Description

Technical Field

[0001] The utility model relates to the technical field of humidifier spray pipes, in particular to a spray pipe device with a changeable nozzle. Background Art

[0002] A hot dry steam humidifier is a special type of humidifier that humidifies indoor air by generating dry hot steam through heating. This humidifier combines the two processes of heating and evaporation to effectively increase indoor humidity and improve air quality. Its working principle is relatively straightforward: first, the water inside the humidifier is heated to boiling to produce steam. Subsequently, it passes through a steam-water separation device to ensure that only dry steam is released into the room. This device can effectively prevent condensed water from entering the air conditioning system and ensure the purity of the steam.

[0003] Hot dry steam humidifier has many significant advantages. First, because it uses an external steam source, no other energy loss is required during the heating process, so it is highly economical. It is synchronized with the air conditioning system, beautiful and durable. Furthermore, the hot dry steam humidifier adopts isothermal humidification, with high humidification efficiency and stable and reliable operation. In addition, a variety of control methods enable this humidifier to adapt to different working environments and achieve high-precision control.

[0004] The steam nozzle serves as an output device of the hot dry steam humidifier, which mainly includes a nozzle with a cavity, and a plurality of nozzles are arranged on the nozzle to spray the dry steam in the cavity outward, thereby achieving the purpose of humidifying the dry air.

[0005] However, since the nozzles on the nozzles are pre-set before leaving the factory, if there are foreign objects in the dry steam in the cavity during use, the nozzles are easily blocked, and the existing solution is to directly replace the nozzles. In addition, the nozzles on the current nozzles have a single specification, and when facing different humidification environments, different requirements are often required for the spray volume of dry steam. Since the nozzles cannot be replaced, the spray volume can only be changed by replacing nozzles of different specifications. The above situation has invisibly caused an increase in the cost of use.

[0006] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0007] The purpose of the utility model is to overcome the above-mentioned problems of the prior art and provide a nozzle-changeable nozzle device to solve the technical problems in the prior art that the nozzle is blocked by foreign matter and cannot be repaired in time, and the high cost caused by the fact that the spray volume can only be changed by replacing different nozzles in the face of different humidification environments.

[0010] The hollow cavity is provided with a nozzle module corresponding thereto, the nozzle module is installed into the hollow cavity from the installation port, and is limitedly sealed by an end cover matching the installation port; the end cover is connected to the nozzle body to form a semi-enclosed steam cavity; the nozzle module includes a plurality of nozzle units;

[0011] The nozzle body is provided with a nozzle window which can be communicated with the steam chamber, and any of the nozzle units can spray the dry steam in the steam chamber outward through the nozzle window.

[0012] Furthermore, the hollow cavity includes a first cavity for tightening the end cover, a second cavity for accommodating the nozzle module, and a third cavity for guiding dry steam to enter, and the first cavity, the second cavity and the third cavity are interconnected.

[0013] Furthermore, the inner diameter of the second cavity is smaller than the inner diameter of the first cavity.

[0014] Further, the second cavity is in the shape of a regular hexagonal prism, and correspondingly, the nozzle module is a nozzle sleeve in the shape of a regular hexagonal prism, with the nozzle units arranged on each side.

[0015] Furthermore, the same nozzle unit includes a plurality of nozzles with the same specifications and arranged in a straight line.

[0016] Furthermore, the specifications of the nozzles on each of the nozzle units are the same.

[0017] Furthermore, the specifications of the nozzles on each of the nozzle units are different.

[0018] Furthermore, the nozzle specifications of each nozzle unit are partially the same.

[0019] Furthermore, the end cover, the nozzle sleeve, and the nozzle body are all made of stainless steel.

[0034] The utility model is further described in detail below based on the accompanying drawings and embodiments. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figure 1 to Figure 4 As shown, the present solution provides a nozzle-changeable nozzle device, comprising a nozzle body 1 with a hollow cavity 101, one end of the nozzle body 1 serving as a dry steam input port 105, and the other end serving as a mounting port 106, wherein the dry steam input port 105, the hollow cavity 101 and the mounting port 106 are interconnected;

[0036] The hollow cavity 101 is provided with a nozzle module 2 corresponding thereto. The nozzle module 2 is installed into the hollow cavity 101 from the installation port 106 and is limitedly sealed by an end cover 3 matching the installation port 106. The end cover 3 is connected to the nozzle body 1 to form a semi-enclosed steam cavity 107. The nozzle module 2 includes a plurality of nozzle units 201.

[0037] The nozzle body 1 is provided with a nozzle window 108 that can communicate with the steam chamber 107 , and any of the nozzle units 201 can spray the dry steam in the steam chamber 107 outward through the nozzle window 108 .

[0038] Working principle:

[0039] The device forms a steam chamber 107 for accommodating the nozzle module 2 through an end cover 3 and a nozzle body 1 that can be screwed together. Dry steam is input into the steam chamber 107 through a dry steam input port 105.

[0040] The required nozzle unit 201 is changed by changing the positions of the nozzle unit 201 and the nozzle window 108 on the nozzle module 2;

[0041] The dry steam in the steam chamber 107 is continuously outputted by the external supply pressure, and the dry steam is sprayed outward through the nozzle unit 201 corresponding to the nozzle window 108, thereby achieving the purpose of humidifying the external air.

[0042] It should be noted that, in order to ensure that the end cover 3 can be conveniently connected to the nozzle body 1, a gear ring 301 is further provided on the end cover 3 in this embodiment for facilitating manual screw connection.

[0043] It should be noted that, in this embodiment, the end cover 3, the nozzle sleeve 203, and the nozzle body 1 are all made of stainless steel, which has excellent high pressure resistance and corrosion resistance and can extend the service life.

[0044] like Figure 5 and Figure 6 As shown, the hollow cavity 101 includes a first cavity 102 for tightening the end cover 3, a second cavity 103 for accommodating the nozzle module 2, and a third cavity 104 for guiding dry steam to enter, and the first cavity 102, the second cavity 103 and the third cavity 104 are interconnected.

[0045] The inner diameter of the second cavity 103 is smaller than the inner diameter of the first cavity 102. This structure can ensure that the nozzle module 2 will not extend from the dry steam input port 105 after being installed from the installation port 106, so that it is confined in the first cavity 102;

[0046] The inner diameter of the first cavity 102 is not less than the inner diameter of the second cavity 103 , so that the nozzle module 2 can pass through smoothly.

[0047] like Figure 4 and Figure 7 As shown, as a specific embodiment of the present scheme, the second cavity 103 is in the shape of a regular hexagonal prism, and correspondingly, the nozzle module 2 is a nozzle sleeve 203 in the shape of a regular hexagonal prism, with the nozzle unit 201 arranged on each side; and the first cavity 102 is mainly used to form a connection with the end cover 3, so it adopts a cylindrical shape, and the inner wall is provided with a thread; the third cavity 104 is also cylindrical to facilitate the smooth passage of dry steam.

[0048] It should be noted that in order to ensure that the end cover 3 can well block and limit the corresponding end of the nozzle sleeve 203, the present solution provides a baffle 204 at the end of the nozzle sleeve 203. The baffle 204 is a regular hexagon and can well interfere with the tightened end cover 3.

[0049] The nozzle unit 201 includes a plurality of nozzles 202 of the same specification and arranged in a straight line.

[0050] The nozzle units 201 in this embodiment are of the following three types:

[0051] The first type: the specifications of the nozzles 202 on each of the nozzle units 201 are the same. Since this solution ensures that the specifications of the nozzles 202 on the six nozzle units 201 are the same, it can effectively solve the problem of nozzle blockage affecting work by switching to another nozzle unit 201 with the same nozzle 202 specifications when the nozzle 202 is blocked.

[0052] The second type: the specifications of the nozzles 202 on each nozzle unit 201 are different. Since this solution ensures that the specifications of the nozzles 202 on the six nozzle units 201 are different, the amount or rate of dry steam sprayed by the nozzles 202 on each nozzle unit 201 is different, thereby meeting the rapid switching requirements of different scenarios.

[0053] The third type: the specifications of the nozzles 202 on each nozzle unit 201 are partially the same. This solution can simultaneously meet the above-mentioned problem of nozzle blockage affecting work by switching to another nozzle unit 201 with the same nozzle specifications when the nozzle 202 is blocked, and meet the usage requirements of different scenarios by switching nozzle units 201 with different nozzle specifications.

[0054] As an optimization of the device, a corresponding nozzle window frame 4 is provided on the inner wall of the nozzle window 108 . The nozzle window frame 4 is made of rubber material, which can increase the air tightness between the nozzle window 4 and the corresponding nozzle unit 201 .

[0055] The above description is only for illustrating the implementation mode of the present invention and is not intended to limit the present invention. For those skilled in the art, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
