Technical Field
[0001] This utility model relates to the field of hot spring pool technology, specifically to a hot spring pool liquid level control device. Background Technology
[0002] In hot spring resorts, health and wellness centers, the stability of the water level and temperature in the hot spring pool directly determines the user experience and operational safety. As an open or semi-open body of water, the hot spring pool is prone to water level fluctuations due to factors such as splashing water when users enter and exit, natural evaporation, and regular water changes. At the same time, uneven heating during water replenishment can lead to water temperature stratification within the pool, affecting the comfort of the user experience.
[0003] Traditional hot spring pools are typically replenished by direct injection. However, without a dedicated water temperature mixing mechanism, newly added cold or hot water struggles to quickly blend with the existing hot spring water. Direct injection of cold water causes a sudden drop in localized pool temperature, leading to discomfort as users move within the pool. Conversely, direct injection of hot spring water results in sedimentation at the bottom or floating on the surface, creating a layered effect of hot at the top and cold at the bottom, or localized high temperatures. This not only fails to meet the temperature uniformity requirements of hot spring bathing but also poses a risk of scalding due to excessively high localized temperatures. Therefore, this invention provides a hot spring pool level control device to address the problems mentioned in the background section. Utility Model Content
[0004] The purpose of this utility model is to provide a hot spring pool liquid level control device to improve the safety, comfort and operational efficiency of hot spring pools.

[0011] According to one embodiment of the present invention, the water supply solenoid valve and the drain valve are electrically connected to the pressure sensor.
[0012] Compared with the prior art, the beneficial effects of this utility model are: The hot spring pool level control device provided by this utility model, through the cooperation of a connecting pipe and a pressure sensor, utilizes the correlation between water depth and pressure to achieve real-time monitoring and dynamic adjustment of the water level in the hot spring pool, ensuring that the water level remains stable at a specified height and guaranteeing continuous use.

Detailed Implementation
[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] Please see Figure 1As shown, this utility model provides a technical solution: a hot spring pool liquid level control device, including a base 11, the top of the base 11 is fixedly connected to the hot spring pool body 21, a water level monitoring and adjustment mechanism 3 for adjusting the liquid level of the hot spring pool body 21 is provided on one side of the hot spring pool body 21, a water level limiting mechanism 5 for preventing the liquid level from being too high is provided on the other side of the hot spring pool body 21, and a drainage mechanism 4 for draining water is provided inside the hot spring pool body 21.
[0017] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3 As shown, the water level monitoring and adjustment mechanism 3 includes a fixed base 31, which is fixedly connected to the middle of the rear side of the hot spring pool body 21. The top of the fixed base 31 is fixedly connected to a mixing tank 32, and the top of the mixing tank 32 is fixedly connected to a drain tank 33. The two sides of the fixed base 31 are fixedly connected to water inlet pipes 34, and the middle of the water inlet pipes 34 is fixedly connected to a water replenishment solenoid valve 35. The mixing tank 32 is equipped with a rapid mixing component 39 for accelerating the mixing of hot and cold water.
[0018] The rapid mixing assembly 39 includes a lower connecting frame 392 and an upper connecting frame 393. The lower connecting frame 392 is fixedly connected to the bottom of the inner wall of the mixing tank 32, and the upper connecting frame 393 is fixedly connected to the top of the inner wall of the mixing tank 32. An impeller 391 is rotatably connected inside the lower connecting frame 392.
[0019] When the water volume inside the hot spring pool body 21 is insufficient, hot water and cold water are introduced into the two inlet pipes 34 respectively. Then, the water flow impacts the impeller 391 in the rapid mixing component 39, causing it to rotate inside the mixing tank 32, thereby accelerating the mixing of hot and cold water and ensuring that the water discharged by the water level monitoring and regulating mechanism 3 is at a similar temperature to the water inside the hot spring pool body 21.
[0020] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, the water level monitoring and adjustment mechanism 3 also includes a connecting pipe 36, which is fixedly connected to the side of the hot spring pool body 21. A pressure sensor 37 is fixedly connected to the bottom of the connecting pipe 36, and an inlet 38 is provided at the bottom of the side of the hot spring pool body 21, extending into the interior of the connecting pipe 36.
[0021] The drainage mechanism 4 includes a water collection tank 41, which is fixedly connected to the bottom of the inner wall of the hot spring pool body 21. The inner diameter of the water collection tank 41 gradually decreases from top to bottom. An interception net 42 is fixedly connected to the top of the water collection tank 41, and a drain pipe 43 is fixedly connected to the bottom of the water collection tank 41. The drain pipe 43 is located inside the base 11, and a drain valve 44 is fixedly connected to the end of the drain pipe 43 away from the water collection tank 41.
[0022] The water replenishment solenoid valve 35 and the drain valve 44 are electrically connected to the pressure sensor 37. Water inside the hot spring pool body 21 enters the interior of the connecting pipe 36 through the inlet 38. Due to atmospheric pressure, the water level in the connecting pipe 36 is the same as that inside the hot spring pool body 21. The pressure on the pressure sensor 37 varies depending on the water depth, thereby monitoring the water depth inside the hot spring pool body 21 in real time. When the water depth is lower than the preset value, the water replenishment solenoid valve 35 opens and replenishes water into the hot spring pool body 21. When the water depth is too high, the drain valve 44 opens to drain water. By setting an interception net 42 on the top of the water collection tank 41, impurities inside the hot spring pool body 21 are intercepted, thereby preventing the drain pipe 43 from becoming blocked.
[0023] As one implementation method in this embodiment, please refer to Figure 3 and Figure 5 As shown, the water level limiting mechanism 5 includes an overflow box 51, which is fixedly connected to the top front of the hot spring pool body 21. Connecting pipes 52 are fixedly connected to both sides of the bottom of the overflow box 51. One end of the connecting pipe 52 away from the overflow box 51 extends into the interior of the drain pipe 43. A drain trough 53 extending into the interior of the overflow box 51 is provided on the top front of the hot spring pool body 21.
[0024] When the water level inside the hot spring pool 21 is higher than the safety line, the excess water flows into the overflow box 51 and then into the drain pipe 43 through the connecting pipe 52, thereby limiting the maximum water depth.
[0025] Working principle: Water inside the hot spring pool body 21 enters the connecting pipe 36 through the inlet 38. Due to atmospheric pressure, the water level in the connecting pipe 36 is the same as that inside the hot spring pool body 21. The pressure on the pressure sensor 37 varies depending on the water depth, thus monitoring the water depth inside the hot spring pool body 21 in real time. When the water depth is lower than the preset value, the water replenishment solenoid valve 35 opens and replenishes water into the hot spring pool body 21. First, hot water and cold water are introduced into the two inlet pipes 34 respectively. Then, the water flow impacts the impeller 391 in the rapid mixing component 39, causing it to rotate inside the mixing tank 32, mixing the hot and cold water. When the water depth is too high, the drain valve 44 opens to drain the water. An interception net 42 is set at the top of the water collection tank 41 to intercept impurities inside the hot spring pool body 21, thereby preventing the drain pipe 43 from becoming blocked. When the water level inside the hot spring pool body 21 is higher than the safety line, the excess water flows into the overflow box 51 and then into the drain pipe 43 through the connecting pipe 52 and is discharged.
[0026] The aforementioned water level monitoring and regulation mechanism 3 achieves pressure sensing monitoring, automatic water replenishment, and hot and cold water mixing. Water level measurement is achieved through a pressure sensor 37 installed at the bottom of the connecting pipe 36. The water replenishment solenoid valve 35 of the inlet pipe 34 needs to simultaneously control the hot and cold water pipelines. The impeller 391 and mixing tank 32 constitute a rapid mixing assembly 39, which is logic-controlled by a PLC or dedicated controller. Its control logic can be: / / Pseudocode example If the pressure sensor value is less than the lower threshold value, then... Water supply solenoid valve := TRUE; Temperature detection after a 30-second delay (optional); ELSE IF Pressure sensor value > Upper threshold THEN Drain valve := TRUE; END_IF; / / Anti-shake: The signal needs to be triggered continuously for 5 seconds before it will take effect.
[0027] In summary, the hot spring pool level control device, through the cooperation of connecting pipes and pressure sensors, utilizes the correlation between water depth and pressure to achieve real-time monitoring and dynamic adjustment of the pool's water level, ensuring that the water level remains stable at the designated height and guaranteeing continuous use. During water addition, a rapid mixing component instantly and thoroughly blends hot and cold water, ensuring that the newly added water maintains the same temperature as the existing pool water, avoiding discomfort caused by temperature differences and significantly improving user comfort. Furthermore, the addition of a water level limiting mechanism and pressure sensor provides dual protection; even if the pressure sensor malfunctions, it effectively limits the maximum water level, preventing water overflow and thus mitigating safety hazards. This comprehensively enhances the device's stability, safety, and practicality.

Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
