end of the toilet body 100 in the squatting position, the filth stopper 110 provided at the front end of the toilet body 100 in the present embodiment can effectively prevent the above-mentioned situation from occurring.

Specifically, referring to fig. 2, the dirt stop 110 of the present embodiment may specifically include a dirt stop housing 111, and a middle rear portion of the dirt stop housing 111 is upwardly arched. The side of the dirt blocking housing 111 facing the toilet bowl body 100 is provided with a connecting edge 116, the shape of the connecting edge 116 is matched with the shape of the bearing edge 104, the dirt blocking housing 111 is mounted on the toilet bowl body 100 by the connection of the connecting edge 116 and the bearing edge 104, and the connecting edge 116 and the bearing edge 104 can be specifically connected by gluing.

The dirt shield 111 is provided with a rear edge 112 on the side facing the upper edge 102, i.e. the rear edge 112 is located on the rear side of the dirt shield 111. The rear edge 112 may be a semicircular ring structure having an opening at a position at a lower side and forming a jaw 114 at a rear side of the dirt shield case 111, the jaw 114 being disposed toward a rear end of the toilet body 100. When a user squats on the toilet of the present embodiment, especially a male user, the filth discharged therefrom can enter the filth receiving chamber of the toilet body 100 from the fork 114, thereby preventing the filth from leaking out.

As a further optimization of the dirt shield casing 111, the dirt shield casing 111 is further provided with a dirt attracting portion 113. The contamination leading portion 113 may be specifically disposed on the connecting edge 116 to form an integrated structure; it is also possible that the edge of the connecting edge 116 extends into the dirt-holding chamber, thereby forming the dirt-guiding portion 113. The central portion of the soil guide portion 113 is recessed downward, and a soil guide opening 115 extending toward the soil receiving chamber is formed below the soil blocking housing 111. After the dirt discharged by the user enters the fork opening 114 and is blocked by the dirt guiding portion 113, the dirt finally flows into the dirt accommodating cavity of the toilet bowl body 100 from the dirt guiding opening 115 under the guiding of the dirt guiding portion 113, so that the dirt is not leaked or splashed.

In order to clean the dirt stopper 110 in time and prevent the dirt from remaining on the dirt guide 113 to be smelled, the first cleaner 320 may be provided on the dirt stopper 110. Referring to fig. 3, the first cleaner 320 may be disposed on the trailing edge 112, and may be disposed inside the trailing edge 112 such that the water spray of the first cleaner 320 is disposed toward the dirt attracting portion 113.

As a further optimization, the first scrubber 320 may be provided in plurality, for example, two. When the first cleaners 320 are provided in two, two first cleaners 320 may be respectively located on both sides of the fork 114, that is, two first cleaners 320 may be located on opposite sides of the trailing edge 112. When the dirt guiding part 113 is cleaned, the two first cleaners 320 respectively clean the two sides of the dirt guiding part 113, and then the cleaned sewage flows into the dirt containing cavity of the toilet bowl body 100 from the dirt guiding opening 115, so that the cleaning efficiency is higher.

The rear end of the rear edge 112 of the dirt retention housing 111 may be curved, in particular downwardly curved, towards the upper edge 102. The rear end of the rear edge 112 is connected with the front end of the upper edge 102 which is tilted upwards, so that an integral bearing part is formed, the contact area of the hip and the thigh of a user sitting on the toilet is further increased, and the use comfort of the user is improved.

As a further optimization, the rear end of the upper edge 102 may also tilt upwards, so that the upper edge 102 and the rear edge 112 integrally form a saddle-shaped structure with a concave middle section, and the saddle-shaped structure can maximally increase the contact area between the hip and thigh parts of the user sitting on the toilet, so as to conform to the hip and thigh part structure of most users, reduce the stress burden of the hip and thigh parts when the user is using, and facilitate the exertion of excretion by the user.

The sewage holding cavity and the sewage discharge structure of the squatting type toilet bowl of the embodiment can be structures commonly used in the related field, namely, the sewage outlet 120 is provided with a water seal structure, and simultaneously, sewage is discharged in a falling or siphon type mode, for example, the sewage outlet structure disclosed in the Chinese patent document with the application number of 2008101427831.

But adopt the toilet bowl of water seal structure, owing to there is certain difference in height, if directly go into water when the filth falls into in the toilet bowl, splash easily, seriously influence user's use and experience. Therefore, as a further optimization of the present embodiment, the dirt conveying mechanism 200 may be disposed in the dirt holding cavity, and after the dirt falls into the dirt holding cavity, the dirt conveying mechanism 200 can convey the dirt to the drain 120 in time, so that the splashing of the dirt in the dirt holding cavity can be effectively prevented.

It should be noted that the dirt transport mechanism 200 may be a dirt transport mechanism 200 commonly used in the related art, such as the belt transport mechanism disclosed in chinese patent application No. 2014205812754 and chinese patent application No. 2008101427831. However, when the above-mentioned filth transfer mechanism 200 is used, it is inevitable to provide an airtight structure having a water seal structure at the drain port to prevent the backflow of odor in the sewage, and therefore, a large amount of water is required to be discharged into the drain port in a short time during the filth discharge, so that a pressure difference is formed at the water seal structure, and finally, filth is pushed into the sewage to complete the discharge of filth in the toilet bowl.

As another embodiment, the present embodiment provides another airtight structure, in which a dirt-separating plate 250 is provided above the drain port 120 to be opened and closed, and is opened to allow dirt to be discharged from the dirt-containing chamber when a user uses the toilet, and is closed to prevent backflow of odor in the sewage after the user finishes using the toilet. Therefore, the drain 120 of the present embodiment can be directly connected to a sewer without additionally providing a water seal structure, so that a large amount of water is not required to be used to squeeze sewage into the sewer during sewage disposal, thereby saving water consumption.

Referring to fig. 4, the dirt conveying mechanism 200 of the present embodiment may specifically include a driving roller 212, a driven roller 211 and a conveying belt 220, the conveying belt 220 is sleeved on the driving roller 212 and the driven roller 211, and the driving roller 212 may be driven by a driving member to rotate and simultaneously drive the conveying belt 220 to rotate, so as to convey the dirt falling on the dirt conveying mechanism 200 into the lower water inlet.

The front end of the dirt conveying mechanism 200 is arranged higher than the rear end, and specifically, the driving roller 212 is arranged at the rear end of the dirt containing cavity, the driven roller 211 is arranged at the front end of the dirt containing cavity, and the driven roller 211 is arranged higher than the driving roller 212.

The soil discharge port 115 of the soil discharge portion 113 is engaged with the front end of the soil transfer mechanism 200. The sewage flowing out of the sewage guide port 115 can flow into the front end of the sewage transport mechanism 200 and flow to the rear end of the sewage transport mechanism 200 under the influence of gravity.

The sewage outlet 120 is disposed at the lower side of the rear end of the bowl housing 101, the sewage outlet 120 is disposed toward the rear end of the sewage conveying mechanism 200, the sewage outlet 120 is disposed below the rear end of the sewage conveying mechanism 200, and the sewage flowing to the rear end of the sewage conveying mechanism 200 can fall into the sewage outlet 120 and be discharged.

The driving roller 212 is further provided with a friction wheel 240 on the rotating shaft, and the friction wheel 240 can rotate synchronously with the driving roller 212. The dirt separating plate 250 is movably connected to the dirt discharging plate 103 at the bottom of the toilet bowl body 100, the dirt discharging plate 103 is communicated with the drainage port 120, and the friction wheel 240 is in transmission connection with the dirt separating plate 250 and controls the dirt separating plate 250 to open and close.

Specifically, when the driving roller 212 is driven by the driving member to rotate, the transmission belt 220 starts to move, the dirt on the transmission belt 220 starts to move towards the lower nozzle 120, and at the same time, the friction wheel 240 also starts to rotate, the dirt separating plate 250 starts to move under the friction force of the friction wheel 240 to open the lower nozzle 120, and then the dirt leaves the transmission belt 220 and falls into the lower nozzle. After the sewage discharge is completed, the driving roller 212 rotates reversely, and the friction wheel 240 drives the sewage separation plate 250 to move so as to close the sewage outlet 120.

As another mode, referring to fig. 5 and 6, a slide rail may be disposed on the sewage draining plate 103, the sewage separating plate 250 is disposed on the slide rail, and the front end of the sewage separating plate 250 is disposed higher than the rear end, so that the sewage draining plate 103 can slide toward the rear end of the sewage separating plate 250 by virtue of its own gravity when not subjected to the friction force of the friction wheel 240, thereby sealing the sewage draining port 120. At this time, after the sewage discharge is finished, the driving roller 212 does not need to rotate reversely to drive the friction wheel 240 to drive the sewage separation plate 250 to move so as to close the sewage outlet 120.

To achieve the above purpose, the distance from the upper side of the dirt-separating plate 250 to the center point of the friction wheel 240 should be different during the movement of the dirt-separating plate. Specifically, as an embodiment, the thickness of the dirt separator 250 gradually increases from the front end to the rear end thereof, so that the side of the dirt separator 250 facing the friction wheel 240 is sloped. When the dirt separating plate 250 is in a closed state, the friction wheel 240 is in side contact with the dirt separating plate 250, when the friction wheel 240 rotates, the dirt separating plate 250 moves towards the upper front end of the dirt discharging plate 103, the upper side of the dirt separating plate 250 is gradually separated from the friction wheel 240, the friction acting force of the friction wheel 240 is gradually reduced, and when the friction force and the gravity of the dirt separating plate 250 are balanced, the dirt separating plate 250 stays at the middle section of the dirt discharging plate 103, so that the opening of the sewage draining port is completed. After the sewage discharge is completed, the friction wheel 240 stops rotating, the friction force acting on the sewage separation plate 250 disappears, and the sewage separation plate 250 slides downwards under the action of self gravity to complete the closing of the sewage outlet.

As another embodiment, the side of the dirt-separating plate 250 facing the friction wheel 240 has a step structure, that is, the side of the dirt-separating plate 250 facing the friction wheel 240 has two planes with different heights, and a section connecting the two planes. The distance from the upper step surface of the step structure to the center point of the friction wheel 240 is equal to the radius of the friction wheel 240, that is, the distance from the relatively higher plane of the two planes to the center point of the friction wheel 240 is equal to the radius of the friction wheel 240, or may be slightly greater than the radius of the friction wheel 240 to increase the friction force generated when the friction wheel 240 rotates. Referring to fig. 7, when the dirt-separating plate 250 moves from the closed state to the dirt-discharging state, i.e., from the position a to the position b in the figure, the friction wheel 240 is out of contact with the upper step surface of the stepped structure and interacts with the cross section of the stepped structure to provide its thrust against gravity, so that the dirt-separating plate 250 reaches the equilibrium state.

The conveying belt 220 may be provided at both sides with the blocking plates 230, and the blocking plates 230 are disposed perpendicular to the rotational axis of the driving roller 212 and parallel to the conveying direction of the conveying belt 220. The baffle 230 functions to allow the sewage flowing out of the sewage guide port 115 to flow down the conveyor belt 220, thereby wetting the conveyor belt 220 and reducing the adhesion of the sewage on the conveyor belt 220.

In order to achieve timely cleaning of the conveyor belt 220 and prevent the filth from remaining on the conveyor belt 220 and smelling, a second cleaner 310 may be provided on the drain plate 103, and a water spray port of the second cleaner 310 is provided toward the conveyor belt 220 for spraying a cleaning water solution to the conveyor belt 220 to complete cleaning of the conveyor belt 220.

Water supply pipes of the second and first cleaners 310 and 320 are connected to an external water source, and a solenoid-operated valve 330 is provided on the water supply pipe to control the cut-off and communication of the water supply to the second and first cleaners 310 and 320.

The driving member of the driving roller 212 may be a stepping motor, and the stepping motor may be disposed in the control box 300, and the stepping motor is in transmission connection with the driving roller 212, specifically, may be a belt transmission, or a chain transmission. The stepper motor is activated or deactivated based on signals from sensor 410.

As another embodiment, the driving roller 212 may be a motorized roller, which may be a motorized roller commonly used in the related art, and the motorized roller may be started or stopped according to a signal returned by the sensor, so as to drive the transmission belt 220 and the friction wheel 240 to move and stop, and at this time, an additional driving member is not required to be provided to drive the motorized roller.

When the squatting type toilet bowl of the embodiment is used, the specific processes of cleaning and discharging sewage are as follows:

when the sensor 410 detects that the dirt enters the dirt containing cavity and falls on the conveying belt, a signal is transmitted to the signal amplifier, then the electromagnetic control valve is opened, the water supply pipeline is communicated with water, the first cleaner 320 sprays cleaning water liquid to the dirt guiding part 113, and the second cleaner sprays cleaning water liquid to the conveying belt 220;

meanwhile, the stepping motor starts to operate and drives the driving roller 212 to move, then the transmission belt 220 and the friction wheel 240 start to move, the transmission belt 220 conveys the dirt to the rear end of the transmission belt, the friction wheel 240 applies friction force to the dirt separating plate 250 to drive the transmission belt to move, so that the dirt separating plate is in a dirt discharge state, and the sewage outlet 120 is opened;
