[0067] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0068] Please refer to Figure 1 This utility model proposes a pump protective cover, which can be installed on a pump to protect the pump. The pump has an inlet pipe and an outlet pipe. The inlet pipe is located on one side of the pump, and the outlet pipe is located on the other side of the pump opposite to the inlet pipe or on the top surface of the pump.

[0069] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 The pump protective cover has a housing 10, a water inlet plate 20, and a water outlet plate 30. The housing 10 has a water inlet channel 11 and a water outlet channel 12. The water inlet channel 11 is formed on one side of the housing 10, and a water inlet 111 is formed on the water inlet channel 11. Therefore, when this invention is installed on a pump, the pump's water inlet pipe can pass through the housing 10 of this invention from the water inlet 111. In this embodiment, the width of the water inlet channel 11 corresponds to the diameter of the water inlet pipe. Please refer to... Figure 5 The water inlet channel 11 has two water inlet engaging parts 112, which are respectively disposed on opposite sides of the water inlet channel 11, and each water inlet engaging part 112 has at least one water inlet engaging hole 1121, which penetrates the opposite sides of the water inlet engaging part 112.

[0070] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 8A water outlet channel 12 is formed on the top surface of the housing 10 and extends to the other side of the housing 10 opposite to the water inlet channel 11. An upper water outlet 121 and a side water outlet 122 are formed on the water outlet channel 12. The upper water outlet 121 is formed on the top surface of the housing 10. The side water outlet 122 is located on the other side of the housing 10 opposite to the water inlet channel 11. Specifically, in this embodiment, the side water outlet 122 is opposite to the water inlet 111 and is coaxial with the water inlet 111. Therefore, when this invention is installed on a pump, the pump's water outlet pipe can pass through the housing 10 of this invention from either the upper water outlet 121 or the side water outlet 122. In this embodiment, the width of the water outlet channel 12 corresponds to the diameter of the water outlet pipe. The water outlet channel 12 has two upper water outlet engaging portions 123, two lower water outlet engaging portions 124, and two top water outlet engaging holes 125. Two upper water outlet engaging portions 123 are respectively disposed on opposite sides of the water outlet channel 12, and each upper water outlet engaging portion 123 has at least one upper water outlet engaging hole 1231. The two upper water outlet engaging holes 1231 penetrate through the opposite sides of the upper water outlet engaging portion 123. Lower water outlet engaging portions 124 are respectively disposed on opposite sides of the water outlet channel 12, and are located below the upper water outlet engaging portions 123. Each lower water outlet engaging portion 124 has at least one lower water outlet engaging hole 1241 and at least one lower fixing hole 1242. The lower water outlet engaging hole 1241 penetrates through the opposite sides of the lower water outlet engaging portion 124. Each lower water outlet engaging hole 1241 has a lower water outlet through hole 1243 and a lower water outlet slide 1244. The lower water outlet slide 1244 is connected to the lower water outlet through hole 1243, and the width of the lower water outlet slide 1244 is smaller than the diameter of the lower water outlet through hole 1243. Two top water outlet engaging holes 125 are formed on the top surface of the housing 10 and are respectively provided on opposite sides of the water outlet channel 12.

[0071] Please refer to Figure 5 The water inlet plate 20 is detachably disposed in the water inlet channel 11 and has multiple water inlet engaging members 21. The water inlet engaging members 21 are disposed on the side of the water inlet plate 20 facing the inside of the housing 10 and are bent downward, and each water inlet engaging member 21 can engage with one of the water inlet engaging holes 1121. In this way, the water inlet plate 20 is engaged in the water inlet channel 11 of the housing 10.

[0072] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7The water outlet plate 30 is detachably disposed in the water outlet channel 12 and has an upper fixing plate 31, an upper sealing plate 32, a side sealing plate 33, and a lower fixing plate 34. The upper fixing plate 31 is detachably disposed in the water outlet channel 12. In this embodiment, the upper fixing plate 31 can extend and bend from the top surface of the housing 10 to the side surface of the housing 10. In other embodiments, the upper fixing plate 31 may only be disposed on the side surface of the housing 10. Preferably, the upper fixing plate 31 and the housing 10 can form a shape corresponding to the outer diameter of the pump's water outlet pipe, so that the shape of the upper water outlet 121 corresponds to the outer diameter of the water outlet pipe. In this way, when the water outlet pipe passes through the upper water outlet, the upper fixing plate 31 and the housing 10 can fit against the outer wall of the water outlet pipe, preventing dust or moisture from entering the housing 10 from the gap between the water outlet pipe, the upper fixing plate 31, and the housing 10, thus contaminating and damaging the pump.

[0073] The upper fixing plate 31 has multiple upper water outlet engaging parts 311 and two top water outlet engaging parts 312. The upper water outlet engaging parts 311 are located on the side of the upper fixing plate 31 facing the inside of the housing 10 and are bent downwards, with each upper water outlet engaging part 311 capable of engaging with one of the upper water outlet engaging holes 1231. The two top water outlet engaging parts 312 are located on the side of the upper fixing plate 31 facing the inside of the housing 10, and each top water outlet engaging part 312 capable of engaging with one of the top water outlet engaging holes 125. Thus, the upper fixing plate 31 is engaged in the water outlet channel 12 by the engagement of the upper water outlet engaging parts 311 with the upper water outlet engaging holes 1231 and the engagement of the top water outlet engaging parts 312 with the top water outlet engaging holes 125. In other embodiments, the connection between the upper fixing piece 31 and the housing 10 is not limited to this, and may only have an upper water outlet locking piece 311 and an upper water outlet locking hole 1231, or a top water outlet locking part 312 and a top water outlet locking hole 125.

[0074] The upper sealing piece 32 is detachably connected to the upper fixing piece 31 and seals the upper water outlet 121 of the water outlet channel 12. In this embodiment, the joint between the upper sealing piece 32 and the upper fixing piece 31 is relatively thin. Therefore, when the user bends the joint between the upper sealing piece 32 and the upper fixing piece 31, the joint is easily damaged, causing the upper sealing piece 32 and the upper fixing piece 31 to separate from each other. In other embodiments, the connection method between the upper sealing piece 32 and the upper fixing piece 31 is not limited to this; it can also be adhesive or snap-fit, as long as the upper sealing piece 32 can be separated from the upper fixing piece 31 according to the user's needs.

[0075] The side sealing piece 33 is detachably connected to the lower side of the upper fixing piece 31 and seals the side outlet 122 of the water outlet channel 12. In this embodiment, the connection method between the side sealing piece 33 and the upper fixing piece 31 is the same as the connection method between the upper sealing piece 32 and the upper fixing piece 31. Both are separated from each other by the characteristic that the joint is thin and easily damaged.

[0076] The lower fixing piece 34 is detachably connected to the lower side of the side sealing piece 33, so the upper fixing piece 31 and the lower fixing piece 34 are located on opposite sides of the side sealing piece 33. Specifically, the upper fixing piece 31 and the lower fixing piece 34 can together form a shape corresponding to the outer diameter of the pump's outlet pipe, so that the shape of the side outlet 122 corresponds to the outer diameter of the outlet pipe. This allows the upper fixing piece 31 and the lower fixing piece 34 to fit against the outer wall of the outlet pipe when the side sealing piece 33 is separated from them, preventing dust or moisture from entering the housing 10 through the gap between the outlet pipe and the upper fixing piece 31 and the lower fixing piece 34, thus preventing contamination and damage to the pump. In this embodiment, the connection method between the side sealing piece 33 and the lower fixing piece 34 is the same as the connection method between the side sealing piece 33 and the upper fixing piece 31. Both utilize the thinness and fragility of the joint to allow the side sealing piece 33 and the lower fixing piece 34 to separate from each other.

[0077] The lower fixing piece 34 has multiple lower water outlet engaging members 341. Each lower water outlet engaging member 341 is located on the side of the lower fixing piece 34 facing inwards from the housing 10 and is bent downwards. Each lower water outlet engaging member 341 can engage with one of the lower water outlet engaging holes 1241. Thus, by engaging the lower water outlet engaging members 341 with the lower water outlet engaging holes 1241, the lower fixing piece 34 is secured in the water outlet channel 12. Please refer to... Figure 8 In this embodiment, each lower water outlet engaging member 341 has a lower water outlet protrusion 3411, which is located at the end of the lower water outlet engaging member 341 and protrudes towards the outer surface of the lower fixing piece 34. Each lower fixing hole 1242 is disposed below one of the lower water outlet slides 1244. When each lower water outlet engaging member 341 is engaged with one of the lower water outlet engaging holes 1241, the lower water outlet protrusion 3411 can be disposed in one of the lower fixing holes 1242. The connection method between the water inlet plate 20 and the water inlet channel 11 and the connection method between the upper fixing piece 31 and the water outlet channel 12 in this utility model can also be the same as the connection method between the lower fixing piece 34 and the water outlet channel 12.

[0078] In use, the inlet plate 20 and outlet plate 30 can be removed from the housing 10 first, and the housing 10 can be placed over the pump. Then, depending on whether the pump's outlet pipe is located on the top surface of the pump or on the opposite side of the pump relative to the inlet pipe, the upper sealing plate 32 or the side sealing plate 33 of the outlet plate 30 can be separated. If the pump's outlet pipe is located on the top surface of the pump, the upper sealing plate 32 and the upper fixing plate 31 can be separated by bending to form an upper outlet. Then, the remaining upper fixing plate 31, side sealing plate 33, and lower fixing plate 34 of the outlet plate 30 are engaged with the outlet channel 12 of the housing 10. At this time, the upper fixing plate 31 and the housing 10 can adhere to the outer wall of the outlet pipe, preventing dust or moisture from entering the housing 10 and contaminating or damaging the pump. If the pump's outlet pipe is located on the side of the pump, the side sealing plate 33 can be separated from the upper fixing plate 31 and the lower fixing plate 34 by bending to form a side outlet. Then, the remaining upper fixing plate 31, upper sealing plate 32 and lower fixing plate 34 of the outlet plate body 30 are engaged with the outlet channel 12 of the housing 10. At this time, the upper fixing plate 31 and the lower fixing plate 34 can fit against the outer wall of the outlet pipe, so that dust or water cannot enter the housing 10 to contaminate and damage the pump.

[0079] The advantage of this utility model lies in the arrangement of the housing 10 and the water outlet plate 30, and the water outlet plate 30 is provided with a separable upper sealing plate 32 and a side sealing plate 33. In addition to protecting the pump, it can also adjust the position of the water outlet for different pump models. This allows the utility model to form a water outlet suitable for the water outlet pipe, regardless of whether the water outlet pipe of the pump is located on the top surface of the pump or on the other side of the pump opposite to the water inlet pipe.

[0080] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the present utility model's technical solution shall still fall within the scope of the present utility model's technical solution.
