Description

Technical Field

[0001] This invention relates to the field of squat toilet technology, and in particular to a squat toilet that does not flush when urinating but flushes when defecating. Background Technology

[0002] After more than a century of development, flush toilets have almost perfected their technology, especially in terms of user experience, offering cleanliness, hygiene, comfort, and convenience. They have contributed to human health and well-being and are a symbol of urbanization and modern civilization. However, the wastewater from flush toilets enters the environment, causing water pollution and eutrophication. Wastewater treatment plants need to spend enormous amounts of energy and chemicals to treat this pollution. People have long realized that if urine from flush toilets could be collected and prevented from entering the sewer system, the burden on wastewater treatment plants could be greatly reduced. At the same time, the collected urine can be used to extract biological agents and as plant fertilizer.

[0003] In the existing technology, the use of waterless urine collection devices for squat toilets is unreliable, or when flushing with water, some sewage is easily flushed into the urine collector, contaminating the urine. Summary of the Invention

[0016] The beneficial effects of this invention, a waterless urination and water-flushing squat toilet, are as follows: When using the toilet, urine enters the urine collection tank and then passes through the oil-sealed urination channel into the urination guide, eliminating the need for flushing. Defecation, like in a regular toilet, is flushed into the main drain pipe of the squat toilet. Because the urine collection tank and urination channel are completely isolated from the water-flushing defecation, they do not interfere with each other. The urine collection tank is isolated from the sewer by an oil seal, solving the problems of urine odor and sewer backflow. Like a regular water-flushing toilet, the S-shaped water seal isolates the toilet from the sewer to prevent backflow of odor.

[0017] The beneficial effects of the waterless urination and water-flushing squat toilet of the present invention are as follows: In use, firstly, the outer edge of the urine collection liner is engaged with the frame edge of the squat toilet. During engagement, the catheter and ureter are in contact. At this time, the catheter connector is inserted into the conical plate. When the connector and auxiliary head are in contact, the pressure causes the annular plate to move downward. At the same time, one end of the limiting block slides in the straight groove and the arc groove. Due to the deflection force of the arc groove, the auxiliary head rotates. After the connector and auxiliary head are in contact, one end of the limiting block moves to the end of the arc groove. At this time, the arc hole and the circular hole are on the same plane. Then, the bolt is screwed into the arc hole and the circular hole to ensure the stability of the connection between the connector and the auxiliary head, thus ensuring the quick connection between the urine collection liner and the squat toilet.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0031] Example 1, referring to Figures 1 to 9This is the first embodiment of the present invention. This embodiment provides a waterless squat toilet for urination and a water-flushing squat toilet for defecation, which enables quick connection between the squat toilet 400 and the urination catheterization assembly 100 and improves the stability of the urination catheterization assembly 100 during use. It includes a squat toilet 400 and a urination catheterization assembly 100, and a connecting mechanism 200 for mounting the urination catheterization assembly 100 on the squat toilet 400. The connecting mechanism 200 includes a connector 201 disposed on the urination catheterization assembly 100, and a snap-fit ​​member 202 disposed on the connector 201. The squat toilet 400 is provided with a connecting... The catheterization component 203, which is matched with component 201, is provided with an auxiliary component 204 that engages with the snap-fit ​​component 202. The catheterization component 203 is also provided with a rotating component 205. When installing the catheterization component 100, first align the catheterization component 100 with the frame of the squat toilet 400. At this time, the connector 201 and the catheterization component 203 are connected, so that the squat toilet 400 and the catheterization component 100 are initially fixed. Then, through the cooperation of the snap-fit ​​component 202 and the auxiliary component 204, the catheterization component 100 and the squat toilet 400 are connected more stably. The rotating part 205 is used to engage with the snap-fit ​​part 202 and the auxiliary part 204. The connecting part 201 is also provided with a positioning part 206. The positioning part 206 is used for auxiliary positioning of the connecting part 201 and the catheter part 203. When the catheter assembly 100 and the squat toilet 400 are aligned, the vertical downward force causes the rotating part 205 to rotate due to the deflection force through the inclined groove. At this time, the positioning part 206 is snapped into the catheter part 203, providing secondary positioning for the squat toilet 400 and the catheter assembly 100.

[0032] Specifically, the urinary catheterization assembly 100 includes a urine collection liner 101, with mounting edges 101a integrally formed on both sides of the urine collection liner 101. A partition 101b is integrally formed inside the urine collection liner 101, dividing the urine collection liner 101 into a urination area 101c and a defecation area 101d. A urine baffle 101e is integrally formed at the front end of the urination area 101c, and a connector 201 is disposed on the lower end face of the urination area 101c. The urine baffle 101e is shaped as follows: The hood-shaped structure is installed on the urine collection liner 101. After urine is collected in the main body of the urine collection liner 101, it enters the urine guide 203 through the water outlet of the urine collection liner 101. The connection here is sealed to prevent water from entering. The urine guide pipe extends along the same path as the main sewage pipe. During this time, feces are discharged into the toilet and directly flushed into the main sewage pipe by water. The urine passage and the feces passage do not affect each other and the two channels do not interfere with each other, realizing waterless urine flushing. When using the toilet, urine enters the urine collection tank 101 and flows through the oil-sealed urination channel into the urination guide 203, eliminating the need for flushing. Defecation, like a regular toilet, is flushed into the main drain pipe of the squat toilet 400. Because the urine collection tank 101 and the urination channel are completely isolated from the flushing of feces, they do not interfere with each other. The urine collection tank 101 is isolated from the sewer by an oil seal, solving the problems of urine odor and sewer backflow. Like a regular flush toilet, the S-shaped water seal isolates the toilet from the sewer to prevent backflow. After the first use, about 50 ml of sealing oil can be poured into the urine collection tank 101 to seal the urine odor and sewer backflow. Afterward, sealing oil should be added once a week or once a month.

[0033] Example 2, refer to Figures 1 to 9 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a connection mechanism 200 for a squat toilet that is flushable for urination and flushable for defecation. The connector 201 includes a catheter 201a that is seamlessly welded to the bottom of the urination area 101c. One end of the catheter 201a is fixedly connected to a connector 201b. One end of the connector 201b is integrally formed into a socket joint. The outer wall of the socket joint and the connector 201b form a stepped shape 201c. The inner wall of the socket joint is an inclined surface. The outer wall of the connector and the connector 201b form a stepped shape 201c. The interior of the stepped shape 201c is an inclined surface, which provides a good limiting effect when the connector is inserted. The inclined surface of the connector cooperates with the catheter 203, which makes the catheter 201a have good sealing performance and ensures the stability of the connection. Furthermore, the step of the stepped shape 201c is combined with the parallel surface of the catheter 203, which ensures the firmness of the connection between the outer wall of the connector and the connector 201b.

[0034] Specifically, the snap-fit ​​component 202 includes a first arc-shaped plate 202a integrally formed on both sides of the outer wall of the connector 201b. A first snap-fit ​​plate 202b is integrally formed on the outer wall of the connector 201b, forming a first receiving space 202c with the connector 201b. The first snap-fit ​​plate 202b is arranged in a surrounding shape outside the first arc-shaped plate 202a. The urinary catheter 203 includes a ureter 203a disposed on the squat toilet 400. The front end of the ureter 203a is a telescopic section, allowing it to move downwards when compressed. The ureter 203a has a straight end, which is fixed. An annular edge 203b is integrally formed on the inner wall of the ureter 203a. A conical plate 203c is integrally formed on the upper end face of edge 203b. The conical plate 203c fits into the inner wall of the connector. The auxiliary component 204 includes an auxiliary head 204a disposed on the ureter 203a. Two sets of second arc-shaped plates 204b are integrally formed on the outer wall of the auxiliary head 204a. Second snap-fit ​​plates 204c are symmetrically fixedly connected to the outer wall of the auxiliary head 204a. A second receiving space 204d is formed between the second snap-fit ​​plate 204c and the auxiliary head 204a. The second snap-fit ​​plate 204c is disposed in a surrounding shape outside the second arc-shaped plate 204b. The first receiving space 202c and the second receiving space 204d can both cover the sum of the first arc-shaped plate 202a and the second arc-shaped plate 204b. One end of the first snap-fit ​​plate 202b is fixedly connected to the connector 201b, and the other end of the second snap-fit ​​plate 204c is fixedly connected to the auxiliary head 204a. The first snap-fit ​​plate 202b and the second snap-fit ​​plate 204c are elastic elements and are L-shaped. One end of the L-shape is arc-shaped, so that the first receiving space 202c and the second receiving space 204d can wrap around the sum of the first arc plate 202a and the second arc plate 204b. When the first arc plate 202a and the second arc plate 204b wrap around the first receiving space 202c and the second receiving space 204d, they have a certain squeezing effect, causing them to deform slightly. This ensures that the first snap-fit ​​plate 202b and the second snap-fit ​​plate 204c can clamp the first arc plate 202a and the second arc plate 204b tightly, making the connection between the catheter 201a and the ureter 203a more stable.

[0035] The rotating component 205 includes a collar 205a disposed on the outer wall of the ureter 203a, forming a movable area 205b between the collar 205a and the outer wall of the ureter 203a. An annular plate 205c is fixedly connected to one end of the ureter 203a. A limiting block 205d is integrally formed on the outer wall of the annular plate 205c. A straight groove 205e is provided on the inner wall of the collar 205a, and an arc-shaped groove 205f is provided at one end of the straight groove 205e. The limiting block 205d... The end is slidably connected in the straight groove 205e and the arc groove 205f. A torsion spring 205g is sleeved on the outer wall of the collar 205a. The torsion spring 205g is a carbon spring with high strength and is easy to use in daily work. One end of the torsion spring 205g is set on the step on the inner wall of the collar 205a. The limiting block 205d has an arc hole 205h. A circular hole 205i is provided in the arc groove 205f. Bolts are provided in the arc hole 205h and the circular hole 205i. A collar 205a is fixedly connected to the outer wall of the ureter 203a. The collar 205a provides support and deflection force for the rotating component 205. One end of the limiting block 205d is slidably connected in the straight groove 205e and the arc groove 205f. When the ureter 203a moves downward, it squeezes the auxiliary head 204a. Under pressure, the annular plate 205c moves downward. At the same time, the deflection force of the arc groove 205f drives the auxiliary head 204a to rotate. When the connector 201b and the auxiliary head 204a rotate and fit together, one end of the limiting block 205d moves to the end of the arc groove 205f. At this time, the arc hole 205h and the circular hole 205i are located on the same plane. Then, the bolt is screwed into the arc hole 205h and the circular hole 205i to ensure the stability of the connection between the connector 201b and the auxiliary head 204a.

[0036] The rest of the structure is the same as in Example 1.

[0037] In summary, during use, firstly, the outer edge of the urine collection liner 101 is engaged with the frame edge of the squat toilet 400. During engagement, the catheter 201a is in contact with the ureter 203a. At this time, the insertion point of the catheter 201a is inserted into the conical plate 203c. When the connector 201b and the auxiliary head 204a are in contact, the pressure causes the annular plate 205c to move downward. Simultaneously, one end of the limiting block 205d is slidably connected within the straight groove 205e and the arc groove 205f. Due to the deflection force of the arc groove 205f, the auxiliary head 204a rotates. When the connector 201b and the auxiliary head 204a are in contact, one end of the limiting block 205d moves to the end of the arc groove 205f. At this time, the arc hole 205h and the circular hole 205i are on the same plane. Then, the bolt is screwed into the arc hole 205h and the circular hole 205i to ensure the stability of the connection between the connector 201b and the auxiliary head 204a. This ensures the quick connection between the urine collection liner 101 and the squat toilet 400.

[0038] Example 3, referring to Figures 1 to 9 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a waterless toilet for urination and a water-flushing toilet for defecation, including the waterless toilet for urination and a water-flushing toilet for defecation in the above embodiment. A positioning head 206a is symmetrically fixedly connected to one end of the plug. A round protrusion 206b is integrally formed on one end of the positioning head 206a. An arc notch 206c is symmetrically provided inside the annular edge 203b. A positioning protrusion 206d is fixedly connected to one end of the inner wall of the arc notch 206c. The round protrusion 206b is slidably connected in the arc notch 206c and engages with the positioning protrusion 206d. A sealing ring 206e is provided on the inner wall of the annular edge 203b. The sealing ring 206e is disposed between the plug and the annular edge 203b. By further defining the structure of the connector, a positioning head 206a is integrally formed on the outer wall of the connector. When the connector 201b and the auxiliary head 204a are connected, their round protrusion 206b and positioning protrusion 206d engage. At the same time, the round protrusion 206b is made of elastic material to ensure secondary positioning of the connector 201b and the auxiliary head 204a. The positioning head 206a is inverted L-shaped. Since the back of the positioning head 206a is arc-shaped, it ensures the stability of its movement. This ensures that the round protrusion 206b and the positioning head 206a are stably engaged, improving convenience.

[0039] The rest of the structure is the same as in Example 2.

[0040] As the connector moves downwards and the connector 201b and auxiliary head 204a come into contact, the round protrusion 206b on the positioning head 206a moves into the arc notch 206c. At the same time, the deflection force of the arc groove 205f drives the auxiliary head 204a to rotate. This causes the round protrusion 206b to slide in the arc notch 206c and engage with the positioning protrusion 206d, ensuring the stability of the connection between the connector 201b and the auxiliary head 204a. Furthermore, the sealing ring 206e on the inner wall of the annular edge 203b ensures the sealing of the connector and the annular edge 203b.
