The liquid applying mechanism is used for applying liquid to the sealed container 1; a spray nozzle 4 (i.e. an atomization nozzle) which is intermittently communicated with the sealed container 1 by a medicine conveying pipe 3 is arranged in the shell 2, and the liquid applying mechanism applies pressure to the sealed container 1, so that the fluid in the sealed container 1 is pressed into the spray nozzle 4 through the medicine conveying pipe 3 to finish the liquid applying action; preferably, the spray nozzle 4 is located at the top of the housing 2, and can spray the vapor upward, and the spray nozzle 4 can be mounted on the side wall of the housing 2 to spray the medicine forward, or at other suitable positions.
The liquid applying mechanism comprises an air bag 9, an air inlet pipe 37, a medicine conveying pipe 3 and an air feeding pipe 10. The air bag 9 is used for supplying air to the sealed container 1, and after the air bag 9 is pressed, the air in the air bag 9 is pressed into the sealed container 1.
The air inlet pipe 37 is arranged on the air bag 9, the other end of the air inlet pipe 37 extends into the sealed container 1, the length of the air inlet pipe 37 extending into the sealed container 1 is short, about 0.5-2mm, and the air inlet pipe 37 is only required to be communicated with the sealed container 1, and the end part of the air inlet pipe 37 in the sealed container 1 is in an outward expansion cone shape, so that the air inlet pipe is limited and fixed.
One end of the medicine delivery tube 3 is inserted into the bottom of the sealed container 1, and the other end extends out of the sealed container 1, and then penetrates out of the shell body of the shell 2 to be connected with the spray nozzle 4.
The air supply pipe 10 is used for supplying air to the air bag 9, so that air is pumped from the atmosphere when the compressed air bag 9 is restored, and negative pressure in the sealed container 1 caused by pumping air from the sealed container 1 is avoided, and fluid is prevented from being pumped into the air bag 9. The air supply pipe 10 is connected with the air inlet pipe 37 and the air bag 9 through the three-way joint 36, and the other end of the air supply pipe 10 penetrates through the shell 2 and then is communicated with the atmosphere.

The valve plate 7 slides between the first auxiliary locking piece 33 and the second auxiliary locking piece 34, alternately clamps the drug delivery tube 3 in cooperation with the first auxiliary locking piece 33 and clamps the air delivery tube 10 in cooperation with the second auxiliary locking piece 34, so that corresponding hoses can be reliably clamped and deformed. Specifically, a forwardly extending lug 44 is provided at the left end of the valve plate, and the lug 44 is engageable with the second auxiliary lock block 34 to clamp the air tube 10.
Examples
The embodiment adds an actuating component which is convenient for hand-held operation on the basis of the embodiment 1, the air bag 9 can be easily extruded by the actuating component to press air into the sealed container 1, and meanwhile, the actuating component also rotates the swinging rod 5 to enable the valve plate 7 to move between the applying position 11 and the cutting-off position 12, and the actions can be easily and synchronously completed by only one hand action.
The specific scheme of the embodiment is as follows:
referring to fig. 1, 4 and 7, the liquid applying mechanism further includes an actuating assembly, the actuating assembly includes a rotating shaft 13 mounted on a side wall of the housing 2, and the rotating shaft 13 is fixedly mounted or connected with a first connecting rod 14 and a second connecting rod 15 to form an included angle, where the included angle may be an acute angle, an obtuse angle or a flat angle, and preferably, the first connecting rod 14 and the second connecting rod 15 are distributed on left and right sides of the rotating shaft 13.
The actuating assembly further comprises a crank arm handle 16 which approximates an L shape, referring to FIG. 5, the two arms of the crank arm handle 16 are a wrench arm 18 and a transmission arm 19 respectively, the wrench arm 18 and the transmission arm 19 intersect at a bending portion 17 of the crank arm handle, and the wrench arm 18 is preferably longer than the transmission arm 19, so that the use is more labor-saving. The bending part 17 of the crank arm handle is hinged on the shell 2, and the wrench arm 18 of the crank arm handle protrudes outwards from the shell 2, so that the wrench arm 18 can be conveniently pressed by hands. The transmission arm 19 of the crank handle is hinged to the end of the first link 14 remote from the rotation shaft 13.
Referring to fig. 1 and 4, a second link 15 is hinged with a second push rod 20 at the end far from the rotating shaft 13, the end is provided with a waist-shaped hole 29, and the second push rod 20 is hinged in the waist-shaped hole 29; when the ejector rod 20 rises, the air bag 9 is extruded, and when the spanner arm 18 is forced to rotate forwards, the transmission arm 19 drives the first connecting rod 14 to rotate in the same direction, the first connecting rod 14 drives the rotating shaft 13 to rotate synchronously, and the rotating shaft 13 drives the second connecting rod 15 to rotate in the same direction, so that the second connecting rod 15 jacks up the ejector rod 20 upwards.
The top of ejector rod 20 is fixed and installs layer board 40, and layer board 40 top is fixed with the central silica gel pad 41 that is the arc indent, also is fixed with the silica gel pad 41 of similar structure on the roof of shell 2, and the top and the bottom of gasbag 9 are fixed in respectively on two silica gel pads 41 in the bonding. The bottom of the air bag 9 is pressed into the sealed container 1 by the air in the air bag 9 after being extruded by the ejector rod 20, when the ejector rod 20 is reset downwards, the bottom of the air bag 9 descends along with the silica gel pad 41 and the ejector rod 20, and the top of the air bag 9 is fixed on the top wall of the shell 2, so that the shape of the air bag 9 can be quickly restored after the air bag 9 is stretched downwards by the ejector rod 20.
The traction rope 6 is tensioned in a bending shape, the vertical part 25 of the traction rope is connected with the swing rod 5, and the transverse part 26 of the traction rope is connected with the valve plate 7; the left vertex angle of the supporting platform 43 is provided with an inclined wheel seat 27, the inclined wheel seat 27 is provided with a follower wheel 28, and the bending part of the traction rope is tensioned on the follower wheel 28.
The swing rod 5 is hinged on the shell 2 near the rotating shaft 13, and the right end of the swing rod 5 is upwards arranged by being pulled by the elastic body I8 and the traction rope 6 in a normal state. Referring to fig. 1, 2 and 4, a cam 21 is fixedly mounted or keyed on the rotating shaft 13, and when the cam 21 rotates along with the rotating shaft 13, one end of the swing rod 5, which is far away from the traction rope, is jacked up, namely, the left end of the swing rod 5 in the drawing, so that the swing rod 5 pulls the traction rope downwards, and the valve plate 7 is moved.
Since the liquid applying position 11 and the cutting position 12 are basically fixed, the valve plate 7 cannot move further after moving to the set position, and the rotating shaft 13 may still rotate further, so that the valve plate 7 moves beyond the position, and therefore the moving stroke of the valve plate 7 is limited by the following structure: the cam 21 is a concentric reducing wheel, namely, the cam 21 comprises a large-diameter rim 22 and a small-diameter rim 23 which are concentric with the rotating shaft, the radius of the large-diameter rim 22 is larger than that of the small-diameter rim 23, and the joint of the large-diameter rim 22 and the small-diameter rim 23 is smoothly transited by a slope. In the initial state, the small diameter rim 23 of the cam 21 approaches the swing link 5, and does not exert a thrust force sufficient to rotate the swing link 5.
