[0028] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. Example 1:

[0029] See Figures 1 and 2 of the specification: A disposable manual razor with self-heating shaving liquid, comprising a handle 1 and a cutter head 2; when not in use, the handle 1 and the cutter head 2 are separated; when in use, the cutter head 2 is fixedly connected to the front end of the handle 1;

[0030] See Figures 3 and 4 of the specification: the cutter head 2 includes a cutter head frame 2.1, a blade 2.2, a liquid outlet plate 2.3, a wiping strip 2.4, a pressure liquid storage bag 2.5, and a water-self-heating material 2.1.1.1; the upper part of the cutter head frame 2.1 is provided with a liquid storage cavity 2.1.1, a wiping strip cavity 2.1.2, and a blade groove 2.1.3; the lower part of the cutter head frame 2.1 is provided with a cutter head frame connecting neck 2.1.4, which is a hollow structure with a liquid inlet connector 2.1.4.1 inside. The connector 2.1.4.1 is connected to the liquid storage chamber 2.1.1, and a snap-fit ​​structure is provided at the lower portion of the connecting neck 2.1.4 of the cutter head holder. The water-self-heating material 2.1.1.1 is disposed in the liquid storage chamber 2.1.1. The liquid outlet plate 2.3 is fixedly disposed in the upper portion of the liquid storage chamber 2.1.1. The blade 2.2 is fixedly disposed in the blade slot 2.1.3. The wiping strip 2.4 is fixedly disposed in the wiping strip chamber 2.1.2. A plurality of through holes are arranged in an array on the liquid outlet plate 2.3 and connected to the upper surface of the cutter head holder 2.1.

[0031] The pressure reservoir 2.5 is made of silicone or rubber material with good flexibility and has a hollow structure inside. Shaving liquid is injected into the pressure reservoir 2.5 under pressure, and the pressure reservoir 2.5 expands and becomes larger, exerting pressure on the shaving liquid stored therein; when the manual shaver is not in use, the pressure reservoir 2.5 is set in the hollow structure of the blade head frame connecting neck 2.1.4, and the liquid inlet connector 2.1.4.1 is not connected to the pressure reservoir 2.5; when the manual shaver is used, the blade head 2 is fixedly clamped to the front end of the handle 1. A boss is provided in the middle of the front end of the handle 1. The boss pushes the pressure reservoir 2.5 to move deep into the hollow structure of the blade head frame connecting neck 2.1.4, so that the liquid inlet connector 2.1.4.1 pierces the pressure reservoir 2.5. At this time, the shaving liquid stored in the pressure reservoir 2.5 enters under the action of pressure. The liquid storage chamber 2.1.1 is in contact with the water-sensitive self-heating material 2.1.1.1 therein; the moisture in the shaving liquid causes the water-sensitive self-heating material 2.1.1.1 to generate heat to heat the shaving liquid, and the heated shaving liquid is then released to the upper surface of the cutter head 2 through the through holes on the liquid outlet plate 2.3. Therefore, there is no need to apply shaving liquid on the face in advance before shaving. At the same time, the heated shaving liquid will better soften the beard, making the shaving effect better; the shaving liquid remaining on the face during shaving is wiped clean by the wiping strip 2.4 made of absorbent sponge material; in addition, in order to ensure smooth liquid discharge from the cutter head 2, the outer surface of the liquid outlet plate 2.3 is provided with a plurality of ridges parallel to the through holes arranged in the array, and the through holes are arranged in the grooves of two adjacent ridges (that is, the outlet of the through hole is lower than the upper surface of the ridge) to prevent the facial skin from clogging the through hole and causing poor liquid discharge during shaving.
