Description

Technical Field

[0001] The invention relates to the technical field of air suction ports, and in particular to an air suction port protection and air diversion mechanism. Background Art

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors and sucking out sewage at the same time, and taking the sewage away from the site. It has the advantages of environmental protection, energy saving, and high efficiency. Floor scrubbers include semi-automatic floor scrubbers, fully automatic floor scrubbers, hand-push floor scrubbers, and ride-on types. They are generally equipped with a suction motor inside to draw water from the ground into the sewage tank inside the device, thereby achieving the effect of sewage removal.

[0003] However, the existing floor scrubbers mainly adopt a dry-wet separation structure or a float structure for protecting the air suction port of the suction motor. The dry-wet separation structure occupies a large area for installation, is troublesome and inconvenient, has a narrow scope of application, and requires a large number of molded parts for the structure, and requires a water level gauge for auxiliary detection, which is costly. In the float structure, the float end and the fixed end are generally made of rubber, and the connection method is mostly an extrusion connection, which is easy to fall off during use. In addition, during the suction process, the float structure cannot prevent the entry of humid air, which will reduce the service life of the suction motor and increase the failure rate of the machine. Therefore, there is an urgent need for a suction port protection and air diversion mechanism to solve the above problems. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The air inlet protection and air diversion mechanism is provided with a float and a guide sealing ring. This design brings about that by placing a float inside the lower part of the air inlet, when the water level inside the float rises, the float will be driven to float together, so that the float fits tightly with the guide sealing ring, thereby blocking the air inlet connector, so that the air inlet connector cannot discharge the air, and the water level inside the lower part of the air inlet cannot rise.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-7 , an embodiment provided by the present invention: an air inlet protection and air diversion mechanism, comprising an air inlet connector 111, and an air inlet lower portion 112 is arranged on one side of the air inlet connector 111;

[0029] The protection mechanism includes a fixed ring plate 211, one end of the air inlet connector 111 is fixedly connected with the fixed ring plate 211, one side of the fixed ring plate 211 is provided with a fixed ring sleeve 212, and a floating ball 213 is placed inside the lower part 112 of the air inlet. This design facilitates the air inlet connector 111 to be blocked by the floating ball 213, thereby achieving a protective effect;

[0030] A flow dividing mechanism is disposed on one end of the fixed ring plate 211 , and a locking mechanism is disposed on one side of the fixed ring plate 211 .

[0031] The diversion mechanism includes a filter 214, which is engaged on one end of the lower part 112 of the air intake port, and a groove that cooperates with the filter 214 is opened on the lower part 112 of the air intake port. This design makes it easy for air to enter the interior of the air intake port connector 111 only through the filter 214.

[0032] The clamping mechanism includes a positioning rod 311. The positioning rod 311 is fixedly connected to the outer side of one end of the fixed ring plate 211, and a limiting block 313 is fixedly connected to one end of the positioning rod 311, and the limiting block 313 and one end of the positioning rod 311 are tightly fitted to the outer side of the lower part 112 of the air suction port, and the lower part 112 of the air suction port is provided with a limiting groove 312 that cooperates with each other, and one end of the limiting groove 312 is a sliding groove type. This design facilitates the fixed installation of the lower part 112 of the air suction port and the air suction port connector 111.

[0033] The positioning rods 311 are arranged in four groups, and the positioning rods 311 are evenly distributed on the fixed ring plate 211 in a ring shape. This design facilitates more stability during installation.

[0034] A connecting ring 411 is fixedly connected to the middle side of one end of the fixing ring plate 211, and a fixing ring sleeve 212 is sleeved on the outside of the connecting ring 411. Four sets of limiting blocks 412 are fixedly connected to the outside of the connecting ring 411. The limiting blocks 412 all extend into the inside of the fixing ring sleeve 212, and the fixing ring sleeve 212 is provided with limiting grooves 413 that cooperate with each other. This design makes it easy to fix and install the fixing ring sleeve 212.

[0035] A guide seal ring 414 is fixedly connected to one end of the fixed ring sleeve 212 , and the cross section of the guide seal ring 414 is designed to be arc-shaped. This design makes it easy to guide the float 213 through the guide seal ring 414 , which is beneficial for the subsequent abutment between the float 213 and the fixed ring sleeve 212 .

[0036] An oblique groove is provided on the inner side of one end of the fixing ring sleeve 212 , and the fixing ring sleeve 212 can cooperate with the limiting block 412 . This design facilitates smoother engagement.

[0037] The filter 214 is provided with slots which are evenly distributed in a circular shape on the filter 214. This design facilitates the protection of the air inlet connector 111 to prevent the inhalation of foreign matter. The outer end of the filter 214 is provided with an installation groove which cooperates with the positioning rod 311. This design facilitates the further limitation of the filter 214 to make it more stable.

[0038] Working principle: When the device needs to be used, first, the end of the air suction port connector 111 can be installed and connected with the main body of the floor scrubber through bolts, and then the fixing ring sleeve 212 is placed on one side of the connecting ring 411, and then the fixing ring sleeve 212 is pushed toward the side close to the connecting ring 411 to deform the fixing ring sleeve 212, and then the limiting card slot 413 is engaged with the limiting card block 412 to complete the limiting, and then the float 213 is placed inside the lower part 112 of the air suction port, and then the filter screen 214 is placed on the end of the lower part 112 of the air suction port, and the installation slot on the filter screen 214 is aligned with the suction port. The four groups of limiting grooves 312 on the lower part 112 of the air outlet are on the same side, and at the same time, the four groups of limiting grooves 312 are on one side of the limiting block 313. Then, the lower part 112 of the air suction port is pushed toward the side close to the limiting block 313, so that the limiting block 313 abuts against the limiting grooves 312, thereby deforming the positioning rod 311. Then, the pushing is continued so that the limiting block 313 is on one side of the limiting groove 312. At this time, the positioning rod 311 will restore its deformation, so that the limiting block 313 limits the lower part 112 of the air suction port, and the installation can be completed. At the same time, the lower part 112 of the air suction port is inside the sewage tank in the main body of the floor scrubber.

[0039] Subsequently, when the water level inside the sewage tank rises, the buoyancy will drive the float 213 to rise together. When the water level is too high, the float 213 will abut against the guide sealing ring 414, thereby blocking the guide sealing ring 414. When the guide sealing ring 414 is blocked, the air suction port connector 111 will not be able to inhale air normally, so that the water source inside the sewage tank cannot continue to rise, thereby providing protection.

[0040] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
