Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] Example 1

[0028] refer to Figures 1-4 A coating brush head for a photovoltaic panel coating liquid includes a support plate 1, a coating component 2 connected to the bottom of the support plate 1, and a liquid supply component 3 connected to the top of the support plate 1. The support plate 1 is provided with multiple liquid outlet pipes 11, and the liquid supply component 3 is provided with an input unit 31 and an output unit 32.

[0029] The input unit 31 is used to connect to the external coating liquid delivery equipment, and the output unit 32 is connected to multiple liquid outlet pipes 11 through the pipe 4, and the coating liquid is delivered to the coating assembly 2 through the liquid outlet pipes 11.

[0030] The coating component 2 can absorb the coating liquid and output the coating liquid during the coating process;

[0031] The support plate 1 is also provided with a connector 12 for connecting the external rod.

[0032] In this design, the operator selects a suitable length of rod according to the required operating distance, and then connects one end of the rod to the connector 12 to form a coating tool for coating photovoltaic panels. In practical use, the operator connects the input unit 31 to an external coating liquid delivery device, which can be a combination of a pump and a storage tank. The pump delivers the coating liquid in the storage tank to the input unit 31, and the input unit 31 outputs the coating liquid from the output unit 32 to the outlet pipe 11 through the liquid supply component 3. The liquid is then delivered to the coating component 2 through the outlet pipe 11. The operator contacts the photovoltaic panel to be coated through the coating component 2 and completes the coating according to the area of ​​the photovoltaic panel.

[0033] It should be noted that the photovoltaic panels should be cleaned and dried before using this coating brush head.

[0034] In this way, multiple liquid outlet pipes 11 are set on the support plate 1, the liquid supply component 3 can be set on the outside for easy maintenance, and the coating liquid can be transported to the coating component 2 located at the bottom of the support plate 1 through the liquid outlet pipes 11, so that most of the area of ​​the coating component 2 participates in the coating, and the utilization rate of the coating component 2 is higher.

[0035] In this embodiment, the liquid supply component 3 is a diverter connected to the top of the support plate 1. The input unit 31 includes an input pipe 311 with two output ends connected to the two ends of the diverter. The output unit 32 includes multiple output ends located on the side of the diverter. The number of output ends matches the number of liquid outlet pipes 11. The output ends are connected to the liquid outlet pipes 11 via pipes 4.

[0036] Specifically, the function of the distributor is to separate the coating solution input into the distributor. More specifically, after the coating solution is input into the distributor, it is distributed to multiple output ends by the distributor. The multiple output ends complete the distribution and output to multiple outlet pipes 11. The purpose of using multiple outlet pipes 11 is to enable the adsorption component to quickly and uniformly adsorb the coating solution.

[0037] Preferably, the connector 12 includes a connecting post 121 and a fixing module 123. The side of the connecting post 121 is provided with a vertically arranged connecting plate 122. The fixing module 123 is connected to the connecting plate 122. The fixing module 123 is used to connect one end of the external rod to the connecting plate 122 in a detachable and rotatable manner.

[0038] In a preferred embodiment, one end of the rod is structurally matched with the connecting post 121 and the connecting plate 122. That is, after one end of the rod is connected to the connecting plate 122 by the fixing module 123, the rod can not only be disassembled but also rotated, which can improve the flexibility of painting and make it easier to cope with more painting environments.

[0039] Furthermore, the fixing module 123 can be a bolt and nut or a cam handle lock. In a preferred embodiment, the fixing module 123 is a cam handle lock, which not only ensures the stability of the connection but also facilitates adjustment. In other embodiments, the fixing module 123 is a bolt, which also ensures the stability of the connection, but the first method is superior in terms of ease of adjustment.

[0040] In this embodiment, the support plate 1 is also provided with an adjustment groove 13 arranged along the length direction of the support plate 1, and the connecting column 121 is slidably connected to the adjustment groove 13.

[0041] Similarly, by providing an adjustment groove 13 on the support plate 1, that is, by changing the fixed position of the connecting column 121 along the length direction of the adjustment groove 13, the relative position of the rod body and the support plate 1 can be changed, thus enabling it to cope with more painting environments.

[0042] Preferably, the side of the connecting post 121 is provided with symmetrically arranged connecting pieces 124. The connecting pieces 124 have an L-shaped structure. The vertical part of the connecting piece 124 is fixedly connected to the side of the connecting post 121, and the horizontal part of the connecting post 121 is connected to the adjusting groove 13. Specifically, the two-point fixing method can ensure the stability of the connecting post 121, and the L-shaped connecting piece 124 can better adapt to the positional relationship between the connecting post 121 and the adjusting groove 13, making the overall appearance more aesthetically pleasing.

[0043] Preferably, the coating assembly 2 includes a fixing block 21 and a sponge 22 connected to the bottom of the fixing block 21. The fixing block 21 is connected to the bottom of the support plate 1 by bolts, and the fixing block 21 is provided with a through hole that matches the liquid outlet pipe 11.

[0044] In practical use, the fixing block 21 mainly serves as a support and does not participate in the adsorption of coating liquid. The sponge 22 can be connected to the bottom of the fixing block 21 by adhesive bonding. In other embodiments, a layer of cotton cloth for brushing can also be wrapped around the sponge 22 by adhesive bonding, which can improve the life of the sponge 22.

[0045] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
