The second crimping part is provided with a mounting groove, and the mounting groove is provided with a sealing ring. The upper end of the sealing ring protrudes from the mounting groove and is used to partially squeeze into the sealing groove of the fluid chamber of the booster pump.

[0008] Furthermore, the upper end of the sealing ring has a free portion that is not abutted by the first pressing portion.

[0009] Furthermore, the free portion is used to allow the sealing ribs disposed on the diaphragm in the fluid chamber of the booster pump to be compressed and deformed.

[0010] This utility model also proposes a pump head structure, including a fluid chamber for a booster pump and a bracket. The bottom of the fluid chamber for the booster pump is provided with a first pressing part, and the pressing part is provided with a sealing groove. The top of the bracket is provided with a second pressing part, and the second pressing part is provided with a mounting groove. The mounting groove is provided with a sealing ring, and the upper end of the sealing ring protrudes from the mounting groove. The first pressing part and the second pressing part are pressed together so that the sealing ring is partially squeezed into the sealing groove.

[0011] Furthermore, the sealing groove is arranged continuously around the internal space of the fluid chamber for the booster pump.

[0012] Furthermore, the upper end of the sealing ring has a free portion that is not abutted by the first pressing portion.

[0013] Furthermore, the pump head structure includes a diaphragm disposed in the fluid chamber of the booster pump, the diaphragm having a sealing rib that abuts against the free portion and compresses the free portion to deform.

[0014] This utility model also proposes a booster pump, including a pump head structure. The pump head structure includes a fluid chamber for boosting the pump and a support. The bottom of the fluid chamber for boosting the pump is provided with a first crimping part, and the crimping part is provided with a sealing groove. The top of the support is provided with a second crimping part, and the second crimping part is provided with a mounting groove. The mounting groove is provided with a sealing ring, and the upper end of the sealing ring protrudes from the mounting groove. The first crimping part and the second crimping part are crimped together so that the sealing ring is partially squeezed into the sealing groove.

[0015] According to the above technical solution, the present invention has the following advantages: the fluid chamber of the booster pump is connected to the support by pressing the first pressing part and the second pressing part together. A sealing ring is provided on the second pressing part, so the sealing ring is squeezed by the first pressing part. The first pressing part is provided with a sealing groove, and the sealing ring will be embedded in the sealing groove due to the compression deformation. This results in a better sealing effect and solves the problem of poor sealing effect when pressing the fluid chamber of the booster pump to the support in existing booster pumps.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Example 1

[0023] like Figure 1 and Figure 2 As shown, this utility model embodiment proposes a fluid chamber 11 for a booster pump. The bottom of the fluid chamber 11 for the booster pump is provided with a first crimping part 111 that abuts against the second crimping part 121 of the bracket 12. The first crimping part 111 is provided with a sealing groove 1111 into which the sealing ring 1212 on the bracket 12 is partially squeezed.

[0024] The fluid chamber 11 of the booster pump is connected to the bracket 12 by pressing the first crimping part 111 and the second crimping part 121. A sealing ring 1212 is provided on the second crimping part 121. The sealing ring 1212 is squeezed by the first crimping part 111. The first crimping part 111 is provided with a sealing groove 1111. The sealing ring 1212 will be embedded in the sealing groove 1111 due to the compression deformation. This has a better sealing effect and solves the problem of poor sealing effect of the crimping between the fluid chamber and the bracket in the existing booster pump.

[0025] In this embodiment, the newly added sealing groove 1111 is not used to install and fix the sealing ring 1212, but is used so that the sealing ring 1212 is deformed during crimping and squeezed into the sealing groove 1111.

[0026] Specifically, the shape of the sealing groove 1111 is not limited; it can be rectangular, arc-shaped, or irregular.

[0027] In this embodiment, the sealing groove 1111 includes a first sidewall, a second sidewall, and a bottom wall. The two sides of the bottom wall are respectively connected to the first sidewall and the second sidewall, thereby forming the sealing groove 1111.

[0028] In this embodiment, the width of the sealing groove 1111 is smaller than the width of the sealing ring 1212, so that the sealing ring 1212 can fill the sealing groove 1111 in the width direction, thereby increasing the sealing performance.

[0029] Specifically, the sealing ring 1212 abuts against the first pressing part 111 and is squeezed into the sealing groove 1111, and abuts against the first side wall, the second side wall and the bottom wall respectively.

[0030] In some embodiments, the sealing ring 1212 abuts against the first pressing portion 111 and is squeezed into the sealing groove 1111. The portion squeezed into the sealing groove 1111 abuts against the first sidewall and the second sidewall respectively, but does not contact the bottom wall. This also achieves a good sealing effect. Of course, depending on the irregular distribution of the upper part of the sealing ring 1212, the portion squeezed into the sealing groove 1111 may only abut against the first sidewall or the second sidewall, which can also achieve a sealing effect.

[0031] In this embodiment, the sealing groove 1111 is arranged continuously around the internal space of the fluid chamber 11 for the booster pump. The sealing groove 1111 is arranged around the fluid chamber 11, and the beginning and end of the sealing groove 1111 are connected, so that the portion of the sealing ring 1212 squeezed into the sealing groove 1111 is also uninterrupted, resulting in a better sealing effect.

[0032] Example 2

[0033] This utility model embodiment also proposes a bracket 12, the top of which is provided with a second crimping part 121 that abuts against a first crimping part 111 of the fluid chamber 11 for the booster pump. The second crimping part 121 is provided with a mounting groove 1211, and the mounting groove 1211 is provided with a sealing ring 1212. The upper end of the sealing ring 1212 protrudes from the mounting groove 1211 and is used to partially squeeze into the sealing groove 1111 of the fluid chamber 11 for the booster pump.

[0034] The fluid chamber 11 of the booster pump is connected to the bracket 12 by pressing the first crimping part 111 and the second crimping part 121. A sealing ring 1212 is provided on the second crimping part 121. The sealing ring 1212 is squeezed by the first crimping part 111. The first crimping part 111 is provided with a sealing groove 1111. The sealing ring 1212 will be embedded in the sealing groove 1111 due to the compression deformation. This has a better sealing effect and solves the problem of poor sealing effect of the crimping between the fluid chamber and the bracket in the existing booster pump.

[0035] A mounting groove 1211 is provided on the second crimping part 121. Part of the mounting groove 1211 corresponds vertically to the first crimping part 111. The sealing ring 1212 is installed in the mounting groove 1211. When the first crimping part 111 and the second crimping part 121 are crimped, the sealing ring 1212 protrudes and is partially squeezed by the first crimping part 111. Specifically, the sealing ring 1212 is divided into an outer ring and an inner ring. The outer ring is squeezed by the first crimping part 111 and will be squeezed into the sealing groove 1111.

[0036] In this embodiment, the upper end of the sealing ring 1212 has a free portion 12121 that is not abutted by the first pressing portion 111. According to the above division of the sealing ring 1212, the inner ring portion is the free portion 12121.

[0037] In this embodiment, the free portion 12121 is used to compress and deform the sealing rib 131 disposed on the diaphragm 13 in the fluid chamber 11 of the booster pump. The sealing rib 131 compresses the free portion 12121, causing the free portion 12121 to deform so that the sealing rib 131 is embedded in the free portion 12121.

[0038] Specifically, the sealing rib 131 includes a first sealing sidewall, a second sealing sidewall, and a sealing top wall. The free portion 12121 wraps around the sealing rib 131, meaning that the free portion 12121 abuts against the first sealing sidewall, the second sealing sidewall, and the sealing top wall respectively. This results in a better sealing effect.

[0045] In this embodiment, the width of the sealing groove 1111 is smaller than the width of the sealing ring 1212, so that the sealing ring 1212 can fill the sealing groove 1111 in the width direction, thereby increasing the sealing performance.

[0047] In some embodiments, the sealing ring 1212 abuts against the first pressing portion 111 and is squeezed into the sealing groove 1111. The portion squeezed into the sealing groove 1111 abuts against the first sidewall and the second sidewall respectively, but does not contact the bottom wall. This also achieves a good sealing effect. Of course, depending on the irregular distribution of the upper part of the sealing ring 1212, the portion squeezed into the sealing groove 1111 may only abut against the first sidewall or the second sidewall, which can also achieve a sealing effect.

[0048] In this embodiment, the sealing groove 1111 is arranged continuously around the internal space of the fluid chamber 11 for the booster pump.

[0049] A mounting groove 1211 is provided on the second crimping part 121. Part of the mounting groove 1211 corresponds vertically to the first crimping part 111. The sealing ring 1212 is installed in the mounting groove 1211. When the first crimping part 111 and the second crimping part 121 are crimped, the sealing ring 1212 protrudes and is partially squeezed by the first crimping part 111.

The sealing rib 131 compresses the free portion 12121, causing the free portion 12121 to deform so that the sealing rib 131 is embedded in the free portion 12121.

[0052] Specifically, the sealing rib 131 includes a first sealing sidewall, a second sealing sidewall, and a sealing top wall.
