Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a filter bottle structure for water purification equipment which is easy to replace. Background Art

[0002] Water purifier is a commonly used water purification equipment. In order to improve the water purification effect of the water purifier, some water purifiers use multiple filter elements at the same time to purify the water flow multiple times. Different filter elements are set in different filter cartridges. After working for a period of time, it is necessary to stop the water supply and remove the filter cartridge for cleaning or replacement.

[0003] According to the patent website, a water purification device for easy replacement of filter cartridges (authorization announcement CN 212383293U) is described as follows: "A water purification device for easy replacement of filter cartridges includes a water pipe, a filter cartridge, a water inlet pipe, a water outlet pipe, a fixing platform, a box body and a spring sealing mechanism. A plurality of filter cartridge jacks are provided at the lower end of the water pipe. The spring sealing mechanism includes a sealing cover plate, a connecting short rod, a push plate, a telescopic rod and a compression spring. The sealing cover plate is fixedly connected to the bottom end of the connecting short rod, the connecting short rod is connected to the fixing platform through, the bottom end of the telescopic rod is fixedly connected to the push plate, and the top end is fixedly connected to the top surface inside the box body. The compression spring is sleeved on the telescopic rod, and the upper and lower parts of the compression spring are respectively fixedly connected to the top surface inside the box body and the upper end of the push plate. The water inlet pipe and the water outlet pipe are respectively connected to the two ends of the water pipe."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] The utility model discloses that when the filter cartridge is removed, the filter cartridge hole can be automatically sealed by arranging a spring sealing mechanism with an automatic sealing function in the water pipe, so as to prevent water from leaking out of the filter cartridge hole. However, in actual use, the device drives the sealing plate through the spring, and can complete the sealing of the filter cartridge hole under the action of the spring, so as to prevent water from leaking out of the filter cartridge hole. When the filter cartridge is subsequently installed, it is easy for the filter cartridge to be inserted into the device and be easily pushed by the spring. Since there is no secondary fixing device, the filter cartridge can be easily separated from the device, which can easily lead to the filter cartridge being not firmly fixed, resulting in poor sealing of the filter cartridge, and thus easily causing water to leak out of the filter cartridge connection. Therefore, it is necessary to improve a filter bottle structure for water purification equipment that is easy to replace. Utility Model Content
