Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water meters, in particular to a water meter counter capable of applying a defogging agent. Background Art
[0002] Because the working environment of water meters is relatively humid, fogging is easy to occur on the transparent cover, affecting the normal reading of the water meter. There are two main demisting methods used by water meters on the market. 1. Spraying demisting agent on the inner surface of the transparent cover. Demisting agent is mainly a surfactant. The main disadvantage of this method is that water mist will dilute the surfactant, thus causing the demisting effect to decrease during the continuous fogging and demisting process. 2. Mechanical demisting. The main technical solutions are as follows:
[0003] CN218066621U provides a defoggerable water meter counter. This invention describes a defoggerable water meter counter comprising: a transparent cover, hermetically connected to a base plate; a gear transmission mechanism located between an upper plate and a lower plate; a character wheel box located between the upper plate and the lower plate, a character wheel mounted within the character wheel box, the character wheel connected to the gear transmission mechanism and driven to rotate by the gear transmission mechanism; a dial integral with the upper plate, the dial being provided with a direct-reading character wheel assembly frame corresponding to the character wheel; and a defogger assembly mounted on the inner surface of the transparent cover, corresponding to the position of the direct-reading character wheel assembly frame. This utility model addresses the problem in the prior art of fog being generated within the transparent cover, which affects normal readings. The utility model provides a defogger assembly. When water mist is generated within the transparent cover, the defogger assembly can be driven, i.e., by utilizing magnetic elements for adsorption. By moving the magnetic elements outward, the defogger is driven to move, thereby wiping away the fog directly above the direct-reading character wheel assembly frame and ensuring normal readings.
[0004] CN212442162U provides a water meter counter demisting device. The device comprises a meter body, a counter wheel disposed on the upper surface of the meter body, a plastic transparent window disposed on the meter body, and a guide rail disposed on the inner wall of the plastic transparent window.

A guide rail is welded to the inner surface of the plastic transparent window directly above the counter wheel using an ultrasonic process, and a slider wrapped inside a magnet is mounted on the guide rail. When the water meter is misty, a magnet can be used to attract the slider on the guide rail outside the plastic transparent window of the water meter. The slider slides along the inner surface of the plastic transparent window to remove the mist on the plastic transparent window above the counter wheel.
[0005] The main problem is that each time the reading is performed, the mechanical structure needs to be rotated or driven by a magnetic steel, and it is impossible to keep the counter wheel window in a non-fogging state for a period of time after one rotation. Utility Model Content

[0030] Example 1
[0031] like Figure 1-5 The water meter counter shown here, which can be applied with a defogger, comprises a support plate 1, a first sealing ring 2, a transparent cover 3, a lower clamping plate 4, a gear transmission assembly 5, an upper clamping plate 6, a character wheel 7, a lever 8, a wiper 9, a second sealing ring 10, a screw 11, and a knob 12. The gear transmission assembly 5 and the character wheel 7 are mounted between the upper clamping plate 6 and the lower clamping plate 4. After the upper and lower clamping plates are assembled, they are mounted on the support plate 1.
[0032] The transparent cover 3 is provided with a circular hole for installing a knob 12. The lower end of the knob 12 is provided with an annular groove, and the upper end is provided with a slotted groove. The annular groove is used to install a second sealing ring, and the slotted groove can cooperate with a screwdriver to turn the knob 12.
[0033] The wiper 9 is T-shaped, with one end surface mounted on the lever 8. When the lever 8 swings, it drives the wiper 9 within the track 13 of the transparent cover 3, allowing the wiper 9 to slide on the lever 8. Screws 11 (M2x7 screws are used in this embodiment) secure the lever 8 and knob 12, simultaneously compressing and deforming the second sealing ring 10 to achieve a seal. The wiper 9 is provided with a cavity 16 filled with a defogger. A wiping portion is provided on the wiper 9, communicating with the cavity. The wiping portion can be made of a sponge or thick cloth; in this embodiment, a sponge 17 is used.
[0034] The wiping portion can absorb the defogger and wipe the transparent cover 3 under the drive of the driving mechanism.
[0035] The transparent cover 3 is provided with three grooves 14 evenly distributed around the circumference, and the support plate 1 is provided with three bosses 15 evenly distributed around the circumference. The assembled transparent cover assembly (transparent cover, wiper, lever, knob, second sealing ring) is clamped and installed on the support plate 1 through the grooves 14 and bosses 15, and at the same time, the first sealing ring 2 is compressed and deformed to achieve the sealing function.
[0036] The track of the transparent cover 3 is set just above the character wheel 7 and has an L-shaped structure. When the eraser 9 does not need to work, the eraser 9 stays in the track area next to the character wheel 7 and does not affect the character wheel reading.
[0037] When water mist inside the counter affects the reading, use a flat-head screwdriver to tighten the flat-head slot on the upper end of the knob 12, driving the lever 8 to rotate around the knob 12, and at the same time driving the wiper 9 to wipe the water mist in the track of the transparent cover 3 to achieve the demisting function.
[0038] Example 2
[0039] A magnetic sheet is mounted on the wiper 9, and the lever is rotatably fixed to the inner surface of the transparent cover 3 without penetrating the transparent cover 3. When wiping is required, a magnet is used to attract the magnetic sheet, and the magnet is moved to move the wiper 9 to wipe the transparent cover.
