Specific embodiment
In order to keep technical purpose of the invention, technical scheme and beneficial effects clearer, with reference to the accompanying drawing and specifically
Embodiment is further illustrated technical solution of the present invention.
The embodiment one of humidifier: as shown in Fig. 2, humidifier includes water flowing out structure；Water flowing out structure include pressure piping 2,
Spray head 1, the valve being arranged between pressure piping 2 and spray head 1 connect class device 3 and spray head prevents that wounded device, spray head prevent wounded dress
The shell including closed ABS plastic material is set, shell is made of two up big and down small tapered parts, and taper is arrived from above
Under be sequentially increased.
The top of shell is equipped with the conduit entrance 7 for avoiding pressure piping 2, and the bottom of shell is equipped with for shell to be discharged
Four drainage holes 8 of internal water accumulation, drainage hole 8 are equipped with the threaded hole of supply and discharge water pipe connection.Side wall of outer shell is equipped with to be connected for spray head 1
Connector sleeve 6, the inner port of connector sleeve 6 enters for spray head 1, external port is sprayed for spray head 1.It is also set at the external port of connector sleeve 6
There is the turn edge for carrying out block to spray head.In order to adapt to different environment, shell is also possible to other materials, such as stainless
Steel material.
Shell includes first shell 4 and the second shell being detachably connected with first shell 45.First shell 4 and second shell
Connection respectively corresponds the shell company for being equipped with and screwing in for screw 10 there are three screw 10 between body 5 in first shell 4, second shell 5
Hole 9 is connect, the leather plug 11 for blocking shell connecting hole 9 is equipped in shell connecting hole 9.In other embodiments, it can also be equipped with
The discharge outlet of other quantity, such as total discharge outlet quantity are six；It may be arranged as the shell of other quantity, adjacent housings can
Releasably connect.
Spray head of the present invention prevent wounded device in humidification, spray head part of the shell seal in addition to spray head spout, and
And shell by taper increase from top to bottom difference it is tapered form, spinning chip is only attached to outer casing top surface, and humidifying effect is significant,
It effectively prevent at spray head dripping because adhering to spinning chip, and shell side is flat and smooth, cleaning difficulty is small, cleaning frequency
It is low.
In addition, the spout of spray head and the distance between the external port of connector sleeve are according to the injection taper of the spray head of actual use
It determines, the taper that the edge of guarantee spout central and connector sleeve external port is formed by tapered space is not more than the spray cone of spout
Degree avoids connector sleeve that water mist is stopped to spray.It is equipped with the turn edge for carrying out block to spray head at the external port of connector sleeve, is pacifying
During casing, nozzle position is limited.
In addition, shell uses ABS plastic material, tough and tensile matter is hard, heat-and corrosion-resistant, low manufacture cost；Shell is led to by shell
It is detachably connected to cross connection structure, cleaning easy to disassemble；Connection structure is using the shell connecting hole and screw opened up on shell
Combination, structure is simple, low manufacture cost, stable connection；It is additionally provided with the leather plug for blocking shell connecting hole on shell, seals
Property is good, is not easy to accumulate spinning chip, and prevent screw from getting rusty.
The embodiment two of humidifier: as shown in figure 3, with embodiment one the difference is that, shell in connector sleeve 6 with
On part is up-small and down-big dome-type, in connector sleeve part below is cylindrical type, setting is there are two spiral shell on the shell
Silk 10 and the threaded hole connected equipped with a discharge outlet 8, discharge outlet 8 equipped with supply and discharge water pipe in outer casing bottom.The embodiment
Structure significantly extends the accumulation period that spray head prevents spinning chip on wounded device, shell cleaning frequency reduce, but at spray head according to
Old to drip because accumulating spinning chip, humidifying effect is poor.
The embodiment three of humidifier: as shown in figure 4, with embodiment two the difference is that, shell in connector sleeve 6 with
On part be up big and down small circular platform type, in connector sleeve part below be up big and down small dome-type.With embodiment two
It compares, spinning chip is greatly decreased in the attachment phenomenon of curved surfaces, is difficult to accumulate spinning chip at spray head.Spinning chip is outside
The attachment phenomenon in shell-side face is greatly decreased, and is difficult to accumulate spinning chip at spray head.But the slope variation of shell side is relatively slow, is spinning
Knit flyings attachment it is serious when, it is spraying to may interfere with spray head.
The example IV of humidifier: shell is also possible to other shapes, for example, the cross section of shell can be rectangle, packet
Two shells that symmetry axis extends along rectangle diagonal are included, two housings, which are equipped with, is used for connection structure interconnected, or
Person's shell can be up-small and down-big/up big and down small triangular pyramid type.
The embodiment five of humidifier: according to the difference of spray head quantity, the connector sleeve of other quantity, example can also be correspondingly provided with
As there are four spray heads, shell inside to be correspondingly provided with four connector sleeves for spray head connection for connection on pressure piping.
The embodiment six of humidifier: it can also be fixedly connected, such as connected by other connection structures between adjacent housings
Structure is buckle structure.
Spray head prevents the embodiment of wounded device: spray head prevents any embodiment of the humidifier of wounded device and aforementioned present invention
In spray head prevent that wounded apparatus structure is identical, therefore be not repeated to illustrate.
Technical solution of the present invention that the above embodiments are only illustrative and not limiting, what any couple of present invention carried out, which be equal, replaces
The modification or part replacement for changing and not departing from spirit and scope of the invention, should all cover the model in the claims in the present invention protection
Within enclosing.
