Technical Field

[0001] The utility model relates to the technical field of fluid measurement devices, and particularly relates to a single-flow electronic water meter with an anti-magnetic function. Background Art

[0002] A water meter is an instrument for measuring water flow, and is widely used in fields such as water supply, drainage, and industrial production. Most of the existing water meters are single-flow mechanical meters, and a small part are single-flow meters with electronic meter heads. The signal sampling of the single-flow water meter with an electronic meter head lacks electromagnetic shielding, resulting in being easily affected by electromagnetic interference when used in a magnetic field environment, leading to inaccurate counting. Moreover, the existing single-flow water meters with electronic meter heads are all of an integrated structure, that is, the meter head part is fixed relative to the base meter, and the display direction of the display screen on the counter is fixed after installation and cannot be adjusted. When using the manual meter reading method, it is not convenient to read the meter from different angles. Content of the Utility Model

[0003] Based on this, the utility model provides a single-flow electronic water meter with an anti-magnetic function to solve the technical problem that the sampling board of the existing water meter is easily interfered, affecting the sampling accuracy and resulting in inaccurate counting.

It is characterized in that the electronic meter head includes a sampling board, a main board, and an anti-magnetic cover plate. The sampling board is located at the bottom of the electronic meter head and is arranged close to the base meter. The anti-magnetic cover plate is covered above the sampling board. The main board is electrically connected to the sampling board and is arranged above the anti-magnetic cover plate. The main board is connected with a battery and a display screen located at the top of the electronic meter head.

[0005] As a further preferred technical solution of the utility model, the electronic meter head further includes a base and a face cover.

The sampling board and the anti-magnetic cover plate are respectively installed on the base. The face cover is provided with a display window, and the display screen is embedded in the display window.

[0006] As a further preferred technical solution of the utility model, the electronic meter head further includes a housing in the shape of a cylindrical cover body. The lower edge of the housing is connected to the circular end face on the base meter for installing the electronic meter head. The whole formed by connecting the base and the face cover is fixedly arranged in the housing, and at least the area of the housing corresponding to the display screen is made of a transparent material.

[0007] As a further preferred technical solution of the present utility model, the electronic meter head is rotatably arranged on the base meter with the sampling board as the axis of rotation and can rotate 360 degrees.

[0008] As a further preferred technical solution of the present utility model, the lower edge of the outer shell is movably connected to the circular end surface on the base meter for installing the electronic meter head, so that the outer shell can rotate 360 degrees relative to the base meter around its central axis. When the outer shell rotates on the base meter, the whole formed by connecting the base and the face cover is driven to rotate.

[0009] As a further preferred technical solution of the present utility model, a wired communication module and / or a wireless communication module for data communication is provided on the main board.

[0016] The realization of the purpose, functional characteristics and advantages of the present utility model will be further described in conjunction with the embodiments and with reference to the drawings. Specific Embodiments

[0017] The following will further describe the present utility model in conjunction with the accompanying drawings and specific embodiments. Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the preferred embodiments are only for the sake of clarity in narration, rather than to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in technical content, should also be regarded as the scope of implementation of the present utility model.

[0018] As Figure 1 shown, the present utility model provides a single-flow electronic water meter with anti-magnetic function, which includes a base meter 1 and an electronic meter head 2 rotatably installed on the base meter 1 by 360 degrees.

[0019] The electronic meter head 2 includes a housing 27, a base 21, a face cover 26, a sampling board 22, a main board 24, and an anti-magnetic cover board 23. The housing 27 is in the structure of a cylindrical cover body and is made of transparent material. The end face of the base meter 1 for installing the electronic meter head 2 is circular. The lower edge of the housing 27 is movably connected to the circular end face on the base meter 1, so that the housing 27 can rotate 360 degrees relative to the base meter 1 around its central axis; the face cover 26 and the base 21 are connected up and down as a whole and fixed inside the housing 27. The base 21 is close to the circular end face on the base meter 1. The sampling board 22 is arranged close to the base meter 1 and installed at the center of the base 21. The anti-magnetic cover board 23 is covered above the sampling board 22; an installation space is formed by enclosing the face cover 26 and the base 21. The main board 24 and the battery connected to the main board 24 are arranged in this installation space. A display screen 25 is connected to the main board 24. The face cover 26 is provided with a display window, and the display screen 25 is embedded in the display window; the main board 24 is connected to the sampling board 22 through a wiring harness. The main board 24 samples the fluid measurement through the sampling board 22, and the generated counting information is displayed through the display screen 25. It should be noted here that the sampling board 22 is used in cooperation with the base meter 1 for fluid measurement. Usually, an impeller and a magnet are provided in the base meter. When water flows through, the impeller rotates synchronously with the magnet at the top of the impeller shaft. The sampling board uses two magnetoresistive devices. Through a specific angle placement, it can not only collect the rotation of the impeller, but also judge the forward and reverse rotation directions of the impeller to realize the normal measurement of water volume. This belongs to the existing conventional technology, and the detailed structure and principle will not be elaborated here.

[0020] In the present utility model, the anti-magnetic cover board 23 is made of anti-electromagnetic interference material and is covered on the sampling board 22 in a sheet shape, or can also be formed by splicing multiple concentric magnetic rings into a sheet shape. Since the upper part of the sampling board 22 is covered with the anti-magnetic cover board 23, it can prevent the electromagnetic interference of the external environment on the sampling board 22, thereby improving the accuracy of data sampling.

[0021] In the present utility model, since the electronic meter head 2 can rotate 360 degrees relative to the base meter 1, the requirement for the installation environment is not high, which is convenient for observing data through the display screen 25 and is convenient for manual meter reading.

[0022] In a specific embodiment, a wired communication module and a wireless communication module for data communication are provided on the main board 24 to adopt a wired and wireless compatible design. Through the wired communication module, the counting data of the electronic meter head 2 can be transmitted by wired communication. In addition, through the wireless communication module, the counting data of the electronic meter head 2 can be transmitted by wireless communication.

[0023] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that these are only examples, and various changes or modifications can be made to these embodiments without departing from the principle and essence of the present invention. The protection scope of the present invention is only limited by the appended claims.
