Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner floor brush technology, and more particularly to a liquid floor brush structure that can automatically spray and dry based on dust and fungus detection. Background Technology

[0002] Vacuum cleaners use a motor to drive an impeller to rotate at high speed, creating a momentary vacuum inside. Outside air, carrying dust, enters through the suction port under atmospheric pressure, and after multi-stage filtration, clean air is expelled. When cleaning floors, the vacuum cleaner uses a rotating roller brush on the floor brush to rub and remove stubborn stains and gather dust.

[0003] In indoor spaces with heavy dust accumulation, cleaning the floor with a vacuum cleaner's floor brush can easily cause dust to be stirred up due to human movement, machine vibration, and airflow disturbance caused by negative pressure suction. On the one hand, the dust will settle back down on the floor after cleaning, resulting in the floor brush not effectively cleaning the floor. On the other hand, it can easily lead to people inhaling dust and causing physical discomfort. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic liquid spraying floor brush structure based on dust and fungus detection, so as to solve the problem of poor cleaning effect and human health impact caused by dust on the floor during the floor cleaning process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic liquid-spraying floor brush structure based on dust and fungus detection, comprising:

[0006] The floor brush body is connected to the vacuum cleaner main unit via a connector tube, and the main controller is installed inside the vacuum cleaner main unit;

[0007] The water tank is fixedly installed on the floor brush body;

[0008] The spraying module includes a spray box, a diaphragm pump, a battery, and an atomizing nozzle. The spray box is detachably installed on the water storage tank. The battery powers the diaphragm pump. The inlet connector of the diaphragm pump is connected to a water guide hose. One end of the water guide hose passes through the side wall of the spray box and extends into the water storage tank. The outlet channel of the diaphragm pump is connected to the atomizing nozzle, which is fixedly installed on the spray box.

[0009] The detection module includes a dust-sensing PCB board and a dust-sensing lamp. The dust-sensing PCB board is fixedly installed inside the spray box and is wirelessly connected to the main controller. The dust-sensing lamp is fixedly installed on the spray box.

[0010] As a further description of the above technical solution:

[0011] The detection module also includes a Wood's lamp, which is fixedly mounted on the spray box and shines on the ground in front of the brush body.

[0012] As a further description of the above technical solution:

[0013] A magnet is installed at the bottom of the spray box, and an iron plate is installed on the surface of the water storage tank, with the position of the iron plate corresponding to the magnet.

[0014] As a further description of the above technical solution:

[0015] The spray box includes a first box body and a first top cover. The diaphragm pump is fixedly installed in the first box body, and the first top cover closes the opening at the top of the first box body.

[0016] As a further description of the above technical solution:

[0017] The water storage tank includes a second tank body and a second top cover. The second tank body is fixedly installed on the floor brush body, and the second top cover closes the top opening of the second tank body. A water injection hole is provided on the second top cover.

[0018] As a further description of the above technical solution:

[0019] The rubber stopper is inserted into the water injection hole.

[0020] As a further description of the above technical solution:

[0021] The bottom surface of the second tank is provided with a recessed part, and water guide hoses are symmetrically arranged on both sides of the diaphragm pump.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In this invention, when the floor brush body is cleaning the floor, the main controller controls the detection module to start detection. The detection module illuminates the space in front of the floor brush cleaning direction through the dust sensor light on the spray box. When the dust concentration in the air in the front space is greater than the set threshold, the dust sensor PCB board issues a spraying command and controls the diaphragm pump to start. The liquid in the water tank is drawn into the diaphragm pump through the water guide hose and continuously sprayed from the atomizing nozzle to the front of the floor brush, thereby effectively controlling the dust concentration in the air and solving the problem of poor cleaning effect and human health caused by dust on the floor during the floor brush cleaning process.

[0024] 2. In this invention, the detection module also includes a Wood's lamp, which illuminates the ground in front of the floor brush body. The signal processor of the Wood's lamp is connected to a dust sensing PCB board. When the Wood's lamp detects fungi on the ground in front of the floor brush body, water will not be sprayed even if the dust concentration exceeds a set threshold, in order to avoid the spread of fungal spores and to prevent the environment from becoming humid and promoting fungal growth.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0036] Example 1

[0037] Please see Figure 1-3 This invention provides a technical solution: an automatic liquid-spraying floor brush structure based on dust and fungus detection, comprising:

[0038] The floor brush body 1 is connected to the vacuum cleaner host through the connector tube 11. The vacuum cleaner host is equipped with a main controller.

[0039] Water storage tank 2 is fixedly installed on the floor brush body 1;

[0040] The spraying module 3 includes a spray box 31, a diaphragm pump 32, a battery, and an atomizing nozzle 33. The spray box 31 is detachably installed on the water storage tank 2. The battery is fixedly installed inside the spray box 31 and is used to power the diaphragm pump 32. The water inlet connector of the diaphragm pump 32 is connected to the water guide hose 321. One end of the water guide hose 321 passes through the side wall of the spray box 31 and extends into the water storage tank 2. The water outlet channel of the diaphragm pump 32 is connected to the atomizing nozzle 33, and the atomizing nozzle 33 is fixedly installed on the spray box 31.

[0041] The detection module includes a dust sensing PCB board 9 and a dust sensing lamp 91. The dust sensing PCB board 9 is fixedly installed inside the spray box 31 and is wirelessly connected to the main controller. The dust sensing lamp 91 is fixedly installed on the spray box 31.

[0042] Preferably, the battery is a rechargeable battery, and a charging connector is provided on the spray box 31. The battery is connected to the charging connector via a wire. After the spray module 3 is disassembled, the battery can be charged through the charging connector, facilitating the charging of the spray module 3.

[0043] The detection module also includes a Wood's lamp 92, which is fixedly mounted on the spray box 31 and shines on the ground in front of the brush body 1. The signal processor of the Wood's lamp 92 is connected to the dust sensing PCB board 9. When the Wood's lamp 92 detects fungi on the ground in front of the brush body 1, it will not spray water even if the dust concentration exceeds a set threshold, in order to avoid the spread of fungal spores and the formation of a humid environment that promotes fungal growth.

[0044] The spray box 31 includes a first box body 312 and a first top cover 313. The diaphragm pump 32 is fixedly installed inside the first box body 312, and the first top cover 313 closes the top opening of the first box body 312. The first top cover 313 can be fixed to the first box body 312 by means of snap-fit ​​or by means of adhesive.

[0045] The water storage tank 2 includes a second body 21 and a second top cover 22. The second body 21 is fixedly installed on the floor brush body 1, and the second top cover 22 closes the top opening of the second body 21. The second top cover 22 is provided with a water injection hole 221. Similarly, the second top cover 22 is installed to the second body 21 by means of snap-fit ​​or adhesive. The water storage tank 2 can be replenished with liquid through the water injection hole 221.

[0046] A rubber stopper 23 is inserted into the water injection hole 221. The rubber stopper 23 seals the water injection hole 221 by insertion, ensuring a tight seal.

[0047] Working principle: When the floor brush body 1 cleans the floor, the main controller controls the detection module to start detection. The detection module illuminates the space in front of the floor brush cleaning direction through the dust sensor light 91 on the spray box 31. When the dust concentration in the air in the front space is greater than the set threshold, the dust sensor PCB board 9 issues a spraying command and controls the diaphragm pump 32 to start. The liquid in the water tank 2 is drawn into the diaphragm pump 32 through the water guide hose 321 and continuously sprayed from the atomizing nozzle 33 to the front of the floor brush. The spraying duration can be set manually (specifically, it can be set to 3 seconds), thereby effectively controlling the dust concentration in the air and solving the problem of poor cleaning effect and human health caused by dust on the floor during the floor brush cleaning process.

[0048] The detection module essentially uses an optical scattering dust sensor to determine the dust concentration in the air in front of the floor brush. The dust sensing lamp 91 serves as the transmitter and receiver coaxially integrated with the sensor, such as the Sharp GP2Y1010 sensor. The light emitted by the dust sensing lamp 91 is obliquely directed towards the dust, and the scattered light is reflected back to the receiver and converted into an electrical signal. Finally, the signal processor on the dust sensing PCB board analyzes the electrical signal and calculates the dust concentration.

[0049] Example 2

[0050] Based on the above embodiments, the following improved technical solutions are made in this embodiment: a magnet 311 is provided at the bottom of the spray box 31, and an iron sheet is provided on the surface of the water storage tank 2, with the position of the iron sheet corresponding to the magnet 311.

[0051] The spray box 31 is magnetically fixed to the water storage tank 2, making it easy to disassemble and maintain.

[0052] Example 3

[0053] This embodiment further improves upon the above embodiment by providing the following technical solution: A recessed portion 211 is provided on the bottom surface of the second tank 21, and symmetrically arranged water guide hoses 321 are provided on both sides of the diaphragm pump 32. The recessed portion 211 on the bottom surface of the second tank 21 ensures that the bottom of the second tank 21 fits snugly against the upper surface of the brush body 1, improving the installation stability of the water storage tank 2. The recessed portion 211 also allows the liquid level inside the second tank 21 to drop, forming two independent cavities. The diaphragm pump 32 is a dual-inlet diaphragm pump, ensuring a stable liquid supply from the diaphragm pump 32.

[0054] In addition, the water guiding hoses 321 extending from both sides of the spray box 31 improve the installation stability of the spray box 31 on the water storage tank 2 and prevent the spray box 31 from detaching from the water storage tank 2.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
