Abstract
The utility model relates to a vacuum pump head hose tube capable of rebounding, which solves the problem that during the service process of the prior vacuum pump head hose tube, the tube may gradually shrink with the decrease of contents, so as to influence on appearance. The vacuum pump head hose tube comprises a pump head and a tube body, wherein an outer tube is sheathed on the tube body, a buckle is arranged on the outer tube and mates with a clamp on the tube body so as to fix the outer tube and the tube body together, and an air cavity and an air inlet groove communicating the air cavity and the surrounding air are arranged between the outer tube and the inner tube. The vacuum pump head hose tube provided in the utility model ensures the functions of the vacuum pump head hose tube and has esthetic appearance.
Description
Technical field
The utility model relates to a kind of vacuum pump head flexible pipe.
Background technology
Vacuum pump head flexible pipe is made up of pump head and body now, and body can be flat gradually along with the minimizing of content during use, influences outward appearance.
Summary of the invention
The purpose of this utility model is the problems referred to above of existing at existing vacuum pump head flexible pipe, provide a kind of the profile that can guarantee flexible pipe in use can deformation vacuum pump head flexible pipe.
The purpose of this utility model is achieved in that the utility model comprises the vacuum pump head flexible pipe of being made up of pump head and body, outside described body, also be with outer tube, on outer tube, be provided with button bit, thereby match with screens on the body outer tube and body are fixed together, the air inlet duct that is provided with air cavity and air cavity is communicated with ambient atmosphere between outer tube and interior pipe.
Technique effect of the present utility model is: the utility model has increased an outer tube on the basis of existing vacuum pump head flexible pipe, be provided with air cavity between outer tube and the body, and be provided with and make air cavity and the extraneous air inlet duct that communicates, press head and extrude that thereby the air pressure in the air cavity can or not produce deformation by consistent outer tube with ambient pressure behind the content, so not only guaranteed the effect while of vacuum pump head flexible pipe but also reached the effect of appearance looks elegant.
Description of drawings
Fig. 1 is the stereoscopic figure of embodiment.
Fig. 2 is the cutaway view of embodiment.
Fig. 3 is the stereoscopic figure of embodiment middle external tube.
Fig. 4 is the cutaway view of embodiment middle external tube.
Fig. 5 is the cutaway view that embodiment removes other structure behind the outer tube.
The specific embodiment
Present embodiment is the hose construction before the sealing.
Structure shown in Figure 5 is the structure of existing a kind of vacuum pump head flexible pipe before sealing, and it comprises body 1 and pump head, and pump head comprises head 3 and elastic body 4, and its structure is a prior art, does not describe in detail at this.
As shown in Figures 1 to 4, present embodiment is to have increased an outer tube 2 outside the body 1 of vacuum pump head flexible pipe shown in Figure 5, outer tube 2 is enclosed within outside the body 1, head 22 inboards at outer tube are provided with four button bits 21, match with four screens 11 on head 12 outsides of body 1, thereby outer tube 2 and body 1 are fixed together, when in body 1, load onto content and with body 1 and outer tube 2 sealings after, constitute air cavity 5 between the tube wall of outer tube 2 and body 1, and between both heads of outer tube 2 and body 1, be provided with air inlet duct air cavity 5 is communicated with ambient atmosphere.Air cavity 5 is identical with ambient pressure when extruding head 3 uses, outer tube 2 can not produce deformation, has guaranteed the effect that outer tube 2 is attractive in appearance.
Outside the body of the vacuum pump head flexible pipe that has other structure now, set up outer tube, all can realize the utility model.
Claims (1)
1. but resilience vacuum pump head flexible pipe, comprise the vacuum pump head flexible pipe of forming by pump head and body, it is characterized in that: outside described body, also be with outer tube, on outer tube, be provided with button bit, thereby match with screens on the body outer tube and body are fixed together, the air inlet duct that is provided with air cavity and air cavity is communicated with ambient atmosphere between outer tube and interior pipe.
