Description

Technical Field

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

[0002] With the development of social economy and the improvement of people's living standards, cleaning equipment such as floor scrubbers and vacuum cleaners are increasingly used in people's daily lives due to their high cleaning efficiency, time-saving and labor-saving advantages.

[0003] Most models of floor scrubbers on the market require the suction channel on the sewage tank cover to pump the inner cavity of the sewage tank into a negative pressure state so that the ground sewage is sucked into the sewage tank. In addition, in order to prevent water from entering electrical components such as the suction motor, a filter component will be set in the suction channel.

[0004] However, after cleaning the sewage tank, the user may forget to reinstall the filter assembly, and the sewage may be sucked into the suction motor, causing damage to the main motor. Utility Model Content

[0005] In view of the above problems, the utility model provides a sewage tank, a cleaning device and a cleaning system, which can remind the user to install the filter component back to the box cover to avoid damage to the suction device when the cleaning device is running without the filter component.

[0006] The utility model provides a sewage tank for cleaning equipment, the cleaning equipment comprises a body, and the sewage tank comprises: a box body, the box body defines a accommodating cavity; a box cover assembly, comprising a box cover and an in-place trigger device, the box cover is arranged on the box body, the box cover defines a suction channel connected to the accommodating cavity, the box cover also defines an activity space, and the in-place trigger device can be movably arranged in the activity space; a filter assembly, the filter assembly is detachably arranged in the suction channel, wherein, when the filter assembly is installed to the suction channel, the filter assembly abuts against the in-place trigger device and drives the in-place trigger device to retract into the activity space, and when the filter assembly is separated from the suction channel, the in-place trigger device extends from the activity space and prevents the sewage tank from being installed to the body.

[0007] According to the sewage tank of the utility model, the in-place trigger device is movably arranged in the activity space. When the user removes the filter assembly from the box cover for cleaning, replacement, or performs any other operation that causes the filter assembly to be separated from the box cover, and the filter assembly is not reinstalled on the box cover and the sewage tank is installed back to the machine body, the in-place trigger device can extend from the activity space and prevent the sewage tank from being installed on the machine body, thereby reminding the user that the filter assembly is not reinstalled on the box cover. In this way, it can be avoided that when the cleaning device is running without the filter assembly, the sewage tank cannot suck water and the suction device is damaged by water, thereby improving the reliability of the cleaning device and helping to improve the user experience.

[0008] In some embodiments, the activity space extends vertically, the top wall of the box cover has an opening connected to the activity space, and the in-position trigger device performs telescopic movement through the opening. In this way, the movement form of the in-position trigger device is relatively simple and easy to implement.

[0009] In some embodiments, the box cover has a mounting platform located on the periphery of the suction channel, at least a portion of the structure of the filter assembly is embedded in the mounting platform, and the opening is provided on the mounting platform.

[0010] In this way, when the filter assembly is embedded in the installation sink, it can be installed in the suction channel at the same time, and can also directly cooperate with the in-place trigger device, for example, covering the upper side of the in-place trigger device. The overall structure is relatively simple, eliminating the need to set an intermediate transmission structure between the filter assembly and the in-place trigger device when the suction channel and the activity space are far apart, which makes the overall structure complicated; in addition, when the filter assembly is installed in place, the in-place detection device can be concealed inside the box cover, improving the consistency of the appearance and making the appearance more beautiful.

[0011] In some embodiments, the tank cover is provided with a handle, and the handle is located on the side of the sewage tank facing away from the body; the activity space and the in-place trigger device are both located on the side of the suction channel facing the handle.

[0012] Because when the sewage tank is installed on the fuselage, the position near the handle is usually the last part of the sewage tank to enter the accommodating space of the fuselage, arranging the in-place trigger device near the handle can not only reduce the collision between the in-place trigger device and the fuselage, but also prevent the in-place trigger device from being stuck in a recess on the fuselage that is provided to cooperate with the sewage tank or to realize other functions, resulting in failure of the function of the in-place trigger device.

[0013] In some embodiments, the in-position trigger device includes: a stopper, which is movably disposed in the activity space to extend from or retract into the activity space; and a driving member, which is in transmission cooperation with the stopper to drive the stopper to move.

[0014] Thus, the in-position trigger device has a simple structure and is easy to manufacture and assemble.

[0015] In some embodiments, the driving member is configured to always exert a force on the stopper toward the opening of the activity space.

[0016] In this way, when the filter assembly is separated from the box cover, the driving member can automatically drive the stopper to extend.

[0017] In some embodiments, the driving member includes an elastic member.

[0018] Thus, when the filter assembly is mounted on the box cover, the filter assembly drives the stopper to retract into the active space, the stopper compresses the drive member, and the drive member stores energy. When the filter assembly is removed from the box cover, the drive member drives the stopper to extend out of the active space. In addition, the cost of the drive member is low and the service life is long.

[0019] In some embodiments, a limiting structure is provided on the box cover, and when the stopper extends out from the activity space, the limiting structure cooperates with the stopper in a limiting manner.

[0020] In this way, it is possible to prevent the stopper from being separated from the activity space when moving in the activity space, thereby ensuring the reliability of the in-position trigger device.

[0021] In some embodiments, the stop member includes: a first section and a second section, the first section and the second section are arranged sequentially and connected along the direction of movement, the first section is located on the side of the second section away from the driving member, the size of the first section perpendicular to the direction of movement of the stop member is smaller than the size of the second section perpendicular to the direction of movement of the stop member, the limiting structure is provided at the opening of the activity space, and when the stop member extends from the activity space, the limiting structure abuts against the second section.

[0022] In this way, it can ensure that the first section can extend from the activity space to prevent the sewage tank from being installed on the fuselage without installing the filter assembly, and the limiting structure can cooperate with the second section to prevent the stopper from leaving the activity space.

[0023] In some embodiments, the end face of the stopper away from the driving member is parallel to the surface where the opening of the activity space is located; when the filter assembly drives the stopper to retract into the activity space, the end face of the stopper away from the driving member is flush with the surface where the opening of the activity space is located.

[0024] In this way, on the one hand, it can be ensured that the filter assembly can be stably embedded in the predetermined installation position, and on the other hand, it can be ensured that the filter assembly is always in contact with the stopper, ensuring the sensitivity of the trigger device in place when the filter assembly is separated from the box cover.

[0025] In some embodiments, the filter assembly includes: a mounting frame, which is detachably matched with the box cover, and when the filter assembly is installed to the suction channel, the mounting frame abuts against the in-place trigger device; a filter element, which is arranged on the mounting frame and is located in the suction channel.

[0026] In this way, the installation frame can be used in conjunction with the in-place trigger device to achieve in-place detection of the filter assembly.

[0027] In some embodiments, an outwardly protruding abutting portion is provided on the periphery of the mounting frame, and the abutting portion abuts against the in-position trigger device.

[0028] In this way, the matching mode between the mounting frame and the in-place trigger device is simple and reliable, and easy to manufacture and implement.

[0029] In some embodiments, one of the mounting frame and the box cover is provided with a fixing structure, and the other is provided with a fixing matching structure. When the mounting frame is installed to the box cover, the fixing structure matches with the fixing matching structure to fix the mounting frame.

[0030] In this way, when the filter assembly is installed on the box cover, the installation stability of the filter assembly can be guaranteed, and the filter assembly can be prevented from being unstable under the reaction force of the in-place trigger device, thereby further improving the reliability of the filter assembly.

[0031] In some embodiments, a fitting gap is formed between the box cover and the mounting frame, the side wall of the mounting frame is provided with a fixing protrusion, the fixing protrusion constitutes the fixing structure, the inner wall of the suction channel is provided with a fitting protrusion, the fitting protrusion constitutes the fixed fitting structure, the protrusion heights of the fixing protrusion and the fitting protrusion are both smaller than the width of the fitting gap, when the filter assembly is installed to the suction channel, the fixing protrusion is located on the inner side of the fitting protrusion, and the fixing protrusion and the fitting protrusion interfere with each other in the extension direction of the suction channel.

[0032] In this way, when installing the filter assembly to the box cover, a certain pressure can be applied to the installation frame to move the fixing protrusion from the upper side of the mating protrusion to the lower side, and achieve a snap fit between the two to ensure the installation stability of the filter assembly. In addition, the fixing method of the installation frame is relatively simple and easy to manufacture and assemble.

[0033] The utility model also provides a cleaning device, comprising: a body; a cleaning component, used to clean a surface to be cleaned; and a sewage tank as described in the first aspect of the utility model, wherein the sewage tank is arranged on the body and is constructed to receive sewage absorbed by the cleaning component.

[0034] The cleaning device of the utility model can remind the user to install the filter assembly when the user fails to reinstall the filter assembly on the box cover by providing the above-mentioned sewage tank. This can avoid the situation where the suction device is damaged when the cleaning device is running without the filter assembly, thereby improving the reliability of the cleaning device and helping to improve the user experience.

[0035] The utility model further provides a cleaning system, comprising: the cleaning device described in the second aspect of the utility model; and a cleaning base station, wherein the cleaning base station is at least configured to clean a cleaning component of the cleaning device.

[0036] According to the cleaning system of the present invention, by providing the cleaning device of the above embodiment, the reliability of the system can be improved, which is beneficial to improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0053] With the development of social economy and the improvement of people's living standards, cleaning equipment such as floor scrubbers and vacuum cleaners are increasingly used in people's daily lives due to their high cleaning efficiency, time-saving and labor-saving advantages. Most models of floor scrubbers on the market need to use the suction channel on the sewage tank cover to pump the inner cavity of the sewage tank into a negative pressure state so that the ground sewage can be sucked into the sewage tank, and in order to prevent electrical components such as the suction motor from getting water, a filter component will be set in the suction channel. However, after cleaning the sewage tank, the user may forget to reinstall the filter component. The installation of the filter component may result in the failure to suck water, and the sewage may be sucked into the suction motor, causing damage to the main motor.

[0054] In view of this, the utility model provides a sewage tank, cleaning equipment and cleaning system, wherein the in-place trigger device of the filter component is movably arranged in the activity space, and when the user removes the filter component from the box cover for cleaning, replacement or any other operation that causes the filter component to be separated from the box cover, and when the filter component is not reinstalled on the box cover, that is, the sewage tank is installed back on the machine body, the in-place trigger device can extend from the activity space and prevent the sewage tank from being installed on the machine body, thereby reminding the user that the filter component is not reinstalled on the box cover. In this way, when the cleaning equipment is running without the filter component, it can be avoided that the sewage tank cannot suck up water and the suction device is damaged by water, thereby improving the reliability of the cleaning equipment and helping to improve the user experience.

[0055] Combine the following Figure 1-Figure 5 The sewage tank 100 according to the first embodiment of the utility model is described.

[0056] The sewage tank 100 of this embodiment can be used for cleaning equipment, and the cleaning equipment can be a floor scrubber, a cleaning robot, a vacuum cleaner with a mopping function, etc. The cleaning equipment can be a household cleaning equipment or an industrial cleaning equipment, and this application does not impose any restrictions on this.

[0057] The cleaning device may include a body and a cleaning component. The body may be used to accommodate a sewage tank 100, which may be detachably mounted on the body. The body may also provide an installation platform and support for other components of the cleaning device. The cleaning component may be disposed at the bottom of the body. The cleaning component may move along a surface to be cleaned and clean the surface to be cleaned. For example, the cleaning component may include a roller brush, a side brush, etc. The side brush may gather dirt around the cleaning component to the center of the cleaning component, and the roller brush may suck in dirt, sewage, etc.

[0058] refer to Figure 1 and Figure 2 The sewage tank 100 may include: a tank body 1 , a tank cover assembly 2 , and a filter assembly 5 .

[0059] Among them, the box body 1 can define a accommodating chamber 11, and the accommodating chamber 11 can be used to store sewage, dirt, etc. sucked in during the operation of the cleaning equipment. The box body 1 can be cylindrical, square cylindrical, or irregular in shape. The shape of the box body 1 is adapted to the shape of the space on the fuselage for accommodating the box body 1, and the top of the box body 1 can be open to form a sewage outlet. The box body 1 also has a sewage inlet channel 12, which extends along the height direction of the box body 1, and the sewage inlet channel 12 has a connecting port 121 connected to the accommodating chamber 11. For example, a channel partition is provided in the accommodating chamber 11, and the channel partition is in the shape of a cylinder with both ends open. The channel partition extends along the height direction of the box body 1 and defines the sewage inlet channel 12, and the connecting port 121 is located at the top of the channel partition.

[0060] The box cover assembly 2 may include a box cover 21 and an in-position trigger device 22. The box cover 21 is arranged on the box body 1. For example, the box cover 21 is arranged at the sewage outlet of the box body 1 to achieve sealing of the sewage outlet. When the sewage in the box body 1 reaches the allowable capacity or there are other situations where sewage needs to be dumped, the box cover 21 can be removed from the box body 1 and the sewage can be dumped and discharged from the sewage outlet.

[0061] The box cover 21 defines a suction channel 211, and the suction channel 211 is connected to the accommodating chamber 11. In this way, when the cleaning device is working, a suction device on the body, such as a suction motor, can suck the accommodating chamber 11 through the suction channel 211, so that the accommodating chamber 11 is in a negative pressure state, so as to facilitate the suction of sewage and dirt on the surface to be cleaned from the cleaning component into the sewage tank 100.

[0062] The box cover 21 can also define an activity space 212, and the in-place trigger device 22 can be movably arranged at the activity space 212. The activity space 212 can accommodate the in-place trigger device 22, and the in-place trigger device 22 can move in the form of at least one of translation and rotation. The filter component 5 is arranged in the suction channel 211. The filter component 5 can prevent the sewage droplets and dirt in the sewage tank 100 from reaching the suction device through the suction channel 211, causing damage to the suction device. In addition, the filter component 5 and the box cover 21 are detachably matched, so that after the filter component 5 has worked for a period of time, the filter component 5 can be disassembled for cleaning or replacement.

[0063] When the filter assembly 5 is installed in the suction channel 211, the filter assembly 5 abuts against the in-place trigger device 22 and drives the in-place trigger device 22 to retract into the activity space 212. At this time, the sewage tank 100 can be normally installed in the fuselage. When the filter assembly 5 is separated from the suction channel 211, the in-place trigger device 22 extends from the activity space 212 and prevents the sewage tank 100 from being installed in the fuselage. It can be understood that the opening of the activity space 212 can be set at any position of the surface of the box cover 21 for matching with the fuselage, so that when the in-place trigger device 22 extends from the activity space 212, it can exceed the matching surface of the box cover 21 and the fuselage, so that the sewage tank 100 cannot be installed back to the target position on the fuselage when the filter assembly 5 is installed in place, so as to achieve the purpose of reminding the user to install the filter assembly 5 back to the box cover 21.

[0064] According to the sewage tank 100 of the embodiment of the utility model, the in-place trigger device 22 is movably arranged at the activity space 212. When the user removes the filter assembly 5 from the box cover 21 for cleaning, replacement, or performs any other operation that causes the filter assembly 5 to be separated from the box cover 21, and when the filter assembly 5 is not reinstalled on the box cover 21, that is, the sewage tank 100 is installed back to the machine body, the in-place trigger device 22 can extend from the activity space 212 and prevent the sewage tank 100 from being installed on the machine body, thereby reminding the user that the filter assembly 5 is not installed on the box cover 21. In this way, it can be avoided that when the cleaning device is running without the filter assembly 5, the sewage tank 100 cannot suck up water and the suction device is damaged by water, thereby improving the reliability of the cleaning device and helping to improve the user experience.

[0065] In some embodiments, in combination Figure 2 and Figure 3 The activity space 212 extends vertically. Here, the top wall of the activity space 212 box cover 21 has an opening connected to the activity space 212. The in-place trigger device 22 performs telescopic movement through the opening, that is, the in-place trigger device 22 can perform telescopic movement vertically. In this way, the movement form of the in-place trigger device 22 is relatively simple and easy to implement.

[0066] In some other alternative embodiments, the activity space 212 may extend approximately horizontally on the box cover 21 so that the in-position trigger device 22 moves approximately in the horizontal direction. In this case, the opening may be provided on the side wall of the box cover 21 .

[0067] In some embodiments, in combination Figure 2 and Figure 3 The box cover 21 has a mounting platform 214 located on the side of the suction channel 211. For example, taking the sewage tank 100 as a vertical perspective, the mounting platform 214 can be formed by the top wall of the box cover 21 being recessed downward, and the suction channel 211 can pass through the bottom wall of the mounting platform 214, and at least part of the structure of the suction channel 211 extends toward the accommodating cavity 11 of the box body 1. At least part of the structure of the filter assembly 5 is embedded in the mounting platform 214, and the opening of the activity space 212 is provided in the mounting platform 214, for example, the opening of the activity space 212 is provided in the bottom wall of the mounting platform 214, and is spaced from the suction channel 211.

[0068] In this way, when the filter assembly 5 is embedded in the installation sink 214, it can be installed in the suction channel 211 at the same time, and can also directly cooperate with the in-place trigger device 22, for example, covering the upper side of the in-place trigger device 22. The overall structure is relatively simple, eliminating the need to set an intermediate transmission structure between the filter assembly 5 and the in-place trigger device 22 when the suction channel 211 and the activity space 212 are far apart, which makes the overall structure complicated; in addition, when the filter assembly 5 is installed in place, the in-place detection device can be hidden inside the box cover 21, improving the appearance consistency and making the appearance more beautiful.

[0069] In some embodiments, in combination Figure 2 and Figure 3 , the box cover 21 may be provided with a handle 213, and the handle 213 is located on the side of the sewage tank 100 facing away from the fuselage. For example, the sewage tank 100 is provided at the accommodation space on the side of the fuselage. In this case, the handle 213 is located on the side of the sewage tank 100 and on the side of the box cover 21 away from the fuselage. The activity space 212 and the in-place trigger device 22 are both located on the side of the suction channel 211 facing the handle 213. Since the position close to the handle 213 is usually the last part of the sewage tank 100 to enter the accommodation space of the fuselage when the sewage tank 100 is installed on the fuselage, the in-place trigger device 22 is arranged at a position close to the handle 213, which can reduce the collision between the in-place trigger device 22 and the fuselage, and also prevent the in-place trigger device 22 from being stuck in the recessed part on the fuselage that is provided for cooperating with the sewage tank 100 or for realizing other functions, resulting in the in-place trigger device 22. Function failure.

[0070] In some embodiments, in combination Figure 2 and Figure 3 The in-place trigger device 22 may further include a stopper 221 and a driving member 222. Specifically, the stopper 221 may be block-shaped or pin-shaped, and the sizes of the stopper 221 may be the same at various locations, or may be provided at multiple locations with different sizes or shapes as required. The stopper 221 may be movably provided in the activity space 212 to extend from the activity space 212 or retract into the activity space 212. The driving member 222 cooperates with the stopper 221 in transmission to drive the stopper 221 to move. For example, when the filter assembly 5 is separated from the box cover 21, the driving member 222 drives the stopper 221 to extend out of the activity space 212. In this way, the in-place trigger device 22 has a relatively simple structure and is easy to manufacture and assemble.

[0071] In some embodiments, the driving member 222 is configured to always exert a force on the stopper 221 toward the opening of the activity space 212. In this way, when the filter assembly 5 is separated from the box cover 21, the driving member 222 can automatically drive the stopper 221 to extend.

[0072] In some embodiments, in combination Figure 2 and Figure 3 The driving member 222 includes an elastic member, for example, the driving member 222 is a spring. Thus, when the filter assembly 5 is mounted on the box cover 21, the filter assembly 5 drives the stopper 221 to retract into the activity space 212, the stopper 221 compresses the driving member 222, and the driving member 222 stores energy. When the filter assembly 5 is removed from the box cover 21, the driving member 222 drives the stopper 221 to extend out of the activity space 212. In addition, the driving member 222 has a low cost and a long service life.

[0073] In some embodiments, in combination Figure 2 and Figure 3 The box cover 21 is provided with a limiting structure 215, and when the stopper 221 extends from the activity space 212, the limiting structure 215 cooperates with the stopper 221. In this way, the stopper 221 can be prevented from being separated from the activity space 212 when moving in the activity space 212, thereby ensuring the reliability of the in-position trigger device 22.

[0074] In some embodiments, in combination Figure 3 The stopper 221 may include: a first section 2211 and a second section 2212. The first section 2211 and the second section 2212 are sequentially arranged and connected along the moving direction, and the first section 2211 is located on the side of the second section 2212 away from the driving member 222, that is, the first section 2211 is located on the upper side of the second section 2212. The size of the first section 2211 perpendicular to the moving direction of the stopper 221 is smaller than the size of the second section 2212 perpendicular to the moving direction of the stopper 221. For example, when the cross section of the stopper 221 is circular, the diameter of the first section 2211 is smaller than the diameter of the second section 2212; when the cross section of the stopper 221 is square, the length or width of the first section 2211 is smaller than the length or width of the second section 2212. The limiting structure 215 is provided at the opening of the activity space 212. When the stopper 221 extends out of the activity space 212, the limiting structure 215 abuts against the second section 2212. In this way, it can ensure that the first section 2211 can extend from the activity space 212 to prevent the sewage tank 100 from being installed on the body without installing the filter assembly 5, and the limiting structure 215 can cooperate with the second section 2212 to prevent the stopper 221 from leaving the activity space 212.

[0075] In some embodiments, in combination Figure 2 and Figure 3, the end face of the stopper 221 away from the driving member 222 is parallel to the surface where the opening of the activity space 212 is located; when the filter assembly 5 drives the stopper 221 to retract into the activity space 212, the end face of the stopper 221 away from the driving member 222 is flush with the surface where the opening of the activity space 212 is located, that is, the upper surface of the stopper 221 is flush with the bottom wall of the installation sink 214, and when the bottom wall of the installation sink 214 is inclined relative to the horizontal plane, the upper surface of the stopper 221 is an inclined surface parallel to the bottom wall of the installation sink 214. In this way, on the one hand, it can ensure that the filter assembly 5 can be stably embedded in the predetermined installation position, and on the other hand, it can ensure that the filter assembly 5 is always in contact with the stopper 221, ensuring the sensitivity of the in-place trigger device 22 when the filter assembly 5 is separated from the box cover 21.

[0076] In some embodiments, in combination Figure 4 and Figure 5 , the filter assembly 5 may include a mounting frame 51 and a filter element 52. Specifically, the mounting frame 51 may be detachably matched with the box cover 21, for example, the mounting frame 51 may be in the shape of a cylinder with both ends open, a part of the structure of the mounting frame 51 may be adapted to the mounting sink 214 on the box cover 21, so as to be embedded in the mounting sink 214, and another part may be adapted to the suction channel 211, so as to be assembled into the suction channel 211, and provide a better support for the filter element 52. Since the mounting frame 51 has a certain strength, when the filter assembly 5 is installed in the suction channel 211, the mounting frame 51 may abut against the in-place trigger device 22. The filter element 52 is arranged on the mounting frame 51 and is in the suction channel 211. The filter element 52 may be a HEPA, a filter screen, etc. In this way, the mounting frame 51 may be used in conjunction with the in-place trigger device 22 to achieve in-place detection of the filter assembly 5.

[0077] In some embodiments, in combination Figure 2 and Figure 3 The periphery of the mounting frame 51 is provided with an outwardly protruding abutting portion 511, and the abutting portion 511 abuts against the in-position trigger device 22, for example, the abutting portion 511 can abut against the top of the stopper 221. In this way, the matching mode of the mounting frame 51 and the in-position trigger device 22 is simple and reliable, and easy to manufacture and implement.

[0078] In some embodiments, in combination Figure 4 and Figure 5One of the mounting frame 51 and the box cover 21 is provided with a fixing structure 512, and the other is provided with a fixing matching structure 216. When the mounting frame 51 is mounted to the box cover 21, the fixing structure 512 matches with the fixing matching structure 216 to fix the mounting frame 51. For example, the fixing structure 512 and the fixing matching structure 216 can be snap-fitted, plug-fitted, bolted, etc. In this way, when the filter assembly 5 is mounted to the box cover 21, the installation stability of the filter assembly 5 can be ensured, and the position of the filter assembly 5 is prevented from being unstable under the reaction force of the in-place trigger device 22, thereby further improving the reliability of the filter assembly 5.

[0079] In some embodiments, reference Figure 5 A matching gap is formed between the box cover 21 and the mounting frame 51. The side wall of the mounting frame 51 is provided with a fixing protrusion, which constitutes a fixing structure 512. The inner wall of the suction channel 211 is provided with a matching protrusion, which constitutes a fixed matching structure 216. The protrusion heights of the fixing protrusion and the matching protrusion are both smaller than the width of the matching gap. When the filter assembly 5 is installed to the suction channel 211, the fixing protrusion is located on the inner side of the matching protrusion, and the fixing protrusion and the matching protrusion interfere with each other in the extension direction of the suction channel 211. In this way, when the filter assembly 5 is installed to the box cover 21, a certain pressure can be applied to the mounting frame 51 to move the fixing protrusion from the upper side of the matching protrusion to the lower side, and realize the snap-fitting of the two, thereby ensuring the installation stability of the filter assembly 5. In addition, the fixing method of the mounting frame 51 is relatively simple, and it is easy to manufacture and assemble.

[0080] Of course, in some other embodiments, one of the fixing structure 512 and the fixing matching structure 216 may be a protrusion structure, and the other may be a groove structure. In this way, both the fixing structure 512 and the fixing matching structure 216 are relatively simple and easy to implement.
