Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] Such as Figure 9 , Figure 10 , Figure 12 , Figure 14 As shown, the present invention provides a casing 100, including: an internally sealed casing 110; a functional hole (blocked by the air filter cover 120, not shown) provided on the casing 110, communicating with the inside of the casing 110 and External: a functional module, selectively detachably installed at the functional hole to detect the sealing state of the housing or maintain the air pressure balance inside and outside the housing.

[0039] optional, see Figure 1-Figure 4 , when the functional module is the air filter cover 120, the air pressure inside and outside the housing 110 can be balanced when the mower is working. The air filter cover 120 includes a base 121 ins...

Abstract

The invention provides a machine shell and a mower. The machine shell comprises a shell body with the sealed interior, a functional hole and a functional module; the machine shell is located at the outer side of a main body part of the mower; the functional hole is formed in the shell body and is communicated with the interior and the exterior of the shell body; and the functional module is selectively and detachably mounted at the functional hole so as to detect the sealing state of the shell body or maintain air pressure balance inside and outside the shell body. Compared with the prior art, the mower has the advantages that the functional hole is formed in the shell body, so that the functional module can be selectively mounted through the functional hole, an air filter cover or an airtight filling nozzle can be selected to be mounted at the functional hole according to needs, and the sealing state of the mower can be conveniently detected or the air pressure balance inside and outside the shell body of the mower can be conveniently realized.

Description

technical field [0001] The invention relates to a casing and a lawnmower, in particular to a structure for detecting the airtightness of the lawnmower and balancing the internal and external air pressure of the lawnmower. Background technique [0002] The smart lawn mower is a robot for maintaining the lawn. It has the advantages of intelligence, modernization, environmental protection, and hands-free. It is more and more favored by the market and consumers. Since the smart lawn mower has the characteristics of working independently outdoors, it is particularly important to protect against moisture in rainy and humid weather, so all combined parts of the fuselage need to be sealed. [0003] However, when there are many sealing parts, it may be missing. If the sealing is too good, the gas in the cavity of the intelligent lawn mower will expand or contract with temperature changes and then exert pressure on the casing. Contents of the invention [0004] The object of the pr...
