Specific embodiments

[0027] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0028] It should be noted that in the description of the present utility model, "upper", "lower", "top", "bottom", the orientation or positional relationship is based on the orientation or positional relationship shown in the attached drawings. It should be understood that these orientation terms are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. Figure 1 In an embodiment, as shown in and, the pressing type liquid pump of this embodiment includes:

[0029] In an embodiment, as Figure 1 and Figure 2 shown, the pressing type liquid pump of this embodiment includes:

[0030] A main body 100 that can be assembled to the outlet of the container, and a first pump body 130 and a second pump body 140 that are parallel and penetrate through the main body 100 are arranged inside the main body 100, and a straw 400 that can extend into the bottom of the container is connected to the liquid inlet end of the first pump body 130.

[0031] Among them, the straw 400 can be integrally connected to the first pump body 130 or can be connected by a sleeved manner.

[0032] The pressing liquid discharging assembly is detachably assembled with the main body 100 and is used for simultaneously pressing the liquid discharging ends of the first pump body 130 and the second pump body 140 and discharging the liquid discharged from the first pump body 130 and / or the second pump body 140.

[0033] It should be noted that the first pump body 130 and the second pump body 140 are arranged in parallel, so the direction in which the pressing liquid discharging assembly presses the first pump body 130 and the second pump body 140 also needs to be parallel to the axis where the first pump body 130 and / or the second pump body 140 is located, and the two pump bodies can be pressed simultaneously.

[0034] In addition, when the container is in different states such as being placed vertically, tilted at different angles, or inverted, the first pump body 130 and the second pump body 140 can pump liquid alternately or simultaneously.

[0035] The main body 100 of the pressing liquid pump in this embodiment includes two pump bodies. The first pump body 130 is connected to the suction pipe 400 and can pump out the liquid in the container when the container is vertical or the tilt angle is not enough to separate the liquid inlet of the suction pipe 400 from the liquid. The second pump body 140 is not connected to the suction pipe 400, and its liquid inlet end is at the container outlet, and can pump out the liquid in the container when the container is inverted or tilted at a certain angle so that the liquid contacts the liquid inlet end of the second pump body 140.

[0036] In one embodiment, as Figure 2 and Figure 4 [ shown, the first pump body 130 and the second pump body 140 are vertically arranged in the main body 100. A pressing cavity 110 is provided at the top of the main body 100, and a mounting cavity 120 for connecting to the container outlet is provided at the bottom. The liquid discharging ends of the first pump body 130 and the second pump body 140 both extend out from the pressing cavity 110, the liquid inlet end of the first pump body 130 extends out from the mounting cavity 120, and the liquid inlet end of the second pump body 140 extends out from the mounting cavity 120 or is flush with the bottom of the mounting cavity 120.

[0037] The function of the mounting cavity 120 is to be assembled with the containers for containing fluids such as perfume, eau de toilette, hair gel, alcohol disinfectant, liquid medicine, shampoo, body wash, body lotion, hand sanitizer, and hairspray, so that the pressing liquid pump can pump out the fluids from each container.

[0038] It should be noted that if the first pump body 130 and the second pump body 140 are not vertically arranged in the main body 100, the position of the pressing cavity 110 is set in the corresponding pressing direction of the main body 100.

[0039] In this embodiment, the lengths of the liquid outlet ends of the first pump body 130 and the second pump body 140 extending from the pressing cavity 110 are equal, and are 1 to 2 times the length of the compression cavity of the first pump body 130 and / or the second pump body 140; when the liquid inlet end of the second pump body 140 extends from the installation cavity 120, the extension length is less than or equal to 1 mm.

[0040] When the liquid outlet ends of the first pump body 130 and the second pump body 140 extend from the pressing cavity 110, the extension lengths are greater than the length of the compression cavity, which can facilitate the pressing of the compression cavity of the pump body. When the liquid inlet end of the second pump body 140 extends from the installation cavity 120, the extension length is less than or equal to 1 mm, and the smaller the better. Optimally, the liquid inlet end of the second pump body 140 is flush with the bottom of the installation cavity 120, and the extension length of the liquid inlet end of the second pump body 140 from the installation cavity 120 is 0 mm. At this time, the second pump body 140 can maximize the pumping of the liquid in the container when the container is inverted, so that the liquid in the container will not remain and waste is avoided.

[0041] In an alternative embodiment, the pressing liquid outlet assembly is disposed on the top of the main body 100 and is slidably assembled in the pressing cavity 110. The pressing liquid outlet assembly includes a pressing block 200 and a pressing cover 300. The pressing cover 300 is rotatably assembled on the top of the pressing block 200, and the pressing block 200 is slidably assembled in the pressing cavity 110.

[0042] It should be noted that the pressing liquid outlet assembly can also be a hand-held pressing assembly, and the first pump body 130 and the second pump body 140 can be selectively pumped or pumped simultaneously through the hand-held pressing assembly.

[0043] Specifically, the pressing cover 300 is rotatably assembled on the top of the pressing block 200, and can adjust the liquid outlet direction when the liquid is discharged from the pressing liquid outlet assembly. The function of the pressing cavity 110 is to provide a space for the pressing block 200 to move up and down, so as to facilitate the pressing block 200 to drive the liquid outlet ends of the first pump body 130 and the second pump body 140 to squeeze downward, compress the springs of the first pump body 130 and the second pump body 140, and pump the liquid out from the liquid outlet ends of the first pump body 130 and / or the second pump body 140.

[0044] In one of the embodiments, the pressing block 200 is provided with a liquid outlet head 210 and a liquid pumping confluence channel. The liquid outlet ends of the first pump body 130 and the second pump body 140 are both communicated with the inlet of the liquid pumping confluence channel; the liquid outlet head 210 is disposed above the pressing block 200, and the outlet of the liquid pumping confluence channel is communicated with the liquid outlet head 210.

[0045] In this embodiment, the liquid outlet head 210 is columnar and is vertically fixed above the pressing block 200. The liquid outlet head 210 can also be an L-shaped liquid outlet head 210 with a pressing handle, which can directly discharge the liquid.

[0046] In one embodiment, the liquid pumping confluence channel is a U-shaped channel 220 with an opening facing downward. The pressing block 200 is further provided with a first assembly hole 230 and a second assembly hole 240 having the same aperture. The liquid outlet end of the first pump body 130 is inserted into the first assembly hole 230, and the liquid outlet end of the second pump body 140 is inserted into the second assembly hole 240. The two inlets of the U-shaped channel 220 are respectively communicated with the first assembly hole 230 and the second assembly hole 240, and the diameter of the U-shaped channel 220 is smaller than the aperture of the first assembly hole 230.

[0047] Specifically, since the diameter of the U-shaped channel 220 is smaller than the aperture of the first assembly hole 230, when the pressing block 200 slides downward, the U-shaped channel 220 will hold the pump body, preventing the pump body from sliding relative to the U-shaped channel 220.

[0048] It should be noted that the pump body in this embodiment can be a commonly used pressing pump on the market. Due to the presence of the blocking bead, there will be no backflow of the liquid inside the pump during pressing. Therefore, when the first pump body 130 and the second pump body 140 are pressed simultaneously, the liquid entering the U-shaped channel 220 from one pump body will not flow back through the other pump body that does not discharge liquid.

[0049] It should also be noted that the liquid pumping confluence channel can also be, but is not limited to, a Y-shaped channel, but the pump liquid needs to be confluent to the liquid outlet head through two branches.

[0050] As Figure 5 shown, the side wall of the pressing cover 300 is provided with a liquid outlet 310, and an L-shaped channel 320 is arranged inside the pressing cover 300. One end of the L-shaped channel 320 is sleeved on the liquid outlet head 210, and the other end of the L-shaped channel 320 is communicated with the liquid outlet 310.

[0051] Specifically, when the pressing cover 300 is pressed, no matter which pump body pumps out the liquid into the U-shaped channel 22, the liquid will enter the L-shaped channel 320 from the liquid outlet head 210 and then be discharged from the liquid outlet 310 on the side wall of the pressing cover 300.

[0052] The first pump body 130 of the pressing liquid pump in this embodiment is connected to the straw 400, and can pump out the liquid in the container when the container is vertical or the inclination angle is not enough to separate the liquid inlet of the straw 400 from the liquid. The second pump body 140 is not connected to the straw 400, and its liquid inlet end is communicated with the installation cavity 120 for fixedly connecting with the container, and can pump out the liquid in the container when the container is inverted or tilted at a certain angle so that the liquid contacts the liquid inlet end of the second pump body 140. The pressing liquid pump of the present utility model has a simple structure and can be applied to pump out the liquid in the container in the vertical state, inverted state and multi-angle inclined state of the container.

[0053] The present utility model also provides a pressing bottle, as Figure 6As shown in the figure, the pressing bottle includes a bottle body 500 and the pressing liquid pump in the above embodiment. The installation cavity 120 of the pressing liquid pump is fixedly connected to the outlet of the bottle body 500. The suction pipe 400 connected to the liquid inlet end of the first pump body 130 of the pressing liquid pump extends into the bottom of the bottle body 500. The side wall of the bottle body 500 includes a conical upper wall surface and a cylindrical lower wall surface. The included angle between the conical upper wall surface and the bottom surface of the bottle body 500 is 30° to 60°.

[0054] When the bottle body 500 is tilted until the liquid inlet of the suction pipe 400 cannot contact the liquid in the bottle, the included angle between the conical upper wall surface and the bottom surface of the bottle body 500 is beneficial to the liquid contacting the liquid inlet end of the second pump body 140.

[0055] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
