DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] like Figure 1 As shown, this embodiment discloses a vacuum bottle with adjustable liquid output, including an outer shell 1, an inner bottle 2, a pump body 6, a press cover 3, a limiting ring plate 4, and a bottom cover 5. The inner wall of the outer shell 1 is provided with a stop shoulder 11, the inner bottle 2 is installed in the outer shell 1, the stop shoulder 11 provides a limit for the inner bottle 2, the pump body 6 is fixedly installed at the upper end opening of the inner bottle 2, the pump body 6 is fixedly installed at the bottle mouth of the upper end of the inner bottle 2 through a shoulder sleeve 7, the upper end surface of the large diameter edge of the inner bottle 2 is against the stop shoulder 11 for limit, the upper end of the pump body 6 passes through the stop shoulder 11, the inner bottle 2 includes a piston 21 and an inner cover 22, and the pump body 6 is fixedly installed at the upper end opening of the inner bottle 2. The plug 21 and the inner cover 22 are installed at the lower end opening of the inner bottle 2. The inner cover 22 is located at the outer end of the piston 21. The inner cover 22 includes a pull plate 221. The pull plate 221 is located at the lower end surface of the inner cover 22. The lower end of the pull plate 221 is higher than the lower end of the inner bottle 2. The pull plate 221 is a flat plate extending toward the outer end of the inner bottle 2, which can facilitate pulling the inner bottle 2 outward. The inner cover 22 is provided with a through hole 222. The through hole 222 connects the upper and lower end surfaces of the inner cover 22. The through hole 222 can balance the air pressure above and below the inner cover 22, so that the piston 21 can be normally subjected to atmospheric pressure.
[0026] like Figure 1As shown, the bottom cover 5 is installed at the lower end opening of the outer shell 1, and the bottom cover 5 is connected to the lower end of the outer shell 1 by threads. The inner bottle 2 of this embodiment is a replaceable structure. When the liquid in the inner bottle 2 is used up, the bottom cover 5 is removed, and the pull plate 221 is pulled outward to pull the inner bottle 2 downward for replacement. The bottom cover 5 is against the lower end of the inner bottle 2. There are air gaps between the bottom cover 5 and the outer shell 1 and the inner bottle 2, so that the normal atmospheric pressure is always maintained below the piston 21.
[0027] like Figure 1 , Figure 4 As shown, the limit ring plate 4 is fixedly installed on the inner wall of the outer shell 1, the lower end surface of the limit ring plate 4 is against the upper end surface of the shoulder 11, the limit ring plate 4 is bonded to the inside of the outer shell 1 by glue, the limit ring plate 4 is provided with slots 41 of different depths, the slots 41 are connected to the upper end surface of the limit ring plate 4, the cover 3 is installed on the upper end of the pump body 6, the cover 3 includes a connecting pipe 33, the lower end of the connecting pipe 33 is plugged into the pump body 6, the connecting pipe 33 and the pump body 6 are only provided with detachable limits in the up and down directions, and the connecting pipe 33 and the pump body 6 can rotate relative to each other in the circumferential direction.
[0028] like Figure 1 , Figure 4 As shown, the cover 3 includes an insert plate 31, which is located at the lower end surface of the cover 3, and extends toward the direction of the limiting ring plate 4. The cover 3 can be rotated so that the insert plate 31 can correspond to slots 41 of different depths. When the cover 3 is at the highest position, the lower end of the insert plate 31 is higher than the upper end of the limiting ring plate 4, for example Figure 4 As shown in the figure, the number of slots 41 in this embodiment is six, and the height of the lowest point of each slot 41 is different, so that when the plug plate 31 is inserted into different slots 41, the distance that the cover 3 can be pressed down is different, resulting in different degrees of pressure on the pump body 6 and different amounts of liquid sprayed from the nozzle 34, so that the liquid output of the nozzle 34 can be controlled by rotating the cover 3.
[0029] like Figure 1 , Figure 3 , Figure 4 As shown, more preferably, the slots 41 are evenly distributed in a ring shape, the slots 41 are triangular slots, the lower end of the slots 41 is the smallest end, the shape of the plug plate 31 corresponds to the slot 41, so that when the cover 3 is pressed down, the plug plate 31 is gradually inserted into the slot 41, so that the plug plate 31 can always remain in the corresponding slot 41 without arbitrarily deviating, and the nozzle 34 can accurately correspond to the number mark 13 on the outer surface of the shell 1, and the edges of the upper end opening of the slot 41 are rounded, and the rounded edges serve as a transition. The rounded corners can better guide the plug plate 31 to be inserted into the slot 41.
[0030] like Figure 1 , Figure 2 , Figure 3As shown, the press cover 3 includes a nozzle 34, and the nozzle 34 corresponds to the position of one of the protrusions 32. A quantity mark 13 is provided on the upper end of the outer wall of the shell 1, and the quantity mark 13 corresponds to the position and quantity of the protrusion 32. The press cover 3 is rotated and then the nozzle 34 rotates to correspond to the quantity mark 13. The quantity mark 13 on the outer wall of the shell 1 can play a marking role when the press cover 3 is rotated. The corresponding quantity mark 13 corresponds to the amount of liquid discharged when the press cover 3 is pressed once. The user can rotate the press cover 3 so that the nozzle 34 roughly corresponds to the quantity mark 13. When the press cover 3 is pressed, the nozzle 34 accurately corresponds to the quantity mark 13 due to the cooperation between the plug plate 31 and the slot 41.
[0031] like Figure 2 , Figure 3 , Figure 4 As shown, a gap is provided between the inner wall of the shell 1 and the outer wall of the press cover 3, the inner wall of the shell 1 is provided with a limiting convex strip 12, the limiting convex strips 12 are evenly distributed in a ring shape, the outer wall of the press cover 3 is provided with a convex block 32, the convex blocks 32 are evenly distributed in a ring shape, each convex block 32 is located between two adjacent limiting convex strips 12, each limiting convex strip 12 is correspondingly located in the middle position of two slots 41, the limiting convex strip 12 is located above the limiting ring plate 4, the space between two adjacent limiting convex strips 12 corresponds to the position of the slot 41 of the lower limiting ring plate 4, when the press cover 3 is rotated, the convex block 32 presses against the limiting convex strip 12 to elastically deform the side wall of the press cover 3, so that the convex block 32 can pass over the limiting convex strip 12, when the nozzle 34 corresponds to different quantity markings 13, the convex block 32 can be located between the corresponding two adjacent limiting convex strips 12, and the two limiting convex strips 12 limit the convex block 32 to prevent the press cover 3 from rotating too much.
[0032] More preferably, the button cover 3 can be rotated so that the limiting ridge 12 and the protrusion 32 can abut against each other. The edges where the limiting ridge 12 and the protrusion 32 abut against each other are arc-shaped. The arc-shaped contact surface can just force the protrusion 32 to pass over the limiting ridge 12, so that the user can have a better hand feeling when rotating the button cover 3.
[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
