Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to an intelligent sterilization water purification equipment. Background Art

[0002] Tap water refers to drinking water that meets supply standards after being processed, purified and disinfected by a water plant. However, during the delivery of tap water, impurities such as rust, bacteria, and algae due to aging pipes will cause secondary pollution to the tap water. Nowadays, with the improvement of people's living standards, people's requirements for the quality of drinking water are getting higher and higher. Many families install water purification equipment on their tap water pipes to purify and sterilize tap water.

[0003] The structure of the existing water purification equipment is a filter for drinking water disclosed in Chinese Patent Publication No. CN114455736A, which includes a shell, a base and a filter element. The base is rotatably mounted on the bottom of the shell, and a water inlet and a water purification port are arranged on the shell. The filter element is mounted on the base. A water purification chamber is arranged inside the shell, and the two ends of the water purification chamber are respectively connected with the water purification port and the filter element. A filter disk is sleeved around the connection between the water purification chamber and the filter element, so that the drinking water entering from the water inlet is filtered through the filter disk and the filter element in turn before entering the water purification chamber. The structure is simple, and impurities such as rust, bacteria, and algae in tap water can be effectively filtered out, and the sterilization and purification effect is good.

[0004] During use, the filter element needs to be replaced regularly, usually every six months to one year, depending on the actual contamination of the filter element. However, in actual use, many users often forget to replace the filter element, and most users do not know when to replace the filter element. Another situation is that in actual use, if the user does not use water for a long time (more than 3 days), the residual water in the filter and water pipe will also breed bacteria, causing the water to have an odor and become unsuitable for drinking. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned problems, the utility model proposes an intelligent sterilization and water purification device, which can intelligently monitor whether the filter is blocked and can intelligently remind the user to maintain the filter.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An intelligent sterilization and water purification device comprises a filter, a water inlet pipe and a water outlet pipe, the filter has a water inlet and a water purification port, the water inlet is connected to the water inlet pipe, the water purification port is connected to the water outlet pipe, and further comprises:

[0008] A first water pressure sensor installed on the water inlet pipe for detecting the water pressure in the water inlet pipe;

[0009] A second water pressure sensor installed on the water outlet pipe for detecting the water pressure in the water outlet pipe;

[0010] A flow sensor installed on the water outlet pipe for detecting the water flow in the water outlet pipe;

[0011] and a controller;

[0012] The controller comprises a housing, a speaker arranged on the surface of the housing, and a PCB circuit board arranged in the housing; the PCB circuit board is integrated with a battery, a microprocessor and a timer circuit;

[0013] The power supply end of the battery is electrically connected to the power supply end of the microprocessor, the timer circuit is electrically connected to the microprocessor, and the first water pressure sensor, the second water pressure sensor, the flow sensor and the speaker are electrically connected to the microprocessor through different wires respectively.

[0014] Furthermore, it also includes a display screen arranged on the surface of the shell; the display screen is electrically connected to the microprocessor through different wires.

[0015] Furthermore, a power detection circuit is integrated on the PCB circuit board;

[0016] The power detection circuit is electrically connected to the power supply terminal of the battery, and the power detection circuit is electrically connected to the microprocessor.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] After long-term use, the filter's internal filter element will become clogged and need to be replaced. When this intelligent sterilization water purification device is in use, when the user uses water, water flows through the outlet pipe, and the water flow sensor detects the size of the water flow to control the microprocessor. At the same time, the tap water pressure in the water inlet pipe is detected by the first water pressure sensor, and the water pressure of the clean water in the outlet pipe that has been purified by the filter is detected by the second water pressure sensor. The controller determines whether the filter element inside the filter is clogged by comparing the pressure difference between the tap water pressure and the clean water pressure. If the pressure difference exceeds the preset value, the microprocessor controls the speaker to issue a sound prompt to remind the user to maintain the filter (specifically replace the filter element).

[0019] In addition, the controller determines the water flow size after each water use (water flow stops in the water pipe), and the timer circuit starts timing. If the user does not use water for a set time (such as 3 days), the microprocessor will control the speaker to sound a reminder the next time the user uses water (water flows through the water purification pipe, and the water flow sensor detects the water flow size), reminding the user to drain some of the water. The amount of water to be drained can be preset in advance, and the amount of water drained can be detected by the water flow sensor. When the actual amount of water drained reaches the preset amount of water to be drained, the speaker stops sounding. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0024] refer to Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides an intelligent sterilization water purification device, including a filter 100, a water inlet pipe 200 and a water outlet pipe 300. The filter 100 is an existing device, and the utility model does not involve the structural improvement of the filter 100 itself. For example, a filter for drinking water disclosed in Chinese Patent Publication No. CN114455736A is adopted, including a housing, a base and a filter element, the base is rotatably mounted on the bottom of the housing, a water inlet and a water purification port are arranged on the housing, the filter element is mounted on the base, a water purification chamber is arranged inside the housing, and the two ends of the water purification chamber are respectively connected to the water purification port and the filter element, and a filter disc is sleeved around the connection point between the water purification chamber and the filter element, so that the drinking water entering from the water inlet is filtered through the filter disc and the filter element in turn before entering the water purification chamber. The filter structure is a prior art and will not be described in detail here.

[0025] The water inlet 101 is connected to the water inlet pipe 200, which is connected to a water pipe (not shown in the figure) when in use. The water purification port 102 is connected to the water outlet pipe 300, which is connected to a faucet (not shown in the figure) when in use.

[0026] It also includes a first water pressure sensor 1, a second water pressure sensor 2, a water flow sensor 3, and a controller 4. The location where the controller 4 is installed does not affect the normal use of the intelligent sterilization water purification device, and the controller 4 is generally installed nearby.

[0027] The first water pressure sensor 1 is installed on the water inlet pipe 200 , and is used to detect the water pressure of the tap water in the water inlet pipe 200 and transmit it to the controller 4 .

[0028] The second water pressure sensor 2 is installed on the water outlet pipe 300 , and is used to detect the water pressure of the clean water in the water outlet pipe 300 that has been purified by the filter 100 and transmit it to the controller 4 .

[0029] The flow sensor 3 is installed on the water outlet pipe 300 , and is used to detect the water flow in the water outlet pipe 300 and transmit the water flow to the controller 4 .

[0030] The controller 4 includes a housing 40, a display screen 41 and a speaker 42 are arranged on the surface of the housing 40, and a PCB circuit board is arranged in the housing 40 (not shown in the figure, but those skilled in the art should understand the implementation method of the PCB circuit board arranged in the housing 40). The PCB circuit board integrates a microprocessor 43, a battery 44, a power detection circuit 45 and a timer circuit 46.

[0031] In this specific embodiment, preferably, the microprocessor 43 adopts an AT89S52 single-chip microcomputer.

[0032] It should be noted that those skilled in the art should have the conventional selection capabilities of the above-mentioned electronic components and circuit connection technical means. Those skilled in the art can fully reproduce the intelligent sterilization and water purification equipment disclosed in this patent application and produce the same technical effect after a limited number of circuit connection experiments based on this specification and the drawings of the specification.

[0033] The circuit connection between the above electronic components is as follows:

[0034] The power terminal of the battery 44 is electrically connected to the power terminal of the microprocessor 43 to provide power to the microprocessor 43 .

[0035] The power detection circuit 45 is electrically connected to the power supply terminal of the battery 44 to detect the power of the battery 44. The power detection circuit 45 is electrically connected to the microprocessor 43 to transmit the detected power of the battery 44 to the microprocessor 43. If the battery 44 is detected to be insufficient, the microprocessor 43 controls the speaker 42 to issue a sound prompt to prompt the battery 44 to be replaced.

[0036] The timer circuit 46 is electrically connected to the microprocessor 43 .

[0037] The first water pressure sensor 1 , the second water pressure sensor 2 , the flow sensor 3 , the display screen 41 and the speaker 42 are electrically connected to the microprocessor 43 through different wires (not shown in the figure).

[0038] During use, when the user uses water, water flows through the water outlet pipe 300, and the water flow sensor 3 detects the size of the water flow to control the microprocessor 43. At the same time, the tap water pressure of the tap water in the water inlet pipe 200 is detected by the first water pressure sensor 1, and the water pressure of the clean water in the water outlet pipe 300 that has been purified by the filter 100 is detected by the second water pressure sensor 2. The microprocessor 43 determines whether the filter element (not shown in the figure) inside the filter 100 is blocked by comparing the pressure difference between the tap water pressure and the clean water pressure. If the pressure difference exceeds the preset value, the microprocessor 43 controls the speaker 42 to issue a sound prompt to prompt the user to maintain the filter 100 (specifically, replace the filter element).

[0039] The microprocessor 43 determines that after each water use (water flow stops in the water pipe 300), the timer circuit 46 starts timing. If the user's water use is not detected for a set time (such as 3 days), the microprocessor 43 will control the speaker 42 to issue a sound prompt the next time the user uses water (water flows in the water purification pipe 300, and the water flow sensor 3 detects the water flow size), reminding the user to drain some of the water. The amount of water to be drained can be preset in advance, and the amount of water drained can be detected by the water flow sensor 3. When the actual amount of water drained reaches the preset amount of water to be drained, the speaker 42 stops issuing the sound prompt.

[0040] This intelligent sterilization and water purification equipment can intelligently monitor whether the filter is blocked and can intelligently remind the user to maintain the filter, and has good practicality.

[0041] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
