Description

Technical Field

[0001] The invention relates to the technical field of electric tools, in particular to a high-pressure cleaning machine. Background Art

[0002] A high-pressure cleaner is a machine that uses a power device to make a high-pressure plunger pump generate high-pressure water to wash the surface of an object. It can peel off and wash away dirt to achieve the purpose of cleaning the surface of the object.

[0003] A high-pressure cleaning machine generally includes a shell, a motor, a plunger pump, a liquid inlet connector, a control mechanism, a control switch and a battery pack for power supply. When in use, the plunger pump is connected to a pipe with liquid passing through the liquid inlet connector. The operator operates the control switch to drive the control mechanism to control the motor. The rotation of the motor drives the plunger in the plunger pump to reciprocate, thereby completing the liquid suction and discharge operations.

[0004] During the use of a traditional high-pressure cleaner, if the liquid inlet connector is detached from the pipeline, due to the structural setting, the liquid can easily flow from the liquid inlet of the liquid inlet connector into the battery pack, thereby affecting the safety of use. Summary of the invention

[0005] Based on this, it is necessary to provide a high-pressure cleaning machine that can reduce the risk of liquid entering the battery pack from the liquid inlet when the liquid inlet connector is detached from the pipeline.

[0006] A high pressure cleaning machine, comprising:

[0007] The housing comprises a main body and a gripping portion which are connected to each other and arranged at an angle to each other;

[0008] a functional component, at least partially housed in the main body, the functional component comprising a motor and a pump driven by the motor;

[0009] A liquid inlet joint, one end of which is connected to the housing, and the other end of the liquid inlet joint suspended in the air is provided with a liquid inlet, and the liquid inlet is connected to the pump;

[0010] A pole piece for plugging into a battery pack, mounted on a side of the housing connected to the liquid inlet connector;

[0011] Wherein, the main body has a central axis, and the maximum distance between the pole piece and the central axis is smaller than the minimum distance between the liquid inlet and the central axis.

[0012] In this way, since the maximum distance between the pole piece and the central axis of the main body is smaller than the minimum distance between the liquid inlet and the central axis of the main body, when the high-pressure cleaning machine is used normally, the position of the liquid inlet is always lower than the position of the pole piece (the position of the pole piece is higher than the position of the liquid inlet). When the liquid inlet joint is detached from the pipeline carrying liquid, the liquid is not easy to flow into the pole piece from the liquid inlet, thereby improving the safety of the use of the high-pressure cleaning machine.

[0013] In one embodiment, the high-pressure cleaning machine also includes a battery pack mounting portion, which includes a pole piece mounting portion and a battery pack interface portion extending from the pole piece mounting portion, the pole piece mounting portion is connected to the main body portion and / or the holding portion, the pole piece is mounted on the pole piece mounting portion, and the battery pack is mounted on the battery pack interface portion and is plugged and fixed to the pole piece.

[0014] In one of the embodiments, the liquid inlet connector is connected to the main body, and the battery pack mounting portion is disposed between the liquid inlet connector and the gripping portion.

[0015] In one embodiment, the liquid inlet connector is vertically arranged to the main body, the battery pack interface portion is parallel to the holding portion, the pole piece is installed on the pole piece mounting portion along a direction parallel to the holding portion, and an angle is formed between the liquid inlet connector and the pole piece.

[0016] In one embodiment, the angle is greater than or equal to 20°.

[0017] In one of the embodiments, the battery pack interface portion is arranged parallel to the holding portion, the pole piece is installed on the pole piece installation portion along a direction parallel to the holding portion, and the liquid inlet connector is arranged parallel to the battery pack interface portion.

[0018] In one of the embodiments, the liquid inlet connector and the battery pack mounting portion are both connected to the main body, and the liquid inlet connector is spaced between the battery pack mounting portion and the gripping portion.

[0019] In one of the embodiments, the battery pack mounting portion is connected to both the main body portion and the holding portion, and the liquid inlet connector is connected to the battery pack mounting portion.

[0020] In one embodiment, the high-pressure cleaning machine further includes a battery pack, and the battery pack is inserted into the battery pack interface from bottom to top and is plugged and fixed with the electrode.

[0021] In one embodiment, the battery pack is a double pack.

[0022] A high pressure cleaning machine, comprising:

[0023] The housing comprises a main body and a gripping portion which are connected to each other and arranged at an angle to each other;

[0024] a functional component, at least partially housed in the main body, the functional component comprising a motor and a pump driven by the motor;

[0025] A liquid inlet joint, one end of which is connected to the housing, and the other end of the liquid inlet joint suspended in the air is provided with a liquid inlet, and the liquid inlet is connected to the pump;

[0026] A liquid outlet joint, one end of which is connected to an end of the main body away from the gripping portion, and the other end of which is provided with a liquid outlet, the liquid outlet being communicated with the pump;

[0027] A pole piece for plugging into a battery pack is mounted on a side of the shell connected to the liquid inlet connector, and the pole piece is located between the liquid inlet connector and the gripping portion.

[0028] In this way, the liquid inlet joint is arranged higher than the electrode liquid outlet joint, and the distance between the liquid inlet of the liquid inlet joint and the liquid outlet of the liquid outlet joint is shorter, so that the liquid flows through a short distance, reduces the exhaust time of the liquid outlet channel, and facilitates rapid liquid discharge; and because the liquid flows through a short distance, the amount of liquid in the liquid outlet channel is relatively small, so when the liquid inlet joint is separated from the pipeline carrying the liquid, the liquid is not easy to flow out from the liquid outlet and wet the electrode, thereby improving the safety of the high-pressure cleaning machine.

[0029] In one embodiment, the high-pressure cleaning machine also includes a battery pack mounting portion, which includes a pole piece mounting portion and a battery pack interface portion extending from the pole piece mounting portion, the pole piece mounting portion is connected to the main body portion and / or the holding portion, the pole piece is mounted on the pole piece mounting portion, and the battery pack is mounted on the battery pack interface portion and is plugged and fixed to the pole piece.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0039] See also Figure 1 The first embodiment of the present invention provides a high-pressure cleaning machine 100, including a shell 110, a liquid inlet connector 120 and a pole piece 130 for plugging a battery pack. The liquid inlet connector 120 is used to connect to an external pipe (water pipe) with liquid to guide the liquid into the high-pressure cleaning machine 100. The battery pack can be plugged into the pole piece 130 to power the high-pressure cleaning machine 100.

[0040] The housing 110 includes a main body 111 and a gripping portion 112. The main body 111 is used to accommodate other components of the high-pressure cleaning machine 100, such as a motor and a plunger pump. The gripping portion 112 is used for the operator to hold, and other components such as a control unit and a control switch may also be arranged on the gripping portion 112. Specifically, the main body 111 and the gripping portion 112 are arranged at an angle to each other, and the main body 111 has a central axis, and the gripping portion 112 may also have a central axis, and the two central axes intersect at a certain angle.

[0041] One end of the liquid inlet connector 120 is connected to the main body 111 and / or the gripping portion 112, and the other end is suspended and provided with a liquid inlet 121. The liquid inlet connector 120 is connected to an external pipeline through the liquid inlet 121. When the liquid enters the liquid inlet connector 120 from the pipeline, it enters the high-pressure cleaning machine 100 from the end thereof connected to the main body 111 and / or the gripping portion 112, and is sprayed out from the high-pressure cleaning machine 100 under the high pressure of the high-pressure cleaning machine 100 to clean the surface of the object.

[0042] The electrode piece 130 is mounted on the main body 111 and / or the gripping portion 112 and is located on the same side as the liquid inlet connector 120. Figure 1 In normal use, the liquid inlet connector 120 and the pole piece 130 are both located at the lower part of the housing 110 .

[0043] Specifically, the maximum distance between the pole piece 130 and the central axis of the main body 111 is less than the minimum distance between the liquid inlet 121 and the central axis of the main body 111, that is, there is a spacing h between the liquid inlet 121 and the pole piece 130 in a direction perpendicular to the central axis of the main body 111. In other words, in a direction perpendicular to the central axis of the main body 111, the liquid inlet 121 is farther away from the central axis of the main body 111 than the pole piece 130 and is located below the pole piece 130 and has a spacing h from the pole piece 130.

[0044] The high-pressure cleaning machine 100 provided in this embodiment has a maximum distance between the pole piece 130 and the central axis of the main body 111 that is smaller than the minimum distance between the liquid inlet 121 and the central axis of the main body 111. Therefore, when the high-pressure cleaning machine 100 is used normally, the position of the liquid inlet 121 is always lower than the position of the pole piece 130 (the position of the pole piece 130 is higher than the position of the liquid inlet 121). Therefore, when the liquid inlet connector 120 is detached from the pipe through which the liquid passes, the liquid is not easy to flow from the liquid inlet 121 into the pole piece 130 and into the interior of the battery pack, thereby improving the safety of the high-pressure cleaning machine 100.

[0045] In the present embodiment, the main body 111 and the gripping portion 112 are arranged perpendicular to each other, or they may be arranged at an obtuse angle to each other. Specifically, the high-pressure cleaning machine 100 also includes functional components at least partially accommodated in the main body 111, and the functional components include a motor (not shown) and a pump (not shown). Specifically, the pump is a plunger pump, and the motor and the plunger pump are both located in the first accommodation space (not shown) of the main body 111, and the liquid inlet connector 120 and the liquid outlet connector 150 (installed at the front end of the main body 111) are respectively connected to the liquid inlet end and the liquid outlet end of the plunger pump, and the battery pack supplies power to the motor, and the rotation of the motor drives the plunger in the plunger pump to reciprocate to complete the liquid suction and discharge operations. The high-pressure cleaning machine 100 also includes a control unit (not shown), a control switch (not shown) and a battery pack (not shown). The control unit is located in a second accommodation space (not shown) of the grip portion 112, the control switch is connected to the grip portion 112, the battery pack is plugged into the electrode 130 and is electrically connected to the control unit. The control unit is driven by operating the control switch to drive the motor to different working states.

[0046] In this embodiment, the grip portion 112 is a D-shaped structure. In other embodiments, the shape of the grip portion 112 is not limited. The battery pack can be a double pack (two battery packs connected in parallel) or a large-capacity single pack.

[0047] Furthermore, based on the state of the high-pressure cleaning machine 100 when it is working normally, the liquid inlet connector 120 is connected to the main body 111 and is located at the front end of the electrode 130 close to the liquid outlet connector 150, that is, the liquid inlet connector 120 is located closer to the front end of the high-pressure cleaning machine 100, so that the liquid inlet 121 is close to the liquid outlet 151 of the liquid outlet connector 150, and the liquid (water flow) flows through a shorter distance, thereby reducing the exhaust time in the water outlet channel and facilitating rapid water discharge; at the same time, since the liquid flows through a short distance, the amount of liquid in the liquid outlet channel is relatively small, so when the liquid inlet connector 120 is separated from the pipe through which the liquid passes, the liquid is not easy to flow out from the liquid outlet and wet the electrode, thereby improving the safety of use of the high-pressure cleaning machine 100.

[0048] Specifically, in this embodiment, the high-pressure cleaning machine 100 includes a battery pack mounting portion 160, the battery pack mounting portion 160 includes a pole piece mounting portion 161 and a battery pack interface portion 162 extending from the pole piece mounting portion 161, the pole piece mounting portion 161 is connected to both the main body 111 and the grip portion 112 (the pole piece mounting portion 161 is installed at the corner of the main body 111 and the grip portion 112), the pole piece 130 is installed on the pole piece mounting portion 161, and the battery pack is installed on the battery pack interface portion 162 from bottom to top and is plugged and fixed with the pole piece 130. More specifically, multiple pole pieces 130 are installed on the pole piece mounting portion 161 in parallel and at intervals. In other embodiments, the pole piece mounting portion 161 can be selected to be connected to the main body 111 or the grip portion 112 separately.

[0049] The liquid inlet connector 120 is arranged perpendicularly to the main body 111, that is, the liquid inlet connector 120 is perpendicular to the central axis of the main body 111, the battery pack interface portion 162 is arranged parallel to the grip portion 112, and the pole piece 130 is installed on the pole piece mounting portion 161 in a direction parallel to the grip portion 112. Then, at this time, there is an angle a between the liquid inlet connector 120 and the pole piece 130, so that it is convenient for the liquid inlet connector 120 to be connected to the external pipeline. Specifically, the angle a between the liquid inlet connector 120 and the pole piece 130 is set to be greater than or equal to 20°. In other embodiments, the pole piece mounting portion 161 can also be arranged perpendicularly to the main body 111. Since the battery pack interface portion 162 is an extension of the pole piece mounting portion 161, the liquid inlet connector 120 is parallel to the battery pack mounting portion 160 at this time.

[0050] Specifically, the liquid inlet connector 120 is also connected to the battery pack mounting portion 160 (the liquid inlet connector 120 and the battery pack mounting portion 160 are arranged side by side along the central axis direction of the main body 111). In other embodiments, the liquid inlet connector 120 may also be spaced apart from the battery pack mounting portion 160.

[0051] Furthermore, the pole piece 130 is installed at the top of the battery pack mounting portion 160 , and the maximum distance between the liquid inlet 121 and the central axis of the main body 111 is smaller than the maximum distance between the battery pack mounting portion 160 and the central axis of the main body 111 .

[0052] In this embodiment, the battery pack is inserted into the battery pack interface portion 162 from bottom to top, and the battery pack is lower than the electrode 130. The maximum distance between the battery pack and the central axis of the main body 111 is set to be smaller than the minimum distance between the liquid inlet 221 and the central axis of the main body 111. When the liquid inlet connector 120 is disconnected from the pipe through which the liquid passes, it is difficult for the liquid to flow into the electrode 130 from the liquid inlet 121 and into the interior of the battery pack, and it is also difficult for the liquid to enter the interior of the battery pack from the battery pack itself, thereby further improving the safety of the high-pressure cleaning machine 100.

[0053] See also Figure 2The second embodiment of the present invention provides a high-pressure cleaning machine 200, which is similar to the high-pressure cleaning machine 100 in the first embodiment and includes a housing 210, a liquid inlet connector 220 and a pole piece 230. The housing 210 includes a main body 211 and a gripping portion 212. The main body 211 and the gripping portion 212 are arranged at an angle to each other. The main body 211 has a central axis. One end of the liquid inlet connector 220 is connected to the main body 211 and / or the gripping portion 212, and the other end is suspended and provided with a liquid inlet 221. The pole piece 230 is installed on the same side of the main body 211 and / or the gripping portion 212 where the liquid inlet connector 220 is connected. At the same time, the maximum distance between the pole piece 230 and the central axis of the main body 211 is less than the minimum distance between the liquid inlet 221 and the central axis of the main body 211. The liquid inlet connector 220 is located at the front end of the pole piece 230.

[0054] The difference from the first embodiment is that in the second embodiment, the battery pack interface portion 262 is arranged in parallel with the grip portion 212 (in this case, the electrode mounting portion 261 is arranged in parallel with the grip portion 212), and the liquid inlet connector 220 is also arranged in parallel with the grip portion 212, that is, the liquid inlet connector 220 is arranged in parallel with the battery pack mounting portion 260. In other embodiments, the battery pack interface portion 262 may be arranged perpendicularly to the main body 211 (the battery pack mounting portion 260 is arranged perpendicularly to the main body 211), and the liquid inlet connector 220 may be arranged in parallel with the grip portion 212.

[0055] Specifically, the liquid inlet connector 220 and the battery pack mounting portion 260 are spaced apart from each other along the central axis direction of the main body 211 .

[0056] See also Figure 3 The third embodiment of the present invention provides a high-pressure cleaning machine 300, which is similar to the high-pressure cleaning machine 100 in the first embodiment, and includes a shell 310, a liquid inlet connector 320 and a pole piece 330. The shell 310 includes a main body 311 and a gripping portion 312. The main body 311 and the gripping portion 312 are arranged at an angle to each other. The main body 311 has a central axis. One end of the liquid inlet connector 320 is connected to the main body 311 and / or the gripping portion 312, and the other end is suspended and provided with a liquid inlet 321. The pole piece 330 is installed on the same side of the main body 311 and / or the gripping portion 312 where the liquid inlet connector 320 is connected. At the same time, the maximum distance between the pole piece 330 and the central axis of the main body 311 is less than the minimum distance between the liquid inlet 321 and the central axis of the main body 311.

[0057] The difference from the first embodiment is that in the third embodiment, the liquid inlet connector 320 is located at the rear end of the battery pack mounting portion 360 (including the pole piece mounting portion 361 and the battery pack interface portion 362), that is, the liquid inlet connector 320 is located between the battery pack mounting portion 360 and the gripping portion 312. Specifically, the liquid inlet connector 320 and the battery pack mounting portion 360 are both arranged parallel to the gripping portion 312. In other embodiments, the liquid inlet connector 320 and the battery pack mounting portion 360 may be arranged perpendicular to the main body 311, or one of the liquid inlet connector 320 and the battery pack mounting portion 360 may be arranged perpendicular to the main body 311, and the other may be arranged parallel to the gripping portion 312.

[0058] Specifically, the liquid inlet connector 320 and the battery pack mounting portion 360 are spaced apart along the central axis direction of the main body 311. In other embodiments, the liquid inlet connector 320 may also be connected to the battery pack mounting portion 360 and the grip portion 312.

[0059] Furthermore, the maximum distance between the liquid inlet 321 and the central axis of the main body 311 can be set to be greater than the maximum distance between the central axes of the battery pack mounting portion 360 and 311. In other embodiments, the maximum distance between the liquid inlet 321 and the central axis of the main body 311 can also be set to be less than the maximum distance between the central axes of the battery pack mounting portion 360 and 311.

[0060] A fourth embodiment of the present invention provides a high-pressure cleaning machine, which is similar to the high-pressure cleaning machine 100 in the first embodiment, and includes a shell, a liquid inlet connector and a pole piece. The shell includes a main body and a gripping portion, the main body and the gripping portion are arranged at an angle to each other, the main body has a central axis, one end of the liquid inlet connector is connected to the main body and / or the gripping portion, and the other end is suspended and provided with a liquid inlet, the pole piece is installed on the same side of the main body and / or the gripping portion where the liquid inlet connector is connected, and at the same time, the maximum distance between the pole piece and the central axis of the main body is less than the minimum distance between the liquid inlet and the central axis of the main body.

[0061] The difference from the first embodiment is that in the fourth embodiment, the battery pack mounting portion is connected to both the gripping portion and the main body, the liquid inlet connector is mounted on the battery pack mounting portion, and the liquid inlet of the liquid inlet connector is located directly below the electrode sheet. Specifically, the liquid inlet connector is inserted into the battery pack mounting portion and then connected to the main body.
