Problems solved by technology

Patent CN205570600U also discloses a low-pressure cleaning machine, not a hand-held high-pressure cleaning machine. Its working pressure cannot reach or exceed the 2.5MPa pressure required by the high-pressure cleaning machine. CN205570600U does not disclose any motor cooling and waterproof sealing solutions. What is provided is not a hand-held high-pressure washer either. From the accompanying drawings of the CN205570600U manual, it can be seen that there is a cooling air vent at the tail of the motor. A vent must be left at the corresponding position on the casing, and its waterproof level cannot meet the waterproof level requirements of a hand-held high-pressure washer. And there are defects and deficiencies such as high noise and non-waterproof
[0005] As a hand-held washing machine, the high-speed operation of the motor and pump will bring about a sharp rise in temperature, which is not only transmitted to the user through the casing, the high temperature will seriously affect the comfort of use, and affect the operating efficiency and life of the machine
At the same time, the noise generated by the open casing, motor operation and fan blade rotation also directly affects the user's operating comfort.

Embodiment 1

[0060] Such as Figures 1 to 9 As shown, a hand-held high-pressure cleaner 35 includes a straight pipe spray gun 38, a motor pump unit 20, a rechargeable battery 52 and a casing 36, and the casing 36 seals and wraps the motor pump unit 20 and a rechargeable battery 52, and the rechargeable battery 52 supplies the motor pump unit 20 power supply.

[0061] The motor-pump unit 20 includes a mini-pump 21 and a motor 22. The motor 22 is connected to the mini-pump 21 to drive the mini-pump 21 to work. On the one hand, the connection here means that the motor 22 and the mini-pump 21 need to be connected in the shell 36 in structure. On the other hand, it means that the motor 22 and the mini pump 21 need to be connected in power to realize the transmission of torque.

[0062] The mini pump 21 has a pump water inlet 13 and a high pressure water outlet 14 . The high-pressure water outlet 14 is directly connected to the straight pipe spray gun 38 so that the high-pressure water flow is...

Embodiment 2

[0082] Such as Figure 10 As shown, the difference between the present embodiment and the first embodiment lies in that the power switch 44 is arranged on one side of the handle part 37 in the form of a key to realize the start-stop control of the motor pump unit 20 . The way of use is the same as that of the hand-held high-pressure cleaner in the first embodiment, so it will not be repeated.

Embodiment 3

[0084] Such as Figure 11 As shown, the difference between this embodiment and the first embodiment is that the hand-held high-pressure cleaner 35 includes a hand-held spray gun 56 and a high-pressure water pipe 55 . One end of the high-pressure water pipe 55 is connected to the high-pressure water outlet 14 , and the other end is connected to the hand-held spray gun 56 . The mini-pump 21 is axially connected to the motor 22, and accordingly, the casing 36 has an axially connected receiving portion 71 and a handle portion 37, thereby making the handheld high-pressure cleaner 35 more compact. The handle 60 of the hand-held spray gun 56 is provided with a trigger 61 for controlling the start and stop of the motor pump unit 20 .

[0085] Such as Figure 12 As shown, when in use, the hand-held high-pressure cleaner 35 can be used as a submersible pump and dropped into the bucket 59 containing the cleaning medium 58, the hand-held spray gun 56 is held by the user, and then the tr...

Abstract

A water-resistant, rechargeable amphibious high pressure washer comprises a housing (36), a motor pump unit (20) and a rechargeable battery (52). The motor pump unit comprises a motor (22) and a mini pump (21). The motor comprises a motor shaft (9), a rotor (8) and a stator iron core (7) provided inside a motor housing (29). The mini pump (13) has a pump water inlet (13) and a pump water outlet (14). The motor housing has a sealed cavity (30) and an inner housing (63). The rotor and the stator iron core are provided in the sealed cavity. The stator iron core closely fits the inner housing to form a heat conduction channel. The motor housing has at least one cooling channel (17), a water inlet (19) and a water outlet (23). The water inlet is connected to an external water source, and the water outlet is in communication with the pump water inlet. The washer uses non-circulating water to cool a motor, thereby increasing motor power and an operating pressure of the washer.

Description

technical field [0001] The invention belongs to the technical field of hand-held washing machines, and in particular relates to a waterproof rechargeable amphibious high-pressure washing machine. Background technique [0002] A high-pressure cleaner is a device that uses water or a mixture of detergents as the cleaning medium and uses high-pressure water to clean the surface of objects.
