Attached Figure Description

[0012] Figure 1 This is a structural schematic diagram of the water connection pipe fitting in this embodiment. Detailed Implementation

[0013] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0014] See appendix Figure 1 This application provides a water inlet pipe fitting for connecting a water tank and a squat toilet, comprising a vertical pipe body 1 and a horizontal pipe body 2. The bottom end of the vertical pipe body 1 is provided with an elbow 3 connecting to the horizontal pipe body 2. The elbow 3 and the vertical pipe body 1 are integrally formed to prevent water leakage at the connection between the vertical pipe body 1 and the elbow 3. The outer side of the elbow 3 is provided with a positioning protrusion 4. The elbow 3 is provided with a first pipe diameter section 5 and a second pipe diameter section 6 in sequence from the connection end to the positioning protrusion 4. The outer diameter of the first pipe diameter section 5 is smaller than the inner diameter of the horizontal pipe body 2. The horizontal pipe body 2 is sleeved on the outer surface of the second pipe diameter section 6. The horizontal pipe body 2 and the second pipe diameter section 6 are interference-fitted to achieve axial sealing. The horizontal pipe body 2 abuts against the positioning protrusion 4 to achieve radial sealing. The bottom of the elbow 3 is provided with a support foot 7. The support foot can tilt the horizontal pipe body to make drainage smoother and the water discharge impact force greater.

[0015] The length of the second pipe section 6 is 15mm-35mm, and the preferred length of the second pipe section is 25mm and 30mm. This length ensures that the second pipe section has sufficient length to connect with the horizontal pipe body 2, and ensures the sealing of the connection between the second pipe section and the horizontal pipe body.

[0016] The horizontal pipe body 2 is provided with a connecting pipe section 8 at the other end connected to the elbow 3. A positioning flange 9 is provided between the connecting pipe section 8 and the horizontal pipe body 2. The diameter of the positioning flange 9 is larger than the diameter of the connecting pipe section 8. A rubber plug 12 is fitted on the connecting pipe section 8. The connecting pipe section is used to connect to the water inlet of the squat toilet. The positioning flange abuts against the water inlet to prevent the connecting pipe section from extending too far into the squat toilet. The rubber plug can improve the sealing performance and ensure the tightness of the connection between the connecting pipe section and the water inlet of the squat toilet.

[0017] The inner wall of the connecting pipe section 8 is at a lower horizontal height than the inner wall of the horizontal pipe body 2. This structure ensures that the water in the horizontal pipe body can be completely drained, avoiding any residual water in the horizontal pipe body.

[0018] The length of the connecting pipe section 8 is 15mm-25mm, preferably 15mm, 20mm and 25mm. The specific length is selected according to the specific parameters and size of the squat toilet, and there is no restriction here. Within this length range, it can be ensured that there is enough connection length with the squat toilet.

[0019] The top of the vertical pipe body 1 is connected to an extension pipe section 10. The extension pipe section 10 is provided with an insertion section 11 that is inserted into the inner wall of the vertical pipe body 1. The insertion section 11 is interference-fitted with the inner wall of the vertical pipe body 1. The extension pipe section can be added according to the installation height of the water tank to meet the installation requirements of different water tank heights.

[0020] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
