Description

Technical Field

[0001] This utility model belongs to the field of water bath technology, specifically relating to a double-layer constant temperature water bath. Background Technology

[0002] Water baths have a wide range of applications. In the calibration of hemodialysis device testing instruments, conductivity and pH calibration need to be performed in a constant-temperature water bath, requiring a constant temperature of 25℃ and temperature fluctuations of less than ±0.1℃. However, in actual operation, when the external temperature is too high, the water absorbs the external heat, making it difficult to maintain a constant temperature inside the water bath. Conventional water baths with added refrigeration systems often use compressors for cooling, resulting in larger size and more noise, which is not conducive to integration with other systems in the hemodialysis device testing and calibration device. In addition, existing water baths have heating or liquid supply pipelines inside, making their internal structure complex and hindering the testing and calibration operations of the hemodialysis device testing instrument. Utility Model Content

[0003] The purpose of this invention is to provide a double-layer constant temperature water bath. It uses a double-layer structure with an inner pot spaced apart inside the outer pot. A circulation component and a temperature control component are installed between the inner and outer pots. The outlet pipe of the circulation component is connected to the inner pot, and the inlet pipe is connected to the inside of the outer pot. The heating and cooling elements in the temperature control component heat or cool the liquid in the outer pot, and then pump it into the inner pot through the circulation pump of the circulation component for temperature regulation, keeping the liquid temperature in the inner pot constant. Furthermore, the inner pot has no complex piping, facilitating the testing and calibration of the hemodialysis device detector.

[0004] This utility model is achieved through the following technical solution:

[0005] A double-layer constant temperature water bath includes an outer pot, an inner pot, a circulation component, and a temperature control component. The inner pot is smaller than the outer pot and is disposed inside the outer pot, spaced apart from the inner surface of the outer pot. The outer pot is taller than the inner pot. Multiple support members are disposed inside the outer pot, and the inner pot is mounted on the support members. The temperature control component is disposed on the outer pot, and the circulation component is disposed between the inner and outer pots. The circulation component and the temperature control component cooperate to circulate the liquid in the outer and inner pots and regulate the temperature of the liquid in the inner pot.

[0006] Furthermore, the inner pot has multiple overflow holes spaced apart on its side wall, and these overflow holes are located on the same horizontal plane.

[0007] Furthermore, the circulation assembly includes a circulation pump, an inlet pipe, and an outlet pipe. The circulation pump is located outside the outer pot, the inlet pipe passes through the outer pot and communicates with both the circulation pump and the interior of the outer pot, and the outlet pipe passes through the outer pot and communicates with both the circulation pump and the inner pot.

[0008] Furthermore, one end of the liquid inlet pipe located inside the outer pot is positioned below the inner pot and between the outer pot and the inner pot.

[0009] Furthermore, one end of the liquid outlet pipe located inside the outer pot is positioned below the inner pot and extends to the geometric center of the bottom of the inner pot, where it communicates with the inner pot.

[0010] Furthermore, the temperature control component includes at least one heating / cooling element, a heat sink, and a fan assembly. The bottom of the outer pot is provided with a mounting hole, the heating / cooling element is disposed at the mounting hole, the heat sink is disposed at the bottom of the heating / cooling element and abuts against the bottom of the outer pot, and the fan assembly is disposed below the heat sink.

[0012] In this invention, a double-layered pot structure is used, with an inner pot spaced apart inside the outer pot. A circulation component and a temperature control component are installed between the inner and outer pots. The liquid outlet pipe of the circulation component passes through the outer pot and connects to the inner pot, while the liquid inlet pipe connects to the inside of the outer pot. The heating and cooling elements in the temperature control component heat or cool the liquid in the outer pot, and then the liquid is pumped into the inner pot through the circulation pump of the circulation component for temperature regulation, so that the liquid temperature in the inner pot remains constant. Furthermore, there are no complicated pipes inside the inner pot, which facilitates the detection and calibration operation of the hemodialysis device detector. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] Example 1:

[0021] A double-layer constant temperature water bath, such as Figure 1 , Figure 2 and Figure 3 As shown, the system includes an outer pot 1, an inner pot 2, a circulation component, and a temperature control component. Both the inner pot 2 and the outer pot 1 are rectangular structures, with the inner pot 2 being smaller than the outer pot 1. The inner pot 2 is located inside the outer pot 1 and spaced apart from the inner surface of the outer pot 1. The height of the outer pot 1 is greater than the height of the inner pot 2. Four support members 3, which are columnar structures, are installed inside the outer pot 1. The four corners of the bottom of the inner pot 2 are connected to the support members 3, which support the inner pot 2 and prevent it from shifting. The temperature control component is located on the outer pot 1, and the circulation component is located between the inner pot 2 and the outer pot 1. The circulation component works in conjunction with the temperature control component to circulate the liquid in the outer pot 1 and the inner pot 2 and to regulate the temperature of the liquid in the inner pot 2. The inner pot 2 has multiple overflow holes 21 spaced apart on its side wall. The overflow holes 21 are located around the side wall of the inner pot 2 and are on the same horizontal plane. When there is too much liquid in the inner pot 2, the liquid will flow from the overflow holes 21 into the outer pot 1 for recirculation.

[0022] Example 2:

[0023] This embodiment, based on the above embodiments, further defines the circulation component and the temperature control component, such as... Figure 2 and Figure 4As shown, the circulation assembly includes a circulation pump 5, an inlet pipe 51, and an outlet pipe 52. The circulation pump 5 is located outside the outer pot 1. The inlet pipe 51 passes through the outer pot 1 and connects to both the circulation pump 5 and the interior of the outer pot 1. The outlet pipe 52 passes through the outer pot 1 and connects to both the circulation pump 5 and the inner pot 2. One end of the inlet pipe 51 inside the outer pot 1 is positioned below the inner pot 2 and between the outer pot 1 and the inner pot 2. The inlet pipe 51 has a two-way connector between the outer pot 1 and the inner pot 2. Each inlet of the two-way connector is close to a heating / cooling element 4, thereby enabling the liquid near the heating / cooling element 4 to be circulated. The liquid is drawn into the inner pot 2. One end of the outlet pipe 52, located inside the outer pot 1, is positioned below the inner pot 2 and extends to the geometric center of the bottom of the inner pot 2, communicating with it. The temperature control assembly includes two heating / cooling elements 4, one heat sink 6, and a fan assembly. The bottom of the outer pot 1 has two mounting holes 11. The heating / cooling elements 4 are fixed to the outer pot 1 at the mounting holes 11 with bolts. The heat sink 6 is located at the bottom of the heating / cooling elements 4 and abuts against the bottom of the outer pot 1. The fan assembly includes four cooling fans 7, all positioned below the heat sink 6 for heat dissipation. Other parts of this embodiment are the same as those in the previous embodiment and will not be repeated here.
