Abstract

A micro-press-force emulsion pump comprises a press head, a thread, a body, a main column, an auxiliary column, a piston, a pressure spring, a glass ball and an outer sleeve. A spring seat with a lower opening is formed in the lower end of the auxiliary column. Multiple rib plates are arranged at the top of a one-way valve seat. The piston comprises an inner cylindrical sleeve, an outer cylindrical sleeve and an annular seat plate for connecting the inner cylindrical sleeve with the outer cylindrical sleeve. The two ends of the pressure spring are provided with supporting devices. The upper end of the pressure spring is inserted in the spring seat. The supporting devices are attached to a top plate of the spring seat. The supporting device at the lower end of the pressure spring is matched with the upper ends of the rib plates. The pressure spring is assembled in the body without being prepressed, and the axis of the pressure spring coincides with the axis of the body. The press head is moved downwards, the main column and the auxiliary column are moved downwards and compress the pressure spring, and in the moving process, the axis of the pressure spring coincides with the axis of the body. By the adoption of the micro-press-force emulsion pump, the defects that a pressure spring cannot be compressed along the axis and labor is wasted in the prior art are overcome; and assembly is convenient, and labor is saved for press operation.

When initially pressure spring being placed on gusset, the axis of pressure spring and the dead in line of body.

Described one is micro-by power emulsion pumps, and its special character is: described bracing or strutting arrangement is a bracing ring arranging spring end, and the number of active coils of bracing ring and pressure spring is fitted.

Described one is micro-by power emulsion pumps, and its special character is: also comprise a curvilinear figure seat, one end of curvilinear figure seat is connected with bracing ring, the other end is unsettled; Curvilinear figure seat and bracing ring are in one plane; Curvilinear figure seat is relative with the inner chamber of pressure spring.

Described one is micro-by power emulsion pumps, and its special character is: have a sliding bevel, described sliding bevel and upper piston position inwall bearing fit outside the upper end of inner cylindrical cover;

Described outer cylindrical puts, lower end outside is provided with sliding bevel and lower slider inclined-plane, upper and lower sliding bevel and described main body inner wall bearing fit.

The present invention is a kind of micro-by power emulsion pumps, and owing to adopting such structure, pressure spring is assembled in body, does not need precompressed, can ensure the axis of pressure spring and the dead in line of body; Head moves down, and major-minor post moves down and compressed pressure spring, and in moving process, the axis of pressure spring and the axis of body keep overlapping; Overcome in prior art, pressure spring can not along the defect of axis compression, effort; Have easy to assembly, press laborsaving, pump effective.

Detailed description of the invention

Below in conjunction with accompanying drawing, the invention will be further described.

As shown in Figure 1 and Figure 2, a kind of micro-by power emulsion pumps, comprise head 1, thread 2, body 3, principal post 4, subpost 5, piston 6, pressure spring 7, glass bead 8 and outer sleeve body 9, head 1 has feed liquor interface 1A and liquid outlet channel 1B; Guide pipe 21 on the top board of thread 2; There is lower piston position 51 on upper piston position 41, subpost 5 lower end of principal post 4, and there is pod apertures lower piston position 51, and there is the spring perch 52 of under shed the lower end of subpost 5; There is one-way valve seat 31 body 3 lower end, and some gussets 32 are arranged at the top of one-way valve seat 31; The annulus seat board 63 that described piston 6 comprises inner cylindrical cover 61, the outer cylindrical cover 62 of hyperbola is connected with by inside and outside cylindrical sleeve; With upper piston position 41 inwall bearing fit outside the upper end of described inner cylindrical cover 61; The upper end of principal post 4 is connected with the feed liquor interface 1A of head with guide pipe 21 through thread 2, being connected with principal post 4 on subpost 5;
