Description

Technical Field

[0001] The present application relates to a connecting accessory, in particular to a connecting accessory for connecting a main flush pipe and a ceramic body of a toilet. The present application also relates to a main flush pipe assembly and a toilet. Background Art

[0002] The main structure of a toilet is usually made of ceramic, which has a large shrinkage rate. Therefore, if the water pipes are made of ceramic itself, it may cause precision deviations in the pipe aperture during production, affecting the final water supply effect and may cause some additional problems, such as noise.

[0003] The main flush line, as the toilet's primary flushing system, is subject to stricter requirements. Currently, the main flush line is manufactured as a separate pipe from the ceramic body, such as a main flush hose. This structure requires connecting fittings between the main flush line and the ceramic body, which impose various technical requirements, such as easy connection and reliable sealing structure. Summary of the Invention

[0004] In response to the above problems, the present application discloses a main flush pipe connecting accessory for a toilet to overcome the above problems or at least partially solve the above problems.

[0005] The present application also discloses a main flush pipe assembly having the above main flush pipe connection fitting, and

[0006] The present application also discloses a toilet having the main flush pipe assembly.

[0007] In order to achieve the above objectives, this application adopts the following technical solutions:

[0008] The present application provides a main flush pipe connecting accessory for a toilet. Through the main flush pipe connecting accessory, the main flush pipe can be connected to the assembly hole on the ceramic body of the toilet. The main flush pipe connecting accessory includes: a connecting pipe body extending along an extension direction, and a connecting part arranged on the outer surface of the connecting pipe body. The connecting part can be assembled on the ceramic body, and along the extension direction, the connecting pipe body is divided into: an outlet pipe located on one side of the connecting part that can extend into the assembly hole, and a water inlet pipe located on the other side of the connecting part.

[0009] The toilet's main flush pipe connection fitting connects the outlet pipe to the mounting hole of the ceramic body, and then connects to the main flush pipe via the water inlet pipe on the other side of the connection. This simple connection structure facilitates the connection between the main flush pipe and the ceramic body, solves the adaptation problem of direct connection between the main flush pipe and the ceramic body, and reduces the requirements for the machining precision of the ceramic body.

[0010] In an exemplary embodiment of the main flush pipe connection accessory of a toilet, the outer surface of the water outlet pipe has a first sealing section on which a sealing ring can be mounted, and the first sealing section can seal with the assembly hole at the opening position.

[0011] In an exemplary embodiment of the main flush pipe connection fitting of the toilet, the outer surface of the water outlet pipe further has a second sealing section capable of being fitted with a sealing ring, and the second sealing section can be sealed with the assembly hole at an in-hole position.

[0012] The first sealing section and the second sealing section on the outer surface of the water outlet pipe can achieve double sealing with the assembly hole, and the two sealing positions of the first sealing section and the second sealing section help to a certain extent to assemble and position the water outlet pipe in the assembly hole, making the overall structure more firm and stable.

[0013] In one exemplary embodiment of a toilet main flush pipe connection fitting, a protruding abutment is provided on the outer surface of the outlet pipe between the first and second sealing sections. The abutment is configured to abut against a sealing ring mounted within the second sealing section along its extension direction. This abutment prevents the second sealing ring from shifting out of its sealing position due to compression, thereby ensuring a secure seal.

[0014] In one exemplary embodiment of a toilet main flush pipe connection fitting, the outer diameter of the first sealing section of the outlet pipe is larger than that of the second sealing section. The abutment portion includes several ribs spaced around the outer surface of the outlet pipe. Each rib is arranged along its extension direction, and the highest radial position of each rib is less than or equal to the outer diameter of the first sealing section and larger than the outer diameter of the second sealing section. This structure facilitates the fitting of the first sealing ring onto the first sealing section, ensuring that the abutment portion abuts and positions the second sealing ring. The rib structure also facilitates demolding during production, facilitating manufacturing.

[0015] In an exemplary embodiment of a toilet main flush pipe connection accessory, the connecting portion has a connection surface capable of contacting and connecting with the ceramic body. This connection method of the connecting portion and the ceramic body can reduce the requirements for the processing precision of the ceramic body, making the entire assembly process more convenient and reliable.

[0016] In an exemplary embodiment of a toilet main flush pipe connection accessory, a limiting groove capable of accommodating a sealing ring is formed on the connection surface. The limiting groove helps to position the sealing ring, and the groove depth of the limiting groove helps to limit the amount of compression of the sealing ring when squeezed.

[0017] The present application also provides a main flush pipe assembly, which includes a main flush pipe and the above-mentioned main flush pipe connecting accessory, wherein the water inlet pipe of the main flush pipe connecting accessory can be connected to the main flush pipe.

[0018] In an exemplary embodiment of the main flush pipe assembly, the flush pipe assembly further includes a clamp capable of connecting the main flush pipe to the water inlet pipe.

[0019] The present application also provides a toilet comprising a ceramic body and the above-mentioned main flush pipe assembly, wherein the ceramic body is formed with a main flush pipe connecting portion, and the main flush pipe connecting portion is provided with an assembly hole, wherein the water outlet pipe of the main flush pipe connecting accessory can extend into the assembly hole.

[0020] In the above toilet structure, the main flush pipe connecting accessories are used to complete the connection between the main flush pipe and the ceramic body. The assembly process is convenient and reliable, and the requirements for the processing accuracy of the ceramic body can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] To make the purpose, technical solutions, and advantages of this application more clear, the following will provide a clear and complete description of the technical solutions of this application in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] In this document, “illustrative” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “illustrative” should not be interpreted as a more preferred or more advantageous technical solution.

[0046] To simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled.

[0047] Herein, “horizontal”, “vertical”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in production or use.

[0048] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0049] Figure 1 A schematic diagram of the exploded three-dimensional structure used to illustrate the assembly state of the main flush pipe connection accessories of the toilet. Figure 1 As shown, Figure 1 The structure drawn by the solid line is the main flush pipe connecting accessory 10 of the toilet. The main flush pipe connecting accessory 10 is used to assemble the main flush pipe 20 and the ceramic body 30 of the toilet into one body. To achieve assembly, an assembly hole 32 is provided on the ceramic body 30.

[0050] Figure 2 To illustrate Figure 1 The three-dimensional structural diagram of the main flush pipe connection accessories of the toilet is shown in FIG. Figure 1 and Figure 2 As shown, the main flush pipe connection fitting 10 includes a connection pipe body 12 and a connection portion 14 provided on the outer surface of the connection pipe body 12. The connection pipe body 12 extends along the extension direction X indicated by the arrow in the figure, and the connection portion 14 can be assembled with the ceramic body 30 to connect the main flush pipe connection fitting 10 to the ceramic body 30.

[0051] And along the extension direction X, the connecting portion 14 divides the connecting pipe body 12 into two parts: one part is the water outlet pipe 124 located on one side of the connecting portion 14 (the right side in the figure), and the other part is the water inlet pipe 122 located on the other side of the connecting portion 14 (the left side in the figure).

[0052] The main flush pipe connecting accessory 10 of the above-mentioned toilet can be connected to the ceramic body 30 through the connecting part 14, and at the same time, the water outlet pipe 124 in the connecting pipe body 12 is extended into the assembly hole 32 of the ceramic body to achieve connection with the assembly hole 32. The connection structure is simple and uses the main flush pipe connecting accessory 10 as the intermediate connecting accessory to solve the adaptation problem of direct connection between the main flush pipe and the ceramic body, and there is no need to consider the requirements for the processing accuracy of the ceramic body during direct connection.

[0053] Among them, along the extension direction X, the outer surface of the water outlet pipe 124 also has two sealing sections that can be respectively covered with sealing rings, namely the first sealing section 125 and the second sealing section 126, see Figure 2 , see also Figure 3 , Figure 3 To illustrate Figure 1 The diagram shown is a cross-sectional structural diagram of the main flush pipe connection accessories of the toilet after assembly.

[0054] The sealing ring that can be sleeved on the first sealing section 125 can be correspondingly referred to as the first sealing ring 50 (see Figure 1 and Figure 3 ), which is usually made of a relatively hard sealing material. After the first sealing ring 50 is installed on the first sealing section 125, it can be sealed with the assembly hole 32 at the opening position of the assembly hole 32. The sealing ring that can be installed on the second sealing section 126 can be correspondingly called the second sealing ring 60 (see Figure 1 ), compared with the first sealing ring, the second sealing ring 60 is usually made of a relatively soft sealing material. After the second sealing ring 60 is sleeved, the second sealing section 126 can be sealed with the assembly hole 32 at the hole position of the assembly hole 32.

[0055] The toilet main flush pipe connection fitting 10 utilizes the first sealing section 125 and the second sealing section 126 on the outer surface of the outlet pipe 124 to achieve a double seal with the assembly hole 32, thereby improving the sealing effect. Of course, those skilled in the art will appreciate that in some cases, only one sealing section may be provided on the outer surface of the outlet pipe to provide a single seal.

[0056] exist Figures 1 to 3 In the illustrated embodiment, the first sealing section 125 of the water outlet pipe 124 is connected to the connecting portion 14, i.e., the first sealing section 125 is adjacent to the connecting portion 14. During the connection process between the connecting portion 14 and the ceramic body 30, the connecting portion 14 can help compress the first sealing ring 50 mounted on the first sealing section 125 to more effectively seal the opening of the assembly hole 32. The second sealing section 126 of the water outlet pipe 124 constitutes the water outlet end of the water outlet pipe 124 to achieve a seal at the end of the water outlet pipe 124. It can be seen that the two sealing positions of the first sealing section 125 and the second sealing section 126 also help to a certain extent to facilitate the assembly and positioning of the water outlet pipe 124 within the assembly hole 32, making the overall structure more secure and stable.

[0057] exist Figures 1 to 3 In the described embodiment, the water outlet pipe 124 further has a protruding abutment portion 127 on its outer surface between the first sealing section 125 and the second sealing section 126. The abutment portion 127 is capable of abutting against the second sealing ring 60 disposed within the second sealing section 126 along the extension direction X. As the water outlet pipe 124 extends into the assembly hole 32, the abutment portion 127 prevents the second sealing ring 60 from shifting from its sealing position due to compression, thereby ensuring a good sealing effect.

[0058] In the embodiment shown in the figure, the outer diameter of the first sealing section 125 of the outlet pipe 124 is larger than the outer diameter of the second sealing section 126, and the abutment portion 127 includes a plurality of ribs arranged at intervals around the outer surface of the outlet pipe 124, each rib is arranged along the extension direction X, and the highest position of each rib in the radial direction is less than or equal to the outer diameter of the first sealing section 125 and larger than the outer diameter of the second sealing section 126. For details, see Figure 3 Ensuring that the highest radial position of each rib is less than or equal to the outer diameter of the first sealing segment 125 facilitates the fitting of the first sealing ring 50 within the first sealing segment 125. Ensuring that the highest radial position of each rib is greater than the outer diameter of the second sealing segment 126 ensures that the abutment portion 127 can abut and position the second sealing ring 60. Furthermore, the design of the rib structure along the extension direction X facilitates demolding during production, facilitating manufacturing.

[0059] exist Figures 1 to 3In the embodiment shown, the connecting portion 14 has a connecting surface (not shown) that can contact and connect to the ceramic body. The structure in the figure is specifically as follows: the connecting portion 14 is a connecting plate arranged perpendicular to the extension direction X, and the connecting plate is provided with a pair of connecting holes 142 arranged along the extension direction. The connection relationship between the connecting surface of the connecting portion 14 and the ceramic body 30 is achieved by using the connecting holes 142. It can be seen that by connecting the connecting surface of the connecting portion 14 to the ceramic body 20, the requirements for the processing accuracy of the ceramic body can be reduced, the adaptability is higher, and the entire assembly process is more convenient and reliable. Of course, depending on the design requirements, the specific structure of the connecting portion 14 is not limited to that shown in the figure.

[0060] Figure 3 In the illustrated embodiment, the connection surface of the connection portion 14 is further formed with a limiting groove 144 capable of accommodating the first sealing ring 50. The limiting groove 144 helps to position the first sealing ring 50, and the groove depth of the limiting groove 144 helps to limit the compression amount of the first sealing ring 50 when squeezed.

[0061] This application also provides a main flush pipe assembly, see Figure 1 All structures on the left side of the main flush pipe connection fitting 10, such as Figure 1 As shown, the main flush pipe assembly includes a main flush pipe 20 and the above-mentioned main flush pipe connecting accessory 10, wherein the main flush pipe 20 can be connected to the water inlet pipe 122 of the main flush pipe connecting accessory 10 (see Figure 2 and Figure 3 The other structures of the main flush pipe connecting fitting 10 have been described above and will not be repeated here.

[0062] Figure 1 In the illustrated embodiment, the flush pipe assembly further includes a clamp 70 capable of connecting the main flush pipe 20 to the water inlet pipe 122. Of course, depending on design requirements, the assembly connection between the main flush pipe 20 and the water inlet pipe 122 may also be achieved through other structures.

[0063] This application also provides a toilet, also known as a toilet, see Figure 1 , which includes a ceramic body 30, the above-mentioned main flushing pipe assembly (such as Figure 1 All structures on the left side of the main flush pipe connection accessory 10 shown).

[0064] The ceramic body 30 is formed with a main flush pipe connection portion 31, and the main flush pipe connection portion 31 is provided with an assembly hole 32. The outlet pipe 124 of the main flush pipe connection accessory 10 in the main flush pipe assembly can extend into the assembly hole 32.

[0065] In addition, the first sealing ring 50 can be sleeved on the first sealing section 125 of the water outlet pipe 124 (see Figure 2 and Figure 3) to seal the outlet pipe 124 at the opening position of the assembly hole 32. The second sealing ring 60 can be sleeved on the second sealing section 126 of the outlet pipe 124 (see Figure 2 and Figure 3 ) to seal the water outlet pipe 124 in the hole position of the assembly hole 32.

[0066] The three-dimensional structure of the toilet after assembly can be seen in Figure 4 In the above toilet structure, the main flush pipe connecting fitting 10 is used to complete the connection between the main flush pipe 20 and the ceramic body 30, which makes the assembly process convenient and reliable and reduces the requirements for the processing accuracy of the ceramic body.

Based on the above teachings of the present application, those skilled in the art may make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above description is only a better explanation of the purpose of the present application, and the scope of protection of the present application shall be based on the scope of protection of the claims.
