Abstract
Description
Technical Field
[0001] This utility model relates to the field of bathroom products technology, and in particular to an easy-to-install water trap device for a split squat toilet. Background Technology
[0002] There are many problems with the installation of water traps in existing split-type squat toilets:
[0003] First, the pipe diameter compatibility is poor. The diameter of the common water trap connector does not match the PVC sewage pipe. The outer diameter of the water trap connector sold on the market is 75mm, while the inner diameter of the PVC sewage pipe is 110mm. When the water trap and the PVC sewage pipe are connected by insertion, there is a large gap, which makes it impossible to connect tightly, greatly affecting the convenience of installation and sealing.
[0004] Secondly, the installation is difficult. Due to the mismatch in pipe diameter, construction workers have difficulty operating normally during installation and have to resort to filling gaps, such as using cement, tape, and other non-standard methods. This not only increases the difficulty and time cost of construction, but also makes it difficult to guarantee the installation quality.
[0005] Furthermore, the durability is poor. The non-standard installation method and the filling materials used are susceptible to temperature changes, moisture erosion, pipe vibration and other factors over time, which can quickly cause them to loosen, age and degrade, leading to failure of the seal at the joint.
[0006] Finally, there are significant hygiene concerns. The connection between the water trap and the PVC drain pipe is prone to leakage, which can pollute the surrounding environment. At the same time, it can cause odors, breed bacteria and mosquitoes, seriously affecting indoor air quality and living hygiene, and posing a threat to residents' health.
[0007] Therefore, this utility model is proposed. Utility Model Content
[0008] The purpose of this utility model is to provide an easy-to-install water trap device for a split squat toilet. This device can solve the problem of mismatch between the water trap and the sewage pipe diameter. It is easy to install and operate, and ensures a firm connection between the water trap and the sewage pipe, thus guaranteeing the stable operation of the drainage system.
[0009] This utility model provides an easy-to-install water trap device for a split squat toilet, including a water trap with an inlet and an outlet at both ends. A connecting pipe is provided at the outlet, and the connecting pipe includes a first pipe body and a second pipe body. The first pipe body is connected to the outlet, and the inner diameter of the second pipe body is larger than that of the first pipe body. The first pipe body and the second pipe body are connected by a reducing pipe.
[0010] Furthermore, the water trap has a horizontal bottom.
[0011] Furthermore, the first tube body, the second tube body, and the reducer are integrally formed.
[0012] Furthermore, the reducer is an eccentric reducer.
[0013] Furthermore, the bottoms of the first pipe body, the second pipe body, and the reducer are kept at the same horizontal position, and the pipe axes of the first pipe body, the second pipe body, and the reducer are not on the same straight line but are parallel to each other.
[0014] Furthermore, the inner diameter of the first pipe is consistent with the outer diameter of the outlet of the water trap.
[0015] Furthermore, the outer diameter of the second pipe is consistent with the inner diameter of the sewage pipe to be connected.
[0016] Furthermore, the outer wall of the water outlet of the water trap is provided with several annular grooves.
[0017] Furthermore, the water trap is made of ceramic, and the connecting pipe is made of plastic.
[0018] Furthermore, the connecting pipe and the water trap are fixed by welding, and the annular groove is located inside the first pipe body.
[0019] In summary, this utility model has the following advantages:
[0020] The device provided by this utility model addresses the problem of mismatched diameters between the water trap and the drain pipe in traditional split-type squat toilets. It innovatively adopts a variable diameter connecting pipe to achieve accurate connection between the water trap and the drain pipe, fundamentally solving the installation and sealing problems caused by pipe diameter differences. This ensures stable operation of the drainage system, eliminates various hidden dangers caused by improper connection, and creates a safe and comfortable living environment. Furthermore, the installation process is simple: just connect the water trap to the drain outlet of the squat toilet, and then connect the connecting pipe to the drain pipe. The connection is strong and secure after installation. Attached Figure Description

[0029] Example
[0030] A split-type squat toilet with an easy-to-install water trap device, such as Figure 1 and Figure 2 As shown, the device includes a water trap 1, with an inlet 101 and an outlet 102 at each end. A connecting pipe 2 is located at the outlet 102. The connecting pipe 2 includes a first pipe body 201 and a second pipe body 203. The first pipe body 201 connects to the outlet 102, and the inner diameter of the second pipe body 203 is larger than the inner diameter of the first pipe body 201. The first pipe body 201 and the second pipe body 203 are connected by a reducer 202. The inner diameter of the first pipe body 201 matches the outer diameter of the outlet 102 of the water trap 1, facilitating a tight connection between the connecting pipe 2 and the water trap 1. The outer diameter of the second pipe body 203 matches the inner diameter of the drain pipe, also facilitating a tight connection between the connecting pipe 2 and the drain pipe. For example, if the outer diameter of the outlet 102 of the water trap 1 is 75mm and the inner diameter of the drain pipe is 110mm, then the inner diameter of the first pipe body 201 is 75mm, and the outer diameter of the second pipe body 203 is 110mm.
[0031] In this embodiment, the water trap 1 is a conventional water trap for a split-type squat toilet. The water inlet 101 of the water trap 1 is connected to the drain outlet of the squat toilet, and the water trap 1 has a horizontal base 103. The water trap 1 is made of plastic or ceramic. The horizontal base 103 of the water trap 1 allows for the placement of a pad at the bottom of the water trap 1 during installation, depending on the location of the drain pipe, to increase stability. A sealing ring can be installed at the water inlet 101 of the water trap 1 to increase the sealing performance of the connection with the squat toilet.
[0032] like Figure 3 As shown, the water outlet 102 of the trap 1 has two annular grooves 104 on its outer wall. The first pipe body 201 encloses the two annular grooves 104, placing them inside the first pipe body 201. The annular grooves 104 on the outer wall of the trap 1 increase the stability of the connection with the connecting pipe 2. When the connecting pipe 2 is made of PVC and the trap 1 is made of ceramic, a hot-melt expansion inlay technique can be used. Utilizing the principle of thermal expansion and contraction, the first pipe body 201 is heated to expand its inner diameter, then combined with the trap 1. After the first pipe body 201 connects with the trap 1, it contracts to form a seal, and the joint is sealed with glue. Due to the annular grooves at the water outlet of the trap 1, its outer surface has a concave-convex structure. After the first pipe body 201 contracts, it fits tightly against the outside of the trap 1, forming a mechanical interlocking interface, resulting in a tight physical fit and effectively enhancing the pull-out resistance of the connection.
[0033] The first pipe body 201, the second pipe body 203, and the reducer 202 of the connecting pipe 2 are integrally molded structures. The reducer 202 is an eccentric reducer. The bottoms of the first pipe body 201, the second pipe body 203, and the reducer 202 are kept at the same horizontal position. The pipe axes of the first pipe body 201, the second pipe body 203, and the reducer 202 are not collinear but parallel to each other. The connecting pipe 2 is made of plastic, and can be designed and manufactured to be the same material as the sewage pipe, such as PE pipe, PP pipe, or PVC pipe, or metal pipe can also be used.
[0034] The water storage pipe 1 and connecting pipe 2 provided by this utility model are pre-installed, meaning that the connecting pipe 2 and the water trap 1 are directly fixed at the factory (various configurations can be provided at the factory, such as...). Figure 1 or Figure 2 When using this device, select a suitable structure and directly install connecting pipe 2 to the sewage pipe on-site, saving time. The specific processing procedure is as follows:
[0035] 1. First, the water outlet 102 of the ceramic water trap 1 is roughened by deglazing.
[0036] 2. Apply special adhesive to the water outlet 102;
[0037] 3. The diameter of the first tube body 201 of the connecting pipe 2 is increased by heating;
[0038] 4. Apply glue to the inner wall of the first pipe body 201 and position it to connect with the water outlet 102.
[0039] 5. The connected devices undergo cooling and shrinkage treatment;
[0040] 6. Seal the gap after splicing the first pipe body 201 and the water outlet 102.
[0041] The water storage pipe 1 and connecting pipe 2 provided by this utility model can also be connected on the construction site. The reducer 202 used is an eccentric reducer with an inclined surface, which can flexibly adjust the height of the second pipe body 203 or the water trap 1 according to the specific construction environment. That is, it adjusts the relative height between the top of the connecting pipe 2 and the bottom of the water trap 1. For example, when the inclined surface of the reducer 202 is facing down, the height of the top of the second pipe body 203 is relatively lower (e.g., Figure 1 As shown), when the inclined surface of the reducer 202 faces upward, the top of the second pipe 203 is at a relatively higher position (e.g., Figure 2 (As shown). During installation, the inclined surface of the reducer 202 can be oriented in any direction, thereby allowing adjustment of the position of the connecting pipe 2 or the trap 1 according to the construction environment.
[0042] The installation process of the water trap device provided by this utility model is as follows:
[0043] First, select a suitable toilet based on its location and the drain pipe location. Figure 1 or Figure 2 The device determines the installation position of the water trap 1 according to the installation position of the squat toilet, ensures that the horizontal bottom 103 of the water trap 1 is in a horizontal state, and uses conventional technical means in the field to connect and fix the water inlet 101 of the water trap 1 to the sewage outlet of the squat toilet. At the same time, a pad is placed at the bottom of the horizontal bottom 103 of the water trap 1 as needed.
[0044] Then, the second pipe body 203 of the connecting pipe 2 is connected to the sewage pipe. The material of the connecting pipe 2 is designed to be the same as that of the sewage pipe. Existing connection methods can be used, such as using PVC special glue to fix the connection.
[0045] The water trap device for a split-type squat toilet provided by this utility model has the following advantages:
[0046] I. Precise Adaptation: Addressing the problem of mismatch between the original water trap and the diameter of the PVC sewage pipe, an innovative variable diameter connecting pipe technology is adopted to achieve a stable connection between the two, solving the installation and sealing problems caused by the difference in pipe diameter and ensuring the stable operation of the drainage system.
[0047] II. Easy Installation and High Durability: All selected accessories are common market specifications, making procurement easy and convenient. The installation process is simple; simply apply sealant to complete the connection, which is then strong and secure.
[0048] 3. Flexible and Adjustable: Breakthrough in achieving flexible adjustment of installation height according to actual site conditions, bidding farewell to the previous dilemma of limited and rigid water trap installation height. Whether it is a complex old house renovation or a diverse new house decoration, it can be perfectly adapted, significantly improving construction flexibility and convenience.
[0049] IV. Eliminating Hidden Dangers: With precise matching connections and sturdy installation, various hidden dangers caused by improper connections are completely eliminated, effectively avoiding frequent water leaks in the bathroom later on, reducing property losses and life inconveniences caused by water leaks, and creating a safe and comfortable living environment.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
