Description

Technical Field

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

[0002] In existing cleaning devices, especially household floor sweepers, in order to ensure that no harmful microorganisms such as bacteria remain on the ground after cleaning, an ultraviolet germicidal lamp (hereinafter referred to as a UV lamp) is usually installed at the bottom of the base of the floor sweeper. Specifically, while the rotary brush on the base of the floor sweeper sweeps the ground, the UV lamp irradiates the ground within the irradiation range with ultraviolet light for germicidal purposes, thereby removing harmful microorganisms such as bacteria on the current ground and achieving the purpose of thoroughly cleaning the ground.

[0003] Since the UV lamp sterilizes by ultraviolet rays, and ultraviolet rays can cause great harm to the human body when irradiated on the human body, therefore, the technology for preventing ultraviolet ray leakage of such cleaning devices with UV lamps will become a key technology in the design. In the prior art, there are related designs that use infrared, angle switches, or gyroscopes to control the on / off of the UV lamp. However, the inventor found during actual research that these are all difficult to achieve completely reliable ultraviolet protection, that is, during use, it is still possible for ultraviolet rays to leak and cause harm to the human body or pets. Summary of the Invention

[0004] Based on this, in view of the problem that ultraviolet rays may still leak during the use of the above-mentioned cleaning device and cause harm to the human body or pets, it is necessary to provide a base structure for a cleaning device and a cleaning device.

[0005] A base structure for a cleaning device includes: a base, a protection module, and a sterilization module disposed on the base.

[0006] The protection module includes a light-shielding member and at least one control switch. The light-shielding member is disposed on the base and can move in a direction away from or close to the surface to be cleaned. The light-shielding member surrounds the periphery of the sterilization module.

[0007] When the light-shielding member is placed on the surface to be cleaned, the control switch can turn on the sterilization module, and the light-shielding member can block the sterilization light from leaking to the outside of the base structure. When at least a part of the light-shielding member leaves the surface to be cleaned and moves in a direction close to the surface to be cleaned, the control switch can turn off the sterilization module. In one embodiment, a contact portion corresponding to the contact of the control switch is provided on the base.

[0008] The light-shielding member is connected to the control switch, and when at least a part of the light-shielding member leaves the surface to be cleaned and moves in a direction close to the surface to be cleaned, it can drive the corresponding control switch to move until the contact of the corresponding control switch abuts against or separates from the corresponding contact portion, so as to turn off the sterilization module.

[0009] In one embodiment, a first non-contact sensor is further provided on the base, and a second non-contact sensor corresponding to the first non-contact sensor is further provided on the light-shielding member;

[0010] When the distance between the first non-contact sensor and the second non-contact sensor is greater than a preset distance, the control switch can turn off the sterilization module.

[0011] In one embodiment, the protection module further includes at least one elastic member, and the elastic member is connected to the base and the light-shielding member;

[0012] When at least a part of the light-shielding member leaves the surface to be cleaned, the elastic member is used to provide a force for the light-shielding member to move towards the surface to be cleaned.

[0013] In one embodiment, the contact portion of the base is provided on the lower cover of the base and has a receiving groove, and one end of the elastic member is installed in the receiving groove.

[0014] In one embodiment, the light-shielding member includes: a first light-shielding plate, a second light-shielding plate and a third light-shielding plate connected in sequence. The second light-shielding plate is distributed near the rear end of the base and extends along the width direction of the base, and the first light-shielding plate and the third light-shielding plate extend along the length direction of the base.

[0015] In one embodiment, a deformable protective strip is provided at the lower end of the second light-shielding plate. The protective strip is in the same extension direction as the second light-shielding plate, and the lower surface of the protective strip is flush with the lower surfaces of the first light-shielding plate and the third light-shielding plate.

[0016] In one embodiment, the number of the control switches is 4. Two of the control switches are respectively arranged in the middle of the first light-shielding plate and the third light-shielding plate, and two of the control switches are respectively arranged at the left and right ends of the second light-shielding plate.

[0017] In one embodiment, the protection module further includes at least one rolling member, and the rolling member is rotatably arranged on the light-shielding member.

[0018] In one embodiment, the number of the rolling members is 4, and the 4 rolling members are respectively arranged at the left and right ends of the light-shielding member and are symmetrical about the center axis of the base.

[0019] In one embodiment, the sterilization module includes: an ultraviolet sterilization lamp, quartz glass, and a lamp holder;

[0020] The lamp holder is disposed on the base and has an installation cavity. The ultraviolet sterilization lamp is installed in the installation cavity and has a power greater than or equal to a preset power. The quartz glass covers the opening of the installation cavity.

[0021] In one embodiment, a transverse plate is provided at the front end of the lamp holder. The transverse plate is located between the first light-shielding plate and the third light-shielding plate and forms a light-shielding cavity with the light-shielding member. The opening of the installation cavity is located in the light-shielding cavity.

[0022] In one embodiment, a mood lamp member is further provided on the base. The mood lamp member is disposed on the left and right sides of the light-shielding member.

[0023] A cleaning device, the cleaning device including the base structure according to any one of the above.

[0024] In one embodiment, the cleaning device further includes: an upright handle, a vacuum suction source, a garbage channel, a roller brush housing, a roller brush scraper, a sewage tank, a clean water tank, and a fluid dispenser;

[0025] The upright handle is operably connected to the base of the base structure. The roller brush is installed on the base. The vacuum suction source and the clean water tank are disposed on the upright handle. The sewage tank is disposed on the upright handle or the base. The vacuum suction source is used to generate suction to suck fluid or garbage from the ground through the garbage channel into the sewage tank. The roller brush housing is disposed on the base and at least partially surrounds the roller brush. The roller brush housing and the roller brush cooperate to form a suction nozzle. The suction nozzle is communicated with the sewage tank through the garbage channel, so that the fluid or garbage on the ground enters the garbage channel through the suction nozzle;

[0026] The fluid dispenser is disposed on the upright handle or the base. The fluid dispenser is communicated with the clean water tank through a fluid transmission path and is used to apply the fluid in the clean water tank to the roller brush or the surface to be cleaned;

[0027] The roller brush scraper is formed on the roller brush housing or the base. The roller brush scraper is used to scrape off the dust or liquid remaining on the roller brush.

[0028] The base structure for a cleaning device and the cleaning device described above, when the light-shielding member of the base structure is placed on the surface to be cleaned, the control switch turns on the sterilization module. Then, during the process of the sterilization module sterilizing the surface to be cleaned, since the light-shielding member surrounds the sterilization module on all sides, it can cooperate with the surface to be cleaned to place the sterilization module in a relatively enclosed space. In this way, even when the light-shielding member does not leave the surface to be cleaned, it can effectively prevent the sterilization light of the sterilization module from leaking to the outside of the base structure. Additionally, once at least a part of the light-shielding member leaves the surface to be cleaned and moves in a direction close to the surface to be cleaned, the working state of the control switch is adjusted from the on state to the off state, thereby turning off the sterilization module and preventing the sterilization light generated by the sterilization module from leaking through the gap between the light-shielding member and the surface to be cleaned, providing a truly healthy guarantee for the cleaned environment.

The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0045] An embodiment of the present invention provides a base structure 10 for a cleaning device, as Figures 1 to 6 shown. The base structure 10 includes: a base 100, a protection module 300, and a sterilization module 200 disposed on the base 100; the protection module 300 includes a light-shielding member 310 and at least one control switch 320. The light-shielding member 310 is disposed on the base 100 and can move in a direction away from or close to the surface to be cleaned. The light-shielding portion of the light-shielding member 310 is located outside the base 100 and surrounds the periphery of the sterilization module 200. When the light-shielding member 310 is placed on the surface to be cleaned, the control switch 320 can turn on the sterilization module 200, and the light-shielding member 310 can block the sterilization light from leaking out of the base structure 10 to the outside. When at least a part of the light-shielding member 310 leaves the surface to be cleaned and moves in a direction close to the surface to be cleaned, the contact 321 of the corresponding control switch 320 can turn off the sterilization module 200.

[0046] It should be noted that this cleaning device is used to clean the ground and other surfaces to be cleaned (such as table tops, glass windows). Among them, the cleaning device can be a handheld automatic sweeper, a handheld manually pushed sweeper, or a non-handheld disc-shaped automatic sweeper, etc., which can be determined according to the actual situation. For the convenience of description, the following takes a handheld automatic cleaning device as an example for illustration.

[0047] As an example, as Figures 4 to 5 shown, in addition to the above-mentioned base structure 10, the handheld automatic cleaning device further includes an upright handle 50 operably connected to the base 100. The upright handle 50 can be used to set the handheld part and modules such as the controller and power supply of the cleaning device. The cleaning device also has a vacuum suction source, a garbage passage, a roller brush cover 190, a roller brush scraper, a sewage tank 40, a water tank 30, a fluid dispenser, a liquid pumping module, a roller brush motor, and a roller brush 170 installed on the base 100, etc. Among them, the vacuum suction source and the water tank 30 can be selectively arranged on the upright handle 50; the sewage tank 40 can be selectively arranged on the upright handle 50 or the base 100; the roller brush cover 190 of the cleaning device is arranged on the base 100, and the roller brush cover 190 at least partially surrounds the roller brush 170; the roller brush motor is installed in the base 100. It should be noted that the upright handle 50 being operably connected to the base 100 means that the upright handle 50 is detachably and / or rotatably connected to the base 100. In addition, the upright handle 50 includes a handheld part and an installation part for installing components such as the vacuum suction source, the water tank 30, and the sewage tank 40.

[0048] Among them, a power switch 50a is arranged on the handheld part of the upright handle 50, and a rotary contact switch 180 is arranged at the rotational connection between the base 100 and the upright handle 50. After the power switch 50a is turned on, the upright handle 50 rotates from the Figure 4 initial state shown towards the user to Figure 5During the use state shown, the transfer contact switch 180 is turned on. At the same time, under the control of the transfer contact switch 180, the roller brush motor, the liquid pumping module, and the sterilization module 200 all start to work. That is, at this time, the liquid pumping module can spray the cleaning liquid in the water tank 30 onto the surface of the roller brush 170. The roller brush 170 sprayed with the cleaning liquid can automatically roll under the drive of the roller brush motor to achieve automatic cleaning of the surface to be cleaned. The vacuum suction source can generate suction to suck the dirt after brushing into the sewage tank 40. At the same time, the sterilization module 200 can also sterilize and disinfect the current cleaning area. In this way, the cleaning device can not only complete the cleaning of visible dirt on the surface to be cleaned, but also sterilize and disinfect invisible harmful bacteria and viruses in the current surface to be cleaned and the surrounding cleaning area within a certain range. It should be noted here that the energized circuit of the sterilization module 200 refers to the energized circuit between the sterilization module 200 and the battery pack, and the power switch 50a and the transfer contact switch 180 are electrically connected in series to this energized circuit.

[0049] Optionally, the liquid pumping module can be a water pump. Optionally, as Figure 1 and Figure 3 shown, front rollers 130 and rear rollers 140 are respectively arranged at the front and rear ends of the base structure 10, which facilitates the cleaning device to walk on the surface to be cleaned. Among them, the front rollers 130 are distributed close to the roller brush 170, and the rear rollers 140 are arranged at the connection between the fuselage 20 and the base 100. Preferably, the number of both the front rollers 130 and the rear rollers 140 is 2, and they are symmetrically arranged with respect to the central axis of the fuselage 20 to ensure the stable walking of the entire cleaning device. It should be noted that the "front", "rear", "left", and "right" directions involved in this article are all based on Figure 4 shown.

[0050] As an example, the sterilization module 200 can use ultraviolet rays for sterilization. Among them, the specific structure of the sterilization module 200 is described below and will not be described here.

[0051] As an example, as Figure 3 and Figure 6 shown, the base 100 includes an upper cover 150 and a lower cover 160. The roller brush motor and the liquid pumping module are arranged in the space surrounded by the upper and lower covers 160. The sterilization module 200 and the protection module 300 are arranged on the lower cover 160. The roller brush 170 is rotatably arranged on the upper cover 150 and exposed at the opening of the lower cover 160.

[0052] The base structure 10 for a cleaning device as described above. When the light-shielding member 310 is placed on the surface to be cleaned, the control switch 320 can turn on the sterilization module 200. Then, during the process of the sterilization module 200 sterilizing the surface to be cleaned, since the light-shielding member 310 surrounds the periphery of the sterilization module 200, it can cooperate with the surface to be cleaned to place the sterilization module 200 in a relatively enclosed space. In this way, even when the light-shielding member 310 does not leave the surface to be cleaned, it can effectively block the leakage of the sterilization light from the sterilization module 200 to the outside of the base structure 10. Additionally, once at least a part of the light-shielding member 310 leaves the surface to be cleaned and moves in the direction close to the surface to be cleaned, the working state of the corresponding control switch 320 is adjusted from the on state to the off state, thereby turning off the sterilization module 200 and preventing the sterilization light generated by the sterilization module 200 from leaking out through the gap between the light-shielding member 310 and the surface to be cleaned, providing a true guarantee of health for the cleaned environment.

[0053] In some embodiments of the present invention, as Figure 7 and Figure 8 shown, the light-shielding member 310 includes: a first light-shielding plate 311, a second light-shielding plate 312, and a third light-shielding plate 313 connected in sequence. The second light-shielding plate 312 is distributed near the rear end of the base 100 and extends along the width direction of the base 100. The first light-shielding plate 311 and the third light-shielding plate 313 extend along the length direction of the base 100. It should be noted that the length direction of the base 100 refers to the direction from the front side to the rear side of the base 100 or from the rear side to the front side of the base 100, and the width direction of the base 100 refers to the direction from the left side to the right side of the base 100 or from the right side to the left side of the base 100. The structure of such a light-shielding member 310 is simple and convenient for preparation and production.

[0054] Furthermore, as Figure 7 and Figure 8As shown, a protective strip 314 that can be squeezed and deformed is provided at the lower end of the second light-shielding plate 312. The protective strip 314 is in the same extending direction as the second light-shielding plate 312, and the lower surface of the protective strip 314 is flush with the lower surfaces of the first light-shielding plate 311 and the third light-shielding plate 313. It should be noted that the lower surfaces of the protective strip 314, the first light-shielding plate 311, and the third light-shielding plate 313 refer to the lower surfaces of the protective strip 314, the first light-shielding plate 311, and the third light-shielding plate 313 when the cleaning device is working properly. When encountering an obstacle, the protective strip 314 can be deformed to avoid damage to the light-shielding member 310, thus playing a protective role. Optionally, the protective strip 314 can be made of a hard plastic material (such as rubber), and the protective strip 314 can be formed on the second light-shielding plate 312 by means of bonding, integral molding (such as injection molding), etc. Optionally, the first light-shielding plate 311 and the third light-shielding plate 313 can be made of a hard plastic material, such as PP (Polypropylene, polyethylene), which can avoid excessive friction between the base structure 10 and the surface to be cleaned. The second light-shielding plate 312 can be made of the same material as the first light-shielding plate 311 and the third light-shielding plate 313.

[0055] On the premise that the light-shielding member 310 includes the first light-shielding plate 311, the second light-shielding plate 312, and the third light-shielding plate 313, specifically in some embodiments of the present invention, the number of control switches 320 is 4. Two control switches 320 are respectively arranged in the middle of the first light-shielding plate 311 and the third light-shielding plate 313, and two control switches 320 are respectively arranged at the left and right ends of the second light-shielding plate 312. By arranging the control switches 320 in this way, on the premise of ensuring a certain sensitivity of the protection module 300, the number of control switches 320 can be reduced as much as possible, thereby reducing the cost of the base structure 10. Optionally, the two control switches 320 are symmetrical about the axis of symmetry of the base 100.

[0056] In some embodiments of the present invention, as Figure 3 , Figure 7 and Figure 8 shown, the protection module 300 further includes at least one elastic member 330, and the elastic member 330 is connected to the base 100 and the light-shielding member 310; when at least a part of the light-shielding member 310 leaves the surface to be cleaned, the elastic member 330 is used to provide a force for the light-shielding member 310 to move towards the surface to be cleaned. Once the light-shielding member 310 leaves the surface to be cleaned, the light-shielding member 310 can quickly move towards the surface to be cleaned under the action of the elastic member 330, and then can quickly close the control switch 320, improving the sensitivity of the protection module 300.

[0057] It can be understood that the number and arrangement position of the elastic members 330 are the same as those of the control switches 320, that is, the elastic members 330 correspond to the control switches 320 one by one. For example, as Figure 7 and Figure 8As shown, the number of elastic members 330 is four. Two elastic members 330 are respectively distributed in the middle parts of the first light-shielding plate 311 and the third light-shielding plate 313, and two elastic members 330 are arranged at the left and right ends of the second light-shielding plate 312 and are symmetric about the central axis of the base 100.

[0058] Optionally, the elastic member 330 can be a spring or a structure capable of elastic deformation, such as a rubber ring.

[0059] Optionally, as Figure 4 shown, a receiving groove is provided on the lower cover 160 of the base 100, and one end of the elastic member 330 is installed in the receiving groove. The receiving groove can play a role in fixing the elastic member 330. As an example, when the control switch 320 is set as a mechanical control switch, the receiving groove is opened on the contact portion 110; when the light-shielding member 310 is placed on the surface to be cleaned, the contact 321 of the control switch 320 is separated from the contact portion 110 of the base 100, and when at least a part of the light-shielding member 310 leaves the surface to be cleaned, the corresponding contact 321 of the control switch 320 can abut against the contact portion 110 of the base 100. Among them, the elastic member 330 can be installed in the receiving groove of the contact portion 110 by an interference fit method. It can be understood that the number and arrangement positions of the contact portions 110 of the base 100 are the same as those of the elastic members 330, that is, the elastic members 330 and the contact portions 110 are in one-to-one correspondence. Exemplarily, the number of the contact portions 110 is four. Two contact portions 110 are respectively distributed in the middle parts of the first light-shielding plate 311 and the third light-shielding plate 313, and two contact portions 110 are distributed at the left and right ends of the second light-shielding plate 312 and are symmetric about the central axis of the base 100.

[0060] Optionally, as Figure 3 shown, the light-shielding member 310 is provided with at least one mounting post 315, and the other end of the elastic member 330 is sleeved on the corresponding mounting post 315. Through the cooperation of the contact portion 110 of the base 100 and the mounting post 315, the detachable connection between the light-shielding member 310 and the base 100 can be realized. Among them, the elastic member 330 can be sleeved on the mounting post 315 by an interference fit method. Regarding the shape of the mounting post 315, it can be a smooth rod structure or Figure 3 shown cross-shaped structure, and the embodiments of the present invention do not make specific limitations. It can be understood that the number and arrangement positions of the mounting posts 315 are the same as those of the elastic members 330, that is, the mounting posts 315 and the elastic members 330 are in one-to-one correspondence. Exemplarily, the number of the mounting posts 315 is four. Two mounting posts 315 are respectively distributed in the middle parts of the first light-shielding plate 311 and the third light-shielding plate 313, and two mounting posts 315 are distributed at the left and right ends of the second light-shielding plate 312 and are symmetric about the central axis of the base 100.

[0061] In some embodiments of the present invention, as Figure 3As shown, at least one connecting lug 323 extending towards the light-shielding member 310 is provided on the housing 322 of the control switch 320; as Figure 3 , Figure 7 and Figure 8 shown, at least one stud 316 extending towards the control switch 320 is provided on the light-shielding member 310, and the stud 316 is connected to the corresponding connecting lug 323 by a threaded member. This facilitates the replacement of the control switch 320 and the light-shielding member 310. Regarding the number and distribution position of the connecting lugs 323, the embodiments of the present invention do not make specific limitations. For example, the number of the connecting lugs 323 is 2, and the 2 connecting lugs 323 are symmetrically distributed on both sides of the contact 321 of the control switch 320. In this way, the light-shielding member 310 and the control switch 320 can be effectively and firmly connected. In addition, the number and distribution position of the studs 316 are not only related to the connecting lugs 323, but also related to the number and distribution position of the control switches 320. By way of example, as Figure 6 and Figure 7 shown, the number of the studs 316 is 8, 2 studs 316 are distributed in the middle of the first light-shielding plate 311, 2 studs 316 are distributed in the middle of the third light-shielding plate 313, and 4 studs 316 are symmetrically distributed about the axis of symmetry of the base 100 at the left and right ends of the second light-shielding plate 312.

[0062] In some embodiments of the present invention, as Figure 3 , Figure 7 and Figure 8 shown, the protection module 300 further includes at least one rolling member 340, and the rolling member 340 is rotatably provided on the light-shielding member 310. As an example, the lower surface of the rolling member 340 is flush with the lower surface of the light-shielding member 310. The rolling member 340 can reduce the friction between the light-shielding member 310 and the surface to be cleaned, which is beneficial to the movement of the cleaning device. It can be understood that, as Figure 8 shown, the rolling member 340 is installed on the light-shielding member 310 through a rotating shaft 341.

[0063] Optionally, the rolling member 340 can be a roller. In addition, as Figure 7 and Figure 8 shown, the number of the rolling members 340 is 4, and the 4 rolling members 340 are symmetrically arranged about the axis of symmetry of the base 100 at the left and right ends of the light-shielding member 310. In this way, the movement of the cleaning device is made more stable. As an example, 2 rolling members 340 are respectively arranged at the front ends of the first light-shielding plate 311 and the third light-shielding plate 313 of the light-shielding member 310, and 2 rolling members 340 are respectively arranged at the joints between the first light-shielding plate 311 and the second light-shielding plate 312 and between the third light-shielding plate 313 and the second light-shielding plate 312 of the light-shielding member 310.

[0064] The following (3) methods are given for how the control switch 320 opens and closes the sterilization module 200:

[0065] The first method: In some embodiments of the present invention, a first non-contact sensor is further provided on the base 100, and a second non-contact sensor corresponding to the operation of the first non-contact sensor is further provided on the light-shielding member 310; the distance between the first non-contact sensor and the second non-contact sensor is detected by a signal. It should be noted that the first non-contact sensor and the second non-contact sensor can also be in the form of electromagnetic sensors to detect the change in magnetic flux to achieve the braking of the control switch. The first non-contact sensor, the second non-contact sensor, and the control switch perform corresponding actions through a control system. The first non-contact sensor and the second non-contact sensor communicate with the control system and send the measured distance values to the control system, and the control system determines whether the distance between the first non-contact sensor and the second non-contact sensor exceeds the system preset threshold. Specifically, the control system can control the control switch 320 to close the sterilization module 200 when the distance between the first non-contact sensor and the second non-contact sensor is greater than the preset distance S0 to prevent the leakage of ultraviolet light. When the distance between the first non-contact sensor and the second non-contact sensor is less than or equal to the preset distance S0, the control switch 320 does not perform the action of closing the sterilization module 200. Since a spring or an elastic floating member is provided between the base 100 and the light-shielding member 310, the distance between the base 100 and the light-shielding member will also change according to the deformation of the spring. When the machine is placed on the ground, due to the restraint of the ground, the distance between the first non-contact sensor and the second non-contact sensor will not exceed the distance threshold set by the system. When the machine is partially or completely lifted off the ground, when the distance between the base 100 and the light-shielding member 310 increases to the system-set distance threshold S0 under the action of the spring, the control system can control the control switch 320 to close the sterilization module. When the preset distance S0 between the base and the light-shielding member when the machine is on the ground is exceeded, in order to prevent the leakage of sterilization light, the control switch selectively closes the sterilization module.

[0066] The second method: In some embodiments of the present invention, as Figure 3As shown in the figure, a contact portion 110 corresponding to the contact 321 of the control switch 320 is provided on the base 100; the light-shielding member 310 is connected to the control switch 320, and when at least a part of the light-shielding member 310 leaves the surface to be cleaned and moves in a direction close to the surface to be cleaned, it can drive the corresponding control switch 320 to move until the contact 321 of the corresponding control switch 320 abuts against or separates from the corresponding contact portion 110, so as to turn off the sterilization module 200. The control switch 320 closes or opens the sterilization module 200 by the abutment or separation of its own contact 321 and the contact portion 110 of the base 100. Setting the control switch 320 as a mechanical control switch category can improve the accuracy of the control switch 320.

[0067] In the third case, the control switch 320 can determine whether the light-shielding member 310 has an action of moving towards the cleaning surface. If so, it closes the sterilization module 200; otherwise, it opens the sterilization module 200.

[0068] In some embodiments of the present invention, as Figure 6 shown, an installation cavity is provided on the base 100; the sterilization module 200 includes: an ultraviolet germicidal lamp 210, a quartz glass 220, and a lamp holder 230; the lamp holder 230 is provided on the base 100 and has an installation cavity, the ultraviolet germicidal lamp 210 is installed in the installation cavity and its power is greater than or equal to a preset power, and the quartz glass 220 covers the opening of the installation cavity. Through the cooperation of the high-power ultraviolet germicidal lamp 210 and the quartz glass 220, it can ensure that the sterilization is more thorough during the cleaning process, and even achieve a killing effect instantly, which is beneficial to further bring a real health guarantee to the cleaned environment. Among them, the quartz glass 220 can not only reduce the loss of ultraviolet light, but also further ensure the tightness of the installation cavity, playing a protective role for the ultraviolet germicidal lamp 210. Optionally, the front roller 130 is provided at the front end of the lamp holder 230. As an example, the ultraviolet germicidal lamp 210 is electrically connected to the battery pack through Figure 6 the conductive plug 240 shown. Optionally, the preset power can be 18w.

[0069] Furthermore, in some embodiments of the present invention, as Figure 1 and Figure 6As shown, a horizontal plate 120 is provided at the front end of the lamp holder 230. The horizontal plate 120 is located between the first light-shielding plate 311 and the third light-shielding plate 313 and forms a light-shielding cavity together with the light-shielding member 310. The orifice of the installation cavity is located in the light-shielding cavity. It can be understood that the lower surface of the horizontal plate 120 is flush with the lower surfaces of the first light-shielding plate 311, the second light-shielding plate 312, and the third light-shielding plate 313. Of course, when a protective strip 314 is provided at the lower end of the second light-shielding plate 312, the lower surface of the horizontal plate 120 is flush with the lower surfaces of the first light-shielding plate 311, the protective strip 314, and the third light-shielding plate 313, which can ensure that the lower surfaces of these four are on the same plane. In this way, when the light-shielding member 310 contacts the surface to be cleaned, the light-shielding member 310 can cooperate with the horizontal plate 120 and the surface to be cleaned to place the sterilization module 200 in a relatively enclosed space, thereby effectively preventing the sterilization module 200 from leaking sterilizing light. Optionally, step surfaces are provided at the front ends of the first light-shielding plate 311 and the third light-shielding plate 313, and the horizontal plate 120 is lapped on these step surfaces.

[0070] In some embodiments of the present invention, as Figure 1 shown, an ambient light member 400 is further provided on the base 100. The ambient light member 400 is provided on the left and right sides of the light-shielding member 310. The ambient light member 400 can improve the aesthetics of the base structure 10 and enhance the user experience. Optionally, the number of the ambient light members 400 is 2 and they are located outside the light-shielding cavity. One of the ambient light members 400 is distributed close to the first light-shielding plate 311, and one of the ambient light members 400 is distributed close to the third light-shielding plate 313. Optionally, the ambient light member 400 is electrically connected to the rotary touch switch 180, and the rotary touch switch 180 is used to control the on and off of the ambient light member 400. Optionally, the ambient light members 400 are symmetrically distributed about the central axis of the base 100.

[0071] An embodiment of the present invention provides a cleaning device, which includes the base structure 10 described in any one of the above.

[0072] As an example, the cleaning device further includes an upright handle 50 operably connected to the base 100. The upright handle 50 can be used to set the handheld part and modules such as the controller and power supply of the cleaning device. The cleaning device also has a vacuum suction source, a garbage passage, a roller brush housing 190, a roller brush scraper, a sewage tank 40, a water tank 30, a fluid dispenser, and a roller brush 170 installed on the base 100 and other structures. It should be noted that the upright handle 50 being operably connected to the base 100 means that the upright handle 50 is detachably and / or rotatably connected to the base 100. In addition, the upright handle 50 includes a handheld part and also an installation part for installing components such as a vacuum suction source, the water tank 30, and the sewage tank 40.

[0073] The vacuum suction source and the clean water tank 30 can be selectively arranged on the upright handle 50. The sewage tank 40 can be selectively arranged on the upright handle 50 or the base 100. The vacuum suction source is used to generate suction to suck fluids including gaseous and liquid fluids, as well as garbage and dust, etc. from the ground into the sewage tank 40 through the garbage passage. The roller brush cover 190 of the cleaning device is arranged on the base 100, and the roller brush cover 190 at least partially surrounds the roller brush 170, so that a nozzle structure can be formed between the roller brush cover 190 and the roller brush 170. The cleaning device further includes a roller brush motor, which is installed in the base 100 and provides power to drive the roller brush 170 to rotate for mopping the ground. The nozzle is communicated with the sewage tank 40 through the garbage passage, so that the fluid or garbage on the ground enters the garbage passage through the nozzle.

[0074] The cleaning device further includes a fluid dispenser. The fluid dispenser can be arranged on the upright handle 50 or the base 100. A relatively good optional way is to arrange it in the base 100. The fluid dispenser is communicated with the clean water tank 30 through a fluid transmission path, and is used to apply the clean water in the clean water tank 30 to the surface of the roller brush 170 or the surface to be cleaned through the transmission of the transmission pipeline.

[0075] In order to make the cleaning efficiency of the cleaning device higher, a roller brush scraping strip is arranged on the cleaning device. The roller brush scraping strip can be formed on the roller brush cover 190 or can be formed on the base 100. The roller brush scraping strip can be integrally formed with the base 100, and the roller brush scraping strip can also be integrally formed with the roller brush cover 190. Of course, the roller brush scraping strip can also be provided on the base 100 or the roller brush cover 190 as a separately detachable component. The roller brush scraping strip is mainly used to scrape off the residual dust or liquid on the roller brush 170. So that the vacuum suction source can suck the dirt into the sewage tank 40 as much as possible to improve the cleaning efficiency. In order to make the disassembly and assembly of the roller brush cover 190 more convenient, the roller brush cover 190 can be detachably arranged on the base 100 by means of spring buckles. In order to keep the inside of the base 100 clean, a sealing layer structure can be formed on the inner side surface of the roller brush cover 190 to prevent the dirt from polluting the inside of the base 100. In order to facilitate observing the cleaning effect and the working state of the roller brush 170, the roller brush cover 190 can be made into a transparent shape.

[0076] For the cleaning device as described above, when the light-shielding member 310 of the base structure 10 is placed on the surface to be cleaned, the control switch 320 can turn on the sterilization module 200. Then, during the process of the sterilization module 200 sterilizing the surface to be cleaned, since the light-shielding member 310 surrounds the sterilization module 200 on all sides, it can cooperate with the surface to be cleaned to place the sterilization module 200 in a relatively enclosed space. In this way, the sterilization light of the sterilization module 200 can be effectively blocked from leaking to the outside of the base structure 10 without the light-shielding member 310 leaving the surface to be cleaned. Additionally, once at least a part of the light-shielding member 310 leaves the surface to be cleaned and moves in the direction close to the surface to be cleaned, the working state of the control switch 320 will be adjusted from the on state to the off state, thereby turning off the sterilization module 200 and preventing the sterilization light generated by the sterilization module 200 from leaking through the gap between the light-shielding member 310 and the surface to be cleaned, providing a real guarantee for the health of the cleaned environment.

[0077] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity in description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0078] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
