Description

TECHNICAL FIELD

[0001] The present application relates to the field of evaporation equipment, in particular to a self-cleaning nozzle. BACKGROUND

[0002] In the evaporation system, the corresponding liquid needs to be sprayed onto the evaporation mesh cloth through the nozzle, so that the water in the liquid is quickly evaporated on the evaporation mesh cloth, and the corresponding required crystal is formed. Because the liquid contains a large amount of various elements, it will cause the nozzle to crystallize after being used for a certain period of time, thereby causing the nozzle to be blocked. SUMMARY

[0003] Therefore, the present application provides a self-cleaning nozzle which can be self-cleaned to reduce the occurrence of nozzle blockage.

[0004] In order to achieve the above-mentioned purpose, the present application realizes the following technical scheme:

[0005] A self-cleaning nozzle, characterized in that: comprising a nozzle body, a telescopic rod and an elastic diaphragm, a water containing cavity is arranged in the nozzle body, a water inlet, a water outlet and a mounting hole which are communicated with the water containing cavity are arranged on the nozzle body; the elastic diaphragm is fixedly installed on the mounting hole and closes the mounting hole, one end of the telescopic rod is fixedly arranged with the elastic diaphragm and the other end of the telescopic rod is provided with a blocking part, the blocking part extends into the water outlet and closes the water outlet; when the water inlet is water, the water pressure of the water containing cavity rises, the elastic diaphragm expands from inside to outside and drives the blocking part of the telescopic rod to retract, thereby opening the water outlet.

[0006] The self-cleaning nozzle of the present application can realize self-cleaning function by arranging the telescopic rod in the nozzle body. Since the telescopic rod is fixedly connected to the elastic diaphragm, when the water inlet is water, the water pressure in the water containing cavity rises, the elastic diaphragm expands from inside to outside and drives the blocking part of the telescopic rod to retract, thereby opening the water outlet for water spraying. When there is no water pressure, the telescopic rod resets and extends out to close the water outlet through the blocking part. Since the telescopic rod can move in and out, it can rub the water outlet, thereby cleaning the water outlet.

[0007] In some embodiments, the water outlet is a tapered hole with a large inner diameter and a small outer diameter, and the blocking part is a tapered part matched with the tapered hole. Preferably, the taper of the tapered hole and the tapered part are the same, and in order to increase the sealing performance, the tapered part can be made of a material with a certain elasticity or a sealing ring can be added outside. Preferably, the tapered part is integrally formed with the telescopic rod. The telescopic rod and the elastic diaphragm can be fixedly connected by screws, glue or a latch.

[0008] In some embodiments, the water outlet is located at the lower end of the nozzle body, and the mounting hole is located above the water outlet.

[0009] In some embodiments, the movable end of the telescopic rod extends out of the water outlet of the spray head body, and a blocking piece is fixedly arranged at the end of the movable end. The blocking piece is arranged to allow the water to be sprayed around after being discharged from the water outlet, thereby increasing the spraying area. The blocking piece and the telescopic rod can be an integral structure or connected by disassembly and assembly.

[0010] In some embodiments, the telescopic rod is provided with a shaking pattern. Since the telescopic rod is connected to the elastic diaphragm at one end and provided with the shaking pattern, when the water flow impacts, the telescopic rod moves around, thereby increasing the collision frequency of the blocking part and the water outlet, which can further improve the self-cleaning effect.

[0011] In an embodiment, the shaking pattern is a spiral pattern. The shaking pattern can also be tooth-shaped, spaced annular, or other irregular shapes.

[0012] In some embodiments, the water inlet is arranged in the middle of the spray head body, and the axis of the water inlet is arranged to be perpendicular to the axis of the telescopic rod. The water inlet is arranged to be offset from the axis of the telescopic rod, so that the telescopic rod is not uniformly impacted by the water flow, and the shaking frequency of the telescopic rod is higher.

[0013] In some embodiments, the elastic diaphragm is a rubber sheet. It can also be other elastic materials such as silica gel, spring steel, polyurethane elastomer, etc.

[0014] In some embodiments, the elastic diaphragm is fixedly connected to the spray head body by a first screw, and a pressing plate is further arranged on the elastic diaphragm.

[0015] From the above technical solutions, the present application has at least the following advantages and positive effects:

[0016] The self-cleaning spray head of the present application is provided with a telescopic rod in the spray head body. Since the telescopic rod is fixedly connected to the elastic diaphragm, when the water inlet is filled with water, the water pressure in the water-containing cavity rises, the elastic diaphragm expands from inside to outside and drives the blocking part of the telescopic rod to retract, thereby opening the water outlet for water spraying. When there is no water pressure, the telescopic rod is reset to extend through the blocking part to close the water outlet. Since the telescopic rod extends and retracts, it can rub against the water outlet, thereby cleaning the water outlet and achieving the function of self-cleaning. BRIEF DESCRIPTION OF DRAWINGS

[0023] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings. The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0024] Referring to Figures 1 to 5 , the present embodiment provides a self-cleaning spray head, which comprises a spray head body 1, a telescopic rod 2 and an elastic diaphragm 3. The spray head body 1 is provided with a water containing cavity 11. The spray head body 1 is provided with a water inlet 12, a water outlet 13 and a mounting port 14 which are communicated with the water containing cavity 11. The elastic diaphragm 3 is fixedly installed on the mounting port 14 and closes the mounting port 14. One end of the telescopic rod 2 is fixedly provided with the elastic diaphragm 3, and the other end of the telescopic rod 2 is provided with a plugging part 21. The plugging part 21 extends into the water outlet 13 and closes the water outlet 13. When water is filled into the water inlet 12, the water pressure in the water containing cavity 11 rises, the elastic diaphragm 3 expands from inside to outside and drives the plugging part 21 of the telescopic rod 2 to retract, thereby opening the water outlet 13.

[0025] The self-cleaning spray head is provided with the telescopic rod 2 in the spray head body 1. Since the telescopic rod 2 is fixedly connected to the elastic diaphragm 3, when water is filled into the water inlet 12, the water pressure in the water containing cavity 11 rises, the elastic diaphragm 3 expands from inside to outside and drives the plugging part 21 of the telescopic rod 2 to retract, thereby opening the water outlet 13 for water spraying. When there is no water pressure, the telescopic rod 2 resets and extends out to close the water outlet 13 through the plugging part 21. Since the telescopic rod 2 performs telescopic movement, it can rub against the water outlet 13, thereby cleaning the water outlet 13 and realizing the self-cleaning function.

[0026] The water outlet 13 is a tapered hole with a large inner diameter and a small outer diameter, and the plugging part 21 is a tapered part matched with the tapered hole. Preferably, the taper of the tapered hole and the tapered part are the same. In order to increase the sealing performance, the tapered part can be made of a material with a certain elasticity or a sealing ring can be added outside. Preferably, the tapered part is integrally formed with the telescopic rod 2. The telescopic rod 2 and the elastic diaphragm 3 can be fixedly connected by screws, glue or a latch.

[0027] The water outlet 13 is located at the lower end of the spray head body 1, and the mounting hole 14 is located above the water outlet 13.

[0028] The movable end of the telescopic rod 2 extends out of the spray head body 1 from the water outlet 13, and a blocking piece 4 is fixedly arranged at the terminal end of the movable end. The blocking piece 4 is arranged to allow the water to be sprayed around after coming out of the water outlet 13, thereby increasing the spraying area. The blocking piece 4 and the telescopic rod 2 can be an integral structure or connected through disassembly and assembly.

[0029] The telescopic rod 2 is provided with a shaking line. Due to the arrangement of the shaking line and the connection of one end of the telescopic rod 2 to the elastic diaphragm 3, the telescopic rod 2 moves around when the water flow impacts, thereby increasing the collision frequency of the blocking part 21 and the water outlet 13, which can further improve the self-cleaning effect.

[0030] The shaking line is a spiral line 22. The shaking line can also be tooth-shaped, spaced annular, or other irregular shapes.

[0031] The water inlet 12 is arranged in the middle of the spray head body 1, and the axis of the water inlet 12 is arranged in a non-planar perpendicular manner with the axis of the telescopic rod 2. The water inlet 12 is arranged offset from the axis of the telescopic rod 2, so that the telescopic rod 2 is not uniformly impacted by the water flow, and the shaking frequency of the telescopic rod 2 is higher.

[0032] The elastic diaphragm 3 is a rubber sheet. It can also be other elastic materials such as silica gel, spring steel, polyurethane elastomer, etc.

[0033] The elastic diaphragm 3 is fixedly connected to the spray head body 1 by the first screw 6, and the elastic diaphragm 3 is further provided with a pressing plate 5.

[0034] The working process and use method of the self-cleaning spray head of the above embodiment are briefly described as follows:

[0035] Referring to Figure 5 When water enters the water inlet 12, the water pressure in the water storage cavity 11 rises, the elastic diaphragm 3 expands from the inside to the outside and drives the blocking part 21 of the telescopic rod 2 to retract, thereby opening the water outlet 13 to spray water. Referring to Figure 4 When there is no water pressure, the telescopic rod 2 is reset to extend through the blocking part 21 to close the water outlet 13. Due to the telescopic movement of the telescopic rod 2, the water outlet 13 can be rubbed, thereby cleaning the water outlet 13, thereby realizing the self-cleaning function. Moreover, the water flow will impact the spiral line of the telescopic rod when the water inlet is in water, which can increase the shaking frequency of the telescopic rod, thereby increasing the collision frequency, and further improving the cleaning effect.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the above embodiments of the present application are described in detail, those skilled in the art should understand that the technical solutions recorded in the above embodiments can be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments.
