Detailed implementation manner

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0029] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0030] As Figure 1 shown, the present utility model provides an automatic circulation thermostat for a bathtub, including a thermostat body 1 and a pipeline 4. The pipeline 4 is installed on the surfaces of the drain pipe 3 and the water inlet pipe 2. The surface of the thermostat body 1 is communicated with the water inlet pipe 2. One side of the thermostat body 1 far from the water inlet pipe 2 is communicated with the drain pipe 3. Sealing devices 5 are provided on the surfaces of the drain pipe 3 and the water inlet pipe 2, and a fixing device 6 is provided on the surface of the thermostat body 1.

[0031] Next, the specific settings and functions of its sealing device 5 and fixing device 6 will be specifically described.

[0032] As Figure 2 and Figure 3As shown, the sealing device 5 includes two circular plates 58. The circular plates 58 are fixedly connected to the surface of the drain pipe 3 or the water inlet pipe 2. A rectangular hole 52 is formed on the surface of the circular plate 58. A fixing block 51 is fixedly connected to the arc surface of the pipe 4. The fixing block 51 is slidably connected to the inner wall of the rectangular hole 52. A sealing gasket 53 is installed on the surface of the circular plate 58. A screw 54 is threadedly connected to the surface of the fixing block 51. Circular grooves 55 are formed on the surfaces of both the water inlet pipe 2 and the drain pipe 3. The screw 54 is slidably connected to the circular groove 55. By providing the sealing device 5, through the mutual cooperation among the fixing block 51, the rectangular hole 52, the sealing gasket 53, the screw, the circular groove 55 and the circular plate 58, the connection between the drain pipe 3 and the water inlet pipe 2 and the pipe 4 can be sealed, preventing the leakage of the constant temperature medium at the connection of the pipe 4. It is convenient to observe the damage or oxidation of the sealing gasket 53 part, so as to make a judgment and replace it quickly. Quickly replacing the sealing gasket 53 can ensure good sealing performance of the equipment, thereby improving the accurate control and stability of the thermostat for temperature. A pointed cone 56 is fixedly connected to the surface of the circular plate 58. Two spines 57 are fixedly connected to the surface of the pointed cone 56. The pointed cone 56 and the spines 57 are both located within the sealing gasket 53. Place the sealing gasket 53 on the surface of the circular plate 58, and then press the sealing gasket 53. At this time, the pointed cone 56 and the spines 57 will insert into the sealing gasket 53, and the pointed cone 56 and the spines 57 play a role in fixing the sealing gasket 53, preventing the sealing gasket 53 from shifting during use. At the same time, tearing off the sealing gasket 53 can facilitate the regular replacement of the sealing gasket 53. A flexible gasket 59 is adhesively bonded to the inner wall of the circular groove 55. The flexible gasket 59 is made of rubber. A hexagonal notch is formed at one end of the screw 54. One end of the screw 54 abuts against the surface of the flexible gasket 59. The flexible gasket 59 plays a role in protecting the circular groove 55, thereby being able to protect the water inlet pipe 2 and the drain pipe 3, preventing damage to the water inlet pipe 2 and the drain pipe 3 due to excessive extrusion force of the screw 54. A hexagonal notch is formed at one end of the screw 54. When the edge of the screw 54 becomes round after long-term use, the staff can still rotate the screw 54 by using the hexagonal notch, greatly extending the service life of the screw 54. Bevels are formed on the surfaces of both the rectangular hole 52 and the fixing block 51. The surfaces of the fixing block 51 and the rectangular hole 52 are beveled. The bevel plays a role in facilitating the quick installation of the fixing block 51, preventing the situation that it is difficult to dock due to the high adaptability between the fixing block 51 and the rectangular hole 52, and improving the working efficiency of docking the pipe 4.

[0033] As Figure 1 and Figure 4As shown, the fixing device 6 includes a lead screw 61, which is threadedly connected to the thermostat body 1. One end of the lead screw 61 is fixedly connected to a handle 62, and the end of the lead screw 61 away from the handle 62 is rotatably connected to a clamping plate 63. By providing the fixing device 6, the thermostat body 1 can be installed and fixed quickly and simply, shortening the installation and disassembly time and eliminating the cumbersome screw fixing steps, making the installation of the thermostat more efficient. In addition, the fixing device 6 can also adapt to objects of different widths and flexibly meet various installation requirements, further improving the installation efficiency of the thermostat. The surface of the clamping plate 63 is adhesively bonded with an anti-slip pad 66, and the surface of the anti-slip pad 66 is fixedly connected with bumps 65. The anti-slip pad 66 is made of rubber. When the anti-slip pad 66 abuts against the object to be installed, the thermostat body 1 can be installed and fixed at this time. The anti-slip pad 66 plays a role in increasing the friction force, thereby improving the stability of the installation of the thermostat body 1. A guide rod 64 is fixedly connected to the side of the clamping plate 63 relative to the anti-slip pad 66, and the guide rod 64 is slidably connected to the thermostat body 1. During the movement of the clamping plate 63, the guide rod 64 will be driven to move. The guide rod 64 can prevent the clamping plate 63 from rotating together with the lead screw 61.

[0034] The overall working principle is that when the thermostat needs to be used, it needs to be docked through the pipe 4 for the transportation of the constant temperature medium. First, place the gasket 53 on the surface of the circular plate 58, and then press the gasket 53. At this time, the pointed cone 56 and the barb 57 will insert into the gasket 53, and the pointed cone 56 and the barb 57 play a role in fixing the gasket 53 to prevent the gasket 53 from shifting during use. At the same time, tearing off the gasket 53 can facilitate the regular replacement of the gasket 53. Subsequently, push the pipe 4 in the direction close to the circular plate 58, and the pipe 4 will drive the fixed block 51 to slide along the inner wall of the rectangular hole 52. The surfaces of the fixed block 51 and the rectangular hole 52 are inclined planes, and the inclined planes play a role in facilitating the rapid installation of the fixed block 51, avoiding the situation where the fitting degree of the fixed block 51 and the rectangular hole 52 is too high and it is difficult to dock, improving the working efficiency of docking the pipe 4, and making one end of the pipe 4 closely fit with the gasket 53. Then rotate the screw 54, and the screw 54 moves by means of the thread in the fixed block 51. The screw 54 slides along the inner wall of the circular groove 55 until one end of the screw 54 abuts against the surface of the flexible pad 59. The flexible pad 59 plays a role in protecting the circular groove 55, thereby being able to protect the water inlet pipe 2 and the drain pipe 3, avoiding the situation where the water inlet pipe 2 and the drain pipe 3 are damaged due to excessive extrusion force of the screw 54. A hexagonal notch is provided at one end of the screw 54. When the screw 54 is used for a long time and the edge of the screw 54 becomes round due to rotation, the staff can still rotate the screw 54 by using the hexagonal notch, greatly extending the service life of the screw 54. By setting the sealing device 5, through the mutual cooperation between the fixed block 51, the rectangular hole 52, the gasket 53, the screw, the circular groove 55 and the circular plate 58, the connection between the drain pipe 3 and the water inlet pipe 2 and the pipe 4 can be sealed, preventing the leakage of the constant temperature medium at the connection of the pipe 4, facilitating the observation of the damage or oxidation of the gasket 53 part, and thus making a judgment for rapid replacement. Rapid replacement of the gasket 53 can ensure good sealing of the equipment, thereby improving the accurate control and stability of the thermostat for temperature.

[0035] When the thermostat body 1 needs to be installed and fixed, first rotate the handle 62. The handle 62 will drive the lead screw 61 to rotate. The rotation of the lead screw 61 will drive the clamping plate 63 to move. The movement of the clamping plate 63 will drive the anti-slip pad 66 to move until the anti-slip pad 66 abuts against the object to be installed. At this time, the thermostat body 1 can be installed and fixed. The anti-slip pad 66 plays the role of increasing friction, thereby improving the stability of the installation of the thermostat body 1. During the movement of the clamping plate 63, it will drive the guide rod 64 to move. The guide rod 64 can prevent the clamping plate 63 from rotating together with the lead screw 61. By setting the fixing device 6, the thermostat body 1 can be installed and fixed quickly and simply, shortening the installation and disassembly time and eliminating the cumbersome screw fixing steps, making the installation of the thermostat more efficient. In addition, the fixing device 6 can also adapt to objects of different widths, flexibly coping with various installation requirements and further improving the installation efficiency of the thermostat.
