Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a novel pressure-boosting nozzle structure and a range hood. Background Technology

[0002] The cleaning of range hoods is based on water. Water in a cup is drawn into the pump under vacuum, then pressurized by the pump before entering the nozzles. Finally, the water is sprayed onto the impeller of the range hood through the nozzle holes to clean it.

[0003] In the existing technology, most water pumps used for cleaning range hoods are limited by space and cost, and are generally miniature water pumps. This results in insufficient output pressure, and the water pressure does not change much after passing through the nozzle, which is not good enough for the primary cleaning effect on the impeller. Summary of the Invention

[0004] This utility model aims to solve, at least to some extent, one of the problems existing in the prior art. To this end, this utility model proposes a novel pressure-boosting nozzle structure, which is simple in structure. By adding a spiral baffle inside the nozzle body, the water flow is gradually formed into a vortex, thereby achieving the effect of converging and pressurizing the vortex, and thus effectively improving the ejection pressure of the water flow.

[0005] In addition, this utility model also proposes a range hood with a reasonable design that can effectively improve the cleaning effect of the range hood and further reduce the production cost of the product.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of the claimed invention.

[0028] Example:

[0029] like Figure 1-3As shown, a novel pressurizing nozzle structure includes a nozzle body 1, a spiral baffle 2, and a water outlet diaphragm 5. A hollow water flow channel 3 is defined within the nozzle body 1. An inlet 31 and an outlet 32, which are connected to the water flow channel 3, are respectively provided at both ends of the nozzle body 1. The spiral baffle 2 is fixedly installed on the inner side wall of the water flow channel 3, and the spiral baffle 2 causes the water flowing into the nozzle body 1 through the inlet 31 to spiral towards the outlet 32. The water outlet diaphragm 5 is detachably installed at the outlet 32, and a spray nozzle 51, which is connected to the outlet 32, is provided on the water outlet diaphragm 5.

[0030] The pressurizing nozzle structure in this embodiment is simple in structure. By adding a spiral baffle 2 inside the nozzle body 1, the water flow gradually forms a vortex, thereby achieving the effect of converging and pressurizing the vortex, which can effectively improve the ejection pressure of the water flow.

[0031] In this embodiment, a hollow water flow channel 3 is defined within the nozzle body 1. An inlet 31 connected to the water flow channel 3 is provided at one end of the nozzle body 1, allowing external water supply to enter the water flow channel 3 through the inlet 31. An outlet 32 ​​connected to the water flow channel 3 is provided at the other end of the nozzle body 1, allowing the water flowing into the water flow channel 3 to be output outward through the outlet 32. In addition, a spiral baffle 2 is added to the inner wall of the water flow channel 3. After the external water supply enters the nozzle body 1 through the inlet 31, the water flow continues to flow from the inlet 31 towards the outlet 32. The spiral baffle 2 guides the water flow as it passes through the water flow channel 3. The spiral baffle 2 guides and blocks the water flow in the outer area, causing the water flow to gradually form a vortex, thereby causing the water flow to spiral and achieve a flow concentration and pressurization effect. Then, the concentrated and pressurized water flow continues to be sprayed outward through the outlet 32, thus increasing the spray pressure of the water flow.

[0032] Furthermore, the nozzle body 1 has a vertical section 11 and a horizontal section 12. The vertical section 11 and the horizontal section 12 are connected to form an L-shaped structure. The water inlet 31 is located at the upper end of the vertical section 11, and the water outlet 32 ​​is located at the end of the horizontal section 12 away from the vertical section 11. The spiral baffle 2 is disposed inside the vertical section 11.

[0033] In this embodiment, the vertical section 11 and the horizontal section 12 are connected to form an L-shaped structure for the nozzle body 1. Specifically, the inlet 31 is located at the upper end of the vertical section 11, the lower end of the vertical section 11 is connected to the horizontal section 12, and the horizontal section 12 has an outlet 32 ​​at the end away from the vertical section 11. The spiral baffle 2 is disposed inside the vertical section 11. The spiral baffle 2 causes the water flow entering the water flow channel 3 through the inlet 31 to spiral and achieve a flow concentration and pressurization effect. Then, the water flow after flow concentration and pressurization continues to be sprayed out through the outlet 32, thus increasing the spray pressure of the water flow. More preferably, the length of the vertical section 11 is greater than the length of the horizontal section 12, which can effectively improve the flow concentration and pressurization effect of the spiral baffle 2.

[0034] In this embodiment, the spiral baffle 2 extends spirally from the inlet 31 to the outlet 32 ​​within the vertical section 11, thus forming a spiral structure. Since the outer wall of the spiral baffle 2 is connected to the inner wall of the water flow channel 3, and a flow channel is formed between the inner walls of the spiral baffle 2, the spiral baffle 2 and the water flow channel 3 are coaxially arranged. When external water enters the water flow channel 3 through the inlet 31, the spiral baffle 2 guides the flow of water, which is similar to the "rifle principle". Specifically, the spiral baffle 2 guides and blocks the water flow in the outer area, causing the water flow to gradually form a vortex. The vortex can achieve the effect of converging and pressurizing. The water flow after converging and pressurizing is then ejected at high pressure from the outlet 32, thus increasing the ejection pressure of the water flow and greatly improving the cleaning effect of the nozzle.

[0035] Preferably, it also includes a water inlet connector 4, which is detachably disposed at the water inlet 31, and has a water inlet interface 41 that communicates with the water inlet 31.

[0036] Specifically, the water inlet connector 4 has an internal thread on its inner circumferential wall near the water inlet 31, and the nozzle body 1 has an external thread at the end near the water inlet 31, so that the water inlet connector 4 and the nozzle body 1 are threaded together.

[0037] In this embodiment, since the water inlet connector 4 has an internal thread on the inner peripheral wall at the end away from the water inlet interface 41, and the nozzle body 1 has an external thread at the end close to the water inlet 31, the water inlet connector 4 and the nozzle body 1 are threaded together, so that the water inlet connector 4 is detachably set at the water inlet 31. At the same time, the water inlet interface 41 connected to the water inlet 31 is provided on the water inlet connector 4, so that the external water supply enters the water flow channel 3 after passing through the water inlet interface 41 and the water inlet 31 in sequence.

[0038] Furthermore, it also includes a mounting cover 6, through which the water outlet diaphragm 5 is mounted together with the nozzle body 1.

[0039] Preferably, a limiting part 33 is provided at the edge of the water outlet 32, and a positioning part is provided at the end of the water outlet 5 away from the water nozzle 51. The positioning part and the limiting part 33 are connected to each other to limit the displacement of the water outlet 5.

[0040] Specifically, the water outlet membrane 5 has a recessed groove at one end near the water outlet 32 ​​to form a positioning part, and a protrusion is provided at the lower end of the outer edge of the water outlet 32 ​​to form a limiting part 33. The protrusion extends into the groove so that the positioning part and the limiting part 33 are connected together.

[0041] Preferably, a water inlet 61 is provided at one end of the mounting cover 6, and an opening is provided at the other end of the mounting cover 6. The water outlet membrane 5 abuts against the edge of the water inlet 61, and the water outlet 32 ​​passes through the opening and connects with the water outlet membrane 5.

[0042] Specifically, the mounting cover 6 has an internal thread on its inner circumferential wall near the open end, and the nozzle body 1 has an external thread at the end near the outlet 32, so that the mounting cover 6 and the nozzle body 1 are threaded together.

[0043] In this embodiment, a protrusion is provided at the edge of the outlet 32 ​​to form a limiting part 33, and a groove is provided on the water outlet diaphragm 5 to form a positioning part. The protrusion extends into the groove so that the positioning part and the limiting part 33 are connected together. Thus, the displacement of the water outlet diaphragm 5 is limited by the connection between the positioning part and the limiting part 3334, thereby detachably setting the water outlet diaphragm 5 at the outlet 32. At the same time, it can also help improve the assembly efficiency between the water outlet diaphragm 5 and the outlet 32. In addition, a spray nozzle 51 connected to the outlet 32 ​​is provided on the water outlet diaphragm 5, so that the pressurized water continues to pass through the outlet 32 ​​and the spray nozzle 51 in sequence before being sprayed outward. More preferably, a water inlet 61 is provided at one end of the mounting cover 6, and an opening is provided at the other end of the mounting cover 6. The mounting cover 6 has an internal thread on its inner peripheral wall at the end away from the water inlet 61, and the nozzle body 1 has an external thread at the end near the water outlet 32. When the water outlet diaphragm 5 is installed at the water outlet 32, the mounting cover 6 has a flange protruding at the edge of the water inlet 61 so that the water outlet end of the water outlet 5 abuts against the flange of the water inlet 61 of the mounting cover 6. In this way, the water outlet 51 is correspondingly set with the water inlet 61 of the mounting cover 6. Then, the water outlet diaphragm 5 installed at the water outlet 32 ​​of the nozzle body 1 passes through the opening and is connected to the water outlet diaphragm 5. The mounting cover 6 is threadedly connected to the nozzle body 1, so that the water outlet diaphragm 5 is installed together with the nozzle body 1 through the mounting cover 6.

[0044] In this embodiment, the pressurized nozzle structure is preferably applied to a range hood. Specifically, the range hood includes a range hood body and a pressurized nozzle structure as described above. A water pump connected to an external water supply is provided on the range hood body. The nozzle body 1 is located inside the range hood body. More preferably, the water outlet 32 ​​of the nozzle body 1 is correspondingly arranged with the fan of the range hood body so that the water flow sprayed out through the water outlet 32 ​​can flush the fan. Since the water pump's outlet is connected to the inlet connector 4, the water pump's outlet can be connected to the inlet 31 via the inlet interface 41. The pump's operation then delivers external water through the inlet interface 41 and inlet 31 into the water flow channel 3. The water flow in the channel 3 continues towards the outlet 32. The spiral baffle 2 guides and blocks the water flow in the outer area, gradually forming a vortex. This vortex achieves a converging and pressurizing effect, thus pressurizing the water flow. The pressurized water then continues to be sprayed out at high pressure through the outlet 32. This allows the sprayed water to clean the range hood and / or fan. Its reasonable design effectively improves the cleaning effect of the range hood and further reduces production costs.

[0045] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
