[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1 , Figure 2 , Figure 3As shown, an external pressure filter faucet includes a faucet assembly 1, which includes a faucet housing 100. A three-way valve 106 is installed at the middle position of the bottom of the faucet housing 100, and the three-way valve 106 extends to the outside of the faucet housing 100. The three-way valve 106 can change the direction of water flow through its own structural design, so that tap water can enter the interior of the filter assembly 2 or be directly discharged through the interior of the tap water outlet pipe 102. The bottom of the three-way valve 106... A water inlet pipe 107 is installed, extending to the bottom of the faucet housing 100. The inlet pipe 107 allows for the intake and transmission of external tap water. A connecting pipe 101 extending to the outside of the faucet housing 100 is installed on one side of a three-way valve 106. A tap water outlet pipe 102 is rotatably connected to the top of the end of the connecting pipe 101 away from the three-way valve 106. The connecting pipe 101 facilitates the rotatable connection between the tap water outlet pipe 102 and the faucet housing 100. An extension sleeve 105 is installed on the top of the three-way valve 106. The extension design of the extension sleeve 105 facilitates the insertion and connection of the water production pipe 201 later. A faucet end cap 103 is covered on the top of the outer side of the faucet housing 100. The faucet end cap 103 enables the sealing installation of the inside of the faucet housing 100. A sealing ring is provided on the inner side of the faucet end cap 103, and the sealing ring fits against the top of the outer side of the faucet housing 100. A pure water outlet pipe 104 is installed at the middle position of the top of the faucet end cap 103, and the inside of the pure water outlet pipe 104 is connected to the inside of the faucet housing 100. The design of the pure water outlet pipe 104 facilitates the discharge of pure water later. Fixing rods are provided on both sides of the top of the faucet end cap 103, and the bottom of the two sets of fixing rods are jointly installed with the filter end cap 203. The fixing rod design enables the fixed connection of the filter end cap 203 and the above components, and also facilitates the discharge of pure water later.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the faucet end cap 103 has disassembly and assembly components 3 installed on both sides to cooperate with the faucet housing 100. The disassembly and assembly components 3 include fixing slots 300 installed on the top of both sides of the faucet housing 100 and located directly below the faucet end cap 103. Each of the two sets of fixing slots 300 has a guide slope on the side of its top that is far apart. The disassembly and assembly components 3 also include mounting sleeves 302 installed on both sides of the faucet end cap 103. Each of the two sets of mounting sleeves 302 has a connecting rod 303 extending to its outside slidably mounted on the side of its interior that is far apart. Each of the two sets of mounting sleeves 302 has a spring 30 connected to the connecting rod 303 on the side of its interior that is close together. 1. The design of spring 301 enables the connection between connecting sleeve 303 and L-shaped locking rod 304, and also facilitates the subsequent movement and reset of connecting sleeve 303 inside L-shaped locking rod 304. L-shaped locking rod 304 is installed on the side of the two sets of connecting sleeves 303 that are far apart, and the bottom of the side of the two sets of L-shaped locking rod 304 that is close to each other extends into the inside of the fixing slot 300 and engages with it. The bottom side of the two sets of L-shaped locking rod 304 that is close to each other is provided with guide slope 2. Through the cooperative design of guide slope 1 and guide slope 2, the pressing and locking function of faucet end cap 103 and faucet shell 100 can be easily realized later.

[0022] like Figure 2 , Figure 3 As shown, a filter element assembly 2 extending into the faucet housing 100 is installed on the top inner side of the faucet end cap 103. The filter element assembly 2 includes a filter element end cap 203 installed on the top inner side of the faucet end cap 103. An external threaded connecting block 204 is threadedly connected to the inside of the filter element end cap 203. Through the structural design of the filter element end cap 203 and the external threaded connecting block 204, it is convenient to fix and install the filter screen barrel 200 and its components later. Through the fixed connection between the faucet end cap 103 and the filter element end cap 203, and with the external threaded connecting block 204, it is convenient to remove the filter element assembly 2 when the faucet end cap 103 is closed with the faucet housing 100. An extension is installed at the bottom of the external threaded connecting block 204. The filter screen 200 inside the faucet housing 100 allows for the installation and placement of its internal components. A filter element 202 is placed inside the filter screen 200, and its material design enables the filtration of tap water. A water production pipe 201 extending to the outside of the filter screen 200 is installed in the middle of the filter element 202, with its bottom inserted into the extension sleeve 105. A sealing ring 2 is provided at the bottom of the outer side of the water production pipe 201, and this sealing ring 2 is inserted into and sealed to the extension sleeve 105. Through holes 205 are evenly distributed at the top of the outer side of the water production pipe 201, facilitating the subsequent filtration and discharge of water from inside the water production pipe 201.

[0023] It should be noted that, in the case of this type of external pressure filter faucet, the operator can directly connect the external water pipe to the inlet pipe 107. Then, through the structural design of the three-way valve 106, the water source in the external water pipe can be controlled. The three-way valve 106 can be controlled to control the water flow in different directions according to the user's needs. When the three-way valve 106 controls the connection inside the connecting pipe 101, the water in the external water pipe can be discharged through the inlet pipe 107 and the connecting pipe 101 and finally through the tap water outlet pipe 102 to obtain tap water.

[0024] Later, when the three-way valve 106 connects the inlet pipe 107 with the extension sleeve 105, tap water can enter the water production pipe 201 through the extension sleeve 105, and then be discharged into the filter element 202 through the through hole 205, so that the tap water can be filtered and purified through the filter element 202. The filtered tap water can enter the faucet shell 100 through the filter screen 200, and finally be discharged through the pure water outlet pipe 104, thus realizing the pure water output operation.

[0025] When it is necessary to inspect and replace the filter element assembly 2 later, the operator can directly pull the L-shaped lever 304 to move the connecting sleeve 303 inside the mounting sleeve 302, thereby stretching the spring 301. At the same time, the movement of the L-shaped lever 304 allows it to disengage into the fixing slot 300. Then, the faucet end cap 103 and the faucet housing 100 can be released from their locking mechanism. Finally, the filter element assembly 2 can be removed from inside the faucet housing 100 through the faucet end cap 103 for easy inspection and replacement later. After the replacement is completed, the faucet end cap 103 is removed and the filter element assembly 2 is placed inside the faucet housing 100, so that the faucet end cap 103 can close the faucet housing 100. Then, by pressing the faucet end cap 103, the guide slope one and guide slope two at the top of the fixing slot 300 and the bottom of the L-shaped rod 304 can be matched to facilitate the automatic locking function of the faucet end cap 103 and the faucet housing 100 in the later stage, which improves the convenience and flexibility of the later installation and locking.

[0026] After removing the faucet end cap 103, rotating the filter screen barrel 200 causes the external threaded connecting block 204 to rotate inside the filter element end cap 203, thus removing the filter screen barrel 200 and its internal components. This facilitates future maintenance and replacement of the filter screen barrel 200 and its components. Simultaneously, removing the filter screen barrel 200 also allows the water production pipe 201 to be pulled out of the extension sleeve 105, thus disconnecting it from the three-way valve 106. Later, the water production pipe 201 can be reinserted into the extension sleeve 105 to connect with the three-way valve 106.

[0027] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
