[0002] In some areas where shallow well water is used for domestic use, the quality of the well water is affected by surface water or the location of the well, making it impossible to guarantee its quality when used for domestic purposes. To ensure the health of domestic water, we provide a domestic water filter to improve daily domestic water and prevent impurities from entering the home. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a domestic water filter.

[0004] This utility model relates to a domestic water filter, comprising:

[0005] The system includes an inlet pipe and an outlet pipe, with several filter components installed between the inlet pipe and the outlet pipe.

[0006] The filter assembly includes a first connecting pipe and a second connecting pipe that are respectively connected to the inlet pipe and the outlet pipe. At least two mounting pipes are installed in parallel between the first connecting pipe and the second connecting pipe. A filter is installed at the outlet end of the mounting pipe, and an inlet valve is installed at the inlet end of the mounting pipe.

[0007] The installation pipes between several filters and inlet valves are connected to the same drain pipe through drain branch pipes, and each drain branch pipe is equipped with a drain valve.

[0008] In some embodiments, the filter is a pre-filter.

[0009] In some embodiments, both the inlet valve and the drain valve are manual valves.

[0010] In some embodiments, the drain valve is a faucet, and a portion of the faucet's inlet end forms a drain branch pipe;

[0011] In some embodiments, the inlet valve is a ball valve.

[0012] In some embodiments, the inlet valve is a normally open solenoid valve, the drain valve is a normally closed solenoid valve, and the normally open solenoid valve and the normally closed solenoid valve connected on the same mounting pipe form a group and are electrically connected to the same first timer switch. Several first timers are electrically connected to the same second timer switch through a transformer, and the second timer switch is connected to the mains power through a circuit breaker.

[0027] Example 1:

[0028] Please see Figure 1 The domestic water filter of this utility model includes:

[0029] Water inlet pipe 1 and water outlet pipe 2, with several filter components 3 installed between water inlet pipe 1 and water outlet pipe 2;

[0030] The filter assembly 3 includes a first connecting pipe 31 and a second connecting pipe 32 that are respectively connected to the inlet pipe 1 and the outlet pipe 2. At least two mounting pipes 33 are installed in parallel between the first connecting pipe 31 and the second connecting pipe 32. A filter 34 is installed at the outlet end of the mounting pipe 33, and an inlet valve 35 is installed at the inlet end of the mounting pipe 33.

[0031] The mounting pipes 33 between several filters 34 and inlet valves 35 are connected to the same drain pipe 38 through drain branch pipes 36, and each drain branch pipe 36 is equipped with a drain valve 37.

[0032] Filter 34 is a pre-filter 34, and the filtration structure in filter 34 uses a filter screen for filtration; filter 34 can be any device that uses a filter screen for physical filtration.

[0033] Both the inlet valve 35 and the drain valve 37 are manual valves. Manual valves can be ball valves, butterfly valves, or other common valves that can be used for water circuit closure.

[0034] Preferably, the inlet valve 35 is a ball valve. The ball valve can be closed or opened by rotating 90 degrees, and has a clear indication function, thereby ensuring that the inlet valve 35 is in a normal state during operation.

[0035] Preferably, the drain valve 37 is a faucet. When the drain valve 37 is a faucet, the inlet end of the faucet can be directly installed on the installation pipe 33 through a three-way pipe, and the outlet end can be directly connected to the drain pipe 38 to achieve selective connection between the installation pipe 33 and the drain pipe 38. Compared with other butterfly valves or ball valves, there is no need to set up a separate drain branch pipe 36 during installation, which can be installed to effectively ensure the distance between the drain pipe 38 and the installation pipe 33, providing space for operating the faucet.

[0036] Working principle:

[0037] When the device is used for normal filtration, the inlet pipe 1 is connected to the external water source, and the outlet pipe 2 is connected to the user's home.

[0038] When using the device for filtration in daily life, the inlet valve 35 is in the open state and the drain valve 37 is in the closed state. The water source of the inlet pipe 1 will be diverted to multiple installation pipes 33 through the first connecting pipe 31, and then enter the second connecting pipe 32 through the inlet valve 35 and the filter 34. The water flow in the second connecting pipe 32 is filtered by the filter 34 and discharged from the outlet pipe 2, thereby effectively filtering the water source and optimizing the water quality.

[0039] After a period of use, to prevent filter 34 from clogging, it needs to be cleaned. The cleaning method is as follows: First, close the inlet valve 35 on the installation pipe 33, and then open the drain valve 37 on the installation pipe 33 after closing the inlet valve 35. At this time, the water source entering the inlet pipe 1 will enter the installation pipe 33 with the inlet valve 35 open through the first connecting pipe 31, and then enter the second connecting pipe 32 through the corresponding inlet valve 35 and filter 34. The filtered water in the second connecting pipe 32 will enter the installation pipe 33 with the drain valve 37 open, and backwash the filter 34 on the installation pipe 33, thereby effectively removing impurities from the filter end of filter 34, and discharging it through the open drain valve 37 and drain pipe 38; the cleaning method for the remaining filters 34 is the same as above.

[0040] This device can not only effectively optimize water quality, but also effectively and conveniently clean the filter 34, ensuring its performance.

[0041] Example 2:

[0042] The inlet valve 35 is a normally open solenoid valve, and the drain valve 37 is a normally closed solenoid valve. The normally open solenoid valve and the normally closed solenoid valve connected on the same mounting pipe 33 form a group and are electrically connected to the same first timer switch. Several first timers are electrically connected to the same second timer switch through a transformer. The second timer switch is connected to the mains power through a circuit breaker.

[0043] Working principle:

[0044] In daily use, the water flow operation is the same as above;

[0045] When the filter 34 is being cleaned, the second timer switch supplies power to the transformer at a predetermined time. After the current is transformed, the first timer switch is activated in sequence. The sequential activation of the first switches causes the corresponding inlet valve 35 (normally open solenoid valve) in the same group to close and the drain valve 37 (normally closed solenoid valve) to open. Since the corresponding first switches for the other inlet valves 35 and drain valves 37 have not yet been activated, water will flow through the installation pipe 33 of the open inlet valve 35 into the second connecting pipe 32, and then into the installation pipe 33 after the inlet valve 35 is closed to flush the filter 34, and then be discharged from the drain pipe 38. The remaining filters 34 will be automatically cleaned in the same way after the corresponding first switches are activated.

[0046] In this embodiment, the first switch and the second switch can also be manually controlled switches, and the corresponding filter 34 can be automatically cleaned by activating the manual switch.

[0047] In Embodiment 1 and Embodiment 2, there are multiple filters 34 on the same installation pipe 33. The multiple filters 34 are installed sequentially from the water inlet end to the water outlet end, and the arrangement is such that the coarse filter 34 is located in front of the fine filter 34.

[0048] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
