Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is used only for explaining The utility model is not used to limit the utility model.

As shown in Figs 1-4, a kind of ultrapure water machine water outlet fills head, including shell, sealing ring 12, filter layer 14, filter 16, Transparent protective cover 5 and elastic washer 13；The shell includes first shell 1 and second shell 3；The first shell 1 includes two A outer diameter section, the outer diameter of middle and upper part are greater than the outer diameter of lower part, and two sections are respectively provided with external screw thread, among the second shell 3 With door 2, gas vent 7 is arranged circumferentially on the door；The grai twisted 23 of evagination is set on the door side wall；Wherein it is vented Hole is 2 circles；Internal screw thread, the external screw thread and second shell 3 that the first shell 1 passes through lower part are set at the top of the second shell 3 The female thread at top is threadedly coupled at dismountable；It is holding area between the external screw thread and door 2 on 1 top of first shell 8, sterilizing layer is set on the holding area 8；Sterilizing layer is the antiseptic gauze stratum reticulare being pasted on holding area；It is set on the sterilizing layer Plastic grid is set, grid can increase abrasive feel, take convenient for hand.Stepped hole, the stepped hole packet are set in the second shell 3 Three different diameter circular channels are included, are first passage 21, second channel 10 and third channel 11 respectively from top to bottom；It is described Filter layer 14 is arranged in first passage, and the sealing ring setting is at 14 top of filter layer and is located in first passage, the bullet Property washer 13 be located at the bottom of filter layer 14, elastic washer uses common disinfection silica gel pad, 10 bottom surface of second channel Dashpot 22 is set；The filter 16 is fixed on by connecting rod 15 in 11 inner wall middle position of third channel；The third Vias inner walls bottom has a leakproof cavity 18；Specifically, there is a conical inboard wall 17, the third in third channel 11 The internal diameter at 11 top of channel is gradually increased from top to bottom, and the internal diameter at top is less than the internal diameter of second channel 10, the conical inboard wall 17 bottom has an annular groove 20, the smooth formation leakproof cavity of base contact surface of the annular groove 20 and conical inboard wall 17 18.The 3 outer wall spaced set air discharge duct 6 of second shell, the depth of the air discharge duct gradually becomes shallower as from the bottom up；Described Two shells, 3 bottom has the spray head 4 of an elliposoidal, and transparent protective cover 5 is arranged on the spray head；The transparent protective cover 5 with There is the tread plate 52 of vertical arrangement, the tread plate 52 has elasticity on the inner wall of spray head contact.

Filter layer 14 above-mentioned is activated carbon filter layer, is made of wood materials, filter effect is strong.

It include end aperture in spray head 4 above-mentioned, the internal diameter of the end aperture is less than the internal diameter at 17 top of conical inboard wall.

Venthole 53, a diameter of 1~3mm are set on transparent protective cover 5 above-mentioned.

Filter 16 above-mentioned is activated carbon fibre screen cloth, 5~6mm of mesh.

The filter layer 14 being arranged in first passage can play the function of disinfection and sterilization, increase water outlet and fill the self-cleaning of head Property, since stepped hole being arranged in second shell 2, they are sequentially reduced from top to bottom, and pressurization can be formed to water flow so that can To accelerate the conveying of water outlet；Sealing ring 3 between first shell 1 and second shell 2 can prevent water flow connecing from them It is omitted between contacting surface；Simultaneously when using container bottle (such as kettle, water bottle lamp, bent neck cup) water receiving, second shell is allowed Spray head is inserted into vessel port, since air discharge duct is arranged in second shell outer wall, is not needed this when by adjusting ultrapure water machine Itself reduces the flow velocity of draining, can be realized in container bottle and is vented on one side, water-saving on one side, meanwhile, the door of design can be with It is excessive that realization avoids spray head from protruding into vessel port, plays the role of barrier effect, the gas vent on door can also play exhaust.When It closes after conveying water, remaining water can fall along inner wall in shell, enter second shell along the inner wall of first shell, From first passage in second shell, dashpot on the first pass can play a small amount of remaining flowing water of receiving, avoid water It flows through and flows down more, while the residual water droplet of a part, third channel is entered by second channel, last third channel is along taper Inner wall is fallen in a ring groove, and annular groove can play barrier effect to remaining water droplet, water droplet can be stopped from end aperture in this way From falling.The transparent protective cover designed on spray head can play the role of isolation.
