Description

Technical Field

[0001] This utility model belongs to the field of water pump accessories, and specifically relates to a housing for a water pump. Background Technology

[0002] The existing water pump housings are snap-fit ​​type, which has limited strength. The snap-fit ​​connection relies on the elastic deformation of the plastic or metal, making it prone to fatigue wear under long-term stress. Under the impact force of starting and stopping the water pump or fluid pulsation, it may loosen or even break, affecting the stability of the equipment. In addition, this type of housing is difficult to maintain. Precise force must be applied during disassembly to avoid damaging the snaps. After repeated disassembly and reassembly, the locking force of the snaps will decrease significantly, which will also significantly affect the frequency of parts replacement, increase maintenance difficulty, and shorten the service life, thus increasing the operating cost of the equipment. Utility Model Content

[0003] To address the issues of insufficient service life caused by the strength loss and locking force loss resulting from the snap-fit ​​connection structure used in existing pump housings, this utility model provides a water pump housing that uses threaded connectors to connect the connecting post and stud to achieve the connection between the upper and lower housings, ensuring reliable connection and ideal service life.

[0011] Furthermore, a decorative shell is snapped onto the outer side of the lower housing. The lower decorative shell is provided with a second insert, which is located at the front end of the folded edge and below the first insert. The first and second inserts can be clamped vertically by the limiting slot, thereby forming a reliable connection. The lower housing and the lower decorative shell are connected by snaps and slots.

[0012] Furthermore, the housing for the water pump also includes a second enclosure plate disposed at the rear end of the upper housing and the lower housing, the second enclosure plate having an insert edge, and the rear end of the lower housing having a limiting groove, the insert edge being inserted into the limiting groove.

[0013] Furthermore, the inner side of the second enclosure is provided with two opposing baffles, each baffle having a supporting rib located near the insertion edge. The two baffles are used to shield both sides of the motor fan blades to concentrate airflow and enhance heat dissipation.

[0014] Furthermore, the inner side of the lower housing is provided with reinforcing ribs, which are located near the connecting column. These reinforcing ribs provide reinforcement.

[0015] Furthermore, the upper housing is also provided with a mounting position so that the circuit board can be mounted at the mounting position from bottom to top.

[0016] Furthermore, the upper housing is provided with an upper decorative shell, which is connected to the upper housing via snaps and slots. The upper decorative shell covers the open areas of the upper housing, effectively preventing the built-in motor from being exposed, and also strengthens the upper housing.

[0027] The technical solutions of the embodiments of this utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0028] This embodiment describes a housing for a water pump, such as... Figures 1 to 8 As shown, it includes:

[0029] The upper housing 1 is used to cover the upper part of the water pump; the inner side of the upper housing 1 is provided with a stud 11, and the lower end of the stud 11 is provided with a threaded hole 111;

[0030] The lower housing 2 is used to cover the lower part of the water pump. The lower housing 2 has a side wall and a bottom wall. The side wall of the lower housing 2 is recessed to form a built-in connecting post 21. The upper part of the connecting post 21 has a downward-facing connecting hole 211. The stud 11 can be inserted from top to bottom into the top of the connecting post 21. The threaded connector is arranged from bottom to top in the connecting hole 211 and the threaded hole 111 to connect the lower housing 2 and the upper housing 1.

[0031] The stud 11 is integrally formed with the upper shell 1, and the stud 11 extends from top to bottom along the inner side of the upper shell 1. It has a certain strength and provides a relatively ideal support effect for the upper shell 1.

[0032] The side wall of the lower housing 2 is recessed to form a connecting post 21. The uneven surface forms a reinforcing structure for the side wall of the lower housing 2. The connecting post 21 and the lower housing 2 are an integral structure, which is easy to form. In addition, the connecting thread is formed from bottom to top. After connection, the main body of the threaded connector is hidden inside the lower end of the upper housing 1. This structure greatly reduces the possibility of water splashing from top to bottom coming into contact with the threaded connector.

[0033] In this application, the upper housing 1 and the lower housing 2 are connected by connecting the connecting post 21 and the stud 11 with threaded connectors. This structure has good stability and is convenient for maintenance and disassembly. It can maintain a good locking effect even after multiple disassemblies and reassemblies, and can avoid the problems of poor service life caused by the strength loss and locking force loss of snap-fit ​​structures.

[0034] The upper end of the lower housing 2 has an end edge 22, and the end edge 22 has an upwardly bent flange 23. The bottom of the upper housing 1 is provided with a slot 12, and the flange 23 is inserted into the slot 12. The flange 23 inserted into the slot 12 can effectively prevent displacement between the upper housing 1 and the lower housing 2 during pre-fitting, so as to avoid misalignment between the threaded hole 111 and the connecting hole 211.

[0035] The connecting post 21 extends upward along the end edge 22 to form a surrounding edge 24, which surrounds the lower end of the stud 11. This allows for the formation of a positioning structure before connecting the lower housing 2 and the upper housing 1, and then the upper housing 1 and the lower housing 2 are connected by threaded connectors, effectively preventing displacement and ensuring structural stability and reliability.

[0036] like Figure 7As shown, the housing for the water pump also includes a first surrounding plate 3 disposed at the front end of the upper housing 1 and the lower housing 2. The first surrounding plate 3 has a periphery, and a limiting slot 31 is provided at the periphery of the first surrounding plate 3. A first insert 13 is provided at the front end of the upper housing 1, and the first insert 13 is inserted into the limiting slot 31. The first insert 13 and the limiting slot can assist in the initial positioning of the first surrounding plate 3 to form a reliable connection. The upper part of the first surrounding plate 3 is reliably connected to the upper housing 1 by screws. The first surrounding plate 3 is provided with two clearance holes 32, one above the other, for clearance of the water pump outlet and inlet.

[0037] The lower housing 2 is snapped onto the outer side of the lower decorative shell 4. The lower decorative shell 4 is provided with a second insert 41, which is located at the front end of the folded edge 23 and below the first insert 13. The first insert 13 and the second insert 41 can be clamped by the limiting slot 31 from above and below, thus forming a reliable connection. The lower housing 2 and the lower decorative shell 4 are connected by a snap and a slot. The upper half of the folded edge 23 is hidden at the bottom of the upper housing 1, and the lower half of the folded edge 23 is hidden inside the lower decorative shell 4. The entire housing for the water pump has no exposed sharp structures, effectively preventing scratches. In addition, the lower decorative shell 4 and the lower housing 2 can be made of different materials and shapes, which facilitates the formation of diverse structures.

[0038] like Figure 8 As shown, the housing for the water pump also includes a second enclosure plate 5 disposed at the rear end of the upper housing 1 and the lower housing 2. The second enclosure plate 5 has a periphery, and an insert edge 51 is provided at the periphery of the second enclosure plate 5. A limiting groove 25 is provided at the rear end of the lower housing 2, and the insert edge 51 is inserted into the limiting groove 25. When the second enclosure plate 5 is fitted at the rear end of the upper housing 1 and the lower housing 2, its periphery is respectively embedded in the upper housing 1 and the lower housing 2. The setting of the insert edge 51 and the limiting groove 25 enables the lower housing 2 to be initially positioned with the second enclosure plate 5. The upper end of the second enclosure plate 5 is connected to the upper housing 1 by screws to form a stable and reliable structure.

[0039] The inner side of the second enclosure 5 is provided with two opposing baffles 52, and the baffles 52 are provided with supporting ribs 521, which are located on the side close to the insertion edge 51. The two baffles 52 are used to shield the sides of the motor fan blades in order to gather airflow and enhance the heat dissipation effect.

[0040] The inner side of the lower housing 2 is provided with reinforcing ribs 26. The reinforcing ribs 26 are located near the connecting column 21. Since the connecting column 21 is formed by the inward concavity of the side wall of the lower housing 2, in order to further enhance the stability of the structure, reinforcing ribs 26 are provided near the connecting column 21.

[0041] The upper housing 1 is also provided with a mounting position 14 so that the circuit board can be installed from bottom to top at the mounting position 14. In actual use, the circuit board is installed from bottom to top at the mounting position 14.

[0042] The upper housing 1 is provided with an upper decorative shell 6, which is connected to the upper housing 1 by a snap and a slot. The upper decorative shell 6 covers the hollow part of the upper housing 1, effectively preventing the built-in motor from being exposed, and the upper decorative shell 6 can strengthen the upper housing 1. The upper decorative shell 6 and the upper housing 1 can be made of different materials and shapes, which can facilitate the formation of diverse structures and ensure that the structure is beautiful and versatile.
