Abstract
The utility model provides an electromagnetic valve for electronic blood-pressure meter and comprises a seal pad for air tap, an armature, a coil and an air tap. The armature is arranged in the coil, the front end of the armature is provided with a groove, one end of the seal pad for air tap is arranged in the groove, the other end of the pad is connected with the air tap through a spring, the seal pad for air tap comprises a base in the groove and a protruding staging seal head, and the diameter of the seal head is less than the diameter of the base while being more than that of the air tap; the electromagnetic valve for electronic blood-pressure meter of the utility model adopts staging-shaped seal pad for air tap with good manufacturability and reliable sealing and then improves the reliability and stability of the whole product quality.
Description
Technical field
This utility model relates to a kind of electromagnetic valve, particularly relates to a kind of electric sphygmomanometer electromagnetic valve.
Background technology
At present, electric sphygmomanometer is a kind of medical health care products commonly used, is applied in the daily life more and more widely.The import and export of the air bag of electric sphygmomanometer need be controlled the inflation and the venting of air bag with electromagnetic valve.As shown in Figure 1, existing electromagnetic valve, the sealing gasket at its valve place is a slab construction, this structure is unfavorable for valve is sealed, leak gas easily during therefore actual the use, particularly gas leak phenomenon is particularly evident when low-voltage, more seriously has influence on the accuracy of blood pressure measurement, and product quality can not guarantee.
The utility model content
For remedying above-mentioned defective, the purpose of this utility model provides the electric sphygmomanometer electromagnetic valve that a kind of performance is reliable more, be difficult for gas leakage.
A kind of electric sphygmomanometer electromagnetic valve, comprise valve sealing gasket, armature, coil and valve, armature places coil, at the armature front end one groove is arranged, the valve sealing gasket is between armature and valve, the valve sealing gasket comprises the seal head of the platform shape of the base that is positioned at groove and projection, and the diameter of seal head is less than the diameter of base, greater than the diameter of the pore of valve.
This utility model electric sphygmomanometer electromagnetic valve, wherein the valve sealing gasket is a rubber bodies.
This utility model electric sphygmomanometer with electromagnetic valve in use, its valve sealing gasket base is fixed in the groove of armature front end by glue, seal head stretches out slightly forward, when travelling forward under the effect of armature at hot-wire coil, seal head tightly is attached on the valve, because the seal head diameter is less, easily compression, it is more reliable to make that valve can sealedly get, and the while can compensate the foozle of product again, thereby has improved the global reliability of product.
Description of drawings
Fig. 1 is the STRUCTURE DECOMPOSITION figure of existing electromagnetic valve;
Fig. 2 is the enlarged drawing of existing electromagnetic valve valve sealing gasket;
Fig. 3 is the STRUCTURE DECOMPOSITION figure of this utility model electric sphygmomanometer with electromagnetic valve;
Fig. 4 is the enlarged drawing of this utility model electric sphygmomanometer with electromagnetic valve valve sealing gasket.
The specific embodiment
For further specifying this utility model, specifically set forth with the following Examples:
With reference to figure 1, Fig. 2 and Fig. 4, existing electromagnetic valve, the sealing gasket 1 at its valve place is a slab construction, this structure is unfavorable for valve 4 is sealed, and this utility model electric sphygmomanometer electromagnetic valve, comprise valve sealing gasket 1, armature 2, coil 3 and valve 4, described armature 2 places described coil 3, at described armature 2 front ends one groove 21 is arranged, described valve sealing gasket 1 is between described armature 2 and described valve 4, described valve sealing gasket 1 comprises the seal head 12 of the platform shape of the base 11 that is positioned at described groove 21 and projection, and the diameter of described seal head 12 is less than the diameter of described base 11, greater than the diameter of the pore of described valve 4.Described electromagnetic valve valve sealing gasket 1 is a rubber bodies, by the rubber pattern technological forming.
As shown in Figure 3, by glue be fixed in the groove 21 of armature 2 front ends in the base 11 of the valve sealing gasket of electromagnetic valve this utility model electric sphygmomanometer, seal head 12 stretches out slightly forward, when armature 2 travels forward under the effect of hot-wire coil 3, seal head 12 tightly is attached on the valve 4, because the seal head diameter is less, easily compression, it is more reliable to make that valve can sealedly get.
Above-described embodiment is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; relate under the scheme prerequisite not breaking away from this utility model; various modification and improvement that those skilled in the art make the technical solution of the utility model; all should fall into protection domain of the present utility model; the technology contents that this utility model is asked for protection all is documented in claims.
