DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0048] The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0049] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] like Figure 1-6 As shown, the first embodiment of the present application provides a connector 1 (hereinafter referred to as connector 1) for connecting a seat pool 100 and a base 200, which includes: a first part 2 facing the seat pool 100 and a second part 3 facing the base 200 in a connected state; the first part 2 and the second part 3 are arranged roughly oppositely, for example, the first part 2 is located at the upper part of the connector, and the second part 3 is located at the lower part of the connector.

[0051] like Figure 3 and Figure 4 As shown, the middle part of the connector 1 is formed with a sewage hole 4 that penetrates the first part 2 and the second part 3 of the connector 1, so that the sewage in the seat pool 100 can be discharged downward through the hole. The base 200 also has a sewage channel, which can connect the sewage to the outside through a sewage pipe (not shown in the figure). The base 200 in the present application can be made by blow molding process, and mainly plays a supporting role, supporting the seat pool 100 and other components as well as supporting the user when entering the toilet.

[0052] like Figure 2 and Figure 3 As shown, a first groove 41 capable of accommodating a first sealing ring 5 is provided on the side of the sewage hole 4 on the connector 1 facing the seat pool 100 , so as to achieve sealing between the connector 1 and the seat pool 100 .

[0053] The connector 1 is provided with a plurality of first mounting holes 6 and second mounting holes 7 around the sewage hole 4, respectively penetrating the first part 2 and the second part 3 of the connector 1. The first mounting holes 6 are configured to be used for mounting the connector 1 on the seat pool 100; for example, bolts can be inserted from the side of the second part 3 to the side of the first part 2 to fix the connector 1 on the seat pool 100, and the first sealing ring 5 between the two is also compressed. The second mounting holes 7 are configured to be used for mounting the connector 1 on the base 200; for example, nuts can be pre-embedded on the side of the first part 2, and after the seat pool 100 and the connector 1 are installed, bolts are inserted upward from the bottom of the base 200 to cooperate with the pre-embedded nuts to fix the base 200 and the connector 1.

[0054] like Figure 2-4 As shown, the seat pool 100 is made of ceramic material, and a recessed embedding groove 101 is provided at the bottom thereof. The entire connector 1 can be made of plastic material, which is manufactured by one-step molding and has a certain rigidity and strength. The first part 2 of the connector is provided with a raised embedding portion 8 that matches the embedding groove 101; by inserting the embedding portion 8 into the embedding groove 101, the seat pool 100 and the connector 1 can be aligned.

[0055] Furthermore, in order to solve the problem of low hole precision and difficulty in matching of the ceramic seat pool 100, a plurality of fins 9 that are spaced and can be squeezed and deformed are arranged around the embedding portion 8, such as elastic plastic sheets. These fins 9 can be configured to be evenly spaced along the outer wall of the embedding portion 8; the extension direction of each fin 9 is parallel to the connection direction X between the seat pool 100 and the connector 1, for example, Figure 3 The bottom of each fin 9 is fixed on the first part 2. The end of each fin 9 close to the seat pool 100 is provided with a chamfer to guide the embedding portion 8 and the fin 9 to be inserted into the embedding groove 101. When the seat pool 100 and the connector 1 are connected, the embedding portion 8 and its fin 9 are interference fit in the embedding groove 101 at the bottom of the seat pool 100; in this process, at least part of the fin 9 will be squeezed, deformed, and may be partially damaged, so as to be completely filled in the embedding groove 101; since there may be machining accuracy errors in the ceramic opening, the fin 9 will fill the operation error, thereby fixing the ceramic seat pool, and bearing the horizontal force to prevent the seat pool from moving horizontally, with high stability.

[0056] like Figure 2-4As shown, the connector 1 is provided with a water inlet hole 10 for a water inlet pipe 11 to pass through so as to introduce water from the outside. In a specific embodiment, the first part 2 of the connector is provided with a bracket 12 extending along the connection direction X toward the seat pool 100 near the edge of the connector; the water inlet hole 10 passes through the bracket 12. The bracket 12 is also formed with a mounting groove 13, and the water inlet pipe 11 is provided with a sheet-shaped structure 14. By inserting the sheet-shaped structure 14 into the mounting groove 13, the water inlet pipe 11 is fixed to the bracket 12. Furthermore, the mounting groove 13 includes a first groove 131 close to one side of the seat pool, raised limiting portions 132 located on both sides of the bracket 12, and an insertion portion 133 close to one side of the base; the sheet-type structure 14 can be inserted into the mounting groove 13 from top to bottom from the insertion portion 133, so that the top and both sides of the sheet-type structure 14 are respectively limited by the first groove 131 and the limiting portion 132, and the insertion portion 133 at the bottom is limited by the base after being combined with the base 200, thereby fixing the water pipe 11.

[0057] like Figure 3 As shown, a plurality of fins may also be provided at the root of the bracket 12 adjacent to the first part 2 of the connector. These fins respectively connect the bracket 12 and the first part 2 of the connector, which can enhance the stability of the bracket 12 on the one hand, and can also abut against the opening at the tail of the seat pool on the other hand, playing a role of interference fit similar to the fins of the embedded part.

[0058] The connector 1 is also provided with an upper water pipe hole 15 and a lower water pipe hole 16 which are adjacent and respectively penetrate the first part 2 and the second part 3 of the connector, so as to pass the upper water pipe and the lower water pipe (not shown in the figure) respectively. Figure 3 and Figure 4 As shown, the upper water pipe hole 15 and the lower water pipe hole 16 can be both located in the space surrounded by the embedded part 8, so that the embedded part 8 is elliptical with a hollow structure. A spacer 17 is formed between the upper water pipe hole 15 and the lower water pipe hole 16, and the spacer 17 can support the corresponding upper water pipe and lower water pipe.

[0059] The seat pool 100 has a hollow structure in which water can be stored. Figure 5As shown, the base 200 has a foot-operated water valve 202, which can be opened or closed by stepping on it from the outside. The water valve 202 is connected to a water inlet pipe and a water outlet pipe respectively, the water inlet pipe is connected to the hollow structure of the seat pool 100, and the water outlet pipe is connected to the water spray port of the seat pool; this is known in the prior art, for example, CN103147499A discloses these technical solutions. In this embodiment, water from the outside can enter the hollow structure of the seat pool 100 upward after entering from the water inlet pipe 11; when the water valve 202 is opened, since the downpipe (equivalent to the water inlet pipe) is connected to the hollow structure of the seat pool 100, the stored water can be guided to the water valve 202 of the base 200, and the opened water valve 202 guides the water to the upper water pipe (equivalent to the water outlet pipe), and then washes the seat pool through the water spray port of the seat pool 100. The "upper" and "lower" here refer to the reference Figure 1 and Figure 2 Description of the direction of water flow.

[0060] like Figure 4 As shown, the second part 3 of the connector extends along the connection direction X toward the base 200 to form a support 18, and the support 18 can be extended with the spacer 17 as the root, so that the support 18 is located between the upper water pipe hole 15 and the lower water pipe hole d. Both sides of the support 18 can form reinforcing ribs extending to the second part 3 to increase its strength. The support 18 is configured to press the water valve 202 in the base 200, as shown in FIG. Figure 5 As shown. Since the water valve is subjected to force during the startup process, the support 18 can be used to fix the water valve 202 and transmit the force.

[0061] like Figure 4 and Figure 5 As shown, the second part 3 of the connector is provided with a buckle 19, which can be snapped into the snap-fit ​​groove 201 of the base 200. The buckle 19 has an extension portion 191 that can be squeezed and deformed, for example, it is made of plastic and has elasticity. The free end of the extension portion 191 is provided with a second protrusion 192 to snap into the snap-fit ​​groove 201; the side of the second protrusion 192 close to the base 200 is an inclined surface 193 to guide the snap-fit. In addition, a reinforcing rib 194 can be provided between the extension portion 191 and the second part 3 to enhance the strength of the buckle 19. Through the connection between the buckle 19 and the snap-fit ​​groove 201, it is possible to form a counteracting force generated by the downward pressure of the user on the opposite side during use.

[0062] like Figure 2 and Figure 4 As shown, the sewage hole 4 extends toward the base 200 along the connection direction X and forms an annular step 42 at its free end, which can accommodate a second sealing ring 20 with an "L"-shaped cross-section and adapted (matched) to the outer wall of the step 42, so as to achieve sealing between the connector 1 and the base 200.

[0063] Furthermore, in order to better fix the second sealing ring 20 and prevent it from falling, as Figure 4 and Figure 6 As shown, the outer wall of the sewage hole 4 is circumferentially provided with a plurality of first protrusions 43; the locking ring 21 for locking the sealing ring 20 has a plurality of openings 211 on the side close to the connector 1, and a part of each opening 211 is blocked, thereby forming an entrance port 212 and a limit port 213 that are interconnected; the inner diameter of the locking ring 21 away from the connector 1 is smaller than the outer diameter of the second sealing ring 20; the first protrusion 43 is configured to be able to enter the entrance port 212 of the locking ring 21, and enter the limit port 213 of the locking ring 21 by rotation, so that the second sealing ring 20 is locked between the first protrusion 43 and the locking ring 21 and is not easy to fall off.

[0064] In this embodiment, the seal between the connector 1 and the base 200 is mainly achieved by the second sealing ring 20 , and the stable connection between the two is mainly achieved by the buckle 19 .

[0065] like Figure 3 and Figure 4 As shown, the first part 2 and the second part 3 of the connector may also form a plurality of recessed parts 22, at least a portion of which is provided with mesh reinforcing ribs 23, thereby reducing the weight of the connector 1 while increasing its supporting strength.

[0066] The second embodiment of the present application provides a portable toilet, such as Figure 1 and Figure 2 As shown, it includes the connector 1 for connecting the seat pool and the base as described in the first embodiment above.

[0067] like Figure 7-11 As shown, the third embodiment of the present application provides another connector 1 for connecting the seat pool 100 and the base 200, which includes: a first part 2 facing the seat pool 100 and a second part 3 facing the base 200 in the connected state; the first part 2 and the second part 3 are arranged roughly oppositely.

[0068] like Fig. 9 and Fig.10 As shown, a sewage hole 4 is formed in the middle of the connector 1, which penetrates the first part 2 and the second part 3 of the connector 1, so that the sewage in the seat pool 100 can be discharged downward through the hole. The base 200 mainly plays a supporting role, and a mobile sewage tank (not shown in the figure) that can be pulled out from one side can be arranged therein to accommodate sewage.

[0069] like Figure 8 and Fig. 9As shown, a first groove 41 capable of accommodating a first sealing ring 5 is provided on the side of the sewage hole 4 on the connector 1 facing the seat pool 100 , so as to achieve sealing between the connector 1 and the seat pool 100 .

[0070] The connector 1 is provided with a plurality of first mounting holes 6 around the sewage hole 4, respectively penetrating the first portion 2 and the second portion 3 of the connector 1. The first mounting holes 6 are configured to be used for mounting the connector 1 on the seat pool 100; for example, bolts can be inserted upward from the bottom to fix the connector 1 on the seat pool 100, and the first sealing ring 5 between the two is also compressed.

[0071] The seat pool 100 is made of ceramic material, and a concave embedding groove 101 is provided at the bottom thereof. The connector 1 can be made of plastic material. A convex embedding portion 8 is provided on the first portion 2 of the connector to match the embedding groove 101; by inserting the embedding portion 8 into the embedding groove 101, the seat pool 100 and the connector 1 can be matched and aligned.

[0072] Furthermore, in order to solve the problem of low hole opening accuracy and difficulty in matching of the ceramic seat pool 100, a plurality of fins 9 that are spaced and can be squeezed and deformed are arranged around the embedded portion 8, for example, elastic plastic sheets. These fins 9 can be configured to be evenly spaced along the outer wall of the embedded portion 8; the extension direction of each fin 9 is parallel to the connection direction X between the seat pool 100 and the connector 1. The bottom of each fin 9 is fixed on the first part 2. A chamfer is provided at one end of each fin 9 close to the seat pool 100 to guide the embedded portion 8 and the fin 9 to be inserted into the embedded groove 101. When the seat pool 100 and the connector 1 are connected, the embedded portion 8 and its fins 9 are interference fit in the embedded groove 101 at the bottom of the seat pool 100; in this process, at least part of the fins 9 will be squeezed and deformed, and may also be partially damaged, so as to be completely filled in the embedded groove 101; its effect is the same as the first embodiment.

[0073] The seat pool 100 has a water spray port; the base 200 can store sewage; this is known in the prior art, for example, CN103147499A discloses these technical solutions. In this embodiment, water from the outside is directly connected to the water spray port of the seat pool 100, washes the seat pool 100, and flows into the sewage tank in the base 200 through the sewage hole 4, and no water supply pipe and water supply pipe are provided as in the first embodiment.

[0074] like Fig.10As shown, the second part 3 of the connector is evenly and spacedly provided with a plurality of buckles 19 around the sewage hole 4; each buckle 19 is located on the circumference of the same circle, and can be snapped into the annular snap-fit ​​groove (not shown in the figure) of the base 200 to be in a rotatable state. Each buckle 19 has an extension portion 191 that can be squeezed and deformed, for example, made of plastic and elastic. The free end of the extension portion 191 is provided with a second protrusion 192 to snap into the snap-fit ​​groove; the side of the second protrusion 192 close to the base 200 is an inclined surface 193 to guide the snap-fit. Through the connection between the buckle 19 and the snap-fit ​​groove, a rotatable track structure is formed, so that the connector 1 can rotate upward after being combined with the ceramic seat pool 100; in addition, it can also form a counteracting gravity generated by the downward sitting pressure of the user during use.

[0075] like Fig.10 As shown, the sewage hole 4 extends toward the base 200 along the connection direction X and forms an annular step 42 at its free end, which can accommodate a second sealing ring 20 with an "L"-shaped cross-section and adapted (matched) to the outer wall of the step 42, so as to achieve sealing between the connector 1 and the base 200.

[0076] In order to better fix the second sealing ring 20 and prevent it from falling, Fig.10 and Fig.11 As shown, the outer wall of the sewage hole 4 can be provided with an external thread; the locking ring 21 used to lock the sealing ring 20 is provided with an internal thread on the side close to the connector 1, and the inner diameter of the locking ring 21 on the side away from the connector 1 is slightly smaller than the outer diameter of the second sealing ring 20; the rotational cooperation of the external thread of the sewage hole 4 and the internal thread of the locking ring 21 can make the second sealing ring 20 be locked between the sewage hole 4 and the locking ring 21, and it is not easy to fall off.

[0077] In this embodiment, the seal between the connector 1 and the base 200 is mainly achieved by the second sealing ring 20 , and the stable connection between the two is mainly achieved by the buckle 19 .

[0078] The first part 2 and the second part 3 of the connector may form a plurality of recessed parts 22 to reduce the weight of the connector 1 .

[0079] By comparison, it can be seen that the third embodiment cancels the upper water pipe hole 15 and the lower water pipe hole d compared to the first embodiment. Since water is directly inletted, no water valve is required, so the connector of the third embodiment does not have the upper water pipe hole and the lower water pipe hole; and also cancels the second mounting hole 7 and other structures. However, it is understandable that some technical solutions in the two embodiments can be mutually referenced according to actual conditions, such as the setting of the locking ring, the setting of the mesh reinforcement ribs, etc.

[0080] A fourth embodiment of the present application provides a portable toilet, such as Figure 7 , Figure 8 , Fig.12 and Fig.13 As shown, it includes the connector 1 for connecting the seat pool and the base as described in the third embodiment above.

[0081] Furthermore, a clean water tank 300 for storing clean water is also disposed on the base 200 , which can directly provide clean water for the seat pool 100 .

[0082] The upper surface of the base 200 has one or more second recessed grooves 203 (such as Figure 7 The clean water tank 300 has a third protrusion 301 extending toward the base 200 (as shown); Fig.13 The third protrusion 301 can be embedded in the second groove 203 of the base 200 to fix the clean water tank 300 on the base 200.

[0083] In some embodiments, Fig.12 and Fig.13 As shown, the clean water tank 300 also has a concave arc portion 302; the arc portion 302 is adjacent to the rear of the seat pool 100, limiting the excessive rotation of the seat pool 100. When in use, the seat pool can be rotated approximately 90° to the left and right, but cannot be fully rotated 360°.

[0084] In addition, the clean water tank 300 may also be provided with a water inlet, a flushing button and other components, which is a technical solution well known to those skilled in the art.

[0085] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0086] The above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution requested for protection in the present application.
