[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0040] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can also be the communication inside two components. It can be a wireless connection or a wired connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0041] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0042] Traditional liquid temperature control methods mainly rely on thermodynamic principles and traditional temperature control devices, such as hot plates, coolers, heaters and other devices to achieve. For example, when the liquid temperature is low, heat the liquid or stop cooling; when the liquid temperature is high, cool or stop heating. And, during the liquid transportation process, due to the intervention of external environmental factors, heat dissipation may cause inconsistencies between the actual temperature and the expected set temperature of the new fluid. Therefore, currently, during the process of adjusting the liquid temperature, there are problems of large temperature fluctuations and low control accuracy.

[0043] In view of this, the present utility model provides a temperature adjustment device to solve the problems of large temperature fluctuations and low control accuracy during the process of adjusting the liquid temperature.

[0044] The following combines Figures 1 to 2 , to describe the embodiments of the present utility model.

[0045] According to an embodiment of the present utility model, on the one hand, a temperature adjustment device is provided. The temperature adjustment device includes: a liquid pumping component 1, a mixer 2, a liquid outlet pipeline 3, a return pipeline 5, a transmission pipeline 6, a temperature detection component 7, and a main control unit.

[0046] Specifically, in this embodiment, a plurality of liquid pumping components 1 are provided, and the input ends of each liquid pumping component 1 are connected to a liquid source component 4. The liquid pumping component 1 will pump the liquid supplied by the liquid source component 4, and then heat the liquid and monitor the flow rate. The liquid pumping component 1 can also first heat the liquid supplied by the liquid source component 4, and then pump the heated liquid and monitor the flow rate. The liquid source component 4 can be a faucet, or a first liquid injection pipeline 42, or directly introduce tap water.

[0047] Further, the mixer 2 is provided with a liquid outlet and a plurality of liquid inlets. Each liquid inlet is simultaneously and correspondingly connected to the output end of each liquid pumping component 1 one by one. One end of the transmission pipeline 6 is connected to the liquid outlet. In this way, each liquid pumping component 1 will input the heated liquid into the mixer 2 for mixing, and the mixed liquid is transmitted through the transmission pipeline 6. The mixer 2 can be a static mixer 2, a dynamic mixing pump, such as a screw pump or a gear pump, or a mixing tank.

[0048] During the actual working process, each liquid pumping component 1 first pumps in a predetermined amount of liquid, and then each liquid pumping component 1 has its own set heating temperature. For example, the set heating temperature of the first liquid pumping component 1 is 30 °C, the set heating temperature of the second liquid pumping component 1 is 40 °C, and the set heating temperature of the third liquid pumping component 1 is 50 °C. Each liquid pumping component 1 will heat the liquid inside, which can be heated before pumping or after pumping, as long as the liquid in each liquid pumping component 1 can be heated to its own set heating temperature. After the heating is completed, according to the volume of the mixer 2 and the target temperature set by the user, each liquid pumping component 1 restricts the flow rate of the pumped liquid so that the temperature of the mixed liquid in the mixer 2 meets the target temperature. For example, the target temperature can be 45 °C.

[0049] Of course, this embodiment only gives examples of the number of liquid pumping components 1 and the set heating temperature, but does not limit this. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0050] Further, the temperature detection component 7 is used to detect the liquid temperature on the transmission pipeline 6. For example, it can be set on the transmission pipeline 6 near one end of the liquid outlet pipeline 3 and the return pipeline 5, or it can be set on the transmission pipeline 6 near one end of the mixer 2. Preferably, it is set on the transmission pipeline 6 near one end of the liquid outlet pipeline 3 and the return pipeline 5. Of course, this embodiment only gives examples of the installation position of the temperature detection component 7, but does not limit this. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0051] During the actual working process, the temperature detection component 7 is used to judge whether there is heat loss or the like in the mixed liquid on the transmission pipeline 6, resulting in not meeting the user's usage requirements. The temperature detection component 7 can be of types such as a temperature sensor, an infrared sensor, a thermal resistor, etc. Of course, this embodiment only gives examples of the type of the temperature detection component 7, but does not limit this. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0052] Further, the other ends of the liquid outlet pipeline 3, the return pipeline 5, and the transmission pipeline 6 are simultaneously connected to both the liquid outlet pipeline 3 and the return pipeline 5; a first valve 31 is provided on the liquid outlet pipeline 3; a second valve 51 is provided on the return pipeline 5; the main control unit is electrically connected to each liquid pumping component 1, the temperature detection component 7, the first valve 31, and the second valve 51. In this embodiment, the other end of the liquid outlet pipeline is used to discharge the liquid meeting the target temperature. This embodiment does not limit the environment connected to the other end of the return pipeline 5. For example, it can be connected to the outside or to other containers specifically used for recycling liquids. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved. The main control unit is a controller in the prior art, and the main control unit can be used to control the liquid pumping component 1, the temperature detection component 7, the first valve 31, and the second valve 51 to work. It should be noted that in this embodiment, it is intended to represent the connection relationship of each component, rather than protecting the specific control logic of the main control unit.

[0053] During the actual working process, the liquid is transmitted on the transmission pipeline 6 after being mixed in the mixer 2. At this time, the temperature detection component 7 performs real-time temperature detection on the transmitted liquid. When the temperature detection component 7 detects that the temperature of the transmitted liquid is the target temperature, the main control unit controls the first valve 31 to open and the second valve 51 to close, so that the transmission pipeline 6 is connected to the liquid outlet pipeline 3 and the return pipeline 5 is closed, and the liquid is discharged through the liquid outlet pipeline 3. When the temperature detection component 7 detects that the temperature of the transmitted liquid is not the target temperature, the main control unit controls the second valve 51 to open and the first valve 31 to close, so that the transmission pipeline 6 is connected to the return pipeline 5 and the liquid outlet pipeline 3 is closed, and the liquid is discharged through the return pipeline 5, thereby improving the control accuracy of the temperature and reducing the temperature fluctuation. After receiving the temperature data detected by the temperature detection component 7, the main control unit compares it with the preset target temperature. If a deviation is detected, it calculates the amount of liquid to be supplemented. Then it controls the liquid pumping component 1 to pump in the required amount of liquid to be supplemented to adjust the mixing ratio. After adjustment, the temperature detection component 7 continues to monitor the liquid temperature and feeds the new temperature data back to the main control unit, forming a closed-loop monitoring, thereby improving the overall temperature adjustment accuracy.

[0054] In summary, in the embodiment of the present utility model, by providing the liquid pumping assembly 1 and the mixer 2, during the actual working process, the liquid pumping assembly 1 can be used to pump in the liquid first, and then the liquid is heated. It is also possible to first use the liquid pumping assembly 1 to heat the liquid and then pump in the heated liquid. Finally, each liquid pumping assembly 1 monitors the pumping flow rate of its respective liquid, and according to the actual magnitude of the pumping flow rate, controls whether to continue pumping in the liquid, so that liquids at different temperatures can be pumped in, and the final temperature of the mixed liquid in the mixer 2 is adjusted by the ratio between the liquids at different temperatures. By further providing the return pipeline 5, when the liquid is detected not to meet the target temperature during the transmission process, the second valve 51 is opened and the first valve 31 is closed, so that the liquid that does not meet the temperature can be discharged. When the liquid temperature meets the target temperature, the first valve 31 is opened and the second valve 51 is closed, so that the liquid that meets the temperature can be obtained, and the overall control accuracy of the temperature is improved.

[0055] Further, in an alternative embodiment, as Figure 1 shown, the liquid source assembly 4 includes a first liquid tank 41 and a first liquid injection pipeline 42. In this embodiment, the first liquid tank 41 is adapted to hold the liquid, and the input ends of the liquid pumping assemblies 1 extend into the first liquid tank 41. The first liquid injection pipeline 42 is connected to the first liquid tank 41 and is used for inputting liquid into the first liquid tank 41. The liquid source assembly further includes a liquid source. The liquid source can be a faucet, tap water, or a container filled with liquid. This embodiment is only an example of the liquid source, and those skilled in the art can make changes according to the actual situation.

[0056] Further, in an alternative embodiment, the other end of the return pipeline 5 is connected to the first liquid tank 41. When the temperature of the output liquid does not meet the target temperature, the liquid can be directly discharged into the first liquid tank 41 for recycling.

[0057] Further, in an alternative embodiment, a seal is detachably connected to the end of the first liquid injection pipeline 42 away from the first liquid tank 41. The seal can be a sealing cover or a sealing plug and other sealing structures. Of course, this embodiment is only an example of the type of the seal, but it is not limited thereto, and those skilled in the art can make changes according to the actual situation as long as the same technical effect can be achieved.

[0058] Further, in an alternative embodiment, the liquid pumping assembly 1 includes a liquid pump 11, a flow sensor 12, a temperature detector 14, a temperature control unit 16, and a third valve 17.

[0059] Specifically, in this embodiment, the liquid pump 11 is used to provide the power for transporting the liquid, and it can be of types such as centrifugal pump, gear pump, screw pump, plunger pump, etc. The liquid inlet end of the liquid pump 11 is connected to the first liquid tank 41 through the third valve 17. The third valve 17 functions as a liquid switch and is used to control the pumping of liquid from the first liquid tank 41. When the third valve 17 is opened, the liquid pump 11 can pump liquid from the first liquid tank 41. When it comes to the third valve 17, the liquid pump 11 cannot pump liquid from the first liquid tank 41. The liquid outlet end of the liquid pump 11 is communicated with the liquid inlet of the mixer 2. Along the liquid inlet direction of the liquid pumping assembly 1, between the liquid outlet end of the liquid pump 11 and the liquid inlet of the mixer 2, a flow sensor 12, a temperature control device 16, and a temperature detector 14 are sequentially arranged. The temperature control device 16 is used to heat the liquid. Regarding the specific installation position of the flow sensor 12, along the liquid flow direction, the flow sensor 12 can be arranged upstream or downstream of the liquid pump 11. This embodiment does not limit this, as long as the flow sensor 12 can measure the rate or total amount of liquid flow.

[0060] The main control unit is electrically connected to the liquid pump 11, the flow sensor 12, the temperature control device 16, and the temperature detector 14 at the same time. The main control unit can obtain the pumping flow rate of the liquid pump 11 in real time through the flow sensor 12, and then adjust the working state of the liquid pump 11. That is, when the pumping flow rate meets the requirements, it controls the liquid pump 11 to stop operating. When the pumping flow rate does not meet the requirements, it controls the liquid pump 11 to continue operating.

[0061] Furthermore, in this embodiment, the temperature control device 16 can heat the pumped liquid, and then the liquid pump 11 outputs the heated liquid to the mixer 2. And the temperature detector 14 is used to detect the temperature of the liquid pumped by the liquid pump. Of course, along the liquid flow direction, the temperature detector 14 needs to be located downstream of the temperature control device 16. Regarding the type of the temperature detector 14, the temperature detector 14 can be of types such as temperature sensor, infrared sensor, thermal resistor, temperature detection probe, etc. Of course, this embodiment is only an example of the type of the temperature detector 14, but it does not limit this. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0062] Furthermore, in this embodiment, the temperature control device 16 is electrically connected to the main control unit, which can ensure that the liquid is heated to the temperature set by the liquid pumping assembly 1.

[0063] Further, as another alternative embodiment, the liquid source assembly 4 includes a plurality of second liquid tanks 43 and a plurality of second liquid injection pipelines 44. In this embodiment, the number of the second liquid tanks 43, the number of the liquid pumping assemblies 1, and the number of the second liquid injection pipelines 44 are the same; each of the second liquid tanks 43, each of the liquid pumping assemblies 1, and each of the second liquid injection pipelines 44 are correspondingly arranged. Each of the second liquid injection pipelines 44 is respectively communicated with each of the second liquid tanks 43 for inputting liquid into each of the second liquid tanks 43; the input ends of each of the liquid pumping assemblies 1 respectively extend into their corresponding second liquid tanks 43. Further, in this alternative embodiment, the number of the liquid pumping assemblies 1 can also be adjusted so that the number of the liquid pumping assemblies 1 is different from the number of the second liquid tanks 43. For example, the input ends of a plurality of the liquid pumping assemblies 1 can be simultaneously extended into the same second liquid tank 43, so that the number of the second liquid tanks 43 can be reduced.

[0064] Further, in this alternative embodiment, the other end of the return pipeline 5 is communicated with at least one second liquid tank 43. That is to say, the other end of the return pipeline 5 can be communicated with one second liquid tank 43, or can be simultaneously communicated with a plurality of second liquid tanks 43. There is no limit on the number of connections with the second liquid tanks 43.

[0065] With such an arrangement, in the embodiment of the present utility model, by communicating the return pipeline 5 with the second liquid tank 43, when the liquid temperature does not meet the requirements, it is not necessary to discharge the liquid, but the liquid can be directly transported to the second liquid tank 43, thereby avoiding waste of liquid resources. And the liquid can be reheated by the liquid pumping assembly 1 again and then transported to the mixer 2 again to realize the reuse of liquid resources.

[0066] Further, in this alternative embodiment, the liquid pumping assembly 1 includes a liquid pump 11, a flow sensor 12, a heater 13, a temperature detector 14, and a third valve 17. The liquid pump 11 is used to provide the power for transporting the liquid, and can be of types such as a centrifugal pump, a gear pump, a screw pump, a plunger pump, etc.

[0067] Specifically, in this alternative embodiment, the heater 13 and the temperature detector 14 are both disposed in the second liquid tank 43. The specific setting method is not limited and can be fixed by a detachable connection method, such as bolts. The liquid inlet end of the liquid pump 11 is connected to the second liquid tank 43 through the third valve 17, and the liquid outlet end of the liquid pump 11 communicates with the liquid inlet of the mixer 2. The third valve 17 functions as a liquid switch to control the pumping of liquid from the second liquid tank 43. When the third valve 17 is opened, the liquid pump 11 can pump liquid from the second liquid tank 43. When it comes to the third valve 17, the liquid pump 11 cannot pump liquid from the second liquid tank 43. The flow sensor 12 is disposed between the liquid outlet end of the liquid pump 11 and the liquid inlet of the mixer 2.

[0068] Moreover, the main control unit is electrically connected to the liquid pump 11 and the flow sensor 12 simultaneously. This enables the main control unit to obtain the pumping flow rate of the liquid pump 11 in real time through the flow sensor 12, and then adjust the working state of the liquid pump 11. That is, when the pumping flow rate meets the requirements, the main control unit controls the liquid pump 11 to stop operating. When the pumping flow rate does not meet the requirements, the main control unit controls the liquid pump 11 to continue operating.

[0069] Furthermore, in this alternative embodiment, the heater 13 is disposed in the second liquid tank 43. The heater 13 can heat the liquid, and then the liquid pump 11 outputs the heated liquid to the mixer 2. And, along the liquid flow direction, the temperature detector 14 is disposed downstream of the heater 13 for detecting the temperature of the pumped liquid. Regarding the type of the temperature detector 14, the temperature detector 14 can be a temperature sensor, an infrared sensor, a thermal resistor, a temperature detection probe, etc. Of course, this embodiment is only an example of the type of the temperature detector 14, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0070] Further, in an alternative embodiment, a sealing member is detachably connected to one end of each second liquid injection pipeline 44 away from the second liquid tank 43. The sealing member can be a sealing cover or a sealing plug and other sealing structures. Of course, this embodiment is only an example of the type of the sealing member, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0071] Furthermore, in an alternative embodiment, the liquid pumping assembly 1 further includes a check valve 15, and the check valve 15 is disposed at the liquid inlet end of the liquid pump 11. The check valve 15 can ensure the unidirectional conveyance of liquid to the liquid pump 11 and prevent backflow.

[0072] Of course, a pressure gauge can also be disposed downstream of the liquid pump to monitor the pressure of the liquid after pumping.

[0073] Further, in an optional embodiment, the temperature adjustment device further includes a display screen 8, and the display screen 8 is electrically connected to the main control unit, and the display screen can display the temperature.

[0074] When it is necessary to adjust the temperature of the target liquid, the temperature value of the target liquid can be set by setting the temperature of the mixer 2. The liquid pumping assembly 1 pumps in the initial liquid, adjusts the starting temperature to the target temperature set by the liquid pumping assembly 1, and flows into the mixer 2 for mixing. In another embodiment, the initial liquid is first adjusted to the set target temperature, and then the liquid is pumped into the mixer 2 for mixing. The temperature detection component can monitor the temperature of the liquid on the transmission pipeline in real time. When it is found online that there is a deviation between the temperature of the mixed liquid and the target temperature value, the mixing ratio of the liquids at different temperatures is adjusted according to the monitored actual temperature value, so that the temperature of the mixed liquid approaches the target temperature. This process involves the adjustment of the liquid flow rate or the fine adjustment of the mixing ratio of the liquids at different temperatures. If the final liquid does not reach the target temperature, the liquid returns to the first liquid tank 41 or the second liquid tank 43 via the return pipeline 5. If the target temperature is reached, the liquid is output outward via the liquid outlet pipeline 3.

[0075] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
