The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and cannot be understood as limitations on the present application.

[0031] like Figure 1 and Figure 2As shown, a cleaning device according to an embodiment of the present application comprises a body 1 and a cleaning head 2 connected to the body 1, wherein the cleaning head 2 is connected to the body 1 through a hose 11. A suction motor (not shown) is provided on the body 1, and a sewage suction port 7 is provided on the cleaning head 2, and the sewage suction port 7 and the suction motor are in fluid communication through a sewage suction pipe 71. A cleaning liquid supply system (not shown) is also provided on the body 1, and a nozzle device 4 is provided on the cleaning head 2, and the nozzle device 4 and the cleaning liquid supply system are in fluid communication through a liquid infusion pipe. When cleaning, the user holds the cleaning head 2 to clean the object, and the suction force generated by the suction motor can suck the dirt cleaned from the object into the cleaning device through the sewage suction port 7, and the cleaning liquid supply system sprays the cleaning liquid onto the object through the nozzle device 4, thereby improving the cleaning effect. The sewage and the dirt are sucked into the body 1 from the sewage suction port 7 together, and the body 1 is also provided with a dirt recovery system, which can separate and store the sewage and garbage from the suction airflow, thereby completing the cleaning of the surface of the object.

[0032] like Figure 2-Figure 4 As shown, the cleaning head 2 includes a body, the body includes a handheld portion 22 for the user to hold, and a cleaning portion 21 connected to the handheld portion 22. The handheld portion 22 is used for the user to hold, and the cleaning portion 21 is used to clean the surface to be cleaned. The cleaning portion 21 is used to clean the object, and the suction port 7 is arranged on the cleaning portion 21. In addition, other cleaning parts such as a cleaning brush and a steam device can be arranged on the cleaning portion 21 to clean the object with different effects. A first mounting cavity 3 for mounting a nozzle device 4 is arranged on the body, and the first mounting cavity 3 and the nozzle device 4 are arranged on the handheld portion 22. The nozzle device 4 includes a main body 41 and a nozzle portion 42 connected to the main body 41, and the cleaning liquid is sprayed outwardly through the nozzle portion 42. In this embodiment, the main body 41 is arranged in the first mounting cavity 3, and the cross-sectional shape of the main body 41 is substantially consistent with the cross-sectional shape of the first mounting cavity 3, so that when the main body 41 is in the first mounting cavity 3, its outer wall and the inner wall of the first mounting cavity 3 can be substantially fitted, thereby limiting the main body 41 from moving or rotating in the radial direction of the body. In other embodiments not shown in the figures, the cross-sectional shape of the main body 41 and the cross-sectional shape of the first mounting cavity 3 may also be inconsistent, as long as a portion of the outer wall of the main body 41 abuts against the inner wall of the first mounting cavity 3, the nozzle device 4 can be positioned in the radial direction of the main body.

[0033] like Figure 3 and Figure 4As shown, a first stopper 6 is also provided in the first installation cavity 3 on the main body, and the first stopper 6 abuts against the outer wall of the main body 41, so as to limit the axial movement of the nozzle device 4 in the main body. In one embodiment, a through hole can be provided on the first stopper 6, and a bolt hole can be provided on the outer shell of the main body 41, and the nozzle device 4 can be fixed to the first stopper 6 by bolts; so that during installation, the staff only needs to put the nozzle device 4 into the first installation cavity 3, and then fix the nozzle device 4 by bolts, and the installation is quick and convenient. It is also preferred to provide the first stopper 6 and the main body shell as an integral part, and cooperate with the first installation cavity 3 to limit the nozzle device 4, so that the nozzle device 4 can be stably installed without providing an additional installation structure in the internal space of the main body.

[0034] In another embodiment, continue to refer to Figure 2-Figure 4 The main body is also provided with a second installation cavity 5 connected to the first installation cavity 3. The first installation cavity 3 and the second installation cavity 5 are arranged on the main body along the axial direction of the main body. During installation, the nozzle device 4 is assembled from the second installation cavity 5 into the first installation cavity 3 along the axial direction of the main body. The second installation cavity 5 is used to install other components on the cleaning head such as the infusion pipeline and the valve body 54; during installation, the staff can insert the nozzle device 4 from the second installation cavity 5 into the first installation cavity 3 along the axial direction of the main body (such as Figure 4 As shown by the arrow in the middle). In this embodiment, a first stopper 6 is also provided in the first installation cavity 3. When the staff pushes the nozzle device 4 to abut against the first stopper 6, the nozzle device 4 is installed in place; a cover body 51 is also provided on the second installation cavity 5. The cover body 51 can be covered on the second installation cavity 5 by means of a clamping connection or a bolt connection, so that the components in the second installation cavity 5 are encapsulated in the cleaning head 2. In this embodiment, the cover body 51 abuts against one end of the nozzle device 4 away from the first stopper 6, and the cover body 51 acts as a second stopper and cooperates with the first stopper 6 to position the nozzle device 4 in the axial direction of the body. It is preferred to set the first installation cavity 3 to be integrally formed by the shell of the body, and since the first stopper 6 and the cover body 51 are both the shell of the body, there is no need to use bolts or set other installation structures. The installation of the nozzle device 4 can be completed by using only the shell structure of the cleaning head 2 itself, which not only saves the installation steps and improves the production efficiency, but also simplifies the internal structure of the cleaning head 2 and reduces the production cost.

[0035] In other embodiments not shown in the figures, the first limit member 6 and the second limit member can also be played by other parts of the main body shell, or by other components installed in the main body, as long as they can abut against both ends of the nozzle device 4 to position the nozzle device 4 in the axial direction of the main body.

[0036] like Figure 5As shown, the cleaning part 21 and the handheld part 22 are detachably connected, and the handheld part 22 has a mounting part 31 at one end close to the cleaning part 21; a first locking member 311 is provided on the mounting part 31, and a second locking member 211 engaged with the first locking member 311 is provided on the shell of the cleaning part 21. The mounting part 31 is inserted into the shell of the cleaning part 21 to complete the installation. Since the dirt suction port 7 and the cleaning member are provided on the cleaning part 21, the cleaning device can have different cleaning functions by replacing different cleaning parts 21 on the handheld part 22. It is preferred to arrange the nozzle device 4, the first mounting cavity 3, the second mounting cavity 5 and other main components on the handheld part 22, so that the structure of the cleaning part 21 can be simplified, thereby reducing the production cost when multiple cleaning parts 21 are equipped.

[0037] like Figure 6 and Figure 7 As shown, the cleaning portion 21 is also provided with a sprayer 81 for spraying cleaning liquid, and the sprayer 81 includes a first connecting piece 813; the handheld portion 22 is provided with a second connecting piece 9 matched with the first connecting piece 813, and the second connecting piece 9 is in fluid communication with an infusion pipeline for conveying the cleaning liquid. When the cleaning portion 21 is mounted on the handheld portion 22, the first connecting piece 813 can be in fluid communication with the second connecting piece 9, so that the cleaning liquid can be conveyed to the cleaning portion 21 and sprayed out through the sprayer 81 to achieve a specific cleaning effect. The sprayer 81 can be a self-cleaning nozzle, a steam nozzle, or a nozzle for spraying other cleaning liquids different from the cleaning liquid in the nozzle device 4. Different sprayer structures enable the cleaning portion 21 to have different cleaning effects. The present application is described in detail by taking the sprayer 81 as a self-cleaning nozzle as an example, such as Figure 6 As shown in the cross-sectional view in FIG. 1 , the internal space of the cleaning part 21 is generally divided into two areas, one area is the sewage suction pipe 71 in fluid communication with the sewage suction port 7, and the other area is the installation room 8 for installing components, and the sprayer 81 is arranged in the installation room 8. The sprayer 81 includes a spray head 811 arranged near the sewage suction port 7, a first connecting piece 813 arranged near the hand-held part 22, and a hose 812 for connecting the spray head 811 and the first connecting piece 813; the spray head 811 is in fluid communication with the sewage suction pipe 71, so that the cleaning liquid can be sprayed from the place near the sewage suction port 7 into the sewage suction pipe 71, and the cleaning liquid flows in the sewage suction pipe 71 to self-clean the sewage suction pipe 71.

[0038] like Figure 7 and Figure 2As shown, the main body 41 of the nozzle device 4 has a first water storage chamber 411 and a second water storage chamber 412 which are independent of each other, and the nozzle part 42 is in fluid communication with the first water storage chamber 411. The second connecting member 9 is arranged at one end of the main body 41 close to the cleaning part 21, and is in fluid communication with the second water storage chamber 412; the second installation chamber 5 is also provided with a first infusion tube 52 and a second infusion tube 53 which are in fluid communication with the first water storage chamber 411 and the second water storage chamber 412, respectively, and the first infusion tube 52 and the second infusion tube 53 respectively convey the cleaning liquid to the nozzle part 42 and the sprayer 81 through the first water storage chamber 411 and the second water storage chamber 412. It is preferred that the second connecting member 9 is integrally formed with the shell of the nozzle device 4, so that the second connecting member 9 is arranged on the nozzle device 4, so that when installing, the nozzle device 4 can be directly installed to simultaneously complete the installation of the second connecting member 9, which not only saves the installation steps but also eliminates the need to separately set up an installation structure for the second connecting member 9 on the cleaning head 2, thereby reducing the cost. In actual production, the cleaning portion 21 may have multiple sprayers 81, and correspondingly, the hand-held portion 22 may be provided with multiple infusion pipes and connectors connected to different sprayers 81; these connectors may be arranged on the nozzle device 4, and corresponding multiple water storage chambers may be arranged in the nozzle device 4 to connect different connectors and infusion pipes, which not only fully utilizes the internal space of the nozzle device 4, but also completes the installation of multiple connectors while installing the nozzle device 4.

[0039] like Figure 8 and Fig. 9 As shown, in this embodiment, the first installation cavity 3 is arranged on the installation portion 31, that is, the nozzle device 4 is located in the installation portion 31, which can facilitate the installation and connection between the second connection member 9 and the first connection member 813. Further, a first guide member 10 can be arranged at one end of the nozzle device 4 close to the cleaning portion 21, and a first positioning member 101 can be arranged at one end of the cleaning portion 21 close to the nozzle device 4; when the cleaning portion 21 and the handheld portion 22 are installed, the first positioning member 101 slides along the first guide member 10, thereby guiding the connection between the first connection member 813 and the second connection member 9, so as to better protect the first connection member 813 and the second connection member 9.

[0040] like Figure 7 and Figure 6As shown, in this embodiment, the nozzle device 4 includes a first shell 43 and a second shell 44 that are spliced ​​with each other, and a water storage chamber is formed between the first shell 43 and the second shell 44. The first shell 43 and the second shell 44 can be connected by gluing, ultrasonic welding, etc. The first shell 43 is arranged near the cleaning part 21, and the second connecting member 9 and the first guide member 10 are integrally formed with the first shell 43; the second shell 44 is arranged near the handheld part 22, and the first infusion tube 52 and the second infusion tube 53 are connected to the second shell 44. The nozzle part 42 includes a water delivery channel 421 that is fluidly connected to the first water storage chamber 411, and a nozzle 422 that is connected to the water delivery channel 421; the inner diameter of the water delivery channel 421 is smaller than that of the first water storage chamber 411, so as to increase the water pressure at the nozzle 422 and facilitate the spraying of the cleaning liquid. In addition, the inner wall of the nozzle 422 is preferably arranged in a trumpet shape, so as to expand the spraying area of ​​the cleaning liquid on the surface of the object to improve the cleaning effect.

[0041] The cleaning head 2 of the present application can utilize its own shell structure to quickly install the nozzle device 4, and multiple water storage chambers can be provided in the nozzle device 4, so that multiple infusion pipes can be integrated into the nozzle device 4; and multiple connecting parts are provided on the nozzle device 4, and the nozzle device 4 is used as a connecting part, so that only the nozzle device 4 needs to be installed, and these connecting parts can be installed on the cleaning head 2, which not only improves the installation efficiency but also simplifies the internal structure of the cleaning head 2.

[0042] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
