DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] refer to Figure 1-2 As shown, the utility model provides a press-type dual-liquid micro pump head, comprising: a daily chemical bottle body 1 with two storage bins, a pump head body 5 with a pump liquid channel is provided on the daily chemical bottle body 1, a detachable rotating seat 4 is provided on the daily chemical bottle body 1, and two suction pieces are symmetrically penetrated on the rotating seat 4 and extend to the two storage bins respectively, the pump head body 5 is rotatably installed on the top of the rotating seat 4, and a hollow connector 9 is eccentrically provided at the bottom of the pump head body 5, one end of the hollow connector 9 is connected to the pump liquid channel in the pump head body 5, and the hollow connector 9 is connected to the end portions of the two suction pieces in turn based on rotation.

[0024] Combine Figure 2 As shown, the suction piece includes a plug 8 and a suction tube 7 plugged into the plug 8 . The two plugs 8 are symmetrically arranged on the rotating base 4 , and the two suction tubes 7 are respectively arranged on both sides of the partition 6 .

[0025] As mentioned above, when using the daily chemical bottle body 1, pump head body 5, rotating seat 4 and two suction pieces provided by the utility model, the suction pipe 7 in the suction piece is detachably plugged into the rotating seat 4 through the plug 8, and the rotating seat 4 is detachably installed at the bottle mouth position of the daily chemical bottle body 1. At this time, the two suction pipes 7 are respectively plugged into the two storage bins. When the pump head body 5 is rotated, the hollow connector 9 on the pump head body 5 switches between the two plugs 8. After the hollow connector 9 is in one of the plugs 8, the pump head body 5 is pressed, and the liquid in the corresponding storage bin is sprayed outward through the pump head body 5. When the hollow connector 9 is switched to the other plug 8, the pump head body 5 is pressed, and the liquid in the other storage bin is sprayed outward through the pump head body 5.

[0026] Further, in order to facilitate the formation of a storage bin for accommodating two liquids in the daily chemical bottle body 1, refer to Figure 2 and Figure 4As shown, the daily chemical bottle body 1 is further provided with a partition 6 that separates the two storage compartments. Two suction members are respectively arranged on either side of the partition 6, and a sealing member is provided between the rotating base 4 and the bottle mouth 2 for sealing. The partition 6 can form a single daily chemical bottle body 1 into two storage compartments for storing two liquids, thereby reducing the packaging cost of the device and the storage area occupied by the device.

[0027] In this utility model, combined with Figure 2 As shown, the bottom of the pump head body 5 of this embodiment is further provided with an installation chamber 11 for accommodating the hollow connector 9 , and a spring 10 abutting against the hollow connector 9 is provided in the installation chamber 11 .

[0028] As mentioned above, when using the spring 10 provided by the present invention, the spring 10 is hidden and installed between the pump head body 5 and the hollow joint through the installation chamber 11. When the hollow joint is not docked with the plug 8, the hollow joint is forced to retract into the installation chamber 11, thereby reducing the wear of the hollow joint when switching between the two plugs 8 and improving the service life of the hollow joint. When the hollow joint is outside the plug 8, the hollow joint is automatically pushed into the plug 8 under the elastic force of the spring 10, and the elastic force of the spring 10 can prevent the hollow joint from detaching from the plug 8, thereby improving the sealing of the docking between the hollow joint and the plug 8.

[0029] Further, in order to facilitate the liquid circulation of the hollow connector 9 during the activity, refer to Figure 2 As shown, the hollow connector 9 is further provided with a hose 12 communicated with the pump liquid channel, and the spring 10 is sleeved on the outside of the hose 12. The hose 12 can avoid interference with the expansion and contraction of the hollow connector 9.

[0030] In this utility model, combined with Figure 2 As shown, the bottom of the rotating seat 4 of this embodiment is also provided with an internal threaded joint 3 connected to the daily chemical bottle body 1, and the bottle mouth of the daily chemical bottle body 1 is provided with a bottle mouth 2 that matches the internal threaded joint 3, and the internal threaded joint 3 is screwed on the bottle mouth 2;

[0031] A first rotation groove 15 for accommodating the rotation of the pump head body 5 is formed on the inner wall of the top end of the rotation seat 4 , and a second rotation groove 16 for accommodating the rotation of the rotation seat 4 is formed on the inner wall of the top end of the internal threaded joint 3 .

[0032] As described above, when using the internal threaded joint 3 provided by the present invention, after the two straws 7 are respectively inserted into the two storage bins, the rotating base 4 is allowed to fall onto the bottle mouth 2. At this time, the internal threaded joint 3 is rotated to fasten the rotating base 4 to the bottle mouth 2. By rotating the internal threaded joint 3, the rotating base 4 can be prevented from rotating when installed on the bottle mouth 2, so that the two straws 7 can always be placed in the two storage bins.

[0033] Furthermore, in order to avoid mixing of the liquids in the two storage tanks, refer to Figure 2-3 As shown, the sealing member includes a gasket 13 having two symmetrical through-holes 14 extending therethrough. The two through-holes 14 are disposed on either side of the partition 6, with the bottle mouth 2 and one end of the partition 6 abutting against the gasket 13. When the gasket 13 is positioned between the rotating bases 4, the two through-holes 14 on the gasket 13 are located in the respective storage bins. This prevents the mixing of the liquids in the two storage bins through the gasket 13, while facilitating the entry of the straw 7 into the corresponding storage bin through the through-holes 14.

[0034] Further, in order to facilitate the positioning of the sealing gasket 13, refer to Figure 2-4 As shown, the rotating base 4 is further provided with a positioning post 17 for positioning the sealing gasket 13 and the bottle mouth 2. The sealing gasket 13 is penetrated by a positioning hole 18 extending to the bottle mouth 2, and one end of the positioning post 17 is inserted into the positioning hole 18. When the positioning post 17 is inserted into the positioning hole 18, the position of the sealing gasket 13 can be positioned so that the two through holes 14 on the sealing gasket 13 are respectively located on both sides of the partition 6. After the rotating base 4 is stably installed on the bottle mouth 2 and the daily chemical bottle body 1 is inverted, the liquids in the two storage bins are prevented from mixing.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
