Embodiment 1

[0022] The present invention is used for the structure of water plug and water socket on household water purifying equipment such as figure 1 As shown, the structure of the water plug is as follows figure 2 As shown, the water plug 3 includes a lower cover 34, an upper cover 32 fastened on the lower cover 34 and a plug outer tube 33 arranged between the upper cover 32 and the lower cover 34. After the upper cover 32 and the lower cover 34 are engaged An accommodating space for installing the plug outer tube 33 is formed inside, and one end of the plug outer tube 33 is connected to a water pipe through a pipe joint nut 4 or a quick connector. Wherein, the plug outer tube 33 is integrally formed with a positioning block 331 , and both the upper cover 32 and the lower cover 34 are provided with a positioning groove 39 for fixing the positioning block 331 .

[0023] Wherein, there are two plug outer tubes 33, one of which is the water inlet plug outer tube, and the other plug ou...

Embodiment 2

[0030] Embodiment 2 adds a one-way control device on the basis of embodiment 1. The one-way control device includes a one-way valve 35 installed in the outer tube 33 of the plug, a spring 36 sleeved outside the one-way valve 35 and a Position the plug 31 of the one-way valve 35 , the plug 31 is fixedly installed at the port of the plug outer tube 33 , one end of the spring 36 abuts against the one-way valve 35 , and the other end abuts against the plug outer tube 33 . The setting of the one-way control device prevents the water flow in the water pipe from flowing out when the water plug is pulled out from the water socket, which affects the use environment of the household water purification equipment.

[0031] A sealing ring 37 is arranged between the plug 31 and the plug outer tube 33 to prevent water from seeping out at the connection between the plug and the plug outer tube, which will affect the use environment of the household water purification equipment.

Embodiment 3

[0033] Embodiment 3 adds an anti-loosening device on the basis of Embodiment 1 or Embodiment 2. The anti-loosening device includes a card slot 321 provided on the upper cover 32 of the water plug 3 and a locking groove 321 provided on the base body 22 of the water socket 2. The anti-loosening elastic piece 23 is provided with a buckle that can be inserted into the locking groove 321 . The setting of the anti-loosening device can prevent the water socket from being separated due to high water pressure, and further improve the safety of use.

[0034] When you need to remove the water plug, you only need to pull out the anti-loose shrapnel first, and then pull out the water plug; when you need to connect the pipeline, insert the plug outer tube in the water plug into the seat along the plug inner tube on the water socket until The buckle is completely snapped into the card slot.

Abstract

The invention discloses a water plug and a water socket both used on household water-purifying equipment. The water plug comprises a lower cover, an upper cover buckled on the lower cover, and plug outer pipes arranged between the upper cover and the lower cover, a containing space allowing the plug outer pipes to be mounted is formed inside after the upper cover is buckled with the lower cover, one ends of the plug outer pipes are connected with water pipes through pipe joint nuts or quick joints, the water socket is used for being connected with the water plug and comprises a seat body fixedly mounted on a main unit of the household water-purifying equipment, and plug inner pipes integrally formed on the seat body and connected with a filter in the main unit of the household water-purifying equipment, and the plug inner pipes can be inserted into the plug outer pipes. A structure that the water plug and the water socket are in matched connection is adopted, so that more convenience is brought to pipeline connection of the household water-purifying equipment, and no professional is needed for mounting or on-site guiding; a one-way control device is arranged on the water plug, so that overflowing of water in the water pipe is avoided when the water plug is plugged out from the water socket.

Description

technical field [0001] The invention relates to the field of household water purification equipment, in particular to a water plug and a water socket used for household water purification equipment. Background technique [0002] Household water purification equipment is the equipment used to produce clean water in the family. Due to factors such as long-term disrepair of the pipeline, the tap water for daily drinking will cause secondary pollution, which will affect the health of users. Therefore, water purification equipment is very popular among people. favorite. However, the inlet and outlet pipes of existing household water purification equipment are respectively arranged at both ends of the water purification equipment, and pipe joints are used to connect the water pipes. The installation and disassembly are complicated, and professional after-sales personnel are required to install and disassemble or on-site guidance. Contents of the invention [0003] (1) Technical...
