Description

[Technical Field]

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a press-type pressure-adjustable cleaning spray head, a container washer and its cleaning water tank. [Background technology]

[0002] In laboratories and kitchens, glassware often needs to be cleaned, leading to the use of many different types of cleaning equipment, including ultrasonic cleaning, high-pressure spray cleaning, laser cleaning, steam cleaning, dry ice cleaning, and combined cleaning equipment. Spray cleaning is more suitable for cleaning glassware due to its high cleaning efficiency and low cleaning costs, and is therefore relatively inexpensive and widely used. The "Glass Rinser Cup Washer" in particular is easy to install, occupies a small space, cleans quickly, and leaves no residue, making it suitable for use in laboratories, home kitchens, bars, coffee shops, milk tea shops, hotels, and other settings. This washer primarily consists of a cleaning tray and a pressure-adjustable cleaning spray head. The pressure-type cleaning spray head includes a cleaning spray pipe, a sealing slide, a cleaning nozzle, and a return spring. The cleaning nozzle is equipped with a pressure-adjustable freewheel for easily inverting instruments. The glassware is placed face down on the pressure flywheel, and the bottom of the glassware is gently pressed down to push the pressure flywheel down. The pressure flywheel drives the washing nozzle to slide downward, which then pushes down the seal slide core in the washing spray pipe, connecting the passage in the washing spray pipe with the washing nozzle. The water flows through the passage into the washing nozzle and is sprayed out. The strong water flow thoroughly cleans the residue inside the glassware within a few seconds, and the water flows along the glassware into the washing tray and is then discharged.

[0017] Hereinafter, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without any creative efforts belong to the technical scope of the present invention.

[0018] Example 1 This embodiment provides a pressure-adjustable pressure cleaning spray head, which includes a pressure-adjustable cleaning spray head and a pressure-adjustable atomizing spray head, as shown in Figures 1 to 13. The pressure-adjustable cleaning spray head is provided with a pressing part, which, after receiving pressure, connects the water supply end and the drain end of the pressure-adjustable cleaning spray head, so that the liquid entering from the water supply end can be sprayed out from the drain end to spray cleaning an object. The drain end of the pressure-adjustable atomizing spray head is connected to the water supply end of the pressure-adjustable cleaning spray head to provide atomized liquid to the pressure-adjustable cleaning spray head, and the water supply end of the pressure-adjustable atomizing spray head is connected to a water source. The flow rate and water pressure of the press-type atomizing spray head are adjustable, and the amount of liquid sprayed and the spray pressure of the press-type cleaning spray head can be adjusted according to the size of the container and the difficulty of cleaning the container, thereby saving water resources. When the container is large or the dirt is difficult to remove, the water pressure and flow rate can be increased, and the increased water pressure can effectively remove stubborn dirt. At the same time, the increased water pressure actually has an additional effect, that is, the spray range of the press-type cleaning spray head also becomes larger.

[0019] This embodiment provides a pressure-adjustable cleaning spray head. As shown in FIGS. 1 to 13, the pressure-adjustable atomizing spray head includes an atomizing housing 221, a compression spring 222, and an atomizing core 223. A liquid supply passage 247 is provided within the atomizing core 223. An attachment passage is provided within the atomizing housing 221. The attachment passage includes a threaded passage portion 226, a swirl flow passage portion 227, and a tapered passage portion 228, which are arranged in this order along the water flow direction. A spray hole 225 communicating with the outside is provided at the tip of the tapered passage portion 228, and the diameter of the threaded passage portion 226 is larger than that of the swirl flow passage portion 227. The atomizing core 223 includes an adjusting screw portion 229, a swirl flow forming portion 230, and a circular boss portion 231, which are arranged in this order along the water flow direction. The diameter of the adjusting screw portion 229 is larger than that of the swirl flow forming portion 230. The adjusting screw portion 229 is threadedly connected to the threaded passage portion 226, the swirl flow forming portion 230 is located within the swirl flow passage portion 227, a swirl flow gap 232 is defined between the swirl flow forming portion 230 and the swirl flow passage portion 227, a discharge hole 248 is provided in the swirl flow forming portion 230, both ends of the discharge hole 248 are connected to the liquid supply passage 247 and the swirl flow gap 232, respectively, and an injection gap 233 is defined between the conical surface of the circular boss portion 231 and the conical surface of the tapered passage portion 228, preferably with the tapers of the two conical surfaces matching each other. The compression spring 222 is fitted into the swirl flow forming portion 230, both ends of the compression spring 222 abutting against the adjusting screw portion 229 and the tapered passage portion 228, respectively, forming a spiral cavity between the compression spring 222 and the swirl flow gap 232. After entering through the liquid supply passage 247, the liquid enters the swirl gap 232 through the discharge hole 248, forms a swirl flow under the action of the spiral cavity, and then passes through the downstream injection gap 233 and spray hole 225 to form atomized liquid.

[0020] Adjustment principle: By rotating adjustment screw 229 and changing the relative position of adjustment screw 229 and threaded passage 226, and adjusting the length of compression spring 222, a spiral cavity with lead adjustment function can be formed. At the same time, the relative position of adjustment screw 229 and threaded passage 226 is changed, which also changes the relative position of the conical surface of circular boss 231 and the conical surface of tapered passage 228. This changes the size of injection gap 233. A smaller size decreases the flow rate, while an increased size increases the flow rate. The greater the flow rate, the larger the atomization injection angle, and vice versa. See Figures 9 to 13 for the relationship between different injection gap 233 sizes and injection angles. Note that the flow area of ​​injection gap 233 is smaller than the cross section of swirl gap 232 (spiral cavity), so the nozzle throttle surface is located within injection gap 233.

[0021] 1 to 13, to facilitate rotation of the atomizing core 223, in this embodiment, a rotation adjustment head 224 is fixedly connected to one end of the adjustment screw portion 229 remote from the swirl flow forming portion 230. Rotating the rotation adjustment head 224 drives and rotates the adjustment screw portion 229, thereby adjusting the position of the atomizing core 223 in the mounting passage within the atomizing housing 221 and changing the size of the flow area of ​​the injection gap 233. The rotation adjustment head 224 is subjected to an anti-slip treatment to prevent slippage, such as by providing the surface of the rotation adjustment head 224 with a roughened surface, an anti-slip pattern, or a non-slip rubber sleeve, and further by forming the rotation adjustment head 224 into the shape of a polygonal bolt.

[0022] 1 to 13, the pressure-type cleaning spray head includes a cleaning spray pipe 234, a seal slide core 235, a cleaning nozzle 236, and a return spring 237. A cleaning passage is provided in the cleaning spray pipe 234, and an annular protrusion 239 is provided in the cleaning passage, which divides the cleaning passage into a connecting passage section 240 and a slide passage section 241. The seal slide core 235 is slidably connected to the center hole of the annular protrusion 239, and one end of the seal slide core 235 located within the connecting passage section 240 is provided with a limiting end 242 and a water supply hole 243. The diameter of the limiting end 242 is larger than the center hole of the annular protrusion 239 to prevent the seal slide core 235 from sliding completely into the slide passage section 241. A transition passage 244 is provided within the seal slide core 235, and the transition passage 244 communicates with the connecting passage portion 240 via a water supply hole 243. The water supply hole 243 may be sealed by an annular protrusion 239 when the seal slide core 235 moves away from the connecting passage portion 240. The cleaning nozzle 236 is slidably connected within the slide passage portion 241, and one end of the seal slide core 235 located at the slide passage portion 241 is fixedly connected to the cleaning nozzle 236. Preferably, the seal slide core 235 is threadedly connected to the slide passage portion 241. A spray passage 245 is provided within the cleaning nozzle 236, and the spray passage 245 communicates with the transition passage 244. A return spring 237 is fitted into the seal slide core 235, and both ends of the return spring 237 abut against the cleaning nozzle 236 and the annular protrusion 239, respectively. A pressing portion is provided on the cleaning nozzle 236.

[0023] Operating principle: The pressing part presses away from the cleaning nozzle 236, and the pressing part drives the cleaning nozzle 236 to slide away from the cleaning nozzle 236 together with the sealing slide core 235. The water supply hole 243, which was originally sealed by the annular protrusion 239 or located in the sliding passage part 241, slides into the connecting passage part 240. The liquid sprayed from the pressure-adjustable atomizing spray head in the connecting passage part 240 passes through the water supply hole 243 and enters the transition passage 244 of the sealing slide core 235, then flows into the spray passage 245 of the cleaning nozzle 236 and is sprayed out from the cleaning nozzle 236. The larger the flow rate of the liquid sprayed from the pressure-adjustable atomizing spray head, the larger the flow rate of the liquid sprayed from the cleaning nozzle 236 and at the same time the larger the spray range. Conversely, the smaller the flow rate, the smaller the spray range.

[0024] In this embodiment, as shown in FIGS. 1 to 13, a plurality of injection holes 246 are provided at the end of the cleaning nozzle 236, and the injection holes 246 communicate with injection passages 245, so that the cleaning liquid is injected at multiple angles.

[0025] In this embodiment, the atomizing housing 221, the atomizing core 223, the cleaning spray pipe 234, the seal slide core 235, and the cleaning nozzle 236 can be made of PP material, which has high corrosion resistance and a long service life; of course, other materials with high corrosion resistance, such as stainless steel, can also be used.

[0026] Example 2 This embodiment provides a container washer, which, as shown in FIGS. 1 to 13, includes a cleaning tray 21 and the pressure-adjustable cleaning spray head 22 of the first embodiment. A drain port 211 is provided on the side of the cleaning tray 21 for discharging cleaning liquid spilled from the container. A water source connector 212 is provided in the center of the cleaning tray 21. The water supply end of the pressure-adjustable atomizing spray head is attached to the water source connector 212, and the entire pressure-adjustable cleaning spray head 22 is perpendicular to the cleaning tray 21. The pressing part of the cleaning spray head is a pressing flywheel 238, which supports the opening of the container. Pressing the container presses the pressing flywheel 238, and the diameter of the pressing flywheel 238 must be larger than the diameter of the opening of the container to be cleaned. Containers such as cups, beakers, measuring cylinders, and bowls are commonly found in laboratories, kitchens, bars, coffee shops, milk tea shops, hotels, and other settings.

[0027] Working principle: The cleaning tray 21 is installed horizontally, the entire pressure-adjustable cleaning spray head 22 is installed vertically, a container is placed upside down on the pressure-adjustable cleaning spray head 22, the container mouth is pressed by the pressure flywheel 238, the pressure flywheel 238 is pressed down, the water source is atomized by the pressure-adjustable atomizing spray head and sent into the pressure-adjustable cleaning spray head, and then sprayed into the container by the pressure-adjustable cleaning spray head for cleaning, and the washed liquid flows along the container mouth into the cleaning tray 21 and then discharged from the drain outlet 211. According to the size of the container and / or the ease of cleaning the dirt inside it, the flow rate of the pressure-adjustable atomizing spray head is adjusted, and then the spray range and spray amount of the pressure-adjustable cleaning spray head are adjusted. A large flow rate means high water pressure, which can effectively clean stubborn stains, and a large spray range ensures that the inside of a large container is effectively cleaned. A small flow rate means low water pressure, which can clean containers with easy-to-clean stains, and a small spray range only needs to meet the cleaning needs of small containers, effectively saving water.

[0028] 1 to 13, the swirl flow forming unit 230 of the pressure-adjustable atomizing spray head is threadedly connected to the water source connector 212, and preferably, the water source connector 212 is threadedly connected to the water source water supply pipe. When installing, the swirl flow forming unit 230 and the water supply pipe are screwed into both ends of the water source connector 212, respectively.

[0029] In this embodiment, as shown in Figures 1 to 13, the pressure flywheel 238 can be made of PP material, which has high corrosion resistance and a long service life, and of course, other materials with high corrosion resistance, such as stainless steel, can also be used.

[0030] Example 3 This embodiment provides a cleaning water tank, which, as shown in FIGS. 1 to 13, includes a water tank body 1, with a running water port 11 connected to the side wall of the water tank body 1. At least three container washer 2 according to embodiment 2 are installed inside the water tank body 1, and the water source connectors 212 of the three container washer 2 are connected to a detergent water source, a tap water source, and a pure water source, respectively.
