Description

Technical Field

[0001] The utility model relates to the technical field of hot dry steam humidifiers, in particular to an isolated spray pipe used for hot dry steam humidifiers. 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 Chinese utility model patent with publication number CN215597606U discloses a humidifying device for a bellows channel, which includes a steam nozzle. The structure of the steam nozzle is: a shell with a drain hole and an air inlet hole, a heating pipe coiled in the shell, and a plurality of nozzles arranged on the shell; the heating pipe is a U-shaped structure, which is fastened to the inside of the shell by a metal sheet, one end of the heating pipe is close to the pipe cap, and the other end is welded to the drain hole and the air inlet hole respectively, wherein the input end of the heating pipe is located directly above the nozzle, and the output end is located directly below the nozzle.

[0005] The above solution places the heating pipe in the nozzle cavity, which not only makes the structure complicated and difficult to install, but also occupies the space of the nozzle cavity, resulting in that the dry steam entering the pipe cannot be evenly distributed, thereby affecting its spraying effect; in addition, since the heating pipe is completely in contact with the dry steam, the service life of the heating pipe will be affected as the use time increases. For example, the outer wall of the heating pipe is corroded and falls into the nozzle cavity, which will cause the hidden danger of nozzle clogging.

[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 an isolated nozzle for a hot dry steam humidifier, so as to solve the technical problems that the heating pipe is arranged in the steam nozzle cavity in the prior art, resulting in a complex structure, difficult installation, occupying the nozzle cavity space, and the outer wall of the heating pipe peeling off due to corrosion during long-term use, which easily causes nozzle clogging.

[0008] The above objectives are achieved through the following technical solutions:

[0010] Furthermore, the inner tube closed end of the inner tube is hemispherical, and correspondingly, the outer tube closed end of the outer tube is hemispherical.

[0011] Furthermore, the nozzle seat is rectangular, and the inner side matches the outer side wall of the inner tube.

[0012] Furthermore, the nozzle seat and the inner tube are bonded together by glue.

[0013] Furthermore, the nozzle seat is made of rubber.

[0014] Furthermore, the thickness of the nozzle seat is greater than the thickness of the heating chamber.

[0015] Furthermore, the nozzle is riveted to the nozzle through-hole unit after passing through the nozzle insertion hole unit.

[0016] Further, the nozzle through-hole unit includes a plurality of nozzle through-holes arranged in a straight line, the nozzle insertion hole unit includes a plurality of nozzle insertion holes arranged in a straight line, and the number of the nozzle insertion holes is the same as the number of the nozzle through-holes.

[0017] Furthermore, the inner tube and the outer tube are made of stainless steel.

[0018] Furthermore, the sealing seat is a nut seat with an inner ring.

The device is not only simple in structure, easy to process and assemble, but also has good preheating effect and can effectively prolong the service life of the nozzle.

[0031] 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.

[0032] like Figure 1 to Figure 3As shown, the present solution provides an isolated nozzle for a hot dry steam humidifier, comprising an inner tube 1 with an air inlet port 101, an inner tube cavity 102 communicating with the air inlet port 101 is provided in the inner tube 1, and a nozzle through-hole unit 103 communicating with the inner tube cavity 102 is provided on the outer wall of the inner tube 1;

[0033] The outer side of the nozzle through-hole unit 103 is provided with a nozzle seat 3 corresponding thereto, and the nozzle seat 3 is provided with a nozzle insertion hole unit 301 corresponding to the nozzle through-hole unit 103; the nozzle 4 extends into the inner tube cavity 102 through the nozzle insertion hole unit 301 and the nozzle through-hole unit 103;

[0034] It also includes an outer tube 2 that can be sleeved on the outside of the inner tube 1, and the outer tube 2 includes a plug port 201 and a nozzle seat slot 202 corresponding to the shape of the nozzle seat 3; after the outer tube 2 and the inner tube 1 are sleeved, they are connected through a sealing seat 5 to form a heating chamber 203, and a heat source inlet 204 and a heat source outlet 205 for input and output of the heat source are provided on the outer tube 2.

[0035] Wherein, the inner tube 1 and the outer tube 2 are made of stainless steel, which is resistant to high pressure and corrosion.

[0036] Working principle:

[0037] like Figure 4 and Figure 5 As shown, the inner wall of the air inlet port 101 is provided with threads so as to be connected to the hot dry steam input pipe; since heat loss, specifically a decrease in temperature, occurs when the hot dry steam is transported from the air supply position of the hot dry steam humidifier to the nozzle, the dry steam in the nozzle needs to be preheated before being ejected by the nozzle, that is, the heating chamber 203 provided in the present scheme is preheated in an isolated manner from the inner tube cavity 102, so that the heat source will wrap the inner tube cavity 102, thereby being able to form a good preheating for the dry steam in the inner tube cavity 102, and will not cause any contact interference to the inner tube cavity 102, thereby ensuring the balance of pressure in various parts of the inner tube cavity 102, and then when the dry steam pressure in the inner tube cavity 102 reaches a certain level, it will be freely ejected through the nozzle 4, and what is ejected is hot dry steam.

[0038] like Figure 3 As shown, in this embodiment, the inner tube closed end 105 of the inner tube 1 is hemispherical, and correspondingly, the outer tube closed end 206 of the outer tube 2 is hemispherical; this structure can make it easier to evenly distribute the heat source in the heating chamber 203; that is, the heat source enters the heating chamber 203 through the heat source inlet 204, and in the heating chamber 203, the heat source will gradually fill the heating chamber 203 under the action of pressure, and will be output outward along the heat source outlet 204 along the heat source outer tube under the continuous input of pressure.

[0039] It should be noted that, in this embodiment, the heat source can be hot steam, which forms a heat circulation system through pipelines, thereby continuously circulating heat for the heating chamber 203.

[0040] In order to address the problem of condensed water on the inner wall of the inner tube cavity 102 due to temperature difference, a small hole can be opened on the outer wall of the inner tube 1 corresponding to the position of the heat source outlet 205 to facilitate the condensed water in the inner tube cavity 102 to penetrate into the heating cavity along the small hole and then be carried away by the heat source along the heat source outlet 205.

[0041] As an optimization of the nozzle seat 3 in this embodiment, the nozzle seat 3 is rectangular, and the inner side matches the outer side wall of the inner tube 1 to form a good fit.

[0042] The nozzle holder 3 and the inner tube 1 are bonded together by glue.

[0043] The nozzle seat 3 is made of rubber. It should be noted that the material of the nozzle seat 3 in this embodiment not only needs to be able to support the nozzle 4, but also has elasticity so as to form a seal when connected with other components, that is, the material can form a good seal with the nozzle seat slot 202 of the outer tube 2, thereby effectively ensuring the airtightness of the heating chamber 203.

[0044] In addition, the thickness of the nozzle seat 3 is greater than the thickness of the heating chamber 203 , and this structure facilitates the clamping of the nozzle seat slot 202 to the nozzle seat 3 .

[0045] In this embodiment, the nozzle 4 is riveted to the nozzle through-hole unit 103 after passing through the nozzle insertion hole unit 301 , thereby enhancing the connection strength between the nozzle 4 and the inner tube 1 .

[0046] like Figure 3 As shown, in this embodiment, the nozzle through hole unit 103 includes a plurality of nozzle through holes 104 arranged in a straight line, and the nozzle insertion hole unit 301 includes a plurality of nozzle insertion holes 302 arranged in a straight line. The number of the nozzle insertion holes 302 is the same as the number of the nozzle through holes 104 .

[0047] It should be noted that the sealing seat 5 in this embodiment is a nut seat with an inner ring, which can be screwed to the thread arranged on the outer wall of the inner tube 1. After the screwing is completed, it can be welded to the plug port 201 of the outer tube 2, so that the isolated nozzle constitutes a whole, and the inner tube cavity 102 and the heating cavity 203 are isolated from each other and work independently.

[0048] 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.
