[0040] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0041] AsFigures 1-7 As shown, an acrylic bathtub includes:

[0042] The main body of the tank 1 is an integral structure and is equipped with a drain outlet;

[0043] The support seat 2 is detachably connected to the inner bottom of the tub body 1, and the bottom edge of the support seat 2 is on the same horizontal plane as the bottom edge of the tub body 1. A deformable connecting pipe is detachably connected to the support seat 2. In this embodiment, the connecting pipe is a PVC drain hose. The connection between the connecting pipe and the support seat 2 can be achieved by changing the bending of the PVC drain hose. When installing the bathtub, it can accommodate a longer connecting pipe. The position of the connecting pipe can be adjusted by bending, eliminating the need to cut and adjust the length of the connecting pipe. At the same time, the bent connecting pipe can slow down the flow rate of water during drainage through the bending structure, thereby avoiding repeated impacts on the free end of the connecting pipe due to excessive water flow. The support seat 2 is provided with a limiting port 21 in the same axial direction as the drain outlet. The bottom surface of the support seat 2 is concave to form several positioning grooves 22 that communicate with the limiting port 21. The several positioning grooves 22 form a mesh structure on the bottom surface of the support seat 2 for fixing the connecting pipe. The fixing channel is provided with several adjustable connecting ports that are coaxial with the drain outlet.

[0044] like Figure 2 As shown, the bathtub body 1 includes an integral inner cylinder 11 and an outer baffle 12. The bottom surface of the inner cylinder 11 is higher than the bottom surface of the outer baffle 12. The cavity of the inner cylinder 11 is trapezoidal. The inclination angle of one side of the inner cylinder 11 is greater than the inclination angle of the opposite side. The top surface of the support seat 2 is provided with limiting parts 23 that respectively fit against the bottom edges of the two sides. The contact surfaces of the two limiting parts 23 with the inner cylinder 11 are arc-shaped. By making the bottom surface of the inner cylinder 11 higher than the bottom surface of the outer cylinder, a space is formed to accommodate the support seat 2. Before installing the bathtub, the positioning of the support seat 2 facilitates the installation of the bathtub. Furthermore, the support seat 2 provides a certain degree of support for the inner cylinder 11, thereby improving the load-bearing capacity of the bathtub during use. Furthermore, the inclination angle of one side of the inner tub 11 is greater than that of the opposite side, which provides a clear and intuitive indication of the bathtub's placement direction. The inclination angle also allows bathers to lie comfortably in the bathtub. Due to the different inclination angles of the two sides, the top surfaces of the support seat 2 form two limiting parts 23 that match the edge structure of the sides. The difference between the limiting parts 23 further positions and edges the bathtub, providing upward support for the inner tub 11 and enhancing the stability of the bathtub's placement with the edging support of the limiting parts 23. This also achieves a better pre-fixing effect when sealing and fixing the bottom of the bathtub.

[0045] The thickness of the bearing seat 2 is equal to the vertical distance from the inner cylinder 11 to the lowest point of the peripheral baffle 12, and the bottom of the bearing seat 2 is formed with a plurality of positioning protrusions 24 at the intersection of the fixed channels, which are used to provide a vertical downward force on the connecting pipe. By means of the positioning protrusions 24 at the intersection, the connecting pipe can pass through the intersection and press the connecting pipe when the bearing seat 2 is placed on the ground, thereby fixing the position of the connecting pipe and avoiding deformation or movement of the connecting pipe during use, which can cause water leakage and other situations.

[0046] The preparation method of the bearing seat 2 includes:

[0047] Step one: according to the shape and structure of the bearing seat 2, a corresponding blow-suction mold is prepared in a reverse mold manner;

[0048] Step two: install the blow-suction mold on the suction machine, and fix the suctioned acrylic material plate with the tooling;

[0049] Step three: heat the clamped and fixed acrylic material plate;

[0050] Step four: start the suction machine to suction the heated acrylic material plate, and simultaneously, the suctioned air is uniformly inflated to the other side of the acrylic material plate through the inflation port of the blow-suction mold;

[0051] Step five: after suction forming, keep pressure for 10-20 minutes, and cool to shape fixation, then take down the bearing seat 2 embryo and continue to cool;

[0052] Step six: evenly spray UV glue on the protruding surface of the cooled bearing seat 2 embryo, and adhere glass fibers and then defoam and solidify.

[0053] Step seven: open a hole in the naturally solidified bearing seat 2 embryo to form a limiting port 21 coaxial with the drain port

[0054] The specific steps of the assembly method include:

[0055] The carrier seat 2 is pre-assembled to the designated position, the distance between the carrier seat 2 and the building wall is compared with the size difference of the cylinder main body 1, then the position of the adjustable connecting port is aligned with the drain port on the building body, then one end of the connecting pipe is limited in the adjustable connecting port and extends into the drain port, the middle section of the connecting pipe is bent and deformed to be embedded into the fixed channel, so that the other end of the connecting pipe penetrates through the limiting hole 21, and the carrier seat 2 can be pre-fixed by using adhesive. During the installation of the carrier seat 2 and the connecting pipe, the end of the connecting pipe is inserted into the drain port on the building body, the connecting pipe is embedded into the fixed channel at the bottom of the carrier seat 2, and the other end penetrates through the limiting hole, then the position of the middle section of the connecting pipe is adjusted, the connecting pipe is bent, the number of bending is controlled according to the length of the connecting pipe, if the drain port is far away from the position of the limiting hole 21, the bending angle of the connecting pipe can be adjusted to 1-2, if the drain port is close to the position of the limiting hole 21, the connecting pipe can be adjusted to form 3-4 bending angles, when the water flows through the limiting hole 21 and the connecting pipe, the flow rate can be slowed down through the bending angles, so as to further avoid the situation that the connecting pipe is displaced due to sudden change of water flow at the moment when the connecting pipe starts to drain, and water leakage is caused.

[0056] During the installation of the cylinder main body 1, the drain port of the cylinder main body 1 is assembled to the limiting hole 21 on the carrier seat 2, the end of the connecting pipe is nested in the drain port, and finally the drain piston is connected with the connecting pipe. During the connection of the drain piston and the connecting pipe, the adapter of the drain piston is inserted into the end of the connecting pipe, the adapter is located at the bottom end of the inner cylinder body 11 and is threadedly connected with the bottom limiting cover, then the upper limiting cover is threadedly connected above the adapter, so as to fix the inner cylinder body 11, finally the piston core is installed, and the assembly of the bathtub is completed.

[0057] The above is only the preferred embodiment of the present application, the protection scope of the present application is not limited to the above-mentioned embodiment, any technical scheme belonging to the idea of the present application is within the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
