[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Reference Figure 1-2 A vehicle-mounted cleaning machine pump protection and installation structure includes a pump head 10, a motor 6 protection shell 1 and a motor 6. A cavity with the same shape as the motor 6 is arranged inside the motor 6 protection shell 1, and a connecting protrusion 2 is also arranged on the top surface of the motor 6 protection shell 1. An axial hole 3 is opened in the center of the connecting protrusion 2. The motor 6 is installed inside the cavity, and the transmission shaft of the motor 6 extends out through the axial hole 3. The bottom surface of the pump head 10 is consistent with the top surface of the motor 6 protection shell 1, and a groove 9 is opened at the position of the connecting protrusion 2 on the bottom surface of the pump head 10 corresponding to the position of the connecting protrusion 2. When the pump head 10 is in a docking state with the motor 6 protection shell 1, the connecting protrusion 2 is stuck in the groove 9.

[0017] In view of the problem that the existing vehicle-mounted cleaning machine pump connection structure lacks protection and both the operating stability and service life are affected, this scheme proposes a pump protection installation structure. Specifically, the motor 6 is protectively installed inside the motor 6 protection shell 1. The internal motor 6 is protected by the motor 6 protection shell 1. The motor 6 is arranged inside the motor 6 protection shell 1, which can effectively isolate and waterproof, avoid water leakage from affecting the operation of the motor 6, and ensure the stable operation of the motor 6; at the same time, the motor 6 protection shell 1 is embedded with the pump head 10 to ensure the stability of the connection, which can make the pump operation more stable and ensure the use effect of the vehicle-mounted cleaning machine.

[0018] Furthermore, the top surface of the motor 6 protective housing 1 is symmetrically provided with fixing slots 4 along the connecting protrusions 2 , and the bottom surface of the pump head 10 is symmetrically provided with two sets of fixing buckles 8 along the grooves 9 , and the fixing buckles 8 are engaged and connected with the fixing slots 4 .

[0019] Through this technical solution, the motor 6 protective housing 1 is embedded in the groove 9 on the bottom surface of the pump head 10 through the connecting protrusion 2, and the pump head 10 is embedded in the fixing slot 4 through the fixing buckle 8. At the same time, mounting holes are set on both sides of the connecting protrusion 2 for locking and fixing the pump head 10 and the motor 6 protective housing 1. The motor 6 protective housing 1 and the pump head 10 are installed in an interlocking manner, thereby improving the connection stability between the two.

[0020] Furthermore, the interior of the groove 9 is coated with a layer of waterproof glue.

[0021] Through this technical solution, the groove 9 is connected to the connecting protrusion 2, and a waterproof glue is applied inside the groove 9, which can fully ensure the connection sealing between the connecting protrusion 2 and the groove 9 and avoid water leakage of the pump.

[0022] Furthermore, the motor 6 is arranged in the cavity of the motor 6 protection shell 1, and a waterproof protective layer 5 is arranged between the top of the motor 6 and the top of the motor 6 protection shell 1.

[0023] Furthermore, a buffer layer 7 is mounted on the side of the motor 6 .

[0024] The waterproof protective layer 5 is used to isolate and waterproof, preventing water flow in the pump head 10 from entering the internal cavity from the top of the motor 6 protective shell 1, effectively ensuring the safety of the motor 6; the buffer layer 7 on the outer layer of the motor 6 can be used for shock absorption and buffering to improve the working stability of the motor 6.

[0025] Working principle: the motor 6 is protectively installed inside the motor 6 protection shell 1, and the motor 6 is protected by the motor 6 protection shell 1. The motor 6 is arranged inside the motor 6 protection shell 1, which can effectively prevent water from leaking and affecting the operation of the motor 6, thereby ensuring the stable operation of the motor 6; the motor 6 protection shell 1 and the pump head 10 are embedded in each other, thereby ensuring the stability of the connection, and making the pump operation more stable. The waterproof protective layer 5, the buffer layer 7 and the waterproof glue further enhance the waterproof ability, thereby providing better protection for the motor 6 and better use effect.
