Description

Technical Field

[0001] This disclosure relates to the field of cleaning tool technology, and more specifically, to a cleaning nozzle that integrates spraying and suction. Background Technology

[0002] The spray-vacuum cleaning head has the following features: 1. It allows for washing without disassembly, similar to hand washing clothes, without damaging the material and extending the lifespan of fabrics; 2. It effectively improves cleaning efficiency, as the cleaning head directly contacts the fabric surface for on-site cleaning, eliminating the need for tedious disassembly and installation; 3. Because the cleaning head sprays and vacuums instantly without residue, there is no dripping or leakage, eliminating the need for secondary cleaning; Therefore, the spray-vacuum cleaning head is very popular for household cleaning of fabric sofas, curtains, carpets, and other items.

[0003] The water spray structure of existing cleaning squeegees is mostly a combination of a round hole spray nozzle and an outer splash guard. The structure of this type of cleaning squeegee is generally wide and thick, and the squeegee cannot reach into the gaps to clean. In addition, the cleaning force of the round hole spray nozzle is unevenly distributed, and the effective cleaning area is small. At the same time, the splash guard intercepts water by means of a barrier, and its splash prevention effect still does not meet the ideal requirements.

[0004] In addition, the spray and suction areas of existing cleaning heads are generally set in parallel, which can only achieve single-direction movement and suction during the cleaning process. Reverse or lateral movement will cause leakage and dripping.

[0005] In view of this, this design proposes a cleaning nozzle that integrates spraying and suction. Through an innovative splash-proof design, the overall structural thickness of the nozzle is effectively reduced, making it more suitable for comprehensive household cleaning.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this disclosure is to provide a cleaning nozzle that integrates spray and suction, thereby overcoming, at least to some extent, one or more problems caused by the limitations and defects of related technologies.

[0008] According to one aspect of this disclosure, a cleaning nozzle integrating spray and suction is provided, comprising a nozzle orifice plate, a nozzle body, and a spray head body; wherein...

[0009] The scraper head body includes an integral scraper head body and a water suction connector pipe. The scraper head body has a flat triangular structure, and its interior is hollow to form a semi-closed water suction chamber.

[0010] The nozzle body includes an integral nozzle and a positioning connector. The nozzle tip is a slender nozzle orifice. The nozzle is located inside the water suction chamber. The positioning connector is connected to the water supply pipe. The nozzle tip is connected to the nozzle orifice plate.

[0011] The nozzle plate is sealed at the front end of the suction chamber. The outer surface of the nozzle plate is a cleaning surface that fits against the cleaning surface. The middle part of the cleaning surface is the water spraying area, and the outer part is the water suction area. The water spraying area has water spray holes that connect to the nozzle. The water spray holes have a slender structure and are set along the length of the cleaning surface and parallel to the nozzle. Several water suction holes are set on the water suction area. The water suction holes are distributed around the water spraying area and connect to the suction chamber.

[0012] In an exemplary embodiment of this disclosure, the front end of the scraper head body has an insertion port that connects to the water suction chamber. The scraper head orifice plate is inserted into the insertion port and forms a seal with the four walls of the insertion port. The inner side of the scraper head orifice plate is provided with a leak-proof connection structure for sealing the connection nozzle and constructing a converging channel connecting the nozzle and the water spray hole.

[0013] In an exemplary embodiment of this disclosure, the leak-proof connection structure includes parallel-distributed sealing grooves and converging spray grooves. The spray holes are parallel to and pass through the converging spray grooves. The converging spray grooves are located between the two sealing grooves and are directly opposite the nozzle. Both the sealing grooves and the converging spray grooves are V-shaped structures. Correspondingly, the two ends of the nozzle are sawtooth sealing ends, and the two sides are wedge-shaped sealing edges. The wedge-shaped sealing edges are inserted into the sealing grooves. The two sides of the nozzle and the sawtooth sealing ends are respectively inserted into the sealing grooves and the converging spray grooves to form a sealing connection between the two ends of the nozzle.

[0014] In one exemplary embodiment of this disclosure, there are at least two water spray holes, which are symmetrically distributed on the inclined surfaces of the two sides of the water spray channel.

[0015] In an exemplary embodiment of this disclosure, a square conical hole is provided in the water spray area. At least one water-dividing rib is provided in the square conical hole along its length direction. The side of the water-dividing rib and the guide cone surface of the square conical hole, or the opposite side of adjacent water-dividing ribs, respectively form a guide channel connecting each water spray hole.

[0016] In one exemplary embodiment of this disclosure, the nozzle body is detachably mounted on the head body, the nozzle front end has a locking flange, and the inner side of the head orifice plate is provided with a plurality of limiting fasteners, the locking flange being locked within the limiting fasteners.

[0017] In one exemplary embodiment of this disclosure, the inner periphery of three adjacent sides of the punch plate is provided with a sealing plate with a flange structure, and the inner periphery of one side is an open port without a flange structure. Several limiting fasteners are divided into two rows and are respectively arranged on the outside of the sealing groove. The snap-fit ​​flange is inserted into the limiting area of ​​the limiting fastener through the open port.

[0018] In one exemplary embodiment of this disclosure, the excavator body is provided with a mounting hole, the root of the positioning connector is inserted into the mounting hole and locked onto the inner end face of the mounting hole, and the threaded end of the positioning connector extends out of the excavator body and is connected to the water pipe nut for positioning the positioning connector.

[0019] In one exemplary embodiment of this disclosure, a stop plate is further provided on the inner side of the nozzle orifice plate. The stop plate is disposed opposite to the open port and is located at the end of the limiting area for quickly positioning the nozzle body.

[0020] An exemplary embodiment of this disclosure discloses a spray-suction integrated cleaning head. The head body has a flat triangular structure, with the spray head located inside the head body. A long strip of water is formed in the spray area in the middle, and a suction area is set around the spray area. The suction force constructs an invisible splash wall to effectively prevent water leakage or dripping. Since the splash-proof shell is omitted, it is beneficial to the thin design of the head body, which can meet the needs of multiple usage scenarios. At the same time, the suction area on the periphery can adsorb and adhere the cloth to the spray area in the middle under the action of suction, which can prevent the cleaning surface from detaching from the cleaning surface under the action of spray force, reliably improve the cleaning effect, and further avoid water leakage or dripping caused by detachment. Moreover, there is no dripping or residue problem when the head moves in the opposite direction or laterally.

[0021] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0035] In this example embodiment, a cleaning nozzle that integrates spraying and suction is provided, such as... Figures 1-7 As shown, it includes a nozzle orifice plate 100, a nozzle body 200, and a nozzle body 300;

[0036] Refer again Figures 3-4 The scraper head body 200 includes an integral scraper head body 210 and a water suction connector pipe 220. The water suction connector pipe 220 is connected to the drain pipe. The scraper head body 210 has a flat triangular structure that is wider at the front and narrower at the back, and extends to the drain pipe. The scraper head body 210 is hollow inside to form a semi-closed water suction chamber 212. The water suction chamber 212 is connected to the water suction connector pipe 220. The thickness of the scraper head body 210 is smaller than the diameter of the water suction connector pipe 220. This is partly due to the design of thinning the scraper head body 210, and partly to facilitate the formation of a pressure difference at the rear end of the water suction chamber 212, thereby improving the water suction efficiency.

[0037] The nozzle body 300 is used to spray cleaning solutions or high-temperature water. (See again...) Figure 4 and Figure 7It includes an integral nozzle 320 and a positioning connector 330. The nozzle 320 is also a flat triangular structure that is wider at the front and narrower at the back. It is located in the middle of the water suction chamber 212. The nozzle 320 forms a flat water spray chamber inside. The front end of the water spray chamber is a slender nozzle. The positioning connector 330 is used to connect to the water supply pipe. The front end of the nozzle 320 is connected to the head orifice plate 100.

[0038] like Figure 5 As shown, the nozzle plate 100 seals the front port of the suction chamber 212. Its outer surface is the cleaning surface 110, which fits against the cleaning surface of the fabric. The nozzle plate 100 integrates water spraying and suction. The middle of the cleaning surface 110 is the water spraying area 112, and the outer periphery is the suction area. Water spraying holes connected to the nozzle 320 are opened in the water spraying area 112. The water spraying holes have a slender structure and are set along the length of the cleaning surface 110 and parallel to the nozzle. They are used to cooperate with the nozzle to form a long and flat high-pressure water jet perpendicular to the forward and backward movement direction. Therefore, compared with a cylindrical high-pressure water jet, the long and flat high-pressure water jet can evenly distribute the cleaning force across the single-pass cleaning width. This achieves effective cleaning of the entire single-pass area, improving cleaning efficiency. In addition, by setting up a water absorption area around the water spray area 112, an invisible splash wall is constructed with suction force, effectively preventing water leakage or dripping, and reducing the thickness of the head body 210. Several water absorption holes are distributed around the water spray area 112, which are connected to the water absorption chamber 212, and can collect splashed water and residual water on all four sides of the water spray area 112. Furthermore, the outer water absorption area can adsorb and adhere the cloth to the central water spray area 112 under the action of suction, which can prevent the cleaning surface from detaching from the cleaning surface 110 under the action of spray force. This not only reliably improves the cleaning effect, but also avoids water leakage or dripping caused by detachment.

[0039] In an exemplary embodiment of this disclosure, the perforated plate 100 of the excavator head is a detachable structure. The front end of the excavator head body 210 is located at the fitting port 211 at the front end of the water suction chamber 212. The perforated plate 100 of the excavator head is fitted into the fitting port 211. The fitting port 211 and the peripheral wall of the perforated plate 100 of the excavator head can be provided with a matching detachable press-lock structure. By setting a sealing ring or adopting a transition fit, the perforated plate 100 of the excavator head and the four walls of the fitting port 211 are sealed.

[0040] The inner side of the nozzle orifice plate 100 is provided with a leak-proof connection structure 160. When the nozzle orifice plate 100 is installed, the nozzle orifice plate 100 and the nozzle body 300 are reliably sealed, so that the nozzle orifice plate 100 is sealed to the nozzle and a converging channel connecting the nozzle and the water spray hole is constructed.

[0041] Specifically, an exemplary embodiment of the leak-proof connection structure 160 of this disclosure is as follows: Figures 6-7As shown, the leak-proof connection structure 160 includes parallel sealing grooves 161 and jet grooves 162. The water jet holes are parallel and connected to the jet grooves 162. The jet grooves 162 form a jet channel facing the nozzle. The two sealing grooves 161 are located on both sides of the jet grooves 162. Both are V-shaped and arranged along the length direction to form a labyrinth sealing structure to seal the sides of the water jet holes.

[0042] Correspondingly, serrated sealing end sides 321 are formed at both ends of the nozzle of the nozzle body 300, and wedge-shaped sealing side sides 322 are formed on both sides. The wedge-shaped sealing side sides 322 are inserted into the sealing groove 161. The serrated sealing end sides 321 are inserted into the sealing groove 161 and the confluence spray groove 162 respectively, forming a sealing end side of the nozzle.

[0043] In an exemplary embodiment of this disclosure, in order to thicken the cleaning area and guide the formation of multiple elongated water columns with uniformly distributed cleaning force in the cleaning width direction, the water spraying channel 162 has at least two spraying holes, which are symmetrically distributed on the inclined surfaces of the two sides of the channel 162.

[0044] Meanwhile, a spray angle guide is provided on the other side of the spray hole to guide the water jet spray angle to be reasonably distributed and coordinated. A square conical hole 120 is provided in the spray area 112. The four walls of the square conical hole 120 are all guide conical surfaces 122. At least one water-dividing rib 123 is provided in the square conical hole 120 along its length direction. The two sides of the water-dividing rib 123 are provided with slope. Multiple spray guide channels connecting each spray hole are formed between the side of the water-dividing rib 123 and the guide conical surface 122 of the square conical hole 120, or between the opposite sides of adjacent water-dividing ribs 123.

[0045] In one exemplary embodiment of this disclosure, the nozzle body 300 is also a detachable structure, and its nozzle 320 has a snap-fit ​​flange 310 at the front end. The inner side of the nozzle orifice plate 100 is provided with a plurality of limiting fasteners 150 located outside the sealing groove 161. The limiting fasteners 150 can be fixed limiting locks or movable limiting locks. A limiting area for snapping the snap-fit ​​flange 310 is formed in the limiting fasteners 150 to ensure the sealing of the leak-proof connection structure 160.

[0046] In an exemplary embodiment of this disclosure, in order to improve the sealing effect of the periphery of the perforated plate 100, sealing plates 130 with flanged structures are provided on the inner periphery of three adjacent sides of the perforated plate 100, and an open port 131 without flanged structure is provided on the inner periphery of the remaining side. Considering that the limiting fastener 150 is preferably fixed and locked, it can ensure the tight connection between the limiting fastener 150 and the snap-fit ​​flange 310 and its connection reliability. The open port 131 can facilitate the insertion of the snap-fit ​​flange 310. This side is located in the plane of the width direction.

[0047] Several limiting fasteners 150 are divided into two rows and are respectively set on the two outer sides of the sealing groove 161.

[0048] In one exemplary embodiment of this disclosure, in order to further stabilize the nozzle body 300, the nozzle body 210 is provided with a mounting hole 213, the root of the positioning connector 330 is a positioning circle, the positioning circle is inserted into the mounting hole 213 and is locked in the inner end face of the mounting hole 213, and a sealing ring is provided on the inner end face; the threaded end of the positioning connector 330 extends out of the nozzle body 210 and is connected to the water supply pipe through a nut, so that the positioning circle is locked in the mounting hole 213 to prevent the water supply pipe from stretching and shaking the nozzle body 300.

[0049] After the nozzle plate 100 and the nozzle body 300 are snapped together, they are inserted into the mounting port 211. In order to accurately and quickly align the mounting hole 213 during installation, a stop plate 140 is also provided on the inner side of the nozzle plate 100. The stop plate 140 is located on the opposite side of the open port 131 and at the end of the limiting area.
