In the process that the second pressing portion 230 approaches the pressure sensing paper 300, the pressing surface of the second pressing portion 230, that is, the second pressing surface 210, is disposed on a side of the second pressing portion 230 away from the second receiving portion 220 and is used for pressing the pressure sensing paper 300, so that in the process that the driving part drives the second receiving portion 220 to approach the pressure sensing paper 300, the second pressing portion 230 is driven to approach the pressure sensing paper 300, and thus the second pressing surface 210 on the second pressing portion 230 approaches the pressure sensing paper 300, thereby facilitating the pressing of the pressure sensing paper 300.
In one embodiment, at least one second groove 232 is formed on one side of the second pressing portion 230 close to the first sealing head 100. The second groove 232 opens toward the first end cap 100. In this embodiment, since the second pressing portion 230 is used for pressing the pressure sensing paper 300, in the pressing process, when the second pressing surface 210 of the second pressing portion 230 completely presses the pressure sensing paper 300, that is, the second pressing surface 210 presses the pressure sensing paper 300 in parallel, so that the pressure of the contact position between the second pressing portion 230 and the pressure sensing paper 300 is less than the external atmospheric pressure, that is, the pressure between the second pressing portion 230 and the pressure sensing paper 300 is less than the atmospheric pressure, that is, the pressure between the second pressing portion 230 and the pressure sensing paper 300 is too tight, so that when the second pressing portion 230 is far away from the first sealing head 100, a part of the pressure sensing paper 300 is easily adhered to the second pressing portion 230, thereby damaging the pressure sensing paper 300. In order to reduce the occurrence probability of the above situation, the second groove 232 is disposed on the second pressing portion 230, and the opening of the second groove 232 faces the first sealing head 100, so that a gap exists between the second pressing portion 230 and the pressure sensing paper 300, and the probability of over-tightness between the second pressing portion 230 and the pressure sensing paper 300 is reduced, so that when the second pressing portion 230 is far away from the first sealing head 100, the pressure sensing paper 300 is conveniently separated from the second pressing portion 230, the probability of damage caused by tearing of the pressure sensing paper 300 by the second pressing portion 230 is reduced, and the service lives of the second sealing head 200 and the pressure sensing paper 300 are prolonged.
