Description

Mop capable of spraying water

Technical Field

The utility model relates to a cleaning tool, in particular to a mop capable of spraying water.

Background

A mop is a long handled cleaning tool for scrubbing the floor. The existing flat mop has a similar structure, and comprises a mop rod and a flat mop head movably connected with the mop rod, wherein the mop head is provided with a wiping material. In order to reduce the packaging and transportation cost, the mop rod is usually provided with 2 to 3 sections, and the 2 to 3 sections of shorter mop rods are connected in sequence to form a longer mop rod. A plurality of common mop poles are fixed through threaded connection, and although this kind of connected mode is comparatively convenient, the screw thread is not hard up easily in the use, and the mop pole is pine easily and takes off, and the influence is used and is experienced. The connection can be realized by a buckle mode, but the fixing reliability of the buckle mode made of plastic materials is low, the buckle is easy to deform and bend, and the mop rod is easy to shake and fall off. In addition, in order to make the flat mop more convenient to use, a mop with a water spraying function appears in the market, the water spraying mop usually further comprises a water tank detachably arranged on a mop rod, a water pump arranged on the mop rod and communicated with the water tank, the water pump is also connected with a nozzle for spraying water outwards, and the water pump is connected with an operating mechanism for operating the water pump to suck water from the water tank and finally spray the water out of the nozzle; the operating mechanism can be a wrench mechanism, namely a wrench is arranged at the head of the mop rod and is abutted against an auxiliary pressure rod, the auxiliary pressure rod is abutted against a connecting rod penetrating into the mop rod, an extrusion mechanism is arranged at the tail of the connecting rod, and the extrusion mechanism and the pump plug can generate interaction. The pump plug is moved by operating the wrench, and thus the squeezing mechanism, and the pump plug has an automatic return device, usually a spring. In the initial state, no water exists in the water outlet pump, the pump plug is pressed down and then rises, water in the water tank can be sucked into the water outlet pump through the water inlet pump, the pump plug is pressed down again, and water in the water outlet pump can be sprayed out through the nozzle. The water tank is required to be arranged outside the lower part or the upper part of the mop rod, so that the overall appearance and size of the mop are influenced, the attractiveness is poor, and the water tank can prevent the mop from being stressed or unbalanced easily, so that the use experience is poor; meanwhile, the spanner realizes water spraying through the operation of the extrusion mechanism by the operation mechanism, and has the advantages of complex structure, more parts, high cost and easy failure. The mop rod is also used for storing water so as to improve the overall aesthetic property of the mop, but the mop rod is usually a stainless steel product, so that the water storage amount is not easy to observe, and the water pump can be added again when the water storage amount is very low and the water pump can not spray water, thereby influencing the use experience. And common mop pole connected mode all has sealed effect poor, can not directly use in the occasion of mop pole storage water, and this just leads to the mop pole all must be whole root when processing, packing, influence processing, packing, cost of transportation.
