Embodiment 1

[0025] like figure 1 and figure 2As shown, a diaphragm pump includes a pump body and a water cut-off assembly arranged in the pump body, wherein the pump body includes a pump head body 03, an upper cover 07 and an inner gland-17, and the upper cover 07 is sealed with the top of the pump head body 03 It is connected with the pump head body 03 to form an accommodating cavity. The water cut-off component separates the accommodating cavity to form two upper and lower cavities. The lower cavity is the water passage cavity 10, and the upper cavity is the air pressure cavity 09 , The upper cover 07 forms a vent 06 connecting the air pressure chamber 09 with the outside world. The pump head body 03 of this embodiment is composed of a water inlet 01, a water outlet 14, a sealing sleeve 25, and a water inlet channel 02 and a water inlet channel that are sequentially arranged on the connection channel from the water inlet 01 to the water outlet 14. 22. The low-pressure chamber 21 and ...

Embodiment 2

[0030] like image 3 As shown, the difference between this embodiment and embodiment 1 is: this embodiment uses control two 27 to replace the control rod one 05 in embodiment 1, and adopts air sealing diaphragm two 29 to replace the air sealing diaphragm one 08 in embodiment 1. The structure of the control rod 27 in this embodiment is different from that of the control rod 105. The top plate 23 is formed by the side wall of the control rod 27 protruding outward. Located outside the pump body. In this embodiment, the water inlet 01, water inlet channel 1 02, and water inlet channel 2 22 are not arranged on the pump head body 03, the water inlet 01 is arranged on the top of the control rod 27, the water inlet channel 1 02 and the water inlet channel 2 22 Also be arranged on the control rod two 27. The water inlet chamber in this embodiment is formed by the water inlet chamber 2 28 between the control rod 2 27 , the sealing ring 11 , the water sealing ring 15 , and the inner wa...

Embodiment 3

[0032] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is: this embodiment is not provided with the water passage two 19 described in Embodiment 1, and the control rod one 05 of this embodiment is formed with a water passage three 30, and the water passage three 30 is formed on the control rod one 05 of the present embodiment. The first water chamber 10 and the second water passage 19 are connected through the third water passage 30 , and the lower opening end of the first sealing sleeve 25 of this embodiment is arranged in the low-pressure chamber 21 .

Abstract

The invention discloses a diaphragm pump which comprises a water inlet, a water outlet, a water sealing opening, a low-pressure cavity, a water outlet cavity, a sealing sleeve, a water-break assembly and a water penetration cavity I communicating with the low-pressure cavity, wherein an upper opening end of the sealing sleeve is arranged in the water penetration cavity I; a lower opening end of the sealing sleeve is arranged in the low-pressure cavity or in a water penetration cavity II communicating with the water penetration cavity I; the water-break assembly comprises a control rod and two sealing rings arranged on the control rod in a sleeving manner; the control rod penetrates through the water penetration cavity I, and the lower end of the control rod is embedded in the sealing sleeve; a water inlet cavity is formed among the control rod, the two sealing rings on the control rod and the sealing sleeve; the water sealing opening is formed in the sealing sleeve and is positioned above or below the water inlet cavity; the two sealing rings on the control rod are positioned on the upper side and lower side of the water inlet cavity; the sealing ring, with the water sealing opening, positioned on opposite sides of the water inlet cavity is in close contact with the inner wall of the sealing sleeve; and the sealing ring, with the water sealing opening, positioned on the same side of the water inlet cavity is used for on-off control of the water sealing opening. The diaphragm pump can ensure tight water sealing when the hydraulic pressure of source water is higher and can avoid or reduce vibration.

Description

technical field [0001] The invention relates to a water flow interruption control assembly, in particular to a diaphragm pump. Background technique [0002] Household water purifier systems are usually equipped with water cut-off equipment to control the on-off of the waterway. As one of the many devices that can realize the function of water cut-off, diaphragm pumps are widely used in household pure water machine systems. Existing diaphragm pumps are usually provided with a low-pressure chamber, a water outlet chamber and a water inlet connected to the low-pressure chamber, and a water outlet connected to the water outlet chamber, and a water cut-off assembly for controlling the opening and closing of the water sealing port is provided on the channel connecting the inlet and outlet. When the source water pressure is high, existing diaphragm pumps are prone to problems such as large vibration and poor water sealing at the water sealing port, which to some extent affects the ...
