[0002] The mixing valve has a cold water joint and a hot water joint at the same time, which can be respectively connected to the cold water pipeline and the hot water pipeline, so as to mix cold water and hot water, adjust the appropriate water temperature. The user can adjust the proportion of cold water and hot water according to his own needs to make the water temperature more comfortable and avoid scalding. Therefore, the mixing valve will be installed in the front position of the water pipeline system that supplies water to the cold and hot water faucets to ensure the outlet water temperature of the cold and hot water faucets.

[0003] During the actual installation process of the mixing valve, it is very easy to install the mixing valve crooked, resulting in the mixing valve being uneven. When the mixing valve is uneven, it is very easy to cause the connection between the mixing valve and the cold water pipeline and the hot water pipeline to be unstable, and there is a risk of water leakage or bursting. At the same time, it may affect the internal structure and movement of the mixing valve, resulting in unstable water temperature and uneven flow rate. To solve the above problems, generally, a spirit level or a plumb line is used to measure the verticality of the mixing valve during the installation of the mixing valve. However, this installation method is not only troublesome, but also overly dependent on professional measuring tools, resulting in difficulty for the user to install by himself and increasing the installation cost.

[0018] Blocking strips 16 are provided on the inner walls of the left and right sides of the mixing valve body 1 on the upper and lower sides of the insertion plate 15, and the upper and lower blocking strips 16 and the inner wall of the mixing valve body 1 enclose to form the card slot 13.

[0019] A plurality of uniformly distributed limiting claws 17 are provided on the outer walls of the left and right sides of the directional box 5; an inclined surface 18 is provided on the outer side wall of the limiting claw 17, and the rear end of the inclined surface 18 inclines towards the center of the directional box 5; a blocking edge 19 extends outward from the outer edge of the front side wall of the directional box 5.

[0020] The box cover 6 is provided with an operation hole 20 corresponding to the position of the mixing valve body 1; symmetric limiting grooves 21 are provided on the inner walls of the left and right sides of the front end hole opening of the operation hole 20, and the front slot openings of the limiting grooves 21 are located on the front side wall of the box cover 6; an auxiliary cover 22 matching the operation hole 20 is provided in the operation hole 20; limiting blocks 23 matching the limiting grooves 21 are provided on the left and right sides of the outer wall of the auxiliary cover 22; the front end of the auxiliary cover 22 protrudes forward out of the operation hole 20.

[0021] The lower surface of the orientation box 5 is provided with a lower notch 24 communicating with its internal space; a lower baffle 25 is arranged in the lower notch 24; several breakable parts 26 connected to the rear end of the lower baffle 25 are arranged on the rear inner wall of the lower notch 24; the upper surface of the orientation box 5 is provided with several upper notches 27 communicating with its internal space; an upper baffle 28 is arranged in the upper notch 27; the outer walls of the left and right sides of the front end of the upper baffle 28 are connected to the inner walls of the left and right sides of the front end of the upper notch 27; the orientation box 5, the upper baffle 28, the lower baffle 25 and the breakable parts 26 are integrally formed and are all made of plastic materials.

[0022] The cold water joint 2 and the water outlet joint 4 are both located below the mixing valve body 1 and are opposite to the upper surface of the lower baffle 25.

[0023] The using method of the utility model is as follows:

[0024] Since the mixing valve body 1 is fixed on the positioning column 7 through the positioning wing 9, and the positioning wing 9 and the positioning column 7 are fixed through the positioning screw 11, this fixing method can not only accurately position the position of the mixing valve body 1, but also ensure the stability of the mixing valve body 1 when it is arranged in the orientation box 5. The existence of the support plate 12 can further position the position of the mixing valve body 1 and can further play a role in supporting the mixing valve body 1. The existence of the orientation box 5 can protect the mixing valve body 1 inside and effectively avoid the situation that the mixing valve body 1 is damaged. After the mixing valve body 1 is accurately fixed in the orientation box 5, only by ensuring the verticality of the orientation box 5 can the verticality of the mixing valve body 1 be ensured. When installing the orientation box 5, a mounting frame specially matched with the orientation box 5 will be arranged in the wall recess. Just embed the orientation box 5 into the square opening of the mounting frame, and the outer walls of the four sides of the orientation box 5 are attached to the inner walls of the square opening of the mounting frame, which can effectively avoid the situation that the orientation box 5 is inclined after installation, effectively ensure the verticality of the orientation box 5, and thus effectively ensure the verticality of the mixing valve body 1, ensure the balance state of the mixing valve, effectively avoid the situation that the mixing valve is uneven and the connection between it and the cold water pipeline and the hot water pipeline is not firm, and effectively eliminate the hidden dangers of water leakage and explosion. During the whole orientation installation process of the mixing valve body 1, there is no need to rely on special measuring tools, and the installation process is extremely simple. Even without the help of installers, users can easily complete it by themselves. At the same time, the reduction of special measuring tools can effectively reduce the installation cost of the mixing valve.

[0025] Both the inner walls on the left and right sides of the mixing valve body 1 are provided with slots 14. On the left and right sides of the rear side wall of the box cover 6, there are inserted plates 15 that match the slots 14. On the inner walls on the left and right sides of the mixing valve body 1, there are retaining strips 16 located on the upper and lower sides of the inserted plates 15. The retaining strips 16 on the upper and lower sides and the inner wall of the mixing valve body 1 enclose to form a clamping groove 13. Under the restriction of the clamping groove 13, the inserted plates 15 will be restricted from moving up and down, thus effectively ensuring the stability when the box cover 6 is closed on the front side of the orientation box 5. When it is necessary to open the box cover 6, just pull the box cover 6 forward, and the inserted plates 15 will move forward along the track of the slots 14, and finally complete the separation of the box cover 6 from the orientation box 5, which is convenient for operating the mixing valve body 1 in the orientation box 5.

[0026] On the outer walls on the left and right sides of the orientation box 5, there are several uniformly distributed limiting claws 17. On the outer side wall of the limiting claws 17, there is an inclined surface 18, and the rear end of the inclined surface 18 inclines towards the center of the orientation box 5. On the outer edge of the front side wall of the orientation box 5, there extends a retaining edge 19 outward. The inclined surface 18 of the limiting claws 17 is conducive to quickly squeezing into the rear side of the installation frame when the orientation box 5 is installed in the wall recess. Then, the retaining edge 19 on the outer edge of the front side wall of the orientation box 5 can form a restriction on the front side of the installation frame. In the case where the orientation box 5 has two restrictions located on the front and rear sides of the installation frame respectively, the orientation box 5 can be firmly fixed on the installation frame.

[0027] On the box cover 6, there is an operation hole 20 corresponding to the position of the mixing valve body 1. On the inner walls on the left and right sides of the front end orifice of the operation hole 20, there are symmetrically arranged limiting grooves 21. The front side orifice of the limiting grooves 21 is located on the front side wall of the box cover 6. In the operation hole 20, there is an auxiliary cover 22 that matches it. On the left and right sides of the outer wall of the auxiliary cover 22, there are limiting blocks 23 that match the limiting grooves 21. The front end of the auxiliary cover 22 protrudes forward out of the operation hole 20. When the box cover 6 is fully opened, the mixing valve body 1 will be completely exposed to the outside and is extremely vulnerable to external factors. Under normal circumstances, the operation hole 20 can be opened separately through the auxiliary cover 22, and the mixing valve body 1 in the orientation box 5 can be operated through the operation hole 20. This operation method can not only effectively protect the mixing valve body 1 but also operate the mixing valve body 1. When it is necessary to open the auxiliary cover 22, just pull the auxiliary cover 22 forward through the front end of the auxiliary cover 22, and the cooperation between the limiting blocks 23 and the limiting grooves 21 can ensure the stability of the auxiliary cover 22 installed in the operation hole 20.

[0028] The directional box made of plastic can protect the mixing valve body 1 while reducing its own cost. The upper baffle 28 and the lower baffle 25 made of plastic can form a closed space inside the directional box 5, which can comprehensively protect the mixing valve body 1 installed in the directional box 5, thus effectively avoiding the situation that the mixing valve body 1 is knocked during transportation. When the cold water joint 2, the hot water joint 3 and the water outlet joint 4 of the mixing valve body need to be connected to pipelines, the upper baffle 28 and the lower baffle 25 are removed according to actual needs. Since there are several breakable parts 26 connected to the rear end of the lower baffle 25 on the inner wall of the rear side of the lower notch 24, the connection point between the lower baffle 25 and the breakable part 26 can be directly broken by an external force, and the lower baffle 25 can be removed from the lower notch 24. Since the outer walls of the left and right sides of the front end of the upper baffle 28 are connected to the inner walls of the left and right sides of the front end of the upper notch 27, the connection point between the outer walls of the left and right sides of the front end of the upper baffle 28 and the inner walls of the left and right sides of the front end of the upper notch 27 can be directly broken by an external force, and the upper baffle 28 can be removed from the upper notch 27.

[0029] The cold water joint 2 and the water outlet joint 4 are both located on the lower side of the mixing valve body 1 and are opposite to the upper surface of the lower baffle 25. After the lower baffle 25 is removed from the lower notch 24, the external pipeline can directly penetrate into the directional box 5 through the lower notch 24, and the connection between the external pipeline and the mixing valve body 1 can be quickly completed.
