Description

Technical Field

[0001] This application relates to the field of instant hot water dispenser technology, specifically to an instant hot water dispenser with an easy-to-replace filter cartridge. Background Technology

[0002] In today's diverse settings such as homes, offices, small shops, apartments, and school dormitories, instant hot water purifiers are gradually becoming important devices for meeting daily drinking water needs due to their core advantages of "instant filtration and heating, no waiting". These devices integrate water purification and instant heating functions, effectively solving the pain points of traditional water purifiers requiring a kettle and traditional water dispensers lacking purification capabilities. Their market acceptance is gradually increasing. However, existing instant hot water purifiers still have many issues that need to be optimized during long-term use, among which the inconvenience of filter replacement is particularly prominent.

[0003] Application number CN202222970771.6 discloses a replaceable water dispenser filter element, comprising a water dispenser body, an operation box fixedly connected to the right side of the water dispenser body, a drive motor fixedly connected to the inner bottom wall of the operation box, a threaded screw fixedly connected to the output end of the drive motor, a sealed bearing fixedly embedded in the inner top wall of the operation box, the top end of the threaded screw being fixedly connected to the inner ring of the sealed bearing, and a threaded sleeve plate being threadedly connected to the outer surface of the threaded screw.

[0004] However, most instant water dispensers currently use electrical circuits to facilitate water circulation and heating. The drawback is that in the event of a power outage, circuit failure, or a damaged control button, the instant water dispenser's power supply function will fail. The aforementioned easily replaceable water dispenser filter has certain shortcomings. In cases of motor failure, power outages, circuit failures, or damaged control buttons, the motor cannot receive power, preventing the installation cylinder lifting function from starting. Consequently, the filter cannot be removed and replaced, affecting the convenience of daily drinking water.

[0005] Therefore, it is necessary to provide a water purifier with an easy-to-replace filter to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a water purifier with an easy-to-replace filter element, which solves the problem that when there is a power outage, power failure or circuit failure in the living area, the motor cannot be powered, resulting in the inability to start the lifting function of the installation cylinder, making it impossible to disassemble and replace the filter element, thus affecting the convenience of daily drinking water.

[0008] The technical solution adopted by this application to solve its technical problem is: a water purifier with easy filter replacement, including an instant water purifier body, a positioning component provided on the instant water purifier body, a positioning block connected to the inner side of the instant water purifier body, a filter frame rotatably connected to the surface of the positioning block, a filter element body connected to the inner side of the filter frame, splicing plates connected to both sides of the filter element body, and a sealing cap snapped onto the top of the instant water purifier body, with two fastening bolts threaded onto the inner side of the sealing cap. The surface of the positioning component is connected to the inside of the instant hot water dispenser body to provide a positioning force for the filter frame.

[0009] Furthermore, the positioning assembly includes two fixed frames, two connecting plates, and four composite contraction springs. Both fixed frames are located inside the body of the instant hot water dispenser. Two positioning slide rods are slidably connected to the inner top of each of the two fixed frames. A wedge-shaped locking plate is connected to the bottom end of each pair of positioning slide rods. The bottom end of each connecting plate is connected to the top end of each pair of positioning slide rods. The four composite contraction springs are respectively sleeved on the outer side of the four positioning slide rods. Limiting grooves are formed on the inner side of each of the two fixed frames.

[0010] Furthermore, the surfaces of both fixed frames are in contact with the surface of the filter frame.

[0011] Furthermore, the surfaces of the two wedge-shaped plates are respectively engaged and connected to the inner sides of the two splicing plates.

[0012] Furthermore, the two ends of each pair of composite contraction springs are respectively connected to the top end of each fixed frame and the bottom end of each connecting plate.

[0013] Furthermore, the surfaces of the two splicing plates are slidably attached to the inner sides of the two limiting grooves, respectively.

[0014] Furthermore, the surfaces of both fastening bolts are threadedly connected to the inner top of the instant hot water dispenser body.

[0015] The beneficial effects of this application are as follows: This application provides a water purifier with an easy-to-replace filter element for instant hot water. The positioning block facilitates the positioning of the filter frame. The sliding action of the positioning slide rod and the contraction action of the composite contraction spring facilitate the upward or downward movement of the wedge-shaped plate. By moving the wedge-shaped plate upward and separating it from the splicing plate, the filter element body can be easily removed for replacement. By allowing the wedge-shaped plate to elastically move downward and engage with the splicing plate, the filter element body can be limited, preventing displacement of the filter element body during use. Even in the event of a power outage, the installation and removal of the filter element body can be easily and quickly achieved, making the operation simple.

Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figure 1-4As shown, this application provides a water purifier with an easy-to-replace filter cartridge, including an instant water purifier body 1, a positioning component 2 on the instant water purifier body 1, a positioning block 3 connected to the inner side of the instant water purifier body 1, a filter frame 4 rotatably connected to the surface of the positioning block 3 to provide support for the filter cartridge body 5, the filter cartridge body 5 connected to the inner side of the filter frame 4 to facilitate filtering of the water source, splicing plates 6 connected to both sides of the filter cartridge body 5, and a sealing cover 7 snapped onto the top of the instant water purifier body 1, with two fastening bolts 8 threaded onto the inner side of the sealing cover 7 to facilitate fixing the sealing cover 7; The surface of the positioning component 2 is connected to the inside of the instant hot water dispenser body 1 to provide positioning force for the filter frame 4.

[0021] The positioning component 2 includes two fixed frames 21, two connecting plates 24, and four composite contraction springs 25. The two fixed frames 21 are both located inside the body 1 of the instant hot water dispenser. Two positioning slide rods 22 are slidably connected to the inner top of each of the two fixed frames 21. A wedge-shaped card plate 23 is connected to the bottom of each pair of positioning slide rods 22. The unique shape of the wedge-shaped card plate 23 makes it easier to position the filter core body 5. The bottom of each connecting plate 24 is connected to the top of each pair of positioning slide rods 22. The four composite contraction springs 25 are respectively sleeved on the outer side of the four positioning slide rods 22. Limiting grooves 26 are opened on the inner side of each of the two fixed frames 21 to provide limiting force for the splicing plate 6.

[0022] The surfaces of both fixed frames 21 are in contact with the surface of the filter frame 4, and the surface of the filter frame 4 is adapted to the surface shape of the fixed frames 21, which helps to improve the stability of the positioning of the filter frame 4.

[0023] The surfaces of the two wedge-shaped clamping plates 23 are respectively engaged with the inner sides of the two splicing plates 6, which helps to limit the splicing plates 6 and prevent them from shifting randomly.

[0024] The two ends of each pair of composite contraction springs 25 are connected to the top of each fixed frame 21 and the bottom of each connecting plate 24, respectively, providing an elastic downward pressing force for the wedge-shaped clamping plate 23 to improve the stability of the positioning of the splicing plate 6.

[0025] The surfaces of the two splicing plates 6 slide against the inner sides of the two limiting slide grooves 26 respectively, so that the splicing plates 6 can be rotated into the limiting slide grooves 26 for installation and removal of the filter element body 5.

[0026] The surfaces of the two fastening bolts 8 are threaded to the inner top of the instant hot water dispenser body 1, which facilitates the improvement of the stability of the sealing cover 7.

[0027] Working principle: First, when the filter element body 5 needs to be replaced, remove the two fastening bolts 8 and remove the sealing cover 7 from the instant hot water dispenser body 1. Then, pull up the two connecting plates 24. Under the sliding action of the four positioning slide rods 22, the two wedge-shaped clamping plates 23 will move upward, thereby separating the two wedge-shaped clamping plates 23 from the inside of the splicing plate 6. Then, rotate the filter frame 4 as a whole 90° to the left or 90° to the right. At this time, the two splicing plates 6 will separate from the two limiting slide grooves 26. The filter frame 4 can be easily and quickly removed from the instant hot water dispenser body. The filter element body 5 is removed from the upper part of the filter body 1 to replace it. Similarly, when replacing the filter element body 5, the filter frame 4 is inserted into the positioning block 3, and then the two connecting plates 24 are pulled upward. After that, the filter frame 4 is rotated to slide the splicing plate 6 into the limiting groove 26. Then, the two connecting plates 24 are released. Under the contraction action of the composite contraction spring 25, the two wedge-shaped clamping plates 23 will be driven downward into the two splicing plates 6 to fix the position of the filter frame 4. This makes it easy to disassemble the filter element body 5 and also easy to install and replace it.

[0028] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
