Description

{VACUUM WATER CLEANER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner using vacuum, and more particularly, The present invention relates to a vacuum water cleaner capable of performing clean water irrespective of any part, posture, or place of water, and freeing water to the ceiling as well as the floor, corner, or wall.

As the low fertility continues until recently, it is gradually becoming an aging society. Moreover, the number of patients who can not cover the feces is increasing, but the number of people who can work is gradually decreasing and the caregivers are difficult to obtain. There is a lot of difficulty in doing so.

In addition, in reality, the treatment of the feces of a child who is naturally reluctant to touched by hand other than a kinship, the treatment of the feces of an adult patient causes a tremendous stress to the caregiver.

Therefore, there is an urgent need for an apparatus that can indirectly treat the dirt using tools without directly touching the hands.

As a related art, Korean Patent Laid-Open Publication No. 2001-0068852 proposes a vacuum water cleaner that cleans the object to be cleaned by spraying water, and then sucks and cleans the water mixed with water and dirt. The washing water storage chamber and the waste water recovery chamber are formed as one cylinder and have the same capacity.

As another related technology, Korean Patent Laid-Open Publication No. 2005-0098157 (Patent Document 2) proposes a water cleaning apparatus for a vacuum cleaner in which a water storage tank and a water injection member are formed on a suction member.

However, the vacuum cleaner of the prior art has the following problems.

In the case of Patent Document 1, since the portion for spraying the water and the portion for sucking the sewage water are separated from each other, the cleaning workability is deteriorated and the volume of the vacuum cleaner is increased.

In addition, as in Patent Document 2, when a water bottle is attached to the handle of the vacuum cleaner, it is heavy and bulky to handle the handle, which makes it inconvenient to use the handle. In addition, when the vacuum cleaner is placed on the floor for a while during use, Water can not flow out to the outside.

In addition, most of the vacuum cleaners including patent documents move the vacuum cleaner by dragging the handle hose. In this case, when the main body in which water is stored falls down during use, water is leaked to the outside and sucked into the vacuum motor, Also, even if a child misbehaved by mischief during storage without using a vacuum cleaner, the water inside the vacuum cleaner would flow out to pollute the house.

1. Korean Unexamined Patent Publication No. 2001-0068852 (published on July 23, 2001) 2. KOKAI Publication No. 2005-0098157 (published on October 11, 2005)

In order to solve the problems of the prior art, the present invention can be used regardless of a part of the patient, and water of a predetermined pressure or more can be always sprayed regardless of the direction, angle, and height of the handle, The suction port of the handle and the outlet port of the motor are shut off and the operation of the vacuum motor is stopped to prevent the water of the vacuum cleaner from flowing back toward the handle or the vacuum motor, It is possible to use any part of the patient by allowing the user to check the condition and to have elasticity and elasticity so that the vacuum cleaner can be kept in an airtight state in order to prevent leakage of water even when the vacuum cleaner is inadvertently stored during power- A vacuum water cleaner is provided.

Means for Solving the Problems In order to achieve the above object, the present invention is as follows.

First, a water pump that can supply water to the cleaner body and a water pump with a pressure sensor are attached. When the power of the vacuum cleaner is turned on, the water can be sprayed only while pressing the push button on the handle of the handle. And at the same time a water pump with a pressure sensor is operated so that constant pressure water is always supplied to the water spray nozzle.

Second, the valve switch, which is opened only when the power is applied, is mounted on the suction port and the discharge port. When the vacuum cleaner falls down, the conduction detection sensor senses the power and cuts off the suction port and the discharge port. It prevents the water from flowing to the outside or the motor side. It also keeps the suction port and the discharge port sealed even when moving or storing without moving the cleaner to improve the safety in use or storage.

Third, the suction nozzle of the vacuum cleaner is made of transparent, elastic and stretchable material to prevent irregularities in the outer portion from being excessively vacuumed, and a water outlet for spraying water at the center of the suction nozzle is disposed, and between the edge and the inner wall of the suction nozzle Place a brush to remove hard particles.

According to the present invention, it is possible to use irrespective of a part of a patient, and water above a predetermined pressure can always be sprayed irrespective of the direction, angle, and height of the water injection nozzle, so that the dirt can be cleanly and quickly treated.

In addition, when the vacuum water cleaner is tilted, the operation of the vacuum motor is stopped, and water can be prevented from entering the vacuum motor, thereby preventing the cause of failure and providing excellent durability and easy maintenance

In addition, since the suction nozzle portion is transparent, it is easy to confirm the cleaning process and condition, and it is possible to use any portion of the patient because it has elasticity and stretchability, so that it is easy for the user to clean and does not give the patient any discomfort or discomfort.

Furthermore, it can be used for various purposes such as not only cleaning the patient's dirt, but also freely washing the water to the ceiling as well as the floor, the corner, or the wall.
