One embodiment is described below.

A lower-positioned water dispenser 2 comprises a machine body 22, a water barrel 21 and a connecting pipe component 1.

The body 22 includes a middle tray 226, a lower cabinet 227, and a tray 228. The middle support 226 is provided with a guide sleeve 222, a slot 2221 is formed in the side wall of the guide sleeve 222, and a quick connector 221 is arranged above the guide sleeve 222. The water outlet of the water dispenser 2 is positioned above the middle support 226, and the quick connector 221 is used for butting the connecting pipe assembly 1. The lower cabinet 227 defines a receiving cavity 225, and the tray 228 is located at the bottom of the receiving cavity 225. The accommodating chamber 225 is for accommodating the water tub 21, the tray 228 is for supporting the water tub 21, and the tray 228 is adapted to slide relative to the lower cabinet 227 so that the water tub 21 can be located in the accommodating chamber 225 or withdrawn from the accommodating chamber 225, as shown in fig. 11 and 10. A water suction cover 211 is covered on the opening of the water bucket 21, the water suction cover 211 is provided with a water suction connector 212, and the water suction connector 212 is provided with a clamping hole 2121 (also called a reverse buckling groove) for butting the connecting pipe assembly 1, so that the water in the water bucket 21 can be conveyed upwards through the connecting pipe assembly 1.

The joint pipe assembly 1 includes a metal hose body 11, a first joint 12, and a second joint 13. The metal hose body 11 is a stainless steel universal pipe, two ends of the metal hose body are respectively connected with the first joint 12 and the second joint 13, and the first joint 12 and the second joint 13 are respectively and quickly connected with the water absorption cover 211 of the water bucket 21 and the machine body 22. The first connector 12 is a quick connector and the second connector 13 is a bayonet connector. The two ends of the universal pipe are fixedly connected with the inserted link joint and the quick connector into a whole in an adhesive mode.

Wherein the bayonet joint is inserted into the guide sleeve 222 of the bracket 226 of the water dispenser 2. The bayonet joint comprises a third connecting pipe section 131 and a fourth connecting pipe section 132, the fourth connecting pipe section 132 being connected to a quick coupling 221 in the fuselage 22. The side wall of the guiding sleeve 222 is provided with a slot 2221, and the rod connector is fixed on the middle bracket 226 by a connecting piece 223. The connecting member 223 is a bayonet lock, and includes two elastic buckles 2231 and a combining portion 2232, and the combining portion 2232 may further include a push-pull portion 2233 for facilitating pushing and pulling the bayonet lock. The two elastic buckles 2231 are clamped at the two clamping grooves 2221 and support the third connecting pipe section 131 of the plunger joint to prevent the plunger joint from falling off.

The quick connector is connected with the water absorption cover 211 of the water bucket 21 and is fixed with a clamping hole 2121 (or a reverse buckling groove) of the water absorption cover 211 through a clamping hook 123. The quick connector is provided with an elastic handle 124, and when the handle is pressed down, the hook 123 of the handle is separated from the clamping hole 2121 (or the reverse buckling groove) of the water absorption cover 211, so that the quick connector can be pulled out. When the barrel is replaced, the water barrel 21 can be pulled out of the machine body 22 or not (depending on the size of the operation space of the lower cabinet 227), the quick-connection plug is pressed by fingers, the clamping hook 123 of the quick-connection plug is pulled out of the clamping hole 2121 of the water absorption cover 211, meanwhile, the quick-connection plug is pulled out to be separated from the water absorption cover 211, and then the barrel replacement operation is carried out. Of course, if the universal pipe is long enough, it is not necessary to separate the quick connector from the water absorption cover 211, but the water absorption cover 211 is directly extracted and then the barrel replacement operation is performed.

Because the stainless steel universal pipe has the characteristics of being bent at any angle and being watertight, the problem that the original connecting pipe of the water dispenser 2 and the water suction cover 211 of the water barrel 21 absorbs peculiar smell and is aged to influence the water quality can be solved. Meanwhile, the inserted link joint connected with the body 22 can rotate relative to the guide sleeve 222 of the centering bracket 226 along with the movement of the stainless steel universal pipe, so that the water bucket 21 can be pushed in and pulled out during bucket replacement, and replacement operation of water buckets 21 of different specifications is facilitated. Moreover, the universal pipe can be set to be a proper length, and the universal pipe can be suitable for connecting the buckets 21 with different heights through the bending characteristic of the universal pipe.

To sum up, the connecting tube subassembly and the water dispenser that this application provided adopt the metal collapsible tube body, and metal collapsible tube compares in silica gel hose and plastic hose, has that chemical stability is strong, corrosion-resistant, ageing-resistant advantage to can prevent to produce the peculiar smell, take place ageing and influence quality of water, be favorable to guaranteeing the quality of water dispenser. Simultaneously, the both ends of metal collapsible tube body are connected with first joint and second respectively and connect, have guaranteed that the connecting tube subassembly can link together smoothly with first part and second part to guarantee the normal realization of water dispenser function. In addition, the metal hose body is a universal pipe, has the characteristics of being capable of being bent at any angle and being watertight, and can be connected with the first component and the second component which have different distances, so that the metal hose body has better universality. Such as: to underlying formula water dispenser, the connecting tube subassembly of this application is fit for not the bucket of co-altitude and co-altitude fuselage to establish and is connected, and the commonality is better.
