The filter 10 of the ozone water machine 1 is provided with the driving component 13, and the driving component 13 applies pressure to the water in the first cavity 123A, so that the filtering efficiency is improved, the water outlet quantity of the ozone water machine is large, the water outlet speed is high, and the use by a user is more convenient and quicker.

In this embodiment, the first film mounting tube 123 is a cylindrical tube, the mounting hole is a circular hole, the push pillar 131 is cylindrical, the center of gravity of the center axes of the first film mounting tube 123 and the push pillar 131 is, and the center of the mounting hole is located on the center axis of the first film mounting tube 123.

In this embodiment, a gap is formed between the push rod 131 and the first membrane mounting tube 123 to ensure a filtering area, when the push rod 131 moves towards the upper end cover 121, on one hand, pressure is applied to the water in the first cavity 123A, and on the other hand, the volume of the push rod 131 itself can reduce the accommodating volume in the first cavity 123A, so as to accelerate the filtering of the water. It will be appreciated that the speed of the movement of the push post 131 in the direction close to the upper end cap 121 and the length of the push post 131 extending into the first membrane mounting device 123 are related to the filtration rate of the filter, and the filtration rate can be varied by controlling the speed of the movement of the push post 131 and the length of the push post 131 extending into the first membrane mounting device 123.

In order to ensure that the water in the second membrane mounting tube 124 does not flow through the water in the first membrane mounting tube 123, the volume of the push rod 131 leaving the first membrane mounting tube 124 per unit time is less than or equal to the volume of the water flowing into the first membrane mounting tube 124 per unit time from the water inlet portion 111 in the process of being driven by the air cylinder 132 to move towards the lower end cover 122.

In other embodiments, an annular push pillar may be further installed in the second membrane installation tube 122, and similarly, the annular push pillar may be driven by an air cylinder to reciprocate, so as to apply pressure to the water in the second cavity 122A, thereby improving the filtering capability of the second filtering membrane 126.

In this embodiment, both the first filter membrane 125 and the second filter membrane 126 are reverse osmosis membranes, and the pore size of the first filter membrane 125 is larger than that of the second filter membrane 126.

Optionally, the filter assembly 12 further includes a first protection film 127 sandwiched between the first membrane mounting tube 121 and the first filtering membrane 125, and a second protection film 128 sandwiched between the second membrane mounting tube 122 and the second filtering membrane 126, wherein a through hole portion of the first protection film 127 is aligned with a through hole portion of the first filtering membrane 125, and a through hole aperture of the first protection film 127 is slightly larger than a through hole aperture of the first filtering membrane 125; the through hole portions of the second protective film 128 are aligned with the through hole portions of the second filter film 126 and the through hole aperture of the second protective film 128 is slightly larger than the through hole aperture of the second filter film 126.

Alternatively, the first and second

protective films

127 and 128 have weak adhesiveness on the side close to the first film mounting tube 121 and the adhesiveness value decreases with an increase in temperature.

The first protective film 127 and the second protective film 128 can intercept most of particles in water and have strong compressive strength, so that the service life of the first filtering membrane 125 and the service life of the second filtering membrane 126 are prolonged. Specifically, the adhesive exhibits weak adhesiveness (adhesiveness value is about 400 to 550g/25 mm) at room temperature, and the adhesiveness value decreases with increasing temperature, and decreases to about 1/10, which is about 45g/25mm, at 55 to 100 ℃.

The preparation method of the first protective film 127 and the second protective film 128 is as follows: adding 60-70 parts of melamine formaldehyde resin, 10-20 parts of first polyvinyl alcohol (with the molecular weight of 20000-40000), 7-12 parts of second polyvinyl alcohol (with the molecular weight of 10-12 ten thousand), 5-10 parts of hydrophilic nano titanium dioxide ions, 5-10 parts of nano starch and a proper amount of warm water with the temperature of 50-60 ℃ into a constant-temperature reaction kettle, stirring for 2-3 hours, and performing vacuum defoaming to obtain the protective film material.

The first protective film 127 and the second protective film 128 provided by the present invention decrease with the increase of the temperature due to the viscosity value thereof, and when the filter 10 works, the fine particles in the water are intercepted by the first protective film 127 and the second protective film 128 first, so as to improve the service life of the first filtering membrane 125 and the second filtering membrane 126; in cleaning the filter 10, the filter may be soaked with water having a relatively high temperature, and the viscosity values of the first protective film 127 and the second protective film 128 are lowered, so that the particles caught on the first protective film 127 and the second protective film 128 are dropped off, thereby cleaning the filter 10.

Referring to fig. 2, optionally, the ozonated water machine 1 further includes a data acquisition unit 50, and a cleaning device 70 for cleaning the filter 10, wherein the data acquisition unit 50 and the cleaning device 70 are both connected to the controller 40.

Optionally, the air cylinder 132 is electrically connected to the controller 40, and the controller 40 is further configured to increase a speed at which the air cylinder 132 drives the push pillar 131 to move toward a direction close to the upper end cover 121 when the effluent flow value output by the first flow sensor 51 is less than or equal to 80% of the designed effluent flow value and the detection result of the water quality detector 53 is qualified.

Specifically, the first flow sensor 51 is disposed on a main pipe connecting the water outlet of the filter 10 with the ozone generator and the ozone water mixer, the designed water flow value of the filter is the designed flow of the corresponding filter 10 when the push rod 131 moves toward the lower end cover 122, and the volume of water leaving the first membrane mounting pipe per unit time is equal to the volume of water flowing into the first membrane mounting pipe from the water inlet portion per unit time. The water quality detector 53 is a TDS detection device, and when the TDS value output by the water quality detector 53 is more than 50PPM, the water quality is unqualified; when the TDS value is less than or equal to 50PPM, the water quality is qualified.

As the service life of the ozone water machine 1 is prolonged, the working efficiency of the filter 10 is lower and lower, which in turn causes the gas production of the ozone generator 20 to decrease, and the ozone water concentration and the ozone water yield to decrease. The working efficiency of the filter 10 is judged by monitoring the water outlet flow and the water quality, and when the working efficiency is reduced and the water quality is qualified, the working efficiency of the filter 10 is improved by increasing the speed of the cylinder 132 driving the push column 132 to move towards the direction close to the upper end cover 121; when the working efficiency is reduced and the water quality is unqualified, starting the cleaning device 70; by acquiring data of the using effect (filtering capacity and water quality) of the filter 10, the frequency of the air cylinder is increased or the cleaning device is started, so that the device is more intuitive, more accords with the actual situation and is more relieved for users to use.
