[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. The components of the embodiments of the present utility model usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0025] Embodiment 1. In this embodiment, as Figure 1 shown, a portable power source device for industrial measurement includes a housing 5. A battery pack 3 and a blower 6 are arranged inside the housing 5, and the battery pack 3 and the blower 6 are electrically connected; there are two openings on the housing 5, and a rear cover plate 1 and a front cover plate 10 are respectively arranged at the openings. A plurality of air inlet holes are provided on the rear cover plate 1.

[0026] In this embodiment, the blower 6 is driven by the battery pack 3 to operate, so that the blower generates cooling air, and then the air outlet is aligned with the equipment instrument for cooling, or after being connected by a hose, the designated position is cooled.

[0027] In one or more embodiments of the present utility model, a handle 4 is fixed outside the housing 5.

[0028] In this embodiment, through the setting of the handle 4, the device is convenient to carry.

[0029] In one or more embodiments of the present utility model, an air duct gap is formed between the battery pack 3 and the inner wall of the housing 5. One end of the air duct gap is communicated with the air inlet holes, and the other end is communicated with the air inlet end of the blower 6.

[0030] In this embodiment, through the setting of the air duct gap, the air flow rate is enhanced and the temperature is reduced before the air is sucked by the blower 6, so that the air cools the battery pack 3 and the blower 6 itself to a certain extent on this path.

[0031] In one or more embodiments of the present utility model, the rear cover plate 1 is clamped at an opening on one side of the housing 5. A filter cotton 2 is provided on the inner side of the rear cover plate 1. A partition plate 51 is also fixed inside the housing 5. A plurality of ventilation holes are formed in the partition plate 51. The partition plate 51 is located inside the filter cotton 2 and limits its position.

[0032] In this embodiment, the housing 5 has a cuboid structure with a cavity inside. The two outer ends in the length direction are not open, so there is enough space to place a large-capacity battery pack 3. Through the arrangement of the filter cotton 2, the device filters the air first under the working conditions of a high particulate dust environment, so that external particulate dust will not easily accumulate in the battery pack 3 and the fan 6, thereby extending the service life. Through the arrangement of the partition plate 51, it is convenient to limit and fix the position of the filter cotton 2. Through the arrangement of the ventilation holes, the air flow is not affected.

[0033] In one or more embodiments of the present utility model, a fixing box is fixed on the inner side of the rear cover plate 1. A lock block 100 is slidably arranged inside the fixing box. A compression spring 101 is also fixed inside the fixing box. The inner end of the lock block 100 abuts against the compression spring 101. A lock groove is formed on the inner wall of the housing 5. The extended end of the lock block 100 passes through the fixing box and is adapted to the lock groove. A finger hole is also formed in the rear cover plate 1. The lock block 100 is located inside the finger hole.

[0034] In this embodiment, a rectangular frame is fixed at the opening of the housing 5. A first step surface is formed on the inner side of the rectangular frame. A second step surface is formed on the inner edge of the rear cover plate 1. The first step surface and the second step surface are engaged with each other. Through the engagement, the rear cover plate 1 is convenient for installation and disassembly. The fixing box is fixed on the inner side of the rear cover plate 1 by bolts. A cross plate is fixed in the middle of the fixing box. The cross plate divides the inside of the fixing box into two cavities. Two lock blocks 100 are provided and are respectively arranged in the cavities. One end of the compression spring 101 abuts against the cross plate. A spring groove is formed at the inner end of the lock block 100. The other end of the compression spring 101 is located in the spring groove. Through holes are formed on the upper and lower sides of the fixing box. The locking end of the lock block 100 has a protruding lock tongue. The lock tongue is adapted to the through holes and the lock groove. Under the action of the spring, the lock tongue passes through the through holes and extends into the lock groove to fix the rear cover plate 1. Two finger holes are formed. Through the arrangement of the two finger holes, it is convenient for manual operation to move the lock block 100 inward, so that the lock tongue retracts, and it is convenient to remove the rear cover plate 1 to replace the filter cotton 2.

[0035] In one or more embodiments of the present utility model, a cooling air outlet 12 is fixed on the side surface of the housing 5. The cooling air outlet 12 is communicated with the air outlet end of the fan 6.

[0036] In one or more embodiments of the present utility model, a display panel 7 for displaying the power information of the battery pack 3, a power switch 8 for controlling the fan 6, a charging port 9 for charging the battery pack 3, and a DC power supply port 11 for providing DC power supply to the outside are installed on the front cover plate 10.

[0037] The working principle of the present utility model:

[0038] When the device works, the working flow direction of the air flow is as follows: After the ambient air enters through the air inlet control holes of the rear cover plate 1, it passes through the filter cotton 2 to filter out the particulate dust in the air; then the air flow flows along the air duct gap between the battery pack 3 and the housing 5 to the suction port of the fan 6, and finally discharges from the cooling air outlet 12; such a design of the air flow direction can not only achieve efficient filtration of the air, but also achieve the purpose of cooling the battery pack 3 and the fan 6; the filter cotton 2 is designed for quick replacement or maintenance, and the rear cover plate 1 is a quick-release structure. After it is taken out, the filter cotton 2 can be directly taken out for replacement or dust cleaning and maintenance operations.
