[0002] Sanitation workers working underground or in windy and dusty weather have a bad environment that has a great impact on their respiratory system. Therefore, it is very important to allow workers to breathe good, pure air in a bad environment. Therefore, it is necessary to design a portable air purification device suitable for underground workers. Such purification equipment should not be too large or too heavy, but should be light, small and simple. Summary of the invention

[0003] In order to design a light, small and convenient air purification device, the present invention provides a portable air purification device.

[0005] The lower waterproof cover comprises a waterproof bottom plate with a central hole, and an air intake side waterproof cover and a water tank side water curtain cover are respectively arranged on both sides of the waterproof bottom plate and located at the central hole, and the air intake side waterproof cover and the water tank side water curtain cover are both trumpet-shaped and the large opening is located on the waterproof bottom plate;

[0006] The water suction motor is installed in the mounting hole of the air intake box bottom plate through the motor fixing block, and the water suction pipe is installed on the water suction motor; the water suction pipe includes a water suction neck pipe and a water distribution pipe connected as one, the water suction neck pipe is a slender pipe, the water distribution pipe is a trumpet-shaped pipe and a drainage hole or drainage groove is provided on the wall plate at the large opening end. The present application utilizes the water suction motor to drive the water suction pipe to rotate, so as to absorb water into the water suction pipe and discharge it from the drainage hole or drainage groove. Under the action of centrifugation, the water is thrown out and hits the water retaining ring, forming a splashing state of water, so as to meet the conditions of the Lenard phenomenon and increase the content of negative oxygen ions in the air that are beneficial to health.

[0007] On the basis of the above technical solution, in order to achieve the convenience of use and the stability of the equipment, the present invention can also make the following improvements to the above technical solution:

[0008] Furthermore, there are three motor fixing blocks, which are evenly arranged on the circumference of the mounting hole of the air intake box bottom plate. The motor fixing blocks have a supporting function, which can ensure that the water suction motor has a gap in the mounting hole of the air intake box bottom plate to ensure that there is enough space for air flow.

[0009] Furthermore, the water retaining ring is inserted into the waterproof cover on the air inlet side with a gap between the two; the end of the water distribution pipe is located in the water retaining ring, and a gap is left between the water suction pipe and the water curtain cover on the water tank side; a sealing plate is provided at the large open end of the water distribution pipe.

[0010] Furthermore, the water suction motor is an outer rotor motor; the water distribution pipe of the water suction pipe is fixed on the water suction motor; ribs are arranged on the inner wall of the water suction pipe, and the ribs are arranged along the axial direction of the water suction pipe.

[0011] Furthermore, the waterproof cover, the water retaining ring and the center hole on the bottom plate of the air intake box are coaxially arranged.

[0012] Furthermore, the side wall of the air intake box is a rectangular structure composed of two long side walls and two short side walls; one of the two long side walls is in an arc-shaped curved surface; and the air intake hole is opened on the long side wall in the arc-shaped curved surface.

[0013] Furthermore, the purified water storage part includes a water box and a protective water tank; the water box is a barrel-shaped structure; the open end of the water box has an internal threaded hole; the protective water tank is cooperatively connected with the lower waterproof cover.

[0014] Furthermore, the pure gas delivery unit includes an upper shell, in which a blower, a battery, a negative ion generator, a control circuit board and control buttons are installed through electrical connection; the probe of the negative ion generator is inserted into the air outlet pipe of the blower; the air outlet of the air outlet pipe of the blower protrudes out of the upper shell, and the control buttons are arranged on the upper shell. The water suction motor is also electrically connected to the control circuit board through a line.

[0015] Furthermore, a belt clamp is provided on the upper shell.

[0016] The advantages of the present invention are: the present invention has a simple structure, and utilizes a motor to drive the water suction pipe to rotate to suck up the water in the water box, and discharge it through the drainage hole or drainage groove on the water distribution pipe. The discharged water will form an umbrella-shaped first layer of water curtain under the action of centrifugation, and will hit the water retaining ring. The water will flow downward along the water retaining ring to form a second layer of water curtain. When air enters through the air inlet hole on the side wall of the air inlet box, it is driven by the fan to flow between the water retaining ring and the waterproof cover on the air inlet side. The air will be purified once in the second layer of water curtain, and then be transported by the fan through the gap between the waterproof cover and the motor, and in the process it will pass through the first layer of water curtain and be further purified. When the first layer of water curtain is formed, the Lenard phenomenon will occur. The Lenard phenomenon was discovered by the German physicist Lenard who won the Nobel Prize in Physics. It means that when water droplets are scattered, negative ions will be generated. The tiny water droplets are positively charged, and the surrounding air will be negatively charged. Therefore, it is named after the discoverer and is called the Lenard phenomenon. When the air is transported by the fan, there is a probe of a negative ion generator in the air duct of the fan that generates negative ions. The air will carry negative ions, which is more beneficial to the human body. Therefore, this application can not only purify the air, but also allow the air to carry negative ions that are beneficial to health. BRIEF DESCRIPTION OF THE DRAWINGS
