This makes it difficult to control the flow rate and speed of the liquid supply, resulting in inaccurate liquid supply and waste.

[0005] To achieve the above objectives, this utility model provides a DC motor liquid supply device, including a fixed plate and a liquid supply assembly. The liquid supply assembly includes a controller, a first connecting pipe, a second connecting pipe, a flexible coupling, a motor, a gear pump, and a solenoid valve.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] Please see Figures 1-2 , Figure 1 This is a structural diagram of a DC motor liquid supply device according to the present invention. Figure 2 This is a cross-sectional schematic diagram of a DC motor liquid supply device according to the present invention.

[0018] This utility model provides a DC motor liquid supply device, comprising a fixing plate 101 and a liquid supply assembly 102. The liquid supply assembly 102 includes a controller 103, a first connecting pipe 104, a second connecting pipe 105, a flexible coupling 106, a motor 107, a gear pump 108, a solenoid valve 109, a filter nozzle 110, a one-way valve 111, a sleeve 112, a telescopic rod 113, a mounting plate 114, an internally threaded pipe 115, an externally threaded rod 116, a fixing bolt 117, and a rubber plate 118. This solution addresses the problem in existing coolant supply systems where the pump directly extracts the cooling liquid, which then flows through pipes to the nozzle for spraying. This makes it difficult to control the flow rate and speed of the liquid supply, leading to inaccurate supply and waste.

[0019] In this embodiment, the motor 107 is detachably connected to the fixing plate 101 and is located on top of the fixing plate 101. The gear pump 108 is mounted on top of the fixing plate 101. The output end of the motor 107 is connected to the gear pump 108 via the flexible coupling 106. The first connecting pipe 104 communicates with the inlet of the gear pump 108 and is located on one side of the gear pump 108. The second connecting pipe 105 communicates with the outlet of the gear pump 108 and is located at one end of the gear pump 108. The solenoid valve 109 is connected to the second connecting pipe 105 and is located on one side of the second connecting pipe 105. The controller 103 is fixedly connected to the fixing plate 101 and is located on the outside of the fixing plate 101. The fixing plate 101 is used to mount the motor 107 and the gear pump 108. The gear pump 108 is driven by the motor 107 to pump liquid. The controller 103 controls the motor 107 to control its speed, thereby controlling the pumping volume and inlet speed of the gear pump 108. The gear pump 108 and the motor 107 are connected by the flexible coupling 106, which can reduce vibration transmission and reduce operating noise. The first connecting pipe 104 is used for liquid inlet, and the second connecting pipe 105 is used for liquid outlet. The solenoid valve 109 can control the opening and closing of the second connecting pipe 105, thereby further controlling the liquid flow rate. This solves the problem of existing coolant supply systems, where the coolant is directly pumped out of the pump body and then sprayed through pipes into the nozzles, making it difficult to control the flow rate and speed of the supply, resulting in inaccurate supply and waste.

[0020] The liquid supply assembly 102 further includes a filter nozzle 110 and a one-way valve 111. The filter nozzle 110 is connected to the first connecting pipe 104 and is located on one side of the first connecting pipe 104. The one-way valve 111 is connected to the second connecting pipe 105 and is located on one side of the second connecting pipe 105. The filter nozzle 110 is used to filter impurities entering the gear pump 108 to prevent clogging. The one-way valve 111 prevents water pumped out by the gear pump 108 from flowing back into the gear pump 108.

[0021] Secondly, the liquid supply assembly 102 also includes a sleeve 112, a telescopic rod 113, and a mounting plate 114. The sleeve 112 is fixedly connected to the fixed plate 101 and is located at the bottom of the fixed plate 101. The telescopic rod 113 is detachably connected to the sleeve 112 and is located on one side of the sleeve 112. The mounting plate 114 is connected to the telescopic rod 113 and is located at the bottom of the telescopic rod 113. The device is installed through the mounting plate 114, and the distance between the mounting plate 114 and the fixed plate 101 is adjusted by the telescopic rod 113, thereby adjusting the height position of the device.

[0022] Furthermore, the telescopic rod 113 includes an internally threaded tube 115 and an externally threaded rod 116. The externally threaded rod 116 is detachably connected to the sleeve 112 and is located on one side of the sleeve 112. The internally threaded tube 115 is threadedly connected to the externally threaded rod 116 and is located outside the externally threaded rod 116. The mounting plate 114 is fixedly connected to the internally threaded tube 115 and is located at the bottom of the internally threaded tube 115. After adjusting the length by threading the externally threaded rod 116 to the internally threaded tube 115, it is slidably inserted into the sleeve 112, and then the sleeve 112 and the externally threaded rod 116 are fixed by bolts.

[0023] Finally, the liquid supply assembly 102 also includes a fixing bolt 117 and a rubber plate 118. The fixing bolt 117 is threadedly connected to the mounting plate 114 and is located on one side of the mounting plate 114. The rubber plate 118 is fixedly connected to the mounting plate 114 and is located at the bottom of the mounting plate 114. The rubber plate 118 is used to increase the bottom elasticity of the mounting plate 114, so that the mounting plate 114 has a certain buffer elasticity. The fixing bolt 117 is used to connect the mounting plate 114 to the placement surface.

[0024] In the DC motor liquid supply device of this utility model, the fixing plate 101 is used to install the motor 107 and the gear pump 108. The motor 107 drives the gear pump 108 to pump liquid. The controller 103 controls the motor 107 to control its speed, thereby controlling the pumping volume and inlet speed of the gear pump 108. The gear pump 108 and the motor 107 are connected by the flexible coupling 106, which can reduce vibration transmission and reduce operating noise. The first connecting pipe 104 is used for liquid inlet, and the second connecting pipe 105 is used for liquid outlet. The solenoid valve 109 can control the opening and closing of the second connecting pipe 105, thereby further controlling the liquid flow rate. This solves the problem of existing coolant supply systems, where the coolant is directly pumped out by the pump body and then enters the nozzle through the pipe for spraying, making it difficult to control the flow rate and speed of the liquid supply, resulting in inaccurate liquid supply and waste.

[0025] The above-disclosed embodiments are merely preferred embodiments of the DC motor liquid supply device of this utility model, and should not be construed as limiting the scope of this utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this utility model are still within the scope of this utility model.
