Description

Technical Field

[0001] This utility model specifically relates to a dual-inlet, single-outlet suction motor for a floor scrubber, belonging to the field of floor scrubber motor technology. Background Technology

[0002] The dual-inlet single-outlet suction motor of a floor scrubber is a relatively advanced motor design with unique structure and advantages. The dual-inlet single-outlet suction motor system usually includes a vacuum cleaner motor with a high-speed rotating fan at the front and a cooling fan at the rear, a motor bracket for mounting the front of the vacuum cleaner motor, a motor cover installed at the rear of the vacuum cleaner motor and assembled with the motor bracket, and a motor bracket sealing device located between the motor bracket and the motor cover to isolate the front and rear ends of the vacuum cleaner motor. When working, the vacuum cleaner motor rotates at high speed, driving the high-speed rotating fan to rotate at high speed. A negative pressure is generated at the front central air passage to form a vacuum, which in turn generates suction. Dry and wet air enter the front central air passage and are then discharged from the outer air outlet chamber along the outer edge of the high-speed rotating fan.

[0003] Although dual-inlet single-outlet suction motors have a heat dissipation design, if the floor scrubber is used in a poorly ventilated environment, or if the machine's heat dissipation vents are blocked, the motor may have difficulty dissipating heat, causing the temperature to rise. If the motor overheats and is not cooled down in time, it will be damaged and its lifespan will be reduced. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a dual-inlet, single-outlet suction motor for a floor scrubber. This motor effectively dissipates the heat generated during operation, keeping the motor temperature within a reasonable range. This slows down the aging of insulation materials and the rate of component damage, thereby extending the motor's lifespan. It also ensures that all internal components of the motor operate stably, maintaining the stability of the magnetic field and resistance, thus guaranteeing stable motor performance. This allows the motor to continuously provide stable suction and power, maintaining high efficiency, reducing energy consumption, and saving energy costs.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a dual-inlet single-outlet suction motor for a floor scrubber, comprising a motor body, the motor body being divided into upper and lower parts and connected by a side sealing strip, a side cover plate being provided on the outer side of the lower half of the motor body via a rotating rod, a limiting strip plate being fixedly provided at the bottom of the outer side of the side cover plate, an inner arc rod being rotatably provided at both ends of the inner side of the limiting strip plate, an arc sleeve being slidably sleeved at the end of the inner arc rod away from the limiting strip plate, and an arc sleeve being fixedly provided at the top of the inner wall of the motor body at the end of the arc sleeve away from the inner arc rod, and a closing baffle being snapped onto the left end of the motor body.

[0006] A power groove is provided in the middle of the inner wall of the bottom of the motor body. A hydraulic telescopic rod is fixedly installed at one end of the inner wall of the power groove, and a rotating frame is fixedly installed at the other end of the hydraulic telescopic rod. A transverse moving plate is rotatably installed at both ends of the inner wall of the rotating frame through a rotating rod. The end of the transverse moving plate away from the rotating frame is rotatably connected to the middle of the bottom of the inner wall of the side cover.

[0007] Preferably, the side sealing strip is set in an "H" shape, and the sealing strip is located between the upper and lower parts of the motor body. The inner wall of the side sealing strip is provided with an anti-slip layer. The "H" shaped side sealing strip is used to firmly fix the two parts of the motor body together.

[0008] Preferably, filter screens are provided on both sides of the lower half of the motor body. The filter screens are located inside the side groove of the motor body. The area of ​​the groove is the same as the area of ​​the side cover plate. A support frame is fixedly provided at the bottom of the motor body. By providing filter screens on both sides of the motor body, heat can be dissipated from both sides. At the same time, the screens can prevent dust and impurities from entering the interior, thus playing a filtering role.

[0009] Preferably, a support shaft is rotatably inserted into the middle of the transverse moving plate, and the two ends of the support shaft are fixedly set in the middle position of the inner wall of the power groove. There are two transverse moving plates, and one end of each of the two transverse moving plates is rotatably connected to the inner wall of the two side cover plates. One end of the transverse moving plate swings under the action of the hydraulic telescopic rod. Under the action of the support shaft, the movement trajectory of the transverse moving plate is restricted, so that the transverse moving plate can only make circular motion around the center of the support shaft.

[0010] Preferably, a heat dissipation plate is provided in the middle of the closed baffle, and a through filter groove is provided in the middle of the heat dissipation plate. Trapezoidal grooves are provided on both sides of the heat dissipation plate. Trapezoidal sliders are slidably provided on the inner wall of the trapezoidal grooves. A scraper strip is fixedly provided on the outer side of the trapezoidal slider. The brush layer on the inner side of the scraper strip is slidably connected to the outer side of the closed baffle. The heat inside the motor body is dissipated through the heat dissipation plate at one end, increasing the heat dissipation area. The scraper strip slides on the surface of the heat dissipation plate, effectively cleaning the dust adhering to the surface of the heat dissipation plate.

[0011] Preferably, the scraper strip is in two sets and has trapezoidal sliders at both ends. A return spring is provided between the two sets of trapezoidal sliders. The diameter of the return spring is smaller than the diameter of the grooves on both sides of the closed baffle. The return spring will promptly reset the trapezoidal sliders and the scraper strip in the middle after they have moved.

[0012] Preferably, there are two side covers, which are rotatably mounted on both sides of the motor body. The maximum rotation angle of the side covers is 60 degrees. After the side covers are rotated to a certain angle, the two sides of the motor body can be opened to facilitate internal heat dissipation.

[0013] The beneficial effects of this utility model are as follows: This dual-inlet, single-outlet suction motor for a floor scrubber features openable side covers on both sides of the motor body. When the motor's own heat dissipation is insufficient to meet the cooling requirements, the side covers are opened, allowing the heat inside the motor to dissipate through the open positions on both sides. Simultaneously, through-hole heat dissipation vents on both sides further enhance heat dissipation. Timely heat dissipation keeps the motor temperature within a reasonable range, slowing down the aging of insulation materials and the rate of component damage, thereby extending the motor's service life. Furthermore, a sliding scraper strip is provided at one end of the motor body to promptly remove surface dust, preventing impurities from clogging the heat dissipation points and preventing dust from entering the interior. This effectively prevents the motor's heat dissipation efficiency from being affected, avoiding a rapid rise in motor temperature due to ineffective heat dissipation. Attached Figure Description

The filter plates are located inside the side grooves of the motor body 1, and the area of ​​the grooves is the same as the area of ​​the side cover plate 10. A support frame 7 is fixedly installed at the bottom of the motor body 1. By providing filter plates on both sides of the motor body 1, heat can be dissipated from both sides, and the filter plates can also trap dust and impurities, thus achieving a filtering effect. The motor body 1 is divided into upper and lower parts, which are connected by a side sealing strip 2. The side sealing strip 2 is H-shaped and located between the upper and lower parts of the motor body 1. The inner wall of the side sealing strip 2 is provided with an anti-slip layer. The H-shaped side sealing strip 2 is used to tightly fix the two parts of the motor body 1 together and facilitate the disassembly and assembly of the motor body 1.

[0024] Two side covers 10 are mounted on the outer side of the lower half of the motor body 1 via a rotating rod. Each side cover 10 is rotatably mounted on one side of the motor body 1. The maximum rotation angle of each side cover 10 is 60 degrees. Rotating the side covers 10 to a certain angle allows the sides of the motor body 1 to open, facilitating internal heat dissipation. The through-type design of the side covers 10, when open, allows for rapid airflow from both sides, further enhancing heat dissipation. A limiting strip 9 is fixedly mounted at the bottom of the outer side of each side cover 10. Both ends of the inner side of the limiting strip 9 are rotatably mounted with an inner arc-shaped rod 8. An arc-shaped sleeve 11 is slidably fitted onto the end of the inner arc-shaped rod 8 furthest from the limiting strip 9. The end of the sleeve 11 away from the inner arc rod 8 is fixedly set on the top of the inner wall of the motor body 1. A closed baffle 4 is snapped on the left end of the motor body 1. A heat dissipation plate 6 is set in the middle of the closed baffle 4. A through filter groove is set in the middle of the heat dissipation plate 6. Trapezoidal grooves are set on both sides of the heat dissipation plate 6. Trapezoidal sliders are slidably set on the inner wall of the trapezoidal grooves. A scraper strip 3 is fixedly set on the outer side of the trapezoidal slider. The brush layer on the inner side of the scraper strip 3 is slidably connected to the outer side of the closed baffle 4. The heat inside the motor body 1 is dissipated through the heat dissipation plate 6 at one end, increasing the heat dissipation area. The scraper strip 3 slides on the surface of the heat dissipation plate 6, effectively cleaning the dust adhering to the surface of the heat dissipation plate 6.

[0025] The scraper strip 3 consists of two sets with trapezoidal sliders at both ends. A return spring 5 is installed between the two sets of trapezoidal sliders. The diameter of the return spring 5 is smaller than the diameter of the sliding grooves on both sides of the closed baffle 4. The return spring 5 will promptly reset the trapezoidal sliders and the scraper strip 3 in the middle after they have moved. When the scraper strip 3 moves, it will scrape off the dust on the surface to prevent it from affecting the heat dissipation effect.

[0026] A power groove 12 is provided in the middle of the bottom inner wall of the motor body 1. A hydraulic telescopic rod 14 is fixedly provided at one end of the inner wall of the power groove 12, and a rotating frame 16 is fixedly provided at the other end of the hydraulic telescopic rod 14. A transverse moving plate 15 is rotatably provided at both ends of the inner wall of the rotating frame 16 via a rotating rod.

The two ends of the support shaft 13 are fixedly provided in the middle of the inner wall of the power groove 12. There are two transverse moving plates 15. One end of each transverse moving plate 15 is rotatably connected to the inner wall of the two side cover plates 10. One end of the transverse moving plate 15 swings under the action of the hydraulic telescopic rod 14. Under the action of the support shaft 13, the movement trajectory of the transverse moving plate 15 is restricted, so that the transverse moving plate 15 can only make circular motion around the center of the support shaft 13.
