Description

Technical Field

[0001] The utility model relates to the technical field of automobile windshield wiper water spray nozzles, in particular to a novel automobile glass water spray nozzle. Background Art

[0002] When the car wiper is cleaning the glass, the water nozzle installed on the hood sprays water on the glass, and then the wiper wipes back and forth to clean the glass. However, the water flow from most water nozzles is cylindrical. After spraying on the glass, it cannot be evenly spread on the glass at the first time, resulting in incomplete cleaning. It may even take two or three times of water spraying to complete the cleaning of the glass, and the amount of water used is also very large.

[0003] Therefore, some companies have developed water nozzles that can spray fan-shaped water flows, which are generally divided into two types. One is a copper spherical nozzle, which sprays water in a spiral shape. This copper nozzle is more expensive; the other is an imported water nozzle, the main body of which is made of plastic. The main structure is a water inlet, a thrust valve, a water nozzle shell, and an inner core. The water nozzle shell and the inner core form a sealed chamber. After the water flows into the water through the water inlet, it passes through several cylinders at the inner core to evenly disperse the water flow. The uniform water flows out from both sides of the crescent-shaped barrier to form a pressurized effect. The pressurized water flows out from the outlet in a fan shape.

[0004] With regard to imported water nozzles, the current problem is that the sealing requirements for the overall structure are very high. The inner core and the outer shell must be completely sealed to form a fan-shaped water flow. If there is a small gap between the inner core and the outer shell, or the thickness of the inner core is lower than the thickness of the outer shell cavity, so that the water flows out from above the crescent-shaped barrier piece on the inner core, then the sprayed water flow is also cylindrical, which requires high overall processing accuracy and correspondingly higher production costs. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to design a new automobile glass water spray nozzle which has low processing cost, low precision requirement and can spray fan-shaped water flow.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a novel automobile glass water spray nozzle, comprising a shell, an inner core installed in the front cavity of the shell, and a fixed water inlet connected to the lower part of the shell through a thrust valve. Water flows into the shell from the water inlet and the thrust valve, and sprays out a fan-shaped water flow through the sealed channel of the shell and the inner core.

[0007] Furthermore, the inner core is a sheet plastic product, the back side is a smooth plane, and the front side has a concave water flow channel, the water flow channel is composed of a water inlet, a special-shaped spoiler, and a water outlet, and a triangular baffle is provided at the water outlet. After the water flows in from the water inlet, it passes through the special-shaped spoiler to make the water flow uniform, and then the water flows hit the triangular baffle, and a uniform fan-shaped water flow is sprayed out from the water outlet.

[0008] Furthermore, the upper plane of the triangular baffle plate is lower than the upper plane of the inner core, that is, water can be sprayed from above and both sides of the triangular baffle plate. If the upper plane of the triangular baffle plate is flush with the upper plane of the inner core, the sprayed water is a linear water column.

[0009] Furthermore, when there is a small gap between the upper surface of the inner core and the cavity of the outer shell, it does not affect the final fan-shaped water flow spraying effect.

[0010] Furthermore, the inner core can be installed in both positive and negative directions to adjust the water jet height. That is, when the inner core is installed in the positive direction and the concave water flow channel faces downward, the water jet position is lower; when the inner core is installed in the reverse direction and the concave water flow channel faces upward, the water jet position is higher.

[0011] Furthermore, the shell is fixed to the vehicle body by a clamping manner, and a gasket is installed between the thrust valve and the shell, and the gasket plays a buffering and shock-absorbing role when the shell and the vehicle body are fixed.

[0012] Furthermore, the thrust valve is a one-way valve, which prevents water leakage when the water outlet is not working.

[0013] Beneficial Effects

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model reduces the sealing requirement between the inner core and the outer shell through the unique inner core structure design, and when there is a small gap between the upper surface of the inner core and the cavity of the outer shell, the final fan-shaped water flow spraying effect is not affected.

[0016] The inner core designed by the utility model can be installed forwards and backwards, and the height of the water flow spraying can be changed by changing the direction and position of the water inlet hole and the water flow channel, so as to adapt to different use requirements in turn.

[0020] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example 1

[0022] The novel automobile glass water spray nozzle comprises a shell 2, an inner core 1 is installed in the front cavity of the shell 2, and a fixed water inlet 5 is connected directly below the shell 2 through a thrust valve 4.

[0023] The housing 2 is fixed to the vehicle body by means of a clamping connection, and a gasket 3 is installed between the thrust valve 4 and the housing 2 , and the gasket 3 plays a role of buffering and shock absorption when the housing 2 and the vehicle body are fixed.

[0024] One side of the water inlet 5 is connected to the water pipe, and the other side is connected to the thrust valve 4, and is connected to the housing 2 through the thrust valve 4. The thrust valve 4 is a one-way valve, which plays a role in preventing the water outlet 9 from leaking when it is not working.

[0025] The inner core 1 is installed in the cavity at the water outlet of the outer shell 2 by mechanical pressing, and the inner core 1 and the outer shell 2 together form a sealed channel.

[0026] The inner core 1 is a sheet plastic product, the back side is a smooth plane, and the front side has a concave water flow channel 6, which is composed of a water inlet 7, a special-shaped spoiler 8 and a water outlet 9. A triangular baffle 10 is provided in the middle of the water outlet 9. The water flows in from the water inlet 7, passes through the special-shaped spoiler 8 to make the water flow uniform, and then hits the triangular baffle 10 to spray out a fan-shaped water flow from the water outlet 9.

[0027] Particularly, the upper plane of the triangular baffle plate 10 is lower than the upper plane of the inner core 1 , that is, the water flows through the upper side and both sides of the triangular baffle plate 10 .

[0028] In particular, a sealed chamber is formed between the inner core 1 and the outer shell 2 for water to flow through, but it is not required to be completely sealed, that is, there can be a small gap between the upper surface of the inner core 1 and the cavity of the outer shell 2, which does not affect the final fan-shaped water flow spraying effect.

[0029] In particular, the inner core 1 can be installed in both positive and negative directions to adjust the water jet height. That is, when the inner core 1 is installed in the positive direction and the concave water flow channel 6 faces downward, the water jet position is lower; when the inner core 1 is installed in the negative direction and the concave water flow channel 6 faces upward, the water jet position is higher.

[0030] When in use: the water nozzle is installed on the vehicle body, the water inlet 5 is connected to the water pipe, the water flows through the water inlet 5 and the thrust valve 4 into the water flow channel 6 in the outer shell 2, and after the water flows through the water inlet hole 7, the water flow is uniform under the action of the special-shaped spoiler 8, and after hitting the triangular baffle plate 10, a fan-shaped water flow is sprayed out from the water outlet 9.
