As shown in fig. 3, the outer wall of the middle shell 4 is axially provided with a middle shell groove 401, and the leg 101 is embedded in the middle shell groove 401. The outer wall of the bottom shell 5 is provided with a bottom shell groove 501 along the axial direction, and the support legs 101 are embedded in the bottom shell groove 501. The supporting legs 101 are embedded in the middle shell 4 and the bottom shell 5 and do not protrude out of the middle shell or the bottom shell, so that the appearance is improved, and the upper cover is prevented from being damaged by external equipment. The middle shell groove 401 and the bottom shell groove 501 can play a role in guiding and positioning at the same time, so that the support legs can be quickly positioned and guided.

Bottom shell groove 501 is provided with sand grip 502, uses as the antislip strip, prevents to rock from side to side, also improves the smooth degree as the direction when landing leg 101 gets into bottom shell groove 501.

In use, the leather cup (not shown), the gasket 2 (shown in fig. 3), the pressing sheet 3 (shown in fig. 3), the bracket (not shown), the rotating frame (not shown) and other components, the middle shell 4 and the bottom shell 5 are installed, then the upper cover 1 penetrates the support legs 101 into the middle shell groove 401 of the middle shell from the upper part of the middle shell 4 and extends along the middle shell groove 401 into the bottom shell groove 501, so that the wrapping part 102 is positioned in the groove 503, the stability among the components is ensured, and the pre-installation of the product is formed.

Namely: after the internal product is placed stably, the positions of all internal parts are locked after the upper cover is pressed.

A pump comprising a pre-assembled, tube-controlled pump housing as described above, and further comprising a motor (not shown) mounted on the lower portion of the bottom shell.

In addition, after the pump is installed, the pump is installed in a massage chair for use, as shown in fig. 4 and 5, the upper cover 1 is provided at an upper portion thereof with a gas outlet portion 104 for delivering gas to a working position of the massage chair for massage, a gas release portion 105 for releasing excess internal gas, and a gas outlet pipe 106 for delivering internal gas toward the gas outlet portion 104 or toward the gas release portion 105, one end of the gas outlet pipe 106 is connected to the inside of the pump, and the gas outlet portion 104 and the gas release portion 105 are both communicated to a gas outlet end of the gas outlet pipe 106.

As shown in fig. 6, the air-release diaphragm 108 is arranged inside the air-release portion 105, the air-release diaphragm 108 can block the air hole of the air-release portion 105, when the air pressure inside the pump is normal, the air hole is always blocked by the air-release diaphragm 108, so that other air can be only delivered to the air-release portion 104, that is, air release is not needed; the other side of the air release membrane 108 is provided with an elastic element 110 for pressing the air release membrane, and the opening and closing of the air release membrane is controlled by the elasticity of the air release membrane.

Further, the outer end of the air release portion 105 is provided with an air release hole 113 for releasing excess air when the air pressure is too high. Of course, when the air release diaphragm 108 is opened, the air release hole 113 can release air, otherwise the air release hole 113 can not release air.

Fig. 6 is a partially enlarged view of fig. 5, in which the elastic member 110 is not shown, and an annular plate 107 is disposed at the connection between the air release portion 105 and the air outlet pipe 106, and the air release diaphragm 108 presses on the annular plate 107 to block the air hole, so that no air flows through the air hole when the air pressure is normal.

Further, an accommodating ring groove 1081 is formed in one side surface of the air leakage membrane 108, the accommodating ring groove 1081 is pressed on the ring plate 107, wherein the accommodating ring groove 1081 is shaped like a wavy line, and the structure of the wavy line can enhance the sealing effect of the position, so that the position is sealed when air pressure is normal, namely air leakage is needed, and the work of the massage position is prevented from being influenced.

One side surface of the air leakage membrane 108 is provided with a convex ring 1082, and the convex ring 1082 can extend into the air hole of the air leakage part 105, so that the sealing effect is further enhanced.

A stop ring 1083 is arranged at the outer edge of the other side of the air-release membrane 108, and one end of the elastic member 110 abuts against the stop ring 1083, so that the elastic member is prevented from deflecting to affect the sealing effect. The center of the other side of the air-release diaphragm 108 is provided with a guide block 1084, the guide block 1084 is disposed on the central axis of the elastic member 110 for guiding on one hand and further positioning the elastic member on the other hand, and the elastic member in this embodiment is a spring, so as to enhance the stability of the spring.

The inner part of the outer end of the air release part 105 is provided with a block 112, one end of an elastic piece 110 is abutted against the air release membrane 108, the other end of the elastic piece is abutted against the inner part of the block 112, and parts at two ends extrude the spring, so that the spring always has the tendency of extension, the air release membrane is tightly pressed on the air hole, and the air release is ensured not to release air; the air release hole 113 is opened on the block 112, and when air is released, the other air is discharged through the air release hole 113. One side of the blocking piece 112 is provided with a steel ball 111, the end of the elastic piece 110 is abutted against the steel ball 111, and the arrangement of the steel ball enables the spring to have a buffering force, so that the phenomenon that the air leakage diaphragm is damaged due to too large rebound force is avoided.

During the use, the massage position is carried from portion 104 of giving vent to anger to the gas that inside leather cup 7 and swinging boom 6 produced, if inside produced gas pressure is great, can lead to the damage of massage position and pump, therefore, when pressure is great, the ventilative diaphragm 108 of atmospheric pressure impact, when atmospheric pressure is greater than the dynamics of elastic component 110, atmospheric pressure will lose heart diaphragm 108 and break away, make the spring compression, it leaves the gas pocket to lose heart diaphragm 108, gas is discharged from losing heart diaphragm's edge gap, then through losing heart hole 113 discharge, inside atmospheric pressure is normal after, atmospheric pressure is less than the spring force, the gas pocket is blocked up again to the diaphragm that loses heart.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
