[0034] The present invention will be further described below with reference to the accompanying drawings.
[0035] A compact water purifier, such as Figures 1-6As shown, the device includes a frame 1. Near the top of the frame 1 is a water tank receiving cavity 11 for accommodating a hot water tank 2. Near the bottom of the frame 1 is a filter bottle receiving cavity 12 for accommodating a filter element 3. A control panel 4 is located on the front side of the frame 1, and a mounting cavity 13 is opened on the rear side of the frame 1. The mounting cavity 13 contains a water circuit board assembly 131 for mounting a water circuit control element 1313. The water circuit control element 1313 includes multiple solenoid valves and connecting pipes. A first mounting area 101 is formed between the vertical direction of the water tank receiving cavity 11, the horizontal direction of the filter bottle receiving cavity 12, and the vertical direction of the mounting cavity 13. The frame 1 has a first isolation section 14 within the first mounting area 101. The first mounting area 101 is divided into area A and area B by the first isolation section 14. A booster pump 1011 is installed in area A. In some embodiments, a fast-heating module 1012 is installed in region B. In other embodiments, a bubble module 1013 can be installed in region B. When a bubble module 1013 is installed in region B, the fast-heating module 1012 can be installed in the water tap. The system also includes a housing assembly 5, which includes a protective frame 51 and a back plate 52. The protective frame 51 has mounting holes 511 through the front and rear sides of the frame 1. The protective frame 51 is fitted onto the frame 1 through the mounting holes 511, and the front end of the protective frame 51 abuts against the control panel 4. The back plate 52 covers the rear side of the frame 1 and cooperates with the mounting cavity 13, so that the frame 1 can be nested into the mounting holes 511 of the protective frame 51. At the same time, the back plate 52 can protect the water circuit board assembly 131 in the mounting cavity 13 and improve the dustproof and waterproof performance of the water circuit board assembly 131.
[0036] like Figures 2-6As shown, a second installation area 102 is formed by the horizontal direction of the water tank cavity 11, the horizontal direction of the filter bottle cavity 12, and the vertical direction of the control panel 4. A water pump 1021 for drawing water from the hot tank 2 is installed within the second installation area 102 of the frame 1. This effectively utilizes the space between the water tank cavity 11, the filter bottle cavity 12, and the control panel 4, thereby improving the space utilization rate of this invention. A second isolation section 15 is provided within the second installation area 102, dividing the second installation area 102 into area C and area D. The water pump 1021 is installed in area C, and a transformer 1022 is installed in area D. This device utilizes the second isolation section... The separation section 15 divides the second installation area 102 into two parts, so that the water pump 1021 and the transformer 1022 are respectively located in areas C and D of the second installation area 102. This partitioning of multiple functional modules makes the functions of this utility model more modular. The side wall of the frame 1 facing area C is provided with a pump body mounting port 16. The water pump 1021 is fixedly installed on the hot tank 2 through the pump body mounting port 16. The water pump 1021 is set along the vertical direction of the water tank receiving cavity 11. The water pump 1021 is vertically connected to the bottom of the hot tank 2 through the pump body mounting port 16, so that the water pump 1021 is located in the gap space between the water tank receiving cavity 11, the filter bottle receiving cavity 12 and the control panel 4, which can effectively improve the space utilization of this device.
[0037] like Figure 5 As shown, the frame 1 has a pipeline channel 17 connecting the mounting cavity 13 and the first mounting area 101. The pipeline channel 17 allows water pipes and wires to pass through, which helps to constrain the direction of water pipes and wires and to regulate the installation position of water pipes and wires, thereby improving the functional modularity of this utility model. The water circuit board assembly 131 includes a control water circuit board 1311 and a filter element 3 water circuit board 1312. The control circuit board is arranged above the filter element 3 water circuit board 1312, and the pipeline channel 17 is opened between the control water circuit board 1311 and the filter element 3 water circuit board 1312, so that the filter element 3 water circuit board 1312 is arranged close to the filter element 3, while the control water circuit board 1311 is arranged above the filter element 3 water circuit board 1312. This can prevent water droplets from falling onto the control water circuit board 1311 and causing a short circuit when the filter element 3 leaks water accidentally.
[0038] like Figures 3-6As shown, the filter bottle receiving cavity 12 extends horizontally through the front and rear sides of the frame 1, and one end of the filter bottle receiving cavity 12 is connected to the mounting cavity 13, which facilitates the connection of the end of the filter element 3 to the conversion port of the water circuit board assembly 131. The filter bottle receiving cavity 12 is arranged horizontally at the bottom of the frame 1, and the water tank receiving cavity 11 is located above the filter bottle receiving cavity 12. The upper opening of the water tank receiving cavity 11 extends through the upper end face of the frame 1, so that the hot tank 2 can be vertically inserted into the water tank receiving cavity 11, which improves the ease of disassembly and assembly of the hot tank 2. The booster pump 1011 is vertically installed in area A through the positioning seat 18, so that the booster pump 1011 is arranged along the vertical gap direction of area A, which helps to improve the space utilization of this utility model.
[0039] The basic working principle of this utility model is as follows: A water tank receiving cavity 11 is vertically opened at the top of the frame 1, and a filter bottle receiving cavity 12 is horizontally opened at the bottom of the frame 1. A control panel 4 is provided on the front side of the frame 1, and an installation cavity 13 is opened on the rear side of the frame 1. A water circuit board assembly 131 for installing water circuit control element 1313 is provided in the installation cavity 13. This utility model arranges the water tank receiving cavity 11 and the filter bottle receiving cavity 12 in a longitudinal and transverse direction, and sets a first isolation part 14 in the first installation area 101 enclosed between the water tank receiving cavity 11, the filter bottle receiving cavity 12 and the installation cavity 13. The first isolation part 14 is used to isolate the first installation area 101 into area A and area B. At the same time, the booster pump 1011, the fast heating module 1012 or the bubble module 1013 are arranged in the corresponding area A and area B, which makes the overall layout of the water purifier compact and reasonable, which is conducive to reducing the volume of the water purifier and has the effect of improving the structural compactness of the water purifier.
[0040] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
