Description

A push-type water dispenser Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a press-type water dispenser. Background Art

[0002] Currently, there are numerous devices on the market that work with bottled drinking water, such as water dispensers and hand-operated water pumps. Hand-operated water pumps are highly popular because they can quickly increase the internal pressure of a dispenser while maintaining it for a long time. They are also easy to clean, portable, convenient to use, and inexpensive. However, most dispensers with manual pumps have the pump mounted directly on the dispenser's cover. This can cause excessive shaking as the pump moves up and down when the pump is pressed to increase pressure. After a certain period of use, the connection between the cover and the pump can become loose, and even the connection between the cover and the dispenser body can become damaged, leading to problems such as loosening or breakage, significantly shortening the dispenser's service life.

[0003] It can be seen that the existing technology still needs to be improved and enhanced.

[0024] The present invention provides a press-type water dispenser. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0025] In the description of this utility model, it should be understood that the terms "upper, lower, left, and right" and the like indicating directions or positions are based on the directions or positions shown in the accompanying drawings and are intended solely to facilitate and simplify the description of this utility model and are not to be construed as limiting the scope of this utility model. Furthermore, the terms "installation" and "connection" are to be understood broadly, and those skilled in the art will be able to understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0026] Referring to Figures 1 to 4 , the present invention provides a push-type water dispenser, comprising a main body 1 and a cover 2 disposed at an opening of the main body 1 , a presser, and a sink 3 . The sink 3 is located at the center of the cover 2 . The presser comprises a pressing head 4 , a cylinder 5 , a piston 6 , a reset member 7 , and a one-way valve . The pressing head 4 is movable within the sink 3 , with the reset member 7 disposed between the pressing head 4 and the sink 3 . The piston 6 is connected to the distal end of the pressing head 4 and is movably disposed within the cylinder 5 . The one-way valve is disposed at the bottom end of the cylinder 5 . It is understood that the pressing head 4 drives the piston 6 to reciprocate within the cylinder 5 , rapidly forcing air outside the push-type water dispenser into the interior of the dispenser, thereby increasing the air pressure within the main body 1 and primarily discharging drinking water from the main body 1 .

[0027] In this embodiment, the presser has a spring-preloaded locking device, which can fix the presser during transportation and also enhance the overall structural strength of the press-type water dispenser.

[0028] Please refer to Figure 3, which also includes a boss portion 8, an external thread portion 9, a connecting ring 10 and an internal thread portion. The boss portion 8 is arranged on the outer wall of the cylinder 5 near the top of the cylinder 5, and the external thread portion 9 is located above the boss portion 8 and is opened on the outer wall of the cylinder 5. The connecting ring 10 is provided with an internal thread portion that matches the external thread portion 9. The cover body 2 is clamped between the boss portion 8 and the connecting ring 10. The connecting ring 10 cooperates with the external thread portion 9 on the cylinder 5 through the internal thread portion to tightly fix the boss portion 8 on the cover body 2, thereby forming a dense sealing structure and improving the boosting efficiency of the presser.

[0029] In this embodiment, it also includes a water outlet pipe 11, a water outlet seat 12 and a water outlet valve 13. The water outlet seat 12 is embedded in the main body 1, and the water outlet valve 13 is provided on the outside of the water outlet seat 12. The water outlet pipe 11 is provided on the inner side of the water outlet seat 12, and the water inlet of the water outlet pipe 11 is arranged near the bottom end of the main body 1; it can be understood that the water inlet arranged near the bottom end of the main body 1 is convenient for absorbing drinking water at a lower water level, has a greater pressure under the same air pressure, and the water outlet is smoother; in more detail, it also includes a filter element, and the filter element is arranged in the water outlet seat 12. When the air pressure of the main body 1 is increased, the speed of drinking water flowing through the filter element can be accelerated, thereby overcoming the disadvantage of poor water flow at the filter element. In detail, the water outlet seat 12 is connected to the main body 1 by the water outlet pipe 11. The water outlet pipe 11 allows drinking water to flow from the larger main body 1 to the smaller water outlet seat 12, and then pass through the filter element and flow out from the smaller water outlet seat 12. That is, the water outlet seat 12 in this embodiment can be regarded as a filter chamber.

[0030] Specifically, the cover 2 is also provided with a pressure relief valve 14, which is snap-fitted to the cover 2. It also includes a handle 15, which is provided on the outer wall of the main body 1. The connection between the sink 3 and the cover 2 is a smooth transition. The pressure relief valve 14 snaps onto the cover 2, making installation and removal of the pressure relief valve 14 relatively simple. In this embodiment, two handles 15 are symmetrically provided on the side walls of the main body. Users can use the handles 15 on the outer wall of the main body 1 to extract the water dispenser, making it convenient for daily use.

[0031] The push-type water dispenser in this embodiment increases the air pressure in the main body 1 through a presser, so that the drinking water in the main body 1 passes through the water outlet valve 13 under the action of air pressure and gravity. After multiple pressurizations by the pressing head, the drinking water in the push-type water dispenser is ensured to be efficiently discharged from the water outlet valve 1. More importantly, the increase in air pressure in the main body accelerates the speed at which the drinking water flows through the filter element, ensuring that the drinking water flows smoothly through the water outlet seat 12 and the water outlet valve 13, thereby ensuring the water outlet from the water outlet valve 13.

[0032] In summary, the present invention's push-type water dispenser, with its sink 3 disposed on the cover 2, can consistently limit the movement of the push head 4 during its lifting and lowering process, ensuring that the push head 4 remains straight up and down on the cover 2, reducing the shaking of the press during the pressing process. This reduces malfunctions of the push-type water dispenser caused by repeated pressing, extends the dispenser's service life, and enables the press to continuously increase the air pressure within the main body, thereby improving the dispenser's water delivery efficiency. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and possesses a high degree of industrial value.

[0033] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
