Description

TECHNICAL FIELD

[0001] The utility model relates to water purification equipment technical field especially is related to a front filter machine head structure and its front filter. BACKGROUND

[0002] The machine head of the existing front filter adopts full copper material, and the two sides are copper threaded structures, and the PPR connector and the copper head are pressed tightly to form a seal through the copper nut.

[0003] When the existing front filter is installed, the length of the copper head is compared with the existing PPR pipe, and then the existing PPR pipe is cut off, and the PPR connector is hot-melted at the broken part of the PPR pipe, and the PPR connector and the machine head are pressed tightly to form a sealing effect through the copper nut. However, the insertion depth of the PPR connector and the PPR pipe is different during the hot-melting process, which will cause the distance between the two PPR connectors to be different from the distance between the two ends of the copper head. If the distance between the two PPR connectors is too long, the PPR pipes at both ends of the front filter will be stretched after the front filter is installed. If the distance between the two PPR connectors is too short, the PPR pipes at both ends of the front filter will be squeezed after the front filter is installed. Both cases are not good for the PPR pipe. Since the length of a single PPR connector is relatively short, it is easy to twist during hot-melting. After twisting, the seal before the front filter will be poor, which will cause water leakage.

[0004] The existing front filter copper head mainly uses an insert to achieve lead isolation technology. During installation, multiple parts are needed to achieve lead isolation, which requires more manpower during assembly.

[0005] Therefore, it is necessary to solve the problems of complicated process when hot-melting the PPR connectors at both ends of the existing front filter, water leakage caused by improper operation when hot-melting the PPR connectors at both ends, and complicated assembly. UTILITY MODEL CONTENTS

[0006] The utility model aims to solve the above technical problems, and provides a front filter machine head structure and a front filter. During installation, the utility model reduces the action of tightening the nut on one side and pressing it tightly, reduces the process of installing the insert, and makes the assembly of the front filter simpler.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a pre-filter head structure, including a head body, a first pipe and a second pipe provided on the head body, the first pipe having threads, a first PPR pipe connected to the first pipe, a nut on the outside of the threads connecting the first PPR pipe to the first pipe, the second pipe being a heat fusion joint, a second PPR pipe connected to the second pipe, and the second PPR pipe being heat-fused and fixedly connected to the heat fusion joint. Through the above technical solution, the tightening action of tightening the nut on one side is reduced during installation, making the installation process simpler and more convenient; at the same time, the installation process of the inserts is reduced, making assembly simpler.

[0008] Preferably, a silicone gasket is provided between the first PPR pipe and the first conduit, and the silicone gasket is fixed inside the nut. The silicone gasket seals the first PPR pipe and the first conduit, preventing leakage.

[0009] Preferably, the die head body is made of polypropylene. By using the same material for the die head body and the PPR pipe, there are no copper parts, thus avoiding contact between water and copper parts. Since existing die head bodies all have copper parts, which require lead-separating inserts, using polypropylene for the die head body reduces the need for lead-separating inserts, lowers costs, and reduces the number of steps required to install the inserts.

[0010] Preferably, the inner side of the pump head body is provided with a first hole and a second hole, the first hole being connected to a first pipe and the second hole being connected to a second pipe. Through the arrangement of the first and second holes, water can flow into or out of the pump head body.

[0011] Preferably, both the first and second holes are equipped with isolation screens. These screens help filter out large particles of impurities.

[0012] Preferably, the head body also includes a first inner ring and an outer tube, with a groove for securing the filter bottle between the first inner ring and the outer tube.

[0013] Preferably, the first inner ring has a protrusion. The protrusion prevents the filter bottle from sliding out of the groove.

[0014] Preferably, the compressor head body is equipped with a second inner ring component, which divides the compressor head body into an outer ring space and an inner ring space. The first pipe is connected to the outer ring space, and the second pipe is connected to the inner ring space. Through the arrangement of the outer ring space and the inner ring space, the water from the pre-filter enters the filter bottle from the outer ring space, is filtered by the filter components inside the filter bottle, and then flows out from the inner ring space through the second pipe.

[0015] The pre-filter includes the pre-filter head structure and the filter bottle, with the filter bottle connected to the head body.

[0016] The beneficial effects of this utility model are:

[0017] 1. The installation process reduces the need for tightening nuts on one side, making the installation process simpler and more convenient;

[0018] 2. The main body of this utility model uses the same material as PPR pipe, eliminating the need for copper parts, thus avoiding contact between water and copper parts, reducing the installation process of inserts, and making the assembly of the pre-filter simpler.
