Description

Technical Field

[0001] This utility model relates to the field of electrode catalysis technology, specifically to a drip-proof hand-held coating device for catalytic electrodes. Background Technology

[0002] Electrode catalysis refers to the chemical process of promoting or inhibiting electron transfer reactions at an electrode by altering the surface modifiers or modifiers in the solution under the influence of an electric field. Electrode catalysis, also known as electrocatalysis, is an important component of electrochemistry. Its basic principle lies in the fact that, under the influence of an electric field, modifiers present on the electrode surface or in the solution phase can promote or inhibit electron transfer reactions at the electrode. These modifiers themselves do not change during the reaction; rather, the reaction potential or rate is significantly altered by changing the surface modifiers or modifiers in the solution. To improve electrode catalysis efficiency, a handheld coating device is needed. However, existing handheld coating devices still have the following shortcomings:

[0003] When using existing handheld coating devices, the inconvenience of uniformly controlling the amount of coating liquid leads to easy dripping and serious waste, resulting in reduced practicality and efficiency of the handheld coating devices.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a drip-proof hand-held coating device for catalytic electrodes. Utility Model Content

[0005] The purpose of this invention is to provide a drip-proof hand-held coating device for catalytic electrodes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drip-proof handheld coating device for catalytic electrodes, comprising a liquid collection mounting frame and a metering component. The liquid collection mounting frame has a liquid outlet at its lower end, and a metering component is provided at the middle of its upper end. The metering component includes a handle, an anti-slip groove, a control switch, a control valve, a metering pump, and a liquid guide tube. The handle has anti-slip grooves on both sides inside, and a control switch is provided at the upper end of the handle. A control valve is installed at the upper end of the handle, and a metering pump is installed at the upper end of the control valve. A liquid guide tube is connected to the middle of the upper end of the metering pump, and a mounting component is provided at the lower end of the liquid collection mounting frame.

[0007] Furthermore, the handle and the liquid collection mounting bracket are arranged perpendicularly, and the handle and the liquid collection mounting bracket are fixedly connected by bolts.

[0008] Furthermore, the number of anti-slip grooves is set to eight, and four anti-slip grooves are grouped together, with each group of anti-slip grooves symmetrically arranged on both sides of the inside of the handle.

[0009] Furthermore, the control valve is horizontally distributed on the outside of the metering pump, and the control valve is fixedly connected to the metering pump by bolts.

[0010] Furthermore, the installation assembly includes a limiting cylinder, a limiting rod, and a return spring. The limiting cylinder is connected to the limiting rod, and the limiting rod is provided inside the limiting cylinder.

[0011] Furthermore, the mounting assembly also includes a liquid collection chamber, a liquid inlet, a mounting through hole, and a brush. The liquid collection mounting frame has a liquid collection chamber inside, with a liquid inlet at the upper end of the liquid collection chamber and mounting through holes on both sides of the liquid collection chamber. A brush is also provided at the lower end of the liquid collection chamber.

[0012] Furthermore, the limiting rod and the limiting cylinder are embedded in each other, and the limiting rod is elastically connected to the limiting cylinder through a return spring.

[0013] Furthermore, the external dimensions of the limiting rod are adapted to the internal dimensions of the mounting through hole, and the limiting rod is connected to the liquid collection cavity through the mounting through hole.

[0014] This invention provides a drip-proof handheld coating device for catalytic electrodes, which has the following advantages:

[0015] 1.

The metering pump is also fixedly installed on the upper end of the control valve with the fastening bolts. The metering pump works in conjunction with the liquid guide tube to deliver the coating liquid. At the same time, the control valve is used to regulate the output of the coating liquid. After holding the handle, the anti-slip groove increases the friction during the holding process. At the same time, the fingers can easily press the control switch to regulate the operation of the metering pump. Thus, the material can be dispensed according to the needs of use during the use process, avoiding dripping and waste of the coating liquid, and improving the overall practicality and efficiency of the coating device.

Simultaneously, a return spring is used to elastically connect the limiting rod and the limiting cylinder, allowing the liquid collection chamber to be installed inside the liquid collection mounting frame. The limiting rod, in conjunction with the installation through hole, limits the liquid collection chamber to the lower end of the liquid collection mounting frame. The outlet and inlet are aligned, allowing the coating liquid to enter the liquid collection chamber through the inlet and be evenly output from the base of the brush. This increases the ease of brush installation and improves the efficiency of the handheld coating device. Attached Figure Description

A control valve 304 is also installed at the upper end of the handle 301. Simultaneously, a metering pump 305 is installed on the upper end of the control valve 304. A liquid guide tube 306 is connected to the middle of the upper end of the metering pump 305. The handle 301 and the liquid collection mounting bracket 1 are arranged vertically and are fixedly connected by bolts. Eight anti-slip grooves 302 are provided, with four anti-slip grooves 302 forming a group. Each group of anti-slip grooves 302 is symmetrically arranged on both sides inside the handle 301. The outer side of the control valve 304 and the outer side of the metering pump 305 are arranged horizontally, and the control valve 304 is fixedly connected to the metering pump 305 by bolts.

[0024] The specific operation is as follows: The control valve 304 is fixedly installed on the upper end of the handle 301 by fastening bolts, and the metering pump 305 is fixedly installed on the upper end of the control valve 304 in conjunction with the fastening bolts. The metering pump 305 works in conjunction with the liquid guide tube 306 to transport the coating liquid. At the same time, the output of the coating liquid is regulated by the control valve 304. After holding the handle 301, the anti-slip groove 302 increases the friction during the holding process. At the same time, the fingers can easily press the control switch 303 to regulate the operation of the metering pump 305. Thus, the material can be fed according to the needs of use during the use process, avoiding the dripping and waste of the coating liquid, and improving the overall practicality and efficiency of the coating device.

[0025] Example 2

[0026] like Figures 1 to 3 As shown, the lower end of the liquid collection mounting frame 1 is provided with a mounting assembly 4. The mounting assembly 4 includes a limiting cylinder 401, a limiting rod 402, and a return spring 403. The limiting cylinder 401 is internally connected to the limiting rod 402, and the limiting rod 402 is externally located inside the limiting cylinder 401. The mounting assembly 4 also includes a liquid collection chamber 404, a liquid inlet 405, a mounting through hole 406, and a brush 407. The liquid collection mounting frame 1 is internally provided with a liquid collection chamber 404, and the liquid collection chamber 404 contains... The upper end of the part has a liquid inlet 405, and the inside of the liquid collecting cavity 404 has mounting through holes 406 on both sides. At the same time, a brush 407 is provided at the lower end of the liquid collecting cavity 404. The limiting rod 402 is embeddedly connected to the limiting cylinder 401, and the limiting rod 402 is elastically connected to the limiting cylinder 401 through a return spring 403. The external dimensions of the limiting rod 402 are adapted to the internal dimensions of the mounting through holes 406, and the limiting rod 402 is connected to the liquid collecting cavity 404 through the mounting through holes 406.

[0027] The specific operation is as follows: The limiting cylinder 401 is fixedly installed on both sides of the outside of the liquid collection mounting frame 1 by fastening bolts, and the limiting rod 402 is installed inside the limiting cylinder 401. At the same time, the limiting rod 402 and the limiting cylinder 401 are elastically connected by the return spring 403.

The internal dimensions of the mounting through holes 406 opened on both sides of the liquid collection chamber 404 match the external dimensions of the limiting rod 402. Thus, the liquid collection chamber 404 is limited and installed inside the liquid collection mounting frame 1 by the limiting rod 402 and the mounting through holes 406. At the same time, the liquid outlet 2 is connected to the liquid inlet 405, so that the coating liquid enters the liquid collection chamber 404 through the liquid inlet 405 and is evenly output from the root of the brush 407, thereby increasing the ease of installation of the brush 407 and improving the efficiency of the handheld coating device.

Simultaneously, the return spring 403 elastically connects the limiting rod 402 and the limiting cylinder 401. Then, install the liquid collection chamber 404 inside the liquid collection mounting frame 1. The limiting rod 402, in conjunction with the mounting through hole 406, limits the liquid collection chamber 404 to its lower end inside the liquid collection mounting frame 1. Next, fix the control valve 304 to the upper end of the handle 301 using fastening bolts, and then fix the metering pump 305 to the control valve 304 using the fastening bolts.
