The application relates to the technical field of toothbrush heads and discloses an electric toothbrush head, which comprises a brush body and an insertion block, a lower part of the brush body is provided with an insertion cavity, the insertion block is inserted into the insertion cavity, and the outer side wall of the insertion block abuts against the inner side wall of the insertion cavity; the insertion block is provided with a machine core channel, a vibrating machine core is inserted into the machine core channel and abuts against the inner side wall of the machine core channel; the brush body is provided with a pin shaft which penetrates into the insertion cavity, is inserted into the upper part of the insertion block and fixedly connects the upper part of the insertion block with the brush body; the bottom of the insertion block is formed with a bottom abutting ring which is located below the brush body and abuts against the bottom of the brush body from bottom to top; the vibrating machine core abuts against the inner side wall of the machine core channel, the high-frequency vibration of the vibrating machine core is transmitted to the brush body through the insertion block, and then the bristles on the brush body are driven to vibrate at high frequency; the upper part of the insertion block is fixedly connected with the brush body through the pin shaft, the bottom of the insertion block abuts against the bottom of the brush body from bottom to top through the bottom abutting ring, the installation connection between the insertion block and the brush body is realized, and the structure is stable.

The utility model discloses an aluminum base FFC line row connecting structure, including FFC line row, pressure welding terminal and connector shell, FFC line row includes insulating layer and many flat conductors, and flat conductor has the conductive connecting part of the exposed connection mouth formed in insulating layer, and pressure welding terminal sets up the multiple pressure welding thorn for the puncture FFC line row insulating layer on the pressure welding part, and multiple pressure welding thorn rivet pressure fixed on the conductive connecting part on FFC line row, and the FFC line row of this technical scheme adopts the pressure welding process and realizes the mechanical bite fixed between pressure welding terminal and flat conductor, and the complex link such as medium processing, temperature control of welding is saved, and the process cost and operation difficulty are reduced significantly, and the pressure welding thorn punctures insulating layer through mechanical force and directly forms physical bite with the pressure welding of conductive connecting part, and the connecting strength is much higher than the adhesive force of soldering tin, and it is not easy to come loose, and this multi-point bite structure can disperse vibration impact force, and is suitable for the high frequency vibration working condition of automobile battery.

This invention discloses a high-precision filter device, comprising a housing, a top cover, a filter screen component, and a connector structure. The filter screen component is a hollow cylindrical structure vertically arranged in the accommodating cavity of the housing, forming a closed hollow filter chamber. The connector structure is sealed between the air outlet and the filter screen component, and has an internal ventilation pipe connecting the air outlet and the hollow filter chamber. The gas medium input from the air inlet is filtered by the filter screen component and enters the hollow filter chamber, then undergoes secondary filtration by the filter screen component before entering the ventilation pipe, and finally exits from the air outlet. This ensures that the gas medium can only flow into the connector structure after being filtered by the filter screen component. This filter device has a simple structure, is easy to install and maintain, and helps to increase the contact area between the filter screen component and the gas medium, resulting in high filtration accuracy and improved product performance.

The utility model discloses a flow velocity and liquid level integrated open channel flowmeter, and relates to the technical field of electromagnetic flowmeters. The flow velocity and liquid level integrated open channel flowmeter comprises a flowmeter body, the flowmeter body is provided with an inlet pipe and an outlet pipe, the inlet pipe and the outlet pipe are communicated with the interior of the flowmeter body, the two opposite ends of the inlet pipe and the outlet pipe are both fixedly sleeved with fixing blocks, and the outer surfaces of the two opposite sides of the two fixing blocks are both provided with mounting grooves. According to the flow velocity and liquid level integrated open channel flowmeter, installation and connection between the connecting pipeline and the inlet pipe or the outlet pipe are achieved, installation is convenient and fast, installation and detachment can be completed only by rotating the handle, the installation efficiency is better, installation is more labor-saving, operation is simpler and more convenient, and the flow velocity and liquid level integrated open channel flowmeter is suitable for popularization and application. Therefore, the installation efficiency of the flow meter is improved, and the installation practicability of the flow meter is improved.
