Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a sewage tank and cleaning equipment. Background Art

[0002] During use, the cleaning equipment can suck up garbage and wastewater on the ground through the vacuum motor and finally collect them into the sewage tank. After cleaning, the user needs to dump the sewage in the sewage tank and clean the sewage tank.

[0003] To clean stubborn dirt from sewage tanks, some cleaning equipment is equipped with an ultrasonic generator. This generates vibrations that dislodge dirt adhering to the tank's inner walls. However, this ultrasonic generator generates significant heat during use, raising the temperature inside the cleaning equipment and even accelerating the aging of its electronic components. Utility Model Content

[0004] In view of this, the present invention provides a cleaning device to solve the problem in the related art that the ultrasonic generator of the cleaning device easily causes the internal temperature of the cleaning device to rise and even accelerates the aging of electronic components inside the cleaning device.

[0005] The utility model provides a cleaning device, comprising:

[0006] a main body, on which an air inlet, an air outlet channel and an exhaust port are formed;

[0007] A sewage tank, wherein the inlet of the sewage tank is connected to the air inlet;

[0008] a vacuum device, the air inlet side of which is connected to the outlet of the sewage tank, the outlet of the sewage tank is connected to the first end of the air outlet channel, and the second end of the air outlet channel is connected to the exhaust port;

[0009] The ultrasonic generator is arranged on the sewage tank, and the air outlet channel is at least partially located on one side of the ultrasonic generator.

[0010] Beneficial Effects: During use, the ultrasonic generator of the cleaning device according to the present invention generates vibrations that shake away dirt adhering to the inner wall of the sewage tank. The vacuum device drives airflow through the main body's air inlet, the sewage tank, the exhaust passage, and the main body's exhaust port, thereby drawing wastewater and pollutants from the outside into the sewage tank, thereby achieving a cleaning effect.

[0011] When the sewage tank needs to be cleaned, the energy generated by the vibration of the ultrasonic generator can use the water in the sewage tank as a medium to shake off the dirt on the inner wall of the sewage tank. The user can then dump the dirt and sewage in the sewage tank. When the cleaning equipment is equipped with a cleaning base station, the sewage in the sewage tank can also be discharged through the accompanying cleaning base station, thereby achieving thorough cleaning of stubborn stains on the inner wall of the sewage tank.

[0012] Since the air outlet channel is located on one side of the ultrasonic generator, when the vacuum device drives the air flow to be discharged through the air outlet channel, the air flow can flow through one side of the ultrasonic generator and carry the heat generated by the ultrasonic generator during the vibration process to the outside, thereby cooling the ultrasonic generator to avoid the temperature inside the cleaning equipment from rising, which will accelerate the aging of the electronic components inside the cleaning equipment.

[0013] On this basis, since the cleaning device of the embodiment of the utility model can cool the ultrasonic generator with the help of the airflow generated by the vacuum device, the power of the ultrasonic generator is allowed to be set higher, thereby improving the cleaning effect of the ultrasonic generator on the sewage tank.

[0014] Therefore, the cleaning device of the embodiment of the present invention can cool the ultrasonic generator to avoid the temperature inside the cleaning equipment from rising, which may accelerate the aging of electronic components inside the cleaning equipment, and help improve the cleaning effect of the ultrasonic generator on the sewage tank.

[0016] Beneficial effect: Through such an arrangement, the side walls of the sewage tank and the groove walls of the mounting groove can be used to enclose an air outlet channel, thereby forming an air outlet channel in the main body without adding a channel structure, which can make the structure of the cleaning device more compact and help promote the airflow in the air outlet channel to cool the ultrasonic generator.

[0017] In an optional embodiment, the sewage tank includes:

[0018] The box body is provided with a heat-resistant sheet, the melting point of the heat-resistant sheet is higher than the melting point of the box body, and the ultrasonic generator is connected to the heat-resistant sheet.

[0022] In an optional embodiment, the ultrasonic generator is disposed in the middle of the first wall.

[0023] Beneficial effect: Through such an arrangement, the vibration of the ultrasonic generator can be transmitted more evenly, thereby improving the cleaning effect of the ultrasonic generator on the sewage tank and making the cleaning more efficient.

Through such an arrangement, when the sewage tank is arranged in the installation groove, the third conductive part can be connected to the first conductive part, and the fourth conductive part can be connected to the second conductive part, thereby realizing the power-on of the ultrasonic generator.

[0028] When the sewage tank is removed from the installation slot, the third conductive part can be separated from the first conductive part, and the fourth conductive part can be separated from the second conductive part, thereby achieving power failure of the ultrasonic generator when the sewage tank is removed from the installation slot.

[0054] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0055] The sewage tank 2 of the cleaning equipment is used to temporarily store dirt during the cleaning process of the cleaning equipment. The stored dirt adheres to the inner wall of the sewage tank 2, which is prone to breed bacteria and stink.

[0056] In the related art, after the floor scrubber finishes cleaning the floor, the user needs to dump the dirt in the sewage tank 2 and clean the sewage tank 2. During the cleaning process, the user has to face the dirt and clean the sewage tank 2 manually. If the user does not clean it thoroughly, the sewage tank 2 will breed bacteria and become smelly over time.

[0057] The following combination Figures 1 to 10 , describing the embodiments of the present utility model.

[0058] According to an embodiment of the present invention, a cleaning device is provided, comprising a main body 1, a sewage tank 2, a vacuum device 3, and an ultrasonic generator 4. The main body 1 is formed with an air inlet, an air outlet channel 101, and an exhaust port. The inlet of the sewage tank 2 is connected to the air inlet. The air inlet side of the vacuum device 3 is connected to the outlet of the sewage tank 2, the air outlet side of the vacuum device 3 is connected to the first end of the air outlet channel 101, and the second end of the air outlet channel 101 is connected to the exhaust port. The ultrasonic generator 4 is disposed on the sewage tank 2, with the air outlet channel 101 at least partially located on one side of the ultrasonic generator 4.

[0059] During use, the cleaning device of this embodiment of the utility model generates vibrations that shake off dirt adhering to the inner wall of the sewage tank 2. The vacuum device 3 drives air to flow sequentially through the air inlet of the main body 1, the sewage tank 2, the exhaust passage, and the exhaust port of the main body 1, thereby drawing wastewater and pollutants from the outside into the sewage tank 2, thereby achieving a cleaning effect.

[0060] When the sewage tank 2 needs to be cleaned, the energy generated by the vibration of the ultrasonic generator 4 can use the water in the sewage tank 2 as a medium to shake off the dirt on the inner wall of the sewage tank 2. The user then dumps out the dirt and sewage in the sewage tank 2. When the cleaning device is equipped with a cleaning base station, the sewage in the sewage tank 2 can also be discharged through the accompanying cleaning base station, thereby achieving thorough cleaning of stubborn stains on the inner wall of the sewage tank 2.

[0061] Since the air outlet channel 101 is located on one side of the ultrasonic generator 4, when the vacuum device 3 drives the airflow to be discharged through the air outlet channel 101, the airflow can flow through one side of the ultrasonic generator 4 and carry the heat generated by the ultrasonic generator 4 during the vibration process to the outside, thereby cooling the ultrasonic generator 4 to avoid the temperature inside the cleaning equipment from rising, which will accelerate the aging of the electronic components inside the cleaning equipment.

[0062] On this basis, since the cleaning device of the embodiment of the utility model can cool the ultrasonic generator 4 with the help of the airflow generated by the vacuum device 3, the power of the ultrasonic generator 4 is allowed to be set higher, thereby improving the cleaning effect of the ultrasonic generator 4 on the sewage tank 2.

[0063] Therefore, the cleaning device of the embodiment of the present invention can cool the ultrasonic generator 4 to avoid the temperature inside the cleaning equipment from rising, which may accelerate the aging of electronic components inside the cleaning equipment, and help improve the cleaning effect of the ultrasonic generator 4 on the sewage tank 2.

[0067] In an optional embodiment, the air outlet channel 101 may be located at one side of the sewage tank 2 .

[0071] The heat-resistant sheet 202 can replace the box body 201 to be connected to the ultrasonic generator 4, thereby avoiding the heat generated by the vibration of the ultrasonic generator 4 causing the box body 201 to melt, and allowing the power of the ultrasonic generator 4 to be set higher to improve the cleaning effect of the ultrasonic generator 4 on the sewage tank 2.

[0072] The heat-resistant sheet 202 is preferably, but not limited to, made of heat-resistant metal, ceramic or polymer heat-resistant material.

[0073] The heat-resistant metal is preferably, but not limited to, stainless steel or nickel-based alloy.

[0075] In an optional embodiment, if Figure 5 As shown, the heat-resistant sheet 202 is a metal sheet, and a mounting opening 203 is formed on the first wall of the box body 201. The heat-resistant sheet 202 is arranged in the box body 201 and covered at the mounting opening 203. The ultrasonic generator 4 is arranged in the mounting opening 203 and connected to the heat-resistant sheet 202.

[0076] Through such a configuration, the metal sheet can be connected to the box body 201, and the ultrasonic generator 4 can also be connected to the metal sheet by bonding, clamping or threaded connection, which can make the assembly process of the sewage tank 2 simple and convenient, and the ultrasonic generator 4 can be accommodated in the installation opening 203 without protruding from the surface of the box body 201, thereby reducing the risk of interference between the ultrasonic generator 4 and the main body 1 during use.

[0077] The metal sheet may be optionally connected to the box body 201 by inlay injection molding, thereby ensuring a reliable connection between the technical sheet and the box body 201 while improving the reliability of the connection between the metal sheet and the box body 201 .

[0078] As a convertible embodiment, the metal sheet can also be connected to the box body 201 by bonding, snapping or threading.

[0079] As an alternative embodiment, the metal sheet may also be configured to be connected to the box body 201 on the outside of the box body 201 .

[0080] In an optional embodiment, the ultrasonic generator 4 is disposed in the middle of the first wall.

[0081] By such an arrangement, the vibration of the ultrasonic generator 4 can be transmitted more evenly, thereby improving the cleaning effect of the ultrasonic generator 4 on the sewage tank 2 and making the cleaning more efficient.

[0082] As an alternative embodiment, the ultrasonic generator 4 can also be arranged at the end of the sewage tank 2 .

[0083] In an optional embodiment, if Figure 5 and Figure 6 As shown, the sewage tank 2 is detachably connected to the mounting slot 102 , and a first conductive portion 204 and a second conductive portion 205 are further provided on the sewage tank 2 , and the ultrasonic generator 4 is connected in series between the first conductive portion 204 and the second conductive portion 205 ;

[0084] like Figure 8 As shown, a third conductive portion 103 and a fourth conductive portion 104 are provided at the bottom of the installation groove 102 . When the sewage tank 2 is arranged in the installation groove 102 , the third conductive portion 103 can be connected to the first conductive portion 204 , and the fourth conductive portion 104 can be connected to the second conductive portion 205 .

[0085] The power board of the cleaning equipment can be optionally connected in series between the third conductive part 103 and the fourth conductive part 104. By such an arrangement, when the sewage tank 2 is arranged in the mounting groove 102, the third conductive part 103 can be connected to the first conductive part 204, and the fourth conductive part 104 can be connected to the second conductive part 205, thereby realizing the power-on of the ultrasonic generator 4.

[0086] When the sewage tank 2 is removed from the mounting groove 102 , the third conductive portion 103 can be separated from the first conductive portion 204 , and the fourth conductive portion 104 can be separated from the second conductive portion 205 , thereby achieving power failure of the ultrasonic generator 4 when the sewage tank 2 is removed from the mounting groove 102 .

[0087] In an optional embodiment, if Figure 9 As shown, the first conductive portion 204 includes a first conductive sheet 2041 and a first protrusion 2042 provided on the first conductive sheet 2041, the second conductive portion 205 includes a second conductive sheet 2051 and a second protrusion 2052 provided on the second conductive sheet 2051, and the sewage tank 2 further includes:

[0088] The insulating cover 206 is detachably connected to the box body 201. Figure 10 As shown, a first avoidance opening 2061 and a second avoidance opening 2062 are formed on the insulating cover 206 . The first protrusion 2042 can pass through the first avoidance opening 2061 to connect to the third conductive part 103 , and the second protrusion 2052 can pass through the second avoidance opening 2062 to connect to the fourth conductive part 104 .

[0089] By such a configuration, the insulating cover 206 can be covered on the first conductive sheet 2041 and the second conductive sheet 2051, thereby limiting the first conductive sheet 2041 and the second conductive sheet 2051 and improving the insulation of the first conductive sheet 2041 and the second conductive sheet 2051. At the same time, the first avoidance opening 2061 and the second avoidance opening 2062 can allow the first protrusion 2042 and the second protrusion 2052 to pass through and respectively connect the third conductive part 103 and the fourth conductive part 104.

[0090] In addition, the first conductive part and the third conductive part, as well as the second conductive part and the fourth conductive part of the ultrasonic generator 4 in the embodiment of the present application are energized by contact, which makes it less likely for poor contact to be caused by loose conductive sheets.

[0091] In one embodiment, the third conductive portion 103 and the fourth conductive portion 104 are conductive pillars, which can extend into the first avoidance opening 2061 and the second avoidance opening 2062 respectively, and contact the first protrusion 2042 and the second protrusion 2052 respectively.

[0092] As an alternative embodiment, the third conductive portion 103 and the fourth conductive portion 104 may also be configured to include a conductive sheet and a conductive protrusion, respectively.

[0093] In one embodiment, a first connection hole 2063 and a second connection hole 2011 are formed on the insulating cover plate 206 and the box body 201 , respectively. The first connection hole 2063 is used for a fastener to pass through and connect to the second connection hole 2011 .

[0094] With such a configuration, the fasteners can pass through the insulating cover 206 and connect to the box body 201 , thereby fixing the insulating cover 206 on the box body 201 .

[0095] In a preferred embodiment, a threaded column is formed on the box body 201, and the second connecting hole 2011 is a threaded hole formed in the threaded column.

[0096] By such arrangement, the insulating cover 206 can be reliably connected to the box body 201 without opening the box body 201 , thereby avoiding the risk of water leakage in the sewage tank 2 caused by opening a hole in the box body 201 .

[0097] As a convertible embodiment, the insulating cover 206 may also be connected to the box body 201 by means of snap connection, riveting or bonding.

[0098] In one embodiment, a receiving groove 207 is formed on the sewage tank 2 , and the insulating cover 206 is disposed in the receiving groove 207 .

[0099] By such a configuration, the accommodating groove 207 can limit the insulating cover plate 206 in an accommodating manner, thereby improving the reliability of the connection between the insulating cover plate 206 and the accommodating groove 207 and preventing the insulating cover plate 206 from shifting during use.

[0100] In a preferred embodiment, the insulating cover 206 is configured to be flush with the outer wall of the box body 201 when connected to the box body 201, thereby improving the aesthetics of the sewage tank 2 and reducing the risk of interference between the insulating cover 206 and the main body 1 when the sewage tank 2 is assembled on the main body 1.

[0101] In a preferred embodiment, a limiting plate is formed on one side edge of the insulating cover 206, and a limiting groove is correspondingly formed on the groove wall of the accommodating groove 207. When the operator installs the insulating cover 206 on the box body 201, he can first insert the limiting plate into the limiting groove, and then rotate the insulating cover 206 with the connection between the limiting groove and the limiting plate as the axis, so as to accurately place the insulating cover 206 into the limiting groove.

[0102] In one embodiment, the cleaning device may be a floor scrubber. As a convertible embodiment, the cleaning device may also be a sweeping robot or a fabric cleaner.

[0103] Next, the installation process of the cleaning device according to the embodiment of the present invention is described:

[0104] First, the metal sheet is integrally connected to the tank body 201 through an insert injection molding process. Next, the ultrasonic generator 4 is glued to the metal sheet. A wire is connected in series between the first conductive portion 204 and the second conductive portion 205. Finally, the insulating cover 206 is screwed to the tank body 201. Finally, the assembled sewage tank 2 is installed on the cleaning device's main body 1. At this point, the first conductive portion 204 is connected to the third conductive portion 103, and the second conductive portion 205 is connected to the fourth conductive portion 104, forming a complete circuit capable of powering the ultrasonic generator 4.

[0105] Next, the cleaning process of the cleaning device according to the embodiment of the present invention is described:

[0106] After the roller brush of the cleaning equipment has been self-cleaned, the floor brush continues to supply water to the sewage tank 2 until the water level in the sewage tank 2 reaches the designed maximum water level.

[0107] When the sewage tank 2 is filled to the designed maximum water level, the ultrasonic generator 4 vibrates, and the metal sheet connected to it can transmit the vibration. Using the water in the sewage tank 2 as a medium, the energy generated by the ultrasonic generator 4 shakes off the dirt on the inner wall of the sewage tank 2. The user then dumps the dirt and sewage in the sewage tank 2. When the cleaning device is equipped with a cleaning base station, the sewage in the sewage tank 2 can also be discharged through the attached cleaning base station, thereby achieving thorough cleaning of stubborn stains on the inner wall of the sewage tank 2.
