[0001] The utility model relates to the technical field of filtering type electric wall-mounted boilers, in particular to a filtering type electric wall-mounted boiler. Background Art

[0002] Since the existing filtering electric wall-mounted boiler is directly connected to the tap water pipe, a large amount of impurities will accumulate in the filtering electric wall-mounted boiler over a long period of time, which may cause pipe blockage.

[0003] To avoid pipe blockage, a filtering mechanism is usually installed in the furnace body. However, the filter needs to be replaced after a period of use. At this time, professionals are required to open the furnace body of the filtering electric wall-mounted boiler to clean and replace it. This requires high professionalism, high labor costs for cleaning and replacement, and is relatively troublesome. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model provides a filtering type electric wall-mounted boiler.

[0005] The utility model proposes a filtering electric wall-mounted boiler, comprising a furnace body, an outer shell, and a filter screen. The outer shell is detachably mounted on the furnace body, and a sealed chamber is formed between the shell wall of the outer shell and the outer wall of the furnace body.

[0015] Figure 2 This is a cross-sectional view of the internal structure of a filtering electric wall-mounted boiler in the second state proposed by the utility model. DETAILED DESCRIPTION

[0016] Reference Figure 1 The utility model proposes a filtering electric wall-mounted boiler, comprising a furnace body 1, an outer shell 2, and a filter 3. The outer shell 2 can be detachably installed on the furnace body 1, and a sealed chamber is formed between the shell wall of the outer shell 2 and the outer wall of the furnace body 1. The water outlet end of the first tube body 11 and the water inlet end of the second tube body 12 on the furnace body 1 both extend into the sealed chamber. The filter 3 is installed in the sealed chamber to filter water flowing from the first tube body 11 to the second tube body 12.

[0017] The housing 2 and the furnace body 1 are detachably connected, including but not limited to being fixed by bolts.

[0018] The water inlet pipe composed of the first tube body 11 and the second tube body 12 delivers water to the heating component in the furnace body 1. Before being delivered into the furnace body 1, the water delivered by the first tube body 11 is filtered in the sealed chamber through the filter 3 set to enter the furnace body 1, and then enters the furnace body 1 through the second tube body 12 to prevent impurities and sand and gravel in the water from entering the furnace body 1 and causing pipe blockage. When the filter 3 needs to be replaced and cleaned, the outer shell 2 can be removed from the furnace body 1.

[0019] In the above embodiment, the filter screen 3 can be directly installed at the water outlet end of the first tube body 11, but this setting method will cause the impurities and sand to accumulate in the first tube body 11 under the action of gravity and water pressure, and accumulate on the surface of the filter screen 3, causing the filter screen 3 to be easily blocked.

[0020] In order to prevent the filter screen 3 from being easily blocked, the filter screen 3 is fitted with the bottom wall of the water inlet end of the second tube body 12. The water flowing out through the first tube body 11 flows upward in the sealed chamber toward the second tube body 12. Impurities and sand can be directly accumulated in the sealed chamber due to gravity. The filter screen 3 and the outer shell 2 are detachably connected.

[0021] The filter screen 3 is in a ring shape and can rotate around its axis relative to the second tube body 12. When the part of the filter screen 3 corresponding to the water inlet end of the second tube body 12 is blocked, the filter screen 3 can be relatively rotated to change the relative position of the filter screen 3, so that the unblocked part of the filter screen 3 is arranged relative to the water inlet end of the second tube body 12, thereby reducing the cleaning efficiency of the filter screen 3.

[0022] To facilitate the relative rotation of the filter screen 3 , the housing 2 includes an upper shell 21 adapted to be plugged into the assembly groove 13 and a lower shell 22 sealed and rotatably connected to the upper shell 21 . The top rod 4 and the filter screen 3 are coaxially fixed to the lower shell 22 .

[0023] When the shell 2 is removed from the furnace body 1, the first tube body 11 and the second tube body 12 need to be closed. At this time, valves can be installed on the first tube body 11 and the second tube body 12 for closing. However, the valves need to be closed before each cleaning. When the user forgets to close the valves, water leakage will occur, which is troublesome.

[0024] In order to facilitate automatic closing of the first tube body 11 and the second tube body 12 each time the outer shell 2 is disassembled, the first tube body 11 has an annular first sealing surface 111, and a first sealing block 112 is slidably installed above the first sealing surface 111 in the first tube body 11. The bottom wall of the first sealing block 112 can be in contact with the first sealing surface 111 to form a blockage for the water outlet end of the first tube body 11. A push rod 4 is also installed on the outer shell 2, and the push rod 4 can be in contact with the bottom wall of the first sealing block 112 to separate the first sealing block 112 from the first sealing surface 111, thereby opening the water outlet end of the first tube body 11.

[0025] During normal use, negative pressure drives water to flow toward the water outlet of the first tube body 11. At this time, the top rod 4 abuts against the first sealing block 112, the first sealing block 112 is separated from the first sealing surface 111, and the first tube body 11 is opened. Figure 1 When the housing 2 is disassembled, the top rod 4 is separated from the first sealing block 112. At this time, the first sealing block 112 is pressed downward against the first sealing surface 111 by its own gravity and water pressure, thereby blocking the water outlet of the first tube 11. For details, refer to Figure 2 .

[0026] Similarly, the second tube body 12 has an annular second sealing surface 121, and a second sealing block 122 is slidably installed above the second sealing surface 121 in the second tube body 12. The bottom wall of the second sealing block 122 can fit with the second sealing surface 121 to form a blockage for the water inlet end of the second tube body 12. The second tube body 12 also has a limiting portion 123 that can abut against the top wall of the second sealing block 122. When the second sealing block 122 abuts against the limiting portion 123, the water inlet end of the second tube body 12 is open.

[0027] During normal use, the water flow gives the second sealing block 122 an upward thrust, so that the second sealing block 122 is separated from the second sealing surface 121 and abuts against the limiting portion 123, and the water inlet end of the second tube body 12 is open. Figure 1 When the outer shell 2 is removed from the furnace body 1, the water outlet end of the first tube body 11 is closed, and the water flow loses external power and cannot flow upward. When the outer shell 2 is removed, the water in the second tube body 12 presses the second sealing block 122 downward, so that the second sealing block 122 fits with the second sealing surface 121, thereby blocking the water inlet end of the second tube body 12. For details, refer to Figure 2 .

[0028] In the above embodiment, in order to ensure that the water outlet end of the first tube body 11 is completely closed when the outer shell 2 is removed, an assembly groove 13 is provided on the furnace body 1 to be vertically adapted and plugged with the side wall of the outer shell 2. The depth of the assembly groove 13 is greater than the maximum distance between the bottom wall of the first sealing block 112 and the top wall of the first sealing surface 111 when the water outlet end of the first tube body 11 is open.

[0029] It should be further explained that, during the process of disassembling the outer shell 2, that is, during the process of separating the outer shell 2 from the assembly groove 13, the space of the sealing chamber increases, and the increased space can be used to receive water flowing out of the first tube body 11 and the second tube body 12 before the first sealing block 112 is fitted with the first sealing surface 111 and before the second sealing block 122 is fitted with the second sealing surface 121.

[0030] A drainage hole may also be provided on the bottom wall of the housing 2 .

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
