Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a portable cleaning device. Background Technology

[0002] Portable cleaning devices are widely used in daily cleaning scenarios due to their small size and convenient rinsing. In the prior art, related products (such as patent number CN215354970U) design the water chamber base, water pipe and switch button of the nozzle assembly into a single structure and then perform secondary injection molding on the body shell. Although this reduces the assembly process, the material difference between the switch button and the water chamber base (soft rubber, soft rubber and hard rubber combination, respectively) requires precise control of injection molding parameters during the one-piece injection molding. Furthermore, the structure in which the two are connected by a glue passage further increases the difficulty of mold design and manufacturing process complexity, making it prone to injection molding defects.

[0003] Meanwhile, another existing solution (such as patent number CN215354070U) involves setting a boss with multiple sets of interlaced flow channels (the first flow channel includes a bend, and the second flow channel is a straight flow channel) in the middle of the water cavity base to achieve water pattern switching. The boss needs to be integrally formed with the water cavity base, and its top surface needs to be tightly attached to the inner wall of the nozzle cover. This complex boss structure not only requires extremely high precision in mold processing (deviations in flow channel dimensions can easily lead to poor water flow rectification), but it is also prone to generating bubbles and shrinkage marks during injection molding due to uneven wall thickness, leading to flow channel blockage or water flow disturbance. Ultimately, this results in problems such as unstable water pressure and water pattern scattering, significantly reducing the product's yield rate and increasing production costs and after-sales maintenance pressure. Utility Model Content

[0004] This invention proposes a portable cleaning device to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A portable cleaning device includes a main body, a water distribution tray, a nozzle cover, and control buttons; The main body is equipped with a water inlet chamber and a water inlet hole communicating with the water inlet chamber; The control button is used to control the opening and closing of the water inlet. The water distribution plate is sealed around the water inlet cavity of the main body and is rotatably set relative to the water inlet cavity. The nozzle cover is installed on the outside of the water distribution plate. The water distribution plate is provided with at least one first water distribution hole. An independent flow channel is provided on the back of the water distribution plate. The independent flow channel is formed by the water passage groove, water passage and first water distribution hole provided on the back of the water distribution plate. The area on the back of the water distribution plate other than the independent flow channel is combined with the water inlet to form a water distribution area. The independent flow channel is separated from the water distribution area. A second water distribution hole is opened in the water distribution area of ​​the water distribution plate. The nozzle cover is provided with a first water outlet and a second water outlet. The first water distribution hole is connected to the first water outlet, and the second water distribution hole is connected to the second water outlet. The spray cover plate drives the water distribution plate to rotate, thereby controlling the water passage groove to connect with or offset the water inlet hole. When the water passage groove connects with the water inlet hole, water flows through an independent channel and is sprayed out from the first water outlet hole of the spray head cover plate to achieve the first water outlet pattern. When the water passage groove is offset from the water inlet hole, water flows through the water distribution area and is sprayed out from the second water outlet hole of the spray head cover plate to achieve the second water outlet pattern.

[0006] Furthermore, the first water distribution hole is located in the middle of the water distribution plate, and the second water distribution hole is eccentrically located on the water distribution plate.

[0007] Furthermore, the first water outlet is located in the middle of the spray cover, and there are multiple second water outlets, which are radially distributed around the outer periphery of the first water outlet.

[0008] Furthermore, the number of the second water distribution holes is multiple.

[0009] Furthermore, the nozzle cover and the water distribution plate are detachably assembled by means of snap-fit ​​connection or threaded connection.

[0010] Furthermore, a sealing strip is provided at the junction of the water inlet chamber and the water inlet hole in the independent flow channel to seal and separate the independent flow channel from the water distribution area within the water inlet chamber.

[0011] Furthermore, a sealing ring is provided on the mating surface of the first water distribution hole and the nozzle cover plate to seal and separate the first water outlet hole and the second water outlet hole.

[0012] Furthermore, the water-passing groove is an annular structure, and the water-passing channel is at least one channel connecting the annular structure and the first water-dividing hole.

[0013] Furthermore, the control button is installed separately from the main body via a snap-fit ​​or plug-in connection.

[0014] Furthermore, the nozzle cover plate includes a steel sheet and a rotating ring. The steel sheet is assembled in the middle of the rotating ring through a detachable structure, and a first water outlet hole and a second water outlet hole are opened on the rotating ring.

[0015] After adopting the above solution, the beneficial effects of this utility model are as follows: 1) Addressing the issue of existing technologies where "the nozzle assembly and switch button are integrally molded, resulting in complex mold designs," this device separates the control button from the main body via snap-fit / plug-in installation, eliminating the need for integrated injection molding. This avoids the challenges of controlling injection parameters due to material differences and complex mold structures such as glue passage holes. The nozzle cover and water distribution plate are detachably assembled via snap-fit / threads. The main body and water distribution plate only require simple sealing, eliminating complex bosses, reducing mold precision requirements, simplifying assembly processes, reducing injection molding defects and assembly errors, and significantly lowering production difficulty.

[0016] 2) Existing technologies with complex bosses are prone to flow channel blockage and water flow disturbance due to uneven wall thickness. The independent flow channel of the water distribution plate of this device is composed of water-passing grooves and simple channels. The structure is regular and the wall thickness is uniform. There are no complex bends in the flow channel, the water flow is rectified and stable, and problems such as water pattern scattering and insufficient pressure are reduced. This effectively improves the stability of the output water, greatly increases the yield of product water, and reduces defective losses.

[0017] 3) Existing technologies rely on precise alignment of the boss for water pattern switching, which is prone to failure. This device switches water patterns by rotating the nozzle cover to drive the water distribution plate and controlling the opening and closing of the water groove and the water inlet. The structure is simple and there is no complicated transmission. The switching is smooth and the life is long. The core components (nozzle cover, control button, etc.) are detachable. When a component is damaged, there is no need to replace the whole thing. Only the damaged part needs to be replaced, which greatly reduces the user's maintenance and usage costs and is suitable for cleaning needs in multiple scenarios. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] This utility model provides a portable cleaning device; please refer to the appendix. Figure 1-7 This portable cleaning device includes a main body 1, a water distribution tray 2, a nozzle cover 3, and a control button 4.

[0023] The main body 1 is provided with a water inlet chamber 5 and a water inlet hole 6 connected to the water inlet chamber 5. In practical applications, the water inlet hole 6 can be connected to a water source, such as a water storage bottle or an external water pipe, to provide cleaning water for the device. The control button 4 is used to control the opening and closing of the water inlet hole 6. It can adopt a push-button or rotary structure. The control button 4 is connected to a power component (not shown in the figure). The power component adopts the prior art as described in the background art. When pressed, the water in the water bottle is pressurized by the power component and sprayed out from the water inlet hole 6. When released, it resets and closes the water inlet hole 6. The water inlet principle of the water inlet hole 6 is prior art and will not be described in detail here. Furthermore, the control button 4 is installed separately from the main body 1 by a snap-fit ​​method. Specifically, a slot can be set at the corresponding position of the main body 1, and the control button 4 can be fixed by snapping into the slot. Compared with the one-piece molded structure in the background technology, this separate installation method greatly simplifies the manufacturing and assembly process.

[0024] The water distribution plate 2 is sealed around the water inlet cavity 5 of the main body 1 by a sealing ring. The sealing ring is fitted into the annular groove on the edge of the water distribution plate 2, which can not only ensure the sealing of the water inlet cavity 5 to prevent water leakage, but also allow the water distribution plate 2 to rotate relative to the water inlet cavity 5. The nozzle cover plate 3 is installed on the outside of the water distribution plate 2. The two are connected by a snap-fit ​​to achieve detachable assembly. That is, there is an elastic hook on the edge of the water distribution plate 2, and a corresponding buckle on the inside of the nozzle cover plate 3. When assembling, the hook is snapped into the buckle to fix it. When disassembling, the hook is pressed to separate it. Of course, a threaded connection can also be used. There is an external thread on the outside of the water distribution plate 2 and an internal thread on the inside of the nozzle cover plate 3. Assembly and disassembly can be achieved by rotation.

[0025] The water distribution plate 2 is provided with at least one first water distribution hole 7, which is located in the middle of the water distribution plate 2. An independent flow channel 8 is provided on the back of the water distribution plate 2. This independent flow channel 8 is formed by the water-passing groove 9, the water-passing channel 10, and the first water distribution hole 7, all connected and fitted within the water inlet cavity 5. The water-passing groove 9 is an annular structure, and the water-passing channel 10 is at least one channel connecting the annular structure and the first water distribution hole 7, allowing water to flow smoothly from the water-passing groove 9 through the channel into the first water distribution hole 7. The area on the back of the plate 2, excluding the independent flow channel 8, cooperates with the water inlet cavity 5 to form a water distribution area 11. The independent flow channel 8 is separated from the water distribution area 11. Specifically, a sealing strip 12 can be set at the junction of the independent flow channel 8 and the water distribution area 11. The sealing strip 12 is pasted into the sealing groove on the back of the water distribution plate 2 to ensure that the water in the independent flow channel 8 does not flow into the water distribution area 11. A second water distribution hole 13 is opened on the water distribution plate 2 in the water distribution area 11. The second water distribution hole 13 is eccentrically opened on the water distribution plate 2, and there can be one or more of them to ensure that the water flow is evenly sprayed out.

[0026] The nozzle cover 3 is provided with two types of water outlet holes 16 and 17 that spray different water patterns. The first water outlet hole 16 is located in the middle of the nozzle cover 3 and corresponds to and communicates with the first water distribution hole 7 of the water distribution plate 2. The second water outlet hole 17 corresponds one-to-one with the second water distribution hole 13. In this embodiment, multiple second water outlet holes 17 are radially distributed around the outer periphery of the first water outlet hole 16, so that the water flow can be sprayed evenly from different directions. To ensure that the water flow of different water patterns does not interfere with each other, the first water distribution hole 7 is located in the middle of the nozzle cover 3 and the second water distribution hole 17. A sealing ring is provided on the mating surface of the nozzle cover plate 3. The sealing ring is fitted around the outer periphery of the first water distribution hole 7 to seal and separate the first water outlet hole and the second water outlet hole. In addition, the nozzle cover plate 3 includes a steel sheet 14 and a rotating ring 15. The steel sheet 14 is assembled in the middle of the rotating ring 15 by a snap fastener. The rotating ring 15 has a first water outlet hole and a second water outlet hole. The steel sheet 14 can enhance the structural strength of the nozzle cover plate 3 and prevent deformation after long-term use. The rotating ring 15 is used to assemble with the water distribution plate 2 to facilitate the rotation of the water distribution plate 2.

[0027] The water pattern switching process of this device is as follows: When the first water pattern is needed, rotate the nozzle cover plate 3. The nozzle cover plate 3 drives the water distribution plate 2 to rotate synchronously until the water passage groove 9 connects with the water inlet hole 6. At this time, the water source flows into the water passage groove 9 through the water inlet hole 6, and then enters the first water distribution hole 7 through the water passage channel 10. Finally, it is sprayed out from the first water outlet hole 16 of the nozzle cover plate 3, forming a concentrated central water pattern. When the second water pattern is needed, continue to rotate the nozzle cover plate 3, driving the water distribution plate 2 to rotate until the water passage groove 9 and the water inlet hole 6 are misaligned. At this time, the water no longer flows into the independent flow channel 8, but flows into the water distribution area 11 of the water inlet cavity 5, and then sprays out from the second water outlet hole 17 of the nozzle cover plate 3 through the second water distribution hole 13 in the water distribution area 11. Since multiple second water distribution holes 13 are distributed, a dispersed eccentric water pattern is formed.

[0028] Since this embodiment shows a technical solution with two water distribution holes, two water outlet holes, and switching between two different water types, this case is not limited to this. A third water distribution hole, a third water outlet hole and its independent flow channel design can be designed on this basis, or even more, thereby forming a third or even more different water types technical solution.

[0029] In other embodiments, the water passage 10 can be configured as a non-straight passage, but can be an arc-shaped passage. The nozzle cover 3 and the water distribution plate 2, the control button 4 and the main body 1 can be installed by plugging in. The rest of the structure is the same as the above embodiments, which can also realize the switching between two water types, and has the advantages of simple structure and convenient assembly.

[0030] As can be seen from the above specific embodiments, this portable cleaning device, by reasonably setting the structure and cooperation relationship of each component, not only achieves stable switching between different water types, but also simplifies the manufacturing and assembly process through the design of separate installation of control button 4 and detachable assembly of each component, thus solving the problems of complex manufacturing and low water output quality in the background technology.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
