Description

Technical Field

[0001] The invention relates to the technical field of dust collection equipment, and in particular to a dust collection device. Background Art

[0002] Most vacuum cleaners in the related art use a motor to drive a fan to rotate, and use the fan to achieve a vacuuming effect, which has a single function. When encountering smooth surfaces such as tiles and surfaces stained with difficult-to-clean substances, vacuum cleaners in the related art cannot achieve a good cleaning effect, and often need to use a mop to clean the surface after vacuuming, which is time-consuming and laborious.

[0003] That is to say, the vacuum cleaners in the related art have single functions and limited cleaning capabilities and cannot meet the requirements of multi-function and multi-purpose. Summary of the invention

[0004] In view of the above problems in the prior art, the present application proposes a dust collection device, which solves the problem that the vacuum cleaner has a single function, limited cleaning ability, and cannot meet the multi-function and multi-purpose requirements.

[0006] In one embodiment, the cleaning component includes: a steam generator for generating cleaning steam; a pumping member for pumping in cleaning liquid; a waterway for conveying cleaning liquid or cleaning steam; a nozzle connected to the waterway for spraying cleaning liquid or cleaning steam onto the wet mopping component; and a switching structure for connecting the waterway to the steam generator or the pumping member. In this embodiment, the waterway can be switched to be connected to the steam generator or the pumping member by operating the switching structure, thereby realizing the high-temperature steam wetting function or the clean water wetting function of the dust collecting device, thereby meeting different wetting requirements of the wet mopping component.

Through this embodiment, the steam generator ensures that the water circuit is connected to the steam generator before heating to generate high-temperature steam, which saves the cost of generating high-temperature steam and thus reduces the cost of using the dust collector.

[0008] In one embodiment, the switching structure includes a rotary switching knob and a switching knob plugging end connected to the rotary switching knob. By rotating the rotary switching knob, the switching knob plugging end is driven to rotate a certain angle to selectively conduct the delivery pipeline of the cleaning liquid or cleaning steam. Through this embodiment, the switching structure realizes the selective conduction of the water path with the pumping part and the steam generator by rotating. This kind of twisting switching method is cleverly designed and convenient for manual operation, thereby improving the convenience of using the dust collector.

[0009] In one embodiment, the rotation angle range of the blocking end of the switching knob is set to 20° to 150°.

[0011] In one embodiment, it also includes a duct lower shell and an duct upper shell arranged on the duct lower shell, the dust suction duct is located between the duct upper shell and the duct lower shell, the duct inlet is arranged on the duct lower shell, and the duct outlet is arranged on the duct upper shell.

[0012] In one embodiment, it also includes an upper shell assembly, which is arranged on the upper shell of the air duct, and the cleaning assembly is arranged in an installation cavity formed between the upper shell assembly and the upper shell of the air duct.

[0013] In one embodiment, the wet mopping assembly includes a rag and a rag holder, one end of the rag holder is connected to the rag, and the other end is inserted into the lower shell of the air duct of the dust collecting device.

[0014] In one embodiment, a roller brush is further included, which is rotatably disposed at the bottom of the lower shell of the air duct and is disposed corresponding to the rag of the wet mopping assembly and the air duct inlet.

[0015] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the purpose of the present invention can be achieved.

[0016] Compared with the prior art, the dust collecting device provided by the present invention has at least the following beneficial effects:

[0017] The dust suction device has dust suction and wet mopping functions, that is, the dust suction device can complete the dust suction and wet mopping functions of the area to be cleaned, thereby enhancing its cleaning ability. Moreover, the cleaning component can spray cleaning steam to the wet mopping component, so that while wetting the wet mopping component, the cleaning steam can disinfect and sterilize the area to be cleaned on the ground, so that the dust suction device has a sterilization function, and the cleaning steam can also make the area to be cleaned easy to dry. Since the dust suction device in the present application has three functions of dust suction, wet mopping and sterilization, the function of the dust suction device is enhanced, its use is expanded, and the multi-functional and multi-purpose requirements of the dust suction device are met.

After the duct adapter assembly 30 has sucked the garbage in the area to be cleaned, the cleaning assembly 40 can wet mop the area to be cleaned.

[0032] In the above arrangement, since the dust suction device is integrated with the wet mopping component 20 and the air duct adapter component 30, after the air duct adapter component 30 has sucked the garbage in the area to be cleaned, the cleaning component 40 can wet mop the area to be cleaned. In this way, the dust suction device has dust suction and wet mopping functions, that is, the dust suction device can complete the dust suction and wet mopping functions of the area to be cleaned, thereby enhancing its cleaning ability. Moreover, the cleaning component 40 can spray cleaning steam to the wet mopping component 20, so that while wetting the wet mopping component 20, the cleaning steam can disinfect and sterilize the area to be cleaned on the ground, thereby making the dust suction device have a sterilization function, and the cleaning steam can also make the area to be cleaned easy to dry. Since the dust suction device in the present application has the three functions of dust suction, wet mopping and sterilization, the function of the dust suction device is enhanced, and its use is expanded, thereby meeting the multi-functional and multi-purpose requirements of the dust suction device.

[0033] Specifically, Figures 1 to 4 As shown, in the embodiment of the present invention, a detachable air duct adapter assembly 30 is inserted on the air duct upper shell 51, and the air duct adapter assembly 30 is connected to the dry suction air duct outlet 133, which is used to suck the garbage in the dust removal area. A dust cup is provided in the air duct adapter assembly 30 for collecting garbage. Of course, according to the actual cleaning conditions, other accessories with different functions can also be inserted into the air duct upper shell 51 to achieve whole-house cleaning.

[0034] Specifically, Figures 1 to 4 As shown, in an embodiment of the present invention, the cleaning assembly 40 includes a steam generator 41, a pumping member 42, a nozzle 43 and a switching structure 44.

[0035] In the above arrangement, the water path can be switched to communicate with the steam generator 41 or the pumping member 42 by operating the switching structure 44 , thereby realizing the high-temperature steam wetting function or the clean water wetting function of the dust collecting device, thereby meeting different wetting requirements of the wet mopping assembly 20 .

[0036] Specifically, in the embodiment of the present invention, when the area to be cleaned needs to be sterilized at high temperature, the switch structure 44 can be operated to connect the water circuit with the steam generator 41, and then the high-temperature steam is delivered to the cleaning component 40 for moistening and sterilizing. Normally, the switch structure 44 can be operated to connect the water circuit with the pumping member 42, and then the clean water is delivered to the wet mopping component 20 for moistening.

[0037] Specifically, the pumping member 42 is a water pump, and the water pump is used to pump clean water.

[0038] Specifically, Figures 1 to 4 As shown, in the embodiment of the present invention, the steam generator 41 includes a body, a heater, a control circuit board 411 and a sensor. The heater is arranged on the body; the control circuit board 411 is electrically connected to the heater; the sensor is electrically connected to the control circuit board 411; when the water path is connected to the steam generator 41, the control circuit board 411 can receive the signal sent by the sensor and control the heater to heat the liquid in the body to generate cleaning steam.

[0039] In the above arrangement, the steam generator 41 ensures that the water path is connected to the steam generator 41 before heating and generating high-temperature steam, which saves the cost of generating high-temperature steam and thus reduces the use cost of the dust collection device.

By rotating the rotating switching knob 441, the switching knob blocking hole end 442 is driven to rotate a certain angle to complete the switching function of the switching structure 44.

[0042] In the above arrangement, the switching structure 44 realizes the selective conduction between the water path and the pumping member 42 and the steam generator 41 by means of rotation. The rotating switching method is cleverly designed and convenient for manual operation, thereby improving the convenience of using the dust collecting device.

[0043] Specifically, in an embodiment of the present invention, the rotation angle range of the switching knob blocking end 442 is set to 20° to 150°, inclusive.

[0044] Specifically, Figure 1 As shown, in the embodiment of the present invention, the wet mopping assembly 20 includes two rags 21 .

[0045] Combine the following Figures 1 to 4 , describing a complete embodiment of the present application:

[0046] The present application provides a dust collecting device, comprising a duct lower shell 52 and a duct upper shell 51 disposed on the duct lower shell 52, the dust collecting duct 10 is located between the duct upper shell 51 and the duct lower shell 52, the duct inlet is disposed on the duct lower shell 52, and the duct outlet is disposed on the duct upper shell 51. The dust collecting device further comprises an upper shell assembly 60, the upper shell assembly 60 is disposed on the duct upper shell 51, and the cleaning assembly 40 is disposed in an installation cavity formed between the upper shell assembly 60 and the duct upper shell 51. The upper shell assembly 60 is provided with an upper shell water inlet 61 for water inlet.

[0047] The vacuum cleaner also includes a wet mop assembly 20, which is arranged at the bottom of the air duct lower shell 52 and near the air duct inlet. The wet mop assembly 20 includes two symmetrically arranged rags 21 and two rag holders 22 arranged one by one. One end of the rag holder 22 is connected to the rag 21, and the other end is inserted into the air duct lower shell 52 of the vacuum cleaner. The rag 21 is a triangular rag, and the material can be a water-absorbing material, such as foam.

[0048] The cleaning component 40 also includes a steam generator 41, a pumping member 42, a nozzle 43 and a switching structure 44. The steam generator 41 is used to generate cleaning steam. The pumping member 42 is used to pump in cleaning liquid. The waterway is used to transport cleaning liquid or cleaning steam. The nozzle 43 is connected to the waterway and is used to spray the cleaning liquid or cleaning steam onto the wet mopping component 20. The switching structure 44 is used to connect the waterway with the steam generator 41 or the pumping member 42. There are two nozzles 43, which are respectively inserted into the jacks of the two rag brackets 22 through the lower shell 52 of the air duct, and the spraying end thereof is located above the rag 21. The dust collecting device also includes an upper shell assembly 60, which is arranged on the upper shell 51 of the air duct, and the cleaning component 40 is arranged in the installation cavity formed between the upper shell assembly 60 and the upper shell 51 of the air duct. The cleaning component 40 also includes a three-way joint 45, which is connected to the waterway, and the cleaning steam is transmitted to the nozzle 43 through the three-way joint 45.

[0049] The dust collecting device also includes a roller brush 71, which is rotatably arranged at the bottom of the air duct lower shell 52 and is arranged corresponding to the rag 21 of the wet mopping assembly 20 and the air duct inlet. The dust collecting device also includes a roller brush driving device 80, which includes a double-headed screw motor 81 and a gearbox gear 82 connected to the double-headed screw motor 81, and the gearbox gear 82 is installed in the installation cavity defined by the gearbox upper shell 83 and the gearbox lower shell 84. The roller brush 71 is connected to the output end of the gearbox through a belt to realize driving.

[0050] The steam / water switching function in this application is mainly achieved by rotating the rotary switch knob 441 on the upper end of the upper shell assembly 60 to drive the switch knob plugging end 442 to rotate 90 degrees, so that the water circuit is connected to the steam generator 41. At the same time, the sensor on the steam generator 41 generates a signal to feed back to the PCB board to connect the circuit, and the steam generated by heating is transmitted to the nozzle 43 through the three-way joint 45, and sprayed onto the triangular rag for sterilization and disinfection, and to accelerate the drying of the ground. If the cleaning steam is not needed, just rotate the rotary switch knob 441 back to cut off the connection channel between the water circuit and the steam generator 41, connect the water circuit and the three-way joint 45 channel, and spray uniform water droplets through the nozzle 43 to accelerate the wetting of the triangular rag and increase the water content, so as to achieve the purpose of wet mopping;

[0051] The structure of the present invention is to integrate a steam generator 41 and use the same direction and coaxial rag to spray steam uniformly, so as to achieve uniform wetting of the rag 21, easy drying, and disinfection and sterilization of the floor. And through the control of the switch mechanism, the pipeline between the water pump and the steam generator 41 is physically switched, and water in different states is sprayed through the nozzle 43 to meet the different mopping needs of users.

[0052] Specifically, Figures 1 to 4 As shown, the dust collection device includes a dry suction duct 13, a wet suction duct 14 and an air duct switching assembly 90. Among them, the dry suction duct 13 has a first dry suction duct inlet 131, a second dry suction duct inlet 132 and a dry suction duct outlet 133. The wet suction duct 14 has a wet suction duct inlet 141 and a wet suction duct outlet 142, and the wet suction duct outlet 142 is connected to the second dry suction duct inlet 132. Under the action of external suction force, the air duct switching assembly 90 can selectively suck the garbage in the area to be dusted from the first dry suction duct inlet 131 into the dry suction duct 13, or suck the garbage in the area to be dusted from the wet suction duct inlet 141 into the wet suction duct 14. The wet suction duct 14 can separate the garbage therein from dry and wet, and the separated dry garbage enters the dry suction duct 13 through the wet suction duct outlet 142 and the second dry suction duct inlet 132 in turn under the action of external suction force, and is discharged from the dry suction duct outlet 133.

[0053] In the above arrangement, since the wet suction duct 14 can separate the wet and dry garbage, the wet garbage remains in the wet suction duct 14, and the dry garbage enters the dry suction duct 13 and then enters the dust cup in the duct adapter assembly 30. In this way, the function of separating the wet and dry garbage in the dust removal area is realized, thereby avoiding the problem that the dust suction device in the related art is difficult to clean the mixed wet and dry garbage, thereby enhancing the dust removal ability of the dust suction device and expanding its scope of use.

[0054] Specifically, Figures 1 to 4 As shown, in an embodiment of the present invention, the dust collection device also includes a duct lower shell 52 and an duct upper shell 51 arranged on the duct lower shell 52, the dry suction duct 13 is formed between the duct upper shell 51 and the duct lower shell 52, the first dry suction duct inlet 131 and the wet suction duct inlet 141 are arranged in the duct lower shell 52, and the second dry suction duct inlet 132 and the dry suction duct outlet 133 are arranged in the duct upper shell 51.

[0055] In the above arrangement, the positions of the inlet and outlet of each air duct are arranged to ensure that the garbage in the dust removal area can first enter the wet suction duct 14 for dry-wet separation, leaving the wet garbage in the wet suction duct 14 for subsequent cleaning, and the dry garbage can enter the dry suction duct 13 and be sucked into the dust collection cup. This ensures that the dry-wet separation function of the dust collection device is realized, and further ensures that the dust collection device can clean the dry and wet mixed garbage.

[0056] Specifically, Figure 3 , Figure 5 and Figure 6 As shown, in an embodiment of the present invention, the air duct switching assembly 90 includes a driving part 91 and a shielding part 92 connected to the driving part 91, and the driving part 91 can drive the shielding part 92 to operate so as to selectively shield the first dry suction duct inlet 131 or the wet suction duct inlet 141.

[0057] In the above configuration, the air duct switching component 90 can selectively block the first dry suction duct inlet 131 or the wet suction duct inlet 141. That is, when the air duct switching component 90 blocks the first dry suction duct inlet 131, the first dry suction duct inlet 131 is blocked by the blocking portion 92, and garbage can only be sucked in from the wet suction duct inlet 141. When the air duct switching component 90 blocks the wet suction duct inlet 141, the wet suction duct inlet 141 is blocked by the blocking portion 92, and garbage can only be sucked in from the first dry suction duct inlet 131. This ensures that the user can choose whether to enable the dry and wet separation function of the dust collection device according to the dryness and wetness of the garbage, so as to better clean the garbage in the area to be dusted.

[0058] Specifically, Figure 5 and Figure 6 As shown, in an embodiment of the present invention, the driving part 91 includes a non-coaxial driving motor 911 and a hook 912 connected to the output end of the non-coaxial driving motor 911 , and a first sliding groove 9121 is provided on the hook 912 .

[0059] In the above setting, the groove wall of the first slide groove 9121 can act as a driving end to drive the shielding part 92 to move, so that the shielding part 92 can selectively block the first dry suction duct inlet 131 and the wet suction duct inlet 141, thereby ensuring that the dry and wet separation function of the dust collection device is realized.

[0060] Specifically, Figure 5 and Figure 6 As shown, in an embodiment of the present invention, a second slide groove 5111 is provided at the side end 511 of the air duct upper shell 51, and the shielding portion 92 includes an air duct switching plate 921 and a sliding shaft 922 arranged on one side of the air duct switching plate 921, and the sliding shaft 922 is inserted into the first slide groove 9121 and the second slide groove 5111 at the same time. When the non-coaxial drive motor 911 rotates, the hook 912 can drive the sliding shaft 922 to slide in the second slide groove 5111 to the first position where the air duct switching plate 921 blocks the first dry suction duct inlet 131 or the second position where the air duct switching plate 921 blocks the wet suction duct inlet 141.

[0061] In the above-mentioned setting, the groove wall of the first slide groove 9121 abuts against the sliding shaft 922 to drive the sliding shaft 922 to slide simultaneously in the first slide groove 9121 and the second slide groove 5111, so that the air duct switching plate 921 swings along the sliding trajectory of the sliding shaft 922 in the second slide groove 5111, thereby realizing the selective shielding of the first dry suction duct inlet 131 and the wet suction duct inlet 141 by the air duct switching plate 921, so as to ensure that the dry-wet separation function of the dust collection device can be realized.

[0062] Specifically, Figures 1 to 4 As shown, in an embodiment of the present invention, the dust collection device further includes a sewage tank assembly 100, the sewage tank assembly includes a sewage tank body 101, the sewage tank body 101 is arranged on the air duct upper shell 51, the sewage tank body 101 is provided with an inlet 1011 and a wet suction air duct outlet 142, and the inlet 1011 is connected to the wet suction air duct inlet 141.

[0063] Specifically, Figures 1 to 4 As shown, in the embodiment of the present invention, a plug-in structure is provided between the sewage tank body 101 and the air duct upper shell 51 for connecting the sewage tank body 101 and the air duct upper shell 51 .

[0064] In the above arrangement, the plug-in structure can ensure that the sewage tank body 101 is fixedly connected to the air duct upper shell 51, thereby ensuring that the wet suction duct inlet 141 is connected to the sewage tank body 101, and further ensuring that the garbage can be separated into dry and wet in the sewage tank body 101, so as to realize the dry and wet separation function of the dust collection device.

[0065] Specifically, Figures 1 to 4 As shown, in an embodiment of the present invention, the plug-in structure includes a plug-in block 201 arranged on the air duct upper shell 51 and an inlet 1011 plugged with the plug-in block 201. The plug-in block 201 is a hollow structure, and the hollow part and the inner cavity of the sewage tank body 101 form a wet suction air duct 14.

[0066] Specifically, Figures 1 to 4 As shown, in the embodiment of the present invention, a mounting groove 2011 is provided on the outer periphery of the plug-in block 201 , and a sealing ring is provided in the mounting groove 2011 .

[0067] In the above arrangement, the sealing ring is used to seal the annular gap between the plug-in block 201 and the inlet 1011, thereby ensuring that garbage cannot leak from the annular gap, thereby improving the dust removal ability of the dust collection device.

[0068] Specifically, Figures 1 to 4 As shown, in the embodiment of the present invention, the plug-in block 201 is a hollow rectangular parallelepiped structure.

[0070] In the above arrangement, the sewage tank body 101 can be snap-connected to the upper shell assembly 60 by pressing the fixing button 102. This facilitates the disassembly and assembly of the dust collecting device, thereby improving its convenience of use.

[0071] It should be noted that the fixing button 102 is inserted into the upper shell reserved groove 62 of the upper shell assembly 60 and snapped into the upper shell buckle 63 of the upper shell assembly 60, so that the wet suction duct outlet 142 is aligned and tightly sealed with the second dry suction duct inlet 132. At the same time, the sewage and air are separated by the filtering structure arranged in the sewage tank body 101.

[0072] Specifically, Figures 1 to 4 As shown, in an embodiment of the present invention, the dust collection device further includes a humidity monitoring device 300 , which is disposed at the bottom of the air duct lower shell 52 and corresponds to the wet suction air duct inlet 141 .

[0073] In the above settings, the user can judge the dryness and wetness of the garbage in the dust removal area according to the monitored humidity of the humidity monitoring device 300, so as to facilitate the user to determine whether to use the dry-wet separation function of the dust collection device, that is, when the humidity of the garbage in the dust removal area is too high, the dry-wet separation function is turned on, and when the humidity of the garbage in the dust removal area is not high, the dry-wet separation function is not turned on. This improves the dust collection efficiency of the dust collection device.

[0074] Specifically, Figures 1 to 4 As shown, in the embodiment of the present invention, the humidity monitoring device 300 is a humidity sensor installed at the front end of the bottom of the lower shell 52 of the air duct.

[0075] Specifically, in an embodiment of the present invention, a switching value is set for the humidity sensor, and switching between different suction ports is performed according to the switching value set by the humidity sensor.

[0076] The non-coaxial drive motor 911 is electrically connected to the PCB circuit board, and a chip is provided on the PCB circuit board. By setting the chip, the rotation angle of the non-coaxial drive motor 911 can be controlled, thereby controlling the swing of the air duct switching plate 921. When the non-coaxial drive motor 911 rotates, the hook 912 can drive the sliding shaft 922 to slide in the second slide groove 5111 to the first position where the air duct switching plate 921 blocks the first dry suction air duct inlet 131, and the wet suction air duct inlet 141 is in an open state. When the non-coaxial drive motor 911 rotates, the hook 912 can drive the sliding shaft 922 to slide in the second slide groove 5111 to the second position where the air duct switching plate 921 blocks the wet suction air duct inlet 141, and the first dry suction air duct inlet 131 is in an open state.
