Description

Technical Field

[0001] The utility model relates to the field of water storage and filtering equipment, in particular to a water inlet filter of a stainless steel water tank. Background Art

[0002] Stainless steel water tanks are resource storage containers with large water storage capacity, safety, low pollution, and recyclable. The process of water discharge and water intake is divided into natural water intake and physical water intake. Physical water intake is to manually transport clean water into the stainless steel water tank for storage, while natural water intake is to use the water resources generated by rainfall to obtain clean water after filtering and then store it. In this context, due to the low water filtration efficiency in light rain weather, a lot of water is volatilized or deposited in the filter medium during the slow filtration of the filter medium, and a large number of water droplets will appear on the inner wall of the filter container and gradually evaporate, resulting in low water output. In addition, the cleaning of the filter is also particularly important, and the assembly and disassembly of traditional filters is very inconvenient and not conducive to cleaning.

[0003] Therefore, the existing filters need to be further improved. Utility Model Content

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0022] like Figures 1 to 5The water inlet filter of a stainless steel water tank shown in the figure includes a main body shell 1 arranged at the water inlet of the stainless steel water tank, the main body shell 1 is a detachable combined structure, and a high-pressure filter 2 that can quickly filter water and a water filter switch 3 that can be opened and closed according to the water storage amount are arranged in the main body shell 1. The water filter switch allows the filter to be opened after storing water to a certain amount before filtering water. After being opened, the rainwater can be filtered quickly and efficiently through the high-pressure filter in combination with the combined main body shell. Since the water filter switch is started after storing water to a certain amount, the rainwater with a certain amount will flow into the high-pressure filter at the moment the water filter switch is opened, and gradually form a vortex. The impact-type water flow from top to bottom can achieve a very high efficiency filtration. The rainwater opened by the water filter switch can be determined by the user's adjustment, which can be achieved by the height of the rainwater level.

[0023] This water inlet filter is installed at the front end of the water inlet of the stainless steel water tank. After the water is filtered through this filter, it can be directly fed into the stainless steel water tank for storage. More disinfection, sterilization, filtration and other equipment can also be set between this filter and the stainless steel water tank according to the water quality.

[0024] The main body shell 1 of the utility model is composed of a water storage tank 11, a closure 12, and a filter box 13 in sequence, and the main body shell 1 is cylindrical after being assembled. The water storage tank is in a basin shape, which can collect rainwater falling into it and make the water level accumulate continuously. When a certain amount of water is accumulated, the water filter switch will be turned on. The closure is in a round cake shape, which is used as an intermediate piece between the water storage tank and the filter box. It can realize the easy replacement of the filter medium and the cleaning of the filter part. The filter box can carry the filter medium. Since the three can be combined or disassembled, it is very convenient for actual use and maintenance.

[0025] The high-pressure filter 2 described in the utility model includes a filter tube 21 connected to the bottom of the water storage tank 11, a booster landslide 22 is arranged at the bottom of the filter tube 21, and multiple filter slots 23 that can be loaded with filter media are arranged on the periphery of the top of the filter box 13. A water inlet 24 connected to the booster landslide 22 is arranged on the inner side of the top of the filter slot 23, and a water outlet 25 is arranged on the outer side of the bottom of the filter slot 23. The filter tube is a tube body with multiple holes on the outer wall, and the holes can be used for water flow. Rainwater flowing down from the water storage tank will enter the filter tube, and then flow into the booster landslide through the water on the filter tube, and then flow into the water inlet through the booster landslide, and then enter the filter slot to contact with the filter medium and be filtered, and the filtered water flows out from the water outlet. The filter medium in this technical solution can be filtered in multiple stages, that is, a variety of filter media are used for step-by-step filtering, such as activated carbon, sand and gravel, diatomaceous earth, etc.

[0026] The closure member 12 of the present invention is provided with a closure cylinder 4, which is sleeved on the outside of the filter tube 21. The function of the closure cylinder is to allow rainwater flowing out of the filter tube to smoothly enter the booster slide, so the closure member can create a closed space between the water storage tank and the filter box, namely the closure cylinder.

[0027] The top of the filter tank 23 described in the utility model can be closed by the bottom wall of the closure member 12. The top of the filter tank is open, that is, when the closure member is removed, the filter medium can be directly replaced from above, which is convenient and easy to maintain and repair.

[0028] The water filter switch 3 in the utility model includes an electric push rod 31 arranged at the bottom of the booster slide 22, the movable end of the electric push rod 31 is inserted into the filter tube 21 and a closing plate 32 is arranged at the top to close the connection between the water storage tank 11 and the filter tube 21, and a water level sensor 33 is arranged on the inner wall of the water storage tank 11 and connected to the electric push rod 31. The electric push rod is started by the water in the water storage tank being stored to a horizontal plane that covers the water level sensor. At this time, the water level sensor sends a signal to the electric push rod to start it, and the movable end of the electric push rod moves upward with the closing plate, so that the closing plate no longer closes the water storage, but allows rainwater to enter the filter tube for filtering. Since it is from the closed state of the closing plate to the open state of the closing plate, rainwater will instantly enter the filter tube, generating a large impact, and the subsequent rainwater continues to pour in to accelerate the filtering speed. The setting height of the water level sensor in the technical solution can be adjusted by the user, and it can be started when the rainwater storage covers the water level sensor. The water level sensor is a prior art module.

[0029] In the utility model, sealing rubber rings are arranged between the closure member 12 and the water storage tank 11 and the filter box 13 to strengthen the sealing and prevent water leakage.

[0030] A sealing rubber ring is provided between the closing plate 32 and the water storage tank 11 in the utility model to strengthen the seal and prevent water leakage.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
