DETAILED DESCRIPTION

[0025] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0026] See also Figures 1-4 The adjustable press liquid dispenser includes a liquid storage cylinder 5, a piston rod 2 with one end slidingly arranged in the liquid storage cylinder 5, a pressure head 1 connected to the other end of the piston rod 2, and a straw 6 connected to the other end of the liquid storage cylinder 5. A fixed seat 4 is provided on the outside of the liquid storage cylinder 5, and an adjusting nut 3 for adjusting the stroke of the piston rod 2 is provided between the fixed seat 4 and the pressure head 1. The inner side of the adjusting nut 3 is provided with an internal thread 31, and the outer side of one end of the fixed seat 4 is provided with an external thread 41 connected to the adjusting nut 3.

[0027] Furthermore, a groove is provided on the side of the fixing seat 4, and a scale line 42 is provided in the groove for displaying the end position of the adjusting nut 3. It can be understood that when the adjusting nut 3 rotates along the fixing seat 4, the upper and lower positions of the adjusting nut 3 on the fixing seat 4 will also change, and since the groove is provided on the side of the fixing seat 4, it will not affect the adjustment of the adjusting nut 3. At this time, the precise position of the adjusting nut 3 can be shown by the scale line 42.

[0028] In this embodiment, an anti-slip groove 43 is provided on the outer side of the other end of the fixing base 4, and an anti-slip groove 32 is provided on the outer side of the adjusting nut 3. Specifically, the purpose of the anti-slip groove 43 is to facilitate the installation and disassembly of the fixing base 4, and the purpose of the anti-slip groove 32 is to facilitate the adjustment of the adjusting nut 3, making the use of the liquid dispenser more convenient and quick.

[0029] Furthermore, a conical surface 33 is provided on the outer side of one end of the adjusting nut 3 close to the pressure head 1. Through the design of the conical surface 33, when the pressure head 1 is pressed with one hand by the thumb, the index finger and the middle finger clamp the piston rod 2. The design of the conical surface 33 reserves more space for the fingers, thereby making the liquid dispenser safer and more reliable to use.

[0030] Furthermore, an internal thread 2 44 is provided on the inner side of the other end of the fixing base 4, and the other end of the fixing base 4 is connected to the bottle body 7 through the internal thread 2 44, and is connected to the bottle body 7 with an external thread through the internal thread 2 44. According to the size of the external thread of the different bottle bodies 7, the inner diameter of the internal thread 2 44 can be adjusted to adapt to different bottle bodies 7, so as to facilitate the reuse of the liquid dispenser.

[0031] The pressure head 1 includes a pressure block 11, a connecting sleeve 12 vertically arranged at the bottom end of the pressure block 11, and a liquid outlet pipe 13 arranged on the side of the pressure block 11. One end of the connecting sleeve 12 is connected to one end of the piston rod 2, and the other end of the connecting sleeve 12 is connected to the liquid outlet pipe 13.

[0032] A gland 8 is detachably provided at one end of the fixing seat 4 close to the connecting sleeve 12 , and the other end of the piston rod 2 passes through the gland 8 and is communicated with the liquid storage cylinder 5 .

[0033] The outer side of the connecting sleeve 12 is provided with an external thread 2 121, and the inner side of the pressure cap 8 is provided with an internal thread 3 81 which is detachably connected to the connecting sleeve 12. The internal thread 3 81 on the pressure cap 8 fixes the connecting sleeve 12 of the pressure head 1 in the initial state. When the pressure head 1 is screwed so that the external thread 2 121 of the connecting sleeve 12 is disengaged from the internal thread 3 81 of the pressure cap 8, the pressure head 1 is separated from the pressure cap 8 and no longer in contact. The top end of the adjusting nut 3 is detachably abutted against the bottom end of the pressure block 11. When the piston rod 2 is in a freely extended state, the adjusting nut 3 is adjusted so that the adjusting nut 3 moves upward to support the pressure block 11, thereby limiting the position of the pressure head 1 and locking the position of the pressure head 1, so as to restrain the piston rod 2 and adjust the stroke of the piston rod 2.

[0034] The specific working process of this utility model:

[0035] First, connect the adjustable push-to-dispenser to the bottle body 7. Specifically, after the bottle body 7 is filled with daily chemical products, hold the anti-slip groove 1 43 of the fixing seat 4, insert the straw 6 into the bottle body 7, and tighten the internal thread 2 44 toward the external thread of the bottle body 7 to complete the installation of the adjustable push-to-dispenser.

[0036] In the initial state of the adjustable press liquid dispenser, the adjusting nut 3 is adjusted to the lowest end of the fixing seat 4, and the external thread 2 121 of the pressure head 1 is screwed into the internal thread 3 81 of the pressure cover 8. When it needs to be used, the pressure head 1 is screwed to separate the external thread 2 121 of the pressure head 1 from the internal thread 3 81 of the pressure cover 8. Under the elastic force of the spring in the liquid storage cylinder 5, the pressure head 1 pops out, and liquid is taken by pressing the pressure head 1.

[0037] It can be understood that if the amount of liquid pumped at one time is too much, the anti-slip groove 32 of the adjusting nut 3 is held and twisted to make the adjusting nut 3 rise along the fixing seat 4, and the position of the adjusting nut 3 is observed through the scale line 42. When the adjusting nut 3 reaches the set position, the pressure head 1 is pressed again, and the bottom end of the pressure head 1 abuts against the end of the adjusting nut 3, so that the stroke of the piston rod 2 becomes shorter, thereby reducing the amount of liquid pumped.

[0038] When you need to carry toiletries equipped with an adjustable press-dispenser when going out, screw the adjusting nut 3 until it contacts and locks the pressure head 1, preventing the pressure head 1 from driving the piston rod 2 to move, thereby preventing the toiletries from being squeezed out, making it safer and more reliable to carry the toiletries.

[0039] The pressing pump head in the prior art is shown in FIG. Figure 4 As shown, the press pump head mainly consists of a storage barrel 905, a piston rod 902, a straw 906, a pressure head 901, a bottle cap 904 and a pressure cap 903 on the bottle cap 904, wherein a spring and two one-way ball valves are provided in the storage barrel 905, and the press pump head is installed on the bottle body through the bottle cap 904. The pressure head 901 is pressed to make the piston rod 902 slide in the storage barrel 905, and under the action of the spring and the one-way ball valve, the liquid in the storage barrel is discharged from the pressure head 901 for use. However, the existing press pump head has the disadvantage that it is difficult to accurately adjust the amount of liquid pumped out at one time.

[0040] Compared with the press pump head in the prior art, the adjustable press liquid dispenser of the present invention can control the stroke of the piston rod 2 when the liquid dispenser is taking liquid by adjusting the adjusting nut 3 on the fixing seat 4. The setting of the scale line 42 makes the adjustment of the adjusting nut 3 more precise, and thus makes the stroke adjustment of the piston rod 2 more precise, thereby achieving the effect of accurately adjusting the amount of liquid taken from bath products.

[0041] The conical surface 33 is provided to increase the space between the pressure head 1 and the adjusting nut 3 , thereby avoiding squeezing of fingers when pressing the pressure head 1 , and the adjustable press liquid dispenser is safe and reliable to use.

[0042] The anti-skid pattern 1 43 makes it easy and quick to disassemble the pressure head 1 , and the anti-skid pattern 2 32 makes it even easier and quicker to adjust the adjusting nut 3 .

[0043] The technical features not described in the present invention can be realized by or by adopting the existing technology, and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
