In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0024] It should be noted that, in the description of the present application, the orientation or positional relationship indicated by terms such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise stated, these orientation words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present application; the orientation words "inside and outside" refer to the inside and outside relative to the contour of each component itself.

[0026] See also Figure 1-Figure 4 The utility model provides a lotion pump, comprising: a cover cap 1, a pump chamber 2, an inner sleeve 3, a pump tube 4 and a pump head 5.

[0027] Among them, the cap 1 is a hollow structure with a frustoconical shape, and a cap opening 10 for screwing onto the bottle mouth is formed inside. A plurality of reinforcing ribs 11 are evenly arranged along the circumference on the outer side of the cap opening 10. The reinforcing ribs 11 are used to improve the structural strength of the cap 1 and enhance the pressure resistance. The cap 1 is screwed onto the bottle mouth for use.

[0028] The pump chamber 2 is through-hole and passes through the bottom of the cover cap 1. A boss 20 is formed at the upper end of the pump chamber 2. The boss 20 is recessed in the pump chamber 2. The inner sleeve 3 is arranged on the cover cap 1 and is plugged and fixed to the upper end of the pump chamber 2 so that the cover cap 1, the pump chamber 2 and the inner sleeve 3 are fixed as a whole.

[0029] The upper end surface of the boss 20 fits the lower end surface of the cap opening 10, and a sealing sheet 21 is sleeved on the pump chamber 2. The sealing sheet 21 is used to seal the bottle opening, thereby improving the sealing performance and preventing the liquid from flowing out.

[0030] The pump tube 4 is inserted into the pump chamber 2 from the inner sleeve 3, and the outer sleeve of the pump tube 4 is provided with a spring (not shown in the figure) which is elastically connected to the inside of the pump chamber 2. The pump tube 4 is communicated with the inside of the pump chamber 2, and the spring is sleeved on the pump tube 4. The upper end of the spring abuts against the pump tube 4, and the other end abuts against the inner wall of the pump chamber 2. Therefore, the pump tube 4 can move back and forth in the pump chamber 2 after being pressed, so that the internal space becomes smaller and the internal pressure becomes larger, thereby pressing the liquid in the bottle out.

[0031] The pump head 5 is plugged and fixed to the upper end of the pump tube 4, and a liquid outlet nozzle 50 is formed on the side of the pump head 5. The inside of the liquid outlet nozzle 50 is a liquid outlet channel 51, and the liquid outlet channel 51 is connected to the pump tube 4. The inner sleeve 3 is fitted on the upper edge of the boss 20 and is built into the cap 1.

[0032] In addition, a connecting portion 52 is formed at the bottom of the pump head 5, the upper end of the pump tube 4 is inserted and fixed in the connecting portion 52, and the connecting portion 52 is connected to the pump tube 4, and the liquid outlet nozzle 50 is connected to the connecting portion 52. The pump head 5 has a truncated cone structure in appearance, and the upper end of the pump head 5 is a large-diameter end, and the upper end of the cover cap 1 is a small-diameter end. A thread is also provided on the outer side of the connecting portion 52, and the cover cap 1 can be inserted into the inner sleeve 3 through the connecting portion 52 for threaded connection. Therefore, when not in use, the connecting portion 52 on the pump head 5 is locked in the inner sleeve 3, so that the pump head 5 and the cap 1 are in contact with each other. At this time, the pump head 5 cannot be pressed, which makes it easy to transport. In addition, when in use, after rotating the pump head 5, the pump tube 4 is bounced open under the action of the spring releasing the potential energy, and the lock between the pump head 5 and the inner sleeve 3 is released. After the pump head 5 is pressed, the liquid in the bottle passes through the pump chamber 2, the pump tube 4 and the pump head 5 in turn, and is finally pressed out from the liquid outlet 50. After the pump head 5 is released, the spring automatically bounces the pump tube 4 and the pump head 5 back to their original positions, which is convenient to use.

[0033] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
