It generates suction through a built-in motor, which, together with a rotating brush head or roller brush, removes dust and stains from the floor. It is also equipped with a water tank and a mop to enable wet mopping. Some high-end models have functions such as self-cleaning, automatic recharging, and intelligent path planning, which can effectively improve cleaning efficiency.

[0003] A search revealed that Chinese utility patent CN215272501U discloses a noise-reducing body for a floor scrubber, comprising: a body and a positioning cylinder; a foam aluminum sleeve is installed inside the body, and a guide sleeve is provided at the lower end of the foam aluminum sleeve; the positioning cylinder is located inside the foam aluminum sleeve, and support fins are fixedly installed on the positioning cylinder, the support fins being spirally wound around the side wall of the positioning cylinder; the outer end of the support fins is fixed to the inner side wall of the foam aluminum sleeve, and a mounting frame is fixed to the inner end of the support fins; a motor is fixed on the mounting frame, and an impeller is fixed to the output end of the motor, located in the guide sleeve; an end cap is provided on the upper part of the body of the foam aluminum sleeve, and the end cap has an exhaust hole. When airflow passes through the gap between the foam aluminum sleeve and the positioning cylinder, the noise generated is absorbed by the porous structure of the foam aluminum sleeve, achieving a noise reduction effect.

[0004] However, the above design has a vent hole on the end cap, which causes the noise generated during operation to spread outward directly through the vent hole, making it prone to noise. Therefore, it has defects in use and needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a noise-reducing body to solve the problem of noise spreading outward through the exhaust port.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a noise-reducing housing, comprising a shell, wherein a drive motor is mounted inside the shell via a connecting frame, the connecting frame includes a heat-conducting ring plate sleeved on the surface of the drive motor, and a plurality of heat dissipation fins arranged at equal intervals are fixedly connected to the heat-conducting ring plate, the shell has an opening, and the plurality of heat dissipation fins pass through the opening and extend to the top of the shell, a heat dissipation coil is embedded inside the heat-conducting ring plate, and a liquid supply device for supplying cooling medium to the heat dissipation coil is installed inside the shell.

[0007] Preferably, a mounting plate is fixedly connected to the heat-conducting ring plate, and the mounting plate has a plurality of mounting holes. The mounting plate is mounted on the housing by bolts, and each bolt is located inside the mounting hole.

[0008] Preferably, the liquid supply device includes a liquid storage box fixedly connected inside the housing, a pump body is installed inside the liquid storage box, the output end of the pump body passes through the liquid storage box and is fixedly connected to the input end of the heat dissipation coil, and the output end of the heat dissipation coil passes through the liquid storage box and extends into its interior.

[0011] Preferably, a maintenance plate may be installed on the left side of the housing, and a connector may be installed on the right side of the housing.

[0012] Preferably, the interior of the housing is filled with sound-insulating cotton.

[0013] Preferably, a protective frame is fixedly connected to the upper end face of the housing, and the heat dissipation fins are disposed inside the protective frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, by designing the housing as a fully enclosed structure, effectively blocks the mechanical noise generated during the operation of the drive motor, thus avoiding the sound leakage problem caused by traditional heat dissipation vents and improving noise reduction. Through the design of a heat-conducting ring plate and heat dissipation fins, the heat generated during operation is conducted directly to the heat dissipation fins on top of the housing by the heat-conducting ring plate directly contacting the drive motor surface. This allows for heat dissipation through external airflow, eliminating the need for openings in the housing. Furthermore, the heat dissipation coil is embedded within the heat-conducting ring plate, and the cooling medium is circulated by a pump, carrying heat to the liquid storage box for dispersion, further ensuring heat dissipation. The synergistic use of these two heat dissipation methods achieves good heat dissipation efficiency without the need for housing vents, resolving the conflict between airtightness and heat dissipation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 As shown, a noise-reducing housing includes a shell 1. A drive motor 2 is mounted inside the shell 1 via a connecting frame. The connecting frame includes a heat-conducting ring plate 8 fitted onto the surface of the drive motor 2. A plurality of equidistant heat dissipation fins 11 are fixedly connected to the heat-conducting ring plate 8. An opening is provided on the shell 1, through which the heat dissipation fins 11 pass and extend to the top of the shell 1. A mounting plate 9 is fixedly connected to the heat-conducting ring plate 8, and a plurality of mounting holes 10 are provided on the mounting plate 9. The mounting plate 9 is mounted to the shell 1 by bolts, with each bolt located inside a mounting hole 10. A protective frame 12 is fixedly connected to the upper surface of the shell 1, and the heat dissipation fins 11 are located inside the protective frame 12. Sound-insulating cotton 18 is filled inside the shell 1.

[0024] The housing 1 serves to support, protect, and insulate the sound. The sound-absorbing cotton 18 inside effectively absorbs the mechanical vibration and electromagnetic noise generated by the drive motor 2 during operation, preventing sound leakage and ensuring that the equipment operates in a low-noise environment. The housing 1 is designed to be enclosed, thus avoiding the noise leakage problem caused by traditional open-vent heat dissipation.

[0025] The connecting frame uses a heat-conducting ring plate 8 fitted onto the surface of the motor, which can not only stably support the drive motor 2, but also efficiently conduct the heat generated during its operation outward for heat dissipation. Multiple equidistant heat dissipation fins 11 are welded on the heat-conducting ring plate 8. These fins pass through the opening at the top of the housing 1 and can utilize the external airflow for heat dissipation.

[0026] It should be noted that the opening on the casing 1 only allows the heat dissipation fins 11 to pass through, without affecting its overall sealing. This ensures both heat dissipation efficiency and good sound insulation. The protective frame 12 protects the heat dissipation fins 11.

[0027] A heat dissipation coil 14 is embedded inside the heat-conducting ring plate 8, and a liquid supply device for supplying cooling medium to the heat dissipation coil 14 is installed inside the housing 1. The liquid supply device includes a liquid storage box 13 fixedly connected inside the housing 1, and a pump body 15 is installed inside the liquid storage box 13. The output end of the pump body 15 passes through the liquid storage box 13 and is fixedly connected to the input end of the heat dissipation coil 14. The output end of the heat dissipation coil 14 passes through the liquid storage box 13 and extends into its interior. A drain pipe 16 is fixedly connected to the liquid storage box 13. The other end of the drain pipe 16 passes through the housing 1 and extends to the outside of the housing 1. A sealing cap 17 is installed on the drain pipe 16.

[0028] Specifically, the pump body 15 pumps coolant from the reservoir 13 into the cooling coil 14. After absorbing heat from the heat-conducting ring plate 8, the high-temperature coolant can flow back to the reservoir 13 for natural cooling, forming a circulation. During use, it can quickly cool the drive motor 2 under high load conditions, preventing overheating failure. The drain pipe 16 and sealing cap 17 on the reservoir 13 facilitate the replacement or replenishment of the coolant, ensuring efficient heat dissipation during long-term use.

[0029] A chassis 4 is located at the bottom of the housing 1, and a cleaning frame 6 is mounted on the chassis 4. Two sets of rollers 5 are mounted on the chassis 4. A drive box 3 is installed inside the housing 1. The input end of the drive box 3 is fixedly connected to the output end of the drive motor 2, and the output end of the drive box 3 is fixedly connected to the input end of the chassis 4. A maintenance plate 7 can be installed on the left side of the housing 1, and a connector 19 is installed on the right side of the housing 1.

[0030] The chassis 4, located at the bottom of the housing 1, supports the entire machine structure. Two sets of casters 5 are mounted on it, allowing for flexible movement of the machine, suitable for scenarios requiring frequent repositioning. The drive box 3 connects the drive motor 2 and the chassis 4, transmitting power from the drive motor 2 to the casters 5 to enable machine movement. The cleaning frame 6, fixed to the chassis 4, collects dust or debris. An inspection plate 7 facilitates maintenance of internal components of the housing 1, while the connector 19 allows for modular expansion, enabling quick docking of the machine with other equipment.

[0031] Working principle: The housing 1 is a closed structure, and the drive motor 2 is completely enclosed inside the housing 1. The inside is filled with sound insulation cotton 18, which can effectively absorb the mechanical vibration noise and electromagnetic noise generated by the motor during operation and reduce sound leakage. For the heat generated by the motor during operation, it can be transferred to the heat conduction ring plate 8 through surface contact. Multiple heat dissipation fins 11 are fixed on the heat conduction ring plate 8 and extend to the top of the housing 1, which can utilize the natural convection of external air to dissipate heat. Furthermore, the heat conduction ring plate 8 is also embedded with a heat dissipation coil 14. Coolant is drawn from the liquid storage box 13 through the pump body 15 and pumped into the heat dissipation coil 14, which can absorb the heat on the heat conduction ring plate 8 to ensure its stability during use. The drive motor 2 transmits power to the chassis 4 through the drive box 3, and the drive rollers 5 realize the movement of the machine body. The cleaning frame 6 can collect dust or debris.
