Abstract

The utility model relates to a single-spring vacuum imbibition bottle, which comprises a press head, a limit seat, a spring, a piston, a body, a sliding plug and a bottle body; the liquid-discharging valve is characterized in that the outer edge of a body with a liquid inlet hole in the middle is connected with a bottle opening of a bottle body in a sealing mode, a pressing block for pressing a lower sealing pad is arranged on the periphery of the liquid inlet hole, the lower sealing pad extends towards the liquid inlet hole to cover the liquid inlet hole, so that the lower sealing pad and the liquid inlet hole become a one-way valve which can only be opened upwards, an inner pipe extends upwards from the peripheries of the liquid inlet hole and the pressing block, a piston is placed in the inner pipe, a liquid outlet hole which is covered with an upper sealing pad is formed in the middle of the piston, a connecting pipe sleeve extends upwards from the periphery of the liquid outlet hole to connect a middle pipe of a limiting seat, the lower end of the middle pipe presses the upper sealing pad to enable the upper sealing pad and the liquid outlet.

Description

Single spring Vacuum imbibition bottle

Technical field:

The utility model relates to a kind of container, particularly a kind of single spring Vacuum imbibition bottle.

Technical background:

The packing container of existing liquid daily-use chemical industry such as shampoo, shower cream etc. mostly is to establish the piston pump of a band suction pipe at an upper portion thereof and stretch in the container suction pipe with the liquid sucking-off in the container, the inside of this packing container must be communicated with the pressure inside and outside the equalizing reservoir with the atmosphere in the external world, otherwise can be because of the inwardly shrinkage distortion of in-to-in negative pressure with regard to can not inhaling liquid or container; Its shortcoming is to cause the interior volatilization as materials such as spices of container easily, has influenced the result of use of product.

Summary of the invention:

Technical matters, the purpose of this utility model just provides a kind of vacuum self-priming lotion pump without suction pipe, it solved exist in the existing daily-use chemical industry container because of internal tank must communicate with atmosphere cause material in the container volatile, influenced the problem of the result of use of material in the bottle.

Technical scheme:

The purpose of this utility model is achieved in that a kind of single spring Vacuum imbibition bottle, comprises that head, limit base, spring, piston, body, sliding plug and bottom have the straight simple shape bottle of breather hole; It is characterized in that the middle part has the body outer rim of inlet opening and the bottleneck of bottle is tightly connected, the inlet opening periphery is provided with the briquetting of pushing down down packing, following packing covers inlet opening to the inlet opening extension and makes down packing and inlet opening become the check valve that can only upwards open, inlet opening and briquetting periphery protrude upward interior pipe, place the piston that external diameter and this internal diameter of tube body match in the interior pipe, the piston middle part has the fluid hole that is stamped packing on it, the fluid hole periphery protrudes upward the middle pipe that the connection pipe cover is caught limit base, packing is pushed down in middle pipe lower end makes packing and fluid hole become the check valve that can only upwards open, the middle pipe of limit base and the liquid outlet channel of head join, and are provided with inhibiting device between limit base and body.

Described single spring Vacuum imbibition bottle is characterized in that described inhibiting device is to be provided with the outer tube coaxial with interior pipe on body, and outer tube top is provided with the annular stop muscle, and the limit base outer periphery has limit dais.

Beneficial effect, owing to adopted technical scheme described in the utility model, when the head of pushing single spring Vacuum imbibition bottle repeatedly makes bottle interior liquid discharge by the head outlet, owing to produce negative pressure in the bottle, so the sliding plug that will be positioned at bottle is simultaneously inhaled and is made sliding plug upward movement till bottle liquid is sucked to bottle, bottle inside that is to say that single spring Vacuum imbibition bottle described in the utility model is effective volume reaches equilibrium air pressure in the decreased locomotion bottle with piston effect, so need not communicate with the external world; Thereby avoided a bottle interior material to evaporate in the atmosphere, guaranteed that the result of use of the interior material of bottle also can prolong the effective life of bottle interior material.

Description of drawings:

Accompanying drawing is the cut-away view of an embodiment of single spring Vacuum imbibition bottle described in the utility model.

Drawing explanation: 1-cover of dust, 2-head, 3-leakproof plug, 4-limit base, the 41-pressure head, the 42-limit dais is managed among the 43-, the 5-spring, the 6-piston, 61-fluid hole, 62-connection pipe, 7-body, the 71-suction chamber, 72-inlet opening, pipe in the 73-outer tube, 74-, the spacing muscle of 75-, the last packing of 81-, packing under the 82-, 9-briquetting, the 10-bottle, 101-breather hole, the sliding plug of 11-.

The specific embodiment:

As seen from the figure, described single spring Vacuum imbibition bottle comprises that head 2, limit base 4, spring 5, piston 6, body 7, sliding plug 11 and bottom have the straight-tube shape bottle 10 of breather hole 101; Having body 7 outer rims of inlet opening 72 and the bottleneck of bottle 10 is tightly connected, inlet opening 72 peripheries are provided with the briquetting 9 of pushing down down packing 82, following packing 82 covers inlet opening 72 to inlet opening 72 extensions, pipe 74 in body 7 is provided with, place pistons 6 in the interior pipe 74, piston 6 middle parts have the fluid hole 61 that is stamped packing 81 on it, fluid hole 61 peripheries protrude upward the middle pipe 43 that connection pipe 62 covers are caught limit base 4, the pressure head 41 of middle pipe 43 lower ends is pushed down packing 81 makes packing 81 and fluid hole 61 become the check valve that can only upwards open, the middle pipe 43 of limit base 4 joins with the liquid outlet channel of head 2, body 7 is provided with the outer tube 73 coaxial with interior pipe 74, outer tube 73 tops are provided with annular stop muscle 75, and limit base 4 outer periphery have limit dais 42; 7 of limit base 4 and bodies are equipped with spring 5; The effect of leakproof plug 3 is to be used at ordinary times that outlet with head 2 clogs in order to avoid bottle when being inverted, and liquid flows out in the bottle; The effect of cover of dust 1 is to be used for preventing airborne dust pollution head obsolete the time.

Principle of work: press head 2, following packing 82 is closed inlet 72, and pressure strengthen in the suction chamber 71, will go up upwards top and open liquid outlet 61 of packing 81, and the liquid in the suction chamber 71 sprays from spout through the liquid outlet channel that the middle pipe 43 of limit base enters head 2; After unclamping hand, head 2 is upward movement under the effect of spring 5, last packing 81 is closed liquid outlet 61, thereby will descend packing 82 upwards to inhale to make the interior pressure of bottle interior pressure and suction chamber 71 the same because of producing negative pressure in the suction chamber 71, sliding plug 11 top and bottom produce pressure reduction and are upwards pushed away by bar pressure, and liquid is sent in the suction chamber 71.
