Base structure for cleaning equipment and cleaning equipment

Abstract

The present invention relates to a base structure for cleaning equipment and a cleaning equipment. The base structure includes a base, a sterilizing light leakage prevention module, and a sterilizing module. The sterilizing light leakage prevention module includes a control switch and at least three contact members, wherein the contact ends of all the contact members are located on different straight lines to form a contact surface. When the contact ends of all the contact members are placed on the surface to be cleaned, all the control switches are in an open state to turn on the sterilizing module. When the contact end of at least one of the contact members leaves the surface to be cleaned and the angle between the contact surface and the surface to be cleaned is greater than a preset angle, the control switch is in a closed state to turn off the sterilizing module. The base structure can ensure that the base does not leak the sterilizing light generated by the sterilizing module in any direction, and can also ensure the normal operation of the sterilizing module when the contact ends of the contact members are very close to the surface to be cleaned.

Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to a base structure for cleaning equipment and the cleaning equipment. Background Art

[0002] Existing cleaning equipment, especially household sweepers, often incorporates an ultraviolet germicidal lamp (UV lamp) on the underside of the sweeper's chassis to ensure that no bacteria or other harmful microorganisms remain after sweeping. Specifically, while the sweeper's roller brush sweeps the floor, the UV lamp sterilizes the area within its irradiation range with ultraviolet light, eliminating any bacteria and other harmful microorganisms present, achieving a thorough clean.

[0003] Because UV lamps sterilize using ultraviolet light, which can be very harmful to the human body, preventing UV leakage from the lamp is a key design feature of cleaning equipment equipped with a UV lamp. Prior art designs use infrared, angle switches, or gyroscopes to control the UV lamp's on / off function. However, the inventors discovered during their research that these methods struggle to provide completely reliable UV protection, potentially causing harm to humans or pets during use due to UV leakage. Summary of the Invention

[0004] Based on this, it is necessary to provide a base structure for a cleaning device and a cleaning device to address the problem that existing cleaning equipment cannot effectively prevent ultraviolet light leakage from UV lamps.

[0011] The contact members are located at the front and rear sides of the sterilization module, wherein the contact ends of two of the contact members are close to the roller brush, and the contact end of one of the contact members is close to the roller.

[0012] In one embodiment, the contact ends of the contact members distributed near the roller brush are symmetrically distributed on both side edges of the central axis of the base, and the contact ends of the contact members distributed near the roller are located on the central axis of the base.

[0013] In one embodiment, the contact member includes: a contact portion and a mounting bracket, wherein the contact portion is capable of passing between the inner and outer portions of the base and moves toward the outer portion of the base when the contact portion leaves the surface to be cleaned;

[0014] The mounting bracket includes a mounting end and a trigger end that are relatively distributed. The mounting end is connected to the contact portion. The mounting end can drive the trigger end to move as the contact portion moves until the trigger end abuts against or disengages from the contact of the control switch, thereby closing or opening the control switch.

[0015] In one embodiment, the contact portion is a pulley-shaped structure and is rotatably connected to the mounting end of the mounting bracket via a second rotating shaft.

[0016] In one embodiment, the contact member further comprises: an elastic member disposed on the base;

[0017] When the contact portion leaves the surface to be cleaned, the elastic member is used to provide a force to the mounting end of the mounting bracket, so that the mounting end of the mounting bracket pushes the contact portion to move toward the outside of the base.

[0018] In one embodiment, a first mounting portion is provided on the mounting end of the mounting bracket, a second mounting portion is provided in the base, the first end of the elastic member is mounted on the first mounting portion, and the second end of the elastic member is mounted on the second mounting portion, wherein the first end and the second end of the elastic member are relatively distributed.

[0019] In one embodiment, a limiting bracket is provided in the base, and the limiting bracket is used to limit the deformation of the elastic member when the contact portion is placed on the surface to be cleaned.

[0020] In one embodiment, the limiting bracket is distributed close to the triggering end of the mounting bracket and can abut against the triggering end of the mounting bracket to prevent the mounting bracket from continuing to move.

[0021] In one embodiment, the mounting bracket is rotatably disposed in the base via a first rotating shaft.

[0022] In one embodiment, the mounting end and the triggering end of the mounting bracket are located on two sides of the first rotating shaft.

[0023] In one embodiment, the trigger end of the mounting bracket is located between the bottom cover of the base and the contact of the control switch;

[0025] In one embodiment, the mounting bracket is capable of linear motion to drive the contact portion to move linearly between the inner and outer portions of the base.

[0026] In one embodiment, the control switch is located on the side of the mounting bracket.

[0027] In one embodiment, a closed first installation cavity is provided on the base, and the first installation cavity is used to install the sterilization module;

In this way, it can be ensured that when the base is raised in any direction to the angle between the contact surface formed by the contact end of the contact part and the surface to be cleaned exceeds the preset angle, the control switch can sense that the contact end of the corresponding contact part leaves the surface to be cleaned and automatically cuts off the power circuit of the sterilization module, so that the sterilization module stops working, which can effectively prevent the sterilization light generated by the sterilization module from leaking. , which brings a real guarantee of health to the environment after cleaning; in addition, the control switch cuts off the power circuit of the sterilization module only when the angle between the contact surface formed by the contact end of the contact piece and the surface to be cleaned exceeds the preset angle. In this way, when the distance between the contact end of the contact piece and the surface to be cleaned is very small, for example, 1mm from the surface to be cleaned, the lifting distance of the contact end of the contact piece is a safe distance, and the leakage of sterilization light from the sterilization module is negligible, and the harm to the environment can be ignored. In this way, the normal operation of the sterilization module can be guaranteed, the frequent opening and closing of the sterilization module can be avoided, the service life of the sterilization module can be prolonged, and the user experience can be improved.

[0053] See Figure 1 , Figure 1 FIG2 shows a schematic diagram of a base structure for a cleaning device according to an embodiment of the present invention. The base structure for a cleaning device provided by an embodiment of the present invention includes: a base 100 and a sterilization module 300 and a sterilization light leakage prevention module 200 both of which are arranged on the base 100; Figures 2 to 7 As shown, the germicidal light leakage prevention module 200 includes: a control switch 220 and at least three contact members 210, and the contact ends of all the contact members 210 are not collinear to form a contact surface; Figure 4 and Figure 7 As shown, when the contact ends of all the contact members 210 are placed on the surface to be cleaned F, all the control switches 220 are in the open state to turn on the sterilization module 300; Figure 3 and Figure 6 As shown, when the contact end of at least one contact member 210 leaves the surface to be cleaned F and the angle between the contact surface and the surface to be cleaned F is greater than a predetermined angle, the switch corresponding to the contact member 210 is in the closed state, thereby shutting down the sterilization module 300. As an example, the control switch 220 is electrically connected in series to the power circuit of the sterilization module 300.

[0054] It should be noted that this cleaning device cleans floors and other surfaces to be cleaned (e.g., tabletops, windows). The cleaning device can be a handheld automatic sweeper, a handheld manually propelled sweeper, or a non-handheld disc-shaped automatic sweeper, depending on the specific situation. For ease of explanation, the following description uses a handheld automatic cleaning device as an example.

[0055] As an example, Figures 8 to 10As shown, in addition to the above-mentioned base structure, the handheld automatic cleaning device also includes: a body 600 rotatably connected to the base 100, a clean water tank 610, a dirty water tank 620, a handle 630 and a battery pack arranged on the body 600, and a drive module 700, a liquid extraction module 800 and a rotatable roller brush 400 arranged on the base 100. Among them, a power switch 640 is provided at the upper end of the handle 630, and a rotary contact switch 900 is provided at the rotation connection between the base 100 and the body 600. When the power switch 640 is turned on, the body 600 rotates relative to the base 100 toward the user. Figure 8 The initial state shown to Figure 9 In the illustrated usage state, the rotary switch 900 is turned on. Simultaneously, under the control of the rotary switch 900, the driving module 700, the liquid pumping module 800, and the sterilizing module 300 all begin to operate. Specifically, the liquid pumping module 800 can spray the cleaning liquid in the clean water tank 610 onto the surface of the roller brush 400. The roller brush 400, sprayed with the cleaning liquid, can automatically roll under the drive of the driving module 700 to automatically clean the surface F to be cleaned. The body 600 can generate suction to draw the scrubbed dirt into the dirty water tank 620. Simultaneously, the sterilizing module 300 can also sterilize and disinfect the current cleaning area. In this way, the cleaning device can not only clean visible dirt on the surface F to be cleaned, but also sterilize and disinfect invisible harmful bacteria and viruses on the current surface F to be cleaned and the surrounding area to be cleaned within a certain range. It should be noted that the power circuit of the sterilization module 300 refers to the power circuit between the sterilization module 300 and the battery pack, and the power switch 640 and the rotary contact switch 900 are both electrically connected to the power circuit in series.

[0056] Optionally, the driving module 700 may be a motor, and the pumping module 800 may be a water pump. Figure 1 and Figures 8 to 10 As shown, the rear end of the base 100 is provided with rollers 500 to facilitate the movement of the cleaning device on the surface to be cleaned F. The rollers 500 are provided at the connection between the body 600 and the base 100. Preferably, the number of the rollers 500 is two, and the two rollers 500 are symmetrically arranged relative to the central axis of the body 600, thereby ensuring the smooth movement of the entire cleaning device.

[0057] As an example, the sterilization module 300 may be sterilized by ultraviolet rays. The specific structure of the sterilization module 300 is described below and will not be described here.

[0058] As an example, Figures 2 to 10 As shown, the base 100 includes a base body 130, a bottom cover 140 covering the bottom of the base body 130, and a top cover 150 covering the top of the base body 130. Figure 3As shown, the base body 130 has a second mounting cavity 110b, and the control switch 220 is installed in the second mounting cavity 110b; the bottom cover 140 and / or the bottom plate of the base body 130 are provided with an avoidance hole 110c that communicates with the second mounting cavity 110b, and the contact end of the contact member 210 can extend from the avoidance hole 110c to the outside of the base 100.

[0059] The base structure for cleaning equipment as described above, the sterilization light leakage prevention module 200 includes a control switch 220 and at least three contact members 210, and the contact ends of all the contact members 210 are not collinear to form a contact surface and the control switch 220 is electrically connected in series to the power circuit of the sterilization module 300. In this way, it can be ensured that when the base 100 is raised in any direction to the angle between the contact surface formed by the contact end of the contact member 210 and the surface to be cleaned F exceeds the preset angle, each control switch 220 can sense that the contact end of the corresponding contact member 210 leaves the surface to be cleaned F and automatically cuts off the power circuit of the sterilization module 300, so that the sterilization module 300 stops working, which can effectively avoid the sterilization generated by the sterilization module 300. The light leaks, which brings a real guarantee of health to the environment after cleaning. In addition, the control switch 220 cuts off the power circuit of the sterilization module 300 only when the angle between the contact surface formed by the contact end of the contact member 210 and the surface to be cleaned F exceeds the preset angle. In this way, when the distance between the contact end of the contact member 210 and the surface to be cleaned F is very small, for example, 1 mm from the surface to be cleaned, the lifting distance of the contact end of the contact member 210 is a safe distance, and the leakage of sterilization light from the sterilization module 300 is negligible, and the harm to the environment can be ignored. In this way, the normal operation of the sterilization module 300 can be guaranteed, the frequent opening and closing of the sterilization module 300 can be avoided, the service life of the sterilization module 300 can be increased, and the user experience can be improved.

[0060] In some embodiments of the present invention, there are multiple control switches 220, and each control switch 220 corresponds to each contact member 210. As an example, the number of control switches 220 is the same as the number of contacts 210, that is, one contact member 210 controls the opening and closing of one control switch 220. It should be noted that the sterilization module 300 can only be turned on when all control switches 220 are in the open state. In this way, when the contact end of the contact member 210 is raised beyond a safe distance, the control switch 220 can promptly turn off the sterilization module 300, effectively preventing the leakage of the sterilization light from the sterilization module 300.

[0061] Of course, in other embodiments of the present invention, the number of control switches 220 can also be one, which can reduce the number of control switches 220 installed and reduce the cost of the base structure. As an example, the control switch 220 can include a switch body, contacts disposed on the switch body, and a trigger bracket rotatably disposed within the base 100. The trigger bracket has a structure similar to a seesaw. When the contact ends of all contact members 210 are placed on the surface to be cleaned F, the trigger bracket abuts against the contacts on the switch body to close or open the control switch 220. When the contact end of at least one contact member 210 is raised above the surface to be cleaned F and exceeds a safe distance, the trigger bracket disengages from the contacts on the switch body to close or open the control switch 220.

[0062] In some embodiments of the present invention, Figure 1 、 Figure 2 、 Figure 5 and Figure 11 As shown, there are three contacts 210. Three points can define a plane, minimizing the number of contacts 210 and reducing production costs. Of course, in other embodiments of the present invention, the number of contacts 210 can be greater than three, such as four or five. When there are four contacts 210, the contact ends of these four contacts 210 can be distributed at the four corners of the base 100.

[0063] Furthermore, in some embodiments of the present invention, Figure 1 As shown, the base structure also includes a roller brush 400 and a roller 500, which are rotatably disposed at the front and rear ends of the base 100, respectively. Contact members 210 are located at the front and rear ends of the sterilization module 300, with the contact ends of two contact members 210 located near the roller brush 400 and the contact end of one contact member 210 located near the roller 500. This distribution of the contact members 210 ensures that the contact surfaces formed by the contact ends of the contact members 210 fully cover the bottom surface of the base 100.

[0064] Specifically in some embodiments of the present invention, such as Figure 1 As shown, the contact ends of the contact members 210 near the roller brush 400 are symmetrically distributed on both sides of the central axis of the base 100, while the contact ends of the contact members 210 near the roller 500 are located on the central axis of the base 100. This effectively ensures that all areas on the bottom of the base 100 can effectively prevent the leakage of sterilizing light.

[0065] In some embodiments of the present invention, Figures 2 to 7As shown, the contact member 210 includes a contact portion 211 and a mounting bracket 212. The contact portion 211 can pass between the interior and exterior of the base 100 and move toward the exterior of the base 100 when the contact portion 211 leaves the surface to be cleaned F. The mounting bracket 212 includes a mounting end 2121 and a trigger end 2122 that are relatively distributed. The mounting end 2121 is connected to the contact portion 211. The mounting end 2121 can drive the trigger end 2122 to move as the contact portion 211 moves, until the trigger end 2122 abuts or disengages from the contact of the control switch 220, thereby closing or opening the control switch 220. It will be understood that the contact portion 211 constitutes the contact end of the contact member 210. In implementation, the preset angle can be set by adjusting the positional relationship between the control switch 220 and the trigger end 2122 of the mounting bracket 212. As an example, when the number of the control switch 220 is one, the trigger end 2122 of the mounting bracket 212 is used to abut against the trigger bracket of the control switch 220 to close or open the control switch 220 .

[0066] It should be noted that when the contact of the control switch 220 is pressed, it can be adjusted from the closed state to the open state, or from the open state to the closed state. Figure 4 and Figure 7 As shown, when the contact portion 211 of the contact member 210 is placed on the surface to be cleaned F, the surface to be cleaned F will press the contact portion 211 back, and the contact portion 211 moves toward the interior of the base 100 and simultaneously drives the mounting end 2121 of the mounting bracket 212 to move. The trigger end 2122 of the mounting bracket 212 then moves along with the mounting end 2121 until it is disengaged from the contact point of the control switch 220, thereby turning on the control switch 220; Figure 3 and Figure 6 As shown, when the contact portion 211 of the contact member 210 is raised and exceeds the safety distance, the contact portion 211 of the contact member 210 moves toward the outside of the base 100 and simultaneously drives the mounting end 2121 of the mounting bracket 212 to move. The trigger end 2122 of the mounting bracket 212 then moves along with the mounting end 2121 until it abuts against the contact of the control switch 220, thereby turning off the control switch 220. For another example, when the contact portion 211 of the contact member 210 is placed on the surface to be cleaned F, the trigger end 2122 of the mounting bracket 212 may also abut against the contact of the control switch 220, thereby turning on the control switch 220. Then, when the contact portion 211 of the contact member 210 is raised and exceeds the safety distance, the trigger end 2122 of the mounting bracket 212 moves along with the mounting end 2121 until it disengages from the contact of the control switch 220, thereby turning off the control switch 220.

[0067] Alternatively, as Figure 1As shown, the contact portion 211 is a pulley-shaped structure and is rotatably connected to the mounting end 2121 of the mounting bracket 212 via a second rotating shaft 2111. The pulley-shaped contact portion 211 can reduce the friction between the contact portion 211 and the surface to be cleaned F, thereby ensuring smooth movement of the cleaning device.

[0068] Further, if Figures 2 to 7 As shown, in some embodiments of the present invention, the contact member 210 further includes an elastic member 213 disposed on the base 100. When the contact portion 211 leaves the surface to be cleaned F, the elastic member 213 is configured to apply force to the mounting end 2121 of the mounting bracket 212, so that the mounting end 2121 of the mounting bracket 212 pushes the contact portion 211 toward the outside of the base 100. This facilitates the contact portion 211 to move toward the outside of the base 100 when leaving the surface to be cleaned F, thereby smoothly closing the control switch 220.

[0069] Optionally, the elastic member 213 is a spring. The spring can be Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The compression spring shown is installed between the base 130 and the mounting end 2121 of the mounting bracket 212. When the contact portion 211 is placed on the surface to be cleaned F, the spring is in a compressed state. When the contact portion 211 leaves the surface to be cleaned F, the spring returns to the outside of the base 100. Of course, in other embodiments of the present invention, the spring may be a tension spring and installed between the bottom cover 140 and the mounting end 2121 of the mounting bracket 212. When the contact portion 211 is placed on the surface to be cleaned F, the spring is in a tensioned state. When the contact portion 211 leaves the surface to be cleaned F, the spring returns to the outside of the base 100.

[0070] Alternatively, as Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, a first mounting portion 2123 is provided on the mounting end 2121 of the mounting bracket 212, and a second mounting portion 110 is provided in the base 100. The first end of the elastic member 213 is mounted on the first mounting portion 2123, and the second end of the elastic member 213 is mounted on the second mounting portion 110, wherein the first end and the second end of the elastic member 213 are relatively distributed. The first mounting portion 2123 can cooperate with the second mounting portion 110 to limit the elastic member 213, and can effectively provide a force to the mounting end 2121 of the mounting bracket 212, so that the contact portion 211 moves toward the outside of the base 100. Optionally, the first mounting portion 2123 is a raised structure or Figure 3 、 Figure 4 、 Figure 6 and Figure 7 In the groove structure shown, the second mounting portion 110 is Figure 3 、 Figure 4 The raised structure shown or Figure 6 、 Figure 7 The corresponding end of the elastic member 213 is located in the groove structure, and the corresponding end is sleeved on the protrusion structure in an interference fit manner.

[0071] Alternatively, as Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, a limiting bracket 120 is provided within the base 100. The limiting bracket 120 is used to limit the deformation of the elastic member 213 when the contact portion 211 is placed on the surface to be cleaned F. The limiting bracket 120 is used to prevent the elastic member 213 from deforming too much when the contact portion 211 is placed on the surface to be cleaned F. In other words, it limits the elastic action space of the elastic member 213 to prevent excessive force between the contact portion 211 and the surface to be cleaned F due to excessive deformation of the elastic member 213 when the contact portion 211 leaves the surface to be cleaned F. The limiting bracket 120 is located near the trigger end 2122 of the mounting bracket 212 and can abut against the trigger end 2122 of the mounting bracket 212 to prevent the mounting bracket 212 from continuing to move. This facilitates the installation of the limiting bracket 120. Of course, in some other embodiments of the present invention, the limiting bracket 120 may also be distributed close to the mounting end 2121 of the mounting bracket 212 and be able to abut against the mounting end 2121 of the mounting bracket 212 .

[0072] Regarding the installation method of the mounting bracket 212 in the base 100, two examples are given:

[0073] The first example, such as Figures 2 to 4 As shown, the mounting bracket 212 is rotatably disposed in the base 100 via the first rotating shaft 2124. Furthermore, the mounting end 2121 and the trigger end 2122 of the mounting bracket 212 are located on both sides of the first rotating shaft 2124. This can reduce the overall thickness of the base 100. Furthermore, as Figure 3 and Figure 4 As shown, the trigger end 2122 of the mounting bracket 212 is located between the bottom cover 140 of the base 100 and the contact of the control switch 220. When the control switch 220 is in the off state, the trigger end 2122 of the mounting bracket 212 abuts the contact of the control switch 220. When the control switch 220 is in the on state, the trigger end 2122 of the mounting bracket 212 separates from the contact of the control switch 220. This allows the mounting bracket 212 to be closer to the avoidance hole 110c, reducing the size of the contact portion 211. Optionally, the elastic member 213, the contact portion 211, and the mounting end 2121 of the mounting bracket 212 are coaxially arranged to improve the sensitivity of the control switch 220.

[0074] The second example, such as Figures 5 to 7 As shown, the mounting bracket 212 can move linearly to drive the contact portion (211) to move linearly between the inner and outer parts of the base 100. The mounting bracket 212 of this type of structure is simple in structure. Optionally, the control switch 220 is located on the side of the mounting bracket 212. In this way, the thickness of the base 100 can be reduced. Optionally, a step structure is formed between the mounting end 2121 and the trigger end 2122 of the mounting bracket 212, and the step structure is used to limit the range of movement of the contact end to within the second mounting cavity 110b.

[0075] In some embodiments of the present invention, Figure 11 As shown, the base 100 is provided with a closed first mounting cavity 110a for mounting the sterilization module 300. The base 100 is also provided with a light-transmitting window communicating with the first mounting cavity 110a to ensure that the sterilization light emitted by the sterilization module 300 does not pass through other parts of the base body 130.

[0076] In some embodiments of the present invention, Figure 11 As shown, the base 100 is provided with a first mounting cavity 110a; Figure 11 and Figure 12 As shown, the sterilization module 300 includes: an ultraviolet germicidal lamp 310 arranged in the first installation cavity 110a and a translucent cover 320 arranged at the cavity opening of the first installation cavity 110a. The power of the ultraviolet germicidal lamp 310 is greater than or equal to the preset power. Through the cooperation of the high-power ultraviolet germicidal lamp 310 and the translucent cover 320, it can be ensured that the sterilization and disinfection can be more thorough during the cleaning process, and even achieve the effect of killing bacteria instantly, which is conducive to further providing a real health guarantee for the cleaned environment. Among them, the translucent cover 320 can not only reduce the loss of ultraviolet light, but also further ensure the airtightness of the first installation cavity 110a, and play a protective role for the ultraviolet germicidal lamp 310. Optionally, the preset power is 18w.

[0077] Further, if Figure 11 and Figure 12 As shown, the sterilization module 300 also includes a reflective housing 330, a lamp holder 340, and a pressure cover 350. The reflective housing 330 is disposed within the first mounting cavity 110a. One end of the ultraviolet germicidal lamp 310 is mounted on the base 130 via the lamp holder 340. The lamp body of the ultraviolet germicidal lamp 310 is partially accommodated within the accommodating cavity formed by the reflective housing 330. This allows the germicidal light emitted by the ultraviolet germicidal lamp 310 to be scattered on the reflective housing 330, ensuring a more uniform germicidal light emitted from the translucent cover 320, thereby achieving a better sterilization effect. As an example, a connector 360 is disposed within the first mounting cavity 110a, with the lamp holder 340 of the ultraviolet germicidal lamp 310 electrically connected to the connector 360.

[0078] Another embodiment of the present invention provides a cleaning device, such as Figures 8 to 10 As shown, the cleaning device includes the base structure described in any one of the above items.

[0079] The base structure for cleaning equipment as described above, the sterilizing light leakage prevention module 200 includes a control switch 220 and at least three contact members 210, and the contact ends of all the contact members 210 are located on different straight lines to form a contact surface and all the control switches 220 are electrically connected in series to the power circuit of the sterilizing module 300. In this way, it can be ensured that when the base 100 is raised in any direction to the angle between the contact surface formed by the contact end of the contact member 210 and the surface to be cleaned F exceeds the preset angle, the control switch 220 can sense that the contact end of the corresponding contact member 210 leaves the surface to be cleaned F and automatically cuts off the power circuit of the sterilizing module 300, so that the sterilizing module 300 stops working, which can effectively avoid the sterilizing module 300 from generating The sterilization light does not leak, which brings a truly healthy guarantee to the environment after cleaning; in addition, the control switch 220 cuts off the power circuit of the sterilization module 300 only when the angle between the contact surface formed by the contact end of the contact member 210 and the surface to be cleaned F exceeds a preset angle. In this way, when the contact end of the contact member 210 is very close to the surface to be cleaned F, for example, 1 mm away from the surface to be cleaned, the lifting distance of the contact end of the contact member 210 is a safe distance, the leakage of the sterilization light of the sterilization module 300 is negligible, and the harm to the environment can be ignored. In this way, the normal operation of the sterilization module 300 can be guaranteed, the frequent opening and closing of the sterilization module 300 can be avoided, the service life of the sterilization module 300 can be increased, and the user experience can be improved.

[0080] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
