Abstract
A water injection deflation device installed on an electric hot water bag belongs to the technical field of appliance safety. The device consists of a hole body which is arranged on the electric hot water bag in a heat seal way, a bottom cover which is connected with the lower end of the hole body by screw thread, a sealing rod with one offsetting spring which is arranged in the hole body with one end passing through the hole body to stretch out of the electric hot water bag and the other end passing through the bottom cover to stretch out of the bottom cover, a sealing rubber ring which is arranged on the sealing rod for sealing the channel between the outside stretching end of the sealing rod and the hole of the hole body and a water inlet air-bleed hole which is arranged on the wall of the hole body. The sealing rod is pressed down, and then water can enter the hole body and flow into the bag through the water inlet air-bleed hole on the wall of the hole body. During the deflation, the sealing rod is pressed down, and the residual air in the bag can also be discharged out of the water inlet air-bleed hole. The water injection deflation device has the advantages of simple structure, convenient use, safety and reliability.
Description
Affiliated technical field
The utility model relates to the water filling means of deflation that is installed on the electric hot-water bag.Belong to household electrical appliances safe practice field.
Background technology
The water filling means of deflation that is provided with on the electric hot-water bag is all very simple at present, generally all is that a hole is set, and with the stopple sealing, water filling and venting all will be pulled up stopple, and be very inconvenient.The general user can not exit, and the time has been grown, and residual gas is too much in the bag, can be excessive during heating because of pressure, cause electric hot-water bag blast or explosion, and lead to a disaster, even hurt sb.'s feelings.
Summary of the invention
The purpose of this utility model is to overcome the inconvenience that the water filling venting must be opened stopple, for electric hot-water bag provides a kind of water filling means of deflation.
This water filling means of deflation by the hole body of heat seal on electric hot-water bag, be threaded in body lower end, hole bottom, be located in the body of hole and an end passes that the hole body is stretched outside electric hot-water bag, the other end passes bottom and stretches the seal bar that has a back-moving spring outside bottom, is arranged on the O-ring seal of the passage between the hole of shutoff seal bar overhanging end on the seal bar and hole body and the water inlet air vent that is arranged on the body wall of hole is constituted.The water filling venting time only need be depressed seal bar, makes O-ring seal leave the hole body, has promptly removed the stifled close of passage between the hole of seal bar overhanging end and hole body, and water can enter into the inflow of the water inlet air vent on via hole body wall bag again of hole body by this passage.During venting, depress seal bar, it is to avoid false touch to stretch seal bar outside electric hot-water bag to cause and leak that residual gas in the bag also can be emitted bag outer from this air vent of intaking, cause and leak for avoiding false touch to stretch seal bar outside electric hot-water bag, can be at recess of top design of hole body, set a port lid in recess, the external part of seal bar is stretched in this port lid.
Major advantage of the present utility model is simple in structure, and water filling and venting all only need be depressed and be passed the seal bar that the hole body stretches outside electric hot-water bag and get final product.Easy to use, safe and reliable.
Description of drawings
Diagram is a structural representation of the present utility model
The specific embodiment
Referring to diagram, this water filling means of deflation by the hole body 1 of heat seal on electric hot-water bag 7, be threaded in body lower end, hole bottom 5, be located in the hole body 1 and an end passes that hole body 1 is stretched outside electric hot-water bag, the other end passes bottom 5 and stretches the seal bar that has a back-moving spring 32 outside bottom, is arranged on the O-ring seal 4 of the passage 8 between the hole of shutoff seal bar overhanging end on the seal bar 2 and hole body and the water inlet air vent 9 that is arranged on hole body 1 wall is constituted.For avoiding false touch to stretch seal bar 2 outside electric hot-water bag, be provided with a recess 10 at the top of hole body, in recess 10, set a port lid 6, the external part of seal bar 2 is hidden in this port lid leaks to avoid false touch to cause.When depressing seal bar 2, O-ring seal 4 moves down along with seal bar 2 and leaves hole body 1, promptly removed the shutoff of the passage 8 between the hole of seal bar overhanging end and hole body, water can by this passage advance the people in the body of hole again the water inlet air vent 9 on via hole body wall flow in the bag.Discharge seal bar 2, reset, drive that O-ring seal 4 resets and passage 8 shutoff at the effect lower seal bar 2 of back-moving spring 3.During venting, depress seal bar, the residual gas in the bag can be emitted outside the bag through passage 8 from water inlet air vent 9.
Claims (2)
1, water filling means of deflation, it is characterized in that described water filling means of deflation by the hole body of heat seal on electric hot-water bag, be threaded in body lower end, hole bottom, be located in the body of hole and an end passes that the hole body is stretched outside electric hot-water bag, the other end passes bottom and stretches the seal bar that has a back-moving spring outside bottom, is arranged on the O-ring seal of the passage between the hole of shutoff seal bar overhanging end on the seal bar and hole body and the water inlet air vent that is arranged on the body wall of hole is constituted.
