Description

Self-drying water mop with water spray function

Technical field

The utility model relates to a mop, in particular to a self-drying water mop with water spray function.

Background technique

The existing mop-operated mop structure is substantially similar, including a mop rod, a mop tray movably connected to the mop rod, and a water tank disposed on the mop rod and connected to the mop rod to be connected to the water tank The water pump, the water pump is also connected to a nozzle for spraying water outward, the water pump is connected with an operating mechanism for operating the water from the water tank and finally discharging the water from the nozzle; the operating mechanism can be a wrench mechanism, that is, the mop rod The head is provided with a wrench, the wrench abuts an auxiliary pressure bar, the auxiliary pressure bar abuts to penetrate the connecting rod of the mop bar, and the tail of the connecting rod is provided with a pressing mechanism, and the pressing mechanism and the pump plug can interact. By operating the wrench, the pressing mechanism is operated to drive the pump plug to move, and the pump plug has an automatic return device, usually a spring. In the initial state, there is no water in the water pump, the pump plug is pressed down and then rises. The water in the water tank can be sucked into the water pump through the water pump, the pump plug is pressed down again, and the water in the water pump can be sprayed through the nozzle.

For example, the Chinese invention patent "a mop universal water spray device" with the application number CN201410317980.8 (publication number CN104107018A), the Chinese invention patent of the application number CN201510478205.5 (publication number CN104983373A) "a multifunctional water spray Mop, application number CN201610710993.0 (publication number CN106108811A) Chinese invention patent "mops with water and water spray function", they all disclosed a mop that can spray water.

The water spray structure of the existing mop also has the following defects: 1. The water tank and the pump body are independent of the mop rod, and the water tank and the pump body are independently arranged on the mop rod, so that a protruding part is formed on the mop rod to ensure storage. The amount of water, the protruding part of the mop rod will be more obvious, making the entire mop look cumbersome and occupy a large space, which is not conducive to packaging. 2. The flexible water pipe is connected between the water pump and the water tank and between the water pump and the nozzle. It is easy to leak at the joint, affecting the water spray effect, and the assembly is inconvenient.

In the prior art, there is also a self-drying mop, which is provided with a water-repellent handle on the mop rod, and a water-repellent head is arranged at the lower end of the water-handling handle, and the mop head can be inserted into the water-spraying head, so that the relative sliding of the two causes The head of the mop is used to drown the mop head. Because the existing water spray mop has a water tank protruding from the mop rod outside the mop rod, because the water grip handle slides on the mop rod for a long length, the convex water tank will interfere with the water hand grip, which This makes the water handle no longer easy to install on the mop bar.

Summary of the invention

The technical problem to be solved by the utility model is to provide a self-drying water mop with water spray function for the above-mentioned state of the art, the water spray structure of the mop is more reasonable on the mop bar, and the water-repellent function is realized. The perfect combination of water spray function, and the entire mop is small in size while ensuring water storage.

The technical solution adopted by the utility model to solve the above technical problems is: a self-drying water mop with a water spray function, comprising a mop rod, a mop head movably connected at a lower end of the mop rod, and the mop rod is further provided with a top and bottom a sliding water-repellent component, the lower end of the water-repellent component is provided with a water head, the mop head is matched with the water-repellent head and the two are relatively slid and then drowned by the water head; the mop bar is provided with a water spray structure; The water spray structure comprises an inner tube, a water pump and a nozzle, the nozzle is disposed at a lower portion of the mop rod, the inner tube is disposed in the mop rod, and the water pump sprays water in the inner tube through the nozzle through a driving structure When the water is operated, the water-repellent component is located on the outer circumference of the inner tube and slides down relative to the inner tube.

In one embodiment, the mop bar is provided with a water injection port for injecting water into a conventional inner tube. The water pump is disposed in the mop rod and located below the inner tube, and the water pump is connected to the water outlet end of the inner tube, and the water pump is used for It operates to absorb water from the inner tube and ultimately to spray water through the nozzle to drive the drive structure.

As an improvement, the mop bar is provided with a water volume chamber, the opening of the water chamber revealing the top surface of the grip to form the water injection port, and an end cover is provided at the opening of the water chamber, and the water chamber is provided with water.
