Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , the present utility model provides a technical solution: a new type of direct drinking water meter, including a water meter housing 1. Inside the water meter housing 1, a filter 2, a flow guiding cover 20, a hydraulic impeller 21, a display panel 22, a sealing ring 23, a transparent lens 24, and a pressing ring 25 are provided. The hydraulic impeller 21 is rotatably installed inside the flow guiding cover 20. The pressing ring 25 is threadedly connected to the water meter housing 1. By using the pressing force of the pressing ring 25, the flow guiding cover 20, the display panel 22, the sealing ring 23, and the transparent lens 24 are all fixed inside the water meter housing 1. This part is a conventional setting of the prior art and will not be elaborated here.

[0023] One end of the water meter housing 1 is provided with an input pipe 3, and the other end of the water meter housing 1 is provided with an output pipe 4. The surface of the water meter housing 1 is respectively fixedly installed with a first installation pipe 5 and a second installation pipe 6. Plug heads 7 are threadedly installed at the mouths of the first installation pipe 5 and the second installation pipe 6.

[0024] The input pipe 3 communicates with the inner cavity of the water meter housing 1 through the inner cavity of the first installation pipe 5, and the output pipe 4 communicates with the inner cavity of the water meter housing 1 through the inner cavity of the second installation pipe 6. Filter mesh sleeves 8 are placed inside both the first input pipe 3 and the second input pipe 3.

[0025] The filter mesh sleeve 8 is made of stainless steel. An open mouth 19 is formed on the surface of the filter mesh sleeve 8. The filter mesh sleeve 8 can rotate within the first installation pipe 5 or the second installation pipe 6 to adjust the orientation of the open mouth 19. Then, the end of the filter mesh sleeve 8 is pressed tightly by a plug 7, so that the open mouth 19 of the filter mesh sleeve 8 in the first installation pipe 5 faces the input pipe 3 (not shown in the drawings), and the open mouth 19 of the filter mesh sleeve 8 in the second installation pipe 6 faces the inner cavity of the water meter housing 1 (as Figure 2 shown). A control valve 26 is provided inside the output pipe 4.

[0026] Among them, the filter 2 is rotatably arranged inside the inner cavity of the water meter housing 1. A toothed ring 9 is fixedly installed on the surface of the filter 2. A central column 10 is fixedly installed inside the water meter housing 1. A gear 11 is rotatably installed on the surface of the central column 10. A locking nut 12 is threadedly installed at the top of the central column 10. The gear 11 and the toothed ring 9 are in meshing transmission. When a finger extends into the second installation pipe 6, the gear 11 can be rotated, thereby driving the filter 2 to rotate. After the locking nut 12 is tightened, both the gear 11 and the filter 2 are in a fixed state and cannot rotate. For details, see Figure 4 .

[0027] As Figure 2 shown, after the filter mesh sleeve 8 in the first installation pipe 5 is taken out, a cleaning component can be placed inside the first installation pipe 5. Specifically, the cleaning component includes a semi-circular sleeve 13. A sliding plate 14 is slidably installed inside the semi-circular sleeve 13. Brush hairs 15 are arranged on the surface of the sliding plate 14. A flow port 16 is formed on the surface of the semi-circular sleeve 13. A number of water through holes 17 are formed on the surface of the sliding plate 14. When water is injected into the input pipe 3, the water flow can pass through the flow port 16 and the water through holes 17 to wash the surface of the filter 2, realizing washing and flushing simultaneously.

[0028] A rotating block 18 is inserted into the semi-circular sleeve 13. The rotating block 18 pushes the sliding plate 14 to move, so that the brush hairs 15 extend from inside the semi-circular sleeve 13 to the outside of the semi-circular sleeve 13, as Figure 5 shown.

[0029] Working principle: When the direct drinking water meter is connected to the water pipe, the upstream water source is turned off, the plug 7 is removed, and the filter mesh sleeve 8 is taken out. Water can be injected into the first mounting tube 5 to forward flush the filter 2, and water can be injected into the second mounting tube 6 to reverse flush the filter 2. Alternatively, a cleaning component can be installed in the first mounting tube 5, and the semicircular sleeve 13 is inserted into the first mounting tube 5. The rotating block 18 is then inserted into the semicircular sleeve 13, and the bristles 15 are pushed out by the rotating block 18 so that the bristles 15 contact the surface of the filter 2. The rotating block 18 is screwed to drive the semicircular sleeve 13 to rotate, and the bristles 15 swing up and down to clean the surface of the filter 2. At the same time, a finger is inserted into the second mounting tube 6 to drive the filter 2 to rotate by rotating the gear 11. After cleaning, the filter mesh sleeve 8 is installed in the first mounting tube 5 and the second mounting tube 6 respectively, and finally the plug 7 is installed to seal it.

[0030] The novel direct drinking water meter can filter impurities in the water well by arranging a first mounting tube 5 and a second mounting tube 6 on a water meter housing 1 and installing a filter mesh sleeve 8 in the first mounting tube 5 and the second mounting tube 6. By arranging a rotatable filter 2 and installing a cleaning component in the first mounting tube 5, the filter 2 can be rotated while the semicircular sleeve 13 is rotated by the rotating block 18, so that the bristles 15 can swing to clean the attachments on the surface of the filter 2, thereby achieving the effect of cleaning the surface of the filter 2.

[0031] After removing the filter mesh sleeve 8, water can be injected into the water meter housing 1 through the first installation pipe 5 or the second installation pipe 6 to perform forward flushing or backwashing to clear the blockage of the filter 2. Only the plug 7 needs to be removed, and there is no need to remove the internal components of the water meter housing 1, thereby achieving the effect of convenient disassembly and repair.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
