Description

Technical Field

[0001] The present application relates to the technical field of floor scrubbers, and in particular to a floor scrubber and a base assembly. Background Art

[0002] With the development of economy and the progress of society, people will put forward more and more requirements for smart home appliances, such as practicality, speed, simplicity, environmental protection, safety, etc. Multifunctional smart home appliances will be recognized by users.

[0003] The existing floor scrubber has a matching charging stand for charging. When the floor scrubber is placed on the charging stand, the roller brush can be self-cleaned. However, after the roller brush is self-cleaned, the roller brush is still wet, which is easy to breed bacteria and produce odor, and is difficult to keep dry and clean. In addition, there are many water stains on the outer casing of the floor scrubber and the charging stand, which affects hygiene. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a floor scrubber, which is used to solve the problem that the roller brush of the existing floor scrubber cannot be kept dry and clean after self-cleaning of the roller brush.

[0005] The present application provides a floor scrubber, comprising:

[0006] The main unit comprises a housing and a roller brush, wherein the roller brush can rotate around its own axis and is arranged inside the housing;

[0007] The base is provided with a groove; the shell is detachably connected to the base, the shell is used to cover the groove to form a cleaning cavity, and the roller brush is located in the cleaning cavity;

[0008] A heating mechanism is arranged on the base; at least a part of the heating mechanism is located in the groove and is used to transfer heat toward the roller brush.

[0009] In the above-mentioned floor scrubber, the roller brush can be used to clean the floor. After the floor scrubber is used, it needs to be cleaned. The roller brush after cleaning is wet and contains a lot of water. By arranging a heating mechanism on the base, the part of the heating mechanism located in the groove is used to transfer heat to the roller brush to heat and dry the roller brush. A part of the heating mechanism is directly located in the groove, which can directly and effectively heat the roller brush, and the heating and drying effect is better; and when the roller brush rotates, the roller brush can be heated evenly, not only the air temperature between the heating mechanism and the roller brush is high, but the rotating roller brush can drive the air temperature around the roller brush to rise, so that the temperature in the entire cleaning chamber rises, thereby further improving the drying effect of the roller brush; wherein, the roller brush can rotate at a low speed, so that any side of the roller brush can be fully heated when passing through the heating mechanism.

[0010] In one embodiment, the cleaning chamber has a vent, and the vent is used to communicate with the outside world. When the heating mechanism heats and dries the roller brush, the rotation of the roller brush drives air flow, the air temperature around the roller brush rises, and the hot and humid air with moisture in the cleaning chamber can be discharged from the vent. After the hot and humid air is discharged, dry cold air can enter the cleaning chamber from the vent, and the entering dry cold air is heated to ensure the balance of air pressure in the cleaning chamber.

[0011] In one embodiment, the two sides of the shell are provided with a mounting shell part respectively, one end of the roller brush is connected to one mounting shell part, and the other end of the roller brush is connected to another mounting shell part, and there is a gap between at least one mounting shell part and the base, and the gap forms the vent. The hot and humid air is discharged through the gap to avoid discharging too much hot air at once; the air that is slightly colder tends to sink downward, and the air with moisture tends to sink downward. When the gap is located at the bottom of the cleaning chamber, the air with low temperature and moisture that is not good for drying effect will be discharged from the vent formed by the gap, that is, the hot humid air is discharged from the vent, and the humid air and dry air with higher temperature continue to be used to heat and dry the roller brush.

[0012] In one embodiment, the heating mechanism includes at least one of a resistance heating element, an infrared heating element and an induction heating element, and the heating mechanism is arranged in the groove, that is, the heating mechanism can be a resistance heating element, an infrared heating element, or an induction heating element, or the heating mechanism is composed of two or three of the resistance heating element, the infrared heating element and the induction heating element. The heating mechanism is arranged in the groove to directly heat the roller brush, and at least one of the resistance heating element, the infrared heating element and the induction heating element directly releases heat to the roller brush to dry the roller brush.

[0013] In one embodiment, the housing has a bottom end surface, the bottom end surface is provided with an opening connected to the inside of the housing, and part of the roller brush is exposed in the opening; the bottom surface of the groove is provided with a receiving groove connected to the groove; when the housing is connected to the base, the bottom end surface contacts the bottom surface of the groove, and the part of the roller brush exposed in the opening is received in the groove and the receiving groove; the heating mechanism is arranged on the side wall surface or the bottom surface of the groove. When the housing is in the groove, the bottom end surface of the housing contacts the bottom surface of the groove, and since the roller brush is exposed inside the housing, that is, protrudes relative to the bottom end surface, the receiving groove arranged on the bottom surface of the groove can accommodate the protruding part of the roller brush, so as to facilitate the matching between the host and the base; in addition, since the receiving groove matches the exposed part of the roller brush, and the receiving groove is arranged on the bottom surface of the groove, the receiving groove can be used to store water, and the water on the side wall surface and the bottom surface of the groove can flow into the receiving groove, so the heating mechanism arranged on the wall surface or the bottom surface of the groove will not be immersed in water, thereby avoiding affecting the heating of the heating mechanism.

[0014] In one embodiment, the heating mechanism includes a heating plate and a heat source, the heat source is connected to the heating plate, the heating plate is arranged in the groove, and generates heat toward the roller brush. The heating plate is heated by the heat source, and the heated heating plate in the groove transfers heat to the roller brush in the cleaning chamber to heat and dry the roller brush in the cleaning chamber, and the rotating roller brush can drive hot air to fill the cleaning chamber.

[0015] In one embodiment, the heat source part includes at least one of a resistance wire, a PTC and a carbon film resistor, and the heating plate is directly and effectively heated by one or more of the resistance wire, the PTC and the carbon film resistor.

[0016] In one embodiment, the base is provided with an installation opening, which connects the groove and the outside world; the heating plate is connected to the base and seals the installation opening, one side of the heating plate faces the roller brush, and the heat source part is arranged on the side of the heating plate away from the roller brush, that is, the heat source part is located outside the cleaning chamber. Since the heating plate needs to be in the groove, and the heat source part will be corroded by water vapor in the groove, the heating plate is arranged at the position of the installation opening, so that one side of the heating plate faces the groove and the roller brush, and the other side of the heating plate faces the outside world, and the heat source part can be arranged on the side of the heating plate facing the outside world to avoid the heat source part being arranged in the groove and corroded by water vapor; the heating plate seals the installation opening to prevent water vapor from flowing out of the installation opening.

[0017] In one embodiment, the heating plate is embedded in the installation opening, and a sealing heat insulating component is arranged between the side of the heating plate and the inner wall of the installation opening, and the sealing heat insulating component is used for sealing, waterproofing and heat insulation to prevent water leakage and prevent the heating plate from melting the base.

[0018] In one of the embodiments, one side of the heating plate abuts against the roller brush.

[0019] In one of the embodiments, there is a gap between one side of the heating plate and the roller brush, so that the heating plate does not directly contact the roller brush and radiates heat to the roller brush, thereby heating not only the roller brush but also the air between the heating plate and the roller brush, thereby facilitating a rapid increase in the temperature in the cleaning chamber. Furthermore, the heating plate does not contact the roller brush, so when the roller brush is not rotating, the roller brush is prevented from being burned. When the roller brush is rotating, friction between the heating plate and the roller brush is prevented from affecting its rotation.

[0020] In one embodiment, the heating mechanism includes a circuit board and a heating lamp, the circuit board is electrically connected to the heating lamp, the heating lamp is arranged in the groove, and generates heat toward the roller brush.

[0021] In one embodiment, the circuit board is arranged on the side wall of the groove, and the heating lamp is arranged on the circuit board. In this way, the circuit board is directly arranged in the groove, and the heating lamp can be directly arranged on the circuit board to avoid wiring, such as welding the heating lamp on the circuit board. Moreover, since the circuit board is arranged on the side wall of the groove, the circuit board is prevented from being immersed in water at the bottom of the groove, thereby avoiding damage to the circuit board.

[0022] In one embodiment, a waterproof layer is provided at the position where the heating lamp is connected to the circuit board. The waterproof layer covers the position where the heating lamp is connected to the circuit board. The position where the heating lamp is connected to the circuit board may have gaps or small holes. For example, gaps or small holes are caused by insufficient welding. The gaps or small holes can be covered by providing a waterproof layer, and moisture on the wall can enter the gaps or small holes and cause a short circuit.

[0023] In one embodiment, the circuit board is convexly arranged on the side wall surface of the groove. The circuit board is directly convexly arranged on the side wall surface of the groove, so that the water flow and water vapor directly slide down after passing through the heating mechanism. Compared with opening a groove on the side wall surface to accommodate the circuit board, it avoids moisture accumulation in the groove and reduces the drying effect of the cleaning chamber, and also avoids moisture erosion on the circuit board and the heating lamp, ensuring the reliability of the circuit board and the heating lamp.

[0024] In one of the embodiments, a mounting groove is provided on the side wall of the groove, the circuit board is arranged in the mounting groove, and the heating lamp generates heat toward the roller brush through the notch of the mounting groove. By providing the mounting groove, the circuit board can be firmly installed on the side wall of the groove.

[0027] In one of the embodiments, the connecting pipe has a plurality of air outlet ends, and the plurality of air outlet ends are spaced apart along a direction parallel to the axial direction of the roller brush, so that the plurality of air outlet ends are distributed from one end to the other end of the roller brush, covering a plurality of positions along the length of the roller brush, thereby enabling the roller brush to be heated by a covering jet, thereby greatly improving the drying efficiency of the roller brush.

[0028] In one embodiment, the heating mechanism also includes a diverter, which is connected to the connecting pipe. The diverter divides the connecting pipe into multiple branch pipes to form multiple air outlet ends. Through the setting of the diverter, the connecting pipe can be divided into multiple branches, and then flow into the groove through the multiple branch pipes, each of which has an air outlet end.

[0029] In one embodiment, the heating mechanism also includes a disinfection generator, one end of the disinfection generator is connected to the air supply member through the connecting pipe, and the other end is connected to the heater through the connecting pipe.

[0063] Example 1

[0064] like Figure 1 and Figure 2 As shown, a floor scrubber 10 according to an embodiment includes a main unit 100, a base 200 and a heating mechanism 300. Figure 3 and Figure 4 The host 100 includes a housing 110 and a roller brush 120. The roller brush 120 can rotate around its own axis and is arranged inside the housing 110. The base 200 is provided with a groove 210. The housing 110 and the base 200 are detachably connected. The housing 110 is used to cover the groove 210 to form a cleaning chamber 400. The roller brush 120 is located in the cleaning chamber 400. The heating mechanism 300 is arranged on the base 200. At least part of the heating mechanism 300 is located in the groove 210 and is used to transfer heat to the roller brush 120. In this embodiment, the roller brush 120 is partially arranged inside the housing 110 and partially exposed outside the housing 110. When the housing 110 is connected to the base 200, a part of the roller brush 120 is inside the housing 110 and a part is in the groove 210, that is, the entire roller brush 120 is located in the cleaning chamber 400. In this embodiment, the portion of the heating mechanism 300 located in the groove 210 is used to heat and dry the roller brush 120. In one embodiment, the housing 110 is in contact with the base 200, that is, the housing 110 can be directly placed on the base 200. In one embodiment, the housing 110 is snap-fitted with the base 200, that is, it can be snap-fitted through a bayonet structure and is detachable. In one embodiment, the housing 110 is embedded and connected with the base 200 and is detachable.

[0065] In the above-mentioned floor scrubber 10, the roller brush 120 can be used to clean the floor. After the floor scrubber 10 is used, it is necessary to clean the floor scrubber 10. The cleaned roller brush 120 is wet and contains a large amount of water. By arranging a heating mechanism 300 on the base 200, the part of the heating mechanism 300 located in the groove 210 is used to transfer heat to the roller brush 120 to heat and dry the roller brush 120. A part of the heating mechanism 300 is directly located in the groove 210, which can directly and effectively heat the roller brush 120, and the heating and drying effect is better; and when the roller brush 120 rotates, the roller brush 120 can be heated evenly, not only the air temperature between the heating mechanism 300 and the roller brush 120 is high, but the rotating roller brush 120 can drive the air temperature around the roller brush 120 to increase, so that the temperature in the entire cleaning chamber 400 increases, thereby further improving the drying effect of the roller brush 120; wherein, the roller brush 120 can rotate at a low speed, so that any side of the roller brush 120 can be fully heated when passing through the heating mechanism 300.

[0066] In one of the embodiments, the portion of the heating mechanism 300 located in the groove 210 is arranged on the side wall surface of the groove 210, so as to prevent the portion of the heating mechanism 300 located in the groove 210 from being immersed in the water at the bottom of the groove 210, thereby ensuring that the heating mechanism 300 can stably and reliably heat the drying roller brush 120.

[0067] In order to discharge the hot and humid air in the cleaning chamber 400, in one embodiment, the cleaning chamber 400 has a vent, and the vent is used to connect to the outside world. When the heating mechanism 300 heats and dries the roller brush 120, the roller brush 120 rotates to drive the air flow, and the air temperature around the roller brush 120 increases. The hot and humid air with moisture in the cleaning chamber 400 can be discharged from the vent, and the dry cold air can enter the cleaning chamber 400 from the vent after the hot and humid air is discharged. The dry cold air entering is heated to ensure the balance of air pressure in the cleaning chamber 400. In one embodiment, the number of the vents is multiple, so that the hot and humid air can be discharged through at least one vent, and the dry cold air can flow in through at least one other vent, so that the hot and humid air is discharged while the dry cold air is introduced and heated, ensuring the gas circulation of the cleaning chamber. After a period of circulation, the moisture on the roller brush 120 becomes less and less until it is dry.

[0068] In order to better exhaust the hot and humid air and maintain the temperature in the cleaning chamber 400, in one embodiment, as Figure 1As shown, the two sides of the housing 110 are provided with a mounting shell 111 respectively, one end of the roller brush 120 is connected to one mounting shell 111, and the other end of the roller brush 120 is connected to another mounting shell 111. There is a gap between at least one mounting shell 111 and the base 200, and the gap forms the vent, that is, the gap between at least one mounting shell 111 of the housing 110 and the base 200 forms the vent, and is located at both ends of the roller brush 120, that is, at least one end of the roller brush 120 can form the vent. The humid hot air is discharged through the gap to avoid discharging too much hot air at once; the air that is a little colder tends to sink downward, and the air with moisture tends to sink downward. When the gap is located at the bottom of the cleaning chamber 400, the air with low temperature and moisture that is not good for drying effect will be discharged from the vent formed by the gap, that is, the hot humid air is discharged from the vent, and the humid air and dry air with higher temperature continue to be used to heat and dry the roller brush 120. In this embodiment, the mounting shell includes a main shell and the mounting shell portion 111, the mounting shell portion 111 is connected to both sides of the main shell, for example, is integrally formed, the main shell abuts against the base 200, that is, the other parts of the housing 110 except the mounting shell portion 111 abut against the base 200, and there is a gap between the mounting shell portion 111 and the base 200. In one embodiment, the host 100 is installed in the groove 210, and there is a gap between the mounting shell portion 111 and the bottom surface of the groove 210. In one embodiment, the housing 110 covers a part of the space of the groove 210 to form a cleaning chamber 400, and the other parts of the host 100 are placed in the other parts of the space of the groove 210. In one of the embodiments, there is a gap between the two mounting shells 111 and the base 200, so that a vent can be formed at each end of the roller brush 120, and humid hot air with moisture can be discharged from the vents at both ends of the roller brush 120, or one vent discharges humid hot air and the other vent introduces dry cold air.

[0069] In one embodiment, the shell 110 is a transparent shell, so that the user can observe the drying condition of the roller brush 120 in the cleaning chamber 400 through the shell, and can control the drying operation of the roller brush 120 according to the observed condition.

[0070] In order to better achieve heating and drying, in one embodiment, the heating mechanism 300 includes at least one of a resistive heating element, an infrared heating element and an induction heating element, and the heating mechanism 300 is arranged in the groove 210, that is, the heating mechanism 300 can be a resistive heating element, an infrared heating element, or an induction heating element, or the heating mechanism 300 is composed of two or three of the resistive heating element, the infrared heating element and the induction heating element.
