[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] For the filter in the solenoid valve of the water heater, after long-term use, due to the natural aging of the pipeline or the entry of impurities, more impurity particles will accumulate on the filter, which can easily lead to obstruction of water flow, reduced water volume, and even the water heater cannot be heated. The user or staff dismantles the solenoid valve as a whole and then cleans or replaces the internal filter. This process is rather cumbersome. The following describes a special filter for a solenoid valve provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] In order to solve the problem that the solenoid valve needs to be dismantled as a whole in the prior art to clean the filter, and this process is relatively cumbersome, Figure 1 and Figure 2 as well as Figure 3 As shown, this embodiment proposes a special filter for solenoid valves, which can promptly clean the foreign particles on the filter body 204. The special filter for solenoid valves is composed of an external mechanism 1 as the device body, and a cleaning mechanism 2 is arranged inside the external mechanism 1. The cleaning mechanism 2 can promptly clean the foreign particles on the filter body 204. A collecting mechanism 3 is arranged on the outside of the external mechanism 1. The collecting mechanism 3 is used to collect and clean the foreign particles.

[0025] Since a large amount of impurity particles may accumulate on the filter body 204 in the prior art, which may block the flow of water, a cleaning mechanism 2 is proposed. Two arc collecting covers 206 are provided, and the filter body 204 is installed in the connected inner tube 103. A bearing 201 is fixedly connected to the center of the filter body 204. A fixing rod is fixedly connected to the inside of the bearing 201. Cleaning rods 202 are fixedly connected to both sides of the fixing rod. A connecting rod is fixedly connected to the top of the fixing rod. A turbine blade 203 is fixedly connected to the top of the connecting rod. A plurality of micro-filter holes 205 are provided on the inner tube 103, and the turbine blades 203 are driven to rotate by the release of water flow, so that the connecting rod drives the fixed rod at its bottom to rotate in the bearing 201, so that the two cleaning rods 202 move and clean the impurity particles on the filter body 204, and the impurity particles enter the two arc collecting covers 206 respectively under the action of centrifugal force, so as to clean the impurity particles on the filter body 204, without the need to dismantle and clean the entire solenoid valve, thereby improving the simplicity of the device and ensuring the smooth flow of water.

[0026] The external mechanism 1 is provided with a connecting inner tube 103, and the tops of the two fixing blocks 303 are fixedly connected with a connecting outer ring 101, the inner part of the connecting outer ring 101 is provided with a water inlet pipe 102, and the bottom of the connecting inner tube 103 is provided with a water outlet pipe 104. The device as a whole is connected and fixed to the external pipeline by connecting the outer ring 101, and the water flow direction is ensured by the water inlet pipe 102 and the water outlet pipe 104. The filter body 204 is fixed by connecting the inner tube 103.

[0027] The radius of the cleaning rod 202 is larger than the radius of the connecting inner tube 103 and smaller than the radius of the arc collecting cover 206, thereby ensuring the cleaning effect of the cleaning rod 202 on the impurity particles on the filter body 204 and avoiding obstruction in the rotation process of the cleaning rod 202.

[0028] Embodiment 2:

[0029] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem in the prior art that the user or staff needs to dismantle the entire solenoid valve and then clean the internal filter, which is a relatively cumbersome problem. However, when the impurities on the filter body 204 are cleaned into the two arc collection covers 206, the impurity particles inside the two arc collection covers 206 need to be cleaned regularly to avoid overflow of the impurity particles.

[0030] Since the internal volume of the two arc collecting hoods 206 is limited, the impurity particles collected therein need to be cleaned regularly. Figure 1 and Figure 3 as well as Figure 4As shown, this embodiment proposes a collecting mechanism 3, wherein the collecting mechanism 3 is connected to connecting blocks 301 on both sides of the connecting inner tube 103, and a plurality of through holes a302 are provided on both sides of the two connecting blocks 301, and a fixing block 303 is fixedly connected to the top of the two connecting blocks 301, and two through holes b304 are provided on both sides of the two fixing blocks 303, and a plurality of circular clamping blocks 305 are fixedly connected to both sides of the two arc collecting covers 206, and the aperture sizes of the plurality of through holes a302 and the plurality of through holes b304 are the same, and the plurality of circular clamping blocks 305 can be connected to the plurality of The through holes a302 and the multiple through holes b304 are snap-connected, and the two arc collecting covers 206 can be snap-connected with the connecting block 301 and the fixed block 303 through the multiple through holes a302 and the multiple through holes b304 opened on the connecting block 301 and the fixed block 303, so as to collect the impurity particles cleaned by the cleaning rod 202, and the impurity particles in the two arc collecting covers 206 can be cleaned by separating the multiple circular clamping blocks 305 from the multiple through holes a302 and the multiple through holes b304, thereby ensuring the collection effect of the two arc collecting covers 206.

[0031] Sealing gaskets are installed at the bottom of the connection between the two arc collecting covers 206 and the two connecting blocks 301 and the inner tube 103, so as to prevent leakage of internal water flow at the connection gap.

[0032] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
