Description

A water pump filter device that is easy to clean Technical Field

[0001] The utility model belongs to the technical field of water pump accessories, and in particular relates to a water pump filter device that is easy to clean. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.

[0003] In order to ensure the safety of people's water use and maintain the service life of the water pump, the water requirements for the water pump will be improved to a certain extent. A filtering device will be installed to filter out impurities in the water, thereby protecting the water pump and ensuring that the water delivered to users is purer and healthier. Technical issues

[0004] However, the existing filter device is usually arranged outside the water pump for easy cleaning, which is inconvenient to carry and install. Technical Solutions

[0005] The purpose of the utility model is to provide a water pump filter device that is easy to clean in order to solve the above problems in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions: A water pump filter device that is easy to clean, characterized in that it includes a water pump, the water pump includes a water inlet and a water outlet, the water inlet is threadedly connected to a first ring cover, the water outlet is threadedly connected to a second ring cover, the water pump is provided with a filter chamber connected to the water inlet, the filter chamber is provided with a filter device, the filter device is used to filter the liquid entering from the water inlet, the water inlet is located at the upper end of the filter chamber, the filter device includes a smooth layer, a fixed layer and a filter mesh arranged on the fixed layer, the smooth layer is arranged below the fixed layer, the filter chamber is provided with a drain outlet on the side close to the smooth layer, the drain outlet is used to drain water for cleaning the filter device, and the drain outlet is threadedly connected to a third ring cover.

[0007] The working principle of the utility model is as follows: when the water pump is working normally, unscrew the first and second ring covers, connect the water inlet and the water outlet to the water pipe, the water inlet absorbs water, and the water outlet discharges pressurized water. When the water pump is in normal use, unscrew the first and third ring covers, water flows in from the water inlet, flows downward, and flushes the filter device. Since the second ring cover closes the water outlet, the water used to flush the filter device is discharged from the drain outlet at the lower end of the filter chamber. Since the bottom of the filter device adopts a smooth layer, the particles cannot be adsorbed on the smooth layer, so that the particles are all Leave from the drain outlet, and at the same time, the drain outlet should be designed so that the side of the smooth layer away from the drain outlet is in a high-pressure state, and the liquid and particulate matter will continue to flow to the drain outlet, thereby completing the cleaning of the cleaning device. When the water pump is not in use, the first circle cover, the second circle cover and the third circle cover are not unscrewed to ensure that the water pump is not in an open state to prevent a large amount of dust from accumulating and affecting its use. At the same time, the filter mesh of this application adopts an extended setting to increase the filtering area. After long-term use, the filtering effect can still be guaranteed, reducing the number of times it needs to be replaced or cleaned.

[0008] In the above-mentioned water pump filter device that is easy to clean, the fixed layer includes a plurality of supporting vertical rods and a supporting top seat. The supporting top seat is provided with a through hole for the filter screen to pass through. The supporting top seat is provided with a rotation limit block and two blocking blocks for limiting the vertical movement of the rotation limit block. The rotation limit block is provided with two clearance gaps.

[0009] In the above-mentioned water pump filter device that is easy to clean, a window is provided on the top of the water pump.

[0010] In the above-mentioned water pump filter device that is easy to clean, a fourth ring cover is threadedly connected to the window, and the fourth ring cover is made of a transparent material.

[0011] In the above-mentioned water pump filter device that is easy to clean, the rotation limit block is provided with a threaded hole and a connecting rod threadedly connected to the threaded hole, and the window is provided with a slot for the connecting rod to be inserted and fixed.

[0012] In the above-mentioned water pump filter device that is easy to clean, a step surface is provided inside the fixed layer, and the filter screen is located above the step surface.

[0013] In the above-mentioned water pump filter device that is easy to clean, a plurality of reinforcing ribs are provided inside the smooth layer. Beneficial effects

[0014] Compared with the prior art, the utility model has the advantage that the filtering device is located inside the water pump and is easy to clean. BRIEF DESCRIPTION OF THE DRAWINGS
