Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps for oral irrigators, and in particular relates to a high-power water pump for oral irrigators with reduced pressure loss. Background Art

[0002] The one-way valve at the water inlet of the water irrigator pump is at the bottom inner of the diaphragm cover. When the diaphragm pushes the water pump to discharge water, the water can only flow out from the periphery of the diaphragm cover and then rush out from the central gap of the duckbill valve. This causes pressure loss in the water pump and reduces the water pump power. Utility Model Content

[0003] The purpose of the present utility model is to solve the above-mentioned problems and to propose a high-power water pump for a water flosser that reduces pressure loss.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a high-power water pump for a water flosser that reduces pressure loss, which includes a pump body, a straight pipe, a diaphragm cover, a first valve body and a second valve body. The straight pipe is connected to the pump body, and the straight pipe is connected to the diaphragm body on the pump body. The diaphragm cover and the first valve body are both installed in the straight pipe. The diaphragm cover is located between the first valve body and the diaphragm body. An extension pipe connected to the straight pipe is provided on one side of the straight pipe, and the second valve body is provided in the extension pipe.

[0005] As a further description of the above technical solution:

[0006] The extension tube is communicated with the straight tube via a water inlet, and the water inlet is located between the diaphragm upper cover and the diaphragm body.

[0007] As a further description of the above technical solution:

[0008] The second valve body is installed in the extension pipe through a water inlet pipe joint.

[0009] As a further description of the above technical solution:

[0010] A sealing ring is provided between the water inlet pipe joint and the extension pipe.

[0011] As a further description of the above technical solution:

[0012] The first valve body is a duckbill valve, and the second valve body is a one-way valve.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] In the utility model, an extension tube is arranged on one side of the straight tube, and the first valve body is installed in the extension tube. When the pump body drives the diaphragm body to suck the straight tube, under the control of the first valve body and the second valve body, water enters the straight tube from the extension tube and is directly pushed into the diaphragm cover and flushed out, which greatly increases the impact force of the water, reduces pressure loss, and improves the water pump power.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-2 The utility model provides a technical solution: a high-power water pump for a water flosser with reduced pressure loss, comprising a pump body 1, a straight tube 2, a diaphragm cover 3, a first valve body 4, and a second valve body 5. The straight tube 2 is connected to the pump body 1, and the straight tube 2 is connected to the diaphragm body 6 on the pump body 1. The diaphragm cover 3 and the first valve body 4 are both installed in the straight tube 2. The diaphragm cover 3 is located between the first valve body 4 and the diaphragm body 6. An extension tube 7 communicating with the straight tube 2 is provided on one side of the straight tube 2, and the second valve body 5 is provided in the extension tube 7.

[0021] The extension tube 7 is connected to the straight tube 2 via a water inlet 8, and the water inlet 8 is located between the diaphragm upper cover 3 and the diaphragm body 6;

[0022] The second valve body 5 is installed in the extension pipe 7 through the water inlet pipe joint 9;

[0023] A sealing ring 10 is provided between the water inlet pipe joint 9 and the extension pipe 7;

[0024] The first valve body 4 is a duckbill valve, and the second valve body 5 is a one-way valve.

[0025] Working principle: First, the pump body 1 acts on the diaphragm body 6 to pump the main pipe. At this time, the first valve body 4 is in a closed state, the second valve body 5 is open, and the water enters between the diaphragm cover 3 and the diaphragm body 6 from the water inlet pipe joint 9 and the water inlet 8. Secondly, the pump body 1 acts on the diaphragm body 6 to push the main pipe. At this time, the second valve body 5 is closed and the first valve body 4 is opened. The water is directly pushed out from the middle of the diaphragm cover 3, so that the water flow rushing out from the first valve body 4 has a certain pressure. Finally, this cycle is repeated to form a continuous jet.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
