Description

Technical Field

[0001] The invention relates to a water filtering diaphragm air pump, in particular to a water filtering small diaphragm air pump used in an environment requiring clean air. Background Art

[0002] When the diaphragm air pump is working, in order to purify the air, the general treatment method is to place a filter at the air inlet. In the case of high cleanliness requirements for the input air, a filter with very small gaps is required, but it will increase resistance and reduce the air suction efficiency of the air pump. The air pump can also add additional filtering devices to filter the air, but it will increase the equipment structure. The environment with high requirements for air cleanliness requires a simple filtering method. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a water-filtering diaphragm air pump, which can use water to filter air and output clean air without adding an additional pump structure, saving equipment investment, and is suitable for small diaphragm air pumps. The technical solution of the present invention is as follows: A water-filtering diaphragm air pump includes: a base, an air valve, a box body, a filter plate, an upper cover, a pump body, and an electromagnetic motion component. The above-mentioned base is composed of a base box body, a water inlet pipe, a sealing gasket, a cover plate, an air pipe, a pump body support, a clamp, an air outlet pipe, a water tank cover plate, a water outlet pipe, a liquid level meter, and a water tank air pipe.

[0004] Furthermore, the filter sheet is made of filter material and can filter large dust particles in the air.

[0005] Furthermore, the internal space of the base box is divided into four main grids by vertical partitions. An independent grid has a small hole for passing the wire. The other three spaces have small holes on the upper part and are connected together so that gas can pass through. The bottoms of the two grids are connected so that water can pass through. There is a water inlet pipe hole on one side of the water tank, an air outlet pipe hole on the upper part of the other side, a water outlet pipe hole on the bottom, and a liquid level meter hole on the other side.

[0006] Furthermore, the water tank cover has a groove on its edge, which is stuck above the water level of the base water tank, and buffers the flow of water when air enters. There is a gap between one side edge and the box body, and gas can pass through.

[0007] Furthermore, the sealing gasket cooperates with the end surface of the base box and fits the end surface of the vertical plate, so that the box space plays a sealing role.

[0008] Furthermore, the cover plate is fixed to the bottom box body by bolts, has a small hole for installing the pump body support, and has an air pipe hole for connecting the air valve air pipe and the water tank air pipe.

[0009] Furthermore, the water tank air pipe has steps and is fixed on the floor, the upper end of which is connected to the air valve air pipe, the bottom of which goes deep into the bottom of the base water tank, and the end surface is below the water surface.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a water-filtering diaphragm air pump. The air enters the pump body after primary filtration, and the compressed air enters the base water tank, is filtered through water and then enters the air outlet pipe to obtain clean air. The water filtration process is completed in the air pump base without adding additional devices, and the structure is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art are briefly introduced below.

[0012] Figure 1 It is a schematic diagram of the composition structure of the water filtration diaphragm air pump of the present invention.

[0013] In the figure, 1 is the base, 2 is the air valve, 3 is the box, 4 is the filter, 5 is the upper cover, 6 is the pump body, and 7 is the electromagnetic moving part.

[0014] Figure 2 This is a schematic diagram of the base structure.

[0015] In the figure, 1-1 base box, 1-2 water inlet pipe, 1-3 sealing gasket, 1-4 cover plate, 1-5 air pipe, 1-6 pump body support, 1-7 clamp, 1-8 air outlet pipe, 1-9 water tank cover plate, 1-10 water outlet pipe, 1-11 liquid level gauge, 1-12 water tank air pipe Implementation

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Figure 1 As shown, the present invention provides a water filtering diaphragm air pump, which mainly includes a base 1, an air valve 2, a box 3, a filter 4, an upper cover 5, a pump body 6, and an electromagnetic motion component 7. The base 1 mainly includes a base box 1-1, a water inlet pipe 1-2, a sealing gasket 1-3, a cover plate 1-4, an air pipe 1-5, a pump body support 1-6, a clamp 1-7, an air outlet pipe 1-8, a water tank cover plate 1-9, a water outlet pipe 1-10, a liquid level meter 1-11, and a water tank air pipe 1-12.

[0017] When the diaphragm air pump is working, gas enters from the gap between the upper cover 5 and the box body 3, enters the pump body 6 after being filtered by the filter sheet 4, and the electromagnetic moving component 7 drives the air valve 2 to move to inhale air, and then enters the base.

[0018] The base 1 supports the entire pump body. The cover plate 1-4 has small holes, and the pump body support 1-6 made of elastic material is fixed. The pump body 6 is located on the pump body support 1-6, which buffers the vibration generated by the electromagnetic moving part 7 during operation. The cavity in the base 1 also has the effect of silencing and reducing vibration. The base box 1-1, the sealing gasket 1-3 and the cover plate 1-4 form a closed space in the base. The vertical plate in the box body forms a connected closed space for water and air, and a semi-closed space for wires to pass through. The closed cavity of water and air has three parts, and a hole is opened in the upper part of the vertical plate so that the air can be connected. There is no water in one space, which only plays the role of buffering airflow. Two deeper water tank spaces are made separately at the position of the water tank air pipe, and the bottom opening is connected so that water can pass through. In order to buffer the water flow brought by the air, a water tank cover is added to the upper part, and a gap is left on the side so that air can pass through. There is a water inlet pipe on one side of the water tank to fill the water tank, and a water outlet pipe on the bottom of the other side of the water tank to regularly replace the filtered water in the water tank. There is a liquid level gauge on the side between the two water tanks to observe the liquid level in real time to ensure the appropriate water level. There is an air outlet pipe on the upper part of the side of the water tank to exhaust air.

[0019] When the diaphragm air pump is working, air enters the bottom of the water tank from the air valve air pipe 1-5 through the water tank air pipe 1-12, is filtered by water, is mixed into the upper cavity of the base through the side gap of the water tank cover 1-9, and is discharged through the upper air outlet pipe 1-8 to obtain clean air.

[0020] The water-filtering diaphragm air pump provided by the present invention can complete air and water filtration in a base and output clean air without adding an additional air pump structure, and has a simple structure.

[0021] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
