Problems solved by technology

However, for products using this technology, since there is no external power supply, the control system is powered by a button battery or dry battery with a small capacity, the voltage is low, and the signal is weak, so the control system has weak anti-interference and low reliability. Misreporting the service life of the filter element occurs from time to time

Embodiment 1

[0043] Embodiment one: in conjunction with Fig. 1 and shown in Fig. 2, the special water purifier of driving water dispenser among the present embodiment, comprises water purifier housing (16) and raw water tank (5), the bottom of raw water tank (5) A silk screen (3) and a water outlet pipe (2) are provided, and a water pump (1) is arranged on the water outlet pipe (2). A check valve (9), an active carbon core (12), a softening core (13) and a PP cotton filter element (14) are arranged in the pipeline connecting the water outlet to the pump rear water tank (6), and the bottom of the pump rear water tank (6) is provided with Outlet pipe (15) communicates with the hollow fiber filter element (18) that can filter out bacteria in water, and the water outlet of hollow fiber filter element (18) connects the float valve (19) that can control the water level in the bucket of water dispenser, hollow fiber filter element (18) Be fixed on the water purifier housing (16) by joint (17); De...

Embodiment 2

[0047] Embodiment 2: As shown in Fig. 3 and Fig. 4, the special water purifier for driving water dispenser in this embodiment includes a water purifier housing (30), an intermediate water tank (29) and a raw water tank (28) before the pump , above and below the bottom of the raw water tank (28) are respectively provided with a high-precision double-sided filter microporous ceramic filter element (27) and an active carbon filter element (26), and the middle water tank (29) before the pump is provided with a device that can detect whether there is water therein The probe (25), the bottom of the middle water tank (29) before the pump is provided with a water outlet pipe (24), the water outlet pipe (24) is provided with a water pump (23), and the water outlet of the water pump (2+3) is connected to the upper part of the water purifier. The top of the water tank (31) behind the pump (on the set water level), the bottom of the water tank (31) after the pump is provided with an outlet...

Embodiment 3

[0052] Embodiment three: in conjunction with shown in Fig. 5, the present embodiment is to take further technical measures to embodiment two, specifically, change the indicator light into the display screen (38) that can show the service life information of active carbon core and ceramic filter element, increase The display circuit and the circuit for analyzing and processing the reason for the stop of the water pump. The function of this circuit is: if the water pump stops because there is no water in the middle water tank in front of the pump, no command to start the water pump will be issued within 15 minutes; If the pump stops because there is no water in the water tank in front of the pump, the control system will send a signal that the ceramic filter element is blocked or the original water tank has no water, and the signal will be displayed on the display screen. At the same time, the control system will not send an instruction to start the pump within a period of time. ...

Abstract

A useful time test method and apparatus for a dedicated water purifier filter element of a powered water fountain, and the apparatus comprises a raw water tank, a water pump, a pumped water tank and an electric control breadboard. Wherein, an outlet of the water pump is connected to the pumped water tank, the pumped water tank is provided with a probe for finding the upper set water level and the lower set water level, and then the useful time of the filter element is estimated by testing the operation time of the water pump. The present invention art can judge the service conditions of the dedicated water purifier filter element of the powered water fountain, has relatively high degree of reliability and good anti-interference ability, and can remind a user to clean or change the filter element timely to assure the quality of the outlet water of the purifier of being in accordance with the requirements.

Description

Technical field [0001] The invention relates to the technical field of drinking water purification and control, in particular to a method and device for detecting the service life of a filter element of a special water purifier for a driving water dispenser. Background technique [0002] Water purifiers for drinking fountains have been gradually accepted by consumers because of their many advantages. However, people have also gradually realized that the filter element in the water purifier has a service life. If the service life of the filter element is up, the water purifier will lose the function of purifying water, and a new filter element should be replaced in time. It is generally difficult for ordinary users to judge whether the service life of the filter element has expired, especially for the activated carbon filter element that acts as an adsorbent. [0003] Water purifiers for drinking fountains mainly use two methods of purifying water, filtration and adsorption....
