Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a floor washing assembly with self-cleaning function and a floor washing machine. BACKGROUND

[0002] At present, a floor washing machine with self-cleaning function appears, for example, the Chinese utility model patent with the authorization announcement number CN215191300U, by setting a special cleaning base, when cleaning, water is poured from a water tank to flush the roller brush, the water after flushing flows into the cleaning tank of the cleaning base, the motor assembly is started to drive the roller brush to roll and wash, so that the cleaning water in the cleaning tank washes the roller brush; after cleaning, the water tank stops water, the motor assembly drives the roller brush to rotate and dry the water, and at the same time, the water suction mechanism is started, the sewage in the cleaning tank is sucked away through the sewage pipeline, and finally falls into the sewage tank to realize sewage recycling. The floor washing machine with self-cleaning function does not need to be manually poured sewage after each cleaning, but can be poured after the sewage in the sewage tank is full, which improves the convenience of use.

[0003] However, the existing floor washing machine with self-cleaning function still has the following technical problems: a special cleaning base needs to be set, which increases the complexity of the structure; secondly, only the roller brush can be cleaned, but the inside of the floor washing machine cannot be cleaned, and we know that the working condition of the floor washing machine is generally wet mopping the ground, and the suction source sucks in gas-liquid mixture, so a gas-liquid separation structure needs to be set before the suction source, the separated sewage is recycled to the sewage tank of the gas-liquid separation structure, and the separated gas is discharged through the suction source. After the gas-liquid mixture passes through the internal components of the floor washing machine, the inside of the floor washing machine is relatively dirty, bacteria are easy to breed, and there is a strong odor after a long time; finally, the cleaning medium at room temperature is used for cleaning, and the cleaning effect is not good. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the defects of the prior art, and to provide a floor washing assembly with self-cleaning function, which does not need to set a special cleaning base, has good cleaning effect, and can significantly reduce the breeding of internal bacteria and odor; and a floor washing machine with self-cleaning function, which does not need to set a special cleaning base, has good cleaning effect, and can significantly reduce the breeding of internal bacteria and odor.

[0005] Compared with existing technologies, this invention proposes a floor cleaning component with self-cleaning function, including a cleaning section, a gas-liquid separation structure, and a clean water tank. The cleaning section is connected to the gas-liquid separation structure through a wastewater flow channel, used to transport wastewater from the cleaning section and / or the surface to be cleaned to the gas-liquid separation structure. The gas-liquid separation structure is also provided with a gas flow channel for connection to a suction source. The cleaning section is characterized by having a self-heating steam generator and a hot water container. The clean water tank is connected to both the self-heating steam generator and the hot water container through a cold water delivery channel, used to provide a reaction fluid for the self-heating steam generator and a cleaning medium for the hot water container. The self-heating steam generator has a closed reaction chamber and is in thermal contact with the hot water container, used to transfer the heat generated by the self-heating steam generator to the cleaning medium in the hot water container. The wastewater flow channel is also provided with a first spray hole. The hot water container is connected to the first spray hole of the wastewater flow channel through a first hot water delivery channel. The first spray hole is used for independent water spraying and / or for water spraying in conjunction with suction from a suction source.

[0006] The aforementioned self-heating steam generating assembly with a closed reaction chamber refers to a self-heating steam generating assembly that is entirely located within a closed chamber, where the fluid active material and the fluid undergo an exothermic reaction. The closed state is a sealed or near-sealed state.

[0007] Compared with the prior art, the present invention has the following advantages when adopting the above structure: Firstly, the self-cleaning floor cleaning component of the present invention does not require a dedicated cleaning base, thus simplifying the structure. Secondly, a first water spray hole is provided on the sewage channel to clean the sewage channel. Thirdly, since the sewage channel is the foremost inlet and flow passage of the gas-liquid mixture, if water is sprayed in while suction is applied, the gas-liquid mixture cleaning the sewage channel will be drawn into the gas-liquid separation structure, allowing the sewage to be recycled and preventing contamination of the external environment. Fourthly, the gas-liquid mixture formed during the cleaning of the sewage channel becomes increasingly cleaner with each cleaning process. When this clean gas-liquid mixture is drawn into the gas-liquid separation structure by the suction source, it will affect the gas-liquid separation structure. The longer the cleaning time, the more obvious the cleaning effect. If the sewage channel is cleaned, the sewage recovered by the gas-liquid separation structure is poured out, and then clean water is sprayed into the sewage channel while the suction source is used for suction, this will have a better cleaning effect on the gas-liquid separation structure, making the inside of the floor cleaning component cleaner and significantly reducing the growth of bacteria and odors. Fifth, the entire cleaning process is completed automatically without manual rinsing, greatly reducing the user's cleaning workload. Finally, and more importantly, the cleaning medium is heated by self-heating. Using the heated cleaning medium to rinse the sewage channel not only has a better cleaning and sterilization effect than the cleaning medium at room temperature, but is also more convenient to use than electric heating.

[0008] As a preference, the first water spraying hole is arranged at a position close to the cleaning part of the sewage flow channel. This arrangement can better clean the sewage flow channel.

Spraying hot water to the mop cleaning assembly and / or the surface to be cleaned can not only achieve better cleaning and sterilization of the surface to be cleaned, but also achieve certain cleaning and sterilization of the cleaning part.

[0011] As a preference, the first hot water conveying channel is provided with a first pump, and the second hot water conveying channel is provided with a second pump. This arrangement can facilitate the delivery of hot water to the sewage flow channel and the cleaning part, and can control the flow in the two hot water conveying channels respectively.

This arrangement can hide the cold water conveying channel and the first hot water conveying channel inside the cleaning part, and the structure is simpler and more compact.

[0013] As a preference, the second hot water conveying channel is also arranged inside the cleaning part. This arrangement can hide the second hot water conveying channel inside the cleaning part, and the structure is simpler and more compact.

[0014] As a preference, the self-heating steam generating assembly is embedded in the hot water container to achieve thermal contact between the two. This arrangement can make the structure more simple and compact.

[0015] As a preference, the mop cleaning assembly is arranged at one side of the cleaning part, the other side of the cleaning part has a cavity, and the self-heating steam generating assembly and the hot water container are both installed in the cavity.

[0045] The gas-liquid separation structure 37 can be realized by using the existing technology, in this embodiment, the gas-liquid separation structure 37 includes a sewage tank 43 and two separation units arranged in the sewage tank 43, the two separation units are arranged axially in up and down directions; the first separation unit 44 adopts a separation cover structure, and the second separation unit 45 adopts a centrifugal separation structure; the gas-liquid mixture entering the sewage flow channel 38 is blocked by the separation cover of the first separation unit 44, so that most of the sewage is separated out and remains in the sewage tank, the gas-liquid mixture separated by the first separation unit 44 continues to move upward under the action of the suction source 42 and enters the second separation unit 45, further gas-liquid separation is realized by the centrifugal rotation of the second separation unit 45, so that more sewage is separated out and remains in the sewage tank 43, and the separated gas is sucked out by the suction source 42 through the gas flow channel 39 of the second separation unit 45.

[0046] The working principle of the self-cleaning floor cleaning component of this invention is as follows: The third pump 46 is activated, and the fluid drawn from the outlet 33 of the clean water tank 3 is transported through the first pipe 21 to the hot water container 7 as a cleaning medium. It then sequentially passes through the second pipe 22, the first adapter 19, the second adapter 20, and the third pipe 23 to the cold water inlet 24 of the heating pack dispensing chamber 14 as a reaction fluid. The reaction fluid entering the heating pack dispensing chamber 14 enters the self-heating container 12 through the first through-hole 15, covering the heating pack 36. Then, the third pump 46 stops working. The heating pack 36 in the self-heating container 12 undergoes an exothermic reaction upon contact with the reaction fluid. The heat generated by the exothermic reaction is transferred to the hot water container 7 to form hot water. The first pump 25 is activated, and the hot water is transported through the first hot water delivery channel 41 to the first spray hole 40 of the sewage channel 38. After being sprayed out, it can clean the sewage channel 38. If this is combined with suction... When the source 42 performs suction, the gas-liquid mixture of the cleaning sewage flow channel 38 will be drawn into the gas-liquid separation structure 37 to collect the sewage, preventing it from flowing out and thus avoiding contamination of the external environment. When the second pump 30 is started, hot water will be delivered through the second hot water delivery channel, that is, through the fourth pipe 28, the third adapter 26, the fourth adapter 27 and the fifth pipe 29 in sequence, to the second spray hole 11 of the protective cover 10 for spraying out to clean the surface to be cleaned. When it is necessary to replace or remove the heating pack 36, simply press the top of the heating pack delivery chamber 14 to make the heating pack delivery chamber 14 pop out automatically. This will cause the heating pack 36 to pop up and isolate it from the reaction fluid, thereby stopping the exothermic reaction. After popping out, the heating pack 36 can be replaced through the second through hole 16 on the side of the heating pack delivery chamber 14. Pressing the top of the heating pack delivery chamber 14 again will cause the heating pack delivery chamber 14 to retract downwards.
