[0070] The water system, such as a whole house water purification system, is usually provided with a pre-filter, and the pre-filter is used to filter large particles in tap water, which can not only guarantee the water safety of residents, but also prolong the service life of household appliances, prevent household water pipes from being blocked, and improve the health level of residents. The pre-filter is the first rough filtration equipment of the whole house water purification system, and belongs to a physical filtration equipment, which is mainly used for intercepting large particles above 40 microns to protect the safety of the rear water.

[0071] The pre-filter has a filtration mode and a flushing mode, in the filtration mode, the pre-filter can filter large particles, and in the flushing mode, the pre-filter can clean the filter assembly 16 inside to discharge the large particles intercepted before, so that the pre-filter does not need to be manually disassembled and cleaned, and the service life of the pre-filter is improved.

[0072] Please refer to Figures 1 to 4 In an embodiment of the present application, the pre-filter comprises:

[0073] The filter body 1 has a sewage discharge end 11, and the sewage discharge end 11 is provided with a sewage discharge valve 111.

[0074] The electric sewage discharge assembly 2 is arranged at the sewage discharge end 11, and the electric sewage discharge assembly 2 comprises a housing 21, a drive module 22, an electric control module 23 and a power module 24 arranged in the housing 21, the drive module 22 is drivingly connected to the sewage discharge valve 111, the electric control module 23 is electrically connected to the power module 24, the drive module 22 is electrically connected to the electric control module 23, and the drive module 22, the electric control module 23 and the power module 24 are arranged on different sides of the sewage discharge end 11.

[0075] Specifically, the sewage discharge end 11 is used to discharge the cleaned sewage, and the sewage discharge valve 111 is used to control the opening and closing of the sewage discharge end 11. The electric sewage discharge assembly 2 is arranged at the sewage discharge end 11, and the electric sewage discharge assembly 2 comprises the drive module 22, the drive module 22 is drivingly connected to the sewage discharge valve 111, so as to realize the automatic flushing of the pre-filter, thereby facilitating the user operation, and reducing the situation that the filter screen is blocked due to the user forgetting to flush.

[0076] The electric control module 23 is electrically connected to the power supply module 24, and the driving module 22 is electrically connected to the electric control module 23, so that the power supply module 24 can supply power to the electric control module 23 and the driving module 22, and the electric control module 23 can control the driving module 22 to work, thereby controlling the switching of the pre-filter in different modes. However, in the prior art, the positions of the driving module 22, the electric control module 23 and the power supply module 24 are often not reasonable enough, which may cause the size of the electrically-driven blowdown assembly 2 in a certain direction to be larger, thereby causing the limit size of the electrically-driven blowdown assembly 2 to be larger, and also causing the installation space required by the pre-filter to be larger. However, the pre-filter is often installed in the under-cook space, and the installation space is limited. Therefore, it is difficult to install the pre-filter, and even it cannot be installed.

[0077] Therefore, in the embodiment, the driving module 22, the electric control module 23 and the power supply module 24 are arranged on different sides of the blowdown end 11, that is, the driving module 22, the electric control module 23 and the power supply module 24 are arranged around the periphery of the blowdown end 11, so as to avoid at least two of the driving module 22, the electric control module 23 and the power supply module 24 being arranged on the same side of the blowdown end 11, thereby reducing the possibility that the size of one side of the blowdown end 11 is larger due to the stacking of different modules. Therefore, the electrically-driven blowdown assembly 2 is arranged in a nearly square shape, so that the size of the electrically-driven blowdown assembly 2 in each direction is balanced, thereby improving the rationality of the arrangement of the driving module 22, the electric control module 23 and the power supply module 24, and reducing the problem of the size of the electrically-driven blowdown assembly 2 being too large in a single direction.

[0078] In the embodiment, the electrically-driven blowdown assembly 2 is arranged in a nearly rectangular shape. In other embodiments, the electrically-driven blowdown assembly 2 can also be in the form of a multi-prism, such as a three-prism.

[0079] Further, the driving module 22, the power supply module 24 and the electric control module 23 are arranged in sequence along the circumference of the blowdown end 11, and the driving module 22 and the power supply module 24 are arranged opposite to each other. Specifically, the side where the electric control module 23 is arranged is usually normal to the electrically-driven blowdown assembly 2, thereby facilitating user operation. Correspondingly, the power supply module 24 and the driving module 22 are arranged opposite to each other, that is, the driving module 22 is arranged on the back of the electrically-driven blowdown assembly 2. Since the driving module 22 is mainly used to drive the movement of the blowdown valve 111, it is not involved in user operation, and therefore is arranged on the back. The power supply module 24 is arranged between the driving module 22 and the electric control module 23, and is arranged on the side of the electrically-driven blowdown assembly 2, thereby facilitating the user to replace or charge the battery power supply 25.

[0080] Please refer to Figures 4 to 8In the embodiment of the present application, the driving module 22 comprises a driving motor 221, one of the blowdown valve 111 and the driving motor 221 is provided with a transmission shaft 112, and the other is provided with a limiting groove 222, and the transmission shaft 112 is inserted into the limiting groove 222. Specifically, the driving motor 221 can drive the blowdown valve 111 to rotate, so as to realize the opening and closing of the blowdown end 11. The blowdown valve 111 and the driving motor 221 are connected through the transmission shaft 112 and the limiting groove 222 to realize the transmission connection of the two, that is, the driving motor 221 and the blowdown valve 111 are directly connected in transmission, compared with the prior art, the driving motor 221 and the blowdown valve 111 are connected in transmission through a shaft coupling and the like, the present scheme is helpful to further reduce the occupied space of the driving module 22, so as to reduce the overall volume of the electric blowdown assembly 2. In the present scheme, the transmission shaft 112 is arranged on the blowdown valve 111 and protrudes from the side of the blowdown end 11, and the limiting groove 222 is arranged on the driving motor 221, so that the transmission of the driving motor 221 and the blowdown valve 111 is matched outside the blowdown end 11, thereby reducing the sealing difficulty at the transmission shaft 112. Of course, in other embodiments, the transmission shaft 112 can also be arranged on the driving motor 221, and the limiting groove 222 is correspondingly arranged on the blowdown valve 111, and the transmission shaft 112 extends into the blowdown end 11 to be inserted into the limiting groove 222.

[0081] In order to facilitate the installation of the driving motor 221, in an embodiment, the driving module 22 further comprises a mounting plate 223, the mounting plate 223 is assembled on the blowdown end 11, the driving motor 221 is assembled on the side of the mounting plate 223 away from the blowdown end 11, and the transmission shaft 112 passes through the mounting plate 223 and is inserted into the limiting groove 222. Specifically, the mounting plate 223 is fixed on the blowdown end 11, and the driving motor 221 is fixed on the side of the mounting plate 223 away from the blowdown end 11, so that the driving motor 221 is hung on the blowdown end 11 through the mounting plate 223, avoiding that the driving motor 221 is only fixed between the blowdown end 11 through the connection between the transmission shaft 112 and the limiting groove 222, so as to ensure the stable fixation of the driving motor 221. Referring to Figure 7 and Figure 8For the convenience of the installation of the plate 223, the one side of the blowdown end 11 is provided with a mounting portion 113, the plate 223 is in abutment with the mounting portion 113, and the plate 223 is provided with a second mounting hole 2232, and the first fastener is fastened and connected to the mounting portion 113 through the second mounting hole 2232, that is, the plate 223 is connected with the mounting portion 113 by screw locking, so that the installation of the plate 223 is convenient, and the stability of the installation is ensured. Similarly, the plate 223 is also provided with a first mounting hole 2231, and the second fastener is fastened and connected to the driving motor 221 through the first mounting hole 2231, that is, the plate 223 is also connected with the driving motor 221 by screw locking, so that the installation of the driving motor 221 is convenient, and the stability of the installation is ensured. In the present scheme, the first mounting hole 2231 is arranged at four corners of the plate 223, so that the stability of the fixing of the driving motor 221 is further ensured.

[0082] Further, the inner side of the shell 21 is provided with a limiting rib 211, and the limiting rib 211 is in abutment with the side of the driving motor 221 away from the blowdown valve 111; specifically, the existence of the limiting rib 211 can facilitate the abutment of the shell 21 and the driving motor 221, so as to reduce the possibility of vibration and abnormal sound of the driving motor 221 in the shell 21.

[0083] Further, part of the shell 21 is outwardly raised to form a first mounting groove 212, and the driving motor 221 is at least partially arranged in the first mounting groove 212. Specifically, that is, the first mounting groove 212 of the shell 21 is realized by the partial outward raising of the shell 21, so as to further increase the mounting space of the driving motor 221 in the shell 21, and to help further control the overall volume of the shell 21.

[0084] In an embodiment of the present application, please refer to Figures 15 to 19 The power supply module 24 is provided with a battery box 242 for installing a power supply battery, the shell 21 is provided with an opening 2411 downward battery compartment 241, the battery box 242 is slidingly inserted into the battery compartment 241, and the battery box 242 and the battery compartment 241 are provided with a press switch 243; the battery box 242 is pressed into the battery compartment 241, which can open the press switch 243, so that the battery box 242 is separated from the battery compartment 241.

[0085] Specifically, since the pre-filter is generally arranged in the under-cook space, the installation space is small, and it is not convenient to replace or dismount the power battery for charging, therefore, the battery box 242 in the present scheme can be dismounted, thereby facilitating the dismounting or replacement of the power battery. In the present scheme, the battery compartment 241 is fixed in the shell 21, and is used for mounting the battery box 242, thereby facilitating the dismounting of the battery box 242. The opening 2411 of the battery compartment 241 is arranged downward, since the pre-filter is generally arranged in the under-cook space, therefore, the bottom has sufficient space for taking out the battery box 242, and the battery box 242 is taken out from the side, thereby avoiding occupying unnecessary installation space. The press switch 243 is arranged between the battery box 242 and the battery compartment 241, the press switch 243 can connect the battery box 242 and the battery compartment 241, thereby enabling the battery box 242 to be stably arranged in the battery compartment 241, and then pressing the battery box 242 in the direction of the battery compartment 241 can open the press switch 243, thereby enabling the battery box 242 to be taken out of the battery compartment 241, thereby facilitating the taking out of the battery box 242.

[0086] Further, referring to Figure 17 and Figure 18 , the press switch 243 comprises a connecting hook 2431 arranged on the battery box 242, and an elastic clamping piece 2432 arranged in the battery compartment 241, the elastic clamping piece 2432 can be hung on the connecting hook 2431, and the elastic clamping piece 2432 has a tendency to clamp the connecting hook 2431; pressing the battery box 242 in the battery compartment 241 can enable the elastic clamping piece 2432 to be opened, thereby enabling the connecting hook 2431 to be taken out of the elastic clamping piece 2432. Specifically, the elastic clamping piece 2432 comprises two clamping portions arranged at an angle, the two clamping portions can swing relative to each other, thereby adjusting the opening angle of the elastic clamping piece 2432, and the side close to the battery box 242 of the two clamping portions is provided with a hook portion, the hook portion can be hung on the connecting hook 2431, thereby ensuring that the battery box 242 is stably arranged in the battery compartment 241 and will not be accidentally taken out. When the battery is mounted in the battery compartment, the connecting hook 2431 is in contact with the elastic clamping piece 2432, and continues to move inward, thereby pushing the elastic clamping piece 2432, so that the elastic clamping piece 2432 can be hung on the connecting hook 2431, thereby ensuring the stable fixation of the battery box 242. Continuing to press the battery box 242 in the battery compartment 241 can enable the elastic clamping piece 2432 to be further opened and kept in the opened state, thereby enabling the connecting hook 2431 to be taken out of the elastic clamping piece 2432, so that the battery box 242 is taken out of the battery compartment 241. When the battery box 242 is mounted again, when the battery box 242 is completely arranged in the battery compartment 242, the connecting hook 2431 can release the limiting of the elastic clamping piece 2432, so that the elastic clamping piece 2432 can move freely, thereby enabling the elastic clamping piece 2432 to clamp the connecting hook 2431 again.
