[0036] The utility model provides a kind of cleaning equipment 100, the cleaning equipment 100 can be set as dust collector, floor washing machine or sweep and drag integrated machine etc.. For the convenience of explanation, the specific structure of cleaning equipment 100 is described with dust collector as example, other equipment can be referred to adaptability implementation.

[0037] Specifically, please refer to Figures 1 to 3In the embodiment, the cleaning device 100 comprises a cleaning main body 1, an airflow generating device 2, a second cover 3 and a fumigation module 4. The airflow generating device 2 is arranged on the cleaning main body 1 and comprises an airflow generator 21 and a first cover 22 arranged on the periphery of the airflow generator 21. The second cover 3 is arranged on the periphery of the first cover 22 and is provided with a ventilation hole 31 adapted to communicate with the outside. An airflow channel is formed between the ventilation hole 31 and the airflow generating device 2. The fumigation module 4 is arranged in the airflow channel. The airflow generated by the airflow generating device 2 flows into the airflow channel and at least partially flows through the fumigation module 4 and then flows out of the ventilation hole 31.

[0038] In the embodiment, the airflow generating device 2 can form a negative pressure in the cleaning main body 1, so that the external dirt is sucked into the cleaning main body 1 through the dust suction port on the cleaning main body 1. The first cover 22 is arranged on the periphery of the airflow generator 21, and the second cover 3 is further arranged on the periphery of the first cover 22. The double covers can effectively reduce the noise generated by the airflow generator 21 during operation. The fumigation module 4 is arranged in the airflow channel between the airflow generating device 2 and the ventilation hole 31. The airflow generated by the airflow generating device 2 can flow through the fumigation module 4 and then flow into the user's environment through the ventilation hole 31. Therefore, the cleaning device 100 not only has a small noise during operation, but also leaves a fragrance in the user's environment after the cleaning work is completed, which can better improve the user's experience.

[0039] The cleaning main body 1 comprises a shell, a dust cup assembly arranged in the shell, a filter assembly and the like. A dust suction port is arranged on one side of the shell and is in communication with the dust cup assembly. The airflow generating device 2 is in communication with the filter assembly. When the airflow generating device 2 is started, a negative pressure is formed in the dust cup assembly. The dirt enters the dust cup assembly from the dust suction port under the action of the airflow and is filtered by the filter assembly. The dirt is stored in the dust cup of the dust cup assembly. The clean airflow flows to the airflow generating device 2, flows to the airflow channel through the airflow generating device 2, and then flows to the outside through the ventilation hole 31, thereby forming an airflow circulation during the operation of the cleaning device 100. The fumigation module 4 is arranged in the airflow channel, so that the fragrance volatilized from the fumigation module 4 is carried out by the clean airflow, and the use environment of the cleaning device 100 is filled with fragrance.

[0040] In this embodiment, the airflow generating device 2 can be configured as an axial flow fan, a centrifugal fan, or a vacuum pump, etc., to extract air from the dust cup assembly, creating a negative pressure within the dust cup assembly, thereby sucking some dirt into the dust cup assembly through the dust suction port. Preferably, the airflow generating device 2 is configured as an axial flow fan. The housing is generally cylindrical, the dust cup assembly is coaxially arranged with the housing, the impeller of the axial flow fan forms the airflow generator 21, and the fan housing of the axial flow fan forms the first cover 22. The axial direction of the axial flow fan is coaxial with the housing, and the dust cup assembly and the airflow generating device 2 are arranged sequentially along the axial direction of the housing. The dust cup assembly is defined as the front end, and the airflow generating device 2 is defined as the rear end, i.e., the dust cup assembly and the airflow generating device 2 are located in front of the airflow generating device 2. The dust suction port is located on one side of the dust cup assembly, near the front end, and the vent 31 is located near the rear end of the airflow generating device 2, so that airflow can be drawn in through the front dust suction port and discharged through the rear vent 31, resulting in smoother circulation.

[0041] It is understood that there are many ways to establish a connection channel between the airflow generator 21 and the vent 31. For example, a guide pipe can be extended from the side of the airflow generator 21 and connected to the vent 31; or a through hole can be opened in the first cover 22 and connected to the vent 31 through the through hole. This allows the clean air discharged from the airflow generator 21 to be discharged through the vent 31 more effectively.

[0042] Preferably, combined Figure 2 and Figure 3 As shown, a sandwich is formed between the first cover 22 and the second cover 3, and the aroma module 4 is located in the sandwich and is connected to the air outlet of the air flow generator 21 and the ventilation hole 31. The airflow discharged from the air outlet of the air flow generator 21 can flow into the sandwich through the holes of the first cover 22, or the airflow discharged from the air outlet of the air flow generator 21 can enter the sandwich through the aroma module 4 and then be discharged from the ventilation hole 31, or, in combination with Figure 2 The dotted arrows in the middle represent the direction of airflow. Part of the airflow discharged from the air outlet of the airflow generator 21 flows into the interlayer through the holes on the first cover 22, and the other part flows into the interlayer from the aromatherapy module 4. Under the repeated impact of the airflow in the interlayer, the fragrance in the aromatherapy module 4 can be better volatilized and filled in the interlayer, and then discharged from the ventilation holes 31 with the airflow, so that the fragrance can better enter the use environment.

[0043] Specifically, if Figure 3As shown in FIG, the aroma module 4 includes a receiving chamber 41 and an aroma component 42. The receiving chamber 41 is located within the interlayer and communicates with the air outlet of the airflow generator 21 and the vent 31. The aroma component 42 is located within the receiving chamber 41. The aroma component 42 is replaceable and can be configured as aroma tablets, aroma cream, or aroma powder. Users can replace the aroma component 42 according to their personal preferences. The receiving chamber 41 secures the aroma component 42 within the interlayer, making it easy to remove, place, or replace the aroma component 42.

[0044] The accommodating cavity 41 may be fixed to the first cover 22, and / or the accommodating cavity 41 may be fixed to the second cover 3. The accommodating cavity 41 may be detachably disposed from the first cover 22 or the second cover 3.

[0045] Preferably, if Figure 3 and Figure 4 As shown in the figure, the accommodating chamber 41 is provided on the outer periphery of the first housing 22 and is integrally formed with the first housing 22. After the second housing 3 is removed from the first housing 22, the aromatherapy module 4 can be better exposed, making it easier to replace the aromatherapy element 42 in the aromatherapy module 4. Furthermore, the integral formation of the accommodating chamber 41 and the first housing 22 reduces the number of assembly parts and prevents relative movement between the aromatherapy module 4 and the first housing 22, effectively reducing abnormal noise during operation of the airflow generator 21.

[0046] It is understood that the shape and size of the accommodating cavity 41 are not specifically limited and can be reasonably set according to the size of the cleaning device 100 and the size of the interlayer between the first cover 22 and the second cover 3. Figure 4 As shown in FIG, the accommodating cavity 41 includes a accommodating groove 411 protruding from the outer periphery of the first housing 22. The accommodating groove 411 is generally square in shape, having two first groove walls extending axially along the first housing 22 and two second groove walls extending circumferentially along the first housing 22. The two first groove walls and the two second groove walls are connected to form a mounting space for the aromatherapy component 42. The opening of the accommodating groove 411 faces the second housing 3, and at least a portion of the bottom of the accommodating groove 411 is hollowed out to communicate with the outlet of the airflow generator 21. At least a portion of the airflow exhausted from the outlet of the airflow generator 21 can enter the accommodating groove 411 through the hollowed-out bottom of the accommodating groove 411, carrying fragrance volatilized from the aromatherapy component 42 into the interlayer, and then exit the cleaning device 100 through the ventilation hole 31.

[0047] Moreover, if Figure 4As shown in Figs. 11 and 12, the elastic abutting member 43 is arranged at one side of the accommodating groove 411, and is used to abut against one side of the incense member 42 to limit the incense member 42 in the accommodating groove 411, so as to avoid the incense member 42 from being taken out of the accommodating groove 411 during the operation of the cleaning device 100, and to affect the incense effect. Specifically, the elastic abutting member 43 comprises an elastic roller and a spring connected with the elastic roller, and the elastic roller is movably arranged on one of the second groove walls of the accommodating groove 411. When the incense member 42 is not placed in the accommodating groove 411, the elastic roller is arranged protruding from the second groove wall, and the spring is in a natural extension state; when the incense member 42 is placed in the accommodating groove 411, the incense member 42 can abut against the elastic roller to drive the elastic roller to compress the spring, and at the same time, the incense member 42 is pressed and fixed in the accommodating groove 411 by the reverse extension force of the spring, so that the incense member 42 is more convenient to take out and replace, and the incense member 42 is not easy to fall off.

[0048] Further, a limiting rib is arranged on the other second groove wall of the accommodating groove 411, so that the limiting effect on the incense member 42 is better. Moreover, a avoiding opening is arranged at the slot opening of the accommodating groove 411, and when the incense member 42 is placed in the accommodating groove 411, part of the incense member 42 can protrude from the slot opening of the accommodating groove 411, and the avoiding opening makes the incense member 42 more convenient to hold when taking out and placing, so that the taking out and placing is more easy.

[0049] It can be understood that if the air outlet end of the airflow generator 21 is only communicated with the interlayer through the accommodating groove 411, the air exhaust amount will be obviously affected, and the working efficiency of the entire cleaning device 100 will be affected. Therefore, as shown in Figs. 13 and 14, the air outlet hole 221 is further arranged on the first cover body 22, the air outlet hole 221 is communicated with the air outlet end of the airflow generator 21 and the ventilation hole 31 through the interlayer, and the air outlet hole 221 and the accommodating groove 411 are arranged in a spaced manner along the circumference of the first cover body 22. Figure 3 and Figure 5 The airflow exhausted from the air outlet end of the airflow generator 21 is partially introduced into the interlayer through the accommodating groove 411, and the other part is introduced into the interlayer through the air outlet hole 221, and under the action of the long and narrow space of the interlayer, the airflow introduced into the interlayer can flow in a detour manner, and impact on the incense member 42, so that the incense factor of the incense member 42 can be better carried away with the airflow, and the incense effect is better.

[0050] Since the incense member 42 has a limited service life, it needs to be replaced or added frequently. Preferably, the first cover body 22 and the second cover body 3 are arranged in a detachable connection manner, so as to facilitate the disassembly of the second cover body 3, thereby facilitating the taking out and placing of the incense member 42. Specifically, the mounting portion is arranged on the first cover body 22, and the matching portion is arranged on the second cover body 3, and the mounting portion and the matching portion are clamped and matched to fix the second cover body 3 on the first cover body 22, so as to facilitate the disassembly of the second cover body 3.

[0051] Further preferably, in combination Figure 3 and Figure 5 As shown in the figure, the mounting portion comprises a clamping groove 222 provided on the outer circumferential side of the first cover body 22, the clamping groove 222 is arranged along the circumferential direction of the first cover body 22 and is provided with a notch 223 on one side along the axial direction, specifically, the notch 223 is arranged towards the rear end of the first cover body 22; the cooperating portion comprises a clamping protrusion 32 provided on the inner side wall of the second cover body 3, the clamping protrusion 32 can extend into the clamping groove 222 from the notch 223 and rotate by a certain angle along the circumferential direction to be clamped with the clamping groove 222. Among them, the shape of the second cover body 3 is matched with the shape of the first cover body 22, and both are approximately cylindrical. The front end face of the second cover body 3 along the axial direction is arranged in an open manner. When the second cover body 3 is mounted on the first cover body 22, the front end of the second cover body 3 can be axially sleeved on the outside of the first cover body 22. At this time, the clamping protrusion 32 is aligned with the notch 223 of the clamping groove 222, so that when the second cover body 3 is sleeved, the clamping protrusion 32 can extend into the inside of the clamping groove 222, and then the second cover body 3 is rotated, so that the clamping protrusion 32 on the second cover body 3 is misaligned with the notch 223 of the clamping groove 222, thereby clamping the second cover body 3 on the first cover body 22; when it is necessary to disassemble the second cover body 3, the second cover body 3 is reversely rotated so that the clamping protrusion 32 of the second cover body 3 is opposite to the notch 223 of the clamping groove 222 on the first cover body 22, and then the second cover body 3 is axially removed. The disassembly operation of the second cover body 3 is simple and convenient, so it is also more convenient to replace the incense fumigating piece 42.

[0052] Preferably, the clamping groove 222 can be provided with a plurality of clamping grooves 222, and the plurality of clamping grooves 222 are uniformly and spacedly arranged along the circumferential direction of the first cover body 22; the clamping protrusion 32 is also provided with a plurality of clamping protrusions 32, and the plurality of clamping protrusions 32 and the plurality of clamping grooves 222 are one-to-one corresponding, so that the connection of the second cover body 3 and the first cover body 22 is more stable.

[0053] Among them, in an embodiment, in combination Figures 1 to 3 As shown in the figure, the cleaning device 100 further comprises a handle structure 5, the handle structure 5 is connected to one side of the first cover body 22 and is misaligned with the air outlet hole 221 along the circumferential direction of the first cover body 22, and the handle structure 5 is connected to the air flow generating device 2 to support, so as to support the relatively heavy part of the cleaning device 100, so that the stability of the cleaning device 100 is better. And the handle structure 5 will not block the air outlet hole 221, and will not affect the air exhaust capacity of the air flow generating device 2, so that the cleaning effect of the cleaning device 100 is better.

[0054] Further, a gap is formed between the end of the first cover 22 along the axial direction away from the cleaning body 1 (i.e. the rear half of the first cover 22) and the handle structure 5, and at least part of the second cover 3 is located in the gap, i.e. at least part of the second cover 3 can be inserted into the gap between the first cover 22 and the handle structure 5, so that the first cover 22, the second cover 3 and the handle structure 5 at least partially overlap, the structure is more compact, and the volume of the entire cleaning device 100 can be smaller. The ventilation hole 31 is arranged in a staggered manner along the circumferential direction of the second cover 3, and the handle structure 5 does not affect the exhaust amount of the air flow generating device 2, so that the cleaning device 100 is smaller in size and better in dust suction effect.
