Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, and more specifically to the technical field of a noise reduction type humidifier. Background Art

[0002] A humidifier is a household appliance that increases the humidity in a room. It can humidify a specific room or connect to a boiler or central air conditioning system to humidify an entire building. The humidifier industry has a nearly 20-year history in China. After years of understanding air quality concepts, product development, and market cultivation, the functions and uses of this relatively unfamiliar small appliance are gradually gaining acceptance. Existing patents disclose the following technologies:

[0003] The patent, publication number CN110410911A, titled "A Humidifier Housing Structure and Humidifier," discloses the following: The housing structure of the humidifier includes: a housing, within which is formed a sterilization cavity for mounting a sterilization element and an atomization cavity for mounting an atomization element, the sterilization cavity being in communication with the atomization cavity; and a reflector, disposed within the sterilization cavity so as to reflect the sterilization light emitted by the sterilization element. When in use, the housing structure and humidifier reflect the sterilization light emitted by the sterilization element through the reflector, and the reflected light can sterilize the water in the sterilization cavity again, thereby improving the sterilization effect.

[0004] The patent with publication number CN118391761A and patent name "Humidifier" discloses the following content: The humidifier includes a shell, an airflow generating device, a water pump device, and a water film mechanism. The shell has a storage space, an air inlet and an air outlet and is interconnected. The air outlet side of the airflow generating device faces the storage space to drive the airflow in the storage space to flow out through the air outlet. The water pump device is installed in the shell and connected to the water tank. The water film mechanism is arranged in the storage space and connected to the water pump device. The water film device is provided with a water guide channel and a water outlet channel. The water guide channel is connected to the water pump device and is connected to the storage space through the water outlet channel. The water pump device is used to pump liquid water in the water tank into the water guide channel. The liquid water in the water guide channel is discharged through the water outlet channel and evaporates to form gaseous water. The above-mentioned humidifier does not need to be provided with a conventional wet curtain assembly, thereby reducing production costs and achieving the purpose of humidification without consumables and odor.

[0005] The humidifiers disclosed in the prior art and the above patents have the defects of being noisy, having no noise reduction components, and having low heating efficiency. Utility Model Content

[0006] The purpose of the present invention is to provide a noise reduction humidifier in order to solve the above technical problems.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] The utility model provides a noise reduction humidifier, including a heater main body, the heater main body including an outer shell with an opening upward, a heating cavity arranged in the outer shell, a control cavity arranged at the bottom of the heating cavity and a sealing cover arranged at the top of the outer shell, a split cover which can reduce noise and increase efficiency is arranged in the middle of the heating cavity, the split cover divides the heating cavity into an external water inlet cavity and an internal intermediate heating steam cavity, the water inlet cavity is connected with the bottom of the intermediate heating steam cavity, a humidification outlet is arranged on the sealing cover, and an arc-shaped outlet channel connected with the humidification outlet is arranged on the top of the side wall of the split cover.

[0009] Specifically, the split cover divides the traditional heating chamber into two chambers, the external water inlet chamber and the internal intermediate heating steam chamber. The heating plate mainly heats the intermediate heating steam chamber. Since the amount of heated water is reduced, the heating speed can be increased, the efficiency during use is improved, and energy can be saved. The key is that the addition of the split cover can effectively reduce noise and play a partial silencing role. The noise is reduced from the original 65 decibels to the current 45 decibels.

[0012] In one embodiment, a downwardly recessed water level detection groove is further provided at the bottom of the water inlet chamber, a water level detection sensor is installed in the water level detection groove, and the water level detection sensor is electrically connected to the PLC controller.

[0013] Specifically, when the water level detection sensor detects that there is no water in the water inlet chamber, it transmits the water shortage signal to the PLC controller. The PLC controller controls the water pump to add water in a fixed amount to ensure that there is water in the water inlet chamber and enters the intermediate heating steam chamber to avoid dry burning and damage to the equipment.

[0014] In one embodiment, the heating cavity is a cylindrical heating cavity, the middle part of the cylindrical heating cavity is recessed downward to form an intermediate cavity base, an integrally formed annular partition plate is provided on the side wall of the intermediate cavity base, the partition cover is a cylindrical partition cover, the cylindrical partition cover is detachably mounted on the annular partition plate, a sealing ring is provided between the cylindrical partition cover and the annular partition plate, and a water hole is provided at the bottom of the annular partition plate.

[0015] In one embodiment, the intermediate chamber base, the annular partition plate and the cylindrical partition cover form an intermediate heating steam chamber.

[0016] In one embodiment, the cover is detachably mounted on the top of the housing, and a sealing ring is provided at the connection between the cover and the housing.

[0017] In one embodiment, a portion of the humidification outlet is located on the top of the housing, and another portion is located on the cover.

[0018] In one embodiment, the water storage tank is detachably connected to the bottom of the housing.

[0019] In one embodiment, a power cord and a start button are provided on the housing, the power cord is connected to an external power source, and the start button is electrically connected to a PLC controller.

[0020] The beneficial effects of the utility model are as follows:

[0021] 1. The utility model has a reasonable design. The split cover divides the traditional heating chamber into two chambers, the external water inlet chamber and the internal intermediate heating steam chamber. The heating plate mainly heats the intermediate heating steam chamber. Since the amount of heated water is reduced, the heating speed can be increased, the efficiency during use is improved, and energy can be saved. The key is that the addition of the split cover can effectively reduce noise and play a partial silencing role. The noise is reduced from the original 65 decibels to the current 45 decibels.
