[0003] In the above structure, only one raw material bottle is usually provided, and only one pressing pump head is provided correspondingly. However, with the continuous upgrading of market demand, for example, in the field of daily chemical cosmetics, the raw material ingredients of the products used by consumers are increasing. Some of the high-end active ingredients are not allowed to be pre-mixed during the spraying process in order to ensure the efficacy during use, and must be mixed by hand after spraying. In this case, if spraying is carried out through only one channel, it must be pre-mixed during the spraying process, so it is difficult to obtain the desired efficacy.

[0004] To this end, for some high-end cosmetics, designers have begun to try to separate the various high-end active ingredients in the raw materials into different raw material bottles, and hope to spray the raw materials through multiple independent channels.

[0005] Therefore, developing a pump head with multiple channels independent of each other has become an urgent problem to be solved.

[0006] Furthermore, in order to improve efficiency, it is required to be able to eject the multiple raw materials synchronously and independently through multiple channels when the multiple raw materials are allowed to be pre-mixed after being ejected separately.

[0007] In the case where multiple raw materials cannot be mixed in advance after being ejected separately, it is required to eject multiple raw materials step by step and independently through multiple channels. Utility Model Content

[0130] The pump core 62 is installed inside the gas seal 64 in such a manner that it can reciprocate along the Z direction relative to the gas seal 64, and is formed with a raw material suction end 621 on the Z2 side, and the peripheral wall of the raw material suction end 621 is formed with a raw material suction port 6211 for sucking raw materials, and is formed with a substantially cylindrical core cavity 622 extending along the Z direction, and a raw material outflow port 623 at the end on the Z1 side, the raw material outflow port 623 is enlarged relative to the diameter of the core cavity 622, and accommodates the second connection port 52 of the above-mentioned connector 5, and a compression spring 63 is installed between the outer peripheral surface of the raw material outflow port 623 and the gas seal 64, and the compression spring 63 supports the pump core 62 to reciprocate along the Z direction relative to the pump housing 61. A "feeding channel L1" for the flow of raw materials is formed from the pump housing opening 611 through the pump cavity of the pump housing 61 and the core cavity 622 of the pump core 62.

[0131] like Figure 4 As shown, the above-mentioned feeding channel L1, connecting channel L2 and discharging channel L3 are connected in sequence to form a channel L for the flow of raw materials.

[0132] In order to firmly fix the nozzle 3, connector 4, connecting head 5 and raw material pump 6 constituting the channel L to each raw material bottle 9 and the outer bottle 8, an outer ring 7 is arranged between the raw material pump 6 and the four raw material bottles 9 and the outer bottle 8, and the four raw material pumps 6 are installed and fixed to each raw material bottle 9 and the outer bottle 8 through the outer ring 7.

[0133] Outer ring 7 Figure 6 The bottom wall 71 is shown as follows: the bottom wall 71 is square and has four evenly distributed circular mounting holes 711 corresponding to the four raw material pumps 6. The four mounting holes 711 are respectively inserted into the Z1 side ends of the four raw material pumps 6. Pump sealing ribs 74 for airtightly fixing with the raw material pumps 6 are respectively extended from the four mounting holes 711 toward the Z1 side and the Z2 side; the peripheral wall 72 includes an upper peripheral wall 721 extending from the peripheral edge of the bottom wall 71 toward the Z1 side, the upper peripheral wall 721 is for the pressing cover 2 to be embedded, and a lower peripheral wall 722 extending from the peripheral edge of the bottom 71 toward the Z2 side, the lower peripheral wall 722 is engaged with the outer peripheral surface of the outer bottle mouth 81 of the outer bottle 8 to be fixed to the outer bottle 8; the bottle sealing rib 73 (refer to Figure 3 ), the bottle sealing rib 73 extends from a portion of the bottom wall 71 that is radially inward of the peripheral wall 72 toward the Z2 side and is tightly attached to the inner peripheral surface of the raw material bottle 9; the pump sealing rib 74 (refer to Figure 3 ), the pump sealing rib 74 is airtightly fixed to the pump housing 61 of the raw material pump 6; the position anti-deviation protrusion 75 (refer to Figure 3 ), the position deviation prevention protrusion 75 extends from the position of the bottom wall 71 corresponding to the position deviation prevention mechanism 23 of the pressing cover 2 toward the Z1 side, and the cross section is formed into a cross shape corresponding to the position deviation prevention mechanism 23 (refer to Figure 6 ). After being assembled, the pressing cover 2 , the nozzle 3 , the connector 4 , the connecting head 5 and the raw material pump 6 are fixed in the mounting hole 711 of the bottom wall 71 of the outer ring 7 .

[0134] Next, the assembled outer ring 7 is Figure 3 As shown, it is fixedly installed on the raw material bottle 9 and the outer bottle 8.

[0135] like Figure 3 As shown, the outer bottle 8 includes an outer bottle body 82 and an outer bottle mouth 81 that decreases in diameter from the outer bottle body 82 toward the Z1 side, the bottom wall 71 of the outer ring 7 blocks the outer bottle mouth 81 and the lower peripheral wall 722 is engaged with the outer peripheral surface of the outer bottle mouth 81. In this way, the outer ring 7 is fixed to the outer bottle 8.

[0136] In addition, the plurality of raw material bottles 9 are respectively formed to include a raw material bottle body 91 and a raw material bottle mouth 92 that is reduced in diameter from the raw material bottle body 91 toward the Z1 side. The bottom wall 71 of the outer ring 7 blocks the raw material bottle mouth 92 of the raw material bottle 9 while the bottle sealing rib 73 is tightly attached to the inner surface of the raw material bottle body 91 in an airtight manner. In this way, the outer ring 7 is airtightly fixed to each raw material bottle 9. In addition, a piston 10 is installed at the bottom of the raw material bottle 9, and the piston 10 is used to move toward the Z1 side to pump the raw material in the raw material bottle 9 toward the raw material pump 6.

[0137] Below, refer to Figure 4 , 5 The connection structures of the pressing cover 2 and the outer ring 7 , the outer ring 7 and the raw material pump 6 , the outer ring 7 and the outer bottle 8 , and each raw material bottle 9 are described in detail.

[0138] First, regarding the connection structure between the pressing cover 2 and the outer ring 7, as shown in FIG. Figure 4 As shown, the pressing cover 2 is constructed such that the cover peripheral wall 21 is partially embedded in the outer cover 7 along the Z direction, and the position deviation prevention structure 23 formed at the four corners of the pressing cover 2 is recessed in the center to form a position deviation prevention groove with a substantially cross-shaped cross section.

[0139] Correspondingly, Figure 6 As shown, position deviation preventing protrusions 75 extending from the bottom wall 71 toward the Z1 side and having a substantially cross-shaped cross section are formed at the four corners of the outer ring 7 .

[0140] In this way, when the pressing cover 2 is embedded in the outer ring 7, the anti-deviation protrusions 75 at the four corners of the outer ring 7 are respectively embedded in the four anti-deviation grooves of the pressing cover 7 to limit the movement of the pressing cover 2 relative to the outer ring 7 in the horizontal direction (i.e., the X direction and the Y direction).

[0141] In addition, four limiting ribs 76 extending toward the Z1 side are formed on each edge of the bottom wall 71 of the outer ring 7. These limiting ribs 76 are formed at positions corresponding to the peripheral wall 21 of the pressing cover 2 in the horizontal direction. Their dimensions in the Z direction are the same and are both smaller than the dimensions of the peripheral wall 72 in the Z direction.

[0142] Next, regarding the connection structure between the outer ring 7 and the raw material pump 6, as shown in FIG. Figure 6 As shown, four circular mounting holes 711 for mounting the raw material pump 6 are formed through the bottom wall 71 of the outer ring 7 , and pump sealing ribs 74 extending toward the Z1 side and the Z2 side are formed at the edges of the mounting holes 711 .

[0143] like Figure 4 As shown, from the radial outer side to the radial inner side, the pump housing 61 of the raw material pump 6 is fixed to the pump sealing rib 74 in an airtight manner from the radial inner side as described above (refer to Figure 3), the gas seal 64 is airtightly fixed to the pump housing 61 from the radial inner side, and the pump core 62 is airtightly attached to the gas seal 64 from the radial inner side and can reciprocate along the Z direction relative to the gas seal 64. Moreover, as described above, a compression spring 63 is also provided between the raw material outflow port 623 of the raw material pump 6 and the gas seal 64. In this way, the raw material pump 6 is airtightly fixed to the outer ring 7.

[0144] Furthermore, regarding the connection structure between the outer ring 7 and the outer bottle 8, as shown in FIG. Figure 6 As shown, the peripheral wall 72 of the outer ring 7 includes an upper peripheral wall 721 for the pressing cover 2 to be embedded and a lower peripheral wall 722 for being engaged with the outer peripheral surface of the outer bottle mouth 81 of the outer bottle 8.

[0145] The cover peripheral wall 21 of the pressing cover 2 slightly contacts the upper peripheral wall 721 of the peripheral wall 72 of the outer ring 7 and can move relative to the upper peripheral wall 721 along the Z direction. Although not shown, the lower peripheral wall 722 of the outer ring 7 is engaged with the outer peripheral surface of the outer bottle mouth 81 of the outer bottle 8.

[0146] Moreover, in the outer ring 7 Figure 3 As shown, a bottle sealing rib 73 is formed, and the bottle sealing rib 73 is tightly attached to the inner peripheral surface near the bottle mouth of the raw material bottle 9 to fix the outer ring 7 to the raw material bottle mouth 91 of the raw material bottle 9 and to airtightly seal the raw material bottle mouth 91. In this way, the outer ring 7 is fixed to the outer bottle 8 and airtightly fixed to the raw material bottle 9.

[0147] (Structure of push-type pump head)

[0148] In the raw material container 1 as described above, Figure 4 As shown, the push-type pump head is composed of a push cover 2, a nozzle 3, a connector 4, a connection head 5, a raw material pump 6, and an outer ring 7 in order from the Z1 side to the Z2 side.

[0149] In the push-type pump head, as shown by the arrows in the figure, the feed channel L1 in each raw material pump 6, the connection channel L2 formed by connecting each pair of connectors 4 and the connector 5, and each discharge channel L3 in the nozzle 3 are connected in sequence to form a channel L. The raw materials in each raw material bottle 9 are ejected through the channel L formed in the above manner.

[0150] (Workflow of the push-type pump head according to the first embodiment)

[0151] After the user installs the above-structured push-type pump head on the outer bottle 8 and the raw material bottle 9, when the user presses the push cover 2 downward (Z2 side) with a finger, the push rib 22 presses on the connector body 41 of the connector 4, so that the connector 4 moves toward the Z2 side until the second connection port 52 of the connector 5 is inserted into the raw material outflow port 623 of the pump core 62 and communicates with the pump core 62. In this way, the above-mentioned channel L is connected.

[0152] Then, under this action, the pump core 62 moves toward the Z2 side relative to the pump housing 61 and presses the compression spring 63. In this process, as the pump core 62 moves toward the Z2 side, the pressure in the pump chamber surrounded by the pump core 62 and the pump housing 61 continues to increase until the pressure is greater than the pressure of the core chamber 622 and greater than the pressure of the raw material bottle 9, that is, the pressure difference between the pump chamber and the core chamber is positive and the pressure difference between the pump chamber and the raw material bottle is positive.

[0153] At this time, the one-way valve 612 at the opening 611 of the pump housing is closed, and the raw material in the raw material bottle 9 no longer flows into the pump cavity. At the same time, the raw material suction port 6211 of the pump core 62 is opened, and the raw material in the pump cavity flows into the core cavity 622 through the raw material suction port 6211, and continues to be sprayed out from the nozzle 3 through the channel L.

[0154] When a certain amount of raw material is sprayed from the nozzle 3 and the pressing cover 2 moves to the position abutting against the limiting rib 76, the user releases the finger to release the pressing cover 2, and the pressing cover 2 will drive the pump core 62 to move toward the Z1 side under the action of the restoring force of the compression spring 23. In this process, the pressure in the pump cavity surrounded by the pump core 62 and the pump housing 61 is continuously reduced until the pressure is less than the pressure in the raw material bottle 9 and less than the pressure in the core cavity, that is, the pressure difference between the pump cavity and the core cavity is negative and the pressure difference between the pump cavity and the raw material bottle is negative.

[0155] At this time, the one-way valve 612 at the opening 611 of the pump housing is opened, and the raw material in the raw material bottle 9 flows into the pump chamber through the opening 611 of the pump housing. At the same time, the raw material suction port 6211 of the pump core 62 is closed, and the raw material in the pump chamber no longer enters the core chamber 622 through the raw material suction port 6211. Raw material is continuously accumulated in the pump chamber to prepare for the next supply of raw material to the nozzle 3.

[0156] In this way, a certain amount of raw material can be ejected by one pressing.

[0157] In this embodiment, if Figure 4 As shown, the connector body 41 of the connector 4 for forming four connecting channels L2 is integrated and the size of the limiting ribs 6 in the Z direction for limiting the moving range of the pressing cover 2 is the same, so the user only needs to press the pressing cover 2 to open the four channels L independently and synchronously to spray the raw materials. In this way, multiple raw materials can be sprayed efficiently on the basis of spraying multiple raw materials separately. Therefore, it is well applicable to the situation where multiple raw materials are prohibited from being pre-mixed.

[0158] (Modification 1 of Raw Material Container of First Embodiment)

[0159] In the above-mentioned embodiment, the portion of the connector 4 used to form the connection channel L2 is integrated, and the dimensions of the four limiting ribs 76 in the Z direction that limit the range of movement of the pressing cover 2 toward the Z2 side are the same, but the utility model is not limited to this. The portion of the connector 4 used to form the connection channel L2 can also be separated, and the dimensions of the four limiting ribs 76 in the Z direction are different.

[0160] Since the part of the connector 4 used to form the connection channel L2 is split and the dimensions of the four limiting ribs 76 in the Z direction are different, the user can select to press any number of the pressing cover parts step by step and independently according to different effects to spray out different amounts of raw materials.

[0161] (Variation 2 of Raw Material Container of First Embodiment)

[0162] In the above embodiment, a plurality of connection channels L2 are arranged at equal intervals along the circumference of the connector 4, but the raw material container of the present invention is not limited thereto, and when there are still a plurality of connection channels L2 arranged along the circumference of the connector 4, multiple layers are stacked along the height direction of the connector 4. In this way, even when the number of channels is insufficient to arrange one layer along the circumference of the connector 4, it can be well applied.

[0163] (Raw Material Container of Second Embodiment)

[0164] In this embodiment, except that the pressing cover is divided into four parts and each part is directly connected to the raw material pump without a connector and a connector, the rest is the same as the first embodiment. Figures 7 to 9 A description will be given of a case where the pressing cover 2A in the raw material container of the second embodiment is communicated with and connected to four raw material pumps 6 to form four independent and separate channels LA.

[0165] like Figure 7 , 8 As shown, the pressing cover 2A is integrally embedded in the upper peripheral wall 721A of the outer ring 7 and is divided into four pressing cover sections 2A1. Fig. 9 As shown, a pressing cover connecting portion 2A12 extending along the Z direction and a pressing cover ejection portion 2A11 extending from the Z1 side end of the pressing cover connecting portion 2A12 to the X2 side are formed. A discharge channel L3A is formed in the pressing cover ejection portion 2A11 and the pressing cover connecting portion 2A12.

[0166] Correspondingly, a core cavity 622A is formed in each raw material pump 6A, and a supply channel L1A is formed in the core cavity 622A of the raw material pump 6A. The supply channel L1A and the discharge channel L3A are connected in sequence to form a channel LA.

[0167] In this embodiment, if Figure 7 As shown, four sets of channels LA are formed.

[0168] In addition, if Figure 8 As shown, four limiting ribs 76A are formed on the outer ring 7A, and the dimensions of these limiting ribs 76A in the Z direction are different according to the required pressing amounts of various raw materials.

[0169] According to the above-mentioned structure, since the connector and the connection head are omitted, the number of parts can be reduced and the cost can be reduced.

[0170] In addition, since the four groups of channels LA are independent of each other, each of which is composed of the push cover ejection portion 2A11 of the push cover segment 2A1, the push cover connection portion 2A12, and the core cavity 622A, compared with the first embodiment, the user can press any one, two, three, or four push cover segments 2A in the push cover 2A to activate one group of channels LA, two groups of channels LA, three groups of channels LA, or four groups of channels LA.

[0171] In this way, the four channels LA can be connected synchronously and independently as in the first embodiment, or the four channels LA can be connected step by step and independently as in the first embodiment. Thus, the connection of each channel LA can be made more flexible.

[0172] (Variation 1 of Raw Material Container of Second Embodiment)

[0173] As described above, in the second embodiment, the four-group push cover 2A is divided into four push cover sections 2A1, and a discharge channel L3A connected to the raw material pump 6A is formed in each of the four push cover sections 2A1. However, the present invention is not limited thereto, and the portion of the push cover 2A used to form the four discharge channels L3A may also be integrated.

[0174] In this way, by integrating the portion of the pressing cover 2A for forming the four discharge channels L3A, the four channels LA can be opened synchronously to pump the raw material. Thus, the efficiency of ejecting the raw material can be improved on the basis of ejecting the raw material separately.

[0175] Furthermore, the four stopper ribs 76A in the outer ring 7A are formed to have the same dimensions in the Z direction.

[0176] (Variation 2 of Raw Material Container of Second Embodiment)

[0177] As described above, in the second embodiment, the pressing cover 2A is divided into four pressing cover sections 2A1, and the corresponding limiting ribs with the same size in the Z direction are formed in each pressing cover section 2A1. However, the present invention is not limited thereto, and the sizes of the limiting ribs in the Z direction may also be formed to be different from each other.

[0178] In this way, the dimensions of the limiting ribs in the Z direction are formed to be different through the four corresponding split pressing cover sections 2A1, and the pressing cover sections 2A1 can be pressed independently and stepwise to connect the four channels LA.

[0179] Therefore, the number of pressing cover sections 2A1 to be pressed can be flexibly selected according to different effects, thereby spraying different amounts of raw materials.

[0180] Although the various embodiments of the present invention have been described above, in addition to the above embodiments, new embodiments can be obtained by combining elements of the above embodiments without departing from the spirit of the invention of the present invention.

[0181] In the above embodiments, four groups of channels are formed, but the present invention is not limited thereto, and other groups of channels may also be formed.

[0182] In the above embodiment, the connector is formed to have an octagonal cross section, but the present invention is not limited thereto, and the connector may also be formed to have other cross-sectional shapes.

[0183] In the above embodiment, the anti-position deviation structure 23 in the pressing cover 2 and the anti-position deviation protrusion 75 of the outer ring 7 are both formed with a cross-shaped cross section, but the utility model is not limited to this, and they can also be formed with other cross-sectional shapes.

[0184] In the above embodiment, the mounting hole 711 of the outer ring 7 for mounting the raw material pump 6 is formed in a circular shape, but the present invention is not limited thereto and may be formed in other shapes.
