Description

Technical Field

[0001] The invention relates to a pump, in particular to a pump with an improved mesh cover structure. Background Art

[0002] The existing pump includes a motor and a pump body connected together by a connector, and a mesh cover arranged at the water inlet of the pump body (used to prevent foreign matter from entering the pump body). The mesh cover is a long sheet of metal material forming a cylindrical structure. The existing mesh cover has a uniform overall thickness and is relatively thin. During the operation of the pump, it is inevitable that foreign matter will block the water inlet of the pump body. After the foreign matter is blocked, the flow rate of the water inlet becomes smaller, and the suction force of the water pump is still very large. At this time, the mesh cover will be sucked flat. The deflated mesh cover fails because it cannot recover its deformation, which makes the water pump unable to be used normally. Summary of the invention

[0003] The purpose of the present invention is to solve the above problems existing in the prior art and provide a pump with an improved mesh structure, adding reinforcing ribs to the mesh to improve the strength of the mesh, reduce the possibility of being sucked flat, and facilitate the normal use of the water pump.

[0004] The above technical purpose of the present invention is mainly solved by the following technical solutions: a pump with an improved mesh cover structure, comprising a motor and a pump body connected together by a connecting piece, a mesh cover arranged at the water inlet position of the pump body, the mesh cover being cylindrical, the two ends of the mesh cover being respectively connected to the motor and the pump body, characterized in that reinforcing ribs are arranged in the circumferential direction of the mesh cover, and the thickness of the reinforcing ribs is greater than the thickness of the mesh cover body. Reinforcing ribs are added to the mesh cover to improve the strength of the mesh cover, reduce the possibility of being sucked flat, and facilitate the normal use of the water pump.

[0005] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures:

[0006] In order to facilitate production and processing and avoid increasing the assembly workload, the reinforcing ribs and the mesh cover are an integrated structure.

[0007] The mesh cover is formed by a long sheet-like body, and the reinforcing ribs extend along the length direction of the long sheet-like body.

[0008] The mesh cover is provided with regular water-permeable holes, each of which is in the shape of an elongated strip, and the length direction of each water-permeable hole is consistent with the axial direction of the mesh cover, that is, the length direction of each water-permeable hole is consistent with the width direction of the elongated sheet-like body. In other words, the water-permeable holes are arranged perpendicularly to the reinforcing ribs.

[0009] The long sheet body has an insert extending in the width direction, the insert and the long sheet body are an integral structure, and in the length direction of the long sheet body, the insert divides the long sheet body into a left water permeable area and a right water permeable area (see the attached manual). Figure 6 The left and right are defined by the setting direction of the left water permeable area, the left water permeable area has at least two rows of water permeable holes, the right water permeable area has at least two rows of water permeable holes, each row of water permeable holes is plural and arranged neatly, and the reinforcing ribs are arranged between two adjacent rows of water permeable holes in the same water permeable area. Usually, an axial threading groove is provided on the connecting piece, and the inserting part covers the threading groove.

[0010] The left water-permeable area and the right water-permeable area are mapped symmetrically with respect to the symmetry axis of the insertion part.

[0011] One end of the inserting part protrudes outward to form a protruding part, and the other end is concave to form a concave part, and the protruding part and the concave part cooperate with the corresponding structure on the connecting piece. A notch is provided on the ring wall at one end of the connecting piece corresponding to the position of the threading groove (generally corresponding to the motor), and a wire guiding inclined part is provided at the other end (corresponding to the pump body), then the corresponding part of the mesh cover needs to be provided with a protruding part and a concave part for cooperating with the notch and the inclined part on the connecting piece.

[0012] The long sheet-like body is provided with connection holes on both sides of the inner concave portion, so as to facilitate the lead cover plate to be fixed to the mesh cover and the connecting piece through a connecting piece.

[0013] The two ends of the long sheet-like body are respectively provided with corresponding connection holes for passing the connection piece and fixing it on the connection piece.

[0014] The invention has the following beneficial effects: 1. Adding reinforcing ribs to the mesh to improve the strength of the mesh, reduce the possibility of being sucked flat, and facilitate the normal use of the water pump. 2. In order to facilitate production and processing and avoid increasing the workload of assembly, the reinforcing ribs and the mesh are an integrated structure. 3. Connecting holes are respectively provided on both sides of the inner concave portion of the long sheet body to facilitate the lead cover to be fixed to the mesh and the connecting piece through the connecting piece.

[0021] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] Example: Figure 1-6 As shown, the pump with improved mesh structure includes a motor 1 and a pump body 2 connected together by a connector 3, and a mesh 4 arranged at the water inlet of the pump body. The mesh is cylindrical, and the two ends of the mesh are respectively connected to the motor and the pump body. Reinforcement ribs 41 are arranged in the circumferential direction of the mesh, and the thickness of the reinforcement ribs is greater than the thickness of the mesh body. Adding reinforcement ribs to the mesh improves the strength of the mesh, reduces the possibility of being sucked flat, and is conducive to the normal use of the water pump.

[0023] In order to facilitate production and processing and avoid increasing the assembly workload, the reinforcing ribs and the mesh cover are an integrated structure.

[0024] In order to increase the reinforcement effect, the reinforcement ribs are divided into several sections and are evenly distributed on the mesh cover.

[0025] The mesh cover is formed by a long sheet body, and the reinforcing ribs extend along the length direction of the long sheet body. After the long sheet body is coiled into a cylindrical shape, the reinforcing ribs are distributed in the circumferential direction.

[0026] The mesh cover is provided with regular water-permeable holes 42, each of which is in the shape of an elongated strip, and the length direction of each of which is consistent with the axial direction of the mesh cover, that is, the length direction of each of which is consistent with the width direction of the elongated sheet-like body. In other words, the water-permeable holes 42 are arranged perpendicular to the reinforcing ribs 41.

[0027] The long sheet body has an inserting portion 43 extending in the width direction, and the inserting portion and the long sheet body are an integral structure. In the length direction of the long sheet body, the inserting portion divides the long sheet body into a left water-permeable area 46 and a right water-permeable area 47. The left water-permeable area has at least two rows of water-permeable holes, and the right water-permeable area has at least two rows of water-permeable holes. Each row of water-permeable holes is plural and arranged neatly, and the reinforcing ribs are arranged between two adjacent rows of water-permeable holes in the same water-permeable area. Usually, an axial threading groove is provided on the connector, and the inserting portion covers the threading groove.

[0028] The left water-permeable area and the right water-permeable area are symmetrically mapped with respect to the symmetry axis of the inserting portion 43 .

[0029] One end of the inserting part protrudes outward to form a protruding part 43-1, and one end is concave to form a concave part 43-2, and the protruding part and the concave part cooperate with the corresponding structure on the connecting piece. A notch 31 is provided on the ring wall at one end of the connecting piece 3 corresponding to the position of the threading groove (generally corresponding to the motor), and a wire guiding inclined part 32 is provided at the other end (corresponding to the pump body), then the corresponding part of the mesh cover needs to be provided with a protruding part and a concave part for cooperating with the notch 31 and the inclined part 32 on the connecting piece.

[0030] The long sheet-like body is provided with connection holes 44 on both sides of the inner recess 43 - 2 , so as to facilitate the lead cover plate to be fixed to the mesh cover and the connecting piece through a connecting piece.

[0031] Corresponding connecting holes 45 are respectively provided at both ends of the long sheet-like body for passing connecting pieces through and fixing them on the connecting pieces.
