Specifically, the surface of carrier liquid case 2 is equipped with the feed liquor chamber, the internal connection in feed liquor chamber has feed liquor stopper 23, platen 21's initial position is located honeycomb duct 3's top below, platen 21 and carrier liquid case 2's inner wall looks adaptation for platen 21 is when the upward movement, and the washing liquid that the surface bore can get into honeycomb duct 3's inside, and when platen 21 resets downwards, the washing liquid is synchronous downwards to the inside outflow that can not appear the washing liquid along honeycomb duct 3 always, has guaranteed the normal use of whole device.

Considering that the pressing plate 13 may deviate when the pressing plate 13 leaves the box body 1 when moving vertically, the surface of the pressing plate 13 is provided with a plurality of sliding cavities 132, the sliding arms 12 are provided in a plurality of numbers, the sliding arms 12 penetrate through the inside of the sliding cavities 132, the sliding cavities 132 and the sliding arms 12 are in sliding connection, when the pressing plate 13 is driven upwards or downwards through the screw rods 14, the pressing plate 13 is in vertical transmission under the sliding limit of the sliding arms 12 and the sliding cavities 132, and when the pressing plate 13 leaves the inside of the box body 1, the pressing plate 13 still is in vertical transmission and cannot rotate synchronously along with the screw rod nuts 131.

Considering that the whole equipment is large in volume when carried outside, the surface of the catheter 16 is provided with the connecting plate 161, one side of the connecting plate 161 is provided with the shaft rod 162, the shaft rod 162 is hinged and fixed with the liquid carrying tank 2, and the connecting plate 161 is used for adjusting the position of the catheter 16.

Considering that when the liquid guide tube 16 and the atomizing spray head are damaged, the maintenance cost is overlarge due to the fact that the liquid guide tube 16 cannot be conveniently replaced, the liquid guide tube 16 is made of two sections, an inner tube 163 is installed at one end of one liquid guide tube 16, the inner tube 163 is in threaded connection with the other liquid guide tube 16, the liquid guide tube 16 is made of rubber materials, has certain flexibility and is beneficial to bending, the atomizing spray head is made of precise metal support, when the liquid guide tube 16 and the atomizing spray head are damaged due to accidental collision, one end connected with the atomizing spray head can be screwed out through the liquid guide tube 16, the atomizing spray head and the liquid guide tube 16 can be replaced, and later-period use and maintenance costs are saved; wherein, when powdered medicament and liquid mixed use are placed in box 1, lead to catheter 16 to be blockked up, equally can twist out one end of catheter 16, the whole length of catheter 16 reduces, does benefit to and carries out convenient clearance to catheter 16 that blocks up.

Considering that it is not convenient enough in the box 1 when initially putting into the liquid medicine, breach 17 has been seted up at the side top of box 1, breach 17 is used for putting into the medicament, the edge of breach 17 articulates there is baffle 18, baffle 18 is used for the sealed to breach 17, wherein, baffle 18's surface is equipped with the arch, the arch can block completely in the inboard of breach 17, make cooperation between breach 17 and the baffle 18, after throwing into the medicament along breach 17, baffle 18 card goes into breach 17, avoid breach 17 to expose to fall into the inside influence of dust to box 1 and use.

Considering 133 slides at the inside wall of box 1, laminating not sealed enough with lumen 31 and appearing the gap, lead to in the liquid medicine gets into honeycomb duct 3, cavity 19 has been seted up on the surface of box 1, cavity 19 is located lumen 31, dog 133 is located the inside slip of cavity 19, has changed the connected mode among the above-mentioned, through the laminating of cavity 19 and dog 133 being connected, make cavity 19 can block sealed lumen 31 completely, appear the gap when avoiding blockking lumen 31 and lead to inside liquid to flow out along lumen 31.

Example 2

Considering that the mask 164 is exposed directly to the outside when not in use, and the dust in the air adheres to the surface, which affects the subsequent use, this embodiment makes the following improvements on the basis of embodiment 1, as shown in fig. 9 and 10:

the side face of the face mask 164 is provided with a shielding cover 4, the surface of the shielding cover 4 is symmetrically provided with connecting blocks 41, the connecting blocks 41 are hinged with the face mask 164, the inner diameter of the shielding cover 4 is larger than that of the face mask 164, the shielding cover 4 is used for sealing the face mask 164, and after the face mask 164 is used, the shielding cover 4 can be turned over along the hinged part, so that the shielding cover 4 is positioned on the side of the face mask 164, and the opening side of the face mask 164 is prevented from being exposed outside and polluted by dust in the air; meanwhile, when other foreign matters are attached to the surface of the face shield 164 in the using process, the face shield 4 can be synchronously sealed with the face shield 164 when the box body 1, the liquid guide tube 16 and the atomizing nozzle are cleaned, so that the cleaning liquid can contact the surfaces of the face shield 164 and the face shield 4 through the atomizing nozzle, and particles of the cleaning liquid are in reverse motion due to collision after contact, so that the cleaning liquid is splashed on the surfaces of the face shield 164 and the face shield 4 to wash away the foreign matters attached to the face shield 164.

When considering that personnel wear face guard 164, the shield 4 is unfavorable for folding the storage, and arc chamber 42 has been seted up on the surface of shield 4, and arc chamber 42 can be with catheter 16 adaptation connection, and when shield 4 need not to use, can turn over shield 4 along connecting block 41 book for arc chamber 42 is along catheter 16's surface joint, and shield 4 can the side direction card on catheter 16's surface this moment, and when personnel worn face guard 164, do not receive the influence.

Considering that the arc cavity 42 is opened to cause the shielding cover 4 to be in an exposed state when the shielding cover 4 closes the face mask 164, or to cause dust to enter, the bottom of the arc cavity 42 is opened with a cavity, a sliding block 43 is arranged inside the cavity, the sliding block 43 is matched with the arc cavity 42 in size, a spring 44 is installed at the end of the sliding block 43, the spring 44 is located in the cavity, due to the opening of the arc cavity 42, the surface side of the shielding cover 4 is in an exposed state, when the shielding cover 4 leaves the catheter 16 and is in a closed face mask 164, the sliding block 43 in the cavity is extended outwards under the elastic force of the spring 44, so that the sliding block 43 is attached to and slides on the arc cavity 42 to be sealed, and when the shielding cover 4 is turned over to one side, the sliding block 43 is contacted with the catheter 16 and is extruded and retracted to the inner side of the cavity, thereby ensuring that the shielding cover 4 can be in a closed state when the face mask 164 is sealed, dust cannot enter, and when the person wears the mask 164, the shielding cover 4 can be connected with the catheter 16 after being retracted without being folded, and the person does not wear the mask 164.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
