Description

A portable shower with digital display and replaceable filter.

The invention is applicable to the field of bathing.

Rivers and reservoirs are full of various impurities such as pesticides and chemical substances due to the current discharge of industrial wastewater, household wastewater, garbage, agriculture, and animal husbandry. Although purified by the water plant, the water still contains chlorine, chloride and other harmful substances. People purchase water filtration equipment for their own health to filter and drink, and add filters to showers. The principle is to use activated carbon, sulfurous metal, KDF and other absorbent materials to absorb and remove impurities such as chemicals in the water. Such as US 4107046, 6016977, 6270023 and other patents. Although the effect of filtering shower water can be achieved, this filter material has a service life, and the filter effect will be lost after the accumulated amount of filtered water reaches a certain amount. How to grasp the timing of changing the filter has become a difficult problem to grasp.

The object of the present invention is to design a shower, which is characterized in that a handle with a built-in filter and a water wheel are arranged in it to measure the water flow and send a signal of the water flow measurement value, a unit for receiving the signal and a microcomputer The control can prompt the user to replace the filter display warning system.

The purpose of the present invention is achieved like this:

A hand-held shower, which is characterized by a handle with a built-in filter, a built-in water wheel that can measure the cumulative value of water flow and transmit a signal of the measurement result, a unit that receives the signal, and a circuit that is controlled by a microcomputer , Shower heads that can display metering results and forecast user replacement of filters.

Said shower handle is one that can be held in hand, and can be inserted into the seat again, and a shower handle of a filter is arranged inside it.

Said filter is a filter device with built-in activated carbon, sulfurous metal, KDF and other adsorption filter materials that can filter out impurities such as chemical substances and residual pesticides.

The so-called shower head is connected with the shower handle and is divided into two layers with only a small hole in communication. One layer has a small cavity to allow the water wheel to rotate freely and a shower that is full of small holes and can spray water. The head cover, the back of which is a sealed built-in signal receiving unit that does not allow water to enter and a battery-powered metering signal that can convert, accumulate, and control the display screen to display the usage status of the shower. When the filter reaches the end of its service life A circuit system controlled by a microcomputer capable of alarming.

Said water wheel is a built-in shower head that can rotate when water flows in from the small opening between the shower handle and the shower head, and has a counter on it and emits the small impeller of the counting result. The water wheel can be placed in any position of the shower, and this example is placed on the head of the shower.

The computer-controlled circuit is controlled by a battery-powered microcomputer. A receiving unit senses the rotation of the water wheel and is converted into a water flow signal by a data converter. The microcomputer accumulates the data and processes the results in the The water flow is displayed in the digital area, and the filter capacity is displayed in the capacity area. When the service life of the filter is about to end, an alarm bell pattern will appear, and when the service life of the power supply battery is about to end, it will display insufficient capacity.

Positive effect of the present invention:

1. At present, most of the showers do not have a filter. Although some products are equipped with a filter, the service life of the filter element of the filter is given as the cumulative flow in gallons, but it cannot provide measurement, display and early warning. Equipment, so it is difficult for users to accurately grasp the timing of replacing the filter element.

2. Because the amount of water used by each household is different, the service life of the filter element is also different. For example, if a family of three uses 2 gallons of bath water per person per day, the service life of the filter is 250 days, but it can only be used for 125 days in a family of six. Therefore, it is difficult to determine the time when the filter element fails. It is obviously a waste if the filter element is replaced before it fails. If the filter element is still in use after it has failed, the water used is unclean. Harmful impurities containing a large amount of chlorine will produce harmful substances such as trihalomethanes. The trihalomethanes produced by the increase in temperature will increase exponentially during bathing. These harmful substances accumulate in the pores of the human body and will seriously damage the skin. Human health and even cancer. The metering, display and early warning functions of the utility model can accurately remind the user to replace the filter element in time.

Figure 2 is a schematic diagram of the installation of the shower head water wheel, water guide element, and porous plate

Figure 3 is a computer control circuit diagram

The present invention will be further described below in conjunction with the drawings.

In Figure 1, 1 is the screw interface, 2 is the handle of the built-in filter, 3 is the filter, 4 is the water delivery port from the shower handle to the shower head, 5 is the water delivery port from the shower head to the water wheel, and 6 is empty Cavity, 7 is a shower head, 11 is a water wheel with a transmitting unit 8 that can measure the water flow and emit the measurement result with a rotating shaft hole 9, 10 is a receiving unit, 12 is a display panel, and 13 is a water wheel seat 14 is a water guide element that shower head is divided into two layers, 15 is a shower head cover, 18 is a spray hole, and 24, 25, 26, 27, 30 are sealing rings.

16,17 are waterwheel central axis among Fig. 2. Among Fig. 3, 19 is the signal converter that converts the number of rotations of the water wheel into water flow, 20 is powered by battery 23, accumulates the measurement results and sends the results to the display panel 12 and controls the reset key 22, and the restart key 21 microcomputer chips.

Basic principle of the present invention is described further below:

Connect the interface 1, tap water enters the shower handle 2, after being filtered by the filter 3, enters the shower head 7 through the outlet 4, and then enters the cavity 6 through the inlet 5 and drives the water wheel 11 to rotate, and the water wheel 11 rotates once , the transmitting unit 8 on the water wheel just transmits a signal, the signal is received by the receiving unit 10, then sent to the signal converter 19 shown in Figure 3, and then accumulated by the microcomputer 20 powered by the battery 23, and then the measurement result is sent to displayed on the display.

The display is divided into a digital area and a capacity area, the digital area is displayed by four digital tubes, and the capacity area is displayed by a water wheel and 10 long bars. When the filter element is replaced, the zero reset button is activated, and the number area displays "0", and the capacity area is blank. Press the reset button again, and the number area displays the maximum value of the file (3000, 4000, 5000, ... 9000 in total) Galen file), the capacity area shows full grid, (10 small grid bars) and small impeller pattern.

When using this shower, the display of the number area and the capacity area adopts a decreasing method. For example, when the maximum gear is 3000 gallons, the display is every 300 gallons measured, and the capacity area is reduced by one grid, that is, a blank grid. When the metering was decremented to 5 gallons, the alarm bell 29 appeared on the display and constantly flashed until the reset key was restarted.

When the battery capacity is insufficient, the battery 28 pattern is displayed on the display to prompt the user to replace the battery.

When the water drives the water wheel to rotate, the power is automatically turned on, and when the water source is cut off, the power is automatically cut off when the water wheel stops rotating for 10 seconds.
