[0026] As Figures 1 to 4As shown in the figure, a durable foot flushing valve, comprising a valve body 1, the valve body 1 comprises a top cover 101 and a spring 102, the lower surface of the top cover 101 is provided with a positioning mechanism 2 for limiting the movement path of the top cover 101, the front and rear inner walls of the positioning mechanism 2 are installed on the front and rear outer surfaces of the valve body 1, the front surface of the positioning mechanism 2 is provided with a clamping groove, and the clamping groove of the positioning mechanism 2 is provided with a protection mechanism 3; Specifically, by installing the front and rear inner walls of the positioning mechanism 2 on the front and rear outer surfaces of the valve body 1, and moving the positioning mechanism 2 synchronously with the top cover 101, the subsequent positioning mechanism 2 limits the movement path of the top cover 101 during the downward movement, thereby avoiding the bending of the connection between the top cover 101 and the valve body 1 during the subsequent use of the inclined angle to step on the top cover 101, thereby prolonging the service life of the subsequent valve body 1.

[0027] As shown in the figure, Figure 1 , Figure 2 and Figure 4 , the positioning mechanism 2 comprises a fixed ring 203 and two groups of connecting blocks 201, the fixed ring 203 is installed on the outer surface of the top cover 101, and the two groups of connecting blocks 201 are installed on the front and rear sides of the valve body 1, respectively, the upper surfaces of the two groups of connecting blocks 201 are provided with through holes, the through holes of the two groups of connecting blocks 201 are slidably connected with fixed rods 202, and the upper surfaces of the two groups of fixed rods 202 are installed on the lower surface of the top cover 101; Specifically, by installing the fixed ring 203 on the outer surface of the top cover 101, the subsequent user can drive the fixed ring 203 and the two groups of fixed rods 202 to move downward during the process of stepping on the top cover 101, and by slidably connecting the two groups of fixed rods 202 in the through holes of the two groups of connecting blocks 201, the subsequent positioning mechanism 2 limits the movement path of the top cover 101 during the downward movement, thereby avoiding the bending of the connection between the top cover 101 and the valve body 1 during the subsequent use of the inclined angle to step on the top cover 101, thereby prolonging the service life of the subsequent valve body 1.

[0028] As shown in the figure, Figure 2 and Figure 3 , the distance between the lower surfaces of the two groups of fixed rods 202 and the lower surface of the valve body 1 is the same as the maximum compression length of the spring 102; Specifically, by making the distance between the lower surfaces of the two groups of fixed rods 202 and the lower surface of the valve body 1 the same as the maximum compression length of the spring 102, the spring 102 is compressed to the maximum length when the lower surfaces of the two groups of fixed rods 202 abut to the ground, thereby limiting the downward movement of the top cover 101, thereby avoiding the excessive downward movement of the top cover 101 during use, which causes the spring 102 to be excessively compressed and damaged, thereby prolonging the service life of the spring 102.

[0029] As shown in the figure, Figure 1 andFigure 2 As shown, the protective mechanism 3 includes an arc-shaped baffle 302. A slot is provided on the front of a set of connecting blocks 201 on the front side. The arc-shaped baffle 302 is slidably connected to the slot of the set of connecting blocks 201 on the front side. A slider 301 is provided on the front of the arc-shaped baffle 302. The slider 301 is installed on the lower surface of the fixed ring 203. Specifically, by positioning the slider 301 in front of the two sets of connecting blocks 201 and the two sets of fixing rods 202, the arc-shaped baffle 302 can block the two sets of connecting blocks 201 and the two sets of fixing rods 202, thereby minimizing the splashing of excrement secreted by the user onto the outer surface of the two sets of connecting blocks 201 and the two sets of fixing rods 202, which would cause corrosion and damage to the two sets of connecting blocks 201 and the two sets of fixing rods 202 during use. This improves the service life of the subsequent positioning mechanism 2.

[0030] like Figure 2 As shown, the lower surface of the slider 301 is parallel to the lower surface of the front set of fixing rods 202. Specifically, by keeping the lower surface of the slider 301 parallel to the lower surface of the front set of fixing rods 202, the subsequent protective mechanism 3 is prevented from blocking the subsequent spring 102 from being compressed during use, thus preventing the subsequent valve body 1 from properly conveying water flow.

[0031] like Figure 2 and Figure 4 As shown, both the upper and lower surfaces of the two sets of connecting blocks 201 are provided with annular scrapers 4, and the inner walls of the four sets of annular scrapers 4 respectively abut against the outer surfaces of the two sets of fixing rods 202. Specifically, by having the inner walls of the four sets of annular scrapers 4 abut against the outer surfaces of the two sets of fixing rods 202 respectively, the four sets of annular scrapers 4 scrape away the debris accumulated on the outer surfaces of the two sets of fixing rods 202 during the sliding process of the two sets of fixing rods 202 inside the through holes of the two sets of connecting blocks 201, thereby minimizing the risk of blockage in the through holes of the two sets of connecting blocks 201, which would prevent the subsequent positioning mechanism 2 from functioning properly.

[0032] In summary: by fixing the circular ring 203 on the outer surface of the top cover 101, so that the subsequent user in the process of stepping on the top cover 101 synchronously drives the fixed circular ring 203 and the two groups of fixed rods 202 to move downward, and then the two groups of fixed rods 202 are respectively slidably connected inside the through holes of the two groups of connecting blocks 201, so that the subsequent positioning mechanism 2 limits the movement path of the top cover 101 during the downward movement, thereby avoiding the bending of the connection between the top cover 101 and the valve body 1 during the use of the inclined angle stepping on the top cover 101 by the subsequent user; the interval between the lower surfaces of the two groups of fixed rods 202 and the lower surface of the valve body 1 is the same as the maximum compression length of the spring 102, so that the spring 102 is compressed to the maximum length when the lower surfaces of the two groups of fixed rods 202 abut to the ground, thereby limiting the position of the downward movement of the top cover 101 by the two groups of fixed rods 202, thereby avoiding the excessive downward movement of the top cover 101 during use and causing damage to the spring 102 due to excessive compression.

[0033] At the same time, by setting the position of the sliding block 301 at the front side of the two groups of connecting blocks 201 and the two groups of fixed rods 202, the arc-shaped baffle 302 can shield the two groups of connecting blocks 201 and the two groups of fixed rods 202, thereby avoiding the splashing of the subsequent user's excretion to the outer surfaces of the two groups of connecting blocks 201 and the two groups of fixed rods 202, which can cause corrosion and damage to the two groups of connecting blocks 201 and the two groups of fixed rods 202 during use; by abutting the inner walls of the four groups of annular scrapers 4 to the outer surfaces of the two groups of fixed rods 202, the four groups of annular scrapers 4 can scrape off the foreign matter accumulated on the outer surfaces of the two groups of fixed rods 202 during the sliding of the two groups of fixed rods 202 inside the through holes of the two groups of connecting blocks 201, thereby avoiding the blockage of the through holes inside the two groups of connecting blocks 201, which can cause the subsequent positioning mechanism 2 to be unable to be normally used.

[0034] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application.
