[0029] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0030] like Figure 1-8 As shown, this utility model proposes a booster pump silencer water suction plate, including a water suction plate body 1;

[0031] A first mounting groove 102 is provided in the middle of the front side of the water-absorbing plate body 1, a second mounting groove 109 is provided in the middle of the back side of the water-absorbing plate body 1, and a first positioning hole 101 is provided in the center of the water-absorbing plate body 1, the first positioning hole 101 passing through the first mounting groove 102 and the second mounting groove 109.

[0032] Multiple water storage tanks 106 are provided on the back of the water absorption plate body 1. The multiple water storage tanks 106 are evenly distributed around the second mounting groove 109. Each water storage tank 106 has a set of first water passage holes 103 at the end of its bottom surface near the second mounting groove 109. The first water passage holes 103 are connected to the first mounting groove 102. The set of first water passage holes 103 includes a row of first through holes 103a and a row of second through holes 103b. The diameter of the first through holes 103a is larger than the diameter of the second through holes 103b. Each water storage tank 106 has a second positioning hole 104 and a set of second water passage holes 105 at the end of its bottom surface away from the second mounting groove 109. The second water passage holes 105 are arranged around the second positioning hole 104. Both the second positioning hole 104 and the second water passage holes 105 lead to the front of the water absorption plate body 1, and both the second positioning hole 104 and the second water passage holes 105 are located outside the first mounting groove 102.

[0033] Combination Figure 1 and 2 ,by Figure 1 The viewpoint is from the front of the main body 1 of the water absorption plate. Figure 2 The viewpoint is from the back of the main body 1 of the water absorption plate. According to... Figure 1-4 As can be seen, the horizontal cross-section of the water storage tank 106 is similar to a fan shape, with the first water passage hole 103 and the second water passage hole 105 located at opposite ends within the water storage tank 106. It is easy to understand that a set of first water passage holes 103 includes multiple first water passage holes 103, a row of first through holes 103a includes multiple first through holes 103a, a row of second through holes 103b includes multiple second through holes 103b, and a set of second water passage holes 105 includes multiple second water passage holes 105. For ease of explanation, the following explanation uses the example of the first water passage hole 103 being a drainage hole and the second water passage hole 105 being a suction hole to illustrate the operating principle of the water absorption plate.

[0034] Within each water storage tank 106, the area can be divided into an intake zone and a drainage zone based on the water intake and drainage processes. On the front side of the intake plate body 1, the position of the first mounting groove 102 forms a high-pressure zone with the internal space of the diaphragm booster pump 2, while the position of the second water passage hole 105 on the front side of the intake plate body 1 forms a low-pressure zone with the internal space of the diaphragm booster pump 2. The high-pressure zone and the low-pressure zone are separated. The installation structure of the intake plate body 1 within the diaphragm booster pump 2 is a conventional installation structure, which will not be described in detail here.

[0035] like Figure 6-7 As shown, a first suction cup 201 is provided in the first mounting groove 102. The first suction cup 201 is clearance-fitted or interference-fitted with the first positioning hole 101, and the first suction cup 201 covers multiple sets of first water passage holes 103 on the bottom surface of the first mounting groove 102. That is, the first suction cup 201 can be raised and lowered along the first positioning hole 101. The position of the second positioning hole 104 is connected to the second suction cup 202. The second suction cup 202 is clearance-fitted or interference-fitted with the second positioning hole 104, and the second suction cup 202 covers multiple corresponding second positioning holes 104.

[0036] by Figure 7-8 From a perspective, when the diaphragm in the diaphragm booster pump 2 moves downward, the water in the low-pressure zone of the diaphragm booster pump 2 flows through the second water passage 105, pushes open the second suction cup 202, and enters the water storage tank 106 on the back of the suction plate body 1. Then the diaphragm moves upward. At this time, the water in the water storage tank 106 cannot return to the low-pressure zone through the second water passage 105 due to the obstruction of the second suction cup 202. Instead, it can only push the first suction cup 201 and enter the high-pressure zone. The reciprocating motion of the diaphragm boosts the water in the low-pressure zone and delivers it to the high-pressure zone, and finally outputs it outward.

[0037] It is easy to understand that the first water passage 103 of the present invention can also be connected to the low-pressure area of ​​the diaphragm booster pump 2 as a water suction hole, and the second water passage 105 can also be connected to the high-pressure area of ​​the diaphragm booster pump 2 as a drainage hole. The corresponding suction cup can be installed based on the principle of the diaphragm booster pump 2. This utility model will not be described in detail.

[0038] In this invention, the first water passage 103 is a circular hole structure, which reduces noise during the pressurized water flow process and has a certain noise reduction effect.

[0039] In some embodiments, in each group of first water passage holes 103, a row of second through holes 103b is located between the first positioning hole 101 and a row of first through holes 103a. The size design of each group of first water passage holes 103 can reduce the pulse vibration of the inlet and outlet water pipes, thereby achieving a noise reduction effect.

[0040] like Figure 1-4 As shown, preferably, in each group of first through holes 103, a row of first through holes 103a and a row of second through holes 103b are staggered. More preferably, in each group of first through holes 103, the perpendicular bisector of the center of every two first through holes 103a passes through the center of a second through hole 103b, that is, a second through hole 103b is provided between every two first through holes 103a, which facilitates the rational layout of the positions of the first through holes 103a and the second through holes 103b.

[0041] In some embodiments, the bottom surface of the first mounting groove 102 is an arc surface, and each set of first water passage holes 103 leads to the bottom surface of the first mounting groove 102. Based on the arc surface design of its bottom surface, the depth of the first through hole 103a is greater than the depth of the second through hole 103b. Since the diameter of the first through hole 103a is greater than the diameter of the second through hole 103b, the arc bottom surface of the first mounting groove 102 is conducive to coordinating the water passage effect of the first through hole 103a and the second through hole 103b, reducing pulse vibration, and helping to reduce noise.

[0042] In some embodiments, a recess 107 is provided at one end of the water storage tank 106 near the second mounting groove 109. A first water passage hole 103 is provided in the recess 107 within the water storage tank 106, forming a first water passage cavity within the recess 107. A second water passage cavity is formed in the other areas of the water storage tank 106 excluding the recess 107. The second water passage hole 105 communicates with the second water passage cavity. Figure 8 As can be seen, the first water passage chamber and the second water passage chamber are separated. Taking the second water passage chamber as the water intake chamber and the first water passage chamber as the water discharge chamber as an example, when water is being drawn in, water enters the water intake chamber. When water is being discharged, due to the height difference between the water intake chamber and the water discharge chamber, the water flow is more likely to enter the water discharge chamber and be discharged.

[0043] Preferably, a suction cup mounting position 108 is provided at the end of the water storage tank 106 away from the second mounting groove 109. The bottom surface of the suction cup mounting position 108 is an arc surface. In each water storage tank 106, the second water passage hole 105 and the second positioning hole 104 are both provided in the suction cup mounting position 108, and multiple second water passage holes 105 are arranged around the second positioning hole 104.

[0044] In this invention, the shape of the second water passage 105 is not specifically limited. The second water passage 105 can be an elongated structure, arranged more compactly within the suction cup mounting position 108. Because the water pressure in the low-pressure zone is low, the elongated water passage generates less noise.

[0045] This utility model also proposes a diaphragm booster pump 2, which is equipped with the above-mentioned suction plate, thereby reducing the noise during use.

[0046] The embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the core ideas of this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
