[0018] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0019] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.
[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0021] Reference Figures 1 to 5 This utility model discloses a heated washing pump with temperature control protection function, including a motor unit 10, a pump body 20, and a heating unit 30. The motor unit 10 provides power to drive the liquid. The pump body 20 is connected to the motor unit 10 and drives the liquid. The heating unit 30 is disposed on the pump body 20. The heating unit 30 includes a heating ring 31 and a temperature control device 32. The heating ring 31 is disposed in the pump body 20. The temperature control device 32 is disposed on the pump body 20 and electrically connected to the heating ring 31. The heating ring 31 is used to heat the liquid in the pump body 20. The temperature control device 32 is used to detect the temperature of the liquid in the pump body 20 and control the opening or closing of the heating ring 31.
[0022] Understandably, the temperature control device 32 monitors the liquid temperature inside the pump body 20 in real time and dynamically controls the opening or closing of the heating ring 31 to avoid thermal damage to the pump housing 21 and internal seals caused by overheating of the liquid. The pump body 20 includes a pump housing 21, a motor end sealing cover 22, and a pump cavity 23. The pump housing 21 is fitted onto the motor part 10, the motor end sealing cover 22 is located at the end of the pump housing 21 near the motor part 10, and the pump cavity 23 is the cavity formed by the pump housing 21 and the motor end sealing cover 22. The heating ring 31 is set close to the inner wall of the pump housing 21.
[0023] Understandably, the pump chamber 23, formed by the pump housing 21 and the motor end sealing cover 22, provides a sealed flow channel for the liquid, effectively preventing liquid leakage. The arrangement of the heating ring 31 close to the inner wall of the pump housing 21 allows heat to be directly transferred to the liquid flowing through the pump chamber 23. The heat can be conducted through the pump housing, greatly improving the liquid heating effect.
[0024] Reference Figures 1 to 5 The temperature control device 32 includes a power interface 321 and a signal interface 322. The power interface 321 is configured as the interface for connecting the heating ring 31 to a power source. The signal interface 322 is configured as the interface for connecting the heating ring 31 to a temperature sensor, which is connected to the power source controller.
[0025] It is worth noting that in some embodiments of this utility model, the signal interface 322 is configured as the interface between the heating ring 31 and the pressure sensor, and the pressure sensor is connected to the power supply controller.
[0026] Understandably, power interface 321 provides an independent power supply path for heating ring 31, ensuring stable operation of the heating function and avoiding power fluctuations caused by circuit interference. Signal interface 322, through the dual signal transmission of integrated temperature and pressure sensors, enables the controller to acquire real-time liquid state data within pump chamber 23 and automatically adjust the operating state of heating ring 31 according to preset thresholds. When an abnormal temperature increase or pressure exceeding the safe range is detected, the controller can immediately cut off the power supply to heating ring 31 and trigger a protection mechanism to prevent damage to the equipment due to overload or dry burning, thus improving the safety and reliability of the system.
[0027] Reference Figures 1 to 5 The heating unit 30 also includes a water-proof membrane 33. The water-proof membrane 33 is disposed in the pump chamber 23. The water-proof membrane 33 is attached to the inner ring of the heating ring 31, and the water-proof membrane 33 is configured to prevent water in the pump chamber 23 from contacting the heating ring 31.
[0028] The water-resistant membrane 33 physically isolates the liquid within the pump chamber 23 from the heating ring 31, effectively preventing short circuits or oxidation corrosion of the heating element caused by direct liquid contact. Made of a high-temperature resistant material with excellent insulation properties, the water-resistant membrane 33 can operate stably for extended periods in high-temperature environments while allowing efficient heat transfer to the liquid. This design not only extends the service life of the heating ring 31 but also avoids safety hazards caused by liquid seepage into the heating area, significantly improving the overall safety of the equipment.
[0029] Reference Figures 1 to 5 The heating unit 30 also includes a sealing ring 34. The sealing ring 34 is disposed in the pump chamber 23. The sealing ring 34 is disposed at the ends of the water-proof membrane 33 and the heating ring 31. The sealing ring 34 is used to seal the ends of the water-proof membrane 33 and the heating ring 31.
[0030] There are two sets of sealing rings 34. The two sets of sealing rings 34 respectively seal the two ends of the heating ring 31 and the contact points with the water-proof membrane 33.
[0031] Two sets of sealing rings 34 form a double sealing barrier at the ends of the water-proof membrane 33 and the heating ring 31, respectively, completely preventing the risk of liquid seeping into the heating area from the connection gap. The sealing rings 34 are made of an elastic material, capable of adapting to the slight deformation of the pump body 20 due to temperature changes, ensuring sealing performance under long-term use. This redundant sealing design significantly reduces the possibility of leakage due to single-point seal failure, enhancing the stability and reliability of the equipment under high pressure or high temperature fluctuation conditions.
[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0033] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
