[0040] 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.. The cleaning equipment 100 can be used to clean the surface (such as ground, wall surface) to be cleaned. For the convenience of explanation, the specific structure of the cleaning equipment 100 is described below, taking the cleaning equipment 100 as a dust collector and mainly used for cleaning ground as an example, other equipment can be adapted.

[0041] Specifically, please refer to Figures 1 to 3 In the embodiment, the cleaning equipment 100 includes a device main body 1, a suction device, a release module 2 and a shielding cover 3; the suction device is arranged in the device main body 1; the release module 2 is arranged on the device main body 1 and located in the air flow channel formed by the suction device; the shielding cover 3 is movably arranged on the device main body 1 and has a first working position and a second working position; wherein, when the shielding cover 3 is in the first working position, the shielding cover 3 is arranged outside the release module 2, and an air gap suitable for connecting the outside and the air flow channel is formed between the shielding cover 3 and the device main body 1; when the shielding cover 3 is in the second working position, the release module 2 is exposed.

[0042] In the embodiment, the suction device can form a suction air flow, external dirt can be brought into the device body 1 under the action of the suction air flow for storage, and clean air flow filtered by the device body 1 can be discharged through the suction device to be discharged from the device body 1 into the user's use environment (such as a room); by setting the release module 2 in the air flow channel formed by the suction device, the release module 2 can release essential oil or incense, so that the air flow discharged into the room carries the fragrance, and the indoor environment is fresher, which can effectively improve the user experience; and the release module 2 is provided with a shielding cover 3 on the outside, and the shielding cover 3 is moved relative to the device body 1, so that the shielding cover 3 has a first working position shielding the release module 2, and the release module 2 is not exposed on the outside of the device body 1 when the cleaning device 100 is working normally, so as to better protect the release module 2, and when the shielding cover 3 is in the second working position, the release module 2 can be exposed, so as to facilitate replacement of the release module 2 and supplement of the release fragrance by the user.

[0043] The device body 1 can be provided with a dirt storage tank, a dust suction port is arranged on one side of the device body 1, the dirt storage tank is communicated with the dust suction port and the air inlet end of the suction device, the suction device can be provided with a fan, and an air outlet is arranged on the device body 1. When the cleaning device 100 normally performs cleaning work, the fan is started, so that a negative pressure is formed in the dirt storage tank, external dirt can enter the dirt storage tank from the dust suction port, and a filtering structure can be further arranged at the air outlet of the dirt storage tank. The airflow carrying dirt is discharged from the air outlet after being filtered by the filtering structure, enters the suction device, and then flows to the air outlet of the device body 1 through the air outlet end of the suction device, is discharged into the user's room, and forms a suction circulating air flow. The air outlet of the dirt storage tank, the suction device, the air outlet of the device body 1, and the path for air flow to flow between the air outlet and the outside form the air flow channel.

[0044] It can be understood that the release module 2 can be located at any position of the air flow channel formed by the suction device. For example, the release module 2 can be located between the air outlet of the dirt storage tank and the air inlet end of the suction device, or the release module 2 can be located between the air outlet end of the suction device and the air outlet of the device body 1, or the release module 2 is located on the path for the air outlet to communicate with the outside, so that the fragrance released by the release module 2 can be better brought into the user's room, and the incense effect is better.

[0045] Preferably, the release module 2 is provided on the outer shell of the device body 1, and a wind gap is formed between the shielding cover 3 and the outer shell of the device body 1, so that the airflow from the air outlet of the device body 1 can flow through the release module 2 and then be discharged from the wind gap. Figure 3 and Figure 4 As shown, the release module 2 includes a mounting slot 21 and an aromatherapy block 22. The aromatherapy block 22 is detachably fixed in the mounting slot 21. The aromatherapy block 22 can be a solid or powdered fragrance that can automatically release fragrance and needs to be replaced or replenished after a certain period of use. When the shielding cover 3 is in the first working position, the shielding cover 3 completely covers the release module 2 so that the release module 2 is not exposed on the outside of the cleaning device 100. On the other hand, it can better protect the release module 2 and prevent the release module 2 from falling off. When the shielding cover 3 is in the second working position, the release module 2 can be exposed on the outside of the device body 1, making it convenient for the user to replenish or replace the aromatherapy block 22.

[0046] It can be understood that when replacing the release module 2, in one embodiment, the shielding cover 3 can be completely removed so that the shielding cover 3 is separated from the device body 1, and then the release module 2 is replaced, and then the shielding cover 3 is installed on the device body 1.

[0047] Preferably, when replacing the release module 2, the shielding cover 3 can be moved to expose the release module 2 for replacement, while keeping the shielding cover 3 on the device body 1, so that it is more convenient to operate when opening and closing the shielding cover 3.

[0048] Specifically, combined Figures 4 to 6 As shown, a snap-fit ​​portion 31 is provided on the shielding cover 3, and a first matching portion 11 and a second matching portion 12 are provided on the device body 1. When the snap-fit ​​portion 31 is snap-fitted with the first matching portion 11, the shielding cover 3 is in the first working position, and the shielding cover 3 is completely covered on the outside of the release module 2; when the snap-fit ​​portion 31 is snap-fitted with the second matching portion 12, the shielding cover 3 is in the second working position, so that the shielding cover 3 is still connected to the device body 1, and the release module 2 can be exposed to the outside, thereby facilitating the processing of the release module 2.

[0049] Preferably, combined Figures 4 to 6As shown in the figure, the clamping part 31 comprises a clamping protrusion 311 protruding from the inner side of the cover 3, the first matching part 11 comprises a first clasp 111 arranged on the device body 1, and the second matching part 12 comprises a second clasp 121 arranged on the device body 1. When the cover 3 is in the first working position, the cover 3 is moved in the first direction relative to the device body 1 under the action of an external force, so that the clamping protrusion 311 can pass the first clasp 111 and be clamped with the second clasp 121 to be kept in the second working position. It can be understood that the cover 3 can be manually moved by a person, or the cover 3 can be directly or indirectly driven by a driving component to move relative to the device body 1. In this embodiment, preferably, the cover 3 is manually moved by a person, and the structure is simpler. By manually applying a force to the cover 3, the cover 3 is driven to move in the first direction along the device body 1, so that the clamping protrusion 311 on the cover 3 can be disengaged from the first clasp 111. When the cover 3 is continuously moved in the first direction, the cover 3 is moved into position when the clamping protrusion 311 is clamped with the second clasp 121, which can prevent the cover 3 from falling off the device body 1 on the one hand, and can make the release module 2 completely exposed on the other hand.

[0050] In the first direction, the clamping force of the clamping protrusion 311 and the first clasp 111 is smaller than the clamping force of the clamping protrusion 311 and the second clasp 121. When a user pushes the cover 3 in the first direction by hand, the clamping protrusion 311 can be disengaged from the first clasp 111 under a certain large force. When the clamping protrusion 311 and the second clasp 121 are continuously clamped, the cover 3 is not easy to fall off the device body 1 due to the relatively large clamping force of the clamping protrusion 311 and the second clasp 121, so as to be kept in the second working position.

[0051] Furthermore, in an embodiment, the first clasp 111 and the second clasp 121 can not be arranged in the same way.

[0052] Further, as Figure 4As shown in , a first guide surface 112 is provided on the first buckle 111. When the shielding cover 3 is moved along the first direction by an external force, the engaging boss 311 moves along the first guide surface 112 toward the second buckle 121 and forms a stop fit with the second buckle 121 along the first direction. The guiding effect of the first guide surface 112 makes it easier for the engaging boss 311 to disengage from the first buckle 111. As a result, the engaging boss 311 can stop fit with the second buckle 121 after passing over the first buckle 111, making it difficult for the second buckle 121 to disengage from the engaging boss 311, and the shielding cover 3 is difficult to fall off from the device body 1.

[0053] Furthermore, the first clip 111 and the second clip 121 are both configured as elastic clips. When the snap-fitting boss 311 and the first clip 111 and the second clip 121 are disengaged, the first clip 111 and the second clip 121 can be elastically deformed to better separate from the snap-fitting boss 311, which can save effort when pushing the shielding cover 3.

[0054] Furthermore, the shielding cover 3 has a disassembly position relative to the device body 1. When the shielding cover 3 is in the second working position and continuously subjected to an external force in the first direction, the shielding cover 3 can be moved from the second working position toward the disassembly position, allowing the shielding cover 3 to be completely removed from the device body 1 for easy cleaning and maintenance. When the shielding cover 3 is moved in the second direction by an external force, the shielding cover 3 can be moved from the disassembly position sequentially toward the second working position and the first working position, wherein the second direction is opposite to the first direction. That is, when the disassembled shielding cover 3 needs to be reinstalled on the device body 1, the shielding cover 3 can be pushed in the opposite direction, so that the engaging protrusion 311 on the shielding cover 3 can pass over the second latch 121 and engage with the first latch 111 to shield the release module 2.

[0055] Among them, such as Figure 5 As shown in the figure, in order to facilitate the installation of the shielding cover 3 on the device body 1, a second guide surface 122 is provided on the second buckle 121, and a third guide surface 113 is provided on the first buckle 111; when the shielding cover 3 is moved along the second direction by an external force, the snap-fitting boss 311 can move along the second guide surface 122 to pass over the second buckle 121, and move along the third guide surface 113 to pass over the first buckle 111, and snap-fit ​​with the first buckle 111, so that the shielding cover 3 is more labor-saving and smoother when installed.

[0056] The first guide surface 112, the second guide surface 122 and the third guide surface 113 include but are not limited to inclined surfaces, circular arc surfaces, or stepped planes, etc. Preferably, the first guide surface 112 and the third guide surface 113 are arranged as smooth circular arc surfaces.

[0057] It should be noted that, in the normal use of the cleaning device 100, the dust suction port is located at the front end of the device body 1, and the shielding cover 3 is arranged close to the rear end of the device body 1. The first direction can refer to the direction from front to back along the device body 1, and the second direction refers to the direction from back to front along the device body 1. The shielding cover 3 can move in the front-back direction to open and close the release module 2. In the present utility model, the description of the relevant orientation can be referred to.

[0058] In combination with the above, Figure 3 and Figure 4 As shown in the above, the device body 1, specifically the housing of the device body 1, can be provided with a first air outlet 13 and a second air outlet 14. The airflow discharged from the suction device can flow outward from the first air outlet 13 and the second air outlet 14. The first buckle 111 includes a first elastic arm 1111 and a first boss 1112 arranged on the first elastic arm 1111. The first elastic arm 1111 extends from the periphery of the first air outlet 13 in the second direction towards the inner side thereof. The first guide surface 112 and the third guide surface 113 are arranged opposite to the first boss 1112. In the normal operation of the cleaning device 100, the first boss 1112 abuts against the rear side of the clamping protrusion 311 to limit the rearward movement of the shielding cover 3, thereby fixing the shielding cover 3 at the first working position. The second buckle 121 includes a second elastic arm 1211 and a second boss 1212 arranged on the second elastic arm 1211. The second elastic arm 1211 extends from the periphery of the second air outlet 14 in the first direction towards the inner side thereof. The second guide surface 122 is arranged on the side of the second boss 1212 opposite to the first buckle 111. In the replacement of the release module 2, the second boss 1212 abuts against the rear side of the clamping protrusion 311 to limit the rearward movement of the shielding cover 3, thereby fixing the shielding cover 3 at the second working position.

[0059] Further, a guide sliding groove 15 is arranged on the first surface of the device body 1, the guide sliding groove 15 is arranged along the first direction, and the first matching part 11 and the second matching part 12 are arranged in the guide sliding groove 15; the shielding cover 3 is provided with a guide sliding block 32, the guide sliding block 32 is clamped on the outside of the guide sliding groove 15 along the first direction, and the guide sliding block 32 and the guide sliding groove 15 form a stop cooperation along the direction perpendicular to the first surface, so that the shielding cover 3 is more stable when moving along the front-back direction of the device body 1 and is not easy to shake.

[0060] Specifically, as shown in Figure 5 The guide sliding groove 15 includes two guide groove walls arranged opposite along the up-down direction of the device body 1, and each guide groove wall extends along the front-back direction of the device body 1. The guide sliding block 32 includes two sliding walls arranged opposite along the up-down direction, and each sliding wall extends along the front-back direction of the device body 1, and the two sliding walls are respectively slidably arranged on the side away from the two guide groove walls, so that the shielding cover 3 can be limited in the up-down direction of the device body 1 by the two guide groove walls.

[0061] Further, a protruding rib is arranged on the side away from the two guide groove walls, and the two sliding walls are slidably arranged in the protruding rib and form an abutting cooperation along the inward direction (i.e. the left-right direction) of the device body 1, so that the displacement of the shielding cover 3 along the left-right direction is limited by the guide sliding groove 15, and the shielding cover 3 can be completely limited on the device body 1.

[0062] Moreover, the release module 2 is provided with two, and the two release modules 2 are arranged on the two sides of the air outlet end of the suction device; the shielding cover 3 is provided with two, and the two shielding covers 3 are arranged one by one corresponding to the two release modules 2. Preferably, the two shielding covers 3 are located on the left and right sides of the device body 1, so that the discharge efficiency of the airflow is higher, and the working efficiency of the cleaning device 100 is higher. Moreover, the fragrance released by the release module 2 is more balanced, so that the incense effect in the room is better.

[0063] The above is only the preferred embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure made by using the content of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection range of the present application.
