Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a detachable clean water tank for wet cleaning equipment (such as floor scrubbers, steam mops, etc.). Background Technology

[0002] In wet cleaning equipment (such as steam mops, floor scrubbers, and garment steamers), the removable water tank serves as the core water supply unit, and its performance directly affects the cleaning efficiency and long-term reliability of the equipment. Currently, the water tank structure of mainstream equipment is relatively simple, primarily serving the function of water storage. Water is then transported to downstream water-using components (such as the nozzles of the cleaning head, steam generator, or brush head water supply system) through internal pipelines. This water transport process typically relies on a miniature water pump located within the pipeline to pressurize the water in the tank and deliver it to the target location.

[0003] Because wet cleaning equipment typically supplies water directly to the water supply line from its clean water tank, impurities in the water can easily clog the pipes or nozzles. Some designs include a filter at the outlet, but replacing it requires disassembling the tank or using tools, resulting in a poor user experience. Utility Model Content

[0004] To address the aforementioned problems, one objective of this invention is to provide a water tank structure that allows for quick assembly and disassembly of the filter element without the need for specialized tools.

[0005] Therefore, this utility model provides a clean water tank suitable for detachable installation in a wet cleaning device. The clean water tank includes: a tank body with a water storage cavity formed inside, and a water tank outlet on the tank body that can be fluidly connected to the water pipe of the wet cleaning device; a water outlet pipe having a first pipe end and a second pipe end, the first pipe end being close to the bottom of the water storage cavity and fluidly connected to the water storage cavity, and the second pipe end being fluidly connected to the water tank outlet; a filter element configured to be detachably inserted into a designated position in the water outlet pipe, the filter element being configured to filter water flowing from the lower end to the upper end of the water outlet pipe; and an installation channel formed on the tank body and capable of communicating with the outside. The installation channel intersects with and is fluidly connected to the water outlet pipe, so that the user can insert or remove the filter element from the designated position in the water outlet pipe via the installation channel.

[0006] In some preferred embodiments, the water tank further includes a filter cover plate, which is detachably mounted at the mounting channel of the tank body and configured to close the mounting channel.

[0007] In some preferred embodiments, the filter cover and the filter element are integrated into a single unit.

[0008] In some preferred embodiments, the filter cover and the filter element are connected by a pin and a spring is provided between them. The spring is configured to drive the entire assembly toward the outside of the mounting channel when an elastic force is released.

[0009] In some preferred embodiments, the filter element includes a filter element support and a filter screen fixedly supported on the filter element support.

[0010] In some preferred embodiments, the filter element support includes an outer conical circumferential surface, and the filter screen is located inside the outer conical circumferential surface.

[0011] In some preferred embodiments, the filter element is made of filter cotton material.

[0012] In some preferred embodiments, the installation channel is arranged perpendicular to the water outlet pipe.

[0013] In some preferred embodiments, the designated position is close to the first port end.

[0014] In some preferred embodiments, the clean water tank further includes: a riser pipe installed in the water storage cavity, the riser pipe constituting the water outlet pipe, a support mounting portion provided at the lower part of the riser pipe, an opening provided at the lower part of the tank body and a tubular portion extending inward around the opening, the tubular portion engaging with the support mounting portion and the two together defining the installation channel.

[0015] In some preferred embodiments, a first sealing ring is provided at the joint between the tubular portion and the support mounting portion, and a second sealing ring is provided between the tubular portion and the filter element cover.

[0016] In some preferred embodiments, the top of the tank body is provided with a water inlet, the water inlet is provided with an openable water inlet cover, and the water tank outlet is located at the upper part of the tank body.

[0017] Compared with the prior art, the beneficial effects of this utility model include: by directly placing the filter element into the water outlet pipe, the water flow from the bottom of the water storage chamber to the water outlet must pass through this point, achieving full-flow filtration; the filter element adopts a detachable structure, which users can quickly install and remove by simply using the installation channel, compared with the traditional built-in filter element (which requires disassembling the water tank for replacement), the maintenance time is shortened, significantly improving the user experience; and the filtration solution of this case does not require modification of the main structure of the water tank, and the filter element is embedded in the internal space of the water outlet pipe, which almost does not occupy the additional volume of the water storage chamber, and the water storage capacity of the water tank is not affected.

[0019] This application relates to a clean water tank that can be detachably installed on wet cleaning equipment. To solve the problem of clogging at the water tank outlet, a filter cartridge is arranged in the outlet pipe, and a lateral installation channel is provided on the outlet pipe, allowing the user to insert or remove the filter cartridge by hand, which greatly facilitates the user's cleaning operation of the filter cartridge.

[0020] The present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are only used to explain the technical solution and do not limit the scope of protection.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a clean water tank 100 according to an embodiment of this application is illustrated. The clean water tank 100 includes a tank body 1, a water outlet pipe 2, a filter element 3, and an installation channel 4.

[0022] The top of the tank body 1 is provided with a water inlet (not shown in the figure). A closable water inlet cover 12 is provided at the water inlet. The interior of the tank body 1 forms a water storage chamber 13, and the upper part of the tank body 1 is provided with a water tank outlet 14; the water tank outlet 14 is used to connect the water pipe of the wet cleaning equipment.

[0023] Combination Figure 4The water outlet pipe 2 of the clean water tank 100 is used to direct water from the water storage chamber 13 to the water tank outlet 14. In this example, the water outlet pipe 2 is defined by a riser pipe 21 arranged in the water storage chamber 13. The first end 211 of the riser pipe 21 is close to the bottom of the water storage chamber 13, and the second end 212 is connected to the water tank outlet 14.

[0024] The installation channel 4 is located at the lower part of the tank body 1 and intersects with the water outlet pipe 2. In this example, the installation channel 4 is arranged perpendicularly to the water outlet pipe 2, and the inner end of the installation channel 4 intersects perpendicularly with the riser pipe 21. The outer end of the installation channel 4 leads to the outside of the tank body 1. In this example, a support mounting part 213 is provided at the lower part of the riser pipe 21. The lower part of the tank body 1 is provided with an opening 101 and a tubular part 15 extending inward around the opening 101. The tubular part 15 is coaxial with the installation channel 4 and together defines the insertion path of the filter element 3. The tubular part 15 and the support mounting part 213 are engaged and together define the installation channel 4. A sealing ring 16 is also provided at the joint between the tubular part 15 and the support mounting part 213.

[0025] The filter element 3 is inserted into a designated position within the riser 21 through the installation channel 4. In this example, this designated position is near the first pipe opening 211. Thus, water flowing from the first pipe opening 211 into the outlet pipe 2 is filtered by the filter element 3 before flowing to the second pipe opening 212. The filter element 3 can be made of filter cotton material, such as a cylindrical filter cotton core; the material is such as polyester fiber cotton, which, after being deformed by compression, is inserted into the installation channel 4 and then springs back to fit the pipe wall within the riser 21. Since filter cotton cores are relatively inexpensive materials, filter elements made from them can be directly discarded and replaced.

[0026] When the clean water tank 100 is in use, the user can push the filter element 3 horizontally into the external port of the installation channel 4 so that it is locked in the designated position in the riser 21; it can be pulled out in the reverse direction when disassembling.

[0027] Based on the above-mentioned clean water tank solution, it can avoid equipment failure caused by filter clogging, and the replacement operation does not require disassembling the water tank.

[0028] The clean water tank 100 also includes a filter element cover 5. The filter element cover 5 is detachably covered at the outer port of the installation channel 4 and is configured to close the installation channel 4. A sealing ring 17 is also provided between the filter element cover 5 and the tubular portion 15.

[0029] When the clean water tank 100 is in use, if water needs to be added, simply open the water filling cover 12 to add water to the water storage chamber 13; the water in the water storage chamber 13 flows into the first pipe end 22 of the riser 21, and flows upward to the water tank outlet 14 through the filter element 3; when the filter element 3 needs to be replaced or cleaned, open the filter element cover 5, and the user takes out the old filter element and inserts the new component.

[0030] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment of the clean water tank 100, the filter cover plate 50 and the filter element 30 are integrated into a single integral assembly 200 and are detachably installed within the mounting channel 40 of the tank body 10. Specifically, the filter cover plate 50 and the filter element 30 are connected as an integral assembly by pins 60. A compression spring 70 is provided between the filter element 30 and the filter cover plate 50. The spring 70 is configured to drive the integral assembly 200 toward the outside of the mounting channel 40 when the elastic force is released.

[0031] The filter element 30 is an injection-molded component with a filter screen embedded in it, including a filter element support 301 with a through hole 3010 and a filter screen 302 supported on the filter element support 301. The filter screen 302 is usually fixed to the filter element support 301 by means of an injection-molded insert.

[0032] The filter element support 301 has an outer conical circumferential surface 3011. The filter screen 302 is located inside the outer conical circumferential surface 3011, meaning the surface of the filter screen 302 is lower than the outer conical circumferential surface 3011. The filter element 30 is sealed to the inner wall of the corresponding channel by the outer conical circumferential surface 3011 and is pressed by a spring 70. The user can unscrew the filter element cover 50 with a simple tool. Due to the presence of the pin 60, the filter element 30 can be removed along with the cover 50 for cleaning. The function of the spring 70 is twofold: firstly, to press the filter element 30 firmly, and secondly, to pop out the cover 50 when it is removed for easy removal.

[0033] When installing the filter element 30, simply press the entire assembly 200 into the installation channel 40. The spring 70 is compressed, and the filter element cover 50 is snapped into place at the channel port. The through hole 3010 remains in fluid communication with the outlet pipe 20. When disassembling the filter element 30, use a simple tool to unscrew the filter element cover 50. The spring 70 springs back, pushing the assembly outward. The user can easily pull out the entire assembly 200 to clean or replace the filter element 30.

[0034] The above embodiments are merely illustrative examples, and those skilled in the art can make equivalent substitutions or improvements within the scope of the claims. Other embodiments, besides the exemplary embodiments shown and described herein, are also covered within the scope of this invention.
