Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more specifically, to a small cleaning fluid heating device. Background Technology

[0002] The cleaning process for electronic components is crucial in electronic manufacturing and assembly, directly affecting the quality, reliability, and lifespan of the components. Cleaning can remove various contaminants remaining from the manufacturing process, such as flux, oil, particulate matter, and oxides. For some critical components, it is necessary to heat the cleaning agent to a specific temperature range to ensure good cleaning results.

[0003] In existing technologies, heating cleaning agents typically involves heating the agent uniformly in a container until it reaches a suitable temperature before use. However, this method requires heat preservation of the cleaning agent; otherwise, its temperature will drop. This approach is energy-intensive and may waste the cleaning agent, failing to provide immediate access. An instantaneous heater could be considered, containing an internal chip board to control the heating temperature. However, instantaneous heaters also require a power supply, resulting in numerous internal components and cables, messy wiring, poor component connection stability during use, and a relatively large heater size due to the need to secure various components.

[0004] Therefore, it is necessary for the inventors to design a new small cleaning fluid heating device to overcome the above problems. Summary of the Invention

[0005] The main objective of this application is to provide a small cleaning fluid heating device to solve the problems of poor stability during use caused by the large size of the heater and messy wiring in related technologies.

[0006] To achieve the above objectives, this application provides a small cleaning fluid heating device, including a mounting frame. A heating tube is fixedly mounted in the mounting frame. One end of the heating tube is fixedly connected to a liquid inlet, and the other end is fixedly connected to a liquid outlet. Both ends of the heating tube are connected to the positive and negative terminals of a power supply via cables, respectively. A clamping plate is fixedly mounted in the middle of the heating tube, and the middle section of the cable is clamped and fixed to the heating tube by the clamping plate. A circuit board is fixedly mounted at the bottom of the mounting frame, and the middle section of the cable is connected in series with the circuit board. A temperature regulating device is also fixedly mounted between the heating tube and the circuit board.

[0007] Optionally, the temperature regulating device includes a flow meter and a temperature sensor. The flow meter is fixedly installed at the liquid inlet and electrically connected to the circuit board, and the temperature sensor is fixedly installed on the outer wall of the heating tube and electrically connected to the circuit board.

[0008] Optionally, the temperature sensor is pressed against the outer wall of the heating tube by the clamping plate.

[0009] Optionally, the shaft segment where the heating tube mates with the clamping plate is flat.

[0010] Optionally, the clamping plate is fixedly connected to the mounting frame by bolts.

[0011] Optionally, a heat-insulating sleeve is fixedly provided between the clamping plate and the heating tube, and the cable passes through the heat-insulating sleeve.

[0012] Optionally, the outer wall of the mounting frame is also fixedly provided with several clamps for cable routing.

[0013] Optionally, the mounting frame is further fitted with an outer shell, and the liquid inlet and the liquid outlet penetrate the outer shell.

[0014] Optionally, a rheostat is also connected in series on the cable, and the rheostat is pressed against the heating tube by a clamping plate.

[0015] The small cleaning fluid heating device provided by this utility model has the following advantages compared with the prior art:

[0016] By connecting the circuit board, temperature control device, and heating element in series with a cable and fixing them to the heating element, and pressing the cable to the heating element with a clamping plate, the internal components of this device are compact, the wiring is clear, the stability during use is better, and the size can be controlled to be relatively small.

[0028] like Figures 1 to 3As shown, a small cleaning fluid heating device includes a mounting frame 1, in which a heating tube 2 is fixedly installed. One end of the heating tube 2 is fixedly connected to a liquid inlet 3, and the other end is fixedly connected to a liquid outlet 4. The two ends of the heating tube 2 are also connected to the positive and negative terminals of a power supply respectively via cables 12. A clamping plate 5 is fixedly installed in the middle of the heating tube 2, and the middle section of the cable 12 is clamped and fixed to the heating tube 2 by the clamping plate 5. A circuit board 6 is fixedly installed at the bottom of the mounting frame 1, and the middle section of the cable 12 is connected in series with the circuit board 6. A temperature regulating device is also fixedly installed between the heating tube 2 and the circuit board 6.

[0029] Specifically, the cleaning agent flows into the heating tube 2 from the inlet 3 and out of the outlet 4. The two ends of the heating tube 2 are connected to the positive and negative terminals of the power supply, respectively. When energized, the heating tube 2 acts as a heating element to heat the cleaning agent within it. The circuit board 6 is used to mount control components and electrically connect to the temperature control device to regulate the temperature of the heating tube 2. In this embodiment, the cable 12 connects the circuit board 6, the heating tube 2, and the temperature control component in series. Although the cable 12 is relatively long, its middle section is pressed down by the clamping plate 5, ensuring stable wiring within the mounting frame 1 and preventing loosening due to shaking of the entire device during use. This embodiment, by connecting the circuit board 6, the temperature control device, and the heating tube 2 in series via the cable 12 and fixing them to the heating tube 2, while simultaneously pressing the cable 12 down to the heating tube 2 with the clamping plate 5, results in a compact internal component layout, clear wiring, better stability during use, and a relatively small overall size.

[0030] The temperature regulation device includes a flow meter 7 and a temperature sensor 8. The flow meter 7 is fixedly installed at the liquid inlet 3 and electrically connected to the circuit board 6. The temperature sensor 8 is fixedly installed on the outer wall of the heating tube 2 and electrically connected to the circuit board 6. Specifically, the flow meter 7 detects the volume of the cleaning agent and adjusts the heating power to ensure the cleaning agent reaches the required temperature. The temperature sensor 8 detects whether the heating tube 2 has reached a suitable temperature and feeds back to the circuit board 6 to further control the power of the heating tube 2. The specific control method is not described in detail here.

[0031] The temperature sensor 8 is pressed against the outer wall of the heating tube 2 by the clamping plate 5. Specifically, conventional temperature sensors 8 require screws or other fasteners for fixation, thus taking up relatively much space. However, in this application, the clamping plate 5 is used for clamping, reducing the use of screws and other fasteners, thereby making the structure more compact and smaller in size.

[0032] The shaft segment where the heating tube 2 mates with the clamping plate 5 is flat. Specifically, to ensure the clamping effect of the cable 12 and the detection accuracy of the temperature sensor 8, the flat segment allows for a closer fit.

[0033] The clamping plate 5 is fixedly connected to the mounting frame 1 by bolts. Specifically, in this embodiment, at least the clamping plate 5 only needs to be connected to the mounting frame 1 by bolts, which greatly reduces the use of fasteners and reduces the size.

[0034] A heat-insulating sleeve 9 is fixedly installed between the clamping plate 5 and the heating tube 2, and the cable 12 passes through the heat-insulating sleeve 9. Specifically, in order to prevent the high temperature of the heating tube 2 from damaging the cable 12, the heat-insulating sleeve 9 is installed to protect the cable 12.

[0035] The outer wall of the mounting frame 1 is also fixedly provided with several clamps 10 for routing the cable 12. Specifically, when the cable 12 is connected to both ends of the heating tube 2, the clamps 10 can be used to limit the path of the cable 12 to prevent the cable 12 from becoming loose.

[0036] The mounting frame 1 is further fitted with an outer shell, not shown in the figure, through which the liquid inlet 3 and the liquid outlet 4 penetrate. Specifically, a structure for easy manual handling of the mounting frame 1 is provided on the outside of the mounting frame 1 to protect the internal electronic components. The shape of the outer shell is not limited here; any shape that can enclose the mounting frame 1 can be used.

[0037] A variable resistor 11 is also connected in series on the cable 12, and the variable resistor 11 is pressed onto the heating tube 2 by a clamping plate 5. Specifically, the circuit board 6 controls the heating power of the heating tube 2 by controlling the resistance value of the variable resistor 11, and pressing the variable resistor 11 with the clamping plate 5 is also for the purpose of compact structure and miniaturization.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
