Description

Technical Field

[0001] This utility model relates to the field of cleaning tools or cleaning equipment, and more specifically, to a novel suction cup. Background Technology

[0002] Cleaning vacuums can quickly remove water from the ground, and therefore are now widely used in people's daily lives.

[0003] However, as people have used them more extensively, they have discovered that although the suction cups currently on the market also have air duct guide grooves inside, the air duct guide grooves are concave at the connection point with the suction cup tube. This causes the suction force to be unconcentrated when sucking water, which makes it easy for water to accumulate in the concave area, slows down the water flow rate, and causes a small amount of water to flow back due to the unconcentrated suction force.

[0004] Therefore, it is necessary to propose a new type of suction and squeegee to solve the above problems. Utility Model Content

[0005] This invention provides a novel suction cup to overcome at least one of the defects (deficiencies) of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A novel suction cup includes a suction cup front cover and a suction cup rear cover disposed on the suction cup front cover. The suction cup rear cover is provided with a suction cup tube interface, and the suction cup front cover is provided with an air duct guide groove that communicates with the suction cup tube interface.

[0007] The connection between the air duct guide groove and the suction pipe interface protrudes outward, causing the connection between the air duct guide groove and the suction pipe interface to narrow rapidly into a funnel shape. By setting the connection between the air duct guide groove and the suction pipe interface to protrude outward and to narrow rapidly into a funnel shape, the suction force can be more concentrated, while avoiding the situation where water can easily accumulate in the concave area and cause the water flow rate to slow down.

[0008] Furthermore, the included angle of the air duct guide groove at the narrowest point on both sides of the suction pipe interface is 90-120 degrees. Due to the outward protrusion of the connection between the air duct guide groove and the suction pipe interface, the included angle of the air duct guide groove at the narrowest point on both sides of the suction pipe interface is 90-120 degrees. This can prevent water from accumulating in the concave area and also prevent the water flow rate from slowing down.

[0009] Furthermore, the included angle of the air duct guide groove at its widest point on both sides of the suction cup front cover is 120-160 degrees. Since the included angle of the air duct guide groove on both sides of the suction cup rear cover is relatively large, it can easily absorb water accumulated on the ground.

[0010] Furthermore, the positioning and mounting component includes a fixing hole on the air duct guide groove and a fixing pin on the suction cup front cover. The suction cup front cover is connected to the fixing hole on the air duct guide groove through the fixing pin. The fixing hole and fixing pin can strengthen the fixation of the air duct guide groove.

[0011] Furthermore, the air duct guide groove is provided with a sealing groove, which can prevent water from being sucked into the installation gap of the suction nozzle.

[0012] Furthermore, the sealing groove is provided with sealant, which can further enhance the sealing performance.

[0013] Furthermore, a support and positioning piece is provided between the air duct guide groove and the suction cup front cover. The support and positioning piece can further strengthen the fixation of the air duct guide groove.

[0014] Furthermore, the support positioning plate, the air duct guide groove, and the suction cup front cover are integrated into one piece, which effectively simplifies the structure of the suction cup.

[0015] Furthermore, it also includes positioning screws. The suction cup rear cover is provided with positioning mounting holes, and the suction cup front cover is provided with positioning mounting seats. The positioning screws pass through the positioning mounting holes on the suction cup rear cover and are fixed on the positioning mounting seats on the suction cup front cover. The positioning mounting seats and positioning mounting holes facilitate the fixing between the suction cup front cover and the suction cup rear cover.

[0016] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0017] The novel suction cup disclosed in this utility model has an outward protruding shape at the connection between the air duct guide groove and the suction cup pipe interface, and the connection between the air duct guide groove and the suction cup pipe interface is quickly narrowed to form a funnel shape. Therefore, the suction force can be more concentrated, while avoiding the situation where water can easily accumulate in the concave area and the water flow rate can be slowed down.

Detailed Implementation

[0023] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-4 As shown, a novel suction cup includes a front cover 1 and a rear cover 2 disposed on the front cover 1. The rear cover 2 is provided with a suction tube interface 3, and the front cover 1 is provided with an air duct guide groove 4 connected to the suction tube interface 3. The connection between the air duct guide groove 4 and the suction tube interface 3 protrudes outward, causing the connection between the air duct guide groove 4 and the suction tube interface 3 to narrow rapidly into a funnel shape. By setting the connection between the air duct guide groove 4 and the suction tube interface 3 to protrude outward and causing the connection between the air duct guide groove 4 and the suction tube interface 3 to narrow rapidly into a funnel shape, the suction force can be more concentrated while avoiding the situation where water can easily accumulate in the concave area and the water flow rate can be slowed down.

[0026] In this invention, the angle between the air duct guide groove 4 and the narrowest part of the suction pipe interface 3 is 90-120 degrees. Due to the outward protrusion of the connection between the air duct guide groove 4 and the suction pipe interface 3, the angle between the air duct guide groove 4 and the narrowest part of the suction pipe interface 3 is 90-120 degrees. This can prevent water from accumulating in the concave area and also prevent the water flow rate from slowing down. The angle between the air duct guide groove 4 and the widest part of the suction pipe front cover 1 is 120-160 degrees. Because the angle between the air duct guide groove 4 and the suction pipe front cover 1 is large, it is convenient to absorb water accumulated on the ground.

[0027] Among them, a sealing groove 9 is provided on the air duct guide groove 4. The sealing groove 9 can prevent water from being sucked into the installation gap of the suction nozzle. In practical applications, a sealant 5 can also be provided on the sealing groove 9. The sealing performance can be further enhanced by the sealant 5.

[0028] In addition, a support positioning piece 8 is provided between the air duct guide groove 4 and the suction cup front cover 1. The support positioning piece 8 can further strengthen the fixation of the air duct guide groove 4. The support positioning piece 8, the air duct guide groove 4 and the suction cup front cover 1 are integrated structures. The integrated support positioning piece 8, the air duct guide groove 4 and the suction cup front cover 1 can effectively simplify the structure of the suction cup.

[0029] In this utility model, a positioning screw is also included. The suction cup rear cover 2 is provided with a positioning mounting hole 6, and the suction cup front cover 1 is provided with a positioning mounting seat 7. The positioning screw passes through the positioning mounting hole 6 on the suction cup rear cover 2 and is fixed on the positioning mounting seat 7 on the suction cup front cover 1. The positioning mounting seat 7 and the positioning mounting hole 6 facilitate the fixing between the suction cup front cover 1 and the suction cup rear cover 2.
