CROSS-REFERENCE TO RELATED APPLICATION

The disclosure is a National Stage Filing of the PCT International Application No. PCT/CN2023/085264 filed on Mar. 30, 2023, which claims priority to Chinese Patent Application No. 202310301109.8 filed to the China National Intellectual Property Administration on Mar. 23, 2023 and entitled “Cleaning Device”, the disclosure of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The disclosure relates to the technical field of cleaning systems, and in particular to a cleaning device.

BACKGROUND

With the improvement of living standards, auxiliary cleaning devices for household hygiene come into being. These cleaning devices may reduce the amount of labor paid by users in household cleaning, so the devices are widely favored by the current society.

Most of the existing cleaning devices can only meet one use scenario. For example, a vertical cleaning device can only clean a floor, or a carpet on the floor, but cannot clean a desktop above the floor, etc. A hand-held cleaning device may be used to clean the desktop above the floor, car interiors, etc. However, if the floor and the carpet need to be cleaned, a user needs to squat down to operate the device, and the long-term use experience is poor. Moreover, if multi-scenario use is required, the user needs to purchase a variety of cleaning devices, which may cause a certain burden on the economy of the user and storage space.

SUMMARY

In view of the shortcomings of a related art, the disclosure aims to provide a cleaning device. The cleaning device adds an accessory to an existing vertical cleaning device, so that a user is able to hold the accessory to suck dirt, thus meeting the requirements of multi-scenario use of the cleaning device, a floor and a to-be-cleaned surface such as a carpet on the floor is cleaned using a floor brush, and the to-be-cleaned surface such as a desktop, a windowsill and a sofa above the floor also are cleaned using the accessory.

In order to achieve the above purpose, an embodiment of the disclosure is as follows: a cleaning device including a machine body, a fluid recovery system, a floor brush, an accessory and a first control valve component. The fluid recovery system includes a fluid recovery container and a suction pipe. The floor brush includes a suction port, the suction port is configured for being in fluid communication with the fluid recovery system, and the floor brush is connected with the machine body.

The first control valve component is arranged among the suction pipe, the suction port and the dirt suction pipe, and the first control valve component is configured to control the suction pipe to be selectively communicated with the suction port or the dirt suction pipe, so that the cleaning device is switched between a floor brush mode and an accessory mode. In the related art, the floor brush mode and the accessory mode are switched mostly by plugging and unplugging the accessory. Thus, the user needs to plug and unplug the accessory frequently, which is very inconvenient. Moreover, when the floor brush mode is needed, the unplugged accessory has nowhere to put and is inconvenient to store, and residual dirt in the accessory may cause secondary pollution to the cleaning device and the floor every time the accessory is disassembled, thus reducing the user experience. The cleaning device provided by the disclosure is provided with the first control valve component to switch between the floor brush mode and the accessory mode, so that the accessory does not need to be plugged and unplugged frequently. When the floor brush mode is used, the accessory is able to be stored on the machine body, so that the operation is convenient, frequent disassembly of the accessory is avoided, and the residual dirt in the accessory is avoided from causing secondary pollution to the cleaning device and the floor to affect the user experience.

In one embodiment implementation, the first control valve component includes a valve body and a valve core. The valve body is provided with a first branch, a second branch and a main passage.

At this time, the cleaning device not only sucks the dirt, but also sprays liquid on the to-be-cleaned surface to achieve more effective and cleaner cleaning.

In one embodiment implementation, a pressure switch is arranged between the water pump and the second control valve component. A mechanical switch is arranged on the accessory to control whether the accessory sprays water. When the mechanical switch is not turned on and the cleaning device is in the accessory mode, the water pumped by the water pump cannot be released, which is able to exert pressure on the water pump and affect the service life of the water pump. At this time, a pressure switch is arranged between the water pump and the second control valve component, and the pressure switch is able to detect the pressure exerted by the water on the water pump. When the pressure reaches a certain value, the pressure switch is able to control the water pump to cut off, thus protecting the water pump.

In one embodiment implementation, the cleaning device further includes a fluid delivery system and a third control valve component. The fluid delivery system includes a fluid supply container, a water pump and a heating mechanism.

As shown in FIG. 4, when the valve core 420 is in the second position, the suction pipe 120 is communicated with the dirt suction pipe 301 of the accessory 300. At this time, the cleaning device 1000 is in the accessory mode, and the dirt suction port 322 (FIG. 6) in the accessory 300 suck the dirt on the desktop, so that the dirt on the desktop sequentially passes through the dirt suction port 322, the dirt suction pipe 301, the second branch 413, the main passage 411 and the suction pipe 120 to enter the fluid recovery container 110.

As shown in FIG. 5, in one embodiment implementation, the first control valve component 400 further includes an operating part 430. The operating part 430 is manually controlled by the user to switch between the floor brush mode and the accessory mode. The operating part 430 is connected with the valve core 420, and the valve core 420 is moved between the first position and the second position by controlling the operating part 430. Specifically, the operating part 430 is a knob, and the user realizes switching between the floor brush mode and the accessory mode by rotating the operating part 430. In other implementations, the operating part 430 is also able to be another structure, which is not specifically limited here. In another embodiment implementation, a driving apparatus such as a motor is installed on the operating part 430, a user operation button is arranged on the machine body 100, and the user operation button is electrically connected with the driving apparatus. The user is able to control the start of the driving apparatus by operating the user operation button, so that the operating part 430 is driven to move, so as to realize electric control of the operating part 430. At this time, the user does not need to manually control the operating part 430, which makes the cleaning device 1000 more intelligent and makes the user experience better.

As shown in FIG. 1, the machine body 100 sequentially includes a holding part 101, a connecting rod 102 and a main body 103 of the machine body from top to bottom, and the connecting rod 102 is connected with the holding part 101 and the main body 103 of the machine body.

Specifically, the connecting rod 102 is provided with a hoop 104 having an opening, and the hand-held unit 320 is clamped into the hoop 104 in an interference fit manner through the opening, so as to fix the hand-held unit 320 on the machine body 100. The hoop 104 is arranged on the connecting rod 102, and located below the holding part 101. Compared with being arranged on the main body 103 of the machine body, the user is able to take the holding part 320 without bending over. In addition, the connecting rod 102 is the narrowest part on the cleaning device 1000, and the accessory 300 is arranged thereon, which does not occupy other areas and is suitable. A fixing member 105 with a magnetic part is arranged on the tube 310, and another magnetic part is also arranged in a corresponding position on the main body 103 of the machine body to magnetically attract the fixing member 105. The tube 310 is connected with the machine body 100 by magnetic attraction, and the tube 310 is able to be detached from the machine body 100 without the user bending over, which is convenient. In other implementations, the mode of connecting the tube 310 and the hand-held unit 320 to the machine body 100 is not limited to the above-mentioned mode, and other connection modes in the related art is adopted, which is not specifically limited here.

In one embodiment implementation, the tube 310 is a retractable spring pipe. Compared with a non-retractable tube 310 in the related art, if the use range of the accessory 300 is required to be wider, it is necessary to set a longer tube 310, which is able to lead to the tube 310, when the floor brush mode is used without using the accessory 300, being too long to drag on the floor after the machine body 100 is tilted, thus polluting the newly cleaned floor. When the tube 310 is the retractable spring pipe, the use range of the accessory 300 is able to be expanded when the accessory 300 is used, and when the floor brush mode is used without using the accessory 300, the accessory 300 is not dragged to the floor to pollute the newly cleaned floor.

As shown in FIG. 6, the hand-held unit 320 includes a shell 321, a dirt suction port 322 arranged at the front end of the shell 321, bristles 323 and a wiper strip 324. The bristles 323 are arranged behind the dirt suction port 322, and the wiper strip 324 is arranged in front of the dirt suction port 322. The wiper strip 324 is arranged in front of the dirt suction port 322, which is able to lead the dirt on the desktop cleaned by the hand-held unit 320 to enter the dirt suction port 322, and the dirt is sucked more cleanly at this time.

The hand-held unit 320 also includes a mechanical switch 325 and an accessory nozzle 326, and the user is able to control the accessory nozzle 326 to spray liquid through the mechanical switch 325. Only when the user turns on the mechanical switch 325 will the accessory nozzle 326 spray the liquid. The user has more choices and greater user-friendliness is achieved.

As shown in FIG. 2, in the implementation, the first control valve component 400 is arranged on the floor brush 200, which is able to reduce the volume of the machine body 100 and provide a larger accommodation space for the fluid supply container and the fluid recovery container 110, so that the fluid supply container and the fluid recovery container 110 is able to be provided with larger capacities, and the single operation time of the cleaning device 1000 is improved. At this time, the accessory 300 is connected with the floor brush 200, and the accessory 300 is provided with a latch component 330. A groove 201 is formed in a corresponding position on the floor brush 200 to accommodate the latch component 330, and the user is able to disassemble and assemble the accessory 300 and the floor brush 200 by operating the latch component 330. The connection structure using the latch component 330 is able to improve the connection strength between the accessory 300 and the floor brush 200 while facilitating disassembly, and avoid the accessory 300 from easily falling off the cleaning device 1000 when the accessory 300 is dragged to clean the desktop with its extreme distance. At this time, the accessory 300 is also able to be detachably connected with the first control valve component 400, and the accessory 300 and the first control valve component 400 is able to be connected in a nested manner. For example, an end part of the second branch 413 of the first control valve component 400 is a hollow cylinder, and the end part of the accessory 300 connected with the second branch 413 is a hollow cylinder with an outer diameter equivalent to the inner diameter of the cylinder at the end part of the second branch 413, so that the end part of the accessory 300 is able to be inserted into the end part of the second branch 413 to realize the connection between the two. The structure facilitates disassembly and assembly of the accessory 300 and the first control valve component 400. When the user does not need to use the accessory 300, the accessory 300 is disassembled conveniently, and the dirt suction pipe 301 is cleaned by disassembling the accessory 300. In other implementations, the first control valve component 400 is also able to be arranged on the machine body 100, and at this time, the accessory 300 is also connected with the machine body 100, so that the volume of the floor brush 200 is reduced.

As shown in FIG. 7, in one embodiment implementation, the cleaning device 1000 further includes a fluid delivery system and a second control valve component 500. The fluid delivery system includes a fluid supply container and a water pump 130. The floor brush 200 further includes a floor brush nozzle 220, and the floor brush nozzle 220 is configured for being in fluid communication with the fluid delivery system. The accessory 300 further includes a water outlet pipe 302, and the water outlet pipe 302 is configured for being in fluid communication with the fluid delivery system. The second control valve component 500 is arranged among the water pump 130, the water outlet pipe 302 and the floor brush nozzle 220, and the second control valve component 500 is configured to control water pumped by the water pump 130 to selectively flow to the water outlet pipe 302 or the floor brush nozzle 220, so that the cleaning device 1000 is switched between the floor brush mode and the accessory mode. At this time, the cleaning device 1000 is able to not only suck the dirt, but also spray the liquid on the floor or desktop to achieve more effective and cleaner cleaning. In the implementation, the second control valve component 500 is an electromagnetic valve, which is able to be controlled via a main control board without manual control by the user, and is more intelligent. When the second control valve component 500 is turned on, the water pumped by the water pump 130 flows to the water outlet pipe 302. When the second control valve component 500 is not turned on, the water pumped by the water pump 130 flows to the floor brush nozzle 220.

As shown in FIG. 8, in another embodiment implementation, a pressure switch 140 is arranged between the water pump 130 and the second control valve component 500. As shown in FIG. 6, a mechanical switch 325 is arranged on the accessory 300 for the user to control whether the accessory 300 sprays the water. When the mechanical switch 325 is not turned on and the cleaning device 1000 is in the accessory mode, the water pumped by the water pump 130 cannot be released, which is able to exert pressure on the water pump 130 and affect the service life of the water pump 130. At this time, a pressure switch 140 is arranged between the water pump 130 and the second control valve component 500, and the pressure switch 140 is able to detect the pressure exerted by the water on the water pump 130. When the pressure reaches a certain value, the pressure switch 140 is able to control the water pump 130 to cut off, thus protecting the water pump 130.

As shown in FIG. 9, in one embodiment implementation, the cleaning device 1000 further includes a fluid delivery system and a third control valve component 600. The fluid delivery system includes a fluid supply container, a water pump 130 and a heating mechanism 150. The floor brush 200 further includes a floor brush nozzle 220, and the floor brush nozzle 220 is configured for being in fluid communication with the fluid delivery system. The third control valve component 600 is arranged among the water pump 130, the heating mechanism 150 and the floor brush nozzle 220, and the third control valve component 600 is configured to control the water pumped by the water pump 130 to selectively flow to the heating mechanism 150 or the floor brush nozzle 220. The heating mechanism 150 is configured to heat the water entering the heating mechanism 150 into steam or hot water with a preset temperature. The heating mechanism 150 is communicated with the floor brush nozzle 220, so that the steam or hot water with the preset temperature heated by the heating mechanism 150 flows out through the floor brush nozzle 220. At this time, the floor brush 200 of the cleaning device 1000 is able to spray cold water, hot water or steam to the floor to meet different cleaning requirements. For example, when the floor is greasy, the third control valve component 600 is turned on, so that the water pumped by the water pump 130 flows to the heating mechanism 150. By controlling the heating power of the heating mechanism 150, the heating mechanism 150 heats the water into the hot water with the preset temperature, and the hot water makes it easier to clean the greasy floor. Or when the user needs to sterilize the floor or a rolling brush by steam, the third control valve component 600 is turned on, so that the water pumped by the water pump 130 flows to the heating mechanism 150, and the heating mechanism 150 heats the water into the steam to sterilize the floor or the rolling brush by controlling the heating power of the heating mechanism 150.

In the implementation, the cold water, hot water and steam all flow out through the floor brush nozzle 220. In other implementations, a steam nozzle is able to be additionally arranged to spray the steam specially. At this time, it is realized that the steam is sprayed while the cold water is sprayed, and steam sterilization is performed while the floor is cleaned. At this time, a fourth control valve component needs to be additionally arranged between the heating mechanism 150 and the steam nozzle, which is configured to selectively deliver the steam to the steam nozzle and deliver the hot water to the floor brush nozzle 220.

In the implementation, the third control valve component 600 is an electromagnetic valve, which is controlled via the main control board without manual control by the user, and is more intelligent. When the third control valve component 600 is turned on, the water pumped by the water pump 130 flows to the heating mechanism 150 first and then flows to the floor brush nozzle 220. When the third control valve component 600 is not turned on, the water pumped by the water pump 130 directly flows to the floor brush nozzle 220.

As shown in FIG. 10, in another embodiment implementation, a one-way valve 160 is arranged between the third control valve component 600 and the heating mechanism 150, which is configured for preventing the hot water in the heating mechanism 150 from flowing back and damaging the third control valve component 600.

As shown in FIG. 11, in yet another embodiment implementation, a temperature sensor 170 is arranged between the heating mechanism 150 and the floor brush nozzle 220. The temperature sensor 170 is configured for detecting whether the temperature of the liquid flowing out of the heating mechanism 150 reaches the preset temperature, and if not reaching the preset temperature, increasing the heating temperature of the heating mechanism 150 to ensure that the hot water keeps the preset temperature continuously. In other implementations, the temperature sensor 170 is also able to be arranged on the floor brush nozzle 220 or the rolling brush, so long as the temperature of the hot water flowing out of the heating mechanism 150 is sensed, which is not specifically limited here.

As shown in FIG. 12, in one embodiment implementation, the cleaning device 1000 is able to include both the second control valve component 500 and the third control valve component 600. At this time, the second control valve component 500 is arranged among the water pump 130, the water outlet pipe 302 and the third control valve component 600. The second control valve component 500 is configured to control the water pumped by the water pump 130 to selectively flow to the water outlet pipe 302 or the third control valve component 600. The third control valve component 600 is respectively connected with the floor brush nozzle 220 and the heating mechanism 150, and is configured to control the water flowing out of the third control valve component 600 to selectively flow to the floor brush nozzle 220 and the heating mechanism 150. At this time, when the cleaning device 1000 is in the floor brush mode, the cold water, hot water or steam is able to be sprayed on the floor. When the cleaning device 1000 is in the accessory mode, the cold water is able to be sprayed on the desktop.

As shown in FIG. 13, in another embodiment implementation, the positions of the second control valve component 500 and the third control valve component 600 is able to be changed. At this time, the third control valve component 600 is arranged among the water pump 130, the heating mechanism 150 and the second control valve component 500. The third control valve component 600 is configured to control the water pumped by the water pump 130 to selectively flow to the heating mechanism 150 or the second control valve component 500. The second control valve component 500 is respectively connected with the floor brush nozzle 220 and the water outlet pipe 302, and is configured to control the water flowing out of the second control valve component 500 to selectively flow to the floor brush nozzle 220 and the water outlet pipe 302. At this time, when the cleaning device 1000 is in the floor brush mode, the cold water, hot water or steam is able to be sprayed on the floor. When the cleaning device 1000 is in the accessory mode, the cold water is able to be sprayed on the desktop.

The cleaning device 1000 provided by the disclosure adds the accessory 300 to the existing vertical cleaning device, so that the user is able to hold the accessory 300 to suck the dirt, thus meeting the requirements of multi-scenario use of the cleaning device 1000, the floor and the to-be-cleaned surface such as the carpet on the floor is cleaned using the floor brush 200, and the to-be-cleaned surface such as the desktop, the windowsill and the sofa above the floor also are cleaned using the accessory.

In addition, the cleaning device 1000 provided by the disclosure is provided with the first control valve component 400 to switch between the floor brush mode and the accessory mode, so that the accessory 300 does not need to be plugged and unplugged frequently. When the floor brush mode is used, the accessory 300 is able to be stored on the machine body 100, so that the operation is convenient, frequent disassembly of the accessory 300 is able to be avoided, and the residual dirt in the accessory 300 is avoided from causing secondary pollution to the cleaning device 1000 and the floor to affect the user experience.
