[0029] See also Figure 1-5 The utility model provides a technical solution: a bathtub with a constant temperature function, comprising a bathtub body 1, a soaking chamber 3 is arranged inside the bathtub body 1, a first water outlet 6 is arranged on one side of the bottom of the bathtub body 1, a second water outlet 7 and a water inlet 8 are arranged on the side wall of the bathtub body 1, a heating component 2 for constant temperature of water inside the soaking chamber 3 is arranged on one side of the bathtub body 1, a water inlet pipe 21 and a water outlet pipe 22 are both fixed on one side of the bathtub body 1, the second water outlet 7 is connected to the water outlet pipe 22, the water inlet 8 is connected to the water inlet pipe 21, and an adjusting component 5 for adjusting the size of the soaking chamber 3 is arranged on the other side of the bathtub body 1;

[0030] In order to facilitate the constant temperature of the bathtub body 1 during use, a heating component 2 is provided. The heating component 2 includes a water inlet pipe 21. A water pump 24 is installed at the water outlet end of the water inlet pipe 21. The water outlet end of the water pump 24 is connected to the water outlet pipe 22. The PLC controller 26 transmits an electrical signal to the heating wire 23 and the water pump 24. At this time, the heating wire 23 heats the water inside the water outlet pipe 22. The heating wire 23 is wound around the outside of the water outlet pipe 22. The water pump 24 draws water from the soaking chamber 3 through the water inlet pipe 21 and pumps it to the inside of the water outlet pipe 22 to heat the water. The heated water is transported to the inside of the soaking chamber 3 through the water outlet pipe 22. The bathtub A temperature controller 25 is installed on the outside of the main body 1, and a PLC controller 26 is installed on one side of the temperature controller 25. The signal output end of the temperature controller 25 is electrically connected to the input end of the PLC controller 26, and the output end of the PLC controller 26 is electrically connected to the input ends of the heating wire 23 and the water pump 24. With the cooperation of the PLC controller 26 and the temperature controller 25, the bathtub can detect the water temperature in real time and automatically start the heating component 2 when the water temperature drops, ensuring that the water temperature is always maintained within the comfortable range set by the user, greatly improving the user experience, so that the user does not have to worry about changes in water temperature when enjoying a bath.

[0031] In order to facilitate the adjustment of the size of the soaking chamber 3, an adjustment component 5 is provided, and the adjustment component 5 includes a mounting plate 51 and a support plate 55. One side of the mounting plate 51 is mounted on the top of the bathroom floor, and the support plate 55 is made of high-density polyethylene. A through-screw motor 52 is installed on one side of the mounting plate 51 to control the rotation of the output shaft of the through-screw motor 52. At this time, the output shaft end pushes the screw 53 to move to one side, so that the screw 53 pushes the support plate 55 and the sealing ring 56 to slide seamlessly inside the soaking chamber 3. The output shaft end of the through-screw motor 52 is connected to the screw 53, and the outer side of the support plate 55 is sleeved with a seamless sliding connection to the inner wall of the soaking chamber 3. The sealing ring 56 on the side has an air cavity inside the sealing ring 56, so that when the sealing ring 56 slides inside the soaking chamber 3, water is prevented from leaking from the joint between the soaking chamber 3 and the sealing ring 56. One end of the screw rod 53 is installed on one side of the support plate 55, and a sliding rod 54 is fixed on one side of the support plate 55. The outer side of the sliding rod 54 is movable through the mounting plate 51 and one side of the bathtub body 1 respectively. The screw rod 53 is inserted into the inner side of the through hole 4, and the support plate 55 is located on the inner side of the soaking chamber 3. The support plate 55 is located at different positions to adjust the size of the soaking chamber 3. The user can bathe the child with less water, thereby achieving the purpose of saving water.

[0032] Working principle: When the user is using the bathtub body 1, he only needs to add warm water into the bathtub body 1, and then set the required water temperature in the PLC controller 26. When the temperature controller 25 detects that the water temperature drops, it sends a signal to the PLC controller 26. At this time, the PLC controller 26 sends an electrical signal to the heating wire 23 and the water pump 24. At this time, the heating wire 23 heats the water inside the water outlet pipe 22. The water pump 24 draws the water inside the soaking chamber 3 through the water inlet pipe 21 and pumps it to the inside of the water outlet pipe 22 to heat the water. The heated water is transported to the inside of the soaking chamber 3 through the water outlet pipe 22. When the water temperature reaches the set temperature, the heating wire 23 and the water pump 24 stop working. Through the cooperation of the PLC controller 26 and the temperature controller 25, the bathtub can detect the water temperature in real time, and automatically start the heating component 2 when the water temperature drops, ensuring that the water temperature is always kept within the comfortable range set by the user, greatly improving the user experience, so that the user does not have to worry about changes in water temperature when enjoying a bath.

[0033] When a child is using the bathtub body 1, he only needs to press the switch to control the output shaft of the screw motor 52 to rotate. At this time, the output shaft end pushes the screw 53 to move to one side, so that the screw 53 pushes the support plate 55 and the sealing ring 56 to slide seamlessly inside the soaking chamber 3. The size of the soaking chamber 3 can be adjusted, so that a small amount of water can be added to the soaking chamber 3 to bathe the child. When an adult uses it, he only needs to make the support plate 55 fit one side of the soaking chamber 3 under the action of the screw 53, so that the area of ​​the soaking chamber 3 is maximized, which is suitable for bathing adults. By locating the support plate 55 at different positions and adjusting the size of the soaking chamber 3, the user can bathe the child with less water, thereby achieving the purpose of water saving. The bathtub body 1 can make full use of the space in different usage scenarios. When a larger soaking chamber 3 is not needed, it can be reduced to save space; when a bathing space is needed for adults, it can be expanded to meet the needs, thereby improving the practicality of the bathtub body 1.
