Description

Technical Field

[0001] This utility model belongs to the field of fan technology and relates to a fan housing. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. Gas pressure can convert the rotating machine into gas pressure energy and kinetic energy, and the fan rotates by delivering the gas.

[0003] Related technologies, such as Chinese Patent No. CN110939607A, disclose a fan housing. The fan housing is volute-shaped and has a volute tongue and a cavity located between an air inlet and an air outlet. The volute tongue is provided with a protrusion that is configured to extend substantially in a direction parallel to the axial direction of an impeller mounted in the cavity. The protrusion has at least one crest on the longitudinal section of the fan housing, and the crest is opposite to an annular protrusion located on the circumferential outer surface of the impeller.

[0004] Regarding the aforementioned technologies, the applicant has found that although the volute-shaped fan has the advantages of noise reduction and space reduction, after long-term use, a large amount of dirt will accumulate inside the fan casing, which is not easy to clean and affects its performance. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a fan housing that is stable and easy to install.

[0006] The objective of this utility model can be achieved through the following technical solution: A novel fan housing, comprising a fan housing assembly and a motor, wherein the fan housing assembly has an air inlet and an air outlet, characterized in that a fixing base for fixed installation is provided on the side end of the fan housing assembly, the fan housing assembly is composed of a left fan housing and a right fan housing, both of which are volute structures, and fixing rings are provided on the outer ends of the left and right fan housings. When the two are integrated, the fixing rings on the two fan housings are abutted and sealed to each other by fixing bolts. Four triangular connecting ribs are provided on the outer side of the left fan housing, and mounting parts for the fixing base to install and fix are provided on the connecting ribs. Four fixing rods protrude from the mounting parts at the lower end, and positioning holes for the fixing rods to extend and position are provided on the fixing base. Nuts are provided on each positioning rod and they are connected and fixed by a threaded structure.

[0007] In the aforementioned novel fan housing, the fixed base consists of a connecting seat and a fixed seat, which are integrally formed. A reinforcing rib with a triangular structure is provided between the connecting seat and the fixed seat. A slot is provided on one side of the connecting seat to cooperate with the left housing of the fan.

[0008] In the aforementioned novel fan housing, a stepped groove for enhanced sealing is provided on the inner wall of the right fan housing, and a stepped portion that mates with the stepped groove is provided on the inner side of the left fan housing.

[0009] In the aforementioned novel fan housing, the left fan housing is provided with a positioning part for installing a motor, and a connecting rib is also provided between the positioning part and the installation part. An opening is provided on the left fan housing, through which the motor shaft of the motor extends and connects to an impeller.

[0010] Compared with existing technologies, this new type of fan casing has a split structure, which is divided into a left fan casing and a right fan casing, making it easier for staff to perform internal maintenance. Attached Figure Description

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3As shown, this novel fan housing includes a fan housing assembly 1 and a motor. The fan housing assembly 1 has an air inlet 2 and an air outlet 3. The motor shaft extends into the fan housing assembly 1 and drives the internal impeller to operate, allowing air to enter through the air inlet 2 and exit through the air outlet 3 via the action of the impeller. A fixing base 4 is provided on the side end of the fan housing assembly 1 for fixed installation. The fan housing assembly 1 is composed of a left fan housing 5 and a right fan housing 6. Both the left fan housing 5 and the right fan housing 6 are arranged in a volute structure. A fixing ring 7 is provided on the outer end of both the left fan housing 5 and the right fan housing 6. When the two are integrated, The two fan housings have fixing rings 7 attached to each other and are sealed together by fixing bolts. The outer side of the left fan housing 5 has four triangular connecting ribs 8. The connecting ribs 8 have mounting parts 9 for mounting the fixing base 4. The mounting parts 9 at the lower end have four fixing rods 10 protruding from them. The fixing base 4 has positioning holes for the fixing rods 10 to extend and be positioned. The fixing rods 10 are integrally formed with the left fan housing 5. The fixing rods 10 pass through the positioning holes and are fixed by nuts, which enhances the stability of the fan installed on the fixing base 4. Each positioning rod is provided with a nut and is connected and fixed by a threaded structure.

[0017] To elaborate further, the fixed base 4 is composed of a connecting seat 11 and a fixed seat 12. The connecting seat 11 and the fixed seat 12 are integrally formed. A reinforcing rib 13 with a triangular structure is provided between the connecting seat 11 and the fixed seat 12. A slot is provided on one side of the connecting seat 11 to cooperate with the left housing 5 of the fan.
