Description

Filter core and locking and take-out device of filter core Technical Field The application relates to the field of filter devices, in particular to a filter element and a locking and taking-out device of the filter element. Background The water purifier is water purifying equipment for purifying water by adopting the multi-stage filter element, and can effectively filter inorganic salt, organic bacteria and the like in water. When the filter element is dismounted by most water purifiers, the filter element needs to be dismounted along the length direction of the filter element, so that a larger filter element dismounting space needs to be reserved on the front side of the position of the water purifier, which is used for mounting the filter element. When the water purifier is used in the market, most of the water purifier is installed in a small space such as a kitchen, so that the direction and the space for taking out the filter element are greatly limited. If the filter element is taken out of the machine, the connected pipeline is pulled or even displaced, so that the machine is installed back, and the problems of water leakage, pipeline bending and the like can occur. Disclosure of Invention The application provides a filter element and a locking and taking-out device of the filter element, in order to improve the convenience of replacing the filter element in a narrow space. The application provides a locking and taking-out device of a filter element, which adopts the following technical scheme: The utility model provides a locking and take-out device of filter core, includes frame, locking mechanical system and ejection mechanism, set up the filter core chamber on the frame, the filter core chamber is equipped with the opening, just the filter core chamber is used for supplying the filter core body to pack into along the direction that staggers with filter core body length direction, locking mechanical system is used for restricting the filter core body and shifts out the filter core chamber, ejection mechanism is used for ejecting the filter core body out the filter core chamber. Through adopting above-mentioned technical scheme, when changing the filter core, remove locking mechanical system earlier and to the restriction of filter core body, then the ejecting mechanism is ejecting the filter core chamber of filter core body with the filter core body again, takes out the filter core body along the direction of staggering with filter core body length direction at last. When the filter element body is installed, the filter element body is installed in the filter element cavity along the direction staggered with the length direction of the filter element body, and the optimal mode is that the filter element body is installed in the filter element cavity along the direction perpendicular to the length direction of the filter element body, and then the filter element is locked through the locking mechanism. The filter element is replaced in this way, the first aspect is provided with the filter element cavity, the disassembly and assembly direction of the filter element body is staggered from the length direction of the filter element body, the space required by disassembly and assembly of the filter element body is effectively reduced, and the second aspect is provided with the ejection mechanism for ejecting the filter element, so that the convenience of replacing the filter element body in a narrow space is further improved compared with the process of buckling the filter element body. Optionally, the locking mechanism is slidingly disposed on the frame, and the sliding direction of the locking mechanism is staggered from the direction in which the filter element body is installed in the filter element cavity, and the locking mechanism includes a latch, and the latch is used for being inserted into a slot on the filter element body. By adopting the technical scheme, when the filter element body arranged in the filter element cavity is locked, the locking mechanism enables the bolt to be inserted into the slot on the filter element body. Because the sliding direction of the locking mechanism is staggered with the direction of the filter element body, the plug pin inserted into the slot on the filter element body along the sliding direction of the locking mechanism can effectively limit the filter element body to move out of the filter element cavity, and the locking mechanism is simple and reliable in structure and convenient to operate. Optionally, the locking mechanism further comprises a guide rail connected to the plug pin, a guide groove is formed in the frame, and the guide rail is slidably arranged in the guide groove. By adopting the technical scheme, the guide rail is arranged in the guide groove in a sliding way, the sliding stability of the plug pin can be improved on the first aspect, the plug pin can be inserted into the slot, and the matching of the guide rail and the guide groove and th
