[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0023] Example 1

[0024] Reference Figure 1-7As illustrated, this embodiment proposes a wet / dry dual-use vacuum cleaner. To achieve flexible switching between wet and dry use, the vacuum cleaner includes a main body 1 and a housing 2. Specifically, the main body 1 is the power unit, and its core function is to generate negative pressure suction force. It introduces airflow and the object to be suctioned through the air inlet 11, and after internal processing, the airflow is discharged from the air outlet 12. The main body 1 has dual adaptability for independent use and use in conjunction with the housing 2. When used independently, it can be used directly as a dry vacuum cleaner. When used in conjunction with the housing 2, it can realize the function of wet liquid suction. It can also be used as a dry vacuum cleaner to suck dust and other objects into the housing 2. It also has signal receiving and execution capabilities, and can control the start and stop of the power mechanism according to the signal transmitted by the liquid level sensor 24.

[0025] Furthermore, to enable the opening and closing of the housing 2, and to facilitate cleaning of dust or wiping away water stains when open, the housing 2 is specifically designed as an integral load-bearing and storage component, comprising an upper shell 3 and a lower shell 4. When the upper shell 3 and the lower shell 4 are closed, they form a sealed absorption space S for accommodating adsorbed solids or liquids.

[0026] In one embodiment, the body groove 21 of the upper housing 3 provides an installation and positioning structure for the body 1, ensuring the stability of the connection between the body 1 and the housing 2. It should be noted that the installation and positioning of the body 1 and the housing 2, for example, after the body 1 is inserted into the body groove 21, its two ends are fastened by various methods such as clips or screws. This can be achieved with reference to existing technology, which is a mature technology and will not be described in detail here.

[0027] Furthermore, the negative pressure interface 31 serves as a transfer component for airflow conduction, enabling a sealed connection between the body 1 and the negative pressure channel 22; the suction interface 32 and the suction outlet 33 constitute a transfer structure for the adsorption channel, guiding the object to be adsorbed into the adsorption space S.

[0028] The first partition 41 and the second partition 42 of the lower housing 4 mainly serve as structural support and spatial guidance, improving the overall rigidity of the housing 2, while preventing excessive concentration of adsorbed objects in the absorption space S, which could lead to poor drainage. It should be noted that the first partition 41 and the second partition 42 can be lower than or equal to the height of the side wall of the lower housing 4. When they are the same height as the side wall of the lower housing 4, a notch is provided on the top of the first partition 41 to allow liquid to flow in the absorption space S.

[0029] Furthermore, the liquid level sensor 24 is a safety monitoring component that collects the liquid level signal within the suction space S in real time and transmits the signal to the control module of the machine body 1. When the suction liquid level reaches a preset threshold, it triggers the power mechanism of the machine body 1 to stop working, preventing liquid overflow. The protective HEPA filter 35 is an auxiliary protective component for the liquid level sensor 24, used to prevent solid debris from directly contacting the liquid level sensor 24, avoiding blockage or damage to the sensor probe, and ensuring monitoring accuracy. It should be noted that the liquid level sensor 24 uses, for example, a factory-supplied sensor with model number 0662384002, which is an existing sensor. Its own functions, such as collecting and transmitting liquid level signals, are based on existing mature technologies and can be implemented by referring to existing technologies; therefore, they will not be detailed here.

[0030] In one embodiment, the upper housing 3 is provided with a water level alarm indicator 38. When the water level reaches a set position, the red light of the water level alarm indicator 38 will flash. The water level alarm indicator 38 is an existing device. The red or green indicator light is driven to switch states by controlling the on / off state of the water level change control circuit. Obviously, the water level alarm indicator 38 in this embodiment can also be connected and cooperate with the liquid level sensor 24. That is, the liquid level sensor 24 detects the water level signal, and the water level alarm indicator 38 displays the status of the corresponding signal. The water level alarm indicator 38 is an existing device, and its specific implementation principle will not be described in detail.

[0031] Furthermore, the latch 5 is a connecting and locking component used to detachably fix the upper housing 3 and the lower housing 4, ensuring that the box 2 remains closed and sealed during operation to prevent air leakage or liquid spillage. It also facilitates user access for cleaning or maintenance. It should be noted that the latch 5 can adopt a simple snap-on structure, secured by bolts or pins, meeting basic locking requirements. The latch 5 structure used in this embodiment is based on existing mature technology, such as buttons commonly used on existing boxes, or box locks used on motorcycle mounting boxes. Existing technologies can be referenced for implementation, and its specific structural implementation will not be detailed here.

[0032] In one embodiment, the sealing joint between the upper shell 3 and the lower shell 4 can be a sealing ring structure to enhance the sealing of the box 2 and prevent liquid leakage; the lower shell 4 can be a structure with a drain outlet and a sealing plug to facilitate the quick discharge of liquid in the absorption space S without having to open the box 2 as a whole; the absorption space S can be a detachable inner liner structure, with the inner liner and the box 2 connected by a plug-in connection, allowing the inner liner to be removed directly during cleaning, thus improving cleaning convenience.

[0033] In one embodiment, the cover joint between the upper housing 3 and the lower housing 4 can adopt a simple fitting structure without additional sealing components, which is suitable for scenarios with low sealing requirements; the lower housing 4 can eliminate the partition structure or adopt an integral cavity design.

[0034] Furthermore, the suction pipe 23 provides a transport channel for the object to be suctioned, with its two ends respectively connecting to the suction interface 32 and various suction heads. The round nozzle 231 is suitable for cleaning objects in concentrated spot or small areas; the flat nozzle 232 is suitable for cleaning narrow areas such as crevices and corners; the extended flat nozzle 233 extends the conduction length based on the flat nozzle 232 and is suitable for cleaning long distances or deep cavities. Various suction heads are connected to the suction pipe 23 through a detachable connection method to achieve adaptation to different cleaning scenarios.

[0035] Furthermore, the tube groove 36 and the suction head slot 37 are storage structures. The shape of the tube groove 36 is adapted to the shape of the suction pipe 23 and is used to store the suction pipe 23 when it is not in use. The number and shape of the suction head slots 37 are adapted to various types of suction heads and are used to classify and store idle suction heads. Together, they achieve orderly storage of components and improve the storage convenience of the equipment.

[0036] The specific assembly of the components in this embodiment is as follows:

[0037] The body 1 and the upper shell 3 have a body groove 21 with a snap-fit ​​structure. The inner wall contour of the body groove 21 fits the outer bottom contour of the body 1 to ensure that the body 1 will not be relatively displaced after being inserted. The negative pressure interface 31 is located at the bottom of the body groove 21 and has a coaxial docking and connecting structure with the air inlet 11 of the body 1. A sealed fit is formed at the docking point to ensure that there is no airflow leakage during the negative pressure conduction process.

[0038] The edges of the upper housing 3 and the lower housing 4 are fitted together. Two latches 5 are symmetrically distributed on both sides of the housing 2. In this embodiment, the fixed end of the latch 5 is hinged to the lower housing 4, and the movable end is engaged with the latching structure of the upper housing 3. Through the latching action of the latches 5, the upper housing 3 and the lower housing 4 are tightly covered.

[0039] The liquid level sensor 24 is suspended from the bottom 34 of the upper housing 3 via a connector. Its installation position is located in the middle area of ​​the absorption space S to ensure comprehensive liquid level monitoring. The protective HEPA filter 35 is a cylindrical structure that is fitted over the liquid level sensor 24. The top of the protective HEPA filter 35 is fixedly connected to the bottom 34 of the upper housing 3. The bottom is an open structure, which does not affect the liquid contact with the liquid level sensor 24 and can also block solid debris.

[0040] The two ends of the first partition 41 are vertically fixed to the inner sidewall of the lower housing 4 to form a lateral support; the second partition 42 is U-shaped and its two ends are vertically fixed to the side of the first partition 41, and the bottom of the second partition 42 is attached to the inner bottom surface of the lower housing 4 to form a crisscross support structure, which together with the lower housing 4 constitutes a stable frame structure.

[0041] The suction pipe 23 and the suction port 32 of the upper housing 3 can be a plug-in sealed connection, with a sealing structure at the port to ensure negative pressure conduction efficiency; the suction pipe 23 and various suction heads are also plug-in connected, and the connection end of the suction head is adapted to the port contour of the suction pipe 23 to achieve detachable fixation.

[0042] It should be noted that the liquid level sensor 24 is connected to the control module of the machine body 1 via a signal line, which can be built-in. The probe of the liquid level sensor 24 is in direct contact with the liquid in the absorption space S. As the liquid level rises, the electrical signal of the sensor changes, and this change signal is converted into identifiable liquid level data and transmitted to the control module. The control module presets a safe liquid level threshold. When the received liquid level data reaches the threshold, the control module sends a stop command to the machine body 1, cutting off power and stopping operation. This control module can be an electronic control switch or controller, built into the machine body 1, such as a controller with the model number KG316TAC220V. Its signal reception and power-off control is a mature existing technology and will not be described in detail here.

[0043] It should be noted that this embodiment aims to achieve a flexible switching structure for vacuuming and water suction. It is a structural component connection. The implementation principles of other functionalities of the device itself and some installation structures are all existing and very mature technologies. For example, how the body 1 generates negative pressure, how the liquid level sensor 24 monitors and transmits signals, how to control power failure, how the body 1 and the housing 2 are installed, how the water level alarm indicator 38 flashes according to the water level, the specific structural implementation of the latch 5, etc. The above are just examples of technical issues. Of course, there should also be other technical issues that are the same as or similar to the above, all of which are existing and very mature technologies. At the same time, those skilled in the art can also refer to the accompanying drawings of this application and combine them with the existing technology to clearly obtain the implementation solution. The technical features corresponding to the technical problems to be solved are also non-essential technical features of this application. When judging whether this application is fully disclosed, it should not deviate from the core meaning. Therefore, it will not be described in detail.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description and ideas. It is neither necessary nor possible to exhaustively describe all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the technical solution of this utility model should be covered within the scope of protection of the claims of this utility model.
