[0004] However, the following technical problems still exist: the assembly process requires multiple glue application operations, which is relatively complicated and requires precise control of the amount. Excessive glue may cause it to run, affecting the appearance and sealing performance, while insufficient glue may cause it to fail to completely fill the gaps, resulting in sealing failure. Overall, the assembly difficulty and cost are high.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

[0020] This invention effectively avoids the technical problems existing in the prior art, such as the need for multiple glue application operations during assembly, which are relatively complex and require precise control of the glue amount, increasing the difficulty and cost of assembly.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figures 1-4 As shown, this utility model provides a sealing structure for a water pump circuit board 4, including a water pump upper housing 1, a digital display panel 2, a light shield 3, a circuit board 4, a digital display lamp assembly 5, a charging interface 6, and a switch 7. A receiving groove 11 is provided on the top plate of the water pump upper housing 1 for mounting and fixing the digital display panel 2. The water pump upper housing 1 has a receiving cavity 12, and the light shield 3 is snap-fitted into the receiving cavity 12. A through hole 15 is provided corresponding to the position of the charging interface 6 for it to pass through. The circuit board 4 is embedded in the light shield 3. The digital display lamp assembly 5, the charging interface 6, and the switch 7 are electrically connected to the circuit board 4. A notch 32 is provided on the side plate of the light shield 3, and the charging interface 6 is snap-fitted into the notch 32. The switch 7 is sealed to the digital display panel 2 and the light shield 3. A potting space for adhesive to enter is formed between the water pump upper housing 1, the digital display panel 2, the light shield 3, and the switch 7.

[0030] Through integrated design, the water pump upper housing 1, digital display panel 2, light shield 3, circuit board 4, digital display lamp assembly 5, charging interface 6, and switch 7 are tightly combined, reducing the overall size and improving overall stability and reliability. Furthermore, the design of the circuit board 4 embedded within the light shield 3 and the sealed connection between the switch 7 and the digital display panel 2 and light shield 3 creates a potting space for adhesive to enter between the water pump upper housing 1, digital display panel 2, light shield 3, and switch 7. Simply inverting the water pump upper housing 1 allows the adhesive to fully fill the potting space in one go, eliminating the need for multiple adhesive applications, simplifying the assembly process and improving assembly efficiency. Simultaneously, because the adhesive does not flow between the light shield 3 and the circuit board 4, it effectively ensures sealing performance and prevents the adhesive from affecting the digital display lamp assembly 5 and switch 7 on the circuit board 4.

[0031] The adhesive should preferably be a silicone adhesive material with better heat dissipation performance and the ability to adapt to thermal expansion and contraction.

[0032] The charging interface 6 extends to the outside of the water pump upper housing 1 through the notch 32 on the light shield 3 and the through hole 15 on the water pump upper housing 1. It is used to connect to the external power supply and can also play a certain positioning role to ensure a stable connection between the circuit board 4 and the water pump upper housing 1.

[0033] The digital display lamp assembly 5 is used to display parameters such as temperature, remaining battery power, and water output. The light shield 3 is used to block external light and reduce interference from light on the display of the digital display lamp assembly 5, ensuring clear display. The digital display panel 2 allows users to intuitively see the displayed parameters such as temperature, remaining battery power, and water output. The specific circuit connections of the digital display panel 2, switch 7, and circuit board 4 are existing technologies and will not be elaborated upon here.

[0034] After the potting adhesive is applied, the upper housing 1 of the water pump is assembled with the lower housing of the water pump to form a shape as shown. Figure 1 The water pump structure is shown. This invention does not improve the assembly structure of the upper and lower housings of the water pump; the specific connection structure will not be described in detail here.

[0035] As an optional implementation, an adhesive layer is provided on the back panel of the digital display panel 2 and is bonded to the receiving groove 11.

[0036] This design further enhances the stability and sealing of the connection between the digital display panel 2 and the upper housing 1 of the water pump. During potting, the adhesive will not leak out through the gap between the digital display panel 2 and the upper housing 1 of the water pump.

[0037] As an optional implementation, such as Figure 2 , Figure 3 As shown, a guide 13 is provided on the inner wall of the receiving cavity 12, which is adapted to the light shield 3 and is used to guide the light shield 3 into the receiving cavity 12.

[0038] Furthermore, there are multiple guide members 13, which are arranged opposite each other and contact the side plate of the sunshade 3 to guide it correctly into the receiving cavity 12. This arrangement simplifies the installation process of the sunshade 3 and improves assembly efficiency.

[0039] A flow channel is formed between the two guide members 13 located on the same side, through which the adhesive flows into the space between the light shield 3 and the digital display lamp assembly 5. The adhesive can also flow in through the gap between the light shield 3 and the receiving cavity 12, depending on the specific usage requirements.

[0040] As an optional implementation, such as Figure 2 , Figure 3 As shown, a support member 14 is provided on the inner wall of the receiving cavity 12, which is adapted to the light shield 3 and is used to fix the light shield 3 in the receiving cavity 12.

[0041] Furthermore, there are two support members 14, which are positioned opposite each other on the side away from the charging port 6.

[0042] The support member 14, combined with the charging interface 6, provides a stable support force for the sunshade 3, so that the sunshade 3 is securely fixed in the receiving cavity 12.

[0043] As an optional implementation, such as Figure 3 , Figure 4 As shown, the light shield 3 has a first opening 31 for the switch 7 to pass through. The switch 7 is provided with a first sealing ring 71 and a second sealing ring 72. The first sealing ring 71 and the second sealing ring 72 together form a clamping space for clamping the light shield 3. The outer diameter of the first sealing ring 71 and the second sealing ring 72 is larger than the inner diameter of the first opening 31.

[0044] Furthermore, the first sealing ring 71 and the second sealing ring 72 are arranged sequentially along the axial direction of the switch 7. This arrangement improves the sealing and stability of the connection between the switch 7 and the light shield 3, and prevents adhesive from flowing into the interior of the light shield 3 through the first opening 31.

[0045] As an optional implementation, such as Figure 3 , Figure 4 As shown, the digital display panel 2 has a second opening 21 for the switch 7 to pass through. The switch 7 is provided with a third sealing ring 73, which abuts against the digital display panel 2, and the outer diameter of the third sealing ring 73 is larger than the inner diameter of the second opening 21.

[0046] Furthermore, the end of the third sealing ring 73 furthest from the digital display panel 2 is beveled.

[0047] This design improves the sealing and stability of the connection between the switch 7 and the digital display panel 2, preventing glue from flowing out of the digital display panel 2 through the second opening 21.

[0048] As an alternative implementation, the heating element on the circuit board 4 is located on the side away from the switch 7.

[0049] During the potting process, the adhesive will eventually cover the heating element on the circuit board 4, improving the connection stability and reliability between the circuit board 4 and the light shield 3. The adhesive covering layer also improves the heat dissipation efficiency of the heating element, which can quickly dissipate the heat generated by charging and discharging, avoiding the internal expansion and contraction of the switch 7 caused by thermal expansion and contraction, which would result in an unsightly appearance and sealing failure.

[0050] Since the circuit board 4 is embedded in the light shield 3, the glue will not enter between the circuit board 4 and the light shield 3.

[0051] As an optional implementation, such as Figure 1 , Figure 3 As shown, the charging interface 6 is detachably and sealed to the rubber sealing plug 8.

[0052] This design allows the charging port 6 to be sealed with a rubber sealing plug 8 when charging is not needed, providing some protection and preventing the charging port 6 from being exposed to water and rusting over time.
