Detailed Description

To explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following detailed description is made with reference to the accompanying drawings.

Referring to fig. 1-2, a surface cleaning attachment 100 in accordance with the present disclosure is shown and described. The surface cleaning attachment 100 generally comprises a cleaner head 10 adapted to be moved over a surface to be cleaned and capable of aspirating a dirty liquid air mixture, a coupling body 20, a dirty liquid tank 30 and an outlet duct 40. The lower portion of the coupling body 20 is rotatably coupled to the suction head 10 of the suction head 10. The soil solution tank 30 is detachably mounted on the coupling body 20, and a lock mechanism 34 is mounted on the top of the soil solution tank 30, so that the user can release the entire soil solution tank 30 from the coupling body 20 by operating the lock mechanism 34. The outlet tube 40 is installed on the top of the coupling body 20. The outlet duct 40 is adapted to be in airflow communication with a vacuum cleaning apparatus, the outlet duct 40 being arranged to transmit vacuum suction from the vacuum cleaning apparatus to the cleaner head 10.

As shown in FIGS. 2 and 3, the suction head 10 comprises a housing 11 formed by an upper cover 111 and a bottom plate 112, a flexible suction nozzle 12 is provided at a central position of the bottom plate 112, and a pair of moving

wheels

113 and 114 are mounted on the front and rear portions of the bottom plate 112. As the cleaner head 10 is moved across the surface to be cleaned, the two pairs of

wheels

113 and 114 on the base 112 move the cleaner head 10 as a whole, whilst the suction nozzle 12 is now arranged to suck up the dirty liquid air mixture from the surface to be cleaned and feed it into a suction channel (not shown) in the housing 11.

As shown in fig. 2, the lower part of the coupling body 20 is provided with a lower port 21 of the housing 11 for air flow communication, and an upper port 22 located right above the lower port 21. The upper connector 22 is communicated with the air outlet pipe 40. The adapter 20 is adapted to receive the canister 30 in the area between the upper and lower junction ports.

The dirty liquid tank 30 shown in fig. 4 to 5 includes a tank body 31, a tank cover 32 detachably disposed above the tank body 31, a float 33, and a partition 35. The can lid 32 includes a first lid portion 321, a second lid portion 322, and a venting member 323 mounted between the first lid portion 321 and the second lid portion 322. The second cover portion 322 partially protrudes upward relative to the first cover 321. The user can pour the contaminated liquid in the can 31 by removing the can lid 32, and can wash the float 33 and the partition 35 at the same time.

As shown in fig. 6, which shows the internal layout of the dirty liquid tank 30. Wherein, a transverse wall 311 is arranged inside the tank 31, the transverse wall 311 divides the inner space of the tank 31 into a primary chamber 312 and a secondary chamber 313 which are adjacent left and right, the depth of the primary chamber 312 is less than that of the secondary chamber 313. Transverse wall 311 has a notch 3111 above, and an opening 3112 is opened at the lower part of transverse wall 311, and primary chamber 312 and secondary chamber 313 are communicated through notch 3111 and opening 3112, that is, dirty liquid-air mixture in primary chamber 312 flows into secondary chamber 313 through notch 3111 and opening 3112. The tank 31 is provided with an inlet pipe 314 integrally formed therein and located in the preliminary chamber 312, a lower end portion 3141 of the inlet pipe 314 is connected to the lower port 21 of the adapter 20, and the inlet pipe 314 can feed the dirty air mixture sucked from the suction nozzle 12 into the preliminary chamber 312. The upper port 3142 of the inlet pipe 314 is located above the upper edge of the transverse wall 311. The first cover portion 321 covers over the primary chamber 311 and the second cover portion 322 covers over the secondary chamber 313. The float 33 is mounted on the second cover part 322 and projects into the secondary chamber 313, moving with changes in the liquid level in the secondary chamber 313. The second cover portion 322 is further provided with a short exhaust pipe 324, the lower end of the short exhaust pipe 324 is an exhaust port 3241 directly communicating with the secondary chamber 313, and the opening of the exhaust port 3241 is arranged downward. The air exhausting member 323 has a passage 3231 therein, one end of the air exhausting member 323 is connected to the upper end of the air exhausting short pipe 324, and the other end 3232 is connected to the upper port 22 of the coupling body 20. The exhaust stub 324 can exhaust the air in the secondary chamber 313 to the outside of the chamber, i.e., into the exhaust 323, and then to the outlet duct 40 by the exhaust 323.

As shown in fig. 7, secondary chamber 313 includes a lower chamber portion 3131 and an upper chamber portion 3132 which are in communication with each other, float 33 being mounted in lower chamber portion 3131 (see fig. 6), a partition 35 being provided between upper chamber portion 3132 and vent port 3241, partition 345 being such that dirty liquid communication air entering upper chamber portion 3132 does not flow directly out of vent port 3241, but rather falls into lower chamber portion 3131 and flows out of lower chamber portion 3131, i.e. partition 35 blocks direct communication of upper chamber portion 3132 with vent port 3241, and upper chamber portion 3132 is only in indirect communication with vent port 3241 via lower chamber portion 3131.

As shown in fig. 8, when dirty-liquid air mixture is drawn into dirty-liquid tank 30 from intake pipe 314, the dirty-liquid air mixture first enters primary chamber 312, dirty liquid and a small amount of air will enter secondary chamber 313 from lower opening 3112, and most of the air will escape from notch 3111 into lower chamber 3131 of secondary chamber 313, then from exhaust stub 324 into exhaust 323, and finally escape from outlet 40; at the same time, as the dirty liquid continuously flows into the lower chamber 3131 from the opening 311, as shown in fig. 9, the level of the dirty liquid in the lower chamber 3131 rises gradually until the float (not shown) floats to a predetermined position and blocks the exhaust port 3241 of the exhaust stub 324.

As shown in fig. 10, when a user is working with surface cleaning attachment 100, he or she is likely to tilt dirty liquid tank 30 backwards for ease of operation, and if there is enough dirty liquid in lower chamber portion 3131, he or she will have some of the dirty liquid temporarily flowing into upper chamber portion 3132, which, due to the influence of partition 35, will not flow directly to exhaust port 3141 and thus will not be entrained with the air flowing to exhaust port 3141; this portion of the dirty liquid will flow back into the lower chamber portion 3131 when the dirty liquid tank 30 is upright again or the tilt angle becomes smaller.

The structural design of the upper side chamber part, the lower side chamber part and the partition piece can help the dirty liquid tank to work better, and particularly when the dirty liquid tank works in an inclined or dumping state, dirty liquid cannot flow backwards from the exhaust port as the exhaust short pipe, so that the dirty liquid cannot be sucked into the dust collector which works together after being connected with the surface cleaning accessory, and the dust collector can work in a safe state all the time.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
