Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology and relates to a cleaning machine. Background Technology

[0002] Cleaning machines are common cleaning tools in daily life. They use a high-speed spray of water from a spray gun to clean the surface of objects, offering advantages such as good cleaning effect and fast cleaning speed. Cleaning machines are usually equipped with casters at the bottom, allowing users to easily move them. Common types include two-wheeled and four-wheeled cleaning machines. Two-wheeled cleaning machines have a support bracket and two symmetrically installed casters at the bottom, while four-wheeled cleaning machines have casters at each of the four corners. Examples include a cleaning machine disclosed in Chinese patent documents (authorization announcement number: CN103191900B) and a four-wheeled cleaning machine (authorization announcement number: CN309172554S). Two-wheeled cleaning machines offer more flexible turning, while four-wheeled cleaning machines provide greater stability. Both have their advantages, but existing cleaning machines cannot switch between two-wheeled and four-wheeled operation, causing some inconvenience for users. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a cleaning machine. The technical problem this invention aims to solve is the inability of existing cleaning machines to switch between two-wheel and four-wheel operation.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A cleaning machine includes a housing, characterized in that the front end of the bottom of the housing has a mounting block for mounting a ground support bracket, and the rear ends of the bottom of the housing have mounting holes for mounting rollers on both sides, the two mounting holes being coaxially arranged, and the bottom of the housing can also be detachably connected to a mounting base, with casters mounted at the four corners of the bottom of the mounting base.

[0006] When the mounting base is connected to the bottom of the cleaning machine's casing, the mounting base with four casters allows the cleaning machine to move on all four wheels. When the mounting base is removed, a ground support bracket is installed on the mounting block of the casing, and the mounting rollers are rotated in the two mounting holes, allowing the cleaning machine to move on two wheels. When the cleaning machine is not moving, the ground support bracket and the two rollers together support the main body of the cleaning machine, allowing it to be placed vertically on the ground. This allows the cleaning machine to switch between two-wheel and four-wheel movement modes according to actual usage needs, thus solving the problem that existing cleaning machines cannot switch between two-wheel and four-wheel movement.

[0007] In one of the aforementioned cleaning machines, two mounting blocks are symmetrically arranged at the front end of the machine housing. This improves the stability of the connection between the machine housing and the mounting blocks, or the stability of the support bracket.

[0008] In the aforementioned cleaning machine, the mounting block is embedded in the mounting base and connected to the mounting base by a first bolt, and the rear end of the machine housing is connected to the mounting base by several second bolts. This design facilitates assembly and disassembly while further enhancing the stability of the connection between the machine housing and the mounting block.

[0009] In the aforementioned cleaning machine, the mounting base includes a first mounting base and a second mounting base. The first mounting base has a cylindrical socket sleeve, and the second mounting base has a plug-in post. The plug-in post is inserted into the socket sleeve. The plug-in post has several first positioning holes along its axial direction, and the socket sleeve has second positioning holes. The plug-in post and the socket sleeve are fixed together by a third bolt that passes through both the second positioning hole and one of the first positioning holes. This allows the mounting base to be telescopically adjustable, thus adapting to cleaning machines of different models and sizes and improving its versatility.

[0010] In the aforementioned cleaning machine, the end of the insertion post has an elastic claw, and the socket sleeve has several slots along the axial direction, with the elastic claw engaging in one of the slots. This design facilitates assembly and disassembly while further improving the connection reliability between the first and second mounting bases.

[0011] In one of the aforementioned cleaning machines, a dust cover is detachably installed on the mounting hole. When the cleaning machine switches to four-wheel mode, the dust cover provides waterproofing and dust protection, preventing damage to internal components and making the cleaning machine more durable.

[0012] In one of the aforementioned cleaning machines, a U-shaped cover plate is also connected to the machine casing. A storage chamber for storage is formed between the cover plate and the machine casing. The top of the storage chamber is open, and the bottom is closed. This storage chamber greatly expands the storage capacity of the cleaning machine, facilitating the user's cleaning operations.

[0013] Compared with existing technologies, the advantages of this cleaning machine are: this cleaning machine can switch between two-wheel and four-wheel movement modes according to actual usage needs, thus solving the problem that existing cleaning machines cannot switch between two-wheel and four-wheel modes.

Detailed Implementation

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] A cleaning machine, as described above Figure 1-7 The device includes a housing 1. The front end of the bottom of the housing 1 has a mounting block 1a for mounting a ground support bracket 10. The rear ends of the bottom of the housing 1 each have mounting holes 1b for mounting casters 11, with the two mounting holes 1b coaxially arranged. A mounting base 2 is detachably connected to the bottom of the housing 1, and casters 3 are mounted at the four corners of the bottom of the mounting base 2. Preferably, the casters 3 are casters with brakes.

[0024] Reference Figure 2 Specifically, the mounting block 1a is embedded in the mounting base 2 and connected to the mounting base 2 by the first bolt 4, and the rear end of the housing 1 is connected to the mounting base 2 by a number of second bolts 5.

[0025] Reference Figure 3 , Figure 4 and Figure 5Furthermore, the mounting base 2 includes a first mounting base 2a and a second mounting base 2b. The first mounting base 2a has a cylindrical socket sleeve 2a1, and the second mounting base 2b has a plug-in post 2b1. The plug-in post 2b1 is inserted into the socket sleeve 2a1. The plug-in post 2b1 is provided with a plurality of first positioning holes 2b11 along the axial direction. The socket sleeve 2a1 has a second positioning hole 2a11. The plug-in post 2b1 and the socket sleeve 2a1 are fixed by a third bolt 6 that passes through both the second positioning hole 2a11 and one of the first positioning holes 2b11.

[0026] Reference Figure 2 Furthermore, a U-shaped cover plate 8 is connected to the housing 1, and a storage chamber 9 for storage is formed between the cover plate 8 and the housing 1. The top of the storage chamber 9 is open and the bottom is closed.

[0027] In this embodiment, it is preferred that the mounting block 1a has two blocks and is symmetrically arranged at the front end of the housing 1; preferably, the end of the plug post 2b1 has an elastic claw 2b12, and the socket sleeve 2a1 has a plurality of slots 2a12 opened along the axial direction, and the elastic claw 2b12 is engaged in one of the slots 2a12; preferably, a dust cover 7 is detachably provided on the mounting hole 1b.

[0028] When the bottom of the housing 1 of the cleaning machine is connected to the mounting base 2, the mounting base 2, equipped with four casters 3, enables the cleaning machine to move on four wheels. When the mounting base 2 is removed, and a ground support bracket 10 is installed on the mounting block 1a of the housing 1, and the mounting rollers 11 are rotated in the two mounting holes 1b of the housing 1, the cleaning machine can move on two wheels. When moving, the main body of the cleaning machine needs to be tilted, and it can be dragged like a suitcase. When the cleaning machine is not moving, the ground support bracket 10 and the two rollers 11 together support the main body of the cleaning machine, so that the cleaning machine can be placed vertically on the ground. Similarly, after removing the ground support bracket 10 and the two rollers 11 and reinstalling the mounting base 2, the cleaning machine can switch from two-wheel movement back to four-wheel movement. This allows the cleaning machine to switch between two-wheel and four-wheel movement states according to actual usage needs, thus solving the problem that existing cleaning machines cannot switch between two-wheel and four-wheel movement. At the same time, the mounting base 2 can be telescopically adjusted to adapt to different models and sizes of cleaning machines, improving versatility.
