[0058] Furthermore, a non-negative pressure water supply device 2 is provided on the upper surface of the dual-axis cylinder 11, and a negative pressure eliminator 31 is fixedly installed on the right side of the non-negative pressure water supply device 2. The working principle of the negative pressure eliminator 31 refers to the structural description.

[0060] Furthermore, a water outlet pipe 29 communicating with the non-negative pressure water supply device 2 is fixedly connected to the front surface thereof, and a switch valve is arranged on the water outlet pipe 29 .

[0061] Furthermore, when using the non-negative pressure water supply device with stable water supply, firstly connect the external water pipe to the three external water pipe connectors 14, then pump the external water into the water storage pipe 13, and then input it into the arc-shaped feed box 4 through multiple connecting pipes 12, and then fall into the filter box 3;

[0062] Among them, the external water enters the filter box 3 and passes through the arc filter frame 20. The three oblate filter plates on the arc filter frame 20 will filter the impurities on the external water in turn to prevent a large amount of scale from being easily attached to the inner wall after long-term use, thereby affecting the normal operation of the water supply equipment. By setting three oblate filter plates, the oblate filter plates will filter the external water six times, thereby improving the use efficiency of the arc filter frame 20, and then improving the filtering efficiency of the external water.

[0063] When installing the non-negative pressure water supply device 2, firstly lift the non-negative pressure water supply device 2 by external tools, so that the non-negative pressure water supply device 2 corresponds to the supporting bottom plate 1 up and down, and then turn the non-negative pressure water supply device 2 in the direction;

[0064] The four positioning blocks 24 are inserted into the four mounting grooves 25, and the four support plates 10 are inserted into the four rectangular grooves 23. The four positioning blocks 24 and the four mounting grooves 25 play a positioning role in the installation of the four support plates 10 and the four rectangular grooves 23.

[0067] When installing the filter box 3, the non-negative pressure water supply device 2 has been installed. First, the filter box 3 is lifted by an external tool so that the filter box 3 and the non-negative pressure water supply device 2 are arranged correspondingly up and down, and then the filter box 3 is put down.

[0068] The upper ends of the two L-shaped fixing frames 9 are slid through the upper surfaces of the corresponding mounting plates 5, and the upper end of the connection box 16 is inserted into the interior of the rectangular mounting groove 27.

When the rectangular rubber sealing sleeve 18 contacts the sealing sleeve card groove 28, the rectangular rubber sealing sleeve 18 will be carded into the inner wall of the sealing sleeve card groove 28. The rectangular rubber sealing sleeve 18 and the sealing sleeve card groove 28 will seal the connection between the rectangular mounting groove 27 and the connection box 16, thereby improving the sealing performance of the connection between the rectangular mounting groove 27 and the connection box 16.

[0069] The filter box 3 as a whole continues to move downward, so that the first support sleeve 15 contacts the upper surface of the filter box 3 and the two mounting plates 5 contact the upper surfaces of the corresponding second support sleeves 19. The first support sleeve 15 and the second support sleeve 19 not only support the filter box 3 as a whole, but also position the installation of the filter box 3 as a whole.

[0070] Among them, four lifting cylinders 8 are then activated, and the telescopic ends of the four lifting cylinders 8 push the two electromagnets 7 to move downward, so that the two electromagnets 7 correspond to the corresponding fixed iron plates 6 respectively, and then the two electromagnets 7 are started to adsorb the corresponding fixed iron plates 6, thereby fixing the filter box 3 as a whole.

[0071] Structure Description:

[0072] Negative pressure eliminator 31: The negative pressure eliminator is mainly composed of a float, a valve and other components. When the water level in the non-negative pressure regulating tank rises, the float rises accordingly. When the water level drops, the float drops. The vertical up and down movement of the float controls the opening and closing of the valve. When the float rises, the valve may close or reduce the opening to reduce the discharge of gas in the tank. When the float drops, the valve may open or increase the opening to allow more gas to enter the tank, thereby breaking the vacuum environment that may be formed. The negative pressure eliminator suppresses and eliminates the vacuum in the tank through the coordinated work of the float and the valve. When a negative pressure trend appears in the tank, the negative pressure eliminator will adjust the valve opening in time to allow gas to enter the tank, thereby avoiding the generation of negative pressure.

[0073] The oblate filter plate frame 20 is composed of three oblate filter plates, which are fixedly connected together by a fixing plate. The three oblate filter plates are, from the inside to the outside, an activated carbon filter, a medium-efficiency filter and a PP cotton filter.

[0080] Electromagnet 7: The electromagnet 7 is arranged on the lifting cylinder 8, and the electromagnet 7 cooperates with the fixing iron plate 6 to fix the mounting plate 5.

[0081] Rectangular rubber sealing sleeve 18 : The rectangular rubber sealing sleeve 18 is arranged on the connection box 16 , and the rectangular rubber sealing sleeve 18 cooperates with the sealing sleeve slot 28 to seal the connection between the connection box 16 and the rectangular installation slot 27 .
